Corporate Governance and the Practice of Business Ethics in Slovenia

This article contributes both quantitatively and qualitatively to the discussion on implementation of business ethics, as a basic background of social responsibility leading to systemic behaviour. In the frame of business ethics the ethical core values, culture, ethical climate, informal, and formal measures of business ethics implementation is addressed. The article is also aimed to improve understanding of importance of (ethical) corporate governance, key stakeholders’ influence on the enterprise’s core values, culture, the ethical climate, and informal and formal measures of business ethics implementation as the constitutional elements of enterprise ethical behaviour. The article briefs important cognitions of various empirical researches on business ethics in the case of Slovenian enterprises. The business ethics strongly relates to, and matters in, achieving more enterprises’ social responsibility and humankind’s well-being.

Mechanism Construction of Human Resource Management based on Blockchain Technology

The traditional human resource management system is faced with such problems as the quality of staff recruitment can not be guaranteed, the training performance is not consistent with the actual performance, the enterprise performance appraisal is unfair, and the salary distribution is unfair, which seriously affects the enthusiasm and loyalty of employees and threatens the survival and development of enterprises. In view of the current situation and problems of human resource management system, combined with the technical characteristics of blockchain, this paper proposes a human resource management mechanism based on blockchain technology, in order to achieve the company's human resource management system accurate, efficient, open and transparent. It is found that there is a good coupling between blockchain technology and human resource management system. This paper constructs a human resource management mechanism based on blockchain, innovates the application scenarios of blockchain technology, and provides certain guiding significance for the establishment of human resource management system and process improvement in the future.

Management Sciences/Operational Research Units in Business and Management Courses in the UK

The paper reviews the development of management science/operational Research (MS/OR) in management education and explore how far the syllabuses of undergraduate business courses and MBA courses in the UK, are giving space to the teaching of management sciences methodologies (MSM). The academic phase of early MS/OR is outlined and a time-based framework to map the evolution of four MS/OR discourses informing a set of MSMs currently in use is advanced. At an undergraduate level the review is based on a sample taken from Universities and Colleges Admissions Services (UCAS) of business and management studies degrees and at a postgraduate level the review considers a sample of MBA programmes offered by six UK universities. Results indicate that most of the MBA courses include a core unit in quantitative methods in the first year and that universities are still at large teaching the ??hard?? end of the MSM spectrum, the type of problem solving methods developed in the 1950s and 1960s. Business courses incorporating units containing systemic thinking and management sciences methodologies developed from the 1970s to now (e.g.: soft systems methodology, viable systems model, cognitive mapping), are rarely taught at undergraduate (UG) level; and at post-graduate (PG) level they have been confined to a handful of institutions in the UK. The paper highlights the fact that MSMs associated with the soft and critical end of the spectrum are still lacking of credibility amongst the designers of management education at both undergraduate and graduate management education. Conclusions from the survey results are drawn and an agenda for further research is proposed.

Primary Analysis of Development Approach to Chinese Satellite Mobile Communication

The paper describes the development of mobile communication first and then points out that it is necessary for China to develop satellite mobile communication after comparing the cellular mobile communication with the satellite mobile communication. After comparing the geostationary satellite system with the low earth orbit satellite mobile communication system, as well as the single beam with the multi-beams, both used in satellite mobile communication, we suggest that China, according to its economic status and level of satellite technology, should develop a geostationary multi-beams satellite for its domestic mobile communication.
