description: The dynamical breaking of chiral symmetry in QCD is caused by nonperturbative interactions on a scale rho ~ 0.3 fm, much smaller than the hadronic size R ~ 1 fm. These short-distance interactions influence the intrinsic transverse momentum distributions of partons and their correlations at a low normalization point. We study this phenomenon in an effective description of low-energy dynamics based on chiral constituent quark degrees of freedom, which refers to the large-N_c limit of QCD. The nucleon is obtained as a system of constituent quarks and antiquarks moving in a self-consistent classical chiral field (chiral quark-soliton model). The calculated distributions of constituent quarks/antiquarks are matched with QCD partons at the scale rho^{-2}. The p_T distribution of valence quarks is localized at p_T^2 ~ R^{-2} and roughly of Gaussian shape. The sea quark distribution exhibits a would-be power-like tail ~1/p_T^2 extending up to the chiral symmetry-breaking scale. Such behavior is seen in the flavor-singlet unpolarized and nonsinglet polarized sea. The high-momentum tails are the result of short-range correlations between sea quarks in the nucleon's light-cone wave function, analogous to NN correlations in nuclei. The nucleon wave function contains correlated pairs of transverse size rho << R with sigma- and pi-like quantum numbers, whose internal wave functions become identical at p_T^2 ~ rho^{-2} (restoration of chiral symmetry). These features are model-independent and represent an effect of dynamical chiral symmetry breaking on the nucleon's partonic structure. Our results have numerous implications for the P_T distributions of particles produced in hard scattering processes. The nonperturbative parton correlations predicted here could be observed in particle correlations between the current and target fragmentation regions of DIS.

description: We apply the dual-varibles approach to the problem of the optical response of an disordered film of metal particles with dipole-dipole interaction. Long range dipole-dipole interaction makes the effect of spatial correlations significant, so that dual-variables technique provides a desirable improvement of the coherent-potential results. It is shown that the effect of nonlocality is more pronounced for a medium-range concentration of the particles. The result is compared with the non-local cluster approach. It is shown that short-range correlations accounted in the cluster method reveal themselves in the spectral properties of the response, whereas long-range phenomena kept in the dual technique are more pronounced in the k-dependence of the Green's function.

title: Creation an Information Model of the Bulgarian National Embroidery for Presentation and in Knowledge Bases

description: Embroidery, as a decoration of the folk costume, is an integral part of the overall composition of the garment. It is a source of information for contemporary researchers about the aesthetic and moral norms of our ancestors, about their ancient gods, beliefs and traditions that have lost their popularity these days. Over time, the embroideries have lost the meaning of a sacral element, and many of them have been modified, geometricized and stylized, but in their infinite variety they represent an extremely valuable historical heritage. Regardless their uniqueness and diversity, national embroideries carry some compulsory elements that can be summarized and required when creating knowledge bases with information about them. A formalized model of semantic information, carried by the Bulgarian national embroidery, is presented, with a detailed description of its specifics. Along with the commonly accepted standardized forms, the characters encoded as a positive, negative or hidden element are also stored. The characteristics thus selected, make it possible to build a knowledge base such as a semantic network based on the subjective semantics of the elements. The aim is to provide an opportunity to search and display comprehensive information about an individual artefact, to study it in the context of such monuments and to create a collection for further socialization.

description: The spectroscopy of faint planetary-mass companions to nearby stars is one of the main challenges that new-generation high-contrast spectro-imagers are going to face. In a previous work we presented a long slit coronagraph (LSC), for which the presence of a slit in the coronagraphic focal plane induces a complex distribution of energy in the Lyot pupil-plane that cannot be easily masked with a binary Lyot stop. To alleviate this concern, we propose to use a pupil apodization to suppress diffraction, creating an apodized long slit coronagraph (ALSC). After describing how the apodization is optimized, we demonstrate its advantages with respect to the CLC in the context of SPHERE/IRDIS long slit spectroscopy (LSS) mode at low-resolution with a 0.12" slit and 0.18" coronagraphic mask. We perform different sets of simulations with and without aberrations, and with and without a slit to demonstrate that the apodization is a more appropriate concept for LSS, at the expense of a significantly reduced throughput (37%) compared to the LSC. Then we perform detailed end-to-end simulations of the LSC and the ALSC that include realistic levels of aberrations to obtain datasets representing 1h of integration time on stars of spectral types A0 to M0 located at 10 pc. We insert spectra of planetary companions at different effective temperatures (Teff) and surface gravities (log g) into the data at angular separations of 0.3" to 1.5" and with contrast ratios from 6 to 18 mag. Using the SD method to subtract the speckles, we show that the ALSC brings a gain in sensitivity of up to 3 mag at 0.3" with respect to the LSC, which leads to a much better spectral extraction below 0.5". In terms of Teff, we demonstrate that at small angular separations the limit with the ALSC is always lower by at least 100K, inducing an increase of sensitivity of a factor up to 1.8 in objects' masses at young ages.

Subjects: speech pathology, graduate school, admission, underrepresented, recruitment, community cultural wealth

description: Less than ten percent of speech-language pathologists (SLPs) are non-White despite the significant and growing population of racially marginalized people in the United States. With the demand for SLPs increasing, there is a need to facilitate access to the profession. The present study used the asset-based Community Cultural Wealth framework to analyze longitudinal survey data from a series of open-ended questions to investigate the sources of cultural capital that underrepresented students leverage to navigate the graduate school application process to master’s level speech pathology programs. Findings indicated that students developed a wide network and reflected on personal social injustices to facilitate the knowledge and self-efficacy needed to navigate the application process. These processes activated and cultivated the several interrelated forms of community cultural wealth underrepresented students relied on. This research identified several programs and resources which have been beneficial for applicants, directing universities to potential funding areas to demystify the application process for underrepresented students and increasing diversity in the speech language pathology workforce. Programs such as ASHA STEP Mentoring and student support groups are useful in fostering social, navigational, familial, and aspirational capital.

A defence of the truth norm of belief

Year: 2022
Subjects: subject: BD215.W4
subject: Belief and doubt
subject: Truth

description: For belief, the standard of correctness is truth. Truth is said to be the norm of belief. This thesis aims to address some recent challenges relating to various aspects of the truth norm of belief on a reason-based normative framework. On a reason-based normative framework, normativity is a matter of (normative) reasons. Reasons are facts that count in favour of a response, grounded in value-based, desire-based, constitutive, or practice-based facts. Reasons are the sort of things that we can respond to and they have weights in making a claim on us when we stand in a relation to them. Three anti-normativist challenges arise in recent discussion. First, the grounding challenge concerns whether the reason to believe truly (correctly) and to refrain from believing falsely (incorrectly) can be properly grounded. Second, the guidance challenge concerns whether the reason to believe truly and to refrain from believing falsely is something we can respond to in our belief-formation. Third, the weighting challenge concerns whether the reason to believe truly and to refrain from believing falsely has any weight in making a claim on us regarding what we ought to/may believe. In this thesis, I offer novel responses to all three challenges. I develop and defend a practice-based, variantist account of the truth norm, according to which, the truth norm of belief is grounded in a justified social practice, guides our belief-formation on a reason- responsive model of epistemic guidance, and makes varying claims on us regarding what we ought to/may believe depending on the circumstances.

Year: 2017
Subjects: education, didactics, virtual reality, augmented reality

description: Education in general participates in globally occurring medial transformation processes. Religious Education and Didactics, like all other academic disciplines, are challenged to conceptualize and reflect the integration of digitally-networked media in theory and practice. This should happen in at least three dimensions: in learning with digital media, in learning about digital media, and in the development and practice of a constructive/critical media education. The project is dedicated to the development, testing, and evaluation of learning scenarios in Religious Education classwork, and also to facilitating an exchange with sites of religious education beyond the school context.
Apart from didactic and discipline-specific approaches, this paper will show two
possible sequences: First, virtual realities (VR) augmented by representations of physical reality, thus enabling virtual expeditions, and second, physical realities augmented by virtual overlays (AR), creating experiential spaces in existing locations or new, non-location-bound, learning sites.

description: Changes in the domain or simple bug corrections lead to software updating. In general, software updating involves halting the running program, which is not desirable in the current applications, for reasons such as costs in business or undesired situations in mission-critical applications. To avoid program halting and to replace the current program version while running, many different Dynamic Software Updating (DSU) solutions have been developed. This paper presents a set of challenges in the existing research of dynamic software updating and the ideas for further developments.

The Role of Self-Esteem in the Academic Performance of Foster Youth in Higher Education
Creators: name: Viramontes, Audrey L.
Publisher: name: Zenodo
Year: 2023
Subjects: Foster Youth, Higher Education, Self-Esteem, College, Academic Performance

description: An overwhelming majority of current and former foster youth have a desire to obtain a college degree, however, less than 10% successfully earn a baccalaureate degree. To improve educational outcomes for foster youth students, it is crucial to understand how psychological factors affect their academic success. The purpose of this research is to explore the relationship between self-esteem and the academic achievement of foster youth in higher education. It is hypothesized that higher levels of self-esteem will correlate with increased grade point averages among foster youth students. This study is a secondary data analysis of the Foster Youth in Higher Education Study. In the current study, 101 participants were interviewed following completion of their second academic year at a 4-year university. Data related to grade point averages, number of courses passed and failed in the past year, and perceived self-esteem were collected. A significant positive correlation between self-esteem and grade point average was found. Multiple linear regression indicated self-esteem to be a significant predictor of increased grade point average among foster youth students attending a 4-year university. This research will have implications for foster youth students attending a post-secondary institution, as well as campus support services providers and administrators.

description: We substantially update the capabilities of the open source software package Modules for Experiments in Stellar Astrophysics (MESA), and its one-dimensional stellar evolution module, MESA Star. Improvements in MESA Star's ability to model the evolution of giant planets now extends its applicability down to masses as low as one-tenth that of Jupiter. The dramatic improvement in asteroseismology enabled by the space-based Kepler and CoRoT missions motivates our full coupling of the ADIPLS adiabatic pulsation code with MESA Star. This also motivates a numerical recasting of the Ledoux criterion that is more easily implemented when many nuclei are present at non-negligible abundances. This impacts the way in which MESA Star calculates semi-convective and thermohaline mixing. We exhibit the evolution of 3-8 Msun stars through the end of core He burning, the onset of He thermal pulses, and arrival on the white dwarf cooling sequence. We implement diffusion of angular momentum and chemical abundances that enable calculations of rotating-star models, which we compare thoroughly with earlier work. We introduce a new treatment of radiation-dominated envelopes that allows the uninterrupted evolution of massive stars to core collapse. This enables the generation of new sets of supernovae, long gamma-ray burst, and pair-instability progenitor models. We substantially modify the way in which MESA Star solves the fully coupled stellar structure and composition equations, and we show how this has improved MESA's performance scaling on multi-core processors. Updates to the modules for equation of state, opacity, nuclear reaction rates, and atmospheric boundary conditions are also provided. We describe the MESA Software Development Kit (SDK) that packages all the required components needed to form a unified and maintained build environment for MESA. [Abridged]

A five dimensional model with a fifth dimension as fundamental as time in terms of a cosmological approach

description: In five dimensional cosmological models, the convention is to include the fifth dimension in a way similar to the other space dimensions. In this work we attempt to introduce the fifth dimension in a way that a time dimension would be introduced. With such an internal space, we are able to obtain accelerated expansion without introducing dark energy. We obtain a five dimensional flat, meaning both Ricci flat and conformally flat, spacetime into which all relevant four dimensional cosmologies can be locally embedded. We also argue on the choice of the cosmological frame. The choice that is simplest and most convenient in terms of dimensional analysis, amounts to a linearly expanding universe.

title: GPU-Accelerated Demodulation for a Satellite Ground Station
Creators: name: Young, Emily Clark
Publisher: name: Utah State University
Year: 2019

description: One consequence of the increasing number of small satellite missions is an increasing demand for high data rate downlinks. As the satellites transmit at high data rates, ground-side receivers need to demodulate the transmitted data as quickly as possible. While application specific hardware can be designed, software defined radio solutions for ground stations are attractive for their flexibility, adaptability, and portability.
Another industry trend is the increasing use of Graphics Processing Units (GPUs) in general-purpose processing. By performing many operations simultaneously, GPUs are capable of accelerating processing when given a problem that can be implemented in a parallel manner. Furthermore, once a parallel algorithm is implemented, further speedups are possible by increasing hardware resources without need for any revision in the algorithm.
This project combines the above ideas by implementing a software defined radio algorithm to quickly demodulate high-speed data on a GPU. It demonstrates the viability of the GPU in software defined radio applications and particularly in the area of fast demodulation.
title: Activity Tracker Measurement of Physical Activity and Sedentary Time in the Workplace Including an Intervention Involving Reminders to Move
Creators: name: Dance, Cassie
Publisher: name: Utah State University
Year: 2019

description: Sedentary time and physical inactivity have negative impacts on health and health costs as well as an impact on workplace wellbeing. There is evidence that people are more sedentary and engage in less physical activity on work days. Additionally, sedentary behavior has been found to increase distress and negative mood. Activity trackers such as Fitbits are a useful way to collect and intervene on sedentary behavior and potentially impact other factors of workplace wellbeing in real time and promote self-monitoring. The reminder to move prompts that are now part of Fitbit models provide an innovative and simple way to intervene on workplace sedentary behavior with hourly movement prompts.
This study examined the impact of an intervention on sedentary time at work with Fitbit reminders to move and what impact the intervention had on other factors of workplace wellbeing including depression, positive and negative affect, job stress, and productivity. Participants were university employees who wore a Fitbit device for three weeks and completed pre-and post-study measures. For the first week, the Fitbit displayed only the watch screen with no access to other data. This was done to establish baseline data. For the second week, the Fitbit device and Fitbit app allowed for self-monitoring by displaying the activity being tracked, including steps, distance, calories expenditure, and stairs walked. For the third week, the sedentary time reduction was implemented by activating the Fitbit application reminder to move. This caused the Fitbit to vibrate at the 50-minute mark of the hour if the participant had not moved 250 steps in that time. Results show that having the reminders to move prompt activated decreased sedentary time at work and increased steps throughout the day on work days. These changes in sedentary time significantly contributed to decreases in depression. From the start of the study to after the intervention, on average participants reported significantly less depression, negative affect, and stress and more positive affect, affect balance, social functioning, physical functioning, and productivity at work. The benefits of in the moment self-monitoring and an intervention around sedentary time with Fitbits on factors of workplace wellbeing are discussed as well as limitations, and future directions.

description: A topology-intrinsic connection between the stabilities of Fermi surfaces (FSs) and topological insulators/superconductors (TIs/TSCs) is revealed. In particular, a one-to-one relation between the topological types of FSs and TIs/TSCs is rigorously derived; combining it with a well-established topological theory of FSs, we produce a complete table illustrating precisely topological types of all TIs/TSCs, while a valid part of it was postulated before. Moreover, we propose and prove a general index theorem that relates the topological charge of FSs on the natural boundary of a strong TI/TSC to its bulk topological number. Implications of the general index theorem on the boundary quasi-particles are also addressed.

description: The aim of this note is to investigate the open-open game of uncountable length. We introduce a cardinal number $μ(X)$, which says how long the Player I has to play to ensure a victory. It is proved that $\su(X)\leqμ(X)\leq\su(X)^+$. We also introduce the class $\mathcal C_κ$ of topological spaces that can be represented as the inverse limit of $κ$-complete system $\{X_σ,π^σ_ρ,Σ\}$ with $\w(X_σ)\leqκ$ and skeletal bonding maps. It is shown that product of spaces which belong to $\mathcal C_κ$ also belongs to this class and $μ(X)\leqκ$ whenever $X\in\mathcal C_κ$ .

description: BCK-sequences and n-commutative BCK-algebras were introduced by T. Traczyk, together with two related problems. The first one, whether BCK-sequences are always prolongable. The second one, if the class of all n-commutative BCK-algebras is characterised by one identity. W. A. Dudek proved that the answer to the former question is positive in some special cases, e.g. when BCK-algebra is linearly ordered. T. Traczyk showed that the answer to the latter is affirmative for n = 1, 2. Nonetheless, by providing counterexamples, we proved that the answers to both those open problems are negative.

description: We report the observation of a stepwise "melting" of the low-temperature Na-vacancy order in the layered transition metal oxide Na0.7CoO2. High-resolution neutron powder diffraction indicates the existence of two first-order structural transitions, one at T1 = 290 K, followed by a second at T2 = 400 K. Detailed analysis reveals that both transitions are linked to changes in the Na mobility. Our data are consistent with a two-step disappearance of Na-vacancy order through the successive opening of first quasi-1D (T1 > T > T2) and then 2D (T > T2) Na diffusion paths. These results shed new light on previous, seemingly incompatible, experimental interpretations regarding the relationship between Na-vacancy order and Na dynamics in this material. They also represent an important step towards the tuning of physical properties and the design of tailored functional materials through an improved control and understanding of ionic diffusion.

title: Rural Aging: The Geographic Reach of Service Access in Utah, Identifying Barriers and Solutions
Creators: name: Schiwal, Alexandra T.
Publisher: name: Utah State University
Year: 2019

description: This dissertation includes two studies of rural age-related services in the state of Utah. The first study combines geospatial, demographic data (number of people over 55) and age-related services (hospitals, hospice providers, nursing homes, senior centers, and Areas Agencies on Aging) at the county level and census-tract level to determine localized differences in proportional access to age-related services. Higher and lower proportions are then predicted by contextual factors including rural/urban gradient, economic industry, and broadband access. Results demonstrate that broadband access was significantly associated with higher access to age-related services, but being a retirement destination (increase in people over 65 in county from 2000-2010) was associated with lower spatial access to age-related services. The second study involved in-depth interviews with stakeholders from communities across Utah, and qualitative analysis to identify specific barriers to age-related service access in their communities. This approach generated knowledge about challenges to accessing services and stakeholder-supported starting points and solutions for overcoming some of the identified barriers to age-related services in these communities. Taken together, the spatial data and responses from persons living and serving older adults in rural communities complement an understanding of facilitators and barriers to service access, paired with solutions.
title: Public Transportation Accessibility: Perceptions of Riders with Disabilities in Utah

description: Transportation plays an essential role in social inclusion and participation, subjective well-being, and overall quality of life. A lack of private transportation options may make individuals with disabilities more dependent on public transportation systems. Despite increased use, people with disabilities continue to report barriers accessing public transportation services. Interestingly, little is known about these barriers at the regional transportation district level. The purpose of this study was to better understand the barriers and perceived accessibility of the Utah Transit Authority’s (UTA) public transportation system for individuals with disabilities living within the UTA service area.
Using an online survey, data were collected from 327 individuals with disabilities, family members of individuals with disabilities, or others who work with individuals with disabilities. This study found that individuals with disabilities generally have neutral to somewhat positive (accessible) views of UTA’s transportation services though there are differences based on disability type, modes of services used in general and specifically regarding fixed route service modes, and frequency of ridership are considered; that despite these neutral to somewhat accessible perceptions, barriers to accessing UTA’s fixed route and paratransit services exist, though there are differences based on disability type, modes of fixed route services used, and ridership frequency; and local and national policy changes may be necessary to resolve these barriers. The findings of this study have implications for UTA, other regional transportation districts, local and national transportation policy stakeholders, and the research community. For example, additional research is necessary to fully understand the specific system components which make UTA’s public transportation more accessible than has been indicated in previous studies, including an understanding of how these accessible practices could be generalized to other public transportation providers. Findings from future research could, in turn, be used to improve access to public transportation for individuals with disabilities. It is recognized that this study’s focus on electronic data collection and the potential influence of small subsamples underscores the need for additional research on the topics of perceived accessibility of public transportation and barriers to using public transportation services for individuals with disabilities.
title: Physical Factors Influencing Survival to Emergence and Time of Emergence of Shoreslope-Spawned Kokanee Salmon in Flaming Gorge Reservoir, Utah-Wyoming
Creators: name: Jeric, Randall J.
Publisher: name: Utah State University
Year: 1996

description: I used incubation baskets containing viable eggs and spawning substrate to estimate the survival to emergence and time of emergence of kokanee salmon Oncorhynchus nerka at depths to 20 m in Flaming Gorge Reservoir, Utah-Wyoming. Traps on the incubation baskets captured fry emerging from a known quantity of eggs. Water drawn into a syringe from an intragravel pipe buried near each incubation basket was used to determine intragravel dissolved oxygen concentrations throughout the intragravel period. Water from control baskets without eggs did not have significantly greater dissolved oxygen concentrations than adjacent water. A jar associated with each incubation basket collected sediment to determine absolute and organic sedimentation during the study. Temperatures at the substrate water interface were used to describe degree-days accumulated before emergence. Survival to emergence ranged from zero to 66% and was most significantly related to mean intragravel dissolved oxygen concentrations. Survival to emergence, mean intragravel dissolved oxygen concentrations , and organic sedimentation decreased with depth.
title: The Processes of Collective Buy-In, Actuation, and Deep Social Learning in Seminary Classes
Creators: name: Anderson, Donald B.
Publisher: name: Utah State University
Year: 2019

description: This phenomenological study explored a common essence of collective class actuation (CCA) among six seminary teachers in a Western state. CCA is an optimal learning state of a class collective. Data were gathered through interviews, observations, and a focus group. Data analysis yielded themes, textural and structural descriptions, an overall essence, and a model explaining the processes of buy-in and actuation.
Findings indicate that seminary teachers seek to actuate their classes by leading them toward agentic, collective buy-in. This requires management of two social environments: the internal social environment (the heart) and the external social environment. The internal social environment is comprised of a sense of collective relevancy and a sense of collective trust. If both of these collective beliefs are present, students may be more likely to buy into the purpose and activity of the class collective. The external social environment relates to classroom sociality, which can be too high (hypersocial) for learning, or too low (hyposocial) for learning. These teachers therefore describe seeking to keep their classes in the sweet zone of learning by simultaneously maintaining high engagement and high focus. Both social environments (internal and external) affect one another and influence buy-in and actuation for deep learning. Participants manage the complexities of both environments by maintaining a splendid mix of learning and enjoyment, thereby generating an optimal learning experience.

description: We point out that stars in the mass window ~ 8-12 Msun can serve as sensitive probes of the axion-photon interaction, g_{Aγγ}. Specifically, for these stars axion energy losses from the helium-burning core would shorten and eventually eliminate the blue loop phase of the evolution. This would contradict observational data, since the blue loops are required, e.g., to account for the existence of Cepheid stars. Using the MESA stellar evolution code, modified to include the extra cooling, we conservatively find g_{Aγγ}

description: In this paper we derive time reversal imaging functionals for two strongly causal acoustic attenuation models, which have been proposed recently. The time reversal techniques are based on recently proposed ideas of Ammari et al for the thermo-viscous wave equation. Here and there an asymptotic analysis provides reconstruction functionals from first order corrections for the attenuating effect. In addition, we present a novel approach for higher order corrections.

description: We compute the proper time Lyapunov exponent for charged Myers Perry black hole spacetime and investigate the instability of the equatorial circular geodesics (both timelike and null) via this exponent. We also show that for more than four spacetime dimensions $(N \geq 3)$, there are \emph{no} Innermost Stable Circular Orbits (ISCOs) in charged Myers Perry black hole spacetime. We further show that among all possible circular orbits, timelike circular orbits have \emph{longer} orbital periods than null circular orbits (photon spheres) as measured by asymptotic observers. Thus, timelike circular orbits provide the \emph{slowest way} to orbit around the charged Myers Perry black hole.
