Colin Sumner has declared that the sociology of deviance as a research specialty was “dead? by 1975; later influential studies on norm-violating behavior appeared only in the specific area of criminology. We subjected this argument to empirical test through an analysis of the most-cited scholars and works in 263 textbooks, articles, and research notes appearing in the sociology of deviance from 1993 to 1999. We found some support for Sumner's claims: The majority of the most-cited scholars in devi-ance today conduct research in other areas, primarily in criminology. Furthermore, among the 31 most-cited works in our analysis, only two of 15 studies classified in the sociology of deviance appeared after 1975. We conclude with some thoughts about the factors that contribute to the rise and fall of research specializations in sociology.  相似文献

A number of settings arise in which it is of interest to predict Principal Component (PC) scores for new observations using data from an initial sample. In this paper, we demonstrate that naive approaches to PC score prediction can be substantially biased towards 0 in the analysis of large matrices. This phenomenon is largely related to known inconsistency results for sample eigenvalues and eigenvectors as both dimensions of the matrix increase. For the spiked eigenvalue model for random matrices, we expand the generality of these results, and propose bias-adjusted PC score prediction. In addition, we compute the asymptotic correlation coefficient between PC scores from sample and population eigenvectors. Simulation and real data examples from the genetics literature show the improved bias and numerical properties of our estimators.  相似文献

A framework outlining the potential impacts of conflict on demographic behaviour is used to analyse the post-conflict demography of Malian Tuareg after substantial conflict-induced social, political and economic changes. A remarkable stability in both fertility and marriage leads to the conclusion that an important demographic consequence of persecution and conflict may be an entrenchment of demographic behaviour which reinforces the population’s demographic identity particularly with respect to reproduction. The importance of unique historical, political and cultural experiences of a population in responding to conflict precludes the development of a ‘demography of conflict’, suggesting we should be pursuing the ‘demography of conflicts’.  相似文献

Social workers seeking licensure in most states must pass one of the four different written examinations developed by the American Association of State Social Work Boards (AASSWB). These examinations are claimed to be valid measures of professional social work knowledge and competence to practice. To test this claim, we administered the multiple-choice 50-item Advanced practice examination contained within the official AASSWB Advanced study guide to 42 first year MSW students. Weblanked out the actual question content, and asked the students to select the correct answers from among the four choices given. Chance would suggest that the average score should be about 25% correct (one out of four). In actualitythe students' scores averaged 37% correct, a statistically significant difference. These results challenge the content and discriminant validity of the AASSWB examination and call for further studies on the examinations' value.  相似文献

The likelihood-ratio test statistic for testing homogeneity of exponential means with an ordered alternative has a rather complex null distribution. Expressions for the mean and variance of its null distribution are derived, and the accuracy of a two-moment chi-squared approximation is studied. The coefficients needed to implement the approximation are tabled. The application of these results in testing for a constant versus a nondecreasing intensity in a nonhomogeneous Poisson process is also discussed.  相似文献

Select businesses in industry may attempt to compete through distinct strategies. But some may be successful in adopting distinct strategic profiles while others may not prove successful. In this study it was expected that six different groups of businesses might be present in the empirical exploration – those competing successfully with the low cost strategy and those competing unsuccessfully with this strategy; those competing successfully with the differentiation strategy and those competing unsuccessfully with this strategy; and those competing successfully with low cost and differentiation strategies and those competing unsuccessfully with these strategies. The results of the investigation portray the presence of three strategic profiles. They are unsuccessful low cost businesses with the lowest performance, unsuccessful differentiated businesses with the second lowest performance, and successful businesses with combination strategies with the highest performance.  相似文献

Most sociologists and penologists tend to shy away from studying inmate attitudes toward homosexuality and homosexuals. Researchers within the corrections field who focus on prison sexuality typically conduct their research on consensual samesex sexual behavior and sexual coercion. The focus of the present study, however, was to ascertain female inmates' attitudes toward homosexuality and homosexuals while exploring the role ofseveral predictor variables on their attitudes. Specifically, the authors examine the relationship between female inmate homosexual behavior and attitudes toward homosexuality and homosexuals. Because of the number of items pertaining to attitudes toward homosexuality and homosexuals, factor analysis was conducted to examine whether the items measured similar constructs. Results ofthe factor analysis revealed two distinct factors/issues:civil/personal rights and personal deviance models. The mostsalient, and only statistically significant, variables in the civil/personal rights model were age, homosexual activity prior to incarceration, and homosexual activity during incarceration. Homosexual behavior during incarceration was the only statistically significant predictor of the personal deviance model.  相似文献
