Este trabalho se propõe a elaborar uma tradução comentada de um tratado médico de Paracelso, importante ator na individualização de diversas áreas modernas de conhecimento a partir da Alquimia. A imagem geralmente associada a ele se mostra marcada pelas campanhas difamatórias havidas que, provavelmente, facilitaram que a influência de suas ideias fosse progressivamente diminuída e posta de lado. Especificamente na esfera da língua portuguesa, a disponibilidade de textos seus é limitada, sendo, essencialmente, restrita a algumas (poucas) traduções indiretas. O corpus para a tradução propriamente dita compõe-se de três versões, num corte diacrônico, do tratado Von den ersten drei Essentiis: a edição de 1589, pouco após a morte de Paracelso, a edição de 1930, ainda em Frakturschrift e muito parecida com a de 1589, e a edição de 1965, apresentada já em alemão moderno e em fonte Antiqua. No cotejo destas edições observaram-se diferenças sugestivas da existência de propostas (escopos) individuais para cada edição. A primeira como texto técnico, a segunda como texto de divulgação, de cunho histórico, e a terceira, de cunho também histórico, mas voltada para o público moderno. Para a chamada Skopostheorie, o escopo ocupa posição central numa tradução e em seu redor, e diretamente condicionadas por ele, gravitam todas as decisões tradutórias. Por esta valorização dada ao escopo, que, para este trabalho, foi diverso daqueles apresentados no corpus, optou-se pela Skopostheorie como balizamento teórico dos trabalhos. Assim, o escopo regeu a definição das soluções propostas para os diversos desafios de tradução encontrados. Dentre eles estão as mudanças linguísticas decorrentes da passagem do tempo, a presença de elementos do latim no texto-fonte (na forma de palavras e presença de declinação) e os variados recursos que Paracelso empregou para contornar limitações linguísticas impostas pelo Frühneuhochdeutsch (tais como neologismos e germanizações, com diferentes graus de preservação e incorporação efetiva no alemão moderno). / This paper proposes to elaborate a commented translation, from German to Portuguese, of a medical treatise of Paracelsus, an important actor in the individualization of several modern areas of knowledge from Alchemy. The image usually associated with him is strongly influenced by defamatory campaigns moved against him by his contemporary peers and that have made it easier for the influence of his ideas to be progressively diminished and set aside. Specifically in the sphere of the Portuguese language, the availability of his texts is limited, being essentially restricted to (a few) indirect translations. The corpus for the translation itself consists of three versions, in a diachronic section, of the treatise Von den ersten drei Essentiis: the 1589 edition, shortly after the authors death, the 1930 edition, still in Fraktur type font and very much like the one of 1589, and the edition of 1965, already presented in modern German and Antiqua font. In the comparison of these editions, were found differences suggestive of the existence of individual purposes (scopes) for each edition. The first one as a technical text, the second as a text of divulgation, of a historical nature, and the third, also historical, but aimed at the modern public. Within the chosen theoretical framework, known as Skopostheorie, the scope occupies a central position in a translation and around it, and directly conditioned by it, gravitate all the translation decisions. This importance attached to scope was decisive as the scope for this work, was different from the others presented in the corpus. Thus, the scope governed the definition of the solutions proposed for the various translation challenges encountered. Among them are linguistic changes deriving from the passage of time, the presence of Latin elements in the source text (in the form of words and presence of declination) and the varied resources that Paracelsus used to circumvent language limitations imposed by the Frühneuhochdeutsch (such as neologisms and germanizations, with different degrees of preservation and effective incorporation into modern German).

Die zuverlässige Berechnung der elektrischen Leitfähigkeit vieler Materialien aus ersten Prinzipien erfordert die Berücksichtigung der anharmonischen Gitterdynamik. Der ab initio Kubo-Greenwood (KG)-Ansatz, der die KG-Leitfähigkeitsformel und die ab initio-Molekulardynamik kombiniert, scheint vielversprechend zu sein, da er die Anharmonizität des Gitters auf natürliche Weise berücksichtigt. Seine Anwendung auf kristalline Materialien hat jedoch bisher nur wenig Beachtung gefunden. Diese Arbeit beschreibt den KG-Ansatz und stellt eine numerische Implementierung dieses Ansatzes für den harmonischen Kristall Si und den anharmonischen Kristall SnSe vor. Die Fallstudie für Si zeigt erhebliche numerische Schwierigkeiten bei den KG-Berechnungen auf. Insbesondere behindert die erforderliche dichte k-Punkt-Abtastung die Konvergenz in Superzellengröße und macht die Berechnungen nur innerhalb der (semi-)lokalen Dichtefunktionaltheorie (DFT) durchführbar. Außerdem führt die notwendige Einführung eines Verbreiterungsparameters (η) zu einer erheblichen Unsicherheit bei der Bestimmung der Leitfähigkeit. Um diese Probleme zu lösen, werden rechnerisch effiziente Strategien diskutiert, darunter: (i) der "Scherenoperator"-Ansatz zur Korrektur des DFT-Bandlückenproblems; (ii) das "Optimal-η-Schema" zur Wahl eines geeigneten Wertes von η; und (iii) die Finite-Size-Scaling-Methode zur Ableitung der Leitfähigkeit in der thermodynamischen Grenze. Es wird festgestellt, dass die KG-Berechnungen mit diesen Strategien Leitfähigkeiten in angemessener Übereinstimmung mit den Experimenten ergeben. Der Vergleich mit früheren ab initio Boltzmann-Transportberechnungen zeigt jedoch, dass das η-Problem und die Frage der Konvergenz in Superzellengröße weiter verbesserte Konzepte erfordern. Die Fallstudie für SnSe zeigt sehr ähnliche numerische Schwierigkeiten wie im Fall von Si. Es werden Einblicke in die Auswirkung der Anharmonizität auf die Konvergenz der Superzellengröße gegeben. / Reliable first-principles calculation of the electrical conductivity in many materials requires accounting for the anharmonic lattice dynamics. The ab initio Kubo-Greenwood (KG) approach, which combines the KG conductivity formula and ab initio molecular dynamics, appears to be promising because it naturally includes lattice anharmonicity. However, its application to crystalline materials has so far received very little attention. This thesis describes the KG approach and presents a numerical implementation of this approach for the harmonic crystal Si and the anharmonic crystal SnSe. The case study for Si identifies considerable numerical difficulties in the KG calculations. In particular, the dense k-point sampling required hinders supercell-size convergence and makes the calculations only feasible within (semi)local density-functional theory (DFT). Besides, the necessary introduction of a broadening parameter (η) introduces a significant uncertainty in determining the conductivity. To address these issues, computationally efficient strategies are discussed, including: (i) the "scissor operator" approach to correct the DFT band-gap problem; (ii) the "optimal-η scheme" to choose an appropriate value of η; and (iii) the finite-size scaling method to deduce the conductivity in the thermodynamic limit. It is found that with these strategies, the KG calculations yield conductivities in reasonable agreement with experiment. Yet, comparison with previous ab initio Boltzmann transport calculations shows that the η problem and the issue of supercell-size convergence still require improved concepts. The case study for SnSe shows very similar numerical difficulties as in the case of Si. Insights into the effect of anharmonicity on the supercell-size convergence are provided.

The central notion of this thesis is the minor relation on functions of several arguments. A function f: A^n→B is called a minor of another function g: A^m→B if f can be obtained from g by permutation of arguments, identification of arguments, and introduction of inessential arguments. We first provide some general background and context to this work by presenting a brief survey of basic facts and results concerning different aspects of the minor relation, placing some emphasis on the author’s contributions to the field. The notions of functions of several arguments and minors give immediately rise to the following reconstruction problem: Is a function f: A^n→B uniquely determined, up to permutation of arguments, by its identification minors, i.e., the minors obtained by identifying a pair of arguments? We review known results – both positive and negative – about the reconstructibility of functions from identification minors, and we outline the main ideas of the proofs, which often amount to formulating and solving reconstruction problems for other kinds of mathematical objects. We then turn our attention to functions determined by the order of first occurrence, and we are interested in the reconstructibility of such functions. One of the main results of this thesis states that the class of functions determined by the order of first occurrence is weakly reconstructible. Some reconstructible subclasses are identified; in particular, pseudo-Boolean functions determined by the order of first occurrence are reconstructible. As our main tool, we introduce the notion of minor of permutation. This is a quotient-like construction for permutations that parallels minors of functions and has some similarities to permutation patterns. We develop the theory of minors of permutations, focusing on Galois connections induced by the minor relation and on the interplay between permutation groups and minors of permutations. Our results will then find applications in the analysis of the reconstruction problem of functions determined by the order of first occurrence.

Diese Arbeit untersucht die Konstruktion von Autoridentitäten am Beispiel eines Korpus aus 25 deutschen und 25 US-amerikanischen wissenschaftlichen Artikeln aus dem Fach Soziologie, die in den beiden führenden Fachzeitschriften der Länder veröffentlicht wurden. Am Gebrauch der ersten Pronomen der Person in Kombination mit den ihnen zugeordneten Verben wird nachgezeichnet und verglichen, welche Rollen sich die deutschen und US-amerikanischen Autoren in ihren Texten zuschreiben. Dabei werden sowohl quantitativ als auch qualitativ weitreichende Unterschiede deutlich, die auf grundlegend unterschiedliche Konventionen, wie in den beiden Wissenschaftskulturen wissenschaftliche glaubwürdige Autorenidentitäten konstruiert werden, hindeuten. Weitergehend wird an einer Fallstudie gezeigt, dass diese Konventionen zwar nachweisbar, aber dennoch nicht notwendigerweise bindend sind, da erfahrene Autoren dennoch in der Lage sind, eine glaubwürdige Autorenidentität zu konstruieren, auch wenn sie umfassend gegen diese Konventionen verstoßen. Dies wird anhand einer Fallstudie belegt. Weitergehend werden die Ergebnisse im Rahmen des Impression Managements in einem sozialpsychologischen Kontext betrachtet und abschließend in ihrem Nutzen für die Schreibdidaktik diskutiert.
