Publisher: name: Zenodo
Year: 2019

description: Within the framework of the REEEM project, this report constitutes deliverable D5.4 Ecosystem Services case study report. This case study of Lithuania was led by the Environmental Management and Assessment (EMA) research group, KTH Royal Institute of Technology, in cooperation with contributors from several institutions, listed below. The case study was included in REEEM Work Package 5 on Environment, Health and Resources, where multiple sustainability goals are addressed for gaining a comprehensive understanding of the systemwide implications of decarbonisation pathways. The case study of Lithuania intended to assess impacts on multiple ecosystem services of forest bioenergy options, as well as to take the first steps for model linking between an ecosystem service assessment tool, and an energy sector development model. In this way, the links between energy assessment and ecosystem services could be strengthened in a more integrated assessment, targeting to increase the sustainability of forest bioenergy strategies.

description: We calculate the current cross-correlation for two weakly interacting mesoscopic conductors. Our derivation is based on the two-particle scattering matrix derived in Goorden and Büttiker [Phys. Rev. Lett. {\bf 99}, 146801 (2007)]. We include the Fermi sea in the leads into the theory and show how to calculate transport quantities and specifically cross-correlations. We focus on the zero-frequency current cross-correlation of two chaotic quantum dots and calculate the magnitude of its fluctuations with the help of Random Matrix Theory.

description: Competing interactions produce finite-size textures in myriad condensed matter systems, typically forming elongated stripe or round bubble domains. Transitions between stripe and bubble phases, driven by field or temperature, are expected to be reversible in nature. Here we report on the distinct character of the analogous transition for nanoscale spin textures in chiral Co/Pt-based multilayer films, known to host Néel skyrmions, using microscopy, magnetometry, and micromagnetic simulations. Upon increasing field, individual stripes fission into multiple skyrmions, and this transition exhibits a macroscopic signature of irreversibility. Crucially, upon field reversal, the skyrmions do not fuse back into stripes, with many skyrmions retaining their morphology down to zero field. Both the macroscopic irreversibility and the microscopic zero-field skyrmion density are governed by the thermodynamic material parameter determining chiral domain stability. These results establish the thermodynamic and microscopic framework underlying ambient skyrmion generation and stability in chiral multilayer films and provide immediate directions for their functionalization in devices.

description: The CNO cycle is the main energy source in stars more massive than our sun, it defines the energy production and the cycle time that lead to the lifetime of massive stars, and it is an important tool for the determination of the age of globular clusters. One of the largest uncertainties in the CNO chain of reactions comes from the uncertainty in the $^{14}$N$(p,γ)^{15}$O reaction rate. This uncertainty arises predominantly from the uncertainty in the lifetime of the sub-threshold state in $^{15}$O at $E_{x}$ = 6792 keV. Previous measurements of this state's lifetime are significantly discrepant. Here, we report on a new lifetime measurement of this state, as well as the excited states in $^{15}$O at $E_{x}$ = 5181 keV and $E_{x}$ = 6172 keV, via the $^{14}$N$(p,γ)^{15}$O reaction at proton energies of $E_{p} = 1020$ keV and $E_{p} = 1570$ keV. The lifetimes have been determined with the Doppler-Shift Attenuation Method (DSAM) with three separate, nitrogen-implanted targets with Mo, Ta, and W backing. We obtained lifetimes from the weighted average of the three measurements, allowing us to account for systematic differences between the backing materials. For the 6792 keV state, we obtained a $τ= 0.6 \pm 0.4$ fs. To provide cross-validation of our method, we measured the known lifetimes of the states at 5181 keV and 6172 keV to be $τ= 7.5 \pm 3.0$ and $τ= 0.7 \pm 0.5$ fs, respectively, which are in good agreement with previous measurements.

description: In this paper we discuss the asymptotic spectrum of the spin chain description of planar N=4 SUSY Yang-Mills. The states appearing in the spectrum belong to irreducible representations of the unbroken supersymmetry SU(2|2) x SU(2|2) with non-trivial extra central extensions. The elementary magnon corresponds to the bifundamental representation while boundstates of Q magnons form a certain short representation of dimension 16Q^{2}. Generalising the Beisert's analysis of the Q=1 case, we derive the exact dispersion relation for these states by purely group theoretic means.

description: Evaluation studies are essential for determining the utilization of technology-enhanced learning systems. Prior research often focuses on evaluating specific factors like the technology adoption or usability aspects. However, it needs to be questioned if evaluating only specific factors is appropriate in each case. The aim of this research paper is to outline which methods are suited for evaluating technology-enhanced learning systems in interdisciplinary research domains. Specifically, we focus our analysis on pedagogical conversational agents – i.e. learning systems that interact with learners using natural language. For instance, in addition to technology acceptance, further factors like learning success are more important in this case. Based on this assumption, we analyze the current state-of-the-art literature of pedagogical conversational agents to identify evaluation objectives, procedures and measuring instruments. Afterward, we use the results to propose a guideline for evaluations of pedagogical conversational agents.

description: In the present paper, we continue to study the two-dimensional soliton system that is composed of vortex and Q-ball components interacting with each other through an Abelian gauge field. This vortex-Q-ball system is electrically neutral as a whole, nevertheless it possesses a nonzero electric field. Moreover, the vortex-Q-ball system has a quantized magnetic flux and a nonzero angular momentum, and combines properties of topological and nontopological solitons. We investigate radially and azimuthally excited states of the vortex-Q-ball system along with the unexcited vortex-Q-ball system at different values of gauge coupling constants. We also ascertain the behaviour of the vortex-Q-ball system in several extreme regimes, including thin-wall and thick-wall regimes.

description: Unter Gamification wird die Anwendung von Spielprinzipien auf reale Kontexte verstanden. Der Begriff Deep Gamification wird verwendet, wenn die Prozesse realer Kontexte strukturell durch Gamification verändert werden. Deep Gamification führt dazu, dass die Nutzer in die Lage versetzt werden, die Prozesse gemäß persönlichen Präferenzen anzupassen. Im Vergleich zu Gamification wird davon ausgegangen, dass Deep Gamification eine stärkere Wirkung auf die Motivation der Nutzer hat. Bislang gibt es jedoch keinen umfassenden konstruktiven Rahmen – im Sinne von Gestaltungsrichtlinien – für die Integration von Deep Gamification in didaktische Kontexte. Dieser Artikel untersucht die Self-Determination Theory (SDT) als Grundlage eines konstruktiven Rahmens für die Integration von Deep Gamification in didaktische Kontexte. Eine Fallstudie, die außergewöhnlich hohe Lernaktivitäten der Studierenden zeigt, weist Merkmale von Deep Gamification auf und dient als Ausgangsbasis. Die Anwendbarkeit der SDT wird durch einen Abgleich mit den Gamification-Elementen der Fallstudie gezeigt.

Spin polarization decay in spin-1/2 and spin-3/2 systems

description: We present a general unifying theory for spin polarization decay due to the interplay of spin precession and momentum scattering that is applicable to both spin-1/2 electrons and spin-3/2 holes. Our theory allows us to identify and characterize a wide range of qualitatively different regimes. For strong momentum scattering or slow spin precession we recover the D'yakonov-Perel result, according to which the spin relaxation time is inversely proportional to the momentum relaxation time. On the other hand, we find that, in the ballistic regime the carrier spin polarization shows a very different qualitative behavior. In systems with isotropic spin splitting the spin polarization can oscillate indefinitely, while in systems with anisotropic spin splitting the spin polarization is reduced by spin dephasing, which is non-exponential and may result in an incomplete decay of the spin polarization. For weak momentum scattering or fast spin precession, the oscillations or non-exponential spin dephasing are modulated by an exponential envelope proportional to the momentum relaxation time. Nevertheless, even in this case in certain systems a fraction of the spin polarization may survive at long times. Finally it is shown that, despite the qualitatively different nature of spin precession in the valence band, spin polarization decay in spin-3/2 hole systems has many similarities to its counterpart in spin-1/2 electron systems.

Star Formation in Splash Bridges

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Splash bridges are created from the direct collision of two gas-rich disk galaxies. These direct collisions can eject gas masses on the order of \SI{e10} Msun stripped from the stellar disks of each galaxy. The Taffy Galaxy system (UGC 1294/5) is a prototypical example of a splash bridge system. CO observations of the Taffy revealed that its splash bridge contains a mass of H_2 equal to that of the Milky Way's H_2 mass. However, the little visible star formation occurring within the bridge highlights the need for models of direct gas-rich disk collisions. The Arp 194 system displays what may be another splash bridge resulting from the collision between two disk galaxies. The region between the two stellar disks contains bright clumps of active star formation. We aim to better understand the conditions for star formation in splash bridges by employing a Jeans criterion to determine where gravitational instabilities occur in the shocked and cooling gas of gas-rich disk collisions. The splash bridge results are obtained from our previous work using a sticky particle code and post-processed. We find that the inclination between the gas disks and the collision velocity with which the gas collides strongly affects the fraction of gas that will become gravitationally unstable. Low inclinations between gas disks produce starbursts whereas high inclinations result in steady-rate star formation. The offset of the gas disks at impact will determine how many gas elements directly collide but does not strongly affect the resulting star formation.

description: Recent advances in sensor technology allow for investigating emotional and cognitive states of learners. However, making use of sensor data is a complex endeavor, even more so when considering physiological data to support learning. In the BMBF-funded project Learning Analytics for sensor-based adaptive learning (LISA), we developed a comprehensive solution for adaptive learning using sensor data for acquiring skin conductance, heart rate, as well as environmental factors (e.g. CO2). In particular, we developed, (i) a sensor wristband acquiring physiological and environmental data, (ii) a tablet application (SmartMonitor) for monitoring and visualizing sensor data, (iii) a learning analytics backend, which processes and stores sensor data obtained from SmartMonitor, and (iv) learning applications utilizing these features. In an ongoing study, we applied our solution to a serious game to adaptively control its difficulty. Post-hoc interviews indicated that learners became aware of the adaptation and rated the adaptive version better and more exciting. Although potentials of utilizing physiological data for learning analytics are very promising, more interdisciplinary research is necessary to exploit these for real-world educational settings.

description: We aim to characterise the morphology and the physical parameters governing the shock physics of the Herbig-Haro object HH99B. We have obtained SINFONI-SPIFFI IFU spectroscopy between 1.10 and 2.45 um detecting more than 170 emission lines, Most of them come from ro-vibrational transitions of H_2 and [FeII]. All the brightest lines appear resolved in velocity. Intensity ratios of ionic lines have been compared with predictions of NLTE models to derive bi-dimensional maps of extinction and electron density, along with estimates of temperature, fractional ionisation and atomic hydrogen post-shock density. H_2 line intensities have been interpreted in the framework of Boltzmann diagrams, from which we have derived maps of extinction and temperature of the molecular gas. From the intensity maps of bright lines the kinematical properties of the shock(s) at work in the region have been delineated. Finally, from selected [FeII] lines, constraints on the spontaneous emission coefficients of the 1.257, 1.321 and 1.644 um lines are provided. The kinematical properties derived for the molecular gas substantially confirm those published in Davis et al.(1999), while new information (e.g. v_shock ~115 km s^-1 is provided for the shock component responsible for the ionic emission. We also provide an indirect measure of the H_2 breakdown speed (between 70 and 90 km s^-1) and compute the inclination angle with respect to the line of sight. The map parameters, along with images of the observed line intensities, will be used to put stringent constraints on up-to-date shock models.

description: Neutrino telescopes are moving steadily toward the goal of detecting astrophysical neutrinos from the most powerful galactic and extragalactic sources. Here we describe analysis methods to search for high energy point-like neutrino sources using detectors deep in the ice or sea. We simulate an ideal cubic kilometer detector based on real world performance of existing detectors such as AMANDA, IceCube, and ANTARES. An unbinned likelihood ratio method is applied, making use of the point spread function and energy distribution of simulated neutrino signal events to separate them from the background of atmospheric neutrinos produced by cosmic ray showers. The unbinned point source analyses are shown to perform better than binned searches and, depending on the source spectral index, the use of energy information is shown to improve discovery potential by almost a factor of two.

From aboriginality to governmentality : the meaning of section 35(1) and the power of legal discourse
Creators: name: Hannigan, David
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines recent doctrinal developments regarding the aboriginal and treaty rights which are recognised and affirmed in s.35(l) of the Constitution Act, 1982. Specifically, it explores how the meaning of such rights is being constituted by diverse relations of power operating within specific 'cites' of struggle. Chapter I is a brief introduction to recent transformations in the legal discourse of the Supreme Court and an overview of the methodologies being employed in this thesis. In this regard, the author undertakes an interdisciplinary approach to discourse analysis. Chapter II draws upon the writings of Michel Foucault to make the argument for the analytical framework being utilised; namely, the study of 'law' within a 'sovereign- discipline- government' society. Chapter III examines the relationship between the productive power of the disciplines and the legal discourse constituting the content of aboriginal rights; the purpose being to explore to what extent law 'operates as a norm' within this area. Additionally, it provides a lead into the discussion of 'government' by outlining the rationality underpinning the test for the justified governmental infringement of aboriginal and treaty rights. Chapter IV, examines the relationship between the regulatory power of 'government' and the legal discourse around current treaty negotiations. Specifically, it explores the inter-dependency between rationalities of self-government and the governmental technologies associated with 'advanced' liberalism. In doing so, it focuses on an emerging treaty from British Columbia to assess the extent to which law is being used as 'a tactic of government'. Chapter V, examines the relationship between the deductive power of 'sovereignty' and the legal discourse constituting the content of Aboriginal title. It argues that recent developments require the Court to deal with the issue of legal pluralism. And to do so, in a way that lays a more successful foundation in law for the legitimate reconciling of the pre-existence of First Nations societies and the sovereignty of the Crown. Chapter VI provides some concluding comments about the insights gained from the proceeding analysis. In doing so, it offers a brief discussion of how the proceeding specific analysis may relate to some recent work in post-colonial studies.

Dadurch soll es Studierenden und Lehrenden erleichtert werden, Relationen zwischen den Lehrveranstaltungen zu entdecken. Um dieses Ziel zu erreichen, wurde exemplarisch ein vollständiger Satz von 572 Studienbriefen der Fakultät für Mathematik und Informatik der FernUniversität in Hagen als Document Embeddings vektorisiert und anschließend über die Kosinusähnlichkeit der Vektoren verglichen. Der gesamte Prozess kommt dabei ohne gelabelte Daten aus. Das Ergebnis der Analyse weist eine hohe Pearson’s Korrelation zu einem von Domänenexperten ermittelten Goldstandard auf. Die Anwendungsmöglichkeiten dieser Ergebnisse werden am Beispiel eines Empfehlungssystem, eines Learning Dashboard für Lehrende und in einer Komponente einer adaptiven Lernumgebung demonstriert.

description: Electromagnetic properties of a simple polarisable medium may be parameterised in terms of a constitutive tensor whose properties can in principle be determined by experiments in non-inertial (accelerating) frames and in the presence of weak but variable gravitational fields. After establishing some geometric notation, discussion is given to basic concepts of stress, energy and momentum in the vacuum where the useful notion of a drive form is introduced in order to associate the conservation of currents involving the flux of energy, momentum and angular momentum with spacetime isometries. The definition of the stress-energy-momentum tensor is discussed with particular reference to its symmetry based on its role as a source of relativistic gravitation. General constitutive properties of material continua are formulated in terms of spacetime tensors including those that describe magneto-electric phenomena in moving media. This leads to a formulation of a self-adjoint constitutive tensor describing, in general, inhomogeneous, anisotropic, magneto-electric bulk matter in arbitrary motion. The question of an invariant characterisation of intrinsically magneto-electric media is explored. An action principle is established to generate the phenomenological Maxwell system and the use of variational derivatives to calculate stress-energy-momentum tensors is discussed in some detail. The relation of this result to tensors proposed by Abraham and others is discussed in the concluding section where the relevance of the whole approach to experiments on matter in non-inertial environments with variable gravitational and electromagnetic fields is stressed.

description: Digitalization confronts vocational education and training (VET) with both challenges and potentials. However, concrete effects of digitalization are missing in research. Especially the perspective of training and learning departments seems to be interesting because the employees in these areas are the central actors in imparting the necessary competencies and skills to the employees of enterprises. Therefore, the main goal of this paper is to elaborate effects of digitalization on VET from the above-mentioned perspective. To reach this goal, we conducted a qualitative study by interviewing 20 experts of enterprise training and identified two main effects on VET.

description: Prisoner's dilemma game is the most commonly used model of spatial evolutionary game which is considered as a paradigm to portray competition among selfish individuals. In recent years, Win-Stay-Lose-Learn, a strategy updating rule base on aspiration, has been proved to be an effective model to promote cooperation in spatial prisoner's dilemma game, which leads aspiration to receive lots of attention. But in many research the assumption that individual's aspiration is fixed is inconsistent with recent results from psychology. In this paper, according to Expected Value Theory and Achievement Motivation Theory, we propose a dynamic aspiration model based on Win-Stay-Lose-Learn rule in which individual's aspiration is inspired by its payoff. It is found that dynamic aspiration has a significant impact on the evolution process, and different initial aspirations lead to different results, which are called Stable Coexistence under Low Aspiration, Dependent Coexistence under Moderate aspiration and Defection Explosion under High Aspiration respectively. Furthermore, a deep analysis is performed on the local structures which cause cooperator's existence or defector's expansion, and the evolution process for different parameters including strategy and aspiration. As a result, the intrinsic structures leading to defectors' expansion and cooperators' survival are achieved for different evolution process, which provides a penetrating understanding of the evolution. Compared to fixed aspiration model, dynamic aspiration introduces a more satisfactory explanation on population evolution laws and can promote deeper comprehension for the principle of prisoner's dilemma.

description: Lernende mit sonderpädagogischem Förderbedarf oder persistierenden Lernstörungen können in Schule und Ausbildung vor besonderen Herausforderungen stehen. Am Beispiel der Ausbildung in der Bauindustrie wird ein Konzept zur Unterstützung von Auszubildenden entwickelt. Am konkreten Fallbeispiel des Mauerwerksbaus sollen mobile Lernapplikationen mithilfe eines Cross-Plattform-Ansatzes entwickelt werden. Innerhalb der Aufgaben, die in der Lernapplikation bearbeitet werden können, werden Hilfetools ansetzen, um die Lernenden bei der Lösung der Aufgaben zu unterstützen. Im Sinne der Inklusion sollen individuelle Hilfestellungen möglich sein und Richtlinien zur barrierefreien Entwicklung berücksichtigt werden.

description: We present a comparison between the 2001 XMM-Newton and 2005 Suzaku observations of the quasar, PG1211+143 at z=0.0809. Variability is observed in the 7 keV iron K-shell absorption line (at 7.6 keV in the quasar frame), which is significantly weaker in 2005 than during the 2001 XMM-Newton observation. From a recombination timescale of <4 years, this implies an absorber density n>0.004 particles/cm3, while the absorber column is 5e22

description: Viele Positionen im Informatiksektor können schon heute nicht besetzt werden und es ist davon auszugehen, dass dieser Mangel an Informatiker*innen in Zukunft noch steigen wird. Problematisch ist dabei auch die hohe Abbrecherquote in den entsprechenden Studiengängen. Viele Themen des Studiums erscheinen als zu theoretisch, abstrakt oder nicht praxisrelevant. Es stellt sich daher die Frage, wie Lerninhalte adäquater vermittelt und mehr Schüler*innen für Themen der Informatik begeistert werden können. Als Mittel zur Steigerung der Motivation scheinen besonders Spiele geeignet. Der vorliegende Aufsatz soll daher folgende Frage beantworten: Können mithilfe eines Serious Games basierten Lernsystems Motivation und Lernerfolg für grundlegende Programmierkenntnisse gesteigert werden?

description: Technologies play an important role in the hiring process for software professionals. Within this process, several studies revealed misconceptions and bad practices which lead to suboptimal recruitment experiences. In the same context, grey literature anecdotally coined the term Résumé-Driven Development (RDD), a phenomenon describing the overemphasis of trending technologies in both job offerings and resumes as an interaction between employers and applicants. While RDD has been sporadically mentioned in books and online discussions, there are so far no scientific studies on the topic, despite its potential negative consequences. We therefore empirically investigated this phenomenon by surveying 591 software professionals in both hiring (130) and technical (558) roles and identified RDD facets in substantial parts of our sample: 60% of our hiring professionals agreed that trends influence their job offerings, while 82% of our software professionals believed that using trending technologies in their daily work makes them more attractive for prospective employers. Grounded in the survey results, we conceptualize a theory to frame and explain Résumé-Driven Development. Finally, we discuss influencing factors and consequences and propose a definition of the term. Our contribution provides a foundation for future research and raises awareness for a potentially systemic trend that may broadly affect the software industry.

description: We study a Lorentz invariant pairing mechanism that arises when two relativistic spin-1/2 fermions are subjected to a Dirac string coupling. In the weak coupling regime, we find remarkable analogies between this relativistic bound system and the well known superconducting Cooper pair. As the coupling strength is raised, quenched phonons become unfrozen and dynamically contribute to the gluing mechanism, which translates into novel features of this relativistic superconducting pair.

description: The HERA experiments have collected interesting luminosity samples with both polarized and unpolarized lepton beams. The polarized CC data are directly sensitive to right handed charged currents. The data are in agreement with the SM predicting their absence. Effects of Z-exchange have been seen in the lepton beam charge and polarization assymetries. A combined electroweak and QCD analysis allows one to measure electroweak parameters with world competitive accuracy.

description: Im Rahmen des BMBF-geförderten Projektes „Machine Learning Campus Minden“ wurde ein Lehr- und Lernkonzept entwickelt, um den Schwerpunkt Maschinelles Lernen (ML) im Curriculum des Masterstudiengangs Informatik der Fachhochschule Bielefeld auszubauen. Dazu wird das Grundlagenmodul “Methoden des Maschinellen Lernens” zur Vermittlung des theoretischen Basiswissens angeboten. Darauf aufbauend können die Studierenden ihre Kenntnisse in einer Reihe von anwendungsorientierten Vertiefungsmodulen wie beispielsweise “Natural Language Processing” (NLP) oder “Data Science“ (DS) an Fragestellungen aus dem Forschungs- und Industriealltag erproben und erweitern. Um eine praxisnahe Ausbildung auf dem aktuellen technologischen Stand zu gewährleisten, bieten alle neuen Module die praktische Anwendung mittels modernen Cloud-Plattformen an. In diesem Beitrag wird das so entstandene Lehr- und Lernkonzept vorgestellt. Außerdem stellen wir die gesammelten Erfahrungen bei der Integration von Infrastructure-as-a-Service-Diensten in der Lehre dar und gehen sowohl auf die fachlichen als auch organisatorischen Anforderungen und Fallstricke ein sowie auf die Evaluation der eingesetzten Cloud-Anbieter in Hinblick auf die domänenspezifischen und praxisrelevanten Probleme.

description: Digitalisierung ist, nicht nur im Bildungsbereich, in aller Munde: sie wird einerseits sehr positiv in Bezug auf neue Lehr-Lernmöglichkeiten und Teilhabe-Chancen diskutiert, andererseits auch stark in punkto Überwachung und Kontrolle kritisiert. Leugnen kann sie jedoch niemand. An den Hochschulen sind bereits viele Akteure mit der Digitalisierung der Hochschul(lehr)e befasst. Weitere werden durch Fördersummen in den kommenden Jahren hinzukommen. Wie sich die Digitalisierung dann tatsächlich ausgestaltet, wird ein spannender Prozess. Öffentliche Diskurse prägen dabei die Diskussionen mit, die an Hochschulen stattfinden. So sind die warnenden Stimmen genauso laut, wie diejenigen, die kritiklos(er) an die Thematik herangehen. Doch weder sozial- noch technikdeterministische Argumentationen werden langfristig die Diskussionen und Prozesse voranbringen. Die Betrachtung aller Akteure und ihre Verwicklungen in Netzwerken ist ein vielversprechender Schlüssel für eine aktive Mitgestaltung.
