Many sports associated with anterior cruciate ligament (ACL) injury require athletes attend to a ball during participation. We investigated effects of attending to a ball on lower extremity mechanics during a side-cut maneuver and if these effects are consistent for males and females. Sagittal and frontal plane hip and knee kinematics and joint moments were measured during side-cut maneuvers in 19 male and 19 female National Collegiate Athletic Association division III basketball players. Participants also experienced two side-cut conditions that required attention to a ball. Our results did not indicate that the effect of attention varies with gender. However, during side-cut conditions while attending to a ball, internal knee adductor moment was 20% greater (p = 0.03) and peak knee flexion angle was 4 degrees larger (p < 0.01). Females demonstrated 5 degrees less hip flexion (p = 0.046), 12 degrees less knee flexion (p < 0.01), and 4 degrees more knee abduction (p = 0.026) at initial contact during all side-cut conditions than males. Attention to a ball may affect lower extremity mechanics relevant to ACL injury. The validity of laboratory studies of lower extremity mechanics for sports that include attention to a ball may be increased if participants are required to attend to a ball during the task. 相似文献

Advances in technology are stimulating the development of complex, computerized assessments. The prevailing rationales for developing computer-based assessments are improved measurement and increased efficiency. In the midst of this measurement revolution, test developers and evaluators must revisit the notion of validity. In this article, we discuss the potential positive and negative effects computer-based testing could have on validity, review the literature regarding validation perspectives in computer-based testing, and provide suggestions regarding how to evaluate the contributions of computer-based testing to more valid measurement practices. We conclude that computer-based testing shows great promise for enhancing validity, but at this juncture, it remains equivocal whether technological innovations in assessment have led to more valid measurement. 相似文献

Sex offending is a considerable public health and criminal justice system concern. While the research is fairly mixed at best with most pointing toward a general lack of an appreciable deterrent benefit for these polices, no prior evaluation has made a rigorous attempt to determine and define the vast array of implementation costs and public safety benefits of these policies, specifically the Sex Offender and Registration and Notification Act (SORNA). As such, our proposed research strategy involves the development and application of an innovative Cost-Benefit Analysis (CBA) tool. The results from this innovative and dynamic CBA tool with hypothetical data suggests that the 10-year financial benefit for SORNA ranges from $1.01 to $3.91 for every dollar spent when considering the reduction in sex crime specifically, and any crime more generally. This tool holds promise as a mechanism for generating jurisdiction/site-specific cost-benefit analyses. Policy implications are also discussed. 相似文献
