There is little research on older persons with severe mental illness (SMI) who have experienced trauma. We conducted an exploratory study with 174 community mental health clients with SMI who were 50 years of age or older (range 50–87; mean age 58) to examine the relationship between subjective distress related to six common traumas and post-traumatic stress symptoms while controlling for gender and other key psychiatric symptoms. With regression analysis, we found that of the six common traumas, only distress from unexpected loss of a loved one was significant. That factor accounted for the most variance in post-traumatic stress symptoms than all other factors in the model including gender, psychiatric symptoms of SMI, and other trauma. Gender and symptoms of psychosis were also significant in the model. Unexpected losses, particularly in older persons with SMI, can cause considerable emotional distress and could be related to post-traumatic stress symptoms. Practitioners should be vigilant in regularly screening older people with SMI for recent loss of loved ones and be prepared to address their distress with grief/bereavement counseling.  相似文献

The recent series of very senseless shootings of both African American males and police officers are chilling visual demonstrations of the current degree of racial tension and social unrest in the United States. Stricter gun control laws are critically important but only part of the issue. Basic human and civil rights are at the heart of the issue. We must move toward a society in which individuals from varied backgrounds are valued, respected, and included. We must all accept the fact that we are all human beings and very much alike. This will require a national effort very similar to the Highway Beautification Act of 1965. We must adopt and implement policies that will specifically address multiple issues (discrimination, racism, marginalization, exclusion, implicit bias, and the lack of economic mobility) serving as drivers of our current social state. A key component should be increased investment in the educational system (starting in primary school) resulting in an increased college graduation rate and the development of curricula on race and racism and supporting cultural sensitivity and implicit bias training from kindergarten through professional schools.  相似文献

ABSTRACT

In response to the growing importance of online education in social work education, this article describes the context of online teaching and learning in social work education. Online teaching and learning are further discussed in the context of historically Black colleges and universities (HBCUs). We emphasize the importance and need for trained faculty to teach in an online environment, particularly in HBCUs; offer an example of how the University of the District of Columbia, an HBCU, prepares its faculty to teach online; and conclude with specific strategies for online teaching and social work faculty. Finally, we provide recommendations for social work education.  相似文献

ABSTRACT

This article investigates how Swedish gay men pursue and understand fatherhood, using a qualitative, semi-structured methodological approach. We are interested in how practical issues and different fatherhood arrangements are understood and handled by the fathers; how the construction of “rainbow families” is understood in relation to legal issues; parental responsibilities; and thoughts regarding gender-equal and gender-neutral relationships within Swedish society and culture. The results show that the trajectory of gay men toward fatherhood is shaped by a variety of mediating factors such as interactions with agencies, clinics, attorneys, and the state. There are some significant legal, social, financial, and cultural obstacles to realizing gay parenthood. There are also cases where study participants talked about a sense of intolerance expressed toward gay parents within a gay community. Although there are still strong normative dimensions involved in the construction of modern parenthood, the grip of heteronormative views on family life and sexuality is changing; the narratives presented also represent a questioning of the hegemonic image of fatherhood in Sweden. Consequently, it is possible to discern different attempts at transgressing and changing the cultural landscape of fatherhood and the ways people build families today.  相似文献

It has long been asserted that in univariate location-scale models, when concerned with inference for either the location or scale parameter, the use of the inverse of the scale parameter as a Bayesian prior yields posterior credible sets that have exactly the correct frequentist confidence set interpretation. This claim dates to at least Peers, and has subsequently been noted by various authors, with varying degrees of justification. We present a simple, direct demonstration of the exact matching property of the posterior credible sets derived under use of this prior in the univariate location-scale model. This is done by establishing an equivalence between the conditional frequentist and posterior densities of the pivotal quantities on which conditional frequentist inferences are based.  相似文献

In this paper, we establish the role of concomitants of order statistics in the unique identification of the parent bivariate distribution. From the results developed, we have illustrated by examples the process of determination of the parent bivariate distribution using a marginal pdf and the pdf of either of the concomitant of largest or smallest order statistic on the other variable. An application of the results derived in modeling of a bivariate distribution for data sets drawn from a population as well is discussed.  相似文献

Mixture distributions have become a very flexible and common class of distributions, used in many different applications, but hardly any literature can be found on tests for assessing their goodness of fit. We propose two types of smooth tests of goodness of fit for mixture distributions. The first test is a genuine smooth test, and the second test makes explicit use of the mixture structure. In a simulation study the tests are compared to some traditional goodness of fit tests that, however, are not customised for mixture distributions. The first smooth test has overall good power and generally outperforms the other tests. The second smooth test is particularly suitable for assessing the fit of each component distribution separately. The tests are applicable to both continuous and discrete distributions and they are illustrated on three medical data sets.  相似文献

We consider returns to scale in food preparation as a potential resolution of a puzzle raised by Deaton and Paxson (Journal of Political Economy, 106(5), 897–930, 1998). We clarify the conditions under which returns to scale in food preparation can resolve the puzzle. The key requirement is that foods are heterogeneous in time costs. We then show that detailed food expenditure and time use data are consistent with larger households shifting to more time intensive foods.  相似文献
