Talk:Complex socio-ecological systems/Complex Adaptive Systems

SUMMARY DISCUSSION We did not concentrate on a particular paper but discussed concepts that were common to both. -Before diving into addressing the questions posted, we dealt with the issue of linearity vs. non-linearity. The concept of threshold was discussed, and refers to the case when the simple linear relationship between two variables is not sufficient to explain the novel configuration that a system can take. -Emphasis was made on the importance of feedback both within the CAS and between it and the surrounding environment. -The importance of history of the CAS (path dependency) was made. The evolutionary process has often been explained through the analogy of a random walk. Once a path is followed, the possibilities are different from those from a path taken on a different direction. Advancing through these “steps” determines (constrains) the possible configuration of CAS, but also provides novel opportunities for innovation and change (learning, adaptation). - There was some discussion about how could culture and tradition be considered, as if providing more or less resilience of social systems to change. We talked about mental models in the context of indigenous knowledge, and how adaptation could not be necessarily interpreted in a positive way (good vs. bad adaptation). - We discussed what were the differences between complex systems and complex adaptive systems, and some examples of the latter came out (global economic system). - We talked about basins of attraction and how the shape of these are determined by the diversity (variance) of potential configurations a system can take, and how they relate to resilience. The analogy was made with income sources for rural communities: the more they depend on a single resource (narrow basin of attraction) the more vulnerable they are to unexpected changes (surprises) of the CAS and the environment. -WE made emphasis on the existence of a transition zone between extreme systems’ configuration. This was discussed with the example of longleaf pine savannas and hammock forests in Florida. These two extremes represent stages where fire is following its natural regime (low intensity frequent fires) in long leaf pine savannas, to places where this disturbance has been removed. Yet, in nature we find a series of configurations along that gradient so it is important to remain flexible when trying to understand CAS. -The previous discussion was important when addressing the issue of a system being “at the edge of chaos”. Given that Levin and Lansing recognize the value of being in this stage as it provides the best opportunity for innovation and adaptation, it was important to try to bring back the issue that systems are not or frozen or chaotic, and there is a space between periodicity/stabiity and chaos that is important to consider. -It is important to keep the issue of scale in mind. Although we did not have enough time to address the five questions posted, it was interesting in the sense that we are all struggling to become more comfortable with the CAS ideas.

Hi! WE thought we would send some questions/issues/thoughts to think (even) further… to spark/guide some discussion tomorrow.

Issue 1. “Heavily managed systems, such as in agriculture or forestry, are not purely complex adaptive systems, in that their simplified structures are imposed exogenously rather than arising endogenously” (From Levin, 1999).

Anthropogenic is always exogenous? Why is this important when looking at CAS?

Issue 2. From Lansing paper there is the suggestion that closeness to the edge of chaos means more adaptation potential. What are the costs of being at the edge of chaos? Implications of this closeness?

Issue 3. Comment this statement…P. 189 (Lansing). “At the other extreme, when K is small, networks exhibit stable or periodic behavior”.

Issue 4. “…To what extent can the patterns of distribution of ecosystem properties be explained by under lying variation in physical variables, such as regional climate and soil conditions, and to what extent are they the result of self-organization”. (From Levin 1999). Having been exposed to all the talk about systems from last 2 weeks what would you say is missing from this statement?

Issue 5. “.. Aggregation and hierarchical assembly are not imposed on complex adaptive systems, but emerge from local interactions through endogenous pattern formation..” (From Levin 1999).. Any comments on this?

comments
Hi! Please remember to post comments today. One of us has not internet access after 5 pm.. Thanks! C&C Claudia 14:35, 20 January 2011 (UTC) - Lansing and Levin’s pieces compliment each other in surprising ways, and not merely because they both discuss CAS in evolutionary biology, but because they speak to the existence of emergent properties. This is the fundamental agreement I seem to find in all this literature, that scale is of the utmost importance in deciding when a system is linear or not (and most of the times it’s not). Amid all this discussion of basins, K states, and epistatic convergence, Lansing’s critique of CAS is more robust than Levin’s in that he takes a grand survey of the different fields where CAS has been applied. But it is Levin who is clearer in his delimiting of where CAS and sources of resilience (or the edge of chaos) can be found. Lansing infers that there is a separation between adaptive systems like cellular automata and complex, but arguably nonadaptive systems, like post-disaster landscapes. I guess this illustrates how dated or unenlightened my reading of complexity science has been, but I somehow assumed that complex systems and CAS were one in the same, that both took into account nonlinear processes, and that the social scientists had led much of the way alongside ecologists in nonequilibrium thinking. This is apparently not the case, at least according to Lansing and many of his peers, but one can’t help but pick recent editions of Ecology and Society and other journals that very much do speak of adaptation from both acute and chronic shocks and stressors, in ways that do not illustrate the kind of self-organization Lansing endorses. This literature hails itself as the work of adaptive science. Admittedly I’m waist deep in it so perhaps I need to step back and take a more critical eye in the same way Lansing might. The dissonance in his paper is a little bit troubling for me, though, just as the postulation that artificial intelligence has been biased towards the science fiction, when its real world applications (like the prisoner’s dilemma, or modeling of Bali rice fields) should better steer complexity science—aren’t both a reflection of Levin’s “anthropic principle” in some way (this goes back to last week’s discussion of models and how all of them are “wrong,” or at least biased in some form). I think this would be a great jumping off point for discussion on Friday if the format hasn’t already been decided upon. 68.105.165.243 15:59, 20 January 2011 (UTC) Sam

Lansing:

It was nice to read about how debate and research on complex adaptive systems evolved and the different concepts associated with this field of research. Some concepts were new to me, such as "basins" of attraction and "edge of chaos".

One element that caught my attention is the discussion regarding the fitness of an individual versus the the fitness of a network of connected individuals. What I understood here is that the more connected an individual is, the more it/he/she will depend on the other individuals to evolve: "the fitness of an organism or species depends upon the others which with it interacts" (p.186). However, Lansing also explained that the number of connections (K) affects the adaptive landscape, changing it from "Mount Fitness" to "tiny hills." Does this mean that the more organism are connected, the less adaptation is needed? This was a bit confusing to me. I get how more connections make it more difficult for any individual to evolve by itself, but I don't understand how connections affect the adaptive landscape.

The impact that the number of connections have on the behavior of the system, and its capacity to adapt: Based on the author's explanation of the Kauffman/Langton experiments, I understood that there is an ideal number of connections that allows information to be transmitted and the system to adapt. Few connections can result in a frozen system and too many connections can result in a chaotic system. The ideal state when thinking about adaptation is to have around 2 connections, which would make the system be at "the edge of chaos," a state that allows for adaptation and information transmission.

I find it somewhat difficult to grasp that complex systems are at the "edge of chaos," which is a good state because it allows for adaptation. The implication of this idea is that societies need to be at this state for it allows societies to adapt and get to "food sources of higher quality." Not being at the edge of chaos would mean that a society is in either a chaotic or a frozen/periodic state, which are worse states because they do not allow information flow and adaptation. The implication is that complexity (the edge of chaos) is good for societies, because it allows evolution.

Basins of attraction: How is the "basin of attraction" different than an equilibrium state? The idea that lights blink disorderly, but eventually go to the "state cycle or pattern of twinkling" tells me that systems tend to move to an equilibrium state.

The discussion about ENSO/Borneo forest talks about self-organization of systems and reminds me of ecosystem "equilibriums." However, there is a move away from the idea of equilibrium in nature, as exemplified by the author's "critique of equilibrium theory."

I find two ideas to be contradictory: 1) On one hand, repeated interactions between humans can lead to optimal outcomes, such as the Balinese irrigation systems. 2) On the other hand, humans can really mess up natural occurring self-organizing systems, like the policy makers in Borneo, who did not take into account the self-organization of the forest. Why interactions between humans and between humans and ecosystems led to a positive outcome in one case but not the other? Is it because in Borneo there were NOT repeated interactions (which are important for learning and collaboration)? Will the better outcome eventually come in Borneo, since now policymakers there know the negative feedback of their actions?

In blaming environmental problems on the excessive number of people in the world (as the author does when he agrees with Holland), the author seems to assume that humans are not part of self-organizing systems. The message seems to be: Humans, an exceptional species, mess up self-organizing systems. Doesn't the self-organizing principle applies to humans and human society?

Emergence of institutions: Author points out that institutions can emerge from the bottom-up as a result of local interactions. The image I got was of institutions popping-up unintendenly as a result of local interactions -- in an unplanned way. I believe the author did not meant to portray this imagine, but only that institutions can emerge from the bottom up as social actors learn from the feedbacks they receive. I guess the word "emergence" is the word that makes me think of "unintened" institutions.

While this is the case sometimes (bottom-up institutions), as the literature on the commons show, most  often institutions result from planned action to serve specific functions, such organizing people/processes in order to achieve specific outcomes, or as a means of social control. And institutions are often created top down, rather than allowed to "emerge". The Balinese case brings up the question of whether it would not be better for policy makers to allow institutions to emerge as a result of feedbacks and local action? This would mean allowing the learning and cooperation to occur. I know... I always bring these "should" questions. I guess I can't avoid thinking about policymaking. After all, aren't we learning about complex systems because we assume that by understanding systems and complexity we can make better decisions? flaleite 21:46, 20 January 2011 (UTC)

Sorry this is late, everybody- I spent the day in bed with food poisoning. Disclaimer: Hello, everyone! I suppose I'm posting as today's resident anthropologist, but you should by no means take me as a representative sample as a)I'm a graduate student, and b)I'm a product of my training, which is from an applied medical anthropology/biocultural/fairly materialist point of view. So my take on the readings, and thus my questions, come from that standpoint, and from an ongoing assessment of what is, and is not, useful to my own work.

Field-Specific Background: Just for some quick "History of Anthropology" background on the readings, the Whiting six-culture study mentioned in the Levin paper was a landmark paper in anthropology, and a comparative paper that created a whole new generation of scholars. John and Bea Whiting were students of John Dollard, who, along with Edvard Sapir, George Peter Murdock (from the Murdock "Standard Cross-Cultural Sample" also mentioned in the Levin paper)and Clark Hall, were part of the "Yale Synthesis", which, to my best guess, was simply a group of graduate students who got together and rejected the uber-relativist configurational school of culture and personality spearheaded by Margaret Mead, Ruth Benedict, and Franz Boas. To the best of my knowledge (and remember, I'm still a student) the Yale Synthesis was a theoretical perspective that rejected the idea that cultures could not be compared along material lines. One of the many brainchildren that came from this school was the HRAF, or Human Relations Area Files, created by George Peter Murdock (who went on to found the Department of Anthropology at the University of Pittsburgh), which was one of the first attempts made to quantify ethnographic data for purposes of comparison. The HRAF files have been critiqued heavily for many of the same issues that Levin mentioned as being problems with his dataset (Levin, pg.5-6); regional biases within the dataset, unequal training in/focus on demography among ethnographers, problems with sampling (including culture unit size and missing data), and a lack of systematized collection. Many of these problems, as far as I can see, are at least initially inescapable given the way that ethnographic work is currently executed. Many different ethnographers = many different goals and many different foci. It may be difficult or inadvisable to use an ethnographer's demographic data on child rearing practices when the ethnographer in question spent their field time focused on religion, and gave child-rearing and household ecology only the briefest of nods in their dissertation.

Questions for Myself and Others: However. Stating that there is difficulty in doing a thing is a far cry from saying that it cannot be done, and I feel there is danger, at least for applied fields, in assuming a point of view so relativistic as to not allow for any comparison between cultures whatsoever. This brings up what seems to be one of the core questions of our ongoing discussion; assuming complex systems can be modeled, can be compared in meaningful and useful ways, HOW is it to be done? Can we take steps- or better yet, should we take steps- in the very infancy of our research to make it more systematized and more palatable to comparative studies later on?

Also (and I'm trying to keep things basic, as class discussion so far had been fairly theoretical);

Can there be a happy marriage between ethnography and demography? How can the difference in traditional scales and modus operandi between the two fields be reconciled? Take, for example, the numerous methodological problems encountered in the Levin, 1991 dataset.

Given the differing goals of different ethnographic studies, is it good practice to use demographic data from multiple studies who may or may not have been interested in the same topics, and therefore lack any form of unified systematic data collection? (Think about the Pitt/Yale Human Relations Area Files (HRAF)). How can we get around this? Cbaird

Tectonic hazards/Earthquake engineering

Earthquake engineering is the study of the behavior of building structures subject to earthquake impacts.

Objectives of the earthquake engineering
The main objectives of earthquake engineering are:
 * Understand the interaction between buildings and the ground.
 * Foresee the potential consequences of strong earthquakes on building structures.
 * Design, construct and maintain structures to perform at earthquake exposure up to the expectations and in compliance with building codes.

Tools
A properly engineered structure does not necessarily have to be extremely strong or expensive.

The most powerful and budgetary tools of earthquake engineering are vibration control technologies and, in particular, base isolation.

To verify experimentally the earthquake or seismic performance of a building structure, it may be put on a shake-table that simulates the earth shaking. The earliest shake-table experiments were performed more than a century ago

Tsunami preparedness and protection
Tsunami or a chain of fast moving waves in the ocean caused, mostly, by powerful earthquakes is a very serious challenge for people's safety and for tsunami protection of buildings and civil infrastructure. Those waves can inundate coastal areas, destroy houses and even swipe away whole towns.

Though tsunami can not be prevented, there are Tsunami warning system developed recently which warn the population before the big waves reach the land to let them enough time to rush to safety.

You will need to assert the fair use. Use the following at the bottom of the image page.

I suggest the following, but you may have better information, it's up to you.

 * If your the inventor that is great but all media files to contain this information on page of the file. Just fill out a information template like so:

 * and create a license section and place an appropriate license template in the licensing section. The end result of the information displayed will be very similar to the link to commons that you've given above. Thenub314 21:02, 29 October 2011 (UTC)

It seems all the information requested by you is and has been presented in the File:Earthquake-Protective Building Buffer-exploded.png. Do I need to add anything more? Shustov 06:28, 30 October 2011 (UTC)
 * No nothing more, but you need to add that sort of information to each and every file uploaded to WV. Thenub314 03:18, 7 November 2011 (UTC)

I'll do my best. Shustov 09:06, 7 November 2011 (UTC)

 * Excellent, and I will do my best to help. I have no interest in deleting useful stuff, so if you need help getting these templates put up on the pages mentioned on your discussion page I would be glad to lend any assistance I can.  I would do it myself but I don't know which license you plan to release them under, who took the origina photo, etc. Thenub314 19:39, 7 November 2011 (UTC)

Thank you. Usually, I use the Creative Commons Attribution 3.0 Unported license for my contributed photos and gifs. Best! Shustov 21:36, 7 November 2011 (UTC)

What is the copyright of File:Fluid viscous damper.jpg?

 * You may remove the file. No big deal! Shustov 20:12, 29 October 2011 (UTC)
 * mmm.... the file is in use at Hysteretic damper. Are you sure, Shustov? Do you own the file? --Abd 22:27, 7 November 2011 (UTC)

Copyright of Wikimedia Foundation projects
Hi. :) I notice that you've been creating articles by copying content from corresponding subjects on Wikipedia. I need to make sure that you know that content on Wikimedia Foundation projects is not public domain. While you are welcome to reuse it on Wikiversity or other projects, you are required to give proper attribution. I don't know if Wikiversity has a page explaining how this is done, but Wikipedia does; w:Wikipedia:Copying with Wikipedia. Since the minimum attribution required is a hyperlink and edit histories must be retained for compliance with GFDL, you should put a statement in edit summary when you copy content saying something like "content taken from w:article title, which see for attribution". It may be safest to put a note on the talk page as well with a link to the source, but the note in the edit summary should be legally sufficient. Can you please provide attribution for content you've already copied? --Moonriddengirl 17:28, 29 November 2011 (UTC)

 * I, practically, always provide links to Wikipedia, Commonscat and Wiktionry. Exception is Simple English Wikipedia because I do not know the proper template for this. Besides, all my contributions to Wikiversity are based on my articles from the above projects I either created by myself or contributed to. Anyway, I will provide this Note on my talk page too. Thanks! Shustov 21:06, 29 November 2011 (UTC)

alternate accounts
I see that you are apparently editing here using alternate accounts names. Looking at your cross-wiki contributions, I see that you have been blocked on a number of wikis. We are not concerned with that, but the use of alternate accounts here, especially when you edit the Shustov user page, creates maintenance problems. We ordinarily do not allow users to edit the user page of other users.

The accounts I see are User:ShustovVal and User:Vshustov. I see that those users have redirected here, so that is disclosure from one end. Please acknowledge, here or on your user page (better), logged in as Shustov, that these are you. If you cannot do that for some reason, please explain.

Vshustov was also blocked on en.wikipedia, and it is completely obvious why, totally predictable, just from reading the user talk page there and knowing that Shustov is blocked.

Sometimes I'm able to assist users who run into trouble. If you would like to discuss that, you may respond here, or my email is open. Thanks, and thank you for your contributions to Wikiversity. --Abd (discuss • contribs) 14:29, 18 October 2014 (UTC)

 * I did not create the different accounts User:ShustovVal and User:Vshustov on purpose. It just happened because one of my computers (I had no idea why) responded to user name User:ShustovVal and another to User:Vshustov only. If you can help me to stay with my old name User:Shustov, it will be greate!ShustovVal (discuss • contribs) 19:11, 18 October 2014 (UTC)
 * Shustov, that makes no sense. What your computer responds to and what you enter in the login are different. If you want to use Shustov, log out and log in as Shustov! If you have lost the password, you should be able to reset it, you should be able to confirm this with email, assuming you still have access to the original email account. --Abd (discuss • contribs) 21:12, 18 October 2014 (UTC)

 * Thank you and sorry for delay. I did manage to log in as User:Shustov for my Wikiversity account at last. Let's hope for the best! Shustov (discuss • contribs) 07:54, 18 February 2015 (UTC)

 * Hi, mr. Shustov. We like your pictures and contributions. You can join Wikisage (it's Dutch/NL). You can write article's there (in dutch) and there is a local upload possibility. Kind regards, Nomen Nescio - 84.105.131.79 (discuss) 19:58, 17 February 2015 (UTC)

Hi, Nomen. Will you specify what your Wikisage means, please? Thanks! Shustov (discuss • contribs) 08:32, 18 February 2015 (UTC)

Your problems at Commons
I'm posting this here because you referred to some problems on Commons, so I looked at your user talk page there. You have had a lot of images deleted. However, what leaped out at me was this:. This was about behavior of a Wikipedia administrator. Very inappropriate to use your Commons User talk page to complain about Wikipedia problems. Sure enough, you were warned there, and then short-blocked. First discussion, closed with warning. Second discussion, closed with intensified warning, and you were finally blocked for one day, after insisting on pursuing your agenda. You actually continued, but not so blatantly enough that you were blocked again.

(Looking at the problems on Wikipedia, you were indefinitely blocked there, and are still blocked there, by that administrator. The admin had previously unblocked you, per an agreement. see.

Now, basic error. Arguing with an administrator. This is why Shustov is still blocked on Wikipedia. It doesn't matter if you are right or wrong. It is like arguing with a police order. It can get you tossed in jail, if you disregard the order. Even if you are right. With an administrator is not the place to argue! This would guarantee that no administrator would unblock you.

By the way, I have a fairly nasty history with that administrator, this is not about him. It is about what has led to your defacto ban from Wikipedia. You could be unblocked, but you would need to take some steps.

It would be a lot of work to go over your Commons history. I could probably explain why your images were deleted. Commons, however, follows copyright policy very strictly, and it can be difficult to understand. If you want me to look, I will. Otherwise, please do not complain about users on other wikis, on Wikversity. It's one of the few things that can get you in trouble here. Good luck. --Abd (discuss • contribs) 00:46, 20 February 2015 (UTC)

 * On a hunch, I also looked at User:ShustoVal on Commons. This is very recent, just three days ago. I highly recommend you immediately apologize. It can sometimes take days for the wiki community to respond. You are in danger there of having Shustov blocked, not just ShustoVal. Yes, you have had a problem with autoblock. It happens. I would think you could edit as Shustov now. If not, you would get a very specific message. You will need to copy that message exactly to resolve the problem.

 * You created a huge mess by using the other account. Then, with ShustovVal, you questioned every deletion notice on your talk page. Deletion discussions are not held that way, they are handled on the linked page. I've looked at a few discussions. You simply did not understand what was going on, but you were quite sure you were being treated unfairly. When a user comes to see things that way, it is predictable that they will be blocked. --Abd (discuss • contribs) 01:23, 20 February 2015 (UTC)

 * As an example of what I saw indicating lack of understanding, on the Talk page of your other sock, I saw you refer to a speedy deletion notice as "vandalism." That was placed by a user I happen to know. Young fellow. Used to be a probationary custodian here. Calling him a vandal isn't going to help. He did not vandalize anything. He saw a file that appeared to him to be copyright violation and he tagged it. He did not delete it. An administrator did. Slow down, Shustov, you are making mistake after mistake, and the other wikis are not like Wikiversity. Here, your education, your learning-by-doing, is part of our mission. So, usually, we will explain things, you can make mistakes and we will help you fix them, and so forth. On the other wikis, sometimes you may get this help and sometimes not. And when you start calling users "vandals" and complaining about how what they are doing is "ludicrous," and so on, you will *not* get help, and certainly not from them!

 * If a file is speedy deleted there, it is possible it could be quickly undeleted, but you would need to follow process, not just complain on your user talk page, that will do *nothing.* And complaining about the misbehavior of others is never a way to get it done. Few, if any, are reading your user talk page! However, when you have accumulated many file deletion notices, those who placed them may have your user page on their Watchlist, so *they* will see, and if you have insulted them, they then focus on what is wrong with your work. What would you expect? I already see a sign that this has been happening. --Abd (discuss • contribs) 01:35, 20 February 2015 (UTC)

 * I highly appreciate your above comments and will do my best to behave accurately. My best! Shustov (discuss • contribs) 09:44, 20 February 2015 (UTC)

 * It's likely to take some training and education. Are you up for it? I spent some time today commenting in deletion discussions on your Commons uploads. What is see is that your past reactivity has set up conditions where users don't assume good faith. If you get angry with them for that, you will just make it all worse. So ... my suggestion, take a deep breath. These are wikis, which means that anything can be fixed. Deleted files can be undeleted, they are not actually deleted, they are merely hidden. Blocked users can be unblocked. Now, I need to go pick up my daughter, 13. I'm 70, and she's the sixth of seven children.... She has nieces and a nephew older than her.... Good luck, we can chat later. --Abd (discuss • contribs) 22:56, 20 February 2015 (UTC)

 * I am up for your training, you may consider me your eighth kid if you wish. Shustov (discuss • contribs) 08:02, 21 February 2015 (UTC)
 * Okay, we start today. First, a rule to take on. If you think something is being done that is stupid, wrong, biased, against you, or ridiculous, stop. Do not write while you think that. Wait. Instead of acting, email me. Point to the situation. If I don't respond within a day or so, email me again! Remember, it's a wiki. Any mistake can be corrected. And the reward of patience is patience. --Abd (discuss • contribs) 15:51, 21 February 2015 (UTC)

Commons file deletion discussion
Anyway, I voted in but you should fix your account access problem ASAP and only use Shustov. As to that photo, I guessed that your comment about "courtesy of" was not about permission to use the photo, but was about the taking of the photo. Is that correct?

 * No, it was not about permission. All courtesies were addressed either to my son, or to his wife, or to both for providing me a possibility of taking some photos and clips of my grandson. That simple! Shustov (discuss • contribs) 05:48, 20 February 2015 (UTC)

Box/Please do not edit
The template you created as 'User:Box/Please do not edit' used the User: namespace and created an entry for a user named 'Box'. There is no such user, and you wouldn't be allowed to edit that user's space anyway. I have moved the page to User:Shustov/Box/Please do not edit. I would correct the link from your user page, but it's clear that you don't want others editing it, so you'll need to correct the link yourself. Note that, with the inclusion of the kicking image, this is a resource specific to your own user account rather than something we would want as a generic template (Template:) available to all Wikiversity users. Let me know if you have any questions. -- Dave Braunschweig (discuss • contribs) 01:29, 18 March 2015 (UTC)

 * I copied the idea of such template from wikipedia:ru:Участник:Well-Informed Optimist who posted the notice on his user Page, I only changed the template design and language. Strictly speaking, I would not mind my template available to all Wikiversity users but I will follow your advice. Thanks. Shustov (discuss • contribs) 03:19, 18 March 2015 (UTC)
 * Generally, the box is a Bad Idea. We generally disapprove of users editing the user page of another user, so your user page is protected anyway, against disruptive editing. The box will not stop bots from editing your page, such as CommonsDelinker from removing links to deleted Commons images. It simply looks unfriendly! And it did not allow Dave to correct the error, which he surely would have done. --Abd (discuss • contribs) 16:25, 18 March 2015 (UTC)

By the way, the reason that this userbox worked on ru.wiki is here: ruwiki User:Box. This could not be done here because of Single Unified Login! They created an account to accommodate userboxes. The account is blocked. See. The bots that are working on username unification are going to create quite a mess. I think those accounts will be automatically renamed and then any user boxes using them will fail. --Abd (discuss • contribs)16:34, 18 March 2015 (UTC)

 * So, shall I remove my box right away? And what about just changing the text there for "Please, edit your own User Page if you wish" ? Shustov (discuss • contribs) 20:26, 18 March 2015 (UTC)

 * There are two different issues here. Abd is warning you that problems are about to occur on the Russian wiki with the User:Box equivalent because of the renaming of accounts for Single Unified Login.  Separately, the box on your account here is more of a cultural interpretation.  You're welcome to include whatever you'd like on your user page that the community is willing to accept.  But since the only ones editing your user page are you (under three separate accounts) and two bots, the warning seems unnecessary, no matter what the warning would say.  To choose media to go with the warning that implies you're going to kick someone if they edit your page could be interpreted as quite hostile.  This may go over well in Russian culture, but it seems unnecessarily violent from a western perspective.  -- Dave Braunschweig (discuss • contribs) 20:46, 18 March 2015 (UTC)

 * There is no clear statement in the standard template warning that only a particular page user is allowed to edit any part of his/her user page. This fact has inspired me to insert a very polite and delicate Notice saying: "Please do not edit. This is a Wikiversity participant's page." On the other hand, your interpretation of Notice "as quite hostile" which "may go over well in Russian culture, but it seems unnecessarily violent from a western perspective" looks for me as a medieval-like prejudice and discrimination of all people with Russian background. Sorry!

By the way, your editing of my Notice template proves that above Notice wasn't so unnecessary! Shustov (discuss • contribs) 04:59, 19 March 2015 (UTC)

 * Please note that your notice template was not edited. It was moved, because it violated another (non-existent) user's space.  -- Dave Braunschweig (discuss • contribs) 12:33, 19 March 2015 (UTC)
 * Shustov, you have a tendency to easily react to the comments of others as hostile or wrong in some way. I don't think Dave was, for example, displaying a prejudice against Russians, only speculating on a possible cultural difference. Yes, you could take it the way you did. But why take it that way? A habit of taking things that way can and has gotten you into trouble elsewhere. Others may also be reactive and then you have made an enemy, and it can snowball, as on Commons. So a hint: notice your own reactivity, it will have some clear signs. And then make conscious choices. "Do I actually want to irritate or alienate the major active custodian of Wikiversity, who has been trying to help me?" He is quite tolerant, so don't worry about him. I'm pointing to your response here.
 * As he points out, your template was not edited. He has not warned or threatened you, he simply notified you that the template was moved, and left the editing of your user page, to point to the new location, to you, because of your request not to edit. The move was necessary, we don't normally allow users to create pages in the user space of another, which is what you did (i.e., User:Box/Please,do not edit). Because his move damaged your user page display, he then notified you and explained.
 * Nobody is demanding that you do or not do anything here (beyond maybe "don't create userpages for other users.") The userbox with you as the kickboxer is perhaps mildly offensive, and also mildly funny. However, my own suggestion is that the whole thing comes off as indicating easy offense. Without that request, Dave would have fixed your userbox link (fixing things like that is a common exception to the rule not to edit others' user pages, because it is obviously helpful).
 * So how about a new Shustov, who has mellowed and now enjoys life, sharing that with others? Is it possible at your age? Or are you stuck with whatever you decided to be years ago?
 * I'm old enough that I can firmly say to you, yes, it is possible, if you choose it. Good luck. --Abd (discuss • contribs) 13:46, 19 March 2015 (UTC)

 * Thank you both, Dave and Abd, for your patience and spending so much time on me while I am growing. I did change the image on the Notice; however, if you believe the Notice itself is no good, I will take it off right away. Your brand new but, anyway, Shustov (discuss • contribs) 17:26, 19 March 2015 (UTC)

 * If you look at the file File:635-lbs squat.gif history, you will find out: at the Date=2015-02-17 there was the Permission= there, but at the Date=2015-02-17 it was gone. The same story is with the other files mentioned above. Who did it and why??? Shustov (discuss • contribs) 17:00, 5 February 2017 (UTC)

 * These files are not your own work. You are pictured in the image / video, and so could not be the author. You must provide proper attribution and licensing for these images. Let me know if you have any questions. -- Dave Braunschweig (discuss • contribs) 19:19, 5 February 2017 (UTC)

 * Dear Dave Braunschweig: I do not see the answer to my above question. Therefore, I am asking again: "Who destroyed all 11 (eleven) licensing permissions from my files, when it was done and why"? Thanks, Shustov (discuss • contribs) 21:02, 5 February 2017 (UTC)

 * See Request custodian action. The files are not properly attributed or licensed. Please correct this. If it is not corrected within seven days, the files will be deleted. Also see Special:CentralAuth/Shustov. Your account is currently indefinitely blocked on five different wikis. Please be careful in responses and approach, as any violations of Blocking policy will result in a block here as well.   -- Dave Braunschweig (discuss • contribs) 21:20, 5 February 2017 (UTC)

 * At first, restore my eleven Permissions, please. And then, indicate precisely, for each file individually, what is wrong there. Thanks, Shustov (discuss • contribs) 21:44, 5 February 2017 (UTC)

 * There is evidence, documented at Commons:Commons:Deletion requests/Files uploaded by Shustov, that you are the subject of these videos. If you are the subject of the videos, you are not the person holding the camera, and they are not "selfies". The camera moves in the shots, so it is being held by someone else. The person holding the camera created these videos and has copyright to them. You must explicitly give credit to that person as the source of the videos. Any of these videos tagged as "own" or "selfie" will be deleted as invalid licensing. -- Dave Braunschweig (discuss • contribs) 23:26, 5 February 2017 (UTC)

 * Dear Dave Braunschweig: If I understand what has happened correctly, it's MaintenanceBot, who (or which?) deleted all my licensing permissions. Anyway, I assume that those permissions will be restored sooner or later and my primary task now is to respond to your remarks presented above, namely:

 * I won't argue about seven GIF-animations (as you called them "videos"), which, as you noticed, "move" but
 * What's wrong with the other four still images there?
 * Thanks, Shustov (discuss • contribs) 05:02, 6 February 2017 (UTC)
 * Dear Shustov, I think you already know that you need to specify the name of the person holding the camera while creating these videos and photos. Since it's clear that there was a person assisting you while creating these videos, it's pretty natural that someone was assisting you while shooting these photographs as well, that's why you have to provide the author's name for these four images as well. --Good Will Hunting (discuss • contribs) 07:21, 6 February 2017 (UTC)

It was brought to our attention that the original licensing was inaccurate and invalid. The inaccurate licensing was removed. In addition to accurate source information, accurate licensing consistent with the source must be provided on all files uploaded by Shustov and ShustovVal. Files that are not appropriately licensed and attributed will be deleted. I appreciate your desire to challenge the process, however, that is not going to be a productive approach. -- Dave Braunschweig (discuss • contribs) 13:37, 6 February 2017 (UTC)
 * Dear ! Just FYI, I'm currently trying to walk Shustov through the entire process once again (we're mostly talking on ruwiki pages). As you may have noticed, I already changed the name of the author on the following image File:635-lbs_squat.gif, and currently I'm trying to figure out what would be the best way to get confirmation from the person who made the actual images / videos via OTRS system. --Good Will Hunting (discuss • contribs) 14:20, 6 February 2017 (UTC)

 * By the way, Good Will Hunting, Kagan Yalaman still helped me with these files: File:Intensive training with barbel.gif, File:Partial squats with 585-lbs barbel.gif, File:Pulling 250-lbs weight.gif, File:Pulling-up 250-lbs weight (front).gif.

Rejuvenation
Hi Shustov!

Your Rejuvenation resource appears well developed and ready for learners! Would you like to have it announced on our Main Page News? --Marshallsumter (discuss • contribs) 01:08, 8 May 2017 (UTC)

 * Hi, Marshallsumter: Wouldn't it be better for me to keep a low profile after all that has happened before? Vshustov (discuss • contribs) 01:35, 8 May 2017 (UTC)

 * Hi Shustov! It's entirely up to you! I read your Rejuvenation resource and liked it! If there's no problem with your photographs, the resource is likely okay too. If there is, let me know, the photos can usually be handled by Fair use, especially if they occur on the web. --Marshallsumter (discuss • contribs) 02:14, 8 May 2017 (UTC)

 * You know, Marshallsumter: I have no problems with my photographs but some of our administrators may. Anyway, please, do as you believe is reasonable. Best! Vshustov (discuss • contribs) 05:29, 8 May 2017 (UTC)

 * Hi, Marshallsumter: Unfortunately, Dave Braunschweig has made an attempt to destroy the image File:The same man at 18 and 80 years old.jpg. Can you do something to stop it? Thanks! Vshustov (discuss • contribs) 19:22, 9 May 2017 (UTC)

 * Hi Shustov! I looked for this image on the web including your Norridge home page, but it's not there! Did these two images come from your personal collection? And, did you combine them? --Marshallsumter (discuss • contribs) 20:10, 9 May 2017 (UTC)

 * Yes, Marshallsumter: these two images came from my personal collection and I, really, did combine them together as the proof of possible Rejuvenation. Vshustov (discuss • contribs) 06:22, 10 May 2017 (UTC)

 * Whether or not the images came from your personal collection, and whether or not you combined them is not relevant to the discussion. As before, the issue is who took the photographs, and what rights you have to publish their work. As before, your continued avoidance of addressing the question suggests that you do not have the right to publish these photos. -- Dave Braunschweig (discuss • contribs) 12:33, 10 May 2017 (UTC)

 * You know, Dave Braunschweig, your word "discussion" above is the key point here. It was 18:07, 9 May 2017, when you, without sending me any message to provide a chance of "discussion", did what you did. Do you believe you had any right to behave like this? Vshustov (discuss • contribs) 17:34, 10 May 2017 (UTC)

 * See Request_custodian_action. Your contributions show a continued pattern of copyright violation. You are already blocked on five wikis due to copyright violations, self promotion, and interaction with other users. I encourage you not to continue this approach. Supply accurate copyright and license information for the file in question, or accept that the file will be deleted. -- Dave Braunschweig (discuss • contribs) 18:13, 10 May 2017 (UTC)

 * But what, Dave Braunschweig, about you not sending me any message-notification ?! Vshustov (discuss • contribs) 18:43, 10 May 2017 (UTC)

 * The notification would have been added by bot, and may be still be added the next time the bot is run. But I didn't run the bot because you had already indicated your awareness of the issue at and . -- Dave Braunschweig (discuss • contribs) 19:45, 10 May 2017 (UTC)

 * Bad bot! Vshustov (discuss • contribs) 21:40, 10 May 2017 (UTC)

 * The image is currently licensed as Creative Commons Attribution ShareAlike 3.0 Unported. If Dave puts the file up for deletion again the image can be put under Fair use. US copyright law, section 107, Fair use, does not require the copyright holder to be stated or known, nor does it require a source be stated or a rationale. We supply source, author, and rationale as a courtesy to users who view the file. The information you've supplied is acceptable for fair use. --Marshallsumter (discuss • contribs) 22:02, 9 May 2017 (UTC)

Because Shustov is in the picture, Shustov cannot list own as the source. Someone else took the picture and must be credited for it. That photographer determines the licensing. Fair Use is not relevant to the discussion, as WV:EDP requires that "Wikiversity content that is used under the fair use doctrine must be properly attributed to the copyright holder". -- Dave Braunschweig (discuss • contribs) 22:12, 9 May 2017 (UTC)

 * Well, selfies have been around for a long time. On older cameras they were a timer on the shutter. The photographer set the timer, took a position in the field of view and waited for the click. Fair use can be used for two reasons: (1) fair use is US law which does not require the copyright holder at all and (2) WV:EDP has never received any consensus approval, probably because some involved knew about point (1). So under fair use the burden of proof shifts to those claiming own is not the case. If any copyright holder wants their image taken down, we voluntarily comply, but until then if Shustov wishes to use fair use, the user can. For Creative Commons Attribution ShareAlike 3.0 Unported, Shustov would have to prove own. --Marshallsumter (discuss • contribs) 23:03, 9 May 2017 (UTC)

 * We've already been around this block. See discussions above from February. Shustov needs to indicate the photographer and appropriate license. A claim of Fair Use means that Shustov isn't the copyright owner and has no license to use the images. Without a source, they will be deleted. -- Dave Braunschweig (discuss • contribs) 01:02, 10 May 2017 (UTC)

 * As I mentioned with respect to fair use the copyright holder is irrelevant. It can be anyone or unknown. The letter and spirit of section 107 is an exemption from copyright holders. The fair use license is relevant if Shustov wants to use it. A source is not required for fair use, but we supply one as a courtesy. Shustov can be the source. --Marshallsumter (discuss • contribs) 02:46, 10 May 2017 (UTC)

 * The above discussions are extensive. I recall a notice on "Request for Custodian Action" that I responded to with the comment that these images could be handled with fair use. I refrained from any further involvement as Shustov did not ask for help or indicate any interest in fair use, similar so far to here regarding the latter. --Marshallsumter (discuss • contribs) 23:54, 10 May 2017 (UTC)

 * Hi, Marshallsumter! I apologize for my ignorance, but will you explain to me who wins? Thanks, Vshustov (discuss • contribs) 05:15, 11 May 2017 (UTC)

 * If Dave decides to, your composite image could be up for deletion again. If you like I can change the current license to fair use and fill in the appropriate information from your responses above. Fair use allows you to keep the image free from deletion so your resource wins, your learners win, and Wikiversity wins! I hope this helps. If you do not like it, I can change it back. It's up to you! --Marshallsumter (discuss • contribs) 05:31, 11 May 2017 (UTC)

 * I do like it, of course! Go ahead, please! Vshustov (discuss • contribs) 05:48, 11 May 2017 (UTC)

Please refer to WV:EDP items 6 and 8. "Wikiversity content that is used under the fair use doctrine must be properly attributed to the copyright holder.", and "Media files containing copyrighted material that do not comply with the intent and spirit of this policy can be deleted by custodians at any time." Unfortunately, your refusal to indicate the copyright holder of these images has resulted in a situation that violates Wikiversity's Exemption Doctrine Policy regarding Fair Use files. The file has been deleted. You may request Undelete at WV:RFD. It will be up to the community to determine whether the file may be restored. -- Dave Braunschweig (discuss • contribs) 13:15, 11 May 2017 (UTC)

 * Vshustov is the copyright holder and author for the composite of the two images! Now, I'm sorry but you have offered no proof that Shustov is not the copyright holder of the individual images. The first image may have been a selfie, given to the user with permission implied or otherwise to use as the user wishes, or inherited. The same may be true for the second. You have to prove otherwise and you have not done so. Proof does not consist of stating sections of an EDP that never received any kind of consensus. Nor does it consist of arguments. Proof must be factual! In addition the user owns their own image, if they give permission to have their image photographed with the expressed or implied consent that ownership, including copyright of that photograph and negative or digitally stored image, is legally transferred to the person photographed, then they own the image and copyright. Please restore the image. This is not a matter for "You may request Undelete at WV:RFD." --Marshallsumter (discuss • contribs) 15:32, 11 May 2017 (UTC)

 * This is in response to your, Dave Braunschweig, post dated 13:15, 11 May 2017 (UTC) where you said: "...your refusal to indicate the copyright holder of these images has resulted in ... The file has been deleted."  Now, see what happened: 1) At 18:07, 9 May 2017 (UTC), you deleted my name as the copyright holder from the file description and put the deadline for my new (??) indication of the copyright holder, namely May 16, 2017 (UTC).  2) Then, the above deadline disappeared(?!).  3) At 13:15, 11 May 2017 (UTC), you deleted my file.  My question is: "what is the reason for that rush?" Vshustov (discuss • contribs) 19:38, 11 May 2017 (UTC)

 * indicates source as own work and Shustov as the author. This is incorrect, as the original images are not your own work. You are the subject, not the creator. If a file at Wikiversity is improperly licensed, it may be removed after seven days. However, a Fair Use file is not an improperly licensed file. It is an unlicensed file. Unlicensed files that do not credit the source may be removed at any time, per WV:EDP. If you want the file to be posted at Wikiversity, you must credit the creator of the original images. -- Dave Braunschweig (discuss • contribs) 23:11, 11 May 2017 (UTC)

 * Well, we've been through this before. WV:EDP in any form cannot violate US copyright law which includes section 107. WV:EDP states: "Author: The media file creator, especially if different from the copyright holder." The composite is the user's own work. So the user is the creator or author of the composite. Section 107 does not require "author" or "creator" be stated! Nor do sections 106 or 106A or 104. We supply a source (not required by Section 107) and an author (not required by Section 107) as a courtesy. To require it is a clear violation of US copyright law specifically section 107. In the USA everyone is presumed innocent of a crime, violation of the law, unless proven guilty. Being forced to violate US law is a federal crime called duress. Whether a selfie or a commissioned portrait, you must prove they are not the user's own work, which you only assert. If an author or creator existed other than the user, anyone wishing to use the images or the composite, in this case, must discuss it with the user as all rights are the users. --Marshallsumter (discuss • contribs) 23:48, 11 May 2017 (UTC)

Hi Shustov!

Your Physical fitness resource appears ready for learners! Would you like to have it announced on our Main Page News? --Marshallsumter (discuss • contribs) 20:30, 28 May 2017 (UTC)

Copyright Violations
Your account is blocked for repeat copyright violations. See discussions at and  for background information. Files in violation have been deleted. To be unblocked, you must explicitly state here correct understanding of who owns the copyright to pictures that are taken and why indicating own work on pictures with you as the subject is invalid.

=Problem 3: Integral Mean Value Theorem =

Given
a function:

PART A) for all $$ x \epsilon\ [a,b] $$

PART B) for all $$ x \epsilon\ [a,b] $$

Find
PART A) Prove the integral mean value theorem given Equations 3.1 and 3.2 PART B) Prove the integral mean value theorem given Equations 3.1 and 3.3

Solution
Part (A) Define m,M as below,

Consider,

Integrating each side of the inequality,

where, m and M are constants by definition of (3.3 and 3.4) Multiplying (3.7) by $$\displaystyle \frac{1}{\int^b_a w(x)dx}$$ yields

Applying Intermediate Value Theorem,

Thus,

 * {| style="width:100%" border="0" align="left"

$$\displaystyle \begin{align} \therefore \int_a^b w(x) \cdot f(x)dx = f(\xi ) \int_a^b w(x)dx \quad _{for} \quad w(x) \geqq 0 \end{align} $$

 * }
 * }

Part (B) Another version of IMVT Either 1) w(x)>0 (done in Part(A)) or 2) w(x)<0

Define m,M as below,

Consider,

Integrating each side of the inequality, where, m and M are constants by definition of (3.3 and 3.4) Multiplying (3.13) by $$\displaystyle \frac{1}{\int^b_a |w(x)|dx}$$ yields

Since $$\displaystyle w(x)<0 $$, $$\displaystyle |w(x)| $$ becomes $$\displaystyle - w(x) $$,

Applying Intermediate Value Theorem,

Thus,

 * {| style="width:100%" border="0" align="left"

$$\displaystyle \begin{align} \therefore \int_a^b w(x) \cdot f(x)dx = f(\xi ) \int_a^b w(x)dx \quad _{for} \quad w(x) < 0 \end{align} $$

=Problem 1 - L'Hôpital's rule= From (meeting 3 page 1)

Given

 * {| style="width:100%" border="0" align="left"

f(x) = \frac{e^{x}-1}{x} $$ $$
 * $$\displaystyle
 * $$\displaystyle
 * $$\displaystyle (1-1)
 * }
 * }

Find
1. Find $$\displaystyle \lim \ f(x) $$ as $$\displaystyle \ x -> 0$$

2. Plot $$\displaystyle \ f(x) \ ; \ x \in [ 0,1 ]$$

1. Find $$\displaystyle \lim \ f(x) $$ as $$\displaystyle \ x -> 0$$
 We solved this on our own

[Background Knowledge] L'Hôpital's rule

According to L'Hôpital's rule,

 * {| style="width:100%" border="0" align="left"

$$
 * $$\displaystyle \lim_{x\rightarrow 0} \frac{e^{x}-1}{x} \ = \ \lim_{x\rightarrow 0} \frac{e^{x}}{1} \ = \ e^{0} \ = \ 1$$
 * $$\displaystyle (1-2)
 * $$\displaystyle (1-2)
 * }
 * }

 * {| style="width:100%" border="0" align="left"

 * }
 * }
 * }

 * {| style="width:100%" border="0" align="left"

Therefore,  $$\displaystyle \ \lim_{x\rightarrow 0} \frac{e^{x}-1}{x} \ = \ 1 $$

Categorising
Hi, and thanks for being so willing to categorise pages on Wikiversity! However, it might be more helpful if you gave categories meaningful names; I for one wouldn't be able to add Category:Egm5526.s11.arunas to any other category, as I have no idea what subject it is! Thanks again, Gaidheal1 00:58, 9 June 2011 (UTC)

Base isolation

Base isolation or seismic isolation is a collection of special units in a building resting on its foundation to provide separation of the building from the shaking ground thus improving its seismic performance. Base isolation takes 7 months to build. .

Basic parts of base isolation system
Base isolation system consists of isolation units with or without isolation components, where:

1. Isolation units are the basic elements of base isolation system which provide the mentioned separation effect to a building structure.

2. Isolation components are the connections between isolation units and other parts of the building having no separation effect of their own.

History
From the very beginning, the theory of base isolation rested on two pillars: heavy damping and frequency separation. Unfortunately, nobody paid any attention that the heavy damping was a sort of a strong connection between a substructure and superstructure, and that the idea of decoupling them with the help of such connections was of no good. Anyway, to virtually test-drive any design concept of base isolation, some online help is available now.

Example: [[media: 2010_09_07_14_59_22.djvu | p.7-3]] continued:

First condition of Exactness: For $$\displaystyle F(x,y,y')=0$$ to be exact, $$\displaystyle F(\cdot) $$ must be in the form:

[[media: 2010_09_09_13_54_49.djvu | Page 8-3]]

Satisfied 1st Condition of exactness (Not necessarily exact yet-Need to satisfy 2nd condition)

Eqs.(2)&(3) [[media: 2010_09_07_14_59_22.djvu | p.7-2]] also satisfy 1st condition of exactness

Eqs.(4)[[media: 2010_09_07_14_59_22.djvu | p.7-2]]:

Example:

Above equation does not satisfy 1st condition of exactness.

(1)&(2)[[media: 2010_09_09_13_54_49.djvu | p.8-2]]: If $$\displaystyle \phi $$exists, what would be the relationship between the two equations?

Can M(x,y) and N(x,y) be arbitrary? No!

Since

Assuming $$\displaystyle \phi(\cdot, \cdot)$$ is smooth
