Validation des produits d'inversion des observations satellitaires CALIPSO/CloudSat pour la caractérisation des propriétés optiques et microphysiques des nuages de glace et en phase mixte

Mioche, Guillaume 30 March 2010 (has links) (PDF)
Cette thèse s'inscrit dans les projets de validation des satellites CALIPSO et CloudSat de L'A-Train dédiés à l'étude des nuages, afin d'améliorer leur représentation dans les modèles de prévision du climat. La validation a consisté à mesurer les paramètres microphysiques et optiques des nuages au moyen d'instruments in situ aéroportés (PMS, Néphélomètre Polaire,CPI). Plusieurs campagnes ont été réalisées en région Arctique (ASTAR 2007 et POLARCAt) et en cirrus aux latitudes moyennes CIRCLE-2) au cours desquelles les observations in situ ont été colocalisées avec celles des satellites. La méthode de traitement du CPI a été améliorée pour la restitution des paramètres microphysiques et du facteur de réflectivité radar (Z). Concernant la validation de CLIPSO, deux situations en cirrus montrent un bon accord entre les coefficients d'extinction (sigma) in situ et restitués, validant ainsi les hypothèses dans l'inversion du lidar. Pour une autre situation, l'effet d'orientation de cristaux de forme plane et hexagonale conduit à des réflexions spéculaire du faisceau lidar et à une surestimation de sigma restitué. A l'opposé des valeurs in situ de sigma plus élevées que CALIOP sont observées lors d'une situation de cirrus avec des cristaux de grande dimension. Les effets de fragmentation de ces cristaux peuvent se traduire par la génération de petites particules avec pour conséquence une surestimation de sigma mesurée. Quant à la validation de CloudSat les résultats montrent un bon accord entre Z CloudSat at ZCPI. En revanche, les parammètres nuageux restitués sont largement surestimés en particulier dans les nuages mixtes où le schéma d'inversion basé sur la température est mal adapté

Validity of the California Psychological Inventory for Police Selection

Hwang, Guo Shwu-Jen 05 1900 (has links)
The study examined the validity of using the California Psychological Inventory (CPI) as a tool for police selection. The mean CPI profile of 211 police applicants was first compared to that of the CPI norms. Five performance criterion measures--retention on the job, academy grades, supervisory ratings, commendations, and reprimands of police officers--were studied to investigate their relationships with the CPI scales. The results indicated that there were significant mean differences on all the CPI scales between police applicants and CPI norms. The scale of Flexibility significantly differentiated the criterion groups of retention on the job. The CPI was useful in predicting academy performance; however, it did not correlate well with job performance as measured by supervisory ratings, commendations, and reprimands.

"Prevalência das doenças periodontais em pacientes com doença isquêmica coronariana aterosclerótica, em Hospital Universitário" / Prevalence of periodontal diseases in patients with ischaemic coronary disease in an University Hospital, 2003.

Barilli, Ana Lucia de Azevedo 06 February 2003 (has links)
As doenças periodontais (DP) são precedidas em importância apenas pela cárie dentária como problema de saúde bucal coletiva no Brasil. Ambas são doenças infecciosas ainda muito prevalentes, entretanto é dada às DP uma importância questionavelmente secundária, pois não são sistematicamente investigadas e prevenidas em saúde pública. Pelo fato de sua prevalência ser atualmente desconhecida no Brasil, a alta freqüência das formas leves e moderadas das doenças periodontais na população como um todo e de suas formas mais graves em grupos ou indivíduos de risco, dentre estes os portadores de cardiopatias isquêmicas, motivou este estudo no Ambulatório de Cardiopatia Isquêmica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, cotejando os resultados com outros obtidos em grupo de pessoas não-cardiopatas atendidas na mesma instituição. Foi investigada a prevalência e gravidade das doenças periodontais, bem como a prevalência de seus fatores de risco, história médica da presença de doenças de interesse à periodontia (diabetes, hipertensão, acidente vascular cerebral) e comportamento relativo à higiene bucal. Dentre as 634 pessoas examinadas na fase de recrutamento dos participantes, 480 foram do grupo de pacientes cardiopatas isquêmicos e 154 de grupo de não-cardiopatas. Foram selecionados respectivamente de cada grupo, 58 e 62 participantes, na faixa etária de 30 a 79 anos, para a investigação periodontal. A média da idade foi de 53 anos em ambos os sexos para os pacientes cardiopatas e de 40 anos nos homens e 37 anos nas mulheres nos pacientes não-cardiopatas. Foram utilizados o Índice Periodontal Comunitário (IPC) e o índice de Perda de Inserção periodontal (PI), ambos recomendados pela OMS (1999). Os resultados mostraram um predomínio de sextantes nos escores indicativos das formas graves da DP entre os pacientes cardiopatas (74,1% contra 20,2%; p < 0,00001). Dentre os pacientes cardiopatas apenas 1,1% dos sextantes exibiram saúde periodontal, contra 32,0% nos pacientes não-cardiopatas (p < 0,00001). No tocante a história pregressa da DP, mensuradas através da perda de inserção, 6,0% dos sextantes não a exibiram entre os pacientes cardiopatas, contra 68,0% dos não-cardiopatas (p < 0,00001). Eram portadores de fatores de retenção de biofilme dental 100,0% dos pacientes cardiopatas e 82,3% dos pacientes não-cardiopatas (p < 0,001). Exigiam tratamento periodontal mais complexo, normalmente praticados por especialistas em periodontia, 94,8% dos pacientes cardiopatas contra 33,9% dos pacientes não-cardiopatas (p < 0,0001). Necessitavam de tratamento de bolsas > 6mm 79,3% dos pacientes cardiopatas contra 9,7% dos pacientes não-cardiopatas (p < 0,0001). Alguns fatores de risco comprovado e/ou provável às DP, foram investigados nos pacientes cardiopatas e pacientes não-cardiopatas: observou-se tabagismo em 10,4% e 33,9% (p < 0,01), respectivamente; alcoolismo em 44,8% e 24,2% (p < 0,02), respectivamente; diabetes em 29,3% e 1,6% (p < 0,0001), respectivamente; hipertensão arterial em 34,5% e 8,1% (p < 0,001), respectivamente. Conclusões: As DP mostraram-se muito prevalentes nos dois grupos estudados, sendo de maior gravidade nos pacientes com cardiopatia isquêmica. A elevada prevalência de fatores de risco às DP aponta para a necessidade de adoção de estratégias de intervenção para minimizá-los. / Periodontal diseases are preceded in importance only by dental caries as oral public health problem in Brazil. Both are infectious diseases and with high prevalences, however, a secondary importance is given to periodontal diseases because they are not routinely investigated and prevented at public health level. Presently its prevalence is not known in the Brazilian population. The high prevalence of mild and moderate forms of periodontal diseases in the general population, and its severe forms in specific groups or in high risk patients, as those with ischaemic coronary diseases, motivated this survey. It was carried out among patients from the Outpatient Clinic of Ischaemic Coronary Disease – Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo – and using for comparisons patients from other clinics of the same hospital. The prevalence and severity of periodontal diseases were investigated, as well as the prevalence of their risk factors, medical history of diseases with periodontic interest (diabetes, hypertension, stroke), and behaviour related to oral hygiene. During the recruitment phase, among 634 patients examined, 480 were from the group with cardiopathy and 154 from the group without cardiopathy. From each group were selected, respectively, 58 and 62 participants, aged 30 to 79 years for the periodontal investigation. Mean age was 53 years for both sexes in the group with cardiopathy and 40 years for men and 37 years for women in the group without cardiopathy. The Community Periodontal Index and the Attachment Periodontal Index, both recommended by the World Health Organization (1999), were used. Results showed a predominance of sextants in the scores indicating severe forms of periodontal diseases among patients with cardiopathy (74.1 vs. 20.2%; p< 0.00001). Among patients with cardiopathy, only 1.1% of the sextants showed periodontal health against 32.0% in the other group (p< 0.00001). Previous history of periodontal diseases, measured through lost of insertion, was present in 6.0% of the sextants in patients with cardiopathy and 68.0% in those without cardiopathy (p< 0.0001). All patients with cardiopathy and 82.3% of those without cardiopathy were carriers of retention factors of dental biofilm (p< 0.001). It was found that 94.8% of the patients with cardiopathy against 33.9% of the other group (p< 0.0001) required more complex periodontal treatment, usually performed by periodontal specialists. Treatment of sites &#8805; 6mmm was required by 79.3% of the patients with cardiopathy and by 9.7% from the other group (p< 0.0001). The frequency of confirmed or possible risk factors for periodontal diseases in the groups with and without cardiopathy were, respectively: smoking – 10.4 and 33.9% (p< 0.001); alcoholism – 44.8 and 24.2% (p< 0.02); diabetes – 29.3 and 1.6% (p< 0.0001); hypertension – 34.5 and 8.1% (p< 0.001). Conclusions: Periodontal diseases were highly prevalent in the two groups studied, but with higher severity among patients with cardiopathy. The high frequency of risk factors for periodontal diseases in both groups appointed to the need of intervention strategies towards these risk factors.

The first step is to identify the origins and sources of the power of these committees. This is done through the analysis of some of the fundamental principles of the Democratic State of Right instituted by the 1988 Federal Constitution. The following step is to know which are the tools that the Congressional Investigation Committees can use in order to accomplish their mission, and which are the limits of their action, given that there are no unlimited powers under the. The Parliament is the locus of the Congressional Investigation Committees. They constitute a fundamental tool for the exercise of the investigation of the public administration. This investigation function is part of the ordinary competence of oversight which is constitutionally and exclusively conferred to the Legislative Power / O presente trabalho tem como objeto a identificação e o estudo dos aspectos considerados mais relevantes do instituto das comissões parlamentares de inquérito no contexto do ordenamento jurídico brasileiro, permitindo compreender quais são as normas jurídicas vigentes aplicáveis bem como, em alguns casos, a interpretação dessas normas pelo Supremo Tribunal Federal. De início, procura-se identificar as origens e as fontes do poder que as comissões parlamentares de inquérito exercem mediante a análise de alguns dos princípios fundamentais no Estado Democrático de Direito instituído pela Constituição Federal de 1988. Identificada as origens e as fontes desse poder, procura-se conhecer quais são os instrumentos colocados à disposição das comissões parlamentares de inquérito para o cumprimento de sua missão, assim como os limites que são impostos à sua atuação, tendo em vista que não há poderes ilimitados no Estado Democrático de Direito. Encravadas no Parlamento, entende-se aqui que as comissões parlamentares de inquérito constituem instrumento fundamental para o exercício da função investigativa das ações patrocinadas pela Administração Pública, função esta inserida na competência típica de fiscalização atribuída com exclusividade constitucional ao Poder Legislativo

A epidemiologia da saúde bucal dos povos indígenas no Brasil ainda é pouco conhecida. Os dados disponíveis, em geral, são pertinentes às zonas urbanas. As informações sobre a epidemiologia dessas doenças no Parque Indígena do Xingu (PIX) resultam de investigações nas quais foram utilizadas diferentes metodologias de coletas e análises de dados, dificultado assim um adequado panorama epidemiológico. A partir da implantação do Distrito Sanitário Especial Indígena do Xingu (DSEI-Xingu), em 1999, foram realizados três inquéritos epidemiológicos para doenças bucais, baseados na metodologia proposta pela OMS. O presente estudo teve como objetivo analisar a epidemiologia das referidas doenças no PIX, especificamente de quatro aldeias de diferentes etnias, considerando as necessidades assistenciais odontológicas. Para tal, foi realizado um estudo epidemiológico descritivo, utilizando dados secundários colhidos pela equipe do DSEI-Xingu, provenientes de inquéritos realizados em três momentos distintos: 2001, 2003 e 2006. Foram utilizados:o índice CPO-D, para avaliação da experiência de cárie e para aferir a doença periodontal, o índice periodontal comunitário (IPC). A análise dos resultados mostrou que nas aldeias estudadas, o principal problema de saúde bucal é a cárie, atingindo no ano de 2006, 81% da população. Em relação à cárie, nota-se uma queda nas médias do CPO-D para a maioria das faixas etárias no ano de 2006 em relação a 2001 e houve melhora também nos percentuais de pessoas livres de cárie para as idades entre 0 e 19 anos. As médias de ceo-d para o grupo etário de 0 a 3 anos apresentam elevação no período, exceto na aldeia Moigu, que mostrou diminuição de 8,0 em 2001 para 1,8, em 2006. Ao se analisar os componentes do CPO-D e ceo-d, quando comparados os dados obtidos em 2006 e 2001, foi possível verificar que o componente \"cariado\" apresentou redução para a maioria das faixas etárias em todas as aldeias, assim como o aumento dos componentes \"obturados e perdidos\". Observou-se que para a dentição decídua o componente cariado possui grande contribuição no ceo-d em todas as aldeias, variando entre 69% a 86% do índice. Isso traduz dificuldades no acesso dessa população aos serviços odontológicos. O índice IPC mostrou aumento do percentual de pessoas sem doença periodontal em todas as aldeias, queda no percentual de pessoas com algum tipo de bolsa periodontal e cálculo como o principal problema. Em relação às necessidades de tratamento verificou-se que restaurações foram as indicações mais freqüentes e houve um aumento no número de dentes sem nenhuma necessidade. Para a doença periodontal, observou-se que mais de 80% das pessoas acima de 15 anos precisam de tratamento e necessidade de profilaxia; as necessidades por cuidados mais complexos representam apenas 3% . Concluímos que no período de 2001 a 2006,houve uma melhoria nas condições de saúde bucal dessas populações. Uma hipótese explicativa seria a estruturação do programa de saúde bucal nestas áreas. / There is a lack of information about the epidemiology of oral health conditions of the Indian population in Brazil. In general, available data are related to urban regions. Information about the epidemiology of oral health in the Xingu Indian Park (PIX) derive from surveys that employed different methodologies for collecting and analyzing the data, making it difficult to have an adequate picture of the problem. Since the creati of the indian Special Sanitary District of Xingu (DSEIXingu) in 1999, three epidemiologic surveys for oral health were carried out, based on the methodology proposed by the World Health Organization - WHO. The present study analyzed the oral health conditions in four villages of the PIX, considering treatment needs. A descriptive study was performed, using data already collected by surveys carried out by the health team of the DSEI-Xingu, employing the same methodology, in the years 2001, 2003 ead 2006. The DMF-T index was used to avaluate the caries experience, and for periodontal disease, the community periodontal index (CPI). The analisys of the results showed that the main oral health problem in the studied villages was tooth decay, reaching 81% of the population in 2006. In relation to caries, it was observed a decline in the mean of the DMF-T for majority of the age-groups in 2006 in relation to 2001 and an improvement in the proportion of people free of caries for the ages between 0-19 years. The mean of the dmf-t for the 0 to 3 year age-group was higher in 2006, except in the Moigu village, where a decline was observed (from 8.0 in 2001 to 1.8 in 2006). Comparing the DMF-T and dmf-t between 2006 and 2001, it was observed that the component \" decayed\" decreased in most of the age-groups in the four villages, as well as an increase in the component \"filled and missing\". For the deciduous teeth, the component \"decayed\" had greater contribution in the dmft in all the villages. The CPI index showed an increase in the proportionof persons without periodontal disease and a decrease in the proportion of persons with some kind of periodontal pockets in all the villages. Calculus was the main problem. In relation to treatments needs, indication of restoration was the most frequent and there was a increase in the number of teeth without any need. For periodontal disease, more than 80% of the persons aged 15 years or more need treatment and professional tooth cleaning; more complex treatment was required only by 3% of the individuals. We concluded that there was an improvement in the oral health conditions of this population, in the period 2001 to 2006. an explanatory hypothesis for this findings could be the implementation of the strutured oral health program in this region.

As doenças periodontais (DP) são precedidas em importância apenas pela cárie dentária como problema de saúde bucal coletiva no Brasil. Ambas são doenças infecciosas ainda muito prevalentes, entretanto é dada às DP uma importância questionavelmente secundária, pois não são sistematicamente investigadas e prevenidas em saúde pública. Pelo fato de sua prevalência ser atualmente desconhecida no Brasil, a alta freqüência das formas leves e moderadas das doenças periodontais na população como um todo e de suas formas mais graves em grupos ou indivíduos de risco, dentre estes os portadores de cardiopatias isquêmicas, motivou este estudo no Ambulatório de Cardiopatia Isquêmica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, cotejando os resultados com outros obtidos em grupo de pessoas não-cardiopatas atendidas na mesma instituição. Foi investigada a prevalência e gravidade das doenças periodontais, bem como a prevalência de seus fatores de risco, história médica da presença de doenças de interesse à periodontia (diabetes, hipertensão, acidente vascular cerebral) e comportamento relativo à higiene bucal. Dentre as 634 pessoas examinadas na fase de recrutamento dos participantes, 480 foram do grupo de pacientes cardiopatas isquêmicos e 154 de grupo de não-cardiopatas. Foram selecionados respectivamente de cada grupo, 58 e 62 participantes, na faixa etária de 30 a 79 anos, para a investigação periodontal. A média da idade foi de 53 anos em ambos os sexos para os pacientes cardiopatas e de 40 anos nos homens e 37 anos nas mulheres nos pacientes não-cardiopatas. Foram utilizados o Índice Periodontal Comunitário (IPC) e o índice de Perda de Inserção periodontal (PI), ambos recomendados pela OMS (1999). Os resultados mostraram um predomínio de sextantes nos escores indicativos das formas graves da DP entre os pacientes cardiopatas (74,1% contra 20,2%; p < 0,00001). Dentre os pacientes cardiopatas apenas 1,1% dos sextantes exibiram saúde periodontal, contra 32,0% nos pacientes não-cardiopatas (p < 0,00001). No tocante a história pregressa da DP, mensuradas através da perda de inserção, 6,0% dos sextantes não a exibiram entre os pacientes cardiopatas, contra 68,0% dos não-cardiopatas (p < 0,00001).

Treatment of sites &#8805; 6mmm was required by 79.3% of the patients with cardiopathy and by 9.7% from the other group (p< 0.0001). The frequency of confirmed or possible risk factors for periodontal diseases in the groups with and without cardiopathy were, respectively: smoking – 10.4 and 33.9% (p< 0.001); alcoholism – 44.8 and 24.2% (p< 0.02); diabetes – 29.3 and 1.6% (p< 0.0001); hypertension – 34.5 and 8.1% (p< 0.001). Conclusions: Periodontal diseases were highly prevalent in the two groups studied, but with higher severity among patients with cardiopathy. The high frequency of risk factors for periodontal diseases in both groups appointed to the need of intervention strategies towards these risk factors.

Decision Support System for the Evaluation and Comparison of Concession Project Investments

McCowan, Alison Kate, n/a January 2004 (has links)
Governments of developed and developing countries alike are unable to fund the construction and maintenance of vital physical infrastructure such as roads, railways, water and wastewater treatment plants, and power plants. Thus, they are more and more turning to the private sector as a source of finance through procurement methods such as concession contracts. The most common form of concession contract is the Build-Operate-Transfer (BOT) contract, where a government (Principal) grants a private sector company (Promoter) a concession to build, finance, operate and maintain a facility and collect revenue over the concession period before finally transferring the facility, at no cost to the Principal, as a fully operational facility. Theoretically speaking, these projects present a win-win-win solution for the community as well as both private and public sector participants. However, with the opportunity for private sector companies to earn higher returns comes greater risk. This is despite the fact that concession projects theoretically present a win-win-win solution to the problem of infrastructure provision. Unfortunately, this has not been the case in a number of countries including Australia. Private sector participants have admitted that there are problems that must be addressed to improve the process. Indeed they have attributed the underperformance of concession projects to the inability of both project Principals and Promoters to predict the impact of all financial and non-financial (risk) factors associated with concession project investments (CPIs) and to negotiate contracts to allow for these factors. Non-financial project aspects, such as social, environmental, political, legal and market share factors, are deemed to be important; but these aspects would usually be considered to lie outside the normal appraisal process. To allow for the effects of such qualitative aspects, the majority of Principal or promoting organisations resort to estimating the necessary money contingencies without an appropriate quantification of the combined effects of financial and non-financial (risks and opportunities) factors. In extreme cases, neglect of non-financial aspects can cause the failure of a project despite very favourable financial components; or can even cause the failure to go-ahead with a project that may have been of great non-financial benefit due to its projected ordinary returns. Hence, non-financial aspects need careful analysis and understanding so that they can be assessed and properly managed. It is imperative that feasibility studies allow the promoting organisation to include a combination of financial factors and non-financial factors related to the economic environment, project complexity, innovation, market share, competition, and the national significance of the project investment. While much research has already focused on the classification of CPI non-financial (risk) factors, and the identification of interdependencies between risk factors on international projects, no attempt has yet been made to quantify these risk interdependencies. Building upon the literature, this thesis proposes a generic CPI risk factor framework (RFF) including important interdependencies, which were verified and quantified using input provided by practitioners and researchers conversant with risk profiles of international and/or concession construction projects. Decision Support Systems (DSSs) are systems designed to assist in the decision making process by providing all necessary information to the analyst. There are a number of DSSs that have been developed over recent years for the evaluation of high-risk construction project investments, such as CPIs, which incorporate the analysis of both financial and non-financial (risk) aspects of the investment. However, although these DSSs have been useful to practitioners and researchers alike, they have not offered a satisfactory solution to the modelling problem and are all limited in their practical application for various reasons. Thus, the construction industry lacks a DSS that is capable of evaluating and comparing several CPI options, taking into consideration both financial and non-financial aspects of an investment, as well as including the uncertainties commonly encountered at the feasibility stage of a project, in an efficient and effective manner. These two criteria, efficiency and effectiveness, are integral to the usefulness and overall acceptance of the developed DSS in industry. This thesis develops an effective and efficient DSS to evaluate and compare CPI opportunities at the feasibility stage. The novel DSS design is based upon a combination of: (1) the mathematical modelling technique and financial analysis model that captures the true degree of certainty surrounding the project; and (2) the decision making technique and RFF that most closely reproduces the complexity of CPI decisions. Overall, this thesis outlines the methodology followed in the development of the DSS – produced as a stand-alone software product – and demonstrates its capabilities through a verification and validation process using real-life CPI case studies.

Oral Health Status and Treatment Needs of the Institutionalized Chronic Psychiatric Patients in two Ontario Psychiatric Care Centres Neyaz Farrahi-Avval Master of Science Graduate Department of Dentistry University of Toronto 2008 Abstract Purpose: To examine the oral health status of psychiatric in-patients at two long-term psychiatric health centres, with one operating a full-time dental care facility. Methods: Data were gathered from clinical examinations, a structured interview and hospital records from 120 participants. Periodontal (CPI) and dental (DMFT) indices, subjectively reported oral health status, and oral health behaviour were subsequently analyzed. Results: Referrals for dental problems were made for 62.9% of participants. Bivariate analyses revealed positive correlations between DMFT scores, age and length of stay. Multiple regression analyses demonstrated correlations between DMFT scores and infrequent dental visits, frequent snacking and age. Patients at the psychiatric hospital without a full-time dental care facility were more likely to have had higher DMFT scores, and infrequent dental visits. Conclusions: Psychiatric patients have poor oral health and significant oral health treatment needs. This study underlines the need for on-site dental care facilities at long-term psychiatric care centres.
