- ItemComplex agent-based models: application of a constructivism in the economic research(Technická Univerzita v Liberci, ) Bureš, Vladimír; Tučník, Petr; Ekonomická fakultaThe current state in research of economic systems is characterised by two prevailing issues. Firstly, study of economic systems is traditionally based on analytical and econometric tools, which have been the main arbiters of the veracity or plausibility of assumptions and hypotheses in economics. This approach has been proved to be highly suitable for theory development. Secondly, practical issues and necessity to support decision-making led to development of various modelling and simulation techniques or tools. However, majority of these approaches usually fail when coping with complexity. Furthermore, several main areas of interest can be identified in the business and economics modelling. Nevertheless, these areas are mostly independent due to their problem-based focusing on particular issues and their solutions. Depicted gaps might be bridged with the help of new modelling paradigms that have been established only recently. Application of agent-based modelling in the realm of economic systems is labelled as Agent-based Computational Economics (ACE). In particular sections of this paper results of experiments run on the novel model are described. The model is based on agents, which are described as a vector of several observed parameters, and four types of agents are used, namely consumer agent, factory agent, mining agent, and transportation agent. In addition, a colony is added as the fifth type of meta-agent. Scalability and configuration options of the model enable for various configuration and thus for conducting specific experiments. The presented system is already implemented as a prototype version in the NetLogo environment. The paper depicts two example scenarios, resource production and resource proximity, and offers interpretation of achieved results. Since most of the work done so far was focused on individual agents, group perspective as an important extension of ACE modelling is suggested as the further research and development direction.
- ItemThe GDPR at the Organizational Level: A Comparative Study of Eight European Countries(Technická Univerzita v Liberci, ) Zanker, Marek; Bureš, Vladimír; Cierniak-Emerych, Anna; Nehéz, Martin; Ekonomická fakultaThe General Data Protection Regulation, also known as the ‘gold standard’ or the ‘Magna Carta’ of cyber laws, is a European regulation that deals with rights in the area of privacy and focuses on data collection, storage and data processing. This manuscript presents the results of investigation in the business sphere from eight countries of the European Union. The research focused on awareness of the GDPR, costs associated with the GDPR, number of trainings, how data are secured and subjective evaluation. The questionnaire was used for data collection. The results show that the majority of employees concerned about the GDPR are able to define the GDPR correctly (64%). The correct identification of personal data is in 95% of cases. The vast majority of respondents (94%) assign the right to personal data protection to the GDPR. Most employees are trained in the GDPR once (46%) or twice (45%). Subsequently, the differences between these countries in some areas of the questionnaire survey were examined. For this purpose, Welch ANOVA with post-test Tukey HSD or Kruskal-Wallis test were used. As a result, knowledge about the personal data do not vary significantly between the countries. In the area of rights, the countries are not again statistically different. As for the number of security countries, statistics do not differ significantly. The subjective assessment of the GDPR is different across the countries. The GDPR is rated worst by companies in the Czech Republic and Slovakia. On the contrary, the GDPR is best perceived by companies in France and the United Kingdom.
- ItemTHE TOYOTA PRODUCTION SYSTEM – CZECH AND NIPPON CULTURAL PERSPECTIVES(Technická Univerzita v Liberci, ) Brunet-Thornton, Richard; Koža, Michal; Bureš, Vladimír; Ekonomická fakultaThis text focuses on the cultural relationships between Czech nationals employed at Japanese subsidiaries located in the Czech Republic. The paper analyses the possibilities of implementation of Toyota Production System within Japanese subsidiaries in Czech Republic. Moreover, it explores both the fi t between the cultural values of Czech and Japanese management and the values incorporated in the Toyota Production System, and the various relationships of employees of both cultures at a managerial and operational level. In order to conduct the study, 79 companies were contacted, and survey responses from a total of 108 Czech and Japanese employees were collected. Using a self-administered questionnaire created in Czech, English and Japanese language, the fi ndings of both common and divergent culturally-induced perspectives are analysed. Due to consistency with other cross-cultural studies Hofstede’s cultural dimensions are used as foundation. The discussion correlates the results to the extent that they are deemed appropriate. Hall’s low and high context models supplement the discussion, where applicable, to further explain issues relative to perception and communication. The dialogue is rich in the knowledge of Japanese methodologies of quality and overall management practice known in this case as the Toyota Production System. Data from the survey show that both Czech and Japanese employees have similar values related to work and neither job satisfaction nor number of confl icts is connected with TPS training. The manuscript concludes with both the list of existing research limitations that can be overcome in next studies, and an analysis of the need for further research within other crosscultural frameworks.
