Are gamblers more likely to commit crimes? An empirical analysis of a nationally representative survey of US young adults

We examine the relationship between gambling and criminal behaviour using data from the National Longitudinal Study of Adolescent Health (Add Health). Our data set includes survey responses from 6145 young adults. The results of our empirical analysis are consistent with the gambling literature in which it is suggested that higher gambling losses increase the propensity to commit crime. This study complements the current literature, as our data and empirical analysis allow us to control for many variables that have been neglected in previous studies, including various forms of gambling. Our findings provide useful information on the general relationship between gambling behaviour and criminal behaviour.     

TECHNICAL AND INSTITUTIONAL STATES: Loose Coupling in the Human Rights Sector of the World Polity

While human rights treaties have become increasingly popular over the past quarter century, there has not been a corresponding improvement in human rights practices. This discrepancy implies that a country's formal pledge to uphold human rights principles is "loosely coupled" from its actual performance. In this study, I develop a model of loose coupling based on organizational research and apply it to the human rights sector of the world polity. Empirically, I identify a set of institutional states whose human rights practices fall short of their treaty commitments, as well as a set of technical states whose practices exceed their commitments. Analyzing an unbalanced data set with a maximum of 755 observations across 167 countries during the 1975 to 2000 period, I use random effects models to predict a state's location on the Human Rights Decoupling Index (HRDI). The findings illustrate the importance of several organizational concepts for predicting a state's HRDI score. In particular, the analyses reveal the countervailing effects of globalization. While economic globalization (i.e., trade and foreign investment) is associated with the technical (positive) end of the HRDI, cultural globalization (i.e., memberships in international organizations) is associated with the institutional (negative) end.     

Family Ties and Young Fathers' Engagement in Cape Town,South Africa

Young South African fathers are often engaged in their children's lives even if they do not live together. Using longitudinal data on children (n = 1,209) from the Cape Town area, the authors show that although only 26% of young fathers live with their children, 66% of nonresidential fathers maintain regular contact, and 61% provide financial support. The father–child relationship, however, is embedded in broader family ties. The type of father–mother relationship is strongly associated with whether fathers coreside with their children but not with fathers' contact with nonresidential children. Close mother and maternal grandmother bonds reduce the likelihood that fathers live with their children, whereas close ties between fathers and paternal grandmothers increase the chance that fathers visit nonresidential children. Family ties do not affect fathers' financial contributions, which are driven by men's current economic situation. These findings illustrate that father–child relationships are best understood in the context of interacting family systems.     

Slippery discrimination: a review of the drivers of migrant and minority housing disadvantage

ABSTRACT

This paper aims to identify housing disadvantages faced by migrants and ethnic minorities; the legal, policy and market forces that shape them; how they have developed over time; how they are manifest nationally and locally; and how they are being responded to locally by those concerned with mitigating them. The paper thereby intends to provide a foundation to inform future research and policy and to engage with local actors to develop ways of overcoming migrant housing disadvantage and challenging discrimination. The paper finds that the interplay of legal changes, which have increasingly differentiated migrants since the 1940s, and shifting housing markets, has driven exclusion of migrants and minorities such that considerable disadvantage is revealed by analysis of census data. However, attention to local specificity provides evidence of positive responses. Examples are presented in relation to access to affordable housing, enactment of homelessness duties and community actions. Methodologically, this paper highlights the importance of simultaneous consideration of migration and ethnicity as markers of difference and exclusion, and the potential of co-production approaches for socially meaningful research concerned with inequalities.     

Integrating the older/special needs adoptive child into the family

This qualitative, grounded theory study investigated 11 families who reported having successfully integrated into their family unit at least one older/special needs adoptee. The theory that emerged through the constant comparative methodology consisted of two categories (Decision to Adopt and Adjustment) and a core category (Developing a Sense of Family). The two categories and core category comprised a process that was informed by the Family Narrative Paradigm and culminated in the successful integration of the child or children into the existing family unit. Parental perceptions that appeared to facilitate this process included: (a) finding strengths in the children overlooked by previous caregivers, (b) viewing behavior in context, (c) reframing negative behavior, and (d) attributing improvement in behavior to parenting efforts.     

A hierarchical Bayesian model for predicting the functional consequences of amino-acid polymorphisms

Summary.  Genetic polymorphisms in deoxyribonucleic acid coding regions may have a phenotypic effect on the carrier, e.g. by influencing susceptibility to disease. Detection of deleterious mutations via association studies is hampered by the large number of candidate sites; therefore methods are needed to narrow down the search to the most promising sites. For this, a possible approach is to use structural and sequence-based information of the encoded protein to predict whether a mutation at a particular site is likely to disrupt the functionality of the protein itself. We propose a hierarchical Bayesian multivariate adaptive regression spline (BMARS) model for supervised learning in this context and assess its predictive performance by using data from mutagenesis experiments on lac repressor and lysozyme proteins. In these experiments, about 12 amino-acid substitutions were performed at each native amino-acid position and the effect on protein functionality was assessed. The training data thus consist of repeated observations at each position, which the hierarchical framework is needed to account for. The model is trained on the lac repressor data and tested on the lysozyme mutations and vice versa. In particular, we show that the hierarchical BMARS model, by allowing for the clustered nature of the data, yields lower out-of-sample misclassification rates compared with both a BMARS and a frequen-tist MARS model, a support vector machine classifier and an optimally pruned classification tree.     

Decision‐making in a phase II clinical trial: a new approach combining Bayesian and frequentist concepts

The aim of a phase II clinical trial is to decide whether or not to develop an experimental therapy further through phase III clinical evaluation. In this paper, we present a Bayesian approach to the phase II trial, although we assume that subsequent phase III clinical trials will have standard frequentist analyses. The decision whether to conduct the phase III trial is based on the posterior predictive probability of a significant result being obtained. This fusion of Bayesian and frequentist techniques accepts the current paradigm for expressing objective evidence of therapeutic value, while optimizing the form of the phase II investigation that leads to it. By using prior information, we can assess whether a phase II study is needed at all, and how much or what sort of evidence is required. The proposed approach is illustrated by the design of a phase II clinical trial of a multi‐drug resistance modulator used in combination with standard chemotherapy in the treatment of metastatic breast cancer.
