This paper presents the design of TOBIT, an infrastructure to support Web-based simulations. TOBIT provides a subnet grid, which is partitioned into web server tier, database server tier and simulation server tier. This grid is self-managed through the simulation manager (SimMan) extended from the Oracle Grid Control [3]. TOBIT is currently being used to support autonomic computing of two web-b...

Over recent years, interest has been growing in Bitcoin, an innovation which has the potential to play an important role in e-commerce and beyond. The aim of our paper is to provide a comprehensive empirical study of the payment and investment features of Bitcoin and their implications for the conduct of ecommerce. Since network externality theory suggests that the value of a network and its ta...

I study a simple, widely applicable approach to handling the initial conditions problem in dynamic, nonlinear unobserved effects models. Rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables, I propose finding the distribution conditional on the initial value (and the observed history of strictly exogenous explanatory variables). The approach is fle...

Truncated and censored regression models are useful when the dependent variable is observed in some ranges but not in others. A classical example is Tobin’s (1958) study of household expenditures, in which expenditures on durable goods were seen to generally increase with income, but a non-trivial number of households had no expenditures on durable goods. The problem, in this case, is how to mo...

Students between 12 and 19 years participated in an online study. They reported on the frequency of different traditional and cyberbullying behaviours and completed self-report measures on moral emotions and moral values. A scenario approach w...
