description: Most of the observed and simulated galactic bars are symmetric in the face-on view. However, there are indeed cases of bars that are off-center with respect to the disk or have an asymmetric shape. The only well-known example showing both these features is the Large Magellanic Cloud. We report on the identification of several lopsided galactic bars in the Illustris TNG100 simulation found among a sample of elongated bar-like galaxies studied in the past. The bars show a clear asymmetry in the face-on view, which is in the shape of a footprint. We measured the evolution of the different parameters of the bars' shape and asymmetry as a function of time and find that the asymmetry is preserved for a few Gyr. It can grow together with a bar or appear later, after bar formation. We considered two scenarios leading to the formation of lopsided bars using controlled simulations. In the first, a Milky Way-like galaxy interacts with a massive companion placed on a radial orbit in the plane of the disk and perpendicular to the orientation of the bar at the time of the first passage. In the second, the galaxy initially has an off-center disk and the growth of the bar and its asymmetry is more similar to the one found in IllustrisTNG galaxies, where it is also preceded by the presence of an asymmetric disk. It is thus possible that lopsided bars are born in lopsided disks, although in some cases, the time difference between the occurrence of the asymmetry in the two components is quite large.

title: Evaluating the Effect of the Removal of Non-Native Trout in Two High Elevation Tributary Streams in the Intermountain West
Creators: name: Brunson, Clint
Publisher: name: Utah State University
Year: 2020

description: Native fish species such as Bonneville Cutthroat Trout (BCT) require cold, clear, well-connected streams for spawning and rearing as well as access to complimentary habitats. Increasing river temperatures and lower water flows may have allowed non-native Brown Trout (BNT) to migrate into higher elevation pristine streams. Additionally, anthropogenic actions such as stocking non-native Brown and Brook (BKT) and Rainbow Trout (RBT) for angling opportunities impact BCT. Invasion of these tributaries by non-native species may reduce or eliminate cutthroat trout by predation, competition, displacement, genetic suppression, and exclusion. A seven-fold increase in BNT numbers of 50 to 350 from 2017 to 2018 demonstrated the need for this research. The goal of this project was to assess the density and distribution of non-native BNT and BKT, conduct a complete mechanical removal of BNT and BKT, and reconstruct the history of the expansion of BNT and BKT in the Temple Fork and Spawn Creek tributaries of the Logan River, UT, USA. In order to meet this goal we used pre-existing sampling data, conducted removal efforts on Temple Fork and Spawn Creek, and analyzed historical data of when BNT and BKT first appeared in sampling efforts in these locations. Our sampled locations were 400m to 500m in length on Temple Fork from the confluence with Logan River and also on Spawn Creek. We identified all captured fish and BNT and BKT were removed. We observed a surprisingly high number of BNT (2,551) and BKT (566). We did not observe BNT above reach 9 on Temple Fork and reach 6 on Spawn Creek. We were encouraged to find high numbers of BCT though BNT numbers have been increasing as previously mentioned. We demonstrated by capturing 6 BNT that a permanent selective barrier at the confluence of the Logan River and Temple Fork was not be necessary to prevent the high numbers of brown trout from invading this tributary each fall to spawn. A second trapping effort with the picket weir may further help identify movements of BNT (Figure 11). While immigration of BNT into Temple Fork from the Logan River may contribute BNT in the lower reaches of Temple Fork, ultimately the establishment of a resident population of BNT and BKT threatens to overwhelm BCT. Further actions such as additional mechanical removal efforts every other or every third year and fishing regulation changes may be warranted to protect BCT from further invasion throughout this tributary, range-wide, and where native fish populations struggle from similar concerns.
title: Weber Basin Water Conservancy District Bottom-Up Climate Vulnerability Study Using RiverWare
Creators: name: Everitt, Jacob
Publisher: name: Utah State University
Year: 2020

description: With so much uncertainty of what the future has in store for us, how can we prepare for what lies ahead? The Weber Basin Water Conservancy District (WBWCD) needs to know how they can best prepare for future climate changes and future growth, and where their water system is vulnerable. A bottom-up approach can be used to consider how factors and subfactors effect the vulnerability of their water system's storage and delivery. This approach is accomplished with the use of RiverWare, an advanced water system modeling program. Scenarios to represent the factors are as follows: range of future stream flows, future water demands, reservoir sedimentation, and future reservoir evaporation. The scenarios are input into the RiverWare model created by the Utah Division of Water Resources (UDWRe). The model is then modified to run 324 model runs of combined possible model inflows, demands, reservoir sedimentation and reservoir evaporation. Calculated shortages of water and storage levels in reservoirs are output from the RiverWare model. These outputs from the 324 RiverWare model runs are then compiled and analyzed using selected drought metrics to tell us where the WBWCD is vulnerable to climate changes and population growth.
The analysis of the shortages and storage levels shows that historically the WBWCD does not face water shortages, with the average annual demands and inflow not ever going below the moderate drought storage metric level of 380 thousand acre-feet (TAF) per year in the simulated 30-year time period. As demand increases an additional 100 TAF per year from historical levels and/or when inflows decrease by 100 TF per year from historical levels the total storage level is more likely to go below 380 TAF, signaling moderate drought. Reservoir sedimentation at reservoir storage levels lower than 280 TAF, the extreme drought storage level, does not have a large impact on how much storage is in the reservoir storage. As sedimentation rises storage is more sensitive to the change in inflows than to change in demands. The overall impact that reservoir evaporation has on storage and water demand is small.

description: The rapid development of IoT applications and their use in various fields of everyday life has resulted in an escalated number of different possible cyber-threats, and has consequently raised the need of securing IoT devices. Collecting Cyber-Threat Intelligence (e.g., zero-day vulnerabilities or trending exploits) from various online sources and utilizing it to proactively secure IoT systems or prepare mitigation scenarios has proven to be a promising direction. In this work, we focus on social media monitoring and investigate real-time Cyber-Threat Intelligence detection from the Twitter stream. Initially, we compare and extensively evaluate six different machine-learning based classification alternatives trained with vulnerability descriptions and tested with real-world data from the Twitter stream to identify the best-fitting solution. Subsequently, based on our findings, we propose a novel social media monitoring system tailored to the IoT domain; the system allows users to identify recent/trending vulnerabilities and exploits on IoT devices. Finally, to aid research on the field and support the reproducibility of our results we publicly release all annotated datasets created during this process.

title: Straight Men Come Out: Queer Eye and the Path to a More Mindful Masculinity
Creators: name: Roush, Eli M
Publisher: name: Utah State University
Year: 2020

description: My thesis explores the culture surrounding the 2018 reboot of Queer Eye for the Straight Guy in relation to contemporary arguments in masculinity studies about the costs of hegemonic masculinity, performance, and identity. This paper examines how Queer Eye carefully creates space where heteronormative men can safely express emotional vulnerability and embody a more functional masculinity that expands beyond the bounds of hegemonic performance. The bulk of the analysis involves close readings of specific episodes and scenes from Queer Eye that introduce and examine the strategies the Fab Five use to redefine their subject's engagement with masculinity, explore the effectiveness of these strategies, and evaluate their potential to be used as a model to create spaces for struggling heteronormative men. This analysis, along with a theoretical framework provided by scholars in the field of masculinity studies, provides insight into and better define terms like "crisis of masculinity" and "toxic masculinity,” which oversimplify deeper issues of shifting gender norms and privilege that are affecting American society. I hope that this work can contribute to solving our current "crisis of masculinity" by providing insight into potential methods that enable men to embody an unconstrained, individualized, masculinity and deconstruct the source of toxic expression that limits them.

description: We study a class of planar billiards having the remarkable property that their phase space consists up to a set of zero measure of two invariant sets formed by orbits moving in opposite directions. The tables of these billiards are tubular neighborhoods of differentiable Jordan curves that are unions of finitely many segments and arcs of circles. We prove that under proper conditions on the segments and the arcs, the billiards considered have non-zero Lyapunov exponents almost everywhere. These results are then extended to a similar class of of 3-dimensional billiards. Finally, we find that for some subclasses of track billiards, the mechanism generating hyperbolicity is not the defocusing one that requires every infinitesimal beam of parallel rays to defocus after every reflection off of the focusing boundary.

title: An Examination of Co-Teacher's Instructional Practices and Social Validity Following Participation in Professional Development
Creators: name: Sitton, Jessica
Publisher: name: Utah State University
Year: 2019

description: Because co-teaching teams often lack the support to continue to implement the evidence-based strategy of co-teaching beyond initial training and coaching sessions, this project studies the affect of training and coaching on teacher implementation and social validity following participation in co-teaching professional development. The Utah State Board of Education – Special Education (USBE-SES), from years 2012-2019, along with the Utah Professional Development Network (UPDN), from years 2014-2019 provided training, support and coaching to secondary co-teaching teams tied to the content areas of secondary mathematics and secondary English language arts (ELA). This project studied the continued use of instructional components specific to co-teaching models one, two, and three years after participants completed a yearlong training and coaching professional development . The elements examined include (a) continued use of co-teaching, (b) types and frequency of models currently used, (c) the use of co-planning and other forms of collaboration, (d) co-instructing throughout the class period and school year, and (e) the perceived improvement for general and special education students. Participants included secondary (grades 6-12) co-teaching teams from Utah districts and charter schools who participated in the USBE-SES and UPDN mathematics and English language arts (ELA) co-teaching yearlong training sessions between the 2015-2019 school years. Participating co-teachers completed an electronic survey which included questions related to their teaching demographics, the extent to which they were still implementing co-teaching practices described in the USBE-SES and UPDN trainings, and their views of co-teaching. The researcher predicted that the latency between participation in their co-teaching training session and the date of the survey would show less frequent use of co-teaching models. The opposite was observed in the collected data. The 2015-2016 cohort reported the highest mean of implementing two or more co-teaching models during their 2018-2019 school year. The researcher also predicted that co-teaching teams would report a noticeable benefit to students with disabilities (SWD) due to an increase of academic knowledge and prosocial behavior. Survey data showed that the two social validity statements addressing increased academic and prosocial knowledge for SWD were among the highest rated overall and across subgroups. Obtained results will be shared with USBE-SES and UPDN personnel involved in the co-teaching training delivery, so they may choose to incorporate this data on fidelity of implementation post training when designing instruction, support practices and coaching for future co-teaching trainings years.

description: The aim of this paper is to analyze different regulation mechanisms in spatial continuous stochastic development models. We describe the density behavior for models with global mortality and local establishment rates. We prove that the local self-regulation via a competition mechanism (density dependent mortality) may suppress a unbounded growth of the averaged density if the competition kernel is superstable.

description: One of the main bottleneck issues for room-temperature antiferromagnetic spintronic devices is the small signal read-out owing to the limited anisotropic magnetoresistance in antiferromagnets. However, this could be overcome by either utilizing the Berry-curvature-induced anomalous Hall resistance in noncollinear antiferromagnets or establishing tunnel junction devices based on effective manipulation of antiferromagnetic spins. In this work, we demonstrate the giant piezoelectric strain control of the spin structure and the anomalous Hall resistance in a noncollinear antiferromagnetic metal - D019 hexagonal Mn3Ga. Furthermore, we built tunnel junction devices with a diameter of 200 nm to amplify the maximum tunneling resistance ratio to more than 10% at room-temperature, which thus implies significant potential of noncollinear antiferromagnets for large signal-output and high-density antiferromagnetic spintronic device applications.

description: The hidden-charm tetraquarks with strangeness, $c\bar{c}s\bar{q}$ $(q=u,\,d)$, in $J^P=0^+$, $1^+$ and $2^+$ are systematically investigated in the framework of real- and complex-scaling range of a chiral quark model, whose parameters have been fixed in advance describing hadron, hadron-hadron and multiquark phenomenology. Each tetraquark configuration, compatible with the quantum numbers studied, is taken into account; this includes meson-meson, diquark-antidiquark and K-type arrangements of quarks with all possible color wave functions in four-body sector. Among the different numerical techniques to solve the Schrödinger-like 4-body bound state equation, we use a variational method in which the trial wave function is expanded in complex-range Gaussian basis functions, which is characterized by its simplicity and flexibility. This theoretical framework has already been used to study different kinds of multiquark systems, such as the hidden-charm pentaquarks, $P^+_c$, and doubly-charmed tetraquarks, $T^+_{cc}$. The recently reported $Z_{cs}$ states by the BESIII and LHCb collaborations are generally compatible with either compact tetraquark or hadronic molecular resonance configurations in our investigation. Moreover, several additional exotic resonances are found in the mass range between 3.8 GeV and 4.6 GeV.

title: Visualizing Effects of Changing Base Level on Tributary Resources in Lake Powell Reservoir
Creators: name: Friend, Madeline
Publisher: name: Utah State University
Year: 2020

description: Lake Powell reservoir is the second-largest reservoir in the United States. As climate change reduces watershed runoff in the Colorado River Basin, questions arise about the management and even existence of Lake Powell. If lake levels continue to drop, what will the emerging canyon look like and what value will we assign it? Lake Powell traps all incoming fine sediment from the Colorado River, the San Juan River, and many smaller tributaries. What is the fate of this sediment under falling reservoir levels and how will it influence other resources? To support a robust public discourse, we provide an immersive ESRI StoryMap, combining a range of information in a visually compelling, user-friendly digital format. A particular focus of the StoryMap is the configuration and persistence of sediments deposited in the reservoir during previous high stands. In this document, we provide background information for stakeholders and user groups that desire to understand more about the region, reservoir and dam operations, climate change and aridification, and sediment transport. The StoryMap can be accessed at https://arcg.is/1feGiO or at https://storymaps.arcgis.com/stories/ 41b5fda81d8b47d0abe8958845fd0194.

description: The warming trend of the last decades is now so strong that it is discernible in local temperature observations. This opens the possibility to compare the trend to the warming predicted by comprehensive climate models (GCMs), which up to now could not be verified directly to observations on a local scale, because the signal-to-noise ratio was too low. The observed temperature trend in western Europe over the last decades appears much stronger than simulated by state-of-the-art GCMs. The difference is very unlikely due to random fluctuations, either in fast weather processes or in decadal climate fluctuations. In winter and spring, changes in atmospheric circulation are important; in spring and summer changes in soil moisture and cloud cover. A misrepresentation of the North Atlantic Current affects trends along the coast. Many of these processes continue to affect trends in projections for the 21st century. This implies that climate predictions for western Europe probably underestimate the effects of anthropogenic climate change.

description: In September 2016, Wells Fargo Company was fined a large amount of money due to its employees opening unauthorized accounts and credit cards under customer’s names. This paper examines the effects of the lawsuit announcement on the stock market as it pertains to finance, insurance, and real estate firms. The analysis will be completed using the cumulative abnormal returns (CARs) and various control variables through univariate and multivariate tests. The results of these tests show that the markets did not lose confidence or trust in banks. Instead, the Wells Fargo scandal generated positive CARs for other banks on the day of the lawsuit announcement.

description: Using numerical renormalization group techniques, we study static and dynamic properties of a family of single-channel Kondo impurity models with axial magnetic anisotropy $DS_z^2$ terms; such models are appropriate to describe magnetic impurity atoms adsorbed on non-magnetic surfaces, which may exhibit surface Kondo effect. We show that for positive anisotropy $D$ and for any spin $S$, the systems behave at low temperatures as regular Fermi liquids with fully compensated impurity spin. The approach to the stable fixed point depends on the value of the spin $S$ and on the ratio $D/T_K^{(0)}$, where $T_K^{(0)}$ is the Kondo temperature in the absence of the anisotropy. For S=1, the screening occurs in two stages if $DT_K^{(0)}$. For negative anisotropy $D$, the system is a non-Fermi liquid with residual anisotropic exchange interaction. However, the presence of transverse magnetic anisotropy $E(S_x^2-S_y^2)$ restores Fermi-liquid behavior in real systems.

Trench sizes of less than 30 nm in width are attainable with this technique. Besides oxidation we also show the influence of mechanical peeling and scratching with an AFM of few layer graphene sheets placed on different substrates.

description: This study investigates the effects of mass shooting events on the performance of the tourism industry within the United States. The results of the study show that outside of the market-wide returns, the performance of tourism stocks is negatively impacted after a large-scale mass shooting event. Furthermore, when separating extreme outliers in the data such as the Las Vegas Mandalay Bay shooting, the results of the study find that tourism stocks surrounding other large-scale mass shootings are significantly negative. Overall, the results of the study demonstrate a negative response in the tourism industry to large-scale mass shootings.

Publisher: name: Utah State University
Year: 2020

description: This paper focuses on oil hedging using near month crude oil futures. Hedging may allow a firm to reduce risks and focus on areas of comparative advantage. Hedging requires a firm to estimate ex-ante the correct hedge ratio. The portfolio optimization framework allows for OLS to be applied to the estimation of a hedge ratio. Reinforcement Learning is another method available to hedgers to estimate a hedge ratio. Three strategies using econometric tools and one using Reinforcement Learning are estimated and tested against 2019 oil price data.

description: We report 13C nuclear magnetic resonance measurements on single wall carbon nanotube (SWCNT) bundles. The temperature dependence of the nuclear spin-lattice relaxation rate, 1/T1, exhibits a power-law variation, as expected for a Tomonage-Luttinger liquid (TLL). The observed exponent is smaller than that expected for the two band TLL model. A departure from the power law is observed only at low T, where thermal and electronic Zeeman energy merge. Extrapolation to zero magnetic field indicates gapless spin excitations. The wide T range on which power-law behavior is observed suggests that SWCNT is so far the best realization of a one-dimensional quantum metal.

description: We have observed a sample of 9 Extended Green Objects (EGOs) at 1.3 and 5 cm with the VLA with sub-arcsecond resolution and ~7-14 uJy/beam sensitivities in order to characterize centimeter continuum emission as it first appears in these massive protoclusters. We find EGO-associated continuum emission - within 1 arcsec of the extended 4.5 um emission - in every field, which is typically faint (order 10^1-10^2 uJy) and compact (unresolved at 0.3-0.5 arcsec). The derived spectral indices of our 36 total detections are consistent with a wide array of physical processes, including both non-thermal (19% of detections) and thermal free-free processes (e.g. ionized jets and compact HII regions, 78% of sample), and warm dust (1 source). We also find EGO-associated 6.7 GHz CH$_3$OH and 22 GHz H$_2$O maser emission in 100% of the sample, and NH$_3$ (3,3) masers in ~45%; we do not detect any NH$_3$ (6,6) masers at ~5.6 mJy/beam sensitivity. We find statistically-significant correlations between radio-distance and bolometric luminosities at two physical scales and three frequencies, consistent with thermal emission from ionized jets, but no correlation between water-maser and radio-distance luminosities for our sample. From these data, we conclude that EGOs likely host multiple different centimeter continuum-producing processes simultaneously. Additionally, at our ~1000 au resolution, we find that all EGOs except G18.89$-$0.47 contain 1 to 2 massive sources based on the presence of methanol maser groups, which is consistent with our previous work suggesting that these are typical massive protoclusters in which only one to a few of the YSOs are massive.

title: A Working Ideology for Graphic Design

description: This exhibition represents an experimental body of work completed for the Caine College of the Arts. It explores the interplay of explicit and implicit functions within semiotics, while simultaneously communicating the college’s messages and honestly representing my own aesthetic ideals. Through the treatment of these explorations I hope to create an aesthetic experience for the viewer. That stems from my own ideology – which consists of a myriad of conscious and subconscious beliefs – that make up who I am as a designer.
My conception of form arises from an essentialist approach to space and shape. This conception developed out of stripping ornament and detail, leaving visible only structural and proportional elements. The treatment is sparse at times and rigorous, but strives for a type of honesty. Much of the layout is determined by mathematical forms and systematic intervals. This aesthetic is more rough and concrete than lyrical and abstract. The forms I reference are indebted to older industrial forms, including among others the ubiquitous factory folk-art of North America. They strive for functional unpretentiousness. Like the realist painters I seek inspiration from ordinary people doing their ordinary tasks.
Emphasizing the form and the aesthetic experience can create an interesting dynamic in the work. It creates visual interest but runs the risk of overthrowing its original intended function by delaying or frustrating quick comprehension. As a result, an emphasis on the implicit function, can oftentimes lead to failure because of its inherent ambiguity and decentered messaging. This work represents explorations of the limits within semiotic systems and communication and explores the aesthetic dimension and meaning within form itself.

description: In September 2021, the town of Yulin in Northwest China’s Shaanxi province substantially reduced its
production of magnesium carbonate (MgCO3), falling at least 70 percent from market expectations.
Although production generally recovered within a few weeks, China is the world’s largest magnesium
producer, and this brief shutdown created substantial ripple effects throughout the downstream
industries which incorporate magnesium into their products. Notably, the experience of the global
automotive sector, which includes electric vehicle producers, highlights the effect that dwindling
magnesium supplies can have on downstream production as magnesium is integral to strengthening and
lightening of aluminum.
This working paper will provide a snapshot of the magnesium market at the end of 2021 and place the
brief shutdown in China in context. It will begin with an introduction to the magnesium metal and a history
of its production processes, and will explore the current market for magnesium. It will then provide an
overview of major global magnesium producers and a closer look at U.S. production and the domestic
magnesium market. The paper will then note contemporary supply chain challenges in the magnesium
sector and conclude with a brief exploration of the potential future of the industry.

description: Squeezed correlations of hadron-antihadron pairs are predicted to appear if their masses are modified in the hot and dense medium formed in high energy heavy ion collisions. If discovered experimentally, they would be an unequivocal evidence of in-medium mass shift found by means of hadronic probes. We discuss a method proposed to search for this novel type of correlation, illustrating it by means of D_s-mesons with in-medium shifted masses. These particles are expected to be more easily detected and identified in future upgrades at RHIC.

Unverstanden "Unter Leuten" - Kommunikation und Heimat in Juli Zehs Gesellschaftsroman und seinen Medien-Varianten
Creators: name: Wohner, Ariane
Publisher: name: Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)
Year: 2023

description: Ausgehend von der These, dass die Figuren in Juli Zehs Gesellschaftsroman "Unterleuten" sowie seinen Medien-Varianten (Hörbuch, Hörspiel und Film) in Unterleuten keine Heimat haben oder finden können, weil die Kommunikation fast vollständig scheitert, analysiert die Arbeit detailliert die Kommunikation in verschiedenen Figurenkonstellationen: Ehe-/Liebespaare, Eltern und Kinder, außerfamiliäre Beziehungen sowie Kommunikation in größeren Gruppen. Als Hauptgrund für das Scheitern von Kommunikation – und in Folge davon Heimat – wird das strategische Handeln der Figuren, das Verfolgen von rein egozentrischen Motiven angenommen. Ein weiterer Aspekt, der das Missverstehen wesentlich mitbedingt, ist der Ost-West- bzw. Land-Stadt-Gegensatz, der nicht überwunden werden kann, da keine Seite versucht, die Perspektive der anderen einzunehmen, sondern beide in stereotypen Zuschreibungen hängenbleiben. Daneben geht es aus medienkomparatistischem Blickwinkel darum, wie Kommunikation und Heimat in Roman, Hörbuch, Hörspiel und Film dargestellt werden (können).

description: Quantum spin liquid (QSL) state in rare-earth triangular lattice has attracted much attention recently due to its potential application in quantum computing and communication. Here we report the single-crystal growth synthesis, crystal structure characterizations and magnetic properties of $A$YbSe$_{2}$ ($A$= K, Rb) compounds. The X-ray diffraction analysis shows that $A$YbSe$_{2}$ ($A$ = K and Rb) crystallizes in a trigonal space group, $R$-3$m$ (No. 166) with Z = 3. $A$YbSe$_{2}$ possesses a two-dimensional (2D) Yb-Se-Yb layered structure formed by edged-shared YbSe$_6$ octahedra. The magnetic properties are highly anisotropic for both title compounds and no long-range order is found down to 0.4 K, revealing the possible QSL ground state in these compounds. The isothermal magnetization exhibits one-third magnetization plateau when the magnetic fields are applied in $ab$-plane. Heat capacity is performed along both $ab$-plane and $c$-axis, and features the characteristic dome for triangular magnetic lattice compounds as a function of magnetic fields. Due to the change of the interlayer and intralayer distance of Yb$^{3+}$, the dome shifts to low fields from KYbSe$_2$ to RbYbSe$_2$. All these results indicate the $A$YbSe$_2$ family presents unique frustrated magnetism close to the possible QSL and noncolinear spin states.

title: Youth in World War II
Creators: name: Griggs, Alyson
Publisher: name: Utah State University

description: This thesis project consists of two focuses. The first part focuses on the experiences of Japanese American adolescents who were interned with their parents at the Central Utah Relocation Center during World War II. Although these students were born in the United States and therefore U.S. citizens, they were considered "Japanese" by the U.S. government and many of its citizens. When the U.S. government forcibly removed Japanese American youth and their families from the West Coast, this heavily affected Japanese American youth's perceptions of themselves and the country of their birth. This portion of the project includes a digital exhibit, a video exploring the living conditions at the relocation center, and a high school lesson plan.
The second portion of this project focuses on World War II experiences of Japanese and Filipino youth. Although Japan and the Philippines were enemies during World War II, many youth of both countries experienced similar levels of indoctrination, violence, and starvation—demonstrating the level of totality of the Pacific War. This portion of the project includes a digital exhibit, a paper, and a high school lesson plan.
Neutrino-Mass Hierarchies and Non-linear Representation of Lepton-Flavour Symmetry

description: Lepton-flavour symmetry in the Standard Model is broken by small masses for charged leptons and neutrinos. Introducing neutrino masses via dimension-5 operators associated to lepton-number violation at a very high scale, the corresponding coupling matrix may still have entries of order 1, resembling the situation in the quark sector with large top Yukawa coupling. As we have shown recently, in such a situation one may introduce the coupling matrices between lepton and Higgs fields as non-linear representations of lepton-flavour symmetry within an effective-theory framework. This allows us to separate the effects related to the large mass difference observed in atmospheric neutrino oscillations from those related to the solar mass difference. We discuss the cases of normal or inverted hierarchical and almost degenerate neutrino spectrum, give some examples to illustrate minimal lepton-flavour violation in radiative and leptonic decays, and also provide a systematic definition of next-to-minimal lepton-flavour violation within the non-linear framework.

description: For children displaced from conflict, attending school can be a lifeline, providing stability, learning and opportunities for socialisation. In such contexts, teachers become more than facilitators of learning as they find themselves providing social-emotional support and guidance to traumatised students and their families. Yet, teachers of refugees and other vulnerable children are often the least supported, compromising their ability to teach effectively and provide high-quality education to students. This is the case in Jordan where most Syrian refugees are taught by temporary contract teachers (TCTs), who are Jordanian nationals and typically begin teaching with little to no training or classroom experience. Although nearly all hold bachelor degrees, TCTs are precariously employed and usually paid the national minimum wage, which is a fraction of the salaries their permanently employed counterparts receive.The study’s overall research objective was to understand the effects of current hiring, training and evaluation policies and practices on TCTs’ motivation to work and their perceptions of teacher management policies, system practices and working conditions in Jordan. The study is primarily descriptive in that it assesses TCTs’ perspectives and needs, current practices and possible solutions, laying the groundwork for intervention design and testing in a later phase. The following research questions (RQs) guided the study:RQ1: What are TCTs’ motivations, challenges and experiences with hiring processes (recruitment, selection and deployment) under the current policies?RQ2: What are TCTs’ motivations, challenges and experiences with the application (or lack thereof) of current teacher evaluation and training protocols and practices?RQ3: What interventions (strategy, policy or programme) do teachers and system-level stakeholders perceive to be desirable and potentially cost-effective and scalable to improve motivation, management and support?While an associated technical brief focuses on the quantitative findings1 of the study, this brief focuses on the outcomes of the qualitative components of the study and hence focuses on the qualitative sample and results, which relate to research question 3.
