description: Das internationale und interdisziplinäre Forschungsprojekt: „Was hat Europa mit mir zu tun? Europa aus der Sicht von jungen Politiker*innen aus Deutschland und Polen“ wurde in Kooperation der LMU München mit der AMU Posen im Zeitraum von knapp zwei Jahren (April 2019-Dezember 2020) durchgeführt. In diesem Projektbericht wird über den Part der LMU München Auskunft gegeben. Das Projekt war am Lehrstuhl für Didaktik der deutschen Sprache und Literatur der LMU München angesiedelt und verfolgt einen sozialwissenschaftlichen Forschungsansatz. Dabei kamen insbesondere qualitative Forschungsmethoden (vor allem qualitative Interviews verschiedener Art und Weise) zum Einsatz, auf welche im Überblick Methodologie und Methodik genauer eingegangen wird. Im Fokus des Forschungsprojektes stehen junge, politisch engagierte Personen, die einer Partei in Deutschland und Polen angehören und die den Großteil der befragten Personen ausmachen (siehe Sampleübersicht). Weiter wurden Personen aus proeuropäischen Institutionen befragt. Darauf wird in den folgenden Kapiteln detaillierter eingegangen.

description: The high-pressure structural behavior of lanthanum monochalcogenides is investigated by theory and experiment. Theory comprises density functional calculations of LaS, LaSe and LaTe with the general gradient approximation for exchange and correlation effects, as implemented within the full-potential linear muffin-tin orbital method. The experimental studies consist of high-pressure angle dispersive x-ray diffraction investigations of LaS and LaSe up to a maximum pressure of 41 GPa. A structural phase transition from the NaCl type to CsCl type crystal structure is found to occur in all cases. The experimental transition pressures are 27-28 GPa and 19 GPa, for LaS and LaSe, respectively, while the calculated transition pressures are 29 GPa, 21 GPa and 10 GPa for LaS, LaSe and LaTe, respectively. The calculated ground state properties such as equilibrium lattice constant, bulk modulus and its pressure derivative, and Debye temperatures are in good agreement with experimental results. Elastic constants are predicted from the calculations.

description: Eskalationen und Stellvertretungen sind wichtig, um bei der Ausführung von Geschäftsprozessen (GP) auf Ausnahmesituationen reagieren zu können. Hierbei erfordert die Festlegung der jeweils gewünschten Zielperson(en) ähnlich komplexe Regeln, wie die Zuordnung von Aktivitäten zu regulären Bearbeitern. Zusätzlich sind unterschiedliche Regeln für verschiedene Aktivitäten, Originalbearbeiter, etc. erforderlich. Sehr viele solche Regeln zu definieren, würde aber einen großen Aufwand für die GP-Designer bedeuten. Deswegen sollte eine Regel für mehrere Aktivitäten verwendbar sein. Dies wird möglich, indem sie sich auf die reguläre Bearbeiterzuordnung der betroffenen Aktivität beziehen kann, z.B. auf die dort festgelegte Rolle. Da in einer Bearbeiterzuordnung mehrere Rollen gefordert sein können, muss zusätzlich festgelegt werden, welche von diesen referenziert werden soll. Deshalb führen wir für Objekte des Organisationsmodells einen benutzerdefinierbaren SubType ein. Dieser kann bei der Spezifikation der Zielpersonen einer Eskalation oder Stellvertretung verwendet werden, um die gewünschte Rolle auszuwählen. Dadurch wird eine solche Regel für viele unterschiedliche Aktivitäten verwendbar.

description: This work presents an analysis of the effect of the access router buffer size on packet loss rate and how it can affect the QoS of multimedia services when bursty traffic is present. VoIP traffic, real traces of viedoconferencing and videosurvellance are used in two different scenarios with medium link utilization. The study shows that the bursty nature of some applications may impair the MOS of voice calls especially when a certain number of bursts overlap. When link utilization is above 70% good values of VoIP QoS cannot be obtained.

Assessing the cognitive consequences of the object-oriented approach: a survey of empirical research on object-oriented design by individuals and teams

Year: 2006
Subjects: subject: Human-Computer Interaction (cs.HC)
subject: FOS: Computer and information sciences

description: This paper presents a state-of-art review of empirical research on object-oriented (OO) design. Many claims about the cognitive benefits of the OO paradigm have been made by its advocates. These claims concern the ease of designing and reusing software at the individual level as well as the benefits of this paradigm at the team level. Since these claims are cognitive in nature, its seems important to assess them empirically. After a brief presentation of the main concepts of the OO paradigm, the claims about the superiority of OO design are outlined. The core of this paper consists of a review of empirical studies of OOD. We first discuss results concerning OOD by individuals. On the basis of empirical work, we (1) analyse the design activity of novice OO designers, (2) compare OO design with procedural design and, (3) discuss a typology of problems relevant for the OO approach. Then we assess the claims about naturalness and ease of OO design. The next part discusses results on OO software reuse. On the basis of empirical work, we (1) compare reuse in the OO versus procedural paradigm, (2) discuss the potential for OO software reuse and (3) analyse reuse activity in the OO paradigm. Then we assess claims on reusability. The final part reviews empirical work on OO design by teams. We present results on communication, coordination, knowledge dissemination and interactions with clients. Then we assess claims about OOD at the software design team level. In a general conclusion, we discuss the limitations of these studies and give some directions for future research.

description: Optimizing the maintenance of large-scale infrastructure can be a significant cost driver for small and medium-sized enterprises (SMEs). This paper presents a feasible approach to combine data from real-world physical structures collected through an automated maintenance process with cloud-based AI services to generate a meaningful virtual representation of such structures. We use photovoltaic systems as an exemplary physical structure and thermal imaging, collected through scheduled drone monitoring. With help of these unstructured data sources, we demonstrate our approach's applicability. Our solution artifact provides a lightweight AI application that is adoptable for other problem spaces, enabling an easier knowledge transfer from research to SMEs. By combining Cloud Computing with Machine Learning, the artifact identifies present and emerging damages of physical objects. It provides a virtual representation of the object's state and empowers a meaningful visualization.

Anhand einer spieltheoretischen Analyse wird nachvollzogen, wie sich Negativanreize der DSGVO aus Bußgeld- und Haftungsrisiken proaktiv nutzen lassen, um die Motivation datenschutzkonformer Firmen zu stärken, die tendenziell ein höheres Eigeninteresse an der Implementierung geeigneter technischer und organisatorischer Maßnahmen haben. Ökonomische Anreize einer Zertifizierung könnten eine datenschutzfreundliche Technikgestaltung für Unternehmen profitabel machen, wenn sich ein entsprechender Markt etabliert. Für die Unterscheidbarkeit datenschutzfreundlich gestalteter Produkte von Angeboten mit geringem Datenschutzniveau können Zertifikate als Signal gegenüber dem Verbraucher dienen und so eine Grundlage für einen innovationsfördernden Wettbewerb für den Datenschutz durch Technikgestaltung schaffen.

description: As long as learning management systems (LMS) are offering a predefined set of functionalities and could be not flexible enough for changes and improvements. Especially, it could be difficult to enable usage of a new software tool, which is required only by a special teaching curriculum and when change requests are relevant only for a particular course of study. Thus, incorporating innovative technologies into existing learning platforms could be a very challenging task. However, this Problem can be addressed through the latest IT technologies in combination with innovative teaching methodologies. In this work, students are supported in acquiring better hands-on experience using real software in real scenarios. It is done in a way that such scenarios and tools are directly embedded into a teaching curriculum. The introduced modular teaching assistance system helps to simplify installation, configure, and data wrangling phases and enables students to focus on primary tasks, which is solving scenario problems, rather than spend valuable time and deal with software as such. On one hand, the system takes care of various problems with installation and configuration for students, on the other hand, the system is modular and enables adaptation of an innovative teaching experience by being flexible and extensible by design.
Practical Evaluation of Security for Quantum Key Distribution

description: Many papers proved the security of quantum key distribution (QKD) system, in the asymptotic framework. The degree of the security has not been discussed in the finite coding-length framework, sufficiently. However, to guarantee any implemented QKD system requires, it is needed to evaluate a protocol with a finite coding-length. For this purpose, we derive a tight upper bound of the eavesdropper's information. This bound is better than existing bounds. We also obtain the exponential rate of the eavesdropper's information. Further, we approximate our bound by using the normal distribution.

Scale factor point spread function matching: Beyond aliasing in image resampling

description: Imaging devices exploit the Nyquist-Shannon sampling theorem to avoid both aliasing and redundant oversampling by design. Conversely, in medical image resampling, images are considered as continuous functions, are warped by a spatial transformation, and are then sampled on a regular grid. In most cases, the spatial warping changes the frequency characteristics of the continuous function and no special care is taken to ensure that the resampling grid respects the conditions of the sampling theorem. This paper shows that this oversight introduces artefacts, including aliasing, that can lead to important bias in clinical applications. One notable exception to this common practice is when multi-resolution pyramids are constructed, with low-pass "anti-aliasing" filters being applied prior to downsampling. In this work, we illustrate why similar caution is needed when resampling images under general spatial transformations and propose a novel method that is more respectful of the sampling theorem, minimising aliasing and loss of information. We introduce the notion of scale factor point spread function (sfPSF) and employ Gaussian kernels to achieve a computationally tractable resampling scheme that can cope with arbitrary non-linear spatial transformations and grid sizes. Experiments demonstrate significant (p<1e-4) technical and clinical implications of the proposed method.

description: Due to shrinking habitats, moth populations are declining rapidly. An automated moth population monitoring tool is needed to support conservationists in making informed decisions for counteracting this trend. A non-invasive tool would involve the automatic classification of images of moths, a fine-grained recognition problem. Currently, the lack of images annotated by experts is the main hindrance to such a classification model. To understand how to achieve acceptable predictive accuracies, we investigate the effect of differently sized datasets and data acquired from the Internet. We find the use of web data immensely beneficial and observe that few images from the evaluation domain are enough to mitigate the domain shift in web data. Our experiments show that counteracting the domain shift may yield a relative reduction of the error rate of over 60%. Lastly, the effect of label noise in web data and proposed filtering techniques are analyzed and evaluated.

The show is entertaining and educational and is aimed at children aged 10 and older. For the physics students this is a unique experience to apply their knowledge at an early stage and gives them the chance to develop skills in the public presentation of science, in front of 520 people per show. We have extended the activity to put on an elementary particle physics show for teenagers. Furthermore, local high schools have picked up the idea; their students put on similar shows for fellow students and parents. We would be interested in hearing about related activities elsewhere.

description: Two different ab initio potential energy surfaces are employed to investigate the efficiency of the rotational excitation channels for the polar molecular ion HeH$^+$ interacting with He atoms. We further use them to investigate the quantum dynamics of both the proton-exchange reaction and the purely rotational inelastic collisions over a broad range of temperatures. In current modeling studies, this cation is considered to be one of the possible cooling sources under early universe conditions after the recombination era and has recently been found to exist in the Interstellar Medium. Results from the present calculations are able to show the large efficiency of the state-changing channels involving rotational states of this cation. In fact, we find them to be similar in size and behaviour to the inelastic and to the reaction rate coefficients obtained in previous studies where H atoms were employed as projectiles. The same rotational excitation processes, occurring when free electrons are the collision partners of this cation, are also compared with the present findings. The relative importance of the reactive, proton-exchange channel and the purely inelastic channels is also analysed and discussed. The rotational de-excitation processes are also investigated for the cooling kinetics of the present cation under cold trap conditions with He as the buffer gas. The implications of the present results for setting up more comprehensive numerical models to describe the chemical evolution networks in different environments are briefly discussed.

description: We study axially symmetric multi-soliton solutions of a complex scalar field theory with a sextic potential, minimally coupled to Einstein's gravity. These solutions carry no angular momentum and can be classified by the number of nodes of the scalar field, $k_z$, along the symmetry axis; they are interpreted as chains with $k_z+1$ boson stars, bound by gravity, but kept apart by repulsive scalar interactions. Chains with an odd number of constituents show a spiraling behavior for their ADM mass (and Noether charge) in terms of their angular frequency, similarly to a single fundamental boson star, as long as the gravitational coupling is small; for larger coupling, however, the inner part of the spiral is replaced by a merging with the fundamental branch of radially excited spherical boson stars. Chains with an even number of constituents exhibit a truncated spiral pattern, with only two or three branches, ending at a limiting solution with finite values of ADM mass and Noether charge.

description: I review here some of the open questions regarding the geometry and emission mechanisms of galactic black hole candidates. For hard states, I concentrate on the perspective of ``disk+Compton coronae'' models (for discussions of jet models, see the papers by Sera Markoff). Specifically, I discuss the implications from our 10 year long RXTE monitoring campaign of Cyg X-1. I then present simultaneous RXTE/Chandra observations of the ``soft state'' black hole candidate 4U 1957+11, and discuss to what extent it does or does not allow one to test ``relativistic disk models''. The use of such models has been claimed to measure black hole spin parameters. I then briefly present a particularly freaky-weird observation of GX 339-4, where the source ``fell off'' the usual radio/X-ray correlation in the low/hard state. Questions addressed by the above observations include: are the Compton corona models unique fits to the data? (No. Jets work equally well, and simple broken power laws work better still. We argue that the latter models indicate multiple, broad-band continuum components.) Is there good evidence for a receding disk as sources transit into the hard state? (The jury is still out.) What does the relativistically broadened Fe line tell us? (Sometimes the disk, even into quiescence, stays very close to the central object, in contrast to expectations of ADAF models.) How much better/more necessary are recently discussed relativistic disk models? (I am very doubtful that such models will ever usefully measure black hole spin.)

Their combination has not yet been subject of research or research application, nor is there a roadmap to the development of TOspecific AI applications. In relation to permanent organizations, TOs devote more time to organizing, planning, and adapting to change, but supporting organizing as a task is not yet in the scope of AI research. This article creates new links between the domains computer science and organizational theory. It reviews TOs as special vehicles for organizing endeavors, proposes relevant properties, reviews recent AI research advances, and synthesizes challenges for researching into AIassisted organizing in TOs. A table of use cases along with proposed AI methods and required data proposes future research activities and is basis for a call for data sets, data challenges and metrics for assessing AI-assisted organizing, especially in temporary contexts.
Competing with creative transformation : the poetry of Ouyang Xiu (1007-1072)
Creators: name: Hawes, Colin S.C.

description: A detailed study of the poetry (shi R#) of Ouyang Xiu (1007-1072). Though Ouyang Xiu was one of the major cultural figures of the northern Song period (960-1126), later generations have rather neglected his poetry. After a brief introduction explaining this neglect, my study begins with a biographical sketch, outlining Ouyang's public career and concentrating on events that may have shaped his development as a poet. Chapter two deals with Ouyang's poems on mountains, one of his most favoured topics. I describe three kinds of mountain poems: dynamic, forceful works; tranquil works; and those which compare different kinds of mountains in an intellectual manner. Frequently domestic or cultural objects — stone screens, calligraphic rubbings, music — provide the inspiration for Ouyang's mountain poetry. Chapters three and four turn from the "cosmic" level of mountains to the "domestic" world, to discover whether other everyday objects exert a similar effect on his imagination. Chapter three deals with activities: poems on tea and wine drinking; eating; sleeping; music and calligraphy. These works tend to jump back and forth between the mundane and the transcendent, as Ouyang traces each subject to its source in the natural world. Chapter four treats the buildings, gardens, pets and plants in Ouyang's immediate environment. Techniques of caricature and witty argumentation increasingly appear in his mature verse. Water is a central figure in Ouyang's mountain poems. Chapter five reverts to the "cosmic" level to discuss Ouyang's poetry on water in its many transformations: storms, snow, reflected moonlight, rivers and the ocean. In his mature works, Ouyang increasingly mixes levels of discourse — prosaic and lyrical, pure and crude — to indicate the complexity of human reaction to outside events. The concluding chapter summarizes the evolution of Ouyang's poetic style. I define wit, noting its centrality in the English poetic tradition. I carefully analyse Ouyang's recorded comments on poetry: he constantly advocates breadth and variety of mood and subject matter, including even laughter and joking, crudity and baseness. I suggest possible influences on his style, especially Mid-Tang poets like Han Yu and Bai Juyi, and his own contemporary, Mei Yaochen. Finally, I yoke together the concept of wit and Ouyang's phrase "competing with Creative Transformation": like the English witty poets, Ouyang transforms harsh realities into ingenious artistic structures, and finds vitality in the midst of suffering and destruction.

description: This work contributes to the exposure of the current state of environmental disclosure through an empirical transnational study of 344 websites of large production companies from China, Europe, Japan, and the USA. The focus of the investigation is on four formative indices based on variables covering observation of disclosure extent of environmental management and environmental compliance management. All countries show low levels of disclosure. However, some variation on the extent of disclosure was found. The lowest level of disclosure was found for the Chinese websites. Higher - though not remarkable higher - levels of disclosure extents were observed for the companies from Europe, Japan, and the USA. Also, the correlation between disclosure scores based on these observational data and the CDP carbon disclosure scores of the year 2020 did only reveal insignificant correlations. However, websites having webpages containing a higher number of terms of the corporate environmental management terminology also achieve higher CDP scores.
The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere

description: We revisit the hypothesis that there is life in the Venusian clouds to propose a life cycle that resolves the conundrum of how life can persist aloft for hundreds of millions to billions of years. Most discussions of an aerial biosphere in the Venus atmosphere temperate layers never address whether the life-small microbial-type particles-is free floating or confined to the liquid environment inside cloud droplets. We argue that life must reside inside liquid droplets such that it will be protected from a fatal net loss of liquid to the atmosphere, an unavoidable problem for any free-floating microbial life forms. However, the droplet habitat poses a lifetime limitation: Droplets inexorably grow (over a few months) to large enough sizes that are forced by gravity to settle downward to hotter, uninhabitable layers of the Venusian atmosphere. (Droplet fragmentation-which would reduce particle size-does not occur in Venusian atmosphere conditions.) We propose for the first time that the only way life can survive indefinitely is with a life cycle that involves microbial life drying out as liquid droplets evaporate during settling, with the small desiccated 'spores' halting at, and partially populating, the Venus atmosphere stagnant lower haze layer (33-48 km altitude). We, thus, call the Venusian lower haze layer a 'depot' for desiccated microbial life. The spores eventually return to the cloud layer by upward diffusion caused by mixing induced by gravity waves, act as cloud condensation nuclei, and rehydrate for a continued life cycle. We also review the challenges for life in the extremely harsh conditions of the Venusian atmosphere, refuting the notion that the 'habitable' cloud layer has an analogy in any terrestrial environment.

description: We simultaneously observed the Stokes parameters of the photospheric iron line pair at 630.2 nm and the intensity profile of the chromospheric Ca II H line at 396.8 nm in a quiet Sun region at a heliocentric angle of 53 deg. We perform a statistical analysis of network and inter-network properties.The H-index is the integrated emission in a 0.1 nm band around the Ca core. We separate a non-magnetically, H_non, and a magnetically, H_mag, heated component from a non-heated component, H_co in the H-index. The average network and inter-network H-indices are equal to 12 and 10 pm, respectively. The emission in the network is correlated with the magnetic flux density, approaching a value of H 10 pm for vanishing flux. The inter-network magnetic field is dominated by weak field strengths with values down to 200 G and its mean absolute flux density is 11 Mx cm$^{-2}$. We find that a dominant fraction of the calcium emission caused by the heated atmosphere in the magnetic network, has non-magnetic origin (H_mag = 2pm, H_non = 3pm). Considering the effect of straylight, the contribution from an atmosphere with no temperature rise to the H-index (H_co = 6pm) is about half of the observed H-index in the inter-network. The H-index in the inter-network is not correlated to any property of the photospheric magnetic field, suggesting that magnetic flux concentrations have a negligible role in the chromospheric heating in this region. The height range of the thermal coupling between the photosphere and low/mid chromosphere increases in presence of magnetic field. In addition, we demonstrate that a poor signal-to-noise level in the Stokes profiles leads to a significant over-estimation of the magnetic field strength.

description: The initial idea of Robotic Process Automation (RPA) is the automation of business processes through a simple emulation of user input and output by software robots. Hence, it can be assumed that no changes of the used software systems and existing Enterprise Architecture (EA) is required. In this short, practical paper we discuss this assumption based on a real-life implementation project. We show that a successful RPA implementation might require architectural work during analysis, implementation, and migration. As practical paper we focus on exemplary lessons-learned and new questions related to RPA and EA.

description: We find using Monte Carlo simulation the phase structure of noncommutative U(1) gauge theory in two dimensions with the fuzzy sphere S^2_N as a non-perturbative regulator. There are three phases of the model. i) A matrix phase where the theory is essentially SU(N) Yang-Mills reduced to zero dimension . ii) A weak coupling fuzzy sphere phase with constant specific heat and iii) A strong coupling fuzzy sphere phase with non-constant specific heat. The order parameter distinguishing the matrix phase from the sphere phase is the radius of the fuzzy sphere. The three phases meet at a triple point. We also give the theoretical one-loop and 1/N expansion predictions for the transition lines which are in good agreement with the numerical data. A Monte Carlo measurement of the triple point is also given.
