Dissociation des Extensions Algébriques de Corps par les Extensions Galoisiennes ou Galsimples non GaloisiennesAndréo, Emmanuel 15 June 2004 (has links) (PDF)
Le théorème fondamental de l'Arithmétique factorise tout nombre entier en produit de nombres premiers. Le théorème de Jordan-Hölder dévisse de nombreux groupes par leurs suites normales qui se raffinent en suites de composition. Le thème central de cette étude est celui de la dissociation des extensions de corps. Nous dissocions les extensions algébriques par leurs corps intermédiaires de façon à constituer une tour qui comporte le plus grand nombre possible de marches galoisiennes. Nous appelons "galtourables" les extensions admettant une tour de corps dont toutes les marches sont galoisiennes (dite "tour galoisienne"). Deux tours galoisiennes d'une même extension galtourable (finie ou infinie) admettent des raffinements équivalents. Mais il existe des extensions algébriques non galtourables. A toute extension finie est attaché un corps intermédiaire unique, son "corps d'intourabilité", au-delà duquel l'extension n'est plus galtourable. L'ultime marche d'une "tour d'élévation" d'une extension non galourable est alors dite "galsimple" et elle est non galoisienne. Le théorème final de cette thèse dissocie toute extension finie par ses tours d'élévation qui se raffinent en "tours de composition". Nous obtenons ainsi un analogue pour les extensions de corps du théorème de Jordan-Hölder pour les groupes.

Pictures and Popery : religious art in England c. 1680-c. 1760Haynes, Clare January 2001 (has links)
During the first half of the `long' eighteenth century the English were, as a nation, vehemently anti-Catholic, yet the art that was most admired, collected and talked about, was Catholic in origin and subject matter (pictures showing the intercession of saints or the figure of God, for example). Such art might have been rejected by English collectors, certainly idolatry was chief among the heresies ascribed to the Papists, but the belief in the supremacy of Italian art was long-standing and tenacious in pan-European culture. The thesis demonstrates that rather than rejecting it, elaborate strategies were developed which allowed the cultural and social value of ownership and knowledge of this canonical art to accrue, whilst managing its potentially troubling content. For example, the royal ownership of the Raphael Cartoons (c. 1514) was a matter of increasing national pride during this period, which is surprising at first sight, given their provenance and their celebration of the apostolic succession of the Papacy from SS Peter and Paul. These meanings were not expunged from the Cartoons by English commentators, instead means were found to transpose them into a Protestant register and to maintain Raphael's reputation as the great universal artist. Each chapter of the thesis offers a different mode of address to the central theme, exploring, for example, the encounters grand tourists had with canonical art in Catholic churches in Rome and the ways in which the Catholic meanings of pictures were managed in a collection. In another chapter I explore how art was used and discussed within the Church of England. It has become clear that the Catholic associations of art did present a historically-significant political challenge to English connoisseurs and that, for example, new histories and theories of art, modified from their continental models, were developed to facilitate its acceptance. In addition, by paying careful attention to the ways in which issues of class, nationhood and culture were managed in relation to this problem, insights into the complex nature of anti-Catholicism in England have been gained.

Iranian Female Tour Guides’ Perceptions of Working in the Tourism IndustryMahdavi Zafarghandi, Mahdi January 2016 (has links)
It is expected that tourism industry is one of the fields that can boost female employment and therefore, can help redress the balance and empower women in Iran. Equal opportunities in employment assist them for empowerment. Being a tour guide is one of these opportunities, although most jobs are created elsewhere, e.g. hotels and restaurants. But for this thesis, tour guides are important from two aspects: first, it is a challenging condition that you find out what you are capable of and second; it is not an extension of traditional domestic roles, and it is a new role for women in a male-dominated job market.This study aims to investigate how female tour guides perceive their roles in the tourism industry and the elements of these perceptions among their family, colleagues, and tourists who could serve empowering or disempowering.

Právní úprava zájezdu / Legal regulation of package tourŠedivý, David January 2017 (has links)
The main object of this thesis is to summarize legal regulation about package tour in czech legal order, define and describe subject of this contractual relationship, define contracting parties and individual rights and duties that are being established at the beginning or during this contractual relationship. Basic concepts linked to the package tour contract as well as the role of travel agency in the whole process are being analysed in this thesis. I also focused on the most important changes connected with passing of the New Civil Code when individual provisions are examined and their significance is explained. Similarly as a legal ground of this contractual type the directive 90/314 EEC is also being examined. Finally, this thesis evaluates whether implementation of this directive to czech legal order has been done correctly and whether czech laws comply with the basic rules this directive is based on. The thesis is composed of nine chapters, each of them dedicated to individual issue. In the introduction I define basic objective of this thesis. The following chapter focuses on the basic definiton, purpose, basic concepts and character of this contractual relationship. In the third most comprehensive chapter I analyse concrete requirements of package tour contract, individual rights and duties...

Marketingové oživení Cool tour linky / Marketing Revival of 'Cool tour linka'Majerová, Jolana January 2010 (has links)
The theme of this master's thesis is "Marketing Revival of 'Cool tour linka'". 'Cool tour linka' is a joint project of Prague's leading exhibition institutions and transport company. Introductory part presents the project with the aim to preserve it "for next generations" too. 'Cool tour linka' was terminated due to economical reasons. Therefore the thesis leads to formation of a new project, that would work under even less favourable conditions. Conclusions from the chapters that analyse the previous 'Cool tour linka' (analysis of the visitors' attendance, application of marketing tools, SWOT analysis) are used in the new project. Both the original and the newly proposed 'Cool tour linka' emphasize the element of cooperation of the organisations operating in the field of culture and the importance of unusual presentation of arts collections to the public.

Tour Guides and Sustainable Development: the Case of Hainan, ChinaHu, Wei 15 February 2007 (has links)
Tour guides are one of the most visible players in tourism but little scholarly attention has been given to the links that tour guides may have with sustainable development. This study addresses the gap by promoting an understanding of how tour guides can assist in moving tourism in a sustainable direction. Sustainable development is expected to improve the quality of life for all people without causing undesirable ecological and socio-cultural outcomes. As a central agent in the entire tourism system, tour guides have a variety of roles to play in response to the expectations of the various tourism stakeholders. A literature review suggests that tour guides can contribute to destinations'sustainable development by exerting their functions on experience management, resources management and local economic promotion. Interpretative guiding is the means by which tour guides can realize these above potentials. A case study was conducted in Hainan, China. The guiding performance there was examined to see whether and to what extent tour guides are contributing to the achievement of local sustainability. It was discovered that the tour guides in Hainan do not exert (well) their expected functions either in enhancing enjoyable experiences for tourists, in supporting local resource conservation, or in promoting the healthy development of the local economy. Their potentials are blocked by the issues and problems of instant money-making-centered guiding conduct, below-cost group receiving industry practices and unfair remuneration system for the guides, absence of protection measures to ensure the guides’ interests, opportunism in guiding and lenient certificating requirements, lack of professionalism and effective training, ineffective monitoring measures, and limited awareness of sustainable development. In order to better the situation, unhealthy travel and trade industry practice should be banned; effective certificating, training and monitoring measures should be developed and implemented; tour guides’ personal interests should be protected and local awareness of sustainability, in particular that of the industry members, should be fostered. Serious efforts of the government administration as well as industry members and tour guides are required if tour guides are to fulfill their potential as agents of sustainable development.

The STAPL pListXu, Xiabing 2010 December 1900 (has links)
We present the design and implementation of the Standard Template Adap-
tive Parallel Library (stapl) pList, a parallel container that has the properties of
a sequential list, but allows for scalable concurrent access when used in a paral-
lel program. The stapl is a parallel programming library that extends C with
support for parallelism. stapl provides a collection of distributed data structures
(pContainers) and parallel algorithms (pAlgorithms) and a generic methodology
for extending them to provide customized functionality. stapl pContainers are
thread-safe, concurrent objects, providing appropriate interfaces (pViews) that can
be used by generic pAlgorithms.
The pList provides Standard Template Library (stl) equivalent methods, such
as insert, erase, and splice, additional methods such as split, and efficient asyn-
chronous (non-blocking) variants of some methods for improved parallel performance.
List related algorithms such as list ranking, Euler Tour (ET), and its applications to
compute tree based functions can be computed efficiently and expressed naturally
using the pList.
Lists are not usually considered useful in parallel algorithms because they do
not allow random access to its elements. Instead, they access elements through a
serializing traversal of the list. Our design of the pList, which consists of a collec-
tion of distributed lists (base containers), provides almost random access to its base
containers. The degree of parallelism supported can be tuned by setting the number of base containers. Thus, a key feature of the pList is that it offers the advantages
of a classical list while enabling scalable parallelism.
We evaluate the performance of the stapl pList on an IBM Power 5 cluster and
on a CRAY XT4 massively parallel processing system. Although lists are generally not
considered good data structures for parallel processing, we show that pList methods
and pAlgorithms, and list related algorithms such as list ranking and ET technique
operating on pLists provide good scalability on more than 16, 000 processors. We
also show that the pList compares favorably with other dynamic data structures
such as the pVector that explicitly support random access.
