Electronic information resources

description: This is an investigation of perpetual access rights and archival provisions for licensed electronic resources at The University of North Carolina at Chapel Hill. Perpetual access refers to post-cancellation access to e-resources. Archival provisions specify the format of perpetual access to these resources. E-resources, including e-journals and databases, make up the majority of many libraries’ collections budgets. Tightening budgets may force librarians to make the difficult decision to cancel large e-journal packages or other subscribed resources. Negotiating strong perpetual access clauses into license agreements ensures continued access to these resources. In addition, provider participation in third-party archiving services allows for long-term preservation and access. This investigation examines the state of perpetual access and archival provisions for licensed e-resources at UNC-Chapel Hill.

description: This study evaluates the homepages of government websites in the three democratic nations of Australia, the United Kingdom, and the United States to determine the level of disability access in each country. This survey was conducted to determine which country has the overall lowest level of accessibility, which areas need the most improvement, and which areas have strong compliancy levels. Twenty-two websites from each of the top levels of government in each of the three countries (66 total websites) were examined for compliance to current disability standards as set forth by the World Wide Web Consortium's Web Accessibility Initiative (WAI). The websites were evaluated using a questionnaire developed to test for adherence to the WAI's fourteen guidelines. The results show that, despite legislative efforts mandating disability access on government websites, these sites are not fully accessible. The study found the United States to have the highest levels of accessibility, followed by Australia, with the United Kingdom at the lowest levels of accessibility.
Metropolitan Atlanta Jewish Population Study
Creators: name: Atlanta Jewish Federation
Publisher: name: Roper Center for Public Opinion Research
Year: 2019

description: The Data File for Atlanta 1983 (and a printout of frequencies based on this data file) have been removed from the public portion of the Data Bank website as of June, 2007. First, the data file is extremely 'dirty,' with almost every variable having 'incorrect punches' which are not correctable at this time, and would need to be placed into missing data. Second, many variables remain unlabeled, and many data entries in other variables appear to be totally inappropriate. Third, the data file available to the Data Bank since 1996 contains only 477 cases, while written materials indicate that there should be 579 interviews in the file. Finally, the Main Report methodology summary is sufficiently detailed to provide researchers with sufficient information to evaluate the survey's quality, and to provide needed data. It is unlikely that reanalysis of the 1984 data file currently available will add anything of use to the reported data. Upon special request, the 1984 Atlanta data file (and the frequencies) are available to registered Data Bank members. Extreme caution should be used with this data set: the data file totals do not match those found in the published report, and there is no "weight" variable in the data file.

description: First results are reported on the ground state configurations of the neutron-rich $^{29,30}$Na isotopes, obtained via Coulomb dissociation (CD) measurements as a method of the direct probe. The invariant mass spectra of those nuclei have been obtained through measurement of the four-momentum of all decay products after Coulomb excitation on a $^{208}Pb$ target at energies of 400-430 MeV/nucleon using FRS-ALADIN-LAND setup at GSI, Darmstadt. Integrated Coulomb-dissociation cross-sections (CD) of 89 $(7)$ mb and 167 $(13)$ mb up to excitation energy of 10 MeV for one neutron removal from $^{29}$Na and $^{30}$Na respectively, have been extracted. The major part of one neutron removal, CD cross-sections of those nuclei populate core, in its' ground state. A comparison with the direct breakup model, suggests the predominant occupation of the valence neutron in the ground state of $^{29}$Na${(3/2^+)}$ and $^{30}$Na${(2^+)}$ is the $d$ orbital with small contribution in the $s$-orbital which are coupled with ground state of the core. The ground state configurations of these nuclei are as $^{28}$Na$_{gs (1^+)\otimesν_{s,d}$ and $^{29}$Na$_{gs}(3/2^+)\otimesν_{ s,d}$, respectively. The ground state spin and parity of these nuclei, obtained from this experiment are in agreement with earlier reported values. The spectroscopic factors for the valence neutron occupying the $s$ and $d$ orbitals for these nuclei in the ground state have been extracted and reported for the first time. A comparison of the experimental findings with the shell model calculation using MCSM suggests a lower limit of around 4.3 MeV of the sd-pf shell gap in $^{30}$Na.

description: This study was undertaken in order to examine the extent to which academic libraries that have undertaken LibQUAL+ surveys are engaging in internal marketing initiatives. Six personnel librarians from academic libraries that participated in the 2000 or 2001 rounds of LibQUAL+ surveys answered a series of interview questions designed to gather qualitative information on the types of programs and initiatives that academic libraries have in place to support, recognize, and reward excellent service delivery. Interviews with the six librarians revealed that although the participating libraries do not specifically identify the various programs and initiatives they have in place to promote their respective service missions and goals as internal marketing, they are engaged in internal marketing practices. Interviews also revealed that the libraries are using three major channels to practice internal marketing in their libraries. These channels operate through a library's organizational structure, its communication methods, and its recognition and rewards programs.

description: For exploring the application potential of coherent soft x-ray (SXR) and extreme ultraviolet radiation (XUV) provided by high-harmonic generation, it is important to characterize the central output parameters. Of specific importance are pulse-to-pulse (shot-to-shot) fluctuations of the high-harmonic output energy, fluctuations of the direction of the emission (pointing instabilities), and fluctuations of the beam divergence and shape that reduce the spatial coherence. We present the first single-shot measurements of waveguided high-harmonic generation in a waveguided (capillary-based) geometry. Using a capillary waveguide filled with Argon gas as the nonlinear medium, we provide the first characterization of shot-to-shot fluctuations of the pulse energy, of the divergence and of the beam pointing. We record the strength of these fluctuations vs. two basic input parameters, which are the drive laser pulse energy and the gas pressure in the capillary waveguide. In correlation measurements between single-shot drive laser beam profiles and single-shot high-harmonic beam profiles we prove the absence of drive laser beam-pointing-induced fluctuations in the high-harmonic output. We attribute the main source of high-harmonic fluctuations to ionization-induced nonlinear mode mixing during propagation of the drive laser pulse inside the capillary waveguide.

description: This study explored how individuals categorized on handedness (being left or right hand dominant) reacted to having the vertical scroll bar of a web browser relocated to the left side of the screen. The relocation of the vertical scroll bar served as an alternative to the relocation of the prominent left aligned main navigation menu for most websites. Fifteen participants were recruited for the study. Each participant interacted with two versions of a web site in a modified browser to complete a set of ten short tasks. Participants completed tasks by interacting with a traditional and non-traditional vertical browser alignment. Left and right-handed participants were determined to be strikingly different in operation. Vertical scroll relocation produced some interesting results and responses.

description: This case study describes how nine American librarians who participated in a short-term library development program run by the World Library Partnership carried their senses of professional identity and knowledge into new temporary work roles and library settings in South Africa. In-depth interviews with these volunteers revealed several important dynamics in which professional identity and knowledge came into play. These included (1) the interaction among expectations concerning library-related work, the volunteer librarian role, and the reality of these factors in South Africa; and (2) the role of prior experiences - both professional and non-professional - in adapting to unknown and unfamiliar situations. Additionally, this study considered the accomplishments volunteers perceived in their experiences and the various ways their senses of personal and professional identity have been affected by the program.

We give a criterion for the faithful flatness and use it to show the faithful flatness of an arbitrary flat Hopf algebra upon its finite normal Hopf subalgebra. For the projectivity of a projective Hopf algebras we need some finiteness condition in terms of the module of integral. In particular we show the the module of integral has rank one.

description: Dilute magnetic semiconductors (DMSs) show great promise for applications in spin-based electronics, but in most cases continue to elude explanations of their magnetic behavior. Here, we combine quantitative x-ray spectroscopy and Anderson impurity model calculations to study ferromagnetic Fe-substituted In$_2$O$_3$ films, and we identify a subset of Fe atoms adjacent to oxygen vacancies in the crystal lattice which are responsible for the observed room temperature ferromagnetism. Using resonant inelastic x-ray scattering, we map out the near gap electronic structure and provide further support for this conclusion. Serving as a concrete verification of recent theoretical results and indirect experimental evidence, these results solidify the role of impurity-vacancy coupling in oxide-based DMSs.

Quantum corrections to the gravitational potentials of a point source due to conformal fields in de Sitter

description: We derive the leading quantum corrections to the gravitational potentials in a de Sitter background, due to the vacuum polarization from loops of conformal fields. Our results are valid for arbitrary conformal theories, even strongly interacting ones, and are expressed using the coefficients $b$ and $b'$ appearing in the trace anomaly. Apart from the de Sitter generalization of the known flat-space results, we find two additional contributions: one which depends on the finite coefficients of terms quadratic in the curvature appearing in the renormalized effective action, and one which grows logarithmically with physical distance. While the first contribution corresponds to a rescaling of the effective mass, the second contribution leads to a slower fall-off of the Newton potential at large distances, and is potentially measurable.

Symmetries of general non-Markovian Gaussian diffusive unravelings
Creators: name: Budini, Adrian A.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)

description: By using a condition of average trace preservation we derive a general class of non-Markovian Gaussian diffusive unravelings [L. Diosi and L. Ferialdi, Phys. Rev. Lett. \textbf{113}, 200403 (2014)], here valid for arbitrary non-Hermitian system operators and noise correlations. The conditions under which the generalized stochastic Schrodinger equation has the same symmetry properties (invariance under unitary changes of operator base) than a microscopic system-bath Hamiltonian dynamics are determined. While the standard quantum diffusion model (standard noise correlations) always share the same invariance symmetry, the generalized stochastic dynamics can be mapped with an arbitrary bosonic environment only if some specific correlation constraints are fulfilled. These features are analyzed for different non-Markovian unravelings equivalent in average. Results based on quantum measurement theory that lead to specific cases of the generalized dynamics [J. Gambetta and H. M. Wiseman, Phys. Rev. A \textbf{66}, 012108 (2002)]\ are studied from the perspective of the present analysis.

description: This paper describes an exploratory study of undergraduate students' success in locating U.S. government information on the Web. The purpose of this study was to gain a better understanding of how undergraduates look for government information on the Web and to examine the problems they encounter.  Ten undergraduate students at the University of North Carolina at Chapel Hill were recruited to participate in Web searching sessions. Participants were required to locate documents and find answers to imposed questions requiring U.S. government information available on the Web. Participants answered an average of 1.7 out of four (42.5%) questions correctly. They had greater success with predictable source questions than with unpredictable source questions. Participants initiated 35 out of 40 total search tasks with a Google search. Domain knowledge, working with dates, and locating key government search interfaces such as GPO Access, Thomas, American FactFinder, and the National Center for Education Statistics homepage affected success.

description: We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J1946+274 is a transient X-ray binary consisting of a Be-type star and a neutron star with a 15.75 s pulse period in a 172 d orbit with 2-3 outbursts per orbit during phases of activity. We improve the orbital solution using data from multiple instruments. The X-ray spectrum can be described by an absorbed Fermi-Dirac cutoff power law model along with a narrow Fe K line at 6.4 keV and a weak Cyclotron Resonance Scattering Feature (CRSF) at ~35 keV. The Suzaku data are consistent with the previously observed continuum flux versus iron line flux correlation expected from fluorescence emission along the line of sight. However, the observed iron line flux is slightly higher, indicating the possibility of a higher iron abundance or the presence of non-uniform material. We argue that the source most likely has only been observed in the subcritical (non-radiation dominated) state since its pulse profile is stable over all observed luminosities and the energy of the CRSF is approximately the same at the highest (~$5 \times 10^{37} $erg s$^{-1}$) and lowest (~$5 \times 10^{36} $erg s$^{-1}$) observed 3-60 keV luminosities.

description: Goulden and Jackson (1996) introduced, using Jack symmetric functions, some multivariate generating series $ψ(x, y, z; t, 1+β)$ that might be interpreted as a continuous deformation of the generating series of rooted hypermaps. They made the following conjecture: the coefficients of $ψ(x, y, z; t, 1+β)$ in the power-sum basis are polynomials in $β$ with nonnegative integer coefficients (by construction, these coefficients are rational functions in $β$). We prove partially this conjecture, nowadays called $b$-conjecture, by showing that coefficients of $ψ(x, y, z; t, 1+ β)$ are polynomials in $β$ with rational coefficients. A key step of the proof is a strong factorization property of Jack polynomials when the Jack-deformation parameter $α$ tends to $0$, that may be of independent interest.

description: Older adults are increasingly acquiring smartphones. But acquiring smartphones can be difficult, and little is known about the particular challenges of older adults who are additionally blind or losing their vision. We shed light on the social and technical aspects of acquiring smartphones with vision loss, based on deep qualitative interviews with 22 blind or low vision (BLV) older adults aged 60 and over. Through our grounded theory analysis, we found that BLV older adults experience liminality as they acquire smartphones and transition through re-acquiring smartphones as they become blind, and they can transition through liminality by participating in mutual aid within the blind community. We contribute the notion of "Intersecting Liminality," which explains the marginalizing experience of simultaneously transitioning through vision loss, aging, and technology acquisition. We contend that Intersecting Liminality can serve as a framework that centers the dynamic nature of disability to help our community generate a more nuanced understanding of technology acquisition and more effective assistive interventions.

description: A model of two consumer-resource systems linked by interspecific interference competition of consumers is considered. The basic assumption of the model is that the dynamics of the resource is much slower than that of the consumer. In the absence of interaction each consumer-resource pair has a unique stable steady state which is completely nonoscillatory. When weakly coupled, the consumer-resource pairs are shown to exhibit sustained low-frequency synchronous antiphase relaxation oscillations.

subject: 76B15, 35Q35

description: A single incompressible, inviscid, irrotational fluid medium bounded above by a free surface is considered. The Hamiltonian of the system is expressed in terms of the so-called Dirichlet-Neumann operators. The equations for the surface waves are presented in Hamiltonian form. Specific scaling of the variables is selected which leads to a KdV approximation with higher order nonlinearities and dispersion (higher-order KdV-type equation, or HKdV). The HKdV is related to the known integrable PDEs with an explicit nonlinear and nonlocal transformation.

Library schools--Curriculum

description: This study examines the educational backgrounds of full-time faculty members at a sample of ALA-accredited library schools in the United States. Data was gathered for 795 faculty members over a fifteen year period and changes in the composition of faculties with regard to educational background in library and information sciences were tracked.  The faculties of 33 library schools were studied. While the percentage of faculty with LIS doctorate degrees has increased, so has the percentage of faculty with no earned degree in LIS. This change has resulted in a sizable portion of LIS faculty coming from outside of the field, particularly in LIS schools with doctoral programs. The disciplines from which these faculty members come was analyzed over time. Implications for curriculum in LIS programs are discussed, along with recommendations for LIS programs.

description: Im Rahmen dieser Arbeit wurde eine Tinte für die additive Fertigung, speziell das Tintenstrahldrucken, entwickelt, welche als passivierender Dünnschichtkontakt in Silizium-Solarzellen eingesetzt werden soll. Die Tinte (AQ01), die hauptsäch-lich aus dem präkeramischen Polymer Polyorganosilazan besteht, wurde hinsichtlich ihrer rheologischen, strukturellen und thermischen Eigenschaften untersucht. Anschließend wurde die Druckbarkeit von Dünnschichten mittels Tinten-strahldruckers geprüft. Die Ergebnisse zeigen, dass die entwickelte Tinte die Anforderungen des Tintenstrahldruckers erfüllt, da sie sowohl eine niedrige Viskosität (unter 20 mPa∙s) als auch Newton‘sches Verhalten bei hohen Scherraten aufweist. Zusätzlich hat die Tinte eine Oberflächenspannung von 21 mN/m2. Die entwickelte Tinte konnte photochemisch vernetzt werden und anschließend bei hohen Temperaturen (950 °C) in eine amorphe Keramik überführt werden. Anhand der FTIR-Spektren konnte die chemische Struktur der Tinte sowohl nach der Polymerisation als auch nach der Pyrolyse untersucht werden. Die Ergebnisse zeigen, dass die Vernetzung überwiegend über radikalische Polymerisation der Vi-nylgruppe abgelaufen ist. Darüber hinaus handelt es sich bei der resultierenden Keramik um Siliziumcarbonitrid (SiCN). Die keramische Ausbeute liegt bei ungefähr 76 %.

description: Flexible information routing fundamentally underlies the function of many biological and artificial networks. Yet, how such systems may specifically communicate and dynamically route information is not well understood. Here we identify a generic mechanism to route information on top of collective dynamical reference states in complex networks. Switching between collective dynamics induces flexible reorganization of information sharing and routing patterns, as quantified by delayed mutual information and transfer entropy measures between activities of a network's units. We demonstrate the power of this generic mechanism specifically for oscillatory dynamics and analyze how individual unit properties, the network topology and external inputs coact to systematically organize information routing. For multi-scale, modular architectures, we resolve routing patterns at all levels. Interestingly, local interventions within one sub-network may remotely determine non-local network-wide communication. These results help understanding and designing information routing patterns across systems where collective dynamics co-occurs with a communication function.

Classifying self-gravitating radiations
Creators: name: Kim, Hyeong-Chan
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study a static system of self-gravitating radiations confined in a sphere by using numerical and analytical calculations. Due to the scaling symmetry of radiations, most of main properties of a solution can be represented as a segment of a solution curve on a plane of two-dimensional scale invariant variables. We define an `approximate horizon' (AH) from the analogy with an apparent horizon. Any solution curve contains a unique point which corresponds to the AH. A given solution is uniquely labelled by three parameters representing the solution curve, the size of the AH, and the sphere size, which are an alternative of the data at the outer boundary. Various geometrical properties including the existence of an AH and the behaviors around the center can be identified from the parameters. We additionally present an analytic solution of the radiations on the verge of forming a blackhole. Analytic formulae for the central mass of the naked singularity are given.

Nilpotent, algebraic and quasi-regular elements in rings and algebras

description: We prove that an integral Jacobson radical ring is always nil, which extends a well known result from algebras over fields to rings. As a consequence we show that if every element x of a ring R is a zero of some polynomial p_x with integer coefficients, such that p_x(1)=1, then R is a nil ring. With these results we are able to give new characterizations of the upper nilradical of a ring and a new class of rings that satisfy the Köthe conjecture, namely the integral rings.

Usability testing

description: This paper presents the results to supplement previous work to include testing 7" display devices (mini tablet) and compare its performance to tablet and phone directly (and to desktop indirectly via the previous results). The study was only concerned with the within documentation navigation using scrolling interaction to evaluate how these methods affect task efficiency on seven inch display (iPad mini). Overall, the quantitative data was reflected by task execution time and qualitative data was analyzed using task load and usability data measures. Findings indicated that most users would likely spend more time in searching task on mobile devices they carry around (phone), which echoed the conclusion by Laura Marcial's previous research. In terms of seven inch tablet, it performed better than phone and more or less equally to the tablet.

description: In this paper, we propose an approach for an application of Bayesian optimization using Sequential Monte Carlo (SMC) and concepts from the statistical physics of classical systems. Our method leverages the power of modern machine learning libraries such as NumPyro and JAX, allowing us to perform Bayesian optimization on multiple platforms, including CPUs, GPUs, TPUs, and in parallel. Our approach enables a low entry level for exploration of the methods while maintaining high performance. We present a promising direction for developing more efficient and effective techniques for a wide range of optimization problems in diverse fields.

description: We study the ionization dynamics of Ar clusters exposed to ultrashort near-infrared (NIR) laser pulses for intensities well below the threshold at which tunnel ionization ignites nanoplasma formation. We find that the emission of highly charged ions up to Ar$^{8+}$ can be switched on with unit contrast by generating only a few seed electrons with an ultrashort extreme ultraviolet (XUV) pulse prior to the NIR field. Molecular dynamics simulations can explain the experimental observations and predict a generic scenario where efficient heating via inverse bremsstrahlung and NIR avalanching are followed by resonant collective nanoplasma heating. The temporally and spatially well-controlled injection of the XUV seed electrons opens new routes for controlling avalanching and heating phenomena in nanostructures and solids, with implications for both fundamental and applied laser-matter science.
