Heart rate variability feature selection in the presence of sleep apnea: An expert system for the characterization and detection of the disorder

We introduce a sleep apnea characterization and classification approach based on a Heart Rate Variability (HRV) feature selection process, thus focusing on the characterization of the underlying process from a cardiac rate point of view. Therefore, we introduce linear and nonlinear variables, namely Cepstrum Coefficients (CC), Filterbanks (Fbank) and Detrended Fluctuation Analysis (DFA). Logistic Regression, Linear Discriminant Analysis and Quadratic Discriminant Analysis were used for classification purposes.The experiments were carried out using two databases. We achieved a per-segment accuracy of 84.76% (sensitivity = 81.45%, specificity = 86.82%, AUC = 0.92) in the Apnea-ECG Physionet database, whereas in the HuGCDN2014 database, provided by the Dr. Negrín University Hospital (Las Palmas de Gran Canaria, Spain), the best results were: accuracy = 81.96%, sensitivity = 70.95%, specificity = 85.47%, AUC = 0.87. The former results were comparable or better than those obtained by other methods for the same database in the recent literature.We have concluded that the selected features that best characterize the underlying process are common to both databases. This supports the fact that the conclusions reached are potentially generalizable. The best results were obtained when the three kinds of features were jointly used. Another notable fact is the small number of features needed to describe the phenomenon. Results suggest that the two first Fbanks, the first CC and the first DFA coefficient are the variables that best describe the RR pattern in OSA and, therefore, are especially relevant to extract discriminative information for apnea screening purposes.

Determination of steroid hormones in fish tissues by microwave-assisted extraction coupled to ultra-high performance liquid chromatography tandem mass spectrometry

Steroid hormones produce adverse effects on biota as well as bioaccumulation in fish and seafood, making it necessary to develop methodologies to evaluate these compounds in samples related to the food chain. This work presents an analytical method for evaluating 15 steroid hormones in fish tissue. It is based on microwave-assisted extraction and solid-phase extraction coupled to ultra-high-performance liquid chromatography tandem mass spectrometry (MAE-SPE-UHPLC-MS/MS). The proposed method shows appropriate detection limits (0.14–49.0ngg−1), recoveries in the range of 50% and good repeatability. After optimization, the method was applied to different tissues from two small fishes of the Canary Islands that constitute an important level of the food web (Boops boops and Sphoeroides marmoratus) and were exposed to the outfall of the Las Palmas de Gran Canaria wastewater treatment plant. The concentrations of eight detected compounds ranged from below the quantification limits to 3.95μgg−1.

Searching for new serum marker: Red blood cell distribution width (RDW) as predictor of severity in acute pancreatitis

Palmprint based personal identification has gained preference over other biometric modalities due to its ease of acquisition, high user acceptance and reliability. This paper presents a palmprint based identification approach which uses the textural information available on the palmprint by employing a feature level fusion of contourlet transform (CT) and non-subsampled contourlet transform (NSCT). The proposed algorithm captures both local and global details in a palmprint as a compact fixed length palm code. After establishing the region of interest (ROI), the two-dimensional (2-D) spectrum is divided into fine slices using iterated directional filterbanks. Next, directional energy component for each block from the decomposed subband outputs is computed separately for the two transforms. The features from both domains are then fused at feature levels. Palmprint matching is then performed using normalized Euclidean distance classifier. The algorithm is tested on complete database of 7752 palm images of Polytechnic University of Hong Kong, and 500 palm images of GPDS Hand database from University of Las Palmas de Gran Canaria. The experimental results were compiled for features based upon individual transforms and fused one. CT based approach demonstrated the decidability index of 2.7734 and equal error rate (EER) of 0.2333% while NSCT based approach depicted decidability index of 2.8125 and EER of 0.1604% on palm database of Polytechnic University of Hong Kong. Similarly, CT based approach demonstrated the decidability index of 2.6212 and equal error rate (EER) of 0.7082% while NSCT based approach depicted decidability index of 2.7278 and EER of 0.5082% on GPDS hand database. The multimodal approach based upon feature fusion achieved decidability index of 2.8914 and EER of 0.1563% on database of Polytechnic University of Hong Kong and decidability index of 2.7956 and EER of 0.3112% on GPDS hand database. The quantitative measures confirm progressive improved results in three approaches for both the databases.

Anomia and Displacement of Responsibility as Determinants of Tourist Company Managers’ Non-Involvement in Alleviating Poverty

The economic transformation produced by tourism sometimes has a positive influence on reducing poverty, but other times it does not. Discovering the reasons for this difference is highly relevant. In searching for these reasons, this study will focus on an important actor in tourism management, the manager. Specifically, the study will analyze how a certain negative mood state, anomia, influences the fact that managers do not consider it advisable for their companies to become involved in reducing poverty. The term future managers has been used as a proxy variable for managers. In addition, the study will also examine whether a moral disengagement mechanism, displacement of responsibility, is a mediator variable in this relationship. Covariance-based structural equation modeling was applied to a sample of 422 students in their last year of the Tourism degree at two universities, Las Palmas de Gran Canaria (Spain) and Ibn-Zohr-Agadir (Morocco). The results show that all the proposed hypotheses are supported.

La Educación para la Salud en la formación de maestros desde el Espacio Europeo de Educación Superior

El maestro es una pieza clave para el desarrollo de la Promoción y Educación para la Salud en la escuela, por lo que su formación en esta materia resulta fundamental. Los nuevos títulos de grado adaptados al Espacio Europeo de Educación Superior (EEES), contemplan la inclusión del módulo de formación básica, Infancia, Salud y Alimentación, en el Grado en Educación Infantil, mientras que no se establece ningún requisito para incorporar en el Grado en Educación Primaria aspectos relacionados con la salud. La implantación de estos nuevos planes de estudio ha dado lugar a la primera cohorte de graduados, por lo que el objetivo de nuestro trabajo es identificar los conocimientos, necesidades de formación y capacidades percibidas respecto a la Promoción y Educación para la Salud de nuestros estudiantes, y analizar las diferencias en base a la titulación cursada. Se realizó un estudio observacional descriptivo transversal. La población quedó constituida por la totalidad de alumnos de 4º curso de los Grados en Educación Infantil y en Educación Primaria. El instrumento de recogida de datos fue un cuestionario elaborado con motivo de esta investigación. Los resultados ponen de manifiesto diferencias estadísticamente significativas entre los estudiantes del Grado en Educación Infantil y los del Grado en Educación Primaria, en los conocimientos sobre la inclusión de contenidos de salud en el curriculum y sobre las Escuelas Promotoras de Salud; asimismo, los estudiantes del Grado Infantil percibieron tener una mejor formación metodológica, y una mayor capacitación para educar en hábitos saludables. Todo ello parece indicar que la inclusión de una asignatura de formación básica de Educación para la Salud en el plan de estudios del Grado en Educación Infantil ha contribuido a una mejor percepción de los conocimientos y capacidades necesarias para desarrollar estrategias de Promoción y Educación para la Salud en la escuela.

En esta investigación presentamos una breve documentación sobre la Catedral de Las Palmas de Gran Canaria en relación a la figura de Diego Durón de Ortega y un resumido estudio sobre las marcas de agua de su producción litúrgica conservadas en el archivo de la mencionada catedral.

Incidence of anthropometric variables on the performance of top Optimist sailors

The aim of this study was to determine the anthropometric profile of top Optimist sailors to examine how anthropometric variables influence their performance, taking the wind conditions into account. The study comprised 180 sailors (158 males and 22 females) aged 11-15 years competing in the Optimist World Sailing Championship held in Las Palmas de Gran Canaria, Spain, from 23 July to 3 August 2003. A descriptive correlational design was used. Assessments were made before and during the championship. The variables studied were body weight, height, arm span, lengths, fat tissue, muscle tissue, somatotype and performance level, in relation to race finishing place. The mean characteristics presented by the Top Group (sailors ranked 1 to 45) were: body weight (48.3 ± 6.4 kg), height (159.9 ± 5.4 cm), arm span (167.4 ± 6.5 cm), trunk length (37.2 ± 3 cm), lower limb length (90.7 ± 3.9 cm), fat tissue (10.5 ± 1.6%), muscle tissue (45.5 ± 2.1%) and somatotype (endomorphy 2.4 ± 0.9; mesomorphy 4 ± 2.5 and ectomorphy 3.3 ± 0.9). A close relation was observed between finishing place and the variables of weight, height, age, arm span, lower limb length, upper arm girth, sum of skinfolds, muscle weight, bone weight and residual weight. Top sailors tend to be meso-ectomorphic, with significant values for muscle mass and linearity and low fat content.

Forum participation plugin for Moodle: Development and Discussion

At present, a large amount of software has been created to analyze social networks, such as libraries to access online social networking APIs, software to draw graphs and tools to use and analyze networks. In fact, and because of the use of Moodle as standard Learning Management System at the University of Las Palmas de Gran Canaria, in 2009 was born the idea of creating a plugin for Moodle capable of analyzing forums in which students participate and of identifying the major players within the student network. This work is about the present state of such plugin, which provides useful information to teachers so that, through the use of social network analysis, allows them to make decisions to improve and promote participatory education. Here, we show the application of the plugin to three case studies, in two different universities, which allowed to evaluate its usefulness and to compare the information according to the variables that influenced each case study.

Design and manufacture of structured surfaces by electroforming

Functional surface texturizing is increasingly demanded by multiple industrial sectors because it allows to achieve properties that significantly improve the functional characteristics of many products. The surfaces structured with geometric details at micrometric scale are allowing a selective modification of their properties. The electroforming process is acquiring a major role in the manufacture of microstructures, due to its great capacity for reproduction of details. The University of Las Palmas de Gran Canaria has extensive experience in rapid tooling through the electroforming process and is collaborating with the University of Cádiz in the ELECTROTEX project to Study of the Tribological Behaviour of Textured Surfaces by SEDM. This collaboration consists of the development of a SEDM electrode with a structured surface for the machining of test specimens for tribological tests.

Association between the p.Thr1406Asn polymorphism of the carbamoyl-phosphate synthetase 1 gene and necrotizing enterocolitis: A prospective multicenter study.

The p.Thr1406Asn (rs1047891) polymorphism of the carbamoyl-phosphate synthetase 1 (CPS1) gene has been linked to functional consequences affecting the downstream availability of the nitric oxide precursor L-arginine. L-arginine concentrations are decreased in preterm infants with necrotizing enterocolitis (NEC). In this multicenter prospective study, we investigated the association of the p.Thr1406Asn polymorphism with NEC in 477 preterm infants (36 cases of NEC) from 4 European neonatal intensive care units (Maastricht, Las Palmas de Gran Canaria, Mantova, and Milan). Allele and genotype frequencies of the p.Thr1406Asn polymorphism did not significantly differ between the infants with and without NEC. In contrast, the minor A-allele was significantly less frequent in the group of 64 infants with the combined outcome NEC or death before 34 weeks of corrected gestational age than in the infants without the outcome (0.20 vs. 0.31, P = 0.03). In addition, a significant negative association of the A-allele with the combined outcome NEC or death was found using the dominant (adjusted odds ratio, aOR: 0.54, 95% CI 0.29–0.99) and the additive (aOR 0.58, 95% CI 0.36–0.93) genetic models. In conclusion, our study provides further evidence that a functional variant of the CPS1 gene may contribute to NEC susceptibility.

PROPIEDADES PSICOMÉTRICAS DE LA BATERÍA DE EVALUACIÓN DE PROCESOS COGNITIVOS Y DE LECTURA EN ADULTOS CON DISLEXIA (BEDA)

Abstract:PSYCHOMETRIC PROPERTIES OF ASSESSMENT BATTERY OF DYSLEXIA IN ADULTS (BEDA)This study analyzed the psychometric properties of the Assessment Battery of Dyslexia in Adults (BEDA). Dyslexia persists into adulthood and the assessment should focus also on the underlying cognitive processes involved in dyslexia. Therefore, valid and reliable instruments tools to detect and assess adults with dyslexia are needed. BEDA was designed as a computer-assisted tool developed with web-based technology for the assessment of cognitive processes involved in university students with dyslexia (i.e., phonological awareness, orthographic processing, processing speed, lexical access, working memory and semantic processing). The standardization of BEDA has been conducted with undergraduate degree, master and PhD students from three Spanish universities (University of La Laguna, University of Girona and University of Las Palmas de Gran Canaria). Finally, we propose that BEDA is part of an e-learning platform (Platform for Assistance and Intervention Dyslexia in Adults: PIADA), along with other identification and assistance tools, with the aim that can be used by teachers and university students, and thus help to meet the challenge to provide university students a resource that enables the identification of dyslexia and provide information to teachers on strategies and guidelines with students with reading disabilities.Keywords: Psychometric properties, dyslexia, adults, BEDA multimedia battery, computerassisted assessment.Resumen:El presente trabajo analiza las propiedades psicométricas de la Batería de Evaluación de Dislexia en Adultos (BEDA). La dislexia puede persistir en la vida adulta y su identificación va a depender, entre otras consideraciones, de la evidencia de déficit en los procesos cognitivos que subyacen a la misma. Por tanto, se hace necesario contar con instrumentos estandarizados válidos y fiables con los que poder identificar la presencia de dislexia en la población adulta. Con este objetivo se diseñó BEDA, la cual puede definirse como una herramienta basada en tecnología web que permite evaluar y representar los déficits cognitivos (en conciencia fonológica, procesamiento ortográfico, velocidad de procesamiento, acceso al léxico, memoria de trabajo y procesamiento semántico), presentados por estudiantes universitarios con dislexia. La estandarización de BEDA se ha llevado a cabo con estudiantes universitarios de grado, máster y doctorado de tres universidades españolas (Universidad de La Laguna, Universitat de Girona y Universidad de Las Palmas de Gran Canaria). Por último, planteamos que BEDA forme parte de una plataforma e-learning (Plataforma de Intervención y Asistencia de Dislexia en Adultos: PIADA), junto con otros instrumentos de identificación y asistencia, con el objetivo de que pueda ser utilizada por profesores y estudiantes universitarios, y de esta manera contribuir a dar respuesta al reto que supone proporcionar al alumnado universitario un recurso que posibilite la identificación de la dislexia, así como ofrecer información al profesorado sobre estrategias y pautas de actuación con el alumnado que presenta esta dificultad.Palabras claves: propiedades psicométricas, dislexia, adultos, batería multimedia BEDA, identificación.

ASPECTOS SOCIO-EMOCIONALES Y SALUD MENTAL Y FÍSICA PERCIBIDAS EN PERSONAS MAYORES

El objetivo del presente trabajo ha sido determinar la relación entre aspectos socioemocionales y la salud mental y salud física percibidas por los participantes de un programa universitario para mayores (Peritia et Doctrina de la Universidad de Las Palmas de Gran Canaria). Se han analizado estos elementos por la importancia que tienen en la calidad de vida de las personas mayores. Para ello se aplicaron los cuestionarios de Estrategias Cognitivo-Emocionales Moldes (Hernández-Guanir, 2010), el CTI, Inventario de Pensamiento Constructivo (Epstein, 2007) y el Cuestionario de Salud SF-36 (adaptación española de Alonso, et al. 1995).Los resultados nos indican que la salud mental percibida por el grupo de participantes está influida de forma significativa por determinadas variables: de forma directa con la emotividad y la capacidad de sobreponerse; mientras que la evaluación selectiva negativa, la justificación de los fallos, la negatividad, la discordancia, la defensividad y el hipercontrol anticipatorio muestran una relación significativa inversa.Por el contrario, frente a esta valoración subjetiva de la salud mental percibida, los resultados nos desvelan que la salud física percibida no guarda relación significativa con ninguna variable.

Ubiquitous knowledge and experiences to foster EFL learning affordances

ABSTRACTThis article explores the implementation of experiential learning affordances to improve skills in English as a Foreign Language (EFL) in higher education. The administration of an online anonymous survey to 100 students of different undergraduate degrees presents current learning reflections from EFL students at the Universidad de Las Palmas de Gran Canaria (ULPGC, Spain) with regards to their active learning skills in their compulsory EFL course programmes. The findings demonstrate that students' motivation remains essential at the time of learning a foreign language. Equally, intrinsic motivation is linked to improving learners' communicative competence in English by means of using individual and interactive learning strategies, which at the same time participate in ubiquitous learning (u-learning) environments that happen anywhere and at any time in order to promote team activities outside the institutional times and places.

Paediatric cardiac surgery in a peripheral European region: is a joint programme a safe alternative to regionalisation?

In 2007, a partnership was initiated between a small-volume paediatric cardiac surgery unit located in Las Palmas de Gran Canaria, Spain, and a large-volume cardiac surgery unit located in Milan, Italy. The main goal of this partnership was to provide surgical treatment to children with CHD in the Canary Islands. An operative algorithm for performing surgery in elective, urgent, and emergency cases was adopted by the this joint programme. Demographic and in-hospital variables were collected from the medical records of all the patients who had undergone surgical intervention for CHD from January, 2009 to March, 2013. Data were introduced into the congenital database of the European Congenital Heart Surgeons Association Congenital Database and the database was interrogated. In total, 65 surgical mission trips were performed during the period of this study. The European Congenital Heart Surgeons Association Congenital Database documented 214 total patients with a mean age at operation of 36.45 months, 316 procedures in total with 198 cardiopulmonary bypass cases, 46 non-cardiopulmonary bypass cases, 26 cardiovascular cases without cardiopulmonary bypass, 22 miscellaneous other types of cases, 16 interventional cardiology cases, six thoracic cases, one non-cardiac, non-thoracic procedure on a cardiac patient with cardiac anaesthesia, and one extracorporeal membrane oxygenation case. The 30-day mortality was 6.07% (13 patients). A joint programme between a small-volume centre and a large-volume centre may represent a valid and reproducible model for safe paediatric cardiac surgery in the context of a peripheral region.

Académicos gestores en la universidad actual: Desafíos y aprendizajes

Purpose: The article presents and discusses some findings derived from a research project about University academic management, and it is focused on the identification of principal clues –even related to subjects and methodology– for the design of training programmes on this task.Design/methodology/approach: The research design adopted a qualitative approach and contemplated the development of in-depth interviews to 71 academic managers at the university who were valued as good in that task, in three Spanish Universities –Universidad de Las Palmas de Gran Canaria (ULP), Universidad de Lleida (UdL) y Universidad de Sevilla (US). Data were analyzed using MAXQDA.11 and their interpretations were contrasted with the opinions obtained in a second round of interviews with 15 of those managers.Findings: Results allows to identify some kind of “vital cycle” in academic managers, inform about their reasons to continue in their managing charges, about their worries related to interpersonal relationships and conflict management, as well as about the recognized need of receiving a specific training for academic management, based on an active an participative methodology which can promote a practical learning.Research limitations/implications: The most important limitations of the study have to do with two unrelated issues. First of them, from a methodological point of view, is related to the limited number of participants. Second of them derives of the changing environment in which management and government model of Spanish is changing. This could probably affect the value and the interest showed by a academics on University management.Practical implications: According to one of the original mains of the study, a training program for academics in university management was already designed and developed.Social implications: The development of training Programs on University management as the one derived from the commented study would represent a contribution for the improvement of Universities’ functioning.Originality/value: Taking into account the limited number of training programs based on empirical evidenced training needs, the relevance of the proposals derived from this study is reinforced.

SmartPort: A Platform for Sensor Data Monitoring in a Seaport Based on FIWARE.

Seaport monitoring and management is a significant research area, in which infrastructure automatically collects big data sets that lead the organization in its multiple activities. Thus, this problem is heavily related to the fields of data acquisition, transfer, storage, big data analysis and information visualization. Las Palmas de Gran Canaria port is a good example of how a seaport generates big data volumes through a network of sensors. They are placed on meteorological stations and maritime buoys, registering environmental parameters. Likewise, the Automatic Identification System (AIS) registers several dynamic parameters about the tracked vessels. However, such an amount of data is useless without a system that enables a meaningful visualization and helps make decisions. In this work, we present SmartPort, a platform that offers a distributed architecture for the collection of the port sensors’ data and a rich Internet application that allows the user to explore the geolocated data. The presented SmartPort tool is a representative, promising and inspiring approach to manage and develop a smart system. It covers a demanding need for big data analysis and visualization utilities for managing complex infrastructures, such as a seaport.

Oil platforms as introduction vector of non-native marine fish species to the Canary Islands waters (central-eastern Atlantic).

Event Abstract Back to Event Oil platforms as introduction vector of non-native marine fish species to the Canary Islands waters (central-eastern Atlantic). Raül Triay-Portella1*, José G. Pajuelo1, José A. González1, José A. Martín1, Raquel Ruiz-Díaz1, José M. Lorenzo1 and Angel Luque1 1 Instituto Universitario de Estudios Ambientales y Recursos Naturales i-UNAT, Departamento de Biología, Universidad de Las Palmas de Gran Canaria, Spain This work documents the introduction of non-native fish species to the Canary Islands (central-eastern Atlantic) through oil rigs. These structures provide artificial hard substrates in places where do not exist naturally. Methodological approaches have included surveys by underwater visual censuses around and under oil platforms and along the docking area of rigs (ground zero). Eleven tropical or subtropical non-native fish species belonging to five families were registered. Paranthias furcifer, Abudefduf hoefleri, Acanthurus bahianus, Acanthurus chirurgus, and Acanthurus coeruleus were first recorded from the Canaries. Other three species not be identified have never been observed in the Canaries. Cephalopholis taeniops, Abudefduf saxatilis, and Acanthurus monroviae had previously recorded. Native areas of these species coincide with the areas of origin and the scale of oil rigs with destination the Port of Las Palmas. The market for oil rigs operating in West Africa and South America has increasingly consolidated the Port of Las Palmas. It is very probable that this heavy overseas traffic was responsible for many of the first records that were attributed to other sources in the past ten years, and according to our data this also could be applied to southern Brazil and the Cape Verdes. For the moment, the number of individuals of the non-native species in marine ecosystems of the Canaries seems to be low, and more investigation is needed for controlling these translocations.
