description: Ordinary differential equations (ODEs) and ordinary difference systems (O$Δ$Ss) invariant under the actions of the Lie groups $\mathrm{SL}_x(2)$, $\mathrm{SL}_y(2)$ and $\mathrm{SL}_x(2)\times\mathrm{SL}_y(2)$ of projective transformations of the independent variables $x$ and dependent variables $y$ are constructed. The ODEs are continuous limits of the O$Δ$Ss, or conversely, the O$Δ$Ss are invariant discretizations of the ODEs. The invariant O$Δ$Ss are used to calculate numerical solutions of the invariant ODEs of order up to five. The solutions of the invariant numerical schemes are compared to numerical solutions obtained by standard Runge-Kutta methods and to exact solutions, when available. The invariant method performs at least as well as standard ones and much better in the vicinity of singularities of solutions.

description: Understanding how Emirati students value Problem-Based Learning (PBL) in their learning of tertiary subjects such as Business and Information Technology (IT) is an essential component of the pedagogy adopted in UAE Higher Education to achieve active learning in those subject areas. This research targeted the ‘voice’ of Emirati students and their expatriate teachers in the use and subjective evaluation of PBL in their tertiary education experience. Their documented perceptions are available for future UAE education policy development. Currently, there is a lack of understanding of how effectively PBL is being implemented when teaching the subjects of Business and IT. This research took place at a UAE Higher College of Technology where PBL was being used as a part of internal assessments for Business and IT in the students’ first bachelor year of study. Data was collected from a purposive sample of 174 Emirati students and 8 teachers using Mixed Methods design - a questionnaire, student and teacher interviews and classroom observations of students participating in PBL group work were the tools used to establish student voice. The questionnaire results indicated that there is a strong consensus from the Emirati students (between 60 to 80%) and expatriate teachers (between 90 to 100%) in support of the PBL pedagogy being used as a form of assessment within their Business and IT classes. However, 40% of the student interviewees were not satisfied with PBL. The eight teachers were strongly satisfied with PBL as a form of assessment for their Business/IT students. The learning of Business/IT content and implementation of group work for projects were considered to engage students and motivate them although projects were considered a challenge in the PBL process. Students generally need better support as do the teachers in implementing new pedagogies which impact group dynamics, learning styles, resources and learning management. assist Emirati students who may be struggling with group dynamics, independent learning, and lack of teacher support and time management. Recommendations are made that for the sustainability of new pedagogies such as PBL, student and teacher voices be incorporated into curriculum decision making in UAE Higher Education taking account cultural and longitudinal implications for the whole education system.
Experimental Examination of the Effects of Fitspiration Images

Year: 2018

description: With the rise of photo-based media, women are exposed to increasingly unattainable bodytrends, including “fitspiration” (physically fit women to motivate exercise) and “thinspiration” (thin women to motivate weight loss). Although “fitspiration” is intended to encourage healthy exercise, its content is thematically similar to thin ideal stimuli, perhaps unintentionally triggering similar negative effects on body image. Using an experimental pre- and post- manipulation survey design, this study addresses the negative effects of viewing fitspiration images as well as factors that may moderate these effects. Study participants who viewed fitspiration photos reported significantly higher body dissatisfaction, lower positive affect, and lower self-esteem than study participants who viewed the control images. However, study participants who viewed viewed the thinspiration images had similar outcomes. Additionally, no condition created a significantly higher motivation to exercise or diet. Fitspiration images do not appear to lead to increased motivation to exercise, but seem to lead to similar outcomes as thinspiration images (e.g. decreased body satisfaction, lower affect, and reduced self-esteem) decreased body satisfaction, lower affect, and reduced self-esteem. We found some support that social comparison moderated positive affect and self-esteem with decreased positive affect and self-esteem in the fitspiration condition. Additional research should examine these results in a younger population are necessary.

description: Despite the vast research on decision making in critical incidents, little is known about the recording of decisions made in time constrained and dynamic policing environments. The coronial inquest into the Lindt Cafe siege prompted unprecedented levels of scrutiny into the key decisions made by police commanders in resolving uncertain and complex incidents. Decision capture was identified as an organisational deficiency that transcends most policing jurisdictions in applying an effective structure or approach to enable officers to accurately record their decisions and supporting rationale in high tempo operating environments. This study examines tactical level commanders in an Australian policing jurisdiction to understand the current approaches to decision capture and the influences that impact on the timely and accurate recording of decision information. Drawing on semi-structured interview data from nine police officers, the findings identified a shift from handwritten artefacts towards technological solutions such as body worn cameras and police radio networks to record their decisions. This analysis determined that there was no organisational structure to this recording process and decision information was limited and unlikely to withstand scrutiny if critically reviewed. Based on these findings, the study proposes a concept of a three-tiered decision support mechanism that may assist to provide capacity to improve organisation effectiveness in responsive decision capture.
Raptor Codes in the Low SNR Regime

description: In this paper, we revisit the design of Raptor codes for binary input additive white Gaussian noise (BIAWGN) channels, where we are interested in very low signal to noise ratios (SNRs). A linear programming degree distribution optimization problem is defined for Raptor codes in the low SNR regime through several approximations. We also provide an exact expression for the polynomial representation of the degree distribution with infinite maximum degree in the low SNR regime, which enables us to calculate the exact value of the fractions of output nodes of small degrees. A more practical degree distribution design is also proposed for Raptor codes in the low SNR regime, where we include the rate efficiency and the decoding complexity in the optimization problem, and an upper bound on the maximum rate efficiency is derived for given design parameters. Simulation results show that the Raptor code with the designed degree distributions can approach rate efficiencies larger than 0.95 in the low SNR regime.

description: Historically, Black Caribbean children have faced disadvantage in education. From the 1970s Black Caribbean pupils received fewer O levels than white pupils and were over-represented among those classed as educationally subnormal. In the last decade, a continued trend of Black Caribbean boys over-represented in permanent exclusions in comparison to their white counterparts. Research also shows that Black Caribbean boys are disproportionally identified with SEMH in secondary schools. This research aimed to provide Black Caribbean boys with a unique opportunity to share their lived experience of secondary school within the UK. A collaborative element was used. 4 Black Caribbean boys formed a focus group to construct the interview questions. The study adopted a qualitative design with semi-structured interviews. Four boys between 14 and 15 years of age were interviewed. The researcher adopted an interpretivist epistemological stance and used Interpretative Phenomenological Analysis to interpret the data. Seven superordinate themes were identified across the participants: ‘Positive influence of peers’, ‘The perceived negative perceptions of black people’, ‘Dealing with the perception of teachers’, ‘Effective support from teachers’, ‘The impact of school policy and initiatives’ ‘The influence of family’ and ‘The impact of teachers of the same ethnicity’. The researcher identified from the findings experiences which fostered the resilience of the participants. Collaborating with the students ensured that their voices are foregrounded in the research. Implications for Educational Psychologists and school professionals are suggested, along with suggestions for further research.
Combined Spatial Analysis of Climate Change and Ethnic Conflict in Africa
Creators: name: Irby, Paul

Year: 2017

description: Climate change is anticipated by many to impact nearly every aspect of society in some way in the coming century. A potential to jeopardize security, especially in underdeveloped countries, is a claim commonly accepted by intelligence and security organizations but hotly debated in a growing body of scholarly literature. This study builds upon spatial methodology used in previous studies, and attempts to bridge outcomes to environmental and social context in a sample of 10 countries across Sub-Saharan Africa. The relationship between temperature change, precipitation variation from normal, ethnopolitical marginalization, and the existence of conflict was analyzed using disaggregated spatial and statistical methods, under the hypothesis that climate variation will correlate positively with conflict especially when it occurs in areas with marginalized people. The study finds some support for this hypothesis, indicating positive relationships with varying predictive strength among temperature and marginalization, but statistically insignificant results for precipitation. Logistic regression gave coefficients of 0.11 for temperature change (°C), and 0.31 for marginalization when conducted on the entire sample. The study finds that the impact of all independent variables varies dramatically based on geography, and more useful results are returned by dividing the area into geographically and climatically similar groupings. These results moderately support claims that climate change will increase conflicts due to temperature but not for precipitation, but stress the importance of localized analysis and the peril of oversimplification.

Examining the geologic link of arsenic contamination in groundwater in Orange County, NC
Creators: name: Dinwiddie, Ethan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: In recent decades, elevated arsenic concentrations in groundwater have been observed at various locations around the world including the Carolina terrane North Carolina. Orange County lies in the middle of the Carolina terrane and previous studies have observed arsenic concentrations in private well water samples that exceed the EPA drinking water standard of 10 ppb. This study uses a large database of arsenic concentrations and other water quality measurements in private water wells collected by the North Carolina Department of Health and Human Services and whole rock arsenic analysis to examine a possible geologic connection to elevated arsenic concentrations in groundwater. Through the use of geostatistical modeling and multivariate statistics, a hydrogeologic connection between certain water quality variables and detectable arsenic is found.

description: The causal structure of a stochastic process can be more efficiently transmitted via a quantum channel than a classical one, an advantage that increases with codeword length. While previously difficult to compute, we express the quantum advantage in closed form using spectral decomposition, leading to direct computation of the quantum communication cost at all encoding lengths, including infinite. This makes clear how finite-codeword compression is controlled by the classical process' cryptic order and allows us to analyze structure within the length-asymptotic regime of infinite-cryptic order (and infinite Markov order) processes.

Parental Racial Socialization and Adolescents' Self-Esteem: Influences on Academic Achievement
Creators: name: Duckett, Alexis
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The purpose of this study was to examine two types of racial socialization messages (preparation for bias and racial pride), self-esteem, and academic achievement of African American adolescents. Parents reported their racial socialization practices with their children and children’s academic achievement and self-esteem were assessed in 287 African American 10th graders. Contrary to study hypotheses, racial socialization practices were not significantly related to academic achievement. Nonetheless, the study results supported the hypothesized positive relationship between self-esteem and academic achievement. The results suggest a need for interventions aimed at increasing self-esteem in African American adolescents.

description: In biological systems, chemical signals termed morphogens self-organize into patterns that are vital for many physiological processes. As observed by Turing in 1952, these patterns are in a state of continual development, and are usually transitioning from one pattern into another. How do cells robustly decode these spatio-temporal patterns into signals in the presence of confounding effects caused by unpredictable or heterogeneous environments? Here, we answer this question by developing a general theory of pattern formation in spatio-temporal variations of ‘pre-pattern’ morphogens, which determine gene-regulatory network parameters. Through mathematical analysis, we identify universal dynamical regimes that apply to wide classes of biological systems. We apply our theory to two paradigmatic pattern-forming systems, and predict that they are robust with respect to non-physiological morphogen variations. More broadly, our theoretical framework provides a general approach to classify the emergent dynamics of pattern-forming systems based on how the bifurcations in their governing equations are traversed.
Welfare Effects of Ticket Resale: A Game Theoretic Analysis
Creators: name: Lin, Yebei
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The concert ticket business consists of two players: the primary ticket seller
and the scalpers. Ticketmaster is the dominant primary ticket seller. It has attempted
several projects in hopes of breaking into the secondary ticket market. In this paper,
we first investigate its merger with Live Nation, a concert promoting business.
Members of U.S. Congress and several consumer protection groups opposed the
merger due to the combined company’s control of ticket sales and concert venues;
however, the merger was approved by the U.S. Department of Justice in January
2010.
The increasing presence of online ticketing has equipped scalpers with new
technology. Regular consumers have to compete with “ticket bots,” which are virtual
robots that are programmed to buy up tickets to be sold at a higher price. The
secondary ticket market is currently a $4 billion-a-year business. The research in
this project examines the change in total welfare when scalpers are introduced. We
created our own model of the ticket market incorporating a monopolist, scalpers,
and regular consumers. We took into account the externality effect of concert attendance
in calculating monopolist’s revenue. Our results suggest that in some
scenarios the inclusion of scalpers does not change the total welfare. In order to
protect consumer’s interest, legal restrictions limiting ticket resale may not be as
effective as introducing competition in the primary ticket market.

description: Customer adoption of new solutions is critical for the development of the modern business environment, and both academics and practitioners have been investigating this notion to uncover the customer adoption patterns to progress business and withstand competition. Despite the variety of marketing research techniques and practices commonly used to obtain customer data it has been said that the customers that “talk the talk” do not always “walk the walk” of innovation adoption. The challenge remains unchanged: making innovation accessible and easy to adopt in consumers’ everyday lives. This thesis is looking into the processes of creating new solutions to identify the key drivers within the ideation processes that facilitate adoption. The research inquiry is supported by the tendencies in the industry, where, despite the increasing number of new technologies and approaches aimed to develop better products, the success-to-failure ratios remain quite low. The aim of the study is to design an integrative theoretical framework, explaining the drivers of ideation, the impact of customer orientation within ideation, and the influence it has on innovation adoption. The author used integrated methodology, combining the best practices of the deductive approach, commonly applied in conceptual works, and qualitative research methodology, where further insights were uncovered via interviews and a focus group. In this research project, the integrated methodology has been applied to combine the strengths of each of the research techniques and uncover insights into the complex notions and relationships under investigation. The findings include the introduction of COI and the three-dimensional model, facilitating the solutions development practice, aiming to help achieve a more sustainable growth within the service industries. The author has introduced a novel notion of Customer Oriented Ideation (COI) that focuses on the use of customer insights within the solutions development process and its impact on the market success. The author has also developed a questionnaire for further quantitative investigation of the framework, and further refined it via a pilot study.

description: We calculate the one-point probability density distribution functions (PDF) and the power spectra of the thermal and kinetic Sunyaev-Zeldovich (tSZ and kSZ) effects and the mean Compton Y parameter using the Magneticum Pathfinder simulations, state-of-the-art cosmological hydrodynamical simulations of a large cosmological volume of (896 Mpc/h)^3. These simulations follow in detail the thermal and chemical evolution of the intracluster medium as well as the evolution of super-massive black holes and their associated feedback processes. We construct full-sky maps of tSZ and kSZ from the light-cones out to z=0.17, and one realization of 8.8x8.8 degree wide, deep light-cone out to z=5.2. The local universe at z<0.027 is simulated by a constrained realisation. The tail of the one-point PDF of tSZ from the deep light-cone follows a power-law shape with an index of -3.2. Once convolved with the effective beam of Planck, it agrees with the PDF measured by Planck. The predicted tSZ power spectrum agrees with that of the Planck data at all multipoles up to l~1000, once the calculations are scaled to the Planck 2015 cosmological parameters with Ω_m=0.308 and σ_8=0.8149. Consistent with the results in the literature, however, we continue to find the tSZ power spectrum at l=3000 that is significantly larger than that estimated from the high-resolution ground-based data. The simulation predicts the mean fluctuating Compton Y value of =1.18x10^{-6} for Ω_m=0.272 and σ_8=0.809. Nearly half (~ 5x10^{-7}) of the signal comes from halos below a virial mass of 10^{13}M_\odot/h. Scaling this to the Planck 2015 parameters, we find =1.57x10^{-6}. The PDF and the power spectrum of kSZ from our simulation agree broadly with the previous work.

description: The current study was conducted to investigate factors that would motivate African American adolescents to engage in learning mathematics, as academic engagement is related to math achievement. Participants were African American students (N = 159) from the southeastern region of the United States who participated in a longitudinal study of academic achievement and identity development. The study used data collected from the participants in Grade 10 and Grade 12. Bivariate correlations and linear regression analyses were calculated to examine student reports of competence, autonomy, relatedness and math self-concept as predictors of math teachers’ reports of students’ classroom engagement. Math teachers reported students’ classroom engagement at each time point. Bivariate correlations showed that students’ perceptions of competence and autonomy in Grade 10 were related to their Grade 10 math engagement. Relatedness in Grade 10 was not related to students’ Grade 10 math engagement. Grade 10 measures were not related to Grade 12 math engagement. Linear regression analyses showed that Grade 10 perceptions of competence was a positive predictor of math Grade 10 math engagement.

description: We explore the effect of galactic environment on properties of molecular clouds. Using clouds formed in a large-scale galactic disc simulation, we measure the observable properties from synthetic column density maps. We confirm that a significant fraction of unbound clouds forms naturally in a galactic disc environment and that a mixed population of bound and unbound clouds can match observed scaling relations and distributions for extragalactic molecular clouds. By dividing the clouds into inner and outer disc populations, we compare their distributions of properties and test whether there are statistically significant differences between them. We find that clouds in the outer disc have lower masses, sizes, and velocity dispersions as compared to those in the inner disc for reasonable choices of the inner/outer boundary. We attribute the differences to the strong impact of galactic shear on the disc stability at large galactocentric radii. In particular, our Toomre analysis of the disc shows a narrowing envelope of unstable masses as a function of radius, resulting in the formation of smaller, lower mass fragments in the outer disc. We also show that the star formation rate is affected by the environment of the parent cloud, and is particularly influenced by the underlying surface density profile of the gas throughout the disc. Our work highlights the strengths of using galaxy-scale simulations to understand the formation and evolution of cloud properties - and the star formation within them - in the context of their environment.

Count or Context: Investigating Methods of Text Analysis
Creators: name: Neal, Anissa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Using text as a source of psychological and cognitive information has become a popular
subject (Robinson, Navea & Ickes, 2013; Donahue, Liang & Druckman, 2014; Wolfe &
Goldman, 2003). To do this, researchers use a variety of methods to analyze text, but Linguistic
Inquiry Word Count (LIWC) has become one the more common techniques. LIWC is a tokenbased
method that contains multiple dictionaries representing various psychological states
(positive affect, leisure, religion, social words) and keeps a running tabulation of how many
words in a given text occur in each category. Latent Semantic Analysis (LSA) is a context-based
method that uses statistics to calculate similarity between different texts based off the
surrounding words. As a common strategy of analyzing text for psychological states, it is
important LIWC be truly representative of the aspects it explores. The dictionaries must
accurately represent the categories they measure to be an authentic assessment of the analyzed
psychological and cognitive states.
This current study seeks to use LSA to improve LIWC. The hypothesis is that a
combination method of the two will perform better than the application of a single token-based
method. LIWC and two other token-based methods were compared to a combination LSA-token
method. The two techniques were applied to a set of headlines that had been previously judged
by humans in terms of emotion and positive/negative valence. The first part of the experiment
compared the token-based methods to confirm that they were different from each other but still
successful measures of the stimuli. The second part of the experiment compared the correlation
between the token-based method and the correct response of the pre-tagged data against the
correlation of the combination method and the pre-tagged stimuli. The findings did not support
the hypothesis, as the combination method performed worse than the token-based methods.
These results, however, suggest further investigation into the power of LSA and its reliance on
context. Specifically, LSA may be suited for analysis of longer, more semantically complex
texts, not short, basic samples, like the headlines used in this study.

description: The two-loop renormalization group flow is studied via the induced bracket flow on 3D unimodular Lie groups. A number of steady solitons are found. Some of these steady solitons come from maximally symmetric metrics that are steady, shrinking, or expanding solitons under Ricci flow, while others are not obviously related to Ricci flow solitons.

description: Long-acting injectables are a unique drug formulation strategy, providing a slow and sustained release of active pharmaceutical ingredients (APIs). In this study, a novel approach that combines liquid antisolvent precipitation with seeding to obtain a stable form of the API indomethacin while achieving the desired particle size distribution is described. It was proven that when a metastable form of indomethacin was initially nucleated, the rate of its transformation to the stable form was influenced by the presence of excipients and seeds (17.10 ± 0.20 μm), decreasing from 48 to 4 h. The final particle size (D50) of the indomethacin suspension produced without seeding was 7.33 ± 0.38 μm, and with seeding, it was 5.61 ± 0.14 μm. Additionally, it was shown that the particle size distribution of the seeds and the time point of seed addition were critical to obtain the desired solid-state form and that excipients played a crucial role during nucleation and polymorphic transformation. This alternative, energy-efficient bottom-up method for the production of drug suspensions with a reduced risk of contamination from milling equipment and fewer processing steps may prove to be comparable in terms of stability and particle size distribution to current industrially accepted top-down approaches.

Uncanny Domesticity: Interrogating Gender and the Fantastic in Marie NDiaye
Creators: name: Balkoski, Leah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Gender stands as an example of the uncanny in Marie NDiaye’s novels as a familiar and purportedly natural category from which her characters gradually realize their true foreignness. In her work, NDiaye represents individual women’s internal psychological struggles and external material struggles with gender through the creation of realistic fictional worlds that are subtly but inescapably unsettling. By warping familiar landscapes with fantastic and uncanny elements, NDiaye recreates the feeling of dis-ease that defines women’s experience in a society that so strictly enforces gender both socially and psychologically. This thesis specifically explores NDiaye’s presentation of women’s ambivalence toward femininity with the fantastic archetypes of the ghost, witch, and hero(ine)/flâneur (flâneuse) in Autoportrait en vert (2009), La Sorcière (1996), and En Famille (1991), and engages with Freud’s theory of the uncanny as well as Derrida’s concept of hauntology and feminist/post-feminist theory.

description: A major goal of neuroscience, statistical physics and nonlinear dynamics is to understand how brain function arises from the collective dynamics of networks of spiking neurons. This challenge has been chiefly addressed through large-scale numerical simulations. Alternatively, researchers have formulated mean-field theories to gain insight into macroscopic states of large neuronal networks in terms of the collective firing activity of the neurons, or the firing rate. However, these theories have not succeeded in establishing an exact correspondence between the firing rate of the network and the underlying microscopic state of the spiking neurons. This has largely constrained the range of applicability of such macroscopic descriptions, particularly when trying to describe neuronal synchronization. Here we provide the derivation of a set of exact macroscopic equations for a network of spiking neurons. Our results reveal that the spike generation mechanism of individual neurons introduces an effective coupling between two biophysically relevant macroscopic quantities, the firing rate and the mean membrane potential, which together govern the evolution of the neuronal network. The resulting equations exactly describe all possible macroscopic dynamical states of the network, including states of synchronous spiking activity. Finally we show that the firing rate description is related, via a conformal map, with a low-dimensional description in terms of the Kuramoto order parameter, called Ott-Antonsen theory. We anticipate our results will be an important tool in investigating how large networks of spiking neurons self-organize in time to process and encode information in the brain.

NUMERICAL ANALYSIS ON THE BEHAVIOR OF PRESTRESSED CONCRETE SLEEPER UNDER DIFFERENT SUPPORT CONDITIONS
Creators: name: Haftom G/Michael
Publisher: name: Zenodo
Year: 2016

description: Railway sleepers have important roles in the complex railway system. Throughout the international railway community, many methods have been developed to design and analyze the concrete sleepers. Specifically, this paper focuses on how changes in support condition affect the internal behavior of the sleeper. Due to different loading condition, poor maintenance or bad quality of ballast, a random load distribution along the sleeper-ballast interface may occur. A sleeper design, and also the track system design, which do not consider the random load distribution, could influence the performance of the sleeper and even damage the whole railway system. Thus, a numerical analysis for a pre-stressed concrete mono-block railway sleeper is carried out using finite element method. The internal behavior of a single sleeper subjected to a varying sleeper-ballast interaction is studied and, a linear-elastic sleeper analysis model was developed. This model was used to perform a study to determine the sensitivity of the sleeper to changes in ballast reaction along the sleeper. Four different possible scenarios of support conditions for a sleeper with varying contact length are discussed in numerical analysis. Results of vertical displacement and flexural stress of both rail seat and at mid-section of sleeper are presented.

description: We use one single, few-picosecond-long, variably polarized laser pulse to deterministically write any selected spin state of a quantum dot confined dark exciton whose life and coherence time are six and five orders of magnitude longer than the laser pulse duration, respectively. The pulse is tuned to an absorption resonance of an excited dark exciton state, which acquires non-negligible oscillator strength due to residual mixing with bright exciton states. We obtain a high fidelity one-to-one mapping from any point on the Poincaré sphere of the pulse polarization to a corresponding point on the Bloch sphere of the spin of the deterministically photogenerated dark exciton.
