Mapping Interactions Within the Evolving Science of Science and Innovation Policy Community

The Science of Science & Innovation Policy (SciSIP) program at the National Science Foundation (NSF) supports research designed to advance the scientific basis of science and innovation policy. The program was established at NSF in 2005 in response to a call from Dr. John Marburger III, then science advisor to the U.S. President, for a “science” of science policy. It has co-funded 162 awards that aim to develop, improve and expand models, analytical tools, data and metrics that can be directly applied in the science policy decision making process. The long-term goals of the SciSIP program are to provide a scientifically rigorous and quantitative basis for science policy and to establish an international community of practice. The program has an active listserv that, as of January 2011, has almost 700 members from academia, government, and industry.

This talk will summarize a recent study that analyzed all SciSIP awards made so far in an attempt to identify existing collaboration networks and co-funding relations between SciSIP and other areas of science. In addition, listserv messages were downloaded and analyzed to derive complementary discourse information. Key results include evidence of rich diversity in communication and funding networks and effective strategies for interlinking researcher and science policy makers, prompting discussion, and resource sharing.

Plug-and-Play Macroscopes

Abstract:  This talk opens with a discussion of major changes in the landscape of science that pose challenges and opportunities for the design of effective data analysis and visualization tools. We then present a set of desirable features for designing plug-and-play "macroscope" tools and review related work. Next, we explain the design of a software architecture that extends the Open Services Gateway Initiative Framework (OSGi) and uses the Cyberinfrastructure Shell (CIShell) (http://cishell.org) to support the easy integration of new and existing algorithms and their synergistic combination. The OSGi/CIShell software framework is at the core of five plug-and-play tools that serve different scientific communities: the IVC was developed for research end education in information visualization; the Network Workbench (NWB) tool was designed for large-scale network analysis, modeling, and visualization; the Science of Science (Sci2) tool is used by science of science (policy) researchers; the EpiC tool is under development for use by epidemiologists; and TEXTrend supports the analysis of text. We present two of these tools in detail: the NWB tool (http://nwb.cns.iu.edu) and the Sci2 Tool (http://sci2.cns.iu.edu). The talk concludes with a discussion of related efforts and an outlook into the not-too-distant future.

materials iconBuilding Networks of Action Situations for the Analysis of Policy Processes and Institutions

Abstract: Within the Institutional Analysis and Development (IAD) framework, the concept of an action situation generalizes a game to allow for endogenous changes in its rules. This paper re-visits this core concept to explore its potential for serving as the foundation for a systematic approach to the construction of more elaborate models of complex policy networks in which overlapping sets of actors have the ability to influence the rules under which their strategic interactions take place. Networks of adjacent action situations can be built on the basis of the seven distinct types of rules that define an action situation or by representing generic governance tasks identified in related research on local public economies. The potential of this extension of the IAD framework is demonstrated with simplified network representations of three diverse policy areas (Maine lobster fisheries, international development assistance, and the contribution of faith-based organizations to U.S. welfare policy). See also Michael D. McGinnis. 2011. “Networks of Adjacent Action Situations in Polycentric Governance,” Policy Studies Journal 39 (1) (March 2011), 45-72.

materials iconmaterials iconModeling Social Contagion in Networks

Abstract: Social networks have introduced novel challenges in statistical modeling, and therefore novel pitfalls. We illustrate this by using a series of recent highly touted papers by Christakis and Fowler that claim to have demonstrated the existence of transmission via social networks of various personal characteristics, including obesity, smoking cessation, happiness, and loneliness.  Those papers also assert that such influence extends to three degrees of separation in social networks. However, their statistical methodology is seriously flawed at many levels, as we explain.

materials iconmaterials iconThe Trouble with House Elves: Challenges for a Computational Folkloristics

Abstract: Folklore collections are generally indexed according to the dictum, "one story, one classifier." This approach to collection indexing was generally serviceable as long as the research questions aligned with indexing practices, and as long as the collections were relatively small. As research questions changed and collections became much larger--including stories from thousands or tens of thousands of storytellers, and constituting tens of thousands of pages or hours of recording--these simple finding-aids were revealed to be inadequate for addressing even the simplest needs of researchers. Using a 19th century collection of Danish folklore, we explore the use of network analysis tools for search and discovery. We show how a tuned Markov Clustering (MCL) algorythm can be (a) used to discover stories needed to address research questions not considered by the initial indexing scheme and (b) find previously unrecognized affinities among stories that can lead to new research questions. A second part of the presentation focuses on how to visualize geographic relations between individuals and their story repertoires. The audience is reminded not to present clothing to the house elf accompanying the lecturer. 

Bio: Timothy R. Tangherlini teaches folklore, literature and cultural studies at the University of California, where he is a professor in Scandinavian Section, and the Department of Asian Languages and Cultures. He is the author of Interpreting Legend: Danish Storytellers and their Repertoires (1994), Talking Trauma. Paramedics and Their Stories (1998), and the co-editor of Nationalism and the Construction of Korean Identity (1999), and Sitings. Critical Approaches to Korean Geography (2008). He has also produced or co-produced two documentary films, Talking Trauma: Storytelling Among Paramedics (1994) and Our Nation. A Korean Punk Rock Community (2002). His current work focuses on computation and the humanities. In particular, he has focused on using GIS to discover patterns in folklore collections, and network analysis techniques to address problems of classification.

materials iconmaterials iconText Classification of the Biomedical Literature

Abstract: Much of the research presently conducted in the biomedical domain relies on the induction of correlations and interactions from data. Because we ultimately want to increase our knowledge of the biochemical and functional roles of genes and proteins in organisms, there is a clear need to integrate the associations and interactions among biological entities that have been reported and accumulate in the literature and databases. Biomedical literature mining is an important informatics methodology for large scale information extraction from repositories of textual documents, as well as for integrating information available in various domain-specific databases and ontologies, ultimately leading to knowledge discovery. It helps us tap into the biomedical collective knowledge, and uncover relationships and interactions buried in the literature and databases, and even those inferred from global information but unreported in individual experiments. Our approach to literature mining is based on bottom-up, data-driven or bio-inspired methods, which we have applied to automatic discovery, classification and annotation of protein-protein and gene-disease interactions, pharmacokinetic data, protein sequence family and structure prediction, functional annotation of transcription data, enzyme annotation publications, and so on. In this talk I will focus on the lightweight Variable Trigonometric Threshold (VTT) linear classifier we developed for biomedical text classification, and which we have applied successfully to the protein-protein interaction literature. The latest version of this method utilizes a number of features obtained via Named Entity Recognition (NER) and dictionary tools. We will discuss our results with this classifier in the recent BioCreative challenges where it has performed very well. We will also contrast this method with ongoing research in our group to develop biologically-inspired methods for biomedical text classification.

materials iconmaterials iconInformatics for science-based groundwater management and socio-technical interfaces

Abstract: The field of Integrated Water Resource Management (IWRM) engages groups to explore collaborative decision making with the use of simulation-optimization models and decision support systems. Of particular interest is the implementation of IWRM approaches to groundwater systems. Groundwater, which makes up 98% of total available freshwater on Earth, is notably absent in formal education curricula and public communication about water resource availability. The result is a public that is unacquainted with one of society’s most precious resources. Melding informatics with collaborative modeling, poses opportunities to educate an informed citizenry with the capacity to visually explore complex scientific topics and participate in substantive dialogue. This work presents results of topical analysis using management and policy texts as compared with modeled outputs from a Groundwater Decision Support System (GWDSS). A conceptual meta-model, or schema, has been developed to overlay policy objectives with feasible sets of groundwater response. The resultant network presents an interface with the capacity to span knowledge domains between planning contexts and scientific computation. Informatics visualizations provide a socio-technical interface to activate generative dialog and catalyze science-based deliberation.

Bio: Suzanne A. Pierce is a Research Assistant Professor with the Center for International Energy and Environmental Policy in the Jackson School of Geosciences and Assistant Director of the Digital Media Collaboratory in the Center for Agile Technology at The University of Texas at Austin. A trained hydrogeologist with a focus on participatory deliberation, Dr. Pierce has prior professional background as a Scientist with Sandia National Laboratories and as the Environmental Manager for one of the world’s largest metals mines. Dr. Pierce adopts a scholar-practitioner approach to integrate science-based information with human organizational systems for application to groundwater management and energy-water problems. Resultant decision support systems link participatory modeling with simulation, optimization, and multi-stakeholder concerns. Current projects include development of hydroinformatics for sustainable aquifer yield in Central Texas and South Australia, along with evaluating perceptions of science at a geothermal basin in the Atacama Desert of Chile.

materials iconmaterials iconMapping Evaluation Models and Plans: Evaluation Protocols and Pathways

Abstract: Evaluations of programs and policies don’t occur in isolation. They are typically embedded in hierarchical systems of organizations (funders, administrative management, program management, program delivery) and the networks of models that guide evaluations can be usefully construed as interconnected conceptual systems encompassing program logic, research literature and evidence, measurement alternatives, etc. Increasingly the field of evaluation has been exploring systems approaches (evolutionary and ecological theories, network analysis, conceptual mapping, causal pathway modeling, etc.)  to organize and represent evaluation models and plans and to network programs and people so they can more effectively function as a collective learning community. This talk presents work being conducted under an NSF grant to develop a general protocol for planning, implementing and utilizing an evaluation that connects such an effort to a broader ecosystem of evaluations. A key component of this work is the development of a complementary web-based cyberinfrastructure called the Netway that connects or networks causal pathway models from separate evaluations and enables identification of and communication between programs that share model features and evaluation needs. The evaluation protocol is briefly introduced, along with some of the systems thinking that is central to it. Then the Netway cyberinfrastructure is presented and some of the major challenges in designing it are introduced. In the general discussion, we hope to consider some of the possible directions that development of this approach and technology might take.

Bio: William Trochim is Professor of Policy Analysis and Management at Cornell University and Professor of Public Health at the Weill Cornell Medical Center. He is the Director of Evaluation for the Weill Cornell Clinical and Translational Science Center, the Director of Evaluation for Extension and Outreach at Cornell, and the Director of the Cornell Office for Research on Evaluation.  His research focuses on the development and assessment of evaluation and research methods and their use for managing and enhancing science and biomedical research in the twenty-first century. Dr. Trochim has developed quasi-experimental alternatives to randomized experimental designs, including the regression discontinuity and regression point displacement designs.  He created a structured conceptual modeling approach that integrates participatory group process with multivariate statistical methods to generate concept maps and models useful for theory development, planning and evaluation. He has published widely in the areas of applied research methods and evaluation including the books: Research Design for Program Evaluation:  The Regression-Discontinuity Approach (1984), Concept Mapping for Planning and Evaluation (2005), Research Methods: The Concise Knowledge Base (2005), and the Research Methods Knowledge Base (2007). Dr. Trochim is currently conducting research with the National Institutes of Health on the evaluation of biomedical clinical and translational research and with the National Science Foundation on evaluating science, technology, engineering and mathematics (STEM) education programs. Dr. Trochim served for four years on the American Evaluation Association’s Board of Directors, was the chair of several AEA committees (electronic communications, public affairs), and was President of AEA (2008).

materials iconmaterials iconThe Role of Social Networks and Boundary Spanning Organizations in Highly Innovative Communities

Abstract: Until very recently, few paid attention to the extent to which the social dynamics and cultural “grooves” of specific communities enabled or inhibited their capacity to recognize changing economic imperatives, integrate new knowledge into their understanding of their economic horizons, and develop effective strategies to renew or transform their economies. Emerging research on social networks and boundary spanning organizations suggests they are vital to the ability of communities to successfully build more nimble and innovative approaches to economic growth and job creation.

Bio: Mary Lindenstein Walshok, Ph.D., a sociologist, is Associate Vice Chancellor and Dean of the Extension Division at the University of California, San Diego. Over three decades, she has been a catalyst in building regional collaborations focused on high-tech cluster development (UCSD CONNECT) and cross-border synergies (the San Diego Dialogue) based on San Diego’s proximity to Mexico. She is the author of four books: Blue Collar Women, Knowledge Without Boundaries, Closing America’s Job Gap and Invention and Reinvention: The Evolution of San Diego’s Innovation Economy, forthcoming in StanfordUniversity Press. She has also authored more than 100 reports and articles on the regional competencies and social dynamics essential to building knowledge-based clusters and high-wage jobs. Walshok’s current research activities include serving as the Principal Investigator for the evaluation of 13 Generation I WIRED regions funded by the U.S. Department of Labor; a two-year NSF-funded project comparing the distinctive social dynamics of three innovation regions – Philadelphia, St. Louis, and San Diego; and a Lilly Foundation-funded assessment of efforts to sustain and grow the robust orthopedic device industry in Warsaw, Indiana.
Walshok is the recipient of numerous awards including the distinguished Kellogg Foundation’s Leadership Fellowship and, most recently, induction into Sweden's Royal Order of the Polar Star. Active on boards of a number of arts and philanthropic organizations, Walshok chaired the boards of the San Diego Community Foundation during 2002-2004 and the International Community Foundation during 2007-2009. She is currently serving on the boards of the San Diego CONNECT, the La Jolla Playhouse, the United States-Mexico Foundation for Science, International Community Foundation, and the Girard Foundation.
