Such particles can be convex as well as concave. We use the geometrical optics approximation to study the light scattering from 3-foci particles. Non-zero elements of the scattering matrix are calculated for ensembles of randomly oriented independent transparent particles, m = n + i0. Several internal reflection orders are considered separately. It was found that the transmission-transmission (TT) and transmission-reflectance-transmission (TRT) components dominate in the formation of intensity of scattered light at large and small phase angles, respectively. We found a significant role of the total internal reflections of the TRT in the middle portion of the phase angle range. The main factors in the formation of positive linear polarization are the R and TRT component. The TT component is responsible for the formation of negative polarization branch at large phase angles.}}, author = {{Stankevich, Dmitriy and Hradyska, Larissa and Shkuratov, Yuriy and Grynko, Yevgen and Videen, Gorden and Förstner, Jens}}, issn = {{0022-4073}}, journal = {{Journal of Quantitative Spectroscopy and Radiative Transfer}}, keywords = {{tet_topic_scattering}}, pages = {{49}}, title = {{{Light scattering by 3-Foci convex and concave particles in the geometrical optics approximation}}}, doi = {{10.1016/j.jqsrt.2019.04.016}}, volume = {{231}}, year = {{2019}}, } @techreport{8873, abstract = {{We analyze a credence goods market adapted to a health care market with regulated prices, where physicians are heterogeneous regarding their fairness concerns. The opportunistic physicians only consider monetary incentives while the fair physicians, in addition to a monetary payoff, gain an non-monetary utility from being honest towards patients. We investigate how this heterogeneity affects the physicians’ equilibrium level of overcharging and the patients’ search for second opinions (which determines overall welfare). The impact of the heterogeneity on the fraud level is ambiguous and depends on several factors such as the size of the fairness utility, the share of fair physicians, the search level and the initial fraud level. Introducing heterogeneity does not affect the fraud or the search level when the share of fair physicians is small. However, when social welfare is not at its maximum, social welfare always increases if we introduce a sufficiently large share of fair physicians.}}, author = {{Heinzel, Joachim Maria Josef}}, keywords = {{credence goods, heterogeneous experts, fairness, overcharging}}, publisher = {{CIE Working Paper Series}}, title = {{{Credence Goods Markets with Fair and Opportunistic Experts}}}, volume = {{119}}, year = {{2019}}, } @article{8880, author = {{Yigitbas, Enes and Jovanovikj, Ivan and Sauer, Stefan and Engels, Gregor}}, journal = {{Softwaretechnik-Trends, Proceedings of the 21st Workshop Software-Reengineering & Evolution (WSRE) & 10th Workshop Design for Future (DFF)}}, number = {{2}}, pages = {{39--40}}, title = {{{Towards Model-based Development of Context-aware Augmented Reality Applications }}}, volume = {{39}}, year = {{2019}}, } @article{8892, author = {{Pelster, Matthias and Breitmayer, Bastian}}, issn = {{0167-2681}}, journal = {{Journal of Economic Behavior & Organization}}, pages = {{158--179}}, title = {{{Attracting attention from peers: Excitement in social trading}}}, doi = {{10.1016/j.jebo.2019.03.010}}, volume = {{161}}, year = {{2019}}, } @inbook{9599, author = {{Daymude, Joshua J. and Hinnenthal, Kristian and Richa, Andréa W. and Scheideler, Christian}}, booktitle = {{Distributed Computing by Mobile Entities, Current Research in Moving and Computing.}}, pages = {{615--681}}, publisher = {{Springer, Cham}}, title = {{{Computing by Programmable Particles}}}, doi = {{https://doi.org/10.1007/978-3-030-11072-7_22}}, year = {{2019}}, } @inproceedings{9613, abstract = {{The ability to openly evaluate products, locations and services is an achievement of the Web 2.0.

Resistance is expressed in various forms, including a lack of cooperation, workarounds, and physical sabotage. Workarounds, in particular, have a dual nature and can refer to both, undesirable behavior that contradicts organizational struc-ture and to desired organizational innovation. While antecedents and different forms of worka-rounds have been explored, literature has remained silent on how and why workarounds of an individual employee can affect activities performed by other employees and thereby, change work routines on an organizational level. Since employees’ day-to-day performances constitute the ostensive patterns of a routine, we argue that workarounds will not only impact performanc-es of adjacent routines, but also transform the organization as a social structure. With a prelim-inary set of qualitative data from 24 interviews, we used a multiple case study design to concep-tualize six patterns that illustrate how and why workarounds can spread through an organiza-tion. The patterns are systematized by a framework that considers three types of collaboration and two types of handoffs across routines.

First, research strands are disconnected, emphasizing either exploration or exploitation of service innovation, despite an organizations’ need to accelerate innovation cycles of exploring and exploiting services. Second, a new framework for ambidextrous service innovation is provided, inspired by the dynamism and generative mechanisms of the ontologically related concept of organizational routines. The framework adopts the perspective of a mutually constitutive relationship between exploring new and exploiting current resources, activities, and knowledge.
