description: The data underlying scientific papers should be accessible to researchers both now and in the future, but how best can we ensure that these data are available? Here we examine the effectiveness of four approaches to data archiving: no stated archiving policy, recommending (but not requiring) archiving, and two versions of mandating data deposition at acceptance. We control for differences between data types by trying to obtain data from papers that use a single, widespread population genetic analysis, STRUCTURE. At one extreme, we found that mandated data archiving policies that require the inclusion of a data availability statement in the manuscript improve the odds of finding the data online almost a thousand-fold compared to having no policy. However, archiving rates at journals with less stringent policies were only very slightly higher than those with no policy at all. At one extreme, we found that mandated data archiving policies that require the inclusion of a data availability statement in the manuscript improve the odds of finding the data online almost a thousand fold compared to having no policy. However, archiving rates at journals with less stringent policies were only very slightly higher than those with no policy at all. We also assessed the effectiveness of asking for data directly from authors and obtained over half of the requested datasets, albeit with about 8 days delay and some disagreement with authors. Given the long term benefits of data accessibility to the academic community, we believe that journal based mandatory data archiving policies and mandatory data availability statements should be more widely adopted.
Using multimodality to support culturally responsive learning and writing instruction in the college EAP classroom
Creators: name: Bilotta, Juliane
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation considers how English for Academic Purposes (EAP) instructors can reimagine notions of academic writing by exploiting multimodal texts in ways that invite students’ fuller language repertoires into the classroom. Using ethnographic data collected during the Spring 2022 semester of a college EAP class, this study argues that a multimodal approach to second language writing can help instructors reframe academic writing through a culturally responsive lens, supports students’ metalinguistic awareness, and offer students new ways of thinking about language and the writing process. Each article in this dissertation uses a different framework to consider the challenges and affordances of multimodality as well as the ways in which multimodality supports culturally responsive learning for students in higher education. The first article uses discourse analysis to demonstrate how engaging with multimodal texts enacted students’ deeper learning and critical thinking around the writing process. The second article uses third space theory (Gutiérrez, 2008) to demonstrate how students co-constructed meaning in ways that were contingent on their own experiences and knowledge. Finally, the third article looks at peer-review sessions and classroom interactions across the semester to show how students developed new ways of thinking about their own language and writing practices by engaging with multimodal frameworks. This work contributes to EAP research on multimodal learning, instruction, and culturally relevant pedagogy in higher education.
Dynamic coupling between a multistable defect pattern and flow in nematic liquid crystals confined in a porous medium

description: When a nematic liquid crystal is confined in a porous medium with strong anchoring conditions, topological defects, called disclinations, are stably formed with numerous possible configurations. Since the energy barriers between them are large enough, the system shows multistability. Our lattice Boltzmann simulations demonstrate dynamic couplings between the multistable defect pattern and the flow in a regular porous matrix. At sufficiently low flow speed, the topological defects are pinned at the quiescent positions. As the flow speed is increased, the defects show cyclic motions and nonlinear rheological properties, which depend on whether or not they are topologically constrained in the porous networks. In addition, we discovered that the defect pattern can be controlled by controlling the flow. Thus, the flow path is recorded in the porous channels owing to the multistability of the defect patterns.

Reliability estimators for the components of series and parallel systems: The Weibull model

Year: 2013

description: This paper presents a hierarchical Bayesian approach to the estimation of components' reliability (survival) using a Weibull model for each of them. The proposed method can be used to estimation with general survival censored data, because the estimation of a component's reliability in a series (parallel) system is equivalent to the estimation of its survival function with right- (left-) censored data. Besides the Weibull parametric model for reliability data, independent gamma distributions are considered at the first hierarchical level for the Weibull parameters and independent uniform distributions over the real line as priors for the parameters of the gammas. In order to evaluate the model, an example and a simulation study are discussed.

description: Applying magnetic fields up to B = 29 T, we investigate the formation of electric-field domains in Landau-quantized semiconductor superlattices. Surprisingly, the electric-field distribution remains determined by the subband spacing rather than by the cyclotron energy. At the domain boundary, however, strong inter-Landau-level tunneling occurs, which leads to a magnetically tunable number of extra resonances in the current-voltage curve. In addition, we discuss a novel magnetic-field assisted high-field domain also stabilized by inter-Landau-level tunneling.

description: Inelastic neutron scattering is used to measure the spin excitation spectrum of the Heisenberg $S=1/2$ ladder material (C$_7$H$_10$N)$_2$CuBr$_4$ in its entirety, both in the gapped spin-liquid and the magnetic field induced Tomonaga-Luttinger spin liquid regimes. A fundamental change of the spin dynamics is observed between these two regimes. DMRG calculations quantitatively reproduce and help understand the observed commensurate and incommensurate excitations. The results validate long-standing quantum field theoretical predictions, but also test the limits of that approach.
Managing Water Resources: Lessons from Florida and Georgia
Creators: name: Kundell, James E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1983

description: Water management is by and large a state responsibility. How a state has met this responsibility depends on a variety of factors such as the availability of water, demands placed on the water resource, types of water problems, state bureaucratic structure, and the political environment in which decisions are made. Each state has thus developed its own mechanisms for managing water resources. At the same time, however, common stimuli such as federal water quality mandates, federal funding for water projects, and new insights obtained from research have resulted in states addressing similar problems in similar ways.

description: We analyze the redshift- and luminosity-dependent sizes of dropout galaxy candidates in the redshift range z~7-12 using deep images from the UDF12 campaign, data which offers two distinct advantages over that used in earlier work. Firstly, we utilize the increased S/N ratio offered by the UDF12 imaging to provide improved size measurements for known galaxies at z=6.5-8 in the HUDF. Specifically, we stack the new deep F140W image with the existing F125W data in order to provide improved measurements of the half-light radii of z-dropouts. Similarly we stack this image with the new deep UDF12 F160W image to obtain new size measurements for a sample of Y-dropouts. Secondly, because the UDF12 data have allowed the construction of the first robust galaxy sample in the HUDF at z>8, we have been able to extend the measurement of average galaxy size out to significantly higher redshifts. Restricting our size measurements to sources which are now detected at >15sigma, we confirm earlier indications that the average half-light radii of z~7-12 galaxies are extremely small, 0.3-0.4 kpc, comparable to the sizes of giant molecular associations in local star-forming galaxies. We also confirm that there is a clear trend of decreasing half-light radius with increasing redshift, and provide the first evidence that this trend continues beyond z~8. Modeling the evolution of the average half-light radius as a power-law (1+z)^s, we obtain a best-fit index of s=-1.28+/-0.13 over the redshift range z~4-12, mid-way between the physically expected evolution for baryons embedded in dark halos of constant mass (s=-1) and constant velocity (s=-1.5). A clear size-luminosity relation, such as that found at lower redshift, is also evident in both our z- and Y-dropout sample. This relation can be interpreted in terms of a constant surface density of star formation over a range in luminosity of 0.05-1.0L*_z=3.(abridged)

Recovering Joys Law as a Function of Solar Cycle, Hemisphere, and Longitude

description: Bipolar active regions in both hemispheres tend to be tilted with respect to the East West equator of the Sun in accordance with Joys law that describes the average tilt angle as a function of latitude. Mt. Wilson observatory data from 1917 to 1985 are used to analyze the active-region tilt angle as a function of solar cycle, hemisphere, and longitude, in addition to the more common dependence on latitude. Our main results are as follows: i) We recommend a revision of Joys law toward a weaker dependence on latitude (slope of 0.13 to 0.26) and without forcing the tilt to zero at the Equator. ii) We determine that the hemispheric mean tilt value of active regions varies with each solar cycle, although the noise from a stochastic process dominates and does not allow for a determination of the slope of Joys law on an 11-year time scale. iii) The hemispheric difference in mean tilt angles, 1.1 degrees + 0.27, over Cycles 16 to 21 was significant to a three-sigma level, with average tilt angles in the northern and southern hemispheres of 4.7 degrees + 0.26 and 3.6 degrees + 0.27 respectively. iv) Area-weighted mean tilt angles normalized by latitude for Cycles 15 to 21 anticorrelate with cycle strength for the southern hemisphere and whole-Sun data, confirming previous results by Dasi-Espuig, Solanki, Krivova, et al. (2010, Astron. Astrophys. 518, A7). The northern hemispheric mean tilt angles do not show a dependence on cycle strength. vi) Mean tilt angles do not show a dependence on longitude for any hemisphere or cycle. In addition, the standard deviation of the mean tilt is 29 to 31 degrees for all cycles and hemispheres indicating that the scatter is due to the same consistent process even if the mean tilt angles vary.

description: The XCAT phantom is a realistic 4D digital torso phantom that is widely used in imaging and therapy research. However, lung mass is not conserved between respiratory phases of the phantom, making detailed dosimetric simulations and dose accumulation unphysical. A framework is developed to correct this issue by enforcing local mass conservation in the XCAT lung. Dose calculations are performed to assess the implications of neglecting mass conservation, and to demonstrate an application of the phantom to calculate the accumulated delivered dose in an irregularly breathing patient. Monte Carlo methods are used to simulate conventional and SBRT treatment delivery. The spatial distribution of the lung dose was qualitatively changed by the use of mass conservation; however the corresponding DVH did not change significantly. Comparison of the delivered dose with 4DCT-based predictions shows similar lung metric results, however dose differences of 10% can be seen in some spatial regions. Using this tool to simulate patient treatments reveals differences between the planned dose and the calculated delivered dose for the full treatment. The software is freely available from the authors.

Exploring Outdoor Recreation in Western North Carolina

description: Recreation and the great outdoors are a combination made in heaven and brought to Earth in western North Carolina (WNC). Estimates are that travel and tourism in the region will grow from the 1987 level of 8.0 percent of the region's total employment to 9.7 percent by 1995. Furthermore, the North Carolina Division of Travel and Tourism calculated that tourism spending in WNC was S862.6 million in 1991. With hundreds-of-thousands of acres of public and private recreational lands available, outdoor recreation is a significant component of this mountainous region's economy. A recent study conducted by the Mountain Outdoor Recreation Alliance (MORA) shows that, in general, outdoor recreationalists using private lands in western North Carolina seek conveniently located destinations of natural beauty that also maintain a sense of 'getting away from it all. Most outdoor recreationalists are visitors to the mountain region, either travelling together as a single family or as a group of unrelated friends, with the vast majority coming from states in the Southeast- North Carolina, Florida, South Carolina and Georgia. The most commonly identified factors which drew these visitors and keep them coming back are the scenic beauty and natural features in the region, the condition of recreational facilities and the helpfulness of employees. Given the importance of travel and tourism to the economy of WNC, it is essential to support outdoor recreation by maintaining the natural splendor of the region, preventing overuse and overcrowding of facilities, and improving travel to and within the region.
Narrating non-normative appetites: race, gender, and sexuality in the kitchen

description: This dissertation explores works of fiction and autobiography, from the mid-1900s to the present day, that portray the multifaceted eating disorders of marginalized populations through the lens of race, gender, and ecocritical theories, among others. I argue that oppressive patriarchal paradigms play an integral role in shaping how protagonists experience embodiment and understand self-identity. My analysis of these works reverses the terms of the psychoanalytic equation that attribute causes of eating disorders to interaction with the mother vis-à-vis food, showing instead how fathers, male partners, and in general the patriarchal structures of capitalism and war substantively influence the fluid nature of eating behavior and gender performance. While the European economic miracle of the 1960s simultaneously ushered in eating for entertainment as well as increasing rates of eating disorders, it was not until 1987 that the term “anorexia” was explicitly used in women’s autobiographies in Italy, soon after the floodgates to anorexographies had been flung open in the United States. Yet, in Western culture the phenomenon was confined to representations of White, affluent female characters, and only in the past decade has it expanded considerably to include other groups. Despite the upswing in literary output, research in the humanities, and to a large extent in the social sciences, still neglects non-traditional eating disorder narratives. My dissertation attempts to fill this void by taking a cross-cultural approach, examining the depiction of restrictive (e.g., veganism) and pathological eating behaviors (e.g., anorexia, bulimia, binge-eating, and rumination disorder) in relation to disabled bodies in Italian writings, in conversation with works belonging to other Western literatures.
The existence of a bending rigidity for a hard sphere liquid near a curved hard wall: Helfrich or Hadwiger?

description: In the context of Rosenfeld's Fundamental Measure Theory, we show that the bending rigidity is not equal to zero for a hard-sphere fluid in contact with a curved hard wall. The implication is that the Hadwiger Theorem does not hold in this case and the surface free energy is given by the Helfrich expansion instead. The value obtained for the bending rigidity is (1) an order of magnitude smaller than the bending constant associated with Gaussian curvature, (2) changes sign as a function of the fluid volume fraction, (3) is independent of the choice for the location of the hard wall.

description: Objectives: The objective of this study was to develop a value set for EQ-5D-5L based on the societal preferences of the German population. As the first country to do so, the study design used the improved EQ-5D-5L valuation protocol 2.0 developed by the EuroQol Group, including a feedback module as internal validation and a quality control process that was missing in the first wave of EQ-5D-5L valuation studies. Methods: A representative sample of the general German population (n = 1158) was interviewed using a composite time trade-off and a discrete choice experiment under close quality control. Econometric modeling was used to estimate values for all 3125 possible health states described by EQ-5D-5L. The value set was based on a hybrid model including all available information from the composite time trade-off and discrete choice experiment valuations without any exclusions due to data issues. Results: The final German value set was constructed from a combination of a conditional logit model for the discrete choice experiment data and a censored at −1 Tobit model for the composite time trade-off data, correcting for heteroskedasticity. The value set had logically consistent parameter estimates (p < 0.001 for all coefficients). The predicted EQ-5D-5L index values ranged from −0.661 to 1. Conclusions: This study provided values for the health states of the German version of EQ-5D-5L representing the preferences of the German population. The study successfully employed for the first time worldwide the improved protocol 2.0. The value set enables the use of the EQ-5D-5L instrument in economic evaluations and in clinical studies. © 2018 The Author(s)

Integrated genomic analyses of ovarian carcinoma

description: A catalogue of molecular aberrations that cause ovarian cancer is critical for developing and deploying therapies that will improve patients’ lives. The Cancer Genome Atlas project has analysed messenger RNA expression, microRNA expression, promoter methylation and DNA copy number in 489 high-grade serous ovarian adenocarcinomas and the DNA sequences of exons from coding genes in 316 of these tumours. Here we report that high-grade serous ovarian cancer is characterized by TP53 mutations in almost all tumours (96%); low prevalence but statistically recurrent somatic mutations in nine further genes including NF1, BRCA1, BRCA2, RB1 and CDK12; 113 significant focal DNA copy number aberrations; and promoter methylation events involving 168 genes. Analyses delineated four ovarian cancer transcriptional subtypes, three microRNA subtypes, four promoter methylation subtypes and a transcriptional signature associated with survival duration, and shed new light on the impact that tumours with BRCA1/2 (BRCA1 or BRCA2) and CCNE1 aberrations have on survival. Pathway analyses suggested that homologous recombination is defective in about half of the tumours analysed, and that NOTCH and FOXM1 signalling are involved in serous ovarian cancer pathophysiology.

description: High-resolution light distributions are lately in demand for vehicle headlamp systems as an innovative lighting approach. This lighting approach can realize functionalities, such as precise glare avoidance and on-road projection, which are useful for improving traffic comfort and safety. For achieving the required high-resolution light distribution, area-based projection technologies, such as DMD, LCD, and LCoS, are considered to be integrated into such headlamps. These projection devices demand rectangular illumination areas with specific light distributions to fulfill the requirements for illumination efficiency and performance in headlamp systems. Lenslet arrays, based on the principle of Kohler illumination, can effectively homogenize the light and shape it into rectangular shapes simultaneously. Such components are widely used in projection applications. However, they also show functional potentialities to be applied in high-resolution headlamps. This paper explains the design principles and methods of lenslet arrays for beam pre-shaping in headlamp systems. It validates the homogenization using a self-designed and manufactured lenslet array in a demonstrator in the first place. Afterward, this paper introduces two new methods for the centralized beam shaping required by some headlamps. These methods are validated by optical simulations.
If You Build It, Will They Come? Measuring Greenway Usage in Cary, N.C.
Creators: name: Bush, Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: A decade ago, the Town of Cary, N.C. implemented a greenway program but had no information available on the facilities’ usage. To address this shortcoming, the Town’s volunteer Greenway Committee initiated a program in 2007 to measure weekend greenway use. Study results showed that overall median usage for any segment on weekends is 11.35 users per hour. User counts were much higher on metro segments than on neighborhood segments. In addition, locating facilities alongside certain amenities, such as a lake or trailhead parking, may increase usage. Overall, walking was the most prevalent mode of travel. Temperature was found to have a definite impact on usage, with the highest usage occurring when temperatures were in the 60°Fs. There is little variation by time period or day; the notable exception is Sunday evening, when the median usage level increases to 15.28 users per hour. These results should provide a good guide for comparable suburban cities in similar climates regarding the potential weekend usage of their greenways.
Standards for Extending Extra-Territorial Jurisdiction: Written in Black and White?

Year: 2007

description: The following article examines the public outcry surrounding one town’s attempt to establish an extra-territorial jurisdiction (ETJ). Most towns easily establish ETJs with little or no resistance. In contrast, when the predominantly minority Town of Green Level attempted to use this common planning tool, it faced inordinately strong and negative public resistance. The author addresses each of the arguments made by members of the public against Green Level’s proposed ETJ, and finds that each argument is unfounded. In the end, she finds, the only difference between the Town of Green Level and its neighbors, who were allowed to extend ETJs, is that of racial composition.

description: Micro underwater vehicles (MUVs) have been highlighted recently for underwater explorations because of their high maneuverability, low price, great flexibility, etc. The thrusters of most conventional MUVs are driven by electromagnetic motors, which need big mechanical transmission parts and are prone to being interrupted by the variance of ambient electromagnetic fields. In this paper, a novel dual-rotor ultrasonic motor with double output shafts, compact size, and no electromagnetic interference is presented, characterized, and applied for actuating underwater robots. This motor was composed of a spindle-shaped stator, pre-pressure modulation unit, and dual rotors, which can output two simultaneous rotations to increase the propulsion force of the MUV. The pre-pressure modulation unit utilized a torsion spring to adjust the preload at the contact faces between the stator and rotor. The working principle of the ultrasonic motor was developed and the vibration mode of the stator was analyzed by the finite element method. Experimental results show that the no-load rotary speed and stalling torque of the prototype ultrasonic motor were 110 r/min and 3 mN m, respectively, with 150 V peak-to-peak driving voltage at resonance. One underwater robot model equipped with the proposed ultrasonic motor-powered thruster could move at 33 mm/s immersed in water. The dual-rotor ultrasonic motor proposed here provides another alternative for driving MUVs and is appropriate for developing specific MUVs when the electromagnetic interference issue needs to be considered. © 2019 by the authors.

description: We consider a hybrid scalar field which is non-minimally coupled to the matter and models a chameleon cosmology. By introducing an effective potential, we study the dependence of the effective potential's minimum and hybrid chameleon field's masses to the local matter density. In a dynamical system technique, we analyze the phase space of this two-field chameleon model, find its fixed points and study their stability. We show that the hybrid chameleon domination solution is a stable attractor and the universe in this setup experiences a phantom divide crossing.

description: In this contribution we provide benchmark problems in the field of computational solid mechanics. In detail, we address classical fields as elasticity, incompressibility, material interfaces, thin structures and plasticity at finite deformations. For this we describe explicit setups of the benchmarks and introduce the numerical schemes. For the computations the various participating groups use different (mixed) Galerkin finite element and isogeometric analysis formulations. Some programming codes are available open-source. The output is measured in terms of carefully designed quantities of interest that allow for a comparison of other models, discretizations, and implementations. Furthermore, computational robustness is shown in terms of mesh refinement studies. This paper presents benchmarks, which were developed within the Priority Programme of the German Research Foundation ‘SPP 1748 Reliable Simulation Techniques in Solid Mechanics—Development of Non-Standard Discretisation Methods, Mechanical and Mathematical Analysis’. © 2020, The Author(s).

description: For coating Brownian thermal noise reduction in future gravitational wave detectors, it is proposed to use light in the helical Laguerre-Gaussian LG3,3 mode instead of the currently used LG0,0 mode. However, the simultaneous reduction of quantum noise would then require the efficient generation of squeezed vacuum states in the LG3,3 mode. Current squeezed light generation techniques employ continuous-wave second harmonic generation (SHG). Here, we simulate the SHG for both modes numerically to derive first insights into the transferability of standard squeezed light generation techniques to the LG3,3 mode. In the first part of this paper, we therefore theoretically discuss SHG in the case of a single undepleted pump mode, which, in general, excites a superposition of harmonic modes. Based on the differential equation for the harmonic field, we derive individual phase matching conditions and hence conversion efficiencies for the excited harmonic modes. In the second part, we analyse the numerical simulations of the LG0,0 and LG3,3 SHG in a single-pass, double-pass and cavity-enhanced configuration under the influence of the focusing, the different pump intensity distributions and the individual phase matching conditions. Our results predict that the LG3,3 mode requires about 14 times the pump power of the LG0,0 mode to achieve the same SHG conversion efficiency in an ideal, realistic cavity design and mainly generates the harmonic LG6,6 mode. © 2020 Optical Society of America.

description: Abstract
                Background
                Pictorial cigarette pack warnings discourage smoking, but most evidence comes from studies of adults. Our qualitative study explored adolescents’ reactions to pictorial warnings on their parents’ cigarette packs.
                Methods
                We interviewed 24 adolescents whose parents received pictorial warnings on their cigarette packs as part of a randomized clinical trial. We conducted a thematic content analysis of the interview transcripts.
                Results
                Pictorial cigarette pack warnings led adolescents to imagine the depicted health effects happening to their parents, which elicited negative emotions. The warnings inspired adolescents to initiate conversations with their parents and others about quitting smoking. Adolescents believed the warnings would help smokers quit and prevent youth from starting smoking. Some current smokers said the warnings made them consider quitting.
                Conclusions
                Conversations about the pictorial warnings may amplify their effectiveness for smokers, their adolescent children, and friends of the adolescent children. Cigarette pack warnings may reach a broad audience that includes adolescent children of smokers.
Positioning Research Triangle Park for Continued Prosperity

description: Home to over 170 companies and 39,000 knowledge workers, the Research Triangle Park (RTP) is known globally as a center of ground-breaking innovation and discovery. But building a research cluster from scratch demanded careful collaboration and foresight from leaders in government, business, and academia. In the late 1950’s, with a state economy that relied heavily on agriculture, tobacco, furniture, and textiles, North Carolina leaders saw the pressing need for new opportunities in innovation industries. The key ingredients were already present in the Triangle: cheap land, research conducted at nationally recognized universities, and an educated labor pool. RTP thus became an early national example of a planned science park. The future of RTP requires this same careful collaboration and planning to ensure its continued success in a changing market.
