Valoración de la Cultura organizativa y gestión de la mejora de la infraestructura de riego en la Comisión de Regantes Pisccoccocha Ccarapa, Huanta
No full textLa Comisión de Regantes Pisccoccocha Ccarapa, presenta una cultura organizativa basada en creencias y costumbres tradicionales, lo cual ha limitado el aprovechamiento eficiente del recurso hídrico e influido negativamente en la gestión de la infraestructura de riego. Ante esta situación, el presente estudio tuvo como objetivo determinar la relación entre la cultura organizativa y la gestión de la mejora de la infraestructura de riego en dicha comisión. La investigación se desarrolló bajo un enfoque cuantitativo, con un diseño correlacional. Se trabajó con una muestra probabilística de 210 usuarios, extraída de una población de 460, utilizando la encuesta como técnica de recolección de datos y un cuestionario estructurado de 40 preguntas como instrumento. El análisis se realizó mediante el software estadístico SPSS. Los resultados mostraron una relación significativa entre las variables, confirmada por la prueba de chi cuadrado (?² calculado= 58,987 > ?² crítico = 9,488) con un nivel de confianza del 95%, lo que permitió rechazar la hipótesis nula y aceptar la hipótesis alternativa. Se concluye que existe una correlación positiva entre la cultura organizativa (valores, normas, creencias y comunicación interna) y la gestión de la mejora de la infraestructura de riego, evidenciando que el fortalecimiento de la cultura organizativa puede contribuir significativamente al desarrollo y eficiencia de la gestión hídrica en contextos rurales.Tesi
Early versus Delayed Switching from Controlled to Assisted Ventilation: A Target Trial Emulation
No full textRationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone toward ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied. Objectives: Our objective was to determine whether a strategy of early compared with delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality. Methods: We conducted a target trial emulation using the prospective, global WEAN SAFE (the WorldwidE AssessmeNt of Separation of pAtients From ventilatory assistancE) dataset. Patients were eligible for switching if they were still on controlled mechanical ventilation, were not receiving neuromuscular blockers, and had PaO2:FIO2 ratios .150 mm Hg. We compared an “early switching” strategy (switch within 1 day after reaching switching eligibility criteria) with a “delayed switching” strategy (switch 1 or more days after reaching the switching eligibility criteria). The primary outcome was the 28-day cumulative incidence of successful extubation. Secondary outcomes included 28-day and 90-day ICU discharge and ICU mortality. Measurements and Main Results: A total of 1,489 patients met the switching eligibility criteria. The early-switch group had, on average, 4 additional days of being successfully extubated over the 28-day period (95% confidence interval [CI], 3–6 days; P, 0.001) compared with the delayed group, with a higher difference in cumulative incidence of successful extubation at Day 28 (7% [95% CI, 0–13%]; P = 0.04). Early switching was associated with an 11% higher cumulative incidence of ICU discharge at Day 28 (95% CI, 7–18%; P, 0.001) and an average of 7 additional days discharged from the ICU over the 90-day period (95% CI, 4–12 days; P, 0.001) compared with delayed switching. ICU mortality rates did not differ between the strategies. Conclusions: Early switching from controlled to assisted ventilation is associated with shorter duration of invasive mechanical ventilation and ICU stay compared with delayed switching
Global tracking of marine megafauna space use reveals how to achieve conservation targets
No full textThe recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-taxa tracking dataset (11 million geopositions from 15,845 tracked individuals across 121 species) to provide a global assessment of space use of highly mobile marine megafauna, showing that 63% of the area that they cover is used 80% of the time as important migratory corridors or residence areas. The GBF 30% threshold (Target 3) will be insufficient for marine megafauna’s effective conservation, leaving important areas exposed to major anthropogenic threats. Coupling area protection with mitigation strategies (e.g., fishing regulation, wildlife-traffic separation) will be essential to reach international goals and conserve biodiversity

Many large marine animals are threatened with extinction. To address this problem, the Kunming-Montreal Global Biodiversity Framework has set a goal of protecting, conserving, and managing at least 30s oceans. However, the effectiveness of area-based conservation may be limited for highly mobile marine species, especially when there is limited understanding of the spatial and temporal dynamics of animal movement in the oceans.

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project [Elektronisk resurs]
No full textThe PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.AuthorOverflow(515
