Cry analysis detects subclinical effects of prenatal alcohol exposure in newborn infants

The threshold, latency, and peak fundamental frequency (basic pitch) of crying were sensitive to the subclinical effects of prenatal alcohol exposure through the first month of postnatal life. Whereas infants with prenatal alcohol exposure showed a lower cry pitch and higher cry threshold at 2 days of age, higher pitched cries, typical of nervous system insult, were evident at 14 and 28 days. A longer latency was also evident at 14 days.     

The importance of the individual in the ‘causal’ relationship between attractiveness and self-esteem

This paper argues that many psychological explanations underlying health and social behaviour stress the importance of the relationship between attractiveness and self-esteem. The nature of this relationship is not well understood, yet can have important implications for the individual in areas of medical intervention which involve treatment on aesthetic grounds. A survey of psychosocial factors among 1018 children aged 11-12 years is reported. The study examined the association between perception of physical attractiveness and self-esteem in order to clarify the relationship between self-esteem and self versus others' perception of attractiveness. Self-ratings of attractiveness were linked to judges' ratings to determine whether subjects underrated, over-rated, or accurately perceived their own physical attractiveness. The results showed that although ratings of general facial attractiveness by others were associated with self-perceived attractiveness, in the specific area of dental health, attractiveness (as judged by others) was not. There were no significant relationships between ratings of attractiveness by others and self-esteem. Self-perception of attractiveness, however, was significantly associated with self-esteem. Further analyses showed that children who under-rated their own facial attractiveness had a lower mean score for self-esteem than over-raters or accurate perceivers (who did not differ significantly). In contrast, under-raters of dental attractiveness had a lower mean score for self-esteem than over-raters, but did not differ significantly from accurate perceivers. Over-raters of dental attractiveness had a higher mean score for self-esteem than accurate perceivers. These finding suggest that if an over-rater were to receive treatment on aesthetic grounds it is unlikely, given that they have high self-esteem already, that such intervention will have a profound psychological impact. These data indicate the importance of determining the way in which individuals evaluate their appearance compared to others, and may help to clarify previously equivocal findings concerning the relationship between self-esteem and attractiveness.     

Terrorism research and the diffusion of ideas

The diffusion of ideas about contemporary terrorism is analyzed using a sociology of science methodology. One of the most common means of creating understandings of a phenomenon is the development and diffusion of ideas that influence the positions adopted by a wide range of actors, including government bureaucrats and decision makers, legislative and corporate bodies, and the public. How did terrorism researchers interact with these actors to construct, maintain, and modify the development and perception of contemporary terrorism? How were the ideas diffused and what impact did they have on policymakers? Did the invisible college of terrorism researchers function as an epistemic community? These questions are analyzed using an integrated research strategy that employs a number of techniques and data sources such as bibliometrics, content analysis, and citation analysis of selected terrorism research publications, biographies, and conferences, and on-line tracing of researchers’ affiliations, participations, and collaborations.     

How type of excuse defense, mock juror age, and defendant age affect mock jurors' decisions

The authors investigated the effects of mock juror age (younger vs. older), defendant age (22 vs. 65), and type of excuse defense used by defendants (a highly self-inflicted condition, Cocaine Dependency Disorder, vs. a less self-inflicted condition, Posttraumatic Stress Disorder) on mock juror decisions. Ninety-six younger and 96 older adults read a scenario and answered a questionnaire. Results indicated that the defendant using the highly self-inflicted excuse was more likely to receive a guilty verdict and a longer sentence than was the defendant using the less self-inflicted excuse. Older jurors were more certain of their verdicts and saw the defendant as more responsible for his condition than did younger jurors. Defendant age did not affect juror decisions. In addition, excuse type and juror age affected the jurors' perceptions of the victim's responsibility for the attack. The authors discuss the potential influence of juror age on perceptions of defendant responsibility.     

Social support and prognosis in patients at increased psychosocial risk recovering from myocardial infarction.

OBJECTIVE: To compare the impact of network support and different types of perceived functional support on all-cause mortality or nonfatal reinfarction for patients with a recent acute myocardial infarction (AMI). DESIGN: Participants were recruited from the Enhancing Recovery in Coronary Heart Disease (ENRICHD) trial; 2,481 AMI patients with depression or low social support were randomized to a cognitive-behavioral intervention or to a usual care control group. Data collection for certain measures of social support was limited: 2,466 participants completed the ENRICHD Social Support Inventory; 2,457 completed the Perceived Social Support Scale; 1,296 completed the Social Network Questionnaire; and 707 completed the Interpersonal Support and Evaluation List, Tangible Support subscale. Patients also completed the Beck Depression Inventory and were followed for up to 4.5 years. MAIN OUTCOME MEASURE: Time to death or nonfatal reinfarction. RESULTS: Over the follow-up period, 599 patients (24%) died or had a nonfatal AMI. Survival models controlling age, sex, race, socioeconomic status, smoking, antidepressant use, and a composite measure of increased risk revealed that higher levels of perceived social support were associated with improved outcome for patients without elevated depression but not for patients with high levels of depression. Neither perceived tangible support nor network support were associated with more frequent adverse events. CONCLUSION: AMI patients should be assessed for multiple dimensions of perceived functional support and depression to identify those at increased psychosocial risk who may benefit from treatment.     

PERCEPTIONS OF SEX DISCRIMINATION AMONG FEMALE UNIVERSITY FACULTY AND STAFF

Sixty faculty and staff women at a mid–sized university were surveyed to determine the extent to which they perceived sex discrimination. Faculty women perceived sex discrimination more than did staff women and were less likely to believe that academia was a meritocracy. Differences in perception of sex discrimination were also found based upon the gender composition of the departments. Women in departments that were male–dominated were less likely to perceive sex discrimination and more accepting of the meritocracy notion than were women in departments that were not male–dominated.

Black College Women's Career Values: A Preliminary Investigation

We identified nine values that guided the career decisions of a sample of Black college women, then explored whether these values were predicted by racial and feminist identify stage sentiments Findings from this study suggest the need for further research on the career development of women of color.
