Recomposición de las sociedades rurales en zonas de conflicto armado: el caso de la cuenca del río Caguán
López Báez Camilo
Revista Colombiana de Sociología , 2007,
Abstract: En este trabajo se reflexiona, desde un enfoque multicausal, sobre algunos de los cambios que han experimentado las sociedades locales que se encuentran ubicadas en la cuenca del río Caguán, en el departamento del Caquetá. Se trata de identificar las variables centrales asociadas al conflicto armado que vienen incidiendo en la transformación de las comunidades rurales y en el comportamiento de sus principales tendencias en la perspectiva socioespacial. En la primera parte se describen las lógicas sobre las cuales se desarrolla el proceso de colonización primario de la zona durante el siglo XX, contrastando las particularidades de dos espacios: el Alto Caguán y, el Medio y Bajo Caguán. En la segunda parte, se analiza la incidencia territorial de la llegada y la consolidación de las Fuerzas Armadas Revolucionarias de Colombia (FARC), en cuanto a algunos de sus afectaciones en la expansión de la frontera agrícola. Después el estudio centra su atención en la generalización de los cultivos de uso ilícito, siembra de coca y su transformación en pasta base, y los diversos impactos que estas actividades generan en las comunidades rurales. Por último, se precisan algunos de los efectos sociales y espaciales que se derivan de la aplicación de ciertas políticas públicas, en particular de las relacionadas con el denominado desarrollo alternativo, la política de lucha contra las drogas y el "Plan Patriota". La ponencia finaliza con el comentario de algunas conclusiones provisionales derivadas del análisis, orientadas hacia futuras investigaciones para las sociedades rurales.

Prolonged coexistent central diabetes insipidus and cerebral salt wasting syndrome following neurosurgery  [PDF]
D. López de Lara, B. Joyanes, A. Llaneza, O. Pérez, B. Llorente, I. Runkle
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.32014
Abstract:

The coexistence of different water homeostasis abnormalities following neurosurgery represents a diagnostic and therapeutic challenge for intensive care units. This paper reports the case of a 13 year-old boy who underwent surgery for a suprasellar tumour and, immediately after surgery, developed a cerebral abscess, persistent diabetes insipidus (DI) as well as cerebral salt wasting syndrome (CSWS). The early onset of CSWS following DI has been associated with a poor prognosis and increased mortality. In cases in which these abnormalities coexist, the increased polyuria secondary to the rise in natriuresis associated with CSWS might be erroneously interpreted as a sign of poor control of the DI, thereby leading to therapeutic mistakes. Treatment basically consists of restoring electrolytes and the joint administration of desmopressin and fludrocortisone.

A Fixed Point Theorem for Mappings Satisfying a Contractive Condition of Rational Type on a Partially Ordered Metric Space
J. Harjani,B. López,K. Sadarangani
Abstract and Applied Analysis , 2010, DOI: 10.1155/2010/190701
Abstract: The purpose of this paper is to present a fixed point theorem using a contractive condition of rational type in the context of partially ordered metric spaces. 1. Introduction In [1], Jaggi proved the following fixed point theorem. Theorem 1.1. Let be a continuous selfmap defined on a complete metric space . Suppose that satisfies the following contractive condition: for all , , and for some with , then has a unique fixed point in . The aim of this paper is to give a version of Theorem 1.1 in partially ordered metric spaces. Existence of fixed point in partially ordered sets has been considered recently in [2–15]. Tarski's theorem is used in [7] to show the existence of solutions for fuzzy equations and in [9] to prove existence theorems for fuzzy differential equations. In [5, 6, 8, 11, 14], some applications to matrix equations and to ordinary differential equations are presented. In [3, 6, 16], it is proved that some fixed theorems for a mixed monotone mapping in a metric space endowed with a partial order and the authors apply their results to problems of existence and uniqueness of solutions for some boundary value problems. In the context of partially ordered metric spaces, the usual contractive condition is weakened but at the expense that the operator is monotone. The main idea in [8, 14] involves combining the ideas in the contraction principle with those in the monotone iterative technique [16]. 2. Main Result Definition 2.1. Let be a partially ordered set and . We say that is a nondecreasing mapping if for , . In the sequel, we prove the following theorem which is a version of Theorem 1.1 in the context of partially ordered metric spaces. Theorem 2.2. Let be a partially ordered set and suppose that there exists a metric in such that is a complete metric space. Let be a continuous and nondecreasing mapping such that with . If there exists with , then has a fixed point. Proof. If , then the proof is finished. Suppose that . Since is a nondecreasing mapping, we obtain by induction that Put . If there exists such that , then from , is a fixed point and the proof is finished. Suppose that for . Then, from (2.1) and as the elements and are comparable, we get, for , The last inequality gives us Again, using induction Put . Moreover, by the triangular inequality, we have, for , and this proves that as . So, is a Cauchy sequence and, since is a complete metric space, there exists such that . Further, the continuity of implies and this proves that is a fixed point. This finishes the proof. In what follows, we prove that Theorem 2.2 is still valid for ,
Historia de la Nutrición en la Argentina: nacimiento, esplendor y ocaso del Instituto Nacional de la Nutrición
López,Laura B; Poy,Susana;
Diaeta , 2012,
Abstract: this paper is intended to review the history of the national institute of nutrition, an institution that marked the initial course of nutritional science in argentina, which was founded by dr pedro escudero, mentor of the science of nutrition in argentina, also creator of the school of dietetics, the department of clinical nutrition and the dietitians doctors advanced course. in 1928 he started his activities in a wing of rawson hospital, the municipal institute of metabolic diseases, which was subsequently transferred to the national sphere, becoming the national institute of nutrition. it was the first latin american institute dedicated to the study of nutrition-related activities, and healthcare, teaching, research and advisory activities were developed there, with an integrative approach to biological, psychological and socio-cultural aspects in connection with food-nutritional issues. as part of the educational activities of the institute, in 1938 emerged the first graduates of the national school of dietitians, which was a pioneer in the training of dietitians in latin america. in 1947 dr pedro escudero leaves his position as director of the national institute of nutrition, intervened by the government in 1955. since that moment, the scientific production decreased significantly and in 1969 it was closed by the ministry of public health, on which it depended. in 2005 there was an archeological rescue of objects found during the excavations that were being carried out in a neighboring construction, where the center for mental health arturo ameghino currently operates. in the school of nutrition of the university of buenos aires there is an exhibit of photographs, objects and original publications depicting the history of the national institute of nutrition.
Efectos Individuales del Despido y la Resiliencia como Facilitador en la Búsqueda de Empleo
Sergio Andrés López B.
Panorama Socioeconómico , 2007,
Abstract: El objetivo de este artículo fue analizar los efectos individuales que produce el despido en el individuo y proponer una estrategia de resiliencia para enfrentar este proceso. Para ello se realizó una revisión de la literatura especializada de los efectos psicológicos más frecuentes provocados por el despido, entre los que destacan el aumento de los síntomas de stress, los sentimientos de inseguridad y de fracaso, la pérdida de autoestima y el deterioro de las relaciones familiares y sociales. Posteriormente, se realizó un análisis de la resiliencia como un factor de importancia para reducir el impacto de este proceso en el individuo y generar una experiencia de cambio personal. Las principales conclusiones de este estudio se alan que la resiliencia es una alternativa para reafirmar la propia identidad del sujeto, y como resultado de esto, facilitar la inserción en el mundo social y laboral.

ACTION-RESEARCH WITH THE LATIN KING ASSOCIATION IN MADRID: ON THE POSSIBILITIES AND LIMITS OF AN ALTERNATIVE STRATEGY WITH CONFLICTIVE YOUTH GROUPS
Bárbara Scandroglio,Jorge S. López
AIBR : Revista de Antropología Iberoamericana , 2010,
Abstract: This work presents a long term participatory action research conducted among the group of Latin Kings in Madrid, Spain. The project started up from a demand of the group itself, andbegan with a participatory analysis of the group status and needs. The researchers agreed with the members to perform a set of actions oriented to reinforce the positive aspects of the group dynamics, to develop resources for social reinsertion and support, to reduce the violent behavior, to connect the group with institutional and social networks and to advance in the social recognition of the group as a legitimized social actor. The project focused particularly tothe actions performed on the meeting spaces of the group, as well as its communication channels. These actions included several strategies on the individual, group, community and socio-institutional level. During the process, the group adopted pro-social norms on itsdiscourses and dynamics. It also developed strategies of self restriction to affront of potentialconflicts and became a positive social actor. However it was not achieved the political and institutional support, needed for an open development without the police intervention. This aspect made it difficult to obtain resources to consolidated objectives and to reinforce social efforts in the members of the association.
