Non-linear Affine Processes with Jumps

We present a probabilistic construction of $\mathbb{R}^d$-valued non-linear affine processes with jumps. Given a set $\Theta$ of affine parameters, we define a family of sublinear expectations on the Skorokhod space under which the canonical process $X$ is a (sublinear) Markov process with a non-linear generator. This yields a tractable model for Knightian uncertainty for which the sublinear expectation of a Markovian functional can be calculated via a partial integro-differential equation.Comment: 31 page

Manifestation of the magnetic depopulation of one-dimensional subbands in the optical absorption of acoustic magnetoplasmons in side-gated quantum wires

We have investigated experimentally and theoretically the far-infrared (FIR) absorption of gated, deep-mesa-etched GaAs/Al$_x$Ga$_{1-x}$As quantum wires. To overcome Kohn's theorem we have in particular prepared double-layered wires and studied the acoustic magnetoplasmon branch. We find oscillations in the magnetic-field dispersion of the acoustic plasmon which are traced back to the self-consistently screened density profile in its dependence on the magnetic depopulation of the one-dimensional subbands.Comment: LaTeX-file, 4 pages with 3 included ps-figures, to appear in Physica

DIGITALIZATION OF LOCAL OWNER OPERATED RETAIL OUTLETS: THE ROLE OF THE PERCEPTION OF COMPETITION AND CUSTOMER EXPECTATIONS

On the one hand, the increasing digitalization of commerce has put local owner operated retail outlets (LOOROs) under pressure to adapt their business models to the new technological and competitive environment as well as to the changing shopping habits of their customers. On the other hand, it also offers potential competitive advantages for them. This paper investigates the retailers’ perception of the competition and their perception of customer expectations, combined with a survey of the current use of digitalized services and the LOOROs readiness to increase the usage of digitalized services. Our results confirm that the perception of competitive pressure and customer expectations has a positive influence on LOOROs’ readiness to adopt new technologies and business models. But a significant number of the surveyed retailers underestimate the expectations of their customers and are reluctant to add digital services to their business portfolio. While our key findings are relevant insights for all LOOROs on their journey towards digitalization, our findings provide even more significant insights for all digital service providers aiming to take a slice of the still substantial market shares of LOOROs in rural areas

Local Shopping Platforms – Harnessing Locational Advantages for the Digital Transformation of Local Retail Outlets: A Content Analysis

Competitors and customers put Local Owner-Operated Retail Outlets(LOOROs) under digitalization pressure. Local Shopping Platforms (LSP), acting as intermediaries between LOOROs and their customers, explicitly make use of the locational strength of LOOROs and seem to be a promising vehicle to help LOOROs overcome their manifold digitalization difficulties. In this study, with the help of a structured content analysis of 27 LSPs in Germany, Switzerland, and the U.S., we analyze LSPs as local descendants of e-marketplaces and derive a functionality-based typology. Furthermore, we scrutinize how LSPs harness LOOROs locational advantages. Despite their visible role as interorganizational service-hubs and a low-level entry option to e-commerce for LOOROs, our results show that LSPs currently unduly focus on location-enabled services that support the online channel, while neglecting the potential of location-based services and the local stores as a Point of Sale (PoS)

Der Stage-Gate-Prozess als Instrument in der Entrepreneurship Education

Der Stage-Gate-Prozess ist in der Lage, als wirkungsstarke Klammer von Theorie und Praxis in der Entrepreneurship Education zu dienen. Der gestaffelte Prozessablauf lässt Lehrenden genug Raum, um offene Fragestellungen durch individuelle Themenschwerpunkte hervorzuheben. Gleichzeitig aber bietet der Stage-Gate-Prozess den Studierenden die Möglichkeit der selbständigen interdisziplinären Anwendung der im Studium erlernten Kenntnisse. Der Stage-Gate-Prozess ermöglicht es, erste Erfahrungen in unternehmerischen Entscheidungen und Handlungen im geschützten Hochschulraum zu erleben. Er vermittelt gerade auch den Studierenden, die bis dahin noch nicht über eine Unternehmensgründung nachgedacht haben, einen praxisnahen Einblick in die Potenziale und Herausforderungen der Produktentwicklung mit der Perspektive einer innovationsbasierten Unternehmensgründung. 19.06.2015 | Andreas Gerlach & Lars Bollweg (Soest

Development and Psychometric Properties of a Questionnaire Assessing Self-Reported Generic Health Literacy in Adolescence

Domanska OM, Bollweg TM, Loer A-K, Holmberg C, Schenk L, Jordan S. Development and Psychometric Properties of a Questionnaire Assessing Self-Reported Generic Health Literacy in Adolescence. International Journal of Environmental Research and Public Health. 2020;17(8): 2860.Health literacy is a promising approach to promoting health and preventing disease among children and adolescents. Promoting health literacy in early stages of life could contribute to reducing health inequalities. However, it is difficult to identify concrete needs for action as there are few age-adjusted measures to assess generic health literacy in young people. Our aim was to develop a multidimensional measure of health literacy in German to assess generic health literacy among 14- to 17-year-old adolescents, namely, the “Measurement of Health Literacy Among Adolescents Questionnaire” (MOHLAA-Q). The development process included two stages. Stage 1 comprised the development and validation using a literature review, two rounds of cognitive interviews, two focus groups and two rounds of expert assessments by health literacy experts. Stage 2 included a standard pretest (n = 625) of the questionnaire draft to examine the psychometric properties, reliability and different validity aspects. The MOHLAA-Q consists of 29 items in four scales: (A) “Dealing with health-related information (HLS-EU-Q12-adolescents-DE)”; (B) “Communication and interaction skills”, (C) “Attitudes toward one’s own health and health information”, and (D) “Health-related knowledge”. The confirmatory factor analysis indicated a multidimensional structure of the MOHLAA-Q. The internal consistency coefficients (Cronbach’s α) of the scales varied from 0.54 to 0.77. The development of the MOHLAA-Q constitutes a significant step towards the comprehensive measurement of adolescents’ health literacy. However, further research is necessary to re-examine its structural validity and to improve the internal consistency of two scales
