Research on union renewal often cites a critical role for lay activism. This study examines determinants of activism and activism intentions among a broadly representative sample of U.S. union members. Hypotheses are developed from theory and previous research on union commitment and participation. Results for current activism are generally consistent with prior work. Extending the model to future intentions to help with organizing, an interesting contrast is that pro-union attitude influences appear much more important than do union instrumentality perceptions. This suggests that “covenant” rather than “exchange” concerns are more salient for this form of activism. Findings for ideological orientation support this interpretation. 相似文献

In the process of eating, everyone cooks, personally combining ingredients at hand to enhance appetite; but few are called cooks. From this mundane example we can take a new approach to the study of material status. A sociological formula that credits capital as opposed to labor with the source of advantage will obscure the dynamics shaping material status. Drawing on a study of the Hollywood area of Los Angeles, I indicate how, at the lowest and highest levels, people make their material status by innovatively combining what they have, as passively available resources, and what they do in the nature of hourly or task paid labor. The shift of theory from nouns, like labor and capital, to the active and passive verbs, “doing” and “having,” leads to a shift in the search for explanations of status differences. As in cooking, the transformative tricks critical for producing savory results are not simply in the recipes handed down from generation to generation but in those cooked up, in the innovative interactions in relating working for pay and the exploitation of ongoing relations. 相似文献

Using data from age 3 of the Fragile Families and Child Wellbeing Study, the current study explores the complex relationships between U.S. childcare subsidies and neglect. Specifically, the study examines two research questions: (i) Are U.S. childcare subsidies associated with self‐reported neglect among low‐income mothers? (ii) What individual types of self‐reported neglect are significantly reduced by receipt of childcare subsidy? Using negative binomial regression examining the relationships among mothers who were income‐eligible for childcare subsidy, we found that childcare subsidy was associated with lower levels of supervisory neglect, indicating an important role of subsidy in the lives of low‐income families. 相似文献

This study investigates the mass media's coverage of sexual topics during the years 1950, 1960, and 1970. An examination is made of the quantity of references to sex, the percentage of liberal references, and the coverage of specific sexual activities. It is ascertained that specific references to extramarital sex and noncoital sex decreased from 1950 to 1970. References both to sex relations leading to pregnancy and to sexual deviance have doubled in the number and percentage of total sexual references in this same period. The possible effects of the activities of special interest groups in altering the mass media's coverage of sexual activities is also taken into consideration. 相似文献

Abstract Because of the increasing prevalence of eating disorders in college populations, it is increasingly important for student health services to identify affected individuals. Therefore, the authors analyzed the student health forms of member schools of the New York State College Health Association for the presence of items that would identify an eating disorder. Directors of health services that include specific questions about eating disorders on health forms were then surveyed for their opinions about this practice. Specific items about eating disorders (anorexia nervosa, bulimia, vomiting to lose weight, laxative use to lose weight) were included on 5 of 111 forms. Less specific items including dissatisfaction with weight, being on a diet, or binge eating appeared on 10% of forms. Approximately one-third of the students known by health service staffs to have an eating disorder reported this on their health form, when provided a specific opportunity to do so. Even though underreporting by students is potentially a problem in such circumstances, the health service directors all recommended the inclusion of items relating to eating disorders on student health forms. “Human Papillomavirus Type 16 and Early Cervical Neoplasia,” CHRISTOPHER P. CRUM, et al. Flat warts (condylomata) of the uterine cervix are sometimes cytologically atypical and have abnormal mitotic figures; they are thought to be possible precursors of cancer of the cervix. Flat warts are caused by any of a number of types of human papillomaviruses (HPVs), one of which (HPV 16) has been previously associated with invasive cancer of the cervix. To determine whether HPV 16 is also associated with flat warts with abnormal mitoses, we analyzed 23 flat warts by DNA-hybridization techniques for the presence of HPV 16 and other HPV types, and correlated the results with the histology. Of 10 lesions with abnormal mitotic figures, 7 contained HPV 16, and 1 contained another type of HPV. Of 13 lesions without abnormal mitotic figures, only 1 contained HPV 16, and 7 contained other types of HPV. We conclude that the presence of HPV 16 correlates with the presence of abnormal mitotic figures in flat warts of the cervix, and that this type of flat wart is a precursor of invasive cancer of the cervix.

The first of the baby boomers have reached retirement age, but some have retired ‘early’ with varying degrees of personal choice. Preparation for retirement can lead to well-being in later life, but few studies have considered the preparations of involuntary retirees or the pathways that link their preparations with retirement outcomes. This research draws on a sample of 304 retirees from the Ageing Baby Boomers in Australia Study (2009) to examine how preparedness for retirement relates to voluntary and involuntary retirees' life satisfaction and how this relationship is explained by psychological, activity-based, and economic theories. Preparedness predicted life satisfaction for voluntary and involuntary retirees and each of theoretical pathways was supported. Although those retiring involuntarily were less prepared than voluntary retirees, their preparatory behaviours were still associated with life satisfaction. These results suggest that retirement policy and planning initiatives should aim to facilitate a holistic approach to retirement planning for future retirees, particularly those facing an early and unexpected retirement. 相似文献

Some viruses cause tumor regression and can be used to treat cancer patients; these viruses are called oncolytic viruses. To assess whether oncolytic viruses from animal origin excreted by patients pose a health risk for livestock, a quantitative risk assessment (QRA) was performed to estimate the risk for the Dutch pig industry after environmental release of Seneca Valley virus (SVV). The QRA assumed SVV excretion in stool by one cancer patient on Day 1 in the Netherlands, discharge of SVV with treated wastewater into the river Meuse, downstream intake of river water for drinking water production, and consumption of this drinking water by pigs. Dose–response curves for SVV infection and clinical disease in pigs were constructed from experimental data. In the worst scenario (four log10 virus reduction by drinking water treatment and a farm with 10,000 pigs), the infection risk is less than 1% with 95% certainty. The risk of clinical disease is almost seven orders of magnitude lower. Risks may increase proportionally with the numbers of treated patients and days of virus excretion. These data indicate that application of wild‐type oncolytic animal viruses may infect susceptible livestock. A QRA regarding the use of oncolytic animal virus is, therefore, highly recommended. For this, data on excretion by patients, and dose–response parameters for infection and clinical disease in livestock, should be studied. 相似文献
