description: There are two essays in this dissertation. In the first chapter, I first build a model to investigate firms’ earnings management behavior and the bargaining process between firms and unions. The outcome for bargaining is specified by Nash Bargaining solutions and firms have incentives to report lower earnings after unionization to prevent unions from demanding high wages, pensions, and other benefits. In the same spirit as Stein (1989), in equilibrium, firms’ earnings management incentive is anticipated and adjusted for by the union and the market. However, firms cannot commit not to do earnings management ex-ante. Empirically, I employ the data on union elections to verify predictions from the model. Compared with firms that just fail to pass the unionization with a small margin of votes around 50%, those who just pass engage in significantly less earnings management. For firms that barely pass the election, the pre-determined firm characteristics one year before unionization are not significantly different from those that just fail to pass. I do not find any evidence that unionized firms conduct significantly less earnings management before unionization. The main result that firms’ earnings management is significantly lower for firms just above the cutoff is robust and not spurious. In summary, I document robust evidences on the causal effect of unionization on earnings management. Regarding the second chapter, “Incentive Contracting with Multiple Directorships”, I focus on a feature of the outside director market, that is, a director can simultaneously work for several companies. I build a model to investigate the relationship between incentives (Pay-Performance Sensitivity) that are offered by different companies and the number of directorships an outside director holds. Theoretically, I find that the relationship between optimal incentives (Pay-Performance- Sensitivity) and the number of directorships is always positive, no matter efforts across directorships are substitutive or complementary.

Determinism in GPU Programs - Real Time Applications on the NVIDIA Jetson TK1
Creators: name: Miller, Vance
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In recent years, increases in computing power have reached the automotive industry in the form of advanced driver assistance systems (ADAS). Cars that support these systems require
a variety of sensors and powerful computers. Sensor data must be processed and acted upon in real time so that the car can react to changes in its environment as they occur. This is especially important when the car must take action to avoid a collision and potentially prevent loss of life. GPUs offer a large speedup for processing sensor data but their runtime performance can be unpredictable in some cases. In this paper we evaluate the predictability of GPU programs on the NVIDIA Jetson TK1 and make them perform more
predictably by using Zero Copy memory.

Prekäre Integration. Die Folgen unsicherer Beschäftigungsverhältnisse
Creators: name: Magnin, Chantal
Publisher: name: Zenodo
Year: 2005

description: Ausgehend von der Darlegung des Forschungsdesigns eines laufenden qualitativen Forschungsprojektes zum Wandel der Arbeitswelt in der Schweiz (work in progress) wird der Frage nachgegangen, wie sich prekäre Beschäftigung und soziale Integration soziologisch begrifflich fassen lassen. Dies beinhaltet auch die Klärung der Frage, inwiefern die beiden analytisch von einander losgelöst zu betrachtenden Aspekte in der soziologischen Betrachtung unweigerlich zusammenhängen. Diese theoretischen Erörterungen mit dem Ziel einer Problematisierung des Untersuchungsgegenstandes werden in die Skizzierung der eingenommenen Forschungsperspektive und des auf die spezifische Arbeitsmarktsituation in der Schweiz gerichteten Fokus überleiten. Der dortige Wandel drückt sich insbesondere in einer seit anfangs der 1990er Jahre für die Schweiz konstant hohen Arbeitslosenquote aus. Auch gilt es, eine Zunahme von „working poor“ zu verzeichnen. Dagegen ist das Verhältnis von zeitlich unbefristeten und befristeten Beschäftigungsverhältnissen nahezu konstant geblieben, anders als in Ländern mit gutem Kündigungsschutz wie zum Beispiel in Frankreich und Italien. Nichtsdestotrotz ist die Unsicherheit allgegenwärtig, die Angst vor Stellenverlust relativ verbreitet. Ziel des zu präsentierenden qualitativen Forschungsprojektes ist es herauszufinden, welche Bewältigungsstrategien prekär beschäftigte Personen angesichts ihrer allenfalls damit verbundenen Probleme entwickeln und auf welche Deutungsressourcen und Kompetenzen sie dabei zurückgreifen. Anhand einer Fallanalyse soll die Rekonstruktion einer solchen Handlungsstrategie verdeutlicht werden. Dabei gelangt auch das in diesem Fall spezifisch wirksame Ausgrenzungsrisiko zum Ausdruck.

An Assessment of Marine Hydrokinetic (MHK) Energy in the Gulf Stream off Cape Hatteras, North Carolina
Creators: name: Lowcher, Caroline Ford
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The Gulf Stream is the western boundary current of the North Atlantic subtropical gyre, and it flows for part of its course just offshore of the southeastern US coastline.  This large-scale ocean current has current velocities reaching approximately 2 m s-1, which distinguish it as a potential source of marine hydrokinetic (MHK) energy.  The upper continental slope off Cape Hatteras is a desirable area for development of offshore renewable energy because of the narrowness of the continental shelf and the Stream’s minimal meanderings there.  Using current data from a moored 150 kHz acoustic Doppler current profiler (ADCP) and from the Mid-Atlantic Bight and South Atlantic Bight (MABSAB) regional ocean circulation model, MHK power characteristics have been computed for this area. These calculations quantify the Gulf Stream power resource and its temporal and spatial variations.  During August 2013 – April 2014 at the moored ADCP site and 75 m below the ocean surface, which was within the Gulf Stream’s cyclonic shear zone, a comparison of the ADCP and MABSAB model currents reveals that the average current speeds from the two sources are nearly identical, with a magnitude of 0.94 m s-1.  A comparison for the same time period was made for the current’s power density.  The ADCP-observed average was 798 W m-2, and the model average was 641 W m-2, a difference of about 20%.  The model has shown to have similar current speeds to the ADCP for slowly varying currents (fluctuations of weeks to months), and lower speeds for higher frequency current variations (fluctuations of several days to a couple of weeks).  The model also shows somewhat less variability than the ADCP in directionality of the Stream’s flow.  Model data have been used to calculate the annual power density averages for a number of years at various locations within the Gulf Stream over the North Carolina continental slope.  These results show the variation of the Stream's position along the North Carolina coastline over 2009-2013, and show that yearly averaged power at a given location has significant inter-annual variations.  This holds true for the ADCP location where the model has an average power of 14 W m-2 in 2010 and an average power of 1,055 W m-2 in 2012.

description: We analyse by numerical simulations and scaling arguments the avalanche statistics of 1-dimensional elastic interfaces in random media driven at a single point. Both global and local avalanche sizes are power-law distributed, with universal exponents given by the depinning roughness exponent $ζ$ and the interface dimension $d$, and distinct from their values in the uniformly driven case. A crossover appears between uniformly driven behaviour for small avalanches, and point driven behaviour for large avalanches. The scale of the crossover is controlled by the ratio between the stiffness of the pulling spring and the elasticity of the interface; it is visible both in the global and local avalanche-size distributions, as in the average spatial avalanche shape. Our results are relevant to model experiments involving locally driven elastic manifolds at low temperatures, such as magnetic domain walls or vortex lines in superconductors.

The Impact of Personality on Team Cohesion and Performance
Creators: name: Malmberg, Marta
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The use of teams in the workplace has become a pivotal method of completing challenging tasks.  The present research examined data from 95 participants across 18 teams and found that certain personality traits, as measured by the Myers-Briggs Type Indicator (MBTI), have shown correlation with team performance.  The teams were composed of undergraduate and MBA students working together in semester-long consulting projects.  Each team was assigned one project leader who was an MBA student with additional experience.  The research showed that teams led by a project leader with the thinking preference of the MBTI correlated with higher team performance scores.  Higher team performance scores were also correlated with higher team cohesion scores.  In addition, having heterogeneity of certain personality types was not found to be more conducive for team cohesion and performance.  All four dichotomies of the MBTI were analyzed to identify additional correlated elements of team cohesion and performance.

Gleichzeitig erhob sie die Bedürfnisse dieser Zielgruppe. Die Studie diente dazu, einen Überblick darüber zu erhalten, ob der Zugang zu Informationen und Hilfsangeboten für Menschen mit einer kognitiven Beeinträchtigung im Sinne der gesundheitlichen Chancengleichheit gewährleistet ist. Ein zentraler Befund weist die Notwendigkeit aus, die Zielgruppe zukünftig direkt zu adressieren. Ein passender Weg hierzu ist aus Sicht der von uns Befragten die Erstellung digitaler Formate, um sich selbstbestimmt und ohne fremde Hilfe Informationen zu sexualitätsbezogenen Themen zu erschliessen.

Two Higgs doublet model with vectorlike leptons and contributions to $pp\to WW$ and $H\to WW$

description: We study a two Higgs doublet model extended by vectorlike leptons mixing with one family of standard model leptons. Generated flavor violating couplings between heavy and light leptons can dramatically alter the decay patterns of heavier Higgs bosons. We focus on $pp \to H \to ν_4 ν_μ\to W μν_μ$, where $ν_4$ is a new neutral lepton, and study possible effects of this process on the measurements of $pp \to WW$ and $H \to WW$ since it leads to the same final states. We discuss predictions for contributions to $pp \to WW$ and $H \to WW$ and their correlations from the region of the parameter space that satisfies all available constraints including precision electroweak observables and from pair production of vectorlike leptons. Large contributions, close to current limits, favor small $\tan β$ region of the parameter space. We find that, as a result of adopted cuts in experimental analyses, the contribution to $pp \to WW$ can be an order of magnitude larger than the contribution to $H \to WW$. Thus, future precise measurements of $pp\to WW$ will further constrain the parameters of the model. In addition, we also consider possible contributions to $pp\to WW$ from the heavy Higgs decays into a new charged lepton $e_4$ ($H\to e_4 μ\to W μν_μ$), exotic SM Higgs decays, and pair production of vectorlike leptons.

The Effects of Different Types of Childbirth Experiences in White, Middle Class Women in Western North Carolina
Creators: name: Minish, Bailey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: American women are increasingly choosing alternatives to a traditional physician-assisted hospital delivery to give birth. According to the U.S. Centers for Disease Control and Prevention (CDC), midwives assisted 8.1% of total births and 12.1% of vaginal births in 2009, the highest it’s been since the movement of childbirth from the home into hospitals in the first half of the 20th century (Rochman 2012). In the US, the percentage of out-of-hospital births grew from 1.26% in 2011 to 2.36% in 2012, continuing a trend that has become increasingly popular since 2004 (MacDorman et. al 2014). Compare that to a whopping 2.4% of homebirths that occurred in Buncombe County, the heart of the mountains of Western North Carolina, in 2011 (Ball 2013).
This thesis surveys mothers in Western North Carolina from two generations to discover how women’s perceptions of options have changed over time and how they make their decisions or acquire expectations regarding birth. Women with a variety of childbirth experiences, including traditional hospital birth, birth assisted by a midwife, and an accidental homebirth, were interviewed allowing for the analysis of variation in perception of a positive experience amongst women who had different types of birth experiences.

description: Community involvement and the preventive behavior of households are considered to be at the heart of vector-control strategies. In this work, we consider a simple theoretical model that enables us to take into account human behaviors that may interfere with vector control. The model reflects the trade-off between perceived costs and observed efficacy. Our theoretical results emphasize that households may reduce their protective behavior in response to mechanical elimination techniques piloted by a public agent, leading to an increase of the total number of mosquitoes in the surrounding environment and generating a barrier for vector-borne diseases control. Our study is sufficiently generic to be applied to different arboviral diseases. It also shows that vector-control models and strategies have to take into account human behaviors.

We present exact analytic expressions for entanglement end Renyi entropies between arbitrary number of scalar fields by which we could explore certain entanglement inequalities. Other entanglement measures such as mutual information and entanglement negativity have also been studied. We also give some comments about possible holographic realizations of such models.

description: Background

We evaluated time-varying perinatal risk factors associated with early (≤7 post-natal days) and late (>7 post-natal days) severe acute kidney injury (AKI) occurrence and duration.
Methods

A secondary analysis of Preterm Erythropoietin Neuroprotection Trial data. We defined severe AKI (stage 2 or 3) per neonatal modified Kidney Disease: Improving Global Outcomes criteria.

Adjusted Cox proportional hazards models were conducted with exposures occurring at least 72 h before severe AKI. Adjusted negative binomial regression models were completed to evaluate risk factors for severe AKI duration.
Results

Of 923 participants, 2% had early severe AKI. In the adjusted model, gestational diabetes (adjusted HR (aHR) 5.4, 95% CI 1.1–25.8), non-steroidal anti-inflammatory drugs (NSAIDs) (aHR 3.2, 95% CI 1.0–9.8), and vancomycin (aHR 13.9, 95% CI 2.3–45.1) were associated with early severe AKI.

Late severe AKI occurred in 22% of participants. Early severe AKI (aHR 2.5, 95% CI 1.1–5.4), sepsis (aHR 2.5, 95% CI 1.4–4.4), vasopressors (aHR 2.9, 95% CI 1.8–4.6), and diuretics (aHR 2.6, 95% CI 1.9–3.6) were associated with late severe AKI.

Participants who had necrotizing enterocolitis or received NSAIDs had longer severe AKI duration.
Conclusion

We identified major risk factors for severe AKI that can be the focus of future research.
Impact statement

    Time-dependent risk factors for severe acute kidney injury (AKI) and its duration are not well defined among infants born <28 weeks’ gestation.

    Over 1 in 5 infants born <28 weeks’ gestation experienced severe AKI, and this study identified several major time-dependent perinatal risk factors occurring within 72 h prior to severe AKI.

    This study can support efforts to develop risk stratification and clinical decision support to help mitigate modifiable risk factors to reduce severe AKI occurrence and duration.
A Bioluminescence Resonance Energy Transfer-Based Approach for Determining Antibody-Receptor Occupancy In Vivo

description: Elucidating receptor occupancy (RO) of monoclonal antibodies (mAbs) is a crucial step in characterizing the therapeutic efficacy of mAbs. However, the in vivo assessment of RO, particularly within peripheral tissues, is greatly limited by current technologies. In the present study, we developed a bioluminescence resonance energy transfer (BRET)-based system that leverages the large signal:noise ratio and stringent energy donor-acceptor distance dependency to measure antibody RO in a highly selective and temporal fashion. This versatile and minimally invasive system enables longitudinal monitoring of the in vivo antibody-receptor engagement over several days. As a proof of principle, we quantified cetuximab-epidermal growth factor receptor binding kinetics using this system and assessed cetuximab RO in a tumor xenograft model. Incomplete ROs were observed, even at a supratherapeutic dose of 50 mg/kg, indicating that fractional target accessibility is achieved. The BRET-based imaging approach enables quantification of antibody in vivo RO and provides critical information required to optimize therapeutic mAb efficacy.

description: This letter deals with the opportunistic beamforming (OBF) scheme for multi-antenna downlink with spatial randomness. In contrast to conventional OBF, the terminals return only 1-bit feedback, which is powered by wireless power transfer through a rectenna array. We study two fundamental topologies for the combination of the rectenna elements; the direct-current combiner and the radio-frequency combiner. The beam outage probability is derived in closed form for both combination schemes, by using high order statistics and stochastic geometry.

description: In recent years, concerns over effective consumer representation of public transport users have increased considerably, as public transport has undergone substantial regulatory reforms. The ultimate goal of deregulation is to protect and benefit the public at large. Hence, this paper explores how this goal is being pursued by examining the roles of statutory, independent passenger watchdogs and their relationships with authorities and operators in regulated and deregulated bus regimes. Drawing on a case study of London TravelWatch and Transport Focus in Great Britain, our findings show that statutory passenger watchdogs are effective in representing passenger interests due to four factors in particular: the organizational setting, research-based evidence, accommodating relationships, and public outreach. The paper also documents the differences in how these passenger watchdogs build their relationships with key stakeholders and work with them within the strategic-tactical-operational framework.

Fueling China's Rise: Analyzing the Determinants of China's Foreign Energy Investments
Creators: name: Stelpflug, Will
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: I analyze the determinants of China’s foreign energy investments during the period 2001 to 2014. These investments include mergers and acquisitions and portfolio investments as well as loans. My analysis is done at the country level. I consider the effects of factors suggesting motives of market access (such as GDP and Chinese FDI), efficiency/cost reduction (such as GDP growth and per-capita GDP), access to energy resources (such as oil and natural gas reserves) and building political support (such as the presence of arms trade). I estimate the determinants of investment using a Tobit model with random effects, a two-stage Heckman Selection model, and Two-Stage Least-Squares (2SLS) simultaneous equations. I find that Chinese investors take into account considerations of securing access to energy resources, primarily oil, and building political support for China internationally, in tandem with their commercial motives to secure market access and reduce costs. For the largest investments, the motive to secure long-term control over oil supplies is especially strong.

This commentary on the editorial introduction by Rodrigo Magalhães and Hen- derik A. Proper focuses on the current design understanding in O D&E E, and judges it as too narrow in this context. The commentary shows how design as a concept needs to be broadened to contribute to this new emerging area of research and pactice in O D&E E.

Adherence and Compliance to a Community-Based Exercise Intervention and the Effect on VO2peak in Breast Cancer Survivors
Creators: name: Almond, Cassie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Purpose: As more breast cancer patients are surviving longer after diagnosis, there is a growing population of survivors dealing with long-term negative side effects of treatment. Exercise has been widely supported as an effective measure in mitigating these side effects. However, reporting of all exercise intervention components remains incomplete limiting our understanding of the effectiveness of specific exercise prescription components on primary outcomes and limits study replication. The purpose of this study was to evaluate the exercise adherence and compliance of breast cancer patients to a 16-week community-based, supervised, progressive, aerobic and resistance exercise training intervention and to determine the effects on change in VO2peak. Methods: Early stage breast cancer patients within one year of completing primary treatments were enrolled in a 16-week community-based exercise intervention. Participants attended 3, 1-hour small group exercise sessions per week. Over the course of the intervention, aerobic training increased intensities to 12-14 RPE, resistance training increased intensities to 14-15 RPE, and durations increasing to ~30min. Adherence reflects attendance: days attended vs. days prescribed. Compliance reflects the degree to which participants completed the exercise prescription; reaching prescribed intensities for prescribed durations. Results: Patients had an average aerobic and resistance adherence of 72.5%. Aerobic compliance of 23.6 days (49.1%) and resistance compliance of 12.5 days (26.0%). A paired samples t-test revealed a non-significant increase in VO2peak (+0.9 mL/kg/min, p=0.178) following the intervention. Conclusion: VO2peak improvements were not statistically significant. However, VO2peak was maintained following the intervention suggesting that with even low compliance maintenance of cardiorespiratory fitness is possible.

description: Arctic sea ice plays an important role in the global climate. Sea ice models governed by physical equations have been used to simulate the state of the ice including characteristics such as ice thickness, concentration, and motion. More recent models also attempt to capture features such as fractures or leads in the ice. These simulated features can be partially misaligned or misshapen when compared to observational data, whether due to numerical approximation or incomplete physics. In order to make realistic forecasts and improve understanding of the underlying processes, it is necessary to calibrate the numerical model to field data. Traditional calibration methods based on generalized least-square metrics are flawed for linear features such as sea ice cracks. We develop a statistical emulation and calibration framework that accounts for feature misalignment and misshapenness, which involves optimally aligning model output with observed features using cutting-edge image registration techniques. This work can also have application to other physical models which produce coherent structures. Supplementary materials accompanying this paper appear online.
Rhodes Must Fall and the Politics of Identity in Contemporary South Africa
Creators: name: Farrow, David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: My thesis seeks to examine the dissolution of Rhodes Must Fall through critically evaluating the role of identity and difference within the movement. I examine the theoretical debates surrounding intersectional identity formation and the relevancy of these debates to political action in South Africa. In particular, I will place intersectional understandings of identity in conversation with the critiques of identity offered by Stuart Hall. My thesis will first, in this chapter, outline the relevant elements of the South African context and then offer a timeline of Rhodes Must Fall. In Chapter 2, I will examine how intersectionality serves as both an organizing principle within the movement and as a strategy employed to advance the movement’s decolonial agenda.  In Chapter 3, I will argue that the means by which Rhodes Must Fall constructs intersectional identities relies on essentialist constructions of identity that hinder movement building and political efficacy. In Chapter 4, I will develop both a general critique of intersectionality drawing on Stuart Hall’s theorization of discourse, interpellation, representation, difference, and hybridity in relation to theories of identification, and a specific critique of intersectionality within the Rhodes Must Fall Movement. Finally, in Chapter 5, I will examine the governance strategies employed by the ruling African National Congress to contain dissent in order to further demonstrate the inadequacy of intersectional identity politics to radically alter status quo politics in South Africa.

description: Clinical research regularly includes required, nontherapeutic procedures to answer research questions. Optional procedures usually offer minimal or no personal benefit and may involve harms and burdens. Members from the Bangkok SEARCH010/RV254 HIV research cohort of individuals acutely HIV-infected are recruited to six optional procedures varying in invasiveness: leukapheresis, genital secretions collection, lumbar puncture, brain MRI/MRS/DTI, colon biopsy, and lymph node biopsy. We surveyed cohort members about their first recruitment for each procedure to examine factors associated with decision making and attitudes about compensation. 406 members (68%) completed the survey. Reported procedure participation ranged from 71% (MRI) to 27% (lymph node biopsy). Respondents underwent 0-6 procedure types (median 3). Ordinal regression indicated that lower perceived HIV impact and HIV remission trial participation were associated with more procedures completed. Reports of decision difficulty varied, and feeling pressured by research staff was low overall. Notably, those who declined procedures and those who underwent more invasive procedures reported greater decision difficulty and perceived pressure. Most respondents felt compensation amounts were appropriate, although opinions differed by procedure, and for some procedures, between people who agreed and declined. There is limited literature regarding consent to and attitudes about optional research procedures. Researchers must consider how to best support voluntary decisions for procedures with little personal benefit, particularly in lower-income or marginalized populations. In this longitudinal research cohort, perceived pressure to participate may be a concern, although our finding of variation in participation rates corresponding to invasiveness is reassuring. Data from different research contexts would provide important comparators.

description: The Fungal, Lichen, and Myxomycete Collections of the University of North Carolina (UNC) at Chapel Hill Herbarium (NCU) contain 952 type specimens, representing 607 names, which, based on current taxonomy and nomenclature, amount to 596 unique taxa. This wealth of type specimens is a legacy of the taxonomic research on fungi conducted by William C. Coker, Alma Holland Beers, John N. Couch, and other UNC mycologists in the first half of the 20th century. This inventory is a compilation of these types plus specimens for invalidly published designations that were intended as types by the mycologists who worked on these specimens. Also included are original material specimens intended as types for taxa in invalid publications, which were not included in the publications by subsequent authors validating the taxa. Fungal groups particularly well represented in the types held at NCU are boletes, clavarioid fungi, gasteroid fungi, hydnoid fungi, and septobasidia. A lectotype is designated for Clavaria atroumbrina. Since 2014, more than 1000 collections including >100 types have been loaned by NCU to mycologists at institutions around the world.
Ferret as a model system for studying the anatomy and function of the prefrontal cortex: A systematic review

description: There is a lack of consensus on anatomical nomenclature, standards of documentation, and functional equivalence of the frontal cortex between species. There remains a major gap between human prefrontal function and interpretation of findings in the mouse brain that appears to lack several key prefrontal areas involved in cognition and psychiatric illnesses. The ferret is an emerging model organism that has gained traction as an intermediate model species for the study of top-down cognitive control and other higher-order brain functions. However, this research has yet to benefit from synthesis. Here, we provide a summary of all published research pertaining to the frontal and/or prefrontal cortex of the ferret across research scales. The targeted location within the ferret brain is summarized visually for each experiment, and the anatomical terminology used at time of publishing is compared to what would be the appropriate term to use presently. By doing so, we hope to improve clarity in the interpretation of both previous and future publications on the comparative study of frontal cortex.
