TY - JOUR A1 - Prieto-González, Lisardo A1 - Tamm, Gerrit A1 - Stantchev, Vladimir T1 - Governance of cloud computing: semantic aspects and cloud service brokers JF - International Journal of Web and Grid Services N2 - This paper provides an overview of cloud governance aspects based on a representative survey of trends in the perception, assessment and adoption of cloud computing within the enterprise. The survey was conducted through a twofold research approach and combined a meta-study of existing and published empirical studies with an own empirical study within a representative group of European and international enterprises. We consider governance through the prism of adoption drivers and focus on the role of cloud brokers and cloud marketplaces more specifically, as well as the inclusion of semantic based strategies oriented to enhance the quality of service offered by cloud service brokers.

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.

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.

Hier stehen Fragen des Vertragsschlusses im Internet, der Haftung für Inhalte unter Berücksichtigung domain- und markenrechtlicher Fragen sowie der Datenschutz, der Schutz von geistigem Eigentum und der faire Umgang im Wettbewerb im Mittelpunkt. Zunehmend verbindet sich das „Internet der Dienste“ jedoch mit dem „Internet der Dinge“. Auch die mit diesem „Internet der Zukunft“ verbundenen rechtlichen Probleme – wie Big Data oder der Vertragsschluss Mensch-Maschine – werden aufgegriffen. Dieses Buch erschließt das Internet für den E-Commerce aus rechtlicher Sicht. Es zeigt Unternehmen wie Verbrauchern ihre diesbezüglichen Rechte, Pflichten und Verantwortlichkeiten auf. Zielgruppe sind Praktiker sowie Studierende aus allen Fachrichtungen. Anhand eines durchgehenden Beispielfalls und der aktuellen Rechtsprechung werden die verschiedenen Themen anschaulich dargestellt.

About one third of all hospital-acquired patient damages are due to medication errors. The aim of our interdisciplinary project “Risk Management in Hospitals” is to analyze the behavior of the various key players in the fields of medical care, human resources, supply and IT-systems in the context of various simulated risk scenarios as well as to develop adequate risk management tools. In this abstract, the first Results on medication errors are presented.

An effective defence against crises is only possible if the organizational resilience and the capacity to handle crises become part of the hospitals’ organizational culture. To become more resilient to crises, a raised awareness — especially in the area of human resource (HR) — is necessary. The aim of this paper is to contribute to the process robustness against crises through the identification and evaluation of relevant HR crises and their causations in hospitals. Qualitative and quantitative methods were combined to identify and evaluate crises in hospitals in the HR sector. A structured workshop with experts was conducted to identify HR crises and their descriptions, as well as causes and consequences for patients and hospitals. To evaluate the findings, an online survey was carried out to rate the occurrence (past, future) and dangerousness of each crisis. Six HR crises were identified in this study: staff shortages, acute loss of personnel following a pandemic, damage to reputation, insufficient communication during restructuring, bullying, and misuse of drugs. The highest occurrence probability in the future was seen in staff shortages, followed by acute loss of personnel following a pandemic. Staff shortages, damage to reputation, and acute loss of personnel following a pandemic were seen as the most dangerous crises. The study concludes that coping with HR crises in hospitals is existential for hospitals and requires increased awareness. The six HR crises identified occurred regularly in German hospitals in the past, and their occurrence probability for the future was rated as high.
