Origins of antisocial behavior: negative reinforcement and affect dysregulation of behavior as socialization mechanisms in family interaction

Abstract: Theoretical models specifying the contribution of two social-familial mechanisms, negative reinforcement and affect dysregulation, to the development of child antisocial behavior were tested using a sample of 57 8- to 13-year-old boys referred for treatment of conduct problems. Negative reinforcement of boys' aggressive behavior and boys' affect dysregulation were found to covary with the boys' irritability toward parents and siblings and were reliable predictors of a composite measure of child antisocial behavior, defined by out-of-home placement, arrests, and school discipline incidents 2 years later. Reinforcement of aggression and affect dysregulation during family interaction may play complementary roles in the development of antisocial behavior by fostering the use of coercive means of dealing with social conflict. The findings are discussed in terms of research strategies for identifying social mechanisms contributing to child psychopathology and of implications for modification of current family interventions targeting child antisocial behavior.

Supramolecular solar cells: surface modification of nanocrytalline TiO(2) with coordinating ligands to immobilize sensitizers and dyads via metal-ligand coordination for enhanced photocurrent generation.

Abstract: An elegant method of self-assembly for modification of a TiO2 surface using coordinating ligands followed by immobilization of variety of sensitizers and a dyad is reported. This highly versatile method, in addition to testing the photoelectrochemical behavior of different zinc tetrapyrroles, allowed the use of fairly complex structures involving more than one donor entity. Utilization of the zinc porphyrin−ferrocene dyad markedly improved the current−voltage performance of the photoelectrochemical cell through an electron transfer−hole migration mechanism. Incident photon-to-current efficiency values up to 37% were obtained for the electrode modified with the dyad, signifying the importance of photocells built on the basis of biomimetic principles for efficient harvesting of solar energy.

Characteristics of job rotation in the Midwest US manufacturing sector.

Abstract: Job rotation has been advocated as a suitable intervention to control work-related musculoskeletal disorders. However, little is known regarding the prevalence of job rotation, methods used to identify jobs for rotation or the benefits or limitations of job rotation. A web-based questionnaire was developed to survey job rotation practices from Midwest US manufacturing companies. Results indicated that 42.7% of the companies contacted used job rotation, where the median time for which they had used job rotation was 5 years. Job rotation was used mainly to reduce exposure to risk factors for work-related injuries and to reduce work related injuries, whereas supervisor decisions and ergonomic analyses were used to select jobs for the rotation scheme. Major limitations to successful implementation of job rotation included rotation of individuals with medical restrictions, decreased product quality and lack of jobs to rotate to. These findings suggest that further study is needed to determine if exposure to ri...

Assessing Career Decision-Making Difficulties: A Cross-Cultural Study

Abstract: This study examines the validity of the Career Decision-Making Difficulties Questionnaire (CDDQ) in relation to its cultural relevance. Relationships between career decision-making difficulties and career indecision are also examined in relation to the two cultural groups, American and Taiwanese university students. Structural equation modeling (SEM) shows that the taxonomy of career decision-making difficulties can be reliably measured for American college students. However, the data based on the Taiwanese students has a relatively poor fit of the factorial model. Compared to the America students, Taiwanese students report more difficulties in career decision making and tend to be more indecisive in their career decision making. Differences in career decision- making difficulties between American and Taiwanese college students are discussed in light of cultural differences.

An inverse problem for the dynamical Lamé system with two sets of boundary data

Abstract: We prove uniqueness and a Holder-type stability of reconstruction of all three time-independent elastic parameters in the dynamical isotropic system of elasticity from two special sets of boundary measurements. In proofs we use Carleman-type estimates in Sobolev spaces of negative order. © 2003 Wiley Periodicals, Inc.
