description: We study possible contributions to the Ds^+ -> omega pi^+ and Ds^+ -> rho^0 pi^+ decay amplitudes. The Ds^+ -> omega pi^+ decay amplitude vanishes when the naive factorization is used, while the Ds^+ -> rho^0 pi^+ decay amplitude arises due to the annihilation contribution. We find that amplitudes for both decays might be a result of the internal K, K^* exchange. The Ds^+ -> omega pi^+ amplitude might obtain additional contribution from Ds^+ -> rho^0 eta (eta') re-scattering. The low experimental bound on the Ds^+ -> rho^0 pi^+ rate can be understood as a result of combination of the pi(1300) pole dominated annihilation contribution and the K,K^* internal exchanges. The calculated branching fractions for Ds^+ -> omega pi^+ and Ds^+ -> rho^0 pi^+ are in agreement with the current experimental results.

description: Globalization is challenging the very core of cooperative governance and ownership decision, especially in Southern European countries, like Portugal, where a large number of producers are organized in traditional and Mediterranean-style agricultural cooperatives. This paper analyses the effects of governance and control variables related with size over two alternative indicators of performance: revenues transferred to members/patrons and capital structure. The results suggest that these cooperatives have difficulties being sustainable in the more competitive global wine markets, if they follow, essentially, a practice of maximum patronage refund, reducing their capacity to improve leverage and to finance more profitable, but risky, long run investments.

description: This paper deals with the potential effects on the profitability of Canary Islands’ farms due to the Special National Insurance System for Agricultural Workers Reform which was put in place in 2009 by the Spanish Government Ministry of Labour and Immigration. The effect on the employers’ National Insurance contributions per working day is analysed. Based on this analysis, the impact on costs and benefits in several farms which cultivate bananas, tomatoes or flowers is evaluated. According to the results, it is concluded that these farms cannot afford the costs’ increase derived from the reform if profitability per product unit or per surface should be maintained. On the other hand, the effect of changes in the contribution basis is softened to a great extent by the application of compensatory deductions, which are likely to disappear on the long term.

description: The United States has used tax credits and mandates to promote ethanol production. To offset the tax credits received by imported ethanol, the United States instituted an import tariff. This study provides insights about the quantitative nature of a U.S. trade policy that would establish a free-market price for ethanol, given the U.S. ethanol mandate and tax credit. The theoretical results from a horizontally related ethanol-gasoline partial equilibrium model show that the United States should provide an import subsidy rather than impose a tariff. The empirical results quantify that this import subsidy is 9 cents, instead of a 57 cent import tariff, per gallon of ethanol.

description: As dairy farms grow and specialize in milking cows, raising replacement heifers is increasingly outsourced. Perhaps the largest challenge of outsourcing the heifer enterprise involves quality, measured as milk production potential, and the possibility for moral hazard due to hidden action on the part of the custom heifer grower. A principal-agent framework was used to elicit contract terms to provide incentives for the heifer grower to achieve desired growth rates, and enable the return of the heifer to the dairy farm on an accelerated time frame, without sacrificing quality. To mitigate incentive asymmetries, bonuses and deductions are proposed.
Evaluation methodology for mechatronic systems

Publisher: name: University of British Columbia
Year: 2009

description: With the ever increasing demand for engineering products and systems having added functionalities, compactness and energy efficiency, more and more mechanical products and systems are being integrated with electronics and sophisticated computer control giving rise to a whole new breed of products and systems termed 'mechatronic systems.' These systems are complex and "mixed" in nature due to the integration of components of different types and belonging to different engineering disciplines, thus requiring new approaches in design and evaluation of such systems. Furthermore, the evaluation of existing systems which have been modified using advanced computer control and integration of electronics, is necessary in order to assess their effectiveness. This thesis addresses the issue of evaluation of a mechatronic system, particularly one which has been modified by adding electronic/computer control systems. The existing components in the system should be able to cope with the new requirements imposed by the control system. A novel evaluation method is developed to determine the degree of integration of the components in a mixed system, based on energy flow, giving particular attention to the power domain of the system. To test the usefulness of the methodology, the developed methodology is applied to a practical mechatronic system, the electro-hydraulic manipulator system of an industrial fish cutting machine which has been developed in the Automation Industrial Laboratory of the University of British Columbia. Computer simulations are carried out as well on the system to investigate effectiveness of the method, since it is largely dependent on a valid model of the evaluated system.

description: Researchers use Nielsen Homescan data, which provide detailed food-purchase information from a panel of U.S. households, to address a variety of important research topics. However, some question the credibility of the data since the data are self-recorded and the recording process is time-consuming. Matching purchase records from 2004 Homescan data with data obtained from a large grocery retailer, it is evident that quantities purchased are reported more accurately in Homescan than are prices. Many of the price differences may be driven by the way Nielsen imputes prices: when available, Nielsen uses store-level prices instead of the actual price paid by the household. There are also differences by household type in the tendency to make mistakes that are correlated with demographic variables. However, the fraction of variance explained by the documented recording errors is in line with other research data sets for which cross-validation studies have been conducted.

description: Giving consideration to the bills and laws being discussed in Congress during the last few years regarding immigration reform, the need has arisen to study the effects of immigrant labor on the dairy industry. The objective of this study is to consider the economic impacts of reducing the availability of immigrant workers in the United States. This analysis utilizes the IMPLAN model, developed and maintained by the Minnesota IMPLAN Group, for analyzing the effects of 20 percent, 50 percent and 100 percent reductions in immigrant labor within the dairy industry. IMPLAN maps the economy using an input/output structure that “describes commodity flows from producers to intermediate and final consumers”. The employment and production data used as inputs into the model were gathered using a national survey of 5,005 dairy farms with respondents from 47 states and a response rate of 41.4 percent. Approximately 50 percent of the 5,005 dairy farms surveyed use immigrant labor. Results of the analysis estimate baseline nationwide economic activity, employment, and total value added impacts attributable to dairy farming to be $48.1 billion, 301,300 jobs, and $19.6 billion, respectively. With a 20 percent reduction in immigrant labor, the values fall to $43.6 billion, 274,800 jobs, and $17.8 billion. Under a 50 percent reduction in immigrant labor the values are $36.9 billion, 235,000 jobs, and $15.1 billion. Under a 100 percent reduction in immigrant labor scenario, the values fall to an estimated $25.7 billion, 168,700 jobs, and $10.5 billion. These reported figures include the impacts directly linked to the dairy industry as well as those to the rest of the economy. This analysis reports both intra- and inter-industry impacts but gives special attention to the inter-industry impacts within the economy.

description: Local and organic food systems represent some of the many food sector innovations of the past decade that signal that consumers are increasingly diverse and have heterogeneous preferences that reflect their unique values and preferences (Thilmany, Bond and Bond, 2008). Yet, regardless of the significant attention and growth surrounding sustainable foods, there is still a demand for research investigating the intersection of economic and psychological factors that can aid in predicting and explaining consumer behavior. This paper uses an attitude-behavior framework, the Theory of Planned Behavior, to explore the predictive ability of psychological concepts of willingness to pay for different attributes associated with sustainable foods. Consumer attitudes toward organic, fair trade and local labeled food as well as their level of "effectiveness" are measured in an effort to understand behavioral intentions. This study uses approximately 1000 responses from a 2008 nationwide survey of consumers to investigate the role of public benefits assigned to sustainable food products manifesting in a potential increase in willingness to pay.

A global model of particle acceleration at pulsar wind termination shocks

description: Pulsar wind nebulae are efficient particle accelerators, and yet the processes at work remain elusive. Self-generated, microturbulence is too weak in relativistic magnetized shocks to accelerate particles over a wide energy range, suggesting that the global dynamics of the nebula may be involved in the acceleration process instead. In this work, we study the role played by the large-scale anisotropy of the transverse magnetic field profile on the shock dynamics. We performed large two-dimensional particle-in-cell simulations for a wide range of upstream plasma magnetizations. A large-scale velocity shear and current sheets form in the equatorial regions and at the poles, where they drive strong plasma turbulence via Kelvin-Helmholtz vortices and kinks. The mixing of current sheets in the downstream flow leads to efficient nonthermal particle acceleration. The power-law spectrum hardens with increasing magnetization, akin to those found in relativistic reconnection and kinetic turbulence studies. The high end of the spectrum is composed of particles surfing on the wake produced by elongated spearhead-shaped cavities forming at the shock front and piercing through the upstream flow. These particles are efficiently accelerated via the shear-flow acceleration mechanism near the Bohm limit. Magnetized relativistic shocks are very efficient particle accelerators. Capturing the global dynamics of the downstream flow is crucial to understanding them, and therefore local plane parallel studies may not be appropriate for pulsar wind nebulae and possibly other astrophysical relativistic magnetized shocks. A natural outcome of such shocks is a variable and Doppler-boosted synchrotron emission at the high end of the spectrum originating from the shock-front cavities, reminiscent of the mysterious Crab Nebula gamma-ray flares.

description: Since the discovery of the pseudogap and Fermi arc states in underdoped cuprates, the understanding of such non-Fermi-liquid states and the associated violation of Luttinger's theorem have been the central theme in correlated electron systems. However, still lacking is a well-accepted theoretical framework to unambiguously explain these metallic states that are clearly beyond Landau's Fermi liquid and Luttinger's theorem of a Fermi surface and electron filling. Here, we design a lattice model of orthogonal metals with fermion and Ising matter fields coupled to topological order and, by solving the model via unbiased quantum Monte Carlo simulation at generic electron fillings, find that the system gives birth to phenomena of the Fermi arc and pseudogap in the single-particle spectrum that go beyond the Luttinger sum rule with broken Fermi surface but no symmetry breaking. The pseudogap and Fermi arcs coexist with a background of a deconfined Z2 gauge field, and we further find that the confinement transition of the gauge field triggers a superconductivity instability and that the hopping of the gauge-neutral fermions brings the "large" Fermi surface back from the Fermi arc state. Our unbiased numerical results provide a concrete model realization and theoretical framework for the coupling between gauge field and fermions and, in the process, generate the rich phenomena of the pseudogap, the Fermi arc, and superconductivity in generic correlated electron systems.

Costs associated with urban congestion will test the capacity of the region's food system to deliver a continuous flow of safe, reasonably priced, fresh and processed foods. Pressure to better connect urban areas to rural hinterlands and for trade liberalization will intensify to meet food needs of these growing urban areas. Differential rates of population growth and population aging among economies will affect the quantity and composition of foods demanded, hence private sector strategies and public policies.
AUV hydrodynamics and modelling for improved control
Creators: name: Ostafichuk, Peter Michael
Publisher: name: University of British Columbia
Year: 2009

description: The performance and management of control surfaces on a near-surface autonomous underwater vehicle (AUV) were examined in terms of hydrodynamics, modelling, and control. Experiments were conducted using a one-quarter scale physical model of the International Submarine Engineering (ISE) Mark II DOLPHIN AUV. The experiments involved extensive tests in wind tunnels and a tow tank and included both force measurement and flow visualization studies. The experiment results were used to mathematically describe the performance of AUV control surfaces for use in simulation. Additionally, based on the new control surface hydrodynamics information, enhancements were made to the vehicle controller. For the various vehicle and controller configurations, the overall vehicle performance was evaluated through simulation using representative manoeuvres and operating conditions. In straight and level flight, the performance of the forward control surfaces (bowplanes) was well described through existing semi-empirical predictions. Trailing vortices shed by the forward control surfaces significantly affected the performance of the aft control surfaces (sternplanes). This interaction was a strong function of vehicle orientation and was accurately predicted by a simple potential flow model. Significant changes were noted to bowplane performance when the vehicle was oriented with trim or yaw. The influence of waves on the planes, including the dependence on vehicle speed and depth, agreed well with analytical predictions. In simulation, the effect on vehicle performance of changes in the control surface modelling, control surface configuration, and the controller design were studied. Although significantly different mathematical models of control surface performance were developed, they were found to have similar effects on the overall vehicle performance. Changes to the control surface configuration had a very significant effect on performance. In particular, increasing the bowplane span and adding dihedral to the bowplanes or sternplanes were both found to improve manoeuvring and minimize the effect of waves on the vehicle. Only minor differences in performance were noted between different PD controller implementations. The PD controllers were sensitive to modeling errors and exhibited unstable behavior in one instance. A linear quadratic gaussian controller with loop transfer recovery (LQG/LTR) was more robust and was further improved with the incorporation of sliding mode control.

description: In this paper the conceptual framework of individual farmers' adoption decisions of new agricultural technologies is used to identify factors that influence adoption modified fanya juu terraces in semi-arid eastern Kenya. The adoption decision model was specified using farm and farmers' characteristics and technology characteristics though likely to influence farmers' adoption behaviour. To test intensity of adoption a Torbit model was specified and estimated. Results of logit regression analysis reveal that access to markets, education, costs, technology attributes, labour, credit and risk preferences significantly influenced adoption decisions. Results from the estimated intensity of adoption model (tobit) show that variation in the proportion of land with technology was significantly influenced by age and level of education of the household head, access to markets, technology attributes, credit, off-farm income and risks.
$ΛCDM$ periodic cosmology

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

description: We examine the possibility that Universe expansion be made of some $ΛCDM$ expansions repeating periodically, separated by some inflation and radiation dominated phases. This so-called $ΛCDM$ periodic cosmology is motivated by the possibility that inflation and the present phase of accelerated expansion be due to the same dark energy. Then, in a phase space showing the variation of matter density parameter $Ω_m$ with respect to this of the radiation $Ω_r$, the curve $Ω_m(Ω_r)$ looks like a closed trajectory that Universe could run through forever. In this case, the end of the expansion acceleration of the $ΛCDM$ phase is the beginning of a new inflation phase. We show that such a scenario implies the coupling of matter and/or radiation to dark energy. We consider the simplest of these $ΛCDM$ periodic models i.e. a vacuum energy coupled to radiation. From matter domination phase to today, it behaves like a $ΛCDM$ model, then followed by an inflation phase. But a sudden and fast decay of the dark energy into radiation periodically ends the expansion acceleration. This leads to a radiation dominated Universe preceding a new $ΛCDM$ type expansion. The model is constrained with Markov Chain Monte Carlo simulations using supernovae, Hubble expansion, BAO and CMB data and fits the data as well as the $ΛCDM$ one.

description: Within the framework of the AdS/CMT correspondence asymptotically anti-de Sitter black holes in four space-time dimensions can be used to analyse transport properties in two space dimensions. A non-linear renormalisation group equation for the conductivity in two dimensions is derived in this model and, as an example of its application, both the Ohmic and Hall DC and AC conductivities are studied in the presence of a magnetic field, using a bulk dyonic solution of the Einstein-Maxwell equations in asymptotically AdS$_4$ space-time. The ${\cal Q}$-factor of the cyclotron resonance is shown to decrease as the temperature is increased and increase as the charge density is increased in a fixed magnetic field. Likewise the dissipative Ohmic conductivity at resonance increases as the temperature is decreased and as the charge density is increased. The analysis also involves a discussion of the piezoelectric effect in the context of the AdS/CMT framework.

description: The existence in the physical QCD vacuum of nonzero gluon condensates, such as $$, requires dominance of gluon fields with finite mean action density. This naturally allows any real number value for the unit ``topological charge'' $q$ characterising the fields approximating the gluon configurations which should dominate the QCD partition function. If $q$ is an irrational number then the critical values of the $θ$ parameter for which CP is spontaneously broken are dense in $\mathbb{R}$, which provides for a mechanism of resolving the strong CP problem simultaneously with a correct implementation of $U_{\rm A}(1)$ symmetry. We present an explicit realisation of this mechanism within a QCD motivated domain model. Some model independent arguments are given that suggest the relevance of this mechanism also to genuine QCD.

Research on Survivability Strategies of Virtual Network

description: Virtualization facilitates heterogeneous cloud applications to share the same physical infrastructure with admirable flexibility, while resource efficiency and survivability are critical concerns for virtual network embedding (VNE). As more and more internet applications migrate to the cloud, the resource efficiency and the survivability of VNs, such as single link failure or large-scale disaster survivability, have become crucial issues. Separating the VNE problem into node and link mapping sub-problems without coordination might cause a high embedding cost. This dissertation presents two independent approaches to solve the aforementioned challenges. First, we study two-stage coordinated survivable VNE (SVNE) problem and propose an adaptive path splitting based SVNE (APSS) scheme. We first develop a concise anchor node strategy to restrict the solution space of the candidate substrate nodes, which coordinates node mapping with link mapping to limit the distance spans of the virtual links. Then, we employ an adaptive path splitting policy to provide full protection against single-link failures with partial backup resource, and design an agile frequency slot windows choosing mechanism to mitigate the spectrum fragmentation for link resource efficiency. Simulation results demonstrate that the proposed APSS scheme can achieve satisfactory performance in terms of spectrum utilization and blocking ratio. Second, we propose a synchronous evacuation strategy for VNs with dual virtual machines (VMs) inside a disaster risk zone (DRZ), which suffer higher risks than the VNs with single. The evacuation strategy exploits post-copy technique to sustain the online service alive and enhances synchronous VM migrations to shorten the dual-VM evacuation time. Numerical results show that the proposed strategy can outperform the best-effort scheme in terms of average and total evacuation times of dual-VMs.

description: Choice modelling is increasingly being used to generate estimates of the value of changes in environmental quality. This is partly because of the informational efficiencies of the technique, but also because of concern about the accuracy of contingent valuation. Experimental evidence has, however, demonstrated that choice modelling tends to produce much higher valuation estimates than contingent valuation. One possible explanation for the divergence between choice modelling and contingent valuation estimates is the lack of incentive compatibility with the former technique. This potentially has several sources, including having no provision rule (eg a referendum), respondents choosing between more than two alternatives, and repeated choices. We report on the results of a series of experiments involving over 2000 subjects designed to test whether a lack of incentive compatibility is responsible for divergences in value estimates.
Dilute monopole gas, magnetic screening and k-tensions in hot gluodynamics

description: An adjoint multiplet of screened monopoles forming a dilute gas fits very well lattice data at high $T$. There are now seven ratios for k-strings available, checking within a few percent with the prediction $k(N-k)$. The diluteness turns out to be a small parameter for SU(N) gluodynamics, to a good approximation ($1\over N^2$) independent of the value of $N$, and also independent of $T$. This suggests a dilute Bose-Einstein gas, with a BE transition at the deconfinement temperature $T_c$.

description: This study focuses on public investments and policy reforms for leveraging growth spillovers at the African regional level. A conceptual framework that is built on the endogenous growth theory and the new economic geography is presented first to gain a better understanding of the underlying theory and empirical evidence on regional integration and growth spillovers. In order to demonstrate the potential benefits from greater cross-border technology spillovers in Africa, as well as from trade liberalization and investment in infrastructure, results from ex-ante simulations using partial and general equilibrium models are then presented and discussed. Results indicate that sizeable regional spillover benefits can be obtained by permitting greater crossborder transfer and adoption of improved technologies, sometimes as large as three to four times the gain in direct benefits obtained within the innovating countries. This is especially true for commodities like mutton, groundnuts and sorghum. Moreover, reducing trade barriers between African countries in agriculture and non-agriculture can significantly increase intra-regional agricultural trade and raise economic growth rates. The simulations also demonstrate that improving transportation infrastructure generates the most encouraging results, increasing agricultural income by as much as 10%. The findings in this study confirm that greater regional cooperation in agricultural research and development, harmonization of regulatory standards for technology adaptation, and harmonization and liberalization of trade systems within the region could play a crucial role in expanding opportunities for African farmers. Therefore, strengthening linkages among African countries through infrastructure, agricultural R&D, and expansion of intraregional trade can generate large spillovers and leverage regional growth.

description: Most counterparts of the identified low-latitude gamma-ray sources are Isolated Neutron Stars (INSs). They are characterized by an extremely high value of the X/optical flux ratio, therefore a systematic X-ray/optical coverage of the fields of unidentified low-latitude gamma-ray sources is the best way to unveil possible INS counterparts. Since the low-latitude sources are heavily affected by the interstellar absorption in both the X-ray and optical bands, we decided to apply the above strategy to two middle-latitude EGRET sources, which could belong to a local galactic population: 3EG J0616-3310 and 3EG J1249-8330. Here we report on the global X-ray characterisation of about 300 objects, on their candidate optical counterparts and on the preliminary results of their identification.

description: We report on the precise localization of the low mass X-ray binaries X1624-490 and X1702-429 with the Chandra HRC-I. We determine the best positions to be 16:28:02.825 -49:11:54.61 (J2000) and 17:06:15.314 -43:02:08.69 (J2000) for X1624-490 and X1702-429, respectively, with the nominal Chandra positional uncertainty of 0.6". We also obtained deep IR observations of the fields of these sources in an effort to identify the IR counterparts. A single, faint (Ks=18.3 +/- 0.1) source is visible inside the Chandra error circle of X1624-490, and we propose this source as its IR counterpart. For X1702-429, a Ks=16.5 +/- 0.07 source is visible at the edge of the Chandra error circle. The brightness of both counterpart candidates is comparable to that of other low mass X-ray binary IR counterparts when corrected for extinction and distance.

description: We investigate the non-Abelian Bianchi identities in pure SU(2) lattice Yang-Mills theory in three and four dimensions. The non-Abelian Stokes theorem proposed recently allows to formulate the Bianchi identities in terms of local physical fluxes. Then the violation of Bianchi identities becomes a well defined concept ultimately related to chromomagnetic fields degeneracy points. We present numerical evidences that in D=4 the suppression of the Bianchi identities violation destroys confinement while the removal of the degeneracy points drives the theory to the topologically non-trivial sector.
