An enactive and dynamical systems theory account of dyadic relationships

Many social relationships are a locus of struggle and suffering, either at the individual or interactional level. In this paper we explore why this is the case and suggest a modeling approach for dyadic interactions and the well-being of the participants. To this end we bring together an enactive approach to self with dynamical systems theory. Our basic assumption is that the quality of any social interaction or relationship fundamentally depends on the nature and constitution of the individuals engaged in these interactions. From an enactive perspective the self is conceived as an embodied and socially enacted autonomous system striving to maintain an identity. This striving involves a basic two-fold goal: the ability to exist as an individual in one's own right, while also being open to and affected by others. In terms of dynamical systems theory one can thus consider the individual self as a self-other organized system represented by a phase space spanned by the dimensions of distinction and participation, where attractors can be defined. Based on two everyday examples of dyadic relationship we propose a simple model of relationship dynamics, in which struggle or well-being in the dyad is analyzed in terms of movements of dyadic states that are in tension or in harmony with individually developed attractors. Our model predicts that relationships can be sustained when the dyad develops a new joint attractor toward which dyadic states tend to move, and well-being when this attractor is in balance with the individuals' attractors. We outline how this can inspire research on psychotherapy. The psychotherapy process itself provides a setting that supports clients to become aware how they fare with regards to the two-fold norm of distinction and participation and develop, through active engagement between client (or couple) and therapist, strategies to co-negotiate their self-organization.

A New theory for evaluating the number density of inclusions in films

A new formulation derived from thermal characters of inclusions and host films for estimating laser induced damage threshold has been deduced. This formulation is applicable for dielectric films when they are irradiated by laser beam with pulse width longer than tens picoseconds. This formulation can interpret the relationship between pulse-width and damage threshold energy density of laser pulse obtained experimentally. Using this formulation, we can analyze which kind of inclusion is the most harmful inclusion. Combining it with fractal distribution of inclusions, we have obtained an equation which describes relationship between number density of inclusions and damage probability. Using this equation, according to damage probability and corresponding laser energy density, we can evaluate the number density and distribution in size dimension of the most harmful inclusions.

Possible antigravity regions in F (R) theory?

We construct an F(R) gravity theory corresponding to the Weyl invariant two scalar field theory. We investigate whether such F (R) gravity can have the antigravity regions where the Weyl curvature invariant does not diverge at the Big Bang and Big Crunch singularities. It is revealed that the divergence cannot be evaded completely but can be much milder than that in the original Weyl invariant two scalar field theory. (C) 2014 The Authors.

Distanciamento teórico e engajamento prático: acerca da unidade entre atitude teórica e atitude prática a partir de um problema oriundo da hermenêutica filosófica

Desde os gregos antigos, sobretudo, desde Aristóteles, as assim chamadas ciências teoréticas, das quais se destaca a filosofia, têm sido caracterizadas como experiências de pura contemplação da essência última das coisas nelas investigadas. Por se tratar de uma experiência pura, nela não interviria nenhuma outra atitude diferente da própria atitude teorética; mais especificamente, a atitude teorética não apresentaria qualquer sinal de atitude prática, ou seja, qualquer sinal de interesse pela possível utilidade da coisa conhecida nem mesmo qualquer sinal de intenção para agir. Haja vista tal panorama geral, a presente tese almeja mostrar como a atitude teórica forma, na verdade, uma unidade com a atitude prática; como ela, a teoria, precisa ser, sobretudo, uma ação genuinamente prática. Para tanto, a tese parte de uma interpretação crítica do projeto filosófico de Gadamer que reivindica para a hermenêutica o título de filosofia prática, que, no fundo, se trata de uma tentativa de reunir teoria e prática em uma só experiência. Só então, a tese procura mostrar como quem faz a experiência teórica, já que precisa pensar na linguagem, se encontra em um âmbito essencialmente plural, onde, portanto, há muitos outros dos quais, inclusive, ele até mesmo depende para concretizar a possibilidade de falar. Assim, a tese estabelece as condições para revelar a necessidade de quem faz a experiência teorética de se engajar em um amplo jogo histórico, que o compele a agir não só eticamente em relação aos outros como também politicamente em conjunto com eles.
