description: We examine the phenomenological implications at colliders for the existence of higher-derivative gravity terms as extensions to the Randall-Sundrum model. Such terms are expected to arise on rather general grounds, e.g., from string theory. In 5-d, if we demand that the theory be unitary and ghost free, these new contributions to the bulk action are uniquely of the Gauss-Bonnet form. We demonstrate that the usual expectations for the production cross section and detailed properties of graviton Kaluza-Klein resonances and TeV-scale black holes can be substantially altered by existence of these additional contributions. It is shown that measurements at future colliders will be highly sensitive to the presence of such terms.

description: A gauge theory can be formulated on a noncommutative (NC) spacetime. This NC gauge theory has an equivalent dual description through the so-called Seiberg-Witten (SW) map in terms of an ordinary gauge theory on a commutative spacetime. We show that all NC U(1) instantons of Nekrasov-Schwarz type are mapped to ALE gravitational instantons by the exact SW map and that the NC gauge theory of U(1) instantons is equivalent to the theory of hyper-Kaehler geometries. It implies the remarkable consequence that ALE gravitational instantons can emerge from local condensates of purely NC photons.

description: Since some decades, agri-food products exchanges can be carried on using Information and Communication Technology (ICT) tools. Anyway, their adoption in the agri-food sector appears to be hindered, both because of consolidated dynamics in developing B2B transactions, and of the peculiarities of the agri-food products themselves. The lack of direct relationships between partner heighten problems connected with food safety assessments, and with the definition of standardized production practices able to match business partner’ needs. Standardization is the key point in the relationship between e-commerce and agri-food sector. As for some products it is possible to define standardized requirements, it is hard to find a collocation for the wide range of agri-food differentiated and quality products in e-commerce B2B relationships. Moreover, existing e-marketplaces are not always able to convey properly the degree of differentiation and the peculiarities of agri-food products. The study aims at analyzing the barriers connected with the adoption of e-commerce in B2B relationships in agri-food sector, defining the factors which affect the interaction between the two areas. The attitude towards e-commerce showed by potential ICT tools users, chosen between Italian agri-food operators, has been analyzed; moreover, an overview on the evolution of agri-food e-marketplaces in the last 5 years has been carried on. The results describe the main problems concerning the adoption of e-commerce in agri-food sector, deeply connected with the agri-food products specifics. In spite of positive outcomes about efficiency and transactions for standardized products, the interaction between ICT tools and agri-food sector’s needs becomes problematic in case of high quality levels and differentiation, which can’t be properly conveyed by e-marketplaces. Results also highlight the role of trust and reputation in e-environments.

description: The inverse quantum scattering problem for the perturbed Bessel equation is considered. A direct and practical method for solving the problem is proposed. It allows one to reduce the inverse problem to a system of linear algebraic equations, and the potential is recovered from the first component of the solution vector of the system. The approach is based on a special form Fourier-Jacobi series representation for the transmutation operator kernel and the Gelfand-Levitan equation which serves for obtaining the system of linear algebraic equations. The convergence and stability of the method are proved as well as the existence and uniqueness of the solution of the truncated system. Numerical realization of the method is discussed. Results of numerical tests are provided revealing a remarkable accuracy and stability of the method.

The Laurent series up to ${\cal O}(\ep^2)$ is needed as input to that part of the NNLO corrections to heavy flavor production at hadron colliders where the one-loop integrals appear in the loop-by-loop contributions. The four-point integrals are the most complicated. The ${\cal O}(\ep^2)$ expansion of the three- and four-point integrals contains in general polylogarithms up to ${\rm Li}_4$ and functions related to multiple polylogarithms of maximal weight and depth four.

description: We focus on a simple framework on wheat producer behaviour in a context of price output uncertainty. More precisely, we establish a relationship between ex post output price level and allocative inefficiency that allows to characterize farmers’ risk preferences. Given this analysis, the connection between risk aversion and other socioeconomic variables (such as degree of output specialisation, total asset, debts, farmer’s age…) can furthermore empirically be explored. This relationship is empirically tested on an unbalanced panel including about 650 wheat producers located in the French Department of Meuse over 1992- 2003.
Creating cosmopolis : the end of mainstream
Creators: name: Dang, Steven R.
Publisher: name: University of British Columbia
Year: 2009

description: Increasing cultural globalisation and the assertion of cultural identities present an interesting opportunity for cities in the postmodern Western World. An increasingly multi-situated polity must better reflect and serve an increasingly self-aware and heterogeneous population in search of better planning, community and social justice. A great deal of research in diversity issues has been conducted in various disciplines, but there is little integration of this theory and even less instruction as to its application. This thesis attempts to address the deficiencies - providing some rationale and some guidance towards the diversification of civic culture as a model of incorporation. Diversification requires a significant shift in our understanding of culture, identity, community and self - an end to mainstream and its hegemony. It places the onus for change on local institutions and operates on an assumption of difference, a desire for meaningful incorporation and a commitment to equality as equity. These principles translate into the pursuit of increasingly differentiated benefits, inclusive participation, varied discourse and inclusive definitions. For the transformation to be truly meaningful and systemic, it must take place in all agencies of civic culture: government, civil society, business, the media and family. A conceptual, prescriptive and evaluative framework for cultural diversification is thus elaborated. Change will require deliberate purpose and action. This thesis attempts to provide some direction by applying the discussion to a level at which most urban leaders, planners and cultural producers work. A local organisation in Vancouver, Canada - a reputed leader in diversity - is selected as a case to illustrate application of the developed framework and to enrich it with an initial investigation of how practitioners work towards the diversification of their individual institutions and their larger socio-cultural environment. It is hoped that strategies learned here, and in future applications of this research, can provide guidance for other organisations and that numerous small efforts will be rewarded with the gradual transformation of the whole.
Generalized On-Shell Ward Identities in String Theory

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It is demonstrated that an infinite set of string-tree level on-shell Ward identities, which are valid to all sigma-model loop orders, can be systematically constructed without referring to the string field theory. As examples, bosonic massive scattering amplitudes are calculated explicitly up to the second massive excited states. Ward identities satisfied by these amplitudees are derived by using zero-norm states in the spetrum. In particular, the inter-particle Ward identity generated by the D2xD2' zero-norm state at the second massive level is demonstrated. The four physical propagating states of this mass level are then shown to form a large gauge multiplet. This result justifies our previous consideration on higher inter-spin symmetry from the generalized worldsheet sigma-model point of view.

description: An NEIO approach is used to measure seller market power in the French Comté cheese market, characterised by government-approved supply control. The estimation is performed on quarterly data at the wholesale stage over the period 1985-2005. Three different elasticity shifters are included in the demand specification, and the supply equation accounts for the existence of the European dairy quota policy. The market power estimate is small and statistically insignificant. Monopoly is rejected, as well as weak forms of Cournot oligopoly. Results appear to be robust to the choice of functional form, and suggest little effect of the supply control scheme on consumer prices.

description: We prove that the focal set generated by the reflection of a point source off a translation invariant surface consists of two sets: a curve and a surface. The focal curve lies in the plane orthogonal to the symmetry direction containing the source, while the focal surface is translation invariant. This is done by constructing explicitly the focal set of the reflected line congruence (2-parameter family of oriented lines in ${\Bbb{R}}^3$) with the aid of the natural complex structure on the space of all oriented affine lines.
Accelerated black holes in an anti-de Sitter universe

description: The C-metric is one of few known exact solutions of Einstein's field equations which describes the gravitational field of moving sources. For a vanishing or positive cosmological constant, the C-metric represents two accelerated black holes in asymptotically flat or de Sitter spacetime. For a negative cosmological constant the structure of the spacetime is more complicated. Depending on the value of the acceleration, it can represent one black hole or a sequence of pairs of accelerated black holes in the spacetime with an anti-de Sitter-like infinity. The global structure of this spacetime is analyzed and compared with an empty anti-de Sitter universe. It is illustrated by 3D conformal-like diagrams.

Inner crust of a neutron star at crystallization in a multi-component approach

description: The possible presence of amorphous and heterogeneous phases in the inner crust of a neutron star is expected to reduce the electrical conductivity of the crust, with potentially important consequences on the magneto-thermal evolution of the star. In cooling simulations, the disorder is quantified by an impurity parameter which is often taken as a free parameter. We aim to give a quantitative prediction of the impurity parameter as a function of the density in the crust,performing microscopic calculations including up-to-date microphysics of the crust. A multi-component approach is developed at finite temperature using a compressible liquid drop description of the ions with an improved energy functional based on recent microscopic nuclear models and optimized on extended Thomas-Fermi calculations. Thermodynamic consistency is ensured by adding a rearrangement term and deviations from the linear mixing rule are included in the liquid phase. The impurity parameter is consistently calculated at the crystallization temperature as determined in the one-component plasma approximation for the different functionals. Our calculations show that at the crystallization temperature the composition of the inner crust is dominated by nuclei with charge number around $Z \approx 40$, while the range of the $Z$ distribution varies from about 20 near the neutron drip to about 40 closer to the crust-core transition. This reflects on the behavior of the impurity parameter that monotonically increases with density up to around 40 in the deeper regions of the inner crust. Our study shows that the contribution of impurities is non-negligible, thus potentially having an impact on the transport properties in the neutron-star crust. The obtained values of the impurity parameter represent a lower limit; larger values are expected in the presence of non-spherical geometries and/or fast cooling dynamics.

description: This study examines the supply response of the Greek beef market and the possible effect of the European Union’s Common Agricultural Policy (CAP) on the Greek beef sector during the period 1993-2005. A GARCH process is used to estimate expected price and price volatility while several different symmetric, asymmetric and nonlinear GARCH models are estimated. The empirical results show that price volatility and feed price are important risk factors of the supply repose function, while the negative asymmetric price volatility which was detected implies that producers have a weak market position. Furthermore, the empirical findings confirm that the annual premium paid by EU to beef producers had a positive impact on the production level and that the change of the EU price support regime after 2006 will have negative effects on the beef production level in Greece.

description: Using finite-temperature diagonalization we investigate the optical conductivity $σ(ω)$ and spin-orbital dynamics in the CE phase of half-doped manganites. We find $σ(ω)$ characterized by a broad spectrum with pronounced optical gap due to charge ordering induced by Coulomb and further neighbor Jahn-Teller interactions. With increasing temperature the conductivity shows a significant change over a wide energy range with a characteristic shift towards lower frequencies. In the low temperature CE phase we observe in-gap absorption due to combined orbiton-spin excitations.

Group Processing: Students Reflections on the Experience and Impact of Group Processing

Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2021

description: Problem-based or Enquiry-based learning is recognized as a transformative pedagogy, but there is a paucity of research examining group processing, a critical component of this pedagogy. Group processing is a structured approach to peer- and self-assessment that encourages learning that is both self-reflective and collaborative. Students develop the skills of peer and self-assessment, they learn to receive and deliver constructive feedback, and they benefit from continuous assessment. This article presents a mixed method study that asked former students, who had taken an enquiry-based learning seminar within the past 10 years, to reflect on their experience of group processing. Participants concluded that, based on their own experience, group processing is a skill transferable to other contexts and had a significant effect on their university experience.

description: Nowadays, power system inertia is changing as a consequence of replacing conventional units by renewable energy sources, mainly wind and PV power plants. This fact affects significantly the grid frequency response under power imbalances. As a result, new frequency control strategies for renewable plants are being developed to emulate the behaviour of conventional power plants under such contingencies. These approaches are usually called 'virtual inertia emulation techniques'. In this paper, an analysis of power system inertia estimation from frequency excursions is carried out by considering different inertia estimation methodologies, discussing the applicability and coherence of these methodologies under the new supply-side circumstances. The modelled power system involves conventional units and wind power plants, including wind frequency control strategies in line with current mix generation scenarios. Results show that all methodologies considered provide an accurate result to estimate the equivalent inertia based on rotational generation units directly connected to the grid. However, significant discrepancies are found when frequency control strategies are included in wind power plants decoupled from the grid. In this way, authors consider that it is necessary to define alternative inertia estimation methodologies by including virtual inertia emulation. Extensive discussion and results are also provided in this study.

Evaluating Different Growth Scenarios for Organic Farming Using Bayesian Techniques

description: Different views exist on the future development of organic agriculture. The Dutch government believes that in 2010 10% of the farm land will be used for organic farming. Others have a more radical view: due to increasing emphasis on sustainable production in the end all farming will be organic. Others believe in a more pessimistic scenario in which the recent growth in organic was just a temporary upswing and that the share of organic farmers already reached its maximum. In this paper different potential scenarios for the further growth of organic farming are evaluated using Bayesian techniques. A nonlinear logistic growth model explaining the share of organic farms is estimated using available historical data for Dutch agriculture. Various scenarios imply different prior values for the parameters. Because of the non-linear model specification a Metropolis-Hastings algorithm is used to simulate the posterior densities of the model parameters. Finally, using Bayesian model comparison techniques probabilities can be attached to the different scenarios. The proposed methodology is a promising tool for analysing technology diffusion in general when different scenarios for diffusion are possible and limited data is available.
Orbital magnetic field effects in spin liquid with spinon Fermi sea: Possible application to $κ$-(ET)$_2$Cu$_2$(CN)$_3$

description: We consider orbital magnetic field effects in a spin liquid phase of a half-filled triangular lattice Hubbard system close to the Mott transition, continuing an earlier exploration of a state with spinon Fermi surface. Starting from the Hubbard model and focusing on the insulator side, we derive an effective spin Hamiltonian up to four-spin exchanges in the presence of magnetic field, and find that the magnetic field couples linearly to spin chirality on the triangles. The latter corresponds to a flux of an internal gauge field in a gauge theory description of the spin liquid, and therefore a static such internal flux is induced. A quantitative estimate of the effect is obtained using a spinon mean field analysis, where we find that this orbital field seen by the spinons is comparable to or even larger than the applied field. We further argue that because the stiffness of the emergent internal gauge field is very small, such a spinon-gauge system is strongly susceptible at low temperatures to an instability of the homogeneous state due to strong Landau level quantization for spinons. This instability is reminiscent of the so-called strong magnetic interaction regime in metals with the usual electromagnetic field, but we estimate that the corresponding temperature--magnetic field range is significantly broader in the spinon-gauge system.

The effects of liberalization are bound to depend on the path of agricultural policies in Turkey and in the EU during the accession negotiations. In order to evaluate the possible impacts of a variety of policy alternatives and scenarios, an economic modelling approach based on non-linear mathematical programming is appropriate. In this framework, the major purpose of this paper is to evaluate the impact of Turkish integration to the EU on agriculture using an agricultural sector model for Turkey. The basic approach undertaken supplements the past efforts by incorporating Maximum Entropy to the positive mathematical programming, together with updated base period and including recent policy changes. Following the integration with EU, the net exports in agro-food products decline mainly due to the expansion of trade in livestock products. Overall welfare effects of including agrofood products in the customs union and membership are small. Consumers benefit from declining prices. CAP supports are determinative for producers’ welfare. The results of the simulations provide also updated estimates about the possible size of CAP expenditures for Turkish agriculture.

description: Land-use in rural areas may be reallocated between farmland and forest and nature areas. This paper addresses reasons for forest and landed estate owners to own their property and motivations for different activities of forest and real estate owners, including leasing out land to farmers. In 2006 we carried a survey among 171 forest and landed estates owners in the Eastern part of the Netherlands (response rate of 44%). Preserving family property, preserving nature and landscape, and hobby or spending free time are ranked as important reasons for having a forestry enterprise or a landed estate. Most of the owners can be characterised as multifunctional. They often fulfil a combination of wood production, preservation of nature and landscape, providing facilities for tourism and hunting, leasing out of land and agriculture. Based on results of regression analysis we can conclude that not every forest and landed estate owner prefers multifunctionality in a similar way. Leasing out land to farmers is one of activities where income is an important reason.
A General Automatic Method for Optimal Construction of Matrix Product Operators Using Bipartite Graph Theory

description: Constructing matrix product operators (MPO) is at the core of the modern density matrix renormalization group (DMRG) and its time dependent formulation. For DMRG to be conveniently used in different problems described by different Hamiltonians, in this work we propose a new generic algorithm to construct the MPO of an arbitrary operator with a sum-of-products form based on the bipartite graph theory. We show that the method has the following advantages: (i) It is automatic in that only the definition of the operator is required; (ii) It is symbolic thus free of any numerical error; (iii) The complementary operator technique can be fully employed so that the resulting MPO is globally optimal for any given order of degrees of freedom; (iv) The symmetry of the system could be fully employed to reduce the dimension of MPO. To demonstrate the effectiveness of the new algorithm, the MPOs of Hamiltonians ranging from the prototypical spin-boson model and Holstein model to the more complicated ab initio electronic Hamiltonian and the anharmonic vibrational Hamiltonian with sextic force field are constructed. It is found that for the former three cases, our automatic algorithm can reproduce exactly the same MPOs as the optimally hand-crafted ones already known in the literature.

Economic Partnership Agreements and WTO negotiations. A quantitative assessment of trade preference granting and erosion in the banana market

description: The paper provides a quantitative assessment of the impact on the banana market of the expansion of trade preferences the EU granted ACP countries with the recent Economic Partnership Agreements (EPA) and of the possible erosion of these preferences as a result of different possible endings, if any, of on-going WTO negotiations. The results of the simulations performed suggest that the impact of the EPA on the production and consumption of bananas in the EU will be limited, while benefits for ACP countries will be significant (at the expense of MFN exporters). However, a final agreement in the WTO DDA round may bring an erosion of the preferential margins currently enjoyed by ACP countries of such an order of magnitude as to cancel out most of these benefits. The actual outcome will depend on the EU bound tariff for bananas which will be subject to the reduction commitments (will this be the one indicated in the Uruguay Round EU “schedules”, or the tariff introduced with the reform of the EU import regime for bananas in 2006?); on whether bananas will be included among “tropical products”; and, if this is the case, on the provisions for “tropical products” contained in the final agreement. Possible outcomes of current bilateral negotiations between the EU and MFN exporters are analyzed as well.

description: We study numerically the nonequilibrium dynamics of the three-dimensional Heisenberg Edwards-Anderson spin glass submitted to protocols during which temperature is shifted or cycled within the spin glass phase. We show that (partial) rejuvenation and (perfect) memory effects can be numerically observed and study both effects in detail. We quantitatively characterize their dependences on parameters such as the amplitude of the temperature changes, the timescale at which the changes are performed, and the cooling rates used to vary the temperature. We contrast our results both to those found numerically in the Ising version of the model, and to experimental results in different samples. We discuss the theoretical interpretations of our findings, arguing, in particular, that `full' rejuvenation can be observed in experiments even if temperature chaos is absent.

Explaining German imports of olive oil: evidence from a gravity model

description: In this study the case of olive oil imports of Germany is examined since olive oil is a traditional Mediterranean commodity and Germany is the biggest importer in the EU. A gravity model has been employed so as to analyse those factors that explain the German imports of olive oil that were identified in a preceding analysis of the German olive oil supply chain. The results of two random-effects models corrected for serial correlation and heteroskedasticity suggest that being a Mediterranean Partner country of the EU has the highest impact on trade flows to Germany, thus supporting further Euromediterranean trade integration. The level of trade to Germany is positively related to existence of direct marketing channels and to tourism implying that these factors should be explored more in the future by the Mediterranean countries so as to boost their exports.
Analytic marginalization of $N(z)$ uncertainties in tomographic galaxy surveys

description: We present a new method to marginalize over uncertainties in redshift distributions, $N(z)$, within tomographic cosmological analyses applicable to current and upcoming photometric galaxy surveys. We allow for arbitrary deviations from the best-guess $N(z)$ governed by a general covariance matrix describing the uncertainty in our knowledge of redshift distributions. In principle, this is marginalization over hundreds or thousands of new parameters describing potential deviations as a function of redshift and tomographic bin. However, by linearly expanding the theory predictions around a fiducial model, this marginalization can be performed analytically, resulting in a modified data covariance matrix that effectively downweights the modes of the data vector that are more sensitive to redshift distribution variations. We showcase this method by applying it to the galaxy clustering measurements from the Hyper Suprime-Cam first data release. We illustrate how to marginalize over sample-variance of the calibration sample and a large general systematic uncertainty in photometric estimation methods, and explore the impact of priors imposing smoothness in the redshift distributions.
