    Do household surveys give a coherent view of disability benefit targeting? A multi-survey latent variable analysis for the older population in Great Britain

    Full text link
    We compare three major UK surveys, BHPS, FRS and ELSA, in terms of the picture they give of the relationship between disability and receipt of the Attendance Allowance (AA) benefit. Using the different disability indicators available in each survey, we estimate a model in which probabilities of receiving AA depend on latent disability status. Despite major differences in design, once sample composition is standardised through statistical matching, the surveys deliver similar results for the model of disability incidence and AA receipt. Provided surveys offer a sufficiently wide range of disability indicators, the detail of disability measurement appears relatively unimportant

    We compare three major UK surveys, BHPS, FRS and ELSA, in terms of the picture they give of the relationship between disability and receipt of the Attendance Allowance (AA) benefit. Using the different disability indicators available in each survey, we use a structural equation approach involving a latent concept of disability in which probabilities of receiving AA depend on disability. Despite major differences in design, once sample composition is standardised through statistical matching, the surveys deliver similar results for the model of disability and AA receipt. Provided surveys offer a sufficiently wide range of disability indicators, the detail of disability measurement appears relatively unimportant

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    Can production and trafficking of illicit drugs be reduced or merely shifted ?

    The production of cocaine and heroin, the two most important drugs economically, has been concentrated in a small number of poor nations for 25 years. A slightly larger number of developing nations have been affected by large-scale trafficking in these two drugs. This paper reviews what is known about drug control programs and considers non-traditional options. The usual array of programs for suppressing drug problems, enforcement, treatment, harm reduction and prevention have been assessed almost exclusively in wealthy nations. Although treatment has been shown to be cost-effective, it is of minimal relevance for reducing the drug problems of nations such as Afghanistan, Colombia, Mexico or Tajikistan, which are primarily harmed by production and trafficking rather than consumption. Efforts to reduce drug production and trafficking have not been subject to systematic evaluation but the best interpretation of the available evidence is that they have had minimal effect on the quantities produced or trafficked. It is reasonable to conclude that international drug control efforts can do more to affect where these drugs are produced rather than the quantity. If that is the case, and given that spreading a specific level of production or trafficking to more rather than fewer nations probably decreases global welfare, it may be appropriate to consider a less aggressive stance to current producers and to make strategic decisions about the location of an industry producing a global bad.Crime and Society,Economic Theory&Research,Markets and Market Access,Alcohol and Substance Abuse,Post Conflict Reconstruction

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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
