Globalization and Orthodox Christianity: A Glocal Perspective

This article analyses the topic of Globalization and Orthodox Christianity. Starting with Victor Roudometof’s work (2014b) dedicated to this subject, the author’s views are compared with some of the main research of social scientists on the subject of sociological theory and Eastern Orthodoxy. The article essentially has a twofold aim. Our intention will be to explore this new area of research and to examine its value in the study of this religion and, secondly, to further investigate the theory of religious glocalization and to advocate the fertility of Roudometof’s model of four glocalizations in current social scientific debate on Orthodox Christianity

Multimode network representation of two dimensional steps in rectangular waveguides

In this paper a new Multimode Network representation for arbitrary rectangular waveguide junctions is presented. The energy coupling between the higher order modes excited in the junction is rigorously described via a multimode impedance matrix representation that can be used to build very efficient and accurate software tools for the analysis of complex structures. The elements of the impedance matrix are obtained from the solution of an integral equation. The main feature of the approach is that the kernel of the integral equation derived is essentially independent from frequency and therefore, the most time consuming task, namely the solution of the integral equation, need to be performed only once per each geometry. The formulation of the method is discussed and the form of the integral equation is given, showing explicitly the dependence with the frequency. A frequency extraction procedure that can lead to a considerable time saving for the analysis of complex structures is also discussed. Finally the design of a commercial communication satellite filter structure is presented, including comparisons between our analysis and measurements of the manufactured hardware

Novel design procedure for microwave filters

In this paper a novel design procedure is described for the hardware implementation of microwave filters. The procedure is based on a very accurate and efficient software package for the full-wave simulation of the structure and consists of a step-by-step procedure that systematically leads to dimensioning of the mplete filter geometry. Following the procedure described, each successive step only involves the dimensioning of a maximum of four physical parameters. As an illustrative example, the design of a nine pole non-uniform filter is discussed indicating how the procedure is indeed very efficient

Multimode synthesis procedure for microwave filters based on thick inductive windows

For several types of microwave filters for space application it is important to manufacture hardware without tuning elements. For this to be possible, one needs a systematic procedure to codvert ideal elements, such as resonators and impedance inverters, into actual waveguide lengths and discontinuities. The situation is further complicated by the fact that waveguide discontinuities excite higher order modes that interacting with each other can have very strong effects. In this paper we first outline the theory behind a very efficient computer code for the simulation of microwave filters based on thick inductive windows. Then we describe in detail a step-by-step procedure that, based on the code developed, allows for the rapid design of this class of microwave filters without any tuning elements. Two actual examples of design are also discussed and comparisons presented between measurements and simulations

Multimode Network Analysis of Planar Transmission Lines

An alternative approach for the full wave analysis of single or coupled planar transmission lines is presented. Following the proposed approach, a multiple (or single) transmission line structure is viewed as series of staked (or single) transverse discontinuities in a parallel plate waveguide. As a consequence, both top and side coupled structures can be studied. Each individual discontinuity is described in terms of a multimode equivalent network representation. The complete cross section of the planar transmission line structure is then described in terms of a transverse equivalent network and a simple transverse resonance technique is then used to obtain the dispersion behavior, the modal field of the structure, and the characteristic impedances. The multimode equivalent network representations of the individual discontinuities used in this paper have been derived else where and are given in terms of impedance or admittance matrices that are essentially independent from frequency. As a result, they need to be computed only once for each given geometry thus leading to codes that are computationally very efficient.European Space Agenc

Rigorous, Multimode Equivalent Network Representation of Capacitive Discontinuities

In this paper we present novel, rigorous, multimode equivalent network representations for a variety of zero-thickness capacitive windows and obstacles in a parallel plate waveguide. A key feature of these representations is that the coupling between all of the modes excited is described by a matrix whose elements do not depend on frequency or absolute dimensions. The value of the results presented is that the networks developed can be used to analyze rigorously a large variety of single and coupled planar transmission line structures.European Space Agenc

GLOCALIZAÇÃO RELIGIOSA E MIGRAÇÃO NA ITÁLIA: O CENÁRIO RELIGIOSO ITALIANO ENTRE CONTINUIDADES E MUDANÇAS

Neste artigo desenvolvemos a noção de glocalização religiosa para examinar as religiões de imigrantes. Compreendemos os enraizamentos das comunidades imigrantes no contexto receptor no sentido de hibridização. Desenvolvendo quatro principais padrões de glocalização religiosa (indigenização, vernacularização, nacionalização e transnacionalização) nós as assumimos como conceitos-chave para a análise do estabelecimento das comunidades religiosas. Adotamos esse modelo no caso da Itália, enfatizando recentes trajetórias desse cenário religioso. Em síntese, esse artigo busca sublinhar uma perspectiva religiosa glocal sobre religiões de imigrantes e sugerimos algumas variações sobre religião e migração na Itália

New Simple Procedure for the Computation of the Multimode Admittance or Impedance Matrix of Planar Waveguide Junctions

Much effort has been devoted in the past to the development of electromagnetic simulation algorithms for wave- guide junctions that could at the same time include higher-order mode interactions and lead to computationally efficient codes. Even though this is indeed a classical subject, there is still a strong interest in this area as waveguide systems become increas- ingly complex, and ever shorter development and manufacturing times are required. In this paper a simple method is described for the evaluation of the multimode network representation of planar waveguide junctions in terms of admittance or impedance parameters. The key feature of the method is that it starts from the wanted final results, the equivalent network representation, in order to obtain an analytic expression for the evaluation of the relevant matrix elements. The procedure is based on general network theory and is equivalent to ideally measuring directly the value of the admittance or impedance elements. In this paper the evaluation procedure is fully described. Measured results of actual hardware are then compared with simulations indicating that the codes developed are indeed very accurate as well as computationally very efficient.Agencia Espacial Europe

Job Insecurity and Job Performance: A Serial Mediated Relationship and the Buffering Effect of Organizational Justice

The study aimed to extend the current knowledge of the relationship between job insecurity and performance. In line with traditional stress theories, work-family and burnout were hypothesized as serial mediators of the negative link between job insecurity and job performance. Also, the current study hypothesized that the association between job insecurity and the mediators [i.e., Work-family conflict (WFC) and burnout] could be buffered by perceived organizational justice among employees. Therefore, we empirically tested a moderated serial mediation model. Participants were 370 employees of an Italian multiservice social cooperative. Data were collected using a self-report questionnaire in the aftermath of the COVID-19 pandemic outbreak. The obtained results indicated that WFC and burnout mediated the association between job insecurity and job performance. Furthermore, perceived organizational justice buffered the relationship between job insecurity and WFC. Concerning job burnout, the association with job insecurity was moderated only among employees perceiving medium and high levels of organizational justice. The moderated serial mediation index provided support to the role of organizational justice in decreasing the association between job insecurity and job performance. This study delves deeper into the variables explaining the relationship between job insecurity and job performance by testing a serial process mechanism that involved WFC and burnout. Additionally, the obtained results provide suggestions to organizations and managers regarding the protective role of organizational justice to sustain employees\u2019 mental health and performance. Practical implications at the organizational and managerial level are provided, along with a focus on the actual impact of the pandemic
