title: A corpus-driven study of features of Chinese students' undergraduate writing in UK universities
Creators: name: Leedham, Maria Elizabeth
Publisher: name: The Open University
Year: 2011

description: Chinese people now comprise the ‘largest single overseas student group in the UK’ with more than 85,000 Chinese students registered at UK institutions in 2009 (British Council, 2010a). While there have been many studies carried out on short argumentative essays from this group (e.g. Chen, 2009), and on postgraduate theses (e.g. Hyland, 2008b), there has been comparatively little research conducted on the high-stakes genre of undergraduate assignments. This study examines assessed writing from Chinese and British undergraduates studying in UK universities between 2000 and 2008; these are investigated using corpus linguistic procedures, supported by qualitative reading. A particular focus is the use of lexical chunks, or recurring strings of words. Findings from the literature on Chinese students’ written English indicate high use of informal chunks, connecting chunks, and those containing first person pronouns (e.g. Milton, 1999). This study found that while the Chinese students make greater use of particular connectors and the first person plural, both student groups make (limited) use of informal language. These areas of difference are more apparent in year 1/2 assignments than those from year 3, suggesting that students gradually conform to the academy’s expectations. Unexpected findings which have not been previously identified in the literature include Chinese students’ significantly higher use of tables, figures (or ‘visuals’) and lists, compared to the British students’ writing. Detailed exploration of writing within Biology, Economics and Engineering suggests that using visuals and lists are different, yet equally acceptable, ways of writing assignments. Since the writing of both student groups has been judged by discipline specialists to be of a high standard, it is argued that the difference in use of visuals and lists illustrates the range of acceptability at undergraduate level. The thesis proposes that scholars therefore need to consider expanding the notion of what constitutes ‘good’ student writing.

description: For an arbitrary octonion algebra, we determine all subalgebras. It turns out that every subalgebra of dimension less than four is associative, while every subalgebra of dimension greater than four is not associative. In any split octonion algebra, there are both associative and non-associative subalgebras of dimension four. Except for one-dimensional subalgebras spanned by idempotents, any two isomorphic subalgebras are in the same orbit under automorphisms.
Basin Hopping with Occasional Jumping

description: Basin-Hopping (BH) or Monte-Carlo Minimization (MCM) is so far the most reliable algorithms in chemical physics to search for the lowest-energy structure of atomic clusters and macromolecular systems. BH transforms the complex energy landscape into a collection of basins, and explores them by hopping, which is achieved by random Monte Carlo moves and acceptance/rejection using the Metropolis criterion. In this report, we introduce the jumping process in addition to the hopping process in BH. Jumping are invoked when the hopping stagnates by reaching the local optima, and are achieved using the Monte Carlo move at the temperature $T=\infty$ without rejection. Our Basin-Hopping with Occasional Jumping (BHOJ) algorithm is applied to the Lennard-Jones clusters of several notoriously difficult sizes. It was found that the probability of locating the true global optima using BHOJ is significantly higher than the original BH.

description: Detailed 4.8- and 8.6-GHz radio images of the entire Large Magellanic Cloud with half-power beamwidths of 33" at 4.8 GHz and 20" at 8.6 GHz have been obtained using the Australia Telescope Compact Array. A total of 7085 mosaic positions were used to cover an area of 6 degrees on a side. Full polarimetric observations were made. These images have sufficient spatial resolution (~8 and 5 pc, respectively) and sensitivity (3-sigma of 1 mJy/beam) to identify most of the individual SNRs and H II regions and also, in combination with available data from the Parkes 64-m telescope, the structure of the smooth emission in that galaxy. In addition, limited data using the sixth antenna at 4.5 to 6-km baselines are available to distinguish bright point sources (<3 and 2 arcsec, respectively) and to help estimate sizes of individual sources smaller than the resolution of the full survey. The resultant database will be valuable for statistical studies and comparisons with x-ray, optical and infrared surveys of the LMC with similar resolution.

4D Einstein-Lovelock black holes: Hierarchy of orders in curvature

description: The Einstein-Lovelock theory contains an infinite series of corrections to the Einstein term with an increasing power of the curvature. It is well-known that for large black holes the lowest (Gauss-Bonnet) term is the dominant one, while for smaller black holes higher curvature corrections become important. We will show that if one is limited by positive values of the coupling constants, then the dynamical instability of black holes serves as an effective cut-off of influence of higher curvature corrections in the 4D Einstein-Lovelock approach: the higher is the order of the Lovelock term, the smaller is the maximal value of the coupling constant allowing for stability, so that effectively only a first few orders can deform the observable values seemingly. For negative values of coupling constants this is not so, and, despite some suppression of higher order terms also occurs due to the decreasing threshold values of the coupling constant, this does not lead to an noticeable opportunity to neglect higher order corrections. In the case a lot of orders of Lovelock theory are taken into account, so that the black-hole solution depends on a great number of coupling constants, we propose a compact description of it in terms of only two or three parameters encoding all the observable values.

Lower limits on the Hubble Constant from models of Type Ia Supernovae
Creators: name: Stritzinger, M.
name: Leibundgut, B.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: By coupling observations of type Ia supernovae with results obtained from the best available numerical models we constrain the Hubble constant, independently of any external calibrators. We find an absolute lower limit of Ho > 50 km/s/Mpc. In addition, we construct a Hubble diagram with UVOIR light curves of 12 type Ia supernovae located in the Hubble flow, and when adopting the most likely values (obtained from 1-D and 3-D deflagration simulations) of the amount of (56)Ni produced in a typical event, we find values of Ho $\geq$ 66$\pm$8 and $\geq$ 78$\pm$9 km/s/Mpc, respectively. Our result may be difficult to reconcile with recent discussions in the literature as it seems that an Einstein-de Sitter universe requires Ho $\simeq$ 46 km/s/Mpc in order to fit the temperature power spectrum of the cosmic microwave background and maintain the age constraints of the oldest stars.

Can We Use Probing to Better Understand Fine-tuning and Knowledge Distillation of the BERT NLU?

description: In this article, we use probing to investigate phenomena that occur during fine-tuning and knowledge distillation of a BERT-based natural language understanding (NLU) model. Our ultimate purpose was to use probing to better understand practical production problems and consequently to build better NLU models. We designed experiments to see how fine-tuning changes the linguistic capabilities of BERT, what the optimal size of the fine-tuning dataset is, and what amount of information is contained in a distilled NLU based on a tiny Transformer. The results of the experiments show that the probing paradigm in its current form is not well suited to answer such questions. Structural, Edge and Conditional probes do not take into account how easy it is to decode probed information. Consequently, we conclude that quantification of information decodability is critical for many practical applications of the probing paradigm.

On Grothendieck type duality for the space of holomorphic functions of several variables

description: We describe the strong dual space $({\mathcal O} (D))^*$ for the space ${\mathcal O} (D)$ of holomorphic functions of several complex variables over a bounded Lipschitz domain $D$ with connected boundary $\partial D$ (as usual, ${\mathcal O} (D)$ is endowed with the topology of the uniform convergence on the compact subsets of $D$). We identify the dual space with a closed subspace of the space of harmonic functions on the closed set ${\mathbb C}^n\setminus D$, $n>1$, with elements vanishing at the infinity and satisfying the tangential Cauchy-Riemann equations on $\partial D$. In particular, we extend in a way the classical Grothendieck-K{ö}the-Sebastião e Silva duality for the space of holomorphic functions of one complex variable to the multi-dimensional situation. We use the Bochner-Martinelli kernel ${\mathfrak U}_n$ in ${\mathbb C}^n$, $n>1$, instead of the Cauchy kernel over the complex plane ${\mathbb C}$ and we prove that the duality holds true if and only if the space ${\mathcal O} (D)\cap H^1 (D)$ of the Sobolev holomorphic functions over $D$ is dense in ${\mathcal O} (D)$.
A route to improving RPA excitation energies through its connection to equation-of-motion coupled cluster theory

description: We revisit the connection between equation-of-motion coupled cluster (EOM-CC) and random phase approximation (RPA) explored recently by Berkelbach [J. Chem. Phys. 149, 041103 (2018)] and unify various methodological aspects of these diverse treatment of ground and excited states. The identity of RPA and EOM-CC based on the ring coupled cluster doubles is established with numerical results which was proved previously on theoretical grounds. We then introduce new approximations in EOM-CC and RPA family of methods, assess their numerical performance and explore a way to reap the benefits of such a connection to improve on excitation energies. Our results suggest that addition of perturbative corrections to account for double excitations and missing exchange effects could result in significantly improved estimates.
An integrable (classical and quantum) four-wave mixing Hamiltonian system

description: A four-wave mixing Hamiltonian system on the classical as well as on the quantum level is investigated. In the classical case, if one assumes the frequency resonance condition of the form $ω_0 -ω_1 +ω_2 -ω_3=0$, this Hamiltonian system is integrated in quadratures and the explicit formulas of solutions are presented. Under the same condition the spectral decomposition of quantum Hamiltonian is found and thus, the Heisenberg equation for this system is solved. Some applications of the obtained results in non-linear optics are disscused.
title: Competing constructions of children's participation in social care : analysing text and talk
Creators: name: Pinkney, Sharon
Publisher: name: The Open University
Year: 2005

description: This thesis is about how the concept of participation constructs children as subjects within social welfare formations. It is the result of a qualitative and interpretive research project using narrative and discourse analysis as key methodologies. The research is theoretically framed within the social constructionist, post-structuralist, feminist and psychoanalytic perspectives. By using these the thesis explores the competing constructions of children’s participation within social/legal policy texts and the discourses of social care. The focus is on children within contemporary UK welfare contexts who are either identified as being ‘at risk’ of significant harm or who are Looked After by the local authority. I examine the way that children’s participation is framed by the Children Act, 1989 (England and Wales), the United Nations Convention on the Rights of the Child and Quality Protects. I analyse the policy and interview texts to show how the discourses of protectionism, developmentalism, rights and managerialism compete unevenly across them. I argue that there is a new configuration of welfare developing around children’s services where managerialism is dominant and children’s rights are collapsed into the customer discourse. Children’s voices are either absent or mediated by adult/professionals in most of the formal policy texts. This thesis explores the affective and emotional aspects of performing participation with children. My data shows how individual professionals as well as the institutions of welfare experience anxiety and strain about how to enable and manage the participation of children. I show how professionals and welfare institutions develop various coping strategies, whose effects include the avoidance of the difficulties of listening to children.

description: The presence of market power in fuel retailing has been a major concern in Brazil, motivating antitrust investigations as well as economic research. However, lack of appropriate data precludes the estimation of straight market power indicators, leaving the possibility of using price series to identify market power. The objective of this study is to identify the presence of market power at the retail of fuel ethanol in cities of different sizes. The method adopted consists in verifying if price increases and decreases are transmitted asymmetrically to consumers, assuming that more intense transmission of price increases is related to the presence of market power. Monthly wholesale and retail price series of ethanol for cities with different sizes located in São Paulo State, Brazil, were used. The results indicate the presence of market power, since retailers were able to transmit price increases more rapidly and more intensively than price decreases for most cities. Such results suggest that asymmetry in price transmission can be a useful analytical tool to investigate market power and that antitrust authorities must observe the retail concentration and the behavior in the fuel market in order to protect consumers.

description: Doris Lessing, a world-renowned litterateur in aIl expressive style, depicts the essentials difficulties of ladies besides the social structure of her time. Lessing looks for modern ways to describe the background of a stuck female writer who expend her prior years in Africa, grows up to be energetic and dissatisfied marxist, is a socially dedicated author, a creator, a helpmate, or a lover, and is occasionally a lady. Lessing intends female's emotional problems in the middle of marriage ceremony and love, motherliness and occupation, injustice of the insincerity, disaffection of a single career female, and the emptiness of wedding in the established sequence and the community with her sharp and delicate perspective. Lessing depicts her female characters in a variety of social situations and from diverse male-female perspectives. Through her feminist writings, she attempts to awaken the women's community to fight patriarchy. This research paper will look at the psychological difficulties and intolerable encounter of potent her like Anna Wulf in The Golden Notebook and Mary Turner in The Grass Is Singing in order to achieve this goal.

description: For different purposes, state-of-the-art antigen detection mechanisms like ELISA are not sufficient in accuracy. Therefore, new approaches have to be developed to get highly sensitive technologies. Graphene's outstanding electrical properties, like ultrahigh charge mobility and sensitivity to dopants, make it to a promising candidate for new electronic devices and their utilization for sensing technologies. Recent progress in nanotechnology has enabled new possibilities and, thus, has allowed the construction of graphene field effect transistors (gFET). In this work, gFET arrays with high yield and good device-to-device characteristic have been fabricated. Siliconoxide (SiO2) and aluminiumoxide (Al2O3) have been used as insulating oxide layers. To utilize the gFET device, a chemical linker was attached by PI-PI stacking interactions. The liker himself binds antibody fragments, so called single chain variable fragments (scFv). In this approach, detection of HER3, a well known breast cancer biomarker, was of interest. Therefore, matching HER3 immunoglobulin G-antigen complexes were used. Conclusions about the concentration of HER3 antigens down to as small as ng/ml were deducible by monitoring the Dirac voltages of the gFET devices.

description: Tabular data provide answers to a significant portion of search queries. However, reciting an entire result table is impractical in conversational search systems. We propose to generate natural language summaries as answers to describe the complex information contained in a table. Through crowdsourcing experiments, we build a new conversation-oriented, open-domain table summarization dataset. It includes annotated table summaries, which not only answer questions but also help people explore other information in the table. We utilize this dataset to develop automatic table summarization systems as SOTA baselines. Based on the experimental results, we identify challenges and point out future research directions that this resource will support.

description: Partial cubes are graphs that can be isometrically embedded into hypercubes. Convex cycles play an important role in the study of partial cubes. In this paper, we prove that a regular partial cube is a hypercube (resp., a Doubled Odd graph, an even cycle of length $2n$ where $n\geqslant 4$) if and only if all its convex cycles are 4-cycles (resp., 6-cycles, $2n$-cycles). In particular, the partial cubes whose all convex cycles are 4-cycles are equivalent to almost-median graphs. Therefore, we conclude that regular almost-median graphs are exactly hypercubes, which generalizes the result by Mulder [J. Graph Theory, 4 (1980) 107--110] -- regular median graphs are hypercubes.

description: This paper analyzes the economic impacts of Brazilian Forest Code, in its different versions, on Brazil and its states. Three different scenarios were analyzed using an interregional computable general equilibrium model, the TERM-BR, from which we obtain national and regional results. Satellite imagery data was combined with economic information from the Brazilian Agricultural Census for the analysis. Model results show that the less restrictive new version of the law resulted in smaller negative economic impacts on the Brazilian economy. With the new law, the Brazilian GDP was reduced by 0.19%, or by 0.17%, when the system for Legal Reserves compensation in other state is used. This is smaller than the projected impact of the previous law, which we estimated to be a 0.37% reduction in the GDP. However, the results are heterogeneous across regions since the incidence of the restrictions is different in the alternative scenarios.

description: The objective of the research was to analyze the distribution of the credit use between the rural establishments, considering, as criteria, the number of establishments and participating in production value. To analyze this distribution, the percentage of credit used by the 50% lower and by the 5 and 10% larger establishments, the average value financed and the concentration index were calculated. The results showed that the distribution of funding between the agricultural establishments are concentrated, but tends to reflect the differences of these establishments with respect their contribution to the production value. This result is related to the effects of Pronaf, a program that benefits the establishments of the lower strata of area. In the absence of this program, the distribution of the government programs of credit would be much more concentrated. However, changes in the operational rules of this program, which favor more capitalized farmers and regions where they predominate, are probably reducing this effect.

description: We introduce four supersymmetric (SUSY) axion models in which the strong CP problem and the $μ$ problem are solved with the help of the Peccei-Quinn mechanism and the Kim-Nilles mechanism, respectively. The axion physics enriches the SUSY model by introducing axion as a dark matter candidate and, therefore, the lightest supersymmetric particle (LSP) could just be a part of the total dark matter. For this reason, axion relieves the tensions between SUSY models and numerous experimental measurements, such as the dark matter direct detection experiments and the precise measurements of anomalous magnetic moment of the muon $a_μ$. In the present paper, we investigate the constraints imposed by the latest $a_μ$ measurements and LUX-ZEPLIN (LZ) experiment on the relic density of the Higgsino-like LSP. Additionally, we consider the constraints arising from the cosmology of saxions and axinos, and their impacts on the parameter space of our models are carefully examined. For the axion constituting the remaining portion of dark matter, we find that the conventional misalignment mechanism can successfully account for the correct dark matter relic density observed by the Planck satellite.

description: The coherent control of electron beams and ultrafast electron wave packets dynamics have attracted significant attention in electron microscopy as well as in atomic physics. In order to unify the conceptual pictures developed in both fields, we demonstrate the generation and manipulation of tailored electron orbital angular momentum (OAM) superposition states either by employing customized holographic diffraction masks in a transmission electron microscope or by atomic multiphoton ionization utilizing pulse-shaper generated carrier-envelope phase stable bichromatic ultrashort laser pulses. Both techniques follow similar physical mechanisms based on Fourier synthesis of quantum mechanical superposition states allowing the preparation of a broad set of electron states with uncommon symmetries. We describe both approaches in a unified picture based on an advanced spatial and spectral double slit and point out important analogies. In addition, we analyze the topological charge and discuss the control mechanisms of the free-electron OAM superposition states. Their generation and manipulation by phase tailoring in transmission electron microscopy and atomic multiphoton ionization is illustrated on a 7-fold rotationally symmetric electron density distribution.

description: We present the results of a systematic study of thin-films of amorphous indium-oxide near the superconductor-insulator transition. We show that the film's resistivity follows a simple, well-defined, power-law dependence on the perpendicular magnetic field. This dependence holds well into the insulating state. Our results indicate that vortices play a central role in the transport of our films in the superconducting as well as insulating phases.

Manipulating social capital in eighteenth-century Prussia : the use and conceptualization of honor in the memoirs of Johann Dietz and Hans Ludwig Nehrlich
Creators: name: King, Andrew M.
Publisher: name: University of British Columbia

description: This paper examines the ways in which honor was used by artisans in eighteenth-century Prussia. Using the cases of three early modern Germans from artisan backgrounds; the Halloran barber Johann Dietz, his wife Elisabeth, and the cooper Hans Ludwig Nehrlich from the village of Sülzenbrücken, the paper investigates how artisans conceived of and used the concept of honor. As members of the urban artisanal milieu, Dietz, Elisabeth and Nehrlich were part of a culture in which honor and reputation were of utmost importance, and all three made use of the language of honor to explain and justify their actions when they were drawn into conflicts with other artisans or their social superiors. In their efforts to defend themselves from charges of dishonorable conduct, the three artisans demonstrate the surprising malleability of honor as an ordering concept in the early modern city. The dictates of the honorable guild-based community regulated the behavior of artisans and could potentially punish transgressive individuals with complete social, economic and political exclusion. However, the extent to which issues of honor permeated almost every facet of early modern artisan life and transcended the theoretically closed boundaries of the urban community allowed individuals such as Dietz, Elisabeth and Nehrlich, all of whom were accused of dishonorable conduct, to draw on the overlapping meanings and jurisdictions regulating honor to defend their actions. The discourse of honor in the early modern German city simultaneously served as a form of group social capital, which allowed the artisan community both to negotiate with urban authorities and to regulate the conduct of their individual members, and as a form of individual social capital which allowed certain artisans to defend or actively improve their social status, at times in the face of direct opposition from artisan peers or urban authorities.

description: Dicho trabajo analiza que pese a que las medidas de aislamiento social por la pandemia por COVID-19, han generado una mejora en la calidad ambiental, dicho beneficio no sería sostenible en el tiempo, toda vez que es consecuencia de una situación extraordinaria. Por el contrario, identifica la posibilidad de que se produzca la flexibilización y aplazamiento de las normas y políticas ambientales, como medidas para impulsar la economía. Ante ello, se postula que tanto los problemas causados por el COVID-19, así como los ambientales, económicos y sociales, sean analizados bajo la tesis del macroscopio de Rosnay, identificando las vinculaciones entre dichos problemas y atacándolas en conjunto. De esta manera, se identifican algunas similitudes entre el COVID-19, el cambio climático, la contaminación ambiental, la salud de las personas, la pérdida de biodiversidad y la recesión económica; planteando la viabilidad de una solución verde ante ellos, tal como algunos países europeos lo vienen proponiendo.

description: We investigate f_0-sigma mixing in the framework of light cone QCD sum rules and by employing the experimental results about the decay widths and the masses of these scalar mesons we estimate the scalar mixing angle by using sigma meson data and f_0 meson data. The two values we thus obtain of the scalar mixing angle are not entirely consistent with each other, possibly indicating that the structure of these mesons cannot be simple quark-antiquark states.

description: Understanding the doped Mott insulator is a central challenge in condensed matter physics. In this work, we first explicitly identify a new sign structure in the $t$-$t'$-$J$ model on the square lattice that replaces the conventional Fermi statistics for weakly interacting electrons. Then we show that the singular, i.e., the phase-string part of the sign structure in the partition function can be precisely turned off in a modified model. The density matrix renormalization group method is then employed to study these two models comparatively on finite-size systems, which is designed to unveil the consequences of the phase-string component. We find that the hole pairing is present not only in the quasi-long-range superconducting phase but also in the stripe phase of the $t$-$t'$-$J$ model. However, once the phase-string is switched off, both the superconducting and stripe orders together with the underlying hole pairing disappear. The corresponding ground state reduces to a trivial Fermi-liquid-like state with small hole Fermi pockets that is decoupled from the antiferromagnetic spin background. It is in sharp contrast to the original $t$-$t'$-$J$ model where large Fermi surfaces can be restored in the stripe phase found at $t'/t<0$ or the superconducting phase at $t'/t>0$ in the six-leg ladder calculation. Our study clearly demonstrates that the strong correlation effect in doped Mott insulator should be mainly attributed to the long-range quantum entanglement between the spin and charge, which is, non-perturbatively, beyond a simple spin-charge separation under the no double occupancy constraint.

description: The similarity theory is derived for ultra-relativistic laser-plasma interactions. First, it is shown that the most fundamental S-similarity is valid for both under- and overdense plasmas. Then, the particular case of tenious plasma is considered in great detail. It is shown that the electron dynamics in this case has two characteristic scales. The fast scale corresponds to relaxation to some attractor solution. The slow dynamics describes an adiabatic evolution of this attractor. This leads to a remarkable wave breaking exclusion rule in the 3D geometry. A similarity theory for the slow dynamics allows obtaining simple ``engineering'' scalings for the maximum electron energies, the number of accelerated electrons, the electron beam density, and for the acceleration distance. These scalings are aimed at design of a high-energy laser-plasma accelerator generating electron beams with superior properties.

description: Reducing the coefficient of boundary friction on steel surfaces is one of key technologies to improve the efficiency of machines such as automotive engines. It has been shown that the boundary friction on nanostructured steel surfaces in the sliding test using hydrocarbon lubricant molecules is smaller than the friction of normal steel surfaces. The main difference between the nanostructured and a normal surfaces is the density of grain boundaries and other surface defects. The surface defect can attract lubricant molecules and enhance lubricating film formation on metal surfaces. This can be one of the mechanisms that induce the friction reduction on the nanosructured steel surface. In this work, using first principles calculations, the adsorbability of a lubricant molecule, a fatty acid, on a defected iron surfaces has been studied. Adsorbability of the Fe(110) surface with symmetrical tilt Σ3(111) grain boundary was compared to that of the clean Fe(110) surface. As a result, we found that the molecule is adsorbed on sites close to the grain boundary more strongly (0.77 eV in average) than on the Fe surface without grain boundary.
