description: A more stable exchange rate benefits China, Malaysia and New Zealand due to lower inflation rates and Japan, the Philippines, New Zealand, South Korea and Thailand because of higher growth rates but produces negative results for South Korea in terms of higher inflation rates and China due to lower growth rates. More monetary independence is beneficial to Australia, Japan and Malaysia due to higher growth rates but generates adverse outcomes for China, Malaysia and South Korea because of higher inflation rates. More free capital mobility is helpful to Australia, China, Japan, New Zealand, the Philippines and Singapore due to lower inflation rates or higher growth rates but yields negative outcomes for Thailand due to higher inflation rates. More exchange rate stability reduces output volatility for China, Indonesia, the Philippines, Singapore, South Korea and Thailand, decreases inflation volatility for Japan and New Zealand, increases inflation volatility for South Korea and Thailand, and has no impacts on inflation or output volatility for Australia and Malaysia. More monetary independence increases inflation volatility for China and output volatility for Singapore, and has no impacts on inflation or output volatility for other countries. More free capital mobility reduces inflation volatility for China, Japan, the Philippines, Singapore and South Korea and output volatility for China, Japan, South Korea, and has no impacts on Australia, Indonesia and New Zealand. Countries are expected to select a policy mix that would reduce inflation or output volatility. Hence, the effectiveness of these policies in reducing the inflation rate, increasing the growth rate and reducing inflation or output volatility should be considered in selecting a policy mix.

description: The identification of precursors of climatic phenomena has enormous practical importance. Recent work constructs a climate network based on surface air temperature data to analyze the El Niño phenomena. We utilize microtransitions which occur before the discontinuous percolation transition in the network as well as other network quantities to identify a set of reliable precursors of El Niño episodes. These precursors identify nine out of twelve El Niño episodes occurring in the period of 1979 to 2018 with a lead time varying from six to ten months. We also find indicators of tipping events in the data.

description: We report the first astronomical detection of the CF+ (fluoromethylidynium) ion obtained by recent observations of its J = 1 - 0 (102.6 GHz), J = 2 - 1 (205.2 GHz), and J = 3 - 2 (307.7 GHz) pure rotational emissions toward the Orion Bar. Our search for CF+, carried out using the IRAM 30m and APEX 12m telescopes, was motivated by recent theoretical models that predict CF+ abundances of a few x E-10 in UV-irradiated molecular regions where C+ is present. The measurements confirm the predictions. They provide support for our current theories of interstellar fluorine chemistry, which suggest that hydrogen fluoride should be ubiquitous in interstellar gas clouds.

description: We study the 2D Ising model on a square lattice with additional non-equal diagonal next-nearest neighbor interactions. The cases of classical and quantum (transverse) models are considered. Possible phases and their locations in the space of three Ising couplings are analyzed. In particular, incommensurate phases occurring only at non-equal diagonal couplings, are predicted. We also analyze a spin-pseudospin model comprised of the quantum Ising model coupled to XY spin chains in a particular region of interactions, corresponding to the Ising sector's super-antiferromagnetic (SAF) ground state. The spin-SAF transition in the coupled Ising-XY model into a phase with co-existent SAF Ising (pseudospin) long-range order and a spin gap is considered. Along with destruction of the quantum critical point of the Ising sector, the phase digram of the Ising-XY model can also demonstrate a re-entrance of the spin-SAF phase. A detailed study of the latter is presented. The mechanism of the re-entrance, due to interplay of interactions in the coupled model, and the conditions of its appearance are established. Applications of the spin-SAF theory for the transition in the quarter-filled ladder compound NaV2O5 are discussed.

description: The work highlights the importance of directional spreading effects on wave overtopping estimation in shallow and mild sloping foreshores. Wave short-crestedness leads, in general, to a reduction of mean overtopping discharges on coastal structures. In the present work, the case of a sea dike with gentle foreshore in very and extremely shallow water conditions is analysed. Physical model tests have been carried out in order to investigate the effect of directional spreading on overtopping and incident wave characteristics. In the present experimental campaign, the effect of wave spreading has only been investigated for perpendicular wave attack. Results show that directional spreading is proved to cause a reduction of average discharge of sea dikes with gentle and shallow foreshore. Expressions for the reduction factor for directional spreading are derived, fitted on the tested database. The use of this reduction factor leads to more accurate prediction and avoids overtopping overestimation, however reduction-factor formulations are overtopping-formula depending.

description: In this paper, we use data from Major League Baseball between 2000 and 2005 to illustrate how spatial econometric techniques can be used to directly model the interdependence of players. Specifically, we empirically examine the role of task specific human capital on earnings, by modeling player contracts as being determined by their performance, and the performance of other players with similar task specific human capital profiles. Our approach also provides an example to other researchers of a methodological approach to using spatial econometrics in settings where space is defined in ways other than spatial geography.
The X-ray Binary GRS 1741.9-2853 in Outburst and Quiescence

description: We report Chandra and XMM-Newton observations of the transient neutron star low-mass X-ray binary GRS 1741.9-2853. Chandra detected the source in outburst on 2000 October 26 at an X-ray luminosity of ~10^{36} erg/s (2--8 keV; 8 kpc), and in quiescence on 2001 July 18 at ~10^{32} erg/s. The latter observation is the first detection of GRS 1741.9-2853 in quiescence. We obtain an accurate position for the source of 17h 45m 2.33s, -28o 54' 49.7" (J2000), with an uncertainty of 0.7". GRS 1741.9-2853 was not detected significantly in three other Chandra observations, nor in three XMM-Newton observations, indicating that the luminosity of the source in quiescence varies by at least a factor of 5 between (< 0.9 - 5.0) \times 10^{32} erg/s (2--8 keV). A weak X-ray burst with a peak luminosity of 5 \times 10^{36} erg/s above the persistent level was observed with Chandra during the outburst on 2000 October 26. The energy of this burst, 10^{38} erg, is unexpectedly low, and may suggest that the accreted material is confined to the polar caps of the neutron star. A search of the literature reveals that GRS 1741.9-2853 was observed in outburst with ASCA in Fall 1996 as well, when the BeppoSAX WFC detected the three previous X-ray bursts from this source. The lack of X-ray bursts from GRS 1741.9-2853 at other epochs suggests that it produces bursts only during transient outbursts when the accretion rate onto the surface of the neutron star is about 10^{-10} M_sun/yr. A similar situation may hold for other low-luminosity bursters recently identified from WFC data.

We show that a bosonic version of the Kondo effect can occur in degenerate atomic Fermi gases near the Feshbach resonance. We also discuss how this bosonic Kondo effect can be observed experimentally.

description: We present measurements of the transient photoconductivity in pentacene single crystals using optical-pump THz-probe spectroscopy. We have measured the temperature and fluence dependence of the mobility of the photoexcited charge carriers with picosecond resolution. The pentacene crystals were excited at 3.0 eV which is above the bandgap of ~2.2 eV and the induced change in the far-infrared transmission was measured. At 30 K, the carrier mobility is mu ~ 0.4 cm^2/Vs and decreases to mu ~ 0.2 cm^2/Vs at room temperature. The transient terahertz signal reveals the presence of free carriers that are trapped on the timescale of a few ps or less, possibly through the formation of excitons, small polarons, or trapping by impurities.

description: IFRS 8 and its counterpart HKFRS 8 supersedes IAS 14 and HKAS 14 in 2006 to upgrade segment information disclosure that is increasingly becoming important financial information in investment decision making. There is little understanding of the changes in the quality of firms’ segment disclosure as a consequence of implementing the new standard in Hong Kong’s unique political and economic environment. This study attempts to document the usefulness of segment information disclosure by Hong Kong listed firms as a consequence of implementing HKIFRS 8. The study employs the value relevance of accounting information theory as a measure of usefulness of segment disclosure where segmental data are analysed by the portfolio return approach and regression analysis. The purposive sampling method is used to obtain samples from Hong Kong listed firms. The study results indicate that implementation of HKIFRS 8 has improved the usefulness of segment information disclosed by Hong Kong listed firms.

description: A total set of $n$ states $|i\rangle$ and the corresponding projectors $Π(i)=|i\rangle \langle i|$ are considered, in a quantum system with $d$-dimensional Hilbert space $H(d)$. A partially known density matrix $ρ$ with given $p(i)={\rm Tr}[ρΠ(i)]$ (where $i=1,...,n$ and $d\le n\le d^2-1$) is considered, and its ranking permutation is defined. It is used to calculate the Choquet integral ${\cal C}(ρ)$ which is a positive semi-definite Hermitian matrix. Comonotonicity is an important concept in the formalism, which is used to formalise the vague concept of physically similar density matrices. It is shown that ${\cal C}(ρ)/{\rm Tr}[{\cal C}(ρ)]$ is a density matrix which is a good approximation to the partially known density matrix $ρ$.

description: This study examines the feasibility of Brazilian ethanol dealers using the U.S. ethanol futures contracts as a price-risk management vehicle. This application is appropriate given that the U.S. and Brazil are the world’s largest and second largest ethanol producers. This specific application is part of a larger consideration as to how U.S. futures markets perform for hedging international commodities. This study considers the reasons why U.S. ethanol contracts might and might not work as hedging vehicles for Brazilian ethanol inventories prior to conducting an empirical investigation. Our empirical hedge ratio model formulates three components of price risk for international users of U.S. futures markets. These are (1) the risk of commodity price change given the initial currency exchange rate, (2) the risk of exchange rate change, given the commodity’s initial price, and (3) the risk of covariation between the commodity’s price and the currency exchange rate. Based on these sources of price risk, the hedging portfolio consists of the U.S. ethanol futures contract and the Brazilian real futures contract. Our analysis reveals that the U.S. ethanol futures contract provides little price-risk protection for Brazilian ethanol holder while the Brazilian real futures contract offers some protection. In contract, we present results from crude oil futures markets in which the U.S. crude oil futures contract gives the bulk of price risk protection and the currency futures contract provides much less. We conclude (1) that the ethanol findings are not universal and depend on the provisions of the U.S. ethanol futures contract and (2) the contracts traded on the Brazilian futures exchange do not compete directly with the U.S. contracts.

description: We investigate the second-order gravitational scalar perturbations for a barotropic fluid. We derive the effective energy-momentum tensor described by the quadratic terms of the gravitational and the matter perturbations. We show that the second-order effective energy-momentum tensor is gauge dependent. We impose three gauge conditions (longitudinal, spatially-flat, and comoving gauges) for dust and radiation. The resulting energy-momentum tensor is described only by a gauge invariant variable, but the functional form depends on the gauge choice. In the matter-dominated epoch with dust-like fluid background, the second-order effective energy density and pressure of the perturbations evolve as 1/a^2 in all three gauge choices, like the curvature density of the Universe, but they do not provide the correct equation of state. The value of this parameter depends also on the gauge choice. In the radiation-dominated epoch, the perturbations in the short-wave limit behave in the same way as the radiation-like fluid in the longitudinal and the spatially-flat gauges. However, they behave in a different way in the comoving gauge. As a whole, we conclude that the second-order effective energy-momentum tensor of the scalar perturbation is strictly gauge dependent.

description: The poor and vulnerable tend to be increasingly exposed to natural hazards like landslides. Land markets are one of the channels through which farmers get exposed to such hazards. This paper investigates the consequences of land transactions for the (un)equal distribution of exposure to landslide risk and of total land holdings in a rural area in Western Uganda. We propose and empirically test a mechanism through which land holdings and exposure to landslide risk evolves over a farmer’s lifetime. A structured household survey and detailed information on land transaction as well as georeferenced information on plots was used to construct a panel dataset of land transactions. Regressions with household fixed effects were run to identify how landholdings and exposure to landslide susceptibility evolves over a farmer’s lifetime. We find that farmers that are initially more exposed to landslides manage to reduce their average exposure to some extent by acquiring plots outside landslide prone areas. This goes at a cost, as farmers that are initially highly exposed acquire land more slowly than farmers that have a lower exposure on their first plot. Over a lifetime, in our case study, land transactions therefore have a somewhat levelling effect on inequality in exposure to landslide susceptibility, but increase the inequality in land ownership. As such, one of the ways through which unequal risk exposure contributes to propagating inequality in total land ownings is theoretical and empirically identified.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Using a large acceptance fast PbF_2 calorimeter with a solid angle of ΔΩ= 0.62 sr the A4 experiment is the first parity violation experiment to count individual scattering events. The measured asymmetry is A_{phys} =(-5.44 +- 0.54_{stat} +- 0.27_{\rm sys}) 10^{-6}. The Standard Model expectation assuming no strangeness contributions to the vector form factors is $A_0=(-6.30 +- 0.43) 10^{-6}$. The difference is a direct measurement of the strangeness contribution to the vector form factors of the proton. The extracted value is G^s_E + 0.225 G^s_M = 0.039 +- 0.034 or F^s_1 + 0.130 F^s_2 = 0.032 +- 0.028.

description: Natural hazards have a large impact on household livelihoods worldwide, especially in the Global South. Yet, literature on the adoption of risk reduction measures at household level remains scattered and inconclusive. This study combines geographical data with an original cross-sectional household survey to investigate the relation between individual land use plans and both exposure to and experience with a natural hazard. Regressions are used to test the protection motivation theory (PMT) and to investigate the link between intentions to plant trees to reduce landslide risk and past experiences, actual exposure, perceived threat and perceived capacity to prevent the occurrence of landslides. The results show that respondents in our study area in Uganda are well aware of landslide risk and believe trees are effective in landslide susceptibility reduction. Yet, those farmers that would benefit most from reducing landslide susceptibility by planting trees have the lowest intention to do so. A low self-efficacy among exposed farmers is proposed to explain this result. This finding has important implications for disaster risk reduction and land use policies and leads to recommendations on how governments and development agents should communicate about landslide risk.

The model generalises that introduced by O. J. O' Loan and M. R. Evans [J. Phys. A. vol. 32 L99 (1999)]. We motivate the dynamical rules by microscopic sampling considerations. The model exhibits various flocking regimes: the alternating flock, the homogeneous flock and dipole structures. We investigate these regimes numerically and within a continuum mean-field theory.

title: Genome-based approaches for identification of avirulence genes in potato cyst nematodes
Creators: name: Varypatakis, Kyriakos
Publisher: name: University of St Andrews
Year: 2019

description: The use of natural resistance is the most effective way to control the potato cyst nematodes Globodera pallida and G. rostochiensis. Although pathotypes of the latter species can now be fully controlled, control of G. pallida is a real challenge because of the existence of multiple pathotypes with different virulence behaviour. Although the available resistance sources confer partial resistance only, such as that from Solanum vernei (Gpa5) and S. tuberosum ssp. andigena CPC2802 (H3), their use may drive strong selection towards virulence. Resistance operates through the detection of nematode-derived effectors by plant resistance (R) proteins. Upon recognition, immune responses are activated in plants and the recognised effectors are then characterised as avirulence (avr) proteins. The study of the effectors and avr genes can provide important information on the mechanisms underlying selection. Fortunately, the development of novel sequencing technologies and genomic tools have enabled us to gain better insight towards complex genomes, such as that of potato cyst nematodes. Here, long-read sequencing was used for the generation of a new, more complete G. pallida genome. Based on this, analysis of captured, targeted effector-encoding genomic regions from virulent populations selected on the above resistance sources showed the presence of up to 54 candidate effectors that may determine virulence on these resistance sources. By cross-referencing those with the candidates identified from the re-sequencing of the same populations, 3 high-confidence candidate avr genes were listed. In parallel, the analysis of their allele frequencies and SNP distribution revealed that many potential effector genes are located within genomic “islands”, which are all selected on a specific resistance. This organisation is believed to facilitate selection evolution and host adaptation. Lastly, the G. rostochiensis candidate effector g13394 was cloned from an avirulent and virulent to H1 population, and subsequently was functionally validated through Agrobacterium-mediated transient expression using two different methods.

description: Remote sensing observations, products and simulations are fundamental sources of information to monitor our planet and its climate variability. Uncovering the main modes of spatial and temporal variability in Earth data is essential to analyze and understand the underlying physical dynamics and processes driving the Earth System. Dimensionality reduction methods can work with spatio-temporal datasets and decompose the information efficiently. Principal Component Analysis (PCA), also known as Empirical Orthogonal Functions (EOF) in geophysics, has been traditionally used to analyze climatic data. However, when nonlinear feature relations are present, PCA/EOF fails. In this work, we propose a nonlinear PCA method to deal with spatio-temporal Earth System data. The proposed method, called Rotated Complex Kernel PCA (ROCK-PCA for short), works in reproducing kernel Hilbert spaces to account for nonlinear processes, operates in the complex kernel domain to account for both space and time features, and adds an extra rotation for improved flexibility. The result is an explicitly resolved spatio-temporal decomposition of the Earth data cube. The method is unsupervised and computationally very efficient.We illustrate its ability to uncover spatio-temporal patterns using synthetic experiments and real data. Results of the decomposition of three essential climate variables are shown: satellite-based global Gross Primary Productivity (GPP) and Soil Moisture (SM), and reanalysis Sea Surface Temperature (SST) data. The ROCK-PCA method allows identifying their annual and seasonal oscillations, as well as their non-seasonal trends and spatial variability patterns.

description: In 2011, the largest Brazilian states to produce table grapes were Pernambuco and São Paulo. The region of Jales, a city located in the northwestern region of São Paulo, is the largest producer of fine table grapes. In this region, producers work exclusively with wholesalers (CEAGESP), passing through an intermediary called mateiro. In order to verify the importance of this intermediary, the objective of the research has been to analyze and understand the functioning of institutional arrangements used by grape growers in the region of Jales to market their production. It was used a model that combines formal and informal institutions with the model of Transaction Cost Economics (TCE). A questionnaire was conducted in April 2008 with 6.2% of producers of the region of Jales and 12.5% of the purchasers of table grapes. The sampling was non-probabilistic. Hybrid arrangements are recommended, with necessity of guarantees for the producers. Nevertheless, formal contracts do not work well with small producers, as they do not know the wholesalers, increasing the difficulty of establishing informal guarantees. Producers considered their products as delivered to the mateiros, with whom they established lasting relationships of trust. In conclusion, the mateiro is the main actor between producers and wholesalers and acts as an independent agent, although employee of the wholesaler. Relations between farmers and mateiros are based on the existence of social capital, which allows the creation of informal guarantees and the reduction of transaction costs.

description: This article is the result of an intellectual and empirical effort that sought to unravel the main relations between interorganizational cooperation activities and the creation of social innovations. The aim of the study was to discursively identify which and how are established the main Interorganizational cooperation relations, social innovations and Fair Trade/Sustainability initiatives developed by small organic food producers in southern Minas Gerais, Brazil. The theoretical axes of the work were based on discussions regarding Interorganizational Relations and Cooperation on Social Innovations and Fair Trade. As for the methodology, the fieldwork was conducted between November 2013 and January 2014. Seventeen interviews were conducted by means of Participatory Rapid Assessment that were later transcribed and analyzed in light of Critical Discourse Analysis. The survey results pointed to multiple formats of cooperation in intra and inter-organizational scenarios and to low levels of domestic competition. Cooperative relations among farmers were prior to the Fair Trade certification establishment. Furthermore, it was evident that Fair Trade can be understood as Social Innovation, however, the data shows some discursive inconsistencies related to certification agencies.

description: The present study analyzed total coffee exports from Brazil, Colombia and Peru. The choice of these three countries for analysis was due to the fact that they are the most expressive in South America, concerning international coffee trade. The period of analysis ranges from 1994 to 2013. The objective of the study was to verify the gains and/or losses of competitiveness in the global trade, as well as identify the main sources for growth and/or drop in the export of these countries. We employed the second level Constant Market Share (CMS) model and the Revealed Comparative Advantages (RCA) index. In the results, we noted that Brazil and Peru were able to increase their participation in the global coffee market, however, participation by Colombia decreased. We also verify that Brazil and Peru presented competitiveness gain in the international coffee market, which did not occur for Colombia.
In Search of a Hero: Morris & Company's Holy Grail Tapestries and the Arthurian Revival

description: This thesis analyzes the conception and production of the Holy Grail tapestries (1890-1894), a cycle of six narrative panels and six verdures designed by William Morris and Edward Burne-Jones and woven by artisans employed by Morris & Company in their Merton Abbey workshops. The tapestries, which depict the Arthurian legend of the search for the Holy Grail, yield insights into Morris and Burne-Jones’s particular conception of medievalism, and thus shed new light on Pre-Raphaelite revivalism. I argue that the Holy Grail tapestries represent the pinnacle of Morris & Company production, and of Morris’s career, because they allowed Morris to realize his longtime ambition to create a monumental tapestry cycle. The project exemplified the paradoxes at the heart of Morris & Company, both in terms of the circumstances of the commission and the manner in which the tapestries were produced. I also connect the subject of the tapestries with the identity of their patron, William Knox D’Arcy. I contend that Morris and Burne-Jones, who made their distaste for D’Arcy clear in correspondence about the project, used the ideals of masculine nobility represented in Arthurian legend to subtly critique the patron.

description: We consider the resolvent of a second order differential operator with a regular singularity, admitting a family of self-adjoint extensions. We find that the asymptotic expansion for the resolvent in the general case presents unusual powers of $λ$ which depend on the singularity. The consequences for the pole structure of the $ζ$-function, and the small-$t$ asymptotic expansion of the heat-kernel, are also discussed.

description: The spectrum of stars in the submillimeter to centimeter wavelength range remains poorly constrained due to a lack of data for most spectral types. An accurate characterization of stellar emission in this regime is needed to test stellar atmosphere models, and is also essential for revealing emission associated with unresolved circumstellar debris. We present ALMA observations of the three nearby, main-sequence, debris-poor, F-type stars $γ$ Lep, $γ$ Vir A, and $γ$ Vir B at 0.87 and 1.29 millimeters. We use these data to constrain semi-empirical atmospheric models. We discuss the atmospheric structure of these stars, explore potential short term variability, and the potential impact on debris disk studies. These results are part of an ongoing campaign to obtain long wavelength observations of debris-poor stars, entitled Measuring the Emission of Stellar Atmospheres at Submillimeter/millimeter wavelengths (MESAS).

description: In this note we clarify the relationship between the local and global definitions of dual pairs in Poisson geometry. It turns out that these are not equivalent. For the passage from local to global one needs a connected fiber hypothesis (this is well known), while the converse requires a dimension condition (which appears not to be known). We also provide examples illustrating the necessity of the extra conditions.
