We examine the ways in which the research process differs in developed and developing areas by focusing on two questions: First, is collaboration associated with productivity? Second, is access to the Internet (specifically use of email), associated with reduced problems of collaboration? Recent analyses by Lee and Bozeman (2004) and Walsh and Mahoney(More)
Based on a face-to-face survey of 312 scientists from government research institutes and state universities in two Philippine locations — Los Baños, Laguna and Muñoz, Nueva Ecija — we examine how graduate training and digital factors shape the professional network of scientists at the “Global South.” Results suggest that scientists prefer face-to-face(More)
In contrast to recent US studies showing a decrease in core network size, our Kenyan data reveals substantial network growth. We attribute this to the diffusion of mobile telephones. Results from pooled survey data from Nairobi professionals and entrepreneurs in 2002 and 2007 as well as qualitative interviews from 2007 to 2009 show virtual saturation in the(More)
Mobile telephony has diffused more rapidly than any Indian technology in recent memory, yet systematic studies of its impact are rare, focusing on technological rather than social change. We employ network surveys of separate groups of Kerala residents in 2002 and again in 2007 to examine recent shifts in mobile usage patterns and social relationships.(More)
This essay is an account of use and advocacy of video ethnography as a social research method. We focus on the contemporary technology of digital video in contrast to prior methods of ethnographic data collection, using the Lower Ninth Ward of New Orleans after Hurricane Katrina to describe the capture of an infrastructural context. The importance of audio(More)
N,N-Diphenylamines were discovered as potent and selective EPAC2 inhibitors. A study was conducted to determine the structure-activity relationships in a series of inhibitors of which several compounds displayed submicromolar potencies. Selectivity over the related EPAC1 protein was also demonstrated. Computational modeling reveals an allosteric site that(More)
We explored the social shaping of science at the micro-level reality of face-to-face interaction in one of the traditional places for scientific activities-the scientific lab. We specifically examined how doctoral students' perception of their: (i) interaction with doctoral mentors (MMI) and (ii) lab social environment (LSE) influenced productivity.(More)
AIM Examine the influence of students' perception of faculty caring on academic performance and the moderating role of students' perceptions of campus racial climate. BACKGROUND There is limited knowledge on how students' perceptions of faculty caring, campus racial climate and academic performance are linked. Understanding this nexus is crucial to(More)
