description: The synthetic control (SC) method, a powerful tool for estimating average treatment effects (ATE), is increasingly popular in fields such as statistics, economics, political science and marketing. The SC is particularly suitable for estimating ATE with a single (or a few) treated unit(s), a fixed number of control units, and large pre and post-treatment periods (which we refer as ‘long panels’). To date, there has been no formal inference theory for synthetic control ATE estimator with long panels under general conditions. Existing work mostly use placebo tests for inference or some permutation methods when the post-treatment period is small. In this paper, we derive the asymptotic distribution of the synthetic control and modified synthetic control ATE estimators using projection theory. We show that a properly designed subsampling method can be used to obtain confidence intervals and conduct inference whereas the standard bootstrap cannot. Simulations and an empirical application that examines the effect of opening a physical showroom by an e-tailer demonstrate the usefulness of the modified synthetic control method in applications.

description: Abstract–Latent factor models are widely used to measure unobserved latent traits in social and behavioral sciences, including psychology, education, and marketing. When used in a confirmatory manner, design information is incorporated as zero constraints on corresponding parameters, yielding structured (confirmatory) latent factor models. In this article, we study how such design information affects the identifiability and the estimation of a structured latent factor model. Insights are gained through both asymptotic and nonasymptotic analyses. Our asymptotic results are established under a regime where both the number of manifest variables and the sample size diverge, motivated by applications to large-scale data. Under this regime, we define the structural identifiability of the latent factors and establish necessary and sufficient conditions that ensure structural identifiability. In addition, we propose an estimator which is shown to be consistent and rate optimal when structural identifiability holds. Finally, a nonasymptotic error bound is derived for this estimator, through which the effect of design information is further quantified. Our results shed lights on the design of large-scale measurement in education and psychology and have important implications on measurement validity and reliability.

description: FIR imaging of interacting galaxies allows locating even hidden sites of star formation and measuring of the relative strength of nuclear and extra-nuclear star formation. We want to resolve the star-forming sites in the nearby system of the Antennae. Thanks to the unprecedented sharpness and depth of the PACS camera onboard ESA's Herschel Space Observatory, it is possible for the first time to achieve a complete assessment of individual star-forming knots in the FIR with scan maps at 70, 100, and 160 um. We used clump extraction photometry and SED diagnostics to derive the properties related to star-forming activity. The PACS 70, 100, and 160 um maps trace the knotty structure of the most recent star formation along an arc between the two nuclei in the overlap area. The resolution of the starburst knots and additional multi-wavelength data allow their individual star formation history and state to be analysed. In particular, the brightest knot in the mid-infrared (K1), east of the southern nucleus, exhibits the highest activity by far in terms of dust heating and star formation rate, efficiency, and density. With only 2 kpc in diameter, this area has a 10-1000 um luminosity, which is as high as that of our Milky Way. It shows the highest deficiency in radio emission in the radio-to-FIR luminosity ratio and a lack of X-ray emission, classifying it as a very young complex. The brightest 100 and 160 um emission region (K2), which is close to the collision front and consists of 3 knots, also shows a high star formation density and efficiency and lack of X-ray emission in its most obscured part, but an excess in the radio-to-FIR luminosity ratio. This suggests a young stage, too, but different conditions in its interstellar medium. Our results provide important checkpoints for numerical simulations of interacting galaxies when modelling the star formation and stellar feedback.

description: In classical analysis of variance, dispersion is measured by considering squared distances of sample elements from the sample mean. We consider a measure of dispersion for univariate or multivariate response based on all pairwise distances between-sample elements, and derive an analogous distance components (DISCO) decomposition for powers of distance in $(0,2]$. The ANOVA F statistic is obtained when the index (exponent) is 2. For each index in $(0,2)$, this decomposition determines a nonparametric test for the multi-sample hypothesis of equal distributions that is statistically consistent against general alternatives.

"Harmonious disagreement" : Painters Eleven, abstraction, and the construction of Canadian modernism in the 1950s
Creators: name: Poon, Jessica
Publisher: name: University of British Columbia
Year: 2020

description: This dissertation is an examination of Painters Eleven and the complex network of national and international discourses on modern art, abstraction, and cultural politics that converged in Toronto in the 1950s. As a practical grouping of artists, Painters Eleven relied on self-marketing and self-branding strategies to gain recognition for themselves as well as for modern art in general in English Canada. Through a close consideration of Painters Eleven’s paradoxical idea of “harmonious disagreement,” I explore the group’s artistic practices, exhibition practices and pursuits, public and private statements, and their career successes and failures in order to highlight the idiosyncratic and contradictory mechanics of the group. I argue that the tensions between rhetoric and practice, cohesion and incohesion, and amicability and antagonism in the group’s art and discourse form a complex series of conflicts—as well as attempts to overcome or smooth out these conflicts or frictions—which are at the crux of Painters Eleven’s significance for abstract painting in midcentury English Canada. This study reframes the relationship between Painters Eleven and their reputations as pioneers of midcentury Canadian modernism by investigating how the group conceptualized, curated, and constructed their own reputations as avant-garde radicals. It also considers what their discourse and practice in Toronto can reveal about a transnational network of experimental abstraction in the era following the end of the Second World War, where contemporaneous artistic and critical activities in centers like Montreal, New York, and Paris were similarly preoccupied with advancing modern art as a national or international cultural force. I seek to understand how Painters Eleven attempted to mediate and reconcile the universalizing convictions of modernism and progress in art, science, and technology with the increasingly urgent concern for national identity in Canada during this period. By examining Painters Eleven through the lens of a postwar cosmopolitan ethos and vision, this inquiry offers new insight into their significance for the construction of Canadian culture in the postwar era.

description: We consider the effect of modified gravity on the growth of large-scale structures at second order in perturbation theory. We show that modified gravity models changing the linear growth rate of fluctuations are also bound to change, although mildly, the mode coupling amplitude in the density and reduced velocity fields. We present explicit formulae which describe this effect. We then focus on models of modified gravity involving a scalar field coupled to matter, in particular chameleons and dilatons, where it is shown that there exists a transition scale around which the existence of an extra scalar degree of freedom induces significant changes in the coupling properties of the cosmic fields. We obtain the amplitude of this effect for realistic dilaton models at the tree-order level for the bispectrum, finding them to be comparable in amplitude to those obtained in the DGP model.

description: We introduce a new shrinkage prior on function spaces, called the functional horseshoe (fHS) prior, that encourages shrinkage toward parametric classes of functions. Unlike other shrinkage priors for parametric models, the fHS shrinkage acts on the shape of the function rather than inducing sparsity on model parameters. We study the efficacy of the proposed approach by showing an adaptive posterior concentration property on the function. We also demonstrate consistency of the model selection procedure that thresholds the shrinkage parameter of the fHS prior. We apply the fHS prior to nonparametric additive models and compare its performance with procedures based on the standard horseshoe prior and several penalized likelihood approaches. We find that the new procedure achieves smaller estimation error and more accurate model selection than other procedures in several simulated and real examples. Supplementary materials for this article, which contain additional simulated and real data examples, MCMC diagnostics, and proofs of the theoretical results, are available online.

description: Inverse probability weighting (IPW) is widely used in empirical work in economics and other disciplines. As Gaussian approximations perform poorly in the presence of “small denominators,” trimming is routinely employed as a regularization strategy. However, ad hoc trimming of the observations renders usual inference procedures invalid for the target estimand, even in large samples. In this article, we first show that the IPW estimator can have different (Gaussian or non-Gaussian) asymptotic distributions, depending on how “close to zero” the probability weights are and on how large the trimming threshold is. As a remedy, we propose an inference procedure that is robust not only to small probability weights entering the IPW estimator but also to a wide range of trimming threshold choices, by adapting to these different asymptotic distributions. This robustness is achieved by employing resampling techniques and by correcting a non-negligible trimming bias. We also propose an easy-to-implement method for choosing the trimming threshold by minimizing an empirical analogue of the asymptotic mean squared error. In addition, we show that our inference procedure remains valid with the use of a data-driven trimming threshold. We illustrate our method by revisiting a dataset from the National Supported Work program. Supplementary materials for this article are available online.

description: We present an analytical computation of the asymptotic temporal behavior of the information geometric complexity (IGC) of finite-dimensional Gaussian statistical manifolds in the presence of microcorrelations (correlations between microvariables). We observe a power law decay of the IGC at a rate determined by the correlation coefficient. It is found that microcorrelations lead to the emergence of an asymptotic information geometric compression of the statistical macrostates explored by the system at a faster rate than that observed in absence of microcorrelations. This finding uncovers an important connection between (micro)-correlations and (macro)-complexity in Gaussian statistical dynamical systems.

description: We study Maker-Breaker games played on the edge set of a random graph. Specifically, we consider the random graph process and analyze the first time in a typical random graph process that Maker starts having a winning strategy for his final graph to admit some property $\mP$. We focus on three natural properties for Maker's graph, namely being $k$-vertex-connected, admitting a perfect matching, and being Hamiltonian. We prove the following optimal hitting time results: with high probability Maker wins the $k$-vertex connectivity game exactly at the time the random graph process first reaches minimum degree $2k$; with high probability Maker wins the perfect matching game exactly at the time the random graph process first reaches minimum degree $2$; with high probability Maker wins the Hamiltonicity game exactly at the time the random graph process first reaches minimum degree $4$. The latter two statements settle conjectures of Stojaković and Szabó.

description: A toy-model quantum system is proposed. At a given integer $N$ it is defined by the pair of $N$ by $N$ real matrices $(H,Θ)$ of which the first item $H$ specifies an elementary, diagonalizable non-Hermitian Hamiltonian $H \neq H^\dagger$ with the real and explicit spectrum given by the zeros of the $N-$th Chebyshev polynomial of the first kind. The second item $Θ\neq I$ must be (and is being) constructed as the related Hilbert-space metric which specifies the (in general, non-unique) physical inner product and which renders our toy-model Hamiltonian selfadjoint, i.e., compatible with the Dieudonne equation $H^\dagger Θ= Θ\,H$. The elements of the (in principle, complete) set of the eligible metrics are then constructed in closed band-matrix form. They vary with our choice of the $N-$plet of optional parameters, $Θ=Θ(\vecκ)>0$ which must be (and are being) selected as lying in the positivity domain of the metric, $\vecκ \in {\cal D}^{(physical)}$.

design for emotion
computer-aided sketching

description: Merging emotional value into products has become an essential strategy for increasing a product’s competitive edge in the consumer market. Indeed, this approach instills emotional value into products, to satisfy human emotional needs. Combined with this is the fact that designers usually work outside their design office using pen and paper, since ideas are usually stimulated. Yet, designers lack mobile computer-aided sketching (CAS) tools which truly link paper-based sketching with computer-based 3D modelling tools. As a step in this direction, this poster presents a framework that extends CAS technology to cameraphones. Furthermore, this framework is capable of providing emotional guidance about a form concept to satisfy the emotional needs of the customer, directly on cameraphones. A proof-of-concept tool has been implemented and evaluated. Preliminary evaluation results with design engineers in the cosmetic cases industry, indicate the positive impact that technology based on the framework developed will have on DFe in practice.
The many faces of the unreliable narrator : an analysis and typology of young adult novels and their narrators
Creators: name: Hall, Lacey

Year: 2018

description: This thesis examines the style of unreliable narration, through the analysis of three young adult novels: The Perks of Being a Wallflower by Stephen Chbosky, We Were Liars by E. Lockhart, and Challenger Deep by Neal Shusterman. Drawing on Theresa Heyd’s theories on detection and classification of unreliable narration using the Gricean maxims, this study sets out to demonstrate how unreliable narration is defined and to highlight the degree of intentionality each narrator possesses. This study also gives attention to the real author of each text, in order to combat the outdated and over studied ‘implied author’ previous research has focused on. This research highlights the narrative technique, while adding to the limited number of resources available on unreliable narration within children’s literature.

description: Expectation propagation is a general prescription for approximation of integrals in statistical inference problems. Its literature is mainly concerned with Bayesian inference scenarios. However, expectation propagation can also be used to approximate integrals arising in frequentist statistical inference. We focus on likelihood-based inference for binary response mixed models and show that fast and accurate quadrature-free inference can be realized for the probit link case with multivariate random effects and higher levels of nesting. The approach is supported by asymptotic calculations in which expectation propagation is seen to provide consistent estimation of the exact likelihood surface. Numerical studies reveal the availability of fast, highly accurate and scalable methodology for binary mixed model analysis.

description: We study the effect of electron-electron interactions on the charge and spin structures of a Quantum Hall strip in a triangularly confined potential. We find that the strip undergoes a spin-unpolarized to spin-polarized transition as a function of magnetic field perpendicular to the strip. For sharp confinements the spin-polarization transition is spontaneous and first develops at the softer side of the triangular potential which shows up as an "eye-structure" in the electron dispersion. For sufficiently weak confinements this spin-polarization transition is preceded by a charge reconstruction of a single spin species, which creates a spin-polarized strip of electrons with a width of the order of the magnetic length detached from the rest of the system. Relevance of our findings to the recent momentum resolved tunneling experiments is also discussed.

description: There are a wide range of opportunities for and approaches to developing and customizing data visualization support services in academic libraries; however, practitioners interested in exploring current approaches are constrained by the lack of a mature body of literature to consult for inspiration, caution, and best practices. This chapter presents a case study of the implementation of a data visualization space and revised data visualization services in an academic library-based digital scholarship center. A brief summary of data support and data visualization services in the academic library landscape will be outlined, followed by an institutional and organizational profile. Rationale for physical infrastructure and equipment purchases will be provided. Initial lessons learned from iterative design and equipment selection conversations will be described. Provisional access, instructional, evaluation, and outreach plans will be shared. Next steps for enhancing the data visualization space and its affiliated services will be proposed.

description: We have investigated the effects of ozone treatment on graphene by Raman scattering. Sequential ozone short-exposure cycles resulted in increasing the $p$ doping levels as inferred from the blue shift of the 2$D$ and $G$ peak frequencies, without introducing significant disorder. The two-phonon 2$D$ and 2$D'$ Raman peak intensities show a significant decrease, while, on the contrary, the one-phonon G Raman peak intensity remains constant for the whole exposure process. The former reflects the dynamics of the photoexcited electrons (holes) and, specifically, the increase of the electron-electron scattering rate with doping. From the ratio of 2$D$ to 2$D$ intensities, which remains constant with doping, we could extract the ratio of electron-phonon coupling parameters. This ratio is found independent on the number of layers up to ten layers. Moreover, the rate of decrease of 2$D$ and 2$D'$ intensities with doping was found to slowdown inversely proportional to the number of graphene layers, revealing the increase of the electron-electron collision probability.

description: Direct photon emission in heavy-ion collisions is calculated within a relativistic micro+macro hybrid model and compared to the microscopic transport model UrQMD. In the hybrid approach, the high-density part of the collision is calculated by an ideal 3+1-dimensional hydrodynamic calculation, while the early (pre-equilibrium-) and late (rescattering-) phase are calculated with the transport model. We study both models with Au+Au-collisions at \sqrt{s_NN} = 200 GeV and compare the results to experimental data published by the PHENIX collaboration.

description: Permutation $p$-values have been widely used to assess the significance of linkage or association in genetic studies. However, the application in large-scale studies is hindered by a heavy computational burden. We propose a geometric interpretation of permutation $p$-values, and based on this geometric interpretation, we develop an efficient permutation $p$-value estimation method in the context of regression with binary predictors. An application to a study of gene expression quantitative trait loci (eQTL) shows that our method provides reliable estimates of permutation $p$-values while requiring less than 5% of the computational time compared with direct permutations. In fact, our method takes a constant time to estimate permutation $p$-values, no matter how small the $p$-value. Our method enables a study of the relationship between nominal $p$-values and permutation $p$-values in a wide range, and provides a geometric perspective on the effective number of independent tests.

description: The red seaweed Asparagopsis taxiformis (phylum Rhodophyta, class Florideophyceae) is a widespread marine macroalga that in recent years, has been the target of significant research into its environmental, health, and economic applications. In particular, A. taxiformis produces a range of secondary metabolites and other natural products that underlines its relative importance. However, similar to other rhodophytes with limited available genetic resources, the genetic mechanisms that drive its metabolic pathways remain poorly investigated. Thus, the aim of this PhD research was to develop genetic resources and investigate the metabolic pathways and regulatory elements of rhodophytes, including A. taxiformis. We further aimed to develop tools to utilise these resources to further facilitate future research into rhodophyte genetics and metabolomics.

description: Percutaneous coronary interventions (PCIs) are nonsurgical procedures to open blocked blood vessels to the heart, frequently using a catheter to place a stent. The catheter can be inserted into the blood vessels using an artery in the groin or an artery in the wrist. Because clinical trials have indicated that access via the wrist may result in fewer post procedure complications, shortening the length of stay, and ultimately cost less than groin access, adoption of access via the wrist has been encouraged. However, patients treated in usual care are likely to differ from those participating in clinical trials, and there is reason to believe that the effectiveness of wrist access may differ between males and females. Moreover, the choice of artery access strategy is likely to be influenced by patient or physician unmeasured factors. To study the effectiveness of the two artery access site strategies on hospitalization charges, we use data from a state-mandated clinical registry including 7,963 patients undergoing PCI. A hierarchical Bayesian likelihood-based instrumental variable analysis under a latent index modeling framework is introduced to jointly model outcomes and treatment status. Our approach accounts for unobserved heterogeneity via a latent factor structure, and permits nonparametric error distributions with Dirichlet process mixture models. Our results demonstrate that artery access in the wrist reduces hospitalization charges compared to access in the groin, with a higher mean reduction for male patients.

Analysis and optimization of communication technologies for smart grid applications

description: Several communication technologies including IEEE 802.15.4g, world-wide interoperability for microwave access (WiMAX), and power line communication (PLC) have been suggested for smart grid implementation. As the successful arrival of smart grid traffic within their latency requirement is essential for the correct operation of the power grid, we focus on the optimization of different features of these communication technologies and also the development of aspects of an efficient network architecture such that the reliability requirement associated with smart grid traffic can best be assured. We first investigate an optimized configuration of WiMAX features, in particular, the choice of frame duration, type-of-service to traffic mapping and uplink and downlink allocations, under what we call the “profile configuration”. We also devise inter-class and intra-class scheduling solutions in order to prioritize time-critical traffic within both base station and customer premises equipments. We then evaluate the performance of the developed WiMAX profile configuration and scheduling scheme through our newly developed WiGrid (WiMAX for Smart Grid) module. From the performed simulations, we conclude that the proposed configurations for the WiMAX features can ensure the satisfaction of the reliability requirement. Next, we design advanced metering infrastructures (AMIs) based on the characteristics of the PLC and the IEEE 802.15.4g technologies. We use intermediary data collectors, known as data acquisition points (DAPs), in order to efficiently collect traffic from smart meters and forward them to the utility control center. We formulate an optimization platform for efficiently placing DAPs on top of the existing utility poles or transformers, in such a way that the required reliability for smart grid traffic is ensured and also the installation cost is minimized. In order to address the QoS requirements, we derive the latency based on the characteristics of the medium access control schemes of each of these technologies. Since finding the optimal DAP locations is an integer programming problem and NP-hard, we develop several heuristic algorithms for efficiently placing DAPs within large-scale scenarios. We observe that the DAP placement algorithms, proposed here for large-scale scenarios, return near-optimal results within a much shorter time, than that of the IBM CPLEX software for small scenarios.

description: Brief-Editionen sind in vielerlei Hinsicht ein unerlässliches Hilfsmittel für die (historische) Forschung. Gerade weil Briefe ein höchst subjektives Ausdrucksmedium sind, enthalten sie oftmals wertvolle Informationen, die für das Verständnis größerer Zusammenhänge essentiell sein können. Doch um ihr volles Potential entfalten zu können, müssten sie leicht zugänglich sein. Dabei liegen die allermeisten Editionen ausschließlich in gedruckter Form vor, nur neuere Vorhaben publizieren wenigstens teilweise digital.

Der Forscherin oder dem Forscher entgehen im Zweifelsfall wichtige Schriftzeugnisse, weil sie sie schlichtweg nicht finden. Oder um es mit Goethe zu sagen: „Man erblickt nur, was man schon weiß und versteht.“ Es stellt sich also die Frage, wie man diese zwischen Buchdeckel gepressten Schätze heben und der Forschung zugänglich machen kann. OCR-gestützte Retrodigitalisierung von Volltexten kritischer Editionen ist hier qualitativ zumeist noch nicht ausreichend. Erschwerend kommt hinzu, dass diese nicht-semantisch ist – und bei urheberrechtlich geschützten Werken in aller Regel völlig unmöglich.

description: A fundamental challenge in observational causal inference is that assumptions about unconfoundedness are not testable from data. Assessing sensitivity to such assumptions is therefore important in practice. Unfortunately, some existing sensitivity analysis approaches inadvertently impose restrictions that are at odds with modern causal inference methods, which emphasize flexible models for observed data. To address this issue, we propose a framework that allows (1) flexible models for the observed data and (2) clean separation of the identified and unidentified parts of the sensitivity model. Our framework extends an approach from the missing data literature, known as Tukey’s factorization, to the causal inference setting. Under this factorization, we can represent the distributions of unobserved potential outcomes in terms of unidentified selection functions that posit a relationship between treatment assignment and unobserved potential outcomes. The sensitivity parameters in this framework are easily interpreted, and we provide heuristics for calibrating these parameters against observable quantities. We demonstrate the flexibility of this approach in two examples, where we estimate both average treatment effects and quantile treatment effects using Bayesian nonparametric models for the observed data.
David and Goliaths: Image of the Enemy in Early Imperial Russian Military Sermons
Creators: name: Ivanov, Andrey V.
Publisher: name: University of Notre Dame
Year: 2023

description: This article explores the content of wartime sermons in eighteenth-century Russia, delivered by the Orthodox bishops during the pivotal military conflicts of early imperial period. Apart from communicating war aims and current events to the laity, these sermons also presented an image of the enemy to the masses. This imagery manifested bishops’ support for the Petrine and Catherinian cultural opening to the West, on the one hand, while promoting a myth of an existential antagonism against the Ottoman South, on the other. Unlike their seventeenth-century predecessors, eighteenth-century sermons avoided the stereotypes of heterodoxy or heresy when describing Russia’s Western enemies, preferring instead the language of just or unjust wars, protection of European neighbors or the metaphor of David facing titanic Goliaths. The non-sectarian imagery, however, did not extend to Islam. Sermons of the Russo-Ottoman wars presented the conflict as a purely religious and Russia’s involvement as a holy war.

description: Pressure relief valve (PRV) is one of the hydraulic devices used to protect water distribution systems (WDS) from pressure surges due to its efficiency and feasibility in application. The performance of PRV is determined by several parameters that include design parameters, system parameters and operation parameters. A comprehensive pipeline optimization transient flow model using GA is originally developed to determine the optimal all PRV parameters by minimizing the difference between the maximum and the minimum pressure heads in WDS. The performance of the model is tested by comparing the results with the corresponding ones from literature. The model has been applied to a real WDS of El-Mostakbal City, Egypt. The results show that controlling of abnormal pressure surges in WDS can be achieved by using optimal selection of all PRV parameters.

description: Time-varying networks are fast emerging in a wide range of scientific and business applications. Most existing dynamic network models are limited to a single-subject and discrete-time setting. In this article, we propose a mixed-effect network model that characterizes the continuous time-varying behavior of the network at the population level, meanwhile taking into account both the individual subject variability as well as the prior module information. We develop a multistep optimization procedure for a constrained likelihood estimation and derive the associated asymptotic properties. We demonstrate the effectiveness of our method through both simulations and an application to a study of brain development in youth. Supplementary materials for this article are available online.
