Estimable Versions of Griffiths' Measure of Association

Many techniques have been proposed for measuring the degree of association between a pair of random variables X and Y. However, the measures often suffer from two drawbacks: they are difficult to calculate when the joint distribution of (X, Y) is known, and difficult to estimate when the joint distribution is unknown. In the present paper we present two modifications of a measure proposed by Griffiths (1972), and show that they exhibit neither of these deficiencies.     

A Probabilistic Model of the Economic Risk to Britain's Railway Network from Bridge Scour During Floods

Scour (localized erosion by water) is an important risk to bridges, and hence many infrastructure networks, around the world. In Britain, scour has caused the failure of railway bridges crossing rivers in more than 50 flood events. These events have been investigated in detail, providing a data set with which we develop and test a model to quantify scour risk. The risk analysis is formulated in terms of a generic, transferrable infrastructure network risk model. For some bridge failures, the severity of the causative flood was recorded or can be reconstructed. These data are combined with the background failure rate, and records of bridges that have not failed, to construct fragility curves that quantify the failure probability conditional on the severity of a flood event. The fragility curves generated are to some extent sensitive to the way in which these data are incorporated into the statistical analysis. The new fragility analysis is tested using flood events simulated from a spatial joint probability model for extreme river flows for all river gauging sites in Britain. The combined models appear robust in comparison with historical observations of the expected number of bridge failures in a flood event. The analysis is used to estimate the probability of single or multiple bridge failures in Britain's rail network. Combined with a model for passenger journey disruption in the event of bridge failure, we calculate a system‐wide estimate for the risk of scour failures in terms of passenger journey disruptions and associated economic costs.     

Accepting and Negotiating Service Users' Choices in Mental Health Transition Meetings

Across Western welfare regimes, policies emphasize that service users should have more choices regarding their services. This article examines how service choices are presented, responded to and decided in interactions between service users and professionals in mental health transition meetings. Choice is often associated with consumerist user involvement ideas, but in mental health choice also relates to the democratic user involvement approach and to shared decision making between professionals and service users. The results of the study show that professionals construct service users as consumers by offering service options in choice making sequences, expecting users to make appropriate choices. Service users mostly act like consumers by responding to these choice options. However, the study also demonstrates that the professionals do not always accept the user's first choice but respond to them as non‐preferred. Sometimes, they also suggest choices on behalf of the users. In these ‘non‐accepting’ sequences, choices are negotiated in interaction between the parties, rather than users acting as autonomous choice makers. The sequences are based on two kinds of professional reasoning: first, the professional‐led needs assessment and, second, the structure of the service package that the user is being offered. This negotiation has elements of shared decision making and the ‘logic of care’. But it also has elements of paternalist control which challenge both consumerist and democratic service user involvement and suggests consideration of more collectively oriented service user actions.     

Substance use and other factors associated with child welfare case duration: Looking beyond out of home care

Little is known about factors associated with child welfare case duration. Understanding factors associated with case duration may help stakeholders make more informed decisions about funding and service allocation and improve compliance with federal law. This study had two research questions: (1) What factors are associated with child welfare case duration? And (2) Do factors differ depending on whether children were placed exclusively with parents or with others (e.g. relatives and foster care) during the case? The study sample consisted of families (N = 874) with co-occurring child maltreatment and substance use in one midwestern state in the United States between 2007 and 2016. Linear regression models were used to identify correlates of case duration while controlling for child placement status. Overall, having a child under 1 year of age, benzodiazepine use, methamphetamine use and injection drug use were all associated with longer case duration, whereas marijuana use with no other substance use was associated with shorter case duration. Additionally, factors associated with case duration differed based on child placement status during the case. These findings suggest important heterogeneity in families involved with child welfare services and may allow for proactive mitigation of cases at greater risk.     

Notes on School-Based Crime Fighting: International Lessons in Moral Education

Few communities are immune to organized crime and corruption. What has not been fully explored is how education in lawfulness can be introduced into the curriculum of primary and secondary schools to confront the influences of criminal life styles that continue to be romanticized byfactions within a community. This paper reports on such efforts in Sicily, Hong Kong, Russia, and Mexico. Each community is vigorously seeking to repel negative influences from traditional strongholds of organized crime, which continue to exert powerful and pernicious effects on those societies.

Challenging organized crime requires more than governmental regulatory responses. Civic, business, labor, religious, social, and educational organizations all have a role in mitigating the scourge of lawlessness. A central question is to consider the ways in which a civil society can foster a culture of lawfulness. Promoting a set of beliefs and mobilizing the legal norms and institutions for changing, administering, and enforcing laws will enhance and protect “quality of life” is a task that some primary and secondary schools have begun to explore. One approach involves moral education, explicitly and directly teaching children and young people about the rewards and obligations in making moral and ethical decisions. This paper examines this effort in four, distinct cultural settings.     

Black women talk about stereotypical transference enactments in cross-cultural supervision

ABSTRACT

Little is known about cross-cultural supervision dynamics between Black, female supervisors who provide clinical supervision of White supervisees. This study examined transference enactments which occurred between Black, female clinical supervisors (N = 57) and White supervisees. The results show that White supervisees’ racist and sexist behaviors towards the Black, female supervisors demonstrated remnants of stereotypical images historically attributed to Black women (i.e., Mammy, Jezebel, and/or Sapphire). Moreover, the findings highlight the need to initiate multicultural awareness, knowledge, and skills to enhance clinical skills. The paper concludes with recommendations for cross-cultural supervisory dyads and implications for future research.
