In comparison to real life human interaction, in which sentiments have been shown to have an influence on human behaviour, it is not yet completely understood which mechanisms explain how sentiments influence users in online environments. We develop a theoretical framework that tries to bridge the gap between social influence theories that focus on offline interactions on one hand and online interaction in social networks on the other hand. We then test our hypothesis about the influence and dissemination of sentiments in a quantitative analysis that is based on retrieved textual messages of communication patterns in over 12000 online social networks. Our empirical results suggest a general influence of sentiments on node communication patterns that is evidenced by increased occurrences of subsequent messages that express the same sentiment polarization. We interpret these findings and suggest future research to advance our currently limited theories that assume perceived and generalized social influence to path-dependent social influence models that consider actual behaviour.}}, author = {{Hillmann, Robert and Trier, Matthias}}, booktitle = {{ECIS 2013 Proceedings}}, isbn = {{9783834924421}}, keywords = {{Social Network Analysis, Sentiment Analysis, Communication Patterns}}, publisher = {{Association for Information Systems.

Securing this protocol is obviously a vital issue for any computer network. However, when it comes to cloud computing systems, the sensitivity of this issue rises, as the clients of system, release their data to the cloud. XML signature is employed to secure SOAP messages. However, there are also some weak points that have been identified, named as XML signature wrapping attacks, which have been categorized into four major groups; Simple Ancestry Context Attack, Optional element context attacks, Sibling Value Context Attack, Sibling Order Context. In this paper, two existing methods, for referencing the signed part of SOAP Message, named as ID referencing and XPath method, are analyzed and examined. In addition, a new method is proposed and tested, to secure the SOAP message. In the new method, the XML any signature wrapping attack is prevented by employing the concept of XML digital signature on the SOAP message. The results of conducted experiments show that the proposed method is approximately three times faster than the XPath method and even a little faster than ID.}}, author = {{Razzaghi Kouchaksaraei, Hadi and Chefranov, Alexander G.}}, journal = {{International Journal of Computer Science and Information Security}}, number = {{9}}, pages = {{1--6}}, title = {{{Countering Wrapping Attack on XML Signature in SOAP Message for Cloud Computing}}}, volume = {{11}}, year = {{2013}}, } @inproceedings{13645, author = {{Graf, Tobias and Schäfers, Lars and Platzner, Marco}}, booktitle = {{Proceedings of the International Conference on Computers and Games (CG)}}, publisher = {{Springer}}, title = {{{On Semeai Detection in Monte-Carlo Go.}}}, year = {{2013}}, } @inproceedings{24356, abstract = {{A fully integrated six-port receiver front-end at 120 GHz center frequency including a low-noise-amplifier, a passive six-port network, a VCO, and four direct converters is presented in this publication.
