El movimiento estudiantil en México y Uruguay: impulsos y deudas tras el 68

42 p.En el presente trabajo se analizan dos casos paradigmáticos de los movimientos estudiantiles latinoamericanos de 1968: el mexicano y el uruguayo. Partiendo de las numerosas similitudes que comparten se analizan las contrarias derivas de ambos movimientos, destacando la vertiente más aperturista en el caso de México y la deriva dictatorial en el caso de Uruguay. Se busca dar una explicación a estos procesos mediante el análisis de diversos factores entre los que destacan tres variables: la conexión con las guerrillas, la situación económica de sendos países y la relación de los movimientos estudiantiles con el activismo de la clase obrera.In this paper, two paradigmatic examples of the Latin American student movements of 1968 are analyzed: the Mexican and the Uruguayan cases. Starting from the many similarities they share, the opposite drifts of both movements are analyzed, highlighting the more progressive trend in the case of Mexico and the dictatorial drift in the case of Uruguay. The paper seeks to give an explanation of these processes through the analysis of various factors among which three variables stand out: the connection with the guerrillas, the economic situation of both countries, and the relationship of the student movements with the working classes

Los 68’s (sesenta y ochos) en América Latina

20-29 p.A finales de la década de los años sesenta el mundo se vio agitado por una serie de movimientos sociales que marcaron un cambio político y consuetudinario. Pero a pesar de reconocerse ampliamente como un fenómeno global en la mayoría de los casos se ha estudiado desde un enfoque nacional. ¿Qué ocurriría si se estudiara desde un enfoque regional más amplio? En este texto se tratará de abordar las similitudes y diferencias de los movimientos del 68 en América Latina para comprobar si existe un sesenta y ocho latinoamericano con características propias o si esto varía únicamente dependiendo del país en que se estudie.At the end of the 1960s the world was shaken by a series of social movements that became a political and customary milestone. However, despite being widely recognized as a global phenomenon, in most cases social movements have been studied from a national perspective. What would happen if it were to be studied from a broader regional approach? This paper will aim to address the similarities and differences of the 1968 movements in Latin America to see if they have their own characteristics or if they vary depending on the country in which these movements are studied

A join point regression analysis of trends in mortality due to osteoporosis in Spain

Osteoporosis is a major health problem in terms of fracture probability and disability. The aim of this ecological study is to identify the temporal trends in osteoporosis mortality in Spain from 1999 to 2015. Data on the Spanish population and number of deaths due to osteoporosis were obtained from the Spanish National Institute for Statistics. Age-adjusted mortality rates were estimated. Join point regression was used to identify the years when changes in mortality s and annual percentage change in mortality rates took place. Women presented a greater mortality rate decrease (p < 0.001), though this mortality difference by sex was reduced by half at the end of the period. The higher the age, the faster the mortality rate declined in women, while no clear pattern could be identified in men. In women, significant changes in trends were identified in three age groups (50-54, 60-64 and 80-84 years old). A sustained decrease in osteoporosis-associated mortality was found in women aged 75-79 and ?85 years and men aged 60-64. In conclusion, mortality caused by osteoporosis in Spain is decreasing faster in the older age ranges especially in women

Uncertainty assessment for on-machine tool measurement: An alternative approach to the ISO 15530-3 technical specification

Touch probes are commonly employed in new machine tools (MTs), and enable machining and measuring processes to occur on the same MT. They offer the potential to measure components, either during or after the machining process, providing traceability of the quality inspection on the MT. Nevertheless, there are several factors that affect measurement accuracy on shop-floor conditions, such as MT geometric errors, temperature variation, probing system, vibrations and dirt. Thus, the traceability of a measurement process on an MT is not guaranteed and measurement results are therefore not sufficiently reliable for self-adapting manufacturing processes. The current state-of-the-art approaches employ a physically calibrated workpiece to realise traceable on-MT measurement according to the ISO 15530-3 technical specification, but it has a significant limitation in that it depends on a physical workpiece to understand the performance of the systematic error contributor (u b ). To this end, the aim of this paper is to propose an alternative methodology for on-MT uncertainty assessment without using a calibrated workpiece. The proposed approach is based on a volumetric error mapping of the MT prior to the measurement process, which provides an understanding of how the systematic error contributor(u b)performs

Investigating an outbreak of non-specific building-related symptoms in workers of a general hospital

Objective: To obtain a case definition and to describe variables associated with a cluster of unspecific symptoms in healthcare workers (HCW) in a hospital building. Materials and Methods: A cross-sectional study was performed. All people working at the Residencia Cantabria building (a 200-bed building belonging to University Hospital Marqués de Valdecilla) in June 2009 were invited to complete a self-administered questionnaire, including questions on demographic data, working place and shift, working conditions and current symptoms. A cluster analysis was developed to obtain the case definition. The strength of the association between the studied variables and accomplishing the case definition was measured using odds ratios (OR) with the 95% confidence interval (CI). Multiple logistic regression was used to obtain a predictive model; its general validity was estimated with Receiver Operating Curves (ROC) and their Area Under the Curve (AUC). Results: 357 completed questionnaires were obtained. The case was defined as having at least 5 symptoms out of the eleven included. Not being ascribed to a specific shift was the strongest protective variable related with "being a case" (OR = 0.30; 95% CI: 0.17?0.54), whereas the personal antecedent of distal pain or inflammation in arms or legs was the main risk factor (OR = 4.33, 95% CI: 2.75?6.82). A six-variable predictive model has AUC equaling to 0.7378. Conclusions: A disease associated with the indoor environment quality in a hospital was characterized. A multivariate score was drafted for identifying HCW with higher risk of developing the disease in order to apply administrative prevention measures

Aproximaciones a la edición y la literatura digital

Quienes en el futuro nos lean a los que a principios del siglo XXI escribimos sobre cuestiones como esta que nos ocupa, la edición digital, es posible que nos vean como nosotros a aquellos que difundían a finales del siglo XV o comienzos del XVI los misterios del nuevo invento para fabricar libros. Como ellos, nosotros somos conscientes de que estamos ante un cambio tecnológico que altera las cosas sin que sepamos definir o anticipar muy bien en qué sentido. A veces uno podría pensar que el ser humano es más capaz de inventar que de comprender sus inventos

Burnout syndrome in Spanish medical students

Background: Burnout syndrome is a frequent syndrome related to people that feel a deterioration in their daily activities due to highly demandant psychological requirements in their workplaces. Within last decades, this syndrome has been studied across medical professionals, concluding that stress levels that physicians suffer is high enough to make them develop burnout syndrome. In the case of medical students, there are some recent studies, although with small samples. For this reason, given that this phenomenon may produce a huge impact in medical students' development, the aim of this study is to analyze the influential factors that may contribute to its occurrence. Methods: The necessary information was gathered through a web-based questionnaire, divided in two parts. The first part of the survey included questions related to personal aspects of the students. Burnout related questions (second part) were divided in three subscales to evaluate exhaustion, cynicism, and academic efficacy levels. Results: Family support for studying medicine is associated with lower burnout levels in all three scales of the Maslach Burnout Inventory. The number of years spent in the degree show the opposite trend: the more years in the degree, the higher score in all burnout scales. Conclusions: Burnout syndrome is a problem among medical students in Spain that increases with the number of years studying medicine. It should be also noticed that family support and vocational studies are independent factors related to lower levels of burnout
