Sticky tastes: the importance of cohort music preferences
Creators: name: Ritchey, Andrew Joseph
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Tastes for cultural products, including music, set up and reinforce boundaries for social interaction. This study tests the stickiness of musical tastes based on cohort relative to tastes based on age category. Using data from five waves of the Survey of Public Participation in the Arts, this paper shows that while cohort tastes may vary over time, they are much more consistent than age-based tastes. I argue for the possible importance of music to identity and suggest that lifelong cohort tastes are often established in adolescence and young adulthood.

description: In this article, we study the minimal degree [K(T):K] of a p-subgroup T <= E(\overline{K})_tors for an elliptic curve E/K defined over a number field K. Our results depend on the shape of the image of the p-adic Galois representation ρ_{E,p^infty}:Gal_K-->GL(2,Z_p). However, we are able to show that there are certain uniform bounds for the minimal degree of definition of T. When the results are applied to K=Q and p=2, we obtain a divisibility condition on the minimal degree of definition of any subgroup of E[2^n] that is best possible.

description: The discrimination and simplicity of features are very important for effective and efficient pedestrian detection. However, most state-of-the-art methods are unable to achieve good tradeoff between accuracy and efficiency. Inspired by some simple inherent attributes of pedestrians (i.e., appearance constancy and shape symmetry), we propose two new types of non-neighboring features (NNF): side-inner difference features (SIDF) and symmetrical similarity features (SSF). SIDF can characterize the difference between the background and pedestrian and the difference between the pedestrian contour and its inner part. SSF can capture the symmetrical similarity of pedestrian shape. However, it's difficult for neighboring features to have such above characterization abilities. Finally, we propose to combine both non-neighboring and neighboring features for pedestrian detection. It's found that non-neighboring features can further decrease the average miss rate by 4.44%. Experimental results on INRIA and Caltech pedestrian datasets demonstrate the effectiveness and efficiency of the proposed method. Compared to the state-of-the-art methods without using CNN, our method achieves the best detection performance on Caltech, outperforming the second best method (i.e., Checkboards) by 1.63%.

Andrew J. Goodpaster Jr., 1915-1947: The Making of a Political-Military Officer
Creators: name: Grover, Josiah T.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: General Andrew J. Goodpaster served in the US Army for thirty-nine years and participated in many of the most important events of the Cold War, from planning nuclear strategy in the Pentagon to serving as President Eisenhower's national security aide, then as director of the Joint Staff, the assistant commander of U.S. forces in Vietnam, the Supreme Allied Commander, Europe, and finally as the superintendent at West Point. In each of these assignments Goodpaster participated in major Cold War events and the simultaneous development of the American national security state. The emergence of the national security state and the changes in political-military affairs that accompanied it changed both the character and the role of the military profession in the United States in substantial ways. Andrew Goodpaster's career exemplified that change. This thesis examines Goodpaster's early life and career from 1915-1947 to discover the foundations of his later, more prominent career.

description: Effective Field Theories offer a consistent bottom-up approach to parametrise small deviations from Standard Model predictions. In this work we report on the application of the Effective Field Theory to shed light on effects from high-scale physics beyond the Standard Model on the Higgs transverse-momentum spectrum. The Standard Model prediction for the transverse-momentum distribution in Higgs boson production through gluon fusion is augmented by three new dimension-six operators, implying the modification of the top and bottom Yukawa couplings, and the inclusion of a point-like Higgs-gluon coupling. We present resummed transverse-momentum spectra including these operators at NLO+NLL accuracy and study their effects on the shape of the distribution. The proper parametrization of such effects becomes increasingly important for experimental analyses in Run II of the LHC.

description: Using the descent spectral sequence for a Galois extension of ring spectra, we compute the Picard group of the higher real $K$-theory spectra of Hopkins and Miller at height $n=p-1$, for $p$ an odd prime. More generally, we determine the Picard groups of the homotopy fixed points spectra $E_n^{hG}$, where $E_n$ is Lubin-Tate $E$-theory at the prime $p$ and height $n=p-1$, and $G$ is any finite subgroup of the extended Morava stabilizer group. We find that these Picard groups are always cyclic, generated by the suspension.

Past substance use disorder is associated with a more rapid transition from goal-directed to habitual responding
Creators: name: McKim, Theresa
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: The hallmark behavior of addiction is continued drug use despite serious negative consequences of such use. Animal research suggests that chronic drug use promotes an overreliance on habit-based behaviors at the expense of flexible goal-directed actions. However, an imbalance in these behavioral control systems has not been experimentally investigated in humans with a drug use history who are currently abstinent. The aim of this research study was to assess stimulus-response (S-R) learning and replacement to evaluate habitual versus goal-directed response selection in individuals with a substance use disorder (SUD) history. A total of 22 individuals with an SUD history and 30 healthy control subjects were tested in an S-R learning task to measure group differences in learning over time during pre-and post-devaluation phases of the task. Additionally, we examined perseverative responding after devaluation to assess the ability to adapt both well-established and recently learned S-R associations. We used multilevel modeling to analyze differences between groups in learning behavior over time. The results of this study provide evidence for habitual responding in the SUD history group relative to the control group. These habit-based behaviors were reflected by an increase in perseverative responding that persisted over time in the SUD history group. This is the first human study to provide evidence for an imbalance between habitual and goal-directed control in a learning task in which SUD individuals are not globally impaired, but where deficits in response selection are selective to inflexible habit-based responding.

description: Superconductivity is commonly described as a macroscopic quantum phenomenon. However, it arises from microscopic mechanisms occurring at the nanometer scale as illustrated, for example, by the non-trivial pairing in unconventional superconductors. More recently, also local interactions with superconductors in the context of Majorana fermions became of interest. A very direct way to study the atomic scale properties of superconductors is given by the combination of the Josephson effect with scanning tunneling microscopy (STM), also referred to as JSTM. Here, the critical Josephson current serves as a direct local probe of the superconducting ground state and may reveal valuable information that is often inaccessible when studying quasi-particle excitation spectra. We show that we can extract local values of the critical Josephson current from JSTM measurements in the dynamical Coulomb blockade regime. Furthermore, we experimentally determine the regime of sequential Cooper pair tunneling, which is in accordance to theoretical predictions. Our study presents new insights on the tunneling mechanisms in Josephson junctions and lays the basis for the implementation of JSTM as a versatile probe for superconductivity.
Spatially resolved eastward winds and rotation of HD 189733b

description: We measure wind velocities on opposite sides of the hot Jupiter HD$\,$189733b by modeling sodium absorption in high-resolution HARPS transmission spectra. Our model implicitly accounts for the Rossiter-McLaughlin effect, which we show can explain the high wind velocities suggested by previous studies. Our results reveal a strong eastward motion of the atmosphere of HD$\,$189733b, with a redshift of $2.3^{+1.3}_{-1.5}$$\,$km$\,$s$^{-1}$ on the leading limb of the planet and a blueshift of $5.3^{+1.0}_{-1.4}$$\,$km$\,$s$^{-1}$ on the trailing limb. These velocities can be understood as a combination of tidally locked planetary rotation and an eastward equatorial jet; closely matching the predictions of atmospheric circulation models. Our results show that the sodium absorption of HD$\,$189733b is intrinsically velocity broadened and so previous studies of the average transmission spectrum are likely to have overestimated the role of pressure and thermal broadening.

description: Let $(\mathcal X, d, μ)$ be a complete RD-space. Let $ρ$ be an admissible function on $\mathcal X$, which means that $ρ$ is a positive function on $\mathcal X$ and there exist positive constants $C_0$ and $k_0$ such that, for any $x,y\in \mathcal X$, $$ρ(y)\leq C_0 [ρ(x)]^{1/(1+k_0)} [ρ(x)+d(x,y)]^{k_0/(1+k_0)}.$$ In this paper, we define a space $VMO_ρ(\mathcal X)$ and show that it is the predual of the localized Hardy space $H^1_ρ(\mathcal X)$ introduced by Yang and Zhou \cite{YZ}. Then we prove a version of the classical theorem of Jones and Journé \cite{JJ} on weak$^*$-convergence in $H^1_ρ(\mathcal X)$. As an application, we give an atomic characterization of $H^1_ρ(\mathcal X)$.
Nasal coraticulation in the french vowel /i/: a phonetic and phonological study
Creators: name: Spears, Abby
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: In this paper, I use acoustic phonetic data to examine the phenomenon of nasal coarticulation in French. Previous work describes French as a language with very little vowel-nasal (VN) coarticulation, presumably due to the oral/nasal contrast in vowels (Cohn 1990). However, I found that the high vowel /i/, which has no nasal counterpart in French, exhibits a high degree of coarticulation This finding supports the proposal that contrast and coarticulation are inversely correlated (Manuel 1990), adding the insight that this correlation is observable even within a language. Based on this finding and a typological survey of VN coarticulation, I propose an underspecification account in an Optimality Theoretic framework to capture the patterns of VN coarticulation. In this OT account, the interaction of markedness constraints driving orality and minimizing effort and a faithfulness constraint protecting the feature [+ nasal] provides an explanation for the French data and produces the attested typology.

description: La promozione della salute nella società e nelle istituzioni non può prescindere dal ruolo fondamentale delle Università e, in particolare, all'interno di esse, dalla funzione dei Dipartimenti e dei corsi di studio. Proprio nello svolgimento di queste funzioni gli Atenei e i Dipartimenti traggono la loro legittimità sociale e vedono riconosciute le loro funzioni scientifiche oltre che, il loro essere uno tra i presidi della sanità pubblica. Il diffondersi di una nuova, emergente, domanda di promozione della salute attraverso le attività motorie e lo sport e di una più ampia aspettativa rivolta ai servizi sanitari non poteva, infatti, non coinvolgere anche i sistemi e i percorsi formativi curriculari ed extracurriculari. I curricula dei corsi di studio si sono evoluti sostanzialmente nella direzione di un percorso che accompagni ogni Studente a sviluppare stili di vita corretti, i cui obiettivi formativi centrali sono identificabili nell’approccio olistico, nello sviluppo di capacità di comunicazione e alla collaborazione con altre discipline impegnate nella formazione della comunità e nell'attenzione alla dimensione socioculturale. In questo senso è di centrale importanza che le istituzioni universitarie si impegnino nello sviluppo e nell’espansione di una concreta collaborazione tra istituzioni diverse.

The House in Iron Age Italian Thought

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Hut urns, miniaturized huts functioning as cinerary vessels, are found in graves from Etruria and Latium dating to the Early Iron Age. I examine four historical approaches to the study of hut urns: (1) the method of using hut urns as physical models for huts, (2) comparisons between Italian hut urns and Northern European house urns, (3) comparisons between hut urns and later Etruscan tombs, and (4) the examination of hut urns within the funerary context to understand social structures of the Italian Early Iron Age. A more holistic approach to studying hut urns demonstrates that Iron Age Italians imbued their huts with social significance and that the huts were used to create and express elite male social status. It is because of this social significance that the miniaturized huts were used in the funerary context.

description: The electronic structure of SrTiO3 and SrHfO3 (001) surfaces with oxygen vacancies is studied by means of first-principles calculations. We reveal how oxygen vacancies within the first atomic layer of the SrTiO3 surface (i) induce a large antiferrodistortive motion of the oxygen octahedra at the surface, (ii) drive localized magnetic moments on the Ti-3d orbitals close to the vacancies and (iii) form a two-dimensional electron gas localized within the first layers. The analysis of the spin-texture of this system exhibits a splitting of the energy bands according to the Zeeman interaction, lowering of the Ti-3dxy level in comparison with dxz and dyz and also an in-plane precession of the spins. No Rashba-like splitting for the ground state neither for ab-initio molecular dynamics trajectory at 400K is recognized as suggested recently by A. F. Santander-Syro et al. [1]. Instead, a sizeable Rashba-like splitting is observed when the Ti atom is replaced by a heavier Hf atom with a much larger spin-orbit interaction. However, we observe the disappearance of the magnetism and the surface two dimensional electron gas when full structural optimization of the SrHfO3 surface is performed. Our results uncover the sensitive interplay of spin-orbit coupling, atomic relaxations and magnetism when tuning these Sr-based perovskites.

description: Imaging Air Cherenkov Telescopes (IACTs) detect very high energetic (VHE) gamma rays. They observe the Cherenkov light emitted in electromagnetic shower cascades that gamma rays induce in the atmosphere. A precise reconstruction of the primary photon energy and the source flux depends heavily on accurate Monte Carlo (MC) simulations of the shower propagation and the detector response, and therefore also on adequate assumptions about the atmosphere at the site and time of a measurement. Here, we present the results of an extensive validation of the MC simulations for an analysis chain of the H.E.S.S. experiment with special focus on the recently installed FlashCam camera on the large 28 m telescope. One goal of this work was to create a flexible and easy-to-use framework to facilitate the detailed validation of MC simulations also for past and future phases of the H.E.S.S. experiment. Guided by the underlying physics, the detector simulation and the atmospheric transmission profiles were gradually improved until low level parameters such as cosmic ray (CR) trigger rates matched within a few percent between simulations and observational data. This led to instrument response functions (IRFs) with which the analysis of current H.E.S.S. data can ultimately be carried out within percent accuracy, substantially improving earlier simulations.

description: We propose an application-layer forward error correction (AL-FEC) code rate allocation scheme to maximize the quality of experience (QoE) of a video multicast. The allocation dynamically assigns multicast clients to the quality layers of a scalable video bitstream, based on their heterogeneous channel qualities and video playback capabilities. Normalized mean opinion score (NMOS) is employed to value the client's quality of experience across various possible adaptations of a multilayer video, coded using mixed spatial-temporal-amplitude scalability. The scheme provides assurance of reception of the video layers using fountain coding and effectively allocates coding rates across the layers to maximize a multicast utility measure. An advantageous feature of the proposed scheme is that the complexity of the optimization is independent of the number of clients. Additionally, a convex formulation is proposed that attains close to the best performance and offers a reliable alternative when further reduction in computational complexity is desired. The optimization is extended to perform suppression of QoE fluctuations for clients with marginal channel qualities. The scheme offers a means to trade-off service utility for the entire multicast group and clients with the worst channels. According to the simulation results, the proposed optimization framework is robust against source rate variations and limited amount of client feedback.

Conflict in Northern Ireland: Through the Lens of Social Identity Theory and Social Dominance Theory
Creators: name: Senholzi, Keith B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Complexity and Multiplicity of Historical Underpinnings
The history of Northern Ireland is one rife with identity conflict, stemming from
centuries ago, continuing on into the late 21st century. The conflict can be understood in
broad strokes as being between two main groups. The first group is the unionists, who
comprise roughly sixty per cent of the population of Northern Ireland, tend to see
themselves as British, are predominately Protestant, and want the northern area of the
island to remain part of the United Kingdom. The second group in the midst of the
conflict is the nationalists, who make up an increasing proportion of the population
(roughly forty per cent), tend to see themselves as Irish, are predominately Catholic, and
wish to be a part of a united Ireland (Dixon, 2001, p. 2). In effect, Northern Ireland can
be observed as a place where the British and Irish nations coincide; the resulting conationals,
British unionists and Irish nationalists, aspire to be a component of two distinct
states (p. 2). Generally speaking, the conflict lies in the sovereignty of the state, and the
two aforementioned warring factions hold intensely differing views on the future of a
divided nation. Despite the seemingly binary conflict that has ensued in the region, the
complex history of Northern Ireland is difficult to map out, given the role of overlapping
identities at bay, which will be discussed toward the close of this article. Nevertheless,
the following article will attempt to elucidate the dispute through the application of the
principal social psychological theories that suit the subject.

description: The implementation of a Cloud Radio Access Network (C-RAN) with Full Dimensional (FD)-MIMO is faced with the challenge of controlling the fronthaul overhead for the transmission of baseband signals as the number of horizontal and vertical antennas grows larger. This work proposes to leverage the special low-rank structure of FD-MIMO channel, which is characterized by a time-invariant elevation component and a time-varying azimuth component, by means of a layered precoding approach, so as to reduce the fronthaul overhead. According to this scheme, separate precoding matrices are applied for the azimuth and elevation channel components, with different rates of adaptation to the channel variations and correspondingly different impacts on the fronthaul capacity. Moreover, we consider two different Central Unit (CU) - Radio Unit (RU) functional splits at the physical layer, namely the conventional C-RAN implementation and an alternative one in which coding and precoding are performed at the RUs. Via numerical results, it is shown that the layered schemes significantly outperform conventional non-layered schemes, especially in the regime of low fronthaul capacity and large number of vertical antennas.

description: We report the continuous and partially nondestructive measurement of optical photons. For a weak light pulse traveling through a slow-light optical medium (signal), the associated atomic-excitation component is detected by another light beam (probe) with the aid of an optical cavity. We observe strong correlations of $g^{(2)}_{sp}=4.4(5)$ between the transmitted signal and probe photons. The observed (intrinsic) conditional nondestructive quantum efficiency ranges between 13% and 1% (65% and 5%) for a signal transmission range of 2% to 35%, at a typical time resolution of 2.5 $μ$s. The maximal observed (intrinsic) device nondestructive quantum efficiency, defined as the product of the conditional nondestructive quantum efficiency and the signal transmission, is 0.5% (2.4%). The normalized cross-correlation function violates the Cauchy-Schwarz inequality, confirming the non-classical character of the correlations.
Memory and Myth-Making: Post-Emancipation Literary Portrayals of Peasants in Russia and Freedmen in the American South
Creators: name: Bellows, Amanda Brickell
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This paper examines the different relationships that emerged from ostensibly parallel shifts in relative power after the abolition of serfdom in Russia and slavery in the United States. As Russian and Southern elites grappled with the political, economic, and social changes catalyzed by the elimination of these entrenched institutions, they presented and promoted divergent portrayals of the former serfs and slaves in fictional literature; these depictions are encompassed within the South's Lost Cause myth and Russia's Peasant myth. The emergence of disparate myths indicates that the post-emancipation power relations that developed between the masters and their former bondsmen in each region differed radically. More broadly, this comparison explores the causal processes that lead to the creation of myths, the function of myths in societies, and the ways in which changing political and economic factors shape the power relationships between individuals.

Traumatic Dental Injuries in Preschool-Age Children: Prevalence and Risk Factors
Creators: name: Born, Catherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Purpose: This study examined the prevalence, socio-demographic correlates, and clinical predictors of traumatic dental injuries (TDIs) in the primary dentition among a community-based sample of preschool-age children.
      Methods: The sample comprised 1,546 preschool-age children [mean age 49 (range: 24-71) months] in Early Head Start and Head Start programs in North Carolina, enrolled in the Zero-Out Early Childhood Caries (ZOE) study. Information on socio-demographic, extraoral, and intraoral characteristics was collected and analyzed with bivariate and multivariate methods, including logistic regression modeling and marginal effects estimation.
      Results: The prevalence of dental trauma was 47% and 8% of TDI cases were “severe”, defined as pulp exposure, tooth displacement, discolored or necrotic tooth, or tooth loss. In bivariate analyses, overjet and lip incompetence were significantly associated with TDI, whereas age, body mass index, and canine occlusion showed weaker positive associations. Overjet remained positively associated with severe trauma in multivariate analysis: OR=1.3 (95% CI: 1.2-1.5), corresponding to an absolute 1.0% (95% CI: 0.6-1.5) increase in the likelihood of severe trauma, per millimeter of overjet.
      Conclusions: Overjet is a strong risk factor for TDIs in the primary dentition. Incorporating and operationalizing this information may help traumatic dental injury prevention and related anticipatory guidance for families of preschool-age children.

Implicit Negativity, Discrete Emotions and Behaviors - Neutral Vignette Only (Pilot)

description: In the current pilot study, our aim is to identify suitable control emotion items, against which to compare activated emotion items in future studies. Participants will (1) read a NEUTRAL ARNOLD vignettes [designed to activate no specific negative emotion], (2) complete non-specific emotion items with regards to Arnold (e.g., "cold", "unfavorable", "bad"), and (3) complete a single-target IAT (ST-IAT) to measure IMPLCIT NEGATIVITY towards Arnold. Our hypothesis is that implicit negativity (IAT) will be significantly correlated with explicit, non-specific negativity. If we observe this pattern, we can be confident that these control items are capturing some non-specific negativity (against which to compare IAT's relationship with specific, activated negative emotions in future studies).

description: Superluminous supernovae (SLSNe) are a rare class of stellar explosions with luminosities ~10-100 times greater than ordinary core-collapse supernovae. One popular model to explain the enhanced optical output of hydrogen-poor (Type I) SLSNe invokes energy injection from a rapidly spinning magnetar. A prediction in this case is that high-energy gamma rays, generated in the wind nebula of the magnetar, could escape through the expanding supernova ejecta at late times (months or more after optical peak). This paper presents a search for gamma-ray emission in the broad energy band from 100 MeV to 30 TeV from two Type I SLSNe, SN2015bn, and SN2017egm, using observations from Fermi-LAT and VERITAS. Although no gamma-ray emission was detected from either source, the derived upper limits approach the putative magnetar's spin-down luminosity. Prospects are explored for detecting very-high-energy (VHE; 100 GeV - 100 TeV) emission from SLSNe-I with existing and planned facilities such as VERITAS and CTA.

description: We investigate electron transport through the interface between a niobium superconductor and the edge of a two-dimensional semimetal, realized in a 20~nm wide HgTe quantum well. Experimentally, we observe that typical behavior of a single Andreev contact is complicated by both a pronounced zero-bias resistance anomaly and shallow subgap resistance oscillations with $1/n$ periodicity. These results are demonstrated to be independent of the superconducting material and should be regarded as specific to a 2D semimetal in a proximity with a superconductor. We interpret these effects to originate from the Andreev-like correlated process at the edge of a two-dimensional semimetal.
