Alcohol consumption and its relationship to gambling was examined in a statewide New Mexico survey in 1996 and 1998. Data
regarding both drinking habits and gambling behavior were obtained from a stratified random sample of the adult population
(N = 2674) across the entire State of New Mexico via phone survey. These surveys were carried out shortly after a period when
New Mexico experienced an initial surge in the legalized gaming industry. Fifty-seven percent of survey respondents reported
drinking in the past month, while 43.1% reported no drinking in the past 30 days. Results show that while the number of days
in the past 30 that a person drinks is significantly correlated with some types of gambling behavior (e.g., in 1998, drinking
more days was associated with more card gambling and sports gambling), it is the amount of alcohol consumed per occasion that
is associated with more gambling behavior. For example, in both 1996 and 1998, drinking more per occasion was associated with
more sports betting, dice gambling, number/lottery gambling, gambling using machines, and paper game gambling (e.g., pull
tabs, punchboard). These results suggest that problem gambling behavior is not affected as much by the number of occasions
on which one consumes alcohol, as by the amount of alcohol consumed per occasion. 相似文献

The standard deviation of the average run length (SDARL) is an important performance metric in studying the performance of control charts with estimated in-control parameters. Only a few studies in the literature, however, have considered this measure when evaluating control chart performance. The current study aims at comparing the in-control performance of three phase II simple linear profile monitoring approaches; namely, those of Kang and Albin (2000), Kim et al. (2003), and Mahmoud et al. (2010). The comparison is performed under the assumption of estimated parameters using the SDARL metric. In general, the simulation results of the current study show that the method of Kim et al. (2003) has better overall statistical performance than the competing methods in terms of SDARL values. Some of the recommended approaches based solely on the usual average run length properties can have poor SDARL performance. 相似文献

Methods based on scan statistics are widely used in health-related applications to detect clusters of disease. The most common methods are based on the Bernoulli and Poisson models. Kulldorff (1997) derived the likelihood ratio test statistic for his scan method for both of these models. His scan statistic is widely used with freely available software, SaTScan? (see Kulldorff, 2005). We provide an alternative derivation of the likelihood ratio test statistic in the Poisson case. Our derivation is simpler and more general in the sense that it applies when the incidences are not aggregated into subregional counts. 相似文献

Average run lengths of the zone control chart are presented, The performance of this chart is compared with that of several Shewhart charts with and without runs rules, It is shown that the standard zone control chart has performance similar to some even simpler charts and a much higher false alarm rate than the Shewhart chart with all of the common runs rules. It is also shown that a slightly modified zone control chart outperforms the Shewhart chart with the common runs rules. 相似文献

In the UK, human resource practitioners and academics alike are becoming more aware of the emergence of managing diversity. But what does managing diversity actually mean, how does it translate into practice, and what does it matter? The following paper briefly debates the rhetoric of managing diversity and considers whether managing diversity is a distinct approach to managing people or a means of diluting equal opportunities in UK organizations. With respect to the realities of the concepts in UK organizations, empirical data from a survey of sixty UK human resource professionals and general line managers is presented. We pose a number of cautionary questions, including what does it matter and to whom? By doing so we intend to encourage further critique and challenges in respect to the concept of managing diversity in organizations. 相似文献

Bayesian control charts have been proposed for monitoring multivariate processes with the multivariate exponentially weighted moving average (MEWMA) statistic. It has been suggested that we use limits based on the predictive distribution of the MEWMA statistic. This analysis, however is based on the erroneous result that the average run length (ARL) is a function of the exceedance probability, that is, the probability that the first point exceeds the control limit. We show how this result can be corrected and we discuss how the Bayesian MEWMA chart with limits based on the predictive distribution compares with other multivariate control chart procedures. 相似文献

Previous research on the effects of vocal rate on credibility and persuasion has not carefully considered several methodological and theoretical issues. An investigation was conducted that controlled for a number of methodological factors, and considered different explanatory possibilities. Results indicated more complex and constrained relationships between rate of vocalization, credibility, and persuasion than some previous research had found, and were consistent with research in the person perception literature. Support for a straightforward credibility bolstering explanation was not found, and other explanatory rationales were considered. 相似文献

Previous research has not considered the effects of nonverbal synchronization by a speaker on message processing and acceptance by a listener. In this experiment, 178 subjects watched one of three versions of a message—high synchrony, minimal synchrony or dissynchrony—presented by one of two speakers. Receivers of the high synchrony message, which employed kinesic cues synchronized to the vocal/verbal stream, showed higher recall of the message and were more persuaded by it than receivers of the dissynchronous message, which had kinesic cues out of sync with the vocal/verbal stream. Results on three other dependent measures—credibility, distraction and counterarguing—were mixed but were generally consistent with the credibility-yielding and distraction-yielding formulations outlined. 相似文献
