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

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

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

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

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 Commit to Be Fit framework: a community case study of a multi-level, holistic school-based wellness initiative in rural Virginia

BackgroundPublic health interventions that target children's physical, mental, and emotional health will enhance their ability to learn and grow. Although more complex, school initiatives that address multiple ecological levels and take a holistic view may be more effective and likely to lead to lasting change.AimsThis article presents the framework of Commit to Be Fit (C2BF) as an example of how schools can integrate multi-level and holistic approaches for health. This innovative school-based intervention includes activities addressing individual, home, school, and community to create a culture of wellness. We describe the implementation of C2BF and its basis in ecological models and give examples of activities across three components: cafeteria, classroom, and community. We discuss challenges and note that leadership engagement and alignment were critical elements for C2BF's success thus far.DiscussionC2BF uses a school-based multi-level approach to creating a culture of wellness and holistic health for students, teachers, and community members. C2BF is unique compared to other school-based programming and includes activities that address all eight domains posited for program sustainability within public health. Built to be flexible and adaptive, C2BF was able to successfully pivot during the COVID pandemic and also follow new science.ConclusionC2BF and other multi-level holistic approaches are more likely to achieve long-term change by utilizing strategies across the multiple levels of the ecological model to improve health and wellbeing

Elevated circulating and placental SPINT2 is associated with placental dysfunction

Biomarkers for placental dysfunction are currently lacking. We recently identified SPINT1 as a novel biomarker; SPINT2 is a functionally related placental protease inhibitor. This study aimed to characterise SPINT2 expression in placental insufficiency. Circulating SPINT2 was assessed in three prospective cohorts, collected at the following: (1) term delivery (n = 227), (2) 36 weeks (n = 364), and (3) 24–34 weeks’ (n = 294) gestation. SPINT2 was also measured in the plasma and placentas of women with established placental disease at preterm (p = 0.028; median = 2233 pg/mL vs. controls, median = 1644 pg/mL), or delivered a small-for-gestational-age infant (p = 0.002; median = 2109 pg/mL vs. controls, median = 1614 pg/mL). SPINT2 was elevated in the placentas of patients who required delivery for preterm preeclampsia (p = 0.025). Though inflammatory cytokines had no effect, hypoxia increased SPINT2 in cytotrophoblast stem cells, and its expression was elevated in the placental labyrinth of growth-restricted rats. These findings suggest elevated SPINT2 is associated with placental insufficiency

‘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’

Cosmopolitan Species As Models for Ecophysiological Responses to Global Change: The Common Reed \u3cem\u3ePhragmites australis\u3c/em\u3e

Phragmites australis is a cosmopolitan grass and often the dominant species in the ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P. australis has an extensive ecological amplitude and a great capacity to acclimate to adverse environmental conditions; it can therefore offer valuable insights into plant responses to global change. Here we review the ecology and ecophysiology of prominent P. australis lineages and their responses to multiple forms of global change. Key findings of our review are that: (1) P. australis lineages are well-adapted to regions of their phylogeographic origin and therefore respond differently to changes in climatic conditions such as temperature or atmospheric CO2; (2) each lineage consists of populations that may occur in geographically different habitats and contain multiple genotypes; (3) the phenotypic plasticity of functional and fitness-related traits of a genotype determine the responses to global change factors; (4) genotypes with high plasticity to environmental drivers may acclimate or even vastly expand their ranges, genotypes of medium plasticity must acclimate or experience range-shifts, and those with low plasticity may face local extinction; (5) responses to ancillary types of global change, like shifting levels of soil salinity, flooding, and drought, are not consistent within lineages and depend on adaptation of individual genotypes. These patterns suggest that the diverse lineages of P. australis will undergo intense selective pressure in the face of global change such that the distributions and interactions of co-occurring lineages, as well as those of genotypes within-lineages, are very likely to be altered. We propose that the strong latitudinal clines within and between P. australis lineages can be a useful tool for predicting plant responses to climate change in general and present a conceptual framework for using P. australis lineages to predict plant responses to global change and its consequences
