El burn-out y su impacto en los docentes de la Facultad de Contaduría Pública y Administración, Universidad Autónoma de Nuevo León = (The burn-out and its impact on teachers of the school of accounting and business administration, University of Nuevo León)

Resumen: Existen estudios que muestran que las personas en contacto permanente con otras personas llegan a mostrar alto cansancio emocional, despersonalización y baja realización personal conocidas como Burn-out (Síndrome de Quemado por el Trabajo SQT). Este síndrome puede presentarse entre individuos que trabajan con personas al exigir de ellos un desempeño laboral. Este esfuerzo genera en el recurso humano diferentes alteraciones y desgastes físicos y psicológicos que disminuyen el rendimiento laboral, repercutiendo no solo a nivel operativo y administrativo, también se refleja en la conducta del individuo así como en su estado anímico, reflejo que denota estrés laboral el cual es considerado clínicamente como Síndrome del Burn-out. Si analizamos el SQT de los docentes desde un enfoque de administración del capital humano, podemos medir el impacto en la calidad y eficiencia de las universidades. Razón por la cual, en ésta investigación se explorará básicamente: ¿En qué grado los docentes activos de la Facultad de Contaduría Pública y Administración (FACPyA) de la Universidad Autónoma de Nuevo León (UANL) padecen el síndrome de SQT?, conocer si la edad, el género y tener pareja son factores que se relacionan en sujetos que padecen el síndrome de SQT, así como saber si la antigüedad laboral, la satisfacción laboral y las relaciones laborales entre los sujetos de la investigación tienen algún grado significativo de relación con los niveles de SQT. Por lo tanto, esta investigación, tiene como objetivo conocer y describir mediante un estudio de análisis descriptivo, el impacto que tiene la sobrecarga de estrés en los docentes de la FACPyA de la UANL. Abstract: The teachers in permanent contact with persons manage to show high emotional weariness, despersonalization and low personal accomplishment known as Burn-out (Syndrome of Burned by the Work SQT) that can appear between individuals who work with persons on having demanded of them a labor performance. This syndrome from an approach of administration of the human capital, affects the quality and efficiency of the organizations. In this one investigation will be explored basically: in what degree do the active teachers of the Faculty of Public Accountancy and Administration (FACPyA) of the Autonomous University again León (UANL) suffer SQT's syndrome? Are the age, the kind and to have pair factors that relate in subjects that suffer SQT's syndrome? ¿Have the labor antiquity, the labor satisfaction and the labor relations between the subjects of the investigation some significant degree of relation with SQT's levels? This effort generates in the human resource different alterations and physical and psychological wears that diminish the labor performance, reverberating not only to operative and administrative level, also is reflected in the conduct of the individual as well as in his mental condition, reflection that denotes job stress which is considered to be clinical A Syndrome of the Burn-out (Syndrome of Burned by the Work SQT). This investigation, it has as aim know and describe by means of a study of descriptive analysis, the impact that has the overload of stress in the teachers of the FACPyA of the UANL. Key words: Syndrome Burned by the Work (SQT), stress, teachers

End of life in patients with advanced non-curable cancer : patient considerations around the moment of death

Existe conocimiento limitado sobre pacientes colombianos con cáncer avanzado preferencias con respecto a sus momentos finales, lugar de muerte y deseos posteriores a la muerte. A Para comprender mejor estas preferencias, realizamos 23 entrevistas en profundidad con pacientes entre 28 y 78 años que reciben tratamiento en dos hospitales académicos y el Instituto Nacional del Cáncer. Si bien muchos participantes deseaban una muerte pacífica, pocos se sentían cómodos discutiendo directamente el tema de la muerte. Algunos participantes más jóvenes expresó interés en la eutanasia pero no había recibido ninguna orientación o apoyo. Si bien varios participantes prefirieron morir en el hogar, algunos expresaron el deseo de morir en un hospital debido a un mejor control de los síntomas. Además, cuando se habla de post-muerte deseos, algunos participantes expresaron frustración por no poder tener estos conversaciones con sus seres queridos y sus preferencias para los arreglos funerarios.Q3Q2There is limited knowledge regarding Colombian patients with advanced cancer preferences regarding their final moments, place of death, and post-death wishes. To better understand these preferences, we conducted 23 in-depth interviews with patients between the ages of 28 and 78 receiving treatment at two academic hospitals and the National Cancer Institute. While many participants desired a peaceful death, few were comfortable discussing the topic of death directly. Some younger participants expressed an interest in euthanasia but had not received any guidance or support. While several participants preferred a home death, some expressed a desire to die in a hospital due to better symptom control. Additionally, when discussing post-death wishes, some participants expressed frustration about being unable to have these conversations with their loved ones and their preferences for funeral arrangements.Revista Internacional - IndexadaS

Small farmers' perception of factors influencing regional chemical control of Diaphorina citri

Regional Control Areas (RCAs) have been implemented in Mexico as a strategy to delay the spread of Candidatus Liberibacter asiaticus, the causal bacterium of the disease known as Huanglongbing (HLB). The implementation of an effective management of the vector insect, Diaphorina citri in the RCAs requires the knowledge, acceptance and coordinated engagement of small agricultural producers. This research assessed the perception and knowledge of 62 citrus growers regarding the operational, sociocultural and environmental factors influencing chemical control of D. citri in four RCAs within Veracruz State. According to their responses, the following factors have been identified as the operational factors with the highest influence on the effectiveness of insecticides against D. citri within RCAs: the lack of knowledge about the use of surfactants, application speed, poor calibration of sprayers and incorrect water quality. The most significant sociocultural factors are the general unawareness of the pest and the safe and proper application of pesticides. The most relevant environmental factors during application: temperature, relative humidity, and wind speed. Sociocultural index correlated with the perception of effectiveness. Therefore, it becomes necessary to consider differences among citrus growers in each region and setting out the most appropriatestrategies for vector and disease management. Highlights Some operational practices that citrus growers are not aware of may influence their perception of chemical control. The sociocultural context of growers determines their decision-taking on insecticide applications. During the application of insecticides in regional control areas (RCAs), growers do not take into account weather conditions. The effective management of D. citri requires a coordinated engagement of small growers' in RCAs.Regional Control Areas (RCAs) have been implemented in Mexico as a strategy to delay the spread of Candidatus Liberibacter asiaticus, the causal bacterium of the disease known as Huanglongbing (HLB).

CCD-based observations of PG 0856+121 and a theoretical analysis of its oscillation modes

BVRI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121 are reported. Two close, faint, red, point-like sources are resolved. They account for the previously reported IR excess observed in this hot subdwarf. In addition, the new unfiltered differential photometry of PG 0856+121 confirms its previously reported pulsational nature. A comparison with the oscillation modes of stellar models suggests the possible presence of g modes.Comment: Accepted for publication in A&A. Seven pages, four figures include

Cardiac electrical defects in progeroid mice and Hutchinson-Gilford progeria syndrome patients with nuclear lamina alterations

Hutchinson–Gilford progeria syndrome (HGPS) is a rare genetic disease caused by defective prelamin A processing, leading to nuclear lamina alterations, severe cardiovascular pathology, and premature death. Prelamin A alterations also occur in physiological aging. It remains unknown how defective prelamin A processing affects the cardiac rhythm. We show age-dependent cardiac repolarization abnormalities in HGPS patients that are also present in the Zmpste24-/- mouse model of HGPS. Challenge of Zmpste24-/- mice with the ß-adrenergic agonist isoproterenol did not trigger ventricular arrhythmia but caused bradycardia-related premature ventricular complexes and slow-rate polymorphic ventricular rhythms during recovery. Patch-clamping in Zmpste24-/- cardiomyocytes revealed prolonged calcium-transient duration and reduced sarcoplasmic reticulum calcium loading and release, consistent with the absence of isoproterenol-induced ventricular arrhythmia. Zmpste24-/- progeroid mice also developed severe fibrosis-unrelated bradycardia and PQ interval and QRS complex prolongation. These conduction defects were accompanied by overt mislocalization of the gap junction protein connexin43 (Cx43). Remarkably, Cx43 mislocalization was also evident in autopsied left ventricle tissue from HGPS patients, suggesting intercellular connectivity alterations at late stages of the disease. The similarities between HGPS patients and progeroid mice reported here strongly suggest that defective cardiac repolarization and cardiomyocyte connectivity are important abnormalities in the HGPS pathogenesis that increase the risk of arrhythmia and premature death.Peer ReviewedPostprint (published version

Efeito da terapia não cirúrgica sobre parâmetros clínicos periodontais em pacientes consumidores de cannabis

El objetivo fue analizar los efectos de la terapia periodontal no quirúrgica sobre parámetros clínicos periodontales en pacientes consumidores de cannabis. Se realizó un estudio clínico no aleatorizado con voluntarios pertenecientes a la Universidad de Antioquia. Se revisaron 40 sujetos divididos en dos grupos: consumidores de cannabis (fumadores) y no consumidores de cannabis (control). Se registraron medidas de profundidad al sondaje (PD), nivel de inserción (CAL) y sangrado al sondaje (BOP) en el periodontograma al inicio y 3 meses después de la terapia periodontal no quirúrgica. Las diferencias entre grupos fueron analizadas con la prueba Mann Whitney. Todos los datos se analizaron en SPSS y se consideraron diferencias estadísticamente significativas cuando p≤0.05. La frecuencia del consumo de cannabis diario en pacientes fumadores evidencia que el 60 % consumen 3 veces/día, el 10 % 2 veces/día y el 30 % 1 vez/día. En general, los fumadores presentaron mayor porcentaje de BOP en las dos revisiones, en comparación con el grupo de no-fumadores y esta diferencia fue estadísticamente significativa (p<0.05). En profundidad al sondaje, no se observan diferencias entre los dos grupos. Los fumadores muestran un promedio de PD al inicio de 2.09 ± 0.73 mm y 2.15 ± 0.65 mm a los 3 meses; el aumento fue leve entre estas. También, se observa que el nivel de inserción fue ligeramente mayor en pacientes fumadores que en no fumadores. En la población estudiada no se evidencian datos significativos asociados con enfermedad periodontal y el consumo del cannabis. La respuesta de los tejidos periodontales a la terapia no quirúrgica fue similar entre pacientes consumidores y no consumidores de cannabis.The objective was to analyze the effects of non-surgical periodontal therapy on clinical parameters in patients using cannabis. A non-randomized clinical study was conducted with 40 volunteers from Universidad de Antioquia divided into 2 groups: 20 participants using cannabis (smokers) and 20 non-users (control). All clinical parameters regarding probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded at baseline and 3 months after non-surgical periodontal therapy. Differences between groups were assessed with the Mann Whitney test and were considered significant when p≤0.05. Data was analyzed using the SPSS statistical software. Participants using cannabis had a frequency of use of 3 times/day (60%), 2 times/day (10%) and 1 time/day (30%). In general, smokers had higher BOP at both examinations as opposed to non-smokers, this difference being statistically significant (p<0.05). No differences were observed for PD with a mean of 2.09 ± 0.73 mm at baseline and 2.15 ± 0.65 mm at 3 months, showing a small increase between the two. CAL was also slightly higher in smokers than in non-users. There was no significant evidence in the studied population relating periodontal disease with cannabis consumption. The response of periodontal tissues to non-surgical therapy was similar between cannabis users and non-users.O objetivo foi analisar os efeitos da terapia periodontal não cirúrgica sobre parâmetros clínicos periodontais em pacientes consumidores de cannabis. Foi realizado um estudo clínico não randomizado com voluntários pertencentes à Universidade da Antioquia. Foram revisados 40 indivíduos divididos em dois grupos: consumidores de cannabis (fumantes) e não consumidores de cannabis (controle). Foram registradas medidas de profundidade à sondagem (PS), nível de inserção (NCI) e sangramento à sondagem (ISS) no periodontograma no início e 3 meses após a terapia periodontal não cirúrgica. As diferenças entre grupos foram analisadas com o teste Mann Whitney. Todos os dados foram analisados no SPSS e consideradas diferenças estatisticamente significativas quando p≤0,05. A frequência do consumo diário de cannabis em pacientes fumantes evidência que 60 % consumem 3 vezes/dia, 10 % 2 vezes/dia e 30 % 1 vez/dia. Em geral, os fumantes apresentaram maior porcentagem de ISS nas duas revisões, em comparação com o grupo de não fumantes e esta diferença foi estatisticamente significativa (p<0,05). Na profundidade à sondagem, não se observam diferenças entre os dois grupos. Os fumantes mostram uma média de PS no início de 2,09 ± 0,73 mm e 2,15 ± 0,65 mm aos 3 meses; o aumento foi leve entre estas. Observa-se, também que o nível de inserção foi ligeiramente maior em pacientes fumantes que em não fumantes. Na população estudada não se evidenciam dados significativos associados à doença periodontal e ao consumo do cannabis. A resposta dos tecidos periodontais à terapia não cirúrgica foi semelhante entre pacientes consumidores e não consumidores de cannabis

Detección del fenómeno de la inversión térmica por medio de la utilización de técnicas de tratamiento digital de imágenes basadas en sistemas de video.

Dentro de los estudios de las zonas costeras se han desarrollado técnicas basadas en sistemas de video, en las cuales el grupo de investigación en Oceanografía e Ingeniería Costera (OCEANICOS) de la Universidad Nacional de Colombia - Sede Medellín, ha venido trabajando durante varios años y ha construido el sistema HORUS. En conjunto con el Centro de Investigaciones del Clima de Colombia, se diseñó la estación de monitoreo Pajarito, ubicada en la ladera occidental del Valle de Aburrá, Medellín, Colombia, con el propósito de utilizar estas técnicas de video en aplicaciones para meteorología. Este trabajo muestra los resultados obtenidos al estudiar el proceso de estabilidad atmosférica en relación con la inversión térmica en el Valle de Aburrá por medio del sistema de monitoreo ambiental basado en cámaras de video. Se encontró mediante este sistema, que en horas de la mañana entre las 06:00 y las 09:30 (UTC-5) hay una transición de estabilidad atmosférica a algunos casos de inversión térmica, fenómeno visible en las imágenes capturadas

Geographic potential of the world’s largest hornet, Vespa mandarinia Smith (Hymenoptera: Vespidae), worldwide and particularly in North America

The Asian giant hornet (AGH, Vespa mandarinia) is the world’s largest hornet, occurring naturally in the Indomalayan region, where it is a voracious predator of pollinating insects including honey bees. In September 2019, a nest of Asian giant hornets was detected outside of Vancouver, British Columbia; multiple individuals were detected in British Columbia and Washington state in 2020; and another nest was found and eradicated in Washington state in November 2020, indicating that the AGH may have successfully wintered in North America. Because hornets tend to spread rapidly and become pests, reliable estimates of the potential invasive range of V. mandarinia in North America are needed to assess likely human and economic impacts, and to guide future eradication attempts. Here, we assess climatic suitability for AGH in North America, and suggest that, without control, this species could establish populations across the Pacific Northwest and much of eastern North America. Predicted suitable areas for AGH in North America overlap broadly with areas where honey production is highest, as well as with species-rich areas for native bumble bees and stingless bees of the genus Melipona in Mexico, highlighting the economic and environmental necessity of controlling this nascent invasion
