Prophet, priest, and king: an interpretive rewriting of an English teacher’s vocation
Creators: name: Wiebe, Sean
Publisher: name: University of British Columbia
Year: 2009

description: In this inquiry I examine the spiritual significance of English pedagogy through a rewriting of my spiritual and pedagogical voices: prophet, priest, and king. Being poetic, the inquiry "plays out" my teaching experiences stressing the ambivalence of language and the pervasiveness of metaphor. With each word the poetry shifts, its meaning likewise, and with every shift this inquiry is destabilized. At the same time, because each word holds a history of infinite facets, everything depends on the words. Thus, somewhere between each shift grows an intertextual relationship of the prophet, priest, and kingly voices. Keeping the poetic voices constantly in play, constantly combining and recombining them in provocative new ways, is the emerging nature of this inquiry. Emerging in this way, the point of my re-search is to explore further what a spiritual English pedagogy itself entails, particularly, staying open to the lived experience, which in turn leads to deeper understandings. Thus, this inquiry is not framed in traditional modes of pedagogical inquiry. It has been the result of living in tension—so much so that what has emerged is not another teaching model, frame, or skeleton, but the breath of poetry which brings a skeleton life. It is my central purpose to "play out" my existential experience of English pedagogy. My poetic reflections, will not only contribute to our knowledge of English teaching and the curriculum, but also will anticipate a fuller understanding of spirituality and education as a source of possibility.

description: We study the behavior of the Horrocks-Mumford bundle when restricted to a plane P^2 in P^4, looking for all possible minimal free resolutions for the restricted bundle. To each of the 6 resolutions (4 stable and 2 unstable) we find, we then associate a subvariety of the Grassmannian G(2,4) of planes in P^4. We thus obtain a filtration of the Grassmannian, which we describe in the second part of this work.

description: We present a general study of the large family of exact integrable quantum chains with multispin interactions introduced recently in \cite{AP2020}. The exact integrability follows from the algebraic properties of the energy density operators defining the quantum chains. The Hamiltonians are characterized by a parameter $p=1,2,\dots$ related to the number of interacting spins in the multispin interaction. In the general case the quantum spins are of infinite dimension. In special cases, characterized by the parameter $N=2,3,\ldots$, the quantum chains describe the dynamics of $Z(N)$ quantum spin chains. The simplest case $p=1$ corresponds to the free fermionic quantum Ising chain ($N=2$) or the $Z(N)$ free parafermionic quantum chain. The eigenenergies of the quantum chains are given in terms of the roots of special polynomials, and for general values of $p$ the quantum chains are characterized by a free fermionic ($N=2$) or free parafermionic ($N>2$) eigenspectrum. The models have a special critical point when all coupling constants are equal. At this point the ground-state energy is exactly calculated in the bulk limit, and our analytical and numerical analyses indicate that the models belong to universality classes of critical behavior with dynamical critical exponent $z = (p+1)/N$ and specific-heat exponent $α= \max\{0,1-(p+1)/N\}$.

The role of EFL teachers in Japan : negotiation of cultures
Creators: name: Uchida, Yuko
Publisher: name: University of British Columbia
Year: 2009

description: This study explored how EFL teachers in Japan with various backgrounds perceive their roles in relation to the teaching of culture and, further, investigated how such perceptions shaped (and were shaped by) their lived experiences of teaching English. Since the mid-1980s, Japan has been undergoing controversial educational reforms emphasizing communicative English teaching with a focus on the teaching of foreign cultures. The dramatic increase in foreign English teachers, the cultural diversity of the teachers, and the rise and decline of the English language school industry are part of the unique backdrop for this study. Taking a qualitative research approach, a variety of procedures were employed for data collection: questionnaires, class observations, post-observation interviews, and weekly retrospective journals. Two female Japanese and two American (one male and one female) EFL teachers participated in the study for one semester (over a five-month period). Teachers' perceptions were found to be deeply embedded in the individuals' personal histories as cultural beings, based on their educational, professional, and cultural experiences (biographical/professional basis), and subject to constant negotiation due to changing contextual elements (i.e., classroom culture, institutional culture, and textbook). Thus, the study illuminated the teachers' role in interfacing a "curriculum-asplan" and a "lived curriculum". The complexity of the teachers' identities, their struggle for "connection," and their struggle with the "education-control dilemma" emerged as common themes. Therefore, I argued that the issue of culture teaching in EFL classrooms requires a new approach to analyzing and preparing teachers and curricula. Implications for ESL/EFL teacher education and curriculum development with respect to taking a new view of teachers as dynamic, but complex, agents are suggested. Finally, the possibility of collaborative research in effecting desirable educational change is considered.

description: Motivated by recent studies of superconformal mechanics extended by spin degrees of freedom, we construct minimally superintegrable models of spinning particles on 2-sphere, the spin degrees of freedom of which are represented by a 3-vector obeying the structure relations of a 3d real Lie algebra. Generalisations involving an external field of the Dirac monopole, or the motion on the group manifold of SU(2), or a scalar potential giving rise to two quadratic constants of the motion are discussed. A procedure how to build similar extensions, which rely upon d=4,5,6 real Lie algebras, is elucidated.

description: Welsh Wreck Web Research Project unpublished report series, 1
description: The Viscata was a wooden schooner of 77 tons built at Aberdovey in 1856 by an unidentified builder. The first owners recorded for the Viscata are Jones and Co who registered it in Aberystwith. The Viscata was used to carry various cargo's between Wales, Ireland, France, England and Holland with some visits to Scotland. Viscata had three different owners but its port of registration remained the same. The final owner of Viscata, Evan Evans was also the master. Viscata sank 12 miles west of Bardsey Island on a voyage from Bantry to Liverpool in January 1880, when she sprang a leak during a force 8 gale from the S.S.W. The crew used the ships boat to save themselves and were rescued after spending 12 hours over night attempting to row for the shore. The five men who rowed out to save them were awarded �2 by the RNLI in recognition of their actions.

description: The equation of state of SU(3) Yang-Mills theory can be modelled by an effective $Z_3-$symmetric potential $V(\vertϕ\vert,ϕ^3+ϕ^{3*}, T)$ depending on the temperature $T$ and on a scalar field $ϕ$ -- the averaged Polyakov loop. Allowing $ϕ$ to be dynamical opens the way to the study of spatially localized classical configurations of the Polyakov loop. We first show that spherically symmetric static Q-balls exist in the range $(1-1.21)\times T_c$, $T_c$ being the deconfinement temperature. Then we argue that Q-holes solutions, if any are unphysical within our framework. Finally we couple the Polyakov-loop Lagrangian to Einstein gravity and show that spherically symmetric static boson stars exist in the same range of temperature. The Q-ball and boson star solutions we find can be interpreted as "bubbles" of deconfined gluonic matter; their mean radius is always smaller than 10 fm.

description: We study locally constant coefficients. We first study the theory of homotopy Kan extensions with locally constant coefficients in model categories, and explain how it characterizes the homotopy theory of small categories. We explain how to interpret this in terms of left Bousfield localization of categories of diagrams with values in a combinatorial model category. At last, we explain how the theory of homotopy Kan extensions in derivators can be used to understand locally constant functors.

description: We report the discovery of a new Einstein cross at redshift z_S = 2.701 based on Lyman-alpha emission in a cruciform configuration around an SDSS luminous red galaxy (z_L = 0.331). The system was targeted as a possible lens based on an anomalous emission line in the SDSS spectrum. Imaging and spectroscopy from the W. M. Keck Observatory confirm the lensing nature of this system. This is one of the widest-separation galaxy-scale lenses known, with an Einstein radius of ~1.84 arcsec. We present simple gravitational lens models for the system and compute the intrinsic properties of the lensed galaxy. The total mass of the lensing galaxy within the 8.8 +/- 0.1 kpc enclosed by the lensed images is (5.2 +/- 0.1) x 10^11 M_sun. The lensed galaxy is a low mass galaxy (0.2 L*) with a high equivalent-width Lyman-alpha line (EW_Lya_rest = 46 +/- 5 Angstroms). Follow-up studies of this lens system can probe the mass structure of the lensing galaxy, and can provide a unique view of an intrinsically faint, high-redshift, star-forming galaxy at high signal-to-noise ratio.

description: When measuring the value of the Hubble parameter, $H_0$, it is necessary to know the recession velocity free of the effects of peculiar velocities. In this work, we study different models of peculiar velocity in the local Universe. In particular, we compare models based on density reconstruction from galaxy redshift surveys and kernel smoothing of peculiar velocity data. The velocity field from the density reconstruction is obtained using the 2M++ galaxy redshift compilation, which is compared to two adaptive kernel-smoothed velocity fields: the first obtained from the 6dF Fundamental Plane sample and the other using a Tully-Fisher catalogue obtained by combining SFI++ and 2MTF. We highlight that smoothed velocity fields should be rescaled to obtain unbiased velocity estimates. Comparing the predictions of these models to the observations from a few test sets of peculiar velocity data, obtained from the Second Amendment Supernovae catalogue and the Tully-Fisher catalogues, we find that 2M++ reconstruction provides a better model of the peculiar velocity in the local Universe than the kernel-smoothed peculiar velocity models. We study the impact of peculiar velocities on the measurement of $H_0$ from gravitational waves and megamasers. In doing so, we introduce a probabilistic framework to marginalize over the peculiar velocity corrections along the line-of-sight. For the megamasers, we find $H_0 = 69^{+2.9}_{-2.8}$ km s^{-1} Mpc^{-1} using the 2M++ velocity field. We also study the peculiar velocity of the the galaxy NGC1052-DF2, concluding that a short $\sim$ 13 Mpc distance is not a likely explanation of the anomalously low dark matter fraction of that galaxy.

description: The ``moving puncture'' technique has led to dramatic advancements in the numerical simulations of binary black holes. Hannam et.al. have recently demonstrated that, for suitable gauge conditions commonly employed in moving puncture simulations, the evolution of a single black hole leads to a well-known time-independent, maximal slicing of Schwarzschild. They construct the corresponding solution in isotropic coordinates numerically and demonstrate its usefulness, for example for testing and calibrating numerical codes that employ moving puncture techniques. In this Brief Report we point out that this solution can also be constructed analytically, making it even more useful as a test case for numerical codes.

Contrary to individual MWNT, where the observed power laws are attributed to Coulomb blockade, the measured ratio for the end and bulk obtained exponents, ~2.4, can only be accounted for by LL theory. At temperatures characteristic of interband separation, it increases due to thermal population of the conducting sheets unoccupied bands.

While large (20 nm) nanocrystals display the same vibrational spectra as their microcrystalline counterparts, we find an enhanced phonon density of states at low energies, $E \leq 15\,\rm{meV}$, in ultra-small (5 nm) NaGd$_{0.8}$Yb$_{0.18}$Er$_{0.02}$F$_4$ nanocrystals which we assign to an increased relative spectral weight of surface phonon modes. Based on our observations for ultra-small nanocrystals, we rationalize that an increase of the phonon density of states in large nanocrystals due to surface phonons is too small to be observed in the current measurements. The experimental approach described in this report constitutes the first step toward the rationalization of size effects on the modification of the absolute upconversion quantum yield of upconverting nanocrystals.

description: Welsh Wreck Web Research Project unpublished report series, 1
description: The Volunteer was built in 1865 in Ardrossan, Scotland by Barclay and Shearer for Deakins and Co., of Runcorn but was partly owned in Ardrossan by ship agent Duncan Stewart. The master Thomas Deakin was part owner, with his son Thomas becoming the mate in 1868 and another son Richard an able seaman. The Volunteer made voyages to Spain, Portugal and South America and the mate Thomas Deakin junior was arrested for smuggling in 1870. The elder Deakin was fined for employing him as a mate while uncertificated. The Volunteer ran aground several times, exploded and required repairs for leaks in its short lifetime. The Volunteer was on passage from Ardrossan to Newport with pig iron when she was in collision with the screw steamer Demetrius about 10 miles from Cardigan Bay light ship. The Volunteer immediately started to take water and sank in minutes. The master Thomas Deakin went down with the vessel and the remaining crew were landed at Liverpool by the Demetrius.

description: Moving from a National Grid Testbed to a Production quality Grid service for the HEP applications requires an effective operations structure and organization, proper user and operations support, flexible and efficient management and monitoring tools. Moreover the middleware releases should be easily deployable using flexible configuration tools, suitable for various and different local computing farms. The organizational model, the available tools and the agreed procedures for operating the national/regional grid infrastructures that are part of the world-wide EGEE grid as well as the interconnection of the regional operations structures with the global management, control and support structure play a key role for the success of a real production grid. In this paper we describe the operations structure that we are currently using at the Italian Grid Operation and Support Center. The activities described cover monitoring, management and support for the INFN-GRID/Grid.It production grid (spread over more than 30 sites) and its interconnection with the EGEE/LCG structure as well as the roadmap to improve the global support quality, stability and reliability of the Grid service.

Κοινό σημείο των λογοτεχνικών ιστοριών αποτελεί ο κεντρικός ήρωας, ένα ψάρι που διαφέρει στην εμφάνιση από όλα τα άλλα ψάρια της κοινωνίας του βυθού. Στόχος της εργασίας είναι να διερευνήσει και να καταγράψει τα ιδιαίτερα χαρακτηριστικά της ιδιαίτερης αυτής κοινωνίας, πώς συναισθάνονται τα μέλη της την ετερότητα, πώς βιώνουν την περιθωριοποίηση καθώς και σε ποιο βαθμό επιτυγχάνει ο συγγραφέας να ανατρέψει τα στερεότυπα και τις προκαταλήψεις. Αρχικά, αναλύεται θεωρητικά όλο το πλαίσιο των εννοιών της ταυτότητας και της ετερότητας, δύο έννοιες με πολλαπλές διαστάσεις αφού η παγκοσμιοποίηση, οι οικονομικές αλλαγές, η ραγδαία τεχνολογική εξέλιξη, οι πρόσφατες πολιτικές εξελίξεις, διαδραματίζουν σπουδαίο ρόλο στην μεταμοντέρνα κοινωνία. Στη συνέχεια αναλύονται όλα τα μοντέλα διαχείρισης της πολιτισμικότητας καθώς αναφέρονται τα θεσμικά μέτρα διαπολιτισμικής εκπαίδευσης και η εκπαιδευτική πολιτική στην Ελλάδα, την εποχή συγγραφής των έργων.

description: This paper investigates the subject of diversity in Vangelis Iliopoulos's children's literature books. Common point of the literary stories is their main character: a fish, which differs in appearance from all other fish of the seabed society. The aims of this paper are to investigate and document the specifics of this particular society, how its members become aware of diversity, how they experience marginalisation, and to what degree the author manages to overturn the stereotypes and prejudices. Firstly, it analyses theoretically the overall context of the concepts of identity and diversity, two concepts with multiple dimensions, as globalisation, economic change, rapid technological development, and recent political developments, play an important role in post-modern society. Secondly, it analyses models of managing multiculturalism, and describes institutional measures of multicultural education and educational policies in Greece during the time the stories were written. It also describes the theoretical pedagogical approaches which informed the analysis and it makes reference to the author's life. Finally, it analyses the stories using the aforementioned analysis methods, it interprets the results and it formulates final conclusions.

description: Software module clustering is an unsupervised learning method used to cluster software entities (e.g., classes, modules, or files) with similar features. The obtained clusters may be used to study, analyze, and understand the software entities' structure and behavior. Implementing software module clustering with optimal results is challenging. Accordingly, researchers have addressed many aspects of software module clustering in the past decade. Thus, it is essential to present the research evidence that has been published in this area. In this study, 143 research papers from well-known literature databases that examined software module clustering were reviewed to extract useful data. The obtained data were then used to answer several research questions regarding state-of-the-art clustering approaches, applications of clustering in software engineering, clustering processes, clustering algorithms, and evaluation methods. Several research gaps and challenges in software module clustering are discussed in this paper to provide a useful reference for researchers in this field.

description: Named Entity Recognition (NER) is a challenging task that extracts named entities from unstructured text data, including news, articles, social comments, etc. The NER system has been studied for decades. Recently, the development of Deep Neural Networks and the progress of pre-trained word embedding have become a driving force for NER. Under such circumstances, how to make full use of the information extracted by word embedding requires more in-depth research. In this paper, we propose an Adversarial Trained LSTM-CNN (ASTRAL) system to improve the current NER method from both the model structure and the training process. In order to make use of the spatial information between adjacent words, Gated-CNN is introduced to fuse the information of adjacent words. Besides, a specific Adversarial training method is proposed to deal with the overfitting problem in NER. We add perturbation to variables in the network during the training process, making the variables more diverse, improving the generalization and robustness of the model. Our model is evaluated on three benchmarks, CoNLL-03, OntoNotes 5.0, and WNUT-17, achieving state-of-the-art results. Ablation study and case study also show that our system can converge faster and is less prone to overfitting.

Το δυναμικό σύστημα αποτελείται από έναν αστέρα, με μάζα ίση με την μάζα του Ήλιου, έναν πλανήτη (BP), με μάζα ίση με την μάζα του Δία, που περιφέρεται γύρω από τον αστέρα (αρχικό ζεύγος) και έναν ελεύθερο πλανήτη (FFP), πάλι με μάζα ίση με την μάζα του Δία, τον οποίο αρχικά τοποθετούμε σε τέτοια απόσταση από το ζεύγος ώστε να θεωρούμε ότι δεν επηρεάζεται από το βαρυτικό δυναμικό του ζεύγους. Αρχικά, το ζεύγος βρίσκεται πάνω στο επίπδεο xy ενώ ο ελεύθερος πλανήτης βρίσκεται πάνω στην επιφάνεια μίας σφαίρας και ξεκινάει να κινείται προς το αρχικό ζεύγος.

Μεταβάλλοντας την αρχική φάση του BP, την αρχική θέση του ελεύθερου πλανήτη πάνω στην σφαιρική επιφάνεια και τον προσανατολισμό του διανύσματος της ταχύτητάς του ως προς το ζεύγος προσπαθήσαμε να χαρτογραφήσουμε και να μελετήσουμε στατιστικά τις τέσσερις πιθανές εκβάσεις αυτής της αλληλεπίδρασης: προπέραση, προσωρινή σύλληψη, ανταλλαγή και διαάλυση του δυναμικού συστήματος. Επίσης, χρησιμοποιήσαμε την συνάρτηση και την ανισότητα του Sundman σε μία προσπάθεια πρόβλεψης του αποτελέσματος της παραπάνω αλληλεπίδρασης, με στόχο την αποφυγή χρονοβόρων υπολογισμών για το εν λόγω δυναμκό σύστημα.
description: We perform a three-dimensional study of the interaction of a free-floating planet approaching a star-planet pair. The dynamical system consists of a Sun-like star and a Jupiter-like planet (BP) orbiting the star (binary system) plus a Jupiter-like free-floating planet (FFP) placed sufficiently away from the gravitational potential of the binary system. Initially the binary system lays on the xy-plane while the FFP is fired from a spherical surface and has a parabolic velocity with respect to the star, that points at the binary. By changing the initial phase angle of the BP, as well as the initial position of the FFP on the spherical surface and the orientation of the velocity vector, we have tried to map and statistically study the four possible outcomes of this encounter: flyby, resonance, exchange and disruption of the system. We also tried to incorporate the Sundman's function and inequality in the integration, in an effort to predict the final outcome of the system avoiding the need for lengthy computations.

description: The validity of Hubble's law defies the determination of the center of the big bang expansion, even if it exists. Every point in the expanding universe looks like the center from which the rest of the universe flies away. In this article, the author shows that the distribution of apparently circular galaxies is not uniform in the sky and that there exists a special direction in the universe in our neighborhood. The data is consistent with the assumption that the tidal force due to the mass distribution around the universe center causes the deformation of galactic shapes depending on its orientation and location relative to the center and our galaxy. Moreover, the cmb dipole data can also be associated with the center of the universe expansion, if the cmb dipole at the center of our supercluster is assumed to be due to Hubble flow. The location of the center is estimated from the cmb dipole data. The direction to the center from both sets of data is consistent and the distance to the center is computed from the cmb dipole data.

description: We study the attractor mechanism for extremal non-BPS black holes with an infinite throat near horizon geometry, developing, as we do so, a physical argument as to why such a mechanism does not exist in non-extremal cases. We present a detailed derivation of the non-supersymmetric attractor equation. This equation defines the stabilization of moduli near the black hole horizon: the fixed moduli take values specified by electric and magnetic charges corresponding to the fluxes in a Calabi Yau compactification of string theory. They also define the so-called double-extremal solutions. In some examples, studied previously by Tripathy and Trivedi, we solve the equation and show that the moduli are fixed at values which may also be derived from the critical points of the black hole potential.

description: Η πλειοψηφία των σύγχρονων μελετητών ερμήνευσε την θεωρία ιδιοκτησίας του Καντ ως αξίωση για απουσία εξωτερικών καταναγκασμών από την απόλαυση της ελευθερίας και συνεπώς της ιδιοκτησίας καθενός. Σε αυτή την εργασία υποστηρίζουμε πως οι σχέσεις ιδιοκτησίας είναι πρώτα και πάνω απ’ όλα κοινωνικές σχέσεις οι οποίες φέρουν άμεσο αντίκτυπο στην ελευθερία όλων των υπολοίπων. Μέσα από μια εκτενή και ολοκληρωμένη ανάλυση των αυθεντικών κειμένων του Καντ καταλήγουμε πως η ιδιοκτησία οφείλει να ρυθμίζεται από τους κοινωνικούς θεσμούς μέσα από τις αρχές της ίσης ελευθερία μεταξύ των πολιτών, της ουσιαστικής ελευθερίας για κάθε πρόσωπο και της πραγματικής δυνατότητας κάθε πρόσωπο να στηρίζεται στις δικές του πνευματικές και φυσικές δυνάμεις για να καλύπτει τις βασικές βιοφυσικές του ανάγκες.
description: Contemporary political philosophers have mainly interpreted Kant’s theory of property as articulated in his theory of justice in a minimalistic context where the liberty of each person and therefore his property is an absolute right that must be guaranteed against external coercions. In this paper, we argue that property relations are first and foremost social relations among persons and therefore they always bear a negative aspect of exclusion to all other co-citizens. Through an extensive and comprehensive analysis of Kant’s original texts we support that property must be regulated by the social institutions of the state through the values of equal liberty among citizens, of substantial freedom for every person and of the actual possibility for each person to rely on his own mental and physical powers.

description: We have calculated the emission spectra of Y and N and invariant masses of YN pairs in the direct K-NN --> YN absorption process at rest in 4He and light nuclei in order to provide theoretical tools for correct interpretations of experimental data with or without invoking kaonic nuclear bound states. All the momentum distributions are broad with widths around 150-200 MeV/c (except for the case of 6Li target), while the partial invariant mass of each YN pair has a peak around 2310-2330 MeV/c2. We argue against the interpretations of stopped-K- experimental data of KEK and FINUDA by Oset and Toki and by Magas, Oset, Ramos and Toki.

description: We find the free field construction of the basic $W$-current and screening currents for the deformed $W$-superalgebra ${\cal W}_{q,t}\bigl(A(M,N)\bigr)$ associated with Lie superalgebra of type $A(M,N)$. Using this free field construction, we introduce the higher $W$-currents and obtain a closed set of quadratic relations among them. These relations are independent of the choice of Dynkin-diagrams for the Lie superalgebra $A(M,N)$, though the screening currents are not. This allows us to define ${\cal W}_{q,t}\bigl(A(M,N)\bigr)$ by generators and relations.

description: Η καθιέρωση της διδασκαλίας της αγγλικής γλώσσας ως πρώτης ξένης γλώσσας στην ελληνική πρωτοβάθμια εκπαίδευση, έχει προσφέρει τροφή για σκέψη και ενδελεχή έρευνα σε θέματα διδασκαλίας και εκμάθησης σε μαθητές νεαρής ηλικίας. Η εκμάθηση ξένων γλωσσών βρίσκεται στο επίκεντρο του ενδιαφέροντος τόσο της ΕΕ όσο και της Ελλάδας λόγω της ζωτικής της σημασίας στη διάπλαση της προσωπικότητας των παιδιών και των πολλαπλών οφελών που προσφέρει στην εκπαίδευση, στην απασχολησιμότητα, στην κινητικότητα αλλά και στη συμβολή της προς το άνοιγμα σε διαφορετικές γλώσσες και πολιτισμούς. Στο πρώτο μέρος επιτυγχάνεται η διερεύνηση της γλωσσικής πολιτικής της ΕΕ αφού αναφερθούν οι ενέργειες που καταβάλλει για την προώθηση της πολυγλωσσίας στα κράτη μέλη. Στη συνέχεια, αναλύεται η γλωσσική πολιτική της Ελλάδας αναφορικά με τον ρόλο των ξένων γλωσσών στο ελληνικό δημόσιο σχολείο δίνοντας ιδιαίτερη έμφαση στην αγγλική γλώσσα. Σκοπός είναι η εξέταση των στάσεων της ελληνικής γλωσσικής πολιτικής απέναντι στην πολυγλωσσία και στην πολύγλωσση κοινωνία. Στην παρούσα εργασία σκιαγραφείται το γλωσσικό προφίλ των μαθητών της Πρωτοβάθμιας Εκπαίδευσης που διδάσκονται τα αγγλικά ως ξένη γλώσσα μέσω ενός εργαλείου κατασκευασμένο ειδικά για αυτό τον σκοπό. Τα αποτελέσματα της έρευνας δείχνουν πως οι μαθητές διαθέτουν ένα πλούσιο γλωσσικό προφίλ, γεγονός που συνεπάγεται περαιτέρω μελλοντική συζήτηση και διερεύνηση.
description: The introduction of the instruction of English as a first foreign language in the Greek primary education, has provided food for thought and thorough research on teaching and learning of young students. Learning foreign languages is at the center of interest of both the EU and Greece due to its vital importance in the formation of the personality of children, multiple benefits concerning education, employability, mobility and its contribution towards the openness to different languages and cultures. In the first part, EU language policy is investigated through referring to the practices made to promote multilingualism in the member states. In the second part, Greece's language policy is analyzed with a view to the role of foreign languages in public school and special emphasis on the English language. The purpose of the study is to examine the attitudes of Greece's language policy towards multilingualism and multilingual society. This paper outlines the language profiles of pupils in primary education who are taught English as a foreign language through a tool designed especially for this purpose. The research results demonstrate that students have rich language profiles, providing opportunity for further thought and discussion.

description: Let $λ$ be a positive number, and let $(x_j:j\in\mathbb Z)\subset\mathbb R$ be a fixed Riesz-basis sequence, namely, $(x_j)$ is strictly increasing, and the set of functions $\{\mathbb R\ni t\mapsto e^{ix_jt}:j\in\mathbb Z\}$ is a Riesz basis ({\it i.e.,} unconditionalbasis) for $L_2[-π,π]$. Given a function $f\in L_2(\mathbb R)$ whose Fourier transform is zero almost everywhere outside the interval $[-π,π]$, there is a unique square-summable sequence $(a_j:j\in\mathbb Z)$, depending on $λ$ and $f$, such that the function$$I_λ(f)(x):=\sum_{j\in\mathbb Z}a_je^{-λ(x-x_j)^2}, \qquad x\in\mathbb R, $$ is continuous and square integrable on $(-\infty,\infty)$, and satisfies the interpolatory conditions $I_λ(f)(x_j)=f(x_j)$, $j\in\mathbb Z$. It is shown that $I_λ(f)$ converges to $f$ in $L_2(\mathbb R)$, and also uniformly on $\mathbb R$, as $λ\to0^+$. A multidimensional version of this result is also obtained. In addition, the fundamental functions for the univariate interpolation process are defined, and some of their basic properties, including their exponential decay for large argument, are established. It is further shown that the associated interpolation operators are bounded on $\ell_p(\mathbb Z)$ for every $p\in[1,\infty]$.

description: We use quantum scattering theory to study a fixed quantum system Y subject to collisions with massive particles X described by wave-packets. We derive the scattering map for system Y and show that the induced evolution crucially depends on the width of the incident wave-packets compared to the level spacing in Y . If Y is non-degenerate, sequential collisions with narrow wave-packets cause Y to decohere. Moreover, an ensemble of narrow packets produced by thermal effusion causes Y to thermalize. On the other hand, broad wave-packets can act as a source of coherences for Y , even in the case of an ensemble of incident wave-packets given by the effusion distribution, preventing thermalization. We illustrate our findings on several simple examples and discuss the consequences of our results in realistic experimental situations.

description: In this paper, we identify optimal swimming strategies for drag-dominated swimmers with a passive elastic joint. We use resistive force theory (RFT) to obtain the dynamics of the system. We then use frequency domain analysis to relate the motion of the passive joint to the motion of the actuated joint. We couple this analysis with elements of the geometric framework introduced in our previous work aimed at identifying useful gaits for systems in drag dominated environments, to identify speed-maximizing and efficiency-maximizing gaits for drag-dominated swimmers with a passive elastic joint.
