Ruptura e Legado: o colapso da cordialidade oficial entre o Brasil e a Argentina

Este trabalho busca identificar os fatores que concorrem para explicar a mudança no eixo entre a Argentina e o Brasil, no começo da década de 1980, quando as duas diplomacias convergiram em um projeto de integração inovador. O argumento apresentado defende que a aproximação entre os dois países foi o legado, inesperado, do relacionamento bilateral ao longo da gestão do Presidente Geisel (1974-1979).

Government policy and private investment in Brazil (1955/82)

The questlon of the crowding-out of private !nvestment by public expenditure, public investment in particular , ln the Brazilian economy has been discussed more in ideological terrns than on empirical grounds. The present paper tries to avoid the limitation of previous studies by estlmatlng an equation for private investment whlch makes it possible to evaluate the effect of economic policies on prlvate investment. The private lnvestment equation was deduced modifylng the optimal flexible accelerator medel (OFAM) incorporating some channels through which public expendlture influences privateinvestment. The OFAM consists in adding adjustment costs to the neoclassical theory of investrnent. The investment fuction deduced is quite general and has the following explanatory variables: relative prices (user cost of capitaljimput prices ratios), real interest rates, real product, public expenditures and lagged private stock of capital. The model was estimated for private manufacturing industry data. The procedure adopted in estimating the model was to begin with a model as general as possible and apply restrictions to the model ' s parameters and test their statistical significance. A complete diagnostic testing was also made in order to test the stability of estirnated equations. This procedure avoids ' the shortcomings of estimating a model with a apriori restrictions on its parameters , which may lead to model misspecification. The main findings of the present study were: the increase in public expenditure, at least in the long run, has in general a positive expectation effect on private investment greater than its crowding-out effect on priva te investment owing to the simultaneous rise in interst rates; a change in economlc policy, such as that one of Geisel administration, may have an important effect on private lnvestment; and reI ative prices are relevant in determining the leveI of desired stock of capital and private investrnent.

A politica de controle do governo em relação as universidades federais autarquicas e suas consequencias sobre as estruturas administrativas destas instituições

Esta monografia se situa no campo do relacionamento Governo Federal-universidades por ele mantidas. concebido basicamente como um problema político.e onde se projetam relações sociais mais amplas. Detem-se. contudo. sobre os reflexos e conseqüências de tal problema político e social que afetam as estruturas administrativas e organizacionais das universidades autárquicas. Acredita-se que o enfoque mais capaz de descrever aquele relacionamento e mais fecundo para uma mudança no comportamento organizacional da universidade seria o da análise da política de controle ou de "supervisão ministerial" (na linguagem da Reforma Administrativa de 1967) que o Governo. implicita ou explicitamente. mantém sobre as rais autárquicas. universidades fede Um panorama da evolução histórica desta política de controle. desde seus primórdios no século XVI até fins do governo Geisel (1978). destacaria - como o faz o Capítulo I - contornos adstringentes. uma política de "rédeas curtas" para com o ensino superior. a postura atributiva. o regime de burocracias públicas. a ascensao do poder normativo de orgãos-meio da cúpula federal. O erro da política de controle do Governo tem sido de natureza pedagógica: ignorar a dinâmica da -universidade e. pelo uso do poder sobre os meios. Entre as consequencias de tal política sobre as estruturas administrativas da universidade federal autárquica. alguns traços característicos, como a hipertrofia dos setores de atividades-meio, a verticalização das cadeias de informação e decisão, a multiplicação de funções de controle intermediário, poderiam mostrar empiricamente como vem a fazê-lo o Capítulo III - a predominãncia de uma certa "introversão organizacional" em vez de uma desejável "extroversão organizacional", situação de uma instituição universitária mais estrutura da em função de suas atividades substantivas e mais eficaz nas respostas às demandas do ambiente. A monografia se conclui por sugestões para uma nova política de controle, redimensionado como uma macrofunção sociaI conduzida politicamente e não autoritariamente pelo Governo, em que a universidade, aberta, esteja sempre exposta ao estímulo realimentador de forças sociais externas. e acessível à participação de forças internas no processo decisório, tornado mais autônomo, horizontal e permeável.

"Os bárbaros estão chegando": o processo de democratização do governo Richa no Paraná

O presente trabalho de pesquisa acadêmica abrange a análise da conjuntura política do processo de transição democrática no Brasil e no Paraná, ocorrida no final da década de 1970 e inícios dos anos 80. No capítulo introdutório examino os elementos teórico-metodológicos, que são as categorias de análise que utilizo no estudo da situação concreta brasileira, como contexto amplo, e da conjuntura das eleiçôes de 1982 e do governo de José Richa no Paraná. Era necessário examinar a concepçâo "ampliada" de Estado, o conceito de estrutura e de superestrutura do bloco histórico e a concepção da vertente da democracia liberal e da vertente da democracia popular, no enfoque da literatura do materialismo histórico-dialético, de autores clássicos e modernos. No segundo capítulo examino o projeto de transição democrática dos generais presidentes Geisel e Figueiredo: um plano dos militares e das elites brasileiras para salvar as elites no poder, na travessia pelo alto. O projeto não ia além da legitimação do regime e do modelo econômico pela passagem do governo militar aos civis, por um processo eleitoral duvidoso. No Paraná, objetivo principal da pesquisa, examino o projeto liberal do governo do PMDB de Richa, desde a organizaçâo partidária, a elaboraçâo das diretrizes de governo, a campanha eleitoral, a participaçâo de intelectuais de ponta na campanha, as alianças do PMDB com os setores populares da sociedade até a composição e a "direitização" do governo. "OS BÁRBAROS ESTÃO CHEGANDO", título principal da dissertação, era a denominação que a aristocracia (elite) curitibana atribuiu a José Richa, quando o mesmo ganhou as eleições ao governo do Paraná, pelo fato de ser do interior do Estado e não fazer parte do mundo civilizado da Curitiba cosmopolita. No terceiro capítulo examino a questão da democratização da escola pública do Estado pela instituição das eleições para diretor e vice-diretor da escola, pelos professores, servidores, alunos e pais de alunos. Digo que a democracia vai além do decreto governamental que estabelece as eleições. Digo ainda que o discurso na prática é outro, no caso do governo Richa e da educação. A questão básica da pesquisa é trabalhar a idéia de que a educação é um campo de disputas e confrontos de classes pela hegemonia do poder, em que a classe dominante luta para manter-se no poder como classe dirigente e as classes subalternas ora se mantém aliadas e como classes auxiliares à classe dominante, ora consentem e raras vezes rebelam-se contra a dominaçâo da classe dirigente.

O programa escola ativa e inovação pedagógica: um estudo de caso etnográfico

Esta pesquisa apresenta os resultados do estudo sobre a prática pedagógica em uma classe multisseriada do programa escola ativa. A mesma tem como objetivo identificar a existência de práticas pedagógicas inovadoras na sala de aula do referido programa. Trata-se de um estudo de caso etnográfico, de abordagem qualitativa, o qual nos possibilitou a análise da realidade concreta, por meio da análise da documentação, observação do cotidiano da sala de aula e entrevistas. As relações que ocorreram no âmbito da escola, a análise dos fatos ocorridos e do discurso dos sujeitos se constituiu de grande importância para esta pesquisa. O campo de observação da pesquisa e coleta dos dados aconteceu na Escola Municipal Ernesto Geisel na Agrovila da Barragem no município de Lagoa do Carro, em Pernambuco. Participaram deste estudo, uma classe multisseriada do programa escola ativa composta por dezessete estudantes e uma professora. As aulas aconteciam à tarde. Os alunos cursavam o 4º e 5º ano do ensino fundamental da educação básica. Utilizaram-se, como procedimentos para coleta dos dados para o registro da prática pedagógica, relatórios e anotações em diários. Por se constituir uma pesquisa de natureza qualitativa, no decorrer do trabalho de campo, foi possível e necessária à flexibilização, alterações e ajustes (no decorrer do processo), haja vista a necessidade de alcançar os objetivos pretendidos. O estudo sinalizou para a necessidade de novas reflexões sobre a inovação nas práticas pedagógicas do programa escola ativa e educação do campo, pois se concluiu que, diferentemente daquilo que é descrito nos documentos oficiais, ela não está ocorrendo na prática, sendo necessária a ruptura com o sistema arcaico e tradicional de ensino e aprendizagem.

Democracia Possível: espaços institucionais, participação social e cultura política

The present study aims at making a theoretically reflection about the reconstruction process of democracy that can be observed in the country since the opening political process, which took place with the Geisel´s government in 1974, passing through the first civil president, in 1985, the Constitution process, in 1986, and finally the Constitution promulgation in 1988. It interests to this study analyses the premise that the 1988 Constitution inaugurates the moment in which democracy starts to be reconstructed in the country, and that this reconstruction is made in such a brand new way, once it included the possibility of participation of the civil society in the deliberation of the public politics, what became possible with the creation of new spaces of a gestion shared by the three executive powers: federal; states; municipalities, and with the civil society, in the councils created in those spheres. In this way, this work wishes to focus the opening process to the civil society participation, wich became possible with the creation of the city councils of public politics. It´s about investigating the form in wich the relations set up in these hibrid spaces could be considered democratic, inclusive and promoters of effective participation, checking up tendencies, giving emphasis to regularities and some specifities encountered in the forms of participation, which have been observed in those councils. In order to comprehend the democratic process in construction in the country, the analysis of the relations established by the civil society and the local executive power in the obligatory municipal councils is taken as object of study, passing by the tensions wich evolves institutions and political practices, permeated by the local political culture. It starts from a briefly review of works already made on the subject

Ein inverses Problem für die degeneriert parabolische Richardsgleichung

In der vorliegenden Arbeit werden zwei physikalischeFließexperimente an Vliesstoffen untersucht, die dazu dienensollen, unbekannte hydraulische Parameter des Materials, wiez. B. die Diffusivitäts- oder Leitfähigkeitsfunktion, ausMeßdaten zu identifizieren. Die physikalische undmathematische Modellierung dieser Experimente führt auf einCauchy-Dirichlet-Problem mit freiem Rand für die degeneriertparabolische Richardsgleichung in derSättigungsformulierung, das sogenannte direkte Problem. Ausder Kenntnis des freien Randes dieses Problems soll dernichtlineare Diffusivitätskoeffizient derDifferentialgleichung rekonstruiert werden. Für diesesinverse Problem stellen wir einOutput-Least-Squares-Funktional auf und verwenden zu dessenMinimierung iterative Regularisierungsverfahren wie dasLevenberg-Marquardt-Verfahren und die IRGN-Methode basierendauf einer Parametrisierung des Koeffizientenraumes durchquadratische B-Splines. Für das direkte Problem beweisen wirunter anderem Existenz und Eindeutigkeit der Lösung desCauchy-Dirichlet-Problems sowie die Existenz des freienRandes. Anschließend führen wir formal die Ableitung desfreien Randes nach dem Koeffizienten, die wir für dasnumerische Rekonstruktionsverfahren benötigen, auf einlinear degeneriert parabolisches Randwertproblem zurück.Wir erläutern die numerische Umsetzung und Implementierungunseres Rekonstruktionsverfahrens und stellen abschließendRekonstruktionsergebnisse bezüglich synthetischer Daten vor.

Untersuchungen zur stereokontrollierten Synthese von 3-Mercaptolysinderivaten und Untersuchungen zur Synthese von Ansa-Seco-Steroiden

Untersuchungen zur stereokontrollierten Synthese von 3-Mercaptolysinderivaten: 3-Mercaptolysin und Peptide mit einer 3-Mercaptolysin-Einheit sind als Liganden für Nukleardiagnostika in der Kontrastmittelforschung von großem Interesse. Für das Screening Gewebe-selektiver Diagnostika sollten Mercaptolysinderivate, die sich für den Einbau in Peptide eignen, stereokontrolliert aufgebaut werden. Als Grundlage wurde im Rahmen dieser Arbeit eine sehr effiziente Synthese von Methoxymethyl-(4-oxo-butyl)-carbaminsäure-tert-butylester aus Pent-4-en-1-ol entwickelt. Nach Olefinierung des Aldehyds konnten Auxiliar-substituierte 6-Amino-hexensäure-derivate in guten Ausbeuten erhalten werden. Diese bildeten die Startmaterialien für auxiliargesteuerte Aziridinierungen mit anschließender Ringöffnung durch Schwefel-Nukleophile. Zudem wurden Azidierungen an Auxiliar-bewehrten Substraten, Michael-Additionen von Schwefel-Nukleophilen an Dehydroaminosäuren und viele weitere Reaktionen untersucht. Es galt dabei auf patentrechtlich geschützte Reaktionen zu verzichten, weil die Produkte ggf. in großem Maßstab kommerziell genutzt werden sollen. Dabei konnten alle vier stereoisomeren 2-Acetylamino-6-(tert-butoxycarbonyl-methoxymethyl-amino)-3-(4-methoxy-benzylsulfanyl)-hexansäurementhylester in guter Ausbeute synthetisiert werden. Nach Herstellung größerer Mengen der entsprechenden am Schwefelatom ungeschützten N-Fmoc-Aminosäurederivate sollen alle vier Stereoisomere in Peptide eingebaut und auf ihre Eignung als Liganden in Nukleardiagnostika untersucht werden. Untersuchungen zur Synthese neuartiger Ansa-Steroide: Über die Synthese von Ansa-Seco-Steroiden mittels eine Kaskade von intermolekularer Diels-Alder-Reaktion und anschließender Retro-Diels-Alder-Reaktion an 5,6,7,8-Tetradehydrosteroiden wurde erstmals 1986 von E. Winterfeldt et al. berichtet. Die damit eröffnete Möglichkeit eines völlig neuen Zugangs zu pharmakologisch interessanten Makrolid-Substraten konnte aber bislang nicht effektiv genutzt werden, weil insbesondere im Zusammenhang mit der Diels-Alder-Reaktion erhebliche präparative Probleme auftraten: Brauchbare Reaktivität nur bei sehr wenigen Dienophilen, Regioselektivitätsprobleme, etc. Hier galt es zu untersuchen, inwiefern sich diese Probleme durch die intramolekulare Reaktionsführung der Cycloaddition unterdrücken lassen können. Für die intramolekulare Diels-Alder-Reaktion zwischen der 5,7-Dien-Einheit des Steroids und einer an das Substrat gebundenen Dienophil-Einheit ist die Möglichkeit einer günstigen Anordnung der beiden Reaktanden-Gruppen entscheidend. Dafür wurden umfangreiche Untersuchungen zur alpha-konfigurierten Anbindung eines Dienophils in die 3-Position an 3-Hydroxy-5,6,7,8-Tetradehydrosteroiden durchgeführt: Mitsunobu-Reaktionen, Oxidations-Reduktions-Sequenzen, Oxidations-Ketalisierungs-Sequenzen, etc. Hierbei wurden zahlreiche neue Steroide synthetisiert. Es gelang jedoch nicht, 5,6,7,8-Tetradehydrosteroide mit axial in Position 3 eingebundenen Dienophilen in präparativ nutzbaren Mengen zu synthetisieren. Bei der Untersuchung intermolekularer Diels-Alder-Reaktionen zwischen Ergosterol und Brommaleinsäureanhydrid wurde vorzugsweise die Bildung der Addukte des 7,8,14,15-Tetradehydroisomers des Ergosterols beobachtet.

Das neue digitale ‚Shakespeare-Bildarchiv Oppel-Hammerschmidt‘ an der Universitätsbibliothek Mainz : Reden und Beiträge anlässlich seiner öffentlichen Vorstellung am 17. November 2008 an der Johannes Gutenberg-Universität Mainz

On the basis of illustrations of Shakespeare's Hamlet, the new digital 'Oppel-Hammerschmidt Shakespeare Illustration Archive' at the Mainz University Library - together with a lavishly-constructed and multiply-linked Web interface version - was presented to the public on 17 November 2008. This e-book, edited by Andreas Anderhub and Hildegard Hammerschmidt-Hummel, contains the speeches and presentations given on the occasion of the opening ceremony of the electronic archive. The collection of the new archive, published here for the first time, holds about 3,500 images and is part of the only Shakespeare illustration archive in the world. The Shakespeare Illustration Archive was founded in 1946 by the internationally acclaimed Shakespeare and Goethe scholar, Prof. Horst Oppel. This part of the archive was donated to the Mainz University Library on condition that its holdings be digitalised and made available to the public. The collection has been named 'The Oppel-Hammerschmidt Shakespeare Illustration Archive' in accordance with the terms of the Agreement of Donation of 9, 15, and 16 September 2005, and honouring the 16 March 1988 Delegation of Authority and Declaration of Intent by Frau Ingeborg Oppel, Prof. Oppel's widow and legal assignee. Vice-President Prof. Jürgen Oldenstein opened the proceedings by noting that 2008 had been a good year for international Shakespeare scholarship. For, in London, the site of the 'Theatre' in Shoreditch, where Shakespeare's company performed, had been unearthed, and in Mainz the Shakespeare Archive had gone online with thousands of illustrations. The Dean of the Faculty of Philosophy and Philology, Prof. Mechthild Dreyer, who mentioned that she herself had long been successfully employing interdisciplinary research methods, took particular pleasure in the transdisciplinary approach to research resolutely pursued by Prof. Hammerschmidt-Hummel. Prof. Clemens Zintzen (Cologne), former President of the Mainz Academy of Literature and Sciences, recalled highlights from the more than sixty-year-long history of the Shakespeare Illustration Archive. Prof. Kurt Otten (Heidelberg and Cambridge) drew an impressive portrait of Horst Oppel's personality as an academic and praised his influential books on Goethe and Shakespeare. He pointed out that Oppel's Shakespeare Illustration Archive, the basis for many a dissertation, had enjoyed great popularity around the world. Prof. Otten also delineated the academic career of Prof. Hammerschmidt-Hummel and her new findings regarding Shakespeare's time, life and work. Prof. Rüdiger Ahrens OBE (Würzburg) drew attention to Prof. Hammerschmidt-Hummel's research results, directly or indirectly arising out of her work on the Shakespeare Illustration Archive. This research had centred on proving the authenticity of four visual representations of Shakespeare (the Chandos and Flower portraits, the Davenant bust and the Darmstadt Shakespeare death mask); solving the mystery around Shakespeare's 'Dark Lady'; and establishing the dramatist's Catholic religion. Prof. Hammerschmidt-Hummel reported on her 'Shakespeare Illustration' project, describing the nature, dimensions and significance of the Archive's pictorial material, which relates to all of Shakespeare's plays and stretches over five centuries. She explained that the digital 'Oppel-Hammerschmidt Illustration Archive' was an addition to the three-volume edition she had compiled, authored and edited for publication in 2003. Unlike the print version, however, the digital collection had only been partly editorially prepared. It represented source material and a basis for further work. Hammerschmidt-Hummel expressed her thanks to the Head of the Central University Library, Dr Andreas Anderhub, for his untiring commitment. After the initial donation had been made, he had entered enthusiastically into setting up the necessary contacts, getting all the work underway, and clearing the legal hurdles. Hammerschmidt-Hummel was especially grateful to University of Mainz librarian Heike Geisel, who had worked for nearly five years to carry out the large-scale digitalization of a total of 8,800 items. Frau Geisel was also extremely resourceful in devising ways of making the collection yield even more, e.g. by classifying and cross-linking the data, assembling clusters of individual topics that lend themselves to research, and (in collaboration with the art historian Dr Klaus Weber) making the archive's index of artists compatible with the data-bank of artists held by the University of Mainz Institute of Art History. In addition, she compiled an extremely helpful 'users' guide' to the new digital collection. Frau Geisel had enjoyed invaluable support from Dr Annette Holzapfel-Pschorn, the leading academic in the Central IT Department at the University, who set up an intelligent, most impressive Web interface using the latest application technologies. Frau Geisel and Dr Holzapfel-Pschorn were highly praised for their convincing demonstration, using illustrations to Hamlet, of how to access this well-devised and exceptionally user-friendly Web version. For legal reasons, Prof. Hammerschmidt-Hummel pointed out, the collection could not be released for open access on the internet. The media - as Dr Anderhub stressed in his foreword - had shown great interest in the new digital collection of thousands of Shakespearean illustrations (cf. Benjamin Cor's TV feature in "Tagesthemen", 17 November 2008, presented by Tom Buhrow). The ‘Oppel-Hammerschmidt Shakespeare Illustration Archive’ should also meet with particular interest not only among academic specialists, but also among the performers of the arts and persons active in the cultural realm in general, as well as theatre and film directors, literary managers, teachers, and countless Shakespeare enthusiasts.

Ventilation/perfusion SPECT or SPECT/CT for lung function imaging in patients with pulmonary emphysema?

PURPOSE To evaluate the utility of attenuation correction (AC) of V/P SPECT images for patients with pulmonary emphysema. MATERIALS AND METHODS Twenty-one patients (mean age 67.6 years) with pulmonary emphysema who underwent V/P SPECT/CT were included. AC/non-AC V/P SPECT images were compared visually and semiquantitatively. Visual comparison of AC/non-AC images was based on a 5-point likert scale. Semiquantitative comparison assessed absolute counts per lung (aCpLu) and lung lobe (aCpLo) for AC/non-AC images using software-based analysis; percentage counts (PC = (aCpLo/aCpLu) × 100) were calculated. Correlation between AC/non-AC V/P SPECT images was analyzed using Spearman's rho correlation coefficient; differences were tested for significance with the Wilcoxon rank sum test. RESULTS Visual analysis revealed high conformity for AC and non-AC V/P SPECT images. Semiquantitative analysis of PC in AC/non-AC images had an excellent correlation and showed no significant differences in perfusion (ρ = 0.986) or ventilation (ρ = 0.979, p = 0.809) SPECT/CT images. CONCLUSION AC of V/P SPECT images for lung lobe-based function imaging in patients with pulmonary emphysema do not improve visual or semiquantitative image analysis.
