title: Perception of risk sources by chilean blueberry producers

description: Abstract The biological and environmental nature of the agricultural production implies that growers operate in an environment of greater risk as compared to other economic activities. This has implications on the manner in which the growers can manage the risks inherent to their activity, which depends on how they perceive the risks and on the degree of aversion to risk. The main objective of this study was to learn about the perception of the main sources of risk that blueberry growers face in the Maule Region, Chile. This Region has about 25% of the planted area of this species in Chile. We used information from questionnaires implemented in 124 fields which considered two independent groups of growers: 48 owners and 76 managers. A scale of Importance of the Sources of Risk (ISR) was used. It included 13 items that the interviewed had to rank according to their importance through a Likert-type scale of four levels. The exploratory analysis allowed to infer that the ISR scale had adequate levels of internal consistency (Cronbach´s alpha = 0.83). The results showed that the climatic events are perceived by the growers as the main source of risk for blueberry production in Chile. The analysis also showed that the price of the product and the currency exchange rate are the next risks in importance for the field owners. On the other hand, the risks for the managers were, in decreasing order of importance: yield, product price, variability in sales, and volumes for sale. The knowledge of the perception of risk by the growers is a fundamental input for designing instruments of agricultural policies, risk management and support programs for the growers.

title: Relationship between zooplankton richness and area in Brazilian lakes: comparing natural and artificial lakes and trends

description: Abstract Aim We analyzed the relationship between zooplankton species richness and the area of 34 natural and 55 artificial lakes in Brazil (total of 89), with area varying between 0.01 to 2,430 km2. Methods A total of 33 studies were found in the specialized bibliography, containing data from zooplankton sampled in the limnetic areas, here analyzed through descriptive statistics, nonparametric group comparisons, Spearman correlation, and non-linear regression. Results The relationship between zooplankton richness and area in Brazilian lakes depend both on the size and type of the environments. Contradicting aspects of the biogeographic theory, in small environments (up to 6 km2) there is no significant influence of the area on the richness, whether it is natural (ponds) or artificial (dams, reservoirs). The natural lakes present greater richness and habitat variation independent of the size, possibly due to a more diverse composition of niches. Large natural lakes are scarce in Brazil but, with dams, area and zooplankton richness are positively correlated on an intermediate scale, up to 39 km2, critical point of size from which species’ richness stabilizes. Conclusions For the artificial lakes of large or intermediate size in Brazil, area and richness of microcrustaceans have a point from which richness starts to stabilize, as would be expected by the biogeographic theory. But in small size environments there is no evidence confirming this association. Also, it is observed that the natural lakes present higher and more variable values for richness than the artificial ones.

title: Preterm Birth, Pacifier use and Breastfeeding: is there a Relationship?

description: Abstract The immaturity of born to preterm infants may predispose to sucking difficulties. This research aimed to evaluate if pacifier use is associated with preterm birth and influenced in type of infant feeding. This comparative cross-sectional study was conducted in Belo Horizonte, Brazil and evaluated 250 children aged 3 to 5 years. As a sample, two groups were established: the normal term children group (n=125) was selected at a day-care centre and the group of preterm children (125) was identified at a public university hospital with a preterm care project from birth to seven years of age. To collect data, a pre-tested questionnaire regarding information on gestational age, infant development, infant feeding and non-nutritive sucking habits was used for both groups. Bivariate and multivariate Poisson regression was used for the statistical analysis. Pacifier use was more prevalent in the preterm group (PR=1.20, 95% CI=1.02-1.42) who used the bottle (PR=1.38, 95% CI=1.15-1.64) and were breastfed for less than six months (PR=1.19, 95% CI=1.01-1.41). The majority of breastfed infants were of normal term birth (PR=1.14, 95% CI=1.04-1.20) and had monthly family income greater than USD 450.28 (RP= 1.10, 95% CI=1.01-1.20). In this study, pacifier use was more prevalent among preterm infants and associated with less than six months of breastfeeding and used of bottle. Monthly family income was associated with a prevalence of breastfeeding.

title: Balance of Dissertations and Theses in Special Education and Inclusive Education Developed in The Graduate Programs in Education in Brazil

description: ABSTRACT: This paper aims to discuss succinctly the "places" of master's theses and doctoral dissertations in Special Education in Brazil. It is sought to unveil its emergence and consolidation as an object of research within the Graduate Programs in Education (GPEs). Methodologically, the realization of this balance required the statistical update and the collection of general information (bibliographical data and summaries) about the theses and dissertations under analysis. This information has been organized and systematized into two databases, namely: 1) Pro-Identi; and 2) Caracter. The main results indicate that in the period from 1971 to 2016, 2,864 master's theses and 711 doctoral dissertations were defended, making a total of 3,575 defenses in Special Education, within the framework of the Brazilian GPEs. These researches were developed in 134 programs, with emphasis on the Graduate Program in Special Education of the Federal University of São Carlos, and ten other GPEs that together concentrate 49.3% of the production in the field. When consubstantiating the authors consulted and the survey made, it was possible to identify and characterize three periods of this research in the country, namely: Pioneerism, Expansion and Consolidation. Finally, synthetically, it is reasonable to consider that 45 years after the defense of the first master's thesis in Special Education in Brazil, research on this subject is consolidated in the country.

title: Family Religiosity and Oral Health Related Quality of Life: a Multilevel Analysis in Brazilian Schoolchildren.

description: Abstract Religiosity has been associated with a better dental condition and positive self-perception of health, but there are no studies on the relationship between religious practice and oral health-related quality of life (OHRQoL), especially among schoolchildren. Thus, the aim of this study was to evaluate the association between family religiosity and OHRQoL in 12-year-old schoolchildren. We conducted a cross-sectional study in a representative sample of 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. A total of 1,134 schoolchildren were assessed in a randomly selected in 20 public schools in the city. Participants were examined by 4 calibrated dentists (minimum Kappa-value for intra and inter-examiner agreement were 0.79 and 0.77, respectively) according to dental caries (Decayed, Missed, Filled Teeth Index), and gingival bleeding (Community Periodontal Index criteria). OHRQoL was assessed by the Brazilian short version of Child Perceptions for Questionnaire (CPQ11-14). Parents or guardians answered a structured questionnaire regarding their socioeconomic status and religious practice. Data were analyzed using multilevel Poisson regression analysis to assess the association of religiosity and overall and domain-specific CPQ 11-14 scores. Religious practice less than once a week was associated with higher mean symptoms domain scores and higher mean CPQ 11-14 overall scores in schoolchildren. In conclusion, our findings demonstrate that family religiosity was positively associated with schoolchildren’s OHRQoL.

title: Standard area diagram set for bacterial spot assessment in fruits of yellow passion fruit

description: Abstract This study developed and validated a standard area diagram set (SADs) for severity assessment of bacterial spot (Xanthomonas axonopodis pv. ) in passifloraefruits of yellow passion fruit (Passiflora edulis). The SADs consisted of eight severity levels (1%; 3%; 5%; 10%; 21%; 38%; 65%; and 80%). For its validation, 20 raters, who initially estimated the disease severity without the aid of the SADs, were divided into groups (G1 and G3, inexperienced; G2 and G4, experienced). Subsequently, G1 and G2 performed the second evaluation without the proposed SADs, and G3 and G4 completed the second evaluation using the proposed SADs. The accuracy and precision of the assessments were determined by simple linear regression and by the Lin’s concordance correlation coefficient. The increase in the accuracy was confirmed by the reduction in the constant and systematic errors, indicating that the estimated severities were close to the actual values when the SADs was used. Inexperienced raters benefited the most from the use of the SADs, and 60% and 100% of them presented constant and systematic error-free estimates, respectively. Precision increased with the increase in the coefficient of determination, the reduction in absolute errors, and the increase in the reproducibility of the estimates between pairs of raters.

title: Diel vertical migration of Cladocera in a compartment of a tropical reservoir

description: Abstract Aim This study seeks to analyze the vertical migration pattern of Cladocera species as related with the physical and chemical parameters of the water. Methods Samplings were carried out at 3-h intervals for 24 h in January 15 on the Sapucaí River compartment of Furnas reservoir, Minas Gerais State, Brazil. These samples were taken at five depths, from the surface to the near-bottom layer (0, 2, 4, 6, 8, and 9 m) totalizing 54 samplings for each limnological variable (temperature, pH, dissolved oxygen, electrical conductivity, chlorophyll-a content, Index of Trophic State, water transparency and Cladocera populations abundance). The samplings were performed at the limnetic region at a point with total depth of 9 meters. Results Water column thermal and chemical stratifications and thermocline occurrences were registered in the middle of the day. Among the 14 Cladocera species, only Ceriodaphnia cornuta and C. silvestrii displayed a significant migration pattern, which was mainly related to chlorophyll-a and dissolved oxygen concentrations. Diaphanosoma birgei and D. spinulosum are found at high densities near the surface and low ones in depth. The migration of Diaphanosoma was directly related to the concentration of chlorophyll a and pH, thus acting as a limiting factor. Feeding at high temperatures in the surface layer and assimilating at lower ones in depth, usually confer metabolic advantages to the vertically migratory species. Conclusions In this study, a well-defined pattern of vertical migration was found for two Cladocera species and its possible causes were hypothesized. To the species with less locomotory capacity, thermal and chemical stratifications can act as barriers to migration and distribution through the water column. This pattern may probably be found for zooplankton species in other compartments of Furnas reservoir, with similar physical and chemical properties.
