Elementary School Libraries North Carolina

description: This research study examines elementary school media specialists' use of web resources in teaching information literacy skills. In this study, the school library media center web sites from 111 elementary schools in two North Carolina school districts were analyzed. The criteria that were used to evaluate each SLMC web page were developed based on a survey of professional literature. Most of the examined web sites maintained a list of recommended web resources for students. Based on the results of this content analysis, eight currently-practicing elementary school library media specialists were selected and interviewed. The interview responses helped to identify recommended practices for incorporating web resources into the curriculum. Specifically, schools that followed the North Carolina IMPACT model displayed the best examples of integrating web resources. Schools with dedicated staff members who maintain the school's technology and facilitate its integration into the curriculum presented higher levels of collaboration. This study suggests that the addition of a technology specialist as well as the administrative support of the partnership between the media specialist and technology specialist is integral to the promotion of web resources. Additionally, the study showed that the media specialist's interest and knowledge of web resources did not always translate into higher levels of collaborations with teachers. Successful collaborations more often resulted from the media specialist's efforts to promote his/her skills and services.

description: We present the theoretical study of the process $χ_{c0}(1P)\to\barΣΣπ$ decay, by taking into account the $πΣ$ and $π\barΣ$ final state interactions of the final meson-baryon pair based on the chiral unitary approach. We show that the process filters the isospin $I=1$ in the $πΣ$ channel and offers a reaction to test the existence of an $I=1$ state with strangeness $S=-1$ and spin-parity $J^p=1/2^-$ around the $\bar KN$ threshold predicted by some theories and supported by some experiments.

Improving prediction performance of stellar parameters using functional models

description: This paper investigates the problem of prediction of stellar parameters, based on the star's electromagnetic spectrum. The knowledge of these parameters permits to infer on the evolutionary state of the star. From a statistical point of view, the spectra of different stars can be represented as functional data. Therefore, a two-step procedure decomposing the spectra in a functional basis combined with a regression method of prediction is proposed. We also use a bootstrap methodology to build prediction intervals for the stellar parameters. A practical application is also provided to illustrate the numerical performance of our approach.

description: In a previous work, by extending the classical Quillen construction to the non-simply connected case, we have built a pair of adjoint functors, 'model' and 'realization', between the categories of simplicial sets and complete differential graded Lie algebras. This paper is a follow up of this work. We show that when X is a finite connected simplicial set, then the realization of the model of X is the disjoint union of the Bousfield-Kan completion of X with an external point. We also define a model category structure on the category of complete differential graded algebras making the two previous functors a Quillen pair, and we construct an explicit cylinder. In particular, these functors preserve homotopies and weak equivalences and therefore, this gives the basis for developing a Lie rational homotopy theory for all spaces.

description: The problem of mutual gravitational energy $W_{mut}$ for a system of two homogeneous prolate spheroids, whose symmetry axes are on the same line, is set and solved. The method of equigravitating elements is applied, where the external potentials of three-dimensional spheroids are represented by the potentials of one-dimensional inhomogeneous focal rods. The solution of the problem is reduced to the integration of the potential of one rod over the segment of the second rod. As a result, the expression $W_{mut}$ for two prolate spheroids can be obtained in a finite analytic form through elementary functions. The force of attraction between the spheroids is found. The function $W_{mut}$ is also represented by a power series in eccentricity of the spheroids. Possible applications of the obtained results are discussed.

description: We point out that, for Dirac neutrinos, in addition to the standard thermal cosmic neutrino background (C$ν$B) there could also exist a non-thermal neutrino background with comparable number density. As the right-handed components are essentially decoupled from the thermal bath of standard model particles, relic neutrinos with a non-thermal distribution may exist until today. The relic density of the non-thermal (nt) background can be constrained by the usual observational bounds on the effective number of massless degrees of freedom $N_\mathrm{eff}$, and can be as large as $n_{ν_{\mathrm{nt}}}\lesssim 0.5\,n_γ$. In particular, $N_\mathrm{eff}$ can be larger than 3.046 in the absence of any exotic states. Non-thermal relic neutrinos constitute an irreducible contribution to the detection of the C$ν$B, and, hence, may be discovered by future experiments such as PTOLEMY. We also present a scenario of chaotic inflation in which a non-thermal background can naturally be generated by inflationary preheating. The non-thermal relic neutrinos, thus, may constitute a novel window into the very early universe.

Electronic properties of transition metal atoms on Cu$_2$N/Cu(100)

description: We study the nature of spin excitations of individual transition metal atoms (Ti, V, Cr, Mn, Fe, Co and Ni) deposited on a Cu$_2$N/Cu(100) surface using both spin-polarized density functional theory (DFT) and exact diagonalization of an Anderson model derived from DFT. We use DFT to compare the structural, electronic and magnetic properties of different transition metal adatoms on the surface. We find that the average occupation of the transition metal d shell, main contributor to the magnetic moment, is not quantized, in contrast with the quantized spin in the model Hamiltonians that successfully describe spin excitations in this system. In order to reconcile these two pictures, we build a multi-orbital Anderson Hamiltonian for the d shell of the transition metal hybridized with the p orbitals of the adjacent Nitrogen atoms, by means of maximally localized Wannier function representation of the DFT Hamiltonian. The exact solutions of this model have quantized total spin, without quantized charge at the d shell. We propose that the quantized spin of the models actually belongs to many-body states with two different charge configurations in the d shell, hybridized with the p orbital of the adjacent Nitrogen atoms. This scenario implies that the measured spin excitations are not fully localized at the transition metal.

description: Book clubs, a staple of library programming, have low participation from men. This study amalgamates literature on contemporary book clubs, the reading habits of men and gendered communication theory to explore the reasons why book clubs are so unappealing to males. The findings suggest that changing book selection, new settings and the use of technology may be ways to make reading groups more compatible with male interests.

description: In this study the theory of term relevance weighting and circulation analysis were combined to investigate the relationship between specific dissertation descriptors and document use. The dissertation features examined included the major advisor for the research, the doctoral program university, the subject headings obtained from catalog records, and document requesters. Comparisons were made between descriptor relevance weights, assigned on the basis of item use or nonuse, and use of other dissertations characterized by these descriptors. Correlation coefficients were computed for these comparisons and the relationship between the weights of matching descriptors appearing in different samples. Requester descriptors were found to be the most reliable features for discriminating between item use and nonuse.

description: In this work we explore the possibility that the motion of the deuterium ions emitted from Coulomb cluster explosions is chaotic enough to resemble thermalization. We analyze the process of nuclear fusion reactions driven by laser-cluster interactions in experiments conducted at the Texas Petawatt laser facility using a mixture of D2+3He and CD4+3He cluster targets. When clusters explode by Coulomb repulsion, the emission of the energetic ions is nearly isotropic. In the framework of cluster Coulomb explosions, we analyze the energy distributions of the ions using a Maxwell- Boltzmann (MB) distribution, a shifted MB distribution (sMB) and the energy distribution derived from a log-normal (LN) size distribution of clusters. We show that the first two distributions reproduce well the experimentally measured ion energy distributions and the number of fusions from d-d and d-3He reactions. The LN distribution is a good representation of the ion kinetic energy distribution well up to high momenta where the noise becomes dominant, but overestimates both the neutron and the proton yields. If the parameters of the LN distributions are chosen to reproduce the fusion yields correctly, the experimentally measured high energy ion spectrum is not well represented. We conclude that the ion kinetic energy distribution is highly chaotic and practically not distinguishable from a thermalized one.

description: In a recent paper, Caron and Fox suggest a probabilistic model for sparse graphs which are exchangeable when associating each vertex with a time parameter in $\mathbb{R}_+$. Here we show that by generalizing the classical definition of graphons as functions over probability spaces to functions over $σ$-finite measure spaces, we can model a large family of exchangeable graphs, including the Caron-Fox graphs and the traditional exchangeable dense graphs as special cases. Explicitly, modelling the underlying space of features by a $σ$-finite measure space $(S,\mathcal{S},μ)$ and the connection probabilities by an integrable function $W\colon S\times S\to [0,1]$, we construct a random family $(G_t)_{t\geq 0}$ of growing graphs such that the vertices of $G_t$ are given by a Poisson point process on $S$ with intensity $tμ$, with two points $x,y$ of the point process connected with probability $W(x,y)$. We call such a random family a graphon process. We prove that a graphon process has convergent subgraph frequencies (with possibly infinite limits) and that, in the natural extension of the cut metric to our setting, the sequence converges to the generating graphon. We also show that the underlying graphon is identifiable only as an equivalence class over graphons with cut distance zero. More generally, we study metric convergence for arbitrary (not necessarily random) sequences of graphs, and show that a sequence of graphs has a convergent subsequence if and only if it has a subsequence satisfying a property we call uniform regularity of tails. Finally, we prove that every graphon is equivalent to a graphon on $\mathbb{R}_+$ equipped with Lebesgue measure.

Cooperative acquisition of archival materials

description: A contributory archive is one in which individual users may interact with materials through activities like commenting, tagging and sharing, but more importantly they may add content to the collection through uploading items like photos or videos and adding stories and text. This paper examines the community-led contributory archives listed at the website for the UK Community Archives and Heritage Group (www.communityarchives.org.uk), an umbrella organization that provides a central location for community archives, as a case study for expanding our knowledge of user participation in digital archives. This study examines user-generated content in digital community archives including annotations and contributions, the type and frequency of content created, and technical specifications as insight into amateur digital preservation of heritage materials. The information gleaned from this study can be used to assess the effectiveness of community-led projects as a possibility for cultural heritage centers to expand their mission in a participatory platform.

description: We study critical phenomena in the gravitational collapse of a radiation fluid. We perform numerical simulations in both spherical symmetry and axisymmetry, and observe critical scaling in both supercritical evolutions, which lead to the formation of a black hole, and subcritical evolutions, in which case the fluid disperses to infinity and leaves behind flat space. We identify the critical solution in spherically symmetric collapse, find evidence for its universality, and study the approach to this critical solution in the absence of spherical symmetry. For the cases that we consider, aspherical deviations from the spherically symmetric critical solution decay in damped oscillations in a manner that is consistent with the behavior found by Gundlach in perturbative calculations. Our simulations are performed with an unconstrained evolution code, implemented in spherical polar coordinates, and adopting "moving-puncture" coordinates.

description: This study describes a usability test of novice and expert users of archival finding aids. The test was conducted to determine whether the use of definitional phrasing, phrases used to explain and differentiate vague terms, in place of standard element titles would improve the navigability of archival finding aids by novice users.
Many studies have indicated that users, particularly novices, do not understand the terms used in archives and their finding aids to describe their materials. This is a serious issue for usability. This study proposed that definitional phrasing in place of standard element titles would improve the navigability of archival finding aids for novice users. The study did not find any demonstrable differences in navigation between the two versions of the finding aid, but recommends that further study be conducted to better understand both how users navigate finding aids and how improvements can be made to reflect these findings.

description: A recent focus in education on the importance of teaching social justice issues necessitates the creation of resources to support teachers and librarians in this work. This annotated bibliography recommends a selection of children's and young adult literature that features social action and social justice in the areas of human and civil rights, labor and community organizing, and the environment and animal welfare. This resource is not comprehensive, rather it highlights a selection of high-quality literature published in the last twenty years that through the genres of realistic fiction, historical fiction, narrative non-fiction and biography, provides models of social action for young people. Through identification with the literary role models in these works, children and teens can begin to understand the myriad forms that social justice can take and be empowered to make change in their own lives. This, then, is a collection of works for exploring the lives of historical change makers, imagining fictional ones, and identifying with the unsung heroes in our midst today.

 Index Fungorum number: —IF 554800; Facesoffungi number: —FoF 04770
 Etymology: —In reference to the aseptate conidia.
 Colonies on natural substrate, effuse, thin hairy, greenish-grey or brown. Mycelium partly superficial, partly immersed, consisting of branched, septate, smooth, thin-walled, subhyaline to pale hyphae. Stroma none. Setae and hyphopodia absent. Conidiophores 30–100 × 7–10 μm wide, macronematous, mononematous, scattered, solitary, cylindrical, robust at the base, erect, straight or slightly flexuous, unbranched, brown, fading towards the apex, septate, smooth, percurrently proliferating. Conidiogenous cells monophialidic, integrated, terminal, cylindrical, with a conspicuous collarette, subhyaline to pale brown. Conidia 9–12 × 6–9 μm, acrogenous, solitary or formed in slimy masses, obovoid to broadly obovoid, hyaline, unicellular, smooth, thin-walled, containing one guttula. Sexual morph: Undetermined.
 Known distribution:— Thailand.
 Culture characteristics: — On PDA, colony circular, reaching 11 mm in 5 days at 25°C, cream yellow and smooth in the center, white and slightly hairy on the outer edge, dry, edge entire.
 Notes: — Based on the combined gene analysis, Chloridium aseptatum has a close relationship with Chloridium gonytrichii F.A. Fernández & Huhndorf (= Melanopsammella gonytrichii) (100/99/1.00). Morphologically, C. gonytrichii has lateral conidiogenous cells, which is very different from C. aseptatum (Fernández et al. 2005). C. aseptatum is most similar to Chloridium xigazense Y.M. Wu & T.Y. Zhang in having flaring collarette and proliferating conidiogenous cells, and conidia produced singly, but conidia of the latter species is often adhering in chains and with a dark hilum at the subtruncate (Wu & Zhang 2013).

description: In this column, we will focus on the first vertical, Industrial AI. Today’s industrial machines are hyper-connected to the Industrial Internet of Things (IIoT) and have highly capable Edge computing. As a result, they constantly generate a wealth of diverse data that needs to be analyzed and consumed by other machines or human operators. This requires advanced descriptive, predictive, and prescriptive analytics, often combining physics-based and data driven models. Industrial AI covers the use of these models from production to manufacturing, quality control, operations, and maintenance. Given our space limitation, we will limit our discussion to Quality Control (QC) and Prognostics and Health Management (PHM) for maintenance.

description: We report on observations of giant pulses from the Crab pulsar performed simultaneously with the Parkes radio telescope and the incoherent combination of the Murchison Widefield Array (MWA) antenna tiles. The observations were performed over a duration of approximately one hour at a center frequency of 1382 MHz with 340 MHz bandwidth at Parkes, and at a center frequency of 193 MHz with 15 MHz bandwidth at the MWA. Our analysis has led to the detection of 55 giant pulses at the MWA and 2075 at Parkes above a threshold of 3.5$σ$ and 6.5$σ$ respectively. We detected 51$\%$ of the MWA giant pulses at the Parkes radio telescope, with spectral indices in the range of $-3.6>α> -4.9$ ($S_{\rm ν} \propto ν^α$). We present a Monte Carlo analysis supporting the conjecture that the giant pulse emission in the Crab is intrinsically broadband, the less than $100\%$ correlation being due to the relative sensitivities of the two instruments and the width of the spectral index distribution. Our observations are consistent with the hypothesis that the spectral index of giant pulses is drawn from normal distribution of standard deviation 0.6, but with a mean that displays an evolution with frequency from -3.00 at 1382 MHz, to -2.85 at 192 MHz.

description: This study examines the evolution of archival description at the Southern Historical Collection at the University of North Carolina at Chapel Hill. This study was conducted to analyze changes in the structure and contents of finding aids produced at the Southern Historical Collection from the 1930s through 2003, and to determine the degree to which these changes reflect the development of archival description at a national level. The Southern Historical Collection has updated its finding aids numerous times from the Works Progress Administration inventories used in the 1930s, to the EAD finding aids produced today. A description and comparison of these various finding aids not only illustrates the evolution of descriptive practices used at the Southern Historical Collection, but it also provides insight into the American archival profession's shift from adapting national guidelines on archival description to fit individual repository needs to the implementation of national descriptive standard.

description: We study a statistical mechanics model of two species of bosons with mutual statistics $θ=2π/n$ in (2+1) dimensions. This model realizes a fractionalized topological phase of bosons, which is a fractionalized version of the boson integer quantum Hall effect. The model can be studied with sign-free Monte Carlo simulations. We study the phase transitions between the fractionalized topological phase and a trivial insulator, and between different topological phases. We find that these transitions are continuous, and we measure their critical exponents.

description: We investigate the orbital origin of the Fano-Kondo line shapes measured in STM spectroscopy of magnetic adatoms on metal substrates. To this end we calculate the low-bias tunnel spectra of a Co adatom on the (001) and (111) Cu surfaces with our density functional theory-based ab initio transport scheme augmented by local correlations. In order to associate different $d$-orbitals with different Fano line shapes we only correlate individual $3d$-orbitals instead of the full Co $3d$-shell. We find that Kondo peaks arising in different $d$-levels indeed give rise to different Fano features in the conductance spectra. Hence the shape of measured Fano features allows to draw some conclusions about the orbital responsible for the Kondo resonance, although the actual shape is also influenced by temperature, effective interaction and charge fluctuations. Comparison with a simplified model shows that line shapes are mostly the result of interference between tunneling paths through the correlated $d$-orbital and the $sp$-type orbitals on the Co atom. Very importantly, the amplitudes of the Fano features vary strongly among orbitals, with the $3z^2$-orbital featuring by far the largest amplitude due to its strong direct coupling to the $s$-type conduction electrons.

Privacy
Information policy

description: Both privacy policies and end-user licensing agreements (EULAs) are ubiquitous in today's computing environment. Users are frequently prompted to agree to privacy policies and EULAs, and often do so without even looking at them. This is in seemingly direct contradiction to the documented concern consumers feel regarding the capture, storage and handling of their personal information by websites and mobile applications. This study explores why users may choose to disregard the single document that describes the level of privacy they can expect from websites and software companies. In particular, the interface, by which these policies are communicated to the user, is addressed, as previous research has noted its many deficiencies. The survey results indicate that users have a desire for increased control over their own personal information and that barriers, such as long blocks of legal text, should be addressed in order to increase policy notice readership on the web.

description: Contact-based vibrations play a critical role in the dynamics of granular materials. Significant insights into vibrational granular dynamics have been obtained with reduced-dimensional systems containing macroscale particles. We study contact-based vibrations of a two-dimensional monolayer of micron-sized spheres on a solid substrate. Measurements of the resonant attenuation of laser-generated surface acoustic waves reveal three collective vibrational modes involving both displacements and rotations of the microspheres. To identify the modes, we tune the interparticle stiffness, which shifts the frequency of the horizontal-rotational resonances while leaving the vertical resonance unaffected. From the measured contact resonance frequencies we determine both particle-substrate and interparticle contact stiffnesses and find that the former is an order of magnitude larger than the latter. This study paves the way for investigating complex contact-based dynamics of microgranular media, demonstrates a novel acoustic metamaterial, and yields a new approach to studying micro- to nanoscale contact mechanics in multiparticle networks.

description: We extracted ~2.8M nearly cloud-free 144x144 km^2 cutout images from the 2012-2020 Level-2 VIIRS Sea Surface Temperature (SST) dataset to quantitatively compare with MIT ocean general circulation model outputs, specifically the one year LCC4320 1/48 deg global-ocean simulation starting on November 17, 2011, matched in geography and day-of-year to VIIRS observations. We analyzed these cutouts using an unsupervised probabilistic autoencoder (PAE) to learn the SST structure on ~10-to-80 km scales (submesoscale-to-mesoscale). A key finding is that, in general, the LLC4320 simulation accurately reproduces the observed SST patterns, both globally and regionally. Global structure distribution medians match within 2 sigma for 65% of the ocean, despite a modest, latitude-dependent offset. Regionally, model outputs mimic mesoscale SST pattern variations in VIIRS data revealed by PAE, including subtle features influenced by bathymetry variations. There are however some areas showing significant differences in the distribution of SST patterns: (1) near western boundary currents' separation from the continental margin, (2) in the ACC, particularly in the eastern half of the Indian Ocean, and (3) in an equatorial band equatorward of 15 deg. The discrepancy in (1) results from premature separation of simulated western boundary currents. In (2), the Southern Indian Ocean, the model output predicts more structure than observed, possibly due to mixed layer misrepresentation or energy dissipation and stirring inaccuracies in the simulation. The differences in (3), the equatorial band, may also stem from model errors, potentially arising from the simulation's shortness or insufficient high-frequency/wavenumber atmospheric forcing. While the exact causes of these model-data differences remain uncertain, such comparisons are expected to guide future developments in high-resolution global-ocean simulations.

description: Automatic speaker naming is the problem of localizing as well as identifying each speaking character in a TV/movie/live show video. This is a challenging problem mainly attributes to its multimodal nature, namely face cue alone is insufficient to achieve good performance. Previous multimodal approaches to this problem usually process the data of different modalities individually and merge them using handcrafted heuristics. Such approaches work well for simple scenes, but fail to achieve high performance for speakers with large appearance variations. In this paper, we propose a novel convolutional neural networks (CNN) based learning framework to automatically learn the fusion function of both face and audio cues. We show that without using face tracking, facial landmark localization or subtitle/transcript, our system with robust multimodal feature extraction is able to achieve state-of-the-art speaker naming performance evaluated on two diverse TV series. The dataset and implementation of our algorithm are publicly available online.

description: This study examines serials title changes in scientific, social science, and humanities serials published in the United States and Canada. The investigator compared the presence and characteristics of title changes in a sample of 632 serial publications from the disciplines of anthropology, psychology, biology, physics, and literature and linguistics. Using data in the WorldCat records for these publications, comparisons were made for the characteristics of title change histories, including life span, rate of title change, and type of title change. Results were compared with those of previous serial title change studies. Findings are consistent with earlier studies, showing that scientific publications were most likely to have a history of title changes, while humanities serials were the least likely to change title. Scientific serials were found to have a higher frequency of title changes due to changes in scope. In the context of recent changes to cataloguing rules, the implications of these results are discussed.

description: This project sought affirmation of earlier findings of online disease-specific support groups. Support groups for Alzheimers, Breast Cancer, Esophageal Cancer, and Huntington's disease were studied. Literature suggests and this study agrees that group users are usually white, affluent, well-educated, and computer-savvy. The groups offer empathy, experiential knowledge, information, emotional nurturing, and a sense of control over disease. They are preferred over other support options. Altruistic behaviors are prevalent in groups - benefiting both giver and receiver. There is misinformation exchanged but it is quickly corrected. These groups improve the patient-physician relationship, fostering a team approach to disease, whereby patients receive a good education first, making more efficient use of their physician's limited time. However, most physicians do not suggest this alternative to patients. The project also investigated perceptions of privacy risk and whether real names are used in messages that may be archived and later retrieved from a personal computer.
