Leaders' and subordinates' attachment orientations,emotion regulation capabilities and affect at work: A multilevel analysis

Two studies examined relationships between leaders' and subordinates' attachment orientations, emotion regulation capabilities, and affective experience and satisfaction at work. As expected, supervisors' and subordinates' insecure attachment orientations (higher anxiety and avoidance) were associated with own positive affect and satisfaction at work. Supervisors' anxious attachment orientation was associated with subordinates' lower positive affect and satisfaction at work. Contrary to hypotheses, supervisors' higher avoidance was associated with subordinates' lower negative affect and higher job satisfaction. Supervisors' emotion regulation capabilities did not mediate relationships between supervisors' insecure attachment orientations and supervisors' own or subordinates' affect and job satisfaction as expected. However, subordinates' emotion regulation capabilities interacted with supervisors' attachment orientations to predict subordinates' emotion experience at work. The results contribute to an understanding of attachment orientations' emotion dynamics in leader–follower interaction, pointing in particular to perceptual and affect-related processes at different levels of analysis.     

A Risk-Based Approach to Setting Priorities in Protecting Bridges Against Terrorist Attacks

This article presents an approach to the problem of terrorism risk assessment and management by adapting the framework of the risk filtering, ranking, and management method. The assessment is conducted at two levels: (1) the system level, and (2) the asset-specific level. The system-level risk assessment attempts to identify and prioritize critical infrastructures from an inventory of system assets. The definition of critical infrastructures offered by Presidential Decision Directive 63 was used to determine the set of attributes to identify critical assets--categorized according to national, regional, and local impact. An example application is demonstrated using information from the Federal Highway Administration National Bridge Inventory for the State of Virginia. Conversely, the asset-specific risk assessment performs an in-depth analysis of the threats and vulnerabilities of a specific critical infrastructure. An illustration is presented to offer some insights in risk scenario identification and prioritization, multiobjective evaluation of management options, and extreme-event analysis for critical infrastructure protection.     

Popular and Rejected Children's Reasoning Regarding Negative Emotions in Social Situations: The Role of Gender

Two studies compared popular and rejected children's reasoning regarding social interactions involving negative emotions. The first study, with 23 rejected and 23 popular 10‐ to 11‐year‐olds, involved hypothetical social scenarios where a classmate ‘victim’ was likely to experience a negative emotion. Although popular and rejected children both recognized negative emotions and were equally likely to suggest helping behaviour to aid the victim, there were gender effects on the type of helping behaviour suggested. Specifically, popular girls were significantly more likely to offer comforting behaviour than advice whereas popular boys offered advice more than comfort; no such preferences were exhibited by the rejected children. Furthermore, popular girls were significantly more likely than other children to refer to emotional states when justifying their helping response. In the second study, 30 popular and 30 rejected eight‐ to 10‐year‐olds identified the motives behind story characters' efforts to mask negative emotions. Popular girls were more likely to identify the target motives than rejected girls, but no such difference was apparent for the boys. The results are discussed in the light of evidence regarding gender differences in peer interaction patterns.     

Focus on the first years: Correlates of substantiation of child maltreatment for families with children 0 to 4

The overall purpose of this study was to examine the correlates of substantiation of child neglect or child abuse in children 0–48 months of age in five areas: (1) child characteristics, (2) parent characteristics, (3) home characteristics, (4) social characteristics, and (5) maltreatment characteristics. A second purpose was to compare the results of this study to the current body of child maltreatment research.This study uses an ex-post facto design. A random sample of cases from a large metropolitan area in the southwest was obtained. Families whose cases were substantiated for maltreatment were compared to families whose cases were not substantiated. The exposure of children to a dangerous environment and poor parental skill were predictive of the substantiation in the multivariate analysis. Parents with fewer parenting skills, such as the inability to effectively communicate, lack of impulse control and use of harsh discipline, were predictive of child maltreatment in the multivariate analysis. The bivariate analysis revealed additional 22 variables as correlates of the substantiation within the 5 factors.     

Violence Exposure and Drug Use in Central American Youth: Family Cohesion and Parental Monitoring as Protective Factors

Associations between witnessing serious violence and drug use, and the protective influences of family cohesion and parental monitoring, were investigated among 9,840 adolescents (50.5% female, M age=15.29 years, SD=1.76) living in Panama and Costa Rica. After accounting for demographics and parental and sibling substance use, witnessing serious violence was associated with greater drunkenness, tobacco use, number of illicit drugs used, and problems with drugs and alcohol. In every analysis, exposure to violence was associated with more drug use, while family cohesion and parental monitoring attenuated risk. Further, family cohesion and parental monitoring exerted a protective‐stabilizing effect on number of illicit drugs used and on problems with drugs and alcohol. There were few interactions with age. Implications for prevention are discussed.     

Labor Force Transitions after Childbirth Among Five Birth Cohorts in Sweden

This article describes part-time work in Sweden and performs a multivariate analysis of the choice between part-time work, full-time work, and other activities in connection with childbirth among five birth cohorts of women. Results show that the combination of market work and family is common, but heterogeneity exists among women in the sample analyzed. Previous labor force participation proves important when it comes to returning to the labor market. The extent of previous labor force participation is also important, regardless of sector of, when it comes to the return to part-time or full-time work. Career orientation and social background also prove significant, some indicators probably working indirectly through higher education and different preferences.     

Markov random-field models for estimating local labour markets

Summary. This work is motivated by data on daily travel-to-work flows observed between pairs of elemental territorial units of an Italian region. The data were collected during the 1991 population census. The aim of the analysis is to partition the region into local labour markets. We present a new method for this which is inspired by the Bayesian texture segmentation approach. We introduce a novel Markov random-field model for the distribution of the variables that label the local labour markets for each territorial unit. Inference is performed by means of Markov chain Monte Carlo methods. The issue of model hyperparameter estimation is also addressed. We compare the results with those obtained by applying a classical method. The methodology can be applied with minor modifications to other data sets.     

Coalitional economies with public projects

We prove that the welfare theorems hold in the framework of coalitional exchange economies with public projects, both in case of pure exchange and in the presence of production. The space of agents is assumed to be non-atomic (single traders are negligible) and infinitely many commodities are allowed to be present on the market.     

Models of Neurotoxicity: Extrapolation of Benchmark Doses in Vitro

In risk assessment, no observed exposure level (NOAEL) and benchmark dose (BMD) are usually derived either from epidemiological studies in humans or from animal experiments. In many in vitro studies, concentration-effect/response curves have been analyzed using different mathematical models finalized to the identification of EC50. In the present article, we propose a model to fit dose-response curves in vitro. The BMD approach has been used to compare the cell viability (MIT assay) of different rat (C6 and PC12, glial and neuronal, respectively) and human cell lines (D384 and SK-N-MC, glial and neuronal, respectively) after 24-hour exposure to the following neurotoxic substances: manganese chloride (MnCl2), methyl-mercury (Me-Hg), and the enantiomers of styrene oxide (SO). For all rat and human cell lines, the potency of the examined compounds was: MnCl2 < S-SO < R-SO < Me-Hg. A preliminary comparison with in vivo toxicity data for these substances gave rise to consistent results. Whereas a reasonable agreement between in vitro and in vivo data has been found for Mn and styrene oxide, a wide scatter of LOAEL has been reported for Me-Hg and these appear to be either much higher or lower than the BMD for the MIT assay we observed in vitro.
