The Bare Theory was offered by David Albert as a way of standing by the completeness of quantum mechanics in the face of the measurement problem. This paper surveys objections to the Bare Theory that recur in the literature: what will here be called the oddity objection, the coherence objection, and the context-of-the-universe objection. Critics usually take the Bare Theory to have unacceptably bizarre consequences, but to be free from internal contradiction. Bizarre consequences need not be decisive against the (...) Bare Theory, but a further objection—dubbed here the calibration objection—has been underestimated. This paper argues that the Bare Theory is not only odd but also inconsistent. We can imagine a successor to the Bare Theory—the Stripped Theory—which avoids the objections and fulfills the original promise of the Bare Theory, but at the cost of amplifying the bizarre consequences. The Stripped Theory is either a stunning development in our understanding of the world or a reductio disproving the completeness of quantum mechanics.

Research has probed the consequences of providing people with different types of information regarding why a person possesses a certain characteristic. However, this work has largely examined the consequences of different information subsets (e.g., information focusing on internal versus societal causes). Less work has compared several types of information within the same paradigm. Using the legal system as an example domain, we provided children (N=198 6- to 8-year-olds) with several types of information—including information highlighting internal moral character, internal biological factors, (...) behavioral factors, and societal factors—about why a specific outcome (incarceration) might occur. We examined how such language shaped children’s attitudes. In Study 1, children reported the most positivity toward people who were incarcerated for societal reasons and the least positivity toward people who were incarcerated for their internal moral character; attitudes linked with behavioral information fell between these extremes. Studies 2a-2b suggested that Study 1’s effects could not be fully explained by participants drawing different about individuals in Study 1. Study 3 replicated Study 1’s results and showed that information linking incarceration with internal biological factors led to more positivity than information linking incarceration with internal moral character. Finally, Study 4 suggested that the patterns found in Studies 1 and 3 generalize to non-punitive contexts. Moreover, Study 4 found that the effects in Studies 1 and 3 emerged regardless of whether information was communicated via explanations or descriptions. These results demonstrate that how we express our beliefs about social phenomena shape the realities in which others live. (shrink)

In one of the most unusual decisions in the history of legal publishing, Foundation Press is printing the 1958 "tentative edition" of Henry M. Hart, Jr. and Albert M. Sacks's teaching materials on The Legal Process: Basic Problems in the Making and Application of Law. Although The Legal Process remains unfinished to this day, it provided the agenda, much of the analytic structure, and even the name of the "legal process school" of the 1950s and the 1960s. One need (...) not embrace the proposition that The Legal Process is "the most influential book not produced in movable type since Gutenberg" to agree that these are unusually important teaching materials whose influence extends well beyond the students who studied them in a law school course.

Albert Einstein once made the following remark about "the world of our sense experiences": "the fact that it is comprehensible is a miracle." (1936, p. 351) A few decades later, another physicist, Eugene Wigner, wondered about the unreasonable effectiveness of mathematics in the natural sciences, concluding his classic article thus: "the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve" (1960, p. (...) 14). At least three factors are involved in Einstein's and Wigner's miracles: the physical world, mathematics, and human cognition. One way to relate these factors is to ask how the universe could possibly be structured in such a way that mathematics would be applicable to it, and we would be able to understand that application. This is roughly Wigner's question. Alternatively, the way of the mathematical naturalist is to argue that we abstract certain properties from the world, perhaps using our bodies and physical tools, thereby articulating basic mathematical concepts, which we continue building into the complex formal structures of mathematics. John Stuart Mill, Penelope Maddy, and Rafael Nuñez teach this strategy of cognitive abstraction, in very different manners. But what if the very concepts and basic principles of mathematics were built into our cognitive structure itself? Given such a cognitive a priori mathematical endowment, would the miracles of the link between world and cognition (Einstein) and mathematics and world (Wigner) not vanish, or at least significantly diminish? This is the stance of Stanislas Deheane and Elizabeth Brannon's 2011 anthology, following a venerable rationalist tradition including Plato and Immanuel Kant. (shrink)

The study aimed to analyze lexical items underpinned in the textbooks used in the current teaching of ESP and GE. Using content analysis, a systematic evaluation of texts to examine nuances to bridge the gap between quantitative and qualitative data. This was such of importance, however, difficult to study due to issues of interest like in the study, frequency of lexical items in ESP, and GE textbooks. Results found 13,713 lexical items in Hospitality Management, 17,561 in Criminology, 4576 in Tourism, (...) 7167 in Marine Engineering, and 512 in Information Technology. Furthermore, the overall percentage of ESP lexical items fell in Tier 2 (with multiple-meaning while the least was in Tier 3, specifically on context-specific vocabulary. It is the core of vocabulary learning to ensure English language teaching. It is its goal to help learners better understand language, allowing them to understand others as they want to express themselves as well. This applies not only in speaking but also in writing and reading. Wilkins (1972, p. 111-112) stated that without grammar very little understanding can be acquired and without vocabulary there can be no learning at all. Thus, even without good grammar, so long as you equipped with useful words and expression, one can still manage to communicate. Lewis (1993) argued that “lexis is the heart of language” and that it develops a better fluency and expression in English. He also added the significance to the learners of acquiring a more productive vocabulary knowledge, also, their eagerness to develop their own personal vocabulary strategies. Thus, a proposed bridge model program was recommended to highlight the study findings using the lexicons found from the different respective courses. (shrink)

A fundamental problem in science is how to make logical inferences from scientific data. Mere data does not suffice since additional information is necessary to select a domain of models or hypotheses and thus determine the likelihood of each model or hypothesis. Thomas Bayes’ Theorem relates the data and prior information to posterior probabilities associated with differing models or hypotheses and thus is useful in identifying the roles played by the known data and the assumed prior information when making inferences. (...) Scientists, philosophers, and theologians accumulate knowledge when analyzing different aspects of reality and search for particular hypotheses or models to fit their respective subject matters. Of course, a main goal is then to integrate all kinds of knowledge into an all-encompassing worldview that would describe the whole of reality. A generous description of the whole of reality would span, in the order of complexity, from the purely physical to the supernatural. These two extreme aspects of reality are bridged by a nonphysical realm, which would include elements of life, man, consciousness, rationality, mental and mathematical abstractions, etc. An urgent problem in the theory of knowledge is what science is and what it is not. Albert Einstein’s notion of science in terms of sense perception is refined by defining operationally the data that makes up the subject matter of science. It is shown, for instance, that theological considerations included in the prior information assumed by Isaac Newton is irrelevant in relating the data logically to the model or hypothesis. In addition, the concepts of naturalism, intelligent design, and evolutionary theory are critically analyzed. Finally, Eugene P. Wigner’s suggestions concerning the nature of human consciousness, life, and the success of mathematics in the natural sciences is considered in the context of the creative power endowed in humans by God.

TRANSPORTE DE GAMETAS, FERTILIZAÇÃO E SEGMENTAÇÃO -/- • _____OBJETIVO -/- O entendimento do desenvolvimento embrionário nos estágios iniciais, desde a deposição dos espermatozoides na fêmea, passando pela fertilização deste no ovócito e na formação do zigoto, é de suma importância para diferenciar especialistas em reprodução e manejo reprodutivo no mercado de trabalho e, também, durante a vida acadêmica. Compreender os processos que levam à formação do zigoto na fêmea é essencial para avaliar a capacidade reprodutiva dos animais e, mediante técnicas, (...) avaliar o trato reprodutivo da fêmea e o desenvolvimento do embrião até a formação do feto e, por fim, em um novo animal sadio na propriedade. Com esse trabalho, o estudante de veterinária ou zootecnia, que deseja se aprofundar na fisiologia da reprodução animal, identificará os mecanismos que são envolvidos no transporte dos gametas, bem como os processos que estes últimos devem completar para alcançar a fertilização e para desencadear as divisões iniciais do embrião. -/- • _____INTRODUÇÃO -/- A fertilização ou fecundação é o processo pelo qual os gametas masculino (espermatozoide) e feminino (ovócito) se fundem para gerar um novo indivíduo. Seu êxito depende da culminação adequada dos diferentes processos que devem sofrer os gametas durante sua maduração e percurso; do transporte oportuno destes no trato reprodutivo da fêmea, assim como de uma série de adaptações dos órgãos genitais internos da mãe. A segmentação refere-se às primeiras divisões celulares do embrião. -/- • _____TRANSPORTE DO OVÓCITO -/- O ovócito que é liberado na ovulação, e que se encontra coberto pelas células do cumulus (figura 1), é capturado pela fímbria do infundíbulo ao aderir aos cílios. Esse processo é altamente eficaz, inclusive em espécies onde os ovários possuem várias formações globosas, por exemplo nas porcas, onde os ovidutos capturam entre 95 e 100% dos ovócitos que são ovulados. As contrações das camadas musculares do oviduto e o movimento intenso dos cílios da mucosa faz com que as secreções fluam em direção ao útero, transportando assim o complexo cumulus-ovócito. Esse transporte é relativamente rápido até alcançar a junção da ampola com o istmo (que é considerado o local de fertilização do espermatozoide e ovócito) a partir do qual se torna lento. Devido a fêmea estar em estro, o processo está sob controle endócrino, isto é, controle hormonal através do estradiol. Nas fêmeas domésticas, ao contrário das mulheres, o transporte ao longo do oviduto é extremamente eficiente, pois os embriões passam para o útero sem dificuldade, de modo que gestações ectópicas (tubárias ou em cavidade) são quase inexistentes. A égua, frequentemente, retém por muito tempo os ovócitos não fertilizados no oviduto, provavelmente devido a não secreção de substâncias (como a prostaglandina E) que poderiam favorecer sua passagem, como se propõe que aconteça com os embriões. A figura 2 apresenta um ovócito com suas respectivas estruturas. Figura 1: ovócitos de uma vaca madurados in vitro. Nota-se as células do cumulus que os recobre. -/- Figura 2: estruturas do ovócito de uma ovelha que se encontra na etapa de ovócito secundário, depois da ovulação. Elaborado pelo autor. • _____TRANSPORTE ESPERMÁTICO -/- Para que os espermatozoides sejam capazes de fertilizar o ovócito, deverão sofrer uma série de mudanças bioquímicas e morfológicas ao longo de sua passagem pelo aparelho reprodutor tanto masculino como feminino. Uma vez produzidos na parede do túbulo seminífero, os espermatozoides são liberados em direção ao lúmen tubular e transportados passivamente para uma estrutura ramificada conhecida como rede testicular (rete testis). Dessa rede são conduzidos em direção ao epidídimo passando através de 10 a 20 ductos eferentes localizados no polo superior do testículo. O epidídimo é dividido em três seções denominadas cabeça, corpo e cauda; é constituído por um só ducto longo e tortuoso que continua com o canal deferente. Ao final desemboca nas ampolas seminais, no ducto ejaculatório e na uretra. As funções do epidídimo são as de maduração, transporte e armazenamento dos espermatozoides. O transporte através do epidídimo é lento, aproximadamente de 10 dias em touros, e segue sendo passivo. Os espermatozoides tomados da cabeça do epidídimo são ainda imaturos e incapazes de fertilizar, enquanto os armazenados na cauda são completamente maduros. Durante o trânsito pelo epidídimo os espermatozoides adquirem motilidade e o potencial para fertilizar, o acrossomo é remodelado e a gota citoplasmática migra para o flagelo e é liberada. Quando um macho ejacula com muita frequência, é possível observar espermatozoides com gota citoplasmática no sêmen, já que não há tempo suficiente para que completem sua maduração. Os espermatozoides são expulsados fora do organismo durante a cópula, na masturbação ou em emissões espontâneas. Na ejaculação, os espermatozoides que se encontram suspensos nos fluidos do testículo e do epidídimo, misturam-se ao chegar na uretra com as secreções das glândulas acessórias para formar o sêmen. Essas secreções denominadas plasma seminal, proporcionam substâncias para manter o metabolismo energético das células espermáticas, e integram suas membranas elementos que impedem uma capacitação prematura. Durante a cópula, o sêmen é depositado na vagina ou no útero, variando entre as espécies (tabela 1). Na monta natural, geralmente, o serviço ocorre no momento propício, já que está definido pela fase do ciclo estral em que a fêmea é receptiva ao macho. No entanto, na inseminação artificial, é o macho que deverá determinar o momento ideal, e para isso é importante considerar a vida média dos gametas, ao qual é muito curta no caso dos ovócitos (tabela 1). -/- Tabela 1: local de depósito do sêmen, volume da ejaculação e vida média dos gametas. Espécie Local de deposição Volume (ml) Velocidade de ejaculação Vida média do ovócito Vida média do espermatozoide Bovinos Intravaginal 2 1 – 3 seg 8 h 30 – 48 h Caninos Intravaginal 2 – 30 (10 média) 6 – 45 min 48 – 72 h 9 – 11 d Equinos Intrauterina 50 – 200 20 – 60 seg 6 – 8 h 72 – 120 h Humanos Intravaginal 3 - - 5 – 6 d Ovinos Intravaginal 1 1 – 2 seg 16 – 24 h 30 – 48 h Suínos Intrauterina 200 – 400 5 – 20 min 8 – 10 h 24 – 48 h Onde d = dias; h = horas. A vida fértil do ovócito é muito curta, portanto, o momento do serviço é de grande importância para obter altos índices de fertilização. -/- Independentemente do local em que os espermatozoides sejam depositados no aparelho reprodutor feminino, serão expostos às secreções genitais e sofrem uma série de mudanças em seu trajeto até o local de fertilização antes de penetrar no ovócito. Nas espécies em que o sêmen é depositado na parte cranial da vagina, uma parte do mesmo penetra através da cérvix, enquanto outra parte é eliminada do aparelho genital da fêmea, em pouco tempo, através do fluxo retrógrado. O meio vaginal não é adequado e imobiliza os espermatozoides em pouco tempo, pelo qual deverão entrar no útero onde o ambiente é mais propício. O transporte espermático na fêmea é o resultado da alta contratilidade, do movimento ciliar e o fluido do aparelho genital durante o estro, ao qual está sob controle endócrino e do sistema nervoso. Esse transporte é favorecido pelas características especiais do muco estral, cujas moléculas formam uma espécie de canais que facilitam a passagem dos espermatozoides. Pelo contrário, durante a fase lútea seu transporte é dificultado. Além do meio vaginal, a cérvix também atua como barreira natural para limitar a passagem dos espermatozoides, diminuindo assim a possibilidade de polispermia. Funciona, também, como um filtro que seleciona os espermatozoides aptos dos que não o são, uma vez que somente os primeiros possuem uma motilidade vigorosa que lhes permite passar pelo muco altamente hidratado. Na vaca a cérvix é considerada como um reservatório espermático. Quando atravessam a cérvix, os espermatozoides seguem sua deslocação tanto por movimento próprio como pelas contrações uterinas e tubárias. Nas espécies em que o local de depósito do sêmen do macho na fêmea é intrauterino, como equinos, a principal barreira que os espermatozoides enfrentam é a união ou junção útero-tubárica. A união entre o útero e o oviduto (istmo do oviduto) serve como reservatório funcional dos espermatozoides nas espécies domésticas. Poucos minutos depois da cópula, é possível encontrar alguns espermatozoides no oviduto, que é conhecido como fase de transporte rápido. No entanto, esses espermato-zoides não são os que participam do processo de fertilização e podem apresentar certas anormalidades. Existe um segundo tipo de transporte denominado fase sustentada, a qual consiste na migração prolongada dos espermatozoides em direção as partes mais craniais do aparelho genital feminino, que conduzem à colonização do reservatório funcional e na liberação gradual dos espermatozoides dos reservatórios espermáticos, incluindo este último. O reservatório do istmo fornece aos espermatozoides um ambiente propício, protegendo-os contra a fagocitose, prolongando assim a sua viabilidade. Aqui os esper-matozoides permanecem aderidos a superfície das células ciliadas do epitélio até a finalização de sua capacitação, depois da qual são liberados quando alteram seu padrão de motilidade flagelada, fenômeno conhecido como hipermotilidade, e migram em ondas em direção ao local da fertilização. Dos milhões de espermatozoides ejaculados, somente alguns milhares alcançarão o istmo do oviduto e um número sumamente pequeno será encontrado nas imediações do ovócito no momento da fertilização. -/- • _____CAPACITAÇÃO ESPERMÁTICA E REAÇÃO ACROSSÔMICA -/- A capacitação é um processo gradual e essencial para a fertilização. Os espermato-zoides devem passar por um dado tempo de “incubação” no aparelho genital da fêmea e sofrer uma série de mudanças antes de serem capazes de fecundar o ovócito. A capacita-ção dos espermatozoides começa quando eles entram em contato com as secreções do aparelho genital da fêmea e termina no istmo do oviduto. Durante esse percurso a superfície da cabeça do espermatozoide se modifica já que algumas moléculas como o colesterol são removidas da membrana plasmática, aumentando sua fluidez e alterando suas propriedades bioquímicas. Entre outras coisas, essa reorganização dos lipídios facilita a entrada de cálcio extracelular pelos canais iônicos e ocasiona a desestabilização da membrana, tornando-a mais fusogênica. Também são eliminados outros fatores (conhecidos genericamente como fatores descapacitantes) que expõem receptores membranais indispensáveis para a realização da união entre o espermatozoide e o ovócito durante a fertilização. Os espermatozoides capacitados apresentam um padrão de hipermotilidade e uma maior atividade metabólica, características que devem obter para que sejam capazes de penetrar as camadas do ovócito. A capacitação é necessária para que ocorra a reação acrossômica. A reação acrossomal ou acrossômica (RA) é um fenômeno de exocitose que é desencadeada pela ligação entre as proteínas e receptores localizados na membrana do espermatozoide e a zona pelúcida do ovócito (figura 3). Envolve a fusão da membrana plasmática do espermatozoide com a membrana externa de seu acrossomo; formando, assim, pequenas vesículas, cujo conteúdo de enzimas hidrolíticas, como a hialuronidase e a acrosina, é liberado em direção ao seu exterior, facilitando a penetração da zona pelúcida. A adesão do espermatozoide à zona pelúcida é específica da espécie e depende de glicoproteínas presentes na membrana dos ovócitos maduros; a cabeça do espermatozoide se une com essas glicoproteínas mediante receptores específicos e atravessam em direção oblíqua a zona pelúcida até chegar ao espaço perivitelino. Nos mamíferos, particularmente em roedores e nos humanos, algumas dessas glicoproteínas são conhecidas como ZP1, ZP2 e ZP3. Pensa-se que a união da membrana espermática a esta última é o que desencadeia a reação acrossomal. Posteriormente, as vilosidades do ovócito entram em contato com o espermatozoide e a membrana presente na secreção equatorial da cabeça do espermatozoide, que tem proteínas fusogênicas específicas, une-se a membrana plasmática do ovócito, fusionando-se e permitindo a entrada do núcleo espermático ao citoplasma (figura 4). A capacitação dos espermatozoides é fundamental para o êxito da fertilização, uma vez que apenas os aptos estarão perfeitos e íntegros para que a união e percepção das glicoproteínas presentes nos mesmos possam ocorrer de forma ideal para a penetração deste no ovócito, fertilizá-lo e formar um zigoto. Figura 3: estrutura do espermatozoide. Nota: a membrana é acrossomal e não acrossonal. Elaborado pelo autor. -/- Figura 4: eventos que ocorrem durante a fertilização. A – depois de passar através das células do cumulus, o espermatozoide entra em contato com a zona pelúcida, onde receptores da membrana plasmática reconhecem as proteínas da zona pelúcida; B – é desencadeada, então, a reação acrossomal; C – para que o espermatozoide penetre na zona pelúcida; D – ao atravessar a zona pelúcida e entrar no espaço perivitelino, a cabeça do espermatozoide entra em contato com a membrana vitelina; ambas membranas se fusionam graças ao reconhecimento de proteínas fusogênicas que estão no segmento equatorial. E – ocorre, então, que o núcleo do espermatozoide penetra no citoplasma do ovócito; uma das consequências da fusão da membrana com a cabeça do espermatozoide é a reação cortical, em que os grânulos corticais do ovócito liberam seu conteúdo em direção ao espaço perivitelino, o que resulta na alteração da estrutura da zona pelúcida e da membrana vitelina para bloquear a polispermia. Elaborado pelo autor. • _____CONSEQUÊNCIAS DA PENETRAÇÃO -/- Bloqueio da polispermia -/- A fusão das membranas dos gametas durante a penetração permite a entrada da fosfolipase C zeta (PLCζ) – fator solúvel que provém do espermatozoide – que desencadeia liberação e oscilações de Ca2+ no retículo endoplasmático. Isso, por sua vez, provoca a migração e fusão dos grânulos corticais, com a consequente liberação de enzimas, que mudam tanto a estrutura da zona pelúcida (por exemplo a inativação de ZP3), como a da membrana vitelina. Desse modo, impede-se que outros espermatozoides as penetrem, evitando assim a polispermia (figura 5). -/- Figura 5: os grânulos corticais que encontram-se na periferia do citoplasma, debaixo da superfície da membrana do ovócito, migram e fusionam-se sobre a mesma, liberando seu conteúdo no espaço perivitelino imediatamente depois da penetração do espermatozoide. A – como conse-quência, tanto a membrana vitelina como a zona pelúcida são modificadas, impedindo a entrada de mais espermatozoides, o que evita a polispermia. B – o ovócito retoma, então, sua segunda divisão meiótica, que ocasiona a expulsão do segundo corpúsculo polar, e na formação dos pronúcleos feminino e masculino. C – continuando, os pronúcleos migram, suas membranas se dissolvem e os cromossomos de ambos se condensam e se unem. Completa-se, assim, a singamia e forma-se, então, o zigoto. Elaborado pelo autor baseado nos livros de embriologia e fisiologia da reprodução conforme vida bibliografia. -/- Ativação do ovócito e formação de pronúcleos -/- Na maioria das fêmeas domésticas, com exceção da cadela, o ovócito encontra-se suspenso na metáfase II da segunda meiose no momento da ovulação. A entrada da PLCζ do espermatozoide no citoplasma do ovócito, e a consequente liberação de Ca2+, faz com que o ovócito se ative, terminando a segunda divisão meiótica e expulse o segundo corpo polar. Posteriormente, o material nuclear do ovócito se reorganiza para formar o pronú-cleo feminino. Entretanto, a membrana nuclear do espermatozoide se dissolve, a cromatina descondensa-se, as protaminas são substituídas por histonas, e se forma uma nova membrana nuclear, dando lugar ao pronúcleo masculino. -/- Singamia -/- Uma vez que os pronúcleos feminino e masculino são formados, migram para o centro do ovócito, aproximam-se, suas membranas se dispersam e os cromossomos paternos e maternos se associam, com o qual recupera a condição diploide e dá origem ao zigoto (figura 5). -/- • _____DESENVOLVIMENTO EMBRIONÁRIO -/- Poucas horas após a fertilização ocorre a primeira divisão do zigoto em duas, depois em 4, 8, 16 e 32 células, denominadas blastômeros. Essas divisões mitóticas são conhecidas como divisões de segmentação ou clivagem (figura 6), uma vez que são realizadas sem aumento do citoplasma, de modo que com cada divisão os blastômeros se tornam menores. A partir das 16 células o embrião se chama mórula, e é visto como uma massa celular compacta. A compactação deve-se a informação de proteínas de ligação entre os blastômeros. O embrião acumula líquido em seu interior, formando uma cavidade denominada blastocele. Esse processo é conhecido como blastulação; o embrião, assim, passa a ser chamado de blastocisto. Nessa etapa é possível diferenciar duas populações de células embrionárias: a massa celular interna, embrioblasto ou botão embrionário (que dará origem ao embrião), e a massa celular externa, células superficiais ou trofoblasto, do qual se originam a maioria das membranas fetais. Ao continuar a multiplicação das células e a acumulação de líquido, o blastocisto aumenta de tamanho, convertendo-se em blastocisto expandido. A zona pelúcida torna-se mais fina e, finalmente, o embrião eclode; isto é, o embrião é liberado da zona pelúcida. -/- • _____FERTILIZAÇÕES ATÍPICAS -/- Polispermia -/- É a penetração de dois ou mais espermatozoides no óvulo. Esta condição é letal nos mamíferos, já que o número cromossômico desse zigoto é maior que 2n, o envelheci-mento do ovócito da porca, como consequência do serviço tardio, favorece a apresentação da polispermia, por isso, é comum ver números de nascimentos de média de 10 a 12 leitões por parição nessa espécie. Nas aves, no entanto, a penetração de mais de um espermatozoide é normal, embora apenas um pronúcleo masculino se formará, fundindo-se com o feminino. -/- Figura 6: etapas do processo de segmentação/clivagem. Fonte: aula de reprodução da professora Domenica Palomaris, UFT. -/- Ginogênese -/- É o desenvolvimento de um embrião a partir de um óvulo normal fecundado por um espermatozoide, mas sem a fusão dos cromossomos masculinos com os da fêmea. A função do espermatozoide, nesse caso, é a de ativação do ovócito para que este inicie seu desenvolvimento, mas não há fusão com o núcleo do espermatozoide. Ocorre em plantas, em nematódeos e em algumas espécies de peixes, por exemplo a Poecilia formosa, espécie em que os ovócitos das fêmeas são ativados por machos de outra espécie relacio-nada. -/- Partenogênese -/- Consiste no desenvolvimento do embrião sem a participação do espermatozoide. Ocorre em alguns insetos, o zangão, por exemplo, é partenogenético. Também pode apresentar-se em perus, cujos embriões são machos e, geralmente, morrem antes da eclosão. -/- • _____GÊMEOS -/- Existem dois tipos de gêmeos: idênticos ou monozigóticos e os não idênticos ou dizigóticos. -/- Idênticos ou monozigóticos -/- Originam-se do mesmo zigoto, sendo assim, possuem o mesmo genótipo e um fenótipo similar e, portanto, são do mesmo sexo. Em laboratório é possível gerá-los ao seccionar uma mórula em duas ou mais partes, por meio de um micromanipulador. Uma vez que possuem o mesmo genótipo, os produtos resultantes são clones. -/- Não idênticos ou dizigóticos -/- Provêm da fertilização de dois óvulos distintos por espermatozoides diferentes. Possuem, portanto, genótipos e fenótipos diferentes, e podem ser de sexo diferente. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- ALBERTS, Bruce et al. Biologia molecular da célula. Artmed Editora, 2010.

This interview continues Albert Efimov’s series of discussions with scholars about the current state of artificial intelligence, its applications across various fields and tasks, and the ethical and social implications of its development. In the conversation regarding humanity’s place in the modern world, A.G. Asmolov discussed the importance of maintaining diversity within complex systems and managing complexity during their analysis. The dialogue clarified the role of the «contrarian,» the future anthropologist’s work, and how metaphor will drive scientific progress in (...) the age of artificial intelligence. Additional topics addressed include: the significance of tricksters in the search for new ideas and meanings; the reasons we condemn ourselves to a lack of free time and its impact on cognitive abilities; the mismatch between organizational structures created by humans and the levels of tasks and technologies emerging today; the core concepts underlying «human-centric organizations»; whether the development of artificial intelligence will lead to information asymmetry, where everyone knows everything, and the primary risks when humans begin to learn from machines; why AI developers can be seen as a «community of Pygmalions,» and the dangers of «humanizing» machines.

In Necessary Beings, Bob Hale addresses two questions: What is the source of necessity? What is the source of our knowledge of it? He offers novel responses to them in terms of the metaphysical notion of nature or, more familiarly, essence. In this paper, I address Hale’s response to the first question. My assessment is negative. I argue that his essentialist explanation of the source of necessity suffers from three significant shortcomings. First, Hale’s leading example of an essentialist explanation merely (...) asserts that the nature of an entity explains some necessity, but leaves unexplained how it does so. Second, his essentialist explanation of particular necessities introduces new necessities that remain unexplained. Third, Hale’s version of essentialism presupposes a controversial metaphysical theory of properties, for which he offers no defense. (shrink)

Rationalists often argue that empiricism is incoherent and conclude, on that basis, that some knowledge is a priori. I contend that such arguments against empiricism cannot be parlayed into an argument in support of the a priori since rationalism is open to the same arguments. I go on to offer an alternative strategy. The leading idea is that, instead of offering a priori arguments against empiricism, rationalists should marshal empirical support for their position.

Russians and Westerners access, process and communicate information in different ways. Whilst Westerners favour detailed analysis of subject matter, Russians tend to focus on certain components that are, in their view, significant. This disparity makes it difficult to achieve constructive dialogues between Western and Russian stakeholders contributing to cross-cultural communication problems. The author claims that the difference in the ways Russians and Westerners negotiate information is a significant cultural difference between Russia and West rather than an irritating (and in principle (...) amenable) lack of analytical skills on the Russian partners’ part. Understanding the reasons behind the Russian-specific approaches to dealing with information would be a positive step towards a more effective cross-cultural communication, important in business situations and essential in diplomacy.

In this paper, I critically assess different interpretations of Bohmian mechanics that are not committed to an ontology based on the wave function being an actual physical object that inhabits configuration space. More specifically, my aim is to explore the connection between the denial of configuration space realism and another interpretive debate that is specific to Bohmian mechanics: the quantum potential versus guidance approaches. Whereas defenders of the quantum potential approach to the theory claim that Bohmian mechanics is better formulated (...) as quasi-Newtonian, via the postulation of forces proportional to acceleration; advocates of the guidance approach defend the notion that the theory is essentially first-order and incorporates some concepts akin to those of Aristotelian physics. Here I analyze whether the desideratum of an interpretation of Bohmian mechanics that is both explanatorily adequate and not committed to configuration space realism favors one of these two approaches to the theory over the other. Contrary to some recent claims in the literature, I argue that the quasi-Newtonian approach based on the idea of a quantum potential does not come out the winner. (shrink)

In medical ethics, business ethics, and some branches of political philosophy (multi-culturalism, issues of just allocation, and equitable distribution) the literature increasingly combines insights from ethics and the social sciences. Some authors in medical ethics even speak of a new phase in the history of ethics, hailing "empirical ethics" as a logical next step in the development of practical ethics after the turn to "applied ethics." The name empirical ethics is ill-chosen because of its associations with "descriptive ethics." Unlike descriptive (...) ethics, however, empirical ethics aims to be both descriptive and normative. The first question on which I focus is what kind of empirical research is used by empirical ethics and for which purposes. I argue that the ultimate aim of all empirical ethics is to improve the context-sensitivity of ethics. The second question is whether empirical ethics is essentially connected with specific positions in meta-ethics. I show that in some kinds of meta-ethical theories, which I categorize as broad contextualist theories, there is an intrinsic need for connecting normative ethics with empirical social research. But context-sensitivity is a goal that can be aimed for from any meta-ethical position. (shrink)

As indicated in the title this article is a brief description of the body, soul and spirit of man, based on the divine revelations received by the Austrian mystic Jakob Lorber between 1840 and 1864. While it is common knowledge that man has a body and a soul, very little is known about the spirit in man which is the primary source of knowledge and power, penetrating both the soul and body.

Although the index is one of the best known features of Peirce's theory of signs there is little appreciation of Peirce's theory of the index amongst contemporary philosophers of language. Amongst Peirce scholars, the value placed on Peirce's account is greater, but is largely based on Thomas Goudge's paper, "Peirce's Index" (Goudge, 1965). Despite marking a crucial milestone in our comprehension of Peirce's theory, our understanding of indices and indexical reference has grown markedly over the last forty years. Time has (...) now come, then, to develop the work that Goudge began and to provide a full analysis of Peirce's account that makes its value to the philosophy of language clear. I undertake this enterprise here. (shrink)

This paper focuses on coherence and consistency as elements of moral integrity, arguing that several kinds of—mostly second-order—virtues contribute to establishing coherence and consistency in a person's judgements and behaviour. The virtues relevant for integrity always accompany other, substantive virtues, and their associated values, principles and rules. In moral education we teach children all kinds of substantive virtues with integrity as our goal. Nevertheless, many adults do not attain moral integrity, although they are clearly not immoral. What precisely are they (...) lacking? Education for moral integrity should focus on strengthening motivational self-sufficiency, furthering critical and imaginative thinking and promoting moral unity. (shrink)

Albert Musschenga | : The central question of this article is, Are animals morally responsible for what they do? Answering this question requires a careful, step-by-step argument. In sections 1 and 2, I explain what morality is, and that having a morality means following moral rules or norms. In sections 3 and 4, I argue that some animals show not just regularities in their social behaviour, but can be rightly said to follow social norms. But are the norms they (...) follow also moral norms? In section 5, I contend, referring to the work of Shaun Nichols, that the basic moral competences or capacities are already present in nonhuman primates. Following moral rules or norms is more than just acting in accordance to these norms; it requires being motivated by moral rules. I explain, in section 6, referring to Mark Rowlands, that being capable of moral motivation does not require agency; being a moral subject is sufficient. Contrary to moral agents, moral subjects are not responsible for their behaviour. Stating that there are important similarities between animal moral behaviour and human, unconscious, automatic, habitual behaviour, I examine in section 7 whether humans are responsible for their habitual moral behaviour, and if they are, what then the grounds are for denying that moral animals are responsible for their behaviour. The answer is that humans are responsible for their habitual behaviour if they have the capacity for deliberate intervention. Although animals are capable of intervention in their habitual behaviour, they are not capable of deliberate intervention. | : La question centrale dans cet article est celle de savoir si les animaux sont moralement responsables de ce qu’ils font. Répondre à cette question nécessite une argumentation minutieuse et progressive. Dans les sections 1 et 2, j’explique ce qu’est la moralité, et qu’être doté de moralité signifie de se conformer à des règles ou à des normes morales. Dans les sections 3 et 4, je pose que certains animaux ne se contentent pas de montrer des régularités dans leur comportement social, mais qu’ils suivent aussi véritablement des normes sociales. Toutefois, les normes qu’ils suivent sont-elles morales? Dans la section 5, je prétends, en me référant aux travaux de Shaun Nichols, que les compétences ou capacités morales de base sont déjà présentes chez les primates non humains. Respecter des règles ou des normes morales est bien plus que d’agir conformément à ces normes; cela requiert d’être motivé par des règles morales. Dans la section 6, me référant à Mark Rowlands, j’explique que d’être capable de motivation morale ne nécessite pas d’être un agent moral; le fait d’être un sujet moral suffit. Contrairement aux agents moraux, les sujets moraux ne sont pas responsables de leur comportement. Affirmant qu’il y a de grandes similitudes entre le comportement moral d’un animal et le comportement inconscient, automatique et habituel d’un humain, je me penche, dans la section 7, sur la question de savoir si les humains sont responsables de leur comportement moral habituel, et si tel est le cas, sur quelle base on peut alors nier le fait que les animaux sont eux aussi responsables de leur comportement. La réponse à cette question est que les humains sont responsables de leur comportement habituel s’ils disposent d’une capacité d’intervention réfléchie, délibérée. Bien que les animaux soient capables d’intervenir dans leurs comportements habituels, ils ne peuvent le faire de manière réfléchie, délibérée. (shrink)

In this article, I discuss whether intuitive moral judgements have epistemic value. Are they mere expressions of irrational feelings that should be disregarded or should they be taken seriously? In section 2, I discuss the view of some social psychologists that moral intuitions are, like other social intuitions, under certain conditions more reliable than conscious deliberative judgements. In sections 3 and 4, I examine whether intuitive moral judgements can be said not to need inferential justification. I outline a concept of (...) moral intuition as a seeming whose seemingness resides in special, phenomenological features such as a felt veridicality, appropriateness, familiarity, or confidence, and whose justificatory force is influenced by the reliability of the belief-producing procedures and by a subject's competence in applying moral concepts. I argue that subjects can come to realise that the beliefs expressed in their intuitive judgements evoke a sense of non-inferential credibility. In section 5, I first discuss the contribution of moral expertise to the non-inferential credibility of a person's intuitions. Subsequently, I discuss whether Walter Sinnott-Armstrong is right in saying that we can never claim non-inferential justification for our intuitions because they are subject to all kinds of distorting influences.

Amongst the many social factors that impact upon children, race is arguably one of the largest. Race is an ever-present social category that governs many elements of a child’s interaction with others, and especially for racial minority children it exerts a deep influence on their understanding of themselves. In this chapter, we shall begin by examining what the concept of race really amounts to, emphasizing its status as a socially constructed concept, before examining in the following section how children first (...) come to recognize the existence of race, and to understand their own racial identity.We will then look at two important areas that illustrate the profound impact that the social presence of race and the child’s developing understanding of racial identity have upon the social conditions of many children. First, we will examine how race and childhood intersect in matters of educational opportunity and achievement, before moving on to examine the issue of transracial adoption in the final section.

Debates over the reality of race often rely on arguments about the connection between race and science—those who deny that race is real argue that there is no significant support from science for our ordinary race concepts; those who affirm that race is real argue that our ordinary race concepts are supported by scientific findings. However, there is arguably a more fundamental concern here: How should we define race concepts in the first place? The reason I claim that this definitional (...) question is more fundamental is that our handling of the underlying definitional problem often determines the scientific support our ordinary race concepts need, and importantly the likelihood of finding such support. In short, the defini- tional question, “How do we define race?” often undercuts the question of whether race is scientifically meaningful. (shrink)

Gerade weil das Bestehen auf Rangordnungen in der heutigen Gesellschaft anstößig und fremd wirkt, ist es lohnenswert, sich ihnen mit Nietzsche neu zu stellen, der sie als sein Problem bezeichnete. Er richtet sie gezielt gegen die Gleichheit, von der er befürchtet, ihr Anspruch auf Universalität verunmögliche Individualität, Anders-Sein und damit auch alle Größe. Den moralischen Wert der Gleichheit kritisieren heißt nicht, sich von demokratischen Grundprinzipien oder Errungenschaften zu verabschieden. Geklärte Rangverhältnisse reduzieren Komplexität, vereinfachen die Kommunikation, machen Verhalten erwartbar und vereinfachen (...) so die Orientierung. So könnte gerade in den modernen Ausprägungen der Demokratie ein offenerer Umgang mit Rangordnungen zu ihrer Stärkung beitragen. Die Nietzsche-Forschung hat eine Beschäftigung mit dem Begriff bisher weitgehend vermieden. Alberts schließt diese Forschungslücke. Er geht persönlichen, philologischen und philosophischen Anhaltspunkten für Nietzsches Denken nach und untersucht die Perspektiven, die dabei auf verschiedenste Lebensbereiche wie Natur, Religion, Moral, Wissenschaft und Interindividualität eröffnet werden.

In this paper I examine parallels between C.S. Peirce's most mature account of signs and contemporary philosophy of language. I do this by first introducing a summary of Peirce's final account of Signs. I then use that account of signs to reconstruct Peircian answers to two puzzles of reference: The Problem of Cognitive Significance, or Frege's Puzzle; and The Same-Saying Phenomenon for Indexicals. Finally, a comparison of these Peircian answers with both Fregean and Direct Referentialist approaches to the puzzles highlights (...) interesting parallels and important differences between Peirce's final account of signs, and the concepts used in analytic philosophy of language.

The study of race and racism is an area of growth in philosophy. The quantity of research published under the banner of ‘the philosophy of race’ is increasing; research monographs and edited collections are appearing in greater numbers, and there is even a noticeable though still lamentably small increase in the number of professional posi- tions being advertised in the philosophy of race. However, one notable feature of this research is how much it focuses upon the racial context of the (...) USA. Most of its active and prominent researchers are based in the USA, nearly all new posts with designated research specialisms in race are at universities in the USA, and most of its key research questions are framed in the racial idiom and social context of the contemporary USA. In many respects, this is a good thing: if the philosophy of race cannot find fertile ground in the USA, there is little hope of it flourishing anywhere. However, this emphasis on the US context may have a negative side too. (shrink)

In this article I examine the consequences of the dominance of intuitive thinking in moral judging and deciding for the role of moral reasoning in moral education. I argue that evidence for the reliability of moral intuitions is lacking. We cannot determine when we can trust our intuitive moral judgements. Deliberate and critical reasoning is needed, but it cannot replace intuitive thinking. Following Robin Hogarth, I argue that intuitive judgements can be improved. The expertise model for moral development, proposed by (...) Hubert and Stuart Dreyfus, not only teaches us how we acquire intuitive moral judgements, it also shows the interconnectedness of intuitive thinking and deliberate reasoning. Analysing the expertise model in more detail, I show that it cannot do justice to the importance of reasoning skills. Reasoning skills are needed because we expect people to be able to argue for their standpoints. I conclude that moral education should not only aim at improving intuitive moral judgements, but also at acquiring reasoning skills. (shrink)

This paper addresses a family of issues surrounding the biological phenomenon of resistance and its representation in realist ontologies. The treatments of resistance terms in various existing ontologies are examined and found to be either overly narrow, internally inconsistent, or otherwise problematic. We propose a more coherent characterization of resistance in terms of what we shall call blocking dispositions, which are collections of mutually coordinated dispositions which are of such a sort that they cannot undergo simultaneous realization within a single (...) bearer. A definition of ‘protective resistance’ is proposed for use in the Infectious Disease Ontology (IDO) and we show how this definition can be used to characterize the antibiotic resistance in Methicillin-Resistant Staphylococcus aureus (MRSA). The ontological relations between entities in our MRSA case study are used alongside a series of logical inference rules to illustrate logical reasoning about resistance. A description logic representation of blocking dispositions is also provided. We demonstrate that our characterization of resistance is sufficiently general to cover two other cases of resistance in the infectious disease domain involving HIV and malaria. (shrink)

This article offers comprehensive criticism of the Turing test and develops quality criteria for new artificial general intelligence (AGI) assessment tests. It is shown that the prerequisites A. Turing drew upon when reducing personality and human consciousness to “suitable branches of thought” re-flected the engineering level of his time. In fact, the Turing “imitation game” employed only symbolic communication and ignored the physical world. This paper suggests that by restricting thinking ability to symbolic systems alone Turing unknowingly constructed “the wall” (...) that excludes any possi-bility of transition from a complex observable phenomenon to an abstract image or concept. It is, therefore, sensible to factor in new requirements for AI (artificial intelligence) maturity assessment when approaching the Tu-ring test. Such AI must support all forms of communication with a human being, and it should be able to comprehend abstract images and specify con-cepts as well as participate in social practices. (shrink)

Migrating legacy database applications to modern cloud-based solutions, such as Snowflake, is becoming essential for organizations aiming to leverage scalable, efficient, and cost-effective data solutions. Legacy databases, typically bound to on-premises infrastructure, often lack the flexibility required by contemporary data analytics and storage needs. Snowflake, a cloud-native data platform, provides a versatile environment that enables efficient data storage, sharing, and processing. This research examines a structured methodology for migrating legacy database applications to Snowflake, addressing key stages from initial assessment to (...) data transformation, integration, and performance optimization. A systematic, step-by-step migration process is implemented to minimize risks, reduce downtime, and ensure data integrity. (shrink)

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

In my paper, I develop a phenomenological and pragmatist reflection on the fragility of liberal democracy’s moral foundations in times of war. Following Judith Shklar’s conception of the “liberalism of fear”, the legitimacy of the liberal-democratic order is seen as grounded in experiences of suffering caused by political violence. It is also assumed that the liberalism of fear delivers an adequate conception of the normative foundations of the European project. With the help of phenomenologists such as Edmund Husserl, Maurice Merleau-Ponty (...) and Michel Henry, the paper ants to philosophically deepen the liberalism of fear by outlining a theory of “pathic evidence” as a normative foundation and the concept of a common “flesh of the political” as a shared moral sensitivity that sets boundaries to political conflict as well as the political imaginary, excluding what I call the production of “monumental meaning”. It then examines the question which political conditions are needed for this evidence to become a shared, communal criteria of ethical thought, and considers inner and outer challenges to the transmission and reproduction of this evidence in time, drawing especially on John Dewey’s ideas of democratic communication and social intelligence. In the current war, the following problem appears as crucial for the “soul” of European democracies which are confronted with the need to respond to Russia’s attack: How can a political morality grounded in pathic evidence be sustained, once it is challenged by an aggressor who, out of cultural and political reasons, shows a higher level of toleration towards violence? Besides aggression from an external foe, there are also temporal dynamics that further the loss of the inhibiting force of pathic evidence from the inside. As it shall be argued, boredom can be such a factor. The paper concludes by drawing conclusions for the current war in Ukraine. (shrink)

Cloud storage's scalability, accessibility, and affordability have made it essential in the digital age. Data security and privacy remain a major issue due to the large volume of sensitive data kept on cloud services. Traditional encryption is safe but slows data recovery, especially for keyword searches. Secure, fine-grained access control and quick keyword searches over encrypted data are possible using attribute-based keyword search (ABKS). This study examines how ABKS might optimize search efficiency and data security in cloud storage systems. We (...) examine index compression, query processing improvement, and encryption optimization to decrease computational cost and preserve security. (shrink)

This paper addresses the use of dispositions in the Infectious Disease Ontology (IDO). IDO is an ontology constructed according to the principles of the Open Biomedical Ontology (OBO) Foundry and uses the Basic Formal Ontology (BFO) as an upper ontology. After providing a brief introduction to disposition types in BFO and IDO, we discuss three general techniques for representing combinations of dispositions under the headings blocking dispositions, complementary dispositions, and collective dispositions. Motivating examples for each combination of dispositions is given (...) along with a specific use case in IDO. Description logic restrictions are used to formalize statements relating to these combinations. (shrink)

Pragmatist approaches to truth have often been judged in light of a caricature of William James’ claim that, “the ‘true’ is only the expedient in our way of thinking”. This unfortunate caricature, where truth is claimed to be ‘whatever it’s useful to believe’, means pragmatist theories of truth are generally seen as non-starters, or unworthy of serious attention. And even leaving aside stalking-horse versions of classical pragmatism, there is also a view that whatever contemporary pragmatists have been doing with ‘truth’ (...) it bears little resemblance to the projects that concern analytic philosophers. For example, Rorty’s frequent exhortations for pragmatists to turn their back on truth and look... (shrink)

According to some proponents of an empirical medical ethics, medical ethics should take the experience, insights, and arguments of doctors and other medical practitioners as their point of departure. Medical practitioners are supposed to have ‘moral wisdom.’ In this view, the moral beliefs of medical practitioners have a special status. In sections I-IV, I discuss two possible defences of such a status. The first defence is based on the special status of the moral beliefs of the health professional as an (...) expert in medical ethics, and the second defence on the special status of the health professional’s moral beliefs as a practitioner. The first defence is built up around the opposition between experts and laypersons, while the second defence rests on the opposition between practitioners and theorists. In sections V and VI, I examine the interrelations between empirical ethics and anti-theory in ethics. Some regard empirical ethics as a laudable alternative to theory-driven normative ethics. I explore their objections against ethical theory and ethical theorising, and conclude that they are not valid. In the last section, VII, I discuss the role of ethicists in medical practice.

This research explored the utilization of video-based instructional material in enhancing learning competency among a group of sixty (60) students enrolled in grade 8 at Satriwithaya School in Bangkok, Thailand. The study was carried out. out during the 2nd semester of S.Y. 2023–2024. The respondents were chosen using the approach of purposive sampling. The research study employed an experimental approach and utilized quantitative research. Through the use of of a one-group pre- and post-test, the researcher was able to gather the (...) necessary data. The study included statistical measures such as percentages, means, and standard deviations, as well as dependent and independent t-tests, to assess and compare the proficiency and efficacy of utilizing video-based educational materials among students at Satriwithaya School in Bangkok, Thailand. Study findings also revealed that there is a significant difference in pre- and post-test assessment scores before and after using the video-based instructional materials. The research outcomes indicated that the application of video-based teaching resources as an instructional strategy in the field of biology resulted in an increased degree of effectiveness in the students' learning process. The findings of the study suggest that the utilization of video-based instructional materials has favorable outcomes in terms of enhancing pedagogical and educational achievements in the field of biology. This methodology has been demonstrated to provide learners with with the chance to enhance their comprehension through active participation, cultivate their imagination and cleverness, consequently facilitating enhanced educational achievements. Furthermore, the establishment of a conducive learning atmosphere that is both engaging and pleasurable for students can enhance their overall learning experience. Moreover, this approach enhances the teacher's capacity to convey their intended educational objectives to their students proficiently. -/- . (shrink)

A. Efimov, D. Dubrovsky, and F. Matveev explore limitations on the development of AI presented by the need to understand language and be embodied.

There is an ongoing debate in animalethics on the meaning and scope of animalwelfare. In certain broader views, leading anatural life through the development of naturalcapabilities is also headed under the conceptof animal welfare. I argue that a concern forthe development of natural capabilities of ananimal such as expressed when living freelyshould be distinguished from the preservationof the naturalness of its behavior andappearance. However, it is not always clearwhere a plea for natural living changes overinto a plea for the preservation (...) of theirnaturalness or wildness. In the first part ofthis article, I examine to what extent theconcerns for natural living meet ``theexperience requirement.'' I conclude that someof these concerns go beyond welfare. In thesecond part of the article. I ask whether wehave moral reasons to respect concernsfor the naturalness of an animal's living thattranscend its welfare. I argue that the moralrelevance of such considerations can be graspedwhen we see animals as entities bearingnon-moral intrinsic values. In my view the``natural'' appearance and behavior of an animalmay embody intrinsic values. Caring for ananimal's naturalness should then be understoodas caring for such intrinsic values. Intrinsicvalues provide moral reasons for action iffthey are seen as constitutive of the good lifefor humans. I conclude by reinterpreting,within the framework of a perfectionist ethicaltheory, the notion of indirect dutiesregarding animals, which go beyond andsupplement the direct duties towardsanimals.

A repository of clinically associated Staphylococcus aureus (Sa) isolates is used to semi‐automatically generate a set of application ontologies for specific subfamilies of Sa‐related disease. Each such application ontology is compatible with the Infectious Disease Ontology (IDO) and uses resources from the Open Biomedical Ontology (OBO) Foundry. The set of application ontologies forms a lattice structure beneath the IDO‐Core and IDO‐extension reference ontologies. We show how this lattice can be used to define a strategy for the construction of a new (...) taxonomy of infectious disease incorporating genetic, molecular, and clinical data. We also outline how faceted browsing and query of annotated data is supported using a lattice application ontology. (shrink)

The study examines the argumentative competencies of people with Asperger syndrome (AS) and compares this with those of normal – or what are called neurotypical (NT) – subjects. To investigate how people with AS recognise, evaluate and engage in argumentation, we have adapted and applied the empirical instrument developed by van Eemeren, Garssen and Meuffels to study the conventional validity of the pragma-dialectical freedom rule (van Eemeren, Gars- sen & Meuffels 2003a; 2003b; 2005a; 2005b; van Eemeren & Meuffels, 2002). Our (...) paper begins with some background information on Asperger syndrome and how it impacts upon communication and argumentation; then it addresses the research questions and methods used; thirdly, it presents some initial findings; finally, it will conclude with some im- plications for those people with AS, for those they come into contact with and for the pragma-dialectic model in general.

Der vorliegende Forschungsband möchte der kulturelle Bedeutung der Ersten Republik und deren Leistungen einen gebührenden Platz einräumen. Während sich nämlich Wiener Moderne und Weimarer Republik heute einer fortdauernden Aufmerksamkeit erfreuen, sind die Kultur der Ersten Republik und hier vorab des soziokulturellen Laboratoriums Wien – vermutlich schon in der Wahrnehmung vieler Zeitgenossinnen und Zeitgenossen unterbelichtet geblieben. Versammelt sind Beiträge zur Volksbildung im Roten Wien, zu Architektur und Stadtplanung, zu neuen Diskursen in der Psychoanalyse oder zur Neuorientierung Musils nach 1918, die später (...) zu seinem epochalen Roman »Der Mann ohne Eigenschaften« führen wird. Was ihn von anderen Publikationen unterscheidet, ist ein komparatistischer Aspekt, der etwa im Vergleich zwischen der Revolution 1918 in Wien und Österreich und der (kurzlebigen) Räterepublik in Ungarn aber auch in der Analyse der ungarischen Medien in der Zwischenkriegszeit zum Ausdruck kommt. Durch diese erhellenden Vergleiche fällt neues Licht auf die spezifische Besonderheit der Ersten Republik und der Situation im Roten Wien. (shrink)

Pekakak selama ini tinggal di gua galiannya sendiri di tepi kolam, tapi sekarang dia memutuskan bahwa dia membutuhkan rumah baru. Dia melakukan tur keliling desa untuk melihat bagaimana burung-burung lain membangun rumah mereka. Dia mengunjungi Tuan Pipit, yang tinggal di pohon pinus yang bersiul. Bagian depan bangunannya tampak indah, dan lokasinya yang tinggi memberikan ventilasi yang baik. Tapi, semakin lama dia menginap, dia jadi semakin pusing. Hembusan angin apa pun yang menerpa membuat seluruh struktur bangunan bergetar seolah-olah akan hancur berantakan.

We can say that we understand neural networks then and only then if you will come to me and say that the best model ever for some task has a 100 layers, and I will answer "No! 101 layers model is the best!".
