The objectives of the study were to describe the feasibility of an intervention in older women based on folk dances of the Colombian Caribbean region, and to analyze the effects of the intervention on physical fitness and health-related quality of life (HRQoL). A pilot study was conducted in a sample of 27 participants, 15 in the intervention group (IG) and 12 in the comparison group (CG). Caribbean Colombian dance rhythms were introduced as an intervention that lasted 12 weeks. Recruitment and retention was not optimal. Treatment fidelity components indicated that intervention was administered as intended. IG participants showed positive and statistically significant changes in some components of physical fitness. No significant changes were observed in HRQoL indicators for either group. In conclusion, the intervention was feasible, but recruitment and retention was challenging. Folk dances of the Colombian Caribbean region provoked significant results in physical fitness but not in HRQoL.
Complex thinking is an important tool for effective decision-making, as it helps people to better understand uncertain situations by considering the multiple variables and relationships involved in a situation, thus being able to identify patterns and connections that would not otherwise be evident. This article presents the results of a bibliometric study to identify academic publications that consider the correlation between decision-making in the business area and complex thinking competency and its sub-competencies. The intention was to have a theoretical horizon that provides a complete overview of the current academic situation regarding the correlation of both professional skills to identify areas of opportunity for new studies. Methodologically, we conducted a literature review using Scopus and Web of Science databases under the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) protocol from which a sample of 339 articles related to both topics was obtained. R, Rstudio, and Bibliometrix were used for the quantitative analysis of the data. The results showed an academic tendency to associate decision-making in business with critical thinking, paying little attention to the other sub-competencies of complex thinking. Furthermore, we found a concentration of research in specific universities and countries, repeating a tendency to study only a few sub-competencies. Overall, this work sheds light on the broad opportunity to link the complex thinking macro-competency with decision-making in business, to provide more extraordinary skills and tools to future professionals.
Abstract. The classical Economic Production Quantity (EPQ) inventory model does notconsider ordering and holding costs of raw materials. In this direction, this paper considers the ordering and holding costs for both raw materials and nished product. Basically, four EPQ inventory models are developed from an easy perspective that has not been considered before. It was found that the ordering and holding costs of raw materials must be taken into account, because they signi cantly impact on the optimal production lot size of the nished product in both EPQ without shortages and EPQ with shortages inventory models. Furthermore, an EPQ inventory model that determines the optimal lot size for a product that requires more than one raw material, and an EPQ inventory model that obtains the optimal batch size for multiple products, which are manufactured with multiple raw materials, are proposed. Numerical examples are presented in order to illustrate the use of the proposed inventory models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
