description: The purpose of the study was to investigate the effects of a two and one-half day faculty training workshop designed to promote sex equitable and effective teacher-student interactions at a postsecondary institution for hearing-impaired students. The major research questions asked: (1) Do the relative percentages of teacher feedback categorized as praise, acceptance, remediation and criticism distributed by professors significantly change following training? (2) Are teacher-student interactions more equitably distributed between male and female students following training? (3) Do professors distribute praise, acceptance, remediation and criticism comments more equitably to male and female hearing-impaired students following training? Additional research questions pertain to student participation and the differences between male and female professors' distribution of feedback. Data were obtained from a sample of twenty Gallaudet College professors (collected during two consecutive semesters). Professors were observed teaching three times during the fall semester (pre-observation), then, after participating in the training workshop were observed three additional times for comparison (post-observation). Observers were trained to code classroom interactions using the INTERSECT Observation Instrument. Observers maintained an interrater reliability of .85 or higher. Analysis of variance with repeated measurements was the statistical procedure used. The Tukey HSD test was also used to compare individual mean scores as a follow-up procedure to each of the analyses. Post-observation findings reflected a significant decrease in the relative percentage of non-specific teacher feedback categorized as accept. Professors also distributed praise comments more equitably to female students. Additionally, a 40 percent increase in the frequency of professor-student interactions was observed. During pre- and post-observation it was noted that the percent of students who did not participate during class time was significantly higher in male taught classes than in female taught classes. Results suggested that training to promote equitable and effective teacher-student interactions may be a successful means to reducing bias in classes for hearing-impaired students. Following awareness activities and skill development, both hearing and hearing-impaired professors tended to encourage student participation with greater frequency, praise students more equitably and increase the precision of their reactions to student responses.

description: The conductance quantization and shot noise below the first conductance plateau $G_0 = 2e^2/h$ are measured in a quantum point contact fabricated in a GaAs/AlGaAs tunnel-coupled double quantum well. From the conductance measurement, we observe a clear quantized conductance plateau at $0.5G_0$ and a small minimum in the transconductance at $0.7 G_0$. Spectroscopic transconductance measurement reveals three maxima inside the first diamond, thus suggesting three minima in the dispersion relation for electric subbands. Shot noise measurement shows that the Fano factor behavior is consistent with this observation. We propose a model that relates these features to a wavenumber directional split subband due to a strong Rashba spin--orbit interaction that is induced by the center barrier potential gradient of the double-layer sample.

We have found significant deviations from the expected Poissonian statistics for the ILC and the foregrounds phases. Our analysis shows that the low multipole range of the ILC power spectrum contains some of the foregrounds residues.

description: To discuss one-photon polarization states we find an explicit form of the Wigner's little group element in the massless case for arbitrary Lorentz transformation. As is well known, when analyzing the transformation properties of the physical states, only the value of the phase factor is relevant. We show that this phase factor depends only on the direction of the momentum $\vec{k}/|\vec{k}|$ and does not depend on the frequency $k^0$. Finally, we use this observation to discuss the transformation properties of the linearly polarized photons and the corresponding reduced density matrix. We find that they transform properly under Lorentz group.

description: A one-dimensional cluster model with next-nearest-neighbor interactions and two additional composite interactions is solved; the free energy is obtained and a correlation function is derived exactly. The model is diagonalized by a transformation obtained automatically from its interactions, which is an algebraic generalization of the Jordan-Wigner transformation. The gapless condition is expressed as a condition on the roots of a cubic equation, and the phase diagram is obtained exactly. We find that the distribution of roots for this algebraic equation determines the existence of long-range order, and we again obtain the ground-state phase diagram. We also derive the central charges of the corresponding conformal field theory. Finally, we note that our results are universally valid for an infinite number of solvable spin chains whose interactions obey the same algebraic relations.

A STUDY OF THE FREE ENERGY OF THE LENZ-ISING MODEL USING THE CLUSTER VARIATION METHOD OF MORITA (CRITICAL POINT, COOPERATIVE PHENOMENA, CURIE TEMPERATURE, CHAOS)
Creators: name: Condon, John Joseph
Publisher: name: American University
Year: 2023

description: The Cluster Variation Method proposed by Morita is shown to yield a development of the entropy into an alternating series when applied to the Lenz-Ising model. Truncation of this series to its first N terms gives an N-th order variationally based approximation to the exact statistical behavior of this system. The first four orders of this sequence of approximations have been carried out in this work. The first level of approximation reproduces the familiar mean field results; among these results is a second order phase transition for all lattices of all dimensions. The second level reproduces the familiar Bethe-Peierls approximation; there is no phase transition in one dimension, while a second order phase transitions is found in every lattice of higher dimensions. Many researchers have studied higher order approximations, usually finding curious behaviors such as complex Curie temperatures. This work shows that such behavior is due to the alternating sign of the terms in the entropy expansion. The effect is large enough to cause a non-physical global minimum to appear on the boundary of the variation space, starting with the third order approximation. Even in the second approximation, the entropy becomes negative for certain regions of the variation space, which is certainly unphysical. A modification of the Cluster Variation Method suggested by common practices in numerical methods is effective in suppressing these undesired effects. The (2n + 1)-cluster results are then an improvement over those of the (2n)-cluster approximation. The (2n)-cluster results are less affected by spurious minima.

Chandra and XMM-Newton Observations of the Double Cluster Abell 1758

description: Abell 1758 was classified as a single rich cluster of galaxies by Abell, but a ROSAT observation showed that this system consists of two distinct clusters (A1758N and A1758S) separated by approximately $8\arcmin$ (a projected separation of 2 Mpc in the rest frame of the clusters). Only a few galaxy redshifts have been published for these two clusters, but the redshift of the Fe lines in the Chandra and XMM-Newton spectra shows that the recessional velocities of A1758N and A1758S are within 2,100 km s$^{-1}$. Thus, these two clusters most likely form a gravitationally bound system, but our imaging and spectroscopic analyses of the X-ray data do not reveal any sign of interaction between the two clusters. The Chandra and XMM-Newton observations show that A1758N and A1758S are both undergoing major mergers. A1758N is in the late stages of a large impact parameter merger between two 7 keV clusters. The two remnant cores have a projected separation of 800 kpc. Based on the measured pressure jumps preceding the two cores, they are receding from one another at less than 1,600 km s$^{-1}$. The two cores are surrounded by hotter gas ($\mathrm{kT}=9$--12 keV) that was probably shock heated during the early stages of the merger. The gas entropy in the two remnant cores is comparable with the central entropy observed in dynamically relaxed clusters, indicating that the merger-induced shocks stalled as they tried to penetrate the high pressure cores of the two merging systems.Each core also has a wake of low entropy gas indicating that this gas was ram pressure stripped without being strongly shocked (abridged).

description: Background: Adverse childhood experiences (ACEs) are stressful or traumatic events experienced in childhood and are related to the development of a broad range of health problems throughout a person's lifespan. Reporting four or more ACEs is strongly associated with adult health and social problems, however, there is a lack of research studying individuals ability to overcome ACEs and achieve successful outcomes. The purpose of this study was to examine the proportion of individuals who reported four or more ACEs who attained 'successful' health and economic outcomes as adults.Methods: Data were obtained from the Centers' for Disease Control and Prevention's 2011-2012 Behavioral Risk Factor Surveillance System (BRFSS) from nine states with respondents to the ACEs question module (N=86,968), and were presented as weighted estimates to be representative of the approximate 32 million adult state residents. 'Successful' adult health was defined as excellent, very good, or good self-reported health and economic 'success' was defined as being in the upper 50% of household income in an age group. The likelihood of health and economic 'success' across four categories of reported ACEs are reported.Results: Comparing respondents who reported zero ACEs to those reporting four or more, 93.5% versus 84.1% of age 18-34 attained successful health outcomes, respectively, and 56.3% versus 44.9% attained successful economic outcomes. Of respondents age 35-54, 86.3% and 49.7% with an ACE count of zero attained successful health and successful economic outcomes, respectively, compared to 74.5% and 38.2% of respondents with an ACE count of four or more. Among respondents age 55 and over, 77.0% and 58.5% with an ACE count of zero attainedsuccessful health and successful economic outcomes, respectively, compared to 64.9% and 59.2% of respondents with an ACE count of four or more, all comparisons p <0.001.Conclusion: Study findings indicate those with four or more ACEs attain significantly fewer 'successful' health and economic outcomes compared to those with zero ACEs, however, a majority of those with high ACE counts were successful under the definitions used in the study. More research is needed on patterns of resilience among those who have successfully coped with ACEs.

description: This descriptive content analysis explored educational software evaluation forms for the use of criteria related to the concept of the common good, a major tenet of social responsibility, within the major software evaluation form categories of instructional design and content. The premise of the study was that educational software evaluation forms may serve to enhance the socio-cognitive development of secondary students, if evaluation criteria for the common good were included in the instructional design and content categories. The population consisted of thirteen educational software evaluation agencies which evaluate for the YZ Group (pseudonym), an educational evaluation organization. Nine of the twelve respondents submitted the requested data, the software evaluation forms currently in use. Both the instructional design and content categories of each software evaluation form were studied utilizing a research procedure of descriptive content analysis. A model of criteria for the common good, to be used as an educational software evaluation form category, was developed based upon fifteen tenets related to the common good derived from the literature. All data was compared to these tenets. Although representing a modest sample of the educational software evaluation population, the results of the study indicate the YZ Group is representative of a broader population (similar educational software evaluation groups) for the following reasons. First, the YZ Group, and the individual agencies which comprise it, evaluate educational software for other popular evaluation groups and their publications. Secondly, the agencies of the YZ Group are public school districts, public/private universities, and professional educational organizations, as are many of the agencies comprising other popular software evaluation groups, such as the UV and WX Groups (pseudonyms). The results of this content analysis strongly indicate that criteria for the common good are most often neglected from educational software evaluation forms. The evidence demonstrated the categories of instructional design and content on software evaluation forms included criteria promoting the common good at a rate of only 17.7%. The study also indicated that software evaluation forms were devoid of criteria for the detection of bias and stereotyping at a rate of 55.5%, as only four of the nine educational software evaluation forms included such criteria.

description: Data analysis in science, e.g., high-energy particle physics, is often subject to an intractable likelihood if the observables and observations span a high-dimensional input space. Typically the problem is solved by reducing the dimensionality using feature engineering and histograms, whereby the latter technique allows to build the likelihood using Poisson statistics. However, in the presence of systematic uncertainties represented by nuisance parameters in the likelihood, the optimal dimensionality reduction with a minimal loss of information about the parameters of interest is not known. This work presents a novel strategy to construct the dimensionality reduction with neural networks for feature engineering and a differential formulation of histograms so that the full workflow can be optimized with the result of the statistical inference, e.g., the variance of a parameter of interest, as objective. We discuss how this approach results in an estimate of the parameters of interest that is close to optimal and the applicability of the technique is demonstrated with a simple example based on pseudo-experiments and a more complex example from high-energy particle physics.

description: The purpose of this study was to understand what factors affect meat consumption among students at the University of British Columbia (UBC), in order to reduce meat consumption on campus and reduce overall environmental impact . Does the description and labeling of vegetarian dishes affect food choice for non-vegetarians? It was hypothesized that description and labeling would affect food choice among non-vegetarians in the following ways: fewer students would select a vegetarian dish compared to a meat dish when the word “vegetarian” was used in the title; more students would select a vegetarian dish compared to a meat dish when the meat/meat alternative was placed at the end of the ingredient list; and more students would select a vegetarian option when nutritional data was provided. Two hundred and thirteen surveys were collected at UBC. Results do not demonstrate consistent patterns in the effects of ingredient order, “vegetarian” label, or the presence of nutritional information across all food options. The presence of nutritional information for the chili dish significantly increased the selection of a vegetarian compared to a non-vegetarian meal. Providing nutritional information may help to decrease meat consumption. We recommend further research into which nutritional information is most persuasive.

Quasi two-body scaling in inclusive nuclear reactions
Creators: name: Papadopoulou, Demetra
Publisher: name: American University
Year: 2023

description: The hypothesis of quasi two body scaling (qtbs) in inclusive inelastic scattering by nuclei is studied. By use of qtbs, a wide range of cross section data can be correlated in terms of a universal scaling function $G(k\sb{min})$ that depends on a scaling variable $k\sb{min}.$ The scaling variable is calculated from the kinematic variables of the scattering reaction. If qtbs applies, the inelastic cross section can be written as a product of the scaling function, a known kinematic factor, and a quasielastic cross section. The quasielastic cross section can be related to experimental elastic cross sections. Then the scaling function is calculated by dividing the inelastic cross section by the two known factors. Scaling for incident electrons and for incident protons is studied, and the extent to which qtbs is valid is compared for each case. A quantitative measure of goodness of scaling is introduced using analytical fits to the scaling function for different scattering cases. Also several tests of the specific assumptions that comprise the qtbs hypothesis are introduced, and applied to the various scattering cases. An integral sum rule is derived to test whether the scaling that is observed is truly a verification of qtbs. The sum rule is well satisfied, indicating that the observed scaling does verify qtbs. Our results show that scaling is relatively good for both incident electrons and protons, but the scaling is somewhat more universal for the electrons. The production of nucleon resonances is shown to be the cause of scaling violation for negative values of the scaling variable. The electron and proton scaling functions differ in their slope on a log plot. This is attributable to a larger probability of initial and final state interactions for protons, leading to an effective scaling function for the protons. The electron scaling function is related to the nucleon momentum distribution in the nucleus. This momentum distribution is found to be universal, except for a slightly smaller slope for Helium.

description: We conducted a review of literature and of industry standards and, a survey of AMS Nest customers regarding current food signage. The literature review determined that while signage is important, too much signage may become a problem for customers and that colours and online access to information may complement existing signage. Since the AMS Sustainability Office and SEEDS are interested in improving signage to include nutritional, sustainability and allergen information, surveys of AMS food outlets’ customers were conducted for a total of 233 respondents. Two-thirds of respondents were interested in enhanced food signage in the AMS Nest. The most popular food characteristics for improving signage were identified as locally sourced, low-salt and low-sugar content. We recommend expanding signage with respect to these characteristics and offer suggestions of icons and color coding used in the industry for Uppercase, one of the AMS Nest’s food outlets. We suggest that online food information as provided by Starbucks and Tim Hortons could be used as a model for the AMS Nest food vendors. QR codes are another option that the AMS may like to utilize in future updates to food signage. This technology will allow customers to easily access additional online information using their smartphones and learn about the allergens, ingredients, dietary considerations, and nutritional information regarding the products offered without unnecessary hassle.

description: This paper considers alternative forms of regulation and taxation of the casino sector. The model considers the situation of a typical tourist destination country that is using casinos to attract and entertain foreign tourists. The objective is to invest in the sector efficiently while maximizing the amount of government revenue or profits accruing to the country. The regulator must determine how the price of gambling will be set, how many casinos will be allowed to enter the industry and the form and rates of taxation. Four alternative forms of regulation are considered: price regulation, state-owned monopoly, private monopoly and casino association regulation. Turnover taxes on the amount of funds gambled and also annual taxation of the fixed costs of the casinos are evaluated. Applications of the models are carried out for North Cyprus. The conclusion is that the economic efficiency costs and the revenue losses from the absence of effective regulation in these tourist destinations can be very substantial with welfare costs equal to the approximately 75 percent of the tax revenue generated by this sector. Furthermore it shows that while a tax on turnover can be efficient in the case of a competitive industry or a cartel association form of regulation, it will be distortunary if a private monopoly is controlling the sector. In contrast a tax on fixed costs will lead to an efficient result in the case of a competitive or private monopoly cases, but it will lead to allocate inefficiencies if the sector is regulated by a casino association that can only control the number of casino entering the sector.

description: Better machine understanding of pedestrian behaviors enables faster progress in modeling interactions between agents such as autonomous vehicles and humans. Pedestrian trajectories are not only influenced by the pedestrian itself but also by interaction with surrounding objects. Previous methods modeled these interactions by using a variety of aggregation methods that integrate different learned pedestrians states. We propose the Social Spatio-Temporal Graph Convolutional Neural Network (Social-STGCNN), which substitutes the need of aggregation methods by modeling the interactions as a graph. Our results show an improvement over the state of art by 20% on the Final Displacement Error (FDE) and an improvement on the Average Displacement Error (ADE) with 8.5 times less parameters and up to 48 times faster inference speed than previously reported methods. In addition, our model is data efficient, and exceeds previous state of the art on the ADE metric with only 20% of the training data. We propose a kernel function to embed the social interactions between pedestrians within the adjacency matrix. Through qualitative analysis, we show that our model inherited social behaviors that can be expected between pedestrians trajectories.

description: The hypothesis of quasi two body scaling (qtbs) in inclusive inelastic scattering by nuclei is studied. By use of qtbs, a wide range of cross section data can be correlated in terms of a universal scaling function $G(k\sb{min})$ that depends on a scaling variable $k\sb{min}.$ The scaling variable is calculated from the kinematic variables of the scattering reaction. If qtbs applies, the inelastic cross section can be written as a product of the scaling function, a known kinematic factor, and a quasielastic cross section. The quasielastic cross section can be related to experimental elastic cross sections. Then the scaling function is calculated by dividing the inelastic cross section by the two known factors. Scaling for incident electrons and for incident protons is studied, and the extent to which qtbs is valid is compared for each case. A quantitative measure of goodness of scaling is introduced using analytical fits to the scaling function for different scattering cases. Also several tests of the specific assumptions that comprise the qtbs hypothesis are introduced, and applied to the various scattering cases. An integral sum rule is derived to test whether the scaling that is observed is truly a verification of qtbs. The sum rule is well satisfied, indicating that the observed scaling does verify qtbs. Our results show that scaling is relatively good for both incident electrons and protons, but the scaling is somewhat more universal for the electrons. The production of nucleon resonances is shown to be the cause of scaling violation for negative values of the scaling variable. The electron and proton scaling functions differ in their slope on a log plot. This is attributable to a larger probability of initial and final state interactions for protons, leading to an effective scaling function for the protons. The electron scaling function is related to the nucleon momentum distribution in the nucleus. This momentum distribution is found to be universal, except for a slightly smaller slope for Helium.

description: The equations for a G_2-structure with torsion on a product M^7 = N^6 x S^1 are studied in relation to the induced SU(3)-structure on N^6. All solutions are found in the case when the Lee-form of the G_2-structure is non-zero and N^6 is a six-dimensional nilmanifold with half-integrable SU(3)-structure. Special properties of the torsion of these solutions are discussed.

Optimal Behavior Planning for Autonomous Driving: A Generic Mixed-Integer Formulation

description: Mixed-Integer Quadratic Programming (MIQP) has been identified as a suitable approach for finding an optimal solution to the behavior planning problem with low runtimes. Logical constraints and continuous equations are optimized alongside. However, it has only been formulated for a straight road, omitting common situations such as taking turns at intersections. This has prevented the model from being used in reality so far. Based on a triple integrator model formulation, we compute the orientation of the vehicle and model it in a disjunctive manner. That allows us to formulate linear constraints to account for the non-holonomy and collision avoidance. These constraints are approximations, for which we introduce the theory. We show the applicability in two benchmark scenarios and prove the feasibility by solving the same models using nonlinear optimization. This new model will allow researchers to leverage the benefits of MIQP, such as logical constraints, or global optimality.

description: Introduction: EverThrive Illinois has been working alongside partners and members to identify and address systemic causes of health inequities in Illinois affecting women, children, and families, through lasting policy changes. Recently, they initiated the Contraceptive Justice Project to increase access to all forms of contraception, while considering the impact of ten social determinants of health. As part of the patient/client assessment, a literature review was conducted that revealed common facilitators and barriers to contraceptive access, and major themes related to a number of social determinants of health. The literature review also revealed gaps in data regarding access to contraception for immigrant populations and the transgender community.Methods/Analysis: Four focus groups (N=57) were conducted at various community organizations in Chicago in order to address the gaps in the literature. Focus group notes were analyzed using grounded theory and an iterative process of comparison. A de-identified, open-ended, demographics questionnaire was administered and analyzed using descriptive statistics.Results: Sample consisted of presumed ciswomen (79%) and gender-expansive folks (12%) who self-identified as Latinx (51%), Black (16%), and white (21%). Four major themes emerged from the focus group discussions: sexual and reproductive health, sexual health education, physician experience, and contraception experience. Discussions revealed multiple sources of sexual and reproductive health information and that experiences of trauma were common. Sexual health education yielded positive experiences when curriculum was inclusive, comprehensive, and taught in multiple modalities. Patient-physician experiences were influenced by language, feelings of distrust, and confidentiality. Finally, when discussing contraceptive experiences, participants often mentioned side effects and cited several barriers to access to their preferred method including insurance/cost, providers pushing contraception methods, or being offered limited options.Discussion: In order to increase access to preferred methods of contraception, people seeking contraception must have access to comprehensive, inclusive, trauma-informed, and age-appropriate sexual health education. The patient-physician relationship also must be strengthened by improving communication, using understandable and inclusive language, and respecting people and their choices. Finally, contraception counseling should be RJ informed.
Well-Defined Quantum Soliton Masses Without Supersymmetry

description: 22 years ago, Rebhan and van Nieuwenhuizen showed that loop corrections to the mass of a quantum soliton depend on a choice of matching condition for the regulators of the vacuum and one-soliton sector Hamiltonians. In supersymmetric theories, regulators which preserve supersymmetry yield the correct quantum corrections, as these are dictated by supersymmetry. However, in a general theory it is not known which matching condition yields the correct mass. We use the leading term in the operator that creates the soliton to construct the regulated one-soliton sector Hamiltonian from that of the vacuum sector, providing the correct matching condition. As an application, we derive a simple formula for the one-loop mass of a kink in a large class of 1+1 dimensional scalar field theories and also, at one loop, we diagonalize the Hamiltonian which describes the kink excitations.
