Not Quite Foreign, Never Fully Belonging: Racialization Of Southbound Policy Students In Taiwan, Garima Jha Aug 2026

Not Quite Foreign, Never Fully Belonging: Racialization Of Southbound Policy Students In Taiwan, Garima Jha

Journal of Comparative & International Higher Education

This paper critically examines how race and racialization shape the socio-cultural adjustment experiences of international students from New Southbound policy (NSP) countries in Taiwan. Drawing from a qualitative part conducted for my master’s thesis, which explored the coping strategies and adjustment processes of seven students from Southeast and South Asia through semi-structured interview, I reframe the data to center race as an analytical lens using the conceptual framework proposed by Glasgow (2009) which explains that racialization as the process through which social meanings are attached to perceived cultural or bodily differences, creating and maintaining hierarchies among groups. and Brondolo et …

Race, Racism, And Racialization In International Higher Education: A Transnational And Mobility-Aware Approach, Benjamin Denga, Louise Michelle Vital Aug 2026

Race, Racism, And Racialization In International Higher Education: A Transnational And Mobility-Aware Approach, Benjamin Denga, Louise Michelle Vital

Journal of Comparative & International Higher Education

Race, racism, and racialization are increasingly recognized as central to understanding inequality in global higher education. Yet dominant frameworks in comparative and international higher education remain nationally bounded and citizenship-centered, offering limited insight into how race operates under conditions of mobility, legal temporariness, and transnational governance. As internationalization intensifies through student mobility, cross-border partnerships, and global knowledge circulation, racialized experiences are shaped by visa-dependent status, differential protection, global racial imaginaries and discourses, uneven or unequal geopolitical relations and institutional logics of internationalization (including marketization, risk management and revenue extraction). In this conceptual article we argue that race and racialization in …

Generative Ai For Decision Making In The Manufacturing Systems, Xingyu Li Aug 2026

Generative Ai For Decision Making In The Manufacturing Systems, Xingyu Li

MMRL-XMO Industrial Seminar

Manufacturing systems increasingly demand real-time, multi-objective, and human-aligned decision-making that existing approaches cannot provide. In this study, we introduce the Generative Manufacturing System (GMS), a paradigm that reframes manufacturing decisions as samples from a learned conditional distribution, replacing inference-time search in the existing optimization-based approaches. Two instantiation examples are presented in manufacturing decision-making, including layout design and production scheduling, using domain-adapted diffusion models conditioned on operational constraints and human preferences. Experiments demonstrate 100% feasibility, near-zero objective matching error, and 25x decision making speed gain, establishing generative AI as a scalable, efficient, and human-centric decision-making engine for modern manufacturing systems.
