RESUMO

OBJECTIVES: The "decision" to go to work, or remain absent, when unwell undermines worker energy. I is therefore understandable that low work performance is one of the main consequences of the act of presenteeism. This study evaluated the association between presenteeism, and absolute and relative work performance among fruit farm workers in Northeast Brazil. METHODS: A cross-sectional study investigated 340 paid employees of both sexes, aged 18 years or over, who worked during the 2019 irrigated fruit harvest in the municipality of Petrolina, Northeast Brazil. Absolute and relative work performance were measured using the Health and Work Performance Questionnaire. Workers who answered "one or more days" to the question "How many days have you worked this season when you were injured or unwell?" were considered presenteeists. Poisson regression with robust variance models was used to estimate the prevalence ratios of the main associations, adjusted for potential confounders. RESULTS: Presenteeist workers presented lower absolute and relative work performance than non-presenteeist workers according to the strata for most of the investigated factors. The associations between presenteeism, and absolute (adjusted prevalence ratio = 1.31) and relative work performance (adjusted prevalence ratio = 1.45) remained strong, even after multiple adjustments for other relevant variables. CONCLUSION: Presenteeist fruit culture workers self-assessed their work performance as lower than non-presenteeist ones.

RESUMO

The circular economy (CE) is an alternative economic system based on closing energy and material cycles to achieve sustainable development and create value based on innovation. In this sense, business associations (BAs) can work as intermediaries to promote CE in industrial sectors. They bring together many companies, generate trust-based relationships, support companies' strategy and collaborative innovation to construct closed-loop material flows, and increase competitiveness in sectors and regions. This study aims to show the BA's role as intermediaries of CE and promoters of industrial symbiosis (IS) as a value creation strategy among its affiliated companies (AC). Thus, this work takes the form of an exploratory case study of five different companies of the Union of Agricultural Cooperatives of Navarra (UCAN) in Spain. Researchers collected this study's data through a focus group and surveys. As a result, an original serious game was developed in 2016 and a survey in 2016 and 2020, which considers the CE's six fields of action (take, make, manufacture, distribution, use, recovery, and IS). Finally, this study proposes a methodology to promote the CE through the BAs, based on the performance of the UCAN as an intermediary of the CE and IS. Likewise, BAs' potential to promote the closure of energy and materials cycles in regions and commercial sectors such as agribusiness is demonstrated. The study also demonstrated the organizations' evolution and the improved perception of economic benefits and reduced barriers to implementing CE. This long-term analysis is valuable in novel topics such as CE.

RESUMO

In this work, deleterious effects in soils due to the presence of dielectric fluids were investigated. For this purpose, vegetable (Envirotemp® FR3) and mineral (Lubrax AV 66 IN) oils were used for simulating a set of soils contaminated in different oil contents (0.5, 1.0, 2.0, 2.5, 5.0, 7.5 and 10%) in which three 120-days soybean crop periods (SCP) were carried out using the species Glycine max (L.) Merr. Both soil and soybean plant samples were analysed on following the changes on chemical attributes, content of oils and greases (COG) in soils and phytotechnical characteristics of soybean plant. No significant changes on soil chemical attributes were found. For a 0.5% vegetable oil fraction, COG removals of 35, 60 and 90% were observed after the 1st, 2nd, and 3rd SCPs, respectively, whereas removals of 25, 40 and 70% were observed for 0.5% mineral oil fraction after the 1st, 2nd, and 3rd SCPs, respectively. There was an effectively accumulated removal on all tested oil fractions as being proportional to the integrated 120-days SCPs, suggesting a lesser number of crops for a complete abatement of oil fraction in soil. A 100% recovery on the seedlings emergence fractions was also evidenced, revealing that at least a number of 7 and 9 SCPs should be applied continuously in soils contaminated by vegetable and mineral oils, respectively, in order to no longer jeopardize soybean plant growth. Finally, an empirical prediction of the number of SCPs necessary for the complete removal of oil from the soil was proposed.
