Abstract

After a needs assessment indicated that male students underutilized campus health services, the San Francisco State University Student Health Service developed a coordinated complement of outpatient health services for men. The authors review their experience in developing, implementing, operating, and evaluating this ongoing clinical service. The needs assessment and subsequent program evaluation data suggest that male students on a large, culturally diverse, urban campus would respond favorably to targeted, multidisciplinary health initiatives that incorporate the principles of health promotion and disease prevention.  相似文献

This article examines the effect of television on the length of legislative sessions at the federal level in the United States. Data from the U.S. Congress during the period 1972–96 are employed, during part of which time each house of Congress received significant television coverage by C-SPAN and C-SPAN2. Evidence from a Parks regression suggests that the presence of C-SPAN has increased House sessions by 88–250 hours and the presence of C-SPAN2 has increased Senate sessions by a striking 252–431 hours, other things constant. Additional estimates suggest that House sessions are about two minutes longer per bill introduced under the eye of C-SPAN, and Senate sessions are about four minutes longer per bill introduced in the presence of C-SPAN2. Longer sessions, which represent low-cost forms of advertising for incumbents, are not without costs to taxpayers. We estimate that these costs lie somewhere between $16 million and $392 million in real terms per session of Congress.  相似文献

Abstract

O-Pipon-Na-Piwin Cree Nation (OPCN), an Indigenous community in northern Manitoba, Canada, was flooded and forced to relocate from ancestral lands to a nearby settlement under such circumstances. Regaining strength from their inherent cultural values grounded in their relationship with the land, OPCN eventually formed a community-based food program called Ithinto Mechisowin (IMP) (‘food from the land’). This article uses OPCN's concept of resource (wechihituwin) and decolonization (pasekonekewin) to present a nuanced understanding of Indigenous food systems in Canada. We argue that the ways in which IMP inspires reconnection with land, thereby improving access to culturally appropriate healthy food, are steps forward in strengthening Indigenous food sovereignty.  相似文献

Fish living around the coral reefs in the Philippines provide livelihoods for more than a million local fishers and are an important source of protein for coastal communities. However, this rich resource is at risk from myriad threats, which consequently threaten human livelihoods, nutrition, and health. In this paper, we examine the degree to which marine protected areas (MPAs), which aim to conserve marine biodiversity, are associated with improved nutritional outcomes in children under age 5. This analysis, which uses data from the 2008 Philippines Demographic and Health Survey and MPA data from the Coastal Conservation and Education Fund, found a positive association between MPAs and children’s dietary diversity when the MPAs were located closer than 2 km to a child’s community. MPA characteristics such as age or type of management were not consistently associated with dietary diversity. These results suggest a positive association of proximity to MPAs with certain aspects of children’s diet.  相似文献

In this paper, we intend to deconstruct the term ‘tribalism’ as a colonial category, which figures as a prominent concept in social studies on Kurds as well as the Middle East at large. Blithely used, tribalism has occupied a central place, especially in the existing scholarship on Kurdistan. Some earlier anthropological works have gone so far as to regard tribalism as the ‘DNA’ of Middle Eastern people. Drawing on recent studies on Latin America, Africa and Central Asia, we argue that the use of tribalism as if it is the natural constitution of Kurdish society has caused a significant misrepresentation and oversimplification of socio‐political life in Kurdistan as well as the broader Middle East. In a way, the existing body of scholarship on this region has reproduced statist‐nationalist discourses at the expense of dominated communities (e.g., Kurds). The historical context of both colonial powers and nation‐states ‘combating tribes and tribalism’ coincided with the emergence of the discourse of racial biopolitics. Thus, the use of the term tribalism to define certain nations or ethnic groups should not be viewed as merely an application of socio‐anthropological categories. Hence, we argue that the ethical aspects and implications of the use of tribalism by both colonial powers and later by nation‐states to define certain ethnic groups must not be overlooked.  相似文献

In this paper, we consider Marshall–Olkin extended exponential (MOEE) distribution which is capable of modelling various shapes of failure rates and aging criteria. The purpose of this paper is three fold. First, we derive the maximum likelihood estimators of the unknown parameters and the observed the Fisher information matrix from progressively type-II censored data. Next, the Bayes estimates are evaluated by applying Lindley’s approximation method and Markov Chain Monte Carlo method under the squared error loss function. We have performed a simulation study in order to compare the proposed Bayes estimators with the maximum likelihood estimators. We also compute 95% asymptotic confidence interval and symmetric credible interval along with the coverage probability. Third, we consider one-sample and two-sample prediction problems based on the observed sample and provide appropriate predictive intervals under classical as well as Bayesian framework. Finally, we analyse a real data set to illustrate the results derived.  相似文献

In this paper, we discuss a progressively censored inverted exponentiated Rayleigh distribution. Estimation of unknown parameters is considered under progressive censoring using maximum likelihood and Bayesian approaches. Bayes estimators of unknown parameters are derived with respect to different symmetric and asymmetric loss functions using gamma prior distributions. An importance sampling procedure is taken into consideration for deriving these estimates. Further highest posterior density intervals for unknown parameters are constructed and for comparison purposes bootstrap intervals are also obtained. Prediction of future observations is studied in one- and two-sample situations from classical and Bayesian viewpoint. We further establish optimum censoring schemes using Bayesian approach. Finally, we conduct a simulation study to compare the performance of proposed methods and analyse two real data sets for illustration purposes.  相似文献

To tackle sustainability, firms often use partnerships with organizations from different industries or societal sectors such as government and civil society. While partnerships show potential for firms to improve their sustainability performance, they not only lead to a potential to learn from diversity but also to tensions due to a lack of unity between partners. In partnerships for sustainability, this unity-diversity tension particularly manifests itself in different views of sustainability. This paper examines how this tension affects the sustainability performance of firms taking part in partnerships for sustainability in developing countries. To address this question, this tension is conceptualized as being the result of differences in organizational frames and institutional logics between a focal firm and other organizations in the partnership. It is also taken into consideration that firms are embedded in an overarching, relational network structure that allows them to manage the diversity in frames and logics. To test the hypotheses, the study analyses 1353 greenhouse gas emission reduction projects of 322 firms from developing countries active in the carbon-offset market from 2007 to 2009. The findings show that if partners hold different frames and belong to different sectors, a firm's sustainability performance improves first due to learning from diversity but after a turning point decreases from a lack of unity. This inverse U-shape relationship is flipped if a firm occupies a brokerage position in its network.  相似文献
