Abstract: Environmental protection and environmental sustainability are becoming increasingly important factors in the hotel business and their competitiveness, in a market that brings numerous benefits. Environmental sustainability is, increasingly, considered one of the most important functions of the hotel business, as well as communication and marketing, which attracts a larger number of guests. Some of the key aspects of hotel environmental sustainability are performance and environmental sustainability indicators, as well as hotel management of environmental performance in order to establish efficiency in that process. The principal question arising is how environmentally sustainable business affects hotel performance, and what are the most important indicators of the environmental hotel business. The aim of this article is to offer an insight into, and analysis of, performance and indicators of the environmental sustainability of hotels through the relevant literature. A case study from Serbia is used to point out the complexity and the significance of these indicators in the hotel business, as well as to emphasise the importance of environmental reports in the case of Serbia. The findings of our study are significant because they help hotel managers identify new opportunities for employing more sustainable processes for saving resources.

Abstract: The increasing number of network-shaped domains calls for the use of graph database technology, where there are continuous efforts to develop mechanisms to address domain challenges. Relationships as 'first-class citizens' in graph databases can play an important role in studying the structural and behavioural characteristics of the domain. In this dissertation, we focus on studying the cardinality constraints mechanism, which also exploits the edges of the underlying property graph. The results of our literature review indicate an obvious research gap when it comes to concepts and approaches for specifying and representing complex cardinality constraints for graph databases validated in practice. To address this gap, we present a novel and comprehensive approach called the k-vertex cardinality constraints model for enforcing higher-order cardinality constraints rules on edges, which capture domain-related business rules of varying complexity. In our formal k-vertex cardinality constraint concept definition, we go beyond simple patterns formed between two nodes and employ more complex structures such as hypernodes, which consist of nodes connected by edges. We formally introduce the concept of k-vertex cardinality constraints and their properties as well as the property graph-based model used for their representation. Our k-vertex model includes the k-vertex cardinality constraint specification by following a pre-defined syntax followed by a visual representation through a property graph-based data model and a set of algorithms for the implementation of basic operations relevant for working with k-vertex cardinality constraints. In the practical part of the dissertation, we evaluate the applicability of the k-vertex model on use cases by carrying two separate case studies where we present how the model can be implemented on fraud detection and data classification use cases. We build a set of relevant k-vertex cardinality constraints based on real data and explain how each step of our approach is to be done. The results obtained from the case studies prove that the k-vertex model is entirely suitable to represent complex business rules as cardinality constraints and can be used to enforce these cardinality constraints in real-world business scenarios. Next, we analyze the performance efficiency of our model on inserting new edges into graph databases with varying number of edges and outgoing node degree and compare it against the case when there is no cardinality constraints checking. The results of the statistical analysis confirm a stable performance of the k-vertex model on varying datasets when compared against a case with no cardinality constraints checking. The k-vertex model shows no significant performance effect on property graphs with varying complexity and it is able to serve as a cardinality constraints enforcement mechanism without large effects on the database performance.

Abstract: The article presents results of research on the identification and evaluation of barriers faced by successors in family businesses during the first process of succession. The analysis of empirical material used grey systems theory, which was considered as an equivalent for the analysis of small samples and qualitative research. While conducting the literature review and empirical study, the authors concentrated on (a) the identification of barriers in the development of family firms and (b) eliciting the perspective of the new generation of owners in family firms entering the succession process through an empirical analysis of the assessed level of risk in relationships with family and business.

Abstract: Companies use different marketing communication activities in order to communicate with their environment. Their decisions to use a specific activity are often the result of past experiences, habits or certain influences. Measurements related to the efficiency of their communication method, as well as the analysis concerning the effect of using a specific kind of marketing communication activity on different business success determinants are usually neglected. In this article, authors provide an analysis of a correlation between the use of a specific marketing communication activity and 13 different business success variables. Based on the research, it could be concluded that the net business result for the accounting period can be influenced by using printed advertisements in newspapers, radio commercials, press conferences, newsletters and sponsorship. Net return on assets showed a positive correlation with printed advertisements in newspapers and press conferences. Printed advertisements in newspapers and radio commercials have proved to influence net sales and, last but not least, authors discovered that the return on equity can be influenced by organizing press conferences and, by using leaflets, companies can expect to raise the net sales growth index.

Abstract: Theories of organization and management have offered several concepts and models indicating that organizational values are an important factor in running organizations. A still unexplained question concerns the creation of balanced organizational values which can support the achievement of diversified and even seemingly incompatible goals of today's organizations. To explore balanced organizational values in contemporary business practice, we tested two most frequently used value models, i.e., the Competing Values Framework and Schwartz’s values model, on the sample of the Fortune 100 companies. This dissertation proposes a new model of balanced organizational values named Mission-based model of organizational values which proved itself to be more appropriate for researching balanced values in contemporary business practice than the two most frequently used value models (the Competing Values Framework and Schwartz’s values model), thus supporting the first hypothesis of this dissertation. Given the particularities of balanced organizational values research, an instrument for measuring organizational values was developed to suit the specific needs of this research. In order to test the research hypotheses, a research in 24 Croatian companies was conducted. In each of these companies, between 27 and 50 employees were surveyed giving a total sample size of 874 respondents. The results of statistical analysis performed to test the second hypothesis, as well as the related sub-hypotheses, indicate that the degree of imbalance of organizational values has no significant effect on the higher level of organizational commitment. The same applies to the two separate components of organizational commitment—affective and normative. However, the existence of medium-sized negative correlation between the degree of imbalance of organizational values and continuance component of organizational commitment was determined. The testing results of the third hypothesis, as well as the related sub-hypotheses, indicate that organizations with balanced organizational values are, in general, more effective than organizations with imbalanced values. Moreover, this correlation was found not only for the overall level of organizational effectiveness, but also for the most perspectives of organizational effectiveness based on the Balanced Scorecard approach. To conclude, this dissertation contributes to a better understanding of the role of organizational values in business, especially emphasizing the importance and role of balanced organizational values. Mission-based model of organizational values, developed within this dissertation, follows the findings of the most used models, integrating and upgrading them with new cognitions based on selected scientific knowledge and experience from business practice. And most importantly, this dissertation presents an empirical confirmation of the importance of balancing organizational values as one of the preconditions for successful business.
