title: Rezension: Januschek, Franz (2018), Über SpracheSpielen. Einübung in die Kunst des Erwägens von Alternativen. Duisburg: Universitätsverlag Rhein-Ruhr
Creators: name: Briese, Joschka

description: „Das Erwägen von Alternativen“, so fasst Januschek gegen Ende seines Buches zusammen, „kann sich weder mit der Orientierung an der Realität begnügen, noch kann es sich aus ihr hinausphantasieren“ (251). Dieser Satz, welcher die vorherigen Kapitel resümiert, fasst nicht nur die wesentlichen Elemente der sprachtheoretischen Orientierung Januscheks zusammen, sondern zeigt auch deren spielerisches Potenzial. Zwischen Realität und Phantasie, so lässt sich Januscheks grundlegende These und auch dessen langjährige wissenschaftliche Arbeit rekapitulieren, liegt ein schöpferisches Moment, welches für Sprachtheorie, (Schrift-)Spracherwerb, kritische Diskursanalyse und Fremd- bzw. Mehrsprachigkeitsdidaktik fruchtbar zu machen sei. Über SpracheSpielen. Einübung in die Kunst des Erwägens von Alternativen, das zwischen sprachtheoretischer Abhandlung und populärwissenschaftlicher Literatur oszilliert und deshalb mit seiner Genrezugehörigkeit spielt, zeigt eben jenes schöpferische Moment in un-terschiedlichen Forschungsbereichen auf und versucht es, sowohl spielerisch als auch konkret, in die Sprachwis-senschaft zu integrieren.

The production of neutron beams using the associated particle technique
Creators: name: Tripard, Gerald Edward
Publisher: name: University of British Columbia
Year: 2011

description: Accurately collimated monoenergetic fast neutron beams of small angular width were produced by bombarding heavy ice targets with deuterons, and operating the neutron detector in coincidence with a semiconductor detector detecting the He³ recoil nuclei. Using a bombarding energy of E[subscript d] 50 keV a neutron beam of energy 2.55 MeV and known absolute intensity was produced. The measured beam profile agreed with the theoretically calculated profile. The beam was used to measure the absolute neutron detection efficiency and the pulse spectrum of a plastic scintillation counter bombarded by 2.55 MeV neutrons. Using a bombarding energy of E[subscript d] = 2 MeV a neutron beam of energy 5.08 MeV was produced and the bearers profile was measured.

description: Time-resolved Raman spectroscopy has been applied to probe the anharmonic coupling and electron-phonon interaction of optical phonons in graphite. From the decay of the transient anti-Stokes scattering of the G-mode following ultrafast excitation, we measured a lifetime of 2.2+/-0.1ps for zone-center optical phonons. We also observed a transient stiffening of G-mode phonons, an effect attributed to the reduction of the electron-phonon coupling for high electronic temperatures.

description: Epitaxial oxide interfaces with broken translational symmetry have emerged as a central paradigm behind the novel behaviors of oxide superlattices. Here, we use scanning transmission electron microscopy to demonstrate a direct, quantitative unit-cell-by-unit-cell mapping of lattice parameters and oxygen octahedral rotations across the BiFeO3-La0.7Sr0.3MnO3 interface to elucidate how the change of crystal symmetry is accommodated. Combined with low-loss electron energy loss spectroscopy imaging, we demonstrate a mesoscopic antiferrodistortive phase transition and elucidate associated changes in electronic properties in a thin layer directly adjacent to the interface.
Specific Heat-Coefficient of YbAl3 Studied by Combined Nearly Free Electron Conduction Band Hybridized with Localized f Electrons with Correlation Effect

Publisher: name: arXiv
Year: 2009
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Based on the recently proposed band model, the electronic specific heat of moderately heavy electron compound YbAl$_3$ are investigated. The band term of the Hamiltonian consists of three parts; conduction electrons described by the nearly free electron method, localized 4f electrons of Yb ions and the hybridization term between these electrons. Extracting several bands near the Fermi level, we reconstruct the low-energy effective Hamiltonian in order to consider the correlation effect, which is studied by using the self-consistent second order perturbation theory combined with local approximation. The temperature dependence of the specific heat $c_{\rm v}(T)$ is calculated as a function of temperature $T$ from the numerical derivative of the internal energy. Sommerfeld coefficient $γ$ is also calculated from the direct formula. The overall structure of $c_{\rm v}(T)/T$ is in quantitative agreement with the experimental results, which have the characteristic two-peak structures. They originate from the correlation effect and the structure of the non-interacting density of states, respectively. We show that our effective Hamiltonian yielding the realistic band structure may describe quantitatively heavy electron compounds with conduction bands composed of s- or p- electrons.

Phantom-like effects in asymmetric brane embedding with induced gravity and the Gauss-Bonnet term in the Bulk

description: We construct an asymmetric braneworld embedding with induced gravity on the brane, where stringy effects are taken into account by incorporation of the Gauss-Bonnet term in the bulk action. We derive the effective Friedmann equation of the brane and then we investigate the possible realization of the phantom-like behavior in this setup. We show that in the absence of the Gauss-Bonnet term in the bulk action (a pure induced gravity scenario), the phantom-like behavior in asymmetric case can be realized in smaller redshift than the corresponding symmetric case. We show also that in the general case with curvature effect, the phantom-like behavior can be realized in two subcases: in a symmetric subcase and also in an asymmetric branch of the solutions. In either cases this phantom-like behavior happens without introducing any phantom fields neither on the brane nor in the bulk.

description: Boolean networks have long been used as models of molecular networks and play an increasingly important role in systems biology. This paper describes a software package, Polynome, offered as a web service, that helps users construct Boolean network models based on experimental data and biological input. The key feature is a discrete analog of parameter estimation for continuous models. With only experimental data as input, the software can be used as a tool for reverse-engineering of Boolean network models from experimental time course data.

description: Der vorliegende Sammelband fußt auf den Erkenntnissen und Vorträgen der gleichnamigen Tagung „Normative Grundlagen und reflexive Verortungen im Feld DaF und DaZ*“ vom September 2015 an der Universität Wien. Das Sternchen bei DaZ, welches auch schon im Titel des Sammelbandes zu sehen ist, ist angelehnt an İnci Dirims Vortrag „Postkoloniale Perspektiven auf DaZ“ vom Juni 2015 an der Universität Wien und soll einen kritisch-reflexiven Umgang mit dem DaZ-Begriff aufgrund seines differenzkonstruierenden Charakters nahelegen. Folglich wird – wie in der Tagung – auch im Sammelband auf die Frage nach den normativen Gegebenheiten in den Disziplinen DaF und DaZ eingegangen. Die kritisch-analytische Auseinandersetzung mit diesen beiden Formen der Deutschdidaktik, welche nach den Herausgeberinnen İnci Dirim und Anke Wegner nicht nur die Lehre eines simplen und pragmatischen Kommunikationsmittels darstellt, sondern auch mit gesellschaftlich-politischen Hegemonien korreliert, sei „für die (weitere) Konstitution des Faches unerlässlich“ (11). Angesichts dieser Sachlage zielt der Band insbesondere darauf ab, die Ziele und Arbeitsweisen von drei Tätigkeitsfeldern des Faches (Zielsetzungen, Forschungsmethoden, Praxis- und Politikbezug) zu analysieren, welche es dem Fach sowohl auf deutschsprachiger (DaZ) als auch auf internationaler (DaF) Ebene bisher erschwert haben, eine konvergente und wissenschaftstheoretische Positionierung einzunehmen (vgl. 12)

Reconstruction of potential energy profiles from multiple rupture time distributions

description: We explore the mathematical and numerical aspects of reconstructing a potential energy profile of a molecular bond from its rupture time distribution. While reliable reconstruction of gross attributes, such as the height and the width of an energy barrier, can be easily extracted from a single first passage time (FPT) distribution, the reconstruction of finer structure is ill-conditioned. More careful analysis shows the existence of optimal bond potential amplitudes (represented by an effective Peclet number) and initial bond configurations that yield the most efficient numerical reconstruction of simple potentials. Furthermore, we show that reconstruction of more complex potentials containing multiple minima can be achieved by simultaneously using two or more measured FPT distributions, obtained under different physical conditions. For example, by changing the effective potential energy surface by known amounts, additional measured FPT distributions improve the reconstruction. We demonstrate the possibility of reconstructing potentials with multiple minima, motivate heuristic rules-of-thumb for optimizing the reconstruction, and discuss further applications and extensions.

description: We investigate by Monte Carlo simulations the structure, energetics and superfluid properties of thin helium-four films (up to four layers) on a glass substrate, at low temperature. The first adsorbed layer is found to be solid and "inert", i.e., atoms are localized and do not participate to quantum exchanges. Additional layers are liquid, with no clear layer separation above the second one. It is found that a single helium-three impurity resides on the outmost layer, not significantly further away from the substrate than helium-four atoms on the same layer.

description: Disorder plays an important role in two dimensions, and is responsible for striking phenomena such as metal insulator transition and the integral and fractional quantum Hall effects. In this paper, we investigate the role of disorder in the context of the recently discovered topological insulator, which possesses a pair of helical edge states with opposing spins moving in opposite directions and exhibits the phenomenon of quantum spin Hall effect. We predict an unexpected and nontrivial quantum phase termed "topological Anderson insulator," which is obtained by introducing impurities in a two-dimensional metal; here disorder not only causes metal insulator transition, as anticipated, but is fundamentally responsible for creating extended edge states. We determine the phase diagram of the topological Anderson insulator and outline its experimental consequences.

An investigation into the Mossbauer effect in Fe57
Creators: name: Woodrow, Janice Emily Jean
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis the Mossbauer effect in metallic iron has been studied as a function of the length of time of diffusion of the Co⁵⁷ source into metallic iron, of the source temperature over the range 156°K to 478°K, and of the absorber thickness. In each case, the line shape, width, intensity and shifts were measured. Measurements showed that the appearance of an appreciable Mossbauer effect, .122, arises within the first ten minutes of diffusion time at 900°C in a hydrogen atmosphere and that additional time is required to reduce the line width and to increase the intensity to .145. The observed temperature shift of the resonantly absorbed 14.4 kev radiation followed that which was predicted by the Josephson effect. However, corrections for an isomer and a hydrostatic compression shift were made to the data before comparing the measured shift with the theoretical shift. The results indicated a Debye temperature of Θ[subscript D] = (420±20)°K for both the source and absorber used. The measurements made over the temperature range indicated that the internal magnetic field H̰ followed the saturation magnetization curve (the Weiss Law) closely. For small temperature differences between the source and absorber, ΔΘ < 50°K, measurements were made indicating that the minimum line width occurred at ΔΘ = 24°K. These results indicated that the internal magnetic field at ΔΘ = 0°K for the source was .01x10⁵oe greater than that of the absorber. For ΔΘ ≥ 100°K, the Mossbauer line displayed a hyperfine structure arising from the temperature dependent difference in the internal magnetic field at the nuclei. The line profile, width, shift and intensity were measured for four absorber thicknesses - .0002", .00035", .00055", and .001". The detailed comparison of these line characteristics with the theoretical values required an extension of existing treatments, a discussion of which is given in chapter five. In each case it was observed that the Mossbauer line was accompanied by two small peaks, one on either side of the main line. The position of these peaks indicated that they were associated with a small or zero internal magnetic field at the site of some of the Fe⁵⁷ atoms.

description: On-chip Electron Spin Resonance (ESR) of magnetic molecules requires the ability to precisely position nanosized samples in antinodes of the electro-magnetic field for maximal magnetic interaction. A method is developed to entrap micro-crystals containing spins in a well defined location on a substrate's surface. Traditional cavity ESR measurements are then performed on a mesoscopic crystal at 34 GHz. Polycrystalline diluted Cr$^{5+}$ spins were entrapped as well and measured while approaching the lower limit of the ESR sensitivity. This method suggests the feasibility of on-chip ESR measurements at dilution refrigerator temperatures by enabling the positioning of samples atop an on-chip superconducting cavity.

description: trilingualism, multilingualism and tertiary language learning have been around for a long time, but they were not recognized as special cases of language acquisition and language competence. Only recently have researchers begun to check out what distinguishes third and fourth language learning/acquisition from second language learning/acquisition and to search for differences and common features in bilingualism and tri-/multilingualism. Around the globe, researchers are working in areas like sociolinguistics, psycholinguistics and educational linguistics in order to determine the scope of trilingualism and related areas. We were fascinated to see the broad variety of research questions, topics, methods, and languages under investigation when we opened the Innsbruck International Conference on Third Language Acquisition and Trilingualism in September 1999.

description: In dem Artikel wird die spezifische interkulturelle Kompetenz der jungen spanischen MigrantInnen in der Kommunikation im deutschsprachigen Raum untersucht. Während der Erwerb der lexikalischen und grammatikalischen Fertigkeiten in dieser Gruppe in der Regel in zufriedenstellendem Maße erfolgt, bereitet der Erwerb der spezifischen interkulturellen Kompetenz in einigen Bereichen noch beachtenswerte Schwierigkeiten. In der vorliegenden empirischen Untersuchung konzentrieren wir uns auf die Bereiche der relativen Direktheit in der Kommunikation im Deutschen, im Unterschied zum Spanischen, und der relativen Distanziertheit. Die Ergebnisse, die im Rahmen mehrerer Gruppendiskussionen und einer Umfrage mit 171 Teilnehmern erhoben wurden, zeigen, dass sich beide Bereiche für einen Großteil der Informanten problematisch gestalten.

description: In this paper, we discuss the energy-momentum problem in the realm of teleparallel gravity. The energy-momentum distribution for a class of regular black holes coupled with a non-linear electrodynamics source is investigated by using Hamiltonian approach of teleparallel theory. The generalized regular black hole contains two specific parameters $α$ and $β$ (a sort of dipole and quadrupole of non-linear source) on which the energy distribution depends. It is interesting to mention here that our results exactly coincide with different energy-momentum prescriptions in General Relativity.

description: We prove local in time well-posedness for the Zakharov system in two space dimensions with large initial data in L^2 x H^{-1/2} x H^{-3/2}. This is the space of optimal regularity in the sense that the data-to-solution map fails to be smooth at the origin for any rougher pair of spaces in the L^2-based Sobolev scale. Moreover, it is a natural space for the Cauchy problem in view of the subsonic limit equation, namely the focusing cubic nonlinear Schroedinger equation. The existence time we obtain depends only upon the corresponding norms of the initial data - a result which is false for the cubic nonlinear Schroedinger equation in dimension two - and it is optimal because Glangetas-Merle's solutions blow up at that time.

description: In light of some recent experiments on quasi two-dimensional (2D) turbulent channel flow we provide here a model of the ideal case, for the sake of comparison. The ideal 2D channel flow differs from its 3D counterpart by having a second quadratic conserved variable in addition to the energy, and the latter has an inverse rather than a direct cascade. The resulting qualitative differences in profiles of velocity, V, and energy, K, as a function of the distance from the wall are highlighted and explained. The most glaring difference is that the 2D channel is much more energetic, with K in wall units increasing logarithmically with the Reynolds number $\Ret$ instead of being $\Ret$-independent in 3D channels.

Precursor ionization

Publisher: name: University of British Columbia

description: The preionization of a shock tube's gas before the shock passes through it is called the precursor effect. An experimental and theoretical study has been carried out on precursor ionization in an electromagnetic shock tube. The precursor ionization was detected with different types of electric probes and also with photoraaltipliers. Extensive experiments indicated that the ionization was not due to diffusion of particles from the discharge in the shock tube driver. The ionization is primarily caused by radiation from the discharge of wavelengths less than 2000 Å. Radiation from the shock front makes a negligible contribution to the ionization. Langmuir double probe measurements indicated that the gas was about 0.1% ionized and that the electrons in the precursor were not in thermal equilibrium with the gas atoms and ions. The time interval between detection of ionization at two stations was independent of the shock tube gas (air, argon, helium), and corresponded to a propagation speed greater than 1/20 the speed of light. The precursor had a main component lasting about 50 microseconds with ionization proportional to the square of the discharge current. There was also a weaker component which lasted for about 500 microseconds. The experimental results can be understood in terms of a theoretical model based on black body radiation. Considering the driver to act as an infinite slab radiator, whose temperature is a function of the discharge parameters, an expression is derived for the number of photons emitted in some frequency interval. Assuming the electron density to be proportional to radiation absorption from such a radiator, the electron density variation with distance from the driver can be adequately understood. When the shock tube is considered to behave as a transmission line, whose resistance per unit length is proportional to the electron density, one can explain the variation of the shock tube's gas potential both with distance from the driver and with time.

description: The collective properties of different quasiparticles in various graphene based structures in high magnetic field have been studied. We predict Bose-Einstein condensation (BEC) and superfluidity of 2D spatially indirect magnetoexcitons in two-layer graphene. The superfluid density and the temperature of the Kosterlitz-Thouless phase transition are shown to be increasing functions of the excitonic density but decreasing functions of magnetic field and the interlayer separation. The instability of the ground state of the interacting 2D indirect magnetoexcitons in a slab of superlattice with alternating electron and hole graphene layers (GLs) is established. The stable system of indirect 2D magnetobiexcitons, consisting of pair of indirect excitons with opposite dipole moments, is considered in graphene superlattice. The superfluid density and the temperature of the Kosterlitz-Thouless phase transition for magnetobiexcitons in graphene superlattice are obtained. Besides, the BEC of excitonic polaritons in GL embedded in a semiconductor microcavity in high magnetic field is predicted. While superfluid phase in this magnetoexciton polariton system is absent due to vanishing of magnetoexciton-magnetoexciton interaction in a single layer in the limit of high magnetic field, the critical temperature of BEC formation is calculated. The essential property of magnetoexcitonic systems based on graphene (in contrast, e.g., to a quantum well) is stronger influence of magnetic field and weaker influence of disorder. Observation of the BEC and superfluidity of 2D quasiparticles in graphene in high magnetic field would be interesting confirmation of the phenomena we have described.

description: This paper contains locally rotationally symmetric kinematic self-similar perfect fluid and dust solutions. We consider three families of metrics which admit kinematic self-similar vectors of the first, second, zeroth and infinite kinds, not only for the tilted fluid case but also for the parallel and orthogonal cases. It is found that the orthogonal case gives contradiction both in perfect fluid and dust cases for all the three metrics while the tilted case reduces to the parallel case in both perfect fluid and dust cases for the second metric. The remaining cases give self-similar solutions of different kinds. We obtain a total of seventeen independent solutions out of which two are vacuum. The third metric yields contradiction in all the cases.

description: In diesem Artikel werden Ergebnisse von Interviews mit insgesamt zwanzig Fremdsprachenlehrpersonen aus der Deutschschweiz präsentiert, die an einer Studie zur Erforschung der Mehrsprachigkeitsdidaktik im schulischen Fremdsprachenunterricht teilgenommen haben. Diese Lehrpersonen und ihre Klassen (Primar- und Sekundarstufe), die Französisch und Englisch als schulische Fremdsprachen lernen, haben während vier Lektionen à 45 Minuten an mehrsprachigkeitsdidaktischen Aktivitäten gearbeitet und wurden dabei gefilmt. In anschliessenden Interviews wurden die Lehrpersonen um ihre Einschätzungen 1) der soeben durchgeführten Aktivitäten und 2) des Stellenwerts von mehrsprachigkeitsdidaktischen Ansätzen im Fremdsprachenunterricht gebeten. Die Ergebnisse zeigen, dass die Lehrpersonen die Prinzipien der Mehrsprachigkeitsdidaktik grundsätzlich gut finden. Gleichzeitig weisen sie auf erhebliche Herausforderungen bei ihrem Einsatz im Fremdsprachenunterricht hin.

description: Sensing characteristics of few-layer graphenes for NO2 and humidity have been investigated with graphene samples prepared by the thermal exfoliation of graphitic oxide (EG), conversion of nanodiamond (DG) and arc-discharge of graphite in hydrogen (HG). The sensitivity for NO2 is found to be highest with DG. Nitrogen-doped HG (n-type) shows increased sensitivity for NO2 compared to pure HG. The highest sensitivity for humidity is observed with HG. The sensing characteristics of graphene have been examined for different aliphatic alcohols and the sensitivity is found to vary with the chain length and branching.

description: For many, spiritual beliefs and religious affiliation exist as a protective factor, providing significant emotional, psychological, and social support (Ibrahim & Dykeman, 2011). However, for others, abuse within the power structures of religion can also inflict great harm—particularly within marginalized communities—resulting in religious trauma. The LGBTQIA+ community has historically experienced marginalization and discrimination within various religious contexts and doctrines, becoming a group particularly vulnerable to religious trauma (Simmons et al., 2017; Swindle, 2017). This type of trauma has often been overlooked in the therapy room and within the broader Marriage and Family Therapy field. This thesis addresses this gap through the creation of an introductory training for therapists on religious trauma that many in LGBTQIA+ community experience. Grounded in religious trauma research and trauma-informed client care, the training seeks to enhance therapists' capacity to navigate these complex terrains with empathetic and informed care (Ellis et al., 2022). The aim is to create a therapeutic landscape where healing and self-compassion become more accessible to LGBTQIA+ individuals impacted by religious trauma.
Integrated FAHP-FDEMATEL for determining causal relationships in construction crew productivity modelling

Construction crew productivity is affected by the motivation of the crew performing given activities and by situational/contextual factors forming the dynamic construction environment. The literature lacks a comprehensive analysis of

causal relationships between crew motivation and situational/contextual factors for dynamic modelling of crew productivity.

The contributions of this paper are (1) identifying a set of criteria for performing expert weight assignment for heterogenous

group experts in productivity research, (2) proposing an integrated fuzzy analytic hierarchy process–fuzzy decision-making

trial and evaluation laboratory approach that provides a systematic, structured method for determining causal relationship

mapping between factors affecting crew productivity, and (3) proposing an approach for identifying cause-and-effect groups

among the situational/contextual factors and crew motivation, which can further be used to formulate strategic productivity

improvement solutions. The proposed methodology is demonstrated using a case study on an actual industrial construction

project in Alberta, Canada.

Some consequences of time-reversal symmetry
Creators: name: Maroun, David Peter
Publisher: name: University of British Columbia
Year: 2011

description: The purpose -of this work is to discuss the symmetry, or lack of it, under reversal of motion in physical objects, states and processes. Considerations of such symmetry are made in both classical and quantum physics, notably in the problem of reconciling the assumed time-reversal symmetry of microscopic processes with the observed asymmetry of macroscopic processes. In the case of classical mechanics, a simple model of a free particle colliding with a series of almost stationary or stationary particles of smaller mass is introduced in order to show how a friction-like phenomenon can arise from processes all of which have symmetry under reversal of motion. It is maintained throughout that symmetry under reversal of motion is a property of all fundamental states and processes in nature.
