Interference effects in bimanual coordination are independent of movement type

Simultaneously executed limb movements interfere with each other. Whereas the interference between discrete movements is examined mostly from a cognitive perspective, that between rhythmic movements is studied mainly from a dynamical systems perspective. As the tools and concepts developed by both communities are limited in their applicability to the other domain, it remains unclear if a common cause underlies motor interference in both domains. We investigated the interference between simultaneously executed discrete and rhythmic wrist movements. The discrete movements' reaction time and movement time decreased with increasing rhythmic movement frequency. The discrete movements accelerated or decelerated the rhythmic movements in a manner that depended on movement frequency and the discrete movement's initiation phase. The acceleration/deceleration profile was bimodal at low frequencies and unimodal at high frequencies, mimicking the hallmark feature of rhythmic-rhythmic coordination, thus suggesting that interference between movements may be invariant across different movement types.     

Pattern of perceived stress and anxiety in pregnancy predicts preterm birth.

OBJECTIVE: To determine whether the pattern of prenatal stress, as compared to prenatal stress assessed at a single gestational time point, predicts preterm delivery (PTD). DESIGN: Perceived stress and anxiety were assessed in 415 pregnant women at 18-20 and 30-32 weeks' gestation. MAIN OUTCOME MEASURES: Gestational length was determined by last menstrual period and confirmed by early pregnancy ultrasound. Births were categorized as preterm (< 37 weeks) or term. RESULTS: At neither assessment did levels of anxiety or perceived stress predict PTD. However, patterns of anxiety and stress were associated with gestational length. Although the majority of women who delivered at term exhibited declines in stress and anxiety, those who delivered preterm exhibited increases. The elevated risk for PTD associated with an increase in stress or anxiety persisted when adjusting statistically for obstetric risk, pregnancy-related anxiety, ethnicity, parity, and prenatal life events. CONCLUSIONS: These data suggest that the pattern of prenatal stress is an important predictor of PTD. More generally, the findings support the possibility that a decline in stress responses during pregnancy may help to protect mother and fetus from adverse influences associated with PTD.     

Familialism, social support, and stress: positive implications for pregnant Latinas

This study examined the association of familialism, a cultural value that emphasizes close family relationships, with social support, stress, pregnancy anxiety, and infant birth weight. Foreign-born Latina (n = 31), U.S.-born Latina (n = 68), and European American (n = 166) women living in the United States participated in a prospective study of pregnancy in which they completed measures of familialism, social support, stress, and pregnancy anxiety during their second trimester. As expected, Latinas scored higher on familialism than European Americans. Familialism was positively correlated with social support and negatively correlated with stress and pregnancy anxiety in the overall sample. As predicted, however, the associations of familialism with social support and stress were significantly stronger among Latinas than European Americans. Moreover, higher social support was associated with higher infant birth weight among foreign-born Latinas only. Implications of cultural values for relationships and health are discussed.     

Otherness and the problem of evil: How does that which is other become evil?

In seeking to answer the question “How does that which is other become evil?” the author provides a discussion of four entwined aspects of the issue at stake; (1) difficulty in achieving clarity on the grammar of evil; (2) genocide as a striking illustration of otherness becoming evil; (3) the challenge of postnationalism as a resource for dealing with otherness in the socio-political arena; and (4) the ethico-religious dimension as it relates to the wider problem of evil.     

Maternal correlates of 2‐year‐old American Indian children's social‐emotional development in a Northern Plains tribe

The developmental experiences of very young American Indian children today are not well documented in the current literature. The present study sought to explore the social‐emotional development of American Indian toddlers living on a Northern Plains reservation, as a function of maternal variables. Mothers completed self‐report questionnaires about their experiences and their children's development. Observer ratings of children's development also were conducted. Maternal stress, substance use/abuse, perceptions of stress in the mother–child relationship, social support, and American Indian cultural identity were significantly related to children's social‐emotional development. This study is the first to explore these relationships in a Northern Plains American Indian sample of young children and their mothers. Results suggest possible points of intervention for improving the developmental outcomes of very young American Indian children.     

WILLIAM AMES'S CALVINIST AMBIGUITY OVER FREEDOM OF CONSCIENCE

Reformed Christianity's qualified embrace of freedom of conscience is perhaps best represented by William Ames (1576–1633). This essay explores Ames's interpretation of conscience, his understanding of its relationship to natural law, Scripture, and civil authority, and his vacillation on the subject of conscientious freedom. By rooting his interpretation of conscience in natural law, Ames provided a foundation for conscience as an authority whose convictions are binding and worthy of some civil respect and freedom. At the same time, his Puritan worldview ultimately required the deference of conscience to the superior manifestations of divine law in Scripture and civil institutions. As a result, Ames provided raw ingredients for a theological doctrine of freedom of conscience despite his unwillingness to commend the idea himself consistently. In this way, Ames symbolizes an ambiguity on freedom of conscience characteristic of the broader Reformed tradition.     

Inmates' perceptions of determinate and indeterminate sentences

The movement to replace indeterminate with determinate sentencing is among the most important recent developments in the criminal justice field. While the views of citizens and scholars on the subject have been widely promulgated, little is known about those of the ultimate “consumers” of sentencing reform, namely, inmates. This article examines the views of a systematic sample of inmates in a maximum security institution in Massachusetts. Subjects' opinions were sought on the relative merits of the two typs of sentencing, and possible behavioral and deterrent effects of a proposed switch to determinate sentencing. More inmates were found to be either opposed to or undecided about than in favor of determinate sentencing.
