A linear causal model is postulated and path analysis procedures are used to examine the direct, indirect, and total influence of 39 variables (grouped into eight general measures) on the salaries of 24.461 faculty members associated with virtually every discipline and type of postsecondary institution in the academic community. The results show wide variation in the relative influence of characteristics of postsecondary institutions and the personal and professional characteristics of faculty members on faculty salaries. The implications of these findings are discussed and specific guidelines are provided to assist those interested in examining the external and internal consistency of the faculty salary structures of their respective institutions.  相似文献

In four Pavlovian conditioned lick-suppression experiments, rats had two conditioned stimuli (CSs X and A) independently paired with footshock, followed by pairings of a compound of A and X with the footshock. On subsequent tests with CS X, less conditioned suppression was observed than in control subjects that lacked the compound AX→footshock trials. Thisoverexpectation effect was reversed through posttraining extinction of CS A, a result consistent with both performance- and acquisition-focused models of retrospective revaluation. However, only performance-focused models could account for how posttraining increases or decreases in the A-footshock temporal interval attenuate the overexpectation effect.  相似文献

This study evaluated the classification accuracy of a second grade oral reading fluency curriculum‐based measure (R‐CBM) in predicting third grade state test performance. It also compared the long‐term classification accuracy of local and publisher‐recommended R‐CBM cut scores. Participants were 266 students who were divided into a calibration sample (n = 170) and two cross‐validation samples (n = 46; n = 50), respectively. Using calibration sample data, local fall, winter, and spring R‐CBM cut scores for predicting students’ state test performance were developed using three methods: discriminant analysis (DA), logistic regression (LR), and receiver operating characteristic curve analysis (ROC). The classification accuracy of local and publisher‐recommended cut scores was evaluated across subsamples. Only DA and ROC produced cut scores that maintained adequate sensitivity (≥.70) across cohorts; however, LR and publisher‐recommended scores had higher levels of specificity and overall correct classification. Implications for developing local cut scores are discussed.  相似文献

Conclusion The Strategic Impact Model is distinctive in its portrayal of the integration of instructional and non-instructional interventions and its suggestion that all performance interventions undergo an analysis-design-development-production cycle, just as instruction does. It also differs from other similar models in its use of evaluative activities at each stage to assure alignment with strategic needs as well as quality control, and its suggestions for improving the chances of successful implementation by carrying out change management activities at each phase of the development process. He has special interests in distance education, historical and philosophical foundations of instructional technology and instructional development processes. He has special interests in planning and evaluating performance improvement initiatives, including training. An erratum to this article is available at .  相似文献

ABSTRACT

This national survey of PhD faculty assessed the research preparation of entering doctoral social work students on a wide range of research knowledge and related skills. The prior literature shows that PhD programs repeat much BSW and MSW research course content. This study shows that the trend continues and has perhaps widened. PhD research faculty report that the typical entering PhD student displayed solid conceptual, ethics, and writing skills but lesser preparation for conducting quantitative and qualitative research, including methods related to understanding evidence-based practice. The research expectations of responding PhD faculty were low, reflecting limited retention and little production of research among typical entering doctoral students. These findings raise the issue of how effectively the social work profession prepares students for research and for future PhD education.  相似文献

Following the trend of consequential accountability in US public education, New York City introduced a teacher evaluation program during the 2013–2014 school year that linked teachers’ individual performance ratings with their students’ exam scores. As this program systemically alters the nature of teacher–student relationships by transforming students into the means to an end (teachers’ professional viability), this study investigated the implementation of this accountability program from the point of view of the teachers – those who were the subject of this new policy. This study of 15 teachers’ narratives from 3 distinct schools illuminates a social-organizational process that I refer to as mediated institutional assault – a perceived attack on the teachers’ sense of personhood and moral agency perpetrated by mediating figures whose actions were facilitated by bureaucratic policies and institutionally coordinated tools of control. Thus, this study reveals that the consequence of this new mode of accountability is not merely the threat of losing one’s job, but also an insidious form of psychological assault, which in its masked delivery violates teachers’ sense of relational morality and challenges deeply engrained beliefs about their role as educators.  相似文献

Male albino rats were run in a discrete-trial two-bar operant analog of the double alley. Completion of a FR 4 response chain on the first bar was rewarded 50% of the time for the 12 experimental Ss, but was never rewarded for the 12 control Ss. Both groups received consistent reward at the end of a FR 4 chain on the second bar. Eighty-four trials were given at a rate of four trials per day. A significantly faster rate of responding on the second bar was found following nonrewarded first-bar ratios than following rewarded first-bar ratios. This frustration effect was not attributable to response depression, since the nonrewarded performance of the experimental group exceeded that of the control group.  相似文献
