NARCIS consists of two databases: (1) An aggregation of the metadata of all open access publications and datasets within Dutch scholarly repositories and (2) the Dutch Research Information System with information about institutions, projects, and expertise of researchers employed at Dutch research institutions [1]. Using a dump of the NARCIS Dutch Research Information System made on April 3, 2012, we extracted the bi-partite network of 14 Dutch universities and their 8,156 full and assistant professors. Professors with only one affiliation appear in a dandelion pattern around their respective university, their multitude indicating the size of the university. The University of Amsterdam (Node 2) has 932 affiliated professors and is the largest university in The Netherlands. There are 265 professors with multiple university affiliations that interlink the Dutch universities to one national network also on the institutional level. Please be aware that through co-authorship and project collaboration the network between universities is much more intensive. This talk will also discuss alternative analyses of this dataset. http://www.slis.indiana.edu/media/net_sci_2012/ncs_10_22.mp3 Thu, 01 Nov 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/kaser/kaser12_dempsey.mov - Kaser Lecture 2012 (video): I borrow part of my title from words used by John Hagel and colleagues to talk about the challenges facing organizations in a reconfigured network environment. My talk will focus on how the network has changed the way libraries need to think about what they do and how they position themselves at an organizational level, rather than at the level of individual services. Indiana University has been a pioneer in thinking about scalable efficiency as it has looked at multi-institutional solutions (Hathi Trust, Sakai, ...). Increasingly, research libraries will look at collaborative ways of sourcing local infrastructure as institutional attention shifts to deeper engagement with changing research and learning behaviors on campus. But what forms does such engagement take? And as libraries participate more fully in the processes of research and learning how will they be adaptive and responsive, becoming organizations that can scale the learning and innovation that is required to keep pace with changes in the scholarly environment? http://www.slis.indiana.edu/media/kaser/kaser12_dempsey.mov Mon, 22 Oct 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2012/ncs_10_08.mp3 - Fall 2012 Talk Series on Networks and Complex Systems (audio): Genius is attributed to people who create new paradigms, new ways of seeing. Examples include Newton, Einstein, Picasso, Beethoven, and Pasteur. Teams bring together a group of people with knowledge, experience, and skill to tackle problems. Where are the genius teams? Creative knowledge work depends on sharing questions, ideas, and experiences. In the sharing process, knowledge flows from one person to another through a variety of channels that includes interpersonal communications, archived information such as books, and modern cyberinfrastructure. Each of these channels enhances or restricts flow in a variety of ways. Constructal theory suggests that the channels naturally evolve to handle more capacity and minimize resistance to flow. The more complex the problem, the more knowledge must be brought to bear, so flow becomes crucial. Project team creativity depends on flow capacity in each type of channel. That capacity approaches optimal levels only when complex structure has evolved in the team and fits the environment. With optimal flow, knowledge can grow, and perhaps team genius will emerge. http://www.slis.indiana.edu/media/net_sci_2012/ncs_10_08.mp3 Mon, 15 Oct 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2012/ncs_10_01.mp3 - Fall 2012 Talk Series on Networks and Complex Systems (audio): This hands-on session provides an introduction to a widely used network visualization tool http://www.slis.indiana.edu/media/net_sci_2012/ncs_10_01.mp3 Mon, 08 Oct 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2012/ncs_09_24.mp3 - Fall 2012 Talk Series on Networks and Complex Systems Talk (audio): A translational bioinformatics spectrum will be introduced for the drug interaction research.

As these artifacts diffuse throughout the institutional fabric, their attributes and the operations that they sustain install themselves at the heart of social practice, challenging important canons and traditions in which stable, bounded, and recognizable objects have figured prominently. These ideas are illustrated with reference to 1) provenance and authenticity of digital documents in the overall context of archiving and social memory and 2) the content dynamics associated with Internet search engines. While variously observed in information systems research, the implications of the distinct ontology of information-based artifacts that we refer to as digital objects have not yet been adequately theorized or empirically explored. We argue that the study of digital objects opens up a new frontier for IS research. http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_4_27_12.mov Wed, 23 May 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_4_6_12.mov - RKCSI Speaker Series (video): The term white-collar crime has its historical roots in Indiana University and to the late Professor Edwin Sutherland. Sutherland’s introduction of the term has been both a blessing and a curse. It has been a blessing for it called attention to a variety of crimes which were and remain to this day widely neglected. It has been a curse because the term is both a conceptual and definitional quagmire. The result is that although we know quite a bit about the frequency and correlates of conventional “street crimes,” we know virtually nothing about “suite crimes,” or those offenses committed in the context of legitimate occupational activities and markets. The aim of the presentation is to discuss the origins of the term, white-collar crime, situate it in the context of current technological advancements, and examine the conceptual and empirical challenges in developing reliable information sources from which we derive both our common understanding of the problem and our systems of social control http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_4_6_12.mov Tue, 22 May 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_3_23_2012.mov - RKCSI Spring Speaker Series (video): The recent withdrawal of two bills before Congress designed to prevent the illegal hosting of copyrighted content by companies operating outside the United States provides an important example of the power of Internet-based political campaigns that are backed by large numbers of Internet users. The bills were backed primarily by content-owning firms in the film and recording industries who were looking for new ways to prevent the illegal use (which they call piracy) of their intellectual property via digital file sharing. It looked at first that the bills would sail through Congress with little opposition. But it turned out that a well-organized campaign by a wide variety of interests opposed to the legislation was successful to the surprise of many observers. This talk explores the origins of the controversy and attempts to explain the outcome. http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_3_23_2012.mov Thu, 26 Apr 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_2_24_2012.mov - RKCSI Spring Speaker Series (video): Emerging research on the role of media in social and political unrest in North Africa and the Middle East reminds us that newer networked media tools, like Facebook, Twitter, YouTube, and the mobile Web, are not inherently transformative. What matters is how people select and use these tools and in what cultural contexts. However, this does not mean that a search for generalizable patterns of transformation is futile. In this talk, I discuss a work-in-progress that explores how activists in the Central Asian country of Kyrgyzstan use newer networked media tactically. I begin by drawing on my past work in Kyrgyzstan and on more recent research to discuss how newer media have opened up opportunities for alternative forms of expression, participation, and learning in Kyrgyzstan. I then discuss and seek feedback on a study I am designing that investigates an information technology activist culture and its influence in Kyrgyzstan. Considerable evidence suggests that this small group may be playing a role in spreading awareness and in connecting otherwise separate domestic and international people that can lead to new ideas, new identities, and new opportunities for group actions, as well as new tensions and entrenchment. Finally, I suggest that this small group of IT activists may be filling an information and community-building void left by the increasingly irrelevant news media in Kyrgyzstan http://www.slis.indiana.edu/media/rkcsi_2012/rkcsi_2_24_2012.mov Mon, 19 Mar 2012 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_12_05.mp3 - Networks and Complex Systems Talk (audio): The spatial turn in the humanities has been heavily premised on the use of GIS and geospatial technologies in project-based applications. This focus on GIS has come to the humanities after having made much earlier and successful inroads into the sciences and social sciences, not least because its algorithmic and positivist scientific architecture would initially appear to be at odds with the predominantly text-based and qualitative world of the humanities. Yet the humanities, far from being the recipients of a colonizing technology, have the potential to assimilate, shape, and refashion the technology to suit the somewhat unique characteristics of its own methodological traditions. This presentation explores the assumptions inherent in the adoption of a spatial scientific methodology and proposes ways in which the broader science of geographic information may be appropriately harnessed in the spatial humanities. http://www.slis.indiana.edu/media/net_sci_2011/ncs_12_05.mp3 Thu, 22 Dec 2011 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_11_21.mp3 - Networks and Complex Systems Talk (audio): We discuss general theory behind deterministic annealing and illustrate with applications to mixture models (including GTM and PLSI), clustering and dimension reduction.

Specifically, Project Risk Assessment for Mexican Americans (RAMA) investigated the impact of Family health history (FHH)-based risk feedback on the risk communication and screening encouragement pathways in families of Mexican origin. All 465 participants from 161 households received a FHH pedigree. Households were randomized to one of four feedback conditions defined by two factors: 1) all or one participating household member received supplemental, personalized FHH-based risk assessments and 2) whether or not behavioral recommendations accompanied these personalized risk assessments. Personalized risk assessments and behavioral recommendations for heart disease and diabetes were generated using the CDC's Family Healthware. Outcomes included enumerated family members with whom participants shared feedback and discussed family risk of heart disease and diabetes at 3-month follow-up and from whom they received encouragement to engage in risk reducing behaviors at 10-month follow-up. Participants from households in which all members received supplemental RAs were more likely to initiate new communication pathways regarding family risk of heart disease, but not diabetes, at 3-month follow-up. At 10-month follow-up, participants from households in which everyone received a RA and behavioral recommendations were more likely to enumerate new encouragers of blood pressure and blood glucose testing. With respect to encouragement of lifestyle factors, participants in households in which all members received supplemental RAs were more likely to enumerate new encouragers of increased fruit and vegetable consumption at 10-month follow-up, while provision of behavioral recommendations improved encouragement for maintaining a healthy weight. Results suggest that a family-centered FHH-based feedback approach was more effective than an individual level approach in activating risk communication and behavioral encouragement pathways within family network systems. Next steps will examine how these social processes influence health behavior. http://www.slis.indiana.edu/media/net_sci_2011/ncs_11_14.mp3 Wed, 30 Nov 2011 00:00:00 -0500 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_10_24.mp3 - Networks and Complex Systems Talk (audio): We present insights from analyzing the eigenvalues of the adjacency, normalized Laplacian, unnormalized Laplacian, and modularity matrices of a range of real-world graph and network models. This includes finding complete spectra for graphs with hundreds of thousands of nodes.

Each of these photos is an observation of what a small part of the world looked like at a particular point in time and space, as well as a record of where its photographer was and what he or she was paying attention to. When aggregated together and combined with the non-visual metadata available on photo sharing sites (including timestamps, geo-tags, and captions), these billions of photos are a rich source of information about the world and about human activity. In this talk I'll discuss some of our recent work in data mining and computer vision that aims to unlock this latent information from photo-sharing sites. In particular, I'll focus on two recent lines of work: reconstructing maps and 3-d models of the world from online photos, and studying how patterns of human travel are correlated with (and predictive of) social connections. http://www.slis.indiana.edu/media/net_sci_2011/ncs_10_10.mp3 Mon, 17 Oct 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2011/rkcsi_01_14.mov - The Rob Kling Center for Social Informatics Speaker Series (video): Scientific studies of information/computer security have been going on now since the early days of computers. In the earliest period (roughly 1954-1980), most studies were concerned with the IT artifact itself, how to build systems so there was an inviolable security kernel. Cryptography fit neatly into this general interest and encryption algorithms became a small industry. Interest in behavioral issues lagged and even today represents only a fraction of the intellectual fervor in technical issues that has dominated the academy. How would one go about enhancing our understanding of how and why black hats attack systems and the effectiveness of the responses of the white hat protectors? We review a few recent research publications to identify gaps in the literature and discuss why we need to change and improve our data about this critical phenomenon. There is certainly a need to design and create new IT security artifacts, and intriguing new approaches are outlined in this domain, but these overall gaps in research call out for new studies of hackers and anti-social terrorists. http://www.slis.indiana.edu/media/rkcsi_2011/rkcsi_01_14.mov Thu, 07 Jul 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/rkcsi_2011/rkcsi_04_15.mov - The Rob Kling Center for Social Informatics Speaker Series (video): This paper outlines a set of guidelines for conducting a functional Magnetic Resonance Imaging (fMRI) study in IS research. Given the increased interest in using neuroimaging tools in the IS discipline, this study aims at specifying the key steps needed to conduct an fMRI study and ensure that enough detail is provided to evaluate the methods and results. The outline of an fMRI study consists of four key steps: (1) formulating the research question, (2) designing the fMRI protocol, (3) analyzing fMRI data, and (4) presenting and interpreting fMRI results. The fMRI study is illustrated with a comparative study between self-reported measures of two primary dimensions of trust (credibility and benevolence) and of distrust (discredibility and malevolence) with the corresponding brain activations while subjects responded to psychometric measures of trust and distrust while their brain activity was measured in an fMRI scanner. The results show that the correlations between the behavioral and the corresponding brain activations are lower for the more emotional (affective) areas of the brain than the more cognitive (calculative) areas. Besides, the correlations are higher in women than in men for the more emotional brain areas, while they are higher in men than women in the more cognitive areas. Finally, the levels of brain activations have a higher predictive power on a common dependent variable (price premium) than the self-reported data, particularly the women’s brain activations that helped explain a higher degree of the variance than men. The paper contributes to the literature by (a) providing a set of guidelines for designing and conducting fMRI studies in IS research, (b) specifying methodological details that must be included in fMRI studies in IS journals, and (c) illustrating these practices with a comparative study between behavioral and brain data for two IS constructs across genders. Implications for designing high-quality fMRI studies in IS research and for the descriptive and predictive validity of psychometric and brain data are discussed. http://www.slis.indiana.edu/media/rkcsi_2011/rkcsi_04_15.mov Wed, 25 May 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_03_28.mp3 - Networks and Complex Systems Talk (audio): 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. http://www.slis.indiana.edu/media/net_sci_2011/ncs_03_28.mp3 Fri, 06 May 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_04_18.mp3 - Networks and Complex Systems Talk (audio): 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.

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. http://www.slis.indiana.edu/media/net_sci_2011/ncs_04_11.mp3 Mon, 18 Apr 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_04_04.mp3 - Networks and Complex Systems Talk (audio): This talk will explore the use of academic genealogy networks to explore the formation, maturation, and intersection of disciplines.

We will then analyze the potential relationship between these perceptions and respondents’ exposure to various types of news. While the analysis of our data is not complete, we expect to find that respondents with more exposure to news about China have a more positive image of China and the Chinese people in general. http://www.slis.indiana.edu/media/rkcsi_2011/rkcsi_03_24.mov Mon, 04 Apr 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_03_21.mp3 - Networks and Complex Systems Talk (audio): Brief Presentations and Panel with: Kevin W.

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. http://www.slis.indiana.edu/media/net_sci_2011/ncs_03_07.mp3 Mon, 21 Mar 2011 00:00:00 -0400 no School of Library and Information Science, Indiana University, information architecture, Information Science, information systems, information technology, library science, librarian, library school, information retrieval School of Library and Information Science http://www.slis.indiana.edu/media/net_sci_2011/ncs_02_28.mp3 - Networks and Complex Systems Talk (audio): 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.
