description: We explore the physics and observational consequences of tidal compression events (TCEs) of dark-matter clumps (DMCs) by supermassive black holes (SMBHs). Our analytic calculations show that a DMC approaching a SMBH much closer than the tidal radius undergoes significant compression along the axis perpendicular to the orbital plane, shortly after pericenter passage. For DMCs composed of self-annihilating dark-matter particles, we find that the boosted DMC density and velocity dispersion lead to a flaring of the annihilation rate, most pronounced for a velocity- dependent annihilation cross section. If the end products of the annihilation are photons, this results in a gamma-ray flare, detectable (and possibly already detected) by the Fermi telescope for a range of model parameters. If the end products of dark-matter annihilation are relativistic electrons and positrons and the local magnetic field is large enough, TCEs of DMCs can lead to flares of synchrotron radiation. Finally, TCEs of DMCs lead to a burst of gravitational waves, in addition to the ones radiated by the orbital motion alone, and with a different frequency spectrum. These transient phenomena provide interesting new avenues to explore the properties of dark matter.

Fair Housing Policy Effects on Housing Choice Voucher Holder's Spatial Integration
Creators: name: Baumann-Mitchell, Katharine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Government policies and individual prejudices have created and perpetuated patterns of residential segregation in the United States. Continued inefficient policies and individual discrimination prevent programs intended to increase opportunities for integration, such as the Housing Choice Voucher (HCV) program, from reaching their goals. Landlord discrimination may prevent many HCV households from fully utilizing their vouchers to rent a unit in neighborhoods with lower poverty and higher opportunities. Such discrimination may be thwarted by local jurisdictions including source of income as a protected class in local fair housing laws. These laws increase the likelihood that HCV households have the opportunity to rent in any neighborhood they can afford. This paper reports on a study of the impacts of source of income protections on HCV household residential concentration. This study compares spatial dispersion of HCV households in four cities, two with source of income protections and two without. The findings show that the source of income laws did not appear to decrease concentration of HCV households.

description: The objective of this study is to examine the research done surrounding the use of Patient Reported Experience Measures (PREMs) in pediatric healthcare in order to identify current gaps in the literature surrounding this topic. PREMs are validated tools used to report patient satisfaction with a health service, such as a hospitalization or health intervention [1]. These tools are generally not disease-specific, but rather are focused on the overall experience during their interaction with the health service on apsects related to accessibility and quality of care, wait times, communication, and many more [1]. One example of a PREM is the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), a validated questionnaire that measures multiple indicators of care [2]. Despite the increase in PREM usage in healthcare, there are few studies that examine the implementation of PREMs in pediatric care. Using PREMs in a pediatric population requires several considerations. For one, survey data may be collected from parents or from the children themselves [2]. Additionally, the development of any instrument must consider the age and developmental capabilities of the children using them [2]. One example of a pediatric PREM is the Child HCAHPS, similar to the adult version but developed with these considerations in mind [2]. This systematic review seeks to explore the literature and summarize available research surrounding PREM usage in pediatric healthcare.

Observational effects of a running Planck mass

description: We consider observational effects of a running effective Planck mass in the scalar-tensor gravity theory. At the background level, an increasing effective Planck mass allows a larger Hubble constant $H_0$, which is more compatible with the local direct measurements. At the perturbative level, for cosmic microwave background (CMB) anisotropies, an increasing effective Planck mass ($i$) suppresses the unlensed CMB power at $\ell \lesssim 30$ via the integrated Sachs-Wolfe effect and ($ii$) enhances CMB lensing power. Both effects slightly relax the tension between the current CMB data from the Planck satellite and the standard $Λ$CDM model predictions. However, those impacts on the CMB secondary anisotropies are subdominant, and the overall constraints are driven by the background measurements. Combining CMB data from the Planck satellite and an $H_0$ prior from Riess $et$ $al$, we find a $\sim 2σ$ hint of a positive running of effective Planck mass. However, the hint goes away when we add other low-redshift observational data including type Ia supernovae, baryon acoustic oscillations and an Universe age estimation using the oldest stars.

description: We propose several variants of the primal-dual method due to Chambolle and Pock. Without requiring full strong convexity of the objective functions, our methods are accelerated on subspaces with strong convexity. This yields mixed rates, $O(1/N^2)$ with respect to initialisation and $O(1/N)$ with respect to the dual sequence, and the residual part of the primal sequence. We demonstrate the efficacy of the proposed methods on image processing problems lacking strong convexity, such as total generalised variation denoising and total variation deblurring.

Planning for Racially Equitable (Re)Development: Leveraging the Power of Neighborhood Social & Commercial Centers in Urban Communities of Color
Creators: name: Wittekind, Cara
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: This project explores the potential for planners to leverage neighborhood social and commercial centers to create racially equitable economic change. It first calls on planning literature to establish racial economic inequity as a planning issue, both because of the inherently spatial and racial dimensions of urban poverty and because of clear linkages between planning history and racially disparate outcomes. Recognizing that person-centered policies have not been effective in addressing poverty in urban communities of color and that market-driven reinvestment in urban centers tends to result in gentrification and push-out rather than inclusive benefit, this project seeks alternative solutions. This is accomplished through a best practices analysis of equitable development concepts and the application of a package of planning analyses toward maximizing the impact of selected development tools.
Key contributions of this project include a conceptual model of economic well-being, a logic model that captures the nested nature of equitable development tools, the concept and model of a triple-lens mechanism for impactful resource targeting, a GIS tool to predict reinvestment opportunity in neighborhood centers, and assembly of a battery of spatial and quantitative analyses used to define the targeting lenses.

description: We examine subhaloes and galaxies residing in a simulated LCDM galaxy cluster ($M^{\rm crit}_{200}=1.1\times10^{15}M_\odot/h$) produced by hydrodynamical codes ranging from classic Smooth Particle Hydrodynamics (SPH), newer SPH codes, adaptive and moving mesh codes. These codes use subgrid models to capture galaxy formation physics. We compare how well these codes reproduce the same subhaloes/galaxies in gravity only, non-radiative hydrodynamics and full feedback physics runs by looking at the overall subhalo/galaxy distribution and on an individual objects basis. We find the subhalo population is reproduced to within $\lesssim10\%$ for both dark matter only and non-radiative runs, with individual objects showing code-to-code scatter of $\lesssim0.1$ dex, although the gas in non-radiative simulations shows significant scatter. Including feedback physics significantly increases the diversity. Subhalo mass and $V_{max}$ distributions vary by $\approx20\%$. The galaxy populations also show striking code-to-code variations. Although the Tully-Fisher relation is similar in almost all codes, the number of galaxies with $10^{9}M_\odot/h\lesssim M_*\lesssim 10^{12}M_\odot/h$ can differ by a factor of 4. Individual galaxies show code-to-code scatter of $\sim0.5$ dex in stellar mass. Moreover, strong systematic differences exist, with some codes producing galaxies $70\%$ smaller than others. The diversity partially arises from the inclusion/absence of AGN feedback. Our results combined with our companion papers demonstrate that subgrid physics is not just subject to fine-tuning, but the complexity of building galaxies in all environments remains a challenge. We argue even basic galaxy properties, such as the stellar mass to halo mass, should be treated with errors bars of $\sim0.2-0.4$ dex.

description: Intrinsic fluctuations of the proton saturation momentum generate asymmetric rapidity distributions on an event-by-event basis. We argue that the asymmetric component, $\left$, of the orthogonal polynomial decomposition of the two-particle rapidity correlation function is a sensitive probe to this distribution of fluctuations. We present a simple model connecting the experimentally measured $\left$ to the variance, $σ$, of the distribution of the logarithm of the proton saturation scale. We find that $σ\approx 0. 5-1$ describes the asymmetric component of the rapidity correlations recently measured by the ATLAS collaboration.

description: The classical ground states of the SU(4) Heisenberg model on the face centered cubic lattice constitute a highly degenerate manifold. We explicitly construct all the classical ground states of the model. To describe quantum fluctuations above these classical states, we apply linear flavor-wave theory. At zero temperature, the bosonic flavor waves select the simplest of these SU(4) symmetry breaking states, the four-sublattice ordered state defined by the cubic unit cell of the fcc lattice. Due to geometrical constraints, flavor waves interact along specific planes only, thus rendering the system effectively two dimensional and forbidding ordering at finite temperatures. We argue that longer range interactions generated by quantum fluctuations can shift the transition to finite temperatures.
Establishing a Regional Financial Center in Almaty: Is it Feasible?
Creators: name: Nesterova, Olga
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The Regional Financial Center of Almaty (RFCA) is one of the Kazakhstan government's premier projects aimed at diversifying the national economy and improving the country's position in the global market. This research examines the feasibility of the RFCA. For a financial center to succeed, a number of conditions must exist. Successful growth of a financial center requires a healthy financial sector and a favorable investment climate. Based on an analysis of the existing circumstances in Kazakhstan and the structure of its economy, I argue that the RFCA creates opportunities for the domestic economy, but its functional feasibility is currently constrained by the limited scope of a variety of financial services available in Kazakhstan, the distorted structure of the economy and the poor performance of the industrial sector. This analysis shows that the financial center is not feasible at this point in time and requires a sequence of investments in other sectors of the economy to support its operations and growth. Otherwise, there is a risk that the establishment of the RFCA may redirect a bulk of national resources away from other vital industries, where these resources are more needed, solely into the financial sector. This exclusive investment may ultimately lead to the failure of the RFCA.

The Social Safety Net as a Budgeting Mechanism?: The Relationship between the Earned Income Tax Credit and Financial Delinquency in Low-Income Households
Creators: name: Miller, Catherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: As policymakers weigh the costs and benefits of social safety net programs with each round of federal budget negotiations, studying the impacts of these programs on recipients’ well-being can help make the case for preserving and strengthening the safety net. To that end, this paper examines the Earned Income Tax Credit (EITC), the nation’s largest means-tested cash transfer program, and one that research shows is associated with higher educational attainment, increased workforce participation, and better health outcomes for recipients. Through a statistical analysis of approximately 2,600 low- and moderate-income households, this paper explores whether filing for the EITC is also associated with a lower likelihood of financial delinquency. I find that the probability of delaying a rent or mortgage payment is actually higher among households that file for the EITC; other statistically significant predictors of delinquency include the amount of liquid assets, the presence of an outstanding student loan, and marital status. Further research is needed to determine the extent to which the EITC and other safety net programs can assist lower-income households in budgeting for and managing their monthly financial obligations.

description: We study the directed Abelian sandpile model on a square lattice, with $K$ downward neighbors per site, $K > 2$. The $K=3$ case is solved exactly, which extends the earlier known solution for the $K=2$ case. For $K>2$, the avalanche clusters can have holes and side-branches and are thus qualitatively different from the $K=2$ case where avalance clusters are compact. However, we find that the critical exponents for $K>2$ are identical with those for the $K=2$ case, and the large scale structure of the avalanches for $K>2$ tends to the $K=2$ case.

description: Previous studies have shown that situational factors like emotional salience are associated with higher subjective levels of state empathy. The present eye-tracking study explored whether gaze behavior varies as a function of emotional salience between individuals with low and high self-reported trait empathy. In a between-subjects design, we presented three social scene images in the context of different emotion conditions (Scene 1: neutral versus positive; Scene 2: neutral versus negative; Scene 3: positive versus negative) and assessed the dwell times of individuals with low versus high self-reported empathy (measured with the Toronto Empathy Questionnaire; TEQ). Analyses revealed that whereas low- and high-TEQ participants differed in their gaze behavior after receiving neutral information, they did not differ after receiving positive or negative information. Our preliminary results suggest that gaze behavior may be more indicative of self-reported trait empathy in situations with low emotional salience than in situations with high emotional salience.
Housing Refuges: Residential Concentration and Adaptation of North Korean Refugees in Seoul, South Korea
Creators: name: Um, Ye-Rin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007
Subjects: Refugees--North Korea

description: Involuntary displacement of ethnic groups has been a long-lived phenomenon throughout human history. Constant political instabilities around the world beget groups of people crossing country borders to seek basic needs and protection. With ever more distinct sovereign states and tightened territorial boundaries, these footless people are becoming more visible these days in many countries, often being perceived as burdens on society. One of those fast growing refugee groups is North Koreans.1 While other Southeast and East Asian countries either take a hard line by sending them back to North Korea or simply overlook their existence, the South Korean government maintains an open policy towards them, admitting all identified North Korean refugees into the country based on their deep compatriotism with North Koreans.2 After entry, they are supported by many programs offered by the government, and it is likely that the budgets for these programs will significantly increase as the number of North Korean refugees grows rapidly. Therefore, evaluating the programs' outcomes and seeking ways to improve them become more crucial in promoting integration of North Koreans into South Korea and making sure the resources are not being wasted. This study is designed to aid the evaluation of housing policy towards North Korean refugees, specifically looking at the relationship between the degree of residential concentration of North Korean refugees and their adaptation in South Korea.3 The following sections first discuss the literature on refugee housing and methods used in the study. Next, South Korea's housing policy for North Korean refugees is described, raising the issue of spatial concentration. Then the relationship between residential concentration and the level of adaptation is examined both through qualitative and quantitative analysis. Finally, the implications of the research are discussed and an appropriate direction of the housing policy for North Korean refugees is proposed. Thus, the study intends to contribute to improving housing policies for North Korean refugees in a way that can bring positive adaptation outcomes and enhance stability of the South Korean society. Implications from the study may also shed light on refugee housing issues in other countries.

description: There are various no-go results forbidding self-interactions for a single partially massless spin-2 field. Given the photon-like structure of the linear partially massless field, it is natural to ask whether a multiplet of such fields can interact under an internal Yang-Mills like extension of the partially massless symmetry. We give two arguments that such a partially massless Yang-Mills theory does not exist. The first is that there is no Yang-Mills like non-abelian deformation of the partially massless symmetry, and the second is that cubic vertices with the appropriate structure constants do not exist.

An assessment of the green economy in the upper coastal plain region of North Carolina
Creators: name: Yingling, Ashley E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Harnessing the green economy has been coined as the solution to our "two biggest problems" with our two biggest problems being a loss of income and opportunity for our under and middle class workers and continued environmental degradation (Jones, 2008). While in the past we have grown our economy by exploiting both our natural and human resources, the green movement is an attempt to grow the economy through industries that restore and protect our natural resources. Many economic development and environmental agencies have forecasted incredible numbers of jobs to be created in the "green" sector, typically defined as the industries involved in conserving energy and creating clean energy. While there a wide range of projections, responsible development of this sector can provide both jobs and environmental benefits to the Upper Coastal Plain (UCP) Region. A change in policy framework, as well as increased public awareness, has created emerging markets in several green industries. Most significantly, the American Recovery and Reinvestment Act of 2009 has provided the single largest investment in clean energy thus far. Included in this bill are several procurement measures and tax credits that will spur demand for clean energy and energy efficient products. Perhaps more importantly, however, was the appropriation of $500 million to fund workforce training programs through the Green Jobs Act. The Green Jobs Act takes steps towards more fully developing and establishing skilled and competitive green industries. Furthermore, the Green Jobs Act attempts to connect low income persons and displaced workers with jobs in this growing sector. In the summer and fall of 2009, I gained personal experience working with the procurement side of green policies by assisting small towns apply for Energy Efficiency and Conservation Block grants. While providing this assistance to small towns in the Upper Coastal Plain Region with applying funds energy efficiency and renewable energy projects, I noticed that every town received energy efficiency audit services provided by contractors from Raleigh. These particular procurements benefitted the existing green economy in a nearby metropolitan center, rather than encouraging the development of a local green economy. While this sample of energy efficiency services does not provide a basis for drawing conclusions about the regional economy, it led me to my research question: how does the "green economy" fit in the Upper Coastal Plain regional economy?

Dreaming of atmospheres

Publisher: name: arXiv
Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Here we introduce the RobERt (Robotic Exoplanet Recognition) algorithm for the classification of exoplanetary emission spectra. Spectral retrievals of exoplanetary atmospheres frequently requires the preselection of molecular/atomic opacities to be defined by the user. In the era of open-source, automated and self-sufficient retrieval algorithms, manual input should be avoided. User dependent input could, in worst case scenarios, lead to incomplete models and biases in the retrieval. The RobERt algorithm is based on deep belief neural (DBN) networks trained to accurately recognise molecular signatures for a wide range of planets, atmospheric thermal profiles and compositions. Reconstructions of the learned features, also referred to as `dreams' of the network, indicate good convergence and an accurate representation of molecular features in the DBN. Using these deep neural networks, we work towards retrieval algorithms that themselves understand the nature of the observed spectra, are able to learn from current and past data and make sensible qualitative preselections of atmospheric opacities to be used for the quantitative stage of the retrieval process.

description: Our study intended to investigate whether perceived (self-reported) and objectively measured (using geographic information systems or GIS and standardized assessment protocols37) features of the transportation environment are related to walking, BMI, and hypertension, in sample data from the Multi-Ethnic Study of Atherosclerosis (MESA), a large multi-center, prospective-cohort study implemented by the National Heart, Lung, and Blood Institute (NHLBI) to study the progression of clinical and subclinical atherosclerosis. By assessing individual-level data for a large, multiethnic sample, we hoped to elucidate the relationship between individual-level health outcomes and the individual-level residential transportation environment for a diverse population, an area thus far understudied in the literature38 and a population that may have more limited access to opportunities for physical activity.39 We also hoped to strengthen the evidence base assessing the relative importance of perceived versus objective environmental variables.40 Our study also attempted to provide the first largescale assessment of the relationship between objective and subjective environmental characteristics and individual blood pressure in a diverse population. Based upon the previous literature, we expected that the presence of neighborhood pedestrian infrastructure, a denser, more highly connected roadway network, shorter distance to transit, and a greater distance from automobile-only (limited access roads) and highways will constitute a supportive infrastructure for both utilitarian and exercise walking. Perceptions of more traffic, more neighborhood noise, and higher (measured) crashes in the neighborhood were expected to deter walking based on both a likely more objectively pedestrian-hostile environment as well the effect of a perceived threat to safety on the decision to walk. As both obesity, here measured as body mass index (BMI), and blood pressure are modulated by exercise, we expected correlations between higher levels of walking and lower levels of both BMI and blood pressure. We thus expected lower levels of BMI and blood pressure to be associated with a more pedestrian-supportive environment as well.

description: We consider a modified gravity plus single-scalar-field model, where the scalar Lagrangian couples symmetrically both to the standard Riemannian volume-form (spacetime integration measure density) given by the square-root of the determinant of the Riemannian metric, as well as to another non-Riemannian volume-form in terms of an auxiliary maximal-rank antisymmetric tensor gauge field. As shown in a previous paper, the pertinent scalar field dynamics provides an exact unified description of both dark energy via dynamical generation of a cosmological constant, and dark matter as a "dust" fluid with geodesic flow as a result of a hidden Noether symmetry. Here we extend the discussion by considering a non-trivial modification of the purely gravitational action in the form of f(R) = R - αR^2 generalized gravity. Upon deriving the corresponding "Einstein-frame" effective action of the latter modified gravity-scalar-field theory we find explicit duality (in the sense of weak versus strong coupling) between the original model of unified dynamical dark energy and dust fluid dark matter, on one hand, and a specific quadratic purely kinetic "k-essence" gravity-matter model with special dependence of its coupling constants on only two independent parameters, on the other hand. The canonical Hamiltonian treatment and Wheeler-DeWitt quantization of the dual purely kinetic "k-essence" gravity-matter model is also briefly discussed.

Transit Oriented Development in Chapel Hill’s North-South Corridor: Potential for Development Around Bus Rapid Transit Corridor
Creators: name: Hanson, Phillip P.

description: Transit-oriented development (TOD) in Chapel Hill presents an opportunity for the Town to capitalize on the future investment in transit improvements to the North-South Corridor. Chapel Hill Transit is currently completing a study of transit improvement alternatives for the Corridor, which runs from Southern Village north to Eubanks Road, following 15-501, Columbia Street, and Martin Luther King Jr. Boulevard. As one of the most heavily traveled corridors in the Town, and one of the most quickly developing, projected demand for transit service in the corridor is likely to require significant investment in the next 15-20 years. One alternative for improvements to the corridor is to implement a bus rapid transit (BRT) system, creating dedicated transit stations for a bus route running in dedicated lanes. The locally-preferred alternative for Chapel Hill may involve some or all of the traditional characteristics of BRT. This study assumes that the creation of a BRT system is approved using currently proposed station locations.

description: Hyperentanglement, the entanglement in several degrees of freedom (DOFs) of a quantum system, has attracted much attention as it can be used to increase both the channel capacity of quantum communication and its security largely. Here, we present the first scheme to completely distinguish the hyperentangled Bell states of two-photon systems in three DOFs with the help of cross-Kerr nonlinearity without destruction, including two longitudinal momentum DOFs and the polarization DOF. We use cross-Kerr nonlinearity to construct quantum nondemolition detectors which can be used to make a parity-check measurement and analyze Bell states of two-photon systems in different DOFs. Our complete scheme for two-photon six-qubit hyperentangled Bell-state analysis may be useful for the practical applications in quantum information, especially in long-distance high-capacity quantum communication.

description: We investigate the effect of charge carrier interaction with surface optical phonons on the band properties of monolayer black phosphorus induced by polar substrates. We develop an analytical method based on the Lee-Low-Pines theory to calculate the spectrum of Fröhlich type continuum Hamiltonian in the long-wavelength limit. We examine the modification of a band gap and renormalization of effective masses due to the substrate-related polaronic effect. Our results show that an energy gap in supported monolayer black phosphorus is enlarged depending on a particular substrate and the interlayer distance, $z$. Among the substrate considered, the largest gap broadening at $ z=2.5$ Å is observed for the Al$_{2} $O$_{3} $ substrate, which is found to be $ \sim 50$ meV. Carrier-phonon coupling also renormalizes the effective masses which is more pronounced along the zigzag direction. Anisotropy of the effective masses becomes stronger by the influence of the polaronic effect corresponding to direction-dependent carrier-phonon coupling. We conclude that substrate phonons have a non-negligible effect on the static band properties of monolayer black phosphorus, which may be further exploited in its experimental and theoretical studies.

description: Given the wealth of the United States, the country fails at providing affordable, equitable care.
The high prevalence of chronic disease demonstrates the healthcare system’s focus on patient-centered,
treatment-based care and its lack of community-centered, preventive care. Fostered by
the 2010 Patient Protection and Affordable Care Act, hospitals and clinics are currently working
to achieve the Triple Aim: affordable care, quality care, and population health. To improve
population health, innovative practices and grants are being established. These new initiatives
focus on health equity, social determinants of health, preventive health, multi-sector
collaborations, and community-engagement. At the same time that these projects are emerging,
the connection between urban planning and public health is strengthening. By joining forces,
planning and public health practitioners as well as public and private organizations can change
the built environment and other social determinants to improve health behavior. This is an
exciting time to understand and develop techniques that change community conditions to
improve community health, and this paper focuses on one new model that does just that: the
Community-Centered Health Home (CCHH).
