This research examines maternal smoking during pregnancy and risk for poorer executive function in siblings discordant for exposure. Data (N = 173 families) were drawn from the Missouri Mothers and Their Children study, a sample, identified using birth records (years 1998–2005), in which mothers changed smoking behavior between two pregnancies (Child 1 [older sibling]: M age = 12.99; Child 2 [younger sibling]: M age = 10.19). A sibling comparison approach was used, providing a robust test for the association between maternal smoking during pregnancy and different aspects of executive function in early-mid adolescence. Results suggested within-family (i.e., potentially causal) associations between maternal smoking during pregnancy and one working memory task (visual working memory) and one response inhibition task (color-word interference), with increased exposure associated with decreased performance. Maternal smoking during pregnancy was not associated with stop-signal reaction time, cognitive flexibility/set-shifting, or auditory working memory. Initial within-family associations between maternal smoking during pregnancy and visual working memory as well as color-word interference were fully attenuated in a model including child and familial covariates. These findings indicate that exposure to maternal smoking during pregnancy may be associated with poorer performance on some, but not all skills assessed; however, familial transmission of risk for low executive function appears more important.

Dr. Irving I. Gottesman was very creative in applying twin research designs to test hypotheses and predictions about human behavior. Two designs stand out among others: twins reared apart from birth and the twin-family study. I (NS) was inspired to incorporate both of these approaches into my own research programs at California State University, Fullerton. Gottesman's involvement and contributions to reared-apart twin research are described, followed by selected findings from the Minnesota Study of Twins Reared Apart (MISTRA), the Fullerton Study of Chinese Twins Reared Apart (CTA), a case report on separated monozygotic (MZ) female twins from South Korea, and doubly exchanged MZ male twin pairs from Colombia, South America. Recent findings from an ongoing twin-family study of social closeness, and future directions, are also presented. [ABSTRACT FROM AUTHOR]

BackgroundImpairments in key neuropsychological domains (e.g. working memory, attention) and social cognitive deficits have been implicated as intermediate (endo) phenotypes for bipolar disorder (BD), and should therefore be evident in unaffected relatives.MethodNeurocognitive and social cognitive ability was examined in 99 young people (age range 16–30 years) with a biological parent or sibling diagnosed with the disorder [thus deemed to be at risk (AR) of developing BD], compared with 78 healthy control (HC) subjects, and 52 people with a confirmed diagnosis of BD.ResultsOnly verbal intelligence and affective response inhibition were significantly impaired in AR relative to HC participants; the BD participants showed significant deficits in attention tasks compared with HCs. Neither AR nor BD patients showed impairments in general intellectual ability, working memory, visuospatial or language ability, relative to HC participants. Analysis of BD-I and BD-II cases separately revealed deficits in attention and immediate memory in BD-I patients (only), relative to HCs. Only the BD (but not AR) participants showed impaired emotion recognition, relative to HCs.ConclusionsSelective cognitive deficits in the capacity to inhibit negative affective information, and general verbal ability may be intermediate markers of risk for BD; however, the extent and severity of impairment in this sample was less pronounced than has been reported in previous studies of older family members and BD cases. These findings highlight distinctions in the cognitive profiles of AR and BD participants, and provide limited support for progressive cognitive decline in association with illness development in BD.

BackgroundEtiological theory and prior research with small or selected samples suggest that interpersonal violence clusters in families. However, the strength and pattern of this aggregation remains mostly unknown.MethodWe investigated all convictions for violent crime in Sweden 1973–2004 among more than 12.5 million individuals in the nationwide Multi-Generation Register, and compared rates of violent convictions among relatives of violent individuals with relatives of matched, non-violent controls, using a nested case–control design.ResultsWe found strong familial aggregation of interpersonal violence among first-degree relatives [e.g. odds ratio (OR)sibling 4.3, 95% confidence interval (CI) 4.2–4.3], lower for more distant relatives (e.g. ORcousin 1.9, 95% CI 1.9–1.9). Risk patterns across biological and adoptive relations provided evidence for both genetic and environmental influences on the development of violent behavior. Familial risks were stronger among women, in higher socio-economic strata, and for early onset interpersonal violence. There were crime-specific effects (e.g. ORsibling for arson 22.4, 95% CI 12.2–41.2), suggesting both general and subtype-specific familial risk factors for violent behavior.ConclusionsThe observed familiality should be accounted for in criminological research, applied violence risk assessment, and prevention efforts.

This study extends Goffman's idea that frames are laminated in various ways in interaction by demonstrating how work and play frames are interrelated in two distinct ways in naturally occurring family conversations. An analysis of excerpts from everyday interactions between parents and young children in three families illustrates how frames of play and parenting are laminated (i) by using language to sequentially transform inter- action from a literal frame to a play frame (reframing), and (ii) by creating two definitions of the social situation simultaneously through language and sometimes through physical actions as well (blending frames). It identifies linguistic and paralinguistic features by which these laminations are accomplished and shows how the parents in each family use the two different types. Finally, the analysis demonstrates in what ways play constitutes "work" for parents, contributing to our understanding of play as both ambiguous and "paradoxical." [ABSTRACT FROM AUTHOR]

In an attempt to counter changes in family structures, a number of nation states are designing policies to make men fit into families. In the case of the USA, decision makers view fatherhood and marriage as the cure for poverty among African Americans. To assert that training these men to be better fathers and husbands will help them improve other dimensions of their lives (particularly poverty) is a good idea, but it is also simplistic. Decision makers rely on an intra-group, which privileges an individualistic and cultural approach, in their development of policies. This approach tends to ignore that other subsystems, such as previously existing policies, can have an impact on the effectiveness of marriage and fatherhood promotion. Using the USA as a case study, I hypothesise that the effectiveness of fatherhood and marriage promotion is limited because of their interaction with other policies. Fatherhood and marriage promotion initiatives will be negatively affected by the absence of a progressive national urban policy, particularly in the area of economic development and in the context of current crime policies. The socio-economic and cultural reality faced by African American men must be incorporated into the decision-making processes in order to identify the most effective policies. [ABSTRACT FROM AUTHOR]

Although gender-based division of labour and the identity theory of stress suggest that the relationship between work and family demands and life stress may vary as a function of gender, it is largely unknown whether these arguments are also valid in China. To address this gap in the existing literature, the current study investigates the gender differences in perceived work and family demands, and the effects of these perceived demands on the life stress of Chinese male and female employees. The study of 153 married Chinese employees found that Chinese women perceived a higher level of family demands than did Chinese men, whereas there was no significant gender difference in the perception of work demands. In addition, while perceived family demands were similarly related to life stress differently for men and women, perceived work demands were associated more strongly with the life stress of men than that of women.

The article investigates alternative assumptions about sharing within the family and their effects on the distribution of income. Previous studies on the topic have assumed that income is redistributed between the sexes within the family. Using data from the British Family Expenditure Survey for 1968 and 1986, the researchers contrast two assumptions about sharing within the family; the conventional assumption of equal sharing or "pooling," and an alternative of "minimum sharing." Under each assumption, they examined the composition of extreme quintiles of the income distribution, and compute the numbers of men and women falling below an arbitrary "poverty line." The contribution to inequality of the net transfers between the sexes and other sources of income is also examined. It has been estimated that resource transfers between spouses could, if all income is pooled, account for about one third of married couples' pooled incomes in 1986 and about 56 per cent of the inequality of married women's incomes. Taking the bottom quintile of pooled income as an arbitrary "poverty line," it has been noted that 15 per cent of married people would have been below this line in 1986 if all incomes were pooled. On the minimum sharing assumption, 52 per cent of married women, but only 11 per cent of married men would have been under the line.

Whilst quantitive and 'positivist' modes of comparative social policy can reveal significant structural factors involved in the making of welfare states, they too often ignore the role of human agency, intention and political processes. A critical-historical comparative case study of the introduction of 'child endowment' and of 'family allowances' respectively in Australia (1941) and in Canada (1944) reminds us of the interplay between structural constraints and human agency in the history of welfare states. Detailed analysis suggests that institutionalised arrangements in Australia after 1905 to resolve capital-labour conflict via arbitral and wage fixation mechanisms put the question of the adequacy of wages in meeting family needs and with it proposals for child endowment onto the public agenda as early as 1920. In Canada the absence of such mechanisms, and alternative welfare arrangements to deal with family welfare, combined to keep such proposals off the public agenda. After 1939 the development of 'war economies' in Australia and Canada created common contradictions for governments, trying to maintain both industrial peace and anti-inflation policies, which the introduction of family allowances in both countries were attempts to resolve. Consideration is also given to a range of political problems and contexts in both countries which this particular policy measure attempted to deal with. [ABSTRACT FROM AUTHOR]
