CANDIANI, GIANLUCA. "HLJEB SA SEDAM KORA ovvero IL PANE DALLE SETTE CROSTE. Lavoro e identità tra i minatori illegali di carbone di Zenica (BiH): etnografia di una realtà post-socialista." Doctoral thesis, Università degli Studi di Milano-Bicocca, 2021. http://hdl.handle.net/10281/305212.
Full textAbstract:
Una vasca da bagno risale lentamente, come sospinta dal soffio di Madre Terra, dalle viscere di una collina metallifera nei pressi di Zenica, nella Bosnia centrale. Un carico di carbone fumante appena estratto è pronto per essere setacciato e caricato su un vecchio camion dell’esercito jugoslavo dalla squadra di minatori che opera in superficie. È così che, dalle profondità della terra dove trovano lavoro centinaia di minatori illegali bosniaci, nasce un florido commercio parallelo di carbone che andrà ad alimentare caldaie e cucine di migliaia di famiglie in tutto il Paese. Ciò avviene in totale assenza di contratti, norme di sicurezza, tutele assicurative o garanzie di alcun tipo per i lavoratori.
Nella città considerata una «Jugoslavia in miniatura», modello del socialismo reale, trainata dalla sua acciaieria (Željezara Zenica) e dall’indotto metallurgico-minerario (più di 50.000 operai), fino agli inizi degli anni Novanta a inebriare l’ambiente economico e socio-culturale era il senso di sigurnost (sicurezza) e di fiducia nel futuro, sprigionate da un paradigma lavorativo fondato sulla Samoupravljanje (Autogestione). Questo metteva al centro la figura dell’uomo-operaio, autentico simbolo del progresso e del miglioramento delle condizioni di vita e lavoro avvenuto nel secondo Dopoguerra.
La dissoluzione della Jugoslavia e la Guerra che ne è seguita, ha portato al collasso del sistema-vita in cui gli abitanti di Zenica hanno vissuto per 50 anni. I lavoratori dell’acciaieria e delle miniere statali sono stati espulsi in massa dal mercato del lavoro senza alternative valide a livello occupazionale, sfavoriti da un contesto economico che orbitava intorno a una sola cometa: l’industria pesante.
Alla luce dei profondi mutamenti occorsi in Bosnia ed Erzegovina nelle ultime decadi, come sono andati riconfigurandosi dal punto di vista lavorativo e sociale, le traiettorie esistenziali degli abitanti di Zenica?
Ho cercato di avvicinarmi a questo interrogativo analizzando il prisma dell’economia sommersa che, negli anni dell’ultimo Dopoguerra e dei piani di aggiustamento strutturali in chiave neoliberista (apertura al libero mercato, privatizzazione delle proprietà sociali, deregolamentazione finanziaria, de-sindacalizzazione delle imprese), ha guadagnato un ruolo di primo piano nell’intero panorama economico-produttivo bosniaco (Divjak & Pugh, 2013).
Attraverso l’etnografia e l’esperienza di lavoro con i minatori illegali di Zenica, ho cercato di indagare la situazione inerente al mercato del lavoro (in particolare l’estrazione abusiva del carbone) e i temi ad esso correlati quali disoccupazione, emigrazione, diritti dei lavoratori, corruzione, sfruttamento, genere e processi di produzione di illegalità in questo particolare contesto post-industriale, post-bellico e post-socialista. L’estrazione illegale dell’oro nero bosniaco, unitamente all’interesse per le questioni che riguardano il complesso e sfaccettato quadro economico-sociale e politico-culturale del Paese, mi ha portato ad intercettare il filone di studi delle Artisanal and Small Scale Mining (ASM), da cui la presente tesi ha attinto parte dell’impalcatura teorica.
Come primo progetto di studi in ambito europeo sulle ASM il lavoro non gode di una letteratura d’area cui appoggiarsi, pertanto l’impianto teorico prenderà spunto da più fonti, rinunciando ad ogni pretesa di esaustività. La speranza è semmai quella di contribuire al dibattito accademico cercando di rendere, attraverso l’etnografia, da un lato la complessità delle nuove relazioni sociali ed economiche legate ad un mutato universo di significati in cui agiscono gli attori del panorama estrattivo artigianale zeničano, dall’altro di presentare le prospettive future di un vasto mondo del lavoro illegale, connesso a scelte politiche ed economiche non solo di carattere locale ma soprattutto federale, nazionale e globale.A bathtub rises slowly, as pushed by the Mother Earth’s breath, from the bowels of a metallic hill near Zenica, in central Bosnia. A cargo of freshly extracted steaming coal is ready to be sieved, stowed in 50 kg bags, and loaded into an old Yugoslav army truck by the miners working outside. Here, from the depths of the earth where hundreds of Bosnian illegal miners find work, a thriving parallel coal trade is born, in order to feed stoves, boilers and kitchens for thousands of families across the country. This occurs in the total absence of contracts, any kind of safety regulations, insurance protections or guarantees for the workers. During the Tito period, this city was considered a «miniature Yugoslavia», a true model of real socialism, driven by both its steel mill (Željezara Zenica) and the metallurgical-mining industries (which employed more than 50,000 workers). Until the beginning of the nineties, the economic and socio-cultural environment was enhanced by the pervasive sense of sigurnost (security) and the confidence in the future, released by a work paradigm based on Samoupravljanje (Self-management). This was focused on the man-worker, an authentic symbol of progress and improvement of living and working conditions, which took place in the second post-war period. The dissolution of Yugoslavia and the consequent war led to the collapse of this life-system, known by the inhabitants of Zenica for 50 years. The steel mill and State mines workers were all expelled from the labor market without valid alternatives in terms of employment. They were also penalized by an economic context based on a single, great and bright direction: the “heavy” industry, fundamental and everlasting point of reference for thousands of workers and citizens. Considering the deep changes occurred in Bosnia and Herzegovina in the last few decades: how the lives of the Zenica (the "Incandescent City") inhabitants have been set up again from a working and social point of views? I tried to approach this question by analyzing the condition of the underground economy. During the last postwar period and throughout the structural adjustment plans in a neoliberal view (for example, the opening to the free market, privatization of social property, financial deregulation, de-unionization of companies), this hidden economy has gained a leading role in the entire Bosnian economic-productive landscape (Divjak & Pugh, 2013). Considering the ethnography and my experience working with the illegal miners in Zenica, I wanted to investigate the situation of the labor market (in particular illegal coal mining) and the related issues, such as unemployment, emigration, rights of workers, corruption, exploitation, gender, conflicts, cooperative methods and illegal production processes in this particular post-industrial, post-war and post-socialist context. The illegal "private" extraction of Bosnian black gold, together with my interest in issues like the complex and diverse economic-social and political-cultural framework of the Country, led me to the specific studies of the Artisanal and Small Scale Mining (ASM), from which the theoretical framework of this thesis is based. As the first European study project on ASM, this work does not have a literature background to rely on, therefore the theoretical framework will be inspired by different sources, without claiming to be exhaustive. My aim (and hope) is to contribute to the academic debate. Through ethnography, I am trying to explain the complexity of the new social and economic relationships connected to the changed life meanings in which the artisanal miners of Zenica are working now. Also, I want to present the future possibilities for the large world of illegal work, deeply linked to political and economic choices, not only local but especially the federal, national and global ones.

Resumo: O estudo da radiação cósmica é de extrema importância para a astrofísica. Partículas oriundas de diferentes locais, tanto do sistema solar, quanto fora dele, chegam constantemente à Terra, carregando muitas informações a respeito da sua origem. Quando essas partículas encontram a atmosfera terrestre da-se início a uma cascata de partículas secundárias resultantes da interação do raio cósmico primário com a atmosfera. Dessa chuva de partículas secundárias, os múons são as partículas carregadas mais abundantes que chegam à superfície da Terra. Múons são altamente penetrantes, o que pode representar um problema muito grande em ex- perimentos, mesmo que subterrâneos, de outras partículas. Devido ao seu grande número, eles se tornam extremamente necessários em reconstruções de chuveiros atmosféricos para obtenção de informações a respeito da partícula primária. Tendo conhecimento de suas características, como por exemplo fluxo, ruídos em experimentos podem ser tratados e outros estudos podem ser otimizados. A intensidade de múons na superfície terrestre é bem conhecida como sendo anisotrópica e com uma dependência do ângulo zenital da forma ? (?) = ?0?osn(?). Por simplicidade nos cálculos, este expoente n é freqüentemente utilizado com valor igual a 2, mas estudos mostram que este parâmetro possui dependência com a posição geográfica e com a faixa de energia dos múons em questão. Esta dissertação propõe um método simples para a precisa determinação do expoente n e da intensidade vertical de múons simultaneamente, que pode ser realizado de maneira rá- pida em qualquer laboratório de raios cósmicos, utilizando detectores de partículas, que juntos formam o chamado Telescópio de Múons. Como resultado da aplicação do método no Laboratório de Léptons em Campinas - SP, foi obtido um valor de n de aproximadamente 2.30 e um valor para a intensidade vertical de múons em torno de 146.40? z/m2sr. Dados muito satisfatórios e de acordo com outros experimentos semelhantes já realizados anteriormente no Laboratório. O método também foi aplicado no Fermilab, localizado nos Estados Unidos. Nesta outra loca- lização geográfica, os resultados diferiram bastante dos obtidos em Campinas, com n aproxima- damente 3.66 e intensidade vertical de múons em torno de 158.33 ? zm-2sr-1. O mesmo experimento com o telescópio será realizado em outras posições geográficas afim de se verificar o comportamento do expoente n e da intensidade vertical de múons em diferentes locais
Abstract: The study of cosmic radiation is of utmost importance to astrophysics. Particles from different locations, from inside the solar system, and outside it, constantly arrive on Earth, carrying a lot of information about its origin. When these particles arrives to Earth¿s atmosphere they initiate a cascade of secondary particles resulting from the interaction of the primary cosmic ray with the atmosphere. From this rain of secondary particles, muons are the most abundant charged particles that reach the Earth¿s surface.Muons are highly penetrating, which can be a very big problem in some experiments, even if underground, of other particles. Because of their large number, they become extremely necessary in reconstructions of air showers to obtain information about the primary particle. Having knowledge of its characteristics, such as flux and distribution, noise in some experiments can be treated and other studies can be optimized.Muon intensity in the Earth¿s surface is well known to be anisotropic and has dependence on the zenith angle of ? (?) = ?0 cosn(?). For simplicity in the calculations, this n exponent is often used with a value of 2, but studies show that this parameter has dependence on the geographical position and on the energy range of muons in question. This dissertation proposes a simple method for accurate determination of the exponent n and muon vertical intensity simultaneously, that can be determined quickly in any laboratory cosmic rays using a particle detector, which was called Muon Telescope. As a result of the application of the method on the Leptons Laboratory, in Campinas - SP - Brazil, the value for n that was obtained is about 2.30 and a value for the vertical intensity of muons around 146.40? z/m2sr. This data is very satisfactory and according to similar experiments previously conducted at the Laboratory.This method was applied on Fermilab, located at the United States. On this new geographical location, the results were different from that obtained at Campinas, with n about 3.66 and the vertical intensity around 158.33 ? zm-2sr-1.The same experiment with the telescope will be held in other geographical locations in order to check the n exponent behavior and the muon intensity at different locations

Full textAbstract:
The purpose of this thesis is to examine the identity, competences and professional development of corporate librarians. I have done an empirical study based on semi structured interviews with 11 information professionals who were working at Astra Zeneca at the time of the re-organizations of the company in 2009 which ultimately led to the closing of the libraries. I have also examined the views on competences and professional development of librarians in general, both in Sweden and in Denmark. I have used Thomas Brante’s theories on profession types as well as Anders Ørom’s theories on librarian identities as my theoretical framework. The study finds that the respondents have a strong sense of identity as librarians. The interviews revealed that corporate librarians can be considered as having higher status compared to other librarians and that it is primarily based on the fact that the compensation is better in the private sector. The interviews also revealed that being service minded, thorough, social as well as of a curious disposition are regarded as key skills among librarians. The study finally concludes that teaching is an important part of the librarian identity and that Ørom’s model in general proved inadequate when applied to corporate information professionals.

Full textAbstract:
Conselho Nacional de Desenvolvimento Científico e TecnológicoA Mata Atlântica é um dos mais ricos ecossistemas em termos de diversidade biológica do mundo. Ela é representada por vários tipos de vegetações, além de ser caracterizada pelo alto grau de endemismo. Atualmente, esta floresta, se encontra bastante fragmentada, restando apenas 7,5%. Apesar disso, ainda mantém níveis extremamente altos de biodiversidade e endemismo. Contudo, este bioma, provavelmente, é o mais devastado e seriamente ameaçado do planeta. Apesar da importância do estudo sobre Mata Atlântica, pouco se conhece dos processos físicos, químicos e biológicos existentes acima e abaixo do dossel. O estudo da radiação solar é importante para entender os diversos processos físicos, químicos e biológicos que ocorrem na biosfera, em particular em floresta. Ainda no ambiente de floresta a radiação solar se destaca entre outros fatores, sendo fundamental nos processos de fotossíntese, aquecimento do ar e da superfície e evapotranspiração. O processo de fotossíntese ocorre apenas em parte do espectro da Radiação Solar, compreendido entre os comprimentos de onda eletromagnética de 0,4 a 0,7 μm e denominada de Radiação Fotossinteticamente Ativa (PAR). Com base no exposto, o objetivo é caracterizar a evolução temporal da Radiação Solar Global (Rg) e Fotossinteticamente Ativa acima e abaixo de um fragmento remanescente de Mata Atlântica no Estado de Alagoas. O estudo foi realizado, no período de outubro/2009 a setembro/2010, com a obtenção dos dados (Rg, PAR, PAR refletida e precipitação) provenientes de uma torre micrometeorológica (10º17 36 S, 36º17 24 W) de 26 metros instalada numa área de floresta de Mata Atlântica. A área de estudo está localizada na Reserva Particular do Patrimônio Natural (RPPN) Lula Lobo I inserida na fazenda Capiatã A, pertencente à Usina Coruripe Açúcar e Álcool S/A, no município de Coruripe, Alagoas. Verificou-se que a radiação solar incidente (Radiação Solar Global Externa (Rg_Ext) e Radiação Fotossinteticamente Ativa na parte Externa (PAR_Ext)) seguem a sazonalidade imposta pelo movimento aparente do Sol. Na época seca observou-se os maiores registros de Rg_Ext e PAR_Ext, com respectivas médias superiores a 900 W m-2 e 600 W m-2. Enquanto que, na época chuvosa foram registradas as menores médias, com Rg_Ext abaixo de 500 W m-2 e PAR_Ext inferior a 300 W m-2. Entretanto, uma pequena fração da radiação solar atinge o solo da floresta, ou seja, menos de 8% incide sobre a superfície. A radiação solar que incide no chão da floresta tem grande dependência do ângulo zenital (Z) e da estrutura do dossel. Notou-se também grande influência do Z na Rg_Ext e PAR_Ext, onde se verificou que quanto maior Z, menores são os valores destas componentes, em razão do maior caminho ótico que os raios solares tem que percorrer para atingir à superfície.

Title: Are Mergers and Acquisitions a successful way of growth- A Case Study of AstraZeneca
Subject: Bachelors thesis within the field of Business Management, School of Economics and Engineering, Halmstad University, Sweden
Authors: Frida Ekenberg & Simon Utas
Supervisor: Christer Norr
Objective: The objective of this thesis is to analyse the effects of a fusion from a business perspective. Furthermore, a case study approach is used in order to identify factors that have been reached by AstraZeneca through the joint venture.
Working Structure: The thesis is based on a qualitative case study of AstraZeneca. The empirical data is based on interviews with people who were working at the company at the time of the merger and people within the field of the stock market. Furthermore, studies of documents, articles, press releases and annual reports have been used as a framework for the empirical data.
Conclusion: The results from our study are not unequivocal. However, today AstraZeneca is considered to be a successful joint venture since the company is one of the greatest market leaders in the pharmaceutical industry. Even though, the analysis state that the deal created both financial and international advantages, its effects on the share price movement are not equivalent. Furthermore, the share price movement is only a short term effect and since synergy effects were accomplished concurren

Full textAbstract:
AstraZeneca is one of the largest biopharmaceutical companies in the world, and one of the facilities they have is located in Gärtuna, Södertälje. The facility itself is very big with a floor area of 560.000m2 and has a complex energy system. Caverion holds a facility management contract at AstraZenca, hence operates some of the energy system. The energy investigation of this thesis is part of the work of Caverion to ensure a sustainable energy system in Gärtuna. The energy investigation will include mapping of the energy distribution, seeking for potential of improvements and carry out suggestions for energy optimizations. The methods used during the investigation was a literature study, interviews with personnel of both Caverion and AstraZenca, study of the energy system and calculations relevant to the field of study. The mapping of the energy system includes the heat, steam and cooling distribution. When the mapping of the system was done it was clear that the areas with most potential for improvements were the steam and cooling distribution.The mapping of the steam distribution shows a loss of nearly 46% of the steam at year 2014 and the corresponding cost of about 13,640,000 SEK. Even though the steam distribution showed great potential for improvements, it was found that the work of investigating the system would be too difficult for the scope of the thesis. The cooling distribution however is more accessible and the potential is still high due to low coefficient of performance. Two suggestions for energy optimizations were carried out. The first suggestions involves upgraded electric fan motors for some of the cooling towers, and the second suggestion is to modify existing dry coolers in benefit to utilize free cooling during winter period. The fan motor upgrade based on calculations is estimated to result in a yearly energy saving of at least 1526 MWh and a corresponding cost saving of at least 800,000 SEK per year after the pay-off time (9 months). The dry cooler modification based on calculations is estimated to result in a yearly energy saving of 3053 MWh and a yearly cost saving of 2,083,449 SEK after the pay-off period of 5 months. The investigation carried out in this thesis is relevant to both Caverion and AstraZeneca as it points out the areas with potential of improvements and also gives suggestions on energy optimizations that will reduce energy consumption and result in energy cost savings.

Full textAbstract:
Two populations of Barbados Zenaida dove (Zenaida aurita) have in previous work been found to use two radically different modes of feeding competition. The St. James (StJ) population is territorial; it competes aggressively with conspecifics but scramble competes with heterospecifics. The Deep Water Harbour (DWH) population forages nonaggressively in large homospecfic flocks. Earlier studies linking these social differences with differences in individual and social learning suggest that Z. aurita is ideal for testing predictions from Brown's (1964) theory of economic defendability. Firstly, the hypothesis that resource defence will increase as the spatial clumping and temporal predictability of a resource increases was tested at 6 sites at DWH with a randomized complete block design. Secondly, spatial distribution of food was manipulated at both DWH and StJ in an attempt to alter the mode of foraging competition at DWH from scramble to interference, and to elicit group-feeding in the otherwise territorial StJ doves. As predicted, rates of aggression per intruder were highest for those sites at DWH receiving a spatially clumped and temporally predictable food source. Unlike those at DWH, doves from StJ did not modify their mode of foraging competition in response to variations in spatial distribution, but rather as a consequence of increased resource density. Interference competition appears to be the default strategy for Zenaida doves, with birds switching to scramble competition when a threshold of resource density is reached, only to revert back to aggressive defence when the spatial clumping and temporal predictability of food increases.

Na presente Dissertação pretende-se analisar o pensamento político de Francisco Salgado
Zenha e a sua importância na luta pela democratização de Portugal antes e depois do 25 de
abril de 1974 e nasce da constatação de dois paradoxos:
O primeiro paradoxo reside no facto de Francisco Salgado Zenha ser um nome incontornável
da história portuguesa da segunda metade do século XX pela sua ação na luta pela Liberdade,
durante o Estado Novo e na consolidação do regime democrático saído da Revolução dos
Cravos; mas que, não obstante a sua importância, o seu nome parece votado a um certo
esquecimento; sendo a contradição paradoxal no facto de, nos primeiros anos da nossa
democracia, Mário Soares, seu amigo, companheiro e cúmplice de longa data o ter
classificado como a “consciência moral do Partido Socialista”, mas que viria a ser alvo de um
processo disciplinar por parte do partido que ambos ajudaram a fundar, assistindo-se, a partir
desse momento a seu progressivo afastamento que culminaria na sua candidatura a
Presidente da República precisamente contra Mário Soares.
Procura-se dar a conhecer não só o percurso pessoal, profissional e político de Salgado Zenha,
mas sobretudo trazer aos nossos dias o seu legado, com especial relevância para ética que,
para ele, deveria estar sempre presente na Política, patente na intransigente defesa dos
princípios, valores e ideais porque norteou a sua vida, numa altura em que a política parece
mais norteada pela defesa de interesses privados do que por princípios, valores e ideais.The present text aims to analyze the political thought of Francisco Salgado Zenha and its importance in the struggle for democratization of Portugal before and after the 25th April 1974 and is born from the recognition of two paradoxes: the first paradox is that although Francisco Salgado Zenha is an inevitable name in Portuguese History in the second half of the 20th century for its action in the fight for liberty, during the Estado Novo and in consolidating the democratic regime that appeared after 1974’s Portuguese Revolution; but that, notwithstanding its importance, his name is somehow lost in the memories of History; the second paradoxical contradiction in the fact that, in the early years of our democracy, Mário Soares, his friend, companion and longtime accomplice have classified as the "moral conscience of the Socialist Party", but that would be the subject of disciplinary proceedings by the party that both helped to found, being this moment the beginning of his progressive rupture that would culminate in his candidacy for the Presidency of the Republic precisely against Mario Soares. Seeks to inform not only the personal, professional and political career of Salgado Zenha, but above all bring to our days his legacy, with special relevance to ethics that, for him, should always be present in politics, patent in the uncompromising defense of principles, values and ideals that have guiden his life, at a time when politics seems more guided by the defense of private interests than by principles, values and ideals.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition.

Full textAbstract:
This dissertation presents a novel satellite timekeeping system which does not require on-board atomic clocks as used by existing navigation satellite systems such as GPS, GLONASS or the planned GALILEO system. This concept is differentiated by the employment of a synchronization framework combined with lightweight steerable on-board clocks which act as transponders re-broadcasting the precise time remotely provided by the time synchronization network located on the ground. This allows the system to operate optimally when satellites are in direct contact with the ground station, making it suitable for a system like the Japanese Quasi-Zenith Satellite System, QZSS. Low satellite mass and low satellite manufacturing and launch cost are significant advantages of this novel system. Two possible implementations of the time synchronization network for QZSS are presented. Additionally, the problem of satellite communication interruption is analyzed and a solution is presented. Finally a positioning and timing quality analysis, aimed to provide understanding of the actual timing quality requirements for QZSS, is presented.

Full textAbstract:
Data collected from zenith pointing radar is used to study the range dependence of some meteorological radar errors associated with different sampling methods between radar and gauges in stratiform precipitation. Errors due to the vertical variation of reflectivity such as those related with the bright band or with snow growth cause a much larger bias in radar estimates than those due to beam filling or gradients. The maximum useful range varies with the bright band height and the elevation angle program used, a CAPPI giving superior results especially for snow. The sudden changes in bright band height over short distances and the large scatter of its thickness limit the accuracy of current corrections for the vertical variation of reflectivity based on scanning radar data. The possibility of using a zenith pointing radar to obtain this correction is discussed.

Full textAbstract:
The Graduation thesis concerns with the topic of the transport of supplier -- customer operations in the pharmaceutical group Zentiva. At first the thesis describes in detail the legislative arrangement for the pharmaceutical group not only in the Czech Republic but also in the European Union. The reader gets the conception of the processing in the Purchasing department in the pharmaceutical company and also of the transport of raw materials to the production plants. Another part is dealing with the the distribution of pharmaceutical products (medicaments) to the several regions, where Zentiva is distributing its products. The most current and interesting subject matter in these days newly introduced distribution of consolidated products of Zentiva and Sanofi-aventis from the production plants to the several pharmacies in the Czech Republic. Sanofi-aventis ordered this new way of distribution to Zentiva, as Sanofi-aventis is the majority shareholder of Zentiva from the spring of 2009. The direct distribution of pharmaceutical products from the producer to pharmacies is very specific. Zentiva is not only the first pharmaceutical company in the Czech Republic but also one of the firsts companies in Europe, which will carry out this type of distribution beginning January 2010.

Full textAbstract:
This thesis examines the hypothesis that social learning in Zenaida dove (Zenaida aurita) functions primarily in a mixed species foraging context. The field study recorded foraging associations and interactions between Zenaida doves and other species. The Carib grackle (Quiscalus lugubris) was the most frequent foraging associate of Zenaida doves.The laboratory study consisted of two experiments where conflicting information about a novel food type and novel food-finding problem was provided simultaneously by a conspecific and a heterospecific (grackle) demonstrator. Both experiments showed that not only could Zenaida doves learn from another species, but that they preferred the heterospecific demonstrator over the conspecific. The results suggest that social information may be obtained more readily from foraging associations rather than interference competition and that the role of conspecifics may be overemphasized in cultural learning.

Full textAbstract:
A Paracoccidiodomicose (PCM), causada pelo fungo Paracoccidioides brasiliensis, é a principal micose sistêmica endêmica na América Latina. O agente etiológico da PCM apresenta dimorfismo termo-dependente crescendo na forma micelial a 25°C e na forma de levedura à 37°C. Os trabalhadores rurais do sexo masculino são os principais acometidos e a infecção ocorre provavelmente por inalação de propágulos de P. brasiliensis provenientes do solo. A pomba silvestre Zenaida auriculata é uma espécie campestre de formas delgadas com cerca de 21 cm, nas regiões sul e sudeste do Brasil, ocorre em vários hábitats, inclusive em cidades, e aparentemente explora diferentes tipos de recursos alimentares, tais como restos alimentares produzidos pelo homem, e alguns tipos de sementes de interesses econômicos. O grande número de indivíduos em cidades tem causado preocupações às autoridades em função do potencial de transmissão de patógenos, tendo a espécie como reservatórios de patógenos. A participação de outras espécies de animais na eco-epidemiologia da paracoccidioidomicose não está esclarecida. Este trabalho teve como objetivo avaliar a infecção em duas populações da pomba silvestre Z. auriculata pelo fungo P. brasiliensis, além de avaliar a resposta imune humoral. Duas pombas foram imunizadas com P. brasiliensis e produziram anticorpos IgY para gp43. As amostras de soro (n=113) de Z. auriculata capturadas em dois locais (Campus Universidade estadual de Londrina-UEL e cooperativa Integrada) no município de Londrina, Norte do Paraná, foram analisadas por ELISA indireto, usando gp43 como antígeno. A positividade observada foi de 83,7% em pombas capturadas no campus da Universidade Estadual de Londrina e 11% em pombas capturada na Cooperativa Integrada, sugerindo que a pomba Z. auriculata infecta-se facilmente com P. brasiliensis e poderia ser utilizada como animal sentinela.Paracoccidioidomycosis (PCM), the main systemic endemic mycosis in Latin America, is caused by Paracoccidioides brasiliensis. The fungus is thermal dimorphic and grows in mycelial form at 25°C and as yeast at 37°C. The infection occurs by inhalation of P. brasiliensis propagules probably from the soil and the disease affects mainly male rural workers. The wild dove Zenaida auriculata is frequent in southern and southeastern Brazil and occurs in various habitats, including cities, and apparently explores different types of food resources, such as food debris and some types of seeds of economic interest. The large number of individuals in cities has caused concern due to the potential transmission of pathogens. The objective of this study was to evaluate the infection the P. brasiliensis in two populations of Z. auriculata. Initially, two doves were immunized with P. brasiliensis inactivated yeast cells and produced IgY antibodies for gp43. The samples of the serum (n=113) from Z. auriculata captured in two locations (Campus State University of Londrina and Integrated Cooperative) in the municipality of Londrina, Northern Parana, were analyzed by indirect ELISA, using gp43 as antigen. The positivity observed was of 83,7% in doves captured in the campus of State University of Londrina and 11% in doves captured in Integrated Cooperative, suggesting that Z. auriculata dove is easily infected with P. brasiliensis and could be used as animal sentinels.

Sarbanes-Oxley Act, SOX, har inneburit stora förändringar för de företag som

kontroller av processer inom företaget har detta inneburit mycket arbete för
företagen och revisorer. Framförallt under införandet men även efteråt i det

I denna uppsats redogör vi för hur svenska företag ser på Sarbanes-Oxley Act

fram till våra slutsatser har vi intervjuat sex olika personer som på något sätt
kommer eller har kommit i kontakt med SOX. Det är svar från personer på
ABB, AstraZeneca, Autoliv, Ericsson samt Ernst & Young som varit grunden
i vårt arbete.
Det visade sig att de alla ansåg att SOX höjt kvaliteten i deras redovisning och
hjälpt dem att hitta felaktigheter i ett tidigare skede. Dock är det tveksamt om
regelverket motverkar de riktigt omfattande bedrägerier vi sett och kanske
även i fortsättningen kommer se.

Full textAbstract:
Previous work on feral pigeons (Columba livia) and zenaida doves (Zenaida aurita) suggests that both individual and social learning varies with type of competition: rapid non-aggressive feeding is associated with rapid individual learning as well as rapid social learning from the tutor types a bird usually feeds with in the field. Comparative learning tests, however, may be influenced by intervening variables like neophobia and tameness: tests are always run on captive animals by human experimenters using novel stimuli.This thesis compares pigeons to territorial and group-feeding zenaida doves on their response to novel stimuli in the field and in captivity, in the presence or absence of humans. In single cages, tameness and neophobia co-vary with learning: pigeons are more rapid than doves at learning, at interacting with a novel apparatus and at feeding in the absence of the human; territorial zenaida doves are slower than group-feeding doves on all three tests. Multiple regressions show that neophobia and tameness explain an important part of the variance in learning. These results are confirmed by a re-analysis of data previously obtained on finches (Whittle, 1996), where neophobia predicts individual learning which in turn predicts social learning.
In the field, however, neophobia has opposite effects: territorial zenaida doves now show the smallest effect of novel stimuli on feeding latency. Experiments that test evolutionary predictions about learning using captive animals are thus open to questions of internal and external validity: when we measure comparative performance on a captive learning test, is it really learning we are measuring and does it mirror, as it should, adjustment to environmental novelty in the field?

The experiment was conducted at the Kendall Site of the Walnut Gulch Experiment Watershed in southeastern Arizona during the 1990 growing season. A special apparatus for mounting a spectroradiometer and acquiring bidirectional reflectance data was constructed and used over a semi-desert grassland plot. For purposes of analyzing multidirectional vegetation spectral behavior, the Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) were calculated as a function of view angle and solar zenith angle throughout the growing season. The results have shown that the SAVI considerably minimized anisotropic behavior whereas the NDVI was very sensitive to both solar zenith and view angles. With further refinement the SAVI offers a technique whereby satellite measurements of vegetation activity could be further understood.

Full textAbstract:
The English coastal motor barge (ECMB) was an estuarial vessel with a limited sea-going capacity. It represented a unique line of maritime evolution carrying the small initial capital cost, minimal manning, and low operating costs of the spritsail barge (which had come to dominate lower North Sea cargo carrying under sail) directly into the second half of the 20th century. It avoided transition through the era of the steam engine and the crewing, costs and unionisation associated with it. This thesis is essentially a case study of a distinct class of tonnage. It aims to (a) record the development, growth and decline in use of the ECMB; (b) determine, set down, and quantify, those factors which allowed the ECMB to thrive as a distinct line of maritime development; (c) establish which environmental and financial factors gave rise to growth and success in an era when British - and Western European - shipping generally was in rapid decline; (d) set the extent of ECMB use in the context of (1) UK foreign trade, (2) the 'British' merchant fleet, (3) Continental competition; before much existing, unpublished, documentary evidence is lost for ever. It considers the end of Empire and changing patterns of trade, voyages, cargoes, freight rates, technical change, the cost of money in Britain, UK Inflation, and taxation, but also the contribution of increased regulation and changed UK government attitudes in the recent decline of the ECMB. It suggests that when the operation of the UK National Dock Labour Scheme acted to disadvantage major UK ports in competition with near-Continental rivals in loading and discharging ocean-going vessels, the ECMB had reached a stage of maturity and availability which facilitated the conversion of much UK trade into transhipment traffic moving via Continental ports. On entry of the UK into the EEC, a means of cheap short-sea bulk carriage was available.

Currently, the major errors in altimetry measure by sensors onboard satellites have been attributed to the propagation of the signal trough the dynamic atmosphere,which is divided between the ionosphere and the electrically neutral layer. This study aimed to evaluate the effects of the electrically neutral layer, consisting of troposphere, tropopause, stratosphere and part of stratopause, on signal of three satellites: ENVISAT, SARAL and Jason-2. The effect of tropospheric refraction can be modeled using in situ data from weather station, separating it into two parts: the delay due to the effect of dry gases and the delay due to the effect of water vapor, DTC and WTC, respectively. These corrections are considered as the most relevant ones, related to the study of inland waters. Errors in the continuity between correction data supplied by ECMWF model for the same orbit satellites have been detected, at some stations, indicating a non-homogeneity in corrections. Limitations in capturing the seasonality of WTC data in humid regions of the Amazon, featuring better results in regions with greater seasonal variation of moisture, aiming for the need for other sources of data, such as radiosondes for a better representation of the moisture profile of the atmosphere, by the meteorological model Saastamoinein have been observed. In addition, find mistakes that should not still in the current version of the GDR data were also observed in some sites studied in the Amazon. This fact stresses that it is need to pay more attention to the standardization of the data used in the various altimetry products.
Atualmente, os maiores erros nas medidas altimétricas realizadas por sensores a bordo de satélites são atribuídos à propagação do sinal pela atmosfera dinâmica, que compreende ionosfera e camada eletricamente neutra. Esse estudo objetivou avaliar e comparar os efeitos da camada eletricamente neutra, composta pela troposfera, tropopausa, estratosfera e parte da estratopausa, sobre os pulsos emitidos pelos radares altimétricos dos satélites ENVISAT, SARAL e Jason-2. O efeito da refração troposférica pode ser modelado, utilizando dados de estações meteorológicas in situ, separando-o em duas partes, o atraso devido ao efeito dos gases secos e o atraso devido ao efeito do vapor d’água, DTC (Dry Tropospheric Correction) e WTC (Wet Tropospheric Correction), respectivamente. Essas correções são consideradas as mais relevantes, no que se refere ao estudo de águas interiores. Observou-se a existência de uma descontinuidade entre dados da correção fornecidos pelo modelo ECMWF (European Center for Mediumrange Weather Forecast) para satélites de mesma órbita, em algumas estações, evidenciando a não-homogeneidade das correções utilizadas. Observou-se, também, que o modelo meteorológico de Saastamoinen apresentou limitações em captar a sazonalidade dos dados de WTC sobre regiões úmidas da Amazônia, apresentando melhores resultados em regiões com maior variação sazonal de umidade, apontando para a necessidade de outras fontes de dados, como radiossondagens para uma melhor representação do perfil de umidade da atmosfera. Além disso, erros que já não mais deveriam ser encontrados na atual versão dos registros de dados geofísicos GDR (Geophysical Data Records), ainda foram observados em alguns sítios estudados na Amazônia. Este fato sinaliza a necessidade de dedicar maior atenção à padronização dos dados utilizados nos diversos produtos altimétricos.

Energised by the evangelical influence in Britain, the foundation of missionary societies enabled missionaries to be sent during the nineteenth century to convert the heathen in different parts of the world. This thesis examines the involvement of women with the missionary societies. It considers how they made the transition from being unpaid assistants to the male missionaries to becoming missionaries in their own right by the end of the nineteenth century. By looking at the selection process and the journal of the Church of England Zenana Missionary Society (CEZMS), this thesis argues that while religious belief played a very considerable part in their motivation to become missionaries, women had also been enabled by the changes in the secular world of the nineteenth century.

Full textAbstract:
Neospora caninum é um protozoário, parasita intracelular obrigatório pertencente filo Apicomplexa e família Sarcocystidae. O parasita possui distribuição mundial e é responsável pela neosporose, uma doença primária de cães e bovinos, sendo considerada como uma das principais causas de abortamento em bovinos. Cães e outros canídeos são os hospedeiros definitivos e eliminam oocistos no ambiente. Vários animais domésticos e silvestres, incluindo aves, tem sidos descritos como hospedeiros intermediários, entretanto o papel desses animais no ciclo epidemiológico ainda é incerto. O objetivo do presente estudo foi avaliar se pombos da espécie Zenaida auriculata podem atuar como hospedeiros intermediários do N. caninum, contribuindo assim com a transmissão da doença. No primeiro experimento, 249 pombos Z. auriculata foram capturados em três diferentes áreas da cidade de Londrina, Paraná. Amostras de soro e cérebro foram coletados para a realização dos testes sorológicos e molecular respectivamente. Por meio da técnica de ELISA, 31,72% (79/249) das amostras foram positivas, com maior número de aves positivas capturadas em uma indústria de processamento de grãos. Não foi observado DNA do parasita utilizando a técnica de PCR em nenhuma das amostras de tecido cerebral. No segundo experimento, 18 pombos foram divididos em 4 grupos, G1, G2 e G3, composto por 5 animais cada, receberam 2x106 taquizoítos da cepa NC-1 do N. caninum pelas vias subcutânea, intramuscular e intraperitoneal respectivamene. G4, composto por 3 animais, permaneceu como grupo controle. A técnica de ELISA foi utilizada para verificar a cinética dos anticorpos contra o parasita após a inoculação. No sétimo e 14° dia, um animal dos grupos G1, G2 e G3 foram eutanasiados para detecção do parasita pela PCR. Após 28 dias, todos os outros animais foram eutanasiados e tecidos (cérebro, coração, fígado, pulmão, rim e músculo peitoral) foram coletados para análise de PCR e exame histopatológico. Foi realizado bioensaio em cães para verificar cistos na musculatura de pombos experimentalmente infectados. Quatro cães foram foram alimentados com tecidos de pombos inoculados previamente de somente um grupo. Exames coproparasitológico e imunológico foram realizados para avaliar a infecção nos cães. Todas as aves inoculadas soroconverteram após desafio, com maior produção de anticorpos nas aves inoculadas pela via intraperitoneal. Um animal do grupo 3 eutanaziado no 7 dia após inoculação foi positivo na PCR dos tecidos. Apenas um animal do G3 apresentou um infiltrado inflamatório mononuclear no pulmão e rim, compatível com neosporose no exame histopatológico. Nenhum cão soroconverteu ou eliminou oocistos durante o período experimental. Esse estudo verificou pela primeira vez a presença de anticorpos contra N. caninum em pombos Z. auriculata de vida livre, demonstrando que esses animais tiveram um contato prévio com o N. caninum. Nossos resultados também indicaram que a via intraperitoneal induziu infecção nos pombos, entretanto essas aves foram consideradas resistente à infecççao crônica. Estudos adicionais devem ser conduzidos, especialmente utilizando outros modelos de infecção, para avaliar a importância dos pombos Z. auriculata na epidemiologia da neosporose.Neospora caninum is a protozoan, obligate intracelular parasite that belongs to Apicomplexa phylum and Sarcocystidae family. The parasite has worlwide distribution and is resposible for neosporosis, a primarily in dogs and cattle, being considered as one of the major causes of abortion in cattle. Dogs ans other canids are the definitve hosts e shed oocysts in the enviroment. Many domestic and wild animals, including birds, have been described as intermediate host, however, the role of these animals in epidemiological cycle is uncertain. The aim of the present study was to evaluate if doves from Zenaida auriculata species can act as intermediate host of N. caninum, contributing with transmission of the disease. In the first experiment, 249 dove Z. auriculata were captured in three different areas from Londrina city, Paraná. Serum and brain samples were collected to perform serological and molecular tests respectively. By means of ELISA, 31.72% (79/249) of samples were positive, with higher number of positive birds captured in an soybean seed plant. It was not observed DNA from the parasite using the PCR technique in all brain tissue samples tested. In the second experiment, 18 doves were divided in 4 groups, G1, G2 and G3, composed by 5 animals each, received 2x106 tachyzoites from NC-1 strain of N. caninum by subcutaneous, intramuscular and intraperitoneal route respectively. G4, composed by 3 animals, remained as control group. ELISA technique was used to verify the kinetics of antibodies against the parasite after inoculation. On 7th and 14th day, one animal from G1, G2 and G3 groups, were euthanized to detect the parasite by PCR. After 28 days, all other animals were euthanized and tissue (brain, heart, liver, lung, kidney and pectoral muscle) were collected for PCR analysis and histopathological examination. Bioassay in dogs were performed to verify cysts in the musculature of doves infected experimentally. Four dogs were fed with doves tissue from only one group. Coproparasitological and immunological examination were performed to evaluate dogs infection. All birds inoculated seroconverted after challenge, with higher antibodies production in birds inoculated through intraperitoneal route. One animal from group 3 that was euthanized on 7th day after inoculation was positive in PCR from tissues. Only one animal from G3 showed an mononuclear inflammatory infiltrate in lung and kidney, which is compatible with neosporosis in the histopathology evaluation. None dogs seroconverted or shed oocysts during experimental period. This study verified for the first time the presence of antibodies against N. caninum in free-ranging doves Z. auriculata, showing that these animals had previously contact with N. caninum. Our results also indicated that intraperitoneal route induced infection in doves, however these birs were considered resistent to chronic infection. Aditional studies should be conducted, especially using other infection models, to evaluate the importance of Z. auriculata doves in the epidemiology of neosporosis.

Full textAbstract:
A mandate is “a business, or element of a business, in which the subsidiary participates and for which it has responsibilities beyond its national market” (Birkinshaw, 1996, p. 467). In the past MNCs set up subsidiaries as miniature replicas of the parent firm but with a changing global market the role of the subsidiary has developed into holding specific mandates. Much has been written about how subsidiaries gain mandates, but in this paper we focus on what causes a subsidiary to lose its mandate. By using AstraZeneca’s R&D unit in Södertälje as a case we examine the loss of mandates and to what extent technological capabilities are connected to the loss of mandates. The paper shows that explaining the loss of mandates is complex and requires consideration of several perspectives. We here provide a starting point for other researchers to continue upon.

Full textAbstract:
Nahum B. Zenil es reconocido primordialmente por su obra pictórica elaborada durante la década de los ochenta y los noventa. La crítica y la historia del arte han demarcado las interpretaciones que hasta ahora han caracterizado a sus piezas en dos posturas disímiles: la paternalista noción de la confesión como la liberación de una opresión íntima y la satanización de la escatología y la exhibición del cuerpo. La presente investigación tiene como objetivo brindar argumentos teóricos que revivan el valor crítico de su obra en los términos que siguen: la reiteración de la cita homosexual en sus autorretratos fragmentan la relación entre la normatividad del género y la identidad nacional.
Para este propósito, esta tesis propone un marco metodológico que desglosa la lógica de la matriz heterosexual en sincronía con la construcción de la mexicanidad. Es decir, el aparato discursivo que fomenta la congruencia entre una identidad sexual en conjunto con la noción de pertenencia a una cultura y a un territorio. Este análisis va de la mano de la teoría de la performatividad de Judith Butler y los estudios profusos sobre el nacionalismo y la identidad homosexual en México de Carlos Monsiváis.Nahum B. Zenil is recognized primarily for his paintings from the eighties and nineties. Art history and art criticism have circumscribed the interpretations that have characterized his pieces until the moment into two dissimilar stances: the paternalistic notion of confession as releasing an intimate oppression and the demonization of eschatology and exhibitionism of the body. This research aims to provide theoretical arguments to reinforce the critical value of his work in the following terms: the reiteration of homosexual citation in his self-portraits subverts the relationship between gender normativity and national identity. For this purpose, this thesis proposes a methodological framework that breaks the logic of heterosexuality in synchrony with the construction of mexican identity. That is to say, the discursive apparatus that promotes congruence between sexual identity in conjunction with the notion of belonging to a culture and a territory. This analysis is developed under the parameters of performativity exposed by Judith Butler and the profuse studies on nationalism and homosexual identity in Mexico elaborated by Carlos Monsivais.

Full textAbstract:
I present a simulation model that should be a useful tool for risk assessment of the impact of insecticide inhibitors of cholinesterase (ChE) applied in irrigated agricultural fields on non-target wildlife. I developed the model as a compartment model based on difference equations (ÃÂt = 1 hour) and programmed with Stellaî VII software. Conceptually the model is compartmentalized into six submodels describing the dynamics of (1) insecticide application, (2) insecticide movement into floodable soil, (3) irrigation and rain, (4) insecticide dissolution in water, (5) foraging and insecticide intake from water, and (6) ChE inhibition and recovery. To demonstrate application of the model, I simulate historical, current, and âÂÂworst-caseâ scenarios, that examined the impact of ChE-inhibiting insecticides on white-winged doves (WWDO - Zenaida asiatica) in the Lower Rio Grande Valley of Texas (LRGV), USA. To my knowledge, there are no field data verifying that the cause of ChE deprivation in WWDO is due to the ingestion of ChE-inhibiting insecticide residues dissolved in drinking water. I parameterized the model to represent a system composed of fields of cotton, sorghum, corn, citrus, and brushland that encompasses the activity range of a WWDO in the LRGV. I simulated situations representing the typical scenario of WWDO using irrigated crop fields in the absence and in the presence of rain. I also simulated âÂÂworst caseâ scenarios in which methyl parathion was applied at high rates and high frequency. Based on results of the simulations, I conclude that it is unlikely that WWDO are seriously exposed to ChE-inhibiting insecticides by drinking contaminated water. Only in rare cases, for example, when a rain event occurs just after the application of insecticides, are levels of ChE inhibition likely to approach diagnostic levels (20 %). The present simulation model should be a useful tool to predict the effect of ChE-inhibiting insecticides on the ChE activity of different species that drink contaminated water from irrigated agricultural fields. It should be particularly useful in identifying specific situations in which the juxtaposition of environmental conditions and management schemes could result in a high risk to non-target wildlife.

O posicionamento com GPS (Global Positioning System), consiste basicamente na determinação de distâncias entre satélites e receptores, obtidas por meio de observações de sinais de rádio-freqüência. Entre os vários erros que estão presentes nessas observações, encontra-se o atraso dos sinais causado pela influência do vapor d’água atmosférico. Depois de minimizados os demais erros, o atraso troposférico pode ser estimado a partir das observações GPS. Estas estimativas, além de serem utilizadas para avaliar os modelos que tratam os efeitos da troposfera, podem ser convertidas em estimativas do vapor d’água integrado na atmosfera (IWV-Integrated Water Vapor). Para essa conversão, utiliza-se uma relação entre essas quantidades baseada na temperatura média da coluna vertical troposférica. Este trabalho tem por objetivo apresentar a aplicação do GPS na quantificação do vapor d’água atmosférico e uma metodologia para avaliar a modelagem do atraso zenital troposférico. Para isso, campanhas de radiossondagens e coletas simultâneas de observações GPS foram realizadas. Os resultados, na estimativa do vapor d‘água atmosférico, apresentaram boa compatibilidade com os valores fornecidos pelas radiossondas (EMQ de 2 kg/m2), e são similares aos valores encontrados na literatura. Quanto à avaliação da modelagem troposférica, os resultados indicam que a metodologia proposta apresentou-se adequada.
The GPS (Global Positioning System) positioning basically consists on determining the distances between satellites and receivers that are obtained by observing radio-frequency signals. There are several errors present in these observations. Among them we can find the delay of those signals caused by atmospheric water vapor. The tropospheric delay can be estimated by GPS observations processing after minimizing other errors. These estimates can be used to evaluate the models that attempt to reduce the tropospheric effects and may also be transformed into estimates of integrated water vapor (IWV). In this transformation is used a relationship between the delay and IWV values based on the tropospheric mean temperature. The main aims of this work are to present the GPS application related to atmospheric water vapor quantification and to propose a methodology to evaluate the zenithal tropospheric delay modeling. Launching radiosonde campaigns with simultaneous collections of GPS observations were accomplished.

Resumo: O dramaturgo alemão Heiner Müller (Eppendorf, 1929 -) compreende o teatro como o "laboratório da imaginação social". Essa assertiva implica uma consideração e crítica de seus pressupostos materiais, do aparelho teatral como instituição e seus limites, avançando gradualmente até o Espírito da Época ("Zeitgeist"). Nesse sentido, a experiência dramatúrgica alude ao conjunto da experiência social como seu "órgão" de autoreflexividade democrática, não apenas como decalque do existente, mas como um instrumento de descoberta e extensão de suas possibilidades e do seu vir-a-ser, de suas reservas imaginárias. Em meio ao turbilhão de meios tecnológicos, o anacronismo da forma teatral permanece como uma das últimas formas de relação imediata de nossa espécie. A reflexão sobre o "texto" da História é, portanto, a matriz de seu projeto dramatúrgico e a maneira pela qual se tece representa a produção da própria subjetividade como uma consciência de si e dos estratos que compõe sua temporal idade impura; mas é também a produção de seu "inconsciente", de seus recalques e do esquecimento. O relógio da História, para Müller, corre em sentido inverso do presente até atingir a estrutura mitológica que "fecunda", por assim dizer, este texto. Equilibrando-se entre a reflexão histórica, saturada de presente e articulada numa complexa noção de material artístico como "fragmento sintético" - um trabalho sobre as fraturas, descontinuidades e imprecisões das obras do passado, sobre a "inércia" que se revela em sua traditio -, e a necessidade em "olhar no branco dos olhos da Historia", como entende a capacidade política em seu sentido pleno, além da gravitação das ideologias e da política como esfera da instrumentalidade e engenharia socialmente eficaz, o olhar de Müller para o zênite da História é a ruptura de sua continuidade, a primazia da visão epifânica que transfigura e intensifica seus significados. Para Müller, este instante não é produto do acaso mas, incorporando a noção de Carl Schmitt de' seu ensaio Hamlet ou Hécuba: a irrupção do tempo no jogo, a formação de uma constelação trágica pela irrupção do tempo empírico na cena. Essa intrusão implode a moldura formal, colocando em movimento camadas profundas da experiência histórica sob o chão do presente. A afirmação de um sujeito histórico universal nos ensaios produzidos por Heiner Müller durante os anos setenta e oitenta é também correlata de um conceito de experiência genuína ("autentische Erfahrung") no campo da arte. Entretanto, a ênfase na substancial idade desse sujeito não resiste muitas vezes ao próprio paradigma intelectual em que se move e à maneira pela qual se articula, desfazendo-se como fantasmagoria. Os anos Honecker (1971-1989) caracterizam-se por uma deslegitimação progressiva da RDA nos planos interno e externo. Essa perda de horizonte utópico ("Utopieverlust") traduziu-se, em parcela considerável da inteligência leal da RDA, por uma conversão de paradigma conceitual ("Paradigmawechsel"). O foco da crítica desvia-se do campo do socialismo real para o âmbito civilizatório. Como parte desse complexo, pode-se pensar a dramaturgia de Heiner Müller como um instante privilegiado da apropriação da Dialética do Esclarecimento (1947) na RDA, cujo impacto, embora tardio, foi decisivo nessa conversão. Antes de representar a recepção pontual de um livro. A Dialética do Esclarecimento parece oferecer anacronicamente as categorias práticas de uma experiência de secularização intelectual a toda uma geração, através da desilusão ("Enttãuschung") com um espaço político cada vez mais restrito e suplantado pelo gerenciamento tecnocrático da economia, depois do fechamento da fronteira em 1961. De modo mais atento, seria possível perceber na terminologia crítica de Müller a restauração de figuras típicas do pensamento vitalista alemão de fins do XIX, tangenciando muitas vezes um diagnóstico conservador de crítica à modernidade. Se a derrocada do socialismo não deixava outra alternativa senão o avanço civilizatório, o teatro tardio de Müller e sua reflexão invocam poderes elementares e um culto dionisíaco para conjurar o presente. Esse investimento semântico anacrônico é incompatível com o próprio caráter descontínuo de sua escrita, de sua fragmentação. Contabilizando também para si a vantagem de estar à margem do debate ideológico, a noção de experiência em Heiner Müller transita em um "jargão de autenticidade" (Adorno) que extropola do campo da crítica estética para implicar o conjunto da cultura como "corretivo" de suas reservas utópicas. Essa incongruência é o foco de minha análise
