The link between personality,aggressive driving,and risky driving outcomes – testing a theoretical model

This study tested a theoretical model of the relationship between the Big Five Personality Factors, aggressive driving and ‘risky driving outcomes’ (accidents, traffic tickets, and license suspension). It also tested the mediation effect of aggressive driving in the relationship between the five factor personality model and risky driving outcomes. Structural equation modeling was used to analyze the 293 participants’ responses. Bivariate correlations showed that aggressive driving was negatively related to emotional stability, agreeableness, and conscientiousness and positively related to risky driving outcomes. Agreeableness was negatively related to accidents, tickets, and license suspension. Conscientiousness was negatively related to tickets. The structural model was supported by data in which agreeableness predicted risky driving outcomes. Emotional stability, agreeableness, and conscientiousness predicted aggressive driving, which in turn predicted risky driving outcomes. Aggressive driving was shown to be a mediator in the relationship between agreeableness and risky driving outcomes.     

Pricing of collectibles: Baedeker guidebooks

We analyze the prices of Baedeker guidebooks issued between 1828 and 1945 in the English, French and German languages. We compile a repeat sales regression index of eBay hammer prices, which reveals a common factor in Baedeker guidebook prices. We find mixed evidence on the underperformance of masterpieces (defined as the most expensive guidebooks). No significant difference is found between the average returns of masters and those of non-masters; however, under a five-factor asset-pricing model consisting of Carhart's four factors and the Pástor–Stambaugh liquidity factor, only masterpieces exhibit significant underperformance. The average price levels of the US, UK and Continental European Baedeker markets do not differ significantly, indicating that the law of one price cannot be rejected. The Baedeker market posts significant negative abnormal returns between 2005 and 2009; however, this result is not found for returns of German-language and non-master guidebooks.     

Meta-analysis categorization of EU countries in the context of corporate income tax

The corporate income tax is a corporate tax which aggregates economic, political and social aspects. The paper focuses on identification, analysis and assessment of homogenous EU countries groups, which show the common characteristics in the field of corporate taxation based on the selected segmentation criteria. Within the statistical meta-analysis in this paper some several methodical approaches were used: variants of agglomerative hierarchical cluster analysis, k-means method and fuzzy c-means and also multidimensional scaling method are implemented and compared. The purpose of this research is, in the context of theoretical implication to provide a synthesis of knowledge and empirical evidence about selected determinants of corporate taxation, and to verify the applicability of the clustering methods when gaining knowledge in the field of taxation. In the context of practical implication is the main purpose of this research the categorization of European countries into economically meaningful clusters, based on their similarity in corporate taxation, and to assess the convergence of European countries in corporate taxation. Results of provided cluster analysis are five groups of multidimensional objects with distinctive characteristics: nominal and effective corporate tax rate, economic performance and the level of debt.     

Translating single project management knowledge to project programs

Over the past decade, the efficient implementation of project programs became of great importance. Many authors are concerned with improving the professionalism of implementing project programs, and most of them identify context‐related factors that are considered the bases of successful implementation. However, little has been written on how to use the project management toolkit in project programs. In mid‐2007, a research program was initiated to highlight the role of the single project management toolkit in implementing programs. During the research, both case‐based and interview‐based research methods were used. The primary question addressed in this article is how to translate single project management knowledge to program management.
