The paper deals with the paradigm of factbased modelling and its relation to value-oriented business process modelling. Fact-based modelling is a conceptual approach for information systems modelling. It can be also considered as a synonym for object-role modelling (ORM). Value-oriented business process modelling represents resource-event-agent (REA) ontology and its REA value model. Analysing ...

In the discipline of accounting, the resource-event-agent (REA) ontology is a well accepted conceptual accounting framework to analyze the economic phenomena within and across enterprises. Accordingly, it seems to be appropriate to use REA in the requirements elicitation to develop an information architecture of accounting and enterprise information systems. However, REA has received comparativ...

OBJECTIVE To study HLA class I and class II association in Tunisian patients with reactive (ReA) and undifferentiated arthritis (UA). METHODS The study included 17 patients with ReA defined according to the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA), 11 patients classified as having undifferentiated arthritis and 100 unrelated healthy controls. HLA class I a...

Bacterial enteric infections cause substantial morbidity in the United States both from acute illness and sequelae that follow. Reactive arthritis (ReA) is a poorly defined term that is used to describe a variety of rheumatologic phenomena that may occur after Salmonella, Shigella, Campylobacter, and Yersinia infection, as well as other types of infections (eg, Chlamydia). This review focuses o...

A protein antigen from an Eimeria protozoan has recently been reported to induce antitumor activity in mice. This activity most likely results from the strong induction of interkeukin-12 (IL-12) and gamma interferon (IFN-gamma), which are also essential factors in the establishment of protective immunity against viral infection. We evaluated recombinant Eimeria antigen (rEA) as a potential immu...

OBJECTIVES To study the incidence and clinical picture of Shigella associated reactive arthritis (ReA) and the arthritogenicity of various Shigella species in the population. METHODS A questionnaire on enteric and extraintestinal, especially musculoskeletal, symptoms was sent to 278 consecutive patients with Shigella positive stool culture and to 597 controls. Analysis of self reported muscul...

BACKGROUND The pathogenesis of reactive arthritis (ReA) apparently involves aberrations in innate immune functions such as monocyte tumour necrosis factor (TNF) generation. OBJECTIVE To investigate TNF production in healthy subjects with previous yersinia triggered reactive arthritis. METHODS The study comprised HLA-B27 positive subjects with previous reactive arthritis (B27+ReA+), and B27+...

Quantification of ethanol by a radiative energy attenuation (REA) technique was evaluated and compared with results by gas-liquid chromatography (GLC) and by the Du Pont aca. Within-assay CVs were less than 5.5%. Between-assay CVs ranged from 1.9% to 6.0% for serum and blood controls at concentrations of 0.5, 1.0, and 2.5 g/L. We observed no cross reactivity with methanol, isopropanol, or aceto...

Determination of cholesterol by a radiative energy attenuation (REA) technique was evaluated and compared with results obtained by the Boehringer Mannheim High Performance Cholesterol Assay and the Du Pont aca. Within-assay and between-assay CVs for the REA method, for two sets of controls, were both less than 5%. We observed no interference with lipemic samples. Analytical recovery averaged 10...

Ripple Effect Analysis (REA) is an iterative process used to ensure consistency and integrity after changes are made to software. Many techniques, including program slicing, have been proposed to be used in this process with varying degrees of success. This paper shows how program slicing can be used in the REA process. Specifically this paper demonstrates the need of both forward and backward ...
