title: Causes of cost overrun and financial impact on public works from risk management perspective

description: Abstract This paper aims to analyse the main causes for contracting additional services in public construction works, from a risk management perspective. A systematic literature review led to a new categorisation of the causes of cost overrun based on risk taxonomy. The field study involved an analysis of contracts for new and completed works at a public higher education institution. The Iramuteq software performed a lexical analysis of the justifications for the additions. The categorisation of the causes resulting from the literature review supported the definition of each risk category. The financial impact for each risk category was measured by quantitative analysis. The results indicate that the highest risk index corresponds to the project category, with 53% of addition frequency and 56% of financial impact. The contributions of this study involve the proposed model for analysis of the causes of cost overrun based on risk taxonomy and the association of lexical and documentary analyses to reduce subjectivity and improve the risk mitigation process.

title: Detection of Viable Salmonella Typhimurium and Staphylococcus aureus in Coalho Cheese by Real-Time PCR

description: Abstract Real-time PCR (qPCR) has been used for rapid identification of Salmonella Typhimurium and Staphylococcus aureus in dairy foods, but is unable to differentiate viable and unviable pathogens. Ethidium bromide monoazide (EMA), a DNA-intercalating agent, can detect only viable cells because selectively enter cells considered unviable and bind to their DNA, inhibiting its amplification during qPCR. The objective was to establish a protocol for detection of viable Salmonella Typhimurium and S. aureus, experimentally inoculated in coalho cheese, by the use of EMA combined with qPCR. The protocol was effective for the identification of viable Salmonella Typhimurium in coalho cheese but not for the S. aureus cells. Concentrations of viable Salmonella Typhimurium cells of 1 CFU/10 g of coalho cheese could be detected. The monoplex protocol enables the rapid and specific identification of viable Salmonella Typhimurium in coalho cheese, making it an alternative method for the quality and safety control of cheeses.

title: Phoretic mites (Rhinoseius spp.) in Apodiformes from Cerrado and Pantanal Biomes in midwestern Brazil

description: Abstract Nasal mites are commonly found in hummingbirds (Apodiformes). In most cases, endoparasitic mites were reported to parasitize the respiratory system, particularly the anterior nasal chambers, larynx, trachea, lungs, and the air and conjunctival sacs. However, some mites are only carried by hummingbirds, because flowers serving as a nutrient source for these small mites, such as for Apodiformes, a tropical nectar-feeding in their natural habitat. From August 2012 to May 2014, humminbirds were captured using mist nets, and examined for the presence of nasal mites (identified according to specific keys) in the Pantanal, and Cerrado biomes, from the Mato Grosso state, midwestern Brazil. Overall, 76 Apodiform specimens, from the Trochilidae family were captured, and 20 female nasal mites, identified as being from the Rhinoseius genus, were collected from eight hosts (10.5%), of the following species: Amazilia fimbriata, Amazilia versicolor, Eupetonema macroura, and Thalurania furcata. The Rhinoseius spp. has been reported on, in many ecosystems in the Americas, including Brazil, however, this is the first report on Apodiformes from the Pantanal biome. Phoretic mites are not responsible for direct damage to the population of Apodiformes, as they are not pathogenic. However, they compete for food with hummingbirds and decrease the quantity of food available in the environment. They also affect the reproductive dynamics of plants, feed on pollen, and interfere with the intricacies of the biodiversity where they live.

title: SOCIO-HISTORICAL RECOGNITION IN SIGNIFICATION CAPACITIES: CONCEPTS NEEDED TO OPERATIONALIZE LANGUAGE AND FOR RENDERING TEXT GENRE INTO A DIDACTIC TOOL

description: ABSTRACT This paper aims to discuss the operation of language titled socio-history recognition of the text genre, presented by Cristovão and Stutz (2011) within the framework of the signification capacities. Thus, we demonstrate the text traces used in order to analyze such operation of macro context level, which is related to the language general activity and, consequently, external to the text. Towards this end, we focus two productions of the horror short story genre taken as discursive diagnosis. The first one was developed by a 9th year pupil from high school in Guarapuava/PR; second one was created by a non-canonical writer and published in a horror stories website. Concerning to theoretical foundation, we are based on the studies of socio-discursive interactionism (BRONCKART, 1999), which discuss text genre and its relation to the actions of language and social activities under the lights of signification. Likewise, and mainly, we focus on studies of Cristovão and Stutz (2011) about proposing capacities of signification; on Stutz (2012) and Souza (2015) that address the relation between such capacities and its value for understanding language general activity, and in what way socio-history may be embedded in a particular text genre. Results reveal that socio-historical recognition is a cognitive protocol, which is responsible for developing capacities of recognizing and regulating values and social standards, constitution of symbolism, ideological frames materialized into discursive prototypes and, therefore, this operation of language grants connection between representations and their referents in the discursive structure.

title: Method for location-based production planning and control supported by BIM

description: Abstract The location-based approach for production planning and control has the advantage of making explicit the workflow throughout the production units, allowing to make a connection to the Last Planner System (LPS) and 4D BIM models. However, there are still some knowledge gaps, in both practice and research, regarding the implementation of this approach. Those gaps are mainly related to the application concepts and principles of the lean production philosophy, and their interaction with BIM functionalities. Indeed, it is necessary to develop studies not only on planning and control methods that consider the partially repetitive nature of construction activities, but also on the aspects related to work and product flow management. The aim of this study is to propose a Location-Based Planning and Control method supported by BIM and explore its interface with LPS. Design Science Research was the methodological approach adopted in this investigation and two empirical studies were carried out in real estate companies. The main contributions of the proposed method are related to the tools adopted, which can potentially contribute to improve the quality of information, mainly related to workflows, and to provide support to collaborative decision-making.

title: Microbiological quality of minimally processed vegetables commercialized in Brasilia, DF, Brazil

description: Abstract This study evaluated the microbiological quality of minimally processed vegetables commercialized in the city of Brasilia, DF, Brazil. A total of 32 samples of different vegetables were purchased from 10 supermarkets. In most samples (78.1%) the populations of psychrotrophic bacteria had a high count ranging from 106 to 108 CFU/g. Thermotolerant coliforms were found in all samples, with populations higher than 102 MPN/g in 15 samples (46.9%). After molecular analyses, E. coli was identified in 16 samples (50.0%) and Salmonella spp. in 4 samples (12.5%). S. aureus was found in 14 samples (43.8%), with counts higher than 103 CFU/g in 4 samples (12.5%). The results obtained in this study showed that 16 samples (50%) were unfit for consumption according to Brazilian legislation. These results indicated the need of adoption of better hygienic practices in the production of minimally processed vegetables to improve quality and microbiological safety.

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: Phytochemical screening, Sun Protection Factor (SPF) and sugar analysis of jatobá fruits (Hymenaea martiana Hayne): A native medicinal plant from the San Francisco Valley

description: Abstract Hymenaea martiana is a native medicinal plant from the Caatinga, but biochemical studies of the fruit have not yet been reported. Thus, this study aimed to determine sugars and secondary metabolites, as well as assess the sunscreen potential of H. martiana fruits. The fruits were collected in Petrolina and separated into pulp and seeds. The sugar analysis investigated the presence of glucose, xylose, cellobiose, arabinose and xylitol. The determination of secondary metabolites was made through phytochemical screening and sunscreen activity was assessed with the spectrophotometric method. In the fruit pulp, carbohydrates with a great biotechnological potential were identified. The substances found in the phytochemical screening showed great antioxidant, photoprotective and medicinal potential. With the pulp extract, the sun protection factor values obtained were not significant and for the extract from the seeds, the values were 4.54 ± 0.11. Although the values found are below the recommended, the fruit extracts of H. martiana could be used in future development of sunscreen products providing several benefits to the formulation.

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: 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.
