Despite the large volume of information sharing across digital platforms, no study has systematically investigated how firms can monetize such sharing traffic. Our study examines whether and how firms can engage customers involved in online sharing, through the design of novel incentive mechanisms. We design and implement a large-scale randomized field experiment to test the effectiveness of di...

PURPOSE To investigate the correlation between the retinal vascular fractal dimension (Fd) and neurodegenerative changes in patients with no or mild diabetic retinopathy (DR). METHODS In this cross-sectional study we examined 103 patients with type 2 diabetes mellitus (T2DM) with no or mild DR. In a randomly selected eye of each patient, Fd was calculated using SIVA-Fractal, a specialized sem...

We study the online market for peer to peer (P2P) lending in which individuals bid on unsecured microloans sought by other individual borrowers. Using a large sample of consummated and failed listings from the largest online P2P lending marketplace Prosper.com, we test whether social networks lead to better lending outcomes, focusing on the distinction between the structural and relational aspe...

This paper presents SIRENA, a CAD environment for the simulation and modeling of mixed-signal VLSI parallel processing chips based on Cellular Neural Networks. SIRENA includes capabilities for: a) the description of nominal and non-ideal operation of CNN analog circuitry at the behavioral level; b) performing realistic simulations of the transient evolution of physical CNNs including deviations...

This is dedicated to my family and everyone else who helped me along my way just so they could see me succeed. This is also dedicated to the innocent students and faculty who lost their lives at Virginia Tech on April 16, 2007 doing what I am doing now: pursuing a higher education. iv ACKNOWLEDGEMENTS I would like to thank Dr. Ali Adibi for being my advisor, for always being accommodating and w...

ii ACKNOWLEDGEMENTS I would like to take this opportunity to thank each and everyone who helped me to achieve my Master's degree. First and foremost, I would like to dedicate my work to the God I believe Sri Venkateswara swamy and my parents, Venkaiah Thulluri and Koteswaramma Thulluri for what I am today. They have given me strength day after day. If it were not for them, I would not have made...

Der Einsatz von Videos in E-Learning-Applikationen wird zunehmend forciert. Die Interaktivität in diesen Applikationen ist dabei jedoch meist sehr gering. Sie beschränkt sich im Allgemeinen auf das Unterbrechen und das Springen in die nächste Szene des Videos, wodurch ein exploratives, situiertes und problemorientiertes Lernen kaum möglich ist. Mit Hilfe einer integrierten Lösung für die Produk...

We study whether and how a firm can enhance social contagion by simply varying the message shared by customers with their friends. We focus on two key components of information contained in the messages – information about sender’s purchase status prior to referral, and information about the existence of referral rewards – and their impacts on the recipient’s purchase decision and further refer...
