Hurricane Katrina devastated New Orleans, the Gulf Coast and the United States in August of 2005. While an emerging literature base details the consequences and lessons learned from Hurricane Katrina, a critical missing piece for understanding Hurricane Katrina American landfall is a rhetorical perspective. I argue a rhetorical perspective can significantly contribute to a better understanding of Hurricane Katrina’s implications for creating policy, community and identity. As a case study, I employ Kenneth Burke’s cluster analysis to examine the use of the label “Third World” to describe New Orleans, the Gulf Coast and the United States in the mass media coverage of Hurricane Katrina.

This research is a case study focused on the resocialization of prison gang members through the lens of the Texas Department of Criminal Justice’s (TDCJ) Gang Renouncement and Disassociation (GRAD) process, a nine-month, three-phase voluntary process whereby confirmed prison gang, or Security Threat Group (STG), members renounce their gang membership and disassociate from the gang while still incarcerated. The TDCJ implemented its gang renunciation process to relinquish its dependence on segregating confirmed prison gang members and to provide them a way to transition out of segregation. The GRAD process has been in place since 2000 with more than 2,600 offenders completing it, but little information, other than anecdotal evidence, is available to support or disprove its success or effectiveness at de-ganging and resocializing prison gang members for the long haul. Interviews were conducted with 16 individuals, including GRAD correctional officers and instructors, and law enforcement officers with known expertise and knowledge of prison gang investigations. A limited amount of extant aggregate-level data was provided by TDCJ to supplement the narratives in the qualitative analysis. Findings suggest that the identified goals of the process differ among GRAD staff and non-GRAD staff: GRAD staff focused on offender rehabilitation, and non-GRAD staff focused on gang renunciation. It was also found that resocialization and normative change can and do occur in the closed GRAD environment; however, no tracking mechanism exists to systematically and pro-actively monitor their behavior once they are released from GRAD to determine if they have internalized these new norms and values. Based on the interviews, it also appears that the length of time spent in segregation prior to renunciation renders the offender more grateful and appreciative, and, therefore, more likely to successfully complete the process. Finally, interviews with law enforcement reveal that, upon release to the broader community, these offenders may have renounced the gang – but not the crime. The dissertation ends with limitations to the study, recommendations for future research, and implications for social work. / text

As hard rock mining progresses into higher stress mining conditions through either late stage extraction or mining at depth, the rock mass is driven not just to the peak strength, but often well into the post-peak until complete ‘failure’ occurs and easier mining conditions become evident. Limited research has been accomplished in identifying the transition of the rock mass and its behaviour into the post-peak and this research investigates this behaviour in detail. As the rock mass progressively fails, fractures are initiated through intact rock and extension and shear failure of these and pre-existing features occurs. Associated with this failure are microseismic events, which can be used to give an indication of the strength state of the rock mass. Based on an analogy to laboratory testing of intact rock and measurement of acoustic emissions, the microseismicity can be used to identify, fracture initiation, coalescence of fractures (yield), localization (peak-strength), accumulation of damage (post-peak) and ultimate failure (residual strength) leading to aseismic behaviour. The case studies presented in this thesis provide an opportunity to examine and analyse rock mass failure into the post-peak, through the regional and confined failures at the Williams and the Golden Giant mines, both in the Hemlo camp in Northern Ontario, Canada. At the Williams mine, the progressive failure of a sill pillar region into the post-peak was analysed; relating the seismic event density, combined with numerical modelling and a spatial and temporal examination of the principal components analysis (PCA), to characterize the extent, trend and state of the yielding zone, which formed a macrofracture shear structure. Observations of conventional displacement instrumentation, indicates regional dilation or shear of the rock mass occurs at or prior to the point of ‘disassociation’ (breakdown of stable PCA trends) when approaching the residual strength. At the Golden Giant mine, the complete process from initiation to aseismic behaviour is monitored in a highly stressed and confined pendent pillar. The PCA technique, numerical modelling and focal mechanism studies are used to define significant stages of the failure process, in which a similar macrofracture structure was formed. Temporal observations of key source parameters show significant changes prior to and at the point of coalescence and localization.

As artists continue the long and storied lineage of Landscape, are there aesthetic responsibilities that come with representing the forces that afford you the capacity to do so? As we delineate spaces into places, endless interconnectivity into knowable “systems”, and living matter into thing based taxonomies, who do these delineations serve and with what intentions do we proceed? My studio art practice explores what it means to give form to our Former—the Former being that from which we came, the here and now, our explicit ecological reality, the stuff of what we call nature. In this way, the Former consists of all the powers at play that unthinkingly formed the vital life-forces that afford us our perceptive and creative capacities, and in doing so, precede us chronologically. The primary questions my creative practice posits are therefore: what does it mean to give form to our Former through creative applications? In doing so, is it appropriate to assume that we are returning the favor?
