College campus smoking policies and programs and students' smoking behaviors

BACKGROUND: Although tobacco use in the United States has declined over the past 20 years, cigarette use among college students remains high. Additional research is thus needed to determine how university tobacco control policies and preventive education programs affect college students' smoking behaviors. METHODS: Approximately 13,000 undergraduate students at 12 universities or colleges in the state of Texas completed a web-based survey. College smoking policies were obtained from a survey of college administrators and from college websites. Logistic regression analyses were conducted to estimate the effects of individual smoking policies and programs on the odds of cigarette smoking. RESULTS: Of the individual programs, only having a preventive education program on campus was associated with lower odds of smoking. The existence of smoking cessation programs and designated smoking areas were associated with higher odds of smoking. Policies governing the sale and distribution of cigarettes were insignificantly associated with smoking. CONCLUSION: Rather than focusing on policies restricting cigarette sales and use, college administrators should consider implementing or expanding tobacco prevention and education programs to further reduce student smoking rates

What is an "adult protection" issue? Victims, perpetrators and the professional construction of adult protection issues

Drawing on data from a Scottish research study, this paper explores the relationship of professionals’ perceptions about specific perpetrators and victims to their constructions of ‘adult protection’ issues in practice. It finds that professionals’ perceptions of victim distress did not consistently coincide with the construction of adult protection issues, whilst the connection to any assessment of victims’ heightened vulnerability in specific cases was not clear. With respect to perpetrators, implicit practice rules were evidenced which differed from explicit policy criteria. In particular, there were different rules for relatives, staff and service user perpetrators, whilst harms attributed to institutions were de-emphasized. Explanations of the findings are advanced based on the complex power relations underpinning practice but unacknowledged in policies. More research is recommended to deepen this analysis in a changing policy context, to foreground service user perspectives, and to contextualize harms potentially resolvable through adult support and protection/safeguarding routes with respect to harms better addressed in other ways

Clusters of galaxies : observational properties of the diffuse radio emission

Clusters of galaxies, as the largest virialized systems in the Universe, are ideal laboratories to study the formation and evolution of cosmic structures...(abridged)... Most of the detailed knowledge of galaxy clusters has been obtained in recent years from the study of ICM through X-ray Astronomy. At the same time, radio observations have proved that the ICM is mixed with non-thermal components, i.e. highly relativistic particles and large-scale magnetic fields, detected through their synchrotron emission. The knowledge of the properties of these non-thermal ICM components has increased significantly, owing to sensitive radio images and to the development of theoretical models. Diffuse synchrotron radio emission in the central and peripheral cluster regions has been found in many clusters. Moreover large-scale magnetic fields appear to be present in all galaxy clusters, as derived from Rotation Measure (RM) studies. Non-thermal components are linked to the cluster X-ray properties, and to the cluster evolutionary stage, and are crucial for a comprehensive physical description of the intracluster medium. They play an important role in the cluster formation and evolution. We review here the observational properties of diffuse non-thermal sources detected in galaxy clusters: halos, relics and mini-halos. We discuss their classification and properties. We report published results up to date and obtain and discuss statistical properties. We present the properties of large-scale magnetic fields in clusters and in even larger structures: filaments connecting galaxy clusters. We summarize the current models of the origin of these cluster components, and outline the improvements that are expected in this area from future developments thanks to the new generation of radio telescopes.Comment: Accepted for the publication in The Astronomy and Astrophysics Review. 58 pages, 26 figure

What Counts as ‘World Class’? : Global University Rankings and Shifts in Institutional Strategies

Global university rankings have emerged as a benchmark of institutional success, setting standards for higher education policymaking and institutional practices. Nevertheless, only a marginal share of higher education institutions (HEI) are in a realistic position to be ranked as a ‘world-class’ institutions. In the European context, the global rankings have been used to highlight a performance gap between European and North American institutions. Here the focus has been on the HEIs in the top-100 positions, causing concerns over European higher education. This has also become a marker of world-class university. We analyze the strategies of 27 Northern European universities in different tiers to learn how they have adjusted to the reality of ranking. We conclude that the references to global rankings have increased between 2014 and 2018. At the same time, the references to rankings have become more implicit in nature. Nevertheless, we find that the discourse of global comparison and excellence has become more common in the strategies. There are also emerging references to the regional role of universities, which are apparent in the strategies of universities that are clearly outside the top-100 ranked institutions. However, this is also a reflection of the discourse of world-class university.Peer reviewe

Appeals to evidence for the resolution of wicked problems: the origins and mechanisms of evidentiary bias

Wicked policy problems are often said to be characterized by their ‘intractability’, whereby appeals to evidence are unable to provide policy resolution. Advocates for ‘Evidence Based Policy’ (EBP) often lament these situations as representing the misuse of evidence for strategic ends, while critical policy studies authors counter that policy decisions are fundamentally about competing values, with the (blind) embrace of technical evidence depoliticizing political decisions. This paper aims to help resolve these conflicts and, in doing so, consider how to address this particular feature of problem wickedness. Specifically the paper delineates two forms of evidentiary bias that drive intractability, each of which is reflected by contrasting positions in the EBP debates: ‘technical bias’ - referring to invalid uses of evidence; and ‘issue bias’ - referring to how pieces of evidence direct policy agendas to particular concerns. Drawing on the fields of policy studies and cognitive psychology, the paper explores the ways in which competing interests and values manifest in these forms of bias, and shape evidence utilization through different mechanisms. The paper presents a conceptual framework reflecting on how the nature of policy problems in terms of their complexity, contestation, and polarization can help identify the potential origins and mechanisms of evidentiary bias leading to intractability in some wicked policy debates. The discussion reflects on whether being better informed about such mechanisms permit future work that may lead to strategies to mitigate or overcome such intractability in the future

Studying Evidence Use for Health Policymaking from a Policy Perspective

Individuals working within the health sector widely embrace the idea of using evidence to achieve their goals of improving individual and population health. Yet while these actors embrace an ideal form of rational-instrumental evidence use under the banner of ‘evidence based policymaking’, they often struggle to understand when, why, or how evidence is used in policy processes. This chapter sets out the conceptual framework employed in this volume to study the use of evidence within policymaking from a public policy perspective. It explores the importance of both political contestation and institutional context to understand when and how evidence will be used within policy processes. The chapter then outlines the structure of this book and the focus of subsequent chapters, highlighting how each of these talks to these themes

The many meanings of evidence: a comparative analysis of the forms and roles of evidence within three health policy processes in Cambodia

Background Discussions within the health community routinely emphasise the importance of evidence in informing policy formulation and implementation. Much of the support for the evidence-based policy movement draws from concern that policy decisions are often based on inadequate engagement with high-quality evidence. In many such discussions, evidence is treated as differing only in quality, and assumed to improve decisions if it can only be used more. In contrast, political science scholars have described this as an overly simplistic view of the policy-making process, noting that research ‘use’ can mean a variety of things and rely on nuanced aspects of political systems. An approach more in recognition of how policy-making systems operate in practice can be to consider how institutions and ideas influence which pieces of evidence appear to be relevant for, and are used within, different policy processes. Methods Drawing on in-depth interviews undertaken in 2015/16 with key health sector stakeholders in Cambodia, we investigate the evidence perceived to be relevant to policy decisions for three contrasting health policy examples – tobacco control, HIV/AIDS and performance-based salary incentives. These cases allow us to examine the ways that policy relevant evidence may differ given the framing of the issue and the broader institutional context in which evidence is considered. Results The three health issues show few similarities in how pieces of evidence were used in various aspects of policy-making, despite all being discussed within a broad policy environment in which evidence-based policymaking is rhetorically championed. Instead, we find that evidence use can be better understood by mapping how these health policy issues differ in terms of the issue characteristics, and also in terms of the stakeholders structurally established as having dominant influence for each issue. Both of these have important implications for evidence use. Contrasting concerns of key stakeholders meant that evidence related to differing issues could be understood in terms of how it was policy relevant. The stakeholders involved, however, could further be seen to possess differing logics about how to go about achieving their various outcomes – logics that could further help explain the differences seen in evidence utilisation. Conclusion A comparative approach reiterates that evidence is not a uniform concept for which more is obviously better, but rather illustrates how different constructions and pieces of evidence become relevant in relation to the features of specific health policy decisions. An institutional approach that considers the structural position of stakeholders with differing core goals or objectives, as well as their logics related to evidence utilisation, can further help to understand some of the complexities of evidence use in health policymaking
