description: We report the discovery of HI 21-cm absorption towards the well-studied GHz Peaked-Spectrum source CTA 21 (4C 16.09) using the Arecibo Telescope on 2009 September 20 and 21. Recently, the frequency band between 700 and 800 MHz was temporarily opened up to radio astronomy when US TV stations were mandated to switch from analog to digital transmissions, with new frequency allocations. The redshifted HI frequency for CTA 21 falls within this band. CTA 21 has a complex radio structure on a range of scales. The innermost prominent components are separated by ~12 mas while weak diffuse emission extends for up to ~300 mas. The HI absorption profile that we find has two main components, one narrow, the other wider and blue-shifted. The total HI column density is 7.9 x 10^20 cm^-2, assuming a covering factor of unity and a spin temperature of 100 K. This HI absorption confirms the recently determined optical redshift of this faint galaxy of z ~ 0.907. We discuss this new detection in the light of HI absorption studies towards compact radio sources, and also the possibility that CTA 21 may be exhibiting multiple cycles of nuclear activity. This new detection in CTA 21 is consistent with a strong trend for detection of HI absorption in radio galaxies with evidence of episodic nuclear/jet activity.

description: La littérature scientifique regroupe plusieurs travaux s’intéressant au ressuage des matériaux cimentaires (béton, mortier et coulis). Cependant, les conclusions quant à l’influence des superplastifiants sur ce mécanisme ne sont pas claires voire parfois contradictoires. L’objectif de cette étude est donc d’examiner l’effet d’un superplastifiant de type polycarboxylate sur le ressuage des pâtes de ciment par une approche de caractérisation basée sur la turbidimétrie. Le ressuage des pâtes est donc mesuré à l’aide d’un analyseur de suspensions concentrées (Turbiscan Lab). L’avantage de ce dispositif réside notamment dans la mesure du ressuage « turbide » lorsque des particules fines dispersées par le superplastifiant restent en suspension [1]. Les essais ont été menés sur des pâtes de ciment formulées avec différents rapports Eau/Ciment et deux dosages en superplastifiant : un faible dosage de 0,1% (en extrait sec) et un dosage relativement élevé de 1%. Les résultats obtenus montrent que l'ajout du superplastifiant augmente la capacité de ressuage. De plus, la vitesse initiale de ressuage des pâtes à faibles rapports E/C augmente en présence de SP, alors qu’elle diminue légèrement pour les pâtes formulées avec des rapports E/C élevés. Par ailleurs, en utilisant l’approche développée initialement par Powers [2] et par la suite par Josserand et al. [3], la perméabilité des pâtes de ciment a été déterminée. Les résultats montrent que la présence du superplastifiant conduit à une diminution de la perméabilité initiale des pâtes à faibles rapports E/C et à une diminution légère pour les pâtes aux rapports E/C élevés. Bien que la désagglomération induite par le superplastifiant augmente la tortuosité du chemin d’écoulement, elle permet également de libérer l’eau piégée par les agglomérats et pourrait créer des canaux préférentiels de ressuage. Ceci pourrait ainsi expliquer en partie l’augmentation de la capacité de ressuage et les modifications de la vitesse initiale de ressuage des pâtes en présence du superplastifiant.

description: Four newest CCD eclipse timings of the white dwarf for polar UZ Fornacis and Six updated CCD mid-eclipse times for SW Sex type nova-like V348 Puppis are obtained. The detailed O-C analyses for both CVs inside period gap are made. Orbital period increases at a rate of $2.63(\pm0.58)\times10^{-11} s\;s^{-1}$ for UZ Fornacis and of $5.8(\pm1.9)\times10^{-12} s\;s^{-1}$ for V348 Puppis, respectively, are discovered in their new O-C diagrams. However, the conservative mass transfer from the secondary to the massive white dwarf cannot explain the observed orbital period increases for both CVs, which are regarded as part of modulations at longer periods. Moreover, the O-C diagram of UZ Fornacis shows a possible cyclical change with a period of $\sim23.4(\pm5.1)yr$. For explaining the observed cyclical period changes in UZ Fornacis, both mechanisms of magnetic activity cycles in the late-type secondary and the light travel-time effect are regarded as two probable causes. Not only does the modulation period 23.4yr obey the empirical correlation derived by \cite{lan99}, but also the estimated fractional period change $ΔP/P\sim7.3\times10^{-7}$ displays a behavior similar to that of the CVs below the period gap. On the other hand, a calculation for the light travel-time effect implies that the tertiary component in UZ Fornacis may be a brown dwarf with a high confidence level, when the orbital inclination of the third body is larger than $16^{\circ}$.

description: We study the depolarization of optically oriented electrons in quantum wells subjected to an in-plane magnetic field and show that the Hanle curve drastically depends on the carrier mobility. In low-mobility structures, the Hanle curve is described by a Lorentzian with the width determined by the effective g-factor and the spin lifetime. In contrast, the magnetic field dependence of spin polarization in high-mobility quantum wells is nonmonotonic: The spin polarization rises with the magnetic field induction at small fields, reaches maximum and then decreases. We show that the position of the Hanle curve maximum can be used to directly measure the spin-orbit Rashba/Dresselhaus magnetic field.

Mechanical characterization of 3D in vitro tissues
Creators: name: Vaez Ghaemi, Roza
Publisher: name: University of British Columbia

description: Brain organoids are self-assembled, three-dimensionally structured tissues that are typically derived from pluripotent stem cells. They are multicellular aggregates that can more accurately recapitulate the tissue microenvironment compared to other cell culture systems and also reproduce organ function. These stem cell-derived 3D tissues can be excellent models for investigating mechanisms of tissue formation and responses to physiological and mechanical cues. However, understanding about their mechanical properties pales in comparison, which is all the more galling in light of newfound insights about how mechanical stimuli trigger the onset of neurodegenerative conditions. Herein, formative steps are taken to fill this knowledge gap, using neurospheres were generated from murine neural stem cells and subjected to compressive forces. I generated neurospheres that exhibit stress relaxation under static compression and viscoelastic behavior at low strains. The suitability of the Tatara model for characterizing the mechanical properties of neurospheres was also evaluated. Besides, the utility of cantilevered capillary force apparatus as a broadly applicable tool to evaluate tissue mechanics by quantifying the effect that oxidative stress has on the mechanical properties of neurospheres was demonstrated. Neurospheres exhibit viscoelasticity consistent with neural tissue and document a size-dependence of their elastic moduli. Oxidative stress altered the composition, architecture and signaling within the tissues. I observed a clear correlation between oxidative stress, the chemical state of the tissues and their biophysical properties. My results confirms that non-cytotoxic oxidative stress can modulate the differentiation of neural progenitor cells. This is the first study of its kind to investigate the mechanical properties of in vitro 3D tissues. Moreover, the methodologies developed can also be used to improve the quality and safety of cell and tissue biomanufacturing processes and yields insights for establishing rheological measurements as biomarkers.

description: The ADM formalism is reviewed and techniques for decomposing generic components of metric, connection and curvature are obtained. These techniques will turn out to be enough to decompose not only Einstein equations but also covariant conservation laws. Then a number of independent sets of hypotheses that are sufficient (though non-necessary) to obtain standard ADM quantities (and Hamiltonian) from covariant conservation laws are considered. This determines explicitely the range in which standard techniques are equivalent to covariant conserved quantities. The Schwarzschild metric in different coordinates is then considered, showing how the standard ADM quantities fail dramatically in non-Cartesian coordinates or even worse when asymptotically flatness is not manifest; while, in view of their covariance, covariant conservation laws give the correct result in all cases.

title: Coordination Activities of Distributive Education Coordinators in the Secondary Schools of Utah in the Development of Training Stations and Training Sponsors
Creators: name: Stephens, Joseph D.
Publisher: name: Utah State University
Year: 1972

description: One aim of education is to provide a curriculum that will give practical experience needed to fulfill the goals of the student . Nolan, Hayden, and Malsbary have stated this goal as follows: "The curriculum must be kept up-to-date in order to provide students with the best opportunity to develop those knowledges, skills, attitudes, and understandings needed to gain entrance into and succeed in the business world ."A program in the broad field of Vocational Education which is trying to meet the needs of the student is Distributive Education. The keynote in Distributive Education (D. E.) is expressed as, 'We train them now for a career, not just a one-subject class but a total curriculum tailored to the students future needs in a well-rounded career.' In order to provide youth with this career preparation, more than traditional classroom work must be provided. One way in which Distributive Education is providing its youth with a link to reality is the cooperative method. When participating in the cooperative method, the student gains competencies in his career goal by taking instruction, part in the classroom and psrt in the business community.
The success of cooperative distributive education can be directly attributed to the ability of the teacher-coordinator to plan and conduct a wide range of coordination activities associated with classroom activities. To assure the teacher-coordinator of success in planning and conducting a wide range of coordination activities in cooperative distributive education, state and national guidelines have been made available . These guidelines are functional, showing the teacher-coordinator how to carry out the many activities needed to complete the cooperative program. Among the activities identified as essential to the cooperative program, is that of selecting training stations and training sponsors of the program. The responsibility of the teacher-coordinator is to place the right distributive education student in the right distributive education job. The main concern of this investigation is to determine the extent that the distributive education teacher-coordinators of Utah are meeting the responsibilities of proper utilization of the business community.

title: Educational Mathematical Games as an Aid to Learning with Seventh Grade Mathematics Students at Wahlquist Junior High
Creators: name: Taylor, Lewis Riley
Publisher: name: Utah State University
Year: 1972

description: One of the trends in mathematics has been the introduction of educational games as learning devices . A student's attitude toward mathematics is recognized to be very high when games are used. Walter Cronkite, on CBS television, summed up the promise of educational gaming when he said, "By participating, by playing a game , an other - wise dull subject becomes fascinating and unforgettable to the student." (Nesbitt, 1971, p. 2) Bradfield states it in this manner:
Many teachers of mathematics are unbelievably boring in their approach to teaching. Consequently , many potentially strong students never develop any great liking for mathematics. This loss of interest is an educational waste ... Therefore , a more stimulating atmosphere is needed in most mathematics classrooms . One way of stimulating the atmosphere is to use recreational mathematics material. (Bradfield, 1970, p . 239)
Stark sums up the idea of using games as an aid to learning:
The "Games Theory" is not a panacea for all educational ills, but possibly another important teaching-learning tool to prepare children for life. It could serve as an inspirational force, providing the human striving for greatness with a playground . (Stark, 1968, p . 44)
Many questions need to be answered for the teacher wanting to use mathematical games in his classroom. It will be the purpose of this paper to summarize the literature concerning the effectiveness of mathematical games in the secondary classroom. In addition, an experiment will be conducted involving the use of mathematical games in the secondary classroom and to survey the changes in attitude of the students , involved in the study, toward mathematics.

title: The Promotion of Self-Determination: A Survey of General and Special Educators

description: Learning self-determination skills is critical for all students to ensure they advocate for themselves and participate in a seamless transition from the secondary school setting to college and career. This quantitative study surveyed 224 general education, 37 mild/moderate special education, 10 severe special education, 28 alternative high general educators, 5 alternative high special educators, 3 transition special educators’ mild/moderate, and 8 special education severe teachers in a suburban school district in the western US. A rating scale and open-ended questions were used to assess the degree to which teachers provide students with instruction and require students to demonstrate self-determination/self-advocacy skills. A rating scale was used to determine the extent to which teachers use essential program characteristics. Teachers selected (a) strategies, (b) measurements of progress, and (c) curricula they used to teach self-determination. Findings demonstrated that teacher’s valued and taught self-determination/self-advocacy skills within their curriculum. However, teachers used their own teacher-developed strategies and curricula rather than evidence-based strategies. The author discusses using essential program characteristics, multidisciplinary teams, and systematic procedures to address areas to strengthen within departments and across curriculum.

description: We report a search for new gravitational physics phenomena based on Einstein-Cartan theory of General Relativity including spacetime torsion. Starting from the parametrized torsion framework of Mao, Tegmark, Guth and Cabi, we analyze the motion of test bodies in the presence of torsion, and in particular we compute the corrections to the perihelion advance and to the orbital geodetic precession of a satellite. We describe the torsion field by means of three parameters, and we make use of the autoparallel trajectories, which in general may differ from geodesics when torsion is present. We derive the equations of motion of a test body in a spherically symmetric field, and the equations of motion of a satellite in the gravitational field of the Sun and the Earth. We calculate the secular variations of the longitudes of the node and of the pericenter of the satellite. The computed secular variations show how the corrections to the perihelion advance and to the orbital de Sitter effect depend on the torsion parameters. All computations are performed under the assumptions of weak field and slow motion. To test our predictions, we use the measurements of the Moon geodetic precession from lunar laser ranging data, and the measurements of Mercury's perihelion advance from planetary radar ranging data. These measurements are then used to constrain suitable linear combinations of the torsion parameters.
title: Size and Book-to-Market Factors in Returns

description: Fama and French (Multifactor Explanations of Asset Pricing Anomalies, The Journal of Finance, March 1996) showed that average returns on common stocks are related to firm characteristics like size, earnings/price, cash flow/price, book-to-market equity, past sales growth, long-term past return, and short-term past return. These factors are considered anomalies because they are not included in theoretical models like the CAPM. In replicating their analyses, I find that firm size and the book-to-market of equity explain a large portion of the average excess returns on common stocks.

title: A More Perfect User Fee: Examining the Viability of a Vehicle Miles Traveled Fee as an Alternative to the Gas Tax
Creators: name: Hansen, Heath
Publisher: name: Utah State University
Year: 2015

description: The United States is currently facing a highway funding crisis. Both federal and state transportation budgets are under mounting duress as road maintenance and construction costs continue to outpace revenues each year. While a number of factors contribute to this problem, one of the primary causes is the inherently flawed nature of gas taxes, which provide the vast majority of revenues for the nation’s surface transportation system.
In response to growing budgetary shortfalls and the increasingly apparent shortcomings of gas taxes, state and federal policymakers have begun searching for an alternative approach to funding and financing roads. Recently, a concept known as a vehicle miles traveled (VMT) fee has gained popularity among transportation policy experts and policymakers as a potential replacement for the gas tax. Under a VMT fee system, drivers pay for their actual road use instead of, as now, for the motor fuel they consume. Although the concept is new and there exists very little real-world experience with a VMT fee, several pilot studies conducted within the last decade in the United States have demonstrated their potential as a viable, long-term solution to the nation’s road funding challenges.
In this paper, I examine the concept of VMT fees and evaluate specific VMT fee systems that have been proposed as alternatives to the gas tax. I begin with an overview of the current gas tax system in the United States and then discuss its advantages and disadvantages as well as why it is not a sustainable funding mechanism going forward. In the second section, I examine the general concept of a VMT fee, including its potential benefits, costs, and the challenges associated with transitioning from the gas tax to a VMT fee. Section three outlines seven essential criteria that specific VMT proposals should meet in order to be considered a viable alternative. In the fourth section, I evaluate four different VMT fee proposals that have been 2
tested in pilot studies in the United States based on the six criteria spelled out in Section 3. In section 5, I compare and contrast the four proposals and discuss their relative advantages and disadvantages. Section 6 concludes with recommendations for implementing a VMT fee in the United States.

Year: 2015

description: This paper replicates the paper named Human capital, capital structure, and employee pay: An empirical analysis written by Thomas J. Chemmanur, Yingmei Cheng, and Tianming Zhang in 2013. In this paper, I examine the effect of market leverage on labor expenses to prove the predictions of Titman (1984) and Berk, Stanton, and Zechner (2010). Through the OLS regression analysis, I find that market leverage has a significantly positive effect on total, cash, equity-based compensation of chief executive officers (CEOs). So an increase market leverage will always lead to an incremental labor cost, and in fact labor costs will limit the use of debt to some extent.

description: Presented 12 May, 2023 at the Center for Open and Reproducible Science (CORES) Annual Meeting 2023: Open Science: Intersections with Diversity, Inclusion and Equity. In this talk, I argue that community-driven methods development provides necessary structure for creating robust and reliable inferences in experimental science. I consider the role of open-source scientific software to date, highlighting features of community-driven software that encourage its relative success. I then draw on two software projects from my own research as case studies in the benefits of focused community engagement, while underscoring the challenges in pursuing this work under misaligned incentive structures. Overall, I encourage researchers to carefully consider the role that software development plays in modern experimental science and the interaction of these technical advances with social challenges.

description: What is the possibility that small-company stocks do well in early January because they are rebounding from year-end tax-loss selling? In the economic state we live in today, why would you not think the probability of this happening is high? Everyday people and companies seek for little ways to create, save, or spend money in an efficient way that is profitable for their own benefits. With this optimistic view, the goal of financial research is to help everyday people and business men and woman make better decisions to further enhance their decisions and profitability capability. In this research, we will replicate Richard Roll’s 1963-1980 research to determine what the true impact of information and timing can have on your profitability capability with confidence, and allowing each assumption to stand (or fall) on its own merit through research and explanatory data.

description: The Federal Reserve defines “monetary policy” as any strategy that influences money and credit, which further affects GDP. These policies are used to promote maximum employment, stable prices and moderate long-term interest rates. Generally, these policies can be differentiated by the choice of target variables. Examples of monetary policy includes exchange rate targeting, monetary targeting, among others. This paper will look at inflation targeting and investigate its effect on macroeconomic variables.

description: The dynamical fluctuations of kaon--to--pion ratios have been studied over a wide range of center--of--mass energies $\sqrt{s}$. Based on changing phase space volume which apparently is the consequence of phase transition from hadrons to quark--gluon plasma at large $\sqrt{s}$, single--particle distribution function $f$ is assumed to be rather modified. Varying $f$ and phase space volume are implemented in the grand--canonical partition function, especially at large $\sqrt{s}$, so that hadron resonance gas model, when taking into account the experimental acceptance and quark phase space occupation factor, turns to be able to reproduce the dynamical fluctuations over the entire range of $\sqrt{s}$.

title: Situating Structural Violence Within Peace: A Critical Study of Peacebuilding in Rwanda and Cambodia
Creators: name: Reeder, S. L.
Publisher: name: Utah State University
Year: 2015

description: Many peace agreements fail despite external mediation and intervention, prompting a deconstruction of the predominant conceptions of peace and methods of peacebuilding. Of the weaknesses of these conceptions, the lack of concern for post-conflict structural violence is one of the strongest, and the main focus of this research. Infant mortality rate variations demonstrate the salience of structural violence in post-conflict situations. Further, to look deeper at the weaknesses of the hegemonic ideals on peace and its implementation by external actors, the cases of Rwanda and Cambodia are analyzed using the comparative method, and situated within critical peace literature. The comparison finds that rapid military integration may cause violence to restart, and that non-state entities appear more likely to be disarmed than recognized states during the post-conflict phase. This research also suggests that not disarming rebels in the peace process is an indication of a move towards a more just and inclusive society that will lead to a decrease in both direct and indirect violence, including a decrease in structural violence as indicated by a decline in the infant mortality rate.

description: We systematically study dijet production in various processes in the small-$x$ limit and establish an effective $k_t$-factorization for hard processes in a system with dilute probes scattering on a dense target. We find that the well-known Weizsäcker-Williams gluon distribution can be directly probed in the quark-antiquark jet correlation in deep inelastic scattering and the dipole gluon distribution can be directly measured in the direct photon-jet correlation in $pA$ collisions. In the large-$N_c$ limit, the unintegrated gluon distributions involved in other different dijet channels in pA collisions are shown to be related to two widely proposed ones: the Weizsäcker-Williams gluon distribution and the dipole gluon distribution.

description: In percolating networks of mixed metallic and semiconducting CNTs, there is a tradeoff between high on-current (dense networks) and high on/off ratio (sparse networks in which the metallic CNT fraction is not percolating). Experiments on devices in a transistor configuration and Monte Carlo simulations were performed to determine the scaling behavior of device resistivity as a function of channel length (L) for CNT density p in the range 0.04 - 1.29 CNT/μm^2 in the on- and off-states. Optimized devices with field-effect mobility up to 50 cm^2/Vs at on/off ratio > 10^3 were obtained at W = 50 μm, L > 70 μm for p = 0.54 - 0.81 CNTs/μm^2.

description: When I was five, my parents walked my older brother and me into what would become our bedroom. It had walls of bare cement, and they told us we could choose to paint it whatever color we wanted. My brother, the seven-year-old self-declared animal and nature expert, and I, his loyal follower, chose forest-green walls for trees, a gold-yellow ceiling for the sun, and dirt-brown carpeting for earth—mimicking the environment in Philadelphia, Pennsylvania, from which we had just moved to Amman, Jordan. That room, with its colored reminiscence of the world of my early childhood, would serve as the backdrop to the stories my father and I would create together with the characters he adopted; Andy the raccoon, Otty the otter, and Supercamel the, well, camel were both my childhood friends and the earliest figures of my imaginative realm, linkages to my earliest memories—albeit broken—in Philadelphia. Later, as a teenager, the room served as a canvas to my solitary expression. My brother having moved out years before, I adorned its walls with black marker and white chalk. Delicate filigree flora soon grew out of my bookcases, my desk, my closet and my windows like field bindweed. I called it doodling. The room remained like that, green walls and floral doodles, until I left to complete my Master’s Degree in English in Logan, Utah. I was twenty one.

description: The use of the seniority quantum number in many-body systems is reviewed. A brief summary is given of its introduction by Racah in the context of atomic spectroscopy. Several extensions of Racah's original idea are discussed: seniority for identical nucleons in a single-$j$ shell, its extension to the case of many, non-degenerate $j$ shells and to systems with neutrons and protons. To illustrate its usefulness to this day, a recent application of seniority is presented in Bose--Einstein condensates of atoms with spin.

description: Is financial innovation good or bad? Finance research analyzes data in an attempt to answer this and many other questions. This paper seeks to determine at least a partial answer to this question for one particular financial innovation, the inverse ETF. We look at how the introduction of the first inverse ETF affects the market quality of the component stocks. We find that volatility and illiquidity of the component stocks decreases relative to the rest of the market, on average, after the introduction of the first inverse ETF. We also find that short selling increases in the component stocks relative to the rest of the market. We further our analysis and find that there is a positive relationship between the increased level of short selling and both volatility and liquidity. Therefore, we conclude that the improved market quality of the component stocks is attributable directly to the inverse ETF and not to the increased level of short selling.

description: Climate models have become an important tool in the study of climate and climate change, and ensemble experiments consisting of multiple climate-model runs are used in studying and quantifying the uncertainty in climate-model output. However, there are often only a limited number of model runs available for a particular experiment, and one of the statistical challenges is to characterize the distribution of the model output. To that end, we have developed a multivariate hierarchical approach, at the heart of which is a new representation of a multivariate Markov random field. This approach allows for flexible modeling of the multivariate spatial dependencies, including the cross-dependencies between variables. We demonstrate this statistical model on an ensemble arising from a regional-climate-model experiment over the western United States, and we focus on the projected change in seasonal temperature and precipitation over the next 50 years.

title: Teaching English as a Foreign Language: A Multicultural Perspective
Creators: name: Alotaibi, Nouf Ali
Publisher: name: Utah State University
Year: 2015

description: This portfolio is a compilation of the author’s beliefs and practices of what constitutes effective second language teaching. It is based on the author’s teaching philosophy and the work has been done during two years of study at the Master of Second Language Teaching (MSLT) program. The teaching philosophy centers on how to implement communication inside the language classroom, develop literacy, integrate culture teaching into language instruction, and how to use technology to facilitate language learning and teaching. The teaching philosophy is followed by three artifacts, which review the literature addressing different topics on language, literacy, and culture. The language artifact discusses the concept of error correction in the language classroom, the literacy artifact presents the use of dialogue journals to develop writing abilities, and the culture artifact addresses teaching the appropriate ways of performing refusals in English. Finally, the portfolio is extended and concluded by an annotated bibliography exploring the four themes of the teaching philosophy.

Assessing the vulnerability of small-scale water resources using high spatial resolution remote sensing

description: Water stress due to physical scarcity and poor water quality impacts billions of people worldwide. Internationally, an important goal of the United Nations’ Sustainable Development Goals (SDGs) is the improvement of ambient water quality by tracking the proportion of inland water bodies with acceptable water quality. Thus, there is a global, pressing need for fast, reliable, and accessible ways to monitor the water quality in small inland water bodies. In this research, I evaluate the utility of high spatial resolution remote sensing for monitoring water quality constituents (Chlorophyll-a and turbidity) in small reservoirs (0.01 km²) in southwestern Kenya. First, I used a novel combination of remote sensing indices and landscape features to build statistically robust empirical models of water quality parameters that were measured in situ. I then used these models to extrapolate water quality in 60 reservoirs over 43 consecutive months (2019-July 2022) across a land-use gradient. These results were then used to examine patterns in water quality across space and time. Finally, I used high spatial resolution imagery to quantify the areal change (or drying out) of reservoirs throughout a single dry season. Overall, Sentinel-2 satellite imagery produced better models of Chl-a (R² = 0.66) when compared to PlanetScope imagery which produced more accurate maps of turbidity (R² = 0.72). Furthermore, introducing landscape features such as land cover, maximum reservoir size, and proximity to roads improved the statistical power of models by as much as 9%. Turbidity was marginally significantly different in reservoirs across the land-use gradient, with the transition zone having the most turbid reservoirs. From 2019 to 2022, Chl-a and turbidity have been steadily improving in 46% and 40% of reservoirs, respectively. Notably, Chl-a concentrations have been improving more rapidly in the cropland zone. Additionally, nearly half of reservoirs lost over 50% of their surface area during the 2021 dry season, a period of exceptionally intense drought; whereas a quarter of all reservoirs dried out completely. This research has the potential to help support monitoring and planning within the water resources sector by prioritizing the use of climate resilient infrastructure such as water pans.
title: Woman, Wife, Mother-Saint, Scholar, Patriot: LaVon W. Laursen Papers, A Case Study of Utah Women in Politics

description: Compared to others of their era, Latter-day Saint women in Utah enjoyed a relative gender equality in voting and politics in the late nineteenth and early twentieth century. Utah was one of the first states to have equal voting rights and it had the first female state senator in 1896. Religious doctrine once positively influenced gender equality in politics; but over a century since statehood, that same doctrine has led to the decline in Utah’s female representation due to its unchanging nature in a changing society.
This paper gives pertinent background information and explores the importance of Laursen’s political activity to give relevance to her archival collection. Even though it will not give a thorough narrative of the Utah woman’s political experience, Laursen’s involvement provides context for the current political climate for women in Utah compared with its past.
During the 1980s and 1990s, a there was a resurgence of women elected to state political offices. One woman who was politically active during this time was LaVon W. Laursen. She ran for office and served as the Vice-Chair and Chair of the Utah County Democratic Party. Her papers document her own political activity and that of other women in Utah. With evidentiary support from the Laursen collection, this Plan B Thesis - a curating project - accompanied by this paper, demonstrates that women’s evolving roles, the influence of the Church of Jesus Christ of Latter-day Saints, and, according to LaVon, the local (Utah County) social views are the reasons for the fluctuation in women’s political activity.

description: We present a real-time method to determine the beam propagation ratio M2 of laser beams. The all-optical measurement of modal amplitudes yields M2 parameters conform to the ISO standard method. The experimental technique is simple and fast, which allows to investigate laser beams under conditions inaccessible to other methods.
