title: Investigation of the Biosynthetic Process of Indigoidine
Creators: name: Chen, Yi
Publisher: name: Utah State University
Year: 2019

description: Indigoidine is a natural blue dye with antioxidant and antimicrobial activities. It has also been used as an indicator for gene expression based on its distinctive blue color. Similar to the industry blue dye indigo, indigoidine has a promising potential to be applied in industry as a blue dye. However, the indigoidine production level in the original microorganisms was very low. Heterologous expression of the responsible synthetase gene in Escherichia coli can facilitate the fast and large-scale production of indigoidine. Also, a good understating of the working mechanism of the synthetase is favorable for the industrial application.
In our previous study, a putative indigoidine synthetase gene (Sc-indC) has been heterologously expressed in E. coli, and 20 g/L of indigoidine was produced under optimized culture conditions. To further improve the production, we intended to explore the indigoidine biosynthetic process by studying the working mechanism of two indigoidine synthetases BpsA and Sc-IndC from two different bacteria.
Both BpsA and Sc-IndC were predicted to have similar domain architecture that consists of an adenylation domain (A) with an embedded oxidation (Ox) domain, thiolation (T) domain, and thioesterase (TE) domain, except that Sc-IndC has an additional C-terminal. To explore the enzymatic mechanism, I dissected the gene between domains to get A-Ox-T/TE and A-Ox/T-TE, and co-expressed the dissected fragments to find out whether they can work in the combination of pieces as the intact enzymes do. On the other hand, I separately expressed the domains in E. coli BAP1 and purified the resulting proteins, and tested the in vitro activities on precursors individually or in different combinations. My results showed that the intact enzymes can convert glutamine, glutamine-SNAC and pyor-Gln to indigoidine in the presence of ATP. However, none of the dissected enzymes showed the ability to form the blue dye in vitro or in vivo.

title: Centerville City Parks Master Plan
Creators: name: Stead, Paul
Publisher: name: Utah State University
Year: 2019

description: This Plan B Thesis is a comprehensive update to Centerville City’s Parks Master Plan. The document seeks to provide stability and continuity to Centerville’s open space infrastructure. Since the last update in 1993, the Parks Master Plan has been without regular updates to reflect the community’s needs and values. As a result, the Plan has largely been ignored and Centerville has lacked a unified vision regarding parks planning. The objective of this thesis project is to help promote a unique recreational identity that assists the community in positively differentiating itself from other communities on the Wasatch Front.
The Inventory and Analysis sections outline existing site conditions for all Centerville Parks, document areas of concern and measure Centerville against National Park Standards. A large portion of analysis is the development and administration of a community survey. This survey ascertained the needs and wants of the residents to inform the Master Plan update. The recommendations that resulted from the community feedback correlated with input from the Parks Director, the Parks Committee and the City Council, resulting in a plan that provides Centerville City with direction for future recreation, allows them to move forward with a unified vision, helps form connections between the parks and trails throughout the city and embraces adjoining land and communities. This Parks Master Plan emphasizes Centerville’s unique identity, healthy lifestyles, and helps them stand out among communities on the Wasatch Front.
title: Called to Serve: Understanding the Role of the Woman’s Mission Decision Narrative in Latter-Day Saint Culture and Belief
Creators: name: Ross, Rachel
Publisher: name: Utah State University
Year: 2019

description: In my thesis I explore the role of mission decision narratives of women in The Church of Jesus Christ of Latter-day Saints. Before 2012, women could not serve missions until age 21. Once the minimum age was changed to 19 in October of 2012, many more women were able to serve on mission as the opportunity was less likely to disrupt their education or romantic relationships. In The Church of Jesus Christ of Latter-day Saints, missions are seen as a priesthood duty for men but a matter of choice for women. This ability to choose and the narrative that follows plays an important role for women and the church overall. The question “How did you decide to serve a mission?” is a relatively frequently asked question of Latter-day Saint women and the story that follows is indicative of the view women have of themselves and their relationship with God. Many women struggle greatly looking for the answer and this very struggle can serve as the genesis of their tangible identity in the church and can come to define their spiritual identity.
My thesis discusses the scholarly work that relates to personal revelation narratives and Latter-day Saint folklore in general. I highlight Tom Mould’s pivotal work and discuss the space in which my research fits and creates new understanding of Latter-day Saint women and culture. I then present my research in which I interviewed seven women who served missions after October 2012. I analyzed themes and ideas expressed in these interviews, seeking out common patterns and seeming anomalies. Each woman that I interviewed was fairly different in personality and temperament, yet there were common threads between all of them. Each struggled to make the decision, many received timely and oracle-like advice from family members or friends.
Ultimately, I have found that these stories are an important way to acknowledge a space in which women exist in the church and in which their identities are created and celebrated. It is vital to understand that the decision to go on a mission is not just a momentary experience but a reflection of what a religious community cares about and how religious beliefs are put into action by women who believe them.
title: Shall I Sing You a Ghost Story: The Nature and Purpose of Ghost Songs in Maritime Communities of Northern New England and Atlantic Canada
Creators: name: Blake, Richard A.
Publisher: name: Utah State University
Year: 2019

description: This paper will be discussing the nature of maritime ghost stories put forth in musical narrative. There are two questions that I will be endeavoring to answer. 1) What kinds of changes can occur to a ghost story when it is put into a song and 2) How would the understanding of a folksong’s story change when it crosses boundaries from one place to another? More specifically it will discuss those changes when crossing provincial or national boundaries. The investigation into these questions will involve the use of several written and audio sources. The written sources include titles like the books Maritime Folksongs by Helen Creighton and The Folklore of Maine by Horace Beck. These books each include a different version of the song. Beck’s book also includes a description of the historical event of which the song is based.
To get a true grasp of language and meaning with tone it is essential to hear how one sings a song in the present day along with any older recordings of the same song. The audio sources will be online sources off of sites like Youtube and Memorial University of Newfoundland’s Folklore Archives. The song is sung in different tones, some at faster paces than others. Most of the versions are accompanied by music, but one is sung acapella. Of the audio recordings the acapella version will receive extra scrutiny as it would be more in sync with how the song originally sounded. Songs that were designated in what is called the fo’c’sle tradition on a ship had no accompanying music.
An important thing that will be noted is how superstition helped to determine a sailor’s actions and rituals at sea. Many rituals and taboos exist to those at sea in order to ward off evil and bad luck. In discussing the song I will also analyze how these beliefs affected maritime music. Then endeavor to find any hidden meanings within the language that might differ from the layman’s interpretation of what the sailor’s song is telling us.
title: Potential Weather Data Anomolies within the USDA's Pasture Rangeland and Forage Insurance Program
Creators: name: Van Orden, Chad Steven
Publisher: name: Utah State University
Year: 2019

description: The purpose of this study is to delve into the functionality of the PRF insurance program. The primary goal is to uncover any underlying anomalies which may inadvertently skew data within the program. Because the USDA uses NOAA’s weather stations regardless of location or timing of activation, it is consequential that the collected precipitation data may be inconsistent across both time and space. This phenomenon could have substantial and significant effects on the RMA’s PRF insurance program, resulting in producers being compensated inaccurately for their insurance claims.

description: Let $\H^{n+1}$ denote the $n + 1$-dimensional (real) hyperbolic space. Let $\s^{n}$ denote the conformal boundary of the hyperbolic space. The group of conformal diffeomorphisms of $\s^n$ is denoted by $M (n)$. Let $M_o (n)$ be its identity component which consists of all orientation-preserving elements in $M (n)$. The conjugacy classification of isometries in $M_o (n)$ depends on the conjugacy of $T$ and $T^{-1}$ in $M_o (n)$. For an element $T$ in $M (n)$, $T$ and $T^{-1}$ are conjugate in $M (n)$, but they may not be conjugate in $M_o (n)$. In the literature, $T$ is called real if $T$ is conjugate in $M_o (n)$ to $T^{-1}$. In this paper we classify real elements in $M_o (n)$. Let $T$ be an element in $M_o(n)$. Corresponding to $T$ there is an associated element $T_o$ in $SO(n+1)$. If the complex conjugate eigenvalues of $T_o$ are given by $\{e^{iθ_j}, e^{-iθ_j}\}$, $0 < θ_j \leq π$, $j=1,...,k$, then $\{θ_1,...,θ_k\}$ are called the \emph{rotation angles} of $T$. If the rotation angles of $T$ are distinct from each-other, then $T$ is called a \emph{regular} element. After classifying the real elements in $M_o (n)$ we have parametrized the conjugacy classes of regular elements in $M_o (n)$. In the parametrization, when $T$ is not conjugate to $T^{-1}$, we have enlarged the group and have considered the conjugacy class of $T$ in $M (n)$. We prove that each such conjugacy class can be induced with a fibration structure.

description: Genome-scale datasets are resolving challenging nodes across the tree of life. These datasets, however, characterized by inherent heterogeneity, often push traditional phylogenetic reconstruction methods to their limits. By integrating multiple phylogenomic approaches, we can identify the causes of topological discordance within genomic partitions while accounting for various sources of heterogeneity and systematic errors. Here we conduct the first in-depth analysis of discordance for the reef family Pomacanthidae (marine angelfishes) using target enrichment data of ~1,000 ultraconserved elements from 45 pomacanthid species. Our combined phylogenomic approach resolved the systematics of the family at the base of the pomacanthid tree. Despite this resolution, our analyses also highlight discordance in ancestral nodes associated with the paraphyletic Centropyge genus and monotypic Pygoplites lineage, and the impact of incomplete lineage sorting in the evolutionary history of pomacanthids. Species network searches and model selection supported a reticulated evolutionary history, suggesting three ancient gene flow events between ghost (or unsampled) lineages at the root of the Pomacanthidae tree and ancestors of Genicanthus, Centropyge, Chaetodontoplus, and Pomacanthus lineages. This study advances our understanding of diagnosing topological discordance in genome-scale phylogenies and provide an analytical pathway for limiting systematic errors. In the process of diagnosing discordance, we identify key evolutionary processes involved in the complex evolution of marine angelfishes. While often inconvenient in phylogenetic analyses, patterns of discordance can shed light on underlying biological and evolutionary processes that shape the evolution of biodiversity.

title: Incorporating Natural Play Spaces into Elementary Playgrounds for Child Developmental Benefits
Creators: name: Wright, Ariel L.
Publisher: name: Utah State University
Year: 2019

description: Play environments are crucial to providing developmental opportunities for children and natural playgrounds provide a developmentally rich play environment. This study compared elementary school playgrounds and nature explore classrooms to determine what natural play spaces can be implemented into an elementary school playground for developmental benefits. The playgrounds were evaluated on safety, ADA requirements and what developmental affordances are encouraged through different play components. A Nature Playground Play Spaces List and handouts were developed, and a playground design exploration was conducted as an example for how the play spaces list can be used and to show what benefits can be seen from incorporating the play spaces.
The study suggests that there are developmental benefits in incorporating natural play spaces into an elementary school playground and through intentional design and consideration these spaces can provide greater developmental opportunities for children.
Nutritional value of grain legumes

description: Systems to evaluate protein feeds for ruminants use solubility measurements as proxies for protein degradation in the rumen. Soluble protein (nitrogen, N) is assumed to be rapidly degraded in the rumen and so likely to be used inefficiently. This practice note demonstrates that this assumption is not appropriate for pea, faba bean and lupin and has led to an under-valuing of protein from these feeds. There are large discrepancies between solubility methods, as well as the lack of relationship to measured protein degradability. This insight helps farmers and the feed industry better evaluate the protein value of these alternative grain legumes. Current feed evaluation systems, based on soluble nitrogen measurements, tend to undervalue pea, faba bean and lupin in comparison with other protein sources for ruminants. New work on protein feed evaluation systems is needed since the current systems constrain the use of these grain legumes in ruminant feeding. This information provides a foundation to industry placing a higher financial value on protein in pea, faba bean and lupin.

description: The Mid-Infrared Instrument (MIRI) on-board JWST will provide imaging, coronagraphy, low-resolution spectroscopy and medium-resolution spectroscopy at unprecedented sensitivity levels in the mid-infrared wavelength range. The Medium-Resolution Spectrometer (MRS) of MIRI is an integral field spectrograph that provides diffraction-limited spectroscopy between 4.9 and 28.3 um, within a FOV varying from 13 to 56" square. From ground testing, we calculate the physical parameters essential to general observers and calibrating the wavelength solution and resolving power of the MRS is critical for maximising the scientific performance of the instrument. We have used ground-based observations of discrete spectral features in combination with Fabry-Perot etalon spectra to characterize the wavelength solution and spectral resolving power of the MRS. We present the methodology used to derive the MRS spectral characterisation, which includes the precise wavelength coverage of each MRS sub-band, computation of the resolving power as a function of wavelength, and measuring slice-dependent spectral distortions. The resolving power varies from R3500 in channel 1 to R1500 in channel 4. Based on the ground test data, the wavelength calibration accuracy is estimated to be below one tenth of a pixel, with small systematic shifts due to the target position within a slice for unresolved sources, that have a maximum amplitude of about 0.25 spectral resolution elements. Based on ground test data, the MRS complies with the spectral requirements for both the R and wavelength accuracy for which it was designed. We also present the commissioning strategies and targets that will be followed to update the spectral characterisation of the MRS.

description: It is usually admitted that the inverse Faraday effect (IFE) originates from the spin angular momentum (SAM) of light. In this paper, we evidence that part of the IFE in a metal is induced by the orbital angular momentum (OAM) of light. On the basis of a hydrodynamic model of the conduction electron gas, we describe the dependence of the IFE on the spin and orbital angular momenta as well as spin-orbit interaction in a non-paraxial light beam. We also numerically quantify the relative contributions of the SAM and OAM of light to the IFE in a thin gold film illuminated by different focused beams carrying SAM and/or OAM. The OAM of light provides a new degree of freedom in the control of the IFE and resulting optomagnetic field, thus potentially impacting various research fields including all-optical magnetization switching and spin-wave excitation.

We show general theorems and their implications and apply the approach to the particle confinement in fields of rotational symmetry. Misconceptions of extensive use of the quasienergy and generalized thermodynamic potential theories are exposed.

description: We use the angular Two Point Correlation Function (TPCF) to investigate the hierarchical distribution of young star clusters in 12 local (3--18 Mpc) star-forming galaxies using star cluster catalogues obtained with the \textit{Hubble Space Telescope} (\textit{HST}) as part of the Treasury Program LEGUS (Legacy ExtraGalactic UV Survey). The sample spans a range of different morphological types, allowing us to infer how the physical properties of the galaxy affect the spatial distribution of the clusters. We also prepare a range of physically motivated toy models to compare with and interpret the observed features in the TPCFs. We find that, conforming to earlier studies, young clusters ($T \la 10\, \mathrm{Myr}$) have power-law TPCFs that are characteristic of fractal distributions with a fractal dimension $D_2$, and this scale-free nature extends out to a maximum scale $l_{\mathrm{corr}}$ beyond which the distribution becomes Poissonian. However, $l_{\mathrm{corr}}$, and $D_2$ vary significantly across the sample, and are correlated with a number of host galaxy physical properties, suggesting that there are physical differences in the underlying star cluster distributions. We also find that hierarchical structuring weakens with age, evidenced by flatter TPCFs for older clusters ($T \ga 10\, \mathrm{Myr}$), that eventually converges to the residual correlation expected from a completely random large-scale radial distribution of clusters in the galaxy in $\sim 100 \, \mathrm{Myr}$. Our study demonstrates that the hierarchical distribution of star clusters evolves with age, and is strongly dependent on the properties of the host galaxy environment.

We find that a rich vareity of synchronization behavior, such as in-phase, anti-phase,complete and anti- synchronization is possible. We present an approximate stability analysis for the different synchronization behaviors. The transitions to different states of synchronous behaviour are analyzed in the parameter plane of coupling strengths by numerical studies for specific cases such as Rossler and Lorenz systems and are characterized using various indices such as correlation, average phase difference and Lyapunov exponents. The threshold condition obtained from numerical analysis is found to agree with that from the stability analysis.

description: This study examined the post school outcomes for young adults with disabilities having participated in special education programs while attending high school. An electronic survey was used to collect information from a population of previous special education students ages 18 to 19 years from a school district in the state of Utah. After sending the survey to approximately 275 former students, the researcher received responses from 4 individuals; a 1.45% response rate. The survey data were examined to identify overall satisfaction of participants’ high school education. Current participant employment rates, as well as post-secondary education enrollment was examined. No conclusions could be drawn from the survey because of the inadequate response rate. Limitations of the research are discussed.

description: Internet advertising is a sophisticated game in which the many advertisers "play" to optimize their return on investment. There are many "targets" for the advertisements, and each "target" has a collection of games with a potentially different set of players involved. In this paper, we study the problem of how advertisers allocate their budget across these "targets". In particular, we focus on formulating their best response strategy as an optimization problem. Advertisers have a set of keywords ("targets") and some stochastic information about the future, namely a probability distribution over scenarios of cost vs click combinations. This summarizes the potential states of the world assuming that the strategies of other players are fixed. Then, the best response can be abstracted as stochastic budget optimization problems to figure out how to spread a given budget across these keywords to maximize the expected number of clicks. We present the first known non-trivial poly-logarithmic approximation for these problems as well as the first known hardness results of getting better than logarithmic approximation ratios in the various parameters involved. We also identify several special cases of these problems of practical interest, such as with fixed number of scenarios or with polynomial-sized parameters related to cost, which are solvable either in polynomial time or with improved approximation ratios. Stochastic budget optimization with scenarios has sophisticated technical structure. Our approximation and hardness results come from relating these problems to a special type of (0/1, bipartite) quadratic programs inherent in them. Our research answers some open problems raised by the authors in (Stochastic Models for Budget Optimization in Search-Based Advertising, Algorithmica, 58 (4), 1022-1044, 2010).

description: The formulation of good academic paper titles in English is challenging for intermediate English authors (particularly students). This is because such authors are not aware of the type of titles that are generally in use. We aim to realize a support system for formulating more effective English titles for intermediate English and beginner authors. This study develops an extractive title generation system that formulates titles from keywords extracted from an abstract. Moreover, we realize a title evaluation model that can evaluate the appropriateness of paper titles. We train the model with titles of top-conference papers by using BERT.

title: NetTest: An Integrated Web-Based Test Tools
Creators: name: Yang, Tzy-Tao
Publisher: name: Utah State University
Year: 1997

description: This report presents the design and implementation of NetTest; a Java program that can be run within a Java enabled Web browser. NetTest is a Web-based test tool, which allows instructors to create or edit tests and students to take tests using a Java-enabled Web-browser. It also allows managers to perform their tasks using similar tools.
NetTest is a server/client program, which is located on the server. While using the NetTest system, the Web browser will automatically download the program and execute it on the client machine. In other words, NetTest can be run on any kind of network environment as long as the network supports the TCP/IP protocol. It can be run on the Internet, an Intranet, a WAN, or a LAN.
NetTest is a cross-platform program, for which the servers and clients can be any kind of platforms and the source code needs not be modified or recompiled.
This report examines the structure of the NetTest with several Object-Oriented models. The structure of the NetTest database is illustrated by using data flow diagrams and table definitions. A preliminary user manual is also included.
A synchronous generator model for the U.B.C. electromagnetic transients program
Creators: name: Martinich, Terrence Gordon
Publisher: name: University of British Columbia
Year: 2010

description: In recent years, problems have arisen with electro-mechanical interaction in turbine-generator units in power systems. This torsional interaction between the mechanical shaft system and electrical system occurs in the subsynchronous resonance phenomenon, that may arise in series compensated transmission lines, and in faulty synchronization. Shaft torques caused by these disturbances may be sufficiently severe as to damage or destroy the turbine-generator shaft. Therefore, to study these cases, there was a need to represent generators in digital computer transients programs in more detail than as simple voltage sources behind reactances. Addition of a synchronous generator model to the U.B.C. Transients Program is described. The model of the generator represents both the electrical and shaft torsional dynamics and possesses a large degree of generality. The model assumes constant excitation and no magnetic saturation of the iron in the machine. Interface to the Transients Program is through a three-phase Thevenin equivalent circuit of the external electric network as seen from the generator terminals. Trapezoidal rule implicit integration is applied to the machine equations followed by use of Newton's method to solve the resulting nonlinear algebraic equations. Test cases are presented to verify the new solution technique, followed by examples of possible applications of the synchronous machine model. In a study of faulty synchronizations of an unloaded generator, conclusions were in agreement with the findings of a manufacturer.

title: JeroMF: A Software Development Framework for Building Distributed Applications Based on Microservices and JeroMQ
Creators: name: Jain, Aditi
Publisher: name: Utah State University
Year: 2019

description: This report describes a project involving the design, implementation, and testing of a software development framework, called JeroMF, that can help developers create scalable distributed applications based on a microservice architecture and that uses JeroMQ (a native Java implementation of ZeroMQ) for message passing. JeroMF provides an execution framework and extensible components for implementing processes, services, communication channels, messages, communication statistics, and encryption. Applications built with JeroMF do not require a message broker or any other middleware processes. However, they may include an optional Service Registry that can facilitate for service discovery and secure communications. The Service Registry itself was implemented with JeroMF and is included as part of the JeroMF distribution. Thorough unit, integration and system test cases exist for every component of JeroMF. For validation, JeroMF was used to re-design and re-implement a distributed health-care application with 13 separate types of services and very strict security requirements.
title: Assessing Beaver Dam Dynamics in the Logan-Little Bear Watershed
Creators: name: Penrod, Connor
Publisher: name: Utah State University
Year: 2019

description: This paper seeks to address a knowledge gap concerning how flood events impact beaver dams over time. To address this gap, I took four time-snapshots of beaver dams, mapping them across the Utah portion of the Logan-Little Bear watershed, from 2009 to 2016 to bookend a large flood event in 2011. I assessed dam status (intact, breached, or blown out) for each dam mapped to assess the impact of the large spring runoff on the dam status. Assessing dam status over time allowed me to assess the change in condition over time, from before to several years after, while also allowing me to visualize the change in dam locations throughout the watershed. I was curious if floods impacted dams in any statistically significant way. If floods do impact dams, are the breached and blown out dams repaired, or are they abandoned? How long until dams across the watershed returned to pre-flood conditions?
I found that, following 2011, there was a temporary decrease in the overall number of dams mapped. However, in ensuing years the total number of dams surpassed the baseline. There was a notable impact following the 2011 spring runoff, with a large percentage of 2011 dams existing in a breached or blown out state, and conditions had not returned to pre-flood levels before another flood in 2017. A large number of dams did not overlap between 2011 and 2014, possibly indicating beaver had moved into new locations. Dams and complexes that had been abandoned in 2011 were often reoccupied or rebuilt by 2016. The data gathered in the course of this study indicates that large floods act as mechanisms impacting beaver dam dynamics in the Logan-Little Bear watershed.
A Small Step on the Long Road to Understanding the R-Stars: CNO Cycling in Candidate R-Star Progenitors

description: Recent work has proposed that a merger event between a red-giant and a He white dwarf may be responsible for the production of R-stars (Izzard et al, 2007). We investigate the proposed evolution and nucleosynthesis of such a model. We simulate the hypothesized late ignition of the core flash by increasing the neutrino losses until the ignition occurs sufficiently far from the centre that the subsequent evolution produces dredge-up of carbon to the extent that the post-flash object is a carbon star. Detailed nucleosynthesis is performed within this approximation, and we show that the overall properties are broadly consistent with the observations. Details will depend on the dynamics of the merger event.

Stability of large complex systems with heterogeneous relaxation dynamics

description: We study the probability of stability of a large complex system of size $N$ within the framework of a generalized May model, which assumes a linear dynamics of each population size $n_i$ (with respect to its equilibrium value): $ \frac{\mathrm{d}\, n_i}{\mathrm{d}t} = - a_i n_i - \sqrt{T} \sum_{j} J_{ij} n_j $. The $a_i>0$'s are the intrinsic decay rates, $J_{ij}$ is a real symmetric $(N\times N)$ Gaussian random matrix and $\sqrt{T}$ measures the strength of pairwise interaction between different species. Unlike in May's original homogeneous model, each species has now an intrinsic damping $a_i$ that may differ from one another. As the interaction strength $T$ increases, the system undergoes a phase transition from a stable phase to an unstable phase at a critical value $T=T_c$. We reinterpret the probability of stability in terms of the hitting time of the level $b=0$ of an associated Dyson Brownian Motion (DBM), starting at the initial position $a_i$ and evolving in `time' $T$. In the large $N \to \infty$ limit, using this DBM picture, we are able to completely characterize $T_c$ for arbitrary density $μ(a)$ of the $a_i$'s. For a specific flat configuration $a_i = 1 + σ\frac{i-1}{N}$, we obtain an explicit parametric solution for the limiting (as $N\to \infty$) spectral density for arbitrary $T$ and $σ$. For finite but large $N$, we also compute the large deviation properties of the probability of stability on the stable side $T < T_c$ using a Coulomb gas representation.

While pursuing the Master’s degree, the author also served as an instructor, teaching assistant, and research assistant in the Chinese program. Thus, this work is framed by the author's personal reflection accumulated from her day-to-day teaching experiences and class observations.
The portfolio consists of three major sections: (1) teaching perspectives, (2) research perspectives, and (3) an annotated bibliography. With the aim to identify the elements of an effective and communicative learning environment for Chinese language learners in a foreign setting, the author analyzes both the facilitating parameters in an at-home learning environment and the study abroad context. The author also explores the topics of Digital Story Telling and teaching pragmatics.
This portfolio is intended to benefit teachers of the Chinese language and culture that seek to build a fruitful learning environment in their classrooms around the world.
The development of a reactive power management technique for a planning environment
Creators: name: Garrett, Bretton Wayne
Publisher: name: University of British Columbia
Year: 2010

description: A computer-aided algorithm is developed for the management of reactive power flow in an electric power system. The technique is designed to assist transmission planning engineers in establishing satisfactory base-case power flow solutions. The objective in the algorithm is to reduce real power loss in the system through control of reactive power flow, and so is different than conventional "VAr allocation" algorithms. The minimisation is performed by a specially adapted gradient search with a sub-optimal step-size, which can be simply incorporated into a standard Newton-Raphson power flow program. A special feature of this thesis is the presentation of a set of contour plots of the objective function versus various pairs of control variables. An analysis of these plots is presented, and is used to demonstrate the validity of the steepest descent minimisation technique for this problem. Comments are given on tests conducted with this technique on a typical British Columbia Hydro and Power Authority power flow simulation consisting of 245 busses and 327 branches, with 47 controllable generators and 44 controllable variable-tap transformers. The algorithm is claimed to be effective and efficient for studies of this size.

title: Modern Uses of Assistance Animals in the USA: Definitions, Access, and the Laws that Protect Them
Creators: name: Reisner, Tina

description: One of the most arguable issues in our society, and within the field of modern disability policy and law is the epidemic surrounding the use of service animals. With several cases for and against the use of service animals in public entities, there is constant discussion of what is a legitimate service animal and who is able to utilize them. In this thesis, I establish the definition of disability and discuss the laws and policies that legitimized the use of service animals within the public sphere. Specifically, this work will draw upon genres such as policies and laws of disability, and academic research, relating to disability and service animal rights. Drawing upon these different sources, I attempt to discover what defines a legitimate service animal, emotional support animals (ESAs), and therapy animals. I also explore why ESAs and fraudulent service animals are used. By understanding the definition of service animals, ESAs, therapy animals in contrast to those that seek to pass off common pets as service animals, we can better understand the policies that protect the rights and privileges of these animals. This thesis will close with situations wherein the circumstances are not clear and provide suggestions on what to do in those circumstances.
