ANTROPOLOGIA TRANSCENDENTAL E CORRELAÇÃO : KARL RAHNER E PAUL TILLICH EM DIALOGO - UMA LEITURA INTERCONFESSIONAL DE MÉTODOS TEOLÓGICOS A PARTIR DA ONTOLOGIA EXISTENCIAL DE MARTIN HEIDEGGER

Esta tese de Doutorado procura estudar os métodos teológicos em diálogo, antropologiatranscendental de Karl Rahner e correlação de Paul Tillich, a partir da sistematização da ontologia existencial elaborada pelo jovem Heidegger em Sein und Zeit. Tanto num, como noutro método, o que se discute é a profundidade do ser, na sua possibilidade de aproximação em superação ao que não pode ser dito. Nesse caso, tanto a metafísica tomista, resgatada por Rahner, quanto a secularização protestante e o abismo do ser, enfatizado por Tillich, assumem a impossibilidade de se dizer o conteúdo do sagrado, exatamente por se situarem ou no inconceito da raiz ontológica (Rahner), ou no excesso de sentido do Ultimate Concern (Tillich). Dessas impossibilades, independente se um antes e depois (Rahner), ou se um depois e um antes em profundidade (Tillich), o que se tem é a pergunta ontológica como possibilidade da abertura do ser, nos dois casos sem conteúdo, para que a resposta , que também não responde, seja dada como (im)possibilidade do deslocamento do ser. No resgate da metafísica tomista, em Rahner, há um deslocamento a partir de um sentido, de certo modo linear , daí antropologia-transcendental. Já na leitura protestante de Tillich, o deslocamento se dá por uma dialética , o ser ameaçado pelo não-ser, como uma unidade rompida, daí correlação. A tese é apresentada em quatro capítulos. No primeiro há uma leitura de Heidegger, pela perspectiva da hermenêutica da compreensão. Já no segundo a reflexão se dá em busca da possibilidade da compreensão pela racionalidade ontológica na correlação, Paul Tillich, pela mediação do simbólico. No terceiro, seguindo as mesmas preocupações, se faz a leitura da epistemologia na racionalidade ontológica na antropologia -transcendental, Karl Rahner, pela mediação da pré-apreensão. O quarto capítulo apresenta temas decorrentes, e tradicionais da teologia, em diálogo a partir dos métodos.(AU)

EVOCAÇÃO POÉTICA : O velar e o desvelar da obra pictórica Menino morto de Cândido Portinari à luz das concepções de Paul Tillich e de Martin Heidegger sobre as artes

A arte sempre esteve presente entre os humanos como um grande mistério. Sua característica polissêmica nos desafia a pensá-la como algo sempre aberto. Isto é, livre para que os indivíduos a experimentem de formas diversas. Nossa intenção, ao escolher a tela Menino morto do pintor Cândido Portinari, é mostrar que o encontro com uma obra de arte é forçosamente atual, vivo, surpreendente, extraordinário... Não apenas como um mero objeto de prazer, mas, sobretudo, como possibilidades de desvelar experiências originárias, abrindo gamas de sentidos que ajudam os seres humanos a significar a própria existência. Para seguir na investigação, privilegiam-se, nesta dissertação, os estudos sobre as artes do teólogo Paul Tillich e do filósofo Martin Heidegger. Para Tillich, numa obra de arte deve-se buscar o que se esconde no inaparente, pois é aí que reside a sua substância. Assim, na arte, como em qualquer manifestação cultural, por mais secular que aparente ser, se expressa sempre uma preocupação última. Para Heidegger, a arte é fonte de revelação da verdade. Todavia, essa revelação traz em si o ocultamento da mesma verdade, posto que a verdade e a não-verdade acontecem simultaneamente na obra de arte. Portanto, à luz dos estudos feitos por esses dois autores, tentamos captar o desnudar de Menino morto .(AU)

ANÁLISE DAS MUDANÇAS DOS FATORES DETERMINANTES DA ESTRUTURA DE CAPITAL EM FUNÇÃO DO CICLO DE VIDA DAS EMPRESAS BRASILEIRAS

As várias teorias acerca da estrutura de capital despertam interesse motivando diversos estudos sobre o assunto sem, no entanto, ter um consenso. Outro tema aparentemente pouco explorado refere-se ao ciclo de vida das empresas e como ele pode influenciar a estrutura de capital. Este estudo teve como objetivo verificar quais determinantes possuem maior relevância no endividamento das empresas e se estes determinantes alteram-se dependendo do ciclo de vida da empresa apoiada pelas teorias Trade Off, Pecking Order e Teoria da Agência. Para alcançar o objetivo deste trabalho foi utilizado análise em painel de efeito fixo sendo a amostra composta por empresas brasileiras de capital aberto, com dados secundários disponíveis na Economática® no período de 2005 a 2013, utilizando-se os setores da BM&FBOVESPA. Como resultado principal destaca-se o mesmo comportamento entre a amostra geral, alto e baixo crescimento pelo endividamento contábil para o determinante Lucratividade apresentando uma relação negativa, e para os determinantes Oportunidade de Crescimento e Tamanho, estes com uma relação positiva. Para os grupos de alto e baixo crescimento alguns determinantes apresentaram resultados diferentes, como a singularidade que resultou significância nestes dois grupos, sendo positiva no baixo crescimento e negativa no alto crescimento, para o valor colateral dos ativos e benefício fiscal não dívida apresentaram significância apenas no grupo de baixo crescimento. Para o endividamento a valor de mercado foi observado significância para o Benefício fiscal não dívida e Singularidade. Este resultado reforça o argumento de que o ciclo de vida influência a estrutura de capital.

O BOCA A BOCA ON-LINE: AS IMPLICAÇÕES DA VOZ DO CONSUMIDOR NA COMUNICAÇÃO DE MERCADO

O consumidor contemporâneo, inserido em um novo ambiente de comunicação, potencializa suas expressões, capaz de avaliar uma marca ou produto e transmitir sua opinião pelas redes sociais, ou seja, o consumidor expressa suas opiniões e desejos dialogando com seus pares de forma espontânea nas redes sociais on-line. É neste ambiente de participação e interação (ciberespaço) que está nosso objeto de estudo, o boca a boca on-line – a voz do consumidor contemporâneo, também conhecido como uma manifestação informativa pessoal ou uma conversa, a opinion sharing. Proporcionado pelos consumidores nas redes sociais on-line, o boca a boca se fortalece em função das possibilidades de interação, característica da sociedade em rede. Nesse cenário, oobjetivo desta pesquisa é caracterizar o boca a boca on-line como um novo fluxo comunicacional entre consumidores, hoje potencializado pelas novas tecnologias da comunicação, capazes de alterar a percepção da marca e demonstrar o uso, pelas marcas, das redes sociais on-line ainda como um ambiente de comunicação unidirecional. Mediante três casos selecionados por conveniência (dois casos nacionais e um internacional), o corpus de análise de nossa pesquisa se limitou aos 5.084 comentários disponibilizados após publicação de matérias jornalísticas no Portal G1 e nas fanpages (Facebook), ambos relativos aos casos selecionados. Com a Análise de Conteúdo dos posts, identificamos e categorizamos a fala do consumidor contemporâneo, sendo assim possível comprovar que as organizações/marcas se valem da cultura do massivo, não dialogando com seus consumidores, pois utilizam as redes sociais on-line ainda de forma unidirecional, além de não darem a devida atenção ao atual fluxo onde se evidencia a opinião compartilhada dos consumidores da sociedade em rede.

Vaccination with irradiated autologous melanoma cells engineered to secrete human granulocyte–macrophage colony-stimulating factor generates potent antitumor immunity in patients with metastatic melanoma

We conducted a Phase I clinical trial investigating the biologic activity of vaccination with irradiated autologous melanoma cells engineered to secrete human granulocyte–macrophage colony-stimulating factor in patients with metastatic melanoma. Immunization sites were intensely infiltrated with T lymphocytes, dendritic cells, macrophages, and eosinophils in all 21 evaluable patients. Although metastatic lesions resected before vaccination were minimally infiltrated with cells of the immune system in all patients, metastatic lesions resected after vaccination were densely infiltrated with T lymphocytes and plasma cells and showed extensive tumor destruction (at least 80%), fibrosis, and edema in 11 of 16 patients examined. Antimelanoma cytotoxic T cell and antibody responses were associated with tumor destruction. These results demonstrate that vaccination with irradiated autologous melanoma cells engineered to secrete granulocyte–macrophage colony-stimulating factor stimulates potent antitumor immunity in humans with metastatic melanoma.

Decrease in Phosphoribulokinase Activity by Antisense RNA in Transgenic Tobacco. Relationship between Photosynthesis, Growth, and Allocation at Different Nitrogen Levels1

To study the direct effects of photosynthesis on allocation of biomass by altering photosynthesis without altering leaf N or nitrate content, phosphoribulokinase (PRK) activity was decreased in transgenic tobacco (Nicotiana tabacum L.) with an inverted tobacco PRK cDNA and plants were grown at different N levels (0.4 and 5 mm NH4NO3). The activation state of PRK increased as the amount of enzyme was decreased genetically at both levels of N. At high N a 94% decrease in PRK activity had only a small effect (20%) on photosynthesis and growth. At low N a 94% decrease in PRK activity had a greater effect on leaf photosynthesis (decreased by up to 50%) and whole-plant photosynthesis (decreased by up to 35%) than at high N. These plants were up to 35% smaller than plants with higher PRK activities because they had less structural dry matter and less starch, which was decreased by 3- to 4-fold, but still accumulated to 24% to 31% of dry weight; young leaves contained more starch than older leaves in older plants. Leaves had a higher ion and water content, and specific leaf area was higher, but allocation between shoot and root was unaltered. In conclusion, low N in addition to a 94% decrease in PRK by antisense reduces the activity of PRK sufficient to diminish photosynthesis, which limits biomass production under conditions normally considered sink limited.

Estimating the Excess Investment in Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase in Leaves of Spring Wheat Grown under Elevated CO21

Wheat (Triticum aestivum L.) was grown under CO2 partial pressures of 36 and 70 Pa with two N-application regimes. Responses of photosynthesis to varying CO2 partial pressure were fitted to estimate the maximal carboxylation rate and the nonphotorespiratory respiration rate in flag and preceding leaves. The maximal carboxylation rate was proportional to ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) content, and the light-saturated photosynthetic rate at 70 Pa CO2 was proportional to the thylakoid ATP-synthase content. Potential photosynthetic rates at 70 Pa CO2 were calculated and compared with the observed values to estimate excess investment in Rubisco. The excess was greater in leaves grown with high N application than in those grown with low N application and declined as the leaves senesced. The fraction of Rubisco that was estimated to be in excess was strongly dependent on leaf N content, increasing from approximately 5% in leaves with 1 g N m−2 to approximately 40% in leaves with 2 g N m−2. Growth at elevated CO2 usually decreased the excess somewhat but only as a consequence of a general reduction in leaf N, since relationships between the amount of components and N content were unaffected by CO2. We conclude that there is scope for improving the N-use efficiency of C3 crop species under elevated CO2 conditions.

Three Dichotomies in Lawyers’ Ethics (With Particular Attention to the Corporation as Client)

Three usually unexpressed, and too often unnoticed, conceptual dichotomies underlie our perception and understanding of lawyers’ ethics. First, the existence of a special body of professional ethics and professional regulation presupposes some special need or risk. Criminal and civil law are apparently insufficient. Ordinary day-to-day morality and ordinary ethics, likewise, are not considered to be enough. What is the risk entailed by the notion of a profession that is special; who needs protection, and from what? Two quite different possible answers to this question provide the first of the three dichotomies examined in this article: one can understand the risk as primarily to a vulnerable client from a powerful professional; or, to the contrary, from a powerful client-lawyer combination toward vulnerable others. Second, what is the foundational orientation of lawyers? Are lawyers serving primarily their particular clients, and those clients’ preferences, choices and autonomy? Or is the primary allegiance of lawyers to some community or collective goal or interest distinct from the particular goals or interests of the client? The third dichotomy concerns not the substance of the risk, or the primary orientation, but the appropriate means of responding to that risk or that fundamental obligation. Should professional ethics be implemented primarily through rules? Or, should we rely on character and the discretion of lawyers to make a thought out, all things considered, decision? Each of these three presents a fundamental difference in how we perceive and address issues of lawyers’ ethics. Each affects our understanding and analysis on multiple levels, from (1) determining the appropriate or requisite conduct in a particular situation, to (2) framing a specific rule or approach for a particular category of situations, to (3) more general or abstract theory or policy. A person’s inclinations in regard to the dichotomies affects the conclusions that person will reach on each of those levels of analysis, yet those inclinations and assumptions are frequently unexamined and unarticulated. One’s position on each of the dichotomies tends to structure the approach and outcome without the issues and choice having been explicitly addressed or possibly even noticed. This article is an effort to ameliorate that problem. Part I addresses the question of what is the risk in the work of lawyers, or the function of lawyers, for which professional ethics is the answer. The concluding section focuses on the particular problem of the corporation as client. Part II then asks the related and possibly consequent question of what is the foundational orientation or allegiance of the lawyer? Is it to the individual client? Or is it to some larger community interest? Again, the concluding section focuses on the corporation. Part III turns to the means or method for addressing the obligations and possible problems of the professional ethics of lawyers. Should lawyers’ ethics guide and confine the conduct of lawyers primarily through rules? Or should it function primarily through reliance on the knowledge, judgment and character of lawyers? If the latter were the guide, ethical decisions would be made on a situation by situation basis under the discretion of each lawyer. Toward the end of each discussion possibilities for bridging the dichotomy are considered (and with such bridges each dichotomy may come to look more like a spectrum or continuum.). At several points after its introduction in Parts I and II, the special problem of the corporation as client is revisited and possible solutions suggested. Illustrating the usefulness of keeping the dichotomies in view, Part IV applies them to several exemplary situations of ethical difficulty in actual lawyer practice. For readers finding it difficult to envision the consequences of these distinctions, turning ahead to Part IV may be useful in making the discussion more concrete. Some commonalities across the dichotomies and connections among them are then developed in the concluding section, Part V.

“Fall” and Redemption in the Thought of Martin Heidegger and Jacques Lacan

This dissertation examines and develops Martin Heidegger’s concept of “falling” as a significant historical-philosophical principle. Falling, however, is primarily understood as a concept of the early Heidegger, whereas I argue that Heidegger continues to rely upon it, both explicitly and implicitly, throughout his career. Falling is a description ofphilosophical and Western history, known as metaphysics, and the description of man’s relationship to Being. Thus, falling relates to the most significant streams in Heidegger’s later thought, too, including the truth of Being, the death of God, the gods, the overcoming of metaphysics, and meditative thinking. I then reinterpret the traditional theology of the Fall narrative from Genesis in light of falling as philosophical concept, extending Heidegger’s own “destruction” of Western metaphysics in relation to one of its grounding myths. I move on to demonstrate the significance of a falling understanding in a rereading of the death of God and the end of metaphysics by examining Heidegger’s engagement with Nietzsche. I conclude by incorporating Jacques Lacan’s psychoanalysis as a further extension of Heidegger’s discourse on falling, showing that the subject’s discourse and relationship to the truth of Being is at the core of his constitution and neurosis.
