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   

Getting Generation Y to attend: Friends,interactivity and half-time entertainment

People from Generation Y, given their number and stage in the family life-cycle, represent a key emerging audience for major sports. The study focussed on the effect of friends and half time enhancements on likely attendance at matches. The sport domain was the Australian Football League (AFL), the elite Australian rules football competition. The enhancements being tested were half-time entertainments based on performers from well-known television talent shows, Australian Idol and It Takes Two. Scenarios with and without interactive participation, based on short messaging service (SMS) messages, were tested. The study used a general population sample of 909 Generation Y people in a traditional AFL market and one where AFL is not the major winter competition. Previous attendance and sport orientation were the major influences on attendance at major sports, including the AFL. Friends influenced likely attendance at a game, but no effects were found for half-time entertainments. People who attended matches with friends typically had social activities before and after the game. This suggested that one promotional strategy to expand existing markets was to find and engage the social networks of existing fans, making sport attendance a broader part of an overall social event.     

Public journalism公共新闻——A reply to critics对批评的回应

公共新闻运动在新闻学者和新闻从业者中是个颇具争议性的话题.它始于上世纪90年代早期,是对政府和公民、新闻机构和受众间日益扩大的分歧的回应.也就是政治选举中选民参与的下降,更普遍的说,是公民参与本地社区事务的衰退,这被视做公民普遍退出民主进程的例证.     

Whose place,whose history? Outdoor environmental education pedagogy as ‘reading’ the landscape

Outdoor education practice around the world occurs in diverse circumstances, environments and cultures. The application of outdoor education to specific cultural and environmental issues in particular places and communities has received little attention in research. While research in fields such as cultural geography has addressed the relationships between cultures, communities and geographical places, this is largely overlooked in outdoor education research. In this paper I draw on literature from cultural history and environmental history to explore how these disciplines might inform outdoor education research and pedagogy that addresses current cultural and environmental issues of specific communities and geographical places. With the aid of the rhizome metaphor for (re)structuring knowledge, I use examples from my practice in Australia to demonstrate how reading the landscape and the use of stories, or historical accounts, can assist outdoor educators and participants to probe and reflect on the relationships between personal experience and the complex cultural-ecological processes that have shaped the places in which we live and work.     

Integrating Case Studies in Engineering Mathematics: A response to SARTOR 3

Case studies have long been used to support the mathematics education of undergraduate engineers. Changes in the mathematical ability of entrants to engineering programmes and, indeed, the changing nature of many of the programmes themselves indicate the need to make the students' mathematical experiences more 'user friendly'. We describe here an approach which uses case studies, not as illustrations of applications of mathematics after a mathematical topic has been discussed, but in a fully integrated central role as vehicles for whole group discussion from which the students 'discover' the necessary mathematics which is taught subsequently. Not only is the 'carrot' of the application then central to their learning, but the need for the mathematics being taught is also clearly demonstrated. This approach has been tried with a group of 50 first year engineers. The effects on student motivation, ability and knowledge retention are discussed together with an indication of the Integrated Case Studies which were used.     

The happy artist: an empirical application of the work-preference model

The artistic labor market is marked by several adversities, such as low wages, above-average unemployment, and constrained underemployment. Nevertheless, it attracts many young people. The number of students exceeds the available jobs by far. A potential explanation for this puzzle is that artistic work might result in exceptionally high job satisfaction, a conjecture that has been mentioned at various times in the literature. We conduct the first direct empirical investigation into artists’ job satisfaction. The analysis is based on panel data from the German Socio-Economic Panel Survey. Artists on average are found to be considerably more satisfied with their work than non-artists, a finding that corroborates the conjectures in the literature. Differences in income, working hours, and personality cannot account for the observed difference in job satisfaction. Partially, but not fully, the higher job satisfaction can be attributed to the higher self-employment rate among artists. Suggestive evidence is found that superior “procedural” characteristics of artistic work, such as increased variety and on-the-job learning, contribute to the difference in job satisfaction.     

Populist linguistic tone in recent U.S. presidential campaign discourse: a DICTION analysis

ABSTRACT

This study analyzed the tone of public campaign remarks of right- and left-wing populist (Donald Trump and Bernie Sanders, respectively) and right and left-wing non-populist (Mitt Romney and Hillary Clinton, respectively) U.S. presidential candidates using DICTION 7.0. Findings suggest that populists tended to use a linguistic tone that is high in pessimism, group abstractness, and exclusion. Pessimism and group abstractness were positively associated with immigration language in right-wing populist speech. Commonality and “we-ness” were positively associated with populist language in left-wing populist speech.
