Catalonia: Federalism or Secession?  [PDF]
Ramón Máiz, Nieves Lagares, María Pereira
Open Journal of Political Science (OJPS) , 2018, DOI: 10.4236/ojps.2018.84031
Abstract: Is there a political space for a possible federal accommodation of the demands of self-government in Catalonia and how is it configured? In order to answer these questions, we address first the conceptualization of federalism, and then, from an evolutionary perspective, we focus on the “Catalan issue” and its institutional outputs. The general assumption, in political and media discourse, namely, that “being in favour of the independence process”, “wanting to separate from Spain” and “being nationalist” constitute a single argument and mean exactly the same, has served to conceal a debate that is very complex, plural and full of nuances. We pose an analysis that pivots on the identity question and the type of political-territorial solution, the importance of the different leaderships in the process and the party identification with respect to the constructive nature of the political preferences of the electors and their positioning on the issues.
Caracterización morfológica de especies del género Passiflora de Colombia
Marín Tangarife Mónica María
Acta Agronómica , 2009,
Abstract: Se caracterizaron 21 especies de Passiflora las que incluyeron tres subgéneros, mediante 66 descriptores cuantitativos y 100 cualitativos. El análisis de componentes principales (ACP) de los descriptores cuantitativos identificó dos componentes con valor propio superior a 1, asociados con hoja y flor, los cuales explicaron 80% de la varianza total de las accesiones estudiadas. Con el análisis factorial de correspondencia múltiple (AFCM) de los descriptores cualitativos se identificaron tres dimensiones, que explicaron 82% de la varianza total; a la segunda se asociaron tipo de crecimiento, número de flores por nudo y color de la última serie de los filamentos en el ápice; a la tercera, forma y margen de la bráctea, margen de la bráctea; y a la primera las demás variables cualitativas. El análisis de agrupamiento (distancias de 'city-block-Manhattan') evidenció dos grandes grupos, según la longitud del hipantio -especies con flor de hipantio corto y largo-. El análisis de clasificación también mostró que la morfología floral fue determinante en la discriminación infragenérica en Passiflora.
La cobertura televisiva del fútbol en el Sur de Brasil y de Espa a: RBS – Canal Sur
Joaquín M. Marín Montín
Revista Latina de Comunicación Social , 2002,
Abstract: Este artículo constituye parte de un trabajo comparativo entre Brasil y Espa a, correspondiente al tratamiento que los medios de comunicación hacen del deporte. En él se analizan las claves que configuran el acercamiento a un mismo fenómeno sociológico, como es el fútbol, en dos realidades culturales diferentes. La programación deportiva de televisión llevada a cabo por Canal Sur en Andalucía y RBS en Rio Grande do Sul, así como la cobertura que ambas cadenas realizan en sus retransmisiones en directo del fútbol completan el análisis del presente estudio.ABSTRACTThis article is part of a comparative research between Brazil and Spain, about how the media treats the sports activities. Besides, this study analyses the keys of the same sociological phenomenon, which is football, in two different cultural realities. The broadcasting on television regarding sports events in Andalusia with Canal Sur, and Rio Grande do Sul with RBS. The live broadcasting of these channels completes the analysis of the present research.
A Comparative Study on the Structural and Vibrational Properties of Two Potential Antimicrobial and Anticancer Cyanopyridine Derivatives  [PDF]
María J. Márquez, María B. Márquez, Pablo G. Cataldo, Silvia A. Brandán
Open Journal of Synthesis Theory and Applications (OJSTA) , 2015, DOI: 10.4236/ojsta.2015.41001
Abstract: 2-Hydroxy-4,6-dimethylpyridine-3-carbonitrile and 2-chloro-4,6-dimethylpyridine-3-carbonitrile compounds have been studied from a theoretical point of view in order to know their structural and vibrational properties in gas and aqueous solution phases by means of Density Functional Theory (DFT) calculations. The stable structures in both media were optimized by using the hybrid B3LYP/6-31G* method and the solvent effects in aqueous solution were studied by using the integral equation formalism of the polarizable continuum model (IEFPCM) employing the selfconsistent reaction field (SCRF) method. Detailed vibrational analyses for both compounds in the two phases were performed combining the DFT calculations with Pulay’s Scaled Quantum Mechanics Force Field (SQMFF) methodology. The different interactions for both compounds were analyzed by means of the bond orders, atomic charges, solvation energies, dipole moments, molecular electrostatic potentials and force constants parameters. The nature of the interactions was studied by using different descriptors.
Opciones de cobertura para defectos en codo Coverage options for elbow defects
R. Graciano,M. Marín,M. Londinsky
Cirugía Plástica Ibero-Latinoamericana , 2012,
Abstract: La región del codo es un área anatómica de atención frecuente para el cirujano plástico, tanto en situaciones en las que una cicatriz limita la movilidad del miembro superior, como cuando un defecto de cobertura supone la exposición de elementos nobles. Los procedimientos a considerar para la cobertura de defectos de tejidos blandos en esta zona son los injertos, colgajos locales, regionales, libres y a distancia. Presentamos una serie de 9 casos clínicos intervenidos quirúrgicamente en el periodo comprendido entre enero del 2004 y mayo del 2006, con un seguimiento promedio de 2 a os. The elbow region is an anatomical area of frequent attention to the plastic surgeon, in situations where a scar may limits upper limb mobility, as when a defect of coverage involves exposing of noble elements. The procedures to be considered for coverage of soft tissue defects in this area are: grafts, local, regional, distant and free flaps. We present a series of 9 clinical cases operated on in the period between January 2004 and May 2006, with a mean follow up of 2 years.
Optimal Use of Conservation and Accessibility Filters in MicroRNA Target Prediction
Ray M. Marín, Ji?í Vaní?ek
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0032208
Abstract: It is generally accepted that filtering microRNA (miRNA) target predictions by conservation or by accessibility can reduce the false discovery rate. However, these two strategies are usually not exploited in a combined and flexible manner. Here, we introduce PACCMIT, a flexible method that filters miRNA binding sites by their conservation, accessibility, or both. The improvement in performance obtained with each of these three filters is demonstrated on the prediction of targets for both i) highly and ii) weakly conserved miRNAs, i.e., in two scenarios in which the miRNA-target interactions are subjected to different evolutionary pressures. We show that in the first scenario conservation is a better filter than accessibility (as both sensitivity and precision are higher among the top predictions) and that the combined filter improves performance of PACCMIT even further. In the second scenario, on the other hand, the accessibility filter performs better than both the conservation and combined filters, suggesting that the site conservation is not equally effective in rejecting false positive predictions for all miRNAs. Regarding the quality of the ranking criterion proposed by Robins and Press and used in PACCMIT, it is shown that top ranking interactions correspond to more downregulated proteins than do the lower ranking interactions. Comparison with several other target prediction algorithms shows that the ranking of predictions provided by PACCMIT is at least as good as the ranking generated by other conservation-based methods and considerably better than the energy-based ranking used in other accessibility-based methods.
Pérez Marín,Mónica;
Investigación y Desarrollo , 2012,
Abstract: this paper attempts to identify and characterize, from a histórica!perspective, "the environmenta! discourses" that have been createdand have circulated on what we now know as national parks in colombia, specifically on the pnn katios national park. the research argues that such discourses have been constructed, propagated, institutionalized and legitimized as a means and dynamic factor in a broader discourse we have called "development discourse."

Badia Martín,M. del Mar;
Estudios pedagógicos (Valdivia) , 2003, DOI: 10.4067/S0718-07052003000100006
Abstract: this article analyzes body punishment, distinguished from that of physical abuse. an analysis on the issue in different countries is made in relation to the application of ways of punishment. the investigation shows that certain societies still(yet) use corporal punishment as one more form(way) to stop troublesome behaviors. this can lead us to thinking that it is not necessary to abandon the thesis that this strategy is rejected at present by all the sectors of the society, but we must be sensitive to the idea that certain professionals and families consider it as one instrument for the alteration of unacceptable behaviors.
La población del corregimiento de Carangas (virreinato del Río de la Plata) a fines del siglo XVIII
Gavira Márquez, María Concepción;
América Latina en la historia económica , 2010,
Abstract: this article analyzes the characteristics of the population of carangas (end 18th century): its activities and its tributary obligations. for an evaluation and demographic quantification we have used fiscal sources, which cover most of this high andean district (partido or corregimiento). the analysis of the information of these fiscal censuses, together with other sources which show economic activities, will allow us to perceive the strategies of the tributaries when confronted with the impoverishment that overtook the corregimiento at this time. the analysis of the tributary amounts and the increase in the category of forasteros ("outsiders") leads us to conclude that, in the face of their economic dificulties, the population sought strategies within the established fiscal system to reduce their real rates of tribute.
