Sur un territoire, des sources sonores émettent des sons qui peuvent être d’origines anthropophoniques (i.e. le bruit des véhicules), biophoniques (i.e. les sons émis par les oiseaux), ainsi que géophoniques (i.e. le bruit du vent). Ceci permet de décrire un paysage sonore des lieux tout en alimentant des besoins particuliers propres à la cartographie de l’environnement sonore tels que les propriétés acoustiques des territoires, nécessaires à la compréhension de l’environne me nt sonore. Au-delà des travaux de recherches qui étudient et analysent les propriétés acoustiques de l’environnement, l’état de l’existant se concentre sur deux types de cartes sonores : les cartes d’inventaire de sons et les cartes de bruit. Deux approches méthodologiques sont à l’origine de la production de ces cartes. La première est basée sur des enregistrements sonores mesurés et géoréférencées sur le territoire à l’aide de sonomètres, ou d’applications installées sur des tablettes/téléphones intelligents. La deuxième sert à modéliser la propagation de l’onde acoustique en lien avec les objets présents sur le territoire (i.e. bâtiments, arbres, etc.). Bien que cette deuxième approche considère les différents facteurs environnementaux qui peuvent affaiblir l’onde acoustique comme l’absorption atmosphérique (causée par le vent, la température, etc.), la divergence géométrique et la nature de la couverture des sols, on constate qu’elle est peu documentée dans la littérature scientifique, lorsqu’aucun capteur sonore n’est utilisé pour produire des cartes sonores. L’objectif principal est de définir une méthode générique de modélisation de la propagation acoustique du son pour territoire à l’aide de données géospatiales multi-sources, dont des images à très haute résolution. Ainsi à l’aide des outils géomatiques, il est possible de représenter l’interaction qui existe entre l’onde sonore et les objets environnementaux composant ce territoire. Il est alors possible à partir d’une source sonore et des points récepteurs du son de réaliser des cartes dites spatio-phoniques. Mots clés : environnement sonore, modélisation, géomatique, propagation, données géospatiales, cartographie / On a territory, sound sources emit sounds that can be of anthropophonic origins (i.e. vehicle noise), biophonic origins (i.e. sounds emitted by birds), as well as geophonic origins (i.e. wind noise). This makes it possible to describe a soundscape of the places while feeding particular needs specific to the mapping of the sound environment such as the acoustic properties of the territories, necessary to the understanding of the sound environment. Beyond the research work that studies and analyzes the acoustic properties of the environment, the state of the existing focuses on two types of sound cards: sound inventory cards and noise maps. Two methodological approaches are behind the production of these cards. The first is based on sound recordings measured and georeferenced on the territory using sound level meters, or applications installed on tablets/smartphones. The second is used to model the propagation of the acoustic wave in relation to the objects present on the territory (i.e. buildings, trees, etc.). Although this second approach considers the different environmental factors that can weaken the acoustic wave like atmospheric absorption (caused by wind, temperature, etc.), the geometric divergence and the nature of the cover of soil, it is found that it is poorly documented in the scientific literature, when no sound sensor is used to produce sound cards. The main objective is to define a generic method for modeling the acoustic propagation of a territory using multi-source geospatial data including very high resolution images. Thus, using geomatic tools, it is possible to represent the interaction that exists between the sound wave and the environmenta l objects that make up this territory. It is then possible from a sound source and sound receiving points to make so-called spatio-phonic cards

Femtocell is a small cellular base station used by operators to extend indoor service coverage and enhance overall network performance. In Long Term Evolution (LTE), femtocell works under macrocell coverage and combines with the macrocell to constitute the two-tier network. Compared to the traditional single-tier network, the two-tier scenario creates many new challenges, which lead to the 3rd Generation Partnership Project (3GPP) implementing an automation technology called Self-Organising Network (SON) in order to achieve lower cost and enhanced network performance. This thesis focuses on the inbound and outbound handovers (handover between femtocell and macrocell); in detail, it provides suitable solutions for the intensity of femtocell handover prediction, Physical Cell Identity (PCI) allocation and handover triggering parameter optimisation. Moreover, those solutions are implemented in the structure of SON. In order to e ciently manage radio resource allocation, this research investigates the conventional UE-based prediction model and proposes a cell-based prediction model to predict the intensity of a femtocell's handover, which overcomes the drawbacks of the conventional models in the two-tier scenario. Then, the predictor is used in the proposed dynamic group PCI allocation approach in order to solve the problem of PCI allocation for the femtocells. In addition, based on SON, this approach is implemented in the structure of a centralised Automated Con guration of Physical Cell Identity (ACPCI). It overcomes the drawbacks of the conventional method by reducing inbound handover failure of Cell Global Identity (CGI). This thesis also tackles optimisation of the handover triggering parameters to minimise handover failure. A dynamic hysteresis-adjusting approach for each User Equipment (UE) is proposed, using received average Reference Signal-Signal to Interference plus Noise Ratio (RS-SINR) of the UE as a criterion. Furthermore, based on SON, this approach is implemented in the structure of hybrid Mobility Robustness Optimisation (MRO). It is able to off er the unique optimised hysteresis value to the individual UE in the network. In order to evaluate the performance of the proposed approach against existing methods, a System Level Simulation (SLS) tool, provided by the Centre for Wireless Network Design (CWiND) research group, is utilised, which models the structure of two-tier communication of LTE femtocell-based networks.

This creative nonfiction dissertation is a memoir that probes the complex life and death of the author’s father, who became addicted in his late forties to crack cocaine. While the primary concerns are the reasons and ways in which the father changed from a family man into a drug addict, the memoir is also concerned with themes of family life, childhood, and grief. After his father’s death, the author moves to Las Vegas and experiences similar addiction issues, which he then explores to help shed light on his father’s problems. To enrich the investigation, the author draws from eclectic sources, including news articles, literature, mythology, sociology, religion, music, TV, interviews, and inherited objects from his father. In dissecting the life of his father, the author simultaneously examines broader issues surrounding modern fatherhood, such as cultural expectations, as well as the problems of emptiness, isolation, and spiritual deficiency.

<p>This dissertation deals with the history and memory of the Border War with China in contemporary Vietnam. Due to its particularity as a war between two neighboring socialist countries in Cold War Asia, the Border War has been a sensitive topic in Vietnam. While political sensitivity regarding the national past derives largely from the Party-State, the history and memory of the war has permeated Vietnamese society. The war's legacy can be seen in anti-China sentiments that, in the globalized neoliberal order, appear to be reviving alongside post-Cold War nationalism. The Border War against China represented an important nationalist turn for Vietnam. At the same time, the traumatic breakdown of the socialist fraternity cultivated anxiety over domestic and international relations. The recent territorial dispute over the South China Sea, between Vietnam and China, has recalled the history and memory of the war in 1979. The growing anti-China sentiment in Vietnam also interpellates the war as a near future.</p><p>As an anthropological approach to the history and memory of war, this dissertation addresses five primary questions: 1) how the historyscape of Vietnam's past has been shifted through politics on the Border War; 2) how the memoryscape involving the Border War has been configured as national and local experience; 3) how the Border War has shaped the politics of ethnic minorities in a border province; 4) why the borderscape in Vietnam constantly affects the politics of the nation-state in the globalized world order; and 5) why the border markets and trade activities have been a realm of competing instantiations of post-Cold War nationalism and global neoliberalism. </p><p>In order to tackle these questions, I conducted anthropological fieldwork in Lang Son, a northern border province and Ha Noi, the capital city of Vietnam from 2005 to 2012, and again briefly in 2014. A year of intensive fieldwork from 2008 to 2009 in Lang Son province paved the road to understanding the local history and local people's memory of the Border War in a contemporary social context. This long-term participant observation research in a sensitive border area allowed me to take a comprehensive view of how the memory of the Border War against China plays out in everyday life and affects the livelihood of the border's inhabitants. In Ha Noi, conducting archival research and discussing issues with Vietnamese scholars, I was able to broaden my understanding of Vietnamese national history and the socialist past. Because Vietnam is one of the countries with the fastest growing use of the Internet, I have also closely traced the emergence of on-line debates and the circulation of information over the Internet as a new form of social exchange in Vietnam. </p><p>As a conclusion, I suggest that memory and experience have situated Vietnam as a nation-state in a particular mode of post-Cold War nationalism, one which keeps recalling the memory of the Border War in the post-Cold War era. As the national border has been reconfigured by the legacy of war and by fluctuating border trade, the border challenges unbalanced bilateral relations in the neoliberal world order. The edge of the nation-state becomes the edge of neoliberalism in the contemporary world. The Vietnamese border region will continue to recall the horrors of nationalism and internationalism, through the imaginaries of socialist fraternity or in the practices off contemporary neoliberal multilateralism. </p><p>KEYWORDS: </p><p>Vietnam, China, Lang Son, the Border War, Memory, the Cold War, the post-Cold War, Neoliberalism.</p> / Dissertation

Ce mémoire décrit l’imaginaire sonore tel qu’il s’est transformé par l’apparition de dispositifs de reproduction (téléphone, phonographe et radio) à la fin du 19ème siècle et au début du 20ème siècle. Si ces appareils de reproduction sonore signalent un nouveau contexte socioculturel permettant la captation, la conservation et la transmission de manifestations sensibles, ils transforment également la manière de concevoir le son, ils modifient le statut de l’audition par rapport aux autres sens et reconfigurent un imaginaire qui traduit un rapport à soi, à autrui et au monde. Cette étude littéraire de la reproductibilité sonore propose une réflexion entre technologie et poétique en questionnant l’idée de communication. L’élément spécifique qui caractérise les appareils de reproduction sonore est un objet technique nommé «transducteur ». Je considère le transducteur à la fois comme métaphore et matérialité de médiation; conçu en termes de dispositif de transduction, ce concept permet une différente compréhension des pratiques sociales et de l’imaginaire constituant cet artefact culturel. / This thesis focuses on sound reproduction devices (telephone, phonograph and radio) that emerged in the late 19th and early 20th centuries. These aural technologies brought forth a new social and cultural context in which hearing became a distinctive characteristic of modern communication. But more importantly, they present new figures which translate different modalities of technological mediation. Technical means to inscribe, preserve, and broadcast matter are embedded socially in a constellation of institutions, practices and discourses ; they also configure particular relations that present a singular worldview that literary thought articulates. Understanding the unfolding of modern sound technologies and how we embody them calls for a critical account of a cordoned off visualist imaginary that accompanies technocultural analysis. This study takes up this question by elaborating a concept which encompasses the imaginary intertwined with sound reproduction media. The telephone, the phonograph and radio use a device called a « transducer ». By conceiving this specific object’s tropological and material structure, I argue that this transduction apparatus presents a new interpretative model that conveys the resonance of modern auditory cultural productions.

This study analyzed male high school students' perceptions of the child development course and father role. A two-part questionnaire was administered to 192 males. In Part I, descriptive statistics determined that more males would enroll in child development if the female-oriented image was changed, if they knew more about the course, and if their friends enrolled. In Part II, a t-test was used to analyze the results of the FRO. Six hypotheses examined the perceptions of males with and without parent training toward father roles of nurturing, problem solver, provider, societal model, recreational, and total scores of both groups. Results indicated males without parent training had a more traditional view toward the problem-solver role.
