Article: This article explores perspectives of time amongst young male inmates in prison and reflects on their cannabis use as a strategy that enabled them to manage their long sentences. The article considers the theoretical foundations of time and its association with punishment and prison, arguing that prison time is conceptually distinct from experiences of time outside prison. The overt external control over inmates' time and the limited resources available to make time 'flow' means time is experienced consciously in prison. This experience of time influenced the significance and function of the inmates' cannabis use, which helped them to control and manipulate the passing of their sentence.
This paper reports an environmental assessment of the geohazards and seep phenomena of the Mad Dog field area of the Gulf of Mexico. The Mad Dog block, centered on US GOM block GC782, is located on the Sigsbee Escarpment in the Green Canyon region of the Gulf of Mexico, approximately 310 km south of New Orleans. The study area covers approximately 120 km 2 and extends to water depths of 1300 m -2170 m. The available data included a deep-tow multibeam bathymetry and ultra-high-resolution 2D seismic grid in combination with satellite seepage slick interpretations from the greater Mad Dog area. Hydrocarbon seep phenomena and SAR slick data were cross-examined to determine a relationship; however although some large slicks had been mapped by SAR in the project area, the slick density was lower than anticipated and correlation to sea-bed manifestations was not always well defined. The seabed displayed substantial relief and steep gradients across a salt-related graben structure in the northwest, associated with several potential gas-related seismic wipeout features, and scarps in the central survey area. Substantial geohazards occur in the escarpment region with slope gradients up to 28 degrees and abundant evidence for mass transport deposits. The presence of strong currents that run parallel to the base of the escarpment at up to 1 ms -1 (Bryant et al. 2000) form mega furrows. Associated erosional processes in this current could mask seep phenomena and therefore be lost during bathymetry and subsurface analysis. Eight possible seep structures were observed in the region and one coned shaped mound interpreted as a mud/asphalt volcano. When correlating the locations to SAR slick data it was hard to conclusively establish a relationship between seeps and slicks due to the unknown currents. In order to reduce the uncertainty of slick and seep correlations, sea current data at various depths throughout the water column would be needed at the time of SAR capture, and access to any seafloor cores would help ground truth interpreted seepage phenomena. A better understanding of the plumbing system can only be gained from examining deeper-penetration 3D seismic data that was unavailable for this study.
