hroughout medieval Christianity, religious works of art emerged to illustrate the teachings of the Bible for the largely illiterate population. What, then, is the significance of the psychoactive mushrooms hiding in plain sight in the artwork and icons of many European and Middle-Eastern churches? Does Christianity have a psychedelic history? -/- Providing stunning visual evidence from their anthropological journey throughout Europe and the Middle East, including visits to Roslyn Chapel and Chartres Cathedral, authors Julie and Jerry Brown document the (...) role of visionary plants in Christianity. They retrace the pioneering research of R. Gordon Wasson, the famous “sacred mushroom seeker,” on psychedelics in ancient Greece and India, and among the present-day reindeer herders of Siberia and the Mazatecs of Mexico. Challenging Wasson’s legacy, the authors reveal his secret relationship with the Vatican that led to Wasson’s refusal to pursue his hallucinogen theory into the hallowed halls of Christianity. -/- Examining the Bible and the Gnostic Gospels, the authors provide scriptural support to show that sacred mushrooms were the inspiration for Jesus’ revelation of the Kingdom of Heaven and that he was initiated into these mystical practices in Egypt during the Missing Years. They contend that the Trees of Knowledge and of Immortality in Eden were sacred mushrooms. -/- Uncovering the role played by visionary plants in the origins of Judeo-Christianity, the authors invite us to rethink what we know about the life of Jesus and to consider a controversial theory that challenges us to explore these sacred pathways to the divine.

Parental factors impact students’ self-concept and academic performance during the pandemic. Thus, this study determined the students’ self-concept and academic performance and the parental factors related to it. The research design was descriptive-correlational, and 500 nonrandom college students in West Philippines participated in the study. Researcher-made instruments were used, which were subjected to reliability and validity evaluation. Data were collected online from June 2021 to July 2022 and were analyzed using descriptive (frequency counts and percentage) and inferential statistics (Spearman correlation). (...) Results revealed a positive self-concept and satisfactory academic performance among the students. Besides, parental factors such as educational attainment and school/classroom involvement are significantly related to self-concept and academic performance. Further, self-concept is significantly associated with academic performance. This shows that some parental factors are vital in developing the student’s self-beliefs and supporting their studies and academic endeavors amid the COVID-19 pandemic. Future studies may consider more factors related to academic achievement and self-concept. Other researchers may find the mediation or moderation effect of self-concept between parental factors and students’ scholastic achievement. (shrink)

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.

One of the ṣaḥābīs of Prophet Muḥammad is ʿUrwa b. Masʿūd from the Ṭāʾif tribe of Thaqīf. He belongs to the Ahlâf part of the Thaqīf tribe and he is the ruler of this part. ʿUrwa’s ancestry is known without any controversy until Kasî (Thaqīf). According to a narrative his epithet was Abū Yaʿfur and another of his epithet was Abū Masʿūd. Father of ʿUrwa an important person too. He is one of the leaders of his tribe and he commanded (...) his part (Aḥlāf) in wars of Fijār. Mother of ʿUrwa is Subay’a bt. ʿAbd Shams from Banū Umayya. In this way ʿUrwa has kinship both with Banū Umayya and Prophet Muḥammad. So ʿUrwa has a very important position because of his lineage, his mother and father. Thefore, his connections with Mecca and Quraysh strengthens his position. In our sources there is no information about his dates of birth and death. It is likely to be over middle age when he became a muslim, considering that he was the leader of his tribe and his son become a muslim after he died. There is too little information about weddings of ʿUrwa. According to narratives, he had ten wives before becoming Muslim. After becoming a Muslim Prophet Muḥammad warned from him to prefer four out of ten wives. One of his four wives is the daughter of Abū Sufyān. Howev-er, there is no information about the names of his wives. Names of his sons: ʿĀṣim, Abū Murra, Abū Mulayḥ, Dāwūd, Hammām and Hishām and names of his daughters: Umm Saʿīd (married with Ḥaẓrat ʿAlī) and Ḥalīma. We could see he served as embassy before the treaty of Hudaybiyah. His embassy duty shows us the superiority of his position. Also, this embassy duty was very effective at peace negotiations. He mentioned kinship relations which connects about Mecca. He said that it could be beneficial to talk to Prophet Muḥammad himself. The Meccans mentioned about their trust in ʿUrwa. During the time of his embassy, he expressed that both sides should be away from war. In this context, he told the Meccans: The people around Prophet Muḥammad are very loyal to him and he told to Prophet Muḥammad: People around him could disintegrate easily. This mission shows us he is intelligent, respectable and had high persuasion skills. ʿUrwa, observed loyalty of ṣaḥābīs to Prophet Muḥammad. He confessed this loyalty can not be for any ruler. This observa-tion probably affected ʿUrwa’s conversion to Islam. Because of the conquest of Meccah and the events that followed, the people of Ṭāʾif were very worried. Because of this reason people of Ṭāʾif took part in the side of Hawāzin’s and they bat-tled with Muslims. In this time they sent ʿUrwa b. Masʿūd and Ghaylān b. Salama to the city of D̲j̲aras̲h̲ of Yemen, to learn about some war machines and techniques. Therefore they did not join wars of Hunayn and Ṭāʾif. Prophet Muḥammad ended the siege of Ṭāʾif and went to Medina. Meanwhile, ʿUrwa and his friend returned from Yemen. According to narratives when the Prophet Muḥammad returned Medina or he was way in Medina ʿUrwa visited him and became Muslim. Some people tell about the date of ʿUrwa’s being Muslim at before or after Abū Bakr’s emirate of Hadj. However, when the narrations are examined, it can be said he became Muslim after four or five months from Prophet’s siege of Ṭāʾif and before three or four months from Tabūk expedition of Rabīʿ al-awwal or “Rabīʿ al-ākhir” (July or August) in the year 9/630. As for the conversion of ʿUrwa, basic sources report that “Allah, inspired Islam to the heart of ʿUrwa and he changed his situation. He went to the Messenger of Allah and he became Muslim.” They do not give a specific reason. But after this period the narratives tell the reason for ʿUrwa’s becoming a Muslim as due to an experience he had while travelling to Najrān for trade. In this travel, two mysterious young girls and the priest in Najrān said the last prophet came and ʿUrwa must be subject to him and ʿUrwa became Muslim after he returned. But this narrative is prob-lematic with regard to evidence and text. After being Muslim, ʿUrwa wanted permission from the Prophet to invite his tribe to accept Islam. The prophet did not want to accept this at first. Because the people of Ṭāʾif had an arro-gant stance against Islam, and he said that the people of Thaqīf could kill ʿUrwa. Eventually ʿUrwa went to his hometown with permission of Prophet and invited people to Islam and they did not accept this invitation and cursed ʿUrwa. The next morning ʿUrwa read adhan of fajr and people of Ṭāʾif killed him. ʿUrwa b. Masʿūd was likened to Prophet Jesus by the Prophet Muḥammad. It is generally accept-ed that ʿUrwa b. Masʿūd el-Thaqafī is “one of the biggest from two cities” expressed in sūra Zukhruf. Only two weak narrations were reported of Urwa who could live as a Muslim for a few days and was matyred by his tribe. (shrink)

Russell’s second philosophy of time (1899–1913), which will be the subject of this paper, is of special interest for two reasons. (1) It was basic to his New Philosophy, later called the “philosophy of logical atomism”. In fact, this philosophy didn’t initially emerge in the period of 1914– 1919, as many interpreters (e.g. A. J. Ayer) suggest, but with the introduction of Russell’s second philosophy of time (and space). The importance of Russell’s second philosophy of time for his early and (...) middle philosophy can be seen from the fact that it survived the dramatic changes in his philosophy of August–December 1900, and of July 1905. There is of course no surprise about this point: it served as their fundament. (2) Russell’s second philosophy of time is a locus classicus of all so called B-theories of time which define it in terms of the relations of before, after and simultaneous between events or moments. 20th century philosophy; absolute theory of time; theory of time; order; relation; relationist theory of time; B-series.

This is a revised version of the introductory essay in C. Eschenbach, C. Habel and B. Smith (eds.), Topological Foundations of Cognitive Science, Hamburg: Graduiertenkolleg Kognitionswissenschaft, 1994, the text of a talk delivered at the First International Summer Institute in Cognitive Science in Buffalo in July 1994.

Abstract: Northern state, Sudan is extremely affected by desertification and Salinization processes, there for this study aimed to investigate an effective method to improve the salt affected soil. Two field experiments were carried out in two successive seasons ( July 2005 – June 2006 ) at Dongola University farm, in the North State to investigate the effect of irrigation frequency ( 7 and 14 days ) and farm yard manure (M0 , M1 , M2 , andM3 ) on salt leaching (...) undersaline – sodic soil . The experiment was designed in spilt – plot design , where irrigation frequency was assigned in the main plots ( 6x28m) and farm yard manure were the sub – plots ( 6x7m) .The total cultivated area was 1342m2 for each experiment. The quantity of water applied was estimated according to Jensen andHaise (1963 ) . The total water quantity was the same by the end of the season. In general , the result indicated that irrigation frequency of 7 days enhanced salt leaching from the root zone. Generally , the reduction in electrical conductivity ( ECe ) and sodium adsorption ratio ( SAR ) due to irrigation frequency was more effective in 7 day irrigation interval as compared with 14 – day irrigation interval . the data obtained indicated that the addition of FYM 10 ton/feddan, significantly degreased the (ECe) and the (SAR) and leached them below the root zone. So, we can conclude that the efficiency of salt leaching is markedly affected by irrigation frequency and yard manure. (shrink)

INTRODUÇÃO Segundo Pond (1975), os antepassados mais remotos dos suínos remontam há 40 milhões de anos, e parece que seu parente mais distante é o porco-do-cabo (Orycteropus afer), que viveu na região da Etiópia. Este é da ordem dos tubulidentados com focinho e orelhas alongadas, de hábitos noturnos e que se alimenta de insetos e raízes. Embora não exista um consenso unânime ao respeito, estima-se que a domesticação do porco doméstico atual iniciou-se na Europa entre os anos 7.000 e 3.000 (...) a. C., embora investigadores chineses reivindiquem a origem chinesa do porco doméstico atual que havia iniciado na região sul do país entre o ano 10.000 a. C. Aceita-se que a domesticação tenha se realizado de maneira lenta e progressiva e que os primeiros porcos eram pequenos e estavam em rebanhos pouco numerosos. Os porcos atuais pertencem ao gênero Sus e compreendem os porcos asiáticos (Sus vittatus) de tamanho pequeno; os célticos (Sus scrofa) provenientes do javali europeu e os porcos ibéricos (Sus mediterraneaus) de origem africana, de tamanho maior que os anteriores e introduzidos em todas as regiões do sul da Europa. A capacidade de adaptação do porco às diferentes condições climáticas determinou que sua exploração se realize em todos os continentes e em quase todos os países do mundo, com exceção daqueles onde, por razões de ordem cultural e religiosa, a sua exploração é vedada. O seu caráter cosmopolita está relacionado a sua grande capacidade de adaptação aos variados regimes alimentares, já que sua qualidade de onívoro lhes permite transformar diferentes produtos e subprodutos, alimentando-se tanto de recursos vegetais quanto de animais. Pode ser explorado de forma tradicional com recursos limitados ou de forma intensiva, combinando as mais sofisticadas técnicas de manejo relacionado à alimentação, sanidade, reprodução, transformação e comercialização. POPULAÇÃO MUNDIAL DE SUÍNOS DE RAÇAS LOCAIS Não existem estatísticas diferenciadas para a população mundial de suínos de raças locais. A Organização das Nações Unidas para a Agricultura e Alimentação (FAO), estima que a população mundial de suínos em 2018 foi de 781,3 milhões de cabeças, que compreendem 460 milhões de cabeças na Ásia, 155 milhões na União Europeia, 75 milhões na América do Norte, 70 milhões na América Central e do Sul e 21 milhões de cabeças na África e Oceania. Observe o anexo e o gráfico: Figura 1: População mundial de suínos de produção industrial em 2018. Fonte: FAO, 2019. -/- G 1: Efetivo suíno mundial em 2018. FAO, 2019. G 2: 11 maiores países criadores de suínos em 2018. FAO, 2019. A elevada população de suínos no continente asiático é um indicador da importância que estes animais têm na alimentação dos habitantes dessa região. Na China, que possui o maior efetivo suíno do mundo, 440 milhões (FAO, 2019), os porcos estão geralmente incorporados sob sistemas integrados com a agricultura. O mesmo ocorre no Vietnã, onde a maior parte dos milhões de cabeças também estão em sistemas tradicionais de produção. Sobressaem, em importância, as raças Mong Cai, Thouc Nhieu e Ba Xuyen ambas com milhares e até milhões de exemplares cada uma. Na Indonésia, dados desatualizados obtidos por Aritonang et. al. 1993, a população de suínos chegou a 8,6 milhões de cabeças, e que esses porcos locais representavam mais de 95% da população de distritos como Deli Serdang, North Tapanuli e Nias em Sumatra. As raças asiáticas, com as suas múltiplas características, foram objeto, nos respectivos países, de programas especiais para melhorar a sua produção. Outros países, principalmente a França e os Estados Unidos da América, iniciaram estudos sobre as raças asiáticas com o propósito de aproveitar alguns fatores genéticos próprios destas, como a alta fertilidade. Na Europa, países como Portugal e Espanha, tentaram conservar alguns genótipos de raças locais. Segundo dados do Anuário Estatístico do Ministério da Agricultura (1985), citado por Paz Saez e Hernández Crespo (Sf.), a Espanha tinha em 1996 uma população suína local estimada em 1,5 milhões de cabeças das raças ibérica, celta, morcego e suas cruzes. As referências relativas à presença de suínos locais são escassas na África. Sarniguet, citado por D’Orgeval Dubouchet (1997), dava conta que em 1985 existiam apenas 564 porcos exóticos, o que põe em evidência a importância do rebanho local. No Burkina Faso (Kabore, 1996), a exploração de suínos ocupa o quarto lugar entre as explorações animais e, em 1994, contava com uma população de 552,3 mil cabeças, sendo ao dizer da autora, «a raça local de maior presença». Tal como noutros países, a informação é genérica e a maioria dos autores sustenta que os suínos locais apresentam uma grande variedade e que se distinguem em três tipos: pequenos, grandes e pesados. Os genótipos são de grande rusticidade e de baixa produtividade, mas de boa adaptação às mais variadas formas de manejo e sistemas de alimentação. A América Latina, conta com uma população significativa de porcos locais, provenientes dos porcos introduzidos por Colombo, em sua segunda viagem ao Novo Continente em 1493, e de outros que foram introduzidos posteriormente à medida que se generalizou a conquista do continente. Infelizmente, não existem dados precisos sobre a população de suínos locais em cada um dos países e os dados oficiais generalizam, quando sustentam que estas populações são «maioritárias». Na Colômbia, um trabalho realizado por C. Espinosa (comunicação pessoal em 1997) indica que o porco local, conhecido como crioulo ou "zungo" provém dos porcos ibéricos conhecidos como lisos ou pelados e que estes localizaram-se inicialmente no departamento de Córdoba e depois no resto do país. Demonstra que os suínos locais estão a desaparecer rapidamente em consequência da introdução de "raças modernas". No entanto, não se quantifica o seu número e sustenta-se que, até há algumas décadas, constituíam a maioria dos animais explorados pelos camponeses das regiões afastadas. Na Bolívia, Amurrio (1996) indica que, segundo o Instituto Nacional de Estatísticas, a população suína total era de 2,2 milhões de cabeças, que forneceram 25% da carne consumida. Embora não precise da população local, considera-se que este genótipo «é menor do que no passado» e que os animais que se encontram com maior frequência provém de cruzamentos com raças importadas. No Equador, os trabalhos realizados por Alvarado e Gómez (1982) e por Molina (1988-1995), põem em evidência que os rebanhos locais estão compostos em 50% dos casos por 1-4 mães e que contribuem com 25% da produção nacional de carne e com 30% da gordura. Iaso indica a sua importância na alimentação. Em um trabalho realizado por Benítez (1995), descobriu-se que no país existiam 2,1 milhões de suínos explorados no sistema tradicional, e que desta população tão somente de 3 a 5%, segundo a região, eram animais provenientes das raças ibéricas. Na zona central e no sul do país encontram-se genótipos provenientes dos suínos ibéricos conhecidos como «runas», «jungas» ou «crioulos». A população de suínos tende a aumentar em quase todos os países da América Latina como resultado dos cruzamentos entre as populações de raças ibéricas e as raças modernas. No Equador, há uma população de porcos de 2,7 milhões de cabeças (FAO, 2000). O Banco Central do Equador, no Boletim Anuário 19 (1997), assinala que em 1996 existiam 2,7 milhões de suínos e que produziram 36 mil toneladas de carne. Quanto ao Brasil, a deficiência de dados acerca do plantel de suínos locais é resultado das grandes críticas relativas aos sistemas de produção tradicionais e integrados. No entanto, dados obtidos pela FAO revelam que o efetivo total de suínos em 2018 foi de 38,8 milhões de cabeças, fazendo do país o quarto maior criador e produtor de suínos do mundo, gerando movimentação de toda cadeia produtiva de R$ 150 bilhões de reais, um produto bruto de R$ 62 bilhões de reais e 1,1 milhões de empregos diretos e indiretos (ABCS, 2016). É indiscutível que, pelas suas características zootécnicas e por terem sido explorados de maneira tradicional, sem investimentos maiores de tempo, recursos e tecnologia, os suínos locais não foram objeto de muitos estudos que permitam conhecer o seu verdadeiro potencial genético e a sua capacidade produtiva. -/- IMPORTÂNCIA DOS SISTEMAS DE PRODUÇÃO INTEGRADOS Desde os primórdios da civilização, o homem tem tentado obter alimentos suficientes. Infelizmente, em muitos países, por variadas razões, ainda há muita gente mal alimentada e que sofre com a fome. No início do século XXI, a subordinação afetou 800 milhões de habitantes e mais de 100 milhões têm uma alimentação desequilibrada (FAO, 1995). Enquanto, nos países industrializados, os excedentes produtivos tornam-se elementos desestabilizadores da economia e dão lugar à especulação. Geralmente, os animais, principalmente os monogástricos, são considerados como concorrentes do homem por recursos alimentares. Esquece-se que são também importantes transformadores de produtos e subprodutos não comestíveis diretamente pelos seres humanos e que uma adequada e racional exploração deles pode realizar-se a complementação das necessidades alimentares das populações. Os sistemas produtivos compreendem uma série de elementos que interagem com a finalidade de aumentar a produção. Os sistemas pecuários integram um território, as forragens e outros alimentos, as práticas, os rebanhos, as instalações, os recursos financeiros e a comercialização. Diversas espécies animais que coexistem na mesma exploração constituem subsistemas (Gibon, 1981). Os sistemas integrados de produção permitem a participação de diferentes espécies domésticas, incluindo os suínos. Sua capacidade de transformação digestiva assegura a eliminação, segundo Ensminger (1976), de até 36 toneladas de excrementos para cada 1.000 kg de peso vivo por ano, isto é, 3.600 kg anuais de excremento por animal de 100 kg. Por exemplo, um animal de 45 kg, peso aproximado dos porcos locais, elimina diariamente 3,5 kg entre fezes e urina, conforme Jensen (1974). Estes resíduos são de grande utilidade para manter a fertilidade dos solos, bem como para servir de alimento a espécies com grande poder de transformação como os peixes (Little e Edwars, 2001) e palmípedes, além de servir para o mercado de produção de gás através dos biodigestores. Nos sistemas tradicionais, a sua utilização adequada permitiu a exploração de sistemas integrados com várias espécies de peixes como a tilápia (Tilapia spp.), carpas (Cyprinus spp.) e peixes-gato (Clarias spp.). Segundo Holmess (1991), entre cinquenta e sessenta suínos produzem suficientes efluentes para satisfazer as necessidades alimentares de 20 mil a 50 mil peixes por hectare, com uma produção anual de 3,5 a 5,0 ton./ha/ano de peixes. Em algumas explorações, em particular nos países asiáticos, os suínos desempenham um papel importante nos sistemas integrados. Além de transformar produtos e subprodutos agrícolas e agroindustriais, suas excreções recicladas para a agricultura são utilizadas para gerar biogás em biodigestores (FAO). A energia produzida por este meio, satisfaz as necessidades das famílias tanto para a preparação de alimentos, usos artesanais e até mesmo aquecimento de moradias. Holnees (1991), sustenta que sete porcos são suficientes para produzir o biogás necessário como combustível para uma família de cinco membros. A necessidade de aprofundar-se em estudos relacionados com a integração de sistemas, é mais evidente se tiver em conta que os sistemas intensivos requerem um elevado investimento econômico e tecnológico, e que muitas vezes originam uma grande contaminação. Chirgwin et. al. (1997) expressam que no balanço de «eficiência» esses fatores se mostram pouco rentáveis, se considerar a «energia consumida em insumos e serviços requerida para gerar o produto». As experiências acumuladas nos países asiáticos (FAO), e em alguns outros países da África e da América Latina, mostram que os sistemas integrados de produção estão mais próximos de cumprir com os postulados universais de produzir para garantir um adequado nível nutricional da população, através da utilização de tecnologias que não alteram nem deterioram o ambiente. Não há dúvida de que ainda são necessários grandes esforços como o empreendido pela FAO, que permita a combinação de tecnologias, de programas sanitários, de produção e de marketing. A abordagem holística deve constituir a base de futuros programas para uma adequada utilização da energia para converter o porco, e outros animais, em transformadores de produtos e subprodutos com rendimento para a população humana. CONCENTRADORES DE NUTRIENTES A conformação gástrica do porco, em particular a estrutura anatômica do seu intestino e a sua qualidade de onívoro, permite-lhe consumir todos os tipos de alimentos. Dotado de um estômago com uma capacidade de armazenamento de 6 kg (para um porco de 100 kg), dispõe de um intestino delgado que pode atingir até 14 vezes o comprimento do corpo do animal e de um fígado volumoso que permite um adequado metabolismo, garantindo uma grande capacidade de transformação dos alimentos e de assimilação. Proporcionalmente, tem um intestino equivalente ao dobro do de um homem adulto (Serres, 1973). No porco, a baixa transformação do azoto inorgânico é compensada pela disponibilidade de uma variada e rica microflora intestinal, localizada ao longo do intestino, o que lhe permite uma excelente utilização de amidos e de gorduras, provenientes de cereais e leguminosas. Os porcos nos sistemas tradicionais, na maioria das vezes, recebem uma alimentação desequilibrada. No entanto, a sua rusticidade e o seu instinto de sobrevivência permitem-lhes encontrar uma dieta que assegure, além de sua mantença, a sua reprodução e produção, fornecendo energia e proteínas à dieta humana. Esta grande capacidade transformadora de alimentos é o que permitiu ao porco, de maneira ancestral e às novas raças, a integração nos sistemas industriais com grandes benefícios econômicos, como consequência da melhoria das taxas de conversão alimentar. SUÍNOS LOCAIS E A ECONOMIA RURAL A economia dos camponeses, em particular dos países em desenvolvimento, é majoritariamente rural, com disponibilidade de pequenas parcelas e onde os cultivos e as espécies animais exploradas são adaptadas às mais variadas condições climáticas. Nestas unidades de produção, a tecnologia utilizada é ancestral, os ciclos produtivos são regidos pelo costume, os calendários astrais de suas respectivas culturas e condicionados às condições climáticas. A tecnologia utilizada não foi inovada senão de uma forma muito parcial. Não são efetuados investimentos em fatores de produção externos e, muitas vezes, grande parte das colheitas perdem-se durante o armazenamento. Em muitos casos, apesar da grande variedade de culturas por parcela (CATER, 1982), a produtividade é baixa e apenas satisfaz as necessidades familiares com escassos remanescentes para ao câmbio ou «troca» e com uma quase nula disponibilidade de excedentes para a comercialização (Benitez et. al., 1987). A pecuária, nestas unidades de produção, caracteriza-se pela diversidade de espécies, entre as quais predominam os animais menores: porcos, cabras, galinhas, patos, e espécies autóctones, como os cuyes e camelídeos nos países andinos (Benitez, 1987), roedores como a capivara (Hydrochoerus hydrochaeris) nos países amazônicos e pequenos ruminantes e roedores nos países africanos (Malaisse In. CIUF, 1987). Neste contexto, os suínos, alimentados com produtos e subprodutos provenientes da propriedade, com desperdícios de cozinha e de restaurantes, com resíduos de plantações industriais, de fábricas e mesmo das lixeiras das pequenas e grandes cidades, constituem-se na esperança econômica das populações de baixos rendimentos que assentam sua economia na possibilidade de economizar por este mecanismo (Benitez, 1995). Com o propósito de dispor de recursos para satisfazer urgentes necessidades derivadas de suas atividades religiosas, sociais e culturais, os moradores contam com pequenos rebanhos de animais de 1 a 4 matrizes (Alvarado e Gómez, 1982; Benitez, 1995), ou pequenos rebanhos de 2,5 animais em média (Proaño e Chávez, 1998), que são alimentados com os recursos alimentares locais. Quando os excedentes são suficientes, os pequenos produtores mantêm um ou mais animais para engorda, mas a grande maioria das crias é destinada à venda. Os suínos destinados a criação ou engorda são uma fonte de poupança para a família. As fêmeas em gestação, como os animais de acabamento, quando alimentados com milho ou com produtos regionais: banana, tubérculos, cana e outros produtos geralmente pobres em proteínas, tentam satisfazer as suas necessidades nutricionais escavando a terra em busca de raízes, insetos e pequenos animais ricos em proteínas. Os animais entram em engorda quando deixam de ser utilizados como reprodutores e os machos são, geralmente castrados. O ciclo de engorda ou de acabamento pode durar entre dois e quatro meses, dependendo da disponibilidade de alimentos, depois são destinados à venda em feiras ou na unidade de produção até onde chegam os intermediários e compradores. A vida média destes animais ultrapassa largamente um ano de idade e pode chegar aos sete e nove anos, como no caso dos reprodutores que são engordados quando terminam o seu ciclo reprodutivo. Em todo o caso, a poupança, a disponibilidade de gordura e de proteínas são a contribuição substancial para uma família de escassos recursos. ZOONOSES E ANTROPOZOONOSES Embora uma grande variedade de doenças parasitárias, bacterianas, virais, micóticas e até nutricionais possam afetar os porcos, sua curta vida produtiva faz com que estas tenham uma mínima expressão nos ciclos produtivos, principalmente quando são prestados os cuidados necessários. Está provado que os suínos, e outros animais explorados extensivamente, não são atacados por doenças infectocontagiosas como acontece nas explorações intensivas com densidades elevadas. No entanto, estas doenças podem existir, como foi o caso dos suínos ibéricos que sofreram da Peste Suína Africana com graves perdas nos rebanhos e na economia dos produtores. Somente um trabalho organizado e grandes investimentos do Estado permitiram sua erradicação e declarar a Espanha livre dela em 1995. No entanto, existem algumas doenças zoonóticas que merecem a atenção dos criadores para evitar o contágio, entre as quais destaco: 1. Enfermidades bacterianas Tuberculose: Tem como agente etiológico no homem o Mycobacterium tuberculosis, entretanto, algumas outras espécies como M. bovis, M. avium, M. intracelular e M. tuberculose, podem atacar o porco. M. bovis é a causa de até 90% da doença em suínos, produzindo lesões hiperplásicas a nível intestinal, inflamação na região orofaríngea e nos gânglios submaxilares. O contágio ocorre geralmente em contato com pessoas ou bovinos doentes, através de alimentos para animais, de resíduos alimentares de leitaria, de cozinha, de hospitais e de outros produtos contaminados. A vacinação nas áreas endêmicas reduziu a incidência desta doença. Brucelose: É uma doença generalizada em todo o mundo, causada pelas bactérias do gênero Brucella, do qual se conhecem seis espécies e múltiplos biotipos, sendo as mais difundidas: B. abortus, B. melitensis e B. suis, na sua ordem. Os suínos são atacados pela B. suis, principalmente, mas as outras espécies de brucelas podem também produzir a doença. Os animais são infectados no coito. Os sintomas são abortos e baixa fertilidade do rebanho. Os casos de artrite e a presença de nodulações, também podem ser indicadores da doença. Um reconhecimento atempado da doença e o destino adequado dos animais doentes pode evitar a presença de portadores e o contágio. 2 Enfermidades virais Febre aftosa: É uma doença que ataca o porco na sua qualidade de animal biungulado, produzida pelos vírus do genoma ARN, gênero Aphtovirus, com sete tipos: A, O, C; SAT1, SAT2, SAT3 e Ásia 1, facilmente modificáveis. Em todo o mundo, existem áreas que se livraram da doença com a vacinação, controles migratórios e abate de animais, principalmente. Entretanto, uma grande superfície do planeta fica sob observação permanente. A presença de vesículas na cavidade bucal, inflamação ou perda dos cascos e dificuldade ao caminhar, põem em evidência a doença. A introdução de animais contaminados e de produtos à base de carne pode acelerar a disseminação da doença, ao passo que a vacinação da maioria dos animais com a estirpe adequada evita as epizootias. 3. Enfermidades parasitárias Cisticercose: É uma parasitose associada às condições higiênicas e à pobreza, encontra-se em todos os países onde o porco é explorado de maneira tradicional. Os animais são infestados pelo consumo de excrementos de seres humanos contendo os embriões hexacantos da Taenia solium. Estes embriões, também conhecidos como óvulos, ao penetrar no intestino passam por via sanguínea aos diferentes músculos onde continuam seu desenvolvimento embrionário para logo se transformarem em cisticercos. A parasitose é assintomática nos porcos, mas podem-se palpar ou observar nodulações, in vivo, na língua do animal e em algumas ocasiões na pálpebra interna, enquanto que a inspeção, post morten, podem ser observados cisticercos na língua, coração, diafragma, masseteres, glúteos, dorsais e músculo psoas, principalmente. As pessoas adquirem a tênia consumindo carne parasitada na qual os cisticercos estão vivos. A teníase é a causa da terrível parasitose humana, conhecida como neurocisticercose, que é estabelecida como resultado do alojamento de cistos no cérebro humano, derme, epiderme e região ocular. Pode causar graves transtornos patológicos no homem e inclusive a morte. O portador de T. solium se converte no transmissor da neurocisticercose já que as proglotis da tênia adulta, que são expulsos em número de 3 a 7 diariamente, contêm entre 40 e 60 mil filhotes, que, por contato ou contágio de alimentos, podem ser transmitidos às pessoas. Em muitos casos, o fecalismo ao ar livre, ou próximo das vertentes de água, pode causar contaminação de porcos coprofágicos e das culturas, principalmente hortaliças ou outras de sistema radicular e caule curto. Triquinose: A triquinose do porco é produzida por um nematódeo conhecido como Trichinella spiralis. As pessoas são infestadas com carne de porco que contém larvas de triquina. As larvas entram no intestino onde amadurecem rapidamente e se reproduzem para depois, por meio dos vasos linfáticos, chegar aos músculos estriados onde se encapsulam. As larvas alojadas nos músculos lisos geralmente morrem. Os suínos são contaminados pelo consumo de resíduos de alimentos à base de carne contendo triquinas. A emaciação e a dor muscular das extremidades posteriores servem para dificultar o diagnóstico. Segundo Acha e Szyfres (1986), um porco de 100 kg parasitado pode infestar 360 pessoas. Estes autores também sustentam que a parasitose tende a desaparecer no mundo, sendo sua incidência, em muitos países europeus, inferior a 0,1%, e que em países como Brasil, Paraguai, Colômbia, Venezuela e Equador não se detectou esta parasitose. No caso equatoriano, os trabalhos realizados por Ayabaca e Vizuete (1997) confirmam a inexistência da doença no país. CONCLUSÃO A criação de suínos é de extrema importância para o mundo agropecuário. Seja nas criações de pequenos produtores, ou mesmo de grandes produtores, os suínos têm papel importante na obtenção de proteína para a alimentação humana, de emprego para milhões de pessoas, de renda, de produtos diversos, de gordura, de biogás etc. O sistema consorciado da criação de suínos com o meio agrícola é uma criação majoritária e presente em todos os países. Os suínos beneficiam o solo com suas excretas; o homem, por meio delas obtém o biogás necessário para produção de energia, de aquecimento etc. Milhões de camponeses criadores de suínos consorciados com outras culturas animais e vegetais, demonstram a eficiência da modalidade para o mundo contemporâneo e que podem, em muitos casos, obter renda necessária para sustento de suas famílias e da comunidade local. Todavia, vale salientar que os suínos tradicionais são resistentes à inúmeros agentes patogênicos, porém além de serem resistentes, a falta de higiene e profilaxia, além da medicina preventiva, podem ser cruciais para a disseminação da doença e morte total do plantel de animais. Os suínos produzem carne, produzem renda, produzem emprego, produzem a comunhão local, os suínos são animais peculiares, transformadores e contemporâneos. Pense, crie, recrie! (shrink)

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

Die anhaltende Popularität von juristisch geprägter Literatur zeigt, dass das Ringen um die Gerechtigkeit im Recht ein brisantes Thema ist, das gesellschaftliche Aufmerksamkeit auf sich zieht, provoziert und immer wieder neu zum Nachdenken herausfordert. Zeitgenössisch sind es Autor*innen wie Juli Zeh, Bernhard Schlink, Georg Oswald oder Ferdinand von Schirach (sogenannte Dichterjurist*innen 1 ), die die Frage nach Recht und Gerechtigkeit literarisch verbinden und deren Problemkontexte beleuchten. Juli Zeh lässt ihrem Roman Spieltrieb die Erzählerinstanz sprechen: „Das Recht ist kein Kreißsaal für (...) die Gerechtigkeit […]“ (2013, 518). Auch Ferdinand von Schirach bemüht sich herauszustellen, dass für ihn Recht nicht gleich Gerechtigkeit bedeutet. Als Strafverteidiger sagt er über die Justiz: „[W]ir sprechen […] nicht Gerechtigkeit, sondern Recht“ (Heise 2009).3 In seinen Bestsellern (angefangen von z. B. Der Fall Collini über Terror bis zu seinem neusten Stück Gott) provoziert er das Gerechtigkeitsempfinden seiner Leser*innen und lässt sie am Ende gerne selbst das Urteil fällen. In Terror (2016) soll das Publikum als Jury selbst entscheiden, ob der Kampfpilot das entführte Passagierflugzeug, das auf ein voll besetztes Fußballstadion zugesteuert ist, hätte abschießen dürfen. Hier geraten u. a. die Gewissensentscheidung des Piloten und die Rechtsgrundlage in einen Konflikt. Nicht selten macht er den Leser*innen das Recht schwer erträglich, wenn er z. B. wie im Erzählband Schuld (2017) auf brutale Weise beschreibt, wie eine minderjährige Kellnerin auf einem Volksfest von einer Gruppe von Männern vergewaltigt wird, aber aus Beweismangel letztendlich keiner dieser Männer schuldig gesprochen werden kann. In der Literatur werden vielfältige Zugänge zum Verhältnis von Recht und Gerechtigkeit eröffnet – wie kann sich die christliche Sozialethik positionieren? (shrink)

Prof. (Dr.) Balwant Singh Dhillon, a much-acclaimed Sikh-historian, a dedicated researcher, a prolific writer, and a profound scholar of religion, was born in 1950, at Village Ran Singh Wala, District Faridkot, Punjab, India. With his keen interest in learning, he received a B.A. degree from SGGS College, Chandigarh, in 1972, and an M.A. (History) degree from the University of Rajasthan, Jaipur in 1974. During his younger days, he nurtured a keen interest in sports. On attaining the National Level Athlete ranking, (...) he was enthusiastic about pursuing a career in sports. Thereby, he joined Master Course for Coaching in athletics at the National Institute of Sports, Patiala, in 1974. Herein, he came in contact with Prof. Labh Singh of the Institute of Sikh Studies (IOSS, now Gurmat College), who inspired him to take up Sikh studies. This interaction brought a sea change in his life motive, and he committed himself to pursue a career in Sikh studies. After receiving M.A. (Religious Studies) degree from the IOSS in July 1976, he joined M. Lit. (Religious Studies) course at Punjabi University, Patiala. Here he had the opportunity to learn from several eminent scholars, e.g., Prof. Harbans Singh, Prof. Gurbachan Singh Talib, Prof. L.M. Joshi, and Dr. A.N. Sinha, etc., which made his resolve steadfast. In January 1977, he joined the Department of Guru Nanak Studies at Guru Nanak Dev University (GNDU), Amritsar, to pursue his research activities for a Ph.D. degree. In March 1985, he was awarded a Ph. D. degree by GNDU, for his outstanding research work on "The Sikh Gurus and the Mughal State." Starting, in April 1979, as a Research Assistant at the Department of Guru Nanak Studies, he rose to the position of Professor and Head of the department. He retired in June 2010. During his tenure at the university, he had also served as Dean, Faculty of Humanities and Religious Studies, Senator and Syndic of the University. As Head of the Department of Guru Nanak Studies, he played a vital role in starting the teaching of M.A. (Religious Studies and Philosophy)at GNDU, Amritsar. Under his stewardship, the research projects on "Sikh Religion and Philosophy," "Sikh History," and "Sikh Literature" were taken up, which led to a research and development grant of Rs. 3.2 Million from U.G.C., New Delhi, during 2006-2011. Dr. Dhillon was instrumental in establishing the Centre on Studies in Sri Guru Granth Sahib at the university, in April 2011, and served as its founding Director till February 2015. He has also served as the Editor-in-Chief for reputed Sikh research journals, "Journal of Sikh Studies" and "Perspectives on Guru Granth Sahib," published by the GNDU. In his forty years long professional career, he has been credited with authoring/publishing about a dozen books and over 100 articles in various research journals, books, and encyclopedias. Besides chairing several international seminars/conferences, he played a vital role in organizing many such events at the Department of Guru Nanak Studies and Centre on Studies in Guru Granth Sahib. He has the honour of representing India at many conferences/ seminars within Canada, America, England, Germany, and Australia. With his continuous dedication to religious studies, he has established himself as an exponent of interfaith dialogue and an eminent writer in the field of Sikh history. Through his well-researched and analytic writings, he has created an indelible mark of scholarship on his readers' minds. For his outstanding contributions in the fields of Sikh history and literature, he has been honoured by several literary and social organizations. Despite his great love and commitment to Sikh History and Religion, Dr. Dhillon subscribes to the idea that Sikh Gurus' Philosophy is perennial and universal in its approach to understand cosmology, Nature, life, and human behaviour in the present era. Furthermore, He asserts that the Sikh Gurus' ideology, its beliefs and practices, social order, worldview, and devotional pattern, as propounded in Sri Guru Granth Sahib, address the basics befitting the 21st century. His views on various aspects of Sikh history and philosophy are presented here for the benefit of readers. (shrink)

In the wake of the global financial crisis of 2008, the greatest economic disaster since the Great Depression, the cover story of the July 18th 2009 issue of The Economist, entitled “What went wrong with economics,” opened with an unequivocally incriminating statement: “Of all the economic bubbles that have been pricked, few have burst more spectacularly than the reputation of economics itself.” In the months surrounding this indictment, many influential economists, including several Nobel laureates, were drawn to the same embarrassing (...) conclusion. Despite the existence of a handful of Cassandras, economists, as a group, had failed to foresee the crash. This short essay reviews the criticisms addressed to modern economic theory in the immediate aftermath of the crash. Overall, the main issues raised by critics were that (a) economists versed in the dominant models in macroeconomics and finance have been blinded to the possibility that we live in an uncertain and complex world; and (b) that the content of current economics education has sidelined many of the relevant insights to be found in the history of the discipline. This has led the critics to call for changes in the institutional structure of discipline, with a particular emphasis on the promotion of interdisciplinarity, and theoretical and methodological pluralism.

Purpose. The purpose of this study is to investigate how professionals learn from varying experiences with errors in health-care digitalization and develop and use negative knowledge and digital ignorance in efforts to improve digitalized health care. Design/methodology/approach. A two-year qualitative field study was conducted in the context of a public health-care organization working with digital patient communication. The data consisted of participant observation, semistructured interviews and document data. Inductive coding and a theoretically informed generation of themes were applied. Findings. The (...) findings show that both health-care and digital communication professionals learn through experiences with digital “rule-” and “knowledge-based” errors in patient communication and develop negative knowledge and awareness of digital ignorance. In their joint efforts, they use negative knowledge to “bend the rules” and to explore digital ignorance in efforts to improve patient communication. Originality/value. This study provides insight into the importance of collaboration between professionals with varying experience of errors in digitalizing patient communication. Such collaboration is required to acknowledge own shortcomings and create complementary negative knowledge to improve digital patient communication. This is particularly important when working with innovative digitalization in health care. (shrink)

We are developing the Neurological Disease Ontology (ND) to provide a framework to enable representation of aspects of neurological diseases that are relevant to their treatment and study. ND is a representational tool that addresses the need for unambiguous annotation, storage, and retrieval of data associated with the treatment and study of neurological diseases. ND is being developed in compliance with the Open Biomedical Ontology Foundry principles and builds upon the paradigm established by the Ontology for General Medical Science (OGMS) (...) for the representation of entities in the domain of disease and medical practice. Initial applications of ND will include the annotation and analysis of large data sets and patient records for Alzheimer’s disease, multiple sclerosis, and stroke. (shrink)

McDowell and Merleau-Ponty share a critical attitude towards a certain Cartesian picture of the mind. According to the picture in question nothing which properly belongs to subjectivity can be hidden to the subject herself. Nevertheless there is a striking asymmetry in how the two philosophers portray the problematic consequences of such a picture. They can seem to offer exact opposite views of these consequences, which, given the almost identical characterization of the transparency claim, is puzzling. I argue that a closer (...) look at the prima facie puzzling asymmetry dissolves the apparent disagreement and reveals a deeper agreement concerning both the nature and the origin of the problems haunting the Cartesian picture in question. Both McDowell and Merleau-Ponty argue that on the picture of the relation of between mind and world in question, we lose our grip on the very idea of a perceptual appearance. Furthermore, the two authors regard a certain conception of nature as conceived in the image of science, as one of the crucial elements in making the picture of the mind in question look attractive.

This essay centers on the notion of the symbolic and its impact as developed by Claude Lévi-Strauss in his Introduction to the Work of Marcel Mauss. I examine Lévi-Strauss’ formulation of the “floating signifier” and its influence in French thought, particularly in the work of Jacques Lacan and Jacques Derrida. In doing so, I argue that Lévi-Strauss’ notion may be a misreading of the structural linguistics of Ferdinand de Saussure that has important implications for contemporary political issues on the left (...) in both theory and practice.

The Neurological Disease Ontology (ND) is being developed to provide a comprehensive framework for the representation of neurological diseases (Diehl et al., 2013). ND utilizes the model established by the Ontology for General Medical Science (OGMS) for the representation of entities in medicine and disease (Scheuermann et al., 2009). The goal of ND is to include information for each disease concerning its molecular, genetic, and environmental origins, the processes involved in its etiology and realization, as well as its clinical presentation (...) including signs and symptoms.

This essay reads acclaimed poet James Galvin’s 1992 semi-autobiographical novel through the lenses of Martin Heidegger’s notion of authenticity and Patrick Wolfe’s discussion of settler-colonialism. I argue that Lyle, arguably the novel’s main character, is portrayed as living “authentically” in contrast to the deep inauthenticity of Ferris. I connect Western authentic dwelling with settler-colonial logic, centering my account on the figures of the “lazy” and “magical” “Indian.” Ultimately, I find that far from rejecting settler-colonial logic Galvin’s text plays out of (...) a return of the repressed of the present absence of indigenous persons in the land and the text.

Non-epistemic values pervade climate modelling, as is now well documented and widely discussed in the philosophy of climate science. Recently, Parker and Winsberg have drawn attention to what can be termed “epistemic inequality”: this is the risk that climate models might more accurately represent the future climates of the geographical regions prioritised by the values of the modellers. In this paper, we promote value management as a way of overcoming epistemic inequality. We argue that value management can be seriously considered (...) as soon as the value-free ideal and inductive risk arguments commonly used to frame the discussions of value influence in climate science are replaced by alternative social accounts of objectivity. We consider objectivity in Longino's sense as well as strong objectivity in Harding's sense to be relevant options here, because they offer concrete proposals that can guide scientific practice in evaluating and designing so-called multi-model ensembles and, in fine, improve their capacity to quantify and express uncertainty in climate projections.

My aim in this paper is to determine how Locke understands suspension and the role it plays in his view of human liberty. To this end I, 1) discuss the deficiencies of the first edition version of ‘Of Power’ and why Locke needed to include the ability to suspend in the second edition, then 2) analyze Locke’s definitions of the power to suspend with a focus on his use of the terms ‘source’, ‘hinge’, and ‘inlet’ to describe the power. I (...) determine from these descriptions that the ability to suspend is a passive power and is a necessary condition for the rational deliberation that Locke takes to be necessary for acting as a free agent. In 3) I connect Locke’s view of the power to suspend to his discussion in the sections that precede ‘Of Power.’ I argue that the kind of judgment that Locke endorses in his discussion of the Molyneux problem is also at work in acts of suspension. In 4) I apply my interpretation to Locke’s description of the connection between the power to suspend and liberty. In 5) I conclude with a discussion of a passage from the fifth edition of the Essay. Locke adds this passage to address worries raised by Limborch over the course of their correspondence. According to Chappell, it lends evidence to the view that Locke takes suspensions to be caused by undetermined volitions. (shrink)

This essay explores a theory of panoramas put forward by the experimental postwar German novelist and translator Arno Schmidt. Schmidt claims that panoramas were so pervasive in the visual culture of the nineteenth century that they unconsciously influenced writers of the period, so that when they wanted to describe vast landscapes they unthinkingly framed their descriptions by drawing on experience with specific panoramas. He primarily expounds the theory in his longest work of fiction, Zettel’s Traum (1970), translated as Bottom’s Dream (...) (2016), where he supports it with evidence from Edgar Allan Poe and Jules Verne. He also promoted the theory in later interviews, and regarded it not just as part of his fiction but as a significant discovery in its own right. This essay extracts Schmidt’s theory from its fictional context and illustrates how he thought it could be used hermeneutically to uncover submerged panoramas in the works of nineteenth century authors. We conclude by locating the theory as part of the contemporary reception history of panoramas. (shrink)

Today, a major challenge for climate science is to overcome what is called the “usability gap” between the projections derived from climate models and the needs of the end-users. Regional Climate Models (RCMs) are expected to provide usable information concerning a variety of impacts and for a wide range of end-users. It is often assumed that the development of more accurate, more complex RCMs with higher spatial resolution should bring process understanding and better local projections, thus overcoming the usability gap. (...) In this paper, I rather assume that the credibility of climate information should be pursued together with two other criteria of usability, which are salience and legitimacy. Based on the Swiss climate change scenarios, I study the attempts at meeting the needs of end-users and outline the trade-off modellers and users have to face with respect to the cascade of uncertainty. A conclusion of this paper is that the trade-off between salience and credibility sets the conditions under which RCMs can be deemed adequate for the purposes of addressing the needs of end-users and gearing the communication of the projections toward direct use and action.

In Ethics 4, Spinoza argues that “A free man thinks of nothing less than of death, and his wisdom is a meditation on life, not on death” (E4p67). Spinoza’s argument for this claim depends on his view of imagination, reason, and scientia intuitiva and on his notion of conatus. I explicate Spinoza’s view of life in terms of power (potentia) and show that Spinozan death amounts to reconfiguration rather than absolute annihilation. I then show that E4p67 reflects Spinoza’s well-known account (...) of the three kinds of knowing. Thinking of death is quintessentially imaginative and passive. The free person of E4p67 is in contrast a rational person. To reason, and as becomes especially clear E5, to experience scientia intuitiva, moreover is to think of things “without any relation to time, but [rather] sub specie aeternatitis”(E2p44c2) and to experience activity To the extent, then, that we are rational, free, and active, death is a non-issue. Indeed, to the extent that we are able to meditate on life sub specie aeternitatis, we actually experience joy, love (E5p20s, p32c), eternity (Sp23s), and “the greatest satisfaction of the Mind” (E5p27).

In most discussions of moral responsibility, an agent’s moral responsibility for harming or failing to aid is equated with the agent’s being blameworthy for having done wrong. In this paper, I will argue that one can be morally responsible for one’s action even if the action was not wrong, not blameworthy, and not the result of blameworthy deliberation or bad motivation. This makes a difference to how we should relate to each other and ourselves in the aftermath. Some people have (...) blown off their responsibility when they shouldn't have, and others have held themselves responsible – or second and third parties have held them responsible – as if they were wrongdoers and blameworthy when neither is the case.

In a letter to William Molyneux John Locke states that in reviewing his chapter 'Of Power' for the second edition of An Essay Concerning Human Understanding he noticed that he had made one mistake which, now corrected, has put him "into a new view of things" which will clarify his account of human freedom. Locke says the mistake was putting “things for actions” on p.123 of the first edition, a page on which the word 'things' does not appear (The Correspondence (...) of John Locke. E.S. de Beer, ed. (Oxford: Clarendon, 1976), Vol.4, no.1643, 15 July, 1693.) It is the aim of this paper to (1) elucidate where the correction occurs, (2) give an analysis of why the correction is needed, and (3) give an explanation of why Locke believed replacing 'things' with 'actions' was an important change.

Some interesting exceptions notwithstanding, the traditional logic of economic efficiency has long favored hierarchical forms of organization and disfavored democracy in business. What does the balance of arguments look like, however, when values besides efficient revenue production are brought into the picture? The question is not hypothetical: In recent years, an ever increasing number of corporations have developed and adopted socially responsible behaviors, thereby hybridizing aspects of corporate businesses and social organizations. We argue that the joint pursuit of financial and (...) social objectives warrants significant rethinking of organizational democracy’s merits compared both to hierarchy and to non-democratic alternatives to hierarchy. In making this argument, we draw on an extensive literature review to document the relative lack of substantive discussion of organizational democracy since 1960. And we draw lessons from political theory, suggesting that the success of political democracy in integrating diverse values offers some grounds for asserting parallel virtues in the business case.

I argue that we find the articulation of a problem concerning bodily agency in the early works of the Merleau-Ponty which he explicates as analogous to what he explicitly calls the problem of perception. The problem of perception is the problem of seeing how we can have the object given in person through it perspectival appearances. The problem concerning bodily agency is the problem of seeing how our bodily movements can be the direct manifestation of a person’s intentions in the (...) world. In both cases what, according to Merleau-Ponty, obscures a recognition of the phenomenon in question is a conception of our bodily capacities, i.e. our sensibility and our motility, which reduces these to the workings of mechanisms that are blind to meaning. I argue that both the problem concerning perception and the problem concerning bodily agency can be properly called transcendental. The problem of perception is transcendental because it concerns the very intelligibility of appearances and judgements with empirical content. The problem of bodily agency is transcendental in the sense that it concerns the very intelligibility of our bodily capacity to carry out intentions and by implication the intelligibility of our intentions as such.

Mental and behavioral disorders represent a significant portion of the public health burden in all countries. The human cost of these disorders is immense, yet treatment options for sufferers are currently limited, with many patients failing to respond sufficiently to available interventions and drugs. High quality ontologies facilitate data aggregation and comparison across different disciplines, and may therefore speed up the translation of primary research into novel therapeutics. Realism-based ontologies describe entities in reality and the relationships between them in such (...) a way that – once formulated in a suitable formal language – the ontologies can be used for sophisticated automated reasoning applications. Reference ontologies can be applied across different contexts in which different, and often mutually incompatible, domain-specific vocabularies have traditionally been used. In this contribution we describe the Mental Functioning Ontology (MF) and Mental Disease Ontology (MD), two realism-based ontologies currently under development for the description of humanmental functioning and disease. We describe the structure and upper levels of the ontologies and preliminary application scenarios, and identify some open questions. (shrink)

Since the mid-1990s, there has been a rise in the number of deaths of undocumented Mexican migrants crossing the U.S./Mexican border. Who is responsible for these deaths? This article examines the culpability of (1) migrants, (2) humanitarian volunteers, (3) the Mexican government, (4) the U.S. government, and (5) U.S. businesses. A significant portion of the blame is assigned to U.S. free trade policies and U.S. businesses employing undocumented immigrants.

This is an overview of Davidson's theory of anomalous monism. Objections and replies are also detailed.

Assessments of an action done intentionally, as we might expect, influence judgments of moral responsibility. What we don't expect is the converse--judgments of moral responsibility influencing assessments of whether an action was done intentionally. Yet this is precisely how people decide, according to Knobe (2003, 2004) and Mendlow (2004) and Nadelhoffer (2004a). I evaluate whether the studies actually support this biasing effect. I argue that the studies are at best inconclusive and that even if they demonstrated that people fall under (...) the biasing effect, such tendencies ought to have no bearing upon philosophical analyses of the concept of intentional action.

One of the driving questions in philosophy of mind is whether a person can be understood in purely physical terms. In this presentation, I wish to continue the project initiated by Donald Davidson, whose subtle position on this question has left many more perplexed than enlightened. The main reason for this perplexity is Davidson’s rather obscure pronouncements about the normativity of intentionality and its role in supporting psychophysical anomalism – the claim that there are no laws bridging our intentional states (...) with states of our brain. Insofar as Davidson’s thesis is an ontological one – about the existence of laws or otherwise modally significant connections between the mental and the physical – I think his critics are correct: Davidson has not provided us with a successful argument for psychophysical anomalism. There is, however, a different argument, also based upon considerations about the normativity of intentionality that lead to an equally important conclusion. The conclusion is not ontological but rather epistemic: if thoughts do indeed display normativity, it is hard to understand how they would arise out of mere mechanical occurrences in the brain. To borrow a well-worn phrase, there is an “explanatory gap” between the mental and the physical. Originally coined to capture the epistemic darkness we confront in our attempt to understand phenomenal experiences in purely physical terms, the idea has yet to be explored in the area of contentful mental states or intentionality in general. My argument shall be this: considerations about the normativity of intentionality demonstrate that there is an explanatory gap between the intentional and the physical. In fact, if there were laws of the kind Davidson denies, then the world be more mysterious than if no such laws existed. The presence of an explanatory gap explains why this is so. (shrink)

Non-reductive physicalism is committed to two theses: first, that mental properties are ontologically autonomous, and second, that physicalism is true. Jaegwon Kim has argued that this view is unstable – to honor one thesis, one must abandon the other. In this paper, I present an account of property realization that addresses Kim’s criticism and that explains how the two theses are indeed comfortably compatible.

Davidson has been instrumental in dampening the prospect of reductively explaining the mind. The core of his arguments turn upon his insistence that contentful mental states, the bread and butter of folk psychology, have a “normative element.” In spite of its pivotal role, as well as its intrinsic interest, the concept is very poorly developed and understood. This paper attempts to discern four different strands of the normativity of intentionality and to spark a long overdue systematic examination of a fascinating (...) and significant thesis. (shrink)

We have begun work on two separate but related ontologies for the study of neurological diseases. The first, the Neurological Disease Ontology (ND), is intended to provide a set of controlled, logically connected classes to describe the range of neurological diseases and their associated signs and symptoms, assessments, diagnoses, and interventions that are encountered in the course of clinical practice. ND is built as an extension of the Ontology for General Medical Sciences — a high-level candidate OBO Foundry ontology that (...) provides a set of general classes that can be used to describe general aspects of medical science. ND is being built with classes utilizing both textual and axiomatized definitions that describe and formalize the relations between instances of other classes within the ontology itself as well as to external ontologies such as the Gene Ontology, Cell Ontology, Protein Ontology, and Chemical Entities of Biological Interest. In addition, references to similar or associated terms in external ontologies, vocabularies and terminologies are included when possible. Initial work on ND is focused on the areas of Alzheimer’s and other diseases associated with dementia, multiple sclerosis, and stroke and cerebrovascular disease. Extensions to additional groups of neurological diseases are planned. The second ontology, the Neuro-Psychological Testing Ontology (NPT), is intended to provide a set of classes for the annotation of neuropsychological testing data. The intention of this ontology is to allow for the integration of results from a variety of neuropsychological tests that assay similar measures of cognitive functioning. Neuro-psychological testing is an important component in developing the clinical picture used in the diagnosis of patients with a range of neurological diseases, such as Alzheimer’s disease and multiple sclerosis, and following stroke or traumatic brain injury. NPT is being developed as an extension to the Ontology for Biomedical Investigations. (shrink)

When it comes to the notion of creativity, both R. Dawkins and D. Dennett argue that creativity is a matter of random mutation, in the same way that genes randomly mutate. Neither Dennett nor Dawkins see anything else in the mimetic theory of creativity than a process of Darwinian evolution. However, this complete reliance upon the extension of evolution for understanding creativity needs to be supplemented by combining it with other ideas such as those of "schema theory," because creativity always (...) occurs within a structured context and is not simply a matter of random mutation of ideas. Schema theory comes largely from the works of E.H Gombrich, who argued that "schemas" play a crucial role in how it is that we are able to be creative. He defines schemas as structure and traditions in society that help to convey the meaning of our creative efforts. Just as semantics needs syntax within language in order to formulate and convey meaning, so by analogy memes need schemas for the creation and expression of new ideas. Rather than being the antithesis of creativity, existing forms of expression and traditions are important for the creation of new ideas. This needs to be factored into any theory of creativity in order to account for the effect of the social context on creative endeavours in addition to a Darwinian account of memes. The unconscious processes at work within the brain that are involved in the generation of ideas and other creative products can be understood using the notion of a "generator", as originally conceived by D. Dennett. This notion goes beyond mere concrete Skinnerian behavioural trial and error. Within this generator, there appear to be at work processes such as those of bisociation and association, as discussed by A. Koestler, as well as processes such as the role of language, memory, generate-and-test and intentionality that must be acknowledged in addition to the syntactic operations of schemas and the replicating contents of memes. The operation of all of these ingredients within the generator, when understood together, can be seen as responsible for our ability to be creative. (shrink)

For most people using an advertising slogan as the title for a philosophical paper is going to seem, at best, provocative, and at worst, simply cynical. However, this kind of cynical provocation is precisely what I want to address. That is, Marks and Spencer's tagline 'exclusively for everyone' is an affront to rational thought, but this is also the motive for its effectiveness. Rather than simply stating what's on offer, it plays to our dreams; rather than simply offering to match (...) our expectations, it promises to exceed them. (shrink)
