    Dissertação de mestrado em Gestão, apresentada à Faculdade de Economia da Universidade de Coimbra, sob a orientação de Paulo Miguel Marques Gama Gonçalves.Este estudo pretende aprofundar os conhecimentos ainda escassamente estudados sobre a relação entre o nível de optimismo dos gestores de topo e as suas implicações sobre o exercício de gestão e a estratégia da empresa. Consequentemente procurará também dar um contributo para o conhecimento do perfil optimístico de gestores de topo portugueses e da sua relação com o exercício de gestão. Para tal foi utilizado um questionário já anteriormente aferido para a população portuguesa, que mede o optimismo disposicional do sujeito, e os resultados deste questionário foram cruzados com diversas variáveis económico-financeiras das empresas estudadas.Os resultados foram inconclusivos, não se tendo encontrado relações estatísticas significativas entre as variáveis em estudo

    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

    Serviço de reconfiguração de dispositivos IoT

    This work presents an optimization model for sending telemetry from IoT devices, using the Twin Device tool present in Microsoft’s cloud server services platform, called Azure. The optimization is done through a server, developed in Python, which interprets the telemetry received, defines the current state of the device and updates the settings of the device and emits it through Twin Device. The result in normal operating states was a drastic decrease in the number of packets and consequently a smaller volume of data trafficked on the network, already in a critical state, the amount of packets increased and consequently a considerably greater volume trafficked through the network.Esse trabalho apresenta um modelo para aprimorar o envio de telemetria de dispositivos IoT (Internet of Things), utilizando a ferramenta de Dispositivo Gêmeo presente na plataforma de serviços de servidores em nuvem da Microsoft, chamada Azure. O aprimoramento é feito através de um servidor, desenvolvido em Python, que interpreta a telemetria recebida, define o estado atual do dispositivo e atualiza as configurações do dispositivo emissor por meio do Dispositivo Gêmeo. O resultado para o dispositivo em seus parâmetros normais de operação foi uma redução de 91% na quantidade de pacotes, consequentemente no volume de dados trafegados na rede. Já fora de seus parâmetros normais, a quantidade de pacotes aumentou 145% e consequentemente o volume de dados trafegados pela rede também

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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
