The paper experiments with, and reflects on, the limited possibilities for collaboration and communication across disparate groups within the university setting. The authors respond to the strong imperative to bring management, academics and support staff together, and so move beyond the entrenched positions and interests that those groups often display. They highlight the implications that this may have for collaborative academic publication. The text of the paper works as a research exercise in which each author's contribution constitutes data as well as providing reflections upon their own distinct identity and its consequences for communication in universities. The authors argue that attempts to enact ‘better communication’ is in many senses a failed project, but that it is this very fact which makes the experiment instructive. They conclude that calls to collaboration must acknowledge the fact that such relationships will always be relations of power, and are therefore not easily negotiated or understood. 相似文献

Libraries are adding electronic resources of all kinds at an increasing pace to provide service to users outside the library and around the world. To meet this new demand, libraries are turning more and more to the use of online tutorials as a valuable means of providing instruction on how to access and use important resources. This article describes the Health Sciences Library and Biocommunications Center's work and experiences while creating tutorials, the ideas used, and ways the work was evaluated. 相似文献

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M = 39.96 mL x kg(-1) x min(-1), SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL x kg(-1) x min(-1), % SEE = 8.62): VO2max (mL x kg(-1) x min(-1)) = 48.0730 + (6.1779 x gender; women = 0, men = 1) - (0. 2463 x age) - (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R(p) = .91 and SEE(p) = 3.63 mL x kg(-1) x min(-1)); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18-65 years) with a similar cardiorespiratory fitness level. Based on standardized beta-weights, the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women. 相似文献

The sucrose preferences of two prosimian primate species, slow loris and greater galago, were determined under aperiodic reinforcement of a free operant. Stimuli were solutions of the following concentrations: 5%, 10%, 20%, 30%, and 40%. Solutions of intermediate concentration were preferred, and thus the function relating barpresses to concentrations was nonmonotonic. 相似文献
