Modelling and simulation for one‐day cricket

This article is concerned with the simulation of one‐day cricket matches. Given that only a finite number of outcomes can occur on each ball that is bowled, a discrete generator on a finite set is developed where the outcome probabilities are estimated from historical data involving one‐day international cricket matches. The probabilities depend on the batsman, the bowler, the number of wickets lost, the number of balls bowled and the innings. The proposed simulator appears to do a reasonable job at producing realistic results. The simulator allows investigators to address complex questions involving one‐day cricket matches.

Using Conditioned Reinforcers to Improve Behavior-Change Skills: Clicker Training for Practitioners

We evaluated the use of a clicker sound as a conditioned reinforcer to teach behavior interventionists appropriate clinical skills during in-situ training. A multiple-baseline-across-behaviors design indicated that the intervention was effective in increasing all target behaviors for all participants. For two of the participants, we conducted maintenance probes one to five weeks after the final training session and performance continued to occur at a high level. Although the participants ranked the contingent clicker presentation as less disruptive and more fair than typical feedback methods, they ranked it as slightly less helpful, less worthwhile, and less pleasant than typical feedback methods. These findings suggest that clicker training can play a valuable role in training mental health professionals.     

Eating in: home, consumption and identity

Food is perhaps one of the most mundane and taken for granted parts of our everyday life, yet the ways we think about shopping, cooking and eating are actually intensively reflexive. This paper uses the example of food to explore questions of identity in relation to the specific cultural location of 'the home'. Using case study examples the paper illustrates some of the complex ways in which identities, throughout the lifecourse, are produced, articulated and contested through food consumption and the spatial dynamics of cooking and eating. In doing so the paper demonstrates that households, rather than being single units of food consumption, can be sites of multiple and sometimes contradictory consumption practices and that it is necessary to understand how patterns of eating are negotiated and contested within households in order to understand how the home functions as a 'consumption site'.     

Acquired immune deficiency syndrome projections in England and Wales: interplay of methodology and data

Since the late 1980s, regular monitoring of the human immunodeficiency virus epidemic in England and Wales has been carried out through the work of successive national working groups. One of their tasks has been to provide short-term projections of the incidence of acquired immune deficiency syndrome. In this paper the data and methods used in this projection work are reviewed and results critically assessed with the aim of highlighting the strong interaction between methodological developments and data acquisition.     

Celebrity and politics: Effects of endorser credibility and sex on voter attitudes,perceptions, and behaviors

While much research examines the effects of celebrity endorsements in commercial advertising, scholars have only recently sought to investigate the effects of celebrity endorsements of politicians on voter perceptions and behavior. This study expands existing research on celebrity political endorsement effects via an experiment exploring effects of different versions of a news story describing a celebrity's endorsement of a political candidate on participants’ voting attitudes, perceptions of candidate credibility, and voting behavioral intent. Although participants perceive credibility differences between high- and low-credibility celebrities, neither endorser credibility nor endorser sex impact attitudes toward the endorsed candidate, perceptions of the candidate's credibility, or intended voting behavior. Conceptual relationships to other studies on celebrity endorsement effects are discussed, as are implications, limitations, and directions for future research.     

The gendered dimensions of bushfire in changing rural landscapes in Australia

This paper examines gender differences in awareness, preparedness and attitudes towards bushfire amongst landholders in rural landscapes affected by amenity-led in-migration in southeast Australia. It considers the potential of conceptualising bushfire not as a gender-neutral natural phenomenon but as an important means by which traditional gender roles and power relations within rural landscapes are maintained. Landholders were found to uphold conventional views of bushfire management as “men’s business” despite changing social circumstances. Consequently, key gender differences exist within landholders’ bushfire risk awareness, bushfire knowledge, the perceived need for bushfire preparedness measures, the willingness to perform certain tasks, and the belief in personal capacity to act. We argue that covert and less visible as well as overt gender roles and traditions are important factors in understanding landholders’ engagement with bushfire management. When gendered dimensions of bushfire are investigated in the context of hegemony, a paradox emerges between women choosing not to take control of their own bushfire safety and women being denied the opportunity to take control. The complex and contradictory actions and attitudes to bushfire that materialise through an analysis of gendered social experiences complicate attempts to create more gender-sensitive frameworks for bushfire management. The tenacious and embedded nature of gender role divisions within both public and private spheres was furthermore found to act as economic, social and political stumbling blocks for empowerment opportunities. Using a mixed-methods research approach, this paper maps out gendered dimensions of bushfire through landholders’ narratives and actions. The implications of these dimensions for bushfire management have direct relevance to recent international discussions of the vulnerability of the growing number of people living in bushfire-prone rural–urban interface areas.     

Deconstructing place identity? Impacts of a “Racino” on Elora,Ontario, Canada

The heritage-scape is a socially constructed place that provides locally crafted products, cuisine, and experiences to satisfy consumers’ desire for authenticity. In this paper we question if the introduction of a functionally non-conforming structure causes an existing heritage-based place identity to dismantle (i.e. deconstruct). In 2003, a pari-mutuel racetrack and gaming parlour (a “racino”) was introduced to the historic village of Elora, Ontario, Canada. Through content analysis we unravel (i.e. deconstruct) the social processes that lay behind this development. We find that this profit-oriented venue was widely contested by preservation-minded residents, who expressed concern that this structure would compromise Elora’s heritage image. Our survey finds, however, that the majority of visitors believe that the Grand River Raceway and Slots has not impacted Elora’s existing place-based identity. Key informants further reveal that image management, spatial placement and visual coherence are largely responsible for its maintenance. We conclude that a heritage-based place identity may be retained, and even enhanced, in the presence of a hegemonic discourse that is underlain by a long-standing preservationist ideology.     

Optimal change-over designs for correlated observations

Design implications of an autoregressive model for change-over experiments are investigated. In this model, the residual effect due to the previous treatment is assumed to be proportional to the response in the previous period. In addition, the errors from the same experimental subject are assumed to be correlated according to a first-order autoregressive model. Models with fixed and random subject effects are discussed separately. An attempt has been made to identify and construct optimal or nearly optimal designs in various situations. Empirical conclusions of Taka and Armitage [Commun. Statist. Theor. Meth. (1983)12, 865-876] regarding the efficiency of some designs have also been confirmed.
