Page By Page: An Exploration of Book Disposal Practices in U.S. Public Libraries
Creators: name: Rachel Priesman Marquez
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Weeding is an imperative process to ensure that there is room on the shelves for new materials. When materials are deselected, some books end up in Friends of the Library sales, or are given to third party sources such as Better World Books, but many of these books end up in the trash. The purpose of this study is multifaceted. First, this study aims to discover the amount of book waste created from material deselection for public libraries in the United States. Second, this study seeks to understand librarian’s attitudes about the programs they currently use and any barriers to use that they might experience implementing alternative book disposal programs. The findings indicate that libraries utilize various disposal methods including landfill trash, third-party organizations, and book sales. Libraries also face enormous barriers including staff time and buy-in, space for storing materials, and the cost associated with alternative disposal programs.

description: It is known from the work of Banados et al. that a space-time with event horizons (much like the Schwarzschild black hole) can be obtained from 2+1 dimensional anti-de Sitter space through a suitable identification of points. We point out that this can be done in 3+1 dimensions as well. In this way we obtain black holes with event horizons that are tori or Riemann surfaces of genus higher than one. They can have either one or two asymptotic regions. Locally, the space-time is isometric to anti-de Sitter space.

description: This dissertation explores architectural building types as critical components of, and unique points of interface with, three infrastructural systems, built or re-built in New York City in the decades after World War II. While contemporary infrastructure is enmeshed in regional and global networks far beyond the administrative bounds of the five boroughs, an architectural focus reveals these systems as inescapably local, tied to political struggles surrounding the siting, design, and construction of buildings; to socio-technical imperatives of density; to material consequences like traffic and air pollution; and to aesthetic effects like beauty, monotony, and monumentality. Three case studies—in food distribution, telephone service, and sewage treatment—explore different spatial techniques involved in the management of commodities, information, and waste. Reading each through the social history of technology, as well as the disciplinary tools of architectural history, brings to light unique aspects of architecture’s participation in the political, social, and technological landscapes of the contemporary city. This dissertation looks closely at the prewar roots and postwar creation of New York’s present-day systems: the adoption of the infrastructural buildings we see today, and the rejection of alternatives in design, values, and policies. It argues that the city’s vital systems, and their architectural manifestations, were largely designed according to the needs of various elite groups, in ways that supported the long-term deindustrialization and stratification of urban existence, though not according to a consistent or coherent plan. Well-studied postwar phenomena such as decentralization, automation, demographic change, and “urban crisis” take on different casts as familiar characters like politicians, property owners and architects are joined by monopoly corporations, technicians, and neighborhood organizers. Granular study of the processes that led to the adoption of particular plans, and the rejection of alternatives, reveals the city’s visual and functional landscape as one shaped by a wide—though far from democratic—range of actors. Today, these same infrastructures, physically durable even as their social use has been redirected or transformed, continue to participate in an ostensibly postindustrial and rapidly gentrifying city. By reexamining the narratives of these systems’ design and construction, the study of infrastructural architecture illuminates this inequitable history, while revealing moments of resistance and supporting calls for the further democratization of urban life by those whose needs have been discounted.

description: The Bäcklund transformation for the three-level Maxwell-Bloch equation is presented in the matrix potential formalism. By applying the Bäcklund transformation to a constant electric field background, we obtain a general solution for matched pulses (a pair of solitary waves) which can emit or absorb a light velocity solitary pulse but otherwise propagate with their shapes invariant. In the special case, this solution describes a steady state pulse without emission or absorption, and becomes the matched pulse solution recently obtained by Hioe and Grobe. A nonlinear superposition rule is derived from the Bäcklund transformation and used for the explicit construction of two solitons as well as nonabelian breathers. Various new features of these solutions are addressed. In particular, we analyze in detail the scattering of "invertons", a specific pair of different wavelength solitons one of which moving with the velocity of light. Unlike the usual case of soliton scattering, the broader inverton changes its sign through the scattering. Surprisingly, the light velocity inverton receives time advance through the scattering thereby moving faster than light, which however does not violate causality.

description: Let $R$ be a polynomial ring in $m$ variables over a field of characteristic zero. We classify all rank $n$ twisted generalized Weyl algebras over $R$, up to $\mathbb{Z}^n$-graded isomorphisms, in terms of higher spin 6-vertex configurations. Examples of such algebras include infinite-dimensional primitive quotients of $U(\mathfrak{g})$ where $\mathfrak{g}=\mathfrak{gl}_n$, $\mathfrak{sl}_n$, or $\mathfrak{sp}_{2n}$, algebras related to $U(\widehat{\mathfrak{sl}}_2)$ and a finite W-algebra associated to $\mathfrak{sl}_4$. To accomplish this classification we first show that the problem is equivalent to classifying solutions to the binary and ternary consistency equations. Secondly, we show that the latter problem can be reduced to the case $n=2$, which can be solved using methods from previous work by the authors. As a consequence we obtain the surprising fact that (in the setting of the present paper) the ternary consistency relation follows from the binary consistency relation.

Michael Jackson's Performance of Difference: Dance as Ostracism and Wonderment

Publisher: name: Columbia University
Year: 2013
Subjects: Dance

description: During his reign as the world’s “King of Pop,” Michael Jackson inspired as much fascination with his physical appearance and private life as his artistry. We have seen Jackson portrayed as freak, alien, machine, magician, a new frontier, a cautionary tale, and even a nightmare. However, I’m suggesting that we focus on the underlying theme of difference that exists in Michael Jackson’s artistic work and more specifically, in his body and movement. In this thesis, I approach Michael Jackson’s difference by concentrating on his dancing and delineating it as that which determines his difference and that which helps the audience find likeness in him. That is, the function and power of Jackson’s movement is two-fold: it is both what sets him apart and what permits his acceptance. Ultimately, Jackson demonstrates the intense power of the body and of movement, and the varied influence they can have over his audience’s perception and reception of him. My thesis can be broken down into two parts: the problem Michael Jackson’s difference poses for society, and the response, in which Jackson has adopted and responded to the problem of his difference in order to deflect political issues.
Examining the Role and Neurophysiological Mechanisms of Social Support in Pain Experience

description: Social support plays a role in pain experience, however, this effect is context-dependent. The findings presented here suggest that social support generally has a protective effect on pain, particularly when it is clearly expressed by a significant other. In addition, the analgesic influence of social support may be associated with the buffering of neurophysiological stress systems to pain, impacting on the integration and gating of pain signals. It is hoped that this body of work will contribute to the understanding of the effects and potential mechanisms of social support in pain.

In addition to being the records repository, UNC-CH’s UARMS strives to include the experience of the larger university community. When the COVID-19 pandemic began in March 2020, UARMS began collecting materials documenting the events as they affected the students, staff, faculty and members of the larger Chapel Hill community in order to preserve a diverse array of voices as a balance against the institutional university record. This assessment of the collection looked at what voices were included and how effective it was in reflecting the community experience. Overall, the collection accomplishes the goal of including those voices and preserving a community viewpoint of the first two years of the pandemic.

description: This study presents a novel Multi-Scale Fusion-based Customized ResNet152 (MSF-Customized ResNet152) model for lung cancer segmentation and classification, designed to address challenges in class imbalance and feature extraction. The model combines multi-scale feature fusion with depth-wise separable convolution to capture fine and broad image details, enhancing segmentation accuracy. To address the minority representation of cancerous regions, a weighted recall loss was integrated with cross-entropy loss, optimized via Grid Search, to increase sensitivity. Additionally, data augmentation techniques were applied to expand the cancerous image set, further improving detection robustness. The model was evaluated on two datasets: a chest CT-scan dataset and a lung and colon cancer histopathology dataset. Using a 5-fold cross-validation approach, the MSF-Customized ResNet152 achieved a classification accuracy of 98.5%, precision of 98.2%, specificity of 97.2%, F1-score of 97.4%, and Dice coefficient of 97.3%. Comparative analysis demonstrated the superiority of the combined recall and cross-entropy loss function over standard methods, validating the model's effectiveness in handling class imbalance.

description: Let X be a smooth toric variety. David Cox introduced the homogeneous coordinate ring S of X and its irrelevant ideal B. Extending well-known results on projective space, Cox established the following: (1) the category of quasi-coherent sheaves on X is equivalent to the category of graded S-modules modulo B-torsion, (2) the variety X is a geometric quotient of Spec(S) V(B) by a suitable torus action. We provide the D-module version of these results. More specifically, let A denote the ring of differential operators on Spec(S). We show that the category of D-modules on X is equivalent to a subcategory of graded A-modules modulo B-torsion. Additionally, we prove that the characteristic variety of a D-module is a geometric quotient of an open subset of the characteristic variety of the associated A-module and that holonomic D-modules correspond to holonomic A-modules.

description: In 1561, an 86 year old Michelangelo Buonarotti was asked by Pope Pius IV to design a church in the city of Rome. At the time Michelangelo was already living in Rome, designing another church, St. Peters Basilica, for which he had just completed the wood model of the massive dome. He did not need this new commission for financial or status purposes, but Michelangelo had a restless spirit, which pushed him into achieving greater goals. He was attracted more by a new challenge than by the idea of actually finishing what he had begun. This commission was unequivocally something new for the artist to test the abilities he had perfected throughout his life and, in doing so, he created a final architectural masterpiece. The commission for Santa Maria degli Angeli was not meant to be a new construction project, but rather, it was an adaptation of the ruined ancient roman thermae; The Baths of Diocletian. In this reuse, Michelangelo's design of Santa Maria degli Angeli e dei Martiri within the ruins is a clear instance of a deliberate reuse of an existing structure by an architect; one that was not an assertion of power nor an accretion of material, but rather an architectural intervention that embraced change and provided a rebirth for a decaying structure. It has always been known that the church was built within the fabric of a ruin, but now, from a contemporary vantage point, what can be gained by re-framing it? Piecing together the history and architecture to create a basic understanding of why this project was successful; not as a new construction, but as an adaptive reuse. From the understanding of the site and 16th century preservation efforts, to an analysis of the circulation and materiality within the church, this thesis will examine Michelangelo's design to better understand his strategy.

description: MicroBooNE is a liquid argon time projection chamber that collected neutrino data at Fermilab's Booster Neutrino Beam from 2015 to 2020. One of its primary goals is to investigate the “Low Energy Excess” of neutrino events observed by the MiniBooNE experiment, for which candidate photon-like interpretations include an underestimation of neutrino neutral current (NC) resonant Δ production with subsequent radiative decay or another anomalous source of single photon production in neutrino interactions. In particular, NC Δ radiative decay is poorly constrained background process to electron neutrino measurements and could be a sizable contribution to the “Low Energy Excess.” This thesis will present the analysis developed to search for NC Δ → N𝛾 events in MicroBooNE, consisting of a boosted decision tree based event selection with an NC neutral pion background constraint, using data from the first three years of operations corresponding to 6.9 × 10²⁰ POT.

description: This thesis describes work towards the search for a low energy excess of electromagnetic events in the MicroBooNE detector. A background primer on the current state of neutrino physics is provided, including a description of the MiniBooNE detector and its published observation of an excess of electromagnetic events at low energies. A description of the MicroBooNE Liquid Argon Time Projection Chamber (LArTPC) detector is given, along with a description of the event selection and reconstruction algorithms developed to select electron neutrino charge-current interactions. A MiniBooNE-like signal is simulated in MicroBooNE with assumptions about the origin of the excess, and the sensitivity to observe such a signal above backgrounds in MicroBooNE is computed. An additional analysis is presented which constrains a dominant background in the MicroBooNE low energy excess search: the beam-intrinsic electron neutrino interactions which come from kaon decay in the beam-line. An essential step in this analysis is to reconstruct the energy of muon neutrino charge-current interactions in which the muon produced in the interaction escapes the detector. A publication detailing the algorithm which leverages the phenomenon of multiple Coulomb scattering to reconstruct the energy of escaping muons is provided as an appendix.
Micro-Evaporator Design and Investigation of Phase Change in Tailored Microchannels

description: Microchannels show promising potential for implementation in next generation high heat flux cooling schemes. Promising research has been conducted in the area of MEMS cooling devices, taking advantage of the increased heat transfer characteristics in microfabricated structures. While significant advances in microchannels can be found in the literature, little work is being done to develop microchannels with non-uniform cross sections that can evaporate fluid without the presence of the bubbles at the exit flow. This thesis presents an experimental study of flow evaporation in micro-evaporators with tailored microchannel walls, demonstrating the ability to provide a stable flow of evaporated fluid for energy conversion and chip cooling applications. The design and modeling approach, microfabrication process and the full testing of the micro-evaporators are a part of this study and are all presented. Two mechanisms are proposed to stabilize the internal flow evaporation. The first mechanism is to establish a temperature gradient along the channel to separate the room temperature inlet fluid from the steam exit flow. The second mechanism is to change the direction of the surface tension forces acting on the meniscus to fix its position along the channel. The test device used in this work consists of a silicon wafer with through-etched complex microchannels that is anodically bonded to a glass wafer on each side. Inlet and exit holes for the fluid are machined in the glass wafers. Water is forced through the chip while it is heated on the exit side of the three layer chip. The qualitative nature of the two-phase flow along the shaped channels is observed through the glass cover wafer, for different flow rates and wall temperatures. The work also provides a comparative study between different channel designs, different boundary conditions which reveal the benefits of the shaped microchannels with temperature gradient. The temperature gradient achieved with different thickness of channel walls shows agreement with the modeling results. Also, the benefit of having multiple expansions in the channels was demonstrated. By using these two mechanisms the onset of water evaporation was fixed along the channel. The behavior of the meniscus in a microchannel with complex geometries and with a temperature gradient along it is quite encouraging in the perspective of the phase change in microchannels. These results of this research provide a design basis for a broad range of micro thermal systems, or Power MEMS, for chip cooling and micro power generation.

description: A strategy for aqueous film-forming foam (AFFF) using cationic-anionic surfactant mixtures with short fluorocarbon chains (≤C4) in both cationic and anionic surfactants was proposed. The minimum surface tension (γmin) of mixtures of C4F9SO2NH(CH2)3N(CH3)3I (C4FI) and CnF2n+1COONa (n = 1, 2, 3, 4) with different molar ratios (5:1, 2:1, 1:1, 1:2, 1:5) was measured at 25 °C. The γmin for all mixtures of C4FI–CnF2n+1COONa were remarkably lower than that of pure C4FI. Among these mixtures, the equimolar mixture of C4FI–C3F7COONa was chosen because of the low γmin, qualified solubility and relatively high fluorine efficiency. The spreading coefficients of its aqueous solution on n-heptane, toluene, benzene, cyclohexane and gasoline were all positive, indicative of its potential in AFFF. The film spreading, sealability and foaming were also tested. The influences of ‘green’ additives (alkyl glucose amide, xanthan gum and sodium carboxymethylcellulose) on foaming performance were studied, in which small dosage of xanthan gum could greatly retard the drainage of foam. It was confirmed that the mixing of oppositely charged surfactants both possessing short fluorocarbon chains was a valuable thought to design AFFF. In application, the quaternary ammonium surfactant likewise can be bromide or chloride rather than iodide for reasons of cost-reduction and stability.
Micro-data in Macroeconomics

Industrial productivity

description: This dissertation contains three essays on Macroeconomics. Detailed micro-level data is used in all three essays. The first chapter studies wealth inequality problems. More specif- ically, it focuses on capital return inequality among university endowments. It combines university-level data on endowment size, capital returns, and portfolio allocations into a unified dataset. Using panel data regression, I show a strong impact of size on investment return. Everything else the same, the biggest endowment has a capital return 8 percent higher than the smallest endowment. However, after adjusting for risk using Sharpe ratios, the strong positive correlation turns negligible or even negative. This result suggests that the higher return of bigger endowments can be attributed to risk compensation rather than to an informational premium.
      The second and the third chapters employ firm-level data to study macroeconomic pro- ductivity. The second chapter documents the sectoral growth paths of measured total factor productivity (TFP) in southern Europe during the boom that proceeded the great contraction (1996 to 2007). Using both aggregate and firm-level panel data, I show that TFP in sectors that displayed fast expansion, such as construction, dropped significantly, while in non- expanding sectors, such as manufacturing, it stayed stable. I evaluate the relevance of two alternative explanations of this phenomenon: capital misallocation (the increase in capital was directed to less productive firms) and labor quality mismeasurement (lower quality of incoming labor was not fully captured in the TFP calculation). I find that the misalloca- tion channel is almost negligible. Moreover, worker-firm matched data shows that labor quality did deteriorate in the expanding sectors but not in the others, giving credence to the labor-quality mismeasurement hypothesis. A model featuring both the misallocation and the mismeasurement channels and calibrated to match the micro-level productivity distri- bution and labor quality distribution predicts that the drop in true TFP was small if labor quality is measured properly.
      The third chapter documents the total factor productivity growth path in China from 1998 to 2015 using both the aggregate and the firm-level data. We find that measured TFP growth is positive from 1998 to 2011, before turning flat and even negative. A care- ful comparison between state-owned enterprises (SOEs) and private firms reveals that the slowing down of TFP growth of SOEs is the major contributor to the TFP growth reversal of the whole manufacturing sector. The reversal is not due to changes in the composition of production in different sub-sectors, but mostly due to changes within existing firms.

description: Objective: To evaluate alterations in apparent axon diameter and axon density obtained by high-gradient diffusion MRI in the corpus callosum of MS patients and the relationship of these advanced diffusion MRI metrics to neurologic disability and cognitive impairment in MS. Methods: Thirty people with MS (23 relapsing-remitting MS [RRMS], 7 progressive MS [PMS]) and 23 healthy controls were scanned on a human 3-tesla (3T) MRI scanner equipped with 300 mT/m maximum gradient strength using a comprehensive multishell diffusion MRI protocol. Data were fitted to a three-compartment geometric model of white matter to estimate apparent axon diameter and axon density in the midline corpus callosum. Neurologic disability and cognitive function were measured using the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Functional Composite (MSFC), and Minimal Assessment of Cognitive Function in MS battery. Results: Apparent axon diameter was significantly larger and axon density reduced in the normal-appearing corpus callosum (NACC) of MS patients compared to healthy controls, with similar trends seen in PMS compared to RRMS. Larger apparent axon diameter in the NACC of MS patients correlated with greater disability as measured by the EDSS (r = 0.555, P = 0.007) and poorer performance on the Symbol Digits Modalities Test (r = -0.593, P = 0.008) and Brief Visuospatial Memory Test-Revised (r = 0.632, P < 0.01), tests of interhemispheric processing speed and new learning and memory, respectively. Interpretation: Apparent axon diameter in the corpus callosum obtained from high-gradient diffusion MRI is a potential imaging biomarker that may be used to understand the development and progression of cognitive impairment in MS.

The liaison between matrix Dirac equation and standard Dirac equation is discussed. We write a lagrangian from which matrix Dirac equation can be derived. This lagrangian is invariant under global unitary transformations of variables. The requirement of a local (gauge) invariance of lagrangian leads us to lagrangian with gauge fields.

description: We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 2017eaw is a normal SN II-P intermediate in properties between, for example, SN 1999em and SN 2012aw and the more luminous SN 2004et, also in NGC 6946. We have determined that the extinction to SN 2017eaw is primarily due to the Galactic foreground and that the SN site metallicity is likely subsolar. We have also independently confirmed a tip-of-the-red-giant-branch (TRGB) distance to NGC 6946 of 7.73+/-0.78 Mpc. The distances to the SN that we have also estimated via both the standardized candle method and expanding photosphere method corroborate the TRGB distance. We confirm the SN progenitor identity in pre-explosion archival Hubble Space Telescope (HST) and Spitzer Space Telescope images, via imaging of the SN through our HST Target of Opportunity program. Detailed modeling of the progenitor's spectral energy distribution indicates that the star was a dusty, luminous red supergiant consistent with an initial mass of ~15 Msuns.

description: The Ordovician Lagerstätten record substantial amounts of excellent preservation and soft-bodied fossils during the Great Ordovician Biodiversification Event (GOBE). However, few Lagerstätten are known from the Lower Ordovician, most of which are preserved in restricted environments and high-latitude regions. Here, we report on a new tropical Lagerstätte, Liexi fauna, which has been recently discovered from a carbonate succession within the Lower Ordovician Madaoyu Formation in western Hunan, South China. It contains a variety of soft tissues, as well as rich shelly fossils, including palaeoscolecidan worms, possible Ottoia, trilobites, echinoderms, sponges, graptolites, polychaetes, bryozoans, conodonts and other fossils. The fauna includes taxa that are not only Cambrian relics, but also taxa originated during the Ordovician, constituting a complex and complete marine ecosystem. The coexistence of the Cambrian relics and Ordovician taxa reveals the critical transition between the Cambrian and Palaeozoic Evolutionary faunas. The unusual Liexi fauna provides new evidence for understanding Ordovician macroevolution and the onset of the GOBE.

description: Pflegefamilien gehören in vielen Ländern zum festen Angebot der Jugendhilfe. Insbesondere für kleine Kinder, die nicht bei ihren Eltern leben können, bieten sie die Möglichkeit, in einem familiären Setting aufzuwachsen und verlässliche, kontinuierliche Bezugspersonen zu erleben. Die Schwierigkeiten, die wir in der deutschen Hilfelandschaft damit erfahren, stellen auch in anderen Ländern Recht und Praxis vor die Herausforderung, diese so gut wie möglich und unter Berücksichtigung des Stands in Wissenschaft und Forschung aufzulösen.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The non-minimal coupling of gravity to a scalar field can be transformed into a minimal coupling through a conformal transformation. We show how to connect the results of a perturbation calculation, performed around a Friedmann-Robertson-Walker background solution, before and after the conformal transformation. We work in the synchronous gauge, but we discuss the implications of employing other formalisms.

Ekati Diamond Mine™ processed kimberlite reclamation
Creators: name: Reid, Neil B.

Publisher: name: The University of British Columbia
Year: 2009

description: The option to establish a vegetation cover over a rock cover to stabilize processed kimberlite tailings after diamond extraction has prompted revegetation research at the Ekati Diamond Mine™ in the Canadian subarctic barrenlands. Laboratory testing has shown coarse texture, no organic component and lack of available macronutrients to be the principal limitations to plant colonization. This study aims to ameliorate these plant growth limitations to establish a permanent self-sustaining vegetation cover on the Ekati kimberlite tailings containment area, stabilizing the surface materials and promoting natural colonization by the surrounding tundra vegetation. With the addition of structural improving and nutrient providing amendments, plant growth on these kimberlite tailings has shown promise. Successful amendment combinations have included peat moss or papermill waste in combination with biosolids from the mine site and/or fertilizer.
Solitons from Dressing in an Algebraic Approach to the Constrained KP Hierarchy

description: The algebraic matrix hierarchy approach based on affine Lie $sl (n)$ algebras leads to a variety of 1+1 soliton equations. By varying the rank of the underlying $sl (n)$ algebra as well as its gradation in the affine setting, one encompasses the set of the soliton equations of the constrained KP hierarchy. The soliton solutions are then obtained as elements of the orbits of the dressing transformations constructed in terms of representations of the vertex operators of the affine $sl (n)$ algebras realized in the unconventional gradations. Such soliton solutions exhibit non-trivial dependence on the KdV (odd) time flows and KP (odd and even) time flows which distinguishes them from the conventional structure of the Darboux-Bäcklund Wronskian solutions of the constrained KP hierarchy.

description: Zeitgleich mit dem Abbau des Sozialstaates, der in Deutschland unter dem Stichwort Umbau statt Ausbau beworben wurde, und der Auslagerung von Sozialen Diensten an privatwirtschaftlich geführte Organisationen geht der Begriff Klient bzw. KlientIn in zunehmender Weise verloren und wird durch den Kundenbegriff ersetzt. Dies wird häufig als emanzipatorischer Akt dargestellt. Wenn nun auch in der Sozialen Arbeit der Klient zum Kunden und dadurch zum König wird, sollte endlich eine veraltete paternalistische Haltung aufgegeben werden. Die Autorin beschreibt die zwei unterschiedlichen Arten von Ökonomien, die den Hintergrund für die Begriffe KlientIn und KundIn ausmachen und geht dann der Frage nach, ob der Begriff des Kunden bzw. der Kundin auch für die NutznießerInnnen Sozialer Arbeit geeignet ist.
