Coaching and peer-collaboration as a means for improving teaching: action research in an international school in Serbia
Creators: name: Malinic, Svetlana Belic
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: My research interest emerges from my observation that teachers in the international school in Serbia, where I worked during the research, seemed to be alienated in their classrooms and resistant to change agents. I, therefore, wanted to find out how coaching and peer-collaboration might affect teachers’ beliefs about their classroom practice, values they cherish about teaching, new knowledge constructed through collaboration and emerging attitudes towards reinvented pedagogies.Having applied a mixed method approach, I gathered two sets of comparable data: quantitative data, collected through the Questionnaire of Teacher Interaction (QTI), and qualitative data, generated from the coaching sessions. Once interpreted using thematic analysis, these sets produced teachers’ profiles as well as three themes: (1) resistance to change and reconciliation, (2) reflection about teaching, and (3) collaborative teaching through peer-collaboration. The findings showed how coaching and peer-collaboration situate in the context depending on the teachers’ career age, their openness to reculturing and preparedness to adapt to international education requirements. Finally, this study illuminates how the changes, which coaching and peer-collaboration bring about, take distinctive yet interdependent forms: (1) changes in the self, related to the innermost processes of the teachers, their personality traits and core values; (2) changes in the classroom, that is in the pedagogical practice and instructional designs with the students; (3) changes in communication within a school, not only with the students and other teachers, but also with the parents; (4) change in professional lives, which concern teachers’ understanding of their immediate context, collaborative culture and learning community.This research resulted in a process of reculturing of the school as an institution (Fullan, 1999), which allowed the teachers to voice their most pressing concerns, examine prior knowledge in the light of new understandings and construct new knowledge through processes of reflection, dialogue and enquiry (McCormack et al., 2006).

description: $^{139}$La- and $^{55}$Mn-NMR spectra demonstrate that the ground state of the A-site ordered perovskite manganite LaBaMn$_2$O$_6$ is a spatial mixture of the ferromagnetic (FM) and antiferromagnetic (AFI(CE)) regions, which are assigned to the metallic and the insulating charge ordered state, respectively. This exotic coexisting state appears below 200 K via a first-order-like formation of the AFI(CE) state inside the FM one. Mn spin-spin relaxation rate indicates that the FM region coexisting with the AFI(CE) one in LaBaMn$_2$O$_6$ is identical to the bulk FM phase of the disordered form La$_{0.5}$Ba$_{0.5}$MnO$_3$ in spite of the absence of A-site disorder. This suggests mesoscopic rather than nanoscopic nature of FM region in LaBaMn$_2$O$_6$\@.

description: Buyer competition in the price discovery process for slaughter lambs at an Oklahoma teleauction was studied. Number of buyers positively influenced both absolute and relative sale prices but did not significantly affect buyer gross margins. Buyer market shares also affected prices paid and buyer gross margins. Thus, competition among buyers was found to be important in the price discovery process.
title: Shaking Off the Rust: Unraveling the Depositional and Diagenetic History of Enigmatic Ferroan Dolostones in the Cambrian Bright Angel Formation, Tonto Group, Grand Canyon
Creators: name: Clevenger, Joseph J.
Publisher: name: Utah State University

description: Within the siliciclastic-sediment-dominated Bright Angel Formation (BAF) of the iconic Cambrian sedimentary strata (Tonto Group) in Grand Canyon National Park, Arizona, workers have identified and named prominent reddish-brown cliffs breaking up the generally slope-forming unit near, but separated from, its upper contact with the limestone-dominated Muav Formation, the "Rusty Brown Dolostones" (RBDs). Previous hypotheses suggest that the RBDs are chemically and physically altered tongues of the Muav Formation intercalated with the BAF at increasingly higher stratigraphic positions from west to east within the Canyon. A genetic association between the Muav Formation and the RBDs, as well as between the RBDs themselves, has yet to be established. Further, the paleoenvironment that these apparent couplets represent is poorly constrained. Understanding the formation and evolution of these deposits will fill a gap in our understanding that sits at a prominent transition in facies belts and thus depositional environments, elucidating processes that link two distinct belts of rock formed on the Cambrian Laurentian margin during a period of gradual sea level rise (termed the Sauk Transgression).
Here we use sedimentological observations and stratigraphic relationships to interpret the paleoenvironmental conditions that resulted in the deposition of the RBDs and provide a single more widely applicable definition of the member. We define the RBDs as sets of coupled repeating depositional cycles composed of subtidal marine shales, siltstones, and well-sorted fine-grained, glauconitic quartz arenites (sandstones). These packages transition upwards into iron enriched carbonates that span a genetic spectrum from apparently abiotic, to biotically-influenced, to biotically-mediated. These are interpreted as lagoonal to estuarine deposits influenced by tides, formed in a peritidal to shallow subtidal zone, and punctuated by storms that transition upsection into landward tongues of the Muav Formation developed during rising relative sea level. These sequences are subsequently overlain by BAF siliciclastic suites that advance seaward following the cessation of relative sea level rise. Sedimentological and geochemical analyses indicate a lack of subaerial exposure prior to burial and derivation of the ions necessary to transition these limestones into dolostones enriched in iron from the clay/mica mineral glauconite during shallow to intermediate burial alteration processes.

description: Recent and upcoming stabilized spectrographs are pushing the frontier for Doppler spectroscopy to detect and characterize low-mass planets. Specifications for these instruments are so impressive that intrinsic stellar variability is expected to limit their Doppler precision for most target stars (Fischer et al. 2016). To realize their full potential, astronomers must develop new strategies for distinguishing true Doppler shifts from intrinsic stellar variability. Stellar variability due to star spots, faculae and other rotationally-linked variability are particularly concerning, as the stellar rotation period is often included in the range of potential planet orbital periods. To robustly detect and accurately characterize low-mass planets via Doppler planet surveys, the exoplanet community must develop statistical models capable of jointly modeling planetary perturbations and intrinsic stellar variability. Towards this effort, this note presents simulations of extremely high resolution, solar-like spectra created with SOAP 2.0 (arXiv:1409.3594) that includes multiple evolving star spots. We anticipate this data set will contribute to future studies developing, testing, and comparing statistical methods for measuring physical radial velocities amid contamination by stellar variability.

Cyclosporine A improves coronary artery function in rat cardiac allografts

description: BACKGROUND: A marked decline in the vascular myogenic response during the course of allograft rejection was previously shown in a rat model of heart transplantation. Two important contributory features are an iNOS-catalyzed, NO-mediated vasodilation and a loss of smooth muscle function. In this study, the effect of cyclosporine A immunosuppressive therapy on the alleviation of myogenic and endothelial cell dysfunction of coronary resistance arteries in allograft was examined using pressure myography. We hypothesized that cyclosporine therapy will improve coronary artery function in rat cardiac allografts. METHODS: Coronary septal arteries (internal diameter 200μm) were dissected from heterotopic abdominal heart isografts (Lewis-Lewis) and allografts (Fisher-Lewis) at days 4 and 21 post-transplantation and mounted on a pressure myograph. Pressureinduced vasoconstriction was measured in the absence and presence of an iNOS blocker (aminoguanidine [AG], 100 μM). Endothelium based (ACh induced) and endothelium independent (SNP induced) vasorelaxation was also tested in each group and compared. RESULTS: Myogenic response was reduced in allograft coronary arteries at day 21 posttransplantation in comparison with matched isografts (p<0.05). AG potentiated myogenic tone in allograft arteries but had no effect on untreated day-21 isografts indicating the presence of iNOS based relaxation only in allograft vessels. At day 4, however, myogenic tone was potentiated by AG in all CsA-treated groups suggesting that CsA might induce iNOS in these vessels. Depolarization-induced vasoconstriction was lower in day-21 allografts in comparison to isografts whereas at day 4, KC1 induced tone was similar in both groups. CsA therapy also improved depolarization-induced constriction in day-21 allografts as compared to the other untreated groups (p<0.05). Furthermore, CsA therapy improved endothelium based and endothelium independent vasorelaxation in allograft arteries at day-21 post-transplantation. CONCLUSIONS: The results of this study suggest that CsA immunosuppressive therapy has a significant effect in the alleviation of early endothelial and smooth muscle cell dysfunction in coronary allograft vascular disease. However, the results reflect a dual and counterbalancing effect of CsA, both increasing the activity of iNOS (reducing tone) at an early time point, while attenuating the extent of smooth muscle destruction at a later time point (augmenting tone).

description: We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensional ferromagnetic Ising/Potts models. We first show that flat-histogram Monte Carlo methods with single-spin flip updates such as the Wang-Landau algorithm or the multicanonical method perform sub-optimally in comparison to an unbiased Markovian random walk in energy space. For the d=1,2,3 Ising model, the mean first-passage time τscales with the number of spins N=L^d as τ\propto N^2L^z. The critical exponent z is found to decrease as the dimensionality d is increased. In the mean-field limit of infinite dimensions we find that z vanishes up to logarithmic corrections. We then demonstrate how the slowdown characterized by z>0 for finite d can be overcome by two complementary approaches - cluster dynamics in connection with Wang-Landau sampling and the recently developed ensemble optimization technique. Both approaches are found to improve the random walk in energy space so that τ\propto N^2 up to logarithmic corrections for the d=1 and d=2 Ising model.

description: Using theoretical derivations, it is shown that collecting data on individuals' visitation rates to a recreation site by each of these methods: (1) on-site sampling of visits; (2) sampling individuals surrounding the recreations site; and (3) sampling license holders, results in three unique heteroskedacity problems. A different weighted least squares approach is offered in each case when estimating the visits per capita-travel cost relationship in zonal travel cost models. Furthermore, to the extent that individuals within an origin zone face different prices, there is an inherent aggregation bias when estimating consumer surplus.

description: This item accompanies the collection documenting it is impossible for everyone to achieve everything they want (2018), and is included as contextualising information.
Abstract:Scores that require participants to negotiate inter-personal relationships during performance encourage the development of individual and collective strategies for decision-making as part of the performance practice. Such strategies might be codified through rules specified in the score or developed more informally through the preferences of the performers. In both cases, models drawn from decision-making theory can be usefully applied to help explain the ways in which composers initiate these processes and how performers respond to them. In particular, heuristics suggest possible explanations for the ways in which such pieces operate in practice. A heuristic is a useful decision-making strategy that “ignores part of the information, with the goal of making decisions more quickly, frugally, and/or accurately than more complex methods” (Gigerenzer & Gaissmaier, 2011, p. 454). By reducing the amount of information to be considered, there is a corresponding reduction in the cognitive effort required to make a decision. This paper considers the creative potential for heuristics as a compositional strategy. It explores implicit uses of heuristics in work by Christian Wolff and Joseph Kudirka, as well as my own recent music. It examines how performer decisions in such pieces create different modes of interaction between individuals and rules. The practice presented in the paper provides possible models for embodying heuristics, and decision-making theories more generally, as a compositional strategy. I contend that defined heuristics are present in existing compositions where performers are required to make judgments based on available information, and that composers have deployed such heuristics intuitively. By making links between current heuristics theory and compositional practice, as well as showing how such theory might actively inform the creation of new work, the paper suggests future possibilities for creative practice.

description: In this paper the conditions for identifiability, separability and uniqueness of linear complex valued independent component analysis (ICA) models are established. These results extend the well-known conditions for solving real-valued ICA problems to complex-valued models. Relevant properties of complex random vectors are described in order to extend the Darmois-Skitovich theorem for complex-valued models. This theorem is used to construct a proof of a theorem for each of the above ICA model concepts. Both circular and noncircular complex random vectors are covered. Examples clarifying the above concepts are presented.

E 65, 036101 (2002)], we show that the realization of the thermostatistics of q-deformed algebra can be built on the formalism of q-calculus. It is found that the entire structure of thermodynamics is preserved if we use an appropriate Jackson derivative instead of the ordinary thermodynamic derivative. Furthermore, in analogy with the quantum q-oscillator algebra, we also investigate a possible q-deformation of the classical Poisson bracket in order to extend a generalized q-deformed dynamics in the classical regime.

description: This paper presents GPU performance optimization and scaling results for inference models of the Sparse Deep Neural Network Challenge 2020. Demands for network quality have increased rapidly, pushing the size and thus the memory requirements of many neural networks beyond the capacity of available accelerators. Sparse deep neural networks (SpDNN) have shown promise for reining in the memory footprint of large neural networks. However, there is room for improvement in implementing SpDNN operations on GPUs. This work presents optimized sparse matrix multiplication kernels fused with the ReLU function. The optimized kernels reuse input feature maps from the shared memory and sparse weights from registers. For multi-GPU parallelism, our SpDNN implementation duplicates weights and statically partition the feature maps across GPUs. Results for the challenge benchmarks show that the proposed kernel design and multi-GPU parallelization achieve up to 180 tera-edges per second inference throughput. These results are up to 4.3x faster for a single GPU and an order of magnitude faster at full scale than those of the champion of the 2019 Sparse Deep Neural Network Graph Challenge for the same generation of NVIDIA V100 GPUs. Using the same implementation, we also show single-GPU throughput on NVIDIA A100 is 2.37$\times$ faster than V100.

description: We determine the geometry of supersymmetric heterotic string backgrounds for which all parallel spinors with respect to the connection $\hat\nabla$ with torsion $H$, the NS$\otimes$NS three-form field strength, are Killing. We find that there are two classes of such backgrounds, the null and the timelike. The Killing spinors of the null backgrounds have stability subgroups $K\ltimes\bR^8$ in $Spin(9,1)$, for $K=Spin(7)$, SU(4), $Sp(2)$, $SU(2)\times SU(2)$ and $\{1\}$, and the Killing spinors of the timelike backgrounds have stability subgroups $G_2$, SU(3), SU(2) and $\{1\}$. The former admit a single null $\hat\nabla$-parallel vector field while the latter admit a timelike and two, three, five and nine spacelike $\hat\nabla$-parallel vector fields, respectively. The spacetime of the null backgrounds is a Lorentzian two-parameter family of Riemannian manifolds $B$ with skew-symmetric torsion. If the rotation of the null vector field vanishes, the holonomy of the connection with torsion of $B$ is contained in $K$. The spacetime of time-like backgrounds is a principal bundle $P$ with fibre a Lorentzian Lie group and base space a suitable Riemannian manifold with skew-symmetric torsion. The principal bundle is equipped with a connection $λ$ which determines the non-horizontal part of the spacetime metric and of $H$. The curvature of $λ$ takes values in an appropriate Lie algebra constructed from that of $K$. In addition $dH$ has only horizontal components and contains the Pontrjagin class of $P$. We have computed in all cases the Killing spinor bilinears, expressed the fluxes in terms of the geometry and determine the field equations that are implied by the Killing spinor equations.

description: In this work, we study possible hidden-bottom molecular pentaquarks $P_b$ from coupled-channel $Σ^{(*)}_bB^{(*)}-Λ_bB^{(*)}$ interaction in the quasipotential Bethe-Salpeter equation approach. In isodoublet sector with $I=1/2$, with the same reasonable parameters the interaction produces seven molecular states, a state near $ Σ_bB$ threshold with spin parity $J^P=1/2^-$, a state near $Σ^*_bB$ threshold with $3/2^-$, two states near $Σ_bB^*$ threshold with $1/2^-$ and $3/2^-$, and three states near $Σ_b^*B^*$ threshold with $1/2^-$, $3/2^-$, and $5/2^-$. The results suggest that three states near $Σ_b^* B^*$ threshold and two states near $Σ_b B^*$ threshold are very close, respectively, which may be difficult to distinguish in experiment without partial wave analysis. Compared with the hidden-charm pentaquark, the $P_b$ states are relatively narrow with widths at an order of magnitude of 1 MeV or smaller. The importance of each channel considered is also discussed, and it is found that the $Λ_b B^*$ channel provides important contribution for the widths of those states. In isoquartet sector with $I=3/2$, cutoff should be considerably enlarged to achieve bound states from the interaction, which makes the existence of such states unreliable. The results in the current work are helpful for searching for hidden-bottom molecular pentaquarks in future experiments, such as the COMPASS, J-PARC, and the Electron Ion Collider in China (EicC).

description: We demonstrate Bragg diffraction of the antibiotic ciprofloxacin and the dye molecule phthalocyanine at a thick optical grating. The observed patterns show a single dominant diffraction order with the expected dependence on the incidence angle as well as oscillating population transfer between the undiffracted and diffracted beams. We achieve an equal-amplitude splitting of $14 \hbar k$ (photon momenta) and maximum momentum transfer of $18 \hbar k$. This paves the way for efficient, large-momentum beam splitters and mirrors for hot and complex molecules.

description: For an oriented virtual link, L.H. Kauffman defined the f-polynomial (Jones polynomial). The supporting genus of a virtual link diagram is the minimal genus of a surface in which the diagram can be embedded. In this paper we show that the span of the f-polynomial of an alternating virtual link L is determined by the number of crossings of any alternating diagram of L and the supporting genus of the diagram. It is a generalization of Kauffman-Murasugi-Thistlethwaite's theorem. We also prove a similar result for a virtual link diagram that is obtained from an alternating virtual link diagram by virtualizing one real crossing. As a consequence, such a diagram is not equivalent to a classical link diagram.

description: Background: To explore how the efficacy of product trials for skin cosmetics can be improved through the use of consumer-level images taken by volunteers using a conventional smartphone. Materials and Methods: 12 women aged 30 to 60 years participated in a product trial and had close-up images of the cheek and temple regions of their faces taken with a high-resolution Antera 3D CS camera at the start and end of a 4-week period. Additionally, they each had ``selfies'' of the same regions of their faces taken regularly throughout the trial period. Automatic image analysis to identify changes in skin colour used three kinds of colour normalisation and analysis for wrinkle composition identified edges and calculated their magnitude. Results: Images taken at the start and end of the trial acted as baseline ground truth for normalisation of smartphone images and showed large changes in both colour and wrinkle magnitude during the trial for many volunteers. Conclusions: Results demonstrate that regular use of selfie smartphone images within trial periods can add value to interpretation of the efficacy of the trial.

description: We propose a method for searching dark matter axion in axion-photon conversion. We consider a superconductor of cylindrical shape under strong magnetic field. The dark matter axion generates oscillating electric field which induces oscillating superconducting current in the surface of the superconductor. The current gives rise to dipole radiation with the frequency $m_a/2π$ given by axion mass $m_a$. We show that the radiation flux generated by the current is of the order of $10^{-18}$W under magnetic field $\sim 3$T in the case of radius $\sim 1$cm and length $\sim 10$cm of the cylindrical superconductor. %The superconducting current flows in the surface to the depth $λ\simeq 5\times 10^{-6}$cm. The large amount of the radiation flux arises because Cooper pairs with large number density ( $\sim 10^{22}/\rm cm^{3}$ ) is present in the superconductor. With the high detection sensitivity, we can simultaneously search wide bandwidth of the radio frequency with existing radio telescope.

description: Testing, tracking and tracing abilities have been identified as pivotal in helping countries to safely reopen activities after the first wave of the COVID-19 virus. Contact tracing apps give the unprecedented possibility to reconstruct graphs of daily contacts, so the question is who should be tested? As human contact networks are known to exhibit community structure, in this paper we show that the Kemeny constant of a graph can be used to identify and analyze bridges between communities in a graph. Our "Kemeny indicator" is the change in Kemeny constant when a node or edge is removed from the graph. We show that testing individuals who are associated with large values of the Kemeny indicator can help in efficiently intercepting new virus outbreaks, when they are still in their early stage. Extensive simulations provide promising results in early identification and in blocking possible "super-spreaders" links that transmit disease between different communities.

Channelization architecture for wide-band slow light in atomic vapors

description: We propose a ``channelization'' architecture to achieve wide-band electromagnetically induced transparency (EIT) and ultra-slow light propagation in atomic Rb-87 vapors. EIT and slow light are achieved by shining a strong, resonant ``pump'' laser on the atomic medium, which allows slow and unattenuated propagation of a weaker ``signal'' beam, but only when a two-photon resonance condition is satisfied. Our wideband architecture is accomplished by dispersing a wideband signal spatially, transverse to the propagation direction, prior to entering the atomic cell. When particular Zeeman sub-levels are used in the EIT system, then one can introduce a magnetic field with a linear gradient such that the two-photon resonance condition is satisfied for each individual frequency component. Because slow light is a group velocity effect, utilizing differential phase shifts across the spectrum of a light pulse, one must then introduce a slight mismatch from perfect resonance to induce a delay. We present a model which accounts for diffusion of the atoms in the varying magnetic field as well as interaction with levels outside the ideal three-level system on which EIT is based. We find the maximum delay-bandwidth product decreases with bandwidth, and that delay-bandwidth product ~1 should be achievable with bandwidth ~50 MHz (~5 ns delay). This is a large improvement over the ~1 MHz bandwidths in conventional slow light systems and could be of use in signal processing applications.

description: Applying the Gordon-decomposition-like technique, the convective spin current (CSC) is extracted from the total angular-momentum current. The CSC describes the transport properties of the electron spin and is conserved in the relativistic quantum mechanics approach where the spin-orbit coupling has been intrinsically taken into account. Arrestingly, in the presence of external electromagnetic field, the component of the convective spin along the field remain still conserved. This conserved CSC is also derived for the first time in the nonrelativistic limit using the Foldy-Wouthuysen transformation.

description: In this Letter, we present a rigorous method to study the stability of periodic lasing systems. In a linear model, the presence of a continuum of modes (with arbitrarily close lasing thresholds) gives the impression that stable single-mode lasing cannot be maintained in the limit of an infinite system. However, we show that nonlinear effects of the Maxwell-Bloch equations can lead to stable systems near threshold given a simple stability condition on the sign of the laser detuning compared to the band curvature. We examine band-edge (1d) and bound-in-continuum (2d) lasing modes and validate our stability results against time-domain simulations.
