description: We report a linear dependence of the phonon splitting Δωon the non-dominant exchange coupling constant J_{nd} in the antiferromagnetic transition-metal monoxides MnO, FeO, CoO, NiO, and in the frustrated antiferromagnetic oxide spinels CdCr2O4, MgCr2O4, and ZnCr2O4. It directly confirms the theoretical prediction of an exchange induced splitting of the zone-centre optical phonon for the monoxides and explains the magnitude and the change of sign of the phonon splitting on changing the sign of the non-dominant exchange also in the frustrated oxide spinels. The experimentally found linear relation \hbarΔω= βJ_{nd} S^2 with slope β= 3.7 describes the splitting for both systems and agrees with the observations in the antiferromagnets KCoF3 and KNiF3 with perovskite structure and negligible next-nearest neighbour coupling. The common behavior found for very different classes of cubic antiferromagnets suggests a universal dependence of the exchange-induced phonon splitting at the antiferromagnetic transition on the non-dominant exchange coupling.

title: Stiffness Control of Variable Serial Elastic Actuators: Energy Efficiency through Exploitation of Natural Dynamics

description: Variable elastic actuators are very promising for applications in physical human–robot interaction. Besides enabling human safety, such actuators can support energy efficiency, especially if the natural behavior of the system is exploited. In this paper, the power and energy consumption of variable stiffness actuators with serial elasticity is investigated analytically and experimentally. Besides the fundamental mechanics, the influence of friction and electrical losses is discussed. A simple but effective stiffness control method is used to exploit the corresponding knowledge of natural dynamics by tuning the system to antiresonance operation. Despite nonlinear friction effects and additional electrical dynamics, the consideration of the ideal mechanical dynamics is completely sufficient for stiffness control. Simulations and experiments show that this yields a distinct reduction in power and energy consumption, which underlines the suitability of the control strategy.

description: Background: Dystonia is a relatively common feature of spinocerebellar ataxia 3 (SCA3). Childhood onset of SCA3 is rare and typically associated with either relatively large, or homozygous, CAG repeat expansions. Case report: We describe a 10-year-old girl with SCA3, who presented with tongue dystonia in addition to limb dystonia and gait ataxia due to a heterozygous expansion of 84 repeats in ATXN3. Discussion: Diagnosis of the SCAs can be challenging, and even more so in children. Tongue dystonia has not previously been documented in SCA3.

description: We compute the Cech cohomology with integer coefficients of one-dimensional tiling spaces arising from not just one, but several different substitutions, all acting on the same set of tiles. These calculations involve the introduction of a universal version of the Anderson-Putnam complex. We show that, under a certain condition on the substitutions, the projective limit of this universal Anderson-Putnam complex is isomorphic to the tiling space, and we introduce a simplified universal Anderson-Putnam complex that can be used to compute Cech cohomology. We then use this simplified complex to place bounds on the rank of the first cohomology group of a one-dimensional substitution tiling space in terms of the number of tiles.

Postcolonial aspiration and contestation : politics and poetics of nationalist discourses in two national museums of South Korea
Creators: name: Chun, Kyung Hyo
Publisher: name: University of British Columbia
Year: 2012

description: After colonial liberation from Japan in 1945, Koreans have been eager to establish their sovereignty and to elevate national pride through nationalism. In South Korea, the nationalist discourse is ubiquitous, and generated top-down directly from the government as well as bottom-up in both traditional media and new social media. Emphasizing the unity, longevity, and distinctiveness of the Korean people by promoting nationalism based on the idea of ethnic homogeneity was a way of both redressing a traumatic colonial past and integrating modern social theories. While the nationalist discourse in South Korea constantly reinforces the uniqueness of Korean people and the worthiness of its splendid culture asserted to be of “five thousand years,” South Korean nationalism is far from being self-sufficient. One of the most significant motivational forces for nationalist consciousness in South Korea is not self-determination but its postcoloniality. South Korea’s anticolonial self definition is a direct reaction to Japanese colonialism (1910-1945), and the aggressive pervasiveness of nationalism in contemporary South Korean society is the prescribed way of rejecting and erasing a past both undesirable and regrettable. This prescribed ethnic nationalism is extremely problematic in both its ahistoricity and increasingly conspicuous irrelevancy in the face of an increasingly multiculturalizing contemporary South Korean population. By examining the interplay between postcoloniality and nationalism, this dissertation examines the two major national museums of South Korea, the National Museum of Korea and the National Folk Museum of Korea. Conceptualizing museums as complex sites where different social, political, and cultural agendas are projected and contested, this dissertation attempts to contextualize the discourses and phenomena of nationalism and postcoloniality in contemporary South Korea within the “contact zone” of museums. While the use of “contact zone” in understanding the nature of museums is strongly informed by James Clifford’s (1997) adoption of Mary Louise Pratt’s term (Pratt 1992), this dissertation aims to broaden the scope of the concept by not limiting the discussion to the dialogue between the exhibited and the exhibitor, but by extending it to mean the process by which museums, the audience, and the society interact to generate and reinforce anticolonial nationalism in South Korea.

description: Xanthosoma mexicanum Liebm. Material examined. Cerro Pirre; 07°52′N, 077°44′W; 11 Apr. 1967; N. Bristán 596 (MO). Identification. This species is characterized by having terrestrial habit, subterranean cormose stems, densely pubescent subterete petioles, deltate or ovate to oblongovate simple blades, cordate to subsagittate at base, pubescent on both surfaces; spathe tube uniformly green externally, purple internally and spathe blade whitish or cream; spadices with whitish male portion, purple sterile portion, and pale-yellow female portion. On Cerro Pirre, Xanthosoma mexicanum is the only species of the genus that has pubescent leaves. Distribution and ecology. Brazil, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, and Venezuela. In the only examined specimen it was not specified in which locality of Cerro Pirre was found. Due to this, it is not possible to know the habitat where this species ocurrs in the study site. According to Croat et al. (2017b), the individuals of X. mexicanum disappear during the dry season and reappear in the rainy season.

The smooth Yamabe invariants σ(M) and σ(N) satisfy σ(N)\ge min (σ(M),Λ) for Λ>0. We derive explicit lower bounds for Λin dimensions where previous methods failed, namely for (n,k)\in {(4,1),(5,1),(5,2),(6,3),(9,1),(10,1)}. With methods from surgery theory and bordism theory several gap phenomena for smooth Yamabe invariants can be deduced.

description: Subacute sclerosing panencephalitis (SSPE) is a devastating brain disorder that typically affects children and adolescents. SSPE is caused by persistent measles virus infection. The mechanisms that facilitate the measles virus entering the brain, and persisting and proliferating there for very long periods are not precisely known. Once inside the brain, the measles viral genome undergoes a series of mutations, particularly in the M and F protein genes. These mutations are considered responsible for viral persistence and transneuronal spread inside the brain. Measles viral genome isolated from human brain tissues demonstrates clustered mutations in the virus genome, particularly in the M gene. These mutations destroy the structure and functioning of the encoded proteins. Complete infectious virus particle has rarely been demonstrated in the brain tissue.1 In the brain, the mutated measles virus triggers an intense inflammatory reaction that leads neuron destruction.

description: Knowledge of all-$α'$ higher derivative corrections to leading order BPS and non-BPS brane actions would serve in future endeavor of determining the complete form of the non-abelian BPS and tachyonic effective actions. In this paper, we note that there is a universality in the all-$α'$ order corrections to BPS and non-BPS branes. We compute amplitudes between one Ramond-Ramond $C$-field vertex operator and several SYM gauge/scalar vertex operators. Specifically, we evaluate in closed form string correlators of two-point amplitudes $\cal A^{Cϕ}$, $\cal A^{CA}$, a three-point amplitude $\cal A^{Cϕϕ}$ and a four-point amplitude $\cal A^{Cϕϕϕ}$. We carry out pole and contact term analysis. In particular we reproduce some of the contact terms and the infinite massless poles of $\cal A^{Cϕϕϕ}$ by SYM vertices obtained through the universality.

description: No abstracts are to be cited without prior reference to the author.An ecosystem approach to understanding large-scale patterns in exploited systems caused by both climate change and human activity increasingly relies on the use of numerical models. In the past, physical, lower and higher trophic level models were developed, tested, and implemented independently of each other. Recently, the advances in physics and biology have created the needed pieces for a comprehensive (end-to-end) ecosystem model, including humans as a dynamical component. The challenge is to integrate all the components, and examples of fully-coupled end-to-end models are relatively rare. This is partly due to the perception that blending separate yet complex sub-models is impractical because of demanding computational requirements and partly due to the respective communities working independently. We present our progress to date on the development of an end-to-end model modeling framework within the widely-used ROMS (Regional Ocean Modeling System) circulation model. The NEMURO Nutrient-PhytoplanktonZooplankton (NPZ) submodel provides the lower trophic level dynamics, and a multispecies individual-based submodel simulates fish population and community dynamics, including fishing fleets as one of the predator species. All of these models exist in various forms, but the individual sub-models have never been harmonized together into one integrated analysis tool useful for synthesis, integration, and prediction. This model framework was designed to investigate the effects of climate and fishing on marine ecosystems within one model that includes dynamical feedbacks among the different systems. We describe the conceptual and technical challenges involved in assembling and implementing such a model and we will present some early results of a test-bed (proof of principle) application developed to study the low-frequency fluctuations of sardine and anchovy

description: Based on the NMR measurements on Bi$_2$Sr$_{2-x}$La$_x$CuO$_{6+δ}$ (La-Bi2201) in strong magnetic fields, we identify the non-superconducting pseudogap phase in the cuprates as a Luttinger-volume violating Fermi liquid (LvvFL). This state is a zero temperature quantum liquid that does not break translational symmetry, and yet, the Fermi surface encloses a volume smaller than the large one given by the Luttinger theorem. The particle number enclosed by the small Fermi surface in the LvvFL equals the doping level $p$, not the total electron number $n_e=1-p$. Both the phase string theory and the dopon theory are introduced to describe the LvvFL. For the dopon theory, we can obtain a semi-quantitative agreement with the NMR experiments.

description: Background: Essential tremor (ET) is a common movement disorder characterized by kinetic and postural tremor in the upper extremities and frequently in the midline. Persons with ET often also exhibit gait ataxia. Previous studies have observed associations between midline tremor severity and gait ataxia in persons with ET, suggesting a common pathophysiology distinct from that of upper extremity tremor. However, a causal link between midline tremor and gait impairment has not been established. Methods: We investigated tremor and gait in 24 persons with ET before and after implantation of unilateral deep brain stimulation into the ventralis intermedius nucleus of the thalamus. Results: Stimulation significantly improved tremor in the targeted upper extremity and midline. However, gait was unaffected at the cohort level. Furthermore, improvement in midline tremor was not significantly associated with gait improvement. Discussion: These findings revealed that midline tremor and gait impairment may be dissociable in persons with ET.

description: Hand-raising is an extremely useful device for classroom self-selection. According to Sahlström (2002), it exhibits a student’s willingness to participate, and is a means by which to attract the attention of the teacher. Kawabe, Yamamoto, Aoyagi, and Watanabe (2014) analyzed various situations and student factors to affect hand-raising in the classroom. The practice of hand-raising is generally found to occur at the teacher’s turn transition relevant places, or TRPs (Sacks, Schegloff, & Jefferson, 1974). The conventional process of self-selection with hand-raising involves a student bidding for a nomination, and the self-selector becoming ratified to speak after the teacher nomination is provided. It was also suggested that later bidders tend to be selected more frequently than the first bidders, who may raise their hands slightly prior to the teacher’s early TRPs. Thus, “teachers may reward the late hand-raisers for sufficient listening” (Sahlström, 2002, p. 53-54).

description: We study the properties of the conformal blocks of the conformal field theories with Virasoro or W-extended symmetry. When the conformal blocks contain only second-order degenerate fields, the conformal blocks obey second order differential equations and they can be interpreted as ground-state wave functions of a trigonometric Calogero-Sutherland Hamiltonian with non-trivial braiding properties. A generalized duality property relates the two types of second order degenerate fields. By studying this duality we found that the excited states of the Calogero-Sutherland Hamiltonian are characterized by two partitions, or in the case of WA_{k-1} theories by k partitions. By extending the conformal field theories under consideration by a u(1) field, we find that we can put in correspondence the states in the Hilbert state of the extended CFT with the excited non-polynomial eigenstates of the Calogero-Sutherland Hamiltonian. When the action of the Calogero-Sutherland integrals of motion is translated on the Hilbert space, they become identical to the integrals of motion recently discovered by Alba, Fateev, Litvinov and Tarnopolsky in Liouville theory in the context of the AGT conjecture. Upon bosonisation, these integrals of motion can be expressed as a sum of two, or in general k, bosonic Calogero-Sutherland Hamiltonian coupled by an interaction term with a triangular structure. For special values of the coupling constant, the conformal blocks can be expressed in terms of Jack polynomials with pairing properties, and they give electron wave functions for special Fractional Quantum Hall states

Art as ecological practice : a curriculum of movement for teacher education methods
Creators: name: Triggs, Valerie
Publisher: name: University of British Columbia
Year: 2012

description: This a/r/tographic research investigates the partially accessible forces of movement that engender and co-substantiate experience. It renders an image of a vital socio-geologic ecology consisting of feelings of the energies of movement of all bodies made through struggles of rendering manifest the fullness of experience in its every example. In regards to teacher education methods, this is addressed as both an ecological and aesthetic issue. Feelings of capacity for being affected and for affecting generate more reality. Rather than attempting to separate, unqualified feelings emerging within affects’ temporal events add qualities with an existence and energy of their own. Increasing standardization, accountability schemes and attempted control of quality pose problems for the ecological significance of feelings of capacity to vary. This research addresses methods rather than just the subjects engaged in them to generate an image of a more tightly imbricated ecology that also includes the affects of our practices. It seeks educational experiences where subjects of all kinds subsist to the extent that they resonate with feelings of capacity for being moved and for moving within this ecology. Each chapter re-poses the issue of conveying experience’s simultaneity of continuity and discontinuity. Aesthetic practice and art-making are needed for feelings that precede cognition and for more repeated availability of making determinations within experience which are not simply opportunities for direct exchange but rather tokens of trust for invention and unprecedented space. Drawing concepts from a variety of disciplines, each chapter re-poses educational experience in ways that do not put methods in charge and through aesthetic experience, reconnect to the world by opening to the non-human world of which we are a part. Tending towards teacher education as currere, a living curriculum, this study suggests three qualities of assessment: availability, arrival, and the analog. Through initiating and proliferating creative practices, a/r/tographic methodology in teacher education is encouraged to draw on art’s methods of generating productive entanglements. Repeated affective engagement in creative practice is suggested towards augmenting and sustaining a more inhabitable present and future.

description: No abstracts are to be cited without prior reference to the author.Mechanistic tools such as bioenergetics models allow to predict the changes in fish distribution and productivity under global change scenarios. Here we used a Dynamic Energy Budget (DEB) model that was developed for adult anchovy to estimate the suitability of environmental conditions for that species. The DEB model calculates the energy for somatic maintenance, growth and reproduction, given temperature and food forcings. In the DEB theory, allocation for somatic maintenance has priority on others functions. Therefore the DEB model can identify physiologically limiting conditions: when assimilated food is insufficient at a given temperature the energy stored for reproduction will be re-allocated to pay for somatic maintenance costs. We used this approach to define an index of habitat suitability, which was the rate of re-allocation of reserves to pay for maintenance costs. The DEB was run with constant temperature and food conditions, and the rate of re-allocation of reserves assessed. This run was repeated for a wide range of temperature and food conditions, which led to the construction of charts that related environmental conditions to the suitability index. Biophysical NPZD (nutrient, phytoplankton, zooplankton detritus) models were used to hindcast climate-forced variability in prey fields and temperature over the Bay of Biscay and the North Sea. Unsuitability was mapped based on the suitability charts and the long-term hindcasted conditions. The spatio-temporal extent of unsuitable habitats revealed the longterm pattern of anchovy presence, critical seasons and core habitats in the Bay of Biscay and the North Sea. Unsuitable winter conditions decreased in area coverage as temperature increased.

description: We present measurements of the triaxial dark matter halo shapes and alignment correlation functions in the Millennium and Millennium-2 dark matter N-body simulations. These two simulations allow us to measure the distributions of halo shapes down to 10% of the virial radius over a halo mass range of 6E9 - 2E14 M_sun/h. We largely confirm previous results on the distributions of halo axis ratios as a function of halo mass, but we find that the median angle between halo major axes at different halo radii can vary by a factor of 2 between the Millennium-1 and 2 simulations because of the different mass resolution. Thus, error in the shape determinations from limited resolution is potentially degenerate with the misalignment of halo inner and outer shapes used to constrain Brightest Cluster Galaxy alignments in previous works. We also present simplifying parameterizations for the 3-D halo-mass alignment correlation functions that are necessary ingredients for triaxial halo models of large-scale structure and models of galaxy intrinsic alignments as contaminants for cosmic shear surveys. We measure strong alignments between halos of all masses and the surrounding dark matter overdensities out to several tens of Mpc/h, in agreement with observed shear-galaxy and cluster shape correlations. We use these measurements to forecast the contribution to the weak lensing signal around galaxy clusters from correlated mass along the line-of-sight. For prolate clusters with major axes aligned with the line-of-sight the fraction of the weak lensing signal from mass external to the cluster can be twice that predicted if the excess halo alignment correlation is assumed to be zero.

description: Born exactly a year apart, sisters Valentina and Zinaida Brumberg worked together their entire careers in the Soviet animation industry, becoming known as the “grandmothers of Russian animation” for their work in the fairytale genre (Katz 2016, 248n1). The Brumberg sisters are notable in Russian animation because they were among the first generation of animators in the country during the Revolutionary years, a unique environment that allowed women—even Jewish women—to make their way to the top of the industry. Perhaps their presence is more notable in the international arena as animation was dominated by men in the early decades and Valentina and Zinaida were among the first women in world animation, alongside anatomized pockets of female artists, such as Lotte Reiniger in Germany, Helena Smith Dayton in America, and Hermína Týrlová in Czechoslovakia. The Brumberg sisters were also at the forefront of many technical and aesthetic innovations, such as the projection of animated segments on theatrical stages, the use of paper cut-outs, the integration of folk styles for the stylization of indigenous tales, and the introduction of sound to Soviet animation.

description: We use a stochastic approach to assess the returns from blueberry production regarding observed blueberry price and yield variability. We extend the deterministic budget to stochastic by using triangular distribution and using Monte Carlo simulations. We use net present value (NPV) to assess and compare the returns. We observed disparity in the expected NPVs from two budget systems, and the chance of getting positive NPV studied under the stochastic budget was too low (23.85%–30.24%). This result shows the need for a stochastic approach to analyze growers’ profit, which helps making investment decisions. Moreover, this study is useful for farmers and farm risk analyzers.

description: We determine the mixing time of a simple Gibbs sampler on the unit simplex, confirming a conjecture of Aldous. The upper bound is based on a two-step coupling, where the first step is a simple contraction argument and the second step is a non-Markovian coupling. We also present a MCMC-based perfect sampling algorithm based on our proof which can be applied with Gibbs samplers that are harder to analyze.

description: We describe the phenomenology of the flavour changing neutral current sector of a supersymmetric model, invariant under the T' discrete flavour group. This model has been proposed in Ref.[1] and describes realistic leptonic and hadronic masses and mixings and predicts the amount of flavour changing in terms of the small flavour breaking parameter u in [0.007, 0.05]. For small values of u, the model almost reduces to the MSUGRA framework, while sizable deviations from MSUGRA can be, instead, observed when larger values of u and tan(beta) are considered. We analyse in detail the T' BR(mu --> e gamma) prediction, concerning the leptonic sector, while for the hadronic sector we concentrate on b --> s gamma and neutral B meson mass differences. Moreover, for the first time a comparative study on leptonic and hadronic observables for the T' model is performed. The experimental data on FCNC observables severely constrain the model in the small m_0 region. Conversely for larger m_0, the T' model satisfies all the bounds.

description: Effective cardiovascular disease (CVD) prevention relies on timely identification and intervention for individuals at risk. Conventional formula-based techniques have been demonstrated to over-or under-predict the risk of CVD in the Australian population. This study assessed the ability of machine learning models to predict CVD mortality risk in the Australian population and compare performance with the well-established Framingham model. Data is drawn from three Australian cohort studies: the North West Adelaide Health Study (NWAHS), the Australian Diabetes, Obesity, and Lifestyle study, and the Melbourne Collaborative Cohort Study (MCCS). Four machine learning models for predicting 15-year CVD mortality risk were developed and compared to the 2008 Framingham model. Machine learning models performed significantly better compared to the Framingham model when applied to the three Australian cohorts. Machine learning based models improved prediction by 2.7% to 5.2% across three Australian cohorts. In an aggregated cohort, machine learning models improved prediction by up to 5.1% (area-under-curve (AUC) 0.852, 95% CI 0.837–0.867). Net reclassification improvement (NRI) was up to 26% with machine learning models. Machine learning based models also showed improved performance when stratified by sex and diabetes status. Results suggest a potential for improving CVD risk prediction in the Australian population using machine learning models.

Gesture

description: In recent decades, the study of language learners’ embodied behavior amongst themselves has gained much currency. Broadly speaking, a wealth of studies on learner gestures connect gestures with second language acquisition, and have shown that gestures play a role in facilitating communication, acquisition, and retention (Gullberg, 1998, 2011, 2014; McCafferty, 2004; McCafferty & Gullberg, 2008; Stam & McCafferty, 2008). Another line of research examines learner gestures through the lens of sociocultural theory, and has found that learners use gestures to rehearse new knowledge and to self-regulate (Lee, 2008; McCafferty, 1998; Negueruela & Lantolf, 2008; Platt & Brooks, 2008). These studies, however, adopted experimental designs as a research method, and therefore, how learners actually use gestures when interacting with one another in situ remains largely a “black box.”

To this end, a growing number of research on learner gesture now adopts a conversation analytic perspective, which focuses on uncovering members’ method by analyzing naturally occurring classroom data (Olsher, 2004; 2008; Mori & Hayashi, 2006). Continuing this line of research, this paper aims to provide a preliminary account of how learners employ gestures to do vocabulary explanation in the context of group work.

description: One goal of physics instruction is to have students learn to make physical meaning of specific mathematical ideas, concepts, and procedures in different physical settings. As part of research investigating student learning in statistical physics, we are developing curriculum materials that guide students through a derivation of the Boltzmann factor, using a Taylor series expansion of entropy. Using results from written surveys, classroom observations, and both individual think-aloud and teaching interviews, we present evidence that many students can recognize and interpret series expansions, but they often lack fluency with the Taylor series despite previous exposures in both calculus and physics courses. We present students' successes and failures both using and interpreting Taylor series expansions in a variety of contexts.

The Future of Japan’s Financial Market

description: The subject of this paper is the relationship between developments in ICT and financial services and legislation, with a focus on the financial market. The basic approach is as follows: the services for financial transactions are built on the latest ICT, while the legal implications are stipulated by existing financial legislation. Although the rapid development of ICT has put enormous pressure on the financial industry to innovate their services, a nation’s financial legislation might show remarkable delay because of the path-dependency of lawmaking and enforcement systems. The discrepancy between the progress of ICT and delayed legislation varies by country, which reflects the relative competitiveness of financial industries and markets. Following this approach, I first show that the economic value produced by financial transactions consists of saving transaction costs. Transaction costs are basically information processing costs, which are determined by the level of ICT. Second, I explain the grand design of financial legislation and the peculiarities of Japan’s system. Generally speaking, the financial legislation of a country is composed of two categories. The first category is broad such as bankruptcy laws, and the second is narrow such as security exchange laws. Third, I examine the changes in financial transactions caused by ICT advancement in various countries and compare them to development in Japan. Fourth, I focus on current changes in financial markets by introducing examples from around the world. Former financial exchanges have transformed themselves into providers of financial market infrastructures. Global regulations have also changed in accordance with this transformation. Fifth, I identify two main challenges for Japan’s financial legislation in adapting to digital innovation.The first is how to design overall financial legislation, and the second is how to enforce individual legislation. I hope this paper stimulates further research and widespread construction on this theme.
The gravity duals of SO/USp superconformal quivers

description: We study the gravity duals of SO/USp superconformal quiver gauge theories realized by M5-branes wrapping on a Riemann surface ("G-curve") together with a Z_2-quotient. When the G-curve has no punctures, the gravity solutions are classified by the genus g of the G-curve and the torsion part of the four-form flux G_4. We also find that there is an interesting relation between anomaly contributions from two mysterious theories: T_{SO(2N)} theory with SO(2N)^3 flavor symmetry and \tilde{T}_{SO(2N)} theory with SO(2N) x USp(2N-2)^2 flavor symmetry. The dual gravity solutions for various SO/USp-type tails are also studied.

description: During my first semester of teaching English as a Foreign Language (EFL) I had five hundred students. I taught ten sections of Advanced English at the University of Science and Technology in Beijing, China. Each section had fifty students, whom I met with for one and a half hours once a week. The main goal of the course was to help undergraduates with advanced English proficiency pass the College English Test, a university exit requirement for all undergraduates in China. A secondary goal of the course was to prepare students for graduate study in English- speaking academic environments, since a majority of them would eventually go on to graduate studies in the U.S., England, or Australia.
