Within-child associations between family income and externalizing and internalizing problems.

Within-child associations between family income and child externalizing and internalizing problems were examined using longitudinal data from the NICHD Study of Early Child Care and Youth Development (2004a, 2004b; N = 1,132). Variations in income effects were estimated as a function of whether families were poor, whether mothers were partnered, and the number of hours mothers and their partners were employed. On average, children had fewer externalizing problems during times when their families' incomes were relatively high than during times when their families' incomes were relatively low; the estimated benefits of increased income were greatest for children who were chronically poor. For both externalizing and internalizing problems, income was most strongly associated with problems when chronically poor children's mothers were partnered and employed.

Status and solidarity in social comparison: Agentic and communal values and vertical and horizontal directions.

Social comparison involves positioning the self relative to others on a vertical or status dimension (ranging from upward to downward comparisons) and a horizontal or solidarity dimension (ranging from contrastive to connective comparisons). Across 3 studies in which 389 undergraduates recorded everyday social comparisons (n = 4,417), downward and connective comparisons were rated as more helpful and mood enhancing than upward and contrastive comparisons. The effects of horizontal comparisons were greater for people for whom solidarity was an important value; however, the effects of vertical comparisons were not greater for people who valued status. The roles of the comparison target, topic, and situation were also explored; for example, noticing undesirable features of the target enhanced status but undermined solidarity.

Effects of goal-setting and feedback on memory performance and beliefs among older and younger adults.

This research examined the impact of goal-setting conditions on memory beliefs and performance among older and younger adults. After baseline recall and assessment of beliefs, participants were assigned to goal-setting, goals plus feedback, or control. Then, additional recall trials were followed by repeated memory beliefs assessments. For both younger and older adults, performance, motivation, and self-efficacy were affected positively by goal-setting. The impact of goals plus feedback was mixed and varied as a function of age and dependent measure. Success rates for reaching memory goals, which were low for the older adults, may have been a factor in these results. Adults' self-set recall goals were predicted initially by baseline performance and self-efficacy. On the final trial, goals were predicted by last trial performance, self-efficacy, and control beliefs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Weight loss and maintenance and changes in diet and exercise for behavioral counseling and nutrition education.

100 out of 112 women who initially were at least 20 lb overweight, but did not weigh over 220 lb completed a 16-wk program of either behavioral counseling or nutrition education. Initial weight losses were similar for both groups, but behavioral Ss (BEs) consumed significantly fewer calories and changed more on 2 of 4 exercise measures than did nutrition education Ss (NEs). Reviews of daily eating records indicated that BEs more often used diets that were nutritionally unsound. The exercise changes in both conditions were modest and highly variable. Seven-month follow-up indicated that BEs maintained significantly more weight loss than did NEs. Interviews with 92 Ss indicated that regular monitoring of eating, an exercise routine, and problem solving were associated with maintenance.

Linking job demands and resources to employee engagement and burnout: A theoretical extension and meta-analytic test.

We refine and extend the job demands–resources model with theory regarding appraisal of stressors to account for inconsistencies in relationships between demands and engagement, and we test the revised theory using meta-analytic structural modeling. Results indicate support for the refined and updated theory. First, demands and burnout were positively associated, whereas resources and burnout were negatively associated. Second, whereas relationships among resources and engagement were consistently positive, relationships among demands and engagement were highly dependent on the nature of the demand. Demands that employees tend to appraise as hindrances were negatively associated with engagement, and demands that employees tend to appraise as challenges were positively associated with engagement. Implications for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Drug discovery and introduction: regulation and overregulation

The purities of seven tetrazolium salts, obtained from various commercial sources, have been assessed by thin layer chromatography, relative extinction coefficients, and melting points. MTT and INT were largely homogeneous on thin layer chromatography, although significant variations occurred in the melting point behaviour. All the samples of TT examined were contaminated to a small extent with non-tetrazolium u.v.-absorbing material. TNBT and NBT were contaminated with small amounts of mono-tetrazolium salts, although one sample of each was heavily contaminated with another di-tetrazolium compound. Four samples of TNBT contained high melting point contaminants. BT was also contaminated with mono-tetrazolium salts, and some samples also contained di-tetrazolium salt contaminants. NT was the most heavily contaminated of all, most samples containing no less than five separate tetrazolium compounds. Prices varied widely, and in general were not related to purity. Some catalogue entries were very easy to find; others were more difficult. Few specifications were given; of these, most were arbitrary (for example, pure, grade I, and ... probably the finest INT offered anywhere.

Rorschach images of symbiosis and separation in eating-disordered and in borderline and nonborderline subjects.

The Rorschach protocols of 62 eating-disordered women were analyzed for content expressing symbiotic, separation, and counter-symbiotic strivings. Subjects were grouped into three symptom pattern groups and into borderline and nonborderline groups as measured by Gunderson's Diagnostic Interview for Borderlines (DIB). Very few differences in this content were found among the three symptom-based groups. Consistent and significant differences were found among these groups in the relation between overall Rorschach response productivity and the production of responses with this content. This suggests that the symptom patterns may reflect differing modes of self-regulation. Consistent and significant differences in the production of this content were also found between borderline and nonborderline groups, supporting clinically based claims that symbiotic Rorschach responses are diagnostic of borderline functioning.
