Keynes e o conceito de capital: reflexões epistemológicas a respeito das premissas sraffianas da teoria geral

Keynes and the concept of capital: some epistemological observations in regard to the Sraffian premises of the General Theory. This article aims to examine the conception of the nature of capital used by Keynes in the General Theory, to show to what extent this concept is similar to Sraffa's conception, and to highlight the implications related to this concept, in terms of structural instability. So I will study the mechanisms that explain the investment decision in an environment with strong uncertainty, the modalities of aggregation of different generations of capital and the instability of equilibrium. The convergence between the keynesian and the Sraffian approaches comes from this common conception of capital. Finally, i will examine the implications in regard to the structure of the aggregate models.

Henri Bergson e a simbiose cognitivo-psíquica na relação subjetividade & trabalho

The main purpose of this paper is to amplify the current theoretical scenario of "Mental Health and Work" area, according to the Henri Bergson's philosophy and his concepts of perception, cognition, duration, psychic life, time and subjectivity. This theoretical-philosophical article aims to shed new light on the relations between philosophy of mind and present-day efforts toward a scientific theory of cognition, with its complex structure of theories, hypotheses and disciplines. There is in this paper a new approach to understand the contemporary cognitive sciences in a kind of phenomenological investigation initiated by Husserl's phenomenology. The methods employed were the systematic review and adaptation of Bergson's concepts, and its naturalization in the actual context of epistemological and ontological principles of cognitive sciences, to phenomenological analysis of "work-mental health" links. The current contributions of the Husserl's Phenomenology were used to understand the relations between mental health and work. There are also references to philosophy applied in contemporary cognitive sciences based on Bergson's theoretic-philosophical proposal.
