Understanding a central bank’s operating procedures is important for two reasons. First, it is important in empirical work to distinguish between endogenous responses to developments in the economy and exogenous shifts in policy. Whether movements in a monetary aggregate or a short-term interest rate are predominantly endogenous responses to disturbances unrelated to policy shifts or are exogen...

Motivated by the problems encountered in the operation of the front end of a grocery store, a queuing model is formulated for a variable channel queuing system. A cost structure is superimposed over the queuing model and after examining the customer jockeying properties of the system, an optimal operating policy is generated. The practical aspects of the generation and implementation of an opti...

The following paper should give an overview about the state of the art of features, concepts and challenges of mobile operating systems to integrate them into an enterprise environment.

We present an approach that addresses the problem of securing software configurations from the security-relevant actions of poorly built/faulty installation packages. Our approach is based on a policy-based control of the package manager’s actions and is customizable for site-specific policies. We discuss an implementation of this approach in the context of the Linux operating system for the Re...

Flexibility and user-customizability are amongst the potential beneets of reorganizing and restructuring operating systems using object-orientation. However, operating systems are often designed as black boxes whose internals cannot easily be examined or tailored by the user or application. As a black box, the complexity of an operating system appears to grow as additional features and options ...

The formulation of global health policy is political; and all institutions operating in the global health landscape are political. This is because policies and institutions inevitably represent certain values, reflect particular ideologies, and preferentially serve some interests over others. This may be expressed explicitly and consciously; or implicitly and unconsciously. But it’s important t...

We develop a model for two-sided markets with consumers and producers, who interact through a platform. Typical settings for the model are the market for smartphones with phone users, app producers, and smartphone operating systems; or the video game market with game players, video game producers, and video game consoles. Only consumers who purchase the platform can access content from the prod...
