Hiring Practices, Employment Protection and Temporary Jobs

This paper examines the effects of a two-tier reform of the Employment Protection Legislation that increases flexibility at the margin by allowing firms to hire workers on temporary positions and investigates under which conditions temporary jobs are stepping stones to permanent employment. The analysis has far focused on the role of temporary jobs in employers adjustment to economic shocks and...

Temporary Protection and Technology Choice under the Learning Curve

This paper examines the effects of temporary protection in a model of international Cournot competition under the learning curve. We show that when the protected firm can choose among multiple technologies subject to different scopes for learning, the positive relationship between current production and learning cannot be relied upon. The protection may hurt the long-run competitiveness of the ...

RaceGuard: Kernel Protection From Temporary File Race Vulnerabilities

Temporary file race vulnerabilities occur when privileged programs attempt to create temporary files in an unsafe manner. “Unsafe” means “non-atomic with respect to an attacker’s activities.” There is no portable standard for safely (atomically) creating temporary files, and many operating systems have no safe temporary file creation at all. As a result, many programs continue to use unsafe mea...

Modelling the effects of temporary immune protection and vaccination against infectious diseases

In this paper, we develop a mathematical model to describe the dynamics of reinfection under the assumption that immune protection may wane over time. As a disease control strategy a schedule of primary and secondary (booster) vaccination is studied, with vaccine induced immunity declining over time. A distinction is made between infection in immunological naive individuals (primary infection) ...
