    ‘All data is credit data’: personalised consumer credit scores and anti-discrimination law

    No full text
    Credit-score models provide one of the many contexts through which the big data micro-segmentation or ‘personalisation’ phenomenon can be analysed and critiqued. This chapter approaches the issue through the lens of anti-discrimination law, and in particular the concept of indirect discrimination. The argument presented is that, despite its initial promise based on its focus on impact, ‘indirect discrimination’ is after all unlikely to deliver a mechanism to intervene and curb the excesses of the personalised service model. The reason for its failure does not lie in its inherent weaknesses but rather in the 'shortcomings' (entrenched biases) of empirical reality itself which any 'accurate' (or useful) statistical analysis cannot but reflect. Still, the anti-discrimination context offers insights that are valuable beyond its own disciplinary boundaries. For example, the opportunities for oversight and review based on correlations within outputs rather than analysis of inputs is fundamentally at odds with the current trend that demands greater transparency of AI but may after all be more practical and realistic considering the ‘natural’ opacity of learning algorithms and businesses’ ‘natural’ secrecy. The credit risk score context also provides a low-key yet powerful illustration of the oppressive potential of a world in which individual behaviour from ANY sphere or domain may be used for ANY purpose; where a bank, insurance company, employer, health care provider, or indeed any government authority can tap into our social DNA to pre-judge us, should it be considered appropriate and necessary for their manifold objectives

    Análisis morfológico y molecular de aislamientos de Septoria glycines provenientes de hojas de soja de distintas localidades de la provincia de Buenos Aires

    La mancha marrón, una enfermedad de las llamadas de fin de ciclo en soja, es causada por el hongo Septoria glycines y es una de las enfermedades que provoca importantes pérdidas en la producción del cultivo. Si bien dicho patógeno puede ser controlado mediante la aplicación de fungicidas foliares, éstos tienen una acción limitada. La caracterización morfológica y molecular del hongo permite obtener un mayor conocimiento de éste y de la enfermedad que genera para poder lograr un manejo agronómico más eficiente, con los consiguientes beneficios económicos para el país, ya que la enfermedad causada por S. glycines puede provocar la pérdida total de la producción de un lote de soja. El objetivo del presente trabajo fue analizar morfológica y molecularmente los aislamientos de S. glycines provenientes de hojas de plantas de soja obtenidas a partir de relevamientos realizados en diferentes localidades de la región norte y centro de la provincia de Buenos Aires. Para la caracterización morfológica se tuvieron en cuenta caracteres cualitativos como color y densidad del micelio de las colonias incubadas por 15 días luego de haber sido obtenidas bajo cámara de flujo laminar, como así también caracteres cuantitativos como diámetro de la colonia y relación longitud/ancho (R L/A) de los conidios producidos por las mismas. La caracterización molecular se llevó a cabo a partir de secuenciación de productos de amplificación de actina (act) y de los espaciadores transcriptos internos (ITS) obtenidos de ADN genómico. En este trabajo no se encontraron evidencias de que en la región norte y centro de la provincia de Buenos Aires haya presencia de otra especie como agente etiológico de la mancha marrón en las plantas de soja, por lo tanto, Septoria glycines sería el único patógeno responsable de dicha enfermedad, hasta el momento.Fil: Rodriguez, Noelia Giselle.

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
