    This dissertation aims to provide an independent view of the future of FedEx Corporation. Despite the recent sell-off after ground margins fell short of investors' expectations, FedEx is benefiting from interesting trends across all the business segments. Those trends include the shift towards online shopping accelerated by the pandemic, a recovery in the economy around the world and the constraint of passenger capacity. Therefore, this report points towards a buy recommendation with a target price of $286.50 as of December 31st, 2021, translating into an11.4% total shareholder return over the next 12-months

    Exploring social influence in crowdsourcing

    This study addresses the phenomenon of social influence in crowdsourcing platforms and, inparticular, it sought to explore whether depending on personal, contextual or cultural, characteristics, individuals which participate in such endeavors are more or less prone to become influenced by a majority when performing an objective task. In crowdsourcing platforms individuals participate through different decision making mechanisms such as voting, averaging and consensus. The exposure to informational cues regarding the aggregate output of a crowd is hypothesized to constitute a pressure upon the individuals' behavior. Our findings provide evidence about the existence of and proneness to socialinfluence in crowdsourcing platforms. These research also showsthat skill level and homophilousties among participants are a stronghold against the pressures of the majorities. These results empirically demonstrate that in the presence of an informational cues a large amount of individuals accept majorities' outcomes as an evidence of the reality. Through the current findings, we provide insighton the phenomenon of social influence in crowdsourcing platforms and, by unveiling these results, give a contribution towards managing such platforms

    Assessing the influence of floating constructions on water quality and ecology

    Get PDF
    Large floating projects have the potential to overcome the challenge of land scarcity in urban areas and offer opportunities for energy and food production, or even for creating sustainable living environments. However, they influence the physical, chemical, biological and ecological characteristics of water bodies. The interaction of the floating platforms affect multiple complex aquatic processes, and the potential (negative/positive) effects are not yet fully understood. Managing entities currently struggle with lack of data and knowledge that can support adequate legislation to regulate future projects. In the Netherlands the development of small scale floating projects is already present for some years (e.g. floating houses, restaurants, houseboats), and more recently several large scale floating photovoltaic plants (FPV) have been realized. Several floating constructions in the Netherlands were considered as case-studies for a data-collection campaign. To obtain data and images from underneath floating buildings, underwater drones were equipped with cameras and sensors. The drones were used in multiple locations to scan for differences in concentrations of basic water quality parameters (e.g. dissolved oxygen, electrical conductivity, algae, light intensity) from underneath/near the floating structures, which were then compared with data from locations far from the influence of the buildings. Continuous data was also collected over several days using multi-parameter water quality sensors permanently installed under floating structures

    Distributed production planning and control agent based system

    A model of an Agent based Production Planning and Control (PPC) system able to be dynamically adaptable to local and distributed utilization of production resources and materials is presented. The PPC system is based on the selection of resources to deal with one order of different quantities of one product each time. In this way it is build one scheduling solution for that particular order. The production resources are selected and scheduled using a multiagent system supported by an implementation of the Smith Contract Net, using Java Spaces technology. The multiagent system is based on three main agents: Client, Resource and Manager. These agents negotiate the final product, and the correspondent components, requested by the client. An order for each product (component) triggers a process of dynamic design of a production system to fulfill that particular order. This system exists till the end of the order

    O presente estudo inscreve-se no âmbito dos Estudos da Criança e elege a sua área específica nas questões linguísticas, assumindo os pressupostos teóricos e metodológicos da Análise do Discurso, considerando igualmente o influxo de áreas conexas. Analisa textos de manuais escolares (livros didáticos) e pretende tornar visíveis as imagens que tais textos constroem das crianças e da infância, assim como os recursos linguísticos mais relevantes associados a tal construção.Conclui que as crianças retratadas nos textos são seres sem voz e sem poder, consumidoras mas não coprodutoras de cultura, e que os textos inculcam valores conformadores, de manutenção da ordem social estabelecida. Apresenta sumariamente o conjunto das estratégias linguísticas mais relevantes para que os textos atinjam os objetivos ilocutórios propostos.This study falls within the scope of Child Studies and defines its specific area in language studies. It assumes the theoretical and methodological fundamentals of discourse analysis, also considering the influence of related areas. It analyses texts present in textbooks and aims to reveal the images that such texts build of children and childhood, as well as the most relevant linguistic resources associated with such construction.The study concludes that children portrayed in these texts are voiceless and powerless; they are consumers but not co-producers of culture; and the texts instil conservative values aimed at maintaining the social order. It concisely shows the set of most relevant linguistic strategies that the texts use in order to reach their illocutionary goals.CIEC - Centro de Investigação em Estudos da Criança, UM (UI 317 da FCT

    ORIENTAÇÕES METODOLÓGICAS PARA UM ENSINO DE FILOSOFIA BASEADO EM VIRTUDES INTELECTUAIS

    Get PDF
    Pretendo apresentar aqui a fundamentação de uma proposta metodológica para o ensino de Filosofia, a partir de insights sobre a concepção de “virtudes”, elaborados, principalmente, pela autora contemporânea Linda Zagzebski,e marginalmente por Gilbert Ryle. Meu objetivo é sustentar que a mediação entre aluno e conhecimento não ocorre de forma mágica, ou numa relação passiva do aluno frente ao conteúdo exposto, mas envolve um contexto epistemológico relacionado a um conjunto de práticas e habilidades que estimulem as virtudes intelectuais necessárias para qualquer aprendizado. Para isso, inicialmente explico o que devemos entender por metodologia de ensino, dentro da concepção teórica desenvolvida. Em seguida, esclareço algumas noções sobre o que chamamos de “conhecimento”, e sua relação com o aprendizado. Por fim, desenvolvo a ideia chave do trabalho a partir das considerações sobre virtudes intelectuais

    Compatibilizando Teoria da Ação e Racionalidade Prática a Partir do Conceito de “Intenção”

    Get PDF
    O objetivo desse artigo será apresentar parte do debate atual sobre o papel da intenção na teoria da ação e na racionalidade prática. Para isso, iniciarei com a perspectiva do autor responsável pela retomada da filosofia da ação na contemporaneidade, Donald Davidson. Após oferecer uma breve exposição da concepção davidsoniana da intenção e da ação, e sobre os modelos teóricos “crença-desejo” e “crença-desejo-intenção” na filosofia da ação, pretendo desenvolver algumas considerações sobre o aspecto normativo da racionalidade prática (no sentido em que envolve “razões para”) e o papel que a intenção tem nesse processo. Para isso, apresento o modo como Michael Bratman (1987) desenvolve uma linha de argumentação a favor de um tipo de função que a intenção pode desempenhar como input no raciocínio prático, argumentando em prol de um papel genuíno para a intenção em uma concepção de racionalidade prática. Por fim, apresento alguns desdobramentos da discussão sobre o modelo crença-desejo versus o modelo crença-desejo-intenção como propostas conflitantes para a explicação da racionalidade prática.AbstractThis paper aims to present part of the current debate about the role of intention in action theory and practical rationality. For this, I begin with the perspective of the philosopher responsible for the resumption of contemporary philosophy of action, Donald Davidson. After a brief exposition of davidsonian conception of intention and action, and of “belief-desire” and “belief-desire-intention” theoretical models in philosophy of action, I intend to develop some considerations about the normative aspect of practical rationality (in the sense that it involves “reasons for”) and the role of intention in that process. For this, I present the way that Michael Bratman (1987) develops a line of argumentation in favor of a certain type of role intention can play as input in practical reasoning, arguing for a genuine role for intention in a conception of practical rationality. Finally, I present some outspread on belief-desire versus belief-desire-intention discussion, as competing proposals for practical rationality explanation
