Two of the leading methodologies for spatializing audio over multiple channels include non-real-time multi-track tape and variations of real-time systems that often involve complex configurations of hardware. Of the latter, composers relying on MIDI as a control source have used pairs of sound modules, effects units and automation capable mixers to achieve spatialization over four loudspeakers. These systems typically employ intensity panning, Doppler shifts and reverberation. The present research details the development of a compact spatialization system using a MAX patch controlling a Kurzweil K2500 sampler. This system supports real-time diffusion of up to six simultaneous sound files over eight loudspeakers while incorporating intensity panning, Doppler shifts, delays and filtering. The MAX patch allows composers to choose from several automatic sound spatialization trajectories or to use the mouse to draw and store their own trajectories for later playback. The piece, Circumfusion, is an eighteen-minute composition of electroacoustic music utilizing this spatialization system.

Combining quantitative sociophonetic methods and a qualitative, ethnographic acpproach to the study of language and social relations, my current research program focuses on the role of language in competing hip hop cultures. This research draws on early scholarship in cultural studies (Hebdige 1979), as well as what some have termed post- subcultural studies (Muggleton & Weinzierl 2003). Central to my own work are two theoretical concerns shared by these currents of scholarship, including: (1) How sociohistorical forces (including institutionally-mediated social action) shape cultural frameworks for symbolically staking out a position in the social landscape (2) How prominent social positioning in local cultral hierarchies shapes popular ideas regarding such intersecting notions as authentcity and indigeneity Regarding the first of these concerns, I examine how popular hip hop artists reflexively bring into focus a repertoire of spatialized social practices by rapping about them in their music -- a discursive practice I term metastylistic discourse. By selectively rapping about social practices indexical of their experiences of place, not only communicate a particular take on the local (i.e. their own); they directly position social and indirectly position soicolinguistic practices centrally among stylistic practices distinguishing Houston aeshetically from the cultural forms associated with other scenes. Central here is the second concern I share with current approaches to cultural studies, particularly, the significance of where social actors (i.e. established artists) find themselves in local social hierarchies. Established artists shape and reshape ways of talking about local life partly through econtextualizing prior texts. It is through the circulation of such texts that a discursive framework emerges, the product of a trans-modal series of recontexutalizations which serve to communicate an experience of Houston, what it looks and sounds like. In short, my current project works to close the gap between sociolinguistic approaches to the formation and interrogation of stylistic norms and research in cultural studies along these same lines (Hodkinson 2003, Piano 2003). By examining these processes in the context of hip hop, my work illustrates how social actors shape cultural norms through performance

The civil society and civic engagement is a prerequisite for democracy (Putnam, 1994), and in the form of the popular movements it has in many ways defined the Swedish democracy. This thesis focuses on the locality Holmsund located in the municipality of Umeå, Holmsund has a history that are in ways defined by activeness from civil society in similarity with many other places in Sweden (Ambjörnsson, 2001). Through interviews with people active connected to voluntary associations in Holmsund, and the use of narrative analysis this thesis tries to understand how what roles civil society has in Holmsund today; with specific interest in the rural context. Central to this is the understanding of space as relational and in many ways defined by power relations, and in particular relationship between centre-periphery. The combination of the centre-periphery relationship and the neo-liberal restructuring of the Swedish economy from being characterized by wealth distribution to wealth contributing in order to prosper has among other things lead to a decrease in services and increase inequality, both in urban peripheral places or as in this case, rural places. A part of how voluntary associations perceive their role in a rural and local context, is a role of counteracting the effects of inequality but mainly voluntary association are occupied with creating a good living environment within their local community. A part of the increasing inequality is that it enhances the identification with the local context which creates a common social reality among the inhabitants which serves as ground for organization. Through place attachment there seem to be an identification in between a significant presence and importance of civil society and the place Holmsund, this contributes to Holmsund being constructed as a civic community.

Consacrée à l’étude de rapports sociaux qui se nouent autour de la chasse, cette thèse se veut une contribution à une sociologie des modes de vie qui, prenant en charge l’inscription spatiale du social, permet de donner concrètement à voir la dimension relationnelle de la construction des classes sociales. La constitution des mondes de la chasse à l’échelle nationale est d’abord retracée et mise en perspective aux plans historique et socio-démographique. L’attention est en particulier orientée vers les transformations des conditions de la chasse en lien avec les évolutions récentes des espaces ruraux et périurbains. Les deuxième et troisième parties de la thèse se fondent principalement sur l’analyse de matériaux recueillis, selon des méthodes de type ethnographique, sur deux espaces contrastés : le Germanois (Côte-d’Or) et les environs bellifontains (Seine-et-Marne). Sur chaque terrain, différents groupements cynégétiques ont été observés : sociétés communales de chasse, groupes de chasse à tir privés, équipages de chasse à courre. Les manières dont leurs adhérents, qui appartiennent à des classes et des fractions de classes diverses, embrassent les enjeux auxquels ils sont confrontés – au premier rang desquels la dégradation de l’image de la chasse et l’environnementalisation de sa pratique – sont restituées. L’analyse se resserre ensuite autour des modalités organisationnelles et des logiques d’investissement dans la chasse privilégiées par les représentants de certaines fractions de classes ; celles-ci permettent de rendre compte des significations de leur engagement et de les réinscrire dans les styles de vie qui sont les leurs. / This thesis, studying the social relationships linked to hunting, is contributing to a sociology of the lifestyles that shows how social relationships are linked to space, and how social classes are built through interactions. The first part recounts the constitution of the different hunting worlds on a national level, using historical and socio-demographical perspectives. Special attention is laid on the transformation of the conditions of hunting due to recent evolution of the rural and periurban spaces. The second and third parts are mainly based upon the analysis of data, which were collected using ethnographical methods on two contrasted spaces: the Germanois (Côte-d'Or) and around Bellifontain (Seine-et-Marne). On each field, different hunting groups have been observed: district (“commune”) shooting groups, private shooting groups, hunting with hounds crews. The members of these groups belong to different classes and fractions of these classes. This thesis studies the differentiated ways they cope with what is nowadays at stake in their activity, essentially the deterioration of the image of hunting and the “environmentalization” of their practices. The analysis focuses then on how some of them, representing different social classes and fractions of classes, organize and involve themselves into hunting. It allows to present the meanings of their commitment in keeping with their lifestyles.

Sound localisation is one of the most representative function of the auditory system and, as such, it has been extensively investigated across species. Spatial hearing can be dramatically altered across the life span, yet research in humans have highlighted the remarkable capacity of the brain to adapt to changes of listening conditions, such as temporary ear plugging or long lasting hearing impairments. Although several investigations have examined accommodation to altered auditory cues (Chapter 1), a common theoretical framework seems to lack and a number of questions remain open. This limits the possibility to translate our current knowledge into concrete clinical applications for individuals who experience spatial hearing difficulties after hearing loss. The current dissertation reflects the attempt to answer specific questions regarding the process of sound localisation. The first study (Chapter 2) aimed to investigate the relation between different reference frames in spatial hearing, namely egocentric and allocentric sound representation. We studies this topic in the context of a learning paradigm, assessing to what extent localisation of single sounds in simulated monaural hearing (unilateral ear plugging) can improve following an audio-visual spatial hearing training focused on egocentric sound processing vs allocentric sound processing. An untrained group was also included in the study. We found that localisation performance in the horizontal plane improved specifically in the side ipsilateral to the ear-plug for all groups. Yet, the trained groups showed a qualitatively different change of performance after four days of multisensory ego/allocentric training compared to the untrained group, providing initial evidence of the possible role of allocentric coding in acoustic space re-learning. These results further highlight the importance of including a test-retest group in paradigms of sound localisation training. The second study (Chapter 3) focused on a specific aspect of the phenomenological experience of spatial hearing, namely the subjective confidence about the perceived sound position. We examined the relation between objective localisation accuracy and subjective certainty while participants localised sounds in two different listening conditions – binaural or simulated monaural hearing. Results showed that overall subjective certainty on sound position decreased in the altered listening condition (unilateral ear-plugging). In simulated monaural hearing, localisation accuracy and spatial confidence dissociated. For instance, there were trials in which participants were accurate, but felt uncertain, and trials in which they were less accurate but expressed higher ratings of spatial confidence on sound position. Furthermore, subjective confidence increased as a function of time within the testing block, and it was related to the spatial distribution of the perceived sound-source position. The third study (Chapter 4) exploited magnetoencephalography (MEG) to study the dynamics of the cortical network implied in active sound localisation. We implemented a novel apparatus to study sound localisation in MEG with real sounds in external space, and collected behavioural and subjective responses (i.e., accuracy and confidence, as in Study 2) during this altered listening condition. Results showed that participants were able to perceive the spatial difference between the positions of stimulation, thus proving the reliability of our novel setting for the study of spatial hearing in MEG. MEG data highlight a distributed bilateral cortical network involved in active sound localisation, which emerged shortly after stimulus presentation (100—125 ms). The network comprise the classical dorsal auditory pathway plus other cortical regions usually underestimated in previous literature – most notably, regions in the central sulcus/precentral gyrus possibly involved in head movements. Connectivity analysis revealed different patterns of neural coupling, as a function of frequency band. In particular, coherence in high gamma revealed significant connections involving the parietal cortex and the posterior superior temporal cortex. In the final chapter (Chapter 5), I summarise the main findings of the three studies, discuss their implications and outline potential future directions.

My work attempts to articulate how the format visual information is presented in changes our understanding of the visual information and our relationship to it. I explore analog and digital conversions, the audio and the visual sharing 3 dimensional space, and explore our relationship with screens, information and light. This paper discusses the ideas and underlying themes within my digital works that center around light as a form of information and communication. My work is also related to the transformation of technology that has occurred across many platforms throughout my lifetime. The most striking example is the telephone. The telephone has transitioned from an analog device on the wall that we speak into, to the phone we know today; a computer we carry around in our pocket with a screen we communicate through. This transformation of technology has changed our daily lives in ways past generations only dreamt of. We no longer log on or go online. We are always connected to a network of information, individuals and communities by an endless live stream of data. We live in an information super age, where we have access to nearly the entirety of knowledge humans have been able to acquire. Whether by reading by candle light, or a collection of pixels in the form of a screen, we use light to communicate all of these ideas and information. Social media, global positioning systems and on demand services have reached a point where our actions and nearly everything around us is tied to a computational system. My work attemps to bring this computational system into our physical space, where it can be acknowledged in the form of light and sound. / Master of Fine Arts / We live in an information super age, where we have access to nearly the entirety of knowledge humans have been able to acquire.

Depuis 2006, l’arrêt des pompages d’exhaure dans le Bassin Houiller Lorrain (France) a conduit à l’ennoyage des travaux miniers abandonnés, avec pour conséquence la mise en place d’un nouvel équilibre hydrodynamique régional. De récentes recherches portant sur l’exploitation de la chaleur des réservoirs ennoyés ont suscité de nouvelles interrogations, auxquelles nous nous sommes proposé de répondre. Notre travail avait pour objectif de chercher à comprendre le comportement thermo-hydrodynamique de l’eau de mine au sein d’un système en cours d’ennoyage ou récemment ennoyé. Dans un premier temps, les contextes géographique, géologique et hydrogéologique du Bassin Houiller Lorrain ont fait l’objet d’une synthèse, et une zone d’étude a été choisie. Dans un second temps, des profils de température et de conductivité électrique, complétés par des jaugeages, ont été mesurés dans d’anciens puits de mine du Bassin Houiller Lorrain, offrant une meilleure compréhension du comportement de l’eau à l’échelle d’un ouvrage profond. À partir de l’analyse de ces données, un modèle thermo-hydrodynamique et des simulations numériques ont pu être réalisés à cette échelle. Les résultats permettent d’expliquer les phénomènes observés. Leur stabilité est également étudiée. Dans un troisième temps, un modèle spatialisé maillé a été construit pour aborder la problématique du comportement hydrodynamique d’un réservoir minier entier. La montée de l’eau observée a été correctement reproduite ; le modèle peut par ailleurs être utilisé de façon prédictive pour la période suivant l’ennoyage. Plusieurs outils ont été testés, améliorés ou développés afin de faciliter l’étude des réservoirs ennoyés, notamment concernant l’homogénéisation tridimensionnelle des conductivités hydrauliques et le couplage d’un modèle spatialisé maillé avec un réseau de drains-conduits / Since 2006, cessation of dewatering in Lorraine Coal Basin (France) led to the flooding of abandoned mines, resulting in a new hydrodynamical balance in the area. Recent researches concerning geothermal exploitation of flooded reservoirs raised new questions, which we propose to answer. Our work aimed to understand the thermo-hydrodynamical behaviour of mine water in a flooding or flooded system. Firstly, we synthetized the geographical, geological and hydrogeological contexts of the Lorraine Coal Basin, and we chose a specific area for our studies. Secondly, temperature and electric conductivity log profiles were measured in old pits of the Lorraine Coal Basin, giving a better understanding of the water behaviour at a deep mineshaft scale. We were able to build a thermo-hydrodynamical model and simulate water behaviour at this scale. Flow regime stability is also studied. Thirdly, a hydrodynamical spatialized meshed model was realized to study the hydrodynamical behaviour of a mine reservoir as a whole. Observed water-table rise was correctly reproduced : moreover, the model can be used in a predictive way after the flooding. Several tools were tested, improved or developed to ease the study of flooded reservoirs, as three-dimensional upscaling of hydraulic conductivities and a coupled spatialized meshed model with a pipe network

Detta kandidatarbete handlar om att undersöka hur designprocessen för en postapokalyptiskmiljö kan gå till utan att förlita sig på det visuella, och istället skapa en helt auditiv upplevelse.För att utföra detta har vi i denna artikel samlat olika källor som berättar om vad en immersivmiljö består av och vilka avgörande faktorer en design måste ta hänsyn till. Dessa källor ärartiklar från till exempel Salselas och Penha (2019), och Smolicki (2019), men också existerandepostapokalyptiska medier som har analyserats efter vad som står i artiklarna. Denna textbeskriver också vår process för skapandet av en sådan gestaltning samt hur den implementerarden information som hittades i våra källor. Resultatet från undersökningen blev 2 olikapostapokalyptiska ljudscenarion designade av oss. Dessa tog stor hänsyn till Salselas och Penhasexempel på 3 olika ljud-egenskaper som har stor inverkan på lyssnarens immersion, och hurdessa 3 egenskaper implementeras inom andra postapokalyptiska medier. Immersion är en stordel av att skapa en ljudmiljö, de 3 ljud-egenskaperna som behövs är efterklang, bakgrundsljud,och spatialiserat ljud, och de medierna vi analyserade dessa i var filmen Book of Eli och serienThe Walking Dead / This bachelor thesis is about examining how the design process for a post-apocalypticenvironment can look without relying on the visual aspect, and instead create a completelyauditory experience. To achieve this, we have in this thesis gathered different sources thatexplain which aspects make an immersive environment, and which deciding factors we have totake into account as designers. These sources are articles, for example those written by Salselasand Penha (2019) and Smolicki (2019), but also existing post-apocalyptic pieces of media thathave been analyzed with the articles content in mind. This text will also explain our process forour designs, as well as how it implements the information we found in our sources. The result ofthis study turned out as 2 different post-apocalyptic sound scenarios designed by us. These tookSalsela’s and Penha’s 3 examples of characteristics that have a big impact on the listenersimmersion, into great consideration, and also how these 3 characteristics are implemented intodifferent post-apocalyptic pieces of media. Immersion plays a big part in creating a soundenvironment, the three characteristics needed are reverb, background sounds and soundspatialization, and the pieces of media we analyzed these characteristics in were the movie Bookof Eli and the tv-show The Walking Dead.
