Crop diversity has an important role in sustainable agroecosystems. This study analyzed the crop diversity of agricultural holdings in particular regions (NUTS III) in Slovakia and identified the impact of Common Agricultural Policy (CAP) payments on the crop diversity of agricultural holdings. There are regional disparities in crop diversity in Slovakia. The highest crop diversity is typical for the regions with the best soil quality. From the results of econometric models, it was found that some of the CAP payments have an effect on crop diversity, mainly single area payment scheme (SAPS) payments, which had a negative effect, and payments for areas facing natural constraints (ANC) and animal welfare, which were found to have positive effects. It can be concluded that the second pillar of the CAP is able to improve or at least maintain crop diversity in Slovakia. Other important factors found to influence crop diversity are irrigation, total crop area corresponding with the farm size, geographical location including the soil quality, and the legal structure of agricultural holdings. However, the distance of the farm from the city, the education of managers, and membership in farmers’ associations are not important factors for crop diversity in Slovakia.

Agricultural land is a limited natural resource with increasing economic value. This study analyses land rental relationships in Slovakia, including legal rental regulations, and identifies the impact of certain factors, such as the European Union Common Agricultural Policy (CAP) payments, and geographical and economic factors on land rental prices. From the results of econometric models, it was found that certain CAP payments have an effect on rental prices, mainly the single area payment scheme (SAPS), payments for agri-environmental-climate schemes (AECS), and animal welfare, which were found to have positive effects. Other important factors found to influence rental prices are economic indicators (such as total revenue share of total costs, share of revenue from agricultural production in terms of total revenue, share of production costs as a percentage of total costs, wages, and number of employees) and geographical factors (such as region or partial production areas). However, the distance of the farm from the district city (LAU 1) and the share of farmland affected by natural constraints do not considerably affect rental prices in Slovakia. Land consolidation is a statistically significant factor according to the models; however, its impact is almost zero. Knowledge of these factors constitutes important know-how, not only for policy makers but also for the actors operating in the land rental market (e.g., landlords, tenants, experts on land valuation, and real estate agents).

The most important purposes of Slovakian universities are research and education. The main goal of university education is to prepare highly skilled graduates to be employed in the labour market either at home or abroad. To achieve this goal, universities need to receive feedback from their graduates as to whether they are satisfied with their education and whether their employers are satisfied with their skills. The results obtained in this study show that, except for graduates from technical sciences, most graduates of Slovakian universities are not satisfied with the study programmes they chose. There are various factors affecting the satisfaction of graduates with their study programme; however, the most important ones were related to their employability and their employment in their field of study. Moreover, potential employers have greater expectations in relation to soft skills than graduates have acquired. The greatest differences between the required and acquired skills were seen in soft skills, such as the ability to take responsibility, to communicate with people, to negotiate, and to adapt to change, regardless of the field of study. Other than foreign language skills, the level of required hard skills was only slightly higher than the level acquired. According to these results, we make recommendations for universities, politicians, and potential employers; however, only reasonable cooperation among them can lead to graduates being satisfied with their chosen study programme.

The key element of the European Union (EU) Common Agricultural Policy is sustainable agriculture where the social, economic, and environmental objectives should be fulfilled. This role can fulfill only those agricultural holdings that are effective in the transformation of inputs to outputs, and which do not waste the inputs. Therefore, we analyze the technical efficiency of the agricultural holdings in the Slovak regions, and try to identify the factors that are able to influence the efficiency of agricultural holdings. We can conclude that there are regional disparities in technical efficiency in Slovakia; however, the problem of inefficiency is not typical only for the agricultural holdings in the areas with natural constraints. These regional disparities should be considered when adopting a new political measure to support sustainable agriculture. By the results of econometric models, we find that the agricultural production diversity, the policy of the labor market, and tax policy are the important factors influencing the technical efficiency of the agricultural holdings in Slovakia.

Plagiarism is a serious problem in the academic environment that affects academic honesty. However, there is usually a lack of knowledge regarding what kinds of practices can be regarded as plagiarism, as it is defined according to various ethical rules that differ from country to country. There is no commonly accepted definition encompassing all currently recognized forms of plagiarism. Therefore, some authors consider pedagogy to be the best measure against plagiarism. To research the impact of educating students on how to correctly quote sources on rates of plagiarism and the impact of specific factors causing plagiarism, we analyzed the measures of association among nominal variables from a dataset based on a survey of bachelor’s and master’s degree students in Slovak universities. According to our results from the Slovak universities, we can confirm that education has a positive impact on the elimination of plagiarism; however, teaching itself is not a sufficient measure to fight plagiarism. Other measures, e.g., checking seminar papers for plagiarism or making regular changes in topics for assignments, must accompany the educational measures that make an effort to eliminate plagiarism. The prevention of certain types of misconduct involves a long process; the teachers must implement educational measures and then uncompromisingly demand that students respect those measures.

The agricultural land market and its legal and political limitations play an important role in sustainable agricultural production. This study analyzed the agricultural land market in particular regions of Slovakia in terms of the sustainability of agricultural production. We focused on the development of proposed land prices between 2014 and 2018 to find out whether the prices proposed by landowners align with administrative land prices reflecting the soil quality in particular regions of Slovakia, or whether they are influenced by the proposed land prices of neighboring regions. Moreover, we focused on the existence of regional differences in proposed land prices in Slovakia, including differences in supply prices of arable land and permanent grasslands in particular regions. Statistical induction tools, together with multiple range tests and spatial autocorrelation, were used to confirm or refuse our expectations. We confirmed statistically significant differences in proposed land prices between regions. Moreover, we found that landowners are only influenced by the proposed land prices of their neighboring regions to a slight degree. However, we found that the price scissors between proposed land prices and administrative land prices open towards smaller administrative land prices, meaning that land of poorer fertility is supplied at a higher price than land of the best soil quality. There is a risk that expensive and poorer land plots will be used by investors for non-agricultural purposes, and agricultural production will be crowded out from these regions. Therefore, we propose that changes to the prepared legislative measures are necessary in order to promote the sustainability of agricultural production in all regions of the country.
