The research question addressed by this thesis is: To what degree the results of the statistical analysis will corroborate the main theoretical assumptions of the proposed theoretical model of new authentic transformatory cultural tourism experience as transmodern phenomenon of equality of two Cartesian levels of reality, material (objective authenticity) and experiential (constructive authenticity) in informing the intrapersonal existential authenticity as outcome transformatory tourist experience. The main reason for undertaking this study is to resolve the evident crisis of postmodern authenticity discourse arising from a failure of postmodern theoretical framework to integrate three social authenticity theories into a coherent authenticity discourse. The research design adopted in the study is theory-testing theory-building paradigm which incorporates both deductive and inductive logic and was applied in three successive phases. In the first phase the new theoretical model of transformatory cultural tourism experience was proposed, underpinned by transmodern flat ontology and philosophy of the Speculative Realism. In the second phase the main theoretical assumptions of equal contribution of objective and constructive authenticity as independent variables in informing the transformatory experience as dependent variable were empirically tested by standard multiple regression analysis. In the last deductive phase the results of all empirical tests were inferred onto initial theoretical assumptions of the original model and new modified model of transformatory cultural tourism experience has been proposed with an addition of two newly identified transmodern experiential constructs, epistemological and ontological authenticity. For a primary data collection the instrument was a self-administered questionnaire and the sampling strategy was a non-probability sampling. The data was collected during the period 01st and 18 April 2011 at two sites, Constitution Hill and Hector Peterson Memorial in Johannesburg. The sample size from two sites was N=406. The scales of measurements were already developed in the earlier questionnaire and the confirmatory factor analysis was used to confirm the variables contained in each factor, namely objective and constructive authenticity as independent variables and transformatory experience as the dependent variable. The results of a standard multiple regression analysis confirmed the importance of the model as independent variables explained 30.7% of the variances (R2=.307) in the model. An unexpected result was that objective authenticity explained 34.5% of the variance in the model (β = .345) which is significantly higher than 30.5% of variance explained by constructive authenticity (β = .305). The results of standard multiple regression analysis confirmed the main theoretical assumption of the model of equality of material and experiential levels of Cartesian duality in informing the new transformatory experience regarded as a transmodern phenomenon. The standard, stepwise and hierarchical multiple regression tests were further conducted to establish if any moderating variables should be added into the original model containing two independent variables. The tests included five demographic variables (gender, place of residence, connection with culture, and two items of education (pre-tertiary education and Bachelors degree) and none of the variables explained a level of variability which warranted their inclusion into the model. Consequently, the results of the retests of the model did not change its initial conceptualisation. Finally, the t-test and Mann-Whitney U tests identified a significant difference between the two groups in the level of authenticity of their experience derived from two sites. A group having stronger inclination for authenticity is identified as Cultural Creatives, who are known as the forerunners of transmodernism. Based on the results of all statistical tests the final model was modified to reflect the important theoretical findings pertaining to two new types of transmodern authenticity. Epistemological authenticity denotes combined effects of objective and constructive authenticity in feeding the ontological authenticity of transformatory experience. The ontological authenticity is further identified as a confirmation of authentic-self which is required by Cultural Creatives. With proposition of new modified model the theory-testing theory-building research design came to its conclusion. The importance of research findings presented in this study lies not only in resolving the current crises of authenticity discourse in tourism but in the proposed New theoretical and conceptual model of transformatory cultural tourism experience underpinned by objective ·and constructive authenticity which will open a whole new field in tourism research arising from new transmodern experiential paradigm. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

L'introduction (section 1) introduit la probl´ematique g´en´erale de la th`ese: la mesure quantitative des propri´et´es g´eom´etriques des vari´et´es alg´ebriques et particuli`erement leur triangulation. La section 2 explique une proc´edure de subdivision rapide et certifi´ee triangulant une courbe alg´ebrique r´eelle plane. Les outils math´ematiques sont le degr´e topologique, la base des polynˆomes de Bernstein. La section 3 est une copie d'un article expliquant la m´ethode de subdivision pour les surfaces lisses dans Rn. Elle comporte une analyse de complexit´e. La section 4 pr´esente une version quantitative du th´eor`eme de trivialit´e topologique de Thom-Mather pour des applications semi-alg´ebriques non lisses. Il en d´ecoule: une version “m´etriquement stable” du th´eor`eme de structure conique local et de l'existence d'un “tube de Milnor” autour des strates. Un algorithme de triangulation utilisant des partitions de Vorono˘i (sa mise en place n'est pas compl`ete car l'estimation effective de la transversalit´e n'est pas compl`etement trait´e). La section 5 est une copie d'un article paru en 2008 sur une m´ethode de balayage pour calculer la topologie d'une surface singuli`ere de R3. Elle repose sur l'utilisation du th´eor`eme de Thom-Mather. La section 6 pr´esente une borne sur le nombre g´en´erique de composantes connexes dans une section d'un germe analytique r´eel par un espace affine en fonction de la multiplicit´e et de la dimension de l'espace. La borne ne s'applique pas toujours et des contre-examples sont donn´es.

Dans le cadre d'intersections de classes non quasi-analytiques à croissance modérée, J. Chaumat et A. M. Chollet ont démontré, notamment, un théorème d'extension de Whitney, pour des jets définis sur un compact et un théorème de Lojasiewicz sur la régulière situation. Ces intersections sont contenues dans l'intersection des classes de Gevrey. On établit ici un théorème d'extension dans une famille d'intersections de classes plus vaste, en ce sens que, tout jet de Whitney appartient à l'une des intersections considérées. Ensuite, en utilisant une méthode d'interpolation à l'aide de polynômes de Lagrange, due à W. Pawlucki et W. Plesniak, on établit aussi un théorème d'extension linéaire pour les jets définis sur des compacts ayant la propriété de Markov. Ces extensions de jets peuvent être choisies réelles analytiques sur le complémentaire du compact. Ces résultats sont complétés par trois exemples de situations pour lesquelles il n'existe pas d'opérateur d'extension linéaire continu. Enfin, on démontre un théorème de Lojasiewicz. Tous ces résultats sont étroitement reliés aux théorèmes classiques de la théorie des fonctions infiniment dérivables.

The main objective of this paper was to investigate runoff changes in the catchment Ala-Arca, Alamaedin and Kara-Balta in Kyrgyzstan, as well as change in climate conditions from available stations in the area. The runoff, precipitation, and temperature series were subjected to monthly, seasonal and annual analyses based on available data. Both absolute and relative data homogeneity were verified using statistical tests such as the Mann-Whitney-Pettit test, the SNHT test, and the WiIlcoxon's two- sample test for absolute homogeneity, and the Alexandersson's test for relative homogeneity. The Mann-Kendall test was used to determine the trend in each serie. There were inhomogeneities found in a number of runoff data. In most cases, the changes of rivers Ala-Arca and Kara-Balta were recorded in 1987. Compare to Ala-Arca and Kara-Balta, the changes of river Alamedin were recorded 3 years later, in 1990. There was a positive trend development by the rivers with the glacial-snow regime. However, there was no statistically significant trend for the entire time series. Key words: runoff change, precipitation, temperature, glacial-snow regime, snow-glacial regime, homogenization, Mann-Whitney-Pettit test, trend, Mann-Kendall test, glaciation, Kyrgyzstan, Tien- Shan

This dissertation explores how the mythological heroines from Ovid‘s Heroides and Metamorphoses were cataloged, conflated, reconceived, and recontextualized in vernacular literature; in so doing, it joins considerations of voice, authority, and gender with reflections on Tudor technologies of textual reproduction and ideas about the book. In the late medieval and Renaissance eras, Ovid‘s poetry stimulated the imaginations of authors ranging from Geoffrey Chaucer and John Gower to Isabella Whitney, William Shakespeare, and Michael Drayton. Ovid‘s characteristic bookishness—his interest in textual revision and his thematization of the physicality and malleability of art in its physical environments—was not lost upon these postclassical interpreters who engaged with his polysemous cast of female characters. His numerous English protégés replicated and expanded Ovid‘s metatextual concerns by reading and rewriting his metamorphic poetry in light of the metaphors through which they understood both established networks of scribal dissemination and emergent modes of printed book production. My study of Greco-Roman tradition and English bibliofictions (or fictive representations of books, their life cycles, and the communication circuits in which they operate) melds literary analysis with the theoretical concerns of book history by focusing on intersections and interactions between physical, metaphorical, and imaginary books. I posit the Tudor book as a site of complex cultural and literary negotiations between real and inscribed, historical and fictional readers, editors, commentators, and authors, and, as my discussion unfolds, I combine bibliographical, historical, and literary perspectives as a means to understanding both the reception of Ovidian poetry in English literature and Ovid‘s place in the history of books. This dissertation thus contributes to a growing body of book history criticism while also modeling a bibliographically enriched approach to the study of late medieval and Renaissance intertextuality.

Speech processing methods were studied to calculate parameters of pacient with Parkinon's disease. Main focus of this work is to examine diadochokinetic (DDK) tests. Algorithm for parameters extraction was proposed. It works in more parts. DC is removed from speech signal, preemphasis aplicated. Envelope of input signal is calculated, peaks of syllables are detected. Parameters and statistical results of Mann-Whitney U~test are calculated from detected peaks. Proposed algorithm is implemented in Matlab.
