La evolución digital (ED) produce importantes cambios organizacionales en las empresas, que impactan en el trabajo y sus condiciones de ejecución. Sin embargo, los cambios observados se abordan, o bien desde un enfoque centrado en la tecnología, donde "la herramienta" aparece como la manera de resolver todos los problemas del mundo del trabajo, o bien siguiendo una orientación de paliativos que promueve la calidad de vida en el trabajo. A partir de datos de campo de intervenciones ergonómicas realizadas en dos empresas de servicios, el artículo se propone mostrar cuales son los factores determinantes del trabajo que evolucionan con el efecto de la conjunción de varios cambios relacionados con la ED. Los resultados destacan la necesidad de modificar los enfoques tradicionales de los proyectos de cambio tecnológico. El artículo luego propone respuestas sobre la conducción de estos proyectos, el diseño de los aparatos técnico-organizativos y las modalidades de acompañamiento del cambio. [ABSTRACT FROM AUTHOR]

The present article develops the story recount of a teaching experience carried out within the framework of the subject Introduction to Geography, which corresponds to the First Year of the Teaching Program and Bachelor's Degree in Geography at the Faculty of Human Sciences, National University of La Pampa. It is a collaborative exercise in the design of teaching and assessment practices shared by teachers, graduates and students, in actions that consist in defining epistemological and didactic agreements, the link between the fields of knowledge Specific Training in the discipline, and Teacher Training and Practices and the resignification of the different spaces. The purpose of this pedagogical intervention, in a context of action research, is to analyze situated and contextualized practices that favor the learning process of university entrants to these courses. Its permanent analysis favors a university curriculum that becomes provisional hypotheses that can be put into practice. [ABSTRACT FROM AUTHOR]

Background: Primary immunodeficiencies have a low prevalence, but their severity and high risk of mortality require a clinical approach based in diagnostic instruments that allow their early detection. Objective: To validate the PRIDE scale to determine a high level of suspicion for primary immunodeficiency diseases in Mexican population. Methods: Seventy five patients with suspicion of primary immunodeficiencies (13.9 ±11.8 years-old) were evaluated with the PRIDE scale by specialists in Allergy and Immunology in this cross-sectional study, and their results were compared with the confirmed diagnosis of primary immunodeficiency. Results: Kappa concordance coefficient with clinical diagnosis was 0.872, with an standard error of 0.072; CI 95% [0.73-1.013]. The scale showed sensitivity 98.3%, specificity 86.6%, positive predictive value 96.7%, negative predictive value 92.8%, positive odds ratio 7.3358 and negative odds ratio 0.0196. Conclusions: PRIDE scale was concordant with the diagnosis of primary immunodeficiency in the majority of patients with a previous confirmed diagnosis. The characteristics of diagnostic accuracy provide reliability to this instrument in the scrutiny of patients with probable immunodeficiency. [ABSTRACT FROM AUTHOR]

This paper analyzes Leibniz's criticisms of occult qualities. As Descartes and Boyle did before him, Leibniz rejects hidden qualities because they contradict the mechanist model of explanation, but also for other epistemological reasons. Leibniz's main argument aims to show that occult qualities are not simple forms, contrary to what Aquinas and Sennert maintain, but rather that they are relative elements that can be reduced to either metaphysical or physical principles.

The present article is part of the research project "Production Circuits, Sustainability and Rural Development. The case of the oleaginous crops and bovine cattle production circuits in the province of La Pampa." A preliminary analysis of the bovine cattle primary link components in La Pampa is carried out. In order to provide a state of affairs of the bovine stock and rodeo composition in La Pampa in reference to the whole country, statistic sources are analyzed. Also, some approximations with respect to the role of the different social actors of the production chain are presented. [ABSTRACT FROM AUTHOR]
