Comment on “Talent identification and promotion programmes of Olympic athletes”

Abstract

Waist girth is recognised as a better predictor of obesity, particularly abdominal obesity, compared to other measures. Although several protocols for waist girth exist, arm position is either ignored, or not specified in unambiguous terms. Therefore, the purpose of this study was to determine if arm position influenced anthropometric waist girth measurement. Waist girth was measured in 92 adults (19 males, 73 females) with arms relaxed, abducted, horizontal, folded across the chest (three variations) and raised vertically. Duplicate measures, in all positions, were recorded by a single International Society for the Advancement of Kinanthropometry (ISAK)-trained technician to a precision of 0.2% technical error of measurement (TEM). Arm position had a significant effect (P < 0.001) on waist girth. Male participants had greater waist girth than females (P < 0.001) and the waist girth differences across the varying arm positions exhibited a significant position-by-gender interaction (P < 0.001). The arm position-by-body mass index (BMI) category interaction was also significant (P = 0.016) with greater differences observed at higher BMI. These findings suggest caution in comparing results of different studies where arm position is not specified and indicate that the arm position corresponding to the ISAK protocol has the lowest error and is therefore recommended.     

Talent development: linking the stakeholders to the process

Abstract

The three stakeholders (coaches, parents and the National Governing Body) in Talent Identification and Development (TID) are important factors in athlete development. How each of them perceive the key constructs of Talent Identification and Development (i.e. sport specialisation and selection, practice, athlete development, junior and adult success, and the role of the stakeholders), and the coherence of that understanding is not well understood. This study focuses on junior performance tennis and investigates the perceptions of coaches, parents and sports organisations (a National Governing Body) of the five key constructs of Talent Identification and Development. We were interested in examining (a) the extent to which stakeholder perceptions relate to research, (b) the coherence of each stakeholder's perceptions and (c) the extent to which there is coherence between what stakeholders understand each other thinks. Seventy-five coaches, parents, and National Governing Body staff completed a questionnaire that asked participants to rate their degree of agreement/disagreement with researched ‘principles' of Talent Identification and Development. The results suggest that stakeholders do not strongly agree with the research supporting principles of Talent Identification and Development. Furthermore, a significant lack of coherence of stakeholder perceptions was evident. This lack of coherence was also evident in each group's understanding of what the other stakeholders believed. The impact of these results on the Talent Identification and Development process is discussed.     

Initial identification & selection bias versus the eventual confirmation of talent: evidence for the benefits of a rocky road?

Abstract

The relative age effect (RAE), whereby earlier birthdate children within a selection year are more commonly selected as talented, has been highlighted in the literature. As a consequence, these young athletes get into specialised training earlier and in greater numbers, leading (it is suggested) to a disproportionate opportunity for success. However, this disproportionality seems not to be manifest in senior teams. Accordingly, we examine the identification and conversion rates for academy rugby players, examining a sample of all players passing into and either graduating, or being dismissed from, a major English rugby academy. Data demonstrated a reversal of the RAE “benefit”, whereby late-birth players were less likely to be selected, but more likely to achieve senior professional status. Possible reasons are explored and, on the basis of our data, we propose a psychologically based explanation of greater “growth” due to additional challenge experienced by these initially disadvantaged younger players.     

‘I was dead restorative today’: from restorative justice to restorative approaches in school

This paper explores definitions and understandings of restorative practices in education. It offers a critique of current theoretical models of restorative justice originally derived from the criminal justice system and now becoming popular in educational settings. It questions the appropriateness of these concepts as they are being introduced to schools in parts of the UK and refers to a recent Scottish Executive funded pilot initiative to implement restorative practices in schools. The paper then reflects on some findings from the evaluation of this pilot project, outlines a new notion of restorative approaches and suggests that this broader conceptualisation may offer an important way in which to promote social justice in education and to reassess the importance and inevitability of conflicting social interaction and structures inherent in schools as complex social institutions.     

Biological Inquiry: A New Course and Assessment Plan in Response to the Call to Transform Undergraduate Biology

We transformed our first-year curriculum in biology with a new course, Biological Inquiry, in which >50% of all incoming, first-year students enroll. The course replaced a traditional, content-driven course that relied on outdated approaches to teaching and learning. We diversified pedagogical practices by adopting guided inquiry in class and in labs, which are devoted to building authentic research skills through open-ended experiments. Students develop core biological knowledge, from the ecosystem to molecular level, and core skills through regular practice in hypothesis testing, reading primary literature, analyzing data, interpreting results, writing in disciplinary style, and working in teams. Assignments and exams require higher-order cognitive processes, and students build new knowledge and skills through investigation of real-world problems (e.g., malaria), which engages students’ interest. Evidence from direct and indirect assessment has guided continuous course revision and has revealed that compared with the course it replaced, Biological Inquiry produces significant learning gains in all targeted areas. It also retains 94% of students (both BA and BS track) compared with 79% in the majors-only course it replaced. The project has had broad impact across the entire college and reflects the input of numerous constituencies and close collaboration among biology professors and students.     

The coming crisis of cultural engagement? Measurement,methods, and the nuances of niche activities

ABSTRACT

Do ticketing data and national survey data on attendance tell the same story? This question is particularly important in the context of debates over the power of new forms of data to supplant the “traditional” survey methods that have underpinned our understanding of the social stratification of culture. This paper compares three data sources on attendance: the Active Lives Survey, the Taking Part Survey, and Audience Finder. We first compare self-reported attendance at events in each English local authority from the Active Lives survey with ticket sales data, finding a close relationship. We follow up by comparing the distributions of ticket buyers across the Indices of Multiple Deprivation with those from Taking Part, finding that for widely-ticketed and widely-attended art forms they track closely together, providing support for existing trends. Ticketing data does not seem to offer more information on social stratification than traditional social science sources. However, we extend the comparison through more detailed analysis of subcategories within less well-researched forms – literature and dance events – where numbers of attendees are lower, with accompanying uncertainty in survey sources. We find that the audiences for dance vary widely, with ballet attendance being heavily socially stratified but attendance at contemporary dance much more similar to the general population. However, we find that audiences for literature events are more heavily socially stratified than almost any other art form, almost regardless of the subcategory. The power of new datasets is in offering specificity about artforms, rather than overturning what we know about culture and inequality.
