However, it is not clear whether and when firms can capture the potential value advantages of outsourcing business services. The purpose of this paper is to investigate the effects of different types of business service outsourcing on firm value. Design/methodology/approach The paper uses event study methodology to estimate the impact of business service outsourcing announcements on abnormal returns of publicly traded manufacturing companies in Europe. Findings External service outsourcing that directly affects the company’s customers leads to more favorable outcomes than internal service outsourcing. This effect is contingent on the strategic outsourcing intention, the service’s reliance on technology, and the choice of the outsourcing partner. Research limitations/implications Findings show that firm value depends critically on the service value it delivers to customers. Future research could explore further contingency variables, and investigate the role of service outsourcing networks and relationships. Practical implications The insights of this study help managers to decide why, how, and to whom they should outsource their business services, as well as how to justify their outsourcing decisions, and how to communicate them toward the financial markets. Originality/value This research sheds light on the value implications of outsourcing decisions. Two types of business service outsourcing are distinguished, namely, internal and external. Furthermore, the study enhances our understanding of a contingency perspective on service outsourcing decisions. }}, author = {{Eggert, Andreas and Böhm, Eva and Cramer, Christina}}, issn = {{1757-5818}}, journal = {{Journal of Service Management}}, keywords = {{Strategy and Management, Tourism, Leisure and Hospitality Management, Business, Management and Accounting (miscellaneous)}}, number = {{3}}, pages = {{476--498}}, publisher = {{Emerald}}, title = {{{Business service outsourcing in manufacturing firms: an event study}}}, doi = {{10.1108/josm-11-2016-0306}}, volume = {{28}}, year = {{2017}}, } @inproceedings{19, abstract = {{Version Control Systems (VCS) are a valuable tool for software development and document management.

We overcome this issue by designing and implementing a concept for cryptography-enforced access control which is transparent to the user. Use of field-tested schemes (end-to-end encryption, digital signatures) allows for strong security, while adoption of convergent encryption and content-defined chunking retains storage efficiency.

Using a large number of respondents in a controlled setting, FSs approximate complex and realistic judgment situations through so-called vignettes—that is, carefully designed descriptions of hypothetical people, social situations, or scenarios. Despite being rooted, and predominantly applied, in sociology, FSs are particularly promising for business and society (B&S) scholars. Given the multiplicity, inherent complexity, and sometimes fuzziness of B&S research objects, conventional research methods inevitably reach their limits. This article, therefore, systematically presents methodological and thematic opportunities for FS studies in B&S research. It is argued that FSs are well suited to dealing with the complex interplay of societal-, organizational-, and individual-level factors in B&S research and to studying the principles underlying human perceptions, attitudes, values, social norms, and (anticipated) behavior. The application of the FS method is illustrated based on a showcase example in the realm of socially responsible investments (SRIs). As the literature on the conceptualization of FSs is limited, methodological challenges are addressed to guide B&S researchers past the common methodological pitfalls. }}, author = {{Oll, Josua and Hahn, Rüdiger and Reimsbach, Daniel and Kotzian, Peter}}, issn = {{0007-6503}}, journal = {{Business & Society}}, keywords = {{Social Sciences (miscellaneous), Business, Management and Accounting (miscellaneous)}}, number = {{1}}, pages = {{26--59}}, publisher = {{SAGE Publications}}, title = {{{Tackling Complexity in Business and Society Research: The Methodological and Thematic Potential of Factorial Surveys}}}, doi = {{10.1177/0007650316645337}}, volume = {{57}}, year = {{2016}}, } @inproceedings{10673, author = {{Ho, Nam and Ahmed, Abdullah Fathi and Kaufmann, Paul and Platzner, Marco}}, booktitle = {{Proc.
