Charting the development of sport expertise: challenges and opportunities

This review poses three key issues that will progress our understanding of the sport expertise literature and its translational scientific impact. Primarily relying on research conducted in interceptive sport tasks, and to a lesser extent team sports, we review the perceptual-cognitive skills of sports experts and explore the challenge of designing a sufficiently representative task to examine expertise. We focus on the methodological challenges presented by the reciprocal relationship between players’ action capabilities and their perceptual-cognitive skill. Second, we consider the need for a paradigm shift in the experimental approach used when examining the development of sport expertise. In short, a shift from traditional expert-novice designs to more prospective longitudinal designs that cross-sectionally track the development of expertise is discussed. The final issue considers how the volume of in situ data now collected provides a rich source of information that sport expertise researchers have only begun to consider and integrate with more traditional sport psychology research. We demonstrate how statistical approaches that have described the likely trajectories of expert performers on their journey toward expertise coupled with more traditional qualitative experimental approaches can provide useful insights into the development of psychological performance skills and more broadly sport expertise.     

Inclusive dyslexia-friendly collaborative online learning environment: Malaysia case study

Currently available web page accessibility guidelines focus more on reading and writing, with inadequate attention to other aspects of online learning such as computer-mediated communication. This study aims to explore the engagement of Malaysia secondary school students with dyslexia and students without dyslexia on various synchronous and asynchronous communication interaction technologies in an online collaborative learning environment. Multiple case within subject qualitative study was employed to investigate the engagement of students using a semi structured interview guideline. The findings revealed that (1) text chat is unsuitable for learning discussion for all learners, (2) forum affords self-paced and organized formal discussion for most learners and (3) video conferencing is suitable for interactive face-to-face, verbal discussion for most learners.     

How schools train principals to use new teacher evaluation systems: A comparative case study of charter school and traditional public school principals

Over the past decade U.S. policymakers, practitioners, and researchers have sought to examine if changing teacher evaluation policies and systems have resulted in changes in identifying quality teachers and/or increased student achievement. This research generally shows most states have experienced little change in how teachers are rated. Researchers are now exploring why, in many cases, teacher evaluation reforms have failed to produce the desired systematic changes of better identifying quality teachers and better distinguishing teacher performance. Embedded within this line of inquiry is how principals (and other evaluators) are trained to use new teacher evaluation systems. This comparative case study observed six principals (three charter school principals and three traditional public school principals) in the U.S. state of Michigan as they learned and enacted a new teacher evaluation system. Additionally, all principals were interviewed three times throughout the school year, in an effort to examine how their initial teacher evaluation training impacted their evaluation of teachers. The research questions that guided this work were: (1) how are principals initially trained when their school adopts a new teacher evaluation system?; (2) in what ways does the training received by charter school principals compare to that of traditional public school principals?; and (3) how does initial training impact how principals evaluate teachers? Results indicate principals are trained to navigate the logistics of new teacher evaluation systems, but are not trained to evaluate teacher performance. Implications for policy and practice are discussed.     

The “Hand of God”'s: Essays in the Philosophy of Sport By Claudio M. Tamburrini. Published 2000 by Acta Universitatis Gothoburgensis,Box 222, SE-405 30, Sweden (167 pp.)

This paper contains a consideration of the notion of genius and its significance to the discussion of the aesthetics of sport. We argue that genius can make a positive aesthetic contribution in both art and sport, just as some have argued that the moral content of a work of art can affect its aesthetic value. A genius is an exceptional innovator of successful strategies, where such originality adds aesthetic value. We argue that an original painting can have greater aesthetic value than an exact replica, merely because it is the original. By parity of reasoning, a successful innovation in sport has additional aesthetic value just because it is a new creation. The genius is one who can provide this extra aesthetic pleasure and on that basis is rightly valued. The genius need not be conscious of how they achieve such innovations and thus find their own genius to be something they cannot explain but only demonstrate. In sport, innovations that offer new ways of playing or solving problems can produce competitive success which demands instant recognition and rewards.     

The importance of the International Tennis Federation's junior boys' circuit in the development of professional tennis players

Abstract

The relationship between junior boys' tennis success, as measured by a top 20 International Tennis Federation's Junior Circuit (ITFJC) ranking, and subsequent ranking accomplishments in professional men's tennis is discussed. The names, countries, and birthdates of all players to achieve a top 20 ITFJC boys' year-end ranking from 1992 to 1998 were recorded. The progress of these players through the professional ranks was then tracked to the end of 2004. Results indicate that 91% of top 20-ranked boys achieved a professional men's ranking, while a stepwise regression analysis revealed junior ranking (JR) to be a predictor of future, professional ranking (β = 0.232, r ² = 0.054, p < 0.05). A regression equation [predicted professional rank = 78.17 + 6.31?(JR)] accounted for a significant amount of variance in professional ranking. For male players, therefore, the achievement of a top 20 junior ranking appears to be a reasonable yardstick for future, professional success. The type of surface upon which junior players develop their games was also shown to influence professional ranking highs, with play on clay courts or a combination of clay and hard courts helping to produce higher, professionally ranked players than hard court play alone (p≤ 0.01).     

Rankings in professional men’s tennis: a rich but underutilized source of information

Abstract

Success in professional tennis is measured, at least in part, by rankings. However, there is little quantitative evidence to inform stakeholders regarding what represents the typical ranking progress of top-ranked players. The objective of this study was therefore to compare the ranking trajectories of male players whom achieved peak professional rankings in the Top 250, 175, 100, 50, 20 and 10. The 11,396 birthdates and weekly professional rankings of all players between 27 August 1973 and 31 October 2011 were collated. The peak ranks for each athlete according to their both chronological age and number of years on tour were identified and athletes were categorised into one of six career–peak ranking bands. One-way analysis of variance tests confirmed distinctive ranking trajectories, which were most pronounced among Top 10 players. The rankings of these players were statistically distinguishable following players’ second year on tour or by 17 years of age. The ranking signature of all Top 100 players emerged as significantly different to players that failed to enter the Top 100 by their fourth year on the tour. Indeed, the representation of ranking as a function of years on tour should be considered for use by tennis policy-makers in the future.     

Engaging suppliers in CRM: The role of justice in buyer–supplier relationships

Given the crucial role of suppliers in collaborative supply chains, it is surprising that little attention has been paid to the nature and management of supplier relationships in the implementation of a retailer's Customer Relationship Management (CRM) strategy. To address this gap in the extant literature, the theory of organizational justice is used to explore the extent to which perceived fairness in buyer–supplier relationships supports or inhibits supplier engagement with the CRM process. The rationale is that suppliers who feel fairly treated by key retail customers are more likely to invest resources in the acquisition and use of data central to the retailer's CRM strategy. By empirically testing a conceptual model linking downstream CRM to upstream SRM, the results provide evidence to indicate that customer data use is significantly influenced by perceptions of fairness, particularly with respect to the distribution of rewards, and the transparency of decision-making processes. As a key criticism of CRM centers upon the failure of organizations to exploit the full potential of customer data, the results highlight the usefulness of understanding the relational linkages between buyers and suppliers and the consequential behavior of suppliers in terms of engagement with customer data vital to the success of retailers’ CRM strategies.     

Tennis

The study investigated differences in the one‐ (SH) and two‐handed (DH) backhands when hit flat, across‐court (AC) and down‐the‐line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college‐level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high‐speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1°; DH: 83.4°) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m; DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m; DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s; DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique.     

A Two-Year Longitudinal Study of Stressful Life Events, Social Support, and Social Problem-Solving Skills: Contributions to Children''s Behavioral and Academic Adjustment

We investigated the contributions of stressful life events and resources (social support and social problem-solving skills) to predicting changes in children's adjustment. At Time 1, 361 third through fifth graders completed measures of social support and social problem-solving skills. Their parents completed a stressful life events scale and a child behavior rating measure. The children's teachers provided ratings of behavioral and academic adjustment. 2-year follow-up data (Time 2) were obtained for approximately half of the sample on the same measures. Time 1 stressful life events and resources showed some significant but modest zero-order correlations with the Time 2 adjustment indices. Hierarchical multiple regressions revealed prospective effects for Time 1 social support on later teacher-rated competencies and grade-point average. In addition, increases over time in social support and social problem-solving skills (a composite score) were significantly related to improvement in behavioral and academic adjustment, whereas stressful life events were not predictive of adjustment.
