Aquatic ecosystems are vital to the structure and function of all environments on earth. Worldwide, approximately 95 million metric tons of fishery products are harvested from marine and freshwater habitats. A major problem in fisheries around the world is the bioethics of overfishing. A wide range of management techniques exists for fishery, managers and policy-makers to improve fishery production in the future. The best approach to limit overfishing is to have an effective, federally regulated fishery, based on environmental standards and (...) fishery carrying capacity. Soon, overfishing is more likely to cause fish scarcity than fossil fuel shortages and high energy prices for fish harvesting. However, oil and other fuel shortages are projected to influence future fishery policies and the productive capacity of the fishery industry. Overall, small-scale fishing systems are more energy efficient than large-scale systems. Aquaculture is not the solution to wild fishery production. The energy input/output ratio of aquacultural fish is much higher than that of the harvest of wild populations. In addition, the energy ratios for aquaculture systems are higher than those for most livestock systems. (shrink)

El presente artículo pretende indagar en algunos tópicos relativos a las ideas de Marx y a las de Horkheimer presentes en la obra Teología de lo político de Clodovis Boff. En este análisis se observa una referencia explícita a la ideas del padre del marxismo donde Boff se acompaña con Marx, va más allá de Marx e incluso va contra Marx. Por otro lado, es posible identificar tres afinidades electivas que permiten suponer que la interpretación que Boff realiza del marxismo (...) deviene del padre de la teoría crítica, Max Horkheimer. The article below investigates topics related to Marx's and Horhkheimer's ideas as exposed in Theology of the Political by Clodovis Boff. The analysis shows a direct reference from Boff to the father of Marxism's ideas, going along, beyond and even against Marx. On the other hand, it is possible to identify three elective affinities that make us believe that his interpretation of Marx has its origin in the father of Critical Theory's ideas, Max Horkheimer.

Carrying out analyzes of qualitative master's and doctoral research continues to be a great difficulty for researchers in training. Thus, in this writing I present an itinerary for documental studies of public policies, scientific and literary texts, based on the Ricoeurian hermeneutics of discourse, text and ideology, based on two works by the philosopher, several articles to validate the interpretive procedure; and the dialogue with contributions from the gestalt clinical discourse, as the main application of the proposal is in the (...) field of Psychology and health studies. In the script I present a dynamic structure composed of three interconnected steps: identification; b) general and specific structure; c) hermeneutics of discourse. As an illustration I apply the itinerary to a poetic text. I conclude that the script allows, in the work of interpretation, to establish the distance from belonging and to overcome the intention of what the author intended to say. (shrink)

O artigo examina as contribuições do pensamento social de Maurice Blondel para a promoção de uma paz duradoura entre as nações. A partir da crítica blondeliana dos totalitarismos e dos regimes liberais, elencamos certas características da ação humana histórica e concreta, individual e social, que fundamentam uma concepção social e política favorável à pluralidade das culturas e à colaboração entre os povos. Como critério crítico e forma normal de promover a busca imanente do bem, da verdade e da justiça, defende-se (...) a transcendência real do espírito humano. Finalmente, elencamse alguns princípios normativos que deveriam compor toda formação e educação pessoal e social apta a promover a paz e o sentimento de humanidade.This article examines the contributions of the social thought of Maurice Blondel for the promotion of a lasting peace among nations. Drawing from the Blondelian criticism of totalitarian systems and of liberal regimes, we list certain characteristics of historic and concrete human action, both individual and social. Those features frame a social and political view which is favorable to the plurality of cultures and fosters collaboration among peoples. The article argues that the real transcendence of the human spirit is the critical criterion and the normal path to promote the immanent search of good, truth and justice. Finally, we list some normative principles that should inform all formation programs, and personal and social education as well, in order for them to be apt to promote peace and a sense of common humanity.

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

It is well known that Emmanuel Levinas places the ‘other’ at the heart of his phenomenology, as an agency the relation toward which constitutes subjectivity. As such, the Levinasian other is deprived of violence, and it is identified with the figures of the foreigner, the orphan, and the widow. The only resistance the other could muster against the violence directed at him/ her, argues Levinas, is what he terms as the resistance of lack of resistance. This article aims at questioning (...) this premise. Is the other indeed deprived of any violence? The readings of Derrida, Sartre, Foucault, Agamben, Freud, and Lacan can prove otherwise: either the other is equipped with contingent violence, in accordance with its intentions, as Derrida argues; or it is equipped with a priori violence, administered through the gaze, as Sartre shows. The violence of the other is linked to the violence of identity, as that which alienates the self from itself by depriving it of its fluctuating heterogeneity, whatever name it assumes. (shrink)

However broad or vague the notion of connexivity may be, it seems to be similar to the notion of relevance even when relevance and connexive logics have been shown to be incompatible to one another. Relevance logics can be examined by suggesting syntactic relevance principles and inspecting if the theorems of a logic abide to them. In this paper we want to suggest that a similar strategy can be employed with connexive logics. To do so, we will suggest some properties (...) that seem to be hinted at in Nelson’s work. Following this strategy will ideally shed some light over the notion of content and will also help make a clear comparison between relevance and connexive logics. (shrink)

Despite the application of 2.5 million tons ofpesticides worldwide, more than 40% of all potentialfood production is lost to insect, weed, and plantpathogen pests prior to harvest. After harvest, anadditional 20% of food is lost to another group ofpests. The use of pesticides for pest control resultsin an estimated 26 million human poisonings, with220,000 fatalities, annually worldwide. In the UnitedStates, the environmental and public health costs forthe recommended use of pesticides total approximately$9 billion/yr. Thus, there is a need for alternativenon-chemical (...) pest controls, and genetic engineering(biotechnology) might help with this need. Diseaseand insect pest resistance to various pests has beenslowly bred into crops for the past 12,000 years;current techniques in biotechnology now offeropportunities to further and more rapidly improve thenon-chemical control of disease and insect pests ofcrops. However, relying on a single factor, like theBacillus thuringiensis toxin that has beeninserted into corn and a few other crops for insectcontrol, leads to various environmental problems,including insect resistance and, in some cases, athreat to beneficial biological control insects andendangered insect species. A major environmental andeconomic cost associated with genetic engineeringapplications in agriculture relates to the use ofherbicide resistant crops (HRC). In general, HRCtechnology results in increased herbicide use but noincrease in crop yields. The heavy use of herbicidesin HRC technology pollutes the environment and canlead to weed control costs for farmers that may be2-fold greater than standard weed control costs. Therefore, pest control with both pesticides andbiotechnology can be improved for effective, safe,economical pest control. (shrink)

Much has been said about intuitionistic and classical logical systems since Gentzen’s seminal work. Recently, Prawitz and others have been discussing how to put together Gentzen’s systems for classical and intuitionistic logic in a single unified system. We call Prawitz’ proposal the Ecumenical System, following the terminology introduced by Pereira and Rodriguez. In this work we present an Ecumenical sequent calculus, as opposed to the original natural deduction version, and state some proof theoretical properties of the system. We reason that (...) sequent calculi are more amenable to extensive investigation using the tools of proof theory, such as cut-elimination and rule invertibility, hence allowing a full analysis of the notion of Ecumenical entailment. We then present some extensions of the Ecumenical sequent system and show that interesting systems arise when restricting such calculi to specific fragments. This approach of a unified system enabling both classical and intuitionistic features sheds some light not only on the logics themselves, but also on their semantical interpretations as well as on the proof theoretical properties that can arise from combining logical systems.

Both Carnap and Quine made significant contributions to the philosophy of mathematics despite their diversedviews. Carnap endorsed the dichotomy between analytic and synthetic knowledge and classified certainmathematical questions as internal questions appealing to logic and convention. On the contrary, Quine wasopposed to the analytic-synthetic distinction and promoted a holistic view of scientific inquiry. The purpose of thispaper is to argue that in light of the recent advancement of experimental mathematics such as Monte Carlosimulations, limiting mathematical inquiry to the domain of (...) logic is unjustified. Robustness studies implemented inMonte Carlo Studies demonstrate that mathematics is on par with other experimental-based sciences. (shrink)

O que se buscará com o seguinte artigo é recriar, e analisar, o trajeto filosófico que tem sua origem no conceito kantiano de Aufklärung, e cuja evolução nos levará até o conceito foucaultiano de “ontologia crítica”. Em 1784, Kant diria num artigo do jornal alemão Berlinische Monatsschrift que a Aufklärung seria uma saída da minoridade do homem, e por minoridade podemos entender o fato do homem não ser capaz de fazer uso do seu próprio entendimento, ficando assim dependente da razão (...) de tutores. A partir disto, Foucault, em 1984, diria que a originalidade desta resposta de Kant está exatamente em não propor um método ou uma doutrina, mas antes, em incitar uma ação: propriamente a ação de saída [Ausgang]. Assim, Foucault nos apresentaria sua “ontologia crítica”; que diferentemente da ontologia tradicional que busca capturar os acontecimentos numa doutrina, o papel da ontologia foucaultiana seria exatamente o de tornar o sujeito incapturável por qualquer doutrina que apreende os acontecimentos num SER exclusivo. O que Foucault faria, desta forma, seria levar o conceito de Kant mais além, propondo mesmo um trabalho infinito, não apenas mais para sair, mas para igualmente permanecer fora do estado de minoridade.

Psychogenic non epileptic seizures (PNES) are clinical events of psychological nature. Video-electroencephalography monitoring (V-EEGM) is a valuable method for the diagnosis of PNES and may be combined with provocative tests to induce seizures. The use of placebo in provocative tests for the diagnosis of PNES is controversial because of associated deception, and contrasts with the use of truly decreasing epileptogenic threshold techniques such as hyperventilation and photo stimulation. We present a clinical case of a pregnant woman with a past history (...) of refractory epilepsy, admitted in the obstetric department due to unremitting seizures. In this clinical context, non-deceiving provocative tests such as hyperventilation and photo stimulation could be potentially harmful, nevertheless, the use of intravenous saline injection presented as a safer alternative to diagnose PNES and hence obviate an urgent caesarean. This case illustrates a disproportionate risk of causing harm when telling the truth, in comparison with the benefit of avoiding such risk, although deceiving the patient. This is a clinical example of how considerations concerning the use of placebo must be evaluated in an individual basis. (shrink)

O DIREITO ENTRE O ESTADO E O ESTADO DE DIREITO: REVISITANDO A TEORIA DO DIREITO E DO ESTADO DE LEÓN DUGUIT.

A juventude evangélica brasileira se viu, durante os anos 1970, bombardeada por uma carga considerável de versões fundamentalistas da escatologia e, com isso, essa questão veio a ocupar um lugar secundário dentre os temas teológicos dos evangélicos brasileiros. A introdução de uma perspectiva não disjuntada da escatologia, como a do teólogo George Eldon Ladd, foi o que possibilitou a difusão da Teologia da Missão Integral, indicando o quanto a missiologia é inseparável de escatologia. Posteriormente, as versões fundamentalistas mantiveram um espaço (...) menos popular, mas constante, nas igrejas. O quadro foi acrescido da Teologia da Prosperidade, que trouxe a noção de uma escatologia individualista. Portanto, de um lado temos uma escatologia construída numa perspectiva não disjuntada do tempo, e do outro uma visão escatológica fundamentalista e privatizada. O enfrentamento dessas duas tendências expressa a contínua tensão entre o dualismo e a integralidade na história do cristianismo. No Novo Testamento, as imagens da barraca (João 1.14, Atos 18.1-3) e da cortina (Mateus 27.45-52) servem para compreender a dinâmica do “habitar entre” em contraste com a do fechamento do sagrado no espaço do haram . Esses dois modos de habitar, na linha de pensamento do filósofo Peter Sloterdijk, ilustram essas duas tendências. Palavras-chave: Juventude Evangélica. Escatologia. Fundamentalismo. Teologia da Missão Integral.: Brazilian evangelical youth was, in 1970’s overflowed with a big variety of fundamentalistic versions of eschatology. That’s why this theme came to occupy a secondary place between the others theological themes in Brazilian evangelical Theology. The introduction of a non disjointed version of eschatology, as Georg Eldon Ladd’s, for instance, make possible the diffusion of IMT (Integral Mission Theology), demonstrating how Missiology is inseparable from eschatology. After that, fundamentalistic versions lost their popularity, but kept their presence in churches. Prosperity Theology brought a complete individualistic notion of eschatology. So, we have in one side a eschatology built on a non disjointed notion of time and reality, and in another, the fundamentalistic and privatized version. The clash of these two tendencies expresses the continuous tension between dualism and integrality in the History of Christianity. In the New Testament, the images of the tent (John 1.14, Acts 18.1-3) and of the curtain (Mathews 27.45-52) are useful to understand the logic of “live-between” in opposition with the closeness of the sacred in the haram . These two ways of dwell, following the thought of the philosopher Peter Sloterdijk, exemplify those two tendencies. Key words: Evangelical Youth. Eschatology. Fundamentalism. Integral Mission Theology. (shrink)

O artigo examina a questão do ideológico nos discurssos de Locke e Rousseau, e conclui que os critérios de leitura de um e de outro,originários da própria natureza destes,não devem ser unívocos porque as respectivas subjetividades são marcadas por práticas historicamente diferentes.

In 2015 Dag Prawitz proposed a natural deduction ecumenical system, where classical logic and intuitionistic logic are codified in the same system. In his ecumenical system, Prawitz recovers the harmony of rules, but the rules for the classical operators do not satisfy separability. In fact, the classical rules are not pure, in the sense that negation is used in the definition of the introduction and elimination rules for the classical operators. In this work we propose an ecumenical system adapting, to (...) the natural deduction framework, Girard’s mechanism of stoup. This allows for the definition of a pure harmonic natural deduction system for the propositional fragment of Prawitz’s ecumenical logic. We conclude by presenting an extension proposal to the first-order setting and a different approach to purity based on some ideas proposed by Julien Murzi. (shrink)

Because the agriculture/food sectors appear to be driven by short-term economic and political forces, cheap energy, and agricultural-chemical technologies, waste and environmental/social problems in the agricultural/food sectors are estimated to cost the nation at least $150 billion per year. Most of the waste and environmental/social problems can be eliminated through better resource management policies and the adoption of sustainable agricultural practices.

Ensaio sobre a compreensão do corpo baseada em autores que dialogam com a fenomenologia e a gestalt-terapia. Crítica ao distanciamento entre vida cotidiana, senso comum e ciência baseada no modelo natural. Na concepção fenomenologica o conceito de “mundo da vida” permite diferenciar um corpo vivo, um Leib, de um corpo não vivo Körper. E o corporar é um dos modos de ser do Dasein. Em Gestal-terapia o conceito de todo aplicado a percepção e a vivência do corpo contribui para a (...) compreensão de nós não temos um fígado e um coração, nós somos fígado, coração, cérebro, e assim por diante.

This volume contains the selected discourses of four seventeenth-century philosophers, carefully chosen to illustrate the tenets characteristic of the influential movement known as Cambridge Platonism. Fundamental to their beliefs is the statement most clearly voiced by Benjamin Whichcote, their leader by common consent, that the spiritual is not opposed to the rational, nor Grace to nature. Religion is based on reason, even in the presence of 'mystery'. Free will and Grace are not mutually exclusive. The editor's comprehensive introduction delineates the (...) main principles of the Cambridge Platonists, in the light of their heritage. It compares their attitude to contemporary thought, stressing their mistrust both of institutionalised religion and of the rising tide of materialism. The sermons are reprinted from the original texts and fully annotated with comparisons and references to a wide range of works. The editor also includes a useful list for further reading, biographical notes and a comprehensive index. (shrink)

Estudo qualitativo exploratórios de literatura cientifica sobre ansiedade em estudantes brasileiros, objetivando identificar fatores relacionados ao desenvolvimento da ansiedade patológica. Os textos foram analisados e agrupados de acordo com análise de conteúdo. Entre os resultados encontramos o enfoque relacional que impacta o self e surge no contexto socioeconômico. Destacamos como agentes que contribuem para a ansiedade: exigência de responsabilidade e autonomia; preocupações com o futuro; não ter tempo para o lazer, ausência de familiares; ser mulher e ser homossexual. Concluímos que (...) o modelo de ensino praticado na universidade causa pressão psicológica pela grande diferença da experiência pedagógica no secundário. Completamos que a Universidade requer promover intervenções que visem o desenvolvimento emocional e cognitivo dos estudantes para que desenvolvam seu método de estudar mais eficiente, lidar melhor com suas dificuldades, e gerar estratégias para lidar com elas, além de organizar o planejamento tempo reservando horas para atividades de lazer e de interação social.

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all (...) regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)
