College and university leaders have paid an enormous level of attention to one domain of alumni involvement: charitable giving.
In light of the decline of state support for higher education and the shrinking ability of families to pay for college, such
emphasis is understandable. However, this emphasis has blinded scholars and practitioners to understanding the important non-monetary
support roles played by college alumni. Drawing on data from a research extensive university, this study employs a sequential
mixed method design (focus groups and confirmatory factor analysis) to demonstrate that non-monetary support behaviors are
best understood through the distinct, but interrelated domains of political advocacy and volunteerism. Political advocacy
behaviors include contacting legislators, the governor’s office, local politicians and serving on a political action team,
while volunteer behaviors include mentoring new alumni, recruiting students, and participating in special events. The study
breaks ground for future research on alumni support for higher education, including strategies to recruit alumni volunteers
and advocates. 相似文献

The aim of this study was to determine the precision and accuracy of the vertical and anterior–posterior force components of the portable PASCO PS-2142 force plate. Impulse, peak force, and time to peak force were assessed and compared to a gold standard force plate in three different tasks: vertical jump, forward jump, and sprint start. Two healthy male participants performed ten trials for each task, resulting in 60 trials. Data analyses revealed good precision and accuracy for the vertical component of the portable force plate, with relative bias and root mean square (RMS) error values nearly the same in all tasks for the impulse, time to peak force, and peak force parameters. Precision and accuracy of the anterior–posterior component were lower for the impulse and time to peak force, with relative bias and RMS error values nearly the same between tasks. Despite the lower precision and accuracy of the anterior–posterior component of the portable force plate, these errors were systematic, reflecting a good repeatability of the measure. In addition, all variables presented good agreement between the portable and gold standard platforms. Our results provide a good perspective for using the aforementioned portable force plate in sports and clinical biomechanics. 相似文献

This paper overviews the diverse information technologies that are used to provide athletes with relevant feedback. Examples taken from various sports are used to illustrate selected applications of technology-based feedback. Several feedback systems are discussed, including vision, audition and proprioception. Each technology described here is based on the assumption that feedback would eventually enhance skill acquisition and sport performance and, as such, its usefulness to athletes and coaches in training is critically evaluated. 相似文献

Computer-based educational assessments often include items that involve drag-and-drop responses. There are different ways that drag-and-drop items can be laid out and different choices that test developers can make when designing these items. Currently, these decisions are based on experts’ professional judgments and design constraints, rather than empirical research, which might threaten the validity of interpretations of test outcomes. To this end, we investigated the effect of drag-and-drop item features on test-taker performance and response strategies with a cognition-centered approach. Four hundred and seventy-six adult participants solved content-equivalent drag-and-drop mathematics items under five design variants. Results showed that: (a) test takers’ performance and response strategies were affected by the experimental manipulations, and (b) test takers mostly used cognitively efficient response strategies regardless of the manipulated item features. Implications of the findings are provided to support test developers’ design decisions. 相似文献

Automatic item generation (AIG)—a means of leveraging technology to create large quantities of items—requires a minimum number of items to offset the sizable upfront investment (i.e., model development and technology deployment) in order to achieve cost savings. In this cost–benefit analysis, we estimated the cost of each step of AIG and manual item writing and applied cost—benefit formulas to calculate the number of items that would have to be produced before the upfront costs of AIG outweigh manual item writing costs in the context of K‐12 mathematics items. Results indicated that AIG is more cost‐effective than manual item writing when developing, at a minimum, 173 to 247 items within one fine‐grained content area (e.g., fourth‐ through seventh‐grade area of figures). The article concludes with a discussion of implications for test developers and the nonmonetary tradeoffs involved in AIG. 相似文献
