Different distributed trust concepts are applied to increase trust in such systems. However, these concepts yield to rather complex architectures which make it difficult to determine which component or system needs to be trusted. This paper presents a novel trust measurement method for distributed systems which enables the t identification of weak points in the overall system architecture. The measurement method includes the specification of a formal trust language and its representation by means of propositional logic formulas. The applicability of the proposed concepts is demonstrated by conducting a case study on the Internet voting system that was used in the 2007 parliamentary elections in Estonia."}],"extern":"1","publication":"Proceedings of the 23rd Bled eConference","ddc":["000"],"user_id":"61579","_id":"5598","has_accepted_license":"1","status":"public","oa":"1","citation":{"short":"M.

The empirical analysis uses comprehensive vulnerability data contained in the NIST National Vulnerability Database and a newly compiled data set of vulnerability patches.

Three research tasks are essential requisites on the path towards addressing this criticism: the synthesis of knowledge, the identification of lack of knowledge, and the proposition of paths for closing knowledge gaps. This paper considers each of these tasks by a) synthesizing key research findings based on a comprehensive literature review, b) identifying and unfolding key limitations of current research, and c) applying a decision-theoretic perspective, which opens new horizons to IS business value research and shows paths for overcoming the limitations. The adoption of this perspective results in a decision-theoretic foundation of IS business value research and includes the proposition of a consistent terminology and a research model that frames further research.","lang":"eng"}],"extern":"1","publication":"Proceedings of the 18th European Conference on Information Systems (ECIS 2010)","type":"conference","keyword":["Decision theory","IT value","IS assessment","IS evaluation"],"department":[{"_id":"277"}],"file":[{"creator":"hsiemes","date_created":"2018-12-11T15:24:22Z","relation":"main_file","date_updated":"2018-12-13T15:20:37Z","file_name":"IS business value - ECIS - Final Version.pdf","file_size":174368,"access_level":"open_access","file_id":"6193","content_type":"application/pdf"}],"date_created":"2018-11-14T14:24:25Z","date_updated":"2022-01-06T07:02:14Z","year":"2010","title":"A decision-theoretic foundation of IS business value research","author":[{"first_name":"Guido","last_name":"Schryen","full_name":"Schryen, Guido","id":"72850"},{"last_name":"Bodenstein","first_name":"Christian","full_name":"Bodenstein, Christian"}],"language":[{"iso":"eng"}]},{"series_title":"GI-Edition: lecture notes in informatics.

The proposed model is complementary to robabilistic approaches and useful in situations where probabilistic information is either unavailable or not appropriate to reliably predict future conditions. We ?rst present the speci?cation of a formal security language that allows to specify under which conditions a distributed system is protected against security violations. We show that each term of the security language can be transformed into an equivalent propositional logic term. Then we use propositional logic terms to de?ne a fuzzy set based decision model. This optimization model incorporates uncertainty with regard to the impact of investments on the achieved security levels of components of the distributed system. The model also accounts for budget and security constraints, in order to be applicable in practice.","lang":"eng"}],"publication":"Sicherheit 2010 : Sicherheit, Schutz und Zuverl{\\\"a}ssigkeit ; Konferenzband der 5.

This paper assumes that literature reviews, which represent a powerful instrument for the identification and synthesis of knowledge, have not tapped their full potential to address this issue due to deficiencies in methodology. The analysis of 18 literature reviews published in pertinent academic outlets during the past 20 years shows such deficiencies. Two of the most critical weaknesses identified are (1) the lack of theory use in most reviews and (2) a weak linkage of reviews, resulting in little progress in theory and framework development. The systematic identification of these weaknesses and the extraction of promising methodological examples from past literature are the main contributions of this work, which supports the composition of more effective literature reviews in future research."}],"extern":"1","date_created":"2018-11-14T14:36:26Z","file":[{"file_size":302340,"access_level":"open_access","file_name":"2010_Book_ScandinavianInformationSystems - Schryen.pdf","date_updated":"2018-12-13T15:17:00Z","relation":"main_file","content_type":"application/pdf","file_id":"6186","creator":"hsiemes","date_created":"2018-12-11T15:14:51Z"}],"department":[{"_id":"277"}],"type":"conference","keyword":["Literature review","Business value","Information systems","Methodology","Theory"],"author":[{"first_name":"Guido","last_name":"Schryen","full_name":"Schryen, Guido","id":"72850"}],"title":"An Analysis of Literature Reviews on IS Business Value: How Deficiencies in Methodology and Theory Use Resulted in Limited Effectiveness","year":"2010","date_updated":"2022-01-06T07:02:18Z","language":[{"iso":"eng"}]},{"department":[{"_id":"277"}],"keyword":["Business value","Information systems","Literature review","Meta review"],"type":"journal_article","date_created":"2018-11-14T14:38:02Z","file":[{"date_created":"2018-12-11T15:19:37Z","creator":"hsiemes","content_type":"application/pdf","file_id":"6187","date_updated":"2018-12-13T15:17:12Z","relation":"main_file","file_size":525443,"access_level":"open_access","file_name":"BISE-PreservingknowledgeonISbusinessvalue-Manuscript-1.pdf"}],"abstract":[{"lang":"eng","text":"The economic relevance of information systems has been studied for many years and has attracted an abundance of research papers.

Realisierbare Mischzeiten reichen von einigen Millisekunden bis zu Sekunden, wobei die vollständige Homogenisierung oft nicht sichergestellt ist. Werden kinetische Parameter chemischer Reaktionen dieses Zeitskalenbereichs ohne Berücksichtigung der Mischprozesse bestimmt, sind sie mischungsmaskiert und geben die inhärente chemische Kinetik nicht wieder. In dieser Arbeit wird die Validierung und Anwendung einer Methode zur Bestimmung inhärenter chemischer Kinetiken von in Flüssigphase ablaufenden chemischen Reaktionen im stationären, laminaren Flachbettmikroreaktor vorgestellt. Der verfolgte Ansatz basiert auf der mechanistischen Modellierung der Molmengen unter Berücksichtigung von Konvektion, Diffusion und Reaktion und der Bestimmung der unbekannten Parameter durch Anpassung des Modells an experimentell ermittelte Konzentrationsverläufe.","lang":"ger"}]}]
