<br />
==Moon solstice picnic - Saturday 22nd==<br />
<br />
Friends of mine from Santa Fe have invited me for a hike & picnic Saturday evening, to watch the year's biggest moon rise on the hill behind st john's. They're very generous people, and when I told them about the school they insisted that I bring friends along. Since they'll cook and bring the food, I think I cannot reasonably invite more than 4 people though. Write your name and join us! (Meeting at 6:30pm at the fish pond) --Matteo<br />

==Museum Hill - Saturday 22nd (or Sunday 23rd)==<br />
Would anyone be interested in checking out some of the museums on "Museum Hill" near St. John's? The day is flexible, if people going to Tent Rocks are also interested.<br />
I propose Saturday 10AM departure - it's within walking distance so anyone can come later as well.<br />
Possible museums include:<br />
Museum of International Folk Art, <br><br />
Museum of Indian Arts & Culture, <br><br />
Wheelwright Museum of the American Indian <br><br />
Here is some [http://www.santafenm.info/museums.htm more info about the museums].<br />
Anyone interested? --Molly<br />
<br />
==Tent Rocks National Monument on Saturday 22nd==<br />
I would like to propose a field trip next Saturday (the 22nd), to visit the [http://www.blm.gov/nm/st/en/prog/recreation/rio_puerco/kasha_katuwe_tent_rocks.html Tent Rocks National Monument], which should be a very beautiful place.<br />

==June 21 Madrid to see Juniper's Brother's band and to dance with hippies==<br />
<br />
My brother's band [http://www.reverbnation.com/toddandthefox Todd and the Fox] is playing at the Mine Shaft in Madrid on June 21. Madrid is a ridiculous hippy town and has some of the best people watching there is. To boot, my brother's band is awesome and we can dance and have a great time http://www.reverbnation.com/show/10280700 --Juniper<br />
<br />
Thumbs up!! -- [[Luís_Seoane | Luíño]]<br />
<br />
Sounds great to me!! -- [[Jody_Wright | Jody]]<br />
<br />
Sounds fun! I'd love to go. -Molly<br />
<br />
I'm in too! -- Kevin<br />
<br />
Sounds good! -- Melinda<br />
<br />
I'm in too! -- Elisa<br />
<br />
I'm in too! -- Johannes<br />
<br />
I guess we have to rent cars in order to get there. Anybody wants to organize this? -- Kerstin<br />
<br />
I'm in too! -- Filipe<br />
<br />
Sorry this is kind of far and my car is already full, so you all will need to self organize for this one. I'll probably get there around 8:30 or so and maybe eat at the [http://www.thehollarrestaurant.com/ Holler] before hand, it's really yummy fancy southern food --Juniper<br />
<br />
Is anyone with a car planning to go to this concert tonight? If yes, would you be willing to volunteer spaces in your car here and people can sign up? [[Jody_Wright | Jody]]<br />
<br />
==More Games!==<br />
<br />
So... I was thinking it might be fun to have a second games night some time this week- either to catch up on the Mafia/werewolf game that we didn't have on Sunday, or perhaps some other game. Some of you may have encountered [[That Game]]... which is as always being updated and altered. If you missed out on the first round, or want to play again (or simply want a chance to watch JP dissolving in laughter) then come along.<br />
As for Time/Place... Ummm... I feel like Thursday evening might be good, perhaps upstairs lower common room... but if other times/day/place suggested then that's good too.<br />
<br />
==Bandelier Field Trip==<br />
<br />
We're taking a trip to [http://www.nps.gov/band/index.htm Bandelier National Monument] on Saturday June 8th. Please visit the <b>[[Bandelier 2013 | Bandelier Field Trip]]</b> Page to sign up!<br />
<br />
==More Hiking!==<br />
<br />
Check the [[Complex Systems Summer School 2013-Hiking]] page to see current plans!<br />
<br />
<br />
Didn't get enough hiking at Bandelier? Come hiking/camping with me! I plan on going on a long hike (all day, preferably 10+ miles) one of the next two weekends. I brought things for camping and would love to do that if there is interest and it is possible to rent tents/sleeping bags in town (or if people want to just sleep outside, also fun). If that is not really possible or people would rather just go for a single day that is great as well. I am open to a lot of different things, there is so much great hiking around Santa Fe! <br />
<br />
Some suggestions:<br />
* [http://www.backpacker.com/april_1999_destinations_new_mexico_pecos_wilderness/destinations/696 Pecos Wilderness] - just outside of Santa Fe, lots of trails! <br />
* [http://www.summitpost.org/wheeler-peak-nm/150429 Wheeler Peak] - tallest mountain in New Mexico, outside of Taos (would require either camping at the base or waking up very early to do it the day of) <br />
** Near Taos we can find these [https://www.google.com/maps/preview#!data=!4m18!3m17!1m1!1sSanta+Fe+Institute%2C+1399+Hyde+Park+Road%2C+Santa+Fe%2C+New+Mexico!1m5!1sManby+Hot+Springs!2s0x87177428acfba0e5%3A0x69769a1d19abcbff!3m2!3d36.5083168!4d-105.7242545!3m8!1m3!1d10957!2d-105.7242545!3d36.5083162!3m2!1i1366!2i656!4f13.1&fid=0 hotsprings]!!!!!!! <br />
* [http://www.fodors.com/world/north-america/usa/new-mexico/taos/review-465844.html Carson National Forest] - North of Santa Fe, another beautiful forest, lots of different entrance locations <br />
<br />
I am up for any other suggestions if people have heard of trails they want to go on. Depending on how the fires progress we may or may not be limited, but should be able to do something! Send me an email if you are interested and we can talk logistics (bstoll1234@gmail.com) [[Brady_Stoll|Brady]]<br />
<br />
I would love to go! I had a hike in mind too--Tesuque Peak, which is just by the ski area and is 12 miles, but I am up for any of them! -Lauren (lash1937@gmail.com)<br />
<br />
I'm interested! -Hua (caih@umich.edu)<br />
<br />
I'm defintley interested - Wheeler Peak sounds very interesting (I have to get camping stuff though)! - johannes (johannes dot schmidt at boku dot ac dot at)<br />
<br />
If we did Wheeler Peak, I am highly in favor of the longer class 1 route. The shorter class 2 route has a scree slope at the end, and I really dislike scree (it scares me). If we camped at the trailhead, I have a 3 person tent that we could use. --Lauren<br />
<br />
If you'd like a similar experience to Wheeler Peak, but a lot closer, I recommend Santa Fe Baldy (12600'). Well above treeline, with fantastic vistas in all directions. The trailhead is only about 20 minutes away at the Santa Fe Ski Basin. The roundtrip hike is about 14 miles, making it a reasonable day hike. As always with any mountain around here, you need to be off the exposed sections by about 2PM because of the danger from thunderstorms! --John L<br />
<br />
More hiking would rock!(Although I'm not sure about optimal length...) --Todd<br />
<br />
==Music on the Hill==<br />
<br />
St. John's hosts [http://www.stjohnscollege.edu/events/SF/music.shtml live music] on the soccer field this Wednesday (June 12) as well as next Wednesday (June 19) and the Wednesday after (June 26). Performances start around 6:00 PM. It looks like all of the performers will be doing jazz. I really hope to make the June 19 performance, as this will be big band, which is (usually) great for dancing. Any other swing dancers in our group? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
* sounds fun to me! -- Hua<br />
* I'm definitely interested! --Molly<br />
* Sounds fun to me as welll! --Brady<br />
* Sounds fun! --Jody<br />
<br />
==Mafia/Werewolf==<br />
[[JP]] LOVES to Play [http://en.wikipedia.org/wiki/Mafia_(party_game) Mafia/Werewolf]. Let's set up a time one of these evenings in the lower commons...<br />
<br />
This sounds pretty cool. [[todd_bodnar | Todd]]<br />
<br />
I like Mafia a lot, and I also brought a card game called [http://en.wikipedia.org/wiki/Fluxx Fluxx], and also know a few other games you can play with just paper and pencil (like [http://natsdistractions.wordpress.com/2009/12/13/great-party-game/ Bucket of Nouns]). I think a game night would be fun! --Molly<br />
<br />
I would love to play Go if anyone is interested. --John D -- Count me in!! -- [[Luís_Seoane | Luíño]]<br />
<br />
We should probably set a time/day/place if we actually want this to happen... I suggest 7:00am on sunday, with the lower common room thing, unless something else is happening then.<br />
<br />
I like the game! Count me in! -- Hua<br />
<br />
==Dance party==<br />
<br />
Would anyone be interested in some sort of clubbing/dance party some time this month? And to be clear I don't mean going down to a bar to sit round drinking beers- that can be fun too, but I'm meaning something more music/dance focused. <br />
If so, <br />
<br />
What bars/clubs do people know of the might work? what music do they provide? <br />
<br />
What music are people interested in? Remember, music that is good to listen to is not always good for dancing (and to be fair, there's plenty of music which is fun to dance to, but might not actually be "good")<br />
<br />
Also, didn't someone mention some degree of DJing or music abilities? I can't remember, but if so, we could try to get our hands on the light rigs in the lecture hall and just make our own dance part from scratch...<br />
<br />
*Our own dance party from scratch sounds fun to me. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
So, some investigation indicates that hosting a large scale party at St Johns could be fairly impossible. She suggested hiring a venue in town... but I figure if that's the case we might as well just head down there and take it over by force of numbers.<br />
<br />
*There is a CSSS "Dance with Breadloaf workshop" scheduled for June 22 starting at 8:00 PM. Is this an actual dance, or is this a complexity science thing??? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
==Mountain Biking==<br />
<br />
I would like to go mountain biking on sunday (9th of June). Anybody interested in joining me? We can rent a bike in the city for either 30$ (hard tail) or 60$(fully), helmets are 4$ extra. For those who are interested: please put your name and your height (needed for bike reservation) here until Thursday evening, I'm going to reserve the bikes then. [[Johannes_Schmidt]]<br />
<br />
<br />
==Athletic Things==<br />
<br />
I've heard lots of people talking about running/walking etc, and at dinner last night we mentioned that it would be fun to have a running group. Anyone interested in having a running/walking group either in the mornings or evenings? Post interest here!<br />
<br />
I'm interested in a (quick) '''walking group''' in the mornings. It's great to exercise a bit in this nice weather and be able to talk at the same time. [[Regina_Martinez |Regina]]<br />
*I would also be up for quick walking - whether we mean walking briskly or walking for 20-30 min. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
<br />
Also, I love ultimate frisbee! Anyone interested in either learning or playing a game perhaps sunday or after dinner one day next week? Let me know! [[Brady_Stoll|Brady]]<br />
*Ultimate would be fun, although I had a pretty bad knee injury years ago and haven't done that much running since then. I could see how long I would last. --[[Vanessa_Schweizer | Vanessa]]<br />
*That's fine, anything would be fun, even just throwing/teaching people to throw! -Brady<br />
* Down to play. Anything planned for today? - Bapu<br />
* I don't have any specific plans today, but would love to either throw or teach if you're interested before the sun goes down. Play for sure tomorrow? Lets say tomorrow after dinner for those interested<br />
*'''Lets play frisbee today! (Wed) Meet after dinner and we'll walk over to the fields, or meet us there!'''<br />
<br />
Or basketball? Anybody want to play a pickup game?<br />
-I would play a pick up game -Brady<br />
<br />
==Yoga==<br />
<br />
Anyone interested in '''yoga tomorrow (Sunday 9th) at 7pm?''' Some of us are going to [[http://www.santafecommunityyoga.org/index.php/classes2/schedule]]. We are meeting at 6:30pm. There is only one more space in Lauren's car. But, if there are more people interested, we can try to find a solution for the commute. [[Regina_Martinez | Regina]]<br />
<br />
Hi Regina - I would be interested in joining you for yoga if there is still space. Please email me at [[jjwright49@me.com]] and let me know. Thanks! - [[Jody_Wright | Jody]]<br />
<br />
Anyone want to go to yoga tomorrow (Tuesday the 11th) evening? We were thinking of going to Hatha yoga at 5:30, so leaving campus at 5:00. We'll go to dinner afterwards too. Send me an email (lash1937@gmail.com) if interested. [[Lauren_Shoemaker | Lauren]]<br />
<br />
==Sightseeing Weekend==<br />
<br />
Anyone interested in going on a weekend road trip? This could be more of an 'easy going' option to the hiking trip proposed above. I was thinking of maybe driving up to Taos and doing some whitewater rafting and general sightseeing. Let me know if you are interested or have any other ideas. I don't have a car but am able to drive...<br />
<br />
- [[Ivana_Stankov | Ivana]]<br />
<br />
==THERE IS A FOURTH WEEKEND!!==<br />
<br />
If you, like me, believe that CSSS lives on after Saturday 29...<br />
<br />
If you, like me, are hanging around because you can't leave this sacred piece of ground anymore... <br />
<br />
If you, like me, believe this month is only the beginning of a life that wasn't before... <br />
<br />
<br />
Then you believe on the forth weekend!! I know many of you will stay a few days after CSSS is over and it would be nice to organize ourselves soon. So, if we choose to go somewhere, say taking a flight, we could get cheaper prices, etc! Also we will be needing shelter after the 29th. This might be an urgent thing ;) Let's use this to organize ourselves! I post some ideas below that I've heard around these days. -- [[Luís_Seoane | Luíño]]<br />
<br />
<br />
*Trip to the Gran Canyon? <br />
*Camping in some national park? <br />
*Trip to San Francisco? <br />
*Trip to Las Vegas where we make up random couples and get married :?<br />
<br />
I vote for Grand Canyon + San Francisco. I have my plane back home from Albuquerque on the 7th of July, so I am totally in for post school plans! -- Elisa<br />
<br />
If you come to San Francisco, I can probably show you some cool places. --[[Nix_Barnett | Nix]]<br />
<br />
<br />
==Indoor climbing/bouldering on saturday (22)==<br />

==Moon solstice picnic - Saturday 22nd==<br />
<br />
Friends of mine from Santa Fe have invited me for a hike & picnic Saturday evening, to watch the year's biggest moon rise on the hill behind st john's. They're very generous people, and when I told them about the school they insisted that I bring friends along. Since they'll cook and bring the food, I think I cannot reasonably invite more than 4 people though. Write your name and join us! --Matteo<br />

==June 21 Madrid to see Juniper's Brother's band and to dance with hippies==<br />
<br />
My brother's band [http://www.reverbnation.com/toddandthefox Todd and the Fox] is playing at the Mine Shaft in Madrid on June 21. Madrid is a ridiculous hippy town and has some of the best people watching there is. To boot, my brother's band is awesome and we can dance and have a great time http://www.reverbnation.com/show/10280700 --Juniper<br />
<br />
Thumbs up!! -- [[Luís_Seoane | Luíño]]<br />
<br />
Sounds great to me!! -- [[Jody_Wright | Jody]]<br />
<br />
Sounds fun! I'd love to go. -Molly<br />

<br />
Sorry this is kind of far and my car is already full, so you all will need to self organize for this one. I'll probably get there around 8:30 or so and maybe eat at the [http://www.thehollarrestaurant.com/ Holler] before hand, it's really yummy fancy southern food --Juniper<br />
<br />
Is anyone with a car planning to go to this concert tonight? If yes, would you be willing to volunteer spaces in your car here and people can sign up? [[Jody_Wright | Jody]]<br />
<br />
==More Games!==<br />
<br />
So... I was thinking it might be fun to have a second games night some time this week- either to catch up on the Mafia/werewolf game that we didn't have on Sunday, or perhaps some other game. Some of you may have encountered [[That Game]]... which is as always being updated and altered. If you missed out on the first round, or want to play again (or simply want a chance to watch JP dissolving in laughter) then come along.<br />
As for Time/Place... Ummm... I feel like Thursday evening might be good, perhaps upstairs lower common room... but if other times/day/place suggested then that's good too.<br />
<br />
==Bandelier Field Trip==<br />
<br />
We're taking a trip to [http://www.nps.gov/band/index.htm Bandelier National Monument] on Saturday June 8th. Please visit the <b>[[Bandelier 2013 | Bandelier Field Trip]]</b> Page to sign up!<br />
<br />
==More Hiking!==<br />
<br />
Check the [[Complex Systems Summer School 2013-Hiking]] page to see current plans!<br />
<br />
<br />
Didn't get enough hiking at Bandelier? Come hiking/camping with me! I plan on going on a long hike (all day, preferably 10+ miles) one of the next two weekends. I brought things for camping and would love to do that if there is interest and it is possible to rent tents/sleeping bags in town (or if people want to just sleep outside, also fun). If that is not really possible or people would rather just go for a single day that is great as well. I am open to a lot of different things, there is so much great hiking around Santa Fe! <br />
<br />
Some suggestions:<br />
* [http://www.backpacker.com/april_1999_destinations_new_mexico_pecos_wilderness/destinations/696 Pecos Wilderness] - just outside of Santa Fe, lots of trails! <br />
* [http://www.summitpost.org/wheeler-peak-nm/150429 Wheeler Peak] - tallest mountain in New Mexico, outside of Taos (would require either camping at the base or waking up very early to do it the day of) <br />
** Near Taos we can find these [https://www.google.com/maps/preview#!data=!4m18!3m17!1m1!1sSanta+Fe+Institute%2C+1399+Hyde+Park+Road%2C+Santa+Fe%2C+New+Mexico!1m5!1sManby+Hot+Springs!2s0x87177428acfba0e5%3A0x69769a1d19abcbff!3m2!3d36.5083168!4d-105.7242545!3m8!1m3!1d10957!2d-105.7242545!3d36.5083162!3m2!1i1366!2i656!4f13.1&fid=0 hotsprings]!!!!!!! <br />
* [http://www.fodors.com/world/north-america/usa/new-mexico/taos/review-465844.html Carson National Forest] - North of Santa Fe, another beautiful forest, lots of different entrance locations <br />
<br />
I am up for any other suggestions if people have heard of trails they want to go on. Depending on how the fires progress we may or may not be limited, but should be able to do something! Send me an email if you are interested and we can talk logistics (bstoll1234@gmail.com) [[Brady_Stoll|Brady]]<br />
<br />
I would love to go! I had a hike in mind too--Tesuque Peak, which is just by the ski area and is 12 miles, but I am up for any of them! -Lauren (lash1937@gmail.com)<br />
<br />
I'm interested! -Hua (caih@umich.edu)<br />
<br />
I'm defintley interested - Wheeler Peak sounds very interesting (I have to get camping stuff though)! - johannes (johannes dot schmidt at boku dot ac dot at)<br />
<br />
If we did Wheeler Peak, I am highly in favor of the longer class 1 route. The shorter class 2 route has a scree slope at the end, and I really dislike scree (it scares me). If we camped at the trailhead, I have a 3 person tent that we could use. --Lauren<br />
<br />
If you'd like a similar experience to Wheeler Peak, but a lot closer, I recommend Santa Fe Baldy (12600'). Well above treeline, with fantastic vistas in all directions. The trailhead is only about 20 minutes away at the Santa Fe Ski Basin. The roundtrip hike is about 14 miles, making it a reasonable day hike. As always with any mountain around here, you need to be off the exposed sections by about 2PM because of the danger from thunderstorms! --John L<br />
<br />
More hiking would rock!(Although I'm not sure about optimal length...) --Todd<br />
<br />
==Music on the Hill==<br />
<br />
St. John's hosts [http://www.stjohnscollege.edu/events/SF/music.shtml live music] on the soccer field this Wednesday (June 12) as well as next Wednesday (June 19) and the Wednesday after (June 26). Performances start around 6:00 PM. It looks like all of the performers will be doing jazz. I really hope to make the June 19 performance, as this will be big band, which is (usually) great for dancing. Any other swing dancers in our group? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
* sounds fun to me! -- Hua<br />
* I'm definitely interested! --Molly<br />
* Sounds fun to me as welll! --Brady<br />
* Sounds fun! --Jody<br />
<br />
==Mafia/Werewolf==<br />
[[JP]] LOVES to Play [http://en.wikipedia.org/wiki/Mafia_(party_game) Mafia/Werewolf]. Let's set up a time one of these evenings in the lower commons...<br />
<br />
This sounds pretty cool. [[todd_bodnar | Todd]]<br />
<br />
I like Mafia a lot, and I also brought a card game called [http://en.wikipedia.org/wiki/Fluxx Fluxx], and also know a few other games you can play with just paper and pencil (like [http://natsdistractions.wordpress.com/2009/12/13/great-party-game/ Bucket of Nouns]). I think a game night would be fun! --Molly<br />
<br />
I would love to play Go if anyone is interested. --John D -- Count me in!! -- [[Luís_Seoane | Luíño]]<br />
<br />
We should probably set a time/day/place if we actually want this to happen... I suggest 7:00am on sunday, with the lower common room thing, unless something else is happening then.<br />
<br />
I like the game! Count me in! -- Hua<br />
<br />
==Dance party==<br />
<br />
Would anyone be interested in some sort of clubbing/dance party some time this month? And to be clear I don't mean going down to a bar to sit round drinking beers- that can be fun too, but I'm meaning something more music/dance focused. <br />
If so, <br />
<br />
What bars/clubs do people know of the might work? what music do they provide? <br />
<br />
What music are people interested in? Remember, music that is good to listen to is not always good for dancing (and to be fair, there's plenty of music which is fun to dance to, but might not actually be "good")<br />
<br />
Also, didn't someone mention some degree of DJing or music abilities? I can't remember, but if so, we could try to get our hands on the light rigs in the lecture hall and just make our own dance part from scratch...<br />
<br />
*Our own dance party from scratch sounds fun to me. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
So, some investigation indicates that hosting a large scale party at St Johns could be fairly impossible. She suggested hiring a venue in town... but I figure if that's the case we might as well just head down there and take it over by force of numbers.<br />
<br />
*There is a CSSS "Dance with Breadloaf workshop" scheduled for June 22 starting at 8:00 PM. Is this an actual dance, or is this a complexity science thing??? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
==Mountain Biking==<br />
<br />
I would like to go mountain biking on sunday (9th of June). Anybody interested in joining me? We can rent a bike in the city for either 30$ (hard tail) or 60$(fully), helmets are 4$ extra. For those who are interested: please put your name and your height (needed for bike reservation) here until Thursday evening, I'm going to reserve the bikes then. [[Johannes_Schmidt]]<br />
<br />
<br />
==Athletic Things==<br />
<br />
I've heard lots of people talking about running/walking etc, and at dinner last night we mentioned that it would be fun to have a running group. Anyone interested in having a running/walking group either in the mornings or evenings? Post interest here!<br />
<br />
I'm interested in a (quick) '''walking group''' in the mornings. It's great to exercise a bit in this nice weather and be able to talk at the same time. [[Regina_Martinez |Regina]]<br />
*I would also be up for quick walking - whether we mean walking briskly or walking for 20-30 min. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
<br />
Also, I love ultimate frisbee! Anyone interested in either learning or playing a game perhaps sunday or after dinner one day next week? Let me know! [[Brady_Stoll|Brady]]<br />
*Ultimate would be fun, although I had a pretty bad knee injury years ago and haven't done that much running since then. I could see how long I would last. --[[Vanessa_Schweizer | Vanessa]]<br />
*That's fine, anything would be fun, even just throwing/teaching people to throw! -Brady<br />
* Down to play. Anything planned for today? - Bapu<br />
* I don't have any specific plans today, but would love to either throw or teach if you're interested before the sun goes down. Play for sure tomorrow? Lets say tomorrow after dinner for those interested<br />
*'''Lets play frisbee today! (Wed) Meet after dinner and we'll walk over to the fields, or meet us there!'''<br />
<br />
Or basketball? Anybody want to play a pickup game?<br />
-I would play a pick up game -Brady<br />
<br />
==Yoga==<br />
<br />
Anyone interested in '''yoga tomorrow (Sunday 9th) at 7pm?''' Some of us are going to [[http://www.santafecommunityyoga.org/index.php/classes2/schedule]]. We are meeting at 6:30pm. There is only one more space in Lauren's car. But, if there are more people interested, we can try to find a solution for the commute. [[Regina_Martinez | Regina]]<br />
<br />
Hi Regina - I would be interested in joining you for yoga if there is still space. Please email me at [[jjwright49@me.com]] and let me know. Thanks! - [[Jody_Wright | Jody]]<br />
<br />
Anyone want to go to yoga tomorrow (Tuesday the 11th) evening? We were thinking of going to Hatha yoga at 5:30, so leaving campus at 5:00. We'll go to dinner afterwards too. Send me an email (lash1937@gmail.com) if interested. [[Lauren_Shoemaker | Lauren]]<br />
<br />
==Sightseeing Weekend==<br />
<br />
Anyone interested in going on a weekend road trip? This could be more of an 'easy going' option to the hiking trip proposed above. I was thinking of maybe driving up to Taos and doing some whitewater rafting and general sightseeing. Let me know if you are interested or have any other ideas. I don't have a car but am able to drive...<br />
<br />
- [[Ivana_Stankov | Ivana]]<br />
<br />
==THERE IS A FOURTH WEEKEND!!==<br />
<br />
If you, like me, believe that CSSS lives on after Saturday 29...<br />
<br />
If you, like me, are hanging around because you can't leave this sacred piece of ground anymore... <br />
<br />
If you, like me, believe this month is only the beginning of a life that wasn't before... <br />
<br />
<br />
Then you believe on the forth weekend!! I know many of you will stay a few days after CSSS is over and it would be nice to organize ourselves soon. So, if we choose to go somewhere, say taking a flight, we could get cheaper prices, etc! Also we will be needing shelter after the 29th. This might be an urgent thing ;) Let's use this to organize ourselves! I post some ideas below that I've heard around these days. -- [[Luís_Seoane | Luíño]]<br />
<br />
<br />
*Trip to the Gran Canyon? <br />
*Camping in some national park? <br />
*Trip to San Francisco? <br />
*Trip to Las Vegas where we make up random couples and get married :?<br />
<br />
I vote for Grand Canyon + San Francisco. I have my plane back home from Albuquerque on the 7th of July, so I am totally in for post school plans! -- Elisa<br />
<br />
If you come to San Francisco, I can probably show you some cool places. --[[Nix_Barnett | Nix]]<br />

As for Time/Place... Ummm... I feel like Thursday evening might be good, perhaps upstairs lower common room... but if other times/day/place suggested then that's good too.<br />

==Bandelier Field Trip==<br />
<br />
We're taking a trip to [http://www.nps.gov/band/index.htm Bandelier National Monument] on Saturday June 8th. Please visit the <b>[[Bandelier 2013 | Bandelier Field Trip]]</b> Page to sign up!<br />
<br />
==More Hiking!==<br />
<br />
Check the [[Complex Systems Summer School 2013-Hiking]] page to see current plans!<br />
<br />
<br />
Didn't get enough hiking at Bandelier? Come hiking/camping with me! I plan on going on a long hike (all day, preferably 10+ miles) one of the next two weekends. I brought things for camping and would love to do that if there is interest and it is possible to rent tents/sleeping bags in town (or if people want to just sleep outside, also fun). If that is not really possible or people would rather just go for a single day that is great as well. I am open to a lot of different things, there is so much great hiking around Santa Fe! <br />
<br />
Some suggestions:<br />
* [http://www.backpacker.com/april_1999_destinations_new_mexico_pecos_wilderness/destinations/696 Pecos Wilderness] - just outside of Santa Fe, lots of trails! <br />
* [http://www.summitpost.org/wheeler-peak-nm/150429 Wheeler Peak] - tallest mountain in New Mexico, outside of Taos (would require either camping at the base or waking up very early to do it the day of) <br />
** Near Taos we can find these [https://www.google.com/maps/preview#!data=!4m18!3m17!1m1!1sSanta+Fe+Institute%2C+1399+Hyde+Park+Road%2C+Santa+Fe%2C+New+Mexico!1m5!1sManby+Hot+Springs!2s0x87177428acfba0e5%3A0x69769a1d19abcbff!3m2!3d36.5083168!4d-105.7242545!3m8!1m3!1d10957!2d-105.7242545!3d36.5083162!3m2!1i1366!2i656!4f13.1&fid=0 hotsprings]!!!!!!! <br />
* [http://www.fodors.com/world/north-america/usa/new-mexico/taos/review-465844.html Carson National Forest] - North of Santa Fe, another beautiful forest, lots of different entrance locations <br />
<br />
I am up for any other suggestions if people have heard of trails they want to go on. Depending on how the fires progress we may or may not be limited, but should be able to do something! Send me an email if you are interested and we can talk logistics (bstoll1234@gmail.com) [[Brady_Stoll|Brady]]<br />
<br />
I would love to go! I had a hike in mind too--Tesuque Peak, which is just by the ski area and is 12 miles, but I am up for any of them! -Lauren (lash1937@gmail.com)<br />
<br />
I'm interested! -Hua (caih@umich.edu)<br />
<br />
I'm defintley interested - Wheeler Peak sounds very interesting (I have to get camping stuff though)! - johannes (johannes dot schmidt at boku dot ac dot at)<br />
<br />
If we did Wheeler Peak, I am highly in favor of the longer class 1 route. The shorter class 2 route has a scree slope at the end, and I really dislike scree (it scares me). If we camped at the trailhead, I have a 3 person tent that we could use. --Lauren<br />
<br />
If you'd like a similar experience to Wheeler Peak, but a lot closer, I recommend Santa Fe Baldy (12600'). Well above treeline, with fantastic vistas in all directions. The trailhead is only about 20 minutes away at the Santa Fe Ski Basin. The roundtrip hike is about 14 miles, making it a reasonable day hike. As always with any mountain around here, you need to be off the exposed sections by about 2PM because of the danger from thunderstorms! --John L<br />
<br />
More hiking would rock!(Although I'm not sure about optimal length...) --Todd<br />
<br />
==Music on the Hill==<br />
<br />
St. John's hosts [http://www.stjohnscollege.edu/events/SF/music.shtml live music] on the soccer field this Wednesday (June 12) as well as next Wednesday (June 19) and the Wednesday after (June 26). Performances start around 6:00 PM. It looks like all of the performers will be doing jazz. I really hope to make the June 19 performance, as this will be big band, which is (usually) great for dancing. Any other swing dancers in our group? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
* sounds fun to me! -- Hua<br />
* I'm definitely interested! --Molly<br />
* Sounds fun to me as welll! --Brady<br />
* Sounds fun! --Jody<br />
<br />
==Mafia/Werewolf==<br />
[[JP]] LOVES to Play [http://en.wikipedia.org/wiki/Mafia_(party_game) Mafia/Werewolf]. Let's set up a time one of these evenings in the lower commons...<br />
<br />
This sounds pretty cool. [[todd_bodnar | Todd]]<br />
<br />
I like Mafia a lot, and I also brought a card game called [http://en.wikipedia.org/wiki/Fluxx Fluxx], and also know a few other games you can play with just paper and pencil (like [http://natsdistractions.wordpress.com/2009/12/13/great-party-game/ Bucket of Nouns]). I think a game night would be fun! --Molly<br />
<br />
I would love to play Go if anyone is interested. --John D -- Count me in!! -- [[Luís_Seoane | Luíño]]<br />
<br />
We should probably set a time/day/place if we actually want this to happen... I suggest 7:00am on sunday, with the lower common room thing, unless something else is happening then.<br />
<br />
I like the game! Count me in! -- Hua<br />
<br />
==Dance party==<br />
<br />
Would anyone be interested in some sort of clubbing/dance party some time this month? And to be clear I don't mean going down to a bar to sit round drinking beers- that can be fun too, but I'm meaning something more music/dance focused. <br />
If so, <br />
<br />
What bars/clubs do people know of the might work? what music do they provide? <br />
<br />
What music are people interested in? Remember, music that is good to listen to is not always good for dancing (and to be fair, there's plenty of music which is fun to dance to, but might not actually be "good")<br />
<br />
Also, didn't someone mention some degree of DJing or music abilities? I can't remember, but if so, we could try to get our hands on the light rigs in the lecture hall and just make our own dance part from scratch...<br />
<br />
*Our own dance party from scratch sounds fun to me. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
So, some investigation indicates that hosting a large scale party at St Johns could be fairly impossible. She suggested hiring a venue in town... but I figure if that's the case we might as well just head down there and take it over by force of numbers.<br />
<br />
*There is a CSSS "Dance with Breadloaf workshop" scheduled for June 22 starting at 8:00 PM. Is this an actual dance, or is this a complexity science thing??? --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
==Mountain Biking==<br />
<br />
I would like to go mountain biking on sunday (9th of June). Anybody interested in joining me? We can rent a bike in the city for either 30$ (hard tail) or 60$(fully), helmets are 4$ extra. For those who are interested: please put your name and your height (needed for bike reservation) here until Thursday evening, I'm going to reserve the bikes then. [[Johannes_Schmidt]]<br />
<br />
<br />
==Athletic Things==<br />
<br />
I've heard lots of people talking about running/walking etc, and at dinner last night we mentioned that it would be fun to have a running group. Anyone interested in having a running/walking group either in the mornings or evenings? Post interest here!<br />
<br />
I'm interested in a (quick) '''walking group''' in the mornings. It's great to exercise a bit in this nice weather and be able to talk at the same time. [[Regina_Martinez |Regina]]<br />
*I would also be up for quick walking - whether we mean walking briskly or walking for 20-30 min. --[[Vanessa_Schweizer | Vanessa]]<br />
<br />
<br />
Also, I love ultimate frisbee! Anyone interested in either learning or playing a game perhaps sunday or after dinner one day next week? Let me know! [[Brady_Stoll|Brady]]<br />
*Ultimate would be fun, although I had a pretty bad knee injury years ago and haven't done that much running since then. I could see how long I would last. --[[Vanessa_Schweizer | Vanessa]]<br />
*That's fine, anything would be fun, even just throwing/teaching people to throw! -Brady<br />
* Down to play. Anything planned for today? - Bapu<br />
* I don't have any specific plans today, but would love to either throw or teach if you're interested before the sun goes down. Play for sure tomorrow? Lets say tomorrow after dinner for those interested<br />
*'''Lets play frisbee today! (Wed) Meet after dinner and we'll walk over to the fields, or meet us there!'''<br />
<br />
Or basketball? Anybody want to play a pickup game?<br />
-I would play a pick up game -Brady<br />
<br />
==Yoga==<br />
<br />
Anyone interested in '''yoga tomorrow (Sunday 9th) at 7pm?''' Some of us are going to [[http://www.santafecommunityyoga.org/index.php/classes2/schedule]]. We are meeting at 6:30pm. There is only one more space in Lauren's car. But, if there are more people interested, we can try to find a solution for the commute. [[Regina_Martinez | Regina]]<br />
<br />
Hi Regina - I would be interested in joining you for yoga if there is still space. Please email me at [[jjwright49@me.com]] and let me know. Thanks! - [[Jody_Wright | Jody]]<br />
<br />
Anyone want to go to yoga tomorrow (Tuesday the 11th) evening? We were thinking of going to Hatha yoga at 5:30, so leaving campus at 5:00. We'll go to dinner afterwards too. Send me an email (lash1937@gmail.com) if interested. [[Lauren_Shoemaker | Lauren]]<br />
<br />
==Sightseeing Weekend==<br />
<br />
Anyone interested in going on a weekend road trip? This could be more of an 'easy going' option to the hiking trip proposed above. I was thinking of maybe driving up to Taos and doing some whitewater rafting and general sightseeing. Let me know if you are interested or have any other ideas. I don't have a car but am able to drive...<br />
<br />
- [[Ivana_Stankov | Ivana]]<br />
<br />
==THERE IS A FOURTH WEEKEND!!==<br />
<br />
If you, like me, believe that CSSS lives on after Saturday 29...<br />
<br />
If you, like me, are hanging around because you can't leave this sacred piece of ground anymore... <br />
<br />
If you, like me, believe this month is only the beginning of a life that wasn't before... <br />
<br />
<br />
Then you believe on the forth weekend!! I know many of you will stay a few days after CSSS is over and it would be nice to organize ourselves soon. So, if we choose to go somewhere, say taking a flight, we could get cheaper prices, etc! Also we will be needing shelter after the 29th. This might be an urgent thing ;) Let's use this to organize ourselves! I post some ideas below that I've heard around these days. -- [[Luís_Seoane | Luíño]]<br />
<br />
<br />
*Trip to the Gran Canyon? <br />
*Camping in some national park? <br />
*Trip to San Francisco? <br />
*Trip to Las Vegas where we make up random couples and get married :?<br />
<br />
I vote for Grand Canyon + San Francisco. I have my plane back home from Albuquerque on the 7th of July, so I am totally in for post school plans! -- Elisa<br />
<br />
If you come to San Francisco, I can probably show you some cool places. --[[Nix_Barnett | Nix]]<br />
<br />
<br />
==Indoor climbing/bouldering on saturday (22)==<br />
<br />
Me (Oskar), Jian and Swahi are visiting the local climbing gym tomorrow. If you wanna try bouldering and maybe some rope climbing, we are leaving from the cafeteria at 10.00 after breakfast. If you feel like coming, you can email me at oskarxvi at gmail dot com (or just show up). We will visit the market and grap some lunch in town afterwards. See you!<br />

CSSS participants come from a wide range of disciplines. Participants are encouraged to share their knowledge by organizing their own tutorials. <br />
<br />
Also, please post requests for tutorials here.<br />
<br />
This is not a Tutorial! I [[Pablo_Galindo]] had nowhere else to post it! Its an article pointing out 15 mistakes that could sink your academic careers!<br />
http://chronicle.com/article/Self-Sabotage-in-the-Academic/138875/<br />
<br />
<br />
'''Bayesian Modeling'''<br />
I'd love to attend tutorials on Bayesian Modeling. I will be happy if someone can give a series of tutorials on this topic. [[Reniel_Cabral | Ren]]<br />
<br />
I would also be interested in this! -Brady<br />
<br />
* I might be able to help with this, though likely in more of a discussion format, perhaps with some slides stolen from a colleague :) [[Nix_Barnett | Nix]]<br />
<br />
* Thanks [[Nix_Barnett | Nix]]! Sure, I would love to have those slides and read it. [[Reniel_Cabral | Ren]]<br />
<br />
<br />
<br />
'''Dynamics in Networks'''<br />
<br />
I am very interested in learning about network dynamics. Anyone else interested in having a tutorial on that? [[Regina_Martinez | Regina]]<br />
<br />
* I'm very experienced with hidden Markov models, which are a generalization of Markov chains. These are networks with a (potentially stochastic) dynamic. Maybe this would help! [[Nix_Barnett | Nix]]<br />
<br />
<br />
'''Cross impact balances and Markov chains'''<br />
<br />
For anyone who could not make the tutorial, [https://docs.google.com/file/d/0B_w3ogGtuejzVG1Ma2tKenN2QjQ/edit?usp=sharing here is a copy of the slides], which provide another way of interpreting [http://www.cross-impact.de/english/CIB_e_Alg.htm web pages explaining the CIB algorithm]. Note that from the cross-impact balance analysis web site, you can download the free software to play with CIB analysis yourself. I am also happy to talk more one-on-one if needed! --[[User:Vanessas|Vanessas]] 02:24, 6 June 2013 (UTC)<br />
<br />
<br />
As part of brainstorming for a possible project, three of us have decided to do a tutorial on [http://arxiv.org/abs/0912.5352 cross-impact balances (CIB)] (delivered by [[Vanessa_Schweizer | Vanessa]]) and Markov chains (delivered by [[Alastair_Jamieson-lane | Alastair]] and [[Matteo_Smerlak | Matteo]]). We think these methods could be leveraged to research some interesting questions. All are invited to this tutorial regardless of their interest in contributing to a project using these methods. This tutorial will be Wed. June 5th at 4:00 PM in the large lecture hall. --[[Vanessa_Schweizer | Vanessa]] <br><br />
PS -- For those interested in examples of studies that have used CIB analysis, see this one on [http://iopscience.iop.org/1748-9326/7/4/044011/article century-long socioeconomic scenarios] or this abstract on a [http://link.springer.com/article/10.1007%2Fs10389-011-0473-8 qualitative model regarding obesity development and prevention].<br />
<br />
<br />
'''Python (and MASON)'''<br />
<br />
If anyone is interested, I'd be happy to organize and run/co-run a Python programming tutorial. If anyone needs agent-based models beyond what NetLogo can handle, I'd be happy to run a tutorial on the [http://cs.gmu.edu/~eclab/projects/mason/ MASON] framework. -- [[David_Masad]]<br />
<br />
Although I've been programming in python, this is the first time I've heard of MASON. I'm interested in learning about your framework. -- [[Cheryl_Abundo]]<br />
<br />
I'd very interest on such tutorials --[[Mauricio_Cantor]]<br />
<br />
I would also be interested in something on python -Brady<br />
<br />
<br />
'''Genetic Algorithms and Multi-Objective Optimization'''<br />
<br />
I have seen many people interested in implementing GAs to evolve networks, which is something I have done for some of my research. I also worked with Multi-Objective Optimization (MOO), which is perfectly possible with GAs and has been around for a while; but it has not become so mainstream. I propose to make a brief tutorial of <i>classic</i> Genetic Algorithm vs. Multi-Objective Genetic Algorithm. Enough people interested? If we are a few of us, we could just meet up and I'll tell you the basics! -- [[Luís_Seoane | Luíño]]<br />
I would be very interested! --[[Molly_King | Molly]]<br />
<br />
Me too --[[Mauricio_Cantor]]<br />

Me too --[[Elena_Stepanova | Elena]]<br />
<br />
Me too! --[[Matteo_Smerlak | Matteo]]<br />

'''Nix's Bag O' Mathematical Tools'''<br />
<br />
I'm planning on giving a number of tutorials to supplement Jim Crutchfield and I's lectures. The purpose of these should be to help you with your projects ( and encourage usage of our methods ;) ). I think it'd be cool for people to use this area to suggest topics to focus on. I started an empty bulleted list below. This will become more clear after we've given our lectures, but feel free to throw ideas out there when they come up. General topics might be: Information theory, time series analysis/modeling/prediction, symbolic dynamics (coarse-graining dynamical systems, i.e. what Liz Bradley discussed briefly), hidden Markov models, signal processing, bayesian inference, complexity measures, etc. [[Nix_Barnett | Nix]]<br />
*Intro to information theory. There seems to be some interest in this. I'd be happy to give a tutorial, but I should note that it will be covered (at a rapid pace) in Jim Crutchfield's lecture. [[Nix_Barnett | Nix]]<br />

==Project Proposals==<br />
<br />
=='''How the ocean can help us heal complex chronic disease'''==<br />
<br />
The human body is its own ecosystem -- much like the ocean -- with resilience, hysteresis, synergistic properties, and multi-system dynamics that depend on matrix conditions. We can use our understanding of the ocean and ecosystems to help us heal? Can we model different scales -- an ocean, a human body, and a microbial community -- to explore ecosystem/human/microbial health in a holistic context that depends on shared key elements like flow & trace minerals as building blocks for function? As one example to think about, chronic illnesses like HIV/AIDS or Lyme disease disrupt the immune system and human body functions (e.g., methylation pathways, detox pathways), preventing optimal function that weakens the human body and makes it vulnerable to other infections. It’s a downward spiral of negative feedbacks, analogous to a backed-up, atrophying ocean or estuary that causes fish kills, destroys coral reefs, etc... analogous to microbial communities that shift when environmental/matrix condition change. I suspect our knowledge of the ocean & large ecosystems, which we can see and visualize, can inform new thinking about system dynamics for health & recovery at the scale of a human body and at the scale of individual microbes & microbial communities...<br />
<br />
Anyone else interested? – [[Kristen_Honey | Kristen Honey]]<br />
<br />
- This sounds like a really nice idea. It would be interesting to understand how the disease-mediated degradation of immune/metabolic networks (the loss or alteration of edges and nodes?) affects the response of these networks to further perturbations (e.g. asymptotic stability and resilience, [http://www.jstor.org/stable/2266047 transient reactivity], cascading effects of node loss, etc.). I have little knowledge of the medical literature, but I am experienced in ecological network analysis including information theoretic analyses of weighted food webs. -- [[Ashkaan_Fahimipour | Ashkaan]]<br />
<br />

=='''Genetic algorithms to evaluate network formation or real-world data'''==<br />
I have an ill-defined, wacky idea to possibly use genetic algorithms to evaluate the formation of networks as either following preferential attachment or homophily (aka similarity) rules. This [http://www.nature.com/doifinder/10.1038/nature11459 short Nature paper] looks at the debate between preferential attachment and similarity/homophily dynamics. I don't have a clear idea of what this would look like, but I think it might be fun to think about ways to use genetic algorithms to solve network problems. Talk to me if you think this remotely interesting and we can evolve an idea together? --[[Molly_King | Molly]]<br />

Another possibility would be using genetic algorithms or attachment algorithms to compare to models of real-world data to understand how these networks likely formed and predict future edges.<br />

=='''Caribou Management Dynamics'''==<br />
<br />
This project would model caribou management dynamics in a prototype NW Alaska community during a caribou shortage. Agents in the model would be informed by data from household subsistence surveys and from management history. The goal would be to evaluate the abilities of different management strategies to achieve biological harvest goals while maximizing economic efficiencies in the community. This is a real-world problem with near-term applications. Caribou cycle on 30-to-50 year periods. The Western Arctic Caribou Herd is currently in decline. During the last caribou “crash” in this region, the state management system attempted to reorganize caribou production, which generated considerable political and social disruption, precipitated widespread passive resistance among Native peoples, and left a legacy of contempt for both management (among some Inuit) and for Inuit hunters (among some sport users). The hope is to reduce conflicts during the expected nadir of the population. Comments and cooperators welcome! [[James Magdanz | Jim]]<br />

=='''Evolving synchronized flashes in fireflies'''==<br />
<br />
[[Bryn_Gaertner | I ]] was thinking about how some, but not all, species of fireflies can synchronize their flashes, as was mentioned in both lectures today (June 4). The mechanism is fairly simple, it seems, so we should be able to evolve it using a simple genetic algorithm, right? This is only half-baked at the moment, and I haven't checked to see if it has been done already, but I thought it would be neat to explore the space around these biological phenomena.

=='''How do historic facts collapse into written history?'''==<br />
<br />
Let's begin with a nice example: [http://en.wikipedia.org/wiki/Gilgamesh Gilgamesh], the fifth king of Uruk, decided to gather together some stories that local tribes and surrounding cultures had been telling for years, along with things that previous kings had done. This became the [http://en.wikipedia.org/wiki/Epic_of_Gilgamesh Epic of Gilgamesh]. Someone later does a cover of the original book with some new contributions and turns it into what nowadays is the bible and the torah. Another remake of the tale turns these books into the quran, and until today... you know the rest of the story already. Peer reviewed quality, just like Nature or PNAS. <br />
<br />
It might be interesting to study how history goes from facts to a written, definitive form which is not (and maybe cannot be) completely faithfully to the actual events. There is huge room to use, for example, models of agents that contribute to form a History with pieces of information that sums up, sometimes with contradicting versions, sometimes with hidden interests, etc etc. Furthermore, we have a great tool in the wikipedia!! We can track, for example, how many changes are made on different entries over time. We can check whether there are some generalities, how the number of edits depends on the time gone after the historic event, maybe we can quantify how successive stories differ from each other and whether there are turning points that dramatically change the whole thing... <br />
<br />

<br />
=='''Meta Food Webs'''==<br />
<br />
I'd like to throw out an idea I've had for a while: Most animals use space in very important ways -- predators encounter and consume prey in both 2D and 3D environments, birds and fish migrate across continents in search of resources and mates, and plant pollinators fly or walk from flower to flower, in turn providing an indispensable economic service to humans. The study of food webs attempts to understand how networks of species that eat each other persist in the face of (sometimes constant) external perturbations. Yet, network-level food web studies seldom address the dynamics of animal movement, and I see this as a fundamental shortcoming in our understanding of nature. Recently, scientists in fields like computer science, physics and neurobiology have begun to model and explore [http://www.nature.com/srep/2012/120831/srep00620/full/srep00620.html?WT.ec_id=SREP-20120904 multi-level or multiplex networks] -- networks of nested networks. This seems like a reasonable candidate for the theoretical study of multiple food webs that are linked by spatial networks of animal movement. One preliminary question that comes to mind: How do the number of "mobile" species and the "speed of movement" alter important dynamical properties of complex food webs at larger spatial scales (i.e. at the meta-food web scale)? I am not dead set on answering this question, and I look forward to gaining insight from scientists who study other types of networks. I'm also not set on the multiplex network framework. Potential alternatives that come to mind are IBMs, PDEs on graphs or integrodifference equations. I look forward to any suggestions or bright ideas! --[[Ashkaan_Fahimipour | Ashkaan]]<br />
<br />
=='''(Evolution of) Aging'''==<br />
Sorry that this one is a bit long. I'd like to brainstorm with anybody interested to see if there could be a viable project in the following direction.<br />
<br />
Let me first define aging: deterioration that happens as an organism, e.g. a human being, gets physiologically older, eventually leading to increased mortality and/or decreased fecundity.<br />
<br />
Some background into the 'classic' theory: Evolution is about getting to be there in the future, that is, you and/or related organisms, for instance offspring. Increased mortality and decreased fecundity as such are clearly unfavorable to getting to be there in the future. Then why could it evolve? Well, evolution tends to become less sensitive to anything happening to an organism as time progresses, because events that take place at some point in time can affect only events that are future to that event. All offspring that an organism already has at some point cannot be affected anymore, and this is a non-decreasing function of time. This can be formalized, and I'd be happy to write down the math if anybody wonders.<br />
<br />
It has, however, limited value to theorize too much about age-specific events, while in fact events at different ages are tied together in pathways of causality, dynamic change and so on; age per se is not a cause of anything, and changes at some age do not happen independent of changes at other ages. There are a number of sufficient arguments why the 'age-specific' picture does not capture this reality. I'm skipping these arguments for now, but ask if you are interested.<br />
<br />
We have two things that matter for the evolution of aging. 1. The declining sensitivity of fitness to age-specific changes (of some standardized magnitude). 2. The fact that there are constraints that make that what happens at age x is not independent from what happens at the ages in its neighborhood. Thus, the trick is to figure out what the constraints are - this is where complexity may come in - and to combine these with the effect on fitness that age-related change has. The effect on fitness may be solved analytically, but there are various reasons why computation may be preferable, specifically the not always realistic assumptions that are necessary to allow for analytical solutions.<br />
<br />
Mechanistically, people tend to think about aging in two ways. The first is that aging is caused by the accumulation of damage. If this damage were all repaired, aging would not occur. People then try to think of reasons why repair would be imperfect. The second way to think about it is as a gradual loss of robustness/control, sometimes in the context of reliability engineering (is anybody familiar with that?). Beautiful medical example: old people need more insulin to process a standardized dose of sugar, and their regulation shows more peaks, especially upward peaks, than that of young people, who tend to need less insulin to process the standardized dose of sugar. Of course, if you consider loss of control as a type of damage, the two are the same, but the distinction is perhaps helpful because the way people tend to think about damage is not in a dynamical way, but just as protein aggregates sitting in the brain, inhibiting the function, cartilage that looses its suspension, etcetera. Again of course, both may influence each other.<br />
<br />
Now toward a project proposal. If I think about how complexity may (in part) determine physiological constraints, I think of the following. Usually people tend to think of repair being limited by available energy. But to repair something, the body needs to have available somewhere the information necessary to restore the initial state, and use that information at the place where the damage has occurred to be able to repair. This is where I hypothesize complexity comes in. The necessity of different components of the body to interact may put constraints on repair other than just energetic, it is also a question of whether the energy can actually be used for the repair (flow through the system in the necessary way). That may require space, a certain chemical environment, hormonal setting etcetera that may be incompatible with the proper function of an organism. (Can you repair a car when it is driving?) Also in the 'control/robustness thinking', you have to get back to the original situation to avoid aging. Is that compatible with the best evolutionary outcome?<br />
<br />
These are just some ideas I'm throwing at you, as you see it's not perfectly fleshed out yet, which is good, because it should benefit from your perspective. So anybody interested, please let me know!<br />
<br />
Cheers,<br />

==Quantifying Synchrony in Dynamics Occuring on Networks==<br />
<br />
[http://arxiv.org/pdf/1110.2724v1.pdf Recent work] has focused on developing information theoretic measures for quantifying directed information transfer, with particular applications to social media. These metrics are motivated by the work being done in theoretical / computational neuroscience on the analysis of spike trains. To do this analysis, the behavior of users on a social media platform like Twitter are treated as point processes, where we only keep track of when a tweet occurs, and ignore its content. That is, we treat a user's behavior over time as 'spikes.' Despite the simplicity of the approach, it was found to be successful in identifying key actors within real social networks.<br />
<br />
I am interested in applying a similar methodology, but using a [http://arxiv.org/abs/q-bio/0609008 different measure] of synchrony motivated by computational mechanics. This method seeks to learn the hidden states that generate a user's behavior (very much in the flavor of a Hidden Markov Model, but with a few key twists), and then considers the mutual information between the state sequences of the two users.<br />
<br />
A first step for this project would be implementing the methodology proposed by Shalizi, et al., on the toy model proposed by Steeg, et al.<br />
<br />
If that is successful (and completed quickly), I have a data set (network connections and behavior) of fifteen thousand Twitter users collected over a three month period. We are interested in using this approach to identify dynamical communities (not only users who are connected, but users who behave in synchrony) within the social network. This takes us beyond typical structural community detection that has had great success in the past decade.<br />
<br />
These approaches should work with any sort of dynamics occurring on top of a network-type structure, so if you have a different system you would like to use as a test case, I would be very interested to hear about it!<br />

===A spin off?===<br />
<br />
Sorry for editing in your proposal, Dave, but I wanted to comment an idea I have been interested in for a time now. There is this great technique used in neuroscience to pin down the most effective time-course excitation that a neuron can get so that it fires. It basically averages the input a neuron had been getting before each of its spikes. You can find a thorough description in the very popular [http://www.amazon.com/Theoretical-Neuroscience-Computational-Mathematical-Modeling/dp/0262541858 Dayan & Abbott] book on neuroscience. Since you mention the abstraction from tweets to spikes, I would be very interesting in applying such neuro-inspired analysis to this social interactions. Neuroscience has got many more techniques, so I do not pose it as a closed matter. Just open for discussion, but seems like everybody is sleeping by now ;) -- [[Luís_Seoane | Luíño]]<br />

=='''Energy resources supply patterns from biological systems to humans'''==<br />
<br />
My idea is to start a brainstorming, it is nothing more than some disjoints thoughts!!! And many questions without an answer so far!! :-)<br />
<br />
I would like to investigate how biological systems obtain their energy requirements. Are there patterns or network structure that evolution has developed and that are efficient for animals/plants?<br />
Can we replicate these structures/networks/patterns in the way we (humans) obtain our energy? Can we learn something from the evolution of the energy provisioning of other species? Is that feasible?<br />
My primary idea (given my research bias) is to then apply the findings to the structure of the electrical system. Is the current centralized generation and long distance distribution something that appears in nature? Is there a more efficient way that emerged from evolution in biological context that we can use for future provisioning?<br />
<br />
We can apply this not only to electrical systems but more in general to the way we use our resources.<br />
<br />
<br />
Anyone interested with ideas, feedbacks, thoughts? – [[Giuliano_Andrea_Pagani | Andrea]]<br />
<br />
=='''Cellular morphogenesis'''==<br />
<br />
I am interested in genetic design, not as much the modifications of already existing plants and animals but rather the capabilities of from-the-ground-up design of completely new organisms. One of the most basic question when it comes to multicellular organisms is how they end up with their particular shape and how it is a product of cell growth, membrane adhesion, chemical signalling etc. I suggest a project where we explore what types of shapes can emerge in simple cell growth models and how the shape can be controlled by tuning the organisms genes, the interactions. When we have something running, one interesting continuation would be to apply genetic algorithms on the growth parameters and se what happens with the emerging shape if we for example assign high fitness to high surface area but low volume, high moment of inertia or maybe concentric shells of different cell types and see what types of shapes emerge when under influence of external forces. We can also compare our results with simple, real organisms and se if nature found similar solutions.<br />
<br />
There are different cellular models we could use, most reasonable would be a cellular potts model (B) or a vertex dynamic model (D) [http://ars.els-cdn.com/content/image/1-s2.0-S0070215309890042-gr4.jpg], depending on what type of details we want to include. I suggest we start out with 2D simulations.<br />
<br />
I also believe this project can steer into many different directions, so if you like parts of the premise and have ideas on other directions we could take this, say hi.<br />

=='''How big can a city be?'''==<br />
<br />
West et al. have discovered striking—and universal—patterns in the way cities scale with size (see [http://www.ted.com/talks/geoffrey_west_the_surprising_math_of_cities_and_corporations.html West's Ted talk], [http://www.nature.com/nature/journal/v467/n7318/abs/467912a.html short Nature paper], [http://www.pnas.org/content/104/17/7301.short longer PNAS paper]). Do these scaling laws allow us to predict how big a city can be?<br />
<br />
Here's a motivating analogy. The mass of an animal grows scales the cube of its size L, but the cross-sectional area of its leg bones scales only like the square of L. This implies that bigger animals must have bulkier leg bones in order to sustain their own weight. (Think of the legs of a mouse versus the legs of an elephant.) Since the bones can never get bigger than the animal itself, this immediately tells you that land animals cannot be arbitrarily large: they must have a maximum size. If you plug in the numbers and estimate this maximum size, you find a value consistent with the largest known dinosaurs. In fact, with similar reasonings—which were discovered by Galileo, by the way—you can easily find how tall trees can be, how high animals can jump, etc [http://galileo.phys.virginia.edu/classes/304/scaling.pdf].<br />
<br />
Now, to run a similar argument for cities, we should understand what constraints would limit their size (the equivalent of "the legs of an animal can never be larger than the animal itself"). These constraints may be technical, social—I'm not sure. (Crimes are perhaps an example. West et al. show that the number of crimes committed in a city grows faster than the number of inhabitants. Clearly then, at some point the likelihood to get shot the next day will get too high, and people will start leaving the city.) I wonder if the social scientists among us have any insight about such constraints, and whether we can actually come up with a prediction for the maximal size of a city based on them. – [[Matteo_Smerlak | Matteo]]</div>Smerlakhttps://wiki.santafe.edu/index.php?title=Complex_Systems_Summer_School_2013-Projects_%26_Working_Groups&diff=49131Complex Systems Summer School 2013-Projects & Working Groups2013-06-05T05:53:34Z<p>Smerlak: </p>

=='''How the ocean can help us heal complex chronic disease'''==<br />
<br />
The human body is its own ecosystem -- much like the ocean -- with resilience, hysteresis, synergistic properties, and multi-system dynamics that depend on matrix conditions. We can use our understanding of the ocean and ecosystems to help us heal? Can we model different scales -- an ocean, a human body, and a microbial community -- to explore ecosystem/human/microbial health in a holistic context that depends on shared key elements like flow & trace minerals as building blocks for function? As one example to think about, chronic illnesses like HIV/AIDS or Lyme disease disrupt the immune system and human body functions (e.g., methylation pathways, detox pathways), preventing optimal function that weakens the human body and makes it vulnerable to other infections. It’s a downward spiral of negative feedbacks, analogous to a backed-up, atrophying ocean or estuary that causes fish kills, destroys coral reefs, etc... analogous to microbial communities that shift when environmental/matrix condition change. I suspect our knowledge of the ocean & large ecosystems, which we can see and visualize, can inform new thinking about system dynamics for health & recovery at the scale of a human body and at the scale of individual microbes & microbial communities...<br />
<br />
Anyone else interested? – [[Kristen_Honey | Kristen Honey]]<br />
<br />
- This sounds like a really nice idea. It would be interesting to understand how the disease-mediated degradation of immune/metabolic networks (the loss or alteration of edges and nodes?) affects the response of these networks to further perturbations (e.g. asymptotic stability and resilience, [http://www.jstor.org/stable/2266047 transient reactivity], cascading effects of node loss, etc.).

=='''(Evolution of) Aging'''==<br />
Sorry that this one is a bit long. I'd like to brainstorm with anybody interested to see if there could be a viable project in the following direction.<br />
<br />
Let me first define aging: deterioration that happens as an organism, e.g. a human being, gets physiologically older, eventually leading to increased mortality and/or decreased fecundity.<br />
<br />
Some background into the 'classic' theory: Evolution is about getting to be there in the future, that is, you and/or related organisms, for instance offspring. Increased mortality and decreased fecundity as such are clearly unfavorable to getting to be there in the future. Then why could it evolve? Well, evolution tends to become less sensitive to anything happening to an organism as time progresses, because events that take place at some point in time can affect only events that are future to that event. All offspring that an organism already has at some point cannot be affected anymore, and this is a non-decreasing function of time. This can be formalized, and I'd be happy to write down the math if anybody wonders.<br />
<br />
It has, however, limited value to theorize too much about age-specific events, while in fact events at different ages are tied together in pathways of causality, dynamic change and so on; age per se is not a cause of anything, and changes at some age do not happen independent of changes at other ages. There are a number of sufficient arguments why the 'age-specific' picture does not capture this reality. I'm skipping these arguments for now, but ask if you are interested.<br />
<br />
We have two things that matter for the evolution of aging. 1. The declining sensitivity of fitness to age-specific changes (of some standardized magnitude). 2. The fact that there are constraints that make that what happens at age x is not independent from what happens at the ages in its neighborhood. Thus, the trick is to figure out what the constraints are - this is where complexity may come in - and to combine these with the effect on fitness that age-related change has. The effect on fitness may be solved analytically, but there are various reasons why computation may be preferable, specifically the not always realistic assumptions that are necessary to allow for analytical solutions.<br />
<br />
Mechanistically, people tend to think about aging in two ways. The first is that aging is caused by the accumulation of damage. If this damage were all repaired, aging would not occur. People then try to think of reasons why repair would be imperfect. The second way to think about it is as a gradual loss of robustness/control, sometimes in the context of reliability engineering (is anybody familiar with that?). Beautiful medical example: old people need more insulin to process a standardized dose of sugar, and their regulation shows more peaks, especially upward peaks, than that of young people, who tend to need less insulin to process the standardized dose of sugar. Of course, if you consider loss of control as a type of damage, the two are the same, but the distinction is perhaps helpful because the way people tend to think about damage is not in a dynamical way, but just as protein aggregates sitting in the brain, inhibiting the function, cartilage that looses its suspension, etcetera. Again of course, both may influence each other.<br />
<br />
Now toward a project proposal. If I think about how complexity may (in part) determine physiological constraints, I think of the following. Usually people tend to think of repair being limited by available energy. But to repair something, the body needs to have available somewhere the information necessary to restore the initial state, and use that information at the place where the damage has occurred to be able to repair. This is where I hypothesize complexity comes in. The necessity of different components of the body to interact may put constraints on repair other than just energetic, it is also a question of whether the energy can actually be used for the repair (flow through the system in the necessary way). That may require space, a certain chemical environment, hormonal setting etcetera that may be incompatible with the proper function of an organism. (Can you repair a car when it is driving?) Also in the 'control/robustness thinking', you have to get back to the original situation to avoid aging. Is that compatible with the best evolutionary outcome?<br />
<br />
These are just some ideas I'm throwing at you, as you see it's not perfectly fleshed out yet, which is good, because it should benefit from your perspective. So anybody interested, please let me know!<br />

==Quantifying Synchrony in Dynamics Occuring on Networks==<br />
<br />
[http://arxiv.org/pdf/1110.2724v1.pdf Recent work] has focused on developing information theoretic measures for quantifying directed information transfer, with particular applications to social media. These metrics are motivated by the work being done in theoretical / computational neuroscience on the analysis of spike trains. To do this analysis, the behavior of users on a social media platform like Twitter are treated as point processes, where we only keep track of when a tweet occurs, and ignore its content. That is, we treat a user's behavior over time as 'spikes.' Despite the simplicity of the approach, it was found to be successful in identifying key actors within real social networks.<br />
<br />
I am interested in applying a similar methodology, but using a [http://arxiv.org/abs/q-bio/0609008 different measure] of synchrony motivated by computational mechanics. This method seeks to learn the hidden states that generate a user's behavior (very much in the flavor of a Hidden Markov Model, but with a few key twists), and then considers the mutual information between the state sequences of the two users.<br />
<br />
A first step for this project would be implementing the methodology proposed by Shalizi, et al., on the toy model proposed by Steeg, et al.<br />
<br />
If that is successful (and completed quickly), I have a data set (network connections and behavior) of fifteen thousand Twitter users collected over a three month period. We are interested in using this approach to identify dynamical communities (not only users who are connected, but users who behave in synchrony) within the social network. This takes us beyond typical structural community detection that has had great success in the past decade.<br />
<br />
These approaches should work with any sort of dynamics occurring on top of a network-type structure, so if you have a different system you would like to use as a test case, I would be very interested to hear about it!<br />

<br />
Sorry for editing in your proposal, Dave, but I wanted to comment an idea I have been interested in for a time now. There is this great technique used in neuroscience to pin down the most effective time-course excitation that a neuron can get so that it fires. It basically averages the input a neuron had been getting before each of its spikes. You can find a thorough description in the very popular [http://www.amazon.com/Theoretical-Neuroscience-Computational-Mathematical-Modeling/dp/0262541858 Dayan & Abbott] book on neuroscience. Since you mention the abstraction from tweets to spikes, I would be very interesting in applying such neuro-inspired analysis to this social interactions.

=='''Energy resources supply patterns from biological systems to humans'''==<br />
<br />
My idea is to start a brainstorming, it is nothing more than some disjoints thoughts!!! And many questions without an answer so far!! :-)<br />
<br />
I would like to investigate how biological systems obtain their energy requirements. Are there patterns or network structure that evolution has developed and that are efficient for animals/plants?<br />
Can we replicate these structures/networks/patterns in the way we (humans) obtain our energy? Can we learn something from the evolution of the energy provisioning of other species? Is that feasible?<br />
My primary idea (given my research bias) is to then apply the findings to the structure of the electrical system. Is the current centralized generation and long distance distribution something that appears in nature? Is there a more efficient way that emerged from evolution in biological context that we can use for future provisioning?<br />
<br />
We can apply this not only to electrical systems but more in general to the way we use our resources.<br />

=='''Cellular morphogenesis'''==<br />
<br />
I am interested in genetic design, not as much the modifications of already existing plants and animals but rather the capabilities of from-the-ground-up design of completely new organisms. One of the most basic question when it comes to multicellular organisms is how they end up with their particular shape and how it is a product of cell growth, membrane adhesion, chemical signalling etc. I suggest a project where we explore what types of shapes can emerge in simple cell growth models and how the shape can be controlled by tuning the organisms genes, the interactions. When we have something running, one interesting continuation would be to apply genetic algorithms on the growth parameters and se what happens with the emerging shape if we for example assign high fitness to high surface area but low volume, high moment of inertia or maybe concentric shells of different cell types and see what types of shapes emerge when under influence of external forces. We can also compare our results with simple, real organisms and se if nature found similar solutions.<br />
<br />
There are different cellular models we could use, most reasonable would be a cellular potts model (B) or a vertex dynamic model (D) [http://ars.els-cdn.com/content/image/1-s2.0-S0070215309890042-gr4.jpg], depending on what type of details we want to include. I suggest we start out with 2D simulations.<br />
<br />
I also believe this project can steer into many different directions, so if you like parts of the premise and have ideas on other directions we could take this, say hi.<br />

=='''How big can a city be?'''==<br />
<br />
West et al. have discovered striking—and universal—patterns in the way cities scale with size (see [http://www.ted.com/talks/geoffrey_west_the_surprising_math_of_cities_and_corporations.html West's Ted talk], [http://www.nature.com/nature/journal/v467/n7318/abs/467912a.html short Nature paper], [http://www.pnas.org/content/104/17/7301.short longer PNAS paper]). Can these scaling laws let us predict whether cities have an in-built maximum size, and if so, what will the maximum city look like?<br />
<br />
Here's a motivating analogy. The mass of an animal grows scales the cube of its size L, but the cross-sectional area of its leg bones scales only like the square of L. This implies that bigger animals must have bulkier leg bones in order to sustain their own weight. (Think of the legs of a mouse versus the legs of an elephant.) Since the bones can never get bigger than the animal itself, this immediately tells you that land animals cannot be arbitrary large: they have a maximum size. If you plug in the numbers and estimate this maximum size, you find a value consistent with the largest dinosaurs. In fact, with similar reasonings—which were discovered by Galileo, by the way—you can easily find how tall trees can be, how high animals can jump, etc [http://galileo.phys.virginia.edu/classes/304/scaling.pdf].<br />
<br />
Now, to run a similar argument for cities, we should understand what constraints would limit their size (the equivalent of "the legs of an animal can never be larger than the animal itself"). These constraints may be technical, social—I'm not sure. (Crimes are perhaps an example. West et al. show that the number of crimes committed in a city grows faster than the number of inhabitants. Clearly then, at some point the likelihood to get shot the next day will get too high, and people will start leaving the city.) I wonder if the social scientists among us have any insight about such constraints, and whether we can actually come up with a prediction for the maximal size of a city based on them. – [[Matteo_Smerlak | Matteo]]</div>Smerlakhttps://wiki.santafe.edu/index.php?title=Complex_Systems_Summer_School_2013-Projects_%26_Working_Groups&diff=49130Complex Systems Summer School 2013-Projects & Working Groups2013-06-05T05:52:00Z<p>Smerlak: </p>

==Project Proposals==<br />
<br />
=='''How the ocean can help us heal complex chronic disease'''==<br />
<br />
The human body is its own ecosystem -- much like the ocean -- with resilience, hysteresis, synergistic properties, and multi-system dynamics that depend on matrix conditions. We can use our understanding of the ocean and ecosystems to help us heal? Can we model different scales -- an ocean, a human body, and a microbial community -- to explore ecosystem/human/microbial health in a holistic context that depends on shared key elements like flow & trace minerals as building blocks for function? As one example to think about, chronic illnesses like HIV/AIDS or Lyme disease disrupt the immune system and human body functions (e.g., methylation pathways, detox pathways), preventing optimal function that weakens the human body and makes it vulnerable to other infections. It’s a downward spiral of negative feedbacks, analogous to a backed-up, atrophying ocean or estuary that causes fish kills, destroys coral reefs, etc... analogous to microbial communities that shift when environmental/matrix condition change. I suspect our knowledge of the ocean & large ecosystems, which we can see and visualize, can inform new thinking about system dynamics for health & recovery at the scale of a human body and at the scale of individual microbes & microbial communities...<br />
<br />
Anyone else interested? – [[Kristen_Honey | Kristen Honey]]<br />
<br />
- This sounds like a really nice idea. It would be interesting to understand how the disease-mediated degradation of immune/metabolic networks (the loss or alteration of edges and nodes?) affects the response of these networks to further perturbations (e.g. asymptotic stability and resilience, [http://www.jstor.org/stable/2266047 transient reactivity], cascading effects of node loss, etc.). I have little knowledge of the medical literature, but I am experienced in ecological network analysis including information theoretic analyses of weighted food webs. -- [[Ashkaan_Fahimipour | Ashkaan]]<br />
<br />
<br />
- I liked the idea very much. In fact I am looking at similar issues related to management of ecosystems which display hysteresis and [http://arno.uvt.nl/show.cgi?fid=121389 regime shifts]. Here is some pertinet information related to [http://www.esajournals.org/doi/abs/10.1890/1051-0761%281999%29009%5B0751%3AMOEFLS%5D2.0.CO%3B2 shallow lakes] and its [http://ideas.repec.org/p/att/wimass/200026.html complex dynamics].

=='''GDELT'''==<br />
<br />
[[David_Masad | I'd]] love to play around with the new [http://gdelt.utdallas.edu/ Global Data on Events, Location and Tone (GDELT)] dataset, which has 200+ million timestamped and geocoded political events. Here's a [http://ideas.foreignpolicy.com/posts/2013/04/10/what_can_we_learn_from_the_last_200_million_things_that_happened_in_the_world writeup of it in Foreign Policy] -- David<br />

=='''Research Network Formation'''==<br />
<br />
I'd be interested in collecting some data from CSSS attendants. Some kind of way to study social network formation. -- [[Todd_Bodnar | Todd]]<br />
<br />
Perhaps we could collect survey questions people might be interested in looking at in a [https://docs.google.com/document/d/1h_8TUyuDNT1DhPIyZuGwuvrqSExLgwoocsKZl4jFSk8/edit?usp=sharing Google Doc]? --[[Molly_King | Molly]]<br />
<br />
My new crazy idea, inspired by [http://blog.premise.is/blog/2013/5/5/mapping-the-produce-manifold these guys], is doing something with computer vision. Maybe there's a way to photograph sitting arrangements and extract data from that? -- David<br />
<br />
=='''Self-consistent networks for socio-economic institutions'''==<br />
<br />
[[Pablo_Galindo | Pablo]] and [[Vanessa_Schweizer | I]] started to discuss a project where we could use [http://arxiv.org/abs/0912.5352 cross-impact balances (CIB)] to investigate the implications of alternative hypotheses for interrelationships between various socio-economic/political factors. We began discussing this from the perspective of testing competing political economic theories to see what types of institutions (e.g. styles and stability of governance) would be self-consistent according to the theories. However, I would be open to other topics, including research questions inspired by GDELT. If there is interest to learn more about the CIB technique, I could put together a tutorial. --Vanessa<br />
<br />
<br />
=='''Genetic algorithms to evaluate network formation or real-world data'''==<br />
I have an ill-defined, wacky idea to possibly use genetic algorithms to evaluate the formation of networks as either following preferential attachment or homophily (aka similarity) rules. This [http://www.nature.com/doifinder/10.1038/nature11459 short Nature paper] looks at the debate between preferential attachment and similarity/homophily dynamics. I don't have a clear idea of what this would look like, but I think it might be fun to think about ways to use genetic algorithms to solve network problems. Talk to me if you think this remotely interesting and we can evolve an idea together? --[[Molly_King | Molly]]<br />
<br />
Another possibility would be using genetic algorithms or attachment algorithms to compare to models of real-world data to understand how these networks likely formed and predict future edges.<br />
<br />
<br />
=='''Caribou Management Dynamics'''==<br />
<br />
This project would model caribou management dynamics in a prototype NW Alaska community during a caribou shortage. Agents in the model would be informed by data from household subsistence surveys and from management history. The goal would be to evaluate the abilities of different management strategies to achieve biological harvest goals while maximizing economic efficiencies in the community. This is a real-world problem with near-term applications. Caribou cycle on 30-to-50 year periods. The Western Arctic Caribou Herd is currently in decline. During the last caribou “crash” in this region, the state management system attempted to reorganize caribou production, which generated considerable political and social disruption, precipitated widespread passive resistance among Native peoples, and left a legacy of contempt for both management (among some Inuit) and for Inuit hunters (among some sport users). The hope is to reduce conflicts during the expected nadir of the population. Comments and cooperators welcome! [[James Magdanz | Jim]]<br />
<br />
=='''Evolving synchronized flashes in fireflies'''==<br />
<br />
[[Bryn_Gaertner | I ]] was thinking about how some, but not all, species of fireflies can synchronize their flashes, as was mentioned in both lectures today (June 4). The mechanism is fairly simple, it seems, so we should be able to evolve it using a simple genetic algorithm, right? This is only half-baked at the moment, and I haven't checked to see if it has been done already, but I thought it would be neat to explore the space around these biological phenomena. More of a fun project than a serious "lets publish this!" type of project. Bonus points if we can work some neural network stuff into it. [[Bryn_Gaertner]]<br />
<br />
=='''How do historic facts collapse into written history?'''==<br />
<br />
Let's begin with a nice example: [http://en.wikipedia.org/wiki/Gilgamesh Gilgamesh], the fifth king of Uruk, decided to gather together some stories that local tribes and surrounding cultures had been telling for years, along with things that previous kings had done. This became the [http://en.wikipedia.org/wiki/Epic_of_Gilgamesh Epic of Gilgamesh]. Someone later does a cover of the original book with some new contributions and turns it into what nowadays is the bible and the torah. Another remake of the tale turns these books into the quran, and until today... you know the rest of the story already. Peer reviewed quality, just like Nature or PNAS. <br />
<br />
It might be interesting to study how history goes from facts to a written, definitive form which is not (and maybe cannot be) completely faithfully to the actual events. There is huge room to use, for example, models of agents that contribute to form a History with pieces of information that sums up, sometimes with contradicting versions, sometimes with hidden interests, etc etc. Furthermore, we have a great tool in the wikipedia!! We can track, for example, how many changes are made on different entries over time. We can check whether there are some generalities, how the number of edits depends on the time gone after the historic event, maybe we can quantify how successive stories differ from each other and whether there are turning points that dramatically change the whole thing... <br />
<br />
So this is the general framework. I think this is a very exciting topic and I'd be glad to talk about this with anyone!! Just contact me! -- [[Luís_Seoane | Luíño]]<br />
<br />
=='''Meta Food Webs'''==<br />
<br />
I'd like to throw out an idea I've had for a while: Most animals use space in very important ways -- predators encounter and consume prey in both 2D and 3D environments, birds and fish migrate across continents in search of resources and mates, and plant pollinators fly or walk from flower to flower, in turn providing an indispensable economic service to humans. The study of food webs attempts to understand how networks of species that eat each other persist in the face of (sometimes constant) external perturbations. Yet, network-level food web studies seldom address the dynamics of animal movement, and I see this as a fundamental shortcoming in our understanding of nature. Recently, scientists in fields like computer science, physics and neurobiology have begun to model and explore [http://www.nature.com/srep/2012/120831/srep00620/full/srep00620.html?WT.ec_id=SREP-20120904 multi-level or multiplex networks] -- networks of nested networks. This seems like a reasonable candidate for the theoretical study of multiple food webs that are linked by spatial networks of animal movement. One preliminary question that comes to mind: How do the number of "mobile" species and the "speed of movement" alter important dynamical properties of complex food webs at larger spatial scales (i.e. at the meta-food web scale)? I am not dead set on answering this question, and I look forward to gaining insight from scientists who study other types of networks. I'm also not set on the multiplex network framework.

I am interested in genetic design, not as much the modifications of already existing plants and animals but rather the capabilities of from-the-ground-up design of completely new organisms. One of the most basic question when it comes to multicellular organisms is how they end up with their particular shape and how it is a product of cell growth, membrane adhesion, chemical signalling etc. I suggest a project where we explore what types of shapes can emerge in simple cell growth models and how the shape can be controlled by tuning the organisms genes, the interactions. When we have something running, one interesting continuation would be to apply genetic algorithms on the growth parameters and se what happens with the emerging shape if we for example assign high fitness to high surface area but low volume, high moment of inertia or maybe concentric shells of different cell types and see what types of shapes emerge when under influence of external forces. We can also compare our results with simple, real organisms and se if nature found similar solutions.<br />
<br />
There are different cellular models we could use, most reasonable would be a cellular potts model (B) or a vertex dynamic model (D) [http://ars.els-cdn.com/content/image/1-s2.0-S0070215309890042-gr4.jpg], depending on what type of details we want to include. I suggest we start out with 2D simulations.<br />
<br />
I also believe this project can steer into many different directions, so if you like parts of the premise and have ideas on other directions we could take this, say hi.<br />

=='''How big can a city be?'''==<br />
<br />
West et al. have discovered striking—and universal—patterns in the way cities scale with size (see [http://www.ted.com/talks/geoffrey_west_the_surprising_math_of_cities_and_corporations.html West's Ted talk, science paper ], [http://www.nature.com/nature/journal/v467/n7318/abs/467912a.html short Nature paper], [http://www.pnas.org/content/104/17/7301.short longer PNAS paper]). Can these scaling laws let us predict whether cities have an in-built maximum size, and if so, what will the maximum city look like?<br />
<br />
Here's a motivating analogy. The mass of an animal grows scales the cube of its size L, but the cross-sectional area of its leg bones scales only like the square of L. This implies that bigger animals must have bulkier leg bones in order to sustain their own weight. (Think of the legs of a mouse versus the legs of an elephant.) Since the bones can never get bigger than the animal itself, this immediately tells you that land animals cannot be arbitrary large: they have a maximum size. If you plug in the numbers and estimate this maximum size, you find a value consistent with the largest dinosaurs. In fact, with similar reasonings—which were discovered by Galileo, by the way—you can easily find how tall trees can be, how high animals can jump, etc [http://galileo.phys.virginia.edu/classes/304/scaling.pdf].<br />
<br />
Now, to run a similar argument for cities, we should understand what constraints would limit their size (the equivalent of "the legs of an animal can never be larger than the animal itself"). These constraints may be technical, social—I'm not sure. (Crimes are perhaps an example. West et al. show that the number of crimes committed in a city grows faster than the number of inhabitants. Clearly then, at some point the likelihood to get shot the next day will get too high, and people will start leaving the city.) I wonder if the social scientists among us have any insight about such constraints, and whether we can actually come up with a prediction for the maximal size of a city based on them. – [[Matteo_Smerlak | Matteo]]</div>Smerlakhttps://wiki.santafe.edu/index.php?title=Complex_Systems_Summer_School_2013-Projects_%26_Working_Groups&diff=49129Complex Systems Summer School 2013-Projects & Working Groups2013-06-05T05:51:31Z<p>Smerlak: </p>

==Project Proposals==<br />
<br />
=='''How the ocean can help us heal complex chronic disease'''==<br />
<br />
The human body is its own ecosystem -- much like the ocean -- with resilience, hysteresis, synergistic properties, and multi-system dynamics that depend on matrix conditions. We can use our understanding of the ocean and ecosystems to help us heal? Can we model different scales -- an ocean, a human body, and a microbial community -- to explore ecosystem/human/microbial health in a holistic context that depends on shared key elements like flow & trace minerals as building blocks for function? As one example to think about, chronic illnesses like HIV/AIDS or Lyme disease disrupt the immune system and human body functions (e.g., methylation pathways, detox pathways), preventing optimal function that weakens the human body and makes it vulnerable to other infections. It’s a downward spiral of negative feedbacks, analogous to a backed-up, atrophying ocean or estuary that causes fish kills, destroys coral reefs, etc... analogous to microbial communities that shift when environmental/matrix condition change. I suspect our knowledge of the ocean & large ecosystems, which we can see and visualize, can inform new thinking about system dynamics for health & recovery at the scale of a human body and at the scale of individual microbes & microbial communities...<br />
<br />
Anyone else interested? – [[Kristen_Honey | Kristen Honey]]<br />
<br />
- This sounds like a really nice idea. It would be interesting to understand how the disease-mediated degradation of immune/metabolic networks (the loss or alteration of edges and nodes?) affects the response of these networks to further perturbations (e.g. asymptotic stability and resilience, [http://www.jstor.org/stable/2266047 transient reactivity], cascading effects of node loss, etc.). I have little knowledge of the medical literature, but I am experienced in ecological network analysis including information theoretic analyses of weighted food webs. -- [[Ashkaan_Fahimipour | Ashkaan]]<br />
<br />
<br />
- I liked the idea very much. In fact I am looking at similar issues related to management of ecosystems which display hysteresis and [http://arno.uvt.nl/show.cgi?fid=121389 regime shifts]. Here is some pertinet information related to [http://www.esajournals.org/doi/abs/10.1890/1051-0761%281999%29009%5B0751%3AMOEFLS%5D2.0.CO%3B2 shallow lakes] and its [http://ideas.repec.org/p/att/wimass/200026.html complex dynamics].

=='''GDELT'''==<br />
<br />
[[David_Masad | I'd]] love to play around with the new [http://gdelt.utdallas.edu/ Global Data on Events, Location and Tone (GDELT)] dataset, which has 200+ million timestamped and geocoded political events. Here's a [http://ideas.foreignpolicy.com/posts/2013/04/10/what_can_we_learn_from_the_last_200_million_things_that_happened_in_the_world writeup of it in Foreign Policy] -- David<br />
<br />
=='''Research Network Formation'''==<br />
<br />
I'd be interested in collecting some data from CSSS attendants. Some kind of way to study social network formation. -- [[Todd_Bodnar | Todd]]<br />
<br />
Perhaps we could collect survey questions people might be interested in looking at in a [https://docs.google.com/document/d/1h_8TUyuDNT1DhPIyZuGwuvrqSExLgwoocsKZl4jFSk8/edit?usp=sharing Google Doc]? --[[Molly_King | Molly]]<br />
<br />
My new crazy idea, inspired by [http://blog.premise.is/blog/2013/5/5/mapping-the-produce-manifold these guys], is doing something with computer vision. Maybe there's a way to photograph sitting arrangements and extract data from that? -- David<br />
<br />
=='''Self-consistent networks for socio-economic institutions'''==<br />
<br />
[[Pablo_Galindo | Pablo]] and [[Vanessa_Schweizer | I]] started to discuss a project where we could use [http://arxiv.org/abs/0912.5352 cross-impact balances (CIB)] to investigate the implications of alternative hypotheses for interrelationships between various socio-economic/political factors. We began discussing this from the perspective of testing competing political economic theories to see what types of institutions (e.g. styles and stability of governance) would be self-consistent according to the theories. However, I would be open to other topics, including research questions inspired by GDELT. If there is interest to learn more about the CIB technique, I could put together a tutorial. --Vanessa<br />
<br />
<br />
=='''Genetic algorithms to evaluate network formation or real-world data'''==<br />
I have an ill-defined, wacky idea to possibly use genetic algorithms to evaluate the formation of networks as either following preferential attachment or homophily (aka similarity) rules. This [http://www.nature.com/doifinder/10.1038/nature11459 short Nature paper] looks at the debate between preferential attachment and similarity/homophily dynamics. I don't have a clear idea of what this would look like, but I think it might be fun to think about ways to use genetic algorithms to solve network problems. Talk to me if you think this remotely interesting and we can evolve an idea together? --[[Molly_King | Molly]]<br />
<br />
Another possibility would be using genetic algorithms or attachment algorithms to compare to models of real-world data to understand how these networks likely formed and predict future edges.<br />
<br />
<br />
=='''Caribou Management Dynamics'''==<br />
<br />
This project would model caribou management dynamics in a prototype NW Alaska community during a caribou shortage. Agents in the model would be informed by data from household subsistence surveys and from management history. The goal would be to evaluate the abilities of different management strategies to achieve biological harvest goals while maximizing economic efficiencies in the community. This is a real-world problem with near-term applications. Caribou cycle on 30-to-50 year periods. The Western Arctic Caribou Herd is currently in decline. During the last caribou “crash” in this region, the state management system attempted to reorganize caribou production, which generated considerable political and social disruption, precipitated widespread passive resistance among Native peoples, and left a legacy of contempt for both management (among some Inuit) and for Inuit hunters (among some sport users). The hope is to reduce conflicts during the expected nadir of the population. Comments and cooperators welcome! [[James Magdanz | Jim]]<br />
<br />
=='''Evolving synchronized flashes in fireflies'''==<br />
<br />
[[Bryn_Gaertner | I ]] was thinking about how some, but not all, species of fireflies can synchronize their flashes, as was mentioned in both lectures today (June 4). The mechanism is fairly simple, it seems, so we should be able to evolve it using a simple genetic algorithm, right? This is only half-baked at the moment, and I haven't checked to see if it has been done already, but I thought it would be neat to explore the space around these biological phenomena. More of a fun project than a serious "lets publish this!" type of project. Bonus points if we can work some neural network stuff into it. [[Bryn_Gaertner]]<br />
<br />
=='''How do historic facts collapse into written history?'''==<br />
<br />
Let's begin with a nice example: [http://en.wikipedia.org/wiki/Gilgamesh Gilgamesh], the fifth king of Uruk, decided to gather together some stories that local tribes and surrounding cultures had been telling for years, along with things that previous kings had done. This became the [http://en.wikipedia.org/wiki/Epic_of_Gilgamesh Epic of Gilgamesh]. Someone later does a cover of the original book with some new contributions and turns it into what nowadays is the bible and the torah. Another remake of the tale turns these books into the quran, and until today... you know the rest of the story already. Peer reviewed quality, just like Nature or PNAS. <br />
<br />
It might be interesting to study how history goes from facts to a written, definitive form which is not (and maybe cannot be) completely faithfully to the actual events. There is huge room to use, for example, models of agents that contribute to form a History with pieces of information that sums up, sometimes with contradicting versions, sometimes with hidden interests, etc etc. Furthermore, we have a great tool in the wikipedia!! We can track, for example, how many changes are made on different entries over time. We can check whether there are some generalities, how the number of edits depends on the time gone after the historic event, maybe we can quantify how successive stories differ from each other and whether there are turning points that dramatically change the whole thing... <br />
<br />
So this is the general framework. I think this is a very exciting topic and I'd be glad to talk about this with anyone!! Just contact me! -- [[Luís_Seoane | Luíño]]<br />
<br />
=='''Meta Food Webs'''==<br />
<br />
I'd like to throw out an idea I've had for a while: Most animals use space in very important ways -- predators encounter and consume prey in both 2D and 3D environments, birds and fish migrate across continents in search of resources and mates, and plant pollinators fly or walk from flower to flower, in turn providing an indispensable economic service to humans. The study of food webs attempts to understand how networks of species that eat each other persist in the face of (sometimes constant) external perturbations. Yet, network-level food web studies seldom address the dynamics of animal movement, and I see this as a fundamental shortcoming in our understanding of nature. Recently, scientists in fields like computer science, physics and neurobiology have begun to model and explore [http://www.nature.com/srep/2012/120831/srep00620/full/srep00620.html?WT.ec_id=SREP-20120904 multi-level or multiplex networks] -- networks of nested networks. This seems like a reasonable candidate for the theoretical study of multiple food webs that are linked by spatial networks of animal movement. One preliminary question that comes to mind: How do the number of "mobile" species and the "speed of movement" alter important dynamical properties of complex food webs at larger spatial scales (i.e. at the meta-food web scale)? I am not dead set on answering this question, and I look forward to gaining insight from scientists who study other types of networks. I'm also not set on the multiplex network framework. Potential alternatives that come to mind are IBMs, PDEs on graphs or integrodifference equations. I look forward to any suggestions or bright ideas! --[[Ashkaan_Fahimipour | Ashkaan]]<br />
<br />
=='''(Evolution of) Aging'''==<br />
Sorry that this one is a bit long. I'd like to brainstorm with anybody interested to see if there could be a viable project in the following direction.<br />
<br />
Let me first define aging: deterioration that happens as an organism, e.g. a human being, gets physiologically older, eventually leading to increased mortality and/or decreased fecundity.<br />
<br />
Some background into the 'classic' theory: Evolution is about getting to be there in the future, that is, you and/or related organisms, for instance offspring. Increased mortality and decreased fecundity as such are clearly unfavorable to getting to be there in the future. Then why could it evolve? Well, evolution tends to become less sensitive to anything happening to an organism as time progresses, because events that take place at some point in time can affect only events that are future to that event. All offspring that an organism already has at some point cannot be affected anymore, and this is a non-decreasing function of time. This can be formalized, and I'd be happy to write down the math if anybody wonders.<br />
<br />
It has, however, limited value to theorize too much about age-specific events, while in fact events at different ages are tied together in pathways of causality, dynamic change and so on; age per se is not a cause of anything, and changes at some age do not happen independent of changes at other ages. There are a number of sufficient arguments why the 'age-specific' picture does not capture this reality. I'm skipping these arguments for now, but ask if you are interested.<br />
<br />
We have two things that matter for the evolution of aging. 1. The declining sensitivity of fitness to age-specific changes (of some standardized magnitude). 2. The fact that there are constraints that make that what happens at age x is not independent from what happens at the ages in its neighborhood. Thus, the trick is to figure out what the constraints are - this is where complexity may come in - and to combine these with the effect on fitness that age-related change has. The effect on fitness may be solved analytically, but there are various reasons why computation may be preferable, specifically the not always realistic assumptions that are necessary to allow for analytical solutions.<br />
<br />
Mechanistically, people tend to think about aging in two ways. The first is that aging is caused by the accumulation of damage. If this damage were all repaired, aging would not occur. People then try to think of reasons why repair would be imperfect. The second way to think about it is as a gradual loss of robustness/control, sometimes in the context of reliability engineering (is anybody familiar with that?). Beautiful medical example: old people need more insulin to process a standardized dose of sugar, and their regulation shows more peaks, especially upward peaks, than that of young people, who tend to need less insulin to process the standardized dose of sugar. Of course, if you consider loss of control as a type of damage, the two are the same, but the distinction is perhaps helpful because the way people tend to think about damage is not in a dynamical way, but just as protein aggregates sitting in the brain, inhibiting the function, cartilage that looses its suspension, etcetera. Again of course, both may influence each other.<br />
<br />
Now toward a project proposal. If I think about how complexity may (in part) determine physiological constraints, I think of the following. Usually people tend to think of repair being limited by available energy. But to repair something, the body needs to have available somewhere the information necessary to restore the initial state, and use that information at the place where the damage has occurred to be able to repair. This is where I hypothesize complexity comes in. The necessity of different components of the body to interact may put constraints on repair other than just energetic, it is also a question of whether the energy can actually be used for the repair (flow through the system in the necessary way). That may require space, a certain chemical environment, hormonal setting etcetera that may be incompatible with the proper function of an organism. (Can you repair a car when it is driving?) Also in the 'control/robustness thinking', you have to get back to the original situation to avoid aging. Is that compatible with the best evolutionary outcome?<br />
<br />
These are just some ideas I'm throwing at you, as you see it's not perfectly fleshed out yet, which is good, because it should benefit from your perspective. So anybody interested, please let me know!<br />
<br />
Cheers,<br />
Maarten<br />

==Quantifying Synchrony in Dynamics Occuring on Networks==<br />
<br />
[http://arxiv.org/pdf/1110.2724v1.pdf Recent work] has focused on developing information theoretic measures for quantifying directed information transfer, with particular applications to social media. These metrics are motivated by the work being done in theoretical / computational neuroscience on the analysis of spike trains. To do this analysis, the behavior of users on a social media platform like Twitter are treated as point processes, where we only keep track of when a tweet occurs, and ignore its content. That is, we treat a user's behavior over time as 'spikes.' Despite the simplicity of the approach, it was found to be successful in identifying key actors within real social networks.<br />
<br />
I am interested in applying a similar methodology, but using a [http://arxiv.org/abs/q-bio/0609008 different measure] of synchrony motivated by computational mechanics. This method seeks to learn the hidden states that generate a user's behavior (very much in the flavor of a Hidden Markov Model, but with a few key twists), and then considers the mutual information between the state sequences of the two users.<br />
<br />
A first step for this project would be implementing the methodology proposed by Shalizi, et al., on the toy model proposed by Steeg, et al.<br />
<br />
If that is successful (and completed quickly), I have a data set (network connections and behavior) of fifteen thousand Twitter users collected over a three month period. We are interested in using this approach to identify dynamical communities (not only users who are connected, but users who behave in synchrony) within the social network. This takes us beyond typical structural community detection that has had great success in the past decade.<br />
<br />
These approaches should work with any sort of dynamics occurring on top of a network-type structure, so if you have a different system you would like to use as a test case, I would be very interested to hear about it!<br />

===A spin off?===<br />
<br />
Sorry for editing in your proposal, Dave, but I wanted to comment an idea I have been interested in for a time now. There is this great technique used in neuroscience to pin down the most effective time-course excitation that a neuron can get so that it fires. It basically averages the input a neuron had been getting before each of its spikes. You can find a thorough description in the very popular [http://www.amazon.com/Theoretical-Neuroscience-Computational-Mathematical-Modeling/dp/0262541858 Dayan & Abbott] book on neuroscience. Since you mention the abstraction from tweets to spikes, I would be very interesting in applying such neuro-inspired analysis to this social interactions. Neuroscience has got many more techniques, so I do not pose it as a closed matter. Just open for discussion, but seems like everybody is sleeping by now ;) -- [[Luís_Seoane | Luíño]]<br />

=='''Energy resources supply patterns from biological systems to humans'''==<br />
<br />
My idea is to start a brainstorming, it is nothing more than some disjoints thoughts!!! And many questions without an answer so far!! :-)<br />
<br />
I would like to investigate how biological systems obtain their energy requirements. Are there patterns or network structure that evolution has developed and that are efficient for animals/plants?<br />
Can we replicate these structures/networks/patterns in the way we (humans) obtain our energy? Can we learn something from the evolution of the energy provisioning of other species? Is that feasible?<br />
My primary idea (given my research bias) is to then apply the findings to the structure of the electrical system. Is the current centralized generation and long distance distribution something that appears in nature? Is there a more efficient way that emerged from evolution in biological context that we can use for future provisioning?<br />
<br />
We can apply this not only to electrical systems but more in general to the way we use our resources.<br />

I'm a theoretical physicist, with interests ranging from general relativity to quantum mechanics and non-equilibrium statistical mechanics. I'd say the common theme in my research projects is "relativity"—the realization that something is actually much more observer-dependent that I had imagined.

<br />

- One interesting connection between physics and evolution I've come across is the "fluctuation theorem".

I've blogged about this on John Baez's "Azimuth" [http://johncarlosbaez.wordpress.com/2012/10/08/the-mathematical-origin-of-irreversibility/]. I'd love to know how you react to this surprising connection, and what outlook you see.<br />

- The result which really got me excited about complex systems is West's and Bettencourt's "scaling law of cities". As far as I can tell, it's really the first "law of cities". Does it tell us whether cities—like animals—have a maximal size?</div>Smerlakhttps://wiki.santafe.edu/index.php?title=Matteo_Smerlak&diff=48931Matteo Smerlak2013-06-04T15:48:57Z<p>Smerlak: </p>

I'm a theoretical physicist, with interests ranging from general relativity to quantum mechanics and non-equilibrium statistical mechanics. I'd say the common theme in my research projects is "relativity"—the realization that something is actually much more observer-dependent that I had imagined. I find this idea enormously beautiful, and tend to look for it everywhere. Did you know that your red T-shirt will be blue to me if I run into your arms? <br />

After graduating from Ecole normale supérieure de Lyon (France), I did my PhD in Centre de Physique Théorique de Luminy (France) under the supervision of Carlo Rovelli and Vincent Rivasseau. I am interested in theoretical physics in general (including quantum field theory and general relativity) and its applications to complex systems in particular.<br />
