Increasingly, bills and policies prohibit the participation of trans women in competitive sport. The current sociopolitical moment begs the following question: how do interpersonal interactional moments function alongside formal policies and rules to shape trans athletes’ experiences of belonging in sport? Although formal institutional rules govern trans athletes’ ability to compete in sport, informal social sanctioning also denies these athletes equitable, or even de facto, membership in sport. I draw upon two case studies to explore trans athletes’ experiences of membership in elite “women's” sport. I apply Evelyn Nakano Glenn's work on citizenship to consider how trans athletes’ experiences of belonging are influenced by both formal rules imposed by organizations as well as informal social interactions with members of their sporting communities. Inclusion is not synonymous with membership. Trans athletes render visible the ways in which this system functions to contain the diversity of humanity's gender expression. 相似文献

Recent occupational injury data shows a rising trend, which happens to coincide with both increases in the foreign-born population
in the U.S. and changes in its composition. This study aims to explore the presence of a statistical relationship between
occupational injuries and the level of English proficiency of foreign-born using cross-sectional data on the rate of injury
and count of injury incidents. A cultural gap hypothesis is also examined as an alternative explanation for the rise in work
injuries. While there is some support for the adverse effect of inadequate English language proficiency of foreign-born, the
results for the cultural gap hypothesis are more robust. 相似文献

In this work we derive closed form expressions for the probability density functions and moments of the quotient and product of the components of the bivariate generalized exponential distribution introduced by Kundu and Gupta (J Multivariate Anal, 100:581–593, 2009) and compute the percentage points. The derivations will be useful for practitioners of this bivariate model. We then give a real data application of the product. 相似文献

Over the last few decades several countries have turned to inflation targeting as a policy choice for instilling stability into their economies. Prior studies have shown that inflation targeting has reduced inflation in those countries without significantly impacting GDP. This study seeks to improve upon these results by identifying the impact of timing on the policy decision as well as its impact as related to specific regions of the world. The focus is on developing countries across six regions. We find significant regional variation in developing countries in our sample in terms of the direction of changes in inflation following a switch to the inflation targeting policy. Moreover, although the impact of inflation targeting on real GDP is minimal overall, there is a statistically significant increase in real GDP among developing countries in certain regions only, namely, Europe, Latin America, and the Middle East. 相似文献

Process capability (PC) indices measure the ability of a process of interest to meet the desired specifications under certain restrictions. There are a variety of capability indices available in literature for different interest variables such as weights, lengths, thickness, and the life time of items among many others. The goal of this article is to study the generalized capability indices from the Bayesian view point under different symmetric and asymmetric loss functions for the simple and mixture of generalized lifetime models. For our study purposes, we have covered a simple and two component mixture of Maxwell distribution as a special case of the generalized class of models. A comparative discussion of the PC with the mixture models under Laplace and inverse Rayleigh are also included. Bayesian point estimation of maintenance performance of the system is also part of the study (considering the Maxwell failure lifetime model and the repair time model). A real-life example is also included to illustrate the procedural details of the proposed method. 相似文献

Many procedures exist for testing equality of means or medians to compare several independent distributions. However, the mean or median do not determine the entire distribution. In this article, we propose a new small-sample modification of the likelihood ratio test for testing the equality of the quantiles of several normal distributions. The merits of the proposed test are numerically compared with the existing tests—a generalized p-value method and likelihood ratio test—with respect to their sizes and powers. The simulation results demonstrate that proposed method is satisfactory; its actual size is very close to the nominal level. We illustrate these approaches using two real examples. 相似文献

A Bayesian elastic net approach is presented for variable selection and coefficient estimation in linear regression models. A simple Gibbs sampling algorithm was developed for posterior inference using a location-scale mixture representation of the Bayesian elastic net prior for the regression coefficients. The penalty parameters are chosen through an empirical method that maximizes the data marginal likelihood. Both simulated and real data examples show that the proposed method performs well in comparison to the other approaches. 相似文献

Moderators of the Relationship Between Physical Activity and Alcohol Consumption in College Students

Abstract Objective: Among college students, several studies have found a positive relationship between physical activity and alcohol use. The current study tested gender, Greek status, and ethnicity as potential moderators of the physical activity-alcohol use relationship. Participants: Participants were college freshmen (n = 310) endorsing alcohol/drug use. Methods: Students completed questionnaires assessing a number of health behaviors. Results: Results indicated that gender and Greek status were significant moderators of the relationship between physical activity and alcohol consumption. There was a positive relationship between physical activity and alcohol use for men and Greeks, but not for females and non-Greeks. Conclusions: These findings suggest that exercise does not serve as a protective factor for any of the subgroups of college students studied and is positively associated with drinking among college students who are men and/or involved with the Greek system. 相似文献

Major sociospatial transformation processes are taking place, and so concepts such as tradition, distinctiveness, and identity have become fundamental but delicate factors in the context of the social environment. Consequently, identity has become not only a term, but rather a comprehensive theme and concept, in making new places and built environments. In this context of argument, this article elucidates the implication of identity at different scales. It emphasizes the importance and hybridity of urban identities and how they may become entities or even mechanisms to overcome globalization issues. This article looks at global examples to exemplify various manifestations of urban identities. This theoretical article aspires to promote debates that can benefit current research programs in the context of globalization, urban identity, and sociocultural diversity. Finally, the aim here for specifying different levels of urban identities is not necessarily toward categorizing them, but rather to identify their roles and propositions in various scales that are related to humans and their social environments. 相似文献
