A diathesis-stress model of engagement in risky behaviors in Chinese adolescents

The current study examined whether the association between the occurrence of negative events and increased engagement in risky behavior is moderated by maladaptive and/or adaptive coping strategies. At time 1, 411 adolescents (ages 14–19) from Yue Yang, Hunan, completed self-report measures assessing coping strategies, engagement in risky behaviors, and the occurrence of negative events. Once a month for the subsequent 6 months, adolescents completed measures assessing engagement in risky behaviors and the occurrence of negative events. In line with our hypotheses, results of hierarchical linear modeling analyses indicated that adolescents possessing high levels of maladaptive coping strategies reported greater engagement in risky behaviors following the occurrence of negative events than adolescents possessing low levels. In contrast to our hypotheses, the association between the occurrence of negative events and increased engagement in risky behavior was not moderated by adaptive coping strategies.     

What Would Jesus Buy: American Consumption of Religious and Spiritual Material Goods

This article examines an important and understudied part of the sociological study of religion: consumption of religious materials. We use data from the Baylor Religion Survey and present an initial look at which Americans read the Left Behind series, viewed The Passion of the Christ , or purchased religious paraphernalia such as "What Would Jesus Do" bracelets. Drawing on cultural consumption and religious capital research we explore class, demographic, and religious influences on consumption patterns. We find some support for each of these perspectives, which suggests that religious consumption is not a subset of cultural consumption nor of religious practice but is some combination of both.     

Bayes nets and babies: infants' developing statistical reasoning abilities and their representation of causal knowledge

A fundamental assumption of the causal graphical model framework is the Markov assumption, which posits that learners can discriminate between two events that are dependent because of a direct causal relation between them and two events that are independent conditional on the value of another event(s). Sobel and Kirkham (2006) demonstrated that 8-month-old infants registered conditional independence information among a sequence of events; infants responded according to the Markov assumption in such a way that was inconsistent with models that rely on simple calculations of associative strength. The present experiment extends these findings to younger infants, and demonstrates that such responses potentially develop during the second half of the first year of life. These data are discussed in terms of a developmental trajectory between associative mechanisms and causal graphical models as representations of infants' causal and statistical learning.     

Two Dimensions of the Ethical Problems Related to Nanotechnology

The current literature on nanoethics focuses on a wide array of topics such as equity, privacy, military, environment, human enhancement, intellectual property, and security. The identification of those topics leads to the adoption of an ethical stance, which we call the in itself dimension. In this article we argue that even though it is correct to identify the areas where ethical problems are imperative to deal with (in itself dimension), it is a partial approach. This is because the in itself dimension pays no attention to another ethical stance; one that does not have anything to do with individual or collective responsibilities, but rather with the socio-economic system into which those responsibilities are embedded. We call this second issue the contextual dimension.     

Asymmetrical Body Perception: A Possible Role for Neural Body Representations

ABSTRACT— Perception of one's body is related not only to the physical appearance of the body, but also to the neural representation of the body. The brain contains many body maps that systematically differ between right- and left-handed people. In general, the cortical representations of the right arm and right hand tend to be of greater area in the left hemisphere than in the right hemisphere for right-handed people, whereas these cortical representations tend to be symmetrical across hemispheres for left-handers. We took advantage of these naturally occurring differences and examined perceived arm length in right- and left-handed people. When looking at each arm and hand individually, right-handed participants perceived their right arms and right hands to be longer than their left arms and left hands, whereas left-handed participants perceived both arms accurately. These experiments reveal a possible relationship between implicit body maps in the brain and conscious perception of the body.     

Gender differences in the relationships of cardiovascular symptoms and somatosensory amplification to mortality

Symptoms of angina and dyspnea predict coronary artery disease and death less well in women than in men. Greater somatosensory amplification - a psychosocial propensity to report symptoms of physical discomfort - may lead women to report relatively high levels of angina and dyspnea for reasons unrelated to coronary disease, reducing their associations with mortality. We assessed this hypothesis in a nationally representative survey of U.S. adults. When stratified by gender, angina and dyspnea significantly predicted mortality among men, but predicted it less well among women. After adjusting for amplification, cardiovascular symptoms did not predict mortality among women, but amplification was positively associated with mortality among older women.     

Determining risk in pediatric research with no prospect of direct benefit: time for a national consensus on the interpretation of federal regulations

United States federal regulations for pediatric research with no prospect of direct benefit restrict institutional review board (IRB) approval to procedures presenting: 1) no more than "minimal risk" ( section sign 45CFR46.404); or 2) no more than a "minor increase over minimal risk" if the research is commensurate with the subjects' previous or expected experiences and intended to gain vitally important information about the child's disorder or condition ( section sign 45CFR46.406) (DHHS 2001). During the 25 years since their adoption, these regulations have helped IRBs balance subject protections with the pursuit of scientific knowledge to advance children's welfare. At the same time, inconsistency in IRB application of these regulations to pediatric protocols has been widespread, in part because of the ambiguity of the regulatory language. During the past decade, three federally-charged committees have addressed these ambiguities: 1) the National Human Research Protections Advisory Committee (NHRPAC) (Washington, DC), 2) the Institute of Medicine (IOM) Committee on the Ethical Conduct of Clinical Research Involving Children (Washington, DC); and 3) the United States Department of Health and Human Services Secretary's Advisory Committee for Human Research Protections (SACHRP) (Washington, DC). The committees have reached similar conclusions on interpretation of language within regulations section sign section sign 45CFR46.404 and 406; these conclusions are remarkably consistent with recent international recommendations and those of the original National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (1977) report from which current regulations are based. Drawing on the committees' public reports, this article identifies the ethical issues posed by ambiguities in regulatory language, summarizes the committees' deliberations, and calls for a national consensus on recommended criteria.     

Sequelae of Aggression in Acutely Suicidal Adolescents

The consequences of aggression on problem course and suicide risk were examined in 270 acutely suicidal adolescents (ages 12-17 years; 184 girls). Participants were assessed during psychiatric hospitalization (T1), 6-months post-hospitalization (T2), and 15 or more months post-hospitalization (T3). Study variables included self- and parent-reported aggression; self-reported internalizing symptoms, suicidal ideation, suicide attempt, and adverse events; and clinician-rated suicidal behavior. Aggression was not directly related to suicide attempt concurrently or prospectively. However, among more aggressive youth, internalizing symptoms were more predictive of T3 suicide attempt than among less aggressive youth. T1 aggression predicted aggressive incidents and the likelihood of incarceration prior to T3. Two-level hierarchical linear modeling indicated that self-reported aggression and internalizing problems were linked in terms of severity and rates of decline over time. Overall, parent-reported aggression was negatively associated with suicidal ideation. Findings highlight (a) the continuity and consequences of aggression, (b) a possible role of aggression in worsening suicide risk factors and potentiating suicide attempt, and (c) the importance of ongoing research on subtypes of suicidal adolescents.
