SHOWCASE 2012 The third annual University of Leeds Postgraduate Researcher Conference 3rd December 2012 Postgraduate Researcher of the Year Abstracts and Impact Statements Phillipa Coan Leeds University Business School Abstract Climate change is arguably the most significant global challenge of the 21st century with substantial consequences to our ecosystems, human health, economy and ultimately the survival of our planet. There is now increasing evidence that human activities are responsible for most, if not all, of the recent changes in climate. Subsequently, targeting individual behaviour is imperative if we are to meet our increasingly ambitious carbon targets. Research to date has primarily focused on promoting environmental behaviour in the home, despite the fact that industry accounts for a far greater proportion of energy, waste and water usage (Eurostat, 2010). Furthermore, there is almost no empirical research at all exploring environmental behaviour between the workplace and the home. This research subsequently sets out to explore how best to change employee behaviour to be more environmentally sustainable; more specifically it investigates the relationship between environmental behaviours carried out at work and at home (known as ‘spillover’) with the intention of encouraging a stronger link between the two. Four major organisations in manufacturing, oil and gas, engineering and government are participating in this research. Using a mixed methods approach, over a 6-month period, initial findings have revealed a significant spillover effect with a number of individual and group factors (e.g., values, attitudes, identity and norms) leading to environmental behaviours at work but only if these same behaviours are carried out at home. These early findings are pointing to new directions for how to successfully promote more consistent environmentally sustainable lifestyles across multiple social contexts. Impact Statement This will be one of the first pieces of empirical work investigating the spillover of environmental behaviours between the work and home domains. By linking two areas of research that previously were treated separately, this research fills a critical gap in the literature opening up exciting new challenges and opportunities for academic enquiry. My initial findings have highlighted the importance of considering home behaviours alongside work behaviours when designing workplace environmental initiatives to ensure they have an extended positive impact. This work has subsequently already started to impact the participating organisations by increasing understanding around these issues and triggering new strategies that will capitalise on the findings. My research so far has captured the interest of a large multinational car manufacturing company who are keen to integrate my findings to improve an existing environmental programme. Likewise the participating oil and gas company want to extend my work to Denmark and Qatar to explore cross-cultural implications. I am also currently in discussions with the Department of Energy and Climate Change and the Department for the Environment, Food and Rural Affairs about my research. My findings could therefore play a key role in developing government policy for how organisations can further reduce their negative impact on the environment beyond current legislative targets. I have presented my work locally at a number of Leeds University conferences (2nd prize Best Presentation, 2011), nationally at the British Psychological Society’s Going-Green Working Group (GGWG) Conference, as well as internationally to a Worldwide Universities Network (WUN; comprising 9 universities and 12 companies across 7 countries) who focus on promoting ‘green’ behaviour at work. Through my membership of the GGWG and WUN, I also attend regular meetings using my research to extend knowledge, contribute towards future directions in the field and encourage others to consider this research area. Maya Parmar Faculty of Arts Abstract Fully funded by the Joseph Wright Scholarship, my doctoral research considers how cultural identity is represented amongst the twice displaced Gujarati East African community in Britain. Long settled in Kenya, Uganda or Tanzania, this community, who migrated from India, were eventually compelled to leave their established homes in East Africa for a life elsewhere. It is those ‘twice migrants’ that came to Britain, and often become hidden amongst the larger South Asian diaspora, which my research reflects upon. There is a lacuna in literary representation produced by, or about, this diaspora: the Gujarati East African in Britain has no White Teeth or Brick Lane. My research subsequently considers the other forms of ‘texts’ the diaspora favour in self and collective representation, broadening the understanding of what is a readable ‘text’, within literary studies. Looking beyond the traditional written text, I analyse culinary practices (food), dance rituals and visual material (photographs). My thesis is, as a result, multidisciplinary in its methodology. I have presented my research both in the UK and abroad: As well as presenting at the Institute for Colonial and Postcolonial Studies Annual Conference (September 2010), and the Centre for Research on Nationalism, Ethnicity and Multiculturalism Annual Conference (June 2011), in February 2012 I spoke at the Gujarat Studies Association (GSA) Biennial Conference, in Dubai (funded by a GSA bursary, Leeds for Life and The School of English Conference Grant). Impact Statement Whilst broadening literary studies to consider diverse ‘texts’, my research aims to nuance diasporic studies by explicating the multiple axes that migration exists upon. There remains an artificial understanding of migration as linear; however, my research adds specificity to this perception. Recently I spearheaded the “impact” project Expulsion: 40 Years On, for which I raised £12,898. This outreach work, marking the 40th anniversary of the South Asian expulsion from Uganda by Idi Amin, developed from my research. The project, during summer 2012, incorporated two elements: local primary school workshops on migration, dance and identity; and a colourful participatory cultural, community day event at Leeds City Museum (LCM). Having won University of Leeds funding (Higher Education Innovation Fund, Arts Engaged and Leeds for Life), I successfully wrote a bid for the coveted Grant for Arts, Arts Council England. Via this project, which had several partners, ample publicity was secured: radio appearances, a Yorkshire Evening Post article, and online listings and features. I was also invited to participate in a panel discussion of the 2012 South Asian Literature Festival. By invitation again, I have submitted a peer-reviewed article to the journal South Asian Popular Culture. I will present at the Arts and Humanities Research Council and University of Southampton’s Knowledge Exchange and Arts and Humanities Research Conference, July 2013. I am also a member of the GSA, a freelance learning coordinator at Temple Newsam House, and am on the advisory network of LCM’s Voices of Asia Exhibition. For the Re-evaluating the Postcolonial City Conference 2012 I co-assembled a conference team and led us to secure £1000 external funding, and the international author Caryl Phillips as keynote speaker. Having successfully co-proposed a Special Issue to the renowned journal Interventions to publish selected conference proceedings, I am now on the Special Issue editorial team. Matthew Fuller Faculty of Performance, Visual Arts and Communication Abstract Duck and goose down feathers are incredible materials that are poorly understood. Down is the under-feathers of waterfowl, and has a better warmth-to-weight ratio than any other fibrous insulation, far surpassing the performance of man-made materials. Though also used in luxury bedding, down is most important to mountaineers, who rely on lightweight down sleeping bags and clothing. Work with an industrial partner has produced a range of down sleeping bags that have been designed based on extensive experimental research. These new sleeping bags are much-improved (greater warmth to weight ratio) and offer world-leading performance. Down’s Achilles heel is that it clumps together when wet, losing much of its insulating performance. As a result, water-resistant treatments have become available, and three of these have been compared to untreated down samples. Though the water-resistant treatments were found to increase down’s resistance to water, they were still flawed. There are many undiscovered areas in the fundamentals of down’s properties. By studying down’s physical, chemical, and mechanical attributes, further work will determine why down’s insulating performance is so impressive, why its performance is affected by water, and whether synthetic down alternatives could be developed that would improve on down’s performance. Impact Statement Despite its outstanding thermal properties there have been very few academic studies into down, particularly when compared to the mass of work carried out on cotton and wool fibres. Detailed research into down will ensure that it is fully-understood by the outdoor and bedding industries and aims to initiate the use of this amazing natural material in new applications, including in biodegradable filters. Without this fundamental research, down’s incredible properties will never be completely utilised or appreciated. This work has already been recognised by members of the outdoor industry as very valuable. The relatively small budgets of companies in the industry means that rigorous scientific research is often overlooked in favour of estimation and conjecture. This project has proven that experimental evidence and thorough study can produce excellent results even when applied to complex products such as sleeping bags. This could go-on to produce a welcome change in mind-set in the industry. The sleeping bags developed in this project offer exceptional performance and have given better advance sales than any previous range. As a result of my research I am now a member of the Down Task Force, an international working group of approximately 80 members from all parts of the outdoor industry. The group aims to overcome ethical problems in the supply of down. It is the first group of its kind in the multi-billion dollar outdoor industry and has become a model on which other traceability and sustainability groups are being based. I am passionate about educating non-specialists about down and performance clothing. To this end I have written two articles for Europe’s largest outdoors website; the first article has received over 20,000 unique views. These articles have received acclaim from both industry and consumers and have empowered many people with detailed knowledge that is not available elsewhere. Catherine Scott Faculty of Environment Abstract It is well understood that trees take in carbon and store it as they grow, but far less certain is their role in the formation and growth of microscopic particles in the atmosphere. Trees constantly emit gases into the atmosphere that are quickly converted into a more complex form, enabling the gases to stick to particles and change the particles’ properties, or potentially form new ones. Particles in the atmosphere are of crucial importance to the climate because they control the amount of energy from the Sun that reaches the Earth’s surface by absorbing or scattering the energy, and by influencing the brightness of clouds. Only certain types of particles can form cloud droplets; but where there are more particles, the clouds are brighter and reflect more energy back to space, resulting in a cooling of the Earth’s surface. The build-up of greenhouse gases (GHGs) in the atmosphere is driving an increase in global temperatures which will continue until GHG emissions cease. Deforestation contributes approximately 10% of GHG emissions, but may also be responsible for additional warming if it has led to a reduction in particles able to cool the planet by scattering energy or brightening clouds. My research uses detailed computer simulations to represent the interactions between trees and the atmosphere. By examining the role that forests play in the climate system I have shown that reducing deforestation is even more important than previously thought and am now investigating to what extent planting new trees could help to mitigate climate change. Impact Statement Finding a workable solution to climate change is the greatest challenge facing our generation. Continued emission of greenhouse gases will lead to further global temperature increases, sea level rise and more extreme weather events; placing much of the world’s population at risk of drought, flooding and famine. To find a solution, we need to fully understand how natural systems control the climate, and how human activities are interfering with that control. The fact that molecules emitted by plants are manipulating the reflectivity of the atmosphere fundamentally alters our perception of the role of forests within the Earth system. Without this research, it will not be possible to appreciate the impacts of deforestation or to accurately assess the relative merits of planting new trees in different parts of the world. I have presented my work at several international conferences, been interviewed for the NERC Planet Earth Online podcast, and will shortly be publishing my findings in a peer reviewed journal. Alongside my research, I volunteer for the United Bank of Carbon (UBoC), which is a non-profit collaboration between business people and academics from the University of Leeds. UBoC is a registered charity, relying on volunteer effort to attract funding for rainforest protection projects in the tropics. We rigorously screen the projects so that we only seek funding for those that are able to offer community and biodiversity benefits, alongside forest conservation. My role is to write detailed project descriptions for the UBoC website, contribute regular blog posts, meet with project coordinators and maintain the UBoC social media pages. At the moment I’m helping to set up a partnership between the University of Leeds and two community-conservation projects in Africa, through which staff and students at the University will be able to offset their carbon emissions from any unavoidable work related travel. Natalie Hirst Faculty of Biological Sciences Abstract Over 55,000 people are diagnosed with bowel cancer each year in the UK. Treatment almost always requires surgical removal of a section of bowel, requiring the loose ends to be re-joined to restore continuity. Leakage of bowel contents from the join site (known as an anastomosis) is a catastrophic surgical complication occurring in up to one-third of cases, resulting in grossly increased risk of death and infective complications. Delay in diagnosis of anastomotic leak correlates directly with poorer patient outcomes, yet current diagnostic tests are few, insensitive and costly. The most recognised type of biosensor is a glucose sensor used by diabetics to measure blood sugar. A biosensor as a diagnostic test for anastomotic leak would give immediate and accurate results, quickly and cheaply. My research is developing a series of biosensors for detection of anastomotic leak, by measurement of specific indicators within patients’ abdominal fluid which drains out from a tube placed at operation. The indicators include lactate - signifying inadequate blood supply to the anastomosis inflammatory cells, and bacteria. My work has successfully generated a working lactate biosensor. I optimised the method of sensor construction by testing in artificial solutions, before using patient drain fluid I collected from bowel surgery patients. The results from my sensor match up with those of a commercial lactate measurement kit, demonstrating that the sensor would work as a test for detecting bowel leak. I am constructing two further biosensors, and the best one will be put forward to commercial clinical application. Impact Statement I successfully secured two competitive funding awards for my work to the sum of £118,000, from the Bowel Disease Research Foundation, and the Leeds Teaching Hospitals NHS Trust Charitable Foundation. I have generated a lactate biosensor which works on real patient samples. When developed further as a clinical application, this has the potential to save countless lives, as well as greatly reduce other problems from anastomotic complications. The biosensor could also pick up other life-threatening abdominal disorders such as organ inflammation; therefore the benefits are potentially extensive. The cost of a bowel operation increases by at least £30,000 if anastomotic leak develops. The cost of intensive care unit stays and management of subsequent multi-organ failure also adds to the economic burden and use of hospital resources. Biosensors are renowned for being low cost. The financial impact of my research is potentially vast, in radically reducing the need for expensive, prolonged hospital care. I have given oral presentations of my research at a number of national and international meetings including a colorectal cancer research workshop in Leeds and a clinical biosensing conference in Rome. I presented at a steering group collaboration between the Northern and Yorkshire medical deaneries in addressing the need to reduce anastomotic leak rates and outcomes. I have authored a paper due for submission in the highest impact peer reviewed journal of biosensing: “Biosensors and Bioelectronics”. I am currently co-writing a press release for this article, to further increase awareness and public knowledge of my research. Public engagement to demystify scientific research is something I feel passionately about. I have recorded a video podcast explaining my research work, which will be made publically available on the University faculty website. I am an active member of Athena SWAN, a national initiative to encourage gender equality in science and research. Sam Pickard Faculty of Engineering Abstract Driven by our continuing hunger for energy we have burnt fossil fuels and released billions of tonnes of greenhouse gases (GHGs) into the atmosphere, changing our planet's climate and endangering the wellbeing of all future generations. Most UK electricity is produced by fossil-fuelled power stations which, built by decades of innovation and investment, continue to represent one of the cheapest and most reliable ways to deliver power to our homes and businesses. Alongside developing truly sustainable alternatives to replace them, we must move to reduce the environmental impact, particularly GHG emissions, of such plants. Substituting fossil fuels with sustainable sources and capturing the GHGs produced, preventing their escape to the atmosphere, are two leading options. My research looks at combining these technology options by substituting coal with sustainable biomass and burning the fuels in a way which makes it easier to capture the main GHG (carbon dioxide) ready for permanent storage deep underground. More specifically I work in three areas. In the laboratory I try to better understand how the reactivity of different biomass fuels changes in unconventional combustion scenarios. I then test these fuels and scenarios in a scaled, pilot furnace to investigate how the combustion process may proceed in a real power plant. Appreciating the wider context I also analyse how factors other than technology (such as knowledge transfer gaps, a lack of skilled people, poorly executed regulation, political pressures etc.) may hamper the required development of these technologies in the future. Impact Statement I've presented my work to national or international academic and industrial audiences at 9 conferences, workshops and meetings (6 oral presentations, 5 posters) and at the World Resources Forum in Beijing my work was selected as one of the research highlights in the closing session. I'm writing up the work presented at these events and currently have one journal paper submitted for review, two which I hope to submit before the end of 2012 and another by spring 2013. During a placement with the government I contributed to the research and development chapter of the UK CCS Roadmap (2012) and the 'RD&D Themes and Priorities' matrix in the Advanced Power Generation Technology Forum publication (2011). Outside my field, I have engaged about the wider context of my work with a range of audiences including school children as an Ogden Fellow, muddy ravers at Green Man music festival, the general public at the British Science Festival and with civil servants at a dedicated meeting in Whitehall. In addition to completing a placement on site, I was selected as the Student Representative for UoL at the launch of the CCPilot100+ programme and, as publicised by the UK CCS Network, met and explained a part of the process to the then Secretary of State for the Department of Energy and Climate Change. I am currently on the return leg of travelling to and from conferences in China and Japan without flying in an attempt to quantify whether alternative methods of transport and lifestyle could reduce our environmental impact and highlight behavioural change possibilities. During this I maintain a blog which has had nearly 2000 views and secured me interviews with the conference organisers in Japan and Student Reporters in Beijing as well as a degree of notoriety as 'the train boy' at both conferences. Gordon Clubb Faculty of Education, Social Sciences and Law Abstract My research is concerned with how terrorist campaigns end with a reduced risk of violence reemerging. Previous research has focused on groups or individuals engaged in terrorism, whilst the society they emerge from is treated as a static entity – in other words, it isn’t clear what is happening in society when groups/individuals are disengaging from terrorist activities). The main problem with this approach is it encourages counter-terrorist strategies that focus on ending terrorist behaviour rather than broader social change. Thus, the decline of terrorism is disconnected from their real causes and so strategies of coercion or short-term fixes are emphasised. I look at the case of Northern Ireland to analyse how the decline of terrorist campaigns can be made to be more durable: this is referred to as social disengagement. Since the Provisional Irish Republican Army’s full disengagement (2008), terrorist violence has been on the increase. My research explores the extent there has been social change in terms of the causes of the conflict in the 1960s and nowadays, using social movement theories to help outline the durability of disengagement. I will conduct fieldwork in Northern Ireland which will explore the extent attitudes and behaviour has changed in communities, specifically amongst younger generations, and the extent the peace process has impacted them, whether it has alienated them and if they are at risk of joining militant groups. The research will provide better predictors of recidivism at a social level, helping to inform social approaches to countering terrorism. Impact Statement I have established an international organisation of 120 Terrorism researchers known as the Terrorism and Political Violence Association (TAPVA). I have built partnerships with think-tanks, such as Foreign Policy Centre and Royal United Services Institute, raised £50,000, and have collaborated with policy-makers and researchers, such as Foreign Office’s counter-terrorism unit. By bringing together different partners and drawing on resources, I have: organised a workshop in March, 2012 that brought together academics and policy-makers, with a lecture from an advisor to President G.W. Bush; began organising an international conference in November, 2012 in partnership with RUSI which has already attracted leading international academics and major policymakers. By bringing academics and non-academics together, I have facilitated knowledge exchange and direct impact. I have also facilitated other forms of research: TAPVA’s research has been used in the Foreign Affairs Select Committee and I am editing a policy document in conjunction with the Institute for Strategic Dialogue which is driven by the research demands of policy-makers, then disseminated to them in a digestible manner. Furthermore, I am conducting a survey and interviews on the relations between the academic and policy-maker community and mutually identified research gaps. No such study exists and the potential impact it will have on both communities is immense: first, it will define common areas for collaboration and research for the next few years; second, it will enhance our understanding of impact, showing the mechanisms to blur the distinction between the two communities. I have discussed the role of prisoners in disengagement processes with the Home Office and TAPVA acts as a conduit to feed the findings of my research to this community. In addition to conducting highimpact research on Northern Ireland, my book on Hizbollah will be aimed at policy-makers by concisely analysing the group from a practical approach. Gordon Hutchins Faculty of Medicine and Health Abstract In the United Kingdom each day, 100 people are diagnosed with and 43 will die from bowel cancer. Treatment depends on how far the cancer has spread. If contained within the bowel wall (stage I), surgery is curative; where tumour has spread to lymph nodes (stage III), post-surgery chemotherapy (adjuvant chemotherapy) improves survival. Unfortunately, over 1/3 of patients have tumours extending beyond the bowel that do not involve lymph nodes (stage II). In these individuals, adjuvant chemotherapy is controversial; treating 100 cures just 3. Consequently, only those of high recurrence risk (RR) are given chemotherapy. Identifying them is difficult and, because of modest treatment effects, most do not benefit. There is, therefore, an urgent need to better categorise stage II patients in terms of RR (using prognostic markers) and response to chemotherapy (predictive markers) to avoid inappropriate treatment. These core principals form the basis of my research. Molecular/morphometric analyses were performed on 1900 samples from a large stage II bowel cancer trial. Multiple prognostic biomarkers (to predict RR) were defined/validated including cell proliferation markers, mismatch repair (dMMR) status and tumour-stomal analysis (TSA). Of note dMMR and TSA reliably stratified patients into groups of high/low RR. Such stratification can aid the selection of patients for chemotherapy. Unexpectedly, TSA may also identify tumours that better respond to chemotherapy. This research has identified simple biomarkers that may improve management of stage II bowel cancer by accurately selecting patients for chemotherapy (by RR or response). In doing so unnecessary treatment can be avoided. Impact Statement As stage II bowel cancer represents 1/3 of all bowel cancer diagnoses, this work is of critical importance both nationally and globally in improving the treatment of stage II bowel cancer patients. By more accurately selecting patients for chemotherapy, unnecessary toxicity, cost and patient inconvenience can be avoided. The work in defining and validating mismatch repair status as a simple and reproducible prognostic marker in order to predict recurrence risk has contributed to policy changes in molecular testing strategies across the world, particularly as this work represents the largest published study of mismatch repair status in stage II cancer. Consequently, partly as a result of this work, routine mismatch repair testing has been introduced in the United States and many parts of Europe. The policy is currently under evaluation in the United Kingdom. The stage II bowel cancer mismatch repair work has been published in the Journal of Clinical Oncology (Hutchins et al, J Clin Oncol. 2011. 29(10):1261-70), a journal of impact factor of 18.97. The paper has been cited 27 times to date and has been selected for the F1000 prime library (f1000.com/prime), placing it in the top 2% of published articles in biology and medicine. The mismatch repair data has additionally been presented at national and international conferences including the American Society of Clinical Oncology, Chicago, where the abstract was selected for a prestigious poster discussion symposium. Press coverage for the work has included the Yorkshire Post amongst others. The tumour-stroma analysis work is on-going, but is providing fascinating insights into tumour biology. This simple morphometric analysis has the potential not only to stratify bowel cancer patients into high/intermediate and low recurrence risk groups but may even predict which ones will respond to chemotherapy. Because unexpected, careful interpretation of predictive capacity is required and further investigations are on-going. James Towey Faculty of Mathematics and Physical Sciences Abstract Cryopreservation is a process in which biological materials, from small molecules to whole tissues, are stored and conserved at sub-zero temperatures, and is used widely in industry, medicine and nanotechnology. Cryopreservation is made possible by molecules called cryoprotectants, such as glycerol. Despite this being a well-known and often used technique, the molecular mechanisms of cryopreservation are not yet understood. Historically, theories aimed at explaining the action of glycerol centre around changes in the structure and hydrogen bonding of water. I use state-of-theart equipment at the ISIS pulsed neutron facility within the Rutherford Appleton Laboratories to complete structural studies of glycerol-water mixtures at a range of temperatures. This allows me to obtain a full atomistic-level description of aqueous glycerol from experiment, and thus test theories of cryorprotective action. It was previously proposed that glycerol lowers the number of hydrogen bonds that water molecules are able to form. I have tested this hypothesis and shown that it is incorrect. Glycerol does not diminish the hydrogen bonding ability of water. Instead, water forms hydrogen bonds with glycerol that compensate for the loss of bonds to other water molecules. In addition, glycerol imposes micro-segregation, resulting in clusters of water molecules and glycerol molecules. This results in an interconnected network of water and glycerol hydrogen bonded clusters. These results have allowed me to propose a new hypothesis for the cryoprotective action of glycerol, in which extended water networks are inhibited, due to the presence of an interconnected water-and glycerol network, thus preventing ice formation. Impact Statement My PhD research has tested and disproved a hypothesis for the cryoprotective action of glycerol. Through an extensive series of experiments, I have proposed a new hypothesis for the molecular mechanism of cryopreservation. This has resulted in three first author publications, one of which was featured on the cover of Journal of Physical Chemistry B. My research is important because hydrogen bonded liquids are of significant interest to many scientists from molecular biologists to condensed matter physicists. The broad range of external audiences I have presented my work to highlights this. I have given oral presentations to the Society for Low Temperature Biology and the 32nd International Conference on Solution Chemistry as well as poster presentations at the Water and Aqueous Solutions Gordon Research Conference (GRC) and The Synthetic Components Network Annual Meeting. During my PhD I have been awarded prizes for the School of Physics best poster (2011), best oral presentation (2012), and bursaries from the GRC chair and the Institute of Physics to attend the GRC. My work has been reported in the Astbury Centre Annual Report of 2011, the ISIS Annual Review of 2012 (to be published) and was highlighted on the ISIS website. These reports are for a wide readership, from members of other academic disciplines to those working in industry. My research has also featured in the Scientific Technology and Facilities Council magazine for school children, Fascination. I have also written an article for Chemistry Review, a magazine for AS/A2 level chemistry students. I was co-chair of the Astbury Society Committee and, as such, was part of a team organising events focussed on forging new links between researchers across the University. I have also participated in face-to-face outreach by constructing and delivering a hands-on workshop on diffraction for secondary school children for the Smallpeice Foundation.
