Given the explicit focus of compulsory schooling in Sweden on providing pupils with opportunities to develop their communicative abilities, all available resources should be utilised to their fullest potential - one of these resources being the way a teacher talks to and with their pupils, i.e., their teacher talk. Previous research in the field has had its focus on non-Swedish classroom contexts and has primarily considered the impacts of teacher talk on learners in secondary school or above. This study therefore set out to contribute to the field by observing Swedish EFL lessons for grades 4-6 and interviewing the teachers of these lessons. The observations show that different teacher-talk categories were employed at varied frequencies, some noticeably more widely represented than others. Additionally, valuable insight was gained from the interviews into teachers’ reflections on their didactic choices made regarding teacher talk. Some of the teachers’ choices correlated with those found in previous research, such as the rationale for direct translations from L2 to L1. On the other hand, it emerged that teachers perceived that some teacher-talk categories were utilised more in the higher grades, in contrast with the results noted in the observations of this study. This could suggest that teachers were not utilising all available resources effectively and possibly could benefit from further support and/or training in how to use their teacher talk consciously. To comprehensively evaluate which, to what extent, and why different teacher-talk categories are represented, further research should focus on a prolonged engagement in longitudinal studies of Swedish EFL classrooms representing a greater variety and number of schools as well as participating teachers.

[pt] Os desafios de estudar formas levaram matemáticos a criar abstrações, em particular através da geometria diferencial. Porém, formas simples como cubos não se adequam a ferramentas diferenciáveis. Este trabalho é uma tentativa de usar avanços recentes da análise, no caso a teoria das distribuições, para estender quantidades diferenciáveis a objetos singulares. Como as distribuições generalizam as funções e permitem derivações infinitas, substituição das parametrizações de subvariedades clássicas por distribuições poderia naturalmente generalizar as subvariedades suaves. Isso nos leva a definir D-imersões. Esse trabalho demonstra que essa formulação, de fato, generaliza as imersões suaves. Extensões para outras classes de subvariedades são discutidas através de exemplos e casos particulares. / [en] The challenge of studying shapes has led mathematicians to create powerful abstract concepts, in particular through Differential Geometry. However, differential tools do not apply to simple shapes like cubes. This work is an attempt to use modern advances of the Analysis, namely Distribution Theory, to extend differential quantities to singular objects. Distributions generalize functions, while allowing infinite differentiation. The substitution of classical immersions, which usually serve as submanifold parameterizations, by distributions might thus naturally generalize smooth immersion. This leads to the concept of D-immersion. This work proves that this formulation actually generalizes smooth immersions. Extensions to non-smooth of immersions are discussed through examples and specific cases.

The thesis deals with a musical aspect in Czech films directed by Miloš Forman. The topic is investigated within a wider context of musical culture of the 1960s as it is focused on analysis of cultural phenomena associated with musical expression which left their impression on Forman's films and participated, to great extent, in specificity of their soundtracks. So the films are not analyzed as separate artifacts, but they are considered as documents affected by the social climate at that time. Common social phenomena which were an integral part of Forman's films are studied such as dancing parties, twist and radio broadcasting. The Forman's cooperation with the Semafor theatre is analyzed as well as how Semafor poetics influenced his films. Jiří Suchý's lyrics and the period hits classified as the medium pop music stream are carefully analyzed as they are an important part of Forman's films. A short outline of the cinematographic context of the 1960s and comparison with films thematically similar help to specify Forman's approach to the music aspect. The collage-like structure of the work highlights a few contradictory trends in pop music of the 1960s whose variety can be seen in Forman's films.

The problem of this thesis is to describe, classify, and analyze the formal responses that the white Christian churches made to Mr. Forman and the Black Manifesto. Such a problem encompasses a consideration of the following questions: What responses did the church give? What patterns developed within the responses? Why did the churches respond in the manner they did?

[pt] A geometria diferencial descreve de maneira intuitiva os objetos suaves no espaço. Porém, com a evolução da modelagem geométrica por computador, essa ferramenta se tornou ao mesmo tempo necessária e difícil de se descrever no mundo discreto. A teoria de Morse ficou importante pela ligação que ela cria entre a topologia e a geometria diferenciais. Partindo de um ponto de vista mais combinatório, a teoria de Morse discreta de Forman liga de forma rigorosa os objetos discretos à topologia deles, abrindo essa teoria para estruturas discretas. Este trabalho propõe uma definição construtiva de funções de Morse geométricas no mundo discreto e do complexo de Morse-Smale correspondente, onde a geometria é definida como a amostragem de uma função suave nos vértices da estrutura discreta. Essa construção precisa de cálculos de homologia que se tornaram por si só uma melhoria significativa dos métodos existentes. A decomposição de Morse- Smale resultante pode ser eficientemente computada e usada para aplicações de cálculo da persistência, geração de grafos de Reeb, remoção de ruído e mais. . . / [en] Differential geometry provides an intuitive way of understanding smooth objects in the space. However, with the evolution of geometric modeling by computer, this tool became both necessary and difficult to transpose to the discrete setting. The power of Morse theory relies on the link it created between differential topology and geometry. Starting from a combinatorial point of view, Forman´s discrete Morse theory relates rigorously discrete objects to their topology, opening Morse theory to discrete structures. This work proposes a constructive definition of geometric discrete Morse functions and their corresponding discrete Morse-Smale complexes, where the geometry is defined as a smooth function sampled on the vertices of the discrete structure. This construction required some homology computations that turned out to be a significant improvement over existing methods by itself. The resulting Morse-Smale decomposition can then be efficiently computed, and used for applications to persistence computation, Reeb graph generation, noise removal. . .

This master's thesis is devoted to the changes of Miloš Forman's media image, more precisely how period press noticed both his career and work. Miloš Forman is the most acknowledged and most famous czech film director. His story is connected with story of czech cinematography and story of its changes. The thesis wants to find out, why Forman wasn't destroyed even though he left the country, despite his emigration. It is trying to prove that his media image never been strictly negative and Forman itself never became taboo. Forman's person is beyond all standards. He is proof, that if the work is not strong crtitical against regime, it arouses respect despite all the ideology. He was reflected in the various stages, but still in relatively good light. The thesis examines the perception of the media in three life stages: work in Czechoslovakia before going to the United States, working abroad and finally after the Velvet Revolution. Although Forman has participated in many films, thesis focused only on his feature-length work. And because Miloš Forman is a person who transcends the borders of Czechoslovakia, or the Czech Republic, media abroad reflected his career as well, althought the view there was slightly different from the domestic one.
