Item Bending the Rules or Changing Them? MNE Responses to Institutional Challenges in Transition Economies(Sage Publications Ltd, 2019-04-16) Yu, J.; Lee, Seung-Hyun; Lee, Seung-HyunWe investigate what determines a multinational enterprise’s (MNE) propensity to engage in lobbying and bribing in host countries where the overall institutional development for market exchanges is insufficient, and thus, their governance systems are relatively weak. We extend the current literature on institutional strategies by theorizing and showing the persistent and significant impacts of home country institutions on an MNE’s choice of influencing activities to address institutional constraints overseas. More specifically, our results demonstrate that the MNEs from a home country with a stronger governance system are less involved in bribery, but have a higher tendency to lobby in transition economy countries, which have been characterized by relatively weaker institutional development, particularly in the area of governance. This tendency still holds even when these MNEs rely more on the local market for sales. We draw theoretical and practical implications from these observations. © The Author(s) 2019.Item Propagation Characteristics of Plasmaspheric Hiss: Van Allen Probe Observations and Global Empirical Models(Amer Geophysical Union, 2017-03-13) Yu, J.; Li, L. Y.; Cao, J. B.; Chen, Lunjin; Wang, J.; Yang, J.; 0000-0003-2489-3571 (Chen, L); Chen, LunjinBased on the Van Allen Probe A observations from 1 October 2012 to 31 December 2014, we develop two empirical models to respectively describe the hiss wave normal angle (WNA) and amplitude variations in the Earth's plasmasphere for different substorm activities. The long-term observations indicate that the plasmaspheric hiss amplitudes on the dayside increase when substorm activity is enhanced (AE index increases), and the dayside hiss amplitudes are greater than the nightside. However, the propagation angles (WNAs) of hiss waves in most regions do not depend strongly on substorm activity, except for the intense substorm-induced increase in WNAs in the nightside low L-region. The propagation angles of plasmaspheric hiss increase with increasing magnetic latitude or decreasing radial distance (L-value). The global hiss WNAs (the power-weighted averages in each grid) and amplitudes (medians) can be well reproduced by our empirical models.
