description: We take advantage of the Hubble Ultra Deep Field (UDF) data to study the restframe optical and ultra violet (UV) morphologies of the novel population of Distant Red Galaxies (DRGs). Six galaxies with J-Ks > 2.3 are found to Ks=21.5, five of which have photometric redshifts z_phot > 2, corresponding to a surface density of 0.9/arcmin^2. The surface brightness distributions of the z_phot > 2 galaxies are better represented by exponential disks than R^{1/4}-laws. Two of the z_phot > 2 galaxies are extended, while three have compact morphologies. The restframe optical morphology of the z_phot > 2 galaxies is quite different from the restframe UV morphology: all the galaxies have red central components which dominate in the NICMOS H_{160}-band images, and distinct off-center blue features which show up in (and often dominate) the ACS images. The mean measured effective radius of the z_phot > 2 galaxies is =1.9+/-1.4 kpc, similar (within the errors) to the mean size of LBGs at similar redshifts. All the DRGs are resolved in the ACS images, while four are resolved in the NICMOS images. Two of the z_phot > 2 galaxies are bright X-ray sources and hence host AGN. The diverse restframe optical and UV morphological properties of DRGs derived here suggest that they have complex stellar populations, consisting of both evolved populations that dominate the mass and the restframe optical light, and younger populations, which show up as patches of star formation in the restframe UV light; in many ways resembling the properties of normal local galaxies. This interpretation is supported by fits to the broadband SEDs, which for all five z_phot > 2 are best represented by models with extended star formation histories and substantial amounts of dust.

description: Promouvoir le développement économique et social d'un territoire commence par la reconnaissance de la vocation intime du territoire même. La vocation de la Province de Parme est sans doute orientée vers le secteur agroalimentaire. L'impact de l'agro-alimentaire, lié aux produits locaux, sur le domaine socio-économique en question, est essentiel, non seulement pour la valeur de la production industrielle et l'attraction de nouveaux investissements, mais aussi pour la relance du tourisme dans la région. Avec la redécouverte de la culture « locale » par les consommateurs, le rôle des produits typiques est devenu de plus en plus considérable par l'importance accordée à l’association « produit typique – terroir » et « produit typique - processus de production locale ». Le « cercle vertueux » qui peut être activé prévoit la mise en oeuvre d’actions pour souligner les relations entre les productions typiques et les autres composantes du terroir afin de fournir tous les biens et services demandés par les consommateurs, y compris le paysage, la culture, l’environnement, les traditions et l’image globale du territoire. Les initiatives liées au tourisme enogastronomique sont en accord avec ce contexte. Les « Musei del Cibo» (Musées du Gout) font partie d’un réseau muséal déplacé sur le territoire, situé dans la province de Parme, dédié aux produits typiques et locaux où la collection en représente l’histoire des produits et les traditions qui les ont accompagnées. Ils sont, en effet, une initiative qui développe les relations entre produit typique, ou local, et les autres composantes du territoire, rendant visible, au même temps, ces rapports à l'extérieur.

description: In this paper, we analyze the structural change in the supply chain of oil palm in North Sumatra, Indonesia, especially after the financial crisis of the late 20th century. We first describe the past and present market structure and conduct of oil palm industries in North Sumatra with an industrial organization approach based on our field study. The analysis reveals that the supply chain of oil palm in North Sumatra has changed such that farmers had more power to determine FFB prices over crushing companies, especially from 2001 through 2004. However, farmers lost bargaining power during 2007-2008 due to a decrease in palm oil demand, plunging of palm oil prices, and a regulation imposed upon crushing companies by the Ministry of Agriculture. To analyze such structural changes empirically, we test the existence of Asymmetric Price Transmission (APT), in which the speed of adjustments of the output price after the input price increases or decreases is different; the existence of APT implies the existence of market power. We apply the (Momentum) Threshold Autoregressive ((M-)TAR) model to estimate APT. According to the estimation results, crushing companies had more power to determine FFB prices over farmers until around March 2002. This situation changed such that farmers had more bargaining power from around April 2002 to around April 2007 before the power became balanced. The structural change test also shows these time points as optimal structural change points. The APT estimation, however, has little rigorous theoretical background, and the concept of APT is not necessarily related to market power. Hence, we next analyze the market power of crushers and farmers both theoretically and empirically. The estimation result of market power indicates that the farmers had no market power before the third quarter of 2002, but they did have market power from the next quarter to the first quarter of 2008, after which time they again lose market power. These empirical results are consistent both with each other and with the descriptions of the structural change. Finally, we conclude and draw some implications for farmers, crushers, and consumers of palm oil.

Dynamic Localization in Quantum Wires

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: In the paper the dynamic localization of charged particle (electron) in a quantum wire under the external non-uniform time-dependent electric field is considered. The electrons are trapped in a deep 'dynamic' quantum wells which are the result of specific features of the potential imposed on 2D electron gas: the scale of spatial nonuniformity is much smaller then the electron mean free path (L_1 << \bar{l}) and the frequency is much greater then τ^{-1}, where τis the electron free flight time. As a result, the effect of this field on the charged particle is in a sense equivalent to the effect of a time-independent effective potential, that is a sequence of deep 'dynamic' quantum wells were the elelctrons are confined. The possible consequeces of this effect are also discussed and similarity with the classical Paul traps are emphasized.

description: The parameters of a quantum system grow exponentially with the number of involved quantum particles. Hence, the associated memory requirement goes well beyond the limit of best classic computers for quantum systems composed of a few dozen particles leading to huge challenges in their numerical simulation. This implied that verification, let alone, design of new quantum devices and experiments, is fundamentally limited to small system size. It is not clear how the full potential of large quantum systems can be exploited. Here, we present the concept of quantum computer designed quantum hardware and apply it to the field of quantum optics. Specifically, we map complex experimental hardware for high-dimensional, many-body entangled photons into a gate-based quantum circuit. We show explicitly how digital quantum simulation of Boson Sampling experiments can be realized. Then we illustrate how to design quantum-optical setups for complex entangled photon systems, such as high-dimensional Greenberger-Horne-Zeilinger states and their derivatives. Since photonic hardware is already on the edge of quantum supremacy (the limit beyond which systems can no longer be calculated classically) and the development of gate-based quantum computers is rapidly advancing, our approach promises to be an useful tool for the future of quantum device design.

description: We describe searches for B meson decays to the charmless vector-vector final states omega K* and omega rho in 89 million B-Bbar pairs produced in e+e- annihilation at sqrt(s)=10.58 GeV. We measure the following branching fractions in units of 10^{-6}: BF(B0 -> omega K*0) = 3.4 +1.8 -1.6 +/- 0.4 (<6.0), BF(B+ -> omega K*+) = 3.5 +2.5 -2.0 +/- 0.7 (<7.4), BF(B0 -> omega rho0) = 0.6 +1.3 -1.1 +/- 0.4 (<3.3), and BF(B+ -> omega rho+) = 12.6 +3.7 -3.3 +/- 1.6. The first error quoted is statistical, the second systematic, and the upper limits are defined at 90% confidence level. For B+ -> omega rho+ we also measure the longitudinal spin alignment fraction f_L = 0.88 +0.12 -0.15 +/- 0.03 and charge asymmetry Ach = (5 +/- 26 +/- 2)%.

In my backyard : stories of identity, community, and curriculum through creative writing

description: The thesis, In my Backyard: Stories of Identity, Community, and Curriculum through Creative Writing, is a collection of three narratives of finding voice and community through creative writing and using these discoveries to shape a vision for writing in the classroom. Themes that emerged through this personal and pedagogical research included: the dichotomy between in and out of school writing, writing as an exploration of identity, and the ability of a classroom writing community to promote reflection and risk-taking. The thesis is written in three parts. The three parts in summary are an archive of my learning, a record of student voices on creativity and writing, and a practical teaching and learning tool for teachers of creative writing. Each part of the thesis vividly paints the landscape it represents and captures the characters who play with words in each context. Part One is an exploration and an archive of my matrilineal roots and what I learn from the writing on the dog-eared index cards in my grandmother's recipe box. I am transported back to a time when wives and mothers cooked dinner and desserts, like my grandmother's lemon squares, and kitchens were places of female wisdom. Parts Two and Three tell the story of students learning about their identities through creative writing. This research included personal observation, the experience of co-teaching, student interviews and student surveys. I learned that our classrooms are important places for creative writing as self expression can build self esteem. This can ultimately lead to a sense of community and personal freedom for young writers. Part Four is a curriculum for a new course, Creative Writing 10, inspired by Atwell's writing workshop approach (1998; 2002). Students look at English through the lens of writer and learn to play with words in the context of a cooperative teacher and student writing community. Together, as students and teachers, we hone the craft of creative writing; the stories in our bones becoming the curriculum from which we learn about who we are and the world we live in.

description: Deep Neural Networks (DNNs) are very popular because of their high performance in various cognitive tasks in Machine Learning (ML). Recent advancements in DNNs have brought beyond human accuracy in many tasks, but at the cost of high computational complexity. To enable efficient execution of DNN inference, more and more research works, therefore, exploit the inherent error resilience of DNNs and employ Approximate Computing (AC) principles to address the elevated energy demands of DNN accelerators. This article provides a comprehensive survey and analysis of hardware approximation techniques for DNN accelerators. First, we analyze the state of the art and by identifying approximation families, we cluster the respective works with respect to the approximation type. Next, we analyze the complexity of the performed evaluations (with respect to the dataset and DNN size) to assess the efficiency, the potential, and limitations of approximate DNN accelerators. Moreover, a broad discussion is provided, regarding error metrics that are more suitable for designing approximate units for DNN accelerators as well as accuracy recovery approaches that are tailored to DNN inference. Finally, we present how Approximate Computing for DNN accelerators can go beyond energy efficiency and address reliability and security issues, as well.

description: The metallic ground state in two-dimensional (2D) superconductors has attracted much attention but is still under intense scrutiny. Especially, the measurements in ultralow temperature region are challenging for 2D superconductors due to the sensitivity to external perturbations. In this work, the resistance saturation induced by external noise, named as "extrinsic anomalous metallic state", is observed in 2D transition metal dichalcogenide (TMD) superconductor 4Ha-TaSe2 nanodevices. However, with further decreasing temperature, credible evidence of intrinsic anomalous metallic state is obtained by adequately filtering external radiation. Our work indicates that at ultralow temperatures the anomalous metallic state can be experimentally revealed as the quantum ground state in 2D crystalline TMD superconductors. Besides, Ising superconductivity revealed by ultrahigh in-plane critical field (Bc2//) going beyond the Pauli paramagnetic limit (Bp) is detected in 4Ha-TaSe2, from one-unit-cell device to bulk situation, which might be due to the weak coupling between the TaSe2 sub-monolayers.

description: This paper focused on how and what diversified activities influence the price level of agritourism. A hypothesis that contrasts two directions was examined: facility-based and local culture-based activities. First, from the conceptual consideration, we defined that agritourism based on local cultural resources can internalize positive externalities, which are accompanied by local cultural resources, into income, unlike facility-based activity that has no connection with local cultural resources. Second, the results of estimations from the price determinant ordered logit model clarified that owning a swimming pool was the most common and influential factor in enhancing the price level while regional diversity was observed in terms of local cultural resource-based activities such as restaurants, world heritage sites and DOC wines. These findings indicate that hardware-based evolution is more effective in the short term than evolution based on software aspects. Nevertheless, this hardware-based evolution of agritourism is implicitly based on the assumption of continuously growing demand and sufficient financial capability for the fixed investment. When growth in demand becomes stagnant, facility installation can be a heavy burden on operators. Consequently, for the sustainable development of agritourism it will be necessary to harness locality to create a balance between facility-based services and local culture-based services.

description: En México desde la década de los noventas, el turismo se ha diversificado, presentando diversas modalidades, siendo el agroturismo una de las de mayor crecimiento, ya que en la se implementan programas para recibir a los visitantes que acuden a estos lugares, los cuales están integrados por múltiples manifestaciones tangibles e intangibles que son testimonio fehaciente de las comunidades rurales. En este sentido las haciendas son espacios estrechamente ligados a la vida de los campesinos, ya que en muchos casos la existencia de ellas marcó sustancialmente la vida familiar de pueblos enteros, la forma de organizarse, las costumbres y tradiciones, la economía, entre otros aspectos. Es decir, las haciendas en México eran algo más que un conjunto de construcciones y una gran extensión de tierra: era una forma de vida. En la presente investigación se realiza el análisis del potencial del patrimonio cultural arraigado en los espacios territoriales relacionados con las haciendas del municipio de Aculco de Espinoza para desarrollar actividades de agroturismo.

description: Collective action cannot develop without the commitment of partners to a common project. Building a new Geographical Indication (GI) implies crucial strategic decisions regarding the norms of the production process, the limits of the geographical area and the choice of the protected GI name. Who is going to make these decisions? What is the best path to kick-off with success the initiative? Two approaches have recently been tested in practice: the cluster approach and the working group approach. This paper presents the scientific background of these two approaches. A state of the art is proposed on the concept of cluster, developed in Industrial Economics. The translation theory, developed in Economic Sociology, is mobilised to analyse the “translation cycles” followed by most working groups. Based on case studies, this paper highlights and explains the benefits and risks of both approaches. It proposes an approach that combines face to face negotiations between the facilitator and potential partners, large information campaigns, and a representative working group in order to guarantee access to information to all and avoid further oppositions.

RURAL POPULATION GROWTH, AGRICULTURAL CHANGE AND NATURAL RESOURCE MANAGEMENT IN DEVELOPING COUNTRIES: A REVIEW OF HYPOTHESES AND SOME EVIDENCE FROM HONDURAS

description: This paper reviews hypotheses about the impacts of rural population growth on agriculture and natural resource management in developing countries and the implications for productivity, poverty, and natural resource conditions. Impacts on household and collective decisions are considered, and it is argued that population growth is more likely to have negative impacts when there is no collective responses than when population growth induces infrastructure development, collective action, institutional or organizational development. The impacts of population pressure, particularly on natural resource conditions, may be very different in different contexts, depending on the nature of local markets, institutions, and other factors. Thus careful and comparative empirical work is needed in different contexts before general conclusions can be drawn. There is still a lack of such empirical evidence. The results of one study in central Honduras are used to examine some of the hypotheses presented. The results support neo-Malthusian concerns about the effects of population growth on land degradation, but also provide some support to Boserupian predictions that population pressure will induce adoption of labor-intensive land improvements, collective action to manage natural resources, and organizational development. In general, however, the impacts of population pressure were found to be relatively small and other factors, including infrastructure development and technical assistance programs, had stronger impacts on agricultural change and natural resource management. Although induced innovation theory argues that population pressure may induce such policy responses, we found that these interventions were more likely in less-densely populated communities. This emphasizes that such “induced” policy responses to population pressure do not happen automatically.

description: Very little is known about changes in the demand characteristics of food in New Zealand. As far as we can determine, there has never been a complete disaggregated food demand model estimated for New Zealand. The object of this paper is to update these estimates using more recent data to see whether there are grounds for believing that the structural changes that occurred primarily during the last two decades are having effects on the magnitude of food demand elasticities in New Zealand. To this end, a Rotterdam food demand system is estimated using time series data. The results indicate that over the last 20 years, household consumption has increased for fruit and vegetables, poultry, food eaten away from home, and sweet products, drinks and other foods. Fish, poultry, meat, farm products, cereals and meals away from home are all more price elastic than earlier estimates.
Bargaining for something better : the Polish peasants and the European Union
Creators: name: Pielacha, Stanislawa Ewa
Publisher: name: University of British Columbia

description: This study investigates and analyzes Polish peasants' attitudes and rationales for opposition to Poland's inclusion in the European Union. It was designed to determine peasant objections, attitudes among peasant landowners and the likelihood of continued their opposition after the impact of EU accession. Face to face interviews were conducted with three strata of Polish peasants who were selected based on their level of landholdings: large, middle and small size. In addition, political leaders and experts were interviewed for their opinions. Pertinent documents (scholarly literature, statistical data, newspapers, Polish state and EU documents, archival materials of political organizations) were researched to provide additional data concerning the peasants' situation, their actions and protests and in order to make the picture of the peasants' circumstances more comprehensive. Since objections pertained to EU accession and the anticipated impact of EU membership on peasants the study also examines EU policies and their previous effect on agriculture as well as future programs that will have a specific impact on Polish peasants. The study concludes that most peasants participated in the anti-European integration movement in order to bargain for better conditions of EU membership. The policies of European integration and the most recent conditions of Poland's membership in the EU discriminate against Polish agriculture vis-a-vis Western European members and favor peasant larger landholdings in Poland over the smaller ones. By the time the differential treatment of Polish agriculture is due to end in 2014, small peasant landholdings will be extinguished. This is likely to displace over one million of peasant households from this occupation. Dependent on state and EU social policies, the restructured peasant class is likely to be characterized by uneducated electorate and by lack of leaders and material resources to engage in the opposition movement against EU policies.

description: This work extends the input-output approach to the study of wall-bounded shear flows manipulated using actuators common in experimental flow control studies. In particular, we adapt this powerful analytical framework to investigate the flow response to specified geometric actuation patterns (e.g., different plasma actuators) that can be applied over a range of different temporal input signals. For example, the commonly studied steady-state (time-averaged) flow response corresponds to a superposition of step responses in our modeling framework. The approach takes advantage of the linearity of the transfer function representation to construct the actuated flow field as a weighted superposition of the flow responses to point sources of varying intensity comprising the actuation model. We first validate the proposed method through comparisons with numerical and experimental studies of the time-averaged behavior of a transitional boundary layer actuated using a dielectric-barrier discharge plasma actuator operating in constricted discharge mode. The method is shown to reproduce the streamwise velocity field and the vortical structures observed downstream from the tested plasma actuator configurations. We then demonstrate that the method provides even better agreement with the steady-state response of the boundary layer subject to actuation from arrays of symmetric plasma actuators arranged in both spanwise and serpentine geometries. These results indicate the utility of this extension to the widely used input-output framework in analyzing the effects of certain actuation modalities that have shown promise in flow manipulation strategies for drag reduction. An important benefit of this analytical method is the low computational cost associated with its use in extensive parametric studies that would be cost-prohibitive using experiments or high-fidelity simulations.

description: For pomerons described by a sum of two simple-pole terms, a soft and a hard pomeron, the unitarity bounds from saturation in impact-parameter space are examined. We consider the effect of these bounds on observables linked with polarisation, such as the analyzing power in elastic proton-proton scattering, for LHC energies. We obtain the s and t dependence of the Coulomb-nuclear interference at small momentum transfer, and show that the effect of the hard pomeron may be observed at the LHC.

Subjects: Marine Biology

description: The fairy basslet (Anthias anthias) is a fis, with a gregary behaviour, that is found commonly at depths from 30m to 200malong the continental shelf and in caves with coralline seabed. Fifty Anthias specimens were collected by scuba divers and transferred to the Argentario Aquarium (Italy), where a special tank was prepared to host them. The anthias spent 3 days in an acclimation containerat different depths before returning to the surface. The present paper disusses the data concerning the first 24 months of their husbandry under natural conditions.

description: In a climate of rapid technological change, it is important to evaluate policies on the innovation incentives that result from the introduction of intellectual property rights as they relate to agricultural genetic resources. In this paper, we use a stylized model of cumulative innovation to explore the dynamics of introducing patent protection with licensing agreements, and then we contrast those results with the comparative-statics viewpoint. We also investigate the dynamic effects of claims on behalf of farmers on the profits of private crop breeders whose output is newly protected by patents. We show that the choices about patent life and licensing share that optimize worldwide dynamic social welfare can be quite different from the values that maximize steady-state social welfare. Further, recognition of farmers’ rights entails a dynamic welfare loss to producers and consumers that is not revealed in a comparative-statics analysis.

description: Three slow glitches in the rotation rate of the pulsar B1822-09 were revealed over the 1995-2004 interval. The slow glitches observed are characterized by a gradual increase in the rotation frequency with a long timescale of several months, accompanied by a rapid decrease in the magnitude of the frequency first derivative by 1-2 per cent of the initial value and subsequent exponential increase back to its initial value on the same timescale. The cumulative fractional increase in the pulsar rotation rate for the three glitches amounts to Delta_nu/nu ~ 7 10^{-8}.

description: A Generalized Maximum Entropy (GME) approach is adapted to empirically estimate crop-specific production technologies in Chinese agriculture. Despite a modest behavior assumption about equal marginal returns of non-land inputs among crops, this method does not require price information, which is usually distorted in a centrally planned economy such as China. Multi-output technologies for seven regions over more than two decades are estimated, and input allocations for each province are recovered simultaneously. The estimated multi-output production technology and input allocations imply that China may have greater grain production potentials than previously thought.

description: We report on the observation of surface gravity wave turbulence at scales larger than the forcing ones in a large basin. In addition to the downscale transfer usually reported in gravity wave turbulence, an upscale transfer is observed, interpreted as the inverse cascade of weak turbulence theory. A steady state is achieved when the inverse cascade reaches a scale in between the forcing wavelength and the basin size, but far from the latter. This inverse cascade saturation, which depends on the wave steepness, is probably due to the emergence of nonlinear dissipative structures such as sharp-crested waves.

description: Temperature and velocity-dependent $^1$S$_0$ pairing gaps, chemical potentials and entrainment matrix in dense homogeneous neutron-proton superfluid mixtures constituting the outer core of neutron stars, are determined fully self-consistently by solving numerically the time-dependent Hartree-Fock-Bogoliubov equations over the whole range of temperatures and flow velocities for which superfluidity can exist. Calculations have been made for $npeμ$ in beta-equilibrium using the Brussels-Montreal functional BSk24. The accuracy of various approximations is assessed and the physical meaning of the different velocities and momentum densities appearing in the theory is clarified. Together with the unified equation of state published earlier, the present results provide consistent microscopic inputs for modeling superfluid neutron-star cores.
