    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

    The hazards and risks of sewage clearing should be studied in order to reduce the possibility of occupational accidents in this function. Aiming at such analysis, the present study used strategies (field inspections, questionnaire application and PRA matrix assembly) to identify and classify the hazards and risks of this function, using as a case study a basic sanitation enterprise from Florianópolis, Santa Catarina. In short, ten risks of different natures (physical, chemical, biological, ergonomic and accident) were identified, with severity ranging from minor to critical. For each of the risks, preventive and corrective measures were indicated that the enterprise can use in order to establish a healthier and safer work routine. The measures include training, the adoption of administrative measures, the exchange of equipment and the use of appropriate PPE for the job. At the same time, it is noteworthy that the results obtained in the PRA matrix can also be used in the elaboration of a PPRA and a Risk Map, requested by NR-9 and NR-5, respectively.Os perigos e os riscos existentes na desobstrução de redes de esgoto devem ser estudados para que se diminua a possibilidade de acidentes do trabalho nessa função. Visando tal análise, no presente estudo foram utilizadas estratégias (inspeções de campo, aplicação de questionário e montagem de matriz de APR) para identificar e classificar os perigos e riscos dessa atividade, utilizando de base uma empresa de saneamento básico de Florianópolis, Santa Catarina. Em resumo, foram identificados dez riscos, de distintas naturezas (físicos, químicos, biológicos, ergonômicos e de acidentes), com gravidade variando entre menor e crítico. Para cada um dos riscos, foram indicadas medidas preventivas e corretivas que a empresa pode utilizar visando à instauração de uma rotina de trabalho mais saudável e segura. Dentre as medidas, cita-se a realização de treinamentos, a adoção de medidas administrativas, a troca de equipamentos e a utilização de EPI adequado para a função. Paralelamente, ressalta-se que os resultados obtidos na matriz de APR também podem ser aproveitados na elaboração de um PPRA e de um Mapa de Riscos, solicitados pela NR-9 e NR-5, respectivamente

    Solid waste production grows every year in Brazil and in most countries in the world, where society has high consumption standards and no sustainable bases. The management of municipal solid waste thus becomes a matter of public health today, due to its potential risks, not only arising from the large quantity produced and the possible inadequate disposition of this material in nature, but also on the on the health of human beings who carry out their management. Statistics indicate that the rate of solid waste production in Brazil exceeded the population growth rate in 2017, which highlights the increasing need for labor to act on solid waste management. One of the main and primary management activities is the collection of municipal solid waste, an activity that due to primary contact with waste is permeated by risks of the most varied: physical, chemical, biological, ergonomic, accidents and psychosocial. Thus it is necessary to know the accident statistics involving the activity and also the description of the main risks to which these workers are exposed so that appropriate actions can be taken to promote the safety and health of these workers.A produção de resíduos sólidos cresce a cada ano no Brasil e na maior parte dos países do mundo, onde a sociedade apresenta padrões de consumo elevados e sem bases sustentáveis. A gestão dos resíduos sólidos urbanos torna-se assim questão de saúde pública da atualidade, devido aos seus riscos em potencial, não somente advindos da grande quantidade produzida e da possível disposição inadequada desse material na natureza, mas também sobre a sobre a saúde dos seres humanos que realizam seu manejo. Estatísticas apontam que a taxa de produção de resíduos sólidos no Brasil chegou a superar a taxa de crescimento populacional em 2017, o que evidencia a necessidade cada vez maior de mão-de-obra para atuar do gerenciamento dos resíduos sólidos. Uma das principais e primordiais atividades do gerenciamento é a coleta dos resíduos sólidos urbanos, atividade esta que devido ao contato primário com os resíduos é permeada de riscos dos mais variados: físicos, químicos, biológicos, ergonômicos, de acidentes e psicossociais. Desta forma é necessário conhecer as estatísticas de acidentes envolvendo a atividade e também a descrição dos principais riscos a que estão expostos estes trabalhadores para que se possam tomar medidas cabíveis para a promoção da segurança e saúde destes trabalhadores

    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

    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

    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

    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
