Warp evidences in precessing galactic bar models

Most galaxies have a warped shape when they are seen from an edge-on point of view. The reason for this curious form is not completely known so far and in this work we apply dynamical system tools to contribute to its explanation. Starting from a simple, but realistic, model formed by a bar and a disc, we study the effect produced by a small misalignment between the angular momentum of the system and its angular velocity. To this end, a precession model is developed and considered, assuming that the bar behaves like a rigid body. After checking that the periodic orbits inside the bar keep being the skeleton of the inner system, even after inflicting a precession to the potential, we compute the invariant manifolds of the unstable periodic orbits departing from the equilibrium points at the ends of the bar to get evidences of their warped shapes. As it is well known, the invariant manifolds associated with these periodic orbits drive the arms and rings of barred galaxies and constitute the skeleton of these building blocks. Looking at them from a side-on viewpoint, we find that these manifolds present warped shapes as those recognized in observations. Lastly, test particle simulations have been performed to determine how the stars are affected by the applied precession, confirming this way the theoretical results obtained.Comment: 14 pages, 21 figures, Accepted for publication in A&A (15th Jan 2016

Dejar la profesión docente: análisis del papel del apoyo social, el engagement y la inteligencia emocional en la intención de abandono del profesorado

The study aimed to test mediator and moderator factors in the relationship between workplace social support (i.e., perceived support from colleagues and supervisors) and intentions to quit in a sample of teaching professionals. Specifically, utilizing job-demands-resources theory to focus on social support, we examined whether work engagement mediated the relationship between workplace social support and intentions to quit. Moreover, the potential moderator role of emotional intelligence in the proposed model was tested. The study sample comprised 1,297 teaching professionals (64.8% females) working as preschool, primary, and secondary teachers in several centers in eastern and southern Spain. The main results demonstrated that work engagement totally mediated the relationship between social support from colleagues/supervisors and intentions to quit. The findings showed that teachers’ levels of emotional intelligence significantly moderated the indirect paths between perceived support from colleagues/supervisors and intentions to quit. Teachers with the lowest levels of work engagement reported low support from colleagues or supervisors, togetherwith low emotional intelligence. Similarly, highest intentions to quit was reported by those teachers reporting low work engagement and low emotional intelligence. Finally, we discuss the relevance of these findings for basic and applied research seeking to retain a more engaged teaching force.Este estudio pretende evaluar los factores mediadores y moderadores en la relación entre el apoyo social organizacional (apoyo percibido de compañeros y supervisores) y los niveles de intención de abandono en una muestra de profesionales de la enseñanza. Específicamente, usando la teoría de demandas y recursos laborales y centrándose en el apoyo social, se examina si el engagement laboral media la relación entre apoyo social organizacional e intención de abandono. Además, se analiza el posible papel moderador de la inteligencia emocional en el modelo propuesto. La muestra del estudio esta compuesta por 1,297 profesionales de la enseñanza (64.8% mujeres) que trabajaban como docentes de Infantil, Primaria y Secundaria en varios centros del este y sur de España. Los resultados principales demostraron que el engagement laboral mediaba totalmente la relación entre el apoyo social de compañeros y supervisores y la intención de abandono. Los hallazgos mostraron que el nivel de inteligencia emocional de los docentes moderaba significativamente las relaciones indirectas entre el apoyo percibido de compañeros y supervisores y la intención de abandono. Los docentes con un nivel más bajo de engagement laboral informaron de bajo apoyo de compañeros y supervisores, así como de un bajo nivel de inteligencia emocional. Igualmente, aquellos docentes con bajo engagement laboral y baja inteligencia emocional informaron de mayores niveles de intención de abandono. Finalmente, se discute la importancia de estos hallazgos para la investigación básica y aplicada enfocada a la retención de un capital docente comprometido

Inteligencia emocional para frenar el rechazo en las aulas

En los últimos años, una de las líneas de investigación que más interés ha generadodentro del contexto educativo ha sido el análisis del papel que juegan las emociones enel aula y, sobre todo, su relación con la adaptación escolar y el bienestar de los estudiantes.El estudio aquí presentado continúa la línea de las investigaciones realizadaspreviamente con el propósito de analizar la relación de la inteligencia emocional (IE)con el rechazo recibido por parte del grupo de iguales. La muestra de esta investigaciónestá compuesta por 243 alumnos (120 chicos y 123 chicas) de educación primariacon edades comprendidas entre los 8 y 12 años que fueron evaluados a través de doscuestionarios: el Mobile Emotional Intelligence Test (MEIT) (Bresó, Ferrer & Giorgi,2013) y el Cuestionario sociométrico de nominaciones (García-Bacete & González,2006). Tras analizar los resultados obtenidos podemos afirmar que están en la línea delas investigaciones previas y defienden la relación de la IE con la aceptación grupal.En concreto, existe una relación significativa negativa entre la variable de IE Gestióny las nominaciones negativas recibidas En la parte final se discuten las implicacionesprácticas de los resultados obtenidos.In recent years, one of the lines of research that has generated the greatest interest inthe educational context has been the analysis of the role of emotions in the classroomand, above all, their relationship with school adaptation and student well-being. Thestudy presented here continues the line of research previously done with the purposeof analyzing the relationship between emotional intelligence (EI) and the rejection receivedby the peer groups. The sample of this research is composed of 243 students(120 and 123 girls) of primary education aged between 8 and 12 years who were evaluatedthrough two questionnaires: the Mobile Emotional Intelligence Test (MEIT) and theSociometric Questionnaire of Nominations (García-Bacete & González, 2006). Afteranalyzing the obtained results we can affirm that they are in the line of the previousinvestigations and defend the relation of the EI with the group acceptance. Specifically,there is a significant negative relationship between the variable EI Management and the negative nominations received. The final part discusses the practical implications of theresults obtained

Efecto de la inteligencia emocional y las tecnologías de la información y la comunicación en la satisfacción sentimental.

Introducción: Después de indagar en la forma en que las relaciones sentimentales han cambiado durante las últimas décadas y ver la gran cantidad de rupturas que se producen a diario, surgió en nosotros un gran interés por conocer que factores influyen para fortalecer las relaciones y mejorar la satisfacción en la pareja. Decidimos establecer como variables independientes el uso de TIC (tecnologías de la información y la comunicación) y la Inteligencia Emocional. Nuestro objetivo era conocer si estas dos variables afectaban sobre la variable dependiente (satisfacción con la pareja). Método: Se administró una serie de cuestionarios a una muestra de 191 personas, todas ellas casadas o con pareja, a fin de conocer su puntuación en las variables implicadas en la investigación. La inteligencia emocional se evaluó mediante el TMMS -24, el uso problemático de nuevas tecnologías mediante el upnt, mientras que la satisfacción con la pareja fue medida con el csI-16. Resultados: Los resultados muestran que las personas con mayor IE indicaron estar significativamente más satisfechos con su relación sentimental, mientras que aquellos con baja ie mostraban puntuaciones de menor satisfacción en la relación. En cuanto al uso de lasTIC, el uso no abusivo del teléfono móvil y el de las redes sociales correlacionó con mayor satisfacción sentimental, mientras que el uso de videojuegos y visionado de televisión, tanto en plataformas virtuales como de forma tradicional, no afectaba significativamente con la satisfacción. Conclusiones: Apoyando nuestras hipótesis, las personas con alta IE tienen consistentemente puntajes más altos en satisfacción con su pareja, al igual que aquellos que no hacen un uso abusivo de las TIC

In Pursuit of Work Performance: Testing the Contribution of Emotional Intelligence and Burnout

Previous research has highlighted the connection between emotional intelligence (EI) and work performance. However, the role of job burnout in this context remains relatively unexplored. This study aimed to examine the mediator role of burnout in the relationship between EI and work performance in a multioccupational sample of 1197 Spanish professionals (58.6% women). The participants completed the Wong and Law Emotional Intelligence Scale, the Maslach Burnout Inventory, and the Individual Work Performance Questionnaire. As expected, the results demonstrated a positive relationship between EI and performance, and a negative relationship with burnout, which has a mediator effect in the relationship between EI and work performance. Professionals with high levels of IE and low burnout reported the highest performance. Multiple mediation analyses showed that employees’ EI was indirectly connected to work performance via professional efficacy and exhaustion, even when controlling the effects of sociodemographic variables. The same pattern was found when multiple mediations were conducted for each EI dimension. These findings demonstrate the importance of burnout in understanding work performance and emphasize the role of EI as a protective variable which can prevent the development or chronic progression of workers’ burnout

Sexualidad y autoestima en personas con dolor crónico

Treball final de Grau en Psicologia. Codi: PS1048. Curs acadèmic 2014-2015El estudio de la sexualidad y la autoestima en personas que padecen dolor crónico es de vital importancia a la hora de indagar en la forma en que afrontan sus relaciones sexuales. Por ello, surgió el interés por conocer cómo es la sexualidad y la autoestima de las personas con esta dolencia. Se establecieron como variables independientes diferentes condiciones sociodemográficas y médicas. Nuestro primer objetivo fue analizar la sexualidad de mujeres con dolor crónico y concretamente con fibromialgia. El segundo fue conocer hasta qué punto consideran que su sexualidad está afectada por el dolor crónico. El tercero fue analizar su autoestima, y el último, conocer qué factores sociodemográficos y médicos guardan relación con la salud sexual y la autoestima de las mujeres con dolor crónico. Hipotetizamos que las mujeres afectadas por dolencias crónicas presentarían alteración en su sexualidad, considerarían que su sexualidad está afectada por el dolor crónico y tendrían una autoestima reducida. Se administró una serie de cuestionarios a una muestra de 130 mujeres afectadas con dolor crónico. Evaluamos los Problemas sexuales y la Afectación sexual derivada del dolor mediante el Cuestionario de sexualidad para pacientes de dolor crónico (Ballester y Ruiz, 2010), y la Autoestima mediante el Rosenberg’s Self-esteem Scale (Rosenberg, 1965). En primer lugar se extrajo la información acerca de características clínicas y médicas de las 130 participantes en el estudio. Seguidamente se observaron los resultados obtenidos de las respuestas en el cuestionario de forma más precisa, centrándonos ítem a ítem en las respuestas En tercer lugar se analizó las correlaciones obtenidas entre las variables de estudio. Más tarde son explicados los resultados obtenidos en los análisis diferenciales realizados mediante prueba t de Student y ANOVA. En último lugar se realizó un análisis de regresión para estimar la capacidad predictiva de ciertas variables sobre la autoestima y la sexualidad. Los resultados obtenidos muestran afectación en la sexualidad y la autoestima de mujeres que padecen una dolencia de tipo crónico. En cuanto a los factores sociodemográficos y médicos que guardan relación con la salud sexual y la autoestima de las mujeres con dolor crónico se encontró que variables como la edad, el tipo de tratamiento o el tipo de dolor crónico ejercen influencia en las variables dependientes. Tal y como se hipotetizó, tanto la dimensión Problemas sexuales como la dimensión Afectación sexual derivada del dolor, se muestran afectadas en personas que padecen dolor crónico. Este estudio pretende apoyar la literatura previa con el fin de continuar con la investigación de la sexualidad y la autoestima en personas afectadas por dolencias crónicas.After some research about how people with chronic pain were facing their sexual relationships, we became interested in knowing how sexuality and self-esteem of people with this chronic disease were. Different socio-demographic and medical conditions were established as independent variables. Our first goal was to analyse the sexuality of women with chronic pain and specifically fibromyalgia. The second was to analyse how far they consider that their sexuality is affected by chronic pain. The third was to analyse their self-esteem, and finally know what sociodemographic and medical factors are related to sexual health and self-esteem of women with chronic pain. We hypothesized that women affected by chronic conditions would present alteration in their sexuality, would consider that their sexuality is affected by chronic pain and would have reduced self-esteem. A set of questionnaires were administered to a sample of 130 women affected with chronic pain to know their scores in the variables involved in the research. We evaluated sexual problems and sexual affectation derived from the pain using a questionnaire about the sexuality among patients with chronic pain (Ballester and Ruiz, 2010); then, to evaluate the self-esteem, we used the Rosenberg's Self-Esteem Scale (Rosenberg, 1965). Firstly, we extracted the information related to clinical and medical characteristics of the 130 respondents. Then we observed more precisely the responses to the questionnaire. Thirdly, we analysed the connection between the study variables. After that, we explained the result of the differential analyses by Student t test and ANOVA. Finally, regression analysis to estimate the relationship between variables was performed. The results show impairment in sexuality and self-esteem of women who suffer chronic pain. As regards the sociodemographic and medical factors related to sexual health and self-esteem of women with chronic pain, we found that variables such as age, type of treatment or type of chronic pain influence in the dependent variables. As it was hypothesized, sexuality, both in sexual problems dimension and their respective subscales, and sexual affectation dimension resulting of pain, have shown affected in people with chronic pain. This study aims to support the previous literature in order to continue the investigation of sexuality and self-esteem in people affected by chronic diseases

Health-Care Professionals Amid the COVID-19 Pandemic: How Emotional Intelligence May Enhance Work Performance Traversing the Mediating Role of Work Engagement

Upon the eruption of COVID-19, frontline health-care workers confronted substantial workload and stress along with braving additional difficulties when performing at work. The main aim of this research was to assess the mediating role of work engagement in the direct impact of emotional intelligence on health-care professionals’ work performance. A cross-sectional study was conducted in several Spanish hospitals during the second half of 2020. A total of 1549 health-care workers (62.1% women; mean age 36.51 years) filled the Wong and Law Emotional Intelligence Scale, the Utrecht Work Engagement Scale and the Individual Work Performance Questionnaire. Our findings demonstrated that work engagement plays a mediating effect between emotional intelligence and work performance, even when accounting for sociodemographic variables. Indeed, among the three constructs of engagement, vigor dimension (a1b1 = 0.09; CI: 0.06; 0.12; p < 0.01) emerges over dedication (a2b2 = 0.083; CI = 0.05, 0.1; p < 0.01) and absorption (a3b3 = 0.047; CI = 0.02, 0.07; p < 0.01) as the most decisive one. Herewith, it is apparent that professionals with a higher self-perception of emotional intelligence report stronger levels of engagement, thereby leading to greater performance overall. The present work evinces the necessity for proactively developing the emotional competencies of the health-care workforce, especially in high-emotional demand contexts

COVID-19: How the stress generated by the pandemic may affect work performance through the moderating role of emotional intelligence

This study aimed to assess the moderating effect of emotional intelligence (EI) in the direct impact of the stress generated by the pandemic on work performance and counterproductive work behaviors (CWB) in a multioccupational sample of 1048 professionals (60.7% women). The participants filled the Wong and Law Emotional Intelligence Scale, the Impact of Event Scale 6 and the Individual Work Performance Questionnaire. The results proved a relationship between Covid stress, performance and EI, which has a moderating effect between the stress and both indicators of performance, even when sociodemographic variables were controlled. In essence, professionals with high levels of EI and low Covid stress showed the highest performance and the lowest CWB when compared to those who presented less emotional capabilities and higher stress. These results confirm the importance of EI in improving the effectiveness of work performance and reinforce the role of EI as a protective variable that can safeguard occupational health.Funding for open access charge: CRUE-Universitat Jaume

Could emotional intelligence ability predict salary? A cross-sectional study in a multioccupational sample

The study of emotional intelligence (EI) in work environments is a trending topic. However, few studies have examined the relationship between EI and salary. Therefore, the presented research aims to analyze the influence of EI on salary using a multioccupational sample. The participants were 785 subjects aged between 18 and 58 years (M = 39.41; SD = 10.95). EI ability was measured using the Mobile Emotional Intelligence Test (MEIT), while the salary was collected together with other sociodemographic variables in a questionnaire created ad hoc. After controlling for the age, gender, social class, educational level, and work experience variables, the results of correlation and regression analysis showed that participants with higher EI and emotional-repair capacity generally have higher salary. These findings provide preliminary evidence that EI is a relevant variable in achieving career success. The ability to channel and manage emotions could help employees develop stronger interpersonal relationships, leading to higher positions and greater financial compensation

Inteligencia emocional en entornos educativos: evidencias científicas

Les emocions marquen el nostre dia a dia en qualsevol àmbit de la vida, i són especialment importants en l'entorn educatiu, ja que influeixen en les relacions que mantenim, en les decisions que prenem i en els resultats que obtenim. A més, la societat s'enfronta a un període emocionalment exigent, marcat per la incertesa, la desconfiança i també per l'esperança que tot torne a ser com abans. La pandèmia ha despertat el nostre vessant més emocional i ens ha recordat la necessitat del contacte humà, la importància de cuidar els vincles socials i com és d'important percebre expressions facials al complet, sense barreres. No obstant açò, com en altres moments de crisi, la covid-19 també obri la porta a noves formes d'educar i aprendre, una porta que comunica amb un nou context en el qual la intel·ligència emocional forma part de l'educació i ens permet comprendre els nostres sentiments i els de les persones que ens envolten, un context en el qual les emocions han de jugar al nostre favor, no en contra nostra
