description: Public lands in Southern and Central Appalachia (SCA) available for outdoor recreational pursuits are limited relative to the rest of the county. This study identifies factors that encourage private land owners to permit public access to their land for recreational purposes and determines how much acreage would be offered in the Southern and Central Appalachia region. The Tobit and Heckman’s sample selection models suggest that the probability of offering land to the public is correlated with the number of acres offered. Having acreage suited for recreation is a positive determinant of acres leased but attributes developed by the landowner act as a disincentive. Type of recreational activity has no effect on the landowner’s decision and the supply of recreational acreage is inelastic with respect to price.

description: Accurately forecasting volatility at distant horizons is critical for managing long-term risk in agriculture. Given the poor performance of GARCH-type models at long-term volatility forecast, we develop a risk-adjusted implied volatility, which adjust the risk-neutral implied volatility by correctly accounting for the volatility risk premium. The paper evaluates the performance of the new implied volatility in the corn futures market relative to two alternative forecasts- a three-year moving average forecast and a naïve forecast. The finding from the study is that the new implied volatilities have at least as well as or stronger predictive power than alternative predicting approaches.
Income support programs and labour market behaviour in Canada
Creators: name: Whelan, Stephen Patrick
Publisher: name: University of British Columbia
Year: 2009

description: Income support programs constitute an integral component of modern labour markets and represent significant fiscal commitments on the part of governments. This thesis examines two key income support programs in Canada and their impact on labour market outcomes, namely employment insurance (EI) and social assistance (SA). Together expenditures on EI and SA represented approximately 2 per cent of Canadian GDP in 1998-99 and influenced a range of labour market decisions relating to labour force participation, employment and unemployment spells. The analysis in this thesis provides new evidence on the role of the EI and SA programs on labour market outcomes by examining the interface between the programs and labour market behaviour. An analysis of the take-up of SA amongst a sample of SA eligible individuals is also undertaken that provides new evidence on the determinants of participation in the SA program in Canada. The analysis in this thesis uses the 1997 Canadian Out of Employment Panel dataset, a unique dataset that provides detailed information on the use of income support programs and employment patterns, and detailed information on a rich set of personal and household characteristics. The approach adopted in this thesis is to use a generalized probability transition model to examine the nature of the interface between income support programs and their effect on labour market outcomes. This approach allows the implications of changes in either program for use of the other program, and overall labour market outcomes, to be identified. The analysis of the SA take-up decision uses a discrete choice framework that explicitly takes account of the potential endogeneity of benefit levels available to the individual. A number of conclusions can be drawn from the analysis undertaken in this thesis. First, when the generosity of the SA program is reduced, individuals decrease use of both the SA and EI programs. Conversely, reducing the generosity of the EI program results in an increase in the use, albeit relatively small, of the SA program. The results of the analysis of the take-up decision of the SA program point to the key role of benefit levels and previous use of the program as determinants of the likelihood that an individual takes up SA.

description: The aim of this work is to establish a linear instability result of stationary, kink and kink/anti-kink soliton profile solutions for the sine-Gordon equation on a metric graph with a structure represented by a $\mathcal Y$-junction. The model considers boundary conditions at the graph-vertex of $δ$-interaction type, or in other words, continuity of the wave functions at the vertex plus a law of Kirchhoff-type for the flux. It is shown that kink and kink/anti-kink soliton type stationary profiles are linearly (and nonlinearly) unstable. For that purpose, a linear instability criterion that provides the sufficient conditions on the linearized operator around the wave to have a pair of real positive/negative eigenvalues, is established. As a result, the linear stability analysis depends upon of the spectral study of this linear operator and of its Morse index. The extension theory of symmetric operators, Sturm-Liouville oscillation results and analytic perturbation theory of operators are fundamental ingredients in the stability analysis. A comprehensive study of the local well-posedness of the sine-Gordon model in $\mathcal E(\mathcal Y) \times L^2(\mathcal{Y})$ where $\mathcal E(\mathcal Y) \subset H^1(\mathcal{Y})$ is an appropriate energy space, is also established. The theory developed in this investigation has prospects for the study of the instability of stationary wave solutions of other nonlinear evolution equations on metric graphs.

description: We study the thermal production of kaons in hot and dense symmetric and asymmetric hypernuclear matter in the context of the modified quark-meson coupling model. All the baryon species and kaons are treated as MIT bags that interact with each other via the scalar mesons $σ,σ^*$ and the vector mesons $ω,ϕ$ as well as the isovector meson $ρ$. Furthermore, in our calculations, we use realistic sets of hyperon-hyperon (or $YY$) interactions based on several versions of Nijmegen core potential models. We consider a system of strange hadronic matter and kaons but with zero total net strangeness of the system and conserved small negative fraction of the isospin-charge. We find strange baryons as well as kaons are produced abundantly when the temperature increases and approaches the critical temperature for the phase transition to the quark-gluon plasma. Our results show that the kaons are produced only thermally in the symmetric and asymmetric hypernuclear matter and there is no signature for the onset of kaon condensation in the relativistic heavy ions collision. The kaons appear in the system only by thermal production. However, when the system cools down strange hadrons could survive.

description: Recent advances in nanofluidics have allowed exploration of ion transport down to molecular scale confinement, yet artificial porins are still far from reaching the advanced functionalities of biological ion machinery. Achieving single ion transport that is tuneable by an external gate -- the ionic analogue of electronic Coulomb blockade (CB) -- would open new avenues in this quest. However, an understanding of ionic CB beyond the electronic analogy is still lacking. Here we show that the many-body dynamics of ions in a charged nanochannel result in a quantised and strongly nonlinear ionic transport, in full agreement with molecular simulations. We find that ionic CB occurs when, upon sufficient confinement, oppositely charged ions form 'Bjerrum pairs', and the conduction proceeds through a mechanism reminiscent of Onsager's Wien effect. Our findings open the way to novel nanofluidic functionalities, such as an ionic-CB-based ion pump inspired by its electronic counterpart.

description: Index insurance has been promoted as a cost-effective risk management alternative for agricultural producers in developing countries. In this paper, we ask whether spatially separated weather variables commonly used in index insurance design, such as rainfall at different weather stations within a defined geographical area, are more highly correlated at the tails. As a case study, we assess the degree of tail dependence exhibited by Iowa June county-level rainfalls using copulas. We search among various candidate bivariate copulas and, using goodness-of-fit for copulas, attempt to identify the copula structures that best explain the nature of dependence among rainfalls in adjacent counties. Our results provide strong evidence that lower tail dependence exists in most of adjacent county-level rainfalls in Iowa. The results also suggest that patterns of tail dependence differ across counties.

description: We study the Stark effect for an exciton confined in a pair of vertically coupled quantum dots. A single-band approximation for the hole and a parabolic lateral confinement potential are adopted which allows for the separation of the lateral center-of-mass motion and consequently for an exact numerical solution of the Schrödinger equation. We show that for intermediate tunnel coupling the external electric field leads to the dissociation of the exciton via an avoided crossing of bright and dark exciton energy levels which results in an atypical form of the Stark shift. The electric-field-induced dissociation of the negative trion is studied using the approximation of frozen lateral degrees of freedom. It is shown that in a symmetric system of coupled dots the trion is more stable against dissociation than the exciton. For an asymmetric system of coupled dots the trion dissociation is accompanied by a positive curvature of the recombination energy line as a function of the electric field.

description: There is immense interest in how the local environment influences the electronic structure of materials at the single layer limit. We characterize moiré induced spatial variations in the electronic structure of in-situ grown monolayer V2S3 on Au(111) by means of low temperature scanning tunneling microscopy and spectroscopy. We observe a long-range modulation of the integrated local density of states (LDOS), and quantify this modulation with respect to the moiré superstructure for multiple orientations of the monolayer with respect to the substrate. Scanning tunneling spectroscopy reveals a prominent peak in the LDOS, which is shifted in energy at different points of the moiré superstructure. Comparing ab initio calculations with angle-resolved photoemission, we are able to attribute this peak to bands that exhibit a large out-of-plane d-orbital character. This suggests that the moiré driven variations in the measured density of states is driven by a periodic modulation of the monolayer-substrate hybridization.

These solutions are static and as in the neutral case possess a conical singularity. We show how one may remove the conical singularity by application of a Harrison transformation, which physically corresponds to supporting the charged ring with an electric field. Finally, we discuss the slowly rotating case for arbitrary dilaton coupling.

description: Infectious diseases play a critical role in determining the profitability of individual farms and maintaining the viability of livestock industries, international trade, and trade policies. Thus, it is critical to analyze the economic consequences of infectious diseases, and the effects of producer strategies to control or eliminate diseases in a cost efficient approach. Also, important is the goal to rally support for the development of public disease control programs. This study examined the long-term feasibility and effectiveness of various producer strategies to prevent and control Johne’s disease in dairy herds, an infectious and incurable disease which has significant economic repercussions for the dairy industry. There are few previous studies available on the economic aspects of Johne’s disease and there remains a knowledge gap with regard to the economics of the disease and the economic justification of the disease controls associated with the biological characteristics of the disease. This study contributes to this body of knowledge. We constructed an optimal control model integrating the biology of animals and disease into an economic framework to estimate the best control method in terms of maximizing an individual farm’s profit and minimizing disease elimination periods. Our results show that any Johne’s disease control method yields a higher net present value compared to no control. Implementing a single control strategy can control the disease, but a combination of control strategies in different categories is the most profitable and effective way to reduce the infection rate in a disease-infected herd. The results of the study are directly applicable to managing this disease on US dairy farms and contribute to controlling a high-priority pathogen in an important industry.

They provide a selection of topics at the intersection of particle and astrophysics. The first part gives a short introduction to the theory of electroweak interactions, with specific emphasize on neutrinos. In the second part we apply this framework to selected topics in astrophysics and cosmology, namely neutrino oscillations, neutrino hot dark dark matter, and big bang nucleosynthesis. The last part is devoted to ultra high energy cosmic rays and neutrinos where again particle physics aspects are emphasized. The often complementary role of laboratory experiments is also discussed in several examples.

description: Анализ режима влажности в естественных условиях и при орошении позволяет выделить в зоне аэрации три области. Первая область-активный слой, мощность которого редко превышает 1 метра. Вторая область, ниже активного слоя-область переменной влажности, имеет мощность от 1 до 4 метров. Колебания влажности в ней связаны с сезонными изменениями в поступлении и расходовании влаги в верхнем активном слое. Мощность этой зоны зависит от периода колебания влажности и фильтрационных свойств пород. В верхней части зоны аэрации сезонные изменения интенсивности влагопереноса выше, а с глубиной они уменьшаются. Этим, в частности, объясняется уменьшение амплитуды колебания уровня с увеличением глубины залегания.

description: We investigate the emergence of rigid polycrystalline structures from atomistic particle systems. The atomic interaction is governed by a suitably normalized pair interaction energy, where the `sticky disk' interaction potential models the atoms as hard spheres that interact when they are tangential. The discrete energy is frame invariant and no underlying reference lattice on the atomistic configurations is assumed. By means of $Γ$-convergence, we characterize the asymptotic behavior of configurations with finite surface energy scaling in the infinite particle limit. The effective continuum theory is described in terms of a piecewise constant field delineating the local orientation and micro-translation of the configuration. The limiting energy is local and concentrated on the grain boundaries, i.e., on the boundaries of the zones where the underlying microscopic configuration has constant parameters. The corresponding surface energy density depends on the relative orientation of the two grains, their microscopic translation misfit, and the normal to the interface. We further provide a fine analysis of the surface energies at grain boundaries both for vacuum-solid and solid-solid phase transitions. The latter relies fundamentally on a structure result for grain boundaries showing that due to the extremely brittle setup interpolating boundary layers near cracks are energetically not favorable.

description: This study analyzes the determinants of TE among traditional dairy farms in the State of Wisconsin taking into account dairy farms’ heterogeneity. To do so, we first estimate a production frontier and the level of TE using the SPF framework. Then we analyze the determinants of TI using a quantile regression analysis. The results indicate that the determinants of TE affect in very specific ways farmers with different levels of TE. This result confirms our hypothesis on the importance of controlling for farm heterogeneity when analyzing the determinants of TE. This issue is also important from an empirical point of view. Policy makers could improve the effectiveness of their work by targeting specific agricultural services and aid designed for farmers with different level of TE.

We find constant dilaton solutions by solving both the equations of motion and BPS equations. Our solutions include a free parameter provided by a stack of uncharged space filling branes. We find several AdS_p\times S^q solutions with constant radii for AdS_p and S^q. The curvature of the solutions are of the order of the string scale.

description: We discuss exact quantization of gravitational fluctuations in the half-BPS sector around AdS$_5 \times $S$^5$ background, using the dual super Yang-Mills theory. For this purpose we employ the recently developed techniques for exact bosonization of a finite number $N$ of fermions in terms of $N$ bosonic oscillators. An exact computation of the three-point correlation function of gravitons for finite $N$ shows that they become strongly coupled at sufficiently high energies, with an interaction that grows exponentially in $N$. We show that even at such high energies a description of the bulk physics in terms of weakly interacting particles can be constructed. The single particle states providing such a description are created by our bosonic oscillators or equivalently these are the multi-graviton states corresponding to the so-called Schur polynomials. Both represent single giant graviton states in the bulk. Multi-particle states corresponding to multi-giant gravitons are, however, different, since interactions among our bosons vanish identically, while the Schur polynomials are weakly interacting at high enough energies.

description: Quantum networking allows the transmission of information in ways unavailable in the classical world. Single packets of information can now be split and transmitted in a coherent way over different routes. This aggregation allows information to be transmitted in a fault tolerant way between different parts of the quantum network (or the future internet) - even when that is not achievable with a single path approach. It is a quantum phenomenon not available in conventional telecommunication networks either. We show how the multiplexing of independent quantum channels allows a distributed form of quantum error correction to protect the transmission of quantum information between nodes or users of a quantum network. Combined with spatial-temporal single photon multiplexing we observe a significant drop in network resources required to transmit that quantum signal - even when only two channels are involved. This work goes far beyond the concepts of channel capacities and shows how quantum networking may operate in the future. Further it shows that quantum networks are likely to operate differently from their classical counterparts which is an important distinction as we design larger scale ones.

description: The eradication of child undernutrition and extreme poverty are important objectives for most societies. Countries with higher national incomes usually improve in both dimensions, but not always at the same rate. Using quantile regression, we show that poverty rates tend to decline with increased income at a roughly constant elasticity. In contrast, while the prevalence of child underweight declines at that same elasticity where it is most widespread, the elasticity becomes smaller as underweight becomes less prevalent. This finding suggests a need for increasingly targeted interventions to achieve a given reduction in undernutrition as its prevalence declines.

Here, the presence of dark energy has been established by including a time-dependent $Λ$ term in the Einstein's field equations. This model is compatible with the idea of an accelerating Universe so far as the value of the deceleration parameter is concerned. Possibility of a change in sign of the deceleration parameter is also discussed. The impact of considering the speed of light as variable in the field equations has also been investigated by using a well known time-dependent $Λ$ model.

description: We relate Miura type transformations (MTs) over an evolution system to its zero-curvature representations with values in Lie algebras g. We prove that certain homogeneous spaces of g produce MTs and show how to distinguish these spaces. For a scalar translation-invariant evolution equation this allows to classify all MTs in terms of homogeneous spaces of the Wahlquist-Estabrook algebra of the equation. For other evolution systems this allows to construct some MTs. As an example, we study MTs over the KdV equation, a 5th order equation of Harry-Dym type, and the coupled KdV-mKdV system of Kersten and Krasilshchik.

description: A free boundary problem for the dynamics of a glasslike binary fluid naturally leads to a singular perturbation problem for a strongly degenerate parabolic partial differential equation in 1D. We present a conjecture for an asymptotic formula for the velocity of the free boundary and prove a weak version of the conjecture. The results are based on the analysis of a family of local travelling wave solutions.

description: In this work, we demonstrate that applying deep generative machine learning models for lattice field theory is a promising route for solving problems where Markov Chain Monte Carlo (MCMC) methods are problematic. More specifically, we show that generative models can be used to estimate the absolute value of the free energy, which is in contrast to existing MCMC-based methods which are limited to only estimate free energy differences. We demonstrate the effectiveness of the proposed method for two-dimensional $ϕ^4$ theory and compare it to MCMC-based methods in detailed numerical experiments.

description: An average gate fidelity is a standard performance metric to quantify deviation between an ideal unitary gate transformation and its realistic experimental implementation. The average is taken with respect to states uniformly distributed over the full Hilbert space. We analytically (single-qubit) and numerically (two-qubit) show how this average changes if the uniform distribution condition is relaxed, replaced by parametrized distributions - polar cap and von Mises-Fisher distributions - and how the resulting fidelities can differentiate certain noise models. In particular, we demonstrate that Pauli channels with different noise rates along the three axes can be faithfully distinguished using these augmented fidelities.

description: This paper focuses on recent theoretical developments in political economy and what role they might play in explaining and reforming individual country and global distortions in food and agricultural markets. Four groups of forces are isolated: political governance structures emphasizing the role of democratic mechanisms; the design of polycentric structures for assigned governmental authority for setting policy instruments; market structure and other socioeconomic characteristics; and the role of sector mobility and asset diversification. Each of these forces are distilled and data sources are reviewed that will allow econometric specifications that have both explanatory and policy reform implications.
First Nations women and health care services : the sociopolitical context of encounters with nurses
Creators: name: Browne, Annette Jo
Publisher: name: University of British Columbia
Year: 2009

description: Health care provided to Canadian Aboriginal peoples continues to unfold against a backdrop of colonial relations. This study explored the sociopolitical and historical context of encounters between nurses and First Nations women. Using an ethnographic design and Dorothy Smith's standpoint perspective as the method of inquiry, interactions between nurses and First Nations women were observed in a northern hospital setting. Subsequently, indepth interviews were conducted with First Nations women, nurses, and three other health professionals (N= 35). Incorporating aspects of postcolonial and feminist theories, this study illustrates how dominant ideologies and professional discourses intersect to organize the knowledge and attitudes that nurses bring to their practice. Three related frames of reference were examined: (a) theories of culture, (b) liberal notions of egalitarianism, and (c) popularized images and discourses of Aboriginality. In the absence of competing frames of reference, embedded assumptions about Aboriginal peoples, culture and "difference" influence the relational aspects of nurses' work with First Nations women. Using vignettes from the data, I explain how women's social positioning, material circumstances, past experiences and pragmatism shape their patterns of relating with nurses, their efforts to "get along with all the nurses," and their perceptions of nurses as "all good." Turning their analytical gaze inward, women focused on how they were perceived by health professionals, and how they could best position themselves. To unpack the layers of subtext embedded in women's accounts, critical consideration is given to mediating life circumstances and to particular methodological issues. The study concludes by analyzing strategies for challenging taken-for-granted assumptions and discourses that inadvertently perpetuate colonial relations in health care. The concept of cultural safety, positioned within postcolonial perspectives, is discussed as a means of fostering critical consciousness. By directing nurses to examine historically mediated relations of power, long-standing patterns of paternalism/maternalism, and assumptions about 'race', culture and class relations, cultural safety has the potential to shift nurses' knowledge and attitudes. Locating heath care interactions within these wider historical and sociopolitical contexts can help nurses to more fully contribute to social justice in the realm of Aboriginal health.
A spin pump turnstile: parametric pumping of a spin-polarized current through a nearly-closed quantum dot

description: We investigate parametric pumping of a spin-polarized current through a nearly-closed quantum dot in a perpendicular magnetic field. Pumping is achieved by tuning the tunnel couplings to the left and right lead - thereby operating the quantum dot as a turnstile - and changing either the magnetic field or a gate-voltage. We analyze the quantum dynamics of a pumping cycle and the limiting time scales for operating the quantum dot turnstile as a pure spin pump. The proposed device can be used as a fully controllable double-sided and bipolar spin filter and to inject spins "on demand".

Noisy quantum metrology enhanced by continuous nondemolition measurement

description: We show that continuous quantum nondemolition (QND) measurement of an atomic ensemble is able to improve the precision of frequency estimation even in the presence of independent dephasing acting on each atom. We numerically simulate the dynamics of an ensemble with up to N = 150 atoms initially prepared in a (classical) spin coherent state, and we show that, thanks to the spin squeezing dynamically generated by the measurement, the information obtainable from the continuous photocurrent scales superclassically with respect to the number of atoms N. We provide evidence that such superclassical scaling holds for different values of dephasing and monitoring efficiency. We moreover calculate the extra information obtainable via a final strong measurement on the conditional states generated during the dynamics and show that the corresponding ultimate limit is nearly achieved via a projective measurement of the spin-squeezed collective spin operator. We also briefly discuss the difference between our protocol and standard estimation schemes, where the state preparation time is neglected.

description: Britain – contrary to received wisdom – was not a free trader for most of the 1800s and, despite repeal of the Corn Laws, continued to have higher tariffs than the French until the last quarter of the century War with Louis XIV from 1689 led to the end of all trade between Britain and France for a quarter of a century. The creation of powerful protected interests both at home and abroad (notably in the form of British merchants, and investors in Portuguese wine) led to the imposition of prohibitively high tariffs on French imports -- notably on wine and spirits -- when trade with France resumed in 1714. Protection of domestic interests from import competition allowed the state to raise domestic excises which provided increased government revenues despite almost no increases in the taxes on land and income in Britain. The state ensured compliance not simply through the threat of lower tariffs on foreign substitutes but also through the encouragement of a trend towards monopoly production in brewing and restricted retail sales of beer (which began around 1700 and continued throughout the eighteenth century). This history is analyzed in terms of its effects on British fiscal and commercial policy from the early 1700s to the end of the nineteenth century. The result is a fuller, albeit revisionist account of the rise of the modern state that calls into question a variety of theses in economics and political science that draw on the naive view of a liberal Britain unilaterally moving to free trade in the nineteenth century.
