Is mental health literacy for depression associated with the intention toward preventive actions? A cross-sectional study among university students
2021
Objective Mental Health Literacy (MHL) might play an important role in preventing depression. This study assessed the MHL level for depression of university students and its association with intentions toward preventive actions against depression. Participants: University students (n = 315) were surveyed online. Methods: MHL level and group differences were analyzed using t-tests and one-way ANOVA. To investigate the relation between MHL and the intention for preventive actions against depression, correlation and regression analyses were performed. Results: The mean MHL level of the participants was reasonably high (42.65 of 75 points). MHL levels differed significantly between different gr…
La Promoción y Educación para la Salud desarrollada desde los centros educativos como herramienta clave de las intervenciones de salud
2012
ABSTRACT Promotion and Health Education developed from Schools is one of the key tools of health interventions. Access to children and young people is almost complete because of the obligatory education. In the period of the obligatory people education are more receptive for the learning, being the period of the vital development in which acquire major life habits that are consolidated with the years (physical activity, food, etc.) It also is an area of social intervention that counts with health workers who have high qualifications from the pedagogical point of view. In this context, the main objective of ESP is to develop activities and encourage the students to achieve the highest attain…
On the variations of acoustic absorption peak with particle velocity in micro-perforated panels at high level of excitation.
2010
The acoustic behavior of micro-perforated panels (MPP) is studied theoretically and experimentally at high level of pressure excitation. A model based on Forcheimer's regime of flow velocity in the perforations is proposed. This model is valid at relatively high Reynolds numbers and low Mach numbers. The experimental method consists in measuring the acoustical pressure at three different positions in an impedance tube, the two measurement positions usually considered in an impedance tube and one measurement in the vicinity of the rear surface of the MPP. The impedance tube is equipped with a pressure driver instead of the usual loudspeaker and capable of delivering a high sound pressure lev…
Teachers’ Perceptions of Relationship Enhancement Upon Implementation of the Social Emotional Learning Program in Latvia: Focus Group Study
2017
The goal of this study was to elicit and analyse teachers’ reflections on the benefits of the implementation of the SEL program in Latvia, both in regard to benefits for the students and in regard to benefits for themselves. The school-wide Latvia SEL program was initiated during the 2012–13 academic year and to date has been implemented in 41 Latvian schools. In order to ascertain the teachers’ views on issues of program effectiveness, seven focus groups were organised consisting of teachers who had participated in the SEL program implementation. Thematic analysis of the focus group discussions indicated that the teachers appreciate various benefits of the SEL program, but among the most p…
Adolescentes en conflicto con la Ley.: Una metodología de intervención desde lo local y el acompañamiento social
2012
La intervención social con los adolescentes en conflicto con la ley en medio abierto ha sido escasamente investigada en nuestro país, entre otros motivos por la prioridad de lo judicial, la complejidad del objeto de investigación, la escasa importancia frente al medio cerrado, etc. Tras nuestra experiencia en el ámbito de la justicia juvenil y más específicamente, en la intervención con adolescentes en conflicto con la ley en medio abierto, exponemos un modelo de intervención desde la lógica de lo local y el acompañamiento social, como propuesta de una metodología de intervención válida para el trabajo con adolescentes en conflicto con la ley en medio abierto. Social intervention with teena…
A NEW SYMMETRIC AND POSITIVE DEFINITE BOUNDARY ELEMENT FORMULATION FOR LATERAL VIBRATIONS OF PLATES
1997
Abstract A new symmetric and positive definite boundary element method in the time domain is presented for the dynamic analysis of thin elastic plates. The governing equations of the problem are obtained from a variational principle in which a hybrid modified functional is employed. The functional is expressed in terms of the domain and boundary basic variables in plate bending, assumed to be independent of each other. In the discretized model the boundary variables are expressed by nodal values, whereas the internal displacement field is modelled by a superposition of static fundamental solutions. The equations of motion are deduced from the functional stationarity conditions and they cons…
Dynamic stability of plane elastic frames
1982
Abstract The stability of plane elastic frames subjected to a vertical foundation motion of the stationary, ergodic type is investigated. The equations of motion are obtained in modal co-ordinates, with account taken of many modes of vibration. The problem is subsequently reduced to the study of only the first mode of vibration. By considering a particular case, the stability domains are sketched as functions of the variation of the rigidities of the beam-column connecting joints and as functions of the number of stories.
Dropping out of school as a meaningful action for adolescents with social, emotional and behavioural difficulties
2013
This study examines and discusses dropping out of school related to adolescents with social, emotional and behavioural difficulties (SEBD). It is based on in-depth interviews of 10 adolescents between the ages of 16 and 20, three girls and two boys with internalised problems, and two girls and three boys with extroverted behavioural problems. Given this group of students' challenges at school, the aim of this paper is to explore the narratives of this adolescent group as they relate to the significance they attach to their dropout behaviour. An additional objective is to draw attention to what these findings are likely to mean for implementing preventive practices in school. Results show th…
VLBI detection of the HST-1 feature in the M87 jet at 2 cm
2010
A bright feature 80 pc away from the core in the powerful jet of M87 shows highly unusual properties. Earlier radio, optical and X-ray observations have shown that this feature, labeled HST-1, is superluminal, and is possibly connected with the TeV flare detected by HESS in 2005. It has been claimed that this feature might have a blazar nature, due to these properties. To examine the possible blazar-like nature of HST-1, we analyzed lambda 2 cm VLBA archival data from dedicated full-track observations and the 2 cm survey/MOJAVE VLBI monitoring programs obtained between 2000 and 2009. Applying VLBI wide-field imaging techniques, the HST-1 region was imaged at milliarcsecond resolution. Here …
Community dimensions and emotions in the era of COVID-19
2021
Abstract Following an ecological perspective, reactions to a disaster—such as the COVID‐19 pandemic—should be analysed in the interdependence between individual and community dimensions. The present study aims to analyse individual emotional dimensions (anxiety, joy, fear or depressive feelings) and their community dimensions (connectedness, emotional sharing and solidarity) with a longitudinal approach among university students from Italian universities. Participants were 746 university students at t1 (during the lockdown) and 361 at t2 (after the lockdown) recruited in six Italian universities from different areas of Italy. Comparing emotional dimensions in the two times, t2 is characteri…
