Leitura de Perto do Coração Selvagem à luz da teoria existencialista de Jean Paul Sartre
No full textEste trabalho consiste no estudo da obra Perto do coração selvagem, de Clarice Lispector, à luz de conceitos da teoria existencialista de Jean Paul Sartre. Para realizar a análise, inicialmente, propõe-se o estudo de aspectos bibliográficos sobre Clarice Lispector, que se destaca na literatura brasileira por seu estilo singular de composição, priorizando dar destaque às sensações dos protagonistas em detrimento de enredos lineares, além de adotar uma temática de cunho introspectivo e existencialista. Depois pretende-se empreender uma análise de sua obra como um todo, bem como do livro Perto do coração selvagem, especificamente. Na sequência, apresenta-se comentários críticos sobre o livro de Lispector, e descreve-se de forma breve a evolução histórica da teoria existencialista a partir de Franz Brentano, passando por Husserl e Heidegger até culminar em Sartre com sua obra magna O ser e o nada. Por fim, propõe-se a estabelecer a aproximação entre a teoria existencialista de Sartre com as propostas da obra de Clarice Lispector.This research studies Clarice Lispector’s work of literature Perto do coração selvagem, pursuant to Jean Paul Sartre’s existentialist theory. In order to undertake the assessment, initially, we suggest the study of Clarice Lispector’s bibliography, which we deem distinctive within Brazilian Literature for her original style that prioritizes leading characters feelings rather than linear plots and also adopts an introspective and existentialist facet. After we assessed her literary works as a whole, specially the book Perto do coração selvagem. Following we present critical comments over the books of the author and we present a brief description of the existentialist theory historical evolution based on Fraz Brentano, Husserl, Heidegger up to Jean Paul Sartre and his most important work “O ser e o nada”. Finally, we propose to establish a convergence between existentialistic theory from Sartre to Lispector’s first novel ideas
In vitro quality of platelets during prolonged storage after washing with three platelet additive solutions
No full textBackground and Objectives Patients with anaphylactic transfusion reactions require washed platelet concentrates (PCs) for subsequent platelet (PLT) transfusions. New PLT additive solutions (PASs) contain substances that might be beneficial for the preservation of PLT function during storage. This study compares the quality of PLTs washed and stored with T-Sol, Composol or SSP+. Study Design and Methods Fifteen buffy coats were pooled and divided into three parts. PCs with 30% plasma and 70% PAS (T-Sol, Composol or SSP+) were prepared. Washing was performed on day 5 of storage. Ten PCs were prepared and washed with each PAS. In vitro variables including haemostatic function (clotting time and clot retraction) were analysed on day 5 before, directly after and up to 2days after washing. Results Swirling was well preserved, and pH was within acceptable limits (6·4-7·4) during storage for all PASs. The PLT number was reduced by washing for all PASs, and T-Sol PCs had a further decrease during storage. PLTs in T-Sol were spontaneously more activated and had lower capacity to respond to an agonist than Composol or SSP+ PLTs. The haemostatic function was only slightly changed by washing and during postwashing storage. Conclusion PLTs washed with T-Sol, Composol or SSP+ had good in vitro quality for two days after washing despite absence of glucose. PLTs in T-Sol were more affected by the washing procedure and subsequent storage than Composol or SSP+ PLTs as judged by higher spontaneous activation. © 2011 The Author(s).

Ice and the origin of life
No full textMannigfaltige Umgebungen wurden bisher als Ort für die Entstehung des Lebens vorgeschlagen. Ausgehend von den Ergebnissen in der Arktis durchgeführter Experimente eines der Autoren sowie weiteren Hinweisen zu besonderen Eigenschaften des arktischen Meereis in der Literatur, schlagen wir vor, dass eine für den Ursprung des Lebens bislang weitgehend unbeachtete Umgebung, nämlich das Meerwassereis der Polkappen, ausgezeichnete Bedingungen für die Entwicklung der allerfrühesten genetischen Elemente geboten haben muss. Meereis kann Substanzen durch Ausfrieren des Wassers beträchtlich aufkonzentrieren; die entstehenden flüssigkeitsgefüllten Kaviolen fördern durch die tiefe Temperatur und die hohe Ionenstärke der Salzlösung besonders stabile intra- und intermolekulare Wasserstoffbrücken. Dies ist wichtig bei Reaktionen von RNA-Molekülen, denen eine Schlüsselrolle in einer ersten Chemie des Lebens zugeschrieben wird. Speziell für die Entwicklung eines RNA-Replikationssystems sowie eine "RNA-Welt" bietet Meereis offenbar ideale Voraussetzungen. Meereis scheint aber auch in der Sortierung, der Katalyse und für die Begünstigung synthetischer Prozessen viele, noch weitgehend unerforschte, Fähigkeiten zu haben. Dieser Artikel sammelt und präsentiert das Wissen um Meereis, gesehen aus unserer speziellen Sicht und soll Forscher unterschiedlicher Fachrichtungen anregen, Meereissysteme in ihre Überlegungen und experimentellen Untersuchungen zur Ergründung des Lebensursprunges einzubeziehen.Many different locations on the primitive earth have been proposed as possible places for the origin of life. Experimental investigations of sea ice, in particular the studies of one author in the arctis and findings in the literature, incited us to propose sea ice as a matrix suitable for the evolution of living systems. This heterophasic environment, hitherto disregarded by theories dealing with the origin of life, offers in our opinion excellent conditions for the development of primitive genetic elements. Sea ice can concentrate substances considerably. The intramolecular and intermolecular base-pairing of RNA strands, reactions that are widely accepted to be crucial for the evolution of living systems, are stabilized by the low temperature and the high ionic strength of the brine formed in the liquid channels. Sea ice conditions seem to be ideal for the development of an RNA replication system and and an "RNA World". In addition, sea ice offers still widely unexplored possibilities in sorting and specific catalysis which seem to be favourable for prebiotic reactions in general. This paper presents the available informations about the sea ice environment. It wants to encourage scientists of different fields to take sea ice into consideration for theoretical and experimental studies of the origin of life
The sociological perspective on the knowledge-based society: assumptions, facts and visions
No full textThe paper will present the central discourse of the knowledge-based society. Already in the 1960s the debate of the industrial society already raised the question whether there can be considered a paradigm shift towards a knowledge-based society. Some prominent authors already foreseen ‘knowledge’ as the main indicator in order to displace ‘labour’ and ‘capital’ as the main driving forces of the capitalistic development. Today on the political level and also in many scientific disciplines the assumption that we are already living in a knowledge-based society seems obvious. Although we still do not have a theory of the knowledge-based society and there still exist a methodological gap about the empirical indicators, the vision of a knowledge-based society determines at least the perception of the Western societies. In a first step the author will pinpoint the assumptions about the knowledge-based society on three levels: on the societal, on the organisational and on the individual level. These assumptions are relied on the following topics: a) The role of the information and communication technologies; b) The dynamic development of globalisation as an ‘evolutionary’ process; c) The increasing importance of knowledge management within organisations; d) The changing role of the state within the economic processes. Not only the differentiation between the levels but also the revision of the assumptions of a knowledge-based society will show that the ‘topics raised in the debates’ cannot be considered as the results of a profound societal paradigm shift. However what seems very impressive is the normative and virtual shift towards a concept of modernity, which strongly focuses on the role of technology as a driving force as well as on the global economic markets, which has to be accepted. Therefore – according to the official debate - the successful adaptation of these processes seems the only way to meet the knowledge-based society. Analysing the societal changes on the three levels, the label ‘knowledge-based society’ can be seen critically. Therefore the main question of Theodor W. Adorno during the 16th Congress of Sociology in 1968 did not loose its actuality. Facing the societal changes he asked whether we are still living in the industrial society or already in a post-industrial state. Thinking about the knowledge-based society according to these two options, this exercise would enrich the whole debate in terms of social inequality, political, economic exclusion processes and at least the power relationship between social groups.knowledge-based society; ICT; knowledge management; technology

Career building for women postgraduate and early career researchers in law schools in Germany
No full textWhen compared with the United Kingdom, for example, Germany has a distinct academic system and career structure. The time period between finishing a PhD and obtaining a professorship is, in most instances, limited to a maximum of six years. Women in Germany leave legal academia in disproportionate numbers, either during postgraduate research or soon after. The Minerva LAW (Legal and Academic Women’s) Network was founded inter alia to support postgraduate and early career women researchers. It gives this group access to leading women in legal academia, the legal profession and beyond, as well as information on career building. It provides guidance on how to improve employability and long-term career prospects. In this regard, this chapter examines the efforts undertaken by the Minerva LAW Network in order to facilitate the career progression of women postgraduates and early career researchers in law schools in Germany
