There is huge speculation that autonomous vehicles (AVs) will improve urban traffic conditions by enhancing mobility, reducing emissions, and bringing safety. However, AV public acceptance represents a key factor to this technology's success. This paper aims to present a brief review of public perceptions of AVs and focuses on how factors such as demographics, safety, ethics, liability, and COVID-19 pandemic can impact this mobility device’s acceptance. Overall, it was found that young and more educated males are more likely to adopt AVs, whereas concerns about safety, ethics, and liability can impact negatively on people’s perception of them.
A inserção do skate como modalidade esportiva nos Jogos Olímpicos de Verão de 2020 lança luz sobre uma prática costumeiramente marginalizada no Brasil. A fim de avaliar o impacto do skate nos Jogos Olímpicos no interesse dos brasileiros, este estudo analisou os volumes de buscas no Google Trends e os comparou com dados globais. Após coleta e tratamento dos dados, identificou-se que o interesse médio pelo termo skate no Brasil antes dos Jogos Olímpicos era 4,5 vezes inferior à média mundial. Já durante o evento, o Brasil foi o país que mais se interessou pelo assunto — potencial consequência da conquista de medalhas por atletas brasileiros. Todavia, uma crescente popularidade do skate no Brasil evoca as dificuldades enfrentadas pelos praticantes da modalidade no país, como a falta de regulamentação. O Código de Trânsito Brasileiro não reconhece o skate como um veículo — expondo, assim, os usuários a riscos nas vias.

There are several catastrophic events that can happen in a city. Occurrences that present themselves with different origins and magnitudes. In the midst of this, the organization and preparation of municipalities in order to avoid or mitigate disasters become fundamental. In this context, some of the strategies involve consensus based on previous experiences added to studies and surveys supported by large organizations. From this, concepts were raised that relate before, during and after possible events. For a general assessment, it is essential to report information related to terms such as 'Resilience' and 'Humanitarian Logistics'. Within this perspective, the municipality of Juiz de Fora (MG) was studied as a practical case, considering the measures taken by the city in order to avoid catastrophes. Evaluating the possible solutions that can be used in the local context, it was demonstrated that, through the integration between different sectors of the public administration, it is possible to transform the reality of the residents of the region, bringing them greater security.
