Reliability and validity of a talent identification test battery for seated and standing Paralympic throws

Paralympic throwing events for athletes with physical impairments comprise seated and standing javelin, shot put, discus and seated club throwing. Identification of talented throwers would enable prediction of future success and promote participation; however, a valid and reliable talent identification battery for Paralympic throwing has not been reported. This study evaluates the reliability and validity of a talent identification battery for Paralympic throws. Participants were non-disabled so that impairment would not confound analyses, and results would provide an indication of normative performance. Twenty-eight non-disabled participants (13 M; 15 F) aged 23.6 years (±5.44) performed five kinematically distinct criterion throws (three seated, two standing) and nine talent identification tests (three anthropometric, six motor); 23 were tested a second time to evaluate test–retest reliability. Talent identification test–retest reliability was evaluated using Intra-class Correlation Coefficient (ICC) and Bland–Altman plots (Limits of Agreement). Spearman’s correlation assessed strength of association between criterion throws and talent identification tests. Reliability was generally acceptable (mean ICC = 0.89), but two seated talent identification tests require more extensive familiarisation. Correlation strength (mean r_s = 0.76) indicated that the talent identification tests can be used to validly identify individuals with competitively advantageous attributes for each of the five kinematically distinct throwing activities. Results facilitate further research in this understudied area.     

Increasing plantarflexion angle during landing reduces vertical ground reaction forces,loading rates and the hip’s contribution to support moment within participants

The ankle joint’s role in shock absorption during landing has been researched in many studies, which have found that landing with higher amounts of plantarflexion (PF) results in lower peak vertical ground reaction forces and loading rates. However, there has not yet been a study that compares drop landings within participants along a quantitative continuum of PF angles. Using a custom-written real-time feedback program, participants adjusted their ankles to an instructed PF angle and dropped onto two force platforms. For increasing PF, peak ground reaction force and peak loading rate during weight acceptance decreased significantly. The hip’s contribution to peak support moment decreased as PF at initial contact increased up to 30°. The ankle and knee contributions increased over this same continuum of PF angles. There appears to be no optimal PF angle based on peak ground reaction force and loading rate measurements, but there may be an optimum where joint contributions to peak support moment converge and the hip moment’s contribution is minimised.     

Talent,Schmalent: An Instructional Design/Action Research Framework for the Professionalization of Teaching in Academic Libraries

When myths become canonical beliefs within a professional culture, they can have a profound impact on professional practice. In this paper we identify as a pernicious educational myth the belief that the ability to teach well is a naturally occurring innate talent or skill. The first two sections of the paper aim to demonstrate (i) that the concept of the naturally gifted teacher is a myth based on factually incorrect assumptions about expertise development and (ii) that this myth has several major negative implications for professional practices around teaching in academic libraries. We then we draw on the education literature to offer an alternative model for the cultivation of teaching excellence, an instructional design/action research framework that prioritizes ‘deliberative’ practice over innate talent. We close with suggestions for how academic librarians and library administrators can implement this framework within their institutions.     

教育是否能够改变社会――专访美国威斯康辛大学麦迪逊校区课程与教学系Michael W.Apple教授

李晓军:在美国,有相当部分人认为,美国的基础教育之所以落后,是因为缺乏"共同文化"基础上的统一课程标准,然而当前美国推行的以"标准化测试"为特征的教育改革,也受到反对者的批评。"标准化测试"的利弊得失在美国国内成为争论的焦点。那么在您看来,当前美国正在实施的国家课程与标准化测验政策,社会的反响如何?教育的成功与否真的能通过标准化测试进行测量吗?     

A contested profession: employability,performativity and professionalism in Irish further education

Further education typically represents the vocational, technical and practice-based forms of education, but this is now being repositioned in a neo-liberal era that is driving a performance-based and market-orientated vision of education in the Republic of Ireland and elsewhere. The implacable drive of neo-liberal economics in everyday practice is evident in the current economic and training discourses of further education, which aim to upgrade the employability of low-skilled and marginalised sectors of the population. The article provides an overview of shifts in educational policy and practices that align Irish further education with what has occurred in the UK and elsewhere through processes of professionalisation and performativity. Analysis of the potential impact on notions of professional identity in the sector helps to articulate the principles, pedagogies and philosophies that will be vital when contesting the performance cultures of New Managerialism that seem likely to ensue. We explore the implications in terms of the policy discourses, organisational structure and professional practices of further education. We contend that changes in these areas have profound impacts on the learning and knowledge base of further education, constraining its social justice and transformative capacity for the learners at the heart of further education.     

Child and Adolescent Predictors of Personality in Early Adulthood

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.
