Those Without History: Recaptured Africans, American Free Blacks, and the US-Liberia Connection
Creators: name: Koehler, Jacob
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis explores the early history of the Republic of Liberia, paying particular attention to the role of recaptured Africans—African people being illegally transported by slavers to become slaves in the western hemisphere who were “re-captured” by the US Navy between 1819 and 1861—within that story. This piece engages with the establishment of the American Colonization Society, the creation of the American colony that would become Liberia, and the attempts to assimilate recaptives into Liberian culture. By examining why American free blacks (later known as “Americo-Liberians”) were sent to Liberia, and why recaptured Africans were incorporated into the country by those people, this thesis aimed to answer one central question: what can the history of recaptured Africans teach a historian about the connection between Liberia and the United States? This thesis argues that the Americo-Liberian drive to incorporate recaptured Africans into the country highlighted their belief in unavoidable ethnic and cultural differences, leading them to promote the idea that settler Liberians needed to “civilize” and “uplift” those they viewed as lacking cultural refinement. I contend that the impulse to integrate and assimilate Africans into Americo-Liberian culture—and Liberia itself—was connected to the American colonization supporters’ drive to separate free blacks from the US, because both of these mindsets were premised on a sense of cultural superiority aimed at those perceived as lesser beings. Additionally, this thesis highlights the importance of recaptured Africans within the early history of Liberia, showing that they helped initiate the start of the republic, made up a significant proportion of the laboring class in the nineteenth century, and were in many regards the most incorporated group of Africans in Liberia. This thesis highlights another link between the United States and its former colony, and that connection is significant for truly understanding the early history of Liberia.

description: In this paper, we revisit the null boundary gravitational charge in the Newman-Penrose formalism with special emphasis on the charges from local Lorentz transformations. We find that there is one more charge derived from the local Lorentz transformation and the new charge is purely from the Holst term. This reveals a remarkable fact that trivial terms which do not change classical equations of motion can not only affect the boundary degrees of freedom through their contributions to the boundary charges but also have their own rights to create new boundary degrees of freedom.

description: We consider a general stochastic differential delay equation (SDDE) with state-dependent colored noises and derive its limit as the time delays and the correlation times of the noises go to zero. The work is motivated by an experiment involving an electrical circuit with noisy, delayed feedback. An Ornstein-Uhlenbeck process is used to model the colored noise. The main methods used in the proof are a theorem about convergence of solutions of stochastic differential equations by Kurtz and Protter and a maximal inequality for sums of a stationary sequence of random variables by Peligrad and Utev.

description: We study the azimuthal angular decorrelation of the dijet production via photon fusion in ultra-peripheral heavy ion collisions. The impact parameter dependent cross section of quark-antiquark pairs production is derived using the equivalent photon approximation, and the contribution from final-state QCD radiations to the azimuthal angular distribution are calculated within Soft-Collinear Effective Theory. We carry out the QCD resummation of large logarithms of the azimuthal angle as well as the jet radius at next-to-leading logarithmic accuracy. In the end we present the normalized differential cross section for azimuthal decorrelation of the dijet pair and find that our results are consistent with the measurements reported by the ATLAS collaboration.

description: Dwarf spheroidal (dSph) galaxies are prime targets for present and future gamma-ray telescopes hunting for indirect signals of particle dark matter. The interpretation of the data requires careful assessment of their dark matter content in order to derive robust constraints on candidate relic particles. Here, we use an optimised spherical Jeans analysis to reconstruct the `astrophysical factor' for both annihilating and decaying dark matter in 21 known dSphs. Improvements with respect to previous works are: (i) the use of more flexible luminosity and anisotropy profiles to minimise biases, (ii) the use of weak priors tailored on extensive sets of contamination-free mock data to improve the confidence intervals, (iii) systematic cross-checks of binned and unbinned analyses on mock and real data, and (iv) the use of mock data including stellar contamination to test the impact on reconstructed signals. Our analysis provides updated values for the dark matter content of 8 `classical' and 13 `ultrafaint' dSphs, with the quoted uncertainties directly linked to the sample size; the more flexible parametrisation we use results in changes compared to previous calculations. This translates into our ranking of potentially-brightest and most robust targets---viz., Ursa Minor, Draco, Sculptor---, and of the more promising, but uncertain targets---viz., Ursa Major 2, Coma---for annihilating dark matter. Our analysis of Segue 1 is extremely sensitive to whether we include or exclude a few marginal member stars, making this target one of the most uncertain. Our analysis illustrates challenges that will need to be addressed when inferring the dark matter content of new `ultrafaint' satellites that are beginning to be discovered in southern sky surveys.

Investigating the Benefits of Music Therapy for Mothers of Babies in the Neonatal Intensive Care Unit

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The importance of breastfeeding is widely known and supported by literary evidence, as are various interventional methods to promote breastfeeding efficacy for mothers. After a review of the current literature, a dearth of information was found surrounding the method of music therapy and its benefits for improving lactation efficacy. The literature indicates that mothers in the Neonatal Intensive Care Unit (NICU) setting are predisposed to higher levels of stress and anxiety, which negatively impacts their productivity during times of attempted lactation. The aim of this study is to investigate the experiences and perceived effectiveness of music therapy as an interventional method to increase lactation success for mothers of babies in the NICU. A qualitative semi-structured survey was administered to six lactation nurses (n=6), that sought feedback regarding their experiences with music therapy and its perceived effectiveness for mothers of these NICU babies. After cross-analyzation and comparison of the responses, the main benefits were identified through this survey. The responses from the nurses collectively expressed a perception of decreased stress/anxiety levels for NICU mothers, and a higher productivity of their lactation sessions using music therapy, which was indicated by report of increased milk yield. Conducting further quantitative research regarding the impact and magnitude of benefits that music therapy has on lactation for mothers of babies in the NICU would be beneficial to provide statistical evidence of its success, and guide further evidence-based practice.

description: We attempt to understand the CFT$_1$ structure underlying (2+1)D gravity in flat spacetime via dimensional reduction. We observe that under superrotation, the hyperbolic (and dS$_2$) slices of flat spacetime transform to asymptotically (A)dS$_2$ slices. We consider a wedge region bounded by two such surfaces as End-of-the-World branes and employ Wedge holography to perform holographic reduction. We show that once we consider fluctuating branes, the localised theory on the branes is Jackiw-Teitelboim (JT) theory. Finally, using the dual description of JT, we derive an 1D Schwarzian theory at the spatial slice of null infinity. In this dual Celestial (nearly) CFT, the superrotation mode of 3D plays the role of the Schwarzian derivative of the boundary time reparametrization mode.

The Drama of Dark Patterns: History, transformation, and why it still matters
Creators: name: Doucette, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this paper I analyze the history, actors, and power encapsulated within deceptive user interface design called “dark patterns.” I open by outlining the cultural conditions encouraging the emergence of dark patterns and describe the created relationship between the user and the programmer. The first tradition of digital infrastructure I describe, usability, presents a trained and vulnerable user through its use of simplified, abstracted, and constructed grammars. Complementary with the emergence of usability, the force of privatization creates a centralized and systematized process of software development; one that places pressure on developers to further train and orient agency towards profit. This results in a regularized definition of dark patterns – design techniques that weaponize conveniences of usability for the capture of profit. I then step to explore how this weaponization manifests itself through various types of dark patterns, and, through qualitative research, categorize dark patterns into three groups centered upon their relationship to profit. I then analyze how dark patterns adjust in response to media attention, and come to the conclusion that interface modification is more substantial in patterns with an explicit relationship with profit. I connect this with a larger trend towards increasingly concealed and opaque deception in digital infrastructure. Using techniques such as concealment, personalization, or mutability, I argue modern dark patterns accentuate the asymmetric power dynamic between the user and the programmer. In conclusion, I return to the usability’s issue of creating a vulnerable and trained user, and push for interface design that encourages greater digital literacy; I also connect dark patterns to a larger history of neoliberalism and note that an attempt to work against deceptive design should look to work against the privatization of technology as well.

description: For both the FCC-ee and the ILC, to exploit properly the respective precision physics program, the theoretical precision tag on the respective luminosity will need to be improved from the analogs of the $ 0.054 \% (0.061\%)$ results at LEP at $M_Z$, where the former (latter) LEP result has (does not have) the pairs correction. At the FCC-ee at $M_Z$ one needs improvement to $0.01\%$, for example. We present an overview of the roads one may take to reach the required $0.01\%$ precision tag at the FCC-ee and of what the corresponding precision expectations would be for the FCC-ee$_{350}$, ILC$_{500}$, ILC$_{1000}$, and CLIC$_{3000}$ setups.

description: We show that pure quadratic gravity with quantum loop corrections yields a viable inflationary scenario. We also show that a large family of models in the Jordan frame, with softly-broken scale invariance, corresponds to the same theory with linear inflaton potential in the Einstein frame. It follows that all these quasi scale-invariant models have the same relation between the tensor-to-scalar ratio and the scalar spectral index, which is also consistent with the current data. Thus, they form a family of attractors, which is sharply distinct from the recently discovered $α$-attractors of Kallosh, Linde et al.

Exact two-component TDDFT with simple two-electron picture-change corrections: X-ray absorption spectra near L- and M-edges of four-component quality at two-component cost

description: X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivity. However, the theoretical modelling of XAS is a challenging task since XAS spectra feature a fine structure due to scalar (SC) and spin-orbit (SO) relativistic effects, in particular near L and M absorption edges. While full four-component (4c) calculations of XAS are nowadays feasible, there is still interest in developing approximate relativistic methods that enable XAS calculations at the two-component (2c) level while maintaining the accuracy of the parent 4c approach. In this article we present theoretical and numerical insights into two simple yet accurate 2c approaches based on an (extended) atomic mean-field exact two-component Hamiltonian framework, (e)amfX2C, for the calculation of XAS using linear eigenvalue and damped-response time-dependent density functional theory (TDDFT). In contrast to the commonly used one-electron X2C (1eX2C) Hamiltonian, both amfX2C and eamfX2C account for the SC and SO two-electron and exchange-correlation picture-change (PC) effects that arise from the X2C transformation. As we demonstrate on L- and M-edge XAS spectra of transition metal and actinide compounds, the absence of PC corrections in the 1eX2C approximation results in a substantial overestimatation of SO splittings, whereas (e)amfX2C Hamiltonians reproduce all essential spectral features such as shape, position, and SO splitting of the 4c references in excellent agreement, while offering significant computational savings. Therefore, the (e)amfX2C PC correction models presented here constitute reliable relativistic 2c quantum-chemical approaches for modelling XAS.

In the latter case, we show how delayed feedback control can be used to restore the visibility of the ESQPT signals.

description: Following inflation, the Universe may pass through an early matter-dominated phase supported by the oscillating inflaton condensate. Initially small fluctuations in the condensate grow gravitationally on subhorizon scales and can collapse to form nonlinear ``inflaton halos''. Their formation and subsequent tidal interactions will source gravitational waves, resulting in a stochastic background in the present Universe. We extend N-body simulations that model the growth and interaction of collapsed structures to compute the resulting gravitational wave emission. The spectrum of this radiation is well-matched by semi-analytical estimates based on the collapse of inflaton halos and their tidal evolution. We use this semi-analytic formalism to infer the spectrum for scenarios where the early matter-dominated phase gives way to a thermalized universe at temperatures as low as $100\,\mathrm{MeV}$ and we discuss the possible experimental opportunities created by this signal in inflationary models in which thermalization takes place long after inflation has completed.

Implication of Spatial and Temporal Variations of the Fine-Structure Constant

description: Temporal and spatial variation of fine-structure constant $α\equiv e^2/\hbar c$ in cosmology has been reported in analysis of combination Keck and VLT data. This paper studies this variation based on consideration of basic spacetime symmetry in physics. Both laboratory $α_0$ and distant $α_z$ are deduced from relativistic spectrum equations of atoms (e.g.,hydrogen atom) defined in inertial reference system. When Einstein's $Λ\neq 0$, the metric of local inertial reference systems in SM of cosmology is Beltrami metric instead of Minkowski, and the basic spacetime symmetry has to be de Sitter (dS) group. The corresponding special relativity (SR) is dS-SR. A model based on dS-SR is suggested. Comparing the predictions on $α$-varying with the data, the parameters are determined. The best-fit dipole mode in $α$'s spatial varying is reproduced by this dS-SR model. $α$-varyings in whole sky is also studied. The results are generally in agreement with the estimations of observations. The main conclusion is that the phenomenon of $α$-varying cosmologically with dipole mode dominating is due to the de Sitter (or anti de Sitter) spacetime symmetry with a Minkowski point in an extended special relativity called de Sitter invariant special relativity (dS-SR) developed by Dirac-Inönü-Wigner-Gürsey-Lee-Lu-Zou-Guo.

We first write the Lagrangian consisting of the Einstein-Hilbert term, Dirac term and a scalar field term in a non-Riemannian spacetime with curvature and torsion. Then by solving the affine connection analytically we reformulate the theory in the Riemannian spacetime in a self-consistent way. Finally we discuss our results and give future perspectives on the subject.

Cardiometabolic Disease Risk and College Students: Relationships Between Inflammation, Psychosocial Stress, and Diet
Creators: name: Cochran, Robert Z.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

Subjects: Medical anthropology

description: Diet is a factor that has been shown to mitigate the impacts of cardiometabolic disease (CMD) risk in adult populations while sustained levels of psychosocial stress has been shown to worsen the impacts of CMD. Inflammation is a possible pathway through which these lifestyle and behavioral factors impact CMD risk. This poses an alarming issue for populations that are predisposed to higher levels of sustained psychosocial stress – college students. This study seeks to define the most prominent factors interlinking diet, psychosocial stress, and inflammation as it pertains to CMD risk in college students. Data collection processes included the use of questionnaires, anthropometric measurements, and biomarkers of stress (cortisol) and inflammation (C-Reactive Protein). These methods were used to (1) examine the relationship between BMI, central adiposity, and CMD risk, (2) assess the effects of psychosocial stress on subsequent inflammation profiles, and (3) explore how dietary practices may underlie the quantitative data surrounding stress and CMD risk. Data were collected on 21 UNC Chapel Hill undergraduates. Findings suggest increased psychosocial stress can be regarded as a prominent factor in underlying CMD risk among college students as cortisol levels and CRP levels have positive linear relationship. In addition, a diet falling in line with the Western Diet can be associated with increased CMD risk based on inflammatory profiles generated from CRP levels and anthropometric data. These results support the combination of dietary and stress interventions for reducing inflammation and down-regulating the negative impacts of psychosocial stress on CMD risk in college students.

description: Statistical analysis and inference on spike trains is one of the central topics in the neural coding. It is of great interest to understand the underlying structure of given neural data. Based on the metric distances between spike trains, recent investigations have introduced the notion of an average or prototype spike train to characterize the template pattern in the neural activity. However, as those metrics lack certain Euclidean properties, the defined averages are nonunique, and do not share the conventional properties of a mean. In this article, we propose a new framework to define the mean spike train where we adopt a Euclidean-like metric from an $L^p$ family. We demonstrate that this new mean spike train properly represents the average pattern in the conventional fashion, and can be effectively computed using a theoretically-proven convergent procedure. We compare this mean with other spike train averages and demonstrate its superiority. Furthermore, we apply the new framework in a recording from rodent geniculate ganglion, where background firing activity is a common issue for neural coding. We show that the proposed mean spike train can be utilized to remove the background noise and improve decoding performance.

description: Financial management practices in the faith based areas at large and in the churches specifically is not the recent development. Despite its age, the financial management practice has been challenged in the church because of two main reasons; the first is the source of income arise from volunteers, there is a thought not to monitor the resources with adequate professionals since it is seemed to be holy and the second is the sacred and secular divide the church in which separates the financial management to the secular one and seen as it is a profane. The existence of the aforementioned challenges on one hand and the ever growing resources of the Ethiopian Evangelical Church Mekane Yesus (EECMY) on the other hand are the two paradoxes. The study assessed the financial management practice of the EECMY for administering its financial resources within its structure. Population of the study consists of the 28 church units (synods) and 7 joint programs of the church, total of 35. The study was conducted based on purposively selected 15 church units and 5 joint programs.
Chemical profiles of composite intrusions of the Independence dike swarm in eastern California

description: The 148 Ma Independence dike swarm located in eastern California consists of composite dikes. The multiple intrusions contained within a single dike, known as dikelets, differ in major and trace element concentrations. In syntaxial dikes, where younger dikelets intrude older dikelets down the middle, there is a symmetrical chemical profile displayed across the width of the dike. This confirms that the mode of intrusion is syntaxial since dikelets of the same intrusion event have the same major and trace element concentrations. The multiple intrusion events syntaxial dikes experience causes preexisting dikelets and rock to experience high temperatures during intrusion. Whereas it was expected that the fabric of the outermost dikelet would realign subparallel to the heat flow direction due to cycles in temperature, the grains had no preferred orientation. This could be because there was never any strong perpendicular to dike margin orientation of the grains due to the limited number of thermal cycles (two). Alternatively, textures developed during thermal cycling may have been overprinted during the emplacement of Cretaceous plutons and growth of greenschist facies mineral assemblages in the dikes. Understanding the details of the geochemistry and texture can help construct models on the how the swarm was emplaced.

description: The non-Gaussian measures of the particle number fluctuations -- skewness $Sσ$ and kurtosis $κσ^2$ -- are calculated in a vicinity of the critical point. This point corresponds to the end point of the first-order liquid-gas phase transition. The gaseous phase is characterized by the positive values of skewness while the liquid phase has negative skew. The kurtosis appears to be significantly negative at the critical density and supercritical temperatures. The skewness and kurtosis diverge at the critical point. The classical van der Waals equation of state in the grand canonical ensemble formulation is used in our studies. Neglecting effects of the quantum statistics we succeed to obtain the analytical expressions for the rich structures of the skewness and kurtosis in a wide region around the critical point. These results have universal form, i.e., they do not depend on particular values of the van der Waals parameters $a$ and $b$. The strongly intensive measures of particle number and energy fluctuations are also considered and show singular behavior in the vicinity of the critical point.

description: Detecting anomalies in time series data is important in a variety of fields, including system monitoring, healthcare, and cybersecurity. While the abundance of available methods makes it difficult to choose the most appropriate method for a given application, each method has its strengths in detecting certain types of anomalies. In this study, we compare six unsupervised anomaly detection methods of varying complexity to determine whether more complex methods generally perform better and if certain methods are better suited to certain types of anomalies. We evaluated the methods using the UCR anomaly archive, a recent benchmark dataset for anomaly detection. We analyzed the results on a dataset and anomaly type level after adjusting the necessary hyperparameters for each method. Additionally, we assessed the ability of each method to incorporate prior knowledge about anomalies and examined the differences between point-wise and sequence-wise features. Our experiments show that classical machine learning methods generally outperform deep learning methods across a range of anomaly types.

Year: 2020

description: The purpose of this research study is to understand the lived experience of a young adult cancer survivor. Through a qualitative case study design with photovoice methodology, both narrative and photographic storytelling modalities were utilized to gain insight into the lived experience of cancer from a young adult osteosarcoma survivor’s perspective. The selected participant engaged in introspective self-reflection in order to communicate what she felt was most important for others to know about her experience. Using thematic analysis, the findings were then synthesized into four themes: “Physical and Psychosocial Challenges,” “Coping with the Diagnosis,” “Reflection on Post-Cancer Identity and Future Outlook,” and “Words of Wisdom.”
