Interrogating conceptions of “vulnerable youth” in theory, policy and practice

Young people who are considered ‘vulnerable’ or ‘at risk’ are a particular target of various policies, schemes and interventions. But what does vulnerability mean? Interrogating Conceptions of “Vulnerable Youth” explores this question in relation to various policy fields that are relevant to young people, as well for how this plays out in practice and how it is experienced by young people themselves. What makes this book unique is that most authors had the opportunity to jointly explore these issues during a two-day workshop, and their chapters are informed by their cross-agency and cross-discipline discussions, making for a nuanced and thoughtful set of contributions. This collection is highly recommended for researchers and research students in the social sciences, as well as professional staff working in youth policy and youth services, in government departments and in NGOs. “Those who are most vulnerable should receive our greatest moral attention. However, the translation of generalised moral principles into effective policy and programs has never been easy. Political interests have invariably intervened, leading to complex debates about how vulnerability should be defined, classified, measured and represented. In recent years, these debates have become further complicated, as nation-states around the world have preached austerity. This timely book suggests that the responsibility for protecting the vulnerable cannot be left to individuals, but demands collective action, through institutions such as education, health and welfare. It examines some of the ways in which public policies and programs represent those who are vulnerable, involving a range of assumptions about the social, economic and political conditions that produce their vulnerabilities.” From the Foreword by Professor Fazal Rizvi

Towards a sociology of measurement in education policy

The Organisation for Economic Cooperation and Development (OECD) has developed impressive machinery to produce international comparative data across more than 70 systems of education and these data have come to be used extensively in policy circles around the world. In many countries, national and international comparative data are used as the bases for significant, high-stakes policy and reform decisions. This article traces how international comparability is produced, using the example of equity measurement in OECD's Programme for International Student Assessment (PISA). It focuses on the construction of the objects of comparison and traces the struggles to produce equivalence and commensurability across diverse and complex worlds. Based on conversations with a number of measurement experts who are familiar with the OECD and PISA, the article details how comparability is achieved and how it falters and fails. In performing such an analysis, this research is not concerned with ‘exposing’ the limitations of comparison or challenging their validity. Rather, based on the work of Steve Woolgar and other scholars, it attempts to mobilise a ‘sociology of measurement’ that explores the instrumentalism and performativity of the technologies of international comparisons.

The struggle to technicise in education policy

In contemporary education policy, simplified technical accounts of policy problems and solutions are being produced with the use of numeric calculations. These calculations are seen as clear and unbiased, capable of revealing ‘‘what works’’ and identifying ‘‘best practices.’’ In this piece, the authors use resources from the materialsemiotic approach of actor-network theory to discuss how calculations have begun to serve as a subtle infrastructure underpinning the way we understand and organise our world. They demonstrate the usefulness of the approach in tracing the technicisation of policy by deploying it to qualitative studies of like-school comparisons in the two unexpectedly linked locations—New York City and Australia. The authors reveal how technical accounts are precarious and need constant maintenance to endure, even as they increasingly becoming routine, curtailing the policy imagination and limiting the spaces of contestation. It is for this reason, they argue, that a deeper understanding and sustained critique of such accounts is of pressing importance.

Does gender moderate the subjective measurement and structural paths in behavioural and cognitive aspects of gambling disorder in treatment-seeking adults?

Introduction
Gender differences have been observed in the pathogenesis of gambling disorder and gambling related urge and cognitions are predictive of relapse to problem gambling. A better understanding of these mechanisms concurrently may help in the development of more directed therapies.
Methods
We evaluated gender effects on behavioural and cognitive paths to gambling disorder from self-report data. Participants (N = 454) were treatment-seeking problem gamblers on first presentation to a gambling therapy service between January 2012 and December 2014. We firstly investigated if aspects of gambling related urge, cognitions (interpretive bias and gambling expectancies) and gambling severity were more central to men than women. Subsequently, a full structural equation model tested if gender moderated behavioural and cognitive paths to gambling severity.
Results
Men (n = 280, mean age = 37.4 years, SD = 11.4) were significantly younger than women (n = 174, mean age = 48.7 years, SD = 12.9) (p < 0.001). There was no gender difference in conceptualising latent constructs of problem gambling severity, gambling related urge, interpretive bias and gambling expectancies. The paths for urge to gambling severity and interpretive bias to gambling severity were stronger for men than women and statistically significant (p < 0.001 and p = 0.004, respectively) whilst insignificant for women (p = 0.164 and p = 0.149, respectively). Structural paths for gambling expectancies to gambling severity were insignificant for both men and women.
Conclusion
This study detected an important signal in terms of theoretical mechanisms to explaining gambling disorder and gender differences. It has implications for treatment development including relapse prevention.

Simulation of oleuropein structural conformation in vacuum, water and triolein-water systems using molecular dynamics

Oleuropein, the main phenolic compound of olive leaves, exhibits a unique blend of biological activities and has been shown to locate itself at the oil-water (O/W) interface. This behavior could influence the physico-chemical properties of dispersed systems such as emulsions. In this work, we study the effect of the microenvironment (vacuum, water, and triolein-water) on the conformational preferences of oleuropein using molecular dynamics (MD) simulations at 300K for at least 30ns. The seven torsions that describe the flexible skeleton of oleuropein were monitored together with the distance between the glucose (Glu) and hydroxytyrosol (Hyd) moieties (dglu-hyd) of the molecule. The obtained trajectories demonstrated that oleuropein adopts different conformations that depend on the environment. The preferential conformers in each system were analyzed for their molecular geometry and internal energy. In vacuum, the oleuropein preferential conformation is tight with the glucose moiety in close proximity with the hydroxytyrosol moiety. In water, oleuropein preferential conformers presented large differences in their structural properties, varying from a close like U form, and a semi-opened form, to an opened form characterized by high fluctuations in dglu-hyd values. In a triolein-water system, oleuropein tends to adopt a more open form where the glucose moiety could be approximately aligned with the hydroxytyrosol and elenolic acid moieties. Based on a calculation at the HF/6-31G* level, these flexibilities of oleuropein required energy of 19.14kcal/mol in order to adopt the conformation between water and triolein-water system. A radial distribution function (RDF) analysis showed that specific hydroxyl groups of Hyd and Glu interact with water molecules, enabling us to understand the amphiphilic character of oleuropein at the triolein-water interface. MD calculations together with interfacial tension measurements revealed that the oleuropein binding at O/W interface is an enthalpy driven mechanism.

ICES meets marine historical ecology: placing the history of fish and fisheries in current policy context

As a discipline, marine historical ecology (MHE) has contributed significantly to our understanding of the past state of the marine environment when levels of human impact were often very different from those today.What is less widely known is that insights from MHE have made headway into being applied within the context of present-day and long-term management and policy. This study draws attention to the applied value of MHE. We demonstrate that a broad knowledge base exists with potential for management application and advice, including the development of baselines and reference levels.Using a number of case studies from around the world,we showcase the value of historical ecology in understanding change and emphasize how it either has already informed management or has the potential to do so soon.We discuss these case studies in a context of the science–policy interface around six themes that are frequently targeted by current marine and maritime policies: climate change, biodiversity conservation, ecosystem structure, habitat integrity, food security, and human governance.We encourage science–policy bodies to actively engage with contributions from MHE, as well informed policy decisions need to be framed within the context of historical reference points and past resource or ecosystem changes.

New evidence on purchasing power parity from 17 OECD countries

There is a large literature that investigates whether or not real exchange rates are stationary in an attempt to unravel support for purchasing power parity (PPP). At best, the empirical results are mixed. This paper applies a unit root test that allows for a simultaneous structural break in the intercept and slope, shown by Sen (2003) to minimize power distortions, to examine PPP for 17 OECD countries. Our results on PPP are mixed. When the real exchange rate is based on the US dollar, evidence is found of PPP for only France, Portugal and Denmark. When the real exchange rate is based on the Deutschmark, we find evidence of PPP for Austria, Belgium, Norway, Spain, Netherlands, Switzerland, and Denmark.

A nonlinear approach to testing the unit root null hypothesis : an application to international health expenditures

In this article, we examine the unit root null hypothesis for per capita total Health Expenditures (HEs), per capita private HEs and per capita public HEs for 29 Organization for Economic Co-operation and Development (OECD) countries. The novelty of our work is that we use a new nonlinear unit root test that allows for one structural break in the data series. We find that for around 45% of the countries, we are able to reject the unit root hypothesis for each of the three HE series. Moreover, using Monte Carlo simulations, we show that our proposed unit root model has better size and power properties than the widely used Augmented Dickey–Fuller (ADF) and Lagrange Multiplier (LM) type tests.

Impacts of monetary policies on housing affordability in Australia

Housing affordability has become a major policy issue in many countries across the world since the rapid inflation of house prices. This paper empirically investigates how monetary policies affect housing affordability in Australia from 1998 to 2009. Three primary variables associated with the housing sector and monetary policy, which are money supply, interest rates and house prices, are studied for all eight capital cities in Australia in this research. Shocks of such variables are identified by a structural vector autoregression (SVAR) model with restrictions that are consistent with economic theoretical framework. Based upon the analysis using the structural decomposition of impulse response on quarterly data, it can be discovered that the monetary policy plays an active role in housing affordability via adjustments of money supply and interest rates during the observed period in Australia. The empirical results from this research may be used for decision makers to determine money supply and interest rates from the perspective of housing affordability.

Cervical cancer services for Indigenous Women: Advocacy, Community-Based Research and Policy Change in Australia

Collaborative research undertaken in the state of Queensland, Australia, resulted in major changes in cervical cancer screening and treatment for Indigenous women. Guided by an Indigenous statewide reference group and with an Indigenous researcher playing a lead role, qualitative data were collected using interviews, focus groups, and larger community meetings; and case studies were conducted with health workers and community members from diverse rural, remote and urban communities, to explore the different cultural and structural factors affecting understanding and awareness of cervical cancer and Indigenous women's use of and access to health services for screening, diagnosis and treatment. These data were supplemented by an analysis of clinical data and health service checklists. We discuss the methodology and summarize the key social and structural factors that discourage women from presenting for screening or returning for follow-up. These include women's misunderstanding of cervical cancer screening, fear of cancer, distrust of health services, poor recall and follow-up systems, and the economic and social burden to women presenting for treatment. We describe how the research process and subsequent activities provided Indigenous women with a vehicle for their own advocacy, resulting in important policy and program changes.
