The class of hyperbolic conservation laws model the phenomena of non-linear wave propagation, including the presence and propagation of discontinuities and expansion waves. Such nonlinear systems can generate discontinuities in the so-lution even for smooth initial conditions. Presence of discontinuities results in break down of a solution in the classical sense and to show existence, weak for-mulation of a problem is required. Moreover, closed form solutions are di cult to obtain and in some cases such solutions are even unavailable. Thus, numerical algorithms play an important role in solving such systems. There are several dis-cretization techniques to solve hyperbolic systems numerically and Finite Volume Method (FVM) is one of such important frameworks. Numerical algorithms based on FVM are broadly classi ed into two categories, central discretization methods and upwind discretization methods. Various upwind and central discretization methods developed so far di er widely in terms of robustness, accuracy and ef-ciency and an ideal scheme with all these characteristics is yet to emerge. In this thesis, novel upwind and central schemes are formulated for various hyper-bolic systems, with the aim of maintaining right balance between accuracy and robustness. This thesis is divided into two parts. First part consists of the formulation of upwind methods to simulate genuine weakly hyperbolic (GWH) systems. Such systems do not possess full set of linearly independent (LI) eigenvectors and some of the examples include pressureless gas dynamics system, modi ed Burgers' sys-tem and further modi ed Burgers' system. The main challenge while formulating an upwind solver for GWH systems, using the concept of Flux Di erence Splitting (FDS), is to recover full set of LI eigenvectors, which is done through addition of generalized eigenvectors using the theory of Jordan Canonical Forms. Once the defective set of LI eigenvectors are completed, a novel (FDS-J) solver is for-mulated in such a manner that it is independent of generalized eigenvectors, as they are not unique. FDS-J solver is capable of capturing various shocks such as -shocks, 0-shocks and 00-shocks accurately. In this thesis, the FDS-J schemes are proposed for those GWH systems each of which have one particular repeated eigenvalue with arithmetic multiplicity (AM) greater than one. Moreover, each ux Jacobian matrix corresponding to such systems is similar to a unique Jordan matrix. After the successful treatment of genuine weakly hyperbolic systems, this strategy is further applied to those weakly hyperbolic subsystems which result on employ-ing various convection-pressure splittings to the Euler ux function. For example, Toro-Vazquez (TV) splitting and Zha-Bilgen (ZB) type splitting approaches to split the Euler ux function yield genuine weakly hyperbolic convective parts and strict hyperbolic pressure parts. Moreover, the ux Jacobian of each convective part is similar to a Jordan matrix with at least two lower order Jordan blocks. Based on the lines of FDS-J scheme, we develop two numerical schemes for Eu-ler equations using TV splitting and ZB type splitting. Both the new ZBS-FDS and TVS-FDS schemes are tested on various 1-D shock tube problems and out of two, contact capturing ZBS-FDS scheme is extended to 2-dimensional Euler system where it is tested successfully on various test cases including many shock instability problems. Second part of the thesis is associated with the development of simple, robust and accurate central solvers for systems of hyperbolic conservation laws. The idea of splitting schemes together with the notion of FDS is not easily extendable to systems such as shallow water equations. Thus, a novel central solver Convection Isolated Discontinuity Recognizing Algorithm (CIDRA) is formulated for shallow water equations. As the name suggests, the convective ux is isolated from the total ux in such a way that other ux, in present case other ux represents celerity part, must possess non-zero eigenvalue contribution. FVM framework is applied to each part separately and ux equivalence principle is used to x the coe cient of numerical di usion. CIDRA for SWE is computed on various 1-D and 2-D benchmark problems and extended to Euler systems e ortlessly. As a further improvement, a scalar di usion based algorithm CIDRA-1 is designed for v Euler systems. The scalar di usion coe cient depends on that particular part of the Rankine-Hugoniot (R-H) condition which involves total energy of the system as a direct contribution. This algorithm is applied to a variety of shock tube test cases including a class of low density ow problems and also to various 2-D test problems successfully. vi

Since the advent of the millennium, a growing interest has arisen in information and communication technologies (ICT) given the potential to bridge the digital divide. ICT have had a central role to play in terms of economic, regulatory and political development. Telecommunications is used in this thesis as a sector case to study policy diffusion, which focuses on the movement of policies across borders and actors. This thesis answers the following research question: does policy diffusion take place in the telecommunications sector in the Middle East and North African (MENA) countries? This is answered using qualitative methods, such as expert interviews and the comparison of six cases, composed of two sectors of ICT; Universal Service Obligation (USO) and spectrum management, and of three countries; Morocco, Jordan and Egypt. In case the research question is positively answered two further foci are central to the thesis. Firstly, the thesis explores the conditions leading to policy diffusion. The thesis argues that the conditions leading to policy diffusion are linked to different degrees of vulnerability of countries to external actors. This vulnerability is described through four variables, which reveals the levels of governance and market openness and economic and political interconnectedness of the adopting countries. Secondly, it scrutinizes the links between sector variables and mechanisms of diffusion. The argument of this part is that different combinations of these sector variables support the differentiation across the four traditional mechanisms of policy diffusion; learning, imitation, competition and coercion. The main contributions of this thesis are both theoretical, to the literature of policy diffusion and empirical, regarding telecommunications regulation in three MENA countries. The thesis underlines the key role of government administrations as the main driver for policy change in MENA countries, compared to international pressures and market forces. Furthermore this thesis concludes that, in the telecommunications sector, transgovernmental channels are nowadays omnipresent in the phenomenon of policy diffusion and are thus not sufficient to disentangle mechanisms of diffusion. The thesis examines the additional factors of efficiency, economic interests and sanction capacity for explanatory power.

Dans ce travail de recherche qui s’inscrit dans le cadre d’une thèse en sciences du langage, notre intérêt s’est porté sur les problèmes que rencontrent les jordaniens qui apprennent la langue française lors de la réalisation des productions écrites. Nous avons trouvé que l’interférence constitue une difficulté majeure à laquelle se heurtent fréquemment les apprenants ; elle constitue par conséquent un défi pour l’enseignement du français. Dans cette recherche sur l’analyse des erreurs orthographiques grammaticales et lexicales, qui se base sur une enquête effectuée au département de langue et littérature française à l’université de Jordanie à Amman, nous avons tenté de repérer les erreurs commises, de comprendre leurs causes, de connaître de quelle manière la langue maternelle des apprenants (l'arabe jordanien) et la première langue étrangère dans le pays (l'anglais) marquent leurs productions écrites. Nous avons ensuite cherché à y remédier dans une perspective visant le développement des compétences orthographiques des apprenants et également de l’enseignement du français en Jordanie en fonction de leurs besoins et attentes, afin d’introduire une méthodologie efficace pour l’apprentissage du français langue étrangère. / In this research which is part of a thesis in linguistics, our interest was focused on the problems faced by Jordanian students who learn the French language when producing written work. We found that interference is a major difficulty that learners affronted frequently; it is therefore a challenge for the teaching of French. In this research the analysis of grammatical and lexical spelling errors, based on a survey in French language and literature department at the University of Jordan in Amman, we have attempted to identify the mistakes, understand their causes to know how the learners' mother tongue (Jordanian Arabic) and the first foreign language in the country (English) mark their written productions. We then sought to remedy with a view to the development of spelling skills of learners and also the teaching of French in Jordan according to their needs and expectations in order to introduce an effective methodology for learning French language.

Smoking prevalence among adolescents in the Middle East remains high while rates of smoking have been declining among adolescents elsewhere. The aims of this research were to (1) describe patterns of cigarette and waterpipe (WP) smoking, (2) identify determinants of WP smoking initiation, and (3) identify determinants of cigarette smoking initiation in a cohort of Jordanian school children. Among this cohort of school children in Irbid, Jordan, (age ≈ 12.6 at baseline) the first aim (N=1,781) described time trends in smoking behavior, age at initiation, and changes in frequency of smoking from 2008-2011 (grades 7 – 10). The second aim (N=1,243) identified determinants of WP initiation among WP-naïve students; and the third aim (N=1,454) identified determinants of cigarette smoking initiation among cigarette naïve participants. Determinants of initiation were assessed with generalized mixed models. All analyses were stratified by gender. Baseline prevalence of current smoking (cigarettes or WP) for boys and girls was 22.9% and 8.7% respectively. Prevalence of ever- and current- any smoking, cigarette smoking, WP smoking, and dual cigarette/WP smoking was higher in boys than girls each year (p These studies reveal intensive smoking patterns at early ages among Jordanian youth in Irbid, characterized by a predominance of WP smoking. WP may be a vehicle for tobacco dependence and subsequent cigarette uptake. The sizeable incidence of WP and cigarette initiation among students of both sexes points to a need for culturally relevant smoking prevention interventions. Gender-specific factors, refusal skills, and smoking cessation of both WP and cigarettes for youth and their parents/teachers would be important components of such initiatives.

The aim of this dissertation is to give explicit descriptions of the set of proper holomorphic mappings between two complex manifolds with reasonable restrictions on the domain and target spaces. Without any restrictions, this problem is intractable even when posed for do-mains in . We give partial results for special classes of manifolds. We study, broadly, two types of structure results: Descriptive. The first result of this thesis is a structure theorem for finite proper holomorphic mappings between products of connected, hyperbolic open subsets of compact Riemann surfaces. A special case of our result follows from the techniques used in a classical result due to Remmert and Stein, adapted to the above setting. However, the presence of factors that have no boundary or boundaries that consist of a discrete set of points necessitates the use of techniques that are quite divergent from those used by Remmert and Stein. We make use of a finiteness theorem of Imayoshi to deal with these factors. Rigidity. A famous theorem of H. Alexander proves the non-existence of non-injective proper holomorphic self-maps of the unit ball in . ,n >1. Several extensions of this result for various classes of domains have been established since the appearance of Alexander’s result, and it is conjectured that the result is true for all bounded domains in . , n > 1, whose boundary is C2-smooth. This conjecture is still very far from being settled. Our first rigidity result establishes the non-existence of non-injective proper holomorphic self-maps of bounded, balanced pseudo convex domains of finite type (in the sense of D’Angelo) in ,n >1. This generalizes a result in 2, by Coupet, Pan and Sukhov, to higher dimensions. As in Coupet–Pan–Sukhov, the aforementioned domains need not have real-analytic boundaries. However, in higher dimensions, several aspects of their argument do not work. Instead, we exploit the circular symmetry and a recent result in complex dynamics by Opshtein. Our next rigidity result is for bounded symmetric domains. We prove that a proper holomorphic map between two non-planar bounded symmetric domains of the same dimension, one of them being irreducible, is a biholomorphism. Our methods allow us to give a single, all-encompassing argument that unifies the various special cases in which this result is known. Furthermore, our proof of this result does not rely on the fine structure (in the sense of Wolf et al.) of bounded symmetric domains. Thus, we are able to apply our techniques to more general classes of domains. We illustrate this by proving a rigidity result for certain convex balanced domains whose automorphism groups are assumed to only be non-compact. For bounded symmetric domains, our key tool is that of Jordan triple systems, which is used to describe the boundary geometry.

This graduation thesis describes life in the border village Podmokly in the period between 1853-1918. The author presents the penetration of the Saxon capital at this time and further developing the business mostly Germans from Saxony in the chocolate industry. It focuses on chocolate, which at that time originated in the village, and the chocolate Jordan & Timaeus, Hartwig & Vogel, and Otto Rüger. Initially focused on the development of village Podmokly, the characteristic time, the amount of customs duties and surcharges on raw materials for production of chocolate and cocoa. In this work the author shows contemporary practice in the manufacture of chocolate, recipes and curiosities, which were associated with the production of chocolate. The analysis of chocolate, the author focuses on the history of chocolate on the description of the factory and its reorganization, social policy, in compliance with regulations and laws that were created at this time. Furthermore, the author explores the field of advertising, international exhibitions, sales and production of chocolate and firm structure. The work is drawn primarily from contemporary sources, or. journal of modern literature and scientific studies

En 1849, Arthur Cayley et George Salmon démontrent que toute surface cubique contient exactement vingt-sept droites. Résultat célèbre de la deuxième moitié du 19ème siècle, ce théorème a notamment donné lieu à des recherches sur une équation algébrique particulière appelée "équation aux vingt-sept droites". Dans notre thèse, nous étudions les rapprochements entre groupes, équations et géométrie opérés dans ces recherches. Après un travail préparatoire mettant en place certains points mathématiques et chronologiques associés aux vingt-sept droites, nous nous intéressons au Traité des substitutions et des équations algébriques de Camille Jordan, publié en 1870. Cet ouvrage contient une section consacrée à l'équation aux vingt-sept droites dont nous analysons en détail les mathématiques. Pour mettre en contexte certains points, un corpus plus large est ensuite construit autour des "équations de la géométrie", famille d'équations associées à des configurations géométriques dont les vingt-sept droites ne sont qu'un exemple. Ce corpus s'étend de 1847 à 1896, et ses principaux auteurs sont Jordan, Alfred Clebsch et Felix Klein. Dans le but de rendre compte de l'organisation particulière du savoir partagé dans le corpus, nous discutons et utilisons alors la notion de "culture". Enfin, nous étudions précisément deux textes du corpus proposant de géométriser certaines parties de l'algèbre et nous montrons en quoi les équations de la géométrie ont participé à une compréhension géométrique de la théorie des substitutions ainsi qu'à l'élaboration des idées du Programme d'Erlangen de Klein (1872). / In 1849, Arthur Cayley and George Salmon proved that every cubic surface contains exactly twenty-seven lines. A famous result in the second half of the 19th century, this theorem gave rise to research about a particular algebraic equation called the "twenty-seven lines equation." In our thesis, we study how groups, equations, and geometry interact throughout this research. After a preparatory work presenting some mathematical and chronological points about the twenty-seven lines, we look into Camille Jordan's Traité des substitutions et des équations algébriques, published in 1870. This book contained a section devoted to the twenty-seven lines equation, the mathematics of which we thoroughly study. In order to contextualize some elements, a larger corpus is then built around "geometrical equations," a family of equations linked to geometrical configurations among which the twenty-seven lines are just one example. The corpus extends from 1847 to 1896 and its main authors are Jordan, Alfred Clebsch, and Felix Klein. Aiming at describing the particular organization of the knowledge shared in the corpus, we then discuss and use the notion of "culture." Finally, we closely study two texts of the corpus, each of them presenting a geometrization of a part of algebra, and we ascertain that geometrical equations participated to a geometrical understanding of substitution theory as well as the elaboration of the ideas of Klein's Erlanger Programm (1872).

The main purpose of this research is to investigate Jordan and Israel's participation in the Red Sea – Dead Sea Water Convenience project from human security point of view. The Red Sea – Dead Sea Water Conveyance project is planned to desalinate water from Red Sea to the Dead Sea and provide fresh water to Jordan, Israel and possibly Palestine. I use a human security approach in this investigation because it has a broader people-centered security perspective. This approach guides the research to consider water related issues and challenges in Jordan and Israel to which the project can be a possible solution. I use qualitative content analysis to investigate the issues identified by Jordan and Israel, and how the project is estimated to address these challenges. I argue that the estimated benefits that the implementation of the project provides for human well-being in Jordan and Israel makes them to participate in this project.

This thesis is an analysis of the Jordanian economic developmental process which demonstrates that it expanded rapidly between 1948 and 1970. During the period under study, Jordan had to face two wars, in 1948 and 1967, which had inverse effects on the economy. After each war, the economy experienced a period of recovery due primarily to government efforts to promote investment; the existence of a more educated people represented by the refugees; and the role of foreign aid. Chapter I is a brief introduction to the Jordanian economy. Chapter II is a discussion of some theories of economic development. Chapters III and IV provide us with a more detailed description of the economic situation before and after the 1967 war. However, the purpose of Chapter V is to incorporate the theory that appears to handle the processes discussed in both Chapters III and IV.

We describe canonical forms for elements of a classical Lie group of matrices under similarity transformations in the group. Matrices in the associated Lie algebra and Jordan algebra of matrices inherit related forms under these similarity transformations. In general, one cannot achieve diagonal or Schur form, but the form that can be achieved displays the eigenvalues of the matrix. We also discuss matrices in intersections of these classes and their Schur-like forms. Such multistructered matrices arise in applications from quantum physics and quantum chemistry.
