ABSTRACTIntroduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required. 相似文献

The effect of technology-enhanced learning (TEL) strategies in higher education has arguably been transformative despite the not-insignificant barriers existing in this context. Throughout the discourse very little attention has been paid to those primarily responsible for this implementation—academic teaching staff. This paper aims to highlight the impact of academic workload allocations, an often silent barrier to the uptake of TEL strategies in higher education. We will discuss the effects of academic identity and culture, preferential time allocation to associative activities, academic technological capacity, university policies and workload and funding models on the uptake, and implementation on TEL in higher education. Our aim is to highlight the risks to staff, students and institutions should these concerns not be addressed and to propose a model for utilisation by all staff responsible for implementing flexible workload models supportive of further implementation of TEL strategies across the sector. 相似文献

This discussion article seeks to uncover those aspects of nontraditional programs which carry the highest priority for students. Alternative graduate education is explored from the perspective of one student who has participated in two nontraditional programs. Highlighted issues include: changing roles and responsibilities for both faculty and students, problems with shared decision-making, the need for team building and problem solving, and the importance of maintaining open channels of communication.Dr. McDonnell recently completed the Doctor of Education Degree in Organization and Leadership at the University of San Francisco, San Francisco, California. Her Master of Arts Degree in Human Development was earned through St. Mary's College, Winona, Minnesota. She now lives in Bennettsbridge, Co Kilkenny, Ireland. 相似文献

Clinical discourses from the domains of medicine and psychology exert a powerful influence on theory and practice in special education. These discourses first define disability as ‘an individual human condition’ and locate ‘the problem’ in the physiological and psychological characteristics of the individual. Second, they privilege the role of experts and exclude the perspectives of disabled people themselves. In spite of considerable criticism, psycho-medical definitions of and responses to disability have been incorporated into educational legislation in Ireland and continue to dominate policy development in special education. The real danger of failing to address these deep structures in special education is that exclusion and marginalization will be reproduced even in well-intentioned and well-supported programmes. 相似文献

This paper reports on an action research project into the development of a ‘democratic feedback model’ with students on an education studies programme at a post-1992 university in the UK. Building on work that has explored the dialogic dimensions of assessment and feedback, the research explored the potential for more democratic practice in this area. Although much learning and teaching on the programme in question took a collaborative and dialogic approach, assessment and feedback were modelled entirely differently, around the concept of an ‘expert’ marker and ‘novice’ marked. The findings of the research indicate the elements necessary for ‘democratic feedback’, and illustrate the emotional impact of moving from more transmission-based models, grounded in notions of expertise, towards democratic practice. They also highlight the ways in which such work can alert students to the imperfect, messy and human nature of the assessment process. Although the model has limited applicability in its extant form, its constitutive elements might be usefully incorporated within existing practice to promote democratic learning. 相似文献

After a series of instrument development studies, a mail survey was conducted with 196 randomly selected family day care providers (FDCPs) and child care center workers (CCCWs) residing in the state of Maryland (response rates were 76.6% and 70.5%, respectively). Embedded in the instrument were three job stress scales, specific to child care workers, measuring job demands, job control, and job resources. Extensive psychometric testing of the three 17-item instruments demonstrated several areas of strength. The job demands scale, because of its breadth of stressors covered, fared slightly worse on indicators of reliability (alpha = 0.77; mean interitem correlation [MIC] = 0.17; item-to-total correlations [ITCs] = 0.14 to 0.49) than did job control (alpha = 0.88; MIC = 0.31; ITCs = 0.26 to 0.69) and job resources (alpha = 0.89; MIC = 0.35; ITCs = 0.32 to 0.70). Known groups validity was demonstrated through a conceptually meaningful pattern of differences between FDCPs and CCCWs. Construct validity for all three scales was demonstrated by a pattern of stronger correlations with conceptually similar versus dissimilar instruments. Average correlations with similar versus dissimilar instruments were: job demands, 0.54 versus 0.24; job control, 0.74 versus 0.30; and job resources, −0.53 versus 0.30. Similar to the reliability analysis, results of factor analysis were stronger for job control and job resources than for job demands. 相似文献

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research. 相似文献
