Opis:
Aim. Based on similar studies, this research work aims to investigate the perception of students and Higher Education Institutions (HEIs) of learning about the importance of soft skills for their education and employment since these skills are increasingly sought-after by potential employers. Methods. The Kendall Tau b test and Mann Whitney U test have been applied to show the relationship between soft skills and job preparedness for students. This study investigates a selection of 100 students from a private HEI (UBT College) and 100 students from a public HEI (University “Haxhi Zeka”), both in Kosovo. A total of 200 valid responses were collected from July to September 2020. Goldsmith inventory for 15 soft skills has been distributed as a questionnaire has been distributed to the students of these universities. Results and conclusion. The research results indicate that in soft skills development of the UBT College students is significantly higher than the soft skills developed of the University “Haxhi Zeka” students. The findings also show that most of the students believe that their actual soft skills were at a less than the desired level. Practical application. This research implicates the Higher Education Institutions to consider the soft skills as an important tool for enhancing graduates’ employability. The results indicate the need to  reconsider the curriculum by embedding soft skills on it. The students’ perception on soft skills is a contribution not only for the universities considered in this research but also for all graduates in HEIs in Kosovo, since the curriculum does not change much among universities. According to Eurostat the unemployment youth rate in Kosovo is about 55.4% and for this reason the results will help the HEIs to rethink about their students’ future employment opportunities. Originality. This is the only study done in Kosovo about graduates’ soft skills and employment and it provides information about a concerning problem in the country. This paper suggests initiatives to upgrade students’ soft skills and to improve their perspective on their future employment.

Opis:
Nowadays, insurance contract reserves for coupled lives are considered jointly, which has a significant influence on the process of determining actuarial reserves. In this paper, conditional survival distributions of life insurance reserves are computed using copulas. Subsequently, the results are compared with an independence case. These calculations are based on selected Archimedean copulas and apply when the 'death of one individual' condition exists. The estimation outcome indicates that the insurer reserves calculated by means of Archimedean copulas are far more effective than those resulting from an independence assumption. The study demonstrates that copula-based dependency modelling improves the calculations of reserves made for actuarial purposes.

Spearman's rho
Opis:
The aim of the paper is two-fold. The first is to introduce, for any given partition of [R^2], the decomposition of Spearman's rho into three terms: bet~cveen, within and remainder. This decomposition, presented in Section 4, is strictly connected with that of the concentration index ar as introduced in Kowalczyk (1998), and with the decomposition of Kendall's tau as introduced in Kowalczyk and Niewiadomska-Bugaj (2000). Those earlier results are reminded in Sections 2 and 3. The second aim of the paper is to show and exemplify how one can use the decompositions of p* (Spearman's rho) and r (Kendall's tau) to analyse, decompose and compare m x m contingency tables with the same categories for the row variable and the column varable. The examples given in Section 5 concern social mobility tables with data from Britain and Poland. An important observation from the analysis of these data is that p* and r lead there to practically equivalent decompositions.

Opis:
From an investor's point of view, the appropriate selection of a fund is an important issue. When making such a choice, many elements should be considered. These include not only the fund's rate of return or its risk, but also the comparison of the fund's results with an appropriate benchmark. The aim of the research was to apply principal component analysis (PCA) to reduce the dimension of the indicators that help the investor in selecting a fund. The subject of the study was 15 equity funds that had been on the Polish market for many years. The research showed that it is possible to reduce the primary variables to two dimensions.
