Perturbaciones tropicales en el Atlántico norte suroriental. Estado de la cuestión y perspectivas de futuro

This study analyzes tropical disturbances in a region usually not affected by these events, the southeastern North Atlantic. This is an extensive area between Macaronesia and the coasts of northwest Africa and the southwest of the Iberian Peninsula. In the context of climate change, a statistical analysis has been conducted of the main database of the National Hurricane Center for the Atlantic basin, as well as a bibliographical compilation, in order to analyze the temporal and spatial evolution of these phenomena. The starting hypothesis is to verify the existence of an increase in the risk of these situations in the region of study, through research that characterizes and charts these phenomena. The results indicate that, although with long periods of recurrence, some events with notable impacts had occurred before the first systematic records were kept. In addition, over the last fifty years, a much more reliable period from a scientific perspective, there has been an increase in their number, especially in recent decades. Furthermore, an approximate estimate is made of the population likely to be affected by tropical disturbances, which estimates that more than twenty million people are at risk.Se presenta un estudio sobre las perturbaciones tropicales en una región habitualmente no afectada por estos eventos, el Atlántico norte suroriental. Se trata de una extensa área entre la Macaronesia y las costas del noroeste de África y suroeste de la península ibérica. En el contexto del cambio climático se hace un análisis estadístico de la principal base de datos del National Hurricane Center para la cuenca atlántica, así como una recopilación bibliográfica, con el fin de analizar la evolución temporal y espacial de estos fenómenos. La hipótesis de partida es comprobar la existencia de un incremento en el riesgo de estas situaciones en la región de análisis, para lo que se elabora un estudio que las caracteriza y contabiliza. Los resultados señalan que, aunque con periodos de recurrencia largos, se han dado algunos eventos con destacados impactos antes del comienzo sistemático de su registro. Además, en los últimos 50 años, periodo mucho más fiable desde una perspectiva científica, se constata un aumento en su número, especialmente en las últimas décadas. Asimismo, se hace una aproximación a la población susceptible de ser afectada por las perturbaciones tropicales, la cual se estima en más de 20 millones de personas en riesgo.This research is part of the research project “MYRIAD-EU: Multi-hazard and sYstemic framework for enhancing Risk-Informed mAnagement and Decision-making in the EU”

Research Results Transfer towards the Productive Sector via Research Collaboration in Four Colombian Public Universities

This article shows the determining factors in the research results transfer towards the productive sector via research collaboration in four Colombian public universities. Thirty heads of units in the aforementioned universities were interviewed, which served to determine eleven cases of study and conduct interviews with thirty-five participants ranging from researchers, participant in formation and business people, in each case, it was found that especially in the last decade universities have turned to creating capacities for research collaboration as well as an openness in participants to create links that not only go in favor of enriching the productive sector but also in strengthening formation and research processes. It was concluded that there is a recent growing interest in the different actors in strengthening the bonds between the universities and the productive sector, though there may be some difficulties in the process of research collaboration due to the lack of an appropriate regulatory framework

Hipoacusia neurosensorial súbita idiopática: caracterización y resultados terapeúticos. Hospital universitario “General Calixto Garcia”. Octubre 2008- octubre 2016”

Introducción La hipoacusia neurosensorial súbita idiopática es un trastorno auditivo de causa desconocida, se debe considerar como una urgencia médica dentro de la otorrinolaringología. Se define como: hipoacusia neurosensorial, mayor a 30 dB de pérdida en al menos tres frecuencias consecutivas, que se desarrolla en un periodo de horas hasta 3 días. Objetivo: Describir las características clínicas y la evolución audiológica de los pacientes con hipoacusia súbita idiopática en el Hospital Universitario Calixto García en el período octubre de 2008- octubre de 2016. Método: Estudio descriptivo, prospectivo y longitudinal. Se designó como universo de estudio a todos los pacientes atendidos   en el Cuerpo de Guardia e ingresados en el servicio de Otorrinolaringología del Hospital con diagnóstico de hipoacusia súbita quedando constituida la muestra por 43 pacientes en los cuales no se encontró la causa de la hipoacusia. Resultados: El 47% de los pacientes presentó vértigo y acufeno relacionados con la hipoacusia. El 39% de los casos tuvo una tasa de recuperación de la audición completa. El 57,6% de los pacientes consultaron antes de los 3 dias de iniciado el cuadro y tuvieron una recuperación buena o completa de la audición. La curva audiométrica que predominó fue la tipo plana y cofosis (30,2% y 20,9%). Conclusiones: En la mayoría de los pacientes se logró alguna mejoría en su audición luego del tratamiento médico. Existen factores de mal pronóstico como la gravedad de la hipoacusia, la asociación de acufenos y vértigo y el inicio tardío del tratamiento.

Introduction:  Aging constitutes the main demographic problem in Cuba, and hearing loss is one of the most frequent chronic conditions in older adults.Objective: To describe the clinical and epidemiological characteristics of elderly patients with hearing loss, treated in Calixto Gracía University Hospital during the period from September 2015 to September 2016.Material and Method:  A descriptive cross-sectional study was conducted in “Calixto Gracía” University Hospital during the period from September 2015 to September 2016.  The population (N) was composed of 387 elderly patients, who went to the doctor´s office during the period under study.      Results: Hearing loss predominated in patients aged from 65 to 79 years (67,2%), and the male sex was the most affected by this disability (69,5%).  Hearing loss in the elderly was frequently associated with other chronic conditions such as cardiovascular diseases.  Age-related hearing loss (Presbycusis) or hearing loss associated with age was the most frequent cause of deafness.Conclusions: Hearing loss was a frequent disability in male elderly patients. It was associated with non-communicable chronic diseases.  Sensorineural and mixed hearing losses of moderate and severe intensity were the most frequent ones found in the tonal audiometry. Keywords: Hearing loss, older adult, Age-related hearing loss (Presbycusis), hearing disability, elderly, aging. </p

Cost-effectiveness of multicomponent interventions in type 2 diabetes mellitus in a cluster randomised controlled trial: the INDICA study

Objective: To analyse the cost-effectiveness of multicomponent interventions designed to improve outcomes in type 2 diabetes mellitus (T2DM) in primary care in the Canary Islands, Spain, within the INDICA randomised clinical trial, from the public health system perspective. Design: An economic evaluation was conducted for the within-trial period (2 years) comparing the four arms of the INDICA study. Setting: Primary care in the Canary Islands, Spain. Participants: 2334 patients with T2DM without complications were included. Interventions: Interventions for patients (PTI), for primary care professionals (PFI), for both (combined intervention arm for patients and professionals, CBI) and usual care (UC) as a control group. Outcomes: The main outcome was the incremental cost per quality-adjusted life-years (QALY). Only the intervention and the healthcare costs were included. Analysis: Multilevel models were used to estimate results, and to measure the size and significance of incremental changes. Missed values were treated by means of multiple imputations procedure. Results: There were no differences between arms in terms of costs (p=0.093), while some differences were observed in terms of QALYs after 2 years of follow-up (p=0.028). PFI and CBI arms were dominated by the other two arms, PTI and UC. The differences between the PTI and the UC arms were very small in terms of QALYs, but significant in terms of healthcare costs (p=0.045). The total cost of the PTI arm (€2571, 95% CI €2317 to €2826) was lower than the cost in the UC arm (€2750, 95% CI €2506 to €2995), but this difference did not reach statistical significance. Base case estimates of the incremental cost per QALY indicate that the PTI strategy was the cost-effective option. Conclusions: The INDICA intervention designed for patients with T2DM and families is likely to be cost-effective from the public healthcare perspective. A cost-effectiveness model should explore this in the long term.This study received financial support from the Spanish Ministry of Economy, Industry and Competitiveness (Instituto de Salud Carlos III), grants: ADE10/00032 and PI16/00769, jointly funded by the European Regional Development Fund (FEDER) ‘A way to make Europe’.

Cuantificación microlisimétrica del consumo de agua residual tratada en la nochebuena (Euphorbia pulcherrima Willd. ex Klotzsch)

En un cultivo de nochebuena en un invernadero instrumentado en Jiutepec, Morelos, se midió el consumo de agua residual tratada (ART) con microlisímetros de succión de macetas de polietileno de 15 cm de diámetro con sustratos de granulometría similar N, V y A, donde N = tierra de hoja/ tezontle/fibra de coco en proporción 60:20:20; V = tierra de hoja/tezontle/agrolita/fibra de coco (86:7:3.5:3.5); A = fibra de coco/tierra de hoja/agrolita (40:40:20), y el consumo de agua mediante microlisímetros de balance con sustrato N (BN); 11 de 22 variables presentaron diferencia significativa; BN tiene los valores más altos y V los menores; N es igual a A, para todas las variables analizadas. Las brácteas tienen diferencias en área, peso fresco y peso seco, sin diferencias en color L*, C* y h; las hojas no tienen diferencias en área ni en contenido de clorofila, y sí tienen en peso fresco y seco. Peso fresco y seco de raíz sin diferencias significativas. El sustrato A presentó mejores resultados agronómicos que N y V. El consumo de ART de la nochebuena puede ser afectado por tipo de planta y método de riego. En las semanas después del trasplante 2 (posterior al pinchado), 8, 9 y 10 (inicio de pigmentación), existen diferencias entre tratamiento y coincide con un periodo de disminución del consumo de ART. El microlisímetro de succión es una herramienta para cuantificar el consumo de ART en nochebuena

Diálogo entre las humanidades

Published¿Cuál es el legado de las humanidades? Es una pregunta que pareciera se debilita en los contextos universitarios pero que todavía es objeto de disputas y perspectivas teóricas, en las primeras décadas del siglo XXI. Aquí asumimos que, a pesar del avasallamiento de las ciencias aplicadas y la tecnología en los contextos de Educación Superior; cabe seguir cuestionándonos sobre las “Humanidades” y sin renunciar al pensamiento crítico, ubiquemos su capacidad dialógica y de interpelación entre conocimientos y realidad. Diálogos Entre las humanidades, reúne textos de profesores de varias universidades de Santiago de Cali, México y Cuba, con variedad de enfoques, invitando a un ejercicio plural y concreto del pensamiento. Este texto se constituye en un punto de cruce de los clásicos diálogos con la filosofía, la historia, la estética y la ética con nuevos problemas de la comunicación social, la publicidad y a la educación para la paz. Las humanidades se encuentran hoy más vigentes que nunca, aportando claves e instrumentos teóricos para el análisis de temas y problemáticas de nuestro tiempo

European Journalism Observatory- a platform for training and professional networks in the Faculty of Information Sciences

The launching of a Spanish platform within the Observatory will serve as a training laboratory for undergraduate and graduate students of the Faculty of Information Sciences at the same time as for establishing a professional media network in and outside Spain. The European Journalism Observatory (EJO) is a network of 14 non-profit media research institutes in 11 countries where Spain continue to be the missing element. All researchers in the EJO network actively strive to transfer their knowledge to the media industry as well as interested publics outside the scientific community, as a platform to enable online availability of at least a portion of many publications in several languages

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
