Modernidade e pós-modernidade: em busca do sentido da vida atual

This paper refl ects on a set of themes that are part of the contemporary agenda. The article contrasts modernity and post-modernity to discuss the “new sociology” which is dedicated to interpret the world and the way of life derived from the digital revolution and an intense capitalist globalization. Accepting some of the metaphors and concepts developed by this sociology, the paper argues that the world suggests much more than the image of a “radicalized modernity”, in which the dynamics of the past collide and combine with dynamics that are coming into existence, forming a plural, uneven, and surprisingly fast system.

O trabalho como dispositivo de atenção em saúde mental: trajetória histórica e reflexões sobre sua atual utilização

The partnership between Mental Health (MH) and work is present throughout the history of psychiatry. Capitalist society has used and uses the fitness or unfitness for work not only as one of the elements to the definition of "normality", but also as a treatment strategy. In this perspective, one can find a position healing and, more recently, a different proposal put forward by the psychiatric reform that considers also make / produce, the construction of meaning in the work as crucial for subjectivity. This sense is present in therapeutic workshops that seek to value the uniqueness, not to override the differences. The objective of this paper is to reflect on the relationship between Attention in SM / Work. Initially presents three theses, from which this relationship is built historically: 1 - Work as a means of avoiding idleness returning productively to society; 2 - Work as a healing practice, from the prescription, and 3 - Work as a strategy for care and social inclusion. Below, we discuss some questions about therapeutic workshops and income generation in the mental health care as a device for attention and social inclusion.

Escola, seu fim e o ressurgimento da educação: o paradoxo da subjetividade no saber atual

O sistema educativo passa por um processo da institucionalização do saber. Qualquer forma de aprendizado que não seja subjetivado pelo “saber-escola” é automaticamente desacreditada, tudo isso em virtude da sacralização da escola e de sua demanda. Os colégios promovem uma educação doutrinária e alienante do projeto de vida da comunidade a que se destina, por isso há que enfatizar que estes possuem caráter disciplinador semelhante ao que ocorrem em instituições como as cadeias, manicômios. Através da apreensão do parco poder do saber nas mãos dos dirigentes institucionais, os alunos são transformados em “objetos-sujeito”, alvos de novas técnicas e ações que os desapropriam do direito de questionamento. Muitos autores – Paulo Freire, Ivan Illich, militaram em prol da emancipação das comunidades e de formas de aprendizagem autodirigidas e que promovessem a leitura e apreensão do mundo, efetivando troca de habilidades e o retorno das coletividades. São esses agentes políticos que norteiam essa revisão bibliográfica, de caracteres quiméricos para muitos, mas imprescindível para o retorno da educação que não se encontra apenas nas paredes da arquitetura panóptica dos locais instituídos como educacionais, mas sim em todas as situações que subjetivam os indivíduos ao longo de toda sua vida.

Since its birth, going on that point until your actuation and direct and indirect interplay in today's society from maturational form. Taking the concept of researchers' theory like Piaget.

A política externa estadunidense no atual quadro político sul-americano

The central thesis that we aim to survey in this paper is that the present South-American political scene has required of the American imperialism a strategical redesign, in the sense of the neutralization, weakening and, if it is possible, destruction of regional political experiences/tendencies not aligned to its foreign politics. Under the mask of the defense of democracy and beneath the argument that Latin American "market oriented politics" are at stake, due to questions that goes back from the "delin-quency" —in Mexico—, the global terrorism, the organized international crime up to the worldwide drug traffic, the global strategy of American imperialism then sets up the definition of a new doctrine of preventive war that justifies the utilization of hard power against any country, in the name of its own defense. At the heart of the question what —actually— is in the agenda is the defense (and reproduction) of the benefits of its multinationals corporations and financial capital, by means of the international sub-traction of profitable assets, such as financial, energetic, communicational and natural resources, in addition to the domination of local markets, beyond facilitating capital flee amongst others.
