Análisis de los principios cooperativos en una cooperativa de producción de manzanilla y su contribución a la comunidad

capítulo de libroMéxico presenta problemas estructurales a largo plazo. Dichos problemas se han agravado con la apertura económica del país. El país presenta adversidad en aspectos socioeconómicos de la población como desigualdad social, pobreza, marginación y distribución de la pobreza. Aspectos que se encuentran presentes en los entornos rurales del país. Por lo que el gobierno y otros organismos propusieron la creación de cooperativas con el objetivo de mitigar estas problemáticas. El objetivo de este artículo es analizar los principios cooperativos en la Cooperativa de Productores de Manzanilla de Cuijingo S. P. R. de R. L. y como la práctica de estos principios permite satisfacer las necesidades económicas, sociales y culturales de la cooperativa, convirtiéndose en un agente activo en la mitigación de la pobreza y la desigualdad social en su comunidad. La metodología consiste en una revisión de literatura que permitió desarrollar la teoría del cooperativismo. Posteriormente se identificó el caso único con el fin de identificar los principios que han llevado a la cooperativa al cumplimiento de sus objetivos. Se realizaron observaciones de campo, revisión de material documental de la cooperativa y entrevistas semiestructuradas. Los resultados arrojan que apegarse a los valores que rigen el cooperativismo y llevar a la práctica los principios cooperativos son claves para que esta logre satisfacer sus objetivos económicos y sociales, generando beneficios a los socios y a la comunidad. Se concluye que efectivamente las cooperativas pueden contribuir a la mitigación de la desigualdad y la pobreza en sus comunidades

Training future generations to deliver evidence-based conservation and ecosystem management

1. To be effective, the next generation of conservation practitioners and managers need to be critical thinkers with a deep understanding of how to make evidence-based decisions and of the value of evidence synthesis. 2. If, as educators, we do not make these priorities a core part of what we teach, we are failing to prepare our students to make an effective contribution to conservation practice. 3. To help overcome this problem we have created open access online teaching materials in multiple languages that are stored in Applied Ecology Resources. So far, 117 educators from 23 countries have acknowledged the importance of this and are already teaching or about to teach skills in appraising or using evidence in conservation decision-making. This includes 145 undergraduate, postgraduate or professional development courses. 4. We call for wider teaching of the tools and skills that facilitate evidence-based conservation and also suggest that providing online teaching materials in multiple languages could be beneficial for improving global understanding of other subject areas.Peer reviewe

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

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity &gt; 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

First Sagittarius A* Event Horizon Telescope results. II. EHT and multiwavelength observations, data processing, and calibration

We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during the 2017 April 5–11 campaign. The observations were carried out with eight facilities at six locations across the globe. Novel calibration methods are employed to account for Sgr A*'s flux variability. The majority of the 1.3 mm emission arises from horizon scales, where intrinsic structural source variability is detected on timescales of minutes to hours. The effects of interstellar scattering on the image and its variability are found to be subdominant to intrinsic source structure. The calibrated visibility amplitudes, particularly the locations of the visibility minima, are broadly consistent with a blurred ring with a diameter of ∼50 μas, as determined in later works in this series. Contemporaneous multiwavelength monitoring of Sgr A* was performed at 22, 43, and 86 GHz and at near-infrared and X-ray wavelengths. Several X-ray flares from Sgr A* are detected by Chandra, one at low significance jointly with Swift on 2017 April 7 and the other at higher significance jointly with NuSTAR on 2017 April 11. The brighter April 11 flare is not observed simultaneously by the EHT but is followed by a significant increase in millimeter flux variability immediately after the X-ray outburst, indicating a likely connection in the emission physics near the event horizon. We compare Sgr A*'s broadband flux during the EHT campaign to its historical spectral energy distribution and find that both the quiescent emission and flare emission are consistent with its long-term behavior.http://iopscience.iop.org/2041-8205Physic

Computer application for the calculation of returns and quantities of heavy machinery for civil works projects with emphasis on earth movements in Colombia.

Por medio de una investigación realizada de acuerdo a consultas por internet, visitas a las casas comercializadoras de maquinaria pesada en Colombia y consultas realizadas en obras, se pudo determinar que no hay ningún tipo de aplicativo especializado en el cálculo de rendimientos de maquinaria para proyectos civiles, que abarque las actividades requeridas en una obra correspondientes al movimiento de tierras. Con este proyecto se estandarizaron los cálculos aritméticos correspondientes a los rendimientos de maquinarias, teniendo en cuenta la teoría de la bibliografía que se citará a lo largo del trabajo y por medio de las fichas técnicas suministradas por las casas proveedoras de maquinaria en el país, tomando como apoyo un software existente en este caso Microsoft Excel y Visual Basic generando unas bases de datos y una interfaz gráfica para proporcionar un entorno visual sencillo y permitir la comunicación con el usuario y sistema operativo. Se recurrió a procesos estadísticos que nos permitieron arrojar valores más óptimos obtenidos de las tablas de comparación de maquinaria de las diferentes marcas para generar valores de datos unificados y así poder realizar los cálculos aritméticos para los rendimientos. El aplicativo proyecta una programación de obra de acuerdo a los rendimientos calculados a partir de los procesos anteriormente nombrados, los tiempos generados dependerán de factores tales como el estado de la maquinaria, las condiciones de obra y algunos factores externos que puedan afectar este tiempo. Como producto final se obtendrán los rendimientos de las maquinarias consignadas en la investigación previa de dichos equipos existentes en Colombia y una cantidad de maquinaria necesaria para cada uno de los requerimientos del usuario, teniendo en cuenta la duración de obra proporcionada y los costos que generará la adquisición y mantenimiento de cada máquina. Los costos de mantenimiento provienen de una serie de encuestas realizadas a operarios de diferentes zonas del país y tipo de obra, las cuales nos proporcionaron la información necesaria para dicho presupuesto.Through an investigation carried out according to Internet consultations, visits to the trading houses of heavy machinery in Colombia and consultations carried out in works, it was possible to determine that there is no specialized application in the calculation of yields of machinery for civil projects, which covers the activities required in a work corresponding to the earthmoving. With this project the arithmetic calculations corresponding to the yields of machines were standardized, taking into account the theory of the bibliography that will be cited throughout the work and through the technical files supplied by the houses supplying machinery in the country, taking Such as supporting existing software in this case Microsoft Excel and Visual Basic generating databases and a graphical interface to provide a simple visual environment and allow communication with the user and operating system. We used statistical processes that allowed us to produce more optimal values obtained from the machine comparison tables of the different brands to generate unified data values and thus to be able to perform the arithmetic calculations for the yields. The application projects a schedule of works according to the yields calculated from the processes previously named, the times generated will depend on factors such as the state of the machinery, the conditions of work and some external factors that can affect this time. As final product will be obtained the yields of the machinery consigned in the previous investigation of the existing equipment in Colombia and a quantity of machinery necessary for each one of the requirements of the user, taking into account the duration of work provided and the costs that will generate the Acquisition and maintenance of each machine. The costs of maintenance come from a series of surveys carried out to operators from different areas of the country and type of work, which provided us with the necessary information
