That tax haven policies contribute to favorable economic growth in tax haven countries is commonly accepted. There is, however, minimal empirical evidence to substantiate this assertation and empirical investigations are subject to endogeneity bias. Using a sample of 155 countries from 1982 to 2003, we find that the standard tax haven variable is endogenous to the error term in a typical growth...

The specific pathways through which close relationships promote optimal well-being are not well understood. We describe a model (building on attachment theory's notion of safe haven and secure base support) that explains how close relationships promote thriving. This model defines thriving, identifies distinct contexts through which individuals may thrive (life adversity and life opportunities ...

Graphics processing unit (GPU), although a powerful performance-booster, also has many security vulnerabilities. Due to these, the GPU can act as a safe-haven for stealthy malware and the weakest ‘link’ in the security ‘chain’. In this paper, we present a survey of techniques for analyzing and improving GPU security. We classify the works on key attributes to highlight their similarities and di...
