This article presents approaches to estimate orderliness of transport service of large city by means of city passenger public transport (CPPT). An article considers entropic analysis method as main analytical instrument of orderliness of transportation process. Author presents cause-and-effect chain of formation of results of transportation process by CPPT and process of informational transformation during transportation. An article gives an example of calculation of relative entropy of transportation process by CPPT in Tyumen during March-September 2020. Additional attention was paid to changes of orderliness of transport service during the acute phase of pandemic COVID-19 (April-June 2020). It was established that relative entropy of transportation process decreased during acute phase of pandemic COVID-19 in comparison to periods of sustainable functioning of CPPT system. Respectively orderliness of transportation process increased at the same time. This fact can be explained by structural changes of volume of transported passengers (total volume of traffic – volume of transportation of preferential passengers – volume of transportation of senior citizens). By the results of research author made conclusions and gave recommendations on possible increasing of orderliness of CPPT transportation process.

Abstract Background Coronary artery aneurysm (CAA) is an important complication of Kawasaki disease (KD) that is associated with arterial structure damage. However, few studies have examined structural changes in coronary arteries that are not associated with CAA. Methods We examined coronary arteries in KD patients with CAAs who underwent follow-up coronary angiography (CAG) and optical coherence tomography (OCT). Coronary arterial branches with no abnormal findings during the most recent CAG were classified into two groups. Arteries with an acute-phase CAA that later regressed were classified as group R; arteries with no abnormal findings on either acute or convalescent phase CAG were classified as group N. Coronary arterial wall structural changes were compared between groups using OCT. Results Fifty-seven coronary arterial branches in 23 patients were evaluated by OCT. Thirty-six branches showed no abnormality during the most recent CAG. Both groups R and N comprised 18 branches. Maximum intimal thicknesses in groups R and N were 475 and 355 µm, respectively (p = 0.007). The incidences of media disruption were 100% and 67%, respectively (p = 0.02). Calcification, macrophage accumulation, and thrombus were not found in either group. Conclusions Intimal thickening and disruption of the media occur in coronary arteries with acute phase CAAs that later regress in the convalescent phase, as well as in arteries with normal CAG findings in the acute and convalescent phases.

The paper presents the possibility, necessity, ideology and essence of the entropy method of estimating the orderliness of the transportation process in relation to urban public transport. Examples of numerical definition of the relative entropy of the transportation process on typical public transport routes are given. The paper shows that the level of orderliness of the transportation process, identified by relative entropy, is determined by the specifics of the spatial location of public transport routes in terms of the urban area and mainly depends on the quality of users of public transport services.

This work contains a description of a technique for constructing two synthetic indicators (measures) using a graphical presentation in the form of radar maps. The paper presents the structure and properties of indicators and their formal notation specially created for this purpose using the analogon of a scalar product of vectors. In particular, it proves the theorem on polygon fields, induced by radar maps, prepared for structural vectors, which allows to build concentration indicators. In order to demonstrate the usefulness of tools constructed by such means, the example shows how significant structural changes can be imperceptible when utilizing only the GINI concentration indicator’s value, but are noticeable when using the concentration indicator developed by the authors. In addition, it illustrates the change in the value of concentration indicators (GINI and the indicator developed by the authors) on two families of Lorenz curves, together with changes in concentration. The practical application of this technique for constructing indicators that create rankings is presented on empirical data on the level of material deprivation in the countries that joined the EU in 2004 and 2007. These data have also been annotated (for comparison purposes) using the so-called overrepresentation maps (Grade Correspondence Analysis method).

The ranking of decision-making units (DMUs) is one of the most significant issues in efficiency evaluation. However, the calculation results from the traditional DEA method sometimes include multiple efficient DMUs or multiple DMUs with the same efficiency value, in which case the approach is weak in distinguishing among these DMUs. Therefore, this study proposes a DEA cross-efficiency ranking method based on the relative entropy evaluation method and the grey relational analysis method. First, the approach uses the cross-efficiency matrix as the decision matrix of multiple criteria decision-making (MCDM), and the relationship between DMU and the ideal solution is analyzed by the grey relational analysis method and the relative entropy evaluation method. Then, the degree of the criteria is determined by Shannon entropy, and the weighted grey correlation degree and the weighted relative entropy are obtained. Finally, with the comprehensive relative closeness degree between the DMU and the ideal solution, we can sort all the DMUs accordingly. In a comparative analysis, it shows that this method analyzes the similarity between DMUs and the ideal solution from the information distance and the similarity of the data sequence curve, and has certain advantages for analyzing the ranking of DMUs.

Abstract Quantitative microfluorimetric measurements on individual acridine orange (AO) stained cells showed that leukocytes from patients with infectious mononucleosis (IM) exhibited considerably greater AO binding to deoxyribonucleoprotein (DNP) than leukocytes from healthy persons. The higher binding of AO could not be explained by an increase in the amount of DNP in IM cells but by an increased number of binding sites in DNP accessible to AO. This was the result of structural changes in the DNP complex of the IM cells, possibly due to weakened bonds between the DNA and protein moieties of DNP. The binding of AO to IM leukocytes was highest in the early phase of the disease and usually normalized after recovery. However, an increased AO binding of leukocytes from patients after recovery was frequently observed when these cells were exposed to plasma from patients in the acute phase of IM.

AbstractThis article analyzes critical voices raised against the Bologna Process by various stake-holders of higher education in Turkey, such as rectors, professors, international office staff, students, and civil society organizations. The data collected through in-depth interviews were analyzed using the discourse analysis method on the basis of the interlocutors’ reflections on the Bologna Process. It is claimed in the article that most universities in Turkey have attempted a process of internationalization and institutionalization, but that there have been several impediments during the implementation of the Bologna Process. Rising Euroskepticism in Turkey has also changed the process of Europeanization in the universities. It is revealed that the structural changes made in line with the Bologna Process are perceived by several different stake-holders as neo-liberal acts, and are presented as activities of internationalization, but not of Europeanization.
