title: Precarious work and occupational accidents: risks associated with outsourcing in the electric power sector

description: Abstract Introduction: outsourced work in the electric power sector has peculiarities that demand consideration regarding worker’s safety. Objective: to analyze the outsourcing impacts on labor precariousness and workers’ safety in the electricity distribution industry. Methods: qualitative, descriptive study, carried out in three stages: documentary research, in-depth interviews and analysis of a fatal accident case. We used content analysis to explore the material collected, data treatment and interpretation. Results: we identified that long working hours, lower wages, poor working conditions, reduced teams and lack of supervision are important to characterize the precariousness that puts the physical and mental integrity of outsourced workers at risk. We also identified that, despite being a hazardous activity, the outsourced workers do not exercise the right guaranteed to all employees to refuse to do an activity that puts their life at risk. Conclusion: the results show that outsourcing in the electric power sector represents an increased risk of serious occupational accidents and deepens inequalities due to the differences between the treatment given to outsourced workers and the reserved for those directly employed by the company.

title: USE OF PUPILLOMETRY IN THE DIAGNOSIS OF STRESS IN PIGLETS TRANSPORTED IN A TROPICAL CLIMATE

description: ABSTRACT The objective of this study was to evaluate the reactivity of the pupillary area (PA) as a non-invasive method for diagnosing stress in piglets submitted to transport. A total of 10 journeys were monitored and grouped according to the transport distance (15 and 75 km). Were sampled 360 piglets (25±3.8 kg) to measure the PA, body temperature (BT), and serum concentrations of cortisol and creatine kinase (CK). The micrometeorological characterization of the load was performed using enthalpy comfort index (ECI). It was possible to identify an increase of 19.32% (+18.91 mm2; P&lt; 0.001) in PA of piglets transported in shorter journeys (15 km), as well as the highest mean values of BT (+ 1.24 °C; P&lt; 0.001), cortisol (+ 2.37 ng/mL; P&lt; 0.001) and CK (+ 379 U/L; P= 0.025). In this study, high correlations of PA were observed with r = 0.922, 0.900, 0.842 and 0.829 ( P&lt; 0.05) for cortisol and CK, BT and ECI of trailer, respectively. In conclusion, we state that PA reactivity is a physiological response for the diagnosis of stress of piglets transported. Further research will refine this technique in order to make this non-invasive acquisition method more practical and adaptable to different transport conditions.

title: Gender, Race and Diversity: Professional Trajectories of Black Businesswomen

description: Abstract Since the beginning of this century diversity management has been present as an important topic of studies in the field Administration in Brazil. However, research on this topic that focuses on the Black population is still scarce. In order to contribute to fill this gap, this article brings the results of a socio-anthropological investigation conducted through the biographical method and ethnographic fieldwork on the professional trajectories of two generations of Black businesswomen. These trajectories were analyzed from the societal contexts that framed them and considering gender, race and class in an intersectional perspective. The results reveal that the career paths of the second generation were built in a much more favorable societal context. However, they also show that we are still very far from gender and racial equality in the Brazilian corporate world.

title: Cultural Regulation, Geographical Indication and the (re) Signification of an Artisanal Cheese

description: Abstract Laws and norms can change the production processes of an organization, with repercussions for the tangible and symbolic composition of its products. Based on this assumption of Cultural Studies, we seek to understand how the practice of cultural regulation by a group of small producers is (re)signifying the rennet cheese produced artisanally in the Agreste region of the Brazilian state of Pernambuco. We use discourse analysis to analyze interviews and documents such as the decrees and regulations that deal with processing dairy products in Brazil, as well as those governing the process of Geographical Indication, and compare the cultural meanings that have emerged in two spheres of regulation: the public and the private. Findings reveal governmental characterization of artisanal rennet cheese has been justified by a discourse of “quality” at both the state and federal levels. However, the regulation put in place in the private sphere of the Producers Association makes use of different arguments to construct the discourse of quality with respect to the same food.

title: ASSESSMENT OF SOIL LOSS SUSCEPTIBILITY IN SANTA RITA WATERSHED IN SOUTHERN BRAZIL

description: ABSTRACT Estimation of soil loss susceptibility is of great importance for the management of watersheds. Thus, several models for soil loss prediction have been proposed. This study estimated the total annual soil loss for the Santa Rita watershed, located in southern Brazil, using the Revised Universal Soil Loss Equation. In addition, a classification to soil loss index (ISL) was proposed to identify regions with critical soil loss values. Altitude, slope, land use, and soil class data were applied to the model, in addition to spatial information for 78 soil samples collected within the study area. It was found that there is an average annual loss of 35.94 Mg ha-1 year-1, with the most substantial loss occurring in areas with predominantly exposed soil and annual cropping. Furthermore, the ISL values indicated that approximately 50% of the study area is experiencing erosion estimates above the tolerable limit. Results emphasize the need for changes in conservation and application practices present in the watershed, considering land use and soil bearing capacity.

title: OUTSORCING AND PRECARIOUSNESS IN BRAZIL’S ELECTRIC SECTOR

description: This study analyzes some outsourcing and job precariousness aspects in two important Brazilian state-owned electricity companies: Cemig (MG) and Copel (PR). By analyzing the quantitative and qualitative data obtained through interviews conducted with workers and union leaders, we observed an increase in indirect hiring, one of the main strategies adopted to reduce costs and increase productivity. Among the many aspects related to the precariousness of outsourced work, such as lower wages and weakening of collective bargains, we highlight the increase in the number of work accidents, revealing itself the most worrisome aspect of the outsourcing process in activities that, by their very nature, put workers at high risk, such as those carried out by companies in the electric sector.

title: PREDICTIVE MODELS OF CHLOROPHYLL CONTENT IN SUGARCANE SEEDLINGS USING SPECTRAL IMAGES

description: ABSTRACT Chlorophyll content is a widely used parameter for nutritional status diagnosis in sugarcane. This study aimed to develop a predictive model of chlorophyll content in sugarcane seedlings using spectral imagery analysis within the electromagnetic spectrum visible range. The experiment was carried out in a split-plot design, with two fertilization rates and three sugarcane cultivars. For chlorophyll analysis, 144 leaves were collected from seedlings. Chlorophyll contents were extracted and measured by SPAD-502 meter. Spectral images within the range of 480 to 710 nm were analyzed using reflectance, absorbance (white source), and fluorescence (source at 405 and 470 nm) responses. Predictive models were developed using multivariate regression methods such as Principal Component Regression and Partial Least Squares Regression. We chose the best model through absorbance response using variable selection and the PLSR method (R2P = 0.718 and RMSEP = 7.665). The wavelengths of 480, 490, 500, 600, 630, and 640 nm were identified as the best for total chlorophyll content determination. The spectral image processing-based method can provide a chlorophyll measurement equivalent to SPAD, with the advantage of having a higher spatial coverage over the entire leaf area. Besides, it can also support automation of the chlorophyll measurement in greenhouses.

title: USE OF BENCHES WITH REFLECTIVE MATERIAL TO FAVOR PRODUCTION OF RUBBER TREE ROOTSTOCK SEEDLINGS

description: ABSTRACT Success in production of any perennial tree depends on the use of high-quality seedlings. This study aimed to evaluate cultivation benches with reflective material and protected environments for production of rubber tree rootstock seedlings. The experiments were conducted in two types of protected environments: 35% shading aluminized screen and 30% shading black screen. Cultivation benches with and without reflective material were tested inside the protected environments. A completely randomized design with 7 replications and 5 seedlings per plot was adopted for each environment, and the environments were compared by joint analysis. Solar radiation (global and photosynthetically active) was the most influencing micrometeorological factor on plant environment and plant growth differentiation. Regardless of the environment, the use of reflective material in cultivation bench had a positive effect on production of rubber rootstock seedling (clone GT1), providing seedlings with a robust root system and better quality. The use of reflective material also improved rubber tree rootstock seedlings (clone GT1) grown in the black screen environment.

title: Checklist of mammals from Goiás, central Brazil

description: Abstract: The state of Goiás, in central Brazil, is covered mainly by the Cerrado domain, with the Alto Paraná Atlantic Forest occupying its central-southern portion. Goiás is one of the 20 Brazilian federative units without a mammal checklist. In this study, we provide the first checklist of mammals from Goiás state. We recorded mammal species based primarily on the analysis of specimens housed in scientific collections as well as on literature with associated voucher material. We listed 191 mammalian species belonging to 125 genera, 31 families and 10 orders, which represents 25.2% of the mammal species occurring in Brazil. The most speciose orders were Chiroptera (90 spp.), followed by Rodentia (43 spp.), Carnivora (19 spp.) and Didelphimorphia (17 spp.). The following orders accounted for a smaller portion of the state diversity: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.), and Perissodactyla (1 sp.). A total of 28 species (14.7%), mainly represented by medium and large-sized mammals, are nationally threatened while 12 (6.3%) are globally threatened. Our results indicate great portions of the state lacking a proper survey of mammals, especially the northwestern portion. We discuss species richness, distribution and conservation status of the mammals of Goiás state in national and regional scenarios. We highlight the need for mammal inventories based on complementary survey techniques with the collection of vouchers in order to provide karyologic, molecular, morphologic, parasitologic, and ecological data. These informations are the basis for integrative studies that lead to the understanding of current mammalian richness and diversity. Indeed, knowledge on species richness distribution in the state will guide conservation strategies, especially in areas undergoing habitat loss and fragmentation, such as the central-southern portion of Goiás.
