Telecommuting: Working From Home in the 21st Century
Creators: name: Wernick, Steven
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004
Subjects: Telecommuting

description: Telecommuting is an emerging phenomenon in the United States, as an alternative to the daily commute. Pushing forward the frontier of research on telecommuting behavior, this paper looked at data from the 2001 National Household Travel Survey (N=25,432) to analyze relationships between socioeconomic and household variables, travel characteristics, technological characteristics and the proclivity to telecommute. Most importantly, ownership of and access to telecommunications were looked at for the first time on a national scale. Overall, the number of people telecommuting has remained low. Only 9.5% of respondents reported engaging in telecommuting, with 5.2% working from home frequently and 4.3% of respondents working from home infrequently. Statistical analysis involves estimation of binary logistic regression models and ordered logit models to look at the effects of independent variables on 2 dependent variables (telecommuting and frequency of telecommuting). Similar results were obtained using both variables. Telecommuting was positively associated with respondents who were male, had higher levels of education, higher household incomes, a greater number of telephones in the house, access to the internet from both home and work, access to rail, and had greater distances to travel to work. Age, household type, and CMSA also had positive relationships with working from home. Conversely, working full-time and a greater number of household vehicles had an adverse effect on telecommuting. Results of the analysis suggest that policies that succeed in increasing level of education and income will have positive effects on telecommuting. Additionally, greater market penetration of telecommunications may lead to the adoption of telecommuting as a real alternative to the traditional workplace. As high-speed internet access and wireless communication devices become more prevalent, Americans will have greater ability to communicate from home to the workplace.

description: Through the use of market studies looking at various indicators of supply and demand, firms are continually attempting to predict future investment opportunities. While most of these studies rely primarily on measures of economic growth, this market study utilizes the use of another dimension by including measures of economic development. By including this additional indicator, this study seeks to inform The Generation Companies, a real estate development and operating firm based in Durham, North Carolina, in regards to markets of interests for future investments. As a part of this study, economic growth and economic development indicators representing the demand side were weighted and combined with a regulation on supply indicator in order to create a final investment index for 65 metropolitan areas within 9 states of the eastern United States. In getting to this final index the data suggests at least two patterns; one being that larger university towns are more regulated than the other towns and second being that generally metro areas with larger populations have higher total investment indices. In terms of results pertaining to The Generation Companies, it was found that their current investments are very sound in relation to our final investment index. In fact of the 20 hotels in which they own or manage within the study metro areas, 13 or 65% of them are located in the top third of our final investment rankings. Overall, it is thought that though the inclusion of economic development indicators, which are uncommon to traditional market studies, this study should provide great insight and assistance in the future investment decisions for The Generation Companies.

description: We study theoretically electromagnetic radiation emitted by inelastic Cooper-pair tunneling. We consider a dc-voltage-biased superconducting transmission line terminated by a Josephson junction. We show that the generated continuous-mode electromagnetic field can be expressed as a function of the time-dependent current across the Josephson junction. The leading-order expansion in the tunneling coupling, similar to the "$P(E)$-theory", has previously been used to investigate the photon emission statistics in the limit of sequential (independent) Cooper-pair tunneling. By explicitly evaluating the system characteristics up to the fourth-order in the tunneling coupling, we account for dynamics between consecutively tunneling Cooper pairs. Within this approach we investigate how temporal correlations in the charge transport can be seen in the first- and second-order coherences of the emitted microwave radiation.

description: Non-Hermitian systems have been widely explored in platforms ranging from photonics to electric circuits. A defining feature of non-Hermitian systems is exceptional points (EPs), where both eigenvalues and eigenvectors coalesce. Tropical geometry is an emerging field of mathematics at the interface between algebraic geometry and polyhedral geometry, with diverse applications to science. Here, we introduce and develop a unified tropical geometric framework to characterize different facets of non-Hermitian systems. We illustrate the versatility of our approach using several examples, and demonstrate that it can be used to select from a spectrum of higher-order EPs in gain and loss models, predict the skin effect in the non-Hermitian Su-Schrieffer-Heeger model, and extract universal properties in the presence of disorder in the Hatano-Nelson model. Our work puts forth a new framework for studying non-Hermitian physics and unveils a novel connection of tropical geometry to this field.

Dorothea Dix Hospital: Center Building Reuse Study
Creators: name: Nicholas, D. Chase
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: At the time of this writing, a visitor to Dix Park would find little evidence of the park’s pending transformation. The vast landscape remains relatively pristine, without earthmovers, cranes, or the droning of drills and hammers. Yet this early stage is humming with mental activity, the proliferation of ideas, and the conceptualization of a new place. The ground is long broken on the construction of a new vision for these 306-acres. At the heart of the park is the Center Building, the original hospital building and key historic resource on the 306-acre park. The fate of the Center Building remains, like the entirety of the Park, the subject of discussion and speculation. This report attempts to add rigor and perspective to this discussion through research and modelling. This report argues for preservation and attempts to disentangle some of the complexity of an adaptive reuse project for the building. It is the intention of the author that this report will augment ongoing park visioning activities and serve as both a reference and point of conversation for those involved in the planning of the park and preservation of its real estate. This report concludes with a hypothetical model of reuse intended as a demonstration of feasibility. This model one of many reuse scenarios that could bring new life to the Center Building. The purpose of the model proposed here is not to stymie alternative ideas, but to serve as a springboard for them. This report begins with a summary of background information about the park and the Center Building that will be relevant to decisions about the building’s reuse. This section includes relevant planning and market conditions in downtown Raleigh. The middle section of this report offers three case studies of similar reuse projects on large, urban campuses, with an emphasis on core projects and their uses. The final section of this report is a hypothetical model of an adaptive reuse project for the Center Building that focuses on compatibility and feasibility. The report concludes with recommendations for planning efforts for the Center Building, regardless of the ultimate reuse scenario.

Back To Basic: Addressing Veteran reintegration into the civilian workforce
Creators: name: Ziemke, Marcus
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: As Veterans of America’s military return to the civilian workforce, evidence of
significant barriers have led to disproportionate unemployment rates for Veterans, especially in
the age range of 18-24. Studies have indicated that many Veterans show a lack of job attainment
skills, a lack of civilian certifications and licensing, and insufficient transition assistance. To
address these issues, programs and initiatives have been implemented to assist the reintegration
of Veterans into the workforce. Common attributes of these programs can be grouped into two
categories, job linkage programs, or education and development programs.
Although success has been found with these programs, the Vocational Rehabilitation
Program has shown that success has been possible with a comprehensive program that
incorporates both job linkage and development, as well as providing resources for health care.
The costs per participants also indicates that the cost-effectiveness is similar to other programs
while addressing more Veteran issues.

description: For a large class of mass-varying massive gravity models, the graviton mass cannot provide the late-time cosmic expansion of the universe due to its vanishing at late time. In this work, we propose a new class of mass-varying massive gravity in which the graviton mass varies according to a kinetic term of a k-essence field. By using a more general form of the fiducial metric, we found a solution such that a non-vanishing graviton mass can drive the accelerated expansion of the universe at late time. We also perform dynamical analyses of such model and found that without introducing the k-essence Lagrangian, the graviton mass can be responsible for both dark contents of the universe, namely dark energy that drives the accelerated expansion of the universe and non-relativistic matter that plays the role of dark matter. Moreover, by including the k-essence Lagrangian, we found that it is possible to alleviate the so-called cosmic coincidence problem.

Getting people "on the bus": an analysis of the successful marketing of small transit systems
Creators: name: Patrone, Anne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: As planners, we often find ourselves trying to entice the public to change their behaviors in order to provide an environment more conducive to good planning practices. The Town of Chapel Hill has made a commitment not to widen or add roads, despite the inevitable growth in both population and jobs. Chapel Hill Transit will help share the burden of new traffic to the area, but its profile in the community will need to rise. What convinces the public to utilize public transportation? Strict parking restrictions and high transportation costs ensure that people have no other alternative but to use transit, and Chapel Hill Transit has supported the university and hospital population well. But what about those sectors of the population that are not being captured by these regulations - those people living in Chapel Hill Transit's service area who do not have to utilize the transit system daily? How can they be made aware of the services Chapel Hill Transit provides to their neighborhoods and be enticed to use the system? The existence of a generally highly educated, liberal, and environmentally conscious public seems to provide favorable conditions for a transit system to thrive. How can this public be encouraged to use public transit more frequently? The purpose of this project is to establish a set of best practices for the marketing of small transit systems, by examining several case studies of similar transit systems to Chapel Hill Transit. The conclusions drawn from these case studies will then provide the basis for recommendations to Chapel Hill Transit on how to best market their services and how to reach the larger communities of Carrboro and Chapel Hill.
Pedal to the metal: bicycle-transit integration in San Francisco: existing conditions, needs, and recommendations for Polk Street

description: A review of citywide policies, programs, and plans related to bicycling and transit provides the background for a corridor study of Polk Street. Existing conditions are reported and synthesized to identify needs. A literature review revealed four main strategies for integration; these were used to produce a set of recommendations. Two classes of recommendations were provided: "ideal" and "critical," reflecting a desire to create an exemplary bicycle-transit integrated street but also to entertain those improvements that are most feasible. The study was guided by four goals: (1) to improve bicyclist and pedestrian safety near transit, (2) to alleviate congestion on crowded transit vehicles, (3) to increase bicycle and transit mode share, and (4) to prioritize transit reliability.

description: The optical classification of a Seyfert galaxy and whether it is considered X-ray absorbed are often used interchangeably. But there are many borderline cases and also numerous examples where the optical and X-ray classifications appear to be in conflict. In this article we re-visit the relation between optical obscuration and X-ray absorption in AGNs. We make use of our "dust color" method (Burtscher et al. 2015) to derive the optical obscuration A_V and consistently estimated X-ray absorbing columns using 0.3--150 keV spectral energy distributions. We also take into account the variable nature of the neutral gas column N_H and derive the Seyfert sub-classes of all our objects in a consistent way. We show in a sample of 25 local, hard-X-ray detected Seyfert galaxies (log L_X / (erg/s) ~ 41.5 - 43.5) that there can actually be a good agreement between optical and X-ray classification. If Seyfert types 1.8 and 1.9 are considered unobscured, the threshold between X-ray unabsorbed and absorbed should be chosen at a column N_H = 10^22.3 / cm^2 to be consistent with the optical classification. We find that N_H is related to A_V and that the N_H/A_V ratio is approximately Galactic or higher in all sources, as indicated previously. But in several objects we also see that deviations from the Galactic ratio are only due to a variable X-ray column, showing that (1) deviations from the Galactic N_H/A_V can simply be explained by dust-free neutral gas within the broad line region in some sources, that (2) the dust properties in AGNs can be similar to Galactic dust and that (3) the dust color method is a robust way to estimate the optical extinction towards the sublimation radius in all but the most obscured AGNs.

The Role That Volunteer Monitoring Plays In Watershed Planning and An Evaluation of the USDA Stream Visual Assessment Protocol In the Booker Creek Watershed
Creators: name: Edmonson, Christine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Volunteer stream and water quality monitoring is increasing throughout the country and the use of volunteer data is growing. Volunteers are collecting data on the chemical and biological conditions of streams, in addition to the physical conditions in a watershed. This information may be used to establish a baseline characterization of a watershed or to monitor changes in stream health over time. It may also be used to identify pollution sources or to make land use planning decisions within a watershed. The extent to which volunteer monitoring data is used by planning agencies at both the state and local levels is, however, unclear. This study seeks to determine how much of the regularly collected data by volunteers is used to make watershed planning decisions. To assess the role that volunteer monitoring plays in watershed planning, I will first discuss the history and application of voluntarily collected data by drawing on the literature. I then place this in context in the Chapel Hill area by exploring local monitoring and watershed planning efforts. Finally, I apply the USDA Stream Visual Assessment Protocol to Booker Creek and evaluate it as a method for planners to use to assess watershed health.

Design, policy, and bicycle ridership: a comparison between Berlin, Germany and Washington D.C.
Creators: name: Bushell, Max
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: While some research has been completed with regard to the effect of bicycle infrastructure on bicycle ridership levels, little has been done comparing the institutional structure as well as the design elements for bicycles between Germany and the United States. Germany, among other western European nations, has incorporated bicycle infrastructure on many of their streets in the form of bicycle lanes and bicycle stoplights. In Berlin, the capital city of Germany, the bicycle is considered throughout the city in terms of infrastructure. In Washington D.C., the capital of the United States, bicycle infrastructure, while becoming more prevalent in the city in the form of on-street bicycle lanes, is often still insufficient or lacking entirely. While a comparison between the ridership levels within the two cities is the primary design of this analysis, I will also conduct an analysis of ridership levels between the two cities to gain a better understanding of how policy affects bicycle ridership. The combination of favorable bicycle policy, discouragement of automobile transportation, and investment in bicycle infrastructure can create a bicycle friendly city and increase bicycle ridership in urban areas. In this paper, I plan to elucidate the design and policy elements that have created Berlin as an extremely bicycle-friendly city and Washington D.C. as a city in need of better bicycling facilities. I will outline various street design elements and policies in the United States and in Germany in relation to bicycling. Following this basic analysis, I will establish the basis for my comparison between the cities, present tables of bicycle ridership in both cities, analyze this data, and conclude with my results. My recommendations are to create a national bicycle policy, include a provision for street purpose in the functional classification of streets, and increase the right-of-way dedicated to pedestrians and bicycles.

description: Context. The analysis of observations of circumstellar disks around young stellar objects is often based on models with a smooth and continuous density distribution. However, spatially resolved observations with increasing angular resolution and dynamical models indicate that circumstellar disks are highlystructured. Aims. We investigate the influence of different clumpy density distributions on selected physical properties and observable characteristics of circumstellar disks. Methods. Based on radiative transfer modelling we calculate the temperature structure of the disk and simulate observational quantities in the thermal re-emission and scattering regime. We compare our results to those obtained for a smooth and continuous density distribution to quantify the influence of clumps on physical parameters and observable quantities of circumstellar disks. Results. Within the considered model space, the clumpiness has a significant impact on the disk temperature distribution. For instance, in the transition region from the upper disk layers to the disk interior, it causes a decrease of the mean temperature by up to 12 K. In addition, circumstellar disks with clumpy density distributions feature a lower spectral index in the submm/mm range of the SED. As a consequence of the lower spectral index, the dust grain size derived from the submm/mm-slope of the SED may be overestimated, if the inhomogeneity of the disk density distribution is not taken into account. Furthermore, the scattered light brightness distribution of clumpy disks shows a steeper radial decrease. Additionally, clumpy density distributions change the degree of polarization of the scattered light in the optical.

Walltown: The History of A Neighborhood and A Housing Renovation Program
Creators: name: Deutsch, Heather
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Walltown is a small neighborhood located in downtown Durham, North Carolina near the prestigious, Duke University. Plagued by crime and high vacancy rates for decades, in 1996 Self-Help, a financial institution focusing on increasing assets for low-income borrowers, commenced a large scale housing renovation program. This paper presents a case study of the neighborhood. The first part of the paper is a history of the neighborhood which began as an enclave of predominately African-Americans employed at Duke and the neighboring tobacco mills, endured substantial decline and vacancy beginning in the 1970's, and attracted the attention of a non-profit, the Center for Community Self-Help, who become involved in a housing renovation project in the neighborhood. The second part of the paper presents the details of Self-Help's housing renovation program, including the costs of renovation, financing, marketing, the barriers Self-Help encountered, and how they overcame them. The intent of this paper is to aid non-profit and for-profit developers and municipalities in understanding how to successfully implement a housing renovation program in similar neighborhoods. It is also hoped that by showing the barriers to such programs steps can be taken to eradicate the barriers, making these programs more viable in the future. The Walltown neighborhood is bounded by Clarendon Street, Guess Road, Buchanan Boulevard, and Green Street. It lies north of Duke University's East Campus, south-west of Northgate Mall, and between the Trinity Park and Watts-Hillandale neighborhoods.
Case Study on Invasive Hippos in Columbia

description: Columbia has a hippopotamus problem. Pablo Escobar brought the hippopotamus to Columbia and after his capture they were released to the wild. Now they present a bigger problem to the ecosystem. In this case study, students first compare the Columbian rainforest to the African Savannah in terms of what controls the hippopotamus. Students then graph the growing population and discuss the damage to ecosystem that is being done by the hippos and what some possible solutions might be.
Hawking radiation, the Stefan-Boltzmann law, and unitarization

description: Where does Hawking radiation originate? A common picture is that it arises from excitations very near or at the horizon, and this viewpoint has supported the "firewall" argument and arguments for a key role for the UV-dependent entanglement entropy in describing the quantum mechanics of black holes. However, closer investigation of both the total emission rate and the stress tensor of Hawking radiation supports the statement that its source is a near-horizon quantum region, or "atmosphere," whose radial extent is set by the horizon radius scale. This is potentially important, since Hawking radiation needs to be modified to restore unitarity, and a natural assumption is that the scales relevant to such modifications are comparable to those governing the Hawking radiation. Moreover, related discussion suggests a resolution to questions regarding extra energy flux in "nonviolent" scenarios, that does not spoil black hole thermodynamics as governed by the Bekenstein-Hawking entropy.

Efficient Gradient Approximation Method for Constrained Bilevel Optimization

Subjects: subject: Machine Learning (cs.LG)

description: Bilevel optimization has been developed for many machine learning tasks with large-scale and high-dimensional data. This paper considers a constrained bilevel optimization problem, where the lower-level optimization problem is convex with equality and inequality constraints and the upper-level optimization problem is non-convex. The overall objective function is non-convex and non-differentiable. To solve the problem, we develop a gradient-based approach, called gradient approximation method, which determines the descent direction by computing several representative gradients of the objective function inside a neighborhood of the current estimate. We show that the algorithm asymptotically converges to the set of Clarke stationary points, and demonstrate the efficacy of the algorithm by the experiments on hyperparameter optimization and meta-learning.

description: We compare the science capabilities of different eLISA mission designs, including four-link (two-arm) and six-link (three-arm) configurations with different arm lengths, low-frequency noise sensitivities and mission durations. For each of these configurations we consider a few representative massive black hole formation scenarios. These scenarios are chosen to explore two physical mechanisms that greatly affect eLISA rates, namely (i) black hole seeding, and (ii) the delays between the merger of two galaxies and the merger of the black holes hosted by those galaxies. We assess the eLISA parameter estimation accuracy using a Fisher matrix analysis with spin-precessing, inspiral-only waveforms. We quantify the information present in the merger and ringdown by rescaling the inspiral-only Fisher matrix estimates using the signal-to-noise ratio from non-precessing inspiral-merger-ringdown phenomenological waveforms, and from a reduced set of precessing numerical relativity/post-Newtonian hybrid waveforms. We find that all of the eLISA configurations considered in our study should detect some massive black hole binaries. However, configurations with six links and better low-frequency noise will provide much more information on the origin of black holes at high redshifts and on their accretion history, and they may allow the identification of electromagnetic counterparts to massive black hole mergers.
