Limb dominance theory suggests that females tend to be more one-leg dominant and exhibit greater kinematic and kinetic leg asymmetries than their male counterparts, contributing to the increased risk of anterior cruciate ligament injury among female athletes. Thus, the purpose of this study was to examine the influences of sex and limb dominance on lower extremity joint mechanics during unilateral land-and-cut manoeuvres. Twenty-one women and 21 men completed land-and-cut manoeuvres on their dominant limb as well as their nondominant limb. Three-dimensional kinematics and kinetics were calculated bilaterally for the entire stance phase of the manoeuvre. Women performed land-and-cut manoeuvres with altered hip motions and loads as well as greater knee abduction at touchdown compared to men. Dominant limb land-and-cut manoeuvres where characterised by decreased hip flexion at touchdown as well as decreased hip flexion and adduction range of motion compared to nondominant land-and-cuts regardless of sex. The observed sex differences are consistent with previous research regarding mechanisms underlying the sex disparity in anterior cruciate ligament injury rates. However, observed differences regarding limb dominances appear somewhat arbitrary and did not suggest that the dominant or nondominant limb would be at increased risk of anterior cruciate ligament injury. 相似文献

This research is designed to provide information for participants, facilitators and policy makers in the area of Extended Schools. Its salient purpose is to investigate and examine the feelings, beliefs and attitudes of teachers and parents involved in the development of the Extended Schools project in Northern Ireland. The Extended Schools project was formally launched by the Northern Ireland Secretary of State on 7 March 2006, and aims to provide a wide range of services and activities in school with the intention of helping to meet the needs of children, their families and the wider community. The qualitative approach was deemed the most appropriate methodology for gathering data. 相似文献

This study report deals with the transition of the young adult through the pre‐leaving years, early work experience (or the lack of it), and social adjustment. It goes on to examine the potential role of network and regional broadcasting.
Initially, it reflects widespread concern about the academic/vocational balance in secondary education, the realism of careers preparation, the unemployed casualty figures, and the quality of school/home and education/industry exchanges. It notes the lack of communication between the agencies involved in their parallel fieldwork, and with the families facing individual dilemmas in education, work opportunity and adolescent disillusion.
In this context, broadcasting's prime role is access to the individual in the family setting where informed home debate and decision‐making are critical. Although specialised programme output has increased, how much relevant help is provided at regional and local level? How available is the essential follow‐up in referral centres, advisory services, print material, etc.? What about parents, teachers, employers, training supervisors and the like who might share their experience and initiative in local self‐help projects? Can general public awareness be stimulated to community action?
But if regional and local stations are to do more, there are many policy and logistic questions to be answered ‐ in partnership with official and voluntary agencies and within a network/regional plan. Although there may be a consensus that the broadcast media could play a valuable part, the question remains ‐ “From whom will the initiative come towards linkage and partnership?”. 相似文献

This article presents and discusses a perspective on the implications of the Lisbon Process for education and training in a selected group of partner countries of the European Union — the Western Balkans (Albania, Bosnia and Herzegovina, Croatia, The Former Yugoslav Republic of Macedonia, Serbia and Montenegro). It presents the reflections of a member of staff of the European Training Foundation responsible for managing the six country regional project underway since 2003 on developing strategies for national qualification frameworks. The reflection aims to assess the potential contributions of a major strategy of the European Union on the reform processes underway in the social and economic transitions in the Western Balkans. It draws on the broader experience of the Foundation in supporting reforms in vocational education and training systems. Qualification reform is taken as an illustrative example of the use, relevance and constraints of EU ‘processes’ in accompanying education and training reform. Although the Copenhagen process partially provides a broad structure and there is a shared history between the countries of the region, each country is sufficiently different in its local contexts to suggest that the manner and pace of adoption will diverge. The emphasis on further development to suit local circumstances essentially gives partner countries an approach or set of tools with which they can shape and form their own initiatives with some confidence that the result will be in line with general European trends. 相似文献

Experienced searchers can help their patrons find the "best" by employing any of several techniques which might filter search results. Using a sample search on Alzheimer's Disease, this article describes and illustrates the following five objective indicators which might be considered signs of quality: methodological rigor, document attributes, peer review, journal reputation, and filtering at input. Sample techniques and results are presented for six databases: MEDLINE, CINAHL, EMBASE, SAMM, CCML, and JWAT. Understanding of the patron's need and knowledge of the structure and contents of the database will determine when each should be applied to search results. 相似文献

At times, there are reasons for authors to make a formal statement of retraction of work they publish in biomedical journals. This study examines 235 retracted articles and looks at the reasons for these retractions and citations to the articles subsequent to retraction. The primary reasons for retraction are error of various kinds (such as problems with method or sample, including contamination of samples) and misconduct. The 235 articles are cited a total of 2,034 times after retraction. This set of citations can be divided into two groups: citations that appear in journals included in the Abridged Index Medicus and those that appear in other journals included in MEDLINE. While most of the citations in these two groups of journals can be categorized as "implicitly positive," 275 make explicitly positive mention of retracted articles. The implications for continued citation for biomedical research and clinical practice are discussed. 相似文献

The Internet has created new opportunities for librarians to present literature search results to clinicians. In order to take full advantage of these opportunities, libraries need to create locally maintained bibliographic databases. A simple method of creating a local bibliographic database and publishing it on the Web is described. The method uses off-the-shelf software and requires minimal programming. A hedge search strategy for outcome studies of clinical process interventions is created, and Ovid is used to search MEDLINE. The search results are saved and imported into EndNote libraries. The citations are modified, exported to a Microsoft Access database, and published on the Web. Clinicians can use a Web browser to search the database. The bibliographic database contains 13,803 MEDLINE citations of outcome studies. Most searches take between four and ten seconds and retrieve between ten and 100 citations. The entire cost of the software is under $900. Locally maintained bibliographic databases can be created easily and inexpensively. They significantly extend the evidence-based health care services that libraries can offer to clinicians. 相似文献

The authors ask whether full-text versions of medical journals are available for searching sooner than their biblographic counterparts. The journals in question are those found in the Comprehensive Core Medical Library (CCML) from BRS Information Technologies and in Mead Data Central's MEDIS Current Journal Files. All journals in these two files are full-text, and neither file contains any indexing features. Update schedules for the full-text version of the MEDLINE journals in each of these files were compared with the most recent issue available in the National Library of Medicine's (NLM) MEDLINE on five different dates. The data revealed substantial fluctuation in comparative currency for MEDIS/MEDLINE over the period of the test. On the date of the last snapshot, June 8, 1990, MEDLINE and MEDIS were offering the same currency for 43% of the journals, and MEDIS was providing first access to 29% of the titles. The CCML/MEDLINE comparison showed less variation. In the last snapshot MEDLINE and CCML were providing access to the same issue for 36% of the journals, and CCML was offering first access to 14%. Prior to publication, this paper was submitted to all three vendors for comment. Significant portions of their responses are quoted. 相似文献
