3A563571187.jsonld | On the analysis tools of turbulent and financial time series | The aim of this work is to give a review on some of the important tools used in analyzing time series. Since turbulence turned out to be a rather complex phenomenon, a variety of different models and analysis tools have been devised to simulate, analyze and address the different questions that are raised by the behaviour of these seemingly very erratic, highly chaotic time series that are gained from the natural phenomena or the models that are supposed to simulate these processes whether natural, financial, ... etc. The most part of the work was dedicated to the stationary time series which are gained from laboratory controlled turbulence experiments, for example, or the models that simulate them e.g. the direct numerical simulation. The main models that were dealt with are the large eddy simulation (LES) and the diffusion equation which is a simplified version of the Navier-Stokes equations (NSE). Then there are tools that are used to extract different information from the time series, like the dimensions, e.g. embedding, fractal, correlation, and the statistical tools like the spectrum, autocorrelation, scaling of the structure function. We have shown that these tools do not say a lot about non-stationary time series and that there are another set of tools e.g. the spectrogram, Wigner-Ville spectrum, wavelets, that define more clearly events that have a beginning and an end but the full interpretation of their results needs more research. <engl.> Das Ziel dieser Arbeit ist es, einen Überblick über einige der wichtigsten Instrumente zur Analyse von turbulenten Zeitreihen zu geben. Turbulenz erwies sich bisher als ein recht komplexes Phänomen. Daher sind eine Vielzahl von verschiedenen Modellen und Analysemethoden entwickelt worden. Mit ihrer Hilfe werden die verschiedenen Fragen bearbeitet, die sich aus dem Verhalten der scheinbar sehr sprunghaften, hoch chaotischen Zeitreihen stellen, die von natürlichen Phänomenen oder aus der Modellsimulation solcher Prozesse (natürliche Prozesse, Finanzdaten, usw.) stammen. Die vorliegende Arbeit widmet sich vor allem der Analyse stationärer Zeitreihen aus kontrollierten Turbulenzexperimenten im Labor bzw. den dazugehörigen Modellsimulationen (z.B. direkte numerische Simulation). Die wichtigsten Modelle welche behandelt werden sind die Large Eddy Simulation (LES) und die Diffusions-Gleichung, eine vereinfachte Version der Navier-Stokes-Gleichungen (NSE). Es werden außerdem Analysewerkzeuge vorgestellt, mit deren Hilfe man verschiedene Informationen aus den Zeitreihen extrahieren kann. Beispiele sind die Dimensionen, wie etwa Einbettung, Fraktale, und Korrelation oder statistische Datenanalyse wie Spektrum, Autokorrelation und Skalierung der Struktur-Funktion. In der Arbeit wird gezeigt, dass diese Methoden über instationäre Zeitreihen wenig aussagen, dass es jedoch eine Reihe anderer Methoden wie z.B. das Spektrogramm, das Wigner-Ville-Spektrum oder Wavelets gibt, welche Ereignisse, die einen Anfang und ein Ende haben, klarer beschreiben können. Die vollständige Interpretation ihrer Ergebnisse verlangt jedoch noch weitere Untersuchungen. <dt.> |

3A1655507788.jsonld | Equality Governance via Policy Analysis? : The Implementation of Gender Impact Assessment in the European Union and Gender-based Analysis in Canada | Gender impact assessment has been both celebrated as a beacon of hope for the cause of gender equality and criticised as being ineffectual. More than 20 years of gender mainstreaming have demonstrated that equality governance with and through impact assessment is an intersectional and still evolving process.Arn T. Sauer's study examines the instruments of gendered policy analysis and the conditions under which they are being used by the Canadian federal government and the European Commission. Interviews with experts from public administration and instrument designers as well as document analyses reveal benefits and challenges and show that the success of equality governance depends upon whether knowledge about gendered policy and appropriate administrative practices are embedded, embodied and entrenched in public administration. |

This pioneering work provides an overview of the development of German transnational education (TNE) between 1990 and 2016. To explain changes in German TNB, it analyses the steering and coordination activities of relevant state and quasi-state actors, while highlighting inter-ministerial conflicts over responsibilities and resources. The study shows that German TNE has become increasingly politicised over time, i.e. that its projects have been embedded in a growing number of strategies aimed at aiding Germany’s foreign, higher education and development policies. Warum und wie beteiligen sich deutsche Bundesministerien und ihre Mittler- und Durchführungsorganisationen an Aufbau und Betrieb deutscher Hochschulprojekte im Ausland? Die Pionierarbeit gibt einen Überblicküber die Entwicklung der deutschen transnationalen Bildung (TNB) zwischen 1990 und 2016. Zur Erklärung des Wandels der deutschen TNB werden Steuerungs- und Koordinationsaktivitäten der relevanten staatlichen und quasi-staatlichen Akteure analysiert und interministerielle Konflikte um Kompetenzen und Ressourcensichtbargemacht. Dabei wird gezeigt, wie die deutsche TNB im Zeitverlauf immer weiter politisiert, also in eine steigende Anzahl an Strategien der deutschen Außen-, Hochschul- und Entwicklungspolitik eingebettet wurde. |
3A1750143976.jsonld | Development of scale-bridging approaches for the simulation of proton conduction and intermolecular interactions : [kumulative Dissertation] | ab initio molecular dynamics simulation, proton conduction, Markov model, multiscale approach, linear density-density response function, electronic structure This thesis deals with the development of scale-bridging methods for the simulation of proton conduction and an efficient approach for the calculation of inter-molecular electrostatic interactions. In this thesis ab initio molecular dynamics simulations of the solid acid family CsHyXO4 (X= S, P, Se, y = 1, 2) were performed. The resulting trajectories are utilized to derive the Molecular Dynamics/Matrix Propagation (MDM) method, which condenses the dynamic information on proton transport within an entire molecular dynamics simulation into an M x M matrix where M is the number of oxygen atoms. The MDM approach is used to explicitly compute proton dynamics in CsH2PO4 on the micrometer length scale and in a nanoporous network in agreement with experimental results. The second part of this thesis is dedicated to the investigation of lowdimensional representations of the linear density-density response function (LDDRF). The efficient representation of the LDDRF can be used to incorporate polarization effects into a classical molecular dynamics simulation. Gegenstand dieser Arbeit ist die Entwicklung einer skalenübergreifenden Methode zur Beschreibung von Protonenleitung und eines effizienten Ansatzes zur Berechnung von intermolekularen elektrostatischen Wechselwirkungen. Im Rahmen dieser Arbeit wurden ab initio Molekulardynamik-Simulationen von Verbindungen des Typs CsHyXO4 (X= S, P, Se, y = 1, 2) durchgeführt. Die resultierenden Trajektorien wurden dazu genutzt, die Molecular Dynamics/Matrix Propagation (MDM) Methode zu entwickeln, welche die Protonendynamik einer kompletten Molekulardynamik-Simulation in einer M x M Matrix kondensiert, wobei M die Anzahl der Sauerstoffatome beschreibt. Der MDM Ansatz wurde dazu benutzt, die Protonendynamik in einem CsH2PO4 System auf einer Längenskala von einigen Mikrometern und in einem nanoporösen Netzwerk in Übereinstimmung mit experimentellen Daten zu simulieren. Der zweite Teil dieser Arbeit widmet sich der Untersuchung einer niedrig dimensionalen Darstellung der linear density-density response function (LDDRF). Mithilfe der effizienten Darstellung der LDDRF können Polarisationseffekte in klassischen Molekulardynamik-Simulation berücksichtigt werden. ab initio Molekulardynamik-Simulation, Protonenleitung, Markov-Modell, Multiskalen-Ansatz, linear density-density response function, Elektronenstruktur |

3A501734740.jsonld | Function spaces with dominating mixed smoothness | We study several techniques which are well known in the case of Besov and TriebelLizorkin spaces and extend them to spaces with dominating mixed smoothness. We use the ideas of Triebel to prove three important decomposition theorems. We deal withsocalled atomic, subatomic and wavelet decompositions. All these theorems have much in common. fRoughly speaking, they say that a function belongs to some function space if, and only if, it can be decomposed into the sum of products of coefficients and corresponding building blocks, where the coefficients belong to an appropriate sequence space. These decomposition theorems estabilisha veryusefulconnection between function and sequence spaces. We use them in the study of the decay of entropy numbers of compact embeddings between two function spaces of dominating mixed smoothness reducingthis problem to the same question on the sequence space level. The considered scales cover many important specific spaces (Sobolev, Zygmund, Besov) and we get generalisations of respective assertions of Belinsky, Dinh Dung and Temlyakov. |

3A859728676.jsonld | Simulation of continuous-wave solid-state laser resonators using field tracing and a fully vectorial fox-li algorithm | In this PHD thesis the scalar Fox and Li algorithm for the dominant transversal resonator eigenmode calculation is generalized to a fully vectorial field tracing concept. Therefore Fox and Li’s scalar integral equation is reformulated to a set of coupled operator equations. The introduction of a field tracing round trip operator concept shows that, in principle, any modeling technique which can be formulated to operate for electromagnetic fields can be used to simulate light propagation through the different subdomains of the resonator. This allows a flexible, fast, and accurate simulation of the fully vectorial dominant transversal resonator eigenmode. Several examples are presented to demonstrate the flexibility and accuracy of the field tracing approach. |

3A66563384X.jsonld | Theoretische Untersuchungen zur Struktur und zum Reaktionmechanismus der Schweineleberesterase und ihrer Isoenzyme | Theoretical investigations on seven different isoenzymes of the pig liver esterase were made. Prediction on the structure with force field methods (AMBER) were executed. The reactional mechanism was simulated with quantum chemical (CPMD) and hybrid methods (QM/MM). Because there's no crystal structure available yet, a homology model was used. Simulation time of the monomers (around 8000 atoms + around 40000 molecules of water) were 8 to 10 ns. As result stable 3D-structures were found. Unfolding of entrance helices in PLE3 and folding of 3-10 helices were obtained. Also a stable structure of a trimer of PLE1 (nearly 24000 atoms + around 50000 water molecules) was found with interactions between the monomers. With RMSD-analysis, flexible and rifid regions were found. The rigid parts are conform to the a/b-hydrolase fold schemata. Specific distances in the active site were measured, whereby a new Glu was identified as possible member of the catalytic triade. The complete reaction mechanism was reproduced on the example of the cleavage of a molecule methylbutyrate.

This established practice is perceived differently by social interest groups and is quite controversial.This dissertation therefore examines what steps should be taken by the deaconry to justify the sole legal use of temporary corporate employment to those interest groups. On this basis, a value-oriented (and ideal) concept for temporary corporate employment is developed, in which relevant criteria, core building blocks, tools and measures are included. Um den niedrigen öffentlichen Refinanzierungen der sozialen Arbeit, dem politisch gewollten Wettbewerb (Wohlfahrtsverbände untereinander sowie mit freigewerblichen Anbietern) und der Trägerpluralität entgegenwirken zu können, nutzen viele diakonische Träger das Instrumentarium der konzerneigenen Zeitarbeit. Diese gelebte Praxis wird von den gesellschaftlichen Interessengruppen unterschiedlich wahrgenommen und ist teilweise nicht unumstritten.In der Dissertation wird daher untersucht, welche Anstrengungen von der Diakonie unternommen werden sollten, um die konzerneigene Zeitarbeit über die bloße legale Anwendung hinaus bei den Interessengruppen zu rechtfertigen. Auf dieser Grundlage wird ein werteorientiertes (Ideal-)Konzept für die keZA entwickelt, das relevante Kriterien, Kernbausteine sowie Instrumente und Maßnahmen beinhaltet. |

3A1692255797.jsonld | Die Pflicht zum Schulbesuch : zur Frage nach einem Recht auf Homeschooling unter Berücksichtigung grundrechtlicher Freiheiten von Eltern und Schülern | The author discusses the constitutional conformity of compulsory schooling and the question of whether parents or pupils have a right to homeschooling – i.e. a right to replace school attendance with other education at home. In her opinion, Article 7 of the German constitution assumes a general obligation to attend school, which results from the regulations on religious education and freedom of private schooling, as well as from the history of the norm. The factual legitimacy of compulsory schooling lies in its democratisation and integration function. The fundamental rights of parents and children do not require the admission of homeschooling either. As fundamental rights affected by compulsory schooling, the author cites the parental right of education and, on the part of the pupils, the general freedom of action, the general right of personality and the freedom of the person. Furthermore, the author deals with the protection of fundamental rights in cases of religiously motivated homeschooling. Die Autorin erörtert die Verfassungskonformität der Schulpflicht und die Frage, ob Eltern bzw. Schülern ein Recht auf Homeschooling zusteht – also ein Recht darauf, den Schulbesuch durch anderweitigen Unterricht zuhause zu ersetzen. Ihrer Ansicht nach geht das Grundgesetz in Art. 7 von einer allgemeinen Schulpflicht aus, was sich aus den Regelungen zum Religionsunterricht und der Privatschulfreiheit sowie aus der Entstehungsgeschichte der Norm ergibt. Ihre sachliche Legitimation findet die Schulpflicht in ihrer Demokratisierungs- und Integrationsfunktion. Auch die Grundrechte von Eltern und Kindern gebieten nicht die Zulassung von Homeschooling. Als von der Schulpflicht betroffene Grundrechte führt die Autorin das elterliche Erziehungsrecht an sowie auf Seiten der Schüler die allgemeine Handlungsfreiheit, das allgemeine Persönlichkeitsrecht und die Freiheit der Person. Weiterhin geht die Autorin auf den grundrechtlichen Schutz in Fällen des religiös motivierten Homeschooling ein. Die Arbeit wurde von der Universität zu Köln mit dem Promotionspreis 2019 der Fakultät ausgezeichnet. |
3A718869109.jsonld | Hölderlin: critique de la raison et habitation poétique de l'homme | How does Hölderlin's critique of reason open up the possibility of a poetical dwelling of man on earth? What is the role of poetical language and what is its significance for the modernity? These are for us two sides of the same question by Hölderlin. As a first step of this work, we shall examine the specificity of Hölderlin's criticism of reason in relationship with the German Idealism, especially its difference from Schelling and Fichte, from text "Urtheil und Seyn"; secondly we will consider the question of poetry, with the example of the specificity of Hölderlin's poetry, and the concept of intellectual intuition of which he spoke vaguely; and then we will discuss the relationship between time and the poetical language, or of art more generally, using help of Hölderlin's concept of "memory", and finally ask the question of the possibility of a poetical dwelling of man in the middle of the era of technology. <engl.> Die Dissertation behandelt die Beziehung zwischen der hölderlinschen Kritik der Vernunft und der Möglichkeit eines dichterischen Wohnens, um dem dichterischen Wohnen Bestimmungen zu geben. Dies führt zur Frage nach der Rolle der dichterischen Sprache und ihrer Bedeutung für die Moderne, die nichts anderes ist als die andere Seite des gleichen Problems bei Hölderlin. Zuerst sehen wir die Besonderheit der hölderlinschen Kritik der Vernunft im Rahmen des frühen deutschen Idealismus, besonders seinen Unterschied zu Schelling und Fichte ab “Urteil und Seyn”; dann zeigen wir, Hölderlins Theorie zum Trauerspiel spielt eine wichtige Rolle in seiner Kritik der Rationalität - die Philosophie kann als ein tragischer Versuch der Vernunft betrachtet werden. Danach sehen wir die Frage der Poesie, der hölderlinschen Poesie und seine Poetik, und schließlich besprechen wir die Beziehung zwischen Zeit und poetischer Sprache, oder Kunst im Allgemeinen, mit dem hölderlinschen Begriff der Erinnerung und stellen die Frage nach der Möglichkeit eines dichterischen Wohnens in der Mitte des Zeitalters der Technik. <dt.> |

Yet, scientific and technical occupations show a declining attractiveness (Renn et al., 2009). This also results from conceptions on attached activities in this specific occupational field. According to studies students often possess unclear and stereotyped images in the area of scientific occupations (Elster, 2009; Taskinen et al., 2008). Nevertheless, up to now there are no studies which give an insight into students’ concepts on certain scientific and technical occupations and more precisely the attached activities to them. The aim of this work is the analysis of students’ conceptions. These will serve as a basis for the development of an in-class training concept to support students in their occupational choices. The development also includes to find ways for integrating this matter in chemical classroom and teacher education. <engl.> Berufe in Naturwissenschaften und Technik haben für die Wirtschaftskraft Deutschlands eine hohe Bedeutung. Dennoch weisen naturwissenschaftliche und technische Berufe eine rückläufige Attraktivität auf (Renn et al., 2009).

Studien zufolge verfügen Schüler im Bereich der naturwissenschaftlichen Berufe häufig über unklare und stereotyp geprägte Vorstellungen (Elster, 2009; Taskinen et al. 2008). Bislang liegen jedoch noch keine Studien vor, die Aufschlüsse darüber geben, welche genauen beruflichen Tätigkeiten die Schüler in den verschiedenen naturwissenschaftlichen und technischen Berufen erwarten.

3A663618169.jsonld | Purposive three-dimensional reconstruction by means of a controlled environment | Retrieving 3D data using imaging devices is a relevant task for many applications in medical imaging, surveillance, industrial quality control, and others. As soon as we gain procedural control over parameters of the imaging device, we encounter the necessity of well-defined reconstruction goals and we need methods to achieve them. Hence, we enter next-best-view planning. In this work, we present a formalization of the abstract view planning problem and deal with different planning aspects, whereat we focus on using an intensity camera without active illumination. As one aspect of view planning, employing a controlled environment also provides the planning and reconstruction methods with additional information. We incorporate the additional knowledge of camera parameters into the Kanade-Lucas-Tomasi method used for feature tracking. The resulting Guided KLT tracking method benefits from a constrained optimization space and yields improved accuracy while regarding the uncertainty of the additional input. Serving other planning tasks dealing with known objects, we propose a method for coarse registration of 3D surface triangulations. By the means of exact surface moments of surface triangulations we establish invariant surface descriptors based on moment invariants. These descriptors allow to tackle tasks of surface registration, classification, retrieval, and clustering, which are also relevant to view planning. In the main part of this work, we present a modular, online approach to view planning for 3D reconstruction. Based on the outcome of the Guided KLT tracking, we design a planning module for accuracy optimization with respect to an extended E-criterion. Further planning modules endow non-discrete surface estimation and visibility analysis. The modular nature of the proposed planning system allows to address a wide range of specific instances of view planning. The theoretical findings in this work are underlined by experiments evaluating the relevant terms. |

3A880269340.jsonld | Generation and post modification of nanoparticles by plasmas | Generation, deposition and functionalization of nanoparticles (NPs) have received much numerous attention during the last decades due to the outstanding features of NPs and their unique roles in adjusting different properties of advanced materials. This dissertation includes three individual projects focused on synthesis and modification of different NPs based on using plasmas. Finding correlations between the plasma parameters and the observed phenomena is very crucial in this study. Particularly, we investigate metal and oxide-metal NP formation by a gas aggregation source (GAS) combined with conventional DC and/or pulsed DC magnetron sputtering. The next part of this dissertation is focused on the plasma characterization of a hollow electrode discharge and the influence of the ignited discharge, in radio frequency (RF) regime, on metal NPs. It is demonstrated that the ignited discharge can significantly change the characteristics of the passing NP beam by charging metal NPs and redistributing them in the beam. The last part of this research is devoted to study the synthesis of germanium (Ge) NPs in a nonthermal plasma reactor. It is shown that by adjusting the gas composition, and consequently varying the dominant mechanisms in the plasma, the size, crystallinity and surface chemistry of the synthesized Ge NPs can be controlled. |
3A1838096329.jsonld | Pareto and Reliability-Oriented Aeroelastic Shape Optimization of Bridge Decks | Due to the development of new technologies and materials, optimized bridge design has recently gained more attention. The aim is to reduce the bridge components materials and the CO2 emission from the cement manufacturing process. Thus, most long-span bridges are designed to be with high flexibility, low structural damping, and longer and slender spans. Such designs lead, however, to aeroelastic challenges. Moreover, the consideration of both the structural and aeroelastic behavior in bridges leads to contradictory solutions as the structural constraints lead to deck prototypes with high depth which provide high inertia to material volume ratios. On the other hand, considering solely the aerodynamic requirements, slender airfoil-shaped bridge box girders are recommended since they prevent vortex shedding and exhibit minimum drag. Within this framework comes this study which provides approaches to find optimal bridge deck cross-sections while considering the aerodynamic effects. Shape optimization of deck cross-section is usually formulated to minimize the amount of material by finding adequate parameters such as the depth, the height, and the thickness and while ensuring the overall stability of the structure by the application of some constraints. Codes and studies have been implemented to analyze the wind phenomena and the structural responses towards bridge deck cross-sections where simplifications have been adopted due to the complexity and the uniqueness of such components besides the difficulty of obtaining a final model of the aerodynamic behavior. In this thesis, two main perspectives have been studied; the first is fully deterministic and presents a novel framework on generating optimal aerodynamic shapes for streamlined and trapezoidal cross-sections based on the meta-modeling approach. Single and multi-objective optimizations were both carried out and a Pareto Front is generated. The performance of the optimal designs is checked afterwards. In the second part, a new strategy based on Reliability-Based Design Optimization (RBDO) to mitigate the vortex-induced vibration (VIV) on the Trans-Tokyo Bay bridge is proposed. Small changes in the leading and trailing edges are presented and uncertainties are considered in the structural system. Probabilistic constraints based on polynomial regression are evaluated and the problem is solved while applying the Reliability Index Approach (RIA) and the Performance Measure Approach (PMA). The results obtained in the first part showed that the aspect ratio has a significant effect on the aerodynamic behavior where deeper cross-sections have lower resistance against flutter and should be avoided. In the second part, the adopted RBDO approach succeeded to mitigate the VIV, and it is proven that designs with narrow or prolonged bottom-base length and featuring an abrupt surface change in the leading and trailing edges can lead to high vertical vibration amplitude. It is expected that this research will help engineers with the selections of the adequate deck cross-section layout, and encourage researchers to apply concepts of optimization regarding this field and develop the presented approaches for further studies. |
3A1678656763.jsonld | Pluvial flood loss to private households | Today, more than half of the world’s population lives in urban areas. With a high density of population and assets, urban areas are not only the economic, cultural and social hubs of every society, they are also highly susceptible to natural disasters. As a consequence of rising sea levels and an expected increase in extreme weather events caused by a changing climate in combination with growing cities, flooding is an increasing threat to many urban agglomerations around the globe.To mitigate the destructive consequences of flooding, appropriate risk management and adaptation strategies are required. So far, flood risk management in urban areas is almost exclusively focused on managing river and coastal flooding. Often overlooked is the risk from small-scale rainfall-triggered flooding, where the rainfall intensity of rainstorms exceeds the capacity of urban drainage systems, leading to immediate flooding. Referred to as pluvial flooding, this flood type exclusive to urban areas has caused severe losses in cities around the world. [...] |
3A1666096660.jsonld | Finite element discretization and iterative solution of total variation regularized minimization problems and application to the simulation of rate-independent damage evolutions | Abstract: The total variation regularization of optimization problems plays an important role in various applications like image processing and continuum mechanics. In contrast to Sobolev functions, functions with bounded total variation may jump across lower-dimensional subsets. This feature is particularly interesting in applications where solutions that develop sharp transitions between different ``phases'' are desired. For example, image processing models should be designed in such a way that sharp edges in the image are preserved. In continuum mechanics it is in some cases desirable to suggest models which provide solutions that are allowed to exhibit spatial jumps, e.g., in the modelling of the evolution of damage in concrete. However, while the usage of total variation regularization is appealing from the viewpoint of mathematical modelling, the development of efficient and reliable numerical methods for minimization problems including a total variation term is challenging due to the non-differentiability of the total variation.<br><br>An overview of existing numerical methods for a finite element discretization of a popular (bilaterally constrained) total variation minimization problem from image processing - namely the Rudin-Osher-Fatemi (ROF) problem - is given. The stability and convergence of three classes of algorithms is addressed and numerical comparisons are presented to identify the most efficient iterative scheme for our purposes.<br><br>Out of all approaches for total variation minimization, the alternating direction method of multipliers (ADMM), which is a flexible method to solve a large class of convex minimization problems, is analyzed in more detail. Advantages of the ADMM are its unconditional convergence with respect to the involved step size and its direct apllicability. However, the speed of convergence critically depends on the step size. In this thesis, variable step sizes are considered for the ADMM and an adjustment rule for the step size, which relies on the monotonicity of the residual, is proposed to accelerate the algorithm. Numerical experiments reveal significant improvements over established variants of the ADMM.<br><br>When dealing with functions with bounded variation, which may exhibit spatial jumps, the appropriate resolution of the jump sets is important to improve approximation properties of finite element functions and to reduce computational costs.

3A1826881646.jsonld | Holistic improvement of image acquisition and reconstruction in fluorescence microscopy | Recent developments in microscopic imaging led to a better understanding of intra- and intercellular metabolic processes and, for example, to visualize structural properties of viral pathogens. In this thesis, the imaging process of widefield and confocal scanning microscopy techniques is treated holistically to highlight general strategies and maximise their information content. Poisson or shot noise is assumed to be the fundamental noise process for the given measurements. A stable focus position is a basic condition for e.g. long-term measurements in order to provide reliable information about potential changes inside the Field-of-view. While newer microscopy systems can be equipped with hardware autofocus, this is not yet the widespread standard. For image-based focus analysis, different metrics for ideal, noisy and aberrated, in case of spherical aberration and astigmatism, measurements are presented. A stable focus position is also relevant in the example of 2-photon confocal imaging and at the same time the situation is aggravated in the given example, the measurement of the retina in the living mouse. In addition to the natural drift of the focal position, which can be evaluated by means of previously introduced metrics, rhythmic heartbeat, respiration, unrhythmic muscle twitching and movement of the mouse kept in artificial sleep are added. A dejittering algorithm is presented for the measurement data obtained under these circumstances. Using the additional information about the sample distribution in ISM, a method for reconstructing 3D from 2D image data is presented in the form of thick slice unmixing. This method can further be used for suppression of light generated outside the focal layer of 3D data stacks and is compared to selective layer multi-view deconvolution. To reduce phototoxicity and save valuable measurement time for a 3D stack, the method of zLEAP is presented, by which omitted Z-planes are subsequently calculated and inserted. |
3A894187775.jsonld | Development of multi-modal neural acquisition modality including optical coherence tomography and neuroelectrophysiology : towards a quantitative multi-modal rat brain atlas | Abstract: A well-established navigation method is one of the essential conditions to achieve a successful minimally-invasive brain intervention: it should be accurate, safe and online operable. For instance, in electrical deep brain stimulation (DBS), which involves delivering therapeutic electrical pulses via chronically implanted electrodes to the target brain regions through minimally-invasive surgical procedures, pre-operative MRT images are commonly used to guide the electrode implantation procedure in the surgery. To further facilitate a neuronal scale localization, microelectrode mapping that characterizes electrophysiological properties of the respective neuron types is often adopted as a complementary localization modality. Unfortunately, pre-operative image guidances may lose accuracy due to registration error or brain shifting during the surgery. Recent research has shown that optical coherence tomography (OCT) is a potential solution for this application by providing a high resolution and small probe dimension. When integrating the fiber-based OCT imaging with multi-site neurophysiological recordings, it is believed this multi-mode navigation modality will allow neurosurgeon to perform the minimally-invasive neurointervention with improved accuracy and efficacy.<br><br>In this study, a fiber-based spectral-domain OCT system utilizing a superluminescent diode (SLD) with the center wavelength of 840 nm providing 14.5 µm axial resolution was used as the imaging modality. A composite 125 µm diameter detecting probe with a gradient index (GRIN) fiber fused to a single mode fiber was employed. Signals acquired from forwarding-scanning were reconstructed into grayscale images by horizontally aligning A-scans from the same trajectory at different depths. The reconstructed images were able to display brain morphology along the fiber insertion trajectory. For scans of typical white matter, the signals showed a higher intensity of backscattered light with lower penetration depth, as well as a steeper attenuation slope compared to the scans typical for gray matter. The tissue's optical attenuation properties were then extracted from OCT A-scans. 16-channel polyimide-based thin-film microelectrode, of which the entire shank is 365 µm wide and 15 mm long, was used to facilitate neuroelectrophysiological recordings. The electrode was integrated with the OCT single mode fiber to construct a multi-mode microprobe assembly. Electrophysiological signals were o ... |
3A859511030.jsonld | Modeling and inversion of airborne full tensor magnetic gradiometry data in the Thuringian basin and forest | The recent development of airborne full tensor magnetic gradiometer (FTMG) systems, based on superconducting quantum interference devices (SQUID), allows to obtain the full magnetic gradient tensor of the Earth's magnetic field of large areas (10x10 km). This system allows acquiring all components of the magnetic gradient tensor. This tensor exhibits some advantages over conventional airborne magnetic field data, e.g. a higher spatial resolution and additional directional sensitivity. In this work a FTMG system was applied in the framework of the multidisciplinary INFLUINS project (Integrated fluid dynamics in sedimentary basins) in order investigate different areas in the Thuringian Basin and the neighboring highlands. Main goal was to map magnetic lineaments along major fault zones and to demonstrate the advantages of airborne FTMG. Full tensor data sets have been acquired with very low system noise of only 60 (pT/m). Two different case studies are presented: In the first case study a strong magnetic anomaly in the center of the Thuringian Forest, caused by the magmatic intrusion of the Höhenberger dolerite is analyzed, which exhibits indications of a significant remanent magnetization. Multiple magnetization vector inversions were performed using either the full magnetic gradient tensor or only the total field anomaly data. The inversion results are evaluated using magnetization directions acquired by paleomagnetic sampling and available geological information. In the second case study, a small magnetic anomaly was investigated. It was discovered while mapping magnetic anomalies along the Eichenberg-Gotha-Saalfeld fault zone, which is one of the major fault zones in the Thuringian Basin. The detected lineament is interpreted using the components of the magnetic gradient tensor, additional ground based geo-electrical data and available geological information. The inversion of the magnetic gradients revealed a steeply dipping zone of mostly induced magnetization. |

3A176802037X.jsonld | Soziale Teilhabe von älteren Menschen : empirischer Vergleich und sozialethische Reflexion dreier Wohlfahrtsstaaten | In this book, the social participation of older people in Germany, Sweden and Switzerland (multinational) is analysed in terms of income/property, health, housing and social networks (multidimensional). Drawing on the theory of French social solidarity, the author pinpoints the minimum provisions for a social contract which the members of society conclude with each other on the basis of experiences of inequality. In doing so, they recognise themselves as free and equal and secure themselves the right to comparable and largely similar living conditions. The gap between normative standards and social policy practice can be used to describe reform proposals for an inclusive policy for the elderly. Empirisch analysiert wird die soziale Teilhabe von älteren Menschen in Deutschland, Schweden und der Schweiz (multinational) hinsichtlich Einkommen/Vermögen, Gesundheit, Wohnen und sozialer Netzwerke (multidimensional). Aus der Gesellschaftstheorie des Französischen Solidarismus werden Mindestbestimmungen eines Gesellschaftsvertrags abgeleitet, den die Gesellschaftsmitglieder aufgrund von Ungleichheitserfahrungen miteinander schließen. Sie anerkennen sich als Freie und Gleiche und sichern sich das Recht auf vergleichbare, nicht extrem unterschiedliche Lebensbedingungen zu. Aus der Lücke zwischen dem normativen Anspruch und der sozialpolitischen Praxis lassen sich Reformvorschläge für eine inklusive Altenpolitik beschreiben. |

3A662149351.jsonld | Human capital and social capital in the entrepreneurial process | This dissertation is a compilation of papers on entrepreneurship which investigate related research questions. The unifying element of the different parts is the focus on two important concepts in entrepreneurship research, namely human capital and social capital. Briefly, the four main chapters deal with the origins of human and social capital, its use in different stages of the entrepreneurial process and its impact on entrepreneurial success. Regarding the two main concepts of this thesis, human capital is the central topic in Chapters 3 and 4. Thereby, Chapter 3 studies the origins of a specific aspect of human capital, namely the balance of skills and their performance effects in the nascent phase. The paper presented in Chapter 4 focuses on human capital in entrepreneurial teams. Specifically, the venture performance advantages and disadvantages of functional heterogeneity in the post-nascent phase are investigated. Chapters 2 and 5 are mainly dedicated to social capital. In Chapter 2 the role of regional characteristics in the formation of individual social capital as well as the subsequent impact of social capital on the decision to engage in concrete venture creation is studied. Chapter 5 sheds light on the use of social capital in the nascent phase and its performance implications in the post-nascent phase. |
3A1702127826.jsonld | Gender and the genocide in Rwanda : women as rescuers and perpetrators | This book examines the mobilization, role, and trajectory of women rescuers and perpetrators during the 1994 genocide in Rwanda. While much has been written about the victimization of women during the 1994 genocide in Rwanda, very little has been said about women who rescued targeted victims or perpetrated crimes against humanity. This book explores and analyzes the role played by women who exercised agency as rescuers and as perpetrators during the genocide in Rwanda. As women, they took actions and decisions within the context of a deeply entrenched patriarchal system that limited their choices. This work examines two diverging paths of women's agency during this period: to rescue from genocide or to perpetrate genocide. It seeks to answer three questions: First, how were certain Rwandan women mobilized to participate in genocide, and by whom? Second, what were the specific actions of women during this period of violence and upheaval? Finally, what were the trajectories of women rescuers and perpetrators after the genocide? Comparing and contrasting how women rescuers and perpetrators were mobilized, the actions they undertook, and their post-genocide trajectories, and concluding with a broader discussion of the long-term impact of ignoring these women, this book develops a more nuanced and holistic view of women's agency and the genocide in Rwanda. This book will be of much interest to students of gender studies, genocide studies, African politics and critical security studies |

3A1735970697.jsonld | Interdisziplinarität der Rechtsdogmatik | How does jurisprudence relate to other disciplines? Alexander Stark's deliberative concept examines the eligibility of knowledge and insights from neighbouring fields for legal argumentation – and reveals where the lines of interdisciplinary legal dogmatics are to be drawn. Das Verhältnis der Rechtsdogmatik zu den Wissensbeständen anderer Disziplinen steht seit langem auf dem rechtswissenschaftlichen Diskurstableau. Nach wie vor ist ungeklärt, ob und ggf. inwieweit naturwissenschaftliche, ökonomische, ethische und sonstige Erkenntnisse und Einsichten in die rechtsdogmatische Argumentation einbezogen werden können, dürfen und sollen. Alexander Stark untersucht diese Fragen auf der Grundlage eines deliberativen Ansatzes der Rechtsdogmatik, dem zufolge die dogmatischen Akteure auf einer Beobachtungsebene die Handlungen von Rechtsakteuren reflektieren, imaginieren und kritisieren. Im Zentrum dieser Deliberationsprozesse stehen – unter der Ägide der Rationalität – rechtliche wie nicht-rechtliche normative Gründe. Interdisziplinäre Andockstellen zeigen sich ausgehend von diesem Ansatz überall dort, wo nachbardisziplinäre Wissensbestände als normative Gründe für die Rechtsdogmatik zum Zuge kommen. |
3A1658693183.jsonld | Formwandel der Verfassung : Die postdemokratische Verfasstheit des Transnationalen | Whether in global markets, in the EU, or in international law - constitutions are long being formed beyond the state with severe consequences. In this post-democratic constitutionalism, a market-liberal program is given the status of an unquestionable consensus, reinforced by a higher-ranking law. Kolja Möller connects system theory, post-Marxist resources, and democracy theory to show, using different examples: Neither returning to national democracy nor spreading individual global citizen rights will improve this situation. Instead, a deposing power is needed to resolve the substantive over-formation of constitutions beyond the state. The new and critical constitutional theory thus created challenges the current diagnoses of declining status of democracy, and sheds a new light on the »democratic deficit« of globalization. |

3A715639269.jsonld | Crystallographic and mutational studies of bacterial cytochrome c peroxidases | Zusammenfassung: Cytochrome c peroxidases (Ccps) are reactive oxygen species (ROS) detoxifying enzymes that can be found in various Gram negative bacteria. They consist of two domains with one heme group each and catalyze the reduction of hydrogen peroxide two water. The delta proteobacterium Geobacter sulfurreducens possesses two copies of Ccp encoding genes (ccpA and macA). All known structures of cytochrome c peroxidases show an inactive and closed conformation in the oxidized state. The only exception is the enzyme of Nitrosomonas europaea exhibiting a constant open conformation, even in the oxidized state. Based on sequence alignments protein variants of CcpA and MacA were created and the structures were solved. The CcpA variants S134P and S134P/V135K showed a partially open enzyme regarding the active-side environment. Escherichia coli possesses an gene encoding for a predicted Ccp that has a third domain with an additional heme group (yhjA). The structure of the reduced YhjA was solved to a resolution of 2.8 A and shows the N-terminal extension with a His/Met coordinated heme group and an open active site Zusammenfassung: Cytochrom c Peroxidasen (Ccps) entgiften reaktive Sauerstoffspezies (ROS) und sind weit verbreitet unter Gram-negativen Bakterien.

3A1010615254.jsonld | The Navier-Stokes equations for elliptic quasicomplexes | The classical Navier-Stokes equations of hydrodynamics are usually written in terms of vector analysis. More promising is the formulation of these equations in the language of differential forms of degree one. In this way the study of Navier-Stokes equations includes the analysis of the de Rham complex. In particular, the Hodge theory for the de Rham complex enables one to eliminate the pressure from the equations. The Navier-Stokes equations constitute a parabolic system with a nonlinear term which makes sense only for one-forms. A simpler model of dynamics of incompressible viscous fluid is given by Burgers' equation. This work is aimed at the study of invariant structure of the Navier-Stokes equations which is closely related to the algebraic structure of the de Rham complex at step 1. To this end we introduce Navier-Stokes equations related to any elliptic quasicomplex of first order differential operators. These equations are quite similar to the classical Navier-Stokes equations including generalised velocity and pressure… |

3A1698985088.jsonld | Die Rechtsstellung religiöser Minderheiten im Iran : Minderheitenschutz im Spannungsfeld zwischen Völkerrecht, islamischem Recht und dem Recht der Islamischen Republik Iran | This study shows that the personal statutes (šakhsīye-e ahvāl) of the officially recognised religious minorities (Zoroastrians, Jews and Christians), which are constitutionally guaranteed in Iran, grant them rights with regard to their personal affairs. Nevertheless, measures have been taken which, above all, affect the rights of religious minorities under international law according to Art. 27 of the IPCPR. This work is the first to deal with a legal comparison of these statutes. In addition, the author discusses the protection of religious minorities in international law, the legal status of religious minorities in Islamic law and, in detail, the legal status of religious minorities in Iran (including Sunnis, Sufi orders, Ahl-e Haq orders, Alevis, Zaidites, Ismailites, Zoroastrians, Jews, Christians, Baha'i, Mandaeans and Yezidis). The author offers solutions to the problems of religious minorities and contributes to the future harmonisation of Iranian law and international law. Diese Arbeit zeigt, dass die im Iran verfassungsrechtlich garantierten Personalstatuten ("ahvāl-e šakhsīye") der offiziell anerkannten religiösen Minderheiten (Zoroastrier, Juden und Christen), diesen durchaus Rechte hinsichtlich ihrer persönlichen Angelegenheiten gewähren. Dennoch kommt es zu Maßnahmen, die vor allem die völkerrechtlichen Rechte der religiösen Minderheiten nach Art. 27 IPbpR beeinträchtigen. Die Arbeit behandelt erstmalig einen Rechtsvergleich dieser Statuten. Zudem behandelt die Autorin den Schutz religiöser Minderheiten im Völkerrecht, die Rechtsstellung religiöser Minderheiten im islamischen Recht und ausführlich die Rechtstellung religiöser Minderheiten im Iran (u.a. Sunniten, Sufi-Orden, Ahl-e Haq-Orden, Aleviten, Zaiditen, Ismailiten, Zoroastrier, Juden, Christen, Bahai, Mandäer und Yeziden).

3A847255913.jsonld | From Spitzer mid-infrared observations and measurements of peculiar velocities to constrained simulations of the local universe | Galaxies are observational probes to study the Large Scale Structure. Their gravitational motions are tracers of the total matter density and therefore of the Large Scale Structure. Besides, studies of structure formation and galaxy evolution rely on numerical cosmological simulations. Still, only one universe observable from a given position, in time and space, is available for comparisons with simulations. The related cosmic variance affects our ability to interpret the results. Simulations constrained by observational data are a perfect remedy to this problem. Achieving such simulations requires the projects Cosmic flows and CLUES. Cosmic flows builds catalogs of accurate distance measurements to map deviations from the expansion. These measures are mainly obtained with the galaxy luminosity-rotation rate correlation. We present the calibration of that relation in the mid-infrared with observational data from Spitzer Space Telescope. Resulting accurate distance estimates will be included in the third catalog of the project. In the meantime, two catalogs up to 30 and 150 Mpc/h have been released. We report improvements and applications of the CLUES' method on these two catalogs. The technique is based on the constrained realization algorithm. The cosmic displacement field is computed with the Zel'dovich approximation. This latter is then reversed to relocate reconstructed three-dimensional constraints to their precursors' positions in the initial field. The size of the second catalog (8000 galaxies within 150 Mpc/h) highlighted the importance of minimizing the observational biases. By carrying out tests on mock catalogs, built from cosmological simulations, a method to minimize observational bias can be derived. Finally, for the first time, cosmological simulations are constrained solely by peculiar velocities. The process is successful as resulting simulations resemble the Local Universe. The major attractors and voids are simulated at positions approaching observational positions by a few megaparsecs, thus reaching the limit imposed by the linear theory. |

Relying on interviews with office holders, further members of the executive boards and backbenchers, it firstly highlights their challenging and complex role within parliamentary democracy. Secondly, it discloses the multifaceted steering capacities party group leaders have at their disposal, and how they can be used during decision-making processes. Overall, the investigation demonstrates the office holders’ pivotal role in democratic and well-functioning party groups. In addition, it shows how important they are for the parliament as a whole, since the party group leaders substantially contribute to the functioning of the institution that functionally and symbolically resides at the heart of representative democracy. Die Studie untersucht zum ersten Mal systematisch die Führungsposition der Fraktionsvorsitzenden im Deutschen Bundestag. Basierend auf zahlreichen Interviews mit Fraktionsführern, Mitgliedern der Leitungsebene und der Fraktionsbasis beleuchtet sie zum einen die komplexe und anspruchsvolle Rolle der Vorsitzenden im Parlamentsbetrieb. Zum anderen wird aufgezeigt, über welche vielfältigen Steuerungsmöglichkeiten die Amtsinhaber verfügen und wie sie diese bei der – formal demokratisch angelegten – Willensbildung der Fraktion einsetzen können. Damit wird ein wesentlicher Teil des parlamentarischen Führungsprozesses empirisch fundiert freigelegt. Da die Fraktionen die wichtigsten Handlungseinheiten im Deutschen Bundestag darstellen, wird nicht zuletzt deutlich, wie ihre Vorsitzenden zur institutionellen Funktionserfüllung des Parlaments und damit zur Herstellung und Legitimierung allgemein-verbindlicher Entscheidungen beitragen (müssen). |

In German tax law the legislator often interferes with this process by retroactively changing the law. This raises questions about the separation of powers, protection of legitimate interests, effective legal protection, and legal continuity. Höchstrichterliche Entscheidungen prägen die Auslegung gesetzlicher Regelungen. Eine Rechtsfrage wird in der Praxis regelmäßig so entschieden, wie das zuständige Bundesgericht parallele Fälle beurteilt hat. Im Steuerrecht verhindert der Gesetzgeber diese Orientierungswirkung häufig, indem er auf Entscheidungen des Bundesfinanzhofs mit einer Anpassung des Gesetzestextes sowohl für zukünftige als auch für vergangene Fälle reagiert. Tim Maciejewski untersucht, wann derartige Nichtanwendungsgesetze in Konflikt mit dem Grundsatz der Gewaltenteilung geraten oder subjektive Rechte der betroffenen Bürger auf Vertrauensschutz und effektiven Rechtsschutz beeinträchtigen. Umgekehrt arbeitet er heraus, dass Nichtanwendungsgesetze einen Beitrag zur Rechtskontinuität leisten können und entwickelt ein Abwägungsmodell zu ihrer verfassungsrechtlichen Rechtfertigung.

3A810707020.jsonld | Culture, Northern Ireland, and the Second World War | This book explores the impact of the Second World War on literature and culture in Northern Ireland between 1939 and 1970. It argues that the war, as a unique interregnum in the history of Northern Ireland, challenged the entrenched political and social makeup of the province and had a profound effect on its cultural life. Critical approaches to Northern Irish literature and culture have often been circumscribed by topographies of partition and sectarianism, but the Second World War generated conditions for reimagining the province within broader European and global contexts. These have perhaps been obscured by the amount of critical attention that has been paid to the impact of the Troubles on the culture of the province, and for this reason the book focuses on material produced before the flaring of political violence towards the end of the 1960s. Drawing on archival research, over four chapters the book describes the activities of an eccentric collection of artists and writers during and after the Second World War, and considers how the awkward position of the province in relation to the war is reflected in their work. 0 |

The former create a more or less continuous layer while the latter should be sparse enough to leave an open canopy. What has long intrigued ecologists is how these two competing plant life forms of vegetation coexist. Initially attributed to resource competition, coexistence was considered the stable outcome of a root niche differentiation between trees and grasses. The importance of environmental factors became evident later, when data from moister environments demonstrated that tree cover was often lower than what the rainfall conditions would allow for. Our current understanding relies on the interaction of competition and disturbances in space and time. Hence, the influence of grazing and fire and the corresponding feedbacks they generate have been keenly investigated.

3A73626681X.jsonld | Geschichtsverständnis in indonesischen Schulen - Deutsche Geschichte in drei senior high schools | Zusammenfassung: The MA thesis deals with perceptions on history and the past by senior high school students and teachers in Yogyakarta, Indonesia. On a theoretical level it tries to develop a new anthropological approach to history and the past. Based on the concepts of Historical Culture (Geschichtskultur) and Historical Consciousness (Geschichtsverständnis), originating in the German didactics of history, I target to find a more comprehensive way of approaching the past as “history” is still mainly related to the academic environment. It therefore seems more appropriated to speak of “Historical Understanding” (Geschichtsverständnis) and “Historical Communication” (Historische Kommunikation). Especially the latter also offers methodological opportunities as it is intended to include all kinds of references to the past – be it verbal, corporal, emotional or imagined. The empirical part represents a concrete implementation of these theoretical and methodological thoughts and deals with the Historical Understanding of students and teachers of the concrete Indonesian setting as well as of the German Third Reich. It reveals that in the context of senior high schools, misconceptions of the NS-Regime and the usage of Nazi symbols are due to a multiplicity of reasons and can hardly be explained by a (neo-)Nazi orientation Zusammenfassung: Die vorliegende Magisterarbeit beschäftigt sich mit dem Geschichts- und Vergangenheitsverständnis von SchülerInnen und LehrerInnen verschiedener senior high schools in Yogyakarta, Indonesien. Im theoretischen Teil wird versucht, eine neue ethnologische Herangehensweise an Geschichte und die Vergangenheit zu entwickeln, da dies bisher stark vernachlässigt wurde. Basierend auf den Konzepten „Geschichtskultur“ und „Geschichtsverständnis“, die in der deutschen Geschichtsdidaktik entwickelt wurden, wird ein holistischer Zugang zu Vergangenheit angestrebt. Dies scheint notwendig, da „Geschichte“ in vielen Zusammenhängen meist immer noch stark mit dem akademischen Kontext verbunden ist. Alternativ werden daher die Begriffe „Geschichtsverständnis“ und „Historische Kommunikation“ vorgeschlagen. Da sie sich auf sehr unterschiedliche Vergangenheitsbezüge, seien sie verbal, körperlich, emotional oder imaginiert, beziehen lassen, liefern sie gute methodologische Anknüpfungspunkte und werden einer induktiv sowie empirisch orientierten Herangehensweise besser gerecht. Im empirischen Teil werden diese theoretischen und methodischen Vorüberlegungen dann auf den konkreten Untersuchungsraum angewendet. Hierbei steht das Geschichtsverständnis der SchülerInnen und LehrerInnen sowohl in Bezug auf die eigene indonesische Geschichte als auch hinsichtlich des Dritten Reiches in Deutschland im Vordergrund. Es zeigt sich, dass der spezifische Umgang mit der eigenen Geschichte auch auf die (modische) Verwendung von NS-Symbolik übertragen wird und diese nicht einer (neo-)nazistischen Einstellung, sondern einer Vielzahl von sehr unterschiedlichen Gründen zuzuschreiben ist |
3A616754272.jsonld | Apparent horizons and marginally trapped surfaces in numerical general relativity | The main topic of this dissertation are marginally outer trapped surfaces (MOTS) in numerical general relativity. MOTSs are closed two-dimensional surfaces around black holes, at which the expansion of outgoing null rays vanishes. They are used to determine the approximate location of the event horizon at one instant of time or to give the mass and spin of the enclosed black hole. It was examined whether or how MOTSs can overlap when two black holes come close to each other. In contrast to previously published results from other groups no overlap was found, neither for the axisymmetric case nor for the inspiraling case of two black holes. This discrepancy was explained by the use of embedding diagrams. MOTSs are described by an elliptic partial differential equation. Newton methods can solve these kinds of problems. One change was examined that enlarges the convergent regime for these methods. For that the function under consideration was multiplied by an appropriate term. Alongside it was considered how eigenvalues can serve as an indicator for the convergence of the Newton method. These eigenvalues are taken from the iteration matrix that appears when solving one step of the Newton iteration. It is not possible to show the predictive power with mathematical rigour. Nevertheless in praxis the method shows good results. |

3A879223790.jsonld | Die Behandlung von tacit collusion im europäischen und deutschen Kartellrecht | Firms in an oligopoly are able to implicitly coordinate their conduct and reach the market results of a cartel without entering into an explicit cartel agreement. There is a divergence of views as to whether tacit collusion can even be identified without ambiguity and differentiated from competitive behaviour. This work analyses economic approaches to identify tacit collusion and in the following examines to what extend tacit collusion is covered by the provisions of competition law. It outlines the consideration of coordinated effects in the area of merger control as well as the controversy regarding “concerted practices” within the cartel prohibition. However, the main emphasis is a potential abuse of collective dominance based on tacit collusion. In oligopolistischen Märkten ist es Unternehmen möglich, ihr Verhalten stillschweigend aufeinander abzustimmen und ohne klassische Kartellabsprache die Marktergebnisse eines Kartells zu erreichen. Schon die Frage, ob tacit collusion auf einem Markt überhaupt eindeutig zu identifizieren und trennscharf von wettbewerblichem Verhalten abgegrenzt werden kann, ist noch nicht befriedigend beantwortet.Die Arbeit untersucht die wirtschaftswissenschaftlichen Ansätze zur Identifizierung von tacit collusion und wendet sich daraufhin der Frage zu, inwieweit tacit collusion unter die geltenden Normen des Kartellrechts subsumiert werden kann. Dabei wird auf die Berücksichtigung koordinierter Effekte in der Fusionskontrolle ebenso eingegangen wie auf die Diskussion zum Begriff der „abgestimmten Verhaltensweise“ im Kartellverbot.Im Schwerpunkt aber beschäftigt sich die Arbeit mit der Frage, inwieweit tacit collusion den Missbrauch einer gemeinsamen marktbeherrschenden Stellung begründen kann. |
3A1827603305.jsonld | Modeling emotion across languages, label formats, and linguistic levels | Language-based emotion analysis finds itself in a paradoxical situation. In the past decades, a plethora of datasets have been created, covering diverse aspects of natural language and affective states. However, the considerable volume of resulting gold data is scattered across many design decisions in dataset creation, acting as sources of heterogeneity (e.g., different natural languages, linguistic units of different sizes such as words, sentences, and texts, the choice for a particular set of emotion variables, and the selection of a particular viewpoint such as the reader or the writer perspective on emotion). On the one hand, this proliferating heterogeneity makes it difficult to re-use existing datasets and software tools or to compare experimental results following different design decisions. On the other hand, this heterogeneity is empirically adequate and valuable from an application perspective. Thus, the solution to the heterogeneity problem cannot be to simply reduce the number of possible design choices through community-wide consensus. Rather, what is needed is a delicate balance between fostering the diversity of emotion data and developing new methods to tackle the resulting comparability issues. This interplay between diversity and comparability of emotion data is the focus area of this thesis and the seven studies compiled within it. The larger vision behind this dissertation is to arrive at a research landscape where diversity and comparability no longer act as antagonists and instead every new sample of annotated data, regardless of the specifics of its annotation design, benefits the endeavor of emotion analysis as a whole. While NLP is still far from achieving this goal, the presented research results, culminating in the establishment of an “emotion interlingua” in the final study, constitute a significant step in this direction. |
3A1693603101.jsonld | Die Professionalisierung tiergestützter Dienstleistungen : von der Weiterbildung zum eigenständigen Beruf | Using the example of pedagogical, medical and social services that are rendered with the help of animals, this dissertation will analyse procedural processes in the development of professional fields. The author will determine how clearly defined professional profiles are changed or professionalised by social or biographical factors. The professionalisation processes will be reconstructed using interviews with providers of animal-supported services. A secondary analysis from a user perspective will complete the picture. Finally, the author will draft the development of an interactionistic professional theory and suggest practical recommendations for action. Summarising the different fields of activity under the umbrella term "animal-supported services" can accelerate the development of a new professional profile that is integrated into the public vocational training system. Am Beispiel von pädagogischen, medizinischen und sozialen Dienstleistungen, die mithilfe von Tieren erbracht werden, analysiert die Dissertation prozessuale Abläufe in der Berufsfeldentwicklung. Die Autorin arbeitet heraus, wie fest definierte Berufsbilder durch gesellschaftliche oder biografische Impulse der Akteure verändert und professionalisiert werden. Die Professionalisierungsprozesse werden anhand von Interviews mit Anbietern tiergestützter Dienstleistungen rekonstruiert. Eine Sekundäranalyse aus der Nutzersicht ergänzt das Bild. Abschließend formuliert die Autorin den Entwurf einer interaktionistischen Professionstheorie und schlägt Handlungsempfehlungen für die Praxis vor: Eine Zusammenfassung der verschiedenen Tätigkeitsfelder unter dem Begriff "tiergestützte Dienstleistungen" kann die Entwicklung eines neuen Berufsbildes beschleunigen, das in das staatliche Berufsbildungssystem integriert wird. |
3A168180848X.jsonld | Parlamentarier als Beruf : Rekrutierungswege und politische Karrieren am Beispiel des Deutschen Bundestages | The fact that politics has become a profession is inferred in the theoretical part of this work and substantiated in the empirical part with extensive data. Within its institutional framework, political professionalisation has led to the social figure of the professional politician. From the author's point of view, it is remarkable that the trend towards this professionalisation has not led to significant changes in the recruitment patterns and career paths of members of parliament. On the contrary, Herzog’s career types still prove valid today and have only had to be moderately refined. This shows an astonishing continuity in the formation of political elites. Germany’s very stable institutional framework, which determines access to and the attractiveness of political careers, has obviously also led to the stabilisation of career types. Die politische Professionalisierung hat innerhalb der institutionellen Rahmenbedingungen zur Sozialfigur des Berufspolitikers geführt. Diese Entwicklung wird im theoretischen Teil der Arbeit hergeleitet und im empirischen Teil mit umfangreichen Daten belegt. Bemerkenswert ist, dass es dabei nicht zu erheblichen Veränderungen in den Rekrutierungsmustern und Karriereverläufen der Abgeordneten gekommen ist. Vielmehr erweisen sich die von Dietrich Herzog herausgearbeiteten Karrieretypen auch heute noch als gültig und mussten nur moderat angepasst werden. Es zeigt sich damit eine erstaunliche Kontinuität in der politischen Elitenbildung. Die in Deutschland sehr gefestigten institutionellen Rahmenbedingungen, die den Zugang und die Attraktivität politischer Karrieren determinieren, haben offensichtlich auch zu einer Stabilisierung der Karrieretypen geführt. |
3A1007194464.jsonld | Kassenärztliche Vereinigungen als öffentliche Auftraggeber im Sinne des GWB-Vergaberechts? : ein Beitrag zur Auslegung des Begriffs des öffentlichen Auftraggebers im Licht der Rechtsprechung des Europäischen Gerichtshofs | As early as in 2009, the European Court of Justice (ECJ) clarified that Germany’s statutory health insurance funds are contracting authorities as defined by European public procurement law (especially the Directive 2004/18/EU, which was meanwhile been repealed and replaced by the Directive 2014/24/EU).On the other hand, in a later ruling the ECJ did not qualify Germany’s medical associations as contracting authorities. So those institutions do not have to apply the rules of the European public procurement law but only the rules of their respective public budget laws.Referring to the aforementioned rulings by the ECJ, this work focuses on the “Kassenärztliche Vereinigungen” (Associations of Statutory Health Insurance Doctors) from the perspective of whether they too should be regarded as “contracting authorities”. An examination of their position in the German public health system reveals that the “Kassenärztliche Vereinigungen” have similarities to both the statutory health insurance funds and the medical associations. Schon 2009 hat der EuGH die gesetzlichen Krankenkassen in Deutschland als öffentliche Auftraggeber im EU-vergaberechtlichen Sinn eingestuft. Sie sind damit bei Auftrags- und Konzessionsvergaben über dem sog. Schwellenwert an das – europarechtliche Vorgaben umsetzende – GWB-Vergaberecht gebunden.Demgegenüber hat der EuGH im Jahr 2013 berufsständischen Einrichtungen wie Ärztekammern die Eigenschaft als öffentlicher Auftraggeber abgesprochen. Sie fallen demnach nicht in den Anwendungsbereich des GWB-Vergaberechts, sind bei ihren Beschaffungen also regelmäßig „nur“ den für sie geltenden haushaltsrechtlichen Vorgaben unterworfen.Im Licht der beiden angesprochenen EuGH-Urteile beschäftigt sich die Arbeit mit der Auftraggebereigenschaft Kassenärztlicher Vereinigungen, die angesichts ihrer gesundheitssystemischen Stellung Gemeinsamkeiten sowohl mit gesetzlichen Krankenkassen als auch mit Ärztekammern aufweisen. |

3A823815145.jsonld | Linguistic variation, identity construction and cognition | Speakers use a variety of different linguistic resources in the construction of their identities, and they are able to do so because their mental representations of linguistic and social information are linked. While the exact nature of these representations remains unclear, there is growing evidence that they encode a great deal more phonetic detail than traditionally assumed and that the phonetic detail is linked with word-based information. This book investigates the ways in which a lemma’s phonetic realisation depends on a combination of its grammatical function and the speaker’s social group. This question is investigated within the context of the word like as it is produced and perceived by students at an all girls’ high school in New Zealand. The results are used to inform an exemplar-based model of speech production and perception in which the quality and frequency of linguistic and non-linguistic variants contribute to a speaker’s style. |
3A1748692046.jsonld | Rechtsvergleichung im Völkerrecht | This book investigates comparative law's relevance to the development of international law, particularly the way it functions when it comes to designing and applying international treaties, determining customary law, and ascertaining general principles. Based on a broad assessment of decision-making practices of various international courts as well as on selected works of the International Law Commission, the author lays the groundwork for a methodology for comparative analyses in international law. This study is based on the assumption that methodologically guided comparative legal analyses can contribute to promoting international law's coherence and effectiveness, mainly by increasing the rationality, clarity, and legitimacy of international treaty-making and judicial decision-taking. Till Markus untersucht die Bedeutung der Rechtsvergleichung für das Völkerrecht, insbesondere im Hinblick auf die Gestaltung, Bestimmung und Anwendung seiner drei primären Rechtsquellen. Aufbauend auf einer Rekonstruktion der Entscheidungspraxis verschiedener internationaler Gerichte sowie im Hinblick auf ausgewählte Arbeiten der Völkerrechtskommission entwickelt er erste Grundrisse einer Methodik der Rechtsvergleichung im Völkerrecht. Die Untersuchung basiert auf der Annahme, dass methodisch angeleitete Rechtsvergleiche einen Beitrag zur Effektuierung und Ordnung des Völkerrechts dadurch leisten, dass sie das Maß an Rationalität, dogmatischer Klarheit und Legitimität völkerrechtlicher Vertragsgestaltung und gerichtlicher Entscheidungsfindung steigern. |

3A520357264.jsonld | Optimal control of semilinear elliptic equations with applications to sublimation crystal growth | This thesis is concerned with an optimal control problem, arising from the optimization of the temperature distribution within the sublimation growth of semiconductor single-crystals. The problem consists of a semilinear elliptic partial differential equation with nonlocal radiation interface conditions and pointwise control and state constraints. It is treated by two different approaches: First, a semilinear optimal control problem with monotone nonlinearity and pointwise state constraints is considered. It is known that the Lagrange multipliers associated to the pointwise state constraints are in general regular Borel measures. This lack of regularity leads to theoretical and numerical challenges. However, by using a Larentiev-type regularization, the problem can be transformed to a control-constrained optimization problem, that provides regular Lagrange multipliers. In the linear-quadratic case, it is possible to prove strong convergence of the solutions of the regularized problems to the solution of the original problem for regularization parameter tending to zero. This result is confirmed by numerical observations. The second part of this thesis deals with a purely control-constrained optimal control problem that accounts for the non-monotone nonlinearity caused by the nonlocal radiation interface conditions. Using Brezi's theorem for pseudomonotone operators, one proves the unique existence of solutions of the semilinear state equation. Moreover, based on Stampacchia's truncation method, the boundedness of the solutions is shown ... |
3A779744411.jsonld | On selection problems with several non-perfect experts | In work and private life we have to make decisions every day - knowingly or unknowingly. But in some cases the process of decision making can be very complicated and difficult. For that reason, consulting more than one decider has proved useful in practice. But, are decisions made by several deciders better than decisions made by a single decider in general? In this thesis we investigate six types of selection problems with two or more experts. In each of these selection problems the basic task of the experts is to select k out of n given items with maximal values or deleting n-k out of n items with minimmal values. These experts are not perfect, but the quality of their selected items is better than those of randomly selected items. Because of not allowing any exchange of information between the acting experts, they are totally independent and observe their own preference orders only. Considering two experts A and B with equal noise levels selecting k out of n items, we focus on the question, whether the items selected by A and B are better then the items selected by A only. It shows that each double-expert-scenario with at least one action of expert B is better than letting A select all k items. Moreover, we observed interesting structures within the rankings of all these double-expert-scenarios. Considering experts with different noise levels, we are interested in the best and worst selection orders. For alternately acting experts we achieve the best results if the worst expert selects the first item, the second worst expert the second item, ..., and the best expert the k-th item. To get the worst results, the experts should act in reverse order. |
3A896541886.jsonld | Irradiation processing of major dust components | In this thesis the behaviour of iron-containing and -free amorphous soot under UV- and X-ray irradiation in the range from 6 eV to 500 eV was investigated. The interstellar extinction bump at 217nm has been known for more than fifty years, but its carrier is still unknown. Current research supports the idea that this band can be attributed to UV-processed carbon. In order to produce soot samples, graphite was vaporised under both a hydrogen-free and – containing helium atmosphere by means of laser-ablation, whereupon it condensed to nanoparticles. Amorphous soot forms a band around 208nm to 200nm upon UV-irradiation. This band is most probably borne by curved graphene-layers that are visible under the electron miscroscope. The curved layers arise from a process consisting of graphitisation allowing the growth of the layers, and the formation of Stone-Wales defects. Photons with energies below 8eV mainly cause graphitisation, those above 8eV mainly cause the formation of Stone-Wales defects. The thus-formed structures resemble onion-like fullerene-fragments. Compared to planar graphene layers, their orbitals are deformed and behave more diamond-like. That ultimately causes a blue-shift of the pi-electrons compared to planar graphene. Since iron is known to be catalyst for the formation of graphene layers, iron powder was added to pressed graphite powder. Upon laser-ablation, the mixture produced graphene-covered iron nano-particles with even more than one layer. The incorporation of iron resulted in an increased mass absorption coefficient and did not impede the formation of the band. This gives a hint about the depletion of iron in the interstellar medium |
3A1837705828.jsonld | Memories of German colonialism in Tanzania | German colonial history in today Tanzania Mainlad is extensively documented, but it has not been studied from its memory perspective despite it being widely remembered among the Tanzanians. This book documents German colonial memories as shared cultural legacy that exists in forms of monuments, archives and historical sites. It also presents them as trans-generational memory narratives that live in people's memories that are also commemorated in different ways like erection of war monuments. The book analyzes memories of colonialism from the historical perspective, showing how the collective memories like monuments and commemorations have undergone structural and institutional changes over time. The study uses Michael Rothberg's multi-directional theory, together with other theoretical approaches to analyze various forms of German colonial memories in Tanzanian context. The findings, which are analyzed historically, indicate that the collective memories of the Germans are cultural, communicative, commemorative, functional and topographical. They are also traumatic as well as nostalgic |

3A365236004.jsonld | Experimente und numerische Modellierung zum Ladungsträgertransport in a-Si:H/c-Si Heterodioden | Heterodiodes of amorphous (a-Si:H) and crystalline silicon were examined that are used as solar cells. The laboratory structures were processed by deposition of doped a-Si:H on c-Si wafers using PECVD (Plasma Enhanced Chemical Vapour Deposition). Temperature dependent current-voltage curves were measured. The comparison of the results with different theoretical models indicates tunneling of electrons over a spike in the conduction band at the heterojunction and tunneling assisted recombination current in c-Si. Temperature and frequency dependent capacitance showed the creation of electronically active defects during PECVD deposition process. Interpretation of experimental results was supported by numerical simulation which was developed for computing stationary and transient behaviour of semiconductor devices. Of particular interest was the influence on current density by the bandgap difference between a-Si:H and c-Si leading to a barrier for charge carriers at valence and conduction band. This causes an S-shape of current-voltage curves under illumination at low temperatures. <engl.> In dieser Arbeit wurden Heterodioden aus amorphem (a-Si:H) und kristallinem (c-Si) Silizium untersucht, die Verwendung als Solarzellen finden. Die Laborstrukturen wurden durch Abscheidung von dotiertem a-Si:H auf kristallinen Wafern unter Verwendung von PECVD (Plasma Enhanced Chemical Vapour Deposition) hergestellt. An diesen Heterodioden wurden Strom-Spannungskennlinien temperaturabhängig gemessen. Der Vergleich mit verschiedenen theoretischen Ladungsträgertransportmodellen deutet auf Tunneln von Elektronen durch eine Leitungbandspitze am Heteroübergang und tunnelunterstützte Rekombinationsströme im c-Si. Aus temperatur- und frequenzabhängigen Kapazitätsmessungen ergab sich, dass elektronische aktive Defekte beim PECVD-Prozess entstehen. Zur Unterstützung der Interpretation der Messungen wurde eine numerische Halbleitersimulation entwickelt, mit der sowohl stationäre als auch transiente Vorgänge bei Halbleiterbauelementen berechnet werden können. Besonderes Augenmerk lag auf dem Einfluss auf Stromdichte und Kapazität durch die Energiedifferenz zwischen a-Si:H und c-Si im Leitungs- bzw.

3A550647295.jsonld | Nilmanifolds : complex structures, geometry and deformations | We consider nilmanifolds with left-invariant complex structure and prove that in the generic case small deformations of such structures are again left-invariant. The relation between nilmanifolds and iterated principal holomorphic torus bundles is clarified and we give criteria under which deformations in the large are again of such type. As an application we obtain a fairly complete picture in dimension three. We show by example that the Frölicher spectral sequence of a nilmanifold may be arbitrarily non degenerate thereby answering a question mentioned in the book of Griffith and Harris. On our way we prove Serre Duality for Lie algebra Dolbeault cohomology and classify complex structures on nilpotent Lie algebras with small commutator subalgebra. |

3A1010788590.jsonld | Infinite dimensional affine term structure models under incomplete information | Abstract: The first part of the dissertation extends some important results in the classical theory of finite dimensional affine processes to infinite dimensional separable Hilbert spaces. In particular, a necessary and sufficient condition for a continuous Markov diffusion process to be affine is given. Based on the extended theory, two affine term structure models are introduced and the existence and uniqueness of the two models are studied. The second part concentrates on a non-linear filtering problem with infinite dimensional observations and the Kushner-Stratonovich equation under the infinite dimensional observation setting is derived. Finally, the obtained results are applied to study the Kalman-Bucy filter with infinite dimensional observations. It is proved that the filter has a Gaussian distribution and the evolution equations of the mean and the covariance of the filter are deduced from the Kushner-Stratonovich equation |

Overall low resolution structural models of the entire functional synaptic vesicle are proposed, elucidating details on the density profi le of the membrane, including contributions from the lipids and the proteins, as well as addressing the average conformation and overall lateral organization of proteins in micro-domains on the average synaptic vesicle under quasi-physiological conditions. Entropic contributions to free energy due to possible protein cluster formation and disintegration on the synaptic vesicle are investigated. Further, cell free fusion systems are characterized employing dynamic light scattering and applicability of small-angle x-ray scattering is considered for investigating membrane fusion processes. |
3A1735264342.jsonld | The Magellanic Clouds in VHE gamma rays as seen by H.E.S.S. | The field of gamma-ray astronomy opened a new window into the non-thermal universe that allows studying the acceleration sites of cosmic rays and the role of cosmic rays on evolutionary processes in galaxies. The detection of almost one hundred Galactic very-high-energy (VHE: 0.1−100TeV) gamma-ray sources in the Milky Way demonstrates that particle acceleration up to tens of TeV energies is a common phenomenon. Furthermore, the detection of VHE gamma rays from other galaxies has confirmed that cosmic rays are not exclusively accelerated in the Milky Way. The rapid development of gamma-ray astronomy in the past two decades has led to a transition from the detection and study of individual sources to source population studies. To answer the question, whether the VHE gamma-ray source population of the Milky Way is unique, observations of galaxies, for which individual sources can be resolved, are required.

On this basis, the author shows which elements and mechanisms can be used to reduce the conflicts resulting from the different conceptions of legitimacy in the context of the ongoing legislative development of the regulatory framework for grid-based energy, which is now pending at the national level. Der Verbund unabhängiger Behörden zur Regulierung des europäischen Strombinnenmarktes schafft zahlreiche Herausforderungen für die demokratische Legitimation von Verwaltungstätigkeit. Diesen Problemstellungen widmet sich der Autor in der vorliegenden Untersuchung und stellt dabei zugleich die dem deutschen Grundgesetz und den Unionsverträgen zugrunde liegenden Legitimationskonzepte gegenüber. Davon ausgehend wird aufgezeigt, welche Elemente und Mechanismen eingesetzt werden könne, um die aus den bisherigen unterschiedlichen Legitimationsvorstellungen resultierenden Konflikte im Rahmen der nun auf nationaler Ebene anstehenden gesetzgeberischen Weiterentwicklung des Regulierungsrahmens für leitungsgebundene Energie abzubauen. |
3A830006788.jsonld | Chaotic diffusion in nonlinear Hamiltonian systems | This work investigates diffusion in nonlinear Hamiltonian systems. The diffusion, more precisely subdiffusion, in such systems is induced by the intrinsic chaotic behavior of trajectories and thus is called chaotic diffusion''. Its properties are studied on the example of one- or two-dimensional lattices of harmonic or nonlinear oscillators with nearest neighbor couplings. The fundamental observation is the spreading of energy for localized initial conditions. Methods of quantifying this spreading behavior are presented, including a new quantity called excitation time. This new quantity allows for a more precise analysis of the spreading than traditional methods. Furthermore, the nonlinear diffusion equation is introduced as a phenomenologic description of the spreading process and a number of predictions on the density dependence of the spreading are drawn from this equation. Two mathematical techniques for analyzing nonlinear Hamiltonian systems are introduced. The first one is based on a scaling analysis of the Hamiltonian equation… |
3A1835766781.jsonld | Erzählte Religion : Theologie und Glaube im portugiesischen Roman des 18. Jahrhunderts | Religion bewegte die Menschen im Europa des 18. Jahrhunderts wie kaum ein anderes Thema. Doch wie öffentlich über Religion sprechen, wenn auf der einen Seite die Inquisition jegliche Normabweichung sanktioniert und auf der anderen Seite die Radikalaufklärung Religionskritik propagiert? In diesem aufgeladenen Spannungsfeld bietet die Erzählkunst in Portugal zwischen 1700 und 1800 vielfältige Antworten auf eine der brennendsten Fragen der Zeit. Die vorliegende Studie erschließt ein weitgehend unbekanntes Textkorpus, beleuchtet die omnipräsente Zensur und skizziert anhand exemplarischer Romane von António José da Silva, Sóror Maria do Céu, Teresa Margarida da Silva e Orta und Teodoro de Almeida die Besonderheiten der portugiesischen Erzählentwicklung im europäischen Vergleich.Religion moved people in 18th-century Europe like no other topic. But how to speak publicly about religion when, on the one hand, the Inquisition sanctioned any deviation from the norm and, on the other, the Radical Enlightenment propagated criticism of religion? In this charged field of tension, narrative art in Portugal between 1700 and 1800 offers diverse answers to one of the most burning questions of the time. This study opens up a largely unknown corpus of texts, sheds light on the omnipresent censorship, and outlines the special features of Portuguese narrative development in a European comparison based on exemplary novels by António José da Silva, Sóror Maria do Céu, Teresa Margarida da Silva e Orta, and Teodoro de Almeida. |
3A1822685486.jsonld | An efficient adaptive PD formulation for complex microstructures | The computational costs of newly developed numerical simulation play a critical role in their acceptance within both academic use and industrial employment. Normally, the refinement of a method in the area of interest reduces the computational cost. This is unfortunately not true for most nonlocal simulation, since refinement typically increases the size of the material point neighborhood. Reducing the discretization size while keep- ing the neighborhood size will often require extra consideration. Peridynamic (PD) is a newly developed numerical method with nonlocal nature. Its straightforward integral form equation of motion allows simulating dynamic problems without any extra consideration required. The formation of crack and its propagation is known as natural to peridynamic. This means that discontinuity is a result of the simulation and does not demand any post-processing. As with other nonlocal methods, PD is considered an expensive method. The refinement of the nodal spacing while keeping the neighborhood size (i.e., horizon radius) constant, emerges to several nonphysical phenomena. This research aims to reduce the peridynamic computational and imple- mentation costs. A novel refinement approach is introduced. The pro- posed approach takes advantage of the PD flexibility in choosing the shape of the horizon by introducing multiple domains (with no intersections) to the nodes of the refinement zone. It will be shown that no ghost forces will be created when changing the horizon sizes in both subdomains. The approach is applied to both bond-based and state-based peridynamic and verified for a simple wave propagation refinement problem illustrating the efficiency of the method. Further development of the method for higher dimensions proves to have a direct relationship with the mesh sensitivity of the PD. A method for solving the mesh sensitivity of the PD is intro- duced. The application of the method will be examined by solving a crack propagation problem similar to those reported in the literature. New software architecture is proposed considering both academic and in- dustrial use. The available simulation tools for employing PD will be collected, and their advantages and drawbacks will be addressed. The challenges of implementing any node base nonlocal methods while max- imizing the software flexibility to further development and modification will be discussed and addressed. A software named Relation-Based Sim- ulator (RBS) is developed for examining the proposed architecture. The exceptional capabilities of RBS will be explored by simulating three distinguished models. RBS is available publicly and open to further develop- ment. The industrial acceptance of the RBS will be tested by targeting its performance on one Mac and two Linux distributions. |
3A894844253.jsonld | Executive compensation : three essays on managerial risk-taking, long-term orientation, and convergence in executive compensation | The empirical analyses of data from large German public companies that are presented in this book show that the introduction of long-term orientated remuneration components for corporate executives increases their willingness to invest in riskier investment portfolios, at least in the short term. The study furthermore demonstrates that a payment model which emphasises equity-based remuneration elements is not sufficient to increase executives' long-term orientation. The results of the study’s final analysis show that payment of executives in large German public companies has become more consistent across the board in recent years. |
3A168882104X.jsonld | Die medizinische Indikation als Grundrechtsproblem : zum Informed Consent als Indikationsäquivalent | The medical, legal and social context that justifies the medical indication as a condition for medical action is subject to erosion tendencies. Therefore, there is considerable uncertainty regarding the legal use of the medical indication. The dissertation resolves this uncertainty by means of an innovative medical treatment concept. The constitutional analysis of the medical indication shows that informed consent can basically serve as an indication equivalent. The condition for this is that the legal form of informed consent is further developed in its current form, so that the constitutional result is thus supported. The KAIBRE model for medical treatment developed in this dissertation can be considered a reform option. By distinguishing between indicated, non-indicated and contra-indicated treatment goals and procedures, the decision model reduces the increasing dysfunctionality of informed consent. Der medizinische, rechtliche und gesellschaftliche Kontext, der die medizinische Indikation als Voraussetzung ärztlichen Handelns begründet, unterliegt Erosionstendenzen. Deshalb lässt sich hinsichtlich der rechtlichen Verwendung der medizinischen Indikation eine beachtliche Unsicherheit feststellen. Die Arbeit löst diese Unsicherheit anhand eines innovativen ärztlichen Behandlungskonzepts auf. Die verfassungsrechtliche Analyse der medizinischen Indikation zeigt, dass der Informed Consent grundsätzlich als Indikationsäquivalent dienen kann. Voraussetzung hierfür ist, dass die rechtliche Ausgestaltung des Informed Consent in der jetzigen Form weiterentwickelt und so das verfassungsrechtliche Ergebnis abgestützt wird. Als Reformoption kommt hierfür das in der Arbeit entwickelte KAIBRE-Modell für die ärztliche Behandlung in Betracht. Durch die Unterscheidung zwischen indizierten, nichtindizierten und kontraindizierten Behandlungszielen und Maßnahmen wirkt das Entscheidungsmodell der zunehmenden Dysfunktionalität der Einwilligungsvoraussetzung entgegen. |
