In order for students to succeed, especially in times of crisis like the Covid 19 Pandemic, they must be trained to be self-sufficient in their language studies. This research investigates using a self-access language learning strategy in an emergency virtual reading class during the covid 19 pandemics to improve language learners' Autonomy. It employed a descriptive correlational research design. The study involved 89 randomly selected language students in one University of Peru. Results of the study showed that the students can (...) utilize internet as their learning resource using devices they have. This shows that all of the students have devices to be used for their online and blended language learning. It is interesting to note the all the sampled students have access to internet for their online language learning. Hence the students have a motivated level of learning Autonomy in reading classes. As to the assessment of internet self-access reading skills of the students. This shows that the students have a favorable attitude towards using the internet in their reading lessons. It shows that the students have a fair level of technology acceptance and utilization for their language learning. Self-Access Skills in Reading was shown to be closely linked to Students' Learning Autonomy. This suggests that the relevant factors in the research have a positive correlation. This means that the students are more likely to adopt online self-access reading skills if they have a good attitude about learning Autonomy. This result shed light on the gap in addressing students' online language learning engagement in the COVID 19 era, particularly in the context of Peru. (shrink)

ABSTRACT: Virtue, the centerpiece of ancient ethics, has come under attack by virtue skeptics impressed by results of psychology experiments including Milgram's obedience studies. The virtue skeptic argues that experimental findings suggest that character structures are so fragile vis-å-vis situational factors as to be explanatorily superfluous: virtues and robust character traits are a myth, and should be replaced by situation-specific "narrow dispositions" (Gilbert Harman) or "local traits" (John Doris). This paper argues that the virtue skeptics' sweeping claims are ill-founded. (...) First, blending Aristotelian and contemporary insights about virtue, I reach a decision about a reasonable, non-straw definition of "virtue" and of "character trait." Next, I argue that explanations give by Lee Ross and Richard Nisbett for the Milgram findings covertly invoke character traits. Reflection reveals that more robust, cross-situationally consistent traits are needed for explanation of subject behavior, and that it is reasonable to suppose that such traits were in place.

REPRODUÇÃO ANIMAL: TRANSFERÊNCIA DE EMBRIÕES EM ANIMAIS, E A INDÚSTRIA DE EMBRIÕES NO BRASIL -/- ANIMAL BREEDING: EMBRYO TRANSFER IN ANIMALS, AND THE EMBRYO INDUSTRY IN BRAZIL Apoio: Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE E-mail: [email protected] WhatsApp: (82)98143-8399 -/- 1. INTRODUÇÃO A técnica da inseminação artificial tornou possível aumentar o impacto na descendência de touros geneticamente superiores em termos de produção láctea das filhas. Com a transferência de embriões é possível aumentar o impacto da fêmea sobre (...) a população das filhas. A transferência de embriões data de 1890, ano em que Heape obteve o nascimento de coelhos transferindo ovócitos fecundados de uma fêmea para outra. A partir de 1930, é repetida uma série de experiências para desenvolver a técnica e aplicá-la em ovinos, caprinos (1934) e bovinos (1951) como espécies mais idôneas para a reprodução. A Inglaterra e os Estados Unidos estabeleceram as bases para o comércio de embriões durante os anos sessenta e setenta. De forma resumida, a transferência de embriões implica na estimulação da produção de ovócitos mediante a aplicação de hormônios: cerca de 6-8 dias após a cobrição dessas fêmeas ou da sua inseminação artificial, os óvulos fertilizados são extraídos dos órgãos genitais da fêmea doadora por perfusão ou lavagem com soluções biológicas controladas e testadas, originando-se uma deposição dos gametas fecundados nas fêmeas receptoras que serão encarregadas de levar adiante a gestação e o parto sem influência sobre as produções do novo indivíduo. 2. MANEJO DAS FÊMEAS DOADORAS É relativamente fácil obter um embrião, uma vez que pode origina-se a partir do cio natural das vacas cíclicas. No entanto, a fim de otimizar a técnica, o normal é «superovular» a fêmea doadora e obter um número superior de gametas fecundadas após cada lavagem ou perfusão das genitais. A maioria das fêmeas doadoras são tratadas com gonadotrofinas (PMSG) ou com hormônios estimuladores da foliculogênese (FSH). Estes hormônios invertem a atresia normal de folículos permitindo uma maturação, que em condições normais não se realizaria. O mecanismo exato do funcionamento destas hormonas não é totalmente claro. A superovulação multiplica por um fator de 10 o número de ovócitos recuperados no caso das vacas, ovelhas e cabras, mas apenas por um fator 2 ou 3 no caso das porcas. Existe um acordo geral sobre a utilização das gonadotrofinas; a PMSG deve ser aplicada durante a transição da fase luteica para a folicular, ou seja, no 16º dia do ciclo. As doses de gonadotrofinas variam entre 1500 e 3000 UI em bovinos, aumentando a resposta e a variabilidade individual com o aumento da dose. A resposta ao tratamento varia de acordo em função de diversos fatores. Neste contexto, merecem especial atenção a espécie, a raça, a época e a conformação corporal do animal, bem como o lote de fabricação da preparação hormonal (quadro 7.1). Estudos demonstram que, nos bovinos, as raças de corte respondem melhor ao tratamento do que as raças leiteiras. Tabela 1: Doses de gonadotrofinas em UI -/- Espécie Dia do ciclo Crescimento folicular_ ___ PMSG FSH Ovulação _____ PMSG FSH Bovinos 8 – 10 1500 – 3000 20 – 50 1500 – 2000 75 – 200 Caprinos 16 – 17 1000 – 1500 12 – 20 1000 – 1500 50 – 75 Ovinos 12 – 14 1000 – 2000 12 – 20 1000 – 1500 50 – 75 Suínos 15 – 17 750 – 1500 10 – 20 500 – 1000 25 – 50 Coelhos — 25 – 75 2 – 3 25 – 75 2 – 3 Fonte: HAFEZ, 2004. O FSH também é utilizado para superovulação em várias espécies. Nos ovinos, injetam-se 2 mg desta hormona 12 horas antes da retirada das esponjas, aplicando-se mais três injeções, com um intervalo de 12 horas, até 24 horas após a retirada das esponjas, o que corresponde a um total de 8 mg de FSH injetados por tratamento e animal. Às vezes, e dependendo do país, existem dificuldades para a obtenção desse hormônio em condições de pureza adequada para que o tratamento proporcione o resultado esperado. Nas vacas dadoras devem ter passado mais de 50 dias após o último parto: também ser animais cíclicos, encontrar-se num nível nutricional elevado e em aumento, sem deficiências especificas alimentares. Existe uma indicação de suplementação das fêmeas doadoras com minerais essenciais antes do tratamento. 3. OBTENÇÃO DE EMBRIÕES Uma vez as fêmeas doadoras inseminadas, entre o sexto e o oitavo dia, procede-se a coleta dos embriões. Para isso, atualmente se utilizam cateteres de obtenção transcervical (tipo Foley, Rusch. etc.) munidos de uma bola insuflável na sua extremidade que permite criar um compartimento estanque na parte distal do córneo uterino e proceder ao arrasto dos embriões ali localizados. Para obter esta «lavagem» utiliza-se uma solução aquosa tamponada: o meio mais frequentemente utilizado é o tampão fosfato salino (PBS: pH = 7; PO = 280 - 290 mOsm/kg) suplementado com antibióticos e proteínas. Depois de recuperado o meio de lavagem, os embriões devem ser isolados do volume total, avaliados segundo critérios do Manual da Sociedade Internacional de Transferência de Embriões de acordo com seu estado de desenvolvimento. Código numérico para determinar o grau de desenvolvimento embrionário: N° 1: ovócito não fertilizado ou embrião de uma célula (1 dia). N° 2: Identifica embriões com 2 a 16 células (2-4 dias). N° 3: Identifica mórulas adiantadas (5-6 dias). N° 4: Identifica mórulas compactas de 6 dias de idade. N° 5: blastocisto adiantado (7 dias). N° 6: blastocisto (7-8 dias). N° 7: blastocisto expandido (8-9 dias). N° 8: blastocisto eclodido (9 dias) a partir do nono ou décimo dia o blastocisto já está fora da zona pelúcida. Além da classificação por estado de desenvolvimento, a referida Sociedade Internacional estabeleceu uma categorização dos embriões com base na qualidade dos mesmos. Assim os denomina: 1: excelente; 2: bom; 3: regular; 4: degenerado. Segundo as investigações de diversos autores especialistas no tema não devem ser transferidos embriões que não tenham sido classificados como excelentes ou bons. A obtenção dos embriões pode ser realizada em uma clínica, em unidades móveis especializadas, ou na própria fazenda. Em todo o caso, a doadora não deve apresentar quaisquer sintomas clínicos de doença, sendo esta responsabilidade direta do veterinário. O rebanho de onde provém a doadora deve estar livre de medidas cautelares sanitárias. Os técnicos devem estar adequadamente limpos e preparados para esta atuação, em um lugar tranquilo e que permita a colocação de equipamentos e material em condições limpas e seguras. 4. TÉCNICAS DE TRANSFERÊNCIA DE EMBRIÕES Recomenda-se que os embriões sejam transferidos o mais rápido possível depois da recuperação. A fêmea receptora deve apresentar um ambiente uterino o mais semelhante possível ao da fêmea doadora. Isto quer dizer que a receptora também será mantida num sistema de sincronização para que coincida o mais possível o estágio de desenvolvimento embrionário com seu correspondente estado uterino. A margem de assincronia para evitar efeitos indesejáveis é de ± 24 horas. Os métodos hormonais de sincronização são análogos aos das doadoras. As técnicas para a deposição dos embriões no seu novo habitat podem ser igualmente cirúrgicas e não cirúrgicas, mas devido aos problemas do uso de anestésicos em técnicas cirúrgicas, as transferências foram direcionadas para modelos não-cirúrgicos ou transcervicais. Este método é baseado na utilização do colo uterino de forma análoga como é realizada na inseminação artificial. Devido às relações entre o embrião e o ovário, as porcentagens de fertilidade são aumentadas ao serem depositadas no corno ipsilateral no ovário que se encontra ativo. A utilização desta técnica implica na obtenção de mais fêmeas gestantes. O uso de novilhas como fêmeas receptoras aumenta também a taxa de gestações a partir de uma maior facilidade de manejo, uniformidade na resposta hormonal e um custo mais baixo. O fator humano ou habilidade do técnico que realiza esta técnica também constitui um fator que influencia decisivamente no êxito da transferência, encontrando-se variações de 20 a 60% devidas a este fator. 5. CONTROLES SANITÁRIOS Com a utilização da inseminação artificial, verificou-se que, embora as tecnologias reprodutivas colaborativas fossem mais avançadas em termos de técnicas destinadas a aumentar a produtividade individual, da mesma forma, podem constituir um perigo de contaminação e de dispersão de doenças estrangeiras para o grupo ou rebanho para onde são transferidos os novos genes. Neste contexto, a transferência embrionária (TE) deve realizar-se tendo em conta os riscos que pode implicar uma manipulação inadequada. Uma vez mais, a Sociedade Internacional (IETS) na Reunião Regional da OIE (Oficina Internacional de Epizootias) estabeleceu as normas em 1985 para que a TE pudesse ser utilizada como meio para controle de doenças na pecuária. Para que a utilização da TE se realize sem risco para a saúde, é necessário ter em conta um certo número de regras e condições específicas que evitem os riscos de contaminação. O embrião está separado do meio externo por três barreiras de proteção: o corpo da mãe, o útero por si só e a terceira, e mais importante, pela zona pelúcida, a qual nos animais domésticos tem demonstrado ser totalmente impermeável a qualquer elemento patogênico, desde que fique intacta. Portanto, o risco de contaminação dos embriões pode vir por duas vias diferentes: a) Fatores extrínsecos - por invasão dos agentes patogênicos na cavidade uterina principalmente. Isto está relacionado com o estado sanitário médio do país, região ou rebanho de origem. b) Fatores intrínsecos - Segundo Thibier podemos considerar diferentes fontes potenciais de contaminação, que segundo o risco sanitário se classificam nas seguintes ordens: 1° Zigoto. 2° Penetração. 3° Absorção. 4° Armazenamento. 5° Exame. 6° Transferência. Os esforços para que os embriões se tornem livres de contaminação devem ser semelhantes aos que são efetuados com os animais vivos e com as doses seminais. O momento mais perigoso encontra-se entre a coleta das células fecundadas e a sua deposição, após seu exame, no trato reprodutivo da receptora. As condições em que o referido processo deve ser realizado encontram-se detalhadas no manual da Sociedade Internacional de Transferência de Embriões (IETS). 6. REGRAS DA IETS A transferência de embriões é a via mais segura para a troca de genes. No entanto, os técnicos devem esforçar-se por manter todas as regras e normas sanitárias para que a coleta e a manipulação dos embriões se realizem sob condições de absoluta garantia higiênica e sanitária. A transferência embrionária implica, pela primeira vez na história da medicina veterinária, que a vigilância sanitária não se aplica estritamente ao animal, uma vez que, na sua fase "in vitro", está inteiramente sob o controle do técnico. Por conseguinte, não haverá futuro para este tipo de biotecnologia se, paralelamente, não houver um elevado nível de garantia de que não «servirá» para não disseminar ou difundir doenças. As conclusões da Sociedade Internacional de Transferência de Embriões (IETS) na sua reunião anual de 14 de Janeiro de 1992 estabelecem, tendo em conta a revisão efetuada em 1991 pela Subdireção de Investigação e pelo Comitê de Importação e Exportação, uma classificação das doenças. Esta classificação corresponde às seguintes categorias: Categoria 1 - Doenças ou agentes de doenças para as quais foram recolhidas provas suficientes para afirmar que o risco de transmissão é negligenciável, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência: a) Leucose bovina enzoótica. b) Febre aftosa (bovinos). c) Língua azul (bovinos). d) Brucelose bovina. e) Rintraqueíte infecciosa bovina. f) Doença de Aujeszky. Categoria 2 - Doenças para as quais foram recolhidas provas substanciais que indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência, mas para as quais é necessário verificar os dados existentes através de novas transferências: a) Peste suína clássica. Categoria 3 - Doenças ou agentes de doenças para as quais os resultados preliminares indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados, entre a coleta e a transferência, mas para os quais essas verificações preliminares devem ser corroboradas por dados experimentais complementares "in vitro" e "in vivo": a) Peste bovina. b) Diarreia viral bovina. c) Língua azul (ovinos). d) Febre aftosa (suínos, ovelhas e cabras). e) Campylobacter fetus (ovinos). f) Doença vesicular do porco. g) Peste suína africana. h) Prurido lombar (ovinos). i) Haemophilus somnus. Categoria 4 - Doenças ou agentes de doenças que foram ou são objeto de trabalhos preliminares: a) Vírus Akabane (bovino). b) Estomatite vesicular (bovinos e suínos). c) Chlamydia psittaci (bovinos e suínos). d) Ureaplasma/micoplasmose (bovinos e caprinos). e) Maedi-visna (ovino). f) Adenomatosa pulmonar (ovino). g) Prurido lombar (caprinos). h) Língua azul (caprinos). i) Artrite e encefalite caprina. j) Parvovírus (suíno). k) Enterovírus (bovinos e suínos). I) Leptospirose (suíno). m) Herpesvírus 4 dos bovinos. n) Mycobacterium paratuberculose (bovinos). o) brucelose ovina. p) Doença de Border (ovinos). q) Vírus parainfluenza 3 (bovinos). r) Agente da encefalopatia espongiforme bovina. É interessante salientar que apenas seis doenças estão incluídas na categoria 1 (a mais segura). Isso não significa que as outras doenças tenham um risco maior, apenas indica que o risco de transmissão das doenças da categoria 1 é irrelevante, estatisticamente falando. É importante assinalar que as doenças mais importantes dos bovinos se situam na categoria 1. Isto significa que a incidência do embrião patogênico nos bovinos parece ser perfeitamente controlável, desde que sejam adotadas metodologias adequadas. Isto serve também como linha de defesa adicional para que o técnico centre sua atenção e cuidados entre a fase de obtenção e a de transferência. 7. SITUAÇÃO ATUAL DA TRANSFERÊNCIA DE EMBRIÕES ANIMAIS NO BRASIL O Brasil é um dos grandes responsáveis mundiais pela implantação da tecnologia na reprodução animal, sendo assim, o país conseguiu inserir-se no mercado internacional como um dos maiores produtores de embriões in vivo e in vitro. Nas últimas duas décadas, especialmente entre os anos de 1997 e 2017 o país passou por importantes transformações nesse segmento, dentre essas transformações vale destacar a posição relativa do Brasil no contexto mundial. O Brasil passou de referência regional, nos anos 1990, para se tornar o maior produtor mundial de embriões entre os anos 2012 e 2013, sendo líder no uso e na produção de embriões in vitro. Os primeiros registros da TE produzidos in vivo no Brasil datam da década de 1980, e uma década depois o país já tornara-se referência e detinha um mercado consolidado de produção e TE na espécie bovina. Não obstante, no ano de 1997 o país ainda era referência apenas no contexto regional, detendo 68,3% dos embriões transferidos na América Latina, esse percentual corresponde a 24.085 embriões de um total de 35.254 produzidos na América Latina. Esse percentual regional representa apenas 6,6% de toda a produção mundial de embriões in vivo, que produziu, em 1997, 360.656 embriões in vivo. Nos últimos anos, o mercado de embriões, principalmente o bovino, teve retração moderada de -2,5% ao ano entre 2003 e 2018, porém essa retração contrasta com o ligeiro crescimento observado a partir dos anos 2000 conforme figura 1: Figura 1: Produção de embriões bovinos no Brasil no período 1996-2018, total e por tecnologia adotada (in vivo[IVD] ou in vitro [IVP]). Em 2018, o mercado de embriões bovinos manteve-se inalterado se compararmos com os três anos anteriores, houve reduções nós segmentos de corte, leite e no total comparado ao ano de 2017. Em 2014, a produção de embriões para melhoramento do gado leiteiro teve seu ápice, porém de lá para cá esse mercado manteve-se estagnado como demonstra a tabela 2. Tabela 2: Produção de embriões bovinos no Brasil em 2018, estratificada por segmento e por tecnologia adotada (in vivo ou in vitro). 7.1 Crise, economia e mercado de embriões A indústria de embriões reflete, em maior ou menor grau, o momento da economia brasileira. Apesar do segmento agropecuário ser um setor em constante crescimento no país, ao qual, sem dúvidas, em meio a inúmeras crises mantém-se em constante crescimento. Porém vale ressaltar que esse mercado é emergente e está refletido em paralelo com os bens produzidos pelo país, como demonstra a figura 2. Figura 2: Produção de embriões bovinos e variação no produto interno bruto (PIB) no Brasil, no período 1996-2018. Cada vez mais o setor agropecuário do Brasil investe em novas tecnologias que maximizem o mercado e que melhore a produção dos animais seja no segmento corte ou leite. Segundo a OCDE, 1997, essa indústria da produção de embriões é um conjunto de novas técnicas e processos, frutos do desenvolvimento técnico-científico, que chega ao mercado e - o mais importante - o transforma. Logo, todas essas técnicas e biotecnologias visam, além da alta produção e do lucro, o melhoramento e a suplementação alimentícia da população mundial que está em crescente avanço. A evolução da tecnologia embrionária no país, seja para o melhoramento dos equinos para os esportes como as vaquejadas, hipismo, corridas, etc., onde são investidos tempo, dedicação e dinheiro para formar um novo animal que apresente força, conformação, conversão alimentar e que custa milhões, em muitos casos, não só dos equinos, mas também dos caprinos, ovinos, suínos e até mesmo os bovinos onde o mercado da TE é mais presente e aquecida, venceu os estigmas do “modismo” e o chamado “elitismo”, porém deve enfrentar novos desafios, em especial num contexto de forte concentração do mercado de genética e de concorrência globalizada. Mesmo com todos esses avanços e retrocessos, essa relativização dos números demonstra que um percentual bastante reduzido das fêmeas bovinas que estão em idade reprodutiva é utilizado para a técnica da transferência de embriões, e que o mercado brasileiro ainda tem um grande potencial de crescimento no setor de produção in vivo e in vitro. 8. RESUMO E PRIMEIRAS CONCLUSÕES Ao longo deste trabalho pretendi realizar uma revisão sumária sobre um tema de grande importância presente, e sobretudo futura; referir-me à transferência embrionária. Atualmente, esta técnica atingiu um grau notável de penetração, a nível prático, no gado leiteiro. No entanto, num futuro mais ou menos longínquo, não temos dúvidas quanto a esta técnica, pelas vantagens indubitáveis que apresenta a nível de avanço genético, que será aplicada em outras espécies úteis ao homem. Na minha exposição, tentei dar especial ênfase a dois aspectos: as técnicas de transferência, incluindo as normas IETS e os controles sanitários a serem efetuados. Por fim, a indústria brasileira de embriões mostrou-se em retrocessos e avanços, porém o mercado ainda têm grandes desafios a serem enfrentados ao longo dos anos, mas que serão sanados mediante as técnicas desenvolvidas pelos inúmeros centros de pesquisa embrionárias e seus especialistas. -/- Realização -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.

The twentieth-century obsession with meaning often fails to address the central questions: Why are we here? Where are we going? In this radical critique of modernity, Eugene (Rochberg-) Halton resurrects pragmatism, pushing it beyond its traditional formulations to meet these questions head on. Drawing on the works of the early pragmatists such as John Dewey, George Herbert Mead, and particularly C.S. Peirce, Meaning and Modernity is an ambitious attempt to reconstruct concepts from philosophical pragmatism for contemporary social theory. Through a (...) vigorous and illuminating dialogue with other perspectives in the social sciences, (Rochberg-) Halton reveals the value of the pragmatic attitude as a mode of thought, one which speaks to the contemporary hunger for significance in a world where rationalized technique has all too often severed subject and object from their living context... Throughout the work is a sustained critique of modern culture in which (Rochberg-) Halton brings his reconstruction of the pragmatic atttude to bear on twentieth-century thought and its counterparts in the expressive arts. His engaging analysis encompasses figures as diverse as Simmel, Freud, Wittgenstein, Schoenberg, Adolph Loos, Mumford, Melville, the "Vienna School of Fantastic Realism," and Doris Lessing. The author's semiotic approach to culture allows him to move freely and easily across many disciplines, including anthropology, sociology, communications, art, literature, and philosophy. This is a work of rare originality and power that is sure to provoke discussion, for Rochberg-Halton creates new premises for understanding the human web of meaning. In a review published in the London Times Literary Supplement, Charles Townshend said that (Rochberg-) Halton's, “answer to the dilemma of modernity is a still more striking synthesis, which he labels ‘critical animism’ (as distinct from primitive animism). Meaning and Modernity belies its conventional exterior: it is a passionate tract against the 'diabolical tyranny of the rational'...He pits his researches into the attitudes of Chicagoans to their household goods and to their city against the abstract semioticians who have emptied signs of their capacity to 'live objectively in the transactions people have with them'...Such humanism will probably strike his fellow social theorists as downright weird, but his work shows that the cracking shell of modernism will provide a rich intellectual agenda.”.

There is a widespread view that well-learned skills are automated, and that attention to the performance of these skills is damaging because it disrupts the automatic processes involved in their execution. This idea serves as the basis for an account of choking in high pressure situations. On this view, choking is the result of self-focused attention induced by anxiety. Recent research in sports psychology has produced a significant body of experimental evidence widely interpreted as supporting this account of choking in (...) certain kinds of complex sensorimotor skills. We argue against this interpretation, pointing to problems with both the empirical evidence and the underlying theory. The experimental research fails to provide direct support for the central claims of the self-focus approach, contains inconsistencies, and suffers from problems of ecological validity. In addition, qualitative studies of choking have yielded contrary results. We further argue that in their current forms the self-focus and rival distraction approaches both lack the theoretical resources to provide a good theory of choking, and we argue for an expanded approach. Some of the elements that should be in an expanded approach include accounts of the features of pressure situations that influence the psychological response, the processes of situation appraisal, and the ways that attentional control can be overwhelmed, leading to distraction in some cases, and in others, perhaps, to damaging attention to skill execution. We also suggest that choking may sometimes involve performance-impairing mechanisms other than distraction or self-focus. (shrink)

Integrated Information Theory (IIT) identifies consciousness with having a maximum amount of integrated information. But a thing’s having the maximum amount of anything cannot be intrinsic to it, for that depends on how that thing compares to certain other things. IIT’s consciousness, then, is not intrinsic. A mereological argument elaborates this consequence: IIT implies that one physical system can be conscious while a physical duplicate of it is not conscious. Thus, by a common and reasonable conception of intrinsicality, IIT’s consciousness (...) is not intrinsic. It is then argued that to avoid the implication that consciousness is not intrinsic, IIT must abandon its Exclusion Postulate, which prohibits overlapping conscious systems. Indeed, theories of consciousness that attribute consciousness to physical systems, should embrace the view that some conscious systems overlap. A discussion of the admittedly counterintuitive nature of this solution, along with some medical and neuroscientific realities that would seem to support it, is included. (shrink)

The ten original studies included in this Research Topic investigate selected assumptions and predictions of parochial altruism theory in detail. We, the editors, are convinced that their highly instructive findings will help researchers interested in parochial altruism, but also in intergroup psychology more generally, to gain a much more fine-grained understanding of the interplay of altruistic and spiteful motives in human decision making in the context of intergroup relations. The broad range of disciplines represented by the authors contributing to this (...) Research Topic and the variety of methods used in their studies are representative for the current interdisciplinary interest in parochial altruism. The most important insight that, in our view, can be derived from the works collected here is that human decision making in intergroup contexts is more complex than suggested by current theory. Thus, we hope that future theorizing on parochial altruism will be stimulated by the evidence gathered in this Research Topic. In this editorial, we briefly highlight central findings reported here, which, to us, appear most informative for prospective enhancements of parochial altruism theory. (shrink)

On the face of it, Maurice Merleau-Ponty’s views bear a strong resemblance to contemporary disjunctivist theories of perception, especially John McDowell’s epistemological disjunctivism. Like McDowell (and other disjunctivists), Merleau-Ponty seems to be a direct realist about perception and holds that veridical and illusory perceptions are distinct. This paper furthers this comparison. Furthermore, it is argued that elements of Merleau-Ponty’s thought provide a stronger case for McDowell’s kind of epistemological view than McDowell himself provides. Merleau-Ponty’s early thought can be used to (...) develop a unique version of epistemological disjunctivism that is worth consideration alongside contemporary views on perceptual knowledge.

Psychopaths appear to be ‘creatures apart’ – grandiose, shameless, callous and versatile in their violence. I discuss biological underpinnings to their pale affect, their selective inability to discern fear and sadness in others and a predatory orienting towards images that make most startle and look away. However, just because something is biologically underpinned does not mean that it is innate. I show that while there may be some genetic determination of fearlessness and callous-unemotionality, these and other features of the personality (...) may arise from developmental failures in the interpersonal reception of their emotions, needs and their sense of self. One is unlikely to be able to own inner experiences if shamed for having them, or if, having them, one does not know how to regulate and soothe. So psychopaths may learn to attend away and suppress them. Rather than a fully inherited difficulty, they may have become unable to reflect on inner states, so meta-emotions and self-reflective emotions like guilt and shame do not fully arise. They retain enough sensitivity to know their difference, and hide. I suggest that psychopaths are characterised by a nested sense of self, arising from the surprising effect of shame on these seemingly shameless characters. They do not have an integrated sense of self across context or across time or in relation to a generalised social other. With a nested sense of self, diminished intensity and scope of affective experience (in both directly experienced and vicarious forms) they lack textured access to a personal, owned and integrated past. Thus they lack the kind of access to the past required for a motivationally compelling planning of the future. They lack the emotional investment in the future that enables us to overcome the motivation to act opportunistically and myopically. These individuals live strangely in time. They have a fugitive sense of self and live nimbly among many pasts. They present an elegant and coherent mask to the person they are addressing in the moment and generate possible futures without conviction. (shrink)

Yoga is a unique form of expert movement that promotes an increasingly subtle interpenetration of thought and movement. The mindful nature of its practice, even at expert levels, challenges the idea that thought and mind are inevitably disruptive to absorbed coping. Building on parallel phenomenological and ethnographic studies of skilful performance and embodied apprenticeship, we argue for the importance in yoga of mental access to embodied movement during skill execution by way of a case study of instruction and practice in (...) two related traditions, Iyengar and Anusara. Sharing a pose repertoire, they are based on distinctive philosophical systems with different teaching styles and metaphoric structures. To address relations between pedagogy and practice in embodied expertise, and to investigate the reciprocal influences of embodiment and thought, we explore in detail the linguistically mediated learning context where practitioners work with yoga teachers. Here, the mind/body problem comes to practical life. We demonstrate the effects of words on bodies, as knowledge is literally incorporated. We show why interpersonal influence on our movement capacities is sometimes needed to enhance expertise. We theorize and identify ?signature patterns of tension? among practitioners. These patterns have four sources: ghost gestures, innate differences in bodily form, functional fusing, and signature patterns of affective experience, modulation and expression. These patterns of tension produce ?silent zones?, cognitively impenetrable actions, functional fusing of a skilful, compensatory form, and signature patterns of pain and damage. We show how instruction can disrupt these silent zones, enhancing mental and physical flexibility. (shrink)

This volume aimed to highlight narrative identities of European cities or city neighbourhoods that have been overlooked, such as mid-sized cities. These cities are neither small towns nor metropolises, cities that are now unveiling their appeal or specificity. The present special issue thus covers a range of representations of cities. The articles investigate more systematically how different texts deal with various cities from different experiential and fictional perspectives. The issue covers the geographical scope across Europe, from east to west or (...) vice versa, as well as a range of different works of national literature(s), but with a clear emphasis on mid-sized European cities that have until now been deemed as lesser-known, secondary, peripheral, ‘other’ cities that are in the focus of the research of the COST project Writing Urban Places.

This paper explores the usefulness of the 'ethical matrix', proposed by Ben Mepham, as a tool in technology assessment, specifically in food ethics. We consider what the matrix is, how it might be useful as a tool in ethical decision-making, and what drawbacks might be associated with it. We suggest that it is helpful for fact-finding in ethical debates relating to food ethics; but that it is much less helpful in terms of weighing the different ethical problems that it uncovers. (...) Despite this drawback, we maintain that, with some modifications, the ethical matrix can be a useful tool in debates in food ethics. We argue that useful modifications might be to include future generations amongst the stakeholders in the matrix, and to substitute the principle of solidarity for the principle of justice. (shrink)

I consider two attempts to combine realism with pluralism about the units of selection: Sober and Wilson’s combination of “model” and “unit” pluralism, and Sterelny and Griffiths’ “local pluralism”. I argue that both of these attempts fail to show that realism and pluralism are compatible. Sober and Wilson’s pluralism turns out, on closer inspection, to be a kind of monism in disguise, while Sterelny and Griffiths’ local pluralism involves a combination of realism and anti-realism about interactors, and the units of (...) selection, that is fundamentally unstable. My conclusion is that one must choose whether to be a realist or a pluralist in this area: one cannot be both. The question of which we should choose is a further question that I do not take a stand on. (shrink)

In elite sport, the advantages demonstrated by expert performers over novices are sometimes due in part to their superior physical fitness or to their greater technical precision in executing specialist motor skills. However at the very highest levels, all competitors typically share extraordinary physical capacities and have supremely well-honed techniques. Among the extra factors which can differentiate between the best performers, psychological skills are paramount. These range from the capacities to cope under pressure and to bounce back from setbacks, to (...) the knowledge of themselves, opponents, and the domain, which experts access and apply in performance. In the companion chapter on breadth and depth of knowledge in expert sport (see Chapter 11), we discussed the forms or kinds of knowledge deployed by elite athletes, and described some lines of research which seek to tap and study such expert knowledge (McPherson & MacMahon, 2008; McRobert, Ward, Eccles & Williams, 2011). In this chapter we focus more directly on questions about methods for measuring or more accurately assessing expert knowledge, in particular addressing a wider range of methods to help us understand what experts know. Suggesting that sport researchers can productively adopt and adapt existing qualitative methodologies for integration with more standard quantitative methods, we introduce and survey a number of areas of qualitative research in psychology.

There is widespread consensus that present patterns of consumption could lead to the permanent impossibility of maintaining those patterns and, perhaps, the existence of the human race. While many patterns of consumption qualify as ‘sustainable’ there is one in particular that deserves greater attention: virtual consumption. We argue that virtual consumption — the experience of authentic consumptive experiences replicated by alternative means — has the potential to reduce the deleterious consequences of real consumption by redirecting some consumptive behavior from shifting (...) material states to shifting information states.

Current challenges in medical practice, research, and administration demand physicians who are familiar with bioethics, health law, and health economics. Curriculum directors at American Association of Medical Colleges-affiliated medical schools were sent confidential surveys requesting the number of required hours of the above subjects and the years in which they were taught, as well as instructor names. The number of relevant publications since 1990 for each named instructor was assessed by a PubMed search.In sum, teaching in all three subjects combined (...) comprises less than two percent of the total hours in the American medical curriculum, and most instructors have not recently published articles in the fields they teach. This suggests that medical schools should reevaluate their curricula and instructors in bioethics, health law, and health economics. (shrink)

Healthcare systems across the globe are struggling with increasing costs and worsening outcomes. This presents those responsible for overseeing healthcare with a challenge. Increasingly, policymakers, politicians, clinical entrepreneurs and computer and data scientists argue that a key part of the solution will be ‘Artificial Intelligence’ (AI) – particularly Machine Learning (ML). This argument stems not from the belief that all healthcare needs will soon be taken care of by “robot doctors.” Instead, it is an argument that rests on the classic (...) counterfactual definition of AI as an umbrella term for a range of techniques that can be used to make machines complete tasks in a way that would be considered intelligent were they to be completed by a human. Automation of this nature could offer great opportunities for the improvement of healthcare services and ultimately patients’ health by significantly improving human clinical capabilities in diagnosis, drug discovery, epidemiology, personalised medicine, and operational efficiency. However, if these AI solutions are to be embedded in clinical practice, then at least three issues need to be considered: the technical possibilities and limitations; the ethical, regulatory and legal framework; and the governance framework. In this article, we report on the results of a systematic analysis designed to provide a clear overview of the second of these elements: the ethical, regulatory and legal framework. We find that ethical issues arise at six levels of abstraction (individual, interpersonal, group, institutional, sectoral, and societal) and can be categorised as epistemic, normative, or overarching. We conclude by stressing how important it is that the ethical challenges raised by implementing AI in healthcare settings are tackled proactively rather than reactively and map the key considerations for policymakers to each of the ethical concerns highlighted.

We consider an ethical dilemma in global health: is it ethically acceptable to provide some patients cheaper treatments that are less effective or more toxic than the treatments other patients receive? We argue that it is ethical to consider local resource constraints when deciding what interventions to provide. The provision of cheaper, less effective health care is frequently the most effective way of promoting health and realizing the ethical values of utility, equality, and priority to the worst off.

This chapter provides a gentle introduction to contextual emergence and its implications for the structure of the material world as well as implications for meaning in our world.

Cladism, today the dominant school of systematics in biology, includes a classification component – the view that classification ought to reflect phylogeny only, such that all and only taxa are monophyletic (i.e. consist of an ancestor and all its descendants) - and a metaphysical component – the view that all and only real groups or kinds of organisms are monophyletic. For the most part these are seen as amounting to much the same thing, but I argue they can and should (...) be distinguished, in particular that cladists about classification need not accept the typically cladist view about real groups or kinds. Cladists about classification can and should adopt an explanatory criterion for the reality of groups or kinds, on which being monophyletic is neither necessary nor sufficient for being real or natural. Thus the line of reasoning that has rightly led to cladism becoming dominant within systematics, and the attractive line of reasoning in the philosophical literature that advocates a more liberal approach to natural kinds, are seen to be, contrary to appearances, compatible.

I argue that the Conceptual Ethics and Conceptual Engineering framework, in its pragmatist version as recently defended by Thomasson, provides a means of articulating and defending the conventionalist interpretation of projects of conceptual extension (e.g. the extended mind, the extended phenotype) in biology and psychology. This promises to be illuminating in both directions: it helps to make sense of, and provides an explicit methodology for, pragmatic conceptual extension in science, while offering further evidence for the value and fruitfulness of the (...) Conceptual Ethics/Engineering framework itself, in particular with respect to conceptual change within science, which has thus-far received little attention in the literature on Conceptual Ethics/Engineering.

Pierre-Henri Castel provides a short but richly argued precis of his recently published two-volume 1,000-page masterwork on the history of obsessive-compulsive disorder. Having not read the as-yet-untranslated books, I write this commentary from Plato’s cave, trying to infer the reality of Castel’s analysis from expository shadows. I am unlikely to be more successful than Plato’s poor troglodytes, so I apologize ahead of time for any misunderstandings. Moreover, I cannot assess Castel’s detailed evidential case for his substantive theses.1 I thus focus (...) on some key philosophical issues that impinge on an area of my concern, the concept of mental disorder. Castel is a rare breed of French.. (shrink)

The rejection of behaviorism in the 1950s and 1960s led to the view, due mainly to Noam Chomsky, that language must be studied by looking at the mind and not just at behavior. It is an understatement to say that Chomskyan linguistics dominates the field. Despite being the overwhelming majority view, it has not gone unchallenged, and the challenges have focused on different aspects of the theory. What is almost universally accepted, however, is Chomsky’s view that understanding language demands a (...) theory that posits mental states that represent rules of language. Call this claim, following Cowie (1999), Representationalism or (R). According to (R), ‘‘[e]xplaining language mastery and acquisition requires the postulation of contentful mental states and processes involving their manipulation’’ (Cowie, 1999, p. 154). Although (R) is nothing more than the general assumption on which cognitive psychology is founded applied to the case of language, even it has had its detractors. Critics have argued that linguistic competence should not in fact be thought of as based on the possession of a body of linguistic knowledge but should be thought of, rather, as a kind of skill. This is an important challenge because one might be inclined to think that no recognizable form of Chomskyan linguistics could withstand the falsification of (R). In this paper we attempt to show that in fact (R) could be false without doing much damage to Chomskyan linguistics at all. Indeed, it is possible that the Chomskyan position could be made more coherent by adopting the view we will sketch. Our claim, therefore, is that critics of (R) might be right, but that this does not obviously make them serious critics of the Chomskyan program. (shrink)

In this paper, we defend Socratic studies as a research programme against several recent attacks, including at least one recently published in Polis . Critics have argued that the study of Socrates, based upon evidence mostly or entirely derived from some set of Plato's dialogues, is founded upon faulty and indefensible historical or hermeneutical technique. We begin by identifying what we believe are the foundational principles of Socratic studies, as the field has been pursued in recent years, and we then (...) show how the research programme that derives from accepting these principles is not defeated by any of the most common recent criticisms of it. Specifically, we argue that challenges to sorting Plato's dialogues by date, more general challenges to historicist interpretations of Plato's dialogues, as well as recent literary criticisms of Socratic studies all fail to undermine the research programme. We conclude with some thoughts about how and why Socratic studies has proved itself a valuable and fruitful research programme. (shrink)

Cushman, Young, & Greene (2010) urge the consolidation of moral psychology around a dual-system consensus. On this view, a slow, often-overstretched rational system tends to produce consequentialist intuitions and action-tendencies, while a fast, affective system produces virtuous (or vicious) intuitions and action-tendencies that perform well in their habituated ecological niche but sometimes disastrously outside of it. This perspective suggests a habit-corrected-by-reason picture of moral behavior. Recent research, however, has raised questions about the adequacy of dual-process theories of cognition and behavior, (...) which tend to distinguish categorically between fast, affect-laden, automatic, sometimes-unconscious, nearly-incorrigible mental processes and slow, rational, effortful, conscious, corrigible mental processes. Processes of one alleged type often have properties associated with the contrary type. For instance, rational processes can be emotional, and fast thinking can perform logical operations. In addition, the fast-slow binary transforms a continuous temporal scale into a dichotomous one, losing potentially important information along the way. While these problems are beginning to be addressed in some subfields of psychology, moral psychology has yet to grapple with them. In this theoretical paper, we argue that moral psychology needs a framework that accounts for our knowledge of both temporal and spatial (anatomical) dimensions of the brain basis of moral cognition and virtuous decision-making. We argue that methodologies with very fine-grained temporal granularity, such as electroencephalography (EEG), should be used to complement more frequently used methodologies such as functional magnetic resonance imaging (fMRI). We outline how this might be accomplished using generosity, gratitude, and integrity as a case study. (shrink)

Vor diesem Ausgangspunkt erarbeitet sie einen Explikationsvorschlag, der die Beantwortung einer ganzen Reihe von Fragen dieser klassischen philosophischen Debatte erlaubt. (shrink)

In this commentary, I critique three aspects of Emily Walsh's proposal to reduce the moral and legal weight of advance directives: (1) the ambiguity of its initial thesis, (2) its views about the ethics and legality of clinical practice, and (3) its interpretation and application of Ronald Dworkin’s account of advance directives and L.A. Paul's view on transformative experience. I also consider what Walsh’s proposal would mean for people facing the prospect of dementia. I conclude that our reasons to honor (...) many advance directives survive the move to a transformative experience framework. (shrink)

In discussing whether legal systems are necessarily coercive, legal philosophers usually appeal to thought experiments involving angels or other morally driven beings who need no coercion to organise their social lives. Such appeals have invited criticism. Critics have not only challenged the relevance of such thought experiments to our understanding of legal systems; they have also argued that, contrary to the intuitions of most legal philosophers, the ‘man on the Clapham Omnibus’ would not hold that there is law in a (...) society of angels because the view that law is necessarily coercive ‘enjoys widespread support among laypersons’. This is obviously an empirical claim. Critics, however, never systematically polled the ‘man on the Clapham Omnibus’. We boarded that bus. This article discusses findings from five empirical studies on the relationship between law and coercion. (shrink)

‘There is no place in the phenomenology of fully absorbed coping’, writes Hubert Dreyfus, ‘for mindfulness. In flow, as Sartre sees, there are only attractive and repulsive forces drawing appropriate activity out of an active body’1. Among the many ways in which history animates dynamical systems at a range of distinctive timescales, the phenomena of embodied human habit, skilful movement, and absorbed coping are among the most pervasive and mundane, and the most philosophically puzzling. In this essay we examine both (...) habitual and skilled movement, sketching the outlines of a multidimensional framework within which the many differences across distinctive cases and domains might be fruitfully understood. Both the range of movement phenomena which can plausibly be seen as instances of habit or skill, and the space of possible theories of such phenomena are richer and more disparate than philosophy easily encompasses. We seek to bring phenomenology into contact with relevant movements in psychological theories of skilful action, in the belief that phenomenological philosophy and cognitive science can be allies rather than antagonists.

This study was conducted to determine the effectiveness of utilizing the Dual-axis Solar Tracker in harnessing solar energy and storing it in lithium-ion batteries in terms of voltage and milliamps per hour gained. This study utilized two solar panel systems, the Static Solar Panel System and the Dual-Axis Solar Tracker and aimed to prove the significant difference generated by solar panel systems in terms of voltage and milliamps per hour. This study employed an Applied Experimental Research Design utilizing Arduino Uno, (...) light-dependent resistors, micro servos, and solar panels to create the Dual-Axis Solar Tracker. The data gathered from the electric quantities during the seven-day sun exposure were tabulated, analyzed, and computed using mean tests, standard deviation, and T-tests to find the significant difference between the two solar panels. Based on the analyses of the data, it was revealed that the Dual-Axis Solar Tracker was superior in terms of voltage and milliamps per hour generated compared to the Static Solar Panel System. Moreover, computations using the T-test found that in terms of voltage and milliamps per hour generated, there was a significant difference between the Dual-Axis Solar Tracker and the Static Solar Panel System. Based on the findings of the study, it is concluded that the utilization of the Dual-Axis Solar Tracker statistically increases the effectiveness of solar panels in harnessing energy generation.

The thesis that rationality consists in the straight-forward maximization of utility has not lacked critics. Typically, however, detractors reject the Humean picture of rationality upon which it seems based; they seek to emancipate reason from the tyranny of the passions. It is, then, noteworthy when an attack on this thesis comes from ‘within the ranks.’David Gauthier's paper ‘Reason and Maximization’ is just such an attack; and for this reason, among others, it is interesting. It is not successful, though. In defense (...) of this conclusion, we shall begin by relating the essentials of Gauthier's argument. Then we shall examine in some detail Gauthier's claim that the principle of straighforward max-imization fails to be self-supporting. We shall argue that Gauthier's defense of this claim is at best incomplete. Finally, we shall show that the fact that a normative principle is self-subverting or non-self-supporting does not entail that the principle is defective. (shrink)

In _Leviathan_, Hobbes embraces three seemingly inconsistent claims: (i) the unity of a multitude is secured only by the unity of its representer, (ii) assemblies can represent other multitudes, and (iii) assemblies are, or are constituted by, multitudes. Together these claims require that a representative assembly, itself, be represented. If that representer is another assembly, it too will need a unifying representer, and so on. To stop a regress, we will need an already unified representer. But a multitude can only (...) speak or act through its representer, and an assembly is a multitude, so any representing done by the assembly is actually done by this already unified, regress-stopping representer. That is, if (i) and (iii) are true, (ii) cannot be. I will argue that this inconsistency is only apparent and that we can resolve it without rejecting any of these three claims. We do this by appealing to a representer-as-decision-procedure meeting certain criteria. Such a procedural representer breaks the transitivity of representation such that the assembly it represents can properly represent some further multitude. I proceed in my defense of the procedural representer view by addressing a series of problems it faces, the solutions to which give us a progressively clearer picture of the criteria this representer must meet.

This paper offers an overview of consciousness and personal identity in eighteenth-century philosophy. Locke introduces the concept of persons as subjects of consciousness who also simultaneously recognize themselves as such subjects. Hume, however, argues that minds are nothing but bundles of perceptions, lacking intrinsic unity at a time or across time. Yet Hume thinks our emotional responses to one another mean that persons in everyday life are defined by their virtues, vices, bodily qualities, property, riches, and the like. Rousseau also (...) takes persons to be fundamentally determined by our socially-mediated emotional responses to one another, though unlike Hume or Locke, he has little interest in placing this account of persons alongside a larger discussion of the human mind and its operations. Developing this idea further, Kant argues that our moral commitments require that we must take ourselves to be free. The fundamental equality that Rousseau sought in the political order is, for Kant, a requirement that reason puts on all of us. (shrink)

Jacob Klapwijk’s book Purpose in the Living World? (Cambridge 2998) is examined with special attention given to the scholarly background from out of which it emerges as a significant contribution to reformational philosophical reflection. As an initial step to clarify some important issues raised by Klapwijk’s critical comments about Dooyeweerd’s “essentialist” concept of species, the article probes facets of the way Jan Lever incorporated reformational philosophical concepts into his biological theory and considers the 1959 review written by Herman Dooyeweerd of (...) Lever’s Creation and Evolution. The analysis focuses specifically upon the social responsibilities of these two scholars and the confrontation of their respective views. With the work of Lever and Dooyeweerd we sense something of the ambiguities when reformational philosophy confronts an evangelical scholasticism. This confrontation is an important facet of the context in which Klapwijk has set forth his discussion of creation and emergent evolution. Purpose is also the fruit of scholarly collaboration across disciplines, providing a welcome stimulus for a deepened understanding of the corporate character of the student vocation. (shrink)

In “Toward an Ontology of Commercial Exchange” [11], we proposed human readable definitions for terms that are central to an ontology of commercial exchange. This paper furthers that project in two ways. First, the definitions have been modified to be compatible with the Common Core Ontologies (CCO). CCO is used in a wide variety of domains including the industrial and military domains. Having a commerce ontology compatible with CCO allows data about the exchange of goods relevant to those domains to (...) be tagged with compatible ontologies. Second, we propose preliminary formalizations of these definitions, with the aim of informing the creation of an ontology which can be used to assist in reasoning over businessrelated data. (shrink)

A strong, but underexplored linkage exists between the current global order, world poverty and the politics of aid. Exploring this linkage, which is the key concern of this article, is crucial for a fuller understanding of the symbiotic injustice of the global order and the politics of aid. Using a conceptual thought experiment that portrays the framework of post-war global order as an intrinsically unjust “Global Games Arena”, I attempt a “vivisection” of the problematic relationship between the global order and (...) the politics of aid. In the real world, I follow decolonial scholars like Adom Getachew and Olúfẹmi O. Táíwò to argue that the modern and current global order and its social, economic and political structures are founded on the unfair gains of trans-Atlantic slavery and colonialism. The empirical and analytical consequence of this situation, the article shows, is that to make aid effective or altogether end its penurious impact in Africa in particular, would require, at first, a jettisoning or remaking of the current international order. In other words, I argue that aid would not be necessary in the absence of a world order that in fact requires aid to maintain a system of global injustice and inequality. (shrink)

There are unusual challenges in ethics for RAS. Perhaps the issue can best be summarised as needing to consider “technically informed ethics”. The technology of RAS raises issues that have an ethical dimension, and perhaps uniquely so due to the possibility of moving human decision-making which is implicitly ethically informed to computer systems. Further, if seeking solutions to these problems – ethically aligned design, to use the IEEE’s terminology – then the solutions must be technically meaningful, capable of realisation, capable (...) of assurance, and suitable as a basis for regulation. Thus, ethics for RAS is a rich, complex multi-disciplinary concern, and perhaps more complex than many other ethical issues facing society today. It is also fast-moving. This paper has endeavoured to give an accessible introduction to some of the key issues, noting that many of them are quite subtle, and it is not possible to do them full justice in such a short document. However, we have sought to counterbalance this by giving an extensive list of initiatives, standards, etc. that focus on ethics of RAS and AI, see Annex A. (shrink)

This paper proposes to reconstruct Boaventura de Sousa Santos' conception of "epistemologies of the south" both (a) as a critical theory aiming at denouncing the impoverishment of the epistemic field entailed by the normative imposition of a certain model of knowledge (what we call "the monoculture of reason"), and (b) as a long-term political project of a harmonic coexistence of different epistemologies ("an ecology of knowledges").

This article analyzes the evolution of aesthetic role of the nature in the Middle Ages from the point of view of the philosophical systems influence on the interpretation of the corporal as a legitim way to the knowledge of the truth. it studies the intimate approach of neo-platonism, the shaping of its premises in the rejection of physical beauty and the change that occured after the assimilation of Aristotelianism toward a naturalistic outsourcing of the intellectual and artistic interests.

This article analyzes the treatment of natural philosophy in the work of Thomas Aquinas from the point of view of assimilation of the Aristotelian physical corpus. It focuses primarily on the Aquinas’s defense of the conception of the fallibility of the natural reason, the provisional and revisable character of all physical theories, the necessity of intercultural dialogue to discover the truths about nature, and Aquinas’s role in the development of the skeptical attitude in scientific research of the mobile’s world.

We present an interdisciplinary approach to study systematic relations between logical form and attacks between claims in an argumentative framework. We propose to generalize qualitative attack principles by quantitative ones. Specifically, we use coherent conditional probabilities to evaluate the rationality of principles which govern the strength of argumentative attacks. Finally, we present an experiment which explores the psychological plausibility of selected attack principles.

This Note offers a normative critique of cost-benefit analysis, one informed by deontological moral theory, in the context of the debate over whether tort litigation or a non-tort approach is the appropriate response to mass harm. The first Part argues that the difference between lay and expert intuitions about risk and harm often reflects a difference in normative judgments about the existing facts, rather than a difference in belief about what facts exist, which makes the lay intuitions more defensible. The (...) second Part considers how tort has dealt with this divergence between lay and expert perspectives. It also evaluates how tort's approach has differed from that of public law approaches to accident law, such as legislative compensation and risk regulation by administrative agencies. Ultimately, tort's ability to recognize the value of lay intuitions supports retaining the tort perspective as part of our societal arsenal of responses to risk and harm. This ability can also support a pro-tort perspective in two practical debates in the arena of tort law: that over preemption of tort law by administrative agency judgments, and that over access to tort recovery as part of a no-fault system.

This article encourages a reconsideration of Christian sociology. It explains how deism makes a decisive impact in the theoretical foundations of the discipline. Dutch neocalvinistic philosophy in its North American immigrant setting after World War II issued a challenge which drew attention to the dogmas of deism implicit in sociology, but this challenge has not been met. Christian sociology, however, still retains its God-given vocation to find ways to encourage people everywhere to positively form complex differentiated social settings in the (...)
