Method e historicity. The influence of Dilthey and medieval studies in the young Heidegger

El presente trabajo pretende analizar un segmento de particular interés en el pensamiento heideggeriano: se trata por un lado de la recepción de Dilthey y, por el otro, de los cursos que el joven profesor imparte, entre 1921 y 1922 sobre las cartas paulinas y sobre San Agustín y el neoplatonismo. En estos textos, podemos asistir a la decisiva introducción que Heidegger hace del historicismo en la fenomenología, y ver cómo esta aportación es fundamental a la hora de imprimir la personal huella de Heidegger a la fenomenología husserliana, para insistir en la historicidad de experiencias fundamentales y dar lugar a lo que se denominará giro hermenéutico.This paper will discuss a segment of particular interest in the Heidegger’s work, concerning, on the one hand, to the Dilthey’s reception and, on the other, to the courses that the young professor imparts between 1921 and 1922 about the Pauline epistles and Augustine of Hippo and the Neoplatonism. In these texts, we assist to the decisive influence that Heidegger makes of the historicism in the phenomenology and to see how his contribution is fundamental when he print his personal trace to the Husserl’s phenomenology to insist in the historicity of fundamental experiences and to give place to the hermeneutic turn

El Taller de Pintura, Una experiencia compartida

En este artículo se presentan algunos fundamentos, estrategias y resultados de las experiencias realizadas en el taller, llevadas a cabo durante el año 2013 en la cátedra de Pintura III, comisión “B”, de la Escuela de Bellas Artes de la Universidad Nacional de Rosario. Se plantearon como objetivos la adquisición de competencias, la experimentación y la formación en las problemáticas de la pintura contemporánea desde la teoría y, fundamentalmente, desde la práctica. Este campo disciplinar se encuentra en una permanente redefinición de sus prácticas artísticas, relacionadas con la expansión de los límites artísticos interdisciplinares. El arte en la actualidad posibilita múltiples caminos de investigación.Juda, Claudia. Universidad Nacional de Rosario. Facultad de Humanidades y Artes.

The welfare costs of self-fulfilling bank runs

We study the welfare implications of self-fulfilling bank runs and liquidity require- ments, in a neoclassical growth model where banks, facing long-lasting possible runs, can choose in any period a run-proof asset portfolio. In this framework, runs distort banks’ insurance provision against idiosyncratic liquidity shocks, and liquidity requirements resolve this distortion by forcing a credit tightening. Quantitatively, the welfare costs of self-fulfilling bank runs are equivalent to a constant consumption loss of up to 2.5 percent of U.S. GDP. Depending on fundamentals, liquidity requirements might generate small welfare gains, but also increase the welfare costs by up to 1.8 percent.info:eu-repo/semantics/publishedVersio

Micronarratives as the form of contemporary communication

Narratives can be considered as a way for presenting and representing reality, going beyond time, space, aesthetic form, and medium of conveyance. From Aristotelian classical principles, to structuralist rules, to post-structuralist plurality, the aesthetics of narrative representation is constantly put into discussion. Narratives are composed by both constant structures and figures, which determines whether an object can be identified as a narrative, and variables which determine the way in which it is conveyed on different media. In this paper, we concentrate on contemporary narratives on social media. After declaring what are the main characteristics of the medium in terms of affordances, content, and role of the users, we analyse two existing case studies using the concepts of remediation and narrativity. The paper aims at bringing a contribution to the discussion about contemporary aesthetics in media design, considering narratives as a matter of design, and investigating on the role of the designer

The emerging population of pulsar wind nebulae in hard X-rays

The hard X-ray synchrotron emission from pulsar wind nebulae (PWNe) probes energetic particles, closely related to the pulsar injection power at the present time. INTEGRAL has disclosed the yet poorly known population of hard X-ray pulsar/PWN systems. We summarize the properties of the class, with emphasys on the first hard X-ray bow-shock (CTB 80 powered by PSR B1951+32), and highlight some prospects for the study of Pulsar Wind Nebulae with the Simbol-X mission.Comment: Proceedings of the 2nd Simbol-X Symposium, AIP Conf.
