A new two-parameter distribution, the gamma-Maxwell distribution, isproposed and studied. We generate the new distribution using the gamma-G generator of distributions. The proposal distribution can be seen as an extension of the Maxwell distribution with more flexibility in terms of the distribution asymmetry and kurtosis. We study some probability properties, discuss maximum-likelihood estimation and present a real data application indicating that the new distribution can improve the ordinary Maxwell distribution in fitting real data. 相似文献

We derive an empirical poverty index containing most of those proposed in the literature. Then, we study its asymptotic behavior by using empirical processes theory. From the results obtained, we derive a Wald-type test for comparing a vector of theoretical poverty indices to a vector of reference indices. We study the test statistic under the null hypothesis of equality, fixed alternatives, and a sequence of local alternatives. A simulation experiment conducted shows that our test performs well for exponential and Pareto data. 相似文献

This qualitative study focuses on the different ways time is experienced by children in families who face time challenges because of a family member's job that required work travel. Data are from a family‐level study that includes interviews of all family members older than age 7. Using grounded theory methodology, this study illustrates the ways in which job demands and family processes interact. The analysis centers on 75 children's perspectives from 43 families. Holding together assessments of having enough time while wanting more time with their parents, children express emotion, generally unrecognized by parents, around the topic of family time. Children's experience of time with parents is rushed or calm, depending on the activities done in time and the gender of the parent with whom they spend time. Findings are interpreted through a feminist social constructionist lens. 相似文献

Bisexual youth are at elevated risk for depression when compared with lesbians and gay men. Research on bisexual stigma suggests that these youth are uniquely vulnerable to stress related to sexual identity disclosure. Depression associated with this stress may be buffered by social support from parents and friends. We examined the differential influence of social support from parents and friends (Child and Adolescent Social Support Scale) on the relation between disclosure stress (LGBTQ Coming Out Stress Scale) and depressive symptoms (Beck Depression Inventory) and differences by gender in a sample of cisgender bisexual youth (N = 383) using structural equation modeling. Parental support buffered the association between stressful disclosure to family and depressive symptoms, especially for bisexual men; bisexual women seemed not to benefit from such support when disclosure stress was high. This nuanced examination elucidates the ways family members and clinicians can best support bisexual youth sexual identity disclosure. 相似文献

Sexual harassment on college campuses is a frequent occurrence and serious public health concern. Victims of sexual harassment are at risk for many possible negative health consequences. In addition, certain psychological distress symptoms and/or alcohol use may put individuals at increased risk of being victims of sexual harassment. Data from more than 2,000 college students in the Midwestern United States were used to examine reciprocal causal effects of the relations between (a) experiencing sexual harassment and alcohol use and (b) experiencing sexual harassment and psychological distress symptoms, specifically depression and anger/hostility. Analyses were conducted separately for sexual harassment which occurs at school and which occurs in college students’ workplaces, and also separately for men and women. Results of cross-lagged panel models showed that there were reciprocal causal effects between sexual harassment and alcohol problems, depression, and anger. Discussion focuses on the overall patterns of results as well as the nuances within these findings. 相似文献

Does Viewing Pornography Diminish Religiosity Over Time? Evidence From Two-Wave Panel Data 总被引:1,自引:1,他引:0

Research consistently shows a negative association between religiosity and viewing pornography. While scholars typically assume that greater religiosity leads to less frequent pornography use, none have empirically examined whether the reverse could be true: that greater pornography use may lead to lower levels of religiosity over time. I tested for this possibility using two waves of the nationally representative Portraits of American Life Study (PALS). Persons who viewed pornography at all at Wave 1 reported more religious doubt, lower religious salience, and lower prayer frequency at Wave 2 compared to those who never viewed porn. Considering the effect of porn-viewing frequency, viewing porn more often at Wave 1 corresponded to increases in religious doubt and declining religious salience at Wave 2. However, the effect of earlier pornography use on later religious service attendance and prayer was curvilinear: Religious service attendance and prayer decline to a point and then increase at higher levels of pornography viewing. Testing for interactions revealed that all effects appear to hold regardless of gender. Findings suggest that viewing pornography may lead to declines in some dimensions of religiosity but at more extreme levels may actually stimulate, or at least be conducive to, greater religiosity along other dimensions. 相似文献

Researchers have found that when young people participate in discussions of controversial political issues, they often become more politically engaged and informed (Hess, 2009). Nonetheless, some educators avoid fostering such discussions because they can become heated and distract from academic learning (Hess, 2002). Presidential elections, including the highly publicized debates, provide substantial material for discussions of major national and international issues, but no published research has examined how educators can leverage these events to generate productive civic learning experiences. In this article, we analyze data collected in seven high school classrooms during the 2012 presidential election to examine the challenges and opportunities associated with generating substantive, dynamic discussions of presidential debates. Our findings indicate that students enjoyed learning about candidates' different perspectives and that certain strategies were especially helpful for fostering substantive discussions: (a) scaffolding students' preparation for discussion; (b) providing opportunities for students to address open-ended questions; (c) redirecting students' engagement in competitive, interpersonal dynamics to learning about public issues; and (d) countering students' partisan tendencies. We discuss implications for practice and research and present a conceptual framework for generating dynamic, substantive democratic discussions. 相似文献

Contemporary global issues can be examined through the lens of modern photographic art. In an effort to prepare global-ready graduates, this article explores the pressing problems of environmental degradation, urbanization, and homelessness through the work of three contemporary artists. Illustrative works, suggested approaches, and curriculum resources are provided. 相似文献

In this interpretive case study the researchers examined the beliefs of 13 self-identifying race-conscious secondary social studies teachers from diverse racial or ethnic, gender, and school-context backgrounds. The researchers found that the teachers' beliefs and views of practice were generally aligned with the main assertions of critical race theory. The teachers described their personal and professional experiences as a major influence on their race-conscious beliefs and views of practice. Moreover, teachers in diverse contexts described having to learn how to navigate the different racial experiences of the students in their classrooms, while teachers in racially segregated contexts (predominately White, Black, or Latino) emphasized the importance of teaching their students about others. Finally, despite the teachers' regular integration of race-related issues into their required and elective courses, they expressed a desire to have more opportunities to teach about race. 相似文献
