IDIMT-2024 : Changes to ICT, Management, and Business Processes through AI : 32nd Interdisciplinary Information Management Talks Sept. 4–6, 2024 Hradec Králové, Czech Republic / von Doucek, Petr / digitalization and economic freedom
No full textIn the minds of the average European citizen, and especially young citizens, the digitisation of government, business and everyday life- that is, of society as a whole- is linked to the growth of convenience, comfort and well-being. But is this really the case? In our paper, we compare the growth in the pace of digitalisation, as expressed by the DESI (Digital Economy and Society Index) (or its individual components) with changes in the EFI (Economic Freedom Index)(or its individual components). Our research for selected Central European countries is based on data for the period 2017-2022. The data source for the DESI index is the European Union database, and for the EFI is The Heritage Foundation database. Among the methods, we mainly used correlation analysis (Spearman's correlation coefficient) and data analysis using MS Excel tools and functions. Overall, the measurements show that the countries of the Middle East can be divided into three categories. The first category is countries where there is a strong correlation between DESI and EFI results. These countries are Austria, Slovak Republic and Slovenia. The second category is countries with a medium correlation- Poland, Czech Republic and Germany. The lowest correlation between DESI and EFI is identified in Hungary. More detailed causal analyses are presented in section 3.2 of the paper

IDIMT-2024 : Changes to ICT, Management, and Business Processes through AI : 32nd Interdisciplinary Information Management Talks Sept. 4–6, 2024 Hradec Králové, Czech Republic / von Doucek, Petr / Redefining threats : extending the threat response focus from external to internal threats
No full textThe objective of the contribution is to analyze the growing danger of insider threats and their impact on the security of company information systems and to show the select ways of their potential solutions in the Czech Republic and the Slovak Republic. Three basic approaches and thus also data sources were used for this article. The first source includes global quantitative data from large corporations identified for the time period of 2016-2022. The second source includes conclusions from a range of commercial and scientific projects in which the authors have been involved. The third source includes professional literature and documents concerning information security in organizations. The percentage and significance of insider incidents in current corporate practice, especially in large organizations, keeps increasing, as does the motivation to investigate these incidents, as the presented trends from the investigated time period. Also, the time to detect and resolve an insider incident is relatively long. Organizations can use the tools to protect themselves against insider incidents. Two limitations are crucial for the article. The data and conclusions are valid for large corporations. Their applicability to SMEs and micro-firms is not great. The analyzed input data are not a representative sample of the individual analyzed regions’ economies
Centralization of treasury management 2010
Get PDFThe book consists of five parts: 1. Treasury management and its responsibilities (Chapter 1‐4); 2. Decentralized treasury (Chapter 5); 3. Different phases of the centralization (Chapter 6‐9); 4. Outsourcing (Chapter 10) 5. Regional treasury centres (Chapter 11); 6. Best practices in a bank (Chapter 12); In the first part, the author describes the treasury management focusing on its three core responsibilities, such as assets and liabilities management, cash management, and financial risk management. The second part zooms in on decentralized treasury and decisions about the appropriate degree of centralization/decentralization of the treasury activities. Then we focus on the different phases of the process of centralization, from central interest rate and foreign exchange management through centralization of cash and liquidity management, then transaction processing up to fully centralized treasury. In part four we continue by discussing outsourcing as the next stage following centralization to achieve additional economic benefits. The fifth part contains especially a number of the location criteria, both tax and non‐tax, that must be evaluated during consideration where to establish the regional treasury centre. The last part deals with banking best practices in cash pooling from the point of view of the author that works in one of the top banks in Central and Eastern Europe region
The Penetration of ICT into the Economy—Technical Infrastructure in the V4 Countries
No full textPart 2: Data Management and Applications for EISInternational audienceThis article deals with the integration of information technology tools and services into the economies of European countries and compares the degrees to which ICT has penetrated into their economies and societies. Our evaluation of the penetration of ICT into economies within this article works primarily from the standpoint of infrastructure-services penetration. These services are today typically expressed through computer-network connection speeds. For our comparison of the nations of Europe, and of the V4 nations, we utilized public, open data for 2010–2014 provided by various institutions. These include primarily Eurostat, the Office of the European Union, the World Bank, and the Czech Statistical Office. In terms of methodology, the multi-criteria TOPSIS analysis method is used for comparison. A comparison of the penetration of technological infrastructure into the V4 countries between 2010 and 2014 and a comparison of them with the EU average is provided at the end of the article

The sample consisted of university students. Age, gender, and type of student job were used as control variables. With regards to the results, gender, openness to (cognitive) experience, and type of student job influence the adoption. It is male, more open to experience, and working student who use shared online calendars more
IDIMT-2023 : New Challenges for ICT and Management : 31st Interdisciplinary Information Management Talks Sept. 6–8, 2023 Hradec Králové, Czech Republic / von Doucek, Petr / Digital Services and Public Administration
No full textOne of the imperatives of the times is to vigorously reduce the costs of all business activities. This is no different in the state and public sector. One way is to digitise their agendas and digital communication between the state and the citizen. In this article we present the situation and development of digitalization in the Czech Republic. Firstly, its ranking among the EU countries, then we look at data mailbox services and the possibility of accessing e-government services in general. We measure the level of digitalization and state maturity within the EU using the DESI index - in 2022, the Czech Republic was ranked the 19th worst among EU member states. The use of data mailboxes is growing significantly in the Czech Republic, and users, however, focus mainly on downloading documents prepared for them by the state and public administration

Petr Harmach Department: Katedra anorganické chemie Supervisor: prof. RNDr. Petr Štěpnička, Ph.D., DSc. Abstract: The objective of this thesis was the synthesis of cyclometalated complexes of phenylpyridine with a ferrocenyl group. Cyclometalated complexes have a wide range of application, where one of the most important is the use in catalysis. Iridium(III) and rhodium(III) cyclometalated complexes were prepared containing electron-donating or electron-accepting groups on the pyridine ring. All newly prepared complexes were characterized by 1 H a 13 C{1 H} NMR spectroscopy, mass spectrometry, elemetal analysis and cyclic voltammetry. The structures of two complexes were determined by single-crystal X-ray diffraction analysis.
