This article gives a conceptual review of the e-value, ev(H|X) – the epistemic value of hypothesis H given observations X. This statistical significance measure was developed in order to allow logically coherent and consistent tests of hypotheses, including sharp or precise hypotheses, via the Full Bayesian Significance Test (FBST). Arguments of analysis allow a full characterization of this statistical test by its logical or compositional properties, showing a mutual complementarity between results of mathematical statistics and the logical desiderata lying at (...) the foundations of this theory.

The unit root problem plays a central role in empirical applications in the time series econometric literature. However, significance tests developed under the frequentist tradition present various conceptual problems that jeopardize the power of these tests, especially for small samples. Bayesian alternatives, although having interesting interpretations and being precisely defined, experience problems due to the fact that that the hypothesis of interest in this case is sharp or precise. The Bayesian significance test used in this article, for the unit root (...) hypothesis, is based solely on the posterior density function, without the need of imposing positive probabilities to sets of zero Lebesgue measure. Furthermore, it is conducted under strict observance of the likelihood principle. It was designed mainly for testing sharp null hypotheses and it is called FBST for Full Bayesian Significance Test.

To estimate causal relationships, time series econometricians must be aware of spurious correlation, a problem first mentioned by Yule (1926). To deal with this problem, one can work either with differenced series or multivariate models: VAR (VEC or VECM) models. These models usually include at least one cointegration relation. Although the Bayesian literature on VAR/VEC is quite advanced, Bauwens et al. (1999) highlighted that “the topic of selecting the cointegrating rank has not yet given very useful and convincing results”. The (...) present article applies the Full Bayesian Significance Test (FBST), especially designed to deal with sharp hypotheses, to cointegration rank selection tests in VECM time series models. It shows the FBST implementation using both simulated and available (in the literature) data sets. As illustration, standard non informative priors are used. (shrink)

ABSTRACTThis paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non‐viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral (...) status of the fetus, the cornerstone thesis of the Catholic Church.

ABSTRACT The presence of truth and honesty is a permanent demand, and becomes vital the more committed and intimate a relationship is. Medical practice is relevant to this discussion when one questions whether or not a physician should always tell their patient the truth in the face of a progressive or potentially fatal disease, regarding the diagnosis, outcome, therapy and evolution of the specific disease. From this discussion we aim, with the present report, to look at the truth applicable to (...) the patient‐physician relationship, and its ethical and moral implications; and also to look at where the Brazilian Code of Medical Ethics (BCME) and the medical literature stand regarding this issue. One concludes that there are only two moments not to tell a patient the truth: when the patient does not want to be informed, and when the truth could be iatrogenic. The question now is, when would the truth be iatrogenic? Physicians, in our opinion, would not be able to judge solitarily when the truth might be deleterious to their patient. Alternatively, we propose the appointment of a multidisciplinary commission to help the doctor with such a decision. (shrink)

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, (...) a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

Inicialmente, o texto indaga sobre o significado do exercício do filósofo social; pretende também localizar as origens do debate moderno sobre ‘subjetividade’ no pensamento filosófico e social. As idéias norteadoras de Kant, se situam na confluência e na disjunção entre razão (conhecimento) e subjetividade (moral). A partir dessa referência, o debate entre alguns pensadores considerados como pós-modernos (Badiou e Zizek), por um lado, e por outro Castoriadis que recusa esta nomenclatura, vão derivando idéias novas sobre ‘sujeito’ e ‘verdade’. Esse debate (...) não é sem conseqüências para a teoria sociológica que assume para si o desafio de introduzir a categoria de ‘sujeito’ em seus cânones (Touraine). As reflexões de Stengers servem também para questionar e aproximar as práticas da produção do conhecimento e dos discursos científicos. Finalmente, restam desafios para se pensar teorias e práticas sócio-ambientais à luz desses conceitos apresentados ao longo do texto. (shrink)

The Cuban government has undertaken the task of transforming insect pest and weed management from conventional to organic and more sustainable approaches on a nationwide basis. This paper addresses past programs and current major areas of research and implementation as well as provides examples of programs in insect and weed management. Topics covered include the newly constructed network of Centers for the Reproduction of Entomophages and Entomopathogens (CREEs), which provide the infrastructure for the implementation of biological control on state, cooperative, (...) and private farm operations. CREE programs include the mass rearing and release of Trichogramma spp. to manage insect pests of cassava, tobacco, sugarcane, and improved pasture. The entomopathogens, Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, are being mass produced in the CREEs and applied to control a number of key insect pests. A traditional method employed by peasant farmers of using the predatory ant Pheidole megacephala (Fabricius) in the biological control of sweetpotato and banana insect pests has been further developed and implemented. Efforts are underway to rear nematode species that attack insect pests and identify plant extracts with insecticidal qualities as potential management tools. Weed management has moved away from dependence on herbicides and toward alternative techniques that include weed suppression based on rotation schemes, limited use of selective herbicides, and new tillage equipment and practices.

Embora elaborada principalmente na década de 1970 a ética de Hans Jonas permanece atual e é particularmente relevante pelo uso da metafísica em um contexto pós-moderno (algo inusitado e ousado) e por sua teoria dos valores que podem ser atribuídos ao ser e ao não-ser. Pretende-se aqui apresentar as limitações que Jonas detectou nas éticas tradicionais (judaico-cristã, kantiana, por exemplo) e analisar as soluções por ele propostas (notadamente heurística do medo e futurologia comparada). Compreender também a fundamentação de tais soluções (...) (um dos maiores desafios da ética jonasiana). A pesquisa baseou-se em uma revisão bibliográfica que envolve a fonte primária, a obra de Jonas, e fontes secundárias. Constatou-se que a ética de Jonas surge da detecção de um niilismo tanto prático quanto teórico que permitiu um avanço desenfreado da técnica. É necessário então submeter a atividade humana à ética novamente. Para tanto foi utilizada uma ontologia que atribui relevância ética ao metabolismo (e não à razão). Deste modo, a ética da responsabilidade objetiva combater o niilismo e o ceticismo moral e supervisionar o progresso técnico, garantindo assim a existência de uma vida humana autêntica e de uma natureza que tem a si própria como fim.

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

Interesante y muy bien lograda aproximación al universo teórico construido por Ricardo Guastini, filósofo del derecho italiano.

In this article, I will analyse the conduct of the Brazilian legislative process regarding new reproductive technologies, mainly the moral assumptions of three categories that are essential to the debate: the status of the child generated by these techniques; the number of embryos transferred in each cycle ; and the issue of women’s eligibility for such techniques. The analysis will be a sociological study of the Brazilian legislative debate, using feminist perspectives in ethics as the theoretical reference. The focus will (...) be the bills in progress in the Brazilian National Congress, the public and official declarations of legislators involved in the issue and the regulation of the medical class, which has influenced the legislative process. Aside from the analysis of the legislative process, I include a section on the justification of these bills, since that is where the legislator exposes what he/she believes is the moral support for the bill.

In Brazil, social science research ethics is a field still under construction and subject to intense dispute. The aim of this paper is to discuss how accepted principles of biomedical research ethics can be incorporated into the ethical review of social sciences, particularly open interviews, ethnographic research, and participant observation. The paper uses a case study—the ethnographic documentary Severina’s Story—as the basis for analysis of the methodological and ethical issues raised in social science research. To promote ethical social science research, (...) based on principles such as human rights and the protection of vulnerable populations, institutional review boards must be sensitive to the epistemological and methodological particularities of all fields of human subjects research.

o presente trabalho pretende investigar tópicos da leitura que Georges Bataille faz da obra de Sade. Trata-se de uma leitura na qual se busca conjugar temas de Hegel com a literatura sadeana. Mais especificamente, Bataille busca entender uma dinâmica de reconhecimento, conforme lida por Kojève, no modo como Sade propõe para nós o desejo, a partir de sua literatura erótica marcadamente peculiar. Para tanto, após uma breve introdução, veremos como Bataille entende o processo antropogênico, o que desse pensamento pode ser (...) retraçado à leitura kojèviana de Hegel e, enfim, como Bataille observa esses elementos na obra do Marquês de Sade.

This article discusses some continuous limit cases of Susan Haack’s crossword puzzle metaphor for the coherent development and foundation of science. The main objective of this discussion is to build a bridge between Haack’s foundherentism and the epistemological framework of objective cognitive constructivism, including its key metaphor of objects as tokens for eigen-solutions. The historical development of chemical affinity tables is used to illustrate our arguments.

In this article, we discuss some issues concerning magical thinking—forms of thought and association mechanisms characteristic of early stages of mental development. We also examine good reasons for having an ambivalent attitude concerning the later permanence in life of these archaic forms of association, and the coexistence of such intuitive but informal thinking with logical and rigorous reasoning. At the one hand, magical thinking seems to serve the creative mind, working as a natural vehicle for new ideas and innovative insights, (...) and giving form to heuristic arguments. At the other hand, it is inherently difficult to control, lacking effective mechanisms needed for rigorous manipulation. Our discussion is illustrated with many examples from the Hebrew Bible, and some final examples from modern science. (shrink)

This article has as its theme the democracy as fundamentalism, or the democratic fundamentalism. Its main objective is the recognition that the thinking about democracy can itself be fundamentalist, implying that not only religious fundamentalisms are a threat to contemporary democracy. Its method and object are the interpretation of texts by two contemporary philosophers who do not usually talk to each other, the Italian Gianni Vattimo and the French Jean-Luc Nancy. The essay's thesis is the affirmation of democratic thinking as (...) a form of fundamentalism, insofar as it fulfills certain conditions established by the two thinkers analyzed. These conditions are, in the language of the aforementioned philosophers, the framing of democracy under the so-called strong thought, or its subsumption to a metaphysical way of thought, so that it becomes incapable of self-criticism and its necessary reinvention. Thus, it is expected to contribute to the construction of a self-critical vision of democracy through dialogue with aspects of thought little known of important philosophers and also through the dialogue between philosophy and theology as emancipatory ways of knowing.

This article provides a critical reading of the ‘Parecer CNE-CES 60, de 2014’, from the Ministry of education, Brazil, which defines the curriculum guidelines for courses of Baccalaureate in Theology. In its first section it discusses the theoretical background of the ‘Parecer’, questioning its illuminist orientation, as well as its pedagogical theory focused on contents and not on the students activities. It aims to show that are two opposed educational paradigms in the ‘Parecer’, the illuminist and the constructivist, although the (...) illuminist is the dominant one. It also question the view of the theologian present in the ‘Parecer’, marked by significant absences from the professional field of religious work. In the second section, the article presents a sample of particular interpretation of the ‘Parecer’, indicating the guidelines of a curriculum based on the constructivist paradigm. It dedicates special attention to the occult dimension of the curriculum and to an articulation of the student’s activities in relationship to the disciplines of the course. (shrink)

Neste artigo visa-se demarcar os intercursos da ética do discurso de Habermas e da psicologia genética de Lawrence Kohlberg. Se, por um lado, para o filósofo alemão a sua proposta ética pode contribuir para suprir os déficits da psicologia genética em relação ao desenvolvimento moral, por outro lado, a ética do discurso se apoia nas pesquisas empíricas realizadas pelos teóricos da psicologia e, com isso, reforçam a tese da universalidade ética defendida por Habermas e Carl Otto-Apel. No entanto, há limites (...) na demarcação da filosofia e da psicologia por se tratar de campos nos quais as metodologias não se identificam e por assumirem perspectivas epistemológicas distintas, descritiva para a psicologia do desenvolvimento e prescritiva para a ética do discurso. Ainda assim, a filosofia de Habermas pretende estabelecer uma relação com campos distintos de saberes, a partir dos quais garante a interdisciplinaridade e a abertura para o diálogo constante entre saberes diversos.

Although logical consistency is desirable in scientific research, standard statistical hypothesis tests are typically logically inconsistent. To address this issue, previous work introduced agnostic hypothesis tests and proved that they can be logically consistent while retaining statistical optimality properties. This article characterizes the credal modalities in agnostic hypothesis tests and uses the hexagon of oppositions to explain the logical relations between these modalities. Geometric solids that are composed of hexagons of oppositions illustrate the conditions for these modalities to be logically (...) consistent. Prisms composed of hexagons of oppositions show how the credal modalities obtained from two agnostic tests vary according to their threshold values. Nested hexagons of oppositions summarize logical relations between the credal modalities in these tests and prove new relations. (shrink)

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)

The main goal of this article is to use the epistemological framework of a specific version of Cognitive Constructivism to address Piaget’s central problem of knowledge construction, namely, the re-equilibration of cognitive structures. The distinctive objective character of this constructivist framework is supported by formal inference methods of Bayesian statistics, and is based on Heinz von Foerster’s fundamental metaphor of objects as tokens for eigen-solutions. This epistemological perspective is illustrated using some episodes in the history of chemistry concerning the definition (...) or identification of chemical elements. Some of von Foerster’s epistemological imperatives provide general guidelines of development and argumentation. (shrink)
