L'objectif de cette thèse est de modéliser les changements en chaîne historiques dans les théories phonologiques modernes. Martinet (1952, 1955, 1970) distingue deux principales catégories de changements en chaîne: les chaînes de propulsion et les chaînes de traction. Les chaînes de propulsion seront traitées dans la première partie de cette thèse (chapitres 2 et 3). Afin de modéliser les chaînes de propulsion, un modèle existant est utilisé: La théorie de préservation du contraste de Łubowicz (2003, 2012). Concernant la modélisation des chaînes de traction, qui sera principalement traitée dans la seconde partie de le thèse (chapitres 4 et 5), une nouvelle théorie sera proposée, basée sur les travaux phonétiques de De Boer (2001). Cette proposition est basée sur la notion des domaines piliers. Le chapitre 1 s'ouvre sur l'observation que ni les théories dérivationnelles orientées vers l'input – type SPE – ni les théories orientées vers l'output, comme la théorie de l'optimalité de Prince & Smolensky (TO) sont en mesure de formaliser les changements en chaîne. Dans les théories dérivationnelles, il est possible d'obtenir une bonne description des changements en chaîne. Cependant, afin de faire cela, nous devons briser les liens unissant les différentes étapes des changements en chaîne. Par conséquent, nous perdons l'interdépendance systémique entre les stades, ce qui est au cœur des changements en chaîne. Concernant la théorie de l'optimalité, sa structure stricte sur deux niveaux se révèle problématique dans le cas des changements en chaîne. Dans un changement en chaîne schématique comme /a/ → [e] > /e/ → [i], il est impossible pour la TO, dans la même analyse, de faire en sorte que [e] soit un candidat optimal et /e/ un candidat bloqué. Dans le chapitre 2, nous analysons et comparons plusieurs amendements à la théorie de l'optimalité proposés pour rendre compte des changements en chaîne. Beaucoup d'entre eux ne sont pas satisfaisants dans le cas des changements en chaîne car ils ne parviennent pas à modéliser la force systémique des changements en chaîne. La seule théorie qui semble accomplir cet objectif est la théorie de préservation du contraste (CPT) de Łubowicz. Cette théorie est basée sur les notions de contraste, préservation du contraste et elle évalue des scénarios au lieu de candidats individuels. La préservation du contraste est accomplie à travers la transformation du contraste. La notion de transformation du contraste signifie que les niveaux de contraste du système pré-changement sont préservés dans le système post-changement mais leur nature change. Une observation sur la CPT est que Łubowicz l'avait originellement conçue pour les changements en chaîne synchroniques. Dans le chapitre 2, nous démontrons que la CPT est en mesure de modéliser la force systémique qui donne aux changements en chaîne diachroniques leur cohérence. Ainsi, dans le chapitre 3, nous décidons de tester la validité de la CPT sur de véritables changements en chaîne historiques. Nous avançons deux études de cas sur deux changements en chaîne. Le premier, bien connu, est le changement en chaîne vocalique du Grand Changement Vocalique Anglais (English Great Vowel Shift). L'autre changement en chaîne est la Seconde Mutation Consonantique allemande (High German Consonant Shift). Nous démontrons que la CPT est en mesure de rendre compte de ces deux changements en chaîne. Au terme du chapitre 3, la CPT est testée sur une autre catégorie de changements en chaîne : les changements en chaîne observés dans l'acquisition de la langue maternelle. Le changement en chaîne étudié est s → θ → f. Ce changement en chaîne est différent des deux autres car il n'y a pas de nouveau niveau de contraste créé. Le dernier stade du changement en chaîne se conclut par une fusion. Encore une fois, la CPT peut rendre compte de ce changement en chaîne de manière satisfaisante. / The aim of this thesis is to formalise historical chain shifts within modern phonological theories. Martinet (1952, 1955, 1970) distinguishes two main categories of chain shifts: push chains and pull chains. Push chains will be dealt with in the first main part of this thesis (chapters 2 and 3). For modelling of push chains, an existing model is used: Łubowicz's (2003, 2012) Contrast Preservation Theory. For modelling pull chains, which will be the focus of the second part of this thesis (chapters 4 and 5), a new theory will be proposed, based on the phonetic work by De Boer (2001). This proposition is based on the notion of the pillar domains (domaines piliers). Chapter 1 starts with the observation that neither the derivational, SPE-like, theories or output driven theories like Prince's & Smolensky's Optimality Theory (OT) are able to formalise chain shifts properly. Within the derivational theories, it is possible to get a correct description of a chain shift. However, in order to do that, we have to break the links between the different stages of the chain shift. Therefore, one loses the systemic interdependence of the different stages, which is the essence of the chain shift. As regards to Optimality Theory, it is the two-level structure of the theory which proves problematic for chain shifts. In a theoretical chain shift such as /a/ → [e] > /e/ → [i], it is impossible for OT to make, in the same analysis, [e] an optimal candidate and /e/ a non-optimal one. In chapter 2, we analyse and compare several output-driven propositions that have been made to account for chain shifts. Many of them are not satisfactory because they do not manage to model the systemic motivation of chain shifts. The only theory that seems able to complete this objective is Łubowicz's Contrast Preservation Theory (CPT). This theory is based on the notions of contrast, contrast preservation and it evaluates scenarios rather than individual candidates. Contrast preservation is achieved through contrast transformation. The term contrast transformation indicates that the contrast levels of the input system are preserved but that their nature is different in the output system. One observation about CPT is that Łubowicz designed it for synchronic chain shifts. In chapter 2, we prove that CPT is able to model the perceptible coherence in diachronic chain shifts. In chapter 3, thus we decide to test the validity of CPT on actual historical chain shifts. It is tested on two cases. One is the well-known vocalic chain shift the Great Vowel Shift in English. The other one is the Second German Sound Shift (or High German Consonant Shift). We demonstrate that CPT is able to account for both of these chain shifts. At the end of chapter 3, CPT is tested on another type of chain shifts, i.e. chain shifts in first-language acquisition. The studied chain shift is s → θ → f. This chain shift is different from the other two because there is no new contrast level created. The last stage of this chain shift ends with a merger . Once again, CPT can account for this chain shift in a coherent way.

Comment les Tahitiens ont-ils conceptualisé le ciel pour en faire un instrument de mesure astronomique ? Leurs traditions apportent des explications sous forme de récits cosmogoniques. Ils peuvent nous envoûter mais, ils ne sont pas considérés comme des solutions scientifiques. L'astronomie a accordé aux théories qui ont cours aujourd'hui toutes les apparences du sérieux et de la rationalité. La cosmogonie a commencé le jour où l'homme s'est posé des questions sur son environnement et ses origines. Il fallait demander à ceux qui avaient voyagé, de raconter ce qu’ils avaient vu et entendu sur les régions encore plus lointaines. Les Tahitiens font partie de ces curieux qui sont allés voir ce qu’il y avait au-delà de l’horizon et pour qui la parole d’un ancêtre était acte de foi. Les réponses se trouvent donc dans les récits mythiques et le vocabulaire utilisé, à la source des symboles intellectuels. Pour les déchiffrer, l’approche linguistique est indispensable.Dans la cosmogonie tahitienne, le dieu Ta’aroa crée le monde. Le ciel demeure cependant uni à la terre, il le soulève à l’aide de dix piliers (pou), que repèrent des étoiles appelées ‘anā. Les objets célestes peuvent ainsi émerger des abysses à l’horizon et se mouvoir sur le dôme en traçant une dizaine de chemins (rua), guidés par les plus remarquables d’entre eux, les ta’urua. Cette conceptualisation du ciel offrira aux Tahitiens un instrument de mesure spatiotemporel remarquable.Leur lexique astronomique comporte près de deux cents termes porteurs de concepts. Les revisiter conduit à découvrir leur ancienne science. / How did the Tahitians conceptualize the skies in order to create their own instrument of astronomy? Traditions provide explanations in the form of cosmogony stories. They can entice or by no means are they considered scientific evidence. Astronomy has supported theories that give today a certain seriousness or rationality.Cosmogony began the day when man inquired about its environment and its origins. To fully understand, they asked those that have travelled in the past, recollecting descriptions of what they had seen and heard from faraway places.The curiosity of Tahitians has pushed them to travel beyond the horizon having only faith in the words of their ancestors. The answers can be found within the mythical recitals by understanding the vocabulary used at the source of intellectual symbols. Without a doubt, the approach of a linguist is necessary.In Tahitian cosmogony, the God Ta'aroa created the world. The sky was attached to the earth and in order to separate them; he used ten pillars "Pou", that are marked by stars in the sky called "'Anā". Celestial bodies move across the dome sky by following pathways called "Rua" and each pathway is highlighted by a dominant star called "Ta'urua". This conceptualization of the sky gave Tahitians a remarkable instrument for measuring space and time. The lexicon of astronomy terms numbers nearly two hundred. Understanding them leads one to discover their ancient science.

The thesis is focused on the evaluation of the application of corporate social responsibility concept in Czech Republic. The main aim is to make an analysis of the impact of activities from social pillar of CSR to enhance employee loyalty. The theoretical part provides an interpretation of the corporate social responsibility concept and also a description of the evaluation methodology KORP. During the solution social pillars of corporate social responsibility are evaluated by KORP and by using description method in three selected Czech companies. The results are compared by using comparative analysis with the results of a questionnaire survey among employees of selected companies. The conclusion of the thesis provides further opportunities for improvement in CSR application in order to strengthen employee loayalty to his company.

The diploma thesis deals with the construction of the technical project of the SO210 bridge over the stream Hluchová on the I / 11 road. The bridge is designed as reinforced concrete, additionally prestessed with a length of 70m. The thesis was processed within the scope of DP assignment.

The diploma thesis deals with superstructure of apartment building in brno, which is located in a row house construction. The goal of the diploma thesis is to design new supporting structures and minimize the load from these construction because of low reservs in the load capacity of the existing supporting walls. the thesis contains a technical report, analysis of statics, drawing documentation and visualization. The internal forces were executed by software scia engineer.

This thesis describes the current state of the river Oslava in Oslavany design and reconstruction of the existing fixed weir in the affected location. As a best alternative reconstruction of the existing fixed weir reconstruction was chosen the hard threshold floating weir inflatable weirs. The next part of the thesis describes the proposed solution, and the last part of the thesis deals with the assessment of the proposed solutions.

The master thesis is aimed for design and assessment of main bearing segments of reinforced concrete structure of apartment block: monolithic reinforced concrete slab over the second floor, foundation slab, stairway slab, pillar and wall beam. Constituent part of the thesis is also drawing documentation of reinforcement of selected segments. Calculation of the internal forces is made at graphical software system Scia Engineer.

Final thesis with tittle: "Monolithic multi-storey wall building" is processeed as a project documentation according to valid assesment. The object is located in the city of Boskovice, 35 Hybešova street. Its ground plan dimensions are 52,8m x 12,5m. Total height of object is 22,3m including roof-wall, measured from the level of base chink. There are enclosed balconies on the south direction. Movement between floors is ensured by 2-flighted stairs. Object is It is made of reinforced concrete. It is designed as 6-floor bulding with a flat roof. The main supporting construction is created by system of walls and reciprocally asigned ceilings, which are sticked together. Walls are designed as pillars. The building is assigned to a belt bases. Module dimensions are 8,7m in longitudinal direction and 5,2m in transversal direction. Height dimension is 3,0m. The thesis is dealing with the 1st upper floor.

The aim of this thesis is an analysis of the construction of a trailer used for transporting concrete pillars. The main part of the thesis is focused on frame construction. For the calculation of load states a multi body system was used, whereby a simulation of transport in terrain was performed. The results from these calculations will be used as limiting conditions for strength control. The method of solution is the finite element method. All acquired results will be analysed and according to them changes will be made to the frame construction. In addition to this, the thesis contains drawings documenting the above-mentioned changes.

The aim of the thesis is to find the answer, whether it is plausible to monitor social cohesion of the municipality and how to measure this cohesion, which is one of the essential pillars of sustainable development. In order to find out, analysis of approaches and measurements of the sustainable development social pillar in international and Czech environment was carried out. Social pillar was identified and described also at the local level. Within the framework of the sustainable development social pillar at the municipal level three main thematic blocks are proposed: • Social environment quality of the municipality • Social-demographic population structure of the municipality • Contentment and participation in the public affairs These themes should be monitored by the set of indicators proposed in this thesis. It aimed to cover all dimensions of social cohesion which are significant and well-founded in the context of the territorial planning process. These indicators can be followed in the direct relationship with the population size and regional importance of the observed territorial unit at the local level and they are not separated from the concept of indicators monitoring at other – territorially higher – levels. Outcomes, analysis and interpretation of attained values could become the basis for the “territorial sustainable development analysis” (part of territorial planning instruments according to contemporary legal regulations), representing social pillar. All phenomenon and processes must be evaluated in the context with other sustainable development pillars and afterwards they should become another suitable instrument for measurement of the fulfilling the territorial planning aims.
