Comparison of power and EMG during 6-s all-out cycling between young and older women

Abstract To investigate the effects of ageing on the neural control strategies governing sprint cycling on a friction-loaded cycle-ergometer, 10 older (aged 70-83yr) and 8 young (aged 19-35yr) healthy women completed seven 6-s all-out cycling trials against varying loads. Root mean square (RMS), median frequency and muscle fibre conduction velocity were determined from the vastus lateralis of the dominant limb during each pedal stroke. Peak power was 43% lower in the older group compared to the younger (p??0.05). ΔRMS from the first to the sixth second during each trial was found to increase significantly with the development of power output in both groups (p?相似文献   

Reading the Local and Global: Teaching Literature in Secondary Schools in Australia

Recently Australia has witnessed a revival of concern about the place of Australian literature within the school curriculum. This has occurred within a policy environment where there is increasing emphasis on Australia’s place in a world economy, and on the need to encourage young people to think of themselves in a global context. These dimensions are reflected in the recently published Australian Curriculum: English, which requires students to read texts of ‘enduring artistic and cultural value’ that are drawn from ‘world and Australian literature’. No indication, however, is given as to how the reading and literary interpretation that students do might meaningfully be framed by such categories. This essay asks: what saliences do the categories of the ‘local’, the ‘national’ and the ‘global’ have when young people engage with literary texts? How does this impact on teachers’ and students’ interpretative approaches to literature? What place does a ‘literary’ education, whether conceived in ‘local’, ‘national’ or ‘global’ terms, have in the twenty-first century?     

The mentoring dilemma: guidance and/or direction?

Abstract

How effective is your mentoring programme? How does the nature of a mentoring programme influence outcomes? By looking beneath the process and practice, an examination, analysis and classification of the nature of current real‐life mentoring practice is made and a template for the identification of your own project is presented.     

Accelerating knowledge production on educational leadership and management in East Asia: a strategic analysis

This paper discusses a strategy for accelerating the development of a regionally grounded knowledge base on educational leadership and management in East Asia. The study reviews data on patterns of knowledge production in East Asia, and employs the findings in the development of a strategy for increasing knowledge production. The study concludes that a suitable coordination strategy for the region should incorporate formal and informal strategies, be intermediate in scale and organised around a common research agenda. The authors propose that the substantive findings and the method of strategy analysis may also be relevant for academic leaders in other developing regions of the world.     

THE RANGE AND IMPACT OF LEA BEHAVIOUR SUPPORT PLANS

The requirement that all Local Educational Authorities in England and Wales produce plans for their provision for ‘pupils with problems’ has resulted in a wide range of responses. The data in this paper are drawn from a sample of Behaviour Support Plans and the responses of a group of individuals (teachers) closely affected by them. The plans are firstly analysed using an evaluation framework developed from Circular 1198, which announced the Behaviour Support initiative. The paper then draws on the evaluatory critiques of teachers who work in both mainstream and special (EBD) schools; these were obtained by interview. Data suggest that, BSPs generally follow the pattern of guidance provided in the Circular, although there are several notable omissions in some plans. There are wide variations in the way in which BSPs have been perceived by teachers working with children with behaviour problems; importantly, these views regard some BSPs as, in part, little more than reiterations of previously attempted initiatives.     

Sex and relationship education and the media: an analysis of national and regional newspaper coverage in England

Newspapers are recognised as a major source of factual information. The media representation of issues related to teenage pregnancy is important to policy makers and those delivering related interventions. This is particularly so in relation to issues which may be seen as sensitive by the public, such as sex and relationship education (SRE). Despite general recognition of the importance of the media in communicating to the public, there is an absence of satisfactory tools with which to evaluate newspaper reports, particularly so in the field of SRE. In this paper we present a systematic examination of newspaper articles related to SRE from September 2000 to September 2002, in the national and regional press in England. Our analysis has highlighted some important distinctions between newspaper type, spokesperson and region. This paper concludes that a pro‐active strategy of directly contacting high circulation newspapers with a view to positively influencing the tone of relevant articles and reports would be of considerable benefit to those involved in SRE, teenage pregnancy and related interventions.
