One idea behind Open Educational Resources (OERs) is opening up the access to learning resources for stakeholders who were not the originally targeted users. Even though making educational resources available for the public already is a remarkable achievement, their usefulness often is limited to a very particular context because of unclear or missing appropriateness regarding other contexts. In this paper, contextual appropriateness is investigated as a special quality criterion for OERs. We will introduce barriers against the use of OERs and demands from the educational community that need to be addressed in order to overcome such barriers. We will show that the hitherto implemented quality standards for Technology Enhanced Learning do not yet fully support such particular demands and discuss which additional steps are required for the context of OERs. We conclude with an outlook and recommendations that can open up the full potential of OERs.
The aim of our research is preserving the learners’ initial motivation in educational settings by avoiding unnecessary conflicts that could decrease the learners’ joy of learning. In order to get a better understanding of particularly cul-ture-related factors that could jeopardize the learners’ motivation in international e-Learning scenarios, we devel-oped and exemplarily implemented the standardized questionnaire ‘Learning Culture’ in the Higher Education contexts of Germany and South Korea. Regarding motivation, we analysed how the students evaluated their own motivational predispositions towards outer influences, their purpose of learning and affections towards particular knowledge, and their strategies to deal with educational tasks that appear unmanageable or too difficult for them.

Botnets
(2013)
Malware poses one of the major threats to all currently operated computer systems. The scale of the problem becomes obvious by looking at the global economic loss caused by different kinds of malware, which is estimated to be more than US$ 10 billion every year. Botnets, a special kind of malware, are used to reap economic gains by criminals as well as for politically motivated activities. In contrast to other kinds of malware, botnets utilize a hidden communication channel to receive commands from their operator and communicate their current status. The ability to execute almost arbitrary commands on the infected machines makes botnets a general-purpose tool to perform malicious cyber-activities. (Verlagsangaben)
