Published results on the use of the kappa coefficient of agreement have traditionally been concerned with situations where a large number of subjects is classified by a small group of raters. The coefficient is then used to assess the degree of agreement among the raters through hypothesis testing or confidence intervals. A modified kappa coefficient of(More)
In a recent paper Maritz and Jarrett (1978) proposed a small-sample estimate of the variance of sample medians from continuous population. In this paper their methods are adapted to median estimation in s~atified sampling without replacement from finite populations. A weighted sample median for estimating the median of heavy-tailed or skewed populations is(More)
We suggest that the proximity of a country to other countries is a factor that affects its choice as an MNE location. We introduce the concept of a country's proximity to the global distribution of knowledge, markets and resources, and frame this concept as a function of both geographic distance and the worldwide spatial distribution of these factors. We(More)
This short paper resolves an apparent contradiction between Feldman's (1989) and Riedel's (2000) equilibrium models of the term structure of interest rates under incomplete information. Feldman (1989) showed that in an incomplete information version of Cox, Ingersoll, and Ross (1985), where the stochastic productivity factors are unobservable, equilibrium(More)

The Paul-Ehrlich Institute (PEI) is an independent institution of the Federal Republic of Germany responsible for performing official experimental batch testing of sera. The institute decides about the release of each batch and performs experimental research in the field. The experimental quality control ensures the potency of the product and also the(More)
An international collaborative study to validate 2 alternative in vitro methods for the potency testing of human tetanus immunoglobulin products was organised by the European Directorate for the Quality of Medicines & HealthCare (EDQM). The study, run in the framework of the Biological Standardisation Programme (BSP) under the aegis of the European(More)
The European Pharmacopoeia (Ph. Eur.) monograph Human tetanus immunoglobulin (0398) gives a clear outline of the in vivo assay to be performed to determine the potency of human tetanus immunoglobulins during their development. Furthermore, it states that an in vitro method shall be validated for the potency estimation. Since no further guidance is given on(More)
