Item type:Publication, Succumbing to the COVID-19 pandemic—healthcare workers not satisfied and intend to leave their jobs(Springer Science+Business Media, 2021-01-07)Healthcare workers are under such a tremendous amount of pressure during the COVID-19 pandemic that many have become concerned about their jobs and even intend to leave them. It is paramount for healthcare workers to feel satisfied with their jobs and lives during a pandemic. This study aims to examine the predictors of job satisfaction, life satisfaction, and turnover intention of healthcare workers during the COVID-19 pandemic. Between 10 and 30 April 2020, 240 healthcare workers in Bolivia completed a cross-sectional online survey, which assessed their job satisfaction, life satisfaction, and turnover intention in the ongoing COVID-19 pandemic. The results revealed that their number of office days predicted job satisfaction, life satisfaction, and turnover intention, but the relationships varied by their age. For example, healthcare workers’ office days negatively predicted job satisfaction for the young (e.g., at 25 years old: b = − 0.21; 95% CI: − 0.36 to − 0.60) but positively predicted job satisfaction for the old (e.g., at 65 years old: b = 0.25; 95% CI: 0.06 to 0.44). These findings provide evidence to enable healthcare organizations to identify staff concerned about job satisfaction, life satisfaction, and turnover intention to enable early actions so that these staffs can remain motivated to fight the prolonged COVID-19 pandemic. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evaluación de la contaminación acústica producida por la perforación de la piedra caliza en la cantera La Encantadora S.A.(2026-02-04)The investigation into noise pollution at the La Encantadora S.A. quarry aimed to evaluate the noise levels generated by limestone drilling and its impact on occupational and environmental health. A descriptive-correlational design was used, with on-site measurements at 29 points and surveys of 462 workers, complemented by statistical analyses (Student's t-test, Spearman's rank correlation coefficient, and Cronbach's alpha reliability coefficient).The results showed noise levels between 50.9 and 74.3 dB, exceeding the WHO's recommended limit (70 dB), although within national legal parameters (80–85 dB). The average was 60.22 dB, reflecting moderate exposure, but with critical areas along roads and in extraction zones. 85.1% of the workers perceived high levels of noise pollution, which correlated significantly with the intensity of the drilling, confirming risks of auditory fatigue, stress, and hearing loss.These findings highlight the urgent need to implement hearing conservation programs, acoustic barriers, continuous environmental monitoring, and preventative training. In short, noise management in non-metallic mining is not only a regulatory obligation but also an ethical commitment to health, human dignity, and environmental sustainability References [1] González, A., Pérez, B., & Rodríguez, S.
