There is a high prevalence of traumatic brain injury (TBI) in prisoners, but screening tools for identifying TBI in female prisoners are not readily available. Using a cross-sectional design, the psychometric properties of the Brain Injury Screening Index (BISI) were investigated in a closed United Kingdom female prison. Purposive sampling comprised 56 females. Assessment included clinical interview, the BISI, self-report measures of mood, and a battery of measures of cognitive functioning. Seven of the 10 clinical indicators on the BISI met test–retest reliability criteria. Two of the three BISI summary variables demonstrated correlations with questionnaires in the hypothesized directions; however, only two BISI variables were associated with cognitive functioning. Findings support further investigation into the validity and reliability of the BISI with a larger sample.
Exploration prospects in the Rathlin Basin depend in part upon the reservoir potential of sandstones in the Permo-Triassic. The sandstones are the deposits of alluvial fan, channel and floodplain environments; aeolian deposits may occur in the basal (Permian) part of the succession. Scattered outcrops around the basin margin in Ireland and Scotland, and boreholes in the deep part of the basin onshore Northern Ireland, allow determination of diagenetic history and reservoir quality.Cementation is dominated by very early pore-filling sulphate/carbonate, illite-smectite grain-coatings, and overgrowths of potassium feldspar. Other cements are haematite graincoatings, quartz overgrowths and kaolinite pore-fillings. The sulphates/carbonates occlude porosity, and the clays/feldspars reduce permeability by bridging pore throats. Even in the deepest parts of boreholes, porosities can be high owing to dissolution of cements and unstable grains. This secondary porosity has in some cases been occluded by kaolinite, particularly in shallow-buried marginal parts of the basin.Thick, coal-bearing Carboniferous and gypsiferous Mercia Mudstone Group sections onshore suggest that adequate source and seal rocks exist below and above the sandstones, respectively, thus enhancing the exploration potential of the basin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
