Superstitious Beliefs in Gambling Among Problem and Non-Problem Gamblers: Preliminary Data

Superstitious beliefs, defined as a strong conviction based on the erroneous perception of a cause-effect association between two independent events, are considered to play an instrumental role in the maintenance of gambling behaviour. In this preliminary study, responses to eight items assessing superstitious beliefs were compared among 56 electronic gaming machine (EGM) problem gamblers, 22 non-problem EGM and 23 non-EGM non-problem gamblers. Results suggested that problem gamblers endorsed more superstitious beliefs than non-problem gamblers and that such beliefs were correlated with gambling intensity. Further research is required to determine if superstitious beliefs represent a vulnerability factor for the development of problem gambling or emerge as a consequence of involvement in gambling.     

Semiparametric Bayesian Inference for Time Series with Mixed Spectra

A Bayesian analysis is presented of a time series which is the sum of a stationary component with a smooth spectral density and a deterministic component consisting of a linear combination of a trend and periodic terms. The periodic terms may have known or unknown frequencies. The advantage of our approach is that different features of the data—such as the regression parameters, the spectral density, unknown frequencies and missing observations—are combined in a hierarchical Bayesian framework and estimated simultaneously. A Bayesian test to detect deterministic components in the data is also constructed. By using an asymptotic approximation to the likelihood, the computation is carried out efficiently using the Markov chain Monte Carlo method in O ( Mn ) operations, where n is the sample size and M is the number of iterations. We show empirically that our approach works well on real and simulated samples.     

Rule enforcement in a public setting: The case of basketball officiating

This participant observation study examines some of the definitional and dramaturgical work performed by basketball officials attempting to enforce formal rules in the presence of audiences (e.g., spectators, coaches, players and fellow officials). Our analysis begins with the discovery that officiating requires participation in both a real world of physical events and objects, and a social world of subjective identifications. Second, we explore the contexts of legitimation by which decisions are justified. Third, we identify dramaturgical strategies used by officials to enhance legitimacy in the face of problematic decisions. Finally, we consider the assumptions officials make about the character of their work. The paper concludes with a discussion of indexical and interpretive features of organizational and bureaucratic use of formal rules, including the case of basketball officiating.An earlier draft of this paper was presented at the annual meeting of the Southern Sociological Society, Knoxville, Tennessee, March, 1980. We would like to thank Michael Hughes and James Michaels for abetting suggestions and comments. The authors share equal responsibility for the paper; the names have been listed alphabetically.     

Violence towards caregivers of persons with developmental disabilities

OBJECTIVE: Violent and disruptive acts committed by persons with developmental disabilities are a potential work environment problem for caregivers. This study developed and tested an instrument for describing and analyzing violence among persons with developmental disabilities. METHODS: Personnel from four units of one facility recorded daily on a simple form all violent and disruptive acts occurring in a limited range of situations. RESULTS: Acts of violence were associated with a small minority of individuals, but grossly underreported and unrecognized in formal reporting systems. None of the nearly 3000 incidents recorded during the six-week study required sick leave. Violent and disruptive acts occurred most often when an individual was requested to do something he or she did not want to do, when the individual was denied the opportunity to do something they did want to do and when waiting or under-stimulated. Personnel used the data in discussing countermeasures that could be integrated with the care and treatment of the individual. CONCLUSION: Hitting, kicking, pinching etc. of personnel are a work environment problem due to their high frequency and effects upon employee morale. The instrument and procedures can be used to reduce incidents of violence, which would improve the working environment of employees and assist persons with developmental disabilities as they move from institutional environments.
