How Social Reputation Networks Interact with Competition in Anonymous Online Trading: An Experimental Study

Many Internet markets rely on ‘feedback systems’, essentially social networks of reputation, to facilitate trust and trustworthiness in anonymous transactions. Market competition creates incentives that arguably may enhance or curb the effectiveness of these systems. We investigate how different forms of market competition and social reputation networks interact in a series of laboratory online markets, where sellers face a moral hazard. We find that competition in strangers networks (where market encounters are one-shot) most frequently enhances trust and trustworthiness, and always increases total gains-from-trade. One reason is that information about reputation trumps pricing in the sense that traders usually do not conduct business with someone having a bad reputation not even for a substantial price discount. We also find that a reliable reputation network can largely reduce the advantage of partners networks (where a buyer and a seller can maintain repeated exchange with each other) in promoting trust and trustworthiness if the market is sufficiently competitive. We conclude that, overall, competitive online markets have more effective social reputation networks.reputation systems, e-commerce, internet markets, trust

Community on the watch: making sense of is research through the lens of espoused theories of is

Community on the Watch: Making Sense of IS Research through the Lens of Espoused Theories of IS In the IS field there has been an ongoing tradition to study the publication output of the community in order to evaluate the current and potential situation of IS research. In this work, we follow a different strategy and study what IS research claims to be. We look at those so-called 'espoused theories of IS' as found in the General Editorials Statements (GES) of IS journals. Based on the AISWorld journal ranking, we collected GES for 30 leading IS journals for the years 1997 and 2007. We applied thematic, lexicometric, and factor analyses to the datasets of the 1997 and the 2007 GES. Our results show that the representation of IS research in the GES has changed little over the last decade.: Espoused Theory, Information Systems (IS), Research, Expectations, General Editorial Statement (GES), IS Journals, Thematic Analysis, Lexicometric Analysis.

Size does matter: The use of fish motion for improving human swimming simulations

In this study we evaluated the length and volume inconsistencies that occur when applying simple motion functions onto surface models of swimming fish and human, respectively. The larger the size (diameter and length) of the body, the larger are these inconsistencies. To eliminate these errors, different surface correction algorithms are introduced. Additional terms are implemented to overcome structural insufficiencies through over-stretching and overlapping in sensible body parts. For human undulatory swimming these models combine the motion of rigid extremities with the smooth surface bending at joints. The advantages of this hybrid model can be crucial for Computational Fluid Dynamics, where deviation from natural behaviour results in unrealistic surface pressures and artificial vortex structures. The structural improvements are also promising for computational graphic programming, where skin-like stretching surfaces mediate a natural impression

Digital Video Recorder Driven Impacts on the Video Content Services Industry

Being part of a larger research program, this paper focuses on the impacts of so-called \u27Digital Video Recorders\u27 (DVRs) on the video content services industry. First, it gives a succinct definition of the video content services industry using the value chain as a metaphor. After laying a brief theoretical foundation on technological change and adoption, it considers the technological factors \u27increased broadband connectivity to the home\u27 and \u27increased storage capacities\u27 as change drivers in the video content services industry. The paper then highlights DVRs in detail (features, history, evolution, and viewer behavior) and investigates implications of a DVR roll-out for the different value propositions of players in the industry. It concludes with a brief outlook for the industry in the light of new technological developments
