As Narrativas Biográficas e as metodologias de investigação-acção sobre a memória e o esquecimento

The integration of Biographical Knowledge in research processes is a methodological proposal of critical empiricism that shifts the centre of production of knowledge to the research objects. We try to show haw Biographical Narratives can allow bypassing the locks and the deviations from real observation by the researcher and focus is work on actors in process. In the critique of the Eurocentric paradigm and is production of hegemonic scientific discourses by Bonaventura Sousa Santos (Santos, 2000) proposes the "south epistemologies" as a research process and the inclusion of knowledge of actors as the research field. In the article we will try to look at the process of production of biographical narratives using the tools of south epistemological proposal. We start reviewing the methodologies working on biographical objects. Then we present the preliminary studies and research we have been doing in communities in southern Mozambique in Djabula Community Centre. These results should be completed with other works on the ground, and now we opened as a collaborative process discussion on African Studies community. The project will be completed in the coming months, through the proposal of a "House of memories" to develop with the local population through articles, stories, sounds and dances that are chosen and will support the chosen narratives by the community. The projects created with local players, from their problems allow rapprochement and dialogue between the different knowledge.

Environmental impact of geometric earthwork construction in pre-Columbian Amazonia

There is considerable controversy over whether pre-Columbian (pre-A.D. 1492) Amazonia was largely “pristine” and sparsely populated by slash-and-burn agriculturists, or instead a densely populated, domesticated landscape, heavily altered by extensive deforestation and anthropogenic burning. The discovery of hundreds of large geometric earthworks beneath intact rainforest across southern Amazonia challenges its status as a pristine landscape, and has been assumed to indicate extensive pre-Columbian deforestation by large populations. We tested these assumptions using coupled local- and regional-scale paleoecological records to reconstruct land use on an earthwork site in northeast Bolivia within the context of regional, climate-driven biome changes. This approach revealed evidence for an alternative scenario of Amazonian land use, which did not necessitate labor-intensive rainforest clearance for earthwork construction. Instead, we show that the inhabitants exploited a naturally open savanna landscape that they maintained around their settlement despite the climatically driven rainforest expansion that began ∼2,000 y ago across the region. Earthwork construction and agriculture on terra firme landscapes currently occupied by the seasonal rainforests of southern Amazonia may therefore not have necessitated large-scale deforestation using stone tools. This finding implies far less labor—and potentially lower population density—than previously supposed. Our findings demonstrate that current debates over the magnitude and nature of pre-Columbian Amazonian land use, and its impact on global biogeochemical cycling, are potentially flawed because they do not consider this land use in the context of climate-driven forest–savanna biome shifts through the mid-to-late Holocene.

Intuitions in the Face of Diversity

In recent decades, intuitions' role in philosophy has been hotly debated. Many claim intuitions play an important role. Others, some armed with data, challenge the use of intuitions. This thesis reflects on this debate and advances the debate in two main ways. Having a clear understanding of the challenge which intuition-use in philosophy faces is important. Part I focuses on this. Chapters 1-2 introduce the topic of intuitions, motivate the methodological study of intuitions, and present the historical background to recent empirical challenges to intuition-use. Chapters 3-5 concern the contemporary challenge. I present the empirical evidence the challenge uses, present what I argue to be the strongest version of the challenge, and defend that challenge against some objections. How one characterises intuitions is incredibly important in philosophical methodology. If we are to properly evaluate philosophical methods vis-a-vis their use of something called intuitions { if we are to assess the empirical challenge { it is important to be clear exactly what we mean by `intuitions'. Part II focuses on this. Chapter 6 argues there is little consensus among philosophers as to what intuitions are and their role in philosophy. Chapter 7 questions whether philosophers have developed an idiolect in which `intuition' has distinctive meaning | as frequently supposed. Chapter 8 points out a common misunderstanding about intuitions in philosophy; using quantitative tools to challenge the idea that an increased use of `intuition' in philosophy is the result of an increased use of intuition. So, the developing picture is one of confusion, without a clear idea of what sense of `intuition' is important. Fortunately, Chapter 9 sets us back on the right track. It sets out a positive programme for evaluative methodology: methodologists should adopt a permissive conception of intuitions and make fine distinctions between different intuitions, so long as we can track those distinctions while philosophising.

Testverktyg för test av mobila applikationer : En jämförande fallstudie

Användandet av mobila applikationer har växt radikalt de senaste åren och de samverkar med många system. Därför ställs det högre krav på kvaliteten och att applikationen ska anpassas till många olika enheter, operativsystem samt plattformar. Detta gör att test av mobila applikationer blivit viktigare och större. Detta arbete har bedrivits som en jämförande fallstudie inom området test av mobila applikationer samt testverktyg. Syftet har varit att beskriva hur testning av mobila applikationer sker idag vilket gjorts genom litteraturstudier och intervjuer med IT-företag. Ett annat syfte har varit att utvärdera fyra testverktyg, deras för- och nackdelar samt hur de kan användas vid testning av mobila applikationer och jämföras mot manuell testning utan testverktyg. Detta har gjorts genom att skapa förstahandserfarenheter baserat på användandet av testverktygen. Under arbetet har vi utgått från mobila applikationer som vi fått tillgång till av Triona, som varit vår samarbetspartner.Idag finns många olika testverktyg som kan användas som stöd för testningen men få företag har implementerat något eftersom det kräver både tid och kompetens samt valet av testverktyg kan vara svårt. Testverktygen har olika för- och nackdelar vilket gör att de passar olika bra beroende på typ av projekt och applikation. Fördelar med att använda testverktyg är möjligheten att kunna automatisera, testa på flera enheter samtidigt samt få tillgång till enheter via molnet. Utmaningarna är att det kan vara svårt att installera och lära sig testverktyget samt att licenserna kan vara dyra. Det är därför viktigt att redan innan implementationen veta vilka tester och applikationer testverktygen ska användas till samt vem som ska använda det. Utifrån vår studie kan slutsatsen dras att inget testverktyg är helt komplett men de kan bidra med olika funktioner vilket effektiviserar delar av testningen av mobila applikationer.

Prospects for Developing Countries

While developing countries generally shared the sentiment that they were going to suffer from the effects of climate change policy, evidence to the contrary has emerged during the short time since the Kyoto Protocol’s entry into force. Defying expectations that developing nations could only lose from climate change policy, Brazil has shown that it is actually quite possible to benefit significantly from these policies. Brazil has been proactive in developing the infrastructure to become involved in climate change negotiations, as well as using policy tools such as the CDM. Its actions have resulted in significant economic, developmental, and environmental benefits. The case of Brazil allows for some insight into how other countries with similar developmental profiles —specifically China and India—stand to benefit from climate change policy, and how these benefits will translate into policy for future climate negotiations.

Adaptações do sistema de informações gerenciais para atender necessidades de empresas envolvidas com a implantação do pensamento enxuto: um estudo de caso

The management system based on lean thinking has led to significant changes in the companies that have decided to adopt it. Frequently, those changes do not create a sustainable position coherent with the good results that are obtained. Many are the causes being discussed and analyzed, not only in academia, but also by lean manufacturing institutes and companies. The existing practices related to the managerial information system and the implementation, development, and maintenance of the lean journey may be some of such causes. This dissertation emphasizes whether the changes generated by this type of management are being followed by the managerial information system. The development of such system was in many cases based on mass production, whose principles go against lean manufacturing concepts. Thus, the objective of this dissertation is to verify whether the traditional managerial information system can meet the needs of the companies that adopt lean manufacturing principles. Through a case study based on qualitative and exploratory research in an electronic equipment assembling company, the stage of the implementation of lean thinking concepts at the time of the field research was analyzed, as well as whether the metrics, financial and non financial indicators were suitable for lean principles. The aim of such study was to empirically verify if the criticism found in the existing literature was pertinent or not. The data collected through the analysis of the documentation, the interviews with managers and in loco observation was treated through the content analysis method. The main conclusion of the research is that, although the company in question is investing in training and applying lean principles in its production line and in some administrative activities, the current managerial information system does not demonstrate the specific results obtained with lean principles. However, how changes to the managerial information system will be implemented is yet to be determined. Currently, metrics and indicators aligned with lean management are being added to the managerial reports. As more lean tools are employed, mainly with the consolidation of more value streams, the company has already diagnosed the need for new indicators. The main office has started a diagnosis of measurement and control systems in a product line in one of its affiliates with the goal of studying the possibility of applying the so called lean accounting in the future.

Structural analysis of the place of wine in Brazil

With the constant decrease of the wine consumption in traditional winemaking countries, more and more Brazil is seen as an appealing market. But the country also pretends to become an international player of winemaking in its own right. Both the participants of the Brazilian wine industry and the foreigners trying to get advantage of this promising market are facing new challenges to develop the consumption of wine in the world’s fifth largest country. Among all the possible actions to be taken in that sense, it also is worth taking time for a collective thought on the place of wine in the country, as well as the factors that shape it. What are these factors, which ones really make the difference, and what is their respective impact on the evolution of the place of wine in the country? After drawing the big picture of the wine market situation, this thesis tries to identify the levers of the evolution of the place of wine in Brazil. Using the tools of prospective, it aims at putting into perspective the different driving forces that influence its development, and in particular the relative influence of the political drivers. This paper also intends to be a first step of a prospective study as it constitutes a solid base for scenario planning. This paper is divided in five chapters starting with “introduction”, followed by chapter 2 “Theoretical framework”. Chapter 3 is “Methodology”, followed by chapter 4 “Description and analysis of the results”. Finally the results are discussed and concluded in the last part “Conclusions and implications for future studies”.

Sincretização do controle de constitucionalidade no ordenamento jurídico brasileiro: abstratização do controle difuso e concretização do controle abstrato

Considerando-se as recentes decisões do Supremo Tribunal Federal no controle de constitucionalidade, percebe-se o movimento de sincretização entre os controles abstrato e concreto. A visão da atual jurisdição constitucional revela que as últimas criações legislativas foram inseridas no controle abstrato, sendo o caminho utilizado para resolução das principais controvérsias judiciais, com seus efeitos erga omnes e vinculantes. Esse panorama não afastou a utilização do controle concreto, que se renova ao se aproveitar dos instrumentos do controle concentrado abstrato. Não apenas o controle concreto e difuso está se beneficiando do controle abstrato, como também a recíproca é verdadeira. O controle abstrato também se beneficia ao valer-se de diversos instrumentos que não seriam possíveis por suas características abstratas. O objetivo do presente trabalho é analisar esse movimento, através de casos emblemáticos e instrumentos criados pelas Leis que tratam sobre o controle de constitucionalidade, a fim de comprovar esse novo cenário na ordem jurídica brasileira. Este trabalho foi realizado através de pesquisas bibliográficas e casos perante o Supremo Tribunal Federal. O resultado da análise comprova essa tendência na utilização de pressupostos que seriam apenas de um controle, sendo utilizado pelo outro. Isso representa um grande avanço para o tema controle de constitucionalidade que tende cada vez mais a ser sincretizado.

Controles sobre o Judiciário geram governança e eficiência? Estudo sobre o CNJ e a Justiça Estadual

O objetivo desta tese é investigar a atuação do órgão de controle judicial no Poder Judiciário, focando na dimensão “Desempenho Administrativo Judicial”. Esta tese visa complementar o modelo de Taylor (2008) adicionando o CNJ como um elemento da melhoria do desempenho dos tribunais, por meio da implantação de ferramentas gerenciais e ocasionando impactos políticos e institucionais. O estudo se apoia no contexto político e organizacional do Judiciário para apresentar um complemento ao entendimento vigente sobre os mecanismos de mensuração de desempenho. Os impactos do CNJ foram analisados a partir de sete aspectos do processo de Reforma do Judiciário: 1. Padronização das estruturas; 2. Sistemas de gerenciamento centralizados; 3. Padronização de procedimentos internos; 4. Centralização orçamentária; 5. Financiamento de unidades judiciais; 6. Procedimentos disciplinar contra irregularidades e más condutas de magistrados; 7. Critérios meritocráticos e promoção de magistrados. Os dados foram coletados por meio de entrevistas estruturadas com ex-conselheiros e conselheiros atuais do CNJ e considerou os dez anos de existência do CNJ (2004-2013), fornecendo uma perspectiva longitudinal. A análise temática ou categorial foi escolhida como a principal da técnica de análise de conteúdo. Os dados foram segmentados por questões, por categorias prévias e por categorias estabelecidas posteriormente. Foi evidenciado que o CNJ apresenta um efeito direto de atuação no “Desempenho Administrativo Judicial”: i) usando ferramentas de gestão que permitem os tribunais aprimorar a organização interna e elevar o nível de maturidade de governança; ii) moralizando e fiscalizando os Tribunais por meio de inspeções frequentes realizadas pela Corregedoria Nacional de Justiça que objetiva a resolução das irregularidades e o afastamento dos magistrados com más condutas no exercício do cargo. As evidências identificaram também impactos indiretos: i) o CNJ como um coordenador de ações do Judiciário, articulando melhor as relações com os representantes do Executivo e do Legislativo na obtenção de mais recursos orçamentários e financeiros para os tribunais; ii) o CNJ aumenta a autonomia do Judiciário reconhecendo os esforços de gestão dos tribunais e compartilhando as melhores práticas com os outros tribunais, com impactos na melhoria de infraestrutura e no desempenho. O aumento de controle promovido pelo CNJ reforçou a governança e a eficiência dos tribunais, mas com perca de autonomia num primeiro momento. Por outro lado, num segundo momento, possibilitou uma mudança de perfil nas indicações de seus conselheiros numa tentativa de enfraquecer o controle e aumentar autonomia dos tribunais.

Fundo de investimento imobiliário: metodologia para subsidiar o investidor a formar uma carteira eficiente

O presente trabalho tem por objetivo subsidiar o investidor de Fundos de Investimento Imobiliário na escolha de uma carteira de aplicação de FIIs, visando obter performance igual ou superior ao índice de referência do setor (IFIX). Tal subsídio é constituído, inicialmente, por uma metodologia que considera que o conceito de Carteira Eficiente (Risco/Retorno) preconizada por Markowitz pode trabalhar em conjunto com a dimensão do conceito das Finanças Comportamentais, liderada por Daniel Kahneman, constituindo as bases de orientação do investidor. Acrescentamos o caminho metodológico com as indicações, sugeridas por Bazerman e Moore, no processo de tomada de decisão, que reduza os efeitos de heurísticas e vieses.

Inexpensive solution for real-time video and image stitching

Image stitching is the process of joining several images to obtain a bigger view of a scene. It is used, for example, in tourism to transmit to the viewer the sensation of being in another place. I am presenting an inexpensive solution for automatic real time video and image stitching with two web cameras as the video/image sources. The proposed solution relies on the usage of several markers in the scene as reference points for the stitching algorithm. The implemented algorithm is divided in four main steps, the marker detection, camera pose determination (in reference to the markers), video/image size and 3d transformation, and image translation. Wii remote controllers are used to support several steps in the process. The built‐in IR camera provides clean marker detection, which facilitates the camera pose determination. The only restriction in the algorithm is that markers have to be in the field of view when capturing the scene. Several tests where made to evaluate the final algorithm. The algorithm is able to perform video stitching with a frame rate between 8 and 13 fps. The joining of the two videos/images is good with minor misalignments in objects at the same depth of the marker,misalignments in the background and foreground are bigger. The capture process is simple enough so anyone can perform a stitching with a very short explanation. Although real‐time video stitching can be achieved by this affordable approach, there are few shortcomings in current version. For example, contrast inconsistency along the stitching line could be reduced by applying a color correction algorithm to every source videos. In addition, the misalignments in stitched images due to camera lens distortion could be eased by optical correction algorithm. The work was developed in Apple’s Quartz Composer, a visual programming environment. A library of extended functions was developed using Xcode tools also from Apple.

Combating shoulder-surfing: a hidden button gesture based scheme

This project describes an authentication technique that is shoulder-surfing resistant. Shoulder surfing is an attack in which an attacker can get access to private information by observing the user’s interaction with a terminal, or by using recording tools to record the user interaction and study the obtained data, with the objective of obtaining unauthorized access to a target user’s personal information. The technique described here relies on gestural analysis coupled with a secondary channel of authentication that uses button pressing. The thesis presents and evaluates multiple alternative algorithms for gesture analysis, and furthermore assesses the effectiveness of the technique.
