The role of social work in the ICU: reducing family distress and facilitating end-of-life decision-making

The costs associated with Intensive Care Units (ICUs) are high and at times invasive ICU care may not be beneficial, particularly for those patients admitted to ICUs who have little hope of recovery. The process of clarifying medical goals for these patients is often facilitated by addressing psychosocial factors. Social workers in the ICU are uniquely qualified to assess and address many of the complex psychosocial circumstances and can clarify potential misperceptions, enhancing communication among patients (if capacitated), their families, and the medical team members. This can not only help improve quality of life for very sick and dying patients in the ICU and their families, but may also reduce the likelihood of decision-making conflicts from arising. Further studies need to be done to investigate the effectiveness of social work interventions in reducing family distress, avoiding care that is unwanted by patients, and demonstrating cost-saving benefits.     

A Survey of the Teaching of Statistics in M.B.A. Programs

A survey of business schools was conducted to obtain information about the current state of the teaching of business statistics to students enrolled in M.B.A. degree programs. The survey was undertaken for and presented at a June 1986 conference on “Making Statistics More Effective in Schools of Business,” held at the University of Chicago's Graduate School of Business. Information was elicited concerning both the required statistics sequence and elective statistics courses for M.B.A. students, as well as computer usage in these courses. This article summarizes the information obtained from the survey.     

An exploration of social & emotional factors impacting well-being in women who have sex with women (WSW)

Abstract

“Women who have sex with women” or WSW have unique perspectives within the LBGTQ spectrum. The purpose of this study included documenting perceptions, feelings, and experiences among WSW. Thirty-seven women participated in six focus groups, ages ranged from 20–64 years. Responses were transcribed and thematically coded. Four themes emerged as influencing factors: shame and fear, community, gender roles, and normalcy. Each major theme produced minor themes providing a context within major themes. Results offer valuable insights that can assist community members, health professionals, and scientists to better appraise the disparities and stigma impacting social and emotional well-being among WSW.     

Children forever: The search for origins among Chilean adults who were adopted

There has been a global increase in the number of adults who were adopted 1 1 To make the text more readable, we use the term “adult adoptee” rather than our preferred term “people who were adopted.” We prefer the latter term because it does captures our understanding that adoption is a practice and a life experience and not necessarily a permanent fixture of the identities of people who were adopted.
searching for their origins. This trend has promoted the interest of social sciences researchers, as well as carry out the obligations of states to provide specialized services. In this article, we present some results from the first qualitative study that explores the experiences of some Chilean adults who were adopted and searched for their origins in Chile through the National Service of Minor's Search for Origins Program. The narratives of the participants show that, in spite of legislative changes, a series of barriers and contradictions continue to exist, which make it difficult to guarantee the right to know one's origins. The legal and technical frameworks and practices analysed show how difficult it is to dismantle the “clean break” principle. They also highlight the persistence of the image of adoptees as “minors” who need the “protection” of their parents or professionals. We discuss the different challenges to be considered by researchers, practitioners, and policy‐makers involved in adoption policies and practices.     

Juggling and Dealing: The Creative Work of Care Package Purchasing

In conventional diagrams of the new service delivery process, assessment of need is linked to purchase by a single line or arrow; the implication is that purchase follows more or less logically and directly from assessment. This paper focuses on the complex creative work that goes on in the "space" between assessment of need and purchase of service, and the changing influences on that work. "Purchase" is deconstructed to reveal the complex processes and calculations involved, and the ways in which budgets "free" resources and markets influence the final outcome. The paper describes the effects on care package construction and purchase of changing policies, budget arrangements and financial limits; it goes on to outline the difficulties and complications in using information on unit costs in purchasing. Unit costs are only part of a complex equation in which prices are negotiated and total cost juggled in the context of budgets, financial limits, real accessibility and balanced by quality considerations. It is suggested that talk of "playing shops" and use of "off-the-shelf" services underestimates the complexity of care package construction and purchase. Micro-purchase of care services has more in common with dealing and juggling than with lifting standardized, packaged, pre-priced goods off shelves in Sainsbury's.     

GENDER AND HEGEMONY IN FASHION MAGAZINES:

Women's responses in the context of focus groups to fashion photographs and clothing advertisements in Vogue magazine and to a brief questionnaire eliciting their attitudes toward clothing and fashion are used to examine the nature and extent of hegemonic influences in fashion. Participants' sources of information about fashion suggest that the authority of the fashion press is limited. The magazine's conceptions of women's roles as expressed in its fashion photography fit a model of "conflicted" hegemony characteristic of American media and popular culture in general. Empowered by the cultural context of conflicted hegemony, women were generally critical of fashion photographs. Their responses to photographs were influenced by their acceptance of traditional norms of feminine demeanor but varied by age and race. They rejected the magazine's orientation toward the use of fashionable clothing for postmodernist roleplaying in favor of a modernist outlook.     

Did Australia’s Baby Bonus Increase Fertility Intentions and Births?

In May 2004, the Australian government announced a “Baby Bonus” policy, paying women an initial A$3,000 per new child. We use household panel data from the Household, Income and Labour Dynamics in Australia Survey (N = 14,932) and a simultaneous equations approach to analyze the effects of this bonus on fertility intentions and ultimately births. The results indicate that opportunity costs influence intentions and births in predictable ways. Fertility intentions rose after the announcement of the Baby Bonus, and the birth rate is estimated to have risen modestly as a result. The marginal cost to the government for an additional birth is estimated to be at least A$3,000 per new child. We use household panel data from the Household, Income and Labour Dynamics in Australia Survey (N = 14,932) and a simultaneous equations approach to analyze the effects of this bonus on fertility intentions and ultimately births. The results indicate that opportunity costs influence intentions and births in predictable ways. Fertility intentions rose after the announcement of the Baby Bonus, and the birth rate is estimated to have risen modestly as a result. The marginal cost to the government for an additional birth is estimated to be at least A126,000.     

Dating and friendships in adolescence: Variation across same-sex and other-sex romantic partners

This research examined associations between dating and number of friends for rural adolescents with same-sex and other-sex dating partners using longitudinal sociometric data (N = 2826; 55% female, 87% White, mean age = 14 at baseline). In multilevel models assessing within-person change, boys gained female friends when they were in same-sex romantic relationships, compared to when they were single. In contrast, girls in same-sex relationships lost female friends and gained male friends. Adolescents in other-sex romantic relationships gained same-sex friends compared to when they were single. Results advance understanding of adolescent social and sexual development, suggesting that sexual minority adolescents find allies when dating but may struggle to maintain same-sex friendships.
