Statistical methods for analysing discrete and categorical data recorded in performance analysis     

Nevill AM  Atkinson G  Hughes MD  Cooper SM 《Journal of sports sciences》2002,20(10):829-844

In this paper, we identify appropriate statistical methods for analysing categorical differences in discrete variables or 'performance indicators' resulting from performance analysis. The random mechanisms associated with discrete events do not follow a normal distribution; that is, the normal distribution is a continuous not a discrete probability distribution. We propose appropriate statistical methods based on two key discrete probability distributions, the Poisson and binomial distributions. Two approaches are proposed and compared using examples from notational analysis. The first approach is based on the classic chi-square test of significance (both the goodness-of-fit test and the test of independence). The second approach adopts a more contemporary method based on log-linear and logit models fitted using the statistical software GLIM. Provided relatively simple one-way and two-way comparisons in categorical data are required, both of these approaches result in very similar conclusions. However, as soon as more complex models or higher-order comparisons are required, the approach based on log-linear and logit models is shown to be more effective. Indeed, when investigating those factors and categorical differences associated with binomial or binary response variables, such as the proportion of winners when attempting decisive shots in squash or the proportion of goals scored from all shots in association football, logit models become the only realistic method available. By applying log-linear and logit models to discrete events resulting from notational analysis, greater insight into the underlying mechanisms associated with sport performance can be achieved.  相似文献

Not Quite Free? Irish Postcoloniality and the Career of Pat O'Callaghan     

Mike Cronin 《国际体育史杂志》2015,32(7):899-908

This paper explores the career of the Irish Olympian Pat O'Callaghan. He won successive hammer-throwing titles in the 1924 and 1928 Olympics as a representative of the independent Irish state. The paper argues that in these Olympics, O'Callaghan can be considered as representing a postcolonial state, in line with much scholarship on other aspects of Irish culture. However, the Irish later fell into a dispute with the International Amateur Athletics Federation and the International Olympic Committee, which were largely steered by the British in dealing with contentious issues over the Irish border, and the Irish were thus effectively banned from the 1936 games. The paper concludes with a discussion over the nature of postcolonial identities in sport, and the complexities around the issue in relation to the constant mediation over what national identities mean within the context of rule-making by international sporting bodies.  相似文献   

The Visual in Sport History: Approaches,Methodologies and Sources     

Mike Huggins 《国际体育史杂志》2015,32(15):1813-1830

Historians of sport now increasingly accept that visual inquiry offers another dimension to social and cultural research into sport and its history. It is complex and its boundaries are rapidly evolving. This overview offers a justification for placing more emphasis on visual approaches and an introduction to the study and interpretation of visual culture in relation to the history of sport. It stresses the importance of adopting a critical approach and the need to be reflective about that critique. An ever-widening range of visual data are now being explored; so, this paper begins with a brief survey of sources that potentially offer rich returns, from film and photographs to posters and paintings or standards and statues. It next provides a critical assessment at an introductory level of some of the more important methodologies now emerging to help interpret these. This can be no more than a personal choice, given their sheer variety and interdisciplinary nature, and the reality that many historians of sport adopt a mixture of methods and approaches. Approaches covered include content analysis, iconography and iconology, semiology, psychoanalysis, discourse analysis, and reception and audience studies. Examples of recent studies of visual studies are used to illustrate the discussion.  相似文献   

Interactive Kiosk at the Texas Tech University Libraries     

Ryan Litsey  Susan Hidalgo  Kaley Daniel  Julie Barnett  Amy Kim  Shannon Jones 《Journal Of Access Services》2015,12(1-2):31-41

The academic library, given its often privileged position on campus, is the information source that can include directional as well as general campus facts among the myriad of print and e-resources for reference. Also, an academic library's audiences can be quite varied and include prospective students or parents seeking more general knowledge of the building and the campus. Many times this need for information drives patrons to the library service desks. Sometimes, especially during the high-demand seasons of new student orientation and beginning of the fall semesters, the desk is so busy that many patrons will leave because they don't have the time to wait. To address this immediate need for information, Texas Tech University Libraries developed an interactive kiosk to provide general information for frequently asked questions in a more efficient, creative, and interactive way. The kiosk provides a fun method of satisfying a patron's information needs without the requirement of a staff member or the need to wait in line for help. The kiosk is available as long as the Library is open and provides a variety of useful answers to general questions, as well as facts about the Library.  相似文献   

INTERNAL FACTOR STRUCTURE AND CONVERGENT VALIDITY EVIDENCE: THE SELF‐REPORT VERSION OF SELF‐REGULATION STRATEGY INVENTORY     

Timothy J. Cleary  Leah Dembitzer  Ryan J. Kettler 《Psychology in the schools》2015,52(9):829-844

Using a sample of 348 middle school students, we gathered evidence regarding the internal consistency of scores, as well as the internal factor structure and convergent validity evidence for inferences from a self‐report questionnaire called the Self‐Regulation Strategy Inventory–Self Report. Confirmatory factor analysis revealed that the fit indexes for a hierarchical model (composite, three factors) and a single‐level, three‐factor model were highly similar but mixed. Respecification of the hierarchical model based on conceptual overlap of items led to substantial improvement in the overall fit of the model, as indicated by the root mean square error of approximation, chi‐square/df, and the comparative fit index. Correlational analyses also provided strong convergent validity evidence, as the three subscales exhibited statistically significant relations with four motivation beliefs (i.e., self‐efficacy, perceived instrumentality, task interest, perceived responsibility) and two distinct markers of regulation‐related behaviors (i.e., teacher ratings, office discipline referrals).  相似文献
