A method for supporting heterogeneous-group formation through heuristics and visualization

Group formation is a key issue in e-learning environments that make use of collaborative work to enhance student performance. While there are many ways to arrange students to work in cooperative groups, recent works have shown that learning styles offer good opportunities to organize students. Particularly, it seems the case that regarding learning styles, heterogeneous groups tend to perform better than groups formed by students with similar characteristics. This work addresses the issue of supporting the authors’ task of forming effective learner groups to improve student and group performance. This support is provided through a supervised method which, backed by a visualization tool, is able to produce groups with a good level of heterogeneity. Moreover, this method is not time-consuming for teachers.This project has been funded by the Spanish Ministry of Science and Education (TIN2007-64718) and Comunidad Autonoma de Madrid (S2009/TIC-1650)

An adaptive hierarchical questionnaire based on the Index of Learning Styles

Proceedings of the Sixth International Workshop on Authoring of Adaptive and Adaptable HypermediaOne of the main concerns when providing learning style adaptation in Adaptive Educational Hypermedia Systems is the number of questions the students have to answer. With respect to learning styles, it is possible to decrease the number of versions taking into account the general tendency of the student and not the specific score obtained in each dimension. In this paper we present a new approach to reduce the number of questions of Index of Learning Styles (ILS) questionnaire based on Felder-Silverman’s Learning Style Model (FSLSM). The results obtained in a case study with 330 students are very promising. It was possible to predict students’ learning styles with high accuracy and only a few questions.This work is supported by the Spanish Ministry of Education and Science, TIN2007-6471

The impact of learning styles on student grouping for collaborative learning: a case study

The final publication is available at Springer via http://dx.doi.org/10.1007/s11257-006-9012-7Learning style models constitute a valuable tool for improving individual learning by the use of adaptation techniques based on them. In this paper, we present how the benefit of considering learning styles with adaptation purposes, as part of the user model, can be extended to the context of collaborative learning as a key feature for group formation. We explore the effects that the combination of students with different learning styles in specific groups may have in the final results of the tasks accomplished by them collaboratively. With this aim, a case study with 166 students of computer science has been carried out, from which conclusions are drawn. We also describe how an existing web-based system can take advantage of learning style information in order to form more productive groups. Our ongoing work concerning the automatic extraction of grouping rules starting from data about previous interactions within the system is also outlined. Finally, we present our challenges, related to the continuous improvement of collaboration by the use and dynamic modification of automatic grouping rules.This project has been funded by the Spanish Ministry of Science and Education, TIN2004-03140

Green bottle flies (Calliphoridae, Luciliinae) of Ecuador: geographic distribution, checklist and DNA barcodes

Green bottle flies (Diptera, Calliphoridae, Luciliinae) comprise a diverse and cosmopolitan taxon, known from at least 1,500 species. They have become crucial elements in forensic investigations, as they spend part of their life cycle in decaying remains. Here, we review the distribution of eleven Luciliinae species in Ecuador: the monotypic Blepharicnema and ten Lucilia species. We identified specimens using morphological characters. Additionally, we DNA barcoded 43 specimens from three species using 658bp segments of the standard Cytochrome Oxidase I (COI) mitochondrial gen. Molecular and morphological identifications presented high correspondence, suggesting COI barcodes are an efficient tool for the identification of these three green bottle flies species. Geographical records are biased towards the northern Andean region, particularly near to large urban settlements. We remark the value to applied forensic research of continuous sampling of necrophagous flies under a variety of habitats and crime conditions.Fil: Moreno Coellar, Emilia.

La coexistencia de Desmodus rotundus con la población humana en San Luis Potosí, México

Desmodus rotundus is a transmitter of zoonotic and emerging diseases to humans and livestock, such as rabies. Most infectious diseases are spatially limited by the presence of the transmitter, whose abundance and survival are influenced by environmental conditions and the presence of food sources. A tool that facilitates its study is the use of Geographic Information Systems. The objective of this study was to analyze the interaction of populations of hematophagous bats and humans, through the development of a probable model of dispersal of D. rotundus based on known shelters and different environmental variables, in addition to analyzing the relationship between shelters identified for three years and their proximity to human settlements, as a process of coexistence. The study was conducted in the state of San Luis Potosí from 2014 to 2016. A total of 180 shelters of D. rotundus distributed towards the Huasteca region were identified, 80 % of these were built by man and 57 % were inhabited. A buffer of 5 km around from the location of each shelter was calculated, finding inside a total of 976 rural communities and 15 cities, with 337,836 inhabitants. The average distance from shelters to the first human settlement was 518.65 ± 11.33 m. It is necessary to continue studying the association between urbanization and the emergence of zoonoses, through the understanding of the interactions between wild animals-livestock-humans.Desmodus rotundus es transmisor de enfermedades zoonóticas y emergentes a los humanos y al ganado, como el caso de la rabia. La mayoría de las enfermedades infecciosas están limitadas espacialmente por la presencia del transmisor, cuya abundancia y supervivencia son influenciadas por las condiciones ambientales y la presencia de fuentes de alimentación. Una herramienta que facilita su estudio es el uso de los Sistemas de Información Geográfica. El objetivo de este estudio fue analizar la interacción de las poblaciones de murciélagos hematófagos y humanos, a través de la elaboración de un modelo probable de dispersión del D. rotundus basado en refugios conocidos y diferentes variables medioambientales, además de analizar la relación entre refugios identificados durante tres años y su cercanía con asentamientos humanos, como un proceso de coexistencia. El estudio se llevó a cabo en el estado de San Luis Potosí del año 2014 al 2016. Se identificaron un total de 180 refugios de D. rotundus distribuidos hacia la zona de la Huasteca, el 80 % de éstos fueron construidos por el hombre y el 57 % se encontraron habitados. Se calculó un buffer de 5 km a la redonda a partir de la ubicación de cada refugio, encontrando en su interior un total de 976 comunidades rurales y 15 ciudades, con 337,836 habitantes. La distancia media de los refugios hasta el primer asentamiento humano fue de 518.65 ± 11.33 m. Es necesario continuar estudiando la asociación entre la urbanización y el surgimiento de zoonosis, a través del entendimiento de las interacciones entre animales silvestres-ganadería - humanos

Authoring and dynamic generation of adaptive e-courses

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-540-27834-4_93Proceedings of the 4th International Conference, ICWE 2004, Munich, Germany, July 26-30, 2004.Adaptive hypermedia constitutes a pretty rich resource for developing web-based courses. With the aim of dynamically generating adaptive e-courses, we have developed the TANGOW system which, starting from the course components and their adaptation capabilities (specified independently and out of the adaptation engine), generates different courses for students with different profiles, supporting several adaptation strategies. An integral part of any adaptive hypermedia system is the set of authoring tools to specify the course components and their adaptation capabilities. Without adequate tool support, authors may feel that it is “not worth the effort” to add adaptation to their courses. However, the development of this type of tools is not an easy task. The main goal of our authoring and visualization tools is to provide a simple interface to create such courses. This demo would demonstrate i) the dynamic generation of tailored e-courses that include individual and collaborative activities and ii) the use of authoring tools for the creation of such courses

Adquisición De Datos De Magnitudes En Un Sistema Oleohidráulico Para Su Control Y Monitoreo En Un Laboratorio Remoto De Instrumentación Virtual De Código Abierto

The present research analyzes the state of the art of remote laboratories and their use in teaching and industry. In addition, the aim of this study is to develop a test bench to control and maintain, in optimal conditions, the operating parameters of a hydraulic oil system through an open source virtual platform. This equipment will analyze the behavior of an external gear pump which will enable us to make comparisons of mathematical models to predict the flow rate and compare it with that obtained in real time through the test bench. The analysis starts with a theoretical revision that is used for defining the variables to be controlled in the test bench. It is also used to propose a methodology that allows reaching the objectives raised

Blood DNA methylation signature of diet quality, and association with cardiometabolic traits

BACKGROUND: Diet quality might influence cardiometabolic health through epigenetic changes, but this has been little investigated in adults. Our aim was to identify Cytosine-phosphate-Guanine (CpG) dinucleotides associated with diet quality by conducting an epigenome-wide association study (EWAS) based on blood DNA methylation (DNAm), and to assess how diet-related CpGs associate with inherited susceptibility to cardiometabolic traits: body mass index (BMI), systolic blood pressure (SBP), triglycerides, type 2 diabetes (T2D) and coronary heart disease (CHD). METHODS: Meta-EWAS including 5,274 participants in four cohorts from Spain, the US and the UK. We derived three dietary scores (exposures) to measure adherence to a Mediterranean diet (MMDS), to a healthy plant-based diet (HPDI) and to the Dietary Approaches to Stop Hypertension (DASH). Blood DNAm (outcome) was assessed with the Infinium arrays Human Methylation 450 K BeadChip and MethylationEPIC BeadChip. For each diet score, we performed linear EWAS adjusted for age, sex, blood cells, smoking and technical variables, and BMI in a second set of models. We also conducted Mendelian randomization analyses to assess the potential causal relationship between diet-related CpGs and cardiometabolic traits. RESULTS: We found 18 differentially methylated CpGs associated with dietary scores (p-value < 1.08 × 10-7; Bonferroni correction), of which 12 were previously associated with cardiometabolic traits. Enrichment analysis revealed overrepresentation of diet-associated genes in pathways involved in inflammation and cardiovascular disease. Mendelian randomization analyses suggested that genetically determined methylation levels corresponding to lower diet quality at cg02079413 (SNORA54), cg02107842 (MAST4), and cg23761815 (SLC29A3) were causally associated with higher BMI, and at cg05399785 (WDR8) with greater SBP; and methylation levels associated with higher diet quality at cg00711496 (PRMT1) with lower BMI, T2D risk and CHD risk, and at cg0557921 (AHRR) with lower CHD risk. CONCLUSIONS: Diet quality in adults was related to differential methylation in blood at 18 CpGs, some of which related to cardiometabolic health.Availability: The R code for the analysis is available in the following Github repository: https://github.com/jorgedb98/B64_DIAMETR.git
