This study examines the factors affecting the propensity of firms to engage in cross border activities in a world of increasing returns. A model connecting outward FDI from the US with a set of firm-specific advantages is estimated on samples of industries dominated by increasing and diminishing return processes. Wymbs and Luisa Corrado on earlier drafts are gratefully acknowledged.

This paper aims at empirically exploring the relationships between existing object-oriented coupling, cohesion, and inheritance measures and the probability of fault detection in system classes during testing. The underlying goal of such a study is to better understand the relationship between existing design measurement in OO systems and the quality of the software developed. Results show that...

This paper describes the use of conditioned slicing to assist partition testing, illustrating this with a case study. The paper shows how a conditioned slicing tool can be used to provide confidence in the uniformity hypothesis for correct programs, to aid fault detection in incorrect programs and to highlight special cases.

Most observer-based methods applied in fault detection and diagnosis (FDD) schemes use the classical twodegrees of freedom observer structure in which a constant matrix is used to stabilize the error dynamics while a post filter helps to achieve some desired properties for the residual signal. In this paper, we consider the use of a more general framework which is the dynamic observer structure...

This paper deals with fault detection and more particularly with the Fundamental Problem of Residual Generation (FPRG). In former works, conditions, based on the properties of invariant distributions involving the disturbance vector field, were given to solve this problem. The aim of the present paper is to provide, when those conditions are not fulfilled, an alternative solution to the FPRG, b...
