Funding North Carolina's Water Infrastructure: A Coordinated Approach
Creators: name: Ashton, Rudolph
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This report addresses a potential need in North Carolina for more coordinated funding for drinking water, wastewater and stormwater infrastructure--henceforth termed "water infrastructure." North Carolina communities report that the process for obtaining public funds is difficult to navigate because of multiple funding programs housed under different agencies and a lack of clear information available to guide them through the funding process. This report defines the funding process as beginning with the identification of a project and concluding when a community receives funds for that project. Coordination among potential funding agencies may improve this process for communities. Coordination also provides a common-sense approach for the state to use its funds efficiently in ameliorating the increasingly large gap between water infrastructure needs and available funds. In February of 2006, the North Carolina Rural Economic Development Center released its Water 2030 report, which estimates that $16.6 billion in water infrastructure investments will be needed over the next 25 years. At the same time, federal and state public funding will likely continue to decrease since its peak in 1998, when the NC legislature issued a bond to fund water infrastructure.Public funding primarily concerns small (< 5,000 population) to mid-size communities (5-10,000 population) in North Carolina. Larger cities typically have the capacity to leverage their own funds and do not rely heavily on federal or state public funding agencies. Sixty percent of North Carolina's municipalities do not qualify for private infrastructure lending programs. They depend on public grants and loans to fund their water infrastructure. As of January 2006, the Small Community Water Infrastructure Exchange listed over thirty states that have some coordinating body to assist communities in funding water infrastructure. These state bodies range dramatically in their level of formality and breadth of services provided. No information is available on the relative success of these state models, but the EPA has published a handbook on coordinating funding at the state-level using case studies of six states.

description: We present new, tight, constraints on the cosmological background of gravitational waves (GWs) using the latest measurements of CMB temperature and polarization anisotropies provided by the Planck, BICEP2 and Keck Array experiments. These constraints are further improved when the GW contribution $N^{\rm GW}_{\rm eff}$ to the effective number of relativistic degrees of freedom $N_{\rm eff}$ is also considered. Parametrizing the tensor spectrum as a power law with tensor-to-scalar ratio $r$, tilt $n_\mathrm{t}$ and pivot $0.01\,\mathrm{Mpc}^{-1}$, and assuming a minimum value of $r=0.001$, we find $r < 0.089$, $n_\mathrm{t} = 1.7^{+2.1}_{-2.0}$ ($95\%\,\mathrm{CL}$, no $N^{\rm GW}_{\rm eff}$) and $r < 0.082$, $n_\mathrm{t} = -0.05^{+0.58}_{-0.87}$ ($95\%\,\mathrm{CL}$, with $N^{\rm GW}_{\rm eff}$). When the recently released $95\,\mathrm{GHz}$ data from Keck Array are added to the analysis, the constraints on $r$ are improved to $r < 0.067$ ($95\%\,\mathrm{CL}$, no $N^{\rm GW}_{\rm eff}$), $r < 0.061$ ($95\%\,\mathrm{CL}$, with $N^{\rm GW}_{\rm eff}$). We discuss the limits coming from direct detection experiments such as LIGO-Virgo, pulsar timing (European Pulsar Timing Array) and CMB spectral distortions (FIRAS). Finally, we show future constraints achievable from a COrE-like mission: if the tensor-to-scalar ratio is of order $10^{-2}$ and the inflationary consistency relation $n_\mathrm{t} = -r/8$ holds, COrE will be able to constrain $n_\mathrm{t}$ with an error of $0.16$ at $95\%\,\mathrm{CL}$. In the case that lensing $B$-modes can be subtracted to $10\%$ of their power, a feasible goal for COrE, these limits will be improved to $0.11$ at $95\%\,\mathrm{CL}$.

Case Study of Floodplain Acquisition/Relocation Project in Kinston, NC after Hurricane Fran (1996) and Hurricane Floyd (1999)
Creators: name: McCann, Monica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006
Subjects: Hurricane Fran, 1996
Hurricane Floyd, 1999

description: Kinston, North Carolina is a good example of how acquisition and relocation, when properly planned and combined with other smart growth strategies, can results in a better community overall. The city was struck by two devastating hurricanes in a relatively short period (Hurricane Fran in September 1996 and Hurricane Floyd in September 1999) and suffered major flooding, economic disruption, and environmental problems. In response, the city implemented a successful buyout and relocation initiative despite seemingly limited resources (the city struggles with a largely stagnant economy and a significant percentage of vulnerable populations). In addition, Kinston used the acquisition project as the implementation tool for a host of other smart growth projects including downtown revitalization efforts, promotion of affordable housing and the creation of an ambitious green infrastructure plan. The purpose of this case study was to examine the process that Kinston undertook on its road to recovery in an attempt to determine why the city was so successful. The study suggests that one of the keys to success is a quick response time. The Hazard Mitigation Grant Program (HMPG), which funds acquisitions, has a long processing time. This, coupled with the large administrative tasks the community has to accomplish before a buyout can take place (title searches, legal property surveys, appraisals, etc.), allows a significant amount of time to pass during which the resolves of residents to participate wanes. Kinston was "fortunate" to experience its second hurricane only three years after the first. It not only motivated residents to participate in the program, but a large portion of the program was simply rolled over to begin including Hurricane Floyd victims, eliminating the long time lapse between disaster and deed transaction.

description: We study cross-Kerr (CK) effect on an optomechanical system driven by two-tone fields. We show that in the presence of the CK effect, a bistable behavior of the mean photon number in the cavity becomes more robust against the fluctuations of the frequency detuning between the cavity mode and the control field. The bistability can also be turned into a tri-stability within the experimentally accessible range of the system parameters. Also, we find that the symmetric profile of the optomechanically induced transparency is broken and the zero-absorption point is shifted in the presence of the CK effect. This shift can be used to measure the strength of the CK effect, and the asymmetric absorption profiles can be employed to engineer a high quality factor of the cavity.

description: We determine closed and compact expressions for the epsilon-expansion of certain Gaussian hypergeometric functions expanded around half-integer values by explicitly solving for their recurrence relations. This epsilon-expansion is identified with the normalized solution of the underlying Fuchs system of four regular singular points. We compute its regularized zeta series (giving rise to two independent associators) whose ratio gives the epsilon-expansion at a specific value. Furthermore, we use the well known one-loop massive bubble integral as an example to demonstrate how to obtain all-order epsilon-expansions for Feynman integrals and how to construct representations for Feynman integrals in terms of generalized hypergeometric functions. We use the method of differential equations in combination with the recently established general solution for recurrence relations with non-commutative coefficients.

description: A three-terminal Josephson junction biased at opposite voltages can sustain a phase-sensitive dc-current carrying three-body static phase coherence, known as the "quartet current". We calculate the zero-frequency current noise cross-correlations and answer the question of whether this current is noisy (like a normal current in response to a voltage drop) or noiseless (like an equilibrium supercurrent in response to a phase drop). A quantum dot with a level at energy $ε_0$ is connected to three superconductors $S_a$, $S_b$ and $S_c$ with gap $Δ$, biased at $V_a=V$, $V_b=-V$ and $V_c=0$, and with intermediate contact transparencies. At zero temperature, nonlocal quartets (in the sense of four-fermion correlations) are noiseless at subgap voltage in the nonresonant dot regime $ε_0/Δ\gg 1$, which is demonstrated with a semi-analytical perturbative expansion of the cross-correlations. Noise reveals the absence of granularity of the superflow splitting from $S_c$ towards $(S_a,S_b)$ in the nonresonant dot regime, in spite of finite voltage. In the resonant dot regime $ε_0/Δ< 1$, cross-correlations measured in the $(V_a,V_b)$ plane should reveal an "anomaly" in the vicinity of the quartet line $V_a+V_b=0$, related to an additional contribution to the noise, manifesting the phase sensitivity of cross-correlations under the appearance of a three-body phase variable. Phase-dependent effective Fano factors $F_φ$ are introduced, defined as the ratio between the amplitudes of phase modulations of the noise and the currents. At low bias, the Fano factors $F_φ$ are of order unity in the resonant dot regime $ε_0/Δ< 1$, and they are vanishingly small in the nonresonant dot regime $ε_0/Δ\gg 1$.

On higher spin symmetries in de Sitter QFTs
Creators: name: Costa, Renato
name: Morrison, Ian A.
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the consequences of global higher-spin symmetries in quantum field theories on a fixed de Sitter background of spacetime dimension $D \ge 3$. These symmetries enhance the symmetry group associated with the isometries of the de Sitter background and thus strongly constrain the dynamics of the theory. In particular, we consider the case when a higher spin charge acts linearly on a scalar operator to leading order in a Fefferman-Graham expansion near the future/past conformal boundaries. We show that this implies that the expectation values of the operator inserted near the boundaries are asymptotically Gaussian. Thus, these operators have trivial cosmological spectra, and on global de Sitter these operators have only Gaussian correlations between operators inserted near future/past infinity. The latter result may be interpreted as an analogue of the Coleman-Mandula theorem for QFTs on de Sitter spacetime.

Barriers to small business development Chapel Hill, NC
Creators: name: Schroeder, Heather R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: To learn about barriers to market entry for local small businesses, the Town of Chapel Hill hired a consultant to speak with owners, managers, and other individuals knowledgeable about small business development and operation in Chapel Hill. From the 17 completed interviews, several issues emerged as barriers to entry for small business in Chapel Hill. The findings presented here will inform future policy decisions and programming opportunities by local government and non-government groups to facilitate small business development and retention in Chapel Hill. Business owners and managers, as well as developers and other individuals knowledgeable about the local business climate, were asked the following questions: What are the positive aspects of working with the Town to open/operate a business? What are the negative aspects, challenges, or barriers to opening a business in Chapel Hill? How could the Town better serve its small business owners? A. POSITIVE Chapel Hill's location--close to major transportation routes as well as the University of North Carolina--and its customer base were noted as positive aspects of doing business locally. In addition, interviewees praised efforts by the Chapel-Hill Carrboro Chamber of Commerce--including promotion of the "Buy Local" initiative--and the Chapel Hill Downtown Partnership. One business said the Town staff had been "good facilitators" for opening a business, but vast criticism of the Town's development processes overshadowed this sparse praise. B. NEGATIVE The majority of comments about barriers to small business development addressed issues in local government. Topics ranged from the Planning Department's sign ordinance and permitting process, to the high cost of property taxes and lack of step-by-step instructions for new businesses. Issues specific to downtown businesses included high rent, a lack of retail diversity and density, problems with parking availability and costs, and the presence of homeless people and panhandlers. Businesses that have operated in both Chapel Hill and other municipalities cited a few differences between local government policies, including a more straightforward process in Carrboro and Chatham County and the availability of low-interest loans, cheaper space, parking, highway access, and straightforward development review in Durham.

Do Biases Exist in the Location of Affordable Housing? An Examination of the Low-Income Housing Tax Credit in North Carolina
Creators: name: Kiddoo, David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: This paper first establishes the importance of the Low-Income Housing Tax Credit (LIHTC) as a subsidy for the production of affordable housing in the United States, and then examines LIHTC allocation patterns in North Carolina in an attempt to determine possible biases in the production process. Analysis of allocation data shows a strong correlation between the presence of commercial bank branches and LIHTC allocation patterns on a county-by-county basis, even after controlling for population. Through a detailed analysis of allocation patterns and interviews with key informants in the LIHTC industry, three possible biases are suggested. First, LIHTC developers and properties may be spatially correlated due to time and cost savings as well as a need for specialized knowledge and local relationships. Second, the financial involvement of local government may be an important factor in development decisions both as a result of state finance agency regulations and implications for financial feasibility. Finally, decisions made by LIHTC investors may be playing a role in location decisions, although the extent of this role can be debated. The production of affordable housing through the Low-Income Housing Tax Credit (LIHTC) program is neither perfectly efficient nor of sufficient scope to completely solve housing affordability problems in the United States. However, affordable housing advocates should be aware of the significant victory that the program represents for those in need of housing assistance given the climate that social programs have faced both before and since the creation of the LIHTC in 1986. The combination of an ever-worsening budgetary climate, a continued emphasis on devolution with respect to social programs formerly sponsored by the Federal government, and the shift from the provision of multifamily housing assistance to homeownership assistance by the U.S. Department of Housing and Urban Development (HUD) represent a very real threat to the survival of the LIHTC. Affordable housing advocates would be well advised to protect and maximize the efficient use of resources that are currently available from the Federal government until a political climate that allows for the expansion of social programs arises once again. This paper examines issues surrounding the operation and survival of the LIHTC in two parts. First, the political climate surrounding affordable housing policy over the past four decades is examined, with a goal of establishing the improbability of the creation of the LIHTC as well as an argument for its importance to current affordable housing provision in the United States; and second, allocation patterns of the LIHTC in North Carolina are examined, with an eye on identifying potential program weaknesses that may need to be remedied to promote program efficiency, equity, and survival.

description: We study chaos and scrambling in unitary channels by considering their entanglement properties as states. Using out-of-time-order correlation functions to diagnose chaos, we characterize the ability of a channel to process quantum information. We show that the generic decay of such correlators implies that any input subsystem must have near vanishing mutual information with almost all partitions of the output. Additionally, we propose the negativity of the tripartite information of the channel as a general diagnostic of scrambling. This measures the delocalization of information and is closely related to the decay of out-of-time-order correlators. We back up our results with numerics in two non-integrable models and analytic results in a perfect tensor network model of chaotic time evolution. These results show that the butterfly effect in quantum systems implies the information-theoretic definition of scrambling.

Inclusionary housing in North Carolina: an exploratory case study of four North Carolina communities
Creators: name: Schiepan, Joella Renee
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Housing, especially affordable housing (AH), influences health outcomes on both an individual and on a community-wide level. AH is a crucial component of healthy communities; its availability ensures the continued ability to attract and retain businesses and the means to sustain employment growth. Therefore, a lack of AH can negatively influence the local economy and health. The ability to access AH is important on an individual level because it influences health in three important ways: The quality of a house can lead to individual health outcomes (i.e., asthma and lead poisoning); the location of a house can influence life-long opportunities (i.e., access to education, quality healthcare) and have other neighborhood level health effects; and the affordability of a house can influence opportunity costs (i.e., forcing individuals to make choices between spending money on housing and other needed items) and hinder a family's ability to pay for other necessities, such as nutritious food and healthcare. The affordability of housing is a key determinant of health. One strategy that attempts to alleviate the health-related issues of limited affordable housing (quality, location and affordability) is inclusionary zoning. Inclusionary zoning, also referred to as inclusionary housing (IH), requires that developers provide a percentage of units as affordable to low- and moderate-income households in new developments. IH requires that private developers provide much needed AH which will benefit the "working poor" in growing municipalities. The policy has been successfully implemented across the United States, including communities in California, Colorado, Virginia and Montgomery County, Maryland. Despite the success of IH policies in other growing states, few North Carolina municipalities have successfully incorporated IH as an approach to address their increasing needs for AH. The project's overall goal was to understand why some municipalities in North Carolina have created an inclusionary housing (IH) policy, while others have not. In-depth interviews with public officials, affordable housing advocates, and developers in a sampling of four North Carolina municipalities using or considering an IH policy will be utilized to answer the following research questions: 1. What is the economic, social, and political context in which affordable housing is articulated as a policy problem? 2. What economic, social, and political factors are associated with using inclusionary housing as the policy solution? Results from this project will inform affordable housing advocates, community leaders and policymakers about affordable housing policy development within North Carolina municipalities, including the policy of IH.

description: We give a quantitative version of Vainberg's method relating pole free regions to propagation of singularities for black box scatterers. In particular, we show that there is a logarithmic resonance free region near the real axis of size $τ$ with polynomial bounds on the resolvent if and only if the wave propagator gains derivatives at rate $τ$. Next we show that if there exist singularities in the wave trace at times tending to infinity which smooth at rate $τ$, then there are resonances in logarithmic strips whose width is given by $τ$. As our main application of these results, we give sharp bounds on the size of resonance free regions in scattering on geometrically nontrapping manifolds with conic points. Moreover, these bounds are generically optimal on exteriors of nontrapping polygonal domains.

The Effect Of Open Space On Residential Property Values In Wake County, NC
Creators: name: Henderson, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

Subjects: Property tax

description: This Masters Project employs hedonic price analysis, a revealed preference method, to estimate a component of the economic value of open space in Wake County, NC. Specifically, I seek to quantify the portion of economic value that is reflected in increased sale prices of single-family residential properties. If significant, these results can be used to calculate the incremental property tax revenue associated with open spaces, demonstrating that open spaces actually do provide a modest return to local government in the form of increased property taxes. As mentioned above, this research could also be used to encourage additional private provision of open space, by showing a positive relationship between proximity to private open spaces and house sale price.

description: We present VIMOS-VLT spectroscopy of the Frontier Fields cluster MACS~J0416.1-2403 (z=0.397). Taken as part of the CLASH-VLT survey, the large spectroscopic campaign provided more than 4000 reliable redshifts, including ~800 cluster member galaxies. The unprecedented sample of cluster members at this redshift allows us to perform a highly detailed dynamical and structural analysis of the cluster out to ~2.2$r_{200}$ (~4Mpc). Our analysis of substructures reveals a complex system composed of a main massive cluster ($M_{200}$~0.9$\times 10^{15} M_{\odot}$) presenting two major features: i) a bimodal velocity distribution, showing two central peaks separated by $ΔV_{rf}$~1100 km s$^{-1}$ with comparable galaxy content and velocity dispersion, ii) a projected elongation of the main substructures along the NE-SW direction, with a prominent subclump ~600 kpc SW of the center and an isolated BCG approximately halfway between the center and the SW clump. We also detect a low mass structure at z~0.390, ~10' S of the cluster center, projected at ~3Mpc, with a relative line-of-sight velocity of $ΔV_{rf}$~-1700 km s$^{-1}$. The cluster mass profile that we obtain through our dynamical analysis deviates significantly from the "universal" NFW, being best fit by a Softened Isothermal Sphere model instead. The mass profile measured from the galaxy dynamics is found to be in relatively good agreement with those obtained from strong and weak lensing, as well as with that from the X-rays, despite the clearly unrelaxed nature of the cluster. Our results reveal overall a complex dynamical state of this massive cluster and support the hypothesis that the two main subclusters are being observed in a pre-collisional phase, in line with recent findings from radio and deep X-ray data. With this article we also release the entire redshift catalog of 4386 sources in the field of this cluster.

description: The notion of a Killing tensor is generalised to a superspace setting. Conserved quantities associated with these are defined for superparticles and Poisson brackets are used to define a supersymmetric version of the Schouten-Nijenhuis bracket. Superconformal Killing tensors in flat superspaces are studied for spacetime dimensions 3,4,5,6 and 10. These tensors are also presented in analytic superspaces and super-twistor spaces for 3,4 and 6 dimensions. Algebraic structures associated with superconformal Killing tensors are also briefly discussed

Wherever you go, there they are? Bicycle parking in Chapel Hill, NC
Creators: name: Ousdahl, Michael Steven
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Municipalities continue to promote the economic, environmental, and health benefits of bicycling. Consistent with this objective, municipalities have increased efforts to install and improve bicycle parking facilities. However, there is limited research examining how usage of these facilities interacts with infrastructure, land use, and the built environment. This research begins to fill this gap through an examination of the association between bicycle rack design, land use, and built environment characteristics on bicycle rack usage. A complete inventory and existing conditions report of all bicycle racks and cumulative bicycle parking spaces located within the corporate limits of the Town of Chapel Hill, NC was undertaken. A total of n=716 bicycle racks were inventoried and assessed based on usage of each facility during a work week midday period of 12:30pm-1:30pm. A zero-inflated negative binomial regression model was developed to examine associations between bicycle rack usage and bicycle rack design, land use, and built environment characteristics. Results find that type of rack, condition of the rack, accessibility, population density, employment density, street connectivity, distance to UNC, and distance to the nearest bicycle lane or path serve as significant predictors of bicycle rack usage. Looking across the results, built environment factors are found to serve as the strongest predictors of bicycle rack usage. These results add to the existing research literature by identifying determinants that significantly predict usage of bicycle parking facilities. Accordingly, these results will aid transportation decision-makers with additional insight and considerations behind the siting of new bicycle parking facilities. Future research is encouraged to further explore these associations from a qualitative standpoint such as through interviews of bicyclists utilizing various bicycle parking facilities.

description: We present MUSE observations in the core of the HFF galaxy cluster MACS J1149.5+2223, where the first magnified and spatially-resolved multiple images of SN 'Refsdal' at redshift 1.489 were detected. Thanks to a DDT program with the VLT and the extraordinary efficiency of MUSE, we measure 117 secure redshifts with just 4.8 hours of total integration time on a single target pointing. We spectroscopically confirm 68 galaxy cluster members, with redshift values ranging from 0.5272 to 0.5660, and 18 multiple images belonging to 7 background, lensed sources distributed in redshifts between 1.240 and 3.703. Starting from the combination of our catalog with those obtained from extensive spectroscopic and photometric campaigns using the HST, we select a sample of 300 (164 spectroscopic and 136 photometric) cluster members, within approximately 500 kpc from the BCG, and a set of 88 reliable multiple images associated to 10 different background source galaxies and 18 distinct knots in the spiral galaxy hosting SN 'Refsdal'. We exploit this valuable information to build 6 detailed strong lensing models, the best of which reproduces the observed positions of the multiple images with a rms offset of only 0.26". We use these models to quantify the statistical and systematic errors on the predicted values of magnification and time delay of the next emerging image of SN 'Refsdal'. We find that its peak luminosity should should occur between March and June 2016, and should be approximately 20% fainter than the dimmest (S4) of the previously detected images but above the detection limit of the planned HST/WFC3 follow-up. We present our two-dimensional reconstruction of the cluster mass density distribution and of the SN 'Refsdal' host galaxy surface brightness distribution. We outline the roadmap towards even better strong lensing models with a synergetic MUSE and HST effort.
