Landfast Legalities And Institutional Erosion: Assembling Alaska Coastal Governance At The Melting Edge Of The Anthropocene, Nicholas J. Parlato

Interdisciplinary Studies

Anthropocene discourses raise questions about the political agency of nonhuman nature and the error of human exceptionalism, blurring distinctions between the subjects and objects of environmental governance. In the Arctic, the environment’s capacity to determine how and what kind of activities can take place has long existed in tension with the legal and political systems imposed by colonial powers. How can governance and decision-making for destabilized socionatural communities be reconceived from a more-than-human perspective? Through the lenses of assemblage thinking, posthumanism, and Indigenous law, this dissertation interrogates conventional approaches to understanding and governing the Arctic and, focusing on the history …

Educational Data Mining Techniques To Analyze Student Behavior In A Learning Management System, Mohamad Ali Bin Baba

Dissertations

This study identifies course-level patterns of LMS use in fully asynchronous graduate engineering management courses and examines the relationships between LMS use, course type, student satisfaction, and performance. Using the Community of Inquiry (CoI) framework and Moore’s interaction types, LMS metrics were mapped to learner–content, learner–learner, and learner–instructor interactions and clustered with k-means across nine courses.
