Les pèlerines, la religion vécue et la Roumanie postcommuniste

À la fin de l’année 1989, la Roumanie entamait son chemin vers la démocratie. Depuis, le pays a connu de nombreux changements dont une « revitalisation religieuse ». L’attrait pour la religion en Roumanie a suscité l’intérêt des chercheurs qui ont tenté de rendre compte de comportements qu’ils jugeaient contraires aux thèses des théories de la sécularisation et de la modernisation. Ma thèse part d’une critique de ces études qui, concentrées sur ces théories, omettent trop souvent l’action des individus dans la vie de tous les jours. Dans la présente recherche, j’utilise l’approche de la religion vécue pour me pencher sur des individus et leur manière de comprendre, d’exprimer, de pratiquer et d’expérimenter la religion au jour le jour. D’une manière réflexive, ma thèse examine la religion vécue dans la Roumanie postcommuniste à partir de pèlerinages réalisés durant le printemps et l’automne 2012 dans des monastères réputés pour leurs miracles, leurs confesseurs charismatiques ou leurs reliques. En raison de leur présence nombreuse dans les pèlerinages, les femmes se sont imposées comme les artisanes de la religion vécue en Roumanie. Elles sont au centre de ma thèse. En observant leurs croyances et leurs pratiques — et sans omettre la religion vécue des « porteurs de la religion officielle » —, j’explore des thèmes qui constituent autant de facettes de la religion vécue : le sort, le charisme, la matérialité et les reliques. Ma thèse propose deux contributions à la recherche. 1) L’étude de la pratique de la religion des pèlerines nous renseigne sur la manière dont la religion est comprise et pratiquée dans un contexte orthodoxe. Elle laisse également entrevoir les conséquences de cette pratique dans la Roumanie postcommuniste : en effet, la religion vécue s’avère un véhicule de valeurs qui s’opposent au discours démocratique officiel. 2) L’étude propose une contribution théorique et méthodologique à l’approche de la religion vécue. Le matériau empirique sur lequel elle repose indique que la religion vécue prend racine dans l’Église pour ensuite circuler entre les femmes et les représentants de l’institution. Dans ce mouvement de va-et-vient, la religion vécue appartient aux pèlerines, mais aussi aux « porteurs de la religion officielle ».

Femmes autochtones et intersectionnalité : féminisme autochtone et le discours libéral des droits de la personne

Les femmes autochtones vivent une discrimination intersectionnelle, en ce qu’elle provient d’au moins deux sources: le genre et la race (ou la culture), et qu’elle est plus complexe que la somme de ses sources. Par conséquent, les revendications des femmes autochtones se situent sur au moins deux plans: elles ont des revendications comme autochtones au sein de la population canadienne et comme femmes à l’intérieur de leurs communautés. Partant de la prémisse que l’État canadien doit reconnaître le droit à l’autodétermination des peuples autochtones et par le fait même le droit autochtone, nous nous interrogeons sur les moyens qui permettraient aux femmes autochtones d’exercer l’influence nécessaire pour faire reconnaître et accepter leurs revendications politiques et juridiques dans les processus décisionnels de leurs communautés. Féminisme et revendications autochtones sont-ils nécessairement antinomiques? Pour certaines auteures autochtones, une approche libérale fondée sur la « structure des droits » est incompatible avec les valeurs autochtones. Comment surmonter ces objections en apparence inébranlables? Le problème des femmes autochtones est-il simplement une affaire de « droits » non reconnus? N’est-ce pas plutôt un problème de rapports de pouvoir à l’extérieur, mais également à l’intérieur, des communautés? Nous tentons dans ce qui suit de démontrer qu’au-delà d’un cadre théorique basé sur les droits de la personne, une approche basée sur le principe démocratique permettrait aux femmes autochtones de faire valoir leurs revendications en tant que femmes et en tant qu’autochtones d’une manière plus efficace. En effet, la participation démocratique de tous les membres de la communauté permettrait de contourner les problèmes théoriques liés à une dichotomie entre droits individuels et collectifs, en mettant l’accent sur le processus décisionnel plutôt que sur la valeur des décisions en découlant. Dans cette perspective, féminisme et revendications autochtones peuvent s’allier avantageusement.

Economic Impacts Of Air Pollution on Human Health and Property Values

The objectives of the present study are to provide a systematic descriptive documentation of the nature of air pollution of the Cochin industrial agglomeration, estimate the willingness to pay for morbidity reduction due to air pollution in observed and hypothetical markets and to estimate the value of welfare loss in the purchase of property due to reduced air quality. This study is an attempt to examine economic impacts of air pollution on the human health and property values in the industrial capital of Kerala. The process of industrialization in Kerala and the increase in air pollution created damages to human, natural and economic resources in the state. The study documents the extent of air pollution and applied econometric approaches to estimate economic impacts of air pollution on human health and property values. The Important sources of air pollution identified in Cochin are emissions from industries and automobiles.

Power characteristics of dielectric optical piet hein waveguides

A fairly rigorous analytical treatment of the power characteristics of dielectric optical waveguides with Piet Hein core-cross sectional geometry is presented in this paper. This kind of wareguide structure would be advantageous owing to the absence of corners, which are found in rectangular guides, resulting in undesirable loss (hit to the scattering of light. In order to simplify this theoretical approach. em approximation of vanishing refractive index difference between the guiding and the non-guiding sections is implemented. The variation eJ logarithmic power is shown for different dimensions of the core, corresponding to different azimuthal modal indices. It is found that the nutlet with higher index values carry less logaritlunic power in the lower tail of the propagation 's constant range, and this feature affects the higher tail. A better kind of uniformity of the power distribution is observed near the higher tail of the range of propagation Constants

Field Equilibrium Finite Elements for Structural Analysis

Many finite elements used in structural analysis possess deficiencies like shear locking, incompressibility locking, poor stress predictions within the element domain, violent stress oscillation, poor convergence etc. An approach that can probably overcome many of these problems would be to consider elements in which the assumed displacement functions satisfy the equations of stress field equilibrium. In this method, the finite element will not only have nodal equilibrium of forces, but also have inner stress field equilibrium. The displacement interpolation functions inside each individual element are truncated polynomial solutions of differential equations. Such elements are likely to give better solutions than the existing elements.In this thesis, a new family of finite elements in which the assumed displacement function satisfies the differential equations of stress field equilibrium is proposed. A general procedure for constructing the displacement functions and use of these functions in the generation of elemental stiffness matrices has been developed. The approach to develop field equilibrium elements is quite general and various elements to analyse different types of structures can be formulated from corresponding stress field equilibrium equations. Using this procedure, a nine node quadrilateral element SFCNQ for plane stress analysis, a sixteen node solid element SFCSS for three dimensional stress analysis and a four node quadrilateral element SFCFP for plate bending problems have been formulated.For implementing these elements, computer programs based on modular concepts have been developed. Numerical investigations on the performance of these elements have been carried out through standard test problems for validation purpose. Comparisons involving theoretical closed form solutions as well as results obtained with existing finite elements have also been made. It is found that the new elements perform well in all the situations considered. Solutions in all the cases converge correctly to the exact values. In many cases, convergence is faster when compared with other existing finite elements. The behaviour of field consistent elements would definitely generate a great deal of interest amongst the users of the finite elements.

Studies on Non-Resonant Multiphoton Processes in Atomic Hydrogen

In the present thesis we have formulated the Dalgarno-Lewis procedure for two-and three-photon processes and an elegant alternate expressions are derived. Starting from a brief review on various multiphoton processes we have discussed the difficulties coming in the perturbative treatment of multiphoton processes. A small discussion on various available methods for studying multiphoton processes are presented in chapter 2. These theoretical treatments mainly concentrate on the evaluation of the higher order matrix elements coming in the perturbation theory. In chapter 3 we have described the use of Dalgarno-Lewis procedure and its implimentation on second order matrix elements. The analytical expressions for twophoton transition amplitude, two-photon ionization cross section, dipole dynamic polarizability and Kramers-Heiseberg are obtained in a unified manner. Fourth chapter is an extension of the implicit summation technique presented in chapter 3. We have clearly mentioned the advantage of our method, especially the analytical continuation of the relevant expressions suited for various values of radiation frequency which is also used for efficient numerical analysis. A possible extension of the work is to study various multiphoton processcs from the stark shifted first excited states of hydrogen atom. We can also extend this procedure for studying multiphoton processes in alkali atoms as well as Rydberg atoms. Also, instead of going for analytical expressions, one can try a complete numerical evaluation of the higher order matrix elements using this procedure.

Investigatins on Broadband Planar Dipole Antennas

This thesis Entitled Investigations on Broadband planar Dipole Antennas. An antenna is a device ordinarily used for both transmitting and receiving electromagnetic energy. It is an integral part of the radio communication system and accounts for a good deal of progress that has been made in this field during the last few decades.The effect of flaring the dipole arms is studied in Section 4.1. It is observed that the flaring modifies the impedance characteristics of the dipole. In particular, the change in the reactive part of the impedance with frequency is controlled considerably. This improves the 2:1 VSWR bandwidth of the antenna. The effect of various other design parameters on the impedance bandwidth of the antenna are also studied. The important conclusion drawn is that, there is considerable improvement in the impedance bandwidth of the dipole when ground arm dimensions are larger than the main arm dimensions. Theoretical analysis of various cavity backed antennas are given in Chapter 6. The experimental values agree well with the computation. Also the theory gives a clear inside view and explains the reasons for bandwidth enhancement due to flaring and end-loading of the dipole arms. The percentage bandwidth is determined by calculating the Q of the antenna. Since the approach is for the analysis of microstrip antenna on thick grounded substrate, this method cannot be used to predict the impedance bandwidth of the antennas without cavity backup. Also, the structures analysed are simplified versions of the optimised ones. Specially, the arms overlapping is neglected in the analysis. Also, the antennas with symmetrical arms can only be analysed with this theory.

Comment on "Reappraisal of experimental values of third-order elastic constants of some cubic semiconductors and metals"

In a recent paper A. S. Johal and D. J. Dunstan [Phys. Rev. B 73, 024106 (2006)] have applied multivariate linear regression analysis to the published data of the change in ultrasonic velocity with applied stress. The aim is to obtain the best estimates for the third-order elastic constants in cubic materials. From such an analysis they conclude that uniaxial stress data on metals turns out to be nearly useless by itself. The purpose of this comment is to point out that by a proper analysis of uniaxial stress data it is possible to obtain reliable values of third-order elastic constants in cubic metals and alloys. Cu-based shape memory alloys are used as an illustrative example.

Studies on nonlinear dynamics of certain reaction systems

The nonlinear dynamics of certain important reaction systems are discussed and analysed in this thesis. The interest in the theoretical and the experimental studies of chemical reactions showing oscillatory dynamics and associated properties is increasing very rapidly. An attempt is made to study some nonlinear phenomena exhibited by the well known chemical oscillator, the BelousovZhabotinskii reaction whose mathematical properties are much in common with the properties of biological oscillators. While extremely complex, this reaction is still much simpler than biological systems at least from the modelling point of view. A suitable model [19] for the system is analysed and the researcher has studied the limit cycle behaviour of the system, for different values of the stoichiometric parameter f, by keeping the value of the reaction rate (k6) fixed at k6 = l. The more complicated three-variable model is stiff in nature.
