description: The results of studies of melting and crystallization processes in Bi-Ge layered film system are presented. These systems were prepared by subsequent condensation of components in vacuum. It has been shown that the melting temperature in system under study decreases with the decrease of Bi film thickness. The differential technique used for melting temperature registration enables us to measure the value of eutectic temperature $T_ε$ = 542 K in the system. The values of supercooling upon crystallization ($ΔT$ = 93 K) and wetting angle ($θ= 68^\circ$) have been determined for Bi islands on amorphous Ge substrate.

DERIVED DEMAND ELASTICITIES: MARKETING MARGIN METHODS VERSUS AN INVERSE DEMAND MODEL FOR CHOICE BEEF

Year: 1991
Subjects: Demand and Price Analysis

description: Three methods of calculating the derived elasticity of demand for Choice slaughter beef are used: (a) a traditional marketing margin approach, (b) a modified marketing margin approach, and (c) an econometric, inverse demand model approach. The first method is more restrictive than the second but both tend to overestimate beef price flexibility and revenue changes. The econometric model, though an incomplete demand system, yields demand elasticities that are more consistent with marketing flexibility but are less pronounced than estimates of a complete system. An example using a two-year revenue forecast compares slaughter revenue adjustments based on the first margin method with those based on structural demand models.

description: We have developed a semi-analytical theory for low-altitude lunar orbits with the aim of verifying what the minimum order of the gravitational model to be considered should be in order to produce realistic results that can be applied to the analysis and design of real missions. With that purpose, we have considered a perturbation model that comprises a 50x50 gravitational field and the third-body attraction from the Earth. Initially, the process of developing the theory is briefly described. Then, the discussion is focused on the search for frozen orbits, for which the effect of each harmonic term of the gravitational model is analyzed separately. As higher-order zonal harmonics are included, new families of frozen orbits can appear. In addition, the eccentricity and inclination values for which frozen orbits can exist change. This effect is very important and needs to be taken into consideration, because ignoring high-order harmonics can lead to predict the existence of frozen orbits at certain inclinations at which the frozen-orbit eccentricity actually falls beyond the impact limit. Consequently, it has been verified that, in agreement with other authors, a 50x50 gravitational model should be the minimum to be considered for real applications.

Tarrying in metonymic sites of pedagogy : the space of language and the language of space
Creators: name: Palulis, Patricia Adele
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation works and is worked by the chiasmus in-between the language of space and the space of language. Fragmented narratives of live(d) experience from the everyday life of pedagogy are juxtaposed with theoretical traces from Lacanian psychoanalysis and Derridean deconstruction. The text(ure) of the work labours with and against the grain of hegemonic inscriptions in multiple sites of pedagogy - tarrying within uncertainty - on the tremulous grounds of a 'third' discourse. Located always already within the materiality of language, the work labours within spaces of provocative dissonance in-between theoretical positionings. Readings of spatiality from architecture and human geography intersect and disseminate with readings of language from post/colonial ethnography and cultural studies. Rereadings resonate within the vibrancy of a growing literature on writing otherwise within the spaces of interdisciplinarity. Reading outside the literature of pedagogy infuses the inside writing as boundaries are disturbed and subjectivities destabilized. Research is rewritten as messy text as/in a rigour of ruins in the gaps and intervals of the spaces in-between. As semiotic tropes of language shift toward performativity, the text ex-scribes in order to disrupt the circumscriptions of normative praxis. The text seeks invocations for risking radical responsibilities in the everyday experience of living pedagogy - in the tensionaliry of the always already and the not-yet there. The work of this dissertation labours beneath and beyond the text in semiotic dispositions - through an Aokian re-reading of Lacanian metonymy for pedagogy - a doubling movement of metonymy/metaphor in tropic moments - within a 'third' discourse generating openings for transformation. Excentric circumscriptions dis/appear into the space of no-thingness - a site of ambiguity that is both thing and nothing and yet neither thing nor nothing - an ongoing response to an invitation to write a paper/not paper. A writing that tarries within its inscription - ghosted by a reading relationship with itself. A writing that seeks a jouissance of vacancy in tracking the spectrality of paper ghosts. The possibilities for transformation happen in chiasmatic passages from trope to performativity through re-readings and mis-readings. From a working text emerge articulations of a radical rhetoricity evoking ongoing labour from the para-sitic spatial punctuations of AuthorTextReader.
Rashba spin splitting in biased semiconductor quantum wells

description: Rashba spin splitting (RSS) in biased semiconductor quantum wells is investigated theoretically based on the eight-band envelope function model. We find that at large wave vectors, RSS is both nonmonotonic and anisotropic as a function of in-plane wave vector, in contrast to the widely used linear and isotropic model. We derive an analytical expression for RSS, which can correctly reproduce such nonmonotonic behavior at large wave vectors. We also investigate numerically the dependence of RSS on the various band parameters and find that RSS increases with decreasing band gap and subband index, increasing valence band offset, external electric field, and well width. Our analytical expression for RSS provides a satisfactory explanation to all these features.

description: The single index model (SIM), developed for analysis of financial assets, is assessed as a tool for evaluating the risk-return tradeoff faced in agricultural enterprise selection. This study tests whether some of the hypotheses underlying the SIM are valid when the SIM is used in agricultural cropping decisions. Empirical evidence from county level data does not support SIM hypotheses, indicating that more robust results might come from multiple index models.

description: We describe the transverse beam distribution in particle accelerators within the controlled, stochastic dynamical scheme of the Stochastic Mechanics (SM) which produces time reversal invariant diffusion processes. This leads to a linearized theory summarized in a Shchrödinger--like (\Sl) equation. The space charge effects have been introduced in a recent paper~\cite{prstab} by coupling this \Sl equation with the Maxwell equations. We analyze the space charge effects to understand how the dynamics produces the actual beam distributions, and in particular we show how the stationary, self--consistent solutions are related to the (external, and space--charge) potentials both when we suppose that the external field is harmonic (\emph{constant focusing}), and when we \emph{a priori} prescribe the shape of the stationary solution. We then proceed to discuss a few new ideas~\cite{epac04} by introducing the generalized Student distributions, namely non--Gaussian, Lévy \emph{infinitely divisible} (but not \emph{stable}) distributions. We will discuss this idea from two different standpoints: (a) first by supposing that the stationary distribution of our (Wiener powered) SM model is a Student distribution; (b) by supposing that our model is based on a (non--Gaussian) Lévy process whose increments are Student distributed. We show that in the case (a) the longer tails of the power decay of the Student laws, and in the case (b) the discontinuities of the Lévy--Student process can well account for the rare escape of particles from the beam core, and hence for the formation of a halo in intense beams.

On-chip TIRF nanoscopy by applying Haar wavelet kernel analysis on intensity fluctuations induced by chip illumination

description: Photonic-chip based TIRF illumination has been used to demonstrate several on-chip optical nanoscopy methods. The sample is illuminated by the evanescent field generated by the electromagnetic wave modes guided inside the optical waveguide. In addition to the photokinetics of the fluorophores, the waveguide modes can be further exploited for introducing controlled intensity fluctuations for exploitation by techniques such as super-resolution optical fluctuation imaging (SOFI). However, the problem of non-uniform illumination pattern generated by the modes contribute to artifacts in the reconstructed image. To alleviate this problem, we propose to perform Haar wavelet kernel (HAWK) analysis on the original image stack prior to the application of (SOFI). HAWK produces a computational image stack with higher spatio-temporal sparsity than the original stack. In the case of multimoded non-uniform illumination patterns, HAWK processing bre aks the mode pattern while introducing spatio-temporal sparsity, thereby differentially affecting the non-uniformity of the illumination. Consequently, this assists nanoscopy methods such as SOFI to better support super-resolution, which is otherwise compromised due to spatial correlation of the mode patterns in the raw image. Furthermore, applying HAWK prior to SOFI alleviates the problem of artifacts due to non-uniform illumination without degrading temporal resolution. Our experimental results demonstrate resolution enhancement as well as reduction in artifacts through the combination of HAWK and SOFI.

description: A new method for computing exact conformal partial wave expansions is developed and applied to approach the problem of Hilbert space (Wightman) positivity in a non-perturbative four-dimensional quantum field theory model. The model is based on the assumption of global conformal invariance on compactified Minkowski space. Bilocal fields arising in the harmonic decomposition of the operator product expansion prove to be a powerful instrument in exploring the field content. In particular, in the theory of a field of dimension 4 which has the properties of a (gauge invariant) Lagrangian, the scalar field contribution to the 6-point function of the twist 2 bilocal field is analyzed with the aim to separate the free field part from the nontrivial part.

description: We have performed an exclusive measurement of the $K^{-}+\! ~^{3}{\rm He} \to Λpn$ reaction at an incident kaon momentum of $1\ {\rm GeV}/c$.In the $Λp$ invariant mass spectrum, a clear peak was observed below the mass threshold of $\bar{K}\!+\!N\!+\!N$, as a signal of the kaonic nuclear bound state, $\bar{K}NN$.The binding energy, decay width, and $S$-wave Gaussian reaction form-factor of this state were observed to be $B_{K} = 42\pm3({\rm stat.})^{+3}_{-4}({\rm syst.})\ {\rm MeV}$, $Γ_{K} = 100\pm7({\rm stat.})^{+19}_{-9}({\rm syst.})\ {\rm MeV}$, and $Q_{K} = 383\pm11({\rm stat.})^{+4}_{-1}({\rm syst.})\ {\rm MeV}/c$, respectively. The total production cross-section of $\bar{K}NN$, determined by its $Λp$ decay mode, was $σ^{tot}_{K} \cdot BR_{Λp} = 9.3\pm0.8({\rm stat.})^{+1.4}_{-1.0}({\rm syst.})\ μ{\rm b}$.We estimated the branching ratio of the $\bar{K}NN$ state to the $Λp$ and $Σ^{0}p$ decay modes as $BR_{Λp}/BR_{Σ^{0}p} \sim 1.7$, by assuming that the physical processes leading to the $ΣN\!N$ final states are analogous to those of $Λpn$.

description: Secondary data and survey information are used to develop a large data set for analyzing water demand in 221 communities. The resulting monthly data are employed to examine seasonal variability in consumer price sensitivity. Several functional forms are contrasted for their abilities to identify monthly price elasticities. Results demonstrate the statistical contribution of a new climate variable for fitting monthly data, generally indicate that summer price elasticities exceed winter price elasticities by 30%, and appear to reject the use of the translog functional form as well traditional linear and Cobb-Douglas forms for statistical analyses of pooled monthly data. The generalized Cobb-Douglas and augmented Fourier forms are more viable alternatives for pooled monthly data.

description: The ESO Very Large Telescope Interferometer (VLTI) is one of the leading interferometric facilities. It is equipped with several 8.2 and 1.8m telescopes, a large number of baselines up to 200m, and with several subsystems designed to enable high quality measurements and to improve significantly the limits of sensitivities currently available to long-baseline interferometry. The full scientific potential of the VLTI can be exploited only if a consistent set of good quality calibrators is available. For this, a large number of observations of potential calibrators have been obtained during the commissioning phase of the VLTI. These data are publicly available. We briefly describe the interferometer, the VINCI instrument used for the observations, the data flow from acquisition to processed results, and we present and comment on the volume of observations gathered and scrutinized. The result is a list of 191 calibrator candidates, for which a total of 12066 observations can be deemed of satisfactory quality. We present a general statistical analysis of this sample, using as a starting point the angular diameters previously available in the literature.We derive the general characteristics of the VLTI transfer function, and its trend with time in the period 2001 through mid-2004. A second paper will be devoted to a detailed investigation of a selected sample, aimed at establishing a VLTI-based homogeneous system of calibrators.

description: The effects of price changes on irrigation technology transitions and potential agricultural water conservation in the Pacific Northwest are analyzed using Parks' (1980) modified multinomial logit model. Results indicate that commodity price effects are statistically significant, but they are relatively small with nonprogram crop price effects greater than program crop price effects. Locational factors are also found to affect technology transitions. In the absence of water policy changes, continued irrigation technology adoption by year 2005 will result in average annual water savings of approximately 404,000 acre-feet in the Pacific Northwest.

description: Graphics Interchange Format (GIF) is a widely used image file format. Due to the limited number of palette colors, GIF encoding often introduces color banding artifacts. Traditionally, dithering is applied to reduce color banding, but introducing dotted-pattern artifacts. To reduce artifacts and provide a better and more efficient GIF encoding, we introduce a differentiable GIF encoding pipeline, which includes three novel neural networks: PaletteNet, DitherNet, and BandingNet. Each of these three networks provides an important functionality within the GIF encoding pipeline. PaletteNet predicts a near-optimal color palette given an input image. DitherNet manipulates the input image to reduce color banding artifacts and provides an alternative to traditional dithering. Finally, BandingNet is designed to detect color banding, and provides a new perceptual loss specifically for GIF images. As far as we know, this is the first fully differentiable GIF encoding pipeline based on deep neural networks and compatible with existing GIF decoders. User study shows that our algorithm is better than Floyd-Steinberg based GIF encoding.
The Proper Motion of the Magellanic Clouds: The UCAC2-Hipparcos Inconsistency

description: Using the USNO CCD Astrograph all-sky Catalog (UCAC2), we measure the mean proper motion of the two Magellanic Clouds. Appropriately selected LMC populations show a proper motion (, ) ~ (+0.84,+4.32) that is significantly higher, in , than currently accepted Hipparcos-like values, , ~ (+1.94,-0.14). A higher value is also found for the SMC. Interestingly, the mean UCAC2 LMC proper motion agrees very well with the only work in the literature (Anguita et al. 2000) pointing to an unbound Magellanic Clouds-Milky Way interaction. Nonetheless, the implications of the UCAC2 proper motion are hard to reconcile with our present day understanding of the Clouds-Galaxy interaction unless one assumes a more massive Milky Way. Consequently, although no sources of systematic error have been identified, it is perhaps most likely that the UCAC2 catalog has an as yet unidentified systematic error resulting in an inconsistency between UCAC2 and Hipparcos based results for the Magellanic Clouds.

description: Technical progress in U.S. agriculture is evaluated using a new measure of productivity growth, flexible technical change. This measure allows for nonconstant returns to scale, market structures other than perfect competition, and time-varying coefficients. An integral part of the procedure is the estimation of the production function by Flexible Least Squares. Flexible technical change results are compared with two traditional measures of productivity growth and found to be more stable and more precise in a statistical sense. The results suggest that previous studies which employed total factor productivity measures may have overstated the impact of technology in agriculture.

description: This article proposes an oligopsony pricing model for projecting the effects of increased concentration or oligopsonistic coordination in beef packing using simulation methods. The model combines an explicit behavioral theory of packing firms with an attempt to respect the regional scope of cattle procurement markets. Our results indicate less danger of falling cattle prices, as a results of increase packer concentration or coordination, than do results from conventional econometric studies.

description: Observations of thermally driven transverse vibration of a photonic crystal waveguide (PCW) are reported. The PCW consists of two parallel nanobeams with a 240 nm vacuum gap between the beams. Models are developed and validated for the transduction of beam motion to phase and amplitude modulation of a weak optical probe propagating in a guided mode (GM) of the PCW for probe frequencies far from and near to the dielectric band edge. Since our PCW has been designed for near-field atom trapping, this research provides a foundation for evaluating possible deleterious effects of thermal motion on optical atomic traps near the surfaces of PCWs. Longer term goals are to achieve strong atom-mediated links between individual phonons of vibration and single photons propagating in the GMs of the PCW, thereby enabling opto-mechanics at the quantum level with atoms, photons, and phonons. The experiments and models reported here provide a basis for assessing such goals, including sensing mechanical motion at the Standard Quantum Limit (SQL).

description: Since nearly the entire U.S. output of agricultural commodities is produced by proprietors with limited liability, it is important to understand how limited liability affects decision in a risky environment. This article extends the work of Robinson and Barry; Robinson and Lev; and Robinson, Barry, and Burghart. It provides a rigorous derivation of one of their objective functions, compares it to standard risk analysis tools, and suggests several methods of empirical implementation. Under some conditions, utility maximization in the limited liability environment is consistent with optimization of Roy's safety-first criterion, while in other situations Freund's mean-variance criterion is appropriate. However, it is easy to demonstrate cases where neither criterion is applicable.

description: Whimsy in specification choices leads to fragility of inference in econometric studies of structural change in meat demand. The literature contains a variety of results, with many contradictions, attributable largely to differences in specifications. This article reviews that literature, uses synthetic data to demonstrate the sensitivity of results to specification choices and to evaluate the power of nonparametric tests, and uses Canadian data to demonstrate a preferred approach to testing the hypothesis of structural change.

description: The credit demand in the agriculture has remained low despite of the increase of credit access in this sector. Therefore, there is a demand problem that could be caused by low productivity and little returns. Some argue that these two factors could grow due to the productive associations. Motivated by understanding the economic behavior of the small farmers, this research seeks to estimate the impact of these organizations in credit demand. The group that will be analyzed is the small coffee producers in Peru. The propensity score matching is the econometric model that has been chosen to be used for analysis, and the data has been taken from the IV National Census of Agriculture. The results show that the small coffee farmers that are associated increase 2.21 times the odds of demanding credit compared to those with similar characteristics that are not associated. Consistent with the theory, productive associations have a positive, significant and causal effect in the credit demand of the small coffee farmers of Peru.

description: We derive a multi-band formulation of the orbital magnetization in a normal periodic insulator (i.e., one in which the Chern invariant, or in 2d the Chern number, vanishes). Following the approach used recently to develop the single-band formalism [T. Thonhauser, D. Ceresoli, D. Vanderbilt, and R. Resta, Phys. Rev. Lett. {\bf 95}, 137205 (2005)], we work in the Wannier representation and find that the magnetization is comprised of two contributions, an obvious one associated with the internal circulation of bulk-like Wannier functions in the interior and an unexpected one arising from net currents carried by Wannier functions near the surface. Unlike the single-band case, where each of these contributions is separately gauge-invariant, in the multi-band formulation only the \emph{sum} of both terms is gauge-invariant. Our final expression for the orbital magnetization can be rewritten as a bulk property in terms of Bloch functions, making it simple to implement in modern code packages. The reciprocal-space expression is evaluated for 2d model systems and the results are verified by comparing to the magnetization computed for finite samples cut from the bulk. Finally, while our formal proof is limited to normal insulators, we also present a heuristic extension to Chern insulators (having nonzero Chern invariant) and to metals. The validity of this extension is again tested by comparing to the magnetization of finite samples cut from the bulk for 2d model systems. We find excellent agreement, thus providing strong empirical evidence in favor of the validity of the heuristic formula.

description: In this paper the behavioural change framework of Ajzen and Fishbein is used to explore whether attitudes towards organic farming, the perceived social pressure of the environment and the perceived feasibility of organic farming standards on the farm determine the willingness of farmers to convert to organic farming methods. These variables together with the business and personal objectives and the organic farming information seeking behaviour of the farmer were used in an ordinal regression procedure to predict the intended organic farming conversion behaviour of conventional farmers.

description: According to the information perspectives of accounting, the main function of accounting is to provide information and to reduce uncertainty. Therefore, accounting capacity of reducing uncertainty determines the accounting quality (AQ) and so, we are attempting to find the best combinations of AQ Proxies whose trading off can reduce uncertainty. The purpose of this paper is to explore how AQ Proxies could reduce uncertainty. Tree analysis (structures of if and then) is employed since this analysis could empirically address boththe trade-off of Proxies and the importance of each measure in reducing uncertainty. Also, traditional statistics tests are employed. The Decision Tree analysis creates a tree-based classification model. Our findings suggest that there are at least three interaction paths through which accounting quality Proxies could reduce uncertainty. In contrast to previous researches which have found it difficult to investigate the trade-offs of AQ Proxies; this paper shows that it is possible to address it and in this way, it could prepare a number ofrules of thumb to reduce uncertainty through AQ Proxies. These findings have different implications for policy makers, audit committees, and investors.

description: In the recent years, the universities have been worried about performance management more than ever. In the present complex and competitive universe, the success of universities is impossible without presence of proper strategy and methods for evaluating their level of achievements. The balanced scorecard method is a model of evaluating performance and a system of strategic management. The main objective of present study is to determine the key measures of evaluating performance in association with learning and growth in Alzahra University. One of most common method of data collection also used in the present is questionnaire. In addition, the study of learning and growth strategies is done through balanced scorecard model, the statistical sampling is completed through t-test and the ranking of measures is done through Friedman test. Finally, the proper measures of learning and growth are extracted for the university. In addition, the strategy map and balanced scorecard are developed.

description: In this paper, we consider the inverse eigenvalue problem for the positive doubly stochastic matrices, which aims to construct a positive doubly stochastic matrix from the prescribed realizable spectral data. By using the real Schur decomposition, the inverse problem is written as a nonlinear matrix equation on a matrix product manifold. We propose monotone and nonmonotone Riemannian inexact Newton-CG methods for solving the nonlinear matrix equation. The global and quadratic convergence of the proposed methods is established under some assumptions. We also provide invariant subspaces of the constructed solution to the inverse problem based on the computed real Schur decomposition. Finally, we report some numerical tests, including an application in digraph, to illustrate the effectiveness of the proposed methods.

description: We study the static magnetic correlations in lightly doped La(2-x)Sr(x)CuO(4) within the framework of a dipolar frustration model for a canted antiferromagnet. We show that the stability of the canted Neel state for x<2% is due to the Dzyaloshinskii-Moriya and XY anisotropies. For higher doping the ground state is unstable towards a helicoidal magnetic phase where the transverse components of the staggered magnetization rotate in a plane perpendicular to the orthorhombic b-axis. Our theory reconciles, for the first time, the incommensurate peaks observed in elastic neutron scattering with Raman and magnetic susceptibility experiments in La(2-x)Sr(x)CuO(4).

description: There has been a decline in crop productivity in Kenya, a situation that has contributed to the raising food insecurity in the country. Communities in arid and semi-arid areas of the country, the landless, and female headed households are particularly vulnerable to food insecurity. Given the rising percentage of female headed households in Kenya (estimated at 37% in 2005), there is need to examine crop productivity in male and female managed farms and do a diagnosis of factors that lead to low productivity in female headed households and hence their higher vulnerability to food insecurity. This paper aims at examining gender differentials in farm resource ownership and how it affects the technical efficiency in maize production in male and female managed farms. The underlying hypothesis in this paper is that: given the same level of production technology, there should be no significant differences in the levels of maize productivity between male and female farmers. Hence, any significant differences would be attributed to differences in access to production resources. The paper focuses on maize since it is the staple crop in the study region and in Kenya. The stochastic frontier analysis reveals that both male and female managed farms are technically inefficient, since both categories of farm households produced below the production frontier. Contributing factors to the inefficiency were low levels of formal education, lack of access to credit and agriculture extension facilities, low input use and labour constraints especially in female farm households.
