Job analysis

description: The study investigates qualifications employers seek in new employees with regards to the position of reference librarian and whether library and information science programs are offering courses that will help students interested in a career in reference librarianship meet employers' expectations and requirements.  The investigation is based on a content analysis of 58 job announcements for reference librarians and 60 course descriptions from library science programs.  The job announcements and library and information science programs were selected randomly from Northeast, South, Midwest and West regions across the United States using job announcements that were posted on the World Wide Web.  Course descriptions were selected using the online course catalog from school.  Over half (50%) of the job announcements listed excellent interpersonal skills as required for the job with over a third (33%) listing technological abilities/skills as the next most frequently mentioned qualification.  In contrast, only 21% of school course descriptions appeared to emphasize interpersonal skills in the course while collection development skills and technological abilities/skills were emphasized in 36% and 38% respectively of the courses.

description: This study examines the beginnings of regularly published reviews of children's books in columns and journals from the period of 1918 to 1929. The influence of the historical context on this development is considered. The first year or volume of children's book reviews in The Bookman (1918), New York Herald-Tribune Books (1924), The Horn Book (1924), Saturday Review of Literature (1927), and Library Journal (1929) are analyzed with regards to audience addressed, the reviewer's intention, format used, and inclusion of bibliographic and other commentary or material. In addition, individual reviews of the 1922 to 1930 Newbery Award winners are analyzed as to the descriptive, critical, and sociological elements they contained, length, and reviewer's attitude towards the book. Booklist is briefly considered in addition to the previous journals in this section. The early reviews are characterized by an interest in promotion of reading and owning quality children's books to a general audience of parents. These characteristics still influence the reviews being published today for library professionals.

description: The ATLAS collaboration (and also CMS) has recently reported an excess over Standard Model expectations for gauge boson pair production in the invariant mass region $1.8-2.2$ TeV. In the light of these results, we argue that such signal might be the first manifestation of the production and further decay of a heavy CP-even Higgs resulting from a type-I Two Higgs Doublet Model. We demonstrate that in the presence of colored vector-like fermions, its gluon fusion production cross-section is strongly enhanced, with the enhancement depending on the color representation of the new fermion states. Our findings show that barring the color triplet case, any QCD "exotic" representation can fit the ATLAS result in fairly large portions of the parameter space. We have found that if the diboson excess is confirmed and this mechanism is indeed responsible for it, then the LHC Run-2 should find: (i) a CP-odd scalar with mass below $\sim 2.3$ TeV, (ii) new colored states with masses below $\sim 2$ TeV, (iii) no statistically significant diboson events in the $W^\pm Z$ channel, (iv) events in the triboson channels $W^\pm W^\mp\,Z$ and $ZZZ$ with invariant mass amounting to the mass of the CP-odd scalar.

description: Vor dem Hintergrund der digitalen Transformation sind Finanzdienstleistungsunternehmen auf unterschiedlichen Ebenen zahlreichen Chancen sowie Herausforderungen ausgesetzt. Während der Einsatz neuer Technologien die Optimierung bestehender Geschäftsprozesse sowie das Angebot digitalisierter Finanzdienstleistungen ermöglicht, geht dies zugleich mit veränderten Arbeitsbedingungen innerhalb der Unternehmensorganisation einher. Darüber hinaus sind Finanzdienstleister dazu angehalten die sich ändernden Kundenerwartungen bei den bisherigen Geschäftsaktivitäten sowie bei der Produktentwicklung zu berücksichtigen. Das Ziel der vorliegenden kumulativen Dissertation ist es, bestehende Forschungsdesiderate hinsichtlich der Auswirkungen der digitalen Transformation auf den Finanzdienstleistungssektor, differenziert nach der Kunden- und Produktperspektive sowie der internen Unternehmensperspektive, vertiefend zu analysieren. Das Technology-Organization-Environment (TOE)-Framework von DePietro et al. (1990) wird dabei als theoretischer Rahmen zur Einordnung und Strukturierung der Forschungsmodule verwendet. Die Ergebnisse der acht Module zeigen, dass die Kundenbedürfnisse und –erwartungen im Finanzdienstleistungssektor verstärkt von der digitalen Transformation beeinflusst werden. Dies zeigt sich in der Beratungstätigkeit bspw. durch das Angebot neuer Kundenkanäle sowie der aus dem steigenden Wettbewerbsdruck resultierenden erhöhten Preistransparenz. Im Rahmen der Produktentwicklung sind zudem u. a. ESG-Risiken und Silent Cyber-Risiken zu beachten. Aus der Analyse der Auswirkungen der digitalen Transformation auf die Unternehmensorganisation geht hervor, dass über den Einsatz digitaler Innovationen innerhalb des Backoffice die Realisation von Effizienzgewinnen sowie das Entgegenwirken eines Personalmangels möglich ist. Darüber hinaus wird in den Modulen der Einfluss des Faktors Mensch auf die Cyber-Sicherheit hervorgehoben. Während dieser einerseits als „schwächstes Glied“ und potenzielles Angriffsziel im Sicherheitskonstrukt der Unternehmen dargestellt wird, ist andererseits das Potenzial der Beschäftigten zur Frühwarnung zu berücksichtigen.

description: For many catalogers, web sites that are pertinent to their users' needs are particularly challenging to catalog. While AACR2 has addressed the standards for cataloging electronic resources, including web sites, the structures and constantly changing information within web sites makes cataloging them problematic. This guide provides new catalogers who are not familiar with cataloging web sites with strategies for effective copy cataloging using the OCLC Connexion cataloging tool. Some of the topics explored are the development of the Internet, reasons for cataloging web sites, problems with cataloging web sites, and maintaining web addressing, using AACR2 rules or Dublin Core metadata schemes and the fields and code typically used in catalog records for web sites.

description: We carry out a detailed superspace analysis of the OPE of two N=2 stress-tensor multiplets. Knowledge of the multiplets appearing in the expansion, together with the two-dimensional chiral algebra description of N=2 SCFTs, imply an analytic bound on the central charge c. This bound is valid for any N=2 SCFT regardless of its matter content and flavor symmetries, and is saturated by the simplest Argyres-Douglas fixed point. We also present a partial conformal block analysis for the scalar superconformal primary of the multiplet.

description: We revisit the notion of intuitionistic equivalence and formal proof representations by adopting the view of formulas as exponential polynomials. After observing that most of the invertible proof rules of intuitionistic (minimal) propositional sequent calculi are formula (i.e. sequent) isomorphisms corresponding to the high-school identities, we show that one can obtain a more compact variant of a proof system, consisting of non-invertible proof rules only, and where the invertible proof rules have been replaced by a formula normalisation procedure. Moreover, for certain proof systems such as the G4ip sequent calculus of Vorob'ev, Hudelmaier, and Dyckhoff, it is even possible to see all of the non-invertible proof rules as strict inequalities between exponential polynomials; a careful combinatorial treatment is given in order to establish this fact. Finally, we extend the exponential polynomial analogy to the first-order quantifiers, showing that it gives rise to an intuitionistic hierarchy of formulas, resembling the classical arithmetical hierarchy, and the first one that classifies formulas while preserving isomorphism.

description: We consider the space of odd spinors on the circle, and a decomposition into spinors supported on either the top or on the bottom half of the circle. If an operator preserves this decomposition, and acts on the bottom half in the same way as a second operator acts on the top half, then the fusion of both operators is a third operator acting on the top half like the first, and on the bottom half like the second. Fusion restricts to the Banach-Lie group of restricted orthogonal operators, which supports a central extension of implementers on a Fock space. In this article, we construct a lift of fusion to this central extension. Our construction uses Tomita-Takesaki theory for the Clifford-von Neumann algebras of the decomposed space of spinors. Our motivation is to obtain an operator-algebraic model for the basic central extension of the loop group of the spin group, on which the fusion of implementers induces a fusion product in the sense considered in the context of transgression and string geometry. In upcoming work we will use this model to construct a fusion product on a spinor bundle on the loop space of a string manifold, completing a construction proposed by Stolz and Teichner.

description: We study in this work the near-field radiative heat transfer between two semi-infinite parallel planes of highly n-doped semiconductors. Using a nonlocal model of the dielectric permittivity, usually used for the case of metallic planes, we show that the radiative heat transfer coefficientsaturates as the separation distance is reduced for high doping concentration. These results replace the 1/d${}^2$ infinite divergence obtained in the local model case. Different features of the obtained results are shown to relate physically to the parameters of the materials, mainly the doping concentration and the plasmon frequency.

description: We present closed-form analytic solutions to non-secular Bloch-Redfield master equations for quantum dynamics of a V-type system driven by weak coupling to a thermal bath. We focus on noise-induced Fano coherences among the excited states induced by incoherent driving of the V-system initially in the ground state. For suddenly turned-on incoherent driving, the time evolution of the coherences is determined by the damping parameter $ζ=\frac{1}{2}(γ_1+γ_2)/Δ_p$, where $γ_i$ are the radiative decay rates of the excited levels $i=1,2$, and $Δ_p=\sqrt{Δ^2 + (1-p^2)γ_1γ_2}$ depends on the excited-state level splitting $Δ>0$ and the angle between the transition dipole moments in the energy basis. The coherences oscillate as a function of time in the underdamped limit ($ζ\gg1$), approach a long-lived quasi-steady state in the overdamped limit ($ζ\ll 1$), and display an intermediate behavior at critical damping ($ζ= 1$). The sudden incoherent turn-on generates a mixture of excited eigenstates $|e_1\rangle$ and $|e_2\rangle$ and their in-phase coherent superposition $|ϕ_+\rangle = \frac{1}{\sqrt{2\bar{r}}}(\sqrt{r_1} |e_1\rangle + \sqrt{r_2}|e_2\rangle)$, which is remarkably long-lived in the overdamped limit (where $r_1$ and $r_2$ are the incoherent pumping rates). Formation of this coherent superposition {\it enhances} the decay rate from the excited states to the ground state. In the strongly asymmetric V-system where the coupling strengths between the ground state and the excited states differ significantly, we identify additional asymptotic quasistationary coherences, which arise due to slow equilibration of one of the excited states. Finally, we demonstrate that noise-induced Fano coherences are maximized with respect to populations when $r_1=r_2$ and the transition dipole moments are fully aligned.

description: The purpose of the study was to determine the information needs of study abroad students and the extent to which academic libraries can fulfill those needs. Data were gathered using a web survey and semi-structured interviews of students who completed a study abroad program through the University of North Carolina at Chapel Hill. Respondents had a variety of information needs, consulted a wide range of sources, and encountered unique challenges to information seeking before, during and after they studied abroad.  The respondents reported that library materials covering travel and country information would be most helpful to them. The respondents also suggested that UNC-CH Libraries collaborate with the Study Abroad Office and that UNC-CH Libraries actively advertise the availability of resources and services for study abroad students through signage, the library web site and promotional materials.

description: Large public universities, like most organizations, are faced with the challenge of managing websites with thousands of pages and documents.  The importance of the web as a primary communication tool raises the stakes and makes this challenge even greater.  A discipline among web professionals known as content strategy promises to put order to content publishing and maintenance systems for more effective content.  This study aims to determine whether organizations within a large public university are actually adopting these techniques, and what results they might be realizing in terms of effectiveness and efficiency.  Through a literature review and analysis of the results of a survey sent to web communication professionals, several recommendations are made for improving organization websites and the systems that publish them.
High-order mixed finite elements for an energy-based model of the polarization process in ferroelectric materials

description: An energy-based model of the ferroelectric polarization process is presented in the current contribution. In an energy-based setting, dielectric displacement and strain (or displacement) are the primary independent unknowns. As an internal variable, the remanent polarization vector is chosen. The model is then governed by two constitutive functions: the free energy function and the dissipation function. Choices for both functions are given. As the dissipation function for rate-independent response is non-differentiable, it is proposed to regularize the problem. Then, a variational equation can be posed, which is subsequently discretized using conforming finite elements for each quantity. We point out which kind of continuity is needed for each field (displacement, dielectric displacement and remanent polarization) is necessary to obtain a conforming method, and provide corresponding finite elements. The elements are chosen such that Gauss' law of zero charges is satisfied exactly. The discretized variational equations are solved for all unknowns at once in a single Newton iteration. We present numerical examples gained in the open source software package Netgen/NGSolve.

description: Antiprotons are produced at CERN by colliding a 26 GeV/c proton beam with a fixed target made of a 3 mm diameter, 55 mm length iridium core. The inherent characteristics of antiproton production involve extremely high energy depositions inside the target when impacted by each primary proton beam, making it one of the most dynamically demanding among high energy solid targets in the world, with a rise temperature above 2000 °C after each pulse impact and successive dynamic pressure waves of the order of GPa's. An optimized redesign of the current target is foreseen for the next 20 years of operation. As a first step in the design procedure, this numerical study delves into the fundamental phenomena present in the target material core under proton pulse impact and subsequent pressure wave propagation by the use of hydrocodes. Three major phenomena have been identified, (i) the dominance of a high frequency radial wave which produces destructive compressive-to-tensile pressure response (ii) The existence of end-of-pulse tensile waves and its relevance on the overall response (iii) A reduction of 40% in tensile pressure could be obtained by the use of a high density tantalum cladding.

description: A bar-joint framework $(G,p)$ in $\mathbb{R}^d$ is rigid if the only edge-length preserving continuous motions of the vertices arise from isometries of $\mathbb{R}^d$. It is known that, when $(G,p)$ is generic, its rigidity depends only on the underlying graph $G$, and is determined by the rank of the edge set of $G$ in the generic $d$-dimensional rigidity matroid $\mathcal{R}_d$. Complete combinatorial descriptions of the rank function of this matroid are known when $d=1,2$, and imply that all circuits in $\mathcal{R}_d$ are generically rigid in $\mathbb{R}^d$ when $d=1,2$. Determining the rank function of $\mathcal{R}_d$ is a long standing open problem when $d\geq 3$, and the existence of non-rigid circuits in $\mathcal{R}_d$ for $d\geq 3$ is a major contributing factor to why this problem is so difficult. We begin a study of non-rigid circuits by characterising the non-rigid circuits in $\mathcal{R}_d$ which have at most $d+6$ vertices.

description: We are taught that user feedback should be collected and utilized throughout the system’s development lifecycle of any application, however, this is not always done in practice. This was the case for UNC’s official mobile application CarolinaGo. As project manager of CarolinaGo, I am not aware of any previous such internal attempts to have users evaluate the application. I decided this would be an excellent opportunity to apply my knowledge of usability studies with the goal of producing actionable recommendations for the improvement of the app. I recruited ten students as participants to complete this task-based think-aloud usability study which also included a System’s Usability Scale questionnaire and a post-task interview.  After analysis of their likes, dislikes, errors, frustrations, and suggestions I have come up with several recommendations that I think would greatly increase the usability and utility of the application.

description: Random walks (RW) of particles adsorbed in the internal walls of porous deposits produced by ballistic-type growth models are studied. The particles start at the external surface of the deposits and enter their pores, in order to simulate an external flux of a species towards a porous solid. For short times, the walker concentration decays as a stretched exponential of the depth z, but a crossover to long time normal diffusion is observed in most samples. The anomalous concentration profile remains at long times in very porous solids if the walker steps are restricted to nearest neighbors and is accompanied with subdiffusion features. These findings are correlated with a decay of the explored area with z. The study of RW of tracer particles left at the internal part of the solid rules out an interpretation by diffusion equations with position-dependent coefficients. A model of RW in a tube of decreasing cross section explains those results by showing long crossovers from an effective subdiffusion regime to an asymptotic normal diffusion. The crossover position and density are analytically calculated for a tube with area decreasing exponentially with z and show good agreement with numerical data. The anomalous decay of the concentration profile is interpreted as a templating effect of the tube shape on the total number of diffusing particles at each depth, while the volumetric concentration in the actually explored porous region may not have significant decay. These results may explain the anomalous diffusion of metal atoms in porous deposits observed in recent works. They also confirm the difficulty in interpreting experimental or computational data on anomalous transport reported in recent works, particularly if only the concentration profiles are measured.

description: Nested relations, built up from atomic types via product and set types, form a rich data model. Over the last decades the nested relational calculus, NRC, has emerged as a standard language for defining transformations on nested collections. NRC is a strongly-typed functional language which allows building up transformations using tupling and projections, a singleton-former, and a map operation that lifts transformations on tuples to transformations on sets. In this work we describe an alternative declarative method of describing transformations in logic. A formula with distinguished inputs and outputs gives an implicit definition if one can prove that for each input there is only one output that satisfies it. Our main result shows that one can synthesize transformations from proofs that a formula provides an implicit definition, where the proof is in an intuitionistic calculus that captures a natural style of reasoning about nested collections. Our polynomial time synthesis procedure is based on an analog of Craig's interpolation lemma, starting with a provable containment between terms representing nested collections and generating an NRC expression that interpolates between them. We further show that NRC expressions that implement an implicit definition can be found when there is a classical proof of functionality, not just when there is an intuitionistic one. That is, whenever a formula implicitly defines a transformation, there is an NRC expression that implements it.

It describes an online survey  distributed to University of North Carolina- Chapel Hill faculty members affiliated with  the College of Arts and Sciences. Results indicate the need for improved library-to-faculty  outreach to increase faculty awareness, use and value of services. This study  provides results intended to improve library service development and outreach efforts to  UNC-CH faculty members to encourage positive faculty-library relationships for  establishing and maintaining libraries as active and dynamic campus entities.

description: We study the rare semileptonic decays of $B$ mesons induced by $b \to s ν\barν$ as well as $b \to s l^+ l^-$ transitions in the scalar leptoquark model where the leptoquarks transform as $(3,2,7/6)$ and $(3,2,1/6)$ under the standard model gauge group. The leptoquark parameter space is constrained using the most recent experimental results on ${\rm Br}(B_s \rightarrow μ^+ μ^-)$ and ${\rm Br}(B_d \to X_s μ^+ μ^-)$ processes. Considering only the baryon number conserving leptoquark interactions, we estimate the branching ratios for the exclusive $\bar{B} \rightarrow \bar{K}^{(*)} ν\barν$ and inclusive $B \rightarrow X_s ν\barν$ decay processes by using the constraint parameters. We also obtain the low recoil (large lepton invariant mass, i.e., $q^2 \sim m^2_b$) predictions for the angular distribution of $\bar B \rightarrow \bar{K} l^+ l^-$ process and several other observables including the flat term and lepton flavour non-universality factor in this model.

The Utilization and Impact of Clinical Dysmorphology on Racially Diverse Patients: A Scoping Review
Creators: name: Woo, Stephanie
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Medicine and Health Sciences

description: The practice of dysmorphology is a key aspect of clinical genetics and diagnosis of genetic conditions. Early and accurate diagnosis of such conditions can result in earlier treatment and better prognosis. Previous research has described the need for changes in this specialty as the majority of phenotypic images used in training center around individuals of European descent. Research has also shown that genetic conditions present differently depending on a person’s racial background. To investigate this topic, we are proposing a scoping review of published literature, which would summarize the literature and research that has been conducted, identify the impact of dysmorphology on racially diverse patients, and outline the current efforts that exist to counter this inequity.
Career Choice of Young Adult Librarians in a Public Setting: A Narrative Analysis of Motivations with Implications for Recruitment

description: This study examines the career motivations of young adult librarians working in public libraries. Qualitative interviews were conducted with three practicing young adult librarians whose life stories were written in narrative form and analyzed using the principles of Career Construction Theory. Comparisons across the life stories of the participants revealed that young adult librarians share many career motivations with librarians in other specializations. The research also identified career factors specific to young adult librarians, including a young age, fondness for young people, and influences from their personal adolescent experience. The implications of these factors in the recruitment and employment of young adult librarians are discussed.
"Critical for Teaching and Learning": The Role of School Media  Specialists in Implementing Common Core Standards for Reading Informational Texts

description: Informational texts have been historically underutilized in elementary classrooms. However, new Common Core Standards require an increased emphasis on informational texts across the curriculum. As leaders and instructional partners in their schools, school library media specialists (SLMSs) have a strategic opportunity to support teachers and students within this changing educational landscape. This study examined how SLMSs in elementary schools are responding to this opportunity by conducting a national survey regarding their attitudes, practices, and barriers. Media specialists held positive views regarding the new standards for Reading Informational Texts (CCSS-RIT) except its potential impact on test scores. They were highly engaged in many practices supporting student use of informational texts, though less so in promoting reading. The results may indicate that SLMSs are still adjusting to the new standards. Barriers such as fixed schedules, budget constraints, and inadequate staffing may also play a significant role in the extent of their engagement.

description: We explore in the present work the near-field radiative heat transfer between two semi-infinite parallel nonlocal dielectric planes by means of fluctuational electrodynamics. We use atheory for the nonlocal dielectric permittivityfunction proposed byHalevi and Fuchs. This theory has the advantage to includedifferent models performed in the literature. According to this theory, the nonlocal dielectric function is described by a Lorenz-Drude like single oscillator model, in which the spatial dispersion effects are represented by an additional term depending on the square of the total wavevector k. The theory takes into account the scattering of the electromagneticexcitation at the surface of the dielectric material, which leads to the need of additional boundary conditions in order to solve Maxwell's equations and treat the electromagnetic transmission problem. The additional boundary conditions appear as additional surface scattering parameters in the expressions of the surface impedances. It is shown that the nonlocal modeling deviates from the classical $1/d^2$ law in the nanometerrangeat distances still larger than the ones where quantum effects are expected to come into play.

description: In order to compile an exploratory case study of Goucher College's Athenaeum Library, this study utilizes documentation analysis, non-participant observation, and semistructured interviews. The Athenaeum challenges the traditional concept of an academic library by integrating non-library elements such as an auditorium, art gallery, and exercise equipment into its space and actively encouraging engaged student learning. The study evaluates this design in order to discover whether its additional non-library features have increased patron satisfaction, how such additions have impacted library staff, and whether this multifunctional design can help make a case for the academic library's  continued existence as a physical presence on college campuses. The results of this case study highlight both positive and negative aspects of the Athenaeum's design and propose the foundations of a modern model that can be emulated by college libraries looking to creatively renovate library space or undertake a building project in the future.
Suppression of type I migration by disk winds

description: Planets less massive than Saturn tend to rapidly migrate inward in protoplanetary disks. This is the so-called type I migration. Simulations attempting to reproduce the observed properties of exoplanets show that type I migration needs to be significantly reduced over a wide region of the disk for a long time. However, the mechanism capable of suppressing type I migration over a wide region has remained elusive. The recently found turbulence-driven disk winds offer new possibilities. We investigate the effects of disk winds on the disk profile and type I migration for a range of parameters that describe the strength of disk winds. We also examine the in situ formation of close-in super-Earths in disks that evolve through disk winds. The disk profile, which is regulated by viscous diffusion and disk winds, was derived by solving the diffusion equation. We carried out a number of simulations and plot here migration maps that indicate the type I migration rate. We also performed N-body simulations of the formation of close-in super-Earths from a population of planetesimals and planetary embryos. We define a key parameter, Kw, which determines the ratio of strengths between the viscous diffusion and disk winds. For a wide range of Kw, the type I migration rate is presented in migration maps. These maps show that type I migration is suppressed over the whole close-in region when the effects of disk winds are relatively strong (Kw < 100). From the results of N-body simulations, we see that type I migration is significantly slowed down assuming Kw = 40. We also show that the results of N-body simulations match statistical orbital distributions of close-in super-Earths.

On the structure of non-planar strong coupling corrections to correlators of BPS Wilson loops and chiral primary operators

description: Starting with some known localization (matrix model) representations for correlators involving 1/2 BPS circular Wilson loop $\cal W$ in ${\cal N}=4$ SYM theory we work out their $1/N$ expansions in the limit of large 't Hooft coupling $λ$. Motivated by a possibility of eventual matching to higher genus corrections in dual string theory we follow arXiv:2007.08512 and express the result in terms of the string coupling $g_{\rm s} \sim g^2_{\rm YM} \sim λ/N$ and string tension $T\sim \sqrt λ$. Keeping only the leading in $1/T$ term at each order in $g_{\rm s} $ we observe that while the expansion of $\langle {\cal W} \rangle$ is a series in $g^2_{\rm s} /T$, the correlator of the Wilson loop with chiral primary operators ${\cal O}_J $ has expansion in powers of $g^2_{\rm s}/T^2$. Like in the case of $\langle {\cal W} \rangle$ where these leading terms are known to resum into an exponential of a "one-handle" contribution $\sim g^2_{\rm s} /T$, the leading strong coupling terms in $\langle {\cal W}\, {\cal O}_J \rangle$ sum up to a simple square root function of $g^2_{\rm s}/T^2$. Analogous expansions in powers of $g^2_{\rm s}/T$ are found for correlators of several coincident Wilson loops and they again have a simple resummed form. We also find similar expansions for correlators of coincident 1/2 BPS Wilson loops in the ABJM theory.
