Interest in the structure and dynamics of sociology as a discipline has led to recurrent attempts to measure the prestige, productivity, and quality of education of the various sociology departments. While several previous papers have suggested the potential value of the Science Citation Index (SCI) as a measure of scientific standing, few attempts have been made to utilize a citation-based measure of scientific prestige. This paper considers the meaning of the citation in science and in stratification theory. Procedures are described whereby citations to individual sociologists and journals are employed to yield rankings of departments of sociology and journals. The differences between these rankings and other rankings are discussed.  相似文献

The exhibiting of the genitals by males has previously been defined as symptomatic of narcissism and infantile sexuality. Viewed as a developmental anomaly of emotional life, treatment has been focused upon stimulating personal development by working out the problems which have inhibited maturation. Results have been discouraging. As an alternative, defining the problem as symptomatic of disturbances in basic relationships and treating the current central relationships as the focus offers a strong opportunity for inducing satisfactory changes.  相似文献

This paper considers the problem of devising a single stage procedure for selecting the treatment combination associated with the largest interaction in a two-factor rfx× c experiment having independent normally distributed observations with common known variance. The intuitive procedure based on the best linear unbiased estimators of the population interactions is employed. Initially an indifference zone formulation is used; the problem of determining the least favorable configuration is reduced to a nonlinear programming problem with log concave objective function and a convex polytope as feasible region. A solution technique is introduced in the context of an illustrative example. The problem is also considered using a preferred population formulation; this approach requires a strengthened version of the indifference zone probability requirement. It is shown that the same sample size guarantees this requirement as does the earlier one.  相似文献

Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES.  相似文献

This study explores how third-plus-generation Mexican Americans are able to perpetuate Mexican ethnicity within the relatively integrated environments they occupy in and around Phoenix, Arizona and San Jose, California. By using an imaginary approach in this analysis, I seek to demonstrate the limited applicability of the symbolic ethnicity approach for this group, in particular, as well as to downplay thinking about culture as a set of traits or fixed characteristics that define an ethnic subgroup. I do this through an exploration of how the third-plus-generation Mexican Americans interviewed for this study utilize a range of relational resources—specifically, religion, Spanish-language television, and cross-national encounters—to reinforce and recreate Mexican ethnicity in their day-to-day lives.  相似文献

This article describes an outpatient treatment program for adolescent sexual abusers that was established by a mental health agency in collaboration with a specialized probation program in the juvenile court. Individualized treatment is based on a comprehensive clinical assessment with the youth and guardian, for which examples are provided. Given the heterogeneity of this population, we describe several treatment strategies directed to various individual or family clinical targets, including psychiatric disorders, sexual deviance and sexuality, normal adolescent development and adaptive skills, and parent and family relationships. Ongoing collaborative and coordination issues are also reviewed. The integration of mental health and probationary services provides a balanced approach to the community management and treatment of the low-risk, primarily first-time, adolescent sexual offender.  相似文献
