title: Spatial partitioning between juveniles and adults of the freshwater anomuran crab Aegla parana (Crustacea Aeglidae) from southern Brazil

description: ABSTRACT In order to understand the role of lower order tributaries in the population structuring of the freshwater anomuran crab Aegla parana Schmitt, 1942, a study on the distribution of demographic categories was carried out along Negro River and in its tributary Totó River that belong to Upper Iguaçu Basin, southern Brazil. Two collection points were established along the main channel of Negro River, in a 7.00 km long stretch, and three points in the entire creek Totó River with 6.61 km long. The animals were captured with Surber net and baited traps and had the carapace length (CL) measured. A total 146 crabs were obtained from Negro River and 361 from Totó River, performing 507 analyzed aeglids. From the point 1 of Negro River, males measured 27.68 ± 12.68 mm CL and females 18.98 ± 5.88 mm CL; from point 2 of the same river, the values were 24.45 ± 13.70 mm CL and 27 ± 8.50 mm CL, respectively. There was a positive and direct relationship between the mean CL of the aeglids from Totó River and the distance of the collection points from its source. Males: point 1 (source of the creek): 7.90 ± 1.23 mm CL; point 2: 9.55 ± 3.06 mm CL; point 3: 9.91 ± 2.62 mm CL. Females: point 1 (source): 6.68 ± 1.70 mm CL; point 2: 9.01 ± 1.94 mm CL; point 3: 10.49 ± 2.57 mm CL. The sexually immature aeglids are distributed mainly in the lower order tributary (= Totó River), and the mature ones in the main channel of Negro River, indicating that this population perform ontogenetic migrations from tributary to the main river. The spatial partition can be explained under three aspects that are quite contrasting between Negro River and Totó River: 1. substrate architecture; 2. depth of the water column and 3. quality of available food.

title: Incontinence outcomes in women undergoing retropubic mid-urethral sling: a retrospective cohort study comparing Safyre™ and handmade sling

description: ABSTRACT Purpose This study examined and compared efficacy, safety, satisfaction, and complications of the retropubic Safyre™ sling and a retropubic hand-made synthetic sling (HMS) in a short-, mid- and long-term follow-up. Methods We retrospectively reviewed a prospectively maintained database of women who underwent Safyre™ or HMS between March 7ths 2005 and December 27ths, 2017. Patients had first assessment (7-10 days), second (40-45 days), and third (sixth month) postoperatively. Between September and December 2018, patients who completed at least one year of surgery, received a telephone call. Follow-up compared quartiles of follow-up time to determine complications (Clavien-Dindo), success rates (International Consultation on Incontinence Modular Questionnaire for Urinary Incontinence Short Form – ICIQ-UI SF), and patient satisfaction. Results Three hundred fifty-one patients underwent surgery and 221 (63%) were evaluated after a median of 78.47 (± 38.69) months, 125 (55%) in the HMS, and 96 (45%) in the Safyre™ group. Higher intraoperative bladder injury was observed with Safyre™ (0% vs. 4.2%, p=0.034), and a tendency for urinary retention, requiring indwelling urinary catheter over 24 hours (2.4% vs. 8.3%, p=0.061). Both HMS (p&lt;0.001) and Safyre™ (p&lt;0.001) presented improvements on ICIQ-UI SF. There were no differences in satisfaction, subjective cure rates, ICIQ-UI SF, or complications between groups. Conclusions Both HMS and Safyre™ have similar satisfaction and subjective cure rates, with marked ICIQ-UI SF score improvement. Higher rates of intraoperative bladder injury were seen in patients who received Safyre™ retropubic sling.

title: Perceptions of the local government and the residents regarding rural tourism development effects. Survey in the Suceava County - Romania

description: ABSTRACT: Rural tourism has received more and more attention because it can contribute to increase the living standard in some rural areas, stimulate local economy and reduce the urban-rural gaps. At the same time, the preference for this type of tourism is growing, but for the efficient use of the existing potential, the involvement of local authorities and residents is needed. This paper revealed the perceptions of human resources in local government institutions and of residents in Suceava County - Romania to identify the effects of tourism development on the administrative process, living standards and natural environment. The undertaken questionnaire-based research showed that the degree of tourism development positively influenced the level of improvement of the public affairs management process in the respective administrative-territorial unit, as well as the standard of living of the local community. Regarding the influence of tourism development on the environment, the recorded results showed that the intensification of the tourism phenomenon does not strongly threaten the local environment, but it is necessary to raise awareness of the environmental impact.

title: THE CHARACTERISTICS OF QUALITATIVE RESEARCH: A STUDY WITH THESES FROM A POSTGRADUATE PROGRAM IN EDUCATION

description: ABSTRACT: The mode of production of scientific knowledge has become complex, leading to the use of research methodological elements that also investigate subjective issues. This study aims to analyze characteristics of PhD theses that adopted the qualitative approach, defended at a Postgraduate Program in Education (PPGE) of a University of the Northeast Region of Brazil, 2013-2016 quadrennium. The theoretical basis of the work is based on contributions from Evandro Ghedin, Marcos Zanette, Marli André and Maria Amélia Franco. To achieve the proposed objective, a quali-quantitative documentary research was developed, based on the identification and analysis of the categories: theme, method, data collection procedure and data analysis technique, synthesized by grouping data extracted from theses abstracts. It was found that, of the amount of 57 theses defended in the period considered, 87.7% (n=50) used a qualitative approach, although only 32.0% (n=16) of these explain this approach in their summary. Public policy and teacher education are the most present among themes. 42.0% (n=21) of the theses clearly indicate the research method, with emphasis on documentary research. There are multiple data collection procedures in them, especially interview and document collection. In 46.0% (n=23) of the theses, the data analysis technique is specified, mainly content analysis. However, it is considered important that researchers in the field of Education clearly inform all the methodological elements of their theses in their abstracts.

title: Partially Dehulled Sunflower Seeds in Diets for Grazing Chickens: Effect in Meat Quality

description: ABSTRACT The effect of including partially dehulled sunflower seeds in the diet of grazing chickens in meat quality was evaluated. Two hundred and forty, one-day-old, Ross 308 chickens were used, randomly distributed into four treatments with six replicates of 10 birds each. Seventy-two birds were slaughtered at seven weeks of age, 18 per treatment, extracting the Pectoralis major muscle to analyze meat quality. The treatments were completely randomized in a 2x2 factorial arrangement, where type of rearing (confinement or grazing) and diet (base diet or base diet substituting 10% soybean meal for partially dehulled sunflower seeds) were the independent variables. The grazing chickens spent 8 hours a day in a white clover (Trifolium repens) paddock. Including sunflower seeds improved (p&lt;0.05) the color and crude protein (CP) in breast meat (p&lt;0.05), while grazing increased (p&lt;0.05) CP, dry mater (DM), and shear force (SF), and the percentage of breast fat decreased (p&lt;0.05) by up to 50%. Additionally, grazing increased (p&lt;0.05) saturated fatty acids (SFA) and reduced (p&lt;0.05) lipid oxidation by up to 50%. Partially replacing soybean meal with partially dehulled sunflower seeds in the diet of grazing chickens with white clover improves the physicochemical characteristics and nutritional quality of the breast meat; it also decreases lipid oxidation, extending the shelf life of the meat.

title: Evaluating the relationship between water quality and water treatment costs with land use change at multiple spatial scales: a case study of watersheds in southern Bahia, Brazil

description: ABSTRACT The current global loss of biodiversity has threatened the provision of drinking water for public supply, mainly due to the loss of native forests. Thus, understanding the impacts of vegetation cover reductions in altered landscapes by human activities is an important action to ensure water security. This study evaluated the relationship between water quality and treatment costs with land use intensifications of six water catchment points for public supply in southern Bahia, Brazil. Six spatial scales were considered, the catchment point and its surroundings (local), four riparian zone buffers (30, 50, 100, and 200 m), and the watershed. A selection of models was conducted to determine the scale at which landscape intensification best explains treatment costs and water quality. By using a principal component analysis in each spatial scale, a gradient of forest replacement by other non-forest uses (PC1) was generated and used as an explanatory variable. As a result, land use intensification at the 100 m riparian zone was the best model for both response variables. Therefore, our study suggests that actions for conservation and restoration of water resources in our study area should consider a riparian zone of at least 100 m on each side of the water bodies to reduce treatment costs in a medium-to-short term. Also, recovering forest cover is a crucial action to manage riparian zones and watersheds.

title: Laboratory-based study of drug resistance and genotypic profile of multidrug-resistant tuberculosis isolates in Salvador, Bahia, Brazil

description: Abstract Background: Surveillance of multidrug resistant/extensively drug-resistant tuberculosis (MDR/XDR-TB) is essential to guide disease dissemination control measures. Brazil contributes to a significant fraction of tuberculosis (TB) cases worldwide, but only few reports addressed MDR/XDR-TB in the country. Methods: This cross-sectional, laboratory-based study describes the phenotypic resistance profiles of isolates obtained between January 2008 and December 2011 in Bahia, Brazil, and sociodemographic, epidemiological, and clinical characteristics (obtained from mandatory national registries) of the corresponding 204 MDR/XDR-TB patients. We analyzed the mycobacterial spoligotyping and variable number of tandem repeats of mycobacterial interspersed repetitive units in 12-loci profiles obtained from Salvador. Results: MDR/XDR-TB patients were predominantly male, had a median age of 43 years, belonged to black ethnicity, and failed treatment before MDR-TB diagnosis. Nearly one-third of the isolates had phenotypic resistance (evaluated by mycobacteria growth indicator tube assay) to second-line anti-TB drugs (64/204, 31%), of which 22% cases (14/64) were diagnosed as XDR-TB. Death was a frequent outcome among these individuals and was associated with resistance to second-line anti-TB drugs. Most isolates successfully genotyped belonged to the Latin-American Mediterranean (LAM) Family, with an unprecedented high proportion of LAM10-Cameroon subfamily bacilli. More than half of these isolates were assigned to a unique cluster by the genotyping methods performed. Large clusters of identical genotypes were also observed among LAM SIT42 and SIT376 strains. Conclusions: We highlight the need for strengthening local and national efforts to perform early detection of TB drug resistance and to prevent treatment discontinuation to limit the emergence of drug-resistant strains.

title: Diffusion of Innovation in Technological Platforms: The Uber Case

description: ABSTRACT Objective: diffusion theory suggests that customers adopt innovation. However, no research has examined the differences between peers and the balance required of a peer-to-peer platform in the diffusion process. This article investigates whether there was a peer-to-peer balance in the diffusion process of a technological platform, represented here by the Uber case. Methods: a total of 843 Uber users, comprising 397 drivers and 446 customers, took part in a probabilistic sample survey in Belo Horizonte, Brazil. The study tests the hypothesis of P2P platform diffusion balance along Rogers’ curve with Levene’s and t-test. Results: the findings are counterintuitive and unexpected. Although the authors expected passengers and drivers to show a similar predisposition for Uber’s adoption, empirical data did not confirm this. In contrast to the literature, which predicts that adoption occurs mainly in the initial phases, drivers’ predisposition showed a constant diffusion curve. Conclusions: considering the peer-to-peer platform context, this article shows that the balance between peers can still be present considering the multiple actors involved, which shows a proposition for this research. Besides, this article develops the ‘technological readiness indicator,’ thus enabling a better understanding of different empirical contexts.
