description: The need to provide agricultural information to farmers has led to emergence of numerous ICT-based MIS projects in developing country. These projects aim at promoting commercialization of smallholder agriculture and subsequently their welfare. This study examines the welfare effects of one such project in western Kenya. It uses household food security and access to medical health services as proxies of welfare. The study finds that farmers that use ICT-based market information are more food secure and have better access to medical health services than their counterpart. It highlights policy implications of these findings.

Bush, ridge, rove & the creation of the Department of Homeland Security
Creators: name: Gillies, James Clark
Publisher: name: University of British Columbia
Year: 2009

description: In June 2002, President George W. Bush asked Congress to create a Department of Homeland Security to better protect the United States against further terrorist attacks. The public service reorganization that has taken place is perhaps the largest in American history apart from the post-World War II armed forces restructuring. But it remains to be seen whether this initiative will be effective. This thesis is an analysis of the factors at play in the creation of the Department of Homeland Security. It focuses on how the department came about, and what challenges, both political and bureaucratic, those who administer and manage the department will face. The thesis relies upon existing public management and bureaucratic theory literature to assess the new department. It also analyzes the Bush administration's governing style and their execution of presidential power. In particular, it discusses the role played by Bush's chief strategist Karl Rove in forging the new department. The Department of Homeland Security is not only a timely topic and one that allows for investigation of the federal U.S. public service but it is also about reinventing government, not through small endeavours internal to a department, but through the creation of a new and large organization.
Quasicharacters, recoupling calculus and costratifications of lattice quantum gauge theory

description: We study the algebra of invariant representative functions over the N-fold Cartesian product of copies of a compact Lie group G modulo the action of conjugation by the diagonal subgroup. We construct a basis of invariant representative functions referred to as quasicharacters. The form of the quasicharacters depends on the choice of a reduction scheme. We determine the multiplication law of quasicharacters and express their structure constants in terms of recoupling coefficients. Via this link, the choice of the reduction scheme acquires an interpretation in terms of binary trees. We show explicitly that the structure constants decompose into products over primitive elements of 9j symbol type. For SU(2), everything boils down to the combinatorics of angular momentum theory. In the final part, we show that the above calculus enables us to calculate the matrix elements of bi-invariant operators occuring in quantum lattice gauge theory. In particular, both the quantum Hamiltonian and the orbit type relations may be dealt with in this way, thus, reducing both the construction of the costratification and the study of the spectral problem to numerical problems in linear algebra. We spell out the spectral problem for G=SU(2) and we present sample calculations of matrix elements of orbit type relations for the gauge groups SU(2) and SU(3). The methods developed may be useful in the study of virtually all quantum models with polynomial constraints related to some symmetry.

description: Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method. Comparing estimates across all three common approaches for estimating the economic cost of exposure to an air pollutant is an important contribution to the literature. This study uses data from the largest wildfire in Los Angeles County’s modern history, the Station Fire of 2009. Our results show that a simple cost of illness estimate is about $3 per day of symptoms, the averting behavior method results in a WTP value of $43 or $94 to avoid one day of wildfire-smoke induced symptom days, depending on the model used, and the contingent valuation method results in a WTP estimate of $74 - $98 to avoid one day of wildfire-smoke induced symptom days, depending on model specification.

description: We report a broadband terahertz time-domain spectroscopy (THz-TDS) which enables twenty vibrational modes of adenosine nucleoside to be resolved in a wide frequency range of 1-20 THz. The observed spectroscopic features of adenosine are in good agreement with the published spectra obtained using Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy. This much-extended bandwidth leads to enhanced material characterization capability as it provides spectroscopic information on both intra-molecular and inter-molecular vibrations. In addition, we also report a low-cost Frequency Modulation Continuous Wave (FMCW) imaging system which has a fast measurement speed of 40,000 waveforms per second. Cross-sectional imaging capability through cardboard has also been demonstrated using its excellent penetration capability at a frequency range of 76-81 GHz. We anticipate that the integration of these two complementary imaging technologies would be highly desirable for many real-world applications because it provides both spectroscopic discrimination and penetration capabilities in a single instrument.

description: El Nino is an extreme weather event featuring unusual warming of surface waters in the eastern equatorial Pacific Ocean. This phenomenon is characterized by heavy rains and floods that negatively affect the economic activities of the impacted areas. Understanding how this phenomenon influences consumption behavior at different granularity levels is essential for recommending strategies to normalize the situation. With this aim, we performed a multi-scale analysis of data associated with bank transactions involving credit and debit cards. Our findings can be summarized into two main results: Coarse-grained analysis reveals the presence of the El Niño phenomenon and the recovery time in a given territory, while fine-grained analysis demonstrates a change in individuals' purchasing patterns and in merchant relevance as a consequence of the climatic event. The results also indicate that society successfully withstood the natural disaster owing to the economic structure built over time. In this study, we present a new method that may be useful for better characterizing future extreme events.

description: Hidden theories coupled to the SM may provide emergent (dark) vectors, that are composites/bound-states of the hidden fields. This is motivated by paradigms emerging from the AdS/CFT correspondence but it is a more general phenomenon. We explore the general setup and find that UV interactions among currents or charged fields give rise to emergent vectors in the IR. We study the general properties of such vectors and argue that they can be generically different from fundamental dark photons that have been studied so far.

description: Economic research generates a wide array of benefits. These include information, technological change, and improved policy. There are few quantitative studies of the benefits of economic research, and some benefits may be misattributed to biological and physical research. To be productive, economic research must be transmitted and the user must be able to use it. Therefore, investment in extension outreach and economic literacy are important to improve its impact. Even casual observation suggests that economic research is valuable, but noneconomists must be convinced of this. Since benefits are likely to be concentrated in a small number of successful projects, a useful approach to the assessment of the benefits of research is to identify these projects and their results. The analysis must recognize that the accuracy of any estimates of benefits is uncertain. In addition, the argument behind the estimates should be transparent, relying on documentation and testimony from users, policymakers, and noneconomists. Assessments of the benefits of economic research provide information that can be used both to justify support for economic research and to allocate monies among lines of research.
Tropospheric ozone in the Lower Fraser Valley, British Columbia and the threat of injury to forest plants
Creators: name: Krzyzanowski, Judi
Publisher: name: University of British Columbia
Year: 2009

description: During the summers of 2001 and 2002 ambient ozone levels were measured as hourly averages in parts per billion (ppb) at four sites of differing elevation (200, 400, 600 and 1200 m) in the Lower Fraser Valley (LFV), British Columbia. A l l sites were located in forest clearings and experienced hourly averages as low as Oppb, and >70ppb. Mean seasonal concentrations show an increase in ambient ozone with elevation due to consistently high nocturnal concentrations and lack of diurnal variation at higher altitudes. Diurnal patterns are in agreement with previous studies showing a peak in concentration in the late afternoon, and a morning increase due to photochemical production and residual layer down mixing. The occurrence of an upper level ridge coinciding with a thermal trough along the coast, cause above average ozone levels to occur, and may cause the National Ambient Air Quality Objective of 82ppb to be exceeded. Cumulative ozone exposures were measured with height in a forest canopy using OGAWA passive samplers mounted to a 10.5m tower. A strong power-law increase in ozone with height was found due to a number of potential processes including deposition and chemical destruction at the surface, uptake by vegetation, and dynamic stability inhibiting down mixing. This relationship shows plants in the LFV may be acting as an effective ozone sink. Plants uptake ozone direcdy through leaf stomates where the pollutant may directly injure foliage. A preliminary survey of native shrubs exhibiting visible ozone injury symptoms suggests that current concentrations of tropospheric ozone in the LFV may be high enough to cause injury to forest species, however more research is required in order to determine the threat of ozone to these economically and culturally important forests.

description: This paper suggests practical methods for assessing policy research programs, both ex post and ex ante. Measuring the benefits of policy research is difficult: the path of causation between research and policy change is nearly always uncertain; multiple factors influence any particular policy change; policies are diverse in nature as are their intended and actual effects; and some effects of policy research are not priced in the market. Many of the benefits of changes in policy stem from the reduced cost of welfare-improving institutional change. Economic surplus analysis can be used to assess such changes. In some cases, Bayesian decision theory may be helpful in evaluating policy research, although it is usually difficult to obtain estimates of the probability distributions a decision-maker has before the research becomes available. Subjective estimates of parameters and some measure of their degree of uncertainty, are likely to be needed for an economic surplus model. The paper suggests a set of steps for policy research evaluation. It is applied to two cases: an evaluation of pesticide policy research in Brazil, and an evaluation of policies affecting deforestation in Indonesia.
X-ray Evidence for Multiple Absorbing Structures in Seyfert Galaxies

description: We have used X-ray spectra to measure attenuating columns in a large sample of Seyfert galaxies. Over 30 of these sources have resolved radio jets, allowing the relative orientation of the nucleus and host galaxy to be constrained. We have discovered that the distribution of absorbing columns is strongly correlated with the relative orientation of the Seyfert structures. This result is inconsistent with unification models including only a torus and is instead most readily explained if a second absorber is included: in addition to a Compton-thick, parsec-scale torus there would also be a larger-scale absorber with N_H < 10^{23} cm^{-2}. The second absorber is aligned with the host galactic plane while the torus is arbitrarily misaligned.

description: What are the “returns” to policy-oriented research in the social sciences? One presumes that the positive net benefits to society, or at least a certain segment of society, would be treated as returns, but how does one determine what these benefits are? Clearly benefits to some social science research are available because society continued to fund it, albeit at different levels in different locations and times. This paper cannot fully answer the questions of what it is we seek to measure in any empirical sense, although it will discuss this issue. The returns in the marketplace for social science research are those that exist in the eye of the customer who bears the cost of the research. This paper's primary goal is to offer the client some ways of measuring these returns. It does this with particular emphasis on methods that are often overlooked, even though some of them have been available to the analyst for decades. It also explains some of the costs and benefits of each method and explains how some of them may be used together in order to achieve a higher level of efficacy in measurement.

description: Any evaluation of the benefits of policy-oriented social science research faces fundamental difficulties. These include the uncertainty in determining a causal link between research and the outcome of a policy or the value of a policy outcome. Nonetheless, firm connections can be established between policy research and policy outcomes if there are strong links that bridge the gaps between social science research and the various parts of the policy process. These connections can be established often enough to make it possible to learn about the relationship between research and outcome and the key variables that affect the social profitability of the underlying research. This essay uses the author's experience with agricultural price policies in Asia, Indonesia in particular, to examine these connections. Four issues pervade the analysis of price policy in Asia: How does an analyst know what policy is best? How can an analyst best communicate the results of research to policymakers? Can a new policy be implemented? Does the new policy work? This last issue, the evaluation of policy, is often neglected, but it can provide an important input into the design of policy and should be made an integral part of any policy process. The author's experience in Indonesia suggests four factors that can make policy-oriented research successful. First, the analyst should be involved with the same policymakers or in the same policy setting for the long term. Second, there is a need to find a balance between keeping analysis and advice confidential and the ultimate publication of the key models and results. Third, the analysts should rely on the analytical paradigms of the mainstream of the economic profession even while examining deviations from their underlying assumptions. Lastly, there should be continuing demand from policymakers for problem-oriented analysis.
A proposal for measuring the benefits of policy-oriented social science research

Subjects: Research and Development/Tech Change/Emerging Technologies

description: This paper addresses the problem of how to measure the benefits of policy-oriented social science research. It argues that social science research promotes economic efficiency in three different ways—it fosters efficiency in the public sector both directly and through effects on the general public, and it increases the efficiency of the private sector. The paper also proposes a practical empirical methodology for measuring the benefits of policy-oriented social science research. The proposed methodology includes a three-stage analysis of a cross-section of countries. The relationship between research and policy is estimated first. Then an estimate is made of the relationship between policy and economic growth. Finally, these estimates are used to deduce the relationship between research and economic growth.

description: A method to efficiently compute, in a automatic way, helicity amplitudes for arbitrary scattering processes at leading order in the Standard Model is presented. The scattering amplitude is evaluated recursively through a set of Dyson-Schwinger equations. The computational cost of this algorithm grows asymptotically as 3^n, where n is the number of particles involved in the process, compared to n! in the traditional Feynman graphs approach. Unitary gauge is used and mass effects are available as well. Additionally, the color and helicity structures are appropriately transformed so the usual summation is replaced by Monte Carlo techniques. Some results related to the production of vector bosons and the Higgs boson in association with jets are also presented.

description: In the early 80's, R. Rüdiger published a pair of articles in which it was found the most general conserved charges associated to the motion of particles with spin moving in curved spacetime. In particular, it was shown that besides the well-known conserved quantity associated to Killing vectors, it is also possible to have another conserved quantity that is linear in the spin of the particle if the spacetime admits a Killing-Yano tensor. However, in these papers it was proved that in order for this new scalar to be conserved two obscure conditions involving the Killing-Yano tensor and the curvature must be obeyed. In the present paper we try to shed light over these conditions and end up proving that this conserved quantity is useless for most physically relevant spacetimes. Notably, for particles moving in vacuum (Einstein spacetimes) this conserved scalar constructed with the Killing-Yano tensor will not help on the integration of the equations of motion. Moreover, we prove that, as a consequence of these obscure conditions, the Killing-Yano tensor must be covariantly constant.

Two Superconducting Phases in the d=3 Hubbard Model: Phase Diagram and Specific Heat from Renormalization-Group Calculations

description: The phase diagram of the d=3 Hubbard model is calculated as a function of temperature and electron density n_i, in the full range of densities between 0 and 2 electrons per site, using renormalization-group theory. An antiferromagnetic phase occurs at lower temperatures, at and near the half-filling density of = 1. The antiferromagnetic phase is unstable to hole or electron doping of at most 15%, yielding to two distinct "tau" phases: for large coupling U/t, one such phase occurs between 30-35% hole or electron doping, and for small to intermediate coupling U/t another such phase occurs between 10-18% doping. Both tau phases are distinguished by non-zero hole or electron hopping expectation values at all length scales. Under further doping, the tau phases yield to hole- or electron-rich disordered phases. We have calculated the specific heat over the entire phase diagram. The low-temperature specific heat of the weak-coupling tau phase shows a BCS-type exponential decay, indicating a gap in the excitation spectrum, and a cusp singularity at the phase boundary. The strong-coupling tau phase, on the other hand, has characteristics of BEC-type superconductivity, including a critical exponent alpha approximately equal to -1, and an additional peak in the specific heat above the transition temperature indicating pair formation. In the limit of large Coulomb repulsion, the phase diagram of the tJ model is recovered.

description: Automatic supervised classification with complex modelling such as deep neural networks requires the availability of representative training data sets. While there exists a plethora of data sets that can be used for this purpose, they are usually very heterogeneous and not interoperable. In this context, the present work has a twofold objective: i) to describe procedures of open-source training data management, integration, and data retrieval, and ii) to demonstrate the practical use of varying source training data for remote sensing image classification. For the former, we propose SatImNet, a collection of open training data, structured and harmonized according to specific rules. For the latter, two modelling approaches based on convolutional neural networks have been designed and configured to deal with satellite image classification and segmentation.

Based on novel empirical evidence as well as secondary sources, this paper shows that emerging countries with diverse institutional models and innovation strategies, have been driving the process of technological modernization and product standardization. Newcomers in the wine sector have responded particularly effectively to changes in consumption habits, and in aligning emerging scientific approaches with institutional building efforts and successful marketing strategies.
Reconstruction and identification of boosted di-$τ$ systems in a search for Higgs boson pairs using 13 TeV proton$-$proton collision data in ATLAS

description: In this paper, a new technique for reconstructing and identifying hadronically decaying $τ^+τ^-$ pairs with a large Lorentz boost, referred to as the di-$τ$ tagger, is developed and used for the first time in the ATLAS experiment at the Large Hadron Collider. A benchmark di-$τ$ tagging selection is employed in the search for resonant Higgs boson pair production, where one Higgs boson decays into a boosted $b\bar{b}$ pair and the other into a boosted $τ^+τ^-$ pair, with two hadronically decaying $τ$-leptons in the final state. Using 139 fb$^{-1}$ of proton$-$proton collision data recorded at a centre-of-mass energy of 13 TeV, the efficiency of the di-$τ$ tagger is determined and the background with quark- or gluon-initiated jets misidentified as di-$τ$ objects is estimated. The search for a heavy, narrow, scalar resonance produced via gluon$-$gluon fusion and decaying into two Higgs bosons is carried out in the mass range 1$-$3 TeV using the same dataset. No deviations from the Standard Model predictions are observed, and 95% confidence-level exclusion limits are set on this model.

description: In the framework of the thermodynamic perturbation theory for fluids we study how the phase diagram of an isotropic repulsive soft-core attractive potential, where a liquid-liquid phase transition exists in addition to the standard gas-liquid phase transition, changes by varying the parameters of the potential. We show that existence of the liquid-liquid transition is determined by the interplay of the parameters of the potential and the structure of a reference liquid.

description: We have investigated the magnetic correlations in the candidate Weyl semimetals EuCd$_2Pn_2$, ($Pn$=As, Sb) by resonant elastic X-ray scattering (REXS) at the Eu$^{2+}$ $M_5$ edge. The temperature and field dependence of the diffuse scattering of EuCd$_2$As$_2$ provide direct evidence that the Eu moments exhibit slow ferromagnetic correlations well above the Néel temperature. By contrast, the diffuse scattering in the paramagnetic phase of isostructural EuCd$_2$Sb$_2$ is at least an order of magnitude weaker. The FM correlations present in the paramagnetic phase of EuCd$_2$As$_2$ could create short-lived Weyl nodes.

description: The SUSY signals in the dominant stau-neutralino coannihilation region at a 500(800) GeV linear collider are investigated. The region is consistent with the WMAP measurement of the cold dark matter relic density as well as all other current experimental bounds within the mSUGRA framework. The signals are characterized by an existence of very low-energy tau leptons in the final state due to small mass difference between stau_1 and chi_1 (5-15 GeV). We study the accuracy of the mass difference measurement with a 1^deg active mask to reduce a huge SM two-photon background.

description: The research field is marketing of quality food products for the introduction and promotion of innovative and differentiating products in distribution places far and culturally different by the country of origin/production. In an international trade context, environmental elements (e.g. the introduction of organic agriculture) and the role of the country of origin/production could influence the consumers’ perception of the distribution places. This study is aimed at deepening the knowledge about European consumer attitudes towards Thai organic rice and tapioca. In particular, the purpose was to explore relevant attributes for the quality product perception, motivations for purchasing, limiting factors, reasonable price brackets, trust elements. In this first phase of research, a qualitative approach was used. Four focus groups were administered (in Germany, in Greece, in Italy and in Scotland) by one or two investigators and the participants were recruited using a convenience sampling method (6-8 persons each). The discussions were recorded, transcribed and analysed through a qualitative approach. Finally, an exhaustive list of semantic categories was created, explained and supported by parts of the discussions. Participants still do not know much about these products, especially about tapioca. They tend to favour the product’s nutritional aspects, followed by its taste and smell, which in any case were not deemed satisfactory; however, they want also that a series of social and environmental benefits are satisfied. In general, Thai organic rice is perceived as a “different type” of rice and tapioca as a “new product”. The most important critical issues affecting participant’s opinions include: the lack of trust in the certification process by foreign countries and the low attitude towards trying food novelties seemed due to a sense of loyalty to (or affection for) local food traditions. One of the most important trust elements is represented by the brand of the distributor, the producer and the EU and national certification bodies; in particular, participants associate some parameters of guarantee and safety to brand’s name. The information obtained could be useful in further exploring of this topic and it needs to be tested with a quantitative approach.
An application of the renormalization group to the calculation of the vacuum decay rate in flat and curved space-time

description: I show that an application of renormalization group arguments may lead to significant corrections to the vacuum decay rate for phase transitions in flat and curved space-time. It can also give some information regarding its dependence on the parameters of the theory, including the cosmological constant in the case of decay in curved space-time.

description: This study develops a methodology to quantify the combined effects of two major nontariff barriers (NTBs), sanitary and phytosanitary (SPS) measures and customs and administrative procedures. We employ a constant elasticity of substitution (CES) utility function with factor-augmenting technical progress to incorporate changes in the quality of goods. We then estimate the effects of these two NTBs in the Japanese cut flower market. Results show that estimates of SPS are biased without considering product quality changes caused by the customs and administrative procedures for highly perishable agricultural products. If these Japanese NTBs were removed, findings suggest there would be a significant increase in cut flower imports by Japan.

description: Investigation of isotope effects on superconducting transition temperature (Tc) is one of the useful methods to examine whether electron-phonon interaction is essential for pairing mechanisms. The layered BiCh2-based (Ch: S, Se) superconductor family is a candidate for unconventional superconductors, because unconventional isotope effects have previously been observed in La(O,F)BiSSe and Bi4O4S3. In this study, we investigated the isotope effects of 32S and 34S in the high-pressure phase of (Sr,La)FBiS2, which has a monoclinic crystal structure and a higher Tc of 10 K under high pressures, and observed conventional-type isotope shifts in Tc. The conventional-type isotope effects in the monoclinic phase of (Sr,La)FBiS2 are different from the unconventional isotope effects observed in La(O,F)BiSSe and Bi4O4S3, which have a tetragonal structure. The obtained results suggest that the pairing mechanisms of BiCh2-based superconductors could be switched by a structural-symmetry change in the superconducting layers induced by pressure effects.

description: The present study investigates linear and volatile (nonlinear) correlations of first-order autoregressive process with uncorrelated AR (1) and long-range correlated CAR (1) Gaussian innovations as a function of the process parameter ($θ$). In the light of recent findings \cite{jano}, we discuss the choice of CAR (1) in modeling daily temperature records. We demonstrate that while CAR (1) is able to capture linear correlations it is unable to capture nonlinear (volatile) correlations in daily temperature records.
