Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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

The research involves an automaker, two first tier suppliers and two second tier suppliers and it has been conducted through interviews with executives of those companies involved with the logistics, purchases and production areas. The study shows mainly that the recent structural changes within the Brazilian Automotive Industry have implicated directly in the coordination forms and innovations in the Supply Chain Management
Reference architecture for the formation and management of cooperation networks and innovation among the management integrated systems implementation agents
No full textA adoção de soluções integradas em processos organizacionais movimenta um crescente e importante setor da economia. Os sistemas integrados de gestão representam essas soluções e tornaram-se práticas usuais implantá-los como promessa de atendimento à demanda e às necessidades das empresas que buscam diferenciais competitivos. Como apoio a esse complexo processo, o trabalho propõe uma arquitetura de referência para a formação e gerência de redes de cooperação e inovação entre agentes de implantação de sistemas integrados de gestão. A revisão da literatura abarca temas essenciais ao sucesso da implantação do sistema integrado de gestão, que precisam compor o conhecimento do corpo da rede de agentes que serão responsáveis pela implantação. A abordagem se inicia na análise, nas formas de organização e coordenação do processo de produção. A bibliografia conceitua também a inovação, a cooperação e a formação e a gerência de redes. Um recorte analítico de redes é feito para um gênero de sistemas integrados de gestão, o ERP e uma discussão da aplicação direta da teoria de arquiteturas de referência. Três pilares sustentam e caracterizam o método de pesquisa. O primeiro é a revisão bibliográfica. O segundo é o estudo de caso, que confere caráter empírico à pesquisa. O terceiro é a metodologia de modelagem organizacional EKD que fornece as diretrizes construtivas da arquitetura de referência. A contribuição da pesquisa é que a arquitetura de referência propicie à empresa que implanta um sistema integrado de gestão, a criação de um mecanismo de proteção ao processo organizacional a ser integrado. Além disso, a arquitetura de referência promove a sistematização da coordenação dos recursos da implantação da solução, com maior certeza de probabilidade de sucesso.The adoption of integrated solutions in organized processes puts into motion an increasing and important sector of the economy. The management integrated systems (MIS) represent these solutions and it has become usual to implant them as attendance promise to the demand and the necessities of the companies who search for competitive differentials. As support to this complex process, the work considers reference architecture for the formation and management of cooperation networks and innovation among the MIS implementation agents. The literature review accumulates essential subjects for the application success of the integrated system which are requested to compose the knowledge of the body which integrates the net agents who will be responsible for the implementation. The approach gets started in the analysis, in the forms of organization and coordination of the production process. An analytical viewing of networks is made for a sort of MIS, ERP and a critical analysis of the direct application of the theory from the reference architectures. Three pillars support and characterize the first method of research. The first one is the literature review. The second one is the case study, that offers confers empirical character to the research.The third one is the methodology of organizational modeling that supplies the constructive lines of direction of the reference architecture, EKD. The contribution of the research is that the reference architecture propitiates to the company who implants the MIS, the creation of a mechanism of protection to be integrated in the organizational process. Moreover, the reference architecture promotes the systematization of the coordination resources for the implementation of the integrated solution and it provides a higher certainty and probability of being successful
Avaliação de políticas industriais de formação de polos e zonas francas sob o paradigma de cadeias de suprimento
No full textCompanies have faced a complex and highly competitive environment, with increasingly demanding consumer, cycles of smaller products, and intense technological evolution. Competition no longer occurs between isolated organizations, but it does between supply chains. Integrated management of the supply chains becomes the difference of the new form of competition. In this context, Supply Chain Management (SCM) consists in the management of existing relationships among companies trough links of different processes along the chain that produces value in the form of products and services to the customers. The main goal of this thesis was to clarify the relationship with local suppliers, as well as qualify the barriers to attract strategic suppliers to Industrial Poles/Zones far from the consumer centers and suppliers of inputs. Thus, this research assessed the regional development model of Industrial Poles/Free Zones under the paradigm of supply chains. So, the option in this study was using quantitative and qualitative research, through a multiple case study, taking as unit of analysis the relationships of five focus companies of different nationalities, such as: America, Brazilian, Chinese, Korean and Japanese. It was possible to develop this sense of thought because of the local first tier suppliers of electronics subsector of electronics subsector of the Industrial Pole of Manaus (IPM). Data were collected through managers of supply of five surveyed focal companies, as well as through a survey with the managers of supplies from local suppliers. In data analysis assumptions of Network Theory, exploratory factor analysis to reduce the number of variables, descriptive statistical techniques content analysis was used. The local supply chain shows low density into the relationships and concentrates few strategic suppliers for the global electronics industry. Local suppliers provide input with low added value, which implies that can be replaced at any time. Therefore, the local supply chains is not integrated, and there is no collaboration/cooperation in the relationships studied. The redirection to the basic Productive Process for logical development of the supply chain, economies of scale bureaucracy, lack of skilled labor, low density of Research & Development, and poor logistics infrastructure were identified as barriers that hamper the attraction of strategic suppliers to local supply chain.As empresas enfrentam hoje um ambiente complexo e altamente competitivo, com consumidores casa vez mais exigentes, ciclos de produtos cada vez menores, e com intensa evolução tecnológica. A competição não ocorre mais entre organizações que atuam de forma isolada com outras organizações igualmente isoladas, mas sim entre cadeias de suprimentos. A gestão integrada da cadeia de suprimentos torna-se o meio de diferenciação desta nova forma de competição. Nesse contexto, a Gestão da Cadeia de Suprimentos (Supply Chain Management SCM) consiste na gestão dos relacionamentos existentes entre as empresas que se relacionam por meio de ligações entre os diferentes processos existentes ao longo da cadeia, que produzem valor na forma de produtos e serviços para os clientes. O objetivo geral desta tese foi explicitar os relacionamentos com fornecedores locais, bem como qualificar as barreiras para a atração de fornecedores estratégicos para Polos Industriais/Zonas Francas distantes dos grandes centros consumidores e fornecedores de insumos. Assim, esta pesquisa avaliou o modelo de desenvolvimento regional de formação de Polos Industriais/Zonas Francas sob o paradigma de cadeias de suprimentos. Para tanto, optou-se por utilizar uma estratégia de pesquisa quantitativo-qualitativa, através de um estudo de múltiplos casos, tornando-se como unidade de análise os relacionamentos de cinco empresas focais de nacionalidade Americana, Brasileira, Chinesa, Coreana e Japonesa com os seus fornecedores locais de primeira camada do subsetor eletroeletrônico do Polo Industrial de Manaus (PIM). Os dados foram coletados por meio de entrevistas com os gestores de suprimentos das cinco empresas focais pesquisadas, e com a aplicação de uma survey junto aos gestores de suprimentos dos fornecedores locais. Na análise dos dados, foram utilizados os pressupostos da Teoria das Redes, análise fatorial exploratória para reduzir o número de variáveis, técnicas de estatística descritiva, e análise de conteúdo. A cadeia de suprimentos local apresenta baixa densidade nos relacionamentos e concentra poucos fornecedores estratégicos do setor eletrônico global. Os fornecedores locais fornecem insumos de baixo valor agregado, implicando que possam ser substituídos a qualquer momento. A cadeia de suprimentos local não é integrada e não há colaboração/cooperação nos relacionamentos pesquisados. O redirecionamento do Processo Produtivo Básico para a lógica de desenvolvimentos da cadeia de suprimentos, as economias de escala, a burocracia, a falta de mão-de-obra qualificada, a baixa densidade de pesquisa e desenvolvimento e a infraestrutura logística deficiente foram as barreiras identificadas que dificultam a atração de fornecedores estratégicos para a cadeia de suprimentos local
