Work and breastfeeding decisions are jointly determined for higher socioeconomic status US mothers

We study postpartum decisions about paid work and breastfeeding using a simultaneous equations model. For our sample of higher socioeconomic status mothers, we find a joint decision process for three sets of decisions modeled: work leave duration and duration of any, as well as of exclusive, breastfeeding, and daily work hours and daily breastfeedings at infant age 3 months. We find that returning to paid work 1 week earlier reduces any breastfeeding duration by about two-thirds of a week while extending breastfeeding by a week delays work participation by about one-third of a week. We find larger elasticities for decisions involving daily work hours and number of breastfeedings at 3 months than for work leave duration and any breastfeeding duration and the smallest elasticities for duration of exclusive breastfeeding and work leave. This marks the first study to find a joint decision-making process for postpartum work and breastfeeding decisions and suggests that, in addition to increased leave impacting breastfeeding behaviors, successful breastfeeding promotion policies can have nontrivial impacts on the US labor market.

The potential impact of discrimination fears of older gays, lesbians, bisexuals and transgender individuals living in small- to moderate-sized cities on long-term health care

As an exploration of the potential impact of fears of discrimination against GLBTs in long-term health care settings, this study compared perceptions of GLBT persons and heterosexuals. A total of 132 GLBT persons and 187 heterosexuals living in Eastern Washington completed a survey that contained demographic questions and perceptions of discrimination in long-term care settings. Most respondents suspected that staff and residents of care facilities discriminate against GLBTs. GLBT respondents who believed that residents of care facilities are victims of discrimination were more likely to believe that they would have to hide their sexual orientation if admitted to a care facility. GLBT respondents were more likely than heterosexual respondents to believe that GLBTs do not have equal access to health care and social services, that GLBTs residents of care facilities are victims of discrimination, that GLBT sensitivity training programs would benefit staff and residents of care facilities, and that GLBT retirement facilities would be a positive development for older GLBTs. This study is offered as a preliminary investigation of concerns about GLBT discrimination in health care settings, how concerns are expressed, and the implications of those concerns for health care needs.     

Recovering from severe mental illness: mutual influences of self and illness

A growing body of literature on the subjective experiences of people with severe mental illness (SMI) reveals the importance of the experience of self. The current study explored how the course of SMI is related to individuals' subjective experience of self. Bimonthly, comprehensive, semi-structured interviews with 43 people who had been discharged from psychiatric hospitalization were conducted over a 1-year period. Qualitative analysis of the data revealed mutual influences between the experience of self and illness over time. Conceptual and clinical implications of the relation between self and illness are discussed.     

Experimental partnering: interpreting improvisatory habits in the research field

This paper proposes that established research techniques can be developed in new directions by becoming attentive to the ways in which novel epistemological and ontological frameworks can shape the production of research knowledges. Drawing upon ideas from performance theory and science studies, and two brief fieldwork examples – archival research on the MRC’s Common Cold Unit and participant observation of the challenge of moving a herd of cattle – we argue that habits are also always to extent improvised; shaped by the capacities of human bodies to sense and respond to the nonhuman agentive world around them, including methodological habits. We propose a new term, ‘experimental partnering’ to define an interpretative approach that is attentive to how practice can illuminate the improvisatory or unstable temporary alignments that underlie some habits. ‘Experimental partnering’ is not offering a new way to access the research field, but a term to express a particular interpretative mode that draws attention to human-nonhuman relations and assemblages, fostering new apprehensions of how these more than social relations modify and interrupt the habitual.     

Simulating alternative foodgrain price and trade policies: An application for the Dominican Republic

Self-sufficiency and free trade are two of the most frequently advocated foodgrain policies. This paper presents a methodology for simulating the impact of thse two policy alternatives on a country's production, consumption, farm price, retail price and trade of a staple foodgrain. Simple formulas are also derived for estimating the effect of different policies on consumer and producer welfare. A simulation of the two policy alternatives is conducted for the case of rice in the Dominican Republic.     

Children's Influence on Internet Access at Home: Adoption and use in the family context

In this study, an integrated quantitative and qualitative research design was employed. From over 900 telephone interviews a typology of family types based on possession of media appliances was constructed, then divided into 'traditional' (low media density), 'intermediate' (average media density) and 'multimedia' (high media density) families. This typology was then used as a basis for selecting thirty-eight families for in-depth interviews. Of these, thirty-one contained children and it is these that form the basis for this article. The results of the family interviews indicate that children are a very important factor in the acquisition and use of the Internet. It was apparent from our interviews that Internet access and use become major issues in family discussions and conflicts - both between parents and children and between siblings.     

Lord of the Guys: Alpha Girls and the Post-feminist Landscape of American Education

A recent discourse of girlhood, that of alpha girl and empowerment, has emerged in US popular literature with claims that adolescent girls are uniquely positioned to become the new economic, cultural and social winners of the twenty-first century. Similar to Sheryl Sandberg’s story in Lean In, Alpha girls embody both traditional masculine characteristics, such as competitiveness and independence, with traditional features of femininity such as collaboration, according to psychologist Dan Kindlon, author of Alpha Girls: Understanding the New American Girl and How She is Changing the World. However, little research has been conducted that explores the alpha girl discourse in the day-to-day lives of adolescent girls, deemed alpha, in US public school classrooms. Using interview and observation data, this paper examines how Kindlon’s supposed alpha girls and their middle school teacher make sense of and live this notion of empowerment, and argues that their experiences both complicate and reify the alpha girl discourse.     

Choice of Baselines in Clinical Trials: A Simulation Study from Statistical Power Perspective

Multiple assessments of an efficacy variable are often conducted prior to the initiation of randomized treatments in clinical trials as baseline information. Two goals are investigated in this article, where the first goal is to investigate the choice of these baselines in the analysis of covariance (ANCOVA) to increase the statistical power, and the second to investigate the magnitude of power loss when a continuous efficacy variable is dichotomized to categorical variable as commonly reported the biomedical literature. A statistical power analysis is developed with extensive simulations based on data from clinical trials in study participants with end stage renal disease (ESRD). It is found that the baseline choices primarily depend on the correlations among the baselines and the efficacy variable, with substantial gains for correlations greater than 0.6 and negligible for less than 0.2. Continuous efficacy variables always give higher statistical power in the ANCOVA modeling and dichotomizing the efficacy variable generally decreases the statistical power by 25%, which is an important practicum in designing clinical trials for study sample size and realistically budget. These findings can be easily applied in and extended to other clinical trials with similar design.
