The last one hundred years of American literature have witnessed the development of three elemental movements: naturalism, in the late nineteenth and early twentieth centuries, represented by such authors as Stephen Crane and Theodore Dreiser; nihilism, predominant in the 1920's and 1930's, represented best by Ernest Hemmingway; and the post-World War II literature which will be called literature of the quest, represented by such authors as Saul Bellow, William Styron, Philip Roth, John Updike, and others. The first chapter will show briefly the historical development of these three movements in American literature, their distinctive features, and their relationship to American moral and social values. Chapters Two through Four will analyze in detail the three distinctive aspects of this emerging literary form--the literature of the quest. The last chapter will focus on one novel, Letting Go, by Philip Roth, as an example of this literature.

In this thesis was observed an influence of silvicultural treatment on the structure of young birch stand. On location Stará Ves nad Ondřejnicí was chosen a 10 years old birch stand and on location Hlubočec a 15 years old one. The stands originated spontaneously from natural regeneration on clearing. On both locations were researched two stands in 2015, 2016 and 2017. Within the stands, control variants and the thinning ones were established in 2015. In the case of variants focused on a thinning was executed a repeated intervention in 2016 and in the same time a pruning of a part of individuals in the spring of 2017. On all variants all the woody plants were recorded with a height above 2 metres, which were measured a diameter at breast height (cm) during the years 2015–2017. On intervention variants at marked trees (samplers) were measured a total tree height (cm), an occurrence of a dry treetop (cm) and an occurrence of a live treetop (cm) as well. At the beginning and at the end of 2017 was also measured a treetop projection (cm) at all individuals on the area. Non-interventional stands reported a high number of individuals with a low diameter at breast height in both cases, which represented a significantly low resistence of these stands. This led to a reduction in stability, especially against the snow. Despite a major reduction in the number of individuals in the intervention stands, the proportion of trees was still higher compared to the mentioned literature. In response to this intervention was recorded an increased growth or base. The differences here did not manifest themselves as statistically significant during the first year after the intervention. Based on the results, which showed especially significant differences in the density of the cultivated stand with the non-interventional one can be recommended a very powerful intervention towards the release of the stand and the increase of stability.

Through an examination of Joseph Roth’s reportage and fiction published between 1923 and 1932, this thesis seeks to provide a systematic analysis of a particular aspect of the author’s literary style, namely his use of sharply focused visual representations, which are termed Heuristic Visuals. Close textual analysis, supplemented by insights from reader-response theory, psychology, psycholinguistics and sociology illuminate the function of these visual representations. The thesis also seeks to discover whether there are significant differences and correspondences in the use of visual representations between the reportage and fiction genres. Roth believed that writers should be engagiert, and that the truth could only be arrived at through close observation of reality, not subordinated to theory. The research analyses the techniques by which Roth challenges his readers and encourages them to discover the truth for themselves. Three basic variants of Heuristic Visuals are identified, and their use in different contexts, including that of dialectical presentations, is explored. There is evidence of the use of different variants of Heuristic Visuals according to the respective rhetorical demands of particular thematic issues. It has also been possible to establish synchronic correspondences between the different genres, and diachronic correspondences within genres. Although there are examples within the reportage where the entire article is based on an Heuristic Visual, the use of Heuristic Visuals cannot be seen as a key organizing principle in Roth’s work as a whole. As his mastery of the technique reaches its highest point in the early 1930s, Heuristic Visuals are often incorporated into the reconstruction of a complete sensory experience. Analysis of Roth’s heuristic use of visual representations has led to important insights, including a reinterpretation of the endings of Roth’s two most famous novels: Hiob and Radetzkymarsch.

Neste trabalho estudamos o célebre Teorema de Klaus F. Roth para aproximações diofantinas, também conhecido como Teorema de Thue-Siegel-Roth. Nossos objetivos consistem em fazer um estudo abrangente da evolução do problema, que se iniciou com um resultado de Liouville em 1844, e chegar à completa compreensão das ideias e das técnicas utilizadas na demonstração do Teorema de Roth. / In this work we study the celebrated Klaus F. Roth\'s Theorem in Diophantine approximations, also known as the Thue-Siegel-Roth Theorem. Our goals are to make a comprehensive study of the evolution of the problem that started with a result of Liouville in 1844 and achieve full understanding of ideas and techniques used in the proof of the Roth\'s Theorem.

Este tese aborda a obra do escritor judeu austríaco Joseph Roth, buscando entender a crítica que ele faz à modernidade como resultante de um ponto de vista singular, determinado pelo encontro entre dois mundos: o mundo do tradicionalismo judaico no Leste europeu e o mundo da monarquia habsburga, em seus anos finais. Pretende-se demonstrar que é tomando como referência os parâmetros destes dois universos que Roth dirige um olhar cético para a modernidade e para o mundo pós-1ª. Guerra Mundial. Ao mesmo tempo, pretende-se demonstrar como o conceito de exílio está inextricavelmente ligado a uma obra crítica com relação a seu tempo, embasada na memória de dois mundos em extinção. Trata-se, porém, de um exílio que se configura mais como a expulsão de um tempo do que como uma simples expulsão geográfica - o que o torna, de certa maneira, mais trágico. O exílio é também uma das categorias centrais da reflexão mística e filosófica judaica, e neste sentido busco apontar para as coincidências entre o tema do exílio em Roth e nas doutrinas desta tradição. Ao conceito de exílio corresponde, como seu duplo e seu oposto, o conceito de Heimat (terra-mãe), que em Roth se torna uma categoria abstrata, pertencente ao universo da metafísica e da memória, e ,como tal, objeto de culto e paradigma, à luz dos quais ele interpreta a realidade do universo europeu entre-guerras. Diante do que foi discutido sobre os temas acima, conclui-se que esta Heimat imaginária afigura-se como uma das suas obsessões literárias, em torno da qual ele construirá uma obra que é, sobretudo, a tentativa de restauração de uma paisagem humana desaparecida e um retrato profundamente nostálgico da memória de uma civilização, ancorada na Idade Média, e sepultada pelo tempo e pelas guerras. / This thesis discusses the oeuvre of the Jewish Austrian writer Joseph Roth, and aims at an understanding of his critique of modernity, which is seen as a result of a unique point of view, determined by the encounter between two worlds: the traditional world of Eastern European Jewry on one hand and the world of the final years of the Habsburg Monarchy on the other. I try to show that Roth takes a skeptical look at modernity and at post-World War I Europe using the paradigms of these two lost worlds.At the same time I aim at demonstrating how the concept of exile is deeply rooted in his critique of modernity. However he is dealing with an exile in time here, as opposed to a purely geographical exile - an exile that is far more tragic, since it is irreversible. Exile is also a core theme in traditional Jewish mystical and philosophical thought and I try to point to coincidences in the treatment of this topic in Roth and in traditional Jewish doctrines.The concept of exile has the idea of Heimat or homeland as its opposite, and in Roth Heimat becomes an abstract category, pertaining to the universe of metaphysics and memory, in the light of which he interprets European civilization of the 1920´s and 1930´s.I conclude by showing how this fictive Heimat turns into one of his literary obsessions, around which he will build an oeuvre, which is, more then anything else, an attempt at restoring a vanished human landscape, anchored in the Middle Ages and buried by time and by wars.
