In the eighteenth and early nineteenth centuries, the duel of honor functioned as a formal recourse to attacks on a gentleman's reputation. Concurrently, many notable literary figures such as Samuel Johnson, William Gifford, Thomas Moore, and Lord Byron were involved in literary disputes featuring duels or the threat of physical violence, a pattern indicating a connection between authorship and dueling. This study explicitly examines this connection, particularly as it relates to social acceptance, the gentrification of authorship, and the business of publishing. The act of publishing, putting one's work into the public sphere for consumption as well as critique, created an acute sensitivity to issues of honor because publishing automatically broadcast insults or accusations of dishonorable conduct to the reading public. This study requires a grounded discussion of complex, interconnected concepts, specifically: masculine identity, social hierarchy, and violence; satire; dueling; and authorship. Discussion moves from a foundational concern with violence and the assertion of social status, to the relationship between status and honor, to specific modes of defending honor, and finally to the attempt to establish authorship as an honorable profession. Although each of these quarrels exhibits physical violence or the threat of physical violence, these examples also exhibit verbal violence through satiric assaults or an exchange of verbal attacks and parries. As professional writers struggled to overcome the stereotype of the literary hack and gain social respectability, dueling, with either lead or paper bullets, became a way for authors to defend and maintain the fragile social status they had gained. / Master of Arts

Dans cette thèse, nous étudions des problèmes de prise de décisions séquentielles dans lesquels, pour chacune de ses décisions, l'apprenant reçoit une information qu'il utilise pour guider ses décisions futures. Pour aller au-delà du retour d’information conventionnel tel qu'il a été bien étudié pour des problèmes de prise de décision séquentielle tels que les bandits multi-bras, nous considérons des formes de retour d’information partielle motivées par des applications pratiques.En premier, nous considérons le problème des bandits duellistes, dans lequel l'apprenant sélectionne deux actions à chaque pas de temps et reçoit en retour une information relative (i.e. de préférence) entre les valeurs instantanées de ces deux actions.En particulier, nous proposons un algorithme optimal qui permet à l'apprenant d'obtenir un regret cumulatif quasi-optimal (le regret est la différence entre la récompense cumulative optimale et la récompense cumulative constatée de l’apprenant). Dans un second temps, nous considérons le problème des bandits corrompus, dans lequel un processus de corruption stochastique perturbe le retour d’information. Pour ce problème aussi, nous concevons des algorithmes pour obtenir un regret cumulatif asymptotiquement optimal. En outre, nous examinons la relation entre ces deux problèmes dans le cadre du monitoring partiel qui est un paradigme générique pour la prise de décision séquentielle avec retour d'information partielle. / The multi-armed bandit (MAB) problem is a mathematical formulation of the exploration-exploitation trade-off inherent to reinforcement learning, in which the learner chooses an action (symbolized by an arm) from a set of available actions in a sequence of trials in order to maximize their reward. In the classical MAB problem, the learner receives absolute bandit feedback i.e. it receives as feedback the reward of the arm it selects. In many practical situations however, different kind of feedback is more readily available. In this thesis, we study two of such kinds of feedbacks, namely, relative feedback and corrupt feedback.The main practical motivation behind relative feedback arises from the task of online ranker evaluation. This task involves choosing the optimal ranker from a finite set of rankers using only pairwise comparisons, while minimizing the comparisons between sub-optimal rankers. This is formalized by the MAB problem with relative feedback, in which the learner selects two arms instead of one and receives the preference feedback. We consider the adversarial formulation of this problem which circumvents the stationarity assumption over the mean rewards for the arms. We provide a lower bound on the performance measure for any algorithm for this problem. We also provide an algorithm called "Relative Exponential-weight algorithm for Exploration and Exploitation" with performance guarantees. We present a thorough empirical study on several information retrieval datasets that confirm the validity of these theoretical results.The motivating theme behind corrupt feedback is that the feedback the learner receives is a corrupted form of the corresponding reward of the selected arm. Practically such a feedback is available in the tasks of online advertising, recommender systems etc. We consider two goals for the MAB problem with corrupt feedback: best arm identification and exploration-exploitation. For both the goals, we provide lower bounds on the performance measures for any algorithm. We also provide various algorithms for these settings. The main contribution of this module is the algorithms "KLUCB-CF" and "Thompson Sampling-CF" which asymptotically attain the best possible performance. We present experimental results to demonstrate the performance of these algorithms. We also show how this problem setting can be used for the practical application of enforcing differential privacy.

This dissertation explores the representation of dueling and honor in five theatrical works in order to answer one central question: How does the Golden Age concept of honor transform in the age of Enlightenment? This question may be broken down into specific inquiries, such as: 1) How is honor filtered through sentiment? 2) How did eighteenth-century ilustrados use theater to attempt to resolve the conflict between using violence to defend one’s honor and the Enlightenment ideal of avoiding excess? and 3) How did honor affect the private citizen and his relationship to the state in plays? During the eighteenth century, the age of sensibility rewrote the duel, transforming it from a ritual connected with the aristocracy into an act tied to individual, often middle-class lives. This project begins with an early play by José de Cañizares, Por acrisolar su honor (1711) and then examines sentimental comedies published and performed toward the end of the century: Gaspar Melchor de Jovellanos’ El delincuente honrado (1773), Luciano Francisco Comella’s La Jacoba (1789), Antonio Valladares de Sotomayor’s El vinatero de Madrid (1784) and Gaspar Zavala y Zamora’s El amante generoso (1791). Sentimental comedies use sensibility to focus on individuals’ honor conflicts. An analysis of the representation of dueling offers a glimpse of the complex intermingling of multiple definitions of Spanish culture, where neither a lone enlightened model nor an identity based primarily on Spain’s Baroque past prevails. While sentimental comedies present conclusions that ostensibly exalt honor as virtue and rely on a belief in humanity’s goodness to resolve their conflicts, their representations of dueling point to a tense coexistence of multiple definitions of Spanish identity in the eighteenth century. Virtue is never enough to override the accusation that someone is a coward for not accepting a dueling challenge. The inclusion of extra elements that cater to social prejudices of the time also undermines the notion of honor-as-virtue. The contradictions revealed by sympathetic representations of dueling may point to the failure of sensibility as a cohesive model for resolving dramatic conflicts in a society with such diverse definitions of honor and citizenship.

In the United States of America (U.S.), institutional marginalization and racial discrimination remains an arguably difficult subject to understand, both conceptually and pragmatically. Regarding governmental sectors, U.S. Armed Forces are institutions where discrimination must be critically explored in an attempt to provide an understanding of the reality faced by those who actually serve. This study involved the examination into racism within a specific elite governmental sector that emphasizes a philosophy of a unified oneness of all its members. Using a phenomenological approach, the study delved into the actual impact of racism within the Marine Corps, on the lives of individual members of a historically marginalized populace, African American/Black. The research explored and analyzed the life stories of three male members of the aforementioned population group, hence seeking to answer the research question: How has Integrated Racial Diversity in the Armed Forces Impacted Experiences of Discrimination Antagonistic to Male African American/Black Marine Corps Officers as Members of a Population Historically Marginalized and Discriminated against in the United States of America? Theories incorporated in the research offered meaning to the experiences of the individual participants. Discoveries illustrated the necessity of adaptation by the individual in coping with the impact of racially charged hostilities in an environment supposedly operating with an objective of oneness of its members. Through the findings, a theory of socio-psycho-bio dissonance was developed by the researcher. This research provides recommendations on practical ways to transformatively address and seek probable resolution in conflict – institutionally.
