Who do you trust: Peers or Technology? A conjoint analysis about computational reputation mechanisms
(2020)
Peer-to-peer sharing platforms are taking over an increasingly important role in the platform economy due to their sustainable business model. By sharing private goods and services, the challenge arises to build trust between peers online mostly without any kind of physical presence. Peer rating has been proven as an important mechanism. In this paper, we explore the concept called Trust Score, a computational rating mechanism adopted from car telematics, which can play a similar role in carsharing. For this purpose, we conducted a conjoint analysis where 77 car owners chose between fictitious user profiles. Our results show that in our experiment the telemetric-based score slightly outperforms the peer rating in the decision process, while the participants perceived the peer rating more helpful in retrospect. Further, we discuss potential benefits with regard to existing shortcomings of user rating, but also various concerns that should be considered in concepts like telemetric-based reputation mechanism that supplements existing trust factors such as user ratings.
This article explores the opportunities, challenges, as well as the activities of the Chinese governmental and commercial stakeholders to promote cross-border e-commerce trade between China and Africa, based on the classification and correlation analysis of the literature from 2011 to 2019. The results show that the biggest driver for the development of China-Africa cross-border e-commerce trade is the gap between the rapid growth of the African population, especially the middle class, and the limited local capability to satisfy their demand. The rapid development of the internet and mobile internet is another driving factor. The biggest challenge is the last mile delivery of logistics, and online payment issues in Africa. At the macro-level the Chinese government has promoted measures such as infrastructure investment, e-commerce test zones and the establishment of pilot projects. At the firm level, Chinese companies have focused on solving practical micro-level local operational problems such as logistics, online payment, and talent training. The results also show that the referred literature is still in its infancy, mostly theoretical and less practical, and requires more in-depth domain specific analysis in the future.
Zur Beschreibung der Prävalenzen des für Deutschland relevanten Glücks- und Gewinnspiels finanziert der Bund u. a. den Forschungsbericht der Bundeszentrale für gesundheitliche Aufklärung (BZgA) „Glücksspielverhalten und Glücksspielsucht in Deutschland“, der alle zwei Jahre veröffentlicht wird.(1) Die BZgA ist eine Fachbehörde im Geschäftsbereich des Bundesministeriums für Gesundheit (BMG). Zudem fördert das BMG aufgrund eines Beschlusses des Deutschen Bundestages den vom IFT Institut für Therapieforschung (IFT), eine gemeinnützige Gesellschaft mit beschränkter Haftung (gGmbH), jährlich herausgegebenen Jahresbericht der Deutschen Suchthilfestatistik (DSHS)(2) mit dem Titel Suchthilfe in Deutschland.3 Die dort veröffentlichten Ergebnisse fassen jeweils die aktuellen Ergebnisse der DSHS zusammen.
