Abstract
O Exame Nacional de Desempenho de Estudantes (ENADE) compõe uma das bases avaliativas do Sistema Nacional de Avaliação da Educação Superior e tem como principal propósito, avaliar o rendimento dos estudantes a partir da sua formação nos cursos de graduação. Por isso, este trabalho identificou a possibilidade de se basear nesses resultados para aprimorar os processos de ensino-aprendizagem. Para tanto, este artigo apresenta o planejamento, criação e avaliação de uma plataforma de aprendizagem Web responsiva, baseada no ENADE e que utiliza elementos de gamificação com o propósito de aumentar o engajamento dos estudantes. O software foi avaliado, por meio de questionários de aceitação tecnológica, aplicados com 38 usuários e que apresentou resultados promissores, com média geral de 4,71 entre 5 pontos possíveis.

Abstract
This study intends to understand whether hotels should choose to surprise through a discount or a surprise gift. The experiment consisted in identifying whether there were differences in satisfaction and delight, according to the associated treatment (no surprise, surprise discount, or gift). With this purpose, a fictional hotel website was created for participants to simulate a reservation. Through the analysis of the experiment, the impact of surprise on customer satisfaction was confirmed. It was also found that, in the hospitality industry, a gift has a higher impact on satisfaction than a discount. When analyzing the guest delight, the results differ from what is stipulated in the literature (which points to the significant impact of surprise in this measure). It was concluded that between the two promotion tools, only the gift can significantly increase customer delight. This study demonstrates the importance of understanding the concept of surprise according to different industries. It also points to the importance of identifying the best methods to surprise customers, as different methods may lead to different results. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
Almond trees in Portugal are susceptible to aphid infestation, which can result in reduced fruit production. To effectively tackle this issue, the combination of remote sensing (RS) data and machine learning (ML) classifiers can be used to accurately detect the presence of aphids. This study focuses in the implementation of ML classifiers and RS data analysis to identify aphids on almond trees, using high-resolution multispectral data collected through an unmanned aerial vehicle (UAV) in a Portuguese almond orchard. Four ML classifiers, kNN, SVM, RF and XGBoost, were employed and fine-tuned using vegetation indices derived from spectral data. The results revealed that the SVM classifier achieved an overall accuracy (OA) of 77%, followed by kNN with an OA of 74%, while XGBoost and RF achieved OAs of 71% and 69%, respectively. Consequently, this study demonstrates the viability of employing RS data and ML classifiers for aphid identification in almond orchards.

Abstract
The complexity of automotive supply chain management presents significant challenges, demanding rigorous coordination of tasks to ensure efficiency in its operations. This chapter examines the potential benefits of adopting blockchain technology in supply chain management. The study employs a case study methodology, focusing on a prominent European automotive company that, compared to its major competitors, appears hesitant to integrate blockchain into its supply chain management practices. The analysis relies on secondary data and utilizes a range of strategic analysis tools to gain deeper insights into the advantages that blockchain technology could offer in supply chain management. Based on the findings, this chapter offers 12 strategic recommendations pertaining to blockchain technology, which can aid the company in addressing various management issues by enhancing security, efficiency, and technological advancements. © 2024, IGI Global.
