Los cambios legislativos en los perfiles de contratación del profesorado en las universidades públicas españolas han comportado un cambio significativo en los procesos de contratación, estabilización y promoción de este colectivo de trabajadores. El objetivo de la investigación es identificar los antecedentes del estrés y de la salud laboral de este nuevo colectivo que tradicionalmente se ha caracterizado por unos niveles relativamente bajos. La investigación empírica consiste en un estudio exploratorio a partir de la combinación de datos cuantitativos (encuestas) y cualitativos (entrevistas cognitivas) en 26 casos repartidos en tres colectivos diferentes (ayudantes, ayudantes doctores y colaboradores permanentes). Finalmente, la investigación propone un modelo con cinco antecedentes del estrés y la salud laboral: justicia, compromiso de continuidad, tiempo restante del contrato, demandas de la acreditación y recursos para alcanzarla. Acorde con los resultados, los dos últimos antecedentes (demandas y recursos) son mediados a través del constructo inseguridad. Este modelo permite la comparación de los modelos clásicos de estrés laboral con la nueva realidad universitaria española, y un primer paso hacia la generación de políticas de recursos humanos más eficientes en las universidades. ; The legal changes in the hiring profiles of universities in Spain implied significant changes in the processes of employment, stabilization and promotion of their academic staff. The aim of this research is to identify the antecedents of health and job stress of this staff, which traditionally experimented low levels of these indicators. The empirical research was based on an exploratory study that combined quantitative (questionnaires) and qualitative (cognitive interviews) data gathered from 26 cases representing three different academic positions: teaching assistants, post-dissertation teaching assistants and tenured PhD lecturers. This paper proposes a health and job stress model with five dynamics: justice, permanence commitment, time, and demands and resources related with the teaching and research staff assessment process. The findings indicate that the last two dynamics (demands and resources) are mediated by the insecurity construct. This model allows comparing the classical models of job stress with the new scenario of the Spanish universities and represents a first step for the development of more efficient human resource practices in universities. ; Peer Reviewed ; Postprint (published version)

Acute poisonings represent an emergency pathology that associates an increased risk of unfavorable outcomes or death. The mortality rate can be improved by the fast recognition of its severity, which in turn allows a prompt intervention of the medical team. In the practical approach of the case, a standardized measure of predicting the patient's evolution would be necessary, which could be applied quickly to the patient's bed and easy to calculate and apply irrespective of the evaluator. Currently, for acute poisoning cases, Poisoning Severity Score (PSS) is used, a complex and dependable tool that accurately stages the severity of the case but has the disadvantage of being quantified retrospectively. This study presents the development and validation of a linear regression model that can be applied right in the emergency department (ED) and predicts the severity of the case by estimating PSS with an accuracy of 75%. The proposed model uses ten objective and quantifiable variables representing anamnestic, clinical, and biological parameters evaluated in the early stages of the poisoning. The regression was developed in the study group consisted of 62 pediatric patients diagnosed with severe acute poisoning with cardiotoxic agents complicated by cardiogenic shock.
