Case studies in web sustainability

At the moment organisations often make significant investments in producing Web-based material, often funded through public money, for example from JISC. But what happens when some of those organisations are closed or there is no longer any money or resources to host the site? We are seeing cuts in funding or changes in governmental policy, which is resulting in the closure of some of these organisations. What happens to those Web resources when the organisations are no longer in existence? Public money has often been used to develop these resources - from that perspective it would be a shame to lose them. Moreover, the resources might be needed or someone may actually want to take over the maintenance of the site at a later date. How do we make these sites more sustainable? Is there any way we can move sites to somewhere that is free to host the Web pages, and can be left there or modified when needed? JISC previously funded three projects to look at this area through a programme called Sustaining ‘at risk’ online resources [1]. One of these projects, which ran at The University of Northampton, looked into ‘rescuing’ one of the recently closed East Midlands Universities Association’s online resources. This resource, called East Midlands Knowledge Network (EMKN), lists many of the knowledge transfer activities of 10 of the East Midlands universities. The project looked at options on how to migrate the site to a free hosting option to make it make it more sustainable even when it is no longer available on the original host’s servers. This article looks at this work as a case study on Web sustainability and also included a case study of another project where Web sustainability was centra

A global environmental right

The development of an international substantive environmental right on a global level has long been a contested issue. To a limited extent environmental rights have developed in a fragmented way through different legal regimes. This book examines the potential for the development of a global environmental right that would create legal duties for all types of decision-makers and provide the bedrock for a new system of international environmental governance. Taking a problem solving approach, the book seeks to demonstrate how straightforward and logical changes to the existing global legal architecture would address some of the fundamental root causes of environmental degradation. It puts forward a draft global environmental right that would integrate duties for both state and non-state actors within reformed systems of environmental governance and a rational framework for business and industry to adhere to in order that those systems could be made operational. It also examines the failures of the existing international climate change regime and explains how the draft global environmental right could remedy existing deficits. This innovative and interdisciplinary book will be of great interest to policy-makers, students and researchers in international environmental law, climate change, environmental politics and global environmental governance as well as those studying the WTO, international trade law, human rights law, constitutional law and corporate law

Measurement system

A measurement system is described for providing an indication of a varying physical quantity represented by or converted to a variable frequency signal. Timing pulses are obtained marking the duration of a fixed number, or set, of cycles of the sampled signal and these timing pulses are employed to control the period of counting of cycles of a higher fixed and known frequency source. The counts of cycles obtained from the fixed frequency source provide a precise measurement of the average frequency of each set of cycles sampled, and thus successive discrete values of the quantity being measured. The frequency of the known frequency source is made such that each measurement is presented as a direct digital representation of the quantity measured

Junkbots

The School of Science and Technology at the University of Northampton have been working with local schools to create robots made from junk and also to use robots programmed by the students to perform simple rubbish clearing exercises. This is an initiative by the University to introduce environmental sustainability, engineering and computing to students in school

Chemical structure matching using correlation matrix memories

This paper describes the application of the Relaxation By Elimination (RBE) method to matching the 3D structure of molecules in chemical databases within the frame work of binary correlation matrix memories. The paper illustrates that, when combined with distributed representations, the method maps well onto these networks, allowing high performance implementation in parallel systems. It outlines the motivation, the neural architecture, the RBE method and presents some results of matching small molecules against a database of 100,000 models

Alessi 95 and the short period Cepheid SU Cassiopeiae

The parameters for the newly-discovered open cluster Alessi 95 are established on the basis of available photometric and spectroscopic data, in conjunction with new observations. Colour excesses for spectroscopically-observed B and A-type stars near SU Cas follow a reddening relation described by E(U-B)/E(B-V)=0.83+0.02*E(B-V), implying a value of R=Av/E(B-V)~2.8 for the associated dust. Alessi 95 has a mean reddening of E(B-V)_(B0)=0.35+-0.02 s.e., an intrinsic distance modulus of Vo-Mv=8.16+-0.04 s.e. (+-0.21 s.d.), d=429+-8 pc, and an estimated age of 10^8.2 yr from ZAMS fitting of available UBV, CCD BV, NOMAD, and 2MASS JHKs observations of cluster stars. SU Cas is a likely cluster member, with an inferred space reddening of E(B-V)=0.33+-0.02 and a luminosity of =-3.15+-0.07 s.e., consistent with overtone pulsation (P_FM=2.75 d), as also implied by the Cepheid's light curve parameters, rate of period increase, and Hipparcos parallaxes for cluster stars. There is excellent agreement of the distance estimates for SU Cas inferred from cluster ZAMS fitting, its pulsation parallax derived from the infrared surface brightness technique, and Hipparcos parallaxes, which all agree to within a few percent.Comment: Accepted for Publication (MNRAS

Asymmetries in Bank of England Monetary Policy

In this paper we estimate limited dependent variable models for Bank of England monetary policy using monthly data over the period June 1997 to March 2003. During this period the Bank has had operational independence to set the interest rate in order to meet the inflation target set by the Government. We find evidence that the Bank has responded to current output growth rather than inflation which is consistent with targeting future inflation when there is a lag in the response of inflation to the output gap. We also find evidence of an asymmetry in the sense that the link between the interest rate and output growth is stronger when an increase in the interest rate is required than when circumstances dictate it should be cut. On the other hand there is considerably more inertia for interest rate cuts in the sense that a cut in the rate in one month significantly increases the probability of a cut in the next month which is not the case for increases

The BSE Crisis and the Price of Red Meat in the UK

This paper presents estimates of price functions for beef, lamb and pork for the UK economy which allow for the effects of the 1996 BSE crisis. Our estimates illustrate the importance of allowing for the joint endogeneity of prices in these markets. We show that the effects of this crisis had a significant negative effect on the price of beef and a positive and significant effect on the price of lamb. However, there appears to have been little effect on the price of pork
