Roster-Based Optimisation for Limited Overs Cricket

The objective of this research was to develop a roster-based optimisation system for limited overs cricket by deriving a meaningful, overall team rating using a combination of individual ratings from a playing eleven. The research hypothesis was that an adaptive rating system accounting for individual player abilities, outperforms systems that only consider macro variables such as home advantage, opposition strength and past team performances. The assessment of performance is observed through the prediction accuracy of future match outcomes. The expectation is that in elite sport, better teams are expected to win more often. To test the hypothesis, an adaptive rating system was developed. This framework was a combination of an optimisation system and an individual rating system. The adaptive rating system was selected due to its ability to update player and team ratings based on past performances. A Binary Integer Programming model was the optimisation method of choice, while a modified product weighted measure (PWM) with an embedded exponentially weighted moving average (EWMA) functionality was the adopted individual rating system. The weights for this system were created using a combination of a Random Forest and Analytical Hierarchical Process. The model constraints were objectively obtained by identifying the player’s role and performance outcomes a limited over cricket team must obtain in order to increase their chances of winning. Utilising a random forest technique, it was found that players with strong scoring consistency, scoring efficiency, runs restricting abilities and wicket-taking efficiency are preferred for limited over cricket due to the positive impact those performance metrics have on a team’s chance of winning. To define pertinent individual player ratings, performance metrics that significantly affect match outcomes were identified. Random Forests proved to be an effective means of optimal variable selection. The important performance metrics were derived in terms of contribution to winning, and were input into the modified PWM and EWMA method to generate a player rating. The underlying framework of this system was validated by demonstrating an increase in the accuracy of predicted match outcomes compared to other established rating methods for cricket teams. Applying the Bradley-Terry method to the team ratings, generated through the adaptive system, we calculated the probability of teami beating teamj. The adaptive rating system was applied to the Caribbean Premier League 2015 and the Cricket World Cup 2015, and the systems predictive accuracy was benchmarked against the New Zealand T.A.B (Totalisator Agency Board) and the CricHQ algorithm. The results revealed that the developed rating system outperformed the T.A.B by 9% and the commercial algorithm by 6% for the Cricket World Cup (2015), respectively, and outperformed the T.A.B and CricHQ algorithm by 25% and 12%, for the Caribbean Premier League (2015), respectively. These results demonstrate that cricket team ratings based on the aggregation of individual player ratings are superior to ratings based on summaries of team performances and match outcomes; validating the research hypothesis. The insights derived from this research also inform interested parties of the key attributes to win limited over cricket matches and can be used for team selection

A Statistical Investigation into Factors Affecting Results of One Day International Cricket Matches

The effect of playing “home” or “away” and many other factors, such as batting first or second, winning or losing the toss, have been hypothesised as influencing the outcome of major cricket matches. Anecdotally, it has often been noted that Subcontinental sides (India, Pakistan, Sri Lanka and Bangladesh) tend to perform much better on the Subcontinent than away from it, whilst England do better in Australia during cooler, damper Australian Summers than during hotter, drier ones. In this paper, focusing on results of men’s One Day International (ODI) matches involving England, we investigate the extent to which a number of factors – including playing home or away (or the continent of the venue), batting or fielding first, winning or losing the toss, the weather conditions during the game, the condition of the pitch, and the strength of each team’s top batting and bowling resources – influence the outcome of matches. By employing a variety of Statistical techniques, we find that the continent of the venue does appear to be a major factor affecting the result, but winning the toss does not. We then use the factors identified as significant in an attempt to build a Binary Logistic Regression Model that will estimate the probability of England winning at various stages of a game. Finally, we use this model to predict the results of some England ODI games not used in training the model

An embodied approach to disability sport: the lived experience of visually impaired cricket players

This thesis investigates the England Visually Impaired Cricket Team, whose squad members comprise sixteen men aged 18-54, and their lived experiences' of playing visually impaired cricket. This is the first piece of research to examine elite visually impaired cricket and the first to explicitly analyse the social dynamics of any visually impaired sports team. Through an embodied theoretical approach, that accounts for the corporeal experience of impairment alongside the role of social institutions and discourse in the high performance culture of modern disability sport, this thesis establishes the significant aspects of this previously unexamined research 'site', both on and off the pitch. This study consisted of ten months of ethnographic fieldwork using participant observation and semi-structured interviews shaped by a new method of recording and eliciting data. To capture the participants' sensorial experiences of playing visually impaired cricket, 'soundscape elicitation', the process of composing auditory 'tracks' of the players' participation and then using these recordings during semi-structured interviews to prompt sensorial discussions, was utilised. This original and innovative method was central to the production of previously unexamined knowledge and is a significant methodological advancement in the wider field of sensory studies. The findings present a number of original contributions to knowledge regarding 'sporting bodies', the sensorial experiences of sport, and the construction of identity through disability sport. The participants' embodied experiences of playing visually impaired cricket reveal an alternative way of 'being' in sport and physical activity. However, it is the inescapable ocularcentric value of 'sight' that inhibits the resistive potential of the game. Instead of the presumed empowering experience, elite visually impaired cricket is disempowering for many participants due to the irreversible relationship of blind cricket institutions with mainstream cricketing bodies. Furthermore, a 'hierarchy of sight' based upon the official sight classification process emerges that highly values those players with the highest sight classifications and marginalises the blind players. All of these factors inform visually impaired cricket players’ construction of their own identities. Although many players view visually impaired cricket as a way of demonstrating their 'normality', it actually accentuates the impairment that they are attempting to dissociate from and is one of the few social situations where they are 'outed' as disabled or blind

Globalizing Cricket

This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com. Globalizing Cricket examines the global role of the sport - how it developed and spread around the world. The book explores the origins of cricket in the eighteenth century, its establishment as England's national game in the nineteenth, the successful (Caribbean) and unsuccessful (American) diffusion of cricket as part of the development of the British Empire and its role in structuring contemporary identities amongst and between the English, the British and postcolonial communities. Whilst empirically focused on the sport itself, the book addresses broader issues such as social development, imperialism, race, diaspora and national identities. Tracing the beginnings of cricket as a 'folk game' through to the present, it draws together these different strands to examine the meaning and social significance of the modern game. This book is a must-read for anyone interested in the role of sport in both colonial and post-colonial periods; the history and peculiarities of English national identity; or simply intrigued by the game and its history

False Start: Quantitative representation of sportswomen in The Sydney Morning Herald in 2005, 2007 and 2011

Despite the increasing participation and success of women in sport in Australia, sportswomen continue to receive a significantly lower quantity of media coverage than sportsmen. This thesis will examine the impact of the 2006 Senate inquiry ‘About time! Women in sport and recreation in Australia’ and the 2010 Australian Sports Commission (ASC) report ‘Towards a Level Playing Field: sport and gender in Australian media’, which were designed to address the underrepresentation of sportswomen in the media. Content analysis of The Sydney Morning Herald 1 sports section was conducted to quantify the representation of sportswomen in 2005, prior to the inquiry, and in 2007 and 2011, following the publication of the inquiry and report. This thesis highlights that, despite the issue being deemed important enough to warrant a parliamentary inquiry and large-scale government-backed research, the quantitative coverage of sportswomen in SMH has not improved. Interviews with SMH sports journalists and an editor, combined with academic scholarship, offer insights into why underrepresentation of sportswomen in SMH still exists

Philosophical Issues in Sport Science

The role and value of science within sport increases with ever greater professionalization and commercialization. Scientific and technological innovations are devised to increase performance, ensure greater accuracy of measurement and officiating, reduce risks of harm, enhance spectatorship, and raise revenues. However, such innovations inevitably come up against epistemological and metaphysical problems related to the nature of sport and physical competition. This Special Issue identifies and explores key and contemporary philosophical issues in relation to the science of sport and exercise. It is divided into three sections: 1. Scientific evidence, causation, and sport; 2. Science technology and sport officiating; and 3. Scientific influences on the construction of sport. It brings together scholars working on philosophical problems in sport to examine issues related to the values and assumptions behind sport and exercise science and key problems resulting from these and to provide recommendations for improving its practice

Towards An Understanding of Talent Identification in Elite Sport

The purpose of this thesis was to examine the efficacy of talent identification (TID) programs in predicting future success in elite-level sport. A systematic literature review was performed in phase 1 to synthesize the existing studies. Findings from this review highlighted a high degree of homogeneity in the samples and inconclusive outcomes for the variables examined. The objective of phase 2 was to discern whether testing variables employed by Golf Canada (GC) were effective in discriminating skilled from less-skill athletes. Findings revealed that their TID model does not hold discriminative or predictive utility. This thesis contributes to a limited literature base and provides direction for future research to enhance the selection process for elite-level athletes
