Weak Zone Related Seismic Cycles in Progressive Failure Leading to Collapse in Brittle Crust

Until quite recently our understanding of the basic mechanical process responsible for earthquakes and faulting was not well known. It can be argued that this was partly a consequence of the complex nature of fracture in crust and in part because evidence of brittle phenomena in the natural laboratory of the earth is often obliterated or obscured by other geological processes. While it is well understood that the spatial and temporal complexity of earthquakes and the fault structures emerge from geometrical and material built-in heterogeneities, one important open question is how the shearing becomes localized into a band of intense fractures. Here the authors address these questions through a numerical approach of a tectonic plate by considering rockmass heterogeneity both in microscopic scale and in mesoscopic scale. Numerical simulations of the progressive failure leading to collapse under long-range slow driving forces in the far-field show earthquake-like rupture behavior. $En Echelon$ crack-arrays are reproduced in the numerical simulation. It is demonstrated that the underlying fracturing induced acoustic emissions (or seismic events) display self-organized criticality------from disorder to order. The seismic cycles and the geometric structures of the fracture faces, which are found greatly depending on the material heterogeneity (especially on the macroscopic scale), agree with that observed experimentally in real brittle materials. It is concluded that in order to predict a main shock, one must have extremely detailed knowledge on very minor features of the earth's crust far from the place where the earthquake originated. If correct, the model proposed here seemingly provides an explanation as to why earthquakes to date are not predicted so successfully. The reason is not that the authors do not understand earthquake mechanisms very well but that they still know little about our earth's crust.

Product aesthetics: representing designer intent and consumer response

This thesis reports on the development of a conceptual framework for product aesthetics. By adopting the theoretical perspective that products are a medium of communication between designers and consumers, the nature of consumer response and designer intent is explored. By integrating a range of disparate literature within a single coherent framework, the varieties of consumer response to product visual form are illustrated. To investigate the ways in which designers intend to evoke these responses, a qualitative research study was undertaken. This primarily involved interviews with industrial designers and consumer investigators. Analysis of these interviews led to the development of a conceptual framework for designer intent which both mirrors, and integrates with, that produced for consumer response. By representing processes beyond design that are influential in determining product form, a broader contextual framework is presented within which product aesthetics is situated. In concluding the thesis, applications for this framework are discussed and future research directions are proposed.

The island of Kauai, Hawaii's progressive shoreline setback and coastal protection ordinance

Approximately two-thirds of coastal and Great Lakes states have some type of shoreline construction setback or construction control line requiring development to be a certain distance from the shoreline or other coastal feature (OCRM, 2008). Nineteen of 30 coastal states currently use erosion rates for new construction close to the shoreline. Seven states established setback distances based on expected years from the shoreline: the remainder specify a fixed setback distance (Heinz Report, 2000). Following public hearings by the County of Kauai Planning Commission and Kauai County Council, the ‘Shoreline Setback and Coastal Protection Ordinance’ was signed by the Mayor of Kauai on January 25, 2008. After a year of experience implementing this progressive, balanced shoreline setback ordinance several amendments were recently incorporated into the Ordinance (#887; Bill #2319 Draft 3). The Kauai Planning Department is presently drafting several more amendments to improve the effectiveness of the Ordinance. The intent of shoreline setbacks is to establish a buffer zone to protect shorefront development from loss due to coastal erosion - for a period of time; to provide protection from storm waves; to allow the natural dynamic cycles of erosion and accretion of beaches and dunes to occur; to maintain beach and dune habitat; and, to maintain lateral beach access and open space for the enjoyment of the natural shoreline environment. In addition, a primary goal of the Kauai setback ordinance is to avoid armoring or hardening of the shore which along eroding coasts has been documented to ultimately eliminate the fronting beach.

Progressive Decrease in the Potential Usefulness of Meningococcal Serogroup B Vaccine (4CMenB, Bexsero (R)) in Gipuzkoa, Northern Spain

The effectiveness of a vaccine is determined not only by the immunogenicity of its components, but especially by how widely it covers the disease-causing strains circulating in a given region. Because vaccine coverage varies over time, this study aimed to detect possible changes that could affect vaccine protection during a specific period in a southern European region. The 4CMenB vaccine is licensed for use in Europe, Canada, and Australia and is mainly directed against Neisseria meningitidis serogroup B. This vaccine contains four main immunogenic components: three recombinant proteins, FHbp, Nhba and NadA, and an outer membrane vesicle [PorA P1.4]. The allelic distribution of FHbp, Nhba, NadA, and PorA antigens in 82 invasive isolates (B and non-B serogroups) isolated from January 2008 to December 2013 were analyzed. 4CMenB was likely protective against 61.8% and 50% of serogroup B and non-B meningococci, respectively, in the entire period, but between 2012 and 2013, the predicted protection fell below 45% (42.1% for serogroup B isolates). The observed decreasing trend in the predicted protection during the 6 years of the study (X-2 for trend = 4.68, p=0.03) coincided with a progressive decrease of several clonal complexes (e. g., cc11, cc32 and cc41/44), which had one or more antigens against which the vaccine would offer protection.

Deus, o diabo e a televisão: mídia moderna de massa e pentecostalismo em uma comunidade evangélica da Ilha Grande

O foco desta dissertação é a relação entre Pentecostalismo e a tecnologia televisiva na vila de Provetá, uma comunidade evangélica situada na Ilha Grande, município de Angra dos Reis, Estado do Rio de Janeiro. Os residentes de Provetá são majoritariamente membros da Igreja Pentecostal Assembléia de Deus, situada ali desde princípios da década de 1930. A televisão, em contraste, fora introduzida na vila apenas em 1987, mediante o acesso a antenas parabólicas. O objetivo central da dissertação é compreender o processo histórico e social de inserção da tecnologia televisiva na vila de Provetá, e como esta tecnologia se relaciona com mídias e práticas Pentecostais de mediação com o transcendental. Condenada num primeiro momento pelo então pastor presidente da Assembléia de Deus como uma tecnologia exclusivamente diabólica e portanto, irrevogavelmente proibida aos membros da igreja , a televisão fora progressivamente ressignificada pelas lideranças da igreja como uma tecnologia ambivalente, a partir da qual tanto Deus quanto o Diabo seriam capazes de operar. A dissertação explora, nesse sentido, o processo de negociação em torno dos significados religiosos atribuídos à televisão, bem como os regimes normativos relativos ao seu consumo. Dado o status ambivalente da tecnologia televisiva aos olhos das lideranças contemporâneas da igreja seu potencial de estar a serviço de Deus ou do Diabo, do bem ou do mal , busco compreender uma ética do assistir que parece subjazer o processo de autorização do consumo da televisão, isto é, como um crente deve assisti-la. Assistir à televisão de forma eticamente apropriada, portanto, implicaria um conhecimento essencial sobre como assistir. Este conhecimento, argumento, é o conhecimento da Bíblia. Mediante um regime de verdade bíblico, os provetaenses traçariam uma distinção fundamental em relação aos conteúdos televisivos considerados factuais ou reais, cujo consumo seria inofensivo ou benéfico, e aqueles considerados forjados, encenados ou construídos, cujo consumo seria inapropriado, ou ainda perigoso. Partindo da identificação das telenovelas da Rede Globo como mentiras de natureza diabólica, e do telejornal como um espaço de aprendizado para o crente, empreendo uma análise de recepção destes programas, buscando compreender as dinâmicas simbólicas e sensoriais de identificação das presenças e das agências de Deus e do Diabo através da televisão. O argumento central a ser desenvolvido na dissertação é o de que a experiência de assistir à televisão em Provetá encontra-se estruturada por uma estética Pentecostal fomentada a partir da Bíblia. A partir das práticas religiosas de mediação centradas na Bíblia, um regime sensorial Pentecostal fora progressivamente constituído: uma dada gramática do sentir os objetos da experiência em relação ao regime de verdade Bíblico. Têm-se, desse modo, uma dinâmica circular no interior da qual imagens são experimentadas sensivelmente a partir do prisma da verdade Bíblica, e tais sensações, por sua vez, objetificam a realidade dessa verdade no corpo do sujeito. Nessa dialética entre o crer e o sentir, a experiência sensível de assistir à televisão é informada por um entendimento Pentecostal da realidade, e esse entendimento é autenticado por aquilo que é sentido.
