Propiedades psicométricas del inventario de estilos de manejo de conflicto organizacional ROCI - II en docentes de la ciudad de Chimbote 2021
El presente estudio tuvo como objetivo determinar las propiedades psicométricas
del inventario de estilos de manejo de conflicto organizacional ROCI II, en una
muestra compuesta por 320 trabajadores docentes de instituciones educativas
públicas y privadas de la ciudad de Chimbote, con un muestreo no probabilístico
por conveniencia, se aplicó el inventario mediante un formato Google forms, la
investigación de tipo instrumental. Se precisó la validez de constructo por medio
del análisis factorial confirmatorio donde se evidencio que los ítems aportan de
manera significativa a cada factor cuyo valor chi cuadrado relativo (χ2/gl) es de
2,09 es un índice aceptable, siendo GFI=,834, RMSEA=,058, SRMR= ,061, CFI=
,917, TLI=, 908, AIC de ajuste parsimonioso de 21471,978; en general el modelo
presenta índices de ajuste absoluto y comparativo aceptables. Se obtuvo la
confiabilidad por medio del coeficiente de Omega obteniendo valores mayores a
.70, en la dimensión de integración se obtuvo un valor de .93, en la de evitación
un .82, en dominación un .77, en servilismo un .82 y en compromiso un .77, lo
que indican un coeficiente de fiabilidad aceptable. En conclusión, el inventario
presenta una validez y confiabilidad aceptables
Does a short pollard walk transect capture butterfly and bee diversity? A test to inform pollinator monitoring and community science initiatives
1. Widespread declines in insects will threaten ecosystem functioning and services. Nevertheless, a lack of data hinders assessments of population and biodiversity trends for many insect groups and thus effective conservation actions. Implementing cost-effective, unbiased, and accurate monitoring programmes targeting different groups across a larger geographical range has therefore become a key conservation priority.
2. We evaluated a sampling protocol designed for community science initiatives targeting butterflies and bees. Specifically, we tested how well a short (200-m long) version of traditional Pollard walk transects, designed to be accessible for large numbers of community scientists, captures changes in alpha and beta diversity of these two pollinator groups.
3. We used resampling methods to simulate and assess scenarios varying in sampling intensity and frequency. We found that alpha and beta diversity of butterflies and bees were estimated at similar accuracies across different scenarios, which suggests that even short transects can provide useful information on diversity patterns for both taxa. However, common sampling frequencies resulted in low accuracies (e.g. one sample every 10 days finds on average ~50% of the species present at a site).
4. We discuss our results in the context of developing large scale, structured monitoring systems for multiple insect taxa, and how information on biodiversity patterns can inform the expansion of monitoring schemes. We explain why, moving forward, even rapid sampling designs similar to the approach tested here will be useful given a higher potential to involve community scientists, data integration techniques, and the opportunities to sample under-represented habitat type
Four good reasons to choose ketamine in the emergency department. A case series and literature review
Ketamine is a fast-acting N-methyl-D-aspartate (NMDA) receptor antagonist that can be used in a range of clinical scenarios in the pre-hospital setting and emergency department (ED). When compared with other anesthetic agents, ketamine has many unique properties, such as the ability to produce dose-dependent analgesic and anesthetic effects with a wide margin of safety. Ketamine may be used in the ED for sedation, pain management, and acute agitation treatment in the cases of benzodiazepine (BDZ)-resistant alcohol withdrawal syndrome (AWS) and substance use disorder. To highlight the efficacy and safety of ketamine, we reviewed the literature, starting with a description of four different cases of patients who presented to our ED and were treated with ketamine
