Estudio de Mobbing en una institución de educación superior en Hidalgo

The objective of this research is to conduct a study to determine the degree of bullying perceived or perceived in the teaching staff of a public institution of higher education (IES), located in the central part of the state of Hidalgo, based on the theoretical position and conceptual of Leymann. This research considers the conceptualization of the mobbing phenomenon, from its antecedents, concepts and studies in the organizational context. The instrument that allows the measurement of mobbing, supported with validity and reliability, is the questionnaire called LIPT-60 ("Leymann Inventory of Psychological Terrorization"). The results obtained describe the existence of mobbing in the institution of higher education, with values observed below level 1, specifically in the subscales of job loss, incommunication, and overt intimidation. That is why in higher education institutions is essential to perform this type of work in order to identify, assess and know if there are risks of workplace harassment, to be in possibility if this were the case to have timely preventive measures. In this context, analyzing the results will establish prevention strategies to reduce or eradicate workplace harassment in this organization.El objetivo de a presente investigación es realizar un estudio para determinar el grado de acoso laboral o mobbing percibido en el personal docente de una Institución de educación superior (IES) pública, ubicada en la parte central del estado de Hidalgo, basada en la postura teórica y conceptual de Leymann. Esta investigación considera la conceptualización del fenómeno del mobbing, desde sus antecedentes, conceptos y estudios en el contexto organizacional. El instrumento que permite la medición del mobbing, sustentado con validez y confiabilidad es el cuestionario denominado LIPT-60 («Leymann Inventory of Psychological Terrorization»). Los resultados obtenidos describen la existencia del mobbing en la institución de educación superior, con valores observados por debajo del nivel 1, específicamente en las subescalas de Desprestigio laboral, Incomunicación, e Intimidación manifiesta. Es por ello que en las instituciones de educación superior es fundamental realizar este tipo de trabajos con la finalidad de identificar, evaluar y conocer si existen riesgos de acoso laboral, para estar en posibilidad si así fuera el caso de disponer de medidas preventivas oportunas.

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Importancia para el mantenimiento de elementos mecánicos y fallos en turbinas de vapor: Análisis de históricos

Fault diagnosis in steam turbines is a very important task in power industry maintenance due to its influence on the reliability of power stations. However, research papers that specifically are referred to the determination of the most critical mechanical components and faults in steam turbines cannot be found. This work is focused to determine the most important components and faults in steam turbines in a Cuban power plant. For this purpose, the analysis of history data, since 1999 to 2014, of three 100 MW steam turbines was accomplished. The main achievement of this work was the definition of the most important components and faults, and that was attained by defining a new index (called as "importance" index), which intends to overcome limitations imposed by the specific characteristics of available dataEl diagnóstico de fallos en las turbinas de vapor tiene una gran importancia por su incidencia en la maniobrabilidad y confiabilidad de las Centrales Termoeléctricas (CTE), sin embargo, no es posible encontrar trabajos publicados específicamente orientados a la determinación de sus elementos mecánicos y fallos más críticos. Este trabajo se propone como objetivo determinar cuáles son los elementos mecánicos y los fallos más importantes para las tareas de mantenimiento en las turbinas de vapor de una CTE cubana durante un largo período de su tiempo de explotación. Para esto se realizó el estudio de los datos históricos de tres turbinas de vapor de 100 MW en el período comprendido entre los años 1999 y 2014. La relevancia del trabajo radicó en la obtención de los elementos mecánicos más importantes, atendiendo a su tasa de fallos y costos de mantenimientos, y de los fallos más significativos del elemento mecánico más importante durante el período estudiado, para lo cual se introdujo el cálculo de un nuevo índice dadas las limitaciones impuestas por las condiciones de organización específicas de la plant

RecruitNet: A global database of plant recruitment networks

Plant recruitment interactions (i.e., what recruits under what) shape the composition, diversity, and structure of plant communities. Despite the huge body of knowledge on the mechanisms underlying recruitment interactions among species, we still know little about the structure of the recruitment networks emerging in ecological communities. Modeling and analyzing the community-level structure of plant recruitment interactions as a complex network can provide relevant information on ecological and evolutionary processes acting both at the species and ecosystem levels. We report a data set containing 143 plant recruitment networks in 23 countries across five continents, including temperate and tropical ecosystems. Each network identifies the species under which another species recruits. All networks report the number of recruits (i.e., individuals) per species. The data set includes >850,000 recruiting individuals involved in 118,411 paired interactions among 3318 vascular plant species across the globe. The cover of canopy species and open ground is also provided. Three sampling protocols were used: (1) The Recruitment Network (RN) protocol (106 networks) focuses on interactions among established plants ("canopy species") and plants in their early stages of recruitment ("recruit species"). A series of plots was delimited within a locality, and all the individuals recruiting and their canopy species were identified; (2) The paired Canopy-Open (pCO) protocol (26 networks) consists in locating a potential canopy plant and identifying recruiting individuals under the canopy and in a nearby open space of the same area; (3) The Georeferenced plot (GP) protocol (11 networks) consists in using information from georeferenced individual plants in large plots to infer canopy-recruit interactions. Some networks incorporate data for both herbs and woody species, whereas others focus exclusively on woody species. The location of each study site, geographical coordinates, country, locality, responsible author, sampling dates, sampling method, and life habits of both canopy and recruit species are provided. This database will allow researchers to test ecological, biogeographical, and evolutionary hypotheses related to plant recruitment interactions.
