description: This paper is concerned with uniform convergence in the multiplicative ergodic theorem on aperiodic subshifts. If such a subshift satisfies a certain condition, originally introduced by Boshernitzan, every locally constant SL(2,R)-valued cocycle is uniform. As a consequence, the corresponding Schrödinger operators exhibit Cantor spectrum of Lebesgue measure zero. An investigation of Boshernitzan's condition then shows that these results cover all earlier results of this type and, moreover, provide various new ones. In particular, Boshernitzan's condition is shown to hold for almost all circle maps and almost all Arnoux-Rauzy subshifts.

description: Developing a sustainable and resilient agribusiness sector is fundamental if Australia is to capture the value of the opportunity presented the by the growing food and fibre needs of a global population expected to reach 9.8bn by 2050 and 11bn by 2100. Key threats in the Australian context are an increasingly dynamic climate, changing demographics of regional Australia, economic factors related to currency fluctuations and the reality of being a price taker in a global market. While the current policy environment provides a number of mechanisms to support agribusinesses in mitigating these threats (including research and development investment, infrastructure investment, action to increases access to and competitiveness of markets as well as a suite of agricultural welfare options), it does not contemplate the relative readiness of individuals and businesses to act on the interventions of government. This paper proposes the adoption of the capabilities approach (CA) to refocus the policy framework and environment to prioritise the delivery of outcomes that are valued by individuals and businesses. A conceptual model is proposed to support the development, design and evaluation of future agribusiness policy. Fundamental to the conceptual model is the recognition of the central focus on the achievement of outcomes valued by agribusinesses, when considered within the constraints of the resource base, the capabilities of agribusiness owners to achieve the valued outcomes as well as the external factors required to aid in the conversion of the resources to valued outcomes.

description: The $ω$ and $ϕ$ mesons dominantly decay outside the nucleus because the decay-lengths of them are much larger than the dimension of the nucleus. Therefore, the medium modification of the above mesons is studied through their absorption in the nucleus. CLAS collaboration at Jefferson Laboratory (Jlab) has investigated the absorption of the $ω$ and $ϕ$ mesons by measuring the nuclear transparency ratios for them in the $γA \to ω(ϕ) X \to e^+e^-X$ reaction. The nuclear transparency ratios for both $ω$ and $ϕ$ mesons in the above reactions have been calculated, and those are compared with the experimental findings, reported from Jlab, to estimate the $ω$ meson nucleon and $ϕ$ meson nucleon cross sections in the nucleus.

description: In this paper, the investigation on the structure and molecular interactions in the binary systems containing aniline and 1-alkanol (1-pentanol up to 1-decanol) was performed in the framework of Kirkwood-Buff (KB) integrals and experimental techniques. The interpretation of obtained parameters shows that in binary mixtures with shorter chain alcohols, unlike molecules tend to form strong interactions, while increasing in the carbon atom of 1-alkanols reduces the strength of bonds and tendency of the heterogeneous molecules to stay along side. Mixtures structure was studied using the concentration-concentration structure factor, SCC(0). Results from the application of this parameter show that the heterocoordination occurs in solutions involving 1-pentanol up to 1-heptanol, while for mixtures containing 1-octanol to 1-decanol, homocoordination is predominant. Also, the chemical short-range order parameter, α′which is an important function to understand the complex formation and phase segregation in the liquid mixtures was obtained and discussed for mentioned mixtures.

description: In an ongoing programme to identify a sample of high z DLA galaxies we have found the long sought for case of a Ly-alpha emitter seen in the centre of a broad DLA trough. This is the predicted `textbook case' of an intervening DLA galaxy if DLA galaxies are small, but would not be expected if intervening high redshift DLA galaxies have large gaseous disks. The Ly-alpha flux is 5.4{+2}{-0.8} * 1e-17 ergs/s/cm2 similar to what has been found in previously known high z DLA galaxies. The impact parameter is found to be 0.3+-0.3 arcsec. This is smaller than what was found in previous cases but still consistent with random sight-lines through absorbers with mean impact parameter ~1 arcsec. Of the 24 DLAs targeted in the NICMOS imaging survey five have now been identified as Ly-alpha emitters. The DLA galaxies with detected Ly-alpha emission tend to have higher interstellar metallicities than those with undetected Ly-alpha emission. This is plausibly explained as a consequence of a positive correlation between the Ly-alpha line luminosities of the galaxies and their metallicities, although the present sample is too small for a definitive conclusion. The available observations of high-redshift DLA galaxies are also consistent with a negative correlation between Ly-alpha equivalent widths and metallicities, as seen in nearby star-forming galaxies and usually attributed to the preferential absorption of Ly-alpha photons by dust grains.

To understand the molecular interactions of solute–solvent, measured excess properties such as the excess molar volume, VmE, excess isentropic compressibility, κsE, excess speeds of sound, uE, excess molar isentropic compressibility, Ks,mE, thermal expansion coefficient, αp, excess thermal expansion coefficient, αpE were calculated and fitted using the Redlich–Kister equation. For better understanding, also calculated partial molar volumes/isentropic compressibilities, and their excess properties at infinite dilution were measured. These parameters have been used to understand the interactions in the mixtures qualitatively. The experimental VmE findings were compared through the usage of theoretical model developed by Prigogine–Flory–Patterson (PFP).

description: Ground and isomeric states of the neutron-deficient odd-$A$ isotopes $^{183}$Hg, $^{185}$Hg, and $^{187}$Hg are described from a microscopic calculation based on a self-consistent, axially-deformed Hartree-Fock mean field with the Skyrme functional and pairing within BCS approximation. For each equilibrium shape and different odd-neutron states, results on mean square charge radii and magnetic dipole moments are given and analyzed in the context of their sensitivity to the nuclear deformation and to the spin and parity. Spin-isospin correlations within proton-neutron quasiparticle random phase approximation are then introduced in the nuclear states to obtain the distributions of Gamow-Teller strength and the $β^+/EC$ half-lives of these isotopes, whose measurements are planned at ISOLDE-CERN using total absorption gamma-ray spectroscopy techniques.

description: Estimating the economic value of clean air is of significance to both policymakers and private individuals but its quantification has proved difficult. Of the different valuation approaches used, the classic hedonic theory predicts a negative relationship between air quality and housing prices. Existing attempts to quantify this nexus is plagued by problems of endogeneity, mainly arising from omitted variables that confound air pollution with other determinants of housing prices. We employ a regression discontinuity (RD) design to estimate the impact of air pollution on house prices across a river that demarcates regions with and without coal-fired heating emanating from the Huai River Policy. This policy was decreed by the Chinese government in the 1950s that allowed burning of coal at subsidised prices for indoor heating to only the north of the Huai River. Employing quasi-experimental variation in particulate matter of 10 micrometres or less in aerodynamic diameter (PM10) generated by this arbitrary policy and regression discontinuity (RD) design based on distance from Huai River, we estimate the local average treatment effect (LATE) to provide new evidence on the capitalization of PM10 air pollution into housing values. By using panel data of 30 large cities on either side of the river for the period 2006 to 2015, we found that 1 μg/m3 reduction in average PM10 results in an approximately 1 percent increase in housing prices. The results are robust to using parametric and nonparametric estimation methods and adjustment to a rich set of covariates.

description: We investigate the low-temperature properties of a ultracold gas made of bosonic alkali-metal atoms with finite-range interaction under the effect of a disordered environment. The statistical characterization of the disorder is investigated within an effective-field-theory formalism for a generic spatial dimension $d$. Moving to $d=3$, where all the arising divergences are properly regularized, we focus on the depletion of both the condensate and superfluid densities. At zero temperature we obtain meaningful analytical formulas for the condensate fraction and the superfluid fraction which take into account the interplay among scattering length, effective range, and disorder strength.

Model invariance when estimating random parameters with categorical variables

Publisher: name: Unknown
Year: 2019
Subjects: Research Methods/ Statistical Methods

description: This paper shows that econometric models that include categorical variables are not invariant to choice of ‘base’ category when random parameters are estimated, unless they are allowed to be correlated. We show that the lack of invariance can lead to significant increases in Type I errors, and a misrepresentation of the preferences of respondents. We hypothesis that these biases may influence the economic policy implications of published models that contain this error, which we show in two empirical applications. However, it is impossible to identify the degree of the error in the many published papers we identify that contain this effect, without re-estimating the models correctly.

description: We study isospin-1 P-wave $ππ$ scattering in lattice QCD with two flavours of O($a$) improved Wilson fermions. For pion masses ranging from $m_π=265$ MeV to $m_π=437$ MeV, we determine the energy spectrum in the centre-of-mass frame and in three moving frames. We obtain the scattering phase shifts using Lüscher's finite-volume quantisation condition. Fitting the dependence of the phase shifts on the scattering momentum to a Breit-Wigner form allows us to determine the resonance parameters $m_ρ$ and $g_{ρππ}$. By combining the scattering phase shifts with the decay matrix element of the vector current, we calculate the timelike pion form factor, $F_π$, and compare the results to the Gounaris-Sakurai representation of the form factor in terms of the resonance parameters. In addition, we fit our data for the form factor to the functional form suggested by the Omnès representation, which allows for the extraction of the charge radius of the pion. As a further application, we discuss the long-distance behaviour of the vector correlator, which is dominated by the two-pion channel. We reconstruct the long-distance part in two ways: one based on the finite-volume energies and matrix elements and the other based on $F_π$. It is shown that this part can be accurately constrained using the reconstructions, which has important consequences for lattice calculations of the hadronic vacuum polarisation contribution to the muon anomalous magnetic moment.

description: We solve robust optimization problem and show the example of the market model for which the worst case measure is not a martingale measure. In our model the instantaneous interest rate is determined by the Hull-White model and the investor employs the HARA utility to measure his satisfaction.To protect against the model uncertainty he uses the worst case measure approach. The problem is formulated as a stochastic game between the investor and the market from the other side. PDE methods are used to find the saddle point and the precise verification argument is provided.

description: Child undernutrition, particularly stunting, wasting and micronutrient deficiencies, remains a major health concern in rural communities in Vietnam. While literature suggests leveraging agriculture to improve child nutrition via agricultural diversification, market engagement, and women empowerment, very few studies have explored how smallholder vegetable production can influence child nutrition outcomes. The present paper tries to fill this gap using a nutrition-centred approach that examines the impacts of vegetable production diversity, market access, and market participation at the household level. We use a cross-sectional household dataset that we collected in 2016 in Northwest Vietnam covering 234 children aged 6 to 60 months. We estimate several regression models using three-stage least squares (3SLS), ordinary least squares (OLS), logistic regression, and seemingly unrelated regression (SUR), in their most appropriate settings and in a comparative manner to explain variations in several nutrition outcome measures, including height-for-age (HAZ), weight-for-height (WHZ), and weight-for-age (WAZ) Z-scores, as well as three other measures (stunting, wasting, and underweight). Our results suggest that smallholder vegetable production has a significant indirect effect on child nutrition via market participation. Market participation is an important factor in improving girls’ HAZ and WHZ, and in reducing the probabilities of boys being stunted and underweight. It is implied that additional income from selling vegetables allows households to purchase nutritious food, which is likely to have a positive impact on child nutrition outcomes.

description: We assess the status of big-bang nucleosynthesis (BBN) in light of the final Planck data release and other recent developments, and in anticipation of future measurements. Planck data fix the cosmic baryon density to 0.9% precision, and determine the helium abundance and effective number of neutrinos with precision approaching that of astronomical and BBN determinations respectively. In addition, new high-redshift measurements give D/H to better precision than theoretical predictions, and new Li/H data reconfirm the lithium problem. We present new ${}^{7}{\rm Be}(n,p){}^{7}{\rm Li}$ rates using new neutron capture measurements; we have also examined the effect of proposed changes in the $d(p,γ){}^{3}{\rm He}$ rates. Using these results we perform a series of likelihood analyses. We assess BBN/CMB consistency, with attention to how our results depend on the choice of Planck data, as well as how the results depend on the choice of non-BBN, non-Planck data sets. Most importantly the lithium problem remains, and indeed is more acute given the very tight D/H observational constraints; new neutron capture data reveals systematics that somewhat increases uncertainty and thus slightly reduces but does not essentially change the problem. We confirm that $d(p,γ){}^{3}{\rm He}$ theoretical rates brings D/H out of agreement and slightly increases 7Li; new experimental data are needed at BBN energies. Setting the lithium problem aside, we find the effective number of neutrino species at BBN is $N_ν= 2.86 \pm 0.15$. Future CMB Stage-4 measurements promise substantial improvements in BBN parameters: helium abundance determinations will be competitive with the best astronomical determinations, and $N_{\rm eff}$ will approach sensitivities capable of detecting the effects of Standard Model neutrino heating of the primordial plasma.

description: Let K be a field of characteristic 0. We consider linear equations a1*x1+...+an*xn=1 in unknowns x1,...,xn from G, where a1,...,an are non-zero elements of K, and where G is a subgroup of the multiplicative group of non-zero elements of K. Two tuples (a1,...,an) and (b1,...,bn) of non-zero elements of K are called G-equivalent if there are u1,...,un in G such that b1=a1*u1,..., bn=an*un. Denote by m(a1,...,an,G) the smallest number m such that the set of solutions of a1*x1+...+an*xn=1 in x1,...,xn from G is contained in the union of m proper linear subspaces of K^n. It is known that m(a1,...,an,G) is finite; clearly, this quantity does not change if (a1,...,an) is replaced by a G-equivalent tuple. Gyory and the author proved in 1988 that there is a constant c(n) depending only on the number of variables n, such that for all but finitely many G-equivalence classes (a1,...,an), one has m(a1,...,an,G)< c(n). It is as yet not clear what is the best possible value of c(n). Gyory and the author showed that c(n)=2^{(n+1)!} can be taken. This was improved by the author in 1993 to c(n)=(n!)^{2n+2}. In the present paper we improve this further to c(n)=2^{n+1}, and give an example showing that c(n) can not be smaller than n.

Considering cross-hedging in futures market, we investigate price linkages and volatility spillover among hops, barley, and other selected agricultural products. Based on previous studies, hard red wheat, soft red wheat and corn are selected as the grain inputs most relevant to the brewery industry. We use monthly price data and nearby future price data, estimate VAR and VEC models to capture short and long-run price relationships, then estimate a BEKK-ARCH model to analyse the volatility spillover effects. The empirical results provide evidence supporting bidirectional long-run price relationship between hops and barley, but only short-run relationships between hops and other grain inputs. For barley, the long-run price relationships are found in all barley related pairs, e.g. barley-soft red wheat, barley-hard red wheat and barley-corn. Moreover, we identify volatility spillover transmission from soft red wheat and barley to hops. And soft red wheat, hard red wheat and corn exhibit volatility spillover effects on barley. In addition, the in-sample prediction shows the great fitting performance. This provides the empirical evidence to cross hedge the price risk of hops and barley using soft red wheat, hard red wheat and corn in brewery industry for the future studies.

description: Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrmion creating a magnetic flux quantum h/e. The control and understanding of topological properties in nanostructured materials is the subject of immense interest for both fundamental science and technological applications, especially in spintronics. In this work, the electron-transport properties and spin structure of exchange-coupled cobalt nanoparticles with an average particle size of 13.7 nm are studied experimentally and theoretically. Magnetic and Hall-effect measurements identify topological phase transitions in the exchange-coupled cobalt nanoparticles and were used to discover a qualitatively new type of hysteresis in the topological Hall effect namely, Berry-phase hysteresis. Micromagnetic simulations reveal the origin of the topological Hall effect namely, the chiral domains, with domain-wall chirality quantified by an integer skyrmion number. These spin structures are different from the skyrmions formed due to Dzyaloshinskii Moriya interactions in B20 crystals and multilayered thin films, and caused by cooperative magnetization reversal in the exchange-coupled cobalt nanoparticles. An analytical model is developed to explain the underlying physics of Berry-phase hysteresis, which is strikingly different from the iconic magnetic hysteresis and constitutes one aspect of 21st-century reshaping of our view on nature at the borderline of physics, chemistry, mathematics, and materials science.

description: Does the extent of participation in global agriculture value chains accelerate structural transformation in countries? The rise of global value chains (GVCs) in agriculture has been a salient feature of the world economy over recent years. Despite their importance for the world economy, it is, however, unclear whether participation in GVCs leads the structural transformation--that is, the move from an economy primarily based on agriculture to an economy primarily based on manufacture, and then on service. In this paper, I investigate the impact of the participation of GVCs in the agricultural sector on structural transformation in countries by using cross-country panel data for 183 countries from 1990 to 2013. By using country-fixed effects, I find that in response to greater agricultural value chains participation, manufacturing employment remains stable, but employment in the services sector increases. In short, modern-day developing economies are leapfrogging manufacturing to directly develop their services sector through GVCs in agriculture. This result is strongly and significantly robust to all different model specifications with year fixed effects, regional-specific fixed effects, and time monotonicity. Also, by using alternative measures of structural transformation such as GDP shares by sectors or female employment shares, the results are still strongly robust. I measure the extent of agricultural GVCs by adopting the method Wang et al. (NBER, 2013) at the country level. I control for agricultural trade policies, domestic policy to agriculture, agricultural land areas, population, urban population growth, and demographic structure of countries. This is an important result as the evidence that agricultural GVCs participation has played a significant role in economic development in the world.

description: We introduce a family of matrix dilogarithms, which are automorphisms of C^N tensor C^N, N being any odd positive integer, associated to hyperbolic ideal tetrahedra equipped with an additional decoration. The matrix dilogarithms satisfy fundamental five-term identities that correspond to decorated versions of the 2 --> 3 move on 3-dimensional triangulations. Together with the decoration, they arise from the solution we give of a symmetrization problem for a specific family of basic matrix dilogarithms, the classical (N=1) one being the Rogers dilogarithm, which only satisfy one special instance of five-term identity. We use the matrix dilogarithms to construct invariant state sums for closed oriented 3-manifolds $W$ endowed with a flat principal PSL(2,C)-bundle rho, and a fixed non empty link L if N>1, and for (possibly "marked") cusped hyperbolic 3-manifolds M. When N=1 the state sums recover known simplicial formulas for the volume and the Chern-Simons invariant. When N>$, the invariants for M are new; those for triples (W,L,rho) coincide with the quantum hyperbolic invariants defined in [Topology 43 (2004) 1373-1423], though our present approach clarifies substantially their nature. We analyse the structural coincidences versus discrepancies between the cases N=1 and N>1, and we formulate "Volume Conjectures", having geometric motivations, about the asymptotic behaviour of the invariants when N tends to infinity.

description: The lowland rice industry in Laos experiences dry conditions regularly. Rice producers also face rising labour costs as the Lao economy grows. Much of the crop is consumed by the farm households who grew it. Between 1997 and 2012 ACIAR co-funded a set of three projects with the main outcomes being the development of rice varieties more tolerant of dry conditions and direct seeding technologies to replace traditional hand transplanting. Human capacity and scientific knowledge were other significant outcomes from the projects. Direct seeding allowed the release of family labour for other on- and off- farm and household activities. Assessing ACIAR’s contribution to the economic and social impacts from this set of projects was difficult because of the length of time since the projects began, because of the lack of data about the adoption of the technologies and because the University team funded by ACIAR were not the only research team working on these technologies. We focussed on estimating the economic impact of the two technologies applying welfare analysis in a farm level market model of the Lao rice industry and on describing gains in scientific capacity and knowledge. Potential social impacts from the releasing labour from transplanting were also described. Given the uncertainties created by inadequate data, care was taken to develop plausible causal pathways between project research activities and economic and social outcomes. The present value in 2017 of the investment in the three projects by ACIAR and partners was estimated to be $A14.1m (all monetary values in 2017 $AUD and applying ACIAR’s 5% discount rate). The present values in 2017 of the streams of measurable benefits from the adoption of more drought tolerant varieties and direct seeding technology were $A18.5m and $A44.1m respectively, for a total of $A62.6m. The net present value of these streams of benefits and costs in 2017 was $A48.5m. The benefit cost ratio was 4.44:1 and the internal rate of return was 16.0%. The modified internal rate of return, MIRR was 11.5% assuming that the net benefit stream can be reinvested through the life of the investment at a rate of 5%. By these three measures the set of three projects, whose impact has been assessed here, are likely to have been a good investment from ACIAR’s perspective. This conclusion is quite robust to the uncertainty surrounding our assumption about the rates of adoption of the technologies and the share of benefits from the two technologies attributable to the ACIAR projects. If both these parameters are halved (approximately) for both technologies, an unlikely scenario in our view, the investment in the projects still earns the required rate of return.

description: Six years on from the Fukushima nuclear power plant accident in Japan, some consumers still avoid purchasing foods from Fukushima prefecture even when their safety is scientifically guaranteed. Exploiting this situation, we demonstrate how the willingness-to-pay (WTP) approach can be misleading to analyze the demand for food that is stigmatized by some consumers. Conducting choice experiments for rice in Japan in 2016, we explicitly separate the consumers who excessively avoid Fukushima foods (no-tolerant consumers) from other ordinary consumers. We then investigate whether the WTP for Fukushima rice and the safety standard label are systematically different between the two types of consumers. We also examine how providing additional scientific information influences the WTP differently between the two types. We found that 33% of our sample were no-tolerant consumers, and their WTP for Fukushima rice was substantially lower than the market price while ordinary consumers WTP was higher than the market price. Without distinguishing the two types, the average WTP became lower than the market price even with the safety standard label, which misleadingly understated the value of Fukushima rice and the label. Lastly, we found little effect of providing additional scientific information on the WTP in both types. Acknowledgement :

description: This document is Help File and User Guide for free and open-source geographic information system (GIS) plug-in named PolyMorph-2D.jar. Written in Java™ programming language, the PolyMorph-2D plug-in can be used for morphometric analysis of vector-based two dimensional (2D) polygon features in OpenJUMP GIS software environment. PolyMorph-2D plug-in allows researchers from various earth and spatial science-related disciplines to compute morphometric parameters of 2D input vector features forming a polygon (i.e., a closed curve) which may represent outer boundaries of various natural and/or man-made entities that differ in size, shape, complexity and drawing scale (e.g., craters, sinkholes, cirques, drainage basins, land parcels, buildings, lakes, ponds, peaks, pits, playas, pockmarks, coral mounds, seamounts, landslides, drumlins, islands, atolls, granular materials, mineral crystals, fossils, etc.). The PolyMorph-2D plug-in provides a selected set of the most common morphometric parameters that are used in the earth and spatial science studies, as well as in others, such as biology, mathematics, computer science, etc.

description: We study the behavior of quasi-one-dimensional (quasi-1d) Bose gases by Monte Carlo techniques, i.e., by the variational Monte Carlo, the diffusion Monte Carlo, and the fixed-node diffusion Monte Carlo technique. Our calculations confirm and extend our results of an earlier study [Astrakharchik et al., cond-mat/0308585]. We find that a quasi-1d Bose gas i) is well described by a 1d model Hamiltonian with contact interactions and renormalized coupling constant; ii) reaches the Tonks-Girardeau regime for a critical value of the 3d scattering length a_3d; iii) enters a unitary regime for |a_3d| -> infinity, where the properties of the gas are independent of a_3d and are similar to those of a 1d gas of hard-rods; and iv) becomes unstable against cluster formation for a critical value of the 1d gas parameter. The accuracy and implications of our results are discussed in detail.
