JF - Business & information systems engineering : the international journal of Wirtschaftsinformatik N2 - "Deal of the Day" (DoD) platforms have quickly become popular by offering savings on local services, products and vacations. For merchants, these platforms represent a new marketing channel to advertise their products and services and attract new customers. DoD platform providers, however, struggle to maintaining a stable market share and profitability, because entry and switching costs are low. To sustain a competitive market position, DoD providers are looking for ways to build a loyal customer base. However, research examining the determinants of user loyalty in this novel context is scarce. To fill this gap, this study employs Grounded Theory methodology to develop a conceptual model of customer loyalty to a DoD provider. In the next step, qualitative insights are enriched and validated using quantitative data from a survey of 202 DoD users. The authors find that customer loyalty is in large part driven by monetary incentives, but can be eroded if impressions from merchant encounters are below expectations. In addition, enhancing the share of deals relevant for consumers, i.e. signal-to-noise ratio, and mitigating perceived risks of a transaction emerge as challenges. Beyond theoretical value, the results offer practical insights into how customer loyalty to a DoD provider can be promoted.

We prove that the near-inverse of such a sequence is unique; moreover, the relation of being near-inverses of each other is symmetric, i.e. if sequence g is the near-inverse of sequence f, then f is the near-inverse of g. There is a connection, by approximations, between near- inverses of sequences and inverses of continuous strictly increasing real-valued functions which can be exploited to derive simple expressions for near-inverses Y1 - 2006 UR - http://www.informaworld.com/openurl?genre=journal&issn=0020-7160 U6 - https://doi.org/10.1080/00207160500537801 SN - 0020-7160 ER - TY - CHAP A1 - Knoth, Alexander Henning A1 - Kiy, Alexander T1 - (Self-)confident through the introductory study phase with the Reflect App BT - (Self-)confident through the introductory study phase with the Reflect App T2 - CEUR Workshop Proceedings T2 - Selbst-bewusst durch die Studieneingangsphase mit der Reflect-App Y1 - 2014 UR - http://www.scopus.com/inward/record.url?eid=2-s2.0-84921875162&partnerID=MN8TOARS SN - 1613-0073 IS - 1227 SP - 172 EP - 179 PB - CEUR-WS CY - Freiburg ER - TY - CHAP T1 - 11.

A1 - Tompits, Hans A1 - Wang, Kewen T1 - A classification and survey of preference handling approchaches in nonmonotonic reasoning N2 - In recent years, there has been a large amount of disparate work concerning the representation and reasoning with qualitative preferential information by means of approaches to nonmonotonic reasoning. Given the variety of underlying systems, assumptions, motivations, and intuitions, it is difficult to compare or relate one approach with another. Here, we present an overview and classification for approaches to dealing with preference. A set of criteria for classifying approaches is given, followed by a set of desiderata that an approach might be expected to satisfy. A comprehensive set of approaches is subsequently given and classified with respect to these sets of underlying principles Y1 - 2004 SN - 0824-7935 ER - TY - JOUR A1 - Wang, Kewen T1 - A comparative study of disjunctive well-founded semantics Y1 - 2001 SN - 3-540-42593-4 ER - TY - JOUR A1 - Schaub, Torsten H.
