Predictors and outcomes of social network compositions: A compositional structural equation modeling approach

Proportions of a total, including social network compositions (proportions of partner, family, friends, etc.) lie in a restricted space, which challenges statistical analysis. Network compositions can be both dependent and explanatory variables and are usually measured with error by survey instruments. Structural equation models make it possible to correct measurement error bias. Coenders et al. (2011) fitted a factor analysis model to transformed network compositions. In this article, we use another transformation called an isometric log-ratio and we extend the model to include predictors and outcomes. The findings and hypotheses in the literature can be reformulated with isometric log-ratios in a more interpretable manner. For instance, we find relationships of gender with partner support, of education and extraversion with friend support, and of family support with tie multiplexity and closeness.

Changes in professional vision in the context of practice

In initial teacher education, it is a challenge to foster the development of teaching skills proximal to classroom action. In this study, the impact of a combined practical and theoretical university-based term on preservice teachers’ professional vision is investigated by a video-based approach to supervising their knowledge acquisition and assessing their learning outcomes. Participants were N = 109 preservice teachers attending a 5-month theory practice term guided through video-based courses about effective teaching and learning. We measured their changes in professional vision using the video-based tool Observer. Our results show that preservice teachers positively change their professional vision during the theory practice term, especially if they show low entry levels at the beginning. Their notes on the observed teaching lessons illustrate these changes.     

The impact of distance on knowledge transfer effectiveness in multinational corporations

This paper aims to shed light on the interplay of knowledge transfer mechanisms and distance within the MNC. While it is largely undisputed that cross-boarder knowledge flows contribute to the firm's success, our knowledge on the effects of specific transfer mechanisms is scarce. We examine the impact of different dimensions of distance to test the applicability of personal coordination mechanisms (PCM) and technology-based coordination mechanisms (TCM) in situations of differentiation and dispersion. Data on 324 knowledge transfer relationships of MNC units was used to test our hypotheses. While TCM function relatively context-free, we find that PCM are moderated by distance. Our results support moderating effects of geographic, cultural and linguistic distance, which are vital to our understanding of knowledge transfer effectiveness in MNCs.     

Developing culturally competent marriage and family therapists: treatment guidelines for non-African-American therapists working with African-American families

To serve African-American families effectively, marriage and family therapists need to develop a level of cultural competence. This content analysis of the relevant treatment literature was conducted to examine the most common expert recommendations for family therapy with African Americans. Fifteen specific guidelines were generated, including orient the family to therapy, do not assume familiarity, address issue of racism, intervene multi-systemically, do home visits, use problem-solving focus, involve religious leader, incorporate the father, and acknowledge strengths. Conceptual and empirical support for each guideline is discussed, and conclusions are made regarding culturally competent therapy with African-American families.     

Long-term impact of a district-wide school/community-based substance abuse prevention initiative on gateway drug use

This study examined long-term effects of a school/family/community substance abuse prevention partnership intervention lead by a Midwestern school district. Previous findings suggested that the program contributed to decreased tobacco and marijuana, but not alcohol, use prior to and after implementation between 1987 and 1991. The current study examined 8th-12th grade student drug use prevalence data from 1991 and 2003 to determine whether previous program effects were sustained. With one exception, reported lifetime and monthly cigarette use decreased below 1991 levels for all grades. Lifetime and monthly alcohol use decreased below 1991 levels for most grades, a result not previously detected. While still below national rates, reported lifetime use of marijuana increased for all grades over time. The intervention was effective in reducing cigarette and alcohol use over time and in suppressing marijuana use levels below national rates; however, these gains tended to erode in later high school grades.     

Trauma and stress among older adults in the criminal justice system: a review of the literature with implications for social work

The purpose of this article was to review the empirical literature that investigated trauma and stress among older adults in the criminal justice system. Nineteen journal articles published between 1988 and 2010 were identified and extracted via research databases and included mixed age samples of adjudicated older and younger adults (n = 11) or older adult only samples (n = 8). Findings revealed past and current trauma and stress, consequences and/or correlates, and internal and external coping resources among aging offenders. The implications and future directions for gerontological social work, research, and policy with older adults in the criminal justice system are advanced.     

Combining Dyslexia and Mothering: Perceived Impacts on Work

Previous studies have provided an insight into the lives of disabled mothers, but little attention has been paid to disabled working mothers. This paper draws on interviews with women who had a formal diagnosis of dyslexia, to discuss: particular difficulties when combining work and mothering; the perceived positive impacts on work and education, of becoming a mother; unsupportive managers; what some mothers found helpful in order to maintain work; and the diversity between experiences. We conclude that for those already on a career path before having children, some of their experiences could have been seen as an amplification of what other working mothers face. However, a difference was that the added time taken up with mothering meant they became more vulnerable to ‘exposing’ their impairment at work. In contrast, for dyslexic women who were yet to attain a high status in education and work, motherhood encouraged them to initiate their career.
