The adaptation of experimental cognitive tasks into measures that can be used to quantify neurocognitive outcomes in translational studies and clinical trials has become a key component of the strategy to address psychiatric and neurological disorders. Unfortunately, while most experimental cognitive tests have strong theoretical bases, they can have poor psychometric properties, leaving them vulnerable to measurement challenges that undermine their use in applied settings. Item response theory–based computerized adaptive testing has been proposed as a solution but has been limited in experimental and translational research due to its large sample requirements. We present a generalized latent variable model that, when combined with strong parametric assumptions based on mathematical cognitive models, permits the use of adaptive testing without large samples or the need to precalibrate item parameters. The approach is demonstrated using data from a common measure of working memory—the N-back task—collected across a diverse sample of participants. After evaluating dimensionality and model fit, we conducted a simulation study to compare adaptive versus nonadaptive testing. Computerized adaptive testing either made the task 36% more efficient or score estimates 23% more precise, when compared to nonadaptive testing. This proof-of-concept study demonstrates that latent variable modeling and adaptive testing can be used in experimental cognitive testing even with relatively small samples. Adaptive testing has the potential to improve the impact and replicability of findings from translational studies and clinical trials that use experimental cognitive tasks as outcome measures. 相似文献

Although victim-offender conferences (VOCs) ostensibly enable victims to pursue justice goals not achieved through conventional trials, not all victims wish to participate in them. The purpose of this study was to examine how victims’ presumptions regarding the effectiveness of VOCs and trials in accomplishing justice goals influence their willingness to participate in a VOC and their preference for a case to be managed solely by the courts. Study results indicated that participants believed VOCs and trials to be effective at accomplishing different goals and that such influenced how they wanted cases to be managed. This influence was moderated by desires for particular justice goals. These findings have implications for restorative justice researchers and practitioners interested in victims’ motivations to participate in a VOC. 相似文献

Higher education worldwide is beset by rigid budgetary constraints. Increases in governmental and student support have been insufficient to offset the severe inflationary spiral of recent years, and many institutions have been confronted by yearly gaps between estimated revenues and projected expenditures. Following 6 years of across-the-board internal budget reallocations amounting to $11.1 million, Penn State initiated a rolling 5-year planning and budget process in 1977. The new process, resulting in an additional $16.6 million in internal reductions and reallocations through 1982–83, was designed to provide for more selective budgetary decisions based on careful analysis of university priorities. As the process has evolved, it has reoriented budget decisions toward university planning issues and qualitative concerns. 相似文献

Through an IBM partnership, Acadia University has the benefit of an infrastructure that places a laptop computer in the hands of some 4000 faculty and students on campus. Coupled with anytime–anyplace campus access to the computer network, the setting offers unique opportunities to study the pedagogical impacts of the use of computers in classroom instruction.University business administration courses have routinely employed case study approaches in the delivery of some course content. The research described follows the use of an elaborate case study communications networking system being used in a business course on competitive intelligence. Though the technology collage allows for certain opportunities to promote quality instruction, not all aspects of technology use were found to be productive. This paper provides an analysis of the appropriateness of technology usage in the context of a single business education course. 相似文献

Japanese education has been a focus of comparative studies for the past 20 years. Many scholars have attributed the economic
success of this industrialized society to a highly literate and well-educated population. Recent studies, however, have tended
to be more critical of, in particular, Japanese higher education (HE). Indeed, most universities in Japan are acutely aware
of the need for change and a considerable effort at institutional reform is sweeping the nation. Unfortunately most of the
constructive criticism of Japanese HE has not yet been published in English. One of the most vocal of the reformists, Professor
Ikuo Amano, has published widely on various aspects of HE in Japan. The following paper is a translation of a chapter in his
book Challenges to Japanese Universities. This translation is prefaced by both a synopsis of this book as well as a brief
introduction to Amano and his work. 相似文献

Parent academic involvement as related to school behavior, achievement, and aspirations: demographic variations across adolescence 总被引:2,自引:0,他引:2

A longitudinal model of parent academic involvement, behavioral problems, achievement, and aspirations was examined for 463 adolescents, followed from 7th (approximately 12 years old) through 11th (approximately 16 years old) grades. Parent academic involvement in 7th grade was negatively related to 8th-grade behavioral problems and positively related to 11th-grade aspirations. There were variations across parental education levels and ethnicity: Among the higher parental education group, parent academic involvement was related to fewer behavioral problems, which were related to achievement and then aspirations. For the lower parental education group, parent academic involvement was related to aspirations but not to behavior or achievement. Parent academic involvement was positively related to achievement for African Americans but not for European Americans. Parent academic involvement may be interpreted differently and serve different purposes across sociodemographic backgrounds. 相似文献

In spite of the name, simple linear regression presents a number of conceptual difficulties, particularly for introductory students. This article describes a simulation tool that provides a hands‐on method for illuminating the relationship between parameters and sample statistics. 相似文献
