The diagnosis of HIV infection is the point of entry for treatment and prevention services, yet many infected persons in both developed and developing countries remain undiagnosed. To reduce the number of undiagnosed infections, a variety of expanded testing policies have been recommended, including opt-out testing. This testing model assumes that in populations of increased HIV prevalence, voluntary testing should be offered to all patients seen in healthcare settings and performed unless patients specifically decline. While this approach raises ethical issues (...) concerning “voluntariness”, access to care, and stigma, the potential benefits of opt-out testing far outweigh its potential adverse effects. (shrink)

This paper suggests a framework for determining the ethicality of disguised and obtrusive advertising. While most discussions of advertising ethics deal with deception or fraud, the proposed framework is based on the way messages are presented to audiences. Suggestions for measurement and future research are given.

To reduce the spread of the human immunodeficiency virus (HIV), Granich et al. 1 ( 2009 ) have proposed a new strategy for universal voluntary HIV testing immediately followed by antiretroviral therapy. Although this proposal is likely to benefit the partners of those affected and thus promote public health, it is by no means clear that it benefits the infected people themselves and indeed it may be harmful. Since the proposal involves an intervention that is not clinically indicated, it falls (...) foul of the normal ethical standards of clinical medicine, which is to act in the best interests of patients. Neither is it a measure that would be imposed under the protection of public health law on people who are seen as representing such danger to others that significant restrictions in liberty are appropriate. Thus, the proposal represents a third category of public health measure. We argue that a coherent ethical framework including a robust process is appropriate to proposals of this kind and that medical research offers a useful model since some research, like this proposal, is motivated not by the interests of the individual participants but by the common good. We outline some possible elements of such an ethical framework. (shrink)

Results of an agent-based computer simulation of the evolution of diploid sexual organisms showed that several mate selection strategies confer much higher average fitness to the simulated populations, and higher evolutionary stability to the alleles coding for these strategies, than random mating. Strategies which select for ''good genes'' were very successful, and so were strategies based on assortative mating. The results support the hypothesis that mating is not likely to be random in nature and that the most successful mate selection (...) strategies are those based on assortative mating or on advantageous genes.

This study investigated students’ perceptions of ethical organizational climates, attitudes towards ethical issues, and the perceived relationship between ethical behavior and success in business organizations. Comparisons were made between the attitudes of these future managers with previously published studies of Russian managers’ attitudes. A survey of 100 business students in three Moscow universities showed that their attitudes toward ethical behavior were more negative than those of Russian managers. No significant differences were found in the perceptions or attitudes of students who (...) had attended an ethics course and those that did not. The implications for both managers and researchers were reported. (shrink)

The concept of altruism is used in very different forms by computer scientists,economists, philosophers, social scientists, psychologists and biologists. Yet, in order to be useful in social simulations, the concept altruism requires a more precise meaning. A quantitative formulation is proposed here, based on the cost/benefit analysis of the altruist and of society at large. This formulation is applied in the analysis of the social dynamic working of behaviors that have been called altruistic punishments, using the agent based computer model (...) Sociodynamica. The simulations suggest that altruistic punishment on its own cannot maintain altruistic behaviors. Altruistic behavior is sustainable in the long term only if these behaviors trigger synergetic forces in society that eventually make them produce benefits to most individuals. The simulations suggest however that altruistic punishment may work as a social investment , and is thus better called decentralized social punishment. This behavior is very efficient in enforcing social norms. The efficiency of decentralized social punishment in enforcing norms was dependent on the type of labor structured of the virtual society. I conclude that what is called altruistic punishment emerges as a type of social investment that can evolve either through individual and/or group selection, as a successful device for changing or enforcing norms in a society. Social simulations will help us in better understanding the underlying dynamic working of such devices. (shrink)

Advances in multiagent simulation techniques make it possible to study more realistic dynamics of complex systems and allow evolutionary theories to be tested. Here I use simulations to assess the relative importance of reproductive systems (haplodiploidy vs. diploidy), mate selection (assortative mating vs. random mating) and social economics (pay-off matrices of evolutionary games) in the evolutionary dynamics leading to the emergence of social cooperation in the provision of parental care. The simulations confirm that haplo-diploid organisms and organisms mating assortatively have (...) a higher probability for fixing alleles and require less favorable conditions for their fixation, than diploids or organisms mating randomly. The simulations showed that social behavior was most likely to emerge a) when the cost for parental investment was much lower than the benefits to the offspring, b) when cooperation improved synergistically the fitness of offspring compared to the corresponding egoistic behavior and c) when alleles coding for altruistic or social behavior could be rapidly fixed in the population, thanks to mechanisms such as haplo-diploidy and/or assortative mating. Cooperative social behavior always appeared if sociality conferred much higher fitness gains compared to non cooperative alternatives suggesting that the most important factors for the emergence and maintenance of social behavior are those based on energetic or efficiency considerations. The simulations, in congruence with the scant experimental evidence available, suggest that economic considerations rather than genetic ones are critical in explaining the emergence and maintenance of sociality.

Using computer simulations I studied the simultaneous effect of variable environments, mutation rates, ploidy, number of loci subject to evolution and random and assortative mating on various reproductive systems. The simulations showed that mutants for sex and recombination are evolutionarily stable, displacing alleles for monosexuality in diploid populations mating assortatively under variable selection pressure. Assortative mating reduced excessive allelic variance induced by recombination and sex, especially among diploids. Results suggest a novel adaptive value for sex and recombination. They show that (...) the adaptive value of diploidy and that of the segregation of sexes is different to that of sex and recombination. The results suggest that the emergence of sex had to be preceded by the emergence of diploid monosexual organisms and provide an explanation for the emergence and maintenance of sex among diploids and for the scarcity of sex among haploid organisms.

Harold Jaffe argues that we should adopt opt-out testing for HIV. There are paternalistic and utilitarian arguments for such an approach. In this commentary I draw attention to some similarities between his arguments and debates about opt-out systems of organ donation. I argue that the status quo bias provides both part of the reason that opt-out approaches work, and an explanation for why such approaches are sometimes resisted.

Dan Jaffé | : Cet article se propose d’étudier les conceptions talmudiques relatives à la croyance chrétienne en la conception et en la naissance virginale de Jésus. L’approche consiste principalement en une étude philologique et historique du cognomen ben Pantera affilié à Jésus dans de nombreux textes talmudiques principalement tannaïtiques. On propose de voir dans le nom ben Pantera une raillerie à l’encontre de la croyance chrétienne en la conception et en la naissance virginale de Jésus. L’accusation d’union illégitime énoncée (...) et véhiculée en monde juif ainsi qu’en monde païen se retrouve dans la littérature talmudique. Le christianisme y est souvent assimilé à la séduction exercée par la prostitution. Ainsi, c’est à un même univers conceptuel qu’il convient de se référer dans l’étude de cette question : la relation dialectique entre l’attirance exercée par le christianisme et celle exercée par la prostituée, dans le processus historique de séparation entre juifs et chrétiens. | : This article proposes a philological and historic analysis of the Talmudic name Ben Pantera. It is suggested that this ancient expression has to be understood as corresponding to a period in which the Jews wished to think of Christianity, choosing the person of Jesus as an emblematic figure of this reality. The expression Ben Pantera expresses mockery and even scorn towards Jesus. It must be placed back in a period in which, on account of the doctrinal controversies between Jews and Christians, the two religions had consummated a Parting of the Ways and acknowledged each other as rivals. Thus, Ben Pantera appears to be the oldest mention of Jesus in the Talmudic literature. (shrink)

This article explores the role of the Deaf child as peer educator. In schools where sign languages were banned, Deaf children became the educators of their Deaf peers in a number of contexts worldwide. This paper analyses how this peer education of sign language worked in context by drawing on two examples from boarding schools for the deaf in Nicaragua and Thailand. The argument is advanced that these practices constituted a child-led oppositional pedagogy. A connection is drawn to Freire’s (1972) (...) theory of critical pedagogy. Deaf children’s actions as peer educators are framed as an act of resistance towards the oppression of their language and culture. A contrast is drawn between oralist pedagogy that is historically associated with punitive practices and didactic methods and the experiential and dialogic interaction that characterised peer learning of sign languages. The argument is made that the peer teaching and learning processes enabled the self-actualisation of the Deaf children whereas the oralist methods were based on a deficit model that focused on modifying deaf children according to the norms of hearing society. The implications of this for current policy and practice are inferred to be about access to sign languages and the importance of Deaf communities in deaf children’s education. The argument is made that space needs to be created for deaf children to engage in peer learning. (shrink)
