Automated analysis of feature models: Quo vadis?

Feature models have been used since the 90's to describe software product lines as a way of reusing common parts in a family of software systems. In 2010, a systematic literature review was published summarizing the advances and settling the basis of the area of Automated Analysis of Feature Models (AAFM). From then on, different studies have applied the AAFM in different domains. In this paper, we provide an overview of the evolution of this field since 2010 by performing a systematic mapping study considering 423 primary sources. We found six different variability facets where the AAFM is being applied that define the tendencies: product configuration and derivation; testing and evolution; reverse engineering; multi-model variability-analysis; variability modelling and variability-intensive systems. We also confirmed that there is a lack of industrial evidence in most of the cases. Finally, we present where and when the papers have been published and who are the authors and institutions that are contributing to the field. We observed that the maturity is proven by the increment in the number of journals published along the years as well as the diversity of conferences and workshops where papers are published. We also suggest some synergies with other areas such as cloud or mobile computing among others that can motivate further research in the future.Ministerio de Economía y Competitividad TIN2015-70560-RJunta de Andalucía TIC-186

Seroprevalence of Theileria equi and Babesia caballi in horses in Spain

Las piroplasmosis equinas son enfermedades parasitarias enzoóticas distribuidas en todo el mundo con una alta incidencia en regiones tropicales y subtropicales. En España, no hay suficientes datos epidemiológicos sobre las piroplasmosis equinas. El objetivo principal del presente estudio fue, por lo tanto, estimar la prevalencia de Theileria equi y Babesia caballi en cinco regiones y obtener información sobre los factores de riesgo. Este estudio se realizó en las regiones central y sudoeste de España, utilizando pruebas de anticuerpos de fluorescencia indirecta (IFAT) en 3,100 muestras de sueros de caballos aparentemente sanos de diferentes edades, razas, colores de pelaje, géneros y ubicaciones geográficas. La seroprevalencia global fue del 52%, consistente en un 44% de seropositivos para T. equi y un 21% para B. caballi. Hubo una asociación significativa entre la edad (p <0,0001), la raza (p <0,004), la ubicación geográfica (p <0,0001) y la seroprevalencia, pero ni el color del pelaje ni el género se asociaron significativamente con la prevalencia. Además, se demostró que la mayoría de las áreas geográficas mostraron una prevalencia de moderada a alta. El valor estadístico j se usó para comparar los resultados obtenidos por el IFAT y el ensayo inmunoabsorbente ligado a enzimas (cELISA) utilizado para analizar algunas muestras (n = 108) y mostró una mayor concordancia para T. equi (j = 0,68) que para B. caballi (j = 0.22). En consecuencia, esto reveló la importancia de desarrollar una técnica apropiada para detectar cada hemoparásito.Equine piroplasmoses are enzootic parasitic diseases distributed worldwide with high incidence in tropical and subtropical regions. In Spain, there is insufficient epidemiological data about equine piroplasmoses. The main aim of the present study was therefore to estimate the prevalence of Theileria equi and Babesia caballi in five regions and obtain information about the risk factors. This study was conducted in the central and south-western regions of Spain, using indirect fluorescence antibody testing (IFAT) in 3,100 sera samples from apparently healthy horses of different ages, breeds, coat colours, genders and geographical locations. The overall seroprevalence was 52%, consisting of 44% seropositive for T. equi and 21% for B. caballi. There was a significant association between age (p < 0.0001), breed (p < 0.004), geographical location (p < 0.0001) and the seroprevalence, but neither the coat colour nor the gender was significantly associated with prevalence. In addition, it was proved that most of the geographic areas showed a moderate to high prevalence. The statistical j value was used to compare the results obtained by the IFAT and the competitive enzyme-linked immunosorbent assay (cELISA) utilised to test some samples (n = 108) and showed a higher concordance for T. equi (j = 0.68) than for B. caballi (j = 0.22). Consequently, this revealed the importance of developing an appropriate technique to detect each haemoparasite.Junta de Extremadura y Fondos FEDER: Ayuda GR15085peerReviewe

Los contenidos curriculares digitalizados: Voces y silencios en el ámbito editorial.

En este artículo se analiza la posición, de algunas de las editoriales presentes en la Comunidad Valenciana, sobre la migración hacia formatos digitales del libro de texto utilizado en centros educativos de niveles no universitarios. Con una metodología mixta se estudian tres dimensiones implicadas en el proceso: la estrategia tecnológica, la pedagógica y la comercial mediante una serie de entrevistas, encuestas, grupos de discusión y análisis de documentos. Entre los resultados alcanzados destaca la gran heterogeneidad de formatos, soportes y marcas; la necesidad de equipos pedagógicos de asesoramiento en las editoriales; la competencia de productos digitales del profesorado y el silencio editorial ante la prospectiva comercial

Extended Floating Car Data System - Experimental Study-

IEEE Intelligent Vehicles Symposium (IV), , 06/06/2011-10/06/2011, Baden-Baden, AlemaniaThis paper presents the results of a set of extensive experiments carried out in daytime and nighttime conditions in real traffic using an enhanced or extended Floating Car Data system (xFCD) that includes a stereo vision sensor for detecting the local traffic ahead. The detection component implies the use of previously monocular approaches developed by our group in combination with new stereo vision algorithms that add robustness to the detection and increase the accuracy of the measurements corresponding to relative distance and speed. Besides the stereo pair of cameras, the vehicle is equipped with a low-cost GPS and an electronic device for CAN Bus interfacing. The xFCD system has been tested in a 198-minutes sequence recorded in real traffic scenarios with different weather and illumination conditions, which represents the main contribution of this paper. The results are promising and demonstrate that the system is ready for being used as a source of traffic state information

"INTERGROWTH21st vs customized fetal growth curves in the assessment of the neonatal nutritional status: a retrospective cohort study of gestational diabetes"

Background Gestational diabetes mellitus is associated with increased incidence of adverse perinatal outcomes including newborns large for gestational age, macrosomia, preeclampsia, polyhydramnios, stillbirth, and neonatal morbidity. Thus, fetal growth should be monitored by ultrasound to assess for fetal overnutrition, and thereby, its clinical consequence, macrosomia. However, it is not clear which reference curve to use to define the limits of normality. Our aim is to determine which method, INTERGROWTH21st or customized curves, better identifies the nutritional status of newborns of diabetic mothers. Methods This retrospective cohort study compared the risk of malnutrition in SGA newborns and the risk of overnutrition in LGA newborns using INTERGROWTH21st and customized birth weight references in gestational diabetes. The nutritional status of newborns was assessed using the ponderal index. Additionally, to determine the ability of both methods in the identification of neonatal malnutrition and overnutrition, we calculate sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios. Results Two hundred thirty-one pregnant women with GDM were included in the study. The rate of SGA indentified by INTERGROWTH21st was 4.7% vs 10.7% identified by the customized curves. The rate of LGA identified by INTERGROWTH21st was 25.6% vs 13.2% identified by the customized method. Newborns identified as SGA by the customized method showed a higher risk of malnutrition than those identified as SGA by INTERGROWTH21st. (RR 4.24 vs 2.5). LGA newborns according to the customized method also showed a higher risk of overnutrition than those classified as LGA according to INTERGROWTH21st. (RR 5.26 vs 3.57). In addition, the positive predictive value of the customized method was superior to that of INTERGROWTH21st in the identification of malnutrition (32% vs 27.27%), severe malnutrition (22.73% vs 20%), overnutrition (51.61% vs 32.20%) and severe overnutrition (28.57% vs 14.89%). Conclusions In pregnant women with DMG, the ability of customized fetal growth curves to identify newborns with alterations in nutritional status appears to exceed that of INTERGROWTH21s
