Overview and application of the AQEM Assessment System
Hydrobiologia, 2004Co-Authors: Daniel Hering, Otto Moog, Leonard Sandin, Piet F.m. VerdonschotAbstract:The main objective of the European Union (EU) funded project AQEM^1was to develop a framework of an Assessment System for streams in Europe based on benthic macroinvertebrates that fulfils the requirements of the EU Water Framework Directive. Initial Assessment methods for 28 European stream types and more generally applicable tools for stream biomonitoring in Europe were generated. The development of the System was based on a newly collected data set covering stream types in Austria, the Czech Republic, Germany, Greece, Italy, The Netherlands, Portugal and Sweden. Altogether, 901 benthic invertebrate samples were taken using a standardised multi-habitat sampling procedure and a large number of parameters describing the streams and their catchments was recorded for all sampling sites. From the stream and catchment characteristics measures of stress were derived. A large number of metrics was tested independently for each of the stream types, to identify the response of each metric to degradation of a site. This process resulted in up to 18 core metrics for the individual stream types, which were combined into a different multimetric index in each country. The multimetric AQEM Assessment System is used to classify a stream stretch into an Ecological Quality Class ranging from 5 (high quality) to 1 (bad quality) and often provides information on the possible causes of degradation. AQEM provides a taxa list of 9557 European macroinvertebrate taxa with associated autecological information, a software package for performing all the calculations necessary for applying the multimetric AQEM Assessment System and a manual describing all aspects of the application of the System from site selection to data interpretation.

An intelligent risk Assessment System for distributed construction teams
Engineering Construction and Architectural Management, 2005Co-Authors: H Shang, Chimay J. Anumba, Dino Bouchlaghem, John Christopher Miles, M Cen, M TaylorAbstract:Purpose – The paper proposes addressing the design and implementation of a web‐based risk Assessment System that enables remote project team members to assess the risks at the conceptual design stage.Design/methodology/approach – The prototype System is based on a client/server architecture and uses fuzzy logic and web‐based technology. A risk Assessment scenario is used to demonstrate the operation and benefits of the prototype System.Findings – The research found that the use of a web‐based risk Assessment System for distributed project team members has major benefits in terms of use of linguistic terms to express risk Assessment, ease of communication, ease of maintenance, and greater consistency, among others.Research limitations/implications – There is scope for enhancing the System through the development of a risk management module, improving the user interface and making specific provisions for different project types.Practical implications – The move in industry towards collaborative working prac...

the preterm prediction study a clinical risk Assessment System
American Journal of Obstetrics and Gynecology, 1996Co-Authors: Brian M Mercer, Robert L Goldenberg, A Das, A H Moawad, J D Iams, P J Meis, R L Copper, F Johnson, Elizabeth Thom, Donald McnellisAbstract:Abstract OBJECTIVE: Our aims were to develop a risk Assessment System for the prediction of spontaneous preterm delivery using clinical information available at 23 to 24 weeks' gestation and to determine the predictive value of such a System. STUDY DESIGN: A total of 2929 women were evaluated between 23 and 24 weeks' gestation at 10 centers. Demographic factors, socioeconomic status, home and work environment, drug and alcohol use, and medical history were evaluated. Information regarding symptoms, cultures, and treatments in the current pregnancy were ascertained. Anthropomorphic and cervical examinations were performed. Univariate analysis and multivariate logistic regression were performed in a random selection, constituting 85% of the study population. The derived risk Assessment System was applied to the remaining 15% of the population to evaluate its validity. RESULTS: A total of 10.4% of women were delivered of preterm infants. The multivariate models for spontaneous preterm delivery were highly associated with spontaneous preterm delivery ( p ≥ 20% risk) carried a 3.8-fold (nulliparous women) and 3.3-fold (multiparous women) higher risk of spontaneous preterm delivery than those predicted to be at low risk. However, the risk Assessment System identified a minority of women who had spontaneous preterm deliveries. The sensitivities were 24.2% and 18.2% and positive predictive values were 28.6% and 33.3%, respectively, for nulliparous and multiparous women. CONCLUSIONS: Although it is possible to develop a graded risk Assessment System that includes factors that are highly associated with spontaneous preterm delivery in nulliparous and multiparous women, such a System does not identify most women who subsequently have a spontaneous preterm delivery. This System has investigational value as the basis for evaluating new technologies designed to identify at-risk subpopulations. (Am J Obstet Gynecol 1996;174:1885-95.)
