AToM: An Analogical Theory of Mind
Authors: Rabkina Irina
Published: July 2017

Theory of Mind (ToM) has been well studied in psychology. It is what gives adults the ability to predict other people’s beliefs, desires, and related actions. When ToM is not yet developed, as in young children, social interaction is difficult. A cognitive system that interacts with humans on a regular basis would benefit from having a ToM. In this extended abstract, I propose a computational model of ToM, Analogical Theory of Mind (AToM), based on Bach’s [2012, 2014] theoretical Structure-Mapping model of ToM. Completed work demonstrates the plausibility of AToM. Future steps include a full implementation and test of AToM.
Fuzzy Logic Model for Digital Forensics: A Trade-off between Accuracy, Complexity and Interpretability
Authors: Shalaginov Andrii
Published: July 2017

The Cyber Crime Investigation is challenged by large and complex data as a key factor of emerging Information and Communication Technologies. The size, the velocity, the variety and the complexity of the data have become so high that data mining approaches are no more efficient since they cannot deal with Big Data. As a result, it can be infeasible to represent specific evidences found in such data in a Court of Law in a human-perceivable manner. Moreover, majority of computational methods result in complex and hardly explainable models. However, Soft Computing, a computing with words, can be beneficial in such case. In particular, hybrid Neuro-Fuzzy is capable of learning understandable and precise fuzzy rule-based model. This paper presents novel improvements of NF architecture and corresponding results.

The aim of this research is to develop a framework for a context-aware adaptive multimodal biometric identification system using agent technology.
Search Strategies as Synchronous Processes (Extended Abstract)
Authors: Talbot Pierre
Published: July 2017

Solving constraint satisfaction problems (CSP) efficiently depends on the solver configuration and the search strategy.

However, it is difficult to customize the constraint solvers because they are not modular enough, and it is hard to create new search strategies by composition.

To solve these problems, we propose spacetime programming, a paradigm based on lattices and synchronous process calculi that views search strategies as processes working collaboratively towards the resolution of a CSP.

We implement the compiler of the language and use it to replace the search module of Choco, a state of the art constraint solver, with an efficient spacetime program that offers better modularity and compositionality of search strategies.
Searching for Well-Behaved Fragments of Halpern-Shoham Logic
Authors: Wałęga Przemysław Andrzej
Published: July 2017

Temporal reasoning constitutes one of the main topics within the field of Artificial Intelligence. Particularly interesting are interval-based methods, in which time intervals are treated as basic ontological objects, in opposite to point-based methods, where time-points are considered as basic. The former approach is more expressive and seems to be more appropriate for such applications as natural language analysis or real time processes verification. My research concerns the classical interval-based logic, namely Halpern-Shoham logic (HS). In particular, my investigation continues recently proposed search for well-behaved - i.e., expressive enough for practical applications and of low computational complexity - HS fragments obtained by imposing syntactical restrictions on the usage of propositional connectives in their languages.

Authors: Koeman Vincent J. , Hindriks Koen V. , Jonker Catholijn M.
Published: July 2017

The main goal of our demonstration is to show how omniscient debugging can be applied in practice to cognitive agents. A concrete implementation of the mechanisms proposed in Koeman et. al [2017] has been created for the GOAL agent programming language in the Eclipse environment, integrated with the source-level debugger of Koeman et. al [2016], thus fully implementing the proposal within a state-of-the-art setting. The implementation will be used together with typical agent programs to demonstrate its practical use.
A Goal-Oriented Meaning-based Statistical Multi-Step Math Word Problem Solver with Understanding, Reasoning and Explanation
Authors: Liang Chao-Chun , Wong Yu-Shiang , Lin Yi-Chung , Su Keh-Yih
Published: July 2017

A goal-oriented meaning-based statistical framework is presented in this paper to solve the math word problem that requires multiple arithmetic operations with understanding, reasoning and explanation. It first analyzes and transforms sentences into their meaning-based logical forms, which represent the associated context of each quantity with role-tags (e.g., nsubj, verb, etc.). Logic forms with role-tags provide a flexible and simple way to specify the physical meaning of a quantity. Afterwards, the main-goal of the problem is decomposed recursively into its associated sub-goals. For each given sub-goal, the associated operator and operands are selected with statistical models. Lastly, it performs inference on logic expressions to get the answer and explains how the answer is obtained in a human comprehensible way. This process thus resembles the human cognitive understanding of the problem and produces a more meaningful problem solving interpretation.
Automated Planning for Urban Traffic Management
Authors: McCluskey Thomas L. , Vallati Mauro , Franco Santiago
Published: July 2017

The global growth in urbanisation increases the demand for services including road transport infrastructure, presenting challenges in terms of mobility. Optimising the exploitation of urban road network, while attempting to minimise the effects of traffic emissions, is a great challenge. SimplyfAI was a UK research council grant funded project which was aimed towards solving air quality problems caused by road traffic emissions. Large cities such as Manchester struggle to meet air quality limits as the range of available traffic management devices is limited. In the study, we investigated the application of linked data to enrich environmental and traffic data feeds, and we used this with automated planning tools to enable traffic to be managed at a region level. The management will have the aim of avoiding air pollution problems before they occur. This demo focuses on the planning component, and in particular the engineering and validation aspects, that were pivotal for the success of the project.
Solving Integer Linear Programs with a Small Number of Global Variables and Constraints
Authors: Dvořák Pavel , Eiben Eduard , Ganian Robert , Knop Dušan , Ordyniak Sebastian
Published: July 2017

Integer Linear Programming (ILP) has a broad range of applications in various areas of artificial intelligence. Yet in spite of recent advances, we still lack a thorough understanding of which structural restrictions make ILP tractable. Here we study ILP instances consisting of a small number of ``global'' variables and/or constraints such that the remaining part of the instance consists of small and otherwise independent components; this is captured in terms of a structural measure we call fracture backdoors which generalizes, for instance, the well-studied class of N-fold ILP instances.

Our main contributions can be divided into three parts. First, we formally develop fracture backdoors and obtain exact and approximation algorithms for computing these. Second, we exploit these backdoors to develop several new parameterized algorithms for ILP; the performance of these algorithms will naturally scale based on the number of global variables or constraints in the instance. Finally, we complement the developed algorithms with matching lower bounds. Altogether, our results paint a near-complete complexity landscape of ILP with respect to fracture backdoors.
Personnel Scheduling as Satisfiability Modulo Theories
Authors: Erkinger Christoph , Musliu Nysret
Published: July 2017

Rotating workforce scheduling (RWS) is an important real-life personnel rostering problem that appears in a large number of different business areas. In this paper, we propose a new exact approach to RWS that exploits the recent advances on Satisfiability Modulo Theories (SMT). While solving can be automated by using a number of so-called SMT-solvers, the most challenging task is to find an efficient formulation of the problem in first-order logic. We propose two new modeling techniques for RWS that encode the problem using formulas over different background theories. The first encoding provides an elegant approach based on linear integer arithmetic. Furthermore, we developed a new formulation based on bitvectors in order to achieve a more compact representation of the constraints and a reduced number of variables. These two modeling approaches were experimentally evaluated on benchmark instances from literature using different state-of-the-art SMT-solvers. Compared to other exact methods, the results of this approach showed an important improvement in the number of found solutions.
Cardinality Encodings for Graph Optimization Problems
Authors: Ignatiev Alexey , Morgado Antonio , Marques-Silva Joao
Published: July 2017

Different optimization problems defined on graphs find application in complex network analysis. Existing propositional encodings render impractical the use of propositional satisfiability (SAT) and maximum satisfiability (MaxSAT) solvers for solving a variety of these problems on large graphs. This paper has two main contributions. First, the paper identifies sources of inefficiency in existing encodings for different optimization problems in graphs. Second, for the concrete case of the maximum clique problem, the paper develops a novel encoding which is shown to be far more compact than existing encodings for large sparse graphs. More importantly, the experimental results show that the proposed encoding enables existing SAT solvers to compute a maximum clique for large sparse networks, often more efficiently than the state of the art.
A Recursive Shortcut for CEGAR: Application To The Modal Logic K Satisfiability Problem
Authors: Lagniez Jean-Marie , Le Berre Daniel , de Lima Tiago , Montmirail Valentin
Published: July 2017

Counter-Example-Guided Abstraction Refinement (CEGAR) has been very successful in model checking large systems. Since then, it has been applied to many different problems. It especially proved to be an highly successful practical approach for solving the PSPACE complete QBF problem. In this paper, we propose a new CEGAR-like approach for tackling PSPACE complete problems that we call RECAR (Recursive Explore and Check Abstraction Refinement). We show that this generic approach is sound and complete. Then we propose a specific implementation of the RECAR approach to solve the modal logic K satisfiability problem. We implemented both a CEGAR and a RECAR approach for the modal logic K satisfiability problem within the solver MoSaiC. We compared experimentally those approaches to the state-of-the-art solvers for that problem. The RECAR approach outperforms the CEGAR one for that problem and also compares favorably against the state-of-the-art on the benchmarks considered.
Solving Stochastic Boolean Satisfiability under Random-Exist Quantification
Authors: Lee Nian-Ze , Wang Yen-Shi , Jiang Jie-Hong R.
Published: July 2017

Stochastic Boolean Satisfiability (SSAT) is a powerful formalism to represent computational problems with uncertainly, such as belief network inference and propositional probabilistic planning. Solving SSAT formulas lies in the same complexity class (PSPACE-complete) as solving Quantified Boolean Formula (QBF). While many endeavors have been made to enhance QBF solving, SSAT has drawn relatively less attention in recent years. This paper focuses on random-exist quantified SSAT formulas, and proposes an algorithm combining binary decision diagram (BDD), logic synthesis, and modern SAT techniques to improve computational efficiency. Unlike prior exact SSAT algorithms, the proposed method can be easily modified to solve approximate SSAT by deriving upper and lower bounds of satisfying probability. Experimental results show that our method outperforms the state-of-the-art algorithm on random k-CNF formulas and has effective application to approximate SSAT on circuit benchmarks.
An Effective Learnt Clause Minimization Approach for CDCL SAT Solvers
Authors: Luo Mao , Li Chu-Min , Xiao Fan , Manyà Felip , Lü Zhipeng
Published: July 2017

Learnt clauses in CDCL SAT solvers often contain redundant literals. This may have a negative impact on performance because redundant literals may deteriorate both the effectiveness of Boolean constraint propagation and the quality of subsequent learnt clauses. To overcome this drawback, we define a new inprocessing SAT approach which eliminates redundant literals from learnt clauses by applying Boolean constraint propagation. Learnt clause minimization is activated before the SAT solver triggers some selected restarts, and affects only some learnt clauses during the search process. Moreover, we conducted an empirical evaluation on instances coming from the hard combinatorial and application categories of recent SAT competitions. The results show that a remarkable number of additional instances are solved when the approach is incorporated into five of the best performing CDCL SAT solvers (Glucose, TC_Glucose, COMiniSatPS, MapleCOMSPS and MapleCOMSPS_LRB).
PODEROSA IGNORANCIA: CELOS Y PRETENSIÓN DE VERDAD EN DOM CASMURRO DE MACHADO DE ASSIS
Authors: Sánchez-Godoy Rubén A.
Published: July 2017

This essay explores the way in which the unproven suspicions of the main character of Dom Casmurro become a monologue that aims to prove the infidelity of his beloved. Using Žižek’s concept of ideology, I propose that this monologue is possible on the basis of the elaboration of an argument that allows to the narrator to produce his object of desire as an ambiguous one, fascinating and unreliable at the same time. Through the literary reconstruction of this argument, that transforms incertitude and suspicion in possibilities of epistemological and moral empowering, Machado discusses and ironizes a masculine perspective that tries to maintain its gender related privileges in a society with increasing feminine mobility.
OJALÁ NUNCA AMANECIERA: GUAPOS Y HOMOSEXUALES EN EL MEDELLÍN DE AIRE DE TANGO
Authors: Orrego Jaime A.
Published: July 2017

Manuel Mejía Vallejo’s Aire de tango (1973) presents the Guayaquil neighborhood as a microcosm and a reflection of transgressions brought on by the process of modernization in Medellin during the first half of the twentieth century. However, the disintegrated environment that appears in the novel is the background of another fragmentation, that of Jairo, its main character. Along with the cultural crisis that unfolds in this neighborhood, there is also a crisis in which Jairo’s sexuality is subjected to the same fragmentation that not only reveals manhood as something elusive and unattainable, but also the homosexual desire.
CARNAVAL DE SODOMA DE PEDRO ANTONIO VALDEZ: RETRATOS Y VESTIDURAS TRAVESTIS
Authors: Penenrey Navarro Julio
Published: July 2017

Cross-dressing and queer identities constitute themes that are ignored and neglected by the literary critic that the novel Carnaval de Sodoma (2002), by Dominican writer Pedro Antonio Valdez has had until now. We will analyze three transvestite characters —Tora, the Baron of the graveyard-La Fortunata and Changsán-Princess of Jade— and examine how the transvestite action destabilize the naturalization and complementarization imaginary that the normative discourse has assigned to the traditional genders (masculine/femenine). We will rethink notions such as gender and sexuality, usually established by the heterocentered thought as fixe and immutable entities.

A New Route for Direct Electroless Ni-P Plating on Magnesium Alloys
Authors: Xuân Vương Bùi
Published: July 2017

This report describes a new route for direct electroless Ni-P plating on magnesium alloys using nickel sulfate as the main salt component. The surface morphology, chemical composition and corrosion resistance of coatings were determined using SEM, EDX and electrochemical polarization techniques. Ni-P coatings with good corrosion resistance and high adhesion were obtained using this route and improved pretreatments. A mixture of H3PO4 and HNO3 was used as a pickling solution for Mg substrate pretreatment. A coarse surface was produced via the developed pickling procedure. A mechanical occlusive force is believed to exist between the coatings and the substrates. Twice activations, K4P2O7 and NH4HF2 as activation components, respectively, were applied for the pretreatment of magnesium alloy plating. An optimal F/O ratio on the Mg substrate surface was obtained by this pretreatment method. The activation film has insoluble partial fluorides which can depress the active points on substrate surface against the reaction of Mg with Ni2+ and H+ in the plating bath. A highly stable bath with pH 5 buffer was identified. The advantages of the developed process include chromium-free, low fluoride, and high bath stability. It is applicable for the production of motorcycle part plating.

The highest plant height (69 cm) and yield attributes viz., branches plant-1 (7.6), pods plant-1 (46.3), pod length (13.5 cm), seed pod-1 (16) and test weight (12.7 g) were recorded with 100% ETc + TGA (200 ppm). Further, 80% ETc + TGA (200 ppm), and 100% ETc + N-acetyl cystein (both 10 and 20 ppm) and 100% ETc + TGA (both 100 and 200 ppm) produced comparable plant height. However, 80% ETc + N-acetyl cystein (both 10 and 20 ppm), 80% ETc + TGA (both 100 and 200 ppm), 100% ETc + N-acetyl cystein (both 10 and 20 ppm), 100% ETc + TGA (100 ppm) and 100% ETc + TGA (200 ppm) recorded at par branches plant-1, pods plant-1, pod length and test weight of fenugreek. Highest seed and biological yield of fenugreek were recorded with 100% ETc + Nacetyl cystein (20 ppm), which was at par with 100% ETc + N-acetyl cystein (10 ppm) and 100% ETc + TGA (both 100 and 200 ppm). Maximum water use recorded at 100% ETc with or without bioregulators, whereas maximum water use efficiency was recorded with 60% ETc + N-acetyl cystein (20 ppm) followed by 60% ETc + N-acetyl cystein (10 ppm).

Obesity is a major public health problem worldwide especially due to the metabolic disorders which seem to be induced by an excessive amount of adipose tissue. Therefore attention was focused on evaluating the role of bariatric surgery in order to offer a better control of the comorbidities such as diabetes mellitus, arterial hypertension or dyslipidemia which are widely accepted as causes of increased morbidity and mortality among obese patients. Once these benefits have been widely demonstrated, attention was focused on studying the potential protective role of bariatric surgery against development of various malignancies such a breast, endometrial, pancreatic or even colorectal cancer. This is a literature review regarding the potential protective role of bariatric surgery against breast cancer among obese women worldwide.
Efficiency and equity in Learning Communities and schools
Authors: Prieto-Flores Òscar , Santa Cruz Iñaki
Published: July 2017

Abstract: Traditionally, school efficiency has been measured as a function of educational production. In the last two decades, however, studies in the economics of education have indicated that more is required to improve school efficiency: researchers must explore how significant changes in school organization affect the performance of at-risk students. In this paper we introduce Henry Levin’s adoption of the X-efficiency approach to education and we describe the efficient and cost-effective characteristics of one Learning Communities Project School that significantly improved its student outcomes and enrollment numbers and reduced its absenteeism rate to zero. The organizational change that facilitated these improvements defined specific issues to address. Students’ school success became the focus of the school project, which also offered specific incentives, selected teachers, involved parents and community members in decisions, and used the most efficient technologies and methods. This case analysis reveals new two elements—family training and community involvement—that were not explicit parts of Levin’s adaptation. The case of the Antonio Machado Public School should attract the attention of both social scientists and policy makers. Eficiencia y equidad en las Comunidades de Aprendizaje y las escuelas Resumen: Tradicionalmente, la eficiencia de las escuelas se ha abordado desde funciones de producción educativa. Sin embargo, en los últimos veinte años algunos estudios del campo de la Economía de la educación han señalado que para la mejora de la eficiencia escolar es necesario ir más allá y explorar cómo determinados cambios organizativos en una escuela pueden afectar positivamente al rendimiento de los estudiantes más desaventajados. En este trabajo, introducimos cómo Henry Levin adoptó la perspectiva de la Eficiencia-X al mundo educativo y explicamos las características de alta eficiencia y de coste-efectividad de una escuela del Proyecto de Comunidades de Aprendizaje que mejoró substancialmente los resultados educativos de sus estudiantes, el número de matriculados y redujo la tasa de absentismo a casos puntuales. Estas mejoras se llevaron a cabo a través de un cambio organizativo centrado en algunos elementos como el establecimiento de un objetivo claro –poniendo el éxito educativo del alumnado en el centro del proyecto escolar-, incentivos motivacionales específicos, selección del profesorado, involucración de las familias y la comunidad en todas las decisiones del centro y el uso de las tecnologías o metodologías más eficientes. El análisis de este estudio de caso también nos demuestra cómo existen dos características que no quedan explícitas en la adaptación de Levin. Éstas son la formación de familiares y la involucración de la comunidad. El caso de la escuela pública Antonio Machado no puede pasar desapercibido por la comunidad científica ni por la Administración pública.

Resumen: El objetivo de este trabajo es relacionar el consumo de sustancias como el alcohol, el tabaco, y los psicofármacos con la percepción de riesgos como, sufrir un accidente de tráfico, padecer problemas de salud transitorios, problemas legales, dificultad en las relaciones interpersonales, disminución de la capacidad para realizar tareas y problemas de salud graves e irreversibles. Con un diseño expost-facto prospectivo de grupo único (Montero y León, 2007), y un cuestionario elaborado a partir del cuestionario utilizado en el estudio “Andaluces ante las drogas” (Navarro, Alonso y Fernández, 2005), se recogió información sociodemográfica y sobre la percepción de riesgo ante el consumo de distintas sustancias de 1011 estudiantes de la Universidad de Córdoba. Los resultados señalan que en general los jóvenes universitarios que más consumen alcohol, tabaco y psicofármacos son los que valoran con una puntuación más baja los posibles riesgos derivados del consumo. Además, el modelo de regresión para cada una de las sustancias indica que una valoración baja en determinados riesgos puede predecir un mayor consumo de la misma. En conclusión, dadas las tendencias de consumo de drogas en estudiantes universitarios y la baja percepción del riesgo de ciertas consecuencias negativas derivadas del mismo sería conveniente poner en marcha estrategias preventivas en el ámbito universitario. Analysis of legal drugs consumption like alcohol, tobacco and psycho-drugs, and risk perception in University young people Abstract: The aim of this study is to relate the consumption of legal substances like alcohol, cigarettes, and psycho-drugs with the perception of risks such like traffic accidents, the suffering of temporary health problems, legal problems, difficulty in the interpersonal relations, decrease of the capacity to realize tasks and irreversible health problems. With a prospective expost-facto design of only one group (Montero & León, 2007), and a questionnaire elaborated from the questionnaire used in the study “Andaluces ante las drogas” (2005), relevant socio-demographic and risk perception information was collected regarding the consumption of different substances in 1011 students of the University of Córdoba. The results revealed university people that generally consume more alcohol, cigarettes and psycho-drugs are those that value with a lower punctuation the possible risks derived from the consumption. Besides, the model of regression for each one of the substances indicated that a low assessment in determined risks can predict a main consumption of these. As a conclusion, given the trends of drugs consumption in university students and the low perception of the risk of its negative consequences, it would be convenient to set up preventive strategies in the university field.
Egalitarian dialogue and instrumental dimension. Two princi- ples of dialogic learning in the classroom
Authors: Racionero Plaza Sandra
Published: July 2017

Abstract: Dialogic conceptualizations of learning have rapidly arisen in the last two decades. Building upon Vygotsky’s socio-cultural psychology, these theories emphasize that people make meaning in interaction with others, where language is the main mediational tool. One of those accounts is the theory of “dialogic learning” (Flecha, 2000). This article explores two of the principles of dialogic learning: egalitarian dialogue and instrumental dimension, through the meanings that a group of elementary school children gave to learning in interactive groups, a practice of dialogic learning in the classroom. The data revealed the meanings that students gave to those two principles of dialogic learning and how each of those principles gets manifested in interactive groups. Regarding egalitarian dialogue, children perceived that participants in interactive groups hold validity claims, engage in communicative action, and care about the effects and context of the interactions. As for the principle of instrumental dimension, the students pointed out multiple ways in which dialogue act as a tool to learn more, for example, facilitating the identification of gaps and errors in one’s reasoning and fostering the development of communicative abilities. Diálogo igualitario y dimensión instrumental. Dos principios del aprendizaje dialógico en el aula Resumen: En las dos últimas décadas han surgido con rapidez conceptualizaciones dialógicas del aprendizaje. Basándose en la psicología socio-cultural de Vygotsky, estas teorías enfatizan que las personas crean significado en la interacción social, donde el lenguaje es la principal herramienta mediacional. Una de esas teorías es la del “aprendizaje dialógico” (Flecha, 2000).Este artículo explora dos de los principios del aprendizaje dialógico: diálogo igualitario y dimensión instrumental, a través de los significados que un grupo de niñas y niños de educación primaria dan a aprender en grupos interactivos, una práctica de aprendizaje dialógico en el aula. Los datos revelaron lo que significa para las y los estudiantes esos dos principios del aprendizaje dialógico, así como la forma cómo cada uno de ellos se manifiesta en los grupos interactivos. Relacionado con el diálogo igualitario, las niñas y niños percibieron que las y los participantes en grupos interactivos tienen pretensiones de validez, participan de acción comunicativa, y se preocupan por los efectos y el contexto de las interacciones. Sobre el principio de dimensión instrumental, las y los estudiantes destacaron múltiples formas en las que el diálogo actúa como herramienta para aprender más, por ejemplo facilitando la identificación de lagunas y errores en el propio razonamiento y fomentando el desarrollo de habilidades comunicativas.
Mejora en algunas dimensiones de salud percibida en pacien- tes con fibromialgia mediante la aplicación de un programa de meditación mindfulness
Authors: Franco Justo Clemente , Mañas Mañas Israel , Justo Martínez Eduardo
Published: July 2017

Resumen: En este estudio se analizan los efectos que un programa de meditación para el desarrollo de la conciencia plena (mindfulness), puede tener sobre la salud percibida en un grupo de pacientes diagnosticados con fibromialgia. Participaron 33 pacientes diagnosticados de fibromialgia. Se realizó un diseño cuasiexperimental con medición pretest-postest-seguimiento, con un grupo experimental y un grupo control. Como instrumento de evaluación se utilizó el Cuestionario SF-36. Los análisis estadísticos realizados muestran una mejora en las dimensiones funcionamiento físico, dolor corporal, salud general, funcionamiento social, rol emocional, salud mental, y componente mental una vez finalizada la intervención. Estas mejoras se mantienen en la evaluación de seguimiento realizada tres meses después de finalizada la intervención. Estos resultados son acordes con otras investigaciones donde se ha comprobado la eficacia de las técnicas de mindfulness en la mejora de pacientes con fibromialgia. No obstante, el estudio presenta varias limitaciones que habría que subsanar en sucesivas investigaciones para dotar de mayor validez a los resultados obtenidos. Perceived health improvement through a mindfulness meditation development program in fibromyalgia patients Abstract: This study analyzes the effects of a mindfulness development meditation program on perceived health in a group of patients diagnosed with fibromyalgia. Thirty-three patients diagnosed with fibromyalgia participated. A quasi-experimental pretest/posttest/follow-up design was carried out, with one experimental group and one control group. The SF-36 Questionnaire was used as the evaluation instrument. The statistical analyses done show an improvement in the dimensions physical functioning, bodily pain, general health, social functioning, role emotional, mental health, and mental component at the end of the intervention. These improvements are maintained in the follow-up test given three months after intervention. These results are in agreement with other studies which have found mindfulness techniques to be effective in improving patients with fibromyalgia. Nevertheless, the study shows various limitations that would have to be corrected in successive studies to bring more validity to the results.

Detectando consumo de drogas en adolescentes mediante un programa de simulación 3D Abstract: This work presents a new 3D simulation program, called Mii School, and its application to the detection of problem behaviours appearing in school settings. We begin by describing some of the main features of the Mii School program. Then, we present the results of a study in which adolescents responded to Mii School simulations involving the consumption of alcoholic drinks, cigarettes, cannabis, cocaine, and MDMA (ecstasy). We established a “risk profile” based on the observed response patterns. We also present results concerning user satisfaction with the program and the extent to which users felt that the simulated scenes were realistic. Lastly, we discuss the usefulness of Mii School as a tool for assessing drug use in school settings. Resumen: Se presenta en este trabajo un nuevo programa de simulación 3D llamado Mii School y su aplicación para la detección de conductas problemáticas que aparecen en contextos escolares. Comenzamos describiendo algunas de las principales características del programa Mii School. A continuación, se presentan los resultados de un estudio con adolescentes en el cual éstos respondieron a situaciones simuladas de Mii School relacionadas con el consumo de bebidas alcohólicas, tabaco, cannabis, cocaína y MDMA (éxtasis). Se estableció un “perfil de riesgo” fundamentado en los patrones de respuesta observados. Además, se presentan los resultados concernientes a la satisfacción de los participantes con el programa y hasta qué punto los participantes consideraron como realistas las distintas escenas simuladas. Finalmente, se discute la utilidad de Mii School como una herramienta de evaluación de consumo de drogas en contextos educativos
El legado de Luria y la neuropsicología escolar
Authors: Manga Dionisio , Ramos Francisco
Published: July 2017

Resumen: Se revisa la historia de la neuropsicología aplicada al trabajo con los niños. Diversos autores se han mostrado partidarios de aplicar la neuropsicología a los centros educativos, especialidad que algunos han llamado “neuropsicología escolar”. Desde que inicialmente así se la denominó (Hynd y Obrzut, 1981), han tenido lugar notables avances respecto al campo e identidad profesional de esta especialidad. La obra de Luria continúa teniendo una gran influencia internacional. Luria ha contribuido a la comprensión neuropsicológica del individuo y de la práctica profesional. Como actividad profesional, la neuropsicología escolar se ocupa de la evaluación, diagnóstico e intervención en estudiantes que tienen dificultades en sus aprendizajes y/o muestran trastornos de comportamiento en su centro escolar. En los últimos años se viene recomendando una evaluación neuropsicológica comprehensiva de cara a la intervención en el centro escolar. Existen procedimientos más nuevos de evaluación neuropsicológica infantil, los cuales representan aplicaciones innovadoras del modelo conceptual de Luria. La investigación y avances de los estudios de neuroimagen nos permiten conocer mejor los cambios del cerebro en desarrollo. The Luria’s legacy and school neuropsychology Abstract: This article reviews the history of neuropsychology applied to work with children. Several authors have advocated for the application of neuropsychology to the school centres, a specialty some have called “school neuropsycology”. Since the term was initially introduced (Hynd & Obrzut, 1981), considerable advances have arisen regarding the field and professional identity of this specialty. Luria’work continues to have a strong international influence. Luria has served for neuropsychological understanding of the individual and for the professional practice. As professional activity, the school neuropsychology focuses in assessing, diagnosing, and intervening with students who are experiencing learning difficulties and/or behaviour disorders in academic setting. In recent years, a comprehensive neuropsychological assessment for intervention is recommended within a school setting. Newer neuropsychological assessment procedures for children represent innovative applications of Luria’s conceptual model. Research and advances in neuroimaging allow us to view how the developmental brain changes.

Resumen: Este trabajo investiga las diferencias de género en dos dimensiones del estatus social en el grupo, la preferencia social y la popularidad percibida, en una muestra de 274 adolescentes de 11 aulas de 3º y 4º de la ESO (119 chicos, 155 chicas) de dos centros de la provincia de Sevilla. En primer lugar, se ponen en relación las dos dimensiones de estatus con diversos atributos personales; en segundo lugar, se analizan las diferencias de género asociadas a esta estructura relacional. Los resultados muestran patrones de correlación que diferencian la preferencia social y la popularidad, así como patrones correlaciónales diferentes por género para cada una de las dimensiones analizadas. Preference and popularity: differential patterns by gender in the correlates of high status Abstract: This study explores gender differences in two dimensions of social status in the group, social preference and perceived popularity in a sample of 274 adolescents from 11 classes of 3 and 4 of the ESO (119 boys, 155 girls) from two schools in the province of Seville. First, put on the two dimensions of status with various personal attributes, and secondly, we analyze gender differences associated with the relational structure. The results show correlation patterns that differentiate the social preference and popularity, as well as different correlational patterns by gender for each of the dimensions analyzed.
