Do achievement goals mediate stereotype threat?: an investigation on females' soccer performance     

Chalabaev A  Sarrazinr P  Stone J  Cury F 《运动与训练心理学杂志》2008,30(2):143-158

This research investigated stereotype threat effects on women's performance in sports and examined the mediation of this effect by achievement goals. The influence of two stereotypes-relative to the poor athletic ability and the poor technical soccer ability of women-were studied. Fifty-one female soccer players were randomly assigned to one of three conditions, introducing the task as diagnostic of athletic ability, technical soccer ability, or sports psychology. Next, they filled out a questionnaire measuring achievement goals and performed a soccer dribbling task. Results showed that compared with the control condition, females' performance significantly decreased in the athletic ability condition and tended to decrease in the technical soccer ability condition. Moreover, participants endorsed a performance-avoidance (relative to performance-approach) goal when the stereotypes were activated. However, this goal endorsement was not related to performance. The implications of these results for understanding the role of stereotypes in gender inequalities in sports are discussed.  相似文献   

If you build it,will they come?: A case study of digital spaces and brand in the National Basketball Association     

Michael E. Pfahl  Andrew Kreutzer  Mike Maleski  Jeff Lillibridge  Jeff Ryznar 《Sport Management Review》2012,15(4):518-537

This case addresses the relationship between sport and digital spaces by introducing students to strategic marketing processes related to developing a team-managed fan website. The case was created in conjunction with three former members of the Cleveland Cavaliers who helped create www.cavfanatic.com, the official fan site of the team. Key areas addressed within the case study are brand development, brand communication, and brand extension. The case follows a new hire, Natalie, as she joins the new media team of www.cavfanatic.com. The sport marketers she works with review the development of the website and provide information on the strategic development process they went through. In the end, Natalie is charged with looking forward and developing further strategies to continue to engage the Cavaliers fans and to develop the CavFanatic brand.  相似文献   

The Role of Agricultural Consultants in New Zealand in Environmental Extension     

Neels Botha  Jeff Coutts  Hein Roth 《The Journal of Agricultural Education and Extension》2013,19(2):125-138

Abstract

The aim of this study was to understand the role that agricultural consultants in New Zealand were undertaking in the Research, Development and Extension (RD&E) system—and in particular in relation to environmental extension. New Zealand does not have a public extension service and hence there is a strong reliance on consultants and regional councils for environmental management information and advice. As they are independent of the formal RD&E system there is no guarantee that RD&E outcomes are reaching farmers, nor that effective environmental extension is occurring. The study used a combination of case studies, phone interviews with informed persons and a national web survey to explore the role of the consultant. The study found that agricultural consultants are playing an important role in working with farmers to improve agricultural production. There are, however, indications that gaps have developed over time between agricultural consultants and the agricultural research sector which limit the effectiveness of the RD&E system. Agricultural consultants are playing a minimal role in proactive environmental extension because insufficient market forces are driving this role. The paper suggests that a national database of agricultural consultants could improve the flow of tailored information between research and agricultural consultants and also suggests mechanisms where consultants could be better integrated into the RD&E system and provide feedback to research programs. Market failure in the area of environmental extension could be addressed by publicly funded incentive programs.  相似文献

Student-centredness: the link between transforming students and transforming ourselves     

Margaret A.L. Blackie  Jennifer M. Case  Jeff Jawitz 《Teaching in Higher Education》2013,18(6):637-646

It is widely accepted in the higher education literature that a student-centred approach is pedagogically superior to a teacher-centred approach. In this paper, we explore the notion of student-centredness as a threshold concept and the implications this might have for academic staff development. We argue that the term student-centred in the Rogerian sense implies a focus on the person of the student and is deeply resonant with Barnett's assertion that the emergent being of the student is as important as the development of skills and knowledge. To facilitate transformative learning in higher education an academic must know how to value the person of the student in the learning process. Academic staff development initiatives need to work with the person of the academic and take into account the level of personal development required for each academic to be able to facilitate this kind of learning.  相似文献

Validation of a videogrammetry technique for analysing American football helmet kinematics     

Ann Bailey  James Funk  David Lessley  Chris Sherwood  Jeff Crandall  William Neale 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(5):678-700

ABSTRACT

Professional American football games are recorded in digital video with multiple cameras, often at high resolution and high frame rates. The purpose of this study was to evaluate the accuracy of a videogrammetry technique to calculate translational and rotational helmet velocity before, during and after a helmet impact. In total, 10 football impacts were staged in a National Football League (NFL) stadium by propelling helmeted 50th percentile male crash test dummies into each other or the ground at speeds and orientations representative of concussive impacts for NFL players. The tests were recorded by experienced sports film crews to obtain video coverage and quality typically available for NFL games. A videogrammetry procedure was used to track the position and rotation of the helmet throughout the relevant time interval of the head impact. Compared with rigidly mounted retroreflective marker three dimensional (3-D) motion tracking that was concurrently collected in the experiments, videogrammetry accurately calculated changes in translational and rotational velocity of the helmet using high frame rate (two cameras at 240 Hz) video (7% and 15% error, respectively). Low frame rate (2 cameras at 60 Hz) video was adequate for calculating pre-impact translational velocity but not for calculating the translational or rotational velocity change of the helmet during impact.  相似文献   

The long tail: a usage analysis of pre-1993 print biomedical journal literature     

Susan Starr  Jeff Williams 《Journal of the Medical Library Association》2008,96(1):20-27

Objective: The research analyzes usage of a major biomedical library''s pre-1993 print journal collection.Methodology: In July 2003, in preparation for a renovation and expansion project, the Biomedical Library at the University of California, San Diego, moved all of its pre-1993 journal volumes off-site, with the exception of twenty-two heavily used titles. Patrons wishing to consult one of these stored volumes could request that it be delivered to the library for their use. In the spring of 2006, an analysis was made of these requests.Results: By July of 2006, 79,827 journal volumes published in 1992 or earlier had been requested from storage. The number of requests received declined with age of publication. The usage distribution exhibited a “long tail”: 50% of the 79,827 requests were for journal volumes published before 1986. The availability of electronic access dramatically reduced the chance that corresponding print journal volumes would be requested.Conclusions: The older biomedical print journal literature appears to be of continued value to the biomedical research community. When electronic access was provided to the older literature, demand for older print volumes declined dramatically.

Highlights

• Analysis of requests for stored biomedical journal volumes published prior to 1993 indicates that older biomedical journal literature receives substantial use: during this 3-year study, there were nearly 80,000 requests for journal volumes published in 1992 or earlier, with half the requests for volumes published from 1986–1992 and 40% of the request for volumes published from 1970–1985. These results indicate that retaining older print volumes, or providing easy access to the older literature through electronic journals or other means, will likely be required to meet user information needs.
• Use of older journal volumes varies by title and by user population, and a small number of journal titles were responsible for most of the use.
• Requests for older print biomedical journal titles dropped significantly when electronic access became available.

Implications

• Biomedical libraries should carefully consider implications of eliminating on-site access to older journal literature for users and budgets.
• Removing access to older journal literature may result in higher demand for interlibrary loan and document delivery services.
• Biomedical libraries can safely substitute reliable electronic access to older literature to meet ongoing needs for this information, thereby creating space for other purposes.

Construct Validity of Adults’ Retrospective Memory for Childhood TV Viewing: Self-Reported Early Exposure to Violent TV Programs Predicts Current Aggression     

Jeff Seger 《Communication methods and measures》2017,11(1):31-48

Construct validity was investigated of a measure of remote past television viewing in which adults reported their childhood viewing of specific television series. Good recall of past viewing was predicted due to two robust memory capabilities, specifically, high accuracy at estimating frequency of exposure to stimuli, and durable long-term memories for repeatedly-encountered material. Validity was tested by examining relationships between self-reported childhood TV viewing and current aggression. Results indicated that recalled childhood viewing of programs containing violent content was positively related to adult aggressive behavior directly, and aggressive cognitions indirectly, independently of adult exposure to violent TV programs, exposure to nonviolent TV programs, parental disciplinary style, and sex. A valid self-report measure of remote past TV viewing behavior can enable researchers to examine, in a relatively quick and inexpensive manner, long-term relationships between early viewing of any television content and any later psychological outcomes of interest.  相似文献   

Team-Based Ultrasound Objective Structured Practice Examination (OSPE) in the Anatomy Course     

Taylor M. Weiskittel  Nirusha Lachman  Anjali Bhagra  Kylie Andersen  Jeff St. Jeor  Wojciech Pawlina 《Anatomical sciences education》2021,14(3):377-384

The clinical use of ultrasound has dramatically increased, necessitating early ultrasound education and the development of new tools in ultrasound training and assessment. The goal of this study was to devise a novel low-resource examination that tested the anatomical knowledge and technical skill of early undergraduate medical students in a gross anatomy course. The team-based ultrasound objective structured practice examination (OSPE) was created as a method for assessing practical ultrasound competencies, anatomical knowledge, and non-technical skills such as teamwork and professionalism. The examination utilized a rotation of students through four team roles as they scanned different areas of the body. This station-based examination required four models and four instructors, and tested ultrasound skills in the heart, abdominal vessels, abdominal organs, and neck regions. A Likert scale survey assessed student attitudes toward the examination. Survey data from participants (n = 46) were examined along with OSPE examination grades (n = 52). Mean and standard deviations were calculated for examination items and survey responses. Student grades were high in both technical (96.5%). and professional (96.5%) competencies with structure identification scoring the lowest (93.8%). There were no statistical differences between performances in each of the body regions being scanned. The survey showed that students deemed the examination to be fair and effective. In addition, students agreed that the examination motivated them to practice ultrasound. The team-based OSPE was found to be an efficient and student-favored method for evaluating integrated ultrasound competencies, anatomical knowledge, team-work, and professional attributes.  相似文献
