title: Schottische Unabhängigkeitsbestrebungen
Creators: name: Zimmermann, Klaus- Lukas
Year: 2014

description: Schottland will die Unabhängigkeit. Das Jahr 2014 soll die Entscheidung in Form eines Referendums bringen. Auf nationaler und europäischer Ebene gibt es unterschiedliche Haltungen über die Fragen zu einer möglichen Unabhängigkeit. Die Masterarbeit analysiert sowohl die Debatten auf nationaler als auch auf europäischer Ebene über die schottischen Unabhängigkeitsbestrebungen unter besonderer Berücksichtigung des geplanten Referendums 2014. Mit Hilfe vielfältiger Begriffsdefinitionen wie der Freiheit, der schottischen Auffassung des Nationalismus und auch dem Selbstbestimmungsrecht aus völkerrechtlicher Sicht, werden die theoretischen Aspekte die einzelnen Positionen aus der internationalen Politik zusammen. Das Kapitel zum politischen System geht nach allgemeinen Informationen den historischen Kampf der Schotten gegen die Engländer nach. Die Geschichte ist durch den Nationalhelden William Wallace geprägt, der durch seine militärischen Erfolge, so etwas wie ein schottisches Nationalgefühl entwickelte. Nach der eingegangenen Personalunion mit England, kam das Land immer mehr in die englische Abhängigkeit und der schottische Weg war dem englischen gleich. Durch die Kritische Diskursanalyse (KDA) werden einzelne Positionen analysiert. Ziel der KDA ist es u.a. ideologische Fragen und Machtstrukturen zu klären. Unterteilt in nationale und europäische Fragestellungen, analysiere ich Reden die sowohl Pro als auch Contra der Unabhängigkeit sind. Die erzielten Forschungsergebnisse zeigen eine weitgehend zerstrittene politische Landschaft voll unterschiedlicher Erwartungen und Tatsachen. Eine Prognose wie das Referendum ausgeht, ist auch auf Basis dieser Forschungserkenntnisse nicht möglich. Vielmehr soll ein Eindruck der Situation kurz vor der Volksabstimmung wiedergegeben werden.

Political conflict in Cambodia, 1975-1998: Explaining the absence of peace
Creators: name: Rae, James Deshaw
Publisher: name: American University
Year: 2023

description: Violent political conflict in Cambodia has persisted for over thirty years despite a 1991 UN-brokered peace agreement. A 1975-1989 neorealist period created a hostile domestic environment, causing a cycle of violence. The regional balance of power, the acceptability of the use of force, and the primacy of nation-state actors caused this cycle. Hard-line, militaristic domestic political leaders ascended because of foreign patronage, and are inherently unwilling to compromise. This combination has sustained the top-down authoritarian approach to political rule, which has concomitantly retarded the organic growth of non-violent civil society. The post-Cold War international neoliberal shift was flawed. The colonially-constructed state and the externally-driven cycle of violence have weakened traditional royal authority and legitimacy. International negotiations ignored the domestic context and the need to build trust between individuals and groups. Thus, foreign institution-building is an incomplete step towards conflict resolution which must also address domestic political methods, local socioeconomic conditions, and indigenous culture.

Disentangling enantiosensitivity from dichroism using bichromatic fields

description: We discuss how tensorial observables, available in photoelectron angular distributions resulting from interaction between isotropic chiral samples and cross polarized $ω$-$2ω$ bichromatic fields, allow for chiral discrimination without chiral light and within the electric-dipole approximation. We extend the concept of chiral setup [Phys. Rev. A 98, 063428 (2018)], which explains how chiral discrimination can be achieved in the absence of chiral light, to the case of tensorial observables. We derive selection rules for the enantiosensitivity and dichroism of the $b_{l,m}$ coefficients describing the photoelectron angular distribution valid for both weak and strong fields and for arbitrary $ω$-$2ω$ relative phase. Explicit expressions for simple perturbative cases are given. We find that, besides the dichroic non-enantiosensitive [J. Chem. Phys. 151 074106 (2019)], and dichroic-and-enantiosensitive $b_{l,m}$ coefficients found recently [Phys. Rev. A 99, 063406 (2019)], there are also enantiosensitive non-dichroic $b_{l,m}$ coefficients. These reveal the molecular enantiomer independently of the relative phase between the two colors and are therefore observable even in the absence of stabilization of the $ω$-$2ω$ relative phase.

On the molecular information revealed by photoelectron angular distributions of isotropic samples

Year: 2020
Subjects: subject: Atomic Physics (physics.atom-ph)

description: We propose an alternative approach to the description and analysis of photoelectron angular distributions (PADs) resulting from isotropic samples in the case of few-photon absorption via electric fields of arbitrary polarization. As we demonstrate for the one- and two-photon cases, this approach reveals the molecular frame information encoded in the $b_{l,m}$ expansion coefficients of the PAD in a particularly clear way. Our approach does not rely on explicit partial wave expansions of the scattering wave function and the expressions we obtain are therefore interpreted in terms of the vector field structure of the photoionization dipole $\vec{D}(\vec{k})$ as a function of the photoelectron momentum $\vec{k}$. This provides very compact expressions that reveal how molecular rotational invariants couple to the setup (electric field polarization and detectors) rotational invariants. We rely heavily on this approach in a companion paper on tensorial chiral setups. Here we apply this approach to one-photon ionization and find that while $b_{0,0}$ depends only on the magnitude of $\vec{D}(\vec{k})$, $b_{1,0}$ (non-zero for chiral molecules) is sensitive only to the components of $\vec{D}(\vec{k})$ perpendicular to $\vec{k}$ encoded in the propensity field $\vec{B}(\vec{k})\equiv i\vec{D}^{*}(\vec{k})\times\vec{D}(\vec{k})$, and $b_{2,0}$ is sensitive only to the the component of $\vec{D}(\vec{k})$ along $\vec{k}$. We also analyze the resonantly enhanced two-photon case where we show that $b_{0,0}$ and $b_{1,0}$ can be written in terms of an effectively stretched $\vec{D}(\vec{k})$, and that $b_{1,0}$ and $b_{3,0}$ reveal structural information of the field $\vec{B}(\vec{k})$ encoded in three of its vector spherical harmonic expansion coefficients.

The role of the calcium-sensing receptor in longitudinal bone growth
Creators: name: Darby, Janine Massa
Publisher: name: American University
Year: 2023

description: In 1997, W. Chang and colleagues detected the expression of calcium-sensing receptors (CaRs) in articular and growth plate cartilage. They observed that a high extracellular calcium concentration suppresses cartilage nodule formation and matrix production in chondrogenic cell lines. Based on these findings, I hypothesized that the CaR in growth plate cartilage will be activated at increasing concentrations of extracellular calcium causing inhibition of longitudinal bone growth. To test this hypothesis, fetal rat metatarsals on embryonic day 20 were cultured in serum-free medium with 0.3-3 mM calcium (Ca$\sp{2+}$) or 100 $\mu$M gadolinium (Gd$\sp{3+}$). This organ culture system was chosen over cell culture in order to maintain cellular interactions within the growth plate. I assessed the effects of these ions on the rate of longitudinal bone growth, cell proliferation, and quantitative histology. Increased extracellular calcium concentration decreased chondrocyte proliferation and hypertrophy, but increased ossification. This caused suppression of longitudinal bone growth. Thus, CaR may be a physiological regulator of bone growth, inhibiting chondrogenesis and activating ossification.

Creators: name: Hofmann, Monika
Year: 2014

description: Die gegenständliche Arbeit analysiert Alltagsrealitäten im Siglo de Oro anhand der Ausgestaltung des Schlüssels in Don Pedro Calderón de la Barcas Werk El escondido y la tapada. Als Legitimation für den Zusammenhang von Literatur und Gesellschaft bedient sich die Analyse der Theorie des literarischen Felds von Pierre Bourdieu: Der Habitus des Autors fließt in das Werk ein und illustriert das kulturelle Umfeld. Darüber hinaus wird ein Habitus der Figuren, der auf Nachahmung realer Welt im Theater basiert, analog angenommen. Der Schlüssel ist ein Medium, mit dem Grenzen überschritten werden können. Daraus abgeleitet wurde eine Analysemethode anhand von Gegensatzpaaren ausgewählt. Die historischen Gegebenheiten zeigen Bereiche, in denen Grenzen und deren Überschreitungen denkbar sind. Die Grenzen wurden in physische und reale soziale Grenzen sowie imaginäre soziale und emotionale Grenzen geteilt. Erstere behandeln räumliche Grenzen, den Schlüsselbesitz, Bereichsgrenzen und deren Ableitungen (z.B. Miete). Letztere behandeln Rollenbilder, das Machtverständnis, Paarbeziehungen und Emotionen. Bei beiden Grenzen wird auch die Symbolhaftigkeit erörtert. Als Ergebnis kann festgestellt werden, dass der Schlüssel sowohl im Bereich der realen sozialen Grenzen, als auch im Bereich der imaginären Grenzen als Medium der Grenzüberschreitung verwendet wird. Lediglich die Grenze zwischen dem geheimen und bekannten Bereich kann nicht mit dem Schlüssel überschritten werden, da hierfür die Kenntnis der geheimen Tür notwendig ist. Zudem ist der Schlüssel im Werk ein Symbol für Macht, Prüfung, Liebe, Begierde, Eifersucht und Vertrauen. Als sozialhistorische Erkenntnisse können die Existenz einer casa principal und deren Ausgestaltung sowie verschiedene Rechtsinstitute nachgewiesen werden. Außerdem zeigen sich im Werk anhand der Symbolik des Schlüssels Nachweise für die Individualisierung des Menschen, die Ausformung von Liebesbeziehungen und die Überschreitung von Rollenbildern.

description: This paper focuses on channel prediction techniques for massive multiple-input multiple-output (MIMO) systems. Previous channel predictors are based on theoretical channel models, which would be deviated from realistic channels. In this paper, we develop and compare a vector Kalman filter (VKF)-based channel predictor and a machine learning (ML)-based channel predictor using the realistic channels from the spatial channel model (SCM), which has been adopted in the 3GPP standard for years. First, we propose a low-complexity mobility estimator based on the spatial average using a large number of antennas in massive MIMO. The mobility estimate can be used to determine the complexity order of developed predictors. The VKF-based channel predictor developed in this paper exploits the autoregressive (AR) parameters estimated from the SCM channels based on the Yule-Walker equations. Then, the ML-based channel predictor using the linear minimum mean square error (LMMSE)-based noise pre-processed data is developed. Numerical results reveal that both channel predictors have substantial gain over the outdated channel in terms of the channel prediction accuracy and data rate. The ML-based predictor has larger overall computational complexity than the VKF-based predictor, but once trained, the operational complexity of ML-based predictor becomes smaller than that of VKF-based predictor.

description: Previous studies on shareholder reaction to layoff announcements have concentrated on American stock markets. This paper extends research to shareholder reactions on the Frankfurt Stock Exchange during the years 1990 to 1996. Using event study methodology and daily return data from the Karlsruher Kapitalmarktdatenbank, the shares of 30 firms are tested for abnormal returns on and around the day of a layoff announcement. Daily abnormal returns were found to be significant and negative for the announcement day itself and the days just prior to it. Cumulative abnormal returns were found to be significant and negative for the ten days preceding the announcement and significant and positive for the ten days following the announcement. These results suggest that while layoffs are generally perceived as bad news by investors in Germany, they are also seen as a sign that a company is heading in the right direction.

description: Active matter encompasses different nonequilibrium systems in which individual constituents convert energy into non-conservative forces or motion at the microscale. This review provides an elementary introduction to the role of topology in active matter through experimentally relevant examples. Here, the focus lies on topological defects and topologically protected edge modes with an emphasis on the distinctive properties they acquire in active media. These paradigmatic examples represent two physically distinct classes of phenomena whose robustness can be traced to a common mathematical origin: the presence of topological invariants. These invariants are typically integer numbers that cannot be changed by continuous deformations of the relevant order parameters or physical parameters of the underlying medium. We first explain the mechanisms whereby topological defects self propel and proliferate in active nematics, leading to collective states which can be manipulated by geometry and patterning. Possible implications for active microfluidics and biological tissues are presented. We then illustrate how the propagation of waves in active fluids and solids is affected by the presence of topological invariants characterizing their dispersion relations. We discuss the relevance of these ideas for the design of robotic metamaterials and the properties of active granular and colloidal systems. Open theoretical and experimental challenges are presented as future research prospects.

description: A powerful tool for analyzing and approximating the singular values and eigenvalues of structured matrices is the theory of GLT sequences. By the GLT theory one can derive a function, which describes the singular value or the eigenvalue distribution of the sequence, the latter under precise assumptions. However, for small values of the matrix size of the considered sequence, the approximations may not be as good as it is desirable, since in the construction of the GLT symbol one disregards small norm and low-rank perturbations. On the other hand, LFA can be used to construct polynomial symbols in a similar manner for discretizations, where the geometric information is present, but the small norm perturbations are retained. The main focus of this paper is the introduction of the concept of sequence of "Toeplitz momentary symbols", associated with a given sequence of truncated Toeplitz-like matrices. We construct the symbol in the same way as in the GLT theory, but we keep the information of the small norm contributions. The low-rank contributions are still disregarded, and we give an idea on the reason why this is negligible in certain cases and why it is not in other cases, being aware that in presence of high nonnormality the same low-rank perturbation can produce a dramatic change in the eigenvalue distribution. Moreover, a difference with respect to the LFA symbols is that GLT symbols and Toeplitz momentary symbols are more general and are applicable to a larger class of matrices. We show the applicability of the approach which leads to higher accuracy in some cases when compared with the GLT symbol. Finally, since for many applications and their analysis it is often necessary to consider non-square Toeplitz matrices, we formalize and provide some useful definitions, applicable for non-square Toeplitz momentary symbols.

description: Die vorliegende Arbeit beschäftigt sich mit dem Thema „Beginn Erster Weltkrieg“ im Schulbuch. Es wird also erforscht, wie dieses Schulbuchkapitel in Geschichteschulbüchern seit 1927 darstellt wird. Neben dieser diachronen Schulbuchanalyse werden auch vier aktuell approbierte Lehrwerke näher zu der Thematik beleuchtet. Weiters erfolgt zum Hauptteil der Arbeit eine Analyse über die Schulbuchforschung und Lehrpläne seit 1900. Darüber hinaus soll anhand von drei Thesen der Beginn des Ersten Weltkrieges („Die Julikrise“) dem Leser näher gebracht werden. Methodisch bedient sich die Diplomarbeit einer Schulbuchanalyse. Die zehn Lehrwerke werden zunächst einer deskriptiv-quantitativen Grobanalyse durchzogen. Die Analyse basiert zum Großteil auf dem „Salzburger Raster“ von Astleitner u.a. (1998), danach erfolgt eine Feinanalyse anhand von Forschungsfragen die von mir im Vorfeld der Untersuchung aufgestellt wurden. Dieser Teil der Arbeit baut methodisch auf die qualitative Inhaltsanalyse auf. Schlussfolgernd lässt sich feststellen, dass sich die Hauptthesen nach eingehender Analyse bestätigt haben. Sie lauten wie folgt: - Der Beginn des Ersten Weltkrieges wird im Zeitverlauf in Geschichteschulbüchern unterschiedlich dargestellt. - Schulbücher unterliegen in gewisser Weise der Politik und entsprechen dem gerade vorherrschenden Zeitgeist. - Auch aktuelle Lehrwerke des Unterrichtsfaches Geschichte werden von den AutorInnen geformt und vertreten nicht dieselbe Meinung. - Der Stellenwert des Ersten Weltkrieges in der Schulbuchforschung hinkt anderen Themen hinterher.
Assay for detection of mtDNA polymorphisms using peptide nucleic acids and capillary electrophoresis with laser-induced fluorescence
Creators: name: Pyatski, Yelena

Year: 2023

description: A fast, reliable assay was developed for identification of a polymorphism at position 16126 ($\rm T\to C$), in the hypervariable region 1 of the human mitochondrial genome, using peptide nucleic acids (PNAs) labeled with 6-FAM, capillary electrophoresis as a separation technique with laser induced fluorescence detection. This study involved optimization of parameters critical to DNA/PNA hybridization, including sodium ion concentration, concentration of PCR product, injection parameters and hybridization time variation. The extreme specificity of DNA/PNA hybridization was verified by experimentation. Simultaneous detection and confirmation of the nucleotide at position 16126 was achieved by multiplexing PCR products of different size and base composition. Decreasing the length of PCR amplified fragment reduced the analysis time. The application of this assay can be extended to simultaneous identification of several polymorphisms in HV1 or HV2 regions. Developed method can be improved by using dual wavelength in conjunction with ROX and FAM labeled PNA probes. (Abstract shortened by UMI.).

description: The paper deals with the hitherto neglected topic of audio dequantization. It reviews the state-of-the-art sparsity-based approaches and proposes several new methods. Convex as well as non-convex approaches are included, and all the presented formulations come in both the synthesis and analysis variants. In the experiments the methods are evaluated using the signal-to-distortion ratio (SDR) and PEMO-Q, a perceptually motivated metric.

description: A fast, reliable assay was developed for identification of a polymorphism at position 16126 ($\rm T\to C$), in the hypervariable region 1 of the human mitochondrial genome, using peptide nucleic acids (PNAs) labeled with 6-FAM, capillary electrophoresis as a separation technique with laser induced fluorescence detection. This study involved optimization of parameters critical to DNA/PNA hybridization, including sodium ion concentration, concentration of PCR product, injection parameters and hybridization time variation. The extreme specificity of DNA/PNA hybridization was verified by experimentation. Simultaneous detection and confirmation of the nucleotide at position 16126 was achieved by multiplexing PCR products of different size and base composition. Decreasing the length of PCR amplified fragment reduced the analysis time. The application of this assay can be extended to simultaneous identification of several polymorphisms in HV1 or HV2 regions. Developed method can be improved by using dual wavelength in conjunction with ROX and FAM labeled PNA probes. (Abstract shortened by UMI.).

description: A plethora of contact tracing apps have been developed and deployed in several countries around the world in the battle against Covid-19. However, people are rightfully concerned about the security and privacy risks of such applications. To this end, the contribution of this work is twofold. First, we present an in-depth analysis of the security and privacy characteristics of the most prominent contact tracing protocols, under both passive and active adversaries. The results of our study indicate that all protocols are vulnerable to a variety of attacks, mainly due to the deterministic nature of the underlying cryptographic protocols. Our second contribution is the design and implementation of SpreadMeNot, a novel contact tracing protocol that can defend against most passive and active attacks, thus providing strong (provable) security and privacy guarantees that are necessary for such a sensitive application. Our detailed analysis, both formal and experimental, shows that SpreadMeNot satisfies security, privacy, and performance requirements, hence being an ideal candidate for building a contact tracing solution that can be adopted by the majority of the general public, as well as to serve as an open-source reference for further developments in the field.

description: Artificial Intelligence (AI) governance regulates the exercise of authority and control over the management of AI. It aims at leveraging AI through effective use of data and minimization of AI-related cost and risk. While topics such as AI governance and AI ethics are thoroughly discussed on a theoretical, philosophical, societal and regulatory level, there is limited work on AI governance targeted to companies and corporations. This work views AI products as systems, where key functionality is delivered by machine learning (ML) models leveraging (training) data. We derive a conceptual framework by synthesizing literature on AI and related fields such as ML. Our framework decomposes AI governance into governance of data, (ML) models and (AI) systems along four dimensions. It relates to existing IT and data governance frameworks and practices. It can be adopted by practitioners and academics alike. For practitioners the synthesis of mainly research papers, but also practitioner publications and publications of regulatory bodies provides a valuable starting point to implement AI governance, while for academics the paper highlights a number of areas of AI governance that deserve more attention.

description: Does gender-personality among soldiers lead to better adjustment, defined in terms of psychological well-being, perceived combat effectiveness, and perceived social support, i.e. cohesion? In the current study, the contribution of gender-related personality, as measured by the Extended Personal Attributes Questionnaire (EPAQ), hostility towards women, as indicated by the Hostility Towards Women Scale and Acceptance of Women Scale, on combat readiness, horizontal cohesion and vertical cohesion were assessed. Findings indicate that well adapted soldiers endorse items relating to positive masculinity and positive femininity, as well as positive feelings toward working with women. Soldiers considered to be well adapted to the military were less likely to endorse items relating to negative masculinity, negative femininity and hostility towards women.
Preregistration for Attitudes Toward Abortion in Germany: Moral Values, Political Attitudes, and Religiousness

description: Abortion is a polarizing socio-political issue. Attitudes towards abortion have been investigated in the context of various predictors. In the present study, attitudes towards abortion are investigated in the context of moral values, political ideology, and religiosity. In previous studies, only the endorsement of purity, conservatism, and religiosity consistently predicts disapproval of abortion. For other possible predictors (care, fairness, loyalty, authority, or liberty), there is inconsistent evidence: for each dimension there are studies which find it a predictor of approval, of disapproval, or to be non-significant. If significant, the direction of correlation (positive vs. negative) varies between studies. Further, there are national differences in legislation and cultural differences across countries, making generalisation of findings from one country to other countries a question of empirical research. The present study aims to address several gaps in the current empirical literature: Objective 1: Investigate how religiosity and political ideology mediate the relationship between moral values and attitudes towards abortion in Germany; Objective 2: Determine if attitudes towards abortion are multi-dimensional; Objective 3: Explore the (in-)dependence of the ATAS subscales on moral values, conditional on political ideology and religiosity; Objective 4: Identify clusters of individuals with similar moral values, political attitudes, religiosity, and abortion attitudes using cluster analysis. These research questions are investigated with Bayesian statistical methods, including the liberty dimension of the MFQ in the cultural and national context of Germany A convenience sample of German participants recruited from social media. Participants are asked to complete an online survey using the moral foundations questionnaire (J. Graham et al., 2011) with dimensions care/harm, fairness/cheating, loyalty/betrayal, authority/subversion, and purity/degradation as well as the liberty/oppression dimension (Iyer et al., 2012), the Attitudes Towards Abortion Scale (Stets and Leik, 1993; Loftus and Molenbergh, 2022), religious beliefs and practices, self-placement on the political left/right spectrum as well as socio-demographic variables.

description: Most of the prior works on designing codebooks for limited feedback systems have not considered the presence of strong line-of-sight (LOS) channel component. This paper proposes the design of polar-cap codebook (PCC) for multipleinput single-output (MISO) limited feedback systems subject to Rician fading channels. The codewords of the designed PCC are adaptively constructed according to the instantaneous strength of the LOS channel component. Simulation results show that the codebook can significantly enhance the performance of transmit beamforming in terms of received signal-to-noise ratio (SNR).

description: Social Networking Sites (SNS) are one of the most important ways of communication. In particular, microblogging sites are being used as analysis avenues due to their peculiarities (promptness, short texts...). There are countless researches that use SNS in novel manners, but machine learning has focused mainly in classification performance rather than interpretability and/or other goodness metrics. Thus, state-of-the-art models are black boxes that should not be used to solve problems that may have a social impact. When the problem requires transparency, it is necessary to build interpretable pipelines. Although the classifier may be interpretable, resulting models are too complex to be considered comprehensible, making it impossible for humans to understand the actual decisions. This paper presents a feature selection mechanism that is able to improve comprehensibility by using less but more meaningful features while achieving good performance in microblogging contexts where interpretability is mandatory. Moreover, we present a ranking method to evaluate features in terms of statistical relevance and bias. We conducted exhaustive tests with five different datasets in order to evaluate classification performance, generalisation capacity and complexity of the model. Results show that our proposal is better and the most stable one in terms of accuracy, generalisation and comprehensibility.
