Evaluation of Potential Post-Glacial Faults Using Bare-Earth LiDAR Topographic Data Near Ridley Island, British Columbia

I present results of my evaluation to identify topographic lineaments that are potentially related to post-glacial faulting using bare-earth LiDAR topographic data near Ridley Island, British Columbia. The purpose of this evaluation has been to review bare-earth LiDAR data for evidence of post-glacial faulting in the area surrounding Ridley Island and provide a map of the potential faults to review and possibly field check. My work consisted of an extensive literature review to understand the tectonic, geologic, glacial and sea level history of the area and analysis of bare-earth LiDAR data for Ridley Island and the surrounding region. Ridley Island and the surrounding north coast of British Columbia have a long and complex tectonic and geologic history. The north coast of British Columbia consists of a series of accreted terranes and some post-accretionary deposits. The accreted terranes were attached to the North American continent during subduction of the Pacific Plate between approximately 200 Ma and 10 Ma. The terrane and post-accretionary deposits are metamorphosed sedimentary, volcanic and intrusive rocks. The rocks have experienced significant deformation and been intruded by plutonic bodies. Approximately 10 Ma subduction of the Pacific Plate beneath the North America Plate ceased along the central and north coast of British Columbia and the Queen Charlotte Fault Zone was formed. The Queen Charlotte Fault Zone is a transform-type fault that separates the Pacific Plate from the North America Plate. Within the past 1 million years, the area has experienced multiple glacial/interglacial cycles. The most recent glacial cycle occurred approximately 23,000 to 13,500 years ago. Few Quaternary deposits have been mapped in the area. The vast majority of seismicity around the northwest coast of British Columbia occurs along the Queen Charlotte Fault Zone. Numerous faults have been mapped in the area, but there is currently no evidence to suggest these faults are active (i.e. have evidence for post-glacial surface displacement or deformation). No earthquakes have been recorded within 50 km of Ridley Island. Several small earthquakes (less than magnitude 6) have been recorded within 100 km of the island. These earthquakes have not been correlated to active faults. GPS data suggests there is ongoing strain in the vicinity of Ridley Island. The strain has the potential to be released along faults, but the calculated strain may be a result of erroneous data or accommodated aseismically. Currently, the greatest known seismic hazard to Ridley Island is the Queen Charlotte Fault Zone. LiDAR data for Ridley Island, Digby Island, Lelu Island and portions of Kaien Island, Smith Island and the British Columbia mainland were reviewed and analyzed for evidence of postglacial faulting. The data showed a strong fabric across the landscape with a northwest-southeast trend that appears to mirror the observed foliation in the area. A total of 80 potential post-glacial faults were identified. Three lineaments are categorized as high, forty-one lineaments are categorized as medium and thirty-six lineaments are categorized as low. The identified features should be examined in the field to further assess potential activity. My analysis did not include areas outside of the LiDAR coverage; however faulting may be present there. LiDAR data analysis is only useful for detecting faults with surficial expressions. Faulting without obvious surficial expressions may be present in the study area.

Cytotoxicity of topical antimicrobial agents used in burn wounds in Australasia

Background: Burn sepsis is a leading cause of mortality and morbidity in patients with major burns. The use of topical antimicrobial agents has helped improve the survival of these patients. Silvazine (Sigma Pharmaceuticals, Melbourne, Australia) (1% silver sulphadiazine and 0.2% chlorhexidine digluconate) is used exclusively in Australasia, and there is no published study on its cytotoxicity. This study compared the relative cytotoxicity of Silvazine with 1% silver sulphadiazine (Flamazine (Smith & Nephew Healthcare. Hull. UK)) and a silver-based dressing (Acticoat (Smith & Nephew Healthcare, Hull, UK)). Methods: Dressings were applied to the centre of culture plates that were then seeded with keratinocytes at an estimated 25% confluence. The plates were incubated for 72 h and culture medium and dressings then removed. Toluidine blue was added to stain the remaining keratinocytes. Following removal of the dye, the plates were photographed under standard conditions and these digital images were analysed using image analysis software. Data was analysed using Student's t-test. Results: In the present study, Silvazine is the most cytotoxic agent. Seventy-two hour exposure to Silvazine in the present study results in almost no keratinocyte survival at all and a highly statistically significant reduction in cell survival relative to control, Acticoat and Flamazine (P

Approximate processing of massive continuous quantile queries over high-speed data streams

Quantile computation has many applications including data mining and financial data analysis. It has been shown that an is an element of-approximate summary can be maintained so that, given a quantile query d (phi, is an element of), the data item at rank [phi N] may be approximately obtained within the rank error precision is an element of N over all N data items in a data stream or in a sliding window. However, scalable online processing of massive continuous quantile queries with different phi and is an element of poses a new challenge because the summary is continuously updated with new arrivals of data items. In this paper, first we aim to dramatically reduce the number of distinct query results by grouping a set of different queries into a cluster so that they can be processed virtually as a single query while the precision requirements from users can be retained. Second, we aim to minimize the total query processing costs. Efficient algorithms are developed to minimize the total number of times for reprocessing clusters and to produce the minimum number of clusters, respectively. The techniques are extended to maintain near-optimal clustering when queries are registered and removed in an arbitrary fashion against whole data streams or sliding windows. In addition to theoretical analysis, our performance study indicates that the proposed techniques are indeed scalable with respect to the number of input queries as well as the number of items and the item arrival rate in a data stream.

A Bayesian hierarchical model for categorical longitudinal data from a social survey of immigrants

The paper investigates a Bayesian hierarchical model for the analysis of categorical longitudinal data from a large social survey of immigrants to Australia. Data for each subject are observed on three separate occasions, or waves, of the survey. One of the features of the data set is that observations for some variables are missing for at least one wave. A model for the employment status of immigrants is developed by introducing, at the first stage of a hierarchical model, a multinomial model for the response and then subsequent terms are introduced to explain wave and subject effects. To estimate the model, we use the Gibbs sampler, which allows missing data for both the response and the explanatory variables to be imputed at each iteration of the algorithm, given some appropriate prior distributions. After accounting for significant covariate effects in the model, results show that the relative probability of remaining unemployed diminished with time following arrival in Australia.

Extent and economic effect of heat loads on dairy cattle production in Australia

Objective To investigate the extent of heat load problems, caused by the combination of excessive temperature and humidity, in Holstein-Friesian cows in Australia. Also, to outline how milk production losses and consequent costs from this can be estimated and minimised. Procedures Long-term meteorological data for Australia were analysed to determine the distribution of hot conditions over space and time. Fifteen dairy production regions were identified for higher-resolution data analysis. Both the raw meteorological data and their integration into a temperature-humidity thermal index were compiled onto a computer program. This mapping software displays the distribution of climatic patterns, both Australia-wide and within the selected dairying regions. Graphical displays of the variation in historical records for 200 locations in the 15 dairying regions are also available. As a separate study, production data from research stations, on-farm trials and milk factory records were statistically analysed and correlated with the climatic indices, to estimate production losses due to hot conditions. Results Both milk yields and milk constituents declined with increases in the temperature-humidity index. The onset and rate of this decline are dependent on a number of factors, including location, level of production, adaptation, and management regime. These results have been integrated into a farm-level economic analysis for managers of dairy properties. Conclusion By considering the historical patterns of hot conditions over time and space, along with expected production losses, managers of dairy farms can now conduct an economic evaluation of investment strategies to alleviate heat loads. These strategies include the provision of sprinklers, shade structures, or combinations of these.

Constructing internationally comparable real income aggregates by combining sparse benchmark data with annual national accounts data: A state-space approach

The importance of availability of comparable real income aggregates and their components to applied economic research is highlighted by the popularity of the Penn World Tables. Any methodology designed to achieve such a task requires the combination of data from several sources. The first is purchasing power parities (PPP) data available from the International Comparisons Project roughly every five years since the 1970s. The second is national level data on a range of variables that explain the behaviour of the ratio of PPP to market exchange rates. The final source of data is the national accounts publications of different countries which include estimates of gross domestic product and various price deflators. In this paper we present a method to construct a consistent panel of comparable real incomes by specifying the problem in state-space form. We present our completed work as well as briefly indicate our work in progress.

O IMPACTO DA ESPIRITUALIDADE NO TRABALHO E DE PERCEPÇÃO DE SAÚDE ORGANIZACIONAL SOBRE COMPORTAMENTOS DE CIDADANIA ORGANIZACIONAL

Cada vez mais o fator humano está em evidência no mercado competitivo e globalizado. Por isso, constantemente, as empresas se preocupam com a qualidade do trabalho, para que seus colaboradores sintam prazer em sua realização, não sendo tão agredidos pelas pressões do dia a dia. Nesse contexto, esta dissertação teve como objetivo geral analisar as relações entre espiritualidade no trabalho, percepção de saúde organizacional e comportamentos de cidadania organizacional entre professores universitários. Participaram deste estudo 82 trabalhadores de ambos os sexos, com idade entre 28 e 63 anos, os quais atuam no Estado de São Paulo em Instituições de Ensino Superior públicas e privadas. Como instrumento para coleta de dados foi utilizado um questionário de autopreenchimento composto de três escalas que mediram as variáveis da pesquisa. Assim, o estudo se propôs a apresentar, interpretar e discutir as relações entre as variáveis, como também, testar hipóteses referentes ao modelo conceitual proposto, por meio de uma pesquisa com abordagem quantitativa, cujos dados coletados foram analisados por aplicação de técnicas estatísticas paramétricas (cálculo de estatísticas descritivas: médias, desvios padrão, índice de precisão de medidas, teste t e correlações; cálculos de estatísticas multivariadas: regressão linear múltipla padrão. A análise dos dados foi realizada pelo software estatístico Statistical Package for the Social Science SPSS, versão 19.0 para Windows. Os resultados obtidos demonstraram que dentre as três dimensões de comportamentos de cidadania organizacional, apenas duas divulgação da imagem da organização e cooperação com os colegas receberam impacto positivo de percepção de saúde organizacional e espiritualidade no trabalho. Para estas duas classes de ações de cidadania organizacional ficou mais evidenciado o poder de impacto no trabalho. O estudo possibilitou concluir que ações de sugestões criativas realizadas pelos empregados, não sofre influências do quanto eles acreditam que a empresa tem uma saúde satisfatória e do quanto eles vivenciam, ou não, a espiritualidade no ambiente organizacional.

Avaliação das inclinações dentárias obtidas no tratamento ortodôntico com bráquetes autoligados utilizando tomografia computadorizada

O objetivo deste trabalho foi analisar a expressão dos torques dentários em pacientes tratados com aparelhos ortodônticos fixos com bráquetes autoligados, utilizando tomografias computadorizadas. Para este estudo, foi selecionada uma amostra clínica de 10 pacientes, seguindo como critérios de inclusão, indivíduos que apresentavam dentição permanente e todos os dentes presentes, com apinhamento superior ou igual a 4 mm, tratados sem extração. Todos os pacientes foram tratados na clínica da pós-graduação em Ortodontia da Universidade Metodista de São Paulo, utilizando-se bráquetes autoligados Damon 2 ORMCO na prescrição padrão. Foram realizadas medições das inclinações dos dentes anteriores, de canino a canino, superiores e inferiores, realizadas por meio de imagens tomográficas obtidas em um tomógrafo computadorizado volumétrico NewTom, em seu modelo DVT-9000 (NIM Verona - Itália), obtidas em dois tempos: antes do início do tratamento ortodôntico (denominado de T1) e depois do tratamento ortodôntico, após a inserção do último fio de nivelamento, de calibre 0,019 x 0,025 de aço inoxidável(denominado de T2). Para auxílio destas mensurações, foi utilizado o software QR-DVT 9000 e após análise dos resultados foram aplicados testes estatíscos (testes "t" pareado e Dalberg) e observou-se que as inclinações dos dentes do segmento anterior aumentaram, principalmente, nos caninos e incisivos laterais superiores, incisivos centrais e laterais inferiores. Os dentes apresentaram valores de inclinação diferentes da prescrição, tanto no início quanto no final do tratamento, denotando a incapacidade do fio 0,019 x 0,025 de aço inoxidável em reproduzir os torques indicados na prescrição padrão utilizada neste presente estudo.(AU)
