New Electricity Technologies for a Sustainable Future

There is a growing concern over our reliance on conventional electricity sources and their long-term environmental, climate change, and security of supply implications, and much hope is vested in the ability of future technological progress to tackle these issues. However, informed academic analysis and policy debates on the future of electricity systems must be based on the current state, and prospects of, technological options. This paper is the introductory chapter in the forthcoming book Future Electricity Technologies and Systems. The book comprises contributions from leading experts in their respective technology areas. The chapters present state of the art and likely progress paths of conventional and new electricity generation, networks, storage, and end-use technologies. In this paper we review the growth trend in electricity demand and carbon emissions. We then present a concise overview of the chapters. Finally, we discuss the main contextual factors that influence long-term technological progress

Impact perforation testing of stab-resistant armour materials

This paper describes the development of a method for the investigation and comparison of materials for use in stab resistant body armour. A number of polymer composite panels of different thicknesses and construction have been tested. A dynamic test which simulated the real threat has been used and the results compared to a simpler quasi-static test that might be used in initial materials selection. The materials tested were glass-epoxy, and glass-nylon composite panels of several thicknesses between 1.8 and 5.8mm. Additional tests were also performed on similar composites containing tungsten wires. An accelerated instrumented drop-tower was used to drive a knife through composite panels and record the force resisting penetration by the knife. The final penetration of the knife through the armour into a soft backing was also measured. For comparison,a similar geometry quasi-static test was carried out on the same specimens. It was found that energy absorbtion took the form of an initial resistance to perforation and then by a resistance to further penetration. This is thought to stem from resistance to cutting ofthe panel material and gripping of the knife blade. The energy required to produce a given penetration in dynamic tests was found to be in good agreement with the penetration achieved at similar energies under quasi-static conditions. For the materials tested there was no significant difference between the penetration resistance of single or two layer systems. The penetration achieved through a panel of a given material was approximately proportional to the inverse square of the panel's thickness. The relative performance of different armour materials was assessed by plotting the energy required to penetrate a fixed distance against the areal density of the panel

Project Retrosight. Understanding the returns from cardiovascular and stroke research: Case Studies

Copyright @ 2011 RAND Europe. All rights reserved. The full text article is available via the link below.This project explores the impacts arising from cardiovascular and stroke research funded 15-20 years ago and attempts to draw out aspects of the research, researcher or environment that are associated with high or low impact. The project is a case study-based review of 29 cardiovascular and stroke research grants, funded in Australia, Canada and UK between 1989 and 1993. The case studies focused on the individual grants but considered the development of the investigators and ideas involved in the research projects from initiation to the present day. Grants were selected through a stratified random selection approach that aimed to include both high- and low-impact grants. The key messages are as follows: 1) The cases reveal that a large and diverse range of impacts arose from the 29 grants studied. 2) There are variations between the impacts derived from basic biomedical and clinical research. 3) There is no correlation between knowledge production and wider impacts 4) The majority of economic impacts identified come from a minority of projects. 5) We identified factors that appear to be associated with high and low impact. This report presents the key observations of the study and an overview of the methods involved. It has been written for funders of biomedical and health research and health services, health researchers, and policy makers in those fields. It will also be of interest to those involved in research and impact evaluation.This study was initiated with internal funding from RAND Europe and HERG, with continuing funding from the UK National Institute for Health Research, the Canadian Institutes of Health Research, the Heart and Stroke Foundation of Canada and the National Heart Foundation of Australia.

How do Multinationals Build Social Capital? Diageo's Corporate Citizenship Programme.

This paper attempts to enhance understanding of the process by which multinationals build social capital by examining the Corporate Citizenship (CC) activities and associated social capital outcomes of the UK-based branded alcoholic drinks company, Diageo. The firm possesses a structured portfolio of CC initiatives and projects and has a long-standing tradition of community engagement. This paper examines Diageo’s CC strategy in depth and considers the ways that their engagements impact upon social capital development in different arenas. The forces driving social capital outcomes are considered and implications for companies and governments are offered.social capital, corporate citizenship, Diageo, community programmes.

Choosing the unstable: Dancing through the mid-career

Whilst professional instability is a lifelong challenge for dance artists, it is in mid career that instability becomes particularly problematic and the issue of sustainability comes to the fore. Mid-career artists build increasingly diverse protean careers in a bid to generate stability whilst dealing with unpredictable work patterns, aging bodies, and increased financial, family and future responsibilities. In addition to this is the sense of physical and emotional loss experienced when the fundamental need to dance is not being fully met. In this study we underscore these big picture issues with a more personal dialogue with three Australian mid-career dance artists. Through these case studies we examine the constant negotiation, reassessment and instability inherent in dance careers. Our research reveals that 'putting the body down' often entails putting down work, status and identity

Economies of Scale and Scope in Network Industries: Lessons for the UK water and sewerage sectors

Many studies of the water and sewerage industries place significant importance on the benefits of economies of scale and scope and how these relate to vertically integrated firms. We have re-examined the early literature on scale and scope economies and find that these studies do not implicitly preclude non-integrated firms from fully utilising assets for multi-product activities; they can still reap scope economies through trading in the open market. Further, we demonstrate difficulties in separating these two types of economies when assessing firm performance. Trade-offs between governance and production costs are a key issue in determining the value of vertically integrated firms that may undergo divestiture. We discuss the present policy debate regarding the optimal structure of the water and sewerage markets in England and Wales in the light of this, and recommend avenues of research that will help determine the optimal policy
