Bidirectional trans‐synaptic signaling is essential for the formation, maturation, and plasticity of synaptic connections. Synaptic cell adhesion molecules (CAMs) are prime drivers in shaping the identities of trans‐synaptic signaling pathways. A series of recent studies provide evidence that diverse presynaptic cell adhesion proteins dictate the regulation of specific synaptic properties in postsynaptic neurons. Focusing on mammalian synaptic CAMs, this article outlines several exemplary cases supporting this notion and highlights how these trans‐synaptic signaling pathways collectively contribute to the specificity and diversity (...) of neural circuit architecture.

El siguiente ensayo rastrea las reflexiones de Friedrich Hölderlin en torno a lo mítico. El argumento, expuesto una y otra vez en su correspondencia, sus ensayos y poemas, continuamente refinado y corregido, es que, expresado en lenguaje poético, el mito permite recuperar una visión del mundo fragmentada con el ímpetu analítico finisecular. El concepto de lo mítico de Hölderlin no solo está profundamente influido por el contexto histórico e intelectual en los lindes del Frühromantik, la filosofía de Fichte, la estética (...) de Schiller y la Revoluciónfrancesa como notas principales, sino también por las experiencias de la niñez, las lecturas de los colegios conventuales o los encuentros en Tubinga o Fráncfort. Finalmente, el texto muestra cómo estas indagaciones cristalizan en distintos motivos de su producción lírica. (shrink)

En el artículo se describe el tránsito filosófico-existencial de Tula, protagonista de la novela La tía Tula de Miguel de Unamuno, por los tres estadios vitales del filósofo danés Søren Kierkegaard. A lo largo del texto, se muestra que las dudas existenciales que se plantea la protagonista son extensivas para todo el género humano. Además, el texto busca mostrar cómo la narrativa del pensador español está plagada de reflexiones filosóficas y está fuertemente influida por el existencialismo cristiano de Kierkegaard. Debatiéndose (...) entre la fe y la razón, Tula transita por los estadios tomando decisiones que entrañan sufrimiento. En esta novela, se plasman los afanes del ser humano por la perpetuación, inmortalidad y salvación frente al rostro descarnado de la nada. (shrink)

The use of images in education has received little attention despite the dual role of images in school textbooks, one aimed at the acquisition of knowledge and the other at the transmission of attitudes, values and norms, that constitute a valuable source of historical, educational and communicative research. We will study, through the analysis of content, the characteristics of the catechisms, the legislation of the time related to the publication of school textbooks, the presence of images, types, the didactic function (...) and the transmission of social models and ideology. The research suggests that the images of school catechisms are not simply reflections of a reality that facilitates the learning of the contents taught in schools, but that they also become an effective tool in the transformation of the values and ideological thinking of the social context in which they are produced.

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

This paper proposes and analyzes the psychometric properties of the PREVI-A scale. It describes the process of item development, the factorial structure of the scale, reliability, evidence of validity and diagnostic performance with regard to recidivism risk in juvenile offenders. The sample was made up of 212 juvenile offenders held at detention centers run by the Madrid Agency for Reeducation and Reintegration of Juvenile Offenders, a regional government body. Statistical analyses were used to corroborate the theoretical factorial structure of the (...) PREVI-A, which consists of six risk/protection dimensions based on the Risk-Needs-Responsivity Model, and to obtain empirical support for the reliability and validity of PREVI-A as a tool to assess the risk of recidivism by juvenile offenders in Spain.

This article examines the Kantian ideas on motion in his work Metaphysical Foundations of Natural Science. In that essay, Kant holds that motion as a concept—from its connotation as elemental and fundamental predicament of the material reality—mobilises in matter all the characteristics of its essence as a property. Nevertheless conceiving motion as a concept does not enable us to confirm the existence of motion itself in the natural world because ‘the possibility of specific natural things can’t be discovered from their (...) mere concepts.’. Therefore, the concept of movement does not evidence the existence of the movement or its characteristics and properties. Such claim would imply that motion as a concept is not evidence of the existence of motion as such and, therefore, the properties of matter cannot be mobilised based on that concept because they are characteristics of the essence of motion. Then, how does Kant intend to denote motion? Why pretend to explain matter form the concept of motion if a pure concept is, by definition, independent of the data obtained from the sensibility?. Therefore, we will demonstrate that such weakness is the breaking point of the Kantian concept of motion in his “dynamic-metaphysical” model. (shrink)

ABSTRACT Modernity conceived prison as a primary vehicle for the humanization of criminal punishment. Contrarily to this theoretical and normative model, the practice of imprisonment has conserved several elements of the physical and psychological affliction typical of pre-modern forms of criminal retribution. Prison actually embodies a major theme of dystopian fiction because of the useless suffering it somehow implies. Nonetheless, the concrete dystopian experience of incarceration has frequently been challenged by the utopian horizons of opera, which Charles Fourier once conceived (...) as a passionate pivot for social change. From Fidelio to The Shawshank Redemption, opera has represented a utopian wonder of voices that soar “higher and farther than anybody in a grey place dares to dream.” Surrounded by the walls of prison, opera is not merely a snobbish artistry: it may constitute a real pre-text for the rights and dignity even infamous men and women deserve.

This article traces commonalities between the practices of visual animation and modern law through a political and jurisprudential reading of the animated film Ratatouille. It contends that Ratatouille’s treatment of the ontological and anthropological problem of the human soul not only addresses the philosophical complexities inherent to animation, but also the ideological and material conditions that currently govern the practice of égaliberté in contemporary liberal democracies.

Hablar de conflictos y negociación en medio de la guerra no es fácil. Los ánimos exacerbados nunca han sido buenos consejeros para la toma prudente de decisiones, de allí que el ejercicio por tratar de entender estos temas es de la mayor importancia en momentos de incertidumbre como los que vivimos actualmente los colombianos.

Resulting that the instrument adapted to the Peruvian version is adequate according to statistics such as Cronbach's Alpha. Concluding that the digital competences improved the academic quality and have (...) a good level. Society is waiting for the next step to know what is presented to us in education. (shrink)

This article is a first attempt to line out the conditions under which executives might have a real self-interest in pursuing a broad stakeholder management (SM) orientation to enlarge their power. We suggest that managers have wider latitude of action under an SM approach, even when this is instrumental to financial performance. The causally ambiguity of the performance effects of idiosyncratic relationships with stakeholders not only makes SM strategy difficult for competitors to imitate but also increases managerial discretion. When managers (...) use this situation for their own benefit, they can undermine the purported goals of the SM approach. By analyzing some of the factors that might lead to such disfunctionalities, this article advances a theory of the potential dark side of SM. (shrink)
