On measuring skewness and kurtosis

The paper considers some properties of measures of asymmetry and peakedness of one dimensional distributions. It points to some misconceptions of the first and the second Pearson coefficients, the measures of asymetry and shape, that frequently occur in introductory textbooks. Also it presents different ways for obtaining the estimated values for the coefficients of skewness and kurtosis and statistical tests which include them.     

Recommendations for improving the construct clarity of higher-order multidimensional constructs

In recent decades, there has been a proliferation of higher-order multidimensional constructs in the management and psychology literatures. Unfortunately, few guidelines have been presented for assessing the appropriateness of these constructs. In the current paper, the authors present seven recommendations for evaluating the construct clarity of multidimensional constructs. As an example, these guidelines are applied to existing multidimensional constructs, such as core self-evaluation and work engagement. The guidelines presented in this paper provide a roadmap for researchers interested in developing multidimensional constructs and identifying aspects of existing multidimensional constructs that are in need of improvement.     

Characteristics of labor market in Serbia - View on the labor demand on Belgrade and Banat labor markets

The labor market in Serbia is characterized by one of the highest unemployment rates of the working population （aged 15 to 64）. Also, it is notified that the unemployed level of the qualification is very low and that there isn＇t enough space in the existing formal educational system for any new introductions （such as prequalification courses, or lifelong educational concepts）. The research on the labor demand was aimed at assessing the state of the labor markets in the selected regions and at analyzing short-term demand for labor force. The analysis establishes： Which sectors of local/regional economy are being developed and are likely to require additional labor force in the next six months; which types of jobs are likely to be in demand in the aforementioned sectors; which additional knowledge and skills are needed for such occupations. The applied methodology also enabled to analyze information on vulnerable groups of unemployed, namely persons with disturbing factors in employment and the young unemployed of up to 24 years of age. In order to gather reliable data at regional level, a research was conducted on a stratified sample covering 1400 enterprises and some of the statistical labor market indicators were established indicating particularities of the labor markets in the surveyed regions -- Belgrade and Banat.
