The circular economy has become a topic of increasing relevance in the scientific field, and the literature on it has developed considerably in recent years. Therefore, a review is needed to contribute to the understanding of this term, which is under constant debate. This article aims to analyze scientific articles from qualitative and quantitative research approaches on the circular economy. The methodology used was a systematic review of scientific literature from Scopus and Web of Science; 67 scientific articles were systematized under inclusion and exclusion criteria related to the specific objectives sought. The results showed that there is still a long way to go in developing a theoretical framework that can be put into practice due to the divergence of existing perspectives or approaches, although its application to different fields of study is being considered. Likewise, its complex character is highlighted, while driving or limiting factors are observed. This research provides a theoretical contribution aimed at elucidating which implications of the circular economy need to be addressed in order to build a universal or flexible theory to understand what it means to plan for the implementation of the circular economy. In this way, it hopes to strengthen its practical application, which implies the need to create an overarching framework that can be adapted to different contexts and provide clear guidance on how to be part of the circular economy.
Sustainable consumption is a key concept in society and the environment due to its direct relationship with sustainable development; its importance lies in the decoupling of consumption and economic growth with environmental damage and its involvement with various behavioral disciplines and ecological concepts. Therefore, this research aims to analyze scientific articles linked to key perspectives of the concept under discussion. Due to the scope of the objective of systematizing the existing scientific literature on sustainable consumption in Scopus and Web of Science, a systematic review was carried out, including 104 scientific articles considering criteria that respond to the questions posed. It is concluded that sustainable consumption is a complex and nebulous concept whose theoretical fragmentation gives it breadth but generates overlapping concepts. Likewise, the link between the consumer and the circular economy and the difficulties behind such interaction was denoted. The complexity of being a green consumer in current times and the aspects that comprise it were also covered, and the importance, role, and tools of the government in sustainable consumption. Thus, it is expected to generate a consistent theoretical framework facilitating the creation of new applied research, considering the perspectives highlighted through this analysis.
Pedagogical strategies with technology have an impact on university academic teaching. Hence, there is a need to develop competencies that allow the efficient use of various digital resources. The present study validated through a confirmatory factor analysis the constructs proposed in the CUTIC-28 in a sample of 318 Peruvian university students. It was a quantitative approach research at a descriptive level and based on a non-experimental design. The results demonstrated, as reflected in each metric of the confirmatory factor analysis (CFA), the theoretical and empirical sustainability of the original questionnaire to assess the frequency and extent of ICT use in Peruvian university students; the set of data reported offers the certainty that it is a defensible and sustainable factorial model. The covariances and correlations between the dimensions and subdimensions are highly significant and positive, and, therefore, the factorial structure is confirmed by the sample data. The confirmed scale has adequate properties that allow it to be considered a valid and reliable measure in future research, even after adding other variables, such as gender, age, and type of university, among the variables of interest that show significant differences. The results also show that there is still a knowledge gap to be covered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
