Denial, Silence and the Politics of the Past: Unpicking the Opposition to Truth Recovery in Northern Ireland

There has been considerable and protracted debate on whether a formal truth recovery process should be established in Northern Ireland. Some of the strongest opposition to the creation of such a body has been from unionist political elites and the security forces. Based on qualitative fieldwork, this article argues that the dynamics of denial and silence have been instrumental in shaping their concerns. It explores how questions of memory, identity and denial have created a ‘myth of blamelessness’ in unionist discourse that is at odds with the reasons for a truth process being established. It also examines how three interlocking manifestations of silence – ‘silence as passivity,’ ‘silence as loyalty’ and ‘silence as pragmatism’ – have furthered unionists’ opposition to dealing with the past. This article argues that making peace with the past requires an active deconstruction of these practices.

Voices from higher up the ladder:Exploring the team leader role in call centres

This paper focuses on an under-researched employee category in the call centre literature-the team leader. The paper, drawing on data from nine Australian call centres, finds that the team leader role is integral to the effectiveness of call centres, yet it is a role that consists of considerable complexity and contradictions. The research demonstrates the critical role performed by team leaders: coach, mentor, trainer, performance evaluator, communicator and supervisor. It also shows team leaders as being far more positive about many of the features of the call centre work environment compared with those on the front line. However, there does appear to be a need for greater acknowledgement of their challenging role, the contradictions that are inherent in the job and the need, in many cases, for increased support being made available to assist. © 2013 John Wiley & Sons Ltd.

On the Complexity of Universal Leader Election

Electing a leader is a fundamental task in distributed computing. In its implicit version, only the leader must know who is the elected leader. This paper focuses on studying the message and time complexity of randomized implicit leader election in synchronous distributed networks. Surprisingly, the most "obvious" complexity bounds have not been proven for randomized algorithms. The "obvious" lower bounds of O(m) messages (m is the number of edges in the network) and O(D) time (D is the network diameter) are non-trivial to show for randomized (Monte Carlo) algorithms. (Recent results that show that even O(n) (n is the number of nodes in the network) is not a lower bound on the messages in complete networks, make the above bounds somewhat less obvious). To the best of our knowledge, these basic lower bounds have not been established even for deterministic algorithms (except for the limited case of comparison algorithms, where it was also required that some nodes may not wake up spontaneously, and that D and n were not known).

We establish these fundamental lower bounds in this paper for the general case, even for randomized Monte Carlo algorithms. Our lower bounds are universal in the sense that they hold for all universal algorithms (such algorithms should work for all graphs), apply to every D, m, and n, and hold even if D, m, and n are known, all the nodes wake up simultaneously, and the algorithms can make anyuse of node's identities. To show that these bounds are tight, we present an O(m) messages algorithm. An O(D) time algorithm is known. A slight adaptation of our lower bound technique gives rise to an O(m) message lower bound for randomized broadcast algorithms.

An interesting fundamental problem is whether both upper bounds (messages and time) can be reached simultaneously in the randomized setting for all graphs. (The answer is known to be negative in the deterministic setting). We answer this problem partially by presenting a randomized algorithm that matches both complexities in some cases. This already separates (for some cases) randomized algorithms from deterministic ones. As first steps towards the general case, we present several universal leader election algorithms with bounds that trade-off messages versus time. We view our results as a step towards understanding the complexity of universal leader election in distributed networks.

Joining the `Crusade against the Giants': Keir Hardie's Fairy Tales and The Socialist Child Reader

This article focuses on Keir Hardie's forgotten fiction and journalism for children, published in his paper The Labour Leader during the 1890s. It argues that Hardie's dialogue with child correspondents was shaped by a socialist periodical culture that redefined reading as a communal, political activity. Relating Hardie's appropriation of fantasy to that of a fellow socialist editor, John Trevor, the article examines the fairy tale as a propaganda tool in the process of `making socialists', but also questions the model of child readers as passive consumers, arguing that young readers were both empowered and controlled by Hardie's journalistic strategies.

Kingship by Descent or Kingship by Election? The Contested Title of James VI and I

Throughout the reign of Elizabeth I, a steady stream of tracts appeared in English print to vindicate the succession of the most prominent contenders, Mary and James Stuart of Scotland. This article offers a comprehensive account of the polemical battle between the supporters and opponents of the Stuarts, and further identifies various theories of English kingship, most notably the theory of corporate kingship, developed by the Stuart polemicists to defend the Scottish succession. James's accession to the English throne in March 1603 marked the protracted end of the debate over the succession. The article concludes by suggesting that, while powerfully renouncing the opposition to his succession, over the course of his attempt to unify his two kingdoms, James and his supporters ultimately departed from the polemic of corporate kingship, for a more assertive language of kingship by natural and divine law.

Accounts of debates in the House of Commons, March– April 1731, supplementary to the diary of the first earl of Egmont

John Perceval (1685–1748), 1st Viscount Perceval and (from 1733) 1st Earl of Egmont, was an assiduous recorder of his own life and times. His diaries, published by the Historical Manuscripts Commission from manuscripts in the British Library, are the best source for parliamentary debates at Westminster in the 1730s. For the years 1730-1733, when Perceval sat in the Commons (as an Irish peer) they are remarkably full. His practice seems to have been to prepare two versions (presumably on the basis of notes taken in the House), the first attributing speeches to individuals, and the second, entered up in the diary, which listed speakers and summarized all arguments on each side. His letterbooks for 1731 contain accounts of five debates that embody his first editing process, with speeches attributed to individuals. They were sent to an Irish correspondent, Marmaduke Coghill, and largely omitted from the diary because Perceval had already transcribed them elsewhere. They are new to historians and cast light on two main issues: the unsuccessful attempts by Perceval and the ‘Irish lobby’ to persuade the British parliament to settle the Irish woollen trade, a question bedevilling Anglo-Irish relations in this period; and an attempt by the opposition to stir up anger against perceived Spanish aggression against Gibraltar. One of the most interesting features is the insight afforded into the Commons performances of Sir Robert Walpole: his management of debates, his own style of speaking, and his sharp exchanges with opponents like William Pulteney.

The evolution of offshore wind power in the United Kingdom

In the United Kingdom wind power is recognised as the main source of renewable energy to achieve the European Union 2020 renewable energy targets. Currently over 50% of renewable power is generated from onshore wind with a large number of offshore wind projects in development. Recently the government has re-iterated its commitment to offshore wind power and has announced that offshore wind subsidies are to increase from £135/MWh to £140/MWh until 2019. This paper provides a detailed overview of the offshore wind power industry in the United Kingdom in terms of market growth, policy development and offshore wind farm costs. The paper clearly shows that the United Kingdom is the world leader for installed offshore wind power capacity as pro-active policies and procedures have made it the most attractive location to develop offshore wind farm arrays. The key finding is that the United Kingdom has the potential to continue to lead the world in offshore wind power as it has over 48 GW of offshore wind power projects at different stages of operation and development. The growth of offshore wind power in the United Kingdom has seen offshore wind farm costs rise and level off at approximately £3 million/MW, which are higher than onshore wind costs at £1.5–2 million/MW. Considering the recent increase in offshore wind power subsidies and plans for 48 GW of offshore wind power could see more offshore wind power becoming increasingly financially competitive with onshore wind power. Therefore offshore wind power is likely to become a significant source of electricity in the United Kingdom beyond 2020.

Challenging the SD benefits attributed to sport Mega-Events hosting

Sport Mega-event hosting faces opposition that is manifested with different intensity during the different phases of the event, from its inception as an idea to its delivery and legacy. Some Social Movements Organisations (SMOs) have acted as indefatigable monitors of the Sustainable Development (SD) dimension of sporting events in general and, in some of the most recent sport mega-events, in particular the Olympics, they have served as important advisors and facilitators. Nevertheless, in many cases we see enthusiastic supporters turning to vehemently challenging whatever positives have been associated with hosting the event. In addition, there is opposition to sport Mega-events in their entirety. That type of opposition tends to employ a holistic prism that manages to identify multiple interconnected negative aspects of hosting a sport mega-event and incorporate them into an anti-systemic discourse. It is important to bear in mind that irrespective of many proclamations to the opposite as far as megas are concerned (projects and/or events), a number of studies have demonstrated that citizen participation and democratic accountability in decision-making have been notoriously absent. After all, the idea of citizen participation in the planning of sport mega-event is essentially the public response to a plan conceived by others. There were, of course, some notable cases of democratic consultation at the early stages of bidding to host a sport mega-event but these more democratic approaches resulted in the failure of the bid (for e.g. Toronto 1996). The knowledge of this by the groups that initiated the hosting idea and the bidding process has led to discouraging in depth public consultation that may fit perfectly to the democratic process but not to the tight schedules of associated projects completion. That produces ‘autocracy against which opposition may arise’ (Hiller, 2000, p. 198). It is this democratic deficit that has led to important instances of social contestation and protest mobilizations by citizen groups as well as the more regular corps of social activists. From a perspective borrowed from the sociology of protest and social movements, sport mega-events hosting can operate as an issue that stimulates protest activities by an existing protest milieu and new actors as well as an important mobilizing resource. In fact, some scholars have also argued that the Olympic Games were an important frame for the transnational activism that was marked by anti-globalization protest in Seattle in 1999 (Cottrell & Nelson, 201; Lenskyj, 2008). In addition, it’s important not to lose sight of other acts dissent that take place in relatively close proximity, about a year before the event when most infrastructural and societal changes brought by hosting the event and impact start to become apparent by the host communities, like the rioting of August 2011 in the London Olympic Boroughs and the 2012 riots of June 2013 in Sao Paulo and other Brazilian cities. This paper starts by outlining the SD claims made in the bidding to host the summer Olympic Games by five prospective hosts (Sydney; Athens; Beijing; London and Rio) proceeds towards examining the opposition and challenges that was manifested in relation to these claims. In Particular it provides an assessment of protest-events over the aforementioned different phases of sport mega-events hosting. A different picture emerges for each of the host nation that is partly explained by local, national and global configuration of protest politics. Whereas the post-event legacy of the first two hosts of the Games can be assessed and that way see the validity of claims made by challengers in the other phases, in the other three cases, the implementation of Olympic Games Impact (OGI) studies offers the tool for discussing the post-event phase for Beijing and London and engage in a speculative exercise for the case of Rio. Judging by available findings, the paper concludes that the SD aspiration made in the bid documents are unlikely to be met and social contestation based on the same issues is likely to increase due to the current global economic crisis and BRICS, like China and Brazil, having entered the process of becoming global economic hegemons.

Locally Unwanted Sea Use: The Case of Syrian Chemical weapons disposal in the Mediterranean

This paper discusses the opposition to the disposal of Syrian chemical weapons in the Mediterranean Sea. Following insights from Green criminology and recent calls in that discipline for the inclusion of new social movements and resistance, it discusses in detail how the issue was framed in terms of environmental and ecological justice by different protest actors. This process is aided by an analytical model that brings together the sociology of protest and social movements, insights from reflexive modernisation and the study of southern European civil societies. Methodologically, the focus is on mobilisations that took place in Greece in general and the island of Crete in particular. Data have been harvested through the examination of online sources, such as newspapers, blogs and dedicated social networks. The analysis of the findings suggests that these mobilisations were initially stimulated by real concern, but subsequently these were only carried through by certain movement entrepreneurs who didn’t hesitate to pepper these concerns with false claims and/or linkages to an already active anti-imperialist discourse.

Sustainable Rural Tourism: Lessons for Rural Development

Rural areas are recognised for their complex, multi-functional capacities with a range of different interest groups claiming their rights to, and use of, different rural spaces. The current rural development paradigm that is evident across the globe is epitomised by the European LEADER approach. Using evidence from the proposed National Park in Northern Ireland, we ask the question: what is the potential of sustainable rural tourism to contribute to rural development? Within our analysis we consider the scope for adaptive tourism to overcome some of the ongoing challenges that have been identified within the LEADER approach. Four themes are revealed from this analysis: institutional (in)capacity; legitimacy of local groups; navigating between stakeholder interests; and sustainable tourism in practice. These issues, discussed in turn, have clear implications for the new rural development programme.

Public Accountability: a critical approach

'Public Accountability' has been variously described as, for example, Chameleon-like, as everexpanding and as an iconic concept. Public accountability (PA) is a contested but fundamental concept in the structure of contemporary public services. However, much of the existing literature on PA can be seen as reductionist or managerialist. The experiences of public service-users rarely feature and certainly not in the context as a potential agent for change. A second related strand concerns the introduction of New Public Management (NPM) models, and their impact on accountability in the public sector. A central line of argument is that to overcome the reductionist approaches researchers need to place their work in the broad context of these changes. To that end, this paper sets out a critical conceptualisation of 'public accountability', where it is seen as a dynamic social relationship through which civil society seeks to control and challenge the state. This critical PA conceptualisation is then applied to the context of Social Housing in England. The analysis highlights key changes in the structure of accountability relationships, but also stresses the opposition that the reforms have generated. Finally, the conclusion draws links to the debates in the anti-capitalist movement as providing a source of possible research projects.

A techno-economic evaluation of changing from conventional vehicles to range extended electric vehicles

Transportation accounts for 22% of greenhouse gas emissions in the UK, and increases to 25% in Northern Ireland. Surface transport carbon dioxide emissions, consisting of road and rail, are dominated by cars. Demand for mobility is rising rapidly and vehicle numbers are expected to more than double by 2050. Car manufacturers are working towards reducing their carbon footprint through improving fuel efficiency and controlling exhaust emissions. Fuel efficiency is now a key consideration of consumers purchasing a new vehicle. While measures have been taken to help to reduce pollutants, in the future, alternative technologies will have to be used in the transportation industry to achieve sustainability. There are currently many alternatives to the market leader, the internal combustion engine. These alternatives include hydrogen fuel cell vehicles and electric vehicles, a term which is widely used to cover battery electric vehicles, plug-in hybrid electric vehicles and extended-range electric vehicles. This study draws direct comparisons measuring the differing performance in terms of fuel consumption, carbon emissions and range of a typical family saloon car using different fuel types. These comparisons will then be analysed to see what effect switching from a conventionally fuelled vehicle to a range extended electric vehicle would have not only on the end user, but also the UK government.

A hybrid harmony search with arithmetic crossover operation for economic dispatch

Economic dispatch (ED) problems often exhibit non-linear, non-convex characteristics due to the valve point effects. Further, various constraints and factors, such as prohibited operation zones, ramp rate limits and security constraints imposed by the generating units, and power loss in transmission make it even more challenging to obtain the global optimum using conventional mathematical methods. Meta-heuristic approaches are capable of solving non-linear, non-continuous and non-convex problems effectively as they impose no requirements on the optimization problems. However, most methods reported so far mainly focus on a specific type of ED problems, such as static or dynamic ED problems. This paper proposes a hybrid harmony search with arithmetic crossover operation, namely ACHS, for solving five different types of ED problems, including static ED with valve point effects, ED with prohibited operating zones, ED considering multiple fuel cells, combined heat and power ED, and dynamic ED. In this proposed ACHS, the global best information and arithmetic crossover are used to update the newly generated solution and speed up the convergence, which contributes to the algorithm exploitation capability. To balance the exploitation and exploration capabilities, the opposition based learning (OBL) strategy is employed to enhance the diversity of solutions. Further, four commonly used crossover operators are also investigated, and the arithmetic crossover shows its efficiency than the others when they are incorporated into HS. To make a comprehensive study on its scalability, ACHS is first tested on a group of benchmark functions with a 100 dimensions and compared with several state-of-the-art methods. Then it is used to solve seven different ED cases and compared with the results reported in literatures. All the results confirm the superiority of the ACHS for different optimization problems.
