- ItemPairwise judgments consistency impact on quality of multi-criteria group decision-making with AHP[S1](Technická Univerzita v Liberci, ) Kazibudzki, Pawel Tadeusz; Křupka, Jiří; Ekonomická fakultaThe scope of this research encompasses issues associated with group decision making (GDM) as the most challenging process which entails various viewpoints and preferences of individuals that must be taken into consideration and somehow combined into one meaningful outcome. When GDM is taken into consideration, the AHP seems to be a particularly attractive methodology. From the perspective of its applications, an existing research gap has been identified and examined in this research paper. Thus, the inconsistency of judgments impact on priority vector quality has been examined from the perspective of group decision making. Examination results generalize to the synthesized pairwise comparison matrix that is obtained on the basis of individual pairwise comparison matrices for all group members. The examination process has proceeded with the application of Monte Carlo simulations coded and executed in Wolfram Mathematica Software. Having in mind that a consistency index for the PCM denoting group preferences cannot be greater than the consistency index of the most inconsistent individual PCM it became possible to designate the credibility of the priority vector for the group on the basis of the most inconsistent individual PCM. It is emphasized that thus far only a few papers have dealt with the problem concerning the relation between a level of the pairwise judgments inconsistency and the degree of possible estimation errors for established vector of priority ratios. This research paper overcomes limitations of other examinations which distinguishes it from other papers and emphasizes its novelty.
- ItemFactors influencing consumer behaviour of Generation Y on the Czech wine market(Technická Univerzita v Liberci, ) Němcová, Jana; Staňková, Pavla; Ekonomická fakultaConsumer behaviour of Generation Y on the wine market is currently a topical issue. Generation Y is considered to be the future loyal consumers of wine and is therefore the future of the wine market. Wine-growing has a long tradition in the Czech Republic and, in particular, Moravian wines reach world level, as evidenced by a number of different awards and successes at winemaking competitions. The main aim of this paper is to identify the factors that affect the consumers of Generation Y when buying wine in the Czech Republic. The target group consists of respondents aged 18–25 who drink or at least buy wines. Primary data collection took place between February and September 2017 and was realized by a questionnaire survey. In total, 648 responses were collected. The Two-sample t-Test and the Pearson’s chi-squared ?2 test were used for statistical methods. Research has shown that young consumers clearly prefer white wine and their knowledge of wine is general for the large majority of respondents. The most common places of purchase are wine shops and supermarkets, and most of the respondents buying wines for meeting with friends, quiet sitting at home or for celebrations. Information about wine is obtained by young consumers most often from their families or friends, or from the operator in the wine shop. The most important factors for wine selection are previous purchase experience and references from family and friends, and then the information on a label, recommendations of the wine shop operator, price and colour of wine. Based on a comparison of the examined foreign sources in this area, it can be stated that wine consumers of Generation Y are not a homogeneous segment and more attention should be paid to the preferences of these young people.
- ItemAnalysis of the significance of eWOM on social media for companies[S1](Technická Univerzita v Liberci, ) Prantl, David; Mičík, Michal; Ekonomická fakultaIn recent years, social media have changed online communication. People share their views on individual companies as well as reviews of various products, and actively engage in discussions. Communication that spreads in this way is referred to as eWOM. The question is how important eWOM on social media can be for companies and what we can conclude based on eWOM. This research study aims to evaluate the significance of eWOM for companies in terms of the connection between eWOM and stock prices. Further, we explore the impact of eWOM on company website traffic. The research was conducted using a sample of 1,420,000 posts on social media sites mentioning companies that make up the components of the US30 stock market index. The results show that companies in the B2C segment with a higher share of positive posts compared to negative ones have seen a greater increase in stock prices. However, posts on social media mentioning companies in the B2B segment are not connected to the movement of stock prices of these companies. The research also revealed that 3 % of the total traffic on companies’ websites comes from social media sites. Based on the findings of the research, we can consider eWOM to be of major significance for companies in the B2C segment. These conclusions can be useful in predicting stock prices of particular companies on stock markets based on eWOM.
- ItemTrademark infringements in the domain .cz(Technická Univerzita v Liberci, ) Gongol, Tomáš; Ekonomická fakultaThe aim of this article is to fill a gap in an area that has not yet been closely examined in the Czech Republic and the world: examining the level of trademark infringement in relation to the basic elements of the logical architecture of the Internet, namely domain names, resp. Websites that are published on them. The article aims to determine the actual state and create a methodology of rapid, and to some extent automated detection of the collision of rights connected to trademarks with domain names. Not only for the large scope of the investigated subject has it focused on the sector of the automotive industry in particular. Given the aim of the work, it answers questions whether the phenomenon of trademark infringement on the Internet is rather a minor issue, which concerns only a fraction of domain names and websites; whether the domains names, resp. websites violating the trademark rights share any similar characters; whether it is possible to automate the search process of finding trademark infringements or if there is a way of finding general rules that can be a valuable help in this process. The first part of the article describes the used methodology, sources of available data and the way the data were worked with. The next part deals in detail with input data that are relevant for this article. It describes the ways the data were obtained and the constraints that needed to be overcome doing so. Basic statistical parameters of the input data are also mentioned. The third part is focused on the important findings found in input data relating to Czech domain names and trademarks used on the Internet followed by detail examination of the Czech domain names for the sector of the automotive industry. By using the defined indicators of a collision (the characters) the results of the article show that the domain names on which the trademark infringement has been committed, share the same set of characters that can be tested automatically by a computer program.
- ItemThe corporate social responsibility in the Romanian banking systém(Technická Univerzita v Liberci, ) Dinu, Vasile; Bunea, Mariana; Ekonomická fakultaFor the Romanian banking system, the corporate social responsibility (CSR) concept is not a new one, but its importance raises more and more awareness lately, the financial crisis of 2008 significantly bringing to surface the need to integrate the moral principles in the banking activity. The corporate social responsibility (CSR) takes into account the strategies that help companies to run their business in an ethical way, when talking about the relations to the other members of the society. The CSR can include a wide range of partnerships with the local communities, investments with a real social impact of the corporations (education, art, and environmental protection), developing relations between the firms and their clients, employees and their families. On one hand, the research aims at measuring the level of knowledge of the information regarding the corporate social responsibility of the banks in Romania in the timeframe 2015–2017 and on the other hand, to identify the possible relations between the CSR indexes and the financial performance, seen through the return on assets indicators (ROA) and return on equity indicators (ROE). In order to accomplish these objectives, the research methodology was based on the content analysis method, in order to identify the categories of corporate social responsibility that are included in the CSR index, obtained from the annual reports of the sustainability, published by the analyzed banks. To test the correlations of the dependent and independent variables, there were used correlation techniques and regression of the analyzed data, using the SPSS soft. Even with its limitations, this research can be a very strong source of information and reflection for the decision makers in the Romanian banking sector and more than that, can encourage an even bigger transparency of the information regarding the social and environment responsibility, as well as emphasizing of a performing management under all aspects that are related to the corporate social responsibility.
