This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia. 相似文献

Natural history, observational, and interview data from a study of two anti-pornography crusades and the social movement organizations which created and directed them are used to assess nine propositions formulated by Zald and Ash (1966) concerning the structure and dynamics of social movement organizations. The Zald-Ash propositions were formulated from the literature on national, established social movement organizations. This paper explores the applicability of the propositions to those organizations which are small and emerging. The propositions are generally supported. Discrepancies are accounted for by the significant influence of leadership orientation, goal specificity, and incentive structure in determining other structural and dynamic characteristics of small or emerging social movement organizations. 相似文献

Effective targeted and community HIV/STD prevention programs 总被引:1,自引:0,他引:1
Community interventions and interventions targeting specific groups at risk of STDs/HIV have demonstrated significant impacts on sexual behavior, particularly condom use and safer sex. The scientific evidence suggests the factors that make these interventions particularly effective include the establishment of community, including business and CBO partnerships; maintainance of the intervention post-research funding; and buy-in by the community or target group. The modification of risky normative beliefs through the use of opinion leaders and role models, and through intervention delivery by peer educators, is an important facet of such interventions. Interventions delivered by health professionals, absent a community base, appear to be unsuccessful. Where cultures or subcultures are targeted, the close involvement of such groups in the design and delivery of messages is critical to their success. Diffusion of interventions through existing social networks further extends the intervention into the community and acts to reinforce and maintain changes in peer norms toward safer sexual behavior. The available data confirm that community or medical infrastructure-based interventions are effective in changing sexual behavior and can reach a wider range of the population than face-to-face programs if they incorporate peer educators as role models in modifying norms, and if diffusion of the intervention is integral to the design. 相似文献

Using data from the Longitudinal Study of American Youth (LSAY), hierarchical linear models (HLMs) were used to model the growth of student science achievement in three areas (biology, physical science, and environmental science) during middle and high school. Results showed significant growth in science achievement across all areas. The growth was quadratic across all areas, with rapid growth at the beginning grades of middle school but slow growth at the ending grades of high school. At the student level, socioeconomic status (SES) and age were related to the rate of growth in all areas. There were no gender differences in the rate of growth in any of the three areas. At the school level, variables associated with school context (school mean SES and school size) and variables associated with school climate (principal leadership, academic expectation, and teacher autonomy) were related to the growth in science achievement. Initial (Grade 7) status in science achievement was not associated with the rate of growth in science achievement among either students or schools in any of the three areas. 相似文献

Characteristics of effective providers of marital and family therapy in rural mental health settings
Characteristics of effective providers of marital and family therapy (MFT) in rural mental health settings were investigated. The survey sample included 74 members of the National Association for Rural Mental Health who, through a modified Delphi process, created a composite picture of effective MFT providers. The findings yielded six major rank-ordered characteristics of effective MFT providers in rural mental health settings, with effective skills in MFT ranked first. Rural community understanding, appreciation and participation ranked second. Specific competencies contributing to each major characteristic were also identified and are discussed. Recommendations for use of this information are provided. 相似文献

Stalking is relatively common yet little is known of the longer-term health effects of stalking. Using the National Violence Against Women survey, we estimated lifetime stalking victimization among women and men, ages 18 to 65, identified correlates of being stalked, and explored the association between being stalked and mental and physical health status. With a criterion of being stalked on more than one occasion and being at least "somewhat afraid," 14.2% of women and 4.3% of men were victims. Among those stalked, 41% of women and 28% of men were stalked by an intimate partner. Women were more than 13 times as likely to be "very afraid" of their stalker than men. Negative health consequences of being stalked were similar for men and women; those stalked were significantly more likely to report poor current health, depression, injury, and substance use. Implications for victims, service providers, and the criminal justice system were reviewed. 相似文献
