Reflexões sobre a formação do acervo da Academia de Direito do Largo de São Francisco: do século XIX aos nossos dias

O trabalho apresenta algumas reflexões sobre a história da formação do acervo acadêmico dos cursos jurídicos do Brasil criados no século XIX, especificamente da Faculdade de Direito da Universidade de São Paulo. A primeira Biblioteca Pública de São Paulo, fundada em 1825, exerceu forte influência para que o Convento dos frades franciscanos recebesse a escola de direito criada por Decreto Imperial, em razão de seu fundo bibliográfico de 5.000 mil livros, preponderantemente de cunho eclesiástico, e considerável para os padrões culturais do Brasil à época. Atualmente configura-se como uma importante biblioteca jurídica acadêmica da América Latina e, ao longo da sua história tem sido uma instituição de depósito moral, isto é, recebe doações das mais diversas localidades do país, encaminhadas espontaneamente pelos autores para ter sua obra disponibilizada no acervo do primeiro e um dos mais tradicionais cursos de Direito do Brasil. Atualmente, este acervo está estimado em aproximadamente 400 mil itens, com doações de personalidades brasileiras. Outro ponto estudado refere-se ao estabelecimento de critérios para seleção de material – corpo editorial, autores de renome, relevância nos temas abordados etc. – em razão do boom editorial ocorrido na década de 1990, concomitante com o aumento de escolas de Direito no país. Chama-se à reflexão de quem atua na seara jurídica para atentar a pontos relevantes no momento da seleção para não incorrer no erro de avaliar com preconceito, modernidade, ideológico, interesse de estudo pessoal ou embasado apenas na data de publicação da obra. As ciências humanas, diferentemente de outras áreas, têm sua obsolescência mais lenta ou inexistente, decorrendo em grave erro para o Direito julgar exclusivamente pela data de publicação, o que torna premente aos profissionais bibliotecários dominarem conceitos básicos na área de atuação para que as bibliotecas sejam depositárias de material bibliográfico de qualidade.

Bestandsaufnahme und Kritik der Versuche zur Integration der Völkerkunde/Ethnologie in den Schulunterricht /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 68

Diese Arbeit ist der Versuch einer Bestandsaufnahme der Diskussion um die Rolle des Fachs Eth¬nologie in den allgemeinbildenden Schulen. Eine solche Übersicht zu den im deutschsprachigen Raum veröffentlichten Beiträgen lag bis dahin noch nicht vor. Sie reicht zurück bis zum Ende des 19. Jahrhunderts. Im vorliegenden Papier wurden die grundlegenden Argumentationen dargelegt, mit denen Fachvertreter und -vertreterinnen ein völkerkundliches/ethnologisches Engagement in den Schulen, in Schulbüchern und bei der Lehrerausbildung forderten. Mit einem historisch vertieften Vergleich dieser Argumentationen wurde angestrebt, Kontinuitäten und Brüche in der Diskussion darzustellen. Diese Perspektive ermöglichte zum einen die Darstel¬lung von älteren und kaum mehr rezipierten Beiträgen in einem größeren Rahmen, zum anderen jedoch auch eine Kritik der vorliegenden, oft nur vordergründig verschiedenen Ansätze. Im Schlusskapitel stellte der Autor essentialistische/relativistische und universalistische Ansätze gegenüber und formulierte darauf basierend Ausgangspunkte eines weiteren schulischen Engagements im Rahmen einer vergleichenden Sozialwissenschaft Ethnologie. Im Anhang der Arbeit befindet sich eine chronologische Biblioghraphie all jener Beiträge, die Ethnologen und Ethnologinnen zur Integration ihres Fachs in die Schulen verfassten.

Environmental influence on the phenotype: Morphological variation in human dentition

This work is about the role that environment plays in the production of evolutionary significant variations. It starts with an historical introduction about the concept of variation and the role of environment in its production. Then, I show how a lack of attention to these topics may lead to serious mistakes in data interpretation. A statistical re-analysis of published data on the effects of malnutrition on dental eruption, shows that what has been interpreted as an increase in the mean value, is actually linked to increase of variability. In Chapter 3 I present the topic of development as a link between variability and environmental influence, giving a review of the possible mechanisms by which development influences evolutionary dynamics. Chapter 4 is the core chapter of the thesis; I investigated the role of environment in the development of dental morphology. I used dental hypoplasia as a marker of stress, characterizing two groups. Comparing the morphology of upper molars in the two groups, three major results came out: (i) there is a significant effect of environmental stressors on the overall morphology of upper molars; (ii) the developmental response increases morphological variability of the stressed population; (iii) increase of variability is directional: stressed individuals have increased cusps dimensions and number. I also hypothesized the molecular mechanisms that could be responsible of the observed effects. In Chapter 5, I present future perspectives for developing this research. The direction of dental development response is the same direction of the trend in mammalian dental evolution. Since malnutrition triggers the developmental response, and this particular kind of stressor must have been very common in our class evolutionary history, I propose the possibility that environmental stress actively influenced mammals evolution. Moreover, I discuss the possibility of reconsidering the role of natural selection in the evolution of dental morphology.

Einfluss der Einzeldosisblisterverpackung von festen Oralia auf die Arzneimitteltherapiesicherheit, Information und Zufriedenheit stationär behandelter Patienten in einer prospektiven, multizentrischen Studie

Bei der vorliegenden Studie wurde die Machbarkeit und Qualität der Arzneimittelverteilung von oralen Arzneimitteln in Einzeldosisblisterverpackungen je abgeteilte Arzneiform (EVA) untersucht.rnDie Studie wurde als offene, vergleichende, prospektive und multizentrische Patientenstudie durchgeführt. Als Studienmedikation standen Diovan®, CoDiovan® und Amlodipin in der EVA-Verpackung zur Verfügung. Die Verteilfehlerrate in der EVA- und Kontroll-Gruppe stellte den primären Zielparameter dar. Das Patientenwissen, die Patientenzufriedenheit und die Praktikabilität des EVA-Systems, sowie die Zufriedenheit der Pflegekräfte wurden mithilfe von Fragebogen evaluiert. Insgesamt wurden 2070 gültige Tablettenvergaben bei 332 Patienten in sechs verschiedenen Krankenhäusern geprüft. Es wurde in der EVA-Gruppe ein Verteilungsfehler von 1,8% und in der Kontroll-Gruppe von 0,7% ermittelt. Bei den Patienten-Fragebogen konnten insgesamt 292 Fragebogen ausgewertet werden. Die Ergebnisse zeigten einen ungenügenden Informationsstand der Patienten über ihre aktuellen, oralen Arzneimittel. In den 80 ausgefüllten Pflegekräfte-Fragebogen gaben über 80% an, dass Fehler beim Richten durch das EVA-System besser erkannt werden können. rnZusammenfassend kann gesagt werden, dass die erhöhte Fehlerrate in der EVA-Gruppe im Vergleich zur Kontroll-Gruppe durch mehrere Störfaktoren bedingt wurde. Grundsätzlich konnte eine sehr positive Resonanz auf das EVA-System bei den Patienten und den Pflegekräften beobachtet werden. rn

Recovery and Analysis of Transaction Scope from Scattered Information in Java Enterprise Applications

Java Enterprise Applications (JEAs) are large systems that integrate multiple technologies and programming languages. Transactions in JEAs simplify the development of code that deals with failure recovery and multi-user coordination by guaranteeing atomicity of sets of operations. The heterogeneous nature of JEAs, however, can obfuscate conceptual errors in the application code, and in particular can hide incorrect declarations of transaction scope. In this paper we present a technique to expose and analyze the application transaction scope in JEAs by merging and analyzing information from multiple sources. We also present several novel visualizations that aid in the analysis of transaction scope by highlighting anomalies in the specification of transactions and violations of architectural constraints. We have validated our approach on two versions of a large commercial case study.

A Sociological Study of the Political Subsystem in Yugoslavia

In this critical analysis of sociological studies of the political subsystem in Yugoslavia since the fall of communism Mr. Ilic examined the work of the majority of leading researchers of politics in the country between 1990 and 1996. Where the question of continuity was important, he also looked at previous research by the writers in question. His aim was to demonstrate the overall extent of existing research and at the same time to identify its limits and the social conditions which defined it. Particular areas examined included the problems of defining basic concepts and selecting the theoretically most relevant indicators; the sources of data including the types of authentic materials exploited; problems of research work (contacts, field control, etc.); problems of analysisl and finally the problems arising from different relations with the people who commission the research. In the first stage of the research, looking at methods of defining key terms, special attention was paid to the analysis of the most frequently used terms such as democracy, totalitarianism, the political left and right, and populism. Numerous weaknesses were noted in the analytic application of these terms. In studies of the possibilities of creating a democratic political system in Serbia and its possible forms (democracy of the majority or consensual democracy), the profound social division of Serbian society was neglected. The left-right distinction tends to be identified with the government-opposition relation, in the way of practical politics. The idea of populism was used to pass responsibility for the policy of war from the manipulator to the manipulated, while the concept of totalitarianism is used in a rather old-fashioned way, with echoes of the cold war. In general, the terminology used in the majority of recent research on the political subsystem in Yugoslavia is characterised by a special ideological style and by practical political material, rather than by developed theoretical effort. The second section of analysis considered the wider theoretical background of the research and focused on studies of the processes of transformation and transition in Yugoslav society, particularly the work of Mladen Lazic and Silvano Bolcic, who he sees as representing the most important and influential contemporary Yugoslav sociologists. Here Mr. Ilic showed that the meaning of empirical data is closely connected with the stratification schemes towards which they are oriented, so that the same data can have different meanings in shown through different schemes. He went on to show the observed theoretical frames in the context of wider ideological understanding of the authors' ideas and research. Here the emphasis was on the formalistic character of such notions as command economy and command work which were used in analysing the functioning and the collapse of communist society, although Mr. Ilic passed favourable judgement on the Lazic's critique of political over-determination in its various attempts to explain the disintegration of the communist political (sub)system. The next stage of the analysis was devoted to the problem of empirical identification of the observed phenomena. Here again the notions of the political left and right were of key importance. He sees two specific problems in using these notion in talking about Yugoslavia, the first being that the process of transition in the FR Yugoslavia has hardly begun. The communist government has in effect remained in power continuously since 1945, despite the introduction of a multi-party system in 1990. The process of privatisation of public property was interrupted at a very early stage and the results of this are evident on the structural level in the continuous weakening of the social status of the middle class and on the political level because the social structure and dominant form of property direct the majority of votes towards to communists in power. This has been combined with strong chauvinist confusion associated with the wars in Croatia and Bosnia, and these ideas were incorporated by all the relevant Yugoslav political parties, making it more difficult to differentiate between them empirically. In this context he quotes the situation of the stream of political scientists who emerged in the Faculty of Political Science in Belgrade. During the time of the one-party regime, this faculty functioned as ideological support for official communist policy and its teachers were unable to develop views which differed from the official line, but rather treated all contrasting ideas in the same way, neglecting their differences. Following the introduction of a multi-party system, these authors changed their idea of a public enemy, but still retained an undifferentiated and theoretically undeveloped approach to the issue of the identification of political ideas. The fourth section of the work looked at problems of explanation in studying the political subsystem and the attempts at an adequate causal explanation of the triumph of Slobodan Milosevic's communists at four subsequent elections was identified as the key methodological problem. The main problem Mr. Ilic isolated here was the neglect of structural factors in explaining the voters' choice. He then went on to look at the way empirical evidence is collected and studied, pointing out many mistakes in planning and determining the samples used in surveys as well as in the scientifically incorrect use of results. He found these weaknesses particularly noticeable in the works of representatives of the so-called nationalistic orientation in Yugoslav sociology of politics, and he pointed out the practical political abuses which these methodological weaknesses made possible. He also identified similar types of mistakes in research by Serbian political parties made on the basis of party documentation and using methods of content analysis. He found various none-sided applications of survey data and looked at attempts to apply other sources of data (statistics, official party documents, various research results). Mr. Ilic concluded that there are two main sets of characteristics in modern Yugoslav sociological studies of political subsystems. There are a considerable number of surveys with ambitious aspirations to explain political phenomena, but at the same time there is a clear lack of a developed sociological theory of political (sub)systems. He feels that, in the absence of such theory, most researcher are over-ready to accept the theoretical solutions found for interpretation of political phenomena in other countries. He sees a need for a stronger methodological bases for future research, either 1) in complementary usage of different sources and ways of collecting data, or 2) in including more of a historical dimension in different attempts to explain the political subsystem in Yugoslavia.

Language Construction of Reality in the German Tabloid Press/on Materials of BILD Newspaper/

From the moment of their birth, a person's life is determined by their sex. Goroshko wanted to find out why this difference is so striking, why society is so determined to sustain it, and how it can persist even when certain national or behavioural stereotypes are erased. She believes there are both social and biological differences between men and women, and set out to analyse these distinctions as they are manifested in language. Certain general characteristics can be identified. Males tend to write with less fluency, to refer to events in a verb phrase, to be time-oriented, to involve themselves more in their references to events, to locate events in their personal sphere of activity, and to refer less to others. Goroshko therefore concludes that the male is more active, more ego-involved in what he does and less concerned about others. Women were more fluent, referred to events in a noun-phrase, were less time-oriented, tended to be less involved in their event references, located events within their interactive community, and referred more to others. They spent much more time discussing personal and domestic subjects, relationship problems, family, health and reproductive matters, weight, food and clothing, men, and other women. Computer analysis showed that female speech was substantially more emotional, using hyperbole, metaphor, comparisons, epithets, ways of enumeration, interjections, rhetorical questions and exclamations. The level of literacy was higher in female speech, and women made fewer grammatical and spelling mistakes in written texts. Goroshko believes that her findings have relevance beyond the linguistic field. When working on anonymous texts she has been able to decide on the sex of the author and so believes that her research may even be of benefit to forensic science.

Ex vivo assessment of chemotherapy-induced apoptosis and associated molecular changes in patient tumor samples

BACKGROUND: There are inherent conceptual problems in investigating the pharmacodynamics of cancer drugs in vivo. One of the few possible approaches is serial biopsies in patients. However, this type of research is severely limited by methodological and ethical constraints. MATERIALS AND METHODS: A modified 3-dimensional tissue culture technique was used to culture human tumor samples, which had been collected during routine cancer operations. Twenty tumor samples of patients with non-small cell lung cancer (NSCLC) were cultured ex vivo for 120 h and treated with mitomycin C, taxotere and cisplatin. The cytotoxic activity of the anticancer agents was quantified by assessing the metabolic activity of treated tumor cultures and various assays of apoptosis and gene expression were performed. RESULTS: The proliferative activity of the tissue was maintained in culture as assessed by Ki-67 staining. Mitomycin C, cisplatin and taxotere reduced the metabolic activity of the tumor tissue cultures by 51%, 29% and 20%, respectively, at 120 h. The decrease in metabolic activity corresponded to the induction of apoptosis as demonstrated by the typical morphological changes, such as chromatin condensation and nuclear fragmentation. In addition, activated caspase-3 could be verified in apoptotic cells by immunohistochemistry. To verify functional aspects of apoptosis, the induction of chemotherapy-induced cell death was inhibited with the caspase inhibitor z-VAD.fmk. RNA was extracted from the tissue cultures after 120 h of ex vivo drug treatment and was of sufficient quality to allow quantitative PCR. CONCLUSION: The 3-dimensional ex vivo culture technique is a useful method to assess the molecular effects of pharmacological interventions in human cancer samples in vitro. This culture technique could become an important tool for drug development and for the prediction of in vivo drug efficacy.

Patterns of regional brain hypometabolism associated with knowledge of semantic features and categories in Alzheimer's disease

The study of semantic memory in patients with Alzheimer's disease (AD) has raised important questions about the representation of conceptual knowledge in the human brain. It is still unknown whether semantic memory impairments are caused by localized damage to specialized regions or by diffuse damage to distributed representations within nonspecialized brain areas. To our knowledge, there have been no direct correlations of neuroimaging of in vivo brain function in AD with performance on tasks differentially addressing visual and functional knowledge of living and nonliving concepts. We used a semantic verification task and resting 18-fluorodeoxyglucose positron emission tomography in a group of mild to moderate AD patients to investigate this issue. The four task conditions required semantic knowledge of (1) visual, (2) functional properties of living objects, and (3) visual or (4) functional properties of nonliving objects. Visual property verification of living objects was significantly correlated with left posterior fusiform gyrus metabolism (Brodmann's area [BA] 37/19). Effects of visual and functional property verification for non-living objects largely overlapped in the left anterior temporal (BA 38/20) and bilateral premotor areas (BA 6), with the visual condition extending more into left lateral precentral areas. There were no associations with functional property verification for living concepts. Our results provide strong support for anatomically separable representations of living and nonliving concepts, as well as visual feature knowledge of living objects, and against distributed accounts of semantic memory that view visual and functional features of living and nonliving objects as distributed across a common set of brain areas.

Conceptual and Theoretical Frameworks for Organised Violence

The possibility of violence is ubiquitous in human social relations, its forms are manifold and its causes complex. Different types of violence are interrelated but in complex ways, and they are studied within a wide range of disciplines, so that a general theory, while possible, is difficult to achieve. This paper acknowledges that violence can negate power and that all forms of social power can entail violence, proceeds on the assumption that the organisation of violence is a particular source of social power. It therefore explores the general relationships of violence to power, the significance of war as the archetype of organised violence, the relationships of other types (revolution, terrorism, genocide) to war, and the significance of civilian-combatant stratification for the understanding of all types of organised violence. It then discusses the problems of applying conceptual types in analysis, and the necessity of a historical framework for theorising violence. The paper concludes by offering such a framework in the transition from industrialised total war to global surveillance war.
