    Description: Sustainability, Vol. 10, Pages 2805: Multidimensional Self-Concept in Elementary Education: Sport Practice and Gender Sustainability doi: 10.3390/su10082805 Authors: Diana Amado-Alonso Santiago Mendo-Lázaro Benito León-del-Barco Mario Mirabel-Alviz Damián Iglesias-Gallego Background: The purpose of this study was to analyse the relation between the number of hours of organized sports practice and self-concept, considered from a multidimensional approach (physical, emotional, academic, social and family self-concept). The relation between these variables as a function of gender was also investigated. Methods: We used a sample of 840 students from fifth and sixth grade of Elementary Education (494 boys and 346 girls), aged 9 to 12 years, from Spain. To assess the students’ self-concept, we used the AF-5 Self-Concept Form 5 questionnaire. Results: The results show that children who practice organized sport, present a better physical self-concept (0 h a day [h/d]: M = 5.20, SD = 1.82; 1 h/d: M = 5.90, SD = 1.82; 2 h/d: M = 5.99, SD = 1.56; 3 h/d: M = 6.00, SD = 1.42). Boys present a higher emotional self-concept than girls (p < 0.05). Moreover, children’s sports practice is beneficial for the academic and family self-concept but in the case of girls, a high number of hours of daily practice may be decreasing these potential benefits. Conclusions: The findings suggest that organized sports practice could have a positive effect on self-concept. We underline the importance of encourage children to practice sport and paying particular attention to gender differences in the development of the emotional self-concept during elementary education.

    Description: Sensors, Vol. 18, Pages 1132: Real-Time Seismic Data from the Bottom Sea Sensors doi: 10.3390/s18041132 Authors: Xavier Roset Enric Trullols Carola Artero-Delgado Joana Prat Joaquin Del Río Immaculada Massana Montserrat Carbonell Jaime Barco de la Torre Daniel Toma An anchored marine seismometer, acquiring real-time seismic data, has been built and tested. The system consists of an underwater seismometer, a surface buoy, and a mooring line that connects them. Inductive communication through the mooring line provides an inexpensive, reliable, and flexible solution. Prior to the deployment the dynamics of the system have been simulated numerically in order to find optimal materials, cables, buoys, and connections under critical marine conditions. The seismometer used is a high sensitivity triaxial broadband geophone able to measure low vibrational signals produced by the underwater seismic events. The power to operate the surface buoy is provided by solar panels. Additional batteries are needed for the underwater unit. In this paper we also present the first results and an earthquake detection of a prototype system that demonstrates the feasibility of this concept. The seismometer transmits continuous data at a rate of 1000 bps to a controller equipped with a radio link in the surface buoy. A GPS receiver on the surface buoy has been configured to perform accurate timestamps on the seismic data, which makes it possible to integrate the seismic data from these marine seismometers into the existing seismic network.

    Description: IJERPH, Vol. 15, Pages 1314: Impact of the Familiar Environment in 11–14-Year-Old Minors’ Mental Health International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071314 Authors: Benito León-del-Barco Fernando Fajardo-Bullón Santiago Mendo-Lázaro Irina Rasskin-Gutman Damián Iglesias-Gallego The analysis of the mental health in children under 14 years has become a research topic of global interest where the family can be a key factor for protection or risk against mental health problems. With this work, we intend to determine, employing binary logistic regression analysis, whether parental acceptance-rejection perceived by boys and girls can predict their mental health. Seven hundred sixty-two students participated, the average age was 12.23 years; 53.8% (n = 410) girls and 46.2% (n = 352) boys. We have used the Strengths and Difficulties Questionnaire (SDQ), self-reported version and the Affection Scale children version (EA-H) for parental acceptance-rejection to assess mental health. The odds ratio (OR) of the logistic models reports that there is a greater probability of having mental health problems in boys and girls when they perceive that they are highly criticized and rejected by their parents. With our work, we highlight the importance of the environment and family affection on mental health. The perception of the children about the rejection, aversion, and criticism of their parents constitutes a risk factor in the manifestation of mental health problems.
