The main objective of this paper is to assess the reliability of selected measures of success/performance of small enterprises taking into account all the advantages and disadvantages of objective (traditional, financial) and subjective (personal perception) indicators. The realization of the basic objective will enable removal of doubt in different categories of success / performance of small businesses, which would be a secondary objective of the paper. The research methodology involves the use parametric procedures due to the characteristics of the selected variables and the number of observations in the sample. Univariate ANOVA and Pearson's coefficient correlation will be the main methods used. The basis of this study consists of data gathered from e-survey of 260 entrepreneurs/ owners/ managers of small enterprises in administrative sub-region of the Republic of Serbia. The analysis results show the correlation between subjective estimate of success of owners/ entrepreneurs/ managers and objective performance indicators, which can be characterized as complementary, meaning that subjective assessment as well as formally stated performance indicators are realistic. In addition, it is important to emphasize as an important result within the group of objective performance indicators, the differences between two groups, financial and non-financial, performance indicators.

This study aims to increase the knowledge on relations between corporate social responsibility (CSR), employee commitment, and firm performance in Serbia. The theoretical part of the article analyzes the relations between CSR and firm performances, as well as CSR and employee commitment, based on available world-wide research results. The empirical part of the article presents the research results for large companies in Serbia, regarding the relations between CSR and firm performance, CSR and employee commitment, and the mediating role of employee commitment on the relationship between CSR and firm performances. The sample consists of 53 large companies, each with more than 250 employees. The database was compiled between October 2019 and March 2020 using self-developed questionnaires. PLS-SEM analysis was implemented to uncover the relationship that exists between the variables. The authors determined that there was no direct effect of CSR on firm performances, but positive, statistically significant effects on employee commitment. Although the direct effect is missing, employee commitment has a positive mediation effect on CSR-firm performance link. The concluding part of the article outlines the theoretical and practical implications, acknowledges research limitations, and offers future research directions.

In addition to a family burden for BEN, other risk factors for CKD were highly prevalent in BEN villages of the Bijeljina municipality. The frequency of proteinuria was higher in the at-risk group than in the group without risk factors and increased with the number of risk factors.

GEM approach in measuring the volume of entrepreneurial activities and their interrelations with the general social, economic and entrepreneurial conditions, on the one side, and the results of economic activities at the level of national economy on the other side, gives a whole, systematically and methodologically well established understanding of entrepreneurship as a significant factor of the cited environment. Thus, available data of the GEM project allow analysis and identification of potential specific group of transition countries compared to other countries with different development levels in terms of the achieved level of economic development, growth and size and structure of entrepreneurial activity by using the application of statistical methods for determining differences between groups using MANOVA, ANOVA and discriminant analysis. The results of this study showed that the group of transition countries show specific differences in terms of the achieved level of development, the level of economic growth and the size and structure of entrepreneurial activity as a special economic area with a high degree of homogeneity with respect to the observed phenomena, and selected variables in comparison to other groups of countries. Not all of this means that the entrepreneurship in less developed countries, in this case, transitional countries, should be discouraged for their contribution to economic development because of the identified environmental limits; on the contrary, small businesses and entrepreneurial projects represent the driving force to go through crises and the factor of economic stabilization in transitional countries.

The essential research intention in this work is oriented toward considering the nature of entrepreneurial activities regarding to the volume of representation, according to some stages of the entrepreneurial process for defined groups of countries, different development degree in crisis conditions. The analysis of research data has drawn some conclusions, which have largely confirmed hypotheses. Obtained results, after the application of adequate statistical procedures, emphasize the existence of negative correlation, degree of economic development and the rate of economic growth. They are partly explained by the place and causes of analysed crisis circumstances, the degree of integrity of financial and economic systems, as well as the heterogeneous economic structure, as the main resistance to negative economic trends. The defined groups of countries of different development degrees show different differences in all the degrees of the entrepreneurial process. There is a positive correlation between the volume of entrepreneurial activities and the rate of economic growth, but on behalf of the countries of the lower development degree. Crisis conditions in the least developed countries generate an additional pressure on entrepreneurial activities; while the relatively stable environment of highly developed countries enables some individuals to find business possibilities outside the entrepreneurial sector.
