An analysis of different resources and programmes supporting at-risk families in Spain
The purpose of this research was to present an overview of the existing
family support resources in Spain for at-risk families. We analysed 64
family support services from 16 agencies belong to 11 regions of Spain.
In a second phase, 20 positive parenting programmes were analysed in
depth to ascertain the extent to which they met evidence-based
programme quality criteria. Our results suggest that services for at-risk
families are delivered by public, local and social agencies. Most
interventions were psycho-educational and aimed at parental training.
The analysis of the positive parenting programmes
’
quality showed both
strengths and weaknesses. Most programmes relied on a previous needs
analysis and interventions were, to some extent, outlined in a manual.
Nevertheless, few programmes have been evaluated according to
evidence-based programme criteria. In light of these results, we discuss
several practical implications for services and family support policies
aimed at at-risk families.Ministerio de Economía y Competitividad de España EDU2013-41441-
Effects of a mixed reality headset on the delay of visually evoked potentials
Virtual and mixed reality (VR, MR) technologies offer a powerful solution for
on-the-ground flight training curricula. While these technologies offer safer
and cheaper instructional programs, it is still unclear how they impact
neuronal brain dynamics. Indeed, MR simulations engage students in a strange
mix of incongruous visual, somatosensory and vestibular sensory input.
Characterizing brain dynamics during MR simulation is important for
understanding cognitive processes during virtual flight training. To this end,
we studies the delays introduced in the neuronal stream from the retina to the
visual cortex when presented with visual stimuli using a Varjo-XR3 headset. We
recorded cortical visual evoked potentials (VEPs) from 6 subjects under two
conditions. First, we recorded normal VEPs triggered by short flashes. Second,
we recorded VEPs triggered by an internal image of the flashes produced by the
Varjo-XR3 headset. All subjects had used the headset before and were familiar
with immersive experiences. Our results show mixed-reality stimulation imposes
a small, but consistent, 4 [ms] processing delay in the N2-VEP component during
MR stimulation as compared to direct stimulation. Also we found that VEP
amplitudes during MR stimulation were also decreased. These results suggest
that visual cognition during mixed-reality training is delayed, not only by the
unavoidalbe hardware/software processing delays of the headset and the attached
computer, but also by an extra biological delay induced by the headset's
limited visual display in terms of the image intensity and contrast. As flight
training is a demanding task, this study measures visual signal latency to
better understand how MR affects the sensation of immersion
Multi-scale Entropy Evaluates the Proarrhythmic Condition of Persistent Atrial Fibrillation Patients Predicting Early Failure of Electrical Cardioversion
[EN] Atrial fibrillation (AF) is nowadays the most common cardiac arrhythmia, being associated with an increase in cardiovascular mortality and morbidity. When AF lasts for more than seven days, it is classified as persistent AF and external interventions are required for its termination. A well-established alternative for that purpose is electrical cardioversion (ECV). While ECV is able to initially restore sinus rhythm (SR) in more than 90% of patients, rates of AF recurrence as high as 20-30% have been found after only a few weeks of follow-up. Hence, new methods for evaluating the proarrhythmic condition of a patient before the intervention can serve as efficient predictors about the high risk of early failure of ECV, thus facilitating optimal management of AF patients. Among the wide variety of predictors that have been proposed to date, those based on estimating organization of the fibrillatory (f-) waves from the surface electrocardiogram (ECG) have reported very promising results. However, the existing methods are based on traditional entropy measures, which only assess a single time scale and often are unable to fully characterize the dynamics generated by highly complex systems, such as the heart during AF. The present work then explores whether a multi-scale entropy (MSE) analysis of thef-waves may provide early prediction of AF recurrence after ECV. In addition to the common MSE, two improved versions have also been analyzed, composite MSE (CMSE) and refined MSE (RMSE). When analyzing 70 patients under ECV, of which 31 maintained SR and 39 relapsed to AF after a four week follow-up, the three methods provided similar performance. However, RMSE reported a slightly better discriminant ability of 86%, thus improving the other multi-scale-based outcomes by 3-9% and other previously proposed predictors of ECV by 15-30%. This outcome suggests that investigation of dynamics at large time scales yields novel insights about the underlying complex processes generatingf-waves, which could provide individual proarrhythmic condition estimation, thus improving preoperative predictions of ECV early failure.This research has been supported by grants DPI2007-83952-C3 from MINECO/AEI/FEDER EU, SBPLY/17/180501000411 from Junta de Comunidades de Castilla la Mancha and AICO/2019/036 from Generalitat Valenciana.Cirugeda Roldan, EM.; Calero, S.; Hidalgo, VM.; Enero, J.; Rieta, JJ.; Alcaraz, R.

The effectiveness of a child day-care program in child welfare services
Family support initiatives aimed at guaranteeing children's rights and preserving the family are undergoing
extensive diversification, to meet the specific needs and strengths of families. Child day-care initiatives constitute
a novel approach in child welfare services, as a way to complement family service for at-risk families.
They are delivered in a child-group format and follow a psycho-educational methodology. This study analyzed
the impact of a novel child day-care program on children's quality of life, adjustment and development, and
explored the moderating role of different child and family dimensions on the program's impact. For this purpose,
we followed a pretest-posttest evaluation with a control group (N=83). The results showed improvements in
different facets of children's quality of life, as well as a positive impact in other adjustment and developmental
dimensions, such as social skills, internalizing problems, and intelligence. Interaction effects were found between
internalizing problems and children's sex, and between academic competence and family risk level. In conclusion,

El presente documento tiene como objeto utilizar el aula invertida o flipped classroom como una estrategia para mejorar los aprendizajes en los estudiantes, dando lugar a un auto aprendizaje y al desarrollo de capacidades de investigación, observación, reflexión, análisis, interpretación, síntesis en la adquisición de sus propios conocimientos. Por otro lado el docente se convierte en planificador de los materiales que investiga el estudiante en casa y facilitador en el aula, donde se abren foros y discusiones para aclarar las inquietudes y dudas de lo aprendido. La metodología para determinar si en la carrera de Ingeniería Industrial en Procesos de Automatización de la Universidad Técnica de Ambato se aplica el auto aprendizaje, se realizó una encuesta a profesores y estudiantes, observándose el desconocimiento de la estrategia del aula invertida, por lo tanto se considera que es necesario diseñar y planificar una clase utilizando esta estrategia, la misma que se convertirá en un sistema de acciones centrado en los interés de los estudiantes y el empoderamiento de su conocimiento.PALABRAS CLAVE: Aula invertida; didáctica; enseñanza; aprendizaje.DIDACTICS OF THE INVERTED CLASSROOM AND PHYSICS TEACHING AT THE TECHNICAL UNIVERSITY OF AMBATOABSTRACTThe purpose of this document is to use the inverted classroom or flipped classroom as a strategy to improve student learning, leading to self-learning and the development of research, observation, reflection, analysis, and interpretation and synthesis skills in knowledge self-acquisition. On the other hand the teacher becomes a planner of the materials researched by the student at home and facilitator in the classroom, where forums and discussions are opened to clarify the concerns and doubts of what was learned. The methodology to determine if in the Industrial Engineering course in Automation Processes of the Technical University of Ambato the self-learning is applied, a survey was made to professors and students, observing the ignorance of the inverted classroom strategy, therefore considers that it is necessary to design and plan a class using this strategy, which will become a system of actions focused on the interests of students and the empowerment of their knowledge.KEYWORDS: Flipped classroom; didactics; teaching; learning
Estudio Comparativo De Las Metodologías De Análisis Forense Informático Para La Examinación De Datos En Medios Digitales
The aim of this research is to compare the different standards and methodologies of computer forensic analysis used in the examination of data in digital media. The research was developed based on the scientific method, and a standard and two analysis methodologies were specifically used, which were applied to ten researchers. The analysis variables were based on the feasibility of use and on the time of extracting information from the computer. Among the comparison results of the different methodologies analyzed, it was determined that for the Methodology UNE 71506: 2013, 60% of the researchers used it due to the feasibility of use because it is made up of a robust process (contains the most detailed steps of computer forensics). Reliable and applicable in any field necessarily supervised by specialists working in the area, compared to the National Institute of Standards and Technology that selected 30%, Integrated Digital Investigation Process 10%. Regarding the time of analysis in the examination of digital media with different methodologies (Case study: Extraction of a file of 100 Mb, of a hard disk of 20 Gb in off mode. It is revealed that in the UNE 71506: 2013 it took less than 1 hour compared to the National Institute of Standards and Technology, which took between 1 and less than 2 hours, the Integrated Digital Investigation Process, which lasted longer than 3 hours. In addition, with the use of the Methodology UNE 71506: 2013, it was possible to have greater feasibility in the examination of digital media, since it is composed of four stages such as the preservation, acquisition, analysis and presentation of information results
Análisis Comparativo De Herramientas Forenses Informáticas Para La Realización De Peritajes En Medios Digitales
This paper focuses on making a comparison of the different computer forensic tools used in the performance of data surveys in digital media. The research was developed based on the method of weighting by criteria (scientific and descriptive study). In this study, specifically four computer forensic tools were used and evaluated by six criteria for the selection of them, and they were chosen based on ISO 9126:1998. Based on the comparison, the results of the four computer forensic tools were analyzed. It was determined that for the different criteria (Case study: Clone of 500 Gb hard disk in off mode), the HD Clone and XWay Forensics tools obtained 84.62% of acceptability, compared to Norton Ghost that obtained a contribution of 69.23% and the tool EnCase with a score of 58.46% to obtain the cloning of the disks. In addition, with the use of ISO 9126: 1998, greater portability, reliability of the results, acquisition cost of the tool, ease of use and application, greater operational capacity and support for the tool was achieved in the cloning of digital media. This is attributed to the fact that it is composed of six evaluation criteria as mentioned above
Incidencia del Software Educativo en el proceso de enseñanza-aprendizaje de la Matemática
The teaching-learning process of Mathematics is complex due to its level of abstraction, making it a challenge for the strategies and didactic resources used by teachers, since the goal is to achieve an adequate academic level in the students, for this it results evident the use of technology since nowadays they play a leading role in society, for that reason the research had as intent the improvement of the learning of the rational numbers of the students of the Educational Unit "Benito Juárez", through the technological resource didactic based on the application of a Mathematical Software. The design of the research is quasi-experimental, correlational-explanatory, the "t" test for independent samples was used to contrast the hypothesis. For data collection, the survey and a test were used that were validated to ensure reliability, the data were analyzed using descriptive statistics. The important results were: (a) better academic performance of the sayers of the experimental group as opposed to the group that did not use it, (b) acceptance and motivation by the didactic resource (c) put into practice their cognitive and motor skills. Therefore, the research provided evidence to use the Mathematical Software as a suitable didactic technological resource for a meaningful learning of Mathematics
Diagnosing hospital bacteraemia in the framework of predictive, preventive and personalised medicine using electronic health records and machine learning classifiers
Background
The bacteraemia prediction is relevant because sepsis is one of the most important causes of morbidity and mortality. Bacteraemia prognosis primarily depends on a rapid diagnosis. The bacteraemia prediction would shorten up to 6 days the diagnosis, and, in conjunction with individual patient variables, should be considered to start the early administration of personalised antibiotic treatment and medical services, the election of specific diagnostic techniques and the determination of additional treatments, such as surgery, that would prevent subsequent complications. Machine learning techniques could help physicians make these informed decisions by predicting bacteraemia using the data already available in electronic hospital records.
Objective
This study presents the application of machine learning techniques to these records to predict the blood culture’s outcome, which would reduce the lag in starting a personalised antibiotic treatment and the medical costs associated with erroneous treatments due to conservative assumptions about blood culture outcomes.
Methods
Six supervised classifiers were created using three machine learning techniques, Support Vector Machine, Random Forest and K-Nearest Neighbours, on the electronic health records of hospital patients. The best approach to handle missing data was chosen and, for each machine learning technique, two classification models were created: the first uses the features known at the time of blood extraction, whereas the second uses four extra features revealed during the blood culture.
Results
The six classifiers were trained and tested using a dataset of 4357 patients with 117 features per patient. The models obtain predictions that, for the best case, are up to a state-of-the-art accuracy of 85.9%, a sensitivity of 87.4% and an AUC of 0.93.
Conclusions
Our results provide cutting-edge metrics of interest in predictive medical models with values that exceed the medical practice threshold and previous results in the literature using classical modelling techniques in specific types of bacteraemia. Additionally, the consistency of results is reasserted because the three classifiers’ importance ranking shows similar features that coincide with those that physicians use in their manual heuristics. Therefore, the efficacy of these machine learning techniques confirms their viability to assist in the aims of predictive and personalised medicine once the disease presents bacteraemia-compatible symptoms and to assist in improving the healthcare economy
