description: Ground state properties of condensed Helium are calculated using the Path Integral Ground State (PIGS) method. A fourth-order approximation is used as short (imaginary) time propagator. We compare our results with those obtained with other Quantum Monte Carlo techniques and different propagators. For this particular application, we find that the fourth-order propagator performs comparably to the pair product approximation, and is far superior to the primitive approximation. Results obtained for the equation of state of condensed Helium show that PIGS compares favorably to other QMC methods traditionally utilized for this type of calculation.
Mathematical understanding and Tongan bilingual students’ language switching : is there a relationship?
Creators: name: Manu, Sitaniselao Stan
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the relationship between Tongan bilingual students' language switching and their growth of mathematical understanding. The importance of this study lies not only in its ability to use the Pirie-Kieren Dynamical Theory for the Growth of Mathematical Understanding as a theoretical tool for examining the relationship between language switching and growth of mathematical understanding, but also in its ability to demonstrate the theory's applicability and validity in a bilingual context. Video case study was chosen as the most appropriate means of recording, collecting and examining the described relationship in a small-group setting. Two strands of data were collected between 2001 and 2002 from a selected number of bilingual students from five secondary schools in Tonga. Analysis of the students' language switching through the Constant Comparative Method resulted in the categorization of four main "forms" of language switching. These forms were identified, categorized, and developed from the data to provide a language for describing and accounting for the particular way Tongan students switch languages. The evidence from the data clearly demonstrates how language switching both did and did not influence and was and was not influenced by the students' growth of understanding through the construction of mathematical meanings. At the same time, language switching was found to definitely enable the expression of growth of mathematical understanding. This study proposes that the effect of bilingual students' learning and development of understanding in mathematics is largely dependent on the kinds of mathematical images each bilingual student associates with his or her language. Therefore this study introduces the notion of "evocative" language switching, used for identifying, retrieving, and guiding one's existing understanding and ability to work with images. The evidence from this study is certainly applicable to other Tongan-type bilingual situations that involve individuals using words with no direct or precise translation between a dominant Western language and an indigenous language. Ultimately, the findings of this study challenge the assumption that Tongan-type bilingual students have enormous problems in the classroom. Allowed the flexibility of language switching and thus access to appropriate terms and images in either language, they do not seem to be mathematically disadvantaged.

description: Taking Chongqing as example, the paper ascertains the influencing factors of cultivation land intensive use from aspects of land conditions, family conditions and land operation conditions and theoretically expects the influencing relations of factors to the intensive uses. Collecting the land conditions, family conditions and land operation conditions through surveys, analyzes each influencing factors in a statistical description way. Constructing the empirical model, calculates the relations of land intensive use to the influencing factors with SPSS. The calculation results show a significant inverse correlation between land intensive use and land area, the space between land and counties, family members, the number of migrant workers, types of cultivation land, land transfer conditions. There is a significant positive correlation between land use and family average income, land investment. Based on these, the paper put forwards corresponding suggestions and countermeasures of highlighting the land intensive using levels.

description: The Abell cluster of galaxies A3667 was observed with XMM-Newton in 6 partially overlapping pointings. We present here the resulting X-ray surface brightness, temperature, entropy and pressure maps and discuss the structure of this cluster on scales from 0.1 to 30 arcminutes. Based on these observations we refine the origin of the A3667 cold front to the displacement of the low entropy, high metal abundance gas from the current pressure peak of the cluster. We argue that the mushroom shape of the cold front observed here is similar to what is seen in some numerical simulations. We also present the first evidence for a dynamically significant angular momentum in the cold front.

description: Based on the data from the Qinghai Statistical Yearbook 2009, the evolution course of industrial structure and the developmental status of pillar industry is analyzed. The pillar industries in Qinghai Province are analyzed and revaluated from four aspects, which cover demand and income elasticity, location quotient, contribution rate and interrelationship between industries. Through analyzing the problems and causes of the industrial structure of Qinghai Province, we know that the output structure of the three main industries has seriously departed from the employment structure; the pillar industries mainly concentrated on the fields of resource exploitation and primary processing; the interrelationship between the industries is low; and the development between the light and heavy industries are imbalanced. With the globalization and the further implementation of national preferential policies on western development, Qinghai Province follows the following principles in the restructuring of industrial structure in order to carry out the scientific thought of development and the “Ecological province” strategy. Firstly, the restructuring of industrial structure should be guided by market and scientific and technological progress. Secondly, it should fully display the regional advantages. Thirdly, it should attach importance to the developmental status and prospect of relevant accessory industries. Fourthly, the restructuring should be helpful to the labor transfer and reemployment of rural surplus labor forces. Suggestions on the selection of pillar industries and optimization of industrial structure are put forward. Qinghai Province should accelerate the restructuring of industrial structure, strengthen the support on pillar industries and lay stress on the introduction of the capitals, technologies and talents.

description: In this paper we investigate the speed of convergence of the fluctuations of a general class of Feynman-Kac particle approximation models. We design an original approach based on new Berry-Esseen type estimates for abstract martingale sequences combined with original exponential concentration estimates of interacting processes. These results extend the corresponding statements in the classical theory and apply to a class of branching and genealogical path-particle models arising in nonlinear filtering literature as well as in statistical physics and biology.

description: The van der Waals coefficients, from C_11 through to C_16 resulting from 2nd, 3rd and 4th order perturbation theory are estimated for the alkali (Li, Na, K and Rb) atoms. The dispersion coefficients are also computed for all possible combinations of the alkali atoms and hydrogen. The parameters are determined from sum-rules after diagonalizing the fixed core Hamiltonian in a large basis. Comparisons of the radial dependence of the C_n/r^n potentials give guidance as to the radial regions in which the various higher-order terms can be neglected. It is seen that including terms up to C_10/r^10 results in a dispersion interaction that is accurate to better than 1 percent whenever the inter-nuclear spacing is larger than 20 a_0. This level of accuracy is mainly achieved due to the fortuitous cancellation between the repulsive (C_11, C_13, C_15) and attractive (C_12, C_14, C_16) dispersion forces.

description: As the greatest rainwater users among all vegetative land covers, tree plantations have been employed strategically to mitigate salinity and water-logging problems. However, large-scale commercial tree plantations in high rainfall areas reduce fresh water inflows to river systems supporting downstream communities, agricultural industries and wetland environmental assets. A bio-economic model was used to estimate economic demand for water by future upstream plantations in a sub-catchment (the 2.8 million ha Macquarie valley in NSW) of the Murray-Darling Basin, Australia. Given four tree-product values, impacts were simulated under two settings: without and with the requirement that permanent water entitlements be purchased from downstream entitlement holders before establishing a tree plantation. Without this requirement, gains in economic surplus from expanding tree plantations exceeded economic losses by downstream irrigators, and stock and domestic water users, but resulted in reductions of up to 154 GL (gigalitres) in annual flows to wetland environments. With this requirement, smaller gains in upstream economic surplus, added to downstream gains, could total $330 million while preserving environmental flows. Extending downstream water markets to new upstream tree plantations, to equilibrate marginal values across water uses, helps ensure water entitlements are not diminished without compensation. Outcomes include better economic-efficiency, social-equity and environmental-sustainability.

description: We present the first spectroscopic observations in the interval 0.8-4.0 microns, complemented with HST/UV and optical spectroscopy, of the narrow line Seyfert 1 galaxy Mrk766. The NIR spectrum is characterized by permitted lines of HI, HeI, HeII and FeII, and forbidden lines of [SII], [SIII] and [FeII] among others. High ionized species such as [SiIX], [SiX], [SIX] and [MgVII] are also observed. The continuum has a complex shape, with contribution of the central engine, circumnuclear stellar population and dust. This last component is evidenced by the presence of an excess of emission peaking at 2.25 microns, fitted by blackbody function with T_bb=1200K. That temperature is close to the evaporation temperature of graphite grains. As such, it provides strong evidence of hot dust, probably very close to the nucleus. Consistent modeling of the line and broad band continuum spectrum by composite models, which account for the photoionizing flux of the central engine and shocks, shows that the shock velocities are between 100 and 500 km/s, the preshock densities between 100 and 1000 cm^-3 and the radiation fluxes from the active centre between 10^9 and 5x10^12 photons cm^-2 s^-1 eV^-1 at 1 Ryd with spectral indices $α_{UV}$=-1.5 and $α_X$=-0.4. Adopting silicon grains, dust-to-gas ratios are between 10^-{6} and 4x10$^{-4}$ by mass. The emitting clouds are at an average distance of 160 pc from the centre, with high velocity clouds closer and low velocity clouds farther from the centre. The N/H relative abundance could be twice solar. In constrast, Fe is depleted from the gaseous phase by a factor >2. Ratios of calculated to observed line ratios to Hbeta indicate an average contribution of the broad line region to the observed Hbeta of about 40%.

More water for everything? The problem of bogus water savings in northern Victoria, Australia

description: The Victorian Department of Sustainability and Environment (DSE) spent the latter decades of the 20th century fully integrating the surface and sub-surface drainage systems with the water distribution network in northern Victoria, thereby enabling complete recycling of outfalls, leaks and seepage from its channels. Yet in 2007, in repudiation of this recycling capacity, DSE announced a multibillion dollar modernisation project it claims will “create” 450 GL of “new water” by reducing “inefficiencies” in the channel distribution system. Examination of the northern Victorian irrigation supply system shows it was fully integrated with more than adequate recycling capacity before the project began. In a classic case of double counting, DSE was already delivering the illusory “new water” to regional irrigators and billing them for it. Thus the project cannot deliver real water savings and the Government must effectively reduce irrigation entitlement to increase entitlements for urban consumption and environmental flows. The financial and economic impact of bogus water savings on stakeholders is discussed in terms of the opportunity cost of appropriated irrigation entitlement and of the effect of overcapitalisation of the distribution system on annual capital charges and thus the viability of irrigation and the operating water authority.

description: Singular value decomposition is central to many problems in engineering and scientific fields. Several quantum algorithms have been proposed to determine the singular values and their associated singular vectors of a given matrix. Although these algorithms are promising, the required quantum subroutines and resources are too costly on near-term quantum devices. In this work, we propose a variational quantum algorithm for singular value decomposition (VQSVD). By exploiting the variational principles for singular values and the Ky Fan Theorem, we design a novel loss function such that two quantum neural networks (or parameterized quantum circuits) could be trained to learn the singular vectors and output the corresponding singular values. Furthermore, we conduct numerical simulations of VQSVD for random matrices as well as its applications in image compression of handwritten digits. Finally, we discuss the applications of our algorithm in recommendation systems and polar decomposition. Our work explores new avenues for quantum information processing beyond the conventional protocols that only works for Hermitian data, and reveals the capability of matrix decomposition on near-term quantum devices.

description: The Chinese "coal-to-gas" strategy aims at reducing coal consumption and related air pollution by promoting the use of clean and low carbon fuels in northern China. Here we show that on top of meteorological influences, these measures achieved an average decrease of fine particulate matter (PM2.5) concentrations of ~14% during winter 2017 in Beijing and surrounding areas (the "2+26" pilot cities). However, the localized air quality improvement was accompanied by a contemporaneous ~15% upsurge of PM2.5 concentrations over large areas in southern China. We find that the pollution transfer that resulted from a shift in emissions was caused by a natural gas shortage in the south due to the "coal-to-gas" transition in the north. The overall shortage of natural gas greatly jeopardized the air quality benefits of the "coal-to-gas" strategy in winter 2017 and reflects structural challenges and potential threats in China's clean energy transition.

Internal Innovation and Informational Dynamics within Small and Medium Beef Cattle Farm Enterprises

Year: 2011
Subjects: Farm Management

description: The internal knowledge capabilities of small and medium beef cattle farm enterprises are examined using information economics to gain an understanding of how these organisations approach innovation. Enterprises are viewed as being embedded in the wider industry and are subject to both external and internal influences. However the discussion here is focused on internal activities in order to consider how enterprise specific knowledge is constructed allowing innovation to occur. Innovation is an incremental and continuous process because of the endogenous origins of the internally developed knowledge used to enact it. Learning theory is incorporated into this analysis to elucidate this connection between production undertaken and the historical shaping of knowledge capabilities into enterprise specific knowledge. Routines are introduced as units of analysis to show how resources are internally organised according to the knowledge producers possess. Routines provide a method of looking at processes by explicitly considering the time dimension while including the complex farming environment as a physical and biologically conditioned system. Analysis of changing routines through learning theory shows there are internal motivations for innovation directly attributable to the internal productive nature of beef cattle farm enterprises. Data has been sourced from in-depth interviews and focus groups conducted with producers in the New England area of New South Wales. Results show that much innovative activity is informal and not recorded; producers develop extensive knowledge in accordance with the physical capital they possess; and individual innovations should be considered as collections of ongoing refinements.
Generalization of Child-Langmuir Law for Non-Zero Injection Velocities in a Planar Diode

description: The Child-Langmuir law relates the voltage applied across a planar diode to the saturation value J_CL of current density that can be transmitted through it in case the injection velocity of electrons into the diode is zero. The Child-Langmuir current density J_CL is, at the same time, (i) the maximum current density that can be transmitted through a planar diode, (ii) the current density below which the flow is steady and unidirectional in the long time limit and (iii) the average transmitted current density for {\em any} value of injected current density above J_CL. Existing generalizations of Child-Langmuir law to non-zero velocities of injection are based on the characteristics (i) and (ii) of J_CL. This paper generalizes the law to non-zero velocities of injection based on the characteristic (iii) by deriving an analytical expression for the saturation value of current density. The analytical expression for the saturation current density is found to be well supported by numerical computations. A reason behind preferring the saturation property of the Child-Langmuir current density as the basis for its generalization is the importance of that property in numerical simulations of high current diode devices.

description: Efficient multilayer optics for radiation in the water window range are difficult to manufacture due to extremely small layer thicknesses and severe intermixing of elements between the layers. Therefore, adequate analytics and short feedback loops are of utmost importance for manufacturers to improve performance and efficiency. We show the possibility for non-destructive elemental depth profiling with commercial laboratory equipment using four real-life CrSc multilayer samples. Comparative measurements at the laboratory of PTB at the synchrotron radiation facility BESSY II confirm the results and prove the potential of laboratory equipment for the reliable analysis of stratified materials with sub-nanometer layer thicknesses.

description: Due to structural incommensurability, the emergence of a quasicrystal from a crystalline phase represents a challenge to computational physics. Here the nucleation of quasicrystals is investigated by using an efficient computational method applied to a Landau free-energy functional. Specifically, transition pathways connecting different local minima of the Lifshitz-Petrich model are obtained by using the high-index saddle dynamics. Saddle points on these paths are identified as the critical nuclei of the 6-fold crystals and 12-fold quasicrystals. The results reveal that phase transitions between the crystalline and quasicrystalline phases could follow two possible pathways, corresponding to a one-stage phase transition and a two-stage phase transition involving a metastable lamellar quasicrystalline state, respectively.

However, aggregate contract use has stabilized in recent years and no longer suggests a strong trend. Contracts between farmers and their buyers are reached prior to harvest (or before the completion stage for livestock)and govern the terms under which products are transferred from the farm. Contracts are far more likely to be used on large farms than on small farms, and they form one element in a package of risk management tools available to farmers. Production contracts are used widely in livestock production, while marketing contracts are important to the production of many crops.

description: We measure the geometry of a crumpled sheet of paper with laser-aided topography and discuss its statistical properties. The curvature of an elasto-plastic fold scales linearly with applied force. The curvature distribution follows an exponential form with regions of high curvature localized along ridges. The measured ridge length distribution is consistent with a hierarchical model for ridge breaking during crumpling. A large fraction of the ridges are observed to terminate without bifurcating and the ridge network connectedness is not as complete as anticipated. The self-affinity of the surface is characterized by a Hurst exponent of $0.72\pm 0.01$ in contrast with previous results.

Engaging women’s history through textiles : enhancing curricula with narratives of historical memory
Creators: name: Wheeler, Eileen Margaret
Publisher: name: University of British Columbia
Year: 2009

description: In this interpretive study I bring aspects of women's history into sharper focus by examining the close historical relationship with textiles that has featured in the lives of many women. By engaging the manifestations of this relationship, the creative work or the associated stories of selected women, I demonstrate that 'textile narratives' are historical sources that together with the study of objects provide more delineation of women's lives in a historical frame that can enhance the teaching of women's history. Many facets of history now more fully reflect the lives of women yet a fuller delineation is needed. Textiles are meaning-laden objects that are under-appreciated and under-utilized in the teaching of history. Literature is lacking that specifically addresses how textiles and the stories associated with them can be used as sources to augment the teaching of history, particularly women's history. Through a methodology that draws on the conceptual framework of memory study, examples, including one from suffrage history, demonstrate the analysis of textiles as historical sources. Three narratives that reflect women's negotiation of historical circumstance are examined in detail through their textiles, objects of memory and stories. Through a qualitative analysis of elements that emerge from the oral history and material culture of women's lives, agency is identified as a core attribute in their individual selection and articulation of memory in textiles. A n analysis of the narratives demonstrates the value of textiles as a means to shed light on marginalized histories. A theoretical grounding with reference to practice demonstrates how textiles are used as a means to communicate knowledge, history and identity and how these might be adapted to enrich curricula that strives to integrate women's history, gather new knowledge through narratives of memory and hear more women's voices. Through the appealing story form, these humanizing narratives and their analysis provide a model to gather details of women's lives for a more nuanced history. I suggest ways to integrate this knowledge into an inclusive democratic model of curricula through interdisciplinary approaches that can engage students and simultaneously centre more history on women ameliorating their marginalization.

description: Federal dietary guidance advises Americans to consume more vegetables and fruits because most Americans do not consume the recommended quantities or variety. Food prices, along with taste, convenience, income, and awareness of the link between diet and health, shape food choices. We used 2008 Nielsen Homescan data to estimate the average price at retail stores of a pound and an edible cup equivalent (or, for juices, a pint and an edible cup equivalent) of 153 commonly consumed fresh and processed fruits and vegetables. We found that average prices ranged from less than 20 cents per edible cup equivalent to more than $2 per edible cup equivalent. We also found that, in 2008, an adult on a 2,000- calorie diet could satisfy recommendations for vegetable and fruit consumption in the 2010 Dietary Guidelines for Americans (amounts and variety) at an average price of $2 to $2.50 per day, or approximately 50 cents per edible cup equivalent.

description: Nowadays, innovation is no longer limited to the individual firm but involves increasingly the chain network in which the firm is embedded. The chain network is considered as the place where the internal and external resources of a firm are combined and transformed, leading to innovation capacity. In the increasingly globalizing market, innovation is an important strategic tool for small and medium sized enterprises (SMEs) to achieve competitive advantage. However, SMEs are often confronted with barriers for developing and introducing innovations, such as the lack of economies of scale. Our paper investigates how the chain network is contributing to the enhancement of the innovation capacity and which chain network characteristics are crucial in this process. In contrast to previous studies at chain network level, in our research specific chain networks are investigated and compared to each other. Hence, data collection took place at different chain network levels, being the supplier, the food manufacturer and the customer, working together and consequently belonging to one specific and unique chain network. The analysis of innovation capacity at the chain network level is realized by means of cluster analysis. This results in a three-cluster solution dividing the sample into Non-innovator chain networks, Customer-driven innovator chain networks and food manufacturer-supplier-driven innovator chain networks. Next, the influence of the chain network on the innovation capacity is examined. Thereby, the three achieved clusters differ significantly related to certain chain network characteristics. The following characteristics form an important leverage for the innovation capacity: firm size, profitability and business growth of the chain network members, as well as higher dependency, and lower levels of integration, rewarding power, social satisfaction and collaboration. The distinction of Customer-driven and food manufacturer-supplier-driven innovator chain networks reveals that the involvement of the chain network partners for the enhancement of the innovation capacity is a very important aspect. In future research, the degree of complexity of the studied system should gradually be increased, namely from a chain network of three members to more complex chain networks.

description: The rotational evolution of cool dwarfs is poorly constrained after around 1-2 Gyr due to a lack of precise ages and rotation periods for old main-sequence stars. In this work we use velocity dispersion as an age proxy to reveal the temperature-dependent rotational evolution of low-mass Kepler dwarfs, and demonstrate that kinematic ages could be a useful tool for calibrating gyrochronology in the future. We find that a linear gyrochronology model, calibrated to fit the period-Teff relationship of the Praesepe cluster, does not apply to stars older than around 1 Gyr. Although late-K dwarfs spin more slowly than early-K dwarfs when they are young, at old ages we find that late-K dwarfs rotate at the same rate or faster than early-K dwarfs of the same age. This result agrees qualitatively with semi-empirical models that vary the rate of surface-to-core angular momentum transport as a function of time and mass. It also aligns with recent observations of stars in the NGC 6811 cluster, which indicate that the surface rotation rates of K dwarfs go through an epoch of inhibited evolution. We find that the oldest Kepler stars with measured rotation periods are late-K and early-M dwarfs, indicating that these stars maintain spotted surfaces and stay magnetically active longer than more massive stars. Finally, based on their kinematics, we confirm that many rapidly rotating GKM dwarfs are likely to be synchronized binaries.

description: We analyze a (1+1)-dimension directed random walk model of a polymer dipped in a medium constituted by two immiscible solvents separated by a flat interface. The polymer chain is heterogeneous in the sense that a single monomer may energetically favor one or the other solvent. We focus on the case in which the polymer types are periodically distributed along the chain or, in other words, the polymer is constituted of identical stretches of fixed length. The phenomenon that one wants to analyze is the localization at the interface: energetically favored configurations place most of the monomers in the preferred solvent and this can be done only if the polymer sticks close to the interface. We investigate, by means of large deviations, the energy-entropy competition that may lead, according to the value of the parameters (the strength of the coupling between monomers and solvents and an asymmetry parameter), to localization. We express the free energy of the system in terms of a variational formula that we can solve. We then use the result to analyze the phase diagram.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
