title: Plurality of governance on cattle ranches: case studies in Brazil

description: ABSTRACT The present article investigated the plural forms of governance that have been adopted in buying and selling transactions by cattle ranches with differentiated markets. In addition, it proposes to describe and explain which determinants influence this plurality, based on the theoretical principles of transaction cost economics. The analysis was based on the observation of both upstream transactions and commitments and agreements established downstream by two ranches, both specialized in beef cattle, but with different competitive strategies. The adoption of plural forms demonstrates diverse competitive advantages, insofar as both can meet the requirements of different distribution channels or increase production capacity. The results indicated that the governance structures adopted by the ranchers studied responded to the demands of the strategies adopted for their production units. Thus, the adopted governance structures should be aligned with their strategies for the cattle ranches to be successful.

title: Fatal work accidents in Palmas, Tocantins, Brazil: missed opportunities of information

description: Abstract Objective: to estimate the underreporting of fatal work accidents (FWA) in information systems of the Ministry of Health, State Secretariat of Public Security (SSP), Ministry of Labor and Social Security Secretariat, from 2007 to 2015, in Palmas, Tocantins. Methods: the data sources of the FWA cases were the Mortality Information System (SIM), the Hospital Information System of the Unified Health System (SIH-SUS), the Information System on Diseases of Compulsory Declaration (SINAN), the Annual Social Information Report (RAIS), the Information System of Communication of Work Accidents (SISCAT), police reports (PR), Cadaver Referrals (GEC) and Cadaveric Examination Reports (LEC). To calculate underreporting within each system, a single database was created with the records of all sources, eliminating repetitions. Results: 114 cases were identified. Under-reports identified were: SIM, 28.9%; SINAN, 44.7%; SSP, 55.3%; RAIS, 73.1%; SISCAT, 65.4%, for insured workers. Conclusion: the best performance in registry is from SIM. Extensive underreporting was observed in all other sources. Mortality records due to FWA are underestimated. Action to improve recording, especially at SIH-SUS, RAIS, SISCAT, and SSP, followed by SINAN and SIM, are required.

title: Water relations of chives in function of salinity and circulation frequency of nutrient solutions

description: ABSTRACT Hydroponic cultivation using saline waters is an alternative for agricultural production, especially in the cultivation of vegetables. Therefore, the present work was conducted with the objective of evaluating the water consumption, water use efficiency and water content, as well as dry matter partitioning of chives (Allium schoenoprasum), cv. Todo Ano Evergreen – Nebuka exposed to six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 dS m-1), applied at two circulation frequencies (twice a day at 8 and 16 h; and three times a day - at 8, 12 and 16 h). The level in the nutrient solution reservoir, which decreased according to the water consumption by plants, was replaced with the respective saline water (Experiment I) and supply water (Experiment II). Both experiments used a completely randomized design, in a 6 x 2 factorial scheme, with five replicates. It was observed that increased circulation frequency and the use of supply water in the replacement mitigated the effects of salinity on water consumption, water use efficiency and water content in the plant. However, with the increase in nutrient solution electrical conductivity, dry matter allocation in the roots increased, to the detriment of the shoots.

title: Mensuração da Pobreza Multidimensional Rural nas Mesorregiões Norte e Jequitinhonha de Minas Gerais

description: Abstract: The aim of this study is to investigate and measure the intensity of rural multidimensional poverty through the Fuzzy sets, having as geographic cut North and Jequitinhonha mesoregions of Minas Gerais state and its familiar farmers as target public. The methodology is based on the construction of the Multidimensional Rural Poverty Fuzzy Index and on the calculation of the weights of each dimension. As for the results, these are aligned with what Amartya Sen defends in the Capability Approach, because although the dimension referring to income and work have presented the greatest weight in the measurement of poverty, factors such as education and health also merit attention due to the greater intensity presented. Therefore, this segment should be assisted by structuring policies with constant improvements in education, health and infrastructure, in order to meet the particularities of each locality, according to the real deprivations suffered by family farmers.

title: Mapping and characterization of intensity in land use by pasture using remote sensing

description: ABSTRACT The current demand for food has been met through the exploitation of natural reserves. Brazil has 26% of its extension occupied by agricultural uses, 62% of which are pastures. Degraded pastures have greater land use intensity than well-managed pastures, leading to greater degradation of the environment. Land use classification systems consider that pastures are well managed, a misconception for the Brazilian reality. Based on this approach, it was aimed to develop a methodology for mapping the intensity of land use by pasture via remote sensing. The method of mapping was developed and validated in basins with different soil and climatic characteristics. Three calibrations were performed based on NDVI values to ascertain the influence on the results, being evaluated from the field campaigns and the kappa and weighted kappa indices. The kappa and weighted kappa indices presented reasonable and moderate agreement, respectively. The results were considered as satisfactory for the three calibrations, evidencing that the degree of degradation of the pastures can be estimated in a simple way by remote sensing. The Limoeiro River Basin has around 46.9% of pastures, at least, heavily degraded and 96.6% with some degree of degradation, which contributes to degradation of the natural resources and reduction of livestock farming and economic potential of the basin.

title: Psychological demands, low social support and repetitiveness: occupational factors associated with musculoskeletal pain in shoe industry workers

description: Abstract Introduction: musculoskeletal disorders (MSDs) are a major public health problem, causing great physical and psychological suffering, work disability, and imposing heavy costs on workers and society. Objective: to analyze shoe industry workers, estimating the prevalence and factors associated with MSDs of the neck region and upper limb. Method: a cross-sectional study carried out with a stratified random sample of 446 workers interviewed with use of a questionnaire. Sociodemographic, lifestyle and occupational variables (physical and psychosocial demands) were measured. Factor analysis was applied on variables related to physical demands and multiple logistic regression was used to identify the factors associated with the outcome. Results: MSD prevalence in previous 12 months was 47.3% in the neck, shoulder or upper back (proximal extremities) and 37.4% in distal extremities. MSDs in proximal extremities were associated with psychological demand, low supervisor support, working time at the company (≥ 8 years) and female sex. MSDs in distal extremities were associated with psychological demand, low supervisor support, repetitive strain injuries and female sex. Conclusion: MSDs in upper limbs were highly prevalent in the shoe industry, with psychosocial demands having a significant role on their occurrence, whose control requires intervention on working conditions.

title: Advances in vegetative propagation of Olive tree

description: Abstract In Brazil, there is a growing interest in the crop of the olive tree, especially in those regions considered suitable for cultivation, where low temperatures occur between 8ºC and 10ºC in the period before flowering. The areas with these characteristics are located mainly in the South and Southeast regions of the country, characterized by a temperate climate in function of altitude, with the occurrence of natural vernalization. The propagation is an integral part of the production chain and the first step towards the implantation of the olive tree crop or renovation of the existing orchards. Obtaining quality seedlings, besides guaranteeing uniformity and reliable varietal origin, is a factor that influences the whole life of the orchard, allowing to maximize the effects of climate and soil and mainly of crop treatments adopted for the culture. In the Laboratory of Propagation of Fruit Plants of the Department of Phytotechnology of the Eliseu Maciel School of Agronomy of the Federal University of Pelotas, we have sought to research micropropagation and minipropagation allied to the clonal gardens kept in a protected place, reducing the physical space and improving, mainly, the crop protection control. Olive tree seedlings propagated by different methods of asexual propagation, such as micropropagation, microcutting and minicutting, and they have their completion until the complete development in no-soil cultivation systems.

title: POLEMIC OF LITERACY IN BRAZIL OF PAULO FREIRE

description: ABSTRACT Debates linked to academic theories have been intensifying in the Brazilian political scene from statements shared sharply by governmental authorities. Thus, there is evidence of efforts to depreciate the legacy left by Paulo Freire and the contributions of the literacy approach to the writing acquisition process. Contrasting with the ideals shared by the authorities, I present some contributions by Paulo Freire to current demands for empowering (1) scientific education in schools and (2) critical training of female teachers. These contributions are appropriated by contemporary research in literacy studies, produced in the Brazilian and international academic context. As forwarding, I emphasize the relevance of teacher education mediated by investigative practices, as already proposed by the mentioned educator. It can guarantee to the female teachers the autonomy necessary for their own methodological constructions and professional confrontations.

title: THE IMPACT OF WELL-BEING AT WORK AND PSYCHOLOGICAL CAPITAL OVER THE TURNOVER INTENTION: A STUDY OF TEACHERS

description: ABSTRACT Purpose: To investigate a theoretical conceptual model for the intention of rotation, analyzing its relationship with well-being at work, psychological capital and intention of rotation. Originality/value: The study contributed to present unpublished aspects and an apparent gap in the theoretical revision of the national literature by the absence of research investigating the relations between psychological capital and intention of rotation. Design/methodology/approach: Research of empirical nature and quantitative approach. We tested four hypotheses regarding the interactions of the variables, using a self-completion questionnaire containing five validated and accurate Brazilian measures. Findings: The hypotheses were confirmed, indicating that teachers have a well-being at work composed of greater satisfactions with colleagues, managers and tasks, and minors with salaries and promotions, medium indexes of involvement with work and affective commitment to the university in which they worked, revealing a low intention of rotation. In the international literature, the concept of psychological capital arises, proposing us future investigations and creating a line of research in Brazil in the measurement of the moderating role of psychological capital in the relations between constructs of organizational behavior. It is essential that other professional categories be studied in the search for evidence about the use of psychological capital as a moderating variable in the relation between the objective dimensions of this study.

title: Morphometric responses and tolerance of pomegranate seedlings irrigated with saline water

description: ABSTRACT Information on the production of seedlings and initial growth of pomegranate irrigated with saline water is scarce in the Brazilian semi-arid region. The objective of this study was to assess the effect of irrigation water salinity levels on the growth and tolerance of pomegranate seedlings. The experiment was conducted in a greenhouse, located at the Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil. A randomized block design with five treatments [electrical conductivities of irrigation water (ECw) of 0.6, 3.0, 6.0, 9.0, 12.0 dS m-1] and five replicates, with three plants per plot, was used. At 120 days after sowing, the following characteristics were evaluated: shoot, root and total lengths (cm); stem diameter (mm), dry mass of stem, leaves, root system and total (g); ratio between root and shoot dry mass; Dickson quality index and salinity tolerance. Growth and dry biomass accumulation in pomegranate seedlings were compromised with increased salinity in irrigation water, but with a lower intensity when subjected up to EC of 6.0 dS m-1. Regarding the criterion of evaluation of tolerance to salinity, pomegranate seedlings were moderately tolerant to salinity.

title: THE TOPPLING OF AN IRRIGATION CENTER PIVOT SUBMITTED TO WIND ACTION EFFECTS

description: ABSTRACT This research aims to improve the study about the stability of truss structures used in pivot irrigation, widely used due to the growing demand for food production, when submitted to wind effects. Specifically, it aims to verify the maximum wind speed supported by an irrigation center pivot structure when submitted to the load effects caused by wind gusts perpendicular to the equipment. In order to determine these forces and their effects on the irrigation equipment, computational numerical investigations were carried out using finite element bar models validated by measuring the natural frequency of the equipment in the field. A span was designed based on the existing standards in Brazil and the dynamic response of the structure was examined under the effects of wind gusts. Models of the Brazilian standard NBR 6123/88 for structures submitted to wind effects were used in this study. The studied irrigation equipment supports wind gusts of up to 115 km/h applied perpendicularly, with a duration of 3 s, before generating toppling.
