「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.

Text in Afrikaans / Dit is belangrik vir bemarkingsorganisasies om die effek van bemarkingsaksies en meer spesifiek reklame te meet van wee eskalerende koste-oorwegings. Wat die rol van reklame in verbruikersgedrag betref, is die belewing van of houding-teenoor-reklame konsepte van sentrale be lang. Aangesien die term bel ewing meer beskrywend is oor die impak wat advertensies op verbruikers het word hierdie term algemeen gebruik. Hierdie studie ondersoek die konsep advertensiewaardering en ontleed die invloed daarvan op advertensiebelewing. Die kyker-responsprofiel soos deur Schlinger (1979) ontwikkel, word algemeen gebruik om televisiekykers se houding teenoor televisie-advertensies te meet. Hierdie studie poog om die toepaslikheid en geldigheid van die kyker-responsprofiel onder Suid-Afrikaanse televisiekykers te ondersoek. Die navorsingsmetode het uit twee fases bestaan. Die eerste fase was meer kwalitatief van aard, en ondersoek kykers se kognitiewe struktuur van houding teenoor televisie-advertensies. Die teoretiese uitgangspunt tydens hierdie fase is persoonlike-konstrukteorie. Repertoriumrooster onderhoude is met 50 volwasse televisiekykers (ouer as 16 jaar) uit verskillende taalgroepe gevoer. Daar is bevind dat kykers gemiddeld ses konstrukte gebruik ten einde die waarderingsvlak van advertensies te bepaal. 313 Konstrukte is in totaal deur die 50 respondente ontlok. Hierdie konstruke is deur individuele roosterontledings en ooreenkomsanalise tot 'n aantal konstrukgroepe gereduseer. Beskrywings van konstrukgroepe is aan die hand van n literatuurnavorsing gedoen. Die konstrukgroepe (tevredenheid, vermaaklikheid, interessantheid, sosialiteit, duidelikheid, realiteit, tempo en emosialiteit) toon 'n mate van ooreenstemming met die sewe Schlinger basisfaktore. Die onderliggende indiwiduele konstrukte wat vermaaklikheid, sosialiteit tempo en interessantheid beskryf, toon hoe korrelasies met waardering wat daarop dui dat waardering meer as net vermaaklikheid behels. Fase twee was meer kwantitatief van aard en het die ontleding van 382 kykerresponsprofiele behels. 'n Faktorontleding van die 32 Schlinger-items het sewe basisfaktore tot gevolg. Die eerste vyf faktore (vermaaklikheid, verwarring, relevante nuus, handelsmerkversterking en empatie) beskik oor soortgelyke faktorladings as faktorontledings wat in die V.S.A. gedoen is. Hierdie bevinding dui daarop dat die affektiewe belewingstruktuur van televisiekykers in Suid-Afrika grootliks dieselfde is as kykers in die Verenigde State. Die ander twee faktore (familiariteit en vervreemding) se ladings verskil van die in die Verenigde State maar hierdie verskille kan gegewe die aard van die advertensies ( bestaande en nuwe advertensiekonsepte) en die kruiskulturele aard van Suid-Afrikaanse kykers verklaar word. Die Schlingeritems is statisties beskryf en ontleed deur die rol wat die tipe advertensie (bestaande versus nuwe), produk-kategorie en kulturele teikenmark speel in waardering van advertensies te ondersoeK. Nuwe konsepte is geneig om meer vermaaklik en relevant te wees. Zulu, Sotho en Xhose kykers is geneig om advertensies as meer positief te beleef. Kosmetika en medisinale-, korporatiewe- en motoradvertensies is verder minder vermaaklik as voedsel en handelsadvertensies. Die Schlingeritems wat advertensiewaardering die beste beskryf en voorspel is bepaal deur bondelontledings en meerdimensionele verskaling. Daar is gevind dat waardering die mate waartoe 'n advertensie aan die vermaaklikheids, empatie en relevante nuus doelwitte voldoen sonder om verwarrend, vervreemdend of oorbekend te wees. Dit wil voorkom of daar twee dimensies bestaan wat die meeste variansie in Schlingeritems verklaar naamlik waardering (positief of negatief) en relevansie. Bondelontleding dui verder daarop dat 'n positiewe persepsie van 'n geadverteerde handelsmerk kykers ontvanklik maak om meer van 'n advertensie te hou of te waardeer. / It is important that, given escalating cost considerations, marketing organisations determine the effect that their marketing efforts have. With regard to the role of advertising m consumer behaviour, attitude towards commercials is of utmost importance. This study examined the liking of television advertisement concept and analyses the effect of this concept on attitude towards television advertising. The viewer response profile as developed by Schlinger (1979) is commonly used to evaluate viewer's attitude towards television commercials. This study attempted to investigate the applicability and validity of this instrument amongst South African television viewers. The study consisted of two phases. Phase one was more qualitative in nature and investigated the viewer's cognitive structure of attitude towards television commercials. The theoretical approach used during this phase was personal construct theory. It was found that viewers on average use six constructs to evaluate whether they like or dislike commercials. 313 Constructs were elicited and based on individual grid analyses and correspondence analysis a reduced number of construct groups was identified. These construct groups ( contentness, entertainment, interesting, sociality, clearness, reality, emotionality, and tempo) show a measure of similarity to the seven Schlinger factors or dimensions. The individual constructs, which make up entertainment, sociality, emotionality, tempo and interesting, show high levels of correlation with advertisement liking. This finding suggests that advertisement liking involve more than pure entertainment. Phase two was more quantitative and consisted of analysing 382 viewer response profiles. A factor analysis of the 32 items, which make up the viewer response profile, resulted in seven factors. The first five factors (entertainment, confusion, relevant news, brand reinforcement and empathy) show similar factor loading to factor analytical studies done in the United State of America. The other two factors (familiarity and alienation) show different loading to the United States of America study but these differences could be explained given the nature of commercials tested (existing commercials and new commercial concepts) and the cross cultural nature of South African viewers. The Schlinger items were analysed in greater detail by investigating the role which type of commercial (existing versus new), product category and cultural target market play in liking of commercials. New concepts are proven to be more entertaining, creative and relevant. Zulu and Sotho viewers are likely to be more positively disposed towards television commercials while cosmetic, medicine, corporate and motor vehicle commercials are less entertaining than food and commercial commercials. Those Schlinger items, which best describe and predict commercials liking were determined by using cluster and multi dimensional scaling techniques. It is apparent from this analysis that likability is the extent to which the objective of entertainment, empathy or relevant news is achieved without confusion, alienation or familiarity. Cluster analysis furthermore suggests that a positive perception of an advertised brand predispose viewers to higher levels of commercial liking. Multi dimensional scaling suggest two dimensions explaining most of the Schlinger factor variance namely liking (positive of negative) and relevance. / Industrial and Organisational Psychology / D.

La Physique des Hautes Densités d’Énergies (HEDP) est caractérisée par desécoulements multi-matériaux fortement compressibles. Le domaine contenant l’écoulementsubit de grandes variations de taille et est le siège d’ondes de chocs et dedétente intenses. La représentation Lagrangienne est bien adaptée à la descriptionde ce type d’écoulements. Elle permet en effet une très bonne description deschocs ainsi qu’un suivit naturel des interfaces multi-matériaux et des surfaces libres.En particulier, les schémas Volumes Finis centrés Lagrangiens GLACE (GodunovtypeLAgrangian scheme Conservative for total Energy) et EUCCLHYD (ExplicitUnstructured Cell-Centered Lagrangian HYDrodynamics) ont prouvé leur efficacitépour la modélisation des équations de la dynamique des gaz ainsi que de l’élastoplasticité.Le travail de cette thèse s’inscrit dans la continuité des travaux de Maireet Nkonga [JCP, 2009] pour la modélisation de l’hydrodynamique et des travauxde Kluth et Després [JCP, 2010] pour l’hyperelasticité. Plus précisément, cettethèse propose le développement de méthodes robustes et précises pour l’extension3D du schéma EUCCLHYD avec une extension d’ordre deux basée sur les méthodesMUSCL (Monotonic Upstream-centered Scheme for Conservation Laws) et GRP(Generalized Riemann Problem). Une attention particulière est portée sur la préservationdes symétries et la monotonie des solutions. La robustesse et la précision duschéma seront validées sur de nombreux cas tests Lagrangiens dont l’extension 3Dest particulièrement difficile. / High Energy Density Physics (HEDP) flows are multi-material flows characterizedby strong shock waves and large changes in the domain shape due to rarefactionwaves. Numerical schemes based on the Lagrangian formalism are good candidatesto model this kind of flows since the computational grid follows the fluid motion.This provides accurate results around the shocks as well as a natural tracking ofmulti-material interfaces and free-surfaces. In particular, cell-centered Finite VolumeLagrangian schemes such as GLACE (Godunov-type LAgrangian scheme Conservativefor total Energy) and EUCCLHYD (Explicit Unstructured Cell-CenteredLagrangian HYDrodynamics) provide good results on both the modeling of gas dynamicsand elastic-plastic equations. The work produced during this PhD thesisis in continuity with the work of Maire and Nkonga [JCP, 2009] for the hydrodynamicpart and the work of Kluth and Després [JCP, 2010] for the hyperelasticitypart. More precisely, the aim of this thesis is to develop robust and accurate methodsfor the 3D extension of the EUCCLHYD scheme with a second-order extensionbased on MUSCL (Monotonic Upstream-centered Scheme for Conservation Laws)and GRP (Generalized Riemann Problem) procedures. A particular care is taken onthe preservation of symmetries and the monotonicity of the solutions. The schemerobustness and accuracy are assessed on numerous Lagrangian test cases for whichthe 3D extensions are very challenging.

Les travaux de cette thèse concernent la conception d’outils algorithmiques permettant l’intégration de connaissances a priori dans la reconstruction de signaux parcimonieux. Le but étant principalement d’améliorer la reconstruction de ces signaux à partir d’un ensemble de mesures largement inférieur à ce que prédit le célèbre théorème de Shannon-Nyquist. Dans une première partie nous proposons, dans le contexte de la nouvelle théorie du « compressed sensing » (CS), l’algorithme NNOMP (Neural Network Orthogonal Matching Pursuit), qui est une version modifiée de l’algorithme OMP dans laquelle nous avons remplacé l'étape de corrélation par un réseau de neurones avec un entraînement adapté. Le but est de mieux reconstruire les signaux parcimonieux possédant des structures supplémentaires, i.e. appartenant à un modèle de signaux parcimonieux particulier. Pour la validation expérimentale de NNOMP, trois modèles simulés de signaux parcimonieux à structures supplémentaires ont été considérés, ainsi qu’une application pratique dans un arrangement similaire au « single pixel imaging ». Dans une deuxième partie, nous proposons une nouvelle méthode de sous-échantillonnage en spectroscopie RMN multidimensionnelle (y compris l’imagerie spectroscopique RMN), lorsque les spectres des acquisitions correspondantes de dimension inférieure, e.g. monodimensionnelle, sont intrinsèquement parcimonieux. Dans cette méthode, on modélise le processus d’acquisition des données et de reconstruction des spectres multidimensionnels, par un système d’équations linéaires. On utilise ensuite des connaissances a priori, sur les emplacements non nuls dans les spectres multidimensionnels, pour enlever la sous-détermination induite par le sous échantillonnage des données. Ces connaissances a priori sont obtenues à partir des spectres des acquisitions de dimension inférieure, e.g. monodimensionnelle. La possibilité de sous-échantillonnage est d’autant plus importante que ces spectres monodimensionnels sont parcimonieux. La méthode proposée est évaluée sur des données synthétiques et expérimentales in vitro et in vivo. / The work of this thesis concerns the proposal of algorithms for the integration of prior knowledge in the reconstruction of sparse signals. The purpose is mainly to improve the reconstruction of these signals from a set of measurements well below what is requested by the famous theorem of Shannon-Nyquist. In the first part we propose, in the context of the new theory of "compressed sensing" (CS), the algorithm NNOMP (Neural Network Orthogonal Matching Pursuit), which is a modified version of the algorithm OMP in which we replaced the correlation step by a properly trained neural network. The goal is to better reconstruct sparse signals with additional structures, i.e. belonging to a particular model of sparse signals. For the experimental validation of NNOMP three simulated models of sparse signals with additional structures were considered and a practical application in an arrangement similar to the “single pixel imaging”. In the second part, we propose a new method for under sampling in multidimensional NMR spectroscopy (including NMR spectroscopic imaging), when the corresponding spectra of lower dimensional acquisitions, e.g. one-dimensional, are intrinsically sparse. In this method, we model the whole process of data acquisition and reconstruction of multidimensional spectra, by a system of linear equations. We then use a priori knowledge about the non-zero locations in multidimensional spectra, to remove the under-determinacy induced by data under sampling. This a priori knowledge is obtained from the lower dimensional acquisition spectra, e.g. one-dimensional. The possibility of under sampling increases proportionally with the sparsity of these one dimensional spectra. The proposed method is evaluated on synthetic, experimental in vitro and in vivo data.

True market prices of real estates, unlike bid prices, are often hard to reach. Nevertheless, this information is necessary for many direct and indirect real estate market subjects, especially for valuation purposes. Therefore the bid prices of concrete real estates are often used, but they are not generally equivalent market prices. And so it´s necessary to find some way to convert bid prices to market prices. This dissertation thesis shows definite approach to this issue. Market price and bid price rate is estimated by multi-dimensional linear regression model and non-linear estimations of simple regression. Multi-dimensional linear regression model estimates the values of this rate from other variables, like supply duration, price line according to localities and other. Non-linear estimations of regression function were used for the trend bid and market price modelling in dependence on number of the population in various localities.

Il y a une préoccupation croissante parmi les experts en ce qui a trait à la polarisation idéologique des élites politiques en raison de son potentiel à pousser les masses vers les extrêmes et à exacerber la polarisation affective. Ces préoccupations sont-elles justifiées? Cette thèse comprend trois articles distincts mais liés, chacun contribuant à apporter une réponse à cette question. Le premier chapitre empirique (chapitre 2) examine si la polarisation idéologique des élites a augmenté au fil du temps en Europe de l’Ouest. Pour ce faire, ce chapitre se concentre sur la polarisation des partis politiques (c’est-à-dire la polarisation idéologique des élites) sur trois dimensions (économique, sociale et sur la question de l’intégration européenne) simultanément, car la transformation post-industrielle de l’espace politique européen a entraîné une politique multidimensionnelle qui n’est pas toujours alignée avec l’une et l’autre. De plus, le chapitre 2 compare ces tendances à celles fondées sur la dimension traditionnelle gauche-droite. En utilisant les jugements d’experts du Chapel Hill Expert Survey comme indicateur des positions des partis, la polarisation des parties est mesurée en fonction de leur dispersion moyenne des partis par rapport au centre relatif du système politique. Ce chapitre montre une tendance vers une plus grande polarisation des partis sur la dimension gauche-droite ainsi que sur les dimensions économique et sociale, mais pas sur la dimension d’integration européenne. Les partis prennent de plus en plus de positions distinctes sur les questions économique et sociales, et le "menu" idéologique servi aux citoyens est devenu plus diversifié u fil du temps. De plus, il montre que la polarisation des partis sur les dimensions économique, sociales et d’intégration européenne est modérément corrélée à celle de la dimension gauche-droite traditionnelle, tandis que les corrélations de la polarisation des partis sur ces dimensions entre elles sont plutôt faibles. Bien que la dimension gauche-droite agisse comme une position super-thématique qui absorbe les positions des partis sur d’autres dimensions, elles ne sont pas nécessairement alignées les unes sur les autres. Ayant établi que la polarisation idéologique des élites est en hausse en Europe de l’Ouest, le deuxième chapitre empirique (chapitre 3) examine comment les masses réagissent à l’augmentation de la polarisation idéologiques des élites. Plus précisément, la question est de savoir si la polarisation idéologique des élites conduit à une polarisation idéologique des masses. En d'autres termes, lorsque des propositions de politique plus extrêmes sont disponibles pour les citoyens, adoptent-ils également des préférences de politique plus extrêmes? Ce chapitre avance que les masses se polarisent suivant deux mécanismes. En vertu de la théorie de l’identité sociale, les partisans devraient suivre leur parti et adopter une position idéologique plus extrême, tandis que les non-partisans devraient réagir à l'opposé. De plus, ce chapitre soutient que si les partisans se polarisent en fonction des changements qui surviennent à l'interieur de leur parti dépend de leur position spatiale par rapport à ce même parti sur l’échelle idéologique. Par exemple, seuls ceux qui sont parfaitement alignée avec leur parti ou plus à droite que leur parti devraient se conformer aux mouvements des élites. Ce chapitre teste ces attentes dans un cadre réel en s’appuyant sur un design quasi-expérimentale. Le chapitre exploite une augmentation subite de la polarisation idéologique de l’élite qui s’est produite lorsque le Parti travailliste au Royaume-Uni a subi une changement de position soudain avec l’élection de Jeremy Corbyn à titre de nouveau chef. À l’aide des données du British Election Study Internet Panel, ce chapitre ne trouve que des éléments de preuves limitées supportant l'hypothèse que la polarisation de l’élite entraîne une polarisation idéologique de masse : ni les partisans du Parti travailliste ni les autres partisans ne sont devenus plus polarisés à la suite du changement de position du Parti travailliste. Seule une petite minorité de partisans travaillistes situés à droite du parti ont suivi le parti en adoptant une position plus à gauche sur le plan idéologique. De plus, contrairement aux attentes, la plupart des partisans et des non-partisans ont modéré leurs positions. Ce chapitre examine les raisons potentielles de cet effet inattendu. Dans l’ensemble, ces résultats améliorent nos connaissances sur la manière dont les masses réagissent à la polarisation de l’élite et contribuent à dissiper les préoccupations des experts selon lesquelles les masses deviendraient elles-mêmes idéologiquement polarisées lorsque les partis politiques se polarisent. Le troisième chapitre empirique (chapitre 4) étend l’étude aux réactions affectives des citoyens. Les masses deviennent-elles affectivement plus polarisées lorsque la polarisation idéologique de l’élite augmente ? En se basant sur le contexte britannique, qui a connu une montée de la polarisation idéologique de l’élite en raison du virage à gauche du Parti travailliste et du conflit du Brexit en cours, ce chapitre constate qu’une augmentation de la polarisation idéologique de l’élite conduit à une polarisation affective plus élevée des masses, même parmi les partisans de l’opposition et ceux qui ne sont pas attachés à un parti (c’est-à-dire les indépendants). Les résultats montrent que l’effet de la polarisation de l’élite sur la polarisation affective des masses est davantage influencé par les sentiments envers le parti avec lequels identifient les individus que par les sentiments que ceux-ci entretiennent envers le parti opposé. Ces résultats suggèrent que la polarisation affective ne reflète pas nécessairement de l’animosité envers le parti opposé, mais peut fluctuer en raison des changements dans le niveau d’enthousiasme à l'égard de son propre parti. Ce chapitre constate également une relation causale bidirectionnelle entre la perception par des citoyens de la polarisation idéologique de l’élite et leur polarisation affective. Cela signifie que la polarisation affective est enracinée à la fois dans l’identité et l’idéologie. Les résultats suggèrent que la polarisation affective peut être tempérée dans une certaine mesure par une position modérée des partis, mais que certains niveaux de polarisation affective sont inhérents aux systems démocratiques. Les analyses présentées dans cette thèse permettent d'apporter une réponse claire mais nuancée concernant les préoccupations des experts concernant sur l’augmentation de la polarisation idéologique et ses effets potentiellement néfastes. La polarisation idéologique des élites a augmenté en Europe de l’Ouest. Cependant, l’augmentation de la polarisation idéologique des élites ne conduit pas nécessairement à une polarisation idéologique accrue des masses, bien qu’elle conduise à une polarisation affective accrue parmi les citoyens. Dans la mesure où des niveaux excessifs de polarisation affective peuvent compromettre les démocraties représentatives, il peut être raisonnable pour les experts de s’inquiéter de l’augmentation des niveaux de polarisation idéologique des élites. Cependant, si la polarisation affective ne représente pas une menace pour les démocraties représentatives et ne conduit pas au délitement du tissu social, il peut ne pas être nécessaire de s’inquiéter immédiatement de l’impact de la polarisation idéologique des élites sur ce phénomène. / There is a growing concern among experts and policymakers about the increasing elite ideological polarization due to its potential to push the masses to the extremes and exacerbate affective polarization. Are these concerns warranted? This dissertation has 3 standalone articles, each of which contributes to providing an answer to this overarching question. The first empirical chapter (Chapter 2) examines whether elite ideological polarization has increased over time in Western Europe. To do so, it focuses on party polarization (i.e., elite ideological polarization) on three dimensions (the economic, social, and European integration dimensions) simultaneously, as the post-industrialization transformation of the European political space has resulted in multi-dimensional politics that are not always aligned with each other. Additionally, it compares these trends to those based on the traditional left-right dimension. Using mean expert judgments from the Chapel Hill Expert Survey as an indicator of party positions, party polarization is measured based on the average dispersion of parties from the relative center of the political system. This chapter finds a trend towards more party polarization on the left-right, economic, and social dimensions, but not on the European integration dimension. Parties increasingly take more distinct positions from each other on economic and social issues, and the available ideological menu available to citizens has become more diverse over time. Moreover, it shows that party polarization on economic, social, and European integration dimensions moderately correlates with that on traditional left-right dimension while the correlations of party polarization on these dimensions are relatively weak. While left-right acts like a super-issue position that absorbs party positions on other dimensions, they are not necessarily aligned with each other. Having established that elite ideological polarization is on the rise in Western Europe, second empirical chapter (Chapter 3) turns to how the masses react to the increasing elite ideological polarization. Specifically, the question is whether elite ideological polarization leads to mass ideological polarization. When more extreme policy proposals are available to citizens, do they also adopt more extreme policy preferences? This chapter argues that masses become polarized through two mechanisms. Based on social identity theory, in-partisans should follow their party and adopt a more extreme ideological stance, while out-partisans should backlash and move in the opposite direction. Additionally, this chapter argues that whether in-partisans become polarized when their party does so depends on their spatial location relative to the party on the ideological scale. For example, only those who are perfectly aligned with the party or more right-wing than the party should follow the party to the left when it moves in that direction. This chapter tests these expectations in a real-world setting by relying on a quasi-experimental design. It leverages a sudden increase in elite ideological polarization that occurred when the Labour Party in the United Kingdom underwent a sudden position change when Jeremy Corbyn was elected as its new leader. Using British Election Study Internet Panel data, this chapter finds limited evidence that elite polarization leads to mass ideological polarization: Neither in-partisans nor out-partisans became more polarized following the change in the Labour Party’s position. Only a small minority of Labour partisans that were located to the right of the Labour Party followed the party by adopting a more left-wing ideological stance. Moreover, contrary to the expectations, I find that most in- and out-partisans moderated their positions. This chapter discusses the potential reasons for this unexpected effect. The third empirical chapter (Chapter 4) extends the investigation to citizens’ affective reactions. Do the masses become affectively more polarized when elite ideological polarization increases? Relying on the British context, which experienced a surge in elite ideological polarization as a result of both the leftward pivot of the Labour Party and the ongoing Brexit conflict, this chapter finds that an increase in elite ideological polarization leads to higher mass affective polarization, even among out-partisans (i.e., those who identify with the out-party) and those who lack partisan attachment (i.e., independents). The results show that the effect of elite polarization on affective mass polarization is driven more by in-party feelings than out-party feelings. These results suggest that affective polarization is not necessarily a reflection of out-party animosity, but can fluctuate due to changes in in-party enthusiasm. This chapter also finds a bidirectional causal relationship between how citizens perceive elite ideological polarization and how affectively polarized they are. This means that affective polarization is rooted both in identity and ideology. The findings suggest that affective polarization can be tamed to some extent by moderate position-taking by parties, but some levels of affective polarization are inherent in democratic systems. Coming back to whether pundits' concerns about growing ideological polarization is warranted, this dissertation provides a clear but a nuanced answer. Elite ideological polarization has increased in Western Europe. However, increasing elite ideological polarization does not necessarily lead to more ideologically polarized masses although it leads to more affectively polarized masses. To the extent that excessive levels of affective polarization can undermine representative democracies, it may be reasonable for pundits to express concern about rising levels of elite ideological polarization. However, if affective polarization does not pose a threat to representative democracies and does not hinder societal coexistence, then there may not be a need for immediate concern regarding the impact of elite ideological polarization on this phenomenon.

Zusammenfassung Das Forschungsprojekt untersucht Bekehrungsmotive von südsudanesischen Migranten, die in einem islamischen Kontext leben. Dazu wird zunächst das biblisch-theologische Bekeh¬rungsverständnis erhoben und im Kontext seiner kirchengeschichtlichen Entwicklung dar¬gestellt. Da jede Bekehrung ein multidimensionaler Prozess ist, der neben theologischen Fragestellungen auch soziologische, anthropologische und religionspsychologische Aspekte enthält, wird ein multidimensionaler Ansatz zur Erforschung von Bekehrungsmotiven konzipiert und ein Forschungswerkzeug erstellt, dass den Kontext südsudanesischer Migranten aufnimmt. Dieses kommt im Rahmen einer Pilotstudie zum Einsatz, die aus fünf Konvertiten-Interviews besteht. Zuerst wird der Inhalt jedes Interviews aus theologischer, soziologischer, religionspsychologischer und anthropologischer Sicht separat erhoben. Danach werden die unterschiedlichen Betrachtungsweisen in einen kritischen Dialog gebracht, um die Bekehrungsmotive zu bestimmen, welche den Kategorien kognitiv-religiös, mystisch-religiös, affektiv, experimentell oder sozial-politisch zugeordnet werden. Zum Schluss wird der Ertrag aller Interviews zu einem Gesamtergebnis verbunden und einer selbstkritischen Evaluierung unterzogen. Summary This dissertation examines conversion motives of Southern Sudanese migrants who live in an Islamic context. First of all a theological view of conversion in scripture and its development in the church history is presented. Since every conversion is a multi-dimensional process containing not only theological problems but also sociological, anthropological and religio¬psychlogical aspects, a multi-dimensional approach and a reseach methodology are designed for above context. This methodology is used for a pilot study of five interviews with converts. Each interview is examined separately from a theological, sociological, religio-psychological and anthropological analysis. After this the different views are brought into a critical dialog in order to identify the motives of conversion which are related to cognitive-religious, mystical¬religious, affective, experimental or social-political categories. The results of all individual interviews are merged in a final analysis and reflected in a self-critical evaluation. / Christian Spirituality, Church History and Missiology / M. Th. (Missiology)

One of the great challenges facing human systems today is how to prepare for, manage, and adapt successfully to the profound and rapid changes wreaked by disasters. Wellington, New Zealand, is a capital city at significant risk of devastating earthquake and tsunami, potentially requiring mass evacuations with little or short notice. Subsequent hardship and suffering due to widespread property damage and infrastructure failure could cause large areas of the Wellington Region to become uninhabitable for weeks to months. Previous research has shown that positive health and well-being are associated with disaster-resilient outcomes. Preventing adverse outcomes before disaster strikes, through developing strengths-based skill sets in health-protective attitudes and behaviours, is increasingly advocated in disaster research, practise, and management. This study hypothesised that well-being constructs involving an affective heuristic play vital roles in pathways to resilience as proximal determinants of health-protective behaviours. Specifically, this study examined the importance of health-related quality of life and subjective well-being in motivating evacuation preparedness, measured in a community sample (n=695) drawn from the general adult population of Wellington’s isolated eastern suburbs. Using a quantitative epidemiological approach, the study measured the prevalence of key quality of life indicators (physical and mental health, emotional well-being or “Sense of Coherence”, spiritual well-being, social well-being, and life satisfaction) using validated psychometric scales; analysed the strengths of association between these indicators and the level of evacuation preparedness at categorical and continuous levels of measurement; and tested the predictive power of the model to explain the variance in evacuation preparedness activity. This is the first study known to examine multi-dimensional positive health and global well-being as resilient processes for engaging in evacuation preparedness behaviour. A cross-sectional study design and quantitative survey were used to collect self-report data on the study variables; a postal questionnaire was fielded between November 2008 and March 2009 to a sampling frame developed through multi-stage cluster randomisation. The survey response rate was 28.5%, yielding a margin of error of +/- 3.8% with 95% confidence and 80% statistical power to detect a true correlation coefficient of 0.11 or greater. In addition to the primary study variables, data were collected on demographic and ancillary variables relating to contextual factors in the physical environment (risk perception of physical and personal vulnerability to disaster) and the social environment (through the construct of self-determination), and other measures of disaster preparedness. These data are reserved for future analyses. Results of correlational and regression analyses for the primary study variables show that Wellingtonians are highly individualistic in how their well-being influences their preparedness, and a majority are taking inadequate action to build their resilience to future disaster from earthquake- or tsunami-triggered evacuation. At a population level, the conceptual multi-dimensional model of health-related quality of life and global well-being tested in this study shows a positive association with evacuation preparedness at statistically significant levels. However, it must be emphasised that the strength of this relationship is weak, accounting for only 5-7% of the variability in evacuation preparedness. No single dimension of health-related quality of life or well-being stands out as a strong predictor of preparedness. The strongest associations for preparedness are in a positive direction for spiritual well-being, emotional well-being, and life satisfaction; all involve a sense of existential meaningfulness. Spiritual well-being is the only quality of life variable making a statistically significant unique contribution to explaining the variance observed in the regression models. Physical health status is weakly associated with preparedness in a negative direction at a continuous level of measurement. No association was found at statistically significant levels for mental health status and social well-being. These findings indicate that engaging in evacuation preparedness is a very complex, holistic, yet individualised decision-making process, and likely involves highly subjective considerations for what is personally relevant. Gender is not a factor. Those 18-24 years of age are least likely to prepare and evacuation preparedness increases with age. Multidimensional health and global well-being are important constructs to consider in disaster resilience for both pre-event and post-event timeframes. This work indicates a need for promoting self-management of risk and building resilience by incorporating a sense of personal meaning and importance into preparedness actions, and for future research into further understanding preparedness motivations.
