Increasing the need for education for sustainable development in universities requires an understanding of the predictors of students’ environmental concern (EC). In this paper, the authors focus on the EC of business students because of their future responsibility for business operations regarding the exploitation of natural resources. The aim of the study is to examine the predictors of business students’ environmental concern.

Based on the Norm Activation Model as the theoretical framework, this study hypothesizes the model of EC with two main predictors: ascription of responsibility for the environment (AOR), driven by locus of control and self-efficacy (LC/SE), and awareness of positive consequences of consumption reduction on the environment (AOC), driven by perceived environmental knowledge. Structural equation modelling was applied to confirm the conceptual model based on the responses of business students from six countries (Czech Republic, Croatia, Hungary, Poland, Slovakia and Spain) collected through an online survey.

The environmental concern of business students is predicted both by the ascription of responsibility and by awareness of consequences; however, the ascription of responsibility is a stronger predictor of EC. A strong impact was found for internal locus of control and self-efficacy on AOR, as well as a weaker influence of perceived environmental knowledge on AOC.

Sustainability education dedicated to business students should provide environmental knowledge and strengthen their internal locus of control and self-efficacy in an environmental context.

The purpose of this paper is to overview the systems and their elements developing for supporting the less-skilled pi-lots.

Several European (like EPATS, SAT-Rdmp, Pplane, Esposa, Clean Sky2) and national projects (NASA SATS, Hungarian SafeFly) develop the personal/small aircraft and personal/small aircraft transportation systems. The projects had analysed the safety aspects, too, and they underlined the aircraft will be controlled by so-called less-skilled pilots (owners, renters), having less experiences. The paper defines the cross-connected controls, introduces the methods of subjective analysis in pilot decision processes, improves the pilot workload model, defines the possible workload management and describes the developing pilot decision support system.

Analysing the personal/small aircraft safety aspects, a unique and important safety problem induced by less-skilled pilots has been identified. The considerable simplification of the air-craft control system, supporting the pilot subjective decisions and introducing the pilot work-load management, may eliminate this problem.

Only the system elements have been used in concept validation tests.

The developing pilot supporting system in its general form has on - board and ground sub-systems, too, except a series of elements integrated into the pilot cockpit environment and control system. Several system elements (sensors, integrated controls, etc.) might be implement now, but the total system need further studies. The subjective decision process needs further development of the methodology and concept validation.

The system may catalyse the society acceptance of the personal aircraft and their safer piloting, applicability.

The paper introduces an original supporting system for less-skilled pilots.

This paper aims to the evaluation and comparison of the efficiency of winemaking in two developing countries (Ukraine and Bosnia and Herzegovina (B&H)) from the perspective of their development.

In this research study, four models of data envelopment analysis (DEA), correlation and other tools of the data analysis are used to analyze the efficiency of wineries in two developing countries. Returns to scale, scale efficiency, super-efficiency and some other indicators are examined. The research is based on the sample, including 33 wineries of Ukraine and B&H.

Characterized by the same average efficiency and number of leaders, in Ukraine, medium and large wineries are developing more efficiently than small ones, whereas the opposite is true for B&H. The authors found the high potential growth of efficiency on Ukrainian (up to 28.9 per cent) and Bosnian wineries (up to 28.3 per cent). The ways for its realization were suggested. Cross-country efficiency analysis enabled us to find inter-country leaders of wine industry. The authors grouped inefficient wineries, calculated the potential for inputs reduction and found the main directions for the improvement of efficiency for each group.

The research is limited to a single industry in only two developing countries. Future studies can be devoted to the comparison of the efficiency of wineries in developed and developing countries. The results can determine which countries can be leaders in the global wine market in the future.

This study provides useful information for: researchers of wine market in developing countries enabling them to understand the current state, basic problems and efficiency levels of wineries in Ukraine and B&H; domestic policy-makers- to improve regulation of wine industry as to make it more competitive and efficient; wine producers in these countries- to find the benchmarks using the best practices to adapt them in own business and to increase an efficiency.

On the example of Ukraine and B&H, this study has shown that each respective country has its own conditions of doing wine business. This is the first paper that compares the efficiency of wine industry in Ukraine and B&H.
