Consequences of power transforms in linear mixed-effects models of chronometric data
Creators: name: Liceralde, Van Rynald
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Psycholinguists regularly use power transforms in linear mixed-effects models of chronometric data to avoid violating the statistical assumption of residual normality. Here, I extend previous demonstrations of the consequences of using power transforms to a wide range of sample sizes by analyzing word recognition megastudies and performing Monte Carlo simulations. Analyses of the megastudies revealed that stronger power transforms were associated with greater changes in fixed-effect test statistics and random-effect correlation patterns as they appear in the raw scale. The simulations reinforced these findings and revealed that models fit to transformed data tended to be more powerful in detecting main effects in smaller samples but were less powerful in detecting interactions as sample sizes increased. These results suggest that the decision to use a power transform should be motivated by hypotheses about how the predictors relate to chronometric data instead of the desire to meet the normality assumption.

description: NGC147, NGC185 and CassiopeiaII (CassII) have similar positions in the sky, distances and measured line of sight velocities. This proximity in phase space suggests that these three satellites of M31 form a subgroup within the Local Group. Nevertheless, the differences in their star formation history and interstellar medium, and the recent discovery of a stellar stream in NGC~147, combined with the lack of tidal features in the other two satellites, are all indications of complex and diverse interactions between M31 and these three satellites. We use a genetic algorithm to explore the different orbits that these satellites can have and select six sets of orbits that could best explain the observational features of the NGC147, NGC185 and CassII satellites. The parameters of these orbits are then used as a starting point for N-body simulations. We present models for which NGC147, NGC185 and CassII are a bound group for a total time of at least one Gyr but still undergo different interactions with M31 and as a result NGC147 has a clear stellar stream whereas the other two satellites have no significant tidal features. This result shows that it is possible to find solutions that reproduce the contrasting properties of the satellites and for which NGC147-NGC185-CassII have been gravitationally bound.

State trajectories of suffrage in the United States, 1900-1950
Creators: name: Russo, Rosemary
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: One of the most important components of a democratic state is the degree to which the citizenry can freely elect their leaders. Most political systems call for the universal suffrage of the citizenry, although this is rarely a reality. This paper adds to the current scholarship on suffrage by providing a new, more comprehensive measure for suffrage in the United States in the first half of the twentieth century which allows for the inclusion of extensions that occurred during that time as well as suffrage retractions such as poll taxes, literacy, felon disenfranchisement, and citizenship. Using this new measure, this project then provides longitudinal trajectories of each state's suffrage expansions, and retractions during the first half of the twentieth century. A preliminary analysis of these trajectories is then completed in order to empirically test several theories on suffrage extensions and retractions and some mixed support of these theories is found.

description: We assess the impact of a Hausman pretest, applied to panel data, on a confidence interval for the slope, conditional on the observed values of the time-varying covariate. This assessment has the advantages that it (a) relates to the values of this covariate at hand, (b) is valid irrespective of how this covariate is generated, (c) uses finite sample results and (d) results in an assessment that is determined by the values of this covariate and only 2 unknown parameters. Our conditional analysis shows that the confidence interval constructed after a Hausman pretest should not be used.

Variability in the Colored and Fluorescent Dissolved Organic Matter with Salinity in the Neuse River Estuary
Creators: name: Dang, George T.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: The chromophoric and fluorescent dissolved organic matter (CDOM and FDOM, respectively) were examined in the Neuse River Estuary (NRE), North Carolina, USA, to assess the spatial and temporal variation in dissolved organic matter (DOM) quantity and quality. Trends of quantity and quality measurements were coupled to seasonal discharge and hydrologic mixing regimes. Differences between spectral measurements of DOM between low and high salinity datasets revealed differences in the CDOM and FDOM behavior along salinity gradients. Variability in the fluorescence character of DOM between the low and high salinity datasets revealed difficulties using fluorescence as a tracer for DOM along the salinity gradient in the NRE. Although fluorescing components with similar spectra were identified, differences in the fluorescing DOM components constrained a whole-system analysis of FDOM. While this study improved dissolved organic matter characterization of the NRE, it also revealed challenges with utilizing fluorescent properties in systems with large salinity gradients.

Examining the Relationship Between Athletics Spending and Directors’ Cup Standings
Creators: name: Freeman, Justin
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: A prevailing thought fueling the current athletics arms race is that increased spending is meant to generate and sustain competitive success. The purpose of this study was to determine whether a relationship exists between institutions' relative competitive success and: (a) overall total expenses, and total expenses per participant, (b) the number of teams sponsored, (c) total team operating expenses, and operating expenses per participant, (d) recruiting expenses and, (e) average coaches' salaries. EADA data and Directors' Cup standings were used for the years 2003-04 through 2010-11. Bivariate correlation and simple regression analyses found significant relationships between Directors' Cup points and each independent variable. Multiple regression analyses found Total Recruiting Expenses, Average Head Coaches' Salary, Total Number of Head Coaches, and Total Expenses per Participant to be significant predictors of Directors' Cup points. However, taking practical significance into account, careful consideration should be taken before making decisions based on these findings.

description: In an initial study, using a two time-point online survey, we provided evidence for a positive causal relationship between one’s concerns about catching COVID and the subsequent experiencing of COVID-associated symptoms (Rozenkrantz et al, in preparation). The best predictor for experiencing symptoms was one’s estimation of their symptoms’ severity had one caught COVID. This predictor, asked at T0, successfully predicted symptoms experience approximately 3 weeks later (T1), while accounting for symptoms at T0. Moreover, this predictor remained the best and most significant predictor for experiencing symptoms, even after accounting for demographics, state anxiety and actual risk of COVID prognosis (for example, belonging to a risk group as defined by the World Health Organization). Here, we aim to test this predictor and a further mediation we revealed in a new dataset.
Quantum triangular ice in the easy-axis ferromagnetic phase

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We use spin wave theory to investigate the ground state properties of the $Z_2$-invariant quantum XXZ model on the triangular lattice in the ferromagnetic phase. The Hamiltonian comprises nearest and next-nearest-neighbour Ising couplings, external magnetic fields, and a $Z_2$-invariant ferromagnetic coupling. We show that quantum fluctuations are suppressed in this system, hence linear spin wave theory gives reasonable estimates of the ground state thermodynamic properties. Our results show that, at half-filling (zero magnetic fields), the spontaneous breaking of $Z_2$ symmetry leads to a ferromagnetic phase whose energy spectrum is gapped at all excitations with a maxon dispersion at $\mathbf{k}=0$. This is in sharp contrast to rotational invariant systems with a vanishing phonon dispersion. We show that the $\mathbf{k}=0$ mode enhances the estimated values of the thermodynamic quantities. We obtain the trends of the particle density and the condensate fraction. The density of states and the dynamical structure factors exhibit fascinating peaks at unusual wave vectors, which should be of interest.

The highest pleasure of which woman's nature is capable: breastfeeding and the sentimental maternal ideal in America 1750-1860
Creators: name: Doyle, Nora
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: In the mid eighteenth century, Enlightenment debates about women's social role prompted a flurry of discussions about motherhood. Advice manuals, images of mothers, and women's personal writings highlighted breastfeeding as one of the most important maternal duties. This thesis argues that by the end of the eighteenth century advice manuals developed a new focus on the emotional and physical pleasure of breastfeeding. This rhetoric of pleasure contributed to the construction of a sentimental maternal ideal that remained the most important feminine script well into the nineteenth century, although the personal writings of mothers suggest that this ideal did not always reflect experience. At the same time, the erotic undertone in public discussions of breastfeeding suggested ambivalence toward maternal sexuality by both embracing and disguising women's pleasure. I suggest that the pleasure of breastfeeding offered possibilities for mediating and exploring sexuality within the context of marriage and socially sanctioned motherhood.

Development of Improved Dengue 2 Antigen Configurations for a Venezuelan Equine Encephalitis Virus Replicon Particle-Launched Dengue Vaccine
Creators: name: Webb, Drue Laine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Dengue has become one of the most important vector-borne diseases. There is currently no licensed dengue vaccine. The envelope glycoprotein is the major target of neutralizing antibodies. Researchers have tried to identify the most antigenic configuration of the envelope protein in different vaccine platforms. In this study, six dengue 2 E configurations, including full-length E, truncated forms of E and the domain III subunit, were expressed as antigen using the Venezuelan equine encephalitis virus replicon paricle system and characterized in vitro and in vivo. Each construct was immunogenic in mice; however, there was a correlation between protein secretion and neutralizing responses. Two truncated and soluble configurations of E encoding amino acid changes from the previously evaluated DEN2 prME-VRP sequence elicited significant neutralizing immune responses. These amino acid changes may be important in the structure of neutralizing epitopes or for proper folding, processing and secretion, leading to improved neutralizing antibody responses.

The Effects of a Single Bout of Resistance Exercise in Breast Cancer Survivors
Creators: name: Allen, Jacob Matthew
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This study examined the effect of resistance exercise (RE) on the acute responses of three inflammatory cytokines (Interleukin 6 [IL-6], Interleukin 10 [IL-10], Tumor Necrosis Factor-alpha [TNF-alpha] in breast cancer survivors. Breast cancer survivors (BCS) (n = 4) and healthy controls (C) (n=8) completed three sets of four exercises at 70% of one-repetition max. Blood samples were collected prior (Pre), immediately after (ImP), 2 hours after (2P) and 24 hours after (24P) exercise bout. No differences were observed between groups for each cytokine at each time point. However, the RE did cause a significant upregulation in IL-6 at 2P (p=0.027) and a significant downregulation of TNF-alpha at 24P in both groups (p=0.011). These findings suggest that no differences exist between BCS and C with regards to the RE induced inflammatory response, and that RE promotes an anti-inflammatory response into recovery, as evidenced by the reduction in TNF-alpha at 24P.

Numerical simulations as well as probabilistic methods are used to show the existence of critical hysteresis for all values of $c > 0$. This extends earlier results for $c=0$ and $c=1$ to the entire range $0 \le c \le 1$, and provides new insight in non-equilibrium critical phenomena.

description: We consider dynamically controllable periodic structures, called Raman induced gratings, in three- and four-level atomic media, resulting from Raman interaction in a standing-wave pump. These gratings are due to periodic spatial modulation of the Raman nonlinearity and fundamentally differ from the ones based on electromagnetically induced transparency. The transmission and reflection spectra of such gratings can be simultaneously amplified and controlled by varying the pump field intensity. It is shown that a transparent medium with periodic spatial modulation of the Raman gain can be opaque near the Raman resonance and yet at the same time it can be a non-linear amplifying mirror. We also show that spectral properties of the Raman induced grating can be controlled with the help of an additional weak control field.

Oppression in paradise: homosexuality and homophobia in Jamaica
Creators: name: Greene, Ryan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Widely seen as a laidback island paradise, Jamaica bears the distinction of being perhaps the most homophobic nation in the western hemisphere. In three articles, this master's thesis examines various aspects of Jamaican attitudes toward homosexuality. The first article discusses Jamaican homophobia in broad terms and examines the work of the country's lone gay-rights group. The second article is a snapshot of some Jamaicans' responses about homosexuality. The third article explores the underground gay party scene in Jamaica through the context of one such party. The thesis aims to explore this topic of Jamaican homophobia from new angles and to illuminate some of the challenges gay, lesbian, bisexual and transgender people face on the island nation.
Contested Terrain: Harki Collective Memory in France (2003-2008)
Creators: name: Sims, Laura Jeanne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: My thesis examines the creation, transmission, and contestation of the collective memory of harkis (Algerians who fought in the French Army in the Algerian War of Independence) and their descendants. It investigates how the harkis use various cultural carriers of memory (such as films and memoirs) and organizational carriers of memory (such as association websites) to communicate their memory to other members of their community and the rest of French society. Harki memoir writers and harkis writing on association websites share a general understanding of their history, but they emphasize different moments and offer contradictory interpretations of events, which often leads to conflicts within the community. Memoir writers, who are mainly daughters of harkis, construct a memory of victimhood that is highly personal and ambiguous. Sons of harkis writing on the association websites, however, promote a more unified and static version of the past that is essentially heroic.

description: As part of the Megamaser Cosmology Project (MCP), here we present a new geometric distance measurement to the megamaser galaxy NGC 5765b. Through a series of VLBI observations, we have confirmed the water masers trace a thin, sub-parsec Keplerian disk around the nucleus, implying an enclosed mass of 4.55 $\pm$ 0.40 $\times~10^{7}M_\odot$. Meanwhile, from single dish monitoring of the maser spectra over two years, we measured the secular drifts of maser features near the systemic velocity of the galaxy with rates between 0.5 and 1.2 km s$^{-1}$ yr$^{-1}$. Fitting a warped, thin disk model to these measurements, we determine a Hubble Constant $H_{0}$ of 66.0 $\pm$ 6.0 km s$^{-1}$ Mpc$^{-1}$ with the angular-diameter distance to NGC 5765b of 126.3 $\pm$ 11.6 Mpc. Apart from the distance measurement, we also investigate some physical properties related to the maser disk in NGC 5765b. The high-velocity features are spatially distributed into several clumps, which may indicate the existence of a spiral density wave associated with the accretion disk. For the red-shifted features, the envelope defined by the peak maser intensities increases with radius. The profile of the systemic masers in NGC 5765b is smooth and shows almost no structural changes over the two years of monitoring time, which differs from the more variable case of NGC 4258.

Theoretical study on density of microscopic states in configuration space via Random Matrix

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: In classical systems, our recent theoretical study provides new insight into how spatial constraint on the system connects with macroscopic properties, which lead to universal representation of equilibrium macroscopic physical property and structure in disordered states. These important characteristics rely on the fact that statistical interdependence for density of microscopic states (DOMS) in configuration space appears numerically vanished at thermodynamic limit for a wide class of spatial constraints, while such behavior of the DOMS is not quantitatively well-understood so far. The present study theoretically address this problem based on the Random Matrix with Gaussian Orthogonal Ensemble, where corresponding statistical independence is mathematically guaranteed. Using the generalized Ising model, we confirm that lower-order moment of density of eigenstates (DOE) of covariance matrix of DOMS shows asymptotic behavior to those for Random Matrix with increase of system size. This result supports our developed theoretical approach, where equilibrium macroscopic property in disordered states can be decomposed into individual contribtion from each generalized coordinate with the sufficiently high number of constituents in the given system, leading to representing equilibrium macroscopic properties by a few special microscopic states.

description: The discovery of graphene has ignited intensive investigation on two dimensional (2D) materials. Among them, transition metal dichalcogenide (TMDC), a typical representative, attracts much attention due to the excellent performance in field effect transistor (FET) related measurements and applications. Particularly, when TMDC eventually reaches few-layer dimension, a wide range of electronic and optical properties, in striking contrast to bulk samples, are detected. In this Letter, we synthesized single crystalline WS2 nanoflakes by physical vapor deposition (PVD) method and carried out a series of transport measurements of contact resistance and magnetoresistance. Focused ion beam (FIB) technology was applied to deposit Pt electrodes on WS2 flakes. Different from the electron beam lithography (EBL) fabricated electrodes, FIB-deposited leads exhibited ohmic contact, resolving the dilemma of Schottky barrier. Furthermore, a temperature-modulated negative-to-positive transition of magnetoresistance (MR) associated with a crossover of carrier type at similar temperature was demonstrated. Our work offers a pathway to optimize the contact for TMDC and reveals the magnetoresistance characteristics of WS2 flakes, which may stimulate further studies on TMDC and corresponding potential electronic and optoelectronic applications.
The costs and benefits of large scale solar photovoltaic power production in Abu Dhabi, UAE
Creators: name: Harder, Elizabeth Stewart
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: The potential for a 10 MW photovoltaic power plant in Abu Dhabi is examined in this paper, using RETScreen modeling software to predict energy production, financial feasibility and GHG emissions reductions. Initial results show a high energy production potential, generating 24 GWh and saving over 10,000 tons of GHG emissions annually, but a poor financial analysis yielding a net present value (NPV) of negative $51 million. Benefits of reducing GHG and air pollution emissions by replacing natural gas with PV generation are calculated to have a net present value of $44 million, with a large range of possible values. Results show that the high initial costs and low expected price for electricity generated are driving reasons why photovoltaic systems are not being implemented in Abu Dhabi. A feed-in-tariff rate of $0.16/kWh is recommended to make large scale PV systems profitable.

In the solid solution of Mg2Si1-xSnx, the Mg sublattice and Si/Sn sublattice are expected to undergo either tensile or compressive strain. Interestingly, both tensile strain of Mg2Si and compressive strain of Mg2Sn enhance the conduction band valley degeneracy or band convergence, which has been strongly speculated as the electronic origin of the enhanced Seebeck coefficient in the Mg2Si1-xSnx system. We also consider finite-temperature electronic band structures of these systems to account for high temperature effects. Our results clearly highlight and demonstrate the role of sublattice strain in the band valley degeneracy observed in Mg2Si1-xSnx .

The Abroad as Muse: Tradition, Perception, and Motivation in Expatriate Artist Narratives
Creators: name: Accardi, Cristin (Chloey)
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This paper explores the tradition of expatriate artist narratives - their themes, structure, presentation, and purpose served for artists and their created communities. Comparing oral narratives of international artists living in 2012 Berlin's Neukölln neighborhood with artists' published prose and memoir from pre-war Paris and colonial Tangier, a narrative formula is established. Adapting Charlotte Linde's coherence system model, narrative elements are understood as belonging to either the broad expatriate artist tradition, or the Neukölln neighborhood's unique ethos. Characterizing an artist's native culture, reasons for leaving, and motivations for selecting a specific community abroad, narratives establish difference between the renounced and the desired. Through depictions of a free, creative lifestyle narratives assert a shared set of values, and through constructions of fate and artistic flow, validate and motivate an expatriate's circumstance abroad. Expatriation symbolizes emb

description: Thermal conductance of metal contacts on transferred graphene (trG) could be significantly reduced from the intrinsic value of similar contacts on as-grown graphene (grG), due to additional resistance by increased roughness, residues, oxides and voids. In this paper, we compare the thermal conductance (G) of Al/trG/Cu interfaces with that of Al/grG/Cu interfaces to understand heat transfer across metal contacts on transferred graphene. Our samples are polycrystalline graphene grown on Cu foils by chemical vapor deposition (CVD) and CVD-grown graphene transferred to evaporated Cu thin films. We find that for the Al/grG/Cu interfaces of as-grown CVD graphene, G=31 MW m^{-2} K^{-1} at room temperature, two orders of magnitude lower than that of Al/Cu interfaces. For most as-transferred graphene on Cu films, G=20 MW m^{-2} K^{-1}, 35% lower than that of as-grown CVD graphene. We carefully rule out the contributions of residues, native oxides and interfaces roughness, and attribute the difference in the thermal conductance of as-grown and as-transferred CVD graphene to different degrees of conformity of graphene to the Cu substrates. We find that a contact area of 50% only reduces the thermal conductance by 35%, suggesting that a small amount of heat transfer occurs across voids at graphene interfaces. We successfully improve the conformity of the as-transferred graphene to the substrates by annealing the samples at 300°C, and thus enhance the thermal conductance of the transferred graphene to the intrinsic value. From the temperature dependence measurements of G of Al/trG/Cu and Al/grG/Cu interfaces, we also confirm that phonons are the dominant heat carries across the metal/graphene/metal interfaces despite a substantial carrier concentration of 3x10^{12} cm^{-2} induced in the graphene.

Molecular characterization of β2 adrenergic receptor haplotypes
Creators: name: Higgins, Thomas John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Adrenergic receptor β2 (ADRB2) is a primary target for epinephrine. It is critical in mediating physiological responses to environmental stressors and affects a complex array of psychological and physiological characteristics: including asthma, hypertension, and pain sensitivity. We searched the ADRB2 promoter region for transcriptional activator putative binding sites, which revealed CREB, p65, and C/EBP binding sites. We constructed a luciferase reporter vector containing three major polymorphic variant haplotypes of a 2.0 kb human ADRB2 promoter region, and transiently transected the constructs into liver, neuronal, and immune cell lines. We demonstrated; a) different levels of basal promoter activity related to three major human haplotypes; b) tissue specific regulation of ADRB2 promoter at the basal level and upon treatment; c) haplotypes exhibited similar response patterns, demonstrating haplotype-independent transcription regulation by C/EBP, NFκB, and cAMP. These results are the first to demonstrate haplotype-dependent regulation of ADRB2 by cAMP, NFκB, and C/EBP pathways.

description: We present Submillimeter Array (SMA) observations of the HCN\,(3--2) and HCO$^+$\,(3--2) molecular lines toward the W3(H$_2$O) and W3(OH) star-forming complexes. Infall and outflow motions in the W3(H$_2$O) have been characterized by observing HCN and HCO$^+$ transitions. High-velocity blue/red-shifted emission, tracing the outflow, show multiple knots, which might originate in episodic and precessing outflows. `Blue-peaked' line profiles indicate that gas is infalling onto the W3(H$_2$O) dust core. The measured large mass accretion rate, 2.3$\times$10$^{-3}$~M$_{\odot}$~yr$^{-1}$, together with the small free-fall time scale, 5$\times$10$^{3}$~yr, suggest W3(H$_2$O) is in an early evolutionary stage of the process of formation of high-mass stars. For the W3(OH), a two-layer model fit to the HCN and HCO$^+$ spectral lines and Spizter/IRAC images support that the W3(OH) H{\sc ii} region is expanding and interacting with the ambient gas, with the shocked neutral gas being expanding with an expansion timescale of 6.4$\times$10$^{3}$~yr. The observations suggest different kinematical timescales and dynamical states for the W3(H$_2$O) and W3(OH).

Year: 2007

description: Purpose: To (1) characterize epidemiological trends in anterior permanent tooth trauma (2) examine the relationship of crown fractures and root fractures to determine if crown fractures are protective against root fractures (3) determine the diagnostic value of obtaining three periapical radiographic projections to assess potential root fractures. Methods: Two dentists served as expert examiners for the radiographic assessments. Kappa statistics, Pearson's Chi-Square tests and logistic regression analyses were employed. Results: The final sample included 185 teeth. Expert examiners detected: 22 root fractures, 10% of the teeth exhibited root fractures when no crown fractures was documented, and 14% of the teeth had both crown fractures and root fractures as separate entities. Conclusions: Crown fractures were not protective against root fractures. As radiographic projections increased, root fractures were identified more often. Our data support obtaining multiple radiographic projections at different vertical angulations to rule out root fractures in children and adolescents.

description: Objectives: To identify differentially expressed genes and molecular pathways that modulate osseous healing around implants in patients with diabetes as compared to healthy individuals. Materials and Methods: 4 healthy subjects and 6 patients with type 2 diabetes that required implant placement were enrolled in the study. For each patient, two titanium test cylinders were placed in the mandible, and were removed at two and four weeks using a trephine drill. Bone biopsies were processed for RNA extraction. Whole transcriptome analysis was performed using Affymetrix (Affymatrix Inc, Santa Clara, CA) and confirmed with quantitative PCR using an array for human osteogenesis genes. Results: Analysis revealed that patients with T2DM presented downregulation of SPP1, BMPR1B, IGF-1; and an increased expression of SOST, and osteogenesis genes at 4 weeks as compared to healthy individuals. Conclusion: patients with T2DM presented with delayed osseous healing since we observed decreased expression of important genes involved in osseous healing, and increased expression of early transcription factors and important osteogenesis genes at later stages as compared to healthy individuals.
