This is a conceptual paper describing some of the conventional accounting concepts that are not in accordance with the paradigm of Islamic accounting. The paper concludes that the historical cost concept can be replaced by: current cash equivalent concept, historical cost and current value concepts (market selling price), current cost concept, historical cost concept in all (except for Zakat purposes) accounting calculations, current valuation concept, and fair value concept. Conservatism concept must be eliminated if historical cost concept is not used anymore. Matching concept can be replaced by asset-liability approach concept. Objectivity concept can be replaced by Zakat accountability concept. Stability of the monetary unit assumption can be replaced by gold or silver measurement, or Dirham currency, and going-concern assumption must be eliminated.展开更多

It is composed by a team of specialists that give a numerical value to many characteristics about flavours, synthesising a sensory analysis. Each expert answers questions about the aroma by assigning the adequate scores to each oil. The evaluation becomes objective by applying the statistical analysis of all the scores given by the participants: This is the definition of "measure" of Russell. The PT can be considered a true standard "metrological system" (considering the number of questions in the questionnaire), while the perceptions of the testers are the solicitations of it. To allow access to an expensive evaluation process by small companies, this work proposes to "disseminate" the properties of the metrology represented by PT. The results of the PT are arranged in an unsupervised artificial neural network (ANN), the Kohonen map, which represents the synthesis of self-organised output that has only the goal, in this paper, to make readable PT results. The dissemination process is obtained by the gas chromatographic (GC) analysis of each oil sample and through the identification of peaks corresponding to the perceptions. These signals are used for the training of the supervised Multi Layer Perceptron (MLP) ANN, with the back propagation algorithm, whose outputs are represented by the results of the PT. This procedure is exact a "metrological dissemination of a standard" and also the aim of the work: to classify EVOO without always resorting to PT.展开更多
