Navigating together through seas of uncertainties: an extended inter-organizational view of supply chains
No full textSupply chains from different industries have expanded their activities worldwide in the last decades, seeking low-cost sourcing and supplying products to new markets. As their operations enlarged distinct continents and countries, additional and growing threats emerged from those environments affecting supply chain performance. In other words, the same process that led supply chains to global expansion also raised uncertainties, risks, and disruptions for companies. However, the external environment could not see only as a source of threats. Government institutions, cross-sector partners, competitors, and society possess resources that could be employed in inter-organizational responses beyond supply chain boundaries. This dissertation focuses on understanding how companies respond to external threats and, simultaneously, enhance other agents in the environment in collaborative efforts. Therefore, I question: How do companies and their supply chains interact with the environment under uncertainty? This dissertation investigates the influence of the external environment as a source of threats and, simultaneously, support for supply chains under uncertainty. I approached this dynamic through three essays focusing on understanding the dynamic between supply chains and the external environment under institutional uncertainties, cargo theft risks, and disruptions from the Coronavirus [COVID-19] pandemic, respectively. Those essays reveal that companies developed mechanisms to respond to threats, enhance inter-organizational support in collaborative responses, and improve their knowledge to operate under uncertainty. I contribute to the Operations and Supply Chain Management literature by exploring the dynamic between supply chains and their environment from different theoretical lenses and levels of threats.As cadeias de suprimentos de diferentes setores expandiram sua atuação em todo o mundo nas últimas décadas, buscando fontes de baixo custo e fornecendo produtos para novos mercados. À medida que suas operações incluíram novos continentes e países, novas e crescentes ameaças emergiram desses ambientes afetando o desempenho das cadeias. Em outras palavras, o mesmo processo que levou as cadeias de suprimentos à expansão global também aumentou as incertezas, os riscos e as rupturas para as empresas. No entanto, o ambiente externo não pode ser encarado apenas como uma fonte de ameaças. Instituições governamentais, parceiros de demais setores, concorrentes e sociedade possuem recursos além dos limites das cadeias de suprimentos que podem ser empregados em respostas conjuntas para ameaças em comum. Esta tese se concentra em compreender como as empresas respondem às ameaças externas e, simultaneamente, criam relações com outros agentes do ambiente em esforços colaborativos. Portanto, eu questiono: Como as empresas e suas cadeias de suprimentos interagem com o meio ambiente sob a incerteza? O objetivo desta tese é investigar a influência do ambiente externo como fonte de ameaças e, simultaneamente, suporte para cadeias de suprimentos sob incerteza. Abordei essa dinâmica por meio de três ensaios focados na compreensão da dinâmica entre as cadeias de suprimentos e o ambiente externo sob incertezas institucionais, risco de roubo de carga e rupturas da pandemia de Coronavírus [COVID-19], respectivamente. Esses ensaios revelam que as empresas desenvolveram mecanismos para responder às ameaças, construindo suporte interorganizacional em respostas colaborativas e aprimorando seus conhecimentos em operar sob incertezas. Eu contribuo para a literatura de Operações e Gerenciamento da Cadeia de Suprimentos, explorando a dinâmica entre as cadeias de suprimentos e seu ambiente de diferentes lentes teóricos e níveis de ameaças
ALTERAÇÕES NOS HÁBITOS DE COMPRA E DISTRIBUIÇÃO VAREJISTA
Get PDFO crescimento das aglomerações urbanas tem causado restrições à mobilidade de pessoas e cargas, levando os consumidores a reduzirem a propensão a deslocamentos para compras. Sendo assim, o objetivo deste estudo foi a busca de evidência de quais ramos de atividade do varejo podem ser apontados como mais sensíveis a este comportamento de compra por conveniência, bem como discutir os impactos da redistribuição espacial desta parte do varejo para a logística de distribuição nas cidades. Para isso, foram utilizados dados secundários das escolhas de locais de compra da base de dados da Pesquisa dos Orçamentos Familiares (POF) do IBGE. Foram evidenciadas mudanças dos hábitos de compra mais contundentes para alimentos e produtos de higiene pessoal, cosméticos e perfumaria. Quanto mais se compra nos bairros, mais entregas são necessárias, portanto, mais veículos de carga circulando, menos mobilidade das pessoas, e, por conseguinte, menor propensão a deslocarem-se
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
