Significación pronóstica de los factores histopatológicos en la supervivencia y recidiva de los tumores carcinoides atípicos pulmonares

Los carcinoides atípicos pulmonares son una neoplasia neuroendocrina de grado intermedio y escasa frecuencia que se encuadran en un espectro que abarca desde el tumor carcinoide típico hasta el carcinoma neuroendocrino de célula pequeña. Durante tiempo, su comportamiento ha sido infravalorado. El objetivo de esta tesis doctoral es el análisis de las características clínicas del tumor carcinoide atípico pulmonar, así como la importancia de los diferentes factores histopatológicos en el pronóstico de estos pacientes

Teachers' ICT-related self-efficacy, job resources, and positive emotions: Their structural relations with autonomous motivation and work engagement

Different variables related to information and communication technologies (ICT), such as digital self-efficacy for teaching, perceived institutional support for innovation, ICT positive emotions, and satisfaction with institutional support, are key factors in the teaching-learning process. The main purpose of this study is to analyze the structural relationships of these constructs with teachers' autonomous motivation and work engagement. Data were collected from 350 in-service secondary education teachers through a self-report questionnaire and were analyzed using a two-step Structural Equation Model (SEM) approach. After testing the adequacy of the measurement model, the structural model showed that all ICT-related variables significantly predicted autonomous motivation, with 26% of explained variance. ICT-related variables and autonomous motivation explained 69% of the variance of work engagement. Emotional variables also were predicted by digital self-efficacy and institutional support. Autonomous motivation and emotional variables mediated the effects of digital self-efficacy and support for innovation on work engagement. These results shed light on the critical role of these ICT-related variables for teachers’ work motivation and engagement
