Consociational institutional arrangements in deeply divided societies are often criticised for cementing the underlying conflict cleavage, encouraging the continued dominance of conflict-based party competition and voter behaviour and prohibiting the emergence of 'normal' (that is, non-conflict-based) dimensions of political competition. However, drawing on evidence from a post-election survey at the 2009 Northern Ireland election to the European Parliament, I find that EU issues determined intra-bloc vote choice (at least in the nationalist community). This suggests that there is potential for regional integration projects, such as the EU, to contribute to the normalisation of politics in a consociational system by acting as the source of an externally generated dimension of political competition. © 2012 Macmillan Publishers Ltd.

Relatively few measurements of the solar phase function of cometary nuclei exist, despite the importance of this parameter in determining accurate sizes and its use in modeling surface properties. We make use of robotic telescopes and servicemode observing to monitor cometary nuclei over months at a time, combining intensive observations at a single epoch with regular short light-curve segments to efficiently account for brightness changes due to both nucleus rotation and changing solar phase angle. We present our latest results on comets 8P/Tuttle, 14P/Wolf, 67P/Churyumov- Gerasimenko and 110P/Hartley 3.

Quantum-dot cellular automata (QCA) is potentially a very attractive alternative to CMOS for future digital designs. Circuit designs in QCA have been extensively studied. However, how to properly evaluate the QCA circuits has not been carefully considered. To date, metrics and area-delay cost functions directly mapped from CMOS technology have been used to compare QCA designs, which is inappropriate due to the differences between these two technologies. In this paper, several cost metrics specifically aimed at QCA circuits are studied. It is found that delay, the number of QCA logic gates, and the number and type of crossovers, are important metrics that should be considered when comparing QCA designs. A family of new cost functions for QCA circuits is proposed. As fundamental components in QCA computing arithmetic, QCA adders are reviewed and evaluated with the proposed cost functions. By taking the new cost metrics into account, previous best adders become unattractive and it has been shown that different optimization goals lead to different “best” adders.

This book draws on interview material with more than 100 evangelicals. We ask why do people born into the same religious community turn out so differently? We tell the stories of pro-life DUP picketers, liberal peace-campaigning ministers, housewives afraid of the devil, students deconstructing their faith and atheists mortified by their religious past. We explore why people have chosen to go in one religious direction or another, and how their religious journeys have unfolded.
