O presente trabalho teve como objetivo avaliar as características físico-químicas e de aceitação sensorial de diferentes produtos cárneos elaborados com adição de fibra de ervilha como substituto parcial de carne (visando redução de custos no produto) e de gordura (visando a elaboração de um produto mais saudável). Foram processados quatro diferentes produtos cárneos (nuggets, hambúrguer, apresuntado e salsicha), onde cada um apresentou as seguintes formulações: nuggets (Nuggets Controle (NC) - formulação semelhante à comercial, Nuggets Fibra/ Menos Carne (NFMC) - redução de 10% de carne e adição de 2 % de fibra de ervilha e Nuggets Fibra/ Menos Gordura (NFMG) - redução de 10 % de gordura e adição de 2% de fibra de ervilha), hambúrguer (Hambúrguer Controle (HC) - semelhante à formulação comercial; Hambúrguer Fibra/ Menos Carne (HFMC) - redução de 5% de carne e adição de 1 % de fibra de ervilha e Hambúrguer Fibra/ Menos Gordura (FMG) - redução de 7 % de gordura e adição de 1,0 % de fibra de ervilha), apresuntado (Apresuntado Controle (AC) - semelhante à formulação comercial e Apresuntado Fibra/Menos Carne (AFMC) - redução de 5% de carne e adição de 1% de fibra) e salsicha: (Salsicha Controle (SC) - semelhante à formulação comercial; Salsicha Fibra/Menos Carne (SFMC): redução de 5% de carne bovina e adição de 2% de fibra de ervilha e Salsicha Fibra/ Menos Gordura (SFMG) - redução de 7 % de gordura e adição de 2,0 % de fibra de ervilha). Após o processamento os produtos foram caracterizados quanto à composição centesimal, cor objetiva, perfil de textura, perda de peso após a fritura (nuggets), perda de peso por cocção (hambúrguer), redução do diâmetro (hambúrguer), perdas por gotejamento (apresuntado), rendimento do produto (salsicha), estabilidade da emulsão (salsicha) e avaliação sensorial (teste de aceitação com escala hedônica de nove pontos). Para os nuggets as formulações NFMC e NFMG apresentaram pH superior (p<0,05) ao controle, e a formulação NFMG apresentou maior (p<0,05) dureza, quanto à porcentagem de perdas após a fritura, os parâmetros elasticidade e coesividade e a avaliação sensorial não foram encontradas diferenças (p>0,05) entre as formulações. A aplicação de fibra de ervilha e redução de carne e gordura nos hambúrgueres não afetaram (p>0,05) os valor de pH, parâmetros de cor L* e b*, os parâmetros avaliados no perfil de textura, perdas de peso por cocção, redução do tamanho (encolhimento) e avaliação sensorial, apenas a formulação HFMC apresentou redução (p<0,05) no parâmetro a*. Quanto ao apresuntado, os parâmetros de dureza e mastigabilidade foram maiores (p<0,05) para a formulação AC, a formulação AFMC apresentou valor de L* superior (p<0,05), parâmetros de cor a* e b* inferiores (p<0,05) ao C e maior aceitação geral, já o valores de pH, perdas por gotejamento e as médias dos demais atributos sensoriais avaliados não apresentaram diferença (p>0,05) entre as formulações. Em relação aos resultados obtidos na salsicha, a formulação SFMG apresentou pH inferior (p<0,05) a SC e maior valor para os parâmetros de dureza e mastigabilidade. As formulações SFMC e SFMG apresentaram rendimento inferior (p<0,05) a SC e não diferiram quanto à estabilidade da emulsão, já em relação a avaliação sensorial formulação SFMC apresentou notas superiores (p<0,05) à formulação SC e SFMG quanto aos atributos textura, sabor e aceitabilidade geral. De acordo com os resultados obtidos pode-se concluir que a fibra de ervilha mostrou-se como um ingrediente promissor para aplicação em produtos cárneos, já que nas condições testadas a substituição parcial de carne e gordura por fibra de ervilha não ocasionou prejuízo na maioria dos parâmetros físico-químicos avaliados e não prejudicou a aceitação sensorial em nenhum dos produtos cárneos estudados. / The objective of this study was to characterize physicochemical aspects of meat products and their sensorial acceptance elaborated with the addition of pea fiber as a partial substitute of meat (aiming the product cost reduction), and fat (aiming a healthier product). Four different meat products were formulated and processed (chicken nuggets, burger, chopped ham and frankfurter), as follows: chicken nuggets (Nuggets Control (NC) - formulation similar to the commercial product, Nuggets Fiber Less Meat (NFLM) - 10% of meat reduction and 2% of pea fiber addition, and Nuggets Fiber Less Fat (NFLF) - 10% of fat reduction, and 2% of pea fiber addition), burger (Burger Control (HC) - similar to the commercial formulation; Burger Fiber Less Meat (BFLM) - 5% of meat reduction, and 1% of pea fiber addition, and Burger Fiber Less Fat (BFLF) - 7% of fat reduction, and 1% of pea fiber addition); chopped ham (Chopped Ham Control (CHC) - similar to the commercial formulation, and Chopped Ham Fiber Less Meat (CHFLM) - 5% of meat reduction, and 1% of pea fiber addition), chopped ham (Chopped Ham Control (CHC) - similar to the commercial formulation, and Chopped Ham Fiber Less Meat (CHFLM) - 5% of meat reduction, and 1% of pea fiber addition), and frankfurter: ( Frankfurter Control (FC) - similar to the commercial formulation; frankfurter Fiber Less Meat (FFLM): 5% of beef reduction, and 2% pea fiber addition, and Frankfurter Fiber Less Fat (FFLF) - 7% of fat reduction, and 1% of pea fiber addition). After processing the products were characterized concerning proximal composition, color determination, texture, weight loss after frying (chicken nuggets), weight loss after cooking (burger), diameter reduction (burger), drip loss (chopped ham), product outcome (frankfurter), emulsion stability (frankfurter) and sensory analysis (nine point hedonic scale acceptance test). For the nuggets NFLM and NFLF formulations presented higher levels of pH (p<0.05) compared to control, and NFLF formulation presented higher (p<0.05) firmness. Regarding the losses after frying, the elasticity parameters, and cohesiveness and sensory analysis were not different (p>0.05) among formulations. The pea fiber addition and meat and fat reduction in burgers did not affect (p>0.05) the pH levels, color parameters L* and b*; the analyzed parameters concerning texture, weight loss after cooking, diameter reduction (shrinking), and sensory analysis, only BFLM formulation presented reduction (p<0.05) in the parameter a*. Regarding the chopped ham, firmness and chewiness parameters were higher (p<0.05) compared to CHC formulation, CHFLM formulation presented higher L* levels (p<0.05), lower parameters of color a* and b* (p<0.05) compared to CHC and higher general acceptance, yet the pH levels, drip loss and the averages of the other sensory characteristics analyzed did not present difference (p>0.05) among formulations. Regarding the results obtained with the frankfurter, the FFLF formulation presented lower pH levels (p<0.05) compared to FC and higher values for firmness and chewiness parameters, FFLM and FFLF formulations presented lower outcome (p<0.05) compared to FC and were not different to the emulsion stability, however regarding the sensory analysis FFLM formulation presented higher values (p<0.05) compared to FC and FFLF concerning texture, flavor and general acceptance. According to the results it is concluded that pea fiber is a promising ingredient to be added in meat products, since the tested conditions in the partial substitution of meat and fat for pea fiber did not cause significant change in most analyzed physicochemical parameters and did not interfere the sensory acceptance in any of the studied meat products.

This paper considers the way Herbert Marcuse’s re-formulation of the instrumental reason as a technical reason can be understood as an intensification or acceleration of some of the themes presented by Theodor W. Adorno and Max Horkheimer in The Dialectics of Enlightenment. By reading Marcuse´s The One-Dimensional Man in dialogue with Martin Heidegger’s The Question Concerning Technology, the paper explores a thesis that Marcuse draws on concepts from Heidegger, especially Ge-stell and Bestand, in his notion of the “technical reason” and “technological rationality” to think and think beyond modern technology. By positing modern technology as the focal point of the instrumentalization of reason, Marcuse sheds light of historical and contemporary problems with human thinking. The staging of this conversation with Marcuse and Heidegger that never really took place allows the paper to fully explore and understand Marcuse’s invoking of the aesthetical dimension, as well as his re-appropriation of Freudian terminology, as a model to re-establish negative thinking as a necessary counteraction to the one-dimensional positive thinking that is dominating private and public sphere.

La tesi si inserisce nella discussione intorno al quadro del sistema politico italiano in Germania e analizza le modalità secondo le quali viene trattata la politica italiana nella stampa tedesca “di qualità” nel periodo della cosiddetta “Seconda Repubblica”. Oltre a presentare l’immagine delle istituzioni, dei partiti e dei candidati alle elezioni politiche nei media tedeschi, il lavoro illustra l’origine della percezione e i processi comunicativi che riducono la complessità della realtà nella cronaca politica estera basandosi sulle teorie di gatekeeping, news bias, news values e framing. L’analisi del lavoro quotidiano dei comunicatori mediali (ca. 90 interviste e questionari) e la content analysis di 1.024 articoli mostrano che il quadro del sistema politico italiano nella stampa tedesca non si caratterizza tanto per una valutazione negativa della politica italiana tout court, quanto piuttosto per una forte personalizzazione – con valutazioni costantemente aggiornate – intorno alle figure dei leader politici. La tesi dimostra infine come, diversamente da quanto avviene per le questioni di politica interna, l’orientamento politico delle testate non condizioni fortemente la cronaca politica estera, bensì come ai corrispondenti venga lasciata estrema libertà nella mediazione culturale tra Italia e Germania e nella valutazione dei fatti e personaggi che compongono il complesso panorama politico italiano. / In the ongoing discourse about Italy's political image in Germany, the dissertation adds to the discussion the analysis of the modalities about how the present-day image of Italy's political system is handled in the German media during the so-called “Second Republic”. More than the illustration of Italy´s political institutions, parties and leader images in German media, the paper consults theories of gatekeeping, news bias, news values, and framing handles with the origins of the perception and in particular with the communication processes that reduce the accuracy in political foreign news. The analysis of journalist's daily work through 90 interviews / questionnaires and a content analysis of 1.024 newspaper articles shows that the media image of Italy's political system is not so much characterized as permanently negative as it is a never-ending personalization of Italy's political leaders. Finally, the dissertation shows the political orientation of newspapers in contrast to national news doesn't significantly influence foreign news. Moreover it was demonstrated the processes of perception and communication that take place in foreign news is determinant. Under these restrictions the correspondents are able to use the scope of development for writing articles and judging the events and the characters of Italy's political system.

Anhand einer Analyse von deutschen Zeitungsartikeln, welche sich jeweils mit den Themen Brust- oder Lungenkrebs beschäftigen, wird in dieser Dissertation die Bedeutung von Prävention herausgearbeitet. Im Fokus der Fragestellung steht hierbei, wie sehr die Gesamtberichterstattung beider Krankheiten durch das Thema Prävention beeinflusst wird, ob ihre Prävention vorwiegend als positiv oder kritisch bewertet wird und wie sich die Präventionsschwerpunkte bei Brust- und Lungenkrebs unterscheiden.

The primary focus of this thesis is on representations of Germany and Germans in the sports pages of English newspapers from the mid-1950s to the mid-1990s, when EURO 96 generated press coverage that prompted much comment and criticism, both in England and in Germany. Studies focusing on media representations from the mid 1990s onwards, such as those by Maguire, Poulton and Possamai (1999), Garland and Rowe (1999) and Garland (2004) have been helpful in deconstructing the language used by football journalists and in identifying negative national stereotyping. More recently, however, Ramsden (2007) and Young (2007) have developed our understanding of Anglo-German cultural relations and how they have changed since 1945. In the light of these recent developments this thesis seeks, firstly, to analyse the discourses embedded within the ‘Two World Wars and One World Cup’ meta-narrative which has characterized press coverage of Anglo-German football since international fixtures between the two countries were resumed in 1954 and, secondly, to contextualize them in the broader history of Anglo-German cultural relations and how they developed over the forty years or so that followed. Though drawing on some insights from both cultural and media studies the methodology employed is essential historical. This does not mean, however, that press reports and comment are regarded as unproblematic primary sources. Recent methodological approaches the history of sport, notably by Booth (2005) and Hill (2006), have pointed to the importance of viewing such sources as texts which are thus open to deconstruction. A complementary emphasis on historical context is nevertheless justified, principally because it is important to explain variations that have occurred over time. Though there were some similarities in the way that Anglo-German football was covered in 1954 and 1996 – and at various points in between - there are also striking differences which it is argued here are primarily explained by conditions prevailing at the particular historical junctures at which representations were generated. The relationship which existed between Britain and the Federal Republic of Germany (West Germany) in the 1950s, 1960s and 1970s was significantly different to that which existed between Britain and re-unified Germany in the 1990s. This was an important contingent factor and helps to explain variations in the deployment of journalistic discourses over the years. Thus this thesis breaks new ground in that it emphasizes the historical contextualization of representations over a long period and seeks to counter any tendency to look backwards from the viewpoint of the mid 1990s. The discussion proceeds chronologically from the 1950s to the 1990s in order to demonstrate variations in the way that discourses were deployed over the years. Thus the representations generated provide a way of reading the state of underlying Anglo-German relations at any given point. One chapter is devoted to the 1966 World Cup Final on account of its significance in press discourses relating to Anglo-German football and in what is popularly referred to in England as the 'thirty/forty years of hurt' that followed. Whereas academic attention in relation to football-related representations has previously concentrated on the downmarket tabloid press, this study is equally concerned with quality and middlemarket titles. Thus The Times and the Daily Express are considered alongside the Daily Mirror and the Sun. Finally – and in contrast to previous accounts which have considered the English press in isolation – a chapter on German newspaper coverage (principally Bild, Die Welt and Frankfurter Allgemeine Zeitung) has been included to allow some comparisons to be made and to point to directions in which future research might be pursued.

(in English) This diploma thesis focuses on the Book World Prague - International Book Fair and Literary Festival - in the context of the transformation of the Czech book market after 1989. Particularly, it aims to examine the role the Book World Prague played in rehabilitation of the Czech book market as for re-implementation of basic market mechanisms in book production and distribution. Individual chapters cover the following topics: characterization and typology of modern book fairs, the history of the Czech book market from 1948 the present day, the history of the origin of trade fairs, the specific history and developments of book fairs, and the milestones in the history of the Book World Prague. Central to the research are data collected by the author by interviewing ten professionals working in various fields of the book industry. The transcribed interviews served two major purposes: firstly, they were used as the primary source enabling the author to answer the research question. Secondly, they created a primary source material relating the history of the Book World Prague.
