This paper analyzes Maurizio Ferraris’s “minimal realism” with the aim of showing that his criticisms of correlationism and constructivism are not convincing. Ferraris preserves both a substantivist vision of the objects of knowledge and a substantial difference between sensible things and concepts. These two issues prevent his Manifesto of New Realism from being considered the founding moment of the “new realism.” The paper concludes with a reflection on those aspects that should be considered and avoided when proposing a philosophical realism.

The free-energy principle (FEP) builds on an assumption that sensor–motor loops exhibit Markov blankets in stationary state. We argue that there is rarely reason to assume a system's internal and external states are conditionally independent given the sensorimotor states, and often reason to assume otherwise. However, under mild assumptions internal and external states are conditionally independent given the sensorimotor history.

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

Caracterización de un grupo de comités de ética en investigación en Colombia Caracterização de um grupo de comitês de ética em pesquisa na Colômbia In the last decades, controlled clinical trials sponsored by the pharmaceutical industry have increased considerably. This has led to the need for greater control and assistance by regulators and ethics committees to ensure appropriate compliance with established ethical standards and good clinical practices in general. In Colombia, the National Food and Drug Surveillance Institute, the regulator in (...) the country, controls and monitors the operation of clinical research with drugs. In 2008, this entity issued Resolution 2378, which provides and regulates research actors in Colombia, including ethics committees. After being in force for several years, it is necessary to know whether research ethics committees in Colombia operate in accordance with this regulation and to determine the status of implementation of the requirements therein. For this purpose, a survey was designed to be voluntarily answered and a response was obtained from 25 of the 69 certified committees in Colombia. Twenty-two of them could be analyzed because their information was complete. Compared with previous studies, favorable changes in development and organization were observed in accordance with the current proposed regulation.

In Brazil, induced abortion in adolescents has been frequent in less-advantaged socioeconomic classes, and the vulnerability of these adolescents has not been addressed. Given this context, the present study sought to investigate the relationship between the practice of abortion and vulnerability in adolescents. This was a descriptive cross-sectional study of 201 adolescents who completed a structured questionnaire that allowed the analysis of variables with respect to intent to abort. The profile of the pregnant adolescents in the sample studied was the (...) following: average age, 16.1 years; stable partner; mulatas; did not use condoms during sexual relations; precocious with respect to their first sexual relations; and did not plan the pregnancy. According to the classification of the World Health Organization, 81.59% of the subjects‘ abortions were known to be induced. Twenty-one were vulnerable to induced abortion; of these, 13 reported forced sexual intercourse, of whom 8 reported that they had suffered associated violence. These results indicate that sexual violence and unwanted pregnancy subject adolescents to a context of greater vulnerability to induced abortion. Thus, it is suggested that this relationship should be considered from the perspective of bioethics and human rights, but always respecting the cultural values of the society in which the adolescents live, as well as their human dignity.

Extensa exposición de la recepción del darwinismo en el Uruguay, que llega hasta la actualidad. Salvo en épocas más recientes, las reacciones, en favor o en contra, fueron de índole ideológica más que científica, especialmente a partir del concocimiento de The descent of man. Las polémicas entre católicos y 'evolucionistas' tienen, según el autor, su punto candente entre 1871-90. Le siguió un período de mayor apaciguamiento, en que la cuestión se consideró en función de los desarrollos de la ciencia biológica. (...) Es obligado poner esta contribución en relación con la obra de Thomas Glick, Darwin y el darwinismo: en el Uruguay y en América Latina (ver HLAS 56:5067)"--Handbook of Latin American Studies, v. 58.

ABSTRACTIn two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes (...) can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality. (shrink)

Antecedente. Se considera «eutanasia» al acto de acabar con la vida del paciente a petición expresa de él, para terminar el sufrimiento propio de alguna enfermedad sin perspectiva de cura. Objetivo. Evaluar los conocimientos y la percepción sobre la eutanasia en estudiantes y profesionales de medicina, demostrando los conocimientos y clasificando la percepción sobre la eutanasia. Metodología. Estudio clínico-epidemiológico, observacional, cualitativo-cuantitativo, de corte transversal y con muestreo no probabilístico por conveniencia, en los estudiantes y profesionales de medicina de un hospital (...) en Venezuela. Resultados. La muestra estudiada tuvo una distribución según grado de instrucción: 64.85% de estudiantes, 19.33% de residentes y 15.82% de especialistas. Presentaron un grado de conocimiento medio, distribuido en 84.4% de especialistas, 77.3% de residentes y 80.5% de estudiantes (p 0.051). De acuerdo con los grados de conocimiento y el apoyo a la eutanasia, el 76.18% tiene un grado medio de conocimientos (p 0.0002). Conclusión. Se demostró que existe un grado medio de conocimiento, en particular en la población estudiantil. La eutanasia no fue percibida de manera negativa, demostrando una alta significancia en la atención a las implicaciones éticas que rodean este concepto. (shrink)

Habituation is defined as a decline in responding to a repeated stimulus. After more than eighty years of research, there is an enduring consensus among researchers on the existence of 9-10 behavioral regularities or parameters of habituation. There is no similar agreement, however, on the best approach to explain these facts. In this paper, we demonstrate that the Sometimes Opponent Processes (SOP) model of stimulus processing accurately describes all of these regularities. This model was proposed by Allan Wagner as a (...) quantitative elaboration of Priming Theory, which states that the processing of a stimulus, and therefore its capacity to provoke its response, depends inversely on the degree to which the stimulus is pre-represented in short-term memory. Using computer simulations, we show that all the facts involving within-session effects or short-term habituation might be the result of priming from recent presentations of the stimulus (self-generated priming). The characteristics involving between-sessions effects or long-term habituation would result from the retrieval of the representation of the stimulus from memory by the associated context (associatively-generated priming).

This paper presents ongoing research towards understanding the discourse and workspace in computer-mediated interactions. We present a series of methods developed to study non-collocated computer-mediated interactions. These methods were developed originally to study interactions involving teams composed of architecture, engineering, and construction management students as part of the AEC Global Teamwork course offered at Stanford University in collaboration with universities worldwide since 1993. The methods stress the value of using ethnographic approaches, particularly the role that both discourse and workspace have (...) in developing the communication processes involved in the interactions. We used the AEC Global Teamwork course as a testbed and focused on issues regarding the nature of the communication act in building design projects when mediated by computers. We successfully tested these new methods and present the preliminary results. (shrink)

The current global-justice literature starts from the premise that world poverty is the result of structural injustice mostly attributable to past and present actions of governments and citizens of rich countries. As a result, that literature recommends vast coercive transfers of wealth from rich to poor societies, alongside stronger national and international governance. Justice at a Distance, in contrast, argues that global injustice is largely home-grown and that these native restrictions to freedom lie at the root of poverty and stagnation. (...) The book is the first philosophical work to emphasize free markets in goods, services, and labor as an ethical imperative that allows people to pursue their projects and as the one institutional arrangement capable of alleviating poverty. Supported by a robust economic literature, Justice at a Distance applies the principle of noninterference to the issues of wealth and poverty, immigration, trade, the status of nation-states, war, and aid.

Na medida em que o termo espiritualidade é em si mesmo ambíguo, o desafio específico da pesquisa em espiritualidade e saúde enquanto campo é definir de que maneiras o conceito ‘espiritualidade’ pode ser frutiferamente aplicado à saúde física e mental. Uma vez que a relatividade hermenêutica de um conceito humanístico tem de se relacionar com os resultados mensuráveis das ciências empíricas, algumas dificuldades inevitavelmente surgem. Isso não impediu, contudo, a formação de duas abordagens claramente definidas na pesquisa em espiritualidade e (...) saúde; uma a que poderíamos chamar hermenêutica-existencial e a outa mais relacionada às ciências da natureza. Por falharmos em distinguir essas opções, muitas das interações entre a ciência da religião ou os estudos da religião e a pesquisa em espiritualidade e saúde é prejudicada ao ponto da quase ausência de diálogo. Nosso intuito aqui é apresentar e conceituar as duas alternativas nos termos das ciências humanas. (shrink)

A abordagem deste artigo trata de uma busca pelo sentido ontológico da vida humana em relação ao seu modo de ser e estar no mundo e com o mundo. Partindo de uma breve contextualização sobre a vastidão do cosmos, mostramos, direta e indiretamente, o paradoxal legado da ciência moderna que, de um lado, hoje evidencia nossa insignificância diante da infinitude do universo e, de outro, promoveu antinomias sociais por sua incansável busca pela dominação da natureza. O resultado desse processo é (...) um antropocentrismo desastroso em relação às questões ambientais. O ensaio, eminentemente teórico, promove um diálogo, a múltiplas vozes, na tentativa de angariar fundamentos éticos e epistemológicos para a Educação Ambiental. Trata-se de um estudo de metodologia bibliográfica. Destarte, em nossa abordagem, a filosofia figura com seu papel de buscar permanentemente pelo sentido e significado da vida, dos fenômenos humanos e não humanos. Defenderemos a tese de que é necessário e emergente o reconhecimento da esfera noológica da humanidade, pois se continuarmos a negligenciá-la incorreremos no risco de mantermos sufocado o lado demens do ser humano. Amparados pelas contribuições do pensador francês Edgar Morin, buscamos fundamentos filosóficos para a Educação Ambiental por querermos afirmá-la como campo de saberes e conhecimentos que promovem a busca pelo sentido da vida e a compreensão sobre a condição humana nacontemporaneidade. A ciência moderna promoveu a matematização e o desencantamento do mundo, fazendo com que o epíteto sapiens de nossa nomenclatura taxonômica ganhasse a companhia do epíteto degradandis. Para que seja possível a revitalização dos sentidos sobre a existência humana, é necessário que o epíteto sapiens seja acompanhado, metaforicamente, da desinência demens.

El presente artículo tiene como objetivo contribuir en la discusión sobre el incremento del complejo y multifacético fenómeno de recampesinización que acontece en la actual etapa de desarrollo capitalista, analizando uno de sus aspectos menos conocidos que está relacionado al movimiento denominado como “contraculturas espaciales”. Las contraculturas espaciales son experimentos de organización socio-espacial de carácter “alternativo” que se popularizaron principalmente en la década de 1960. A partir de los años 1990, acompañando un nuevo periodo de crisis del capitalismo, se evidencia (...) la renovación y el fortalecimiento de dicho movimiento, con el surgimiento de nuevas experiencias de este tipo, muchas de las cuales están inspiradas por la permacultura, concepto que se refiere al diseño de asentamientos humanos sustentables. Basándose en dos casos, uno en Argentina y otra en Cuba, se discutirá de qué maneras la permacultura puede estar promoviendo, en la actualidad, el surgimiento de “nuevos campesinos”. (shrink)

Este artigo apresenta o projeto de G. Vico para o estabelecimento da ciência moral. Vico esteve empenhado na emancipação do estudo das manifestações objetivas do espírito por intermédio da reforma do racionalismo cartesiano. A crítica ao iluminismo é feita com a retomada do conceito de barbárie no âmbito da filosofia, contrapondo-o ao conceito de esclarecimento do Século das Luzes.
