The analytic component of the thesis approaches major questions in Cultural Studies, Philosophy and Social Theory through an investigation of various forms of creative practice. I approach the question of agency, for instance, through a study of stage actors, who must recite set lines, and yet feel empowered precisely by the opportunity to act through them. Investigation of the author's own work as a poet and novelist serves to cast light upon ideology, ie. how one might use a constrained language and yet feel empowered to speak new things through it. I apply these investigations to Althusser, whose famous essay on the total power of ideological interpellation is permeated with theatrical metaphor. I suggest that Althusser is repressing the creative component of everyday life, something social theory has ever found hard to theorise. I proceed to suggest that the place where such processes are analysed is in the philosophy of science. The work of Charles Saunders Peirce on the experimental method is, my investigation uncovers, surprisingly geared toward the investigation of creativity. In science one has a method for, and an extensive literature on, discovering new phenomena. My thesis is that the experimental method of modern scientists, and the creative method of modern writers, both geared toward the production of things that are at once new and true, is largely the same. I use Peircean semiotics to argue that creative composition is about listening to the languages spoken all round you, and transcribing their objective contours. So as to have effect on others. Which is just like science. And in both instances we are endlessly spoken through at every moment by the myriad languages which interpellate us. Whence creativity (for those who are open to it). My three portfolio pieces are: Cube Root of Book: a series of one hundred and thirty two poems set at intervals along the descending spiral of a Fibonacci number sequence. The 14th Floor, an Hypothesis, an experimental novel, written quite literally as an experiment; i.e. having written the novel, I then wrote up a prac-report detailing what I had learnt about the performance of writing, including the above. Unaustralia, a Study of Heads, an attempt to show the relevance of these findings to Cultural Studies and other related practices. It centres on my new reading of Althusser, and is flanked by mini-ethnographies of creative practice, including the above. The poetry is presented as a major new creative work. The experimental novel/ book of philosophy as a substantial contribution to knowledge.

Games have been used to evaluate and advance techniques in the eld of Articial Intelligence since before computers were invented. Many of these games have been deterministic perfect information games (e.g. Chess and Checkers). A deterministic game has no chance element and in a perfect information game, all information is visible to all players. However, many real-world scenarios involving competing agents can be more accurately modeled as stochastic (non-deterministic), im- perfect information games, and this dissertation investigates such games. Poker is one such game played by millions of people around the world; it will be used as the testbed of the research presented in this dissertation. For a specic set of games, two-player zero-sum perfect recall games, a recent technique called Counterfactual Regret Minimization (CFR) computes strategies that are provably convergent to an -Nash equilibrium. A Nash equilibrium strategy is very useful in two-player games as it maximizes its utility against a worst-case opponent. However, once we move to multiplayer games, we lose all theoretical guarantees for CFR. Furthermore, we have no theoretical guarantees about the performance of a strategy from a multiplayer Nash equilibrium against two arbitrary op- ponents. Despite the lack of theoretical guarantees, my thesis is that CFR-generated agents may perform well in multiplayer games. I created several 3-player limit Texas Holdem Poker agents and the results of the 2009 Computer Poker Competition demonstrate that these are the strongest 3-player computer Poker agents in the world. I also contend that a good strategy can be obtained by grafting a set of two-player subgame strategies to a 3-player base strategy when one of the players is eliminated.

This thesis presents work in the area of computer-animatedtalking heads. A system for multimodal speech synthesis hasbeen developed, capable of generating audiovisual speechanimations from arbitrary text, using parametrically controlled3D models of the face and head. A speech-specific directparameterisation of the movement of the visible articulators(lips, tongue and jaw) is suggested, along with a flexiblescheme for parameterising facial surface deformations based onwell-defined articulatory targets. To improve the realism and validity of facial and intra-oralspeech movements, measurements from real speakers have beenincorporated from several types of static and dynamic datasources. These include ultrasound measurements of tonguesurface shape, dynamic optical motion tracking of face pointsin 3D, as well as electromagnetic articulography (EMA)providing dynamic tongue movement data in 2D. Ultrasound dataare used to estimate target configurations for a complex tonguemodel for a number of sustained articulations. Simultaneousoptical and electromagnetic measurements are performed and thedata are used to resynthesise facial and intra-oralarticulation in the model. A robust resynthesis procedure,capable of animating facial geometries that differ in shapefrom the measured subject, is described. To drive articulation from symbolic (phonetic) input, forexample in the context of a text-to-speech system, bothrule-based and data-driven articulatory control models havebeen developed. The rule-based model effectively handlesforward and backward coarticulation by targetunder-specification, while the data-driven model uses ANNs toestimate articulatory parameter trajectories, trained ontrajectories resynthesised from optical measurements. Thearticulatory control models are evaluated and compared againstother data-driven models trained on the same data. Experimentswith ANNs for driving the articulation of a talking headdirectly from acoustic speech input are also reported. A flexible strategy for generation of non-verbal facialgestures is presented. It is based on a gesture libraryorganised by communicative function, where each function hasmultiple alternative realisations. The gestures can be used tosignal e.g. turn-taking, back-channelling and prominence whenthe talking head is employed as output channel in a spokendialogue system. A device independent XML-based formalism fornon-verbal and verbal output in multimodal dialogue systems isproposed, and it is described how the output specification isinterpreted in the context of a talking head and converted intofacial animation using the gesture library. Through a series of audiovisual perceptual experiments withnoise-degraded audio, it is demonstrated that the animatedtalking head provides significantly increased intelligibilityover the audio-only case, in some cases not significantly belowthat provided by a natural face. Finally, several projects and applications are presented,where the described talking head technology has beensuccessfully employed. Four different multimodal spokendialogue systems are outlined, and the role of the talkingheads in each of the systems is discussed. A telecommunicationapplication where the talking head functions as an aid forhearing-impaired users is also described, as well as a speechtraining application where talking heads and languagetechnology are used with the purpose of improving speechproduction in profoundly deaf children. / QC 20100506

Aquifer Storage Recovery (ASR) is a recently developed (circa 1970) method (in the U.S.A.) to reduce groundwater-pumping stresses by injecting treated wastewater or surface water during periods of low demand into an aquifer followed by its recovery during periods of high demand. This method has been successfully implemented in numerous locations across the U.S.A. and worldwide, mainly due to the cost savings provided by the use of an unlimited reservoir (aquifer) in which to store water compared to the costs to construct surface impoundments and the inherent problems with storing such water for extended periods of time under evaporative atmospheric conditions. "This study describes the use of a highly discretized, three-dimensional, variable-density, numerical model (SEAWAT 2000) that incorporates the vertical variation of hydraulic conductivities, measured foot by foot, from a continuous core collected from the upper Floridan aquifer in southwest Florida, to evaluate the effects of small-scale heterogeneities on a hypothetical ASR system well. In order to compare these effects to the more general case in which average hydraulic parameters are used to characterize flow zones, a model is constructed with average parameters taken from the heterogeneous case. This study attempts to determine whether aquifer heterogeneities influence the performance of ASR systems, compared to assumed homogeneous conditions, by quantifying differences in recovery efficiency, horizontal and vertical flow due to advection and dispersion, plume dimensions, and storage periods. The results of this study indicate that 1) the geometry of the injectate plume under homogeneous and heterogeneous conditions differ significantly; 2) background formation total dissolved solids (TDS) concentrations significantly control the quantity of potable water available for recovery; 3) dispersion exhibits a strong control on vertical mixing; 4) multiple injection cycles are required to generate a plume of potable water for long term storage; and 5) the percent recoveries under homogeneous and heterogeneous conditions are generally similar only in low-salinity background concentrations, due to the absence of the effects of buoyancy. Although the percent recoveries of the systems modeled are similar, the success of an ASR well is strongly controlled by the existence of heterogeneities, which essentially determine the degree of horizontal and vertical mixing of the injectate with formation waters. Heterogeneities result in varying groundwater and mass transport paths during injection and recovery periods. Presumably these variations would need to be considered when evaluating potential variations in groundwater quality due to mixing between formation and injected water. Understanding potential variations in groundwater quality and treatment alternatives due to the presence of ASR-associated geochemical conditions, e.g., elevated arsenic concentrations, may also be improved with a detailed heterogeneous numerical model.

The purpose of this study is to fill the gap in research about women in Venezuela by investigating the determinants of their labor force participation between 1995 and 1998. The Central Office of Statistics and Information in Venezuela provides cross-sectional data collected semiannually about individual, demographic, socio-economic and geographical characteristics of individuals living in Venezuela during this period. This study uses binomial and multinomial logit models to test a number of hypotheses. First, the full sample of women between 15 and 60 years old is used to investigate the importance of individual, demographic, socioeconomic, and geographical characteristics in the labor force participation decision, also controlling for a time trend. The same decision is also analyzed for three subsamples: married women, single women, and women heads of household. Comparisons are made between each subsample and the full sample, and also among the different subsamples. Next, multinomial regressions using the same explanatory variables are performed to examine labor market behavior when there is a three-way choice: whether to participate in the formal sector, the informal sector or not to participate in the labor market at all. The multinomial regressions are also performed on the three subsamples as well as on the full sample. Again comparisons are made between each subsample and the full sample and also among the three subsamples. The results of these analyses show considerable differences in motivating factors among the three groups. The conclusion that must be drawn from this research is that one cannot generalize about the women's labor force participation just by studying the behavior of women in the aggregate. The relative importance of motivating factors depends strongly on the specific subsample to which a woman belongs, a fact unrevealed by previous empirical work. The more detailed analyses produced by this dissertation provide deeper understanding of the labor force participation of Venezuelan women. This information will make a valuable contribution to policy-makers who seek to encourage the important economic contribution of women to this previously under-studied labor market.

During the statehood process, the institute of the district heads is an essential part of the administrative state rule system that helps to realize its policy in the whole country. This institute was established in 1918. During the interwar the rights and duties of the district heads were mostly regulated by the circular note of the secretary Home Office 17, December 1918 “Provisional rights and duties of the district heads”, legislation of the local governments, other right’s acts which gave them the vast rights. During the whole 1918-1940 lifetime of the Republic of Lithuanian the institute of the district heads was the intermediate between the central Executive Branch of the country and the autonomous bodies. The heads of the districts qualified for a care and kept in check the small rural districts, district municipalities’ work and their resolutions. Since 1924 the district heads worked at the same time and as district board’s chairpersons, so they took right to rule district municipalities. As the secretary of the Home Office chose the district heads, so this enabled the central government to have its representative in the districts that were loyal and reliant. The district heads implemented the authoritarian policy of the central government at the locality, prevented the tendency of the democratic development in the self-government. It was obviously after the 1926 coup d’etat. Since 1931 the heads of districts were enabled to administer a supervision of the small... [to full text]

Although it is acknowledged in the Southern African literature that children living in conditions of poverty have always assumed more household responsibilities, the AIDS epidemic has exacerbated this and significantly changed the nature of childhood as an increasing number of children face life without parents. The study sought to gain insight into the experiential lives of six “child” heads of households and their siblings and to explore, in particular, how they construct their sense of self and family. For the purposes of the study a child-headed household was deemed a household in which a child of 18 or under or still in school was the household head in the absence of any other dependable, permanent adult figure. The study used a narrative approach and thematic analysis and the results emerging from the children's accounts of themselves were focused around the core themes of adult responsibility in the absence of adult status and relationships with adults in the extended family and wider community. The idea of children or adolescents competently running households, taking responsibility for themselves and their futures and adopting a more democratic and shared means of decision making, further challenges conventional conceptions of the „borders‟ between childhood and adulthood and family structure that have been contested and shifting through history. However, being on the front line of social change comes at a cost. Challenging society's popular understanding of children as passive, dependent and innocent positions these young people outside of the norm and what they report is that they feel alone, unheard and victimised. The findings are discussed within the context of Burman's critique of psychology's traditional theoretical notions of universal and innately driven development and a re-conceptualisation of children‟s experiences in terms of the context in which they live, and Crossley's perspective on narrative which emphasises agency grounded within cultural forms of sense-making. A new way of discussing these unconventionally structured families is also presented through the reconfiguration of relationships between family members, recognising connections that span generations and across different household spaces. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2010.

Housing typologies based on the traditional family no longer satisfy the needs of the majority of households. Woman-led families are impeded in their search for appropriate housing by their low wages and family responsibilities, compounded by the blindness of housing-policy makers to their existence. Historical models of collective dwellings are steeped in the ideology of the period and yield few direct practical solutions to the current dilemma. The richness of this housing, however, which evolved during a time of dramatic social change underscores the blandness of current housing solutions. Feminists insist that housing and urban design solutions should challenge the gender defined roles of "homemaker" and "childcare giver" and the restricted mobility of women in cities and suburbs. The endorsement of new housing typologies must be translated into their realisation and subsequent analysis.
