Adolescent Sibling Relationship Quality and Adjustment: Sibling Trustworthiness and Modeling,as Factors Directly and Indirectly Influencing These Associations

The main goal of this study was to examine the direct and moderating effects of trustworthiness and modeling on adolescent siblings' adjustment. Data were collected from 438 families including a mother, a younger sibling in fifth, sixth, or seventh grade (M = 11.6 years), and an older sibling (M = 14.3 years). Respondents completed Web‐based surveys describing sibling conflict and warmth. Siblings reported on trustworthiness and modeling, and mothers described adjustment. Sibling conflict was directly associated with internalizing and externalizing behaviors for both siblings. The older siblings' reports of trustworthiness were directly associated with the outcome measures. The younger siblings' reports of trustworthiness were less directly associated, but a possible salutary effect was most evident under the highest levels of sibling conflict or warmth. Higher sibling modeling was a risk factor for adjustment problems in relations characterized by high conflict. Results support exploring trustworthiness as a key dimension of sibling relations.     

Childhood behavioral and emotional disorders

We reviewed the literature on family treatment for childhood behavioral and emotional disorders and found an increase in the number of studies since 1995; however there was significant variation by disorder and therapy model. There is substantially more research on externalizing disorders (i.e., conduct disorder, attention deficit hyperactivity disorder, oppositional defiant disorder) then internalizing disorders, depression and anxiety disorders. The data support the conclusion that family-based interventions produce results comparable to individually oriented interventions, and in some cases family-based interventions are superior to individual treatments. To date, cognitive behavioral family therapy and parent management have been the two models studied, almost exclusively. Implications for family therapy and future research are considered.     

Mixture structure analysis using the Akaike Information Criterion and the bootstrap

Given i.i.d. observations x1,x2,x3,...,xn drawn from a mixture of normal terms, one is often interested in determining the number of terms in the mixture and their defining parameters. Although the problem of determining the number of terms is intractable under the most general assumptions, there is hope of elucidating the mixture structure given appropriate caveats on the underlying mixture. This paper examines a new approach to this problem based on the use of Akaike Information Criterion (AIC) based pruning of data driven mixture models which are obtained from resampled data sets. Results of the application of this procedure to artificially generated data sets and a real world data set are provided.     

Evaluating Application Service Provisioning Using System Dynamics Methodology

Despite the hype surrounding the value‐added potential of e‐business for contemporary firms, the recent technology downturn was marked by poor customer satisfaction from investment in e‐business initiatives. An apparent mismatch between customer expectations and vendor offerings suggested a lack of appropriate methods and techniques for evaluating e‐business. This article draws from a longitudinal research study on the deployment, hosting and integration of application service provisioning (ASP), an e‐business model targeted mainly at small and medium‐sized businesses (SMBs). Using system dynamics as a methodology that addresses the inherent complexity of the ASP model, the article demonstrates how a series of complex inter‐relationships between key performance indicators (KPIs) will impact the business value for customers from ASP vendor products and services. The lessons from this research will be particularly relevant for existing and future ASP vendors and customers.     

Adoption and Antisocial Personality: Genetic and Environmental Factors Associated with Antisocial Outcomes

The present review critically evaluates evidence from adoption studies on the heritability of antisocial personality, interactions between genetic predispositions and the characteristics of adoptive mothers and fathers, and both the methodological and diagnostic shortcomings of existing studies. The article concludes with directions and suggestions for future research and practice.     

The Changing Institution of Marriage: Adolescents’ Expectations to Cohabit and to Marry

Cohabitation has become part of the pathway toward marriage. Prior work focuses on expectations to marry and has ignored cohabitation. Although most young adults are not replacing marriage with cohabitation, but instead cohabit and then marry, it is important to study adolescents’ joint expectations to cohabit as well as marry. Our analyses draw on recently collected data from the Toledo Adolescent Relationships Study (N = 1,293). We find that adolescents are less certain about their cohabitation than marriage expectations. Dating and sexual experience, traditional values, prosocial activities, and parents influence adolescents’ union formation expectations. The findings from this work suggest that adolescents are including cohabitation as part of their future life trajectories but rarely envision cohabitation as substituting for marriage.     

Social Work Field Educators' Views on Student Specific Learning Needs

Each year a significant proportion of students withdraw from placement in time to avoid penalty, while others fail. This article reports on a small field education research project that identified common learning issues for first placement students. Eighteen experienced supervising field educators (FEs), participated in semi structured focus groups, and identified repeat areas of difficulty in student learning that they had managed as supervisors. They also identified strategies that had been efficacious in supporting student learning. The research undertaken in 2010–2011 identified three specific themes relating to difficulties in student learning: specific student characteristics that required additional support; the university/FE partnership; student proficiency in using supervision. The findings suggest that a students' right to privacy must be considered in the provision of educational support, and that support is most effective when there is a strong partnership between the FE and university. In addition, further development of field education pedagogy may be needed to embed theory and skills related to the use of supervision and reflective learning.
