description: Radio synchrotron emission is a powerful tool to study the strength and structure of magnetic fields in galaxies. Unpolarized synchrotron emission traces isotropic turbulent fields which are strongest in spiral arms and bars (20-30 μG) and in central starburst regions (50-100 μG). Such fields are dynamically important; they affect gas flows and drive gas inflows in central regions. -- Polarized emission traces ordered fields, which can be regular or anisotropic turbulent, where the latter originates from isotropic turbulent fields by the action of compression or shear. The strongest ordered fields (10-15 μG) are generally found in interarm regions. In galaxies with strong density waves, ordered fields are also observed at the inner edges of spiral arms. Ordered fields with spiral patterns exist in grand-design, barred and flocculent galaxies, and in central regions. Ordered fields in interacting galaxies have asymmetric distributions and are a tracer of past interactions between galaxies or with the intergalactic medium. In radio halos around edge-on galaxies, ordered magnetic fields with X-shaped patterns are observed. -- Faraday rotation measures of the diffuse polarized radio emission from galaxy disks reveal large-scale spiral patterns that can be described by the superposition of azimuthal modes; these are signatures of regular fields generated by mean-field dynamos. "Magnetic arms" between gaseous spiral arms may also be products of dynamo action, but need a stable spiral pattern to develop. Helically twisted field loops winding around spiral arms were found in two galaxies so far. Large-scale field reversals, like the one found in the Milky Way, could not yet be detected in external galaxies. -- The origin and evolution of cosmic magnetic fields will be studied with forthcoming radio telescopes like the Square Kilometre Array.

Subjects: Other Indigenous studies not elsewhere classified

description: During the Great Rebellion of 1857-58, Kolhan-Porahat region of Singhbhum district, dominated by the Ho Adivasis, witnessed a fresh spurt of witch-killings. On the study of Trial Parrs, the essay seeks to examine to what extent this incidence was impacted by the political situation and the indigenous belief system An attempt is also made to understand whether witch-hunt was the product of temporary impulse or it was meticulously planned and socially enacted. The essay deals with the British attempt to control crime through their legal and judicial machinery. The examination of Trial Papers reveals that by perpetrating witch-murder, the Hos were not only attempting to restore their old social practice, but at the same time this was their strategy at offering resistance to exotic system The above aspects have been elaborated under four broad sections. First section studies the political and cultural factors motivating witch-killing. The second seeks to explore how the crime was the product of deep-seated conspiracy prior to the commitment of murder- The third examines the process of trial throwing light on when and how the crime was detected, agencies involved in the trial, testimonies and the award of punishments. The last section argues how the practice of witch-murder may be comprehended as a form of indigenous counter-offensive to British rule.
Seeing lens imaging as a superposition of multiple views

description: In the conventional approach to lens imaging, rays are used to map object points to image points. However, many students have a need to think of the image as a whole. To answer this need, lens imaging is reinterpreted as a superposition of sharp images from different viewpoints. These so-called elemental images are uncovered by covering the lens with a pinhole array. Rays are introduced to connect elemental images. Lens ray diagrams are constructed based on bundles of elemental images. The conventional construction method is included as a special case. The proposed approach proceeds from concrete images to abstract rays.

Adiabatic Mass Loss in Binary Stars. II. From Zero-Age Main Sequence to the Base of the Giant Branch

description: In the limit of extremely rapid mass transfer, the response of a donor star in an interacting binary becomes asymptotically one of adiabatic expansion. We survey here adiabatic mass loss from Population I stars of mass 0.10 Msun to 100 Msun from the zero age main sequence to the base of the giant branch, or to central hydrogen exhaustion for lower main sequence stars. For intermediate- and high-mass stars, dynamical mass transfer is preceded by an extended phase of thermal time scale mass transfer as the star is stripped of most of its envelope mass. The critical mass ratio qad above which this delayed dynamical instability occurs increases with advancing evolutionary age of the donor star, by ever-increasing factors for more massive donors. Most intermediate- or high-mass binaries with nondegenerate accretors probably evolve into contact before manifesting this instability. As they approach the base of the giant branch, however, and begin developing a convective envelope, qad plummets dramatically among intermediate-mass stars, to values of order unity, and a prompt dynamical instability occurs. Among low-mass stars, the prompt instability prevails throughout main sequence evolution, with q_ad declining with decreasing mass. Our calculated qad agree well with the behavior of timedependent models by Chen & Han (2003) of intermediate-mass stars initiating mass transfer in the Hertzsprung gap. Application of our results to cataclysmic variables, as systems which must be stable against rapid mass transfer, nicely circumscribes the range in qad as a function of orbital period in which they are found. These results are intended to advance the verisimilitude of population synthesis models of close binary evolution.

description: This publication brings together over 25 years of accumulated knowledge about the biology and ecology of weeds in cotton that growers can put to practical use in weed management. The weeds studied include three perennials (bermudagrass, johnsongrass, and yellow nutsedge) and four annuals (ivyleaf, morninglory, barnyardgrass, black nightshade, and Palmer amaranth). Although applicable to some extent to all cotton growing states, this knowledge was developed under the irrigated growing conditions of the West (California, Arizona, and New Mexico) and may be most useful in weed management there. The publication addresses four major areas of weed biology and control: (1) plant characteristics that contribute to weed success, (2) weed reintroduction, (3) the influence of weed competition and weed-free periods on yields of cotton and on weed reproduction, and (4) the use of herbicides. The authors present information emphasizing how extensively weeds can damage cotton and suggesting how much weed control cotton can provide for itself.

Diversity and inclusion

description: Collection development is at the core of library services. With growing awareness of diverse communities and the lack of diverse representation in literature and the publishing industry, it is essential that librarians create collection development policies that accurately and effectively advocate for diversity and representation within a library collection. This is especially imperative for youth librarians, who are serving patrons going through a process of identity development and have the potential to be deeply harmed by inaccurate portrayal of their communities.  This study examined how librarians can use collection development policies and ongoing education to curate diverse collections. The study consisted of four semi-structured interviews with librarians and professionals in fields of children’s literature, some of whom are also members of marginalized populations, exploring topics of diverse literature, specific factors librarians should be aware of, and the language participants would like to see explicitly addressed in collection development policies.

description: We study the SU(2) Georgi-Glashow model and suggest a decomposition for its fields and obtain a Lagrangian based on new variables. We use Cho's restricted decomposition as a result of a vacuum condition of the Georgi-Glashow model. This model with no external sources leads us to the Cho extended decomposition. We interpret the puzzling field, $ \textbf{n} $, in Cho's decomposition as the color direction of the scalar field in the Georgi-Glashow model. We also study another constraint, condensate phase, and generalize Cho's extended decomposition. Finally, we argue about a decomposition form that Faddeev and Niemi proposed in this constrained Georgi-Glashow model.

description: This paper focuses on the use of AOL Instant Messenger as a chat reference system in college and undergraduate libraries. A study investigating the advantages and disadvantages of AOL Instant Messenger as a chat reference system in libraries whose primary patrons are college undergraduates was performed. This study examines AOL Instant Messenger from the perspective of the college library patrons, namely undergraduates. The usability and responsiveness of AOL Instant Messenger in a chat reference role was analyzed through thirteen think aloud interviews. Participants in the think aloud interviews asked research questions using Davis Library's Live Online Help and R.B. House Undergraduate Library's IM a Librarian services. The study finds that undergraduates prefer AOL Instant Messenger, primarily because they are familiar with the system and can easily multitask while using it.

description: This paper discusses the effects of stack end signage on user wayfinding success in searches in academic libraries. Site visits to the Chapel Hill Public Library and the Cameron Village Branch Library provided models for test signage for the study, as did the available literature on wayfinding and effective library signage. A three week study was conducted to survey the effects of three different iterations of signage on the success of subjects performing test searches - the  subjects used the UNC Chapel Hill online catalog and the posted signage to locate materials in the Sloane Art Library. The results of the study were evaluated qualitatively and suggestions were made for further study and suggestions for elements of effective academic library signage were made.

Year: 2023

description: In this work, we have developed an FLRW type model of a universe which displays transition from deceleration in the past to the acceleration at the present. For this, we have considered field equations of $f(R,T)$ gravity and have taken $f(R,T) = R + 2 λT$, $λ$ being an arbitrary constant. We have estimated the $λ$ parameter in such a way that the transition red shift is found similar in the deceleration parameter, pressure and the equation of state parameter $ω$. The present value of Hubble parameter is estimated on the basis of the three types of observational data set: latest compilation of $46$ Hubble data set, SNe Ia $580$ data sets of distance modulus and $66$ Pantheon data set of apparent magnitude which comprised of 40 SN Ia binned and 26 high redshift data's in the range $0.014 \leq z \leq 2.26 $. These data are compared with theoretical results through the $ χ^2 $ statistical test. Interestingly, the model satisfies all the three weak, strong and dominant energy conditions. The model fits well with observational findings. We have discussed some of the physical aspects of the model, in particular the age of the universe.

description: This case study examines the process used at a regional medical center to assess the need for an information security officer, and to determine the duties and responsibilities of the position, if it were created. Thirteen administrators from ten different departments or divisions were interviewed to assess the need and support for the creation of an information security officer position, and to inventory the responsibilities that administrators would expect such an officer to fulfill. After the interviews, responses were reorganized, transcribed and tabulated. The recommendations offered and requirements expressed by interview respondents were then compared with recommendations found in the literature on information security officers. Recommendations were made for the creation of an information security officer position, the duties and responsibilities of such a position, and further directions for action and study.

We show the first results of a 2D numerical simulation of dry air convection at high Rayleigh number ($R\sim10^9$). These results are the basis for the later study, by the same method, of wet convection in a solar still.

description: This study examines the potential for electronic full-text journal articles to reduce the level of traditional interlibrary borrowing requests typically placed at a large academic research library. With the growth in availability of electronic full-text journal articles and improvements in accessing and using this formats, library users have access to journal articles not physically owned by their institution's library. This fact may lead to a reduced demand for photocopied journal articles typically requested through interlibrary borrowing departments. This study begins by examining the recent literature on this topic, including several which have measured the impact that electronic full-text resources have had on their interlibrary borrowing levels. This is followed  by a description of the methodology used in this particular study and a presentation of the results. The final section the potential for electronic full-text to reduce the amount of photocopy requests placed through interlibrary borrowing offices.

Subjects: Children's literature

Children--Books & reading

description: Research shows that a large number of children stop reading for pleasure between the second and fifth grade. This critical period coincides with the time that students are transitioning from reading picture books to reading chapter books. This transition may be problematic for several reasons, including whether the books between these levels are available, interesting, and relatable, and if they allow readers to feel successful. Another disturbing trend is the continued lack of children's literature that reflects the racial make-up of the United States. Researchers have found that when readers encounter texts that feature characters like them and with whom they can connect, they are more likely to be interested in books and to see how reading can play a role in their lives. The purpose of this study is to examine transitional books to determine the percentage of main characters and major secondary characters that feature people of color, as well as the percentage of authors that are people of color.

Additional factors influencing records management were employees’ level of records management knowledge, the role and responsibilities of the Chief Records Officer and the level of legal and institutional support the records management programs received. Overall, Chief Records Officers believed they had strong records management programs and adhered to the instructions of the North Carolina Department of Natural and Cultural Resources.
3D cut-cell modelling for high-resolution atmospheric simulations

description: Owing to the recent, rapid development of computer technology, the resolution of atmospheric numerical models has increased substantially. With the use of next-generation supercomputers, atmospheric simulations using horizontal grid intervals of O(100) m or less will gain popularity. At such high resolution more of the steep gradients in mountainous terrain will be resolved, which may result in large truncation errors in those models using terrain-following coordinates. In this study, a new 3D Cartesian coordinate non-hydrostatic atmospheric model is developed. A cut-cell representation of topography based on finite-volume discretization is combined with a cell-merging approach, in which small cut-cells are merged with neighboring cells either vertically or horizontally. In addition, a block-structured mesh-refinement technique is introduced to achieve a variable resolution on the model grid with the finest resolution occurring close to the terrain surface. The model successfully reproduces a flow over a 3D bell-shaped hill that shows a good agreement with the flow predicted by the linear theory. The ability of the model to simulate flows over steep terrain is demonstrated using a hemisphere-shaped hill where the maximum slope angle is resolved at 71 degrees. The advantage of a locally refined grid around a 3D hill, with cut-cells at the terrain surface, is also demonstrated using the hemisphere-shaped hill. The model reproduces smooth mountain waves propagating over varying grid resolution without introducing large errors associated with the change of mesh resolution. At the same time, the model shows a good scalability on a locally refined grid with the use of OpenMP.

description: Bundled electronic journal packages which include all of a publisher's journal titles have been criticized for weakening collections with the inclusion of titles collection developers would not have otherwise selected. Others have claimed it is best to give patrons access to as much information as possible. This study compared the usage of titles to which the University of North Carolina (UNC) subscribes with non-subscribed titles included in the Springer Link electronic journal package. The Chemical Sciences and Medicine subsets of the Springer Link collection were also examined. The results indicated that titles to which UNC subscribes received over five times as much use and were more likely to receive any use at all than non-subscribed titles.

description: The advent of remote, automated renewal services (phone based and web based) have had a significant impact on the way libraries and library materials are used. This paper studies these affects at one university library; Davis Library at the University of North Carolina at Chapel Hill, asking the question, what affect has automated renewal services had on the physical use of Davis Library? Circulation and renewal statistics were looked at from 2000-2004, and exit count numbers were looked at from 2001-2004 in an attempt to answer this question. The statistics show that circulation of library materials has remained relatively stable during the period studied, but that there has been a dramatic increase in the use of automated renewal services, followed by a precipitous decrease in exit counts during the period under study, leading to the conclusion that automated renewal services have led to decreased physical usage of Davis Library.

description: Following the idea of the induced matter theory, for a non-vacuum five-dimensional version of general relativity, we propose a model in which the induced terms emerging from the extra dimension in our four-dimensional space-time, supposed to be as dark energy. Then we investigate the FLRW type cosmological equations and illustrate that when the scale factor of the fifth dimension has no dynamics, in early time the universe expands with deceleration and then in late time, expands with acceleration. In this case, the state parameter of the effective dark energy has a range of $-12Ω_{_{M\circ}}$ which is in agreement with the measurements. We show that the effective energy density of dark energy have been having the same order of magnitude of the effective energy density of matter from the early time in the decelerating epoch of the universe expansion until now. The model avoids the cosmological coincidence problem.

description: We study the electronic transport in an infinite one-dimensional Hubbard chain, driven by a homogeneous electric field. The physical chain is coupled to fermion bath chains, in order to account for dissipation and to prevent the occurrence of Bloch Oscillations. The steady state current is computed in the frame of Keldysh Green's functions in Cluster Perturbation Theory. The current characteristics are dominated by resonant-tunneling-like structures, which can be traced back to Wannier-Stark resonances due to anti-ferromagnetic correlations. The same current characteristic occurs in a non-interacting Wannier-Stark model with alternating on-site energies. Non-local effects of the self energy can be accounted for the observed physical behaviour.

We show that any split fibration between proper groupoids can be made Riemannian, and we use these metrics to linearize proper groupoid fibrations. As an application, we derive rigidity theorems for Lie groupoids, which unify, simplify and improve similar results for classic geometries. Then we establish the Morita invariance for our metrics, introduce a notion for metrics on stacks, and use them to construct stacky tubular neighborhoods and to prove a stacky Ehresmann theorem.

description: This paper describes the functional specifications for an online community to facilitate networking and professional development among the current, former, and future students of the School of Information and Library Science ("SILS") at UNC Chapel Hill. A literature review, surveys conducted on behalf of SILS in the summer and fall of 2002, and a survey conducted in conjunction with this paper in January of 2003 were used to inform the design of the community. In this paper, the evidence supporting a need to create more services for students and alumni is demonstrated, the literature supporting the creation of online communities is examined, and a design for the system is proposed.

description: Due to their qualities to better deal with the unprecedented characteristics of today's VUCA world than conservative project management methods, agile methods have seen an immense upheavel in the industry in recent years – agile methods and the topic of agility in general seem to be inevitable in this context. However, a systematic literature search carried out for the purpose of finding a topic for this master's thesis only confirms this picture to a limited extent: While there is a vast amount of literature on agile methods in project management in general, there is a downright research gap in the more specific field of agile methods in the project management of small and medium sized enterprises (short: SMEs). This insight was taken as an opportunity to bring some light into the dark-ness and to try to fill the existing research gap by attempting to develop a framework for the implementation and utilization of agile methods in the project management of SMEs. In order to create a knowledge base, the theoretical foundation was formed at the very beginning, with a view to both agile project management and SMEs. Subsequently, five specific research questions were defined and a suitable research design was created. In a first round of interviews, twelve problem-centred interviews were conducted with inter-view participants who had experience in the context of agile methods in the project man-agement of SMEs and could report on it. The initial framework based on the resulting findings was then evaluated by five experts in a second round of interviews. After the evaluation of the expert consultation, the initial framework was then modified on the basis of the experts' responses and the final framework was developed. The final framework provides information on what is happening when an agile method is being implemented and later used in the project management of a SME. Therewith, it helps SMEs who are about to introduce an agile method themselves in that they can derive important infor-mation, reference points and recommendations for action from it. For academia, the framework gives rise to further research topics that should be addressed.
Heat Transport in Spin Chains with Weak Spin-Phonon Coupling

description: The heat transport in a system of $S=1/2$ large-$J$ Heisenberg spin chains, describing closely Sr$_2$CuO$_3$ and SrCuO$_2$ cuprates, is studied theoretically at $T\ll J$ by considering interactions of the bosonized spin excitations with optical phonons and defects. Treating rigorously the multi-boson processes, we derive a microscopic spin-phonon scattering rate that adheres to an intuitive picture of phonons acting as thermally populated defects for the fast spin excitations. The mean-free path of the latter exhibits a distinctive $T$-dependence reflecting a critical nature of spin chains and gives a close description of experiments. By the naturalness criterion of realistically small spin-phonon interaction, our approach stands out from previous considerations that require large coupling constants to explain the data and thus imply a spin-Peierls transition, absent in real materials.

description: This study looks at a month's worth of On-line Public Access Catalog (OPAC) transaction logs from the Broyhill Learning Resource Center at Caldwell Community College & Technical Institute in western North Carolina. The study was conducted to look at usage of an OPAC in a smaller library setting; to understand any problems occurring in the OPAC that suggest needed changes in interface design and/or bibliographic instruction; and to identify sets of data that may be useful for the library managers to review on a regular basis. Over 83% of the 5,479 searches performed were executed as subject searches. The heaviest usage of the catalog occurred when classes came in to use the library. About 35% of the searches resulted in zero records being retrieved. Over 60% of the zero-hit searches were caused by problems with the controlled vocabulary. Information from transaction logs should be useful for the library to keep track of system usage, search failure rates, advanced feature usage, and common search strings.

Robust Privacy-Utility Tradeoffs under Differential Privacy and Hamming Distortion

description: A privacy-utility tradeoff is developed for an arbitrary set of finite-alphabet source distributions. Privacy is quantified using differential privacy (DP), and utility is quantified using expected Hamming distortion maximized over the set of distributions. The family of source distribution sets (source sets) is categorized into three classes, based on different levels of prior knowledge they capture. For source sets whose convex hull includes the uniform distribution, symmetric DP mechanisms are optimal. For source sets whose probability values have a fixed monotonic ordering, asymmetric DP mechanisms are optimal. For all other source sets, general upper and lower bounds on the optimal privacy leakage are developed and a necessary and sufficient condition for tightness are established. Differentially private leakage is an upper bound on mutual information (MI) leakage: the two criteria are compared analytically and numerically to illustrate the effect of adopting a stronger privacy criterion.

An exact formula for the $L_2$ discrepancy of the symmetrized Hammersley point set

description: The process of symmetrization is often used to construct point sets with low $L_p$ discrepancy. In the current work we apply this method to the shifted Hammersley point set. It is known that for every shift this symmetrized point set achieves an $L_p$ discrepancy of order $\mathcal{O}\left(\sqrt{\log{N}}/N\right)$ for $p\in [1,\infty)$, which is best possible in the sense of results by Roth, Schmidt and Halász. In this paper we present an exact formula for the $L_2$ discrepancy of the symmetrized Hammersley point set, which shows in particular that it is independent of the choice for the shift.
