description: As a result of Zambia's dependence on copper mining, both the falling world copper price and the possible withdrawal of investment from the mining sector might seriously threaten economic growth and stability. Accordingly, the impact of a 20 percent reduction in world copper prices and a complete collapse of the copper mining sector are modeled using a 1995 computable general equilibrium model for Zambia. Results indicate that the fall in world copper prices will place significant pressure on non- mining exports, with much of the burden of raising foreign exchange falling on the food, beverages and tobacco, and textiles and garment sectors. However, the agricultural and agro-related industries are the most export-responsive (albeit from initially low levels) to the forced depreciation of the currency. The complete collapse of copper mining in Zambia is shown to have a substantial and negative impact on the economy. The fall in production and exports for this important sector leads to a considerable depreciation of the currency in order to fill the resulting gap in foreign earnings. In the short-run, real GDP is reduced by as much as 16 percent. Although the largest increase in exports arises within the food, beverages and tobacco sector, the agricultural and agro-related sectors show considerable potential as sources of foreign exchange earnings. It is found that both the fall in world prices and the reduction in mining output lead to a fall in total real household consumption. However, given that rural households derive a relatively high share of their income from tradable sectors that benefit from the depreciation, the shocks lead to a progressive redistribution of household incomes and consumption. The impact of providing an injection of foreign exchange into the country is found to involve a trade-off between alleviating the negative welfare effects of the copper mining shocks and the provision of incentives for structural adjustment. Furthermore, targeted capital investment in highly export-responsive sectors reduces the necessary depreciation of the real exchange rate, and the need for structural adjustment in other areas of the economy.

description: More than twenty years ago, it was predicted that nuclei can adopt interesting shapes, such as rods or slabs, etc., in the cores of supernovae and the crusts of neutron stars. These non-spherical nuclei are referred to as nuclear "pasta". In recent years, we have been studying the dynamics of the pasta phases using a method called quantum molecular dynamics (QMD) and have opened up a new aspect of study for this system. Our findings include: dynamical formation of the pasta phases by cooling down the hot uniform nuclear matter; phase diagrams in the density versus temperature plane; structural transitions between the pasta phases induced by compression and elucidation of the mechanism by which they proceed. In the present article, we given an overview of the basic physics and astrophysics of the pasta phases and review our works for readers in other fields.

Prophets of rage : expressions of Black nationalism in hip hop
Creators: name: Manyoni, Julian R.
Publisher: name: University of British Columbia
Year: 2009

description: This paper deals with the development of Black nationalist politics in hip hop, focusing primarily on the years up to 1994. This investigation examines two primary strains of nationalist hip hop which emerged in the late 1980s: Afrocentric hip hop nationalism and pro-Black hip hop nationalism. Afrocentric nationalism is based primarily on the notion of Africa as the root of all Black diasporic culture and the idea that a return (either physically or intellectually) to Africa and it's glorious past is the key to develop the Black nation and confront white racism and oppression. Pro-Black hip hop nationalism is expressed by rappers who look to the recent past in order to find their inspiration. They draw their inspiration from the leaders and ideologies of the civil rights struggles of the 1950s, 1960s and 1970s, in particular the 1960s when the movement developed a more militant stance. The paper seeks to examine critically these two forms of hip hop nationalism with special focus on how they envision and represent the Black nation through their art. What becomes apparent is that the main themes in the visual and lyrical imagery tend to be somewhat consistent in both these two forms. In Afrocentric hip hop, the central theme and preoccupation is with location. The literal and symbolic return to the African motherland is what the Black nationalist agenda must be predicated upon, while in pro-Black hip hop the concept of time (and Nation Time) is central. The paper then examines the way in which the above forms of hip hop nationalism use their respective themes, both in terms of effectiveness and coherence, ending in a sharp critique of the almost universally sexist nature of the discourse of nation. Finally, the thesis touches briefly on the next generation (1996-2000) of nation conscious hip hop artists in relation to the artists examined in the main body of the paper and looks at their socio-political ideologies and aims in relation to their predecessors.

description: Over the past four decades almost 400 U.S. counties have persistently experienced poverty rates in excess of 20%. This raises the question of whether poverty-reducing policies should be directed more at helping people or helping the places where they reside. Using a variety of approaches, including geographically weighted regression analysis, we find that local job growth especially reduces poverty in persistent-poverty counties. Findings also show that these counties do not respond more sluggishly to exogenous shocks. Finally, this analysis identifies some key geographic differences among persistent-poverty clusters. Taken together, place-based economic development has a potential role for reducing poverty in these counties.

description: Space and water heating accounts for about 40% of final energy consumption in the European Union and thus plays a key role in reducing overall costs and greenhouse gas emissions. Many scenarios to reach net-zero emissions in buildings rely on electrification, but meeting the heat demand peaks in the winter can be challenging, particularly when wind and solar resources are low. This paper examines how to mitigate space heating demand peaks most cost-effectively in a top-down, sector-coupled model with carbon dioxide emissions constraint to be net-zero. It introduces the first model that co-optimises both supply and efficiency simultaneously including all European countries with hourly resolution. The competition between technologies to address these heating peaks, namely building retrofitting, thermal energy storage and individual hybrid heat pumps with backup gas boilers is examined. A novel thought experiment demonstrates that the level of building renovation is driven by the strong seasonal heat peaks, rather than the overall energy consumption. If all three instruments are applied, total costs are reduced by up to 17%. Building renovation enables the largest benefit with cost savings of up to 14% and allows individual gas boilers to be removed from the energy system without significant higher costs.

description: For a generic $n$-qubit system, local invariants under the action of $SL(2,\mathbb{C})^{\otimes n}$ characterize non-local properties of entanglement. In general, such properties are not immediately apparent and hard to construct. Here we consider certain two-qubit Yang-Baxter operators, which we dub of the `X-type', and show that their eigenvalues completely determine the non-local properties of the system. Moreover, we apply the Turaev procedure to these operators and obtain their associated link/knot polynomials. We also compute their entangling power and compare it with that of a generic two-qubit operator.

description: Solitons are ubiquitous phenomena that appear, among others, in the description of tsunami waves, fiber-optic communication and ultracold atomic gases. The latter systems turned out to be an excellent playground for investigations of matter-wave solitons in a quantum world. This Tutorial provides a general overview of the ultracold contact interacting Bose and Fermi systems in a one-dimensional space that can be described by the renowned Lieb-Liniger and Yang-Gaudin models. Both the quantum many-body systems are exactly solvable by means of the Bethe ansatz technique, granting us a possibility for investigations of quantum nature of solitonic excitations. We discuss in details a specific class of quantum many-body excited eigenstates called yrast states and show that they are strictly related to quantum dark solitons in the both considered Bose and Fermi systems.

description: This study tests for the existence of default and liquidity risk premiums in Farm Credit System bonds. ARCH models are used with over eight years of daily data on yields to maturity of Farm Credit System bonds and U.S. Treasury bonds. Matching five-year maturities for both types of bonds were used. Out data contain evidence of both default and liquidity risk in the spread between the two securities. Elasticity estimates show that the yield spreads are more responsive to default risk than liquidity risk. These sources of risk likely increase the rates agricultural borrowers must pay for loans from the Farm Credit System.

We examine tradeoffs from policies designed to correct an externality in one medium, when there are multiple environmental externalities. We separately and jointly analyze: (a) nitrogen land application restrictions consistent with recently adopted EPA requirements under the Clean Water Act, and (b) hypothetical air quality restrictions under the Clean Air Act, both with and without EQIP payments available to mitigate the costs of complying with nutrient application regulations.
Pion electromagnetic charge radii and rho-meson mass shift at finite density

Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the pion electromagnetic charge radii and mass dropping of the rho meson at finite density. We first calculate the pion charge radii within the framework of the nonlocal chiral quark model from the instanton vacuum both at zero and finite densities. In order to relate the change of the pion charge radius to that of the rho-meson mass at finite density, we employ the vector-meson dominance for the pion electromagnetic form factor. It turns out that the pion charge radius is getting larger as the quark chemical potential increases. As a result, the rho-meson mass falls off as the quark chemical potential grows and is found to be dropped by about 10% at normal nuclear matter density: m*_rho/m_rho ~ 1 - 0.12 mu_B/mu_0, which is compatible to the results of the measurement at the KEK recently.

description: This study uses a generalized Bayesian updating model to estimate the impact of health information appearing in the popular media on the consumption of eggs. The framework permits us to explore the possible effects of several known psychological biases in learning. Generalized Bayesian learning allows media publications to have a decaying effect on behavior. Our primary finding is that health information has a significant impact on U.S. egg consumption. Furthermore, the reaction to health information is found to be temporary. Health information will, on average, decay to a point of unimportance in a matter of a few weeks without a constant and consistent stream of confirming information.

description: This study examined the results of 22 CMIP6 (Coupled Model Inter-comparison Project phase 6) Earth System Model (ESM) simulations for four regions on the Scotian Shelf and Gulf of Maine. A comparison between the historical simulations from the CMIP6 ESMs with observational sea surface and bottom temperature (SST, BT) data demonstrates that the eddy-permitting ESMs do not perform better than coarse-resolution non-eddy permitting models in terms of long-term trends. Eddy-permitting ESMs reduce model SST bias but not BT bias. In general, the 22 CMIP6 ESMs show limited skill for historical BT simulations in these shelf regions. Climate projections under ssp (Shared Socio-economic Pathways)245 and ssp370 for the 2020–2049 period suggest that the largest seasonal SST increase will occur in summer for both the Scotian Shelf and the Gulf of Maine. Under both climate scenarios, the SST of the Scotian Shelf (Gulf of Maine) increases by 1.2–1.8 °C (1.4–1.7 °C) for the 2040–2049 period relative to 1995–2014, and bottom temperature increases by 1.2–1.6°C (1.3–1.4 °C) for the same period. For SST, five models exhibit abnormally warm projections. The ESMs’ performance against observations suggest the SST changes are probably underestimated, while the BT changes are likely overestimated.

description: The problem of quantizing a particle on a 2-sphere has been treated by numerous approaches, including Isham's global method based on unitary representations of a symplectic symmetry group that acts transitively on the phase space. Here we reconsider this simple model using Isham's scheme, enriched by a magnetic flux through the sphere via a modification of the symplectic form. To maintain complete generality we construct the Hilbert space directly from the symmetry algebra, which is manifestly gauge-invariant, using ladder operators. In this way, we recover algebraically the complete classification of quantizations, and the corresponding energy spectra for the particle. The famous Dirac quantization condition for the monopole charge follows from the requirement that the classical and quantum Casimir invariants match. In an appendix we explain the relation between this approach and the more common one that assumes from the outset a Hilbert space of wave functions that are sections of a nontrivial line bundle over the sphere, and show how the Casimir invariants of the algebra determine the bundle topology.

It is shown that, at tree level, the value of the gyromagnetic ratio of the $ρ^+$ is fixed to 2 in a self-consistent effective quantum field theory. Further, the mixing parameter of the photon and the neutral vector meson is equal to the ratio of electromagnetic and strong couplings, leading to the mass difference $M_{ρ^0}-M_{ρ^\pm}\sim 1 {\rm MeV}$ at tree order.

description: Climate change impacts coastal ecosystems through large scale changes in temperature, stratification, circulation and ocean acidification. Here, the potential response of the British Columbia continental margin to climate change is investigated using a regional ocean circulation-biogeochemical model to downscale climate change projections from the Canadian regional and global climate models (CanRCM4/CanESM2) under two Intergovernmental Panel on Climate Change emission scenarios (RCP 4.5 and RCP 8.5). Projections of future physical and biogeochemical conditions for the 2041–2070 period are compared to the recent past (1981–2010). We found an overall annual average warming of >1.6°C in sea surface temperature, increase in stratification in the upper layer, and decrease in surface pH of as much as 0.21. Increasing stratification and changing winds have a limited impact on nitrate availability, phytoplankton biomass and primary production, whilst ocean warming increases primary production by up to 30% in most of the model domain. Increased atmospheric CO2 contributes to acidification over the model domain with a decrease in pH and aragonite saturation (Ωarag) at all depths resulting in an increase of 20 to 32% of the volume of Ωarag ≤1 in the upper 100 m of the continental shelf depending on the climate scenario. Our projected results, therefore, show that future climate change may alter the amount of food available for higher trophic levels and the habitat of benthic species, since bottom waters on the shelf will be undersaturated with respect to aragonite for 2–3 months in mid-summer. Both climate change scenarios results in a similar pattern of changes but projected changes were stronger and more extensive under RCP 8.5 showing the benefit of mitigation efforts in reducing the effect of climate change on marine ecosystem stressors.

description: Previous studies on post-reform market performance of Chinese grain markets have produced mixed results. This paper employs province-level price data to determine if China's food market liberalization policies in the 1990s resulted in interregional rice market integration. Furthermore, this study extends the literature on spatial market integration by augmenting multivariate cointegration modeling techniques with directed acyclic models (DAGs), a recently developed statistical method for analyzing contemporaneous causal relationships. While the empirical results confirm the existence of strong market linkages subsequent to the reforms of the early 19902, the linkages became less as the Chinese government reversed several reform policies in the mid-1990s. Overall, the empirical evidence from this study indicates that China's agricultural market policy reforms have been relatively effective.

description: Myocardial infarction (MI), or commonly known as heart attack, is a life-threatening health problem worldwide from which 32.4 million people suffer each year. Early diagnosis and treatment of MI are crucial to prevent further heart tissue damages or death. The earliest and most reliable sign of ischemia is regional wall motion abnormality (RWMA) of the affected part of the ventricular muscle. Echocardiography can easily, inexpensively, and non-invasively exhibit the RWMA. In this article, we introduce a three-phase approach for early MI detection in low-quality echocardiography: 1) segmentation of the entire left ventricle (LV) wall using a state-of-the-art deep learning model, 2) analysis of the segmented LV wall by feature engineering, and 3) early MI detection. The main contributions of this study are highly accurate segmentation of the LV wall from low-quality echocardiography, pseudo labeling approach for ground-truth formation of the unannotated LV wall, and the first public echocardiographic dataset (HMC-QU)* for MI detection. Furthermore, the outputs of the proposed approach can significantly help cardiologists for a better assessment of the LV wall characteristics. The proposed approach has achieved 95.72% sensitivity and 99.58% specificity for the LV wall segmentation, and 85.97% sensitivity, 74.03% specificity, and 86.85% precision for MI detection on the HMC-QU dataset. *The benchmark HMC-QU dataset is publicly shared at the repository https://www.kaggle.com/aysendegerli/hmcqu-dataset

description: Metaphors We Live By created an immediate stir in 1980, and it continues to spur interest in cognitive linguistics, cognitive stylistics, and metaphor theory. This article uses both collocations and random samples of words used in conceptual metaphors to search for corpus evidence of the pervasiveness of conceptual metaphor that was unavailable to Lakoff and Johnson. Some metaphors, such as TIME IS MONEY, are pervasive in giant natural language corpora. Others, such as MORE IS UP, are frequent in clearly and consciously metaphorical forms, but relatively rare in the basic forms that would clearly show that we use metaphor to understand more abstract concepts in terms of concrete ones. Some, including ARGUMENT IS WAR, that Lakoff and Johnson discuss throughout their book, are poorly represented. Some gaps in evidence probably result from multiple ways of expressing a complex conceptual metaphors, but others suggest that intuitive plausibility is an insecure basis for argument.

description: Grazing permit value supposedly arises as a cost advantage for permit holders. Yet, ranches are overpriced relative to income earning potential. Hedonic models for New Mexico and the Great Basin were used to evaluate permit value. We found less than 16% of the marginal value of grazing permits in New Mexico can be attributed to livestock production, and for Great Basin ranches, estimates indicate none of the value can be assigned to livestock production. Deeded and public land acreages make the ranch bigger and it is the acreage, not the cattle grazing it, that adds the most to ranchland value.

description: Communities throughout the Western United States are challenged by tight water supplies and swelling populations. Information is needed to better develop and target municipal water conservation programs. Significant water savings ranging from 35% to 70% are possible from changes in residential landscaping and improved management of outside watering, which often accounts for more than 50% of total residential water use. This study examines landscape choices of homeowners in three cities in New Mexico in order to identify and measure behavioral factors affecting water conservation. Using survey data, landscape choices are analyzed with a mixed logit model that assesses the effects of landscape and homeowner characteristics on choice probabilities. Model coefficients and implied elasticities indicate that water cost, education, and regional culture are significant determinants of landscape choices. In addition, the results suggest moral suasion can also have a positive influence toward water-conserving landscapes.
Photoevaporation of Grain-Depleted Protoplanetary Disks around Intermediate-Mass Stars: Investigating Possibility of Gas-Rich Debris Disks as Protoplanetary Remnants

description: Debris disks are classically considered to be gas-less systems, but recent (sub)millimeter observations have detected tens of those with rich gas content. The origin of the gas component remains unclear; namely, it can be protoplanetary remnants and/or secondary products deriving from large bodies. In order to be protoplanetary in origin, the gas component of the parental protoplanetary disk is required to survive for $\gtrsim10{\,\rm Myr}$. However, previous models predict $\lesssim 10{\,\rm Myr}$ lifetimes because of efficient photoevaporation at the late stage of disk evolution. In the present study, we investigate photoevaporation of gas-rich, optically-thin disks around intermediate-mass stars at a late stage of the disk evolution. The evolved system is modeled as those where radiation force is sufficiently strong to continuously blow out small grains ($\lesssim 4 {\,\rm μm}$), which are an essential component for driving photoevaporation via photoelectric heating induced by stellar far-ultraviolet (FUV). We find that the grain depletion reduces photoelectric heating, so that FUV photoevaporation is not excited. Extreme-ultraviolet (EUV) photoevaporation is dominant and yields a mass-loss rate of $2$--$5\times10^{-10}(Φ_{\rm EUV}/10^{41}{\,\rm s}^{-1})^{1/2}\,M_\odot\,{\rm yr}^{-1}$, where $Φ_{\rm EUV}$ is the EUV emission rate. The estimated lifetimes of the gas component are $\sim 50 (M_{\rm disk}/10^{-2}\,M_\odot)(Φ_{\rm EUV}/10^{41}\,{\rm s}^{-1})^{1/2}\,{\rm Myr}$ and depend on the ``initial'' disk mass at the point small grains have been depleted in the system. With an order estimation, we show that the gas component can survive for a much longer time around A-type stars than lower-mass stars. This trend is consistent with the higher frequency of gas-rich debris disks around A-type stars, implying the possibility of the gas component being protoplanetary remnants.

description: Inelastic proton scattering via isobaric analog resonances allows to derive rather complete information about neutron particle-hole states. We applied this method to the doubly-magic nucleus 208Pb by measuring angular distributions of 208Pb(p, p') on top of the isobaric analog resonances in 209Bi with the Q3D magnetic spectrograph at München. We identify the six states of the i11/2 f5/2 multiplet and the four states of the i11/2 p3/2 multiplet in the energy range 4.6 MeV < Ex < 5.3 MeV. Firm spin assignments for the ten states are given, some of them new. Additional measurements of the reaction 207Pb(d, p) confirm the fragmented i11/2 p1/2 multiplet.

description: The discovery of the first case of mad cow disease in the United States in 2003 reverberated across the beef and cattle industry. This study employs a general equilibrium model to analyze the potential economic effects of mad cow disease on the beef, cattle, and other meat industries under three scenarios, ranging form most favorable to most pessimistic. The scenario with 90% foreign demand decline and 10% domestic demand reduction generates results consistent with the actual outcomes after the mad cow disease outbreak. Only if domestic demand declines significantly will the economic hardship in the U.S. beef and cattle industry be very large.

description: Thickness loss due to internal corrosion and erosion is a critical issue in ferromagnetic steel structures that can cause catastrophic failures. Ultrasonic thickness gauges are widely used for the detection of wall thickness. Recently permanently installed ultrasonic sensors have become popular for the inspection of areas suspected to undergo wall thickness loss. However, these are limited by the high cost and requirement of coupling agents. To address these problems, a novel cost-effective, and smart corrosion monitor based on the magnetic eddy current technique is developed in this research. The performance and reliability of the monitor to track internal wall thickness loss is tested successfully through accelerated and real-life aging corrosion tests.
Due to the handling and safety issues associated with the powerful magnets in magnetic techniques, a particle swarm-based optimisation method is proposed and validated through two test cases. The results indicate that the area of the magnetic excitation circuit could be reduced by 38% without compromising the sensitivity.
The reliability of the corrosion monitor is improved by utilising the active redundancy approach to identify and isolate faults in sensors. A real-life aging test is conducted for eight months in an ambient environment through an accelerated corrosion setup. The results obtained from the two corrosion monitors confirm that the proposed corrosion monitor is reliable for tracking the thickness loss. The corrosion monitor is found to be stable against environmental variations.
A new in-situ calibration method based on zero-crossing frequency feature is introduced to evaluate the in-situ relative permeability. The thickness of the test specimen could be estimated with an accuracy of ± 0.6 mm.
The series of studies conducted in the project reveal that the magnetic corrosion monitor has the capability to detect and quantify uniform wall thickness loss reliably.

description: Release of a genetically modified (GM) crop variety would lower prices of competing pesticides used on conventional varieties. This causes an increase in surplus for those farmers who adopt the GM variety, as well as for those who plant the conventional variety. A Cournot model was developed to determine the equilibrium quantities of conventional pesticides. A market with conventional wheat was compared to a market with both conventional and GM wheat varieties to identify price decreases of the conventional pesticide as a result of the GM trait introduction.

Material examined
ESTONIA • 1 spec.; Hosholm shore; Adila Formation, Pirgu Regional Stage; TUG 939-78.
Description
The specimen is a ca 39 mm long, 18–20 mm high, orthoconic fragment (angle of expansion 3°) of a phragmocone with well-preserved shell sculpture. The conch cross section is slightly deformed. The conch is annulated with ca four annulations in a distance equal to the corresponding conch cross section. The annulations are directly transverse. The conch is ornamented with ca 60 fine longitudinal lirae around the circumference and subordinate transverse growth lines or lirae, producing a reticulate pattern (ca 10 transverse lirae per annulation). The septa are only partially preserved, the siphuncle and septal necks are not preserved. The sutures are positioned in the troughs of the annulations and are directly transverse parallel to the annulations.
Remarks
The finely reticulate ornamentation and the general conch shape of this specimen is similar to other species assigned to P. senckenbergi. It differs from the latter in having a wider spacing of its longitudinal lirae (1 mm and 60 lirae around circumference versus five to seven lirae per mm in P. senckenbergi). The fragmentary preservation of the internal characters leaves the genus level determination questionary because a similar fine reticulate ornamentation is known from Anaspyroceras, and Gorbyoceras (see e.g., Flower 1943b). Possibly, the specimen belongs to the same species as a specimen described by Strand (1934: 21) under G. clathratoannulatum, also ornamented with ca 60 longitudinal lirae.

description: Feeder animal prices depend on fed animal prices, the biological growth technology, and feed costs. In addition, daily maintenance costs can be avoided through accelerated feeding. These observations allow us to model optimal feeding under equilibrium feeder animal pricing. Our model enables a better understanding of regulation in feedstuff markets. The feeder animal price-weight schedule is likely decreasing and convex in weight. Prices for animals with better growth potential should be less sensitive to feed and fed animal prices. Prices for lighter animals should be more sensitive to these prices. Regression analyses on Southern Great Plains cattle prices provide support for this model.

description: While during inflation a phase of increasing gauge coupling allows for a scale-invariant hyperelectric spectrum, when the coupling decreases a flat hypermagnetic spectrum can be generated for typical wavelengths larger than the effective horizon. After the gauge coupling flattens out the late-time hypermagnetic power spectra outside the horizon in the radiation epoch are determined by the hyperelectric fields at the end of inflation whereas the opposite is true in the case of decreasing coupling. Instead of imposing an abrupt freeze after inflation, we consider a smooth evolution of the mode functions by positing that the gauge couplings and their conformal time derivatives are always continuous together with the background extrinsic curvature. The amplified gauge power spectra are classified according to their transformation properties under the duality symmetry. After clarifying the role of the comoving and of the physical spectra in the formulation of the relevant magnetogenesis constraints, the parameter space of the scenario is scrutinized. It turns out that a slightly blue hyperelectric spectrum during inflation may lead to a quasi-flat hypermagnetic spectrum prior to matter radiation equality and before the relevant wavelengths reenter the effective horizon. In this framework the gauge coupling is always perturbative but the induced large-scale magnetic fields can be of the order of a few hundredths of a nG and over typical length scales between a fraction of the Mpc and $100$ Mpc prior to the gravitational collapse of the protogalaxy.

description: This paper investigates the effect of information on respondent's choices in an internet survey for measuring the value of water quality improvements in Deckers Creek (DC) watershed in Monongalia and Peterson Counties of West Virginia, USA. A multiattribute, choice experiment and multinomial logit (MNL) models are used in estimating the marginal utilities of restoring the three attributes of DC: aquatic life, swimming safety, and scenic quality. Response times serve as proxy variables regarding whether respondents read or did not read all the information provided in the survey. Response times fell quickly, but then tapered off as they progressed through the various sections of the survey. Results show that the estimated coefficients of subsamples, read and did not read all the information, were statistically different from each other. Based on log likelihood tests of MNL models, two subsamples of the survey population (read and did not read all information) were found to be from different populations. Estimates of marginal utilities reveal that respondents value aquatic life restoration the highest, followed by scenic quality restoration. Average compensating variation estimates for full restoration of the aquatic life and scenic quality attributes are $9 and $ 6 per month per household, respectively, when the subsamples are pooled. However, the individual subsamples resulted in $5 per month for aquatic life and $3 per month for scenic quality for respondents that read the information, while respondents that did not read the information resulted in statistically higher estimates of $16 and $12, respectively. While respondents' motives for not reading the resource information provided is uncertain, results show their values for watershed restoration are substantially higher than respondents that read the information.
