Social Participation: the construction of democracy in Brazilian health
Cibelle Cristina da Silva Santos,Raquel Littério de Bastos
Revista Brasileira em Promo??o da Saúde , 2011,
Abstract: Objective: To verify the theoretical construction of the terms “social participation” and “social control” relating them to the process of construction of democracy in Brazilian health. Methods: A bibliographic survey conducted in Lilacs and Scielo databases in the period of 2002 to 2009, using the following descriptors: Unified Health System (SUS), Participation and Social Control, Health Policy. Results: The post-1988 Constitution period brought the democratization and decentralization of social policy making room for countless experiences of popular participation. The SUS was created to meet the demands of the population in face of that historic moment. But today, more than twenty years of its creation, the lack of understanding of its guiding principles by health professionals and the population consists in a challenge to its effectiveness. Conclusions: Despite the institutionalization of participation, a culture of non-participation and the lack of knowledge of its instruments are significant barriers to the practice of social participation in health, which represents a complex work that needs to be developed with active Citizen-State relationship.

Abstract: this study reports on 156 specimens of the amphibian eupemphix nattereri, a widely distributed leiuperid, obtained from 11 municipalities of central brazil. the extent of genetic variation was quantified by determining the mean number of alleles per locus and the proportion of polymorphic loci. an analysis of molecular variance (amova) was performed on the random amplified polymorphic dna (rapd) haplotypes. the genetic distances obtained by calculating pairwise fst among local samples were used to determine population relationships using the unweighted pair-group method (upgma) and non-metric multidimensional scaling (nmds). the cophenetic correlation was calculated to confirm agreement between the genetic matrix and the unweighted pair group method with averages (upgma) dendrogram. to determine if genetic distances were correlated to geographical distances we constructed pairwise genetic distance and geographical distance matrices and compared them using the mantel test. the amova results indicated significant genetic differences (p < 0.001) between e. nattereri populations, representing 69.5% of the within population genetic diversity. the mantel test showed no significant correlation (r = 0.03; p = 0.45) between the genetic and geographical distance matrices. our findings indicate that the genetic variation of e. nattereri populations was randomly distributed in geographic space and that gene flow for this species is probably structured at spatial scales smaller than those between our samples

The objective of this study was to evaluate the growth, the nutrition, and the intensity of the green color in corn plants in monoculture and in intercropping with Mucuna aterrima, Crotalaria juncea, and Canavalia ensiformis, cultivated with different handlings. In general, corn plants in monoculture demonstrated greater growth and greater SPAD value in the first evaluation, despite presenting lower tenor of phosphorus in the leaves when related to the corn in intercropping. The weed helps in the growth of the corn plant and increases the SPAD value during flowering. The monoculture NPK (Nitrogen, Phosphorus and Potassium) fertilization promoted higher values in corn plant growth, as well as a greater SPAD value, at 30 d.a.e., of the plants. The NPK-fertilized corn plants showed a greater tenor of sulphur and a lower tenor of molybdenum. The corn in intercropping with M. aterrima resulted in smaller plants at 70 d.a.e. It also presented a greater tenor of molybdenum and lower tenor of nickel when compared to intercroppings with C. juncea and with C. ensiformis. The corn plants in a intercropping with Crotalaria juncea presented higher growth at 30 and 70 d.a.e. and greater tenors of molybdenum when compared to the plants in intercropping with C. ensiformis.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.513195

The coffee seeds are problematic for the physiologycal quality, featuring low speed of seedling emergence. In this sense, this work was developed with the objective of evaluating the effect of sodium hypochlorite in the removal of the parchment and in the emergence and seedlings development of conilon coffee in nursery conditions. Coffee seeds of the variety Victoria were used, which were harvested in the cherry stage and pulped by hand. Seeds were dried in an oven with forced ventilation until reaching moisture contents of 35%, 30% and 25% wet basis. Then, the seeds with parchment were soaked in a sodium hypochlorite solution with concentrations of 4%, 5%, 6% and 7% active chlorine for 3 and 6 hours. For each moisture content, two additional treatments were added consisting of seeds with parchment and seeds in which the structure was removed manually. The characteristics evaluated were: emergence speed index, total emergence, dry mass of the shoots and root system. Utilization of sodium hypochlorite promoted an acceleration in seedling emergence speed similar to the method for manual removal of the parchment when using concentrations of 4%, 5%, 6% and 7% for 3 hours, at all moisture contents.

Obtaining adjusted prevalence ratios from logistic regression model in cross-sectional studies
Leonardo Soares Bastos,Raquel de Vasconcellos Carvalhaes de Oliveira,Luciane de Souza Velasque
Statistics , 2014, DOI: 10.1590/0102-311X00175413
Abstract: In the last decades, it has been discussed the use of epidemiological prevalence ratio (PR) rather than odds ratio as a measure of association to be estimated in cross-sectional studies. The main difficulties in use of statistical models for the calculation of PR are convergence problems, availability of adequate tools and strong assumptions. The goal of this study is to illustrate how to estimate PR and its confidence interval directly from logistic regression estimates. We present three examples and compare the adjusted estimates of PR with the estimates obtained by use of log-binomial, robust Poisson regression and adjusted prevalence odds ratio (POR). The marginal and conditional prevalence ratios estimated from logistic regression showed the following advantages: no numerical instability; simple to implement in a statistical software; and assumes the adequate probability distribution for the outcome.

Sba: Controle & Automa??o Sociedade Brasileira de Automatica , 2008, DOI: 10.1590/S0103-17592008000400003
Abstract: an approach to guide a mobile robot from an initial position to a goal position avoiding any obstacle in its path, when navigating in a semi-structured environment, is proposed in this paper. such an approach, hereinafter referred to as tangential escape, consists in changing the current robot orientation through a suitable combination of the values of the angular and linear velocities (the control actions) whenever an obstacle is detected close to it. then, the robot starts navigating in parallel to the tangent to the obstacle, regarding the point of the obstacle boundary the robot sensing system identifies as the closest one. the stability of the control system designed according this approach is proven, showing that the robot reaches any reachable goal, with or without a prescribed final orientation. such a control system is programmed onboard a mobile platform whose sensing system is a laser scanner which provides 181 range measurements, for experimental validation. the results obtained are presented and discussed, allowing concluding that the tangential escape approach is able to guide the robot along trajectories that result in a reduction of the traveling time, thus saving batteries and reducing the motor wearing.

Abstract: the objectives of the present study were to investigate the frequency and duration of nursing behaviour in female buffalos during the lactation period and the types of suckling behaviour in relation to age and calf sex. thirty-five females with their calves were observed during three consecutive days in each month, over a period of nine months. the nursing behaviour was characterized as isolated filial nursing (ifn); collective filial nursing (cfn) and nonfilial nursing (nfn). the suckling behaviour was classified as isolated filial suckling (ifs); collective filial suckling on their own mothers (cfs 1); collective filial suckling on other females (cfs2) and nonfilial suckling (nfs). data were analyzed by analysis of variance and means were compared by the tukey test considering p<0,05. ifn showed frequency and duration higher than the other types of the nursing (p<0,05), with predominance in almost all period of lactation.the frequency of ifs was high mainly in the first month and the duration of ifs was higher than other types of suckling until the fifth month (p<0,05) in relation to calf sex, no significant differences (p>0,05) were found for the means of frequency and duration of the types of sucking. the results show that the buffalo females have larger innate aptitude for ifn in relation to the other types of nursing during almost all the lactation period. the calves are more dependent on ifs during the first five months and the calf sex did not influence the types of suckling behaviour.
