title: Assessment of Motor Proficiency Levels in Children in Saudi Arabia
Creators: name: Al-Thumali, Fahad Jameel M

Subjects: subject: Motor development, Children
subject: Bruininks-Oseretsky Test of Motor Proficiency (BOT-2)
subject: Child development, Saudia Arabia

description: Assessing children’s motor development is important for determining their developmental levels and needs in order to promote their motor skills. Differing environmental and cultural backgrounds can impact upon children’s motor development, and thus need to be taken into account in motor assessments. This study aimed to provide a comprehensive overview of the motor development levels of children in Saudi Arabia using the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). The investigation included both genders (males and females) at three school grade levels (1st, 3rd, 5th) from two residential areas (urban and rural). Moreover, the study investigated the effects of gender, grade, and residence on the performance of a sample of 188 Saudi children. These results were compared to BOT-2 norms from a United States sample. Furthermore, this study examined the possibility of using BOT-2 in Saudi society (objectivity, reliability, and validity). A quantitative research paradigm was used in the study to achieve the study’s objectives. One-sample-t-test was utilised to identify any significant differences between the study groups and BOT-2 norms in the subtest point scores. A three-way analysis of variance (ANOVA) was performed to determine any effect of the independent variables (gender, grade, and residential area) on the dependent variables (motor-area composite scores). Lastly, several statistical methods were used to examine the objectivity, reliability, and validity of using BOT-2 with Saudi children.
Causal inference with multi-state models - estimands and estimators of the population-attributable fraction

description: The population-attributable fraction (PAF) is a popular epidemiological measure for the burden of a harmful exposure within a population. It is often interpreted causally as proportion of preventable cases after an elimination of exposure. Originally, the PAF has been defined for cohort studies of fixed length with a baseline exposure or cross-sectional studies. An extension of the definition to complex time-to-event data is not straightforward. We revise the proposed approaches in literature and provide a clear concept of the PAF for these data situations. The conceptualization is achieved by a proper differentiation between estimands and estimators as well as causal effect measures and measures of association.

description: A large number of modern video background modeling algorithms deal with computational costly minimization problems that often need parameter adjustments. While in most cases spatial and temporal constraints are added artificially to the minimization process, our approach is to exploit Dynamic Mode Decomposition (DMD), a spectral decomposition technique that naturally extracts spatio-temporal patterns from data. Applied to video data, DMD can compute background models. However, the original DMD algorithm for background modeling is neither efficient nor robust. In this paper, we present an equivalent reformulation with constraints leading to a more suitable decomposition into fore- and background. Due to the reformulation, which uses sparse and low-dimensional structures, an efficient and robust algorithm is derived that computes accurate background models. Moreover, we show how our approach can be extended to RGB data, data with periodic parts, and streaming data enabling a versatile use.

description: We consider a class of algebraic dynamical systems introduced by Kitchens and Schmidt. Under a weak finiteness condition -- the Descending Chain Condition -- the dual modules have finite presentations. Using methods from commutative algebra we show how the dynamical properties of the system may be deduced from the Fitting ideals of a finite free resolution of the finitely presented module. The entropy and expansiveness are shown to depend only on the first Fitting ideal (and certain multiplicity data) which gives an easy computation: in particular, no syzygy modules need to be computed. For `square' presentations (in which the number of generators is equal to the number of relations) all the dynamics is visible in the first Fitting ideal and certain multiplicity data, and we show how the dynamical properties and periodic point behaviour may be deduced from the determinant of the matrix of relations.

description: We study the orthogonal projections of symplectic balls in $\mathbb{R}^{2n}$ on complex subspaces. In particular we show that these projections are themselves symplectic balls under a certain complexity assumption. Our main result is a refinement of a recent very interesting result of Abbondandolo and Matveyev extending the linear version of Gromov's non-squeezing theorem. We use a conceptually simpler approach where the Schur complement of a matrix plays a central role.

description: This thesis aims to provide an in-depth understanding of the nature of American Depositary Receipts (ADRs) from emerging markets as a viable investment vehicle. In this research, Brazil, Russia, India and China (the BRICs) are used as a representative sample of worldwide emerging markets. The motivation of this thesis derives from empirical evidence of large ADR price spreads which violates the law of one price (LOP). Unlike prior research which attempted to identify explanatory factors for this seemingly pricing puzzle in ADR markets, this thesis seeks to answer the research question: Are emerging market ADRs different securities from their underlying stocks? The overarching research objective is to determine whether the pricing mechanism of ADRs from emerging markets is theoretically supported by the LOP, and if investors can potentially obtain at least similar diversification benefits of ADR investments compared to directly investing in underlying stocks.

description: Given a combinatorial (semi-)model category $M$ and a set of morphisms $C$, we establish the existence of a semi-model category $L_C M$ satisfying the universal property of the left Bousfield localization in the category of semi-model categories. Our main tool is a semi-model categorical version of a result of Jeff Smith, that appears to be of independent interest. Our main result allows for the localization of model categories that fail to be left proper. We give numerous examples and applications, related to the Baez-Dolan stabilization hypothesis, localizations of algebras over operads, chromatic homotopy theory, parameterized spectra, $C^*$-algebras, enriched categories, dg-categories, functor calculus, and Voevodsky's work on radditive functors.

An asymptotic Peskun ordering and its application to lifted samplers

description: A Peskun ordering between two samplers, implying a dominance of one over the other, is known among the Markov chain Monte Carlo community for being a remarkably strong result. It is however also known for being a result that is notably difficult to establish. Indeed, one has to prove that the probability to reach a state $\mathbf{y}$ from a state $\mathbf{x}$, using a sampler, is greater than or equal to the probability using the other sampler, and this must hold for all pairs $(\mathbf{x}, \mathbf{y})$ such that $\mathbf{x} \neq \mathbf{y}$. We provide in this paper a weaker version that does not require an inequality between the probabilities for all these states: essentially, the dominance holds asymptotically, as a varying parameter grows without bound, as long as the states for which the probabilities are greater than or equal to belong to a mass-concentrating set. The weak ordering turns out to be useful to compare lifted samplers for partially-ordered discrete state-spaces with their Metropolis--Hastings counterparts. An analysis in great generality yields a qualitative conclusion: they asymptotically perform better in certain situations (and we are able to identify them), but not necessarily in others (and the reasons why are made clear). A quantitative study in a specific context of graphical-model simulation is also conducted.

description: To investigate the effect of feedback from active galactic nuclei (AGN) on their surrounding medium, we study the diffuse X-ray emission from galaxy groups and clusters by coupling the Astrophysical Plasma Emission Code (APEC) with the cosmological hydrodynamic simulation involving AGN feedback. We construct a statistical sample of synthetic Chandra X-ray photon maps to observationally characterize the effect of AGN on the ambient medium. We show that AGN are effective in displacing the hot X-ray emitting gas from the centers of groups and clusters, and that these signatures remain evident in observations of the X-ray surface brightness profiles.

The classical double copy in curved spacetimes: Perturbative Yang-Mills from the bi-adjoint scalar

description: We formulate a version of the double copy for classical fields in curved spacetimes. We provide a correspondence between perturbative solutions to the bi-adjoint scalar equations and those of the Yang-Mills equations in position space. At the linear level, we show that there exists a map between these solutions for maximally symmetric spacetime backgrounds, that provides every Yang-Mills solution by the action of an appropriate differential operator on a bi-adjoint scalar solution. Given the existence of a linearized map, we show that it is possible to cast the solutions of the Yang-Mills equations at arbitrary perturbation order in terms of the corresponding bi-adjoint scalar solutions. This all-order map is reminiscent of the flat space BCJ double copy, and works for any curved spacetime where the perturbative expansion holds. We show that these results have the right flat space limit, and that the correspondence is agnostic to the choice of gauge.

description: We introduce a one-dimensional sandpile model which incorporates particle inertia. The inertial dynamics are governed by a new parameter which, as it passes through a threshold value, alters the toppling dynamics in such a way that the system no longer evolves to a self-organized critical state. A range of mean-field theories based on a kinetic equation approach is presented which confirm the numerical findings. We conclude by considering the physical applications of this model, particularly with reference to recent experimental results.

description: We complete the procedure of extracting parton distribution functions (PDFs) using large momentum effective theory (LaMET) at leading power accuracy in the hadron momentum. We derive a general factorization formula for the quasi PDFs in the presence of mixing, and give the corresponding hard matching kernel at $\mathcal O(α_s)$, both for the unpolarized and for the polarized quark and gluon quasi-PDFs. Our calculation is performed in a regularization-independent momentum subtraction scheme. The results allow us to match the nonperturbatively renormalized quasi-PDFs to normal PDFs in the presence of mixing, and therefore can be used to extract flavor-singlet quark PDFs as well as gluon PDFs from lattice simulations.

By analysing the teacher’s diary and following step by step the way she addressed a science intervention with the main intention to build on children’s ideas, interests, and questions, we aimed to develop knowledge of the teacher’s role to science learning in early childhood education, when free and guided play activities are implemented and mutually interchanged. The results indicated four main roles, which are enacted in various contexts by the teacher, and four resources she drew upon for addressing the integration of science learning with play.

description: Gaussian random matrix ensembles defined over the tangent spaces of the large families of Cartan's symmetric spaces are considered. Such ensembles play a central role in mesoscopic physics since they describe the universal ergodic limit of disordered and chaotic single particle systems. The generating function for the spectral correlations of each ensemble is reduced to an integral over a Riemannian symmetric superspace in the limit of large matrix dimension. Such a space is defined as a pair (G/H,M_r) where G/H is a complex-analytic graded manifold homogeneous with respect to the action of a complex Lie supergroup G, and M_r is a maximal Riemannian submanifold of the support of G/H.

description: This study focuses on the analysis of the knowledge of the expert teachers of technology. By knowledge we mean the prediction of the time required to solve exercises of technical drawing. By a methodology built from the comparison between time predicted by the teachers and the time really needed by pupils to solve the exercises, we characterized the process of temporal prediction of the teachers. This characterization of the concept prediction, regarding temporality, will allow conceiving, in the future, protocols of training for the novice teachers of technology.

description: Fluid-structure simulations of slender inextensible filaments in a viscous fluid are often plagued by numerical stiffness. Recent coarse-graining studies have reduced the computational requirements of simulating such systems, though have thus far been limited to the motion of planar filaments. In this work we extend such frameworks to filament motion in three dimensions, identifying and circumventing coordinate-system singularities introduced by filament parameterisation via repeated changes of basis. The resulting methodology enables efficient and rapid study of the motion of flexible filaments in three dimensions, and is readily extensible to a wide range of problems, including filament motion in confined geometries, large-scale active matter simulations, and the motility of mammalian spermatozoa.

description: Rice is a crucial crop to meet global food demands, therefore, it is necessary to develop rapid, efficient and inexpensive methods for screening mutants of important genes in molecular breeding. In this research, a simple microfluidic chip-integrated one-step polymerase chain reaction (PCR) and high-resolution melting (HRM) analysis were designed for the rapid screening of rice mutants. In order to complete the above processes, we also installed a self-developed functional instrument integrated with a temperature control system and a fluorescence detection department. This microfluidic platform was validated by analysing genes related to insect resistance, phenotype and yield of two important varieties of rice, Oryza sativa L. ssp. japonica. and Oryza sativa L. ssp. indica (93–11). The results showed that the platform could detect single-nucleotide mutations between the wild and the mutant rice plants in 1 h and the accuracy was consistent with gene sequencing regarded as the golden standard of the mutants screening. Compared to the traditional method (requiring approximately 3 h), this platform can distinguish mutants from wild types more rapidly. This system is a simple, integrated, disposable and low-cost tool for high-throughput screening of mutants in molecular breeding. More important, this portable instrument can be used as a point-of-care platform for nucleic acid diagnostics in many scientific fields.

description: The dynamical behavior of the column that made up binary granular beads is investigated systematically by tracking the displacement of particles in the collapse process. An experimental setup is first devised to control the quasi-static collapse of a granular column, and then observe the trajectories of tracer particles by using an industrial camera controlled by the image acquisition program. It is found that there exist two zones in column: a sliding region in which particles are moving in a layered structure; a static region within which particles are stationary. According to this analytical result, a dynamical model is developed to predict the trajectory evolution of particles in the space-time. The calculating result for the trajectories of particles on the selected layers is well consistent with the experimental observation.

description: Structure I and II gas hydrates were observed in the same sediment cores of a mud volcano in the Kukuy Canyon, Lake Baikal. The sII gas hydrate contained about 13-15% of ethane, whereas the sI gas hydrate contained about 1-5% of ethane and placed beneath the sII gas hydrate. We measured isotopic composition of dissociation gas from both type gas hydrates and dissolved gas in pore water. We found that ethane δD of sI gas hydrate (from -196 to -211 ‰) was larger than that of sII (from -215 to -220 ‰), whereas methane δ13C, methane δD and ethane δD in both hydrate structures were almost the same. δ13C of methane and ethane in gas hydrate seemed several permil smaller than those in pore water. These results support the following idea that the current gas in pore water is not the source of these gas hydrates of both structures. Isotopic data also provide useful information how the “double structure” gas hydrates formed.

We propose a model synthesising the full version of Toulmin’s argumentation scheme and a classification of the source of authority upon which the argumentation draws to identify the diverse ways that the teacher communicates the acceptable aspects of a mathematical argument. An exemplar application of the model to the collective argumentation of a class of four-year old children is presented.

Taking into account research on model-based learning in science education, we investigated 11-12 year-old students’ conceptions about energy in a university laboratory using a hydraulics bench intended for training Engineering students. The original set-up was modified to simulate a hydroelectric power station. Participants were given a list of activities and worked in groups. Their discussions were recorded and later debriefed. Field notes were also taken. Research data and results are presented and discussed.

description: This dissertation contains two parts. The first part introduces the first class of perfect sampling algorithms for the steady-state distribution of multi-server queues in which the arrival process is a general renewal process and the service times are independent and identically distributed (iid); the first-in-first-out FIFO GI/GI/c queue with 2 <= c < 1. Two main simulation algorithms are given in this context, where both of them are built on the classical dominated coupling from the past (DCFTP) protocol. In particular, the first algorithm uses a coupled multi-server vacation system as the upper bound process and it manages to simulate the vacation system backward in time from stationarity at time zero. The second algorithm utilizes the DCFTP protocol as well as the Random Assignment (RA) service discipline. Both algorithms have finite expected termination time with mild moment assumptions on the interarrival time and service time distributions. Our methods are also extended to produce exact simulation algorithms for Fork-Join queues and infinite server systems.
      The second part presents general principles for the design and analysis of unbiased Monte Carlo estimators in a wide range of settings. The estimators possess finite work-normalized variance under mild regularity conditions. We apply the estimators to various applications including unbiased steady-state simulation of regenerative processes, unbiased optimization in Sample Average Approximations and distribution quantile estimation.

description: Using a hydrodynamic lattice-gas model, we study interface growth in a binary fluid with various concentrations of surfactant. We find that the interface is smoothed by small concentrations of surfactant, while microemulsion droplets form for large surfactant concentrations. To assist in determining the stability limits of the interface, we calculate the change in the roughness and growth exponents $α$ and $β$ as a function of surfactant concentration along the interface.

Exact and Approximate Methods for Machine Translation Decoding
Creators: Chang, Yin-Wen

Subjects: Computer science

description: Statistical methods have been the major force driving the advance of machine translation in recent years. Complex models are designed to improve translation performance, but the added complexity also makes decoding more challenging. In this thesis, we focus on designing exact and approximate algorithms for machine translation decoding. More specifically, we will discuss the decoding problems for phrase-based translation models and bidirectional word alignment.
      The techniques explored in this thesis are Lagrangian relaxation and local search. Lagrangian relaxation based algorithms give us exact methods that have formal guarantees while being efficient in practice. We study extensions to Lagrangian relaxation that improve the convergence rate on machine translation decoding problems. The extensions include a tightening technique that adds constraints incrementally, optimality-preserving pruning to manage the search space size and utilizing the bounding properties of Lagrangian relaxation to develop an exact beam search algorithm. In addition to having the potential to improve translation accuracy, exact decoding deepens our understanding of the model that we are using, since it separates model errors from optimization errors.
      This leads to the question of designing models that improve the translation quality. We design a syntactic phrase-based model that incorporates a dependency language model to evaluate the fluency level of the target language. By employing local search, an approximate method, to decode this richer model, we discuss the trade-off between the complexity of a model and the decoding efficiency with the model.
Ex-Communist Party Choices and the Electoral Success of the Radical Right in Central and Eastern Europe

description: What explains the proletarization (the increasing embrace by the blue-collar constituencies) of the radical right vote in the countries of post-Communist Europe? I argue that the centrist shift of the ex-Communist left parties along the economic policy dimension drives the electoral success of radical right parties in the region. I show that the programmatic shift of the ex-Communist left parties (as instrumented by the implementation of austerity reforms) opened up their traditional blue-collar constituencies to the redistributive appeals of the radical right parties. I test my argument using several different approaches. First, I examine the relationship between the support for the radical right parties and the ex-Communist left parties’ policy positions using a quantitative cross-country analysis. Second, I provide an overview of the experiences of the four Visegrád Group countries and trace the blue-collar constituencies’ shift away from the ex-Communist left parties to the populist and radical right parties over time, as the left parties became more economically centrist. I then test my argument using constituency-level and individual-level experimental survey data within Hungary. Both methods help establish that the centrist shift of the ex-Communist left parties along the economic policy dimension boosted support for the radical right party. My argument contributes to our understanding of the dynamics of political systems and the rise of the radical right parties in Europe.

Stellar isotropic model in the symmetric teleparallel equivalent of general relativity theory

description: Recently, the theory of symmetric teleparallel equivalent of general relativity (STEGR) has gained much interest in the cosmology and astrophysics community. Within this theory, we discuss the method of deriving a stellar isotropic model. In this respect, we implement the equations of motion of STEGR theory to a spacetime that is symmetric in a spherical manner, resulting in a set of nonlinear differential equations with more unknowns than equations. To solve this issue, we assume a special form of $g_{tt}$, and suppose a null value of the anisotropy to obtain the form of $g_{rr}$. We then investigate the possibility of obtaining an isotropic stellar model consistent with observational data. To test the stability of our model, we apply the adiabatic index and the Tolman-Oppenheimer-Volkoff equation. Furthermore, we examine our model using different observed values of radii and masses of pulsars, showing that all of them fit in a consistent way.

Inferring ECG from PPG for Continuous Cardiac Monitoring Using Lightweight Neural Network

description: This paper presents a computational solution that enables continuous cardiac monitoring through cross-modality inference of electrocardiogram (ECG). While some smartwatches now allow users to obtain a 30-second ECG test by tapping a built-in bio-sensor, these short-term ECG tests often miss intermittent and asymptomatic abnormalities of cardiac functions. It is also infeasible to expect persistently active user participation for long-term continuous cardiac monitoring in order to capture these and other types of cardiac abnormalities. To alleviate the need for continuous user attention and active participation, we design a lightweight neural network that infers ECG from the photoplethysmogram (PPG) signal sensed at the skin surface by a wearable optical sensor. We also develop a diagnosis-oriented training strategy to enable the neural network to capture the pathological features of ECG, aiming to increase the utility of reconstructed ECG signals for screening cardiovascular diseases (CVDs). We also leverage model interpretation to obtain insights from data-driven models, for example, to reveal some associations between CVDs and ECG/PPG and to demonstrate how the neural network copes with motion artifacts in the ambulatory application. The experimental results on three datasets demonstrate the feasibility of inferring ECG from PPG, achieving a high fidelity of ECG reconstruction with only about 40K parameters.
Quadrisecants of knots and links

description: We show that every non-trivial tame knot or link in R^3 has a quadrisecant, i.e. four collinear points. The quadrisecant must be topologically non-trivial in a precise sense. As an application, we show that a nonsingular, algebraic surface in R^3 which is a knotted torus must have degree at least eight.

description: The present research examines student teachers’ perceived learning gains from a game activity in which they were involved. During the game-activity, prospective teachers selected, evaluated and designed educational and non-educational digital games. The game-activity’s goal was student teachers to i) develop skills and understanding over digital games-based learning approach and ii) engage experientially in a game-based learning environment. Students reported learning gains concerning both the content (digital games-based learning) and the method (game-based learning) of the activity they engaged in, while their learning experience was influenced by their prior conceptions and experiences with teaching, learning, technology, and games.

description: Two new compounds, corylifol H (1) and epi-bavacoumestan C (2), together with a new natural product named 8-geranyl daidzein (3), were isolated from the fruits of Cullen corylifolium (L.) Medik. (syn. of Psoralea corylifolia L.) by the targeted separation mode. The structures of these compounds were elucidated on the basis of spectroscopic methods and by comparison with literature properties. The anti-inflammatory effects of the two new compounds were also evaluated by activity assay in vitro. The results showed that compounds 1 and 2 inhibited nitric oxide production in LPS-activated RAW 264.7 macrophages in a dose dependent manner.

description: This study focuses on the use of video as an educational support tool for higher education, especially in the field of Business Administration Studies. The study refers to the contribution of video to the achievement of counselling purposes through the creation and evaluation of scenarios. The results confirm the power and attractiveness of the moving picture in the production of meanings that increase the effectiveness of the counselling and guidance process. Due to this effective integration of video in the counseling process, there is also a shift in existing knowledge and, in part and in the affirmative, a chain of dependencies between initial knowledge/attitude, the effectiveness of video, motivation and new knowledge/attitude. This study promotes the use of video in the field of counselling in Economics and Management and informs both the relative literature and practice.
