description: Die scham- und ekelbesetzte Begegnung mit alten und kranken Menschen, mit deren psychischen Nöten, mit dem Tod, aber auch der ökonomische Druck sowie der Personalmangel führen dazu, dass Auszubildende während der praktischen Ausbildung oder kurz danach überlegen, ob sie die Ausbildung abbrechen. In einer qualitativen Studie werden emotionale Herausforderungen für Auszubildende untersucht. Dazu werden deren Erlebnisse beschrieben und anhand des pflegewissenschaftlichen und pflegepäda-gogischen Diskurses erklärt und erläutert. Ausgehend von den empirischen Erkenntnis-sen wird ein Konzept skizziert, mit dem Auszubildende entlastet und persönlich ge-stärkt werden könnten: Sie sollen ‚lernen‘, indem sie eigene Erlebnisse reflektieren. Ab-schließend gibt es zu den konzipierten Lerneinheiten didaktisch-methodische Impulse und Umsetzungshinweise, mit denen Lehrende eine reflexionsförderliche Praxisbeglei-tung durchführen könnten.
description: The shameful and disgusting encounter with old and sick people, with their psycholo-gical needs, with death, but also with the economic pressure and lack of staff, lead trainees to consider during the practical education or shortly thereafter whether to drop out. A qualitative study examines emotional pressure for trainees. For this pur-pose, their experiences are described and explained on the basis of the scientific and educational nursing discourse. Based on the empirical findings, a concept is outlined with which trainees could be relieved and personally strengthened: They should 'learn' by reflecting on their own experiences. Finally, there are didactic-methodical impulses and implementation tips for the designed learning units, with which teachers could carry out a practical reflection support.

description: Laminar-turbulent intermittency is intrinsic to the transitional regime of a wide range of fluid flows including pipe, channel, boundary layer and Couette flow. In the latter turbulent spots can grow and form continuous stripes, yet in the stripe-normal direction they remain interspersed by laminar fluid. We carry out direct numerical simulations in a long narrow domain and observe that individual turbulent stripes are transient. In agreement with recent observations in pipe flow we find that turbulence becomes sustained at a distinct critical point once the spatial proliferation outweighs the inherent decaying process. By resolving the asymptotic size distributions close to criticality we can for the first time demonstrate scale invariance at the onset of turbulence.

Publisher: name: Zenodo
Year: 2019

description: The government of Ethiopia is promoting the leather manufacturing sector as a priority subsector and the sector has a huge potential to develop an economy. However; its performance is unsatisfactory due to external and internal problem that hinders its competitiveness in the international market. Thus, the aim of this study was to investigate the effect of determinants on export performance of domestic leather footwear export manufacturing firms in Ethiopia. Determinants of export performance such as product quality, capital, export knowledge, technological capability, global competition and export promotional support were analyzed based on the selected conceptual framework. A quantitative research approach was applied in order to achieve research objectives. The researcher used a purposive sampling technique to select four departments and 9 heads of respondents in each 14 domestic footwear manufacturing firms.
Essays on risk management in times of deepening economic inequality

description: This thesis examines various types of financial risk in the context of empirical economic research and discusses the potential interrelationship between these risks and various aspects of social or economic inequality. In particular, the need for appropriate risk management measures is emphasized to prevent or minimize negative effects of the two variables on each other. Exemplarily, important transmission channels between risk and inequality at micro- and macroeconomic levels are presented and positive effects through risk management measures at the individual, institutional, and governmental level are discussed. This cumulative dissertation contributes a total of eleven research papers on risk management issues -- ten empirical essays and a literature review. The geographical scope of this thesis is predominantly on highly developed industrialized countries. For this reason, sub-analyses are conducted for some of the world's leading economies: the United States, Germany, the United Kingdom, and selected European Monetary Union 'core' and 'non-core' member countries. Basically, the eleven modules are organized into four research clusters, based on different financial risks at micro- and macroeconomic levels: The first cluster shows linkages of risk and inequality within the German pension system. In particular, the invalidity risk and impending funding problems within the statutory pension system will be examined. (Module 1-2) The second cluster highlights inequality as a major driver of the Global Financial Crisis and emphasizes, in particular, the importance of a forward-looking risk management in the real estate sector. (Module 3-6) The third cluster discusses aspects of inequality in the European Economic Union, caused by different credit risks of the member countries in a simultaneous single monetary policy, focusing mainly on the period around the European Sovereign Debt Crisis. (Module 7-9) The fourth cluster presents some thoughts on the linkage between private insurance activity and inequality. (Module 10-11) In summary, this thesis illustrates the need for appropriate risk management to prevent inequality from rising due to higher financial risks (or vice versa). Since those dynamic developments are difficult to control by politics and regulatory authorities alone, the importance of research on risk management issues further increases -- in particular in times of deepening economic inequality.

description: As part of Geoscience Australia’s Exploring for the Future program, this study aims to analyse the hydrocarbon prospectivity in the Carrra Sub-basin through wireline log interpretation and shale gas reservoir characterisation. NDI Carrara 1 is the first stratigraphic test of the Carrara Sub-basin, a recently uncovered depocentre located within the South Nicholson region of the eastern Northern Territory and northwestern Queensland. Four chemostratigraphic packages were defined according to the informal sub-division of stratigraphy and inorganic geochemical properties. Wireline log interpretation has been conducted to derive the clay mineral compositions, porosity, gas saturation and gas contents for the unconventional shale gas reservoirs in the Proterozoic succession in NDI Carrara 1. The predominant clay minerals include illite/muscovite, mixed-layer clay, smectite, kaolinite, and minor contents of glauconite and chlorite. The average geothermal gradient is estimated to be 35.04 °C/km with a surface temperature of 29.4 °C. The average formation pressure gradient is calculated to be < 10.7 MPa/km from mud weight records. Artificial neural network technology is used to interpret the TOC content from wireline logs for unconventional shale gas reservoirs. TOC content is positively correlated with methane and ethane concentrations in mudlog gas profiles, shale porosity, formation resistivity and gas content for NDI Carrara 1. The organic-rich shales in P2 have favourable adsorbed, free and total gas contents. The organic-rich micrites within P3 have the potential in adsorbed gas, but with very low average gas saturation (< 0.01 m3/m3). Our interpretation has identified potential shale gas reservoirs, as well as tight non-organic-rich shales and siltstones with potential as gas reservoirs. These occur throughout several of the identified chemostratigraphic packages within the Proterozoic section of NDI Carrara 1.

description: We investigate constraints on early dark energy (EDE) from the Cosmic Microwave Background (CMB) anisotropy, taking into account data from WMAP9 combined with latest small scale measurements from the South Pole Telescope (SPT). For a constant EDE fraction we propose a new parametrization with one less parameter but still enough to provide similar results to the ones previously studied in literature. The main emphasis of our analysis, however, compares a new set of different EDE parametrizations that reveal how CMB constraints depend on the redshift epoch at which Dark Energy was non negligible. We find that bounds on EDE get substantially weaker if dark energy starts to be non-negligible later, with early dark energy fraction Omega_e free to go up to about 5% at 2 sigma if the onset of EDE happens at z < 100. Tight bounds around 1-2% are obtained whenever dark energy is present at last scattering, even if its effects switch off afterwards. We show that the CMB mainly constrains the presence of Dark Energy at the time of its emission, while EDE-modifications of the subsequent growth of structure are less important.

description: Asset pricing anomalies refer to robust empirical patterns in asset prices and returns which are contradictory to theoretical asset pricing models. This compilation thesis comprises four empirical essays which study selected anomalies from a behavioral perspective and cover the following research topics: The discounts on Closed-End Funds make a strong case for behavioral finance since the stylized fact that two identical cash flows have different prices is hard to reconcile with the law of one price, an important pillar of neoclassical finance. Research in psychology and decision theory suggests that investment decisions of retail investors are subject to a preference for skewness, tantamount to a higher demand for assets with lottery-like payoffs. The first essay introduces the difference between market prices and fundamental values of Closed-End Funds as a novel testing ground to quantify pricing effects of lottery demand. Skewness and economy-wide skewness preferences are a new piece towards solving the Closed-End Fund puzzle and explain variations in discounts above and beyond alternative propositions in the literature. The positive trade-off between risk and return is a second pillar of neoclassical finance. Risk-averse investors accept higher risk only in expectation of higher returns. Empirically, however, the relationship between average returns and the two most widely adopted risk measures volatility and market beta is negative. The three remaining essays of this dissertation propose unaccounted factors as an explanation for the negative expected returns of risky stocks. Each of the three studies proposes novel approaches to quantify latent factors in the investors factor model without a conjecture about the source of unaccounted risk, thus facilitating an ex ante impartial evaluation of existing theories, e.g. short sale constraints or investor sentiment. Although each study proposes a different technical identification strategy, thorough discrimination tests highlight that behaviorally motivated propositions attain the highest explanatory power which is not easily shared by alternative theories. Stocks with high idiosyncratic volatility and high beta are exposed to demand of sentimental investors, so-called noise traders. This unexpected buying pressure inflates prices and causes temporary spikes in volatility, followed by negative expected returns in the near future. The results in this thesis are interesting for future research in empirical finance and investors alike. Each essay pins down adverse effects due to skewness preferences and noise trader demand in aggregate asset prices and thus helps understanding determinants of asset prices and returns.

description: The main purpose of research is to determine the influence by the small dispersive coal dust particles of the different fractional consistence on the technical characteristics of the vertical iodine air filter at nuclear power plant. The research on the transport properties of the small dispersive coal dust particles in the granular filtering medium of absorber in the vertical iodine air filter is completed in the case, when the modeled aerodynamic conditions are similar to the real aerodynamic conditions. It is shown that the appearance of the different fractional consistence of small dispersive coal dust particles with the decreasing dimensions down to the micro and nano sizes at the action of the air dust aerosol stream normally results in a significant change of distribution of the small dispersive coal dust particles masses in the granular filtering medium of an absorber in the vertical iodine air filter, changing the vertical iodine air filter aerodynamic characteristics. The precise characterization of the aerodynamic resistance of a model of the vertical iodine air filter is completed. The comparative analysis of the technical characteristics of the vertical and horizontal iodine air filters is also made.

description: We study the capacity limits of real-time streaming over burst-erasure channels. A stream of source packets must be sequentially encoded and the resulting channel packets must be transmitted over a two-receiver burst-erasure broadcast channel. The source packets must be sequentially reconstructed at each receiver with a possibly different reconstruction deadline. We study the associated capacity as a function of burst-lengths and delays at the two receivers. We establish that the operation of the system can be divided into two main regimes: a low-delay regime and a large-delay regime. We fully characterize the capacity in the large delay regime. The key to this characterization is an inherent slackness in the delay of one of the receivers. At every point in this regime we can reduce the delay of at-least one of the users until a certain critical value and thus it suffices to obtain code constructions for certain critical delays. We partially characterize the capacity in the low-delay regime. Our capacity results involve code constructions and converse techniques that appear to be novel. We also provide a rigorous information theoretic converse theorem in the point-to-point setting which was studied by Martinian in an earlier work.

description: Charge transfer is considered in systems composed of a donor, an acceptor and bridge sites of (AT) nucleotide pairs. For a bridge consisting of 180 (AT) pairs, three cases are dealt with: a uniform case, when all the nucleotides in each strand are identical; an ordered case, when nucleotides in each DNA strand are arranged in an orderly fashion; a chaotic case, when (AT) and (TA) pairs are arranged randomly. It is shown that in all the cases a charge transfer from a donor to an acceptor can take place. All other factors being equal, the transfer is the most efficient in the uniform case, the ordered and chaotic cases are less and the least efficient, accordingly. The results obtained are in agreement with experimental data on long-range charge transfer in DNA.

Planetary nebulae and HII regions in the spiral galaxy NGC 300. Clues on the evolution of abundance gradients and on AGB nucleosynthesis

description: We have obtained deep spectra of 26 planetary nebulae (PNe) and 9 compact HII regions in the nearby spiral galaxy NGC 300, and analyzed them together with those of the giant HII regions previously observed. We have determined the physical properties of all these objects and their He, N, O, Ne, S and Ar abundances in a consistent way. We find that, globally, compact HII regions have abundance ratios similar to those of giant HII regions, while PNe have systematically larger N/O ratios and similar Ne/O and Ar/O ratios. We demonstrate that the nitrogen enhancement in PNe cannot be only due to second dredge-up in the progenitor stars, since their initial masses are around 2--2.5\,\msun. An extra mixing process is required, perhaps driven by stellar rotation. Concerning the radial abundance distribution, PNe behave differently from HII regions: in the central part of the galaxy their average O/H abundance ratio is 0.15 dex smaller. Their abundance dispersion at any galactocentric radius is significantly larger than that shown by HII regions and many of them have O/H values higher than HII regions at the same galactocentric distance. This suggests that not only nitrogen, but also oxygen is affected by nucleosynthesis in the PN progenitors, by an amount which depends at least on the stellar rotation velocity and possibly other parameters. The formal O/H, Ne/H and Ar/He abundance gradients from PNe are significantly shallower that from HII regions. We argue that this indicates a steepening of the metallicity gradient in NGC 300 during the last Gyr, rather than an effect of radial stellar motions, although the large observed dispersion makes this conclusion only tentative.

description: We propose to use an acoustic surface wave as a memory for a photon carrying orbital angular momentum. We clarify the physical mechanism that enables the transfer of information, derive the angular momentum selection rule that must be obeyed in the process, and show how to optimize the optoacoustic coupling. We theoretically demonstrate that high fidelities can be achieved, using realistic parameters, for the transfer of a coherent optical Laguerre-Gaussian state, associated with large angular momentum, to a mechanical shear mode. Our results add a significant possibility to the ongoing efforts towards the implementation of quantum information processing using photonic orbital angular momentum.

description: We provide a theoretical description of the polarization pattern and phase singularities experimentally evidenced recently in a condensate of indirect excitons [H. High et al., Nature 483, 584-588 (2012)]. We show that the averaging of the electron and hole orbital motion leads to a comparable spin-orbit interaction for both type of carriers. We demonstrate that the interplay between a radial coherent flux of bright indirect excitons and the Dresselhaus spin-orbit interaction results in the formation of spin domains and of topological defects similar to Skyrmions. We reproduce qualitatively all the features of the experimental data and obtain polarization pattern as in the optical spin Hall effect despite the different symmetry of the spin-orbit interactions.

description: We consider the formation of solar infrared (2-6 micron) rovibrational bands of carbon monoxide (CO) in CO5BOLD 3D convection models, with the aim to refine abundances of the heavy isotopes of carbon (13C) and oxygen (18O,17O), to compare with direct capture measurements of solar wind light ions by the Genesis Discovery Mission. We find that previous, mainly 1D, analyses were systematically biased toward lower isotopic ratios (e.g., R23= 12C/13C), suggesting an isotopically "heavy" Sun contrary to accepted fractionation processes thought to have operated in the primitive solar nebula. The new 3D ratios for 13C and 18O are: R23= 91.4 +/- 1.3 (Rsun= 89.2); and R68= 511 +/- 10 (Rsun= 499), where the uncertainties are 1 sigma and "optimistic." We also obtained R67= 2738 +/- 118 (Rsun= 2632), but we caution that the observed 12C17O features are extremely weak. The new solar ratios for the oxygen isotopes fall between the terrestrial values and those reported by Genesis (R68= 530, R6= 2798), although including both within 2 sigma error flags, and go in the direction favoring recent theories for the oxygen isotope composition of Ca-Al inclusions (CAI) in primitive meteorites. While not a major focus of this work, we derive an oxygen abundance of 603 +/- 9 ppm (relative to hydrogen; 8.78 on the logarithmic H= 12 scale). That the Sun likely is lighter than the Earth, isotopically speaking, removes the necessity to invoke exotic fractionation processes during the early construction of the inner solar system.

description: This work introduces a highly efficient implementation of the transformer architecture on a Field-Programmable Gate Array (FPGA) by using the \texttt{hls4ml} tool. Given the demonstrated effectiveness of transformer models in addressing a wide range of problems, their application in experimental triggers within particle physics becomes a subject of significant interest. In this work, we have implemented critical components of a transformer model, such as multi-head attention and softmax layers. To evaluate the effectiveness of our implementation, we have focused on a particle physics jet flavor tagging problem, employing a public dataset. We recorded latency under 2 $μ$s on the Xilinx UltraScale+ FPGA, which is compatible with hardware trigger requirements at the CERN Large Hadron Collider experiments.

description: Below the critical temperature $T_c\simeq 600 K$, an iso-structural transition, named $γ$-$α$ transition,can be induced in Cerium by applying pressure. This transition is first-order, and is accompanied by a sizable volume collapse. A conclusive theoretical explanation of this intriguing phenomenon has still not been achieved, and the physical pictures proposed so far are still under debate. In this work, we illustrate zero-temperature first-principle calculations which clearly demonstrate that the $γ$-$α$ transition is induced by the interplay between the electron-electron Coulomb interaction and the spin-orbit coupling. We address the still unresolved problem on the existence of a second low-$T$ critical point, i.e., whether the energetic effects alone are sufficient or not to induce the $γ$-$α$ transition at zero temperature.

On the Computing of the Minimum Distance of Linear Block Codes by Heuristic Methods

description: The evaluation of the minimum distance of linear block codes remains an open problem in coding theory, and it is not easy to determine its true value by classical methods, for this reason the problem has been solved in the literature with heuristic techniques such as genetic algorithms and local search algorithms. In this paper we propose two approaches to attack the hardness of this problem. The first approach is based on genetic algorithms and it yield to good results comparing to another work based also on genetic algorithms. The second approach is based on a new randomized algorithm which we call Multiple Impulse Method MIM, where the principle is to search codewords locally around the all-zero codeword perturbed by a minimum level of noise, anticipating that the resultant nearest nonzero codewords will most likely contain the minimum Hamming-weight codeword whose Hamming weight is equal to the minimum distance of the linear code.

description: We show that a vapor of multilevel atoms driven by far-off resonant laser beams, with possibility of interference of two Raman resonances, is highly efficient for creating parity-time (PT) symmetric profiles of the probe-field refractive index, whose real part is symmetric and imaginary part is anti-symmetric in space. The spatial modulation of the susceptibility is achieved by proper combination of standing-wave strong control fields and of Stark shifts induced by a far-off-resonance laser field. As particular examples we explore a mixture of isotopes of Rubidium atoms and design a PT-symmetric lattice and a parabolic refractive index with a linear imaginary part.
