「奢侈平民化」帶動奢侈品牌年年高成長的業績，卻迫使品牌必須面對截然不同的消費者態度與品味。品牌欲持續保有強勢地位，必須了解奢侈在消費者心目中的意義以及消費者如何評估奢侈品牌。因此，本研究欲探討台灣精品消費者認知中構成品牌奢侈的因素，建構衡量品牌奢侈之量表，並以量表探討消費者購買經驗對奢侈認知之影響，及分析個別品牌的現況及優劣勢，研擬具體的競爭策略方向。 本研究選取五個奢侈品牌作為分析標的，進行實證研究，期望達到下列研究目的： (1)驗證品牌奢侈量表，建立評估奢侈品牌的管理工具； (2)探討不同奢侈品牌購買經驗之消費者對各品牌奢侈認知的差異性； (3)探討各奢侈品牌在消費者心目中的知覺定位，擬定未來的策略方向。 依本研究之目的，擬定研究架構及確立抽樣設計，並發放問卷收集消費者資訊。之後以二階驗證性因素分析檢驗品牌奢侈量表模式品質；再利用量表探討不同購買經驗對奢侈認知的影響；最後則以多元尺度分析進行知覺定位分析，經實證分析得到以下研究發現： (1)品牌奢侈包含知覺炫耀性、知覺獨特性、知覺品質、知覺享樂價值與知覺延伸自我等五個構面，其影響力依序排列為知覺享樂價值>知覺延伸自我>知覺獨特性>知覺炫耀性>知覺品質。 (2)台灣地區消費者於購買奢侈品牌之產品後，對品牌奢侈程度的認知無明顯地降低，對品牌的奢侈評價與無購買經驗者沒有顯著差異。 (3)各奢侈品牌的改善重點主要包括知覺品質、知覺享樂價值以及知覺獨特性等三項，其中知覺品質為市場最重要之關鍵因素。 根據實證分析之結果，衍生出許多的策略涵意，包括掌握關鍵因素、規劃競爭策略以及未來發展方向等，可以作為奢侈品牌改善或塑造奢侈形象及規劃策略方向的參考依據。 / “Luxury Democratization” brings great growth to the luxury goods market, but also forced these brands to confront consumers with different attitudes and tastes. As a result, it is critical for luxury brand managers to understand consumer’s perception of brand luxury in order to maintain the brands’ luxury image. This research focused on the confirmation of Brand Luxury Scale to understand Taiwanese cousumers’ perception of brand luxury. Based on the Scale, the influence of purchase experience to luxury perception was tested, and the competitive advantages of five luxury brands were analyzed. Competitive strategies of each brand were futher developed. Research was conducted by using five luxury brands and expected to achieve the following research purposes: (1)Confirm the Brand Luxury Scale to establish a managerial tool for brand luxuriousness evaluation; (2)Use the Brand Luxury Scale to evaluate the influence of purchase experience to luxury perception; (3)Use the Brand Luxury Scale to evaluate consumers’ perception of different brands, and seek to imply different competitive strategies for these brands base on the analysis. After the conduction of research framework, sampling design and data collection, Secondary Comfirmatory Factor Analysis was used to confirm the structure of Brand Luxury Scale. 1-Way ANOVA was used to test the influence of purchase experience to luxury perception. Finally, Multi-Dimensional Scaling Analysis was implied to analyze the perceptual position of each brand. The research findings are as below: (1)Brand Luxury is constructed by five dimensions: Perceived Conspicuousness, Perceived Uniqueness, Perceived Quality, Perceived Hedonic, and Perceived Extended-self. The order of dimensional influence is Perceived Hedonic> Perceived Extended -self> Perceived Uniqueness> Perceived Conspicuousness> Perceived Quality. (2)No difference in brand luxury perception between different purchasing experience consumers was found, showing that the perceptions of brand luxury of Taiwanese consumers’ remain unchanged after purchase. (3)Perceived Quality is the most important dimension of all, and the five luxury brands tested needs to improve in dimensions of Perceived Quality, Perceived Hedonic, and Perceived Uniqueness. According to the results, several managerial implications were derived, including key factors in marketing and competitive strategy of each brand. These strategies can be used in improving the performance of perceived luxuriousness of brand, enhancing brand luxury image, and planning the direction of luxury marketing and brand strategy.

Over the last decades, there has been considerable attention in the accurate mathematical modeling and numerical simulations of free surface wave propagation in near-shore environments. A physical correct description of the large scale phenomena, which take place in the shallow water region, must account for strong nonlinear and dispersive effects, along with the interaction with complex topographies. First, a study on the behavior in nonlinear regime of different Boussinesq-type models is proposed, showing the advantage of using fully-nonlinear models with respect to weakly-nonlinear and weakly dispersive models (commonly employed). Secondly, a new flexible strategy for solving the fully-nonlinear and weakly-dispersive Green-Naghdi equations is presented, which allows to enhance an existing shallow water code by simply adding an algebraic term to the momentum balance and is particularly adapted for the use of hybrid techniques for wave breaking. Moreover, the first discretization of the Green-Naghdi equations on unstructured meshes is proposed via hybrid finite volume/ finite element schemes. Finally, the models and the methods developed in the thesis are deployed to study the physical problem of bore formation in convergent alluvial estuary, providing the first characterization of natural estuaries in terms of bore inception. / Ces dernières décennies, une attention particulière a été portée sur la modélisation mathématique et la simulation numérique de la propagation de vagues en environnements côtiers. Une description physiquement correcte des phénomènes à grande échelle, qui apparaissent dans les régions d'eau peu profonde, doit prendre en compte de forts effets non-linéaires et dispersifs, ainsi que l'interaction avec des bathymétries complexes. Dans un premier temps, une étude du comportement en régime non linéaire de différents modèles de type Boussinesq est proposée, démontrant l'avantage d'utiliser des modèles fortement non-linéaires par rapport à des modèles faiblement non-linéaires et faiblement dispersifs (couramment utilisés). Ensuite, une nouvelle approche flexible pour résoudre les équations fortement non-linéaires et faiblement dispersives de Green-Naghdi est présentée. Cette stratégie permet d'améliorer un code "shallow water" existant par le simple ajout d'un terme algébrique dans l'équation du moment et est particulièrement adapté à l'utilisation de techniques hybrides pour le déferlement des vagues. De plus, la première discrétisation des équations de Green-Naghdi sur maillage non structuré est proposée via des schémas hybrides Volume Fini/Élément Fini. Finalement, les modèles et méthodes développés dans la thèse sont appliqués à l'étude du problème physique de la formation du mascaret dans des estuaires convergents et alluviaux. Cela a amené à la première caractérisation d'estuaire naturel en terme d'apparition de mascaret.

The diploma work was based on the evaluation of dental casts of patients with bilateral cleft lip and palate (BCLP) with a mean age of 10. Patients consist of two groups, patients without defect in speech and with speech impairment (palatolaly). Palatolalies in the literature are primarily associated with velopharyngeal insufficiency. The study tested the working hypothesis that in the failure of speech is involved a different, specific in some way, palatal shape. Dental casts were scanned using a laser scanner and analyzed by 3-D geometric morphometry and multivariate statistics: principal component analysis (PCA), linear regression analysis and finite element analysis (FESA). Using linear regression it was found that the shape of the palate is affected in younger individuals by age, and so had to be 5 patients excluded for further analysis. Patients with palatolaly have lower variability the palatal shape than patients without palatolalie, so their palates are similar to each other and have a specific shape. Palates are wider and lower than in individuals without speech disorder and they have a characteristic deepening behind the anterior part of the palate. We assume that these features in palate morphology primarily the lower arch and the substantial deepening are most likely to affect the...
