Biodemographic modeling of the links between fertility motivation and fertility outcomes in the NLSY79

In spite of long-held beliefs that traits related to reproductive success tend to become fixed by evolution with little or no genetic variation, there is now considerable evidence that the natural variation of fertility within populations is genetically influenced and that a portion of that influence is related to the motivational precursors to fertility. We conduct a two-stage analysis to examine these inferences in a time-ordered multivariate context. First, using data from the National Longitudinal Survey of Youth, 1979, and LISREL analysis, we develop a structural equation model in which five hypothesized motivational precursors to fertility, measured in 1979–1982, predict both a child-timing and a child-number outcome, measured in 2002. Second, having chosen two time-ordered sequences of six variables from the SEM to represent our phenotypic models, we use Mx to conduct both univariate and multivariate behavioral genetic analyses with the selected variables. Our results indicate that one or more genes acting within a gene network have additive effects that operate through child-number desires to affect both the timing of the next child born and the final number of children born, that one or more genes acting through a separate network may have additive effects operating through gender role attitudes to produce downstream effects on the two fertility outcomes, and that no genetic variance is associated with either child-timing intentions or educational intentions.     

One love: explicit monogamy agreements among heterosexual young adult couples at increased risk of sexually transmitted infections

HIV prevention strategies among couples include condom use, mutual monogamy, and HIV testing. Research suggests that condom use is more likely with new or casual partners, and tends to decline as relationships become steady over time. Little is known, however, about explicit mutual monogamy agreements and HIV testing within heterosexual couples. This study used data from 434 young heterosexual couples at increased risk of HIV and sexually transmitted infections (STIs) to assess (a) couple concordance on perceptions of a monogamy agreement, sustained monogamy, and HIV testing; and (b) the associations of relationship and demographic factors with monogamy agreement, sustained monogamy, and HIV testing. Results indicated only slight to fair agreement within couples on measures of monogamy agreement and sustained monogamy. Overall, 227 couples (52%) concurred that they had an explicit agreement to be monogamous; of those, 162 (71%) had sustained the agreement. Couples with greater health protective communication and commitment were more likely to have a monogamy agreement. Couples of Latino and Hispanic ethnicity and those with children were less likely to have a monogamy agreement. Only commitment was related to sustained monogamy. Having children, greater health protective communication, and perceived vulnerability to HIV and STIs were associated with HIV testing within the couple.     

Factors in Exposure Assessment: Ethnic and Socioeconomic Differences in Fishing and Consumption of Fish Caught along the Savannah River

South Carolina has issued fish consumption advisories for the Savannah River based on mercury and radionuclide levels. We examine differences in fishing rates and fish consumption of 258 people interviewed while fishing along the Savannah River, as a function of age, education, ethnicity, employment history, and income, and test the assumption that the average consumption of fish is less than the recreational value of 19 kg/year assumed by risk assessors. Ethnicity and education contributed significantly to explaining variations in number of fish meals per month, serving size, and total quantity of fish consumed per year. Blacks fished more often, ate more fish meals of slightly larger serving sizes, and consumed more fish per year than did Whites. Although education and income were correlated, education contributed most significantly to behavior; people who did not graduate from high school ate fish more often, ate more fish per year, and ate more whole fish than people who graduated from high school. Computing consumption of fish for each person individually indicates that (1) people who eat fish more often also eat larger portions, (2) a substantial number of people consume more than the amount of fish used to compute risk to recreational fishermen, (3) some people consume more than the subsistence level default assumption (50 kg/year) and (4) Blacks consume more fish per year than Whites, putting them at greater risk from contaminants in fish. Overall, ethnicity, age, and education contributed to variations in fishing behavior and consumption.     

Optimal design for epidemiological studies subject to designed missingness

In large epidemiological studies, budgetary or logistical constraints will typically preclude study investigators from measuring all exposures, covariates and outcomes of interest on all study subjects. We develop a flexible theoretical framework that incorporates a number of familiar designs such as case control and cohort studies, as well as multistage sampling designs. Our framework also allows for designed missingness and includes the option for outcome dependent designs. Our formulation is based on maximum likelihood and generalizes well known results for inference with missing data to the multistage setting. A variety of techniques are applied to streamline the computation of the Hessian matrix for these designs, facilitating the development of an efficient software tool to implement a wide variety of designs.     

Maternal Emotion-related Socialization and Preschoolers' Developing Emotion Self-awareness

Preschoolers' ability to demonstrate awareness of their own emotion is an important socio‐emotional competence which has received increasing attention in the developmental literature. The present study examined emotion self‐awareness of happiness, sadness, and anger in response to a delay of gratification task in 78 preschool children. Maternal emotion‐related socialization behaviors (ERSBs) including reported emotional expressivity, responses to her child's emotions, and observed emotion talk, were examined as predictors of children's emotion self‐awareness skill one year later. Results show that, after controlling for receptive language ability, supportive ERSBs were predictive of high self‐awareness of happiness whereas non‐supportive ERSBs were predictive of low self‐awareness of sadness. The results demonstrate that the concordance between observed and self‐reported emotion serves as a useful index of children's awareness of their emotional experience.     

Divergent female part-time employment in Britain and Denmark and the implications for gender equity

This paper examines women's employment in Britain and Denmark, societies characterised similarly by high proportions of female employees working part‐time but by rather different gender arrangements. Part‐time working is associated with female‐carer workers; women who have reduced their hours in the labour market to bring up children and are able to do this because of the presence of an alternative source of income—usually a male breadwinner. Yet Denmark has been conceptualised as having more of ‘dual‐breadwinner’ gender arrangement than Britain. It would seem then, that part‐time working is distinctly different in these two societies. Examining this question, the paper concludes that extensive part‐time working for women, and not men, does indeed tend to reinforce a traditional male‐breadwinner model. However, the strength of this reinforcement varies, depending on the relative conditions of the part‐time labour market. These conditions vary substantially cross‐nationally and can also change rapidly within one society over time. As a result, the typical ‘role’ a part‐time job plays for women can also vary cross‐nationally and can change over time.     

MOTIVATIONAL INTERVIEWING AS AN INTERVENTION FOR AT-RISK COUPLES

Thirty-one couples participated in a pilot, motivational interviewing, intervention for at-risk couples called the Marriage Checkup (MC). The MC consisted of thorough relationship assessment and individualized feedback. It attracted substantial numbers of at-risk couples who were not otherwise seeking treatment. Partners' marital satisfaction improved significantly from pre- to post-check-up and remained improved at 1-month follow up. Partners were no longer significantly different from a non-distressed comparison group following intervention. Although not addressing the efficacy of the MC, this study supports its viability as an indicated preventive intervention with couples at-risk for severe marital distress by addressing its attractiveness, tolerability, and safety.     

Design Contradictions in the ‘New Architecture of Aid’? Reflections from Uganda on the Roles of Civil Society Organisations

This article considers how changing trends in patterns and modalities of aid are affecting the roles of civil society organisations. It draws on research carried out in Uganda in 2001 to argue that donors are adopting an oversimplified conception of the roles of CSOs. In particular, by separating ‘service delivery’ from ‘advocacy’ roles, donors fail to appreciate a situation in which organisations play several roles simultaneously, and the vital synergy that can be created between roles. Furthermore, there is a danger that the changes in funding modalities will force a new dependence on government which will restrict CSOs’ ability to carry out the very role that donors are trying to enhance — that of ‘holding government to account’.     

Ungrateful slaves? An examination of job quality and job satisfaction for male part-time workers in the UK

Research on part-time work has concentrated over many decades on the experiences of women but male part-time employment is growing in the UK. This article addresses two sizable gaps in knowledge concerning male part-timers: are men's part-time jobs of lower quality than men's full-time jobs? Are male part-timers more or less job-satisfied compared to their full-time peers? A fundamental part of both interrogations is whether men's part-time employment varies by occupational class. The article is motivated by the large body of work on female part-timers. Its theoretical framework is rooted in one of the most controversial discussions in the sociology of women workers: the “grateful slave” debate that emerged in the 1990s when researchers sought to explain why so many women expressed job satisfaction with low-quality part-time jobs. Innovatively, this article draws upon those contentious ideas to provide new insights into male, rather than female, part-time employment. Based upon analysis of a large quantitative data set, the results provide clear evidence of low-quality male part-time employment in the UK, when compared with men's full-time jobs. Men working part-time also express deteriorating satisfaction with jobs overall and in several specific dimensions of their jobs. Male part-timers in lower occupational class positions retain a clear “lead” both in bad job quality and low satisfaction. The article asks whether decreasingly satisfied male part-time workers should be termed “ungrateful slaves?” It unpacks the “grateful slave” metaphor and, after doing so, rejects its value for the ongoing analysis of part-time jobs in the formal labor market.     

Becoming invisible: The ethics and politics of imperceptibility

This speculative essay examines ‘invisible’ social identities and the processes by which they are manifested and occasionally sought. Using various literary and academic sources, and loosely informed by an unlikely combination of Stoic philosophy and post-structuralist politics, we argue that invisibility is conventionally viewed as undesirable or ‘suffered’ by individuals or groups that are disadvantaged or marginalised within society. Whilst appreciating this possibility, we argue that social invisibility can also be the result of strategies carefully conceived and consciously pursued. We suggest that forms of social invisibility can be acquired by ethically informed personal action as well as by politically informed collective action. In this context, invisibility can be seen as a strategy of escaping from institutionalised and organisational judgements and which presents a challenge to common notions of voice and identity.
