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.

title: Marketing Investment Information: Differentiation Resource or Secret?

description: ABSTRACT Objective: drawing on voluntary disclosure theory, the paper’s main goal was to analyze the main effect of marketing intensity and the moderating role of life cycle on disclosure of marketing investments. Method: the sample includes 89 Brazilian companies listed on B3 stock exchange. We collected financial data from two sources, such as Economatica platform and in the explanatory notes and management report from the companies, which we coded through content analysis. We merged these two datasets and analyzed it using multiple linear regression. Results: both the marketing intensity and the life cycle of companies have effects on disclosure of marketing investments. In addition, the birth and growth phases moderate the main effect of marketing intensity, reducing the level of disclosure. This moderation is identified especially in disclosures of qualitative information. Conclusions: the findings support the voluntary disclosure theory based on arguments of judgment-based disclosure. Outcomes showed that when there is a high intensity of marketing investments, disclosure of marketing investments is managed by moving from the status of secrecy in companies in the birth and growth phases of life cycle to the status of differentiation resource in companies in the maturity phase of life cycle.

title: THE CONSTRUCTION OF THE TEACHER’S ACTION BY ENGLISH TEACHERS FOR CHILDREN: A VIEW TO TEACHING AS LABOR

description: ABSTRACT This article aims at recognizing the activity of teaching English as a Foreign Language to children and the dimensions of the teacher action based on the theoretical and methodological principles of the Sociodiscursive Interactionism (BRONCKART, 1999-2003, 2007, 2008). The data were resumed from two case studies from 2013/2014 and 2015/2016. The theoretical input examines the existing gap in the Humanities curriculum education regarding teaching English to children in Brazil (ROCHA, TONELLI; SILVA, 2010; TONELLI; FERREIRO; BELO-CORDEIRO, 2017; SANTOS; BENEDETTI, 2009), on behalf of children’s particularities (VYGOTSKY, 1998), and education for a critical citizenship (ROCHA; BASSO, 2007; PESSOA; BORELLI, 2011). Teaching as labor and how the teacher’s action is shaped (FAῘTA, 2004; AMIGUES, 2004; MACHADO, 2004) anchor the analyses of the teachers’ reflections. Data were generated through interviews and a reflexive session based upon a drawing. Data analyses reinforced the relevance of teacher education targeted at the specific traces of the English to children teaching education activity, composed of every dimension of the human being. It also revealed teachers’ beliefs about teaching EFLC in public schools as well as traces of linguistic imperialism influence.

title: Anaerobic co-digestion of swine manure and forage at two harvesting ages

description: ABSTRACT: The co-digestion of swine manure with vegetable waste is an alternative that can increase the production of biogas and methane generated by the isolated digestion of manure. However, recommendations that are based on the best ratio between manure and forage, as well as the age of harvest, are still scarce in the literature. This study was conducted to evaluate inclusions (0, 25, 50, 75 and 100%) of the total solids (TS) of Elephant grass (Pennisetum purpureum Schum) harvested at two ages medium age (MA) at 45 days of growth and advanced age (AA) at 90 days in co-digestion with swine manure, using an entirely randomized design in a 5x2 factorial scheme. Batch digesters were used and biogas production was monitored for 12 weeks. There was influence of forage age (P &lt;0.05) on the degradation of solids and neutral detergent fiber, with higher values for the substrates containing MA forage. The highest CH4 yields were obtained by the substrates containing MA forage in the inclusion of 27.7 and 31.6%, being 253.7 and 222.2 L of CH4 per Kg of total or volatile solids. The age of the forages influenced the onset and persistence of biogas production, being advantageous only in the inclusion of 25% of MA forage. The AA forage inclusion is not recommended for co-digestion with swine manure.

title: Factors associated with the purchase of family farming products for national school feeding program in Minas Gerais in 2017, Brazil

description: ABSTRACT: The National School Feeding Program (in abbreviated Portuguese: PNAE) states that ≥30% of the amount transferred by the National Fund for Education Development (in abbreviated Portuguese: FNDE) to the executing entities should be used to purchase products made from Family Farming (FF). This study aimed to identify the municipal characteristics associated with the compliance of the municipalities of Minas Gerais (MG) to this target in 2017. For this, data on municipal purchases of FF for the PNAE were obtained from the FNDE’s website. Sociodemographic, economic, and agricultural characteristics of the municipalities were associated with compliance to the PNAE’s goal. Approximately half (55.07%) of the municipalities complied with the FF purchase target, wherein carrying out programs or actions to encourage organic agriculture (29.8% vs. 22.6%, p=0.018) were associated with a greater compliance to this target, presenting the official rural union registration (76.4% vs. 68.8%, p=0.026) and the Municipal Inspection Service: (35.6% vs. 29.1%, p=0.048). Overall, a low compliance to the goal was observed in MG municipalities, and associations between certain agricultural management characteristics and goal fulfillment were evidenced.

title: Brain-derived Neurotropic factor (BDNF) mediates the protective effect of Cucurbita pepo L. on salivary glands of rats exposed to chronic stress evident by structural, biochemical and molecular study

description: Abstract Acute and chronic stresses affect the salivary glands, representing the source of plasma BDNF during stressful conditions. Pumpkin is a medicinal plant with an evident antioxidant, anti-inflammatory and potential antidepressant effects. Objective To assess the structural and biochemical effects induced by exposure to chronic unpredictable mild stress (CUMS) on salivary glands of albino rats, and to evaluate the role of pumpkin extract (Pump) in ameliorating this effect. Methodology Four groups (n=10 each) of male albino rats were included in this study: the control, CUMS, Fluoxetine-treated and Pump-treated. The corticosterone, the pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), and the oxidant/antioxidant profile were all assessed in the serum. The level of BDNF mRNA was measured in the salivary glands using qRT-PCR. Histopathological changes of the salivary glands were also assessed. Results The depressive-like status was confirmed behaviorally and biochemically. Exposure to CUMS significantly up-regulated (p&lt;0.001) the level of serum corticosterone. CUMS induced degenerative changes in the secretory and ductal elements of the salivary glands evident by increased apoptosis. Both Fluoxetine and Pumpkin significantly up-regulated (p&lt;0.001) BDNF expression in the salivary glands and ameliorated the CUMS-induced histopathological and biochemical alterations in the salivary glands. Pumpkin significantly (p&lt;0.001) increased the serum levels of antioxidant enzymes SOD, GPX and CAT, and reduced the serum levels of the pro-inflammatory cytokines TNF-α, IL-6. Conclusion Pumpkin ameliorates the depressive-like status induced in rats following exposure to chronic stress through exerting a promising anti-inflammatory, antioxidant and anti-depressant-like effects. The pumpkin, subsequently, improved stress-induced structural changes in the salivary glands that might be due to up-regulation of BDNF expression in the glands.

title: Approaches to environmental issues in Physics teacher education programs

description: Abstract In this study we aim to investigate the possibilities for approaching environmental issues in Physics Teacher Education programs. Inspired by Content Analysis procedures, we analyzed the curricula of 15 Physics Teacher Education programs, offered by public Higher Education Institutions in the state of São Paulo, Brazil. In this analysis, we selected 70 required and 8 elective courses, organized into a set that explores the insertion of environmental issues in elementary education and aims to prepare the teacher to approach the topic in physics classes; and another set of courses that analyze and describe the environment, natural phenomena and environmental impacts caused by technological development. All analyzed programs have at least one course that addresses aspects of the environmental issues and, because they propose diverse approaches, we highlight different possibilities dealing with the topic in the Physics Teacher Education.
