description: North Carolina was one of the last colonies to have a printer working within its borders.  In 1749, the North Carolina General Assembly hired James Davis, of Virginia, to become the first printer in the state.  His duties were to print the public laws and distribute them to the proper officials.  His first printing, "The Journal of the House of Burgesses," was published in 1749 and was the first book printed in North Carolina.  He also performed private printing , with his press turning out the colony's first newspaper in 1751 and the first book by a North Carolina native in 1753.  His career was rocky at times, but he continued printing for thirty-two years until his retirement in 1781.  This paper examines the origins and career of James Davis, and the effect he had on North Carolina.  An annotated bibliography of all his known works is also included.

description: Technological developments facilitating the creation and dissemination of video information have resulted in an increase in free online material, with several sites directly targeting the needs of educators. Investments in the public school system's information technology resources have resulted in a gradual improvement in educators' ability to utilize online video for instruction. Testimonies from those in the education community as well as research from information scientists on educators' information use suggest the impact that these developments have had on educators' information seeking behavior. This study explores how 8th grade Social Studies teachers in Wake County are currently using online video resources, what search strategies they have developed to locate content appropriate for their instructional needs, and what the obstacles to their successful use of video are.

description: The purpose of this paper is to explore whether students with experience using archives search finding aids differently than students no experience.  A usability study was conducted using four different finding aids from four institution with eleven undergraduate students from the University of North Carolina at Chapel Hill.  The participants were recorded completing the tasks and were asked to describe their searching methods and the challenges they faced while completing the tasks during a stimulated recall session  The results found that students used a multitude of searching methods in their attempts to answer the questions.  The experienced users used more advanced techniques to find the answers but were less successful that the inexperienced participants on most of the tasks.  The participants also struggled with archival terminology as well as the websites themselves while searching for materials.  However, the participants were mostly successful in searching the library websites and locating finding aids.

description: We calculate the mean and variance of net-baryon number and net-electric charge distributions from Quantum Chromodynamics (QCD) using a next-to-leading order Taylor expansion in terms of temperature and chemical potentials. We compare these expansions with experimental data from STAR and PHENIX, determine the freeze-out temperature in the limit of vanishing baryon chemical potential, and, for the first time, constrain the curvature of the freeze-out line through a direct comparison between experimental data on net-charge fluctuations and a QCD calculation. We obtain a bound on the curvature coefficient, kappa_2^f < 0.011, that is compatible with lattice QCD results on the curvature of the QCD transition line.

description: The purpose of this paper is to record the liturgical order and tradition of the palladium icon of “Axion Estin” at the Protaton church of Mount Athos. After the presentation of the relevant manuscripts, we present the history and architecture of the church, as well as the history of the Icon. Then we analyze Her place in the Altar, the order of the Icon’s transfer in and out of the Altar and recount the events related to the dispute of the 1970s concerning Her permanent place in the Protaton. After that we record in detail the Orthros and the Divine Liturgy of the Bright Monday in the Protaton, as well as the Litany of the Icon during the same day. We continue with the order of the extraordinary Litanies of the Icon. Then we display the order of the Feast of the Icon on the 11th of June and we introduce the anecdotal canon of the Icon which is chanted during the Litany of the Bright Monday. Finally, we propose corrections of some rubrics we consider problematic and conclude with a photographic appendix.

description: This study is a questionnaire survey of practicing catalogers seeking to determine: how catalogers value flexibility in metadata schemas, how catalogers value flexibility in comparison to other qualities in metadata schemas, and how flexibility factors into catalogers¢ evaluations of MARC/AACR2 and simple Dublin Core. For the purpose of this study flexibility was operationalized into three different aspects: (1) the flexibility to represent information needs of different material types, (2) the flexibility to adapt to evolving cataloging standards, and (3) flexibility in rules to allow catalogers to utilize personal judgment. Twenty-one participants responded. They supported the first two aspects of flexibility, but supported having strict schema rules over flexible ones. Flexibility was considered in evaluations of metadata schemas, but not considered to be the most important quality of a metadata schema both generally and when evaluating Dublin Core and MARC/AACR2.
Digit Monitoring Task Results

description: Digit Monitoring Task (DMT) is a cognitive task in which a random integer number (from 1 to 9) is assigned to each volunteer, and the researcher instructs the volunteer to silently count, without using fingers, the number of times the digit is announced over a loudspeaker. The audio track used to carry out this experiment was identical for all participants, and it was transcribed so that the researcher had access to the correct digit. For each trial, a digit from the set of 1 to 9 was drawn without replacement.
 At the end of the experiment, the researcher asked the participant how many times he heard the drawn digit. Here we present the results by group and the original audio track.

Generalized maximum entropy approach to quasi-stationary states in long range systems

description: Systems with long-range interactions display a short-time relaxation towards Quasi Stationary States (QSS) whose lifetime increases with the system size. In the paradigmatic Hamiltonian Mean-field Model (HMF) out-of-equilibrium phase transitions are predicted and numerically detected which separate homogeneous (zero magnetization) and inhomogeneous (nonzero magnetization) QSS. In the former regime, the velocity distribution presents (at least) two large, symmetric, bumps, which cannot be self-consistently explained by resorting to the conventional Lynden-Bell maximum entropy approach. We propose a generalized maximum entropy scheme which accounts for the pseudo-conservation of additional charges, the even momenta of the single particle distribution. These latter are set to the asymptotic values, as estimated by direct integration of the underlying Vlasov equation, which formally holds in the thermodynamic limit. Methodologically, we operate in the framework of a generalized Gibbs ensemble, as sometimes defined in statistical quantum mechanics, which contains an infinite number of conserved charges. The agreement between theory and simulations is satisfying, both above and below the out of equilibrium transition threshold. A precedently unaccessible feature of the QSS, the multiple bumps in the velocity profile, is resolved by our new approach.
Just Say Hello: Proactive Courtesy as a Catalyst for Customer Loyalty in Public Libraries

description: The purpose of this study was to explore the proactive use of basic courtesies in public library service as a potential positive influence on customer satisfaction and loyalty. Four small- to medium-sized public libraries in North Carolina and Virginia were surveyed before and after implementing a program to emphasize three basic customer service courtesies: greeting customers, acknowledging customers immediately upon their arrival at the point of service, and closing every transaction with a valediction or expression of thanks. Three of the four participating libraries showed improved scores in staff and service quality and evidence of increased customer loyalty after successfully implementing the basic courtesy program. The remaining library received lower scores for satisfaction and loyalty after showing a decrease in performance of basic courtesies. These small and easy-to-implement courtesies seem to positively affect customer perceptions of library service.

description: This paper documents a minimal-investment project to migrate legacy exhibits of the State Archives of North Carolina and the State Library of North Carolina into a new exhibiting platform. The Drupal-based platform links with the institutions' existing discovery platform (CONTENTdm) and offers robust means for centrally managing and creating exhibits. Through discussion of this project and the surrounding literature, the paper argues that digital exhibits remain a vital and sustainable tool for libraries and archives, helping institutions to fulfill their role not only as data disseminators, but as active agents of mediation and interpretation. The paper provides specific documentation of tools used in the project, detailed time logs, and project cost assessments.

description: The extensive work in AMAP on Arctic contamination by Persistent Organic Pollutants (POPs) illustrates the strong state of knowledge and data on contaminants in biota and water, but also highlights a stark data gap regarding contaminants in Arctic soils, particularly below the permafrost table. Here, we describe the work carried out on analyses and scaling of contaminants. A key aspect for being able to deliver geospatial databases is identifying which landscape properties we can use to scale the measured contaminant levels. Soils in the Canadian study area at Komakuk Beach (Yukon, CA) have been sampled and analysed for hexachlorobenzene (HCB), 54 polychlorinated biphenyl congeners (PCBs) and 22 individual polycyclic aromatic hydrocarbons (PAHs) in 89 active layer and permafrost core samples. The concentrations have been determined by using Thermo Scientific Dionex ASE 350 and Trace 1310 GC coupled with TSQ9000 TQMS, Thermo Scientific, at CNR-ISP Venice, Italy. The statistical parameters of data on HCB concentrations describe its scarce presence, with limited occurrences linked to the organic rich soil horizons. Overall, Σ54PCBs in soils collected in the catchment area were in the range from 0 to 5.33 pg/g. Both the content of individual PAHs and their total concentration vary widely from 0 to 121ng/g. The contribution of individual PAHs to the total amount is not the same and depends on the concentration of heavy 5–6-nuclear polyarenes and mainly 6-nuclear benzo[ghi]perylene. Our results show that the vertical distribution patterns of light 2–4-nuclear and heavy 5–6-nuclear PAHs are differentiated. Every class of OC is present in the deeper permafrost core portions only in High Centre Polygon (HCP) landform class, highlighting the role of hydrology and percolation in the contaminant distribution in permafrost soils and how these variables are enhanced in (semi-)degraded permafrost landforms. The model equations have been applied on the carbon content prediction maps for each study area, to export a first attempt of upscaling feasible for small coastal catchments in polygonal tundra environment. Contaminant concentrations ranges were calculated for different depth from 0 to 1 meter below the ground, following the carbon content prediction maps from Wagner et al. (sub.)

description: This paper describes a two-part study attempting to correlate music genre assignments  performed by two primary, yet disparate groups: the music industry and consumers of  popular music.  An online survey was conducted, aimed at evaluating the latter group's perception of  music genre. The sample of the survey consisted of 15 UNC-CH students affiliated with  the music department. Concurrently, a series of genre classification experiments were  conducted on several corpora of music reviews harvested from authoritative, online  review websites. Results of the survey were subsequently triangulated with a portion of  the music review corpora in a final genre classification experiment.  The genre classification experiments were quite successful, yielding a maximum of 91%  accuracy using web-based data alone. The effect of weighting schemes and procedural  modifications on experimental accuracy rates are discussed, as are qualitative evaluations  of participants' responses to the survey.
The spectral function of the Tomonaga-Luttinger model revisited: power laws and universality

Publisher: name: arXiv
Year: 2015
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We reinvestigate the momentum-resolved single-particle spectral function of the Tomonaga-Luttinger model. In particular, we focus on the role of the momentum-dependence of the two-particle interaction V(q). Usually, V(q) is assumed to be a constant and integrals are regularized in the ultraviolet `by hand' employing an ad hoc procedure. As the momentum dependence of the interaction is irrelevant in the renormalization group sense this does not affect the universal low-energy properties of the model, e.g. exponents of power laws, if all energy scales are sent to zero. If, however, the momentum k is fixed away from the Fermi momentum k_F, with |k-k_F| setting a nonvanishing energy scale, the details of V(q) start to matter. We provide strong evidence that any curvature of the two-particle interaction at small transferred momentum q destroys power-law scaling of the momentum resolved spectral function as a function of energy. Even for |k-k_F| much smaller than the momentum space range of the interaction the spectral line shape depends on the details of V(q). The significance of our results for universality in the Luttinger liquid sense, for experiments on quasi one-dimensional metals, and for recent attempts to compute the spectral function of one-dimensional correlated systems taking effects of the curvature of the single-particle dispersion into account (nonlinear Luttinger liquid phenomenology) is discussed.

description: This study aims at measuring the readability level of selected recommended consumer health books. National literacy studies suggest that about half of the United States population has low functional literacy levels. Health literacy is a specialized aspect of literacy and is often complicated by technical language and barriers including psychological stress. Books for analysis were selected from Library Journal's "Best Consumer Health Books of 2006" list. The readability of text was tested using the Simple Measure Of Gobbledygook (SMOG) and Flesch-Kincaid (FK) formulas. Results found that no books tested below a SMOG grade level of ten, the average FK grade was also ten. The results correspond to high school level readability--higher than the average consumer's estimated reading level. The findings suggest that even recommended consumer health books are written at a level that is beyond the reading comprehension of about half of the population. Impacts on collection development are discussed.

This study examines the relationship between background knowledge about music and track co-occurrence frequency in users’ music listening history and builds a multiple linear regression model to predict the track co-occurrence. So given a seed track, the model can find out which track is most likely to co-occur. A simple objective evaluation compares predicted track with tracks in the users’ listening history. 13 out of 15 test tracks find the highest rank predicted track in the same listening history.

description: We investigate the regularization-scheme dependence of scattering amplitudes in massless QCD and find that the four-dimensional helicity scheme (FDH) and dimensional reduction (DRED) are consistent at least up to NNLO in the perturbative expansion if renormalization is done appropriately. Scheme dependence is shown to be deeply linked to the structure of UV and IR singularities. We use jet and soft functions defined in soft-collinear effective theory (SCET) to efficiently extract the relevant anomalous dimensions in the different schemes. This result allows us to construct transition rules for scattering amplitudes between different schemes (CDR, HV, FDH, DRED) up to NNLO in massless QCD. We also show by explicit calculation that the hard, soft and jet functions in SCET are regularization-scheme independent.

description: Liquid film flow is the dominant flow regime in distillation and absorption processes within structured packings. Extensive research has been carried out to improve the understanding of the involved fluid dynamics. Up to now, these investigations mainly focused on gravity-stabilized film flow, i.e., the liquid phase flows over a packing in counter-current flow with a gas phase. In contrast, gravity-destabilized film flow is studied much less frequently although this type of flow applies to about half of the cases in a column with structured packings. Here, the liquid runs along the underside of the packing, also in counter-current flow with the gas phase. To close the gap in the experimental data, this contribution investigates the fundamental fluid dynamics of gravity-destabilized liquid film flows on a smooth plate, a 2D wave texture, and a 3D pyramidal texture. Results on critical convective inclination angle, drained liquid mass flow, and liquid film thickness without counter-current gas flow are reported and compared to numerical results from literature. In the experiments, the Reynolds number is varied from 28.4 to 113.5 using a surfactant-modified aqueous system. The 2D structure showed decreased liquid flow stability compared to the smooth surface. However, the 3D structure seems to have a stabilizing effect on the flow.

description: This study looks at the placement of current popular fiction in academic libraries to determine whether popular fiction titles are places within the context of the rest of the collection or separated into browsing or popular collections.  While other studies have examined the extent to which academic libraries are collecting popular material, they have not considered what happens to those materials once they have been collected.  The study concludes that academic libraries have widely different approaches to both collecting and placing current popular fiction.
Temporal Transition from Illusory Conjunctions to Object Recognition

description: Intuitive explanations of the visual system of the brain are challenged by the psychological observation of illusory conjunctions. Theories and computational models exist both for regular object recognition and for illusory conjunctions. But how does the brain transition from the state of illusory conjunctions to correct object recognition? My master thesis addresses this question by investigating the time course of object perception and the transition from illusory conjunction to object recognition. To this end, I propose a neural network architecture and simulate it with spiking neurons. The main result is that bumps form first independently in different feature maps in the primary visual cortex V1 giving rise to illusory conjunctions. Within around 100 ms of visual stimulus presentation, the different feature maps communicate via a location map in MT such that they converge to the representation of the same object. With its biological plausibility, mathematical foundation, computationally efficient implementation, my spiking neuron network is a step toward an understanding of vision. It could help building a neuromorphic visual system.

description: We define an appropriate problem for benchmarking dust emissivity calculations in the context of radiative transfer (RT) simulations, specifically including the emission from stochastically heated dust grains. Our aim is to provide a self-contained guide for implementors of such functionality, and to offer insights in the effects of the various approximations and heuristics implemented by the participating codes to accelerate the calculations. The benchmark problem definition includes the optical and calorimetric material properties, and the grain size distributions, for a typical astronomical dust mixture with silicate, graphite and PAH components; a series of analytically defined radiation fields to which the dust population is to be exposed; and instructions for the desired output. We process this problem using six RT codes participating in this benchmark effort, and compare the results to a reference solution computed with the publicly available dust emission code DustEM. The participating codes implement different heuristics to keep the calculation time at an acceptable level. We study the effects of these mechanisms on the calculated solutions, and report on the level of (dis)agreement between the participating codes. For all but the most extreme input fields, we find agreement within 10% across the important wavelength range from 3 to 1000 micron. We conclude that the relevant modules in RT codes can and do produce fairly consistent results for the emissivity spectra of stochastically heated dust grains.

Filled-in vs. Outline Icons:  The Impact of Icon Style on Usability

description: This study sought to determine whether single-color, "flat" icons would be more quickly
and accurately selected by users when presented in either a filled-in or outline style. An
application was developed that allowed participants to take a test measuring their speed
and accuracy in selecting prompted icons from an array of distractors. The test was made
available on the web and was completed by 1,260 participants. Averaged across the 20
unique icon forms used in the test, the outline style led to slightly longer task times, but
only when icons were displayed in white against a black background. For individual
icons, the effects of icon style were inconsistent and, except for a few exceptions, quite
small. This study concluded that one icon style is not objectively better than the other.

description: Homogeneous and isotropic, nonsingular, bouncing world models are designed to evade the initial singularity at the beginning of the cosmic expansion. Here, we study the thermodynamics of the subset of these models governed by general relativity. Considering the entropy of matter, radiation and that the entropy of the apparent horizon is proportional to its area, we argue that these models do not respect the generalised second law of thermodynamics, also away from the bounce.

A consistent interface element formulation for geometrical and material nonlinearities

description: Decohesion undergoing large displacements takes place in a wide range of applications. In these problems, interface element formulations for large displacements should be used to accurately deal with coupled material and geometrical nonlinearities. The present work proposes a consistent derivation of a new interface element for large deformation analyses. The resulting compact derivation leads to a operational formulation that enables the accommodation of any order of kinematic interpolation and constitutive behavior of the interface. The derived interface element has been implemented into the finite element codes FEAP and ABAQUS by means of user-defined routines. The interplay between geometrical and material nonlinearities is investigated by considering two different constitutive models for the interface (tension cut-off and polynomial cohesive zone models) and small or finite deformation for the continuum. Numerical examples are proposed to assess the mesh independency of the new interface element and to demonstrate the robustness of the formulation. A comparison with experimental results for peeling confirms the predictive capabilities of the formulation.

description: Information literacy competency involves the ability to understand the need for information and then to successfully find, evaluate, and use it. As information has become more easily accessible and abundant on the Internet, information literacy competencies have become increasing important in academic disciplines. Health-related disciplines, especially public health, have been slower to realize the importance of these competencies. A pilot project for the University of North Carolina at Chapel Hill's (UNC) Health Sciences Library, this study uses a survey questionnaire to assess the baseline information literacy competencies of students in UNC's School of Public Health. The results showed that a majority of graduate students demonstrated a high proficiency in information literacy competencies, but that a significant number of graduate students had important weaknesses in them. The results could be used to inform approaches to information literacy competencies' instruction and the design of future assessments.
