Marcus Vinicius Barcelos Nogueira — 2023-06-26

The retail sector in Brazil has been making great strides in recent decades, going from revenue of R$224.3 billion to R$611.2 billion in 2021, a result that reflects 7.03% of the Brazilian World Domestic Product (GDP), being one of the most important sectors of the country's economy (ABRAS, 2022). Intense competition has been causing changes in the service offered by the sector, redefining traditional activities in order to attach characteristics of other formats or directing its activities to a more specific niche. This study aims to carry out a historical analysis of efficiency, from 2013 to 2022, of the retail chains listed in the 2022 ABRAS Ranking in the state of Rio de Janeiro, using the DEA (Data Envelopment Analysis) calculation. Through the analysis, it was observed that establishing a single criterion of organizational and operational performance based only on revenue results does not reflect the relative efficiency of each retailer. The results showed that of the 21 retailers presented in the ranking, only eight showed maximum efficiency in the year 2022. Three of these were positioned after the tenth place in the ABRAS 2022 ranking.

Cristian Mateus Pereira Gabriel — 2023-06-26

The study aims to analyze the relationships between behavioral and sociodemographic factors with the investment decision of Brazilian academics in business areas. In order to achieve the research objectives, descriptive research with a quantitative approach was used. The procedures used in the study were Survey survey research and Structural Equation Modeling (Structural Equation Modeling – SEM). The main results highlighted that academics have a positive perception about money, most of them save part of their monthly earnings. However, notice a significant portion that has an expense equivalent to the gain. As far as the results from the Structural Equation Model are concerned, all variables with the exception of salary are related to investment decisions. The exogenous variables curiosity/trust and socialization/family showed positive correlations in relation to investment decisions based on the investor profile. While risk aversion, education level and college period have a negative correlation with individuals' investment decisions. The study's contributions show how behavioral and sociodemographic factors interfere in individuals' investment decisions, in addition to demonstrating how knowledge can significantly act within individuals' everyday decisions. Factors such as socialization play a significant role in disseminating knowledge about finance among individuals

PSYCHOSOCIAL BACKGROUND TO THE USE OF SOCIAL MEDIA MARKETING AND ITS IMPACT ON BUSINESS

Luiz Henrique Lima Faria — 2023-06-26

International studies have focused on the use of information and communication technologies (ICTs) in the micro and small business sector. Micro and small enterprises (MSEs) sustain a fundamental role in the Brazilian and international economic scenario, contributing substantially to the social development of their countries. Based on the theoretical motivation founded on the need to understand the psychosocial factors that precede the use of social media marketing and its impact on business in the context of Brazilian micro and small businesses, as well as to make comparisons with correlated international studies, this study aimed to analyze the relationships among antecedent variables to the use of social media marketing and its impact on business in Brazilian micro and small businesses. To reach this objective, data were collected by means of a survey applied on a sample of 82 Brazilian MSEs. These data, after tabulated, were analyzed by the method of Structural Equation Analysis by Partial Least Squares (PLS-SEM), resulting in the non-rejection of the five hypotheses tested in this study. Thus, it was verified that the psychosocial variables Facilitating Conditions (CF), Compatibility (COM), Perceived Usefulness (UP), Cost (C), Perceived Ease of Use (FUP) are antecedent variables to the Use of Social Media Marketing (USE) and, the latter, antecedent to Business Impact (IN). From these results it was possible to make comparisons with international studies.

Gabriely Feliciano — 2023-06-26

Through the high competitiveness of the market and the high level of customer demand, companies sought opportunities to modernize their processes in order to offer quality products and services, with high flexibility and innovation content with lower cost and shorter delivery time. This research seeks to reduce the cycle time of the filling process of a cosmetics industry. For this, the DMAIC methodology was used to map the flow, measure and classify its variables, analyze the data to identify the root cause, propose improvements to the process and manage the performance indicators during the development of the activities. In order to achieve the proposed desires, this research relied on the application of the concepts and tools addressed by Lean Six Sigma. Based on the results, it was seen that there was a reduction in cycle time of 14.86%, where the current state that was 64.74 seconds became 55.12 seconds in the future state.

FIBER OPTIC IN COMPUTER NETWORKS

Luciano da Fonseca Calheiros — 2023-06-26

The connection of networks by fiber optics came to revolutionize communications, especially internet connectivity, providing more security, since the data encapsulated in fiberglass is not easy to be manipulated by humans without highly specialized machines and by having no interference in the signal within the fiberglass ensures high connection availability. This study aims to demonstrate the advantages and disadvantages of fiber optics compared to the metal mesh, which although more common is susceptible to external interference. The study was carried out with field research carried out in some companies in Porto Velho - Rondônia that migrated their connectivity with the internet, starting to use optical fiber It also has bibliographic research, especially those that point to a trend in the use of fibers in business activities. The research aims to show an overview of how managers perceive the advantages and disadvantages of deploying fiber optics at the expense of metal mesh and under what circumstances.
