A query-based approach in Web search instruction: An assessment of current practice

An instruction program that covers search tools on the Web should incorporate a user's information need as the basis for teaching these tools. This article lays the theoretical groundwork for such a query-based approach, deriving its argument from the literature published in the early days of databases in libraries. A review of recent literature as well as tutorials on the Web reveals that librarians do not routinely consider a user's query in their training in the use of Web-based search tools. Other training elements are more prevalent, in particular the nature of search tools, search strategies and the evaluation of results found in a search. When training recommends a context for searching the Web, the advice tends to be of a general nature. These results suggest that librarians may not routinely be teaching queries as a strategy for selecting and using search tools on the Web. Suggestions for further research are presented to explore these findings.     

The effects of frequency of encouragement on performance during maximal exercise testing

The aim of this study was to determine the effects of frequency of verbal encouragement during maximal exercise testing. Twenty-eight participants (12 males, 16 females) aged 20.9 +/- 1.5 years (mean +/- s) performed a maximal exercise test (VO2max) on a treadmill without any verbal encouragement. The participants were matched according to their pre-test VO2max and placed into either a control group or one of three experimental groups. They performed a second exercise test (post-test) 1 week later. During the second test, the control group received no verbal encouragement; the 20 s (20E), 60 s (60E) and 180 s (180E) encouragement groups received verbal encouragement every 20, 60 and 180 s, respectively, beginning with stage 3 of the exercise test. Relative VO2max, exercise time, blood lactate concentration, respiratory exchange ratio (RER) and ratings of perceived exertion (RPE) were not significantly different from the first test to the second test for the control group without verbal encouragement and the 180E group that received infrequent encouragement. Post-test values were significantly higher than pre-test values for the 20E and 60E groups. The post-test values of the 20E group were significantly higher than their pre-test values for relative VO2max (P < 0.001), exercise time (P < 0.0001), blood lactate concentration (P < 0.05), RER (P < 0.01) and RPE (P < 0.0001); this was also the case for the 60E group for relative VO2max (P < 0.01), blood lactate concentration (P < 0.05), RER (P < 0.05) and RPE (P < 0.05). The results suggest that frequent verbal encouragement (every 20 s and 60 s in the present study) leads to significantly greater maximum effort in a treadmill test than when no encouragement is given or when the encouragement is infrequent (i.e. every 180 s).     

Entrepreneurial Academics: Developing Scientific Careers in Changing University Settings

This paper examines the impact of entrepreneurial initiatives within universities on scientific careers. Based on the career accounts of university‐based bioscientists involved in a government‐sponsored entrepreneurship training initiative, the paper explores the concept of academic entrepreneurialism. Three groups were identified in the data. First, academic entrepreneurs, who tended to be more experienced scientists and were now able to capitalise on their science. Second, those interested in technology transfer, who saw their career path taking them away from science, and finally a group of younger scientists who were trying to develop their career capital but were unsure what direction their career would take. The implications of these different groups for the management of universities and the development of knowledge are considered.     

Innovaton and Emulation: Lessons from American Universities in Selling Private Rights to Public Knowledge

American universities are purported to excel at technology transfer. This assumption, however, masks important features of American innovation. Attempts to emulate the US example must recognize the heterogeneity of its industries and institutions of higher education. Stanford University and the biomedical cluster in Boston, Massachusetts, illustrate the diversities that characterize this dynamic system.
