Measuring productive efficiency for nonprofit organizations has posed a great challenge to applied researchers today. The problem has many facets and diverse implications for a number of disciplines such as economics, applied statistics, management science and information theory. This monograph discusses four major areas, which emphasize the applied economic and econometric as. pects of the production frontier analysis: A. Stochastic frontier theory, B. Data envelopment analysis, C. Clustering and estimation theory, D. Economic and managerial applications Besides containing an up-to-date...

This volume in the series Developments in Medical Virology deals with viruses involved in diabetes mellitus, a syndrome with a strong genetic background that causes damage to the regulation of insulin synthesis and function. Viruses were found either to cause or to stimulate diabetes mellitus in man and in animal models. The nature of the role of viruses is described by many of the scientists who participated in the original studies. To complete the picture, chapters were included that deal with the insulin gene, the secondary structure of the proinsulin and insulin receptor polypeptides,...

In the summer of 1984, both of us were working with Professor Yechiel Becker in the Laboratory for Molecular Virology at the Hebrew University-Hadassah Medical center in Jerusalem. During a discussion about the increasing number of specialized journals and monographs, Dr. Becker pointed out that none covered both the clinical and molecular aspects of neurotropic virus infections, and he urged us to develop such a book with the help of colleagues who were conducting highly-regarded research in their individual areas related to neurotropic viruses. The responses to our request were gratifying,...

Antiviral chemotherapy has come of age, and, after an initial slow pro gress, the development of new antiviral agents has proceeded at a more rapid pace and the perspectives for their clinical use have increased considerably. Now, 25 years after the first antiviral assay (idoxuridine) was introduced in the clinic, it is fitting to commemorate the beginning of the antivirals' era. In its introductory chapter B.E. Juel-Jensen touches on what may be con sidered as five of the most fundamental requirements of an antiviral drug: efficacy, relative non-toxicity, easy solubility, ready availability...

Shortly after the reeognition of the aequired immunodefieieney syndrome (AIDS) in 1981 (1-3), it was hypothesized that herpesviruses may play an important role in the etiology or pathogenesis of this newly identified syndrome (4,5). This theory was based on the faet that infeetion with herpesviruses was a prominent elinieal feature in nearly all patients with AIDS (3-5). Chronie mueocutaneous herpes simplex virus (HSV) infections were one of the first opportunistie infeetions deseribed in patients with AIDS (3), and both cytomegalovirus (CMV) and HSV infections were extremely common in...
