LOCATION: Harder House, Room 104

PRESENTER: Diana Fisher

TITLE: Room Introducing Systems Concepts Children Can Learn K-12. Followed by a demo of the iPad version of STELLA.

SUMMARY: It is increasingly evident that understanding problems from a holistic, systemic perspective is essential in dealing with many of our most serious problems. It makes sense, therefore, to start helping students develop systems thinking and systems model-building skills early. This talk will present a list of numerous systems thinking and system dynamics model-building skills that have been successfully taught to children K-12, compiled by educators who have worked with these concepts with students in K-12 for over 20 years. It will provide an explanation of some resources for starting the education of your own children, if such skills are not taught in your child’s school. Parents are, of course, the most important and first teacher.

Additionally, a demonstration of STELLA Modeler, the newest STELLA app for the iPad, which will debut on October 31, will be given. The software is more complete than expected and will cost (anticipated) $39.99. It is a very nicely designed application.

BIO: Diana Fisher is a Ph.D. student in the Systems Science Graduate Program at Portland State University (with emphasis on System Dynamics Modeling, especially in math and science instruction).

TITLE: Is the Materialist Neo-Darwinian Conception of Nature False?

SUMMARY:

This paper assesses the main argument of Thomas Nagel’s recent book, Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False. The paper agrees with Nagel that, as an approach to the relation between mind and matter and the mystery of subjective experience, neutral monism is more likely to be true than either materialism or idealism. It disagrees with Nagel by favoring a version of neutral monism based on emergence rather than on a reductive pan-psychism. However, the paper invokes a reductive view when applied to information (as opposed to psyche), and posits a hierarchy of types of information that span the domains of matter, life, and mind. Subjective experience is emergent, but also continuous with informational phenomena at lower levels.

The paper is available at: http://www.pdx.edu/sysc/sites/www.pdx.edu.sysc/files/NPC13_Nagel.pdf

BIO: Martin Zwick has been teaching and doing research in the Systems Science Graduate Program since 1976.

TITLE: Success Story: The Mayo Clinic Anemia Management System (MCAMS)

SUMMARY: Uncovering a Classic Misunderstanding of Endogenous Delays: Two Decades of Ineffective Anemia Management in Kidney Dialysis Patients
- Identifying the Problem with System Thinking
- Solving the Problem with System Dynamics

PROBLEM: Uncovering healthy kidneys releast hormone erythropoietin (EPO) which stimulates red blood cells production in the bone marrow. This hormone is absent in end-stage disease, so in addition to the obvious requirement for dialysis, recombinant (closed) EPO must be administered to avoid severe anemia. However, several interacting feedback delays conspire to produce oscillations in hemoglobin levels, with typical periods of three to four months. Lower Hgb levels lead to profound fatigue and cognitive difficulties; high Hgb levels increase blood viscosity, increasing the risk of congestive heart failure, heart attacks, and strokes. In addition, EPO is very expensive, costing thousands of dollars per patient per year.

MODEL: We developed a model that takes into account: (i) the dose and timing of EPO administration; (ii) the duration of EPO in the body; (iii) the 10-15 day lag in RBC production following EPO administration; and (iv) the lifespan of circulating RBC's, which range from 120 days in healthy individuals to 50-80 days in dialysis patients. Historical data is imported into the model, followed by Monte Carlo simulations to infer a set of biological parameters that are consistent with EPO doses ('perturbations') and Hgb responses ('transient responses') in each individual patient.

RESULTS: (i) MCAMS has been applied to over 600 patients, leading to virtually total elimination of undesirable Hgb oscillations. (ii) Clinicians previously managed anemia in 60-80 patients; a single data analyst and one clinician now manage over 500 patients in approximately one day per week. (iii) Patients report noticeable improvements in quality of life. (iv) EPO doses have been reduced by about 40% at considerable savings in cost. (v) Given consistent and reliable Hgb levels, decreasing Hgb values are quickly flagged for closer analysis by clinicians. Typical reasons include unrecognized GI bleeding, or inflammation such as poor wound healing in diabetic patients. Previously, this crucial data was totally lost in the noise of Hgb oscillations. As a result, these issues are identified and treated much sooner, leading rto a 20% reduction in annual hospitalization days within the dialysis patient population. Taken together, cost savings are estimated at about $4M per year.

BIO: Dr. Ed Gallaher received a Ph.D. in Pharmacology from the University of Washington Medical School. This was followed by postdoctoral research at Stanford, and seven years as a Principal Investigator at the VA Medical Center in Palo Alto. In 1986 he moved to Portland, with joint appointments at the VA Medical Center, and the Departments of Pharmacology and Behavioral Neuroscience. His research focused on drug tolerance and physical dependence, using system dynamics as an organizational framework for the underlying biological processes. He collaborated on a Portland Public Schools NSF grant to provide System Dynamics training to K-12 teachers, and PPS collaborated with him on an NIH education grant: SimHealth: Health Education via System Dynamics Modeling and Simulation.

Based on the effectiveness of these programs, he recently co-founded RxSim, Inc., to develop and market tools for 'ordinary folks' to help them understand and better manage medications for themselves and their immediate families.

PRESENTER: Michael Chad Miller

TITLE:  Global Resource Management of Response Surface Methodology   

SUMMARY: Statistical research can be more difficult to plan than other kinds of projects, since the research must adapt as knowledge is gained. This dissertation establishes a formal language and methodology for designing experimental research strategies with limited resources. It is a mathematically rigorous extension of a sequential and adaptive form of statistical research called response surface methodology. It uses sponsor-given information, conditions, and resource constraints to decompose an overall project into individual stages. At each stage, a "parent" decision-maker determines what design of experimentation to do for its stage of research, and adapts to the feedback from that research's potential "children," each of whom deal with a different possible state of knowledge resulting from the experimentation of the "parent." The research of this dissertation extends the real-world rigor of the statistical field of design of experiments to develop a deterministic, adaptive algorithm that produces deterministically generated, reproducible, testable, defendable, adaptive, resource-constrained multi-stage experimental schedules without having to spend physical resource. 

BIO: Michael Chad Miller is a doctoral candidate in the Systems Science: Mathematics Ph.D. Program, and has earned a BS and a MS in Mathematics at PSU.

PRESENTER: Darcy Winslow

TITLE: Transformational Change at a Scale that Matters

SUMMARY: Natural systems demonstrate harmony, balance, interdependence and balancing competition and cooperation. However, modern industrial expansion has disrupted most if not all natural systems, and some would argue a few have reached a tipping point from which they may not return. I will share a few examples where taking a systems approach is resulting in unprecedented, pre-competitive collaboration that is showing positive change in critical systems. These will include examples at Nike and in the larger sports product industry, as well as in education and marine eco-systems through the work of the Academy for Systemic Change. All of these require participation across sectors, and have implications in the economic, environmental, social and political realms.

BIO: Darcy Winslow is the Managing Partner of the Academy for Systemic Change, an organization focused on unlocking the human spirit and building capacity in business, education and marine ecosystems to create systemic change for social, economic and environmental well-being at a scale that matters. In 2008, Darcy founded DSW Collective, LLC, which focuses on the alignment of organizational values and principles with the development and implementation of practical yet aggressive systemic sustainable design strategies.
Before starting her business she worked at Nike, Inc. for over 20 years and held several senior management positions within the business and the Nike Foundation, most notably starting the Sustainable Business Strategies in 1999, Senior Advisor to the Nike Foundation, Global Director for Research Design and Development and as General Manager/VP for Nike’s Global Women’s Footwear, Apparel and Equipment division.
Darcy received her BS in Exercise Science, studied Sports Medicine, and received her MS in Exercise Physiology and Biomechanics, and is a 2003 graduate of the Stanford Executive Program.

PRESENTER: Martin Zwick

TITLE: Using Information Theory to Discover Relationships in Data

SUMMARY:    This talk will introduce Reconstructability Analysis (RA), a machine learning methodology developed in the systems community based on information theory and graph theory.  RA is a member of the family of methods known as ‘graphical models,’ which also include Bayesian networks and log-linear techniques. It is explicitly designed for exploratory modeling, i.e., for discovery of unknown relationships in data, although it can also be used for confirmatory hypothesis testing.  RA can discover complex and nonlinear interaction effects that are not hypothesized in advance.

The talk will present an overview of basic theory and typical applications of RA. It will introduce OCCAM, the RA software package developed at PSU that is web accessible and freely usable for research.  (Research collaborations are invited!)  The web page on this methodology, which includes tutorials, access to the software, and a user’s manual, is

TITLE: Predicting Patient Outcomes in Total Joint Arthroplasty: The Role of Reconstructability Analysis

SUMMARY: Reconstructability Analysis (RA) constructed predictive models may be useful in health outcomes research in general and more specifically in assessing physician performance under new payment systems. In healthcare reimbursement, payment is increasingly tied to performance based on outcomes. Understanding a patient’s expected outcomes upon hospital admission provides a measure of performance which can be built into the structure of payment arrangements. Predictive risk modeling can be of assistance in meeting the challenges of providing quality healthcare with limited resources. This presentation provides an overview of a study testing the expectation that RA can perform as well as Logistic Regression in predicting outcomes in hip and knee replacement surgeries and that it may in fact provide additional accuracy through detection of interaction effects.

TITLE: Creating a Dynamic Model of Recovery from Concussion

SUMMARY: Although most patients recover relatively quickly from concussion, and are left with minimal if any deficits, there is considerable variation in recovery trajectories. We do not understand very well the reasons for these differences, nor do we understand very well how the various treatments and therapies contribute to these outcome trajectories.  Because concussion recovery involves complex and dynamic interactions between physiology, cognition, and other factors, linear analysis methods have proved to have limited value.  Consequently, concussion researchers recently initiated a collaboration with system scientists to create a nonlinear dynamic model. 

The modeling team is employing the system dynamics method as a tool for building the model, and is doing so in a collaborative fashion with the subject matter experts.

Our talk will focus on the process being employed, with the specifics of concussion model provided for illustrative purposes.

Title: 
Reconstructability analysis of household water use data 

Abstract:  Augmenting a recent urban sustainability study by PSU’s Vivek Shandas et. al. titled “The implications of climate change on residential water use: a micro-scale analysis of Portland (OR), USA”,  Marcus Harris and Martin Zwick use Reconstructability Analysis as an exploratory tool to detect non-linear and multi-variable relations between local climate data, individual household characteristics, and water use. The current study finds interactions between household and climate variables predictive of water use that are consistent with the prior study, but also finds new significant predictive interaction effects between different household variables.  In addition, the current study compares the effectiveness of water use prediction via RA and regression analysis.

Bio: Marcus Harris is a core Systems Science PhD candidate with a primary research interest in the advancement of reconstructability analysis as a general tool for discrete and continuous prediction.   He lives with his wife and three children in Newberg and enjoys spending time with them when he’s not at school.

Title: 
A Particle Dynamics Model for the Emergence of a Metabolism
 

Summary: In studies of the Origin of Life, one major hurdle is determining how a prebiotic system could maintain its state, far from environment or equilibrium, without the features of a living system. A suggested mechanism for overcoming this obstacle is an autocatalytic reaction network: a set of polymers whose members catalyze the reactions of other members, forming feedback loops and acting like a metabolism. To date, research on this topic has predominately focused on differential equation models, describing aggregate reaction rates and concentrations. These networks have not yet been studied with a physics-based, molecular dynamics model, with discrete agents and spatial heterogeneity. This seminar will present the results from such a model, and will show how the results from the different methods compare and contrast. (This work represents the first half of the presenter's Ph.D. research.)

Bio: Joe Fusion is a Systems Science Ph.D. candidate with research interests in systems modeling, data mining, complex systems, theoretical biology, and so on.

Title: 
 Modeling utilization of the Neuropsychological Examination in Criminal Forensics 

Summary:  The Criminal Justice Supersystem is presented as a system of systems. The forensic neuropsychological examination is a key component, interpreted differently by different systems, in aiding the court to adjudicate criminal cases. The principle role of the neuropsychological examination and report of findings is in advising on matters of trial competency, criminal responsibility (including Guilty Except for Insanity pleas), and sentencing mitigation. Understanding his/her role within a complex network of systems may increase the utility of the neuropsychologist's influence. Just what that influence is depends on the connection links and strengths within the network.

Title:  
An Empirical Defense of Cultural Darwinism  

Summary:  Description: Cultural Darwinism is the thesis that some populations of cultural entities undergo Darwinian natural selection. Cultural Darwinism has been criticized on many grounds, including that (1) it is not operational, (2) it is false, (3) it is not a fruitful and legitimate empirical science, and (4) it presupposes a false atomistic view of culture. This talk provides an empirical defense of cultural Darwinism, by analyzing data in the patent record for evidence of the Darwinian processes in the evolution of technology, and by responding to objections (1) - (4).

Title:   Racial/Ethnic and socioeconomic determinants of health: Investigating behavioral, psychological and social pathways

Summary:  This talk will be centered on a recently approved dissertation proposal that will investigate behavioral, psychological and social (B, P, S) factors as mediating variables in the Race/ethnicity—health outcomes link. Based on a conceptual model that links race/ethnicity and socioeconomic status (SES) to mediators (BPS), and BPS variables to health outcome (H) variables, the primary objective of the study is to investigate if these pathways differ for various races/ethnicities resulting in observed racial/ethnic health disparities. When standard statistical techniques are employed to test several mediation models, SES effects will be controlled for. Reconstructability analysis (RA) will also be used to investigate associations between various components of the conceptual model and select the most important variables for further causal modeling. RA is, then, used to determine paths from race/ethnicity and SES to the mediating variables (BPS) and from BPS to health outcome (H) variables where race/ethnicity and SES interactions are allowed while predicting the mediators (B, P, S).

Speaker:  David Percy

Title: Spatial Informatics and the Semantic Web

Summary:  
The Semantic Web was envisioned by Tim Berniers-Lee (inventor of the
WWW) as the next generation of the WWW in which all of the information
on the web is categorized such that it is understandable both by
machines and humans. It is also know as the Web 3.0.

The spatial version is involved in making GIS data available as
pervasive web services. This will allow researchers and other users to
use intelligent queries (or agents) to find exactly what they are
looking for using sophisticated queries on concepts from ontologies
where concepts are classified hierarchically such that a term "knows"
that it is part of one or more concept, and contains other subjects.
This is essentially the study of mereology (wholes and parts).

One of the many difficulties in making this vision real is getting
stakeholders to agree on a common set of semantic and syntactic
decisions regarding how their discipline's data are organized. This
talk will be about the current state of this broad subject, with a
focus on how it applies to Geology, which is primarily the author's
domain. Example maps will be shown.

Bio:
David Percy has been the Geospatial Data Manager for Portland State
University's Geology Department since 1998. Before that, he spent 15
years as a database manager and programmer in the field of medical
research. He retrained as a geologist in order to use his skills in
the field of Earth Science. Since 1999 he has taught technology
courses related to GIS, developing new courses such as GIS for the
Natural Sciences, GIS Programming (Python) and Web GIS at the
university. He recently (2012) added a Geoinformatics (Spatial
Informatics, now) course to the curriculum, and in 2014 made it into
an online course.

"Percy", as he is known by friends and colleagues, is actively
involved in the Open Source GIS movement through OSGEO and co-founded
the Portland area OSGeo chapter in 2008, which is hosting the

Title: Characterizing Computational Complexity in Geographic Optimization Problems

Summary: Most geographic allocation problems are combinatorial optimization problems that cannot be solved in polynomial time when the size of the problem increases. Such problems usually are "solved" (or approximated) by meta-heuristic approaches, such as simulated annealing, tabu search, and genetic algorithm. Meta-heuristic methods use various search strategies to explore and exploit the solution space until near-optimal solutions are located. This talk introduces the use of simulated annealing for solving geographic optimization problems that have spatial patterns as the decision objectives and ways of improving the computational performance of simulated annealing. An empirical approach to characterizing the computational complexity of geographic optimization problems is also presented.

Bio: Dr. Geoffrey Duh is an Associate Professor and Director of GIS Programs in Geography at Portland State University. He has a bachelor and a master degree in geography from National Taiwan University and a PhD in Nature Resources and Environment from the University of Michigan. His research focuses on developing geo-computational theory and techniques for the integration of GIS and remote sensing in spatial decision-making. He uses spatial modeling, simulation, and optimization techniques in applications such as land-use planning, emergency planning, and resources management. His most recent projects involve developing GIS for water forecasting for the National Water and Climate Center at the US Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS) and the prototyping of web-based GIS for performance-based budgeting for the US Army Corps of Engineers.

Title: A Pair of Guide Robots for PSU

Summary:  Since Fall of 2011 my students and me design a pair of companion robots to become guides for the Maseeh School of Engineering and Computer Science at PSU. The robots are built upon request of Dean of Engineering to guide various groups of visitors to two engineering buildings.  Although they belong to what is called “the Museum Guide robots”, some additional properties are being designed and programmed for them.
 
The first robot, called MCECSBOT, or Mr. Jeeves unofficially, is a human-sized humanoid robot on wheels designed from scratch. He is supposed to have a personality of a kind butler. The second robot, called Countess Quanta is a wheeled robot based on commercial robot PEOPLE-BOT design, with added arms and head. The name comes from her ability to count on fingers and her brain based on quantum logic, as well as a proud  personality and manners of this robot.
 
The talk will briefly present issues of mechanical, electrical, sensor, and system design of the robots but will concentrate on human-robot interface and Machine Learning/Robot Vision work done in our team since 2010. The issues of designing personalities of robots will be also touched upon as an introduction to discussion.

Title: Integrating Top-Down and Bottom-Up Datasets: Exploring participatory mapping for city planning

Summary:
Although collaborative governance has become a common term in managing cities, techniques for engaging ‘the publics’ in collective decision-making remain underdeveloped. Several limitations -- including access to lower income people or people of color, processes for sustaining engagement, and balancing the technical and socio-political dimensions -- prevent broadly inclusive processes in collaborative governance. Needed are techniques that solicit information about resources of value, as well as their locations and an understanding about local priorities for conservation. Arguably, linking these local or 'bottom up' perspectives with traditional urban planning information can result in decisions that are viable, context-specific, and sustainable. We use a locally developed, online, spatially-explicit survey tool, the Sustaining Urban Places Research Map (www.suprmap.org <http://www.suprmap.org> ) to engage community members and describe the assets of their neighborhood. By presenting a framework for linking people, process, and technology, we describe an engagement process containing several neighborhoods in Portland, Oregon. This presentation will describe several promising practices and consistent challenges in using online spatially-explicit participatory processes in city planning, especially when aiming to bridge the gap between expert and local influence in decision-making. The case study further describes the process for integrating local knowledge about a neighborhood (bottom-up information) with data from public agencies (top-down information), thereby offering a mechanism for ensuring that local knowledge about a neighborhood is is considered in collaborative governance processes.

Bio: I am an Associate Professor in the Nohad A. Toulan School of  Urban Studies and Planning at Portland State University. As the founder of PSU's Sustaining Urban Places Research Lab (SUPR Lab, www.suprlab.org <http://www.suprlab.org> ), our team focuses on three  substantive areas of investigation: (1) examining feedbacks between  environmental change and human behavior; (2) developing community-based  indicators for measuring the social and environmental conditions; and (3) characterizing the relationship between urban development  patterns and environmental quality. Prior to serving at Portland State University, I  was a school teacher in Oregon (Vernonia); curriculum developer in California (San Jose); and, a health and environmental policy  analyst for the Governor of New York State (Albany).

Title: "Freedom as a Natural Phenomenon"

Summary: "This phenomenon of “freedom” in the natural world – and indirectly the question of free will – is explored using systems-theoretic concepts that link the idea of freedom to ideas about autonomy and agency. The focus is on living systems in general, and on living systems that have cognitive subsystems more specifically. After touching on the relevance to freedom of determinism vs. randomness, the paper examines four types of freedom: (i) independence from fixed materiality, (ii) activeness that is unblocked and holistic, (iii) internal rather than external determination, and (iv) regulation by an informational subsystem. These types of freedom are not all-or-nothing but matters of degree."

Title: Using Equality as a Means to Sustain Cooperation in Iterated Prisoner's Dilemmas

Summary: In The Evolution of Cooperation, Robert Axelrod discusses the wide-spread applicability of the iterated PD and how cooperation in such a setup might be achieved and maintained. In The Complexity of Cooperation, he elaborates on how his original maxims might need to be modified to account for noise, or even for the arrival of agents/subjects who might not be innately inclined to cooperate. Christan attempts to build on this by exploring the prospect of using egalitarianism as a proxy metric innately cooperative agents could use to sustain cooperative environments in the face of some noise or agents/subjects who are disinclined to cooperate.

Title Materialism, personal food projects, and satisfaction: a phenomenological study of Urban Gardening in Portland, Oregon

Abstract: Leisure activities such as gardening and cooking are often correlated with increased well-being and happiness. Additionally, leisure activities such as gardening and food preparation are often internally motivated, and provide observable examples of self-concordant experiences. Self-concordance, i.e., internalized motivation, has been shown to increase satisfaction and increase efficacy of goal attainment. Further, experiential hobbies such as gardening may help individuals feel more satisfied, adopt more intrinsic life aspirations, and be less materialistic.

This study explored satisfaction, materialism, and food activities by focusing on first-person, lived experiences of eight urban gardeners in Portland Oregon who grow, prepare, and eat their own food. Little is known about what specific food experiences lead to increased feelings of well-being and satisfaction. Whereas previous research focused on defining and assessing materialism based on life aspiration measures, this study explored how intrinsic life aspirations translate into concrete, lived experiences expressed through food activities. The goal of the current study was to gain a deeper understanding of how food experiences satisfied the psychological needs of urban gardeners.

Qualitative analysis of interviews and other data revealed that food experiences: 1) were motivated by intrinsic reasons, such as competency, creativity, and curiosity, and also sometimes for extrinsic reasons such as status and security, 2) were affected by enabling factors such as social relationships, and disabling factors such as time, energy, and financial limitations, and 3) resulted in increased life satisfaction, and feelings of strength, and confidence. Additionally, participants’ level of general materialism often corresponded with their level of materialism regarding their food experiences.

The results indicated that individually tailored experiential long-term food related hobbies are highly valued and a source of great satisfaction for a variety of psychological needs, such as relatedness, connection, work-life balance, and abundance. These results show that food activities can be intrinsically satisfying and can mitigate the negative effects of materialism. The findings from this study build theory and provide direction for potential future research in reducing materialism by developing measures for types of satisfaction from food activities and testing correlations with materialism and life satisfaction.

Bio: As a PhD candidate, Robin is interested in applying Systems Science to a variety of qualitative and quantitative research techniques about sustainability and materialism. She is an avid urban gardener, enthusiastic knitter, and is working on cooking all the recipes in Julia Child's cookbook, Mastering the Art of French Cooking.

Title: Why did we invent General Systems Theory? Speculations on Human Nature (part 1)

Summary: Is the enterprise of Systems Science aimed essentially at a problem arising from Human Nature? We will say that it is.  The argument will entail the principle that "to know" is "to know the difference," and that discriminations require comparisons. Recent science has opened a new window on the question of Human Nature. We will connect those clues to the rise of philosophy, the work of Mario Bunge, and to Systems Science.

TITLE: Social, Political, and Ethical Considerations with Minority Representation in Knowledge Production

SUMMARY: Gross transgressions against minorities are in part responsible for the implementation of modern ethical research standards. However, deep issues remain embedded within the knowledge production system which can serve to reinforce marginalization and oppression. Using a discussion format and examples primarily drawn from disabilities research, this talk examines four interrelated aspects of social, political, and ethical concerns with respect to minorities in science:

1) Frames, past and present, of transgressions, paternalism, and power imbalances;

2) Relationships between knowledge and power, including questions of what constitutes "legitimate" scientific knowledge;

3) Impacts on science and policy of minority inclusion (and lack of inclusion) as participants, researchers, and reviewers;

4) Solutions via community-engaged research practices--as well as potential for these practices to generate new ethical dilemmas.

Title: "A Credible, Transparent, Turn-key Solution: what it takes to make water quality trading work"

Summary: The quality, credibility and transparency of water quality trading programs are critical. Strict standards governing the creation and use of offset credits provide assurances regulators need and the public expects to protect and enhance water quality. The Freshwater Trust has developed a transparent turn-key approach to water quality compliance that removes risk and uncertainty for facility managers, making the purchase of water quality credits a viable compliance alternative for addressing excess thermal or nutrient loads. As agencies set water quality limits for wastewater facilities, permittees need practical solutions to meet tough new requirements. Recently, conservation organizations and regulators came to an agreement on methods to calculate and quantify the temperature benefit of planting riparian trees. The Oregon Department of Environmental Quality approved these standards and protocols, clearing the way for quantified benefits from restoration actions to be registered as credits and used by permittees to comply with regulatory requirements. With regulator-approved metrics and infrastructure to track performance in place, The Freshwater Trust has developed a model that can finance all project costs on the front-end, and then sell the measured, quantified ecological benefit, or credit, to facilities to meet compliance requirements, without financial and performance risk for permittees.

Bio: Alex Johnson is Ecosystem Services Manager for The Freshwater Trust, Alex is deeply involved in the analysis, development and implementation of the first water quality trading programs in the Pacific Northwest. His economics and logistics background helps him to manage both credit-generating project supply chains and market expansion and enhancement efforts. Prior to his work with the Trust, he spent over a year of planning and building a 16-mile ‘conservation tourism’ trail on the west coast of Ecuador which involved many of the same themes of landowner recruitment and natural design inherent in restoration work, and currently functions as a ‘Payment for Ecosystem Services’ program due to conservation contracts with local property owners. Before Ecuador, he worked in refined petroleum trading and logistics for a subsidiary of Morgan Stanley in Denver, CO.

Title: "Fractals, Scaling and the Complexity of Cities"

Summary: Cities are simultaneously the physical manifestation of buildings and infrastructure or hardware as well as the software and wetware& of socio-economic systems and biological/ecological systems. Fractal cartography, cellular automata simulation, genetic algorithms and statistical physics are some of the novel tools that are being used to explore these deeply interconnected systems. The emerging science of cities is an interdisciplinary effort with that draw on disparate domains: philosophy, artificial life, agent based modeling/design, system dynamics, information theory and machine learning.

With over half the world’s population living in cities and millions more moving to them every year, an understanding of large-scale patterns occurring in cities is crucially important. The matter gains additional urgency when even larger scale phenomena such as global warming, resource depletion and human efforts at sustainability are considered.

John has been developing ‘chapters’ in an online resource called Complexity Explorer, including fractal geometry, biological scaling and the complexity of cities. This talk will include a walk-through of some of these materials.

Bio: John Driscoll is an architect and Ph.D student of Systems Science at Portland State University.

Title: "Modeling with computational probability" 

Summary: "A fresh approach to the problem of modeling risk and uncertainty, an approach without an appeal to sampling based methods, is presented, with the goal of bringing to Computational Probability the accessibility and progress recently seen with the advent and application of Computational Geometry. The approach here involves the direct computation of random variables and of certain algorithmic combinations thereof, complementary and in contrast to the sampling based methods capitalized on by the Baysians.

The direct calculation approach frequently offers considerable savings in computational resources when compared to traditional sampling based methods. In many cases, a model now having random variable(as opposed to sharp) inputs needs only be run once to obtain quality resolutions of the distributions for the now random variable (as opposed to sharp) outputs. This is in contrast to the many thousands, millions, or even billions of runs required by the more traditional Monte Carlo based methodology to obtain a similar level of resolution.

Applications include classic constrained optimization, extending, for example, linear programmatic techniques from sharp to random variable inputs with the corresponding change in outputs. Many models and stochastic processes employed in Financial Analysis, e.g. Black-Scholes Pricing, can be similarly upgraded to accept random variable inputs."

Presenter: Max Orhai

Title: Asynchronous parallel computation of cellular automata

Abstract: Cellular automata (CAs) are a broad class of discrete dynamical systems with spatial structure. Even very simple CA systems have been show to be "Turing complete" --- theoretically as powerful as any sequential computer. Their early development was roughly contemporary with that of conventional sequential computer technology, and they have proven useful for modeling a wide variety of spatially distributed parallel systems in the natural sciences. However, CAs have largely remained an abstract model, whose concrete instantiations have generally been in the form of software emulations running on sequential computers. The increasing availability of parallel forms of computation (such as multi-core and graphics processor architectures) offers new possibilities for practical uses of CAs and other forms of parallel computing --- as well as significant challenges involving timing and coordination.

In this talk I will discuss some of the issues involved in adapting CAs to practical parallel computers, and demonstrate some basic techniques for ensuring both correctness and efficient use of memory without relying on central control or strict timing guarantees.
