Writing maroon culture into nature: on the agency of colonial representations of black and green in Suriname
Creators: name: Kemper, Rudo
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: In this master's thesis, I analyze travel writing about Suriname, from early European colonization until the mid-20th century, to understand how the country's maroon populations were gradually imagined as belonging to the landscape of the rainforest interior. I argue that Suriname travelogues and similar narratives across this time period index and reproduce a colonial gaze of maroons as a natural (and therefore non-historical) component of the rainforest ontology. I trace these representations through the historical contexts and networks in which these travelogues circulate, drawing attention to sedimented narrative tropes about the rainforest and maroons which persevere throughout. Additionally, I argue that representations of maroons-in-nature play important roles as actants in present-day assemblages and networks. My goal in doing so is to demonstrate that post-structural methodologies such as genealogy or discourse analysis can be useful in a `flat ontologies' political ecology framework, despite philosophical differences between the two movements of thought.

description: It has been shown in the last few years that 3-form fields present viable cosmological solutions for inflation and dark energy with particular observable signatures distinct from those of canonical single scalar field inflation. The aim of this work is to explore the dynamics of a single 3-form in five dimensional Randall-Sundrum II braneworld scenario, in which a 3-form is confined to the brane and only gravity propagates in the bulk. We compare the solutions with the standard four dimensional case already studied in the literature. In particular, we evaluate how the spectral index and the ratio of tensor to scalar perturbations are influenced by the presence of the bulk and put constraints on the parameters of the models in the light of the recent Planck 2015 data.

Forming family in the European Union: new social risks and welfare responses
Creators: name: Small, Starr
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Social transformations have brought new risks for family formation which national welfare states have tried to address with varied success. Analyzing Spain and Sweden's historical legacies, this essay argues that they have played a determining role in their national welfare states' ability to adapt to the new social risks. The relative success of Sweden and failure of Spain to resolve the conflicts facing family formation underscores the diversity of national welfare policy toward families within the European Union. Facing this national diversity, this essay examines how the EU develops coordination and convergence strategies for its member-states in female employment, reconciliation, and gender equality. Although less clear in Sweden, a moderate "Europeanization effect" of family policy appears to be emerging in Spain. This implies that as national welfare states attempt to assimilate EU family policy targets, the EU gains greater potential to influence social policy.

description: We present a combined analytical approach and numerical study on the stability of a ring bound to an annular elastic substrate, which contains a circular cavity. The system is loaded by depressurizing the inner cavity. The ring is modeled as an Euler-Bernoulli beam and its equilibrium equations are derived from the mechanical energy which takes into account both stretching and bending contributions. The curvature of the substrate is considered explicitly to model the work done by its reaction force on the ring. We distinguish two different instabilities: periodic wrinkling of the ring or global buckling of the structure. Our model provides an expression for the critical pressure, as well as a phase diagram that rationalizes the transition between instability modes. Towards assessing the role of curvature, we compare our results for the critical stress and the wrinkling wavelength to their planar counterparts. We show that the critical stress is insensitive to the curvature of the substrate, while the wavelength is only affected due to the permissible discrete values of the azimuthal wavenumber imposed by the geometry of the problem. Throughout, we contrast our analytical predictions against finite element simulations.

Seismic stratigraphic record of West Antarctic ice sheet fluctuations within the eastern basin of the Ross Sea, Antarctica
Creators: name: Loth, Audrey Susan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Using geophysical data collected aboard the R/V Nathaniel B. Palmer during the austral summer of 2004 the stratigraphy of the up-dip portion of the Antarctic margin was studied. Analysis of up-dip SCS profiles illustrated an incomplete glacial record with multiple thin, polar Plio-Pleistocene sequences reflecting the presence of Northern Hemisphere ice, and fewer, thick Early Miocene sequences indicating perhaps a subpolar basal regime. Across the shelf of the Eastern Basin, the majority of the sequences terminate mid-shelf suggesting that not all ice sheet events are the same magnitude, which may be a function of climate change or autogenic ice sheet fluctuations. Through quantitative analysis the up-dip stratigraphy of the Eastern Basin was shown to be highly heterogeneous. This work has provided a more robust illustration of the complexity of glacial stratigraphy in the up-dip setting, and it is possible to see a reflection of changing climate preserved in the seismic signature of the NBP 0306 profiles.

Super-Linear Gate and Super-Quadratic Wire Lower Bounds for Depth-Two and Depth-Three Threshold Circuits

description: In order to formally understand the power of neural computing, we first need to crack the frontier of threshold circuits with two and three layers, a regime that has been surprisingly intractable to analyze. We prove the first super-linear gate lower bounds and the first super-quadratic wire lower bounds for depth-two linear threshold circuits with arbitrary weights, and depth-three majority circuits computing an explicit function. $\bullet$ We prove that for all $ε\gg \sqrt{\log(n)/n}$, the linear-time computable Andreev's function cannot be computed on a $(1/2+ε)$-fraction of $n$-bit inputs by depth-two linear threshold circuits of $o(ε^3 n^{3/2}/\log^3 n)$ gates, nor can it be computed with $o(ε^{3} n^{5/2}/\log^{7/2} n)$ wires. This establishes an average-case ``size hierarchy'' for threshold circuits, as Andreev's function is computable by uniform depth-two circuits of $o(n^3)$ linear threshold gates, and by uniform depth-three circuits of $O(n)$ majority gates. $\bullet$ We present a new function in $P$ based on small-biased sets, which we prove cannot be computed by a majority vote of depth-two linear threshold circuits with $o(n^{3/2}/\log^3 n)$ gates, nor with $o(n^{5/2}/\log^{7/2}n)$ wires. $\bullet$ We give tight average-case (gate and wire) complexity results for computing PARITY with depth-two threshold circuits; the answer turns out to be the same as for depth-two majority circuits. The key is a new random restriction lemma for linear threshold functions. Our main analytical tool is the Littlewood-Offord Lemma from additive combinatorics.

description: We analyse the quantum behaviour of the "Little Sibling" of the Big Rip singularity (LSBR) [1]. The quantisation is carried within the geometrodynamical approach given by the Wheeler--DeWitt (WDW) equation. The classical model is based on a Friedmann--Lemaître--Robertson--Walker Universe filled by a perfect fluid that can be mapped to a scalar field with phantom character. We analyse the WDW equation in two setups. In the first step, we consider the scale factor as the single degree of freedom, which from a classical perspective parametrises both the geometry and the matter content given by the perfect fluid. We then solve the WDW equation within a WKB approximation, for two factor ordering choices. On the second approach, we consider the WDW equation with two degrees of freedom: the scale factor and a scalar field. We solve the WDW equation, with the Laplace--Beltrami factor-ordering, using a Born--Oppenheimer approximation. In both approaches, we impose the DeWitt (DW) condition as a potential criterion for singularity avoidance. We conclude that in all the cases analysed the DW condition can be verified, which might be an indication that the LSBR can be avoided or smoothed in the quantum approach.

description: Introduction: The hallmark sign of knee osteoarthritis (OA) is cartilage damage. Patients with knee OA present impulse loading, co-activation of knee musculature, and somatosensory deficits have been. These characteristics could be precursors rather than disease outcomes. Purpose: to evaluate associations between vibratory sensation (VPT), quadriceps and hamstring co-activation, and percent change of cartilage cross-sectional area (CSA) in healthy population. Methods: VPT was measured, participants performed walking trial where co-activation was measured, and pre/post ultrasound cartilage images were collected. Pearson product (r) determined associations between VPT, co-activaiton indices, and change in CSA.  Results: 31 participants (age=22(2.5)years, height=1.71(0.15)m weight=74.9(11.8)kg) completed this study. Significant associations between medial and composite co-activation index and change in CSA (r=0.031, p=0.009), between lateral malleolus VPT and co-activation indices laterally during PRE-phase of gait, and composite during LA (r=-0.443,p=0.014 and r=0.415, p=0.023) were found. Discussion: Greater co-activation during gait may be associated with changes in knee cartilage.

description: We consider a family of percolation models in which geometry and connectivity are defined by two independent random processes. Such models merge characteristics of discrete and continuous percolation. We develop an algorithm allowing effective computation of both universal and modelspecific percolation quantities in the case when both random processes are Poisson processes. The algorithm extends percolation algorithm by Newman and Ziff (M.E.J. Newman and R.M. Ziff, Phys Rev E, 64(1):016706, 2001) to handle inhomogeneous lattices. In particular, we use the proposed method to compute critical exponents and cluster density distribution in two and three dimensions for the model of parallel random tubes connected randomly by bonds, which models the connectivity properties of activated carbon.

description: We have discovered 11 ultra-faint ($r\lesssim 22.1$) low surface brightness (LSB, central surface brightness $23\lesssim μ_r\lesssim 26$) dwarf galaxy candidates in one deep Virgo field of just $576$ arcmin$^2$ obtained by the Large Binocular Camera (LBC) at the Large Binocular Telescope (LBT). Their association with the Virgo cluster is supported by their distinct position in the central surface brightness - total magnitude plane with respect to the background galaxies of similar total magnitude. They have typical absolute magnitudes and scale sizes, if at the distance of Virgo, in the range $-13\lesssim M_r\lesssim -9$ and $250\lesssim r_s\lesssim 850$ pc, respectively. Their colors are consistent with a gradually declining star formation history with a specific star formation rate of the order of $10^{-11}$ yr$^{-1}$, i.e. 10 times lower than that of main sequence star forming galaxies. They are older than the cluster formation age and appear regular in morphology. They represent the faintest extremes of the population of low luminosity LSB dwarfs that has been recently detected in wider surveys of the Virgo cluster. Thanks to the depth of our observations we are able to extend the Virgo luminosity function down to $M_r\sim -9.3$ (corresponding to total masses $M\sim 10^7$ M$_{\odot}$), finding an average faint-end slope $α\simeq -1.4$. This relatively steep slope puts interesting constraints on the nature of the Dark Matter and in particular on warm Dark Matter (WDM) often invoked to solve the overprediction of the dwarf number density by the standard CDM scenario. We derive a lower limit on the WDM particle mass $>1.5$ keV.

Hydration Status, Salivary Biomarkers of Stress, Body Composition, and Performance in Response to a 4-Week Pre-Season Training Cycle in Division 1 Basketball Players: An Observational Study
Creators: name: Ayscue, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This observational study profiled various physiological parameters in a group of fourteen elite level Division-I male basketball players during four-weeks pre-season strength and conditioning training. Hydration status, hormonal changes (specifically testosterone and cortisol), body composition, training load, and performance (measured by a peak velocity test) variables were observed. The potential relationship between changes in hydration status, training volume and physical performance were observed. In addition, the relationship between individual player’s hormonal responses and performance showed weak but potentially clinically relevant associations mainly for testosterone. Overall, trends of change in study variables during the pre-season strength and conditioning training program were observed. More specifically, hydration and testosterone fluctuations may have been influenced by training load changes, in turn influencing the performance measure used in this study. Future investigations exploring these relationships are warranted, so that information may be provided to coaches to better gauge training load increases to maximize training response.

description: We introduce K3 transitions as a geometric approach to studying canonical 3-folds. These transitions link different deformation classes of canonical 3-folds via a combination of birational contractions and smoothings. As applications, we investigate some basic properties of the web of canonical 3-folds in small codimension and give an interesting example of a singularity in codimension 4 with obstructed smoothings, similar to the famous example of the affine cone over a degree 6 del Pezzo surface.

`Ferroelectric' Metals Reexamined: Fundamental Mechanisms and Design Considerations for New Materials

Publisher: name: arXiv
Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The recent observation of a ferroelectric-like structural transition in metallic LiOsO$_3$ has generated a flurry of interest in the properties of polar metals. Such materials are thought to be rare because free electrons screen out the long-range electrostatic forces that favor a polar structure with a dipole moment in every unit cell. In this work, we question whether long-range electrostatic forces are always the most important ingredient in driving polar distortions. We use crystal chemical models, in combination with first-principles Density Functional Theory calculations, to explore the mechanisms of inversion-symmetry breaking in LiOsO$_3$ and both insulating and electron-doped ATiO$_3$ perovskites, A = Ba, Sr, Ca. Although electrostatic forces do play a significant role in driving the polar instability of BaTiO$_3$ (which is suppressed under electron doping), the polar phases of CaTiO$_3$ and LiOsO$_3$ emerge through a mechanism driven by local bonding preferences and this mechanism is `resistant' to the presence of charge carriers. Hence, our results suggest that there is no fundamental incompatibility between metallicity and polar distortions. We use the insights gained from our calculations to suggest design principles for new polar metals and promising avenues for further research.

description: We consider a simple model of communities interacting via bilinear terms. After analyzing the thermal equilibrium case, which can be described by an Hamiltonian, we introduce the dynamics that, for Ising-like variables, reduces to a Glauber-like dynamics. We analyze and compare four different versions of the dynamics: flow (differential equations), map (discrete-time dynamics), local-time update flow, and local-time update map. The presence of only bilinear interactions prevent the flow cases to develop any dynamical instability, the system converging always to the thermal equilibrium. The situation is different for the map when unfriendly couplings are involved, where period-two oscillations arise. In the case of the map with local-time updates, oscillations of any period and chaos can arise as a consequence of the reciprocal "tension" accumulated among the communities during their sleeping time interval. The resulting chaos can be of two kinds: true chaos characterized by positive Lyapunov exponent and bifurcation cascades, or marginal chaos characterized by zero Lyapunov exponent and critical continuous regions.

description: Purpose: To assess North Carolina dental hygiene (DH), nursing students’ and practitioners’ knowledge, opinions, and behaviors regarding e-cigarettes. Methods: A convenience sample of DH students, registered dental hygienists (RDHs), nursing students and registered nurses (RNs) completed surveys to assess practice behaviors, knowledge, opinions, and curriculum/training about E-cigarettes. Data was analyzed with Cochran-Mantel-Haenszel tests. Results: Students (n= 146) and 144 practitioners completed surveys. Only 55.0% of DH and 18.5% nursing students reported E-cigarettes were included in their curriculum. DH students were more likely than nursing students to always ask about cigarette and e-cigarette use in health histories, to advise patients to quit e-cigarettes, and to know that e-cigarettes deliver less nicotine per puff and hold similar health risks to smokeless tobacco.  RNs were more likely to refer patients for quitting assistance than RDHs. Conclusion: DH and nursing curricula and continuing education programs must address e-cigarettes, their health effects, and how to deliver tobacco/alternative tobacco product cessation counseling.

description: This paper presents a survey of X-ray selected active galactic nuclei (AGN) with optical spectroscopic follow-up in a $\sim 18\, \rm{deg^2}$ area of the equatorial XMM-XXL north field. A sample of 8445 point-like X-ray sources detected by XMM-Newton above a limiting flux of $F_{\rm 0.5-10\, keV} > 10^{-15} \rm\,erg\, cm^{-2}\, s^{-1}$ was matched to optical (SDSS) and infrared (WISE) counterparts. We followed up 3042 sources brighter than $r=22.5$ mag with the SDSS BOSS spectrograph. The spectra yielded a reliable redshift measurement for 2578 AGN in the redshift range $z=0.02-5.0$, with $0.5-2\rm\, keV$ luminosities ranging from $10^{39}-10^{46}\rm\,erg\,s^{-1}$. This is currently the largest published spectroscopic sample of X-ray selected AGN in a contiguous area. The BOSS spectra of AGN candidates show a bimodal distribution of optical line widths allowing a separation between broad- and narrow-emission line AGN. The former dominate our sample (70 per cent) due to the relatively bright X-ray flux limit and the optical BOSS magnitude limit. We classify the narrow emission line objects (22 per cent of full sample) using standard BPT diagnostics: the majority have line ratios indicating the dominant source of ionization is the AGN. A small number (8 per cent of full sample) exhibit the typical narrow line ratios of star-forming galaxies, or only have absorption lines in their spectra. We term the latter two classes "elusive'' AGN. We also compare X-ray, optical and infrared color AGN selections in this field. X-ray observations reveal, the largest number of AGN. The overlap between the selections, which is a strong function of the imaging depth in a given band, is also remarkably small. We show using spectral stacking that a large fraction of the X-ray AGN would not be selectable via optical or IR colours due to host galaxy contamination.

description: Bullying victimization increases children’s risk for mental health and psychosomatic difficulties, substance abuse, suicide, conduct problems, economic hardship, and poor quality of life. Yet pediatricians currently lack information on which kindergarten children are likely to become bullies across the elementary school grades, when bullying screening and prevention efforts may be most effective. Our objective is to identify risk factors by kindergarten predicting which students are frequently rated by their teachers as engaging in bullying during second through fifth grade. We use multivariate regression analysis of the nationally representative Early Childhood Longitudinal Study-Kindergarten Cohort: 2010-2011 (ECLS-K: 2011). This is a population-based sample of children attending 1,310 elementary schools and surveys of their parents and teachers. Our main outcomes will be the frequency of teacher-reported bullying across second through fifth grade, as predicted by multivariable factors measured in the fall or spring of kindergarten.

Magnetic field topology of tau Sco. The uniqueness problem of Stokes V ZDI inversions

description: The early B-type star tau Sco exhibits an unusually complex, relatively weak surface magnetic field. Its topology was previously studied with the Zeeman Doppler imaging (ZDI) modelling of high-resolution circular polarisation (Stokes V) observations. Here we assess the robustness of the Stokes V ZDI reconstruction of the magnetic field geometry of tau Sco and explore the consequences of using different parameterisations of the surface magnetic maps. We succeeded in reproducing previously published magnetic field maps of tau Sco using both general harmonic expansion and a direct, pixel-based representation of the magnetic field. These maps suggest that the field topology of tau Sco is comprised of comparable contributions of the poloidal and toroidal magnetic components. At the same time, we also found that available Stokes V observations can be successfully fitted employing restricted harmonic expansions, by either neglecting the toroidal field altogether or linking the radial and horizontal components of the poloidal field as required by the widely used potential field extrapolation technique. These alternative modelling approaches lead to a stronger and topologically more complex surface field structure. The field distributions recovered with different ZDI options differ significantly, yielding indistinguishable Stokes V profiles but different linear polarisation (Stokes Q and U) signatures. Our investigation underscores the well-known problem of non-uniqueness of the Stokes V ZDI inversions. For the magnetic stars with properties similar to tau Sco (relatively complex field, slow rotation) the outcome of magnetic reconstruction depends sensitively on the adopted field parameterisation. Stokes Q and U spectropolarimetric observations represent the only way of breaking the degeneracy of surface magnetic field models.

Opiate experiences and modernity in José Asunción Silva’s De sobremesa and José María Vargas Vila’s Lirio negro
Creators: name: Hollingsworth, Philip Clark
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: During the nineteenth century and the first decades of the twentieth, opium use became increasingly common in Europe, the United States and other parts of the world. Two influential European authors, Thomas De Quincey and Charles Baudelaire, wrote about their own opiate experiences and how it impacted their creative production. Colombian authors José Asunción Silva and José María Vargas Vila employ the opiate experience in their novels De sobremesa and Lirio negro, respectively. Whilst being a means of pain relief and escape for the protagonists José Fernández and Flavio Durán, the use of opium becomes integrated in the discourse of illness. Like illness, a subject under the influence of opium is in an ambiguous state between life and death: a personal purgatory. The present work will study the opiate experiences in De sobremesa and Lirio negro as both remedy for and symptom of anxiety caused by modernity of Latin America during the turn of the twentieth century.
BLM and BSE Study 2

Subjects: subject: Social and Behavioral Sciences

description: The Black Sheep Effect (BSE) broadly refers to the tendency for individuals to derogate (i.e., negatively evaluate) ingroup deviants more than outgroup deviants. One primary explanation for this phenomenon is that ingroup derogation signals an attempt to bolster the distinctiveness and positivity associated with the social group—in other words, punishing and ingroup deviant signals, "Our group does not approve of that behavior!" In the current study, we apply this framework to a timely issue in American social life: support for the "Black Lives Matter" (BLM) movement for racial equality. We are broadly interested in how White Liberal Americans react — behaviorally and attitudinally — towards fellow Americans (henceforth "targets") who voice their support for BLM protests. We are specifically interested in how the following factors may moderate these reactions: The normativity of target's support: in other words, how tolerant for violent or aggressive protests the target is. Generally, nonviolent protest is seen as normative and acceptable, whereas violent/aggressive protests are seen as deviant. The political group membership of the target: in other words, whether or not the target is also a liberal (ingroup member) or conservative (outgroup member) The purpose of the study is to gain a deeper understanding of the social processes within groups and under what circumstances groups exhibit the Black Sheep Effect. Additionally, we aim to understand the specific feelings that ingroup members may feel towards deviant ingroup members that contribute to the Black Sheep Effect (ex: disappointment, perceptions of personality and character, etc.). This study is Study 2 in a series of studies for a Senior Honors Thesis conducted by IS.
