title: Leverage and investment opportunities: the effect on high growth firms

description: ABSTRACT The objective of this paper is to investigate if the high growth of a firm results in a reduction in its debt levels. This is expected to happen for firms that experience a positive idiosyncratic shock to their growth opportunities, which would affect their cash flow and profitability. Although the relationship between growth opportunities (e.g., Tobin’s Q) and capital structure has already been widely discussed from a conceptual viewpoint, there are still important empirical gaps, particularly due to the endogeneity of the first variable. This paper seeks to minimize these problems by operationalizing the concept of idiosyncratic technological shocks. This issue is relevant because the negative relationship between growth and leverage may indicate that for the most efficient companies there will be a reduction in bankruptcy cost and a reduction in agency costs for the least efficient companies. This paper contributes to the development of studies in the area by demonstrating the inverse relationship between growth and leverage, with the model and the variable that represents the positive shocks experienced by companies. The dynamic panel method enables an analysis of the variation in debt in relation to the variation in value using the first differences and controlling the lagged debt effect. To apply the model, we used data from Brazilian companies, covering 1995 to 2016. The main results show that the greater the ratio between the firm’s growth opportunities and its industry growth opportunities, the lower its leverage indicators. The complementary results suggest that less leveraged firms have this negative relationship to an even stronger degree.

title: Care complexity in hospitalized elderly according to cognitive performance

description: ABSTRACT Objective: to investigate possible differences in care complexity, functional performance and biopsychosocial and health system aspects among hospitalized elderly with or without cognitive decline. Method: quantitative, cross-sectional and analytical study in which was used the INTERMED method and cognitive and functional screening scales. We investigated 384 elderly patients admitted to a medical and surgical clinic of a University Hospital located in São Paulo/SP. Results: cognitive decline was present in 40.1% of the sample, most of them were longer-lived elderly individuals with less schooling and income, more dependent in activities of daily living and had greater vulnerability in different domains of INTERMED. After adjustments, the elderly with cognitive decline presented greater vulnerability in the psychological domain. Conclusion: the relationship between cognitive decline and psychological vulnerability highlights the need to adopt long-term care based on involvement of the family, health team and different services, thereby maximizing the quality of care.

title: Productivity and crude protein concentration of Tifton 85 pasture-based mixed with pinto peanut

description: ABSTRACT Mixed pasture grass-legume systems balance forage supply and minimize environmental impacts by reducing the need for nitrogen fertilization. Pinto peanut (Arachis pintoi Krap. and Greg. “Amarillo”) has several traits that are suitable for mixed pastures but have not yet been adequately explored. The aim of this study was to evaluate a mixture of Tifton 85 bermudagrass (Cynodon dactylon) and pinto peanut and evaluate forage yield, crude protein, and stocking density. A two-year study of three grazing systems was used with the following treatment combinations: (a) Tifton 85 (T) + 100 kg N ha-1 yr-1 + pinto peanut (T + PP+100); (b) T + 100 kg N ha-1 yr-1 (T + 100; control, pure grass); and (c) T + 200 kg N ha-1 yr-1 (T + 200; positive control, pure grass). In this study, forage yield, pasture characteristics and responses of lactating cows were evaluated. The experimental design was completely randomized with three treatments (grazing systems), three replicates (paddocks), and repeated measures (grazing cycles within seasons). Forage accumulation, crude protein concentration, and stocking rate were 15.1; 11.3 and 14.1 t DM ha-1 yr-1; 17%, 16%, and 17%; and 5.3; 4.9 and 6.1 AU ha-1 day-1, respectively. The grass-legume system yielded the best results.

title: International VaR approach: Backtesting for different capital markets

description: ABSTRACT This article aims to compare distinct metrics of the value at risk (VaR), differing from prior studies with respect about compare three asset categories belonging to seven countries. Since VaR inception, several approaches were developed to improve the loss estimation accuracy. However, there is hardly a universal consensus on which approach is the most appropriate, since VaR depends on statistical properties of the target asset and the market in which it is traded. It is relevant to compare the results obtained not only among the assets, but also among the markets in which they are traded, considering their specifics properties to verify if there is any pattern of the methods for the data. Considering the three asset categories, the semiparametric and non-parametric models obtained the lowest rejections number. It was also found that the models tested were not effective for the estimation of exchange rate VaR, which may be due to more relevant risks than the market in it asset price formation. Five models belonging to the parametric, semiparametric, and non-parametric approaches were tested. The analyses were divided in two, aiming to test the VaRs performances in distinct economic cycles; the first analyses considered a 1,000 days estimation window, while the second one considered a 252 days estimation window. To validated the results statistically, were applied the Kupiec and the Christoffersen tests. The results show that the conditional VaR and historical simulation have the best performance to estimate VaR. Comparing the markets, Chinese assets were the ones with the highest average number of tests rejections, which can be a consequence of its closed economy. Finally, it was found that shorter estimation window tends to perform better for high volatility assets, while longer window tends for lower volatility assets.

title: Effects of multicomponent brine on functional and technological properties of camel meat raw materials and finished products

description: Abstract The purpose of this study is a theoretical rationale and practical implementation of the technology of the production of national meat products with increased food and biological value based on a differentiated use of camel meat cuts. To achieve this aim the following tasks were specified: to investigate the effects of herbal additives to the brine and vegetable-protein compositions on the structural, mechanical and consumer properties of camel meat and finished products, to investigate the effects of a multicomponent brine on the biochemical, diffusion and osmotic processes during camel meat salting; to justify an optimal composition of a multicomponent brine for camel meat salting and the amount of brine to be injected into the meat. During the study, scientific concepts, principles and integrated approaches to the development of food products with specified properties were used based on standard and special methods for data collection and analysis, as well as systematization of the results. To carry out a comprehensive assessment of the quality of raw materials and finished products, conventional, standard and special methods for organoleptic and physicochemical parameters, nutritional value and safety, were used. The results of the study showed that the use of herbal additives to the composition of the injected brine was aimed at an increase of the cohesion-adhesion processes in the meat system.

title: Geohelminths in the soil of the Laguna dos Patos in Rio Grande do Sul state, Brazil

description: Abstract This study aimed at examining the prevalence of eggs and larvae of parasites – that may cause diseases to humans and other animals – in the soil of public squares located on the shore of Laranjal beaches, in the Laguna dos Patos, in Pelotas, Rio Grande do Sul state, Brazil. Four fieldwork trips – one per season – were taken to collect samples on six squares built on the shore of these beaches. Five samples of soil were collected on every square on every fieldwork trip. The material was processed by Caldwell & Caldwell’s technique. Four squares (66.7%) were positive for helminth eggs and sample positivity was 8.3% (10). Toxocara spp. and Ancylostoma spp. were the main genera found in these places. Even though prevalence was lower than the one observed by other studies which were carried out in the area, helminths with zoonotic potential were found in the soil of the squares. It should be highlighted that measures to control dogs in these areas must be implemented and public policies must be put forth to make pets’ owners and beach goers aware of the need to mitigate environmental contamination.

title: Characterization of tropical viticulture in the fluminense north and northwest regions

description: Abstract Viticulture is a recent activity in Rio de Janeiro, which has been well adapted to the edaphoclimatic conditions of the north and northwest regions of Rio de Janeiro. The aim of this study was to characterize the main socioenvironmental and technological aspects of grape production in these regions. Data were collected in 2017 and 2018, from the application of questionnaires to 16 grape producers in the regions, for descriptive statistical analysis and preparation of tables and graphs. In both regions small producers are the main investors. Most of them do not participate in associations and have technical assistance in particular. The region has favorable edaphoclimatic characteristics, mainly for the cultivation of rustic grapes, predominantly cultivar ‘Niagara Rosada’. Disease control is carried out in a preventive manner, with eleven applications ranging from sprouting to days before harvest. The regions present more than one harvest per year, having supply in the season and national off season. These results may support information on the characteristics of Rio de Janeiro’s viticulture, direct incentives for the activity and serve as a basis for further research, such as planning programs for grape production areas.

title: Causes of cost overrun and financial impact on public works from risk management perspective

description: Abstract This paper aims to analyse the main causes for contracting additional services in public construction works, from a risk management perspective. A systematic literature review led to a new categorisation of the causes of cost overrun based on risk taxonomy. The field study involved an analysis of contracts for new and completed works at a public higher education institution. The Iramuteq software performed a lexical analysis of the justifications for the additions. The categorisation of the causes resulting from the literature review supported the definition of each risk category. The financial impact for each risk category was measured by quantitative analysis. The results indicate that the highest risk index corresponds to the project category, with 53% of addition frequency and 56% of financial impact. The contributions of this study involve the proposed model for analysis of the causes of cost overrun based on risk taxonomy and the association of lexical and documentary analyses to reduce subjectivity and improve the risk mitigation process.

title: Method for location-based production planning and control supported by BIM

description: Abstract The location-based approach for production planning and control has the advantage of making explicit the workflow throughout the production units, allowing to make a connection to the Last Planner System (LPS) and 4D BIM models. However, there are still some knowledge gaps, in both practice and research, regarding the implementation of this approach. Those gaps are mainly related to the application concepts and principles of the lean production philosophy, and their interaction with BIM functionalities. Indeed, it is necessary to develop studies not only on planning and control methods that consider the partially repetitive nature of construction activities, but also on the aspects related to work and product flow management. The aim of this study is to propose a Location-Based Planning and Control method supported by BIM and explore its interface with LPS. Design Science Research was the methodological approach adopted in this investigation and two empirical studies were carried out in real estate companies. The main contributions of the proposed method are related to the tools adopted, which can potentially contribute to improve the quality of information, mainly related to workflows, and to provide support to collaborative decision-making.
