of Liver Diseases. The original guidelines were published in HEPATOLOGY 2001;34:1225–1241.1 In light of recent progress, particu-larly in the treatment of chronic hepatitis B, these guidelines were updated in September of 2003. A complete version of the updated guidelines, including a review of recently

Impairments in motor functioning, which, until recently, have rarely been a primary focus in autism spectrum disorder (ASD) research, may play a key role in the early expression of bio-logical vulnerability and be associated with key social-communication deficits. This review summarizes current

Manifestation of hormesis in longevity was modelled by modification of the mortality rate during and after the period of a stress factor action. In heterogeneous population this can lead to observation of unchanged mortality during action of the stress and decrease in mortality after stress period. Stochastic simulations were made to investigate the possibility of detecting the hormesis effect on the basis of the stress-control longitudinal data. The goal of the stochastic simulation was to investigate the role in the hormesis detection of control and stressed group size, of population heterogeneity variance value, of stress and hormesis attributable risks as well as the role of a prior information about the survival in the control group. It was demonstrated that if the attributable risks for stress and hormesis effects are approximately equal, then in both ‘high ’ and ‘low ’ heterogeneous populations the hormesis phenomenon is detected with probability higher than 75 % even in relatively ‘small ’ groups of 50 subjects. In case of ‘weak ’ effect the hormesis phenomenon is not detected in a ‘highly heterogeneous ’ population even in a group composed of 1000 subjects. In a ‘low heterogeneous ’ population the hormesis phenomenon is detected with probability higher than 70 % when the group size is not less than 200 subjects. Information about the survival in control

From time to time we hope to publish bibliographical articles. These will sometimes draw attention to important contributions to recent study which are sometimes over-looked. Dr. Guthrie, Lecturer in New Testament at London Bible College, is well-known for his work on the Pastoral Epistles. He

... This paper provides an up-to-date critical survey of still- and video-based face recognition research. There are two underlying motivations for us to write this survey paper: the first is to provide an up-to-date review of the existing literature, and the second is to offer some insights

We review the literature on semi-supervised learning, which is an area in machine learning and more generally, artificial intelligence. There has been a whole spectrum of interesting ideas on how to learn from both labeled and unlabeled data, i.e. semi-supervised learning. This document is a

This paper provides an elementary, non-technical, survey of auction theory, by introducing and describing some of the critical papers in the subject. (The most important of these are reproduced in a companion book, The Economic Theory of Auctions, Paul Klemperer (ed.), Edward Elgar (pub.), forthcoming.) We begin with the most fundamental concepts, and then introduce the basic analysis of optimal auctions, the revenue equivalence theorem, and marginal revenues. Subsequent sections address risk-aversion, affiliation, asymmetries, entry, collusion, multi-unit auctions, double auctions, royalties, incentive contracts, and other topics. Appendices contain technical details, some simple worked examples, and a bibliography for each section.

Recent empirical and case study evidence documents a strong association between the adoption of computers and increased use of college educated or non-production workers. With few exceptions, the conceptual link explaining how computer technology complements skilled labor or substitutes
