title: Evaluation of classification techniques for identifying fake reviews about products and services on the internet

description: Abstract: With the e-commerce growth, more people are buying products over the internet. To increase customer satisfaction, merchants provide spaces for product and service reviews. Products with positive reviews attract customers, while products with negative reviews lose customers. Following this idea, some individuals and corporations write fake reviews to promote their products and services or defame their competitors. The difficulty for finding these reviews was in the large amount of information available. One solution is to use data mining techniques and tools, such as the classification function. Exploring this situation, the present work evaluates classification techniques to identify fake reviews about products and services on the Internet. The research also presents a literature systematic review on fake reviews. The research used 8 classification algorithms. The algorithms were trained and tested with a hotels database. The CONCENSO algorithm presented the best result, with 88% in the precision indicator. After the first test, the algorithms classified reviews on another hotels database. To compare the results of this new classification, the Review Skeptic algorithm was used. The SVM and GLMNET algorithms presented the highest convergence with the Review Skeptic algorithm, classifying 83% of reviews with the same result. The research contributes by demonstrating the algorithms ability to understand consumers’ real reviews to products and services on the Internet. Another contribution is to be the pioneer in the investigation of fake reviews in Brazil and in production engineering.

title: The brazilian logistics service provider on the internet

description: Abstract: The attention of Logistics Service Providers (LSPs) to market movements and trends is fundamental to winning accounts, as well as avoiding problems and keeping customer companies. In this context, the primary purpose of this article was to identify, characterize and analyse the types of logistics outsourcing in Brazil, to evaluate the LSPs concerning the capacity of integration in the supply chains (SC), through the positioning and offer of services that they adopt on their websites. Therefore, the theoretical discussion pointed out the importance of websites for organizations, considering the company's website as an essential communication channel. The study researched 154 websites of these providers in Brazil aiming to understand if the attributes and competencies disclosed are aligned with the theory. The results show that the majority (59%) of LSPs in Brazil are unable to articulate and present their skills in the same way that they are discussed in theory.

title: Study of the rate of generation of waste from construction in new works in the city of Ribeirao Preto-SP

description: Abstract: In the construction industry, many waste products are produced most part of the time, because they do not have a correct end, end up causing strong impacts on the environment. To this end, CONAMA Resolution No. 307/2002 and its amendments thereafter determine the guidelines for the management of civil construction waste appropriately. In this context, this article aims, through a quantitative study, to identify the situation of civil construction waste, called here as RCD, in the city of Ribeirao Preto, determining the amount of waste generated through two parameters; licensed areas and volume disposed of at authorized locations, from a generation rate of 183.28 kg/m2, generating 1,112.35 t/day and 561.98 t/day respectively. The work sought to relate the values and obtained a per person generation of 1.24 kg/inhab × day. Thus, the article identified and measured the generation of construction waste in the city of Ribeirao Preto-SP, providing subsidies and information for comparisons with existing bibliography.

title: A reliability engineering case study of sugarcane harvesters

description: Abstract: The present study aimed to analyze factors associated with the equipment failures of the sugarcane harvester, whose machineries has high importance in the harvest process and cost involved. Part of the data was originally provided by a company located in the countryside of Sao Paulo State, from two machines, collected from January 2015 to August 2017, corresponding to 2.5 crops. The overall dataset was obtained from three different sources: a stop-tracking system, which provides the track of a preventive and corrective maintenance historical of the analyzed equipment; telemetry data of the equipment, captured through embedded computer systems, installed in the machine’ type under study, which provide information on its operation; and meteorological data from the Brazilian National Institute of Meteorology. Multivariate analyzes were used such as principal components and multiple regression models, therefore creating a model for prediction considering the next equipment’ break, then pointing to causes of process failures. Thus, the results point to some improvements concerned with individualized reliability scheme in order to reduce the number of corrective stops given the equipment.

title: Information security in healthcare supply chains: an analysis of critical information protection practices

description: Abstract: Because of their vital role and the need to protect the patient information, interest in information security in Healthcare Supply Chains (HSCs) is growing. This study analyzes how decisions related to information security practices in HSCs contribute to protecting patient information. Eleven semi-structured interviews were performed. The interviewees were managers from Brazilian HSC organizations. Four dimensions and 14 variables identified in a literature review were used to perform categorical content analysis. The findings suggest organizations, while aware of their critical information and internal processes, lack the necessary metrics to measure the impacts of possible failures. It seems organizations tend to invest in standard security measures, while apparently ignoring the specificity and complexity of information in HSCs.

title: The roles related to performance measurement systems use: a study based on clusters statistics analysis

description: Abstract: The performance measurement systems (PMS) have been studied over the last ten years, but this is still a very important research topic for companies and it keep being studied nowadays, because such systems help in decision-making, they allow monitoring and control indicators, and to assist business and operations strategy realization. The recent studies on PMS mostly are on reviewing their concepts and definitions, models, frameworks, design and implementation recommendations, etc. Based on a study oriented to PMS use described by roles to be played, this article aims to discuss the interrelationships between the roles of a performance measurement system, to cluster them and to formulate recommendations for their adoption and proper use. Thus, a survey collected and analyzed the perception of business representatives, who are able to express their agreement levels for PMS roles and use. Data are analyzed by using cluster analysis technique where the roles forms four groups, which can be confronted with the findings of related works from PMS literature. From the groups formed, it is possible to indicate four main domains of recommendations: to assure the alignment between strategic management of operations and its performance, promoting and improving the overall efficiency and effectiveness of the business operations results; to produce positive changes in organizational systems, processes and culture, developing the capacity to manage continuous improvement projects through integrated strategic management systems; to have a customer-oriented design approach; to be orientated and to manage stakeholders’ demands.

title: The role of formalization in the insertion of social indicators in the supply chain of the popular garnment sector

description: Abstract: Under the supply chain sustainability debates and seeking to reduce the theoretical gap related to the social sustainability dimension, this research aims to analyze the relation between formalization and the insertion of social indicators in the supply chain of the popular garment sector in Fortaleza-CE. Using the case study strategy, 20 interviews were carried out with enterprises, direct suppliers and outsourced suppliers to cover the direct supply chain. Hence, were analyzed three categories - social responsibility, health and safety, and supplier development - and their 15 indicators. The results indicate that the formalization impacts on the insertion of social indicators, mainly in the category of health and safety. In addition, it was identified the possibility of informal work, even in the formalized companies, which demonstrates the need for a new look at this variable. With empirical demonstration, this study contributes to the study of social indicators in the supply chain and draws attention to informal labour relations in the local context.

title: Location of ecopoints through integration p-medians model with geographical information system

description: Abstract: The configuration of logistics networks for waste oil and fats collection services is a strategic point of great importance, since their disposal contributes to a number of environmental disturbances, problems in sewage pipes and wastewater treatment systems. Starting from this premise, this paper proposes location of ecopoints in the city of Montes Claros-MG, capable of optimizing the collection of the waste oil and fats in all urban area of the municipality. This proposal of location was constructed in two stages: in the first, the collection network was constructed by integrating a location model of facilities with a geographic information system (GIS). It was possible to model a collection network in the city of Montes Claros - MG containing 87,748 points referenced by geographic coordinates and representatives of residential points considered as potential generators of these residues. During the creation of the model, due to the high density of the network and the low quantity of facilities (p), which causes limitation in the solution, it was observed the need for thematization of the map and consequently the network partitioning in zones, which allowed to determine the initial amount of installations that were to be found in the solution. Finally, an application in the native language of Transcad, GISDK, was developed with a programming interface that was developed to automate the process of integration of the model in the GIS. The model allowed the creation of 12 networks with densities below 12000 points, allowing gain in the solution of the problem.

title: Multiple dynamics of financialization in the automotive sector: Ford and Hyundai cases

description: Abstract: The financialization process in the automotive sector is growing and has affected the automakers in different ways. In this paper, we propose to study the different dynamics that involve financialization in the automotive sector by comparing Ford and Hyundai cases worldwide. To do this, we used indicators that aim to concretize the economic concept of financialization. They are the following: a comparison between sources of profitability; composition and shareholder acquisitions; business leaders; compensation payments to executives; dividend payments to shareholders; salaries and level of employment. These indicators showed a tendency of financialization in both automakers, but with different incidences in each one of these indicators. They have shown, for example, that while Ford's financial sector is more profitable than its productive sector, Hyundai's two sources of profitability are much more balanced showing significantly smaller differences than Ford's. The employment level indicator showed that while there has been a huge drop in the number of jobs at Ford in recent decades, at Hyundai there has been a reverse movement of expansion and hiring. The aim of this article is to discuss the financialization indicators in these two automakers, contributing to better knowledge about the automotive sector and collaborating with the research agenda of economic sociology and finance.
