Bingo is one of the most popular and most accepted forms of gambling in the United States today. Yet, despite its popularity, many bingo players are not completely comfortable with the moral rightness of their actions. This participant observation and interview study spanning a 5 year period shows how bingo players use superstitious strategies, such as feelings, hunches and psi, attitudes, and luck to neutralize their marginally deviant behaviors. 相似文献

Rick was an ambitious entrepreneur beginning the first of several businesses at age 16. He amassed a fortune by age 35. Between the ages of 42 and 50, his gambling rampage liquidated his assets, he lost his business and license to practice in his field, and he ended up in debt of over $1 million. Today at age 53 he is starting a new career in counseling and working with compulsive gamblers. 相似文献

"Two models, the U.S. census model and the latent-class model, are compared in their application to evaluating measurements of ethnicity. Although the census approach assumes that the response categories of a questionnaire item correspond to groups in the population, the latent-class approach seeks to assess whether any set of response categories can represent observed ethnic heterogeneity. Data collected using the 1990 census Hispanic-origin question and other instruments for measuring ethnicity suggest that the latent-class approach is superior whenever the response categories are not known to be valid. In particular, using the latent-class model, this article rejects the census model's assumption of a single dimension of meaning underlying responses to the Hispanic-origin question." 相似文献

"This article tests assumptions invoked in the demographic literature to estimate the population distribution of fecundability from data on waiting times to first conception. In continuous time, the key assumption is that waiting times are realizations from a mixture of exponentials distribution. In discrete time, the key assumption is that waiting times are realizations from a mixture of geometrics distribution. The [U.S.] Hutterite data analyzed by Sheps (1965) are consistent with this assumption. Various models, however, have one representation in mixture of exponentials form. A fundamental identification problem plagues the conventional estimation procedure. Our analysis calls into question the conventional practice of checking model specification by using goodness-of-fit tests. The practical importance of the identification problem in duration models is demonstrated." 相似文献

Doctors are not health care providers, and medicine is not a commodity. To practice medicine well, the doctor must attend to each patient as a whole person and be faithful in giving care when cure is not possible. 相似文献
