BEACON: A Cloud Network Federation Framework

This paper presents the BEACON Framework, which will enable the provision and management of cross-site virtual networks for federated cloud infrastructures in order to support the automated deployment of applications and services across different clouds and datacenters. The proposed framework will support different federation architectures, going from tightly coupled (datacenter federation) to loosely coupled (cloud federation and multi-cloud orchestration) architectures, and will enable the creation of Layer 2 and Layer 3 overlay networks to interconnect remote resources located at different cloud sites. A high level description of the main components of the BEACON framework is also introduced

The effects of stand characteristics on the understory vegetation in Quercus petraea and Q. cerris dominated forests

The shelterwood system used in Hungary has many effects on the composition and structure of the herb layer. The aim of our study was to identify the main variables that affect the occurence of herbs and seedlings in Turkey oak-sessile oak (Quercus cerris and Q. petraea) stands. The study was carried out in the Bükk mountains, Hungary. 122 sampling plots were established in 50-150 year old oak forests, where we studied the species composition and structure of the understorey and overstorey. The occurence of herbs was affected by canopy closure, the heterogenity and patchiness of the stand, the slope and the east-west component of the aspect. The composition of saplings was significantly explained by the ratio of the two major oak species in the stand and the proximity of the adult plants. An important result for forest management was that sessile oaks were able to regenerate almost only where they were dominant in the overstorey

‘Team GB’ or ‘Team Scotland’? Media representations of ‘Britishness’ and ‘Scottishness’ at London 2012 and Glasgow 2014

This article critically reflects upon media coverage of the 2012 London Olympic Games and the 2014 Glasgow Commonwealth Games, scrutinising the emergent discursive constructions of ‘Britishness’ and ‘Scottishness’ through an examination of both London-based (English) and Scotland-based publications. Drawing upon Dayan and Katz’s (1992) portrayal of ‘media events’, the article explores how both events presented competing sites of symbolic struggle during a period of constitutional and political turmoil. Consideration is given to the existence of a ‘hegemonic Britishness’ in print media narratives of these events, as evident in the emergent connotations associated with ‘British nationalism’ and ‘Scottish separatism’

It is Time for New Perspectives on How to Fight Bloat in GP

The present and future of evolutionary algorithms depends on the proper use of modern parallel and distributed computing infrastructures. Although still sequential approaches dominate the landscape, available multi-core, many-core and distributed systems will make users and researchers to more frequently deploy parallel version of the algorithms. In such a scenario, new possibilities arise regarding the time saved when parallel evaluation of individuals are performed. And this time saving is particularly relevant in Genetic Programming. This paper studies how evaluation time influences not only time to solution in parallel/distributed systems, but may also affect size evolution of individuals in the population, and eventually will reduce the bloat phenomenon GP features. This paper considers time and space as two sides of a single coin when devising a more natural method for fighting bloat. This new perspective allows us to understand that new methods for bloat control can be derived, and the first of such a method is described and tested. Experimental data confirms the strength of the approach: using computing time as a measure of individuals' complexity allows to control the growth in size of genetic programming individuals

Sport and policy in ‘contested nations’ : analysing policy and political considerations in Taiwan and Scotland

Policy learning from other international contexts is an important strategy during the sport policy making process for the government of Taiwan, and recent research has examined the potential parallels between Taiwan and Scotland with regards to sports policy.  Although the status of Taiwan and Scotland is not the same, interesting comparisons can be made given their shared status as ‘contested nations’ that are often in the shadow of their closest neighbours with whom there is an uneasy political relationship – respectively, China and England. As a consequence, sport is regarded in both countries as an important vehicle for establishing and promoting a distinctive identity, albeit with contrasting political and policy considerations. Drawing upon 15 semi-structured interviews with sports policymakers and politicians from both the Taiwanese and Scottish contexts, this paper critically examines the similarities and contrasts with regards to the political considerations which shape and constrain the nature of sport policy in each context. This analysis will focus on the role of central government, local government, sport policy organisations, and sporting National Governing Bodies in both Taiwan and Scotland, with particular emphasis on the positioning of sport within the broader policy, political, ideological and constitutional considerations for policymakers in each context

Moving carbon between spheres, the potential oxalate-carbonate pathway of Brosimum alicastrum Sw.; Moraceae.

Aims The Oxalate-Carbonate Pathway (OCP) is a biogeochemical process that transfers atmospheric CO2 into the geologic reservoir as CaCO3; however, until now all investigations on this process have focused on species with limited food benefits. This study evaluates a potential OCP associated with Brosimum alicastrum, a Neotropical species with agroforestry potential (ca. 70–200 kg-nuts yr−1), in the calcareous soils of Haiti and Mexico. Methods / results Enzymatic analysis demonstrated significant concentrations of calcium oxalate (5.97 % D.W.) were associated with B. alicastrum tissue in all sample sites. The presence of oxalotrophism was also confirmed with microbiological analyses in both countries. High concentrations of total calcium (>7 g kg−1) and lithogenic carbonate obscured the localised alkalinisation and identification of secondary carbonate associated with the OCP at most sample sites, except Ma Rouge, Haiti. Soils adjacent to subjects in Ma Rouge demonstrated an increase in pH (0.63) and CaCO3 concentration (5.9 %) that, when coupled with root-like secondary carbonate deposits in Mexico, implies that the OCP does also occur in calcareous soils. Conclusions Therefore this study confirms that the OCP also occurs in calcareous soils, adjacent to B. alicastrum, and could play a fundamental and un-accounted role in the global calcium-carbon coupled cycle

MCS0006 - Major cultural and sporting events

Given the specific question in this DCMS ‘Call for Evidence’ on ‘What needs to happen for major events to successfully bring people from all four nations of the UK together?’, it is clear that the Department is explicitly acknowledging the political and symbolic importance of sport and sporting events - a position that we support as academics within the field of the sociology and politics of sport. To this end, we argue that such refutation of the ‘sport and politics do not mix’ fallacy is important to shed light on the political and ideological impact of sporting events, drawing upon our empirical evidence from past sporting events. In considering whether the hosting of major events can successfully bring people from all four nations of the UK together, policymakers require a critical appreciation of the double-edged symbolism of international sporting events in relation to national identity in the UK. In this vein, we draw upon an extensive body of research that has investigated this element of national identity politics at the following sporting events: a) London 2012 Olympic Games; b) Glasgow 2014 Commonwealth Games; c) Gleneagles 2019 Solheim Cup; and, d) Portrush 2020 Open Championship. In light of the above comments regarding the double-edged symbolism of international sporting events in relation to national identity in the UK, we set out below the ways in which past sporting events have offered potential for unifying symbolism which responds in the affirmative (in a caveated manner) to the Call for Evidence proposition of using ‘...major events to successfully bring people from all four nations of the UK together’. Equally, we also contend that past sporting events simultaneously offered potential for the growth of distinctive national identities - and to a lesser degree, political nationalism - which suggests that the proposition of using ‘...major events to successfully bring people from all four nations of the UK together’ can potentially be counter-productive. Our evidence argues that sport can act as an additional marker of difference between the ‘home nations’, underpinning a sense of distinctiveness within British identity politics. Notwithstanding these comments, it is also important for politicians and policy-makers to avoid conflation between sporting nationalism and political nationalism in relation to sporting events, given the lack of evidence of such correlation. Therefore, the question of whether major events can successfully bring people from all four nations of the UK together needs to be considered in a measured and realistic degree - to this end, we specifically draw upon extensive evidence from the Scottish context. In order for major sporting events to be successfully used to bring people from all four nations of the UK together, policymakers need to be wary of the dangers of the conflation between Britishness and Englishness at international sporting events which can become evident at international sporting events. Such conflation often leads to the alienation of the Scottish, Welsh and Northern Irish population. Furthermore, there are risks entailed with regards to the recent increase in symbolism of the United Kingdom in political communication, such as the recent promotion of the Union Flag in public communication and government buildings, if this is replicated at international sporting events. This would potentially undermine the potential to use such events to bring people from all four nations of the UK together. Finally, we would like to stress that a sensitive and respectful approach to the use of sporting events to bring people from all four nations of the UK together, mindful of the arguments presented above, does indeed possess potential benefits which make the pursuit of sporting events worthwhile. Thus, we reiterate evidence of the potential for harnessing intangible ‘legacies’ of sporting events, such as image promotion, diplomatic goodwill, reconciliation, and ‘feel-good factor’, for achieving broader cultural, social and economic goals. However, to achieve these goals, acknowledging such negative images of ‘Britishness’ is crucial

A Social Identity Approach to Sport Psychology: Principles, Practice, and Prospects.

Drawing on social identity theory and self-categorization theory, we outline an approach to sport psychology that understands groups not simply as features of sporting contexts but rather as elements that can be, and often are, incorporated into a person's sense of self and, through this, become powerful determinants of their sport-related behavior. The underpinnings of this social identity approach are outlined, and four key lessons for sport that are indicative of the analytical and practical power of the approach are presented. These suggest that social identity is the basis for sports group (1) behavior, (2) formation and development, (3) support and stress appraisal, and (4) leadership. Building on recent developments within sport science, we outline an agenda for future research by identifying a range of topics to which the social identity approach could fruitfully contribute

Women, war and sport: the battle of the 2019 Solheim Cup

One of the most significant and/or prevalent symbols of nationhood is to be found in the international (men's) sporting arena. Sport is often imbued with notions of national identity and war, although the sport of golf is generally devoid of flags and nationalistic tendencies and is thus often considered relatively insignificant in inculcating national sentiments – except in the exceptional cases of team golf events such as the Solheim Cup. This paper considers the way in which the competitors in the 2019 Solheim Cup were represented in the British print media. Results highlights that national identity is a key descriptor of the female competitors, legitimising their position in the battlefield of international sport. We conclude that, in an era of increasing significance of women's sport, there exists an ideological space for women to be seen as 'proxy warriors' in sport

Sport for Yes? The role of sporting issues in pro-independence political discourse during the Scottish independence referendum campaign

This article critically considers the extent to which sporting issues were harnessed by pro-independence political campaigners during the Scottish independence referendum campaign. Developments such as the inclusion of sport within the Scottish Government’s White Paper on Scottish independence, the establishment of the ‘Working Group on Scottish Sport’ and the establishment of the ‘Sport for Yes’ campaign group demonstrate the harnessing of sporting issues as an additional, if somewhat peripheral, debate point in the referendum campaigns (Lafferty 2014, Scottish Government 2013, Working Group on Scottish Sport and Scottish Government 2013, 2014). The latter of these developments, the establishment of the ‘Sport for Yes’ campaign group, is of particular interest, offering evidence of the explicit political mobilisation of past and present athletes in support of the ‘Yes Scotland’ pro-independence campaign. The use of sport within pro-independence political discourse is therefore scrutinised, drawing upon the principles of critical discourse analysis to explore the ideological assumptions underpinning the discursive representation of sport in relation to Scottish independence
