In Multi Agent Systems it is often the case that individual preferences are not compatible and coalitions compete to achieve a given result. The paper presents a language to talk about the conflict between coalitional choices and it expresses deontic notions to evaluate them. We will be specifically concerned with cases where the collective perspective is at odds with the individual perspective.

Networks for the exchange and/or sharing of genetic data are developing in many countries. We focus here on the situations in the US and France. We highlight some recent and remarkable differences between these two countries concerning the mode of access to, and the storage and use of genetic data, particularly as concerns two-sided markets and dynamic consent or dynamic electronic informed consent. This brief overview suggests that, even though the organization and function of these two-sided markets remain open to (...) criticism, dynamic e-IC should be more widely used, especially in France, if only to determine its real effectiveness.

"Life is full of absurdities, and human misperception of such absurdities leads to a state of unrest and fear that require meaning and direction for a happy life. F. Pasqualino addresses here samples of existential absurdities, and discusses solutions offered: Taoism offers in its paradoxes a natural self-help resource. Buddhism offers a natural wisdom that is informed by a supernatural impersonal Absolute. Hinduism offers a plethora of personal gods who embody the impersonal Absolute. The Judeo-Christian-Islamic wisdom teaches a personal Absolute (...) God whose being is distinct from, but involved with human and non-human beings. The unifying feature of these wisdoms is: Obedience to, and love of, the Absolute can rectify human misperception of life's absurdities, dissipate fear, and provide meaning, value and a serene life. Jesus Christ, the incarnate Absolute in Christian theology, chose to become an exemplar innocent victim for love, thus giving the most absurd but victoriously redeeming love that provides a new and sublime perspective on life's absurdities. G. Lahood's translation and commentary make the Italian masterpiece available to an English-speaking audience"--. (shrink)

The presence of fetal cells has been associated with both positive and negative effects on maternal health. These paradoxical effects may be due to the fact that maternal and offspring fitness interests are aligned in certain domains and conflicting in others, which may have led to the evolution of fetal microchimeric phenotypes that can manipulate maternal tissues. We use cooperation and conflict theory to generate testable predictions about domains in which fetal microchimerism may enhance maternal health and those in which (...) it may be detrimental. This framework suggests that fetal cells may function both to contribute to maternal somatic maintenance (e.g. wound healing) and to manipulate maternal physiology to enhance resource transmission to offspring (e.g. enhancing milk production). In this review, we use an evolutionary framework to make testable predictions about the role of fetal microchimerism in lactation, thyroid function, autoimmune disease, cancer and maternal emotional, and psychological health.Also watch the Video Abstract.

A fundamental problem in game theory is the possibility of reaching equilibrium outcomes with undesirable properties, e.g., inefficiency. The economics literature abounds with models that attempt to modify games in order to avoid such undesirable properties, for example through the use of subsidies and taxation, or by allowing players to undergo a bargaining phase before their decision. In this paper, we consider the effect of such transformations in Boolean games with costs, where players control propositional variables that they can set (...) to true or false, and are primarily motivated to seek the satisfaction of some goal formula, while secondarily motivated to minimise the costs of their actions. We adopt preparation sets as our basic solution concept. A preparation set is a set of outcomes that contains for every player at least one best response to every outcome in the set. Prep sets are well-suited to the analysis of Boolean games, because we can naturally represent prep sets as propositional formulas, which in turn allows us to refer to prep formulas. The preference structure of Boolean games with costs makes it possible to distinguish between hard and soft prep sets. The hard prep sets of a game are sets of valuations that would be prep sets in that game no matter what the cost function of the game was. The properties defined by hard prep sets typically relate to goal-seeking behaviour, and as such these properties cannot be eliminated from games by, for example, taxation or subsidies. In contrast, soft prep sets can be eliminated by an appropriate system of incentives. Besides considering what can happen in a game by unrestricted manipulation of players’ cost function, we also investigate several mechanisms that allow groups of players to form coalitions and eliminate undesirable outcomes from the game, even when taxes or subsidies are not a possibility.

Significant amounts of wealth have been exchanged as part of marriage settlements throughout history. Although various models have been proposed for interpreting these practices, their development over time has not been investigated systematically. In this paper we use a Bayesian MCMC phylogenetic comparative approach to reconstruct the evolution of two forms of wealth transfers at marriage, dowry and bridewealth, for 51 Indo-European cultural groups. Results indicate that dowry is more likely to have been the ancestral practice, and that a minimum (...) of four changes to bridewealth is necessary to explain the observed distribution of the two states across the cultural groups.

The essay intends to revisit certain phenomenological themes present in the theoretical work of Pierre Schaeffer, based on his most important and influential book: the Traité des objets musicaux. A French engineer and composer, Schaeffer was the initiator – from the point of view of its musical practice, and its theoretical analysis – of one of the most important musical avant-gardes of the 20th century, musique concrète. The objective of the article will be to consider Schaeffer’s main reference – the (...) phenomenology of Edmund Husserl – and suggest that Maurice Merleau-Ponty’s phenomenology could be a prism that helps to understand and expand the heterogeneous and incomplete research project the French composer documented extensively in his writings.

The increasing concern about visual representation in science has been usually converged on representations – photographs, diagrams, graphs, maps –, while instruments of visualization have been usually neglected, even because of the concrete difficulty to grasp their effects on visualization. In this regard, the questions and concepts formulated in the debate on digital visualization deserve here as a starting point to analyze the change in instrumental mediation triggered by the introduction of computer-assisted imaging technologies in those laboratories that traditionally have (...) used and still use microscopes. Empirical materials gathered during an ethnographic investigation of Italian cytogenetics labs are here presented to show the visual spaces provided by microscopes and digital systems as activity fields, which are inhabited by and suggest in an either divergent or complementary way specific practices, materials, organizations, epistemological orientations and aesthetical preferences.

Questo saggio si propone di analizzare alcune istanze della _ Material Engagement Theory _ (MET) proposta da Lambros Malafouris nelle sue intersezioni con la filosofia speculativa di Alfred North Whitehead. Malafouris non fa infatti riferimento alla filosofia speculativa come semplice supporto delle sue teorie ma individua piuttosto una serie di problemi comuni all’impostazione MET e alla filosofia dell’organismo di Whitehed, che vertono sostanzialmente attorno al rapporto tra _ noesis _ e _ praxis _. Nel dettaglio, il testo si soffermerà sulle (...) modalità attraverso cui la teoria MET rimette in discussione, in modo originale e fecondo, il rapporto tra teoria e prassi, riattualizzando il peculiare modo con cui Whitehead intende il concetto di α ἴ σθησ ῐ ς.

El artículo aborda la carta 93 de san Agustín. Analiza los argumentos rogatistas contra el "compelle intrare", la eclesiología que subyace en ellos, el contexto sociohistórico del uso de la violencia para imponer la ley, así como la evolución agustiniana al interpretar el "compelle intrare".

As the median age of practicing physicians increases, ethical dilemmas due to age-related cognitive decline among clinicians will become ever more pressing. Compelling data show that despite acknowledgement of their duty to protect the public, physicians often fail to report themselves, their colleagues, or their physician-patients when cognitive decline appears to impact medical practice adversely. As such, efforts to educate physicians about ethical obligations and various tactful methodologies to report themselves or others seem ineffective. Illustrated by a case report of (...) age-related cognitive decline in a practicing physician, practical recommendations are made both to develop and validate cognitive screening in middle-aged physicians, presumably before the onset of age-related cognitive decline.

In this paper we introduce a variational principle from which the fundamental equations of classical physics can be deduced. This principle permits a sort of unification of the gravitational and the electromagnetic fields. The basic point of this variational principle is that the world-line of a material point is parametrized by a parameter a which carries some physical information, namely it is related to the rest mass and to the charge. In particular, the (inertial) rest mass will not be a (...) property of a material point, but it will be a constant of the motion which is determined by the initial conditions. In this framework the equality between the inertial and gravitational mass can be deduced. (shrink)

In some circumstances, scientists of the same discipline visualize and view differently the same scientific object. The question of representational difference , which has usually been connected to scientific revolutions or controversies, is framed here using the concept of “style,” addressing the plurality of scientific traditions within a well-established scientific field. Using ethnomethodology we will examine the divergences of representational practices that, beyond the apparent consensus of a scientific community, are present throughout the procedure of chromosomes preparation. The ethnographic data (...) was gathered through participant observation and in-depth interviews in several Italian clinical cytogenetic laboratories. The concept of style emerges through the examination of the two alternate, and sometimes conflicting, ways of configuring the complex texture of practice, instrumental mediation, epistemic virtues, and expertise involved in scientific representation of chromosomes. Resonating with the recent debate on objectivity, it tries to articulate the concept of “epistemic virtue” outside an internalised scientific self through an aesthetic, analytical, instrumental, and ontological preferences in the current manners to produce and see the same research object.
