关键词： Generative AI   sustained use   digital awareness   technology adoption   consumer behavior  

摘要： The rapid integration of generative artificial intelligence (AI) into consumer markets has significantly influenced how shoppers gather and process information. However, the factors that are associated with the sustained use of AI tools for shopping decisions remain underexplored. This study addresses this gap by employing a hybrid analytical approach combining 'Partial Least Squares-Structural Equation Modeling' (PLS-SEM) and 'Artificial Neural Networks' (ANN). We integrate the 'Uses and Gratification Model' with 'Dual-Process Theory' to explore how emotional and cognitive factors, such as enjoyment, perceived accuracy, and benefit, are related to continued reliance on generative AI. The model was tested with data from 397 users, and the findings reveal significant predictors of sustained use, underscoring the importance of these variables in contributing to long-term consumer interaction with AI technologies. These insights contribute to the broader understanding of how AI can sustainably support consumer decision-making.

关键词： Theories of space   comparative education   social topology   spatial-temporalities   beyond-human spatialities  

摘要： The aim of this article is to stretch spatial theorising in the field of comparative education. Among the different spatial theoretical approaches that have been explored in educational research in the last 10 years, we review social topology, spatial-temporalities, and beyond-human spatialities and how they have been used in comparative education research. To illustrate the potential of these approaches we then use them to analyse recent technological changes, shifts in governance, the impacts of global crises and the complicated ways in which they are spatially related to education. Through our analysis, we argue that comparative education research would benefit from making space for spatial theorising in relation to time, materiality, and the beyond-human, not only to better understand the world, but also to consider how education is ethically linked to the existential challenges humanity is facing today.

关键词： Politics of higher education   the signal - response mechanism   cengceng jiama   the Double First-Class University Initiative   discriminatory recruitment practices   China  

摘要： This article examines the politics of higher education in China drawing on empirical data collected from three elite universities listed in the 'Double First-Class University Initiative'. We investigate how a 'signal - response' mechanism, in which the country's top leaders signal broad policy goals and subordinate officials respond, works in China's higher education arena. To address the uncertainties caused by vague signals and avoid blame for failure to fulfil policy goals, a strategy involving a gradual downward increase of implementation pressure within the bureaucratic hierarchy, termed cengceng jiama ((sic)(sic)(sic)(sic)), has been adopted. Universities and their faculties/departments now establish their own 'up-or-leave' systems to remove underperforming researchers, apply more stringent criteria when assessing faculty members' publication rates, and discriminate against domestically trained PhDs when hiring. Consequently, faculty members, especially those in the younger generation, often experience high levels of anxiety, insecurity and inequality, which can hinder their development as scholars.
