Avaliação da viabilidade econômica do pagamento pelos serviços ambientais (PSA) na Bacia do Ribeirão do Cipó, manancial estratégico de Poços de Caldas-MGREIS, Edson Augusto dos 25 July 2014 (has links)
O objeto de estudo desta pesquisa foi à bacia hidrográfica do Ribeirão do Cipó, manancial do Município de Poços de Caldas em Minas Gerais, com os seguintes objetivos: (I) Caracterizar o atual uso e ocupação do solo da bacia hidrográfica; (II) Avaliar a Disposição a Pagar da população poços caldense pelos Serviços Ambientais providos pela bacia hidrográfica; (III) Estabelecer e simular cenários econômicos hipotéticos de Pagamento pelos Serviços Ambientais providos pela bacia hidrográfica; (IV) Avaliar a viabilidade econômica de implantar o Pagamento por Serviço Ambiental no município. A partir da organização, interpretação e manipulação em ambiente Sistema de Informação Geográfica de imagens do satélite Landsat P6 do Instituto Nacional de Pesquisa Espacial – INPE referentes ao dia 01/09/2013, foi possível caracterizar e medir, em hectares, os principais usos e ocupação das terras da bacia em estudo. Através de uma amostragem estatística da população de 151.449 habitantes da cidade, selecionadas aleatoriamente nas sete áreas de ponderação estabelecidas pelo Instituto Brasileiro de Geografia e Estatística - IBGE e utilizadas no Plano Diretor da cidade, 335 entrevistas diretas foram realizadas com a população tendo como base um questionário com 14 perguntas as quais abordaram características socioeconômicas, aspectos ambientais e a disposição a pagar pelos serviços ambientais. Cenários econômicos hipotéticos foram elaborados para que fosse possível confrontar os valores obtidos com pagamento pelo Serviço Ambiental pelo Custo de Oportunidade econômica dos proprietários, permitindo, assim uma avaliação de viabilidade econômica. Os resultados obtidos foram os seguintes: (I) dos 7.752 hectares de área da bacia hidrográfica, destaca-se: 30,2% mata nativa, 29,3% solo exposto, 23,8% cultivo de Eucalipto, 4,9% de água no reservatório e corpos d’água; (II) 54% da população esta disposta a pagar pelos serviços ambientais com uma disposição econômica média de R$ 6,43. (III) Os cenários econômicos (1) e (3) ficam abaixo do custo de oportunidade enquanto que os Cenários (2) e (4) apresentam uma atratividade por incorporarem o custo de oportunidade dos proprietários. (IV) Por fim, são apresentadas as conclusões sobre a viabilidade econômica de implantar o Pagamento por Serviço Ambiental na bacia do ribeirão do Cipó, com objetivo de internalizar as externalidades positivas dos Serviços Ambientais do manancial, para proteção e garantia da provisão de água para o município no médio e longo prazo. / The object of this research was the Cipo River watershed, strategic water source of Pocos de Caldas city in Minas Gerais state, with the following objectives: (I) characterize the current land use and occupation of the watershed; (II) Assess Willingness to Pay- WTP from the Pocos de Caldas’ population for Environmental Services- ES provided by the watershed; (III) Establishing and simulate hypothetical economic scenarios for Payment for Environmental Services; (IV) Evaluate the economic feasibility of deploying the PSE in the municipality. From the organization, interpretation and manipulation in Geographic Information System- GIS from images of Landsat satellite P6 of INPE - National Institute for Space Research regarding the day 09/01/2013, it was possible to characterize and measure in hectares the main uses and occupation of the lands for watershed. Through a statistical sample of the population of 151,449 inhabitants of the city, selected randomly in seven Weighting Areas-WA established by IBGE and based in the Master Plan for the city, 335 direct interviews were conducted with the population based on a questionnaire with 14 questions that addressed socioeconomic characteristics, environmental aspects and the WTP for ES. Thus, (4) four hypothetical economic scenarios were developed to confront the values ??obtained with the PSE face the Economic Opportunity Cost of the owners allowing an evaluation of economic viability. The results obtained were as follows: (I) of the 7,752 hectares of the watershed area, stands out: 30.2% native vegetation, exposed soil 29.3%, 23.8% cultivation of Eucalyptus, 4.9% of water in the reservoir and water bodies; (II) 54% of the population is willing to pay for ES with an average WTP of R$ 6.43. (III) The economic scenarios (1) and (3) are below the Opportunity Cost while the scenarios (2) and (4) present an appeal by incorporating the opportunity cost of the owners. (IV) Finally, conclusions about the economic feasibility of deploying PSE in Cipo River watershed basin in order to internalize the positive externalities of the ES from the water source for the protection and assurance of water supply for the city in the medium and long term.

Beyond prostate-specific antigen: alternatives for prostate neoplasm screeningYu, Kevin Kuo-Han 12 March 2016 (has links)
Prostate adenocarcinoma (PCa) is one of the most prevalent cancers in the world. Second only to lung cancer, the key to its successful treatment is in its early detection. With the introduction of prostate-specific antigen in the early 1990s, a screening test involving measuring levels of this protein was developed to detect PCa in asymptomatic individuals. This test is also known as the PSA test. PCa-specific mortalities have been in decline since the test's introduction.
Despite this decline, recent studies have called the efficacy of the PSA test into question. Two large randomized controlled trials conducted in the US and Europe reveal contradicting results as to PSA's accuracy and usefulness. Concerns of overdiagnosis and overtreatment as the result of using PSA screening has led to many national organizations recommending caution or even recommending against its use. Through a thorough review of a large collection of current PCa literature, this study reviews the flaws of using PSA to screen for PCa and investigates alternative approaches currently being pursued through active research to make PCa early detection more accurate. These approaches include improving the accuracy of the PSA screen using PSA-derived testing methods, using PCa-induced epigenetic modifications as a new target for PCa screening, and using urine biomarkers. All of these methods were compared using area under the curve (AUC) values obtained via receiver operating characteristic analysis.
Each method has its own flaws but by comparing each of the different approaches, I was able to conclude that out of the currently available screening methods, screening for Engrailed-2 protein in urine is the most promising screening method with the highest AUC values compared to the other methods. Although this method has been introduced in the UK, it has not been introduced in the US yet. Epigenetic screening methods hold the most promise for accurate PCa screening in the future as it confers the highest accuracy in detecting PCa. However, as it hasn't been shown that epigenetic modifications can be easily obtained in the urine or blood serum for easy and accurate screening, I believe more work has to be done in order for it to be successful in being applied as a screening test. By determining the most promising screening type, we can focus resources and efforts towards finding a way to detect PCa early, allowing for successful treatment.

Personalisation of web information search: an agent based approachGopinathan-Leela, Ligon, n/a January 2005 (has links)
The main purpose of this research is to find an effective way to personalise information
searching on the Internet using middleware search agents, namely, Personalised Search
Agents (PSA). The PSA acts between users and search engines, and applies new and existing
techniques to mine and exploit relevant and personalised information for users.
Much research has already been done in developing personalising filters, as a middleware
technique which can act between user and search engines to deliver more personalised results.
These personalising filters, apply one or more of the popular techniques for search result
personalisation, such as the category concept, learning from user actions and using metasearch
engines. By developing the PSA, these techniques have been investigated and
incorporated to create an effective middleware agent for web search personalisation.
In this thesis, a conceptual model for the Personalised Search Agent is developed,
implemented by developing a prototype and benchmarked the prototype against existing web
search practices. System development methodology which has flexible and iterative
procedures that switch between conceptual design and prototype development was adopted as
the research methodology.
In the conceptual model of the PSA, a multi-layer client server architecture is used by
applying generalisation-specialisation features. The client and the server are structurally the
same, but differ in the level of generalisation and interface. The client handles personalising
information regarding one user whereas the server effectively combines the personalising
information of all the clients (i.e. its users) to generate a global profile. Both client and server
apply the category concept where user selected URLs are mapped against categories. The
PSA learns the user relevant URLs both by requesting explicit feedback and by implicitly
capturing user actions (for instance the active time spent by the user on a URL). The PSA also
employs a keyword-generating algorithm, and tries different combinations of words in a user
search string by effectively combining them with the relevant category values.
The core functionalities of the conceptual model for the PSA, were implemented in a
prototype, used to test the ideas in the real word. The result was benchmarked with the results
from existing search engines to determine the efficiency of the PSA over conventional
searching. A comparison of the test results revealed that the PSA is more effective and
efficient in finding relevant and personalised results for individual users and possesses a
unique user sense rather than the general user sense of traditional search engines.
The PSA, is a novel architecture and contributes to the domain of knowledge web information
searching, by delivering new ideas such as active time based user relevancy calculations,
automatic generation of sensible search keyword combinations and the implementation of a
multi-layer agent architecture. Moreover, the PSA has high potential for future extensions as
well. Because it captures highly personalised data, data mining techniques which employ
case-based reasoning make the PSA a more responsive, more accurate and more effective tool
for personalised information searching.

Adhésifs nanostructurés en voie émulsionDeplace, Fanny 11 April 2008 (has links) (PDF)
Nous avons étudié les propriétés d'adhésion et de déformation de films de polymères adhésifs préparés à partir de particules de latex nanostructurées. Une méthodologie basée sur deux critères rhéologiques et applicable à tout type de PSA a été proposée pour optimiser les performances adhésives. Elle nous a permis d'identifier des stratégies permettant d'améliorer le compromis entre propriétés adhésives et cohésives dans le cas particulier de PSA préparés à partir de particules de latex ayant une morphologie cœur-écorce. Une stratégie intéressante est l'activation d'une réaction de réticulation interparticule pendant le séchage du latex. Nous avons fait varier l'hétérogénéité du réseau tout en gardant constante la composition en monomères. Nous avons montré l'effet remarquable de cette réaction de réticulation sur les propriétés en grandes déformations de nos matériaux. Ces propriétés sont assez bien décrites par un modèle non-linéaire combinant le modèle de Maxwell sur convecté et le modèle de Gent. Les meilleurs résultats d'adhésion sont obtenus pour des matériaux caractérisés par un net ramollissement à déformations intermédiaires suivi d'un rhéodurcissement. Ce comportement est notamment obtenu pour des PSA préparés à partir de particules de latex ayant une fine écorce assez réticulée et un cœur très mou. Dans un registre plus industriel, des performances adhésives prometteuses ont été obtenues avec des PSA préparés à partir de latex tackifiés in situ synthétisés par polymérisation en miniémulsion.

A population-based family study of prostate cancer in an era of prostate-specific antigen testingStaples, Margaret Patricia Unknown Date (has links) (PDF)
Familial aggregation of prostate cancer has been demonstrated in studies conducted in a number of countries prior to the widespread adoption of prostate-specific antigen (PSA) testing for prostate cancer detection. PSA testing leads to over-diagnosis of asymptomatic disease that may not have become clinically significant within a man’s normal lifetime. This increase in the number of asymptomatic men diagnosed might alter the magnitude of familial risk estimates and the importance of a prostate cancer family history.

Posouzení rizik jaderné elektrárny Temelín / Safety assessment of Temelin NPPKOŠŤÁL, Jaroslav January 2015 (has links)
History of peaceful use of nuclear energy, despite of all necessary emphasis on operation safety, is accompanied by a series of accidents, some of which left indelible trace in minds of wide public and so led to changes in the comprehension of nuclear safety and in the access to its preservation. Because the consequences of possible nuclear power plant accident have always serious social impacts, it is most desirable to define all possibly risks, to quantify probability of their formation and in this way to gain the possibility to prevent them effectively and efficiently. This work is dedicated to approve or to disapprove that the KARS method is practically applicable for evaluation of nuclear power station operation safety. The work objective is to evaluate events and risks associated with the operation of a particular nuclear facility by the KARS method and critically evaluate obtained results and the used method as such. The work is divided into theoretical and practical part. Theoretical part includes basic information necessary for correct understanding of the chosen data processing procedure and subsequent interpretation of the gained results. A brief overview of basic concepts relating to the nuclear safety, the safety culture and the emergency preparedness, including their definitions is given in this section of the work. For the evaluation of obtained results it is useful to make familiar with basic concepts of the NPP safety evaluation, PSA and the stress tests. Obviously, it is necessary to describe the KARS method and to define the concept of quality of human performance with regard to the obtained results. The risk analysis by the KARS method was carried out in the four consecutive steps: 1. Data collection for the risk analysis. 2. Data processing by the use of the KARS method. 3. Interpretation of the obtained results. 4. Comparison of the obtained results with the available data. The particular risks for the construction of the risk correlation table were based on the analysis of activities of individual members of the emergency and technical support center on the basis of managing documentation for each function. In the emergency instructions these risks are either named or the action to manage them are determined. Subsequently these risks are further more specify according to the operational documentation used for solving abnormal and emergency conditions or solving of severe accidents. Determination of the risk correlation seems to be subjective and requires a considerable degree of professional insight into the analyzed issues. The risk analysis was processed according to the procedure that was laid down by Ing. Stefan Pacinda, Ph.D. Each risk taken into consideration in this analysis is briefly described within the interpretation of obtained results. The coefficients of activity with the biggest value were found for these risks: human error, earthquake, plane crash, terrorist threat, errors in operating and managing documentation and fire. The coefficients of passivity with the biggest value were found for these risks: human failure, serious damage to health, ecological disaster, components malfunctions, radiation accident, nuclear material integrity damage and control system malfunctions. Comparison of the risks that were postulated in the stress tests and the risks that were considered in this analysis indicate that the ETE NPP emergency response was prepared to be able to cope these risks. Results of this analysis showed that the essential element for the safe operation of nuclear power plants is qualified, well selected and systematically trained staff. In light of the experience acquired during elaboration of this work I have concluded that the KARS method can be used for nuclear safety evaluation only in a limited way.

Previous issue date: 2016-09-15 / This thesis aims to analyze the process of Workforce Movement's emergence and elaboration in Amazonas in early 1930s. This period was characterized by the rise of Getulio Vargas as president of the provisional Government. Amazonas, in this context, lived the reordering of its political forces. The fading of the oligarchic system, gave oppotunity to the projection of a new regional political leadership of Vargas' projects. At the same time, we were living important changes in the relationship between governments and unions, indicated by the foundation of the Ministry of Labor, Industry and Commerce in late 1930. Since then, the union movement becomes better observed by some political leaders who, in Amazonas, came to align themselves with this segment, and in some cases, acted as agents of Vargas policy with workers' organizations. In this context, some leaders such as Álvaro Botelho Maia and Luís Tirelli begin to stand out in the local political context. The Partido Socialista Amazonense (PSA) and the Partido Trabalhista Amazonense (PTA) respectively, their performances were extremely important in aggregating the main political forces of that period in Amazonas. Their performances in the elections of 1933, 1934 and 1935 highlighted as political party agents, at first in antagonistic positions, and then, under one party - Partido Popular Amazonense - (PPA) - became allies of the Getulio Vargas' proposals. In this scenario, Tribuna Popular newspaper's foundation, first as the PTA disclosure institution and subsequently linked to the PPA, is revealed as an important information source in that period, and the aforementioned party leaders. Its periodicity between 1933 and 1936, not only allows to build the constitution of the political Amazonas profile, but also alert us to their other function, which was to offer itself as a place for the labor proposals draft their proposals, concerns and discussions about some of the people involved in the workforce and trade union world at that time. / Esta dissertação tem por objetivo analisar o processo de surgimento e gestação do Movimento Trabalhista no Estado do Amazonas, por volta da primeira metade da década de 1930. Esse período seria caracterizado pelos desdobramentos, em todo país, da ascensão de Getúlio Vargas como presidente do então Governo Provisório. O Amazonas, sob tal contexto, assistiria ao reordenamento de suas forças políticas. O enfraquecimento do sistema oligárquico oportunizaria a projeção de novas lideranças políticas regionais que, naquele momento, colocavam-se à disposição dos projetos pretendidos por Vargas. Ao mesmo tempo, vivenciaríamos ali importantes transformações nas relações entre governos e sindicatos, indicadas pela criação do Ministério do Trabalho, Indústria e Comércio em fins de 1930. A partir de então, o movimento sindical passa a ser melhor observado por algumas lideranças políticas que, no caso do Amazonas, alinham-se com esse segmento, chegando, em alguns casos, a atuarem como agentes da política varguista junto às organizações de trabalhadores. Nesse contexto, algumas lideranças como Álvaro Botelho Maia e Luís Tirelli passam a destacar-se no quadro político local. À frente do Partido Socialista Amazonense (PSA) e do Partido Trabalhista Amazonense (PTA), respectivamente, suas atuações foram fundamentais em agregarem em torno de si as principais forças políticas daquele período no Estado. Seus desempenhos nos processos eleitorais de 1933, 1934 e 1935 destacaram-nos enquanto agentes político-partidários, num primeiro momento em posições antagônicas para, logo em seguida, sob uma única legenda – o Partido Popular Amazonense (PPA) - seguirem como aliados em torno das propostas de Getúlio Vargas. Em meio a esse cenário, a fundação do periódico Tribuna Popular, primeiro como órgão de divulgação do PTA e, posteriormente, vinculado ao PPA, revela-se como uma fonte primorosa sob o período e as lideranças partidárias acima mencionadas. Sua periodicidade entre os anos de 1933 e 1936, além de permitir traçar a constituição do perfil político do Amazonas, desperta-nos para sua outra função, que era oferecer-se enquanto espaço para que as propostas Trabalhistas pudessem, ao longo desses anos, esboçarem suas propostas, anseios e discussões sobre parte do mundo operário e sindical da época.
