梅花拳"文场与武场"考辨

通过民族史学、体育史学、体育理论等学科原理,结合文献资料、综合分析法等,对梅花拳“文场与武场”的体育文化内容、体育文化特征及两者辩证关系进行系统研究。结果显示:梅花拳由文场与武场组成,文场敬祖师,研究拳理,有文化典藉世代相传。它集佛、道、儒三家学说和周易之理为一体,修心养性,炼神炼气,称为文功。武场主要进行武功锻炼,传授拳理等。以“练形以合外,练气以实内,由外及内,再由内而达外,内外一体。精气神合一,自成金刚不坏之体”为练武目的,最后上升到文功。文场是该拳派的领导核心,文场领导武场,文场是武场的高级阶段。     

Acceleration patterns in the lower and upper trunk during running

Abstract

The purpose of the present study was to relate 3D acceleration patterns of the lower and upper trunk during running to running gait cycle, assess the validity of stride duration estimated from acceleration patterns, investigate speed-dependent changes in acceleration, and examine the test–retest reliability of these parameters. Thirteen healthy young men performed two running trials each on a treadmill and on land at three speeds (slow, preferred, and fast). The 3D accelerations were measured at the L3 spinous process (lower trunk) and the ensiform process (upper trunk) and synchronised with digital video data. The amplitude and root mean square of acceleration and stride duration were calculated and then analysed by three-way analysis of variance to test effects of running conditions, device location, and running speed. Bland-Altman analysis was used to evaluate the test–retest reliability. Marked changes in acceleration were observed in relation to foot strike during running. Stride durations calculated from the vertical accelerations were nearly equal to those estimated from video data. There were significant speed effects on all parameters, and the low test–retest reliability was confirmed in the anterior–posterior acceleration during treadmill running and the anterior–posterior acceleration at slow speed during treadmill and overground running.     

Busy doing nothing? Physical education teachers' perceptions of young people's participation in leisure-sport

Within the substantial body of research examining the professional knowledge of physical education (PE) teachers one particular area remains relatively under-explored: namely, their understandings of young people's participation in leisure-sport and the implications of this, if any, for the practice of PE. There are grounds for thinking, however, that in this aspect of their professional knowledge PE teachers might not be as conversant with patterns of participation—among young people, generally, and their own pupils, in particular—as one might expect. In order to examine this tentative hypothesis, the present study involved focus groups with a total of 29 PE teachers at six secondary schools in England. A central finding of the study was that PE teachers' perceptions of their youngsters' leisure-sport lives tended to be characterized by a blend of myth and reality. Many teachers, for example, underestimated the levels of participation in leisure-sport both of their own pupils and the 15–16 years age group, generally. Nevertheless, the teachers' observations regarding what amounted to growing and diversifying sporting repertoires among their pupils were, to a greater or lesser degree, commensurate with the profiles reported by the pupils, and with wider trends associated with the changing lifestyles and preferences of young people. The paper concludes by briefly locating this study of professional knowledge within the sociology of knowledge, while observing that the content and form of PE for Year 11 pupils at the six schools in this study appeared to be informed by the common-sense, everyday knowledge of PE teachers rather than by evidence from national or local surveys of young people or studies of their own pupils.     

Mature-age students-how are they different?

Mature-age students have formed a significant proportion of preservice students in primary teacher education over recent years. Academic staff have reported a difference between mature-age students and school-leavers, particularly in motivation and achievement. This report examines part of a study which explored mature-age students' views about aspects of teaching science and technology, compared to the views of students who came to university straight from school. It examines, in particular, students' personal feelings of adequacy in teaching science and technology in primary schools. Specialisations: primary teacher education, teaching strategies in science.     

Inequality – ‘wicked problems’, labour market outcomes and the search for silver bullets

In recent years concerns about inequality have been growing in prominence within UK policy debates. The many causes of inequality of earnings and income are complex in their interactions and their tendency to reinforce one another. This makes inequality an intractable or ‘wicked’ policy problem, particularly within a contemporary context in which many of the established policy responses from previous eras are at best discussed in muted terms and more normally deemed to be unavailable. This reflects the eclipse of ‘equality of outcome’ models and the concomitant rise of ‘equality of opportunity’ as the new policy mantra from Thatcher onwards. As traditional policy responses have withered, the role of education and training as a ‘silver bullet’ that can address a host of economic and social challenges has come to the fore. This article outlines policy makers’ beliefs that improving the educational attainment of students from lower socio-economic backgrounds can enable them to compete more effectively for elite jobs, and also that increasing the supply of educated employees can transform the level of demand for skills from employers. These beliefs are then critiqued, with reference to occupational congestion, over-qualification and the evidence that skills supply does not always create its own demand.     

The learner experience of Curriculum 2000: implications for the reform of 14–19 education in England

In September 2000, new qualifications for 16–19 year olds, known as Curriculum 2000, were introduced in England, Wales, and Northern Ireland with the aim of broadening the advanced level curriculum. It was left to schools, colleges, and their learners, however, to decide how these new qualifications would be used to build learner programmes of study. In this voluntarist context, the views and actions of learners have been an important factor in determining the course of the reforms. This article, which is based primarily on a study of 42 learners in a school/college consortium in the south west of England, provides a chronological account of learner experiences of these reforms during their first 2 years of implementation. The consortium discussed here offered a high‐volume study programme similar in size and content to those being proposed by the Tomlinson Working Group on 14–19 curriculum and qualifications reform in England. Learners found their expanded programmes onerous, due in part to the nature of the new qualifications and in part to the context of their implementation. The article concludes by identifying a number of policy lessons for 14–19 reform arising from this research.     

A step function in pigeons’ temporal generalization in the peak shift task

Pigeons were reinforced for pecking a key following one signal duration (S+) but not following another signal duration (S?). The S+ and S? were 2.52 and 5.67 sec, respectively, counterbalanced across birds. Subsequent generalization tests with a range of signal durations revealed a step function, with high response rates for all durations on the S+ side of the distribution, low response rates for all durations on the S? side, and an intermediate rate for the intermediate duration. A comparison group of pigeons trained with only the S+ duration showed a flat generalization function. For the discrimination-trained birds, the delay between signal termination and opportunity to respond was subsequently varied during generalization testing. A step function again appeared, and no evidence of subjective shortening over the delay was found. The overall pattern of results suggests that the birds categorized the temporal signal into two classes and retained a categorical code over the delay.     

Prosocial and antisocial behavior in sport: the role of coaching style, autonomous vs. controlled motivation, and moral disengagement

The purpose of this study was to examine whether the relationships between contextual factors (i.e., autonomy-supportive vs. controlling coaching style) and person factors (i.e., autonomous vs. controlled motivation) outlined in self-determination theory (SDT) were related to prosocial and antisocial behaviors in sport. We also investigated moral disengagement as a mediator of these relationships. Athletes' (n = 292, M = 19.53 years) responses largely supported our SDT-derived hypotheses. Results indicated that an autonomy-supportive coaching style was associated with prosocial behavior toward teammates; this relationship was mediated by autonomous motivation. Controlled motivation was associated with antisocial behavior toward teammates and antisocial behavior toward opponents, and these two relationships were mediated by moral disengagement. The results provide support for research investigating the effect of autonomy-supportive coaching interventions on athletes' prosocial and antisocial behavior.     

Young offenders in New South Wales,Australia and the need for remedial sexual health education

The 2005–2008 Australian National Sexually Transmissible Infections Strategy identifies young people as a key target group in need of sexual health education, screening and management. For young people who are in contact with the New South Wales (NSW) juvenile justice system, a dire need for remedial sexual health education exists. NSW young offenders indicate initiation of sexual activity at a younger age than their peers, higher numbers of sexual partners, infrequent condom use and higher rates of sexually transmitted infections. They also report family instability, poor accessing of health services, and low school attendance: all factors that result in poor sexual knowledge and health outcomes. An examination into the cognitive profile of these young offenders indicates remedial education for this group may require a dual approach in order to redress their specific circumstances and needs. The first approach should target young offenders who simply missed out on stages of sexual health information in the school curriculum. The second approach requires a tailored teaching methodology more appropriate for a group with atypical cognitive profiles. Both approaches need to engage an educative model that acknowledges that these disadvantaged young people are already sexual active; and that many did not have the benefit of an informed or consensual decision making processes. More importantly, the tailoring of a sexual health education program to these young people needs to resonate with teaching to a cognitively distinctive population who have experienced higher than usual rates of alcohol and other drugs abuse, and higher than usual episodes of physical and emotional abuse and neglect.
