Valor intrínseco na bioética ambiental: uma análise crítica das concepções de Dworkin, Singer e Rolston III
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2010O tema desta dissertação é o valor intrínseco e sua aplicabilidade no contexto da bioética ambiental. Discute-se, sobretudo, as concepções de valor intrínseco apresentadas por Ronald Dworkin, Peter Singer e Holmes Rolston III. Tais autores possuem concepções de valor intrínseco diversas e delas realizam diferentes usos e aplicações, o que origina o problema desta pesquisa, levando-nos a questionar se tais concepções de valor intrínseco realmente são suficientes para se propor uma teoria bioética ambiental. A hipótese considerada é a de que dependendo do conceito e do uso da expressão "valor intrínseco", a concepção adotada pelos filósofos não é suficientemente adequada para fundamentar ou, pelo menos, apoiar a construção de uma proposta de ética ambiental que garanta individualmente igual proteção às mais diversas formas de vida. Assim, o objetivo consiste em analisar diversos usos e aplicações de concepções de valor intrínseco na ética prática e, mais especificamente, verificar os limites dessas concepções na sua aplicação no contexto de teorias bioéticas. A partir disso, aponta-se para uma concepção de "valor inerente" para a qual uma ética ambiental genuína deve voltar-se, sem descartar as contribuições de Dworkin, Singer e Rolston III. Para tanto, defende-se a importância de superar uma visão representacionista de mundo, segundo a qual os seres humanos são concebidos enquanto entidades separadas do restante do mundo natural, substituindo-a por uma concepção de natureza que entende os seres humanos como parte do mundo natural, que, por sua vez, é continuamente construído pela interação mente e mundo
Uporaba razširjene resničnosti za upravljanje in vzdrževanje hidroelektrarn
No full textThe hydropower plants are increasingly constructed and managed on a building information modelling (BIM) platform and operations are getting automated for better performance. With the energy market getting competitive due to the technological advancements in the solar and wind power sector, even the ageing power plants are also upgraded with the latest technologies to maintain their competitiveness as cheap and clean energy. But the maintenance and inspection are still carried out manually using the conventional method of using paper-based manuals, 2D drawings and specifications. Therefore, Augmented reality (AR) is one of the promising technologies for cognitive assistance in a complex working environment that requires manual input. The thesis focuses on the potential of AR technologies for the maintenance and inspection of power plants. It highlights the requirement and challenges to implement AR in power plants with and without 3D BIM models as the methodology is different. The AR can facilitate the operators to better understand the task to be performed or the condition of the components by displaying the virtual information such as instructions, faulty components, analysed data and other relevant information superimposed with the real object/scene. The information can be presented in a structured way for better comprehension which would improve performance. The introduction of new technologies to the workplace would face initial reluctance and challenges to train the workforce. The benefits would be noticed when the users are conversant with the technology.Informacijsko modeliranje zgradb (BIM) se je v zadnjem času uveljavilo, kot standarden način projektiranja gradbenih objektov – tudi hidro-energetskih, ki predstavljajo poseben izziv skozi celoten življenski cikelj, še posebej pa v fazi upravljanja in vzdrževanja. Tudi starejši hidro-energetski objekti se nadgrajujejo z najsodobnejšimi tehnologijami s ciljem zagotavljanja čiste in poceni električne energije. Razvoj tehnologij industrije 4.0 je obogočil nove priložnosti naprednejšega upravljanja s hidro-energetskimi objekti v fazi uporabe ter vzdrževanja z vključevanjem tehnologij umetne inteligence in drugih digitalnih tehnologij. Razširjena resničnost (angl. Augmented reallity - AR) je ena izmed informacijskih tehnologij, ki odpiraja nove možnosti kognitivne pomoči uporabnikom v različnih industrijskih. Cilj raziskave je poročati in oceniti potencial in izzive uporabe razširjene resničnosti v kontekstu vzdrževanja in upravljanja hidro-energetskih objektov. Pri tem sta obravnavana dva osnovna uporabniška scenarija za uporabo razširjene resničnosti: (1) primer sodobnih hidro-energetskih objektov za katere je izdelan model BIM ter (2) starejše hidro-energetske objekte za katere model BIM ni dostopen. Raziskava je pokazala, da lahko razširjena resničnost prispeva k učikovitejšemu upravljanju in vzdrževanju obravnavanih objektov
Oblivious Algorithms for the Max-kAND Problem
No full textMotivated by recent works on streaming algorithms for constraint satisfaction problems (CSPs), we define and analyze oblivious algorithms for the Max-kAND problem. This is a class of simple, combinatorial algorithms which round each variable with probability depending only on a quantity called the variable’s bias. Our definition generalizes a class of algorithms defined by Feige and Jozeph (Algorithmica '15) for Max-DICUT, a special case of Max-2AND.
For each oblivious algorithm, we design a so-called factor-revealing linear program (LP) which captures its worst-case instance, generalizing one of Feige and Jozeph for Max-DICUT. Then, departing from their work, we perform a fully explicit analysis of these (infinitely many!) LPs. In particular, we show that for all k, oblivious algorithms for Max-kAND provably outperform a special subclass of algorithms we call "superoblivious" algorithms.
Our result has implications for streaming algorithms: Generalizing the result for Max-DICUT of Saxena, Singer, Sudan, and Velusamy (SODA'23), we prove that certain separation results hold between streaming models for infinitely many CSPs: for every k, O(log n)-space sketching algorithms for Max-kAND known to be optimal in o(√n)-space can be beaten in (a) O(log n)-space under a random-ordering assumption, and (b) O(n^{1-1/k} D^{1/k}) space under a maximum-degree-D assumption. Even in the previously-known case of Max-DICUT, our analytic proof gives a fuller, computer-free picture of these separation results
A importância moral da dor e do sofrimento animal na ética de Peter Singer
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2012.O objetivo desta dissertação é defender a importância moral da consideração da dor e do sofrimento de animais não-humanos. Isso se dá através do principio da igual consideração de interesses desenvolvido por Peter Singer. A senciência possibilita os animais a terem interesses, no mínimo, o interesse evitar a dor e o sofrimento. É por essa razão que devem ser incluídos nas decisões morais. São reconstruídas e analisadas as objeções de Peter Harrison, Carl Cohen, R.G. Frey e Lawrence C. Becker direcionadas ao princípio de Singer, e que criticam os pressupostos básicos, quais sejam, a capacidade de sentirem dor/sofrimento e de terem interesses, sobre os quais se fundamenta a inclusão dos animais nas considerações morais. Cada uma dessas objeções é analisada e criticada de modo a demonstrar suas limitações e inconsistências, juntamente com as implicações morais geradas para seres humanos. Na análise dessas críticas, reforça-se a importância e a consideração moral que deve ser conferida à dor e ao sofrimento dos animais. Após essa discussão teórica, é analisado um caso de âmbito prático: a pesquisa científica sobre o câncer humano através do modelo animal. Verifica-se, a partir do princípio de Singer, a imoralidade de tal procedimento realizado em animais sencientes devido à violação de seus interesses. Com isso, a dissertação enfatiza a exigência ética de abolir o uso de animais nessa prática em razão da incapacidade preditiva dos animais, mas principalmente devido à dor e ao sofrimento causado neles e também aos seres humanos, que ficam sujeitos aos erros, prejuízos e sofrimentos originados pelo intenso uso animal nas pesquisas. Nessa conclusão, se constata que a insistência no uso de animais nos experimentos compromete o cientista a preferir usar seres humanos, uma vez que isso gera mais benefícios e resultados mais seguros. A recusa moral ao uso de humanos em pesquisas implica, por outro lado, na recusa moral do uso de animais, ou seja, sua abolição.Abstract : The aim of this dissertation is to defend the moral importance of considering pain and suffering of nonhuman animals. This is achieved through The Principle of Equal Consideration of Interests developed by Peter Singer. The sentience enables nonhuman animals to have interests, at least the interest of avoiding pain and suffering. That is why it should be included in moral decisions. The objections of Peter Harrison, Carl Cohen, RG Frey and Lawrence C. Becker directed to the principle of Singer are reconstructed and analyzed, as they are criticizing the basic assumptions, i.e., the ability to feel pain/suffering and have interests, upon which is based the inclusion of animals in moral considerations. Each of these objections is analyzed and criticized in order to demonstrate their limitations and inconsistencies, simultaneously with its moral implications for humans. In the analysis of these criticisms, it reinforces the moral importance and considerations that should be given to pain and suffering of animals. After this theoretical discussion, a case study of practical scope is analyzed: animal testing for scientific research on human cancer. It is verified from the Singer's principle that such procedures performed on sentient animals are a violation of their interests and, therefore, immoral. Thus, the dissertation emphasizes the ethical demand to abolish the use of nonhuman animals in this practice due to their predictive inability, but mainly due to the pain and suffering caused to them and also to humans, who are subject to errors, injuries and suffering originated by the intense use of nonhuman animals on research. The conclusion verifies that the insistence on the use of nonhuman animals in experiments moves the scientist to prefer using humans in experiments since it generates greater benefit and more reliable results. The moral refusal to using humans in research implies the moral rejection of the use of animals in experiments and consequently, its abolition
Powerful Trend Function Tests That are Robust to Strong Serial Correlation with an Application to the Prebisch Singer Hypothesis
No full textIn this paper we propose tests for hypothesis regarding the parameters of a the deterministic trend function of a univariate time series. The tests do not require knowledge of the form of serial correlation in the data and they are robust to strong serial correlation. The data can contain a unit root and the tests still have the correct size asymptotically. The tests we analyze are standard heteroskedasticity autocorrelation (HAC) robust tests based on nonparametric kernel variance estimators. We analyze these tests using the small-b asymptotic framework recently proposed by Kiefer and Vogelsang (2002). This analysis allows us to analyze the power properties of the tests with regards to bandwidth and kernel choices. Our analysis shows that among popular kernels, there are specific kernel and bandwidth choices that deliver tests with maximal power within a specific class of tests. We apply the recommended tests to the logarithm of a net barter terms of trade series and we find that this series has a statistically significant negative slope. This finding is consistent with the well known Prebisch-Singer hypothesis. Because our tests are robust to strong serial correlation or a unit root in the data, our results in support of the Prebisch-Singer hypothesis are relatively strong.Estimator, Fixed-b Asymptotics, Power Envelope, Unit Root, Nearly Integrated, Partial Sum, Deterministic Trend, Linear Trend.
