description: In this article, we present an analysis of the practices of a physics teacher, during two practical sessions, one of which is conducted according to the inquiry based science teaching process. This research is part of the theoretical framework of the dual didactic and ergonomic approach. In a first level of analysis of the results, resulting from two class observations and interviews of self-confrontation, we access the logic of actions of the teacher and the determinants of his practices. A second level of comparative analysis of the results allows us to identify the invariants and the regularities in the practices of this teacher and to infer possible evolutions in these practices.

description: An integrable theory is developed for the perturbation equations engendered from small disturbances of solutions. It includes various integrable properties of the perturbation equations: hereditary recursion operators, master symmetries, linear representations (Lax and zero curvature representations) and Hamiltonian structures etc. and provides us a method to generate hereditary operators, Hamiltonian operators and symplectic operators starting from the known ones. The resulting perturbation equations give rise to a sort of integrable coupling of soliton equations. Two examples (MKdV hierarchy and KP equation) are carefully carried out.

description: A delayed detached eddy simulation (DDES) of an overexpanded nozzle flow with shock-induced separation is carried out at a Reynolds number equal to 1.7 10^7. The flow unsteadiness, characterised by self-sustained shock oscillations, induces local unsteady loads on the nozzle wall as well as global off-axis forces. A clear physical understanding of the driving factors of the unsteadiness is still lacking. Under the current conditions, the nozzle operates in a highly-overexpanded regime and comprises a conical separation shock within the nozzle contour, merging into a Mach disk in the nozzle centre. Our current study focuses on the unsteady pressure signature on the nozzle wall, through the use of Fourier-based spectral analysis performed in time and in the azimuthal wavenumber space. The numerical data well agrees with the experimental measurements in terms of mean and fluctuating wall pressure statistics. The frequency spectra are characterised by the presence of a large bump in the low frequency range associated to a breathing motion of the shock system and a broad and high amplitude peak at high frequencies generated by the turbulent activity of the detached shear layer. Moreover, a distinct peak at an intermediate frequency (of the order 1000 Hz) is observed to persist in the wall-pressure spectra along the nozzle wall. The analysis of the pressure signals in the azimuthal wavenumber space indicates that this peak is clearly associated to the first (non-symmetrical) pressure mode and it is thus connected to the generation of side loads. Furthermore, it is found that the unsteady Mach disk is characterised by an intense vortex shedding activity and the interaction of these vortices with the second shock cell is a key factor in the sustainment of an aeroacoustic feedback loop within the nozzle.

description: We consider quantum correlation functions of the antiferromagnetic spin-$\frac{1}{2}$ Heisenberg XXZ spin chain in a magnetic field. We show that for a magnetic field close to the critical field $h_c$ (for the critical magnetic field the ground state is ferromagnetic) certain correlation functions can be expressed in terms of the solution of the Painlevé V transcendent. This establishes a relation between solutions of Painlevé differential equations and quantum correlation functions in models of {\sl interacting} fermions. Painlevé transcendents were known to describe correlation functions in models with free fermionic spectra.

description: Obtaining complete information about the shape of an object by looking at it from a single direction is impossible in general. In this paper, we theoretically study obtaining differential geometric information of an object from orthogonal projections in a number of directions. We discuss relations between (1) a space curve and the projected curves from several distinct directions, and (2) a surface and the apparent contours of projections from several distinct directions, in terms of differential geometry and singularity theory. In particular, formulae for recovering certain information on the original curves or surfaces from their projected images are given.

description: While theoretical arguments predict that most of the early growth of supermassive black holes (SMBHs) happened during heavily obscured phases of accretion, current methods used for selecting $z>6$ quasars (QSOs) are strongly biased against obscured QSOs, thus considerably limiting our understanding of accreting SMBHs during the first Gyr of the Universe from an observational point of view. We report the $Chandra$ discovery of the first heavily obscured QSO candidate in the early universe, hosted by a close ($\approx5$ kpc) galaxy pair at $z=6.515$. One of the members is an optically classified type 1 QSO, PSO167-13. The companion galaxy was first detected as a [C II] emitter by ALMA. An X-ray source is significantly ($P=0.9996$) detected by $Chandra$ in the 2-5 keV band, with $<1.14$ net counts in the 0.5-2 keV band, although the current positional uncertainty does not allow a conclusive association with either PSO167-13 or its companion galaxy. From X-ray photometry and hardness-ratio arguments, we estimated an obscuring column density of $N_H>2\times10^{24}\,\mathrm{cm^{-2}}$ and $N_H>6\times10^{23}\,\mathrm{cm^{-2}}$ at $68\%$ and $90\%$ confidence levels, respectively. Thus, regardless of which of the two galaxies is associated with the X-ray emission, this source is the first heavily obscured QSO candidate at $z>6$.

description: Multivariate discrete outcomes are common in a wide range of areas including insurance, finance, and biology. When the interplay between outcomes is significant, quantifying dependencies among interrelated variables is of great importance. Due to their ability to accommodate dependence flexibly, copulas are being applied increasingly. Yet the application of copulas on discrete data is still in its infancy; one of the biggest barriers is the non-uniqueness of copulas, calling into question model interpretations and predictions. In this paper, we study copula estimation with discrete outcomes in a regression context. As the marginal distributions vary with covariates, inclusion of continuous regressors expands the region of support for consistent estimation of copulas. Because some properties of continuous outcomes do not carry over to discrete outcomes, specification of a copula model has been a problem. We propose a nonparametric estimator of copulas to identify the “hidden” dependence structure for discrete outcomes and develop its asymptotic properties. The proposed nonparametric estimator can also serve as a diagnostic tool for selecting a parametric form for copulas. In the simulation study, we explore the performance of the proposed estimator under different scenarios and provide guidance on when the choice of copulas is important. The performance of the estimator improves as discreteness diminishes. A practical bandwidth selector is also proposed. An empirical analysis examines a dataset from the Local Government Property Insurance Fund (LGPIF) in the state of Wisconsin. We apply the nonparametric estimator to model the dependence among claim frequencies from different types of insurance coverage.

The integrability of orbits of test particles moving around a black hole representing the galactic center is studied and bounded zones of chaotic behavior are found.

description: The adjustment and socialisation of newcomer staff members is an important component of any organisation’s Human Resources Management (HRM) concerns. Adjustment and socialisation influence staff members’ perceptions of the organisation along with their commitment, which may be evidenced by their job performance and intention to stay with the organisation. This concept is true for ethnically and linguistically diverse immigrant and host-country organisational newcomers and the colleagues with whom they work. Skilled labour shortages in Australia, increased mobility of international job-seekers, high immigration levels, and the strategic internationalisation of many organisations in Australia make the recruitment and retention of all staff, including ethnically and linguistically diverse staff, particularly important. Rigorous qualitative research on organisational adjustment and socialisation of ethnically and linguistically diverse newcomer staff, including immigrant staff, is scarce in existing literature. The present research addresses this gap by utilising an exploratory qualitative multiple case study and an interpretive interactionist approach to interrogate document and interview data. The perceptions of 16 recent immigrant and 17 Australian-born newcomers about their adjustment and socialisation in an Australian tertiary education providing organisation (the primary organisation) are explored. The newcomers are identified in terms of organisational position and area of employment, academic or general staff, gender, age, ethnicity, and country of origin. Benchmarking of policy and practice with comparable organisations in Australia is utilised to position the primary organisation in relation to other similar providers in the industry. Nine senior managers including a senior Human Resources (HR) manager in the primary organisation are interviewed about their perceptions of the phenomena of adjustment and socialisation of local and immigrant newcomer staff. Similarly, four senior HR managers from the benchmarked organisations are interviewed about the phenomena to provide a comparison across similar organisations in Australia. By comparing the findings across the datasets and in relation to the literature, a deeper understanding emerges of ethnically and linguistically diverse newcomer adjustment and socialisation in the primary and benchmarked organisations. From this understanding, applied contributions are developed which add to the existing body of adjustment and socialisation knowledge...
Economic Battery Storage Dispatch with Deep Reinforcement Learning from Rule-Based Demonstrations

description: The application of deep reinforcement learning algorithms to economic battery dispatch problems has significantly increased recently. However, optimizing battery dispatch over long horizons can be challenging due to delayed rewards. In our experiments we observe poor performance of popular actor-critic algorithms when trained on yearly episodes with hourly resolution. To address this, we propose an approach extending soft actor-critic (SAC) with learning from demonstrations. The special feature of our approach is that, due to the absence of expert demonstrations, the demonstration data is generated through simple, rule-based policies. We conduct a case study on a grid-connected microgrid and use if-then-else statements based on the wholesale price of electricity to collect demonstrations. These are stored in a separate replay buffer and sampled with linearly decaying probability along with the agent's own experiences. Despite these minimal modifications and the imperfections in the demonstration data, the results show a drastic performance improvement regarding both sample efficiency and final rewards. We further show that the proposed method reliably outperforms the demonstrator and is robust to the choice of rule, as long as the rule is sufficient to guide early training into the right direction.

description: As climate change impacts a growing number of aspects of economic activity, it is becoming ever more vital to understand how these effects will manifest. This work advances the study of the impacts of environmental change. First, I provide a panel analysis at the country level that identifies the effects of dust storms on economic activity in West Africa. I also find some evidence in the agricultural sector to support the finding of damaging effects. Second, I examine the extent to which dust storms and climate shocks affect migration in the same region. While temperatures and precipitation are found to play important roles, dust storms do not appear to have a significant influence. Third, I consider the role of adaptation to climate change in the United States. I build a model that predicts the locations most likely to be used in agriculture in the future, allowing for better forecasting of shifts in the areas used for agricultural production.

description: The past decade has witnessed dramatic changes in the oil and gas industry with the drilling and production extending into progressively deeper waters and higher operating pressures, therefore making it essential to gain a better understanding of the behaviour of gas hydrate at high pressure conditions. New experimental 3-phase H−LW−V (Hydrate−Liquid Water−Vapour) equilibrium data for nitrogen and H−LW−V (Hydrate−Liquid Water−Vapour) and H−LW−LHC (Hydrate−Liquid Water−Liquid Hydrocarbon) data for ethane and propane simple clathrate hydrates were generated by a reliable fixed-volume, isochoric, step-heating technique. The accuracy and reliability of the experimental measurements are demonstrated by comparing measurements with reliable literature data from different researchers. Additional experimental data up to high pressure (200 MPa when available) for CH4, C2H6, C3H8, i-C4H10, N2, Ar, Kr, Xe, H2S, O2, CO and CO2 clathrates have been gathered from literature. The Valderrama modification of the Patel-Teja (VPT) equation of state combined with non-density-dependent (NDD) mixing rules is used to model the fluid phases with previously reported binary interaction parameters. The hydrate-forming conditions are modelled by the solid solution theory of van der Waals and Platteeuw. Langmuir constants have been calculated by both Kihara potential as well as direct techniques. Model predictions are validated against independent experimental data and a good agreement between predictions and experimental data is observed, supporting the reliability of the developed model.

Under the assumption that $α= w / \lg σ$ characters fit into a single machine word $w$, we propose a keyword dictionary that represents $K$ in $n \lg σ+ Θ(k \lg n)$ bits of space, supporting all operations in $O(m / α+ \lg α)$ expected time on an input string of length $m$ in the word RAM model. This data structure is underlined with an exhaustive practical evaluation, highlighting the practical usefulness of the proposed data structure, especially for prefix searches - one of the most elementary keyword dictionary operations.

description: The objective of this paper is to study the teachers’ education at the University, through the prism of critical reflection. Considering critical reflection as a necessary qualification for professional development, we focus on a curriculum that cultivate critical thinking not only during the theoretical part of the studies (lectures, workshops etc), but in practicum too. In this area the student has the opportunity to be tested, to think and to reflect upon educational practices. During an investigation that took place in a Greek University, the need to strengthen the reflective skills of future teachers, as well as the potential benefits for their better preparation emerged.

description: Halved monotone triangles are a generalisation of vertically symmetric alternating sign matrices (VSASMs). We provide a weighted enumeration of halved monotone triangles with respect to a parameter which generalises the number of $-1$s in a VSASM. Among other things, this enables us to establish a generating function for vertically symmetric alternating sign trapezoids. Our results are mainly presented in terms of constant term expressions. For the proofs, we exploit Fischer's method of operator formulae as a key tool.

description: The boundary knot method (BKM) is a recent boundary-type radial basis function (RBF) collocation scheme for general PDEs. Like the method of fundamental solution (MFS), the RBF is employed to approximate the inhomogeneous terms via the dual reciprocity principle. Unlike the MFS, the method uses a nonsingular general solution instead of a singular fundamental solution to evaluate the homogeneous solution so as to circumvent the controversial artificial boundary outside the physical domain. The BKM is meshfree, superconvergent, integration free, very easy to learn and program. The original BKM, however, loses symmetricity in the presense of mixed boundary. In this study, by analogy with Hermite RBF interpolation, we developed a symmetric BKM scheme. The accuracy and efficiency of the symmetric BKM are also numerically validated in some 2D and 3D Helmholtz and diffusion reaction problems under complicated geometries.

Subjects: School engagement, elementary school, transcultural validation, disadvantaged background

description: The purpose of this study, which builds on the research on school engagement in youth from disadvantaged backgrounds, was to test the transcultural validation of the School Engagement Measure. First, a translation is presented, along with an assessment of its reliability and construct validity. Using hierarchical linear analysis, an in-depth validity assessment is then conducted to draw a more complete portrait of school engagement in cycle three elementary students attending schools at different levels of academic disadvantage. The translated instrument shows similar psychometric properties to those of the original English version. The results are relatively positive: students showed similar school engagement between the most and the least disadvantaged schools. The study limitations are discussed.

description: For incomplete preference relations that are represented by multiple priors and/or multiple -- possibly multivariate -- utility functions, we define a certainty equivalent as well as the utility buy and sell prices and indifference price bounds as set-valued functions of the claim. Furthermore, we motivate and introduce the notion of a weak and a strong certainty equivalent. We will show that our definitions contain as special cases some definitions found in the literature so far on complete or special incomplete preferences. We prove monotonicity and convexity properties of utility buy and sell prices that hold in total analogy to the properties of the scalar indifference prices for complete preferences. We show how the (weak and strong) set-valued certainty equivalent as well as the indifference price bounds can be computed or approximated by solving convex vector optimization problems. Numerical examples and their economic interpretations are given for the univariate as well as for the multivariate case.

Teacher-student relationships, social and emotional skills, and emotional and behavioural difficulties
Creators: name: POULOU, MARIA
Publisher: name: Educational Journal of the University of Patras UNESCO Chair
Year: 2014
Subjects: Emotional and behavioural difficulties, social and emotional learning, teacher-student relationships

description: In this study, the role of teacher-student relationships and students’ social and emotional skills as potential predictors of students’ emotional and behavioural difficulties was investigated by tapping into 962 primary school students’ perceptions via questionnaires. While significant correlations were found linking teachers’ interpersonal behaviour and students’ social and emotional skills to emotional and behavioural difficulties, data analysis indicated that students’ social and emotional skills were found to be more of a determinant of their behaviour than teachers’ interpersonal behaviour. Results are interpreted in relation to systems perspective and Social and Emotional Learning theory, and practical implications of the findings are discussed.

description: By rotating a half-line around its origin, we accomplish the scanning of a part of the plan. We get thus a right angle when this scanning covers one quarter of the plan. We also get a flat angle when it covers half of the plan when the covered part is one eighth of the plan, etc. As it is for the right angle of a right-angled triangle, each one of its two other angles is the part of the plan which is covered by the scanning accomplished by bringing the half-line support of the adjacent side of the angle, to the half-line, support of the hypotenuse of the triangle, and vice versa. Thus, it is possible to act on those scans by computing on the connections of the right-angled triangles right angles sides. In this article, we demonstrate that the movement on the grid also makes sense when it is conceived as an essence for this operation and those calculations. However this way is still a blind point of the successive didactical contracts that the didactical systems ties around the notion of angle particularly, and the trigonometry generally speaking.

description: Different methods allow technology teachers to approach the conception or the analysis of technical system. The origin of some methods is the functional analysis used in the industry. In France, the teacher in junior secondary schools uses them as classroom’s practices. With them the pupils can learn how the technical system works. But what do they really learn? Do we want them to apply a method or to understand the mechanism of a system? In this paper we study in which way the teachers interact with these instruments in the classroom. The study of the teacher’s practices is realized with a survey.

description: Develop skills in the training process requires reviewing not only programs but also educational organization, learning materials (textbooks), practices and initial and continuous training of teachers. Focus on the only change programs to improve the education system can even be an impasse as shown by our teacher survey concerned about the feasibility of the physics program of the final year science class developed in the framework of the competency-based approach (CPA). It appears from this survey that the main problems in the acquisition of knowledge are first in the application of programs within the allotted time in the training and preparation of teachers remains insufficient rather than content. In this paper we will try to highlight the ambiguity of the term, which present in the educational world, thereby justifying our questions about the necessity of the application of this approach to learning, having held the constraints it presents.

description: Let G be a semi-simple algebraic group over ${\mathbb C}$, B a Borel subgroup of G and T a maximal torus in B. A beautiful unpublished result of Dale Peterson says that if G is simply laced, then every rationally smooth point of a Schubert variety X in G/B is nonsingular in X. The purpose of this paper is to generalize this result to arbitrary T-stable subvarieties of G/B, the only restriction being that G contains no $G_2$ factors. In particular, we show that a Schubert variety X in such a G/B is nonsingular if and only if all the reduced tangent cones of X are linear.

description: Approximate Bayesian computation (ABC) has become an essential part of the Bayesian toolbox for addressing problems in which the likelihood is prohibitively expensive or entirely unknown, making it intractable. ABC defines a pseudo-posterior by comparing observed data with simulated data, traditionally based on some summary statistics, the elicitation of which is regarded as a key difficulty. Recently, using data discrepancy measures has been proposed in order to bypass the construction of summary statistics. Here we propose to use the importance-sampling ABC (IS-ABC) algorithm relying on the so-called two-sample energy statistic. We establish a new asymptotic result for the case where both the observed sample size and the simulated data sample size increase to infinity, which highlights to what extent the data discrepancy measure impacts the asymptotic pseudo-posterior. The result holds in the broad setting of IS-ABC methodologies, thus generalizing previous results that have been established only for rejection ABC algorithms. Furthermore, we propose a consistent V-statistic estimator of the energy statistic, under which we show that the large sample result holds, and prove that the rejection ABC algorithm, based on the energy statistic, generates pseudo-posterior distributions that achieves convergence to the correct limits, when implemented with rejection thresholds that converge to zero, in the finite sample setting. Our proposed energy statistic based ABC algorithm is demonstrated on a variety of models, including a Gaussian mixture, a moving-average model of order two, a bivariate beta and a multivariate $g$-and-$k$ distribution. We find that our proposed method compares well with alternative discrepancy measures.
