One of the more obscure arguments for Rawls’ difference principle dubbed ‘the Pareto argument for inequality’ has been criticised by G. A. Cohen (1995, 2008) as being inconsistent. In this paper, we examine and clarify the Pareto argument in detail and argue (1) that justification for the Pareto principles derives from rational selfinterest and thus the Pareto principles ought to be understood as conditions of individual rationality, (2) that the Pareto argument is not inconsistent, contra Cohen, and (3) that the (...) kind of bargaining model required to arrive at the particular unequal distribution that the difference principle picks out is a model that is not based on bargaining according to one’s threat advantage.

This paper observes that P. F. Strawson’s distinction between descriptive and revisionary metaphysics is a baffling one from the perspective of traditional metaphysics. If one thinks of metaphysics as the study of the fundamental nature of reality, it is bewildering to divide up metaphysics in this way. The paper then tries to show how the distinction is no longer bewildering if we deny that such study is possible.

This inquiry is addressed to two questions: (1) what if any logical relations might exist between the concepts of desire and action (as they and the distinctions to which they commit us are ensconced in ordinary parlance), and (2) what if any causal or significant non-causal (i.e., material) relations might ever exist between instances of desire and action? -/- It is held that any credible move to deal with such questions must initially, and at some length, specify the employment conditions (...) for the terms 'want' and 'desire'. This is accomplished in the first two chapters wherein a set of premises is generated for the argument of the inquiry which is presented in full and concluded in the third and final chapter. Premises generated devolve from treatment of the following major topics: (a) the grammar of 'want' and 'desire', (b) the ontological status of wants, (c) first-person and third-person want ascriptions, (d) the sorts of things which may be desired (desiderabilia), (e) wants and lacks, (f) wants and wishes, (g) the 'conflicts' of desires and reason and desire, (h) four major candidates for logical relations between wants and acts, (i) the issue of causation, and (j) the placement of Desire in an adequate ontology of persons. -/- It is argued that every major candidate for a logical relation between wants and acts (or our warrant for believing that such a connection exists) breaks down upon analysis; that little warrant exists for construing wants as causes of acts; that wants and acts are related in significant non-logical and non-causal (i.e., material) respects; and that any fully adequate theory of human action must undertake ontology, placing the category of Desire squarely in the foreground. This project represents neither a general theory of desire nor a general theory of human action. It is rather conceived as a propaedeutic to any such inquiry. It is essentially revisionist in intent, setting out on the one hand to challenge existing claims about wants and acts and, on the other hand, proposing a more satisfactory approach to the issue. In no sense is it suggested that recent Anglo-American contributions are without merit. It is rather argued that they are often inadequate contributions vis-a-vis the larger requirements for an adequate theory of human action. (shrink)

This paper evaluates the following argument, suggested in the writings of Donald Davidson: if there is such a thing as the given, then there can be alternative conceptual schemes; there cannot be alternative conceptual schemes; therefore there is no such thing as the given.

There is an intuition that the past does not ever change. In their paper ‘The puzzle of the changing past,’ Luca Barlassina and Fabio Del Prete argue that in 2012 the past changed. I show that we are not in a position to accept their argument.

A. W. F. Edwards famously named “Lewontin’s fallacy” after Richard Lewontin, the geneticist who showed that most human genetic diversity can be found within any given racialized group. “Lewontin’s fallacy” is the assumption that uncorrelated genetic data would be sufficient to classify genotypes into conventional “racial” groups. In this chapter, I argue that Lewontin does not commit the fallacy named after him, and that it is not a genuine fallacy. Furthermore, I argue that when Edwards assumes that stable (...) classification is all it takes to vindicate racial naturalism, he commits a fallacy of his own: Edwards’ fallacy. The ability to create a classificatory system, and then reliably sort things within that system, is not enough to make that system scientifically respectable. I show that Edwards’ fallacy is rife in debates about the existence of human biological races. (shrink)

The impact of crude oil on the permeability of the soil in a non oil producing community in Enugu State was investigated using disturbed A 6 CL soil sample collected from Ibagwa Nike area of the state. The sample was divided into five 5 portions and each of the four 4 portions was dosed with Bonny light crude oil at 2 , 4 , 6 and 8 by weight of the samples. The physical properties of the uncontaminated soil were tested (...) and analyses and used as control. The aim of the laboratory investigation was to determine the effects of crude oil on the permeability of the soil. The permeability of the uncontaminated soil was found to be 1.2609x10 7. Permeability tests were also conducted on the contaminated soil samples at the various percentage contaminations. The results showed that at 2 crude oil contamination the permeability was 9.6403x10 9, a drastic reduction. The other results were 6.9600x10 6, 2.2621x10 8 and 9.1286x10 8 at 4 , 6 , and 8 contamination levels, respectively. The ranking after contamination is seen to drop within the range of 10 8 and 10 9 showing a change in the permeability due to oil content. This observed reduction in permeability alters the natural groundwater recharge which can be remedied by enhanced bioremediation through aeration of the soil. Iloeje A. F. | Aniago V.

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

This is a sketch of the basis and role of consciousness and the minimally required elements and constraints of any setting that may produce consciousness. It proposes that consciousness (as we know it) is a biologically-mediated product of evolved recursive and hierarchically nested representational systems that obey information theoretic principles and Bayesian (probabilistic) feedback and feedforward predictive modeling processes.

This is a conjecture about the conditions and operating structures that are required for the phenomenality of certain mental states. Specifically, full-blown phenomenality is assumed, as contrasted with constrained examples of phenomenal experience such as sensations of color and pain. Propositional attitudes and content, while not phenomenal per se, are standardly concurrent and may condition phenomenal states (e.g., when tied to false beliefs). It is conjectured that full phenomenality natively arises in coherent processes of situated sensory synthesis and representation (with (...) conceptual content) that are looped, mereologically whole and multi-dimensional. And that phenomenal states are typically phase-states within a parameterized conjoint structure of world and experiencer processes that are causally modulated across Markov blankets (which are conditionally independent and may be nested: cf. M. Kirchoff, et. al., 2017, 2018; and T. Burge, 2010, re: anti-individualism). Though they may, it is not accepted that phenomenally conscious states must be targets of higher-order representations (cf. A. Byrne, 2004). (shrink)

An interview with Ed Casey where we discuss the intersections of his philosophical work with current political issues, including the Israel-Palestine conflict.

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined (...) with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

Timelines is an inquiry into the nature of time, both as an apparent feature of the external physical world and as a fundamental feature of our experience of ourselves in the world. The principal argument of Timelines is that our coventional ideas about time are largely mistaken and that what we think of as independent physical time is actually our calibration of a certain relation between events. Namely, the relation between time-keeping events and the causal sequential differences of physical processes (...) which are real and independent of us. (shrink)

PREMISSA No século XIX, ocorreram transformações impulsionadas pela emergência de novas fontes energéticas (água e petróleo), por novos ramos industriais e pela alteração profunda nos processos produtivos, com a introdução de novas máquinas e equipamentos. Depois de 300 anos de exploração por parte das nações europeias, iniciou -se, principalmente nas colônias latino-americanas, um processo intenso de lutas pela independência. É no século XIX, já com a consolidação do sistema capitalista na Europa, que se encontra a herança intelectual mais próxima da (...) qual surgirá a Sociologia como ciência particular. No início desse século, as ideias do Conde de Saint-Simon (1760-1825), de Georg Wilhelm Friedrich Hegel (1770-1831), de David Ricardo (1772-1823) e de Charles Darwin (1809-1882), entre outros, foram o elo para que Alexis de Tocqueville (1805-1859), Auguste Comte (1798-1857), Karl Marx (1818 -1883) e Herbert Spencer (1820-1903), entre outros, desenvolvessem reflexões sobre a sociedade de seu tempo. Auguste Comte e Karl Marx foram os pensadores que lançaram as bases do pensamento sociológico e de duas grandes tradições – a positivista e a socialista – que muito influenciaram o desenvolvimento da Sociologia no Brasil. 1 AUGUSTE COMTE E A TRADIÇÃO POSITIVISTA Isidore Auguste Marie François Xavier Comte nasceu em Montpellier, na França, em 19 de janeiro de 1798. Com 16 anos de idade, ingressou na Escola Politécnica de Paris, fato que teria significativa influência na orientação posterior de seu pensamento. De 1817 a 1824, foi secretário do Conde de Saint-Simon. Comte declarou que, com Saint -Simon, aprendeu muitas coisas que jamais encontraria nos livros e que, no pouco tempo em que conviveu com o conde, fez mais progressos do que faria em muitos anos, se estivesse sozinho. Toda a obra de Comte está permeada pelos acontecimentos que ocorreram após a Revolução Francesa de 1789. Ele defendeu parte dos princípios revolucionários e criticou a restauração da monarquia, preocupando-se fundamentalmente em reorganizar a sociedade, que, no seu entender, estava em ebulição e mergulhada no caos. Para Comte, a desordem e a anarquia imperavam em virtude da confusão de princípios (metafísicos e teológicos), que não se adequavam à sociedade industrial em expansão. Era, portanto, necessário superar esse estado de coisas, usando a razão como fundamento da nova sociedade. Propôs, então, a mudança da sociedade por meio da reforma intelectual plena das pessoas. De acordo com o pensador, com a modificação do pensamento humano, por meio do método científico, que ele chamava de “filosofia positiva”, haveria uma reforma das instituições. Com a proposta do estudo da sociedade por meio da análise de seus processos e estruturas, e da reforma prática das instituições, Comte criou uma nova ciência, à qual deu o nome de “física social”, passando a chamá-la posteriormente de Sociologia. A Sociologia representava, para Comte, o coroamento da evolução do conhecimento, mediante o emprego de métodos utilizados por outras ciências, que buscavam conhecer os fenômenos constantes e repetitivos da natureza: a observação, a experimentação, a comparação e a classificação. De acordo com esse pensador, a Sociologia, como as ciências naturais, deve sempre procurar a reconciliação entre os aspectos estáticos e os dinâmicos do mundo natural ou, no caso da sociedade humana, entre a ordem e o progresso. O lema da “filosofia positiva” proposta por Comte era “conhecer para prever, prever para prover”, ou seja, o conhecimento é necessário para fazer previsões e também para solucionar possíveis problemas. A influência de Comte no desenvolvimento da Sociologia foi marcante, sobretudo, na escola francesa, evidenciando-se em Émile Durkheim e seus contemporâneos e seguidores. Seu pensamento esteve presente em muitas das tentativas de criar tipologias para explicar a sociedade. Suas principais obras são: Curso de filosofia positiva (1830-1842), Discurso sobre o espírito positivo (1848), Catecismo positivista (1852) e Sistema de política positiva (1854). Para concluirmos, Comte explanava que para a superação da anarquia reinante na nova sociedade industrial, a filosofia positivista defendia a subordinação do progresso à ordem. O mesmo era contra o retorno de Luís XVIII ao trono: em sua concepção, a sociedade industrial que emergia requeria um governo fundado na razão. 2 A TRADIÇÃO SOCIALISTA: KARL MARX E FRIEDRICH ENGELS Karl Heinrich Marx nasceu em Tréveris, na antiga Prússia, hoje Alemanha, em 1818 e, em 1830, ingressou no Liceu Friedrich Wilhelm, nessa mesma cidade. Anos depois, foi cursar Direito na Universidade de Bonn, transferindo-se para Berlim em seguida. Pouco a pouco, entretanto, seus interesses migraram para a Filosofia, área na qual defendeu, em 1841, a tese de doutorado A diferença da filosofia da natureza em Demócrito e Epicuro. Sua vida universitária foi marcada pelo debate político e intelectual influenciado pelo pensamento de Ludwig Feuerbach (1804-1872) e, principalmente, pelo de Georg Wilhelm Friedrich Hegel (1770- 1831). Friedrich Engels (1820-1895) nasceu em Barmen (Renânia), na antiga Prússia, hoje Alemanha, filho mais velho de um rico industrial do ramo têxtil. Terminou sua formação secundária em 1837 e a partir de então sua formação intelectual foi por conta própria (autodidata), com alguns cursos universitários esparsos e de curta duração. Desde cedo começou a trabalhar nas empresas de seu pai e foi nessa condição que se deslocou para Bremen por três anos e depois foi enviado pelos pais a Manchester, na Inglaterra, onde trabalhou nas fábricas da família. Engels ficou impressionado com a miséria na qual viviam os trabalhadores das fábricas inglesas. Os dois, Marx e Engels, se encontraram em 1842, quando Marx passou a escrever para A Gazeta Renana, jornal da província de Colônia, do qual Engels era colaborador e mais tarde editor-chefe. O jornal, que criticava o poder prussiano, foi fechado em 1843, e Marx se viu desempregado. Ao perder o emprego, mudou-se para Paris, na França. Ali escreveu, em 1844, os Manuscritos econômico-filosóficos (só publicados em 1932) e, junto com F. Engels, o livro A sagrada família. Por sua vez, F. Engels, em 1844, decidiu voltar para a Alemanha, onde publicou, em 1845, A situação da classe trabalhadora na Inglaterra. Entre 1845 e 1847, Marx exilou-se em Bruxelas, na Bélgica, onde escreveu A ideologia alemã (em parceria com Friedrich Engels) e Miséria da filosofia (1847), obra na qual criticou o filósofo Pierre-Joseph Proudhon (1809-1865). Em 1848, ainda na Bélgica, a parceria com Engels se solidificou ao escreverem juntos o livreto O Manifesto Comunista. Em 1848, Marx foi expulso da Bélgica e retornou a Colônia, na Alemanha (Prússia), sempre pensando na possibilidade de uma mudança estrutural em sua terra natal. Isso, entretanto, não aconteceu e Marx foi expulso da Alemanha em 1849, ano em que migrou para Londres, na Inglaterra, onde permaneceu até o fim da vida. Lá escreveu O 18 Brumário de Luís Bonaparte (1852), sua mais importante obra de reflexão sobre a vida política europeia do século XIX, desenvolveu pesquisas e concluiu seu maior trabalho: O capital: crítica da economia política. O primeiro volume dessa obra foi publicado em 1867; os outros três, em 1885, 1894 e 1905, após a morte de Marx, revisados por F. Engels. 2.1 O contexto histórico e a obra de Marx e Engels Para situar a obra de Marx e Engels, é necessário conhecer um pouco do que acontecia em meados do século XIX. Com as transformações que ocorriam no mundo ocidental, principalmente na esfera da produção industrial, houve um crescimento expressivo no número de trabalhadores industriais urbanos, com uma consequência evidente: precariedade da vida dos operários nas cidades. As condições de trabalho no interior das fábricas eram péssimas. Os empregados eram superexplorados, alimentavam-se mal e trabalhavam em ambientes insalubres. Para enfrentar essa situação e tentar modificá-la, os trabalhadores passaram a se organizar em associações e sindicatos e a promover movimentos de reivindicação. Desenvolveu-se, então, uma discussão das condições sociais, políticas e econômicas para se definirem as possibilidades de intervenção nessa realidade. Desde o início do século XIX, muitos pensadores discutiram essas questões, nas perspectivas socialista e anarquista. Na Inglaterra podem ser citados, entre outros: William Godwin (1756-1836), Thomas Spence (1750-1814), Thomas Paine (1737-1809), Robert Owen (1771-1858) e Thomas Hodgkin (1787-1866). Na França, destacaram-se Étienne Cabet (1788- 1856), Flora Tristan (1803-1844), Charles Fourier (1772-1837) e Pierre-Joseph Proudhon (1809-1865). Marx e Engels levaram em conta esses pensadores, debatendo com alguns contemporâneos e criticando-os. Além disso, incorporaram a tradição da economia clássica inglesa, presente principalmente nas obras de Adam Smith e de David Ricardo. Pode-se dizer, portanto, que Marx e Engels desenvolveram seu trabalho com base na análise crítica da economia política inglesa, do socialismo utópico francês e da filosofia alemã. Esses dois autores não buscavam definir uma ciência específica para estudar a sociedade (como a Sociologia, para Auguste Comte) ou situar seu trabalho em um campo científico particular. Em alguns escritos, Marx afirmou que a História seria a ciência que mais se aproximava de suas preocupações, por abarcar as múltiplas dimensões da sociedade, a qual deveria ser analisada na totalidade, não havendo uma separação rígida entre os aspectos sociais, econômicos, políticos, ideológicos, religiosos, culturais etc. O objetivo de Marx e Engels era estudar criticamente a sociedade capitalista com base em seus princípios constitutivos e em seu desenvolvimento, visando dotar a classe trabalhadora de uma análise política da sociedade de seu tempo. Assim, a tradição socialista nascida da luta dos trabalhadores, muitos anos antes e em situações diferentes, tem como expressão intelectual o pensamento de Karl Marx e Friedrich Engels. Para entender as concepções fundamentais de Marx e Engels é necessário fazer a conexão entre as lutas da classe trabalhadora, suas aspirações e as ideias revolucionárias que estavam presentes no século XIX na Europa. Para eles, o conhecimento científico da realidade só tem sentido quando visa à transformação dessa mesma realidade. A separação entre teoria e prática não é discutida, pois a “verdade histórica” não é algo abstrato e que se define teoricamente; sua verificação está na prática. Apesar de haver algumas diferenças em seus escritos, os elementos essenciais do pensamento de Marx e Engels podem ser assim sintetizados: • historicidade das ações humanas – crítica ao idealismo alemão; • divisão social do trabalho e o surgimento das classes sociais – a luta de classes; • o fetichismo da mercadoria e o processo de alienação; • crítica à economia política e ao capitalismo; • transformação social e revolução; • utopia – sociedade comunista. A obra desses dois autores é muito vasta e não ficou vinculada estritamente aos movimentos sociais dos trabalhadores. Pouco a pouco foi introduzida nas universidades como parte do estudo em diferentes áreas do conhecimento. Estudiosos de Filosofia, Sociologia, Ciência Política, Economia, História e Geografia, entre outras áreas, foram influenciados por ela. Na Sociologia, como afirma Irving M. Zeitlin, no livro Ideología y teoría sociológica, tanto Max Weber quanto Émile Durkheim fizeram, em suas obras, um debate com as ideias de Karl Marx. Pelas análises da sociedade capitalista de seu tempo e a repercussão que tiveram em todo o mundo, principalmente no século XX, nos movimentos sociais e nas universidades, Marx e Engels são considerados autores clássicos da Sociologia. No campo dessa disciplina, porém, o pensamento deles ficou um pouco restrito, pois perdeu aquela relação entre teoria e prática (práxis), ou seja, entre a análise crítica e a prática revolucionária. Essa relação esteve presente, por exemplo, na vida e na obra dos russos Vladimir Ilitch Ulianov, conhecido como Lênin (1870-1924), e Leon D. Bronstein, conhecido como Trotsky (1879-1940), da alemã Rosa Luxemburgo (1871-1919) e do italiano Antonio Gramsci (1891- 1937), que tiveram significativa influência no movimento operário do século XX. Com base no trabalho de Marx e Engels, muitos autores desenvolveram estudos acadêmicos em vários campos do conhecimento. Podemos citar, por exemplo, Georg Lukács (1885-1971), Theodor Adorno (1903-1969), Walter Benjamin (1892-1940), Henri Lefebvre (1901-1991), Lucien Goldmanm (1913 -1970), Louis Althusser (1918 -1990), Nikos Poulantzas (1936-1979), Edward P. Thompson (1924-1993) e Eric Hobsbawm (1917 -2012). O pensamento de Marx e Engels continua, assim, presente em todo o mundo, com múltiplas tendências e variações, sempre gerando controvérsias.

Background: Obstetrics and gynaecology are many and common, where a woman suffers from problems related to pregnancy or her reproductive organs. Any part of her body may be affected due to some symptoms that are completely related to the reproductive organs when she is in a critical period for her, whether in her menstrual cycle, pregnancy, or disease conditions. The bulk of cases of diseases related to women and childbirth are dealt with great care and special care, as all diseases (...) related to women are considered very sensitive diseases due to the presence of the disease in sensitive and not simple places. A gynaecologist is a specialist in all diseases and problems related to the female sexual organs. They perform regular preventive medical exams, such as cervical smear tests and breast exams. It also provides consultations for women of all ages about the problems of contraception, infertility and menopause. Objectives: The objective of this expert system is to help and facilitate women in diagnosing diseases related to their obstetrics and gynaecology, a simple expert system has been designed consisting of ten various common diseases that affect women whether During or without pregnancy, Methods: In this system, the system consists of a list of some common symptoms, the correct diagnosis adopted for these diseases, and how to treat diseases in the correct way with the help of a consultant obstetrician and gynaecologist, Dr. Fathi Muhammad Al-Habibi, and these diseases are: uterine cancer, cervical cancer, Infertility, double uterus, ectopic pregnancy, endometrial cancer, female sexual dysfunction, endometriosis, faecal incontinence, female infertility, CLIPS Expert System language was used to design and implement the proposed expert system. Results: The proposed ten obstetrics and gynaecology diagnostic expert system was evaluated by medical students and they were satisfied with its performance. Conclusions: The proposed expert system is very useful for obstetricians and gynaecologists, patients with reproductive system problems, and recent graduates. (shrink)

It is observed that most development modalities employed over the years for achieving community development in Africa have not leaved up to expectation in terms of involving the majority of people in the quest for national transformation and development; rather, these modalities tend to complicate the very problems they are set out to solve. The situation is mostly like this because the adopted development strategies have not taken adequate cognizance the essence of effective communication methods and the importance of people’s (...) perspectives and peculiarities in these processes. Mostly, the so-called outsiders and experts in development matters who are physically and socially separated from the people think for them and about their development. This situation is inimical to genuine and sustainable development. It is important therefore to note that development can only be meaningful and sustainable when it is people generated; involving people’s real needs and their participation in the process of achieving them. It is at this point therefore that community theatre can come handy as it has the potentials to bring people together to discuss issues that disempowered them and participatorily proffer solutions to the negatives. Community theatre can be explored to work with rural and urban people; mostly the rural dwellers who are mostly disempowered. In view of this therefore, this paper posits that community theatre is a method of participatory communication towards achieving social change. (shrink)

Simone de Beauvoir and Jean-Paul Sartre struggled for the whole of their philosophical careers against one of modern Western philosophy's most pervasive concepts, the Cartesian notion of self. A notion of self is always a complex of ideas; in the case of Beauvoir and Sartre it includes the ideas of embodiment, temporality, the Other, and intersubjectivity. This essay will show the considerable part that gender, especially Beauvoir's position as a woman in twentieth-century France, played in the development, presentation and reception (...) of the couple's alternative formulation.

En este artículo argumentamos que la naturaleza pública o privada de la educación tiene una incidencia directa en las instituciones que conforman la realidad social. Para sustentar lo anterior, en primer lugar discutimos cómo, según Searle, habitamos un mundo de instituciones gobernadas por reglas y poderes deónticos, ontológicamente irreductibles. Luego, postulamos que la intencionalidad colectiva requiere de la confianza para mantenerse, y esta aumenta cuando gobiernan reglas y poderes deónticos en circunstancias normales. Finalmente, planteamos que la educación pública es una (...) institución que, a diferencia de la privada, privilegia el espacio de lo común. Sócrates es un ejemplo de esto, al proponer una filosofía que no solo busca la verdad, sino que además privilegia el reconocimiento de la ley por sobre la satisfacción inmediata de deseos e inclinaciones personales. De todo esto se explica el círculo virtuoso: la educación pública, al ser inclusiva y beneficiar a todos, potencia las instituciones sociales que tutelan ese interés y, dentro de ellas, el servicio público.

La psicología contemporánea parece caracterizarse desde sus propios orígenes por la multiplicidad de sus contenidos, además de por su casi infinita fragmentación en corrientes encontradas. Esto crea importantes dificultades, no sólo a quienes quieran tener una primera aproximación, sino también a los especialistas, que muchas veces no llegan a una opinión suficientemente clara sobre la naturaleza epistemológica de la psicología, ni sobre su unidad disciplinar. Esta obra, sin descuidar el problema global, se centra en un aspecto particular: el que presenta (...) la praxis de la psicología, en particular la psicoterapia y sus fundamentos teóricos. Se pone especial interés en una visión crítica del psicoanálisis, punto de referencia inevitable (positivo o negativo) para la mayoría de las corrientes de psicoterapia. Pero este intento de esclarecimiento epistemológico y práctico se lleva a cabo desde un punto de vista original: a la luz del pensamiento de Santo Tomás de Aquino (1225-1274), conocido como uno de los más grandes teólogos y filósofos de la Iglesia Católica. Las calidades del Aquinate como epistemológico son sobradamente conocidas. Menos conocida es su faceta de psicólogo, que esta obra quiere poner de manifiesto con gran detalle para evidenciar la actualidad de las líneas maestras de la psicología de Santo Tomás, como también la posibilidad de practicar hoy la psicología bajo la guía fundamental del Doctor Humanitatis.\n.

This paper distinguishes three concepts of "race": bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards' 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially crucial to the first episode, while normativity is central to the second. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. We conclude by (...) interrogating the relevance of these scientific discussions for political positions and a post-racial future. (shrink)

There are some premise-by-premise reconstructions in political philosophy which are flawed, because they omit at least one premise or misword at least one premise. This paper focuses on a reconstruction by Richard Child. The original argument is by Andrea Sangiovanni and is about whether egalitarian values of distributive justice apply both within a state and globally. Child’s reconstruction has been reproduced in a paper by Ian Davis, who approves of it. But I point out five logical problems with the reconstruction.

Background: There is no doubt that strawberry diseases are one of the most important reasons that led to the destruction of strawberry plants and their crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases after a good step for proper and correct treatment. Determining the treatment with high accuracy depends on the method used in the diagnosis. Correctly, expert systems can greatly help in avoiding damage to these plants. The expert system correctly diagnoses (...) strawberry disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment. Methods: In this paper the design of the proposed Expert System which was produced to help Farmers and students interested in agriculture strawberry in diagnosing many of the strawberry diseases such as: Leaf Spots, Grey Mold, Red Stele/Red Core, Wilt, Powdery Mildew, Alternaria Spot, Black Root Rot, Anthracnose (black spot), and Angular Leaf Spot. The proposed expert system presents an overview about strawberry diseases are given, the cause of diseases are outlined and the treatment of disease whenever possible is given out. CLIPS language was used for designing and implementing the proposed expert system. Results: The proposed strawberry diseases diagnosis expert system was evaluated by Farmers and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for Farmers with strawberry problem and students interested in agriculture strawberry. (shrink)

Environmental philosophy – broadly conceived as using philosophical tools to develop ideas related to environmental issues – is conducted and practised in highly diverse ways in different contexts and traditions in Asia. ‘Asian environmental philosophy’ can be understood to include Asian traditions of thought as well as grassroots perspectives on environmental issues in Asia. Environmental issues have sensitive political facets tied to who has the legitimacy to decide about how natural resources are used. Because of this, the works, practices, and (...) researchers in Asian environmental philosophy are exposed to being (mis)used by diverse stakeholders and actors to support political ends not related to environmental sustainability. Two processes are at play at the nexus of the construction of identities in relation to conceptualisations of nature: eco-orientalism and ecological nationalisms. This paper analyzes and exemplifies these dynamics through a conceptual framework that distinguishes ideological and socio-technical explanations of environmental degradation. Finally, to minimise the risks of political misuse, five pathways are presented to carefully help curate environmental, philosophical statements: contextualise, quantify uncertainty and ‘uniqueness’, downscale, confront claims with local realities and literature, and collaborate with researchers from other disciplines. Conjointly, these pathways aim at favouring intercultural collaboration while valuing diversity, thus supporting the development and exchanges in environmental philosophy in Asia and beyond.

Some formulations of the surprise paradox involve a pair of unnecessary and controversial assumptions. After casting doubt on these assumptions, I propose a solution to the paradox.

This paper responds to an argument against a kind of anthropology. According to the argument, if the aim of anthropology is to describe the different worldviews of different groups, then anthropologists should only refer to material artefacts in order to illustrate a worldview; but the interest of artefacts to anthropology goes beyond mere illustration. This argument has been endorsed by key members of the ontological movement in anthropology, who found at least one of its premises in Marilyn Strathern’s writing.

Abstract: Early detection of breast cancer is vital for improving patient outcomes and reducing mortality rates. Technological advancements have significantly enhanced the accuracy and efficiency of screening methods. This paper explores recent innovations in early detection, focusing on the evolution of digital mammography, the benefits of 3D mammography (tomosynthesis), and the application of advanced imaging techniques such as molecular imaging and MRI. It also examines the role of artificial intelligence (AI) in diagnostic tools, showing how machine learning algorithms are improving (...) imaging analysis and reducing diagnostic errors. Furthermore, the paper discusses advancements in genetic screening, liquid biopsies, and biomarkers, emphasizing their potential in identifying high-risk individuals and supporting personalized treatment plans. The paper provides a forward-looking perspective on the future of breast cancer detection, addressing both the opportunities and challenges associated with the adoption of these cutting-edge technologies to improve patient outcomes.

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

The standard representation theorem for expected utility theory tells us that if a subject’s preferences conform to certain axioms, then she can be represented as maximising her expected utility given a particular set of credences and utilities—and, moreover, that having those credences and utilities is the only way that she could be maximising her expected utility. However, the kinds of agents these theorems seem apt to tell us anything about are highly idealised, being always probabilistically coherent with infinitely precise degrees (...) of belief and full knowledge of all a priori truths. Ordinary subjects do not look very rational when compared to the kinds of agents usually talked about in decision theory. In this paper, I will develop an expected utility representation theorem aimed at the representation of those who are neither probabilistically coherent, logically omniscient, nor expected utility maximisers across the board—that is, agents who are frequently irrational. The agents in question may be deductively fallible, have incoherent credences, limited representational capacities, and fail to maximise expected utility for all but a limited class of gambles.

This essay explores Kant’s concept of absolute space in the Metaphysical Foundations from the perspective of the development of the relationist interpretation of bodily interactions in the center-of-mass reference frame, a strategy that Huygens had originally pioneered and which Mach also endorsed. In contrast to the interpretations of Kant that stress a non-relationist, Newton-inspired orientation in his critical period work, it will be argued that the content and function of Kant’s utilization of this reference frame strategy places him much closer (...) to Huygens’ relationism than the absolute notions of space and motion favored by Newton and Euler.

Imprecise probabilities are often modelled with representors, or sets of probability functions. In the recent literature, two ways of interpreting representors have emerged as especially prominent: vagueness interpretations, according to which each probability function in the set represents how the agent's beliefs would be if any vagueness were precisified away; and comparativist interpretations, according to which the set represents those comparative confidence relations that are common to all probability functions therein. I argue that these interpretations have some important limitations. I (...) also propose an alternative—the functional interpretation—according to which representors are best interpreted by reference to the roles they play in the theories that make use of them.

In this paper, we propose a new concept named the uniform single valued neutrosophic graph. An illustrative example and some properties are examined. Next, we develop an algorithmic approach for computing the complement of the single valued neutrosophic graph. A numerical example is demonstrated for computing the complement of single valued neutrosophic graphs and uniform single valued neutrosophic graph.

Abstract: Colon cancer is a prevalent and life-threatening disease, necessitating accurate and timely diagnosis for effective treatment and improved patient outcomes. This research paper presents the development of a knowledge-based system for diagnosing colon cancer using the CLIPS language. Knowledge-based systems offer the potential to assist healthcare professionals in making informed diagnoses by leveraging expert knowledge and reasoning mechanisms. The methodology involves acquiring and structuring medical knowledge specific to colon cancer, followed by the implementation of a knowledge- based system using (...) CLIPS. The system's design integrates relevant medical databases and employs advanced reasoning mechanisms to facilitate accurate diagnosis. Evaluation results demonstrate the system's effectiveness, with high accuracy and sensitivity rates compared to existing methods. The findings highlight the potential of knowledge-based systems in improving clinical practice and patient care. The research contributes to the growing field of medical informatics by demonstrating the feasibility and effectiveness of CLIPS-based knowledge systems for colon cancer diagnosis. Future research can focus on enhancing system performance and expanding its scope to encompass other types of cancer diagnoses. (shrink)

This article argues that the hypothetical 'I Can' position of Sir David Ross is incompatible with his determinism.

This study investigated the experiences of Physical Science teachers who were not specialized in their field. Twelve out-of-field Physical Science teachers, selected via purposive sampling from the Schools Division of Baybay City, participated in the transcendental phenomenological study. For data collection and subsequent thematic analysis using Colaizzi's seven steps, in-depth semi-structured interviews were utilized. Five metaphors describe the study's findings in the form of emergent themes. The first theme is the Chameleon teacher described as an adaptable teacher, analogous to a (...) chameleon that alters its coloration to blend into its surroundings. Developing a resilient mindset is the second aspect, symbolized by the Phoenix Within, which signifies the capacity to triumph over challenges. Thirdly, the Symphony of Knowledge symbolizes teachers' and learners' synergistic partnership and active participation throughout the educational journey. The fourth theme, the Gardener of Knowledge, compares an educator to a conscientious gardener who nurtures their development and that of their students. Crossing Unfamiliar Territory is another theme that examines Physical Science teachers' difficulties when instructing outside their field. As a result, the experiences of these teachers mitigate the issue at hand, thus positively impacting the student's academic development. Sustaining resilience in the face of adversity was inexplicably enhanced through implementing fostering strategies and cultivating a positive mindset. Similar to the adverse encounters, they must confront the obstacles posed by their lack of pedagogical expertise, content knowledge, and struggles. The favorable and unfavorable experiences of physical science teachers who did not specialize in their field provided them professional development opportunities. They underscored the value of maintaining a positive outlook. (shrink)

One response to the problem of logical omniscience in standard possible worlds models of belief is to extend the space of worlds so as to include impossible worlds. It is natural to think that essentially the same strategy can be applied to probabilistic models of partial belief, for which parallel problems also arise. In this paper, I note a difficulty with the inclusion of impossible worlds into probabilistic models. Under weak assumptions about the space of worlds, most of the propositions (...) which can be constructed from possible and impossible worlds are in an important sense inexpressible; leaving the probabilistic model committed to saying that agents in general have at least as many attitudes towards inexpressible propositions as they do towards expressible propositions. If it is reasonable to think that our attitudes are generally expressible, then a model with such commitments looks problematic. (shrink)

Sorensen (1992) has provided two modal-logical schemas to reconstruct the logical structure of two types of destructive thought experiments: the Necessity Refuter and the Possibility Refuter. The schemas consist of five propositions which Sorensen claims but does not prove to be inconsistent.We show that the five propositions, as presented by Sorensen, are not inconsistent, but by adding a premise (and a logical truth), we prove that the resulting sextet of premises is inconsistent. Häggqvist (2009) has provided a different modal-logical schema (...) (Counterfactual Refuter), which is equivalent to four premises, again claimed to be inconsistent. We show that this schema also is not inconsistent, for similar reasons. Again, we add another premise to achieve inconsistency. The conclusion is that all three modal-logical reconstructions of the arguments that accompany thought experiments, two by Sorensen and one by Häggqvist, have now been made rigorously correct. This may inaugurate new avenues to respond to destructive thought experiments. (shrink)

According to comparativism, degrees of belief are reducible to a system of purely ordinal comparisons of relative confidence. (For example, being more confident that P than that Q, or being equally confident that P and that Q.) In this paper, I raise several general challenges for comparativism, relating to (i) its capacity to illuminate apparently meaningful claims regarding intervals and ratios of strengths of belief, (ii) its capacity to draw enough intuitively meaningful and theoretically relevant distinctions between doxastic states, and (...) (iii) its capacity to handle common instances of irrationality. (shrink)

This paper considers five counterexamples to Mary Douglas's definition of dirt, one of which is extracted from a scene from George Eliot's novel Middlemarch and another from Marilyn Strathern's essay on anthropology at home.

I present a paradox concerning a person who desires to fail to achieve the goal that matters most to them. I recently encountered a similar paradox, but radical solipsism is a solution to it. This is not a solution to the paradox that I present.

I present an intractable puzzle for the currently popular view that belief is weak—the view that expressions like ‘S believes p’ ascribe to S a doxastic attitude towards p that is rationally compatible with low credence that p. The puzzle concerns issues that arise on considering beliefs in conditionals. I show that proponents of weak belief either cannot consistently apply their preferred methodology when accommodating beliefs in conditionals, or they must deny that beliefs in conditionals can be used in reasoning.

This study emphasizes the importance of enhancing food safety and hygiene practices among sidewalk vendors to safeguard public health in Balayan Public Market. Employing a mixed-methods approach, with both quantitative and qualitative components, a diverse sample of 55 consumers, 5 sidewalk vendors, and 5 market administrators was selected using a combination of purposive and random sampling techniques under non-probability sampling. Microbial investigations were conducted during both the initial sampling and testing phase (A) and subsequent sampling and testing phase (B) on (...) popular street food items at Lipa Quality Control Inc., including chicken nuggets, chicken nugget sauce (sweet and vinegar), Isaw, Isaw sauce, Proben, Proben sauce, Calamares, Calamares Vinegar Sauce, Kwek- Kwek, and Kwek-Kwek sauce. The findings reveal that “Isaw and Chicken Nuggets Sauce (Sweet)” had a result of “Too Numerous To Count (TNTC),” indicating an extraordinarily high bacteria count. This underscores the imperative need to raise awareness and provide targeted guidance to sidewalk vendors regarding essential food handling, storage, and sanitation practices. Therefore, a sanitary action plan is developed to promote community engagement, educational initiatives, and regulatory support, enhancing food safety practices among sidewalk vendors and ensuring a safer and healthier food environment.

Today's conflicts between religions are grounded largely in historical injustices and grievances but partly in serious conceptual disagreements. This essay agrees with Miroslav Volf that a nontritheistic Christian account of the Trinity is highly desirable. Three traditional models of the Trinity are examined. In their pure, unmixed form, two of them should logically be acceptable to Jews, Muslims, and strict monotheists who regard Christianity as inherently tritheistic, despite lip service to one God. In the social model, three distinct self-aware subjects (...) are unified by being in perfect harmony with each other. Despite Volf's best defense of this, to conceive of three gods, this is how one would go about it. In the psychological model, one divine subject has three psychological capacities—memory, understanding, and will. In the functional model, one subject relates to the world in three different ways—as creator, redeemer, and companion. These two are genuinely monotheistic. Finally, a monotheistic account of the unity of Jesus with God is proposed for consideration. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas. Os humanos evoluíram em estreito contato com a natureza, sendo o leite a primeira fonte de alimento desta espécie ao nascer. Durante milhares de anos, o leite rico em nutrientes, como fonte de alimento, era unicamente materno e só veio a ser consumido pelo homem após idade de amamentação com a domesticação dos animais, primeiramente às ovelhas (...) e as cabras há aproximadamente 13 mil anos, seguido da domesticação das vacas quatro mil anos depois. Desde então o leite tornou-se um alimento indispensável para o homem. O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas essenciais para a saúde humana. Este leite apresenta três vezes mais proteínas em relação ao leite de cabra e de vaca, sendo aquelas consideradas proteínas de alto valor biológico contribuindo para uma melhor digestibilidade. Outra característica é a conformação estrutural e a quantidade de micelas de caseína e suas subunidades, que são assim como o leite caprino, menores que as do leite bovino, proporcionando menor sensibilização às pessoas alérgicas. Estudos sugerem que o leite de ovelha pode ser considerado o substituto ideal do leite bovino para pessoas alérgicas ao leite bovino devido ao elevado teor dos principais componentes do leite e minerais. Entretanto, foi verificado que anticorpos IgE de pessoas alérgicas reconhecem as αS1-caseína, αS2-caseína e β-caseína de leite ovino e caprino, mas caseínas do leite bovino são raramente ou não reconhecidas. Além disso, os polimorfismos genéticos das proteínas do leite estão associados com os parâmetros quantitativos e qualitativos e desempenham um papel importante na indução de diferentes graus de reação alérgica. A coloração do leite de ovelha é intensamente branca e homogênea, o que o difere do leite de vaca, pois essa característica está associada à ausência de β-caroteno pigmento precursor do retinol (vitamina A) impedindo que o leite tenha coloração amarelada como no caso do leite bovino. No leite ovino, o β-caroteno apresenta-se na forma convertida da vitamina A que não possui coloração amarelada e essa característica possibilita a produção de diferentes variedades de queijo. A caseína no leite de ovelha compõe 80% do total de proteínas do leite dos ruminantes, enquanto que está presente em 50% da composição proteica do leite equino e em menor porcentagem no leite humano. A caseína do leite de ruminantes difere com relação às características de tamanho, hidratação e mineralização. As micelas de caseína do leite de ovelha possuem maior mineralização e menor hidratação, sendo mais estáveis ao aquecimento quando comparadas à micela de caseína do leite de vaca. Outra importante característica refere-se à conformação molecular e sequencial de aminoácidos com impacto sobre sua digestibilidade, qualidade nutricional e termoestabilidade proteica. As proteínas do leite de ovelha consistem em elevada quantidade de caseínas (resistente ao calor) e proteínas do soro (sensível ao calor) responsáveis pela textura e viscosidade de iogurtes. Tecnologicamente, elas têm propriedades únicas que permitem a fácil conversão do leite em iogurte e queijos, não sendo necessária a adição de sólidos na produção do iogurte, como leite em pó, ou concentração dos sólidos do leite por tecnologia de membrana. Estudos com variantes da caseína do leite ovino representam uma abordagem eficaz para identificar a associação de características de importância econômica e melhorar raças para a produção de proteína do leite específica. As características da caseína no leite de ovelha são particularmente interessantes devido ao número elevado de polimorfismo, alterando a expressão de genes e influenciando o processamento de queijos. Em adição, enzimas presente no leite de ovelha possui atividade proteolítica e lipolítica (quebra de proteínas e lipídios). Elas auxiliam na maturação de queijos - resultando em compostos de aroma e sabor típicos, tornando-os únicos em suas características. O sabor e o aroma do leite de ovelha são suaves e adocicados além de possuir uma textura cremosa devido aos pequenos glóbulos de gordura que apresentam tamanhos menores que 3,5 µm. Esta peculiaridade no tamanho dos glóbulos gordurosos do leite ovino propicia que esse seja digerido mais facilmente. O leite ovino apresenta também altas concentrações de ácidos graxos poli-insaturados com benefícios à saúde como isômeros de ácido linoleico conjugado (CLA) presentes em maior concentração nesta matriz comparado ao leite bovino que são o cis-9 trans-11 e o trans-10 cis-12, responsáveis por ações anticarcinogênica, antiaterogênico e antiobesidade. Ainda com relação aos lipídios do leite de ovelha, as lipases têm um papel importante na produção de leite na glândula mamária. As lipases naturais do leite catalisam e hidrolisam os triglicerídeos, produzindo ácidos graxos livres (AGL). A atividade das lipases, em leite ovino, é cerca de um décimo das do leite bovino. Além disso, o padrão de hidrólise da gordura de leite por ovinos apresenta maior taxa em relação aos triglicerídeos - contendo ácidos graxos de cadeia média em relação aos ácidos graxos de cadeia longa. Os níveis de AGL em queijos de leite ovino são o resultado do processo lipolítico que ocorre durante o período de maturação. Alguns produtos lácteos derivados usando como matéria-prima o leite de ovelha - como iogurte grego e queijos - foram descritos como possuindo peptídeos inibidores da enzima conversora da angiotensina (ECA), sendo a maioria derivada da subunidade β-caseína. Também, alguns peptídeos derivados da κ-caseína, resultante da hidrólise de leite ovino pela pepsina, tripsina e quimotripsina, exercem atividade antioxidante. Em queijos tradicionais derivados de ovelha, como o Scamorza, foram verificados diversos peptídeos com ação inibidora da ECA e ação antibacteriana. Nesse contexto, o leite de ovelha é uma rica fonte de nutrientes e seu principal uso é na produção de queijos devido ao elevado conteúdo de extrato seco total, que contribui com alto rendimento da massa. Todavia, esta matéria-prima permanece inexplorada pela indústria de laticínios com uma visão de alimento funcional, visto que o leite e seus derivados são reconhecidamente ótimos carreadores de fibras prebióticas e bactérias probióticas - que trazem benefícios ao consumidor favorecendo saúde e bem-estar. Nesse contexto, o leite de ovelha apresenta-se como um alimento de grande potencial e uma valiosa alternativa para a indústria de laticínios - que pode aumentar a diversidade de produtos oferecidos ao consumidor.
