Cet article décrit et analyse du point de vue de leurs évolutions majeures, les finalités des formations en alternance des maisons familiales rurales, une des principales institutions privées de l’enseignement agricole technique en France. Cette pédagogie de l’alternance est issue du syndicalisme agricole qui a défini les modes d’intervention des agents de formation, appelés les moniteurs. L’alternance, construite au départ contre l’enseignement primaire public, avait pour principal but de restaurer la famille paysanne en tant qu’instance éducative légitime, considérée comme détentrice (...) du monopole de la transmission des savoirs agricoles. Toutefois, à partir des années 1960, cette finalité initiale disparaît. Avec la massification scolaire, les formations en alternance jouent désormais un rôle d’école de la seconde chance oscillant entre une fonction de professionnalisation et une fonction de remédiation scolaire. Au cours d’une troisième période, identifiée à partir des années 1990, au moment de la création des maisons familiales urbaines, ces deux fonctions vont se rejoindre, ce dont témoigne l’évolution du rôle de moniteur : il devient un adulte référent et un « tuteur » pour des jeunes en difficulté se préparant à entrer dans la vie d’adulte.

In this paper we develop a differential analogue of o-minimal cell decomposition for the theory CODF of closed ordered differential fields. Thanks to this differential cell decomposition we define a well-behaving dimension function on the class of definable sets in CODF. We conclude this paper by proving that this dimension is closely related to both the usual differential transcendence degree and the topological dimension associated, in this case, with a natural differential topology on ordered differential fields.

Responding to serious environmental problems, requires urgent and fundamental shifts in our day-to-day lifestyles. This paper employs a qualitative, cross-cultural approach to explore people’s subjective self-reflections on their experiences of pro-environmental behavioral spillover in three countries; Brazil, China, and Denmark. Behavioral spillover is an appealing yet elusive phenomenon, but offers a potential way of encouraging wider, voluntary lifestyle shifts beyond the scope of single behavior change interventions. Behavioral spillover theory proposes that engaging in one pro-environmental action can catalyze the performance (...) of others. To date, evidence for the phenomenon has been mixed, and the causal processes governing relationships between behaviors appear complex, inconsistent and only partly understood. This paper addresses a gap in the literature by investigating accounts of behavioral spillover in three diverse cultural settings using qualitative semi-structured interviews. The analysis shows that while around half of participants overall who were questioned recalled spillover effects, the other half had not consciously experienced spillover. There were few significant differences across cultures, though some forms of spillover effects were reported more in some cultures than others. More environmentally-engaged participants across all three countries were significantly more likely to experience spillover than those who were less engaged. Accounts of within-domain spillovers were most commonly reported, mainly comprising waste, resource conservation and consumption-related actions. Accounts of between-domain spillover were very rare. Recollection of contextual and interpersonal spillover effects also emerged from the interviews. Our findings suggest that more conscious behavioral spillover pathways may be limited to those with pre-existing environmental values. Behavioral spillover may comprise multiple pathways incorporating conscious and unconscious processes. We conclude that targeting behavioral catalysts that generate more socially diffuse spillover effects could offer more potential than conventional spillover involving a single individual. (shrink)

The species concept is one of the oldest and most fundamental in biology. And yet it is almost universally conceded that no satisfactory definition of what constitutes a species has ever been proposed. The present article is devoted to an attempt to review the status of the problem from a methodological point of view. Since the species is one of the many taxonomic categories, the question of the nature of these categories in general needs to be entered into.

Dans la foulée des débats de bioéthique en France, l'Ecole Supérieure d'Ethique des Sciences de l'Institut catholique de Toulouse a organisé cinq grands débats éthiques en 2010-2011, en partenariat avec le monde industriel et universitaire, et qui sont ici rapportés. Le livre reprend les interventions des conférenciers et intervenants, présente de manière synthétique et pédagogique les débats qui ont suivi. et en propose une relecture. Cette dernière est faite en termes de défis que l'ensemble de la société est invité à (...) relever pour que les sciences et les techniques soient vraiment au service d'une société toujours plus humaine. Le livre souligne également l'impact des sciences et techniques sur les mentalités de nos contemporains et sur la manière de considérer la place de l'homme et le respect de la vie humaine. (shrink)

In [T. Brihaye, C. Michaux, C. Rivière, Cell decomposition and dimension function in the theory of closed ordered differential fields, Ann. Pure Appl. Logic .] the authors proved a cell decomposition theorem for the theory of closed ordered differential fields which generalizes the usual Cell Decomposition Theorem for o-minimal structures. As a consequence of this result, a well-behaving dimension function on definable sets in CODF was introduced. Here we continue the study of this cell decomposition in CODF by proving three (...) additional results. We first discuss the relation between the δ-cells introduced in the above-mentioned reference and the notion of Kolchin polynomial in differential algebra. We then prove two generalizations of classical decomposition theorems in o-minimal structures. More exactly we give a theorem of decomposition into definably d-connected components and a differential cell decomposition theorem for a particular class of definable functions in CODF. (shrink)

This book explores politics as a form of alchemy, understood as the transformation of entities through an alteration of their identities. Identifying this process as a common denominator of many political phenomena, such as communism, EU integration, mediatisation or globalisation, the author demonstrates not only the widespread presence of alchemical techniques in politics, but also the acceleration of their deployment. A study of the steady growth of power as it reaches a continuous and permanent stage, thus avoiding the inherent difficulties (...) connected with birth and death of political organisations and institutions, this volume reveals political alchemy to be a form of self-sustaining growth through sterile multiplication, devoid of meaning. Revealing both the integrative and disintegrative nature of a political process that, while appearing to work in the interests of all, in fact produces apathy, desperate mobilisation and despair by crushing concrete entities such as personality and tradition, Political Alchemy: Technology Unbounded will appeal to scholars of sociology and anthropology with interests in social theory and political thought.

Despite the availability of evidence-based treatment models for adolescent behavior problems, little is known about the effectiveness of these programs for adolescents with callous-unemotional traits. Defined by lack of empathy, lack of guilt, flattened affect and lack of caring, CU traits have been linked to long-term anti-social behavior and unfavorable treatment outcomes and might be negatively related to outcomes in evidence-based programs such as Functional Family Therapy. This study used a single-group pre-post evaluation design with a sample of 407 adolescents (...) receiving FFT to investigate whether outcomes in FFT are predicted by CU traits and to what extent reliable changes in CU traits can be observed. The results showed that although CU traits are related to increased problem severity at baseline, they predicted neither treatment dropout nor post-treatment externalizing behavior and family functioning. CU traits were related to diminished improvement ratings, in particular with respect to parental supervision. Reductions in CU traits were observed across the time of treatment, and these were most profound among adolescents with elevated levels of CU traits at baseline. Further research should investigate whether certain evidence-based treatment components are more suited for adolescents with CU, and if the addition of specific intervention elements for reducing CU-traits could further improve outcomes for this high-risk population.

In his Ph.D. thesis [7], L. van den Dries studied the model theory of fields with finitely many orderings and valuations where all open sets according to the topology defined by an order or a valuation is globally dense according with all other orderings and valuations. Van den Dries proved that the theory of these fields is companionable and that the theory of the companion is decidable .In this paper we study the case where the fields are expanded with finitely (...) many orderings and an independent derivation. We show that the theory of these fields still admits a model companion in the language Lequation image = {+, –, ·, D, <1, …, shrink)

The principle of democracy is one of equal dignity for all cultures. But today the relationship between culture and politics, though close, often appears tense and occasionally contradictory. The introduction to this issue of Diogenes sketches the work done by UNESCO in the frame of the 'Pathways of Thought' Programme, particularly relating to the way in which a pluralist identity is created in multicultural nations, and to the relationship between non-material heritage, democracy and the quest for new forms of governance.

A tissue is a geometrical, space-filling, random cellular network; it remains in this steady state while individual cells divide. Cell division is a local, elementary topological transformation which establishes statistical equilibrium of the structure. We describe the physical conditions to maintain stationary the epidermis (of mammals or of the cucumber), in spite of the fact that cells constantly divide and die. Specifically, we study the statistical equilibrium of the basal layer, a corrugated surface filled with cells, constituting a two-dimensional topological (...) froth. Cells divide and detach from the basal layer, and these two topological transformations are responsible for the stationary state of the epidermis. The topological froth is capable of responding rapidly and locally to external constraints, and is a good illustration of the plasticity of random cellular networks.Statistical equilibrium is controlled by entropy, both as a measure of disorder and as information, and is characterized by observable relations between average cell shapes and sizes. The technique can be applied to any random cellular network in dynamical equilibrium. Mitosis as the dominating topological transformation and the fact that the distribution of cell shapes is very narrow are the only inputs specific to biology. (shrink)
