Library orientation

description: This paper discusses the need for and presents a model of web-accessible instruction and orientation resources to support users of archives and manuscript collections. Traditional archives orientation and user education practices, as well as web-based library instruction techniques, are reviewed to create a framework of types of information that should be provided and types of resources that best provide this information. A sample of thirty special collections departments at large research institutions are examined in depth using this framework to discover what user education resources are being implemented in the field. Applying the evaluation framework and findings, a model for web-based archives user education resources is offered, featuring content on archival orientation, intellectual access, physical access, and utilization.

description: Heat tolerance has emerged as a key trait in the tomato breeding pipeline. Previous research identified SNPs associated with reproductive traits under heat stress conditions, such as days to flowering (DTF) and fruit number. In this study, we developed Kompetitive Allele Specific PCR (KASP) markers based on these SNPs and validated the association of the DTF2 marker with the days to flowering trait. However, the fruit number markers Fruit1 and Fruit3 did not show a significant association with the fruit number trait.

description: The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated into planets. The majority of protoplanetary disks are born in clusters and, as a result, are exposed to external FUV radiation. These FUV photons potentially affect the disk's evolution, chemical composition, and line excitation. We present the first detection of the [CI]609um fine-structure line of neutral carbon (CI), achieved with ALMA, toward one of these disks, d203-506, in the Orion Nebula Cluster. We also report the detection of CI forbidden and permitted lines (from electronically excited states up to 10 eV) observed with JWST in the IR. These lines trace the irradiated outer disk and photo-evaporative wind. Contrary to the common belief that these IR lines are C+ recombination lines, we find that they are dominated by FUV-pumping of CI followed by fluorescence cascades. They trace the transition from atomic to molecular gas, and their intensities scale with G0. The lack of outstanding IR OI fluorescent emission, however, implies a sharper attenuation of external FUV radiation with E > 12 eV (~Lyman-beta). This is related to a lower effective FUV dust absorption cross section compared to that of interstellar grains, implying a more prominent role for FUV shielding by the CI photoionization continuum. The [CI]609um intensity is proportional to N(CI) and can be used to infer x_C. We derive x_C ~ 1.4E-4. This implies that there is no major depletion of volatile carbon compared to x_C measured in the natal cloud, hinting at a young disk. We also show that external FUV radiation impacts the outer disk and wind by vertically shifting the water freeze-out depth, which results in less efficient grain growth and settling. This shift leads to nearly solar gas-phase C/O abundance ratios in these irradiated layers.

description: Josephson elements are cornerstones of cryogenic classical and quantum superconducting technology, owing to their nonlinearity. Two important types of Josephson elements are often considered distinct: the tunnel junction (superconductor-insulator-superconductor, SIS) and the Andreev weak link (superconductor-normal-superconductor, SNS) referring to any non-superconducting and non-insulating central region. SNS junctions and SIS junctions have appeared in related technological and fundamental science contexts over the last decade, such as in the design of protected qubit concepts. In this perspective article, we review correspondences between SISIS junctions and SNS junctions in limiting regimes, in which a single energy-phase relationship describes both systems. We show how this insight helps to connect recent bodies of theoretical and experimental work in both systems, and conclude by describing a few important differences.

description: This study describes a questionnaire survey of bookmobile staff across the United States via the Association of Bookmobile and Outreach Services (ABOS). The survey was conducted to determine if and in what ways do bookmobile librarians and staff perceive bookmobiles as important and relevant to contemporary bookmobile users and how do they perceive the bookmobile's role in fulfilling patron's informational, recreational, and educational needs? Their thoughts and opinions help to explain why bookmobiles exist and their role in the modern world.Forty-eight bookmobile staff persons from 22 states responded. From the survey, it is clear that they believe strongly in what they do. 75% expected to continue to increase their services in the next 5 years due to increasing needs of seniors, preschoolers, school children, and communities. A growing need was seen for more bookmobiles, more specialized bookmobiles for specific populations, more technology and more staff to serve more people.

description: This study seeks to examine how North Carolina public librarians use book lists. Literature explains the importance of using book lists as a form of readers' advisory, but there are many book list formats in addition to ways for creating, promoting, and using lists. In order to find out how North Carolina librarians utilize book lists, 204 emails were successfully sent using a youth services directory inviting librarians to participate in an online survey. Results showed that while 93% of libraries use book lists, there are differing ways of creating, promoting, and using book lists. Formats also differed, although having lists in full pages was the most popular option. When book lists are available in both print and on the Web, print is overwhelmingly preferred. Book lists compiled by grade, age, and awards were the most popular lists. Suggestions are included for further research regarding patrons' thoughts on book lists.

Subjects: Law librarians--Job analysis

description: This research project examines job requirements advertised in the Washington Post from 1991 to 1999. Through the unobtrusive research method of content analysis, 146 advertisements were collected. After the postings were examined, a data collection sheet was created, and a list of variables developed. The headings of education, experience, skills, database familiarity and knowledge were examined. These advertisements reflect the needs and requirements of employers over the past decade. As such, these findings are indicative of the changing requirements and responsibilities of the law firm librarian. Changes in the legal market make it essential for law firm librarians to proactively respond to change and provide competitive legal services. More push-technologies, online tools,  and interpersonal skills are needed to meet user needs. The findings of this study indicates that the requirements for law firm library jobs reflect the changing functions of the law library.

description: This study is a content analysis of nine public library web pages for children as provided on the home page of the Association of Library Service to Children (ALSC).  The primary goal of this study is to determine the purpose of public library web pages for children as manifested by the content of their sites.  Seven purposes were proposed: (1) as a reference tool for children, (2) as a research tool for children, (3) as an entertainment tool for children, (4) as a public relations tool, (5) as a tool for the encouragement of reading, (6) as an instructional tool, and (7) as an information tool for parents and adults working with children.  On April 8 and 9, 2000, the library web sites were analyzed by using content criteria synthesized from information and library science literature and criteria established by the researcher for each of the proposed seven purposes.  Study results show the purpose of the public library web pages for children primarily as a tool for the encouragement of reading, followed closely by the library web site as a reference tool, and then as a research tool.  The library web sites also served as a public relations and instructional tool, though not as predominantly as the first three purposes.  The purposes for which the library web sites appeared to be the least evident were as an entertainment tool and as an information tool for parents and adults.

description: Objective: To identify rule sets based on administrative data to detect the IOM priority  conditions (Persistent Asthma, Diabetes, Heart Failure, COPD, Hypertension, MI, Stroke,  & Hyperlipidemia) as well as obesity and depression, and also to evaluate each rule set's  applicability to clinical decision support (CDS)  Design: Administrative Code based rule sets generated by an iterative process and  evaluated by direct comparison with a chart review based gold standard.  Data sources: Medicaid claims data from North Carolina Health Information Exchange  compared with electronic medical records from the Duke University Health System.  Results: 10 diseases were included in our study. Of these 10, only 2 diseases,  hypertension (HTN) and diabetes mellitus (DM) produced adequate rule sets for clinical  decision support. HTN had PPVs ranging from 0.89 to 0.94, and DM had PPVs ranging  from 0.91 to 0.94. The rule sets for the other diseases all had PPVs less then 0.90, and  were thus not considered to be useful for clinical decision support. Because not everyone  using disease detection algorithms has a CDS focus, we have included the performance of  all our generated rule-sets in tabular format.  Conclusions: Several factors were closely correlated with a rule set's ability to accurately  detect the presence of a particular disease. Perhaps the greatest of these factors was the  granularity of the underlying code system. For the 2 diseases which had very specific  ICD codes (i.e. HTN and DM), a simple and accurate rule set was created.

 Introduction: Cognitive impairment is among the core features of schizophrenia. In a healthy population, the cognitive deficit is often linked with cannabis abuse, and although the same would be expected in patients with schizophrenia, research has presented contradictory results. Methods: Participants were patients with first-episode schizophrenia (FES) spectrum disorder who had been lifetime cannabis users (N= 30), FES non-users (N= 53) as well as healthy controls (HC) also divided into cannabis users (N=20) and non-users (N= 49). All participants underwent an extensive neurocognitive assessment and filled in a cannabis questionnaire, which allowed for a comparison of the four groups on cognitive functioning. Results: FES patients using cannabis showed less impaired cognitive functioning with the most prominent difference in visual memory compared to FES non-users. However, they differed neither in the clinical assessment of general psychopathology, positive and negative symptoms, nor in medication from the patient’snon-users. A comparison of the HC who used cannabis, and those who did not, revealed no sizeable differences in cognitive performance between the groups. Conclusions: The results delivered supporting evidence for the trend of superior neurocognitive performance in FES patients with a lifetime history of cannabis use compared to non-using patients.

description: Literary sequels, retellings, and adaptations of Jane Austen's six original novels have  proliferated in the past 15 years, entering a wide array of genres and historical periods.  While these novels have been studied in some detail, an empirical study of Jane Austen  sequels and literary adaptations has yet to be performed. This study uses content analysis  in order to determine and examine a number of key qualities that elucidate character, plot  and language in ten Pride and Prejudice sequels, retellings and adaptations in order to  determine how closely these sequels and adaptations align themselves with Austen's  original. In doing so, it was discovered that, generally, adaptations tend to align  themselves more closely with Austen's original in terms of plot and character description,  while sequels and adaptations are less likely to depend on the original for character and  plot inspiration.

description: We have obtained IFU spectra of 75 SN Ia host galaxies from the Foundation Supernova survey to search for correlations between the properties of individual galaxies and SN Hubble residuals. After standard corrections for light-curve width and SN colour have been applied, we find correlations between Hubble residuals and the equivalent width of the [O II] $λλ$ 3727, 3729 doublet (2.3$σ$), an indicator of the specific star formation rate (sSFR). When splitting our sample by SN colour, we find no colour dependence impacting the correlation between EW[O II] and Hubble residual. However, when splitting by colour, we reveal a correlation between the Hubble residuals of blue SNe Ia and the Balmer decrement (2.2$σ$), an indicator of dust attenuation. These correlations remain after applying a mass-step correction, suggesting that the mass-step correction does not fully account for the limitations of the colour correction used to standardise SNe Ia. Rather than a mass correction, we apply a correction to SNe from star forming galaxies based on their measurable EW[O II]. We find that this correction also removes the host galaxy mass step, while also greatly reducing the significance of the correlation with the Balmer decrement for blue SNe Ia. We find that correcting for EW[O II], in addition to or in place of the mass-step, may further reduce the scatter in the Hubble diagram.

description: This research reports on a Web survey of visual resource experts. The research uses the data supplied by the experts to discuss if content-and concept-based image indexing and retrieval approaches may be improved by examining features relevant to both. Image descriptions were gathered from image professionals via a Web survey. The descriptions were analyzed to test whether color images evoke a denser textual description than grayscale images, and whether there is any significant variation in the words used to describe them. Analyses of data resulting from the survey of image description indicate that image professionals describe images with high-level concepts rather than low-level features, and that color does not affect the number or type of words used in their descriptions. This work may prompt future research with other building blocks of the systems in order to better integrate the research done by computer and library scientists in this area.

description: We introduce and study equivariant Hilbert series of ideals in polynomial rings in countably many variables that are invariant under a suitable action of a symmetric group or the monoid $Inc(\mathbb{N})$ of strictly increasing functions. Our first main result states that these series are rational functions in two variables. A key is to introduce also suitable submonoids of $Inc(\mathbb{N})$ and to compare invariant filtrations induced by their actions. Extending a result by Hillar and Sullivant, we show that any ideal that is invariant under these submonoids admits a Gröbner basis consisting of finitely many orbits. As our second main result we prove that the Krull dimension and multiplicity of ideals in an invariant filtration grow eventually linearly and exponentially, respectively, and we determine the terms that dominate this growth.

description: Legal citation indexes, known as citators, record and display information about the later-citing history and treatment of a dispositive legal document, usually a judicially published opinion, or "case." Presently, citators are digital tools integrated into large Web-based legal research platforms. This paper analyzes the accuracy with which descriptions of subsequent negative treatment are applied by a citator that employs a hierarchical controlled vocabulary-Shepard's Citations (a LexisNexis product)-as opposed to one that does not-KeyCite (a Thomson Reuters product). A framework for assessment is proposed and employed. The study's results suggest that a system making use of a hierarchical controlled vocabulary does apply descriptions of subsequent negative treatment in a marginally more accurate way. A discussion of the citator's place in legal research follows, including the suggestion that legal research instructors and researchers themselves, namely lawyers, should reconceptualize the role citators occupy in the research process.

description: We extend Babinet's relations, which are originally derived for transmissive metasurfaces, to reflective metasurfaces embedding planar metallic structures in a substrate containing a reflection mirror. To verify the extended Babinet's relations, we investigate two types of reflective metasurfaces embedding self-complementary structures, which produce $π$-phase difference between two orthogonal linear polarizations under specific conditions required for the extended Babinet's relations. Both theoretical and experimental studies demonstrate a metasurface-based half-wave plate with a reflective metasurface including single self-complementary structures in the terahertz regions. In addition, we study a reflective metasurface with embedded self-complementary structures with phase gradient in reflection, and demonstrate simultaneous implementation of anomalous reflection and polarization conversion with high efficiency.

However, a pure correlation analysis is not sufficient to prove that stock market returns are influenced by such emotional factors since both stock market prices and collective sentiment may be driven by a third unmeasured factor. Controlling for factors that could influence the study by applying multivariate regression models is challenging given the complexity of stock market data. False assumptions about the linearity or non-linearity of the model and inaccuracies on model specification may result in misleading conclusions. In this work, we propose a novel framework for causal inference that does not require any assumption about the statistical relationships among the variables of the study and can effectively control a large number of factors. We apply our method in order to estimate the causal impact that information posted in social media may have on stock market returns of four big companies. Our results indicate that social media data not only correlate with stock market returns but also influence them.

description: We present the properties of two candidate massive ($M_\star\sim10^{11}M_\odot$) and dusty ($A_{\rm v}>2.5$ mag) galaxies at $z=5-7$ in the first 0.28 deg$^2$ of the COSMOS-Web survey. One object is spectroscopically confirmed at $z_{\rm spec}=5.051$, while the other has a robust $z_{\rm phot}=6.7\pm0.3$. Thanks to their extremely red colors ($F277W-F444W\sim1.7$ mag), these galaxies satisfy the nominal color-selection for the widely-studied ``little red dot" (LRD) population with the exception of their spatially-resolved morphologies. The morphology of our targets allows us to conclude that their red continuum is dominated by highly obscured stellar emission and not by reddened nuclear activity. Using a variety of SED-fitting tools and star formation histories, we estimate the stellar masses to be $\log(M_\star)=11.32^{+0.07}_{-0.15}$ $M_\odot$ and $\log(M_\star)=11.2^{+0.1}_{-0.2}$ $M_\odot$, respectively, with a red continuum emission dominated by a recent episode of star formation. We then compare their number density to the halo mass function to infer stellar baryon fractions of $ε_\star\sim0.25$ and $ε_\star\sim0.5$. Both are significantly higher than what is commonly observed in lower-z galaxies or more dust-obscured galaxies at similar redshifts. With very bright ultra-high-z Lyman-Break Galaxies and some non-AGN dominated LRDs, such ``extended" LRDs represent another population that may require very efficient star formation at early times.

description: It was shown that the divalent rare earth ions (La, Ce, Gd, Tb, Lu, and Y) in cubic sites in alkaline earth fluorides are unstable with respect to electron autodetachment since its d1(eg) ground state is located in the conduction band which is consistent with the general tendency of these ions in various compounds. The localization of doubly degenerate d1(eg) level in the conduction band creates a configuration instability around the divalent rare earth ion that leading to the formation of anion vacancy in the nearest neighborhood, as was reported in the previous paper [Journal of Physics and Chemistry of Solids 74 (2013) 530-534]. Thus, the formation of the stable divalent ions as La, Ce, Gd, Tb, Lu, and Y (PC+ centers) in CaF2 and SrF2 crystals during x-ray irradiation occurs via the formation of charged anion vacancies near divalent ions (Re2+va), which lower the ground state of the divalent ion relative to the conductivity band. Photochromic effect occurs under thermally or optically stimulated electron transition from the divalent rare earth ion to the neighboring anion vacancy and reverse under ultraviolet light irradiation.

description: The Orange County Historical Museum, located in Hillsborough, North Carolina, sought to find a method of digitizing selected maps from its collection in a format that could also be used to display the maps for exhibition purposes. The purpose of this Master's Project was to acquire digital surrogates of a small group of historical maps, geo-reference copies of these map images, and develop a digital humanities project that could be used as a research tool and augment the museum's online presence. This process created files associated with each map that can be used to digitally layer the maps in software based on Geographic Information System (GIS) principles, such as Google Maps and the ArcGIS suite. This paper discusses relevant digital humanities theories and documents the design strategies and processes of the project.
A Model For Intergalactic Filaments and Galaxy Formation During the First Gigayear

description: We propose a physically based, analytic model for intergalactic filaments during the first gigayear of the universe. The structure of a filament is based upon a gravitationally bound, isothermal cylinder of gas. The model successfully predicts for a cosmological simulation the total mass per unit length of a filament (dark matter plus gas) based solely upon the sound speed of the gas component, contrary to the expectation for collisionless dark matter aggregation. It argues that the gas, through its hydrodynamic properties, plays a key role in filament structure rather than being a passive passenger in a preformed dark matter potential. The dark matter of a galaxy follows the classic equation of collapse of a spherically symmetric overdensity in an expanding universe. In contrast, the gas usually collapses more slowly. The relative rates of collapse of these two components for individual galaxies can explain the varying baryon deficits of the galaxies under the assumption that matter moves along a single filament passing through the galaxy centre, rather than by spherical accretion. The difference in behaviour of the dark matter and gas can be simply and plausibly related to the model. The range of galaxies studied includes that of the so-called "too big to fail" galaxies, which are thought to be problematic for the standard Lambda-CDM model of the universe. The isothermal-cylinder model suggests a simple explanation for why these galaxies are, unaccountably, missing from the night sky.

description: Driven by a sufficiently powerful pump laser, a cavity optomechanical system will stabilize in coupled oscillations of its cavity field and mechanical resonator. It was assumed that the oscillation will be continuously magnified upon enhancing the driving laser further. However, based on the nonlinear dynamics of the system, we find that the dynamical behaviors of the system are much more complex than this intuitive picture, especially when it is operated near the blue detuning point by the mechanical resonator's intrinsic frequency. There exists an anomalous stabilization: depending on its intrinsic damping rate and the pump power, the mechanical resonator will metastably stay on one orbit of oscillation after another until it completely stabilizes on the final orbit it can reach. These orbits are consistent with the locked ones with almost fixed oscillation amplitudes, which are realized after the pump power becomes still higher. The oscillatory cavity field is seen to adjust its sidebands following the mechanical frequency shift due to optical spring effect, so that it always drives the mechanical resonator to near those locked orbits once the pump power is over a threshold. In the regimes with such correlation between cavity field sidebands and mechanical oscillation, the system's dynamical attractors are confined on the locked orbits and chaotic motion is also excluded.

description: Museums are proven to significantly impact the economic well-being of their local communities.  The return on investment of museums in small communities includes increased direct and indirect spending, increased tourism and exposure for local businesses, and an increase in prestige of the town.  The purpose of this master's project is to analyze the practices and standards employed for the creation of the Saxapahaw History Museum and archive, and how the Saxapahaw History Museum will positively impact the local society both economically and culturally.  After discussing the current operating processes and goals of the museum, I attempt to determine the most applicable and cost-effective methods for the Museum to best preserve its collections and offer suggestions for modifying the current system into one which upholds the standards set forth by the American Museum Association.
