title: Coaching A Second Language
Creators: name: Hatch, Kyle Asa
Publisher: name: Utah State University
Year: 2014

description: In this portfolio the author expresses his views of successful second language teaching. The author’s beliefs are centered on the teacher’s responsibility to provide an atmosphere in which students are presented material in an effective way, to offer students opportunities to engage with the language, and to understand the learners’ unique needs and interests. Also included in the portfolio are three artifacts which illustrate various teaching strategies the author has used to help create this atmosphere. The Culture Artifact explains the use of multimedia authentic texts to teach language and culture. The Language Artifact gives examples of how I have used sociocultural theory to teach abstract concepts, such as reflexive verbs and formal and informal pronoun use in an L2 class. The Literacy Artifact describes a proposed study to research how graphic novels impact internalization of the L2 in a Spanish as a foreign language class. The annotated bibliography covers the topics of culture, motivation, and feedback, which are running themes throughout the portfolio
Adsorption properties and third sound propagation in superfluid $^4$He films on carbon nanotubes

description: We consider the adsorption properties of superfluid $^4$He films on carbon nanotubes. One major factor in the adsorption is the surface tension force arising from the very small diameter of the nanotubes. Calculations show that surface tension keeps the film thickness on the tubes very thin even when the helium vapor is increased to the saturated pressure. The weakened Van der Waals force due to the cylindrical geometry also contributes to this. Both of these effects act to lower the predicted velocity of third sound propagation along the tubes. It does not appear that superfluidity will be possible on single-walled nanotubes of diameter about one nm, since the film thickness is less than 3 atomic layers even at saturation. Superfluidity is possible on larger-diameter nanotube bundles and multi-walled nanotubes, however. We have observed third sound signals on nanotube bundles of average diameter 5 nm which are sprayed onto a Plexiglass surface, forming a network of tubes.

title: Blackface Shakespeare: Racial and Gender Anxiety on the American Stage
Creators: name: Hutchings, Kristen
Publisher: name: Utah State University
Year: 2014

description: Early scholars of blackface minstrelsy have often over-simplified and rebuked nineteenth-century American Negro minstrel shows for their racially barbed gibes at African Americans. Though it recognizes minstrelsy’s blatant racism against the newly freed slaves of the 1860s, this study agrees with many modern scholars in recognizing deeper cultural themes Negro minstrels highlighted onstage during the years surrounding the Civil War. The study focuses specifically on the rich literary contribution of two afterpieces (the final act of the minstrel show) burlesquing Shakespeare’s Othello: Desdemonum and Othello; A Burlesque. Using the racist jargon as a tool, this study examines how women and immigrants during the nineteenth century were able to identify and differentiate their identities with African Americans and find their place within American Society. Though women, African Americans, and the Irish were the three most hated and feared groups of the American White male, they also exemplified a unified power through their representation on the minstrel stage.

title: The Revolutionary Climate: Applying Theories of Revolution to Assess Political Stability in Contemporary Brazil
Creators: name: Nicholls, Arden Andrew
Publisher: name: Utah State University
Year: 2014

description: Rapid modernization has throughout history presented unique challenges for developing countries. Generally judged to be a good thing--but if too rapid--modernization can strain a government if that governmental system is unable to keep up. Historically concrete social classes begin to blur or shift as massive capital investments are injected--often unequally. Proliferation of the middle class is commonly seen as a country modernizes quickly; with the new middleclass comes rising expectations and modern demands on government. Social programs, infrastructure, political and social equality and general societal advancements are all expected to increase at roughly the same pace as the economy. Social strata may begin comparing their relative wellbeing to that of their regional or global counterparts; if perceived as being less well off, societal discontent is more likely (social media and the technology revolution have greatly facilitated this).

We use the entanglement measure proposed by us for $N$-qubit pure states (PRA \textbf{77}, 062334 (2008)). Our procedure reproduces the earlier results (PRL \textbf{87}, 137901 (2001)). The geometric method has the distinct advantage that it gives an experimental way to monitor the process of optimizing entanglement production.

description: Continuous gravitational waves are long-lasting forms of gravitational radiation produced by persistent quadrupolar variations of matter. Standard expected sources for ground-based interferometric detectors are neutron stars presenting non-axisymmetries such as crustal deformations, r-modes or free precession. More exotic sources could include decaying ultralight boson clouds around spinning black holes. A rich suite of data-analysis methods spanning a wide bracket of thresholds between sensitivity and computational efficiency has been developed during the last decades to search for these signals. In this work, we review the current state of searches for continuous gravitational waves using ground-based interferometer data, focusing on searches for unknown sources. These searches typically consist of a main stage followed by several post-processing steps to rule out outliers produced by detector noise. So far, no continuous gravitational wave signal has been confidently detected, although tighter upper limits are placed as detectors and search methods are further developed.

description: As a laboratory for loop quantum gravity, we consider the canonical quantization of the three-dimensional Chern-Simons theory on a noncompact space with the topology of a cylinder. Working within the loop quantization formalism, we define at the quantum level the constraints appearing in the canonical approach and completely solve them, thus constructing a gauge and diffeomorphism invariant physical Hilbert space for the theory. This space turns out to be infinite dimensional, but separable.

description: The precision measurements of the spectra of cosmic ray nuclei and leptons in recent years have revealed the existence of multiple features, such as the spectral break at $\sim 300$ GV rigidity seen by PAMELA and AMS-02 and more recently confirmed by DAMPE and CALET, the softening in the spectra of H and He nuclei at $\sim 10$ TV reported by DAMPE, confirming previous hints by NUCLEON and CREAM, a tiny change of slope at $\sim 40$ GeV in the electron spectrum, revealed by AMS-02, and the large spectral break at $\sim$ TeV reported by indirect (HESS, MAGIC and VERITAS) and direct (DAMPE, CALET) measurements of the total (electrons+positrons) lepton spectrum. In all these cases, the possibility has been suggested that these features might reflect the occasional presence of a local cosmic ray source, inducing a noticeable reshaping of the average expected spectra. All these proposals have to face the question of how likely it is for such a source to exist, a question that we address here in a quantitative way. We study the statistical properties of random distribution of sources in space and time, and the effect of the spiral structure of our Galaxy for both the spectra of light nuclei (p and He) and leptons (electrons and positrons) in different energy regions.

title: A Comparison of Four-Step Model and Path Flow Estimator for Forecasting Network Flow: A Case Study of Cache County in Utah
Creators: name: Pedaballi, Siddareddy B.
Publisher: name: Utah State University
Year: 2006

description: Development of alternative methodologies for travel demand modeling has become important in recent years due to the lack of resources for small and medium communities to adopt conventional four step travel models. Many researchers have proposed alternative tools of travel demand modeling for these communities. But majority of them still require large amount of data and technical sophistication.
In this study, the Path Flow Estimator (PFE) is used to estimate the network traffic of Cache County. PFE estimations are based on the collected traffic counts, vehicle production and attractions of zones estimated using Institute of Transportation Engineers (ITE) trip generation rates. The daily trips of the four step model are converted into peak hour trips using a common peak hour factor. The PFE estimations are then compared with the estimations of the four-step model.
The differences in vehicle trip production and attraction estimates by both models are due to the use of a common peak hour factor to reduce the daily trips of the four step model to peak hour trips. These differences got dis-aggregated spatially in the trip table estimations, leading to similar trip table estimations. The trip length frequency distributions of both models accounting for congestion have similar distribution. The average trip length estimated by PFE is 2.36 minutes more than the four-step model. Further, PFE has estimated link flows better than the four step model on the links having ground counts due the traffic counts constraint in PFE' s formulation. Low percentage root mean square errors between PFE and the four step model estimated link flows show that PFE has replicated the link flows satisfactorily. The four-step model has overestimated the link flows on Main Street due to the use of daily trips V-C ratio in the zones with high demand due to the slight overestimation of trips by ITE trip generation rates for those zones. On the screenlines identified in the original four step model also PFE has performed better than the four step model.
The results of this study show that Path Flow Estimator can be a useful tool in traffic demand modeling for small and medium communities. But PFE should not be used for large communities because of the difficulty in arriving proper trip generation rate for complex land uses. PFE does not distinguish between an internal zone and an external zone.
title: Pheasant Habitat Improvement Through Multiple Land Use Planning on Cache Valley Farmland
Creators: name: Heath, Shannon B.
Publisher: name: Utah State University
Year: 1984

description: In Utah, the number of farms has been steadily decreasing since the 1930's while farm size has grown and mechanization increased (Utah Agricultural Statistics, 1981). The "family farm" is beginning to disappear as larger farms become more economical (McCorkle, Jr., 1981). Due primarily to this trend toward more intensive land use, habitat for the ring-necked pheasant (Phasianus colchicus) is on the decline (Kellert, 1981). In addition, changes which have occurred in crop production since 1950 have not favored pheasant production (Nish, 1973). It is of critical importance that attention be drawn to the conservation of pheasant habitat if the future of this popular gamebird in Utah is to be secured.
Operator product expansion for B-meson distribution amplitude and dimension-5 HQET operators
Creators: name: Kawamura, Hiroyuki

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: When the bilocal heavy-quark effective theory (HQET) operator for the B-meson distribution amplitude has a light-like distance t between the quark and antiquark fields, the scale \sim 1/t separates the UV and IR regions, which induce the cusp singularity in radiative corrections and the mixing of multiparticle states in nonperturbative corrections, respectively. We treat these notorious UV and IR behaviors simultaneously using the operator product expansion, with the local operators of dimension $d \le 5$ and radiative corrections at order α_s for the corresponding Wilson coefficients. The result is derived in the coordinate space, which manifests the Wilson coefficients with Sudakov-type double logarithms and the higher-dimensional operators with additional gluons. This result yields the B-meson distribution amplitude for t less than \sim 1 GeV^{-1}, in terms of $\barΛ=m_B - m_b$ and the two additional HQET parameters as matrix elements of dimension-5 operators. The impact of these novel HQET parameters on the integral relevant to exclusive B decays, λ_B, is also discussed.

description: The distributions of the quark number and chiral condensate over the gauge fields are computed for QCD in Euclidean space at nonzero quark chemical potential. As both operators are non-hermitian the distributions are in the complex plane. Moreover, because of the sign problem, the distributions are not real and positive. The computations are carried out within leading order chiral perturbation theory and give a direct insight into the delicate cancellations that take place in contributions to the total baryon number and the chiral condensate.

title: Relations Between Teachers' Implicit Theories of Intelligence, Standardized Achievement Testing, and Classroom Goals
Creators: name: Ringle, Sydnie W.
Publisher: name: Utah State University
Year: 2014

description: An achievement gap between ethnic minorities and whites continues to exist within the US, as well as between the US and varying countries (Peterson, Woessmann, Hanushek, & Lastra-Anadon, 2011). Research has identified several factors that contribute to this gap, such as differences in curricula across countries, teacher quality, and school funding. In addition to these factors, teachers’ implicit theories of intelligence may also contribute to the achievement gap. Whether teachers view intelligence as fixed (entity theory) or malleable (incremental theory) can impact instructional practices, specifically the use of performance and learning goals. Performance goals focus on evaluation, ability, and performance rather than mastery of material, growth, and overall learning as seen in learning goals are (Dweck, 1999; Shim, Cho, & Cassady, 2013). Research is limited regarding the development of implicit theories of intelligence; however, there is evidence culture may be involved. Identifying specific cultural practices that influence the development of implicit theories of intelligence may provide a unique perspective on pedagogy and how teachers interact with students. This review of the literature discusses one cultural practice that may be related to the development of implicit theories of intelligence, mainly standardized achievement testing. First, this literature review defines the construct of implicit theories of intelligence; then, reviews the literature on performance and learning goals as mediating factors of implicit theories of intelligence, and, finally, explores the relation between these and standardized achievement testing. Areas for future research and implications are also discussed.

description: Ransomware has evolved from its inception with PC Cyborg, which encrypted files and demanded a ransom, to sophisticated threats employing advanced encryption and evasion techniques. This evolution has shifted the target from individual users to larger organisations, creating a multi-billion dollar industry. The exploitation of system vulnerabilities by ransomware highlights the importance of maintaining an up-to-date Common Vulnerabilities and Exposures (CVE) database. The project focuses on identifying ransomware infection factors, evaluating attack vectors, and implementing preventive measures. It also involves developing a local CVE database to filter for ransomware-related CVEs and an automated checklist to assess the presence of specific antiviruses, firewalls, and installed software versions. These efforts are designed to enhance the organisation's ability to detect and mitigate ransomware threats effectively.

description: Security has become paramount in modern software services as more and more security breaches emerge, impacting final users and organizations alike. Trends like the Microservice Architecture bring new security challenges related to communication, system design, development, and operation. The literature presents a plethora of security-related solutions for microservices-based systems, but the spread of information difficult practitioners' adoption of novel security related solutions. In this study, we aim to present a catalogue and discussion of security solutions based on algorithms, protocols, standards, or implementations; supporting principles or characteristics of information security, considering the three possible states of data, according to the McCumber Cube. Our research follows a Systematic Literature Review, synthesizing the results with a meta-aggregation process. We identified a total of 30 primary studies, yielding 75 security solutions for the communication of microservices.

description: This study was designed to determine whether mazing behavior in narrative retells of bilingual English and Spanish speaking children was affected by language, complexity of sentence structure, and language development over time. Language transcripts were analyzed from English and Spanish narrative retells elicited from 216 children between the ages of 5 and 9 at the beginning and end of kindergarten, first, and second grade years. Findings revealed a statistically significant difference in the average maze scores and sentence types. A significant interaction was also found between time and language, with maze scores remaining nearly level over time in English and decreasing slightly in Spanish.

description: We consider the mass-critical focusing nonlinear Schrodinger equation in the presence of an external potential, when the nonlinearity is inhomogeneous. We show that if the inhomogeneous factor in front of the nonlinearity is sufficiently flat at a critical point, then there exists a solution which blows up in finite time with the maximal (unstable) rate at this point. In the case where the critical point is a maximum, this solution has minimal mass among the blow-up solutions. As a corollary, we also obtain unstable blow-up solutions of the mass-critical Schrodinger equation on some surfaces. The proof is based on properties of the linearized operator around the ground state, and on a full use of the invariances of the equation with an homogeneous nonlinearity and no potential, via time-dependent modulations.

Instead of taking the operator directly from a model problem, it is constructed to be a best fit to the exact Hamiltonian within any desired functional form. When applied to many-body perturbation theory for electrons, strongly improved convergence is observed in cases where the conventional Fock hamiltonian leads to divergence or slow convergence.

Borel and Stokes Nonperturbative Phenomena in Topological String Theory and c=1 Matrix Models

description: We address the nonperturbative structure of topological strings and c=1 matrix models, focusing on understanding the nature of instanton effects alongside with exploring their relation to the large-order behavior of the 1/N expansion. We consider the Gaussian, Penner and Chern-Simons matrix models, together with their holographic duals, the c=1 minimal string at self-dual radius and topological string theory on the resolved conifold. We employ Borel analysis to obtain the exact all-loop multi-instanton corrections to the free energies of the aforementioned models, and show that the leading poles in the Borel plane control the large-order behavior of perturbation theory. We understand the nonperturbative effects in terms of the Schwinger effect and provide a semiclassical picture in terms of eigenvalue tunneling between critical points of the multi-sheeted matrix model effective potentials. In particular, we relate instantons to Stokes phenomena via a hyperasymptotic analysis, providing a smoothing of the nonperturbative ambiguity. Our predictions for the multi-instanton expansions are confirmed within the trans-series set-up, which in the double-scaling limit describes nonperturbative corrections to the Toda equation. Finally, we provide a spacetime realization of our nonperturbative corrections in terms of toric D-brane instantons which, in the double-scaling limit, precisely match D-instanton contributions to c=1 minimal strings.

description: Data from the LHC at 7, 8, and 13 TeV have so far yielded no evidence for new particles beyond the 125 GeV Higgs boson; in particular, there have been no signs of SUSY. However, the complementary nature of physics with $e^+e^-$ collisions still offers many interesting scenarios in which SUSY can be discovered at the ILC. These scenarios take advantage of the capability of $e^+e^-$ collisions to observe events with missing four-momentum -- a signature not available at hadron colliders, where only transverse imbalance is observable. Due to low backgrounds and trigger-less operation, detectors at $e^+e^-$ colliders can observe events with much less visible energy than what is possible at hadron colliders. In this contribution, we will present detailed simulation studies done with the ILD concept at the ILC. These studies include simulation of the full SM background, as well as realistic accelerator conditions. We will show results both on expected discovery and exclusion reaches for the most challenging SUSY channels, such as higgsinos or winos at low mass differences. Evaluations of precision of model-parameter measurements, in case of discovery, will also be given. We also report on how such measurements can be used to put constraints on parts of the sparticle-spectrum beyond direct reach, and to discriminate between different models of SUSY breaking at high scales.

description: Dark matter halos represent the highest density peaks in the matter distribution. Conversely, cosmic voids are under-dense patches of the universe. Probing the mass distribution of the universe requires various approaches, including weak gravitational lensing that subtly modifies the shape of distant sources, and Doppler lensing that changes the apparent size and magnitude of objects due to peculiar velocities. In this work, we adopt both gravitational and Doppler lensing effects to study the underlying matter distribution in and around cosmic voids/halos. We use the relativistic $N$-body code \texttt{gevolution}, to generate the mass perturbations and develop a new ray-tracing code that relies on the design of the ray bundle method. We consider three categories of halo masses and void radii, and extract the cosmological information by stacking weak-lensing and Doppler lensing signals around voids/halos. The results of this paper show that the most optimal strategy that combines both gravitational and Doppler lensing effects to map the mass distribution should focus on the redshift range $z\approx 0.3-0.4$. The recommendation of this paper is that future spectroscopic surveys should focus on these redshifts and utilise the gravitational and Doppler lensing techniques to extract information about underlying matter distribution across the cosmic web, especially inside cosmic voids. This could provide a complimentary cosmological analysis for ongoing or future low-redshift spectroscopic surveys.

An investigation of children’s arousal levels as they read graded materials

description: The major purpose of this study was to attempt to determine word recognition and comprehension criteria for the frustrational level of reading by means of the galvanic skin response (GSR), in order to substantiate the conventional criteria used by authorities in the field. The sample consisted of 60 children in grades two and three, for whom parental consent for inclusion in the study had been obtained. Scores from a standardized reading achievement test were used to stratify all second and third grade children on reading achievement level (below, average, and above average). Ten children for each grade and reading achievement level were then randomly selected (N=60). Subjects were required to read the words on the Wide Range Achievement Test-Level 1 (1965) while being monitored on the GSR in order to obtain an index of each child's high arousal level. This level was then to have been used to indicate the frustrational level of reading as the child read the passages of the Diagnostic Reading Scales (1972), that was treated as an informal reading inventory. At this level, word recognition and comprehension accuracy scores were to have been obtained, and these compared to the existing criteria. However, during the reading of the Diagnostic Reading Scales passages no subject attained the arousal level obtained on the Wide Range Achievement Test, and therefore frustrational level of reading had to be determined from the criteria stated in Johnson and Kress (1965). As a result, alternate hypotheses were postulated. GSR arousal levels were obtained for the instructional and pre- frustrational levels of reading, for both the oral reading and comprehension sections of the test, and these statistically compared. At the frustrational level of reading, comparisons were made between the oral reading and comprehension sections of the test, the three reading achievement groups, and for the boys and the girls. Data were analyzed using a two-way analysis of variance for a repeated measures design. It was found that there was no significant difference between the oral reading of the passage and the comprehension section at both the instructional and frustrational levels of reading. The three reading achievement levels did not differ significantly in arousal at the frustrational level of reading. Implications of the results were discussed.

description: It has been conjectured that four-dimensional N=8 supergravity may provide a suitable framework for a `Theory of Everything', if its composite SU(8) gauge fields become dynamical. We point out that supersymmetric three-dimensional coset field theories motivated by lattice models provide toy laboratories for aspects of this conjecture. They feature dynamical composite supermultiplets made of constituent holons and spinons. We show how these models may be extended to include N=1 and N=2 supersymmetry, enabling dynamical conjectures to be verified more rigorously. We point out some special features of these three-dimensional models, and mention open questions about their relevance to the dynamics of N=8 supergravity.

description: We present an analytic study of the density fluctuation of a Newtonian self-gravity fluid in the expanding universe with $Ω_Λ+Ω_m=1$, which extends our previous work in the static case. By use of field theory techniques, we obtain the nonlinear, hyperbolic equation of 2-pt correlation function $ξ$ of perturbation. Under the Zel'dolvich approximation the equation becomes an integro-differential equation and contains also the 3-pt and 4-pt correlation functions. By adopting the Groth-Peebles and Fry-Peebles ansatz, the equation becomes closed, contains a pressure term and a delta source term which were neglected in Davis and Peebles' milestone work. The equation has three parameters of fluid: the particle mass $m$ in the source, the overdensity $γ$, and the sound speed $c_s$. We solve only the linear equation and apply to the system of galaxies. We assume two models of $c_s$ and, take an initial power spectrum at a redshift $z=7$, which inherits the relevant imprint from the spectrum of baryon acoustic oscillations at the decoupling. The solution $ξ({\bf r}, z)$ is growing during expansion, and contains $100$Mpc periodic bumps at large scales, and a main mountain (a global maximum with $ξ\propto r^{-1}$) at small scales $r\lesssim 50$Mpc. The profile of $ξ$ agrees with the observed ones from galaxy and quasar surveys. The bump separation is given by the Jeans length $λ_J$ as the correlation scale, also modified by $γ$ and $c_s$. The main mountain is largely generated by the source $\propto m$ as the clustering scale. Since the outcome is affected by the initial condition and the parameters as well, it is hard to infer the imprint of baryon acoustic oscillations accurately. The difficulties with the sound horizon as a distance ruler are pointed out.

description: We report experimental determination of the phase-matching function for type-II three-wave mixing in a periodically poled KTiOPO_4 waveguide in the 792-815 nm spectral region. The measurement was performed by sum-frequency generation of spectrally tuned fundamental components. Strong dependence of the observed signal on the excited spatial modes in the waveguide has been observed and fully interpreted. These results indicate a route to employ the waveguide for spontaneous parametric down-conversion producing photon pairs in well-defined spatial modes.

description: We investigate the efficiency of atom-cavity based photon-generation schemes to deliver single photons of arbitrary temporal shape. Our model applies to Raman transitions in three-level atoms with one branch of the transition driven by a laser pulse, and the other coupled to a cavity mode. For any possible shape of the single-photon wavepacket, we derive an unambiguous analytic expression for the shape of the required driving laser pulse. We furthermore discuss the constraints limiting the maximum probability for emitting any desired photon, and use these to estimate upper bounds for the efficiency of the process. The model is not only valid for Vacuum-Stimulated Raman Adiabatic Passages (V-STIRAP) in the strong-coupling and bad-cavity regime, but it generally allows controlling the coherence and population flow in any Raman process.

description: Many extensions of the standard model predict the existence of hidden sectors that may contain unbroken abelian gauge groups. We argue that in the presence of quantum decoherence photons may convert into hidden photons on sufficiently long time scales and show that this effect is strongly constrained by CMB and supernova data. In particular, Planck-scale suppressed decoherence scales D ~ E^2/M_Pl (characteristic for non-critical string theories) are incompatible with the presence of even a single hidden U(1). The corresponding bounds on the decoherence scale are four orders of magnitude stronger than analogous bounds derived from solar and reactor neutrino data and complement other bounds derived from atmospheric neutrino data.

Temporal Difference Updating without a Learning Rate

description: We derive an equation for temporal difference learning from statistical principles. Specifically, we start with the variational principle and then bootstrap to produce an updating rule for discounted state value estimates. The resulting equation is similar to the standard equation for temporal difference learning with eligibility traces, so called TD(lambda), however it lacks the parameter alpha that specifies the learning rate. In the place of this free parameter there is now an equation for the learning rate that is specific to each state transition. We experimentally test this new learning rule against TD(lambda) and find that it offers superior performance in various settings. Finally, we make some preliminary investigations into how to extend our new temporal difference algorithm to reinforcement learning. To do this we combine our update equation with both Watkins' Q(lambda) and Sarsa(lambda) and find that it again offers superior performance without a learning rate parameter.

description: Motivated by the study of Weyl structures on conformal manifolds admitting parallel weightless forms, we define the notion of conformal product of conformal structures and study its basic properties. We obtain a classification of Weyl manifolds carrying parallel forms, and we use it to investigate the holonomy of the adapted Weyl connection on conformal products. As an application we describe a new class of Einstein-Weyl manifolds of dimension 4.
