D of physics from Moscow Institute of Physics and Technology, Russia in 1997 and Stanford University, USA in 2001. He conducted his post-doctoral research at Stanford University, University of Delaware and Texas A&M University from 2001-2007. Dr. Svidzinsky has a variety of broad interests including Quantum optics, Bose-Einsten condensation, Superconductivity, Chemical physics and Astrophysics. He is a Fellow of the American Optical Society (2018) and has 110 publications with citation over 3500 and H-index 32.Abstract:The observation of gravitational waves by the three LIGO-Virgo interferometers allows the examination of the polarization of gravitational waves. We analyze the binary neutron star event GW170817, whose source location and distance are determined precisely by concurrent electromagnetic observations. Applying a signal accumulation procedure to the LIGO-Virgo strain data, we find ratios of the signals detected by the three interferometers. We conclude that the signal ratios are inconsistent with the predictions of general relativity, but consistent with the recently proposed vector theory of gravity [1,2]. Moreover, we find that vector gravity yields a distance to the source in agreement with the astronomical observations. If our analysis [3,4] is correct, Einstein’s general theory of relativity is ruled out in favor of vector gravity and future gravitational wave detections by three or more observatories should confirm this conclusion with higher precision.

Despite the popularity, the effects of personal training app on improving fitness remains largely mixed. Extending the activity theory to the context of personal training app usage and integrating it with the self-quantification and self-presentation literature, we examine two popular app features, namely activity tracking and social sharing on fitness improvement over time. We also posit that the effects of these features on fitness improvement will interact with in-app achievement frequency, which is expected to reduce over time. To operationalize the study, we conducted a field experiment involving 647 subjects and observed their app usage as well as captured their fitness levels over an 18-month period. Results reveal that personal training app is generally helpful to improving fitness and social sharing enables greater fitness improvement compared with activity tracking. Furthermore, we found that in-app achievement frequency declines over time and this decline diminishes the effects of personal training app on fitness improvement in the long run. We discuss how these findings contribute to the self-quantification literature in information systems and self-presentation research in the human-computer interaction field. We also discuss implications for practice and provide suggestions for future works.

Venue: Room 1102, Library & Information Building C, Zijingang CampusSpeaker: Qing Wang, Professor of Marketing and Innovation, Warwick Business SchoolAbstract:Effectuation plays an important role in decision-making and actions of new ventures, but there are still many inconsistencies in the theoretical understanding of its relationship between entrepreneurial performance. Applying the ambidexterity theory, market ambidexterity in new ventures is used as a mediator variable to explore the logical relationship between effectuation and entrepreneurial performance in the market level. Using data from 186 new enterprises, the empirical analysis shows that effectuation has a significant impact on the balance and interplay between market exploration and market exploitation, and its impact mechanism is different; effectuation also has positive effects on operating performance and growth performance; the balance of market ambidexterity has positive influence on operating performance, while the interplay of market ambidexterity has a significant effect on growth performance. The research conclusions provide several management implications for new ventures to apply effectuation to achieve market ambidexterity and improve entrepreneurial performance.
