Currently, very little is known about the impact of short- or long-haul air travel on the sleep and wellbeing of wheelchair basketball athletes. Eleven national wheelchair basketball athletes wore actigraphy monitors prior, during, and after air travel to the United Kingdom. Upon arrival, participants rated their subjective jet-lag, fatigue, and vigor. Individuals traveled to the United Kingdom from different locations in Australia, the United States, and Europe and were categorised according to travel length [LONG (up to 30.2 h) or SHORT (up to 6.5 h)]. Linear mixed models determined effects of travel length on sleep and subjective ratings of jet-lag, fatigue, and vigor. During competition, subjective fatigue and jet-lag were substantially higher (ES = 0.73; ±0.77) and (ES = 0.57; ±0.60), subjective vigor was lower (ES = 1.94; ±0.72), and get-up time was earlier (ES = 0.57; ±0.60) for LONG when compared to SHORT. Travelling greater distances by airplane had a larger effect on subjective ratings of jet-lag, fatigue and vigor, rather than sleep. Irrespective of travel group, sleep and subjective responses were compromised, reflecting the travel requirements, competition-mediated influences, and/or due to a change in environment.  相似文献

Abstract

In two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design.  相似文献

Abstract

Although it is acknowledged that appropriate breast support during exercise is important, no published literature has assessed breast support usage in a cohort of female marathon runners. This study aimed to identify sport bra use and perceived importance of sports bra use in female marathon runners. Bra satisfaction, incidence of bra related issues and factors that influence the appropriateness of sports bras were also investigated. A 4-part, 30-question survey was administered to 1397 female runners at the 2012 London marathon registration and via an online survey. In total 1285 surveys were completed. Sports bra use and its perceived importance was high, however was lower in moderate compared to vigorous activity, and lower in participants with smaller breasts. Seventy-five per cent of participants reported bra fit issues. The most common issues were chaffing and shoulder straps digging in, with a higher incidence of issues reported by participants with larger breasts. Use of professional bra fitting was low, and perceived knowledge of breast health was poor. Engagement with sports bra use is high although sports bra design could be improved to alleviate bra fit issues experienced by female runners. Educational initiatives are needed to ensure females are informed regarding the importance of breast support and appropriate bra fit during activity.  相似文献

International knowledge markets rely heavily on a ready supply of highly mobile doctoral students, many of whom are from the global South, to bring in revenue. The supervision of these PhD students, however, can reproduce neo-colonial knowledge relations, often in subtle ways. In settler nations, international PhD students may find that they are assigned subaltern status in their university departments and this can have a significant impact on their learning. This paper explores the experiences of a group of international PhD students in a social science faculty in a New Zealand university during the first two years of their doctoral studies. It examines how they responded to the displacement of their cultural values and priorities, the way they navigated intercultural engagements with supervisors, and their ensuing relationships with indigenous and ethnic allies in the faculty. Despite considerable pressure to conform to the dominant modes of academic knowledge production that characterise universities in settler nations, it is concluded that international students find ways of speaking out, often in highly coded forms, that complicate their subaltern academic status.  相似文献

Critical thinking is a highly valued outcome of university study, although its nature is difficult to define. Most students are not directly taught critical thinking, but are expected to display it in at least some of their assignments. We do not know much about student perceptions of their development as critical thinkers in their degree programs. This paper presents research into student perceptions of instruction in critical thinking and aspects of its development as they study in an undergraduate degree program in agriculture. Twenty‐one students across four years of study were interviewed. They received direct instruction in critical thinking only in the first year of study, and the literature review emerged as a key genre in which critical thinking was perceived to be important by later‐year students. The final sections highlight the importance of considering the disciplinary contexts in which students develop their critical thinking, and of preparing them for transfer to post‐study contexts.  相似文献

The work of the late Barbara Cooney may be divided into three distinct periods: 1940–1958, a stage of work primarily in scratchboard; 1959–1980, a period in which she experimented broadly; and 1980–1999, the folk art phase in which she worked largely in acrylics. This article explores the development of each stage in detail, and reflects on Cooney's strengths and weaknesses as well as her overall contribution to picture book art. It also explores the contribution of limitations, both technical and artistic, to the general impact of Cooney's work and investigates some of her ideological as well as technical developments.  相似文献

Here, we argue that action learning (AL) has been evolving into different variations, whose respective advocates appear to concentrate on one of the several components inherent in Revans’ formulation of AL as L?=?P?+?Q. They do this – sometimes inappropriately – to the virtual or relative exclusion of other aspects, and this has consequences for the outcomes and impact of the AL process. In an attempt to delimit the boundaries between various versions and indeed to identify what Johnson [2010. A framework for the ethical practice of action learning. Action Learning: Research and Practice 7, no. 3: 267–283] called ‘inauthentic’ AL, we have been developing our ideas for a scanning device or framework. We refer briefly to some of the theoretical underpinnings of this framework. We then introduce a fresh taxonomy to explain and illustrate features of five principal variations of emphasis in AL that we have identified. The aim of this framework is to help stakeholders to work towards selecting and co-creating the most appropriate variation of ‘authentic’ AL to suit their unique set of circumstances at any given time. We outline the likely outcomes of each respective variation if taken to extremes and conjecture about their implications. This taxonomy should also help one to reduce the mystique and confusion that often surround AL while acknowledging its complexity. We suggest that by taking advantage of insights provided by this framework, purchasers and potential AL set members in particular are more likely to participate in learning conversations that lead to more informed decisions and actions to address or adjust their respective interests and needs. In conclusion, we identify some areas for further research and development.  相似文献

Over the past 20 years most countries, particularly developing countries, have seen a large increase in the number of students seeking higher education. A consequence of this growth is increasing pressure on teaching staff and institutions, usually resulting in, among other effects, increased class size. Large classes of between 300 and 1,000, and even more, at the undergraduate level are not uncommon in a number of countries (Mulryan-Kyne in Teach High Educ 15(2):175–185, 2010). Large classes are often perceived as one of the major obstacles to the attainment of quality education. Despite the difficulties associated with teaching and learning in large classes, they remain a reality in many countries affecting learners across all levels of the education system and are often the only perceived option available to meet growing demand for higher education in Sub-Saharan Africa (Mohamedbhai in The effects of massification on higher education in Africa. Report from the Working Group on Higher Education of the Association for the Development of Education in Africa, 2008). We contend that the challenges of delivering large classes can be confronted, and in many ways diminished, through the use of current and emerging technologies and enhanced faculty development. In this expository paper, we present findings from project activities focused on higher education faculty development and capacity building. The findings include both formative and summative development activities, as well as data collected in faculty professional development workshops and the results of two surveys. We use these data to lay out issues, challenges (e.g., skills, resources, logistics—including poor campus infrastructure), and opportunities (e.g., mobile capacity, distance tools such as Moodle) of large class pedagogy using a design-based research framework.  相似文献
