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)

Nada hay más confortable para el hombre, ni más peligroso, que las certezas. Nuestra mejor defensa es la filosofía, que consiste engran medida en el arte de cuestionarlas, de atreverse a pensar, de interpelar las verdades establecidas y ver qué esconden. En estepaseo por la historia de la filosofía, Fernando Savater nos presenta a los grandes personajes que con sus preguntas, y en ocasiones con sus respuestas, han marcado el pensamiento occidental. Platón, Aristóteles, Hobbes, Tomás de Aquino, Nietzsche, Marx, (...) Ortega, Wittgenstein y hasta dieciocho filósofos más desfilan por estas páginas de la mano de Savater, que con su habitual estilo lúcido, ameno e inteligente explica sus ideas más importantes y resume sus trayectorias. Un canto al irrenunciable ejercicio de la libertad intelectual, este libro es en realidad una invitación a huir de los tópicos y a compartir con los grandes filósofos la maravillosa aventura de pensar.

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)

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.

Many researchers have assumed that punishment evolved as a behavior-modification strategy, i.e. that it evolved because of the benefits resulting from the punishees modifying their behavior. In this article, however, we describe two alternative mechanisms for the evolution of punishment: punishment as a loss-cutting strategy (punishers avoid further exploitation by punishees) and punishment as a cost-imposing strategy (punishers impair the violator’s capacity to harm the punisher or its genetic relatives). Through reviewing many examples of punishment in a wide range of (...) taxa, we show that punishment is common among plant and animal species and that the two mechanisms we describe have often been important for the evolution of punishment.

En la formación inicial docente, el estudio de la epistemología constituye una pieza fundamental para que los futuros profesores puedan filosofar sobre la realidad de los diversos contextos educativos y se pregunten cómo mejorarla desde los principios que rigen la investigación científica. De este modo, gracias al sustento epistemológico, los estudiantes de pedagogía pueden formarse como docentes investigadores capaces de analizar los cambios sociales propuestos por las múltiples realidades y conocer cómo se construye el conocimiento científico de una especialidad dada. (...) La finalidad de este trabajo, es presentar una reflexión filosófica-epistemológica sobre la imperiosa necesidad de desarrollar el conocimiento epistemológico en la formación inicial del profesorado de matemática e historia, considerando los fundamentos disciplinares, pedagógicos y cognitivos de dichas áreas.

Nesse artigo, eu procuro mostrar que a leitura tradicional que atribui um procedimento dialético à abordagem aristotélica da acrasia, em Ética Nicomaquéia VII 1-3 provoca um sério problema interpretativo ao tentar compatibilizar a posição socrática acerca da acrasia e os phanomena. Primeiramente, tento mostrar, baseando-me numa análise de Tópicos I 1-2, que o procedimento metodológico, em EN VII 1 1145b2-7, não se caracteriza como dialético. Em segundo lugar, proponho uma leitura em que Aristóteles, passo a passo refuta a tese socrática (...) que nega a existência da acrasia, uma vez que esse tese não é contada entre os phainomena que se quer preservar.

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).

Monetary intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the dark side of monetary Intelligence and behavioral economics—dishonesty. Dishonesty, a risky prospect, involves cost–benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: The magnitude and intensity of (...) the relationship between love of money and dishonest prospect may reveal how individuals frame dishonesty in the context of two levels of subjective norm—perceived corporate ethical values at the micro-level and Corruption Perceptions Index at the macro-level, collected from multiple sources. Based on 6382 managers in 31 geopolitical entities across six continents, our cross-level three-way interaction effect illustrates: As expected, managers in good barrels, mixed barrels, and bad barrels display low, medium, and high magnitude of dishonesty, respectively. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities —the Enron Effect, but the lowest in low CPI entities. CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norm, revealing critical implications to the field of behavioral economics and business ethics. (shrink)

The present research used archaeological data, i.e., the data obtained from kamekan jar burials in the Mikuni Hills of the northern Kyushu area in the Mid- dle Yayoi period, to test the parochial altruism model. This model argued that out-group hate and in-group favor coevolved via prehistoric intergroup conflicts. If this model is accurate, such an out-group hate and in-group favor could be re- flected in the archaeological remains, such as pottery making; the more frequent intergroup conflicts are and the (...) more each group is opposed, the more independent and coherent each group will be and more evident cultural identity could be estab- lished within each group. We employed an elliptic Fourier analysis for the shapes of kamekan jar burials. We examined whether frequent intergroup conflicts in the period influenced kamekan jar pottery between subareas of the Mikuni Hills. The results suggested that the shapes of kamekan jar burials after the KIIIa type are slightly different between subareas, which is partially consistent with the model. However, the results do not support the model directly. (shrink)

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)
