title: The Negative Evidence Hypothesis: The Acquisition of the Double-Object Construction by Brazilian-Portuguese English Bilinguals

description: Abstract: This study aims to add to the body of evidence regarding the linguistic structures that seem to be more challenging in L2 acquisition than in L1 acquisition (DeKeyser, 2005; Ellis, 2008; Inagaki, 2001; Slabakova, 2014; Sorace, 2011). The Negative Evidence Hypothesis (NEH) (Oliveira, 2016) predicts that bilinguals are less sensitive than native speakers to violations resulted from the overgeneralization of an L2-specific rule. We tested this hypothesis by analyzing the behavior of Brazilian Portuguese-English bilinguals with different profiles towards the double-object construction in English with unlicensed verbs in two acceptability judgment tasks. The results corroborate the NEH by conveying that bilinguals gain sensitivity as they become more proficient, yet, the data suggest that not even when immersed in the L2, they become as sensitive as native speakers.

title: Riparian vegetation structure and soil variables in Pandeiros river, Brazil

description: Abstract This study analyzed the floristic, structural variations and their relationships with soil variables in two stretches of riparian vegetation in an ecotonal region between savanna and semiarid zones. We following the hypothesis of despite the proximity between the sampled areas, soil conditions are distinct and lead to changes in structure and composition of the vegetation. This study was development at EPA of Pandeiros River, Minas Gerais, where we allocated 140 plots of 10 × 10 m (100 m2), with 10 m distance between plots, in two areas of riparian vegetation, named Larga and São Domingos (70 plots in each area), where we conducted the phytosociological survey and collected soil samples. In total, 751 arboreal individuals were sampled, distributed in 89 species and 35 botanical families. The areas differed strongly in structure and species composition, and showed floristic peculiarities and influence of surrounding vegetation. Despite of low distance between the sampled areas, these are singular environments influenced by different soils, by the mixed composition of the ecotonal area and the anthropogenic impacts to which they are exposed.

title: Phenological study of populations of Cnidoscolus quercifolius in the Western Seridó, Paraiba state, Brazil

description: Abstract The phenological patterns of two populations of Cnidoscolus quercifolius were evaluated in the western Seridó region of Paraiba state, Brazil, from March 2009 to February 2011, with data collected monthly. The evaluations have addressed the quantitative method of analysis that represents the activity indices for both populations growing seasons (fall and sprout) and reproductive (flowering and fruiting), and also studied the intensity index Borchert, who evaluated the flow leaves. The stages were evaluated with respect to variations in rainfall, water potential of plant and quantum efficiency of photosystem II. The bud in the two populations occurred in the late dry season and transition into the rainy season, with peak leafing in January and November 2010 and was negatively correlated with rainfall (rs = -0.54 p &lt;0.05). Leaf fall showed the peak phase in October 2009 and 2010, showing a direct relationship with water potential and photosynthetic quantum efficiency. The flowering and fruiting had greater synchrony in the seasonal rainy period, fruit set was positively correlated with precipitation values during the study period (rs = 0.56 p &lt;0.05). The phenological events of C. quercifolius show marked seasonality in relation to precipitation, water potential and the quantum efficiency of photosystem II.

title: Health aspects and ideal temperature for germination of peanut seeds

description: Abstract: This study was performed to identify the best temperatures for germinating peanut seeds with fungi on a paper substrate. Eleven seed lots from the cultivars IAC-886 and IAC-503 were selected with different levels of fungi. Two of these seed lots with a high rate of Aspergillus spp., Penicillium sp., and Rhizopus sp., as detected by the blotter test method, were used for selecting a fungicide for seed treatment. Considering the active ingredients evaluated, thiram, at the rate of 300 g of commercial product per 100 kg of seeds, was most efficient in controlling fungi, preventing their interference in germination. All the seed lots, treated with this product or not, were subjected to the germination test on rolls of paper at the temperatures of 25 °C, 30 °C, 35 °C, 20-30 °C, 20-35 °C, 25-30 °C, and 25-35 °C. Alternating temperatures of 20-35 °C, 20-30 °C, and 25-30 °C led to higher germination of peanut seeds, treated with fungicides or not. Constant temperatures are not recommended, because they are more favorable to the development of fungi associated with these seeds than to the germination process, thus underestimating the germination potential of the seeds subjected to the test.

title: Viability of Simira gardneriana M.R. Barbosa & Peixoto seeds by the tetrazolium test

description: Abstract: Ecoregion Caatinga presents a great diversity of species with potential for exploitation. Among them 'pereiro-vermelho' (Simira gardneriana M.R. Barbosa & Peixoto) stands out for its importance in timber and forestry activities. Its seeds germinate slowly. Therefore, the use of tetrazolium test to estimate viability becomes essential when quick answers on seeds quality are wanted. This study has aimed to establish the best concentration of tetrazolium solution and the coloration period for assessing the viability of Simira gardneriana seeds. Initially, seeds were subjected to pre-wetting between paper sheets for 144 hours at 30 °C. Subsequently, the endosperm portion containing the embryo was immersed at four concentrations of tetrazolium solution (0.075, 0.1, 0.5 and 1.0%) and three coloration periods (2, 4 and 6 hours) in the dark under the temperature of 30 °C and another one at 35 °C. The percentage of viable seeds was compared with the results obtained in the germination test conducted on paper substrate at 30 °C in four replicates of 25 seeds. Tetrazolium test was efficient to estimate the viability of S. gardneriana seed and the concentration of 0.075% for six hours at 35 °C was the best condition.

title: Knowledge transferences and appropriations: Friedrich Bieri and the mathematic to the primary school

description: Starting from the analyses of Friedrich Bieri (1844-1924) work, a Swiss who immigrated to Brazil in the 19th century, we identified knowledge appropriation produced in German speaking countries in the Brazilian teaching. This study brings up Bieri's profile as well as reports the knowledge transference process occurred and its role in the country of Rio Grande do Sul. Bieri's work analyses allowed concluding that the author, besides being one of the precursors of didactics books for Teutonic schools production, also adopted a German pedagogical proposal adapted to the local context and influenced by Grube's method and its reformulation by Egger.

title: Sequence stratigraphy of fluvial to shallow-marine deposits: The case of the early Permian Rio Bonito Formation, Paraná Basin, southernmost Brazil

description: Abstract This study presents new sedimentology data and attempts to understand coastal processes, sedimentary dynamics and stratigraphic patterns of the Rio Bonito Formation (early Permian) in Paraná Basin, southern Brazil. The study was performed based on the description of five cores, located in a small-scale area - São Gabriel City - in Rio Grande do Sul State, southern Brazil. Eighteen facies were described and grouped into nine facies associations. Later, these facies associations were then grouped into three depositional systems: fluvial, tide-dominated estuary and wave-dominated shallow-marine depositional systems. A paleoenvironmental evolution is proposed using three block diagrams showing the paleoenvironmental stage (S1, S2, and S3). S1 contains the oldest part of the sedimentary record with predominance of fluvial system deposits, S2 comprises dominantly estuarine system deposits, and S3 is mostly composed of shallow-marine deposits. Stratigraphic framework showed a general retrogradacional tendency, with thickness variations along the systems tracts that allowed for the construction of a curve of accommodation changes to the Rio Bonito Formation in the region of São Gabriel during the early Permian. This study contributes to a better understanding of the fluvial discharges, tidal and oscillatory (wave) currents and their interactions and dominances along stratigraphic records of coastal deposits.

title: The effects of financial leverage and debt maturity on the investments of Brazilian electric sector companies

description: Abstract Purpose: This research aimed to verify how companies of the electric energy segment choose levels of financial leverage and debt maturity in order to alleviate the underinvestment problem. Design/methodology/approach: A multiple linear regression was carried out in a dynamic panel model to verify the relevance of these and other variables to the companies’ investments. Findings: The explanatory variable of investments carried out in the previous year was significant in the regressions, with a positive sign as expected. The financial leverage variable was significant and negative. The investments made by the companies are negatively related to indebtedness. Originality/value: It was identified that the maturity of debts of companies with low growth opportunities shows a negative relationship with the level of investment. Thus, in the electricity sector, reducing debt maturity can be considered as a substitute for reducing indebtedness in controlling underinvestment. Due to the relevance of this sector to the economy and the need for constant investments in it, understanding its financing dynamics provides an important contribution either to researchers or to managers of this industry.

title: Anatomical structure of vegetative organs of Blutaparon vermiculare (Amaranthaceae) y Funastrum glaucum (Apocynaceae), species growing in the Venezuelan coastal zones

description: Abstract Blutaparon vermiculare and Funastrum glaucum grow in sandy soils with low nutrients availability and low water retention capacity, also influenced by salinity, high radiation and strong winds. The aim of this study was the anatomical characterization of vegetative organs and distinguishing characters that could be linked to habitat conditions. Roots, stems and leaves were collected and they were processed following the standard methodology for mounts observable with an optical microscope. In B. vermiculare, the roots are tri or tetrarchs with bulky cortical parenchyma cells; young stems have a typical eustele and a typical secondary vascular ring, but others lateral meristems are added; the leaves of this species are epistomatics, bifacial with abaxial aquifer parenchyma and mesophyll with stellate cells around the vascular bundles. Funastrum glaucum has diarch roots; in their young stems is evident hypodermis, palisade parenchyma and the primary vascular tissue organized in a ring with a very narrow parenchimatic radio; in secondary structure, vascular cambium with unequal activity; the leaves are fleshy, anphystomatics and bifacials with papillose abaxial epidermis. B. vermiculare is distinguished by the abundance of crystals in leaves and stems, and F. glaucum by their important starchy reservation in caules. The features that ensure their survival were discussed, among they distinguish the following: developed protective tissues, presence of water reservoir, Kranz anatomy, variants in vascular cambium activity.

title: Public Policies to Promote Reading in Brazil: an analysis (1930-2014)

description: ABSTRACT This paper analyzes the trajectory of federal programs to promote reading and literature in Brazil. To this end, it investigates the period from the creation of the Ministry of Education and Public Health (1930) - the first governmental body to carry out reading promotion actions - until the establishment of the PNBE (1997-2014), the most comprehensive and expensive program for providing Brazilian public schools with literary collections. Our proposal is inscribed in the perspective that the book is not a neutral object (Chartier, 1990). Its curtailing, in a country marked by deep social inequalities, may point to interests of discourse appropriators (Foucault, 1996). The study of its history can therefore reveal these interests.
