La influencia de la imagen social de la profesión en las titulaciones universitarias de informática

A diferencia de otras ingenierías, la ingeniería informática tiene una imagen social demasiado condicionada por el concepto difuso de "informático". Esta circunstancia se inscribe en una situación tanto de falta de vocaciones expresadas en la matrícula universitaria como de peculiaridades de las expectativas laborales y de regulación de la profesión. También se refleja en los perfiles de egresado que se incorporan a los planes de estudio de las titulaciones de informática. En este trabajo se presenta un análisis de la imagen social de la profesión así como de algunas implicaciones en el desarrollo y definición de la enseñanza universitaria de las titulaciones relacionadas con la ingeniería informática

Teaching Style in Physical Education and Changes of Daily Physical Activity after One Academic Year in Adolescents: GEOS Study

Increased Moderate-Vigorous physical activity (MVPA) and reduced sedentary time (ST) are key factors for a healthy lifestyle during childhood and adolescence. Studies have suggested that schools may be effective resources to promote healthy habits (Sallis, McKenzie et al. 2012). Therefore, in PE, is important to assess how teachers use strategies and provide students tools to engage in PA with the purpose of reduce the risk of sedentary behavior and contribute to promotion MVPA habits for a healthy lifestyle (Lonsdale, C. et al., 2013). Many factors may be involved in the successful PE class to promote healthy out-school behaviors, as teaching styles (TS), learning styles, learning time, motivation and so on (Mosston, M. 1966). Regarding TS, there is a lack of knowledge about influence of the teaching style (TS) in the promotion of daily MVPA. It was our aim to observe the differences of total daily PA dimensions between two groups of adolescents who were taught during a whole academic year using reproducing (RK) or producing knowledge (PK) TSs.Universidad de Málaga.

Deep Neural Network Model for Evaluating and Achieving the Sustainable Development Goal 16

The decision-making process for attaining Sustainable Development Goals (SDGs) can be enhanced through the use of predictive modelling. The application of predictive tools like deep neural networks (DNN) empowers stakeholders with quality information and promotes open data policy for curbing corruption. The anti-corruption drive is a cardinal component of SDG 16 which is aimed at strengthening state institutions and promoting social justice for the attainment of all 17 SDGs. This study examined the implementation of the SDGs in Nigeria and modelled the 2017 national corruption survey data using a DNN. We experimentally tested the efficacy of DNN optimizers using a standard image dataset from the Modified National Institute of Standards and Technology (MNIST). The outcomes validated our claims that predictive analytics could enhance decision-making through high-level accuracies as posted by the optimizers: Adam 98.2%; Adadelta 98.4%; SGD 94.9%; RMSProp 98.1%; Adagrad 98.1%.publishedVersio

Short-term variability of comet C/2012 S1 (ISON) at 4.8 AU from the Sun

We observed comet C/2012 S1 (ISON) during six nights in February 2013 when it was at 4.8 AU from the sun. At this distance and time the comet was not very active and it was theoretically possible to detect photometric variations likely due to the rotation of the cometary nucleus. The goal of this work is to obtain differential photometry of the comet inner coma using different aperture radii in order to derive a possible rotational period. Large field of view images were obtained with a 4k x 4k CCD at the f/3 0.77m telescope of La Hita Observatory in Spain. Aperture photometry was performed in order to get relative magnitude variation versus time. Using calibrated star fields we also obtained ISON's R-magnitudes versus time. We applied a Lomb-Scargle periodogram analysis to get possible periodicities for the observed brightness variations, directly related with the rotation of the cometary nucleus. The comet light curve obtained is very shallow, with a peak-to-peak amplitude of 0.03 $\pm$ 0.02 mag. A tentative synodic rotational period (single-peaked) of 14.4 $\pm$ 1.2 hours for ISON's nucleus is obtained from our analysis, but there are other possibilities. We studied the possible effect of the seeing variations in the obtained periodicities during the same night, and from night to night. These seeing variations had no effect on the derived periodicity. We discuss and interpret all possible solutions for the rotational period of ISON's nucleus.Comment: 15 pages, 3 Figures, 2 Tables, accepted for publication in A&

Suitability of Using Self-Organizing Neural Networks in Configuring P-System Communications Architectures

Nowadays, it is possible to find out different viable architectures that implements P Systems in a distributed cluster of processors. These proposed architectures have reached a certain compromise between the massively parallelism character of the system and the evolution step times. They are based in the distribution of several membranes in each processor, the use of proxies to control the communication between membranes and mainly, the suitable distribution of the architecture in a balanced tree of processors. For a given P-system and K processors, there exists a great volume of possible distributions of membranes over these. The main disadvantage related with these architectures is focused in the selection of the distribution of membranes that minimizes the external communications between them and maximizes the parallelism grade. In this paper, we suggest the use of Self-Organizing Neural Networks (SONN) with growing capability to help in this selection process for a given P-system

Activity of (2060) Chiron possibly caused by impacts?

The centaur 95P/(2060) Chiron is showing comet-like activity since its discovery, but the mass-loss mechanisms triggering its activity remained unexplained. Although the collision rates in the centaur region are expected to be very low, and impacts are thought not to be responsible for the mass-loss, since the recent indications that Chiron might possess a ring similar to Chariklo's, and assuming that there is debris orbiting around, the impact triggered mass-loss mechanism should not be excluded as a possible cause of its activity. From time series observations collected on Calar Alto Observatory in Spain between 2014 and 2016, we found that the photometric scatter in Chiron's data is larger than a control star's scatter, indicating a possible microactivity, possibly caused by debris falling back to Chiron's surface and lifting small clouds of material. We also present rotational light curves, and measurements of Chiron's absolute magnitudes, that are consistent with the models supporting the presumption that Chiron possesses rings. By co-adding the images acquired in 2015, we have detected a $\sim$5 arcsec long tail, showing a surface brightness of 25.3 mag(V)/arcsec$^{2}$.Comment: Accepted for publication in Monthly Notices of the Royal Astronomical Society (MNRAS) on 2017 December 2

Analysis of Mobile Commerce in the SMEs of the European Union

This paper examines the situation of e-commerce and m-commerce in SMEs in the European Union and analyses if their behaviour in this field is determined by a series of factors, such as the size of the company, the type of business, turnover, etc. which may also influence their needs of specific training for their employees. This study is based on an online survey responded by 674 SMEs from eight different countries in Europe, aimed at providing training assistance to SMEs to support their efforts towards m-commerce. The objective is the analysis of the skills and knowledge to be recommended to employees of SMEs for a better preparation to implement the companies\u27 strategy of m-commerce. Although analysis of results from survey has supported the initial goal of developing training courses for m-commerce which include different economic, legal and technical topics, it has mainly provided very relevant conclusions on the factors which impact the adoption of e-commerce and m-commerce by SMEs

Big Data and Skills Frameworks to Determine Recommended Profiled of Soft Skills for IS Development

Information systems development (ISD) is a social activity where non-cognitive skills (NCS), frequently known as soft skills, are a key factor. Previous efforts to determine the recommended NCS for the ISD professional roles got limited results due to the use of manual procedures, absence of reference frameworks and small size of samples. This work presents a new approach which exploits existing reference models like ESCO, e-CF and NCSF (NCS Framework) as basis to analyse big datasets offered by tools like the ESCO database with thousands of relations between occupations and skills and the Ovate tool with millions of online vacancies. The combination of information from job market with the opinion of experts from ESCO provides a stronger basis for recommended NCS profiles for ISD professional roles, a promising option for an aspect not extensively explored

Regimes of boundary-layer ignition by heat release from a localized energy source

This paper investigates the initiation of a deflagration in a premixed boundary-layer stream by continuous heat deposition from a line energy source placed perpendicular to the flow on the wall surface, a planar flow configuration relevant for small-scale combustion applications, including portable rotary engines. Ignition is investigated in the constant density approximation with a one-step irreversible reaction with large activation energy adopted for the chemistry description. The ratio of the characteristic strain time, given by the inverse of the wall velocity gradient, to the characteristic deflagration residence time defines the relevant controlling Damkhler number D. The time-dependent evolution following the activation of the heat source is obtained by numerical integration of the energy and fuel conservation equations. For sufficiently small values of D, the solution evolves towards a steady flow in which the chemical reaction remains confined to a finite nearsource reactive kernel. This becomes increasingly slender for increasing values of D, corresponding to smaller near-wall velocities, until a critical value D(c)1 is reached at which the confined kernel is replaced by a steady anchored deflagration, assisted by the source heating rate, which develops indefinitely downstream. As the boundary-layer velocity gradient is further decreased, a second critical Damkhler number D-c2 > D-c1 is reached at which the energy deposition results in a flashback deflagration propagating upstream against the incoming flow along the base of the boundary layer. The computations investigate the dependence of D-c1 and D-c2 on the fuel diffusivity and the dependence of D(c 1)on the source heating rate, delineating the boundaries that define the relevant regime diagram for these combustion systems.This work was supported by the Spanish MCINN through projects #CSD2010-00011, ENE2012-33213 and ENE2015-65852-C2-1-R
