Abstract The paper is motivated by critical demand for experts and scientists working in areas of mathematical modeling, simulations, big data techniques and who are familiar with management of HPC systems from user and administrator point of view. We created a new course entitled “HPC system management”. Our goal is focused on students to provide them with knowledge and understanding of complex problem of the HPC system management concerning job scheduling. Important fact is that the job scheduling problem is an NP-complete problem. Next objective of our course is to educate skilled experts, who are able to design and implement programs, scripts and models doing job management to solve specific parts of this complex problem. The course is innovative from several points of view. Our new approach lies in specific content, which is oriented to the HPC system management in contrast to existing courses, which are usually focused on development of HPC applications. Also we developed and provide new education methodology in a form of scientific project, which decomposes the complex problem into subproblems and subsequently brings together solutions to the subproblems to form united model. New education methodology is focused on generation of (pseudo-) optimal jobs schedule using data from real systems. The huge volume of used data leads to ideas and methodologies of problem solving, which are suitable for problems not solvable in polynomial time. Educational methodology also contains implementation of a job scheduling simulator. The paper presents a pilot course, in which students explore various scheduling algorithms and research their properties with the use of data gained from NorduGrid

The scientific and methodological approach to the evaluation and analysis of the efficiency of system management by innovation factors for sustainable development of national economy from the point of view satisfaction vital interest’s population is developed. This is the calculation of the modernized index human development based on the adjective model based on 26 indicators (social, economic and environmental subsystems), as well as using the methods of the main components and the slip matrix. The resultant value is the modernized Human Development Index (MHDІ) of Ukraine. The architectonics MHDІ of Ukraine in 2007–2017 from the position of sub-indices of the ecological, social and economic subsystems is analyzed. Consequently, the scientific and methodological approach based on the MHDI change allows us to draw conclusions regarding the effectiveness of the work and public administration bodies in the context of making managerial decisions regarding the satisfaction of the vital interest’s population. MHDI considers the main regulated parameter of the system management in the innovation factors of sustainable development in socially oriented economy. The tendency of steady decline MHDI of Ukraine in 2007–2017 on 53.45 % was confirmed, which confirms inefficient state regulation of crisis situations in Ukraine. In order to increase the efficiency management of innovative factors by sustainable development of the national economy, from the standpoint of satisfaction vital interest’s population, it is proposed to intensify the use of public debt and savings bonds, market and non-market methods of relief and debt load. This is due to the fact that at the current stage of development in the national economy, public external debt is one of the most significant indicators of the state economy. It is at the same time a criterion for the effectiveness of public financial policy, as well as a threat and opportunity for the Ukrainian economy. In order to optimize its size, various methods, approaches, tools are used. Based on the analysis of world experience, it has been established that the securities market, in particular debt securities, plays a strategic role in regulating this issue. Therefore, it makes sense to recommend government debt bonds and government savings bonds to optimize the amount of external public debt.

Corruption is a key factor that affects countries’ development, with emerging countries being a geographical area in which it tends to generate greater negative effects. However, few empirical studies analyze corruption from the point of view of disclosure by companies in this relevant geographical area. Based on a regression analysis using data from the 96 large companies from 15 emerging countries included in the 2016 International Transparency Report, this paper seeks to understand what determinants affect such disclosure. In that context, this paper provides empirical evidence to understand the factors that influence reporting on anti-corruption mechanisms in an area of high economic importance that has been little studied to date, pointing to the positive effect of press freedom in a country where the company is located and with the industry being the unique control variable that strengthens this relationship.

Inflation is a key element of a national economy, and it is also a prominent and important issue influencing the whole economy in terms of marketing. This is a complex problem requiring a large investment of time and wisdom to attain positive results. Thus, appropriate tools for forecasting inflation variables are crucial significant for policy making. In this study, both clarified value calculation and use of a genetic algorithm to find the optimal parameters are adopted simultaneously to construct improved models: ARIMA, GM(1,1), Verhulst, DGM(1,1), and DGM(2,1) by using data of Vietnamese inflation output from January 2005 to November 2013. The MAPE, MSE, RMSE, and MAD are four criteria with which the various forecasting models results are compared. Moreover, to see whether differences exist, Friedman and Wilcoxon tests are applied. Both in-sample and out-of-sample forecast performance results show that the ARIMA model has highly accurate forecasting in Raw Materials Price (RMP) and Gold Price (GP), whereas, the calculated results of GM(1,1) and DGM(1,1) are suitable to forecast Consumer Price Index (CPI). Therefore, the ARIMA, GM(1,1), and DGM(1,1) can handle the forecast accuracy of the issue, and they are suitable in modeling and forecasting of inflation in the case of Vietnam.

While it is a truism that political voice is a cornerstone of democratic theory, less theorizing has focused on its counterpart, political listening. Drawing upon research related to listening practices, this study operationalizes for empirical study Dobson’s (2014) normative concepts of apophatic listening, which is dialogic and facilitates discussion across lines of difference, and cataphatic listening, which is monologic and disruptive in nature. Using data from a national sample survey of Latinos fielded shortly after the 2016 U.S. presidential election (N = 720), we provide an empirical test of these listening practices’ democratic value by examining how relational and analytical listening (dimensions of apophatic practices) and task-oriented and critical listening (dimensions of cataphatic practices) are associated with various political outcomes, including political interest, knowledge, trust, and participation. Findings indicate that, from a normative point of view, task-oriented listening was unrelated or negatively related to political outcomes while relational listening had ambivalent relations. However, the two cognitive-epistemic dimensions of both types of listening – analytical listening and critical (error-seeking) listening – were both strongly and positively related to most studied political outcomes. These findings offer nuanced evidence that apophatic and cataphatic listening might not necessarily be at odds with each other where democratically desirable outcomes are concerned.

Abstract Background and Purpose: This paper analyses the strategic aspects of knowledge management in organizations in Serbia, from the theoretical and empirical point of view. In its theoretical part, the paper analyzes the latest literature in the fields of knowledge management, relations between communications strategyes and knowledge management, generations of knowledge management and organizational culture. Design/Methodology/Approach: In its empirical part, the paper deals with determining the level of knowledge management in Serbian organizations through diffrent generations of knowledge management, as well as the problem with explicit and tacit knowledge management. The hypotheses were tested using data colleted from organizatons in Serbia via questionnaire, which consisted of 50 questions to examine five key factors in knowledge management. Results: The results showed that out of 41 indicators, only eight are rated positively. Results of t-test indicate significant distinctions within factors affecting the quality of knowledge management, as well as differences in quality of explicit and tacit knowledge management, therefore they confirmed both hypotheses. Conclusion: The knowledge management projects in organizations in Serbia are initiated, as well as that belonging to the first generation of knowledge management can be defined.

This article considers approaches to studying the career capital in the interdisciplinary career studies from the point of view of the creating conditions issues for professional development of employees. The concept was formed within the framework of the interdisciplinary career research, based on the concepts of the human, social and cultural capital, as one of the tools for understanding new processes in the field of labor. The content of those processes determines, among other things, the growing variety of career models and the need to adapt them to organizational strategies. Attention is focused on studying those concepts in two principal directions: considering it as a tool for management practices in modern organizations and considering it in the perspective of the career theory development. Conclusions are drawn that approaches to considering career capital are based on interdisciplinary interaction and understanding of the multilevel context of a career in the organizations research. Groups of environmental infrastructure factors are identified for the development of professional promotion opportunities; professional training of employees; individual career success.
