Understanding organizational boundaries
Creators: name: Jæger, Kirsten
name: Pedersen, Anne Grethe Julius
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2020

description: This article investigates various conceptualizations of organizational boundaries and seeks to establish a point of departure for the Globe special issue: Crossing organizational boundaries. It reviews literature that has paid attention to organizational boundaries in their own right and presents and discusses various definitions and categorizations of these boundaries. Because of the special issue’s concentration on the crossing of organizational boundaries, two concepts that have been particularly helpful for the understanding of cross-boundary interactions are discussed as well: the notion of boundary spanning implying the ability of maintaining and facilitating relations between distinct organizational entities and the concept of the boundary object, originally defined as a conceptual response to the challenge of understanding inter-organizational collaboration in practice. The notion of the boundary object has been a useful conceptual instrument for researchers studying the successful collaboration of actors with differing understandings of and interests in the subject of collaboration. In the article’s final section, the different contributions to the special issue are presented.

Adaptive grading systems, or pros and cons of different ways of grading grammar exams
Creators: name: Madsen, Richard Skultety
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2019

description: This paper investigates several alternatives to the grading system used currently when examining students’ knowledge of theoretical grammar in the Department of English Business Communication at Aalborg University, Denmark. The proposed alternatives differ from the current system in two parameters, namely by differentiating between exam questions according to their levels of difficulty and by evening out biases which are due to the differences in the weights of the various topics of the exam. It is found that the proposed methods would yield results significantly different from the current grading method even though it would only be in the favor of few students in terms of better grades to adapt any of them. Nevertheless, the study reveals prevalent traits of the current way of examining, such as built-in bias and the scalability of the questions, which are important considerations to anyone conducting exams, not just in grammar. Furthermore, the paper uncovers unexpected features of clause constituents that may have serious implications for their teaching.

On the Relativistic Description of the Nucleus

Year: 2005
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We present here a formalism able to generalise to a relativistically covariant scheme the standard nuclear shell model. We show that, using some generalised nuclear Green's functions and their Lehmann representation we can define the relativistic equivalent of the non relativistic single particle wave function (not loosing, however, the physical contribution of other degrees of freedom, like mesons and antinucleons). It is shown that the mass operator associated to the nuclear Green's function can be approximated with the equivalent of a shell-model potential and that the corresponding ``single particle wave functions'' can be easily derived in a specified frame of reference and then boosted to any other system, thus fully restoring the Lorentz covariance
Crossing hierarchies in organizations: Making sense of employee dissent and circumvention on internal social media
Creators: name: Madsen, Vibeke Thøis
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2019

description: This paper explores how and why visibility and persistence factors affect employee communication on internal social media (ISM) and influence organizational dissent. This study presents findings from a single case study conducted at a Danish bank. Discussions initiated by employees on ISM were studied for four months, and 24 employees were interviewed about their communication behavior and their perception of communication on ISM. The study found that employees would deliberately use the visibility of communication in the ISM arena to bring up issues that had been ignored by middle managers or support staff. Senior managers were perceived to watch the arena, influencing middle managers or other employees to respond. The efficacy of dissent therefore seemed to increase with the presence of ISM, especially when a post was perceived as well-formulated and an act of prosocial behavior. A new, unwritten rule, therefore, seemed to have emerged that dissent and even circumvention on ISM was acceptable when framed in a constructive manner and aired for the benefit of the organization.

Publications of A. A. Abrikosov from ALEXEI ALEKSEEVICH ABRIKOSOV. 25 June 1928 — 29 March 2017

subject: Quantum physics not elsewhere classified

description: A. A. Abrikosov was a consummate theoretical physicist whose work permeates modern quantum many-body physics. His greatest impact is the explanation of a regime of superconductivity in large magnetic fields, where the field penetrates the superconductor in quantized vortices, but the superconducting properties persist. For this work he won the 2003 Nobel Prize (together with V. L. Ginzburg ForMemRS and A. J. Leggett FRS). This is the framework for practical uses of superconductivity for high-field magnets, used for example in magnetic resonance imaging, magnetically levitating trains and the Large Hadron Collider. The ‘Abrikosov lattice’ of quantized vortices is a precursor to more recent understandings of two-dimensional magnetism, and topological materials whose properties are defined by quantized currents. He provided the earliest understanding of resummation of singularities in quantum theories, co-authored a textbook that has trained generations of theorists and led major research institutes and programmes in the USSR and the USA.

description: According to the most popular scenario, the early Universe should have experienced an accelerated expansion phase, called Cosmological Inflation, after which the standard Big Bang Cosmology would have taken place giving rise to the radiation-dominated epoch. However, the details of the inflationary scenario are far to be completely understood. Thus, in this paper we study if possible additional (exotic) cosmological phases could delay the beginning of the standard Big Bang history and alter some theoretical predictions related to the inflationary cosmological perturbations, like, for instance, the order of magnitude of the tensor-to-scalar ratio $r$.

description: The models based on ${SU}(3)_C\otimes {SU}(3)_L \otimes {U}(1)_X$ gauge group (3-3-1) contain new Higgs bosons and one of them is the SM-like Higgs boson $h$. Production of this Higgs boson at $p p$ colliders in the framework of 3-3-1 model with right-handed neutrinos is calculated. We found that the contribution of the real $Z^\prime$ to the process $pp\to hZ$ is nearly 60 fb if $M_{Z^\prime}$ is about 1 TeV. The decay width and the branching ratios of the $Z'$ extra neutral gauge boson are systematically discussed.

description: Bifurcation properties, stability behavior, dynamics, and the heat transfer of convection structures in a horizontal fluid layer that is driven away from thermal equilibrium by imposing a vertical temperature difference are compared with those resulting from imposing a heat current. In particular oscillatory convection that occurs in binary fluid mixtures in the form of travelling and standing waves is determined numerically for the two different driving mechanisms. Conditions are elucidated under which current driven convection is stable while temperature driven convection is unstable.

description: Solid-state spin defects are a promising platform for quantum science and technology, having realized demonstrations of a variety of key components for quantum information processing, particularly in the area of quantum networks. An outstanding challenge for building larger-scale quantum systems with solid-state defects is realizing high-fidelity control over multiple defects with nanoscale separations, which is required to realize strong spin-spin interactions for multi-qubit logic and the creation of entangled states. In this work, we experimentally demonstrate an optical frequency-domain multiplexing technique, allowing high-fidelity initialization and single-shot spin measurement of six rare earth (Er$^{3+}$) ions, within the sub-wavelength volume of a single, silicon photonic crystal cavity. We also demonstrate sub-wavelength control over coherent spin rotations using an optical AC Stark shift. The demonstrated approach may be scaled to large numbers of ions with arbitrarily small separation, and is a significant step towards realizing strongly interacting atomic defect arrays with applications to quantum information processing and fundamental studies of many-body dynamics.
The question of rhetorical agency in scientific communication: A case study
Creators: name: Coker, Wincharles
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2019

description: Though rhetorical scholars have argued that scientific inquiry does not lack human agency, our knowledge of how agency is enacted in scientific texts is blurred. Using abstracts from the American Journal of Bioethics, this paper argues and demonstrates how our understanding of rhetorical agency can be enhanced through the neglected theory of tagmemics. Intended as a heuristic, the paper argues that contributors to the American Journal of Bioethics are capable of constructing individual responsible agency that is in tandem with rhetorical choices they make within their community of consensus.

description: A problem of Banach asks whether every infinite-dimensional Banach space which is isomorphic to all its infinite-dimensional subspaces must be isomorphic to a separable Hilbert space. In this paper we prove a result of a Ramsey-theoretic nature which implies an interesting dichotomy for subspaces of Banach spaces. Combined with a result of Komorowski and Tomczak-Jaegermann, this gives a positive answer to Banach's problem. We then generalize the Ramsey-theoretic result and deduce a further dichotomy for Banach spaces with an unconditional basis.

The Hunger Games’ grammatik: Integreret grammatikundervisning i praksis
Creators: name: Jensen, Marie Møller
name: Haugaard, Marianne
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2019

description: This article examines the potential for integrated grammar teaching (IGT) based on stylistic analysis of the novel, The Hunger Games, in the Danish upper secondary educational system (HF). Since the 1990s, the importance of combining communication and grammar teaching has been emphasized; however, the Danish upper secondary schools have not embraced the scientific findings. This article exemplifies how to close the gap between research and reality with IGT through the following two perspectives: with an eye to developing teaching materials and through a stylistic analysis of chapter 11 of The Hunger Games, we firstly analyze how modality characterizes the narrator of The Hunger Games, Katniss. The stylistic analysis reveals that the homodiegetic narrator’s assessments of the hypothetical risks relating to the people and the world around her are expressed through epistemic modality in the form of modal verbs. Secondly, based on the stylistic analysis, we develop, test and discuss teaching materials for IGT for the English b-level[1] at HF. Our results demonstrate that IGT is challenging, motivating and educational: the pupils acquire the basic characteristics of modality to some degree and manage to use their linguistic findings to characterize the narrator. The evaluation shows that the learners could benefit from less concentrated IGT and more variation; this could possibly be achieved by mixing IGT with other aspects of the curriculum. The study also shows that, while it is possible to develop teaching material for IGT based on stylistic analysis, an in-depth stylistic analysis (like the one reported here) is not necessary for teaching at this level, an important factor which could reduce the teacher’s preparation time. [1] English b unofficially corresponds to B2 (Undervisningsministeriet 2018a) at the CEFR, The Common European Framework of Reference for Languages, put together by the Council of Europe (Exam English 2014).

description: P-stars are compact stars made of up and down quarks in $β$-equilibrium with electrons in a chromomagnetic condensate. We discuss p-stars endowed with super strong dipolar magnetic field which, following consolidated tradition in literature, are referred to as magnetars. We show that soft gamma-ray repeaters and anomalous $X$-ray pulsars can be understood within our theory. We find a well defined criterion to distinguish rotation powered pulsars from magnetic powered pulsars. We show that glitches, that in our magnetars are triggered by magnetic dissipative effects in the inner core, explain both the quiescent emission and bursts in soft gamma-ray repeaters and anomalous $X$-ray pulsars. We account for the braking glitch from SGR 1900+14 and the normal glitch from AXP 1E 2259+586 following a giant burst. We discuss and explain the observed anti correlation between hardness ratio and intensity. Within our magnetar theory we are able to account quantitatively for light curves for both gamma-ray repeaters and anomalous $X$-ray pulsars. In particular we explain the puzzling light curve after the June 18, 2002 giant burst from AXP 1E 2259+586.

description: Total energy electronic structure calculations, based on density functional theory or on the more empirical tight binding approach, are generally believed to scale as the cube of the number of electrons. By using the localisaton property of the high temperature density matrix we present exact deterministic algorithms that scale linearly in one dimension and quadratically in all others. We also introduce a stochastic algorithm that scales linearly with system size. These results hold for metallic and non metallic systems and are substantiated by numerical calculations on model systems.

description: Supernova spectral time series contain a wealth of information about the progenitor and explosion process of these energetic events. The modeling of these data requires the exploration of very high dimensional posterior probabilities with expensive radiative transfer codes. Even modest parametrizations of supernovae contain more than ten parameters and a detailed exploration demands at least several million function evaluations. Physically realistic models require at least tens of CPU minutes per evaluation putting a detailed reconstruction of the explosion out of reach of traditional methodology. The advent of widely available libraries for the training of neural networks combined with their ability to approximate almost arbitrary functions with high precision allows for a new approach to this problem. Instead of evaluating the radiative transfer model itself, one can build a neural network proxy trained on the simulations but evaluating orders of magnitude faster. Such a framework is called an emulator or surrogate model. In this work, we present an emulator for the TARDIS supernova radiative transfer code applied to Type Ia supernova spectra. We show that we can train an emulator for this problem given a modest training set of a hundred thousand spectra (easily calculable on modern supercomputers). The results show an accuracy on the percent level (that are dominated by the Monte Carlo nature of TARDIS and not the emulator) with a speedup of several orders of magnitude. This method has a much broader set of applications and is not limited to the presented problem.

description: It is expected that all astrophysical black holes in equilibrium are well described by the Kerr solution. Moreover, any black hole far away from equilibrium, such as one initially formed in a compact binary merger or by the collapse of a massive star, will eventually reach a final equilibrium Kerr state. At sufficiently late times in this process of reaching equilibrium, we expect that the black hole is modeled as a perturbation around the final state. The emitted gravitational waves will then be damped sinusoids with frequencies and damping times given by the quasinormal mode spectrum of the final Kerr black hole. An observational test of this scenario, often referred to as black hole spectroscopy, is one of the major goals of gravitational wave astronomy. It was recently suggested that the quasinormal mode description including the higher overtones might hold even right after the remnant black hole is first formed. At these times, the black hole is expected to be highly dynamical and nonlinear effects are likely to be important. In this paper we investigate this remarkable scenario in terms of the horizon dynamics. Working with high accuracy simulations of a simple configuration, namely the head-on collision of two nonspinning black holes with unequal masses, we study the dynamics of the final common horizon in terms of its shear and its multipole moments. We show that they are indeed well described by a superposition of ringdown modes as long as a sufficiently large number of higher overtones are included. This description holds even for the highly dynamical final black hole shortly after its formation. We discuss the implications and caveats of this result for black hole spectroscopy and for our understanding of the approach to equilibrium.

Using the spatially anisotropic triangular Heisenberg model we analyze previous and new performed NMR experiments. We compute the 1/T_1 relaxation time by means of the modified spin wave theory. The strong suppression of the nuclear relaxation time observed experimentally under varying pressure and magnetic field is qualitatively well reproduced by the model. Our results suggest the existence of a close relation between the effects of pressure and magnetic frustration.

description: The automorphism groups of the 27 lines on the smooth cubic surface or the 28 bitangents to the general quartic plane curve are well-known to be closely related to the Weyl groups of $E\_6$ and $E\_7$. We show how classical subconfigurations of lines, such as double-sixes, triple systems or Steiner sets, are easily constructed from certain models of the exceptional Lie algebras. For ${\mathfrak e}\_7$ and ${\mathfrak e}\_8$ we are lead to beautiful models graded over the octonions, which display these algebras as plane projective geometries of subalgebras. We also interpret the group of the bitangents as a group of transformations of the triangles in the Fano plane, and show how this allows to realize the isomorphism $PSL(3,F\_2)\simeq PSL(2,F\_7)$ in terms of harmonic cubes.

description: In a previous paper (hep-th/0407256) local scalar QFT (in Weyl algebraic approach) has been constructed on degenerate semi-Riemannian manifolds $\bS^1\times Σ$ corresponding to the extension of Killing horizons by adding points at infinity to the null geodesic forming the horizon. It has been proved that the theory admits a natural representation of $PSL(2,\bR)$ in terms of $*$-automorphisms and this representation is unitarily implementable if referring to a certain invariant state $λ$. Among other results it has been proved that the theory admits a class of inequivalent algebraic (coherent) states $\{λ_ζ\}$, with $ζ\in L^2(Σ)$, which break part of the symmetry, in the sense that each of them is not invariant under the full group $PSL(2,\bR)$ and so there is no unitary representation of whole group $PSL(2,\bR)$ which leaves fixed the cyclic GNS vector. These states, if restricted to suitable portions of $\bM$ are invariant and extremal KMS states with respect a surviving one-parameter group symmetry. In this paper we clarify the nature of symmetry breakdown. We show that, in fact, {\em spontaneous} symmetry breaking occurs in the natural sense of algebraic quantum field theory: if $ζ\neq 0$, there is no unitary representation of whole group $PSL(2,\bR)$ which implements the $*$-automorphism representation of $PSL(2,\bR)$ itself in the GNS representation of $λ_ζ$ (leaving fixed or not the state).

description: We present new spectra obtained using Keck/KCWI and perform kinematics and stellar population analyses of the shell galaxy NGC 474, from both the galaxy centre and a region from the outer shell. We show that both regions have similarly extended star formation histories although with different stellar population properties. The central region of NGC 474 is dominated by intermediate-aged stars (8.3 \pm 0.3 Gyr) with subsolar metallicity ([Z/H]= -0.24 \pm 0.07 dex) while the observed shell region, which hosts a substantial population of younger stars, has a mean luminosity-weighted age of 4.0 \pm 0.5 Gyr with solar metallicities ([Z/H]=-0.03 \pm 0.09 dex). Our results are consistent with a scenario in which NGC 474 experienced a major to intermediate merger with a log\((M_*/M_\odot)\sim10 \) mass satellite galaxy at least \sim 2 Gyr ago which produced its shell system. This work shows that the direct spectroscopic study of low-surface brightness stellar features, such as shells, is now feasible and opens up a new window to understanding galaxy formation and evolution.

Influence of drying processes on the treatability and CCA distribution in the heartwood of five Canadian softwoods
Creators: name: An, Yuxian
Publisher: name: University of British Columbia
Year: 2009

description: The first objective of the study was to determine whether drying could improve the treatability of sawnwood with respect to CCA and borate preservatives. Heartwood boards of lodgepole pine (Pinus contorta Dougl.), white spruce (Picea glauca [Moench.] Voss.), amabilis fir (Abies amabilis [Dougl] Forbes), western hemlock (Tsuga heterophylla Raf. Sarg), and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) were used in this study. The treatability of each board was measured and the boards ranked for permeability. The seven drying processes were: air drying (used as reference), dehumidification drying, conventional drying, presteaming plus conventional drying, high temperature drying, radio frequency/vacuum drying, and superheated steam/vacuum drying. After drying, the boards were pressure treated with either 2.5% CCA or 4.2% disodium octaborate tetrahydrate, and analysed for preservative penetration and retention. It was concluded that: • No single drying regime consistently improved the treatability o f all wood species, for either chemical; • in most cases, CCA and borate preservative penetrations were similar: • for Douglas-fir and western hemlock RF/V drying gave the best penetration for both CCA and borate; The second objective was to examine the microdistribution of the CCA components in different cells of the various softwoods using light microscopy, and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectrometer (EDX). From the visible and SEM - EDX microscopic examination it was found that: the Cu:As:Cr ratio differed markedly for specific analysis locations in treated wood, confirming the different fixation reactions in specific cell types; ray cells, resin canals (if present) and pits played key roles in enhancing CCA penetration in sawnwood; copper and chromium were located in the highly lignified cell corners and compound middle lamellae; arsenic was precipitated in the secondary wall; enhanced copper content was found in the resin canals, suggesting a preferential reaction with extractives; Copper and arsenic concentrations were enhanced in the pit areas; a high concentration o f chromium was found at the crassulae, which is highly lignified; deposits at the tracheid lumens of amabilis fir were shown to contain mainly arsenic and copper.

description: Reformulation of Dirac equation in terms of real quadratic division algebra of quaternions is given. Similar equations with different mass term are identified as suitable for description of free propagating quark motion. The complete orthonormal set of the positive-energy plane wave solutions is presented. Therefore, Zitterbewegung phenomenon is absent in this formulation. The probability current is proportional to the momentum, as in standard Schrodinger wave mechanics.

description: The design and performance of a 1.2 liter liquid xenon chamber equipped with 7 two-inch photomultiplier tubes, with the purpose of studying the scintillation response of xenon to gamma-rays and neutrons, is described. Measurements with gamma-rays indicate a high VUV light collection efficiency resulting in ~5.5 photoelectrons per 1 keV of deposited energy. The energy resolution (FWHM) is 18% and 22%, for 122 keV and 511 keV gamma-rays, respectively. An algorithm for the reconstruction of the scintillation coordinates in (x,y) plane was developed and tested. The position resolution is estimated to be 6.9 mm (sigma) for 122 keV gamma-rays.

description: We study the optical properties of metamaterials made from cut-wire pairs or plate pairs. We obtain a more pronounced optical response for arrays of plate pairs -- a geometry which also eliminates the undesired polarization anisotropy of the cut-wire pairs. The measured optical spectra agree with simulations, revealing negative magnetic permeability in the range of telecommunications wavelengths. Thus, nanoscopic plate pairs might serve as an alternative to the established split-ring resonator design.

description: Optical emission lines are used to categorize galaxies into three groups according to their dominant central radiation source: active galactic nuclei, star formation, or low-ionization (nuclear) emission regions [LI(N)ERs] that may trace ionizing radiation from older stellar populations. Using the Wisconsin H-Alpha Mapper, we detect optical line emission in low-extinction windows within eight degrees of Galactic Center. The emission is associated with the 1.5-kiloparsec-radius "Tilted Disk" of neutral gas. We modify a model of this disk and find that the hydrogen gas observed is at least $48\%$ ionized. The ratio [NII] $λ$6584 $\overset{\lower.5em\circ}{\mathrm{A}}$/H$α$ $λ$6563 $\overset{\lower.5em\circ}{\mathrm{A}}$ increases from 0.3 to 2.5 with Galactocentric radius; [OIII] $λ$5007 $\overset{\lower.5em\circ}{\mathrm{A}}$ and H$β$ $λ$4861 $\overset{\lower.5em\circ}{\mathrm{A}}$ are also sometimes detected. The line ratios for most Tilted Disk sightlines are characteristic of LI(N)ER galaxies.

Evolution of cooperation and consistent personalities in public goods games

description: The evolution of cooperation has remained an important problem in evolutionary theory and social sciences. In this regard, a curious question is why consistent cooperative and defective personalities exist and if they serve a role in the evolution of cooperation? To shed light on these questions, here, I consider a population of individuals who possibly play two consecutive rounds of public goods game, with different enhancement factors. Importantly, individuals have independent strategies in the two rounds. However, their strategy in the first round affects the game they play in the second round. I consider two different scenarios where either only first-round cooperators play a second public goods game, or both first-round cooperators and first-round defectors play a second public goods game, but in different groups. The first scenario can be considered a reward dilemma, and the second can be considered an assortative public goods game but with independent strategies of the individuals in the two rounds. Both models show cooperators can survive either in a fixed point or through different periodic orbits. Interestingly, due to the emergence of a correlation between the strategies of the individuals in the two rounds, individuals develop consistent personalities during the evolution. This, in turn, helps cooperation to flourish. These findings shed new light on the evolution of cooperation and show how consistent cooperative and defective personalities can evolve and play a positive role in solving social dilemmas.

Personalized Explanations

Publisher: name: KIT Scientific Publishing
Year: 2023

description: Machine learning systems are often hard to investigate and intransparent in their decision making . Explainable Artificial Intelligence (XAI) tries to make these systems more transparent. However, most work in the field focuses on technical aspects like maximizing metrics. The human aspects of explainability are often neglected. In this work, we present personalized explanations, which instead focus on the user. Personalized explanations can be adapted to individual users to be as useful and relevant as possible. They can be interacted with to give users the ability to engage in an explanatory dialog with the system. Finally, they should also protect user data to increase the trust in the explanation system.

description: Gas interior to the bar of the Milky Way has recently been shown as the closest example of a Low Ionization (Nuclear) Emission Region--LI(N)ER--in the universe. To better understand the nature of this gas, a sample of face-on galaxies with integral field spectroscopy are used to study the ionized gas conditions of 240 barred and 250 nonbarred galaxies, focusing on those that are most similar to the Milky Way. Strong optical line emission of $[NII]$ $λ6584$, H$α$, $[OIII]$ $λ5007$, and H$β$ are used to diagnose the dominant ionization mechanisms of gas across galaxies and the Galaxy via Baldwin-Phillips-Terlevich (BPT) Diagrams. Barred galaxies show a strong suppression of star formation and an increase in composite and LI(N)ER like spectra in their inner regions when compared with similar nonbarred counterparts. This effect is lessened in galaxies of very low ($\log_{10}(M_\star/M_\odot) \lesssim 10.4$) or very high ($\log_{10}(M_\star/M_\odot) \gtrsim 11.1$) total stellar mass. Bar masks from Galaxy Zoo:3D show the bar's non-axisymmetric effect on the ionized gas and help predict the face-on distribution of ionized gas conditions near the bar of the Milky Way.
