What's mine is yours. An increasing number of people are participating in sharing and exchanging information, knowledge, data and goods. As research addressing the so‐called ‘sharing economy’ is still in its infancy, this article aims to shed light on it. To do this, a qualitative research approach comprising guided interviews with 14 companies from Germany, Austria and Switzerland provides detailed insights into different aspects of the sharing economy phenomenon. Our results make a direct contribution to sharing economy research, especially regarding the new business models of start‐ups. Here, we find a clear difference between the relevance of economic and social orientation. The latter appears to be in higher demand among customers than entrepreneurs. The increasingly digitalized environment has led to a changed living situation characterized by urbanity, openness to new solutions, changed working situations and new mindsets. All of these aspects drive the sharing economy. The results of this paper are summarized in a framework highlighting the requirements, drivers and goals of the sharing economy. Considering the limited research in this field, the developed framework is a strong basis for discussion, critique and/or support of future research.

JEL classification: M13 O3 O31 O320 Keywords: Crowdfunding Reward-based Success factors Germany fsQCA Communication a b s t r a c t Crowdfunding represents an alternative way of funding entrepreneurial ventures -and is attracting a high amount of interest in research as well as practice. Against this background, this paper analyzes reward-based crowdfunding campaign strategies and their communication tools. To do this, 446 crowdfunding projects were gathered and empirically analyzed. Three different paths of successful crowdfunding projects could be identified and are described in detail. Practical implications of crowdfunding strategies are derived, and are dependent on the required sales effort and the project added value. The terms communicator, networker and self-runner are created for this crowdfunding strategy and filled with practical examples. This paper contributes to the literature in different ways: first, it sheds more light on the developing concept of crowdfunding, with an overview of current academic discussions on crowdfunding. Furthermore, the analysis of success factors for crowdfunding initiatives adds to an emerging area of research and allows entrepreneurs to extract best practice examples for increasing the probability of successful crowdfunding projects under consideration of the key influencing factors of communication.

Peak accelerations as measured at the surface of the head were 160 to 180% greater from heading a soccer ball than from routine (noninjurious) impacts during hockey or football, respectively. The effect of cumulative impacts at this level may lead to neurologic sequelae.

Findings highlighted biomechanical differences between limbs which are consistent across jump tasks suggesting insufficient rehabilitation at 9 months post surgery. Results indicate that the SLDJ may identify greater performance deficits between limbs than SLHD, which may over-estimate rehabilitation status.
