This essay is a preliminary assessment of David Bearman as the leading archival thinker of the late twentieth century. Bearman has revolutionized thinking in archival circles around the world by offering a defence of traditional archival notions of provenance, evidence, recordness, and contextuality that equals the noblest statements of a Hilary Jenkinson, and by positing a relevant, dynamic, engaged future for archivists to transform the Information Age into a Record-Keeping Age. The essay is both a personal reflection and critical analysis. There are three main themes: an assessment of Bearman's ideas and their overall importance to general archival theory; a more specific exposition of the nature and importance of the University of Pittsburgh Project and of where Bearman sees that its results are leading archivists and their profession and institutions in future; and a critique of some of the implications, if not the conscious intentions, of his ideas and methods that seem to exclude the cultural, historical, and heritage dimensions and uses of archives, public or private. The overall aim of the essay is to push the archival discourse to the next stage by challenging and constructively critiquing as well as extolling the work of this archival pioneer. 相似文献

The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., 1999) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n = 584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index = 0.92, Tucker-Lewis index = 0.88, root mean square error of approximation = 0.05) but minimal support for the training items (robust comparative fit index = 0.86, Tucker-Lewis index = 0.81, root mean square error of approximation = 0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required. 相似文献

The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls. 相似文献

This study explored the relationship between metacognition and intelligence in a group of normal adolescents. The relationship has strong theoretical support in current conceptions of intelligence. For the purposes of this study metacognition was assessed across three different cognitive problem sets. Correlational analyses indicated a nonsignificant relationship between intelligence and metacognition. These results suggest that tests of metacognition and intelligence may tap unrelated aspects of cognition and that additional research will be required to understand the relationship between these two constructs. 相似文献

The Ward Chipman Library on the Saint John campus of the University of New Brunswick is home to a freestanding collection of over 32,000 science fiction and fantasy works, including reference material, primary works, magazines, and mass market/pulp items from most of the 20th century. Some scholars, including Dr. Farah Mendlesohn of Middlesex University, have described it as one of the best in the world. Active development of this collection ceased in 2000 however, and in recent years it has been primarily used as a popular reading collection, with little academic use. A decision to reduce the collection to one designed solely for academic research was met with great protest, and subsequently the collection was weeded and the remainder moved to storage to free up space for other library initiatives. The article describes the collection, the reasons for the proposed and actual reductions, the protests, and the valuable lessons learned from the experience, including the importance of collection development and management policies, the importance of involving the user community to ensure that everyone's needs are met, and the tensions that sometimes arise when intellectual and practical concerns collide. 相似文献

Although a number of studies document the fact that adult males interrupt females more often than females interrupt males, less is known about whether this behavior is also true of younger boys and girls. This study examined some aspects of dominant-submissive sex role behavior in preschool children and their teachers during conversation at the snack table. It asked whether there was any difference in the number of times girls and boys interrupted their teacher, and whether there was any difference in the number of times the teacher interrupted boys or girls. In succeeding observations, researchers investigated whether girls or boys were assigned the privilege of passing snack more frequently.In Investigation 1 nine boys and nine girls, 4 years of age, were observed talking with a variety of student teachers in a naturalistic snack setting, and checklists were kept of the number of teacher-child, child-teacher interruptions during conversation. In Investigation 2, tallies were kept of the number of times boys and girls assumed the dominant roles of distributing snacks and snack materials.Results indicted that during conversation, boys interrupted their teachers more frequently than the girls did (p > .03). Teachers interrupted girls more frequently than they interrupted boys (p > .02). No significant differences were found in the frequency of participation by boys or girls in passing snack. Results are discussed in relation to the teacher's role in teaching dominant-submissive sex role behaviors to children. 相似文献

Challenging discourses of aspiration: The role of expectations and attainment in access to higher education 下载免费PDF全文
Raising the proportion of young people from disadvantaged backgrounds progressing to higher education has been a key policy objective for successive governments in the UK since the late 1990s. Often this has been conceptualised as a problem with their ‘aspirations’, with the solution being seen as the provision of ‘aspiration‐raising’ activities to promote higher education to those thought to have the potential to progress. Recent large‐scale studies cast strong doubt on this hypothesis by demonstrating that aspirations are not generally low, that different social groups have similar levels of aspiration and that school attainment accounts for nearly all the differences in participation rates between social groups. This article draws on data from a national project exploring efforts to widen participation across two generations of practitioner‐managers in England, focusing on their conceptualisations of the field and their constructions of ‘successful’ activities. It uses the lens of ‘possible selves’ (Markus & Nurius, 1986 ) to argue that too much policy emphasis has been placed on the aspirations of young people, rather than either their academic attainment or their expectations, which are shaped by the normative expectations of the adults surrounding them. In addition, the more expansive concepts of widening participation that were present a decade ago have become less common, with a shift towards activities with a clear role in institutional recruitment rather than social transformation. The article concludes with alternative suggestions for policy and practice. 相似文献
