BSE crisis and food safety regulation: a comparison of the UK and Germany

The BSE crisis represents one of the worst policy disasters experienced by a UK government in recent years. In material terms, it led to the slaughter of 3.3 million cattle and an estimated economic loss of £3.7 billion. In administrative terms, the crisis led to the dissolution of the Ministry of Agriculture, Fisheries and Food (MAFF), an institution that was heavily criticised by the Phillips Inquiry for its lack of openness and transparency. Although far less severe in terms of its economic impact, with estimated losses of between Euro 0.8 and 1.05 billion, the German BSE crisis resulted in extensive political fallout, leading, inter alia, to the resignation of two government ministers. This paper compares the handling of the crisis in the UK and Germany and the regulation put in place in its aftermath. It explores the reasons for the failure of both governments to manage this crisis in a credible, timely and proactive fashion. Examining the institutional contexts in which decisions about scientific evidence on BSE were made, the paper argues that, in both countries, a centralised system, in which government agencies controlled “science for government”, was vulnerable to expert-interest group alliances which undermined the potential for a credible assessment of public health and safety risks. Looking at the policies adopted in the aftermath of these crises, the paper notes that, although being far less affected by BSE, Germany paradoxically adopted far more rigorous measures for the prevention of future incidents, which included the strict administrative separation of the risk assessment and management functions. Our paper concludes that the extent of administrative reforms which are initiated in response to crises is more likely to correspond to that general receptiveness of the political environment to these reforms, than the ‘objective’ impact of the crisis itself

The CF6 Jet Engine Performance Improvement - Low Pressure Turbine Active Clearance Control

A low pressure turbine (LPT) active clearance control (ACC) cooling system was developed to reduce the fuel consumption of current CF6-50 turbofan engines for wide bodied commercial aircraft. The program performance improvement goal of 0.3% delta sfc was determined to be achievable with an improved impingement cooling system. The technology enables the design of an optimized manifold and piping system which is capable of a performance gain of 0.45% delta sfc

Prospective cognitions in anxiety and depression: Replication and methodological extension

The present study presents a replication and methodological extension of MacLeod, Tata, Kentish, and Jacobsen (1997) with a nonclinical sample, using future-directed imagery to assess prospective cognitions. Results showed that only anxiety (but not depression) was related to enhanced imagery for future negative events. Both anxiety and depression showed significant zero-order correlations with reduced imagery for future positive events. However, when the overlap between anxiety and depression was controlled for, only depression (but not anxiety) showed a unique association with reduced imagery for positive events. Implications of these findings for cognitive models of anxiety and depression are discussed

Transverse electric scattering widths for strips-Fourier transform technique

A technique which is based on Fourier transformations is introduced for predicting scattering widths. For a strip it is shown that explicit determination of the linear current density is not necessary for bistatic or monostatic scattering width calculations. Comparisons of the predictions of the technique are made with the integral equation technique predictions, which do not require explicit evaluations of linear current densities

A search for extended radio emission from selected compact galaxy groups

Context. Studies on compact galaxy groups have led to the conclusion that a plenitude of phenomena take place in between galaxies that form them. However, radio data on these objects are extremely scarce and not much is known concerning the existence and role of the magnetic field in intergalactic space. Aims. We aim to study a small sample of galaxy groups that look promising as possible sources of intergalactic magnetic fields; for example data from radio surveys suggest that most of the radio emission is due to extended, diffuse structures in and out of the galaxies. Methods. We used the Effelsberg 100 m radio telescope at 4.85 GHz and NRAO VLA Sky Survey (NVSS) data at 1.40 GHz. After subtraction of compact sources we analysed the maps searching for diffuse, intergalactic radio emission. Spectral index and magnetic field properties were derived. Results. Intergalactic magnetic fields exist in groups HCG 15 and HCG 60, whereas there are no signs of them in HCG 68. There are also hints of an intergalactic bridge in HCG 44 at 4.85 GHz. Conclusions. Intergalactic magnetic fields exist in galaxy groups and their energy density may be comparable to the thermal (X-ray) density, suggesting an important role of the magnetic field in the intra-group medium, wherever it is detected.Comment: 13 pages, 4 figures, 3 tables, accepted for publication in A&

Counting statistics and detector properties of quantum point contacts

Quantum detector properties of the quantum point contact (QPC) are analyzed for arbitrary electron transparency and coupling strength to the measured system and are shown to be determined by the electron counting statistics. Conditions of the quantum-limited operation of the QPC detector which prevent information loss through the scattering time and scattering phases are found for arbitrary coupling. We show that the phase information can be restored and used for the quantum-limited detection by inclusion of the QPC detector in the electronic Mach-Zehnder interferometer.Comment: 4 pages, 2 figures, published versio
