Administraation of antiretroviral therapy to women during pregnancy, labor and delivery, and to infants postnatally can dramatidy reduce mother-to- child HIV transmission. However, pregnant women need to know that they are HIV-infected to take advantage of antiretroviral therapy, and many women do not know their HIV status. One-half of HIV-infected infants in the United States were bornto women who had not been tested for HIV or for whom the time of testing was not known. Although fewer than 400infants are infected (...) perinatally in the United States each year, that number could be reduced even further through policies aimed at HIV testing during pregnancy.The reasons toadopt such a policy are strong: the pathophysiology of perinatal transmission is clear, prophylaxis is effective and safe, and the intended beneficiaries of the intervention - babies - cannot protect themselves.

This study explores linkages between what Chinese managers generally know about environmental issues, how strongly they value environmental protection, and different types of behaviours/actions they may take within their organizations on behalf of the environment. From a sample of 305 managers in Guangzhou and Beijing, it was found that both environmental knowledge and values are more predictive of more personal managerial behaviours, such as keeping informed of relevant company issues and working within the system to minimize environmental impacts, than more (...) overt behaviours. Moreover, for these more personal actions, environmental knowledge and values were found to have both main and interactive effects. By comparison, it was found that both environmental values and knowledge had additive effects on managerial tendencies to initiate new programs within their domain of responsibility. Only environmental values was found to have a modest influence environmental advocacy. (shrink)

What do we do when we say ‘We’? This paper pursues a response from analytic pragmatism. The guiding idea of analytic pragmatism is to look to what one must implicitly know how do to be able to use expressions to say something, including how to make that implicit know-how explicit. Accordingly, the question we are tasked to answer is what one must know how to do to say ‘We’ – that is, what practical know-how saying ‘We’ requires and can be (...) employed to make explicit. The concept normative ascent is introduced in developing an answer. On this approach, the know-how in question turns out to be a distinctively normative capacity. Both being and saying ‘We’ turns out to involve being able to do and say something normative. (shrink)

Research has underlined that moral disengagement processes, by which people switch off their moral values and act aggressively without experiencing guilt, are highly connected with contextual factors. However, research on situational variations in moral disengagement is limited, especially considering the associations with characteristics such as the ethnic origin of potential victims. The general aim of the present study was to develop a brief, specific measure of ethnic moral disengagement able to catch individual justification used in the case of ethnic bullying (...) and cyberbullying, and test its validity and reliability. An eight items scale was developed and administered in study 1, in a sample of 961students attending several Italian high schools. Considering the results of the CFA, we modified one of the items and the scale was administered again, in a second sample of 1,229 students in study 2. A one-factor model of ethnic moral disengagement fit the data well and internal consistency showed to be good. As an additional step, we found that the model was invariant across Italian adolescents and youths with a different ethnic or culture of origin strengthened our confidence regarding the factorial integrity of the scale. Last, the scale showed to be positively associated with ethnic bullying and cyberbullying. Generally, findings suggested that the Ethnic Moral Disengagement scale can be a useful tool for those interested in measuring moral disengagement and evaluating how it impacts bullying and cyberbullying of minority groups.

Perspectivas: una aproximación al pensamiento ético y político contemporáneo recoge algunas de las conferencias pronunciadas en unas jornadas sobre pensamiento crítico, tituladas ¿Liquidar la Modernidad?, que tuvieron lugar en la Biblioteca María Moliner de la Facultad de Filosofía y Letras de la Universidad de Zaragoza en 2010. Y por otro lado, recopila las cuatro intervenciones que se produjeron en una jornada sobre pensamiento contemporáneo que, dirigida a profesorado de enseñanza secundaria, tuvo lugar en el Paraninfo de la Universidad de Zaragoza (...) el 26 de noviembre de 2011. El libro pretende también contribuir a establecer vínculos estrechos entre el Departamento de Filosofía y el profesorado de secundaria con el fin, entre otras cuestiones, de implicarse en la mejor preparación del alumnado de cara a la Prueba de Acceso a la Universidad y de facilitar la tarea docente del profesorado. En ese sentido, y puesto que actualizar el programa, dando cabida al siglo XX, parecía una cuestión necesaria, se ha configurado una aproximación a algunos autores y autoras contemporáneos, en la dimensión ética y/o política de su pensamiento, que también puede resultar útil para el profesorado de Filosofía en enseñanza secundaria.

When applied in the health sector, AI-based applications raise not only ethical but legal and safety concerns, where algorithms trained on data from majority populations can generate less accurate or reliable results for minorities and other disadvantaged groups.

En el marco de los treinta años de la publicación en castellano de la segunda edición de la Teoría pura del derecho y de los setenta y cinco años de la primera publicación en alemán de dicha obra, del profesor austriaco Hans Kelsen, el Programa de Derecho de la Facultad de Relaciones Internacionales y Ciencias Jurídicas y Políticas de la Universidad de Bogotá Jorge Tadeo Lozano, celebró, en octubre de 2009, el Congreso Académico Internacional Hans Kelsen: una Teoría Pura del (...) Derecho, del cual se originó el libro que lleva el mismo nombre. La relevancia que produjo dicho evento en el ámbito académico, así como el interés despertado para la generación de un espacio similar con otros autores de importancia para la ciencia jurídica, se establecieron como el punto de encuentro y la razón de producción de aquello que lleva el nombre hoy de jornadas Académicas Internacionales de Argumentación y Filosofía del Derecho que, adicionalmente, sirvieron para una modulación de actividades desarrollas en el Foro de Interpretación, Argumentación y Decisión judicial del año 2010, llevado a cabo en nuestra Universidad, con presencia del profesor portugués Boaventura de Sousa Santos.

O movimento em direção à escola inclusiva é um dos grandes desafios do cenário educacional. Como transitar da cultura da homogeneidade para a diversidade e avançar no processo de mudança dessa cultura é o tema deste artigo. A ideia de uma comunidade de aprendizes é o princípio que instala a ruptura de concepções cristalizadas de uniformidade e remete a um novo olhar inclusivo. Aborda o universo da inclusão e contempla a ressignificação das variáveis do projeto pedagógico presente no contexto da (...) escola, da família e dos profissionais da rede de apoio. Faz um convite à reflexão e propõe aos defensores da mudança uma nova cultura, um novo jeito de ser e de fazer a escola inclusiva. (shrink)

We analyze contestants’ behavior in the game show “The Weakest Link”. We focus on banking decisions, where a contestant chooses to secure an amount of money for the eventual winner, or to risk it on a general knowledge question. We find that contestants do not use the banking strategy that maximizes total expected prize money. Average earnings could be at least 17% higher. Our results suggest that contestants are not overconfident, but do try to convince other contestants that their ability (...) is higher than it really is, in order to increase chances of winning the prize. We argue that this mechanism may also be applicable to other situations that are of economic interest. (shrink)

Recently, we reported that melanoma risk in redheads is linked not only to pale skin, but also to the synthesis of the pigment – called pheomelanin – that gives red hair its color. We demonstrated that pheomelanin synthesis is associated with increased oxidative stress in the skin, yet we have not uncovered the chemical pathway between the molecule pheomelanin and the DNA damage that drives melanoma formation. Here, we hypothesize two possible pathways. On one hand, pheomelanin might generate reactive oxygen (...) species (ROS) that directly or indirectly cause oxidative DNA damage. On the other hand, pheomelanin synthesis might consume cellular antioxidant stores and make the cell nucleus more vulnerable to other endogenous ROS. Uncovering the mechanistic pathway between pheomelanin and oxidative DNA damage will be an important step in developing strategies to lower melanoma risk in redheads. (shrink)

Senza una filosofia della storia, la storia non è altro che un incomprensibile susseguirsi di eventi che non trasmette le autentiche motivazioni umane ad agire. Capire il fine ultimo della storia significa porsi in un'ottica assoluta, metafisica, abbandonando la concezione del corpo sociale come semplice lotta per la sopravvivenza. In questo senso la filosofia è sorella della teologia come dimostrano, secondo Karl Lowith, le tappe fondamentali del pensiero europeo. Dalla Bibbia a sant'Agostino, da Voltaire a Marx, da Vico a Hegel, (...) l'interpretazione filosofica della storia rimane ancorata a un'originaria matrice religiosa. Anche quando alla fede e all'idea di provvidenza sostituisce quella di progresso. (shrink)

El interés de la presente compilación es el de recoger algunas de las principales reflexiones del pensamiento político contemporáneo. Se propone como tarea central el examen y la problematización de algunos presupuestos extendidos en la tradición de la filosofía occidental. Por medio de este cuestionamiento, se busca desestabilizar asunciones que atraviesan nuestros modos habituales de concebir el sujeto, la acción y el espacio políticos, y de comprender la manera como estos son configurados por el lenguaje. Es así como una amplia (...) gama de autores encuentra un espacio común de discusión: la urgencia de plantear alternativas tanto crítica como de compresión de lo político, que permitan movilizar nuevas maneras de concebir la acción y la configuración de nuestros modos de ser en común; alternativas que incluso pueden encontrarse ya allí, a la sombra de lo político, en sus recodos escondidos, silenciados; en lugares o motivos que tal vez han pasado desapercibidos por no hacer parte de un discurso e interpretación dominantes. En particular, interesa aquí rescatar aquellas reflexiones que abordan esta tarea desde tres ejes temáticos concretos: la pregunta por la relación entre ley y violencia, la necesidad de repensar el ser en común, y, por último, el problema de cómo concebir los pasajes y discontinuidades entre la singularidad de la contingencia histórica, cultural, lingüística, y la posibilidad o promesa de lo universal.

Sumner B. (Barney) Twiss, who died in 2023, was for ten years a General Editor of the Journal of Religious Ethics (JRE). He was a frequent contributor of articles, a member of the JRE Editorial Board, and a member of the journal's Board of Trustees. In this article, colleagues and students reflect on some of his many contributions, not only to the JRE but to the broader discursive fields of comparative religious ethics and human rights.
