description: A fundamental task in the analysis of multiple sets of data is the source recovery problem when little is known about the observed data. Real-world applications for this problem include the analysis of medical imaging such as fMRIs, multi-modal disinformation detection, video surveillance, and molecular data fusion, among others. Independent Vector Analysis (IVA) is an ongoing area of research which jointly decomposes multiple datasets to recover latent sources. Since it is formulated within the maximum likelihood (ML) framework, IVA benefits from the exploitation of prior knowledge -- forms of diversity -- in the estimation of its probability density function (PDF). In recent years, application of IVA has grown by the imposition of constraints due to various forms of diversity. By taking advantage of prior information, which is usually known beforehand, the IVA solution improves in performance. An important form of diversity is sparsity. In real-world situations, it is common for latent variables to confound relationships between covariates and impede source recovery, allowing for sparsity assumptions to be made in the IVA solution. If applied to the IVA solution, leveraging known sparsity can reduce the effects of confounding variables, isolating the most important relationships in the observed data. As such, an algorithm which imposes sparsity in the IVA solution is attractive as it may improve separation performance. The challenges we face are determining how to manipulate IVA to impose sparsity and which algorithm to use for sparse estimation. In this thesis, we begin with the background and derivation of IVA and we discuss the way in which we may impose sparsity constraints through the inverse covariance matrix to manipulate the IVA solution. Next, we review three competing techniques for sparse inverse covariance estimation, simulating their performance under varying parameters and demonstrating their strengths and weaknesses. Finally, we impart our accumulated research onto a mathematical framework which allows us to impose sparsity on the IVA solution and develop the IVA-SPICE algorithm whose flagship feature is the graphical lasso algorithm for sparse inverse covariance estimation. Using simulated data, we show that by incorporating sparsity as a form of diversity in IVA, we increase its success when underlying data is sparse, thereby expanding its application in real-world problems.

title: Praxisphasen im Studienfach Bewegung und Sport im internationalen Vergleich
Creators: name: Blaich-Böhm, Julia
Year: 2018

description: Hintergrund: Praxisphasen kommt im Rahmen der hochschulischen Lehramtsausbildung international eine bedeutende Rolle zu. Praktika können sich dabei hinsichtlich ihrer Professionalisierungsabsicht und ihrer konkreten Ausgestaltung unterscheiden. Die vorliegende Arbeit untersucht diese Merkmale bei den Praxisphasen im Lehramtsstudium Bewegung und Sport an drei deutschsprachigen Hochschulen und vergleicht sie miteinander. Methode: Zunächst erfolgt eine theoretisch-hermeneutische Aufarbeitung des Themas mittels eines exemplarischen Überblicks über den Forschungsstand zur Curriculumanalyse bei Praxisphasen und einer Darstellung der aktuellen Literatur zu den relevanten Themenfeldern. Im Hauptteil der Arbeit wird an den drei Hochschulen Universität Wien, Universität Koblenz-Landau und Universität / Pädagogische Hochschule (PH) Bern eine qualitative Inhaltsanalyse der intendierten Curricula zu den Praxisphasen im Lehramtsstudium Bewegung und Sport für allgemeinbildende höhere Schulen vorgenommen. Zunächst wird erhoben, welche Professionalisierungsabsichten die erhobenen Praktika jeweils verfolgen und welche inhaltlichen und strukturell/organisatorischen Ausgestaltungsmerkmale bzw. welche Merkmale der universitären Begleitung sie aufweisen. In einem weiteren Schritt werden die Ergebnisse der jeweiligen Hochschulen miteinander verglichen, und so Gemeinsamkeiten und Unterschiede in der Ausgestaltung der Praxisphasen herausgearbeitet. Ergebnisse: Im Bereich der Professionalisierungsabsichten der Praktika dominieren eindeutig die theoriebezogene Auseinandersetzung mit der Praxis und der Kompetenzerwerb. Während die untersuchten Praktika hinsichtlich der inhaltlichen Ausgestaltung, ihrer zeitlichen Situierung im Studium, ihren Teilnahmevoraussetzungen, ihrer Organisationsform und der fachlichen Zuordnung relativ homogen ausfallen, weisen sie in ihrer Ausgestaltung bei den Schulbesuchen durch universitäre Lehrkräfte, bei der Art von universitären Begleitlehrveranstaltungen und beim Workload teils gravierende Unterschiede auf. Schließlich zeichnen sich für den positiven Abschluss des Praktikums bei einigen Praxisphasen gewisse Kernkriterien ab.
Seizing a window of opportunity: community autonomy and influence in the 2016 Colombian peace process
Creators: name: Rosen, Noah Tobias
Publisher: name: American University
Year: 2023

description: My dissertation research seeks to understand how rural grassroots movements shape the local impacts of a peace deal. Specifically, I ask: What explains variation in community autonomy and influence in local peace implementation? A peace process creates a fragile, volatile political context that poses both threats and opportunities for rural communities impacted by conflict. I hypothesize that variation in the autonomy and influence of communities in a peace process can be explained by their relative levels of ‘regional integration’, defined as the degree of representative functions and legal authority that individual communities delegate to regional organizations. I focus on rural Afro-Colombian movements in the Pacific region of Colombia in the five year period following the signing of the 2016 Colombian peace agreement. I develop controlled comparisons in two regions of the department of Chocó, Atrato and Baudó. In each comparison, I assess the capacity of groups of communities to maintain their autonomy in the face of post-conflict insecurity created by FARC demobilization, and to advance their collective development interests in the participatory peacebuilding program PDET (Territorially-Focused Development Program). Overall, my empirical data suggest that the relative advantages of regional integration – organizational capacity, regional cohesion, external legitimacy – increase the ability of communities to shape local peace outcomes, although these advantages are mitigated to a degree by the tradeoffs of integration, namely democratic deficits and a lack of local independence.
title: SeniorInnentagesbetreuung in ländlichen Regionen
Creators: name: Lederer, Lorenz Josef
Year: 2018

description: Der demographische Wandel in Österreich bedingt ein Älterwerden der Gesellschaft. Diese Entwicklung ist in peripheren ländlichen Regionen durch den verstärkten Weg-zug der jüngeren Generationen besonders stark ausgeprägt. Das Betreuungs- und Freizeitangebot für die Älteren ist gleichzeitig oft schlecht ausgebaut. Altersspezifische Aktivitätsangebote können bei der Schließung dieser Lücke helfen und einen wichtigen Beitrag zu gelingendem Altern leisten. Diese Angebote müssen den regionalen Bedürfnissen der älteren Menschen entsprechen, um angenommen zu werden. Theoretische Ansätze zu erfolgreichem Altern werden in dieser Arbeit unter Bezugnahme auf einen ländlichen Kontext erörtert. Auf Freizeitgestaltung und Ehrenamt im Alter wird ein Fokus gelegt. Die spezifischen Bedürfnisse der über 60-Jährigen in der Kleinregion Waldviertel Nord wurden mittels Fragebogenerhebung erforscht und werden detailliert dargestellt und interpretiert. In Kombination mit der Beschreibung bestehender Best-Practice-Projekte werden auf diese Weise konkrete Handlungsempfehlungen an die Kleinregion Waldviertel Nord abgeleitet.
description: The demographic change in Austria brings about an aging of the society. This development is particularly pronounced in peripheral rural regions due to the increased relocation of younger generations. At the same time, the care and leisure facilities for the elderly are often poorly developed. Age-specific activity offers can help close this gap and can make an important contribution to successful aging. These offers must meet the regional needs of the elderly in order to be accepted. Theoretical approaches to successful aging are discussed in this thesis with reference to a rural context. A focus is on leisure activities and volunteering in seniority. The specific needs of over-60s in the subregion Waldviertel Nord were investigated by questionnaire survey and are presented and interpreted in detail. In combination with the description of existing best practice projects, specific recommendations for action are derived for the subregion Waldviertel Nord.

description: Reasoning with declarative knowledge (RDK) and sequential decision-making (SDM) are two key research areas in artificial intelligence. RDK methods reason with declarative domain knowledge, including commonsense knowledge, that is either provided a priori or acquired over time, while SDM methods (probabilistic planning and reinforcement learning) seek to compute action policies that maximize the expected cumulative utility over a time horizon; both classes of methods reason in the presence of uncertainty. Despite the rich literature in these two areas, researchers have not fully explored their complementary strengths. In this paper, we survey algorithms that leverage RDK methods while making sequential decisions under uncertainty. We discuss significant developments, open problems, and directions for future work.

title: Die Zunahme räumlicher Disparitäten in Japan
Creators: name: Ertl, Julia Desiree
Year: 2018

description: Betrachtet man die gegenwärtige Regionalentwicklung in postindustriellen, kapitalistischen Ländern, wie Japan oder Deutschland, kann man kaum von einer ausgewogenen und gleichwertigen Entwicklung in der Raumordnung sprechen. Tatsächlich führt der Trend zur Globalisierung sowie Urbanisierung und die stark neoliberale Wirtschaftspolitik zu einem Spannungsfeld zwischen ländlich abgehängten Räumen und Metropolregionen, die die wesentlichsten Funktionen Kapital, Produktion und Bevölkerung in sich akkumulieren. Die sukzessiv zunehmende Dichotomie zwischen Stadt und Land wird insbesondere in dem aktuell in Deutschland raumwissenschaftlich geführten Peripherisierungsdiskurs zu einer gewichtigen Thematik erhoben. Diese Arbeit knüpft deshalb an die Ansätze der deutschen Peripherisierungsdebatte an und versucht auf Basis der empirischen Ausübung die Anwendungsfähigkeit dieses Konzepts in einem japanischen Kontext zu eruieren sowie sozial-räumliche Disparitäten zwischen städtischem Wachstum und ländlicher Schrumpfung anhand zweier, ländlich gelegener case studies (Ani, Akita und Ashikita, Kumamoto) ausfindig zu machen.
description: Looking at the present regional development in post-industrial, capitalist countries, such as Japan or Germany, one can hardly speak of a balanced and equal development in spatial planning. In fact, the trend towards globalisation and urbanisation as well as the strongly neoliberal economic policies are causing an area of conflict between rural and metropolitan areas, which accumulate the essential functions capital, production and population. The increasing dichotomy between city and periphery, however, became a major issue, especially in the peripheralisation discourse that is currently being conducted in Germany. Therefore, this paper takes up the approaches of the German peripheralisation debate and tries to elucidate the applicability of this concept in a Japanese context by means of empirical case studies. Moreover, based on these two rural case studies (Ani, Akita and Ashikita, Kumamoto), it tries to locate social-spatial disparities between urban growth and rural shrinkage.

description: Command and control (C&C) is important in an attack. It transfers commands from the attacker to the malware in the compromised hosts. Currently, some attackers use online social networks (OSNs) in C&C tasks. There are two main problems in the C&C on OSNs. First, the process for the malware to find the attacker is reversible. If the malware sample is analyzed by the defender, the attacker would be exposed before publishing the commands. Second, the commands in plain or encrypted form are regarded as abnormal contents by OSNs, which would raise anomalies and trigger restrictions on the attacker. The defender can limit the attacker once it is exposed. In this work, we propose DeepC2, an AI-powered C&C on OSNs, to solve these problems. For the reversible hard-coding, the malware finds the attacker using a neural network model. The attacker's avatars are converted into a batch of feature vectors, and the defender cannot recover the avatars in advance using the model and the feature vectors. To solve the abnormal contents on OSNs, hash collision and text data augmentation are used to embed commands into normal contents. The experiment on Twitter shows that command-embedded tweets can be generated efficiently. The malware can find the attacker covertly on OSNs. Security analysis shows it is hard to recover the attacker's identifiers in advance.

description: Delayed neural field models can be viewed as a dynamical system in an appropriate functional analytic setting. On two dimensional rectangular space domains, and for a special class of connectivity and delay functions, we describe the spectral properties of the linearized equation. We transform the characteristic integral equation for the delay differential equation (DDE) into a linear partial differential equation (PDE) with boundary conditions. We demonstrate that finding eigenvalues and eigenvectors of the DDE is equivalent with obtaining nontrivial solutions of this boundary value problem (BVP). When the connectivity kernel consists of a single exponential, we construct a basis of the solutions of this BVP that forms a complete set in $L^2$. This gives a complete characterization of the spectrum and is used to construct a solution to the resolvent problem. As an application we give an example of a Hopf bifurcation and compute the first Lyapunov coefficient.

description: Neural computation in biological and artificial networks relies on the nonlinear summation of many inputs. The structural connectivity matrix of synaptic weights between neurons is a critical determinant of overall network function, but quantitative links between neural network structure and function are complex and subtle. For example, many networks can give rise to similar functional responses, and the same network can function differently depending on context. Whether certain patterns of synaptic connectivity are required to generate specific network-level computations is largely unknown. Here we introduce a geometric framework for identifying synaptic connections required by steady-state responses in recurrent networks of threshold-linear neurons. Assuming that the number of specified response patterns does not exceed the number of input synapses, we analytically calculate the solution space of all feedforward and recurrent connectivity matrices that can generate the specified responses from the network inputs. A generalization accounting for noise further reveals that the solution space geometry can undergo topological transitions as the allowed error increases, which could provide insight into both neuroscience and machine learning. We ultimately use this geometric characterization to derive certainty conditions guaranteeing a non-zero synapse between neurons. Our theoretical framework could thus be applied to neural activity data to make rigorous anatomical predictions that follow generally from the model architecture.

description: This exploratory study seeks to unearth various notions that restrict freedom of speech, such as cancel culture, online hostility, and self-censorship on social media sites, specifically Instagram. It focuses on how Instagram users are self-censoring around social topics discussed on Instagram, due to the prevalence of cancel culture. Through the employment of in-depth interviews, it looks at the way Instagram affordances assists users in resisting self-censorship, through user agency and the creation of safer spaces. It also outlines other reasons users self-censor on the social media site, and the consequent effect on democracy.

description: We consider a mixture of ultracold bosonic atoms on a one-dimensional lattice described by the XXZ-Bose-Hubbard model, where the tunneling of one species depends on the spin state of a second deeply trapped species. We show how the inclusion of antiferromagnetic interactions among the spin degrees of freedom generates a Devil's staircase of symmetry-protected topological phases for a wide parameter regime via a bosonic analog of the Peierls mechanism in electron-phonon systems. These topological Peierls insulators are examples of symmetry-breaking topological phases, where long-range order due to spontaneous symmetry breaking coexists with topological properties such as fractionalized edge states. Moreover, we identify a region of supersolid phases that do not require long-range interactions. They appear instead due to a Peierls incommensurability mechanism, where competing orders modify the underlying crystalline structure of Peierls insulators, becoming superfluid. Our work show the possibilities that ultracold atomic systems offer to investigate strongly-correlated topological phenomena beyond those found in natural materials.

description: We present an open-source software package called "Hamiltonian Open Quantum System Toolkit" (HOQST), a collection of tools for the investigation of open quantum system dynamics in Hamiltonian quantum computing, including both quantum annealing and the gate-model of quantum computing. It features the key master equations (MEs) used in the field, suitable for describing the reduced system dynamics of an arbitrary time-dependent Hamiltonian with either weak or strong coupling to infinite-dimensional quantum baths. This includes the Redfield ME, the polaron-transformed Redfield ME, the adiabatic ME, the coarse-grained ME, and the universal Lindblad ME. HOQST also includes the stochastic Schrodinger equation with spin-fluctuators. We present an overview of the theories behind the various MEs and provide examples to illustrate typical workflows in HOQST. We present an example that shows that HOQST can provide order of magnitude speedups compared to QuTiP, for problems with time-dependent Hamiltonians. The package is ready to be deployed on high-performance computing (HPC) clusters and is aimed at providing reliable open-system analysis tools for noisy intermediate-scale quantum (NISQ) devices. The HOQST Github repository (https://github.com/USCqserver/OpenQuantumTools.jl) provides the starting point for users. Detailed information can be found in the README file.

description: Multicomponent quantum Hall effect, under the interplay between intercomponent and intracomponent correlations, leads us to new emergent topological orders. Here, we report the theoretical discovery of fractional quantum hall effect of strongly correlated Bose-Fermi mixtures classified by the $\mathbf{K}=\begin{pmatrix} m & 1\\ 1 & n\\ \end{pmatrix}$ matrix (even $m$ for boson and odd $n$ for fermion), using topological flat band models. Utilizing the state-of-the-art exact diagonalization and density-matrix renormalization group methods, we build up the topological characterization based on three inherent aspects: (i) topological $(mn-1)$-fold ground-state degeneracy equivalent to the determinant of the $\mathbf{K}$ matrix, (ii) fractionally quantized topological Chern number matrix equivalent to the inverse of the $\mathbf{K}$ matrix, and (iii) two parallel-propagating chiral edge branches with level counting $1,2,5,10$ consistent with the conformal field theory description.

subject: Media industry studies

description: This exploratory study seeks to unearth various notions that restrict freedom of speech, such as cancel culture, online hostility, and self-censorship on social media sites, specifically Instagram. It focuses on how Instagram users are self-censoring around social topics discussed on Instagram, due to the prevalence of cancel culture. Through the employment of in-depth interviews, it looks at the way Instagram affordances assists users in resisting self-censorship, through user agency and the creation of safer spaces. It also outlines other reasons users self-censor on the social media site, and the consequent effect on democracy.
title: Welche Rolle spielte die Dimension der Protection of Civilians bei den UN- Missionen in Sierra Leone?
Creators: name: Bussi, Désirée
Year: 2018

description: Die vorliegende Masterarbeit gibt Auskunft über die Rolle des Protection of Civilians Ansatzes während den UN- Missionen in Sierra Leone. Dabei wurden die relevanten Mandate durch eine systematische Literaturanalyse inhaltlich untersucht. Der theoretische Rahmen, genauer die Schutzkonzepte der Sicherheitsdebatte und Grundlagen der Vereinten Nationen, bilden die Basis der Analyse. Folgend wird genauer auf die Ursachen und den Verlauf des Bürgerkrieges in Sierra Leone eingegangen, um eine Basis für die folgenden Lösungsansätze seitens der internationalen Gemeinschaft zu schaffen. Die Mandate UNAMSIL, UNIOSIL und UNIPSIL wurden dabei in thematische Blöcke eingeteilt und mit den passenden Schutzkonzepten zusammengeführt. Es wurde festgestellt, dass der Schutz von Zivilisten die Grundlage bildet, um langfristige Sicherheit der Bevölkerung, Demokratie und Menschenrechte zu sichern und somit kurz die menschliche Sicherheit garantiert.
description: This Master's thesis examines the role of the Protection of Civilians approach during the UN missions in Sierra Leone after the civil war. The relevant mandates were examined by means of a systematic literature analysis. The theoretical framework, more precisely the security concepts of the security debate and the foundations of the United Nations, form the basis of the analysis. Subsequently, the causes and course of the civil war in Sierra Leone are discussed in order to provide a fundament for the implemented solutions by the international community. The mandates UNAMSIL, UNIOSIL and UNIPSIL were divided into thematic blocks and merged with the appropriate protection concepts. The analysis showed that the protection of civilians forms the basis for ensuring long-term security of the population, democracy and human rights, thus guaranteeing human security.
Kinetic Factors in Affine Quantization and Their Role in Field Theory Monte Carlo

description: Affine quantization, which is a parallel procedure with canonical quantization, needs to use its principal quantum operators, most simply $D=(PQ+QP)/2$ and $Q\neq0$, to represent appropriate kinetic factors, normally $P^2$, which involve only one canonical quantum operator. The need for this requirement stems from the quantization of selected problems that require affine quantization to achieve valid Monte Carlo results. This task is resolved for introductory examples as well as examples that involve scalar quantum field theories.

title: Holocaust-Wahrnehmung muslimischer Jugendlicher in Österreich
Creators: name: Mohammad, Assad Soma
Year: 2018

description: Das Geschichtsverständnis des Holocaust bei muslimischen Jugendlichen stellt in Österreich einen kaum erforschten Untersuchungsgegenstand dar. Das Ziel dieser Arbeit ist daher die Untersuchung der Holocaust-Wahrnehmung muslimischer Jugendlicher. Der erste Teil der Arbeit zeichnet die Funktion von Geschichte als Integrationsmaßstab, die Entwicklung des österreichischen und europäischen Gedächtnisses über den Holocaust und deren Auswirkungen auf die pädagogische Konzeption für den österreichischen Geschichtsunterricht nach. Der zweite Teil beschäftigt sich mit der selbstständig erhobenen, empirischen Untersuchung, für die problemzentrierte Interviews mit fünfzehn Jugendlichen in Wien durchgeführt wurden. Im Schlussteil werden anhand der Untersuchungsergebnisse Schlüsse für eine kritische historisch-politische Bildungsarbeit über den Holocaust gezogen.
description: Since there is a lack of research in Austria, when it comes to the historical understanding of the Holocaust by muslim youth, this paper analyses their perception of the Holocaust. The first part investigates the role of history as an objective of inclusion into society, the unfolding of the Austrian and European memory on the Holocaust and its impacts on history didactics and history lessons in school. The second part of this paper engages in the self-conducted study with fifteen young adults in Vienna. Based on the research results the last chapter concludes with perspectives for a critical historic-political educational work on the Holocaust in Austria.

description: Mechanical systems (i.e., one-dimensional field theories) with constraints are the focus of this paper. In the classical theory, systems with infinite-dimensional targets are considered as well (this then encompasses also higher-dimensional field theories in the hamiltonian formalism). The properties of the Hamilton-Jacobi (HJ) action are described in details and several examples are explicitly computed (including nonabelian Chern-Simons theory, where the HJ action turns out to be the gauged Wess-Zumino-Witten action). Perturbative quantization, limited in this note to finite-dimensional targets, is performed in the framework of the Batalin-Vilkovisky (BV) formalism in the bulk and of the Batalin-Fradkin-Vilkovisky (BFV) formalism at the endpoints. As a sanity check of the method, it is proved that the semiclassical contribution of the physical part of the evolution operator is still given by the HJ action. Several examples are computed explicitly. In particular, it is shown that the toy model for nonabelian Chern-Simons theory and the toy model for 7D Chern-Simons theory with nonlinear Hitchin polarization do not have quantum corrections in the physical part (the extension of these results to the actual cases is discussed in the companion paper [arXiv:2012.13983]). Background material for both the classical part (symplectic geometry, generalized generating functions, HJ actions, and the extension of these concepts to infinite-dimensional manifolds) and the quantum part (BV-BFV formalism) is provided.
