description: The paper compares the effects of productivity growth in agriculture in a standard CGE model and an adjusted CGE model with special features in order to replicate partial equilibrium behavior of traded agricultural sectors within a general equilibrium framework. The fixed-price, partial equilibrium CGE model shows a strong multiplier effect so that total GDP, factor earnings, and household incomes increase with the productivity growth in agriculture. In comparison, the standard CGE model generates much more diverse sectoral behavior, stronger trade through shifts in the exchange rate, and a less equitable income distribution among farm and non-farm households.

description: We establish the representability of the general linear ${\mathbb Z}_2^n$-group and use the restricted functor of points - whose test category is the category of ${\mathbb Z}_2^n$-manifolds over a single topological point - to define its smooth linear actions on ${\mathbb Z}_2^n$-graded vector spaces and linear ${\mathbb Z}_2^n$-manifolds. Throughout the paper, particular emphasis is placed on the full faithfulness and target category of the restricted functor of points of a number of categories that we are using.

description: Stochastic Resonance in single voltage-dependent ion channels is investigated within a three state non-Markovian modeling of the ion channel conformational dynamics. In contrast to a two-state description one assumes the presence of an additional closed state for the ion channel which mimics the manifold of voltage-independent closed subconformations (inactivated ``state''). The conformational transition into the open state occurs through a domain of voltage-dependent closed subconformations (closed ``state''). At distinct variance with a standard two-state or also three-state Markovian approach, the inactivated state is characterized by a broad, non-exponential probability distribution of corresponding residence times. The linear response to a periodic voltage signal is determined for arbitrary distributions of the channel's recovery times. Analytical results are obtained for the spectral amplification of the applied signal and the corresponding signal-to-noise ratio. Alternatively, these results are also derived by use of a corresponding two-state non-Markovian theory which is based on driven integral renewal equations [I. Goychuk and P. Hanggi, Phys. Rev. E 69, 021104 (2004)]. The non-Markovian features of stochastic resonance are studied for a power law distribution of the residence time-intervals in the inactivated state which exhibits a large variance. A comparison with the case of bi-exponentially distributed residence times possessing the same mean value, i.e. a simplest non-Markovian two-state description, is also presented.

description: Continued industrialization in China and increase in its agricultural productivity imply that surplus rural workers will to be attracted into non-agricultural production activities and, consequently, will have the opportunity to increase their off-farm income. Studying the structure of the rural labor force and its characteristics is important for evaluating its migration potential into non-agricultural sectors. This study examines the rural labor market in China exclusively based on China’s first national agricultural census. We analyzed the demographic characteristics of the rural labor force and their association with the type of employment, place of work, and labor migration. Furthermore, we investigated demographic distributions of rural labor force and attempted to capture their relation with the distribution of other resources especially land availability or land constraints. We finally applied a generalized polytomous logit technique to analyze the patterns of rural labor employment and forecast rural migration. In this framework, we related rural labor migration with demographic characteristics, types of occupation, place of work, geographic characteristics, and various economic development indicators.

I concentrate on the near-infrared public surveys which will be undertaken with the Visible and Infrared Survey Telscope for Astronomy (VISTA), and in particular the VISTA Deep Extragalactic Observations (VIDEO) survey which will provide the ideal data set to combine with any deep SKA-pathfinder observations of the extragalactic sky. After highlighting the links that the SKA pathfinders have with the various VISTA surveys, I briefly describe an approved large area survey to be carried out with the Herschel Space Observatory which has a large scientific overlap with the SKA pathfinder telescopes.

description: We adapt a method, originally developed for searches for quasi-monochromatic, quasi-infinite gravitational-wave signals, to directly detect new light gauge bosons with laser interferometers, which could be candidates for dark matter. To search for these particles, we optimally choose the analysis coherence time as a function of boson mass, such that all of the signal power will be confined to one frequency bin. We focus on the dark photon, a gauge boson that could couple to baryon or baryon-lepton number, and explain that its interactions with gravitational-wave interferometers result in a narrow-band, stochastic signal. We provide an end-to-end analysis scheme, estimate its computational cost, and investigate follow-up techniques to confirm or rule out dark matter candidates. Furthermore, we derive a theoretical estimate of the sensitivity, and show that it is consistent with both the empirical sensitivity determined through simulations, and results from a cross-correlation search. Finally, we place Feldman-Cousins upper limits using data from LIGO Livingston's second observing run, which give a new and strong constraint on the coupling of gauge bosons to the interferometer.

The spectral energy distributions of these YSOs suggest young massive stars with disk, envelope, and outflow cavities. The interstellar conditions are used to assess whether the star formation was spontaneous or induced by external pressure.

description: This working paper documents the construction of a 1993-94 Social Accounting Matrix (SAM) for Bangladesh. 1 The SAM distinguishes 10 agricultural sectors—including two different kinds of rice technology—and 19 manufacturing sectors, out of 43 sectors in total. It also differentiates between twelve socio-economic groups, allowing detailed analysis of household welfare and poverty. The SAM has ten factors of production: one type of capital, one type of land and eight different types of labor which are disaggregated by both level of education and gender. The innovative feature of the SAM is that it separates out female and male labor value-added for each educational level and in each sector of the economy, providing a base for gender-sensitive analyses of policy changes. The SAM is estimated with a cross-entropy approach, which makes efficient use of all available data in a framework that incorporates prior information and constraints.

description: Liquid capillary-bridge formation between solid particles has a critical influence on the rheological properties of granular materials and, in particular, on the efficiency of fluidized bed reactors. The available analytical and semi-analytical methods have inherent limitations, and often do not cover important aspects, like the presence of non-axisymmetric bridges. Here, we conduct numerical simulations of the capillary bridge formation between equally and unequally-sized solid particles using the lattice Boltzmann method, and provide an assessment of the accuracy of different families of analytical models. We find that some of the models taken into account are shown to perform better than others. However, all of them fail to predict the capillary force for contact angles larger than $π/2$, where a repulsive capillary force attempts to push the solid particle outwards to minimize the surface energy, especially at a small separation distance.

description: Twisting two layers into a magic angle (MA) of ~1.1° is found essential to create low energy flat bands and the resulting correlated insulating, superconducting, and magnetic phases in twisted bilayer graphene (TBG). While most of previous works focus on revealing these emergent states in MA-TBG, a study of the twist angle dependence, which helps to map an evolution of these phases, is yet less explored. Here, we report a magneto-transport study on one non-magic angle TBG device, whose twist angle θ changes from 1.25° at one end to 1.43° at the other. For θ=1.25°, we observe an emergence of topological insulating states at hole side with a sequence of Chern number |C|=4-|v|, where v is the number of electrons (holes) in moiré unite cell. When θ>1.25°, the Chern insulator from flat band disappears and evolves into fractal Hofstadter butterfly quantum Hall insulator where magnetic flux in one moiré unite cell matters. Our observations will stimulate further theoretical and experimental investigations on the relationship between electron interactions and non-trivial band topology.

Subjects: subject: Astrophysics (astro-ph)

description: We present results from a comparative study of XMM-Newton observations of four classical T Tauri stars (CTTS), namely BP Tau, CR Cha, SU Aur and TW Hya. In these objects coronal, i.e. magnetic, activity and as recently shown, magnetically funneled accretion are the processes likely to be responsible for the generation of X-ray emission. Variable X-ray emission with luminosities in the order of $10^{30}$ erg/s is observed for all targets. We investigate light curves as well as medium and high-resolution X-ray spectra to determine the plasma properties of the sample CTTS and to study the origin of their X-ray emission and its variability. The emission measure distributions and observed temperatures differ significantly and the targets are dominated either by plasma at high densities as produced by accretion shocks or by predominantly hotter plasma of coronal origin. Likewise the variability of the X-ray luminosity is found to be generated by both mechanisms. Cool plasma at high densities is found in all stars with detected \ion{O}{vii} triplet emission, prevented only for SU~Aur due to strong absorption. A general trend is present in the abundance pattern, with neon being at solar value or enhanced while oxygen, iron and most other metals are depleted, pointing to the presence of the inverse FIP effect in active coronae and possibly grain formation in evolved disks. We find that both accretion shocks and coronal activity contribute to the observed X-ray emission of the targets. While coronal activity is the dominant source of X-ray activity in the majority of the CTTS, the fraction for each process differs significantly between the individual objects.

Educational discourses and teaching identities : an ethnography of being taught to teach
Creators: name: Taylor, John
Publisher: name: University of British Columbia
Year: 2009

description: Poststructuralism and discourse analysis have offered us new ways to research and understand human behaviour. Their contributions have been particularly useful for investigating individual identity or subjectivity. Poststructuralism suggests that we understand the individual as discursively positioned or constructed. When becoming who we are and acting how we do, we do so using already available discourses: ways of being, ways of knowing. We are constantly surrounded by multiple, contradictory discourses, and by consequence individual subjectivity is also changing, multiple, and contradictory. Using poststructuralism and critical discourse analysis I conducted a twelve-month ethnography of the experiences of being taught to teach. On the first of September, 1997 I began the twelve month, secondary English, teacher education program at the University of British Columbia. I employed autoethnographic and ethnographic techniques to explore some of the dominant and marginal discourses in teacher education, with a focus on my experiences and those of four other students. While there are many discourses operating in and around teacher education and schools, I examined only three: "Student Teacher as Technician," "Student Teacher as Child," and "Student Teacher as Agent for Change." The data gathered suggests a teacher education program which at its core is technocratic in nature. Students are kept so busy with largely trivial assignments and tasks that indepth engagement with educational theories and ideas is virtually impossible. Furthermore, the technocratic approach by its very nature appears to inhibit discourses related to social or educational change. In short, it could be said that students are not in a "teacher education program" but instead a "teacher training program." Perhaps one of the most significant contributions of this research is that it represents the only ethnography of teacher education conducted by a student of teacher education. This "inside" perspective may provide unique and valuable insights and offer a balance to the professorial perspective, which dominates the majority of discussions about contemporary teacher education. It is my hope that this research helps to clarify the various discourses that circulate throughout teacher education. If these discourses become more apparent to us, we can begin to understand how they act upon us to position us in particular ways as teachers and student teachers. It is also my hope that by representing a variety of ways of being a teacher, I will help to create a space in which a multiplicity of approaches to teaching are accepted and appreciated.
A no-go theorem for the persistent reality of Wigner's friend's perception

description: The notorious Wigner's friend thought experiment (and modifications thereof) has in recent years received renewed interest especially due to new arguments that force us to question some of the fundamental assumptions of quantum theory. In this paper, we formulate a no-go theorem for the persistent reality of Wigner's friend's perception, which allows us to conclude that the perceptions that the friend has of her own measurement outcomes at different times cannot "share the same reality", if seemingly natural quantum mechanical assumptions are met. More formally, this means that, in a Wigner's friend scenario, there is no joint probability distribution for the friend's perceived measurement outcomes at two different times, that depends linearly on the initial state of the measured system and whose marginals reproduce the predictions of unitary quantum theory. This theorem entails that one must either (1) propose a nonlinear modification of the Born rule for two-time predictions, (2) sometimes prohibit the use of present information to predict the future -- thereby reducing the predictive power of quantum theory -- or (3) deny that unitary quantum mechanics makes valid single-time predictions for all observers. We briefly discuss which of the theorem's assumptions are more likely to be dropped within various popular interpretations of quantum mechanics.

description: We introduce the concept of super universality in quantum Hall and spin liquids which has emerged from previous studies. It states that all the fundamental features of the quantum Hall effect are generically displayed as general topological features of the $θ$ parameter in nonlinear sigma models in two dimensions. To establish super universality in spin liquids we revisit the mapping by Haldane who argued that the anti ferromagnetic Heisenberg spin $s$ chain is effectively described by the O(3) nonlinear sigma model with a $θ$ term. By combining the path integral representation for the dimerized spin $s=1/2$ chain with renormalization group decimation techniques we generalise the Haldane approach to include a more complicated theory, the fermionic rotor chain, involving four different renormalization group parameters. We show how the renormalization group calculation technique can be used to lay the bridge between the fermionic rotor chain and the sigma model. As an integral and fundamental aspect of the mapping we establish the topological significance of the dangling spin at the edge of the chain which is in all respects identical to the massless chiral edge excitations in quantum Hall liquids. We consider various different geometries of the spin chain and show that for each of the different geometries correspond to a topologically equivalent quantum Hall liquid.

description: The characteristics of the Solid-state Neutron Detector, under development for neutron-scattering measurements at the European Spallation Source, have been simulated with a Geant4-based computer code. The code models the interations of thermal neutrons and ionising radiation in the 6Li-doped scintillating glass of the detector, the production of scintillation light and the transport of optical, scintillation photons through the the scintillator, en route to the photo-cathode of the attached multi-anode photomultiplier. Factors which affect the optical-photon transport, such as surface finish, pixelation of the glass sheet, provision of a front reflector and optical coupling media are compared. Predictions of the detector response are compared with measurements made with neutron and gamma-ray sources, a collimated alpha source and finely collimated beams of 2.5 MeV protons and deuterons.

description: This paper analyzes price, production and trade consequences of changing consumer preferences regarding the use of genetically modified organisms (GMOs) in food production. The analytical framework used is an empirical global general equilibrium model, in which the entire food processing chain – from primary crops through livestock feed to processed foods – is segregated into genetically modified (GM) and non-GM lines of production. This model is used to analyze the implications of widespread use of genetically engineered crops in some regions whilst consumers in Western Europe and High- income Asia adopt a critical attitude toward GM foods. Two different representations of consumer preference changes are illustrated: (1) a change in price sensitivity: i.e. consumer demand is less sensitive to a decline in the price of GM foods relative to non-GM varieties, and (2) a structural demand shift: for a given price ratio consumers simply demand less of the GM variety relative to the non-GM variety. This analysis finds that developing countries adjust their trade patterns in response to preference changes in important trading partner countries. Non-GM varieties are diverted to GM-critical regions while GM varieties are sold to countries in which consumers are not sensitive to GM content. Furthermore, the development of segregated GM and non-GM food creates a potential niche market for producers if the non-GM characteristic can in fact be preserved and verified throughout the marketing system at reasonable costs.
The Monopole Moment of the Three-Point Correlation Function of the 2-degree Field Galaxy Redshift Survey

description: We measure the monopole moment of the three-point correlation function on scales $1\mpc-70\mpc$ in the Two degree Field Galaxy Redshift Survey (2dFGRS). Volume limited samples are constructed using a series of integral magnitudes bins between $M = -18 ... -22$. Our measurements with a novel edge-corrected estimator represent most, if not all, three-point level monopole or angular averaged information in the catalogue. We fit a perturbative non-linear bias model to a joint data vector formed from the estimated two- and three-point correlation functions. Two different models are used: an analytic model based on Eulerian perturbation theory including bias and redshift distortions, and a phenomenological bias model based on the direct redshift space measurements in the large Virgo simulations. To interpret the clustering results, we perform a three parameter Gaussian maximum likelihood analysis. In the canonical $-21 \sim -20$ volume limited sample we find $σ_8 = 0.93^{+0.06}_{-0.2}$, $b = 1.04^{+0.23}_{-0.09}$, and $b_2 = -0.06^{+0.003}_{-0.001}$. Our estimate of $σ_8$, is robust across the different volume limited samples constructed. These results, based solely on the large scale clustering of galaxies, are in excellent agreement with previous analyses using the Wilkinson Anisotropy Probe: this is a spectacular success of the concordance model. We also present two-parameter fits for the bias parameters, which are in excellent agreement with previous findings of the bias evolution in the 2dFGRS.

description: Turbot, Psetta maxima (Linnaeus, 1758), is a flatfish of the family Scophthalmidae, which is widespread in the North Atlantic, Mediterranean and Black Seas (Nielsen, 1986). The species inhabits European coastal waters in the North Atlantic from Norway to Morocco, including the Baltic, Mediterranean and the Black Sea (Blanquer et al., 1992). It is a benthic marine species, inhabiting a sandy and muddy bottom, in the shallower part of the continental shelf up to about 110 meters (Karapetkova, 1964). Sahin & Gunes (2011) claim that Psetta maxima is widespread in the coastal zone at a depth of 20-60 m. The present study aims to address various aspects of the distribution and abundance of turbot through landing data. Based on the analysis of the information from turbot catches, we obtained information, which is crucial for science and it is useful for the management of fishing activities and quotas. The data for the study is collected from the Bulgarian ports in the Black Sea in the period 2017-2019. Samples of 2062 fish are collected. The average total length and weight of the fish are 52.63 ± 6.12 cm and 2600 ± 910 g respectively. The length-weight ratios are determined by the following equations: 2017 – W=0.02.L2.98, n=566, (R2=0.88); 2018 – W=0.04.L2.80, n=783, (R2 = 0.85); 2019 – W=0.34.L2.25, n=713, (R2 = 0.71); 2017 – 2019: W=0.08.L2.60, n=2062, (R2= 0.80). Based on the data analyzed in the study, Psetta maxima has healthy population in the Bulgarian waters of the Black Sea.

description: This paper predicting Trump victory has been submitted before the election and revised after, allowing to add a Foreword and Note Added in Revision to discuss in details the causes of the failure of the prediction. In 2016, Trump was unanimously seen as the loser in the November 8 election. In contrast, using a model of opinion dynamics I have been developing for a few decades within the framework of sociophysics, I predicted his victory against all odds. According to the model, the winning paradoxical martingale of 2016, has been Trump capability to activate frozen prejudices in many voters by provoking their real indignation. However, four year later, Trump shocking outings do not shock anymore, they became devitalized, losing their ability to generate major emotional reactions. Does this mean that this time around he will lose the 2020 election against Biden, as nearly all analysts, pundits and commentators still predict? No, because with frozen prejudices remaining frozen, the spontaneous prejudices will be activated but this time they will benefit to both Biden and Trump. The main ones are the fear of the other candidate policy and the personal stand facing a danger. In addition, Trump presidency having polarized a large part of American voters into narrow-minded anti-Trump and narrow-minded pro-Trump, those I denote in my model as inflexibles, will be driving the dynamics of choices. Both effects, prejudices and inflexibles can either compete or cooperate making their local combination within each state, decisive to determine the faith of the state election. As a result, tiny differences can make the outcome. Based on my rough estimates of associated proportions of inflexibles and prejudices, the model predicts Trump victory in the 2020 November election.

description: We analyze the implications of the HIV/AIDS pandemic in Tanzania for labor markets and human capital accumulation. Three analyses are undertaken. First, we examine the 2000/01 Labor Force Survey and compare it with the 1990/91 Labor Force Survey. Since these two surveys encompass a period where accumulated AIDS deaths increased dramatically, their comparison provides an opportunity to make inferences about the impact of HIV/AIDS over that period. Second, we study rates of human capital accumulation, proxied by educational attainment, for the period 1991 to 2000. While the most obvious impact of HIV/AIDS on human capital comes about through the deaths of skilled people, this might not be the greatest concern in terms of long run economic impact. In poor countries with low levels of human capital, implications for rates of human capital accumulation might be of greater concern. We estimate education transition matrices to assess human capital accumulation over the 1990s and assess the trends in transition probabilities and regional variations in these trends. Finally, we analyze the implications of skills upgrading using a computable general equilibrium (CGE) model of Tanzania. We find that the age structure of the labor force is changing with 10-14 year olds and juveniles comprising a significantly larger share and prime age adults aged 20-35 a smaller share compared with 1990/91. The growth in the child and juvenile labor force is matched by a trend towards an increased tendency to exit primary school and an overall lower share of children aged 5-14 enrolled in primary school. We conclude that workforce experience and rates of human capital accumulation are declining with HIV/AIDS being a prime factor underlying these trends. The CGE analysis indicates that skills upgrading of the population has particularly large first order (segmented rural and urban labor markets) impacts on the agricultural sector since the large majority of the population is rural. If migration is permitted, the enhanced productivity of a more skilled rural labor force permits substantial growth in agricultural and non-agricultural output generating a development pattern similar to those advocated by Mellor (1976) and Adelman et al. (1989). Reduced rates of skills upgrading would slow these trends.

description: In this paper, we present a comparative analysis of the extent to which indirect taxes, tariffs, and exchange rates affected relative price incentives for agricultural production in a representative sample of 15 developing countries in the 1990s. Empirical studies from the 1980s, using partial equilibrium methodologies, supported the view that policies in many developing countries imparted a major incentive bias against agriculture. Eliminating this bias was one of the goals of policy reform strategies, including structural adjustment programs, supported by the World Bank and others; and many countries undertook such reforms in the 1990s. In our sample, general equilibrium analysis indicates that, in the 1990s, the economywide system of indirect taxes, including tariffs and export taxes, significantly discriminated against agriculture in only one country, was largely neutral in five, provided a moderate subsidy to agriculture in four, and strongly favored agriculture in five. Earlier work assumed that overvaluation of the exchange rate would hurt agriculture, which was assumed to be largely tradable. In a general equilibrium setting, changes in the exchange rate can as demonstrated in this paper lead to anything between strongly increasing and decreasing relative agriculture/non-agriculture incentives, depending on relative trade shares. We conclude that, whatever incentive bias there was in the 1980s, it has mostly disappeared by the 1990s. We also find that it is difficult to generalize.country specific circumstances greatly affect the relative impact of trade policies on agriculture and the rural economy.

description: In this paper we investigate a class of decoupled forward-backward SDEs, where the volatility of the FSDE is degenerate and the terminal value of the BSDE is a discontinuous function of the FSDE. Such an FBSDE is associated with a degenerate parabolic PDE with discontinuous terminal condition. We first establish a Feynman-Kac type representation formula for the spatial derivative of the solution to the PDE. As a consequence, we show that there exists a stopping time τsuch that the martingale integrand of the BSDE is continuous before τand vanishes after τ. However, it may blow up at τ, as illustrated by an example. Moreover, some estimates for the martingale integrand before τare obtained. These results are potentially useful for pricing and hedging discontinuous exotic options (e.g., digital options) when the underlying asset's volatility is small, and they are also useful for studying the rate of convergence of finite-difference approximations for degenerate parabolic PDEs.

description: We observe monopole oscillations in a mixture of Bose-Einstein condensates, where the usually dominant mean-field interactions are canceled. In this case, the system is governed by the next-order Lee-Huang-Yang (LHY) correction to the ground state energy, which describes the effect of quantum fluctuations. Experimentally such a LHY fluid is realized by controlling the atom numbers and interaction strengths in a $^{39}$K spin mixture confined in a spherical trap potential. We measure the monopole oscillation frequency as a function of the LHY interaction strength as proposed recently by Jørgensen et al. [Phys. Rev. Lett. 121, 173403 (2018)] and find excellent agreement with simulations of the complete experiment including the excitation procedure and inelastic losses. This confirms that the system and its collective behavior are initially dominated by LHY interactions. Moreover, the monopole oscillation frequency is found to be stable against variations of the involved scattering lengths in a broad region around the ideal values, confirming the stabilizing effect of the LHY interaction. These results pave the way for using the non-linearity provided by the LHY term in quantum simulation experiments and for investigations beyond the LHY regime.

HOW CHINA'S WTO ACCESSION AFFECTS RURAL ECONOMY IN THE LESS-DEVELOPED REGIONS: A MULTI-REGION, GENERAL EQUILIBRIUM ANALYSIS

description: This study constructs a regional CGE model of China to analyze the differential regional impacts of China’s WTO accession on agricultural production, trade, and farmers’ income. The results show that China’s WTO accession will generally improve the total welfare but will widen existing gaps among regions and sectors. It is expected that the agricultural sector will suffer if only agricultural trade is liberalized, as cheap imports of agricultural products, particularly grains, will increase and domestic agricultural production and farmers’ agricultural income will decline. Full trade liberalization, i.e., lifting trade barriers in both agriculture and non-agriculture will benefit farmers and agriculture at the national level. However, the increase in rural income is still smaller than the increase in urban income, which implies that the rural-urban income gap may be further widened. Furthermore, among the regions, the less-developed rural areas will benefit little or even suffer because their major production activities and income sources are still from agriculture, especially from traditional agricultural activities such as grain production.
