description: This paper investigates a vector auto regression model, using the Johansen cointegration technique, and the autoregressive integrated moving average time series models to determine the better model for forecasting US tree nut prices over the period 1992-2006. The Johansen contegration test shows lack of long run relationship among pecan, walnut, and almond prices. As such, only autoregressive integrated moving average-type models were used in forecasting U.S. nut prices.

description: Although several institutional and management approaches that address the degradation of the rangelands have been tested in the dry areas of Central and West Asia and North Africa (CWANA), impact has been limited. Nonetheless, the development of National Action Plans to combat desertification highlights the interest of governments to tackle this issue. Payment for Environmental Services (PES) may be a viable policy option, though, to date, most PES programs have focused on the management of different resources (forests, watersheds). The purpose of this paper is to examine whether PES could be a viable option to promote sustainable rangelands management in the dry rangelands of CWANA. Specifically, it focuses on the scientific gaps and knowledge related to the local and global environmental services produced by rangelands and addresses questions related to the beneficiaries of these services. Institutional conditions necessary for the implementation of such schemes are discussed.

description: Η παρούσα διπλωματική εργασία διερευνά για ένα δείγμα εταιρειών της Ευρωζώνης, για τα έτη 2004-2019, τον τρόπο με τον οποίο η ποιότητα της Εταιρικής Διακυβέρνησης και οι μηχανισμοί της επιδρούν στην τάση των επιχειρήσεων να επιτυγχάνουν οριακούς στόχους κερδών, δηλαδή να χειραγωγούν τα κέρδη τους. Ως Εταιρική Διακυβέρνηση ορίζεται το σύνολο των κανόνων που συμβάλλει στην κατανομή των υποχρεώσεων αλλά και των δικαιωμάτων μεταξύ του διοικητικού συμβουλίου, των διευθυντών, των μετόχων και των υπόλοιπων ενδιαφερόμενων μερών και επεξηγεί τη διαδικασία λήψης αποφάσεων για εταιρικά ζητήματα, με σκοπό την αύξηση της αξίας της επιχείρησης. Η επίτευξη οριακών στόχων κερδών μεταφράζεται ως την επίτευξη οριακά θετικών κερδών ή ως τη διατήρηση των κερδών της προηγούμενης περιόδου ή ακόμη ως την επίτευξη των προβλέψεων των αναλυτών σχετικά με τα κέρδη. Επιπλέον, εξετάζεται η επίδραση της ποιότητας της Εταιρικής Διακυβέρνησης και των δεικτών που την καθορίζουν, στην επίτευξη οριακών στόχων κερδών για χώρες που δέχονται πίεση από το μακροοικονομικό τους περιβάλλον και για χώρες που το κλίμα της οικονομίας είναι πιο ευνοϊκό για τις ίδιες. Από την ανάλυση των αποτελεσμάτων των παλινδρομήσεων προκύπτει ότι η ισχυρή ποιότητα της Εταιρικής Διακυβέρνησης, όπως και οι περισσότεροι δείκτες που την αποτυπώνουν, μειώνουν τα κίνητρα των επιχειρήσεων να υιοθετούν πρακτικές που συμβάλλουν στη χειραγώγηση των κερδών. Τα ευρήματα δείχνουν επίσης, ότι οι χώρες που αντιμετωπίζουν οικονομικές δυσχέρειες παρουσιάζουν υψηλότερη τάση επίτευξης οριακών στόχων κερδών συγκριτικά με τις πιο οικονομικά ισχυρές χώρες, γεγονός που υποδηλώνει ότι οι μακροοικονομικές δυσκολίες συνδέονται με θετικό τρόπο με τη χειραγώγηση των κερδών.

description: Poverty reduction and sustainable land management are two objectives that most African countries strive to achieve simultaneously. In designing policies to achieve these objectives concurrently a clear understanding of their linkage is crucial. Yet there is only limited empirical evidence to demonstrate the linkage between poverty and land management in Africa. Using Uganda as a case study, this analysis seeks to better understand this linkage. We used several poverty measures to demonstrate the linkage between poverty and a number of indicators of sustainable land management. In general we found a strong linkage. The results for many poverty indicators give credence to the land degradation–poverty trap, although some indicators showed negative association with land degradation. These results suggest that certain poverty reduction strategies being implemented through agricultural modernization in Africa can achieve win-win-win outcomes, simultaneously increasing productivity, reducing poverty, and reducing land degradation. Examples of such strategies include promoting investments in soil and water conservation and agroforestry. Some strategies—such as road development, encouragement of nonfarm activities, and promotion of rural finance—appear to contribute to positive outcomes without significant tradeoffs. Other strategies are likely to involve trade-offs among different objectives. The presence of such trade-offs is not an argument for avoiding these strategies; rather it suggests the need to recognize and find ways to ameliorate such negative impacts where they occur. For example, incorporating teaching of the principles of sustainable agriculture and land management into educational curricula, and into the technical assistance approach of the National Agricultural Advisory Services and other organizations, is one important way of addressing such trade-offs. Investment in poverty reduction and agricultural modernization by itself is not sufficient to address the problem of land degradation in Uganda; it must be complemented by greater efforts to promote sustainable land management practices.
Leptonic New Force and Cosmic-ray Boosted Dark Matter for the XENON1T Excess

description: The recently reported excess in XENON1T is explained by new leptonic forces, which are free from gauge anomalies. We focus on two scenarios with and without dark matter. In Scenario #1, the gauge boson of gauged lepton number U(1)$_{L_e-L_j}$, $j=μ$ or $τ$ provides non-standard interaction between solar neutrino and electron that enhances the number of electron recoil events in the XENON1T detector. In Scenario #2, the new gauge boson exclusively couples to electron and dark matter, then cosmic-ray electrons can transfer their momenta to dark matter in halo. The boosted dark matter generates the electron recoil signals of ${\cal O}(1)$ keV. The dark matter, aided by the new gauge interaction, efficiently heats up a neutron star in our Galaxy more than $\sim1500$ K as a neutron star captures the halo dark matter. Therefore, we propose to utilize the future infrared telescope to test our scenario.

Well-to-Wheels Energy and Greenhouse Gas Emission Results and Issues of Fuel Ethanol
Creators: name: Wang, Michael Q.

Year: 2008
Subjects: Environmental Economics and Policy

description: The use of fuel ethanol in the United States has increased from fewer than 200 million gallons (gal) at the beginning of the US fuel ethanol program in 1980 to 6.5 billion gal in 2007. The recent federally adopted Energy Independence and Security Act of 2007 established the goal of 36 billion gal of biofuel use in the United States by 2022, of which 15 billion gal will be corn-based ethanol. In addition, the promotion of low-carbon fuel standards (LCFS) by California and several other states could help increased use of ethanol, especially cellulosic ethanol. In the United States, corn ethanol is produced through the fermentation of corn in dry and wet milling plants, most of which are located in the Midwest. In 2006, about 82% of the total US fuel ethanol was produced from dry milling plants, and the remaining 18% from wet milling plants (Renewable Fuels Association, 2007). Ethanol can be produced from cellulosic biomass through fermentation of cellulose and semicellulose. The US Department of Energy (DOE) has been undertaking extensive research and development (R&D) efforts for cellulosic ethanol technologies. Since 1997, Argonne National Laboratory has been evaluating the energy and emission effects of fuel ethanol relative to those of petroleum gasoline. In 1997, Argonne National Laboratory published its findings from an ethanol analysis conducted for the State of Illinois (Wang et al., 1997). With DOE support, Argonne National Laboratory has continued its efforts to analyze the effects of fuel ethanol (Wang et al., 1999a,b; Wang et al., 2003; Wu et al., 2005; and Wu et al., 2006). As fuel ethanol production and usage in the United States have rapidly expanded in the past several years, corn ethanol plant technologies have been evolving. In addition, while corn yield per acre continues to increase, concerns have been raised that increased corn farming could result in switches in crop farming in the United States and potential land use changes in other countries. These factors together could cause different energy and greenhouse gas (GHG) emission results for corn ethanol. This chapter presents Argonne National Laboratory’s updated energy and GHG emission results for fuel ethanol.

description: I discuss the trace of a heat kernel Tr[e^(-tA)] for compact fuzzy spaces. In continuum theory its asymptotic expansion for t -> +0 provides geometric quantities, and therefore may be used to extract effective geometric quantities for fuzzy spaces. For compact fuzzy spaces, however, an asymptotic expansion for t -> +0 is not appropriate because of their finiteness. It is shown that effective geometric quantities are found as coefficients of an approximate power-law expansion of the trace of a heat kernel valid for intermediate values of t. An efficient method to obtain these coefficients is presented and applied to some known fuzzy spaces to check its validity.

description: Two-dimensional (2D) post-transition metal chalcogenides (PTMC) have attracted attention due to their suitable band gaps and lower exciton binding energies, making them more appropriate for electronic, optical and water-splitting devices than graphene and monolayer transition metal dichalcogenides (TMDs). Of the predicted 2D PTMCs, GaSe has been reliably synthesized and experimentally characterized. Despite this fact, quantities such as lattice parameters and band character vary significantly depending on which density functional theory (DFT) functional is used. Although many-body perturbation theory (GW approximation) has been used to correct the electronic structure and obtain the excited state properties of 2D GaSe, and solving the Bethe-Salpeter equation (BSE) has been used to find the optical gap, we find that the results depend strongly on the starting wavefunction. In attempt to correct these discrepancies, we employed the many-body Diffusion Monte Carlo (DMC) method to calculate the ground and excited state properties of GaSe because DMC has a weaker dependence on the trial wavefunction. We benchmark these results with available experimental data, DFT [local-density approximation, Perdew-Burke-Ernzerhof (PBE), strongly constrained and appropriately normed (SCAN) meta-GGA, and hybrid (HSE06) functionals] and GW-BSE (using PBE and SCAN wavefunctions) results. Our findings confirm monolayer GaSe is an indirect gap semiconductor (Gamma-M) with a quasiparticle electronic gap in close agreement with experiment and low exciton binding energy. We also benchmark the optimal lattice parameter, cohesive energy and ground state charge density with DMC and various DFT methods. We aim to present a terminal theoretical benchmark for pristine monolayer GaSe, which will aide in the further study of 2D PTMCs using DMC methods.

description: Excited states of $^{129}$In populated following the $β$-decay of $^{129}$Cd were experimentally studied with the GRIFFIN spectrometer at the ISAC facility of TRIUMF, Canada. A 480-MeV proton beam was impinged on a uranium carbide target and $^{129}$Cd was extracted using the Ion Guide Laser Ion Source (IG-LIS). $β$- and $γ$-rays following the decay of $^{129}$Cd were detected with the GRIFFIN spectrometer comprising the plastic scintillator SCEPTAR and 16 high-purity germanium (HPGe) clover-type detectors. %, along with the $β$-particles were detected with SCEPTAR. From the $β$-$γ$-$γ$ coincidence analysis, 32 new transitions and 7 new excited states were established, expanding the previously known level scheme of $^{129}$In. The $\log ft$ values deduced from the $β$-feeding intensities suggest that some of the high-lying states were populated by the $ν0 g_{7/2} \rightarrow π0 g_{9/2}$ allowed Gamow-Teller (GT) transition, which indicates that the allowed GT transition is more dominant in the $^{129}$Cd decay than previously reported. Observation of fragmented Gamow-Teller strengths is consistent with theoretical calculations.

description: We present optical and near-infrared observations of SN~Ib~2019ehk. We show that it evolved to a Ca-rich transient according to its spectral properties and evolution in late phases. It, however, shows a few distinguishable properties from the canonical Ca-rich transients: a short-duration first peak in the light curve, high peak luminosity, and association with a star-forming environment. Indeed, some of these features are shared with iPTF14gqr and iPTF16hgs, which are candidates for a special class of core-collapse SNe (CCSNe): the so-called ultra-stripped envelope SNe, i.e., a relatively low-mass He (or C+O) star explosion in a binary as a precursor of double neutron star binaries. The estimated ejecta mass ($0.43 M_\odot$) and explosion energy ($1.7 \times 10^{50} $~erg) are consistent with this scenario. The analysis of the first peak suggests existence of dense circumstellar material in the vicinity of the progenitor, implying a CCSN origin. Based on these analyses, we suggest SN 2019ehk is another candidate for an ultra-stripped envelope SN. These ultra-stripped envelope SN candidates seem to form a subpopulation among Ca-rich transients, associated with young population. We propose that the key to distinguishing this population is the early first peak in their light curves.

description: Based on the holographic conjecture for superstrings on Dp-brane backgrounds and the dual (p+1)-dimensional gauge theory ($0\le p\le 4$) given in hep-th/0308024 and hep-th/0405203, we continue the study of superstring amplitudes including string higher modes ($n\ne 0$). We give a prediction to the two-point functions of operators with large R-charge J. The effect of stringy modes do not appear as the form of anomalous dimensions except for p=3. Instead, it gives non-trivial correction to the two-point functions for supergravity modes. For p=4, the scalar two-point functions for any n behave like free fields of the effective dimension d_{eff}=6 in the infra-red limit.

description: We formulate and prove a new variant of the Segal Conjecture describing the group of homotopy classes of stable maps from the p-completed classifying space of a finite group G to the classifying space of a compact Lie group K as the p-adic completion of the Grothendieck group of finite principal (G,K)-bundles whose isotropy groups are p-groups. Collecting the result for different primes p, we get a new and simple description of the group of homotopy classes of stable maps between (uncompleted) classifying spaces of groups. This description allows us to determine the kernel of the map from the Grothendieck group A(G,K) of finite principal (G,K)-bundles to the group of homotopy classes of stable maps from BG to BK.

description: En este trabajo se estudia la producción textil de El Argar mediante el análisis de las pesas de telar del Complejo Estructural XVIa del yacimiento de Peñalosa (Baños de la Encina, Jaén). Se identificarán el nivel de especialización y el tipo de tejido que pudo ser producido. Asimismo, desde una perspectiva de género, se pondrán en relación la actividad textil y la identidad femenina, con base en los enterramientos argáricos. Este estudio podría ser de ayuda en investigaciones futuras en torno a las actividades textiles realizadas tanto en ese yacimiento como en otros poblados de la Cultura Argárica.
description: This paper studies the textile production of El Argar by analysing the loom weights from the Structural Complex XVIa of the site of Peñalosa (Baños de la Encina, Jaén). The level of specialisation and the type of weaving that could have been produced will be identified. Also, from a gender perspective, we will relate textile activity and female identity, based on the Argaric burials. This study could be of help in future research into the textile activities carried out both at this site and at other settlements of the Argaric Culture.
Asymmetric Intra-household Allocation of Calories in China: Implication for Demographic Bias and the Need for Demographic Targeting

description: This article questions the assumption of symmetric consumption behavior in the conventional analysis of intra-household calorie allocation. It proposes a framework that takes into account asymmetric consumption behavior due to liquidity constraints or loss aversion. Using panel data from China, we find that intra-household calorie allocation responds asymmetrically to expected declines and increases in household food availability, which is qualitatively consistent with the liquidity constraint model. Clarifying such asymmetric responses enables us to relate calorie elasticity estimates to the status of demographic groups within a household without requiring a full interpretation of the ordering of the estimates across demographic groups. Results also show that by ignoring such asymmetric responses, conventional analysis can underestimate demographic differences in calorie elasticity estimates and provide misleading implications about the need for demographic targeting in nutrition programs.

description: We propose a set-up to realize two-channel Kondo physics using quantum dots. We discuss how the charge fluctuations on a small dot can be accessed by using a system of two single electron transistors arranged in parallel. We derive a microscopic Hamiltonian description of the set-up that allows us to make connection with the two-channel Anderson model (of extended use in the context of heavy-Fermion systems) and in turn make detailed predictions for the differential capacitance of the dot. We find that its lineshape, which we determined precisely, shows a robust behavior that should be experimentally verifiable.

description: NbSe2 is a remarkable superconductor in which charge-density order coexists with pairing correlations at low temperatures. Here, we study the interplay of magnetic adatoms and their Yu–Shiba–Rusinov (YSR) bound states with the charge density order. Exploiting the incommensurate nature of the charge-density wave (CDW), our measurements provide a thorough picture of how the CDW affects both the energies and the wave functions of the YSR states. Key features of the dependence of the YSR states on adsorption site relative to the CDW are explained by model calculations. Several properties make NbSe2 a promising substrate for realizing topological nanostructures. Our results will be important in designing such systems.
Spin-1/2 fermionic operators of ${\cal {N}}=4$ SYM theory and DIS from type IIB supergravity

description: We study deep inelastic scattering (DIS) of charged leptons from polarised spin-1/2 hadrons in terms of the gauge/gravity duality. We calculate the structure functions related to spin-1/2 fermionic operators of ${\cal {N}}=4$ SYM theory in the planar limit and at strong coupling. Specifically, we focus on the twist-3 operator which is dual to a certain dilatino mode and gives the leading contribution to the hadronic tensor. We consider the Bjorken variable within the parametric range $λ^{-1/2}_{SYM} \ll x < 1$ where the supergravity dual description holds. From dimensional reduction of type IIB supergravity on the five-sphere, we derive the interaction terms involving two dilatini and a massless vector field mode. This vector field is a linear combination of certain components of the graviton and the four-form potential. The angular integrals on the five-sphere lead to selection rules for the interactions with important consequences on the dynamics. This implies the existence of new terms contributing to the structure functions that we explicitly calculate. The leading contribution comes from the Pauli term, followed by the contributions from the new terms we found.

description: This study deals with the issue of extreme coefficients in geographically weighted regression (GWR) and their effects on mapping coefficients using three datasets with different spatial resolutions. We found that although GWR yields extreme coefficients regardless of the resolution of the dataset or types of kernel function, 1) the GWR tends to generate extreme coefficients for less spatially dense datasets, 2) coefficient maps based on polygon data representing aggregated areal units are more sensitive to extreme coefficients, and 3) coefficient maps using bandwidths generated by a fixed calibration procedure are more vulnerable to the extreme coefficients than adaptive calibration.
On the new LHCb angular analysis of $B \to K^* μ^+ μ^-$: Hadronic effects or New Physics?

description: The new angular analysis of the decay $B \to K^* \ell^+ \ell^-$ recently presented by the LHCb Collaboration still indicates some tensions with the Standard Model predictions. There are several ongoing analyses to solve the problem of separating hadronic and New Physics effects in this decay, but the significance of the observed tensions in the angular observables in $B \to K^* μ^+μ^-$ is still dependent on a theory guesstimate of the hadronic contributions to these decays. Using the new data from LHCb we offer two tests which make a statistical comparison to determine whether the most favoured explanation of the anomalies is New Physics or underestimated hadronic effects. We then analyse the usefulness of these tests in two future scenarios. Finally, we update our global fits to all available $b \to s $ data and discuss the impact of the new LHCb measurements.

description: After great improvements in energy efficiency in the 1970’s, Japan has made little progress in reducing energy consumption since 1990, the base year for the Kyoto Protocol. This study is motivated by the recent growing demands among policy makers to find all possibilities for saving energy. To make informed decisions on how to save energy, policy makers need detailed information on energy consumption structures within each jurisdiction. First, in this article, I decompose national level energy intensity into efficiency and activity effects with the Fisher Ideal index, and then estimate regressions on prefecture level residential electricity demand between 1990 and 2003. It is found that national level energy intensity declined by seventy three percent from 1970 to 2003; sixty three percent of the decline may be attributed to improvement in energy efficiency. Energy intensity, however, has slightly increased since early 1990’s. Secondly, this paper explores the impact of reduction of carbon emission on the economy. I find that the Japanese government needs to enact the environmental taxes on a $12/ton in order to meet the Kyoto Protocol. It is also found that imposing a $12/ton environmental tax reduces Japanese GDP by around six percent and equivalent variations in urban regions fall while equivalent variations in rural regions rise.

Gauge procedure with gauge fields of various ranks

description: The standard procedure for making a global phase symmetry local involves the introduction of a rank 1, vector field in the definition of the covariant derivative. Here it is shown that it is possible to gauge a phase symmetry using fields of various ranks. In contrast to other formulations of higher rank gauge fields we begin with the coupling of the gauge field to some matter field, and then derive the gauge invariant, field strength tensor. Some of these gauge theories are similar to general relativity in that their covariant derivatives involve derivatives of the rank n gauge field rather than just the gauge field. For general relativity the covariant derivative involves the Christoffel symbols which are written in terms of derivatives of the metric tensor. Many (but not all) of the Lagrangians that we find for these higher rank gauge theories lead to nonrenormalizable quantum theories which is also similar to general relativity.

La guerre et la paix dans la poésie épique en France (1500–1800)

description: Les conflits en France entre 1500 et 1800, qui résultent entre autres de bouleversements confessionnels (les guerres de Religion), politiques (la monarchie absolue) ou concernant l'histoire des idées (les Lumières), font naître un vaste panorama de poèmes épiques aux sujets mythiques, historiques, bibliques ou scientifiques. Depuis les premiers essais épiques au temps des guerres d'Italie jusqu'aux Colombiades au XVIIIe siècle, la dimension de la guerre, qui se veut une constante dans la tradition du genre depuis Homère, ainsi que celle de la paix, liée à la vision d'un âge d'or chez Virgile, sont représentées et évaluées de manière variée et polyvalente. Ces variations dépendent du modèle épique choisi, des considérations poétologiques ainsi que de l'arrière-plan socioculturel auquel les poètes appartiennent. Elles concernent tant la représentation de la violence sur les champs de bataille que la conception et la modélisation du héros épique. Au sein d'un genre fortement codifié émergent donc de multiples essais qui conçoivent de nouveaux regards sur la guerre et la paix tout en les intégrant dans le répertoire de la tradition épique.

description: We carry out in full generality and without fixing specific boundary conditions, the symmetry and charge analysis near a generic null surface for two and three dimensional (2d and 3d) gravity theories. In 2d and 3d there are respectively two and three charges which are generic functions over the codimension one null surface. The integrability of charges and their algebra depend on the state-dependence of symmetry generators which is a priori not specified. We establish the existence of infinitely many choices that render the surface charges integrable. We show that there is a choice, the "fundamental basis", where the null boundary symmetry algebra is the Heisenberg+Diff(d-2) algebra. We expect this result to be true for d>3 when there is no Bondi news through the null surface.

description: Increasing grain price volatility over the last year has revived the discussion on optimal marketing strategies. Various models of optimal grain marketing have been proposed and simulated in the literature. In this study an overview on these models is presented and critical aspects are discussed. Optimal strategies are then applied to the wheat market in Germany and Poland. Results indicate that gains from optimal marketing are rather small and uncertain in the real world, indicating that scientific assistance might be of limited importance. However, an understanding of optimization and price generating processes is likely to improve farmers’ decisions, e.g. if farmers have additional (private) information to improve price forecasts.
