MMB & DFT 2014 : Proceedings of the International Workshops ; Modeling, Analysis and Management of Social Networks and their Applications (SOCNET 2014) & Demand Modeling and Quantitative Analysis of Future Generation Energy Networks and Energy-Efficient Systems (FGENET 2014)

At present, a comprehensive set of measurement, modeling, analysis, simulation, and performance evaluation techniques are employed to investigate complex networks. A direct transfer of the developed engineering methodologies to related analysis and design tasks in next-generation energy networks, energy-efficient systems and social networks is enabled by a common mathematical foundation. The International Workshop on "Demand Modeling and Quantitative Analysis of Future Generation Energy Networks and Energy-Efficient Systems" (FGENET 2014) and the International Workshop on "Modeling, Analysis and Management of Social Networks and their Applications" (SOCNET 2014) were held on March 19, 2014, at University of Bamberg in Germany as satellite symposia of the 17th International GI/ITG Conference on "Measurement, Modelling and Evaluation of Computing Systems" and "Dependability and Fault-Tolerance" (MMB & DFT 2014). They dealt with current research issues in next-generation energy networks, smart grid communication architectures, energy-efficient systems, social networks and social media. The Proceedings of MMB & DFT 2014 International Workshops summarizes the contributions of 3 invited talks and 13 reviewed papers and intends to stimulate the readers’ future research in these vital areas of modern information societies.Gegenwärtig wird eine reichhaltige Klasse von Verfahren zur Messung, Modellierung, Analyse, Simulation und Leistungsbewertung komplexer Netze eingesetzt. Die unmittelbare Übertragung entwickelter Ingenieurmethoden auf verwandte Analyse- und Entwurfsaufgaben in Energienetzen der nächsten Generation, energieeffizienten Systemen und sozialen Netzwerken wird durch eine gemeinsame mathematische Basis ermöglicht. Die Internationalen Workshops "Demand Modeling and Quantitative Analysis of Future Generation Energy Net-works and Energy-Efficient Systems" (FGENET 2014) und "Modeling, Analysis and Management of Social Networks and their Applications" (SOCNET 2014) wurden am 19. März 2014 als angegliederte Symposien der 17. Internationalen GI/ITG Konferenz "Measurement, Modelling and Evaluation of Computing Systems" und "Dependability and Fault-Tolerance" (MMB & DFT 2014) an der Otto-Friedrich-Universität Bamberg in Deutschland veranstaltet. Es wurden aktuelle Forschungsfragen in Energienetzen der nächsten Generation, Smart Grid Kommunikationsarchitekturen, energieeffizienten Systemen, sozialen Netzwerken und sozialen Medien diskutiert. Der Tagungsband der Internationalen Workshops MMB & DFT 2014 fasst die Inhalte von 3 eingeladenen Vorträgen und 13 begutachteten Beiträgen zusammen und beabsichtigt, den Lesern Anregungen für ihre eigenen Forschungen auf diesen lebenswichtigen Gebieten moderner Informationsgesellschaften zu vermitteln

Influence of organizational culture and communication on the successful implementation of information technology in hospitals

In this paper, we report on a case study examining types of organizational culture influencing communication as an important factor in the study of successful IT adoption and implementation in health care. We observed a hospital organization and focused on technological innovations and the accompanying communication factors in the successful implementation of IT. The results demonstrate the importance of the organizational culture as an important factor in establishing well-balanced communication as a primary influence factor in the implementation of new technologies. Based on theoretical and empirical insights, we propose a model describing the relationship of organizational culture, communication, and the level of success in the implementation and adaptation of new IT systems in hospitals. © 2013 Springer-Verlag Berlin Heidelberg

Improving performance, perceived usability, and aesthetics with culturally adaptive user interfaces

When we investigate the usability and aesthetics of user interfaces, we rarely take into account that what users perceive as beautiful and usable strongly depends on their cultural background. In this paper, we argue that it is not feasible to design one interface that appeals to all users of an increasingly global audience. Instead, we propose to design culturally adaptive systems, which automatically generate personalized interfaces that correspond to cultural preferences. In an evaluation of one such system, we demonstrate that a majority of international participants preferred their personalized versions over a non-adapted interface of the same web site. Results show that users were 22% faster using the culturally adapted interface, needed less clicks, and made fewer errors, in line with subjective results demonstrating that they found the adapted version significantly easier to use. Our findings show that interfaces that adapt to cultural preferences can immensely increase the user experience

A Usability Study of an Enterprise Resource Planning System: A Case Study on SAP Business One

© 2019, Springer Nature Switzerland AG. The importance of Enterprise Resource Planning (ERP) system in modern business has created a demand for ERP consultants with the appropriate competencies to implement, maintain and support these systems such as SAP, Oracle, and Microsoft Dynamics. However, users of these systems encounter usability issues whilst learning to use the systems. Several studies have shown that the assessed user interface of these ERP systems resulted to poor usability and user dissatisfaction. Empirical studies on the usability of ERP systems, particularly for SAP B1 are limited on determining the critical success factors. This paper reports on the usability assessment of SAP B1 which investigates on the effects of the external dependent variables such as buttons, labels or terminologies, navigation, layout colors, user help and logical process. The experiment results provide considerable insights into the usability design issues of the SAP B1 Sales Module. Results were assessed by measuring the efficiency effectiveness and satisfaction followed by computing for their corresponding Single Usability Metric (SUM) for benchmarking. Thus, from the usability results of the redesigned user interface, there was a significant improvement on the sigma level
