Łukasiewicz-Moisil Relation Algebras

We introduce Łukasiewicz-Moisil relation algebras, obtained by considering a relational dimension over Łukasiewicz-Moisil algebras. We prove some arithmetical properties, provide a characterization in terms of complex algebras, study the connection with relational Post algebras and characterize the simple structures and the matrix relation algebras.     

Relational-oriented character analysis

Referring to the diversity of psychoanalysis of today, a position called relational-oriented character analysis is discussed. It is stated that relation and character as concepts refer to different and partly contradictory points of view in psychoanalysis, the first one emphasising mobile, dynamic aspects of personality, the second underlining stable, structural aspects. The principle aim of the article is to argue how the two perspectives can be theoretically combined in an overriding object-relational (two-person) conception and to discuss some implications for analytic technique. Finally, convergences and differences with other positions or schools in contemporary psychoanalysis are suggested.     

Interfacial waves between two magneto-electro-elastic half-spaces with magneto-electro-mechanical imperfect interface

The propagation of shear horizontal waves between the interface of two magneto-electro-elastic materials with an magneto-electro-mechanical imperfect contact has been studied. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and an inductor, respectively. A general expression for the dispersion relation is given in an explicit form. Some limit cases are analysed in detail. The influence of imperfect contacts is shown in some numerical results.     

Extreme damping in compliant composites with a negative-stiffness phase

Compliant composite unit cells were made with negative stiffness constituents. Flexible silicone rubber tubes were incorporated in a post-buckled condition to achieve negative stiffness. Large peaks in the mechanical damping tan delta were observed in these systems. Maximum damping was orders of magnitude in excess of the material damping of the silicone rubber.     

Freud and narcissism: Developing links for inclusion of the ‘object’

Abstract

The problematic of narcissism in the way Freud visualized forces us to acknowledge the dualism of drives inside the subject; the object relations theory then builds up on the inherent need and the structuring potential of the object. The paper traces the growth of this concept in Freud's thinking in a bid to show how the object's otherness is not fully metabolized within the Freudian corpus. On the other hand, recent criticisms of object relations theory point to the perfunctory role ascribed to Freud's most radical discovery of the dualism of drives. Winnicott, Laplanche and Green have all developed theories that have provided pertinent rejoinders to the problematic of narcissism and object relations. The paper discusses how deconstructing and “going back over Freud” helps us to redefine object relations and give the drive functioning due importance. Hence the main thesis of the paper – that of narcissism – reveals the decentered subject's tussle with itself and with the alienness emanating from the object's otherness. If used creatively, ideas such as “otherness”, “objectalizing function” and Green's conceptualization of the clinical significance of negative and positive narcissism then seek to enrich the theorization on narcissism.     

Formation par alternance : expérience scolaire et rapport à l’apprendre chez des apprentis de niveau V et leurs maîtres d’apprentissage

This qualitative research in line with a socio-constructivist approach of the relation to knowledge aims at studying the conditions of efficiency of apprenticeship (training centre/working place) for wage-earning apprentices with a level V. The thematic analysis of 38 interviews (19 apprentices and 19 apprenticeship masters) reveals that apprentices and apprenticeship masters develop some similar schooling experience and relations to learning based on a massive rejection for any schooling form of transmission. We thus show that an apprenticeship based on work and study can offer young people the opportunity to reinvest their relation to learning but only under the conditions of finding ways to escape the circle of school condemnation. These young people must also be able to find in this system the necessary conditions which will give a meaning to their experience of apprentices.     

The GROOP effect: groups mimic group actions

Research on perception–action links has focused on an interpersonal level, demonstrating effects of observing individual actions on performance. The present study investigated perception–action matching at an inter-group level. Pairs of participants responded to hand movements that were performed by two individuals who used one hand each or they responded to hand movements performed by an individual who used both hands. Apart from the difference in the number of observed agents, the observed hand movements were identical. If co-actors form action plans that specify the actions to be performed jointly, then participants should have a stronger tendency to mimic group actions than individual actions. Confirming this prediction, the results showed larger mimicry effects when groups responded to group actions than when groups responded to otherwise identical individual actions. This suggests that representations of joint tasks modulate automatic perception–action links and facilitate mimicry at an inter-group level.
