La pensée politique à l’époque de Justinien (527-565) : l’Ekthesis d’Agapète et le Dialogue de science politique

The object of this thesis is to study two important texts of the political thought of the Age of Justinian by replacing them in the political context of the Age.  The two texts represent the point of view of two acceptation groups of Constantinople – groups that can participate in the election or the destitution of an emperor : the clergy and the elite of the senators and the high spheres of the bureaucracy.  What will emerge is a clash between two tendencies : on the one hand a christianised political hellenism (associated with the clergy) and on the other a roman vision mixed to neoplatonician metaphysics (associated with senators and the high spheres of the bureaucracy). The two tendencies/traditions ask different questions. The first one asks the questions of the orthodoxy of the emperor and of the necessity for him to follow the rules of christian ethics, as well as to show himself worthy of God, of whom he is the servant; the other, the question of the preservation of the roman heritage, particularly in regards of the role of the Senate and the importance of the law, and of the relation between imperial power and philosophy.

La correspondance transatlantique des Prize Papers (1744-1763) : famille, commerce et communications en temps de guerre

Between 1744 and 1763, two major wars shook the Atlantic world. France and her colonies struggled against the British empire. Both belligerents made considerable use of privateers. Beyond its obvious commercial and military consequences, this form of maritime warfare disrupted transatlantic communications. The letters carried by a prize were often lost or, at best, were confiscated, interrupting postal communications. The Prize Papers archives, which contain letters and other documents confiscated by British privateers, embody this reality. The collection includes numerous intercepted French letters. Many of them will be analyzed here, by way of showing the potential of this collection for the study of the French transatlantic communications system and its main actors in wartime. The constitution of this very special archive is presented first. Correspondents’ transatlantic communications practices as they evolved in wartime are analyzed next. Finally, the types of information transmitted in this difficult context are the subject of the last part of the thesis.

Hors champ, suivi de Aquin demeure

Hors champ (Offscreen) is a collection of short stories and poems that offers rewrites of striking works of contemporary Quebec literature from 1960 to the present. In this collection, the literary legacy is problematized by the bursting of the source of hypotexts. Thus, the rewriting is done by recovering certain formal characteristics of source texts, while putting forward new thematic content. The texts relate to many affiliations, offering not a static and overwhelming posterity, but rather an active heritage, fragmented and drawing from several sources — as Quebec literary heritage does. The stories in the collection do not clearly announce their hypotext but rather begin with an epigraph, as a way to play with the readers’ expectations. The architecture of the collection does not respect the chronological order of hypotexts, and short stories from the same source are not grouped together.   Aquin demeure (Aquin remains) compares two contemporary Quebec novels : Ça va aller by Catherine Mavrikakis and Pourquoi Bologne, by Alain Farah. Starting from the observation that the figure of Hubert Aquin exerts a spectral presence on Quebec literature and has bequeathed a problematic and paradoxical legacy to posterity, the project aims to see what readings of this aquinien heritage the works of Mavrikakis and Farah offer. The analysis of Ça va aller begins with a comparative study of the two authorial figures whom are being presented : Hubert Aquin and Robert Laflamme, an avatar of Réjean Ducharme. The study seeks to show how Aquin’s literary legacy is unattainable for the narrator while the analysis of Pourquoi Bologne focuses on the rewrite of Prochain épisode. With Genette’s notions of intertextuality and hypertextuality, the study attempts to determine whether it is possible to consider Pourquoi Bologne a text in the second degree.

La persistance du désir chez Diadorim

This study aims to analyze how the body is represented in João Guimarães Rosa’s novel Grande sertão: veredas, by looking into each of the most important encounters between Diadorim and Riobaldo, the two main characters of this story. The first time they meet on the banks of the river de Janeiro, when they are still youngsters, Diadorim’s body cannot be fully represented by the narrator’s speech.  Their second encounter, when adults and members of a gang of jagunços, confirms such limitations. Each name Riobaldo uses to address Diadorim and the suspense he generates contribute to enhance the enigmatic effect caused by his companion’s body. The ambiguity surrounding Diadorim’s sexuality becomes a constant aspect throughout the novel. The last encounter happens when Diadorim is found dead. Only then his feminine nature is revealed. However, Riobaldo is not able to fully acknowledge this finding and needs to repeat in words the moments he shared with Diadorim by telling their story to an interlocutor in an attempt to decode the mysteries surrounding his companion. This analysis explore these three key moments and examines how the mystery is structured around Diadorim’s body.

Évaluation du rôle des caractéristiques personnelles des enquêteurs policiers sur la conduite d'entrevues d’enquête auprès d’enfants victimes d’agression sexuelle

Since the 1990’s, disclosure of child sexual abuse (CSA) has been studied extensively. In addition to characteristics related to the child and the context of the CSA, the types of questions used by investigative interviewers (ex. invitations and open-ended questions) are another critical component for the child’s disclosure and the amount of details provided by the child related to the incident. Despite their participation in training programs, few investigative interviewers use open-ended questions once in the field. This research project aims to determine whether certain personal characteristics are related to investigators’ adherence to a structured interview protocol, their use of open-ended questions in an investigative interview with a child victim of sexual abuse and the amount of details obtained from the child during this interview.  Two studies were conducted to attempt to answer this question. The first study was conducted at the École nationale de police du Québec with 24 French Canadian police investigators after following a one-week training program aimed at using the National Institute of Child Health and Human Development (NICHD) interview protocol. These investigators performed a mock interview at the end of their training to test their practical competence. Interview performance was positively related to cognitive abilities, female gender, and the personality trait Openness to Experience and negatively to stress management and investigator’s experience.   The second study was conducted with 13 police investigators from the Service de police de la Ville de Montréal. A total of 114 real investigative interviews conducted with child victims of sexual abuse were collected and scored. Results showed that emotional intelligence, and the personality traits of Extraversion, Agreeableness and Conscientiousness were positively related to adherence to the NICHD interview protocol and the ratio of open-ended questions. The number of years of experience and personality trait Neuroticism were negatively related with these two performance criteria. Cognitive abilities were related to the amount of details obtained from the child per question.   The interpretations of these results and their implications for the selection and training of investigative interviewers are discussed.

Rêves et émotions chez des sujets souffrant du trouble comportemental en sommeil paradoxal

REM sleep behavior disorder (RBD) is a parasomnia characterized by vivid dreams and loss of muscle atonia usually present during REM sleep that allows the appearance of dream-enacting behaviors that are isomorphic to dream content. Several studies have examined the content of RBD patients’ dreams, many found a greater presence of threatening and aggressive themes, others obtained mixed results. Most studies had significant methodological shortcomings, such as a lack of a control group or the inclusion of patients taking psychoactive medication. Still, the presence of dysphoric dreams is associated with marked psychopathology and emotional regulation problems. Moreover, the reason why RBD patients have dysphoric dreams is largely unexplored, just as parts of the processes that generate the dream-enacting behaviors.  The goal of the first article of this thesis was to measure alexithymia and nightmare distress among RBD patients compared to a control group. The results indicate that RBD patients suffer more from alexithymia, especially a greater difficulty in identifying their emotions and that this difficulty correlated with nightmare distress. The second article examined, using a validated questionnaire, the lifetime prevalences of patients’ typical dream themes, and estimated the presence of their dreams, nightmares and dream theme diversity. RBD patients reported significantly more nightmares than controls and more menacing themes, such as assaults, disasters, and where the dreamer lacks control. The third article was intended to clarify discrepancies in the results of studies on RBD dreams, that is, if the aggressiveness reported by patients is really a difference in dream content or rather a problem related to dream distress. A second objective was to measure the degree of correlations between waking-state behaviors such as mirror behaviors, and dream-enacting behaviours in RBD patients. RBD patients were found to have more dysphoric dreams, containing more anxiety. They were also feeling greater distress in reaction to their dream experiences than did controls. Moreover, their results on the mirror behavior questionnaire correlated with the severity of their dream-enacting behaviors, suggesting that the mirror neuron system could have an influence in the formation of these behaviors.  Overall, these findings suggest that difficulties in emotional regulation could explain both patients’ daytime emotional symptoms (alexithymia, nightmare distress, depression, anxiety, fewer mirror behaviors) and nocturnal difficulties (nightmares and dysphoric dreams, threats in dreams). We suggest that a deficit in frontal regulatory regions could be the base of the different challenges faced by patients. More specifically, it is possible that abnormalities in the mirror neuron system have an impact on both patients' ability to regulate their emotions and the manifestation of dream-enacting behaviors.

Entrevues auprès d’enfants qui dévoilent une agression sexuelle : examen du processus d’enquête et du parcours judiciaire des dossiers

This thesis aimed to explore the contribution of contextual variables to the formal disclosure of alleged child sexual abuse victims as well as to the legal proceedings of their case.  More specifically, the first article examined the predictive value of child sexual abuse’s characteristics (relationship between the child and the suspect, reported coercion, type and frequency of abuse) as well as the disclosure context (purposeful or accidental disclosure, maternal belief and protective actions) on the proportion of central forensically relevant (CFR) details elicited during the investigative interview. The study also controlled for the well documented effects of the child’s age and use of the National Institute of Child Health and Human Development (NICHD) Investigative Protocol. All these variables were collected from 116 interview transcripts and child sexual abuse files. As expected, results from hierarchical regression showed that adhesion to the NICHD Protocol and the child’s age were the two strongest predictors of the proportion of CFR details obtained. Coercion (physical and verbal) as well as the presence of a protective mother also increased the proportion of CFR details obtained. Explanations for these results are discussed, as well as the study’s limitations and implications for further research.  The second article explored the predictive value of the characteristics of the child, sexual abuse, shared custody, disclosure context, available evidence and investigative interviews on the investigators’ decision to substantiate the complaint and on the district attorney’s decision to authorize its proceeding in court. These characteristics were collected from 169 child sexual abuse police files and interview transcripts. Results show that 117 files out of 169 (69%) were classified as substantiated by the investigators. Logistic regression reveal that the child’s age, an accidental disclosure, the choice of the first person who received the disclosure, the frequency of the abuse, and the suspect’s corroboration were significant predictors in finding the case substantiated. Of these 117 substantiated files submitted to the district attorneys, 96 of them (82%) were authorized to proceed in criminal court. Significant predictors on the district attorneys’ level were the corroboration of the suspect, the protection offered by the mother following her child’s disclosure, the adhesion to the NICHD investigative Protocol and the corroboration of the witness which increased the chances of authorizing the case whereas the child’s age diminished it. The results are discussed, as well as well as the study’s limitations and implications for further research.

Géométrie nodale et valeurs propres de l’opérateur de Laplace et du p-laplacien

The main topic of the present thesis is spectral geometry. This area of mathematics is concerned with establishing links between the geometry of a Riemannian manifold and its spectrum. The spectrum of a closed Riemannian manifold M equipped with a Riemannian metric g associated with the Laplace-Beltrami operator is a sequence of non-negative numbers tending to infinity. The square root of any number of this sequence represents a frequency of vibration of the manifold.   This thesis consists of four articles all related to various aspects of spectral geometry. The first paper, “Superlevel sets and nodal extrema of Laplace eigenfunction”, is presented in Chapter 1. Nodal geometry of various elliptic operators, such as the Laplace-Beltrami operator, is studied. The goal of this paper is to generalize a result due to L. Polterovich and M. Sodin that gives a bound on the distribution of nodal extrema on a Riemann surface for a large class of functions, including eigenfunctions of the Laplace-Beltrami operator. The proof given by L. Polterovich and M. Sodin is only valid for Riemann surfaces. Therefore, I present a different approach to the problem that works for eigenfunctions of the Laplace-Beltrami operator on Riemannian manifolds of arbitrary dimension.   The second and the third papers of this thesis are focused on a different elliptic operator, namely the p-Laplacian. This operator has the particularity of being non-linear. The article “Principal frequency of the p-Laplacian and the inradius of Euclidean domains” is presented in Chapter 2. It discusses lower bounds on the first eigenvalue of the Dirichlet eigenvalue problem for the p-Laplace operator in terms of the inner radius of the domain. In particular, I show that if p is greater than the dimension, then it is possible to prove such lower bound without any hypothesis on the topology of the domain. Such bounds have previously been studied by well-known mathematicians, such as W. K. Haymann, E. Lieb, R. Banuelos, and T. Carroll. Their papers are mostly oriented toward the case of the usual Laplace operator. The generalization of such lower bounds for the p-Laplacian is done in my third paper, “Bounds on the Principal Frequency of the p-Laplacian”. It is presented in Chapter 3.  My fourth paper, “Wolf-Keller theorem of Neumann Eigenvalues”, is a joint work with Guillaume Roy-Fortin. This paper is concerned with the shape optimization problem in the case of the Laplace operator with Neumann boundary conditions. The main result of our paper is that eigenvalues of the Neumann boundary problem are not always maximized by disks among planar domains of given area. This joint work is presented in Chapter 4.

Modèles et méthodes pour la planification de la récolte forestière

Harvest planning has different levels according to the time horizon of the problem and the nature of the decisions to be taken. Initially, we are interested in an annual harvest scheduling problem, halfway between tactical and operational planning. This problem applied in Qu\'ebec, is motivated by a need from the industry for an integrated tool that provides annual schedules to harvest teams. The integration is to determine demand driven assignments of teams to cutblocks and to manage transportation and inventory accordingly.   Several MIP models have been formulated, and three solution approaches have been developed according to the structure of each model. The rolling horizon approach performs better than the other two, by improving significantly from the traditional harvest plan, especially by reducing by half non delivered volumes or by dividing between 2 and 6 times volumes in storage when demands decrease.  Another contribution of the thesis is the creation of an interface to systematize solution process and to allow other users. This is the object of a transfer project between academics and industry.  The second problem is a Chilean tactical harvest planning. Harvesting decisions are driven by stochastic demands and prices of final products. The stochastic problem is solved using a heuristic based on a scenario decomposition technique. The number of scenarios considered is between 10 and 100 scenarios.   For each scenario, when the deterministic solution is feasible, it is compared with the stochastic solution for the current scenario.  The deterministic solution is only feasible for 10% of the scenarios, and induces losses of 9% in average.

L'ésotérisme de la dramaturgie platonicienne : un regard sur le Banquet et le Phédon

The present work has as its main focus Plato's dramaturgy in the Symposium and the Phaedo. The former studies both Alcibiades' speech and the epilogue whilst paralleling some of their elements with relevant passages from the Republic and the Seventh Letter. In doing so, it reveals an instance of Socratic withholding of information - as understood by the platonic school of Tübingen and Milan - and sheds light upon the existence of a set of unwritten doctrines philosophically higher than the ones contained in the dialogues. On the basis of these conclusions, I come to discern a hermeneutics in the epilogue according to which there are three hierarchical levels of comprehension to Plato's dialogues: exteriority, interiority of and oral philosophy - said three levels being symbolised by the comic poet Aristophanes, the tragic poet Agathon and the philosopher Socrates. The exegetic essay on the Phaedo revolves around Socrates' last will, which comes at the end of a ''dramatic'' sequence exceeding the bounds of the discursive philosophy that seeks to prove the immortality of the soul during the major part of the dialogue. By aiming at this sequence as well as at the introduction, one comes to see that comedy carries the mandate of counterbalancing tragedy in order to overcome the philosophically reprehensible emotions it fosters. Whilst contrasting tragedy and comedy, Socrates' last words fulfill, on a mimetic level, a paraenetic design, insofar as they invite the Athenian reader, indeed every reader, to philosophically overcome common places in regards to death.

Between pragmatism and the defence of a “Sister State”  : the national association for the advancement of colored people and the U.S. occupation of Haiti, 1915-1922

Initially, the news of the U.S. occupation of Haiti in 1915 generated little concern in the United States. Indeed, Haiti’s political instability made it such that a U.S. intervention seemed unavoidable. As of 1915 and especially 1920, the National Association for the Advancement of Colored People (NAACP), founded in 1909, denounced the U.S. interference in the Caribbean island. W.E.B. Du Bois and James Weldon Johnson, two of the association’s most influential black members, were deeply invested in condemning the U.S. occupation of Haiti. Historiographical tendencies have long located the NAACP’s engagement with Haiti in a conversation about black solidarity, but have failed to adequately consider the local politics that may have inspired the NAACP’s work. While this thesis does not refute the importance of black solidarity, it does recognise the limits of this conceptual approach in trying to explain the complexity of the NAACP’s work on the behalf of Haiti’s sovereignty. Placing more attention on the social and political context in the United States between 1915 and 1922 reveals that the NAACP utilised the occupation of Haiti as a means of attracting broader attention to domestic issues affecting black Americans, but also as a means of reinforcing the organisation’s own profile in the United States.
