Aborto en Uruguay y América Latina: el posicionamiento de los ciudadanos
Authors: Rossi Máximo , Triunfo Patricia 
Published: November 2015

<p>En la mayoría de los países de América Latina, el aborto es ilegal, aunque existen causas atenuantes y eximentes de su práctica. Sin embargo, estudios realizados en países con procesos liberalizadores por más de dos décadas, como Estados Unidos, muestran la persistencia de actitudes diferentes frente al aborto, que van desde visiones pro vida a visiones pro elección. Este trabajo, a partir del Latinobarómetro 2007, analiza los patrones actitudinales de los individuos ante el aborto, con énfasis en su grado de justificación en función de características socioeconómicas, fe religiosidad, así como en las características propias de los países. Las estimaciones por mínimos cuadrados ordinarios para 18 países de América Latina muestran que los hombres menores de 40 años, agnósticos, con alto nivel educativo y acceso socioeconómico son quienes más justifican el aborto; así mismo, Uruguay —en especial, su población femenina— es el país donde más se justifica.</p>

Los contratos internacionales en el marco de los negocios de las mipymes
Authors: López Fonseca Martha Cecilia 
Published: November 2015

<p>El objetivo es explicar de manera general algunas de las posibilidades que tienen las micro, pequeñas y medianas empresas (mipymes) para internacionalizarse, teniendo en cuenta, entre otros aspectos, la elaboración del contrato preferiblemente escrito. El significado del comercio internacional parte de las corrientes mercantilistas, clásica y neoclásica, y de postulados contemporáneos como la teoría de la ventaja competitiva, que demuestran la importancia del intercambio de bienes y servicios para las economías. Las relaciones comerciales internacionales de cualquier empresa se basan en requerimientos de importar o exportar materias primas, maquinaria, bienes finales e intermedios, o aprovisionarse de servicios. Sin embargo, en la práctica, las relaciones pueden abarcar un mayor espectro que las operaciones mencionadas. En este ensayo se mencionan algunos elementos que deben ser considerados por las partes cuando se haga la negociación y que quedarán plasmados en el cuerpo del contrato.</p>
Convergencia regional en el índice de desarrollo humano en Colombia
Authors: Ríos Hernández Héctor Fabio , León Nieto Diego Ismael 
Published: November 2015

<p>Una de las preocupaciones básicas acerca de la teoría del crecimiento y desarrollo económico ha sido la de conocer si las diferencias en los niveles de bienestar y riqueza existentes entre países tienden a disminuir o a desaparecer. Desde un debate amplio sobre la teoría de la convergencia y teniendo en cuenta las definiciones y los objetivos del desarrollo humano, este trabajo, mediante la aplicación de la técnica econométrica de datos de panel, pretende encontrar el grado de convergencia regional en Colombia, abordando la importancia que tienen las disparidades en el contexto del desarrollo humano, el cual surge como herramienta fundamental para el crecimiento económico sostenible y generalizado, que además de generar productividad en la economía, puede contribuir en la disminución de las brechas de inequidad. El enfoque de este informe de investigación estará encaminado por los lineamientos neoclásicos, inmersos en el contexto multidimensional del índice de desarrollo humano (IDH).</p><p> </p>
La teoría de la agencia. El caso de una universidad privada en la ciudad de Manizales
Authors: Mackenzie Torres Tania , Buitrago Quintero María Teresa , Giraldo Vélez Patricia , Parra Sánchez José Hernán , Valencia Ramos Jaime Alberto 
Published: November 2015

<p>El objetivo del trabajo fue determinar los factores que explican la relación entre principal y agente (P-A) en una institución de educación superior (IES) de carácter privado en la ciudad de Manizales. El estudio se fundamentó en las bases conceptuales de la corriente neoinstitucional, enmarcada en modelos microeconómicos y neoliberales, interpretados a la luz de la teoría de la agencia. La medición de los factores que explican la relación P-A se dio a través del análisis de datos, y así fue posible confirmar las hipótesis planteadas. La relación P-A en la IES de estudio se explica más por factores motivacionales externos e internos que por el factor salario. Los resultados aseveran la importancia de la alineación de los objetivos para mejorar la eficiencia en la institución.</p>
Criterios para una propuesta de construcción de distritos agroindustriales con enfoque en las alianzas público-privadas
Authors: Zarur Ramos Alberto Luis , Delgado Jaimes Pedro Fernando 
Published: November 2015

<p>Con este artículo, se busca aportar tanto a la reflexión teórica como al diseño de las políticas públicas con enfoque en el desarrollo productivo regional, criterios metodológicos y conceptuales para la construcción de propuestas encaminadas a utilizar las alianzas público-privadas (APP), como soporte estratégico para la promoción de transformaciones productivas, en actividades de la agroindustria dentro de contextos territoriales con características específicas. En este sentido, el artículo parte de la hipótesis acerca de la imposibilidad del desarrollo económico y social desde presupuestos del desarrollo clásico por el que transitaron los países hoy avanzados de Europa y Estados Unidos. Se propone, por tanto, inducir las transformaciones productivas requeridas para un despegue sostenido del desarrollo productivo, empezando por el impulso a la agroindustria a través de la conformación de distritos especializados en dicha producción, con el apoyo de las APP que establece la ley colombiana. Se determina además, que la agroindustria es el camino propicio para generar un desarrollo económico de mediano y largo plazo.</p><p> </p>
Caracterización de la composición en proteína, lípidos, energía y perfiles de ácidos grasos en huevos de tilapia roja (Oreochromis spp.)
Authors: Valbuena-Villarreal Rubén Darío , Zapata-Berruecos Beatriz Elena , Rosado-Puccini Rafael 
Published: November 2015

Luego de considerar el significado de las tilapias en el escenario piscícola nacional, la posibilidad de mejorar los índices de producción es un imperativo técnico y, dentro de estos, focalizar esfuerzos experimentales en la semilla resulta ser una opción estratégica. Con el fin de establecer un referente de base se utilizaron las puestas individuales de 50 hembras de tilapia roja (Oreochromis spp.) para determinar los contenidos en los huevos de proteína (% MS), extracto etéreo (% MS), energía (cal g-1) y los perfiles de ácidos grasos (%), con algunas relaciones de interés analítico. Salvo ciertas variaciones menores, los valores encontrados se ajustan a los registros disponibles para la especie en diferentes estudios, lo que sugiere que las dietas ofrecidas a los reproductores experimentales contienen los mínimos necesarios para asegurar una provisión de nutrientes y energía suficientes para los embriones y las larvas en formación. Se analiza que, como punto de partida, esta serie de datos tiene utilidad para el desarrollo de trabajos destinados a mejorar los estándares de producción de alevinos, considerando que las variaciones en la composición, que pueden ser determinadas sobre los huevos, se pueden utilizar y tienen validez como un indicativo directo de su calidad.
Synergizing Crosswell Seismic and Electromagnetic Techniques for Enhancing Reservoir Characterization
Authors: Katterbauer Klemens , Hoteit Ibrahim , Sun Shuyu 
Published: November 2015

SummaryIncreasing complexity of hydrocarbon projects and the request for higher recovery rates have driven the oil-and-gas industry to look for a more-detailed understanding of the subsurface formation to optimize recovery of oil and profitability. Despite the significant successes of geophysical techniques in determining changes within the reservoir, the benefits from individually mapping the information are limited. Although seismic techniques have been the main approach for imaging the subsurface, the weak density contrast between water and oil has made electromagnetic (EM) technology an attractive complement to improve fluid distinction, especially for high-saline water. This crosswell technology assumes greater importance for obtaining higher-resolution images of the interwell regions to more accurately characterize the reservoir and track fluid-front developments. In this study, an ensemble-Kalman-based history-matching framework is proposed for directly incorporating crosswell time-lapse seismic and EM data into the history-matching process. The direct incorporation of the time-lapse seismic and EM data into the history-matching process exploits the complementarity of these data to enhance subsurface characterization, to incorporate interwell information, and to avoid biases that may be incurred from separate inversions of the geophysical data for attributes. An extensive analysis with 2D and realistic 3D reservoirs illustrates the robustness and enhanced forecastability of critical reservoir variables. The 2D reservoir provides a better understanding of the connection between fluid discrimination and enhanced history matches, and the 3D reservoir demonstrates its applicability to a realistic reservoir. History-matching enhancements (in terms of reduction in the history-matching error) when incorporating both seismic and EM data averaged approximately 50% for the 2D case, and approximately 30% for the 3D case, and permeability estimates were approximately 25% better compared with a standard history matching with only production data.
Biogeochemical Approaches to Assess PAH Pollution in an Urban Waterway
Authors: Cheng Xianhao , Forsythe Jennifer , Peterkin Earl 
Published: November 2015

ABSTRACT: Biogeochemical approaches were applied to enhance the study on polycyclic aromatic hydrocarbon (PAH) pollution in an urban waterway. Chemical characterizations of PAHs in the studied area were identified, geochemical factors were revealed, and related mechanisms were discussed. It was found that, during summer, an early diagenetic process in the sediment could play a major role for the existence of high PAH concentrations, especially high molecular weight PAHs (≥4 rings), in the water column and sediment porewater. This effect could vary with tidal cycling, and higher PAH concentration in the water column would be expected during low tide. Other potential pollution sources were also evaluated in the studied creek. Results showed that pyrogenic sources dominated in the creek, generally. Nevertheless, petroleum products from a metal recycling plant could be an important point source to the waterway during wet weather. Comparing with previous studies in other waterways of the same watershed and published literature suggested that the limited toxicity to the ecosystem was only detected in sediments. More information needs to be collected during low tide for a more objective evaluation of PAH toxicity in the creek.
Glacial melt under a porous debris layer

Published: November 2015

AbstractIn this paper we undertake a quantitative analysis of the dynamic process by which ice underneath a dry porous debris layer melts. We show that the incorporation of debris-layer airflow into a theoretical model of glacial melting can capture the empirically observed features of the so-called Østrem curve (a plot of the melt rate as a function of debris depth). Specifically, we show that the turning point in the Østrem curve can be caused by two distinct mechanisms: the increase in the proportion of ice that is debris-covered and/or a reduction in the evaporative heat flux as the debris layer thickens. This second effect causes an increased melt rate because the reduction in (latent) energy used for evaporation increases the amount of energy available for melting. Our model provides an explicit prediction for the melt rate and the temperature distribution within the debris layer, and provides insight into the relative importance of the two effects responsible for the maximum in the Østrem curve. We use the data of Nicholson and Benn (2006) to show that our model is consistent with existing empirical measurements.
Improving Bridging from Informatics Practice to Theory
Authors: Lehmann C. U. , Gundlapalli A. V. 
Published: November 2015

SummaryBackground: In 1962, Methods of Information in Medicine (MIM) began to publish papers on the methodology and scientific fundamentals of organizing, representing, and analyzing data, information, and knowledge in biomedicine and health care. Considered a companion journal, Applied Clinical Informatics (ACI) was launched in 2009 with a mission to establish a platform that allows sharing of knowledge between clinical medicine and health IT specialists as well as to bridge gaps between visionary design and successful and pragmatic deployment of clinical information systems. Both journals are official journals of the International Medical Informatics Association.Objectives: As a follow-up to prior work, we set out to explore congruencies and interdependencies in publications of ACI and MIM. The objectives were to describe the major topics discussed in articles published in ACI in 2014 and to determine if there was evidence that theory in 2014 MIM publications was informed by practice described in ACI publications in any year. We also set out to describe lessons learned in the context of bridging informatics practice and theory and offer opinions on how ACI editorial policies could evolve to foster and improve such bridging.Methods: We conducted a retrospective observational study and reviewed all articles published in ACI during the calendar year 2014 (Volume 5) for their main theme, conclusions, and key words. We then reviewed the citations of all MIM papers from 2014 to determine if there were references to ACI articles from any year. Lessons learned in the context of bridging informatics practice and theory and opinions on ACI editorial policies were developed by consensus among the two authors.Results: A total of 70 articles were published in ACI in 2014. Clinical decision support, clinical documentation, usability, Meaningful Use, health information exchange, patient portals, and clinical research informatics emerged as major themes. Only one MIM article from 2014 cited an ACI article. There are several lessons learned including the possibility that there may not be direct links between MIM theory and ACI practice articles. ACI editorial policies will continue to evolve to reflect the breadth and depth of the practice of clinical informatics and articles received for publication. Efforts to encourage bridging of informatics practice and theory may be considered by the ACI editors.Conclusions: The lack of direct links from informatics theory-based papers published in MIM in 2014 to papers published in ACI continues as was described for papers published during 2012 to 2013 in the two companion journals. Thus, there is little evidence that theory in MIM has been informed by practice in ACI.
Les Dépravés de Dieu
Authors: Simenel Romain 
Published: November 2015

La transgression est-elle un trait structurant de la catégorie « jeune » au Maroc ? Comment le rapport à la religion, en l’occurrence à l’islam, intervient-il dans la distinction des catégories d’âge social ? À quel point la relation à Dieu diffère-t-elle selon que l’on soit « jeune » ou « homme d’honneur » ? Déconsidéré, voire rejeté par l’islam, le célibat, surtout s’il se prolonge, semble être l’angle de vue le plus pertinent pour explorer les limites de ce qui fait un jeune. Cet article part de l’analyse d’un rituel de traitement du célibat pratiqué dans de nombreuses régions du Sud-Ouest marocain — rituel qui permet de définir la catégorie « jeune » sous l’angle croisé des rapports de genre et de la religion —, avant de développer une réflexion plus générale sur les représentations liées à la jeunesse masculine – notamment dans le rapport qu’elle entretient avec la vie « licite » et le jugement divin. Il s’agit alors de démontrer que dans le Sud marocain, du point de vue religieux, les hommes sont des « deux fois nés ». C’est entre ces deux « naissances », la naissance biologique et le mariage, que se situerait la jeunesse. Elle serait un temps de transgression religieuse durant lequel les jeunes subissent l’influence du cheytan et de l’Occident avant de mieux redevenir musulman. Dépravés de Dieu, ces jeunes s’éloigneraient le plus radicalement possible d’un islam prescriptif pour mieux choisir d’épouser ensuite la religion par le cœur et devenir des hommes en marche vers le paradis grâce au mariage.
La reconstrucción virtual del palacio andalusí de Onda (Castellón): Arquitectura y Territorio
Authors: Garrido Carretero Fidel 
Published: November 2015

<p>This paper presents the virtual reconstruction of the Islamic palace of Onda (Castellón), a site where recent excavations have brought to light an important set of structures dating from the 11th century. Its poor state of preservation allowed a fairly complete reading of the palace plan but there was no hard evidence regarding its elevations. In the context of an ongoing study of the site, a virtual reconstruction of the palace was undertaken in order to facilitate the process of trial and error involved in figuring out its original configuration. A method devised to test reconstructive hypotheses on an active archaeological site is presented, followed by a discussion of results that encompasses the architecture and the urban and regional context of the site.</p>
Ciudades perdidas, ciudades recuperadas. La tecnología al servicio del pasado
Authors: Fernández Ruiz José Antonio , Gómez Robles Lucía 
Published: November 2015

<p>Cities are living entities that change almost daily but its people are aware of it. They forget the state before the great changes and people become accustomed to the new urban image. In a hundred years a city can completely change its appearance and even its essence. This is the case of Granada, where its historic center was heavily modified during the nineteenth century. These changes have been studied by a project analyzing and virtually rebuilding the historic city. The work ranges from the Rey Chico, below the Alhambra palace, to Puerta Real, restoring the image of the city around 1831, based on the engravings and descriptions of romantic travelers, on the previous alignments and transformations in old pictures.</p>

Alternative Fuel Infrastructure and Customer Location Impacts on Fleet Mix and Vehicle Routing
Authors: In Joonhwan , Bell John E. 
Published: November 2015

Abstract
An increase in the use of conventional vehicles in combination with alternative fuel vehicles requires trucking carriers to make a decision on when to use a mixed fleet. The purpose of this article is to investigate how alternative fuel infrastructure and patterns of customer locations influence fleet compositions when minimizing routing costs. The variable-route vehicle refueling problem (VRVRP) for the mixed fleet is formulated as a mixed-integer programming model and solved with an optimization method. A logistic regression is then employed to assess the impacts of both the density of the alternative fuel infrastructure and the patterns of customer locations on the optimal fleet composition. Experimental results reveal that the right fleet mix decision is impacted by customer location patterns and available fuel infrastructure. While alternative fuel trucks were favored over conventional trucks with a dense alternative fuel infrastructure, the likelihood of mixed fleet use varied across different patterns of customer demand locations. Further, our analysis suggests that shippers and trucking carriers should understand the relative benefits and constraints of different geographical dispersions of customers and densities of alternative fuel infrastructures when designing optimal delivery strategies.
