Habitação e modernização: Cidade Nova e maneiras de viver em Natal no início do século XX

Analyses the presence of new standards of habitation detected in the construction of the region called Cidade Nova, in the first s years of the XX century. Associates the presence of these new patterns with the historical moment lived by the capital, marked by the urban modernization and by the changes of local life. Map voices that, introduced by the republican groups since 1889, pronounced the overcome of the old city of the XIX century asseverated a new model of town. Make use, as fundamental fonts of research, of the urban chronicles produced by the local intellectuals and the newspapers, like A República. Dialog with chronics that includes since propositions about the colonial past until the preoccupations about the acting of the State on how to order the public space. Identifies on those texts the political motivations and the elements whose where inherent to capitalism that accelerated the changes occurred in the urban space. Demonstrates the gradual occupation of Cidade Nova as an important modification happened in the city from that time on. That neighborhood adopted a new model on how to construct the houses of their citizens and helped to promote the urban life as a whole. From now on, Natal has a space meant for the home of their richest families. Recognizes, from many ways, many discourses, manners of living that was legitimized by the changing of the XIX to the XX century and has his highest point in the 1920´s. And it was representative of the strong attachment about the habits of refinery and order in the essence of the private life of the local urban elites

Acolhimento institucional e desenvolvimento moral: a generosidade em crianças de quatro a seis anos de idade em situação de abrigo

This research has as main proposal to verify how the virtue of generosity, considered as one of the important aspects of moral development on children, shows itself in children between four and six years old in institutional welcome condition. Toward this aim, knowledge in Human Development Psychology, specifically Jean Piaget and his contemporary collaborators, were associated to philosophic knowledge, with emphasis in Kant and Aristotle. The research took place in an institutional welcome service in the town of Natal-RN, between February and May of 2009, witch is responsible to offer care to children from zero till six years old. As procedure were used: the rulebased game Memory Game ; the childhood story One note fight ; and observations of the institution s everyday. The corpus analysis was done by the Thematic Content Analysis method. In general, in the daily observations, children showed themselves more co-operative and generous than in the executed procedures, mainly when the matter subject was other´s well-being. The duty, Kantian perspective, was overcome by the Aristotelian sumo bem, classified as generous act of afford to other what is not posted as right, however guaranteed by solidarity

Modos de aplicação de calcário e de micronutrientes em pomar de laranjeira 'Natal' e análise comparativa de custos

De acordo com o Agrianual (2005), a produção citrícola brasileira é de 17,7 milhões de toneladas ano-1,ocupando aproximadamente 1 milhão de hectares no território brasileiro e, deste total, 810 mil hectares localizam-se no Estado de São Paulo. A maioria dos solos brasileiros, inclusive aqueles onde foram instalados os pomares cítricos, apresenta reação ácida. Esta é, sem dúvida, a principal condição desfavorável dos solos e um dos fatores limitantes da produção em solos tropicais. O presente trabalho teve por objetivo estudar o efeito de diferentes modos de aplicação de calcário e de micronutrientes e analisar, de forma comparativa, os custos destes tratamentos em um pomar de laranjeira. O experimento foi desenvolvido na Fazenda Morumbi, município de Estrela D'Oeste-SP, num Argissolo Vermelho-Amarelo. A variedade de laranjeira utilizada foi a 'Natal', enxertada em limão Cravo, com 6 anos de idade e espaçamento 5 x 8 m. O delineamento experimental foi em parcelas subdivididas, com 3 repetições, com 5 tratamentos principais (sem calcário; a necessidade total de calcário (NC) incorporado; NC sem incorporação; ¹/2 NC no primeiro ano + ¹/2 NC no segundo ano e ¹/3 NC no primeiro ano, + ¹/3 NC no segundo ano, + ¹/3 NC no terceiro ano) e dois tratamentos secundários [micronutrientes via solo (FTE-BR 12: 11,5 % de ZnO e B2O3; 1% CuO; 5,4% de Fe2O3; 5,5% de MnO2; 0,2% de MoO3) e micronutrientes via foliar (sulfato de zinco a 0,5% e ácido bórico a 0,08%)], distribuídos em blocos casualizados. Não houve efeito significativo dos modos de aplicação da calagem e de micronutrientes sobre as variáveis avaliadas (produção, sólidos solúveis totais, acidez total titulável). Para massa média do fruto, o efeito significativo aconteceu apenas no primeiro ano, com a calagem em dose única e sem incorporação, e micronutrientes via solo. Concluiu-se que não houve efeito significativo dos modos de aplicação do calcário e dos micronutrientes para produção e massa média dos frutos da laranjeira 'Natal', e a receita líquida foi positiva em todos os tratamentos, sendo que o tratamento 5 [¹/3 da necessidade total de calcário (NC) no 1º ano + ¹/3 da NC no 2º ano, + ¹/3 da NC no 3º ano] apresentou o melhor valor acumulado (U$ 3.721,85 ha-1).

New technologies, old habits: automation without innovation

This research investigated the underuse of technological tools by innovative organizations which are acknowledged for their use of and familiarity with new technologies. The research conducted an analysis of 58 institutional repositories (IRs) out of 43 educational and research institutions which are internationally renowned for excellence. The core aspect of the analysis was the use of IRs for publishing and dealing with evidence in order to legitimize and add value to scientific research. The following items were analyzed: (a) the logical structuring of scientific communication published in the IRs; (b) the metadata which describe scientific communication based on the terms of the DCMI protocol used; (c) the availability of software functions which facilitate the queries and publication of evidences. Results show that the introduction of IRs did not add value to the quality of research in\ terms of associating and publishing evidence that could back them up. A strong tendency to replicate the traditional library model of physical collections was observed. It was concluded that merely possessing good technological tools is not sufficient for fostering innovation and strategic gains in organizations, even if their implementation takes place in highly promising and favorable environments.

Dois testes de imageamento com GPR em problemas de controle ambiental em regiões tropicais: migração de dunas e localização de dutos de óleo enterrados

Because the penetration depth of Ground Penetrating Radar (GPR) signals is very limited in high conductive soils, the usefullness of this method in tropical regions is not yet completly known. The main objective of this researh is to test the usefullness of the method in Brazil. Two typical problems where GPR has been used in Europe and North American were choosed for this test: the first one is to characterize the internal structures of a sand body and the second problem is the localization of old buried pipes lines. The first test was done near the city of São Bento do Norte, in the northern coast of Rio Grande do Norte state, NE Brazil. In this region, there is a sand dune that is migrating very fast in the direction of adjacent settling areas. To characterize the internal structure of the dune and its relationship to the prevailing wind direction, as a preliminary step to understand the dune migration, GPR profiles using the 400 MHz frequency were performed in E-W, N-S, NE-SW, and SE-NW directions over the sand dune intersecting at the top of the dune. The practical resolution of the GPR data is around 30 cm; this was sufficient to distinguish individual foresets inside the dune. After applying the elevation correction to the data, we identified that dips of bedding structures are smallest for the N-S profile, which is perpendicular to the dominant wind direction, largest for the E-W profile, and intermediate for the SW-NE and SE-NW profiles. Foresets in the E-W profile dip with angles varying from 2 to 6 degrees. In the E-W profile, the water table and a horizontal truncation interface separating two generations of dunes were identified, as well as an abrupt directional change in the foreset patterns associated to a lateral contact between two dune generations, the older one extending to the west. The used high frequency of 400 Mhz does not allow a penetration deep enough to map completely these internal contacts. The second test was done near Estreito, a small town near Carnaúbais city, also in Rio Grande do Norte state. In this locality, there are several old pipe lines buried in area covered by plantations where digging should be minimized. Several GPR profiles using the 400 and 200 MHz frequency were performed trying to intercept perpendicularly the possible pipe lines. Because of the high conductivity of the soil, the raw original data can hardly be use to identify the pipe lines. However, after an adequate processing over the 200 MHz profiles, six pipe lines were identified. As a global result of the tests, GPR can be very usefull if the conductivity of the ground is low or, in the case of medium conductivities of the soils, if adequate processing is performed

Trends and patterns of exclusive breastfeeding for under-6-month-old children

Objective: To study the trends and patterns of exclusive breastfeeding (EBF) for under-6-month-old infants in the city of Bauru, southeastern Brazil.Methods: We compared data from three cross-sectional surveys, using similar methodologies, which were part of a project for monitoring breastfeeding indicators in the state of São Paulo, Brazil. The sample included infants aged 0 to 6 months who attended one of the two rounds of the nationwide infant vaccination campaign in 1999, 2003 and 2006 (respectively: 496, 674 and 509 infants). Descriptive statistics were used to compare the prevalence of EBF according to age (in months) and group of children under 6 months of age. Differences in prevalence were expressed as percentage-points and submitted to statistical analysis (Pearson's chi-square and tendency), and the level of significance was set at p < 0.05. Factors associated with EBF interruption in 2006 were evaluated by univariate and multivariate analyses.Results: An increase in the prevalence of EBF was observed in under-6-month-old infants: 1999-2003, increase of 9.1 percentage-points; 2003-2006, increase of 6.6 percentage-points, resulting in an annual increase rate of 2.3 percentage-points for the first period and 2.2 percentage-points for the second period. Significant inverse association was observed between EBF and the use of pacifiers (prevalence ratio = 2.03; 95% confidence interval 1.44-2.84).Conclusion: EBF prevalence in under-6-month-old infants in the city of Bauru, southeastern Brazil, increased almost threefold over the period studied, from 8.5% in 1999 to 24.2% in 2006, a total increase of 184.7%. The use of pacifiers was the only factor strongly associated with the interruption of EBF.

Salivary cortisol to assess the hypothalamic-pituItary-adrenal axis in healthy children under 3 years old

Objective: To establish reference concentration intervals for salivary cortisol in healthy children, in the morning and in the afternoon, investigating factors that interfere with the concentration measured and the possibility that circadian rhythms are present.Methods: A controlled observational study was carried out with 91 children aged 45 days to 36 months, selected at random and living in Santo Andre, state of São Paulo, Brazil. Inclusion criteria were: healthy, well-nourished, free from fever and corticoid use, subdivided by age group (five subsets) at 6-month intervals. Saliva was collected during home visits in the morning and afternoon. Cortisol was radioimmunoassayed with cortisol 3-oxime-bovine albumin antiserum.Results: the five subsets exhibited higher cortisol concentration during the morning than in the afternoon (p < 0.001), and this difference passed 30% from 1 year of age onwards. Mean concentrations, in nmol/L, were 557.86 (morning) and 346.36 (afternoon). A negative linear correlation was observed between morning concentrations and hours' sleep and frequency of meals (p < 0,05), and in the afternoon with anthropometric measurements (p < 0.05).Conclusions: Reference values for normal salivary cortisol in healthy children were established. At:45 days it was possible to observe circadian rhythms, which reached maturity at 12 months of life. Sleep and food deprivation increased morning cortisol levels.

Blood galactose and glucose levels in mothers, cord blood, and 48-hour-old breast-fed full-term infants

Background: Although galactose is an important component in human lactose, there are few reports of its role in the newborn metabolism. Objective: To determine the relationship of blood galactose and glucose levels in mothers, cord blood, and breast-fed full-term newborn infants. Methods: Maternal and cord vein blood samples were obtained from 27 pregnant women at delivery, and from their breastfed, full-term newborns 48 h later. Galactose and glucose were determined by HPLC. Statistical analysis used ANOVA and Pearson correlation with p < 0.05. Results: Maternal galactose concentrations (0.08 +/- 0.03 mmol/l) were similar to cord blood galactose (0.07 +/- 0.03 mmol/l; p = 0.129). However, newborn blood galactose (0.05 +/- 0.02 mmol/l) was significantly lower than both cord (p = 0.042) and maternal blood (p = 0.002). Maternal blood glucose levels (4.72 +/- 0.86 mmol/l) were higher than cord blood (3.98 +/- 0.57 mmol/l; p < 0.001), and cord blood concentrations were higher than newborn blood levels (3.00 +/- 0.56 mmol/l; p < 0.001); all values expressed as mean +/- SD. Significant correlation was only seen between maternal and cord blood galactose levels (r = 0.67; p < 0.001) and glucose levels (r = 0.38; p = 0.047). Conclusion: the association and similarity between maternal and cord blood galactose levels suggest that the fetus is dependent on maternal galactose. In contrast, the lower galactose levels in newborn infants and a lack of association between both suggest self-regulation and a dependence on galactose ingestion. Copyright (c) 2007 S.
