“Para que isso servirá em minha vida?” Ao longo de minha trajetória como professor do ensino secundário, ouvi esta pergunta algumas vezes. É provável que nós professores de filosofia não sejamos um alvo privilegiado dessa pergunta provocadora. Trata-se mesmo de uma questão legítima, ainda mais para nós: latinoamericanos, brasileiros, nordestinos, piauienses. Trata-se de uma pergunta que evoca um certo desespero, uma certa pressa, um tipo de agonia que é bem nossa; como quando dizemos “estou agoniado”. Queremos tudo “pra já”. Parece (...) que jamais nos daremos o direito de viver e aprender algo pelo simples fato de que o saber é bom e merece ser fruído. (shrink)

This paper was presented at the First Conference of the ISSEI ‘Turning Points in History’, 26–30 September 1988. It belongs to Theme 1, ‘Comparative History of European Revolutions’.

Social dilemmas occur when the pursuit of self-interest by individuals in a group leads to less than optimal collective outcomes for everyone in the group. A critical assumption in the human sciences is that people's choices in such dilemmas are individualistic, selfish, and rational. Hence, cooperation in the support of group welfare will only occur if there are selfish incentives that convert the social dilemma into a nondilemma. In recent years, inclusive fitness theories have lent weight to such traditional views (...) of rational selfishness on Darwinian grounds. To show that cooperation is based on selfish incentives, however, one must provide evidence that people donotcooperatewithoutsuch incentives. In a series of experimental social dilemmas, subjects were instructed to make single, anonymous choices about whether or not to contribute money for a shared “bonus” that would be provided only if enough other people in the group also contributed their money. Noncontributors cited selfish reasons for their choices; contributors did not. If people are allowed to engage in discussion, they will contribute resources at high rates, frequently on irrational grounds, to promote group welfare. These findings are consistent with previous research on ingroup biasing effects that cannot be explained by “economic man” or “selfish gene” theories. An alternative explanation is that sociality was a primary factor shaping the evolution ofHomo sapiens. The cognitive and affective mechanisms underlying such choices evolved under selection pressures on small groups for developing and maintaining group membership and for predicting and controlling the behavior of other group members. This sociality hypothesis organizes previously inexplicable and disparate phenomena in a Darwinian framework and makes novel predictions about human choice. (shrink)

Most behavioral decision research takes place in carefully controlled laboratory settings, and examination of relationships between performance and specific real-world decision outcomes is rare. One prior study shows that people who perform better on hypothetical decision tasks, assessed using the Adult Decision-Making Competence (A-DMC) measure, also tend to experience better real-world decision outcomes, as reported on the Decision Outcomes Inventory (DOI). The DOI score reflects avoidance of outcomes that could result from poor decisions, ranging from serious (e.g., bankruptcy) to minor (...) (e.g., blisters from sunburn). The present analyses go beyond the initial work, which focused on the overall DOI score, by analyzing the relationships between specific decision outcomes and A-DMC performance. Most outcomes are significantly more likely among people with lower A-DMC scores, even after taking into account two variables expected to produce worse real-world decision outcomes: younger age and lower socio-economic status. We discuss the usefulness of DOI as a measure of successful real-world decision making. (shrink)

Residency training in the Netherlands is to be restructured over the coming years. To this end a general competence profile for medical specialists has been introduced. This profile is nearly the same as the Canadian CanMEDS 2000 model, which describes seven general areas of medical specialist competence, one of which is professionalism. In order to establish a training programme for residents and their instructors based on this competence, it is necessary to develop a vision that does justice to everyday medical (...) practice. The two most prevailing views of professionalism—as personal, or as a behavioural characteristic—fall short of this. Only when professionalism is understood as reflective professionalism does it encompass the fundamental contextuality of medical treatment. This means that the focus of training and assessment must be shifted to accountability for treatment. (shrink)

Este artículo afronta el concepto de “laicidad”. El primer paso es clarificar los distintos términos y sobre todo los conceptos que se usan en este argumento. Después se hace un recorrido por la historia del cristianismo sobre la laicidad, comenzando por el comportamiento del mismo Jesús. En la Iglesia se fue pasando de esta situación a la más rígida sacralización del cristianismo hasta convertirlo en una verdadera “religión”, aunque por encima de todas las demás. En este camino, después de siglos, (...) el Concilio Vaticano II ha superado la situación anterior de sociedad sacralizada, a la distinción y separación neta entre el plano social y el plano eclesial. Este cambio lleva a consecuencias claras y concretas tanto de puertas adentro de la Iglesia, como en su relación con la sociedad laica en que vive la propia institución eclesial como cada cristiano personalmente.

Partiendo de la invitación hecha por el Papa Juan Pablo II en su Carta Apostólica "Tertio Millennio Adveniente" a reflexionar sobre la estrecha relación existente entre los misterios de la Encarnación y de la Eucaristía (perspectiva central del Jubileo 2000: TM 55), este trabajo estudia en profundidad las claves bíblicas y teológicas desde las que estos dos misterios que se pueden ver y considerar. Entre las muchas claves desde las que sería posible leer e interpretar estos misterios, este trabajo ha (...) seleccionado seis de ellas, que perfectamente aplicables a ambos misterios, y que constituyen el hilo conductor de la presente reflexión: el trinitario, el pascual, la unidad, la presencia mutuamente vinculante y redentora, la plenitud y las claves marianas.

In 1999, da Silva, D'Ottaviano and Sette proposed a general definition for the term translation between logics and presented an initial segment of its theory. Logics are characterized, in the most general sense, as sets with consequence relations and translations between logics as consequence-relation preserving maps. In a previous paper the authors introduced the concept of conservative translation between logics and studied some general properties of the co-complete category constituted by logics and conservative translations between them. In this paper we (...) present some conservative translations involving classical logic, Lukasiewicz three-valued system L3, the intuitionistic system I1 and several paraconsistent logics, as for instance Sette's system P1, the D'Ottaviano and da Costa system J3 and da Costa's systems Cn, 1≤ n≤ω.

Abordamos en este trabajo la imagen de Dios que nos revela el cántico evangélico del Magnificat (Lucas 1, 46-55) y la imagen de María que en él aparece. Partiendo de su contexto en la obra de Lucas y de un breve análisis exegético del cántico, los autores profundizan en sus claves teológicas en relación con dos núcleos: la imagen de Dios y la figura de María introducida por el evangelista. El trabajo concluye con una propuesta de relectura del Magnficat acorde (...) con nuestro tiempo, centrada en su dimensión profética y liberadora. (shrink)

¿Quiénes son los laicos en la Iglesia? ¿Encajan en la estructura de la vida religiosa? Este artículo intenta responder a estas preguntas analizando el significado como la teoría y connotaciones prácticas de los legos para la vida del Inspectoría Salesiana de Córdoba (España) después del Concilio.

En la actualidad podemos observar –en algunos sectores cualificados de la Iglesia Católica– un tipo de interés por devaluar la fuerza reformista con la que el Papa Juan XXIII imprimió al Concilio Vaticano II desde su convocatoria (25 de enero de 1959). La celebración de este Concilio Ecuménico (1962-1965) provocó una ola de entusiasmo y optimismo dentro de la Iglesia, y no poca expectación en el resto del mundo. En el post-concilio encontraríamos luces y sombras. Incluso podemos escuchar voces (no (...) muy fuertes, pero desde instituciones significativas de la Iglesia) que indican que el concilio se equivocó al tomar ciertas posiciones reformistas dentro del cristianismo católico. Este artículo surge de este contexto y –declarando el Concilio Vaticano II como un regalo preciosode Dios a su Iglesia- desea ser una clara e inequívoca reivindicación de la “letra” y especialmente del “espíritu” que iluminaron este Concilio en la Iglesia Católica. La “letra” del Concilio sin su espíritu es un cuerpo muerto. El “espíritu” sin la letra, una fuerza verdaderamente ineficaz. (shrink)

The mobile phone has become part of our everyday lives with astonishing speed. Over four billion people now have access to mobile phones, and this number keeps increasing. Mobile media technologies shape how we communicate with each other, and relate to the world. This raises questions about their influence on identity. Medium-specific properties and user-practices challenge the idea that we understand ourselves through stories. It is proposed that the notion of play sheds new light on how technologies shape identities. The (...) mobile phone mediates identities on four play levels: we play on the mobile, with the mobile, through the mobile, and at the same time we are played by the mobile. Mobile media bring new freedom of movement. Yet at the same time they constrict us. In this dialectic we become moving circles. (shrink)

In this work we deal with a general class of spatially distributed periodic SIS epidemic models with two time scales. We let susceptible and infected individuals migrate between patches with periodic time dependent migration rates. The existence of two time scales in the system allows to describe certain features of the asymptotic behavior of its solutions with the help of a less dimensional, aggregated, system. We derive global reproduction numbers governing the general spatially distributed nonautonomous system through the aggregated system. (...) We apply this result when the mass action law and the frequency dependent transmission law are considered. Comparing these global reproductive numbers to their non spatially distributed counterparts yields the following: adequate periodic migration rates allow global persistence or eradication of epidemics where locally, in absence of migrations, the contrary is expected.

BackgroundThere is evidence that direct journal endorsement of reporting guidelines can lead to important improvements in the quality and reliability of the published research. However, over the last 20 years, there has been a proliferation of reporting guidelines for different study designs, making it impractical for a journal to explicitly endorse them all. The objective of this study was to investigate whether a decision tree tool made available during the submission process facilitates author identification of the relevant reporting guideline.MethodsThis was (...) a prospective 14-week before–after study across four speciality medical research journals. During the submission process, authors were prompted to follow the relevant reporting guideline from the EQUATOR Network and asked to confirm that they followed the guideline (‘before’). After 7 weeks, this prompt was updated to include a direct link to the decision-tree tool and an additional prompt for those authors who stated that ‘no guidelines were applicable’ (‘after’). For each article submitted, the authors’ response, what guideline they followed (if any) and what reporting guideline they should have followed (including none relevant) were recorded.ResultsOverall, 590 manuscripts were included in this analysis—300 in the before cohort and 290 in the after. There were relevant reporting guidelines for 75% of manuscripts in each group; STROBE was the most commonly applicable reporting guideline, relevant for 35% (n = 106) and 37% (n = 106) of manuscripts, respectively. Use of the tool was associated with an 8.4% improvement in the number of authors correctly identifying the relevant reporting guideline for their study (p < 0.0001), a 14% reduction in the number of authors incorrectly stating that there were no relevant reporting guidelines (p < 0.0001), and a 1.7% reduction in authors choosing a guideline (p = 0.10). However, the ‘after’ cohort also saw a significant increase in the number of authors stating that there were relevant reporting guidelines for their study, but not specifying which (34 vs 29%; p = 0.04).ConclusionThis study suggests that use of a decision-tree tool during submission of a manuscript is associated with improved author identification of the relevant reporting guidelines for their study type; however, the majority of authors still failed to correctly identify the relevant guidelines.

There is a widespread conviction that people distinguish two kinds of acts: on the one hand, acts that are generalisably wrong because they go against universal principles of harm, justice, or rights; on the other hand, acts that are variably right or wrong depending on the social context. In this paper we criticise existing methods that measure generalisability. We report new findings indicating that a modification of generalisability measures is in order. We discuss our findings in light of recent criticisms (...) of moral/conventional research. (shrink)
