The purpose of this paper is to assess changes in rates of mental health problems and service utilisation for Australian regular injecting drug users (IDUs) from 2006 to 2012.

Data were taken from Illicit Drug Reporting System national surveys with 914 regular IDUs in 2006 and 883 in 2012. Changes in rates of self-reported mental health problems and service use were assessed.

Rates of self-reported mental health problems increased from 38.3 per cent in 2006 to 43.7 per cent in 2012 – mainly due to increases in anxiety rates. Conversely, there was a decrease in mental health service use from 70.2 to 58.4 per cent by 2012. However, there was a proportional increase in the use of psychologists. These trends remained after controlling for socio-demographic and medical differences between the 2006/2012 samples. K10 scores for 2012 participants validated the use of the self-report measures.

Reductions in stigma, improvements in mental health literacy, and modest increases in anxiety may explain increases in self-report of mental health problems. Stagnant service utilisation rates in an expanding population willing to self-report may explain decreasing service use. The introduction of key mental health reforms also may have contributed, particularly with the increase in psychologist access. This paper highlights the need for improved population monitoring of mental health in disadvantaged groups such as IDUs.

This paper is the first to assess changes in mental health outcomes over time in Australian IDUs. This examination covered a critical era in the mental health landscape, with significant increases in public awareness campaigns and major mental health reforms.

This chapter compares interdisciplinary research that engages genomic science from economics, political science, and sociology. It describes, compares, and evaluates concepts and research findings from new and rapidly developing research fields, and develops a conceptual taxonomy of the social environment.

A selection of programmatic and empirical articles, published mostly since 2008 in leading economics, political science, and sociology journals, were analyzed according to (a) the relationship they pose between their discipline and genomic science, (b) the specific empirical contributions they make to disciplinary research questions, and (c) their conceptualization of the “social environment” as it informs the central problematique of current inquiry: gene-environment interaction.

While all three of the social science disciplines reviewed engage genomic science, economics and political science tend to engage genomics on its own terms, and develop genomic explanations of economic and political behavior. In contrast, sociologists develop arguments that for genomic science to advance, the “environment” in gene-environment interaction needs better theorization and measurement. We develop an approach to the environment that treats it as a set of measurable institutional (rule-like) arrangements, which take the forms of neighborhoods, families, schools, nations, states, and cultures.

Interdisciplinary research that combines insights from the social sciences and genomic science should develop and apply a richer array of concepts and measures if gene-environment research – including epigenetics – is to advance.

This chapter provides a critical review and redirection of three rapidly developing areas of interdisciplinary research on gene-environment interaction and epigenetics.

This article explores the contingent role that social ties play in the emergence of status hierarchies. We argue that, while status is formed based on actors’ perception and understanding of social cues, network structure, and position influence this process by influencing the attention and legitimacy given to the focal actor in accordance with social cues that signal an actor’s identity. Using a large data set from an open-source software development community, we find that a broker linking diverse network members is less likely to receive status ratings from others and that the rating is more likely to be low when a broker receives a rating. Furthermore, we find evidence that the effects of brokerage are contingent upon certain factors that may affect the attention and legitimacy given to actors in the process of status evaluation, such as the actor’s prior status. An actor’s prior status was found to weaken the negative effect of brokerage. The importance of this study for theories of status, social networks, and attention is discussed.

The authors theorize the role that identity, and especially collective identity, plays in the creation of new institutions. The authors begin by reviewing the literature on social movements, focusing on identity movements; from this, the authors extract and explore the role of identity in collective action and institutional formation. The authors propose that identity and lifestyle movements create institutions that furnish the necessary cultural tools to support and enact a given identity. As an example of this process, the authors examine Martha Stewart’s cultivation of a lifestyle-driven brand. The authors discuss the implications of their work on social movement theory and institutional theory.

This issue is a selected bibliography covering the subject of leadership.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.
