Introdução: O desenvolvimento psicossexual humano inicia no período pré-natal e é composto pelo papel de gênero (PG), pela identidade de gênero (IG) e pela orientação sexual (OS). Em indivíduos com DDS 46,XY, vários fatores podem comprometer esse desenvolvimento, levando a incongruência de identidade de gênero e à mudança de gênero. Nesses pacientes, a exposição androgênica pré-natal e o grau de virilização da genitália externa tem sido avaliados como possíveis influenciadores destes desfechos, mas seu papel ainda não foi esclarecido. Objetivos: Avaliar os desfechos psicossexuais - IG, PG e OS - e aspectos da vida sexual em uma coorte de indivíduos com DDS 46,XY na idade adulta com diagnostico etiológico caracterizado do ponto de vista clínico e molecular e investigar a influência da exposição androgênica pré-natal e do grau de virilização da genitália externa nesses desfechos e na prevalência de disforia de gênero (DG). Pacientes: 144 pacientes com diagnóstico etiológico confirmado de DDS 46,XY acompanhados do HCFMUSP com idade entre 16 e 60 anos foram incluídos neste estudo. Métodos: Os componentes do desenvolvimento psicossexual (IG, PG, OS) foram avaliados usando questionários e por teste psicológico projetivo (HTP - House-Tree-Person). O escore de Sinnecker foi utilizado para a mensuração do grau de virilização da genitália externa. A exposição androgênica pré-natal foi estimada de acordo com a etiologia do DDS 46,XY. Aspectos da vida sexual foram avaliados através de questionário específico.Todas as variáveis categóricas foram analisadas usando teste X². A força de associação foi avaliada pelo cálculo do V de Cramer. O índice kappa foi usado para avaliar concordância entre resultados dos testes. Resultados: Houve uma associação positiva entre exposição androgênica pré-natal e a maior incidência de desfechos psicossexuais masculinos em indivíduos com maior exposição. O grau de virilização da genitália externa não interferiu nos desfechos psicossexuais. Houve uma prevalência de 19% (27/144) de disforia de gênero em toda a coorte. Em 93% (25/27), a DG foi do sexo feminino para o masculino e ocorreu em 50% (16/32) de casos de deficiência de 5alfa-RD2, seguido de 33% (5/15) dos casos de deficiência da 17beta-HSD3 e se associou com exposição androgênica pré-natal (p < 001; V=0,461), mas não com a virilização da genitália externa. A mediana de idade do desejo de mudar de sexo foi de 8 anos (5 - 9) enquanto que a da idade da mudança de sexo foi 15 anos (10.5 - 20). Os desfechos psicossexuais mostraram maior concordância com o sexo social final (PG - k=0.81; IG - k=0.65 e OS - k=0.85) do que com o sexo de registro (PG - k=0.1; IG - k=0.25 e OS - k=0.15). Quanto a sexualidade, alguns parâmetros (fantasias sexuais, masturbação e parceiro sexual fixo) foram melhores no sexo masculino comparado ao feminino. No entanto, não houveram diferenças em relação aos parâmetros da vida sexual comparando indivíduos do sexo feminino com e sem atipia genital e indivíduos do sexo masculino que mantiveram o sexo social com os que mudaram para este sexo. Conclusões: A exposição androgênica pré-natal influenciou o desenvolvimento psicossexual em indivíduos com DDS 46,XY, de uma forma exposição-dependente, favorecendo desfechos masculinos, enquanto que o grau de virilização da genitália externa não influenciou estes desfechos. A DG do feminino para o masculino foi comum entre esses indivíduos e também foi influenciada pela exposição androgênica pré-natal. Os parâmetros psicossexuais nesses pacientes concorda muito mais com o sexo social final do que com o sexo de registro. A sexualidade dos indivíduos do sexo masculino tem aspectos mais satisfatórios que o feminino. Atipia genital no sexo feminino não afetou a sexualidade destas pacientes assim a sexualidade dos indivíduos que mudaram para o sexo masculino são semelhantes aos que foram registrados no sexo masculino Behavioral and Psychosexual Aspects of 46,XY DSD Individuals At Adulthood / Introduction: The human psychosexual development begins at prenatal period and is composed by gender role, gender identity and sexual orientation. In 46,XY DSD individuals a variety of factors may jeopardize an adequate psychosexual development and sometimes results in desire to change the gender. The effects of prenatal androgen exposure and the impact of atypical genitalia in the psychosexual outcomes have been suggested as influencing factors in the human psychosexual development but there is not conclusive evidence, especially in DDS 46, XY. Methods: We evaluated the psychosexual compounds - gender role (GR) at childhood gender identity (GI) and sexual orientation (SO) in individuals a large cohort of 144 46,XY DSD individuals, 86% of them raised in the female social sex, from a single tertiary medical center. The same psychologist, specialized in DSD, performed the psychosexual evaluation. We used a questionnaire and a projective psychological test (HTP test) to measure the psychosexual compounds. Prenatal androgen exposure was estimated considering the 46,XY etiology. Sinnecker\'s score was used to measure the external genitalia virilization. All ordinal variables were analyzed using Wilcoxon test. Categorical variables were analyzed using X2 test with posterior Cramer\'s V to measure the association strength. The kappa index was calculated as a concordance measure. Results: We found an association between prenatal androgen exposure and major prevalence of male psychosexual outcomes and a higher incidence of female to male gender dysphoria. There was not difference in the psychosexual outcomes according by external genitalia virilization in male and in female individuals. There was an incidence of 19% of gender dysphoria (27 out from 144). In 93% (n=25), the gender change was from female to male (F to M). The ethological diagnosis related with F to M GD were 5alpha-RD2 deficiency (5ARD2) in 16/32 (50%), followed by 5/15 (33%) in 17beta-HSD3 deficiency (17betaHSD3). Others diagnosis related with F to M GD were: partial gonadal dysgenesis (n=3/24; 12%) and 3betaHSD2 (n=1/3; 33%). Both cases of male to female (M to F) GD occurred in partial gonadal dysgenesis (8%; n=2/24). The median of GD age (desire to belong to another gender) was 8 years old (5-9), and the median of gender change itself was 15 years old (10.5 - 20). In F to M GD, gender change was associated with prenatal androgen exposure (p < 001; V=0,461). The psychosexual components showed higher concordance index with final gender (GI - k=0.81; GI - k=0.65 and SO - k=0.85) then with the assigned sex (GI - k=0.1; GI - k=0.25 and SO - k=0.15). Conclusion: Prenatal androgen exposure affects the psychosexual development, favoring more male outcomes. This influence was observed in GI, GR and SO. The degree of external genitalia virilization did not influence the psychosexual development. Female to Male GD is common in 46,XY DSD raised in female social sex, especially in 5ARD2 and 17?HSD3 deficiencies. There is a strong relationship between prenatal androgen exposure and F to M GD. On the other hand, M to F gender change was rare in 46,XY DSD and occurred only in partial gonadal dysgenesis patients

Le rédacteur lucanien termine son évangile par la scène conventionnelle où le Christ ressuscité charge ses témoins d'une mission. Ainsi, le kérygme pascal résume le cœur de l'annonce de la Bonne Nouvelle aux Juifs et à toutes les nations. La forme brève de cette révélation finale est souvent signalée par tous ceux qui désirent comprendre le projet global de Luc. Cependant il est possible d'approfondir le sens de Le 24, 46-48 à la lumière des discours missionnaires du Livre des Actes des Apôtres. Notre hypothèse de recherche consistait à déterminer comment, à l'intérieur des discours missionnaires, Luc reprend et développe le schéma fondamental du kérygme chrétien livré pour la première fois par le Christ, au jour de Pâques. A l'aide des méthodes historico-critiques jointes à la perspective de l'analyse structurelle, nous avons d'abord étudié Le 24, 46-48, en soulignant les interrogations que soulevait cette péricope. Puis, nous avons analysé les discours missionnaires en considérant de quelle manière le rédacteur lucanien répond lui-même à ces questions. Cette recherche a permis de confirmer l'unité entre l'ensemble du troisième évangile et les Actes. L'étude des discours missionnaires a démontré la cohésion et l'amplitude du schéma de la révélation pascale comme base de tout discours chrétien, selon la perspective de Luc.

Appien est l’auteur d’une histoire universelle, l’Histoire romaine, allant de la fondation de Rome jusqu’à l’époque de Trajan. Parmi les livres qui la composent, nous pouvons remarquer la présence d’un Livre Parthique. Bien qu’Appien lui-même manifeste à plusieurs reprises l’intention d’écrire un Livre Parthique, la tradition manuscrite ne nous a transmis qu’un texte très problématique, intitulé Παρθική, qui n’est qu’un centon d’extraits tirés du Livre Syriaque d’Appien et des Vies d’Antoine et de Crassus de Plutarque. Il est évident que la nature de ce texte a engendré un vif débat sur son authenticité. C’est pour trancher la question que notre thèse fournit une nouvelle édition critique du texte de la Παρθική, prenant en compte les études les plus récentes sur la tradition manuscrite de l’Histoire Romaine ; mais surtout elle vise à prendre parti sur la question de l’authenticité de ce texte, en étudiant la méthode historiographique d’Appien et l’usage qu’il fait de ses sources. Compte tenu de cette analyse, nous pouvons conclure que la Παρθική n’accomplit pas ce que l’historien s’était fixé et que son contenu ne correspond pas aux informations qu’il avait déjà à sa disposition. C’est pourquoi il ne paraît pas possible de considérer authentique la Παρθική. / Appian’s principle surviving work, known as Roman History, inspects the events occurred from Rome foundation until the reign of the Emperor Trajan. Among its different books, we can notice the Parthian History. Despite Appian’s intention of writing a Parthian History, the test that reached us – called Παρθική – is made only of excerpts from Appian’s Syrian History and from Plutarch’s Life of Crassus and Life of Antony. It is clear that the characteristics of this test have generated an intense debate on its authenticity. Object of this work is to shed light on this issue, writing a new critical edition of Παρθική, that takes into account the latest studies of the Roman History manuscript tradition. Furthermore, this work has the aim of taking a position on the question of authenticity through a deep study of Appian’s historiographical method and his use of sources. From this analysis it results that Παρθική is not adherent to Appian purposes and its contents does not match with the information he had available. For these reasons it doesn’t seems possible to take the position of the book authenticity.

O objetivo deste estudo foi avaliar a influência da exposição a níveis normais ou reduzidos de testosterona durante a vida intrauterina no desenvolvimento psicológico, social e sexual dos pacientes com DDS 46, XY. Pacientes e métodos: Trata-se de um estudo retrospectivo. Os 53 participantes são pacientes portadores de DSD 46,XY devido a defeitos de produção de testosterona ou deficiência da 5alfa-RD2, todos eles com genitália ambígua que resultou na atribuição do sexo feminino ao nascimento. Os pacientes foram divididos em dois grupos: Grupo 1 (G1) - pacientes com DDS 46, XY, devido a defeito na produção de testosterona, constituído por 29 pacientes, 8 deles com deficiência de 17beta-HSD3, 7 com hipoplasia das células de Leydig, 7 com disgenesia gonadal parcial, 6 com deficiência 17alfa-hidroxilase e 1 com deficiência 3beta-HSD2; Grupo 2 (G2) - constituído por 24 pacientes com deficiência de 5alfa-RD2. Foi utilizado um questionário com 32 perguntas abrangendo aspectos do desenvolvimento psicológico, social e sexual destes pacientes. Resultados: Foi encontrada uma diferença significativa nos seguintes aspectos do desenvolvimento psicológico, social e sexual dos participantes do estudo: maior incidência de masturbação, fantasias eróticas e desejo de ter filhos em pacientes com deficiência da 5alfa-RD2 com sexo social masculino. Nas pacientes com sexo social feminino o desejo de ter filhos foi maior naquelas com DDS 46, XY por defeitos na produção de testosterona do que naquelas com deficiência da 5alfa-RD2 (p < 0,05), enquanto que o desejo de ter filhos foi maior nos homens com deficiência 5alfa-RD2 (p > 0,05). O número de indivíduos casados foi significativamente maior no grupo dos pacientes com DDS 46, XY por defeitos na produção de testosterona do que no grupo dos pacientes com DDS 46, XY por deficiência da 5alfa-RD2 (p = 0,003). Em conclusão, nossos resultados indicam uma possível influência da exposição aos andrógenos durante a vida pré-natal no desenvolvimento psicológico e social, bem como em aspectos da vida sexual dos pacientes adultos com DDS 46, XY / The aim of this study was to evaluate the influence of exposure to normal or reduced levels of testosterone during intra-uterine life in psychological, social, and sexual development of patients with DSD 46, XY. Patients and methods: This is a retrospective study. The 53 participants were patients with DSD 46, XY due to defects in production of testosterone or deficiency of 5alfa-RD2, all of them with ambiguous genitalia and female sex assignment at birth. These patients were divided into two groups: Group 1 (G1) - patients with DSD 46, XY, due to a defect in the production of testosterone, consisting of 29 people, 8 with deficiency of 17beta-HSD3, 7 with Leydig cell hypoplasia, 7 with partial gonadal dysgenesis, 6 with 17alfa-hydroxylase deficiency ,1 with 3beta-HSD2 deficiency, Group 2 (G2) - consisting of 24 patients with deficiency of 5alfa-RD2. We used a questionnaire with 32 questions covering aspects of psychological, social and sexual development of these patients. Results: A significant difference was found in the following aspects of psychological, social and sexual development of these patients: higher incidence of masturbation, erotic fantasies and desire for children in patients with deficiency of 5alfa-RD2 with male social sex. In patients with female social sex, the desire to have children was higher in those with DSD 46, XY by defects in the production of testosterone than in those with deficiency of 5alfa-RD2 (p < 0.05), while the desire to have children in men was higher in those with 5alfa-RD2 (p > 0.05). The number of married individuals was significantly higher in the group of patients with DSD 46, XY by defects in the production of testosterone than in the group of patients with DSD 46, XY by deficiency of 5alfa-RD2 (p = 0.003). In conclusion, our results indicate a possible influence of exposure to androgens during prenatal life in psychological and social development, as well as in aspects of sexual life of adult patients with DSD 46, XY

Die Dissertation vergleicht die Konzeptkunst in New York und den Moskauer Konzeptualismus am Beispiel zwei ihrer zentralen Vertreter: Joseph Kosuth und Ilya Kabakov. Beide haben unter dem Titel "The Corridor of Two Banalities" 1994 gemeinsam eine Installation realisiert. In Kosuth und Kabakov fanden die Zeitgenossen und Nachfolger sowohl ihr Vorbild als auch Gegenbild. In komparatistischer Perspektive werden Probleme diskutiert (z. B. das der (Selbst-)Referentialität), die die Diskussion über konzeptuelle Kunst begleiten, und konzeptuelle Kunst als Scharnier zwischen Moderne und Postmoderne erscheinen lassen. Konzeptkünstler betrachten kunsttheoretische und -historische Überlegungen in demselben Maße als selbstverständlichen Teil ihrer künstlerischen Arbeit, wie Kunst als universelle Kategorie für sie ihre Selbstverständlichkeit verloren hat. Sie setzen sich mit deren Rahmenbedingungen auseinander, die diktieren, was zu einer bestimmten Zeit und an einem bestimmten Ort als Kunst wahrgenommen wird. Die Dissertation konzentriert sich daher auf die Frage, wie Kosuth und Kabakov die (Konzept-)Kunst diesseits und jenseits des Eisernen Vorhangs selbst konzeptualisieren. Unter Einbeziehung der Rezeptionsgeschichte wird untersucht, welche Vorstellung von Autor- und Leserschaft Kosuth und Kabakov entwerfen, vom welchem Werkbegriff sie ausgehen und auf welche sprachphilosophischen Modelle sie sich dabei beziehen. / The thesis compares the Conceptual Art in New York with the Moscow Conceptualism while using the example of two of their greatest representatives: Joseph Kosuth and Ilya Kabakov. Together, they have created an installation entitled "The Corridor of Two Banalities" (1994). For their contemporaries and successors, Kosuth and Kabakov served as models or just the opposite. In a comparatistical perspective the thesis discusses problems (e.g. the (self-)referentiality) which go along with the debate about conceptual art and which let the conceptual art appear as a link between modernism and postmodernism. For conceptual artists, theoretical and historical considerations of art form an evident part of their artistic work to the same degree as art as a universal category has lost its self-evidence for them. They examine its frame conditions which dictate what is being considered as art at a specific time and in a specific place. Hence the thesis focusses on the question about the ways Kosuth and Kabakov conceptualise the (Conceptual) Art on both sides of the Iron Curtain. Taking into account the reception history it examines which concept of author- and readership Kosuth and Kabakov formulate, which definition of artwork they have assumed and which models of philosophy of language they refer to.

Die Dissertation untersucht einen Paradigmenwechsel in der Rezeption der historischen Avantgarde in (medien-)künstlerischen Projekten der 1980er und 1990er Jahre in Ex-Jugoslawien und Russland. Dieser Paradigmenwechsel liegt im veränderten Verhältnis zum Begriff der (politischen wie künstlerischen) Utopie begründet. In den 1980er Jahren zeichnet sich die Rezeption sowohl im sogenannten sowjetischen Postutopismus (Il’ja Kabakov, Ėrik Bulatov, Oleg Vasil’ev, Komar & Melamid, Kollektive Aktionen) als auch in der jugoslawischen Retroavantgarde (NSK, Mladen Stilinović, Malevič aus Belgrad etc.) durch ein ‚diskursarchäologisches’ Interesse an potentiell totalitären Elementen der Avantgarde aus. Seit Beginn der 1990er Jahre lässt sich eine signifikant veränderte Rezeption der historischen künstlerischen Avantgarde in Projekten junger KünstlerInnen aus dem östlichen Europa festellen (Neoutopismus, Retroutopismus). Die Utopien der Avantgarde werden im sogenannten Retroutopismus (Marko Peljhan, Vadim Fishkin) nicht mehr primär mit totalitären Tendenzen gleichgesetzt, sondern sie werden jetzt vor allem auf ihre medientechnologischen Projektionen und Entwürfe durchgesehen. Diese wurden nicht nur von einzelnen Avantgarde-Künstlern und –Theoretikern (Velimir Chlebnikov, Bertolt Brecht), sondern auch von Wissenschaftlern und Ingenieuren (Nikola Tesla, Herman Potočnik Noordung) am Anfang des 20. Jahrhunderts entwickelt. In den 1990er Jahren wird in künstlerischen Projekten somit ein verstärktes medienarchäologisches Interesse für frühe utopische Technologiephantasien der Avantgarde wahrnehmbar, das symptomatisch für ein signifikant verändertes Verhältnis zur Utopie bzw. zum Utopischen ist: Das Utopische löst sich von seinem eindeutig negativen, da politisch-totalitären Beigeschmack (verstanden als ‚Utopismus’) und wird wieder verstärkt positiv politisch konnotiert, d.h. als emanzipatives oder auch visionär-gespinsthaftes Potenzial verstanden (‚Utopizität’). / The dissertation researches a paradigmatic shift in the way artists reflect the historical avant-garde in visual and media art projects of the 1980s and 1990s in (ex-)Yugoslavia and Russia. The reasons for this paradigm shift can be found in the changing relationship to the notion of utopia, both in its political and its artistic connotation. In the 1980s, the reception both in so-called Soviet postutopianism (Il’ja Kabakov, Ėrik Bulatov, Oleg Vasil’ev, Komar & Melamid, Kollektive Aktionen) and in the Yugoslav retro-avant-garde (NSK, Mladen Stilinović, Malevič from Belgrads etc.) is characterized by a ‘discourse archeological’ interest in the potentially totalitarian elements of the avant-garde. Yet this point of view changes fundamentally during the 1990s in a younger generation of artists (neoutopianism and retroutopianism). Retroutopianism (Marko Peljhan, Vadim Fishkin) no longer primarily equates the utopianism of the avant-garde with totalitarian tendencies, but is reexamined with regard to its media-technological projections and designs, which were not only developed by individual avant-garde artists and theoreticians (Velimir Khlebnikov, Bertolt Brecht) but also by scientists and engineers during the early 20th century (Nikola Tesla, Herman Potočnik Noordung). Artistic projects of the time reveal an increasing ‘media-archeological’ fascination for the avant-garde's early utopian fantasies of technology. This fascination, in turn, is symptomatic for a significant change in the relationship to utopia and utopian thinking on the whole: utopian thinking per se separates from its unambiguously negative, political-totalitarian aftertaste (understood as 'utopianism') and takes on a new positive political connotation. It is now understood as an emancipatory or visionary-spectral potentiality ('utopicity').
