There have been two main lines in the literature on restricted games: the first line was started by Myerson (1977) that studied graph-restricted games an the second one was initiated by Faigle (1989). The present paper provides a unified way to look on the literature and establishes connections between the two different lines on restricted games. The strength and advantages of this unified approach becomes clear in the study of the inheritance of the convexity from the game to the restricted (...) game where an interesting result by Nouweland and Borm (1991) on the convexity of graph-restricted games is turned into a direct consequence of the corresponding result by Faigle (1989), by means of this relation.

Medical professionals are a community of highly educated individuals with a commitment to a core set of ideals and principles. This community provides both technical and ethical socialization. The ideal physician is confident, empathic, forthright, respectful, and thorough. These ideals allow us to define broadly "the excellence" of being a physician. At the core of these ideals is the ability to be empathic. Empathy exhibits itself in attributes of an individual's moral character and also in actions that actualize and support (...) communal life. Empathy, however, can be diminished or even lost and must be nurtured on an ongoing basis. The development of ethical physicians is strongly linked to experiences in the training period. Moral traits are situation-sensitive psychological and behavioral dispositions. The clinical environment of medical training programs can be so intense as to lead to conditions that may actually deprofessionalize trainees. Creating a clinical environment that is ethically nurturing and sustaining is an indispensable component of practicing medicine. (shrink)
In ecology, if the considered area or space is large, the spatial distribution of individuals of a given plant species is never homogeneous; plants form different patches. The homogeneity change in space or in time (in particular, the related change-point problem) is an important research subject in mathematical statistics. In the paper, for a given data system along a straight line, two areas are considered, where the data of each area come from different discrete distributions, with unknown parameters. In the (...) paper a method is presented for the estimation of the distribution change-point between both areas and an estimate is given for the distributions separated by the obtained change-point. The solution of this problem will be based on the maximum likelihood method. Furthermore, based on an adaptation of the well-known bootstrap resampling, a method for the estimation of the so-called change-interval is also given. The latter approach is very general, since it not only applies in the case of the maximum-likelihood estimation of the change-point, but it can be also used starting from any other change-point estimation known in the ecological literature. The proposed model is validated against typical ecological situations, providing at the same time a verification of the applied algorithms. (shrink)
Abstract This article describes a programme of educational intervention aimed at the development of prosocial?altruistic behaviour, and presents a study which evaluated its efficacy. The sample comprised 110 subjects, aged between 10 and 12 years, from four class?groups. The intervention, which consisted of a series of activities intended to encourage empathy, perspective?taking, having the concept of a person, and co?operation, was carried out by the teacher?tutor of each group in 15 weekly sessions. The pre?test/post?test comparisons showed a significant increase in (...) prosocial??altruistic behaviour (measured by a sociogram on ?Consoling and Defending? behaviour and a questionnaire on Prosocial behaviour), as well as an improvement in the capacity for perspective?taking and in the climate in the classroom.

Aquinas’s eudaimonism is normally interpreted as twofold in the sense of it dividing into the imperfect, natural happiness of Aristotle and the perfect, supernatural happiness of Augustine. I argue in this work that Aquinas is logically committed to a third type of happiness that, in light of the standard view, rendershis eudaimonism threefold. The paper begins with an overview of the standard twofold model of Aquinas’s eudaimonism; it then turns to the model’s logicalproblem whose solution requires the postulation of a (...) third type of happiness. In the second part of the paper, two clarificatory issues are addressed, several objections are considered, and in closing, I explain why Aquinas’s commitment to a third type of happiness offers the Christian wayfarer grounds for a new optimism.

This paper explores the way in which Agamben takes part in the dialogue on “impolitical communities” that was inaugurated by J. L. Nancy and was soon followed by authors like M. Blanchot, J. Derrida and R. Esposito, among others. Although Agamben’s ontological exploration of ‘whatever being,’ followed later by the political idea of form-of-life, are still very close particularly to Nancy’s work, the article will show in which ways Agamben’s view of a political coming community explores different paths and moves (...) in unusual registers, that help to understand in new ways the kind of inoperativeness involved in a contemporary rethinking of community. The notion of experience of thought as potentiality and its relationship to that “tiny displacement” of the world which Agamben seems to connect with his idea of a coming community will play a central role in the analysis.

On a basic level, "cyberpsychology" refers to the comparison of the mind with different kinds of machines. This multidisciplinary collection brings together essays by leading psychologists and cultural theorists working in the spheres of technology and psychology to explore links between popular culture, technoscience, feminism and politics. Tracing historical and contemporary lines of argument around the fascination between different forms of psychological and machine culture, contributors articulate "cyberpsychological" reflections on contemporary crises in psychology with emerging technologies of the self. The (...) volume offers challenging perspectives and insights to anyone interested in the connections between psychology and technological developments in the information age. (shrink)
There is a constructive method to define a structure of simple k -cyclic Post algebra of order p , L p , k , on a given finite field F ( p k ), and conversely. There exists an interpretation Φ 1 of the variety $${\mathcal{V}(L_{p,k})}$$ generated by L p , k into the variety $${\mathcal{V}(F(p^k))}$$ generated by F ( p k ) and an interpretation Φ 2 of $${\mathcal{V}(F(p^k))}$$ into $${\mathcal{V}(L_{p,k})}$$ such that Φ 2 Φ 1 ( B ) (...) = B for every $${B \in \mathcal{V}(L_{p,k})}$$ and Φ 1 Φ 2 ( R ) = R for every $${R \in \mathcal{V}(F(p^k))}$$. In this paper we show how we can solve an algebraic system of equations over an arbitrary cyclic Post algebra of order p, p prime, using the above interpretation, Gröbner bases and algorithms programmed in Maple.

Roger Boscovich, belonging to XVIII century, halfway from Newton to Faraday, is traditionally considered as a newtonian philosopher. Nevertheless, following Berkson’s suggestion, he could be a Field Theory forerunner. In this work, we will try to go on with the idea of this suggestion in order to show this possible Boscovich’s contribution.
The agro-food domain in Europe is characterized by the appearance of recurrent unwanted surprises. These events, although causing obvious physical consequences, in essence depart from the expectations of the society. We argue that this unstable situation is best understood as an identity crisis of agriculture rather than as a contingent crisis of a specific economic sector. Thus the present agro-food crisis is in fact a crisis of identity. This is clearly reflected by the cohabitation within the agro-food policy domain of (...) different, often contradictory, policy discourses, namely: free tradism, multifunctionality, and agroecology. All of them try to impose their particular visions. All of them struggle to issue the policy measures they conceive as appropriate. (shrink)
It is always possible to construct a real function f, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that f(X) and f(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence (...) of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox. (shrink)

In a recent Mind & Society article, Evans (2005) argues for the social and communicative function of conditional statements. In a related article, we argue for satisficing algorithms for mapping conditional statements onto social domains (Eur J Cogn Psychol 16:807â823,2004). The purpose of the present commentary is to integrate these two arguments by proposing a revised pragmatic cues algorithm for pragmatic conditionals.
