    Naming the Church: The Representation of Two Congregations in the Media

    This study examines the portrayal of religious and ethnic group conflicts in the media using a case study in Oregon. Local newspaper reports about a struggle between the St. James Catholic Church and the San Martín Catholic Mission were analyzed using cluster criticism to identify the key terms used to communicate ideas about the two congregations to the local public. Various patterns of themes emerged, which indicate that the institutions and leaders on each side of the conflict were presented as opposing forces of hierarchy/community and logic/emotion. From this analysis it can be seen that the newspapers reporting on this conflict portrayed St. James as more of a hierarchical business structure, while San Martín was represented as a vulnerable and benevolent community. The newspaper\u27s rhetorical strategy of associating the names of the churches with certain features may have influenced local perceptions of the conflict, leading to a favorable outcome for the San Martín community.

    Salva la Iglesia: A Congregation\u27s Fight for Community

    The purpose of this study is to examine community response to crisis and the impact intercultural interactions have on the outcome of ethnic and religious group conflict. This research uses a case study focusing on the San Martín Catholic Mission in Oregon and the ways this particular community responded to the crisis of the Catholic diocese threatening to sell their property in 2010. I gathered data from a year of ethnographic fieldwork, participant observations in the setting, and in-depth interviews with six individuals involved in the church and related community groups. I then analyzed the data using the lens of social capital theory to examine the resource networks built through this event and their effect on the communities. Themes such as changing roles of immigrants and minorities in the United States, changing gender roles in community activism, and changing levels of activism after community crises are resolved emerged from this analysis, which indicate the importance of social factors in affecting community response to crisis. The findings of this case study have implications for how communities may need to adapt to the changing demographic of the United States as the Latino population increases, and it provides insight into patterns of interaction that may be seen between ethnic and religious communities in the future

    Semiclassical approximation in Batalin-Vilkovisky formalism

    Get PDF
    The geometry of supermanifolds provided with QQ-structure (i.e. with odd vector field QQ satisfying {Q,Q}=0\{ Q,Q\} =0), PP-structure (odd symplectic structure ) and SS-structure (volume element) or with various combinations of these structures is studied. The results are applied to the analysis of Batalin-Vilkovisky approach to the quantization of gauge theories. In particular the semiclassical approximation in this approach is expressed in terms of Reidemeister torsion.Comment: 27 page

    Geometry of Batalin-Vilkovisky quantization

    Full text link
    The present paper is devoted to the study of geometry of Batalin-Vilkovisky quantization procedure. The main mathematical objects under consideration are P-manifolds and SP-manifolds (supermanifolds provided with an odd symplectic structure and, in the case of SP-manifolds, with a volume element). The Batalin-Vilkovisky procedure leads to consideration of integrals of the superharmonic functions over Lagrangian submanifolds. The choice of Lagrangian submanifold can be interpreted as a choice of gauge condition; Batalin and Vilkovisky proved that in some sense their procedure is gauge independent. We prove much more general theorem of the same kind. This theorem leads to a conjecture that one can modify the quantization procedure in such a way as to avoid the use of the notion of Lagrangian submanifold. In the next paper we will show that this is really so at least in the semiclassical approximation. Namely the physical quantities can be expressed as integrals over some set of critical points of solution S to the master equation with the integrand expressed in terms of Reidemeister torsion. This leads to a simplification of quantization procedure and to the possibility to get rigorous results also in the infinite-dimensional case. The present paper contains also a compete classification of P-manifolds and SP-manifolds. The classification is interesting by itself, but in this paper it plays also a role of an important tool in the proof of other results.Comment: 13 page

    Vascular challenges from pancreatoduodenectomy in the setting of coeliac artery stenosis

    Get PDF
    Coeliac artery stenosis due to median arcuate ligament compression or atherosclerotic disease is a frequently unrecognised challenge to recovery after pancreatoduodenectomy. The described case illustrates management with intraoperative superior mesenteric artery to hepatic artery bypass graft that led to haemorrhagic challenges postoperatively but ultimately a good recovery. Aspects of preoperative diagnosis, preoperative intervention and intraoperative management options are reviewed. Surgeons need to possess these tools to prevent complications from coeliac artery stenosis when pancreatoduodenectomy is required

    Sigma-models having supermanifolds as target spaces

    Get PDF
    We study a topological sigma-model (AA-model) in the case when the target space is an (m0m1m_0|m_1)-dimensional supermanifold. We prove under certain conditions that such a model is equivalent to an AA-model having an (m0m1m_0-m_1)-dimensional manifold as a target space. We use this result to prove that in the case when the target space of AA-model is a complete intersection in a toric manifold, this AA-model is equivalent to an AA-model having a toric supermanifold as a target space.Comment: 6 pages,late

    Parallel Implementation of the PHOENIX Generalized Stellar Atmosphere Program. II: Wavelength Parallelization

    Get PDF
    We describe an important addition to the parallel implementation of our generalized NLTE stellar atmosphere and radiative transfer computer program PHOENIX. In a previous paper in this series we described data and task parallel algorithms we have developed for radiative transfer, spectral line opacity, and NLTE opacity and rate calculations. These algorithms divided the work spatially or by spectral lines, that is distributing the radial zones, individual spectral lines, or characteristic rays among different processors and employ, in addition task parallelism for logically independent functions (such as atomic and molecular line opacities). For finite, monotonic velocity fields, the radiative transfer equation is an initial value problem in wavelength, and hence each wavelength point depends upon the previous one. However, for sophisticated NLTE models of both static and moving atmospheres needed to accurately describe, e.g., novae and supernovae, the number of wavelength points is very large (200,000--300,000) and hence parallelization over wavelength can lead both to considerable speedup in calculation time and the ability to make use of the aggregate memory available on massively parallel supercomputers. Here, we describe an implementation of a pipelined design for the wavelength parallelization of PHOENIX, where the necessary data from the processor working on a previous wavelength point is sent to the processor working on the succeeding wavelength point as soon as it is known. Our implementation uses a MIMD design based on a relatively small number of standard MPI library calls and is fully portable between serial and parallel computers.Comment: AAS-TeX, 15 pages, full text with figures available at ftp://calvin.physast.uga.edu/pub/preprints/Wavelength-Parallel.ps.gz ApJ, in pres
