title: Antecedents of Commitment to Budgetary Goals

description: ABSTRACT Objective: this study analyzes the interactions between budgetary participation, motivation at work (intrinsic and extrinsic), and commitment to budgetary goals. Methods: a survey was carried out with 131 intermediate level managers from different organizational areas of companies classified among the best and biggest companies in Brazil. Results: the results of modeling structural equations indicate that intrinsic and extrinsic motivations have different roles in their interactions with budgetary participation and commitment to goals. And their involvement in the budgetary process reveals behavioral and motivational effects. Conclusions: it is concluded that participation in the budgetary process can positively reflect on managerial performance, insofar as it is able to trigger intrinsic motivational effect and favor behaviors aimed at the commitment to budgetary goals.

title: Microflora communities which can convert digested sludge to biogas

description: In the present study, we developed several microflora communities that utilize digested sludge (DS), the recalcitrant waste product of anaerobic digestion, as a substrate for biogas production with the aim of their future application to DS recycling. Strict enrichment with DS as the sole nutrient source was introduced to culture microbes from soil and herbivore dung samples; microflora communities promoting stable levels of biogas production were obtained. The average methane and hydrogen yield from soil-derived microflora were 4.86 and 0.94 ml per 1.0 g DS, respectively. Notably, two microflora communities enriched from a riverbank sediment produced 20.79 ml and 14.10 ml methane from 1.0 g DS. By contrast, the methane and hydrogen yield for herbivore dung-derived microfloras were on average 1.31 ml and 1.87 ml per 1.0 g DS, respectively. Potent hydrogen-biogas producers were obtained from rabbit (4.12 ml per 1.0 g DS), goat (3.16 ml per 1.0 g DS), and sheep dung (2.52 ml per 1.0 g DS). The cultured microflora communities included representatives from the eubacterial genera, <i>Clostridiaceae</i> and <i>Eubacteriaceae</i> together with several anaerobic genera. <i>Pseudomonas</i> spp. are found in the riverbank sediment-derived microfloras, suggesting that the floras employ syntrophic acetate oxidation and hydrogentrophic methanogenesis (SAO-HM) pathway for methane production. The methanogenic microflora communities were dominated by bacteria from the <i>Methanobacteriaceae</i> family and unclassified archaea. Moreover, ascomycetous fungi and protists were found, implying that they act as oxygen scavengers and bacterial grazers, respectively. Enzymatic analysis suggested that the microfloras hydrolyze DS via cellulase, chitinase, and protease activities.

title: Hypomagnesemia in beef cattle from the central region of Argentina: retrospective study

description: ABSTRACT: Hypomagnesaemia (grass tetany) is a metabolic disorder of ruminants due to a reduced dietary intake of magnesium (primary deficiency), incorrect digestibility or associated metabolic factors reducing Mg intake (secondary deficiency). Grass tetany is a production disease responsible for important economic losses in beef herds from Argentina. Several factors influence the development of grass tetany in cattle, including physiological status, weather, soil and forage. This research described a retrospective analysis over the past 20 years, revising the cases of beef cattle clinical hypomagnesaemia registered at the Veterinary Diagnostic Service in INTA Balcarce, Argentina.

title: GENDER PERCEPTION BY ACOUSTIC SPEECH CHARACTERISTICS AND PITCH VARIABILITY

description: ABSTRACT The research aimed at phoneticaly examining the speech of 14 men, 7 who declared themselves to be gay and 7 self-declared heterosexuals. The audios of these men´s voices were submitted to tests of perception and judged by evaluating listening lay judges. The theoretical assumptions of Variationist Sociolinguistics by Labov (2008 [1972]) and Eckert (1989, 1997, 2000, 2003, 2005, 2012; ECKERT; MCCONNELL-GINET, 2010) and Speech Perception, carried out by Gaudio (1994); Smyth, Jacobs and Rogers (2003); Levon (2007); Campbell-Kibler (2011), among others, were used. Significant greater averages of pitch variability among gay informants were also verified. In most aspects, the averages of homosexual informants were closer to the averages of gay informants participating in English-language surveys than the averages presented by the heterosexual informants. Thus, due to the similarities of results found in some surveys, it seems acceptable to affirm that there are some universal typical aspects that characterize a “gay speech”.

title: Long-term Financing: Exploring the Recent Advances in the Brazilian Bond Market

description: ABSTRACT Context: in Brazil, there was an expansion of private funding via bond issuances, especially since 2017. Before that period, the sources of long-term financing were concentrated on public funding. Objective: this study aims to explore the main factors that could have positively affect Brazilian bond market and if it would be possible to improve project financing through this debt instruments. Methods: using mixed methods with econometric tests and qualitative interview analysis, this study assesses which were the factors that supported this growth and if there is any difference across industries. Results: we found that a change in the market trend has indeed happened around 2017, and it was more pronounced in specific industries such as electricity. Interviewees suggested that increases in demand (possibly triggered by the reduction of public sources of funding and the fall in local interest rates) could be the main factors that supported this change in trend. Conclusions: therefore, this study reinforces the importance of local market conditions and government policies affecting the relative attractiveness of private versus public sources of corporate investment.

title: Lipid profile of subcutaneous fat, growth performance, and carcass characteristics of gilts fed with diets supplemented with ractopamine, organic chromium or subjected to energetic feed restriction

description: ABSTRACT: This study identified the effects of dietary supplementation with ractopamine, chromium picolinate, chromium yeast, or an energetic feed restriction on the growth performance and lipid profile of subcutaneous fat, in late finishing gilts. Twenty genetically similar gilts with initial body weight of 105.35 ± 4.77 kg and a final body weight of 131.37 ± 5.58 kg were distributed in a completely randomized block design with five treatments (control; ractopamine: 20 ppm; chromium picolinate: 0.48 ppm; chromium yeast: 0.80 ppm; and energetic feed restriction: -150 kcal kg-1 of metabolizable energy), with four replicates of one animal each. The experimental diets were isonutritives, except for the metabolizable energy level of the diet fed to the group subjected to energy restriction. There were no effects on the growth performance and carcass characteristics. Ractopamine and organic chromium (picolinate and yeast) supplementation increased the concentration of total polyunsaturated fatty acid. The proportion of α-linolenic fatty acids were higher when the diets were supplemented with ractopamine or chromium yeast. The energy restriction increased the n-6:n-3 ratio and reduced α-linolenic acid concentration. Therefore, ractopamine, chromium picolinate, chromium yeast supplementation, and energetic feed restriction did not affect the growth performance or carcass characteristics but altered the lipid profile of subcutaneous fat in finishing gilts. Ractopamine and organic chromium supplementation increased PUFA in the fat of finishing female pigs.

title: FOXE1 polymorphisms and chronic exposure to nitrates in drinking water cause metabolic dysfunction, thyroid abnormalities, and genotoxic damage in women

description: Abstract Nitrates in drinking water has been associated to adverse health effects, including changes in glucose and lipid levels, thyroid hormone imbalance and adverse reproductive effects. We analyzed metabolic and thyroid hormone alterations and genotoxic damage in women with chronic exposure to nitrates in drinking water. The concentration of nitrates in drinking water was quantified and according to this parameter, participants were divided into three exposure scenarios. Blood and urine samples were collected from 420 women living in Durango, Mexico and biomarkers were determined. We found nitrates concentrations in drinking water above the permissible limit (&gt;50 mg/L), and an increase in the percentage of methemoglobin (p=0.0001), nitrite in blood plasma and urine (p=0.0001), glucose (p=0.0001), total cholesterol (p=0.001), LDL (p=0.001) and triglycerides (p=0.0001). We also found alterations in TSH (p=0.01), fT3 (p=0.0003), T4T (p=0.01) and fT4 (p=0.0004) hormones. Frequency of subclinical hypothyroidism was 8.33%; differences in FOXE1 (rs965513, rs1867277) genotypes distribution were found and both polymorphisms were associated with a decrease in TSH. A high percentage of micronucleus in binucleate lymphocyte cells was found (35%, p=0.0001). In conclusion, the chronic exposure to nitrates in water for human consumption caused metabolic and hormonal alterations and genotoxic damage in women.

title: Biometry in Umbu fruits from the semi-arid region of Paraiba

description: Abstract Umbu fruits from four municipalities of Paraíba were morphologically characterized in order to identify promising genotypes for fresh consumption and agro-industrial use. We used 400 fruits from parent plants located in São Vicente do Seridó, Queimadas, Boqueirão, and Cabaceiras and 40 commercial fruits from two open fairs in Campina Grande, PB. The experimental unit consisted of ten fruits. The fruits were analyzed for total mass (MTF), length (LC), diameter (DF), fresh matter (MMF), yield (RF), and presence of hairs. In the endocarps, mass (ME), length (CE), diameter (DE), and width (LE) were the evaluated parameters. A completely randomized design was adopted, the data were subjected to variance analysis, and the means were compared by the Tukey test and principal component analysis. The fruits from Queimadas and São Vicente do Seridó showed the best morphological characters with regard to mass, length, diameter, fresh matter, and fruit yield, and were the most promising for agro-industrial commercialization. The fruits from Boqueirão showed the highest endocarp mass. Most fruits showed hairs on the peel, except the commercial ones. Four groups of municipalities were formed, with the fruits from Queimadas showing the largest size, while the fruits from São Vicente de Seridó and Soledade showed the highest yield.

title: Supplementary Material for: Brain Imaging Features Associated with 20-Year Cognitive Decline in a Community-Based Multiethnic Cohort Without Dementia

description: Introduction: This study aimed to characterize the association of cognitive decline starting in midlife with brain pathology in late-life in the absence of dementia. Methods: Non-demented Atherosclerosis Risk in Communities (ARIC) participants with brain imaging, all cognitive factor scores (CFS), and non-missing covariates were included. CFS were collected at three visits across 21 years (1990-2013) (short-term cognitive change [1990-1996], long-term cognitive change [1990-2013]), and brain magnetic resonance imaging (MRI) and florbetapir positron emission tomography (PET) imaging were collected in 2011-13 (PET subset n=327). Outcomes of interest were total and regional brain volumes (cm3), log2(white matter hyperintensity volume), white matter integrity (fractional anisotropy, mean diffusivity), ≥1 lacunar infarct (3-20 mm), and elevated brain -amyloid (SUVR &gt;1.2). Multivariable linear/logistic regression related outcomes to CFS slopes after adjusting for demographics and total intracranial volume. Results: At baseline, the 1734 participants had a mean (SD) age of 55 (5.2) years, were 60% female, and 26% Black. After adjustment, a 1-SD larger long-term decline in CFS was associated with a smaller relative total brain volume by 1.2% [95%CI: 1.0, 1.5], a smaller relative temporal lobe meta region volume by 1.9% [1.5, 2.3], a 13% [9, 17] larger volume of white matter hyperintensities, a 1.3-fold [1.2, 1.4] higher odds of having ≥1 lacune, and 1.7-fold [1.3, 2.2] higher odds of elevated brain -amyloid deposition, and worse white matter integrity. Some long-term associations were also found for midlife short-term declines in CFS. Conclusions: This study provides evidence that starting in midlife, short-term and long-term declines in cognition are associated with multiple deleterious late-life differences in non-demented brains.
