Similar Classification

There is a belief that any job evaluation method, when correctly applied to a series of jobs, will result in approximately the same rating classification as that supplied by any other method for the same job series. This study was aimed primarily at a determination of the extent to which a number of job evaluation methods, differing in methodology, and presently in use within South Africa on a national basis, would in fact supply similar classification. Correlation coefficients among the ratings supplied by participating organizations, in terms of points allocation for each job subsequent to evaluation according to job evaluation factors (raw point ratings), were unexpectedly high. These correlations ranged from 0,93 to 0,99, with an average of 0,98, indicating a remarkably high level of agreement. Correlations were properly transformed, and mean correlations of each organization with every other organization subsequently calculated. These mean correlations ranged from 0,96 to 0,98, once again indicating a high degree of commonality.

Two different procedures for the methylation of fatty acids (FAs) andtransfatty acids (TFAs) in food fats were compared using gas chromatography (GC-FID). The base-catalyzed followed by an acid-catalyzed method (KOCH3/HCl) and the base-catalyzed followed by (trimethylsilyl)diazomethane (TMS–DM) method were used to prepare FA methyl esters (FAMEs) from lipids extracted from food products. In general, both methods were suitable for the determination ofcis/transFAs. The correlation coefficients (r) between the methods were relatively small (ranging from 0.86 to 0.99) and had a high level of agreement for the most abundant FAs. The significant differences (P=0.05) can be observed for unsaturated FAs (UFAs), specifically for TFAs. The results from the KOCH3/HCl method showed the lowest recovery values (%R) and higher variation (from 84% to 112%), especially for UFAs. The TMS-DM method had higherRvalues, less variation (from 90% to 106%), and more balance between variation and %RSD values in intraday and interday measurements (less than 4% and 6%, resp.) than the KOCH3/HCl method, except for C12:0, C14:0, and C18:0. Nevertheless, the KOCH3/HCl method required shorter time and was less expensive than the TMS-DM method which is more convenient for an accurate and thorough analysis of richcis/transUFA samples.

Three methods of assessing relative abundance of wild canids were evaluated on a population of dingoes, Canis lupus dingo (Corbett), on a cattle station in south-westem Queensland. The tested indices relied on measurements of activity based on spoor. Two of the techniques attracted the target species to tracking stations through the use of a novel (fatty acid scent) or food-based (buried meat) attractant. The third index (activity) measured the number of dingo tracks crossing tracking stations placed at 1-km intervals along a road transect. All three indices had a high level of agreement for detecting differences in relative abundance, with correlation coefficients exceeding 0.85. When the stations were analysed in 1-km segments, the activity index proved the most sensitive, producing proportionally more positive responses than either of the other two indices irrespective of whether the tracking stations were assessed at 1-, 2-, 3- or 4-day intervals. Inconsistencies between indices existed, with the derived abundance indices not showing the anticipated reduction following population reduction. The effect of season and the interaction between dingo activity and index methodology are discussed.

Relevance of the study. The problem of thematic misbalance in news is indisputable nowadays. Newsmakers are obliged to meet not only standard news criteria, but also a media audience expectations regarding the structuring of its interests. The main objectives of the study were to detect the coherence in agendas of the leading Ukrainian TV channels as well as to trace their conformity with the public agenda. Methodology. Content-analysis method was used to identify those topics in news stories (N=1186) that got the most attention on the studied channels. Calculating the coherence and rank correlation coefficients made it possible to trace the commonality in thematic priorities among channels themselves and between channels and their audience. Data triangulation method made it possible to select the points of public agenda from the survey by the “Democratic Initiatives” Foundation. Results. The studied channels tend to reflect Ukrainian and world events in identical thematic proportions: coherence coefficient of devotion attention to the topics was fixed at a high level: W = 0.87 (p≤0.005). There is a tendency for emphasizing particular range of issues (bureaucrats, corruption, crime, material support) and missing from attention of some others (decentralization, environmental issues). Only a half of the topics (49%) was identified as important to the public’s view, other issues didn’t correspond to public agenda, therefore, the manifestation of the agenda-setting effect was fixed at a weak level (r = 0.2 at p> 0.1). The probable cause of the low correlation between media and public agendas may be the deterioration of living standards in Ukraine due to current state of war conflict. Conclusions. In terms of thematic priorities, leading television channels can be characterized by a high degree of consistency, while the television agenda is only half-compliant with public agenda, so that its conformity with the public agenda was fixed at a weak level.

Aims: Thyroid volume has to be measured in goiters prior to radioiodine treatment to calculate the needed amount of radioactivity. Modern clinical equipment for ultrasonography shows the trend to smaller probes, so that larger goiters do not fit any longer into the probe’s field of view. This study evaluated the feasibility and accuracy of stitching procedures applied to thyroid volumetric analysis performed using three-dimensional ultrasound (3D-US).Material and methods: Ad hoc thyroid phantoms of different shapes (regular, nodular, thickened isthmus) and volumes (ranging between 50 and 400 mL) were developed. In 15 such phantoms the left and right lobes were separately scanned, and the 3D-US datasets were then assembled (stitched) using predefined landmarks and dedicated software. Volumetric analysis was then assessed via a conventional ellipsoid model (em) and manual tracing (mt). The correlation of measured and reference volumes was determined using Pearson’s correlation coefficients and Bland and Altman limits of agreement.Results: The results showed a high level of agreement (with correlation coefficients ranging from 0.974 to 0.999) for all shapes and volumes tested, including the largest volume of 400 mL. The mt method, although more time consuming, proved superior to the em.Conclusions: Stitching-mediated thyroid volumetric analysis is accurate, and its clinical performance should be investigated in future studies

This study investigates the preferences of instructors and students for design and pedagogy features of online instruction at the post-secondary level. Participants included 60 instructors and 200 students at a comprehensive research university. Correlation coefficients of .95 on the design item rankings and .87 on the pedagogy item rankings were found between instructors and students. An independent sample T-test was conducted, resulting in a finding of significant difference between the preferences of instructors and students on 19 of 63 features. Additional findings included the high level of agreement on design and pedagogy features among all students as a group and subgroups (e.g., students earning regular university credit and those pursuing professional development goals.) An interesting finding was the concurrence in the low preferences by instructors and students. Both groups rated low those features pertaining to social networking and collaboration.

Background: There are several clinical techniques for the subjective measurement of heterophoria. In South Africa, von Graefe (VG) is a commonly used technique to quantify heterophoria using the phoropter.Purpose: The purpose of the study was to investigate the agreement of VG heterophoria measurement using the phoropter and a trial frame.Setting: The study was conducted at an Optometry Clinic, University of Limpopo, South Africa.Methods: Both distance and near horizontal and vertical heterophoria VG measurements were performed on 88 visually-normal university students using the phoropter and trial frame. The handheld rotary prism was used on the trial frame. The 95% limits of agreement in prism diopters were compared using the Bland-Altman statistical test.Results: For distance horizontal heterophoria, the VG means were 0.39 exophoria ± 2.0Δ and 0.38 exophoria ± 1.8Δ with the phoropter and trial frame respectively. The means for near horizontal heterophoria were 3.69 exophoria ± 3.3Δ and 4.13 exophoria ± 3.27Δ with the phoropter and trial frame. For the vertical heterophoria at distance, the means and standard deviations were 0.18 hyperphoria ± 0.74 and 0.13 hyperphoria ± 0.07Δ, while at near vision they were 0.03 hyperphoria ± 0.71 and 0.07 hyperphoria ± 0.71Δ, respectively.Conclusion: Measurement of VG heterophoria testing using the phoropter and trial frame showed a high level of agreement for both distance and near vision performed through the phoropter and a trial frame. For clinical and research purposes, the phoropter and trial frame can be used interchangeably for measuring heterophoria.

Abstract Transient-based methods in the frequency domain are used for fault detection in pipes. However, the required measurements are performed with a large number of valve frequencies. Sometimes the number of frequencies in traditional frequency-domain methods can be in the hundreds. More runs are required with higher harmonics when the required number of frequencies is more. The current study aims to overcome this difficulty of requirement of higher number of frequencies. The location and the size of a single leak or a single discrete blockage are proposed to be predicted using two appropriately chosen low frequencies. Iso-Pressure Frequency Responses (IPFRs) are generated by performing numerical experiments with these two low frequencies enabling determination of the fault. The methodology is demonstrated through various numerical examples. The results show that the procedure is quite accurate, with a high level of agreement between the actual and the predicted fault parameters. The error in the result is of the order of the chosen discretization. An uncertainty analysis is performed to illustrate that the prediction error caused by the error in the measurements of the pressure frequency responses (PFRs) depends on the location and the size of the fault itself. The error in prediction results is analyzed in uncertainty analysis with 0.10%, 0.15%, and 0.20% error in the peak head measurement. For the same error in the PFR measurement, the fault lying in a thin density of the contours would lead to a higher error in the final solution.

A kinetics enzyme-linked immunosorbent assay (ELISA) and a single-read ELISA for the detection of ovine anti- Toxoplasma gondii IgG were developed and optimized. During the kinetics assay, 3 optical densities were obtained for each serum sample at intervals of 45 seconds, and the results were presented as average slopes (replicates of 2) of the reaction rate between bound enzyme and substrate solution. The kinetics ELISA was stopped 5 minutes after dispensing the substrate to constitute the single-read ELISA, and the results were presented as average optical densities for duplicates of each sample. Performance of the assays was evaluated using the modified agglutination test (MAT) as the “gold standard.” There was a high level of agreement between both ELISAs and the MAT, as measured by Pearson correlation coefficients, kappa statistics, and the area under the receiver operating characteristics curves. The single-read ELISA was as accurate as the kinetics ELISA, with a sensitivity of 89% and a specificity of 96%.

Abstract Objectives Autoanalyzers are used in clinical haematology for analysis of blood samples in clinical as well as in nonclinical studies. The results from these analyzers vary from machine to machine. In this study, we compared the lymphocyte and neutrophil count of mouse blood between ADVIA 2120i, Horiba Yumizen H2500 and CellaVision analyzers against manual counting as gold standard. Methods Blood samples from 28 female BALB/c mice were collected and analyzed. Agreement between different autoanalyzers and manual counting were determined by Bland–Altman method. Results A high level of agreement was found between CellaVision and manual technique for lymphocyte (Bias=4.75, 95% limits of agreement −14 to 24) and neutrophil count (Bias=0.68 (−17 to 19)). Agreement in lymphocyte count was also observed between ADVIA and manual counting, but to a lesser extent compared to CellaVision (Bias=13.9 (−10.45 to 38.27)). However, no agreement was observed for ADVIA (Neutrophils), Horiba (lymphocytes and neutrophils) with manual counting. Conclusions Our data suggests that CellaVision could be used for the differential counting of neutrophil and lymphocytes in mouse blood sample.
