Forty years have passed since video-games were first made widely available to the public and subsequently playing games has become a favorite past-time for many. Players continuously engage with dynamic visual displays with success contingent on the time-pressured deployment, and flexible allocation, of attention as well as precise bimanual movements. Evidence to date suggests that both brief and extensive exposure to video-game play can result in a broad range of enhancements to various cognitive faculties that generalize beyond the original context. (...) Despite promise, video-game research is host to a number of methodological issues that require addressing before progress can be made in this area. Here an effort is made to consolidate the past 30 years of literature examining the effects of video-game play on cognitive faculties and, more recently, neural systems. Future work is required to identify the mechanism that allows the act of video-game play to generate such a broad range of generalized enhancements. (shrink)

Video-game play (particularly “action” video-games) holds exciting promise as an activity that may provide generalized enhancement to a wide range of perceptual and cognitive abilities (for review see Latham et al., 2013a). However, in this article we make the case that to assess accurately the effects of video-game play researchers must better characterize video-game experience and expertise. This requires a more precise and objective assessment of an individual's video-game history and skill level, and making finer distinctions between video-games that fall (...) under the umbrella of “action” games. Failure to consider these factors may partly be responsible for mixed findings (see Boot et al., 2011). (shrink)

Twenty-two experienced action video-game players (AVGPs) and 18 non-VGPs were tested on a pen-and-paper line bisection task that was untimed. Typically, right-handers bisect lines 2 % to the left of true centre, a bias thought to reflect the dominance of the right-hemisphere for visuospatial attention. Expertise may affect this bias, with expert musicians showing no bias in line bisection performance. Our results show that experienced-AVGPs also bisect lines with no bias with their right hand and a significantly reduced bias with (...) their left hand compared to non-AVGPs. Bisections by experienced-AVGPs were also more precise than those of non-AVGPs. These findings show the cognitive proficiencies of experienced-AVGPs can generalize beyond computer based tasks, which resemble their training environment. (shrink)

Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG) recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT) in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum 8 years experience, and (...) maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years). Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented). IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

Learner’s attitude towards modular distance learning catches uncertainties as a world crisis occurs up to this point. As self-learning modules (SLMs) become a supplemental means of learning in new normal education, this study investigated efficiency towards the learners’ attitude and performance. Specifically, the study described the learners’ profile and their attitude and performance towards SLMs. It also ascertained the relationship between the learner’s profile with their attitude and performance, as well as the relationship between attitude and performance relevant to SLMs. (...) A descriptive-correlational research design was employed in the study with 88 non-randomly chosen participants from secondary schools in West Philippines. The learners’ GWA (general weighted average) was used to determine their performance and a survey questionnaire for their profile and attitude. Frequency counts, percentage, and Spearman’s rank correlation coefficient were used to analyze the data gathered with the aid of Jamovi software. Results revealed a strong correlation between attitude and performance, but there was no link between learner’s attitude and performance as to the learner’s profile. It was affirmed that attitude is a compelling factor that is related with performance. Hence, this research has broader ramifications that can direct the Bureau of Learning Delivery to orient the module writers to further contextualize the learning materials that can compound learner’s disposition and academic performance.

Both short and long-term video-game play may result in superior performance on visual and attentional tasks. To further these findings, we compared the performance of experienced male video-game players (VGPs) and non-VGPs on a Simon-task. Experienced-VGPs began playing before the age of 10, had a minimum of 8 years of experience and a minimum play time of over 20 h per week over the past 6 months. Our results reveal a significantly reduced Simon-effect in experienced-VGPs relative to non-VGPs. However, this (...) was true only for the right-responses, which typically show a greater Simon-effect than left-responses. In addition, experienced-VGPs demonstrated significantly quicker reaction times and more balanced left-versus-right-hand performance than non-VGPs. Our results suggest that experienced-VGPs can resolve response-selection conflicts more rapidly for right-responses than non-VGPs, and this may in part be underpinned by improved bimanual motor control.

The essays in this volume explore those aspects of Kant’s writings which concern issues in the philosophy of mind. These issues are central to any understanding of Kant’s critical philosophy and they bear upon contemporary discussions in the philosophy of mind. Fourteen specially written essays address such questions as: What role does mental processing play in Kant’s account of intuition? What kinds of empirical models can be given of these operations? In what sense, and in what ways, are intuitions object-dependent? (...) How should we understand the nature of the imagination? What is inner sense, and what does it mean to say that time is the form of inner sense? Can we cognize ourselves through inner sense? How do we self-ascribe our beliefs and what role does self-consciousness play in our judgments? Is the will involved in judging? What kind of knowledge can we have of the self ? And what kind of knowledge of the self does Kant proscribe? These essays showcase the depth of Kant’s writings in the philosophy of mind, and the centrality of those writings to his wider philosophical project. Moreover, they show the continued relevance of Kant’s writings to contemporary debates about the nature of mind and self. Contents: 0. Introduction Anil Gomes and Andrew Stephenson 1.

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.

There is no doubt that custard apple diseases are among the important reasons that destroy the Custard Apple plant and its agricultural crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases is a good step to provide the appropriate and correct treatment. Determining the treatment with high accuracy depends on the method used to correctly diagnose the disease, expert systems can greatly help in avoiding damage to these plants. The expert system correctly diagnoses (...) Custard Apple disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: A specialized syllable language system was established for the diagnosis of Custard Apple plant disease. (shrink)

The study aimed to identify the relationship between correcting the deviations in the measurement of performance and achieving the objectives of control and the performance of the job at the Islamic University in the Gaza Strip. To achieve the objectives of the research, the researchers used the descriptive analytical approach to collect information. The questionnaire consisted of (20) statements distributed to three categories of employees of the Islamic University (senior management, faculty members, their assistants and members of the administrative board). (...) A random sample of 314 employees was selected and 276 responses were retrieved with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter, process, and analyze the data. The results of the study showed a positive relationship between correcting deviations in performance measurement and achieving the control objectives represented by the functional performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants, and the administrative board), where the relative weight of all the paragraphs was (74.25%). The study recommended the need to ensure that the actual performance of the planned performance is matched and decisions are taken to correct the serious deviations and take the necessary measures in terms of retraining and change in regulations, wages and bonuses and punishment of the culprit, neglect and negligence by mistake.

The internet provides us with a multitude of ways of interacting with one another. In discussions about how technological innovations impact and shape our interpersonal interactions, there is a tendency to assume that encountering people online is essentially different to encountering people offline. Yet, individuals report feeling a sense of togetherness with one another online that echoes offline descriptions. I consider how we can understand people’s experiences of being together with others online, at least in certain instances, as arising out (...) of their feeling together as a we. Using Walther’s phenomenological framework of communality, I explore whether the following might take place online: habitual communal experiences and actual we-experiences. While neither of these sketches amount to a full account of how we find ourselves with others online, I suggest that they reveal how insights from the phenomenology of sociality can be used to deepen our understanding of online communality. What is more, I suggest that the strength of this approach is that in some cases it allows us to circumvent tricky questions about embodiment online and, in others, prompts us to ask to what extent a fully-embodied interaction is really required for we-experiences.

In a recent article, Ethan Bradley and Mark Navin (2021) argue that vaccine refusal is not akin to free riding. Here, I defend one connection between vaccine refusal and free riding and suggest that, when viewed in conjunction with their other arguments, this might constitute a reason to mandate Covid-19 vaccination.

How could the initial, drastic decisions to implement “lockdowns” to control the spread of COVID-19 infections be justifiable, when they were made on the basis of such uncertain evidence? We defend the imposition of lockdowns in some countries by first, and focusing on the UK, looking at the evidence that undergirded the decision, second, arguing that this provided us with sufficient grounds to restrict liberty given the circumstances, and third, defending the use of poorly-empirically-constrained epidemiological models as tools that can (...) legitimately guide public policy.

At the beginning of the COVID-19 pandemic, high hopes were put on digital contact tracing, using mobile phone apps to record and immediately notify contacts when a user reports as infected. Such apps can now be downloaded in many countries, but as second waves of COVID-19 are raging, these apps are playing a less important role than anticipated. We argue that this is because most countries have opted for app configurations that cannot provide a means of rapidly informing users of (...) likely infections while avoiding too many false positive reports. Mathematical modelling suggests that differently configured apps have the potential to do this. These require, however, that some pseudonymised data be stored on a central server, which privacy advocates have cautioned against. We contend that their influential arguments are subject to two fallacies. First, they have tended to one-sidedly focus on the risks that centralised data storage entails for privacy, while paying insufficient attention to the fact that inefficient contact tracing involves ethical risks too. Second, while the envisioned system does entail risks of breaches, such risks are also present in decentralised systems, which have been falsely presented as ‘privacy preserving by design’. When these points are understood, it becomes clear that we must rethink our approach to digital contact tracing in our fight against COVID-19. There are no data in this work. (shrink)

During the Covid-19 pandemic we increasingly turned to technology to stay in touch with our family, friends, and colleagues. Even as lockdowns and restrictions ease many are encouraging us to embrace the replacement of face-to-face encounters with technologically mediated ones. Yet, as philosophers of technology have highlighted, technology can transform the situations we find ourselves in. Drawing insights from the phenomenology of sociality, we consider how digitally-enabled forms of communication and sociality impact our experience of one another. In particular, we (...) draw attention to the way in which our embodied experience of one another is altered when we meet in digital spaces, taking as our focus the themes of perceptual access, intercorporeality, shared space, transitional spaces, and self-presentation. In light of the way in which technological mediation alters various dimensions of our social encounters, we argue that digital encounters constitute their own forms of sociality requiring their own phenomenological analysis. We conclude our paper by raising some broader concerns about the very framework of thinking about digitally and non-digitally mediated social encounters simply in terms of replacement. (shrink)

The notion of respect for autonomy dominates bioethical discussion, though what qualifies precisely as autonomous action is notoriously elusive. In recent decades, the notion of autonomy in medical contexts has often been defined in opposition to the notion of autonomy favoured by theoretical philosophers. Where many contemporary theoretical accounts of autonomy place emphasis on a condition of “authenticity”, the special relation a desire must have to the self, bioethicists often regard such a focus as irrelevant to the concerns of medical (...) ethics, and too stringent for use in practical contexts. I argue, however, that the very condition of authenticity that forms a focus in theoretical philosophy is also essential to autonomy and competence in medical ethics. After tracing the contours of contemporary authenticity-based theories of autonomy, I consider and respond to objections against the incorporation of a notion of authenticity into accounts of autonomy designed for use in medical contexts. By looking at the typical problems that arise when making judgments concerning autonomy or competence in a medical setting, I reveal the need for a condition of authenticity—as a means of protecting choices, particularly high-stakes choices, from being restricted or overridden on the basis of intersubjective disagreement. I then turn to the treatment of false and contestable beliefs, arguing that it is only through reference to authenticity that we can make important distinctions in this domain. Finally, I consider a potential problem with my proposed approach; its ability to deal with anorexic and depressive desires. (shrink)

In this paper, we introduce the Japanese philosopher Tetsurō Watsuji’s phenomenology of aidagara (“betweenness”) and use his analysis in the contemporary context of online space. We argue that Watsuji develops a prescient analysis anticipating modern technologically-mediated forms of expression and engagement. More precisely, we show that instead of adopting a traditional phenomenological focus on face-to-face interaction, Watsuji argues that communication technologies — which now include Internet-enabled technologies and spaces — are expressive vehicles enabling new forms of emotional expression, shared experiences, (...) and modes of betweenness that would be otherwise inaccessible. Using Watsuji’s phenomenological analysis, we argue that the Internet is not simply a sophisticated form of communication technology that expresses our subjective spatiality (although it is), but that it actually gives rise to new forms of subjective spatiality itself. We conclude with an exploration of how certain aspects of our online interconnections are hidden from lay users in ways that have significant political and ethical implications. (shrink)

Uptake is typically understood as the hearer’s recognition of the speaker’s communicative intention. According to one theory of uptake, the hearer’s role is merely as a ratifier. The speaker, by expressing a particular communicative intention, predetermines what kind of illocutionary act she might perform. Her hearer can then render this act a success or a failure. Thus the hearer has no power over which act could be performed, but she does have some power over whether it is performed. Call this (...) the ratification theory of uptake. Several philosophers have recently endorsed an alternative theory of uptake, according to which the hearer can determine the nature of the act the speaker performs. According to this theory, if the hearer regards an utterance as illocutionary act y, then it is act y, even if the speaker intended to perform act x. Call this the constitution theory of uptake. The purported advantage of this theory is that it identifies a common but underanalysed way in which speakers can be silenced. I argue that despite its initial intuitive pull, the constitution theory of uptake should be rejected. It is incompatible with ordinary intuitions about speech, it entails a conceptual impossibility, and it has unsavoury political implications, entailing that marginalised speakers barely qualify as agents.

Despite its long history of investigating sociality, phenomenology has, to date, said little about online sociality. The phenomenological tradition typically claims that empathy is the fundamental way in which we experience others and their experiences. While empathy is discussed almost exclusively in the context of face-to-face interaction, I claim that we can empathetically perceive others and their experiences in certain online situations. Drawing upon the phenomenological distinction between the physical, objective body and the expressive, lived body, I: (i) highlight that (...) empathy involves perceiving the other’s expressive, lived body, (ii) show that the lived body is not tied to the physical body and that empathy can take place outside of face-to-face interactions, and (iii) argue that the lived body can enter online space and is empathetically available to others there. I explore two ways in which the other’s lived body enters online space and can be empathetically perceived: first, in cases where our face-to-face encounter is technologically-mediated over video link and, second, by showing how the other’s texts, as speech, can form part of the other’s lived body. Investigating empathy online not only furthers our understanding of online encounters but also leads to a refined conception of empathy more generally. (shrink)

Anorexia Nervosa (AN) is an eating disorder characterised by self-starvation. Accounts of AN typically frame the disorder in individualistic terms: e.g., genetic predisposition, perceptual disturbances of body size and shape, experiential bodily disturbances. Without disputing the role these factors may play in developing AN, we instead draw attention to the way disordered eating practices in AN are actively supported by others. Specifically, we consider how Pro-Anorexia (ProAna) websites—which provide support and solidarity, tips, motivational content, a sense of community, and understanding (...) to individuals with AN—help drive and maintain AN practices. We use C. Thi Nguyen’s work on epistemic “echo chambers”, along with Maria Lugones’ work on “worlds” and “ease”, to explore the dynamics of these processes. Adopting this broader temporal and intersubjective perspective, we argue, not only helps to further illuminate the experiential character of AN but also has important clinical and therapeutic significance.

In this paper I offer a philosophical analysis of the act of ‘liking’ a post on social media. First, I consider what it means to ‘like’ something. I argue that ‘liking’ is best understood as a phatic gesture; it signals uptake and anoints the poster’s positive face. Next, I consider how best to theorise the power that comes with amassing many ‘likes’. I suggest that ‘like’ tallies alongside posts institute and record a form of digital social capital. Finally, I consider (...) whether ‘likes’ have ultimately improved online discourse. I argue that while the ‘liking’ function itself is relatively innocuous, public ‘like’ tallies introduce a corrosive motivation to online communication. By making the prospect of increased social capital perpetually salient to us, they encourage us to prioritise high levels of engagement over meaningful engagement. (shrink)

At this stage of the COVID-19 pandemic, two policy aims are imperative: avoiding the need for a general lockdown of the population, with all its economic, social and health costs, and preventing the healthcare system from being overwhelmed by the unchecked spread of infection. Achieving these two aims requires the consideration of unpalatable measures. Julian Savulescu and James Cameron argue that mandatory isolation of the elderly is justified under these circumstances, as they are at increased risk of becoming severely ill (...) from COVID-19, and are thus likely to put disproportionate strain on limited healthcare resources. However, their arguments for this strategy are contingent on the lack of viable alternatives. We suggest that there is a possible alternative: a mandatory, centralised contact-tracing app. We argue that this strategy is ethically preferable to the selective isolation of the elderly, because it does not target members of a certain group, relying instead on the movements of each individual, and because it avoids the extended isolation of certain members of the society. Although this type of contact-tracing app has its drawbacks, we contend that this measure warrants serious consideration. (shrink)

At the beginning of the COVID-19 pandemic, high hopes were placed on digital contact tracing. Digital contact tracing apps can now be downloaded in many countries, but as further waves of COVID-19 tear through much of the northern hemisphere, these apps are playing a less important role in interrupting chains of infection than anticipated. We argue that one of the reasons for this is that most countries have opted for decentralised apps, which cannot provide a means of rapidly informing users (...) of likely infections while avoiding too many false positive reports. Centralised apps, in contrast, have the potential to do this. But policy making was influenced by public debates about the right app configuration, which have tended to focus heavily on privacy, and are driven by the assumption that decentralised apps are “privacy preserving by design”. We show that both types of apps are in fact vulnerable to privacy breaches, and, drawing on principles from safety engineering and risk analysis, compare the risks of centralised and decentralised systems along two dimensions, namely the probability of possible breaches and their severity. We conclude that a centralised app may in fact minimise overall ethical risk, and contend that we must reassess our approach to digital contact tracing, and should, more generally, be cautious about a myopic focus on privacy when conducting ethical assessments of data technologies.

Research limitations: The survey findings were based on QOU employee in Palestine, UAE and KSA branches not included in the study. (shrink)

Respect for autonomy and beneficence are frequently regarded as the two essential principles of medical ethics, and the potential for these two principles to come into conflict is often emphasised as a fundamental problem. On the one hand, we have the value of beneficence, the driving force of medicine, which demands that medical professionals act to protect or promote the wellbeing of patients or research subjects. On the other, we have a principle of respect for autonomy, which demands that we (...) respect the self-regarding decisions of individuals. As well as routinely coming into opposition with the demands of beneficence in medicine, the principle of respect for autonomy in medical ethics is often seen as providing protection against beneficial coercion (i.e. paternalism) in medicine. However, these two values are not as straightforwardly opposed as they may appear on the surface. In fact, the way that we understand autonomy can lead us to implicitly sanction a great deal of paternalistic action, or can smuggle in paternalistic elements under the guise of respect for autonomy. -/- This paper is dedicated to outlining three ways in which the principle of respect for autonomy, depending on how we understand the concept of autonomy, can sanction or smuggle in paternalistic elements. As the specific relationship between respect for autonomy and beneficence will depend on how we conceive of autonomy, I begin by outlining two dominant conceptions of autonomy, both of which have great influence in medical ethics. I then turn to the three ways in which how we understand or employ autonomy can increase or support paternalism: firstly, when we equate respect for autonomy with respect for persons; secondly, when our judgements about what qualifies as an autonomous action contain intersubjective elements; and thirdly, when we expect autonomy to play an instrumental role, that is, when we expect people, when they are acting autonomously, to act in a way that promotes or protects their own wellbeing. I then provide a proposal for how we might work to avoid this. I will suggest that it may be impossible to fully separate paternalistic elements out from judgements about autonomy. Instead, we are better off looking at why we are motivated to use judgements about autonomy as a means of restricting the actions of patients or research subjects. I will argue that this is a result of discomfort about speaking directly about our beneficent motivations in medical ethics. Perhaps we can reduce the incentive to smuggle in these beneficent motivations under the guise of autonomy by talking directly about beneficent motivations in medicine. This will also force us to recognise paternalistic motivations in medicine when they appear, and to justify paternalism where it occurs. (shrink)

Anorexia Nervosa (AN) is a complex disorder characterised by self-starvation, an act of self-destruction. It is often described as a disorder marked by paradoxes and, despite extensive research attention, is still not well understood. Much AN research focuses upon the distorted body image that individuals with AN supposedly experience. However, based upon reports from individuals describing their own experience of AN, I argue that their bodily experience is much more complex than this focus might lead us to believe. Such research (...) often presents an overly cognitive understanding of bodily experience in AN, underplaying the affective, felt experience of individuals with AN, as well as descriptions of empowerment, strength and control reported in the early stages of AN. This paper seeks to enrich our understanding of bodily experience in AN as it progresses throughout the various stages of the disorder. I show how the classical phenomenological distinction between the body-as-subject and the body-as-object, as well as Leder’s conception of the visceral body, can inform our understanding of bodily experience in AN. I suggest that the project of self-starvation is an attempt to overcome the noisy demands of the visceral body, which are experienced as threatening the body-as-subject, through a process of objectifying the body-as-object. By cashing out AN as a project of radical bodily control that, tragically, comes to control the individual, we can capture important aspects of the bodily experience of AN and the temporal progression of the disorder. -/- .

The study aims to identify the efficiency of the university education performance from the perspective of postgraduate and undergraduate students in international and Palestinian universities. The analytical descriptive approach was used for this purpose and the questionnaire was used as a main tool for data collection. The study community consists of: post graduate students, (23850) graduate students and (146355) undergraduate students. The sample of the study was 378 graduate students and 383 undergraduate students. The random stratified sample was used. The (...) Statistical Package of Social Sciences (SPSS) was also used for data analysis. The study reached a number of results, the most important of which are: The level of efficiency of educational performance in Palestinian and international universities from the point of view of postgraduate and undergraduate students was high.

Recently, bioethicists and the UNCRPD have advocated for supported medical decision-making on behalf of patients with intellectual disabilities. But what does supported decision-making really entail? One compelling framework is Anita Silvers and Leslie Francis’ mental prosthesis account, which envisions supported decision-making as a process in which trustees act as mere appendages for the patient’s will; the trustee provides the cognitive tools the patient requires to realize her conception of her own good. We argue that supported decision-making would be better understood (...) as a collaborative process, giving patients with intellectual disabilities the opportunity to make decisions in a respectful relationship with trusted others. We offer an alternative account of supported decision-making where the primary constraint is to protect the patient from domination by the trustee. This is advantageous in its preservation of the prospects for genuine collaboration, for the mental prosthesis approach ultimately reinforces a problematic ideal of isolated patient self-determination.

In this chapter, I explore how experiences of social belonging might emerge and be sustained in online communities, drawing from the work on rituals by Randall Collins. I argue that rather than viewing mediated interactions in terms of whether they are suitable substitutes for face-to-face interactions, we should consider mediated encounters in their own right. This allows us to recognize the creative ways that people can create rituals in a mediated setting and thus support and create a sense of belonging (...) with others online. I also highlight how some online platforms not only support online rituals but that they are well-positioned to create and circulate collective symbols (or sacred objects) of groups and, thus, can continue to scaffold and sustain on-going feelings of belonging.

Speech act theorists tend to hold that the illocutionary force of an utterance is determined by one interlocutor alone: either the speaker or the hearer. Yet experience tells us that the force of our utterances is not determined unilaterally. Rather, communication often feels collaborative. In this paper, I develop and defend a collaborative theory of illocutionary force, according to which the illocutionary force of an utterance is determined by an agreement reached by the speaker and the hearer. This theory, which (...) builds upon linguistic and sociological work on adjacency pairs and conversational interaction, can accommodate the complexity of speaker intentions (which may be disjunctive, indeterminate, and/or inconsistent over time), and renders speech act theory more compatible with theories of common ground.

Abstract: Smoke detectors are critical devices for early fire detection and life-saving interventions. This research paper explores the application of Artificial Neural Networks (ANNs) in smoke detection systems. The study aims to develop a robust and accurate smoke detection model using ANNs. Surprisingly, the results indicate a 100% accuracy rate, suggesting promising potential for ANNs in enhancing smoke detection technology. However, this paper acknowledges the need for a comprehensive evaluation beyond accuracy. It discusses potential challenges, such as overfitting, dataset size, (...) and class imbalance, and presents strategies employed to address these issues. Additionally, the paper emphasizes the importance of alternative evaluation metrics, including precision, recall, and F1-score, to assess the model's performance comprehensively. Detailed information regarding the model architecture, data preprocessing, and hyperparameter tuning is provided to enhance the reproducibility of the research. The study also discusses ethical considerations and the implications of false positives and false negatives in smoke detection applications. While achieving 100% accuracy is a notable accomplishment, this paper calls for cautious interpretation and further validation in real-world settings. It concludes by highlighting areas for future research and improvement in smoke detection technology, emphasizing the need for practical deployment and the reduction of false alarms. (shrink)

Medical ethicists conventionally assume that the requirement to employ informed consent procedures is grounded in autonomy. It seems intuitively plausible that providing information to an agent promotes his autonomy by better allowing him to steer his life. However, James Taylor questions this view, arguing that any notion of autonomy that grounds a requirement to inform agents turns out to be unrealistic and self-defeating. Taylor thus contends that we are mistaken about the real theoretical grounds for informed consent procedures. Through analysing (...) Taylor's arguments and showing that they do not stand up to scrutiny, it is possible to defend the view that autonomy is a plausible theoretical basis for informed consent, and to enhance our understanding of the relationship between autonomy and informed consent.

Individuals suffering from depression consistently report experiencing a lack of connectedness with others. David Karp (2017, 73), in his memoir and study of depression, has gone so far to describe depression as “an illness of isolation, a disease of disconnectedness”. It has become common, in phenomenological circles, to attribute this social impairment to the depressed individual experiencing their body as corporealized, acting as a barrier between them and the world around them (Fuchs 2005, 2016). In this paper, I offer an (...) alternative view of the experience of social disconnectedness in depression, suggesting that rather than necessarily experiencing their body as object-like, the depressed individual’s bodily is saturated with experiences of lethargy, tiredness, heaviness, sadness, hopelessness and so on, to the exclusion of being able to bodily connect to others. I suggest that depression does not involve a complete social impairment but a specific impairment of affective forms of interpersonal experience. (shrink)

Andrea Wiggins and John Wilbanks’ article (2019) presents us with a welcome overview of the neglected, novel ethical issues raised by the advent of citizen science in health and biomedical contexts.

This problem, however, is particularly illustrative of the “ethics gap” between traditional medical settings and new public-driven scientific practices, emphasized by Wiggins and (...)

In accordance with a recent statement released by the World Health Organization, the Canadian province of Ontario is moving to ban payment for plasma donation. This is partially based on contentions that remuneration for blood and blood products undermines autonomy and personal dignity. This paper is dedicated to evaluating this claim. I suggest that traditional autonomy-based arguments against commodification of human body parts and substances are less compelling in the context of plasma donation in Canada, but that there is another (...) autonomy-based objection to paid plasma donation that has not received sufficient attention. Namely, the stigma that surrounds exchanging plasma for payment makes it difficult to make an autonomous decision to engage in this activity. I suggest that this problem can be overcome in one of two ways; by banning payment for plasma, or by reducing the stigma surrounding this practice. I provide an indication of how we might work to achieve the latter, contending that this possibility should be taken seriously, due to the difficulties in achieving a sufficient supply of plasma without remuneration.

Gerben Meynen (2019) invites us to consider the potential ethical implications of what he refers to as “thought apprehension” technology for psychiatric practice, that is, technologies that involve recording brain activity, and using this to infer what people are thinking (or intending, desiring, feeling, etc.). His article is wide-ranging, covering several different ethical principles, various situations psychiatrists might encounter in therapeutic, legal and correctional contexts, and a range of potential incarnations of this technology, some more speculative than others. Although Meynen’s (...) article raises some highly relevant potential implications of some “thought apprehension”-based neurotechnologies, which are certainly worthy of further exploration, I suggest that Meynen’s analysis is beset by two problems. First, some of the technologies that form the focus of his discussion are too speculative, and second, due to the many issues under consideration, some problems are not adequately characterized, relevant ethical principles are misidentified, and valuable literature is not sufficiently engaged with. Consideration of these weaknesses might allow us to better see how to conduct a fruitful analysis of speculative neurotechnologies. (shrink)

Cette recherche vise à comprendre comment les situations présentes dans la formation à l’enseignement peuvent soutenir le fonctionnement et la réussite de l’apprentissage professionnel des enseignants en formation. Nous cherchons à identifier les points de rencontre entre les situations d’activité professionnelle, les situations d’apprentissage professionnel et les situations de formation. Nous tenterons d’analyser le rôle que peuvent jouer certains dispositifs visant à soutenir un processus de professionnalisation que nous définissons au regard d’une finalité : la construction de savoirs professionnels. L’originalité de cette recherche est la convocation des travaux de Gaston Bachelard pour élaborer le cadre théorique permettant la lecture et l’interprétation des résultats. (shrink)

This text presents a few preliminary results of research currently being conducted at the Université de Sherbrooke’s Research Institute on Educational Practices. The study seeks to understand how situations presented in teacher education can support the functioning and success of trainee teachers’ professional learning. The article’s aim is to identify the points of convergence between situations of professional activity, situations of professional learning, and training situations. The text will attempt to analyze the role that can be played by certain training (...) structures that seek to support a professionalization process that we define in terms of a general aim: the construction of professional knowledge. The originality of this research lies in that it draws on the work of Gaston Bachelard to develop a theoretical frame enabling a reading and interpretation of the results.

While there seems to be much evidence that perceptual states can occur without being conscious, some theorists recently express scepticism about unconscious perception. We explore here two kinds of such scepticism: Megan Peters and Hakwan Lau's experimental work regarding the well-known problem of the criterion -- which seems to show that many purported instances of unconscious perception go unreported but are weakly conscious -- and Ian Phillips' theoretical consideration, which he calls the 'problem of attribution' -- the worry that many (...) purported examples of unconscious perception are not perceptual, but rather merely informational and subpersonal. We argue that these concerns do not undermine the evidence for unconscious perception and that this sceptical approach results in a dilemma for the sceptic, who must either deny that there is unconscious mentality generally or explain why perceptual states are unique in the mind such that they cannot occur unconsciously. Both options, we argue, are problematic. (shrink)

Papaya is a tropical fruit with a green cover, yellow pulp, and a taste between mango and cantaloupe, having commercial importance because of its high nutritive and medicinal value. The process of sorting papaya fruit based on maturely is one of the processes that greatly determine the mature of papaya fruit that will be sold to consumers. The manual grading of papaya fruit based on human visual perception is time-consuming and destructive. The objective of this paper is to the status (...) classification of papaya fruits if it's mature or partially matured or unmatured. A deep learning technique that was extensively applied to image recognition was used. The trained model achieved an accuracy of 100% on a held-out test set, demonstrating the feasibility of this approach. Classification model of VGG16 achieved a 100% accuracy and 112 seconds of training time. (shrink)

Euthanasia and assisted suicide have proved to be very contentious topics in medical ethics. Some ethicists are particularly concerned that allowing physicians to carry out these procedures will undermine their professional obligations and threaten the very goals of medicine. However, I maintain that the fundamental goals of medicine not only do not preclude the practice of euthanasia and assisted suicide by physicians, but can in fact be seen to support these practices in some instances. I look at two influential views (...) of the goals of medicine, one based on the broad guiding principles of autonomy, beneficence and nonmaleficence, and the other focusing on several more concrete aims, concluding that both approaches can be seen to support euthanasia and assisted suicide. I then turn to the popular concern that allowing physicians to carry out euthanasia and assisted suicide will lead to widespread abuse. I argue that the possibility for abuse can be minimised if we make the patient's autonomous consent an essential requirement of the practice. (shrink)

In my article "Controlling the noise," I present a phenomenological investigation of bodily experience in anorexia nervosa. Turning to descriptions of those who have suffered from AN, which repeatedly detail the experience of finding their bodies threatening, out of control and noisy, I suggest that the phenomenological conceptions of body-as-object, body-as-subject and visceral body can help us unpack the complex bodily experience of AN throughout its various stages. My claim is that self-starvation is enacted by a bodily-subject who wishes to (...) quell or reassert authority over a visceral body whose demands and needs she finds threatening to her autonomy.The relationship between body-as-object and...

Tinnitus is a common condition characterized by the perception of sound in the absence of an external source, with potential negative physical and psychological impacts. Accurate and efficient diagnosis of tinnitus is crucial for appropriate treatment and management. Traditional diagnostic methods have limitations in terms of time, cost, and accuracy. To address these challenges, expert systems have emerged as a promising tool for tinnitus diagnosis. This paper explores the application of expert systems in tinnitus diagnosis, highlighting their potential to improve (...) accuracy and efficiency. By incorporating a knowledge base and rule-based decision-making, expert systems can provide valuable insights for accurate diagnosis and appropriate management of tinnitus. Further research and development in this area can enhance the clinical assessment and treatment of tinnitus, ultimately improving the quality of life for affected individuals. (shrink)

Kant has a number of harsh-sounding things to say about beggars and giving to beggars. He describes begging as “closely akin to robbery”, and says that it exhibits self-contempt. In this paper I argue that on a particular interpretation of his political philosophy his critique of giving to beggars can be seen as part of a concern with social justice, and that his analysis makes sense of some troubling aspects of the phenomenology of being confronted with beggars. On Kant's view, (...) without absolute poverty relief, the poor persons' external freedom is subject to the arbitrary choices of those who have means. But the legitimacy of the state is based on ensuring that no one's basic freedom is subject to the arbitrary choices of another. This means that in a legitimate state public structures must ensure that there is unconditional poverty relief. Having your basic needs met through private charity wrongs you. Kant's analysis is that when you encounter someone in a public space who asks you for money to meet their basic survival needs, you are being asked to solve a public problem in a private interaction, and there is no rightful way for you to do this.
