In this piece, I argue that we Homo sapiens have an ethical duty to restore natural darkness to biodiverse, forested ecosystems. Historically, human beings have relied on forests for material sustenance and psychophysiological wellbeing. Utilizing the philosophical concepts of wildness and relational value, I argue that we are thereby bound by reciprocity to (in return) mitigate forestadjacent light pollution. After all, a variety of forest-dwelling species are negatively impacted by dwindling natural darkness, including (but not limited to): insectivorous and frugivorous (...) bats, various plant (including tree) species, fungi, and a variety of nocturnal pollinators. In addition, the loss of natural darkness precludes human subjects from undergoing a variety of transformative experiences that are uniquely associated with immersion in dark, biodiverse forests. Finally, as oldgrowth groves disproportionately sequester carbon and are negatively impacted by light pollution, increasing artificial light at night indirectly (and worryingly) serves as a driver of global climate change.

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

This book presents Robert S. Hartman’s formal theory of value and critically examines many other twentieth century value theorists in its light, including A.J. Ayer, Kurt Baier, Brand Blanshard, Paul Edwards, Albert Einstein, William K. Frankena, R.M. Hare, Nicolai Hartmann, Martin Heidegger, G.E. Moore, P.H. Nowell-Smith, Jose Ortega y Gasset, Charles Stevenson, Paul W. Taylor, Stephen E. Toulmin, and J.O. Urmson.

In Science Without Numbers (1980), Hartry Field defends a theory of quantity that, he claims, is able to provide both i) an intrinsic explanation of the structure of space, spacetime, and other quantitative properties, and ii) an intrinsic explanation of why certain numerical representations of quantities (distances, lengths, mass, temperature, etc.) are appropriate or acceptable while others are not. But several philosophers have argued otherwise. In this paper I focus on arguments from Ellis and Milne to the effect that (...) one cannot provide an account of quantity in ''purely intrinsic'' terms. I show, first, that these arguments are confused. Second, I show that Field's treatment of quantity can provide an intrinsic explanation of the structure of quantitative properties; what it cannot do is provide an intrinsic explanation of why certain numerical representations are more appropriate than others. Third, I show that one could provide an intrinsic explanation of this sort if one modified Field's account in certain ways. (shrink)

The aim of my paper is to describe and evaluate different conceptions of holism in Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. I distinguish three readings of holistic elements in this work: i) Minimal Holism (E. Anscombe, M. Black, D. Pears); ii) Moderate Holism (J. Conant, C. Diamond, G. Ryle); and iii) Radical Holism (G. Bar-Elli, M. Kremer, P. Livingston). The conclusion is that the most viable option is Moderate Holism since it embraces the logico-syntactical notion of use, rejects an anachronistic interpretation of (...) Tractatarian ontology and allows us to see that the holistic elements are complementary to the initial atomism of the work. Moreover, I point to the consequences of the topic for the overall reading of Wittgenstein’s early and late work. (shrink)

INTRODUÇÃO O anestro pós-parto é o período após o parto no qual a fêmea não apresenta ciclos estrais (atividade cíclica). Na vaca leiteira, o parto é seguido de um período de inatividade ovariana de duração variável, que é principalmente afetada pelo estado nutricional, produção leiteira, ganho ou perda de condição corporal antes e depois do parto, e por condições patológicas como hipoplasia dos ovários, cistos ovarianos, mumificação uterina, piometra entre outras, além, também, de condições ambientais como instalações que podem causar (...) estresse etc. 1. Controle neuroendócrino do anestro Entre os 12 e 15 dias pós-parto, as células gonadotróficas presentes na adenohipófise começam a produzir e secretar o FSH (hormônio folículo estimulante), o qual estimula a primeira onda folicular; entretanto, nenhum folículo dominante do(s) ovário(s) chega a completar seu desenvolvimento devido à carência de estímulo apropriado do LH (hormônio luteinizante) que também é produzido pelas mesmas células e que deve estar presente em altas concentrações. Nas 2 primeiras semanas pós-parto (primeiros 15 dias), as concentrações circulantes de LH são baixas, o que se deve à ausência de reservas do LH e à incapacidade temporal da hipófise para responder ao estímulo da GnRH (hormônio liberador de gonadotrofina). Entre os dias 15 e 20 pós-parto, a hipófise aumenta a sua capacidade para responder ao GnRH; entretanto, o estabelecimento do padrão de secreção do LH adequado para estimular a maturação e a ovulação do folículo dominante das primeiras ondas foliculares depende fundamentalmente do balanço energético. 2. Fatores que determinam o início da atividade ovariana pós-parto Na vaca leiteira, é frequente que algum dos primeiros folículos dominantes que se desenvolvem durante as primeiras duas ou três semanas complete a sua maturação e chegue à ovulação, isto é, madure e ovule. O fator limitante para o reinício da atividade ovariana é o balanço energético negativo (BEN). No gado leiteiro, o consumo de matéria seca (CMS), após o parto, deverá ser aumentado em até quatro vezes, para cobrir a demanda de nutrientes para a produção de leite e mantença; no entanto, a vaca é incapaz de consumir a exigência de matéria seca, por isso recorre a suas reservas de gordura e proteína, e cai em BEN. As vacas que consomem menos matéria seca, produzem menos leite, têm um BEN mais profundo e o período do parto à primeira ovulação é maior. O nível mais baixo do BEN é alcançado entre os 10 a 20 dias pós-parto e a vaca continua em BEN até os 70 a 80 dias pós-parto e, em alguns casos, até aos 100 dias pós-parto (vacas primíparas). Entretanto, mesmo com BEN, uma proporção elevada das vacas inicia sua atividade ovariana normal nas primeiras 8 semanas pós-parto. As vacas que alcançam um nível baixo de BEN rapidamente e saem deste ponto mínimo de forma rápida, iniciam sua atividade ovariana mais rápido também (20 a 30 dias pós-parto) do que aquelas que têm um BEN mais profundo e duradouro, essas muitas vezes permanecem em anestro aos 70 dias pós-parto (figura 1). As mudanças na condição corporal estão correlacionadas positivamente com as concentrações séricas de insulina, IGF-I e leptina; assim, a maior qualificação da condição corporal é maior mediante a concentração sérica desses hormônios, que atuam principalmente como sinais que chegam ao hipotálamo e modificam a frequência de secreção do GnRH e, consequentemente, de LH. A leptina é um hormônio que é produzido pelos adipócitos e tem sido proposto que sua concentração é o sinal mais importante de alterações de condição corporal. A transição do anestro para a ciclicidade coincide com um aumento das concentrações séricas de insulina, IGF-I e leptina. Além das mensagens dadas pelos hormônios supracitados, outras substâncias presentes no sangue fornecem informações sobre o estado metabólico do animal. Por exemplo, os ácidos graxos não esterificados e o β-hidroxibutirato são indicadores da mobilização e utilização da gordura corporal; assim, o aumento destas substâncias proporciona uma mensagem inibidora de reprodução. O intervalo médio entre o parto e a primeira ovulação, em vacas leiteiras em sistemas de produção não intensiva, é em torno de 30 dias; enquanto em vacas em sistemas de produção intensiva, é de 40 dias. Deve-se sinalar que é comum aos 70 dias pós-parto, que 20% das vacas ainda não ovulem. Verifica-se frequentemente que as vacas leiteiras desenvolvem folículos que crescem mais que os folículos ovulatórios, os quais convertem em cistos foliculares. Esta condição está associada com insensibilidade do hipotálamo ao retorno positivo do estradiol, o que não desencadeia o pico pré-ovulatório de LH (figura 2). 3. O corpo lúteo dos primeiros ciclos pós-parto Durante um ciclo estral o corpo lúteo tem uma meia-vida fisiológica de 12 a 14 dias; no entanto, na primeira ovulação pós-parto cerca de 25% das vacas desenvolvem corpos lúteos de vida curta (<10 dias), 30% de vida longa (21 a 50 dias) e 45% da vida normal (11 a 20 dias). A regressão prematura do corpo lúteo é uma condição frequente nos ruminantes no primeiro ciclo estral, da transição do anestro à ciclicidade. Ou seja, na vaca é frequente que no primeiro ciclo de pós-parto e da puberdade sejam ciclos curtos; isto deve-se à liberação antecipada da PGF2α. Por outro lado, a causa dos corpos lúteos de vida longa (corpos lúteos persistentes) não é clara, mas está relacionada com alterações na secreção da PGF2α devido a infecções uterinas (tabela 1). 4. Anestro patológico 4.1 Alterações do aparelho genital que causam anestro Na vaca foi calculado que as alterações do aparelho genital que afetam a atividade ovariana representam apenas 10% do total das causas de anestro. Entre as alterações do aparelho genital se encontram os cistos foliculares, cistos luteinizados, aplasia segmentar, piometra e mumificação fetal. . 4.2 Cistos foliculares Os cistos foliculares são a patologia ovariana mais comum nos bovinos leiteiros, causando perdas econômicas devido ao atraso do período do parto ao primeiro serviço, pelo custo dos tratamentos e pelo risco que têm as vacas de serem descartadas. A incidência aumentou à medida que a produção de leite se intensificou. Entre 5 e 30% das vacas desenvolvem cistos foliculares nos primeiros 60 dias do pós-parto; no entanto, cerca de 60% destas se recuperam espontaneamente. Sinais clínicos de vacas com cistos foliculares descritos na literatura são: ninfomania, ciclos curtos, masculinização e relaxamento dos ligamentos pélvicos. Atualmente uma alta proporção de vacas com cistos foliculares apresentam anestro. Por muitos anos um cisto folicular foi definido como um folículo com um diâmetro de 2,5 mm, presente em um ou em ambos os ovários durante um período mínimo de 10 dias, na ausência de um corpo lúteo. Os conhecimentos atuais modificaram o conceito clássico; assim, nem todos os cistos foliculares têm um diâmetro de 2,5 mm; além disso, alguns podem persistir mais de 10 dias. Outros são estruturas dinâmicas, que sofrem regressão e podem ser substituídas por novos cistos. Por esta razão, a definição mais precisa e técnica de um cisto folicular é: folículo de um diâmetro, de pelo menos 20 mm, que está presente em um ou ambos os ovários na ausência de tecido lúteo que interfere com o ciclo estral normal (figura 3). A patogênese dos cistos foliculares não é conhecida. Propõe-se que as vacas que desenvolvem esta patologia têm uma anomalia nos mecanismos de retroalimentação entre o hipotálamo e a hipófise, em conjunto com uma disfunção a nível folicular. É pesquisado e sugerido que em vacas com cistos foliculares, o pico pré-ovulatório de LH não ocorre ou é de menor amplitude, ou não tem uma relação síncrona com o amadurecimento do folículo, o que provoca a falha ovulatória. A alteração na secreção de LH pode obedecer a falta de sensibilidade do hipotálamo ao feedback positivo de estrogênio. Observa-se também que algumas anormalidades a nível folicular, tais como alterações na síntese de hormônios esteroides e uma menor sensibilidade à LH, podem contribuir com a patogenia. Uma vez que o cisto folicular foi estabelecido, observou-se um aumento na frequência de secreção pulsátil de LH, o que contribui com a persistência desta patologia. Existem fatores associados com a incidência de cistos foliculares que, de acordo com a patogenia proposta, podem influenciar ao nível do eixo hipotálamo-hipófise-ovário. Os cistos foliculares ocorrem principalmente durante a transição do anestro pós-parto para a ciclicidade. Neste período as vacas estão em BEN, e tem sido observado que as vacas que sofrem de um BEN mais profundo tendem a apresentar uma incidência maior de cistos foliculares. Por outra parte, há uma correlação positiva entre a produção de leite e a incidência de cistos, o que indica que as vacas que produzem mais leite têm maior risco de sofrer com esta patologia. Também existem outros fatores relacionados com a incidência de cistos foliculares tais como estresse, genéticos, infecções uterinas, estresse calórico e presença de fitoestrogênios na dieta (tabela 2). O tratamento indicado consiste na administração do GnRH, que provoca a luteinização do cisto. É recomendável a combinação com uma dose luteolítica de PGF2α, 7 a 10 dias depois da injeção de GnRH. Também é indicado o tratamento com hCG em vez de GnRH. Em alguns estudos foi possível integrar vacas com cistos foliculares em programas de sincronização da ovulação e inseminação em tempo fixo, com resultados aceitáveis de fertilidade (figura 4). 4.3 Cistos luteinizados Esse tipo de cisto pode se desenvolver a partir de um cisto folicular, também ocorre quando o saco libera um óvulo e, em seguida, se fecha novamente e enche-se de líquido. O tecido luteinizado produz progestágenos do qual os sinais incluem anestro persistente. São bastante mais raros e originam-se pelo contínuo aumento do espaço cavitário central normalmente existente nos corpos lúteos (figura 5). Normalmente, a parede do cisto contém células lúteogranulosas grandes e células tecaluteais pequenas. Se diferenciam com dificuldade de corpos lúteos recém-formados durante o período em que ainda possuem um antro. Os cistos luteínicos únicos, pelo menos os menores, necessitam de importância clínica. Se os cistos são funcionais, a sintomatologia mais destacada é o anestro ou pseudogestação. É preciso lembrar que esses cistos agem como uma fonte de secreção contínua de progesterona, diminuindo assim a resistência do útero a infecções, podendo desencadear-se uma endometrite (figura 6). Se eles forem diagnosticados é recomendável a administração de PGF2α. 4.4 Aplasia segmentar As vacas com esta condição podem gestar quando a ovulação ocorre do lado do corno uterino presente. Se a ovulação acontece do lado onde falta o corno uterino causa anestro. 4.5 Piometra A piometra, por definição, é a acumulação de material purulento no interior da luz uterina que ocorrem geralmente durante ou imediatamente após o período de domínio da progesterona. É uma condição que ocorre mais frequentemente nos primeiros 30 dias pós-parto; no entanto, algumas vacas em anestro que são revisadas no dia 50 pós-parto chegam a ter piometra. O tratamento indicado consiste na administração de PGF2α. 5. Anestro relacionado com o tempo de serviço O anestro em bovinos também é classificado como anestro pré-serviço e pós-serviço. 5.1 Anestro pré-serviço Inclui vacas e novilhas que não tenham mostrado estro, isto é, manifestado cio, no período em que devem ser servidas. Em alguns estudos observou-se que o anestro antes do serviço pode afetar até 50% das vacas elegíveis para apresentar estro. 5.1 Anestro pós-serviço Neste grupo incluem-se as vacas que não retornam ao estro, ou seja, que não retornaram ao cio, 21 dias depois da inseminação e não estão prenhes. Essas vacas são conhecidas como vacas fantasma (The Phantom Cow). A causa principal do atraso do retorno ao estro é a baixa eficiência na detecção de estros; mas também foram descritas outras causas como: inseminação em um estro anovulatório, inseminação em tempo fixo em vacas em anestro, suspensão da ciclicidade após o serviço, fases lúteas longas e morte embrionária. O diagnóstico precoce da gestação é de grande ajuda para conhecer oportunamente o número de fêmeas que não estão prenhes. A ecografia no trigésimo dia pós-inseminação adianta, pelo menos 10 dias, a ressincronização de vacas vazias. 6. Falso anestro ou anestro funcional Este causa as maiores perdas econômicas de caráter reprodutivo em rebanhos leiteiros, e refere-se às vacas que estão ciclando, mas não são observadas em estro pelos trabalhadores. É um dos maiores problemas dentro de um sistema de criação extensivo e, às vezes, semiintensivo, uma vez que é de suma importância a observação técnica e precisa do comportamento da vaca para observar o possível retorno ao cio ou não. 7. Manejo da vaca anéstrica A probabilidade de que a vaca seja inseminada oportunamente depende da eficiência da detecção de estros. É comum que a metade das vacas apresentem estro e não sejam observadas, por essa razão, muitas não são inseminadas uma vez que termina o período de espera voluntária. Por outro lado, há vacas que, por causas patológicas ou por seu estado metabólico, ainda estão em anestro depois que termina o período voluntário de espera. Para identificar as causas da ausência de estros, todas as vacas que não tenham sido inseminadas no dia 60 pós-parto, devem ser revisadas por via retal para aplicar o tratamento ou manejo pertinentes. Durante esta revisão é dada especial atenção às características do útero e nas estruturas ovarianas, já que daqui depende o manejo subsequente. A palpação começa no útero; neste é importante determinar se não há gestação. Posteriormente, avalia-se sua consistência que pode ser normal, edematosa ou turgente. Depois de avaliar o útero procede-se a palpação dos ovários, começando com o direito e, em seguida, esquerdo. Abaixo estão descritas as diferentes descobertas que podem ser encontradas na literatura e seu tratamento ou manejo. O registo dos resultados à palpação é feito através de chaves reprodutivas. 7.1 UN CLD2-3 FE10 Útero normal (UN) com um corpo lúteo 2 ou 3 no ovário direito (CLD2-3) e um folículo no ovário esquerdo de 10 mm de diâmetro (FE10). A consistência normal do útero (é normal quando não há edema ou turgescência) é encontrado em vacas não prenhes durante o diestro, ou em vacas que estão em anestro. O CL 2 ou 3 é uma estrutura bem desenvolvida que deforma o ovário e em alguns casos representa mais de 50% da massa ovariana. Classificá-los como CL 2 ou 3 é uma apreciação subjetiva do tamanho do corpo lúteo e não tem significado prático, pois em qualquer dos casos o manejo é o mesmo. O CL indica que a vaca está em qualquer dia do diestro e, obviamente, indica que está ciclando. Durante o diestro pode-se encontrar folículos de tamanho diferente em qualquer um dos dois ovários, já que este depende das ondas de desenvolvimento folicular. É importante frisar que as estruturas mencionadas podem estar em ovários diferentes ou no mesmo ovário. O achado mais importante nesta fase é a presença do corpo lúteo o que permite o tratamento com a PGF2α, o que resulta na apresentação do estro nas próximas 48 a 120 horas. A presença de um corpo lúteo é o estado fisiológico que é mais frequentemente encontrado neste grupo de vacas, primeiro porque paradoxalmente a maior proporção de vacas em “anestro” está ciclando (anestro funcional) e, em segundo lugar, porque o diestro ocupa 65% dos dias do ciclo estral. 7.2 UE CLD1 FE10-15 Útero edematoso (UE) com um corpo lúteo 1 no ovário direito (CLD1) e um folículo 10 ou 15 mm de diâmetro no ovário esquerdo. O útero edematoso pode ser encontrado no proestro e metaestro. A presença do CL1 e um folículo grande indica que se trata de uma vaca que muito provavelmente é encontrado em proestro. A diferença entre um CL1 e um CL 2 ou 3 é basicamente o seu tamanho; um CL1 é uma estrutura pequena com consistência dura. As vacas que têm estas características devem ser marcadas para que os trabalhadores prestem mais atenção, já que apresentarão o estro nas próximas 48 a 72 horas. Se a vaca não apresentar estro nesse período, deverá ser palpada na semana seguinte. 7.3 UT DE FE10-15 Útero túrgido ou tonificado, ovário direito estático e ovário esquerdo com um folículo de 10 ou 15 mm de diâmetro. Estes achados, além da presença de muco estral, correspondem a uma vaca em estro. Frequentemente, na palpação das vacas do grupo de anestro, há vacas em estro; estas vacas deverão ser programadas para inseminação. 7.4 UE DE EE Útero estático e ovários estáticos. Estas observações correspondem a uma vaca em metaestro; esta decisão tem uma alta margem de erro uma vez que também pode corresponder a um animal no proestro ou em anestro verdadeiro. Um achado que permite ser mais bem sucedido no diagnóstico é a presença de sangue no muco cervical; neste caso, a presença de sangue indica, com certeza, que a vaca está em metaestro; no entanto, nem todas as vacas apresentam este sangramento. As vacas com estes achados devem ser palpadas sete dias depois para confirmar ou corrigir um primeiro diagnóstico. Se a primeira palpação foi correta, na segunda se encontrará um CL2-3. 7.5 UE CHD FE10 Útero edematoso, com corpo hemorrágico no ovário direito (CHD) e com folículo de 10 mm de diâmetro no ovário esquerdo. Estas observações são de uma vaca em metaestro. O corpo hemorrágico é considerado como a fase de transição entre o folículo e o corpo lúteo; o CH é palpado como uma estrutura com uma saliência em forma de papila e é muito suave ao toque. Será necessário esperar 4 ou 5 dias para que se converta num corpo lúteo maduro e assim destruí-lo com PGF2α. Na rotina, estas vacas são palpadas na seguinte revisão (sete dias depois). 7.6 UN DE EE Útero normal e ovários estáticos. Este caracteriza as vacas que estão no anestro verdadeiro. As vacas caem no anestro principalmente por se encontrar em balanço negativo de energia; este problema é mais grave em vacas de primeiro parto. O único tratamento eficaz consiste em melhorar o seu estado metabólico. Tratamentos hormonais não funcionam caso não seja resolvido primeiro o seu estado nutricional. 7.7 UN CFD EE Útero normal, cisto folicular no ovário direito e ovário esquerdo estático. Embora as vacas com cistos foliculares sejam caracterizadas por apresentar estros recorrentes, também chegam a apresentar anestro. O tratamento consiste na administração do GnRH ou hCG. 7.8 UN CLD EE Útero normal, cisto luteinizado no ovário direito e ovário esquerdo estático. Este cisto também é causado por uma deficiência na secreção de LH, só que neste caso a deficiência foi parcial, o que provoca um certo grau de luteinização. O cisto luteinizado é uma estrutura com mais de 20 mm de diâmetro de paredes grossas. O tratamento indicado é a administração de PGF2α. Na prática, é difícil diferenciar um cisto folicular de um luteinizado, pelo que o tratamento recomendado é, primeiro, a administração de GnRH ou hCG e sete dias depois é injetado PGF2α (figura 7). 7.9 Piometra CLD2-3 FE A piometra é uma condição que ocorre principalmente nos primeiros 30 dias pós-parto; no entanto, na revisão das vacas anéstricas são encontradas vacas com esta patologia. O tratamento indicado consiste na administração de PGF2α. 8. Tratamentos hormonais para indução da atividade ovariana O estabelecimento precoce da ciclicidade pós-parto favorece a involução uterina e está positivamente correlacionado com a fertilidade; ou seja, quanto mais ciclos estrais a vaca tenha antes da primeira inseminação, a percentagem de concepção é maior. Um tratamento utilizado para induzir a primeira ovulação pós-parto em vacas anéstricas, consiste na administração de GnRH quando à palpação retal se encontra um folículo grande (> 10 mm). Com isso se pretende fazer o folículo ovular e depois injeta-se PGF2α para provocar a regressão lútea. Outras combinações consistem na administração de GnRH e na inserção de dispositivos de liberação de progesterona e, ao retirar o progestágeno, injeta-se PGF2α (figura 8). No entanto, os tratamentos mencionados são de uso comum, não funcionam em todos os casos. Um requisito para se obter êxito é que as vacas devem ter boa condição corporal ou que estejam ganhando condição corporal. Embora os tratamentos hormonais possam ajudar em alguns casos, não deve-se esquecer que as causas do anestro não são corrigidos apenas com a administração de hormônios, já que a vaca não cicla porque toda a informação do estado metabólico que recebe o cérebro, indica que não o deve fazer. 9. Gonadotropina coriônica equina (eCG) Na égua, por volta do dia 30 de gestação, células do córion migram para o endométrio e formam umas estruturas conhecidas como copas endometriais. Entre o dia 40 e o dia 130 de gestação nestas estruturas é produzido o eCG (anteriormente conhecida como gonadotropina sérica da égua prenha ou PMSG, pela sua abreviatura em inglês). Na égua esse hormônio tem atividade de LH pelo qual estimula a função do corpo lúteo e promove a formação de corpos lúteos acessórios. Nos ruminantes, o eCG se une aos receptores de LH e FSH do folículo, estimulando o desenvolvimento folicular, e no corpo lúteo estimula a secreção de progesterona. O eCG tem sido utilizado com a finalidade de superovulação e em vacas de corte sob anestro é incluído em programas com progestágenos para induzir ciclicidade. Nestes programas é injetado eCG no momento da remoção do progestágeno, o que favorece o desenvolvimento folicular e apresentação do estro. Em rebanhos leiteiros na Nova Zelândia tem sido incrementado a taxa de prenhez sem aumentar a proporção de partos gêmeos, através da injeção de eCG na remoção do dispositivo de libertação de progesterona em programas combinados com a injeção de benzoato de estradiol. RESUMO ➢ Transcorrem 15 dias pós-parto para que a hipófase responda ao hormônio GnRH. ➢ Entre os dias 12 e 15 pós-parto começa-se a secreção de FSH e iniciam as ondas foliculares. ➢ As vacas chegam ao ponto mais baixo de BEN entre os dias 15 e 20 pós-parto. ➢ As vacas iniciam a atividade ovariana normal, em média, após os 40 dias pós-parto. ➢ Aos 70 dias pós-parto é normal que 20% das vacas ainda estejam em anestro. ➢ Na primeira ovulação pós-parto 25% das vacas desenvolvem corpos lúteos de vida curta e 30% mostram corpos lúteos de vida longa (persistentes). ➢ As anormalidades do aparelho reprodutor são responsáveis por 10% das causas de anestro. ➢ 5 a 30% das vacas desenvolvem cistos foliculares nos primeiros 60 dias pós-parto e 60% destas se recuperam de forma espontânea. ➢ No dia 30 pós-inseminação é possível identificar vacas vazias mediante a ecografia e reservá-las para a ressincronização. ➢ A proteína B específica da gestação aparece no soro a partir do 15º dia de gestação. ➢ Para o diagnóstico precoce de gestação é recomendado medir a PSPB no dia 30 pósinseminação e em vacas com mais de 90 dias pós-parto. ➢ Entre os dias 50 e 60 pós-parto todas as vacas não servidas devem ser examinadas via retal para programar seu serviço.

ABSTRACT Approaching Cognitive-Behavioral and Existential Therapy Through Neo-Confucianism (December 1984). Joffre Denis Meyer, B. A. Texas A&M University Chairman of Graduate Committee: Dr. William R. Nash -/- The thesis is an effort to bring Neo-Confucian insights to modern cognitive- behavioral and existential therapy. The adaptability of Neo-Confucianism is illustrated through the growth-system inherent in its concepts. Frequently, Neo-Confucian sages and modern psychologists used virtually identical statements. Moreover, humanity faces the same basic issues while the particularizations vary. The importance of reason, (...) manners, appropriate behavior and self-actualization remains constant. However, the methods of their attainment change with time. The history of the Confucian/Neo-Confucian tradition is filled with such conceptual modifications. -/- Neo-Confucianism is a syncretic philosophy that utilized elements of Zen, Taoism, and Legalism within Confucian teachings. This adaptation increased the sages' ability to communicate with a wider range of people. In effect, the Neo-Confucian movement was perhaps the earliest practice of eclectic counseling. Neo-Confucianism itself has undergone development from its eleventh-century origins to the present-day scholarly journals. -/- The researcher does not believe the key issue in inter- disciplinary studies is whether psychology is being applied to philosophy or vice-versa. Neo-Confucianism pragmatically asserts that the true test of a philosophy rests in its ability to help the individual. Mere intellectual exercise contradicts the unity of knowledge and action. The thesis has five chapters. The existential therapy chapter uses a predominantly Western psychology format while the cognitive-behavioral therapy chapter uses Wang Yang-ming's Four Axiom Teaching as an outline. -/- The thesis also includes Neo-Confucian cognitive-moral development observations reminiscent of Lawrence Kohlberg's stage theories. Neo-Confucianism could be described as an education in evolving from preconventional to principled reasoning. Occasional parallels are drawn between process philosophy and Neo-Confucianism as well. -/- There is also a chapter in which Confucian commentaries are provided to actual case studies faced by Albert Ellis and Maxie Maultsby. A Chinese glossary is provided at the end of the introduction. There are five figures in the text, two of which are summarizing models in the conclusion. -/- . (shrink)

In recent years, feminist scholarship on emotional labor has proliferated. I identify a related but distinct form of care labor, hermeneutic labor. Hermeneutic labor is the burdensome activity of: understanding and coherently expressing one’s own feelings, desires, intentions, and movitations; discerning those of others; and inventing solutions for relational issues arising from interpersonal tensions. I argue that hermeneutic labor disproportionately falls on women’s shoulders in heteropatriachal societies, especially in intimate relationships between women and men. I also suggest that some of (...) the gendered burdens of emotional labor that feminist scholars point out would better be described as hermeneutic labor. Drawing on feminist philosophy as well as findings from social psychology and sociology, I argue that the exploitation of women’s hermeneutic labor is a pervasive element of what Sandra Bartky calls the ‘micropolitics’ of intimate relationships. The widespread expectation that women are relationship maintenance experts, as well as the prevalence of a gendered demand-withdraw pattern of communication, leads an exploitative situation to appear natural or even desirable, even as it leads to women’s dissatisfaction. This situation may be considered misogynistic in Kate Manne’s sense, where misogyny is a property of social environments rather than a worldview. (shrink)

The aim of this paper is to evaluate the critical success factors and investigate the benefits that might be gained once implementing Electronic Customer Relationship Management at HEI from employee perspective. The study conducted at Al Quds Open University in Palestine and data collected from (300) employee through a questionnaire which consist of four variables. A number of statistical tools were intended for hypotheses testing and data analysis, including Spearman correlation coefficient for Validity, reliability correlation using Cronbach’s alpha, and Frequency (...) and Descriptive analysis. The overall findings of the current study show that all the features were important for staff and it was critical success factors, at the same time, websites were providing all the features discussed by the theory whereas staff showed their willingness to use those features if provided. It is also discovered that implementing Electronic Customer Relationship Management can cause staff retention, were provided efficiently and needed to be improved. Research limitations: The survey findings were based on QOU employee in Palestine, UAE and KSA branches not included in the study. (shrink)

In recent decades, interest in non-monogamous intimate relationships has grown rapidly. Polyamory, relationship anarchy, consensual or ethical non-monogamy, and more have become popular in academic and public discourse. These practices destabilize the privileging of heterosexual nuclear families and the assumption that romantic coupledom is the ultimate form of love. Non-monogamous approaches flout cultural norms of exclusivity by avowing that intimacy is compatible with multiple dyadic and/or multi-party relationships. This article explores Simone de Beauvoir's theory and practice of non-monogamy in her (...) theoretical writings and diaries. (shrink)

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the (...) bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

Automatic detection of diseases and anatomical landmarks in medical images by the use of computers is important and considered a challenging process that could help medical diagnosis and reduce the cost and time of investigational procedures and refine health care systems all over the world. Recently, gastrointestinal (GI) tract disease diagnosis through endoscopic image classification is an active research area in the biomedical field. Several GI tract disease classification methods based on image processing and machine learning techniques have been proposed (...) by diverse research groups in the recent past. However, yet effective and comprehensive deep ensemble neural network-based classification model with high accuracy classification results is not available in the literature. In this thesis, we review ways and mechanisms to use deep learning techniques to research on multi-disease computer-aided detection about gastrointestinal and identify these images. We re-trained five state-of-the-art neural network architectures, VGG16, ResNet, MobileNet, Inception-v3, and Xception on the Kvasir dataset to classify eight categories that include an anatomical landmark (pylorus, z-line, cecum), a diseased state (esophagitis, ulcerative colitis, polyps), or a medical procedure (dyed lifted polyps, dyed resection margins) in the Gastrointestinal Tract. Our models have showed results with a promising accuracy which is a remarkable performance with respect to the state-of-the-art approaches. The resulting accuracies achieved using VGG, ResNet, MobileNet, Inception-v3, and Xception were 98.3%, 92.3%, 97.6%, 90% and 98.2%, respectively. As it appears, the most accurate result has been achieved when retraining VGG16 and Xception neural networks with accuracy reache to 98% due to its high performance on training on ImageNet dataset and internal structure that support classification problems.

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes the (...) same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (shrink)

I argue via examples that there are cases in which things that are not two distinct things qualitatively differ without contradiction. In other words, there are cases in which something differs from itself. Standard responses to such cases are to divide the thing into distinct parts, or to conceive of the thing under different descriptions, or to appeal to different times, or to deny that the property had is the property lacked. I show these responses to be unsatisfactory. I then (...) gather and systematize available ways of talking about such cases with phrases like ‘insofar as’, ‘qua’, ‘to the extent that’, ‘in some respect’, etc., while paying special attention to the scope of ‘not’ when used with these phrases. This allows me to show how we can speak of self-differing without contradiction. (shrink)

Diabetes is a major public health issue that affects the nations of our time to a large extent and is described as a non-communicable epidemic. Diabetes mellitus is a common disease where there is too much sugar (glucose) floating around in your blood. This occurs because either the pancreas can’t produce enough insulin or the cells in body have become resistant to insulin. The concentration in this paper is on diagnosis diabetes by designing a proposed expert system. The main goal (...) of this expert system is to get the appropriate diagnosing of the illness, dealing with it quickly, and tips for permanent treatment whenever possible is given out. SL5 object expert system language was used for designing and implementing the proposed expert system. (shrink)

Ontology, since Aristotle, has been conceived as a sort of highly general physics, a science of the types of entities in reality, of the objects, properties, categories and relations which make up the world. At the same time ontology has been for some two thousand years a speculative enterprise. It has rested methodologically on introspection and on the construction and analysis of elaborate world-models and of abstract formal-ontological theories. In the work of Quine and others this ontological theorizing in abstract (...) fashion about the world was supplemented by the study, based on the use of logical methods, of the ontological commitments or presuppositions embodied in scientific theories. In recent years both types of ontological study have found application in the world of information systems, for example in the construction of frameworks for knowledge representation and in database design and translation. As ontology is in this way drawn closer to the domain of real-world applications, the question arises as to whether it is possible to use empirical methods in studying ontological theories. More specifically: can we use empirical methods to test the ontological theories embodied in human cognition? We set forth the outlines of a framework for the formulation and testing of such theories as they relate to the specific domain of geographic objects and categories. (shrink)

Intuitions play an important role in contemporary philosophy. It is common for theories in epistemology, morality, semantics and metaphysics to be rejected because they are inconsistent with a widely and firmly held intuition. Our goal in this paper is to explore the role of epistemic intuitions in epistemology from a naturalistic perspective. Here is the question we take to be central: (Q) Ought we to trust our epistemic intuitions as evidence in support of our epistemological theories? We will understand this (...) question as employing an epistemic ‘ought’ – insofar as we aim at developing a correct epistemological theory, ought we to trust our epistemic intuitions as evidence for or against our epistemological theories? As it stands, (Q) needs further clarification. Whether something is trustworthy is relative to what (a) what it is and (b) what we’re asking it to do. Sam might trust Marie but not George to care for his children, while he might trust both to care for his pet fish. So in order to address (Q), we first need to explore two questions: What are epistemic intuitions? And what sort of epistemological theories do we want? We will take up each of these questions in the following sections. (shrink)

This paper considers three possible ways of understanding the claim that the American criminal justice system is racist: individualist, “patterns”-based, and ideology-based theories of institutional racism. It rejects an individualist explanation of institutional racism because such an explanation fails to explain the widespread prevalence of anti-black racism in this system or indeed in the United States. It considers a “patterns” account of institutional racism, where consistent patterns of disparate racial effect mimic the structure of intentional projects of racial subjugation like (...) slavery or Jim Crow. While a “patterns” account helpfully directs attention to the effects of policies and practices that make up an institution, it does not fully explain the deep roots of anti-blackness in the criminal justice system in the United States. The paper concludes by defending an ideology-based theory of institutional racism for understanding the criminal justice system because the stereotype of the black criminal has a mutually reinforcing relationship with the patterns of disparate outcome for black people in the criminal justice system. This relationship creates a looping effect where the stereotype of the black criminal fuels the disproportionate involvement of black people in the criminal justice system, and the disproportionate representation of black people with felony records, in prisons, brutalized in police encounters, and so on reinforces the idea that black people are especially prone to criminality. Ideological approaches to racism that integrate attention to the patterns of disparate effect best explain what it means to say that the criminal justice system is racist. (shrink)

This chapter identifies and explores a series of challenges raised by the clinical concept of delusion for theories which conceive autonomy as an agency rather than a status concept. The first challenge is to address the autonomy-impairing nature of delusions consistently with their role as grounds for full legal and ethical excuse, on the one hand, and psychopathological significance as key symptoms of psychoses, on the other. The second challenge is to take into account the full logical range of delusions, (...) which may take the form of true or false factual beliefs, positive or negative evaluations, as well as the paradoxical delusion of mental illness. The third and final challenge is to make room for non-pathological or, autonomy-preserving delusions and to offer a credible way of distinguishing between these and pathological or, autonomy-impairing delusions. By setting out these challenges, we are able to, firstly, distinguish between two separate conceptions of objectivity that may be at work in existing accounts of delusions and, secondly, to put a spotlight on an elusive yet inescapable notion of agential success that underlies our thinking about autonomy as well as mental disorder.

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

In this article, I present a two-pronged argument for the immorality of contemporary, asymmetric drone warfare, based on my new interpretations of the just war principles of “proportionality” and “moral equivalence of combatants” (MEC). The justification for these new interpretations is that drone warfare continues to this day, having survived despite arguments against it that are based on traditional interpretations of just war theory (including one from Michael Walzer). On the basis of my argument, I echo Harry Van der Linden’s (...) call for “an international treaty banning all weaponized UAV [uninhabited aerial vehicles].”. (shrink)

Abstract: Artificial Intelligence (AI) has rapidly evolved, offering transformative capabilities for business decision-making. This paper explores how AI can be leveraged to enhance strategic decision-making in business contexts. It examines the integration of AI-driven analytics, predictive modeling, and automation to improve decision accuracy and operational efficiency. By analyzing current applications and case studies, the paper highlights the opportunities AI presents, including enhanced data insights, risk management, and personalized customer experiences. Additionally, it addresses the challenges businesses face in adopting AI, such (...) as data privacy concerns, integration issues, and the need for skilled personnel. The paper concludes with recommendations for effectively implementing AI solutions to maximize their benefits while navigating potential pitfalls. (shrink)

In the present article, I offer a new reading of Hannah Arendt’s The Origins of Totalitarianism, specifically her argument that ideologies such as racism engender totalitarianism when the lonely and disenfranchised laborers of modern society develop a pathological fixation on formal logic, which I term “logomania.” That is, such logical deductions, from horrifically false premises, are the closest thing to thinking that individuals can engage in after their psyches, relationships, and communities have broken down. And it is only thus that (...) totalitarianism can achieve power, since it offers at least some form of connectedness and meaning, regardless how terrifying and violent. The danger persists, clearly, with the resurgence of the far Right, including in the extraordinary regime of Trump in the United States. From this I conclude that, along with the admirable calls to fight loneliness and rebuild our communities, we should also supplement all formal logical instruction and community education with instruction in creative thinking (including aesthetics), thereby discouraging the monomaniac reliance on formal logic as inadvertent weapon of totalitarianism.

The aim of this study was to identify the obstacles facing the application of knowledge management and its impact on performance at Palestine Technical University-Kadoorei from the point of view of employees and to detect the differences between the average views of the study sample on the subject of the study according to some variables such as (gender, nature of work, Education Level, specialization, years of experience). The study followed the descriptive analytical method and the questionnaire as a tool for (...) study. It was distributed to 74 employees. After the questionnaire was distributed, the data was collected and coded and entered into the computer and processed statistically using the SPSS program. The study found that the percentage of approval of the obstacles to the application of knowledge management at Palestine Technical University-Kadoorei differed between few and large, and the relative weight of the axis was complete (68.2). The degree of awareness of the workers of the reality of performance excellence at the University of Palestine Technical-Kadoorei was between medium and very large. There is an impact of the constraints of the application of knowledge management on performance excellence at Palestine Technical University-Kadoorei. In light of the results of the previous study, the researchers recommended that the importance of knowledge management should be taken into account in order to raise the university's reputation and reputation at home and abroad and improve its services to students and the local community. And to promote the exchange of experiences and knowledge with local, regional and international universities in order to enhance the knowledge and preserve it and provide modern and sophisticated scientific techniques and use them in administrative and academic work at the university.

Introduction and translation of “The Four Phases of Philosophy” by Franz Brentano.

These comments are part of a book symposium on Karen Bennett's book, _Making Things Up_.

Understanding Hume’s theory of space and time requires suspending our own. When theorizing, we think of space as one huge array of locations, which external objects might or might not occupy. Time adds another dimension to this vast array. For Hume, in contrast, space is extension in general, where being extended is having parts arranged one right next to the other like the pearls on a necklace. Time is duration in general, where having duration is having parts occurring one aft (...) er another like the notes of a song. Hume’s diff erent view stems from his empiricism, his reliance on experience and observation as the foundation of our concepts. Nothing in our experience suggests a single vast array of locations. Rather, we simply notice that bodies are similar insofar as they have lengths that can be compared. Likewise, nothing in our experience suggests a single dimension of time. Rather, we simply notice that diff erent successions are similar insofar as they have durations that can be compared. Th eorizing that these observations show there to be a single multidimensional array goes well beyond the evidence for Hume. As a skeptic, he fi nds himself unable to assent to theories that stray too far beyond the deliverances of the senses. For Hume, the ideas of space and time are each a general idea of simple—partless— objects arrayed in a certain manner. He argues that the structures of the ideas of space and time refl ect the structures of space and time. Th erefore, space and time are not infi - nitely divisible, and they are ways simple objects are arrayed. Consequently, there is no such thing as empty space nor time without change. (shrink)

There is growing concern that a global economic system fueled predominately by financial incentives may not maximize human flourishing and social welfare externalities. If so, this presents a challenge of how to get economic actors to adopt a more virtuous motivational mindset. Relying on historical, psychological, and philosophical research, we show how such a mindset can be instilled. First, we demonstrate that historically, financial self-interest has never in fact been the only guiding motive behind free markets, but that markets themselves (...) are representations of our individual and collective moral identities. Building on this understanding, we review the research on how economic incentives crowd out virtue-oriented concerns. We then introduce the concept of moral self-awareness (MSA), an evolving mindset informed by reflection on moral identity, namely what one’s actions say about oneself given the impacts on others or society that one’s action may effect. MSA comprises three fundamental aspects of virtue-oriented reasoning: pride, shame, and guilt. Finally, we offer a four-stage model anchored in systems theory, yielding ever more refined motivating strategies for maximizing human flourishing and social welfare externalities. (shrink)

Environmental health research produces scientific knowledge about environmental hazards crucial for public health and environmental justice movements that seek to prevent or reduce exposure to these hazards. The environment in environmental health research is conceptualized as the range of possible social, biological, chemical, and/or physical hazards or risks to human health, some of which merit study due to factors such as their probability and severity, the feasibility of their remediation, and injustice in their distribution. This paper explores the ethics of (...) identifying the relevant environment for environmental health research, as judgments involved in defining an environmental hazard or risk, judgments of that hazard or risk's probability, severity, and/ or injustice, as well as the feasibility of its remediation, all ought to appeal to non-epistemic as well as epistemic values. I illustrate by discussing the case of environmental lead, a housing-related hazard that remains unjustly distributed by race and class and is particularly dangerous to children. Examining a controversy in environmental health research ethics where researchers tested multiple levels of lead abatement in lead-contaminated households, I argue that the broader perspective on the ethics of environmental health research provided in the first part of this paper may have helped prevent this controversy.

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.

Consonant with the ongoing “aesthetic turn” in legal scholarship, this article pursues a new conception of law as poetry. Gestures in this law-as-poetry direction appear in all three main schools in the philosophy of law’s history, as follows. First, natural law sees law as divinely-inspired prophetic poetry. Second, positive law sees the law as a creative human positing (from poetry’s poesis). And third, critical legal theory sees these posited laws as calcified prose prisons, vulnerable to poetic liberation. My first two (...) sections interpret two texts at the intersections among these three theories, namely Percy Bysshe Shelley’s “A Defense of Poetry” and Alexis de Tocqueville’s Democracy in America. Shelley identifies a poetic rebirth in the ruins of natural law, suggesting a philosophy of law as “natural poesis.” And Tocqueville names several figurative aristocracies capable of redeploying aristocratic law against democratic despotism, suggesting a philosophy of law as “aristo-poetic counterforce.” Finally, I propose a new theory of law as poetry bridging these two theories, “natural aristo-poetic counterforce.”.

This paper has two aims: First, to provide an elucidation of the kind of meta-ethical programme at work in Mary Midgley's (1919-2018) Beast and Man: The Roots of Human Nature (published in 1978). Second, to make the case for Midgley's placement within the philosophical and philosophical-historical canon, specifically, as an important figure within the meta-ethical movement of ‘Neo-Aristotelian naturalism'. On historical and systematic grounds, I argue that Midgley should be classified as a neo-Aristotelian ethical naturalist notwithstanding the distinctive features of (...) Midgley’s specific brand of neo-Aristotelianism. In doing so, I suggest a more generally applicable family resemblance approach to the history of philosophy in order to classify and re-introduce into the canon figures in the history of philosophy that are in danger of falling into oblivion.

[This is an edited and improved version of "You Are Not Your Brain: Against 'Teaching to the Brain'" previously published in *Review of Higher Education and Self-Learning* 5(15), Summer 2012.] Since educators are always looking for ways to improve their practice, and since empirical science is now accepted in our worldview as the final arbiter of truth, it is no surprise they have been lured toward cognitive neuroscience in hopes that discovering how the brain learns will provide a nutshell explanation (...) for student learning in general. I argue that identifying the person with the brain is scientism (not science), that the brain is not the person, and that it is the person who learns. In fact the brain only responds to the learning of embodied experience within the extra-neural network of intersubjective communications. Learning is a dynamic, cultural activity, not a neural program. Brain-based learning is unnecessary for educators and may be dangerous in that a culturally narrow ontology is taken for granted, thus restricting our creativity and imagination, and narrowing the human community.

Kant identifies what are in fact Free Riders as the most noxious species of polemicists. Kant thinks polemic reduces the stature and authority of reason to a method of squabbling that destabilizes social equilibrium and portends disintegration into the Hobessian state of nature. In the first Critique, Kant proposes two textually related solutions to the Free Rider problem.

Criminal law practices in the US, including policing and incarceration, have drawn heavy criticism for their disproportionate impact on black people, particularly black men. At the same time, some feminist scholars and activists advocate for increases in criminal law responses to sexual assault, including expanding criminal statutes to cover more instances of sexual assault and increasing sentencing guidelines. These reforms are often justified by claims that criminal law should express more feminist values and reject sexist social schemas. This paper makes (...) the case that criminal legal interventions aimed at changing sexist social schemas, such as ‘rape culture,’ are unlikely to be successful because criminal law is effective at maintaining existing social norms, but bad at introducing novel ones. Similarly, in the US, criminality has been ideologically linked to blackness, so attempts to use the stigma of criminality to combat sexual violence are likely to reinforce anti-black racism. The very meaning of a criminal law depends on related social schemas, and the racist social schemas associated with criminality undermine the ability of criminal legal responses to present anti-sexist values. At best, criminal legal reforms aimed at expressing the equal dignity of women will be ambiguous because their meaning is negotiated by existing sexist and racist social schemas. Thus, penal expressivism cannot offer a justification for using criminal law to combat sexual assault. (shrink)

This paper considers the prospect of moral transhumanism from the perspective of theological virtue ethics. I argue that the pursuit of goodness inherent to moral transhumanism means that there is a compelling prima facie case for moral enhancement. However, I also show that the proposed enhancements would not by themselves allow us to achieve a life of virtue, as they appear unable to create or enhance prudence, the situational judgement essential for acting in accordance with virtue. I therefore argue that (...) moral enhancement technologies should take a limited or supporting role in moral development, which I call ‘moral supplementation’. (shrink)

This paper will argue that there is no such thing as introspective access to judgments and decisions. I t won't challenge the existence of introspective access to perceptual and imagistic states, nor to emotional feelings and bodily sensations. On the contrary, the model presented in Section 2 presumes such access. Hence introspection is here divided into two categories: introspection of propositional attitude events, on the one hand, and introspection of broadly perceptual events, on the other. I shall assume that the (...) latter exists while arguing that the fonner doesn't . Section I makes some preliminary points and distinctions, and outlines the scope of the argument. Section 2 presents and motivates the general model of introspection that predicts a divided result. Section 3 provides independent evidence for the conclusion that judgments and decisions aren't introspectable. Section 4 then replies to a number of objections to the argument, the most important of which is made from the perspective of so-called "dual systems theories" of belief formation and decision making, The upshot is a limited form of eliminativism about introspection, in respect of at least two core categories of propositional attitude.

In the words of Iris Murdoch, Mary Midgley’s Beast and Man built “an urgently needed bridge between science and philosophy”.1 While science and philosophy have never been entirely remote, Murdoch was right to observe the achievement of her friend, Midgley, in drawing a new and insightful connection between these disciplines. A bridge, more specifically, between scientific investigations into human and animal behaviour, and philosophical enquiries into the concept of human nature. A moral philosopher by trade, Midgley imbues the neo-Aristotelian understanding (...) of man as a ‘rational animal’ with the many traits (she argues) we share with our diverse earthly neighbours – nonhuman animals.

Numerous societal issues, from climate change to pandemics, require public engagement with scientific research. Such engagement reveals challenges that can arise when experts communicate with laypeople. One of the most common frameworks for framing these communicative interactions is the deficit model of science communication, which holds that laypeople lack scientific knowledge and/or positive attitudes towards science, and that imparting knowledge will fill knowledge gaps, lead to desirable attitude/behavior changes, and increase trust in science. §1 introduces the deficit model in more (...) detail and shows that adhering to this model often fails to achieve its aims, which motivates the main question of this chapter: how can Ludwik Fleck’s theory of thinking collectives address the persistent problem of deficit approaches in science communication? I suggest that it can do so by exposing the deficit model’s implicit assumption of an expert-lay divide. Accordingly, §2 lays out Fleck’s theory and §3 contrasts it with contemporary debates about science communication. Following this descriptive work, §4 draws on Fleck’s ideas to make four concrete suggestions for further questioning the expert-lay divide. (shrink)

Some theories of goodness are descriptively rich: they have much to say about what makes things good. Neo-Aristotelian accounts, for instance, detail the various features that make a human being, a dog, a bee good relative to facts about those forms of life. Famously, such theories of relative goodness tend to be comparatively poor: they have little or nothing to say about what makes one kind of being better than another kind. Other theories of goodness—those that take there to be (...) absolute goodness—are comparatively rich: they offer grounds for judging some types of things better than others because they have more absolute goodness. Moorean accounts, for example, can tell us that humans and human experiences are superior to bees and blades of grass. But such theories tend to be descriptively poor: they struggle to tell us in virtue of what this is so. In this essay we motivate and flesh out a view that splits the difference between accounts of goodness as relative and accounts of goodness as absolute. Such a view holds promise only if the mechanics of this kind of metaphysics of goodness can be worked out. Here we present a view on which the paradigm for absolute goodness is God and the paradigm for each kind of relative goodness is a divine idea. (shrink)

From folk tales to movies, stories possess features which naturally suit them to contribute to the growth of virtue. In this article I show that the fictional exemplars help the learner to grasp the moral importance of internal states and resolves a tension between existing kinds of exemplars discussed by virtue ethicists. Stories also increase the information conveyed by virtue terms and aid the growth of prudence. Stories can provide virtuous exemplars, inform learners as to the nature of the virtues (...) and offer practice in developing situational judgement. As such they are a significant resource for virtue ethics and moral education. (shrink)

This project was provoked by the almost nonexistent pushback from the Democratic liberal establishment to the (2020) exoneration of Kyle Rittenhouse, despite his acknowledged killing of two Black Lives Matters protesters against the police murder of George Floyd. It builds on three prior articles arguing for the revival of ancient Dionysian practice, Haitian Vodou, and Indigenous South American shamanism to empower leftist revolution. In essence, I propose an assemblage of spiritual practices that are accessible today for the neo-colonized 99% of (...) the global population, by synthesizing and reconstructing three democratic, lower-SES, Indigenous religions, all of which share a militant defiance of their respective tyrannical plutocracies. To avoid cultural appropriation, I center these reconstructed spiritual practices on the figure of the “mage,” a psychosocial healer loosely analogous to a shaman. And the mage’s signature activity, “magic,” I redefine naturalistically as free interpersonal performative action, practiced using two theoretical disciplines (philosophy and psychology) and two practical disciplines chosen by each mage. More precisely, Spirit/Dance channels the “spirits” of dead ancestors, historical figures, legendary heroes, mythical beings, and fictional characters, into the three ultimate objectives of “mindfulness” for psyches/souls, “liberation” for mindful bodies, and “social justice” for liberated communities, indirectly empowering long-term revolution.

The study aimed at measuring the dominant pattern of leadership and its relation to the performance of the administrative staff in the Palestinian universities. The study community consists of all the administrative staff from Al-Azhar University and the Islamic University, and through the census of the study society it was found to consist of (655) administrative staff. In order to achieve the objectives of the study, the researchers used the method of random sample in the study, and the study was (...) conducted on a sample of (221) administrative staff of the surveyed universities and the response rate was (82.35%). The study found that there is a high degree of satisfaction with the Dominant Pattern of Leadership in the Palestinian universities in Gaza Strip from the point of view of the administrative staff, which reached (71.67%). There is a high level of performance from the point of view of administrative staff, with a percentage of (82.53%). There is a direct correlation between the dominant pattern of leadership and the functional Performance of Administrative Staff, the absence of differences between the sample according to the gender variable in their perception of the dominant pattern of leadership and the functional Performance of Administrative Staff, the absence of differences in the perception of employees of the dominant pattern of leadership and the functional Performance of Administrative Staff depending on the age variable. There are differences of statistical significance according to the variable of scientific qualification in the Dominant Pattern of Leadership, while there were no differences in performance, the differences in the dominant pattern of leadership according to the scientific qualification were in favor of those who obtained the diploma degree compared to other practical qualifications, the absence of differences in the perception of employees of the dominant pattern of leadership and the functional Performance of Administrative Staff depending on the variable years of service, the absence of differences in the perception of employees of the dominant pattern of leadership and the functional Performance of Administrative Staff depending on the variable level of career (Director, Head of Department, and Administrative Officer). There were differences in the perception of workers to the dominant pattern of leadership depending on the variable of the workplace, where there were differences in favor of workers in deanships and colleges compared with the workers in the technical departments. While there were no differences in job performance according to the workplace variable, the existence of differences in the perception of workers to the dominant pattern of leadership depending on the university in which they work in favor of the Islamic University and the absence of differences in performance between the Islamic University and Al-Azhar University. The study reached a number of recommendations, the most important of which is that the interest of the managements of the Palestinian universities in improving the dominant pattern of leadership, to give universities the opportunity to participate in decision-making, the continued administration of universities interest and continuous improvement of the performance of its employees, enhance the periodic evaluation of job performance and to inform employees and express their opinion, solving workers' problems and giving them the opportunity to contribute to solving their own problems, the use of the staff rotation method periodically and strengthening the democratic the dominant pattern of leadership and empowering university staff. -/- .

Upshot: In our target article we claimed that, at least since Weber and Varela, enactivism has incorporated a theoretical commitment to one important aspect of Jonas’s philosophical biology, namely its anthropomorphism, which is at odds with the methodological commitments of modern science. In this general reply we want to clarify what we mean by anthropomorphism, and explain why we think it is incompatible with science. We do this by spelling out what we call the “Jonasian inference,” i.e., the idea that (...) we are entitled, based on our first-person experience of teleology, to take the appearance of teleology in other living beings at face value.
