Business students from a public university in Croatia participated in an international study on entrepreneurial self‐efficacy, identity, and education. The results of this preliminary empirical research indicate that the main predictors of the entrepreneurial intentions in Croatia are strength of entrepreneurial identity aspiration and entrepreneurial self‐efficacy. These two main constructs mediate the number of personal, situational, or contextual factors, including education. Empirical analysis supports the majority of Social Cognitive Career Theory hypothesized interaction between control variables and main constructs such as self‐efficacy, positive outcome expectations, and entrepreneurial identity. These findings thus fill the gap in the empirical evidence of the theoretical framework validity derived from different contexts.
In this paper, we consider the problem of searching for an optimal partition with the most appropriate number of clusters for an incomplete data set A ⊂ R n in which several outliers might occur. Special attention is given to the application of the Least Squares distance-like function. The procedure of preparing the incomplete data set and the outlier elimination procedure are proposed such that the clustering process gives acceptable solutions. Appropriate justifications with proof are provided for these procedures. An incremental algorithm for searching for optimal partitions with 2, 3,. .. clusters is applied on the prepared data set. After that, by using the Davies-Bouldin and the Calinski-Harabasz index the most appropriate number of clusters is determined. The whole procedure is organized as an algorithm given in the paper. In order to illustrate its applicability, the above steps are applied on the real data set of public buildings and their energy efficiency data, providing clear clusters that could be used for further modeling procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
