The Scottish Qualifications Agency (SQA) is charged with the task of overseeing school–based qualifications in Scotland. However, for the 2000 exam diet the SQA failed to produce either timely or accurate exam results. The events surrounding this failure, accompanied by the responsible minister's explanation of his own actions and inactions, brought to the fore issues of responsibility and accountability. The unresolved nature of accountability and responsibility within government, particularly in relation to non–departmental public bodies (NDPBs), became apparent as the inquiries into the SQA took evidence. Utilizing the SQA as a powerful example, this article explores the problematic structures of accountability and responsibility that exist between NDPBs and ministers.  相似文献

This study examined the knowledge and perceptions of juvenile justice officials about selection bias and other causes associated with minority overrepresentation. In-depth interviews were conducted with officials working at major decision-making levels in the juvenile justice system of the Commonwealth of Kentucky. Almost half of the officials did not perceive selection bias to be present in the system. The other officials were divided in their beliefs about the possibility that selection bias could be the result of isolated incidents of discrimination as opposed to systematic race and class biases in the society and juvenile justice system. The study concluded that most judges, county attorneys, police officials, and some court designated workers thought that the system was fair and equitable.  相似文献

A collaborative 18 month study was conducted within 4 protected mangroves areas in Airai State, Southeast Babeldaob and the Republic of Palau with traditional men and women groups. Water quality, forest structure, and the size distribution and relative abundance of the mud crab, Scylla serrata and the clam Anodontia edulenta were studied. Water quality parameters differed significantly between sites as follows: pH (F=16.8; df=3,138; p〈0.000), turbidity (KW-H=22.07; df=3,162; p〈0.0006), salinity (F=19.8; df=3,366; p〈0.000), dissolved oxygen (KW-H=13.4; dr=3, 169; p〈0.0012) and temperature (F=4.33; df=3,157; p〈0.006). The total mean density of all trees was 2,077±225 stems ha^-1 and differed significantly between sites (KW-H=9.3; df=3; p〈0.02). The total mean basal area was 18.9±2.76 m^2ha^-1 and differed significantly between sites (KW-H=36.2; df=3; p〈0.000). The total mean volume of all trees was 679 m^3ha^-1 ± 201 m^3ha^-1. The total mean density of saplings was 1,234 ± 297 saplings ha^-1. The mean percent tree canopy cover significantly differed between sites (F=3.3; df=3, 32; p〈0.02). Mean soil elevation decreased at sites 1 and 4 and increased at sites 2 and 3. The mean soil accretion was greater at sites 1 and 3 than sites 2 and 4. The mean weight for all crabs was significantly different between sites (F=3.2; df=3, 178; p〈0.02). The mean weight for 55 females was 0.62 g ± 0.04 kg (SE) and differed significantly between sites (F=4.2; dr=3, 51; p〈0.01). The mean weight for 157 males was 0.75 ± 0.04kg (SE). The mean carapace width (CW) for all crabs was 14.30 ± 0.20 cm (SE). The mean carapace width (CW) for 56 females was 14.4 ± 0.35cm (SE) and significantly differed between sites (F=4.6; df=3, 52; p〈0.006). The mean carapace width (CW) for 157 males was 14.3 ± 0.21 cm. The mean CPUE for all sites was 0.48 ± 0.04 crabs trapl night^-1 (SE) and significantly differed between sites (F=2.9; df=3, 77; p=0.04). A total of 21 tagged crabs were recaptured in the same area they were initially tagged, of which 3 male crabs had molted. A male was recaptured in the same trap 180 days after capture at Site 1 ; the carapace width increased by 3.6 cm and a weight increase of 0.75kg. A single A. edulenta was found in the protected areas. Clams harvested in Airai State outside the protected areas were significantly smaller than clams harvested in northwest Babeldaob (F=14.8; df=1, 198;p〈0.0002). Crab fishers and the community recommended a harvest ban on female crabs, enforcement of existing 6inch CW harvest size limit, further investigation of point sources of coliform bacteria and sediment pollution and a harvest limit on mangrove trees.  相似文献
