Comparison of Discrimination Association Tasks to Test Cognitive Flexibility in Rats
Creators: name: Crosswell, Molly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Cognitive flexibility is an executive function that refers to the ability to alter behavior according to changes in one’s environment. While adolescents with a history of binge drinking have been shown to differ cognitively from abstinent adolescents, the long-term effects of adolescent alcohol exposure are largely unknown. We hypothesized that adolescent intermittent ethanol (AIE) exposed rats would demonstrate decreased cognitive flexibility in comparison to control rats. Specifically, we tested the reversal learning and set shifting ability of 80 Sprague-Dawley rats with an attentional set-shifting digging task. Our results demonstrated impaired reversal learning and set shifting abilities in AIE subjects, specifically in the second reversal. To improve the standardization of this method and further explore the long-term impact of adolescent alcohol exposure, we adapted this reversal learning protocol to an automated, operant chamber-based task. A cue was used to indicate the correct lever, and a reward was delivered if this lever was pressed. Two studies were performed, one used lights as cues and the other used tones. The rats underwent a training period to become accustomed to the box and learn the stimulus-reward associations. We found that most of the rats were able to complete the training days but were not able to reliably discriminate between the light stimuli. Subsequently, when tones were used as stimuli instead of lights, rats progressed through training faster, suggesting that tones are a more effective stimulus than lights. We conclude that our training criteria is attainable, but factors such as reward size, number of test sessions and trial criteria must be adjusted to improve acquisition performance. If acquisition performance is improved, an automated operant chamber protocol could provide valuable insight into the long-term cognitive impact of adolescent alcohol exposure.

description: According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will be dragged towards the disc-plane, depositing stars and dark matter into an accreted disc structure. In this work, we utilize the chemo-dynamical template developed in Ruchti et al. to hunt for accreted stars. We apply the template to a sample of 4,675 stars in the third internal data release from the Gaia-ESO Spectroscopic Survey. We find a significant component of accreted halo stars, but find no evidence of an accreted disc component. This suggests that the Milky Way has had a rather quiescent merger history since its disc formed some 8-10 billion years ago and therefore possesses no significant dark matter disc.

Exploring Online Heterosexist Discrimination Using Meyer's Minority Stress Model
Creators: name: Carson, Ian William
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Clinical psychology

description: AIM People with marginalized sexual orientations experience mental health and substance use problems at a higher rate compared to heterosexuals. Experiences of discrimination have been identified as a significant factor in explaining such disparities, and a growing body of literature has developed seeking to explore the contexts in which discrimination occurs. However, one context that is understudied is the online environment. Based on Meyer’s (2003) Minority Stress Model (MSM), it is postulated that specific proximal group-specific processes mediate the relationship between discrimination and health outcomes, with other social factors providing protective effects. However, research is sparse empirically investigating different mechanisms, consequences, and potential modifying factors for sexual minority young adults experiencing online heterosexist discrimination (OHD). Thus, the current study aims to explore experiences of OHD among young adults. METHODS Using the MSM as a guiding framework, the study examined proximal factors of internalized heterosexism, online concealment, and rejection sensitivity as mechanisms underlying the effect of OHD on health outcomes and online social support as a moderating factor. 383 young adults (18-35) with marginalized sexual orientations were recruited from an introductory psychology subject pool, two online crowdsourcing platforms (Prolific, MTurk), and the community. They completed measures of OHD, online social support, online concealment, rejection sensitivity, internalized heterosexism, psychological distress, and substance use. RESULTS Path analyses in Mplus revealed that two proximal stressors (rejection sensitivity, sexual orientation concealment) were positively related to psychological distress as a result of OHD. Sexual orientation concealment was associated with increased risk for cannabis use due to OHD. Online social support from LGBTQ+ peers did not buffer these relationships. CONCLUSION The MSM is a viable guiding framework in exploring OHD. Rejection sensitivity and online sexual orientation concealment are important constructs to consider for future research and may be ideal treatment targets for individuals experiencing psychological distress or engaging in cannabis use due to OHD.

description: We report on the implementation of a high fidelity universal gate-set on optical qubits based on trapped $^{88}$Sr$^+$ ions for the purpose of quantum information processing. All coherent operations were performed using a narrow linewidth diode laser. We employed a master-slave configuration for the laser, where an ultra low expansion glass (ULE) Fabry-Perot cavity is used as a stable reference as well as a spectral filter. We characterized the laser spectrum using the ions with a modified Ramsey sequence which eliminated the affect of the magnetic field noise. We demonstrated high fidelity single qubit gates with individual addressing, based on inhomogeneous micromotion, on a two-ion chain as well as the Mølmer-Sørensen two-qubit entangling gate.

An Examination of Supervisors' Implicit Person Theory and the Supervisor-Employee Relationship
Creators: name: Chavez, Emily K
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Industrial and organisational psychology (incl. human factors)

description: Previous research has established that supervisor’s play an important role in conveying performance management strategies and influencing an employee’s job experience. Notably, there has been a growing area of research of how Implicit Person Theory (IPT) can contribute to supervisors’ coaching and management styles. Research within the more recent years has shown that IPT has indirect effects on the employee experience. The current study expands upon both IPT and performance management literature, by examining how an employee perceives their Supervisor’s IPT, their supervisor’s coaching style of support for developmental opportunities, and the employee’s related job outcomes of: Turnover Intentions, Job Satisfaction, and Satisfaction with Supervisor. Results from 388 men and women in various industries and organizations suggest that Perceived Supervisor IPT is related to developmental opportunities within the workplace. Additionally, we found support for Supervisor IPT being indirectly related to employees’ Turnover Intentions, Job Satisfaction, and Satisfaction with Supervisor via Perceived Developmental Opportunities. When adding Employee IPT to our mediated model, we only found marginally significant support for employees’ Satisfaction with Supervisor. Additionally, we controlled for Leader Member Exchange (LMX) within our moderated mediation model and found non- significant interactions on the indirect path of Perceived Developmental Opportunities on all three employee outcomes and obtained non-significant mediations nested within our greater model. Within our exploratory analyses we found evidence of IPT interaction between an employee and supervisor predicting LMX, Turnover Intentions, and Job Satisfaction. Ultimately, this research contributes to performance management, IPT, and LMX research by providing evidence of how a developmental coaching style of providing opportunities to employees can influence the employees’ job experience and is related to their perceptions of their leader.

description: The odd-odd 54;56;58;60;62;64Mn isotopes (Z = 25) were studied using bunched-beam collinear laser spectroscopy at ISOLDE, CERN. From the measured hyperfine spectra the spins and magnetic moments of Mn isotopes up to N = 39 were extracted. The previous tentative ground state spin assignments of 58;60;62;64Mn are now firmly determined to be I = 1 along with an I = 4 assignment for the isomeric states in 58;60;62Mn. The I = 1 magnetic moments show a decreasing trend with increasing neutron number while the I = 4 moments remain quite constant between N = 33 and N = 37. The results are compared to large-scale shell-model calculations using the GXPF1A and LNPS effective interactions. The excellent agreement of the ground state moments with the predictions from the LNPS calculations illustrates the need for an increasing amount of proton excitations across Z = 28 and neutron excitations across N = 40 in the ground state wave functions from N = 37 onwards.
Effects of adolescent binge ethanol exposure on striatal parvalbumin
Creators: name: Jawad, Rayyanoor
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Binge drinking is the most common, costly, and deadly pattern of excessive alcohol use in the United States. About 27% of people ages 18 or older reported binge drinking in the past month. Studies show that binge drinking among adolescents may lead to alcohol-use disorders later in life. Animal models of binge drinking show that adolescent intermittent ethanol (AIE) exposure in rodents can alter synaptic physiology, sensitivity to alcohol, and behavior and cause the adolescent-like phenotype to persist into adulthood. Striatal subregions play distinct roles in the integration of social information and coordinated movement, but alcohol exposure has been shown to cause dysfunctional connectivity and deficits in neuronal activity, inhibiting striatal output. A decrease of parvalbumin (PV) neurons in various brain regions has been associated with deficits in cognitive control and decision-making, most likely because PV interneurons regulate the excitatory/inhibitory balance that drive appropriate behavioral responses. Some studies have investigated the effect of perinatal alcohol exposure on PV in various brain regions, however, the effect of binge level alcohol exposure on PV, specifically in the striatum, is unknown. The present study is the first to test AIE-induced effects on striatal PV. We hypothesized that AIE-induced reductions in PV interneuron markers are associated with AIE reductions in behavioral flexibility and functional connectivity. However, using immunohistochemistry (IHC) and fluorescent microscopy, we report here that AIE does not significantly alter striatal PV+IR interneurons (p > 0.05) and PV interneurons do not play a significant role in the genesis of the behavioral deficits associated with each striatal subregion.
Executive Functioning in Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder: A Multimodal Approach
Creators: name: McQueen, Emma
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Executive functions (EF) encompass several higher-order cognitive processes that are necessary for preparing and performing goal-directed behavior in which automatic behaviors are not enough. This includes processes such as task initiation, planning, flexibility, working memory, self-regulation, emotions, response inhibition and attention to focus on the task at hand. Executive functioning deficits are often seen in individuals with neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). This study used a multimodal approach to characterize EF in ADHD and ASD and had three linked aims; (1) Using a tablet-based measure (the NIH Toolbox) to understand performance-based EF in 51 aged 5-17 year old's; (2) in a sub-set of 28 aged 7-12 year old's, characterize EF using parent report and (3) in the same sub-set sample, understand the neural correlates of EF using two ERP paradigms.  Compared to children with ADHD and TD, children with ASD were impaired in inhibition measured via the NIH-TB Flanker Inhibitory Control and Attention Test. Children with ADHD exhibited attenuated P3 amplitudes as well as delayed N2 and P3 latency compared to TD participants. These components are assumed to index response inhibition, conflict monitoring and working memory. Overall findings from this multimodal study suggest that executive functioning deficits remain a target of intervention approaches across ADHD and ASD.

A Finite Element Model for Investigation of Nuclear Stresses in Arterial Endothelial Cells

description: Cellular structural mechanics play a key role in homeostasis by transducing mechanical signals to regulate gene expression and by providing adaptive structural stability for the cell. The alteration of nuclear mechanics in various laminopathies and in natural aging can damage these key functions. Arterial endothelial cells appear to be especially vulnerable due to the importance of shear force mechanotransduction to structure and gene regulation as is made evident by the prominent role of atherosclerosis in Hutchinson-Gilford progeria syndrome (HGPS) and in natural aging. Computational models of cellular mechanics may provide a useful tool for exploring the structural hypothesis of laminopathy at the intracellular level. This thesis explores this topic by introducing the biological background of cellular mechanics and lamin proteins in arterial endothelial cells, investigating disease states related to aberrant lamin proteins, and exploring computational models of the cell structure. It then presents a finite element model designed specifically for investigation of nuclear shear forces in arterial endothelial cells. Model results demonstrate that changes in nuclear material properties consistent with those observed in progerin-expressing cells may result in substantial increases in stress concentrations on the nuclear membrane. This supports the hypothesis that progerin disrupts homeostatic regulation of gene expression in response to hemodynamic shear by altering the mechanical properties of the nucleus.

description: Topological invariants built from the periodic Bloch functions characterize new phases of matter, such as topological insulators and topological superconductors. The most important topological invariant is the Chern number that explains the quantized conductance of the quantum Hall effect. Here, we provide a general result for the superfluid weight $D_{\rm s}$ of a multiband superconductor that is applicable to topologically nontrivial bands with nonzero Chern number $C$. We find that the integral over the Brillouin zone of the quantum metric, an invariant calculated from the Bloch functions, gives the superfluid weight in a flat band, with the bound $D_{\rm s} \geq |C|$. Thus, even a flat band can carry finite superfluid current, provided the Chern number is nonzero. As an example, we provide $D_{\rm s}$ for the time-reversal invariant attractive Harper-Hubbard model that can be experimentally tested in ultracold gases. In general, our results establish that a topologically nontrivial flat band is a promising concept for increasing the critical temperature of the superconducting transition.

description: Finding self-similarity is a key step for understanding the governing law behind complex physical phenomena. Traditional methods for identifying self-similarity often rely on specific models, which can introduce significant bias. In this paper, we present a novel neural network-based approach that discovers self-similarity directly from observed data, without presupposing any models. The presence of self-similar solutions in a physical problem signals that the governing law contains a function whose arguments are given by power-law monomials of physical parameters, which are characterized by power-law exponents. The basic idea is to enforce such particular forms structurally in a neural network in a parametrized way. We train the neural network model using the observed data, and when the training is successful, we can extract the power exponents that characterize scale-transformation symmetries of the physical problem. We demonstrate the effectiveness of our method with both synthetic and experimental data, validating its potential as a robust, model-independent tool for exploring self-similarity in complex systems.

Bezout's Theorem in Tropical Algebraic Geometry
Creators: name: Lang, Mingming
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this thesis, a version of Bezout's theorem in tropical geometry is studied. The classical Bezout's theorem counts the number of intersections for two curves defined on an algebraically closed field, for which we motivate and define relevant concepts such as intersection numbers. We introduce the basics of tropical geometry, including the arithmetic on the tropical semiring and tropical analogues of polynomials, roots and curves. The algebraic and geometric properties of tropical curves are studied and concluded in Kapranov's theorem and the structure theorem. We construct an analogue of intersection numbers in tropical geometry. A version of tropical B\'ezout's theorem for one kind of tropical curves is presented and proved, and a generalization on all tropical curves in general position is discussed.

description: We study the classical dynamics of the Abelian Higgs model employing an asymptotic multiscale expansion method, which uses the ratio of the Higgs to the gauge field amplitudes as a small parameter. We derive an effective nonlinear Schrödinger equation for the gauge field, and a linear equation for the scalar field containing the gauge field as a nonlinear source. This equation is used to predict the existence of oscillons and oscillating kinks for certain regimes of the ratio of the Higgs to the gauge field masses. Results of numerical simulations are found to be in very good agreement with the analytical findings, and show that the oscillons are robust, while kinks are unstable. It is also demonstrated that oscillons emerge spontaneously as a result of the onset of the modulational instability of plane wave solutions of the model. Connections of the obtained solutions with the phenomenology of superconductors is discussed.

description: We obtain a reduction scheme for the study of the quantum evolution of an atom in constant magnetic fields using the method developed by Martinez, Nenciu and Sordoni based on the construction of almost invariant subspace. In Martinez-Sordoni \cite{MaSo2} such a case is also studied but their reduced Hamiltonian includes the vector potential terms. In this paper, using the center of mass coordinates and constructing the almost invariant subspace different from theirs, we obtain the reduced Hamiltonian which does not include the vector potential terms. Using the reduced evolution we also obtain the asymptotic expantion of the evolution for a specific localized initial data, which verifies the straight motion of an atom in constatnt magnetic fields.

description: Gene expression programming is an evolutionary optimization algorithm with the potential to generate interpretable and easily implementable equations for regression problems. Despite knowledge gained from previous optimizations being potentially available, the initial candidate solutions are typically generated randomly at the beginning and often only include features or terms based on preliminary user assumptions. This random initial guess, which lacks constraints on the search space, typically results in higher computational costs in the search for an optimal solution. Meanwhile, transfer learning, a technique to reuse parts of trained models, has been successfully applied to neural networks. However, no generalized strategy for its use exists for symbolic regression in the context of evolutionary algorithms. In this work, we propose an approach for integrating transfer learning with gene expression programming applied to symbolic regression. The constructed framework integrates Natural Language Processing techniques to discern correlations and recurring patterns from equations explored during previous optimizations. This integration facilitates the transfer of acquired knowledge from similar tasks to new ones. Through empirical evaluation of the extended framework across a range of univariate problems from an open database and from the field of computational fluid dynamics, our results affirm that initial solutions derived via a transfer learning mechanism enhance the algorithm's convergence rate towards improved solutions.
The Influence of Peers and Appearance Control Beliefs on Implicit Weight Bias
Creators: name: Newsome, Faith

Year: 2020

description: Millions of people in the United States experience obesity and, with it, psychological distress from weight bias. Most studies involving implicit weight bias have been conducted using older samples and typically include healthcare professionals as study participants. This paper specifically explores implicit weight bias, and factors that may contribute to differing levels of bias, in a diverse sample of female college students aged 17-26. In this study, participants (N = 195) completed a questionnaire prior to attending the lab for an in-person visit. The questionnaire included questions about appearance control beliefs and asked participants to list up to five friends and categorize their weight status. Participants then came into the lab to complete the Affect Misattribution Procedure (AMP) as a measure of implicit weight bias. Results showed that neither a participant’s appearance control beliefs nor having friends who were overweight was associated with levels of implicit weight bias. Future research should continue to explore factors that may influence implicit weight bias in younger, more diverse samples.

description: A double well loaded with bosonic atoms represents an ideal candidate to simulate some of the most interesting aspects in the phenomenology of thermalisation and equilibration. Here we report an exhaustive analysis of the dynamics and steady state properties of such a system locally in contact with different temperature reservoirs. We show that thermalisation only occurs 'accidentally'. We further examine the nonclassical features and energy fluxes implied by the dynamics of the double-well system, thus exploring its finite-time thermodynamics in relation to the settlement of nonclassical correlations between the wells.

The Ethicality of Patient-Targeted Googling
Creators: name: Fitz, Morgan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description:      As technology and internet usage continues to expand in our society, the health professions need to consider possible implications on ethical practice.  A relatively new term, patient-targeted googling, or PTG, is described as the use of social media or search engines to discover patient information.  This practice is not explicitly prohibited by HIPAA, which focuses on the sharing of private health information, but this may be because HIPAA guidelines were established before widespread internet searches were commonplace.  Currently there are no established universal guidelines to govern PTG, which leaves the topic open to considerable debate.  The researchers used 3 means to obtain information on PTG.  First, a literature review revealed arguments both for and against PTG use, and the need for guidelines.  Secondly, the researchers used the common themes found in the literature review to guide an interview with experts and tapped members of the UNC Ethics Committee.  The ethics committee argued wholly against the practice and strongly supported the need for guidelines so that health care providers could be more aware of PTG as an ethical violation.  The literature and the interview helped shape a 19-item questionnaire that was to be administered to 106 undergraduate nursing students at UNC Chapel Hill.  The intention of the survey was to measure the prevalence of PTG amongst nursing students.  However, due to COVID-19 and the switch to online classes, the survey was not administered.  Even without the survey data, this project clearly identifies the need for interprofessional guidelines on PTG.

description: Service sharing is a prominent operating model to support business. Many large inter-organizational networks have implemented some form of value added integrated services in order to reach efficiency and to reduce costs sustainably. Coupling Service orientation with enterprise architecture paradigm is very important at improving organizational performance through business process optimization. Indeed, enterprise architecture management is increasingly discussed because of information system role as part of achieving the strategic direction of value creation and contribution to economic growth. Also, system architecture promotes synergy and business efficiency for inter-organizational collaboration. For this purpose, this work proposes a review of service oriented enterprise architecture. This review, enumerates several integrative and collaborative frameworks for integrated service delivery.

SIKKIMESE ORIGIN NEPALI (GORKHALI) AS AN ABORIGINAL TRIBE OF SIKKIM -PART I

description: The people who are living in the Himalayan region of Sikkim having their Langua-franka “Nepali” are the aboriginal tribe of Sikkim. Within the Nepali community, there are many local dialects for their communication however this community is a single entity as Nepali (Gorkhali). Back to the history, the vast land of Nepal renounced by the Rajah of Nepal after the signing the treaty of Segowlee on the 2nd day of December 1815. The treaty received by the East India Company from Chunder Seekur Opedeea, Agent on the part of the Rajah of Nipal, in the valley of Muckwaunpoor, at half past two o’clock p.m. on the 4th of March 1816 where the article 2nd of the treaty ceded the sovereignty of some parts of Nepal to British. On the otherhand, the Treaty of Titalia,1817 ceded, transferred and made full sovereignty to the Sikkimputte Rajahs, his heirs or successors, all the hilly or mountainous country situated to the eastward of the Mechi river and to the westward of the Teesta river, formerly possessed by the Rajah of Nepaul. This article I of the Treaty of Titalia 1817 shifted the power of sovereignty to the Rajah of Sikkim. It was ratified by the Governor-General in Council at Fort William on this Fifteenth day of March, One Thousand Eight Hundred and Seventeen. Having said that the legal binding of article 5th of abovementioned treaty to the Nepalese after the loss of Anglo-Nepalese War was that the Rajah of Nipal was not allowed to engage with renounced parts or inhabitants. The resulted Nepali (Gorkhali) got separated and disconnected along with the land mass in the different parts of India. Further the British granted, in another writing in 1817, to the Rajah of Sikkim to make the laws and regulations to the territories in question which was ceded from the Nepal. Thus, the people who remain in the Sikkim are the aboriginal tribe of Sikkim with their land.
Leptogenesis in $E_6 \times U(1)_A$ SUSY GUT model

description: We study the thermal leptogenesis in the $E_6\times U(1)_A$ SUSY GUT model in which realistic masses and mixings of quarks and leptons can be realized. We show that the sufficient baryon number can be produced by the leptogenesis in the model, in which the mass parameter of the lightest right-handed neutrino is predicted to be smaller than $10^8$ GeV. The essential point is that the mass of the lightest right-handed neutrino can be enhanced in the model because it has a lot of mass terms whose mass parameters are predicted to be the same order of magnitude which is smaller than $10^8$ GeV. We show that O(10) enhancement for the lightest right-handed neutrino mass is sufficient for the observed baryon asymmetry. Note that such mass enhancements do not change the predictions of neutrino masses and mixings at the low energy scale in the $E_6$ model which has six right-handed neutrinos. In the calculation, we include the effects of supersymmetry and flavor in final states of the right-handed neutrino decay. We show that the effect of supersymmetry is quite important even in the strong washout regime when the effect of flavor is included. This is because the washout effects on the asymmetries both of the muon and the electron become weaker than that of the tau asymmetry.

The Lived Experience of Waiting for a Heart Transplant
Creators: name: Urbina, Ismael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In the United States, 3,782 patients are on the waitlist for a heart transplant as of November 2019. Heart transplants are often the last hope for patients with end-stage heart failure. There are multiple conditions that can lead to heart failure such as ischemic heart disease, congenital heart defects, and arrhythmias. Obesity and diabetes are both contributing factors to the increasing prevalence of heart failure. It is estimated that by the year 2030 the number of people diagnosed with heart failure will increase by 46 percent. As a result, the need for donor hearts is expected to continue to rise. Although heart transplants have shown to be an effective treatment option for end-stage heart failure, most patients spend months waiting to receive a donor’s heart. Consequently, patients often physically deteriorate and some die while waiting. Due to the uncertainty during the wait and the progressive nature of heart failure, patients face a variety of psychological, emotional, and physical problems while waiting for a heart transplant. Understanding the challenges patients face while waiting for heart transplants can improve care during the wait and improve post-transplant outcomes. This study aims to describe the current lived experience of patients waiting for heart transplants in the hospital and home settings.
