Entropy and information in scenario modeling of a firm: new approaches in business economics

This article aims to measure the level of voluntary disclosure in the published annual reports of Yemeni Islamic banks. Four full-fledged Islamic banks from Yemen are selected for the current study. A disclosure checklist covering 266 items is prepared and a 10-year period, 2005–2014, is taken. The disclosure index items were classified into seven groups, such as basic information on Islamic banks, financial ratios, corporate governance information, financial statements data, corporate social disclosure, Zakat information, and other information that has been taken as an important attribute of voluntary disclosure. The obtained results show that the amount of voluntary disclosure that Yemeni Islamic banking institutions publish in their annual reports has gradually increased over the ten years examined. The results revealed that the highest average disclosure index score over the ten years was achieved by Tadhamon Islamic International Bank (TIIB), the second highest average disclosure score was obtained by Saba Islamic Bank (SIB), and the lowest average voluntary disclosure rating score during the ten years surveyed was achieved by Shamil Bank of Yemen & Bahrain in Yemen during the study period. Substantially, the result of voluntary disclosure scores indicates that the degree of voluntary disclosure by Yemeni Islamic financial institutions has relatively expanded during the ten years investigated. The findings provide new evidence for voluntary disclosure, particularly, Islamic disclosure items. The survey findings can be useful for regulators in Yemen to improve overall disclosure practices by Islamic banks operating in Yemen.

The study’s relevance relates to the transformation of the human capital reproduction during the transition to a new socio-economic model and changes (digitalization, cyberization, customization, etc.) that are now taking place within Industries 4.0 and 5.0. The purpose of the study is to formulate the content and key directions of learning processes based on modeling and the formation of digital twins for the production and consumption of goods. The research method is based on the analysis of structural links in socio-economic systems, where the potential of human capital is realized. The study describes a trialectic model for the system development mechanism, which gives grounds to distinguish three types of essential components of implementing the specialists’ competencies (material, information, and communication). Based on the concept of “system of systems”, the necessity of multifunctional training of specialists for socio-economic systems is substantiated and shown on the list of personal knowledge/skills in the renewable energy sector. Recent trends in the reproduction of human capital, such as intellectualization, increased communication, internationalization, acquisition of skills, customization, and communication with consumers, are stated in line with Industries 4.0 and 5.0. The potential for future research is aimed at harmonizing relations between humans and cyber-physical systems, motivating the needs for self-development, and using disruptive technologies in the reproduction of human capital.

This study aimed to explore the attitudes of students of a higher education institution towards infopreneurship. The study emanated from observations that the widespread use of information technologies has created a new sector in the labor market – infopreneurship. The study adopted the case study research design based on focus group discussions to establish the students’ attitudes towards infopreneurship. The participants for the focus groups were students of the Information Science department at the University of Technology, Cape Town. Data collection during the focus group discussions was based on unstructured interviews. Quantitative data analysis was applied based on data reduction from codes to categories. An enterprising attitude (26.4% code frequency) dominated the positive responses while negative attitudes were mainly reflected by a critical attitude (20.8% code frequency) towards infopreneurship. While it appeared that positive attitudes were more prevalent than negative attitudes, there were notable observations that the respondents were critical or neutral towards the essence of infopreneurship in the South African context. It was found that the belief that infopreneurship is not a viable form of employment was still prevalent. Some respondents believed that employment means working for someone. They felt that there is greater respect in being employed than engaging in infopreneurship. Some respondents, however, appear to have stronger entrepreneurial orientations and felt that infopreneurship offers the best employment opportunities. The study recommends changes in higher education curricula and the creation of a stimulating environment for infopreneurship.
