281. Una yihad visual: imágenes hiperreales del terror en las producciones audiovisuales de ISIS - Lucas Reydó
Las recientes producciones audiovisuales del grupo yihadista conocido internacionalmente como Estado Islámico (ISIS, ISIL, o bien EI), presentan ciertas características en sus montajes que no encuentran parangón con aquellas de anteriores grupos terrroristas a lo largo de la historia. El presente ensayo se propone indagar en las formas contemporáneas del terrorismo a partir del análisis semiológico de los videos difundidos por el EI. Para ello, se recurre a las perspectivas teórico-epistemológicas sobre la imagen de Jacques Rancière y Jean Baudrillard para pensar las imágenes producidas por el EI bajo una perspectiva que no las situa ni bajo una dinámica de pura...

282. Single Atoms Preparation Using Light-Assisted Collisions - Yin Hsien Fung; Pimonpan Sompet; Mikkel F. Andersen
The detailed control achieved over single optically trapped neutral atoms makes them candidates for applications in quantum metrology and quantum information processing. The last few decades have seen different methods developed to optimize the preparation efficiency of single atoms in optical traps. Here we review the near-deterministic preparation of single atoms based on light-assisted collisions and describe how this method can be implemented in different trap regimes. The simplicity and versatility of the method makes it feasible to be employed in future quantum technologies such as a quantum logic device.

Pablo Latapí reflexiona sobre la relación entre la investigación educativa y la toma de decisiones políticas en educación. Lo hace a partir de sus propias interacciones con nueve secretarios de educación en México, entre los años 1963 y 2006, como su asesor. Identifica tres funciones en las que el investigador puede aportar a la toma de decisiones: como crítico, como asesor...

284. The Gap between Mapuche Knowledge and School Knowledge in the Mapuche Context - Segundo Quintriqueo Millán; Héctor Torres Cuevas

This article describes the gap between Mapuche and school knowledge in schools of the Ninth Region of Araucanía, Chile. To that end, we examine the implications of a monocultural curriculum for the education of Mapuche children and youth who present different systems of logic for native knowledge and academic knowledge. The methodology used is educational research, based on the multi-method approach. The results provide a knowledge base for understanding the gap between school knowledge and traditional Mapuche knowledge in intercultural educational contexts. The objective is to overcome epistemological issues in the teaching and learning of sciences, through contextualized pedagogical...

285. Measuring Knowledge with Items in Ch’ol and Spanish in Elementary School Children with a Bilingual Intercultural Educational Model - José Bastiani Gómez; Lorena Ruiz-Montoya; Erín Estrada Lugo; Tania Cruz Salazar; José Antonio Aparicio Quintanilla; Flor Marina Bermúdez Urbina
It is assumed that the preferential use of Spanish as language mediator in education, as opposed to an indigenous language, negatively impacts children’s learning. In this study we explore the learning problems that are engendered in children through the use of a language other than their mother tongue in school. A test was conducted in Spanish and Ch’ol, with ten items that focused on linguistic and cultural identity, logic, mathematics, Spanish, history, geography and geometry. Three possible answers were offered, only one of which was correct. The test was administered to 53 fifth-grade children and the same number of sixth-grade...

286. Encrucijadas, preguntas y reflexiones sobre el sentido de educar. La escuela entre el mandato moderno y las realidades sociales complejas - Giménez, Sebastián
Este artícuclo aborda la educación en contextos de pobreza, reflexionando sobre la desigualdad existente entre dos tipos de escuela, dos modelos, dos lógicas, para pensar la educación desde un polo moderno o desde la realidad compleja de los excluidos

287. Las Aboliciones de la Esclavitud en Iberoamérica: El Caso Peruano (1812-1854) - de Vinatea, María Julia
La globalidad del tema de las aboliciones de la esclavitud en Iberoamérica y el largoperiodo que las embarca hacen menester la metodología comparativa. En efecto, laerosión del sistema esclavista arrancó en el espacio iberoamericano a principios delsiglo con Santo Domingo, en 1801, para acabar con la abolición en Cuba en 1886,“joya de las Antillas” del Imperio Español. Otro fuerte del método comparativo esel de aprehender toda la complejidad del espacio ibérico que no sólo correspondea un territorio dado, sino a una cosmovisión dentro de una historia colonial comúncompartida con España. Este método permite plantearnos este espacio tal comolos contemporáneos del...

288. Experiencias Prácticas con el Uso del Lenguaje de Programación Scratch para Desarrollar el Pensamiento Algorítmico de Estudiantes en Chile - Vidal, Cristian L; Cabezas, Carlos; Parra, José H; López, Leopoldo P
The main objective of this article is to present the results of experiments in teaching and learning using an object-oriented programming language. This experiment was performed on students of two secondary schools, one from the city of Viña del Mar and another one from the city of Linares, both in Chile. The experiment showed the potential effects of developing the logic and algorithmic thinking of high school students. This article describes the main properties of the Scratch programming language, as well as its potential advantages to develop the logic and algorithmic thinking of students in Chile, compared to traditional programming...

289. Relación entre la geografía de un país y su economía - Pinto de Prieto, Lyda
La Geografía constituye una materia amplia que penetra en muchas de las fronteras formales del conocimiento, relacionando temas como la Geología, la Climatología, la Agricultura, la Tecnología y la Economía, Cualquier estudio que trate los aspectos humanos de la geografía, en lo que se refiere a la forma de vivir del hombre, sus actividades y, como se relaciona con su medio ambiente, tienen siempre que ver en mayor o menor grado, con problemas de economía. Entre la Geografía y la Economía tradicionalmente no ha existido una relación fuerte, aunque esta relación últimamente ha ido mejorando por la estrecha vinculación que...

290. Control de manipuladores teleoperados - Gutiérrez Carvajal, Ricardo Enrique; Castillo Estepa, Ricardo Andrés
This work is a bibliographical review about different models used to design teleoperated manipulator controllers, there is a quick description of some advantages and disadvantages to implement conventional or intelligent techniques (Neural Networks and Fuzzy Logic) to develop control systems applied to these devices. In addition, here the teleoperation systems are descriptively presented; finally there is a specialized section that shows some control strategies in order to deal with signal delays, inherent to manipulator teleoperation. In the last section some important applications for these systems are described

291. Sistemas inteligentes, ingeniería e hidroinformática - Obregón Neira, Nelson; Fragala, Federico Antonio
This work presents a conceptual framework about the so-called Intelligent Systems regarding their usage in the filed of engineering and particularly in the new discipline of Hydroinformatics. These systems include two branches: Computational Intelligencee and Knowledge-based systems. Within the first ones can be included the paradigms of Artificial Intelligence such as artificial neural networks, genetic algorithms and fuzzy logic. The second ones comprise the rule-based systems and in particular, the decision trees and the (fuzzy) expert systems. In general, all of them offer another possibility aimed at approaching the complex problematic that exist in the study of hydrosystems. Therefore, this...

292. Sexo, masculinidades y las víctimas expiatorias. Las mujeres en contexto de prostitución en los medios: la mirada desde las ONG - Casado Neira, David; Pérez Freire, Silvia
After interviewing 5 experts supporting programs on female prostitution, it was found that they are very critical with the image of prostitution on the media. Our thesis is that the state of many women in context of prostitution is perceived to be built as a victim. They are considered agents without active agency, who are only expected to be told by others. The social debate on prostitution offers us a mirror to identify the actual social imaginary of prostitution and masculinity. This imaginary is founded on two stereotyped poles: the liberated sex worker and hypervictim of human trafficking. If the first responds to the logic of offer/demand...

293. Prehistoria contemporánea. Lógica sacrificial del progreso y sabotaje del destino - Maiso Blasco, Jordi

296. Sub-classical Boolean Bunched Logics and the Meaning of Par - Brotherston, J; Villard, J
We investigate intermediate logics between the bunched logics Boolean BI and Classical BI, obtained by combining classical propositional logic with various flavours of Hyland and De Paiva’s full intuitionistic linear logic. Thus, in addition to the usual multiplicative conjunction (with its adjoint implication and unit), our logics also feature a multiplicative disjunction (with its adjoint co-implication and unit). The multiplicatives behave “sub-classically”, in that disjunction and conjunction are related by a weak distribution principle, rather than by De Morgan equivalence. We formulate a Kripke semantics, covering all our sub-classical bunched logics, in which the multiplicatives are naturally read in terms of...

297. Disproving Inductive Entailments in Separation Logic via Base Pair Approximation - Brotherston, J; Gorogiannis, N
We give a procedure for establishing the invalidity of logical entailments in the symbolic heap fragment of separation logic with user-defined inductive predicates, as used in program verification. This disproof procedure attempts to infer the existence of a countermodel to an entailment by comparing computable model summaries, a.k.a. bases (modified from earlier work), of its antecedent and consequent. Our method is sound and terminating, but necessarily incomplete. Experiments with the implementation of our disproof procedure indicate that it can correctly identify a substantial proportion of the invalid entailments that arise in practice, at reasonably low time cost. Accordingly, it can be...

298. Il viaggio da Messina a Lima di un missionario gesuita italiano nel primo ‘600. Geronimo Pallas (s.j.) e la sua Missión a las Indias (1620) - The travel of an Italian Jesuit missionary from Messina to Lima in the early XVII century. Geronimo Pallas (s.j.) and his Missión a las Indias (1620) - Antonino Colajanni
This article deals with the question of travelling as a mission for institutions with which the traveller has a relationship of deep integration. The peculiar travelling of the Jesuit Geronimo Pallas constitutes a paradigm which will be analyzed by the author. The article deals with the quick and deep learning processes which are activated through the unsettling experience of travelling for long periods in extremely difficult conditions. The traveller is aware of the strong and articulated expectations of the institution which has sent him as a missionary but he also has to face the inescapable logic of “travelling” as such. The missionary, on one hand, sees,...

299. How far does family physician supply correlate with district health system performance? - Robin E. Dyers; Robert Mash; Tracey Naledi

Background: Since 2011, a new cadre of family physicians, with 4 years of postgraduate training, was deployed in the district health services of the Western Cape, and tasked witha considerable range of duties aimed at a general improvement in care and health outcomes. There is a need to evaluate the contribution of these family physicians to the district health system.

Aim: To develop a methodology for describing the correlation between family physician...

300. Baruch Spinoza and the naturalisation of the Bible: An epistemological investigation - Nicolaas J. Gronum
This article investigates the naturalisation of the Bible. Three voices are of special importance in the narrative presented in this article; they are Aristotle (384–322 BC), Rene Descartes (1596–1650) and Baruc Spinoza (1632–1677). This article will investigate the scientific method and metaphysics espoused by each of the three scholars, thereby highlighting changes in scientific method and metaphysics that lead to the naturalisation of the Bible. Firstly, Aristotle pioneered a scientific method (his logic) that would dominate for centuries, as well as a highly influential metaphysics. Secondly, Descartes, witnessing the horrors of the Thirty Years War and seeing first-hand the new...
