From its early stages, cloud computing has evolved from being a principal source for computing resources to a fully fledged alternative for rapid application deployment. Especially the service model Platform as a Service facilitates the hosting of scalable applications in the cloud by providing managed and highly automated application environments. Although most offerings are conceptually comparable to each other, the interfaces for application deployment and management vary greatly between vendors. Despite providing similar functionalities, technically different workflows and commands provoke vendor lock-in and hinder portability as well as interoperability. To that end, we present a unified interface for application deployment and management among cloud platforms. We validate our proposal with a reference implementation targeting four leading cloud platforms. The results show the feasibility of our approach and promote the possibility of portable DevOps scenarios in PaaS environments.
This study attempts to explore and triangulate with different methods the essence, definition, and methods of the grassroots practitioner term growth hacking. In the qualitative first part of our study, we conduct 12 expert informant interviews and a case study. In the quantitative second part of the study, we conduct a quantitative Twitter analysis to gain additional insights on the findings from the qualitative first part. As a result, we differentiate growth hacking from traditional marketing strategies and create a growth hacking process model depicting a sort of consensus of what can be thought to be integral parts of growth hacking.
This paper sheds light on cultural differences in the understanding of historical military events between Chinese, English, French, German, and Swedish Wikipedia language editions. Differences in understanding historical events can lead to intercultural misinterpretation and conflicts that cause negative consequences for international relations. We identified the most important historical events, mined cross-cultural relations, investigated word usage in war-related pages and performed network, complexity, and sentiment analysis. We also analyzed the usage of war-related words and the quantity of war-related events mentioned in different languages. Our findings suggest that World War I and World War II are the most important historical events within English, French, and German cultures and English Wikipedia contains more violence and war-related content, with a higher level of complexity than other language editions.
This volume is focused on the emerging concept of Collaborative Innovation Networks (COINs). COINs are at the core of collaborative knowledge networks, distributed communities taking advantage of the wide connectivity and the support of communication technologies, spanning beyond the organizational perimeter of companies on a global scale. It includes the refereed conference papers from the 6th International Conference on COINs, June 8-11, 2016, in Rome, Italy. It includes papers for both application areas of COINs, (1) optimizing organizational creativity and performance, and (2) discovering and predicting new trends by identifying COINs on the Web through online social media analysis. Papers at COINs16 combine a wide range of interdisciplinary fields such as social network analysis, group dynamics, design and visualization, information systems and the psychology and sociality of collaboration, and intercultural analysis through the lens of online social media. They will cover most recent advances in areas from leadership and collaboration, trend prediction and data mining, to social competence and Internet communication.
