The relationship between employment quality and work-related well-being in the European Labor Force

In this article, data from the 2005 European Working Conditions Survey are used to examine the relationship between contemporary employment arrangements and the work-related well-being of European employees. By means of a Latent Class Cluster Analysis, several features of the employment conditions and relations characterizing jobs are combined in a typology of five employment arrangements: SER-like, instrumental, precarious unsustainable, precarious intensive and portfolio jobs. These job types show clear relationships with separate indicators of job satisfaction, perceived safety climate and the ability to stay in employment, as well as with an overall indicator for work-related well-being. The findings from this multifaceted approach towards employment quality raise questions about the long-term sustainability of highly flexible and de-standardized employment arrangements.     

The adrenergic receptor α-2A gene (ADRA2A) and neuropsychological executive functions as putative endophenotypes for childhood ADHD

There is resurgent interest in the psychiatric literature in endophenotypes, variables thought to more strongly reflect the effects of candidate genes than do manifest disorders. In a sample of 176 children with attention deficit hyperactivity disorder (ADHD) and 52 of their siblings, we examined the validity of several putative endophenotypes for ADHD that represent commonly used clinical measures of multiple cognitive/neuropsychological domains of executive functions (EFs). We review their distributional normality, their relations to ADHD symptoms in probands and unaffected siblings relative to nonADHD controls, and their correlation in siblings. We also tested the EF measures’ associations with the ADRA2A gene and whether they mediated or moderated the associations between ADHD and ADRA2A. Several EF measures showed association with ADRA2A, as well as moderation, but not mediation, of its association with ADHD. Implications of the results for evaluating the validity and utility of putative endophenotype measures and for finding candidate gene effects on ADHD are discussed.     

Mothers' attitudes toward fat, weight, and dieting in themselves and their children

We examined how a mother's view of her body, and fatness in general, affects her attitude toward her child's weight and eating. Mothers (N = 118) of 3–5-year-old children filled out a questionnaire designed to assess weight satisfaction, anti-fat attitudes, and how concerned and restrictive they are with regards to their child's weight and eating. We found mothers who were more fearful of being or becoming overweight themselves worried more for their children, although fearful attitudes did not predict restricting a child's eating. These results suggest that maternal attitudes toward their own weight affect their beliefs about their children's weight.     

Behavioural inhibition, anxious symptoms, and depressive symptoms: a short-term prospective examination of a diathesis-stress model

The purpose of the current study was to examine the relationship between behavioural inhibition (BI) and anxious symptoms within a diathesis-stress framework, using a short-term prospective design. In addition, we examined whether BI acts as a specific vulnerability to anxious symptoms, or as a common vulnerability to both anxious and depressive symptoms. At time 1, 384 children in grades 3 through 6 completed self-report measures of BI, anxious symptoms, and depressive symptoms. Six weeks later, they completed self-report measures of hassles, anxious symptoms, and depressive symptoms. Results demonstrated that children with high BI who experienced high levels of hassles during the 6-week follow-up interval showed increases in anxious symptoms, but not depressive symptoms.     

Strengthening the validity of population-based suicide rate comparisons: an illustration using U.S. military and civilian data

The objectives of this study were to generate precise estimates of suicide rates in the military while controlling for factors contributing to rate variability such as demographic differences and classification bias, and to develop a simple methodology for the determination of statistically derived thresholds for detecting significant rate changes. Suicide rate estimates were calculated for the military population and each service branch over 11 years, directly standardized to the 2000 U.S. population. Military rates were highly comparable across branches and were approximately 20% lower than the civilian rate. Direct adjustment essentially controlled for the demographic confounds in this sample. Applying the Poisson-based method, we demonstrate that suicide rate fluctuations as large as 20-40% in any year may be attributed to random error.     

When fit is fundamental: performance evaluations and promotions of upper-level female and male managers

Using archival organizational data, the authors examined relationships of gender and type of position (i.e., line or staff) to performance evaluations of 448 upper-level managers, and relationships of performance evaluations to promotions during the subsequent 2 years. Consistent with the idea that there is a greater perceived lack of fit between stereotypical attributes of women and requirements of line jobs than staff jobs, women in line jobs received lower performance ratings than women in staff jobs or men in either line or staff jobs. Moreover, promoted women had received higher performance ratings than promoted men and performance ratings were more strongly related to promotions for women than men, suggesting that women were held to stricter standards for promotion.     

Reactive and proactive aggression: stability of constructs and relations to correlates

The authors examined short-term temporal stability of reactive and proactive aggression, as well as short-term consistency of differential relations of reactive versus proactive aggression to 4 correlates. The authors used parent, teacher, peer, and self-report measures twice across 1 year to assess reactive aggression, proactive aggression, hyperactivity, social skills, anger expression, and depressive symptoms of 2nd-grade boys and girls (N = 57). Both subtypes of aggression remained stable across the year, even when the other subtype of aggression was explained at each assessment. Reactive aggression, but not proactive aggression, was consistently positively related to hyperactivity, poor social skills, and anger expression at each assessment.     

Socioeconomic status in childhood and adulthood: associations with dispositional optimism and pessimism over a 21-year follow-up

We examined whether dispositional optimism and pessimism (overall LOT-R and optimism and pessimism component scores) of 694 adults aged 24 and 27 were associated with socioeconomic status (SES) measured concurrently and in childhood at ages 3 and 6. SES measures included education, occupational status and unemployment, and income. Concurrent adulthood SES was associated with the overall LOT-R and optimism and the pessimism component scores. Childhood family SES predicted overall LOT-R and pessimism component scores, even after controlling statistically for the adulthood SES. Social mobility between SES of family of origin and current SES also influenced the scores. The current findings suggest that the foundation of dispositional optimism and pessimism is related to early SES of the family.     

Why walkers slip: shine is not a reliable cue for slippery ground

In a series of four studies, we investigated the visual cues that walkers use to predict slippery ground surfaces and tested whether visual information is reliable for specifying low-friction conditions. In Study 1, 91% of participants surveyed responded that they would use shine to identify upcoming slippery ground. Studies 2-4 confirmed participants' reliance on shine to predict slip. Participants viewed ground surfaces varying in gloss, paint color, and viewing distance under indoor and outdoor lighting conditions. Shine and slip ratings and functional walking judgments were related to surface gloss level and to surface coefficient of friction (COF). However, judgments were strongly affected by surface color, viewing distance, and lighting conditions--extraneous factors that do not change the surface COF. Results suggest that, although walkers rely on shine to predict slippery ground, shine is not a reliable visual cue for friction. Poor visual information for friction may underlie the high prevalence of friction-related slips and falls.
