Instrumental measurement of the cognitive and emotional background of deception

Objectives The objective of this study was to evaluate the diagnostic performances of manual and instrumental measurement of reticulocyte percentage (Ret%), reticulocyte number (Ret#) and reticulocyte production index (RPI) to differentiate regenerative anaemia (RA) from non-regenerative anaemia (NRA) in cats. Methods Data from 106 blood samples from anaemic cats with manual counts (n = 74; 68 NRA, six RA) or instrumental counts of reticulocytes (n = 32; 25 NRA, seven RA) collected between 1995 and 2013 were retrospectively analysed. Sensitivity, specificity and positive likelihood ratio (LR+) were calculated using either cut-offs reported in the literature or cut-offs determined from receiver operating characteristic (ROC) curves. Results All the reticulocyte parameters were significantly higher in cats with RA than in cats with NRA. All the ROC curves were significantly different ( P <0.001) from the line of no discrimination, without significant differences between the three parameters. Using the cut-offs published in literature, the Ret% (cut-off: 0.5%) was sensitive (100%) but not specific (<75%), the RPI (cut-off: 1.0) was specific (>92%) but not sensitive (<15%), and the Ret# (cut-off: 50 × 10³/µl) had a sensitivity and specificity >80% and the highest LR+ (manual count: 14; instrumental count: 6). For all the parameters, sensitivity and specificity approached 100% using the cut-offs determined by the ROC curves. These cut-offs were higher than those reported in the literature for Ret% (manual: 1.70%; instrumental: 3.06%), lower for RPI (manual: 0.39; instrumental: 0.59) and variably different, depending on the method (manual: 41 × 10³/µl; instrumental: 57 × 10³/µl), for Ret#. Using these cut-offs, the RPI had the highest LR+ (manual: 22.7; instrumental: 12.5). Conclusions and relevance This study indicated that all the reticulocyte parameters may confirm regeneration when the pretest probability is high, while when this probability is moderate, RA should be identified using the RPI providing that cut-offs <1.0 are used.

Aim of this work – to set forth general principles of ground of efficiency of informatively-measuring technologies in the process of exploitation of objects of the real estate. Methodology. The method of substantiating the effectiveness of the restoration of the technical condition of real estate in the process of their operation is based on the use of information and measurement technologies to establish the technical condition of the object, which is a combination of information retrieval methods, instrumental measurement, analysis and processing of such information, technological and technical solutions to ensure the operational suitability of the facility in conditions of uncertainty. The method involves the formation of a repair strategy using information and measurement technologies based on the development of the life cycle of repairs and algorithms for selecting options for instrumental monitoring systems, choosing the procedure for studying the duration of measurement work, justification of labor and information technology costs and comparative assessment of total costs of real estate object. Results. It is established that measuring works are an integral part of the process of operation and repair work in its composition, which are carried out according to a single schedule of operation of the building and are part of repair work, and the frequency and volume of measuring, including geodetic work correlate with. To plan the volume of measuring work, their duration and labor costs are determined on the basis of existing time norms, and in their absence – by methods of technical rationing. Substantiation of the effectiveness of information and measurement technologies in the operation of real estate is performed by comparative assessment of total costs during the operational stage of its life cycle, taking into account the costs of implementing information and measurement technologies, that is the set of processes for obtaining information by instrumental measurement and processing ‘effective conclusion on the technical condition of the property. The scientific novelty of the obtained results is in the development of general principles for substantiating the effectiveness of information and measurement technologies in the operation of real estate. The practical significance lies in the improvement of standard solutions for the choice of composition and content of information and measurement technologies, taking into account their impact on the duration and labor costs of all types of repairs and reconstruction.
