This paper explores social movement organizing within social institutions, using the cases of the Surrey book banning and the Trinity Western University, two cases of activist litigation in British Columbia, Canada. In these cases, lesbian and gay teacher activists challenged heteronormative constructions in educational practices, in one case by introducing lesbian and gay-positive reading materials in the elementary grades, in the other by challenging the right of an evangelical university to train teachers for the public education system. In the context of the existing literatures on social movements within institutions and challenges to education practices, the paper emphasizes two main conclusions: 1) challenges to educational practice may be mounted by teachers themselves, despite their professional and 'insider' status and 2) a range of different types of relationships are possible between social movement challenges within social institutions and social movements outside of institutions. In the cases presented here, the strategies, discourses and frames of 'insider' challenges to educational practices were drawn from the teacher-activists' location as part of the broader legally focused Canadian lesbian and gay movement.  相似文献

This paper analyzes the impact of the financial and economic crisis on migration within Europe and towards Germany. The crisis has triggered a diversion of migration flows from the new EU Member States to prospering countries such as Germany rather than a large increase of migration from the mainly affected countries. Novel estimation procedures, which consider systematically conditions in alternative destinations, show that the overwhelming share of the migration surge in Germany can be attributed to the deterioration of economic conditions in alternative destinations. Furthermore, micro data from the new IAB-SOEP migration sample demonstrate that the share of individuals who did not immigrate from their birth countries in all arrivals has significantly increased since the begin of the crisis. The share of individuals, who have been non-employed before their arrival in Germany, has not increased in the course of the crisis. However, average education levels of new arrivals have declined.  相似文献

In this paper, measurements from experiments and results of a finite element analysis (FEA) are combined in order to compute accurate empirical models for the temperature distribution before a thermomechanically coupled forming process. To accomplish this, Design and Analysis of Computer Experiments (DACE) is used to separately compute models for the measurements and the functional output of the FEA. Based on a hierarchical approach, a combined model of the process is computed. In this combined modelling approach, the model for the FEA is corrected by taking into account the systematic deviations from the experimental measurements. The large number of observations based on the functional output hinders the direct computation of the DACE models due to the internal inversion of the correlation matrix. Thus, different techniques for identifying a relevant subset of the observations are proposed. The application of the resulting procedure is presented, and a statistical validation of the empirical models is performed.  相似文献

Around a third of Asian migrants to Australia self-identify as Christians, and many join churches where they meet fellow migrants and other Australians. Churches might thus be places that can foster the integration of Asian migrants into Australian society. This paper uses social network and social capital theory to examine the prevalence of bonding and bridging among 61,386 churchgoers from 2135 Protestant churches who completed the Australian National Church Life Survey in 2011. We compared levels of bonding and bridging social ties of first-generation Asian migrants (FGAM) with Australians born of Australian-born parents (ABOAP). FGAM joining congregations had fewer social ties than ABOAP, and developed bridging (but not bonding) more slowly. FGAM had lower bonding but higher bridging in MonoAnglo congregations compared with Multicultural or MonoAsian congregations. The results suggest that FGAM who are in MonoAnglo churches may be less tightly bound to their congregation, but more likely to bridge beyond it, than are FGAM in multicultural or largely Asian congregations.  相似文献

The aim of the study was to identify the unique support needs and preferences of African refugees in Canada. In‐depth interviews were conducted with Sudanese and Somali refugees (n=68) living in two cities in central and western Canada. Refugees were interviewed individually to identify their support needs, current sources of support, available support programmes, barriers to access to support resources, and preferred support interventions. These refugees reported major support needs, depleted social networks, and barriers to accessing services and supports. They identified distinct preferences for support from peers from the same country of origin and professionals. Participants wanted group‐level support supplemented by one‐to‐one support. Transportation, child care, meals, and peers matched by language and gender were recommended to enhance accessibility to support programmes. These findings can inform the design of support intervention research and enhance the relevance and supportiveness of services and programmes for recent refugees.  相似文献

This article examines how resilience of organizations can be enhanced by promoting their capability for adaptation. In a first step, the current understanding of the conceptualization of organizational resilience is compared to the resilience of individuals and teams. In a second step, the article also aims to illustrate the relationship between organizational resilience and organizational culture. Based on this, the applied research and development project “TeamSafe” in collaboration with a nuclear power plant is described as an example of a resilience-oriented training concept and a method for coping with unknown situations. In this project a multi-methodological approach (observational methods, video analysis and workshops) was chosen in order to identify relevant competencies and combine them with scientific findings. By involving simulator instructors and operating teams during the development process of the training concept, crucial action knowledge of operating teams in a nuclear power plant was gained by observations in the simulator and shared between different teams. This enabled the resilience-oriented development of the organization’s culture.  相似文献

Abstract

“Physical Dependence on Nicotine in Gum: A Placebo Substitution Trial,” JOHN R. HUGHES, et al. To test whether ex-smokers become physically dependent on nicotine in gum, we entered eight ex-smokers who were using nicotine gum into a randomized, double-blind, placebo-substitution trial. When placebo was substituted, seven of the eight subjects were observed to have withdrawal symptoms and two relapsed to smoking or nicotine gum. This result suggests that physical dependence (i.e., withdrawal) may be a cause of behavioral dependence on nicotine gum (i.e., use of gum beyond the recommended period) and physicians should emphasize the need for gradual reduction of nicotine gum.

“Absence of Therapeutic Benefit From Antacids or Cimetidine in Non-Ulcer Dyspepsia,” OLOF NYREN, et al. We randomly assigned 159 patients with non-ulcer dyspepsia, defined as chronic or recurrent epigastric pain without concomitant symptoms of the irritable bowel syndrome and with no evidence of organic disease, to treatment for three weeks with an antacid suspension one and three hours after meals, 400 mg of cimetidine twice a day, or placebo, according to a double-blind, double-dummy model. The intensity and duration of epigastric pain were recorded by the patients four times daily during a one-week period without therapy and during the three weeks of treatment. The mean reduction in pain intensity after three weeks in the placebo group was 25 percent. Neither antacid nor cimetidine treatment resulted in more than a 4 percent better effect. The reduction of pain was statistically significant (P < 0.01) in all three groups. The time course of the pain scores in the groups receiving active drugs followed closely those in the placebo group, and there were no significant differences between the groups at any stage of the treatment. We conclude that the neutralization or suppression of gastric acid is of no clinical value in patients with this syndrome. (New England Journal of Medicine 1986;314:339–43.)  相似文献

Abstract. Objective: “Drunkorexia,” limiting food intake before alcohol consumption, increases college students’ risk for negative alcohol-related health consequences. The current study tested whether (1) women engage in drunkorexia more frequently than men; (2) weight control motivations explain sex differences in drunkorexia; and (3) among women, weight control motivations are a particularly strong predictor of drunkorexia for heavier drinkers. Participants: Undergraduate males and females (N = 63) recruited during fall of 2011. Methods: Participants self-reported their alcohol consumption, drunkorexia, and weight control motivations online. Results: Findings supported hypotheses: weight control motivations explained why women engage in drunkorexia more than men; and the weight control motivation → drunkorexia relation was strongest for heavier- (vs lighter-) drinking women. Conclusion: Women have more weight concerns than men, which makes them more likely to engage in drunkorexia. Heavy-drinking women with strong weight control motivations are at greatest risk for drunkorexia. Interventions should help students more safely reconcile pressures to be thin and drink alcohol.  相似文献

This article reviews Nordic research, published from 1995 and onwards, on the relationship between unemployment and mental health among young adults. Cross‐sectional, longitudinal and time‐series studies are included. Cross‐sectional studies show that the unemployed experience more mental health problems than the non‐unemployed. Leaving unemployment is associated with increased well‐being. Economic problems, feelings of shame and poor social support increase the likelihood of psychological distress. The longitudinal studies show that unemployment increases the risk of psychological distress and attempted suicide, after initial mental health status and confounding factors are accounted for. The relationship remains significant when time‐invariant characteristics of the individuals are controlled for. The time‐series studies found no relationship between unemployment and suicide, but levels of psychological distress were found to vary with changes in the labour market. This relationship remained significant after excluding the non‐employed, indicating that unemployment trends have effects beyond those directly associated with unemployment.  相似文献

Same-sex parents are increasingly a topic of public discourse. A growing number of homosexuals openly speak about their desire to have children or are already living together in different family constellations. The current study examined the decisions for or against having children and the motivations behind those decisions among nonheterosexuals living in Germany. A sample of 1,283 nonheterosexuals participated by means of an online survey. As some nonheterosexual individuals do not identify themselves with a male or female gender identity, a third category, “gender different,” was generated. Motives for (not) having children, perceptions of social acceptance, experiences of discrimination in relation to one's sexual orientation, and levels of internalized stigma were taken into account regarding their influence on the decision about parenthood. Most respondents (80%) reported that they did not have children. However, among this group, 43% stated that they had decided to have children later in their lives, 24% were undecided, and 11% had already decided against having children. The most important influences on the decision of whether to have children were respondents’ age and their desire for emotional stabilization. Negative experiences as a result of sexual orientation and internalized stigma had no impact on the decisions regarding parenthood.  相似文献
