The United States, PMSCs and the state monopoly on violence: Leading the way towards norm change

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2013 Sage.The proliferation of private military and security companies (PMSCs) in Iraq and Afghanistan has raised many questions regarding the use of armed force by private contractors. This article addresses the question of whether the increased acceptance of PMSCs indicates a transformation of the international norm regarding the state monopoly on the legitimate use of armed force. Drawing on theoretical approaches to the analysis of norm change, the article employs four measures to investigate possible changes in the strength and meaning of this norm: modifications in state behaviour, state responses to norm violation, the promulgation of varying interpretations of the norm in national and international laws and regulations, and changes in norm discourse. Based on an analysis of empirical evidence from the United States of America and its allies, the article concludes that these measures suggest that the USA is leading the way towards a transformation of the international norm of the state monopoly on violence, involving a revised meaning. Although this understanding has not yet been formally implemented in international law, it has allowed a growing number of countries to tolerate, accept or legalize the use of armed force by PMSCs in the international arena.The Alexander von Humboldt Foundation and the Peace Research Institute Frankfurt

Women candidates and councillors in Scottish local government, 1974-2012

While significant attention has been paid to the levels of representation of women in both the Westminster Parliament and the Scottish Parliament, much less considered has been given to the position within local government. This article addresses that deficit for Scotland. It shows that for twenty-five years following the reorganisation of local government in Scotland in 1974 there was a slow but relatively steady increase in the numbers of female candidates and councillors, although more recently this appears to have since plateaued somewhat, together with a similar increase in the number of women councillors taking up more senior roles in Scotland’s councils. The article analyses the representation of women in Scottish local government over the period from 1974 to 2012 against the backdrop of significant change in Scotland, including a further restructuring of local government and the introduction of the Single Transferable Vote for council elections, the creation of the Scottish Parliament, the rise of the SNP and the decline of the Conservative Party

Tackling 3D ToF Artifacts Through Learning and the FLAT Dataset

Scene motion, multiple reflections, and sensor noise introduce artifacts in the depth reconstruction performed by time-of-flight cameras. We propose a two-stage, deep-learning approach to address all of these sources of artifacts simultaneously. We also introduce FLAT, a synthetic dataset of 2000 ToF measurements that capture all of these nonidealities, and allows to simulate different camera hardware. Using the Kinect 2 camera as a baseline, we show improved reconstruction errors over state-of-the-art methods, on both simulated and real data.Comment: ECCV 201

The solar influence on the probability of relatively cold UK winters in the future

Recent research has suggested that relatively cold UK winters are more common when solar activity is low (Lockwood et al 2010 Environ. Res. Lett. 5 024001). Solar activity during the current sunspot minimum has fallen to levels unknown since the start of the 20th century (Lockwood 2010 Proc. R. Soc. A 466 303–29) and records of past solar variations inferred from cosmogenic isotopes (Abreu et al 2008 Geophys. Res. Lett. 35 L20109) and geomagnetic activity data (Lockwood et al 2009 Astrophys. J. 700 937–44) suggest that the current grand solar maximum is coming to an end and hence that solar activity can be expected to continue to decline. Combining cosmogenic isotope data with the long record of temperatures measured in central England, we estimate how solar change could influence the probability in the future of further UK winters that are cold, relative to the hemispheric mean temperature, if all other factors remain constant. Global warming is taken into account only through the detrending using mean hemispheric temperatures. We show that some predictive skill may be obtained by including the solar effect

Why Parliament Now Decides on War: Tracing the Growth of the Parliamentary Prerogative through Syria, Libya and Iraq

Research Highlights and Abstract: Precedents set in debates over Iraq, Libya and Syria established a new parliamentary prerogative, that MPs must vote before military action can legitimately be launched. Tony Blair conceded the Iraq vote to shore up Labour back-bench support, because he was convinced he would win, and because he was unwilling to change course regardless. David Cameron allowed a vote on Libya because he believed parliament should have a say, because UN support meant he was certain to win, and to gain plaudits for not being Blair. Cameron then had to allow a vote on Syria despite its greater political sensitivity. He mishandled the vote, and lost, and felt constrained to pull out of mooted military action. Collectively these three precedents comprise a new constitutional convention, which will constrain the executive in future whether the law is formally changed or not. Parliament now decides when Britain goes to war. The vote against military intervention in Syria on 29 August 2013 upheld a new parliamentary prerogative that gradually developed through debates over earlier actions in Iraq and Libya. While the academic community and much of the British political elite continue to focus on the free rein granted to prime ministers by the historic royal prerogative, this article argues it is critically constrained by its parliamentary counterpart. It traces the way political conditions, individual policymaker preferences, and the conventional nature of the unwritten British constitution allowed parliament to insert itself into the policymaking process without the consent of successive governments. It concludes that MPs will in future expect the right to vote on proposals to deploy the armed forces overseas, and that the legitimacy of military action will depend on the government winning such a vote

Digital Watchdogs? Data reporting and the traditional 'fourth estate' role for journalists

As governments throughout the world transition to storing and releasing vast amounts of numerical information digitally, journalists are increasingly using digital data reporting as an investigative tool to report on issues in the public interest and to hold government - elected officials and bureaucracy – to account. Through a series of qualitative interviews with data journalists in 17 countries, this article examines the impact that digital data reporting is having on the traditional role of journalism as a fourth estate. Findings suggest the emergence of digital data reporting as a key tool in accountability journalism and in informing and engaging the public. However, the failure of popular ‘tabloid’ journalism to engage with data journalism means that a new technologically adept and data-informed elite class is on the rise, with important implications for democratic processes in advanced societies

Reaching in? The potential for E-petitions in local government in the United Kingdom

This article considers the extent to which petitions and e-petitions might allow citizens to ‘reach in’ to local authorities in the United Kingdom. It examines how e-petitions sit against wider debates about the use of technology and digital democracy and the extent to which petitions systems might align with traditional approaches to representative democracy. It highlights that, as with many other participative initiatives, digital or otherwise, there are a variety of issues and risks associated with e-petitions, including those associated with broad socio-economic factors, and others that are more specifically related to the use of e-petitions. However, drawing on existing examples of e-petitions systems in the UK, it suggests that, designed well, they may have potential value, not simply in terms of enabling ‘voice’ and participation, but also in helping educate and inform petitioners about local democracy and decision-making
