‘Do we all get a PhD?' Attempting emancipatory research relating to disability in an academic environment. Relating to disability in an academic environment

Within the model of emancipatory research, the researcher is situated as one member of a team. They are often conceptualised as providing methodological tools and skills to others involved in the research project but the definition of topic, data analysis and dissemination is presented as a joint enterprise. This model of research (deliberately) contradicts with the view of the expert researcher prevalent within higher education establishments and particularly with the individualised construction of research degrees such as PhDs which requires a thesis to be the exclusive product of one individual. The paper discusses attempts which have been made to reconcile the tensions inherent in adopting an emancipatory model within an academic environment including our own experiences of researching and supervising a doctoral thesis on citizenship and disability. The project is led by an advisory panel of disabled people who are involved in the preparation, selection and analysis of the interviews and pragmatic aspects of attempting such an emancipatory model of research from the viewpoint of the entire research team. It raises the question as to whether such models can only be completely adhered to in particular, probably non-academic settings

Invariant states and rates of Convergence for a critical fluid model of a processor sharing queue

This paper contains an asymptotic analysis of a fluid model for a heavily loaded processor sharing queue. Specifically, we consider the behavior of solutions of critical fluid models as time approaches \infty. The main theorems of the paper provide sufficient conditions for a fluid model solution to converge to an invariant state and, under slightly more restrictive assumptions, provide a rate of convergence. These results are used in a related work by Gromoll for establishing a heavy traffic diffusion approximation for a processor sharing queue

A remote sensing evaluation of potential for sinkhole occurrence

The relationship between lowering of the water table and sinkhole development in Pierson and in Hillsborough County, Florida was investigated. The locations of recently developed (1973) collapses were examined with respect to lineaments or fracture traces that are expressed in the terrain and visible in aerial photography and satellite imagery. It was anticipated that these relationships would provide the basis for establishment of criteria for mapping those land areas that have the greatest potential for sinkhole development. A very good correlation was found between mapped lineament intersections and known location of sinkhole occurrences for both study areas. This indicates that lineament and fracture trace mapping may be very useful in locating zones with the greatest potential for sinkhole development. It is further shown that this information is quite beneficial in land use planning applications
