The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a brief two item measure and the International Physical Activity Questionnaire—Short Form questionnaires on day 1 and 9. Correlations between self-reported and accelerometer derived moderate-to-vigorous physical activity levels were moderate for the International Physical Activity Questionnaire—Short Form, while poor for the single-item measure and the a brief two item measure. The agreement level was high with the International Physical Activity Questionnaire—Short Form (77.4%) and moderate for both the single-item measure (45.2 %) and a brief two item measure (44.5 %). The intraclass correlations between the two administrations were moderate to strong across all measures (0.52–0.70) in 133 participants. The International Physical Activity Questionnaire—Short Form is the most suitable of these three self-report instruments for use with this population due to higher correlations and levels of agreement with accelerometry. 相似文献

This paper investigates the determinants of R&D expenditure using a sample of UK listed companies with the highest spend from 2000 to 2005. We investigate the effect of corporate governance and ownership on R&D, using panel data. The results provide some evidence that more governance tends to depress R&D activity, a finding that is robust to whether a composite or disaggregated index of governance is used. One innovation of the paper is that we treat agency and finance effects interactively. The ownership stake of the CEO appears to be supportive for R&D. 相似文献

This paper provides a detailed analysis of student teachers’ lay theories of teaching, and teaching identities, and assesses their implications for student teachers’ and teachers’ professional development. Understanding the critically formative influences in student teachers’ lives and the extent to which these are reinforced, reproduced and recast in and through student teachers’ lay theories has major significance for initial teacher education and ongoing professional development of teachers. The paper draws together the threads of this analysis around issues of teaching identities, their formation, continuity, tenacity and openness to change and assesses, through a postmodern lens, their implications for professional development of student teachers, beginning teachers and experienced professionals. 相似文献

This article describes a four-year project undertaken to develop a set of performance tasks that could be used for assessing hands-on science in Irish primary schools. It begins by considering some of the literature on performance assessment and concludes with a discussion on the potential of the tasks to support teaching and learning in science. The main body of the article is structured to reflect the five phases of the research project itself. In phase one, science assessments used in a variety of educational systems in Australia, Canada, New Zealand, the United Kingdom and the United States were located and catalogued. In phase two, approximately 170 performance tasks were selected and adapted by the authors to suit the requirements of the Irish primary science curriculum. In phase three, a purposive convenience sample of teachers evaluated the extent to which the tasks (a subset of 67) were suitable for use at different grade levels. The teachers’ feedback was used to amend tasks. In phase four, the researchers observed 11 different tasks being implemented in classrooms. The eleven teachers involved were interviewed about their experiences immediately afterwards. Again, based on the outcomes of this study, changes were made to the tasks. The fifth phase of the project, due to be completed in 2006, will involve the dissemination of 124 of the tasks to teachers via a booklet and a CD-ROM. Future prospects relating to other elements of the project such as Web-based resources, professional development courses and exemplars of performance are also discussed. 相似文献

A growing body of work suggests that negative stereotypes of, and associations between, falling, fear of falling, and ageing, may mean that older adults reject falls information and advice. Against a widely accepted backdrop of demographic ageing in Europe and that alleviating the impacts of falls and fear of falling are pressing health care matters, this is a critical issue. This paper describes a recent peer learning and sharing strategy that set out to iteratively produce a series of short audio visual discussion programs on falling and fear of falling. Key outcomes included older adults appreciating peer group sharing as an acceptable way of opening up the silence surrounding falls incidences, enjoying participating in a problem solving strategy, and emphasizing that falls prevention is not just their responsibility. Outcomes suggest that peer learning and sharing are valuable falls and fear of falling support strategies. 相似文献

While ‘paradigm wars’ have raged internationally during the past decade in particular, the research community, qua community in the Irish context has been largely silent on these important issues. This paper provides a synthesis of key aspects of these international discourses against a brief historical backdrop of the field of educational research. Thereafter, this theoretical lens is used to interrogate the more than 200 papers published in Irish Educational Studies (IES) over a period of 10 years: 1996–2006. This analysis seeks to establish the relative health and quality of educational research in the Irish context, and in the third section of the paper, this analysis is the basis for discussion of lessons that may be learned from insights and understandings gained. The paper concludes that a more systematic and comprehensive review of educational research funding in the Irish context would be particularly apposite and timely, while also advocating the necessity for a comprehensive educational research policy and the creation of a national educational research council. In the absence of such endeavours, research is likely to remain fragmented, small scale and easily dismissed by policy-makers, thus enabling advocacy rather than evidence and research generated elsewhere to overly-influence educational reform, while failing to enhance and extend a comprehensive ‘native’ research literature, a vibrant research culture, while funding and systematically supporting and developing the next generation of educational researchers. In the absence of policy and funding, quality and capacity will continue to falter in a more complex, sophisticated interdependent world. 相似文献

In a climate of accountability and performativity, do teachers experience CPD provision as an externally imposed demand for conformity, compliance, to be accountable, or as a personal and professional rejuvenation that enhances their sense of professional responsibility? Through a qualitative study of secondary schools in England, this paper critically scrutinises the experiences of teachers in five case study schools to create a composite picture of the realities of their lives as they are buffeted and shaped by performativity while also examining the extent to which their CPD experiences may be perceived as enhancing their sense of professional responsibility. Critical analysis of the evidence suggests that the language of accountability is pervasive, and its logic gains currency by being imposed throughout schools where there is limited space to craft an alternative, thus performativity and conformity are more likely than dissent while enhancement of a sense of professional responsibility is rendered more difficult, marginalised if not entirely silenced. The concluding discussion raises critical questions regarding the health of the profession from a policy and practice perspective if the language of professional responsibility continues to be weakened or diluted by being filtered through the closely woven weave of externally prescribed accountability criteria. It concludes that the language and logic of professional responsibility is vitally necessary in provoking alternative discourses on the future of the profession and the quality of teaching, learning and leading in schools within and beyond the confines of the study. 相似文献

This article engages with Atkinson’s recent criticisms of concepts of collective habitus, such as ‘institutional’ and ‘familial’ habitus, in order to defend their conceptual utility and theoretical coherence. In so doing we promote a flexible understanding of habitus as both an individual and a collective concept. By retaining this flexibility (which we argue is in keeping with the spirit of Bourdieuian philosophy) we allow for a consideration of the ways in which the individual habitus relates to the collective. We argue that, through recognition of the complexity of the interrelated habitus of individuals, collective notions go beyond individualist accounts that perceive only the relational aspects of the individual with the social field. Our approach allows us to consider social actors in relation to each other and as constitutive of fields rather than as mere individuals plotted in social space. These arguments will be woven through our responses to what Atkinson calls the three fatal flaws of institutional and familial habitus: namely, homogenisation, anthropomorphism, and substantialism. 相似文献

Player-to-player contact inherent in many unhelmeted sports means that head impacts are a frequent occurrence. Model-Based Image-Matching (MBIM) provides a technique for the assessment of three-dimensional linear and rotational motion patterns from multiple camera views of a head impact event, but the accuracy is unknown for this application. The goal of this study is to assess the accuracy of the MBIM method relative to reflective marker-based motion analysis data for estimating six degree of freedom head displacements and velocities in a staged pedestrian impact scenario at 40 km/h. Results showed RMS error was under 20 mm for all linear head displacements and 0.01–0.04 rad for head rotations. For velocities, the MBIM method yielded RMS errors between 0.42 and 1.29 m/s for head linear velocities and 3.53–5.38 rad/s for angular velocities. This method is thus beneficial as a tool to directly measure six degree of freedom head positional data from video of sporting head impacts, but velocity data is less reliable. MBIM data, combined in future with velocity/acceleration data from wearable sensors could be used to provide input conditions and evaluate the outputs of multibody and finite element head models for brain injury assessment of sporting head impacts. 相似文献
