The aim of this study was to provide contemporary information on injury rates in an elite and sub-elite netball population and to explore the relationship between lower body stiffness and lower body injuries. One elite and two sub-elite teams of female netballers (n = 29) performed the vertical hop test to assess active lower body stiffness (K_vert) and myometry to assess quasi-static stiffness. Lower body injuries were monitored via self-reporting and liaison with physiotherapists. Twelve lower body non-contact injuries were sustained by 10 players, equating to 11.29 lower body injuries per 1,000 exposure hours. The most commonly injured sites were the calf (33%) and ankle (25%). No significant differences between K_vert of injured and non-injured players were reported, however, injured elite players recorded significantly higher season mean quasi-static stiffness in the soleus (p = 0.037) and Achilles (p = 0.004) than non-injured elite players. Elite and sub-elite netball players recorded a higher injury incidence than previous reports of injuries in recreational netballers. Within the constraints of the study, relatively high stiffness of the soleus and Achilles appears to be related to lower body non-contact injury incidence in female netballers, particularly at the elite level. These results provide a basis for development of injury prevention strategies.  相似文献   

The Impact of Management Education     

Rob Hartz  Richard P. Niemiec  Herbert J. Walberg 《Performance Improvement Quarterly》1993,6(1):67-76

This article summarizes research findings of a study that examined the effects of a sales management training program conducted at Digital Equipment Corporation. The authors used a typology of training outcomes developed by Kirkpatrick (1959a, 1959b, 1960a, and 1960b) to assess students' satisfaction, learning, and field implementation of skills taught in the class. In addition, they estimated the costs of the program and the actual increase in sales that can be attributed to the implementation of the skills in the workplace. The results indicate that properly conceived and carefully implemented programs have a positive net effect on the corporation's financial position.  相似文献   

Spectral city: San Francisco as Pacific Rim city and counter‐cultural contado     

Rob Wilson 《Inter-Asia Cultural Studies》2013,14(4):583-597

Abstract

San Francisco, since its global takeoff in the Gold Rush Days and long‐standing trafficking in Bohemian, socialist, queer, and left‐leaning energies in and beyond the Beat era of the 1960s, has a complicated global/local history of trying to disentangle its city‐space and urban imaginary from the Greco‐Roman will‐to‐supremacy that would turn California into a frontier settlement of Asian/Pacific domination and US‐framed empire. Forces of social becoming like the Beats and post‐Beat hippies as well as more experimental authors like Jack Spicer, Maxine Hong Kingston, Frank Chin, and Bob Kaufman helped to forge a different literary‐social vision of San Francisco and the Pacific Rim city as a porous community of transnational innovation and outer‐national becoming. This paper will invoke some literary and film texts from Howl and Tripmaster Monkey to Vertigo to Margaret Cho stand‐up performances as well as some geopolitical studies, such as Gray Brechin’s Imperial San Francisco and City Light Press’s Reclaiming San Francisco to substantiate this double vision of San Francisco as global/local US site of (a) imperial ratification and (b) counter‐orientalist deformation.  相似文献

Sex differences in the acceptability and short-term outcomes of a web-based personalized feedback alcohol intervention for high school seniors     

Diana M. Doumas  Susan Esp  Rob Turrisi  Laura Bond  Sherise Porchia  Brian Flay 《Psychology in the schools》2020,57(11):1724-1740

Despite the escalation of alcohol use through high school, the majority of research on school-based alcohol interventions has been conducted with junior high students or first and second-year high school students. Preliminary research indicates a brief, web-based personalized feedback intervention developed for college students (eCHECKUP TO GO) may be a promising program for high school seniors. Although these studies demonstrate positive intervention effects, there is some evidence for greater program efficacy for females in this age group. The current study investigates sex differences in program acceptability of the eCHECKUP TO GO and its relationship to short-term alcohol outcomes among high school seniors (N = 135). Overall, the majority of students reported they found the program to be acceptable (i.e., user-friendly and useful). However, contrary to our hypothesis, results indicated that male students reported significantly higher perceptions of program acceptability than females. Although we did not find sex differences in alcohol outcomes, program user-friendliness was related to reductions in alcohol use for males. The results of this study add to the literature supporting the eCHECKUP TO GO for high school seniors and highlight the importance of program user-friendliness for males. Implications for implementing the program as a school-based intervention are discussed.  相似文献

Gender‐Based Differential Prediction by Curriculum Samples for College Admissions     

A. Susan M. Niessen  Rob R. Meijer  Jorge N. Tendeiro 《Educational Measurement》2019,38(3):33-45

A longstanding concern about admissions to higher education is the underprediction of female academic performance by admission test scores. One explanation for these findings is selection system bias, that is, not all relevant KSAOs that are related to academic performance and gender are included in the prediction model. One solution to this problem is to include these omitted KSAOs in the prediction model, many of these KSAOs are 'noncognitive' and “hard‐to‐measure” skills in a high‐stakes context. An alternative approach to capture relevant KSAOs is using representative performance samples. We examined differential prediction of first year‐ and third year academic performance by gender based on a curriculum‐sampling test that was designed as a small‐scale simulation of later college performance. In addition, we examined differential prediction using both frequentist and Bayesian analyses. Our results showed no differential prediction or small female underprediction when using the curriculum‐sampling tests to predict first year GPA, and no differential prediction for predicting third year GPA. In addition, our results suggest that more comprehensive curriculum samples may show less differential prediction. We conclude that curriculum sampling may offer a practically feasible method that yields minimal differential prediction by gender in high‐stakes operational selection settings.  相似文献   

Assessing Anonymous Communication on the Internet: Policy Deliberations     

Rob Kling  Ya-Ching Lee  Al Teich  Mark S. Frankel 《The Information Society》1999,15(2):79-90

Anonymous communication on the Internet offers new opportunities but has ill-understood risks. This article helps to ground the policy debates by examining some fundamental aspects of anonymous social behavior and current controversies over anonymous communications. It is a companion to the article in this issue, "Anonymous Communication Policies for the Internet: Results and Recommendations of the AAAS Conference." It examines the social character of anonymous communication and the ways that anonymous communication has played important roles for professionals such as journalists and the police. It also explains some of the new technological supports for anonymous communication on the Internet. The openness, decentralization, and transnational character of the Internet challenge the efficacy of traditional control mechanisms and have raised issues related to accountability, law enforcement, security and privacy, governmental empowerment, and e-commerce. Yet, to ban or restrict all anonymous communication online because of the harms it could bring would deny its benefits to those people who may legitimately gain from it. This article helps to understand how to balance these positions.  相似文献   

Anonymous Communication Policies for the Internet: Results and Recommendations of the AAAS Conference     

Al Teich  Mark S. Frankel  Rob Kling  Ya-Ching Lee 《The Information Society》1999,15(2):71-77

The Internet offers new opportunities for anonymous and pseudonymous communications. Users can, for example, engage in political advocacy, receive counseling, and perform commercial transactions without disclosing their identities. The cloak of anonymity can also facilitate socially unacceptable or criminal activities because of the difficulty in holding anonymous users accountable. This article reports the results of a conference on anonymous communication organized by the American Association for the Advancement of Science. Among the findings were that online anonymous communication is morally neutral; that it should be considered a strong human and constitutional right; that online communities should be allowed to set their own policies on the use of anonymous communication; and that individuals should be informed about the extent to which their identity is disclosed online. The article discusses how anonymous communications can be shaped by the law, education, and public awareness, and highlights the importance of involving all affected interests in policy development.  相似文献
