Electronic Cigarettes Regulation in the UK: A Case Study in Evidence Informed Policy Making
Full text linkThis chapter argues that policy debates on electronic cigarettes (e-cigarettes) are structured around competing evidence claims between proponents and sceptics, who remain bitterly divided on the issue. The confusion and intransigence which has emerged between these camps is, in part, the result of an insufficiently nuanced understanding of the value-centred and highly political nature of the policy process, and the highly circumscribed (yet nonetheless important) role which evidence can play within this. Key policy actors, often from biomedical backgrounds, or trained in the natural sciences, have been unable to recognise the limits of evidence to resolve protracted policy controversies such as that surrounding e-cigarettes. The chapter highlights the value of insights, derived from interpretative social science, about the multiple potential framings of an issue and the need for reflexivity on the part of policy actors to move beyond the current impasse
Using Evidence in a Highly Fragmented Legislature: The Case of Colombia's Health System Reform
Full text linkThis chapter examines how evidence is used in major policy health policy initiatives in a highly contested political context. Through a case study of legislation proposed in the context of Colombia’s ongoing health systems reformed process, it explores how such use is affected by the specific role played by the legislature within a highly fragmented polity. It draws on an analysis of evidence cited in the drafting of relevant laws in the process of health systems reform. Reflecting the role of the legislature in Colombia’s contested political system, evidence cited in legislative debates was unable to forge consensus amongst relevant policy actors over health system reforms. While scientific research was available and at the disposal of legislators, it was unable to provide the common ground on which to overcome embedded policy positions and form the basis of compromise over the direction of health systems reforms
Conclusion: Reflecting on Studying Evidence Use from a Public Policy Perspective
Full text linkThis final chapter reflects on the insights provided by the case studies that constitute this volume, focussing on the key questions which informed the broader research programme from which the cases arise: what does it mean to use evidence effectively to inform health policymaking?; and how do political and institutional factors shape the specific forms of evidence use that arise in different contexts? It discusses the circumstances in which instrumental or strategic uses of evidence were seen; as well as synthesising insights about the ways in which political contestation, the framing and construction of policy problems and their solutions, and different institutional arrangements for policy delivery shape evidence use in different policy contexts. The chapter concludes by considering future areas of research in this field to provide further insights into the use of evidence for health policymaking from a public policy perspective
Studying Evidence Use for Health Policymaking from a Policy Perspective
Full text linkIndividuals 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
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
