Karel Barák, František Dařena, Jan Žižka
European Journal of Business Science and Technology 2015, 1(2):83-92 | DOI: 10.11118/ejobsat.v1i2.27 
The paper presents a procedure that helps in revealing topics hidden in large collections of textual documents (such as customer reviews) related to a certain group of products or services. Together with identification of the groups containing the topics the lists of important expressions is presented which helps in understanding what characterizes these aspects most typically from the semantic point of view. The procedure includes determining an appropriate number of groups representing the prevailing topics, partitioning the documents into a desired number of groups using clustering, extracting significant typical features of documents from each...

Jakub Berčík, Elena Horská, Johana Paluchová, Katarína Neomániová
European Journal of Business Science and Technology 2015, 1(2):93-103 | DOI: 10.11118/ejobsat.v1i2.28
In this article we evaluate three chosen restaurants in Nitra city from the perspective of visual proposal of chosen communication tool, which can be effective for influencing of restaurant's guests to visit each restaurant. It might be done through techniques and methods used in neuroscience. The consumer neuroscience is the area of marketing that studies the sensomotoric, cognitive and affective consumer's reactions on different marketing stimulus. In this article, we use Eye Tracker as one of biometric methods and we research, how restaurant's leaflets can be attractive for guests and in the conclusion we suggest some tips for marketing communication...

Václav Klepáč
European Journal of Business Science and Technology 2015, 1(2):104-113 | DOI: 10.11118/ejobsat.v1i2.30
We apply standard Merton and enhanced Merton-D-Vine copula model for the measurement of credit risk on the basis of accounting and stock market data for 4 companies from Prague Stock Exchange, in the midterm horizon of 4 years. Basic Merton structural credit model is based on assumption that firm equity is European option on company assets. Consequently enhanced Merton model take in account market data, dependence between daily returns and its volatility and helps to evaluate and project the credit quality of selected companies, i.e. correlation between assets trajectories through copulas. From our and previous results it is obvious that basic Merton...
Informality, Tax Evasion and the Quality of Business Environment: Evidence from South Caucasian Countries
Orkhan Nadirov, Khatai Aliyev
European Journal of Business Science and Technology 2015, 1(2):114-127 | DOI: 10.11118/ejobsat.v1i2.17
In many transition countries, a considerable part of economic activity takes place in the informal sector. On the other hand, tax evasion constitutes a major problem and causes improvements to all levels of the informal sector in which the volume of the informal sector in transition countries is much higher than in developed countries. Previous works have examined separately both the determinants of the size of the informal sector and the determinants of tax evasion for transition countries. But, this paper complements these significant works by examining cross sectional analysis based on firm-level data for South Caucasian countries. In addition,...
Selected Personality Characteristics as Predictors of Emotional Consumer Behaviour
Jana Rybanská
European Journal of Business Science and Technology 2015, 1(2):128-136 | DOI: 10.11118/ejobsat.v1i2.26
Many consumers believe that choices they make result from rational analysis of available alternatives. In reality, however, emotions greatly influence and determine our behaviour and decisionmaking also on the market of products and services. The main aim of this paper is to show the relationship between selected personality traits and emotional consumer behaviour. We used two psychological tests (Eysenck personality questionnaire and author's scale of emotionality) and tested several factors that might have influenced emotional consumer reactions. We found out that two of three tested personality predictors are significant - extroversion and neuroticism....

Oladipupo Muhrtala Tijani, Mubaraq Sanni, Karimu Adebayo Ishola
European Journal of Business Science and Technology 2015, 1(2):137-148 | DOI: 10.11118/ejobsat.v1i2.12
We examine whether the presence of outside directors with multiple boards seats influence firms related-parties transactions. These non-executive directors with vast skill, experience, knowledge, prestige and shared networks are part of major Boards Committees responsible for key corporate policies, strategy and management. Subsequently, it remains an untested assumption whether the outcome of related parties' transactions are influenced by the presence of this class of 'busy directors'. We obtain data from 142 companies across five sectors between 2009 and 2014 and conduct analysis using a two-stage multiple regression. The results reveal that the...
Can Uppsala Model Explain the Internationalisation of Central European SMEs?
Marcela Tuzová, Martina Toulová, Jakub Straka, Lea Kubíčková
European Journal of Business Science and Technology 2015, 1(2):149-164 | DOI: 10.11118/ejobsat.v1i2.14
The aim of this paper is to scrutinize some aspects of the Uppsala model whose applicability for SMEs' internationalisation is often questioned. This model explains internationalisation as a sequential process based on learning in which an enterprise increases its international commitment in incremental steps (Johanson and Vahlne, 1977). The assumptions of Uppsala model are discussed in conditions of SMEs from different countries, namely the Czech Republic, Slovakia, Poland, Austria and Germany. The paper is based on primary data obtained by questionnaire survey performed in 2014. Respondents were small and medium-sized firms from the above mentioned...
