description: Die vorliegende Bachelor-Thesis beschäftigt sich mit der Frage, welchen Stellenwert Hobbys in der Generation Z haben. Die Generation Z umfasst die zwischen 1995 und 2010 Geborenen und somit die heutigen 10- bis 25-Jährigen. Im theoretischen Teil wurde Hintergrundwissen zu den Themen Freizeit, Hobbys und Generation Z geschaffen. Im praktischen Teil wurde eine empirische Untersuchung in Form von qualitativen Interviews durchgeführt. Es wurden insgesamt sieben Vertreter der Generation Z zu dem Thema Hobbys interviewt. Es wurden die Gründe für und gegen das Ausüben von Hobbys, das Verständnis von Hobbys und Unterschiede in der Generation Z an Einzelfällen aufgezeigt.
The Explicit Simplified Interface Method for compressible multicomponent flows

Subjects: subject: Classical Physics (physics.class-ph)

description: This paper concerns the numerical approximation of the Euler equations for multicomponent flows. A numerical method is proposed to reduce spurious oscillations that classically occur around material interfaces. It is based on the "Explicit Simplified Interface Method" (ESIM), previously developed in the linear case of acoustics with stationary interfaces (2001, J. Comput. Phys. 168, pp.~227-248). This technique amounts to a higher order extension of the "Ghost Fluid Method" introduced in Euler multicomponent flows (1999, J. Comput. Phys. 152, pp. 457-492). The ESIM is coupled to sophisticated shock-capturing schemes for time-marching, and to level-sets for tracking material interfaces. Jump conditions satisfied by the exact solution and by its spatial derivative are incorporated in numerical schemes, ensuring a subcell resolution of material interfaces inside the meshing. Numerical experiments show the efficiency of the method for rich-structured flows.

description: Strong isospin breaking in the spectrum of the nucleons and deltas can be studied in lattice QCD with the help of chiral perturbation theory. At leading order in the chiral expansion, the mass splittings between the proton and neutron and between the deltas are linear in the quark mass difference. The next-to-leading order contributions to these splittings vanish even away from the strong-isospin limit. Therefore, any non-linear quark mass dependence of these mass splittings is a signal of the next-to-next-to-leading order mass contributions, thus providing access to LECs at this order. We determine the mass splittings of the nucleons and deltas in two-flavor, heavy baryon chiral perturbation theory to next-to-next-to-leading order. We also derive expressions for the nucleon and delta masses in partially quenched chiral perturbation theory to the same order. The resulting mass expressions will be useful both for the extrapolation of lattice data on baryon masses, and for the study of strong isospin breaking.

description: The Lanthanum Halide scintillator detectors have been widely used for nuclear spectroscopy experiments because of their excellent energy and time resolutions. Despite having these advantages, the intrinsic alpha and beta contaminations in these scintillators pose a severe limitation in their usage in rare-event detections. In the present work, pulse shape discrimination (PSD) with a fast digitizer has been shown to be an efficient method to separate the effect of alpha contamination from the spectrum. The shape of the beta spectrum has been generated with the help of Monte Carlo based simulation code, and its contribution has been eliminated from the spectrum. The reduction in the background events generated by both intrinsic beta and alpha activities has been demonstrated. The present study will encourage the application of these detectors in low cross-section measurement experiments relevant to nuclear astrophysics.

description: Evolving Cascade Neural Networks (ECNNs) and a new training algorithm capable of selecting informative features are described. The ECNN initially learns with one input node and then evolves by adding new inputs as well as new hidden neurons. The resultant ECNN has a near minimal number of hidden neurons and inputs. The algorithm is successfully used for training ECNN to recognise artefacts in sleep electroencephalograms (EEGs) which were visually labelled by EEG-viewers. In our experiments, the ECNN outperforms the standard neural-network as well as evolutionary techniques.

description: Textile traditions are reputed all over the world and admired for their beauty, texture and durability. India has a diverse and rich textile tradition. The origin of Indian textiles can be traced to the Indus valley civilization. The people of this civilization used homespun cotton for weaving their garments. India had numerous trade links with the outside world and Indian textiles were popular in the ancient world. Textile design associates itself in making creative, stylish and contemporary designs. Textile skills to create innovative design require special designs. The theme that has been chosen is blue diamond. Blue diamond is said to the one of the rarest and one of the most valuable gem stone among all of the stones. It is rarest and the most desirable colour. Also known as the hope diamond. The cuts, the shape of the diamond are defined, neat and clean, make it even more beautiful to look at. This fabric is woven with beautiful design on both of its border designs with the help of 16 shafts. Blue and black colour is used in this Stole. Cotton and viscose threads are used in it. Thread count of 2/80s and reed count 80 is used. Diamond design is created on both the side of the Stole. The fabric is consist of both stripe and check on its body. It’s a smooth and fine stole with beautiful black diamond on both border and the blue and black colour looks so attractive and viscose thread increases its shininess.

description: A central challenge in data visualization is to understand which data samples are required to generate an image of a data set in which the relevant information is encoded. In this work, we make a first step towards answering the question of whether an artificial neural network can predict where to sample the data with higher or lower density, by learning of correspondences between the data, the sampling patterns and the generated images. We introduce a novel neural rendering pipeline, which is trained end-to-end to generate a sparse adaptive sampling structure from a given low-resolution input image, and reconstructs a high-resolution image from the sparse set of samples. For the first time, to the best of our knowledge, we demonstrate that the selection of structures that are relevant for the final visual representation can be jointly learned together with the reconstruction of this representation from these structures. Therefore, we introduce differentiable sampling and reconstruction stages, which can leverage back-propagation based on supervised losses solely on the final image. We shed light on the adaptive sampling patterns generated by the network pipeline and analyze its use for volume visualization including isosurface and direct volume rendering.

description: The CV method estimate the monetary value that specific changes in the provision of goods and services represent for society, which is asked for their Willingness To Pay (WTP) for it, according to their budget and individual preferences, in a survey. The applications of CV are a source of information to important public decision-making. Therefore, it seems to be a desirable objective for a CV study to strive to detect and reduce, as far as possible, the bias affecting the elicited values. In the present work, the starting point bias in an application to the case study of the conservation of the Iberian Lynx in Spain is analyzed. This bias is caused by the potential influence of the bid values offered to the interviewees on their stated preferences. Three different but related issues are treated. Firstly, data obtained from a pretest survey are used to generate a bid design that distort as less as possible the real preferences of the population, on the basis of the choice of the starting points and the proportions that will be presented to the interviewees. Secondly, data obtained from the complete survey are analyzed, proving that, in effect, the stated WTP are clearly related to the used starting point. And finally, some carried out simulations show the direction and intensity of the influence of different bid designs on the mean population WTP. Results support the idea of the great importance of the questionnaire design and posterior analysis which enables us to identify and minimize the starting point bias before the estimation of social benefits.

description: The efficiency benefits of U.S. rail industry deregulation are well documented in previous studies of rail productivity and declining rail rates. This research provides new insight regarding the accrual of these benefits within the grain industry. A disaggregate study of corn, wheat, and soybean rates across nine producing regions, shows that in recent years the railroads ability to differentiate markets based on competitive environment has shifted relatively more of the benefit to regions with the most competitive market environments. Regions with less competitive pressure will continue to be relatively more disadvantaged in the rates that are an important determinant in grain market flows and producer profitability if these trends continue.

description: Die Eindämmung der globalen Klimakrise soll über die Reduktion der Treibhausgasemissionen bis hin zur Klimaneutralität erfolgen. Neben dem Ziel, mehr erneuerbare Energien zu integrieren, muss auch das Wasserthema mit betrachtet werden. Energie- und Wasserversorgung stehen in enger Wechselwirkung, aber es fehlen reale und verlässliche Daten zu den Wasserbedarfen von Energiebereitstellungstechnologien. In der vorliegenden Masterthesis werden technologieabhängige Wassernutzungen und -verbräuche untersucht. Leitfrage ist, ob die angestrebten Ausbauziele für die Energiewirtschaft vereinbar mit der Wasserverfügbarkeit in Deutschland sind und welche Folgen sich aus der Energiewende unter Einbezug der Klimafolgen ergeben. Die verwendete Methodik basiert auf der Vorgehensweise einer Ökobilanzierung, erweitert durch eine Nachhaltigkeitsbewertung. Ausgehend von der Beispielregion Bremen wird eine Skalierung auf Deutschland vorgenommen. Die Datengüte für den Wasserbedarf in Bremen unter Einbezug der im Rahmen der vorliegenden Arbeit erhobenen aquatischen Kennzahlen ist mit 0,75 als belastbar einzuschätzen. Auf Basis von Literaturwerten sind die Ergebnisse für Bremen hingegen nur bedingt belastbar (0,375). Bei der Skalierung der Werte für Deutschland ist die Güte mit 0,125 bestimmt, was ebenso eine bedingte Belastbarkeit darstellt. Der Wasserbedarf konnte nicht für alle Energiebereitstellungstechnologien in Bremen erhoben werden. Es wird ökologisch, ökonomisch und sozio-kulturell herausgearbeitet, dass erneuerbare Energiebereitstellungstechnologien und somit auch die Ausbauziele nachhaltiger sind als der aktuelle Energiemix. Fazit der Arbeit ist eine notwendige Verbesserung der Transparenz und Datengrundlage des Wasserbedarfes im Energiesektor. Eine Möglichkeit ist die Integration der aquatischen Kennzahlen als obligatorischer Bestandteil von Umweltberichten von Kraftwerken. Eine weitere Handlungsempfehlung stellt ein deutschlandübergreifend gesteuertes und definiertes, rechtlich bindendes, jährliches Wasserbudget dar. Die Masterarbeit zeigt mögliche Methodiken und die mit zu beachtenden Perspektiven und Kriterien für nachhaltige Wassermanagementsysteme auf. Die Ausarbeitung soll die Aufmerksamkeit auf das Wasserthema richten und erhöhen und zu einer Sensibilisierung aller beteiligten Akteur*innen verhelfen.
Contesting human rights norms in a declining liberal order: China at the Human Rights Council (2017-2022)

description: There seems to be a scholarly consensus around the idea that, in the last decade, China has been actively promoting its own conception of human rights in an attempt to shape global human rights norms. The extent to which China’s views challenge current norms is still unclear, but some suggest they are ultimately aimed at weakening the human rights regime’s ability to hold states accountable for their human rights violations. However, this literature is still scarce and insufficient – most works only rely on a few pieces of adhoc primary empirical evidence or merely analyse existing secondary literature. We still lack a systematic representation of China’s discursive contestation of human rights norms in recent years. This thesis seeks to fill this gap in the literature, asking to what extent China is contesting human rights norms at the Human Rights Council, and more specifically about the main contesting arguments and the main degrees of contestation that China puts forward. My analysis departed from constructivist theories of norm contestation that highlight the different degrees it can take, being able to question the very legitimacy of the norm (validity contestation) or the way it should be implemented (applicatory contestation). Considering this, I conducted a Qualitative Content Analysis of all the available Chinese sponsored and co-sponsored statements and resolutions at the Human Rights Council’s sessions between 2017 and 2022, amounting to a total of 279 documents. The most fiercely contested human rights norms were the monitoring of individual countries’ human rights situations, opposing the legitimacy of this practice in general, but also the specific wrongdoings in its execution, and the idea of universality, contending instead that states have full authority to implement human rights as they wish. The results also show that China made equivalent use of both types of contestation (validity and applicatory), marking a rupture with earlier Chinese discourse, which largely refrained from questioning the legitimacy of human rights norms. This thesis contributes to the literature by constructing a much-needed systematic, comprehensive and empirically grounded description of China’s counter-discourse on human rights norms, which in turn shows that China is posing a very serious challenge to such norms today.

description: Mit voranschreitender Digitalisierung bekommen auch Kinder und Jugendliche immer früher Zugang zu elektronischen Medien. Neben vielfältigen positiven Nutzungsmöglichkeiten besteht auch die Gefahr, dass Kinder und Jugendliche Übergriffe im Internet erfahren. Diese qualitative Forschungsarbeit untersucht die Auswirkungen von sexuellen Übergriffen auf Kinder und Jugendliche zwischen 12 und 17 Jahren im virtuellen Raum. Zudem werden die Annäherungsstrategien der Täter*innen an die Betroffenen untersucht. Zur Datengewinnung wurden fünf Expertinnen und Experten aus Fachberatungsstellen mithilfe eines offenen Leitfadens befragt, die ihren Schwerpunkt auf sexuellen Übergriffen hatten. Die Auswertung erfolgte nach der Methode des thematischen Vergleichs. Die Interviews zeigten, dass die Betroffenen bei sexuellen Übergriffen Schuld, Scham und häufig auch eine Ambivalenz gegenüber den Täterinnen und Tätern empfanden. Neben Cybergrooming wirkte sich auch die ungefragte Bilderweiterleitung im Kontext von einvernehmlichem Sexting negativ auf die Betroffenen aus. Betroffene empfanden den Prozess der Strafverfolgung als retraumatisierend und destabilisierend. Die Täter*innen nutzten im virtuellen Raum eine heterogene Bandbreite an Annäherungsstrategien. Diese Resultate werden vor dem Hintergrund der Integrated Theory of Sexual Offending und der Space Transition Theory diskutiert. Zudem wird die Theorie der sexuellen Skripte als Erklärungsansatz für die Entwicklung von Sexualität herangezogen. Daraus folgend können mögliche Präventionsstrategien abgeleitet werden, mit denen Kinder und Jugendliche über Groomingstrategien aufgeklärt werden. Weiter implizieren die Ergebnisse eine Notwendigkeit für eine Umstrukturierung der Befragungsstrukturen während eines Strafprozesses.

description: Experiments in economics and their application to policy design continue to gain increasing popular appeal. Australia is investing in training, capacity building and international partnerships to bring these skills to our policy makers. Economic experiments are used to test policy-related hypotheses: to examine the behavioural processes upon which the policy is built, identify policy bugs, confirm incentive mechanism performance, investigate new decision processes, and illustrate economic allocation systems to stakeholders. Experiments provide a new source of information to improve policy design. This paper explores a set of experiments conducted for the National Action Plan for Salinity and Water Quality Market Based Instruments Pilots Program. The experiments test bed water and salt markets. The pilot region is the Sunraysia in northern Victoria, Australia. The paper looks at, -How economic experiments can answer policy questions important for field implementation, using the questions posed by stakeholders in Sunraysia. -How economic experiments complement economic theory, using examples from the salinity and water allocation problem in Sunraysia. -Provide examples of other water policy experiments. These experiments address water allocation questions important to Australia. The objective of the paper is to reveal both the strengths and limits of economic experiments for policy. The paper is based on my experiences using experiments for policy design in the role of a research economist for government and as a PhD researcher at University.

description: "Landcare" is a group-based approach to the promotion of conservation farming. A case study of the Landcare program in Lantapan in the southern Philippines is presented to assess the farm-level impacts of this approach. The program was successful in promoting the formation of Landcare groups and a municipal Landcare association, resulting in rapid and widespread adoption of conservation practices, particularly among maize farmers. This in turn significantly reduced soil erosion, though the impact on crop yield and income was somewhat delayed. Adoption was thus not motivated primarily by short-term returns but by a concern to reduce soil erosion and provide a basis for diversification into agroforestry.

description: We present results for a variety of Monte Carlo annealing approaches, both classical and quantum, benchmarked against one another for the textbook optimization exercise of a simple one-dimensional double-well. In classical (thermal) annealing, the dependence upon the move chosen in a Metropolis scheme is studied and correlated with the spectrum of the associated Markov transition matrix. In quantum annealing, the Path-Integral Monte Carlo approach is found to yield non-trivial sampling difficulties associated with the tunneling between the two wells. The choice of fictitious quantum kinetic energy is also addressed. We find that a ``relativistic'' kinetic energy form, leading to a higher probability of long real space jumps, can be considerably more effective than the standard one.

description: Medical imaging is a cornerstone for medical diagnosis, treatment planning, and clinical studies. In order to delineate anatomical structures and other regions of interest in such images, deep neural networks can be employed, performing image segmentation for the medical expert. Because of the high-risk setting, these models need to be not only exact and robust, but also indicate error likelihood via reliable and meaningful uncertainty estimates. This predictive uncertainty can be subdivided into aleatoric and epistemic uncertainty, and captured using deep ensembles, Bayesian neural networks, and additional loss attenuating output neurons. The main contribution of this work is a comprehensive comparison between the direct decomposition of uncertainty in Bayesian neural networks via the mutual information metric and the explicit modelling of epistemic and aleatoric uncertainty in Bayesian neural networks with an additional heteroscedastic loss-attenuating neuron. This comparison is performed in the context of medical image segmentation of the liver from CT scans, employing a 3D au-net as base architecture. The quality of the uncertainty decomposition in the resulting uncertainty maps is qualitatively evaluated and quantitative behaviour of aleatoric and epistemic uncertainty is systematically compared for different experiment settings with varying training set sizes, label noise, and distribution shifts. The results show the mutual information decomposition to robustly yield meaningful aleatoric and epistemic uncertainty estimates, with both largely conforming to their definitions and consistent with other works. Noisiness in the activation of the loss-attenuating neuron leads to the conclusion that the mutual information decomposition remains significantly more suited for uncertainty decomposition even for Bayesian neural networks combined with loss-attenuating neurons. This work further found that the addition of a heteroscedastic neuron does not improve the quality of the uncertainty estimates when decomposed via the mutual information metric. An ancillary contribution is the demonstration of a strong influence of the choice of loss function on the quality of uncertainty decomposition, with soft Dice loss heavily deteriorating the quality of the decomposed uncertainties.

description: In this paper from 2009 we study IL(PRA), the interpretability logic of PRA. As PRA is neither an essentially reflexive theory nor finitely axiomatizable, the two known arithmetical completeness results do not apply to PRA: IL(PRA) is not ILM or ILP. IL(PRA) does of course contain all the principles known to be part of IL(All), the interpretability logic of the principles common to all reasonable arithmetical theories. In this paper, we take two arithmetical properties of PRA and see what their consequences in the modal logic IL(PRA) are. These properties are reflected in the so-called Beklemishev Principle B, and Zambella's Principle Z, neither of which is a part of IL(All). Both principles and their interrelation are submitted to a modal study. In particular, we prove a frame condition for B. Moreover, we prove that Z follows from a restricted form of B. Finally, we give an overview of the known relationships of IL(PRA) to important other interpetability principles.

description: We derive corrections to the JIMWLK equation in the regime where the charge density in the hadronic wave function is small. We show that the framework of the JIMWLK equation has to be significantly modified at small densities in order to properly account for the noncommutativity of the charge density operators. In particular the weight function for the calculation of averages can not be real, but is shown to contain the Wess-Zumino term. The corrections to the kernel of the JIMWLK evolution which are leading at small density are resummed into a path ordered exponential of the functional derivative with respect to the charge density operator, thus hinting at intriguing duality between the high and the low density regimes.

description: Atomic force microscopy (AFM) images give valuable information about surface roughness of thin films based on the results of power spectral density (PSD) through the fast Fourier transform (FFT) algorithms. In the present work, AFM data are studied for silver and gold nanoparticles (Ag NPs a-C: H and Au NPs a-C: H) embedded in amorphous hydrogenated carbon films and co-deposited on glass substrate via of RF-Sputtering and RF-Plasma Enhanced Chemical Vapor Deposition methods. Here, the working gas is acetylene and the targets are Ag and Au. While time and power are constant, the only variable parameter in this study is initial pressure. In addition, the crystalline structure of Ag NPs a-C: H and Au NPs a-C: H are studied using X-ray diffraction (XRD). UV–visible spectrophotometry will also investigate optical properties and localized surface plasmon resonance (LSPR) of samples.

description: Pure and co-doped Titania thin films were prepared on aluminum substrates through the sol-gel method. The co-doped sample showed higher photocatalytic activity on benzene degradation compared to pure TiO2 under visible light illumination. XRD results showed the anatase phase for both TiO2 and co-doped TiO2 lattices with an average crystalline size of 12.9 and 10.4 nm, respectively. According to the UV-visible absorption spectra results, co-doped Titania showed higher visible light absorption compared to pure Titania. The synergistic effect of dopants caused a redshift to visible light absorption and also the lifetime of the photogenerated electron-hole were increased by induced electron levels in Titania lattice. The novelty of this study is the reactor’s specific design. We employed Al mesh as thin film substrate for 3 main reasons, first, the large surface area of the Al mesh causes to increase specific surface area of the photocatalysts, also it is a formable substrate which can be engineered geometrically to decrease the shadow spots so the thin films will receive the highest light irradiation. Also, the Al mesh flexibility facilitates the procedure of reactor design to reach a minimum pressure drop of airflow while it is installed in the air conditioners or HVAC systems

description: The Burton--Keane theorem for the almost-sure uniqueness of infinite clusters is a landmark of stochastic geometry. Let $μ$ be a translation-invariant probability measure with the finite-energy property on the edge-set of a $d$-dimensional lattice. The theorem states that the number $I$ of infinite components satisfies $μ(I\in\{0,1\})=1$. The proof is an elegant and minimalist combination of zero--one arguments in the presence of amenability. The method may be extended (not without difficulty) to other problems including rigidity and entanglement percolation, as well as to the Gibbs theory of random-cluster measures, and to the central limit theorem for random walks in random reflecting labyrinths. It is a key assumption on the underlying graph that the boundary/volume ratio tends to zero for large boxes, and the picture for non-amenable graphs is quite different.

description: During the past two decades, international trade in telecommunication services has significantly intensified. What is more, an increasing number of telecommunications operators have begun to expand their activities beyond national borders through FDIs, joint ventures, and cooperation agreements. In this paper it is argued, however, that in spite of the rather successful efforts of late to liberalize the telecommunications sector (networks and services) at the regional (EU) and the global (WTO) level, much remains to be done to create and preserve a truly open and competitive worldwide telecommunications market. In den vergangenen beiden Jahrzehnten hat sich der internationale Handel mit Telekommunikationsdienstleistungen wesentlich intensiviert. Parallel dazu begannen immer mehr Telefongesellschaften, sich durch Direktinvestitionen, Joint ventures und Kooperationen auch auf ausländischen Märkten zu engagieren. Wie in dem vorliegenden Papier gezeigt wird, kann allen bisherigen Liberalisierungserfolgen der jüngeren Vergangenheit auf regionaler (EU) und globaler Ebene (WTO) zum Trotz von einem offenen globalen Markt für Telekommunikationsdienste und damit auch von einem freien, unverfälschten Wettbewerb zwischen alternativen Netz- und Diensteanbietern noch immer nicht die Rede sein.

description: In this paper we analyze the structure of supersymmetric vacua in compactifications of the heterotic string on certain manifolds with SU(3) structure. We first study the effective theories obtained from compactifications on half-flat manifolds and show that solutions which stabilise the moduli at acceptable values are hard to find. We then derive the effective theories associated with compactification on generalised half-flat manifolds. It is shown that these effective theories are consistent with four-dimensional N=1 supergravity and that the superpotential can be obtained by a Gukov-Vafa-Witten type formula. Within these generalised models, we find consistent supersymmetric (AdS) vacua at weak gauge coupling, provided we allow for general internal gauge bundles. In simple cases we perform a counting of such vacua and find that a fraction of about 1/1000 leads to a gauge coupling consistent with gauge unification.

description: A novel reduction procedure for covariant classical field theories, reflecting the generalized symplectic reduction theory of Hamiltonian systems, is presented. The departure point of this reduction procedure consists in the choice of a submanifold of the manifold of solutions of the equations describing a field theory. Then, the covariance of the geometrical objects involved, will allow to define equations of motion on a reduced space. The computation of the canonical geometrical structure is performed neatly by using the geometrical framework provided by the multisymplectic description of covariant field theories. The procedure is illustrated by reducing the D'Alembert theory on a five-dimensional Minkowski space-time to a massive Klein-Gordon theory in four dimensions and, more interestingly, to the Schrödinger equation in 3+1 dimensions.
