Research suggests that media images depicting aggression against sexually objectified women may promote hostile sexism in men. We empirically tested if such effects might occur when men commit simulated acts of aggression against sexualized female opponents in video games, and if such effects might be heightened by psychological immersion (i.e,. the sensation of “presence” while gaming). In two studies, male participants played a first-person-shooter game, with the sex and sexualization of opponents experimentally manipulated. Results indicated that game play increased hostile sexism, to the extent that players reported feeling present in the virtual environment and provided that opponents were depicted as sexualized females, not males or nonsexualized females. No effects on benevolent sexism were observed. These results suggest that the increasingly immersive nature of modern video games might amplify their influence on players, including effects that promote hostility and aggression towards women. 相似文献

In the studies reported here, we investigate the effects of context on students’ molecular‐level ideas regarding aqueous solutions. During one‐on‐one interviews, 19 general chemistry students recruited from a two‐year community college and a research university in the United States were asked to describe their molecular‐level ideas about various aqueous solutions in the contexts of conductivity and boiling‐point (BP) elevation. Results indicate that context is important for determining the molecular‐level ideas that students express. Specifically, students were significantly more likely to draw pictures of aqueous NaCl as separated ions in the conductivity context compared with the BP elevation context, for which they more often drew “molecular” NaCl. This phenomenon was particularly striking because the students drew molecular‐level NaCl(aq) pictures in the BP elevation context just minutes after completing the identical task in the context of conductivity. Additional data from laboratory assignments and course examinations further indicate that, even if students are able to correctly represent the molecular level in some contexts, their knowledge may remain inert in slightly different contexts. The results emphasise the importance of the context dependence of molecular‐level ideas and have implications for designing instruction in which students develop robust, coherent understandings that they can apply appropriately in new contexts. 相似文献

The Australian Research Council's Network for Early European Research (NEER) is a recent initiative aimed at broadening and deepening research in the field of medieval and early modern European studies. An integral part of the Network is its Digital Services Programme, which integrates a range of digital strategies designed to advance the Network's goals. Among these strategies is a project to develop a national discipline-based digital repository known as PioNEER. This paper looks at the issues that have arisen in the course of this project. 相似文献

OBJECTIVE: To evaluate the adequacy of the MEDLINE instruction routinely given to all entering medical students at the University of Miami School of Medicine and the ability of students to search effectively for and retrieve evidence-based information for clinical decision making by the end of their third-year. METHODOLOGY: The authors developed and implemented a strategy for evaluating the search strategies and articles selected by third-year students, who participated in the Objective Structured Clinical Examination (OSCE) in June 1996, 1997, and 1998, and reviewed the literature on evidence-based medicine and evaluation of medical student searches. RESULTS: A mean of 5% of the students' search strategies and a mean of 26% of articles selected were ranked "excellent" or "good"; a mean of 26% of search strategies were ranked "fair" and a mean of 69% were ranked "poor"; and a mean of 22% of articles selected were ranked "fair" and a mean of 52% were ranked "poor" based on the strategy developed to evaluate student searches. CONCLUSIONS: Evaluating medical student searches for evidence-based information is an effective way of evaluating students' searching proficiency, and, in turn, the adequacy of the instruction they receive. Based on the results of the OSCE test, the school of medicine expanded the library's educational role and the library implemented major changes in the training program. Information on evidence-based medicine is now incorporated into the MEDLINE instruction. Library faculty evaluate the required searches performed by students for evidence-based information during their first and second years; 30% of students are identified for follow-up, individualized instruction based on the evaluation; and a new case-based curriculum has been proposed with a fourteen-week problem-based learning (PBL) block. These developments are timely in light of the evidence-based competencies recently published by the Association of American Medical Colleges. 相似文献

Twenty highly trained, eumenorrhoeic female endurance runners were studied over three consecutive menstrual cycles. Average training distance per week, total years training and mood states were recorded throughout the three cycles. Salivary progesterone and menstrual cycle diaries were recorded over the first two cycles to identify luteal phase onset and the presence of any menstrual irregularities. Saliva samples were collected daily over the third cycle for analysis of immunoglobulin A (IgA) concentration and secretion and saliva flow rate. Two-way analysis of variance (ANOVA) revealed no significant differences in mood states across the phases of the menstrual cycle (P > 0.05). Training logs indicated that training did not alter throughout the 3 month study. One-way ANOVA revealed no significant differences in IgA concentration (P = 0.92), secretion rate (P = 0.84) or saliva flow rate (P = 0.95) across the phases of the menstrual cycle. Pearson's product-moment correlation revealed no relationship between IgA concentration and progesterone between the phases of the cycle (r = 0.39). We conclude that, in ovulatory female endurance runners whose physical and emotional stress are stable, IgA concentration is not significantly affected by fluctuations in progesterone during the menstrual cycle. 相似文献

The purpose of the present study was to assess the effectiveness of the triad components (amenorrhoea, disordered eating, and osteoporosis) in identifying physically active women at risk of long-term health problems. Eighty-two females (mean age 31.1 years, s = 6.7; body mass 58.4 kg, s = 6.6; stature 1.65 m, s = 0.06) completed training, menstrual, and dietary questionnaires. Bone mineral density and size-adjusted bone mineral density were assessed at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. Seventy-eight percent of participants were eumenorrhoeic, 20% were oligomenorrhoeic, and 2% were amenorrhoeic. Thirty-six percent and 55% reported disordered eating practices in the present and past respectively. Eighty-one percent, 17%, and 2% were classified as normal, osteopaenic, and osteoporotic at the femoral neck respectively; 92% were normal, 7% osteopaenic, and 1% osteoporotic at the lumbar spine. No significant differences in femoral neck size-adjusted bone mineral density were observed between eumenorrhoeic and oligo/amenorrhoeic participants (F(2,80) = 0.119, P = 0.73); eumenorrhoeic participants had significantly greater lumbar spine size-adjusted bone mineral density (F(2,80) = 9.79, P = 0.003). Disordered eating participants had significantly lower femoral neck size-adjusted bone mineral density than those reporting no disordered eating (F(2,80) = 13.816, P = 0.000). Twenty-two percent of participants fulfilled triad criteria, while 55% were "at risk" of long-term health problems. An accumulation of conditions resulted in lower lumbar spine size-adjusted bone mineral density (F(1,80) = 6.074, P = 0.004). The current triad components do not identify all women "at risk" and more appropriate criteria such as exercise-related menstrual alterations, disordered eating, and osteopaenia are suggested. 相似文献

This paper critically examines the assumptions about 'childhood' and 'child development' that inform curriculum construction in school physical education. Drawing on insights from poststructuralist social theory and critical psychological perspectives, the paper argues that developmental discourses have a material life embodied in the institutional practices of school physical education. A New Zealand physical education syllabus is used as an illustrative exemplar of the ways in which developmental imperatives shape the construction of learning goals, design of curriculum experiences and teachers' observations of their students. It is argued that the construction of a normative, hierarchical trajectory for child development categorises, classifies and marginalises groups of children whose developmental patterns differ from those mapped out in the syllabus. The paper concludes by examining the conditions of possibility present in more contemporary physical education syllabi and theory that afford opportunities for thinking about physically educated children differently. 相似文献

A comparison of the MEDLARS data base as it is currently available from the National Library of Medicine and Bibliographic Retrieval Services (BRS), Inc., is presented in chart format, and some major capability differences between the two systems are highlighted. The information inlcuded justifies the dual availability of the data base in health sciences libraries. This paper is intended for searchers and others familiar with one or both systems. Administrators considering the acquisition of the BRS system may find the study useful. 相似文献

The Internet has created new opportunities for librarians to develop information systems that are readily accessible at the point of care. This paper describes the multiyear process used to justify, fund, design, develop, promote, and evaluate a rehabilitation prototype of a point-of-care, team-based information system (PoinTIS) and train health care providers to use this prototype for their spinal cord injury and traumatic brain injury patient care and education activities. PoinTIS is a successful model for librarians in the twenty-first century to serve as publishers of information created or used by their parent organizations and to respond to the opportunities for information dissemination provided by recent technological advances. 相似文献
