Time Zones and FDI with Heterogeneous Firms
Based on Helpman et al. (2004) we propose a simple two-country (Home and Foreign) model with heterogeneous firms to capture the role of FDI via utilizing time zone differences. Two countries are located in different time zones and there is no overlap in daily working hours. It will be shown that productivities of the firms undertaking FDI are higher than the productivities of non-FDI f i r m s ...
متن کاملModeling Botnet Propagation Using Time Zones
Time zones play an important and unexplored role in malware epidemics. To understand how time and location affect malware spread dynamics, we studied botnets, or large coordinated collections of victim machines (zombies) controlled by attackers. Over a six month period we observed dozens of botnets representing millions of victims. We noted diurnal properties in botnet activity, which we suspec...
متن کاملReal-time Plume Detection in Urban Zones Using Networked Sensing
The release of a chemical/biological/nuclear (C/B/N) agent in a city remains a viable threat. As these silent, invisible and odorless plumes can cause massive casualties that would overwhelm emergency facilities, modeling, tracking and real-time prediction of plume dispersion and lethality is central to developing a user-friendly first responder's tool for evacuating civilians and managing emer...
متن کاملDeveloping Software Across Time Zones: An Exploratory Empirical Study
Market forces and an increasingly reliable world-wide communications network have made geographically distributed software engineering a reality. Global software development enables businesses to respond more easily and more quickly to global market opportunities and to improve product and service quality. One of the many potential benefits of global development is a reduction in development ti...
متن کاملCircadian Biology: An Unexpected Invitee to New Time Zones
Adaptation to changing light conditions is a hallmark of the circadian clock. A new study points to the critical role played by a transcriptional repressor previously implicated in cell differentiation, highlighting unappreciated links between the clock and the control of development and tumorigenesis.
