title: Exponential smoothing for intermittent demand with demand basis updated more frequently than seasonality factors

description: Abstract This study aims to present an alternative technique of exponential smoothing to estimate the demand for items with intermittent and seasonal demand. The usual technique would aggregate demand periods (months in quarters, for instance) to calculate a seasonality factor for the set of periods. The estimate for the set would be divided by the number of periods comprising it to calculate the demand per period. This technique recalculates the basis and seasonality factor for each set, and provides equal estimates for all periods within the set. The alternative herein presented also recalculates seasonal factors for every set of periods, but recalculates the demand basis for each period, allowing better monitoring of demand behavior. Based on a real-life case, the results obtained by the two techniques mentioned above and by others that do not explicitly consider seasonality were compared: simple moving average, no-seasonality exponential smoothing, Croston’s, and Syntetos-Boylan. The latter two were developed specifically for intermittent demands without seasonality. The techniques that consider seasonality performed better for estimation errors. The suggested technique, in the example, showed less bias, although with somewhat lower accuracy than exponential smoothing with seasonality and period aggregation.

title: Applying the operations strategy construct to rural grain-producing enterprises: a theoretical framework

description: Abstract A firm’s Operations Strategy is responsible for key decisions about the production function activity. Although a significant number of research studies have been conducted about this construct in industrial and service companies, only a few addresses the agricultural sector, specifically the grain production and export industry, which is an important contributor to the Brazilian economy. This study focuses on the operational decisions of grain-producing farms affected by the endogenous and exogenous factors of the grain supply chain. Based on a literature review of the operations strategy, this study aims to present conjectures relating the production decisions of grain-producing enterprises to their Operations Strategies. The results support the applicability of the construct to rural properties. Therefore, future research should address Operations Strategies in agricultural companies and the development/adaptation of tools and management methods applicable to such enterprises.

title: A comparative study of the thermal ranges of three germination criteria of a tropical tree with bioeconomic interest: Carapa surinamensis Miq. (Meliaceae)

description: Abstract Species of the Carapa spp. complex, occurring in the Neotropics, Africa and India, have multiple uses, including timber, with the seed oil being used in phyto-pharmaceutical products and cosmetics. This study aimed to determine the thermal ranges of the germination process, comparing germination criteria used by seed physiologists and seed technologists, and to suggest recommendations for seed quality assessment. Germination was assessed at constant temperatures between 10 ─ 40 °C using three germination criteria: (1) radicle length ≥ 0.5 cm (physiological criterion); (2) epicotyl length ≥ 1 cm; and (3) epicotyl length ≥ 5 cm (criterion for seed quality tests). The base temperature was similar for the three criteria and ranged between 10 ─ 2 °C. The Maguire’s Speed Index indicated 30 °C as most adequate. However, the upper temperature limit differed: for radicle protrusion it was above 40 ºC; and for both epicotyl lengths, it was between 35 ─ 40 °C. Seed coat removal accelerated the germination process of these recalcitrant seeds, and is recommended for seed quality assessment, which allows completion of the germination trial in approximately one month.

title: Relating maturity levels in environmental management by adopting Green Supply Chain Management practices: theoretical convergence and multiple case study

description: Abstract Although the thematic maturity levels of corporate environmental management and the adoption of Green Supply Chain Management (GSCM) practices are consolidating, they have passed through long ways disconnected, given that both have their genesis circumscribed to corporate sustainability. The aim of this qualitative study was to identify the relationship between GSCM practices and maturity levels of environmental management. Literature systematization was carried out dealing with the maturity levels of environmental management and the typology of GSCM practices to reach the study objective. The study was based on multiple cases studies from five different companies inserted in the production chains with high environmental impact: the sector of pesticides, the sector of batteries, and the sector of lead recycling. It was sought the characterization of a logical standard for the adoption of GSCM practices inherent to each maturity level in environmental management. The main results indicate that: at the reactive maturity level in environmental management, organizations adopt specific GSCM practices related to the imposition of legislation; at the preventive level of maturity, organizations adopt GSCM practices related to the return of investments and the reduction of operational costs; and at the proactive level of maturity, organizations tend to adopt practices related to product innovation and environmental communicational processes and practices, aiming to obtain competitive advantages always based on environmental management.

title: Life-history traits of Farlowella hahni (Siluriformes, Loricariidae) in streams of the Ivinhema River Basin, Upper Paraná Basin

description: Abstract Brazilian laws allow the catch of some species as ornamental fish; however, in the absence of biological information, such catch can threaten species conservation. Therefore, this study aimed to offer population and reproductive information about Farlowella hahni in streams of the Ivinhema River Basin, Upper Paraná Basin. To accomplish this, a total of 165 F. hahni individuals were analyzed, including 109 females and 48 males, resulting in an important sex ratio difference from 1:1 (χ 2=19.97; p&lt;0.001), indicating a predominance of females throughout the year. Females reach higher standard length than males. Males presented isometric Length-Weight Relationships, while females have positive allometric growth. Gonadosomatic index presented higher values from October through December. The mean fecundity was 100.3±36.4 of vitellogenic oocytes and was positively correlated with standard length (r=0.51; p=0.01). The data presented herein are the first for this species and suggest a need to carefully manage the F. hahni population, considering its low abundance and fecundity.

title: Knowledge management in conducting simulation projects: a case study in consulting firms

description: Abstract During a simulation project, modelers and customers acquire a greater knowledge of what is being simulated. However, much of this knowledge is lost due to the lack of ways to retain it and due to the lack of discussion about the types of knowledge present in the stages of a simulation project. In this context, this paper aims to present a case study to know how the projects are conducted and to identify the types of knowledge generated during their execution. The case study was performed in simulation consulting firms. Three companies specialized in the simulation were selected: a small one, a medium one, and a large one. It was identified that the four types of knowledge, established by the Nonaka and Takeuchi are present in each step of the simulation project. These results assist modelers in documenting and managing the knowledge and help them to avoid errors.

title: Zika Virus Activity of the Leaf and Branch Extracts of Tontelea micrantha and Its Hexane Extracts Phytochemical Study

description: The new triterpene friedelan-1,3,21-trione, the known compounds friedelan-3-one, 3β-friedelinol, 3,4-seco-friedelan-3-oic acid, 28-hydroxyfriedelan-3-one, friedelan-3-oxo-28-al, friedelan-3,21-dione, 30-hydroxyfriedelan-3-one, a mixture of 30-hydroxyfriedelan-3-one/21α-hydroxyfriedelan-3-one, 21β-hydroxyfriedelan-3-one, gutta-percha, squalene, and a mixture of palmitic/stearic/oleic acids were isolated from the hexane extracts of leaves and branches of T. micrantha. Their chemical structures were established by Fourier transform infrared spectroscopy (FTIR), gas chromatography (GC), 1D/2D nuclear magnetic resonance (NMR) and comparison with the literature data. All compounds were described for T. micrantha and the genus Tontelea for the first time. The branch and leaf extracts displayed anti-Zika virus activity at the lowest tested concentration of 15.6 µg mL-1, mainly virucidal effect, and presented no cytotoxicity to Vero cells. Furthermore, the ethyl acetate and methanolic leaf extracts demonstrated the best activities at the concentration of 31.2 and 15.6 µg mL-1 at the viral adsorption and penetration stages, respectively. These results showed that these extracts may be promising candidates for the Zika virus treatment.

title: Free trade agreements and regional alliances: support from Latin American legislators

description: Abstract The creation of international organizations and the signature of free trade agreements have become common in Latin America. However, few studies have tackled the attitudes of political elites. This work aims to analyze the determinants of support by Latin American legislators for free trade agreements with the US and the EU, and for the Pacific Alliance and ALBA. Results show that ideology, pro-state/market positions, and trustworthiness vis-à-vis Chinese and Russian governments are the main predictors.

title: Anticholinergic toxicity in a one-year-old male following ingestion of Lupinus mutabilis seeds: case report

description: ABSTRACT CONTEXT: The seeds from Lupinus mutabilis Sweet, also called “chocho”, are an important part of the diet in several countries in South America. Prior to consumption, processing is required to remove toxic alkaloids. These alkaloids are known to have pharmacological properties as antiarrhythmics, antimuscarinics and hypoglycemics. CASE REPORT: We report a case in which a one-year-old male initially presented with altered mental status and respiratory distress and subsequently developed symptoms of anticholinergic toxicity, after ingesting a large amount of chocho seeds. CONCLUSION: In spite of going through a difficult clinical condition, the subject evolved favorably through receiving supportive treatment. The seeds from Lupinus mutabilis provide nutritional benefits when consumed, but people need to know their risks when these seeds are consumed without proper preparation.

title: A re-annotation of the Anopheles darlingi mobilome

description: Abstract The mobilome, portion of the genome composed of transposable elements (TEs), of Anopheles darlingi was described together with the genome of this species. Here, this mobilome was revised using similarity and de novo search approaches. A total of 5.6% of the A. darlingi genome is derived of TEs. Class I gypsy and copia were the most abundant superfamilies, corresponding to 22.36% of the mobilome. Non-LTR elements of the R1 and Jockey superfamilies account for 11% of the TEs. Among Class II TEs, the mariner superfamily is the most abundant (16.01%). Approximately 87% of the A. darlingi mobilome consist of short, truncated and/or degenerated copies of TEs. Only three retrotransposons, two belonging to gypsy and one to copia superfamilies, are putatively active elements. Only one Class II element, belonging to the mariner superfamily, is putatively active, having 12 copies in the genome. The TE landscape of A. darlingi is formed primarily by degenerated elements and, therefore, somewhat stable. Future applications of TE-based vectors for genetic transformation of A. darlingi should take into consideration mariner and piggyBac transposons, because full length and putatively active copies of these elements are present in its genome.

title: Impact of untreated dental caries on oral health-related quality of life of children with special health care needs

description: Abstract: The oral health status of children with special health care needs (SHCN) can affect their quality of life wich domains of the Brazilian version of the Early Childohood Oral Health Impact Scale (B-ECOHIS). A cross-sectional study was conducted in children with SHCN (aged 1 to 9 years), who underwent an oral examination for the assessment of dental caries severity. Parents/caregivers answered two questionnaires, one on oral health-related quality of life (OHRQoL) - B-ECOHIS, and one on socioeconomic characteristics. Statistical analyses were performed using the Kolmogorov-Smirnov test, Mann-Whitney U-test, Poisson regression, Point-biserial correlation coefficient, and Cronbach's alpha. A total of 128 children participated in the study and OHRQoL was affected in 68.75% of them. The function domain in the Child Impact Section (CIS) had a higher mean value. Caries severity was associated with worse quality of life (p=0.001). Severe dental caries was associated with a negative impact on the OHRQoL of disabled children and of their families. The impact of untreated dental caries and severity of dental caries was associated with the CIS domains (except for the self-image/social interaction domain).

title: Body Mass Index as a predictor of multimorbidity in the Brazilian population

description: Abstract Overweight is a health risk indicator, but little is known about its influence on the chronic non-communicable diseases (NCD) multimorbidity. The aim of this study was to identify the predictive values and sociodemographic factors associated with Body Mass Index (BMI) as a determinant of the occurrence of NCD multimorbidity in Brazilian men and women. Data from the "Surveillance of risk and protection factors for chronic diseases by telephone survey" -2013 national survey were used. The population was composed of ≥18 year-old individuals and those living in house with a fixed telephone line in the 27 Brazilian’s capitals. The outcome variables were BMI and its respective predictive value for the occurrence of multimorbidity (≥2 NCDs). The exposure was age, marital status and educational level. Inferential statistics included the construction of Receiver Operating Characteristic curves (cutoff point defined by sensibility [Se] and specificity [Sp]) and the association by Poisson Regression, stratified by sex. The values with the best predictive capacity for multimorbidity were 26.7 kg/m2 (Se = 60.9%, Sp = 60.2%) for men and 25.7 kg/m2 (Se = 61.8%, Sp = 61.1%) for women. The predictive multimorbidity value followed the progress of age groups up to 55 to 64 years for both groups. Women with higher educational level showed an inverse association for the presence of the outcome. BMI can be considered a predictor of the occurrence of multimorbidity, and sociodemographic profile associated with this predictive value was advancement age and inversely associated with educational level in women.
