Subjects: Environmental Economics and Policy

description: Using farmer responses to contingent valuation method (CVM) survey data in combination with actual market data from four watershed regions in the United States, this study estimates the minimum incentives payments a farmer would accept in order to adopt more environmentally friendly "best management practices" (BMPs). Combining actual market data with the CVM data adds information to the analysis, thereby most likely increasing the reliability of the results compared to analyzing the contingent behavior survey response data only. Given the decision to adopt, the article also presents a pooled model for the number of acres enrolled in the BMPs as a function of the incentive payments. Adoption rates predicted with the combination data model are significantly higher over a wide range of offers than those predicted using the traditional discrete choice analysis with the hypothetical data only. Hence, using the traditional CVM analysis results to determine payments to attain a given level of adoption may result in overpayment.

description: Based on the observation that the exterior space-times of Schwarzschild-type solutions allow two symmetric slicings, a static spherically symmetric one and a timelike homogeneous one, modifications of gravitational dynamics suggested by symmetry-reduced models of quantum cosmology can be used to derive corresponding modified spherically symmetric equations. Generally covariant theories are much more restricted in spherical symmetry compared with homogeneous slicings, given by $1+1$-dimensional dilaton models if they are local. As shown here, modifications used in loop quantum cosmology do not have a corresponding covariant spherically symmetric theory. Models of loop quantum cosmology therefore violate general covariance in the form of slicing independence. Only a generalized form of covariance with a non-Riemannian geometry could consistently describe space-time in models of loop quantum gravity.

description: Nitrogen vacancy (NV) centers in diamonds is a promising system for quantum information processing and quantum sensing, and the control of the quantum state is essential for practical applications. In this study, we demonstrate a control of all the three transitions among the ground state sublevels of NV centers by applying external magnetic driving fields. To address the states of a specific NV axis among the four axes, we apply a magnetic field orthogonal to the NV axis. We control two transitions by microwave pulses and the remaining transition by radio frequency pulses. In particular, we investigate the dependence of Rabi oscillations on the frequency and intensity of the radio frequency pulses. Our results pave the way for a novel control of NV centers for the realization of quantum information processing and quantum sensing.

description: Cancers remain one of the leading causes of death in the world. However, known conventional cancer medicines remain scarce, expensive and out of reach to many patients. To provide an alternative for the expensive therapies, plants are proving to have potential to lead to the development of more drugs against cancers. In this work, we aimed at isolating possible pure compounds from Eichhornia crassipes roots and leaves, examining their prospects to be developed into oral drugs by looking at their chemical properties and also exploring their cytotoxic activities. A total of 12 isolates (A-L) were obtained and examination of their UV and mass profiles on LCMS and cytotoxicity on human cell lines. Compound C was the most active against MCF-7 cell lines (3.08 ± 0.06 µg/ml) and (3.92 ± 0.06 µg/ml) against HepG2. The standard drug, doxorubicin, had an IC50 value of 0.29 ± 0.05 µg/ml against MCF-7 and 0.33 ± 0.04 µg/ml against HepG2 cell lines. UV results from the LCMS chromatograms showed that some active isolates do not possess the chemistry suitable to be developed into oral drugs as they are while others that are not as potent possess very good drug-like chemistry. We therefore conclude that there is need for drug developers to consider chemical properties and medicinal chemistry prospects of active isolates/compounds through rational optimization in plant-based drug discovery. Eichhornia crassipes should be considered as a cheap source of potential drug hits against cancers.

description: This limited analysis resulted from a request by the Nebraska National Forest to provide some economic estimates to the value of changes in forage availability that would result from three proposed levels of rodenticide use in the management of black-tailed prairie dogs (BTPD) on the Nebraska National Forest (NNF) and associated units managed by NNF (i.e. Buffalo Gap National Grasslands, Ft. Pierre National Grasslands in South Dakota, and the Oglala National Grasslands in Nebraska.) The values of changes in forage availability were determined based on three alternatives of rodenticide use. These alternatives include: (1) limit use of rodenticides to only protect public health & safety and maintain facilities; (2) maintain a 1 mile buffer zone to prevent encroachment of BTPDs onto adjacent private or tribal agricultural land; and (3) provide a 1 mile buffer zone in the Conata Basin area (under specific conditions), ¼ mile buffer on the Ft. Pierre National Grasslands, and ½ mile buffer everywhere else. Two levels of estimates were provided by the NNF estimating the change in available forage from BTPD expansion given: (1) normal to above normal precipitation, and (2) below normal precipitation; over a 10 year period. Forage change estimates where provided by the NNF in pounds and in terms of Animal Unit Months (AUMs) of grazing. A 3 year average of hay prices ($70.00/ton) and AUM rates ($16.63/AUM) from the SD Agricultural Statistic Service were used to value the change in forage availability. The results of this analysis showed that under Alternative 1, the value of the change in forage availability in pounds range from loss of $79,870 to $212,065 from the low to high projected expansion of BTPD colonies. In terms of AUM value this loss ranged from $48,686 to $129,208. Under Alternative 2, the value of the change in forage availability in pounds range from a gain of $59,185 to $62,860 from the low to high projected decrease in BTPD colonies. In terms of AUM value this gain ranged from $36,029 to $38,274. With respect to Alternative 3, there was an overall gain in value from the reduction of BTPD colonies. In terms of pounds of available forage this value ranged from $9,065 to $23,835 and in AUM value from $5,506 to $14,521. Only the Ft. Pierre National Grassland had a loss of value under the low BTPD expansion estimate of $2,065 in the value per ton and $1,264 in the AUM value under Alternative 3.

description: Considering the GAIA data for {$\approx 10^6$} stars around the {barycenter,} we estimate the fractal dimension for different regions in the Milky Way. Then we use those fractal dimensions to calculate the gravitational potential considering the medium as a continuous fractal. Finally, {we use the gravitational potential to infer} the circular velocity {and adjust} rotation curves in the Milky Way. {For this,} we use two numerical models, the first considering uniform density and a second more realistic of a bulge and a disk. In none of these models we consider dark matter. We study their validity comparing them with circular speed data from the Milky Way.

description: We propose a simple scaling ansatz for the full replica symmetry breaking solution of the Sherrington-Kirkpatrick model in the low energy sector. This solution is shown to become exact in the limit x->0, x>>T of the Parisi replica symmetry breaking scheme parameter x. The distribution function P(x,y) of the frozen fields y has been known to develop a linear gap at zero temperature. We integrate the scaling equations to find an exact numerical value for the slope of the gap to be 0.3014046... We also use the scaling solution to devise an inexpensive numerical procedure for computing finite timescale (x=1) quantities. The entropy, the zero field cooled susceptibility and the local field distribution function are computed in the low temperature limit with high precision, barely achievable by currently available methods.

description: We introduce an all-versus-nothing proof of impossibility of Einstein-Podolsky-Rosen's local elements of reality for two photons entangled both in polarization and path degrees of freedom, which leads to a Bell's inequality where the classical bound is 8 and the quantum prediction is 16. A simple estimation of the detection efficiency required to close the detection loophole using this proof gives eta > 0.69. This efficiency is lower than that required for previous proposals.

description: Major agri-environmental programs tried in the United Kingdom (UK)since the mid-1980s are examined in this report. Special attention is given to the Environmental Sensitive Areas (ESA) scheme, the Countryside Stewardship Scheme (CSS), and schemes to promote organic agriculture-first the Organic Aid Scheme and, following that, the Organic Farming Scheme. Several major studies and reviews of these and other agri-environmental schemes in England, Scotland, and Wales have been conducted in recent years. These studies and reviews are drawn upon to examine both the successes and shortcomings of various schemes in drawing farmers into more environmentally sound farming practices and systems. In conducting this review and examination, primary attention is given to farmers' income, risk reduction, and stewardship goals. Contextual factors given special attention include the following: prices and access to markets; technologies; the structure of agriculture; and social and human capital. Lessons for future agri-environmental strategies in the UK, elsewhere in Europe, and the United States are derived from this review. The emerging 'multifunctionality' approach to agricultural policy is emphasized. Among the lessons are ones dealing with: legume-based rotations in arable areas; financial assistance to organic farmers beyond the transition period; continued reform of the European Union's Common Agricultural Policy; possible merging of the ESA scheme and the CSS; extension/technical assistance nstitutions and strategy; and social and human capital for environmental change. Several issues and challenges in greatly expanding agri-environmental policies and making them more effective in the future are analyzed and explained. Those issues and challenges pertain to: the compatibility of production support and stewardship support policies; balancing stewardship support and 'environmental compliance'; opportunities for programs to contribute jointly to social and stewardship objectives; the compatibility of World Trade Organization rules with stewardship schemes; capitalization of scheme benefits into land values; how to gain from bottom-up planning and subsidiarity; and stewardship payments for farmers already practicing good stewardship.

description: We report the discovery of millisecond pulsations from the low-mass X-ray binary HETE J1900.1-2455 which was discovered by the detection of a type I X-ray burst by the High Energy Transient Explorer 2 (HETE-2). The neutron star emits coherent pulsations at 377.3 Hz and is in an 83.3 minute circular orbit with a companion with a mass greater than 0.016 solar masses and likely less than 0.07 solar masses. The companion star's Roche lobe could be filled by a brown dwarf with no need for heating or non-standard evolution. During one interval with an unusually high X-ray flux, the source produced quasiperiodic oscillations with a single peak at 883 Hz and on subsequent days, the pulsations were suppressed. We consider the distribution of spin versus orbital period in neutron star low-mass X-ray binaries.

description: Gas-filled hollow-core photonic crystal fiber (PCF) is used for efficient nonlinear temporal compression of femtosecond laser pulses, two main schemes being direct soliton-effect self-compression, and spectral broadening followed by phase compensation. To obtain stable compressed pulses, it is crucial to avoid decoherence through modulational instability (MI) during spectral broadening. Here we show that changes in dispersion due to spectral anti-crossings between the fundamental core mode and core wall resonances in anti-resonant-guiding hollow-core PCF can strongly alter the MI gain spectrum, enabling MI-free pulse compression for optimized fiber designs. In addition, higher-order dispersion can introduce MI even when the pump pulses lie in the normal dispersion region.

description: With the advent of data-driven statistical modeling and abundant computing power, researchers are turning increasingly to deep learning for audio synthesis. These methods try to model audio signals directly in the time or frequency domain. In the interest of more flexible control over the generated sound, it could be more useful to work with a parametric representation of the signal which corresponds more directly to the musical attributes such as pitch, dynamics and timbre. We present VaPar Synth - a Variational Parametric Synthesizer which utilizes a conditional variational autoencoder (CVAE) trained on a suitable parametric representation. We demonstrate our proposed model's capabilities via the reconstruction and generation of instrumental tones with flexible control over their pitch.

description: There is a growing interest in utilizing the distinctive material properties of organic semiconductors for spintronic applications. Here, we explore injection of pure spin current from Permalloy into a small molecule system based on dinaphtho[2,3-b:2,3-f]thieno[3,2-b]thiophene (DNTT) at ferromagnetic resonance. The unique tunability of organic materials by molecular design allows us to study the impact of interfacial properties on the spin injection efficiency systematically. We show that both, spin injection efficiency at the interface as well as the spin diffusion length can be tuned sensitively by the interfacial molecular structure and side chain substitution of the molecule.

description: Using responses from a mail survey conducted among 203 South Dakota grain elevator managers in 2002, we analyzed the degree to which their elevators were prepared to segregate non-transgenic from commodity grains. Results showed four percent of the managers expected their own, and ten percent expected a competing elevator be dedicated to handling only non-transgenic or identity preserved grains within five years. Only four and one percent of the elevators handled non-transgenic corn and soybeans, respectively, and only one percent participated in identity preserved grains. One in five elevator managers in the state reported having tested corn for transgenic material, and none of the respondents conducted any genetic testing for soybeans in 2001. Further, 17 and two percent reported having buyers inquire about segregated non-transgenic or identity preserved corn, and such soybeans, respectively. Among those handling corn (soybeans), 29 (30) percent was familiar with the non-transgenic corn (soybean) market and 53 (58) percent was willing to participate in these markets at an average premium of 28 (37) cents per bushel. One in five elevators are able to participate in segregating non-transgenic and commodity grains without additional capital outlays. Thus, if a sizable demand for non-transgenic grains develops, the South Dakota grain handling industry appears ready to deal with it.

In this study, we use photoemission spectroscopy and quantum transport to elucidate the topology of the room temperature magnet Co$_2$MnGa. We observe sharp bulk Weyl fermion line dispersions indicative of nontrivial topological invariants present in the magnetic phase. On the surface of the magnet, we observe electronic wave functions that take the form of drumheads, enabling us to directly visualize the crucial components of the bulk-boundary topological correspondence. By considering the Berry curvature field associated with the observed topological Weyl fermion lines, we quantitatively account for the giant anomalous Hall response observed in our samples. Our experimental results suggest a rich interplay of strongly correlated electrons and topology in this quantum magnet.

description: The polarized lepton pair forward-backward asymmetries in (B -> rho l^+ l^-) decay using a general, model independent form of the effective Hamiltonian is studied. The general expression for nine double-polarization forward-backward asymmetries are calculated. The study of the forward-backward asymmetries of the doubly-polarized lepton pair proves to be very useful tool in looking for new physics beyond the standard model.

description: This study examined the perspectives of parents from South Asian diaspora in the UK and early years practitioners regarding the construction of identities of children of South Asian heritage. Berry’s (1997, 2002, 2009) model of acculturation was used as a lens to examine how parents make sense of their and their children’s experiences in the new social and cultural context. The qualitative research data derived from 26 focus groups with 134 parents and 82 practitioners.Findings suggested that the wishes and concerns of South Asian migrant parents regarding how they perceive and want their child’s multiple identities to be constructed is unacknowledged by practitioners. The study revealed that the most significant barrier for this was the lack of dialogue between parents and practitioners.The research findings led me to explore and create a strategy for promoting dialogue and addressing the asymmetrical relationship between parents and practitioners. Homi Bhabha’s (1994) concept of the Third Space and Paulo Freire’s Pedagogy of the Oppressed (1989) offered me a theoretical frame for creating the Cultural Circles strategy for negotiating spaces in which symmetrical dialogue can take place. The metaphor of the Third Space highlighted how families from South Asian diaspora could negotiate their children’s bicultural or hybrid identities in this space, offering a rich mix of associations, emotions, experiences, and meanings that acknowledged the profound complexities of multiple rather than fixed identities among these families and their children.Previous researchers have reported an ‘identity crisis’ during teenage years in which adolescents of migrant parents struggle to balance their heritage and host identities (Erikson, 1970; Robinson, 2009). This thesis demonstrated how early childhood practitioners could play a critical role in supporting both heritage and emerging identities in children of South Asian heritage to prevent their ‘identity crisis’ later in life.

description: A fluctuation theorem is proved for the macroscopic currents of a system in a nonequilibrium steady state, by using Schnakenberg network theory. The theorem can be applied, in particular, in reaction systems where the affinities or thermodynamic forces are defined globally in terms of the cycles of the graph associated with the stochastic process describing the time evolution.

‘City of History and Progress’: Heritage and urban development in Leicester 1934 to 2010

description: Using Leicester as a case study, this thesis examines how the city’s past, in the form of its streets and buildings, has been recognised and utilised by a range of actors between the 1930s and the first decade of the twenty-first century. Through the examination of how this industrial Midlands city balanced the co-existence of its heritage and its progress, in the form of urban development, it shows how cities have reflected and responded to changes in policies and public opinion towards the historic built environment from the 1930s to the 2000s. These changes in public attitudes, government policies and funding sources are evidenced through a chronological examination of planning approaches and interventions that have contributed to the conservation of Leicester’s historic urban fabric. Some interventions were driven by heritage-specific objectives, like the development of conservation areas from the late 1960s, while others were not heritage-specific and were driven by priorities and funding for housing or regeneration. Through the regeneration of the St George’s area of the city the thesis demonstrates how local authorities needed to address the priorities of regional, national and European agencies in order to access funding to provide new uses for former industrial areas. This thesis also shows how heritage was used to promote the city to visitors and businesses from the 1930s to the 1960s. Through an examination of the images used in that promotion, it highlights the difference between the historic monuments and buildings formally recognised and protected by the listing system, and the historic urban fabric valued locally. The thesis demonstrates the contribution of local people in conserving their city through participation in planning the General Improvement Area of Clarendon Park, involvement in specific conservation battles in the city, and efforts to secure listing status and statutory protection for buildings as part of European Architectural Heritage Year.
On the Improvement of the High Temperature Oxidation Performance of Niobium Silicide-based Alloy Systems Produced by Laser Additive Manufacture

description: There has been significant research into improving the efficiency of aerospace engines. This can be done by increasing the operating temperature of the turbine section of the engine. Turbine blades can be subjected to temperatures <1350°C. Nickel-based superalloys are the current material, but they are at the limits of their temperature capability.Niobium silicide alloys offer a potential route to higher engine efficiencies. Binary Nb-Si alloys possess a solidus temperature near 1900°C. However, to operate in such temperatures the alloy needs to be able to resist high temperature oxidative attack. Nb-Si alloys have not proven to be resistant to oxidation thus far. If they are to replace Ni-based superalloy they will need improved oxidation performance. Processing these alloys is also challenging as the high temperature melt reacts with traditional mould materials.This work aimed to improve the oxidation resistance of a MASC-based alloy by using uncommon elemental additions. Manufacture of the alloys in this study was done using direct metal deposition (DMD), a form of laser additive manufacture. This eliminates the need for a mould. DMD is relatively untested, so this study investigated the properties of an MASC-based Nb-Si alloy after creation by DMD. An assessment of macro-segregation was performed, which found no evidence this phenomena.The alloy then underwent oxidation tests, comparing the results to literature source where arc vacuum melting was used. DMD marginally improved oxidation properties and changed the mechanism at 800°C. This study found a parabolic regime, followed by a linear regime. With the viability of DMD confirmed, additions of Zr (with Y) and Ta were added. At 1 at%, Zr showed minor improvements at 800°C in the linear regime. 2 at% Ta resulted in markedly improved parabolic rate constants at 1200°C. Additions of Ta show great potential in improving the oxidation resistance of Nb-Si alloys.

description: The high-frequency peaked BL Lac PKS 2005-489 (z=0.071) was observed in 2003 and 2004 with the H.E.S.S. stereoscopic array of imaging atmospheric-Cherenkov telescopes in Namibia. A signal was detected at the 6.7 sigma level in the 2004 observations (24.2 hrs live time), but not in the 2003 data set (27.3 hrs live time). PKS 2005-489 is the first blazar independently discovered by H.E.S.S. to be an emitter of VHE photons, and only the second such blazar in the Southern Hemisphere. The integral flux above 200 GeV observed in 2004 is (6.9 +/- 1.0 +/- 1.4) x 10$^{-12}$ cm$^{-2}$ s$^{-1}$, corresponding to ~2.5% of the flux observed from the Crab Nebula. The 99% upper limit on the flux in 2003, I(>200 GeV) < 5.2 x 10$^{-12}$ cm$^{-2}$ s$^{-1}$, is smaller than the flux measured in 2004, suggesting an increased level of activity in 2004. However, the data show no evidence for significant variability on any time scale less than a year. An energy spectrum is measured and is characterized by a very soft power law (photon index = 4.0 +/- 0.4).

Role of Hanna Glawari in Franz Lehar’s The Merry Widow
Creators: name: Christie, Sheila Marjorie
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is submitted in partial fulfilment of the requirements for the degree of Master of Music in opera performance. The thesis is the operatic role of Hanna Glawari in Franz Lehar's The Merry Widow. The Merry Widow is based upon the play L'attache by Henri Meilhac, the action of which takes place at the German Embassy in Paris. The Viennese librettists Victor Leon and Leo Stein selected Meilhac's comedy as the basis for their operetta libretto that was later set to music by Franz Lehar. The librettists made many changes to the play, most importantly, the locale. They transformed the German Embassy into the legation of a small Balkan principality. For their model, they used the nation of Montenegro, on the southern boundary of the Austro-Hungarian monarchy. Several connections were made to Montenegro, for example the name of the lead male part Danilo was taken from Montenegro's hereditary prince, and the librettists stipulated that the costumes were to be in the style of Montenegro. However, to avoid scandal and legal problems, Stein and Leon re-christened their operetta land as the fictitious nation of Pontevedro. The Merry Widow was given its first performance at Vienna's Theater an der Wien on December 30, 1905. The action of the operetta is set in Paris in 1905. Hanna Glawari, the heroine of this German operetta, is a young widow whose late husband (a wealthy banker) left her a fortune totalling fifty million francs. Mrs. Glawari is a Pontevedrian visiting the Pontevedrian Embassy in Paris, where she hopes to expand her horizons and possibly remarry. Before her arrival in Paris, the Baron Zeta receives strict orders from Emperor Niklaus of Pontevedro to keep Mrs. Glawari's fortune in their own country, for if she were to marry a Parisian, Pontevedro would become bankrupt. What follows is an entertaining mix of zany antics, mistaken identities, intrigues, reunited lovers, and some of the most beautiful music and Viennese Waltzes ever written. In the end, Pontevedro and Hanna win with the announcement of her engagement to a formerly estranged lover Count Danilo Danilowitch. All are happy and the operetta ends on a high note (pardon the pun)!
Star Formation Efficiency in Driven, Supercritical, Turbulent Clouds

description: We present measurements of the star formation efficiency (SFE) in 3D numerical simulations of driven turbulence in supercritical, ideal-MHD, and non-magnetic regimes, characterized by their mean normalized mass-to-flux ratio $μ$, all with 64 Jeans masses and similar rms Mach numbers ($\sim 10$). In most cases, the moderately supercritical runs with $μ= 2.8$ have significantly lower SFEs than the non-magnetic cases, being comparable to observational estimates for whole molecular clouds ($\lesssim$ 5% over 4 Myr). Also, as the mean field is increased, the number of collapsed objects decreases, and the median mass of the collapsed objects increases. However, the largest collapsed-object masses systematically occur in the weak-field case $μ= 8.8$. The high-density tails of the density histograms in the simulations are depressed as the mean magnetic field strength is increased. This suggests that the smaller numbers and larger masses of the collapsed objects in the magnetic cases may be due to a greater scarcity and lower mean densities (implying larger Jeans masses) of the collapse candidates. In this scenario, the effect of a weak field is to reduce the probability of a core reaching its thermal Jeans mass, even if it is supercritical. We thus suggest that the SFE may be monotonically reduced as the field strength increases from zero to subcritical values, rather than there being a discontinuous transition between the sub- and supercritical regimes, and that a crucial question to address is whether the turbulence in molecular clouds is driven or decaying, with current observational and theoretical evidence favoring (albeit inconclusively) the driven regime.
