Una teoría balance de la sabiduría
Robert J. Sternberg
Persona , 2012,
Abstract: Aun cuando resulta difícil defi nir la sabiduría, los psicólogos han desarrollado teorías acerca de este tema; una de ellas es la teoría del balance, que postula que a la hora de tomar decisiones, los individuos sabios se basan en sus valores y conocimientos, que balancean los intereses confl ictivos de naturaleza intrapersonal, interpersonal y extrapersonal, en plazos cortos y largos. Este modelo conceptual de la sabiduría está orientado a la acción y toma en cuenta los valores y conocimientos relevantes, sumados a la consideración de los múltiples intereses y a sus posibles consecuencias. Este modelo teórico, además, no solamente puede ser aprendido por los estudiantes, sino también ense ado por los profesores.
The Theory of Successful Intelligence
Robert J. Sternberg
Revista Interamericana de Psicología , 2005,
Abstract: Este artículo presenta una teoría de Inteligencia exitosa. La teoría es substancialmente más ancha que la teorías convencionalesde inteligencia. Define inteligencia por lo que se refiere a la habilidad de lograr las metas de uno en la via, dentro delcontexto sociocultural de uno. El artículo es dividido en cuatro partes. El artículo abre con una consideración de lanaturaleza de inteligencia. Entonces discute una medida de inteligencia. Luego discute cómo las personas pueden serinteligentes pero ingenuas. Finalmente, dibuja las conclusiones
There is No Place for Hostile Reviews
Robert J. Sternberg
International Journal of Clinical and Health Psychology , 2003,
Abstract: Los estudiantes de Tercer Ciclo en Psicología Científica reciben mucha información de cómo redactar artículos para publicar; sin embargo, no reciben información sobre cómo revisar los artículos de otros para su posterior publicación en revistas. Esto es un error. Muchas profesionales aportan críticas hostiles que a veces parecen ser más bien un ataque personal que una crítica constructiva del artículo en revisión. Este artículo plantea que las revisiones de tipo hostil no tienen lugar en este campo y no hacen más que socavar a la Psicología y sus respectivas profesiones.
心理科学进展 , 1987,
Abstract: 智力理论和检验这些理论研究主要是解决有关智力的三个基本问题:①智力与个体的内部世界的关系如何?②智力与个体的外部世界的关系如何?③智力与经验的关系如何?本文提出了作为各种理论的基础的心理模式,如:地理模式、生物学模式、社会学模式等,探讨了这些模式的优点和局限性。还提出了三种结构理论(triarchitictheory)把上述三个问题初步综合起来。

Presentation of Trypanosomiasis in Nkhotakota
J Chisi, A Nkhoma, J Sternberg
Malawi Medical Journal , 2007,
Abstract: In 2002, we identified 28 people in Nkhotakota District who were suffering from Human African Trypanosomiasis (HAT). Sixteen of these were identified when they presented to the District Hospital with a febrile illness. The remaining twelve were identified through a rural cross-sectional survey, in which 500 people were visited in their homes, persons found to be febrile, were examined by blood film microscopy. Of the 28 people, 50% (14) presented within a month of the onset of symptoms. Sixteen (57%) had splenomegaly, and 24 were anaemic ([Hb] <12 g/dl). Four patients died (14%), of which two were in the late stage of the disease. None of the patients recall having a chancre that could be attributed to the bite of tsetse flies. 9 out of 28 (32%) reported illness longer than 90 days. Of the 9 patients 6 (66%) of them remained in the early stage after reporting illness of 180 days. This study reports on the prevalence and clinical features of Trypansoma brucei rhodesiense infection in a endemic district in Malawi. Malawi Medical Journal Vol. 19 (4) 2007 pp. 140-141
Coordination of opposing sex-specific and core muscle groups regulates male tail posture during Caenorhabditis elegans male mating behavior
Allyson J Whittaker, Paul W Sternberg
BMC Biology , 2009, DOI: 10.1186/1741-7007-7-33
Abstract: Genetic and laser ablation analysis, in conjunction with behavioral assays were used to determine neurotransmitters, receptors, neurons and muscles required for the regulation of male tail posture. We showed that proper male tail posture is maintained by the coordinated activity of opposing muscle groups that curl the tail ventrally and dorsally. Specifically, acetylcholine regulates both ventral and dorsal curling of the male tail, partially through anthelmintic levamisole-sensitive, nicotinic receptor subunits. Male-specific muscles are required for acetylcholine-driven ventral curling of the male tail but dorsal curling requires the dorsal body wall muscles shared by males and hermaphrodites. Gamma-aminobutyric acid activity is required for both dorsal and ventral acetylcholine-induced curling of the male tail and an inhibitory gamma-aminobutyric acid receptor, UNC-49, prevents over-curling of the male tail during mating, suggesting that cross-inhibition of muscle groups helps maintain proper tail posture.Our results demonstrated that coordination of opposing sex-specific and core muscle groups, through the activity of multiple neurotransmitters, is required for regulation of male tail posture during mating. We have provided a simple model for regulation of male tail posture that provides a foundation for studies of how genes, molecular pathways, and neural circuits contribute to sensory regulation of this motor behavior.Animals have developed a wide variety of motor behaviors to adapt to their changing environments. Impressive progress has been made in understanding how neurons and neural circuits act to regulate motor behavior [1]. However, less is known about how genes and molecular pathways contribute to neural circuits to regulate motor behaviors [2]. To better understand this, we studied male mating in Caenorhabditis elegans. Arguably the most complex motor behavior displayed by this organism, male mating can be separated into at least six sub-steps: respon
Kollaboration von der Antike bis zum 21. Jahrhundert. Ein Diskussionsbeitrag
Ungern-Sternberg, Jürgen von
Studia Humaniora Tartuensia , 2004,
Abstract: 'Collaboration' got its negative meaning only in the special situation of the Vichy-Régime in front of the victorious German Reich. But it could be of some use to look for similar cases in earlier historical periods: the collaboration of many Greeks with the Persian Empire in the fifth century B.C. and with Rome in the second century B.C. Another one could be Caupo, chief of the Livonians, in the period of the occupation of the eastern region of the Baltic Sea by the Germans.
Bifurcation diagram and pattern formation in superconducting wires with electric currents
J. rubinstein,P. Sternberg,Q. Ma
Physics , 2007, DOI: 10.1103/PhysRevLett.99.167003
Abstract: We examine the behavior of a one-dimensional superconducting wire exposed to an applied electric current. We use the time-dependent Ginzburg-Landau model to describe the system and retain temperature and applied current as parameters. Through a combination of spectral analysis, asymptotics and canonical numerical computation, we divide this two-dimensional parameter space into a number of regions. In some of them only the normal state or a stationary state or an oscillatory state are stable, while in some of them two states are stable. One of the most interesting features of the analysis is the evident collision of real eigenvalues of the associated PT-symmetric linearization, leading as it does to the emergence of complex elements of the spectrum. In particular this provides an explanation to the emergence of a stable oscillatory state. We show that part of the bifurcation diagram and many of the emerging patterns are directly controlled by this spectrum, while other patterns arise due to nonlinear interaction of the leading eigenfunctions.
Phase transition curves for mesoscopic superconducting samples
H. T. Jadallah,J. Rubinstein,P. Sternberg
Physics , 1998, DOI: 10.1103/PhysRevLett.82.2935
Abstract: We compute the phase transition curves for mesoscopic superconductors. Special emphasis is given to the limiting shape of the curve when the magnetic flux is large. We derive an asymptotic formula for the ground state of the Schr\"odinger equation in the presence of large applied flux. The expansion is shown to be sensitive to the smoothness of the domain. The theoretical results are compared to recent experiments.
