Scholars of bisexuality commonly agree that bisexuality as a distinct sexual identity remained invisible for epistemic reasons until the 1970s. This article examines this dominant explanation for the late invention of bisexual identity by discussing how bisexuality functioned in the homosexual movement in the Netherlands from 1946 to the early 1970s. This historical case study shows that in the Netherlands bisexuality as an identity existed in the movement in the first postwar decades and was erased in the late 1960s, not only for epistemic reasons but also for tactical ones. The article aims to contribute to a better insight into the history of bisexuality and the politics in the Dutch postwar homosexual movement.  相似文献

International student exchange is pursued by Australian schools of social work as a strategy to engage with the internationalisation agenda set by government, universities, and the profession. However, little concrete information about the nature and scope of these activities exists. The study reported here aimed to address this gap. Twenty-seven of the 30 Australian universities that offer social work programs participated in an online survey about international student exchange activities. The results indicate that a majority of schools (n?=?23) do engage in such activities, with international field placements the most frequent form of exchange. Exchanges are most likely to be facilitated and managed by social work staff. The findings, and their implications for the development of good practice in international student exchange, are discussed. This research provides a “point-in-time” snapshot of international exchange in Australian social work education and a benchmark for future analyses of this expanding practice in the profession.  相似文献

The role of trust has been argued to play an increasingly important role in modern, complex, and ambivalent risk societies. Trust within organizational research is anticipated to have a general strategic impact on aspects such as organizational performance, communication and knowledge exchange, and learning from accidents. Trust is also an important aspect related to regulation of risk. Diverse regulatory regimes, their contexts and risks influence regulators use of trust and distrust in regulatory practice. The aim of this paper is to discuss the relationship between risk regulation and trust across diverse risk regulation regimes. By drawing from studies of risk regulation, risk perception, and trust the purpose is to discuss how regulation and trust are linked and used in practice to control risk across system levels in socio-technical systems in high risk industries. This paper provides new knowledge on 1) how functional and dysfunctional trust and distrust are grounded in the empirical realities of high risk industries, 2) how different perspectives on trust and distrust act together and bring new knowledge on how society control risk.  相似文献

This article explores whether mothers’ perceived control over their own workplace flexibility options has any relationship to their satisfaction with their husbands’ contributions to household labor in the United States. We hypothesize that flexibility enhances their ability to more adeptly engage in role management in multiple life areas, thus enabling them to be more satisfied with their partners’ domestic input as well. We use a unique data set of 1,078 randomly sampled women involved in mothers’ organizations that generally attract members based on their current level of participation in the paid labor market. We then link nine distinct workplace flexibility policies with mothers’ satisfaction related to their husbands’ participation in all household tasks, as well as a subset of female-typed tasks. We find that across both arrays of tasks, mothers with more perceived control over work-related schedule predictability and those that had the ability to secure employment again after an extended break had higher levels of satisfaction with their husbands’ participation in household labor. In addition, short-term time off to address unexpected needs was important for all tasks considered together only.  相似文献

Urbanization can alter the composition of arthropod communities. However, little is known about how urbanization affects ecological interactions. Using experimental colonies of the black bean aphid Aphis fabae Scopoli reared on Vicia faba L, we asked if patterns of predator-prey, host-parasitoid and ant-aphid mutualisms varied along an urbanization gradient across a large town in southern England. We recorded the presence of naturally occurring predators, parasitoid wasps and mutualistic ants together with aphid abundance. We examined how biotic (green areas and plant richness) and abiotic features (impervious surfaces and distance to town center) affected (1) aphid colony size, (2) the likelihood of finding predators, mutualistic ants and aphid mummies (indicating the presence of parasitoids), and (3) how the interplay among these factors affected patterns of parasitoid attack, predator abundance, mutualistic interactions and aphid abundance. Aphid abundance was best explained by the number of mutualistic ants attending the colonies. Aphid predators responded negatively to both the proportion of impervious surfaces and to the number of mutualistic ants farming the colonies, and positively to aphid population size, whereas parasitized aphids were found in colonies with higher numbers of aphids and ants. The number of mutualistic ants attending was positively associated with aphid colony size and negatively with the number of aphid predators. Our findings suggest that for insect-natural enemy interactions, urbanization may affect some groups, while not influencing others, and that local effects (mutualists, host plant presence) will also be key determinants of how urban ecological communities are formed.  相似文献

Women who participate in mixed-gender, antifeminist movements are not a homogeneous group of actors who face no identity-based conflicts when they mobilize for these causes. Using 23 in-depth interviews with women involved in the American fathers' rights movement—which has as its goal the reformation of child support and child custody laws in ways that are more favorable to men and less favorable to women—I argue that mixed-gender, antifeminist activism has the potential to produce high levels of tension for female participants between their various social identities and their collective movement identity. Indeed, almost half of these women elaborate on how two particular manifestations of their social identities—as simultaneous members of other feminist groups and simply as women—clash with the collective identity generated by the fathers' rights movement. Ultimately, these women coped with these competing allegiances in a variety of proactive ways. In contrast, the other half of the sample experienced no such tensions. These differential patterns of identity-based conflicts are suggestive of the hazards associated with a social movement's efforts to attract a wider membership base over time.  相似文献

Despite consistent evidence to suggest that participating in leisure is associated with perceived health status among older adults, there have been few attempts to determine the possible underlying mechanisms in this relationship, including the role of quality of life (QoL). This study examined the role of perceived quality of life in the relationship between leisure and perceived health in older women. Correlations, regression, and mediation analysis were conducted on data from the Woman’s College Alumnae Women’s Health Study. Results indicate that QoL partially mediates the relationship between leisure and perceived health in older women. Findings further establish the link between leisure and perceived health with QoL playing an important role in the relationship.  相似文献

Infants amass thousands of hours of experience with particular items, each of which is representative of a broader category that often shares perceptual features. Robust word comprehension requires generalizing known labels to new category members. While young infants have been found to look at common nouns when they are named aloud, the role of item familiarity has not been well examined. This study compares 12‐ to 18‐month‐olds’ word comprehension in the context of pairs of their own items (e.g., photographs of their own shoe and ball) versus new tokens from the same category (e.g., a new shoe and ball). Our results replicate previous work showing that noun comprehension improves rapidly over the second year, while also suggesting that item familiarity appears to play a far smaller role in comprehension in this age range. This in turn suggests that even before age 2, ready generalization beyond particular experiences is an intrinsic component of lexical development.  相似文献

Objective: This study examined how freshman year substance use prospectively predicted time to college graduation, and whether delayed graduation predicted postponed adoption of adult roles and future substance use. Participants: Participants were part of a longitudinal study that began in 2004. The first analyses focused on freshman year (N = 2,050). The second analyses corresponded to a subset of participants at age 27 (N = 575). Methods: Measures included self-reported substance use, adult role adoption, and university reported graduation dates. Results: Results indicated that frequent binge drinking and marijuana use during freshman year predicted delayed college graduation. Those who took longer to graduate were more likely to have lower incomes and were less likely to obtain a graduate degree. Taking 5–6 years to graduate was associated with greater likelihood of alcohol-related problems. Conclusions: Findings support the importance of interventions during freshman year of college to decrease substance use and promote timely graduation.  相似文献

Sexual health research often relies on single risk indicators. However, multi‐variable composites may better capture the underlying construct of risk‐taking. Latent Profile Analysis identified subgroups based on condom use consistency, partner numbers, and sex frequency among 605 adolescents. Three profiles were identified for each of grades 8 to 10 (Condom Users, Few Partners, and Risk‐Takers) and 4 in grades 11 and 12 (Condom Users, One Partner, Two Partners, and Risk‐Takers). Inconsistent condom use groups reported more non‐condom (and often less effective) birth control use and STD and pregnancy histories. Females had greater representation in the Few Partners, One Partners, and Two Partners groups, which also contained increasing proportions of participants in each subsequent year. Males had greater representation in the Risk‐Takers group. A profile approach to measurement has methodological advantages, can add to substantive knowledge, and can inform content, timing, and targets of sexual health interventions.  相似文献
