We investigate two fundamental research questions related to the funding of early-stage technology enterprises. First, does presentation design, and the presenting entrepreneur's passion and preparedness, influence experts' assessment of the merit and commercialization potential of an emerging firm's technology? Second, are the entrepreneur's passion and preparedness during a formal presentation associated with future technology success? We analyze twenty-two video-taped presentations to a U.S. Department of Defense technology transfer and granting consortium, and track subsequent technology success. From the data it appears that both entrepreneurial passion and presentation design does influence expert assessment of a technology, and future commercialization success can be predicted to some extent by the level of entrepreneurial passion exhibited during the presentation.  相似文献

The validity of two measures of English reading comprehension was examined across three different groups of English language learners (ELLs; 64 Portuguese, 66 Spanish and 65 Cantonese). All three groups were achieving within the average range in second grade. An exploratory principal components analysis of reading skills was carried out to determine which skills were related to two commonly used tests of reading comprehension, the Woodcock Language Proficiency Battery??s test of Passage Comprehension (WLPB-PC; Woodcock, 1991) and the Gray Oral Reading Test-4 (GORT-4; Wiederholt & Bryant, 2001). The factor solutions were different for the three language groups but showed many similarities in that the GORT-4 and WLPB-R tests of reading comprehension fell on the same factor within each group. Hierarchical regression analyses examining relationships among vocabulary, decoding and reading comprehension showed that language group membership did not significantly predict performance on either measure of reading comprehension. Differences that arose are likely due to issues with task validity and not ELL status. Limitations and future research are discussed.  相似文献

Since fall 2009, reference librarians at The George Washington University's Himmelfarb Health Sciences Library have been embedded in online classes through Blackboard within the School of Nursing and School of Medicine and Health Sciences. The authors sought to determine the types of questions asked of the librarian, with the goal of informing future interactions with distance education classes to help develop a standard "protocol" for working with this population of students. Eighty-two questions were categorized and qualitatively analyzed. The findings have prompted librarians to explore tools such as Elluminate Live!, a tool that allows librarians to provide synchronous instruction within the Blackboard environment.  相似文献

‘Framing’ refers to the journalistic act of reporting the news through core and secondary themes. Computer‐aided content analysis was used to study three newspapers’ framing of the Southeast Asian smoke‐cloud ‘haze’ of 1997–98. The newspapers tended to emphasize generally non‐confrontational frames and to downplay those that potentially were politically sensitive. They also favoured frames that were largely specific to their home countries. This finding tends to support the argument that journalism in Asia is unique, likely because of the influence of regional and national ideologies. But the findings also suggest that some aspects of the newspapers’ ‘haze’ coverage were consistent with US‐Western journalistic routines.  相似文献

Building on past research, this article argues that organizational life can be usefully construed as a series of communicative performances that are embedded and enacted in everyday discursive practices. Specifically, this research explores the sensemaking process individuals undertake when faced with the dilemma of knowing when to invent appropriate ways to respond rather than being automatically constrained by past routines. The research presents case study evidence drawn from participant observation and interviews with flight attendants from a major U.S. airline. Shown to be high in emotional and impression management, flight attendants perform a feminized role that privileges accommodation over authority and reassurance over safety that may influence their performances in emergency situations. The work ends with an evaluation of the dominant air travel performance in relation to safety and offers recommendations for facilitating communication and coordination among flight attendants and pilots.  相似文献

This article describes how librarians became involved as members of an interdisciplinary curricular team in a problem-based learning course for first- and second-year medical students. The experience illustrates how librarians can become part of a team, collaborating with medical faculty to assist in revising curricula, incorporating innovative teaching techniques, and creating effective simulated patient case scenarios. Working within an interdisciplinary collaborative team on curriculum development allows librarians to move beyond the traditional role of instruction and can lead to additional opportunities, including research and ongoing involvement in curricular changes.  相似文献

Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.  相似文献
