Alternative media for public pedagogy: "Chief" concerns and human agency

To demonstrate how the growing influence of alternative media in civil society correlates with the rise of social movements and their influence on contemporary manifestations of resistance, this research uses critical ethnographic methodologies to document the narratives of alternative media producers in the pro-Indigenous and anti-“Chief” campaigns at the University of Illinois at Urbana-Champaign during the 2006-2007 school year. These narratives demonstrate not only the ways alternative media help transmit dissent by distributing information to diverse populations, but also the manner they facilitate contexts that influence identity formations and strengthen counter-cultural communal practices. Particular lineages of critical social theory are used to situate knowledge construction and social relationships within specific socio-historic contexts to approach issues of subjectivity, human agency, and resistance. These include the Frankfurt School for Social Research, the Birmingham Centre for Contemporary Cultural Studies, and the Brazilian education philosopher Paulo Freire, who emphasize criticality based on the engagement of ideological analysis, as well as developing capacities to critique and resist oppressive social and political relationships. Thus, this study argues for expanding traditional notions of literacy to include the ability to decode and produce media as a critical element of meaningful democratic participation.

Investigation of the hazards of substrate current injection: transient external latchup and substrate noise coupling

Substrate current injection is the origin of external latchup and substrate noise coupling. The trigger current for external latchup depends on the duration of the trigger event. A physics-based model is provided to model the effects of aggressor to victim spacing and orientation on transient triggering of external latchup. The latchup susceptibility of standard cell based designs is also investigated. Guard rings are used to reduce latchup susceptibility and to reduce the substrate noise coupled to sensitive analog circuits. In this work, the effectiveness of different guard ring topologies for the reduction of substrate noise coupling is also investigated.
