Adolescents’ perceptions of the ‘substance use-violence nexus’: a South African perspective

The aim of the study was to explore adolescents’ perceptions of substance use as a contributing factor to community violence by employing a conceptual framework proposed by Goldstein. Data were collected from a sample of adolescents between the ages of 15 and 16 years by means of focus group interviews. Theoretical thematic analysis was used to analyse and interpret the findings. The participants’ perceptions indicated that substance use and withdrawal symptoms induce physiological and behavioural modifications resulting in aggression and violence. The findings also suggest that participants believed that substance users frequently commit property and violent interpersonal crimes such as theft, robbery, assault and murder to procure their substances. Further, the adolescents’ perceived violence to be rooted within gang culture as well as the involvement in shared markets for illicit substance trading.     

Operationalizing environmental indicators for physical activity in older adults

This qualitative study describes environmental supports and barriers to physical activity in an older adult sample drawn from low- and high-walkable neighborhoods. Thirty-seven individuals age 55 and over were recruited and answered open-ended survey questions, with a subsample invited back to partake in a semistructured interview. Content analysis identified categories and themes linking perceptions of neighborhood-environment characteristics to activity. Emerging categories and themes did not differ across neighborhood walkability, so results are presented for both groups combined. Infrastructure was the most common category identified to encourage activity, specifically, well-maintained sidewalks, bike paths or lanes, and traffic control. Other categories of land use, landscape, and aesthetics were reported. Poorly maintained or missing sidewalks, crosswalks, bike paths or lanes, and traffic safety were categories that discouraged activity. In conclusion, the information obtained is helpful in solidifying which environmental characteristics are important to measure as they relate to activity behavior in an older adult population.

Gender‐specific or Common Classroom Norms? Examining the Contextual Moderators of the Risk for Victimization

We tested whether gender‐specific vs. common classroom norms were more powerful moderators of the association between a risk factor (rejection) and peer victimization among girls and boys. The participants were 1220 elementary schoolchildren from grades 4–6 (with 10–13 years of age). We compared different multilevel models including combined vs. separate regressions for boys and girls, as well as the effects of norms of the whole class, same‐sex classmates, and cross‐sex classmates. Among girls, the association between rejection and victimization was strongest in classes where bullying behavior was common, and anti‐bullying attitudes were rare among girls. Among boys, the strength of the slope of victimization on rejection could not be explained by either common or gender‐specific classroom norms, but boys' level of bullying behavior was related to overall classroom level of victimization. The findings suggest that contextual factors may contribute to victimization especially among high‐risk girls. The importance of exploring multiple levels of influence on children's social development is discussed.     

R&D productivity rides again?

A recent analysis of R&D productivity suggests that there are grounds for ‘cautious optimism’ that the industry ‘turned the corner’ in 2008 and is ‘on the comeback trail’. We believe that this analysis is flawed and most probably wrong. We present an alternative analysis of these same data to suggest that the industry is not yet ‘out of the woods’ and suggest that many of the systemic issues affecting pharmaceutical R&D productivity are still being resolved.

Mothers' work and child care

In “Mothers' Work and Child Care,” Julia B. Isaacs, director of the Division of Data and Technical Analysis of the Department of Health and Human Services (HHS) Office of Planning, She describes the strengths and weakness of the child care data in the main national surveys. Isaacs also examines the main data sources that HHS uses to measure the availability and quality of child care for low-income families: the Current Population Survey (CPS); the Survey of Income and Program Participation (SIPP); the National Household Education Survey (NHES); the National Survey of America's Families (NSAF); state administrative data collected by the federal government that include aggregate numbers of children receiving subsidies as well as some of the characteristics of those subsidies, such as type of provider and age of child; and state studies of those who have left the welfare rolls (leaver studies).     

Using the RE‐AIM framework to identify and describe best practice models in family‐based intervention development: A systematic review

The family unit carries with it a responsibility of possibly being the most important predictor of positive child development. The aim of this systematic review is to identify and describe best practice models or processes in family‐based intervention development. The following databases were included in the review: PsychArticles, Academic Search Complete, ERIC, SocIndex, Sage, Sabinet, and Pubmed. Peer‐reviewed, English language, qualitative, quantitative, and mixed methods in nature conducted within the last 10 years. Interventions were required to include families as part of the programme as well as describe the model or process used in intervention development. Two self‐developed data extraction tables were developed for this review. The articles included for review were heterogeneous in terms of the outcomes, and so a narrative synthesis was used. After yielding an initial search of 400 studies, 28 articles were finally included for extraction and analysis with varying levels of intervention strength. Interventions are further described in terms of reach, effectiveness, adoption, implementation, and maintenance dimensions. A feasible intervention appears to be one that is flexible, engages processes to recruit those who are most at‐risk and is facilitated by someone known to or from the same community as the participants, can retain its participants, and can be evaluated with the same participants at a minimum of 6 months later.     

REMARRIAGE AND ITS ALTERNATIVES FOLLOWING DIVORCE: MOTHER AND CHILD ADJUSTMENT

The current literature on the effects of new parental relationships following separation on the child's well-being has overemphasized remarriage, per se, and has failed to analyze other types of relationships. The present study examines how mother and child adjustment varies among four categories of "blending": (a) remarriage, (b) living together but not remarried, (c) seriously involved but not living together, and (d) not seriously involved.     

Teaching examples for the design of experiments: geographical sensitivity and the self‐fulfilling prophecy

Many scientists believe that small experiments, guided by scientific intuition, are simpler and more efficient than design of experiments. This belief is strong and persists even in the face of data demonstrating that it is clearly wrong. In this paper, we present two powerful teaching examples illustrating the dangers of small experiments guided by scientific intuition. We describe two, simple, two‐dimensional spaces. These two spaces give rise to, and at the same time appear to generate supporting data for, scientific intuitions that are deeply flawed or wholly incorrect. We find these spaces useful in unfreezing scientific thinking and challenging the misplaced confidence in scientific intuition. Copyright © 2015 John Wiley & Sons, Ltd.
