Vers une théorie antivitale, antihoméostatique et antiadaptative de la vie chez Freud: Le travail du concept de pulsion

Indexación: Scopus.Situado en el examen del concepto de pulsión [Trieb], piedra angular de la arquitectura teórica del psicoanálisis, el presente artículo pretende destacar dos grandes líneas de análisis: en primer lugar, mostrar el conjunto de los aspectos filosóficos y ontológicos que el concepto moviliza en su reflexión sobre los dinamismos y los sentidos de la vida humana; y, en segundo lugar, evidenciar la subversión que el concepto establece en el seno de los postulados mayores del pensamiento científico, filosófico y médico del siglo XIX, al introducir una concepción general de la vida como un acontecer esencialmente antivital, antihomeostático y antiadaptativo, en el cual las tendencias a la muerte, a la degradación y a la inercia forman parte de su patrimonio más arcaico e inmanente.Placé dans l’examen du concept de pulsion [Trieb], soubassement angulaire de l’architecture théorique de la psychanalyse, cet article prétend souligner deux grandes lignes d’analyse: premièrement, montrer l’ensemble des aspects philosophiques et ontologiques que le concept mobilise dans sa réflexion sur les dynamismes et les sens de la vie humaine ; et, deuxièmement, avérer la subversion que le concept établit au sein des postulats majeures de la pensée scientifique, philosophique et médicale du XIXe siècle, de la sorte d’y introduire une conception générale sur la vie en tant que avènement essentiellement antivital, antihoméostatique et antiadaptatif, dans lequel les tendances envers la mort, la dégradation et l’inertie font partie de son patrimoine le plus archaïque e immanentfile:///C:/Users/paula.pardo/Downloads/246-642-1-PB.pd

Fingering Instabilities on Reaction Fronts in the CO Oxidation Reaction on Pt(100)

Fingering instabilities arising from local perturbations to planar reaction fronts in the CO oxidation reaction on Pt(100) are presented. CO oxidation represents a heterogeneous nonlinear system with the necessary kinetic and diffusive transport properties to support the development of fingered wave fronts. External forcing was utilized to create CO wave fronts on an otherwise monostable, O-covered surface, which, upon destabilization, gave rise to fingers of adsorbed CO extending into the O adlayer ahead of the reaction front. Finger spreading and tip-splitting were observed as the finger pattern evolved towards an intrinsic wavelength, independent of the length of the reaction front, calculated to be approximately 40 μm. Our data also show the presence of a shielding process, where at wavelengths less than twice the observed intrinsic value, additional fingers were created on the reaction front through a tip-splitting bifurcation of an existing finger. At wavelengths greater than twice the intrinsic value, additional fingers formed in the troughs between adjacent fingers, apparently unaffected by the presence of the larger surrounding fingers

Panorama geopolítico del mundo actual. Medios de comunicación y cambios en la escena política: El ascenso de Podemos

El impacto de los nuevas formas y técnicas de comunicación política en las sociedades afectadas por la crisis ha provocado cambios en la escena política. En algunos países el ascenso de nuevos partidos políticos ha sido posible por sus aciertos al construir sus mensajes y objetivos, pero también por el apoyo de algunos medios de comunicación de masas y por el uso adecuado de las nuevas tecnologías. El caso de Podemos en España es un buen ejemplo de esta combinación de factores.The impact of new forms and techniques of political communication in societies affected by the crisis has caused changes in the political scene. In some countries the rise of new political parties has been made possible by their success in building their messages and objectives, but also by the support of some mass media and the proper use of new technologies.

Equilibrium States for Random Zooming Systems

In this work, we introduce the notion of random zooming systems and prove the existence of equilibrium states for which we call random zooming potentials, that include the hyperbolic ones, possibly with the presence of a critical set. The proof follows ideas of the work [4]. With a mild condition, we obtain uniqueness. We also prove that the classes of random zooming potentials and random hyperbolic potentials are equivalent and also contain the null potential, giving measures of maximal entropy

Interannual and interdecadal variability in the timing and strength of the spring transitions along the United States west coast

Past studies of the Oregon and Washington coast have shown a rapid change in the coastal ocean conditions with the onset of upwelling in spring. This process, called the spring transition marks the change from winter to summer conditions along the west coast of Unites States. To examine the interannual and interdecadal variability of the spring transition, a state-space statistical model is applied to records of adjusted sea level (ASL) and the Coastal Upwelling Index (CUI) for the years 1971- 1998. The same model is applied to the single Crescent City sea level from 1953 to 1998 to extend the analysis to the longest period possible. The state-space model estimates nonlinear, step-like changes in the first Empirical Orthogonal Function time series of these two variables along the northern California, Oregon and Washington coast. The spring transition dates are obtained using both variables between 1971-1998. In general the spring transition dates and strengths do not show a systematic change in the mid-1970's, when other changes have been noted in the North Pacific ocean and atmosphere. Although the dates after 1977 appear more variable. The spring transitions are consistently strong for the periods 1972-1975 and 1995-1998; during 1984-1994, the transitions are more often weak and variable. Using composite maps of sea level pressure (SLP) and wind stress for years with weak and strong transitions, we present characteristic fields of surface forcing, before, during and after the transition. We conclude that: before strong transitions, there is a strong Aleutian Low, centered in the middle of the Gulf of Alaska, inducing strong downwelling winds from ~40°-50° N; during the strong transitions there is a rapid expansion of the North Pacifica High and weakening and splitting of the Aleutian Low; after strong transitions the North Pacific High creates upwelling favorable winds from 50° N to Baja California. Before weak transitions the Aleutian low is centered northeastward, inducing weaker downwelling winds along the coast north of 40° N; the North Pacific High is relative weak and an extends to -40° N; during weak transition the North Pacific High expands northwestward to -45° N and the Aleutian Low remains strong; after weak transitions, downwelling-favorable winds continue north of 45° N
