Moving Telepresence Out of the Conference Room

2015-08-22

In this paper, we describe a project to create technology-rich spaces for informal collaboration that can be linked together using telepresence technologies. We discuss our approach, equipping spaces with very flexible, large, high-resolution displays and promoting their use for informal collaboration. We then present work in progress to add high quality telepresence to these systems and evaluate their use, with a special emphasis on their sustainability impacts.

Structure and Dynamics of Coauthorship, Citation, and Impact within CSCW

arXiv (Cornell University) · 2013-07-26 · 8 citations

CSCW has stabilized as an interdisciplinary venue for computer, information, cognitive, and social scientists but has also undergone significant changes in its format in recent years. This paper uses methods from social network analysis and bibliometrics to re-examine the structures of CSCW a decade after its last systematic analysis. Using data from the ACM Digital Library, we analyze changes in structures of coauthorship and citation between 1986 and 2013. Statistical models reveal significant but distinct patterns between papers and authors in how brokerage and closure in these networks affects impact as measured by citations and downloads. Specifically, impact is unduly influenced by structural position, such that ideas introduced by those in the core of the CSCW community (e.g., elite researchers) are advantaged over those introduced by peripheral participants (e.g., newcomers). This finding is examined in the context of recent changes to the CSCW conference that may have the effect of upsetting the preference for contributions from the core.

Calreticulin (CRT) from vertebrates is a calcium-binding protein present mainly in the endoplasmic reticulum (ER). There, it directs the conformation of proteins and controls calcium levels. This review will focus on several extracellular roles of Trypanosoma cruzi CRT (TcCRT) in relation to its capacity to inhibit the complement system, mediate parasite infectivity, interfere with angiogenesis and, as a possible consequence, with tumor growth. The TcCRT antiangiogenic effect parallels with the capacity of T. cruzi infection to inhibit tumor development in vivo. Thus, the TcCRT, complement, and endothelial cell interactions seem to be an evolutionary adaptation to promote prolonged parasite-host relationships.

Macro and micro pressures in data sharing

2012-08-01 · 5 citations

Despite predicted benefits of data integration in the sciences, many factors continue to limit data sharing. In this paper we argue that data practices of individual researchers represent a key bottleneck. Through an interview study across multiple fields, we show that data practices vary as a function of norms learned from senior mentors, where data sharing is more likely when supported and modeled by a lab director. Further, through an analysis of deposits to a data repository, we show that data practices are sensitive to global events, where data sharing is more likely in the face of an emergency or crisis. These results suggest that current strategies to achieve data integration, such as policy directives from federal agencies, are poorly aligned with incentives that matter to scientists. We conclude with a summary of influences that are more likely to shape data practices in the direction of greater data sharing.

Enabling Remote Participation in Research

IGI Global eBooks · 2011-01-18

This chapter uses the theoretical notion of common ground to explore remote participation in experimental research. On one hand, there is a desire to give remote participants the same views and capabilities that they would have as local participants. On the other, there are settings where experimental specimens and apparatus are large and difficult to effectively manipulate or view from a remote vantage point, and where multiple and diverse perspectives may be useful in decision making. In exploring these issues, the authors draw on two studies of researchers in the earthquake engineering community. The first, an interview study about attitudes toward teleparticipation, suggests that engineers are wary of remote participation because they fear the inability to adequately detect signs of potential failure. The second study, an observational study of researchers conducting an experiment in a centrifuge facility, illustrates that researchers adapt to the available information, and that diverse perspectives and information may be valuable in troubleshooting.

Social Participation in Health 2.0

Computer scientists are working with biomedical researchers, policy specialists, and medical practitioners to usher in a new era in healthcare. A recently convened panel of experts considered various research opportunities for technology-mediated social participation in Health 2.0.

Scheduling with package auctions

Experimental Economics · 2010-08-24 · 5 citations

Abstract In scientific collaborations, technologies have broadened access to scarce scientific and engineering resources. While broader access is often applauded, little attention has been focused on the problem of efficient and equitable resource allocation. This paper presents laboratory experiments designed to compare different allocation mechanisms for access to joint research facilities. Specifically, we study the Vickrey-Clarke-Groves (VCG) auction, a simultaneous ascending auction (the Resource Allocation Design, RAD), and a mechanism based on submitted rankings (Knapsack). Experimental results show that RAD and VCG are both more efficient than Knapsack, while Knapsack achieves a more equal distribution of resources than RAD or VCG. The findings highlight the need for systematic exploration of allocation mechanisms within collaboratories.

Towards a virtual organization for data cyberinfrastructure

2009-06-15 · 18 citations

We report on the exploratory stages of multi-university, multi-research-site, multi-year effort to investigate and compare data practices in multiple cyberinfrastructure projects and their emerging virtual organizations. Our long-term goal is to understand the data practices and data management requirements of virtual organizations and their implications for the design and development of data digital libraries. We have constructed our own virtual organization as a participant-observer approach to the research. Results to date suggest that collaborative technologies are emergent and that defining and scoping the data products of collaborations continues to be problematic.
