Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. This model allows us to align different contributions of literature reviews with their underlying knowledge conversions - thereby building a bridge between the previously largely unconnected fields of literature reviews and epistemology. We evaluate the appropriateness of the model by conducting an empirical analysis of 173 IS literature reviews which were published in 39 pertinent IS journals between 2000 and 2014. Based on this analysis, we derive an epistemological taxonomy of IS literature reviews, which complements previously suggested typologies.}}, author = {{Schryen, Guido and Wagner, Gerit and Benlian, Alexander}}, booktitle = {{International Conference on Information Systems (ICIS)}}, keywords = {{Literature review, Research methods/methodology, Theory of knowledge}}, title = {{{Theory of Knowledge for Literature Reviews: An Epistemological Model, Taxonomy and Empirical Analysis of IS Literature}}}, year = {{2015}}, } @article{5622, author = {{Schryen, Guido and Rauchecker, Gerhard and Comes, Martina}}, journal = {{Business & Information Systems Engineering (BISE)}}, number = {{4}}, pages = {{243--259}}, publisher = {{Springer}}, title = {{{Resource Planning in Disaster Response - Decision Support Models and Methodologies}}}, volume = {{57}}, year = {{2015}}, } @article{5634, author = {{Schryen, Guido}}, journal = {{Communications of the AIS}}, number = {{Art 12}}, pages = {{286--325}}, publisher = {{Association for Information Systems (AIS); Association for Computing Machinery (ACM)}}, title = {{{Writing qualitative IS literature reviews ?

In GaAs, we observe experimentally strong electric field effects on the optical second (SHG) and third (THG) harmonic generation. The SHG signal for the laser-light k vector parallel to the [001] crystal axis is symmetry forbidden in the electric-dipole approximation, but can be induced by an applied electric field in the vicinity of the 1s exciton energy. Surprisingly, the THG signal, which is allowed in this geometry, is considerably reduced by the electric field. We develop a theory which provides good agreement with the experimental data. In particular, it shows that the optical nonlinearities for the 1s exciton resonance are modified in an electric field by the Stark effect, which mixes the 1s and 2p exciton states of opposite parity. This mixing acts in opposite way on the SHG and THG processes, as it leads to the appearance of forbidden SHG in (001)-oriented GaAs and decreases the crystallographic THG.}}, author = {{Brunne, D. and Lafrentz, M. and Pavlov, V.
