Este artículo considera problemas del análisis de discurso contemporáneo referidos a los siguientes tópicos: su foco en la conversación cotidiana, las secuencias formales, la explicación correcta y la segregación disciplinaria. Problemas que replican dificultades generales que muestra la disciplina de la psicología, tales como la mirada puesta sobre aquellos que están fuera de su dominio, el reduccionismo a nivel del individuo, la abstracción de la conducta y los procesos cognitivos, los reclamos a la autoridad interpretativa y la evitación de la política como tal. Se describen aproximaciones a la práctica discursiva desde dentro de una de las recién formadas micronaciones, la cual, a su vez, provee una nueva manera de pensar el papel de la psicología en procesos sociales más amplios. Los siguientes principios alternativos para la práctica discursiva se derivan de esta descripción: dirigir la mirada de nuevo sobre la psicología y las fuerzas ideológicas que le dieron cabida; tratar las formas de representación como puntos para el ejercer el poder; analizar las formas sociales de manera situada contextual e históricamente; destacar formas de práctica discursiva que abren espacios para la argumentación acerca de la naturaleza de la interpretación y conectar las contradictorias fuerzas afectivas individuales con la lucha política.

This paper outlines problems with contemporary discourse analysis - a focus on everyday conversation, interpersonal interaction, formal sequences, correct explication and disciplinary segregation - problems which replicate general problems with the discipline of psychology (the gaze upon those outside its domain, reduction to the level of the individual, abstraction of behaviour and cognitive processes, claims to interpretative authority, and avoidance of politics as such). Approaches to discursive practice are described from within one of the recently-formed micro-nations which also provide a new way of thinking about the role of psychology in broader social processes. Alternative principles for discursive practice are derived from this description: turning the gaze back onto psychology and the ideological forces that give rise to it; treating forms of representation as sites for the relay of power; tracing how social forms are treated as contextually and historically situated; highlighting forms of discursive practice that open up spaces for interpretation and argument about the nature of interpretation; and connecting contradictory individual affective forces with the realm of political struggle.

Algunas de las especulaciones acerca de la relación entre tecnología y la naturaleza humana que se encuentran en los escritos de Ciencia Ficción del último medio siglo han pasado a formar parte del lenguaje y la cotidianidad de los sujetos post-industriales. Los futuros que se dibujan en los textos de Ciencia Ficción ayudan a entender en qué nos hemos convertido. Las nuevas formas de experiencia, las relaciones sociales y las formas de subjetividad que se hallan en la Ciencia Ficción pueden considerarse como recursos legítimos para el examen del presente. Y, en la medida que el pasado se reproduce a partir de nuevos sistemas dominantes de significados, lo que entendemos como realidad a partir de la tecnología y la naturaleza empieza a desaparecer. A menudo se llega a esta situación cuando no se sabe qué realidad es la correcta entre la miríada de realidades alternativas. Este artículo explora el modo en que el discurso psicoanalítico, tan enraizado en la cultura popular, encuentra en la psicología uno de sus máximos exponentes para fomentar subjetividades en armonía con la sociedad contemporánea.

Speculation around the role of technology and human nature are encountered in science fiction writing, and this writing provides discursive resources for post-industrial subjects. The kinds of futures that are outlined in science fiction help us to understand what kind of subjects some of us have become. New forms of experience, social relations and forms of subjectivity that we find in science fiction are resources examined in this paper, including the way the past is re-presented to us in myriad forms of alternative reality. This article explores the way in which psychoanalytic discourse, pervasive in popular culture, produces forms of subjectivity compatible with contemporary society.

The microdomains of Ca2+ in the cytosol around the mouth of open Ca2+ channels are the basic `building blocks' from which cellular Ca2+ signals are constructed. Moreover, the kinetics of local [Ca2+] closely reflect channel gating, so their measurement holds promise as an alternative to electrophysiological patch-clamp recording as a means to study single channel behavior. We have thus explored the development of optical techniques capable of imaging single-channel Ca2+ signals with good spatial and temporal resolution, and describe results obtained using total internal reflection fluorescence microscopy to monitor Ca2+ influx through single N-type channels expressed in Xenopus oocytes

O encontro intelectual entre três escritores simpáticos, em algum nível, ao trabalho de Lacan foi reunido no livro Contingência, Hegemonia, Universalidade (Butler, Laclau e Zizek, 2000a). Esses três autores são bem conhecidos em um conjunto difuso de campos que vão dos "estudos culturais" (cultural studies) à teoria literária e à teoria política. Como o subtítulo do livro indica - "Diálogos Contemporâneos da Esquerda" - eles também possuem alguma afinidade com o marxismo, "pós-marxismo" e política feminista. Uma questão que este debate entre três pensadores da teoria social lacaniana freqüentemente recoloca diz respeito à possibilidade de articular a teoria lacaniana com a política radical. No presente artigo discute-se se há implicações clínicas para esta leitura proposta pela esquerda Lacaniana, na qual os três autores estão engajados. Tomando como ponto de confluência o livro acima, o objetivo trabalho é mostrar como a prática política e a prática clínica encontram certos pontos de congruência em torno de temas como a negatividade, a sexualidade e a subversão do sujeito.

An intellectual encounter between three writers sympathetic to some degree with Lacan's work has been recorded in the book Contingency, Hegemony, Universality (Butler, Laclau and ·i·ek, 2000a). These three writers are well known in the overlapping collection of fuzzy sets "cultural studies", "literary theory" and "political theory", and, as the subtitle of the book "Contemporary Dialogues on the Left" indicates, they also have some sympathy with Marxist, "post-marxist" or feminist politics. One question that the debate between the three often returns to is whether it is possible to articulate Lacanian theory with radical politics. However, another question that is embedded in the encounter but which is only obliquely addressed is whether there are clinical implications for the kind of leftist readings of Lacan that these three writers engage in. I focus on that question in this paper.
