The significance and complexity of mostly male-dominated military peacekeeping forces continues to grow globally, as does the complexity of the masculinities performed in them. This article discusses the discourses and performances of peacekeeper masculinities, drawing on a qualitative case study of Finnish peacekeeping forces. The self-image of Finland as a provider of ideal peacekeepers and practising progressive gender policy is critically analysed. Taking the notion of multiple masculinities as a starting point, three indicative categories of Finnish peacekeeper masculinities are examined. Discourses of ‘amateur professionals’ and ‘peacekeeper fathers’ create space for military peacekeepers to show aspects of masculinity not associated with traditional military masculinities. The third discourse of ‘tough fighters’, however, harks back to more traditional ‘warrior’ concepts. Official gender mainstreaming efforts and assumptions that these attitudes are internalized ‘naturally’ by Finns are put into question by deprecatory or ambiguous attitudes towards gender equity and sexual exploitation. Despite being part of multi-national forces, peacekeeper masculinities are defined based on presumed notions of ‘national character’. 相似文献

This study examined (a) growth curves of youth participation in sports, performance and fine arts, and youth clubs throughout the high school years and (b) the associations between a series of predictors and the initial participation rates and growth over time. The predictors included individual, friend, and family factors. The moderating effect of youths' gender was also examined. Study participants were 272 youths (55% girls, Mage=12.4 years) and their parents. The predictors were assessed in Grade 6 and were based on reports by youths, parents, teachers, and classmates. Participation in organized activities was assessed annually from Grades 7 to 10. Altogether, the findings revealed that participation in sports, performance and fine arts, and youth clubs remains stable across the high school years. However, interindividual differences were found in the participation growth curves. This variation was predicted by individual, friend, and family factors, mostly with respect to sports activities. 相似文献

Objective: To determine whether completing a pre-enrollment Web-based alcohol brief motivational intervention (BMI) increased student retention and reduced student alcohol-related violations. Participants: Fall 2011 (3,364) and Fall 2012 (3,111) entering cohorts of all first-year students at a midwestern state university. Method: Students completing the brief intervention (BI) were compared to students not completing the BI. Retention was tracked for four years for the 2011 cohort and three years for the 2012 cohort. Campus and community alcohol violations were tracked for two academic years following enrollment. Kaplan–Meier survival analysis and Cox regression were used to test retention survival. Logistic regression was used to test campus and community violations. Results: Students in both cohorts who completed the BI had significantly higher retention and significantly fewer alcohol-related violations than noncompleters. Conclusions: Population-level Web-based BIs help prevent student dropout and decrease alcohol-related violations, with impacts extending multiple years. Web-based BI is an efficacious population-level prevention tool. 相似文献

This research note presents the first global population projections by educational attainment using methods of multi‐state population projection. The educational composition of the population by age and sex and educational fertility differentials are estimated for 13 world regions, and alternative scenarios are presented to the year 2030. One of these scenarios assumes constant educational transition rates and the other assumes that all regions reach Northern American levels of enrollment rates by 2030. The strong momentum or, as the case may be, inertia in the transformation of the educational composition of a population, seen in the results, arises because education is mostly acquired at a young age. The sex bias in the educational composition, especially evident in some developing countries, is unlikely to disappear soon. China has made remarkable progress in improving educational enrollment and as a consequence by 2030 is expected to have more educated people of working age than Europe and Northern America together. 相似文献

The authors examine the asymptotic behaviour of conditional threshold exceedance probabilities for an elliptically distributed pair (X, Y) of random variables. More precisely, they investigate the limiting behaviour of the conditional distribution of Y given that X becomes extreme. They show that this behaviour differs between regularly and rapidly varying tails. 相似文献

This study examined how men's masculine gender-role conflict and the importance men placed on interpersonal relationships in defining their self-identities predicted their relational health experiences in same-sex, dyadic friendships and community relationships. Using an Internet sample of 283 self-identified bisexual, gay, and straight men, results of hierarchical linear regression analyses indicated that for men across sexual orientations, the more importance men placed on interpersonal relationships with other men, the greater the degree of relational health they experienced in dyadic friendships. Additionally, for bisexual and gay men in dyadic friendships with other men, gender-role conflict was inversely related to the relational health of their friendships. In the domain of community relationships, the importance that bisexual and straight men placed on interpersonal relationships in defining their self-identities and levels of gender-role conflict predicted relational health experiences. For gay men, however, feelings of masculine gender-role conflict, alone, predicted poorer relational health in community relationships. Study limitations, clinical implications for practice, and future research directions are discussed. 相似文献

Regulatory impact analyses (RIAs), required for new major federal regulations, are often criticized for not incorporating epistemic uncertainties into their quantitative estimates of benefits and costs. “Integrated uncertainty analysis,” which relies on subjective judgments about epistemic uncertainty to quantitatively combine epistemic and statistical uncertainties, is often prescribed. This article identifies an additional source for subjective judgment regarding a key epistemic uncertainty in RIAs for National Ambient Air Quality Standards (NAAQS)—the regulator's degree of confidence in continuation of the relationship between pollutant concentration and health effects at varying concentration levels. An illustrative example is provided based on the 2013 decision on the NAAQS for fine particulate matter (PM2.5). It shows how the regulator's justification for setting that NAAQS was structured around the regulator's subjective confidence in the continuation of health risks at different concentration levels, and it illustrates how such expressions of uncertainty might be directly incorporated into the risk reduction calculations used in the rule's RIA. The resulting confidence-weighted quantitative risk estimates are found to be substantially different from those in the RIA for that rule. This approach for accounting for an important source of subjective uncertainty also offers the advantage of establishing consistency between the scientific assumptions underlying RIA risk and benefit estimates and the science-based judgments developed when deciding on the relevant standards for important air pollutants such as PM2.5. 相似文献
