title: Ludic-activities-based therapeutic suitcase for rehabilitation of people with stroke

description: Abstract Introduction: Osteoarthritis (OA), the most common form of arthritis, is considered the main cause of pain and disability in elderly people. Objective: To evaluate the effect of systematic muscle strength training on functional performance and quality of life in individuals with knee OA. Method: Subjects with knee OA (n = 27, 46-76 year-old) completed the Western Ontario and McMaster Universities Osteoarthritis Index (Womac), Medical Outcomes Short-Form 36-item Health Survey (SF-36), and Visual Analog Scale (VAS) questionnaires, musculoskeletal assessments, and 10-repetition maximum and timed 10-meter walk tests both before and after training. The training consisted in an exercise resistance program and stretches for twelve weeks (three sessions of 80 minutes per week). Results: Twenty-two individuals completed the training. Reduced overall scores and Womac physical function indicated improved functional performance (p &lt; 0.001) as well as increased gait speed (p &lt; 0.001). The perception of pain decreased after training, as evidenced by the VAS, Womac pain domain, and SF-36 scores (p &lt; 0.001). Quality of life improvements occurred primarily in the areas of pain, functional capacity, and SF-36 physical aspects. No change in body mass index was noted (p = 0.93). Conclusion: Our results indicate that the combination of resistance training for the quadriceps, gluteus, and abdominal muscles could be a viable alternative to improving functionality and quality of life in patients with knee OA. However, more studies are necessary to confirm our findings.

title: Index of severity of musculoskeletal symptoms in keyboardists

description: Abstract Introduction: Musicians may present musculoskeletal pain, weakness, numbness, and tingling due to repetitive exercises. Objective: To evaluate the severity index of musculoskeletal symptoms (MS) in keyboard players. Method: A cross-sectional study including volunteers of both sexes, aged between 18 and 40 years, who performed professionally for at least 2 years, played the keyboard for at least 3 hours a week, and did not present previous history of trauma or rheumatic, neurological, and systemic diseases. The MS and its severity index were evaluated using the Nordic Musculoskeletal Questionnaire and the intensity was assessed on a scale of 4. The difference between the prevalence of musculoskeletal pain according to the anatomical region was analyzed using Fisher’s exact test. For all analyses, a significance level of 5% was adopted. This research was conducted after the ethics committee approval (No. 2,627,609). Results: Thirty-nine volunteers with discomfort were evaluated. Pain in the thoracic and lumbar spine in the last 12 months was most common (n = 27, 69.24%; p &lt; 0.031), and in the last seven days, lumbar spine pain occurred in 12 (30.76%; p &lt; 0.001). A severity index of 2 was the most frequent (n = 21, 54%). Conclusion: Keyboardists present with MS mainly in the vertebral column, and the severity of the symptoms is significant, suggesting the importance of prevention and treatment of MS before their onset.

title: Network theory of stakeholder influences: a revisited approach

description: Abstract The interactions among multiple stakeholders have gained importance in the last decades, given the speed with which information is spread and connections are established between individuals and groups. However, there is still a research gap, which is the lack of consolidation of the empirical studies that analyzed the phenomenon of stakeholder networks and their contribution to the advancement of the theory. Thus, this work aims to investigate the evolution of the stakeholder networks approach in the last 20 years, that is, to revisit Rowley’s theory (1997) and to bring a panorama of its evolution to the present day. This essay is based on two research scopes: Network Theories - society in networks and interoganizational networks and Theory of Stakeholders, integrated in the composition of Rowley’s proposal (1997) - Network Theory of Stakeholders Influences. From a sociometric analysis and systematic review of 228 articles collected in the Web of Science between 1997 and 2017, it was possible to analyze the evolution of this approach. Based on this reflection, it is possible to infer that recent research shifts the focus of the relations with the stakeholders, centered in the organization, to those of a decentralized network with several actors. In addition, there is a trend of studies of networks formed by groups of stakeholders and the social identities of individuals members of these groups. The contribution of this study consists of presenting an overview of the Theory of Stakeholder Networks analyzing reference networks, theoretical and empirical contributions, trends and research agenda for the theme, which will help in the development of future work.

title: Rapid quantitative analysis of six flavonoids in licorice by ultra-performance convergence chromatography

description: Abstract Objective This study was to establish a rapid quantitative method for determination of six characteristic flavonoids, including licochalcone A (1), liquiritigenin (2), glabridin (3), isoliquiritigenin (4), liquiritoside (5), and isoliquiritoside (6) in licorice by a ultra-performance convergence chromatography (UPC2) apparatus equipped with a photodiode-array detector (PDA). Methods: The flavonoids studied were separated on an ACQUITY UPC2 TM Torus 2-PIC column (2.1 × 100 mm, 1.7 μm) using gradient elution (85:15–70:30) with a mobile phase consisting of CO2 and methanol: formic acid (99.8:0.2, v/v), back pressure of 2,000 psi, flow rate of 0.8 mL/min, and detection at 254 nm. This method was further applied for the analysis of the flavonoids present in 10 batches of licorice roots samples. Results: Good linearity (R2 = 0.9990–0.9998) was achieved and limits of detection (LOD) and quantification (LOQ) ranging from 0.12 to 0.49 µg/mL and 0.46 to 1.61 µg/mL, respectively. The relative standard deviations (RSD) for repeatability and reproducibility were 2.30–2.80% and 2.30–2.98%, respectively. The flavonoids distributed differently in Glycyrrhiza uralensis , Glycyrrhiza glabra, and Glycyrrhiza inflate . Conclusion: The established rapid quantitative analysis method was environment friendly and suitable to the quality control of species licorice.

title: Full-Length Genomic Characterization of Chicken Anemia Virus in Turkey

description: ABSTRACT Chicken infectious anemia (CIA) is an immune-suppressive disease caused by chicken anemia virus (CAV). It is characterized by lymphoid atrophy, aplastic anemia, especially in chicks. In this study, full-length genomic characterization of CAV DNA from the broiler flocks in Turkey and phylogenetic analysis were aimed. In the study, CAV DNA were found positive for 37 (53%) flocks with PCR studies from thymus tissues of each 70 broiler flocks. And 17 purified CAV DNA PCR products from these 37 CAV isolates were full length sequenced with the NGS method (Illumina MiSeq). Also with the phylogenetic analyses, full length PCR products of 17 purified CAV isolates have been determined as 2298bp genome size and 99% similarity with each other. The highest similarity (99%) has been detected with the isolates from China and Taiwan. Furthermore, a 97-98% similarity has been detected with vaccine strains (Cux-1, 26P4 and Del Ros) and also 88-90 % similarity has been detected with GyV4 and GyV3 isolates. As a result, in the study full length genomic characterization of CAV DNA from the 7 regions of Turkey were determined. And also all Turkish CAV isolates and vaccine strains were in group 2 according to the phylogenetic tree were obtained. But these isolates and vaccine strains were not found in the same group with GyV3 and GyV4 strains. Besides, these CAV isolates were showed more similarity to the isolates reported from Taiwan and China than the vaccine strains.

title: Performance measurement and management in building companies

description: Abstract The literature on performance measurement and management shows the embryonic stage of these processes in the construction industry. Thus, this paper aimed to evaluate the Performance Measurement and Management (PMM) process in the construction sector. A multiple case study in three construction companies showed that the performance measurement systems (PMS) in use in these companies are focused on operational aspects of performance measurement, and are unable to promote their integrated management for more strategic purposes, such as influencing the behaviour of the actors and providing learning and improvement, fundamental elements to the successful of any organisation. Thus, this study contributes to construction management literature by expanding and deepening the discussion on the differences between measuring and managing performance, offering new ways to interpret the PMM, based on different concepts emerging from administrative and economic disciplines. This project also contributes by offering empirical evidence that reinforces the slow evolution of this subject in the construction sector.

title: Portfolio turnover and performance of equity investment funds in Brazil

description: ABSTRACT The purpose of this paper was to analyze the relationships between the portfolio turnover and performance of equity investment funds in Brazil. There are few published studies on the subject, but the previously identified Brazilian studies that have examined making changes to portfolios have been limited to very restricted data samples and have only worked with an ordinary least squares (OLS) model without taking into account the indications of international studies and economic theory itself of the possible endogeneity of turnover, which would make OLS estimation inadequate. The expressive growth of the fund industry in the Brazilian market shows the relevance of the object of research. Two portfolio turnover metrics were analyzed: one based on changes in the monetary values of the assets and another based on changing the weights of the assets in the portfolio. The estimations were performed for fixed effects panel data and then for a two-stage least squares model, using instrumental variables. The funds that make up the sample are those classified as “free shares” in the period from January of 2012 to January of 2018. The results showed that there is a positive relationship between the portfolio turnover and performance of the equity investment funds, showing that managers have been able to take advantage of moments of mispricing in the market and that they carry out more trades in search of higher returns. This research extends the results in the literature as it shows that there is a positive relationship between the turnover and performance of equity investment funds that is independent of the way turnover or performance are measured, which has shown inconclusive results in previous studies. Furthermore, it presents evidence for a more representative and current sample in an emerging market.

title: Young people’s career choices based on employer branding

description: Abstract This article critically discusses the relevance of brands in young undergraduate students’ choices when looking for internships and jobs. The research is based on the debate around the modern concepts of employer branding, consumption and lifestyle, and prosumption and co-creation. Interviews were conducted with 18 students at the end of an undergraduate program in business administration at a public university in the south of Brazil. The main results show that younger students become prosumers of their employer’s brands and their careers are based on seeking to work for the best brands, which is associated to intermittent jobs and vulnerable work relationships. However, the employers do not seem to offer enough elements to retain young workers.

title: Occupational heat exposure in outdoor activities in building structures

description: Abstract In the construction industry, excessive heat exposure may cause thermal overload and damage workers' health. This study presents an analysis of the heat exposure of sixty-four workers performing activities on concrete slabs in the construction of concrete structures in buildings. In order to do that, the Wet Bulb Globe Temperature (WBGT) obtained from temperatures of natural wet bulb, dry bulb and black globe, measured on the slabs and analysed along with estimated metabolic rates was used for each work function, according to standards from International Standardization for Organization (ISO). The evaluation was made using criteria set by Brazilian laws, applying the Regulatory Standard Number 15 from the Ministry of Labour. The results showed there is a need to manage and adopt control measures, especially thermal rest breaks, aimed at body cooling to avoid diseases caused by heat. The study concluded that as the number of hours of thermal recovery rest is significant in relation to the number of total hours of work measured (39% for heavy activities and 20% for moderate activities), the adequate work/rest scheme can potentially affect the work pace in construction.

title: Mineral and centesimal contents, antioxidant activity and antimicrobial action of phenolic compounds from Eugenia Brasiliensis Lam. Pulp

description: Abstract Phenolic compounds (PC) have presented antioxidant potential as well as antimicrobial action against several bacteria. This study aimed to extract PC from grumixama (Eugenia brasiliensis Lam.) pulp using solid phase extraction (SPE), then quantify the PC by Folin-Ciocalteu assay, and to evaluate the antioxidant activity (AA) from PC by DPPH, ABTS and FRAP methods as well as its antimicrobial activity by plate diffusion assay (PDA) and Minimal Inhibitory Concentration (MIC) assays. Additionally, the centesimal composition of the fruit and its mineral content by Total Reflection X-Ray Fluorescence Spectroscopy were determined. The fruit is a good source of PC which presented a higher contribution on AA from pulp than NPHRC. Calcium was the trace element in highest concentration in the pulp, followed by iron. PC from grumixama inhibited the growth of Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa but not Escherichia coli and Listeria monocytogenes in the PDA. PC showed antimicrobial activity against the five microorganisms tested in the MIC assay, in which S. aureus and B. cereus were the most sensitive. This study highlights the antioxidant and antimicrobial potential of Eugenia brasiliensis Lam. as natural agent in the development of functional foods and nutraceuticals.

title: Trends of rainfall and temperature in Northeast Brazil

description: ABSTRACT For climate change scenarios, there is a high degree of complexity, with impacts on the future availability of water resources. In this context, studies related to changes in rainfall time series are essential in order to identify environmental vulnerability. The objective of this study was to analyze trends in the rainfall regime, number of rainy days and temperature for stations located at different continentality and altitude conditions in Northeast Brazil. Meteorological data of the Instituto Nacional de Meteorologia were used, being classified according to the location in relation to the continent: coastal strip (14 stations), strip of 150-300 km up to 300 m altitude (14 stations) and above 300 m (five stations), between 400 and 600 km from the coast up to 300 m (four stations) and above 300 m (eight stations). All the 45 stations used have a historical series with a data period of more than 30 years. The trend of rainfall and rainy days was obtained through the Mann-Kendall and regression analyses, at significance levels of 0.01 and 0.05, respectively. There were trends of reduction in the number of rainy days, in the coastal strip, as well as reduction in rainfall and rainy days, both in the strip of 150-300 km from the coast and in the Sertão region, with no significant effect of continentality in the strip of 400-600 km from the coast. For temperature, except for Maceió, AL, Brazil, there is a trend of increase in near future.
