Performativity Of Models, Rajesh Venkatachalapathy Feb 2019

Performativity Of Models, Rajesh Venkatachalapathy

Systems Science Friday Noon Seminar Series

Inspired by Latour's work in social studies of science and technology, Callon, MacKenzie and others developed a performativity critique of economics. Building on this, Healy (2015) recently discussed the performativity of network models. While useful, I move away from French continental philosophy to avoid unavoidable comparisons with Foucauldian conceptions of performativity. Instead, I use ideas from vanilla historical sociology of science and technology and cognitive science to understand performativity.

I first discuss Healy's critique of network models. Keeping with the worst traditions in systems science, I greedily apply this concept to all models in science and engineering by first critiquing …


What If Our Beliefs About A System Are Not Wholly Accurate? What If?, Gary Langford Feb 2019

What If Our Beliefs About A System Are Not Wholly Accurate? What If?, Gary Langford

Systems Science Friday Noon Seminar Series

For most people, a system is a construct with vexing complexities, many many parts, and perhaps wrapped with a goal or intention. Add to that simple construct a set of terminologies that are commonly applied when speaking of “systems” and we just might have veered away from discoveries of imminent importance. Ask yourself, “You said it was a system, but how did that statement help you solve your problem? How far off would we have to be in our perception of systemsness for us to make mistakes of consequence? One Hundred Billion are lost annually in software projects that failed …


Civic Ecology: Living Community Systems For Sustainability, Tim Smith Nov 2012

Civic Ecology: Living Community Systems For Sustainability, Tim Smith

Systems Science Friday Noon Seminar Series

Civic Ecology is a stakeholder-driven, whole systems framework for creating sustainable communities. The framework focuses on empowering citizens of all ages, cultures, and abilities to envision, create, and manage their community’s unique “software” -- the integrated energy, nutrient, water, waste, material, and food systems, as well as economic flows and cultural interactions that animate their place. Exploring and supporting these flows allows communities to enhance their local wealth (environmental, economic, and social), resilience, and competitiveness, and help them take control of designing and managing their future through collaboration and innovation. The Civic Ecology framework can be the foundation upon which …


System Dynamics Modeling Of Prescription Opioid Pain Reliever Abuse, Alexandra Nielsen Oct 2012

System Dynamics Modeling Of Prescription Opioid Pain Reliever Abuse, Alexandra Nielsen

Systems Science Friday Noon Seminar Series

The nonmedical use of prescription opioid pain relievers and associated overdose deaths have been labeled an epidemic by the Centers of Disease Control and Prevention. While these medicines play an important role in the treatment of pain, the benefits of opioids for the treatment of pain need to be balanced against these very real risks. Alex has been working closely with Professor Wayne Wakeland, Teresa Schmidt, and Dr. Dennis McCarty (OHSU) to create a dynamic systems-level model of opioid use, abuse, and diversion in order to give context to current research in this area and to provide a better understanding …


Complexity Theory And Political Change: Talcott Parsons Occupies Wall Street, Martin Zwick Jan 2012

Complexity Theory And Political Change: Talcott Parsons Occupies Wall Street, Martin Zwick

Systems Science Friday Noon Seminar Series

Complexity theory can assist our understanding of social systems and social phenomena. This paper illustrates this assertion by linking Talcott Parsons' model of societal structure to the Occupy Wall Street movement. Parsons' model is used to organize ideas about the underlying causes of the recession that currently afflicts the US. While being too abstract to depict the immediate factors that precipitated this crisis, the model is employed to articulate the argument that vulnerability to this type of event results from flaws in societal structure. This implies that such crises can be avoided only if, in Parsons' terms, structural change occurs …


Participatory Action Research: Science And Social Change, Dora Raymaker Oct 2011

Participatory Action Research: Science And Social Change, Dora Raymaker

Systems Science Friday Noon Seminar Series

Participatory Action Research (PAR) is a general collaborative approach to inquiry that includes research "subjects" as members of the research team. Useful in any setting involving groups of people, PAR has revolutionized research with minority communities. Some "flavors" of PAR, such as Community-Based Participatory Research (CBPR) have been developed to address issues of power and privilege, to change dynamics between science, society, and minorities, and to enable and encourage systems change. This talk discusses the theory and practice of PAR as a research approach, drawing from real world examples in health sciences research with minority communities defined by disability or …


The Illicit Arms Trade: A Social Network Analysis, David Todd Kinsella Mar 2011

The Illicit Arms Trade: A Social Network Analysis, David Todd Kinsella

Systems Science Friday Noon Seminar Series

In recent years, researchers have increasingly turned their attention to the proliferation of small arms and light weapons. Small arms are difficult to track and are not the stuff of military parades, but they are immensely destructive. In addition to what is already circulating, a substantial percentage of what is newly produced enters the black market and is destined for conflict zones across the globe. I argue that the illicit trade in small arms shares some important properties with networked forms of organization studied by sociologists. I then employ quantitative methods developed for the study of social networks in an …


Gender And The Social Structure Of Collaboration, Kjersten Bunker Whittington Nov 2010

Gender And The Social Structure Of Collaboration, Kjersten Bunker Whittington

Systems Science Friday Noon Seminar Series

Previous research demonstrates that individuals’ network positions in their surrounding social structure of relations influence the extent of their output and performance. The unique situation of minority groups complicates the relationship, however, as issues of status, legitimacy, and marginality influence the flow and interpretation of information and resources. While several scholars have addressed differences in male and female networks in the workplace, the association between macro-level work arrangements and the micro-level interaction mechanisms of minority groups is unclear. Greater insight into stratification processes can be gained by studying how organizational forms affect the way men’s and women’s networks are structured …


The Limits Of Control, Or How I Learned To Stop Worrying And Love Regulation (Discussion), Joshua Hughes Nov 2010

The Limits Of Control, Or How I Learned To Stop Worrying And Love Regulation (Discussion), Joshua Hughes

Systems Science Friday Noon Seminar Series

When we want to solve a problem, we talk about how we might manage or regulate—control it. Control is a a central concept in systems science, along with system, environment, utility, and information. With his information-theoretic Law of Requisite Variety, Ashby proved that to control a system we need as much variability in our regulator as we have in our system (“only variety can destroy variety”), something like a method of control for everything we want to control. For engineered systems, this appears to be the case (at least sometimes). But what about for social systems? Does a group of …


What Makes A Meaningful Universe?, Todd Duncan, James Butler Apr 2010

What Makes A Meaningful Universe?, Todd Duncan, James Butler

Systems Science Friday Noon Seminar Series

A common line of thinking says that although we feel subjectively that our thoughts and actions matter in some way, this perception is an illusion. According to this view, an honest look around at the universe shatters this myth and reveals that our lives are ultimately meaningless. If we are to be hard-nosed realists, limiting ourselves to scientific, evidence-based reasoning, then we must accept that human existence is an inconsequential accident of no ultimate significance in the grand scheme of things. Is this attitude really justified by the evidence? We'll explore this question by taking a step back and asking …


Holism And Human History, Martin Zwick Apr 2010

Holism And Human History, Martin Zwick

Systems Science Friday Noon Seminar Series

This paper uses a systems-theoretic model to structure an account of human history. According to the model, a process, after its beginning and early development, often reaches a critical stage where it encounters some limitation. If the limitation is overcome, development does not face a comparable challenge until a second critical juncture is reached, where obstacles to further advance are more severe. At the first juncture, continued development requires some complexity-managing innovation; at the second, it needs some event of systemic integration in which the old organizing principle of the process is replaced by a new principle. Overcoming the first …


Reconstructability Analysis Of Elementary Cellular Automata, Martin Zwick, Hui Shi Mar 2010

Reconstructability Analysis Of Elementary Cellular Automata, Martin Zwick, Hui Shi

Systems Science Friday Noon Seminar Series

Reconstructability analysis is a method to determine whether a multivariate relation, defined set- or information-theoretically, is decomposable with or without loss (reduction in constraint) into lower ordinality relations. Set-theoretic reconstructability analysis (SRA) is used to characterize the mappings of elementary cellular automata. The degree of lossless decomposition possible for each mapping is more effective than the λ parameter (Walker & Ashby, Langton) as a predictor of chaotic dynamics.

Complete SRA yields not only the simplest lossless structure but also a vector of losses of all decomposed structures, indexed by parameter, τ. This vector subsumes λ, Wuensche’s Z parameter, and Walker …


Criticisms Of Systems Science, Joshua Hughes Jan 2010

Criticisms Of Systems Science, Joshua Hughes

Systems Science Friday Noon Seminar Series

A new year often begins with a sense of optimism, but we (ever the contrarians) will begin it with a healthy dose of pessimism. This week's seminar will be a discussion about criticisms of systems science. As Winston Churchill said, "Criticism may not be agreeable, but it is necessary. It fulfills the same function as pain in the human body. It calls attention to an unhealthy state of things." Is the systems project in an unhealthy state? Since its emergence in the 1940s and 1950s, a number of people have believed that to be the case, and a few have …


Creating Insanity In Learning Systems: Addressing Ambiguity Effects Of Predicting Non-Linear Continuous Valued Functions With Reconstructabilty Analysis From Large Categorically Valued Input Data Sets, William D. Eisenhauer Dec 2009

Creating Insanity In Learning Systems: Addressing Ambiguity Effects Of Predicting Non-Linear Continuous Valued Functions With Reconstructabilty Analysis From Large Categorically Valued Input Data Sets, William D. Eisenhauer

Systems Science Friday Noon Seminar Series

Being told to give two different, and potentially counter, responses to the same stimulus can set up a double bind in humans, leading to a type of insanity. So what how do you deal with it when it comes up quite frequently in modeling through simplification and removal of predictive variables?

In his current dissertation research Ike Eisenhauer is using reconstructability analysis to implement K-System, U-System, and B-System approaches to predict a continuously valued function through discrete categorically valued input variables [e.g. textual data]. One of the key issues is how to address the inability of K-Systems and U-Systems to …


Generalists, Specialists, And The Best Experts: Where Do Systems Thinkers Fit In?, Joshua Hughes Nov 2009

Generalists, Specialists, And The Best Experts: Where Do Systems Thinkers Fit In?, Joshua Hughes

Systems Science Friday Noon Seminar Series

GENERALIST / SPECIALIST: A generalist is someone who has studied a little bit of everything, and in the end knows nothing well in particular. By contrast, a specialist is someone who has studied a single subject, and as a consequence does not even know his own subject, because every item of knowledge is related to other components of the whole system. The good scholar or scientist--like the good chef, manager, clinician, or orchestra conductor--is an expert in one field or craft, and knowledgeable in many. Like a mouse, he can explore the details of a terrain; and, like an owl, …
