description: This study examines California public libraries' collections of adult nonfiction books on abortion and same-sex marriage to determine whether a relationship exists between a library's political environment and the diversity of opinions in its collection. A checklist of 20 titles was assembled for each topic, and these book was categorized as either "pro" "anti" or "neutral" on the subject. Library holdings were examined using the California Libraries Catalog, and the political climate of a library's community was determined using recent election results. The expected outcome that there would be less diversity of opinion in libraries serving communities at either end of the political spectrum was not supported due to a lack of measurable data. Libraries situated in politically liberal communities were most likely to own checklist titles, even when controlling for population size. Further research is needed to develop effective methods for measuring how different variables influence the collection development process.

description: This paper examines the connections between academic libraries that have created  collaborative learning commons spaces and their partner archives. Semi-structured  interviews were conducted with reference librarians and archivists from three large public  universities, examining the institutions' user services, policies, and assessment measures  and how they have adapted to changes in their users and their users' expectations. The  study showed that librarians at academic libraries had utilized more assessment measures  in order to implement and assess changes to their user services than the archivists at the  archives at the same academic institution. These assessment measures used by libraries  showed that the shift to a collaborative learning environment had been received positively  by users and staff. Archivists were unable to report if this shift had changed their own  users' expectations; however, they felt that user expectations would change, though they  were unsure what that meant for the future of their user services.

description: The one-loop long distance quantum corrections to the Newtonian potential imply tiny but observable effects in the restricted three-body problem of celestial mechanics, i.e., both at the Lagrangian points of stable equilibrium and at those of unstable equilibrium the Newtonian values of planetoid's coordinates are changed by a few millimetres in the Earth-Moon system. First, we find that the equations governing the position of both noncollinear and collinear quantum libration points are algebraic fifth degree and ninth degree equations, respectively. Second, we discuss the prospects to measure, with the help of laser ranging, the above departure from the equilateral triangle picture, which is a challenging task. On the other hand, a modern version of the planetoid is the solar sail, and much progress has been made, in recent years, on the displaced periodic orbits of solar sails at all libration points. By taking into account the quantum corrections to the Newtonian potential, displaced periodic orbits of the solar sail at libration points are again found to exist.

Does Maxwell’s hypothesis of air saturation near the surface of evaporating liquid hold at all spatial scales
Creators: name: Benilov, Eugene
Publisher: name: University of Limerick
Year: 2023
Subjects: classificationCode: 49
subject: Mathematical sciences

description: The classical model of evaporation of liquids hinges on Maxwell’s assumption that the air near the liquid’s surface is saturated. It allows one to find the evaporative flux without considering the interface separating liquid and air. Maxwell’s hypothesis is based on an implicit assumption that the vapour-emission capacity of the interface exceeds the throughput of air (i.e. its ability to pass the vapour on to infinity). If this is indeed so, then the air adjacent to the liquid would get quickly saturated, justifying Maxwell’s hypothesis. In the present paper, the so-called diffuse-interface model is used to account for the interfacial physics and thus derive a generalised version of Maxwell’s boundary condition for the near-interface vapour density. It is then applied to a spherical drop floating in air. It turns out that the vapour-emission capacity of the interface exceeds the throughput of air only if the drop’s radius is rd - 10 µm, but for rd ≈ 2 µm, the two are comparable. For rd - 1 µm, evaporation is interface-driven, and the resulting evaporation rate is noticeably smaller than that predicted by the classical model.
Perceptions and Knowledge of Privacy Risks in Mobile Apps

description: Consumers often have little knowledge about the extent of privacy risks taken when using mobile applications (apps) on their smartphones, and are unlikely to be informed by federal regulations or privacy certifications. A survey was distributed to smartphone users to determine their perceptions and knowledge of privacy risks in mobile apps, and if these perceptions vary in different contexts (i.e., a health app vs. flashlight app). This study found that people appear to see privacy in mobile apps as contingent and context-dependent. While smartphone users were found to have a good understanding of privacy risks, they considered user rating and price to be more important factors to consider than privacy when selecting a mobile app. Presentation, clarity, and context all influence people's decisions to install and use mobile apps. This study has important implications for how privacy permissions and ratings can be presented to best inform consumer decisions.

description: Measurements of the redshift-space galaxy clustering have been a prolific source of cosmological information in recent years. Accurate covariance estimates are an essential step for the validation of galaxy clustering models of the redshift-space two-point statistics. Usually, only a limited set of accurate N-body simulations is available. Thus, assessing the data covariance is not possible or only leads to a noisy estimate. Further, relying on simulated realisations of the survey data means that tests of the cosmology dependence of the covariance are expensive. With these points in mind, this work presents a simple theoretical model for the linear covariance of anisotropic galaxy clustering observations with synthetic catalogues. Considering the Legendre moments (`multipoles') of the two-point statistics and projections into wide bins of the line-of-sight parameter (`clustering wedges'), we describe the modelling of the covariance for these anisotropic clustering measurements for galaxy samples with a trivial geometry in the case of a Gaussian approximation of the clustering likelihood. As main result of this paper, we give the explicit formulae for Fourier and configuration space covariance matrices. To validate our model, we create synthetic HOD galaxy catalogues by populating the haloes of an ensemble of large-volume N-body simulations. Using linear and non-linear input power spectra, we find very good agreement between the model predictions and the measurements on the synthetic catalogues in the quasi-linear regime.

“Why Would She Want to Read About Such Horrible Things?”: The Appeal of War as a Reading Interest for Girls
Creators: name: O'Bryan, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Reading appeal research has historically identified war as a topic of reading interest that correlates strongly with gender. Boys are traditionally much more likely than girls to read books involving war, and many girls prefer to avoid the topic. At the same time, research has consistently found smaller but significant numbers of girls who choose to read in this subject area. Using qualitative analysis of in-depth, semi-structured interviews, this study explored the appeal factors at play for five 11- and 12-year-old children who identify as girls (four in whole, one in part) who enjoy reading about war.Traditional reading appeal factors that were sought by these readers included action-packed storylines, an attention-grabbing writing style, fast or intensifying pacing, courageous characters, and a dramatic, suspenseful tone. Learning about historical events played an important role for readers of historical fiction, while fantasy fans were drawn to the presence of strong female characters working alongside males in an adventurous storyline. Gender issues pervaded the discussion, revealing feelings of powerlessness and inequality. Several participants reported benefits that aligned with outcomes associated with bibliotherapy as well as closer connections to men in their lives. The results of this study can support librarians in providing gender-transformative readers’ advisory services and assist other researchers in understanding gender dynamics in the middle grade years.

Carrboro Branch Library

description: This paper takes an in-depth look at the Carrboro (North Carolina) Branch Library, which shares space and resources with the school media center for the McDougle Elementary and Middle Schools. This library has existed as a joint organization for nearly ten years; a case study of this library's functions and of the people who run the libraries provides insight into how to form a successful union. The public library participants in this study responded to a questionnaire, based on requirements discussed in library science literature, which examines various aspects of the creation and administration of this organization. The primary factor which appears to affect the success of this specific joint venture is the flexibility of the librarian and media specialists when working together.

description: This research project investigated the relationship between school-based management and resources allocated to elementary school library media centers. To determine the effects of school-based management, ten years of data collected by the Media Services Division of Wake County Public School System from 1994-2003 was analyzed. The data was divided into three periods for comparison: 1994-1996 pre school-based management, 1997-1999 intermediate period, 2000-2003 full school-based management implementation.  Analysis of the data revealed that the majority of school library media centers (SLMC) had received significant cuts in their book budget since the onset of school-based management. Significant relationships were found between books per students and circulation per student as well as book budget per student and circulation per student. North Carolina's ABC test scores showed a negative relationship with the average age of books in the SLMC. Average age of books also correlated with the percentage of free and reduced lunch students.

description: This paper documents the process of building Mapping Early NC Lebanese Households, a public digital humanities project that uses census data to map Lebanese immigrants in select North Carolina cities from 1900 to 1930. Built by the Digital Innovation Lab at the University of North Carolina at Chapel Hill, the project is an interactive digital component of Cedars in the Pines, a museum exhibit organized by the Khayrallah Program for Lebanese-American Studies at North Carolina State University. The project also represents an effort to develop generalizable workflows and processes for collaborative digital mapping projects. This paper argues for the importance of documenting and sharing the decisions, workflows, and processes behind digital humanities projects as a means of transparency. Finally, the paper suggests ways to extend the features of DH Press, the humanities data visualization toolkit used to build the project.

description: A relaxed primordial power spectrum (PPS) of scalar perturbations arising from inflation can impact the dark radiation constraints obtained from Cosmic Microwave Background and other cosmological measurements. If inflation produces a non-standard PPS for the initial fluctuations, a fully thermalized light sterile neutrino can be favoured by CMB observations, instead of being strongly disfavoured. In the case of a thermal axion, the constraints on the axion mass are relaxed when the PPS is different from the standard power law.

description: In the world of scholarly publishing ideals of open access have developed and thrived in a variety of fields and settings. There has been a wide variety of research published on the benefits and nature of open access, but this research has often overlooked the overlap between scholarly publishing and federal research. Federally authored works are considered works of government and considered in the public domain, but oftentimes the scholarly works of federal authors are copyrighted by private publishers and remain behind paywalls. The number of these works of government that exist behind private paywalls has not been documented and there is little research into the topic. This paper examines this phenomenon through citations gathered across major databases as well as through interviews with copy editors who work with these federally authored papers.

description: Azithromycin (AZM) is a macrolide-type antibiotic used to prevent and treat serious infections (mycobacteria or MAC) that significantly inhibit bacterial growth. Knowledge of the predominant conformation in solution is of fundamental importance for advancing our understanding of the intermolecular interactions of AZM with biological targets. We report an extensive density functional theory (DFT) study of plausible AZM structures in solution considering implicit and explicit solvent effects. The best match between the experimental and theoretical nuclear magnetic resonance (NMR) profiles was used to assign the preferred conformer in solution, which was supported by the thermodynamic analysis. Among the 15 distinct AZM structures, conformer M14, having a short intramolecular C6-OH … N H-bond, is predicted to be dominant in water and DMSO solutions. The results indicated that the X-ray structure backbone is mostly conserved in solution, showing that large flexible molecules with several possible conformations may assume a preferential spatial orientation in solution, which is the molecular structure that ultimately interacts with biological targets.

description: This paper traces the rich history of the punk subculture from its inception in England in 1976 through its arrival in America until today.  The paper was written as a way to guide librarians at public libraries toward understanding a misrepresented and misunderstood population that continues to exist in communities throughout the United States.  With an understanding of the punk subculture, librarians may see punks as an adolescent subculture, apart from their reputations fro delinquency and begin to offer services to attract punks into the library building.  As with any youth subcultural groups with a potential for delinquency, some precautions and planning are needed.  However, the benefit to society that may result from offering a safe haven to delinquent subculture with potential for participation and engagement, outweighs the potential risks.

description: This paper documents published sources related to autobiographies and oral  histories of baseball players, pitchers, and managers who performed the  preponderance of their professional career before the United States of America's  involvement with the Second World War. The paper separates the individual  autobiographies into three sections based upon the era in which the player is  most associated with: the Iron Age (1869-1902), the Silver Age (1903-1922), and  the Golden Age (1904-1941). Each section arranges the players alphabetically by  surname, and every player entry contains a photograph, brief biographical  information, a quotation from the autobiography, and lists of anecdotal works,  biographies, films, and museums correlating to the player, when available. The  fourth section of the paper concerns oral history (1869-1941), arranging the  monographs alphabetically, with each entry including information about the  players interviewed similar to the first three sections, but arranged by the  player's occurrence in the monograph.
Magnetohydrodynamic Model of Late Accretion onto a Protoplanetary Disk: Cloudlet Encounter Event

description: Recent observations suggest late accretion, which is generally nonaxisymmetric, onto protoplanetary disks. We investigated nonaxisymmetric late accretion considering the effects of magnetic fields. Our model assumes a cloudlet encounter event at a few hundred au scale, where a magnetized gas clump (cloudlet) encounters a protoplanetary disk. We studied how the cloudlet size and the magnetic field strength affect the rotational velocity profile in the disk after the cloudlet encounter. The results show that a magnetic field can either decelerate or accelerate the rotational motion of the cloudlet material, primarily depending on the relative size of the cloudlet to the disk thickness. When the cloudlet size is comparable to or smaller than the disk thickness, magnetic fields only decelerate the rotation of the colliding cloudlet material. However, if the cloudlet size is larger than the disk thickness, the colliding cloudlet material can be super-Keplerian as a result of magnetic acceleration. We found that the vertical velocity shear of the cloudlet produces a magnetic tension force that increases the rotational velocity. The acceleration mechanism operates when the initial plasma $β$ is $ β\lesssim 2\times 10^1 $. Our study shows that magnetic fields modify the properties of spirals formed by tidal effects. These findings may be important for interpreting observations of late accretion.

description: We explore the relevance of the color-flavor locking phase in the equation of state (EoS) built with the Field Correlator Method (FCM) for the description of the quark matter core of hybrid stars. For the hadronic phase, we use the microscopic Brueckner-Hartree-Fock (BHF) many-body theory, and its relativistic counterpart, i.e. the Dirac-Brueckner (DBHF). We find that the main features of the phase transition are directly related to the values of the quark-antiquark potential $V_1$, the gluon condensate $G_2$ and the color-flavor superconducting gap $Δ$. We confirm that the mapping between the FCM and the CSS (constant speed of sound) parameterization holds true even in the case of paired quark matter. The inclusion of hyperons in the hadronic phase and its effect on the mass-radius relation of hybrid stars is also investigated.

description: Individuals now have the ability to effectively access information such as images, audio and video over the Internet. However, it has been only recently that researchers have been able to dedicate themselves to establishing techniques for coping with the retrieval of these multidimensional non-textual documents. This work examines some of the current work in the field of video retrieval and attempts to point out the importance of user needs analysis in retrieving video online. This study, through nine end-user interviews, takes a first step in providing information that designers can use in developing video retrieval systems. The results clearly indicate that there is a large need for video in many fields, and that there are common themes in the user needs within particular disciplines. Participants in this study wanted to express their queries in words, but needed to view stills and video clips when reviewing the results of their searches.
Sampling of bosonic qubits
Creators: name: Tamma, Vincenzo
Publisher: name: arXiv
Year: 2015

subject: FOS: Physical sciences

description: The boson sampling problem has brought a lot of attention in the quantum information field because it is not efficiently solvable with a classical computer; nonetheless it can be implemented with linear optical interferometers with single-boson sources. Recently, we introduced a more general problem, the multi-boson correlation sampling problem, which allows us to take advantage of the multi-mode spectral distribution of the bosonic sources together with time-correlated measurements in order to achieve sampling not only over the output ports of the interferometer but also over the joint detection times. This problem was analyzed for both single-photon sources and thermal sources. In this work, we demonstrate that it is possible to use single qubit bosonic sources in order to sample not only over the described "space-time" degree of freedom but also over all the possible exponential number of multi-qubit output states.

description: We reconstructed the energy and the position of the shower maximum of air showers with energies $E \gtrsim 100 $PeV applying a method using radio measurements performed with Tunka-Rex. An event-to-event comparison to air-Cherenkov measurements of the same air showers with the Tunka-133 photomultiplier array confirms that the radio reconstruction works reliably. The Tunka-Rex reconstruction methods and absolute scales have been tuned on CoREAS simulations and yield energy and $X_{\mathrm{max}}$ values consistent with the Tunka-133 measurements. The results of two independent measurement seasons agree within statistical uncertainties, which gives additional confidence in the radio reconstruction. The energy precision of Tunka-Rex is comparable to the Tunka-133 precision of $15 %$, and exhibits a $20 %$ uncertainty on the absolute scale dominated by the amplitude calibration of the antennas. For $X_{\mathrm{max}}$, this is the first direct experimental correlation of radio measurements with a different, established method. At the moment, the $X_{\mathrm{max}}$ resolution of Tunka-Rex is approximately $40 $g/cm$^2$. This resolution can probably be improved by deploying additional antennas and by further development of the reconstruction methods, since the present analysis does not yet reveal any principle limitations.

description: A bounce universe model with a scale-invariant and stable spectrum of primordial density perturbations was constructed using a consistent truncation of the D-brane dynamics from Type IIB string theory. A coupling was introduced between the tachyon field and the adjoint Higgs field on the D3-branes to lock the tachyon at the top of its potential hill and to model the bounce process, which is known as the Coupled Scalar and Tachyon Bounce (CSTB) Universe. The CSTB model has been shown to be ghost free, and it fulfils the null energy condition; in addition, it can also solve the Big Bang cosmic singularity problem. In this paper we conduct an extensive follow-up study of the parameter space of the CSTB model. In particular we are interested in the parameter values that can produce a single bounce to arrive at a radiation-dominated universe. We further establish that the CSTB universe is a viable alternative to inflation, as it can naturally produce a sufficient number of e-foldings in the locked inflation epoch and in the post-bounce expansion to overcome the four fundamental limitations of the Big Bang cosmology, which are flatness, horizon, homogeneity and singularity, resulting in a universe of the current size.

Getting Undergrads into Archives: Educational Outreach Efforts of University Archives, Manuscript Departments, and Special Collections

description: This study presents the results of phone interviews conducted with representatives of twenty-three university archives, manuscript departments, and special collections at Doctoral/Research Universities-Intensive, as classified by the Carnegie Foundation for the Advancement of Teaching. The purpose of the study is to attempt to portray the current state of educational outreach to undergraduate students. With undergraduate students composing an increasing portion of their users, primary source material repositories at universities have the opportunity to become a more relevant part of student education, as well as increase their profile on campus. Yet, few formal studies have explored the strategies in use by university archives, manuscript departments, and special collections to reach and instruct undergraduate students. The study finds that educational outreach to undergraduate students is fairly successful but largely non-regularized. Formalizing strategies, where resources make it feasible, will help increase the relevance of primary source material collections on their campuses.

description: This study focuses on how libraries, archives, museums, and other cultural heritageinstitutions define and assess the success of online crowdsourcing projects. The researchwas conducted via a survey of twenty-two digital crowdsourcing projects ranging fromtranscription of digitized archival materials to wildlife documentation projects.The survey found that institutions had diverse reasons for undertaking crowdsourcingprojects and monitored project success through multiple assessment measures dependenton project goals. Survey respondents reported greater satisfaction with their projectoutcomes when they had identified at least one measurable goal prior to starting theproject. In general, survey respondents reported positive feelings about, and an interest infuture crowdsourcing projects as tools for description, community engagement, and userrecruitment.
Four-boson bound states from a functional renormalisation group

description: We use the functional renormalisation group to study the spectrum of three- and four-body states in bosonic systems around the unitary limit. Our effective action includes all energy-independent contact interactions in the four-atom sector and we introduce a running trimer field to eliminate couplings that involve the atom-atom-dimer channel. The results show qualitatively similar behaviour to those from exact approaches. The truncated action we use leads to overbinding of the two four-body states seen in those treatments. It also generates a third state, although only for a very narrow range of two-body scattering lengths.

Holomorphic Poisson Structures and its Cohomology on Nilmanifolds
Creators: name: Chen, Zhuo

Publisher: name: arXiv

Subjects: subject: Differential Geometry (math.DG)

description: The subject for investigation in this note is concerned with holomorphic Poisson structures on nilmanifolds with abelian complex structures. As a basic fact, we establish that on such manifolds, the Dolbeault cohomology with coefficients in holomorphic polyvector fields is isomorphic to the cohomology of invariant forms with coefficients in invariant polyvector fields. We then quickly identify the existence of invariant holomorphic Poisson structures. More important, the spectral sequence of the Poisson bi-complex associated to such holomorphic Poisson structure degenerates at $E_2$. We will also provide examples of holomorphic Poisson structures on such manifolds so that the related spectral sequence does not degenerate at $E_2$.
