A plan for administrative computing at ANL FY1991 through FY1993

In July of 1988, Argonne National Laboratory management approved the restructuring of Computing Services into the Computing and Telecommunications Division, part of the Physical Research area of the Laboratory. One major area of the Computing and Telecommunications Division is Management Information Systems (MIS). A significant aspect of Management Information Systems' work is the development of proposals for new and enhanced administrative computing systems based on an analysis of informational needs. This document represent the outcome of the planning process for FY1991 through FY1993. The introduction of the FY1991 through FY1993 Long-Range Plan assesses the state of administrative computing at ANL and the implications of FY1991 funding recommendations. It includes a history of MIS planning for administrative data processing. This document discusses the strategy and goals which are an important part of administrative data processing plans for the Laboratory. It also describes the management guidelines established by the Administrative Data Processing Oversight Committee for the proposal and implementation of administrative computing systems. Summaries of the proposals for new or enhanced administrative computing systems presented by individual divisions or departments with assistance of Management Information Systems, to the Administrative Data Processing Oversight Committee are given. The detailed tables in this paper give information on how much the resources to develop and implement a given systems will cost its users. The tables include development costs, computing/operations costs, software and hardware costs, and efforts costs. They include both systems funded by Laboratory General Expense and systems funded by the users themselves

Thresholds for adding degraded tropical forest to the conservation estate

Logged and disturbed forests are often viewed as degraded and depauperate environments compared with primary forest. However, they are dynamic ecosystems1 that provide refugia for large amounts of biodiversity2,3, so we cannot afford to underestimate their conservation value4. Here we present empirically defined thresholds for categorizing the conservation value of logged forests, using one of the most comprehensive assessments of taxon responses to habitat degradation in any tropical forest environment. We analysed the impact of logging intensity on the individual occurrence patterns of 1,681 taxa belonging to 86 taxonomic orders and 126 functional groups in Sabah, Malaysia. Our results demonstrate the existence of two conservation-relevant thresholds. First, lightly logged forests (68%) of their biomass removed, and these are likely to require more expensive measures to recover their biodiversity value. Overall, our data confirm that primary forests are irreplaceable5, but they also reinforce the message that logged forests retain considerable conservation value that should not be overlooked

Prevalence and severity of clinical consequences of untreated dentine carious lesions in children from a deprived area of Brazil

Item does not contain fulltextDisadvantaged children suffer because tooth cavities are not being treated and their clinical consequences not being surveyed. The present study aimed to assess the prevalence and severity of clinical consequences of untreated dentine carious lesions in schoolchildren from a deprived area of Brazil and to investigate the determinants of the pufa index. A sample of 835 children aged 6-7 years, from six public schools, was examined by 3 calibrated examiners. Clinical consequences of untreated dentine carious lesions in primary teeth were diagnosed using the four codes of the pufa index: 'p' (pulpal involvement), 'u' (ulceration), 'f' (fistulae), 'a' (abscess). Effects of gender, age, school, history of extraction, and toothache on the prevalence of pufa codes were tested. The prevalence of pufa codes was 23.7%. The mean pufa score was 0.4 +/- 0.9. Code 'p' was the most prevalent (19.5%), whereas code 'u' was least prevalent (0.1%). Children with a history of extracted primary teeth due to caries had a 2.7 times higher chance to have a pufa code than children with no previous extraction. Children with toothache had a 5.6 times higher chance to have a pufa code than children without toothache. The prevalence of clinical consequences of untreated dentine carious lesions was moderate and the severity was low. The pufa index is an epidemiological tool complementary to existing caries indices aimed to assess dental caries. However, there appears to be no need to include code 'u' nor to score codes 'f' and 'a' separately
