A Portal to Middle Earth: The Dodge Collection of Tolkien Books & Ephemera
Creators: name: Dodge, Lily
Publisher: name: Maryland Shared Open Access Repository
Year: 2012

description: Applestein-Sweren Book Collecting Prize: First Place
description: My entry for the 2012 Applestein-Sweren Prize is my collection of books and ephemera related to J.R.R. Tolkien’s Lord of the Rings fantasy series. A focus on Tolkien’s work is the primary unifying theme of the collection, which includes a number of Tolkien’s books and writings, commentary and scholarship on his work, and interpretive artwork from a number of sources. While a Lord of the Rings collection existing in 2012 must in some ways acknowledge the three films directed by Peter Jackson, this collection intentionally does not include the films themselves or promotional or supplemental materials from the films, except as represented in two items: a handmade scrapbook collecting media related to the release of the final film and a printed screenplay. When I began my collection, its primary purpose was to allow me to develop and deepen my knowledge of Middle-earth and its fantasy reality, so works about Tolkien himself are rare as well. Most of the writings in my collection, including the scholarly commentary, take Middle-earth on its own terms. My primary intention when creating this collection was to allow for complex and complete internal experiences of Tolkien’s fantasy world.

description: The general construction of frames of p-adic wavelets is described. We consider the orbit of a mean zero generic locally constant function with compact support (mean zero test function) with respect to the action of the p-adic affine group and show that this orbit is a uniform tight frame. We discuss relation of this result to the multiresolution wavelet analysis.

Fourier transform microwave spectroscopy of lanthanum monohalides
Creators: name: Rubinoff, Daryl Simon
Publisher: name: University of British Columbia
Year: 2009

description: The pure rotational spectra of the X¹Σ⁺ ground states of the lanthanum monohalides, ¹³⁹LaF, ¹³⁹LaCl, ¹³⁹LaBr and ¹³⁹Lal, have been measured using a pulsed-jet cavity Fourier transform microwave spectrometer in the range of 5-24 GHz. The molecules were prepared by ablating solid La with the second harmonic of a pulsed Nd:YAG laser and allowing the vapor to react with SF₆ , CI₂, Br₂ or CH₃I precursor present as < 0.01% in an Ar carrier gas. Only the J=1-0 rotational transition of LaF was measurable within the frequency range of the spectrometer, while multiple J transitions have been recorded for both La³⁵Cl and La³⁷Cl. The ground and first excited vibrational levels (v=0 and u=l) of LaF, La³⁵Cl and La³⁷Cl were recorded with an additional vibrational level, v=2, measured for LaF. Equilibrium geometries of LaF and LaCl have been evaluated and indicate a significant mass dependency indicating Born-Oppenheimer breakdown. The vibrational frequency, ωe, vibrational anharmonicity constant, ωeXe, and the dissociation energies have been estimated for both molecules and agree very well with the literature values. Several rotational transitions have been measured and are reported for La⁷⁹Br and Lal in both the ground and first vibrational levels with only v=0 data collected for La⁸¹Br. For LaBr, this is the first reported observed spectrum and analysis thereof. Equilibrium geometries have been evaluated along with estimates of the vibrational frequency, ωe, vibrational anharmonicity constant, ωeXe, and the bond dissociation energy, De, for La⁷⁹Br and Lal. Hyperfine structure due to lanthanum and halogen nuclei has been observed and used to determine nuclear quadrupole coupling constants and spin-rotation coupling constants for all nuclei with exception of fluorine which has no quadrupole moment. Using nuclear quadrupole coupling data, LaCl, LaBr and Lal were all found to be highly ionic and generally follow trends predicted based on electronegativity differences of related species. Magnetic shielding parameters have been calculated from nuclear spin-rotation coupling constants and are reported herein.

description: Critical current was recently measured near the transition from 0 to $π$-contact in superconductor/ferromagnet/superconductor Josephson junctions. Contrary to expectations, it does not vanish at the transition point. It shows instead a tiny, though finite, minimum. The observation of fractional Shapiro steps reenforces the idea that the vanishing of the main sinusoidal term in the Josephson relation gives room to the next harmonics. Within quasiclassical approach we calculate the Josephson relation taking into account magnetic scattering. We find that the observed minimum is compatible with the value of the second harmonics expected from the theory.

description: We study the existence of standing waves, of prescribed $L^2$-norm (the mass), for the nonlinear Schrödinger equation with mixed power nonlinearities $$ i \partial_t ϕ+ Δϕ+ μϕ|ϕ|^{q-2} + ϕ|ϕ|^{2^* - 2} = 0, \quad (t, x) \in R \times R^N, $$ where $N \geq 3$, $ϕ: R \times R^N \to C$, $μ> 0$, $2 < q < 2 + 4/N $ and $2^* = 2N/(N-2)$ is the critical Sobolev exponent. It was already proved that, for small mass, ground states exist and correspond to local minima of the associated Energy functional. It was also established that despite the nonlinearity is Sobolev critical, the set of ground states is orbitally stable. Here we prove that, when $N \geq 4$, there also exist standing waves which are not ground states and are located at a mountain-pass level of the Energy functional. These solutions are unstable by blow-up in finite time. Our study is motivated by a question raised by N. Soave.

description: The research for my play was divided into three major categories: I looked at female romantic friendship at the turn of the 20th century, college life for women around 1900, and the ways in which female-female romantic relationships have been previously represented on the stage. I used both Goucher’s physical and online collections to access these resources, and the materials that Goucher did not own I was able to access through the Interlibrary Loan system. Additionally, Goucher’s archives have proven to be an invaluable resource for this project. I was able to use primary sources such as yearbooks and scrapbooks to delve into my research about life at a women’s college. I found a multitude of details that have helped to provide the play with the appropriate historical texture. While I was primarily focused on learning about daily life, I was pleasantly surprised when I stumbled upon mentions of romantic friendships between students. I learned the importance of reading and analyzing primary sources thoroughly and carefully. Since, unlike secondary sources, they rarely include indexes, discoveries are made by examining the source in total instead of immediately flipping to the relevant section. Therefore, finding highly pertinent information becomes all the more rewarding.
Furthermore, I learned how to synthesize factual information and creative impulses and to strike an appropriate balance between historical accuracy and artistic license. I found multiple (and occasionally contradictory) arguments about the emerging queer consciousness of the early 20th century and all of them informed my characters’ perceptions of female romantic friendship. I evaluated the differing points of view for evidentiary accuracy and bias and I reached the conclusion that perhaps there are differing theories because there was more than one way of perceiving female-female love at the time. These variations are represented throughout the play.

description: In response to the recent outbreaks of food-borne illness, the 'Good Agricultural Practices' program has been widely adopted to ensure consistency of food safety. This paper presents a theoretical framework to analyze the performance of the program with respect to output quality based on the assumption of predetermined productive capacity (farm size), heterogeneous farms and exogenous detection. Our main results are: (i) farms respond to the monitoring and enforcement not only by reducing fraudulent output, but also by increasing truly high-safety output until the perfect compliance level is achieved. (ii) the monitoring agency takes farm strategies as given and its optimal inspection policies are: If the monitoring budget is not enough to cover the necessary inspection cost of achieving perfect high-safety output level, it will allocate resources to farms with larger size and lower costs; If the budget is enough to obtain perfect level of high-safety output but is not enough to eliminate fraudulent output completely, the monitoring agency will expend equal effort on all the farms.
Panoramic Views of Cluster-Scale Assemblies Explored by Subaru Wide-Field Imaging

description: We have started PISCES project; a panoramic imaging and spectroscopic survey of distant clusters on Subaru. It exploits the unique wide-field imaging capability of Suprime-Cam, which provides a 34'x27' field of view corresponding to a physical area of 16x13Mpc^2 at z~1. We plan to target 15 clusters in total at 0.45Mpc from the cores, as well as complex inner structures. The galaxy distributions in the inner regions of the clusters look similar to the X-ray intensity maps, suggesting that most of the optical structures trace physically bound systems. We also compared the structures of the three clusters with those of model clusters in a numerical simulation (N-body + semi-analytic model) by parameterising the shapes of the iso-density contours of galaxies, and found a broad agreement. Our results provide good evidence that cluster-scale assembly takes place along filaments during hierarchical clustering, while the structures found here need to be confirmed spectroscopically in the near future.

description: We examine two exactly solvable models of decoherence -- a central spin-system, (i) with and (ii) without a self--Hamiltonian, interacting with a collection of environment spins. In the absence of a self--Hamiltonian we show that in this model (introduced some time ago to illustrate environment--induced superselection) generic assumptions about the coupling strengths can lead to a universal (Gaussian) suppression of coherence between pointer states. On the other hand, we show that when the dynamics of the central spin is dominant a different regime emerges, which is characterized by a non--Gaussian decay and a dramatically different set of pointer states. We explore the regimes of validity of the Gaussian--decay and discuss its relation to the spectral features of the environment and to the Loschmidt echo (or fidelity).

description: The Tianlai Dish Pathfinder Array is a radio interferometer designed to test techniques for 21~cm intensity mapping in the post-reionization universe as a means for measuring large-scale cosmic structure. It performs drift scans of the sky at constant declination. We describe the design, calibration, noise level, and stability of this instrument based on the analysis of about $\sim 5 \%$ of 6,200 hours of on-sky observations through October, 2019. Beam pattern determinations using drones and the transit of bright sources are in good agreement, and compatible with electromagnetic simulations. Combining all the baselines, we make maps around bright sources and show that the array behaves as expected. A few hundred hours of observations at different declinations have been used to study the array geometry and pointing imperfections, as well as the instrument noise behaviour. We show that the system temperature is below 80~K for most feed antennas, and that noise fluctuations decrease as expected with integration time, at least up to a few hundred seconds. Analysis of long integrations, from 10 nights of observations of the North Celestial Pole, yielded visibilities with amplitudes of 20-30~mK, consistent with the expected signal from the NCP radio sky with $<10\,$mK precision for $1 ~\mathrm{MHz} \times 1~ \mathrm{min}$ binning. Hi-pass filtering the spectra to remove smooth spectrum signal yields a residual consistent with zero signal at the $0.5\,$mK level.

description: Agricultural producers have been experiencing significant income pressures, leading to a search for alternative sources of income. One of such is value-added agricultural businesses that allow the farmers to stay on the farm and undertake entrepreneurial ventures to improve their finances. How do farmers make sense of their environment as they consider their options for value-added business ventures? This paper presents a sensemaking model and links it to entrepreneurship decisions, allowing us to explain how producers may make such decisions.

description: After visiting the Baltimore Museum of Art and selected which painting I would focus on for this paper, I was able to employ many of the library’s resources. Our class was structured in a manner that enabled research to be done methodically. After selecting what object we’d like to write on, we were instructed to compose a visual analysis; this proved to be a great way to get our intellectual juices flowing. With the aid of the visual analysis, I was able to come up with a topic that interested me, and would be researchable.
The next stage was compiling an annotated bibliography. In order to do this I did a keyword search of the library catalog. This supplied a plethora of print resources that I was able to track down and sift through. In addition to the library catalog search, I also used the online journal search, on JSTOR and other Academic Journal catalogs.
After selecting numerous sources—there was a requirement of ten—I spent time reading through each book and article in order to get a general sense of the main themes of each piece. Once I had decided which sources were necessary for my paper I read them more thoroughly: highlighting and underlining pertinent passages. I kept each article in a giant envelope and marked what days I had read what article to keep track of all sources.
This methodical and organized structure of researching was the most important thing I learned about the research process. By taking the researching process one step at a time, I was able to fully absorb the points of view of each of my sources and then decide where these viewpoints merged with my own, and where they didn’t. As such, I was able to formulate a developed argument and support that with the research I’d accumulated.

The variable has an X-ray counterpart detected on images taken with the ROSAT telescope. Although we cannot offer proof of cluster membership, one can see that both the position on the H-R diagram and the X-ray flux are consistent with a bright DN at the cluster distance. According to our outburst statistics, no more than one similar DN could remain undetected in our field of view, centred at the cluster core.

description: We provide a general self-attention formulation to impose group equivariance to arbitrary symmetry groups. This is achieved by defining positional encodings that are invariant to the action of the group considered. Since the group acts on the positional encoding directly, group equivariant self-attention networks (GSA-Nets) are steerable by nature. Our experiments on vision benchmarks demonstrate consistent improvements of GSA-Nets over non-equivariant self-attention networks.

description: Estimating how production contracts affect farm productivity is difficult because the decision to use a contract is endogenous to other decisions affecting productivity. This study uses the local availability of production contracts as an instrument for whether a farm uses a contract in order to estimate the impact of contract use on total factor productivity. Results indicate that use of a production contract is associated with a large increase in productivity for feeder-to-finish hog farms in the U.S. The instrumental variable method makes it credible to assert that the observed association is a causal relationship rather than simply a correlation.

We explain how the physical fusion of vortex-antivortex pairs allows us to use these rules to read out the information encoded in the topologically protected space of degenerate ground states. We comment on the potential applicability of this fact to quantum computation. Modified 11/30/05 to reflect manuscript as accepted for publication. Includes corrected last section.

description: This paper develops a stochastic model for estimating potential loan deficiency payments to U.S. corn producers in a discrete-dynamic context. We minimize the potential for misspecification bias by using nonparametric and semi-nonparametric approaches as specification checks in the model. The model permits the forecast at planting time of the resulting empirical distribution of LDP payments for that crop year. Using this model, the paper examines the sensitivity of this distribution to changes in expected price levels.

description: We consider the problem of learning the true ordering of a set of alternatives from largely incomplete and noisy rankings. We introduce a natural generalization of both the classical Mallows model of ranking distributions and the extensively studied model of noisy pairwise comparisons. Our selective Mallows model outputs a noisy ranking on any given subset of alternatives, based on an underlying Mallows distribution. Assuming a sequence of subsets where each pair of alternatives appears frequently enough, we obtain strong asymptotically tight upper and lower bounds on the sample complexity of learning the underlying complete ranking and the (identities and the) ranking of the top-k alternatives from selective Mallows rankings. Moreover, building on the work of (Braverman and Mossel, 2009), we show how to efficiently compute the maximum likelihood complete ranking from selective Mallows rankings.

description: The projected entangled pair state (PEPS) representation of quantum states on two-dimensional lattices induces an entanglement based hierarchy in state space. We show that the lowest levels of this hierarchy exhibit an enormously rich structure including states with critical and topological properties as well as resonating valence bond states. We prove, in particular, that coherent versions of thermal states of any local 2D classical spin model correspond to such PEPS, which are in turn ground states of local 2D quantum Hamiltonians. This correspondence maps thermal onto quantum fluctuations, and it allows us to analytically construct critical quantum models exhibiting a strict area law scaling of the entanglement entropy in the face of power law decaying correlations. Moreover, it enables us to show that there exist PEPS within the same class as the cluster state, which can serve as computational resources for the solution of NP-hard problems.

description: The paper reports results of non-parametric analysis of peanut, corn, and cotton yield distributions by the ElNino Southern Oscillation (ENSO) phases in the Southeastern U.S. For validation purposes, the historical yield data is complemented by a set of simulated peanut yields generated using daily weather data. The hypothesis, justified by the observed South-Eastern climate differences and research on ENSO cycles and planting dates, is that different climate conditions during ENSO cycles translate into different yield distributions and, therefore, insurance premiums (loss to coverage ratios). Kernel density estimates of historical county yield data show consistent patterns in the actuarially fair rate schedules grouped by ENSO phases and geographical areas. In particular, corn and cotton yield insurance premiums appear to be the most dependent on the ENSO phases and are the highest, regardless of coverage, during ElNino and the lowest during LaNina. Peanut premiums are higher during Neutral years and lowest during LaNina. The results appear to be robust to the transformations used to make the yield series stationary. While these dependencies do not necessarily correspond to the precipitation and solar radiation characteristics of the corresponding ENSO cycles in the Southeastern US, drawing direct analogies with yield variability is premature as many less documented factors, like the spacing of sunny and rainy days, may be just as important. The comparisons of the empirical and simulated peanut yield distributions show that they are similar in many ways and that the dissimilarities can be explained by known factors. These findings should be more relevant for the area yield insurance as opposed to the APH arrangements as the yield data used in designing contracts for the former reflects the systemic risk more influenced by climate than by the farm-level, basis risk factors accommodated in the APH plans.

description: In first-order cosmological phase transitions, the asymptotic velocity of expanding bubbles is of crucial relevance for predicting observables like the spectrum of stochastic gravitational waves, or for establishing the viability of mechanisms explaining fundamental properties of the universe such as the observed baryon asymmetry. In these dynamic phase transitions, it is generally accepted that subluminal bubble expansion requires out-of-equilibrium interactions with the plasma which are captured by friction terms in the equations of motion for the scalar field. This has been disputed in works pointing out subluminal velocities in local equilibrium arising either from hydrodynamic effects in deflagrations or from the entropy change across the bubble wall in general situations. We argue that both effects are related and can be understood from the conservation of the entropy of the degrees of freedom in local equilibrium, leading to subluminal speeds for both deflagrations and detonations. The friction effect arises from the background field dependence of the entropy density in the plasma, and can be accounted for by simply imposing local conservation of stress-energy and including field dependent thermal contributions to the effective potential. We illustrate this with explicit calculations of dynamic and static bubbles for a first-order electroweak transition in a Standard Model extension with additional scalar fields.

description: On the invalidity of the name Amynthas corticis saeseum Blakemore, 2013
Blakemore (2013a, p. 26) described Amynthas corticis saeseum from Saeseum Island, South Korea with DNA sample of the holotype labeled as w33. Blakemore (2013a) states in the remarks section that " Amynthas corticis saeseum is possibly a ‘proto-species’ distinguished principally by its consistent bulbous augmentation to the spermathecae on either side…here considered equivalent to an allopatric sub-species". Besides, Fig. 1 in Blakemore (2013b) shows two lineages of A. corticis. This is in agreement with our finding (Fig. 3). Sequences of w33 and our specimen with GenBank accession number JX290433 belong to the same group while that of our specimen with GenBank accession number JX290432 belongs to the other (Fig. 3). However, the two specimens with GenBank accession numbers starting with “JX” were found sympatric near a bridge in Fuhsing, Taoyuan, northern Taiwan (Table 1). Sympatry of different lineages has been observed in several peregrine earthworm species (Rota et al. 2018; Taheri et al. 2018; Chang et al. 2024). Similarly, A. corticis also has different lineages which sometimes are in sympatry. Consequently, A. corticis saeseum is not an allopatric sub-species as stated in Blakemore (2013a). Shen (2018) criticized the erection of sympatric subspecies since this common, but harmful practice in earthworm taxonomy ignores the biogeographical connotation of the concept. In addition, specimen with DNA sample labeled as WO4 and the holotype (w33) of A. corticis saeseum belong to the same lineage (Fig. 3), but this specimen, as depicted in Fig. 5 in Blakemore (2013b, p. 105), shows no sign of the bulbous augmentation to the spermathecae. Clearly, this character for distinguishing A. corticis saeseum from the nominal A. corticis is merely individual variation. The name A. corticis saeseum is invalid.

description: Banks in non-metropolitan areas compete in a spatially-differentiated environment. This paper estimates a structural model of the supply and demand of banking services in which pricing power depends on the distance between rival banks. A spatial econometric model finds that approximately 38.0% of economic surplus derives from spatial market power.

description: As with most sectors of the agriculture economy, the U. S. country grain elevator industry has experienced considerable consolidation and concentration. By the same token, the country elevator's customer base (grain producers and landlords) has also changed rather dramatically as grain production takes place on larger and fewer farms. The profitability of operating a country elevator is directly related to the volume of grain the country elevator purchases over the course of a marketing year. Because the basic services offered by country elevators are very similar (purchasing, conditioning and storing grain), country elevators attempt to differentiate themselves from their competition by offering customers a variety of cash grain marketing tools. These tools range from the basic cash forward contracts to minimum price contracts to the so called 'new generation grain marketing contracts'. The primary focus of this paper is to determine the marketing contracts grain elevators offer to their customers and the extent to which these contracts are used by the elevator's customers. Additionally, the types grain contracts offered will be compared to the firm's storage capacity, business organization, size of customer base, geographic location and type of grain purchased.

description: The k-shell decomposition of a random graph provides a different and more insightful separation of the roles of the different nodes in such a graph than does the usual analysis in terms of node degrees. We develop this approach in order to analyze the Internet's structure at a coarse level, that of the "Autonomous Systems" or ASes, the subnetworks out of which the Internet is assembled. We employ new data from DIMES (see http://www.netdimes.org), a distributed agent-based mapping effort which at present has attracted over 3800 volunteers running more than 7300 DIMES clients in over 85 countries. We combine this data with the AS graph information available from the RouteViews project at Univ. Oregon, and have obtained an Internet map with far more detail than any previous effort. The data suggests a new picture of the AS-graph structure, which distinguishes a relatively large, redundantly connected core of nearly 100 ASes and two components that flow data in and out from this core. One component is fractally interconnected through peer links; the second makes direct connections to the core only. The model which results has superficial similarities with and important differences from the "Jellyfish" structure proposed by Tauro et al., so we call it a "Medusa." We plan to use this picture as a framework for measuring and extrapolating changes in the Internet's physical structure. Our k-shell analysis may also be relevant for estimating the function of nodes in the "scale-free" graphs extracted from other naturally-occurring processes.

Neutralizing the Adverse Industry Impacts of CO2 Abatement Policies: What Does It Cost?

description: The most cost-effective policies for achieving CO2 abatement (e.g., carbon taxes) are considered politically unacceptable because of distributional consequences. This paper explores policies designed to address distributional concerns. Using an intertemporal, numerical general equilibrium model of the United States, we examine how efficiency costs change when CO2 abatement policies include elements that neutralize adverse impacts on energy industries. We find that desirable distributional outcomes can be achieved at relatively low cost in terms of efficiency. Without substantial added cost to the overall economy, the government can implement carbon abatement policies that protect profits and equity values in fossil-fuel industries. The key to this conclusion is that CO2 abatement policies have the potential to generate rents that are very large in relation to the potential loss of profit. By enabling firms to retain only a very small fraction of these potential rents, the government can protect firms' profits and equity values. Consequently, the government needs to grandfather only a small percentage of CO2 emissions permits or, similarly, must exempt only a small fraction of emissions from the base of a carbon tax. Each of these government policies involves only a small sacrifice of potential government revenue. Such revenue has an efficiency value because it can be used to finance cuts in pre-existing distortionary taxes. Because these policies give up little of this potential revenue, they involve only a small sacrifice in terms of efficiency. We also find that there is a very large difference between preserving firms' profits and preserving their tax payments. Allowing firms to enjoy a dollar-for-dollar offset to their payments of carbon taxes - for example, through industry-specific cuts in corporate tax rates - substantially overcompensates firms, raising profits and equity values significantly relative to the unregulated situation. This reflects the fact that producers can shift onto consumers most of the burden from a carbon tax. The efficiency costs of such policies are far greater than the costs of policies that do not overcompensate firms.
Fast growth of magnetic fields in galaxy clusters: a self-accelerating dynamo

description: We propose a model of magnetic-field growth in galaxy clusters whereby the field is amplified by a factor of about 10^8 over a cosmologically short time of ~10^8 yr. Our model is based on the idea that the viscosity of the intracluster medium during the field-amplification epoch is determined not by particle collisions but by plasma microinstabilities: these give rise to small-scale fluctuations, which scatter particles, increasing their effective collision rate and, therefore, the effective Reynolds number. This gives rise to a bootstrap effect as the growth of the field triggers the instabilities which increase the Reynolds number which, in turn, accelerates the growth of the field. The growth is explosive and the result is that the observed field strength is reached over a fraction of the cluster lifetime independent of the exact strength of the seed field (which only needs to be above ~10^{-15} G to trigger the explosive growth).

description: We evaluate half-indices of $\mathcal{N}=(2,2)$ half-BPS boundary conditions in 3d $\mathcal{N}=4$ supersymmetric Abelian gauge theories. We confirm that the Neumann boundary condition is dual to the generic Dirichlet boundary condition for its mirror theory as the half-indices perfectly match with each other. We find that a naive mirror symmetry between the exceptional Dirichlet boundary conditions defining the Verma modules of the quantum Coulomb and Higgs branch algebras does not always hold. The triangular matrix obtained from the elliptic stable envelope describes the precise mirror transformation of a collection of half-indices for the exceptional Dirichlet boundary conditions.

Emissions Pricing, Spillovers, and Public Investment in Environmentally Friendly Technologies

description: In a second-best world of below-optimal pollution pricing, the public return to R&D may be greater than under Pigouvian pricing, due to excess benefits of increasing abatement, or it may be lower, since private actors lack the incentives to take full advantage of the new, cleaner technologies. This paper uses a simple model to demonstrate the interaction between environmental policies, R&D externalities, and the social return to innovation. The results indicate that strong public support for innovation is only justified if at least a moderate emissions policy is in place and spillover effects are significant. Furthermore, in most cases, policy constraints that limit regulatory burdens tend to further limit the scope for public support, even when cost reductions allow for more stringent abatement targets. An exception is when knowledge of the policy adjustment process further reduces private innovation incentives.
Differential equations with discrete state-dependent delay: uniqueness and well-posedness in the space of continuous functions

description: Partial differential equations with discrete (concentrated) state-dependent delays in the space of continuous functions are investigated. In general, the corresponding initial value problem is not well posed, so we find an additional assumption on the state-dependent delay function to guarantee the well posedness. For the constructed dynamical system we study the long-time asymptotic behavior and prove the existence of a compact global attractor.

description: Water utilities that rely on surface water may be vulnerable to future droughts and floods, a vulnerability that may be magnified by climate perturbations as well as shorter-term and, in some cases, ongoing changes in the political and regulatory environment in which utilities operate. Unfortunately, day-to-day responsibilities currently occupy most utility operators, leaving little time to plan for inherently uncertain effects. The record of actual responses to past droughts and floods can be illuminating, however, particularly when placed in the context of plausible hydrologic and institutional disruptions. This paper draws on interviews of water utility operators in the northwestern U.S. to highlight opportunities and constraints that water utilities may face vis-à-vis such disruptions. Key considerations affecting vulnerabilities include water rights, institutional barriers to efficient utility operations, hazards management policy, and the fiscal status of utilities.
