Hill College West Research Forum 2015 Talk Abstracts 2 Hill College West Research Forum 2015 Leprosy and the Religious Significance of the 9-Banded Armadillo Cameron Clegg, PhD in the Department of Archaeology, St Aidan’s College Abstract:Leper. Even today the term conjures up horrific images, rife with religious sentiment and social stigma. Leprosy, or Hansen’s disease, is still present today, and has been known since 2000 B.C. The 19th and 20th Century saw the organised banishment and segregation of lepers, ostensibly to protect the uninfected from a communicable disease. The social stigma that this disease carried was affiliated with religious blight, and persists to this day. What are the origins of this stigma? Why is it still important today? And, most importantly: What does any of this have to do with the 9 banded armadillo? How could this adorable little creature be at the centre of ending this centuries-old stigma? This talk will examine this disease, explore the origins of the social stigma associated with it, and expose the significance of one of the oldest extant mammalian orders on this earth. 3 Hill College West Research Forum 2015 The drivers of inter-annual variation in the terminus position of outlet glaciers in East Antarctica Arminel Lovell, MSc by Research in the Department of Geography, Van Mildert College Abstract: Outlet glaciers in the Greenland and West Antarctic Ice Sheets are rapidly losing mass, increasing ice-sheet contribution to global sea-level. The East Antarctic Ice Sheet (EAIS) is considered to be more stable and has therefore received less attention from researchers. However, recent research has suggested that outlet glaciers in large parts of the EAIS are more vulnerable to climatic forcing than previously acknowledged. Therefore a better understanding of the drivers of outlet glacier behaviour in the EAIS is needed. This project investigates and compares the recent terminus changes of outlet glaciers in three distinct climatic regions (Victoria Land, Oates Land and George V Land) in East Antarctica in order to identify the recent regional and glacier-specific controls on their terminus position at inter-annual time-scales. Terminus change was calculated for 134 glaciers in the study area at 4-year intervals between 1997 and 2013. The relationships between glacier terminus change and potential forcing mechanisms including air temperature, sea-surface temperatures and ice velocity were investigated. The role of glacier-specific factors such as fjord width and shape and terminus type (land- or marine-terminating) in modulating glacier terminus behaviour was also studied. Initial results show a general trend of glacier advance in all three regions over the past 20 years. However, land-terminating glaciers show minimal variation in comparison with marine-terminating glaciers suggesting that glacier-specific factors may also have an important role to play in outlet glacier behaviour. 4 Hill College West Research Forum 2015 A glimpse into the world of particle physics Gilberto Tetlalmatzi, PhD in the Department of Physics, St Aidan’s College Abstract: Our understanding of the fundamental structure of matter changed drastically in the last century, indeed the development of quantum mechanics allowed to transform our vision of the microscopic world, starting with the description of the basic components of nature in terms of atoms and ending with the construction of the Standard Model of Particle Physics: a very successful theory for studying the interactions of subatomic particles. The experimental evidence in favour of the Standard Model is impressive as it has been verified by different high energy physics experiments such as the Large Hadron Collider (LHC) . One of the most recent proofs of the validity of this theory is the discovery of the Higgs boson in 2012, introduced theoretically since the 1960's. However there are still some conceptual and observational problems that cannot be addressed within the realm of the Standard Model, for instance the existence of dark matter or the asymmetry between matter and antimatter in the universe. This year the LHC is running again at energies not previously achieved by any of the high energy physics experiments constructed until now with the expectation of discovering new particles or forces that can explain some of the open questions mentioned previously. The purpose of this non technical and self contained talk is to give an introduction to the ideas behind the Standard Model of Particle Physics, such as the physics of subatomic scales (Quantum Mechanics) and the physics of bodies moving near to the speed of light (Special Relativity). The structure of the model will be discussed to conclude with an explanation of some of its possible extensions and challenges. 5 Hill College West Research Forum 2015 A threaten or an opportunity for international financial market? The necessity to regulate sovereign wealth funds investment Wei Yin, PhD in the Department of Law School, Trevelyan College Abstract: Sovereign wealth funds (SWFs), as a long-term investor, have not had widespread attention, until the outbreak of global financial crisis, during which time they invest into global financial market. With rapid development and increasing asset accumulation, SWFs have become influential investors worldwide while their sovereignty and lack of transparency raised concerns from developed countries. They worry that if SWFs investment were lack of supervision and regulation, they would shake the stabilization of global market and threaten the national security of host countries. Therefore, developed countries claim that SWFs should be regulated. However, different countries have different legal culture and legal system, it is unreasonable to ask SWFs to abide by every regulation of host countries. Therefore, why are the problems about SWFs? Why should SWFs be regulated? Which type of regulation is suitable to regulate them? To analyse these issues, my presentation will firstly section talk about the nature of sovereign wealth funds, especially its definition and its role in international finance and investment market. Secondly, the influences of sovereign wealth funds and concerns caused by their activities. Thirdly, I will talk about the regulation per se and explain the reasons why they should be regulated from both practical and theoretical support. Finally, I will elaborate the important of the suitable regulation for national and international financial market. 6 Hill College West Research Forum 2015 Poster Abstracts 7 Hill College West Research Forum 2015 Density dependent pollinator behaviour influences plant success Natalie Allum, MSc by Research in the Department of Ecology, Trevelyan College Plant-pollinator interactions are common examples of service-resource mutualisms. However, the efficiency of the relationship seems to be context-dependent. Pollen limitation is a common restraint on seed development, and because this seems to be more frequent in smaller populations it has been suggested that plants are more attractive at higher densities. Assuming that this is true, the changes in attraction should lead to changes in the per-flower visitation rate. These changes could be positive, negative or neutral. Using a simulation model I have looked at the growth and expansion of a population of bluebells (Hyacinthoides non-scripta) over 200 years, under the influence of positive or negative effects of density on fertilisation. Pollinator foraging behaviour is an important determinant of plant density and the proportion of plants flowering, but has less effect on the rate of population spread. This work has demonstrated the importance of knowing the true relation between flower density and fertilisation success for bluebells. 8 Hill College West Research Forum 2015 Human Skeletal Remains Cameron Clegg, PhD in the Department of Archaeology, St Aidan’s College This poster will provide a general introduction for the archaeological analysis of human remains. The poster explores the various methods by which human bones are used to estimate the age and sex of individuals, as well as how disease and injury affected them. Palaeopathology: Skeletons From Durham Market Place Cameron Clegg, PhD in the Department of Archaeology, St Aidan’s College This poster follows the one above, providing a case study for the above analyses. The poster explores the lives of individuals living in Medieval Durham, investigating how their day-to-day lives were affected by injury and disease. Zooarchaeology Cameron Clegg, PhD in the Department of Archaeology, St Aidan’s College This poster gives a general overview of how the analysis of animal remains recovered from archaeological sites can shed light on the lives and occupations of past peoples. Specifically, it looks at what animal remains can reveal concerning the diet of people as well as the presence of trade or craft industries. The Bones at Binchester: A Zooarchaeological Analysis of Cattle from a Late Roman Military Fort and Civilian Settlement in Northern England Cameron Clegg, PhD in the Department of Archaeology, St Aidan’s College Analysis of cattle bones recovered from archaeological sites can give us insight into various exploitation strategies employed by past peoples. Located near Bishop Auckland, co. Durham, the site of Binchester, Roman Fort was built to house cavalry in AD 80, and saw continued occupation throughout the Roman period. Being the subject of many previous excavations, the current project at Binchester started in 2009, with trenches open in both the military fort and the neighboring civilian settlement. With cattle representing 70% of the recovered identifiable fragments, Binchester, Roman Fort provides an excellent opportunity to examine the utilization of cattle as a source of sustenance, labor, and other secondary products. Through a detailed morphometric analysis of the cattle bone recovered from Binchester we can gain insight into the specific practices and strategies employed by the inhabitants of the sight, both military and civilian, and further enhance our understanding of Roman animal husbandry within the greater research context of Late Roman Britain. 9 Hill College West Research Forum 2015 A threaten or an opportunity for international financial market? The necessity to regulate sovereign wealth funds investment Wei Yin, PhD in the Department of Law School, Trevelyan College Sovereign wealth funds are usually regarded as assets owned or managed by general government but separate from official foreign reserve in pursuit of macroeconomic purpose and high-returned profits. As long-term investing entities, sovereign wealth funds have attracted wide attention since the outbreak of global financial crisis. However, the rapid development of them also lead to concerns so that developed countries call for regulations especially restrictions on SWFs. On the other hand, international community recognizes that sovereign wealth funds indeed bring benefits to current international financial market. Therefore, the question may occur: why do the sovereign wealth funds need to be regulated? This poster will demonstrate the definition of sovereign wealth funds, the influences of their activities from both positive and negative aspects and then analyses the necessity to regulate them according to practical issues and theoretical underpinnings. Orientation: Section 1: What are sovereign wealth funds? a. Definition in economy and law literature b. Proposed definition Section 2: what are the influences and issues of sovereign wealth funds investment? a. Influences of sovereign wealth funds development b. Concerns to sovereign wealth funds investment Section 3: Why do sovereign wealth funds need to be regulated? a. Practical consideration b. Theoretical analysis Section4: What kind of regulation is needed? a. A general regulation or special regulation for sovereign wealth funds? b. What is the problem if over-regulated 10
