Cette thèse mène une enquête sur la parution d'un certain nombre de décors à sujet littéraire dans des demeures aristocratiques pendant la période qui va du règne de Henri IV jusqu'aux débuts de la Régence d'Anne d'Autriche, notamment pendant les années 1620 et 1630. La littérature critique a déjà montré l'importance de certains sujets tirés des œuvres littéraires dans les commandes de Henri IV et de Marie de Médicis : la "Franciade", les "Éthiopiques," "Jérusalem Délivrée". le "Pastor Fido". Il s'agit. pour la plupart, de sujets qui jouiront ensuite d'une fortune particulière chez la noblesse. soit la plus proche à la couronne que la plus "dégagée" et éloignée de la cour. Pendant les mêmes années, avec "L 'Astrée", le "Don Quichotte" et bien d'autres, le roman commençait à s’imposer en genre autonome, destiné à devenir un véritable lieu de représentation mais aussi de formation e de réflexion de société et de la culture de l'Europe moderne. En effet aussi les héros épiques. qui s'imposaient en peinture mais même sur scène - en protagonistes des ballets de cour, des tragédies et des tragicomédies - étaient de plus en plus lus interprétés sous une lumière romanesque, Les arts figuratifs participaient donc. de leur façon, à cette évolution. qui représente l'un des nœuds fondamentales de notre histoire culturelle. En partant du cas spécifique des décors à sujet littéraire. la restitution des différentes commandes. des différentes façon de "lire" ces récit littéraires e de les mettre en images. ainsi que les rapports entre mécénat artistique. mécénat littéraire et. plus en général, les liens entre culture et peinture. sont donc but ultime de ce travail. / This thesis investigates a number of pictorial decorations with literary subject in French aristocratic houses during the period from the reign of Henry IV to the beginning of the regency of Anne of Austria, especially during the 1620's and 1630·s. Critical literature has shown the important reference to the literature in pictorial patronage of Henry IV and Marie de 'Medici: from the Franciade to the Ethiopiques, from the Jérusalem Dclivercd, to the Pastor Fido. In a larger part, those subjects enjoyed a great fortune also in aristocratic patronage of crown ministers as weil as of some rebel "frondeur". During the same years, with the publication of Honoré dUrfé's .Astrée, Cervantes ' Don Quixote and many others, the novel began to impose itself as autonomous genre, to becorne an important instrument of representation but also a way of training and reflection on society and culture of modern Europe. Indeed as the epic heroes. who appeared in painting but even on stage - as protagonists of court ballets, tragedies and tragicomedies - were increasingly read and interprete in a "novel' light. So, figurative arts were involved - in their way - to this development, which is one of the nodal points of our cultural history. Starting from the specific case sets a literary subject, the ultirnate goals of this work are the analysis of the different cornmands, the different way to "read" these "histories" and to translate them in images, and the relationships between artistic patronage. literarv patronage and, in general, the links between culture and painting.

Let G be a split semisimple algebraic group over a field k. Our main objects of interest are twisted forms of projective homogeneous G-varieties. These varieties have been important objects of research in algebraic geometry since the 1960's. The theory of Chow motives and their decompositions is a powerful tool for studying twisted forms of projective homogeneous varieties. Motivic decompositions were discussed in the works of Rost, Karpenko, Merkurjev, Chernousov, Calmes, Petrov, Semenov, Zainoulline, Gille and other researchers. The main goal of the present thesis is to connect motivic decompositions of twisted homogeneous varieties to decompositions of certain modules over Hecke-type algebras that allow purely combinatorial description. We work in a slightly more general situation than Chow motives, namely we consider the category of h-motives for an oriented cohomology theory h. Examples of h include Chow groups, Grothendieck K_0, algebraic cobordism of Levine-Morel, Morava K-theory and many other examples. For a group G there is the notion of a versal torsor such that any G-torsor over an infinite field can be obtained as a specialization of a versal torsor. We restrict our attention to the case of twisted homogeneous spaces of the form E/P where P is a special parabolic subgroup of G. The main result of this thesis states that there is a one-to-one correspondence between h-motivic decompositions of the variety E/P and direct sum decompositions of modules DFP* over the graded formal affine Demazure algebra DF. This algebra was defined by Hoffnung, Malagon-Lopez, Savage and Zainoulline combinatorially in terms of the character lattice, the Weyl group and the formal group law of the cohomology theory h. In the classical case h=CH the graded formal affine Demazure algebra DF coincides with the nil Hecke ring, introduced by Kostant and Kumar in 1986. So the Chow motivic decompositions of versal homogeneous spaces correspond to decompositions of certain modules over the nil Hecke ring. As an application, we give a purely combinatorial proof of the indecomposability of the Chow motive of generic Severi-Brauer varieties and the versal twisted form of HSpin8/P1.

Indiana University-Purdue University Indianapolis (IUPUI) / Two impulsivity-related traits, negative and positive urgency (i.e., the tendency to act rashly in the face of extreme negative and positive emotions, respectively) are important risk factors for alcohol use escalation during college and for problematic and disordered level alcohol use, in part through increasing motives for alcohol use. The majority of research to date has focused on the causal direction from trait to motives to alcohol consumption. The goal of the current study was to conduct an initial test of how continued and escalating alcohol use may drive increases and shifts in positive and negative urgency, and how such changes drive subsequent increased drinking motives over the first year of college. Data were analyzed using an archival dataset of 418 first-year college students (age 18-21) enrolled in an introduction to psychology course at a large Midwestern university. Participants were sampled at three timepoints: at the beginning of the fall semester, the end of the fall semester, and the end of the spring semester. A series of hierarchical multiple regression and mediation analyses were used to test study hypotheses. Changes in alcohol use did not predict later changes in positive and negative urgency. Results did replicate previous research showing that changes in positive and negative urgency predicted later changes in drinking motives. Finally, there was some evidence that alcohol use at baseline predicted changes in enhancement drinking motives through changes in positive urgency; but this pattern was not seen with negative urgency. This work extends existing work with urgency theory, which has primarily focused on the effects of urgency on subsequent alcohol consumption and not the inverse. The fact that alcohol use drives subsequent changes in positive urgency and drinking motives can help to better identify mechanisms contributing increased risk for transition to problematic levels of alcohol consumption, can lead to better identification of those at risk for problematic alcohol use and can set the stage to better integrate urgency theory with other well-established alcohol risk models.

This dissertation argues how motivic saturation on the musical surface complicates a conventional harmonic interpretation in Fauré's late chamber works. Using motivic segmentation and linear analysis, I illustrate how the abundance of foreground motives has far-reaching implications for tonal voice leading and overall coherence. The outcomes of motivic saliency are twofold, influencing harmonic progressions by 1) altering traditional syntax or 2) replacing traditional syntax to provide the primary form of tonal coherence. I unpack the voice-leading consequences of stratifying motives over one another and bring in two larger, emerging concepts: 1) key duality as disjunction between melody and bass and 2) tonal coherence from the tonal profile of motives. In the first case, either the melody or the bass projects its own center or key separate from the other parts, producing a sensation of key duality. In the second, a single motive furnishes the main source of tonal grounding by unfolding a structural harmony that the surface sonorities obscure. While motivic saliency is a consistent trait across Fauré's late repertoire, the two phenomena above increase over time.

This study proposes that members of Greek social organizations have higher rates of binge drinking as compared to other college students due to their greater acceptance of norms and motives that support binge drinking. The College Alcohol Study, a survey conducted by the Harvard School of Public Heath, was administered to 10, 904 university students. The survey measured various aspects of students' experiences at their respective universities including experiences with and perceptions of alcohol use. Logistic regression analysis was used to determine normative and motivational predictors of binge drinking for Greek and non-Greek students. The results show that Greek members binge drink at higher levels than do other students. The results also indicate that social norm and motive variables, which were thought to be predictive of binge drinking practices for all students, are better predictors of binge drinking for non-Greek members. Implications of theses findings, discussion of results, limitations of the study, and recommendations for future research are presented.
