Beyond Barrows
Europe is dotted with tens of thousands of prehistoric barrows. In spite of their ubiquity, little is known on the role they had in pre- and protohistoric landscapes. In 2010, an international group of archaeologists came together at the conference of the European Association of Archaeologists in The Hague to discuss and review current research on this topic. This book presents the proceedings of that session. The focus is on the prehistory of Scandinavia and the Low Countries, but also includes an excursion to huge prehistoric mounds in the southeast of North America. One contribution presents new evidence on how the immediate environment of Neolithic Funnel Beaker (TRB) culture megaliths was ordered, another one discusses the role of remarkable single and double post alignments around Bronze and Iron Age burial mounds. Zooming out, several chapters deal with the place of barrows in the broader landscape. The significance of humanly-managed heath in relation to barrow groups is discussed, and one contribution emphasizes how barrow orderings not only reflect spatial organization, but are also important as conceptual anchors structuring prehistoric perception. Other authors, dealing with Early Neolithic persistent places and with Late Bronze Age/Early Iron Age urnfields, argue that we should also look beyond monumentality in order to understand long-term use of "ritual landscapes". The book contains an important contribution by the well-known Swedish archaeologist Tore Artelius on how Bronze Age barrows were structurally re-used by pre-Christian Vikings. This is his last article, written briefly before his death. This book is dedicated to his memory. This publication is part of the Ancestral Mounds Research Project of the University of Leiden.
Quality of Experience Engineering for Customer Added Value Services

The main objective of the book is to present state-of-the-art research results and experience reports in the area of quality monitoring for customer experience management, addressing topics which are currently important, such as service-aware future Internet architecture for Quality of Experience (QoE) management on multimedia applications. In recent years, multimedia applications and services have experienced a sudden growth. Today, video display is not limited to the traditional areas of movies and television on TV sets, but these applications are accessed in different environments, with different devices and under different conditions. In addition, the continuous emergence of new services, along with increasing competition, is forcing network operators and service providers to focus all their efforts on customer satisfaction, although determining the QoE is not a trivial task. This book addresses the QoE for improving customer perception when using added value services offered by service providers, from evaluation to monitoring and other management processes.
The Two Sides of Perception
Anatomically, the central nervous system looks remarkably symmetrical--from the relatively simple structures of the spinal cord to the extensively convoluted folds of the cerebral hemispheres. At the functional level, however, there are striking differences between the left and right hemispheres. Although popular writings attribute language abilities to the left hemisphere and spatial abilities to the right, differences in hemispheric function appear to be more subtle. According to Ivry and Robertson, asymmetries over a wide range of perceptual tasks reflect a difference in strength rather than kind, with both hemispheres contributing to the performance of complex tasks, whether linguistic or spatial. After an historical introduction, the authors offer a cognitive neuroscience perspective on hemispheric specialization in perception. They propose that the two hemispheres differ in how they filter task-relevant sensory information. Building on the idea that the hemispheres construct asymmetric representations, the hypothesis provides a novel account of many laterality effects. A notable feature of the authors' work is their attempt to incorporate hemispheric specialization in vision, audition, music, and language within a common framework. In support of their theory, they review studies involving both healthy and neurologically impaired individuals. They also provide a series of simulations to demonstrate the underlying computational principles of their theory. Their work thus describes both the cognitive and neurological architecture of hemispheric asymmetries in perception.
