The research approach is based on the Technology Acceptance Model (TAM). More specifically, the model is devoted to identifying barriers and enablers to the acceptance of these technologies. A questionnaire comprising three factors (Attitude toward using technology, Perceived ease of use and Perceived usefulness) was applied to a sample consisting of 121 higher education students. Results show that the perceived ease of use of cloud file hosting services is above that of LMS tools and services and that cloud file hosting services presented higher levels of perceived usefulness than standard learning management tools. In addition, attitude toward using cloud file hosting services is well above that of using LMS tools.

Maturity models for business processes aim at maintaining a distinct quality of processes and help to determine the maturity level of the processes and the company’s maturity. Previous research has shown the lack of transparency and standardization for maturity models. In particular, existing maturity models were not scientifically compared and evaluated among themselves. Uncertainty and unawareness in selection and application of adequate maturity models can be observed in applied science and practice. The aim of the scientific work was to evaluate existing business process maturity models in terms of strengths and weaknesses in order to provide a comprehensive and reliable knowledge-based on specific evaluation criteria setting. The conclusions have been used to take advantage of one of the pre-chosen models to measure the maturity of a business process. The examined models were CMMI, BPMM-OMG, PEMM and EDEN. The applied methodology consists of literature research, empirical findings and practical application. The empirical findings comprise a purpose-made questionnaire and an outcome weighted in terms of importance and / or appliance. A particular challenge of the research was to compare the different maturity models based on their criteria, scales and general scope.

However, past experiences have shown interoperability limitations in practice mainly due to information asymmetries on the Web Services markets. This Paper describes a service-oriented architecture for building Dynamic Value Webs in mobile environments using adaptive Location-Based Services. Our concept addresses the following three predominant difficulties: (1) service adaptivity to changing conditions in mobile environments, (2) interoperability including higher levels of semantics, and (3) assuring trustworthiness to all affected parties.

This paper investigates to what effect service-oriented IT management has already been put into place in European companies. Benefit and cost categories of integrating service-oriented principles into IT management processes are analyzed. Additionally success factors for implementing serviceoriented IT management are investigated. For this purpose, six case studies were conducted. The situation of IT management before and after implementation was analyzed and comments are made on the corresponding transformation projects. Based on the case studies, this paper shows three typical benefit categories of service-oriented IT management. Eight cost categories for implementing and operating service-oriented IT management processes are discussed and six success factors of pertinent re-organization projects are identified. Findings can serve as guidelines for other IT organizations and can be used as enabler for getting informed decisions regarding the initiation of service-oriented IT management. Finally, the article highlights four current trends for service-oriented IT management and further research is outlined.

Internationale Tagung Wirtschaftsinformatik, Bamberg N2 - Die Umsetzung von IT-Service-Support-Prozessen auf der Basis des Referenzmodells IT Infrastructure Library (ITIL) geschieht in vielen Unternehmen derzeit mit hoher Priorität. Obwohl zur Unterstützung der Support-Prozesse eine Vielzahl von Softwarelösungen zur Verfügung stehen, basieren diese heute nicht auf Service-orientierten-Architekturen. Die Vorteile einer Service-orientierten-Architektur werden daher im Rahmen des IT-Service-Supports nicht genutzt. Der Beitrag zeigt am Beispiel eines zentralen ITIL-Support-Prozesses, dem Incident-Management, wie dieser technisch auf der Basis von Web-Services umgesetzt werden kann. Die Grundlage bilden sechs Fallstudien, in denen die Gestaltung ITIL-basierter Support-Prozesse untersucht wurde. Aufbauend auf den Fallstudien wird ein generischer Incident-Management-Prozess definiert und mit Hilfe von Web-Services umgesetzt. Dabei kommen sowohl atomare als auch aggregierte Web-Services zum Einsatz. Für ein konkretes Service-Anliegen wird der Prozessablauf grafisch beschrieben. Die Umsetzung erfolgt exemplarisch unter Zuhilfenahme der Web Services Description Language (WSDL).

Access, affordability and quality to proper healthcare is a great challenge in world society. With the utilization of smart sensors, there are possibilities to improve the quality of healthcare services whenever needed. Hence, such smart items services lead to economic advantages for the whole healthcare system. Keeping in mind these opportunities as well as challenges such as security or legal issues, it is important to bring healthcare and IT together. As a result, healthcare business processes need to be modeled in order to provide IT solutions tailored for practice-oriented applications. In this paper, we present a three-level architecture for a smart healthcare infrastructure. Our approach is based on recent literature work and results from conducted expert interviews with healthcare specialists and IT professionals. To demonstrate the applicability of this architecture model, we provide an example use-case as a template for any kind of smart sensor-based healthcare infrastructure.

However, Europe is lagging behind the US economy, where startup ecosystems are thriving for decades, such as the Silicon Valley. One reason for that is that Europe comprises of many small markets, each with different legislation and language, which creates barriers for local startups to scale fast. The European startup ecosystem is very fragmented and in order to be competitive on the global markets, collaboration between different startup cities is necessary to develop. The purpose of this study is to explore the collaboration between the two tech startup ecosystems in Berlin (Germany) and Sofia (Bulgaria). The approach is to measure and analyse the current collaboration of entrepreneurs and investors from both ecosystems by collecting quantitative data about their collaboration behaviour. Data is collected via an online survey among participants from both ecosystems. Then, the data is used to identify which pairs of actors are most likely to become the catalysts of collaboration in the next 5 years. Based on that, three alternative scenarios for the future collaboration between Berlin and Sofia are designed. Scenario 1 assumes the collaboration between entrepreneurs from both ecosystems will grow fast and stimulate the collaboration between other actors from Berlin and Sofia. Scenario 2 identifies there is an established collaborative relationship between investors from Berlin and investors from Sofia. Based on that, the prediction is that in the long term many co-investments will occur, and this will generally encourage other actors from the two cities to collaborate. Scenario 3 is based on the assumption that Sofia will position itself as a seed-stage startup hub. The low cost of living and low competition for seed capital can eventually attract Berlin entrepreneurs to collaborate more with Sofia investors.

A number of important studies point out the necessity of improvements in the field of education. Using learning management systems might be a chance for institutes of higher education to face the demands of today. In this paper we evaluate the need of learning management systems for higher education organisations. A value chain for organisations of higher education has been developed to categorize and to describe generic task. By conducting an empirical analysis through the academic task carriers (professors, students and administration department) we could identify the need for supporting each task by learning management system. The paper aims to describe a generic evaluation method for learning management systems. A comprehensive description of the evaluation method and results of the empirical analysis are presented in detail.

Utilization of computer has benefited the employment market on vast scale, depending on the requirements of a particular business, its size and financial capabilities, and the intention to use. Furthermore, unparalleled technologies, such as cloud computing and smart technologies has directly affected demand for modern day labour. Nowadays, the utility model of cloud computing made it more popular and a favourite choice for the institutes to free up their internal resources and also reduce the number of administrative staff needed to maintain it. With certain kinds of offerings, institutes operating at small scales are also benefitting, which was almost impossible only a decade ago. Given that, the successful utilization of cloud computing remains a topic of extra ordinary importance among the scholars, experts, interested groups and several other institutions, and is defined in different ways according to their particular understanding and usage. But cloud is best defined by National institutes of standard and technology.

In this paper, authors propose factors for different layers of a framework to manage scarce resources in IT-departments. These layers aim for different relevant dimensions of employee satisfaction like wages, psychological development of employees and work life balance. Authors present a structured literature review to screen relevant publications on the topic. This paper offers white range of different factors regarding the management of labour shortage and highly skilled employees in companies which can be used to build a holistic model or framework to solve the challenges of the upcoming demographic change in Europe. Although the topic is quite popular in scientific literature, there is not a study devoted to identify these factors in organizational contexts. This paper is aimed to bridge this gap.

Recently, technology in general and CRM and social networks in particular have been identified as important enablers for loyalty in tourism. This paper presents POST-VIA 360, a platform devoted to support the whole life-cycle of tourism loyalty after the first visit. The system is designed to collect data from the initial visit by means of pervasive approaches. Once data is analysed, POST-VIA 360 produces accurate after visit data and, once returned, is able to offer relevant recommendations based on positioning and bio-inspired recommender systems. To validate the system, a case study comparing recommendations from the POST-VIA 360 and a group of experts was conducted. Results show that the accuracy of system’s recommendations is remarkable compared to previous efforts in the field.
