The aim of this study was to determine the level of awareness of methodological search filters among health and academic librarians in the UK and Ireland, their use of filters and views on the perceived benefits, limitations and ways to increase usage of search filters. A random proportional sample of health and academic librarians were surveyed by telephone and fax. Overall, 88% (196/224) completed the telephone survey to establish awareness and use of filters. Eighty-four per cent (51/61) completed a fax survey focusing in more depth on usability issues surrounding filters. Results indicate a high level of awareness of methodological filters, but low level of usage. Furthermore, a high level of awareness did not necessarily correlate with a high level of knowledge or understanding. Examination of responses revealed limitations and recommendations beyond those reported in the literature and highlights the relationship between understanding and effective use of filters. Improved dissemination and publication of filters is required to better inform librarians on the concept of filters and how to use them effectively.  相似文献

We examined the intersection of students' understanding and acceptance of evolution and their epistemological beliefs and cognitive dispositions. Based on previous research, we hypothesized there would be a relation between understanding and acceptance. We also hypothesized that students who viewed knowledge as changing and who have a disposition toward open‐minded thinking would be more likely to accept the scientific explanation of human evolution, and that beliefs and dispositions would not be related to acceptance of a topic that is generally perceived as noncontroversial. Ninety‐three undergraduate students enrolled in a nonmajors biology class completed measures of their (a) content knowledge of evolution and photosynthesis and respiration; (b) acceptance of theories of animal evolution, human evolution, and photosynthesis; and (c) epistemological beliefs and cognitive dispositions. Although our findings did reveal a significant relation between knowledge and reported acceptance for photosynthesis, there was no relation between knowledge and acceptance of animal or human evolution. Epistemological beliefs were related to acceptance, but only to the acceptance of human evolution. There was no relation between students' epistemological beliefs and their general acceptance of animal evolution or photosynthesis. Three subscales, Ambiguous Information, Actively Open‐Minded Thinking, and Belief Identification, were significantly correlated with understanding evolutionary theory. We argue these findings underscore the importance of intentional level constructs, such as epistemological beliefs and cognitive dispositions, in the learning of potentially controversial topics. © 2003 Wiley Periodicals, Inc.

OBJECTIVE: The aim of this study was to examine the trajectory of cases through four systems: child protection, law enforcement, the dependency courts, and the criminal courts. METHOD: This study focused on a county selected from a 41-county telephone survey conducted for the National Incidence Study of Child Abuse and Neglect (NIS-3). For this analysis prospective samples were drawn from law enforcement (n=225) and the county child protection (CPS) agency (n=225) and followed through in-depth case tracking across all agencies and through both the dependency and criminal court systems. RESULTS: The percentage of CPS cases opened in dependency court was similar to prior studies (29%), but the acceptance and prosecution rates were much higher--92% of the cases referred from CPS, including many cases of physical abuse. Compared to referrals from CPS to law enforcement (93%), few cases were referred from law enforcement to CPS (17%). Anecdotally, case referral patterns appeared to be influenced by communication patterns and mutual positive regard, regardless of the collaborative protocols in place. One of the most instructive findings was the degree of difficulty in tracking cases across organizations and the types of obstacles that impeded success. Disorganization was not an issue, rather internal structures set up to facilitate intra-organizational processing were the same structures that actually impeded cross-organizational case finding. CONCLUSIONS: It is not sufficient to rely on the existence of multi-disciplinary teams or Child Advocacy Centers to ensure collaboration. More attention to daily tasks and activities as well as the nature and quality of communication is warranted. On the technical side, use of common case identifiers on cases that are cross-referred is strongly recommended. Future studies should broaden the scope of inquiry to include the consequences of all case trajectories, rather than solely focusing on the justice system.  相似文献

The characteristics of 273 male science teachers were compared with 72 female science teachers randomly selected from a fourteen-state region in the USA. A multivariate analysis of variance found differences between the two groups significant at the p ? 0.0005 level. Female teachers were higher on measures of interest in science and receptivity to change. Males scored higher on science knowledge indicators and on their perceptions of the teaching support they received. No differences were noted on measures of professional development or their perceptions of teaching effectiveness, curriculum, workload, or facilities. The implications of the findings are discussed in terms of science career selection by women.  相似文献

The academic and social integration of college students has been the focus of much recent research. The Tinto model of college student withdrawal focused on the constructs as explanation for commitment to goals and persistence. Research results suggested that perhaps reciprocal relationships existed between academic and social integration. Significant influences from academic integration to social integration and vice-versa indicated differing reciprocal effects for males and females.  相似文献

The purpose of the study was to examine the efficacy of a 4-week dialogic reading intervention with rural Bangladeshi preschoolers with the intention of increasing their expressive vocabulary. Eighty preschoolers randomly selected from five preschools participated in the 4-week program. Their expressive vocabulary, measured in terms of definitions, was tested on 170 challenging words before and after the program and compared with that of control children who participated in the regular language program. Both groups were read in Bangla eight children's storybooks with illustrations, but the dialogic reading teacher was given a set of “wh” and definitional questions to enhance children's verbal participation. The mean vocabulary scores of dialogic program children increased from 26% to 54% whereas the control children remained at the same level. Results are discussed in terms of the successful application of dialogic reading to low-resource preschools.  相似文献

Friendships and play provide children with opportunities for mutual engagement, which both require and facilitate children's language use. Modality is a semantic system in the language associated with children's learning. One way in which modality is realised is through linguistic expressions which allow speakers to moderate the degree of certainty about the truth of propositions (expressions of possibility) and the degree of necessity with respect to proposals (expressions of obligation). No research has explored the relationship between friendship and children's use of modality. This paper reports on the use of both types of modal expression during play between five- and six-year-old children in two friendship contexts. Results showed that possibility expressions occurred at similar rates in both contexts while obligation expressions occurred significantly more often in play in high-level friendships than in low-level friendships. Findings suggest that in high-level friendships modality was used cohesively to create and extend pretend play, whereas in low-level friendships it was used to regulate behaviour. Because modal expressions are important resources for managing interpersonal relationships, for talking about ideas and situations beyond the here and now and for writing for a non-present audience, our findings provide valuable insights for educators of young children.  相似文献

Western cultural practices contribute to our understanding of the purpose of higher education and how we are to conduct ourselves in educational contexts. In this article, entitled ‘Seekers after truth?’, I analyse recent works of popular fiction which draw on and contribute to the idea that postgraduate research is a process of locating and amassing clues leading to the revelation or discovery of a truth. These novels re-inscribe the metaphor of the postgraduate researcher as detective or ‘seeker after truth’. This article considers the contradictory and productive meanings that arise from the trope of the researcher-detective. In addition, I argue that, although there are challenges in bringing the work of one field to bear on another, analyses of discourses which are not produced within higher educational contexts can nonetheless promote reflection on educational concepts. In this case, fiction enables us to consider ideas about what it is to do postgraduate research and to be a postgraduate researcher.  相似文献
