Abstract:
Os municípios são organismos da Administração Pública, vocacionados para a gestão autárquica, com responsabilidades sociais e culturais, bem como especificidades e características próprias, que são reveladas através da sua imagem institucional. Partindo do estudo diacrónico do signo como elemento identificador e diferenciador, e no sentido de entender a importância passada e presente da identidade visual dos municípios portugueses, efectua-se uma investigação acerca da evolução dos símbolos concelhios, dos brasões que lhes estão associados e das marcas que, na contemporaneidade, lhes acrescentam outras particularidades identitárias. Procura-se, por um lado, destrinçar a correlação existente entre o brasão e a marca como símbolos identitários, a sua utilização conjunta ou a sua clara separação, a normalização dos elementos utilizados ou a ruptura com os laços históricos. Por outro lado, evidenciar a identidade preconizada pelos órgãos de gestão, bem como os valores e a singularidade que pretendem veicular e que encerram nos seus símbolos gráficos. O objectivo fundamental é o estudo e a análise desses signos, procurando estabelecer-se uma concepção global, a par de evidenciar a estratégia de comunicação, partindo do conhecimento e compreensão da evolução dos símbolos distintivos ao longo da história, caracterizando-os mediante três prismas: como marcas de identificação, como marcas de diferenciação e como sistemas de comunicação.
City councils are public administration organisms, oriented to autarchic management, with social and cultural responsibility, as well as specific characteristics, which are revealed by their institutional image. Starting with the diacronic study of the sign as an identifier and differential element, and looking for the meaning of the past and present importance of the visual identity of portuguese cities, this investigation is about the evolution of county symbols, their associated arms and the brands that nowadays will grant them other unique particularities. Part of this search was pointed to distinguish the existent co-relation between the coat of arms and the brands as identity symbol-marks, its use as one or its obvious separation, the standard application of the elements or the factual rupture with historical bonds. The other side of this question is putting out the management bodies recognized identity, as well as the values and the singularity they intend to acknowledge, which are contained in their graphic symbols. The main purpose is the study and analysis of those symbols, looking to establish a global conception, putting light to the communication strategy, starting from the knowledge and understanding of the striking symbols throughout history, distinguishing them according to three identifier views: as identification signs, as differential brands and as communication systems.

Esta tese faz uma revisão história do termo “documental” enquanto gênero fotográfico a fim de colocar em perspectiva os diferentes sentidos que ele adquire ao longo do século XX. Como tal termo origina-se da palavra documento, analisamos primeiramente o duplo significado original e moderno de ensino e prova a ela atribuído, bem como as nuances na associação entre estes diferentes significados e a fotografia. Se este medium, em seus primórdios, foi predominantemente usado no campo da ciência e da investigação como um tipo de documento visual de caráter testemunhal e probatório, o posterior reconhecimento da sua linguagem e das suas qualidades formais o aproximaram do campo da arte, o que implicou novos entendimentos sobre os seus valores documentais e estéticos. Assim, as transformações por que passou a chamada “fotografia documental” e as suas repercussões no Brasil na segunda metade do século XX foram analisadas nesta pesquisa a partir das obras de Claudia Andujar, Miguel Rio Branco e Mario Cravo Neto com o propósito de avaliar o papel destes três fotógrafos no processo tanto de questionamento deste gênero quanto de renovação das práticas de documentação desenvolvidas no país. Para dimensionar a importância de suas participações em tal processo, foram selecionados dois livros de cada autor: Yanomami (1980) e duas séries de A vulnerabilidade do ser (2005) de Andujar, Dulce Sudor Amargo (1985) e Silent Book (1998) de Rio Branco e, por fim, Bahia (1980) e Laróyè (2000) de Cravo Neto. A análise destas publicações mostrou que os seus autores, ao ampliarem as possibilidades de produção e, sobretudo, de uso do documento fotográfico a partir de estratégias técnicas, estéticas e conceituais que mais se aproximam daquelas adotadas em projetos de caráter artístico, romperam não com a documentação em si, mas com os seus modelos tradicionais baseados tanto na ideia de fotografia como reprodução da realidade como no conceito de “fotografia documental” que, a despeito da pluralidade de seus sentidos, foi, em princípio, fortemente associada à imprensa ilustrada e à prática da reportagem social – o que marcou, portanto, um período singular na história da fotografia brasileira.
This thesis makes a historic review of the term “documentary” as a photographic genre, in order to put in perspective the different meanings it acquired throughout the 20th century. Since the term derives from the word document, we first analyze the original and modern double meaning of teaching and testing assigned to it, as well as nuances in the association of these different meanings and photography. If this medium, in its early days, was mainly used in the scientific and investigatory field as a type of visual document of testimonial and probative character, the posterior recognition/acceptance of its language and formal qualities brought it closer to the artistic field, which implied in new understandings about its documentary and aesthetic values. Thus, the changes which "documentary photography" went through and its repercussions in Brazil in the second half of the 20th century were analyzed in this research. The works by Claudia Andujar, Miguel Rio Branco and Mario Cravo Neto were investigated in this research with the purpose of assessing the role of these three photographers in the process of both questioning this genre and contributing for the renewal of the documentary practices developed in the country. In order to evaluate the importance of their participation in such process, two books of each author were selected: Yanomami (1980) and two series of A vulnerabilidade do ser (2005) by Andujar; Dulce Sudor Amargo (1985) and Silent Book (1998) by Rio Branco; and, finally, Bahia (1980) and Laróyè (2000) by Cravo Neto. The analysis of these publications showed that when the production possibilities and the use of the photographic document – especially deriving from technical, aesthetic and conceptual strategies that are closer to the ones used in artistic projects – were increased, these photographers ruptured not with the documentation per se, but with its traditional models based in both the idea of photography as reproduction of reality and in the concept of “documentary photography”. Concept which, despite its plurality of meanings, was at first heavily associated to the illustrated press and to the practice of social report, thus, marking a unique period in the history of the Brazilian photography that is now reconfigured by different photographers and artists such as the crucial three names considered in these thesis.

Abstract:
Summary

Brain dysfunction is a frequent complication of sepsis and is usually defined as “sepsis-associated encephalopathy” (SAE). Its pathophysiology is complex and related to a number of processes and pathways, while the exact mechanisms producing neurological impairment in septic patients have not been completely elucidated. Alterations in cerebral blood flow (CBF) have been suggested as a key component for the development of SAE. Reduction of CBF may be caused by cerebral vasoconstriction, induced either by inflammation or hypocapnia. More importantly, the natural mechanisms that protect the brain from reduced/inadequate CBF can be impaired in septic patients, especially in those with shock, and this further contributes to cerebral ischemia if blood pressure drops below a critical threshold. Hypercapnia is associated with a narrower autoregulatory plateau, which may potentially results in large CBF variations when mean arterial pressure (MAP) varies within usual targets. However, few data are available on the role of PaCO2 on cerebral autoregulation (CA). Finally, as SAE occurs also in patients without hemodynamic instability, alterations in brain tissue perfusion could occur independently from hypotension; thus, alterations in cerebral microcirculation, which largely regulates regional flow and blood-cellular nutrients exchanges, could contribute to SAE. In septic animals, these microcirculatory abnormalities could be implicated in the development of electrophysiological abnormalities observed during sepsis and contribute to neurological alterations. However, these findings were limited by several factors, including the technique used to assess the microcirculation, the short time of observation and the limited amount of fluid resuscitation used in those models.

In the first part of this work, I evaluated CA and the potential influence of PaCO2 on CA in patients with septic shock. In 21 mechanically ventilated patients, I observed that 14 of them had impaired CA. All the 7 patients with a PaCO2 ≥ 40 mmHg but only 7 of the 14 patients with a PaCO2 <40 mmHg had an impaired CA (p=0.046). Specifically, 4/9 (44%) patients with PaCO2 < 35 mmHg, 7/9 (77%) with PaCO2 between 35 and 42 mmHg, and 3/3 (100%) with PaCO2 > 42 mmHg had impaired CA. The Receiver Operating Characteristic (ROC) analysis showed that a PaCO2 threshold of 38 mmHg had a sensitivity of 50% and a specificity of 100% for the prediction of impaired CA, with an area under the ROC curve of 0.76 (95% confidence interval: 0.52–0.91).

In the second part of this work, I hypothesized that altered cerebral microcirculation may occur in the early phase of sepsis and contribute to brain hypoxia. In a clinically relevant model of ovine fecal peritonitis, I showed that there was a progressive deterioration of cerebral microvascular flow in septic animals (n=10) when compared to sham animals (n=5), starting already after 6 hours from sepsis induction and becoming significant at 12 hours thereafter. Moreover, changes in the cerebral microcirculation were not related to changes in MAP, cardiac output or blood lactate levels, suggesting that these alterations in the brain may occur even when global perfusion pressure is maintained, i.e. in non-hypotensive conditions. In a second study, including 10 septic and 5 sham animals, I found that cortical microvascular alterations were associated with decreased cerebral oxygenation. Furthermore, cerebral metabolic disturbances compatible with tissue hypoxia (i.e. increased brain lactate/pyruvate ratio, LPR) occurred mostly during shock, suggesting that hypotension is a critical factor in the development of anaerobic metabolism in the septic brain. Nevertheless, I showed in a third study (n=8) that the reversal of hypotension using vasopressor agents, although increased cerebral oxygenation and slightly reduced LPR, did not significantly influence the alterations of cerebral microcirculation and was associated with an increase in glutamate and glycerol, suggesting ongoing excitotoxicity and cellular damage. These alterations in cerebral microcirculation, oxygenation and metabolism may then contribute to the pathogenesis of SAE.

Résumé

La dysfonction cérébrale est une complication fréquente du sepsis et elle est généralement identifiée comme « encéphalopathie associée au sepsis » (sepsis-associated encephalopathy, SAE). La physiopathologie de la SAE est complexe et liée à des nombreux processus et voies de signalisation, même si les mécanismes qui induisent cette dysfonction cérébrale chez les patients en sepsis n’ont pas été clairement élucidés. Des anomalies du débit sanguin cérébral (cerebral blood flow, CBF) ont été proposées comme une des déterminants pour le développement de l’SAE. La réduction du CBF pourrait être induite par une vasoconstriction cérébrale, élicitée pas l’inflammation ou par l’hypocapnie. De plus, les mécanismes qui naturellement règlent le CBF pour qu’il soit ni diminué ni inadéquat aux besoins cellulaires peuvent être altérés pendant le sepsis, particulièrement en cas de choc septique, et ceci pourrait davantage contribuer au développement de zones d’hypoperfusion cérébrale si la pression artérielle diminue au-dessous d’un seuil critique. Un autre point important est que l’hypercapnie est associée à une diminution du plateau d’autorégulation du CBF, ce qui pourrait potentiellement causer des larges variations du CBF endéans des valeurs de pression artérielle considérés comme normaux en pratique clinique; malheureusement, très peu de données sont disponibles sur le rôle de la PaCO2 sur l’autorégulation cérébrale (cerebral autoregulation, CA). Enfin, vu que l’SAE survient aussi chez des patients qui n’ont pas d’instabilité hémodynamique, des anomalies de la perfusion cérébrale régionale pourraient se produire en absence de toute hypotension artérielle ;en effet, des altérations de la microcirculation cérébrale, qui règle le débit sanguin au niveau des tissues et l’échange d’oxygène et nutriments entre la circulation sanguine et le cellules, peuvent aussi contribuer au développement de la SAE. Dans des modelés expérimentaux de sepsis, les altérations microcirculatoires ont été associées à des troubles électrophysiologies et à la présence d’anomalies « cliniques ». Cependant, ces données ont été biaisées par le type de technique utilisée pour évaluer la microcirculation, le temps d’observation très court et la quantité limitée de fluides administrés au cours de la réanimation liquidienne dans ces modelés.

Dans la première partie de ce travail, j’ai décrit les anomalies de la CA et l’impact de la PaCO2 sur la CA chez des patients en choc septique. En étudiant 21 patients en ventilation mécanique, j’ai pu observer que 14 d’entre eux avaient une CA altérée, y compris 7/14 avec une PaCO2 < 40 mmHg et 7/7 avec une PaCO2 ≥ 40 mmHg (p = 0.046). De plus, 4/9 (44%) avec PaCO2 < 35 mmHg, 7/9 (77%) avec PaCO2 between 35 and 42 mmHg, and 3/3 (100%) avec PaCO2 > 42 mmHg avaient une CA altérée. L’analyse selon la « Receiver Operating Characteristic » (ROC) montrait une sensibilité de 50% et une spécificité de 100% pour prédire une CA altérée, avec un seuil de PaCO2 de 38 mmHg (l’aire sous la courbe de l’analyse ROC était à 0.76 [95% ICs: 0.52–0.91]).

Dans la deuxième partie de ce travail, j’ai émis l’hypothèse que des anomalies de la microcirculation cérébrale peuvent survenir dans la phase précoce du sepsis et contribuer au développement d’une hypoxie tissulaire. Dans un modelé de péritonite fécale induite chez le mouton, très proche de la situation clinique, j’ai pu montrer que il existe une détérioration progressive de la microcirculation cérébrale chez les animaux septiques (n-=10) quand comparés aux animaux témoins (n=5) qui commence déjà a la sixième heure de l’induction du sepsis and devient significative après 12 heures. De plus, les changement de la microcirculation cérébrale n’étaient pas corrélés à ceux de la pression artérielle, du débit cardiaque ou des taux de lactate, ce qui suggère que ces anomalies peuvent se produire aussi en conditions de stabilité hémodynamique. Dans une deuxième étude comprenant 10 animaux septique et 5 témoins, j’ai observé que les anomalies microcirculatoires étaient associées à une diminution de l’oxygénation cérébrale tissulaire. Toutefois, les anomalies du métabolisme cérébral compatible avec une hypoxie tissulaire (des valeurs élevées du rapport lactate/pyruvate, LPR) se développaient que dans la phase du choc septique, indiquant que l’hypotension artérielle est le facteur déterminant pour ces anomalies métaboliques au cours du sepsis. Cependant, dans une troisième étude sur 8 animaux en sepsis, j’ai démontré que la correction de l’hypotension par administration de vasopresseurs, même si elle était associée à une augmentation de l’oxygénation cérébral et une diminution du LPR, n’améliorait pas de façon significative la microcirculation cérébrale et s’accompagnait par une augmentation des taux de glutamate et glycérol, ce qui plaidait plutôt pour un excitoxicité persistante et une progression des lésions cellulaires. Toutes ces anomalies de microcirculation, oxygénation et métabolisme cérébral pourraient contribuer à la pathogenèse de l’SAE.

Abstract:
Cette thèse examine la relation complexe et la causalité entre la migration et le développement, sujet d'actualité vus les flux croissants de migrants et les transferts de fonds privés. La revue de la littérature théorique et empirique montre la complexité de cette relation, et l’absence de consensus dégagé par les travaux menés sur les causes et les effets de la migration sur le développement. Sur les causes de migration, une première estimation empirique montre qu’elle fait partie intégrante du processus de développement et n’est donc pas une simple conséquence de faibles niveaux de développement: le niveau de développement des pays d'origine s’accroissant, les aspirations et les capabilités des populations augmentent et si celles-ci font face à l'absence d’opportunités, elles vont migrer à condition d’en avoir les capabilités (compétences requises, moyens financiers, politiques de migration, etc.). Concernant l’impact de la migration, une deuxième estimation empirique montre un effet positif sur le développement via les transferts privés. Les modèles indiquent que leur contribution se fait à travers deux principaux canaux, l'investissement en capital et le capital humain (éducation et santé), lesquels sont susceptibles de permettre un développement à long terme des pays d'origine. Au niveau micro, une troisième série de modèles étudie le mécanisme de cet impact au niveau de ménages, à partir du cas de l'Egypte. Ces modèles confirment l'importance des transferts privés sur les niveaux d'éducation et de santé dans les ménages qui les reçoivent. Ces résultats sont censés contribuer à la compréhension de cette relation complexe entre migration et développement
This thesis is concerned with the causal and complex relation between migration and development. A timely subject, especially with increasing flows of migrants and the remittances these migrants send home. Both the theoretical and empirical literature reviews address the complexity of this relation but consensuses on the causes and impacts of migration on development are generally inconclusive. On the causes of migration, our first empirical estimation shows that migration is part of the development process and not a simple result of its low levels: the increasing development level of the home countries increase the aspirations and capabilities of their populations and if these are faced with lack of opportunities at home, individuals seek migration provided they have the right capabilities (skills required, financial means, migration policies, etc.). On the impact of migration, our second empirical estimation gives evidence of a positive impact through remittances on the development of the home countries. The models show the positive contributions of remittances towards development through two main channels: capital investment and human capital (education and health). These two channels are believed to achieve long-term development of the home countries. At the micro level, we look at the mechanism of this impact at the household level, addressing the case study of Egypt. Our third models give evidence of the importance of these remittances in increasing both education and health status of the recipients’ households’. These findings are believed to make a contribution towards the understanding of this complex relation between migration and development

Abstract:
Em Portugal, a heráldica enquanto ciência, técnica e arte há muito que se preocupa com a questão da representação e identificação gráfica das cidades e das autarquias, servindo a sociedade de forma abrangente. As cidades ganharam na década de trinta do século XX, uma estruturação gráfica no sentido da sua uniformização, através dos brasões municipais, os quais se mantém ainda hoje como elemento gráfico de destaque no protocolo autárquico. Símbolos das cidades, os brasões são usados em toda a comunicação institucional e promocional do município. Contudo, nas duas últimas décadas muitas cidades e municípios sentiram necessidade de se afirmarem nesta matéria e, independentemente do sistema e regras heráldicas existentes, criaram e adoptaram uma nova identidade visual que as distingue das restantes. O presente estudo centra-se na cidade de Évora, na sua história, tradição, património, cultura e no brasão do município. Vivemos hoje numa sociedade que se confronta com os mais diversos problemas e por isso os órgãos de gestão autárquica e cidades estão diariamente perante novos desafios e um ambiente fortemente competitivo, sendo que essa concorrência criou a necessidade de se requalificarem em termos de imagem e comunicação, de modo a atrair mais população e investimento. É imperativo que a cidade de Évora se diferencie de outras, através de um activo importante, o reconhecimento de que é Património da Humanidade, o que terá reflexos obrigatoriamente na sua identidade visual. Com este estudo, serão identificados diversos problemas do brasão de armas da cidade de Évora e tentar-se-á uma clarificação da sua aplicação na construção da identidade da cidade e do município. O brasão da cidade é um símbolo histórico e deve ser preservado, uma vez que nos conta parte da narrativa da cidade, neste trabalho serão identificados vários casos de utilização indevida e adulteração do brasão. Assim, e porque se considera um símbolo institucional, será proposto que a utilização deste seja apenas de carácter protocolar, com a intenção assumida de determinar uma nova proposta de marca/identidade visual para o município, onde está incluída uma campanha promocional, com os suportes técnicos passiveis de utilização na estratégia de marketing e publicidade; ### Abstract: In Portugal, the heraldry as a science, technique and art have long been concerned with the question of representation and graphical identification of cities and municipalities, serving society in a broad sense. Most cities gained during the 30s of the twentieth century, a graphical structuring towards its standardization, through the use of the municipal coat of arms, which still applies today as graphic image in the municipal protocol. As symbol of the cities, generally the Coat of Arms are used in all the municipal communication tools, either institutional or promotional. However, in the last two decades, most cities and municipalities felt the need to affirm themselves on this subject and, regardless of the existing heraldic rules and system, created and adopted a new visual identity distinguishing themselves from one another. The present study is focused on the city of Évora, its history, tradition, heritage, culture and coat of arms. Today, we’re living in a society dealing with several problems and therefore the local authorities and cities daily face new challenges in an extremely competitive environment, competition which created the need for requalification in terms of image and communication, in order to attract more population and investment. It’s imperative that the city of Évora distinguishes itself from other cities through an important active, the recognition of the label of World Heritage, which will be necessary reflected in its visual identity. This study identifies various problems on the Coat of Arms of the city of Évora and will also try to clarify its use in the construction of the identity of the city and municipality. The Coat of Arms of the city it’s an historic symbol which must be preserved, it tell us something about the story of the city. This study will also identify several cases of misuse and adulteration of the Coat of Arms. Thus, and because it is considered an institutional symbol, it will be proposed its use only in protocol and institutional communication, with the firm intention of determining a new proposal for brand/visual identity for the Municipality, to be used specifically in promotion campaigns, with the necessary technical supports liable to be used in the marketing strategy and advertising.

Abstract:
Our world is characterized by growing diversity and complexity, and the effort to manage our affairs in a good way becomes increasingly difficult. This is true for all spheres of life, including culture, economy, technology, science, politics, environment and daily grind. A corresponding development occurs to our understanding of the brain, which is the crucial organ to keep track of everything. The amount of domain specific findings about this organ grows dramatically, what takes preferably place by highly specialized research. But the holistic understanding of the brain is rather more challenged than supported by this development, resulting in a huge lack of knowledge on the systemic level of the neurosciences. Eckhard Schindler faces this dilemma by introducing a macro model of the brain.

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária
A higiene oral, baseada na escovagem dentária sinergicamente com os dentífricos, tem vindo a ser usada há dezenas de anos por todo o mundo. Os seus princípios baseiam-se na remoção de restos alimentares e recuperação de um hálito fresco. Contudo, os seus grandes benefícios aumentam na remoção de grande parte da placa bacteriana, assim como do aporte de flúor para proteção contra a cárie dentária. Num contexto de crise económica e com o crescimento das grandes superfícies de distribuição que levaram ao aparecimento dos denominados produtos de marca branca, os hábitos na aquisição de dentífricos poderão estar a sofrer alterações, levando os consumidores a preferirem estes produtos pelo facto dos preços mais baixos. Neste sentido, este trabalho propôs-se a avaliar o consumo e tendência dos dentífricos, correlacionando a situação profissional dos consumidores e medindo o seu grau de confiança e satisfação com os dentífricos que usam diariamente. Para tal, foi efetuado um inquérito à população portuguesa e efetuaram-se análises laboratoriais aos principais dentífricos de marcas brancas e marcas comerciais vendidos em Portugal, de forma a quantificar a concentração total de flúor e verificar se estes estão de acordo com as normas comunitárias. Em média, todos os dentífricos continham as concentrações de flúor rotuladas e de acordo com as recomendações da American Dental Association e Comissão Europeia. Demonstrou-se que 72,7% dos inquiridos não usam para a sua higiene oral dentífricos de marca branca, e destes 62,4% referem Colgate® como a sua pasta de eleição. A dominar as marcas brancas com 3,9% de quota de marcado está a Continente®, seguida da Dentalux Lidl®. No entanto 6,2% dos consumidores reportaram iniciar o seu consumo há menos de um ano, o que demonstra um aumento de 67,7% face aos que os usam há mais tempo, transparecendo assim a confiança e satisfação no seu consumo. Das diferenças das formulações entre dentífricos, concluímos que todas são seguras para o seu uso diário e não colocam em risco a saúde oral dos seus consumidores em termos de flúor, salientando que as marcas brancas tendem a usar parabenos, contrariamente às de marca comercial. O uso simultâneo de monofluorfosfato e fluoreto de sódio demonstram grande benefício, no entanto carecem de mais estudos que possam afirmar esta relação. Oral hygiene, based on tooth brushing synergistically with toothpastes, has been used for decades throughout world. Its principles are based on the removal of food residues and recovering a fresh breath, however the great benefits are in the increase of the removal of much of the bacterium plaque, as well as the contribution of fluoride to protect against dental caries. In a context of economic crisis and the growth of large areas of distribution that led to the appearance of so-called white label products, the purchasing habits of toothpaste may be undergoing changes, leading consumers to prefer these products to the detriment of their low prices. In this sense, this study is aimed to assess the development of consumption and preference of toothpaste, correlating the consumers' employment situation and measuring their degree of confidence and satisfaction with the toothpaste they use daily. For such a national observation was made to the Portuguese population and laboratory tests conducted to the main toothpastes, white brands and trademarks ones, sold in Portugal in order to quantify the total concentration of fluoride and verify that they were in line with EU standards. On average, all toothpastes are labeled and containing the fluoride according to the recommendations of the European Commission and American Dental Association. It was demonstrated that 72,7% of the people inquired did not use a white label toothpaste in their oral hygiene, and 62,4% refer Colgate® to your folder choice. Dominating the white labels with 3,9% of share are the Continente® Supermarkets, then the Dentalux Lidl® Superrnarkets. However, 6,2% of the consumers reported starting their consumption to less than a year which shows an increase of 67,7% compared to those using them for a long time, showing confidence and satisfaction in their consumption. In the differences between the forrnulations of toothpastes, we conclude that all are safe for daily use and do not jeopardize oral health for consumers in terms of fluoride, noting that the store brands tend to use paraben, contrary to commercial trademark. Simultaneous use of monofluorophosphate and sodium fluoride show great benefit, however, it requires further studies to affirm this relationship.

This research presents a study of identity through a reflexion towards coats of arms and brands of important higher learning institutions in Europe, North America and Brazil, their stories and cultures using the semiotic theory as the field of science.The methodology used is hybrid because it reconciles a research model that contemplates the biographic review and comprehends an investment in the field of visibility - characteristic of the visual semiotic in its structuring nature - thus prioritizing attention to identity codes that unveil the various symbols present in the coats of arms and brands of the universities, objects of this research. Its interdisciplinary dimension is present in its convergence between the methodology of a visual study and the cultural sphere that frames this look for the universities. Its objective is to accomplish an analysis of large university brands and through a structured study of its many forms of presentation, verify how these institutions establish communication with society through the symbols and in what way they have evidenced their brands throughout the years thus contributing with own their traditions, beliefs and behavior. The significant alterations to the shapes of the coats of arms and brands are highlighted in this research that dialogs with with the period's communication comprehended by the XX and XXI centuries and their distinct subjects. The results show that the brands transmit the regional and institutional culture and are in constant change. Minimal alterations in their visual identities give signs of the university's evolution and the history of their conquests and conflicts. Some brands present a strong tendency to advance to contemporary society's imagery, bringing to the brands languages that incorporate new production technologies and placement of images to accompany the continually updated visual codes while others remains with coats of arms that date back to the XIX century and continue to use the heraldry for the maintenance of institutional values determined since its origins.
Esta pesquisa apresenta um estudo de identidade visual através de uma reflexão voltada aos brasões e marcas de importantes Instituições de Ensino Superior europeias, norte americanas e brasileiras, suas histórias e culturas tendo como campo de ciência o estudo da teoria semiótica. A metodologia utilizada é híbrida justamente porque concilia um modelo de pesquisa que contempla a revisão bibliográfica e compreende um investimento no campo da visualidade própria da semiótica visual, em sua natureza estruturante priorizando, assim, atenção aos códigos identitários que desvelam os feixes simbólicos presentes nos brasões e marcas das universidades, objetos desta pesquisa. Sua dimensão interdisciplinar se dá na convergência entre a metodologia própria de um estudo visual e a esfera cultural que emoldura este olhar para as universidades. Seu objetivo é o de realizar uma análise das grandes marcas universitárias e por meio de um estudo estruturante de suas diversificadas formas de se apresentar, verificar como essas instituições estabelecem comunicação com a sociedade através de símbolos e de que maneira vem evidenciando suas marcas ao longo dos anos contribuindo assim com suas tradições crenças e costumes. As significativas alterações nas formas de seus brasões e marcas são realçadas nesta pesquisa que dialoga com as comunicações no periodo compreendio pelos séculos XX e XXI e seus distintos sujeitos. O resultado aponta que as marcas transmitem a cultura regional e instituicional e estão em constante mudança. As alterações mínimas em suas identidades visuais dão sinais das evoluções das universidades e as histórias de suas conquistas ou conflitos. Algumas marcas apresentam a forte tendência de avançar para a sociedade imagética contemporâena, trazendo para si linguagens que incorporam novas tecnologias de produção e veiculação de imagens para acompanhar os códigos visuais continuamente atualizados enquanto outras permanecem com brasões datados desde o século XIX e continuam a usar da heráldica para manutenção de valores institucionais determinados desde as suas origens.

Mestrado em Marketing
O presente trabalho debruça-se sobre o actual crescimento das marcas próprias no ramo alimentar, considerando nesta análise o contexto de crise económica prolongada que se vive actualmente, assim como outros factores associados a este tipo de marca, entre os quais o preço, qualidade e variedade. Foi realizado um questionário utilizando uma amostra de conveniência, recorrendo à técnica bola de neve ao qual responderam 140 pessoas que constituíram assim a amostra não aleatória usada neste estudo. As respostas recolhidas permitiram retirar conclusões sobre as opiniões e comportamentos de compra face aos produtos alimentares de marca própria. É inicialmente mostrado que a alteração no comportamento dos consumidores face às marcas brancas está em parte ligado à actual crise económica e, ao mesmo tempo, que esta conjuntura é favorável ao crescimento deste tipo de marcas. A questão do preço é igualmente abordada e é obviamente um dos principais factores com mais peso na decisão de compra do consumidor, onde as marcas brancas apresentam preços bastante mais reduzidos, mas não só. Depois, e apesar dos consumidores terem sido “obrigados” a alterar os seus hábitos de compra, também não é menos verdade que se um produto não oferecer a qualidade desejável o consumidor não o volta a comprar, e nesse ponto as marcas brancas no ramo alimentar e não só, melhoraram muito a sua qualidade, tendo agora o consumidor confiança nesses produtos. Outro dos pontos analisados relaciona-se com a variedade e se, há dez anos, os produtos de marca própria apresentavam uma oferta muito escassa e reduzida praticamente a bens essenciais, hoje, e em especifico no ramo alimentar, todas as categorias de produto apresentam a opção de marca do distribuidor. Da análise feita através das frequências e cruzamento das variáveis estudadas observou-se uma atitude favorável por parte dos consumidores em relação aos produtos alimentares de marca própria onde os respondentes valorizam factores como a qualidade, preço e variedade na decisão de compra.
The present work adresses the current growth of own brands in the food sector having in consideration the economic crisis that we currently live as well as other factors associated with this type of brand including the price, quality and variety. A questionnaire was carried out, which surveyed 140 persons that made up the study sample. The responses collected allowed conclusions on the opinions and purchasing behavior in relation to own labels food products. It is shown that the change in consumer behavior vis-à-vis own labels is in part connected to the current economic crisis, and that this situation is favorable to the growth of store brands. Since the own labels have, in general, much lower prices, this issue is also addressed and it is obviously a major factor with a strong weight in the purchasing decisions of consumers. Despite consumers being "forced" to change their buying habits, if a product does not offer desirable quality, the consumer will not buy it again. Own labels in the food sector and others, have greatly improved their quality, and gained the trust of the consumer in these products. Another point raised in this thesis relates to variety. For over ten years, own label products had a very scanty supply, and reduced almost to essential goods. Today in the food sector all product categories have the own brand option from the distributer. From analysis through frequencies and crossing of variables, it was observed a favorable attitude among consumers towards own labels food products, where the value factors such as quality, price and variety emmerged as major factor in the purchase decision of consumers.

Their relationship with the philosopher from ephes "who wrote like a poet" (suidas, byzantine literary encyclopedia) is examined for the first time in this study. These poets' writings were based on a vision of the world as a unity of contrasts - much of what they tried to express took this vision as a point of departure. It is in this concept of uninterrupted movement and transformation that the essence of poetic activity resides: this research is oriented towards the discovery of the points where poetry and philosophy meet. One of the titles ascribed to heraclitus' work was "the muses" (diogenes laertius, 3rd century a. D. ), a title that would be justified by the book's influence on later poets- latin, english and spaniards in the baroque, german in the xviii century and poets of xxth century. Heraclitus's enigmatic fragments would be reinvented by these later

Abstract:
Les escoles de negocis han esdevingut, sobretot a partir del procés de globalització neoliberal iniciat en els anys 1980, en centres de poder on es formen professionals que ocupen llocs rellevants en les noves estructures empresarials, econòmiques i polítiques. La darrera crisi econòmica global de principis del segle XXI ha qüestionat aquest neoliberalisme ensenyat en les escoles de negocis i, en conseqüència, la legitimitat d’aquests centres educatius per guiar els camins econòmic, social i polític de la societat mundial. Paral•lelament al procés de globalització neoliberal, la tècnica i tecnologia modernes han canviat la manera com entenem la societat, les empreses, la ciència i el planeta, essent les noves tecnologies de la informació el paradigma d’aquesta nova societat global del segle XXI. En el treball presentem la tècnica com un element creat per l’home que, a la vegada, el defineix i, consegüentment, en determina el seu coneixement i la seva llibertat. Els interessos econòmics creats a partir de la Revolució Industrial són la clau per entendre l’expansió de la tècnica i de la tecnologia modernes i, en aquest sentit, la tècnica educativa ha tendit, per aquestes mateixes motivacions econòmiques, a l’especialització dels coneixements. Partint d’aquesta realitat, el treball mostra la necessitat que la tècnica educativa actual potenciï el que anomenem coneixement reflexionat, que és diferent a l’acumulació d’informació, i que definim com el component clau de l’economia moderna globalitzada, una economia que té com element característic i diferenciador l’aplicació del coneixement individual i col•lectiu en aparells de generació de coneixement, que, al seu torn, són fruit de la revolució de les tecnologies de la informació. Els canvis que la tècnica i ciència modernes han provocat fan necessari estudiar com funciona la tècnica educativa d’avui i quin tipus de coneixement necessitem les persones per construir la nostra pròpia llibertat. Els descobriments moderns del funcionament de la memòria humana i la plasticitat cerebral són fonamentals per elaborar coneixement reflexionat a escoles i universitats. A més, el moment actual d’incertesa social en el marc de la nova societat noosfèrica moderna fa inevitable la necessitat que en els centres educatius es formin persones amb unes noves habilitats i fortaleses que els permetin viure lliurement en la concepció moderna de l’espai i del temps. Per tot plegat, en el treball defensem que els objectius de les escoles de negocis han de ser responsables amb les necessitats socials i econòmiques mundials i plantegem una necessària legitimació de les causes socials i econòmiques que es tracten en els seus plans d’estudis, els quals, com demostrem, són homogenis arreu del planeta i emmotllats als criteris de rànquings diversos publicats en revistes especialitzades. Com a conclusió, proposem un programa transdisciplinar que anomenem Sòcrates per a potenciar el coneixement reflexionat entre els alumnes i ajudar a crear professionals amb personalitat i ètica d’acord a les necessitats socials i econòmiques de cada moment i regió.
Las escuelas de negocios se han convertido, sobre todo a partir del proceso de globalización neoliberal iniciado en los años 1980, en centros de poder donde se forman profesionales que ocupan puestos relevantes en las nuevas estructuras empresariales, económicas y políticas. La última crisis económica global de principios del siglo XXI ha cuestionado este neoliberalismo enseñado en las escuelas de negocios y, en consecuencia, la legitimidad de estos centros educativos para guiar los caminos económicos, sociales y políticos de la sociedad mundial. Paralelamente al proceso de globalización neoliberal, la técnica y tecnología modernas han cambiado el modo cómo entendemos la sociedad, las empresas, la ciencia y el planeta, siendo las nuevas tecnologías de la información el paradigma de esta nueva sociedad global del siglo XXI. En el trabajo presentamos la técnica como un elemento creado por el hombre que, a la vez, lo define y, consecuentemente, determina su conocimiento y su libertad. Los intereses económicos creados a partir de la Revolución Industrial son la clave para entender la expansión de la técnica y de la tecnología modernas y, en este sentido, la técnica educativa ha tendido, debido a estas mismas motivaciones económicas, a la especialización de los conocimientos. Partiendo de esta realidad, el trabajo muestra la necesidad que la técnica educativa actual potencie lo que llamamos conocimiento reflexionado, que es diferente a la acumulación de información, y que definimos como el componente clave de la economía moderna globalizada, una economía que tiene como elemento característico y diferenciador la aplicación del conocimiento individual y colectivo en aparatos de generación de conocimiento, que a su vez, son fruto de la revolución de las tecnologías de la información. Los cambios que la técnica y ciencia modernas han provocado hacen necesario estudiar cómo funciona la técnica educativa de hoy y qué tipo de conocimiento necesitamos las personas para construir nuestra propia libertad. Los descubrimientos modernos del funcionamiento de la memoria humana y la plasticidad cerebral son fundamentales para elaborar conocimiento reflexionado en escuelas y universidades. Además, el momento actual de incertidumbre social en el marco de la nueva sociedad noosférica moderna hace inevitable la necesidad de que en los centros educativos se formen personas con unas nuevas habilidades y fortalezas que les permitan vivir libremente en la concepción moderna del espacio y del tiempo. Por todo ello, en el trabajo defendemos que los objetivos de las escuelas de negocios deben ser responsables con las necesidades sociales y económicas mundiales y planteamos una necesaria legitimación de las causas sociales y económicas que se tratan en sus planes de estudios, los cuales como demostramos, son homogéneos en todo el planeta y moldeados a los criterios de rankings diversos publicados en revistas especializadas. Como conclusión, proponemos un programa transdisciplinario que llamamos Sócrates para potenciar el conocimiento reflexionado entre los alumnos y ayudar a crear profesionales con personalidad y ética de acuerdo a las necesidades sociales y económicas de cada momento y región.
Business schools have become, particularly from the neoliberal globalization process that started in the 1980's, centers where professionals are trained to take up important places in new business, economic and political structures. The last global economical crisis of the early twenty-first century has questioned this neoliberalism taught in business schools and, consequently, the legitimacy of these educational centers to guide the global economic, social and political paths of the world. Hand in hand to the process of neoliberal globalization, techniques and modern technology have changed the way we understand society, business, science and the world. They have become the new information technology paradigm of the new 21st century global society. At work we present the technique as something created by man which in turn is defined and thus determines his knowledge and freedom. The economic interests originated during the Industrial Revolution are the key to understanding the widespread of technique and modern technology. Besides, in this sense, teaching techniques have led to the specialization of knowledge by the same reason. Bearing this in mind, the study shows the need for the current teaching techniques to enhance what we call knowledge through thought, which is different to information accumulation and defined as the key component of the modern globalized economy. This economy has as a characteristic and differentiating feature the application of individual and collective knowledge into knowledge-generating devices, which, in turn, are the result of the revolution of information technology. The changes that modern technique and science have caused require study how current teaching techniques work and what kind of knowledge do we humans need to build our own freedom. Modern discoveries on human memory and brain plasticity are essential to develop knowledge through thought in schools and universities. In addition, the current uncertainty in the social frame of the new noospherical modern society makes it unavoidable to ignore the need in schools to train people with new skills and strengths that allow them to live freely in the modern conception of space and time. All in all, the paper argues that the goals of the business schools should be responsible for the global social and economic needs and proposes the necessary legitimation of the social and economic roots treated in their curricula which, as shown, are homogeneous across the globe and fitting the criteria of different rankings published in specialized journals. In conclusion, we propose a transdisciplinary program named Socrates as to bolster knowledge through thought among students and help to create professionals with ethics and personality according to the social and economic needs of each time and region.

Abstract:
Introdução: a cintilografia cardíaca com MIBI-99mTc sincronizada ao eletrocardiograma (gated SPECT) avalia integridade celular, perfusão miocárdica e função global e regional do ventrículo esquerdo (VE). A terapia de ressincronização cardíaca (TRC) pode melhorar os sintomas de insuficiência cardíaca (IC), mas seus benefícios sobre a função do VE são menos pronunciados. Objetivos: avaliar se as mudanças na captação miocárdica do MIBI-99mTc após a TRC estão associadas à melhora clínica, à redução do QRS ao eletrocardiograma e ao desempenho do VE e se a gated SPECT adiciona informação na seleção e acompanhamento de pacientes para a TRC. Método: trinta pacientes (idade media 59 ± 11 anos, 47% masculinos) com miocardiopatia dilatada não isquêmica, IC classe funcional III ou IV da New York Heart Association com tratamento medicamentoso otimizado, bloqueio de ramo esquerdo e fração de ejeção do ventrículo esquerdo (FEVE) inferior a 35% participaram deste estudo. Foram avaliados pré e três meses após TRC as seguintes variáveis: classe funcional de IC, duração do QRS, FEVE pela ecocardiografia, captação miocárdica do MIBI-99mTc (%) ao repouso e após estresse com adenosina, volumes diastólico (VDF) e sistólico finais (VSF) do VE, motilidade e espessamento regionais nas paredes do VE pela Gated SPECT. Após TRC, os pacientes foram divididos em dois grupos de acordo com a melhora na FEVE: grupo 1 (G1=12 pacientes) com aumento 5 pontos absolutos; e grupo 2 (G2=18 pacientes) sem aumento significante. Resultados: após TRC, ambos os grupos melhoraram significantemente a classe funcional de IC, reduziram QRS e aumentaram a captação miocárdica do MIBI-99mTc nas paredes ântero-septal e ínfero-septal. Apenas G1 apresentou mudanças favoráveis no VDF, VSF, motilidade e espessamento regionais do VE. Pré TRC, pela análise univariada, o VDF e ESV foram estatisticamente maiores no G2 em relação ao G1 (VDF: 477 ± 168 mL vs. 276 ± 94 mL, p<0,001; VSF: 401 ± 154 mL vs. 220 ± 85 mL, p<0,001, G2 e G1, respectivamente). A captação miocárdica do MIBI-99mTc foi menor no G2 em relação ao G1 nas paredes anterior (60 ± 10% vs. 67 ± 7%, p=0,049, repouso) e inferior (48 ± 10% vs. 59 ± 11%, repouso, e 47 ± 10% vs. 58 ± 9%, p=0,003, após estresse). A soma dos escores de hipocaptação após estresse foi significantemente maior no G2 em relação ao G1 (14 ± 9 e 9 ± 4, G2 e G1, respectivamente, p=0,039). Pela análise multivariada, o VDF foi o único preditor independente de aumento na FEVE após terapia, p=0,01. O ótimo ponto de corte do VDF pela curva ROC para predizer melhora na FEVE após terapia foi 315 mL com sensibilidade de 89% e especificidade de 94%. Conclusões: A TRC aumentou a captação miocárdica regional de MIBI-99mTc, melhorou a classe funcional de IC e reduziu QRS independentemente da melhora do desempenho cardíaco. Após TRC, o aumento da FEVE ocorreu em corações menos dilatados e com uma maior captação miocárdica regional do MIBI-99mTc, principalmente na parede inferior
Background: gated myocardial scintigraphy with 99mTc-MIBI (gated SPECT) evaluates myocyte integrity, myocardial perfusion and global and regional left ventricular (LV) function. Cardiac resynchronization therapy (CRT) may improve heart failure (HF) clinical symptoms, but its benefits for LV function are less pronounced. Objectives: we assessed whether changes on myocardial 99mTc-MIBI uptake post-CRT are related to improvement in clinical HF symptoms, reduction in QRS duration and improvement in LV performance, and whether gated SPECT with 99mTc-MIBI adds information to selection and follow-up of patients undergoing CRT. Methods: thirty patients (mean age 59 ± 11, 47% male) with nonischemic dilated cardiomyopathy, chronic HF in New York Heart Association functional class III or IV with optimized clinical treatment, left bundle-branch block, and LV ejection fraction (LVEF) inferior to 35% participated to this study. Pre- and 3 months post-CRT, the variables analyzed were: HF functional class, QRS duration, LVEF by echocardiography, myocardial 99mTc-MIBI uptake (%) at rest and after adenosine stress, LV end-diastolic (EDV) and end-systolic volumes (ESV), regional LV motion and thickness by gated SPECT. Post-CRT, patients were divided into 2 groups according to LVEF improvement: group 1 (G1=12 patients) with increase in LVEF5points and group 2 (G2=18 patients) without significant increase. Results: post-CRT, both groups improved significantly in HF functional class, reduced QRS width and increased antero-septal and infero-septal wall 99mTc-MIBI uptake. Only G1 had favorable changes in EDV, ESV, and LV regional motion and thickness. Pre- CRT, by univariate analysis, EDV and ESV were statistically higher in G2 compared with G1 (EDV: 477 ± 168 mL vs. 276 ± 94 mL, p<0.001; ESV: 401 ± 154 mL vs. 220 ± 85 mL, p<0.001, G2 and G1, respectively). Myocardial 99mTc-MIBI uptake was lower in G2 compared with G1 in the anterior wall (60 ± 10% vs. 67 ± 7%, p=0.049, at rest) and inferior wall (48 ± 10% vs. 59 ± 11%, at rest, and 47 ± 10% vs. 58 ± 9%, p=0.003, after adenosine stress). Summed stress score was significantly higher in G2 compared to G1 (14 ± 9 vs. 9 ± 4, G2 and G1, respectively, p=0.039). By multivariate analysis, EDV was the only independent predictor of LVEF increase posttherapy, p=0.01. By ROC curve, optimal EDV cutoff point was 315mL with 89% of sensitivity and 94% of specificity. Conclusions: CRT increased myocardial 99mTc- MIBI uptake, improved HF functional class, and reduced QRS width independently of LV performance improvement. Post-CRT, LVEF increase occurred in hearts less dilated showing higher regional myocardial 99mTc-MIBI uptake, mainly in the inferior wall

Abstract:
The term &quot;pattern formation&quot; refers to the process by which order unfolds in development. The present thesis deals with a particular aspect of molecular pattern formation during vertebrate embryogenesis. The model system in the focus of this study is the zebrafish, Danio rerio. In the early developmental phases of the zebrafish, Fibroblast growth factors (Fgfs) are involved in the molecular patterning of various tissues, including two regions of the brain, the forebrain and the midbrain-hindbrain region, affecting cellular processes as diverse as cell proliferation, differentiation, and axonal targeting. The goal of this study was to better understand the mechanisms by which Fgf signaling regulates pattern formation and embryogenesis. I addressed this question on several levels, investigating the extent of intracellular signaling (MAPK activation) relative to sources of Fgf expression, and the transcriptional responses of cells to Fgf signaling during embryogenesis. By a macroarray analysis, I identified putative transcriptional targets of Fgf signaling in late gastrulation, providing a set of molecules that are likely to act as functional players in relaying the patterning information encoded by Fgf signals. Among those are the secreted signaling molecules Chordin and Wnt8, as well as Isthmin, a novel secreted molecule that I found capable to interfere with anterior embryonic patterning. In addition, I identified two ETS domain transcription factors, Erm and Pea3, which constitute bona fide integrators of FgfR signaling. By gain- and loss-of-function studies, I demonstrate that transcript levels of erm and pea3 are tightly regulated by Fgf signaling. Detailed analysis of the expression patterns of erm and pea3 along with other Fgf target genes also provides evidence for a differential read-out of Fgf concentration in the embryo, consistent with a role of Fgf as a vertebrate morphogen. The discovery of novel molecular components downstream of Fgf receptor activity paves a way to characterize previously unknown or underestimated developmental roles of Fgfs in the molecular patterning of the forebrain, the eye and parts of the neural crest.

Abstract:
Introdução: A terapia de ressincronização cardíaca (TRC) é um tratamento recomendado pelas principais diretrizes mundiais para pacientes com insuficiência cardíaca congestiva (ICC), disfunção ventricular esquerda (FE <= 35%), com tratamento otimizado e distúrbio da condução intraventricular, principalmente pelo ramo esquerdo. Entretanto, 30%-40% dos pacientes selecionados não respondem ao tratamento. As razões desse insucesso não são completamente conhecidas. Existe, portanto, necessidade de desenvolvimento de índices multifatoriais para melhor selecionar e acompanhar a evolução e o prognóstico destes pacientes. Objetivo: Elaborar modelos preditores de risco de óbito cardíaco ou transplante (Tx), em diferentes fases da TRC. Métodos e Casuística: Estudo observacional, prospectivo e analítico, com inclusão de 116 pacientes, entre 01/2008 a 03/2013, sendo 69,8% do sexo masculino, com CF III (68,1%) e IV ambulatorial (31,9%), com BRE em 71,55% e com idade de 64,89 ± 11,18 anos e fração de ejeção (FE) de 29%. Avaliações foram feitas no período pré-implante (tempo 1), 6-12 meses (tempo 2) e 18-24 meses (tempo 3) e correlacionadas com a mortalidade cardíaca/Tx no final do seguimento. Foram estudadas variáveis clínicas, eletrocardiográficas e ecocardiográficas e realizadas análises de regressão de Cox e regressão logística, com a construção da curva ROC. As curvas de sobrevidas foram realizadas pelo método de Kaplan-Meier e comparadas pelo log-rank. Modelos e escores foram elaborados pelas pontuações do \"hazard ratio\", utilizado como variável independente no modelo de regressão logística. Resultados: Ocorreram 29 (25%) óbitos/Tx durante o seguimento de 34,09 ± 17,9 meses. A mortalidade cardíaca/Tx foi de 16,3 % (19 pacientes). Seis pacientes foram transplantados durante o tempo do estudo. No período préimplante (tempo 1), a presença de disfunção de ventrículo direito (VD), FE < 25% e o uso de altas doses de diuréticos (dois ou mais comprimidos de furosemida) mostraram-se com valor independente, com aumento de risco de óbito cardíaco/Tx de 3,9; 4,8 e 5,9 vezes, respectivamente. No tempo 2 (1° ano), as variáveis disfunção de VD, altas doses de diuréticos e internações por ICC foram as variáveis significativas, com aumento de risco 3,5; 5,3 e 12,5 respectivamente. No tempo 3 (2° ano), as variáveis disfunção de VD e classe funcional III/IV foram significativas no modelo multivariado de Cox, com aumento de risco de 12,1 e 7,7. As acurácias dos modelos foram 84,6%; 93% e 90,5%, respectivamente. Conclusão: Os modelos preditores de óbito cardíaco desenvolvidos a partir de variáveis clínicas e ecocardiográficas, obtidas em diferentes fases da TRC, mostraram boa acurácia e podem ajudar na seleção, seguimento, definição de resposta e aconselhamento destes pacientes
Introduction: Cardiac resynchronization therapy (CRT) is indicated for patients with congestive heart failure (CHF), ejection fraction (EF) <= 35%, and bundle branch block. However, 30%-40% do not respond to CRT. Therefore, there is a need to develop multifactorial indexes to better select and follow these patients. Objective: This work aims to develop predictive models for the risk of cardiac death or transplantation (Tx) at different stages of CRT. Methods: We performed a prospective observational study of 116 patients, 69.8% males, functional class (FC) III (68.1%) and IV (31.9%), LBBB in 71.55%, age 64.89 ± 11.18 years. We studied clinical, electrocardiographic, and echocardiographic variables and performed Cox and logistic regression with ROC and Kaplan- Meier curves. Results: The cardiac mortality was 16.3% (19 patients) in the 34.09 ± 17.9 follow-up months. Pre-implantation, the right ventricular dysfunction (RVD), EF <25%, and the use of high doses of diuretics (HDD) increased risk of cardiac death or Tx of 3.9, 4.8, and 5.9 fold, respectively, and in the first year, the variables RVD, HDD, and hospitalizations for CHF increased risk of death of 3.5, 5.3, and 12.5, respectively. In the 2nd year, the variables RVD and FC III / IV (NYHA) were significant in the multivariate Cox model. The accuracies of the models were 84.6%, 93%, and 90.5%, respectively. Conclusions: Cardiac death predictive models were developed in different stages of CRT, and were based on the analysis of simple clinical and echocardiographic variables. The models showed good accuracy and can help in the selection and follow-up of these patients

Exame Público realizado em 21 de Julho de 2017
Em mercados cada vez mais competitivos, a marca e o seu valor assumem, nos dias de hoje, uma importância fundamental na gestão das empresas, constituindo um dos seus ativos principais. Desta forma, a presente dissertação nasce do crescente interesse pelo estudo da marca e do seu valor, assim como da necessidade de aprofundar conhecimentos sobre esta temática dada a sua relevância. Neste contexto, o tema em estudo consiste no Valor da Marca do Produtor Versus Marca Branca e tem como objetivo avaliar os fatores que influenciam o valor da marca na ótica do consumidor, tendo em conta as dimensões do brand equity, nomeadamente a responsabilidade social, a lealdade à marca e o amor à marca. Para o efeito, a marca escolhida foi a da água São Martinho. Este estudo divide-se em quatro componentes principais. A primeira refere-se ao estudo da arte sobre os temas nomeados, seguida da segunda componente que incide sobre a metodologia baseada num inquérito por questionário online. Este método quantitativo foi aplicado a uma amostra não probabilística por conveniência e que é constituída por 279 indivíduos. A terceira componente destina-se à análise dos resultados e, a quarta, à discussão dos mesmos. Após a análise dos dados foi possível verificar que as variáveis do estudo conferem valor à marca São Martinho. Ficou ainda comprovado que os inquiridos adquirem cada vez mais produtos de marcas brancas reconhecendo a sua qualidade
In increasingly competitive markets, the brand and your value has, today, an essential role in the management of the companies constituting one of its main assets.

Relatório de estágio de mestrado em Ciências da Comunicação (área de especialização em Audiovisual e Multimédia)
Este relatório surge como resultado de um estágio curricular na LK Comunicação. Além de refletir sobre a experiência obtida durante esse tempo em empresa, pretende também aprofundar o estudo sobre a relação entre o vídeo, mais concretamente o promocional, e o universo online. Serão refletidas quais são as caraterísticas que um vídeo orientado para a comunicação Web precisa conter para que consiga impacto junto do utilizador. O online é cada vez mais o principal modo de comunicação entre o ser humano, quer seja a nível pessoal, quer seja a nível empresarial, sendo atualmente o Facebook o seu expoente máximo. O vídeo, por outro lado, é uma das técnicas mais utilizadas para a promoção de marcas, quer pelo seu dinamismo ou por a sua produção ser cada vez mais simples, sendo que no contexto Web, atingem o máximo reconhecimento quando se tornam virais. Como pontochave desta relação está o público e todas as variáveis que o constituem. Não sendo uma massa amorfa, é sempre difícil prever a sua reação às ações de comunicação e mais concretamente, aos vídeos. Assim, tendo como ponto de partida o caso de uma das várias marcas e eventos trabalhados durante o tempo de estágio, a Noite Branca – Braga, será estudado o papel dos vídeos promocionais como ação comunicativa de uma marca/evento e a sua influência junto do público.
This report is the result of an internship in LK Communicação. In addition to reflecting on the experience gained during the time spent in the agency, it also intends to deepen the study of relationship between video – specifically, promotional videos -, and the online universe. It will speculate what characteristics a video oriented to Web communication must contain to have impact with the user. Online is increasing as the primary mode of communication between human beings, whether on a personal level, whether at the enterprise level, being Facebook its peak. The video, on the other hand, is one of the most widely used techniques for promoting brands, either by its momentum or because the production is much simpler nowadays, whereas in the Web context, it reaches maximum recognition when it becomes viral. The key point of this relationship is the public and all the variables that constitute it. Not being an amorphous mass, it’s always difficult to predict their reaction to communication actions and, more specifically, videos. Like so, taking as starting point one of several brands and events worked during the internship, Noite Branca – Braga, this report studies the role of promotional videos as communicative actions of a brand / event and its influence on the public.

Abstract:
As inovações tecnológicas utilizadas para entretenimento em ambiente digital, proporcionaram importantes mudanças na forma de consumo de produtos e informações, ao longo do tempo. O consumidor digital, atualmente, utiliza-se de múltiplas plataformas para criar novas experiências junto à grandes marcas, o que se torna importante compreender como cada indivíduo, seja ele nascido dentro ou fora deste contexto digital, vem se adaptando à essa nova experiência de consumo do mercado do entretenimento. O presente estudo explora, então, temas como marketing geracional e de experiência, em ambiente digital, tendo como objetivos geral compreender o consumo de filmes musicais da Disney, em contexto digital, pelas gerações baby boomers e millennials. A escolha da marca Disney e dos filmes “A Branca de Neve e os Sete Anões” e “A Pequena Sereia” como objeto de análise se sustenta, em primeiro lugar, no pioneirismo de seu criador Walt Disney no campo Audiovisual mundial e, também, para o campo da Comunicação e Marketing. Além disto, Disney é uma marca centenária, premiada, que constantemente se reinventa para atrair um público cada dia maior e mais exigente. Em segundo lugar, os filmes selecionados são clássicos musicais que se perpetuam por várias gerações em versões atualizadas seguindo o padrão da marca. Trata-se de uma pesquisa sobre a marca Disney através de um estudo qualitativo, que utilizou da técnica de entrevistas semiestruturadas com indivíduos das duas gerações estudadas. A Análise de Conteúdo deu suporte para a compreensão dos resultados, que serão apresentados no decorrer deste trabalho. Estes resultados apresentaram concordância com os aportes teóricos, respondendo ao objetivo geral, onde se compreende que o consumo de filmes musicais, em contexto digital, apresenta diferenças entre o consumo receptor dos baby boomers e o prosumer dos millennials.
Technological innovations used for entertainment in a digital environment, provided important changes in the way products and information, over time. The digital consumer currently uses multiple platforms to create new experiences with major brands, making it important to understand how each individual, whether born within or outside this digital context, has adapted to this new consumer experience within the entertainment market. This study explores themes such as generational and experience marketing, in a digital environment, with general objectives of understanding the consumption of Disney musical films, in a digital context, by the “baby boomers” and millennials generations. The Disney brand and the films “Snow White and the Seven Dwarfs” and “The Little Mermaid” were chosen as objects of analysis for the pioneering spirit of their creator Walt Disney and his innovation in the worldwide field of Communication and Marketing. Disney is a century-old award-winning brand that constantly reinvents itself to attract an increasingly larger and more demanding audience. The films selected are classic musical films that have been enjoyed by multiple generations in updated versions following the brand's standard. This is a qualitative study which relies on interview with people from the baby boomer and millennial generations. Content Analysis helps with understanding the results of this study. These results correspond with the theoretical foundation. In response to the principle objective, it was found that the digital consumption of musical films shows key differences between baby boomers as consumption receivers and millennials as prosumers.

Abstract:
Private Label Brands (PLB), which are sold under a retailers’ brand, demonstrate increasingly levels of quality and acceptance. National Brands (NB) are owned and advertised by a specific brand. Taste is one the most important factors of decision for consumers’ regarding food products. However, most research on this subject falls under the domain of traditional methods relying many times on inaccurate results, as it is not possible to fully measure and understand what consumers’ truly feel. The experience conducted for this dissertation (N=19) in an adequate laboratory with the use of Consumers Neuroscience methods, more specifically Electrodermal Activity, evaluated through blind and non-blind taste tests, the actual effect of taste on consumers’ Emotions (Arousal), Perceived Taste and Willingness to Buy. Valence was also measured through the Self-Assessment Manikin. Findings demonstrate that even though national brands are still perceived by consumers as superior, consumers’ willingness to buy will not necessarily be higher for national brands. The finding that consumers’ decision will not always be in favour for the product which is perceived of highest quality (i.e. NB), leads to the conclusion that the “quality gap” is fading and the two are increasingly equitable and is now crucial to tackle the “branding gap”.
Private Label Brands (PLB), vendidas sob marca dos retalhistas, demonstram cada vez melhores níveis de qualidade e aceitação. Por outro lado, National Brands (NB) são marcas de detidas e publicitadas por uma entidade específica. O sabor é o factor de decisão mais importante para os consumidores em relação aos produtos alimentares. No entanto, a maioria das pesquisas neste assunto enquadra-se no domínio dos métodos tradicionais dependendo muitas vezes de resultados imprecisos, uma vez que não é possível medir e perceber a nível fisiológico, o que os consumidores realmente sentem. A experiência conduzida para esta dissertação (N = 19) em laboratório adequado, LAPSO, com o uso de métodos de Consumer Neuroscience, mais especificamente Electrodermal Activity, avaliando através de testes de sabor em cenário cego e não cego, o efeito real do sabor nas Emoções dos consumidores (Excitação), Perceived Taste e Willigness to Buy (WTB). Valência também foi medida através do Self-Assessment Manikin (SAM). Os resultados demonstram que NB ainda são considerados pelos consumidores como superiores a nível de qualidade, porém o WTB dos consumidores não será necessariamente maior para NB. O resultado de que a intenção de compra dos consumidores nem sempre é favorável ao produto considerado de melhor qualidade (NB) leva à conclusão de que a "desigualdade da qualidade" está desaparecendo e que os dois são cada vez mais comparáveis, sendo agora crucial enfrentar a "desigualdade da marca".
