Computational mechanistic studies of decamethyldizincocene formation and the enantioselective reactive nature of a chiral neutral zirconium amidate complex
Creators: name: Hepperle, Steven Scott
Publisher: name: University of British Columbia
Year: 2013

description: Computational methods were employed to study the surprising 2004 synthesis of de-camethyldizincocene, Zn2(η5−C5Me5)2, which was the first molecule to have a di- rect, unbridged bond between two first-row transition metals. The computational re- sults show that the methyl groups of decamethylzincocene, Zn(η5−C5Me5)(η1−C5Me5), affect the transition-state stability of its reaction with ZnEt2 (or ZnPh2) through steric hindrance, and this allows a counter-reaction, the homolytic dissociation of Zn(η5−C5Me5)(η1−C5Me5) into Zn(η5−C5Me5)• and (η1−C5Me5)• radicals to occur, and since no such steric hindrance exists when zincocene, Zn(η5−C5H5)(η1−C5H5), is used as a reactant, its dissociation never occurs. Experimentally, it was found that forming decamethyldizincocene is more efficient when using a reducing agent (e.g., KH) and ZnCl2 as opposed to a ZnR2 reagent. The computational results show that the methyl groups of decamethylzincocene have a similar indirect effect on the reaction. When zincocene is used, the reaction with KH favours the route that results in the formation of the zincate, K+[Zn(η1−C5H5)3]−. However, the path of formation for the zincate K+[Zn(η1−C5Me5)3]− is simply not favourable kinetically or hermodynamically, so the formation of decamethyldizincocene is the only option when Zn(η5−C5Me5)(η1−C5Me5)is used. Finally, it had been found that a particular chiral neutral zirconium amidate com- plex makes an effective catalyst for cyclizing primary aminoalkenes in a highly enan- tioselective fashion. The computational analysis indicates that the reason why one enantiomer is favoured is because of steric interference with the catalytic backbone that is non-existent with the other enantiomer, and this affects the major transition states throughout the cycle. This finding agrees with the experimental hypothesis.

description: In our paper we consider the notion of determinant of Clifford algebra elements. We present some new formulas for determinant of Clifford algebra elements for the cases of dimension 4 and 5. Also we consider the notion of trace of Clifford algebra elements. We use the generalization of the Pauli's theorem for 2 sets of elements that satisfy the main anticommutation conditions of Clifford algebra.

title: Nearlywriting nearlyology
Creators: name: Meade, C
Publisher: name: Bath Spa University
Year: 2018

description: Through contextual research and creative practice, this PhD explores the composition of fiction for today's mediatized society. Digital technology allows people to have multiple virtual personas, to be immersed in personalised media bubbles, to take one path but continue to keep an eye on the roads not taken; it also gives the writer new tools for mixing media and interacting with readers. Nearlywriting involves using whatever media and methods seem appropriate to convey a story, then seeking digital or analogue means to produce the results. The transmedia comic novel, What Didn't Quite, was created using this approach; a story about Nearlyology, exploring how things that people nearly do influence who they really are. Both components of the PhD explore how a transmedia literary fiction can convey the texture of everyday life and the inner lives of its characters while giving space to reader-generated responses and live collaboration. While scholarly writing on transmedia narrative and other related fields examines the potential for telling stories across different platforms and genres, how does the transmedia literary writer approach the production and publication of a multimodal text within the context of a complex publishing ecology? Contextual research uses the concerns of the novel's three protagonists to examine models of creation, distribution and performance of literary works. Concepts drawn from writing on transmedia narrative by Jenkins, Scolari and others are placed alongside insights from other fields relevant to multimodal composition; these include community arts, aboriginal storytelling, shamanism, outsider art, immersive theatre, psychotherapy, museum curation, songwriting and musical improvisation. Informed by McCluhan's analysis of the limiting impact of writing and print technology on the concept of literacy, Ingold's critique of academic writing which stands apart from the subject it explores and Solnit's comparison between writing and walking, this is a nearly conventional academic treatise, nearly a personal reflection on creative practice. Redrawing the boundaries of a book to include the total experience of time spent in and around its story world, What Didn't Quite includes songs, soundscapes, reader-generated stories, workshops, artworks and live performances as well as printed text.

description: The Arecibo Observatory 305 m radio telescope has been equipped with a seven feed Arecibo L-band Feed Array (ALFA) to convert the telescope into a multi-pixel imaging device. The off-axis nature of the six beams gives rise to asymmetric side-lobe patterns. The construction of an image by using the multi-beam data results in the presence of side-lobe artifacts in the image which are unique for each compact source depending upon the way the telescope scans across it. Removal of these side-lobe artifacts requires accurate models of the seven ALFA beams and a modification of the Hogbom CLEAN algorithm. This algorithm has been named multi-beam CLEAN and was developed and implemented using the Galactic ALFA Continuum Transit Survey (GALFACTS) precursor data-set. The results of the implementation were successful and have been used to CLEAN side-lobe artifacts from the precursor images.
title: The relationship between formative and summative teacher assessment of primary science in England
Creators: name: Earle, S
Publisher: name: Bath Spa University
Year: 2018

description: Assessment drives the taught curriculum, defines what is valued (Stobart 2008) and can enhance or hinder learning (Mansell et al. 2009). In England, the complexities of assessment are compounded by ongoing changes to statutory assessment procedures and a lack of centralised guidance for judgements of primary science (Turner et al. 2013). The Nuffield expert group (2012) proposed a pyramid-shaped model of teacher assessment which utilised formative information to inform summative judgements. The model was operationalised by the Teacher Assessment in Primary Science (TAPS) project (Davies et al. 2014), but there was no explicit explanation of the 'formative to summative' process. This study sought to develop understanding of the relationship between formative and summative teacher assessment of primary science, in action and over time. A Design-Based Research (DBR) approach was used in order to develop guidance directly relevant to practice. Analysis of 91 submissions from the Primary Science Quality Mark (PSQM) database provided a mapping of current practice in England. Two case studies of TAPS project schools considered the enacted relationship between formative and summative assessment, during implementation of a 'formative to summative' approach. New insights have been gained into the conceptualisation and enactment of the relationship between formative and summative assessment. Teacher conceptualisations of assessment were found to encapsulate a wide range of dimensions such as purpose, value, audience, assessor, timing, formality, rigidity and support. Refinements to the TAPS pyramid model are proposed to explain the 'formative to summative' process, conceptualising summative assessment as a summary judgement of attainment, which may be informed by snapshot and focused assessment activities. It was found that implementation of a 'formative to summative' approach required a shared understanding of key assessment concepts like validity and reliability; a seesaw balance model is proposed to support the development of such a shared understanding.

The Choice of Techniques and the Optimality of Market Equilibrium with Rational Expectations

Subjects: Economics

description: This paper shows that, in the absence of a complete set of risk markets, prices provide incorrect signals for guiding production decisions. Even if all individuals have rational expectations concerning the distribution of prices which will prevail on the market next period, the market allocation is, in general, not a constrained Pareto optimum. Essentially the only conditions under which, for all technologies, the market equilibrium is a constrained Pareto optimum are those in which risk markets are redundant. We derive the necessary and sufficient conditions for redundancy of risk markets, which turn out to be extremely restrictive.

description: We studied the X-ray timing and spectral variability of the X-ray source Sw J1644+57, a candidate for a tidal disruption event. We have separated the long-term trend (an initial decline followed by a plateau) from the short-term dips in the Swift light-curve. Power spectra and Lomb-Scargle periodograms hint at possible periodic modulation. By using structure function analysis, we have shown that the dips were not random but occurred preferentially at time intervals ~ [2.3, 4.5, 9] x 10^5 s and their higher-order multiples. After the plateau epoch, dipping resumed at ~ [0.7, 1.4] x 10^6 s and their multiples. We have also found that the X-ray spectrum became much softer during each of the early dip, while the spectrum outside the dips became mildly harder in its long-term evolution. We propose that the jet in the system undergoes precession and nutation, which causes the collimated core of the jet briefly to go out of our line of sight. The combined effects of precession and nutation provide a natural explanation for the peculiar patterns of the dips. We interpret the slow hardening of the baseline flux as a transition from an extended, optically thin emission region to a compact, more opaque emission core at the base of the jet.

description: The strong-isospin violation in $ψ(3770)\rightarrow J/ψ+ π^0$ via intermediate $D$ meson loops is investigated in an effective Lagrangian approach. In this process, there is only one $D$-meson loop contributing to the absorptive part, and the uncertainties due to the introduction of form factors can be minimized. With the help of QCD spectral sum rules (QSSR), we extract the $J/ψDD^*$ form factor as an implement from the first principle of QCD. The $DD^*π^0$ form factor can be well determined from the experimental data for $D\rightarrowπlν$. The exploration of the dispersion relation suggests the dominance of the dispersive part via the intermediate $D$ meson loops even below the open charm threshold. This investigation could provide further insights into the puzzling question on the mechanisms for $ψ(3770)\to$ non-$D\bar{D}$ transitions.

Sense of community

description: Bibliography: p. 132-138
description: A "sense of community" is expected as geographical community-justice initiatives are developed with the intent to provide informal social control, crime prevention, victim assistance, offender rehabilitation, and criminal offence sanctioning. While the focus of my research is the community-justice volunteer, the goal of my research is to problematize the concepts of community and sense of community as these appear to underpin community-justice initiatives, and explore the concepts of justice and fairness and their link (or not) to sense of community as understood by the community-justice volunteer. My qualitative study first reviews existing literature (primarily via the governmentality framework) on: the social contract; citizenship; responsible citizenship; the change from welfare-state to neo-liberal/neo-communitarian thinking; the (re)construction of community and its potential as a new form of governance; and sense of community. I then turn to an analysis of first-hand data generated by: 1) a demographic survey and 2) in-depth, semi-structured interviews. The population of interest from which I drew my sample participates in rural community-justice partnerships, varying models of which can be found across Canada. While my sample is not statistically generalizable, I would argue that the results are not atypical. In general, respondents held common views regarding community and "sense of community": both terms were often used interchangeably. While supporting the four elements provided in McMillan and Chavis's (1986) model of Psychological Sense of Community, my research also indicates the presence of two other factors that appear significant when respondents described their understanding of "sense of community" and its influence in their participation in community-justice partnerships. An ideal community that provided the environment and potential for sense of community was found in reality to be lacking for a variety of reasons, five of which are examined as they pertain to the issue of change. Justice and fairness were important to respondents though they had difficulty describing what either would look like in the current criminal justice system. Respondents did not, however, include having a "sense of community" as one of the qualities, or traits, required to potentially find justice and/or fairness (in the community). This research breaks new ground and is meant to provide empirical evidence regarding, voluntarism; community-justice partnerships; and the notion of justice, both real and perceived within and outside of the criminal justice system.
Sensitivity of rotational transitions in CH and CD to a possible variation of fundamental constants

description: The sensitivity of rotational transitions in CH and CD to a possible variation of fundamental constants has been investigated. Largely enhanced sensitivity coefficients are found for specific transitions which are due to accidental degeneracies between the different fine-structure manifolds. These degeneracies occur when the spin-orbit coupling constant is close to four times the rotational constant. CH and particularly CD match this condition closely. Unfortunately, an analysis of the transition strengths shows that the same condition that leads to an enhanced sensitivity suppresses the transition strength, making these transitions too weak to be of relevance for testing the variation of fundamental constants over cosmological time scales. We propose a test in CH based on the comparison between the rotational transitions between the e and f components of the Omega'=1/2,J=1/2 and Omega'=3/2,J=3/2 levels at 532 and 536 GHz and other rotational or Lambda-doublet transitions in CH involving the same absorbing ground levels. Such a test, to be performed by radioastronomy of highly redshifted objects, is robust against systematic effects.

title: Using action research to inquire into Assessment for Learning: implications for continuing professional development in English schools
Creators: name: McKenna, C.A
Publisher: name: Bath Spa University
Year: 2018

description: This thesis demonstrates the application of an Action Research framework, drawing on a variety of methodologies in order to understand the nature of my methodological inventiveness. The study was originally based on the attempt to develop an understanding of the pedagogy and practice relating to the implementation of the National Strategies in Assessment for Learning. It was developed by examining the strategies in a real world context using an Action Research framework as a basis for the synthesised methodology. The work on this thesis incorporated the "improve" paradigm of research and was grounded in the notion of social justice. This concept has been central to developing my own and others' practice. The theme of the research on Assessment for Learning was inspired by the first instance by the work by Black and William on Formative Assessment. The original research on which this thesis is based has taken place in a time frame constrained by the implementation of the strategy to the removal of the support, an action taken by the coalition government. The thesis has examined the pedagogical theories behind the concept of Assessment for Learning and the National Strategies. It has also considered how these ideas have been implemented in schools and the impact this has had on a variety of stakeholders. The work by Black and William suggests a rolling programme of action research type activities in order to develop the ideas they are postulating. This thesis has taken this concept and applied the idea creating a synthesised methodology which has resulted in my developing my own concept of methodological inventiveness. This thesis presents a number of original contributions to knowledge, centred on the fact that each school is a unique culture and therefore the implementation of a generic Continued Professional Development (CPD) strategy will prove difficult, the language of individual sites being different. Another significant contribution to knowledge is based on the terminology of assessment and how it is interpreted by practitioners, the different paradigms are discussed and conclusions drawn. This is based on the premise that educational practice equates with embodied knowledge and this thesis examines this concept. It also aims to clarify the meaning of social justice in the context of this study and the reasons for how this concept emerged. The concept of methodological inventiveness is also examined and conclusions drawn from the experience of this research.

description: We consider an ultra-small system of polarized bosons on an optical lattice with a ring topology interacting via long range dipole-dipole interactions. Dipoles polarized perpendicular to the plane of the ring reveal sharp transitions between different density wave phases. As the strength of the dipolar interactions is varied the behavior of the transitions is first-order like. For dipoles polarized in the plane of the ring the transitions between possible phases show pronounced sensitivity to the lattice depth. The abundance of possible configurations may be useful for quantum information applications.

description: This paper reaffirms the earlier argument that when individuals differ in their expectations concerning the returns to investments, there will be an optimal debt-equity ratio, at a sufficiently high debt level. It assumes that in the judgment of lenders there is a finite probability of bankruptcy. The terms at which individuals as well as firms can borrow depends on their indebtedness and perceptions of potential lenders. Stapleton's analysis rests on the unacceptable assumption that individuals can borrow an arbitrary amount at the riskless rate, even though the firm in which they have all their wealth invested cannot. A new proof of the potentiality of productive inefficiency in the presence of bankruptcy is also presented.

Creators: name: Hanel, R.T
Publisher: name: Bath Spa University
Year: 2018

description: This thesis contains both a creative and a critical component. In the critical component, my research explores the ways in which contemporary American biographers use first-person narration in their work. My focus is on questions of technique, particularly the selection of personal details, the moments in which the "I" appears, the consistency of the "I", and the narrator's voice. I closely examine three works that use the first-person approach in different ways: Jon Krakauer's Into the Wild, Rebecca Skloot's The Immortal Life of Henrietta Lacks, and Susan Griffith's short biography/memoir "Our Secret", which appears in A Chorus of Stones. The creative component is titled The Unlikely Terrorist: Camilla Hall and the Symbionese Liberation Army, a book-length biography in which I include first-person narration. The book explores the life of Camilla Hall, a member of the Symbionese Liberation Army, which was a radical domestic terrorist group active in the United States from 1973-1975. An important outcome of this research has been an increase in my understanding of the methods biographers use when inserting themselves into the stories of others. My critical research has shaped my creative writing, and I hope, will contribute to current scholarship about the place of first-person narration in biography.

We show that if X is minimal then G, modulo a normal subgroup of null entropy, is embedded as a Zariski-dense subset in a semi-simple real linear algebraic group of real rank < 3. Next, we show that X is a complex torus if the image of G is an almost abelian group of positive rank and the kernel is infinite, unless X is equivariantly non-trivially fibred.

Investigating biomolecular structure using fiber-optic UV resonance Raman spectroscopy
Creators: name: Addison, Christopher James
Publisher: name: University of British Columbia
Year: 2011

description: The observation of biomolecular structure is critical for the fundamental understanding of biological function. In this work, Fiber-optic UV Resonance Raman Spectroscopy (FO-UVRRS) was employed to study a number of structure-function relationships. A suite of metal-containing dioxygenase enzymes were studied in order to determine the substrate protonation state in the enzyme-substrate complex. Two enzymes with a high degree of sequence identity were studied, where one naturally incorporates a Fe²⁺ metal and the other uses Mn²⁺. Both enzymes react with the same substrate to form an equivalent muconic semialdehyde product. The enzymes are capable of incorporating the non-native metal into the enzymes with no effect on the kinetic properties. The Raman results show that the nature of the metal has no effect on the substrate protonation state. The degradation of 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoic acid (HOPDA) by BphD in the biphenyl catabolic pathway was studied using FO-UVRRS. Previous reports suggest that enol-keto tautomerization was a critical step in the mechanism of the carbon-carbon bond hydrolase. Hydrolytically impaired variants of BphD were used to study the binding mode of HOPDA. The results show that HOPDA binds to these variants in a strained-enolate geometry and does not undergo an enol-keto tautomerization upon enzyme binding. A fundamental FO-UVRRS study of locked nucleic acid (LNA) olgiomers was performed. LNA bases contain a C4’ to O2’ methylene bridge within the furanose ring of the nucleotide. The research results show that incorporation of a LNA induces a conformational change in the glycosyl bond between the backbone and the base. The results also show that incorporation of an LNA base induces changes in the secondary structure of the nucleic acid. In another study, chemical contamination of synthetic DNA oligomers was observed using FO-UVRRS. The data showed that commercially-available oligomers purified using standard desalting conditions are contaminated with residual benzamide. The results show that a previously assigned –NH₂ scissors vibration in the Raman study of oligomers overlaps with a prominent benzamide vibrational band, calling into question these previous assignments. The results also demonstrate that the extent of benzamide contamination varies from sample-to-sample and between different commercial sources.

description: We provide a perspective on studies aimed at observing the transition between hadronic and quark-gluonic descriptions of reactions involving light nuclei. We begin by summarizing the results for relatively simple reactions such as the pion form factor and the neutral pion transition form factor as well as that for the nucleon and end with exclusive photoreactions in our simplest nuclei. A particular focus will be on reactions involving the deuteron. It is noted that a firm understanding of these issues is essential for unraveling important structure information from processes such as deeply virtual Compton scattering as well as deeply virtual meson production. The connection to exotic phenomena such as color transparency will be discussed. A number of outstanding challenges will require new experiments at modern facilities on the horizon as well as further theoretical developments.

description: We show that "spanning" does not imply stockholder unanimity if there is trading in the shares of firms. Each basis vector of the space spanned by all firms' output vectors can be treated like a composite commodity. If, in addition to spanning, firms act as price takers with respect to prices of composite commodities, then there is unanimity. We analyze the spanning assumption for the vector space of contingent claims generated by firms' choices of debt-equity ratios. We show that there is a strong relationship between the Modigliani-Miller theorem, spanning, and the existence of a complete set of markets.

description: In August of 1998, a Phase I archaeological investigation was conducted by Richard Grubb & Associates for Ogden Environmental and Energy Services on behalf of the Historic Preservation Office, Environmental Division, Directorate of Public Works, U.S. Army, Fort Dix, New Jersey at the site of a proposed Ordnance Operations Building, Ammunition Storage Point in Tactical Training Area 5D, Fort Dix Military Installation, New Hanover Township, Burlington County, New Jersey. The Phase I investigation recommended a Phase II evaluation-level investigation of the area surrounding a cellar hole, believed to be the remains of the nineteenth century Cross/Grant/Harker House, located in the area proposed for the Ordnance Operations Building. The Phase II fieldwork was conducted by Richard Grubb & Associates personnel between April 22 and April 30, 1999.
The purpose of the Phase II investigation is to determine the eligibility of the Cross/Grant/Harker House for Pinelands Designation and eligibility for listing under Criterion D of the National Register of Historic Places. This evaluation will be based on the synthesis of historic research, artifact analysis, and site integrity.
Fieldwork conducted during the course of the Phase II investigation consisted of the excavation of 35 shovel test pits, two 3 by 5 foot trenches, two features, and three 3 foot square test units. Fieldwork revealed that the site exhibited considerable disturbance relating to the military occupation of the area. Twentieth century military debris associated with training exercises was found at considerable depth, suggesting the excavation of foxholes and other subsurface activity. The structural features associated with the cellar hole were the only undisturbed features. Historic artifacts were quite sparse throughout the APE. The material record indicates that there are insufficient remains at this site for it to be considered eligible for Pinelands Designation, or for listing in the National Register of Historic Places.
This report includes a annotated copy of the Technical proposal and cost breakdown for the Phase II Archaeological Investigation of Ammunition Storage Point at Fort Dix Military Installation.

description: This research study has been guided by the following orienting question: How do highly proficient adult non-native English speakers perceive their second vocabulary learning process? In broad strokes, the objectives of this dissertation include assessing the vocabulary size and profile and the English proficiency of highly proficient adult nonnative English speakers, and gaining insights into the factors to which they attribute their success in vocabulary acquisition. The sample consisted of 20 adult highly-proficient non-native speakers, who arrived in Canada after the age of 18 and who are academically or professionally successful. The data are drawn from several sources: a vocabulary size test, language proficiency assessments, informal interviews, questionnaires, and participants' samples of professional writing. Data from interviews and questionnaires were cross-analyzed or triangulated, following the principles of the grounded theory method. All 20 participants obtained native-like scores on the vocabulary size test, ranging from 13,500 to 20,000 base words and the group average vocabulary profile met all 3 criteria for the native-like academic writing standard proposed by Morris and Cobb (2004). All participants demonstrated close-to-native English proficiency and were assessed to be a Canadian Language Benchmark (CLB) 10+ in reading and listening and most participants obtained at least a CLB 9 in writing and speaking. 111 The emergent theory of successful second language vocabulary acquisition suggests that the development of native-like L2 vocabulary and close-to native L2 proficiency in young adults is associated with a combination of situational factors linguistic factors (L2 input), individual differences (socio-psychological, affective and cognitive), and learner processes (strategies). Adult NNS who acquire native-like L2 vocabulary knowledge and close-to-native L2 proficiency (CLB 1 O+) are exceptional individuals who take advantage of their inner means and outer resources, available in the L2 society. The two underlying forces that drive their success and activate a unique combination of situational factors , L2 input, individual differences, and learning strategies are awareness of inner and outer resources and willpower to consistently employ these resources in order to make language and vocabulary gains. Based on the categories that emerged, the study outlines a profile of exceptional L2 vocabulary learners. lV
Density-dependent deformed relativistic Hartree-Bogoliubov theory in continuum

description: The deformed relativistic Hartree-Bogoliubov theory in continuum with the density-dependent meson-nucleon couplings is developed. The formulism is briefly presented with the emphasis on handling the density-dependent couplings, meson fields, and potentials in axially deformed system with partial wave method. Taking the neutron-rich nucleus $^{38}$Mg as an example, the newly developed code is verified by the spherical relativistic continuum Hartree-Bogoliubov calculations, where only the spherical components of the densities are considered. When the deformation is included self-consistently, it is shown that the spherical components of density-dependent coupling strengths are dominant, while the contributions from low-order deformed components are not negligible.

description: The U.S. economy clearly needs stimulation, but the Obama administration‘s plan for accelerated depreciation is an “˜old economy‘ approach to stimulating aggregate investment and unlikely to ease the Great Recession, according to Michael Cragg of Brattle Group and Joseph Stiglitz of Columbia University. The authors suggest alternative policies consisting of carefully designed carrots and sticks.
title: On edge: an exploration of cultural identity through ceramic practice

description: My project investigates the concept of ‘in-betweenness’ and uses a range of research methods including fieldwork and oral history interviews in Taiwan and practice-led work in ceramics. Living away from my homeland gives me a clearer perspective of the culture in which I grew up, as well as an outsider’s perspective of British culture. The cross-cultural experience provides a platform from which I can address the questions of who I am and how I might express and communicate my experience of in-betweenness as a place where I can survive - where I can draw breath to help me cope with the challenges of living in two cultures. My research aims are: to explore the impact that living in a state of ‘inbetweenness’ can have on perceptions of self; to develop a visual language to communicate this experience; and to explore my own expression of cultural identity in relation to theory in the field. My theoretical framework derives from Gayatari Spivak’s work on colonialism and post-colonialism. Taiwan is a much-colonized culture and so Spivak’s focus on everyday experience prompted me undertake a field trip to Taiwan in 2013 to gather supporting data. I interviewed 22 Taiwanese female ceramicists: 5 indigenous women living in rural eastern Taiwan and 17 women living in urban areas. The field trip revealed a significant difference between the urban and the rural women’s ceramics (context, process and product) which, along with a growing awareness of Taiwanese social rituals, influenced my clay work. I could then create a bridge to a better understanding of cultural identity in my own research and practice. My ceramic practice was developed in three main locations: Bath Spa School of Art and Design and during two artist-residencies in Denmark and Taiwan. I have exhibited my main ceramic works (Sculptural Spoons, 8 Hours, Fingerprints, Bananas, Traditional Chinese Characters ) in different cultural environments and have been able to evaluate my work in response to visitor feedback. This project develops the idea of practice as a form of research, combining field work, creative practice and documentation. It widens awareness and proposes new ways for other artists to explore the experience of being ‘in-between’. My principle research questions are: How is my Taiwanese cultural identity expressed through making? How might ceramic practice be used to develop a visual language to communicate a personal experience of ‘in-betweenness’?

description: We present a new approach for summarizing clusters of documents on the same event, some of which are machine translations of foreign-language documents and some of which are English. Our approach to multilingual multi-document summarization uses text similarity to choose sentences from English documents based on the content of the machine translated documents. A manual evaluation shows that 68\% of the sentence replacements improve the summary, and the overall summarization approach outperforms first-sentence extraction baselines in automatic ROUGE-based evaluations.
title: Stories in the skin: empathy, embodiment and the novel
Creators: name: Geen, E
Publisher: name: Bath Spa University

description: 'The Listening' (Geen, 2018) and the critical piece that accompanies it examine the entanglement of the body, empathy and narrative. 'The Listening' is set in a much changed future Bristol where the race of "God Children" rule over the "Ffieth" and magic, of a sort, is considered possible. The novel follows its agender protagonist Asha in its fight to take control over the narratives that are imposed on it, including the stories of its mother and societal discourses on gender and race. Through Asha's struggles, the novel offers an account of how narratives can impose upon the body as a form of violence but also how stories, and the sharing of them, can be an act of healing empathy. Its exploration of the uncanny territory between the body and language contributes to the field of speculative literature by offering a contemporary response to classic texts, such as Ursula Le Guin's 'A Wizard of Earthsea' (1968) and 'The Left Hand of Darkness' (1969). The accompanying ficto-critical work gives an account of the research that informed 'The Listening' and acts as an analysis of the novel's treatment of empathy and the body. The work contributes to the dialogue on the ability of literature to evoke empathy by arguing that the process is not just a cognitive one, as is widely assumed, but is also embodied. Suggestions are made as to how a novelist can apply these ideas to their craft. The thesis as a whole can be understood as an investigation of the power of words over the body and the power of the body over words, as both empathy and violence.
