The estimation of the degree of pricing competition in the British Columbia wine industry (1957-1986)
Creators: name: Adams, Derek
Publisher: name: University of British Columbia
Year: 2008

description: Until the introduction of the trade liberalization initiatives of 1989, the wine producers of British Columbia appeared to have operated in an environment that fostered less than competitive behaviour. Two factors in particular may have been responsible for creating such an environment: (1) the structure of the industry was inherently oligopolistic; and (2) protection from foreign competition was afforded by the British Columbia government in the form of a wine policy that effectively created non-tariff trade barriers against foreign wine producers. This study econometrically tests the hypothesis that British Columbia wine producers behaved non-competitively during the years 1957 to 1986. A model of the British Columbia wine industry is developed and used to estimate the degree of non-competitive pricing behaviour in the industry, and tests are undertaken to determine whether the estimate of behaviour is consistent with competitive or with other well known behavioral specifications. the main structural components of the industry are described in a model of oligopolistic behaviour using a linear system of equations, in which both demand and pricing equations appear. The parameters which affect each of these equations are estimated using the appropriate estimation technique. The econometric results, and the subsequent statistical tests, support the hypothesis that the domestic wine industry in British Columbia operated in a non-competitive manner between 1957 and 1986. Specifically, the hypothesis of competitive behaviour is statistically rejected, whereas, the hypotheses of Cournot and collusive-type behaviour could not be rejected. These results suggest that British Columbia consumers may have been sacrificing to firms at least a portion of the surplus they would have obtained in a perfectly competitive industry. In addition, it appears that the wine policy of the provincial government helped create a non-competitive industry that will likely have difficulty competing in today's global market for wine.

description: The magnetic dynamic structure factor of the one-dimensional S = 1/2 chain system BaCu2(Si0.5Ge0.5)2O7 is studied in a wide range of energy transfers and temperatures. Contrary to previous erroneous reports [T. Masuda et al., Phys. Rev. Lett. 93, 077206 (2004)], the scaling properties observed in the range 0.5-25 meV are found to be fully consistent with expectations for a Luttinger spin liquid. At higher energies, a breakdown of scaling laws is observed and attributed to lattice effects. The results are complementary to those found in literature for other S = 1/2-chain compounds, such as KCuF3 and Cu-benzoate.

Anomalous fractional quantization in the kagomelike Heisenberg ladder: Emergence of the effective spin-1 chain

description: We study a Kagome-like spin-$1/2$ Heisenberg ladder with competing ferromagnetic (FM) and antiferromagnetic (AFM) exchange interactions. Using the density-matrix renormalization group based calculations, we obtain the ground state phase diagram as a function of the ratio between the FM and AFM exchange interactions. Five different phases exist. Three of them are spin polarized phases; an FM phase and two kinds of ferrimagnetic (FR) phases (referred to as FR1 and FR2 phases). The spontaneous magnetization per site is $m=1/2$, $1/3$, and $1/6$ in the FM, FR1, and FR2 phases, respectively. This can be understood from the fact that an effective spin-1 Heisenberg chain formed by the upper and lower leg spins has a three-step fractional quantization of the magnetization per site as $m=1$, $1/2$, and $0$. In particular, an anomalous "intermediate" state $m=1/2$ of the effective spin-1 chain with the reduced Hilbert space of a spin from $3$ to $2$ dimensional is highly unexpected in the context of conventional spin-1 physics. Thus, surprisingly, the effective spin-1 chain behaves like a spin-1/2 chain with SU(2) symmetry. The remaining two phases are spin-singlet phases with translational symmetry breaking in the presence of valence bond formations. One of them is octamer-siglet phase with a spontaneous octamerization long-range order of the system, and the other is period-4 phase characterized by the magnetic superstructure with a period of four structural unit cells. In these spin-singlet phases, we find the coexistence of valence bond structure and gapless chain. Although this may be emerged through the order-by-disorder mechanism, there can be few examples of such a coexistence.

description: The application of the equivalent static method for the seismic design of asymmetric multi-storey buildings presupposes the existence of a vertical elastic axis – the geometrical locus of the elastic centres of the floors- so as to identify the eccentricity of the static seismic loads. But, while in single-storey buildings the elastic centre is always defined and has determined static properties, in multi-storey buildings they said properties are not, in general, identified and the definition of the elastic axis is, in general, impossible. In this work, we first proceed to the analysis of the cases of existence of non-existence of an elastic axis and of building’s principal bending vertical planes, according to research data of the last ten years. Following this stage, and based on the building’s “optimum torsion” criterion, a fictitious elastic axis is defined for every case of a regular in elevation building using the continuous model of the structure. The same results verified by the discrete model of the structure. This axis may play the same role as the real vertical elastic axis during the application of the equivalent static method.

description: The insulator/metal transition induced by hole-doping due to neodymium vacancies of the Mott- Hubbard antiferromagnetic insulator, Nd1-xTiO3, is studied over the composition range 0.010(6) < x < 0.243(10). Insulating p-types conduction is found for x < 0.071(10). Anderson localization in the presence of a Mott-Hubbard gap, is the dominant localization mechanism for the range of 0.074(10) < x < 0.089(1) samples. For x < 0.089(1), n-type conduction is observed and the activation energy extrapolates to zero by x < 0.1. The 0.095(8) < x < 0.203(10) samples are Fermi-liquid metals and the effects of strong electronic correlations are evident near the metal-to-insulator boundaries in features such as large Fermi liquid T2 coefficients. For 0.074(9) < x < 0.112(4), a weak negative magnetoresistance is found below ~ 15 K and it is attributed to the interaction of conduction electrons with Nd3+ magnetic moments. Combining information from our companion study of the magnetic properties of Nd1-xTiO3 solid solution, a phase diagram is proposed. The main conclusions are that long range antiferromagnetic order disappears before the onset of metallic behavior and that the Anderson-Mott transition occurs over a finite range of doping levels. Our results differ from conclusions drawn from a similar study on the hole doped Nd1-xCaxTiO3 system which found the co-existence of antiferromagnetic order and metallic behavior and that the Mott transition occurs at a discrete doping level.

description: We present a new, fast, and easy to use tool for modelling light and radial velocity curves of close eclipsing binaries with built-in methods for solving an inverse problem. The main goal of ELISa (Eclipsing binary Learning and Interactive System) is to provide an acceptable compromise between computational speed and precision during the fitting of light curves and radial velocities of eclipsing binaries. The package is entirely written in the Python programming language in a modular fashion, making it easy to install, modify, and run on various operating systems. ELISa implements Roche geometry and the triangulation process to model a surface of the eclipsing binary components, where the surface parameters of each surface element are treated separately. Surface symmetries and approximations based on the similarity between surface geometries were used to reduce the runtime during light curve calculation significantly. ELISa implements the least square trust region reflective algorithm and Markov-chain Monte Carlo optimisation methods to provide the built-in capability to determine parameters of the binary system from photometric observations and radial velocities. The precision and speed of the light curve generator were evaluated using various benchmarks. We conclude that ELISa maintains an acceptable level of accuracy to analyse data from ground-based and space-based observations, and it provides a significant reduction in computational time compared to the current widely used tools for modelling eclipsing binaries.

The enhancement is partially attributed to the Purcell effect. Purcell factor predicted by FDTD calculations is 32 for a linear three-defect cavity mode with computed quality factor of 332 and mode volume of 0.785 cubic wavelengths. Experimentally measured cavity quality (Q) factors vary in the range of 200 to 300, showing excellent agreement with calculations. The emission peak can be tuned to any wavelength in the 600 to 800 nm range.

Production and preliminary characterization of a fusion protein comprising streptavidin and a cellulose-binding domain
Creators: name: Le, Duy Khai
Publisher: name: University of British Columbia
Year: 2008

description: The cellulose-binding domain of exoglucanase Cex (CBDCex) from Cellulomonas fimi can be fused to heterologous proteins. The fusion proteins can be purified by affinity chromatography on cellulose or immobilized on cellulose (Ong et al., 1989b). Streptavidin, a protein produced by Streptomyces avidinii, binds to the water-soluble vitamin, D-biotin, with remarkably high affinity. The strong and specific biotin-binding affinity of streptavidin offers a variety of applications in biotechnology (Wilchek and Bayer, 1990). The streptavidin gene was fused in frame to the CBDcex coding sequence and the gene fusion expressed to give a chimeric protein comprising streptavidin and the cellulose-binding domain. The fusion protein was overexpresed in E. coli and formed inclusion bodies. The soluble renatured protein recovered from the inclusion bodies bound both biotin and cellulose. It could be used to bind biotinylated proteins to cellulose.
A most compendious and facile quantum de Finetti theorem

description: In its most basic form, the finite quantum de Finetti theorem states that the reduced k-partite density operator of an n-partite symmetric state can be approximated by a convex combination of k-fold product states. Variations of this result include Renner's "exponential" approximation by "almost-product" states, a theorem which deals with certain triples of representations of the unitary group, and D'Cruz et al.'s result for infinite-dimensional systems. We show how these theorems follow from a single, general de Finetti theorem for representations of symmetry groups, each instance corresponding to a particular choice of symmetry group and representation of that group. This gives some insight into the nature of the set of approximating states, and leads to some new results, including an exponential theorem for infinite-dimensional systems.

description: Dust particle impacts on the Wind spacecraft were detected with its plasma wave instrument Wind/WAVES. Frequency analysis on this dust impact time series revealed spectral peaks indicative of a solar rotation signature. We investigated whether this solar rotation signature is embedded in the interplanetary or interstellar dust (ISD) and whether it is caused by co-rotating interaction regions (CIRs), by the sector structure of the interplanetary magnetic field (IMF), or by external effects. We performed frequency analysis on subsets of the data to investigate the origin of these spectral peaks, comparing segments of Wind's orbit when the spacecraft moved against or with the ISD inflow direction and comparing the time periods of the ISD focusing and defocusing phases of the solar magnetic cycle. A superposed epoch analysis of the number of dust impacts during CIRs was used to investigate the systematic effect of CIRs. Case studies of time periods with frequent or infrequent occurrences of CIRs were compared to synthetic data of dust impacts affected by CIRs. We performed similar case studies for time periods with a stable or chaotic IMF sector structure. The superposed epoch analysis was repeated for a time series of the spacecraft floating potential. Spectral peaks were found at the solar rotation period of ~27d and its harmonics at 13.5d and 9d. This solar rotation signature may affect both interplanetary and ISD. The appearance of this signature correlates with the occurrence of CIRs but not with the stability of the IMF sector structure. The CIRs cause, on average, a reduction in the number of dust impact detections. Periodic changes of the spacecraft's floating potential were found to partially counteract this reduction by enhancing the instrument's sensitivity to dust impacts; these changes of the floating potential are thus unlikely to be the cause of the solar rotation signature.

description: In this paper, we propose a new technique that applies automated image analysis in the area of structural corrosion monitoring and demonstrate improved efficacy compared to existing approaches. Structural corrosion monitoring is the initial step of the risk-based maintenance philosophy and depends on an engineer's assessment regarding the risk of building failure balanced against the fiscal cost of maintenance. This introduces the opportunity for human error which is further complicated when restricted to assessment using drone captured images for those areas not reachable by humans due to many background noises. The importance of this problem has promoted an active research community aiming to support the engineer through the use of artificial intelligence (AI) image analysis for corrosion detection. In this paper, we advance this area of research with the development of a framework, CorrDetector. CorrDetector uses a novel ensemble deep learning approach underpinned by convolutional neural networks (CNNs) for structural identification and corrosion feature extraction. We provide an empirical evaluation using real-world images of a complicated structure (e.g. telecommunication tower) captured by drones, a typical scenario for engineers. Our study demonstrates that the ensemble approach of \model significantly outperforms the state-of-the-art in terms of classification accuracy.

description: Two exact lens equations have been recently shown to be equivalent to each other, being consistent with the gravitational deflection angle of light from a source to an observer, both of which can be within a finite distance from a lens object [Phys. Rev. D 102, 064060 (2020)]. We examine methods for iterative solutions of the gravitational lens equations in the strong deflection limit. It has been so far unclear whether a convergent series expansion can be provided by the gravitational lens approach based on the geometrical optics for obtaining approximate solutions in the strong deflection limit in terms of a small offset angle. By using the ratio of the lens mass to the lens distance, we discuss a slightly different method for iterative solutions and the behavior of the convergence. Finite distance effects begin at the third order in the iterative method. The iterative solutions in the strong deflection limit are estimated for Sgr $A^{*}$ and M87. These results suggest that only the linear order solution can be relevant with current observations, while the finite distance effects at the third order may be negligible in the Schwarzschild lens model for these astronomical objects.

description: Despite their dispersion-less character, flat bands (FBs) are often at the heart of remarkable physical phenomena. Because, FBs may be responsible for unconventional quantum electronic transport, our purpose is to investigate their impact on the RKKY couplings (J(R)). As a good candidate, we choose the The Lieb lattice which consists of one four-fold coordinated atom (A) and two two-fold coordinated atoms (B,C) per unit cell. As in graphene, at the neutrality point, J(R) is found to fall off as 1/R3. The coupling between a pair of impurities on sublattice A are found ferromagnetic and isotropic. In contrast, for impurities on the two-fold coordinated sites, J(R) reveals (i) a strong angular anisotropy and (ii) can be both ferromagnetic (F) or antiferromagnetic (AF). The AF character introduced by the FB can largely dominate, and introduces frustration effects. The FB is found to have a drastic impact on J(R) for impurities located on (B,C) sublattices. We have also addressed the effect of tuning the carrier density that reveals remarkable features as well.

description: The magnon-magnon coupling in synthetic antiferromagnets advances it as hybrid magnonic systems to explore the quantum information technologies. To induce the magnon-magnon coupling, the parity symmetry between two magnetization needs to be broken. Here we experimentally demonstrate a convenient method to break the parity symmetry by the asymmetric thickness of two magnetic layers and thus introduce a magnon-magnon coupling in Ir-based synthetic antiferromagnets CoFeB(10 nm)/Ir(tIr=0.6 nm, 1.2 nm)/CoFeB(13 nm). Remarkably, we find that the weakly uniaxial anisotropy field (~ 20 Oe) makes the magnon-magnon coupling anisotropic. The coupling strength presented by a characteristic anticrossing gap varies in the range between 0.54 GHz and 0.90 GHz for tIr =0.6 nm, and between nearly zero to 1.4 GHz for tIr = 1.2 nm, respectively. Our results demonstrate a feasible way to induce the magnon-magnon coupling by an asymmetric structure and tune the coupling strength by varying the direction of in-plane magnetic field. The magnon-magnon coupling in this highly tunable material system could open exciting perspectives for exploring quantum-mechanical coupling phenomena.

Stepwise temperature behavior of the susceptibility of the single crystal sample and corresponding singular behavior of the internal friction in the polycrystalline manganite have been found. These small-scale features of the temperature dependences of the susceptibility and the internal friction are considered to be a reflection of martensitic kinetics of the structural phase transformation R3c-Imma in the 200 K temperature region.

description: The minimal extension of the scalar sector of the standard model contains an additional real scalar field with no gauge quantum numbers. Such a field does not couple to the quarks and leptons directly but rather through its mixing with the standard model Higgs field. We examine the phenomenology of this model focusing on the region of parameter space where the new scalar particle is significantly lighter than the usual Higgs scalar and has small mixing with it. In this region of parameter space most of the properties of the additional scalar particle are independent of the details of the scalar potential. Furthermore the properties of the scalar that is mostly the standard model Higgs can be drastically modified since its dominant branching ratio may be to a pair of the new lighter scalars.

description: Background: Having a child with Autism Spectrum Disorder can affect family wellbeing and caregiver’s parenting skills. The present review aims to explore the main difficulties reported by parents of children with autism and the most used interventions to provide them support to date. Methods: 26 research articles published from 2006 to 2019 were selected and compared, specifically 10 quantitative and 16 qualitative studies, in which the following topics were discussed: parental stress in the presence of autism, presence of guidelines for intervention and relative difficulties to the achievement of the diagnosis. Results: The results of the review analysis indicate that parental stress is one of the difficulties in assuming a primary role. Parents caring for a child with Autism Spectrum Disorder have been shown to experience significantly higher levels of stress than parents of typically developing children. Conclusions: The presence of guidelines and the difficulties in achieving a diagnosis are closely related to the issue of parental stress, increasing or decreasing the perceived stress of parents.

Half-BPS SU(N) Correlators in N=4 SYM
Creators: name: Brown, T. W.
Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this note we study half-BPS operators in N=4 super Yang-Mills for gauge group SU(N) at finite N. In particular we elaborate on the results of hep-th/0410236, providing an exact formula for the null basis operators algorithmically constructed there. For gauge groups U(N) and SU(N) we show that this basis is dual to the basis of multi-trace operators with respect to the two point function. We use this to extend the results of hep-th/0611290 concerning factorisation and probabilities from U(N) to SU(N). We also give a construction for a separate diagonal basis of the SU(N) operators in terms of the higher Hamiltonians of the complex matrix model reduction of this sector.

description: SARS-CoV-2 mutants carrying the $Δ$H69/$Δ$V70 deletion in the amino terminal domain of the Spike protein emerged independently in at least six lineages of the virus (namely, B.1.1.7, B.1.1.298, B.1.160, B.1.177, B.1.258, B.1.375). Routine RT-qPCR tests including TaqPath or similar assays based on a drop-out of the Spike gene target are incapable of distinguishing among these lineages and often lead to the false conclusion that clinical samples contain the B.1.1.7 variant, which recently emerged in the United Kingdom and is quickly spreading through the human population. We analyzed SARS-CoV-2 samples collected from various regions of Slovakia between November and December 2020 that were presumed to contain the B.1.1.7 variant due to traveling history of the virus carriers or their contacts. Sequencing of these isolates revealed that although in some cases the samples were indeed confirmed as B.1.1.7, a substantial fraction of isolates contained another $Δ$H69/$Δ$V70 carrying mutant belonging to the lineage B.1.258, which has been circulating in Central Europe since August 2020, long before the import of B.1.1.7. Phylogenetic analysis shows that the early sublineage of B.1.258 acquired the N439K substitution in the receptor binding domain (RBD) of the Spike protein and, later on, also the deletion $Δ$H69/$Δ$V70 in the Spike N-terminal domain (NTD). This variant is particularly common in several European countries including Czech Republic and Slovakia, and we propose to name it B.1.258$Δ$.

description: We present spectroscopic observations with the 3.6m ESO telescope of two emission-line galaxies, J2104-0035 and J0113+0052, selected from the Data Release 4 (DR4) of the Sloan Digital Sky Survey (SDSS). From our data we determine the oxygen abundance of these systems to be respectively 12+logO/H = 7.26+/-0.03 and 7.17+/-0.09, making them the two most metal-deficient galaxies found thus far in the SDSS and placing them among the five most metal-deficient emission-line galaxies ever discovered. Their oxygen abundances are close to those of the two most metal-deficient emission-line galaxies known, SBS0335-052W with 12+logO/H = 7.12+/-0.03 and I Zw 18 with 12+logO/H = 7.17+/-0.01.

Italian Standardization of teacher and parent screenings for Identifying Gifted and Talented Children aged from 6 to 13
Creators: name: Fabio, Rosa Angela
Publisher: name: Journal of Clinical & Developmental Psychology
Year: 2019

description: The present standardization study is based on a published paper titled “Identifying Giftedness: Validation of an Italian Language Giftedness Checklist for Teachers and Parents” by Fabio and Buzzai (2019). The purpose of the present study is to show the Italian Adaptation of the Giftedness Checklist of Sommer, Fink and Neubauer (2008), in both the versions for teachers and parents. The present screening can help to cope with multidimensional definitions of giftedness, and to cope also with the usefulness of information provided by parents and teachers. More in depth, the specific aims are: 1) to show an easy administration of the screening test for identifying of gifted and talented children aged from 6 to 13; 2) to show how to sum the scores obtained and 3) to indicate how to easily compare them with z-scores. Italian language screening and scoring rules are presented in the tables 1, 2, 3 and 4.

To H0 or not to H0?

Publisher: name: arXiv
Year: 2021
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: This paper investigates whether changes to late time physics can resolve the `Hubble tension'. It is argued that many of the claims in the literature favouring such solutions are caused by a misunderstanding of how distance ladder measurements actually work and, in particular, by the inappropriate use of a distance ladder H0 prior. A dynamics-free inverse distance ladder shows that changes to late time physics are strongly constrained observationally and cannot resolve the discrepancy between the SH0ES data and the base LCDM cosmology inferred from Planck. We propose a statistically rigorous scheme to replace the use of H0 priors

Marketing cooperatives : A model of the output decisions of the Cloverdale lettuce and vegetable cooperative
Creators: name: Latham, Susie
Publisher: name: University of British Columbia
Year: 2008

description: Marketing cooperatives play an important role in agricultural activities. Institutional support for cooperatives is based on the idea that, collectively, farmers can achieve benefits than, individually would be difficult to obtain. Head lettuce in the Lower Mainland region of British Columbia is marketed and distributed by a central selling agency which is organized as a producer cooperative. Members of the cooperative are subject to regulations, in the form of market quota allocations which control the quantity of head lettuce they can sell through their cooperative. This study describes and analyses the market structure of the head lettuce industry in British Columbia to ascertain and quantify the source of benefits to producers from cooperative marketing within a regulated marketing environment. A model of the industry is constructed to characterize the market for head lettuce in B.C. The parameters which affect consumer demand and farm supply are estimated with econometric equations. A feature of supply is that current production decisions are influenced by the producer's market quota allocation which, in turn, is determined by the producer’s past sales. The market quotas are believed to have constrained supply response and this is borne out by the empirical results which indicates a highly inelastic supply curve. The demand for head lettuce is also estimated to be inelastic. This result is not surprising since head lettuce is regarded as a basic commodity by consumers. The estimated supply and demand elasticities are used to derive linear supply and demand curves at the cooperative and wholesale levels. These are used with the observed 1990 price and quantity levels to calibrate a model of the B.C. head lettuce industry. A counterfactual model is then formulated to simulate a market with no controls on output. Given an inelastic wholesale demand, the simulation results indicate that for very small increases in cooperative output, large decreases in price occur. Consequently total revenues decline at every alternative assumption of supply increase. This result supports the hypothesis that output restrictions by the cooperative have the potential to increase members' output prices. It is concluded that while the market quotas have in the past provided positive benefits to cooperative members, the quotas may now be hindering the process of adjustment to the loss of tariff protection and changing market conditions by making producers less price responsive.

description: Holonomy groups and holonomy algebras for connections on locally free sheaves over supermanifolds are introduced. A one-to-one correspondence between parallel sections and holonomy-invariant vectors, and a one-to-one correspondence between parallel locally direct subsheaves and holonomy-invariant vector supersubspaces are obtained. As the special case, the holonomy of linear connections on supermanifolds is studied. Examples of parallel geometric structures on supermanifolds and the corresponding holonomies are given. For Riemannian supermanifolds an analog of the Wu theorem is proved. Berger superalgebras are defined and their examples are given.

description: We arrive at last number of 2019, and I introduce the topics of the number 3, vol 1. The focus of this scientific journal concerns fields of clinical psychology and health, in the life cycle. The issue concerns the acquisition of knowledge on methods and techniques of clinical and developmental psychology, with particular reference to childhood and school learning contexts with gifted child, to the parent-child educational relationship, the burden of the caregiver with children with mental illness, emotional dysregulation in the most widespread clinical area of mental health, such as addiction. The value of this number lies in the importance of update of research, in the psychological fields of the life cycle, in clinical and hospital settings, and institutions of care which contribute to the processes of humanization of public services.

Induction programs for beginning teachers : making a difference
Creators: name: Lim, Wendy Ann
Publisher: name: University of British Columbia
Year: 2008

description: This study was based on the experiences of six first year teachers in a District sponsored induction program. The purpose of the study is two-fold: to gain some insights into the perceptions of beginning teachers (in terms of their perceived concerns, level of support and dilemmas encountered), and to determine the impact of the induction program on their first year teaching experiences. It is hoped that the results of this study will help school districts design more effective induction programs to support beginning teachers as they make the transition from a university-based preparation program to full-time employment in the schools. Data were collected through focussed, semi-structured interviews. Over the duration of the year, four interviews were conducted with each first year teacher. The interviews were audiotaped and then transcribed verbatim. Through analysis of the transcripts, common perceptions were identified which captured some of the issues and concerns that they experienced in their first year of teaching. The findings of this study lead to the general conclusion that beginning teachers experience difficulties in their first year of teaching and that these difficulties are "dilemmas" that appear to be endemic to teaching. In addition, the findings identify some specific support components of induction programs that are helpful in assisting beginning teachers survive their first year of teaching. Finally, the findings lead to a general conclusion that induction success is very much dependent on the context of each beginning teacher, specifically the characteristics of the beginning teacher, the context of the teaching situation, and the support available for that beginning teacher.
A mean field approach for string condensed states

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We describe a mean field technique for quantum string (or dimer) models. Unlike traditional mean field approaches, the method is general enough to include string condensed phases in addition to the usual symmetry breaking phases. Thus, it can be used to study phases and phases transitions beyond Landau's symmetry breaking paradigm. We demonstrate the technique with a simple example: the spin-1 XXZ model on the Kagome lattice. The mean field calculation predicts a number of phases and phase transitions, including a z=2 deconfined quantum critical point.
