At the Frontiers of Writing: Exploring the Productive Encounter between the Poetic and the Political in Northern Ireland during The Troubles
Creators: name: Bufkin, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: This thesis aims to explore the nature of that productive relationship: between the poet and the revolutionary, the poem and the political imaginary. To do so, I want to critically examine the ligature between three points—the poet as a social position within Northern Ireland during the 1960s and 70s; the poetic as a culturally-constructed and defined category of the aesthetic operating within the Northern Irish 20th Century context; and poesis as the individual and creative work that the poem enacts through the materiality of its language.

description: In this panel, archivists specializing in time-based born-digital workflows will discuss their use cases involving the span of collections processing practices, from “best” to the practical reality of “good enough”. These use cases will highlight situations wherein video quality, subject matter, file size and stakeholder expectations play decisive roles impacting preservation workflows. From these experiences, the panel will put forth suggestions for tiered preservation decision making, recognizing that not all files should necessarily be treated alike. The goal of this presentation is to discuss real-world workflows, taking into account institutional culture, policy, digital storage, staffing, and tools. The panel emphasizes the ‘art’ in the science of digital video preservation by exploring alternatives to the idea of one-size-fits-all ‘best practice’ recommendations. The panelists will engage with each other throughout to discuss how their different approaches towards digital video preservation have been impacted by the needs and capabilities of their institution, and how one organization’s best practice might be inappropriate or impractical for another. The goal of the panelists is to demystify the process of preserving born-digital video, and explore the role that creativity can play in developing policies and workflows that are ‘good enough’.

Similarly, for the reuse of digital preserved content, each time a story is retold it a new context, the story accumulates new meaning. SCIENCE IN ART: Recent, current, and future technologies enable creators to engage in new and evolving forms of interactive and cumulative storytelling that present preservation challenges. How do we document storytelling in digital form? ART IN SCIENCE: Storytelling may itself be/become a preservation strategy to accumulate and share complex context for complex digital content. How do we convey to the future the content, context, and significance of storytelling and other complex digital content forms? This moderated discussion panel will include brief explanatory and illustrative presentations and explore storytelling opportunities and challenges for creators and curators.

description: As the thinnest conductive and elastic material, graphene is expected to play a crucial role in post-Moore era. Besides applications on electronic devices, graphene has shown great potential for nano-electromechanical systems. While interlayer interactions play a key role in modifying the electronic structures of layered materials, no attention has been given to their impact on electromechanical properties. Here we report the positive piezoconductive effect observed in suspended bi- and multi-layer graphene. The effect is highly layer number dependent and shows the most pronounced response for tri-layer graphene. The effect, and its dependence on the layer number, can be understood as resulting from the strain-induced competition between interlayer coupling and intralayer transport, as confirmed by the numerical calculations based on the non-equilibrium Green's function method. Our results enrich the understanding of graphene and point to layer number as a powerful tool for tuning the electromechanical properties of graphene for future applications.

Speech Registers and Class Awareness in Terence's Meretrices
Creators: name: Mazzara, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: My decision to limit this analysis of the speech of New Comedy meretrices to the plays of Terence is based upon a distinction between the meretrices of Plautus and those of Terence. The two playwrights’ treatments of this stock character type differ by giving the meretrices different roles to play in resolving the citizen-based plots of their plays. While Plautine meretrices typically pursue their own interests more attentively than those of citizen families, thus adhering to stereotypes about the meretrix stock type, Terentian meretrices promote the success of citizen families or individual family members whenever the plot places citizens in precarious positions. Plautus and Terence have different degrees of interest in citizens: Plautus foregrounds the non-citizen characters such as slaves, while Terence devotes more time to citizen families. The distinction between meretrices who are interested and uninterested in citizen families corresponds to the differing degrees of interest that Terence and Plautus take in the citizen-based plots of their plays.

Dirac Quantum Cellular Automaton from Split-step Quantum Walk

description: Simulations of one quantum system by an other has an implication in realization of quantum machine that can imitate any quantum system and solve problems that are not accessible to classical computers. One of the approach to engineer quantum simulations is to discretize the space-time degree of freedom in quantum dynamics and define the quantum cellular automata (QCA), a local unitary update rule on a lattice. Different models of QCA are constructed using set of conditions which are not unique and are not always in implementable configuration on any other system. Dirac Cellular Automata (DCA) is one such model constructed for Dirac Hamiltonian (DH) in free quantum field theory. Here, starting from a split-step discrete-time quantum walk (QW) which is uniquely defined for experimental implementation, we recover the DCA along with all the fine oscillations in position space and bridge the missing connection between DH-DCA-QW. We will present the contribution of the parameters resulting in the fine oscillations on the Zitterbewegung frequency and entanglement. The tuneability of the evolution parameters demonstrated in experimental implementation of QW will establish it as an efficient tool to design quantum simulator and approach quantum field theory from principles of quantum information theory.

description: Cosmic voids are the largest and most underdense structures in the Universe. Their properties have been shown to encode precious information about the laws and constituents of the Universe. We show that machine learning techniques can unlock the information in void features for cosmological parameter inference. We rely on thousands of void catalogs from the GIGANTES dataset, where every catalog contains an average of 11,000 voids from a volume of $1~(h^{-1}{\rm Gpc})^3$. We focus on three properties of cosmic voids: ellipticity, density contrast, and radius. We train 1) fully connected neural networks on histograms from individual void properties and 2) deep sets from void catalogs, to perform likelihood-free inference on the value of cosmological parameters. We find that our best models are able to constrain the value of $Ω_{\rm m}$, $σ_8$, and $n_s$ with mean relative errors of $10\%$, $4\%$, and $3\%$, respectively, without using any spatial information from the void catalogs. Our results provide an illustration for the use of machine learning to constrain cosmology with voids.

description: Rectangular nanowires may have domain walls nucleated and moved through them to realize many devices. It has been shown that at a particular width and thickness of a nanowire with perpendicular anisotropy, there is a switch from the domain wall being of Bloch-type to it being of Néel-type. This critical shape can be found through micromagnetics simulations, but here we present an analytic calculation for the energies of both wall types involving two iterations for the demagnetizing energy density. The expressions developed are long, but have the advantage that by simply inputting material parameters for the magnetic material, the critical shape can be found using a calculator in a matter of seconds. We compare our results to those found using micromagnetics and those found experimentally and the agreement is good.

On Digital Dualism: An Exploration of Internet Privacy, Media Representation, and Online Identity
Creators: name: Bass, Shelby
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Motivating Ideas: The primary goal of the work I have created over the course of my honors thesis is to explore the fallacy of “digital dualism.” Digital dualism, a phrase coined by researcher and social media theorist Nathan Jurgenson, is the idea that the “digital world is ‘virtual’ while the physical world is ‘real’ (“Digital Dualism versus Augmented Reality” 1). I would argue instead that “digital and material realities…coconstruct each other” (“Towards Theorizing an Augmented Reality” 2). The digital and physical worlds in the 21st century are inextricably linked – what goes on online can have profound “real-world” implications, and vice-versa. The two implications that I have focused on in my work this semester are digital privacy and the portrayal of underrepresented groups in media. My work #3B5998 seeks to visually represent the real
world, human impact of online privacy violation and explores issues of manipulation and color psychology as it relates to the social network site Facebook. Selfierepresentation explores identity in the digital age and challenges how underrepresented groups are often portrayed in mass media; this piece also explores the political possibilities of online self-representation and deals with politics, agency, and the evolving language of the internet.

description: This work investigates the migration of spherical particles of different sizes in a centrifuge-driven deterministic lateral displacement (c-DLD) device. Specifically, we use a scaled-up model to study the motion of suspended particles through a square array of cylindrical posts under the action of centrifugation. Experiments show that separation of particles by size is possible depending on the orientation of the driving acceleration with respect to the array of posts (forcing angle). We focus on the fractionation of binary suspensions and measure the separation resolution at the outlet of the device for different forcing angles. We found excellent resolution at intermediate forcing angles, when large particles are locked to move at small migration angles but smaller particles follow the forcing angle more closely. Finally, we show that reducing the initial concentration (number) of particles, approaching the dilute limit of single particles, leads to increased resolution in the separation.

description: How are we archiving and providing access to non-traditional art and design theses work? Through the National Digital Stewardship Residency Art program, the Maryland Institute College of Art is looking to develop and share a new model for the acquisition, preservation, and access to art and design theses by collaborating with students and faculty. Preservation of art and design theses presents particular issues as flattened images and video stills embedded in PDFs are not an accurate representation of works of art. As new and complex media is integrated into art and design work, we will need to provide better access to media to showcase student work in a way that’s authentic, accessible and discoverable. As per the current workflow, digital media such as high resolution images, moving images, and interactive and 3D media are submitted to the institutional repository as supplemental materials. But are “supplemental materials” really supplemental? Or are we really putting away the essence of student artwork on USBs and CDs while displaying textual explanations of visual art? This session hopes to illustrate how art is the essence of theses work and expound on the importance of supporting the integration of technology into artwork and the development of a process that allows for true engagement with this material. The session will focus on the themes of collaboration and responsibility, awareness of post-production digital archival work, and the possible impact of implementing new digital preservation strategies of theses work as students and faculty start to see the potential ways in which their work may become openly accessible online.

description: Excerpts from the report: World agricultural trade has increased appreciably since the disruption of World War II, and its contribution to the post-war recovery of Europe was substantial. Although all countries import or export some agricultural products, trade is generally dominated by the industrialized countries of North America and Europe. For example, the United States is the world's largest exporter and second largest importer of agricultural products. Excluding the United States, 6 of the 7 major importers are in Western Europe -- the United Kingdom, West Germany, France, Italy, the Netherlands, and Belgium-Luxembourg. The rapidly expanding Japanese market resulted in that country moving up to the third largest importer of the seven. In 1965, these 7 countries imported agricultural products valued at $20,599 million. In 1964, the last year comparable data were available, agricultural imports by the 7 major importers accounted for 61 percent of total farm product imports by 79 countries. With U.S. imports added to those of the 7 practically 75 percent of world agricultural imports are made by 8 countries. This report on agricultural imports in 1960-65 by the seven largest importers, excluding the United States, includes analysis of total and commodity trade on imports from the United States, from other developed countries, from Eastern Trade Area, and from the less developed countries.

Perceptions of Attractiveness, Discrimination, and Racial Bias
Creators: name: Hossfeld, Cassius Modisana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: How might one’s attractiveness shape the discrimination they receive, and how might this relationship be affected by racial bias? The purpose of this study is to explore the relationship between perceived attractiveness and perceptions of discrimination, and how this relationship is the same or different for whites and blacks. In this research, I examine the link between these variables, and try to uncover a possible relationship that might exist. To do this, I used survey data from the Add Health dataset, from the Carolina Population Center, by coding response questions into cumulative index variables and interpreting the results. The results suggest that there is indeed a negative relationship between attractiveness and discrimination. Furthermore, the results indicate racial bias might exist by muting the strength of this relationship for black respondents, as no association between the variables exists when measuring this group.
Accelerated and Airy-Bloch oscillations

Subjects: subject: Quantum Physics (quant-ph)

description: A quantum particle subjected to a constant force undergoes an accelerated motion following a parabolic path, which differs from the classical motion just because of wave packet spreading (quantum diffusion). However, when a periodic potential is added (such as in a crystal) the particle undergoes Bragg scattering and an oscillatory (rather than accelerated) motion is found, corresponding to the famous Bloch oscillations. Here we introduce an exactly-solvable quantum Hamiltonian model, corresponding to a generalized Wannier-Stark Hamiltonian $\hat{H}$, in which a quantum particle shows an intermediate dynamical behavior, namely an oscillatory motion superimposed to an accelerated one. Such a novel dynamical behavior is referred to as {\it accelerated Bloch oscillations}. Analytical expressions of the spectrum, improper eigenfunctions and propagator of the generalized Wannier-Stark Hamiltonian $\hat{H}$ are derived. Finally, it is shown that acceleration and quantum diffusion in the generalized Wannier-Stark Hamiltonian are prevented for Airy wave packets, which undergo a periodic breathing dynamics that can be referred to as {\it Airy-Bloch oscillations}.

description: The division which brings together R & D and the technical services of the NFB, of which Jimmy Fournier is the director, was mandated in 2008 to implement the digitization of filmic works. The objectives of this mission are to guarantee accessibility, restoration, but also preservation and conservation for future generations, past, current and future works in digital format. Eyes are insistently brought to the NFB for its expertise in the production of interactive works, but also in the archiving techniques developed by Jimmy and his team, which have been praised at international conferences. The NFB’s digitization plan that ensures the durability and accessibility of works integrates the 3 concepts of cataloguing, preserving assets sources and reproduce the experience. It requires expertise and advanced equipment. These concepts have been conceived with a view to applying them to new digital works and event with interactive complex digital content. The session will highlight the concepts, processes and technologies used for interactive digital works.
The Student Loan Debt Market: The role of federal student loan allocation on undergraduate student default rates
Creators: name: Rowe, Erin Alyse
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This study examines the effectiveness of federal student loan allocation and its role in student
loan default rates. The loan allocation method is represented by program loan limits imposed by
Congress. In addition to program loan limits, the study considers other educational and economic
institutional drivers that education research has been linked to student loan default rates. The
relationship between loan limits, other variables, and default rates is tested through a
multivariable regression analysis. The analysis suggests that program loan limits do not have a
significant effect on student loan default rates, but student loans are an effective means to help
students finance education. To conclude the study, I assess three potential loan allocation
methods as well as discuss my experience with the study and working with limited public data.

description: We study the fundamental limits on learning latent community structure in dynamic networks. Specifically, we study dynamic stochastic block models where nodes change their community membership over time, but where edges are generated independently at each time step. In this setting (which is a special case of several existing models), we are able to derive the detectability threshold exactly, as a function of the rate of change and the strength of the communities. Below this threshold, we claim that no algorithm can identify the communities better than chance. We then give two algorithms that are optimal in the sense that they succeed all the way down to this limit. The first uses belief propagation (BP), which gives asymptotically optimal accuracy, and the second is a fast spectral clustering algorithm, based on linearizing the BP equations. We verify our analytic and algorithmic results via numerical simulation, and close with a brief discussion of extensions and open questions.

description: The main task of this work is to find a fast and robust way to determine pp-collision time t0 at the SPD experiment. Using physics motivations, from the input flux of reconstructed particles' tracks we identify a subset of pions which is used to calculate the unbiased estimation of the event collision time. The uncertainty of the estimation is about 30 ps. This method is fast (less than 300 ns per event) and reliable, thus it will allow to process the high flux of input events at the SPD experiment.

description: Image token removal is an efficient augmentation strategy for reducing the cost of computing image features. However, this efficient augmentation strategy has been found to adversely affect the accuracy of CLIP-based training. We hypothesize that removing a large portion of image tokens may improperly discard the semantic content associated with a given text description, thus constituting an incorrect pairing target in CLIP training. To address this issue, we propose an attentive token removal approach for CLIP training, which retains tokens with a high semantic correlation to the text description. The correlation scores are computed in an online fashion using the EMA version of the visual encoder. Our experiments show that the proposed attentive masking approach performs better than the previous method of random token removal for CLIP training. The approach also makes it efficient to apply multiple augmentation views to the image, as well as introducing instance contrastive learning tasks between these views into the CLIP framework. Compared to other CLIP improvements that combine different pre-training targets such as SLIP and MaskCLIP, our method is not only more effective, but also much more efficient. Specifically, using ViT-B and YFCC-15M dataset, our approach achieves $43.9\%$ top-1 accuracy on ImageNet-1K zero-shot classification, as well as $62.7/42.1$ and $38.0/23.2$ I2T/T2I retrieval accuracy on Flickr30K and MS COCO, which are $+1.1\%$, $+5.5/+0.9$, and $+4.4/+1.3$ higher than the SLIP method, while being $2.30\times$ faster. An efficient version of our approach running $1.16\times$ faster than the plain CLIP model achieves significant gains of $+5.3\%$, $+11.3/+8.0$, and $+9.5/+4.9$ on these benchmarks.

description: 76. Cnidoscolus rupestris Fern.Casas, Fontqueria 55: 351 (2006). Type:— BRAZIL. Bahia: Estrada Xique-Xique– Vacarias ca. 11ºS, 43ºW, 14 October 1990, A. Freire Fierro, J.M. Martins, R. Moraes, P.L. da Rocha, M. Rodrigues, G. Sugliano & J.P. Yvert 1951 (holotype SPF).
 Distribution:— Brazil (regional endemic).
 Notes:— Fernández Casas (2006e) suggested that Cnidoscolus rupestris may be a hybrid between Cnidoscolus obtusifolius [as C. pubescens] and C. byssinus. It was distinguished from both species by having cylindrical glands along the leaf margin. It was further distinguished from Cnidoscolus byssinus by its 4-whorled androecium (vs. 6- whorled androecium). We believe that more study of the relationships among these three species would be beneficial.

Maternal Reminiscing Style and the Development of Autobiographical Memory in Children: The Impact of Auditory Comprehension
Creators: name: Veazey, Claire A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: A great amount of past research has revealed the positive impact that an elaborative maternal reminiscing style has on the development of autobiographical memory in children. However, this work has been limited to populations of children with typically developing language skills (Fivush, Haden, & Reese, 2006). The current study was designed to explore the associations between children’s language comprehension and their autobiographical memory on one hand, and their mothers’ style of reminiscing on the other. Using data from the Durham Child Health and Development Study, 113 children were grouped according to their auditory comprehension (AC) scores (high v. low) when the children were 36 months old. A mother-child reminiscing task was used to measure children’s autobiographical memory elaborations and maternal reminiscing style when children were 36 and 60 months old in order to assess the linkages both concurrently and longitudinally. Analyses revealed that (1) children’s AC at 36 months was significantly correlated with their autobiographical memory performance and maternal reminiscing style at both 36 and 60 months, and (2) autobiographical memory in children and maternal style at both time-points differed significantly as a function of the child’s language comprehension at 36 months. Both concurrently and longitudinally, children with lower language comprehension were likely to have lower autobiographical memory performance and less elaborative mothers. In contrast, children with high language comprehension were likely to have higher autobiographical memory performance and mothers who exhibited a more elaborative reminiscing style. By considering the amount of language that children comprehend, these results emphasize a need to account for child individual differences when examining the relations between maternal reminiscing style and autobiographical memory development over time.

description: JHOVE is an open source file format identification, validation and characterisation tool for digital preservation. It is maintained by the Open Preservation Foundation as part of the OPF reference toolset. JHOVE is one of the most widely-used digital preservation tools; it can be used as a stand alone toole or as part of a digital preservation workflow. It is also embedded in several off-the-shelf digital preservation products. While JHOVE is widely used by the digital preservation community new users often find it intimidating. This short tutorial is intended as a quick getting started guide for new JHOVE users, rather than experienced developers. his session will give participants a practical overview of JHOVE. We will begin with a brief background of JHOVE, its history, purpose and capabilities. There follows a demonstration, starting with downloading and installing JHOVE then running it over selected example files. We then examine the results while explaining what the error messages mean and where to go for more information.

description: In this paper, we investigate a non-interacting scalar field cosmology with an arbitrary potential using the $f$-deviser method that relies on the differentiability properties of the potential. Using this alternative mathematical approach, we present a unified dynamical system analysis at a scalar field's background and perturbation levels with arbitrary potentials. For illustration, we consider a monomial and double exponential potential. These two classes of potentials comprise the asymptotic behaviour of several classes of scalar field potentials, and, therefore, they provide the skeleton for the typical behaviour of arbitrary potentials. Moreover, we analyse the linear cosmological perturbations in the matterless case by considering three scalar perturbations: the evolution of the Bardeen potentials, the comoving curvature perturbation, the so-called Sasaki-Mukhanov variable, or the scalar field perturbation in uniform curvature gauge. Finally, an exhaustive dynamical system analysis for each scalar perturbation is presented, including the evolution of Bardeen potentials in the presence of matter.

The Impact of Motherhood, Childcare, and Location on Women's Wage Growth
Creators: name: Killian, Audra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This paper examines how motherhood, the use of childcare, and an individual’s geographic
location affects their wages for a fifteen year period using cross-sectional data. Incorporating
Gary Becker’s theory on the Gender Division of Labor (1985) and the feminist theory of the
‘second shift’, the paper aims to better understand how wages are affected, and what factors
contribute to that change. This paper also evaluates how an individual’s location, which highly
corresponds to their ideological values, affects their wages. By utilizing the NLSY79, this
analysis uses four empirical models, two Heckman Selection models to control for selection bias,
a Two Stage Least Squares to control for reverse causality, and a Fixed Model to control for
unobserved heterogeneity. This research reveals that similar to past research, each additional
child decrease wages by more than 10% and that paid childcare significantly increases women’s
wages. Those who live in urban areas see a 4% to 10% increase in wages across, and those who
live in the Northeastern US, which is much more urbanized than other areas of the US, earn more
than those in other regions.

description: Metallic quantum criticality is frequently discussed as a source for non-Fermi liquid behavior, but controlled theoretical treatments are scarce. Here we identify and study a novel magnetic quantum critical point in a two-dimensional antiferromagnet coupled to a three-dimensional environment of conduction electrons. Using sign-problem-free quantum Monte Carlo simulations and an effective field-theory analysis, we demonstrate that the quantum critical point is characterized by marginal Fermi liquid behavior. In particular, we compute the electrical resistivity for transport across the magnetic layer, which is shown to display a linear temperature dependence at criticality. Experimental realizations in Kondo heterostructures are discussed.

description: This communication focuses on the working group that Programme Vitam is leading on digital preservation. This interdepartmental work must enable each institution member to assume the Digital preservation of records and archives. The work takes form of : a feedback phase allowing to take advantage of experiences from the most advanced institutions on the subject, a practical experimentation phase and tests to evaluate existing tools and their results, on real lots of archives, and finally the realization of a structural study on organizational measures to set up so that the subject can be supported by the network of French archives. This communication would begin with the presentation of 3 concrete cases, to mark the spirits: a picture from the Cabinet Villepin Papers, French Prime Minister: not identifiable with DROID, not validable with JHOVE, but readable a Word document (minister paper): identifiable with DROID, not validable with Office validation tools, but readable an e-mail message from The 2015 United Nations Climate Change Conference (COP 21) extracted from a mail box with MailExtract: not identifiable with DROID, not validable for lack of existing module, but readable The evocation of these 3 cases would permit to question the strategy to be followed by archivists in terms of digital preservation: what actions, what decisions ? The discussion would therefore focus on the link between processes / tools of digital preservation / and also actors. The objective today is to rely on people who understand, use and interpret tools results and are able to define and implement a digital preservation policy, to know the purpose of the preservation process. For the vitam program it is essential to build a community that will use wisely, the tools developed or embedded by Vitam software solution. To this end, the program brings together and animates an interdepartmental community, but we need to share this experience more widely.
