O contributo da educação filosófica na construção de uma cultura democrática

O presente relatório está organizado em duas componentes fundamentais. A primeira, caracterizada pela sua dimensão descritiva, procura relatar com rigor os momentos mais significativos da experiência lectiva como professor estagiário na Escola Secundária de Miraflores ao longo do ano escolar de 2013/2014. Na segunda parte deste documento, de índole mais reflexiva do que descritiva, explorar-se-á o contributo da educação filosófica para o cumprimento de um novo imperativo educativo que o ‘aprender a viver juntos’ exige. Nesse sentido, procurar-se-á demonstrar de que modo o ensino da Filosofia no ensino secundário pode ser vinculativo de princípios fundamentais de cidadania e, como tal, potenciar a construção de uma sociedade assente em competências e valores democráticos.

How effective is dog culling in controlling zoonotic visceral leishmaniasis? a critical evaluation of the science, politics and ethics behind this public health policy

INTRODUCTION: Zoonotic kala-azar, a lethal disease caused by protozoa of the genus Leishmania is considered out of control in parts of the world, particularly in Brazil, where transmission has spread to cities throughout most of the territory and mortality presents an increasing trend. Although a highly debatable measure, the Brazilian government regularly culls seropositive dogs to control the disease. Since control is failing, critical analysis concerning the actions focused on the canine reservoir was conducted. METHODS: In a review of the literature, a historical perspective focusing mainly on comparisons between the successful Chinese and Soviet strategies and the Brazilian approach is presented. In addition, analyses of the principal studies regarding the role of dogs as risk factors to humans and of the main intervention studies regarding the efficacy of the dog killing strategy were undertaken. Brazilian political reaction to a recently published systematic review that concluded that the dog culling program lacked efficiency and its effect on public policy were also reviewed. RESULTS: No firm evidence of the risk conferred by the presence of dogs to humans was verified; on the contrary, a lack of scientific support for the policy of killing dogs was confirmed. A bias for distorting scientific data towards maintaining the policy of culling animals was observed. CONCLUSIONS: Since there is no evidence that dog culling diminishes visceral leishmaniasis transmission, it should be abandoned as a control measure. Ethical considerations have been raised regarding distorting scientific results and the killing of animals despite minimal or absent scientific evidence

Machine ethics via logic programming

Machine ethics is an interdisciplinary field of inquiry that emerges from the need of imbuing autonomous agents with the capacity of moral decision-making. While some approaches provide implementations in Logic Programming (LP) systems, they have not exploited LP-based reasoning features that appear essential for moral reasoning. This PhD thesis aims at investigating further the appropriateness of LP, notably a combination of LP-based reasoning features, including techniques available in LP systems, to machine ethics. Moral facets, as studied in moral philosophy and psychology, that are amenable to computational modeling are identified, and mapped to appropriate LP concepts for representing and reasoning about them. The main contributions of the thesis are twofold. First, novel approaches are proposed for employing tabling in contextual abduction and updating – individually and combined – plus a LP approach of counterfactual reasoning; the latter being implemented on top of the aforementioned combined abduction and updating technique with tabling. They are all important to model various issues of the aforementioned moral facets. Second, a variety of LP-based reasoning features are applied to model the identified moral facets, through moral examples taken off-the-shelf from the morality literature. These applications include: (1) Modeling moral permissibility according to the Doctrines of Double Effect (DDE) and Triple Effect (DTE), demonstrating deontological and utilitarian judgments via integrity constraints (in abduction) and preferences over abductive scenarios; (2) Modeling moral reasoning under uncertainty of actions, via abduction and probabilistic LP; (3) Modeling moral updating (that allows other – possibly overriding – moral rules to be adopted by an agent, on top of those it currently follows) via the integration of tabling in contextual abduction and updating; and (4) Modeling moral permissibility and its justification via counterfactuals, where counterfactuals are used for formulating DDE.

Appreciating the power of words and imaginative organizing: A triadic model of ethics practiced in everyday conversations

This thesis provides an alternative framework to analyze power and ethics practiced in everyday conversations, which constitute processes of organizing. Drawing upon narrative frameworks, the analyses of messages posted on an online message board demonstrate people’s imaginative capacity to create relevant stories, in respect of their precise grasp of factual understandings, contextual relevance and evaluative/moral appropriateness, by appropriating others’ words. Based on the empirical analyses, the thesis indicates that studies on power and ethics in organizations can be re-oriented towards appreciating irremediable power imbalances by offering alternative ways of member’s denoting experiences of power.

Ciudadanía y bien común en el marco de una ética pública. Citizenship and common good in the frame of a public ethics.

La investigación pretende hacer aportes para la reformulación ético-discursiva de las ideas de ciudadanía y bien común, que sea capaz de articular la libertad y la equidad con la corresponsabilidad solidaria en contextos post-neoliberales de globalización, interculturalidad y exclusión. En este sentido, una reconfiguración de la sociedad y de la ciudadanía implicará mostrar en qué sentido y de qué modo el espacio público tiene que estar abierto no sólo a la competencia y a los consumidores, sino a ciudadanos ilustrados, autónomos y críticos. La investigación parte del supuesto que, desde los presupuestos teóricos, conceptuales y metodológicos de la teoría del discurso y de la teoría de la democracia deliberativa es posible reformular un concepto de bien común apto para articular la integración social en contextos de interacción pluralista y conflictiva, como son las democracias actuales. Puede parecer extraño, y no sin razón, que el concepto de bien común pueda ser rehabilitado en el contexto de sociedades pluralistas y democráticas, e incorporada convincentemente en la estructura de una nueva ética cívica. La extrañeza puede ser aún mayor si se piensa que, en la actualidad, la formulación de una nueva ética cívica se ve enfrentada tanto a desafíos internos, estrictamente ético-filosóficos, como externos, provenientes de problemas y conflictos histórico-contextuales y culturales (Michelini, 1998, 2000). Finalmente, es posible que la supuesta extrañeza esté relacionada también con el hecho de que el concepto de bien común sea empleado no sólo de modo ambiguo, sino que, además, haya sido utilizado en prácticas muy diversas: desde la búsqueda filosófica de la ciudad perfecta y del Estado ideal -en la que Platón manifiesta que "las cosas de los amigos deben ser comunes" (Platón, 1974a, V, 424a, 449c; 1974b, 739a-e)-, hasta las múltiples instrumentalizaciones históricas en las que el concepto de bien común se utilizó para articular la religión con el patriotismo o la razón de Estado. En la historia más o menos reciente de muchos países latinoamericanos encontramos, en este respecto, ejemplos trágicos: en nombre de la razón de Estado y del bien común, no pocas veces se ha pretendido mantener el orden establecido o defender una determinada ideología, incluso vulnerando la legitimidad del Estado de Derecho y lesionando normas éticas fundamentales. El objetivo general de la investigación es fundamentar un sustento teórico coherente para una reelaboración de los conceptos de ciudadanía y bien común en vista de una ética pública de la corresponsabilidad solidaria en sociedades democráticas y en contextos de globalización, interculturalidad y exclusión, e indagar acerca de su aplicabilidad a los campos de la práctica política y educativa. Los resultados del proyecto tendrán un impacto no sólo teórico, sino también práctico en el ámbito de las ciencias humanas, particularmente en el ámbito de la filosofía práctica, la ética pública, la política y el sistema educativo. Además, se propone elaborar lineamientos de acción para las instituciones sociales, educativas y políticas locales, regionales y nacionales, ayudar a esclarecer aspectos centrales de una convivencia democrática y pluralista, y contribuir al esclarecimiento de los deberes, de los derechos y de la corresponsabilidad solidaria.
