The impact of the Decision Support Systems (DSS) on the organizational intelligence and structure and on the strategic decisions was examined in the paper. Nowadays there is an increasing demand for investments on Information Technology (IT) due to the higher complexity of this field in the global market. Nevertheless, measurement of that perception, especially for the Brazilian reality, is little known. This study aims to analyze the relation between the use of DSS by executives of highest organization levels and their perceptions of the quality of information delivered, decision making speed, enhancements in organization learning and strategic management, and differences in involvement with subordinates. The theoretical model proposed by Leidner, Elam and Corrales (1995) and Leidner and Elam (1999), the main theoretical foundation of the paper, was adapted to the Brazilian reality and extended. We conducted a survey with executives of the 1200 biggest companies in Brazil, evaluating the executives' perceptions. The main results of the paper confirmed past studies and added new dimensions to the benefits provided by the use of information systems, such as the organization learning principles and the strategic planning process. The paper contributes to the theoretical development of information systems and decision-making fields and with organization management, providing knowledge to support the evaluation of the values created by using Information Systems (IS).
Esforços em diversas áreas do conhecimento científico, sobretudo na de infodemiologia, têm se dedicado a propor soluções para os problemas socioeconômicos provocados pela pandemia da SARS-CoV-2 e do isolamento social decorrente dela. O estudo de insights sobre como a COVID-19 está se disseminando em determinadas regiões é uma alternativa eficaz para lidar com este desafio. Este artigo analisa, de forma exploratória, a relação entre os dados publicamente disponíveis de índices relativos de busca por palavras-chave no Google Trends® e os dados governamentais de notificação de infectados pela doença em Minas Gerais, Rio de Janeiro e São Paulo. Em uma análise longitudinal, constata-se que as pesquisas por “Teste de COVID” e “Sintomas de COVID” são explicativas para o número de casos notificados nestas localidades. Este estudo fornece percepções iniciais para auxiliar pesquisas no uso das buscas online, relacionadas à doença, como variáveis explicativas adicionais a modelos preditivos, resguardadas suas devidas limitações.
