Achieving high quality and long‐lasting matches in youth mentoring programmes: a case study of 4Results mentoring

Mentoring programmes show significant promise for enhancing the well‐being of youth with complex needs. Research indicates that high quality mentoring, although difficult to achieve, positively impacts youth development across behavioural, social, emotional and academic domains. The difficulty of sustaining long‐term matches between mentors and youth, however, remains an important concern for the field of mentoring, as foreshortened matches can be harmful to youth. The 4Results mentoring programme has been identified as a Promising Practice through the Washington State Inventory of child‐serving behavioural and mental health programmes and has developed a unique infrastructure to support critical programme values such as match longevity. In 7 years, the programme has successfully retained 98% of mentors for at least 1 year with an average match length of 3.7 years. The following article describes the programme's guiding philosophy and approach to recruiting and training mentors in the context of existing best practices research.     

A Bayesian dose‐finding design for drug combination clinical trials based on the logistic model

In early phase dose‐finding cancer studies, the objective is to determine the maximum tolerated dose, defined as the highest dose with an acceptable dose‐limiting toxicity rate. Finding this dose for drug‐combination trials is complicated because of drug–drug interactions, and many trial designs have been proposed to address this issue. These designs rely on complicated statistical models that typically are not familiar to clinicians, and are rarely used in practice. The aim of this paper is to propose a Bayesian dose‐finding design for drug combination trials based on standard logistic regression. Under the proposed design, we continuously update the posterior estimates of the model parameters to make the decisions of dose assignment and early stopping. Simulation studies show that the proposed design is competitive and outperforms some existing designs. We also extend our design to handle delayed toxicities.

Statistical Modeling of Fire Occurrence Using Data from the Tōhoku,Japan Earthquake and Tsunami

In this article, we develop statistical models to predict the number and geographic distribution of fires caused by earthquake ground motion and tsunami inundation in Japan. Using new, uniquely large, and consistent data sets from the 2011 Tōhoku earthquake and tsunami, we fitted three types of models—generalized linear models (GLMs), generalized additive models (GAMs), and boosted regression trees (BRTs). This is the first time the latter two have been used in this application. A simple conceptual framework guided identification of candidate covariates. Models were then compared based on their out‐of‐sample predictive power, goodness of fit to the data, ease of implementation, and relative importance of the framework concepts. For the ground motion data set, we recommend a Poisson GAM; for the tsunami data set, a negative binomial (NB) GLM or NB GAM. The best models generate out‐of‐sample predictions of the total number of ignitions in the region within one or two. Prefecture‐level prediction errors average approximately three. All models demonstrate predictive power far superior to four from the literature that were also tested. A nonlinear relationship is apparent between ignitions and ground motion, so for GLMs, which assume a linear response‐covariate relationship, instrumental intensity was the preferred ground motion covariate because it captures part of that nonlinearity. Measures of commercial exposure were preferred over measures of residential exposure for both ground motion and tsunami ignition models. This may vary in other regions, but nevertheless highlights the value of testing alternative measures for each concept. Models with the best predictive power included two or three covariates.     

Executive function and theory of mind as predictors of aggressive and prosocial behavior and peer acceptance in early childhood

Executive function (EF) and theory of mind (ToM) are related to children's social interactions, such as aggression and prosocial behavior, as well as their peer acceptance. However, limited research has examined different forms of aggression and the moderating role of gender. This study investigated links between EF, ToM, physical and relational aggression, prosocial behavior and peer acceptance and explored whether these relations are gender specific. Children (N = 106) between 46‐ and 80‐months‐old completed tasks assessing cool and hot EF and ToM. Teaching staff rated children's aggression, prosocial behavior, and peer acceptance. EF and ToM predicted physical, but not relational, aggression. Poor inhibition and delay of gratification were uniquely associated with greater physical aggression. EF and ToM did not predict prosocial behavior or peer acceptance. Added to this, gender did not moderate the relation between either EF or ToM and social outcomes. The correlates of aggression may therefore differ across forms of aggression but not between genders in early childhood.     

Response to Young and Wolf: goal attainment in urban ecology research

Our critique focuses on the poorly defined key concepts, methodological inconsistencies, circular research design, and over-reaching substantive claims made by Young and Wolf. We suggest that Young and Wolf have provided an assessment of the Urban Ecosystems journal, not of urban ecology as a field. We conclude by identifying questions to guide a bibliometric analysis that focuses on a collaborative and interdisciplinary future of urban ecology (how are participating disciplines contributing to urban ecological research and scholarship; what theories and conceptual frameworks are being used, and how are these theories being tested and modified; and what mixed methodologies are being developed to collect data to address complex urban issues that are inherently interdisciplinary). We take seriously Young and Wolf’s call for a “fundamental discussion as to if and how the intentions of the field have been or need to be updated” and argue that such a discussion requires a more inclusive, rigorous, and meaningful identification of the “core” of urban ecology literature than provided.     

Progress Toward Title IX Compliance: The Effect of Formal and Informal Enforcement Mechanisms*

Objective. This article examines the factors that determine whether an intercollegiate athletic program is in compliance with Title IX, the statute requiring gender equity in educational programs. Methods. I conduct a series of econometric regressions that examine the compliance status of Division I institutions as well as the progress they have made toward compliance. Results. Large institutions and institutions with a lower percentage of female undergraduates are more likely to be in compliance. Institutions with football programs are less likely to be in compliance as are schools in the south. The effect of football revenues, operating budgets, and NCAA sanctions varies across division as well as compliance area. Conclusions. The results of the analysis indicate that current enforcement mechanisms have been relatively ineffective at increasing compliance and that some change either in enforcement or compliance standards is warranted. Additionally, a one‐size‐fits‐all enforcement approach is unlikely to be effective.     

Family Court Mediation: New Zealand Practices and Perspectives

Family separation is increasingly being dealt with by counsellors trained in the skills of mediation, along with skills of counselling and therapy. Other professionals also offer mediation services. In New Zealand, special provisions exist in the Family Court system to minimise the trauma for families by using mediation services, with the special opportunity for a couple to enter a Mediation Conference chaired by a Family Court Judge. It is argued that mediation is different from counselling and therapy, but that mediation requires many of the skills of counselling. This has particular consequences for training and for multidisciplinary teamwork.     

Recycling in multi-family dwellings: Increasing participation and decreasing contamination

This study explored the promotion of recycling in multi-family dwellings. An experimental design investigated four behavior change techniques: biweekly postcards giving specific feedback to each dwelling unit as to quantity and contamination of the recyclables, newsletters giving general information on recycling and the amount recycled by the city as a whole, written pledges committing households to recycle for a specified period, and volunteer coordinators who distributed information and answered questions from residents. The effectiveness of these techniques was compared against that of a control group. The findings suggest that volunteer coordinators are not an effective intervention technique in multi-family dwellings, and that feedback and commitment techniques are useful mainly for managing contamination in medium sized complexes. The data also suggest that the size of a multi-family dwelling complex significantly affects the amount of recyclables collected and the level of contamination. Smaller complexes with less than ten units recycled up to three times the amount on a per unit basis as complexes with more units. Smaller units also had fewer problems with contamination in their recyclables. Several explanations are offered for the poor participation and performance in larger complexes.
