School achievement gaps and school failure are problematic issues in Latin America, and are mainly explained by the socio-economic status (SES) of the students. What schools can do to improve school achievement and reduce school failure is a critical issue, both for school management and teacher training. In this study, we present the association of individual and school-related socio-emotional variables with school achievement and performance, controlling for the effects of SES. A probabilistic sample of 4,964 students, drawn from 191 schools enrolled in year 10 in urban areas of Chile, answered questionnaires assessing subjective wellbeing, social wellbeing in school, school climate, school social wellbeing and students’ perceptions of teachers’ wellbeing. Using structural equation modeling, and controlling for SES, we modeled subjective wellbeing as a mediator of the relationship between school-related variables, such as school climate and perception of teacher’s wellbeing, and (a) school achievement, and (b) school performance. School achievement was computed as a product of (a) the probability of passing the school year, and (b) the percentage of yearly attendance at school. Data on school achievement was drawn from administrative registries from the Chilean Ministry of Education. School performance was computed as the estimated grade point average (GPA) at the end of the school year, based on the students’ previous 5-year GPAs, and was also obtained through administrative data of the last 5 years. Findings reveal the mediating role of subjective wellbeing in the relationship between school-related evaluations (students’ social wellbeing at school, their perception of teachers’ wellbeing and school climate) and school achievement. For school achievement, two variables were mediated (students’ social wellbeing at school and school climate). However, for school performance, no significant mediations were found. We conclude that, on the one hand, after controlling for SES, students’ individual subjective wellbeing is associated with their achievement and performance in school. We discuss the importance of improving school experiences that may protect and promote students’ subjective experience and school achievement and performance, and reduce the probability of school failure and dropout.

La violencia entre pares afecta negativamente la salud mental de los estudiantes. La literatura señala que la satisfacción con la vida es uno de los factores que puede verse mayormente afectado. No obstante, pueden existir factores que atenúen estos efectos negativos. La presente investigación indagó en la influencia que tiene el apoyo de profesores y pares en la escuela sobre la satisfacción con la vida en estudiantes que reportan agresiones de sus pares. El estudio censal incluyó a 5.527 estudiantes de 4° a 8° grado de educación básica de 44 establecimientos municipales de una comuna de la Región de Valparaíso, Chile. Usando cuestionarios autoaplicados de la encuesta "La Convivencia en mi Escuela", cuyos datos se analizaron usando modelos de ecuaciones estructurales, se encontró que el apoyo social de los profesores tiene un efecto más importante que el de los pares como mediador en la relación inversa entre victimización entre pares y satisfacción con la vida de los estudiantes. Estos hallazgos son discutidos respecto del papel mediador de los profesores en la victimización entre pares.Palabras clave: victimización, satisfacción vital, apoyo social, bienestar, bullying Violence among peers has a negative effect on students' mental health. The literature indicates that life satisfaction is one of the factors on which peer violence could have a major effect. Nevertheless, some factors may attenuate this negative impact. This study analyzed the influence of teacher and peer support on the relation between students' peer victimization and life satisfaction. The sample included 5,527 students from grades 4 through 8 attending municipal schools in one district of the Region of Valparaíso, Chile. Using self-report questionnaires taken from the survey "Coexistence in my School", whose data was analyzed with structural equation modeling, it was observed that teacher social support has a greater effect than peer social support as a mediator in the inverse relationship between students' peer victimization and life satisfaction. These findings are discussed in terms of the mediating role of teachers in reducing the effects of peer victimization.

Introduction: Massive tear of the rotator cuff (DMMR) is a degenerative clinical condition, which corresponds to a 5 cm rupture, or one that compromises two or more tendons of the rotator cuff (MR), generating loss of functionality and disabling pain.Objective: To describe changes in pain and shoulder function following a 6-week program of lateral-imaging and motion imaging therapy and selective glenohumeral activation exercises in subjects with massive rotator cuff tears.Methods: This study is a descriptive research and design of a series of cases, with a sample of 50 participants with diagnosis of rotator cuff mastication. Patients underwent a glenohumeral selective exercise program plus laterality and motion imaging therapy for 6 weeks. The variables of function, pain, abduction ROM and shoulder flexion were measured at sixth week and sixth month of evolution.Results: There were significant differences in pain intensity, shoulder function, AROM flexion and shoulder abduction AROM, after the intervention (p > 0.05). Statistically significant differences were found for all outcome measures between the intervention and the sixth follow-up month (p < 0.05). Only the

The paper describes the evaluation studies of a learning game for older adults using a multicultural European sample. The goal of the evaluation was to explore the acquisition of knowledge as a result of game play, the acceptance of two different game interaction systems by the seniors, their experiences while playing the game, and the accessibility of the game's user interface. Several qualitative and quantitative research methods were combined among older adults in the Netherlands, Spain and Greece. The tests revealed that (i) the accessibility of the game menus and interaction devices was high, (ii) the player experience in digital game play with a TV remote control and 3D sensor were mostly positive, and (iii) the older adults reported that they experienced learning. Overall, it can be concluded that the goals were met, offering a similar accessibility and player experience between the three different countries, and to provide a learning experience for older Europeans.
