本研究は、6つのアジア諸言語―日本語、インドネシア語、韓国語、ベトナム語、タガログ語、中国語―の断り表現を比較し、断り表現における意味公式の出現順序は、言語の構造(主要部先頭・最終)と関係があることを明らかにすることを目的とする。主要部先頭言語は、「断り」を他の意味公式より先に述べる傾向があり、一方、主要部最終言語は、他の意味公式を先に言ってから、「断り」を述べるという結果が見られた。 / This study investigated refusal expressions in six Asian languages—Japanese, Indonesian, Korean, Vietnamese, Filipino, and Chinese—. The purpose of this study was to examine whether there is a relationship between language category (head-initial/final language) and the occurrence of semantic formula function groups (SFFGs) in refusal expressions. The result of analyses on refusal expressions of the six languages showed that head-initial languages have a strong tendency to use "Refusal" before another semantic formula, and head-final languages have a tendency to use "Refusal" after other SFFGs. / 博士(文化情報学) / Doctor of Culture and Information Science / 同志社大学 / Doshisha University

Special education has evolved into a dominant area of education since first brought to the forefront. The reauthorization of the Education for All Handicapped Children Act to the Individuals with Disabilities Education Act updated and addressed many issues, including parental issues. Initially parents had to fight to be heard when addressing the needs and concerns of their child. Now parents are considered a crucial part of the special education process. The purpose of this qualitative study was to explore the thoughts and experiences of parents of children with disabilities related to the initial special education placement and the ongoing communication between parents and school professionals. Data were collected through interviews with 20 parents of children with disabilities in their initial years of service from a rural county in East Tennessee. Interviews were conducted mainly in parents' homes. Data were identified using interpretative analysis. Descriptive information about participants and their initial reactions were recorded in a journal. From the findings the researcher concluded parents whose children were identified from birth to school age knew much more information about their child's disabilities; however, parents with children identified with disabilities after entering school needed a great deal more information than was provided, such as specifics on the child's disability and the process of special education implementation of the IEP. Most parents who addressed concerns to school professionals had positive outcomes, although there were communication breakdowns and conflicts before resolutions were reached. The majority of parents stated they were as actively involved in their child's school experience as they were initially; however, a few parents stated they were more involved because of conflict situations. Parents agreed that communication had increased with school professionals but more frequent and clearer communication was needed.

We show our work to refine the process of evolutions in general relativistic magnetohydrodynamics. We investigate several areas in order to improve the overall accuracy of our results. We test several versions of conversion methodologies between different sets of variables. We compare both single equation and two equations solvers to do the conversion. We find no significant improvement for multiple equation conversion solvers when compared to single equation solvers. We also investigate the construction of initial data and the conversion of coordinate systems between initial data code and evolution code. In addition to the conversion work, we have improved some methodologies to ensure data integrity when moving data from the initial data code to the evolution code. Additionally we add into the system of MHD equations a new field to help control the no monopole constraint. We perform a characteristic decomposition of the system of equations in order to derive the associated boundary condition for this new field. Finally, we implement a WENO (weighted non-oscillatory) system. This is done so we can evolve and track shocks that are generated during an evolution of our GRMHD equations.

Context The number of Initial Public Offerings on the Swedish market has increasedrapidly over the last decade, reporting over 100 IPOs only in 2021. Although theincrease has been extraordinary, the majority of the IPO performance researchhas been conducted on larger markets such as the US, Germany, and China. Thiscreates a gap in the research regarding the performance of IPOs on the fastgrowing Swedish stock market.  Purpose The purpose of this thesis is to fill the identified research gap and examine howthe Swedish IPOs perform in relation to established firms listed on the OMXSSmall Cap. Findings on long-term over-or underperformance would lay afoundation for potential investment strategies as well as show signs ofinformation asymmetry and mispricing. To further extend the use of ourfindings, firm-specific factors will be tested in a regression model to find ifspecific firm characteristics have a positive or negative impact on the long-termperformance of the IPOs.  Questions at issue 1. Does the Swedish Initial Public Offerings over/underperform comparedto the OMXS Small Cap in the long run? 2. Which firm-specific factors affect the long-term performance of an IPO? Methodology To find if the IPOs over-or underperform the OMXS Small Cap index, the Buyand Hold Abnormal Returns over 24 and 36 months are calculated with theOMXS Small Cap as a benchmark index. Further, a regression analysis with 15explanatory variables is performed with the received BHAR results as thedependent variable to find if there are any significant relationships between thefirm-specific variables measured before the IPO and the long-term performance.  Results The Buy and Hold Abnormal Returns presented a positive abnormal return forboth periods measured, with a significant overperformance of 9,91% over the36-month period, and 21,14% for the 24-month period. Further, the regressionanalysis showed a positive relationship between firm performance and firm sizeand Return On Equity, indicating that a high ROE, as well as a larger firm sizeat the date of the listing, increases the chances of higher long-term returns.

The aim of the project was to investigate a green and sustainable replacement for boric acid in polyvinyl alcohol (PVA) adhesives for solid paperboard production. Boric acid acts as a cross-linker and tackifier in the adhesive but is classified as a harmful substance. Microfibrillated cellulose (MFC) was therefore investigated as a possible replacement for boric acid since it is produced from renewable and sustainable resources. In addition, it has hydroxyl groups available for interaction with the PVA, can be used to modulate the viscosity and can function under a variety of pH-values.  For the industrial process, there are three basic characteristics which must be met by the newly developed adhesive, which have to be the same as for the boric acid-containing reference. These three are the viscosity, the pH-value, and the dry content. Furthermore, it is important that the initial wet tack and the final adhesive strength are at least as high as the reference’s.  In this context, eight types of samples were investigated in total. Two were references, one prepared on industrial and the second on a laboratory scale according to a current industrial recipe. In the other six samples, the boric acid from the recipe was replaced by three different weight percentages of MFC of two different industrial grades. Both the dry content and the pH-value were not noticeably influenced by the addition of MFC. The viscosity however increased drastically with the increasing amount of MFC. The addition of MFC was enough to reach the three basic characteristics. In addition it was observed positive effects on a couple of other parameters that is beneficial for the glue.   A test method for evaluating the initial wet tack of the adhesive was developed. It was shown, that the tack of the adhesive containing MFC is 40 % lower than the one of the reference material. Therefore, five additives were tested in the formulation, in combination with MFC. The most promising result led to a comparable initial tack and final strength as the reference.

A recent method for solving singular perturbation problems is examined. It is designed for the applied mathematician or engineer who needs a convenient, useful tool that requires little preparation and can be readily implemented using little more than an industry-standard software package for spreadsheets. In this paper, we shall examine singularly perturbed two point boundary value problems with the boundary layer at one end point. An initial-value technique is used for its solution by replacing the problem with an asymptotically equivalent first order problem, which is, in turn, solved as an initial value problem by using cubic splines. Numerical examples are provided to show that the method presented provides a fine approximation of the exact solution. The first chapter provides some background material to the cubic spline and boundary value problems. The works of several authors and a comparison of different solution methods are also discussed. Finally, some background into the specific singularly perturbed boundary value problems is introduced. The second chapter contains calculations and derivations necessary for the cubic spline and the initial value technique which are used in the solutions to the boundary value problems. The third chapter contains some worked numerical examples and the numerical data obtained along with most of the tables and figures that describe the solutions. The thesis concludes with some reflections on the results obtained and some discussion of the error bounds on the calculated approximations to the exact solutions for the numeric examples discussed

The following thesis regards the use of small aperture telescopes for space domain awareness efforts. The rapidly populating space domain was motivation for the development of a new operation scheme to conduct space domain awareness feasibility studies using small telescopes. Two 14-inch Schmidt-Cassegrain Telescopes at the California Polytechnic State University and the Air Force Research Lab in Kirtland AFB, NM, in conjunction with a dedicated CCD camera and a commercial DSLR camera, were utilized to conduct optical observations on satellites in Earth orbit. Satellites were imaged during August 2019, and from January 2020 to March 2020, resulting in the collection of 77 valid images of 16 unique satellites. These images were used to obtain celestial spherical coordinates, which were used in Gauss and Double-R angles-only initial orbit determination methods. Initial orbit determination methods successfully produced valid results, reaffirming the feasibility of using small aperture telescopes for such methods. These orbit determinations were used to propagate orbit states forward in time to determine the feasibility of future imaging of the targets with the same apparatus. Propagation results demonstrated that initial orbit determinations rapidly decayed in accuracy over distant times and are most accurate for immediate satellite passes. In addition, an attempt to combine multiple initial orbit determinations using Lambert’s problem solutions was made. Combination of these multiple initial orbit determinations resulted in either no orbit state accuracy improvement compared to individual initial orbit determinations, or a decrease in accuracy compared to these methods. Ultimately, efforts demonstrated that small telescope usage is feasible for orbit determination operations, however there may be a need for hardware and operational revisions to improve the ability of the apparatus.

In this dissertation, I study a nonlinear partial differential equation, the complex Ginzburg-Landau (CGL) equation. I first employed the perturbative field-theoretic renormalization group method to investigate the critical dynamics near the continuous non-equilibrium transition limit in this equation with additive noise. Due to the fact that time translation invariance is broken following a critical quench from a random initial configuration, an independent ``initial-slip'' exponent emerges to describe the crossover temporal window between microscopic time scales and the asymptotic long-time regime. My analytic work shows that to first order in a dimensional expansion with respect to the upper critical dimension, the extracted initial-slip exponent in the complex Ginzburg-Landau equation is identical to that of the equilibrium model A. Subsequently, I studied transient behavior in the CGL through numerical calculations. I developed my own code to numerically solve this partial differential equation on a two-dimensional square lattice with periodic boundary conditions, subject to random initial configurations. Aging phenomena are demonstrated in systems with either focusing and defocusing spiral waves, and the related aging exponents, as well as the auto-correlation exponents, are numerically determined. I also investigated nucleation processes when the system is transiting from a turbulent state to the ``frozen'' state. An extracted finite dimensionless barrier in the deep-quenched case and the exponentially decaying distribution of the nucleation times in the near-transition limit are both suggestive that the dynamical transition observed here is discontinuous.

I study this equation using both analytical and numerical methods. First, I employed the field theory approach to extract the critical initial-slip exponent, which emerges due to the breaking of time translation symmetry and describes the intermediate temporal window between microscopic time scales and the asymptotic long-time regime. I also numerically solved this equation on a two-dimensional square lattice. I studied the scaling behavior in non-equilibrium relaxation processes in situations where defects are interactive but not subject to strong fluctuations. I observed nucleation processes when the system under goes a transition from a strongly fluctuating disordered state to the relatively stable “frozen” state where its dynamics cease. I extracted a finite dimensionless barrier for systems that are quenched deep into the frozen state regime. An exponentially decaying long tail in the nucleation time distribution is found, which suggests a discontinuous transition. This research is supported by the U. S.
