We conducted a cross-sectional survey to assess the anxiety, distress, and turnover intention (likelihood to leave their current job) of healthcare workers in Peru during the COVID-19 pandemic. Our results reported that 21.7% healthcare workers in Peru experienced severe anxiety, whereas 26.1% of them experienced severe mental distress. A higher level of education related with a lower level of anxiety. Younger workers had a higher level of turnover intention than their older colleagues did. Healthcare workers in the private sector had a higher turnover intention than those in the public sector. Most importantly, people who were geographically far from Lima, the epicenter in Peru, during the outbreak experienced less anxiety and mental distress, corroborating the ripple effect and disconfirming the typhoon eye theory. However, the direction of these relationships can change depending on t...

Sinay H, Mahulette F, YáñezJA. 2022. Determination of free radical scavenging activity, phenolicand flavonoid content of seven corn cultivars from the Southwest Maluku District, Indonesia.Biodiversitas 23:5974-5981.The variation of corn (Zea maysL.) kernel might be considered as a surrogate indicator of the phytochemical and bioactive content. This study aimed to determine the phenolics, flavonoids, and free radical scavenging activity of seven local corn cultivars from Kisar Island, Southwest Maluku District in Indonesia. Sample extraction was done by the maceration method. Flavonoid content wasdetermined using the Dowd method, and total phenolic content was performed using the Folin-Ciocalteu method. Free radical scavenging activity was determined using the DPPH radical scavenging method. One-way ANOVA was performed with Duncan multiple range tests to assess the differences between c...

“The general objective of this article was to construct and describe the psychometric properties of a scale of selfcare behaviors against COVID-19. It was a descriptive, cross-sectional, psychometric validation study of a scale created to measure self-care behaviors in relation to COVID-19 in a total sample of 333 probabilistically selected. Qualitative validity was evaluated by a review of 10 experts and quantitative validity by means of exploratory factor analysis using the principal components method. Internal consistency was measured with Cronbach’s alpha twice and the test-retest was evaluated by calculating the intraclass coefficient. The final scale consisted of 29 items. The Kaiser-Meyer-Olkin test of adequacy yielded a value of 0.926, and the Bartlett’s test of sphericity X² = 4611 with a p-value < 0.001. The variance explained by the three retained factors with a total o...

El presente estudio tiene como objetivo validar y aplicar un instrumento para evaluar la relación entre el apoyo institucional, la alfabetización tecnológica y la autoeficacia sobre la intención de participar en el metaverso de Facebook utilizando la teoría cognitiva social. Realizamos un estudio analítico transversal de 410 ciudadanos en Perú para evaluar la influencia del apoyo institucional, la alfabetización tecnológica y la autoeficacia en la intención de participar en el metaverso de Facebook durante la pandemia de COVID-19. El modelo de investigación se validó utilizando modelos de ecuaciones estructurales de mínimos cuadrados parciales (PLS-SEM) para establecer la influencia de las variables en el modelo. Se encontró que el apoyo institucional y la alfabetización tecnológica influyen positivamente en la autoeficacia de participar en el metaverso mediante correlaci...

This study was designed to determine the contents of total polyphenols, flavonoids, flavonols, flavanols, and anthocyanins of purple corn (Zea mays L.) extracts obtained with different methanol:water concentrations, acidified with 1% HCl (1 N). Another objective was to determine the antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), and deoxyribose assay, individual phenolic compounds by high-performance liquid chromatography (HPLC), and endogenous antioxidant enzyme (superoxide dismutase [SOD], catalase [CAT], and total peroxidase [TPX]) activity and lipid peroxidation activity (thiobarbituric acid-reactive substances [TBARS] assay) in isolated mouse organs. Overall, the highest total content of polyphenols, anthocyanins, flavonoids, flavonols, and flavanols was obtained wi...

“The general objective of this article is to show the relationship that exists in the COVID-19 pandemic, the mental health of people and the propensity for work-related accidents in companies. Various results are shown that detail how COVID-19 has generated and is generating mental alterations in people such as post-traumatic stress disorder, PTSD for its acronym in English. Likewise, data are presented that report the influence of mental health as a precursor to workplace accidents in different industries, with which it can be concluded that COVID-19 needs a comprehensive approach in companies to prevent it from negatively impacting workers and they end up accident during their daily work. Some concrete actions are proposed to promote and avoid in companies so that workers can be better managed in times of a COVID-19 pandemic.“

Food is usually recognized as a limited resource in sustainability, recognized by the United Nations (UN) Sustainable Development Goal (SDG) 2, which aims to achieve zero hunger. It is expected that the circular economy (CE) can improve processes related to food production. The objective of the present study was to apply a bibliometric approach using VOSviewer visualization software as a research tool to analyze the relevant literature from the Scopus database in the field of circular economy and its relation to improvements in food issues throughout 2012–2021. A total of 1316 articles were analyzed. Italy was the most productive country with 313 articles, with Wageningen University & Research the organization with the most publications with 39 articles. The top 10 institutions originated from Italy, The Netherlands, France, and Denmark. Sustainability was the most productive journal w...

“The aim of this study was to evaluate the probability of buying food away from home according to the type of household using the logit model, as well as the sociodemographic characteristics of the heads of household, and how much income expenditure represents. A cross-sectional study was carried out using the National Household Survey (ENAHO) 2019 database. After joining the database, the household type variables were created. To calculate the probability with the “logit” model of purchase, the variables—family size, income, types of household, and total expenditure— were selected as a measure of the purchasing power of the family. A statistically significant association (p < 0.05) was found between the probability of consumption and the variables: age of household members, predominance, nuclear without children–married, nuclear with children–cohabitant, nuclear with child...

“The Argentine health system has three subsectors: private, social works, and public. It is essential to consider the user’s perceptions through studies that measure the intention to revisit, through self-perceived care quality, to obtain results from the health care process and adjust the services provided accordingly. A correlational, cross-sectional, and non-experimental study has been carried out. A total of 407 people were surveyed using a self-administered questionnaire with a five-point Likert scale. The model considered four variables: quality of the use of health programs, satisfaction, confidence, and revisit intention. Second-generation statistics were adopted through multivariate evaluation using partial least squares structural equation modeling (PLS-SEM) to calculate the correlation values between the study variables. The direct route between the quality of health servi...

“: Successful project management depends on ensuring the project’s objectives. Within these objectives, technical success is associated with achieving the expectations of the project baseline. The baseline of the project is made up of the definition of the scope (WBS), time (schedule) and costs (S curve) of the project. Directly, the project is expected to be technically successful if it manages to deliver its full scope on schedule and without associated cost overruns. Baseline performance management is how project managers track and control the progress of deliverables, timelines and associated costs. In a traditional approach, for waterfall-type projects that use the critical path paradigm, the baseline performance management tool par excellence is earned value management (EVM). Earned value management, in practice, works well when project costs are monitored and controlled; howev...
