Background: The researchers involved in this study work at Exeter Health library and at the Complementary Medicine Unit, Peninsula School of Medicine and Dentistry (PCMD). Within this collaborative environment it is possible to access the electronic resources of three institutions. This includes access to amed and other databases using different interfaces. Objectives: The aim of this study was to investigate whether searching different interfaces to the amed allied health and complementary medicine database produced the same results when using identical search terms. Methods: The following Internet‐based amed interfaces were searched: DIALOG DataStar; EBSCOhost and OVID SP_UI01.00.02. Search results from all three databases were saved in an endnote database to facilitate analysis. A checklist was also compiled comparing interface features. Results: In our initial search, DIALOG returned 29 hits, OVID 14 and Ebsco 8. If we assume that DIALOG returned 100% of potential hits, OVID initially returned only 48% of hits and EBSCOhost only 28%. In our search, a researcher using the Ebsco interface to carry out a simple search on amed would miss over 70% of possible search hits. Subsequent EBSCOhost searches on different subjects failed to find between 21 and 86% of the hits retrieved using the same keywords via DIALOG DataStar. In two cases, the simple EBSCOhost search failed to find any of the results found via DIALOG DataStar. Conclusions: Depending on the interface, the number of hits retrieved from the same database with the same simple search can vary dramatically. Some simple searches fail to retrieve a substantial percentage of citations. This may result in an uninformed literature review, research funding application or treatment intervention. In addition to ensuring that keywords, spelling and medical subject headings (MeSH) accurately reflect the nature of the search, database users should include wildcards and truncation and adapt their search strategy substantially to retrieve the maximum number of appropriate citations possible. Librarians should be aware of these differences when making purchasing decisions, carrying out literature searches and planning user education. 相似文献

This article investigates how instructors can utilize the integration of early literacy skills and the arts to cultivate the
appreciation and celebration of cultures in early childhood classrooms. The theoretical framework is developed through three
personal accounts establishing a rationale for the importance of a viable home to school connection for young children. Finally,
the suggested activities support the transference of theory into classroom practice. 相似文献

Although the Portuguese educational system advocates the accommodation of all students in regular schools, it has not adopted a coherent discourse that would contribute to meeting effectively the needs of students with specific learning disabilities (SLD). As such, the successive reorganizations of special education have resulted in uninformed decisions that have caused the education of students with SLD in Portugal to be, in many instances, detrimental to their academic and social growth. We describe the reality of SLD in Portugal, considering four main topics: (1) the establishment of the SLD concept, (2) the birth of a Portuguese definition of SLD, (3) the context of educational policy, and (4) the provision for students with SLD. 相似文献

Abstract This article extends a previous review of the literature ( Maccini & Hughes, 1997 ) on mathematics interventions for secondary school students with learning disabilities (LD). A systematic review of the literature from 1995 to 2006 yielded 23 articles that met the criteria for inclusion. It was determined that a number of practices demonstrated significant gains for secondary school students with LD in math, including mnemonic strategy instruction, graduated instructional approach, cognitive strategy instruction involving planning, schema‐based instruction, and contextualized videodisc instruction. We also discuss the nature and focus of math interventions and implications for both research and practice based on the findings. 相似文献

Objective: This study evaluated the emotional and behavioral adjustment of parents and children within 3 months and 1 year after the discovery of child extrafamilial sexual abuse.Method: Ninety-two case parents (63 mothers, 29 fathers) and 56 children were compared to a nonclinical comparison group of 136 parents (74 mothers, 62 fathers) and 75 children. Parent adjustment was assessed using self-report measures while child functioning was assessed using a combination of child-, parent- and teacher-report measures.Results: Mothers, fathers and sexually abused children experienced clinically significant effects both initially and at 12 months post-disclosure. Children’s perceptions of self-blame and guilt for the abuse and the extent of traumatization predicted their self-reported symtomatology at 3 months and 1 year post-disclosure. Child age and gender also significantly contributed to the prediction of many of the child outcome measures. No abuse-related variable was related to any child self-report measure. Mothers’ satisfaction in the parenting role, perceived support and intrusive symptoms predicted their initial emotional functioning. Avoidant symptoms, child’s internalizing behavior and mothers’ initial emotional functioning were significant predictors of longer-term emotional functioning.Conclusions: Results emphasize the need to address children’s abuse-related attributions and underscore the need to expand our focus beyond the child victims to the traumatized families. 相似文献

We investigate two non-iterative estimation procedures for Rasch models, the pair-wise estimation procedure (PAIR) and the Eigenvector method (EVM), and identify theoretical issues with EVM for rating scale model (RSM) threshold estimation. We develop a new procedure to resolve these issues—the conditional pairwise adjacent thresholds procedure (CPAT)—and test the methods using a large number of simulated datasets to compare the estimates against known generating parameters. We find support for our hypotheses, in particular that EVM threshold estimates suffer from theoretical issues which lead to biased estimates and that CPAT represents a means of resolving these issues. These findings are both statistically significant (p < .001) and of a large effect size. We conclude that CPAT deserves serious consideration as a conditional, computationally efficient approach to Rasch parameter estimation for the RSM. CPAT has particular potential for use in contexts where computational load may be an issue, such as systems with multiple online algorithms and large test banks with sparse data designs. 相似文献

Intermediary actors have been proposed as key catalysts that speed up change towards more sustainable socio-technical systems. Research on this topic has gradually gained traction since 2009, but has been complicated by the inconsistency regarding what intermediaries are in the context of such transitions and which activities they focus on, or should focus on. We briefly elaborate on the conceptual foundations of the studies of intermediaries in transitions, and how intermediaries have been connected to different transition theories. This shows the divergence – and sometimes a lack – of conceptual foundations in this research. In terms of transitions theories, many studies connect to the multi-level perspective and strategic niche management, while intermediaries in technological innovation systems and transition management have been much less explored. We aim to bring more clarity to the topic of intermediaries in transitions by providing a definition of transition intermediaries and a typology of five intermediary types that is sensitive to the emergence, neutrality and goals of intermediary actors as well as their context and level of action. Some intermediaries are specifically set up to facilitate transitions, while others grow into the role during the process of socio-technical change. Based on the study, as an important consideration for future innovation governance, we argue that systemic and niche intermediaries are the most crucial forms of intermediary actors in transitions, but they need to be complemented by a full ecology of intermediaries, including regime-based transition intermediaries, process intermediaries and user intermediaries. 相似文献

In this article, we examine the discursive construction of knowledge about immigration in two geographic spaces whose “border” many students navigate: a school context meant to support English Language Learners and an out-of-school faith based organization serving immigrant communities. We draw on the concept of “border thinking” (Mignolo, 2000, p. 18) to understand how colonial histories continue to influence contemporary educational contexts. Through examples from students’, community members’, and educators’ interactions with available discourses of immigration, we elaborate on the implications of community knowledge for revising school practices to represent a fuller complexity of immigration experiences. 相似文献

By changing the level of competition and/or affecting the allocation of resources, institutions can play a very important role on innovation activity. In this paper we investigate the relative importance of institutional variation across European countries in explaining differences in their innovation intensity at the industry level. We employ a novel indicator of innovation therefore circumventing the limitations of more traditional indicators. Our results are broadly consistent with previous empirical literature. They show that stringent product and labor market regulation affects innovation intensity negatively, and that more developed credit markets foster innovation. However, the empirical findings also raise doubts with respect to the strengthening of intellectual property rights as a means to stimulate innovation, a result that is in accordance with recent propositions in the literature. 相似文献
