Narrativas do Brasil nas memórias de Pedro Nava

This thesis is a translation of work of the Brazilian doctor, Pedro da Silva Nava (1903-1984), in particular, his memoirs and chronicles, articulated with the writings of medicine history, aiming to defend that the autobiographical narratives are sources of research capable of promoting discussions on the expansion of the present at the confluence of complex and unequal society in constant changing process as the Brazilian. The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecléa Bosi, Ítalo Calvino, José Willington Germano, José Maria Cançado, Lev Vygotsky, Marilena Chauí, Paul Ricöeur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil

Gira Mundos : a Educação Ambiental no mito e o mito na Educação Ambiental

A Educação Ambiental constitui-se na relação entre a natureza e a cultura de modo indissociável das relações de poder e de saber. A pesquisa enreda-se na tendência da Educação Ambiental complexa, analisa os modos de fabricação das subjetividades impostas pelo discurso neocapitalista, investiga a racionalidade herdada da sociedade moderna e explora a lógica dos referenciais afrodescendentes, em específico as lógicas presentes nos Terreiros da Umbanda. Problematiza o mito na Educação Ambiental e a Educação Ambiental no mito a partir das orixalidades umbandistas. Adota a pesquisa narrativa dialogando com Tristão (2012), problematiza os processos de subjetivação a partir de Foucault (1996) e busca capturar os saberes sustentáveis da noosfera umbandista (MORIN, 2005c) influenciada por Deleuze e Guattari (1996-1997). Através das Giras, seu principal ritual, evidencia como essas lógicas são acionadas para a fabricação de novos modos de percepção da relação entre a cultura e a natureza. Contribuem, no processo de investigação para a produção dos dados, a realização de entrevistas abertas e semiestruturadas, o registro em cadernos de bordo, gravações em áudio e vídeo, fotografias e rodas de conversas em encontros com professores e alunos de uma escola pública, próxima aos Terreiros, onde problematiza os processos e mecanismos de exclusão e violência materializados em posturas discriminatórias e de negação da cultura afro-brasileira e o modo como essas experiências são partilhadas pelos professores e alunos no contexto de suas práticas. A aposta metodológica consiste em criar estratégias de narrar experiências da Educação Ambiental em espaços não formais, como os espaços dos Terreiros da Umbanda, e em espaços formais, como a escola, através das orixalidades em narrativas, na busca de zonas de confiança e na invenção de encontros mais solidários, por escutas mais sutis e híbridas, e de novos sentidos de alianças que dissolvam pontos de vistas e desestabilizem discursos do eixo dominante, como forma de exercício do pensamento para abertura de lógicas silenciadas historicamente. Conclui que lógicas complexas incluem as existências infames e obscurecidas pela lógica oficial e que lógicas complexas buscam ver os efeitos dos modos como nós próprios fomos constituídos. A fé-eco-lógica presente nas orixalidades em narrativas potencializa a desconstrução dos regimes de verdade e subverte a monocultura de lógicas.

Why aren't brand names regognized as intangible assets in the financial Statements? A study of the subjectivity of brand valuation

The goal of this paper is to determine and to quantify how subjective brand valuation is. To do so, we review the different valuation methods and apply the Hirose model to a sample of 20 US companies from the technology sector. Even if the results vary in function of the rankings we choose as a comparison, we may identify the trend that brands are usually overvalued in those rankings. It explains why internally generated goodwill (which includes brand names) is not recognized as an intangible asset in the financial statements.

Membrane-destabilizing activity of pH-responsive cationic lysine-based surfactants: role of charge position and alkyl chain length

Many strategies for treating diseases require the delivery of drugs into the cell cytoplasm following internalization within endosomal vesicles. Thus, compounds triggered by low pH to disrupt membranes and release endosomal contents into the cytosol are of particular interest. Here, we report novel cationic lysine-based surfactants (hydrochloride salts of N¿- and N¿-acyl lysine methyl ester) that differ in the position of the positive charge and the length of the alkyl chain. Amino acid-based surfactants could be promising novel biomaterials in drug delivery systems, given their biocompatible properties and low cytotoxic potential. We examined their ability to disrupt the cell membrane in a range of pH values, concentrations and incubation times, using a standard hemolysis assay as a model of endosomal membranes. Furthermore, we addressed the mechanism of surfactant-mediated membrane destabilization, including the effects of each surfactant on erythrocyte morphology as a function of pH. We found that only surfactants with the positive charge on the ¿-amino group of lysine showed pH-sensitive hemolytic activity and improved kinetics within the endosomal pH range, indicating that the positive charge position is critical for pH-responsive behavior. Moreover, our results showed that an increase in the alkyl chain length from 14 to 16 carbon atoms was associated with a lower ability to disrupt cell membranes. Knowledge on modulating surfactant-lipid bilayer interactions may help us to develop more efficient biocompatible amino acid-based drug delivery devices.

Phosphorylation regulates the microtubule-destabilizing activity of stathmin and its interaction with tubulin.

Stathmin is a regulator of microtubule dynamics which undergoes extensive phosphorylation during the cell cycle as well as in response to various extracellular factors. Four serine residues are targets for protein kinases: Ser-25 and Ser-38 for proline-directed kinases such as mitogen-activated protein kinase and cyclin-dependent protein kinase, and Ser-16 and Ser-63 for cAMP-dependent protein kinase. We studied the effect of phosphorylation on the microtubule-destabilizing activity of stathmin and on its interaction with tubulin in vitro. We show that triple phosphorylation on Ser-16, Ser-25, and Ser-38 efficiently inhibits its activity and prevents its binding to tubulin.

Identification of in vitro phosphorylation sites in the growth cone protein SCG10. Effect Of phosphorylation site mutants on microtubule-destabilizing activity.

SCG10 is a neuron-specific, membrane-associated protein that is highly concentrated in growth cones of developing neurons. Previous studies have suggested that it is a regulator of microtubule dynamics and that it may influence microtubule polymerization in growth cones. Here, we demonstrate that in vivo, SCG10 exists in both phosphorylated and unphosphorylated forms. By two-dimensional gel electrophoresis, two phosphoisoforms were detected in neonatal rat brain. Using in vitro phosphorylated recombinant protein, four phosphorylation sites were identified in the SCG10 sequence. Ser-50 and Ser-97 were the target sites for protein kinase A, Ser-62 and Ser-73 for mitogen-activated protein kinase and Ser-73 for cyclin-dependent kinase. We also show that overexpression of SCG10 induces a disruption of the microtubule network in COS-7 cells. By expressing different phosphorylation site mutants, we have dissected the roles of the individual phosphorylation sites in regulating its microtubule-destabilizing activity. We show that nonphosphorylatable mutants have increased activity, whereas mutants in which phosphorylation is mimicked by serine-to-aspartate substitutions have decreased activity. These data suggest that the microtubule-destabilizing activity of SCG10 is regulated by phosphorylation, and that SCG10 may link signal transduction of growth or guidance cues involving serine/threonine protein kinases to alterations of microtubule dynamics in the growth cone.

Subjectivity in the valuation : Case study on the Finnish biotechnology industry

The thesis combines valuation and behavioral economics literature, which is not common among the Finnish management accounting research. Furthermore, the valuation is studied in biotechnology context and those type of studies are rather rare as well. The thesis studies the valuation in the Finnish biotechnology industry. The concepts of behavioral finance are employed in the empirical part of the study to explore decision-makers’ behavior in valuation processes. The main interest of this study is to explore how subjectivity of a decision-maker affects the valuation in the biotechnology industry. The valuation is studied from two perspectives. First, what is the best valuation model for biotechnology companies suggested by the valuation literature? Second, how the valuation in biotechnology industry is done in practice and how the decision-makers subjectivity affects the valuation? The literature review aims at seeking the best valuation model. The real options were found to be the most suitable valuation model for biotechnology companies, especially in the early stages of product development. The real option’s ability to take the value of the inherent options into account results in theoretically most correct valuations. The only disadvantage is the model’s complexity when compared to other models, such as discounted cash flow models. The empirical part of the study consists of a case study, which examines the valuation practices of the Finnish biotechnology companies. When it comes to the valuation models used in practice, it was found that the companies were using rather simple valuation models, which was due to two reasons. First, the interviewees did not believe in the valuation models and second, they were familiar neither with the most sophisticated models nor with all the theoretical aspects of the models they were using. The material for the study was collected with theme interviews. Four CEO’s of highly successful Finnish biotechnology companies. Strong signs of the decision-makers’ subjectivity in valuation were observed. Most obvious were the signs of framing. Furthermore, herding, excessive optimism, and overconfidence were present. All the behavioral concepts observed most likely have a severe effect on the valuation. As a result, the valuation can easily become overly optimistic, which leads to overvalued investments and to continuation of already unprofitable projects. Framing had the strongest evidence. If the product being valued is framed successfully, the risk of overvaluation is high, thus a strong belief can justify almost any value.

"All The Best Cowboys Have Daddy Issues": [Post]Oedipal Fatherhood And Subjectivity In ABC's Lost

ABC's popular television series Lost has been praised as one of the most innovative programs in the history of broadcast television primarily due to its unique storytelling content and structure. In this thesis, I argue that in spite of its unconventional stances in terms of narrative, genre, and character descriptions, Lost still conforms to the conventional understanding of family, fatherhood, and subjectivity by perpetuating the psychoanalytic myth of the Oedipus complex. The series emphasizes the centrality of the father in the lives of the survivors, and constructs character developments according to Freud's essentialist and phallocentric conception of subjectivity. In this way, it continues the classic psychoanalytic tradition that views the father as the essence of one's identity. In order to support this argument, I conduct a discursive reading of the show's two main characters: Jack Shepherd and John Locke. Through such a reading, I explore and unearth the mythic/psychoanalytic importance of the father in the psychology of these fictional constructs.

Queering the Cross-Cultural Imagination: (Trans)Subjectivity and Wilson Harris's The Palace of the Peacock

Ce mémoire comprend deux volets : une étude théorique et un texte de création littéraire. Dans un premier temps, il s’agir d’étudier le rôle du désir dans la démarche thématique et philosophique employée par l’écrivain Wilson Harris dans son roman The Palace of the Peacock. Ainsi démonterons-nous dans le premier chapitre que Harris se sert – de façon paradoxale – du désir empirique pour faire valoir les limites mêmes de celui-ci. Nous aborderons dans le deuxième chapitre le rapport problématique qu’entretient, chez Harris, la subjectivité féminine avec la subjectivité masculine. En particulier, nous examinerons la représentation de ce rapport sous la forme de métaphores ayant trait à l’environnement et à l’anatomie. Nous avancerons que le caractère problématique que revêt le rapport entre subjectivités féminine et masculine dans le roman est en quelque sorte nécessitée par l’écriture même de Harris. Dans le troisième chapitre, nous prendrons part aux débats sur la poétique qui animent la littérature contemporaine afin de situer notre propre élan vers la création littéraire. En même temps, nous entreprendrons une tentative de récupération de certains des concepts théoriques formulés par Harris, en lien avec notre propre poétique. S’ensuivra notre projet de création littéraire, intitulé HEROISM/EULOGIES, qui constitue le quatrième et dernier chapitre du mémoire. Ce texte, extrait d’un projet d’écriture créative plus vaste, trace les mouvements d’un certain nombre de sujets à travers une Amérique imaginée.
