Visual perception of action categories and the "bowl-throw" decision in cricket.

Cricket umpires, cricket bowlers, and physical education students (who were knowledgeable about the rules of cricket), were shown 72 videotaped point-light displays of cricket deliveries with varying extents of elbow flexion such that they ranged from highly “bowl-like” to highly “throw-like”. The observers made a bowl-throw decision about each display, and the umpires and bowlers reported their confidence on a 5-point scale. The percentage of displays reported as a “bowl” was 59, 40, and 44 for the umpires, bowlers, and students respectively. Umpires made significantly more bowl decisions than both the bowlers and students, but there was no difference between the latter groups. Umpires were significantly more confident than the bowlers in both their bowl and throw decisions. Thus, in an experimental setting, with no apparent costs or benefits associated with their decision-makin, umpires “called” a bowler significantly less frequently for throwing than other knowledgeable observers. The procedures devised for this experiment demonstrate that psychophysical methods can be applied to the problem of discrete action-category nominations in sport (e.g., bowl or throw, walk or run).

Whither sporting heritage : reflections on debates in Victoria about Waverley Park and the Melbourne Cricket Ground

The successful nomination of Waverley Park to the Victorian Historic Register
proved as controversial as the stadium was during its thirty-year existence. The
nomination was accepted primarily on the grounds of the social historical value of the site, rather than its architectural or engineering qualities, but in fact a range of different social histories were in conflict during the registration process. Four of the social histories involved are outlined and their influence on the outcome assessed. Some of the implications for the evaluation of sporting heritage sites emerge therefrom (Hay, R., Lazenby, C., Lewis, N., Haig-Muir, M., Mewett, P., 2001).

Occupying the crease: an exploration of youth cricket in New Zealand

Recruiting and retaining participants is a challenge that most sport administrators face. The present study examined motives for participation/discontinuation in cricket, propensity to play in the future, and the influence that various initiatives had on youths' propensities to play. A nationwide survey of 858 young New Zealand cricketers revealed six underlying motives for participating in cricket: team, competition, mastery, extrinsic rewards, fitness and being active, with the first three of these being the strongest predictors of propensity to play. Together the six motives explained 17% of the variance in propensity to play. None of the initiatives tested increased the likelihood of playing cricket for those who were currently involved. For those who had stopped playing, their reasons for ceasing were most likely to be the lure of other sports or activities. Nonetheless, initiatives that increased their chances of participating in cricket again were playing in a social competition, having better equipment, having less costly equipment, and being provided with the opportunity to meet top players. These findings have important implications for cricket administrators in terms of the management and promotion of youth cricket in New Zealand.

On the automatic indexing of cricket using camera motion parameters

This paper describes an application of camera motion estimation to index cricket games. The shots are labeled with the type of shot: glance left, glance right, left drive, right drive, left cut, right pull and straight drive. The method has the advantages that it is fast and avoids complex image segmentation. The classification of the cricket shots is done using an incremental learning algorithm. We tested the method on over 600 shots and the results show that the system has a classification accuracy of 74%.

Classifying and learning cricket shots using camera motion

This paper presents a method to classify and learn cricket shots. The procedure begins by extracting the camera motion parameters from the shots. Then the camera parameter values are converted to symbolic form and combined to generate a symbolic description that defines the trajectory of the cricket bell. The description generated is used to classify the cricket shot and to dynamically expand or update the system's knowledge of shots. The first novel aspect of this approach is that by using the camera motion parameters, a complex and difficult process of low level image segmenting of either the batsman or the cricket ball from video images is avoided. Also the method does not require high resolution images. Another novel aspect of this work is the use of a new incremental learning algorithm that enables the system to improve and update its knowledge base. Unlike previously developed algorithms which store training instances and have simple method to prime their concept hierarchies, the incremental learning algorithm used in this work generates compact concept hierarchies and uses evidence based forgetting. The results show that the system performs well in the task of classifying four types of cricket shots.

Challenges in the development of standards for synthetic turf for Australian football and cricket

Given the escalating drought conditions in Australia, synthetic surfaces have recently been explored as a viable surface option for community-level Australian football–cricket ovals. The vast majority of Australian football ovals are transformed into cricket pitches during the football off-season and hence the characteristics of both sports had to be duly considered in the development of standards that could be tested in a laboratory setting, for a synthetic turf surface. This paper describes the data collection and test methods undertaken in the development of the standards for synthetic surface use in Australian football and cricket. The paper also discusses the issues and challenges encountered during the development of standards for multi-sport synthetic surfaces to ensure player safety while maintaining the performance characteristics of both sports. Surface property and ball interaction tests were undertaken on natural playing surfaces, both in situ and in the laboratory to determine the properties of the current playing surface for each sport. This paper highlights the importance of careful consideration of the characteristics of both games and the use of equipment from both sports in the testing methods. The standards described in this paper have now been accepted by the Australian Football League and Cricket Australia and the product approval process and use of synthetic surfaces for Australian football and cricket is imminent.

Short-term impacts of the cricket match performances on national share markets – a case study of India and Australia

We investigate the impact that investor sentiment can have on stock market following performances by the national cricket teams of India and Australia in one-day cricket matches from 1990 to 2011. Motivated by previous findings of cricket’s impacts on stock markets, this study expands on previous research by investigating whether performances of individuals within the teams can also have an impact on their respective leading stock indices. Using an event study, we find no evidence of player or team performances significantly impacting the stock or futures markets. However, we find evidence of a ‘mood effect’ of poor performance by key players of national cricket teams in terms of significant drop in trading volumes in the following day. Our research poses and statistically examines some interesting questions and opens up the field for further research on this intriguing topic of sporting event impacts on national economies.

Advertising the 2015 Cricket World Cup: representing multicultural female sports fans

Intersectional accounts of how women sports fans from diverse cultural backgrounds are represented remain largely unconsidered in fandom literature. This article examines an Australian advertisement for the 2015 Cricket World Cup, which features as its main protagonists female cricket fans supporting a variety of countries. It makes use of a transnational feminist cultural studies paradigm to frame a discussion of how commercial sports media narratives situate these fans as ‘‘ordinary.’’ In considering how the multicultural female sports fan is configured as ordinary in the Australian sporting context, I demonstrate the ways In which narratives of gender and nation are mobilized to situate multicultural women as marginal to both the Australian nation and cricket, despite the prominence given to ethnically diverse women in the advertisement. This manoeuvre, I argue, responds to the cultural and economic transformations of cricket globally, simultaneously denying and universalizing difference as a mechanism to assuage the anxieties generated by the decentering of Western power in international cricket.

Automatic summarization of broadcast cricket videos

Summarization of cricket videos is very important because of three reasons: 1) its long duration making manual highlights generation tedious 2) less explored area compared to other sports like soccer 3) huge viewership. We propose a novel summarization scheme for cricket which exploits its contextual semantics. First, we detect the bowling frames based on which the video is temporally segmented into individual deliveries. Then each temporal segment representing a delivery is classified into an interesting or non-interesting segment based on detection of events namely boundaries and wickets. Due to the high frequency of ads and replays in cricket, we have proposed robust algorithms for their removal. Finally, we have proposed a finite state automaton based modeling of the temporal segments to extract key-frames. We have also extended the framework to include text cues and expert choices and also developed a hierarchical summary. We have tested our algorithm on several broadcast cricket videos and obtained good results.

Time-motion analysis of test and one-day international cricket centuries

The aim of this study was to quantify movement patterns of batsmen scoring 100 runs (century), including analysis at 50, 80, and 100 runs, in Test and One-Day international (one-day) matches and between the first and second 50 within a Test century. Test centuries (n = 13) and one-day scores above 80 (n = 12) filmed during the 2005 - 2006 Australian international season were analysed for movement patterns of standing, walking, jogging, striding, sprinting, shot playing, and turning. At each run target, differences in total time, duration of individual movement pattern, movement pattern frequency, and number of balls faced were determined between Test and one-day matches (analysis of variance). Differences within Test centuries were assessed using paired t-tests. A similar fractional predominance of time spent in low-intensity activity (standing and walking) between Test and one-day matches at each run target (94 and 96% respectively) was observed, with no differences in duration of striding or sprinting (Test: 1.1 min, s = 0.5; one-day: 0.9 min, s = 0.5 for sprinting: P = 0.28). A 37% longer total duration occurred in Tests, resulting in longer recovery bouts between high-intensity efforts. There were no differences between the first and second 50 runs of a Test century for any measure (P at best = 0.34). In summary, Test and one-day centuries are characterized by much low-intensity activity and patterns of high-intensity activity similar to many repeat-sprint team sports and greater recovery breaks in longer matches.

The professionalisation of Australian women's cricket: new times and new opportunities

When the Australian Women’s Cricket Team defeated the West Indies in 2013, to win their 5th World Cup from eight attempts, they reaffirmed their status as one of Australia’s most successful international teams. Victory in the 2015 Ashes series, in England, further reinforced their pre-eminent world status. During this time, significant changes also occurred off the field. Cricket Australia introduced pay increases of up to 150% for international and state level players. The sustained success of the national team is attributed to the rapid growth of participation in women’s cricket (up 18% 2013 - 2014), a trend that has resulted in females making up almost 25% of all cricket participants across Australia. On face value, the burgeoning profile of women’s cricket across Australia is cause for celebration. It is against this backdrop that Cricket Australia faces a range of enduring and emerging issues in the provision and promotion of the women’s game. With so many changes and adaptations occurring across the game, we chose to limit the focus of this research to the elite level. Among the enduring issues that are understood at this level are persistently high attrition rates amongst elite and aspiring players and large age differences across teams and squads. A further point of difference in the men’s and women’s games is that female teams are largely supervised by male coaches and support staff.

Prevalence of health promotion policies in sports clubs in Victoria, Australia

In recent years, some health agencies offered sponsorship to sporting associations to promote healthy environments by encouraging clubs to develop health-related policies. However, the extent to which these sponsorship contracts reach their stated aims is of concern. This study aimed to quantify levels of policy development and practice in sports clubs for each of five key health areas, namely smoke-free facilities, sun protection, healthy catering, responsible serving of alcohol and sports injury prevention. Representatives from 932 Victorian sports clubs were contacted by telephone with 640 clubs (69%) participating in the survey. Results suggested that the establishment of written policies on the key health areas by sports clubs varied widely by affiliated sport and health area: 70% of all clubs with bar facilities had written policies on responsible serving of alcohol, ranging from 58% of tennis clubs to 100% of diving and surfing clubs. In contrast, approximately one-third of sports clubs had a smoke-free policy, with 36% of tennis, 28% of country football and 28% of men's cricket clubs having policy. Moreover, 34% of clubs overall had established sun protection policy, whereas clubs competing outside during summer months, [diving (86%) and life-saving (81%)] were most likely to have a written sun protection policy. Injury prevention policies were established in 30% of sports clubs, and were most common among football (56%), diving (43%) and life-saving (41%). This study suggests that policy development for health promotion can be achieved in sports clubs when it is well supported by health agencies and consideration is given to the appropriateness of the specific behaviours to be encouraged for a given sport. Communication between associations and clubs needs to be monitored by health agencies to ensure support and resources for policy development to reach the club level.

The group purchasing process : an investigation into the influence of the facilitator in alpine tourism

Group travel is a common feature of all tourism markets and can vary from the familiar peer group/common purpose associations of the football and cricket followers to the non-familiar co-operative travel group of the under 35 year olds bus adventures throughout Europe. This study investigates the nature of social group travel in alpine tourism. It specifically examines the phenomena of the "group facilitator"; the person within the group who takes a major role in the travel decisions and organisation on rehalf of all the other members in the travel party. The specific activities of this "group facilitator" and the role of opinion leadership, information search, organisation process, previous experience, relationship ties between the group members are examined. The 'facilitator' also influences other individuals' decision to participate who delegate selection of destination to this person as well. The 'facilitator' has many of the characteristics of an opinion leader and was recognised by group participants as a major source of information about the destination. The findings of the study have important implications for tourism marketers as they highlight an opportunity to reach many potential travellers by directly targeting one key influencer and decision maker.
