Testing the sustainability of growth of the LJSEX in the January 2000 to May 2010 period
Aleš Ahčan, 2011, original scientific article

Abstract: In this paper we analyse the behaviour of the LJSEX, the main index of the Ljubljana Stock Exchange, in the period from January 2000 till May 2010. More precisely, we test for the presence of bubbles and antibubbles and try to determine whether or not a bubble could have been predicted (both the formation and the date of the bubble burst). Second, we also employ techniques used to model antibubbles to forecast the future behaviour of the LJSE index. Besides modelling index dynamics for the aforementioned period, we also seek to determine the factors that led to the bubble forming and later bursting. We find that the bubble could have been forecasted at least several months in advance. On the other hand, a very precise date of the crash seems harder to identify. By more closely analysing the interplay between interest rates, credit activity and the LJSEX, we conclude that there is a clear connection between decreasing interest rates, increased credit activity and the formation of a stock bubble. If there is a clear correlation between the early phase of a bubble and increased credit activity of the banking sector, the link between the end of the bubble and the restriction of credit activity is less pronounced. By fitting the extended antibubble model from (Johansen 1999a) we obtain the values of parameters that give us some indication of the future behaviour of the LJSEX. Based on these results we conclude that in the next few years we are likely to experience a period of increased volatility with no clear increasing or decreasing growth pattern.

Mobile wallets' business models
Uschi Buchinger, Heritiana Ranaivoson, Pieter Ballon, 2015, original scientific article

Abstract: Background and Purpose: Though Mobile Wallets have the potential to entirely substitute their physical predecessor, many Mobile Wallets narrow their operations to one particular feature. This might be because of strategic business- model design choices to position themselves strategically as intermediates between users and business partners (third parties) in more delimited markets. Thus, Mobile Wallet Applications (MWAs) often represent platforms in narrow two-sided market structures. Design/Methodology/Approach: The paper focuses on the economics of such platforms by the means of a business model analysis. It examines how business partners are integrated in four MWAs’ strategies: Key Ring, FidMe, Apple Passbook and Qustomer. Results: The paper shows that MWAs strive to incorporate not only a large quantity of partners but also such with a high brand value (quality of partners) in their organization design. These partners shape their service design since none of the platforms offer products or services themselves. Hence, MWAs are dependent on the third parties’ capacity and willingness to fulfill engagements and meet the customer demands. Conclusion: MWAs - though concerned with the inclusion and management of loyalty points and schemes - do not leverage the possibility to generate revenue via third parties’ loyalty points. Theoretically, MWAs could reward or redeem loyalty points themselves.

Does grade level matter for the assesment of business process management maturity?
Renata Gabryelczyk, 2016, original scientific article

Abstract: The purpose of this paper is to create and test the practical application of a business process management maturity assessment conducted at two different grade levels (management and professional level) in an organization. The conceptual framework for this research includes creating a business process maturity indicator (BPMI) for six process areas: strategy, documentation, optimization, implementation, execution, and controlling. The comparative analysis of the business process management maturity is performed using the BPMI on two cases: inside a single organization and the sector internally.

Environmental management of business processes
Vesna Čančer, 2000, original scientific article

Abstract: Since the decision-makers in enterprises will accept the goals of environmental management only if they are motivated enough, comprehensible and useful tools should be generated to support environmentally oriented business decision- making. For that reason, a general optimisation model of the multiphase business process is presented in this paper. This model includes the possibilities for an integrated approach to environmental protection so that it can be applied as a scenario by the business process simulation for the evaluation of environmentally oriented business decisions on business performance. Furthermore, development and application possibilities of the presented model are introduced. Some measures of resource efficiency are developed using the presented optimisation model.

Business system: sustainable development and anticipatory systems thinking
Vojko Potočan, Matjaž Mulej, 2002, original scientific article

Abstract: The existence and development of humankind depends a lot upon a co-ordinatet operation of all areas and levels of human activity. However, in either theory or practice we found no model of operation, which would offer a harmonized and target oriented development. A possible solution is offered by sustainable development, which tries to the define and carry out common goals of human kind with a holistic harmonization of humans activities at all levels of their living and behaviour. Companies belong to central institutions of the modern society and assentially co-create the sustainability of society. Companies endeavour (e.g. by simulation and planning) to prepare models of their goals and ways concerning their internal and external environment. On the basis of systems approach, we can define companies as business systems, which can best survive in a log-run on the basis of sustainable development. This business system's effort can also be supported by the application of the ancipatory systems thinking which can improve its planning methods, if it is holistic, understood as a future oriented mental activity made of its methodological approach, techniques, and modes of work. Its characteristics have a direct impact of holism of the definition of goals, on the orientation of operation, and hence achievement of the business system's results.
