The association between maternal smoking and secondhand exposure and autonomic functioning at 2-4 weeks of age

This study examined the association between maternal smoking and exposure to environmental tobacco smoke (ETS) during pregnancy and infant heart rate. Participants were 62 mother-infant dyads where mother smoked during pregnancy, 47 dyads where mother did not smoke during pregnancy but was exposed to ETS and 47 dyads where mother did not smoke and was not exposed to ETS. Average heart rate (HR) and respiratory sinus arrhythmia (RSA) were assessed at 2-4 weeks of age during sleep. Infants in both exposure groups had higher HR and lower RSA than nonexposed infants. Furthermore, boys in both exposure groups had higher HR and lower RSA than girls. These results highlight the importance of considering prenatal ETS exposure and infant gender when assessing infant outcomes.     

The classification of violence risk

The Classification of Violence Risk (COVR) is an interactive software program designed to estimate the risk that a person hospitalized for mental disorder will be violent to others. The software leads the evaluator through a chart review and a brief interview with the patient. At the end of this interview, the software generates a report that contains a statistically valid estimate of the patient's violence risk-ranging from a 1% to a 76% likelihood of violence-including the confidence interval for that estimate, and a list of the risk factors that the program took into account to produce the estimate. In this article, the development of the COVR software is described and several issues that arise in its administration are discussed.     

Native Americans and alcohol: past, present, and future

Native Americans have higher rates of alcohol use, frequency of use, and increased rates of fetal alcohol syndrome, compared with other ethnic groups (J. Hisnanick, 1992; P. A. May, 1996; J. M. Wallace et al., 2003). High prevalence rates of alcohol misuse among Native Americans must be understood in light of their unique history, which has resulted in trauma and exposure to many risk factors for problem alcohol use. Many risk factors have been identified in the general population; however, only some of these risk factors have been examined among Native American populations. The unique history and world view of Native Americans mean that, often, risk factors operate differently from the way they do in other populations. The authors discuss interventions and promising treatments.     

Adult age differences in the effects of goals on self-regulated sentence processing

The authors examined age differences in adults' allocation of effort when reading text for either high levels of recall accuracy or high levels of efficiency. Participants read a series of sentences, making judgments of learning before recall. Older adults showed less sensitivity than the young to the accuracy goal in both reading time allocation and memory performance. Memory accuracy and differential allocation of effort to unlearned items were age equivalent, so age differences in goal adherence were not attributable to metacognitive factors. However, comparison with data from a control reading task without monitoring showed that learning gains among older adults across trial were reduced relative to those of the young by memory monitoring, suggesting that monitoring may be resource consuming for older learners. Age differences in the responsiveness to (information-acquisition) goals could be accounted for, in part, by independent contributions from working memory and memory self-efficacy. Our data suggest that both processing capacity ("what you have") and beliefs ("knowing you can do it") can contribute to individual differences in engaging resources ("what you do") to effectively learn novel content from text.     

Odour‐based context reinstatement effects with indirect measures of memory: The curious case of rosemary

Previous studies examining environmental context‐dependent memory (ECDM) effects using indirect measures of memory have produced inconsistent findings. We report three experiments that examined ECDM in an indirect memory paradigm (word‐fragment completion) using ambient odours as environmental contexts. Expt 1 manipulated the odour present at learning and testing (rosemary or lemon) to produce reinstated‐context or switched‐context conditions. Reinstating rosemary led to a striking ECDM effect, indicating that indirect memory testing can be sensitive to ECDM manipulations. Odour ratings also indicated that rosemary induced a more unpleasant mood in participants than lemon. Expt 2 assessed the influence on indirect retrieval of odour‐based mood induction as well as odour distinctiveness, and indicated that rosemary's capacity to promote ECDM effects appears to arise from an additive combination of its unpleasantness‐inducing properties and its distinctiveness. Expt 3 partially supported these proposals. Overall, our findings indicate that some odours are capable of producing ECDM effects using indirect testing procedures. Moreover, it appears that it is the inherent proprieties of odours on dimensions such as unpleasantness and distinctiveness that mediate the emergence of ECDM effects, thereby explaining the particular potency of rosemary's mnemonic influence when it is reinstated.     

Antecedents and Consequences of Perceived Barriers to Obtaining Mentoring: A Longitudinal Investigation

Mentoring is prototypically intended to advance the personal and professional growth of new employees at work. Although meta‐analyses have found that receiving mentoring can result in beneficial outcomes for employees' career success, employees may perceive barriers to obtaining a mentor. The present research examined antecedents and consequences to perceived barriers to mentoring in business and administrative jobs in a field study over 2 years. Socioeconomic origin, positive affectivity, organizational development culture, and previous mentoring experience predicted perceived barriers to mentoring after 2 years. New employees' perceived barriers to mentoring at Time 1 predicted changes in mentoring received and income after 2 years. Implications of this study, including a proposed mentoring training program, and directions for future research are discussed.     

Mourning Religion: A Response

Mourning Religion is a brilliant collection of essays responding both to Freud’s essay “Mourning and Melancholia” and Peter Homans’ assertion that the academic study of religion represents a creative expression of mourning the loss of religion in secular (western) society. This essay poses questions concerning the role of theology as a mode of analysis; Ricoeur’s concept of “second naiveté” in relation to disillusionment and religion; Celia Brickman’s reflections on globalization, marginalization, and a shift in psychological language from “primitivity” to “vulnerability”; the role of the body in the work of religious studies; melancholia as “re-membering” amid multiplicity and fragmentation; and mourning as protest and resistance. The essay concludes with a reflection on ambiguity and transcendence in dialogue with Freud’s essay “On Transience.”     

Gender differences in distributive negotiation: When in the negotiation process do the differences occur?

This study tested whether the degree of association among aspiration level, intended opening offer, actual first offer, actual counter‐offer, and final agreement was moderated by negotiator gender. Results show that gender does moderate the association between the predictor variable of intended opening offer and the criterion variable of actual first offer and the relationship between intended opening offer and actual counter‐offer. Interesting, this latter association was statistically non‐significant for women and statistically significant for men. These results suggest that gender differences disadvantaging women seem to manifest with the actual first offer and the actual counter‐offer. Copyright © 2009 John Wiley & Sons, Ltd.     

Influence of properties of layered silicate minerals on adsorbed DNA surface affinity,self-assembly and nanopatterning

We report on the specific interaction between DNA and some mica-family minerals and other layered silicate structures. The interaction depends on mineral surface's crystallography, chemistry and potential. These properties are responsible for a remarkable variety of adsorption mechanisms and can be used to modulate surface self-assembly and nanopatterning of DNA. The controlled deposition of DNA onto non-conductive mineral regions with atomically flat boundaries has very attractive applications in nano-biotechnology (for example, microelectronics, microarrays and sensors). In addition, the extreme affinity discovered for some mineral surfaces, together with their ability to organize the DNA molecules, could be an indication of their catalytic potential. It may also have had relevance in the prebiotic environment, with important implications for the earth and life sciences.
