A remark on strict independence relations
Creators: name: Conant, Gabriel
Publisher: name: arXiv
Year: 2015
Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: We prove that if $T$ is a complete theory with weak elimination of imaginaries, then there is an explicit bijection between strict independence relations for $T$ and strict independence relations for $T^{\text{eq}}$. We use this observation to show that if $T$ is the theory of the Fraïssé limit of finite metric spaces with integer distances, then $T^{\text{eq}}$ has more than one strict independence relation. This answers a question of Adler [1, Question 1.7].

description: The proposed issue of AIS will address how some architects are embracing forms of SF to represent the intersections of these technological developments and forms of otherness and most importantly articulate those ideas through the creation of progressive architectural design position and the representation of architectural ideas. One of the objectives for a progressive speculative architecture would be to provide the visual and spatial forms that animate these narratives, giving them an immediacy and tangible presence that text alone is unable to communicate. We are living in age of great social and technological transformation: our spaces, societies, interactions and even our bodies are being transformed and the spatial consequences of our networked societies need to be fully explored as integral part of newly framed utopian architecture of the future.

North Carolina's Aero/Space Economy: Current Performance and Future Potential...Revisited
Creators: name: Harris, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: A 2006 white paper authored by the North Carolina Space Initiative suggested that North Carolina had only a "modest" presence in the traditional aerospace industry, i.e. aircraft production, airport operations, etc. However, this present study finds that traditional aerospace is an emerging part of North Carolina's economy with tremendous potential for the state's economic future. Specifically, this analysis suggests that traditional aerospace is a promising industry for North Carolina because of five primary factors. First and foremost, we find that traditional aerospace firms in North Carolina consistently pay wages well-above the overall state average and in some cases even higher than the national industry average. Second, this study contends that the state has a favorable mix of traditional aerospace industry segments. North Carolina does not have a commanding presence in every facet of the traditional aerospace industry, but the areas the state is strongest in--engine and engine parts manufacturing, replacement parts manufacturing, and maintenance and repair--are growing. Furthermore, North Carolina has become a major player in the emerging very light jet market with the recent addition of HondaJet. Third, we find that the state already has a solid foundation of aerospace-related institutions to build future efforts around including active educational partners such as North Carolina State University and other aerospace-dedicated groups like the North Carolina Aerospace Alliance. Fourth, this study suggests that the traditional aerospace industry provides economic benefit throughout the state. More importantly, we find that the state's industry is especially concentrated in the Triad region, as well as, eastern North Carolina--arguably the two areas of the state in the most need of a new economic direction. Finally, this study feels that traditional aerospace is a good fit for North Carolina because of the state's rich military aviation presence. North Carolina is home to four important military aviation facilities that spawn private sector business such as replacement part production, provide thousands of aerospace-related employment opportunities, and produce traditional aerospace workforce for private firms via retiring personnel. Nonetheless, this study finds that the industry's potential in North Carolina could be threatened by key workforce shortages, especially the state's current lack of skilled machinists. In addition to traditional aerospace, this study also investigated the potential of the budding commercial space industry to become a part of North Carolina's economic future. And while such a possibility was not ruled out completely, we find that aggressively pursuing commercial space in a meaningful fashion would be a very expensive and risky venture for the state.

Move on with Expectations and Challenges: Report for A Transportation Needs Assessment of Latino Immigrants in Lee County, North Carolina
Creators: name: Xin, Yun
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Latino immigrants in Lee County need reliable, affordable and convenient transportation options to make mandatory and maintenance trips. Public transportation could enable people to have better management of their own time, to feel independent and to travel with less stress, but the current mismatch in operating hour and service mode diminishes the usefulness of the local transit system to Latino immigrants. The local government is facing challenges in meeting the various transportation needs to sustain a life in a rural county with limited funding. The study suggests that the local transit system use the available resources more efficiently to match the unmet needs with the current service capacity of the transit system.

Molecules and dust in Cassiopeia A: II - Dust sputtering and diagnosis of dust survival in supernova remnants
Creators: name: Biscaro, Chiara

Publisher: name: arXiv
Year: 2015
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We study the dust evolution in the supernova remnant Cassiopeia A. We follow the processing of dust grains that formed in the Type II-b supernova by modelling the sputtering of grains. The dust is located in dense ejecta clumps crossed by the reverse shock. Further sputtering in the inter-clump medium once the clumps are disrupted by the reverse shock is investigated. The dust evolution in the dense ejecta clumps of Type II-P supernovae and their remnants is also studied. We study oxygen-rich clumps that describe the ejecta oxygen core, and carbon-rich clumps that correspond to the outermost carbon-rich ejecta zone. We consider the dust components formed in the supernova, several reverse shock velocities and inter-clump gas temperatures, and derive dust grain size distributions and masses as a function of time. We find that non-thermal sputtering in clumps is important and accounts for reducing the grain population by ~ 40% to 80% in mass, depending on the clump gas over-density and the grain type and size. A Type II-b supernova forms small grains that are sputtered within clumps and in the inter-clump medium. For Cas A, silicate grains do not survive thermal sputtering in the inter-clump medium. Our derived masses of currently processed silicate, alumina and carbon grains in Cas A agree well with values derived from observations. Grains produced by Type II-P supernovae better survive the remnant phase. For dense ejecta clumps, dust survival efficiencies range between 42% and 98% in mass. For the SN1987A model, the derived surviving dust mass is in the range ~ 0.06-0.13 Msolar. This type of dense supernovae may efficiently provide galaxies with dust. Specifically, silicate grains over 0.1 micron and other grains over 0,05 micron survive thermal sputtering in the remnant. Therefore, pre-solar grains of supernova origin possibly form in the dense ejecta clumps of Type II-P supernovae.

Influence of High-Speed Rail on Manufacturing Entry
Creators: name: Wang, Sen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This research investigated the association between new firm numbers and high speed rail stations. Integrated with firm-level data, city-level data, and GIS data, this research identified and examined the association at prefecture-level cities in China. The descriptive analysis profiled an imbalanced distribution of new firms’ location. The number of new firms at the east coast and central areas are much higher than southwest and northwest regions. Only a few of cities denoted a relatively large quantity of new firms. Statistical methods of both Ordinary Least Square (OLS) linear regression model and Coarsened Exact Matching (CEM) are taken for the causal inference implication. To improve the explanatory power of the selected independent variables, multiple regression models were tested. The regression model indicated that proximity to HSR stations brings a positive effect on firms’ decision making, whereas an increasing number of HSR stations at matched cities exerts a diminutive negative effect on new entrants.
Chemical potential and compressibility of quantum Hall bilayer excitons

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: This paper considers a system of two parallel quantum Hall layers with total filling factor $0$ or $1$. When the distance between the layers is small enough, electrons and holes in opposite layers form inter-layer excitons, which have a finite effective mass and interact via a dipole-dipole potential. Results are presented for the chemical potential $μ$ of the resulting bosonic system as a function of the exciton concentration $n$ and the interlayer separation $d$. Both $μ$ and the interlayer capacitance have an unusual nonmonotonic dependence on $d$, owing to the interplay between an increasing dipole moment and an increasing effective mass with increasing $d$. A phase transition between superfluid and Wigner crystal phases is shown to occur at $d \propto n^{-1/10}$. Results are derived first via simple intuitive arguments, and then verified with more careful analytic derivations and numeric calculations.

description: We study the sensitivity of current and future long-baseline neutrino oscillation experiments to the effects of dimension six operators affecting neutrino propagation through Earth, commonly referred to as Non-Standard Interactions (NSI). All relevant parameters entering the oscillation probabilities (standard and non-standard) are considered at once, in order to take into account possible cancellations and degeneracies between them. We find that the Deep Underground Neutrino Experiment will significantly improve over current constraints for most NSI parameters. Most notably, it will be able to rule out the so-called LMA-dark solution, still compatible with current oscillation data, and will be sensitive to off-diagonal NSI parameters at the level of $\varepsilon \sim \mathcal{O}(0.05 - 0.5)$. We also identify two degeneracies among standard and non-standard parameters, which could be partially resolved by combining T2HK and DUNE data.

Micro Credit And Women's Well Being: Grameen Bank As Compared To Work Force Opportunities in Bangladesh
Creators: name: Rudd, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004
Subjects: Grameen Bank

description: The purpose of this paper is to explore the ability of a micro credit institution, the Grameen Bank, to use loans to improve the well being of poor women in Bangladesh. Drawing on articles and case studies of Grameen as well as the typically available employment opportunities for women in Bangladesh I will compare micro credit and labor force employment in terms of their ability to improve women's lives. Program success can take many forms including increased income, increased ability to educate children, improved nutrition, increased ability to influence household decisions, etc. For this analysis I have chosen to focus on the following measures: Where are women making their loan investments and in what jobs are they working? How able are women to control the use of their loan money or their work force decisions? How able are women to challenge existing household relations and influence household behavior, specifically in the case of domestic violence? I have chosen the above criteria from secondary data that were readily available on women in Bangladesh with the goal of balancing the criteria among different areas to provide a more complete picture of women's income generation in Bangladesh. The goal of this analysis is to determine how different income generation opportunities for women compare and what this means for policy makers trying to improve the lives of women in Bangladesh. This paper is divided into six main sections, which are then subdivided. The first section is the Introduction. The second, Background, provides information on: the advantages of targeting anti poverty programs towards women, reasons for focusing on economic or income generation projects, and reasons for focusing on micro credit generally and Grameen Bank specifically as a strategy for income generation. This section will also explain the specifics of Grameen Bank and provide information on the status of women in Bangladesh. The third section, Hypothesis, explains my thoughts on Grameen Bank and its ability to improve the lives of women prior to conducting this research. The fourth section, Data and Analysis, will present and discuss secondary data regarding the two types of income generation being compared, micro credit, and work force participation. The fifth section will draw conclusions from these data. Finally, I have developed a list of policy recommendations based on my research for this project. Some apply specifically to Grameen, while others are more general recommendations for micro credit programs at large. Because they do not all pertain directly to the analysis in this paper, I am including them as an appendix rather than as part of the text.

The Current Factors that Affect Risk Distribution and Structure Around Emerging Ecosystem Markets in China
Creators: name: Hedglin, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: China is undergoing urbanization at a scale and speed that is
unprecedented in human history. Though urbanization has driven Chinese economic
growth, it has also caused significant environmental damage. Balancing urban
development with environmental protection is one of China’s top challenges over the
upcoming decades; as such, Chinese officials have indicated strong interest in utilizing
innovative, market-based environmental planning policies such as ecosystem service
markets. One such ecosystem service market is mitigation banking, where developers
can offset wetland destruction by purchasing “credits” for wetlands that have been
restored by mitigation banks in another area. This paper analyzes the feasibility and risk
considerations for mitigation banking in mainland China, focusing on regulatory and
entrepreneurial risk. My results suggest that the legal and administrative framework for
mitigation banking already exists within mainland China; however, regulatory and
entrepreneurial risk in the Chinese governmental context are considerably higher than
in the United States. For regulators, this is due to several factors: lack of vertical
supervision within the Chinese government, the close relationship between real estate
and politics, and the general emphasis of GDP growth over environmental protection.
For entrepreneurs, increased risk is due to uncertainty around regulations, a weak
judicial system, and general corruption. I discuss the implications of these increased
risks and suggest solutions.

Metaphysics of the Principle of Least Action

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)

description: Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics of modality and Leibniz's concept of essences or possibles striving for existence. I elaborate a modal interpretation of the principle of least action that replaces a classical representation of a system's motion along a single history in the actual modality by simultaneous motions along an infinite set of all possible histories in the possible modality. This model is based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. I interpret the action as a physical measure of the essence of every possible history. Therefore only one actual history has the highest degree of the essence and minimal action. To address the issue of necessity, I assume that the principle of least action has a general physical necessity and lies between the laws of motion with a limited physical necessity and certain laws with a metaphysical necessity.

Innovations In The Use of Low-Income Housing Tax Credits To Create Housing Affordable To People With Extremely Low Incomes
Creators: name: Peele, Tara
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: The primary purpose of this project is to examine the most current Qualified Allocation Plans (QAPs) across the United States in order to identify innovations in the use of Low-Income Housing Tax Credits (LIHTCs) to create housing for people with extremely low incomes (less than 30 percent of Area Median Income), with particular emphasis on housing for people with disabilities. The secondary purpose of this project is to recommend policies that could support the continued inclusion of targeting requirements in North Carolina Housing Finance Agency's Qualified Allocation Plans. North Carolina Department of Health and Human Services (NC DHHS) and NC Housing Finance Agency (NCHFA) have partnered to require the inclusion of targeted housing for people with disabilities in all new LIHTC developments, and in 2004, they pledged to provide rental assistance for the targeted units that were awarded tax credits in that funding cycle. In order to learn about innovative ways to target units for so-called special populations and for people with extremely low incomes, as well as to find ways to fund rental assistance, NC DHHS contracted with Tara Peele to conduct research of all other states' QAPs and identify relevant policies. Aside from the analysis of current innovative efforts to provide housing for people with extremely low incomes, this project provides a stand-alone document that profiles each state's QAP policies on deep income and special populations targeting, as well as incentives used to increase housing accessibility for people with mobility impairments and strategies to fund rental assistance. Both documents are useful to NC DHHS' efforts to work through NCHFA's tax credit allocation process to increase the supply of affordable housing for people with disabilities and people who are homeless; NC DHHS can use the information on innovations across the country to suggest policies that will address tax credit housing developers' concerns about the required targeting of units in tax credit housing. Specifically, information on what other states are doing to provide developer incentives and fund rental assistance is useful, as well as information on population-neutral targeting (i.e., using wider targeting language 'people with disabilities' rather than the more narrow and specific targeting of people with developmental or physical disabilities).

description: A two-dimensional system of photoelastic disks subject to vertical tapping against gravity was experimentally monitored from ordered to disordered configurations by varying bidispersity. The packing fraction $ϕ$, coordination number $Z$, and an appropriately defined force chain orientational order parameter $S$, all exhibit similar sharp transition with small increase in disorder. A measurable change in $S$, but not $ϕ~\&~Z$, was detected under tapping. We find disorder-induced metastability does not show configurational relaxation, but can be detected via force chain reorientations.

description: A metasurface lens (meta-lens) bends light using nanostructures on a flat surface. Macroscopic meta-lenses (mm- to cm-scale diameter) have been quite difficult to simulate and optimize, due to the large area, the lack of periodicity, and the billions of adjustable parameters. We describe a method for designing a large-area meta-lens that allows not only prediction of the efficiency and far-field, but also optimization of the shape and position of each individual nanostructure, with a computational cost that is almost independent of the lens size. As examples, we design three large NA=0.94 meta-lenses: One with 79% predicted efficiency for yellow light, one with dichroic properties, and one broadband lens. All have a minimum feature size of 100nm.

Who pays for the "good roads" state? The impacts of existing and new transportation revenue mechanisms on North Carolina drivers
Creators: name: Johnson, Harry Carl, IV
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Current transportation funding mechanisms (most notably the gas tax) are inadequate to fund the United States' transportation infrastructure needs through the Highway Trust Fund (HTF) due to a combination of inflation and increased fuel efficiency. As a result, many policymakers and transportation policy experts have recommended a transition from the current gas tax system to a fee on vehicle miles traveled (VMT). Previous studies of a VMT tax, including those conducted by several congressionally-chartered commissions, indicate that this transition will result in a more stable funding source for transportation infrastructure that acts as a true user fee on all vehicles, including those powered by alternative fuels. However, concerns have arisen regarding the distributional impacts of a VMT tax, particularly the concern that it will exert a disproportionately negative impact on low-income drivers and rural drivers. Data from the 2009 National Household Travel Survey was examined to determine the impact of a potential transition on rural and low-income drivers in North Carolina. Analysis of the data from the 2009 NHTS suggests that, for North Carolina drivers, a revenue-neutral VMT fee would not be significantly more regressive than the current gas tax. Rather, the average gas tax paid by North Carolina drivers per vehicle decreases under a revenue neutral VMT fee. Assuming that VMT will continue to decrease as individuals drive less due to rising gas prices, the average tax paid under a VMT fee will continue to decrease even further relative to the current gas tax. While rural and urban low-income drivers pay less in taxes than non-low income drivers, these individuals and households pay a higher percentage of their incomes in fuel taxes. This would not significantly change under a VMT fee, as the total tax paid would only decrease by less than a dollar for most groups. Policymakers should press for a transition to a VMT fee due to its relative stability compared to the gas tax as well as its adherence to the "user pays" principle. This study does not, however, examine the impacts of higher revenue levels (increasing the gas tax or the VMT fee). The burdens of either a higher gas tax or increased VMT fee rates can be alleviated by adjusting the Earned Income Tax Credit to account for VMT as well as supporting funding for public transportation in both urban and rural areas.

Single spin asymmetries from a single Wilson loop

description: We study the leading-power gluon transverse momentum dependent distributions (TMDs) of relevance to the study of asymmetries in the scattering off transversely polarized hadrons. Next-to-leading-order perturbative calculations of these TMDs show that at large transverse momentum they have common dynamical origins, but that in the limit of small longitudinal momentum fraction $x$ only one origin remains. We find that in this limit only the dipole-type gluon TMDs survive and become identical to each other. At small $x$ they are all given by the expectation value of a single Wilson loop inside the transversely polarized hadron, the so-called spin-dependent odderon. This universal origin of transverse spin asymmetries at small $x$ is of importance to current and future experimental studies, paving the way to a better understanding of the role of gluons in the three-dimensional structure of spin-polarized protons.

Stitching Food Into The Urban Fabric
Creators: name: Kumalah, Jasmine

description: Food systems discourse has traditionally been absent from city planning. However, the growing links between the city and the food system make it impossible for the planning field to continue to omit food systems in their practice and study. Food systems have proving to affect the health, sustainability and economic development potential of a city. The following study examines the planning and policy framework of communities with existing and proposed localized food system clusters. Localized food system clusters are an even more nascent concept. These clusters seek to leverage the concept of industry clusters with food system core components. The following study uses an evaluation of city plans, ordinances and municipal websites in order to establish the policy and planning framework of communities that foster and sustain localized food system clusters. Considerable variations exist in the way in which municipalities address food systems in their planning documents. Though vastly different in their content, all six of the evaluated communities had at least one institutional plan that addressed food system objectives. Policy wise, five of the six communities evaluated had a form of city affiliated or city supported food policy group or food systems planning group. Based on my findings, a set of recommendations was compiled for the proposed localized food system cluster in Raleigh, NC. The study ultimately establishes that local government and planners are integral to the formation and existence of localized food system clusters.
Entrepreneurship Among Low Income Homeowners

description: I examine how household demographic and financial characteristics relate to the probability of being an entrepreneur for low to moderate income homeowners in the United States. Because houses are a major source of both wealth and debt for many families in the US, mortgage underwriting may influence the entrepreneurial decision. Previous explorations of this topic provide mixed results: homeownership may provide a source of collateral with which to finance a business loan; alternatively, homeownership and entrepreneurship may both require substantial leverage and liquidity by the household and thus could be conflicting goals for households. Using household level data from the Community Advantage Panel Study (CAPS), I use regression models to estimate the probability that homeowners are entrepreneurs, operationalized as self-employment, based on their demographic, financial, and mortgage underwriting characteristics at mortgage origination. Findings confirm socio-economic disparities found in the existing literature; minority homeowners, particularly African Americans, are significantly less likely to be entrepreneurs than white ones, and females less likely than males. These results persist even when controlling for income, age, education, marital status, geographic region, credit score, and home value. In addition, the results indicate that both the loan-to-value ratio of a household’s mortgage and the receipt of a windfall payment are negatively associated with the likelihood of becoming an entrepreneur. Overall, these results suggest that highly leveraged households may be less likely to engage in entrepreneurship. Future research should consider how these relationships may change over the course of the loan term as well as how the entrepreneurial activities of low income homeowners compare to those of similar renters.

GIS-Based Real Estate Market Analysis
Creators: name: Lauff, Karl
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: This paper presents a Geographic Information System (GIS) based Real Estate Market Analysis. It uses an Aggregated Floating Trade Area (AFTA) method to compile data relative to a particular subject property. This method is an expansion upon the GIS based Floating Catchment Area method which has been successfully applied to situations outside of the real estate field. Data for the AFTA method is compiled from various sources and aggregation levels, including such data as census tracts, local tax parcel information, road networks, and zip code business patterns. This data is then aggregated to a spatially defined trade area by a spatially based weighted average, in order to provide more effective data and results for the market analysis. This paper provides a basis from which individual users can apply GIS to their particular real estate market analysis needs.
The anomalous current multiplet in 6D minimal supersymmetry

description: For supersymmetric gauge theories with eight supercharges in four, five and six dimensions, a conserved current belongs to the linear multiplet. In the case of six-dimensional $\cal N=(1,0)$ Poincaré supersymmetry, we present a consistent deformation of the linear multiplet which describes chiral anomalies. This is achieved by developing a superform formulation for the deformed linear multiplet. In the abelian case, we compute a nonlocal effective action generating the gauge anomaly.
