Matar al padre: un modelo de reconstrucción del conflicto social desde la Sociología de las Organizaciones

El presente articulo analiza sociológicamente la forma en que las personas que forman parte de una organización compleja reconstruyen un conflicto social interno. Ese proceso se interpreta desde la teoria freudiana del proceso de "matar al padre". Se utiliza la elaboración teórica en Totem y tabú de 1912. La segunda aplicación es a la teoria de las desorganizaciones, dentro de la Sociologia de las Organizaciones. En el análisis se utilizan transcripciones de entrevistas en grupo (10 EEP) realizadas durante un año (1993) dentro de la organización (la policia municipal de una gran ciudad española), asi como información de observación participante (OP) durante un año. El articulo analiza primero los grupos que existen dentro de la estructura actual de la organización y el tipo de conflictos que generan entre ellos. En la parte central se estudia el poder a traves de los sistemas de jerarquización, el poder de jefatura, los mandos intermedios y lo que Perrow conceptualiza como el poder de los sin poder. Se interpreta la experiencia pasada de derrocamiento del jefe como un caso de "matar al padre", analizando el conflicto actual como continuación del mismo proceso. Al no institucionalizarse el conflicto (sustituir la acción por la idea) se repite de forma simbólica el parricidio del jefe. El articulo muestra la forma en que la teoria psicoanalítica grupal se puede aplicar a las organizaciones complejas contemporáneas, permitiendo una interpretación sociológica para analizar la forma en que las personas construyen la realidad social. Muestra también la utilidad de la teoria de las desorganizaciones para el análisis de este tipo de organizaciones.This article analizes from a sociological point of view the way members of a complex organization reconstruct an internal social conflict. This process in interpreted, from a Freudian perspective, as a form of "Killing the father

Huellas del joven Martínez Ruiz en el Azorín adulto: sobre el sistema ecléctico de la tetralogía crítica (1912-1915)

En este artículo se salvará la aparente distancia que separa al joven José Martínez Ruiz (1873-1967), simpatizante del anarquismo, del Azorín conservador en que se convirtió en su madurez. Para ello se presentará su tetralogía crítica, formada por Lecturas españolas (1912), Clásicos y modernos (1913), Los valores literarios (1914) y Al margen de los clásicos (1915), como el resultado de un anhelo juvenil por construir una historia de la literatura española. Se realizará un cotejo entre estas cuatro obras y el libro La evolución de la crítica, de 1899, con el objetivo de determinar qué influencia tuvieron las diversas escuelas teóricas examinadas en este opúsculo en su crítica literaria de madurez. De este análisis se concluirá que es posible apreciar una continuidad entre las metodologías críticas analizadas en La evolución de la crítica y las practicadas por el Azorín adulto. Asimismo, se propondrá que su labor crítica de madurez se sostiene sobre un sistema amplio y ecléctico heredado de estas teorías con las que se familiarizó en su juventud.This article expects to overcome the apparent distance noticed between the young José Martínez Ruiz (1873-1967), sympathizer of the anarchism, to the conservative author that later became known as Azorín. This way, his critical tetralogy (formed by Lecturas españolas, 1912, Clásicos y modernos, 1913, Los valores literarios, 1914, and Al margen de los clásicos, 1915) will be presented as a result of a young desire of writing a history of the Spanish literature. After this, the influence of his 1899 work La evolución de la crítica in the books mentioned above will be analyzed. In addition, it will be concluded that it is possible to appreciate continuity between the critical methodologies that Martínez Ruiz analyzed in La evolución de la crítica and those which he displayed to write his critical tetralogy. Finally, it will be proposed that his adult critical methodology is based on an eclectic system, which derives from the different theories of literary criticism that he learnt as a young writer

An unexpected actor in ammonium assimilation in conifer trees

Conifers are tree species with enormous environmental and economic interests but with several characteristics that complicate their investigation (big size, secondary compounds, large long-life cycles, megagenomes…). However, they are well adapted to ammonium-rich soils being a good model to study ammonium assimilation in plants. Although they have a special feature, only two glutamine synthetase (GS, EC 6.3.1.2) genes, GS1a and GS1b, coding for cytosolic proteins, have been identified. In angiosperms and in the gymnosperm Ginkgo biloba there are two types of this enzyme responsible of the ammonium assimilation: GS1 expressed in the cytosol and GS2 in the plastids. Until the date, the searches of new GS1 and GS2 genes in conifers have been made with classical biochemical and molecular biology techniques without satisfactory results. In the present context, the emergence of the next generation sequencing (NGS) techniques has open new opportunities in the resolution of old problems. They have allowed the whole sequencing of the massive conifer genomes and the analysis of their transcriptomes. Thus, in the framework of the European project ProCoGen, a gene expression atlas of the tissues of one-month seedlings was carried out using laser capture microdissection (LCM) and massive sequencing in maritime pine (Pinus pinaster), which is a conifer tree from the Southwestern Mediterranean region1. From the analysis of this work, a new gene coding for a new putative cytosolic GS has been identified, PpGS1c. 1Cañas, RA et al. (2017). Plant J, 91. 1064-1087Universidad de Málaga.

Design of a WSN for the sampling of environmental variability in complex terrain

Las mediciones de parámetros ambientales in situ utilizando sistemas de sensores conectados a una red inalámbrica se han generalizado, pero el problema de monitorear áreas grandes y montañosas por medio de una red de sensores inalámbricos (WSN) no está bien resuelto. Las principales razones de esto son: (1) la distribución de la variabilidad ambiental es desconocida en el campo; (2) sin este conocimiento, sería necesario un gran número de sensores para asegurar la cobertura completa de la variabilidad ambiental y (3) los requisitos de diseño de WSN, por ejemplo, la conectividad efectiva (intervisibilidad), las distancias límite y la redundancia controlada por prueba y error. Utilizando la temperatura como variable ambiental objetivo, proponemos: (1) un método para determinar las clases ambientales homogéneas a muestrear utilizando el modelo de elevación digital (DEM) y simulaciones geométricas y (2) un procedimiento para determinar un diseño eficaz de WSN en complejos Terreno en términos de número de sensores, redundancia, coste y distribución espacial. La metodología propuesta, basada en sistemas de información geográfica y programación de números enteros binarios, se puede adaptar fácilmente a una amplia gama de aplicaciones que requieren un monitoreo ambiental exhaustivo y continuo con alta resolución espacial. Los resultados muestran que el diseño WSN es perfectamente adecuado para la topografía y las especificaciones técnicas de los sensores, y proporciona una cobertura completa de la variabilidad ambiental en términos de exposición al sol. Sin embargo, estos resultados aún deben ser validados en el campo y el procedimiento propuesto debe ser refinado.In-situ environmental parameter measurements using sensor systems connected to a wireless network have become widespread, but the problem of monitoring large and mountainous areas by means of a wireless sensor network (WSN) is not well resolved. The main reasons for this are: (1) the environmental variability distribution is unknown in the field; (2) without this knowledge, a huge number of sensors would be necessary to ensure the complete coverage of the environmental variability and (3) WSN design requirements, for example, effective connectivity (intervisibility), limiting distances and controlled redundancy, are usually solved by trial and error. Using temperature as the target environmental variable, we propose: (1) a method to determine the homogeneous environmental classes to be sampled using the digital elevation model (DEM) and geometric simulations and (2) a procedure to determine an effective WSN design in complex terrain in terms of the number of sensors, redundancy, cost and spatial distribution. The proposed methodology, based on geographic information systems and binary integer programming can be easily adapted to a wide range of applications that need exhaustive and continuous environmental monitoring with high spatial resolution. The results show that the WSN design is perfectly suited to the topography and the technical specifications of the sensors, and provides a complete coverage of the environmental variability in terms of Sun exposure. However these results still need be validated in the field and the proposed procedure must be refined.peerReviewe

The Barcelona Catania Paris Madrid energy density functional

The foundation and applications of the Barcelona Catania Paris Madrid (BCPM) energy density functional are briefly reviewed. BCPM uses a paradigm more rooted on density functional theory and fits most of its parameters to sophisticated microscopic nuclear matter calculations. Finite nuclei are accounted for by introducing a direct finite range surface term, spin orbit potential, Coulomb interaction and pairing. Applications of this functional to the calculation of finite nuclei properties are presented as well as applications to the description of neutron star physics. The large number of applications discussed are possible because of the local character of the functional that simplifies enormously calculations in finite nucleiOne of the authors (X.V.) acknowledges the partial support from Grants No. PID2020-118758GB-I00 and No. CEX2019-000918-M (through the “Unit of Excellence María de Maeztu 2020-2023” award to ICCUB) from the Spanish MCIN/AEI (DOI 10.13039/501100011033).

Bosonization on a lattice: The emergence of the higher harmonics

6 págs.; 2 figs.A general and transparent procedure to bosonize fermions placed on a lattice is presented. Harmonics higher than kF in the one-particle Green function are shown to appear due to the compact character of real electron bands. Quantitative estimations of the role of higher harmonics are made possible by this bosonization technique. © 1995 The American Physical Society.J.F. was supported by DEYCIT Project No. PB93-1248.Peer Reviewe

Coevolution of dynamical states and interactions in dynamic networks

We explore the coupled dynamics of the internal states of a set of interacting elements and the network of interactions among them. Interactions are modeled by a spatial game and the network of interaction links evolves adapting to the outcome of the game. As an example we consider a model of cooperation, where the adaptation is shown to facilitate the formation of a hierarchical interaction network that sustains a highly cooperative stationary state. The resulting network has the characteristics of a small world network when a mechanism of local neighbor selection is introduced in the adaptive network dynamics. The highly connected nodes in the hierarchical structure of the network play a leading role in the stability of the network. Perturbations acting on the state of these special nodes trigger global avalanches leading to complete network reorganization.Comment: 4 pages, 5 figures, for related material visit http:www.imedea.uib.es/physdept

Scission configuration in self-consistent calculations with neck constraints

The calculations of the potential-energy surface are essential in the theoretical description of the fission process. In the constrained self-consistent approach, the smooth evolution of nuclear shape is described from the ground state until a very elongated one with a narrow neck. In all microscopic calculations, the rupture of the neck at scission is associated with a substantial change of nuclear matter density distribution and rapid energy decrease. In this paper, we show that there is no discontinuity of the potential-energy surface at scission when multiconstrained calculations are applied with the neck constraint. An early rupture of the neck at lower quadrupole and octupole moments is discussed as competitive with the conventional fission path. We discuss the neck properties in the scission configuration. We find that the neck radius in the asymmetric fission mode cannot decrease below 2 fm, and the nuclear matter density cannot decrease below the saturation density. In the compact fission mode, nuclear density may go down to half of the saturation density before the rupture of the nec
