Les anthropologues ont examiné le syncrétisme religieux, soit l’incorporation d’éléments de sources diverses, au sein des religions du monde depuis plusieurs décennies. Cependant, très peu d’intérêt a été accordé au paganisme contemporain, un Nouveau Mouvement Religieux hautement syncrétique. À travers les récits de plusieurs païens/nes contemporain/es à Montréal, j’examine comment et pourquoi les pratiquants sont inspiré/es à faire le choix d’incorporer divers éléments provenant de sources religieuses et non religieuses. Le recours à des sources différentes reflète l’effort de créer une expérience religieuse plus profonde et personnelle. La créativité impliquée dans la construction d’une pratique spirituelle et d’un système de croyance personnels est souvent conduite par un désir de (re)connexion, que ce soit à la terre, aux ancêtres, ou bien à une communauté. Les acteurs acquièrent un sentiment accru d’agentivité dans ce processus. Ma participation dans cette communauté a influencé mes expériences de recherche; j’examine également ma position en tant qu’anthropologue chez soi.

To study the behaviour of beam-to-column composite connection more sophisticated finite element models is required, since component model has some severe limitations. In this research a generic finite element model for composite beam-to-column joint with welded connections is developed using current state of the art local modelling. Applying mechanically consistent scaling method, it can provide the constitutive relationship for a plane rectangular macro element with beam-type boundaries. Then, this defined macro element, which preserves local behaviour and allows for the transfer of five independent states between local and global models, can be implemented in high-accuracy frame analysis with the possibility of limit state checks. In order that macro element for scaling method can be used in practical manner, a generic geometry program as a new idea proposed in this study is also developed for this finite element model. With generic programming a set of global geometric variables can be input to generate a specific instance of the connection without much effort. The proposed finite element model generated by this generic programming is validated against testing results from University of Kaiserslautern. Finally, two illustrative examples for applying this macro element approach are presented. In the first example how to obtain the constitutive relationships of macro element is demonstrated. With certain assumptions for typical composite frame the constitutive relationships can be represented by bilinear laws for the macro bending and shear states that are then coupled by a two-dimensional surface law with yield and failure surfaces. In second example a scaling concept that combines sophisticated local models with a frame analysis using a macro element approach is presented as a practical application of this numerical model.

In this work, we have mainly achieved the following: 1. we provide a review of the main methods used for the computation of the connection and linearization coefficients between orthogonal polynomials of a continuous variable, moreover using a new approach, the duplication problem of these polynomial families is solved; 2. we review the main methods used for the computation of the connection and linearization coefficients of orthogonal polynomials of a discrete variable, we solve the duplication and linearization problem of all orthogonal polynomials of a discrete variable; 3. we propose a method to generate the connection, linearization and duplication coefficients for q-orthogonal polynomials; 4. we propose a unified method to obtain these coefficients in a generic way for orthogonal polynomials on quadratic and q-quadratic lattices. Our algorithmic approach to compute linearization, connection and duplication coefficients is based on the one used by Koepf and Schmersau and on the NaViMa algorithm. Our main technique is to use explicit formulas for structural identities of classical orthogonal polynomial systems. We find our results by an application of computer algebra. The major algorithmic tools for our development are Zeilberger’s algorithm, q-Zeilberger’s algorithm, the Petkovšek-van-Hoeij algorithm, the q-Petkovšek-van-Hoeij algorithm, and Algorithm 2.2, p. 20 of Koepf's book "Hypergeometric Summation" and it q-analogue.

TCP flows from applications such as the web or ftp are well supported by a Guaranteed Minimum Throughput Service (GMTS), which provides a minimum network throughput to the flow and, if possible, an extra throughput. We propose a scheme for a GMTS using Admission Control (AC) that is able to provide different minimum throughput to different users and that is suitable for "standard" TCP flows. Moreover, we consider a multidomain scenario where the scheme is used in one of the domains, and we propose some mechanisms for the interconnection with neighbor domains. The whole scheme uses a small set of packet classes in a core-stateless network where each class has a different discarding priority in queues assigned to it. The AC method involves only edge nodes and uses a special probing packet flow (marked as the highest discarding priority class) that is sent continuously from ingress to egress through a path. The available throughput in the path is obtained at the egress using measurements of flow aggregates, and then it is sent back to the ingress. At the ingress each flow is detected using an implicit way and then it is admission controlled. If it is accepted, it receives the GMTS and its packets are marked as the lowest discarding priority classes; otherwise, it receives a best-effort service. The scheme is evaluated through simulation in a simple "bottleneck" topology using different traffic loads consisting of "standard" TCP flows that carry files of varying sizes

La presente monografía busca establecer una conexión argumentada entre la expedición de la ley 200 de 1936 y la creación de Autodefensas Campesinas en la primera mitad del siglo XX en Colombia. Se buscan las razones estructurales por las cuales la sociedad rural se vio abocada a impulsar agrupaciones armadas para defender sus derechos fundamentales, debido a que el Estado demostró ser incapaz de protegerlos mientras que el odio entre clases rurales aumentó conforme se implementaba el capitalismo agrario en el país. Desde la Teoría del Conflicto de Clases Rurales de Jeffery Paige, se explicará la forma en la que se articulan las variables que no permiten una revolución social, pero si propician la aparición de este tipo de grupos campesinos armados e ilegales; que luego se transformarían en “Guerrillas”.

This paper proposes a look at museums from the perspective of sociomuseology, an area of research and practice under development in countries such as Portugal, Brazil and Spain. Sociomuseology was born from the Latin new museology tradition and is closely connected with the International Movement for a New Museology (MINOM/ICOM). The Lusofona University in Lisbon offers MA and PhD programmes in Sociomuseology. The University supports a research centre in Sociomuseology and publishes the journals Cadernos de Sociomuseologia, in Portuguese, and Sociomuseology, in English (for more information see http://tercud.ulusofona.pt.). Sociomuseology concerns the study of the social role of museums and of the continuous changes in society that frame their trajectories. The practice of sociomuseologists is based on their work with the different dimensions of social and community development from ecomuseums to networking and other ways of organizing social action in the 21st century in which heritage plays a strategic role.

Using an idealized primitive equation model, we investigate how stratospheric conditions alter the development of baroclinic instability in the troposphere. Starting from the lifecycle paradigm of Thorncroft et al., we consider the evolution of baroclinic lifecycles resulting from the addition of a stratospheric jet to the LC1 initial condition. We find that the addition of the stratospheric jet yields a net surface geopotential height anomaly that strongly resembles the Arctic Oscillation. With the additional modification of the tropospheric winds to resemble the high-AO climatology, the surface response is amplified by a factor 10 and, though dominated by the tropospheric changes, shows similar sensitivity to the stratospheric conditions.
