description: Human experiments have demonstrated that instrumental performance and causal beliefs of the effectiveness of an action in producing an outcome are correlated and driven by the probability of each action leading to a reward. The animal literature, however, shows that instrumental free-operant performance differs when outcome probabilities are matched while subjects undergo training under ratio or interval schedules of reward. In two experiments, we investigated whether humans causal beliefs would correlate with instrumental performance under interval and ratio schedules while matching outcome probabilities within subjects. We replicated the effect of reward schedule training on instrumental performance found in animals using two different types of interval schedules. However, we found that in both experiments causal beliefs were similar, and were higher when experienced outcome probabilities were increased in both schedules by experimental manipulations. These results suggest that instrumental performance and causal attribution in humans do not follow from the same psychological process under free-operant training.

description: We present H$α$ gas kinematics for 178 star-forming galaxies at z~2 from the MOSFIRE Deep Evolution Field survey. We have developed models to interpret the kinematic measurements from fixed-angle multi-object spectroscopy, using structural parameters derived from CANDELS HST/F160W imaging. For 35 galaxies we measure resolved rotation with a median $(V/σ_{V,0})_{R_E}=2.1$. We derive dynamical masses from the kinematics and sizes and compare them to baryonic masses, with gas masses estimated from dust-corrected H$α$ star formation rates (SFRs) and the Kennicutt-Schmidt relation. When assuming that galaxies with and without observed rotation have the same median $(V/σ_{V,0})_{R_E}$, we find good agreement between the dynamical and baryonic masses, with a scatter of $σ_{RMS}=0.34$dex and a median offset of $Δ\log_{10}M=0.04$dex. This comparison implies a low dark matter fraction (8% within an effective radius) for a Chabrier initial mass function (IMF), and disfavors a Salpeter IMF. Moreover, the requirement that $M_{dyn}/M_{baryon}$ should be independent of inclination yields a median value of $(V/σ_{V,0})_{R_E}=2.1$ for galaxies without observed rotation. If instead we treat the galaxies without detected rotation as early-type galaxies, the masses are also in reasonable agreement ($Δ\log_{10}M=-0.07$dex, $σ_{RMS}=0.37$dex). The inclusion of gas masses is critical in this comparison; if gas masses are excluded there is an increasing trend of $M_{dyn}/M_{*}$ with higher specific SFR (SSFR). Furthermore, we find indications that $V/σ$ decreases with increasing H$α$ SSFR for our full sample, which may reflect disk settling. We also study the Tully-Fisher relation and find that at fixed stellar mass $S_{0.5}=(0.5V_{2.2}^2+σ_{V,0}^2)^{1/2}$ was higher at earlier times. At fixed baryonic mass, we observe the opposite trend. [abridged]

An Evaluation of a Demand-Responsive Transit Pilot in North Carolina's Research Triangle Park
Creators: name: Lang, Kathryn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: GoTriangle, the regional transit agency for the Triangle region of North Carolina, is conducting an innovative, shared ride, demand-responsive transit pilot in Research Triangle Park (RTP). This demand-responsive transit pilot, called Go OnDemand, replaces four fixed-route shuttles. GoTriangle hopes that this pilot program will improve transit service in RTP, provide greater mobility and accessibility, and potentially reduce costs.This pilot is part of a larger, national transportation trend. Transit agencies are shifting operations toward mobility as a service (MaaS) and exploring non-traditional ways of providing mobility to customers, using mobile apps, partnerships with the private sector, and shared models. Go OnDemand fits with this trend, adding a high-tech component to traditional dial-a-ride service by partnering with TransLoc and targeting the service in low-density area of the Triangle where this type of transit model makes sense.Given its innovative and unique operating structure, demand-responsive transit services like Go OnDemand can be difficult to evaluate. This paper attempts to frame Go OnDemand in context by reviewing existing demand-responsive transit performance measures, examining demand-responsive transit typologies, bringing in customer-focused performance indicators, and where possible, comparing Go OnDemand performance to baseline metrics from other comparable services. This paper also looks at Go OnDemand’s initial performance over a four-week time period to identify early wins and challenges for the pilot.Initial results from the pilot suggest that the Go OnDemand is providing different but effective transit service in RTP. The expansion of midday service is clearly an added benefit, and so are the additional connections that the point-to-point service provides to apartment complexes and commercial establishments within the service area. At the same time, predictability for regional connections has been reduced, and the service has not yet provided the hoped-for vehicle miles traveled (VMT) reductions. Many of the performance indicators should be monitored throughout the six months of the pilot to identify areas for adjustment.This paper provides an initial look at how to evaluate the Go OnDemand transit service, baseline performance metrics across various indicators, and an analysis of initial data. Further evaluation activities will be necessary at the end of the pilot to assist in service planning for next year and beyond.

description: Photonic crystals (PhCs) have emerged as a popular platform for realizing various topological phases due to their flexibility and potential for device applications. In this article, we present a comprehensive classification of topological bands in one- and two dimensional photonic crystals, with and without time-reversal symmetry. Our approach exploits the symmetry representations of field eigenmodes at high-symmetry points in momentum space, allowing for the efficient design of a wide range of topological PhCs. In particular, we show that the complete classification provided here is useful for diagnosing photonic crystal analogs of obstructed atomic limits, fragile phases, and stable topological phases that include bands with Dirac points and Chern numbers.

description: The lively spread of COVID-19 has lockdown the countries across the globe. This study aims to assess the awareness, identify the best practices on protective measures against COVID-19 suggested by WHO (World Health Organization) among the academicians of India and United Arab Emirates (UAE) and also to know the preference for engaging themselves during lock-down period. A descriptive method was chosen for the research and both primary and secondary data were used in this study. Primary data were collected from the resident academics of India and United Arab Emirates. Secondary data were gathered from online resources for better understanding. An online survey (hosted by www.forms.google.com) was designed and circulated through authors’ known group emails, multiple WhatsApp groups and posted in linkedin.com so as to collect data. It has been identified that 669 (90.53%) surveyed participants hold undergraduate and above degree qualifications. It is observed that majority (89.72%) of the participants strongly agreed with social distancing which is the best practice against COVID-19. 710 (96.08%) academics positively responded to avoid touching eyes, nose and mouth. It was found that very less (5.68%) number of sample group agreed against for practicing respiratory hygiene. The present study has been conducted among the working group of educational institutions. Though there were many ways to identify them, only known individuals have been communicated to record their feedback about the impact of covid 19. An attempt has been made to explore the notions of academics about covid 19. The study is the original work and reveals the ideas and thoughts of the sample group. No such a work has been carried out in any part of the world with the academic sample population. This study will lead to encourage the individuals to take up the same approach with different sample size and geographical limitations

Collision Course Cities: Implementing Regional Governance in the Austin - San Antonio Corridor
Creators: name: Williams, Mary Beth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This report examines regional governance and planning processes in the Austin – San Antonio Corridor to understand how and why attempts at regional collaboration breakdown. An analysis of three previous attempts at regional coordination as well as interviews with local planning experts and regional leaders provide the foundation for a case study of how the communities in this corridor have wrestled with regional governance, what factors have ultimately contributed to little concrete progress, and what the prospects are for future collaboration. In order to reverse this trend and successfully entrench regional collaboration as an effective planning tool in addressing this rapidly growing corridor, the following strategies are recommended: build a parent entity to lead the movement, prioritize strategy into short-term and long-term goals, create a dual education approach targeting both the public and the legislature, and start working immediately on the path of least resistance.

We show that the thermoelectric DC conductivity of the field theory can be obtained by solving a system of generalised Stokes equations on the black hole horizon. For various examples, including Q-lattices and one-dimensional lattices, we solve the Stokes equations explicitly and obtain expressions for the DC conductivity in terms of the solution at the black hole horizon.

description: We propose a general framework for increasing local stability of Artificial Neural Nets (ANNs) using Robust Optimization (RO). We achieve this through an alternating minimization-maximization procedure, in which the loss of the network is minimized over perturbed examples that are generated at each parameter update. We show that adversarial training of ANNs is in fact robustification of the network optimization, and that our proposed framework generalizes previous approaches for increasing local stability of ANNs. Experimental results reveal that our approach increases the robustness of the network to existing adversarial examples, while making it harder to generate new ones. Furthermore, our algorithm improves the accuracy of the network also on the original test data.
Measuring the effectiveness of selectivity: an analysis of the MCC foreign aid model
Creators: name: Kajer, Jason
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: The literature has shown that one of the key challenges of evaluating development programs is disaggregating the complex role that incentives play. Departing from the previous studies related to the MCC model, which focused exclusively on the so-called MCC effect on countries before they became eligible for aid, this study aims to provide insight into the effectiveness of selectivity in influencing long-term policy reforms by looking at how countries are responding to the program after attaining eligibility or recipient status. It is worth noting that this study does not attempt to evaluate the appropriateness of the policy reforms being promoted by MCC, but only the model's effectiveness at inducing long-term adoption of these policies by eligible and recipient countries. I use a difference-in-difference time series regression model to examine the question of whether reaching the eligibility threshold or being awarded funding has an effect on how countries perform on the eligibility criteria. Specifically, I aim to answer the questions: Does country performance on policy reforms decrease after countries attain eligibility status or receive aid? And, is there a difference between how low-income countries (LICs) and lower-middle-income countries (LMICs) respond to the program overtime? Answering these questions is vital to gaining a better understanding of the incentive structure at play within an aid allocation model based on competitive selectivity.

description: Quantum key distribution provides a promising solution for sharing secure keys between two distant parties with unconditional security. Nevertheless, quantum key distribution is still severely threatened by the imperfections of devices. In particular, the classical pulse correlation threatens security when sending decoy states. To address this problem and simplify experimental requirements, we propose a phase-matching quantum key distribution protocol without intensity modulation. Instead of using decoy states, we propose a novel method to estimate the theoretical upper bound on the phase error rate contributed by even-photon-number components. Simulation results show that the transmission distance of our protocol could reach 305 km in telecommunication fiber. Furthermore, we perform a proof-of-principle experiment to demonstrate the feasibility of our protocol, and the key rate reaches 22.5 bps under a 45 dB channel loss. Addressing the security loophole of pulse intensity correlation and replacing continuous random phase with 6 or 8 slices random phase, our protocol provides a promising solution for constructing quantum networks.

Tax base diversification in Carrboro: from bedroom community to bedrock for economic stability
Creators: name: Deignan Reis, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Carrboro, North Carolina, has the fifth-highest residential property tax rate in the state, and its homes are valued higher than the municipalities with higher tax rates. Residential use comprises 86% of Carrboro's development, meaning businesses contribute little in property and sales taxes. Housing values have increased in recent decades, while diversity and affordability have dwindled. Non-residential development has been slow in Carrboro, due to a complex combination of existing policies and political will. Whether the town should change its policies and procedures to help diversify the land uses, tax revenue sources, and family backgrounds in Carrboro depends on whether Carrboro's residents actually want more non-residential development. If they do, this Master's Project uses a case study of Arcata, California to suggest specific revisions to Carrboro's development guide, zoning map and land use ordinance that could help speed the non-residential development review process and more aggressively promote affordable housing.

description: This paper considers a variation of the full-information secretary problem where the random variables to be observed are independent but not necessary identically distributed. The main result is a sharp lower bound for the optimal win probability. Precisely, if $X_1,\dots,X_n$ are independent random variables with known continuous distributions and $V_n(X_1,\dots,X_n):=\sup_τP(X_τ=M_n)$, where $M_n:=\max\{X_1,\dots,X_n\}$ and the supremum is over all stopping times adapted to $X_1,\dots,X_n$, then $$V_n(X_1,\dots,X_n)\geq \left(1-\frac{1}{n}\right)^{n-1},$$ and this bound is attained. The method of proof consists in reducing the problem to that of a sequence of two-valued random variables, and then applying Bruss' sum-the-odds theorem (2000). In order to obtain a sharp bound for each $n$, we improve Bruss' lower bound (2003) for the sum-the-odds problem.

Success in Adding Value: The Case of The Agro-Processing Sector in Ghana West Africa
Creators: name: Yow, Leigh Anne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Agricultural entrepreneurs in developing countries have begun to look toward value-added (VA) production as the next key strategy for economic growth. Increasing competition due to the globalization of production and trade has led a growing number of developing countries to encourage exports as important part of improving international competitiveness. This strategy is consistent with the current consensus in the literature. The strategy further suggests targeting nontraditional exports (NTEs) to diversify the economy. VA production is a way to increase the amount of price control over NTEs, and improve the income potential for developing countries. For this reason, this research explores why some Ghanaian agricultural firms have succeeded at VA exports and others have not. In addition, it looks at what conclusions can we draw about what firms, business associations, and the government can do in developing countries to stimulate and encourage VA production. The argument of this research paper is that in successful cases, the achievement of viable VA production was the result of a sequence of steps. These steps form the three themes that this paper will discuss within the context of Ghana. The first, leverage of resources through organizational arrangements and mergers, helps firms to capitalize on the assets of other organizations through vertical and horizontal linkages. The second, interfirm knowledge transfer, occurs between buyers, industry cohorts and entrepreneurial partners. It allows firms to experiment with new procedures, and compare their results with other firms'. The third, novel combination of information and inputs, enables firms to take advantage of their flexibility and creativity to quickly identify alternative courses of action, thus avoiding failure. The implication of these findings for firms is that those who exhibit the three characteristics above are more likely to be successful at shifting to VA production than those who do not. The implications for business associations is that they must play a key role by keeping the necessary information flowing through a network that has vertical and horizontal exchanges. The implication for the state is a role of economic stabilization and sustenance of a legal and business environment supportive of private enterprise, as well as working with local firms to help them gain entry into market networks.

description: We solve, for finite $N$, the matrix model of supersymmetric $U(N)$ Chern-Simons theory coupled to $N_{f}$ massive hypermultiplets of $R$-charge $\frac{1}{2}$, together with a Fayet-Iliopoulos term. We compute the partition function by identifying it with a determinant of a Hankel matrix, whose entries are parametric derivatives (of order $N_{f}-1$) of Mordell integrals. We obtain finite Gauss sums expressions for the partition functions. We also apply these results to obtain an exhaustive test of Giveon-Kutasov (GK) duality in the $\mathcal{N}=3$ setting, by systematic computation of the matrix models involved. The phase factor that arises in the duality is then obtained explicitly. We give an expression characterized by modular arithmetic (mod 4) behavior that holds for all tested values of the parameters (checked up to $N_{f}=12$ flavours).

A tight universal relation between the shape eccentricity and the moment of inertia for rotating neutron stars

description: Universal relations that are insensitive to the equation of state (EoS) are useful in reducing the parameter space when measuring global quantities of neutron stars (NSs). In this paper, we reveal a new universal relation that connects the eccentricity to the radius and moment of inertia of rotating NSs. We demonstrate that the universality of this relation holds for both conventional NSs and bare quark stars (QSs) in the slow rotation approximation, albeit with different relations. The maximum relative deviation is approximately $1\%$ for conventional NSs and $0.1\%$ for QSs. Additionally, we show that the universality still exists for fast-rotating NSs if we use the dimensionless spin to characterize their rotation. The new universal relation will be a valuable tool to reduce the number of parameters used to describe the shape and multipoles of rotating NSs, and it may also be used to infer the eccentricity or moment of inertia of NSs in future X-ray observations.

description: By using non-equilibrium molecular dynamics simulations(NEMD), the modulation on temperature dependence of thermal conductivity of graphene phononic crystals (GPnCs) are investigated. It is found that the temperature dependence of thermal conductivity of GPnCs follows $T^{-α}$ behavior. The power exponents ($α$) can be efficiently tuned by changing the characteristic size of GPnCs. The phonon participation ratio spectra and dispersion relation reveal that the long-range phonon modes are more affected in GPnCs with larger size of holes ($L_0$). Our results suggest that constructing GPnCs is an effective method to manipulate the temperature dependence of thermal conductivity of graphene, which would be beneficial for developing GPnCs-based thermal management and signal processing devices.

Lindblad dynamics of a quantum spherical spin

description: The coherent quantum dynamics of a single bosonic spin variable, subject to a constraint derived from the quantum spherical model of a ferromagnet, and coupled to an external heat bath, is studied through the Lindblad equation for the reduced density matrix. Closed systems of equations of motion for several quantum observables are derived and solved exactly. The relationship to the single-mode Dicke model from quantum optics is discussed. The analysis of the interplay of the quantum fluctuation and the dissipation and their influence on the relaxation of the time-dependent magnetisation leads to the distinction of qualitatively different regimes of weak and strong quantum couplings. Considering the model's behaviour in an external field as a simple mean-field approximation of the dynamics of a quantum spherical ferromagnet, the magnetic phase diagramme appears to be re-entrant and presents a quantum analogue of well-established classical examples of fluctuation-induced order.

Implementing Grocery Cooperatives in Low-Income Communities: Case Example of the Renaissance Community Cooperative in Greensboro, North Carolina

description: Over the last few decades, the U.S. food retail environment has experienced a significant evolution in the means by which it delivers product to consumers. Food retail innovation has bred new models of food delivery that attempt to improve convenience while recognizing the need to meet existing and emerging consumer preferences. For example, a growing subset of U.S. consumers
are interested in consuming local, organic and natural foods for environmental, ethical, health and other plausible reasons. As a result, an increasing number of farm to consumer delivery models, such as community-supported agriculture (CSA) programs and farmers markets, have emerged to meet the demand of niche markets. In fact, within a 10-year period (1998-2009) the number of farmers
markets increased by 92% to well over 5,000 across the U.S. and since 1986 the number of CSA programs increased from two to over 1,000. For another subset of the population, food preferences are less choice-driven and are essentially determined by income levels. Since affordable community-supported agriculture programs and farmers markets are not commonplace in many low-income communities, low-income consumers reply largely on free food pantries, convenience stores and fast food restaurants. None of these options generally offer healthy food options, relative to the food retail options available to consumers with higher incomes. Income therefore is the first key indicator underlying access to healthy food. Even as the number and variety of food retail options available to most consumers have risen in recent years, there is tremendous variability in access of different populations to good, healthy and affordable food based on how much they are able to pay.

Mass ejection by pulsational pair instability in very massive stars and implications for luminous supernovae

description: Massive stars having a CO core of $\sim$40-60 M$_\odot$ experience pulsational pair-instability (PPI) after carbon-burning. This instability induces strong pulsations of the whole star and a part of outer envelope is ejected. We investigate the evolution and mass ejection of metal-poor very massive stars which experience PPI. We use stellar models with initial masses of 140, 200, and 250 M$_\odot$ and the metallicity Z=0.004. Their masses decrease to 54.09, 58.65, and 61.03 M$_\odot$ before the neon-burning owing to mass-loss and He mass fraction at the surface becomes about 20%. During the PPI period of $\sim$1-2000 yr, they experience six, four, and three pulsations, respectively. The larger CO-core model has the longer PPI period and ejects the larger amount of mass. Since almost all surface He has been lost by the pulsations, these stars become Type Ic supernovae if they explode. Light curves during the PPI stage and supernovae are investigated and are implicated in luminous supernovae. The luminosity created by the interaction of different PPI ejecta becomes $M_{\rm bol} \sim -16$ to $-20$. The interaction between the circumstellar shell ejected by PPI and the supernova ejecta can be more luminous. These luminous transients could be an origin of Type I superluminous supernovae and supernovae with precursor.

description: Vortex lattices in rapidly rotating Bose-Einstein condensates lead to a periodic modulation of the superfluid density with a triangular symmetry. Here we show that this symmetry can be combined with an external perturbation in order to create super-lattice structures with two or more periodicities. Considering a condensate which is kicked by an optical lattice potential, we find the appearance of transient moiré lattice structures, which can be identified using the kinetic energy spectrum.
