This study examined the separate and combined effects of heat acclimation and hand cooling on post-exercise cooling rates following bouts of exercise in the heat. Seventeen non-heat acclimated (NHA) males (mean ± SE; age, 23 ± 1 y; mass, 75.30 ± 2.27 kg; maximal oxygen consumption [VO₂ max], 54.1 ± 1.3 ml·kg^?1·min^?1) completed 2 heat stress tests (HST) when NHA, then 10 days of heat acclimation, then 2 HST once heat acclimated (HA) in an environmental chamber (40°C; 40%RH). HSTs were 2 60-min bouts of treadmill exercise (45% VO₂ max; 2% grade) each followed by 10 min of hand cooling (C) or no cooling (NC). Heat acclimation sessions were 90–240 min of treadmill or stationary bike exercise (60–80% VO₂ max). Repeated measures ANOVA with Fishers LSD post hoc (α < 0.05) identified differences. When NHA, C (0.020 ± 0.003°C·min^?1) had a greater cooling rate than NC (0.013 ± 0.003°C·min^?1) (mean difference [95%CI]; 0.007°C [0.001,0.013], P = 0.035). Once HA, C (0.021 ± 0.002°C·min^?1) was similar to NC (0.025 ± 0.002°C·min^?1) (0.004°C [?0.003,0.011], P = 0.216). Hand cooling when HA (0.021 ± 0.002°C·min^?1) was similar to when NHA (0.020 ± 0.003°C·min^?1) (P = 0.77). In conclusion, when NHA, C provided greater cooling rates than NC. Once HA, C and NC provided similar cooling rates.  相似文献   

Broadway productions and the value of a Tony Award     

Melissa Boyle  Lesley Chiou 《Journal of Cultural Economics》2009,33(1):49-68

This article investigates the effect of a Tony nomination or win on the demand facing a Broadway production using a panel of weekly revenues for Broadway productions from 1996 to 2007. Our results indicate that the effect of a nomination or win is positive in the week of the announcement and gradually increases in successive weeks, presumably due to publicity and word-of-mouth. Winners experience an increase in demand as late as 1 year later when awards are publicized for the following season. Moreover, nominees that do not win the award are penalized heavily in the weeks following the Award announcements. We find that winning a Tony Award increases a production’s revenues by 12% in the week immediately following the Awards.

Curriculum reform and choice of science: Consequences for balanced and equitable participation and achievement     

Lonie J. Rennie  Lesley H. Parker 《科学教学研究杂志》1993,30(9):1017-1028

In 1988, most schools in Western Australia adopted a Unit Curriculum structure in the first three years of high school, following piloting of the scheme in seven schools in 1987. The goais of the Unit Curriculum are stated to be excellence, equity, and relevance, and one of its key features is the increased flexibility students have in making their subject selection. This article reviews the science enrollment and achievement patterns of males and females studying in the pilot schools in 1987, and for the first three years of the operation of the Unit Curriculum in 1988, 1989, and 1990. The data indicate that lowering the age for subject choice is associated with a reduction in the amount of science studies, especially by females, and with the early manifestation of sex-stereotyped subject selection. It appears that if early sex stereotyping is to be avoided, then students need to be provided with more structure in their selection of units. This article emphasizes the need for all involved in system-wide curriculum change to be fully informed of the potential benefits and dangers of curriculum models which allow wide flexibility, especially where curriculum change affects students' “choice point”.  相似文献

Differentiation and its Problems: the views of primary teachers and curriculum support staff in Northern Ireland     

Brian McGarvey  Valerie Morgan  Stuart Marriott  Lesley Abbott 《Educational studies》1996,22(1):69-82

This paper identifies a range of problems associated with putting differentiation into practice. The opinions of head teachers, subject co‐ordinators, and teachers were sought, as well as those of the curriculum support staff in the Education and Library Boards on the extent to which these problems affected primary schools in Northern Ireland, and case‐studies illuminated these views. The results showed that the curriculum support staff regarded most problems in differentiation in a more serious light than the schools themselves did, but there was agreement on the acute lack of time to deliver a differentiated curriculum, on the shortage of human resources and on the difficulties with new assessment methods.  相似文献

Developing inclusive schools: the pivotal role of teaching assistants in promoting inclusion in special and mainstream schools in Northern Ireland     

Anne Moran  Lesley Abbott 《欧洲特需教育杂志》2013,28(2):161-173

This paper focuses on the vital part played by teaching assistants in developing inclusive practices in Northern Ireland schools. In the case of mainstream schools, this means assisting with the integration of pupils with learning difficulties in regular classrooms. In the case of special schools, teaching assistants are required to have the knowledge and skills both to cope with children and young people who have a broad range of intellectual, physical and emotional difficulties, and to promote inclusion and participation beyond the school environment. However, the teaching assistant's position with respect to qualifications, professional development, conditions of employment and career structure, considering the greatly increased and varied demands placed upon them, has not been satisfactorily resolved at national level over some 30 years. By obtaining the views of practitioners in special and mainstream schools in Northern Ireland, the paper shows that the twin needs remain of improving teacher training and in-service training in the management of other adults in the classroom, and of enabling teachers to clarify fully the roles and responsibilities of the teaching assistant to promote an inclusive learning environment.  相似文献   

How are action researchers contributing to knowledge democracy? A global perspective     

Lesley Wood  Mary McAteer  Jack Whitehead 《Educational Action Research》2019,27(1):7-21

ABSTRACT

Although action research has been widely recognized as an appropriate methodology for promoting the democratization of knowledge, it is not always conducted from an emancipatory and transformative paradigm. Using AR in a technical way, renders it no more than a researcher-driven, problem-solving heuristic that perpetuates the intellectual colonization of local knowledge. This begs the question: how can action researchers work in ways that are contextually and culturally relevant, and generate knowledge that enables people to take control of improving their own lives as they see fit? This paper presents a thematic analysis of the narrative reports from seven participatory workshops held around the world for the purpose of dialoging around this and related questions. Findings indicate that, generally, action researchers are indeed facing challenges on many personal, institutional and epistemic levels as they endeavor to promote knowledge derived from the principles of authentic participation and dialogue with those whom it is intended to benefit. However, the analysis also reveals creative responses of practitioners to these challenges. In keeping with the special issue theme, we offer this analysis as a starting point for further discussion around how we can mobilize knowledge for equitable social progress.  相似文献   

The global classroom: advancing cultural awareness in special schools through collaborative work using ICT     

Lesley Abbott  Aidan Mulkeen  Nigel Metcalfe 《欧洲特需教育杂志》2013,28(2):225-240

This paper reports research on cross‐national collaboration through Information and Communications Technology (ICT) within the statutory curricula of 10 special schools in Northern Ireland and the Republic of Ireland. Working in north–south paired classes, the pupils carried out joint tasks using asynchronous computer conferencing and videoconferencing. The full spectrum of learning difficulty and disability was represented amongst the participating pupils. Interviews were conducted to elicit the views and experiences of the teachers in the 2002/03 cohort. The main aims were to discover whether cultural awareness developed through joint tasks using the two technologies, if computer conferencing improved literacy and ICT skills, and if videoconferencing enhanced oral communication. The results showed that cultural awareness developed as far as cognition allowed, when pupils in partner schools became aware of similarities as well as differences. Those with sufficient keyboard ability benefited from computer conferencing and ICT competence improved, but the much preferred medium for collaborative, inter‐school work was videoconferencing. All but the most dependent pupils could participate, and valuable, transferable social and communication skills were acquired.  相似文献   

Agents for change: policy and practice towards a more gender‐inclusive science education     

Jan Harding  Lesley H. Parker 《International Journal of Science Education》2013,35(4):537-553

A range of initiatives aimed at a more gender‐inclusive science curriculum has developed in many countries. In this paper five countries are used to illustrate these developments. They have occurred usually in the context of relevant policy statements, but sometimes in the absence of a policy, through activists, often outside the school system. At times policies developed within the education system act in opposition to a change towards greater gender equity in science education. However, when policies are in place and made visible, and where feedback and adequate monitoring are required change has occurred. The successful incorporation of gender equity awareness and practices into the professional role and practice of teachers requires adequate resources to support change.  相似文献
