Meta-analysis of risk factors for canine leptospirosis
No full textLeptospirosis is one of the most widespread zoonotic diseases, with more than one million human cases reported worldwide every year. Dogs could develop infections that range from asymptomatic to severe, and shed leptospires with their urine. Given their close contact with humans, dogs may act both as epidemiological links or as sentinels of pathogenic leptospires in the environment. The aims of our study were to quantitatively summarize the overall prevalence of leptospiral antibodies and to identify factors associated with the probabilities of infection. We searched the electronic databases Scopus, PubMed, PMC and ScienceDirect for observational studies on canine leptospirosis published between 1989 and December 2019 and written in English, Spanish or Portuguese. We fitted a series of multilevel random effects meta-analysis models to estimate the prevalence of antibodies against Leptospira for different types of dogs, health statuses, diagnostic tests, geographic regions and income categories of the countries. We also fitted a number of random effects meta-analysis models to estimate the pooled odds-ratio of factors associated with canine leptospirosis. After removing duplicates and articles not meeting selection criteria, a total of 130 studies in 91 articles were included in this work. We found lower seroprevalence estimates in North America countries () and other high income countries (). We also found higher probabilities of leptospiral infection in adult (), male dogs with access to the streets (). Identifying the profile of dogs that are more exposed to leptospirosis could be useful in the design of public health strategies for the prevention and control of leptospirosis.EEA RafaelaFil: Ricardo, Tamara.

Córdoba, Argentina.La disposición de desperdicios provenientes de la actividad clínica puede tener un impacto en el ambiente, la salud animal y pública. No obstante, se han desarrollado pocos estudios en América Latina sobre la dimensión del problema de descarte inapropiado de jeringas, agujas, envases de medicinas y otros insumos médicos. El objetivo de este trabajo fue describir las formas de disposición de insumos veterinarios utilizados en el ámbito rural y los factores asociados a su descarte en áreas urbanas. Se efectuó un estudio transversal en 421 veterinarios que trabajaban con grandes animales en la provincia de Santa Fe, Argentina, utilizando un cuestionario estructurado. El análisis estadístico incluyó χ2 y regresión logística. Los resultados indican que menos del 50% de los entrevistados embolsaba los insumos usados y una minoría lo hacía por separado de acuerdo al tipo de insumo. Residuos potencialmente peligrosos eran entregados al personal de campo para su posterior descarte. Los profesionales de mayor edad y quienes también trabajaban con pequeñas especies tuvieron respectivamente 1,3 y 1,5 veces más riesgo de descartar en áreas urbanas los desperdicios de insumos usados en el campo. Por el contrario, quienes tenían su residencia laboral en la región centro de la provincia tuvieron una probabilidad significativamente menor. Solo uno de cada cinco entrevistados contaba, en su localidad de residencia, con disponibilidad de transporte de residuos peligrosos autorizado. Solo del 3 al 5% de los encuestados descartaba los insumos como residuos patológicos. La estrecha relación existente entre el campo y la ciudad dentro de un mismo territorio pone en riesgo la salud pública de los centros urbanos tanto por el descarte de insumos como por el movimiento de personas de un espacio a otro dentro del mismo territorio.tbls., grafs
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

We also found higher probabilities of leptospiral infection in adult (P=0.017), male dogs with access to the streets (P<0.001).

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
