Das Thema Querdenken ist so aktuell, spannend und interessant, dass sich Prof. Dr. Jens Böcker von der Hochschule Bonn-Rhein-Sieg nach unseren ersten Gesprächen dazu entschlossen hat, eine Projektarbeit für seine Studenten zu diesem Thema zu vergeben. Prof. Dr. Böcker ist Professor im Fachbereich Wirtschaftswissenschaften für BWL mit dem Schwerpunkt Marketing. Das „Forschungsprojekt Querdenken“ wurde von einer Gruppe Studenten um Manuel Hammes als Projektleiter im Sommersemester 2010 bei Prof. Dr. Böcker durchgeführt.
Hochschulbibliotheken haben heutzutage neben der traditionellen Aufgabe der Literaturversorgung und Informationsversorgung auch die Aufgabe, über ihre Website im Internet präsent zu sein und sich dort als zentraler Informationsanbieter zu positionieren. Die Webauftritte haben dabei die Funktionen als Zugangspunkt und Vermittlungsstelle für Informationen sowie als Werbemittel bzw. Instrument der Öffentlichkeitsarbeit. Im Hinblick auf die immer stärkere Benutzerorientierung der Bibliotheken werden die Webangebote von fünf Universitätsbibliotheken und einer Fachhochschulbibliothek nach diversen Kriterien analysiert: es wird herausgearbeitet, welche Inhalte auf den Websites zu finden sind, die Struktur wird näher betrachtet, ebenso wie die Navigationsmöglichkeiten, die Sprache und Textgestaltung und das Design.
This study presents the findings of a quantitative study on the use of Open Educational Resources (OER) and Open Educational Practices (OEP) in Higher Education and Adult Learning Institutions. The study is based on the results of an online survey targeted at four educational roles: educational policy makers; institutional policy makers/managers; educational professionals; and learners. The report encompasses five chapters and four annexes. Chapter I presents the survey and Chapter II discloses the main research questions and models. Chapter III characterises the universe of respondents. Chapter IV advances with a detailed survey analysis including an overview of key statistical data. Finally, Chapter V provides an exploratory in-depth analysis of some key issues: representations, attitudes and uses of OEP. The table of contents and the complete list of diagrams and tables can be found at the end of the report.
This paper addresses special skills, learners in Internet-based learning scenarios need. In self-directed learning scenarios, as most Internet-based learning scenarios are designed, learners bear the responsibility for their learning progress. To ease this task, institutions could prime the learners for the situation which may be quite different to their previous learning experiences. Basing on a Delphi-study, conducted with experts from the e-Learning sector in Germany, Austria, and Switzerland, the basic requirements have been determined.
The roadmap for quality and innovation through open educational practices has been conceived as a number of steps, a conceptual document, which can be used by organisations, leaners or professionals in order to improve their open educational practices. After the development of the core concept of the OPAL project, the guidelines for OEP, it became clear that these guidelines, would have to play an important part on the roadmap exercise, because they represent the very essence of how to foster and stimulate open educational practices. The roadmap therefore is meant to be an instrument, a tool which helps the different stakeholders to use the guidelines for their own context and purpose.
Adaptability as a Special Demand on Open Educational Resources: The Cultural Context of e-Learning
(2011)
Producing and providing Open Educational Resources (OERs) is driven by the concepts of openness and sharing. Although there already are a lot of free high-quality resources available, practitioners often rather rewrite learning resources than creatively embed (and thus, reuse) existing OERs. In this paper, we analyse the reasons for this in two different educational contexts. As a result of this analysis, we found that the uncertainty on possible adaptation needs is one of the major barriers. In order to overcome this barrier and make different learning contexts comparable, we analysed the context of learners and in particular, in the research project ‘Learning Culture’, we investigated the field of culturally motivated expectations and attitudes of learners. This paper shows the results of this research project and discusses which cultural issues should be taken into consideration when OERs are to be adapted from one to another cultural context.
In Anlehnung an die von Leidner und Kayworth (2006) durchgeführte Studie zum Umgang mit Kultur in der angelsächsischen Wissenschaftsdisziplin „Information Systems“ wurde eine entsprechende Literaturstudie für die gestaltungsorientierte Wirtschaftsinformatik des deutschen Sprachraums durchgeführt. In der Studie wurde in den Hauptorganen der Disziplin untersucht, in welcher Häufigkeit kulturelle Einflüsse auf Informationstechnologie thematisiert wurden, wie diese Einflüsse aufgearbeitet wurden und welche Referenzmodel-le/Referenzliteratur verwendet wurden. Nach einer kurzen Darstellung der gewählten Vorgehensweise werden die Ergebnisse und Beschränkungen der Studie präsentiert.
In an explorative study, we investigated on German schoolteachers how they use, reuse, produce and manage Open Educational Resources. The main questions in this research have been, what their motivators and barriers are in their use of Open Educational Resources, what others can learn from their Open Educational Practices, and what we can do to raise the dissemination level of OER in schools.
The usage of link quality based routing metrics significantly improves the quality of the chosen paths and by that the performance of the network. But, attackers may try to exploit link qualities for their purposes. Especially in tactical multi-hop networks, routing may fall prey to an attacker. Such routing attacks are a serious threat to communication. TOGBAD is a centralised approach, using topology graphs to detect routing attacks. In this paper, we enhance TOGBAD with the capability to detect fake link qualities. We use a Challenge/Response method to estimate the link qualities in the network. Based on this, we perform plausibility checks for the link qualities propagated by the nodes in the network. Furthermore, we study the impact of attackers propagating fake link qualities and present simulation results showing TOGBAD's detection rate.
Routing Attacks are a serious threat to communication in tactical MANETs. TOGBAD is a centralised approach, using topology graphs to detect such attacks. In this paper, we present TOGBAD's newly added wormhole detection capability. It is an adaptation of a wormhole detection method developed by Hu et al. This method is based on nodes' positions. We adapted it to the specific properties of tactical environments. Furthermore, we present simulation results which show TOGBAD's performance regarding the detection of wormhole attacks.
Projektmanagement im Mittelstand? Häufig Fehlanzeige, seufzen Beobachter. Mit modernen Methoden der Projektabwicklung, wie sie sich seit vielen Jahren etwa in Konzernen bewährt haben, wollen mittelständische Unternehmen wenig zu tun haben. Doch Vorsicht! Professor Uwe Braehmer warnt vor Pauschalurteilen. Einige Mittelständler beherrschen meisterhaft die Klaviatur des Projektmanagements. Andere erkennen derzeit neue Geschäftschancen durch Projektmanagement. Und wieder andere brauchen ein dem Mittelstand speziell angepasstes Projektmanagement. Professor Uwe Braehmer weiß: „Auf viele mittelständische Geschäftsführer wirkt Projektmanagement zu akademisch und zu groß dimensioniert.“ Bedarfsgerecht gestaltet könne es im Mittelstand eine wesentlich breitere Akzeptanz finden.
