description: 	Since the introduction of film to Japan in the 1890s, Japanese cinema has been continually influenced by transnational processes of film production, distribution, promotion, and reception. This has led inevitably to questions about the inherent nationality of Japan’s film culture, despite the fact that Japanese cinema has often been subjected to analyses of its fundamental ‘Japaneseness’. This study seeks to make an original contribution to the field of Japanese film studies by investigating the contradictory ways in which Japan has functioned as a global cinematic brand in the period 2000 to 2010, and how this is interrelated with modes of promotion and reception in the English-speaking markets of the UK and the USA. Through textual and empirical analyses of seven films from the selected period and the non-Japanese consumption of them, this thesis argues that contemporary film exports are culturally-decentred in regards to their industrial and, to some extent, aesthetic dimensions. This results from contradictory modes of ‘cultural erasure’ and ‘cultural performance’ in the production of certain films, whereby aesthetic traces of cultural specificity are concealed or emphasised in relation to external commercial interests. Despite strategies of cultural erasure, explicit cinematic representations of cultural specificity remain highly valued as export commodities. Moreover, in the case of contemporary Japanese film exports, there are significant issues of ‘cultural ownership’ to be accounted for given the extent to which non-national industrial consortia (film producers, financers, DVD distributors, film festivals) have invested in the promotion and in some cases the production of Japanese films. Thus, both in relation to the aesthetic erasure of Japaneseness and their non-Japanese commercial identities, recent film exports can be viewed as non-national cultural products that have a commercial and cinematic identity connected to external influences as much as internal ones.

description: Although corrective feedback (CF) has attracted much attention in the field of second language acquisition, there is scant research pertaining to CF in naturalistic written computer-mediated communication (CMC). This exploratory study addressed this gap by describing the types of CF that occurred and evaluating their relative effects on learner uptake in two conditions: (1) asynchronous CMC and (2) synchronous CMC between four Native Speaker-Non-Native Speaker dyads. As a measure of effectiveness, learner uptake is defined as immediate or delayed learner responses to CF. Participants completed the following synchronous tasks: an introductory task, and a video-prompted discussion task via an online chat program. For the asynchronous task, the participants co-developed a 3-day travel plan via email. The findings showed that CF in the form of clarification requests existed in the ACMC environment, whereas recasts were the only type of CF observed in the SCMC environment. Although no evidence of immediate effect was shown during task performance, an instance of delayed effect was shown across tasks in the SCMC environment.

description: This working paper describes demography as opportunity, which is a simple idea grounded in a commitment to affirm the worth of the students who attend community colleges by being responsive to their life circumstances. As the demography of the nation changes—the United States is predicted to be majority minority by 2045—human capital investment in students from racial and ethnic groups, many of whom are first-generation college goers and low-income, is critical to the nation’s vitality. Demography as opportunity marries the racial and ethnic shifts underway in the country and in higher education with equity perspectives on historically disenfranchised populations. It is a constellation of policy and practice that abides by implementation principles common to well-executed change efforts. It attends to both people and place and aspires to strengthen communities and the nation by investing in the increasingly diverse population of college goers. Community colleges are the ideal venue for demography as opportunity not only because of who they serve but also because of what they do.

description: Language for specific purposes (LSP) has a long history in the language testing literature. An outgrowth of the communicative language movement of the 1970s, LSP testing arose out of the practical need to assess individuals’ abilities to perform specific tasks in academic and professional settings. This historical review traces the evolution of LSP testing in the language testing literature, focusing specifically on theory and research in two key areas: (a) authenticity and (b) the interaction between language knowledge and background knowledge. The review then turns to how Douglas (2000), in the most comprehensive treatment of LSP testing to date, incorporates insights from these two lines of work into his conceptualization. Throughout the review, tensions and debates emerging from the literature are discussed. The final section addresses the uncertain future of LSP in the language testing landscape.
Why an Indirect Measure of L2 Learner’s Willingness to Communicate in L2 Writing Requires Cautious Inferencing

description: In Exploring the dynamics of willingness to communicate (WTC) in written communication, Choe’s (this issue) preliminary case study explores an area of WTC that has not been fully addressed by WTC scholars: an analysis of WTC in written communication. In 1998, MacIntyre, Dörnyei, Clément and Noels stated regarding WTC, “We propose to extend WTC to influence other modes of production [other than oral], such as writing and comprehension of both spoken and written language” (p. 546). However, since 1998, there has been little research conducted on WTC in L2 writing. Originally conceptualized as an L1 construct, WTC has been defined as the probability of initiating, continuing, and expending on oral communication with an interlocutor. The underlying psychological assumption was that the probability of WTC episodes reflected one’s internal motivation and willingness to communicate orally, which was viewed as a fixed, trait-like variable closely associated with one’s congenital nature such as sociable personality or degree of extroversion (MacIntyre et al., 1998). When the concept of WTC was applied to the L2 context, a negative correlation between L1 WTC and L2 WTC revealed a different nature of L2 WTC. L2 WTC was found to be fluid and dynamic, open and interactive with L2 learning context and a host of other factors both learner internal and external that self-organizes to emerge a changing WTC orientation that is situation-specific. In light of this, according to the Complex Dynamic Systems Theory (CDST) approach to second language acquisition (SLA), L2 WTC features layers of potential factors that comprise situation-specific influences at a given moment-in-time as well as stable, enduring influences that are more resistant to change. In short, in CDST, L2 WTC is seen as an emergent property of both the stable, intrinsic nature of the learner and the dynamic nature of the learner’s external conditions.

description: In the present work, Ca-containing silicon oxycarbides (SiCaOC) with varying Ca content have been synthesized via sol-gel processing and thermal treatment in inert gas atmosphere (pyrolysis). It has been shown that the as-prepared SiCaOC materials with low Ca loadings (Ca/Si molar ratios = 0.05 or 0.12) were X-ray amorphous; their glassy network contains Q³ sites, indicating the presence of Ca²⁺ at non-bridging-oxygen sites. SiCaOC with high Ca content (i.e., Ca/Si molar ratio = 0.50) exhibits the presence of crystalline calcium silicate (mainly pseudowollastonite). Furthermore, it has been shown that the incorporation of Ca into the SiOC glassy network has a significant effect on its porosity and specific surface area. Thus, the as-prepared Ca-free SiOC material is shown to be non-porous and having a specific surface area (SSA) of 22.5 m²/g; whereas SiCaOC with Ca/Si molar ratio of 0.05 exhibits mesoporosity and a SSA value of 123.4 m²/g. The further increase of Ca content leads to a decrease of the SSA and the generation of macroporosity in SiCaOC; thus, SiCaOC with Ca/Si molar ratio of 0.12 is macroporous and exhibits a SSA value of 39.5 m²/g. Bioactivity assessment in simulated body fluid (SBF) confirms the hydroxyapatite formation on all SiCaOC samples after seven days soaking, unlike the relatively inert ternary silicon oxycarbide reference. In particular, SiCaOC with a Ca/Si molar ratio of 0.05 shows an increased apatite forming ability compared to that of SiCaOC with Ca/Si molar ratio of 0.12; this difference is considered to be a direct consequence of the significantly higher SSA of the sample with the Ca/Si ratio of 0.05. The present work indicates two effects of Ca incorporation into the silicon oxycarbide glassy network on its bioactivity: Firstly, Ca²⁺ is shown to contribute to the slight depolymerization of the network, which clearly triggers the hydroxyapatite formation (compare the bioactive behavior of SiOC to that of SiCaOC with Ca/Si molar ratio 0.12 upon SBF exposure); secondly, the Ca²⁺ incorporation seems to strongly affect the porosity and SSA in the prepared SiCaOC materials. There is an optimum of Ca loading into the silicon oxycarbide glassy network (at a Ca/Si molar ration of 0.05), which provides mesoporosity and reaches maximum SSA, both highly beneficial for the bioactive behavior of the materials. An increase of the Ca loading leads, in addition to the crystallization of calcium silicates, to a coarsening of the pores (i.e., macroporosity) and a significant decrease of the SSA, both negatively affecting the bioactivity.

description: The probability density functions (PDFs) for energy dissipation rates, created from time-series data of grid turbulence in a wind tunnel, are analyzed in a high precision by the theoretical formulae for PDFs within multifractal PDF theory which is constructed under the assumption that there are two main elements constituting fully developed turbulence, i.e., coherent and incoherent elements. The tail part of PDF, representing intermittent coherent motion, is determined by Tsallis-type PDF for singularity exponents essentially with one parameter with the help of new scaling relation whose validity is checked for the case of the grid turbulence. For the central part PDF representing both contributions from the coherent motion and the fluctuating incoherent motion surrounding the former, we introduced a trial function specified by three adjustable parameters which amazingly represent scaling behaviors in much wider area not restricted to the inertial range. From the investigation of the difference between two difference formulae approximating velocity time-derivative, it is revealed that the connection point between the central and tail parts of PDF extracted by theoretical analyses of PDFs is actually the boundary of the two kinds of instabilities associated respectively with coherent and incoherent elements.

description: No abstracts are to be cited without prior reference to the author.The northeast U.S. continental shelf Large Marine Ecosystem is a highly productive ecosystem that has experienced a general warming of water temperature since the 1960’s. This dynamic ecosystem spans from Cape Hatteras, North Carolina in the south to the Gulf of Maine. Within the ecosystem are four distinct sub-regions (from south to north: Middle-Atlantic Bight, Southern New England Shelf, Georges Bank and Gulf of Maine) that have different spatial and temporal patterns of phytoplankton biomass and production. Comparisons of annual surface chlorophyll concentrations in the northeast shelf ecosystem from MARMAP shipboard surveys (1977-1988) and ocean color remote sensing data (1997-2008) indicate that surface phytoplankton biomass is greater during the present decade (geometric mean = 1.48 mg m-3) than during the MARMAP period (geometric mean = 1.11 mg m-3).

description: The structure of the singularity that is formed in a relativistically large amplitude plasma wave close to the wavebreaking limit is found by using a simple waterbag electron distribution function. The electron density distribution in the breaking wave has a typical "peakon" form. The maximum value of the electric field in a thermal breaking plasma is obtained and compared to the cold plasma limit. The results of computer simulations for different initial electron distribution functions are in agreement with the theoretical conclusions.

description: No abstracts are to be cited without prior reference to the author.Chlorophyll and hydrographic conditions were m onitored in the southern Norwegian Sea in spring in the period 1991-2008. The area includes two differe nt water m asses: warm and saline Atlantic water in the south, separated from colder and le ss saline Arctic water in the north by the IcelandFaroe Front (IFF). Our results show that the inter-annual variations in the chl a concentration (Fav) were sim ilar in both water m asses (regression analysis p < 0.01) but with consistently higher concentrations in the Arctic water m ass north of the IFF. Furtherm ore the inter-annual variations in density change through the upper 50 m (Ddif) were very similar and highly correlated (p << 0.01) in both water m asses, and a regression analyses confir med a statistically significant relationship (p < 0.01) between the Fav and Ddif for the Arctic water mass, but not for the Atlantic. Thus stratification is the main controlling factor for the phytoplankton biomass in May, especially in the Arctic water mass north of the IFF. Our results also indi cate that stratification is m ainly governed by temperature; this is conf irmed by a tight relati onship between the tem perature gradient in the pycnocline and the chl a concentration above the pycnocline (F apd), especially in the Arctic water mass to the north of IFF.

description: We present the first science results from our Hubble Space Telescope Survey for Lyman limit absorption systems (LLS) using the low dispersion spectroscopic modes of the Advanced Camera for Surveys and the Wide Field Camera 3. Through an analysis of 71 quasars, we determine the incidence frequency of LLS per unit redshift and per unit path length, l(z) and l(x) respectively, over the redshift range 1 < z< 2.6, and find a weighted mean of l(x)=0.29 +/-0.05 for 2.0 < z < 2.5 through a joint analysis of our sample and that of Ribaudo et al. (2011). Through stacked spectrum analysis, we determine a median (mean) value of the mean free path to ionizing radiation at z=2.4 of lambda_mfp = 243(252)h^(-1) Mpc, with an error on the mean value of +/- 43h^(-1) Mpc. We also re-evaluate the estimates of lambda_mfp from Prochaska et al. (2009) and place constraints on the evolution of lambda_mfp with redshift, including an estimate of the "breakthrough" redshift of z = 1.6. Consistent with results at higher z, we find that a significant fraction of the opacity for absorption of ionizing photons comes from systems with N_HI <= 10^{17.5} cm^(-2) with a value for the total Lyman opacity of tau_lyman = 0.40 +/- 0.15. Finally, we determine that at minimum, a 5-parameter (4 power-law) model is needed to describe the column density distribution function f(N_HI, X) at z \sim 2.4, find that f(N_HI,X) undergoes no significant change in shape between z \sim 2.4 and z \sim 3.7, and provide our best fit model for f(N_HI,X).

Creative cities, creative spaces, and urban policy : the impacts of regulations on artist-run centres and independent arts spaces in Vancouver, British Columbia
Creators: name: Arthurs, Kerri Elizabeth
Publisher: name: University of British Columbia
Year: 2012

description: Over the last decade, emergence and popularity of the creative city has generated considerable interest in the significance of arts and culture to economic and community development. In this context, artists and cultural facilities are considered essential assets contributing to creativity and innovation by attracting skilled workers and business investments, revitalizing inner city industrial areas, and discursively reimagining and rebranding the city through cultural events and large-scale cultural infrastructure projects. This research examines the effects of regulations on the creation and operation of artist-run centres and independent arts facilities as essential sources of cultural production and creativity in Vancouver, British Columbia. Drawing on a series of in-depth, semi-structured, face-to-face interviews with the founding members, administrators, directors/curators, and/or primary operators of twelve artist-run facilities in Vancouver, research examines how artists and arts administrators experience the process of achieving bylaw and regulatory compliance to manage and sustain the operations of non-profit and independent arts spaces in a post-industrial context of policy implementation and urban redevelopment. Research addresses the strategies artists’ employ to achieve bylaw and regulatory compliance, as well as the contributions these spaces make to the cultural fabric of the creative city. Finally, research examines artists’ primary motivations for continuing their creative practices in increasingly challenging arts market and policy context. Research findings reveal that while non-profit and independent arts spaces contribute to both community revitalization and artistic development, issues pertaining to the urban planning and policy limit their community and economic development potential. As a result, this paper calls for a constructive and collaborative approach to enabling cultural facilities development within local government, and a re-conceptualization of the creative city planning agenda to include both the cultural products of creative industries and the diverse cultural experiences of non-profit and independent arts organizations beyond their economic and commercial development imperatives.

description: The distance between a quantum state and its closest state not having a certain property has been used to quantify the amount of correlations corresponding to that property. This approach allows a unified view of the various kinds of correlations present in a quantum system. In particular, using relative entropy as a distance measure, total correlations can be meaningfully separated in a quantum and a classical part thanks to an additive relation involving only distances between states. Here, we investigate a unified view of correlations using as distance measure the square norm, already used to define the so-called geometric quantum discord. We thus consider geometric quantifiers also for total and classical correlations finding, for a quite general class of bipartite states, their explicit expressions. We analyze the relationship among geometric total, quantum and classical correlations and we find that they do not satisfy anymore a closed additivity relation.

description: This paper responds to Exploring the dynamism between propositional complexity and error rate: a case study by Jordan Van Horn (this issue). In her study, Jordan Van Horn analyzes asynchronous email exchanges between a native and nonnative speaker of English utilizing three methods of analysis: error analysis, complexity analysis, and qualitative analysis. In triangulating the data, the author states that this mixed-methods approach can offer a better solution to limitations that arise as a result of employing only one method to analyze performance data. Indeed, interlanguage data often exhibits patterns of variability in complexity and accuracy in L2 learners (Spoelman & Verspoor, 2010). In order to better account for this variability and enhance our understanding of second language acquisition (SLA), the author incorporated Complex Dynamic Systems Theory (CDST) to guide her analysis. CDST facilitates the unification of the three methods of analysis since it posits L2 language as exhibiting the characteristics of complex systems and L2 language development as one that involves natural flux and variation (Verspoor, Lowie & van Dijk, 2008). A major contribution of this study was Van Horn’s finding of connected growers between complexity and accuracy. The CDST construct “connected growers” is defined by the author as linguistic subsystems that develop symbiotically as they interact. In other words, linguistic subsystems such as complexity and accuracy were found to have a positive correlation. This finding has major implications not only for our understanding of complex dynamic systems, but also, of SLA in particular, as during L2 linguistic performance, complexity and accuracy often compete with each other for cognitive resources and positive correlations between these two areas have been less common in the literature (Skehan, 2009).

description: Graphical model learning and inference are often performed using Bayesian techniques. In particular, learning is usually performed in two separate steps. First, the graph structure is learned from the data; then the parameters of the model are estimated conditional on that graph structure. While the probability distributions involved in this second step have been studied in depth, the ones used in the first step have not been explored in as much detail. In this paper, we will study the prior and posterior distributions defined over the space of the graph structures for the purpose of learning the structure of a graphical model. In particular, we will provide a characterisation of the behaviour of those distributions as a function of the possible edges of the graph. We will then use the properties resulting from this characterisation to define measures of structural variability for both Bayesian and Markov networks, and we will point out some of their possible applications.

description: This paper outlines a methodology for semi-parametric spatio-temporal modelling of data which is dense in time but sparse in space, obtained from a split panel design, the most feasible approach to covering space and time with limited equipment. The data are hourly averaged particle number concentration (PNC) and were collected, as part of the Ultrafine Particles from Transport Emissions and Child Health (UPTECH) project. Two weeks of continuous measurements were taken at each of a number of government primary schools in the Brisbane Metropolitan Area. The monitoring equipment was taken to each school sequentially. The school data are augmented by data from long term monitoring stations at three locations in Brisbane, Australia. Fitting the model helps describe the spatial and temporal variability at a subset of the UPTECH schools and the long-term monitoring sites. The temporal variation is modelled hierarchically with penalised random walk terms, one common to all sites and a term accounting for the remaining temporal trend at each site. Parameter estimates and their uncertainty are computed in a computationally efficient approximate Bayesian inference environment, R-INLA. The temporal part of the model explains daily and weekly cycles in PNC at the schools, which can be used to estimate the exposure of school children to ultrafine particles (UFPs) emitted by vehicles. At each school and long-term monitoring site, peaks in PNC can be attributed to the morning and afternoon rush hour traffic and new particle formation events. The spatial component of the model describes the school to school variation in mean PNC at each school and within each school ground. It is shown how the spatial model can be expanded to identify spatial patterns at the city scale with the inclusion of more spatial locations.

description: We study nucleon structure with positive and negative parities using a parity doublet model endowed with hidden local symmetry (HLS) with the objective to probe dense baryonic matter. The model -- that we shall refer to as "PDHLS model" for short -- allows a chiral-invariant mass of the nucleons unconnected to spontaneously broken chiral symmetry which comes out to be m_0 ~ 200 MeV at tree level from fitting to the decay width of the parity doubler, N(1535), to nucleon-pion and nucleon axial coupling g_A=1.267. The presence of a substantial m_0 that remains non-vanishing at chiral restoration presents a deep issue for the origin of the nucleon mass as well as will affect nontrivially the equation of state for dense baryonic matter relevant for compact stars. We construct a chiral perturbation theory at one-loop order and explore the phase structure of the model using renormalization group equations. We find a fixed point that corresponds exactly to the "dilaton limit" at which the HLS vector mesons decouple from the nucleons before reaching the vector manifestation fixed point. We suggest that cold baryonic system will flow to this limit as density increases toward that of chiral restoration.

description: A numerical study is presented to analyze the thermal mechanisms of unsteady, supersonic granular flow, by means of hydrodynamic simulations of the Navier-Stokes granular equations. For this purpose a paradigmatic problem in granular dynamics such as the Faraday instability is selected. Two different approaches for the Navier-Stokes transport coefficients for granular materials are considered, namely the traditional Jenkins-Richman theory for moderately dense quasi-elastic grains, and the improved Garzó-Dufty-Lutsko theory for arbitrary inelasticity, which we also present here. Both solutions are compared with event-driven simulations of the same system under the same conditions, by analyzing the density, the temperature and the velocity field. Important differences are found between the two approaches leading to interesting implications. In particular, the heat transfer mechanism coupled to the density gradient which is a distinctive feature of inelastic granular gases, is responsible for a major discrepancy in the temperature field and hence in the diffusion mechanisms.

Second language acquisition

description: In this special issue on Complex Dynamic Systems Theory (CDST), four empirical studies (by Ahmed, Choe, Ciriani Dean, and Van Horn) investigate interlanguage through a CDST perspective. As a way of extending the discussion on CDST, students in the Second Language Acquisition (SLA) doctoral seminar in the Applied Linguistics and TESOL Program at Teachers College, Columbia University were asked to select and discuss one empirical study published in the current issue, reflecting on the following: the theoretical viewpoint, the findings, the methodology, and/or the significance and implications. In response, three papers were submitted to the present forum.
Db-cAMP applied to the Red Nucleus in rat improves the regenerative response of the rubrospinal tract after cervical spinal cord injury
Creators: name: Lane, René
Publisher: name: University of British Columbia
Year: 2012

description: A high cervical injury to the rubrospinal tract (RST) generally results in cellular and nuclear atrophy of the rubral neurons, abortive axonal regeneration and eventual retraction from the forming injurious scar and enlarging cavity. The neuronal cell body response to axonal injury plays an important role in the failure of central nervous system (CNS) neurons to regenerate. Adult mammalian CNS neurons fail to re-express a variety of genes and signalling factors, such as cAMP, after axotomy that are seen at increased levels in regenerating peripheral neurons or in developing CNS neurons. By mimicking the sustained increase in cAMP levels, prior to or during an upper cervical (C3/4) crush injury of the dorsolateral funiculus in adult male Sprague-Dawley rats using the membrane permeant analogue dibutyryl cAMP (db-cAMP) near the vicinity of rubrospinal neurons, will enhance the regenerative cell body response in order to promote axonal sprouting or regeneration to and across the site of a spinal cord injury. Two experimental groups, acute and pre-treatment, were used. Both groups received either 25mM db-cAMP (treatment) or vehicle (control) solutions delivered via 14 day mini osmotic-pumps. The pretreated group had db-cAMP infused beginning one week prior to injury for two weeks while the acutely treated group received concurrent treatment with injury. The rubrospinal tract was anterogradedly traced with biotinylated dextran amine (BDA) for quantification purposes. Camera lucida like reconstructions (CLLRs) were created for enhanced visualization and density calculation of the RST. Changes in behaviour were assessed using the vertical exploration test. Application of db-cAMP to the RN in both the acute and pretreated groups increased the number of labelled rubrospinal fibres in the gray matter and proximal to the site of injury in comparison to the controls. Db-cAMP treatment did not reduce lesion sizes nor were there any visibly traced fibres caudal to the site of injury in any of the treatment groups. Unexpectedly, pre-treatment of db-cAMP conferred no advantages over acute treatment. Behavioural analysis of spontaneous forelimb usage as indicated by the vertical exploration test revealed no significant differences between any of the db-cAMP and control groups.
Amoxicillin with a side of aromatherapy: holistic therapies as a complementary approach to the treatment of pediatric conditions

Pediatrics

description: Contemporary parents are tech-savvy and seek online resources to supplement their children's health, with the feeling of truth equal to their pediatric provider. Many prefer to use organic products, are vaccine-hesitant, and seek out alternate and integrative therapies in conjunction with traditional medicine. Approximately 12 percent of children less than 18 years of age use some form of complementary therapy each year. These percentages are greater than 50 percent for children who have chronic, recurrent, or terminal conditions. As pediatric providers, it is imperative to understand how these therapies are being utilized so that providers can assist these parents in a more evidence-based manner. Many of these supplemental therapies can have adverse interactions, and it is important for the provider to be aware of them. Complementary therapies for commonly seen illnesses and symptoms such as otitis media, constipation, sore throat, eczema, cough, nausea, and vomiting will be discussed during the presentation, in addition to the therapy’s safety profile.

description: We define the class of high dimensional graph manifolds. These are compact smooth manifolds supporting a decomposition into finitely many pieces, each of which is diffeomorphic to the product of a torus with a finite volume hyperbolic manifold with toric cusps. The various pieces are attached together via affine maps of the boundary tori. We require all the hyperbolic factors in the pieces to have dimension at least 3. Our main goal is to study this class of graph manifolds from the viewpoint of rigidity theory. We show that, in high dimensions, the Borel conjecture holds for our graph manifolds. We also show that smooth rigidity holds within the class: two graph manifolds are homotopy equivalent if and only if they are diffeomorphic. We introduce the notion of irreducible graph manifolds, which form a subclass which has better coarse geometric properties. We establish some structure theory for finitely generated groups which are quasi-isometric to the fundamental group of an irreducible graph manifold: any such group has a graph of groups splitting with strong constraints on the edge and vertex groups. Finally, we prove that in every dimension >3 there exist examples of irreducible graph manifolds which do not support any locally CAT(0) metric.

description: Measles is a highly infectious, severe viral disease. The disease is targeted for global eradication; however, this result has proven challenging. In China, where countrywide vaccination coverage for the last decade has been above 95% (the threshold for measles elimination), measles continues to cause large epidemics. To diagnose factors contributing to the persistency of measles, here we develop a model-inference system to infer measles transmission dynamics in China. The model-inference system uses demographic and vaccination data for each year as model inputs to directly account for changing population dynamics (including births, deaths, migrations, and vaccination). In addition, it simultaneously estimates unobserved model variables and parameters based on incidence data. When fitted to yearly incidence data for the entire population, it is able to accurately estimate independent, out-of-sample age-specific incidence. Using this validated model-inference system, we are thus able to estimate epidemiological and demographical characteristics key to measles transmission during 1951–2004 for three key locations in China, including its capital Beijing. These characteristics include age-specific population susceptibility and incidence rates, the basic reproductive number (R0), reporting rate, population mixing intensity, and amplitude of seasonality. Key differences among the three sites reveal population and epidemiological characteristics crucial for understanding the current persistence of measles epidemics in China. We also discuss the implications our findings have for future elimination strategies.
Exploring the Dynamics of Willingness to Communicate in Written Communication: A Case Study

description: This paper investigates the dynamics of willingness to communicate (WTC) in written communication between a native and non-native speaker of English. Although research into WTC has identified topic as an interacting variable affecting L2 learners’ WTC during task performances (MacIntyre & Legatto, 2011) and classroom interactions (Cao, 2013), fewer studies have explored the nature of written WTC, its relationships with topics, as well as L2 writing development. This study addresses this gap by exploring the dynamism of WTC in writing from a Complex Dynamic Systems Theory (CDST) perspective. Through the employment of three methods—WTC analysis, complexity and accuracy analysis, and functional analysis—the findings suggest that WTC in written communication also reflects the characteristics of a dynamic system. Specifically, it fluctuates as the interlocutors organically move from one topic to the next. Results from the complexity and accuracy analysis and functional analysis provide further evidence to confirm that L2 development is a highly variable and nonlinear process. Overall, these findings lend support to the CDST perspective of interlanguage (IL) development, including dynamism in WTC and L2 writing development.
