description: There is a 40% attrition from all introductory accounting courses based on a study by Hartman, Nix, McFetridge, and Hertz (1982). By identifying students' learning styles and using interactive hypermedia software as an enrichment activity, teachers may be able to reduce attrition from accounting courses. Using interactive hypermedia software as an enrichment activity with a treatment group and computerized application-type problems from the textbook with the control group, 199 students were studied at a community college. Variables such as age, gender, previous computer use, previous accounting education in high school, aptitude, completion of the student orientation course, grade point average, cumulative credits, employment status were also considered. The Learning Style Inventory developed by David Kolb was administered to the students. Using analysis of variance tests, it was determined that students in the treatment group with the accommodator and diverger learning styles scored significantly higher on professor prepared objective accounting achievement tests, in spite of the fact that the interactive software was designed to benefit all learning styles. The best regression models to predict students success on the achievement tests was a model for the treatment group that included aptitude and completion of the student orientation course. If a student was at risk or not employed the lower the test score totals. This model explained 47% of the test score total. The best stepwise model for attrition combined both groups and explained 69% of the probability for attrition. The higher the test scores the lower the attrition. If the student had a high aptitude test score the more likely to leave. If a student was not at risk and was not employed the more likely to leave. The relationship between learning style of accounting students and at risk should be studied further. This may explain their attrition.

description: Physics-informed deep learning has drawn tremendous interest in recent years to solve computational physics problems, whose basic concept is to embed physical laws to constrain/inform neural networks, with the need of less data for training a reliable model. This can be achieved by incorporating the residual of physics equations into the loss function. Through minimizing the loss function, the network could approximate the solution. In this paper, we propose a mixed-variable scheme of physics-informed neural network (PINN) for fluid dynamics and apply it to simulate steady and transient laminar flows at low Reynolds numbers. A parametric study indicates that the mixed-variable scheme can improve the PINN trainability and the solution accuracy. The predicted velocity and pressure fields by the proposed PINN approach are also compared with the reference numerical solutions. Simulation results demonstrate great potential of the proposed PINN for fluid flow simulation with a high accuracy.

Information scrambling in a collision model

description: The information scrambling in many-body systems is closely related to quantum chaotic dynamics, complexity, and gravity. Here we propose a collision model to simulate the information dynamics in an all-optical system. In our model the information is initially localized in the memory and evolves under the combined actions of many-body interactions and dissipation. We find that the information is scrambled if the memory and environmental particles are alternatively squeezed along two directions which are perpendicular to each other. Moreover, the disorder and imperfection of the interaction strength tend to prevent the information flow away to the environment and lead to the information scrambling in the memory. We analyze the spatial distributions of the correlations in the memory. Our proposal is possible to realize with current experimental techniques.

description: We study Cameron-Liebler $k$-sets in the affine geometry, so sets of $k$-spaces in $\text{AG}(n, q)$. This generalizes research on Cameron-Liebler $k$-sets in the projective geometry $\text{PG}(n, q)$. Note that in algebraic combinatorics, Cameron-Liebler $k$-sets of $\text{AG}(n, q)$ correspond to certain equitable bipartitions of the Association scheme of $k$-spaces in $\text{AG}(n, q)$, while in the analysis of Boolean functions, they correspond to Boolean degree $1$ functions of $\text{AG}(n, q)$. We define Cameron-Liebler $k$-sets in $\text{AG}(n, q)$ by intersection properties with $k$-spreads and show the equivalence of several definitions. In particular, we investigate the relationship between Cameron-Liebler $k$-sets in $\text{AG}(n, q)$ and $\text{PG}(n, q)$. As a by-product, we calculate the character table of the association scheme of affine lines. Furthermore, we characterize the smallest examples of Cameron-Liebler $k$-sets. This paper focuses on $\text{AG}(n, q)$ for $n > 3$, while the case for Cameron-Liebler line classes in $\text{AG}(3, q)$ was already treated separately.
An Investigation Into the Makeup of a Successful Mugshare Program : Materials, Tracking, and Organization

description: This investigation explores the UBC Mugshare program and strategies required to execute a successful program. Three primary issues were focused upon: the most sustainable material, what made other mugshare programs successful, and how can the mugs be properly accounted for. A triple bottom line analysis of potential mug materials shows that although plastic is more cost efficient than stainless steel, it has a higher energy footprint, and a number of health concerns attached to it. Accounting for the mug usage requires the ability to track mugs and participants. Digital identification accomplishes this cleanly, the increased data capacity of QR codes or the portability of RFID is unnecessary for this application and a simple barcode can easily accomplish the task. From other mugshare programs it is clear that the two biggest barriers to participation are cost and awareness. The majority of survey respondents indicate that they are unaware these programs exist and how they operate. Additionally, those that were aware tended to shy away from participation if the cost to join is above $5. Based on these findings, it is recommended that the UBC mugshare program proceed with the stainless steel mugs it is currently using. As the program grows and pen and paper accounting becomes infeasible a barcode tracking system should be implemented until such a time that mugshare can link with the UBC card. Finally, two recommendations for implementation are to keep the signup fee close to $5 and to dedicate resources to building awareness of the program.

description: The purpose of this study was to determine if a program/unit evaluation model (Program Unit Review and Resource Reallocation, PURRR) employed by East Coast Community College was successful in its first year; if the method of using key-indicators data was viable for both academic and administrative units; and to determine if similar review procedures were being employed at cohort Maryland Community Colleges. Interviews were conducted with eleven (11) faculty and staff which consisted of six (6) members of the college's PURRR Committee, and five (5) program or unit heads who submitted reviews on their units in the inaugural year of the process. In addition, senior administrators at three cohort Maryland Community Colleges were queried as to methods of assessing productivity at their home institutions. Community colleges across the country are reporting declining enrollments and reduced funding through the states and political subdivisions. College administrators and governing boards are concerned with the possibility of reduced access to a higher education experience as an outcome of increased student tuition. Increased productivity and efficiency in the use of existing resources is of critical interest to the entire public higher education establishment. The study confirmed that the use of a "key-indicator" method of assessing productivity of college programs and administrative units was a viable institutional method to assess efficiency. Faculty and administrators alike were convinced that the process was fair and the data collected would be of vital importance for East Coast Community College in its pursuit of operating efficiency. Among the recommendations advanced by the researcher was the continuation of a formal process of review, conducted on a routine basis by all of the college's academic programs and administrative units. It was also recommended that college faculty and staff on the PURRR committee be chosen from senior membership of each represented affinity group. A final recommendation noted that it appeared possible to "streamline" the process of key-indicator assessments with improved indicator criterion and enhanced computerized databases.

description: Predicting properties of complex, large-scale quantum systems is essential for developing quantum technologies. We present an efficient method for constructing an approximate classical description of a quantum state using very few measurements of the state. This description, called a classical shadow, can be used to predict many different properties: order $\log M$ measurements suffice to accurately predict $M$ different functions of the state with high success probability. The number of measurements is independent of the system size, and saturates information-theoretic lower bounds. Moreover, target properties to predict can be selected after the measurements are completed. We support our theoretical findings with extensive numerical experiments. We apply classical shadows to predict quantum fidelities, entanglement entropies, two-point correlation functions, expectation values of local observables, and the energy variance of many-body local Hamiltonians. The numerical results highlight the advantages of classical shadows relative to previously known methods.

description: Animal hosts have evolved intricate associations with microbial symbionts, where both depend on each other for particular functions. In many cases, these associations lead to phylosymbiosis, where phylogenetically related species harbour compositionally more similar microbiomes than distantly related species. However, evidence for phylosymbiosis is either weak or lacking in gut microbiomes of flying vertebrates, particularly in birds. To shed more light on this phenomenon, we compared cloacal microbiomes of 37 tropical passerine bird species from New Guinea using 16S rRNA bacterial gene sequencing. We show a lack of phylosymbiosis and document highly variable microbiomes. Furthermore, we find that gut bacterial community compositions are species-specific and tend to be shaped by host diet but not sampling locality, potentially driven by the similarities in habitats used by individual species. We further show that flight-associated gut modifications, coupled with individual dietary differences, shape gut microbiome structure and variation, contributing to the lack of phylosymbiosis. These patterns indicate that the stability of symbiosis may depend on microbial functional diversity rather than taxonomic composition. Furthermore, the more variable and fluid host–microbe associations suggest probable disparities in the potential for coevolution between bird host species and microbial symbionts.

description: There is now significant historical data available on decision making in organizations, consisting of the decision problem, what decisions were made, and how desirable the outcomes were. Using this data, it is possible to learn a surrogate model, and with that model, evolve a decision strategy that optimizes the outcomes. This paper introduces a general such approach, called Evolutionary Surrogate-Assisted Prescription, or ESP. The surrogate is, for example, a random forest or a neural network trained with gradient descent, and the strategy is a neural network that is evolved to maximize the predictions of the surrogate model. ESP is further extended in this paper to sequential decision-making tasks, which makes it possible to evaluate the framework in reinforcement learning (RL) benchmarks. Because the majority of evaluations are done on the surrogate, ESP is more sample efficient, has lower variance, and lower regret than standard RL approaches. Surprisingly, its solutions are also better because both the surrogate and the strategy network regularize the decision-making behavior. ESP thus forms a promising foundation to decision optimization in real-world problems.
An anthropological discourse analysis of a Deaf Namibian refugee's life story

description: This dissertation demonstrates how discourse analysis provides access to the ways in which a Deaf Namibian uses available linguistic and cultural resources to construct an identity via narrative. Life stories provide a way to analyze how individuals actively and jointly interpret and negotiate their world view, as narrating a life story involves selecting and interpreting culturally significant experiences. The data were derived from videotaped interactions of a Deaf Owambo relating his life story in Namibian Sign Language to a group of Deaf Namibian peers. The structural analysis focuses on repetition of temporal lexical markers and spatial features including eyegaze movements, headturns and body shifts. Both temporal and spatial linguistic repetition work together to structure the life story in terms of hierarchically organized units, which the researcher terms in ascending order: epitopes, contratopes, chronotopes and hemitopes. These units are inter-textually related and function to give the subject's narrative identity both structure and meaning. The anthropological interpretation involved building a theoretical framework for life story analysis. This framework demonstrates that the details of the structural analysis are critical to a post-modern deconstruction of the text in terms of narrative identity. However the structural analysis masks the unfinalizable fluid spatial elements of the text which constitute the narrator's construction of identity. The anthropological interpretation of the textual construction of socio-cultural identity hinges on the interaction between the narrative structure of the text, its thematic structure and the poetic use of spatial stylistic devices. The essence of the narrator's Deaf Namibian identity is contained in the dialogic inter-textual relations.

description: FRB 180916.J0158+65 has been found to repeatedly emit fast radio bursts with the period in roughly 16 days. We propose that such periodicity comes from orbit-induced, spin precession of the emitter, which is possibly a neutron star. Depending on the mass of the companion, the binary period ranges from several hundred to thousands of seconds. Such tight binaries have a relatively short lifetime, which does not likely come from the gravitational decay of a wide binary. We comment on the relation to GW190425 and the possibility in LISA and LIGO detections.

I proceed with the argumentation that torsion is required for the description of intrinsic spin. Moreover I argue that the duality between curvature and torsion is analogous to the duality between electricity and magnetism. I conclude this article by pointing out that the aligned rotation axes of the galaxies of the Perseus-Pisces supercluster may be interpreted as a topological defect generated by torsion.

Econometric estimation of portfolio balance and monetary models of exchange rate determination: The case of Canada
Creators: name: Paralkar, Rajashree Shree
Publisher: name: American University
Year: 2023

description: The primary purpose of this dissertation is to present, solve, and estimate a portfolio balance model and its extensions for the Canadian/U.S. exchange rate, and evaluate the out-of-sample forecasting performance of each of these models by comparing it to that of the random walk model. Current literature reveals the structural models of exchange rate determination to be deficient in explaining exchange rate movements. In particular, we find the empirical validity of monetary models to be worth examining, given the abundance of literature pointing to their demise. Our purpose is to show that the pessimism with reference to these models is unfounded, at least for the Canadian/U.S. exchange rate. We apply the most recently developed non-stationarity and cointegration techniques to examine the time-series properties of the variables. Each of these models is then appropriately estimated given these underlying time-series properties. Another objective of this dissertation is to test the cross-equation restrictions imposed by the rational expectations solution, This involves a joint test of the structural model and the rational expectations hypothesis,; Finally, the out-of-sample prediction properties of these structural models are analyzed. We will provide evidence that at least one of our structural models is capable of out-performing the simple random walk model. We estimate our models for Canada using quarterly data for the period 1971 to 1992, Based on the likelihood ratio test, we cannot reject the joint hypothesis of any of our structural models and the rational expectations assumption. We also find evidence that the structural exchange rate models are quite capable of out-performing the simple random walk model, at least for the Canadian/U.S. exchange rate. We find our results to be interesting because previous researchers in this field have provided evidence against structural exchange rate models. By modifying a few assumptions in the traditional structural models, we succeed in showing that the structural models are still very much alive.

description: In this paper, we present results at next-to-leading order (NLO) QCD for photon pair production in association with two jets via vector boson scattering within the Standard Model (SM), and also in an effective field theory framework with anomalous gauge coupling effects via bosonic dimension-6 and 8 operators. We observe that, compared to other processes in the class of two electroweak (EW) vector boson production in association with two jets, more exclusive cuts are needed in order to suppress the SM QCD-induced background channel. As expected, the NLO QCD corrections reduce the scale uncertainties considerably. Using a well-motivated dynamical scale choice, we find moderate $K$-factors for the EW-induced process while the QCD-induced channel receives much larger corrections. Furthermore, we observe that applying a cut of $Δϕ_{j_2 γ_1}^{\text{cut}} < 2.5$ for the second hardest jet and the hardest photon helps to increase the signal significance and reduces the impact of higher-order QCD corrections.

description: A key goal of conservation is to protect biodiversity by supporting the long-term persistence of viable, natural populations of wild species. Conservation practice has long been guided by genetic, ecological and demographic indicators of risk. Emerging evidence of animal culture across diverse taxa and its role as a driver of evolutionary diversification, population structure and demographic processes may be essential for augmenting these conventional conservation approaches and decision-making. The animal culture was the focus of a ground-breaking resolution under the Convention on the Conservation of Migratory Species of Wild Animals (CMS), an international treaty operating under the UN Environment Programme. Here, we synthesize existing evidence to demonstrate how social learning and animal culture interact with processes important to conservation management. Specifically, we explore how social learning might influence population viability, be an important resource in response to anthropogenic change and provide examples of how it can result in phenotypically distinct units with different, socially learnt behavioural strategies. While identifying culture and social learning can be challenging, indirect identification and parsimonious inferences may be informative. Finally, we identify relevant methodologies and provide a framework for viewing behavioural data through a cultural lens which might provide new insights for conservation management.

description: The primary purpose of this dissertation is to present, solve, and estimate a portfolio balance model and its extensions for the Canadian/U.S. exchange rate, and evaluate the out-of-sample forecasting performance of each of these models by comparing it to that of the random walk model. Current literature reveals the structural models of exchange rate determination to be deficient in explaining exchange rate movements. In particular, we find the empirical validity of monetary models to be worth examining, given the abundance of literature pointing to their demise. Our purpose is to show that the pessimism with reference to these models is unfounded, at least for the Canadian/U.S. exchange rate. We apply the most recently developed non-stationarity and cointegration techniques to examine the time-series properties of the variables. Each of these models is then appropriately estimated given these underlying time-series properties. Another objective of this dissertation is to test the cross-equation restrictions imposed by the rational expectations solution, This involves a joint test of the structural model and the rational expectations hypothesis,; Finally, the out-of-sample prediction properties of these structural models are analyzed. We will provide evidence that at least one of our structural models is capable of out-performing the simple random walk model. We estimate our models for Canada using quarterly data for the period 1971 to 1992, Based on the likelihood ratio test, we cannot reject the joint hypothesis of any of our structural models and the rational expectations assumption. We also find evidence that the structural exchange rate models are quite capable of out-performing the simple random walk model, at least for the Canadian/U.S. exchange rate.

description: The potential for probing extra neutral gauge boson mediators ($Z^\prime$) from low-energy measurements is comprehensively explored. Our study mainly focuses on $Z^\prime$ mediators present in string-inspired $E_6$ models and left-right symmetry. We estimate the sensitivities of coherent-elastic neutrino-nucleus scattering (CE$ν$NS) and neutrino-electron scattering experiments. Our results indicate that such low-energy high-intensity measurements can provide a valuable probe, complementary to high-energy collider searches and electroweak precision measurements.

How does one know oneself and others? An empirical study of social actions involving one focal person with a disability and his consociates

description: This study investigates how a particular group of Americans create themselves as persons and selves in daily practice. The focus is on the constituting actions and subjects' own interpretations. To access actual lived experiences I chose auto-ethnographic and grounded theory methods. The universe of inquiry was determined by one focal person, an American middle class male, and 28 consociates who were witnesses and co-creators of personhood at different times, places, and occasions. The data obtained consisted of multifaceted, polyvocal descriptions and interpretations of the constituting actions, ingredients, and creators of personhood and selfhood. Analysis included participants' exegeses and critical assessment of their own practices. I used processual concepts to analyze the socially transforming and positioning dynamics of quotidian practices. The participants recognized themselves to be permeable persons who transmit to, exchange with, and absorb in various ways from others. With their social actions they continually positioned and defined themselves together which led me to understand the equivalence of social processes and social structure. Personal change was experienced across space, time, and situations but balanced with continuity-creating stabilizing bonds, repetitive practices, and ascriptions of perduring capacities and essences. "Private selves" and "public persons" were interchangeable and conjointly created to protect continuity of togetherness. Selfhood emerged as totally social actions which involved body, emotions, cognitions, religious sentiments, and social others. When feeling close, creating bonds of solidarity and trust, and making love, selfhood became sociocentric, interpenetrating, and dissolved in union with others. By closing out others, participants stabilized selfhood, created otherness, and rendered others incomplete or disabled. I related micro-processes with long-term and large-scale processes based on participants involvements in continuing social worlds and my own evaluation of explanatory models. Selfhood is experienced personhood, socially created, and continuously emergent. The bounded, individualistic "self" is a hypercognized synthesis of one among several social processes. A focus on "the individual" person yields an incomplete understanding of lived personhood. Opposing individual to society is unwarranted since personhood and quality of sociality are created with the same social actions. Authorship of incompleteness and disablements lies with persons and their actions.

description: A new exactly solvable relativistic periodic potential is obtained by the periodic extension of a well-known transparent scalar potential. It is found that the energy band edges are determined by a transcendental equation which is very similar to the corresponding equation for the Dirac Kronig-Penney model. The solutions of the Dirac equation are expressed in terms of elementary functions.

description: The Allen-Cahn equation is a fundamental model for phase transitions, offering critical insights into the dynamics of interface evolution in various physical systems. This paper investigates the stability and robustness of frequently utilized time-discretization numerical schemes for solving the Allen-Cahn equation, with focuses on the Backward Euler, Crank-Nicolson (CN), convex splitting of modified CN, and Diagonally Implicit Runge-Kutta (DIRK) methods. Our stability analysis reveals that the Convex Splitting of the Modified CN scheme exhibits unconditional stability, allowing greater flexibility in time step selection, while the other schemes are conditionally stable. Additionally, our robustness analysis highlights that the Backward Euler method converges to correct physical solutions regardless of initial conditions. In contrast, the other methods studied in this work show sensitivity to initial conditions and may converge to incorrect physical solutions if the initial conditions are not carefully chosen. This study introduces a comprehensive approach to assessing stability and robustness in numerical methods for solving the Allen-Cahn equation, providing a new perspective for evaluating numerical techniques for general nonlinear differential equations.
