Umpire participation: is abuse really the issue?

Umpires (or referees) are essential for the ongoing production of organised sport. It has been widely argued that abuse of umpires by players, coaches, and spectators is ubiquitous and aversive, therefore engendering attrition. Cognitive behavioural theory specifies that attrition and continuation are best understood by identifying the ways that stimuli are interpreted. In this study, 22 umpires of professional and semi-professional Australian Rules football were interviewed to determine what they think of abusive behaviour, and what they find to be rewarding about umpiring. Findings showed that umpires routinely reframe abuse, considering it to be a normal part of their role. Abuse was not deemed to be particularly aversive, and there was no evidence that it contributes to attrition. On the other hand, umpires enjoyed the social world they share with other umpires, and identified social interactions among umpires as a key reason for continuing to umpire. This study highlights the important role that socialisation into the social world of umpiring plays in helping umpires to reframe abuse, and the importance of socialising with other umpires in maintaining their commitment to umpiring. It is suggested that the social rewards of umpiring should be stressed in umpire recruitment, and that the social world of umpiring should be incorporated into umpire training and retention.

Automatic labeling of sports video using umpire gesture recognition

We present results on an extension to our approach for automatic sports video annotation. Sports video is augmented with accelerometer data from wrist bands worn by umpires in the game. We solve the problem of automatic segmentation and robust gesture classification using a hierarchical hidden Markov model in conjunction with a filler model. The hierarchical model allows us to consider gestures at different levels of abstraction and the filler model allows us to handle extraneous umpire movements. Results are presented for labeling video for a game of Cricket.

Segmentation of intentional human gestures for sports video annotation

We present results on the recognition of intentional human gestures for video annotation and retrieval. We define a gesture as a particular, repeatable, human movement having a predefined meaning. An obvious application of the work is in sports video annotation where umpire gestures indicate specific events. Our approach is to augment video with data obtained from accelerometers worn as wrist bands by one or more officials. We present the recognition performance using a Hidden Markov Model approach for gesture modeling with both isolated gestures and gestures segmented from a stream.

Creating communities that lead to retention : the social worlds and communities of umpires

Umpires (referees) are essential for sport competition, yet many sports report difficulty in recruiting and retaining umpires. Therefore, this research sought to better understand what experiences will ensure continued participation in umpiring. Previous literature suggests that the communities created are vital to umpire retention. Thus, the aim of this research was to identify the factors that lead to, or detract from sense of community for umpires. Twenty-two Australian Rules football umpires were interviewed using a semi-structured approach. This study revealed that Lack of Administration Consideration, Inequity (specifically related to remuneration and resources), Competition, Common Interest (specifically in the sport, interactions within football community, and/or within social spaces) impacted the development of sense of community for umpires. This study demonstrates that as umpires move through their careers, the outcome of the noted factors to enhance or detract from sense of community change. Implications for umpire education, accreditation, and management aimed at retaining umpires are discussed.

Win at all costs or lose gracefully in high-stakes competition? Gender differences in professional tennis

This article examines line-call challenges by male and female professional tennis players in major tournaments around the world. In terms of utilization rates, we find that the genders behave similarly. Nevertheless, we do detect some intriguing gender differences in these challenges. First, male players’ challenges are more likely to be provoked by those of their opponents. More importantly, at tiebreaks, females are more likely to reverse an umpire’s unfavorable call, while males make relatively more unsuccessful challenges. Furthermore, we find that men are a lot more likely to make “embarrassing” line-call challenges at tiebreaks and offenses (i.e., when the shot lands at the opponent’s side of the tennis court) than women. These significant gender differences suggest that women particularly diverge from men at crucial junctures of the match such as tiebreaks. Differences in factors such as risk aversion, overconfidence, pride, shame, and strategic signalling behavior might help us to explain these gender-difference findings in line call challenges.

A generalization of correlated equilibrium: A new protocol

A new correlation scheme (leading to a special equilibrium called “soft” correlated equilibrium) is introduced for finite games. After randomization over the outcome space, players have the choice either to follow the recommendation of an umpire blindly or freely choose some other action except the one suggested. This scheme can lead to Pareto-better outcomes than the simple extension introduced by [Moulin, H., Vial, J.-P., 1978. Strategically zero-sum games: the class of games whose completely mixed equilibria cannot be improved upon. International Journal of Game Theory 7, 201–221]. The informational and interpretational aspects of soft correlated equilibria are also discussed in detail. The power of the generalization is illustrated in the prisoners’s dilemma and a congestion game.

Generalized correlated equilibrium for two-person games in extensive form with perfect information

A correlation scheme (leading to a special equilibrium called “soft” correlated equilibrium) is applied for two-person finite games in extensive form with perfect information. Randomization by an umpire takes place over the leaves of the game tree. At every decision point players have the choice either to follow the recommendation of the umpire blindly or freely choose any other action except the one suggested. This scheme can lead to Pareto-improved outcomes of other correlated equilibria. Computational issues of maximizing a linear function over the set of soft correlated equilibria are considered and a linear-time algorithm in terms of the number of edges in the game tree is given for a special procedure called “subgame perfect optimization”.

Narratives of a race: how the media judged a presidential debate

The first debate in 2008 was a turning point in the presidential electioncampaign: a race that was close before the debate turned decisively inObama’s favor following it. This article explores how the media reachedtheir verdict that “Obama won.” We examine two aspects of this problem:how, in practice, the media reached this verdict and whether they madethe right decision from a normative standpoint. Based on content analysisof debate transcripts, we argue that the media interpreted the debate bysynthesizing three pre-debate narratives in roughly equal proportions.Crucially, two of these narratives favored Obama. We also find that the“Obama won” verdict was consistent with what we might expect had thedebate been judged by a public-spirited umpire.
