Persistent fear of crime can have serious consequences for one’s social behavior. Previous research has shown that people who fear crime are more likely to engage in self-protective behavior. Although a substantial amount of research has examined the relationship between television exposure and fear of crime, research on the association between television exposure and self-protective behavior is scarce. Based on cultivation theory and the mediated fear model, the current study aimed to examine whether news and crime drama television viewing are indirectly related to self-protective behavior via fear of crime. Structural equation modeling of data from 392 undergraduate students showed that news viewing and crime drama viewing is indirectly associated with self-protective behavior. The current study provided evidence for the importance of accounting for gender when investigating the complex issue of media effects on fear of crime and self-protective behavior.  相似文献

The purpose of the study was to examine the psychometric quality of the National Board for Professional Teaching Standards (NBPTS) Early Childhood/Generalist assessment system. Rating data from the 1997–1998 assessment were analyzed using the FACETS (Linacre, 1998) computer program. The assessment system's 10 exercises work together to define a unidimensional accomplished teaching variable. There is little evidence of multidimensionality in the data, and none of the exercises appear to function in a redundant manner. The exercise set succeeds in defining several statistically distinct levels of accomplished teaching among the candidates. Overall, most candidate rating profiles show consistent performance across the exercises. While assessors differed somewhat in severity, most used the 12-point rating scale consistently. Although the range in assessor variability tends to be moderate, assessor severity does influence the number of candidates that can bank individual exercises. (If a candidate's total scaled score does not meet or exceed the NBPTS performance standard of 275, the candidate can bank scores on exercises in which the candidate received a final score of 2.75 or greater. If the candidate reapplies for certification in the next three years, the candidate does not have to retake banked exercises.)  相似文献

This column examines advances in public services internal and external to libraries. The focus is on how public services, such as instruction and education, programming, research consulting, and circulation evolve and impact users. The strength of the column is its broad, international focus and contributors are encouraged to explore issues and recent advances in public services relevant to their geographical region, as well as the larger, global audience. Interested authors are invited to submit proposals and articles to the column editor at   相似文献

This article is based on research with a group of one‐year Postgraduate Certificate in Education secondary trainee teachers during their initial teacher education and training in England. It considers tensions between trainees’ prior experiences and conceptions of teaching and their training programme. In doing so, it seeks to examine how a trainee’s dispositions as revealed through practice in various contexts are reflective of Bourdieu’s ‘habitus’. Associated with this, the paper also examines how particular forms of pre‐existing cultural capital and manifestations of biographical identity also pre‐dispose trainees to form affinities and disaffinities within particular fields. Lacanian concepts of the symbolic, imaginary and real are used to help explain how trainee teachers articulate resonance and dissonance during their field experiences, particularly in relation to ontological concerns of securing a professional stable sense of self.  相似文献

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper elementary and middle school students who are ELs and (b) how the magnitude of the effect varies based on student, instructional, and study characteristics. The analysis included a total of 11 studies with 46 individual effect sizes and yielded a mean effect size of g?=?0.35 across all (i.e., standardized and unstandardized) reading measures, g?=?0.01 across standardized reading measures, and g?=?0.43 across unstandardized reading measures. For all reading, unstandardized reading, all vocabulary, and unstandardized vocabulary measures, results suggest that higher quality studies tended to have smaller effects, and these effects were even more evident for unstandardized measures (i.e., one unit increase in study quality was associated with decreased effects: g?=?0.21, g?=?0.30, g?=?0.24, g?=?0.30, respectively). For all comprehension measures, effects were larger for instruction that included both vocabulary and comprehension (g?=?0.39) than for instruction that focused on vocabulary alone (g?=?0.08). Results suggest the benefit of developing and refining high-impact approaches to reading instruction for ELs that can be delivered across content areas and grades.  相似文献

A significant historical role in the development of competence-based vocational qualifications in England and Wales is customarily ascribed to the 1985 to 1986 Review of Vocational Qualifications (RVQ), the body which invented the National Vocational Qualification (NVQ). This paper analyses the RVQ's internal debates. The paper demonstrates that the RVQ proposed only the general principles of a structure and an administration for a reformed vocational qualifications system. The RVQ did not address in detail either the definition of occupational competence or the curriculum and assessment models to be embodied in the NVQ. In the light of this analysis, the paper re-evaluates the role of the RVQ in the development of competence-based vocational qualifications, and suggests some potentially fruitful areas for future research.  相似文献
