Studying contemporary and subfossil Cladocera (Crustacea) communities, we explored the effect of top-down stressors on the cladoceran communities; we are also interested in the coherence of the contemporary and subfossil communities. The studied Cibakháza oxbow lake is in E Hungary, on the left-floodplain of the River Tisza; it is a large, long, and shallow oxbow lake. Three areas of the oxbow lake were distinguished based on the strength of top-down stress: protected area with low top-down stress, biomanipulated area with high top-down stress, and recreational area with moderate top-down stress. Altogether, we identified 28 taxa in the contemporary and subfossil communities in the oxbow lake. We found that the species number of the contemporary Cladocera communities was lower (protected area: 13; biomanipulated area: 9, and recreational area: 14) than in the subfossil communities (protected area: 20; biomanipulated area: 16, and recreational area: 14). Among the environmental variables, we observed differences between the protected and biomanipulated area, while the recreational area showed a transition. Species number, abundances, and Simpson diversity also showed the effect of the fish introduction. There were no differences in beta-diversity among the contemporary and subfossil Cladocera community. The non-metric multidimensional scaling (NMDS) ordination showed that the biomanipulated area in the case of the contemporary communities was separated from the other areas, while in the case of the subfossil communities, there was no separation according to top-down stress. Our results showed that the number of species of contemporary Cladocera communities was lower in each area (3–10; 3–9; 5–9) compared to the subfossil communities (6–17; 7–12; 8–12). However, the highest abundances were found in the biomanipulated area due to the appearance of small-sized Cladocera species. Our findings suggest that the effect of a short-time fish introduction is restorable when the oxbow lake has a protected part.

Purpose
The purpose of this paper is to present the experience, successful management and the succession of generations in a Hungarian corporation in the food industry through the “Best Practice” model.
Design/methodology/approach
The chosen methodology for this paper is “The best practice model” prepared by The Solutionist Group. The model presents the characteristics of family businesses and illustrates how the process of sustainable enterprise differs in different fields concerning family and non-family businesses. In applying this model, the experience, successful management and the succession of generations will be presented in the case of a large Hungarian enterprise which has a determining role in the Hungarian food industry. The results are based on the question framework of the expert interviews.
Findings
The history of family-owned firms shows that in order to maintain appropriate business succession activity the family management has to plan in advance. Passing the baton to the next generation successfully is a complex and long-term family management role and it has strategic importance. To ensure business continuity, the successor has to take over the business and operate it well. That is why the sharing of knowledge, the innovation performance and the best practice are important parts of family company’s culture, and they consequently play an important part in the pass the baton project within family-owned firms.
Originality/value
This paper expands the knowledge about the succession of family businesses.
The aim of our article is to show the importance of the agriculture in the global life. One of the most important challenges of the world to produce enough food for the growing population of the Earth. The food production needs to be increased not only because of the growth in population but also because of the changing dietary habits. While the agriculture tries to produce more food they have to solve several problems. Increasing need for water, soil degradation and climate changethese are only a few of the most important problems we are facing right now. We have to increase the agricultural production on less arable landbut the question is: how? The role of education and especially the agricultural education became much more important in this case. Prior researches showed that for the improvement in the skills and knowledge of the farmers and agricultural employees we have to analyse the actual situation and challenges of the agricultural education. To serve the needs of the precision agriculture, the educational system have to pay attention for the changing needs of the agricultural system. During the reform of higher education and the agricultural higher education the most actual developments have to be included in the curricula. The labour market wants the higher education to offer actual knowledge for the students and for professionals as well during formal, informal and non-formal education as well. As the technology used by agriculture is continuously developing the employees and the farmers need different courses as parts of the lifelong learning systems.
There are concerns about the impact of Industrial Revolution 4.0 and challenges on the job market. This research purpose is to analyze the impact of the 4.0 industrial revolution on the labor market related to its consequences for higher education. Based on the Systematic Literature Review using VOSview, this research found the challenges of Industry 4.0 on the job market in Indonesia. Based on the challenges, this research purpose competencies and skill acquired and how the need for higher education to change to answer these challenges.
The rapid proliferation of the demand-side, platform-based collaborative economy and its various forms have been an aspect of everyday life for over a decade. However, despite the platform’s popularity, the descriptions and names attributed to the demand-side, platform-based collaborative economy are often used interchangeably and can be ambiguous, resulting in confusion among researchers and practitioners. This study examines the articles published during the previous ten years, which have aimed not only to define, but also to classify, the collaborative economy according to various criteria. After reviewing the existing classification criteria, this article presents a clearer taxonomy of the multiple forms of the collaborative economy by distinguishing service providers’ groups on their respective attributes. Our review and analysis have both theoretical and practical importance. Regarding the latter, our research will help managers and government officials alike in rethinking the taxation and subsidizing policies related to the various demand-side, platform-based collaborative economies and in preparing national and international consultations and conventions. This study aims to define the demand-side, platform-based collaborative economy and integrate the concept into various economic activities, providing a new and valuable contribution to the literature.
