Risk versus National Pride. Conflicting discourses over the construction of a High Voltage Power Station in the Athens Metropolitan Area for demands of the 2004 Olympics

This paper first explores the conflictual discourses employed by government agencies, citizens’ initiatives, and environmental organizations over the construction of a High Voltage Power Station (KYT) for demands of the 2004 Olympic Games, as presented in media reports and movement literature over a period of one year. Having in mind recent criticisms targeting the lack of empirical evidence in Ulrich Beck’s risk theorization, this exploration is of distinct importance. Secondly, it takes into account that both the defensive character of societal action and mistrust to expert authorities have been confirmed as prevalent characteristics of both the Greek and the general risk social context. The paper attempts to re-evaluate and/or complement existing perspectives of societal activism in general and environmental mobilizations in particular within the confines of the Greek social context. As a tentative conclusion, it is suggested that the risk perspective offers a novel prism for the examination of societal activism without confining it to the characteristics of individual national contexts.

Consociationalism and the evolution of political cleavages in Northern Ireland, 1989-2004

Political cleavages are often understood as deriving from either deep-rooted social divisions or institutional incentives. Contemporary Northern Ireland provides a test of the mutability of apparently entrenched cleavages to institutional change. Research undertaken before the ceasefire in the 1990s found noticeable asymmetries in the patterns of cleavage within the unionist and nationalist blocs. Within the unionist bloc, economic 'left-right' issues formed the main ideological division between the two major unionist parties. This contrasted with an ethno-national source of ideological division between the two nationalist parties. The emergence of a consociational form of government structure since then has demonstrated the ability of institutional incentives to swiftly reform some aspects of party competition however. As evidence of this, we show that between 1989 and 2004 there was little change in the sources of support for Sinn F�©in relative to the SDLP, but the influence of left-right ideology within the unionist bloc was negated as the influence of ethno-nationalism dramatically increased.

Multivariate prediction of clarified butter composition using Raman spectroscopy

Raman spectroscopy has been used to predict the abundance of the FA in clarified butterfat that was obtained from dairy cows fed a range of levels of rapeseed oil in their diet. Partial least squares regression of the Raman spectra against FA compositions obtained by GC showed good prediction for the five major (abundance >5%) FA with R-2=0.74-0.92 and a root mean SE of prediction (RMSEP) that was 5-7% of the mean. In general, the prediction accuracy fell with decreasing abundance in the sample, but the RMSEP was 1.25%. The Raman method has the best prediction ability for unsaturated FA (R-2=0.85-0.92), and in particular trans unsaturated FA (best-predicted FA was 18:1 tDelta9). This enhancement was attributed to the isolation of the unsaturated modes from the saturated modes and the significantly higher spectral response of unsaturated bonds compared with saturated bonds. Raman spectra of the melted butter samples could also be used to predict bulk parameters calculated from standard analyzes, such as iodine value (R-2=0.80) and solid fat content at low temperature (R-2=0.87). For solid fat contents determined at higher temperatures, the prediction ability was significantly reduced (R-2=0.42), and this decrease in performance was attributed to the smaller range of values in solid fat content at the higher temperatures. Finally, although the prediction errors for the abundances of each of the FA in a given sample are much larger with Raman than with full GC analysis, the accuracy is acceptably high for quality control applications. This, combined with the fact that Raman spectra can be obtained with no sample preparation and with 60-s data collection times, means that high-throughput, on-line Raman analysis of butter samples should be possible.
