description: Deutschland, Frankreich, Schweden und Österreich - Unterschiedliche Länder in unterschiedlichen Regionen Europas. Eine der zentralen Fragen dieser Dissertation ist, wie die einzelnen Künstler der genannten Länder ihre Liedtexte mit der Musik verbinden. Der erste Blick offenbart im Vergleich von Texten und Musik der jungen Singer-Songwriter eine Vielzahl von Gemeinsamkeiten. Die folgende nähere Betrachtung arbeitet schwer erkennbare Unterschiede heraus. Texte und Musik werden anhand von Gedichtanalysen und mit Sonic Visualiser betrachtet und in Zusammenhang gebracht. Für eine Verbindung der einzelnen Merkmale finden Interviews mit einigen der Künstlern Verwendung. Für die Künstler selbst, spielt besonders die eigene Individualität eine große Rolle. Insgesamt wird in dieser Arbeit deutlich, dass noch einiges an Forschungspotenzial in diesem aktuellen Thema vorhanden ist.
description: Germany. France, Sweden and Austria, they represent different countries in different areas of europe. The central point of this dissertation is, how artists in these countries connect text and music to create their art. A first glance compares the choosen young artists and shows a multitude of mutualities. Later on, the finer details are analysed and thus hardly recognizable differences are exposed. For this, texts are analysed like a poem while the music is analysed via „Sonic Visualiser“ at last both are connected through the timing of the song. To get a better understanding of the artists intentions, some of them were intervied in context of their music. For them mostly their individuality is the main point that is to be transmitted. Summing up, it is shown that there is still a huge potential for further studies concerning this still actual topic.

description: We obtain an exact formula for the equilibrium free energy of a charged quantum particle moving in a harmonic potential in the presence of a uniform external magnetic field and linearly coupled to a heat bath of independent quantum harmonic oscillators through the momentum variables. We show that the free energy has a different expression than that for the coordinate-coordinate coupling between the particle and the heat-bath oscillators. For an illustrative heat-bath spectrum, we evaluate the free energy in the low-temperature limit, thereby showing that the entropy of the charged particle vanishes at zero temperature, in agreement with the third law of thermodynamics.

description: We verify that quadratic divergences stemming from gravitational corrections to QED which have been conjectured to lead to asymptotic freedom near Planck scale are arbitrary (regularization dependent) and compatible with zero. Moreover we explicitly show that such arbitrary term contributes to the beta function of QED in a gauge dependent way in the gravitational sector.
Allen-Cahn and Cahn-Hilliard-like equations for dissipative dynamics of saturated porous media

description: We consider a saturated porous medium in the regime of solid-fluid segregation under an applied pressure on the solid constituent. We prove that, depending on the dissipation mechanism, the dynamics is described either by a Cahn-Hilliard or by an Allen-Cahn-like equation. More precisely, when the dissipation is modeled via the Darcy law we find that, for small deformation of the solid and small variations of the fluid density, the evolution equation is very similar to the Cahn-Hilliard equation. On the other hand, when only the Stokes dissipation term is considered, we find that the evolution is governed by an Allen-Cahn-like equation. We use this theory to describe the formation of interfaces inside porous media. We consider a recently developed model proposed to study the solid-liquid segregation in consolidation and we are able to fully describe the formation of an interface between the fluid-rich and the fluid-poor phase.
The Ideological Shade of the Constitutional Order: Public Law and Political Economy in the Eurozone
Creators: name: Lokdam, Hjalte
Publisher: name: Zenodo
Year: 2021

description: This paper argues that the Economic and Monetary Union (EMU) created at Maastricht conformed to the neoliberal theory of interstate federalism in seeking to constitute structural conditions that circumscribed the effective exercise of activist public authority at both the Member State and European level. A response to a perceived ‘crisis of governability,’ it was designed to address the problem of excessive, and ineffective, governmental interventions in economic matters. By separating monetary and fiscal policy, the EMU ensured that no single public authority at the Member State or European level could control all the main levers of economic government. The Eurozone Crisis challenged this construct by emphasising the need for a coherent and effective exercise of public authority. The problem was thus no longer an excess of government but the absence of effective governmental authority for the EMU as a whole. Eurozone Crisis reforms introduced a greater scope for federal interventions in the domestic affairs of Member States and such reforms have elicited a new constitutional imaginary, expressed by European elites, that emphasises the need to generate ‘European sovereignty.’ This imaginary departs radically from the original EMU by foreseeing an omnicompetent European governmental apparatus that is able to intervene in, and control, economic developments across the Union in accordance with political objectives. The constitutional imaginary of the EMU can thus no longer meaningfully be called neoliberal. The early response to the COVID-19 Crisis, furthermore, highlights that the objectives pursued under the reformed EMU may depart from the set of policies traditionally associated with neoliberalism. What it should be called instead, however, remains unclear.

description: The use of bioacoustics as a tool for bat research is rapidly increasing worldwide. There is substantial evidence that environmental factors such as weather conditions or habitat structure can affect echolocation call structure in bats and thus compromise proper species identification. However, intraspecific differences in echolocation due to geographical variation are poorly understood, which poses a number of issues in terms of method standardization. We examined acoustic data for Pteronotus cf. rubiginosus from the Central Amazon and the Guiana Shield. We provide the first evidence of intraspecific geographic variation in bat echolocation in the Neotropics, with calls significantly differing in almost all standard acoustic parameters for the two lineages of this clade. We complement our bioacoustic data with molecular and morphological data for both species. Considerable overlap in trait values prevents reliable discrimination between the two sympatric Pteronotus based on morphological characters. On the other hand, significant divergence in the frequency of maximum energy suggests that bioacoustics can be used to readily separate both taxa despite extensive intraspecific variability in their echolocation across the Amazon. Given the relative lack of barriers preventing contact between bat populations from the Central Amazon and French Guiana, the documented acoustic variation needs to be further studied in geographically intermediate locations to understand the potential isolation processes that could be causing the described divergence in echolocation and to determine whether this variation is either discrete or continuous.

description: This paper presents a new tool to find the spatial configuration of a mechanical
system which comprises elastic fibres interacting both with each other and/or
with rigid bodies. The configuration is determined by means of the principle
of the minimum elastic potential energy of the system. Coulomb friction is
neglected at the contacts. The paper gives an overview on the optimal representation
of the rigid body shapes in the collison detection problem. In particular,
the paper presents an elastic fiber model and describes the rigid body representation
adopted. Both have been implemented in the tool. Finally an application
of the tool to the biomechanical field is presented which makes it possible to find
the spatial configuration of the human ligaments at the ankle joint complex.

description: Die Entwicklung von biokompatiblen Arzneistoffträgersystemen zur lokalen Therapie am Innenohr erfordert eine detaillierte Untersuchung um die pharmazeutische Sicherheit, insbesondere Qualität, Wirksamkeit und Unbedenklichkeit zu gewährleisten. Im Rahmen der vorliegenden Dissertation wurden zwei neuartige Depotformulierungen, Implantate zur intracochleären und Scheibchen zur runden Fenster Applikation, entwickelt und umfangreich charakterisiert. Neben der Untersuchung von physikochemischen Parametern und in vitro Freisetzungsstudien ist eine Implantation am Zielorgan unumgänglich, um Aussagen über die Handhabung, Applikation und Stabilität der potenziellen Depotformulierungen treffen zu können. Insbesondere Computertomographie der Cochlea mit implantierten intracochleären Depotformulierungen lieferten Aufschluss über eine Durchführbarkeit der Applikation.
description: The development of biocompatible drug delivery systems for local therapy on the inner ear requires a detailed investigation in order to guarantee pharmaceutical efficacy, safety, and quality. In the context of the present dissertation, two novel drug delivery systems, implants for intracochlear application and discs for round window application, were developed and extensively characterized. In addition to the investigation of physicochemical parameters and in vitro release studies, implantation on the target organ is essential in order to be able to make statements about the handling, application and stability of the potential drug delivery system. In particular, computed tomography of the cochlea with implanted intracochlear implants provided information about the feasibility of the application.

Analysis of the heavy quarkonium states $h_c$ and $h_b$ with QCD sum rules
Creators: name: Wang, Zhi-Gang
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article, we take the tensor currents $\bar{Q}(x)σ_{μν}Q(x)$ to interpolate the $P$-wave spin-singlet heavy quarkonium states $h_Q$, and study the masses and decay constants with the Borel sum rules and moments sum rules. The masses and decay constants from the Borel sum rules and moments sum rules are consistent with each other, the masses are also consistent with the experimental data. We can take the decay constants as basic input parameters and study other phenomenological quantities with the three-point correlation functions via the QCD sum rules. The heavy quarkonium states $h_Q$ couple potentially to the tensor currents $\bar{Q}(x)σ_{μν}Q(x)$, and have the quark structure $ε^{ijk}ξ^{\dagger}σ^kζ$ besides the quark structure $ik_2^i ξ^{\dagger}σ\cdot (\vec{k}_1-\vec{k}_2)ζ$. In calculations, we take into account the leading-order, next-to-leading-order perturbative contributions, and the gluon condensate, four-quark condensate contributions in the operator product expansion. The analytical expressions of the perturbative QCD spectral densities have applications in studying the two-body decays of a boson to two fermions with the vertexes $σ_{μν}γ_5$ and $σ_{μν}$.

description: In manufacturing industry there is growing interest in measures of process capability under multivariate setting. While there are many statistical packages to assess univariate capability, a current problem with the multivariate measures of capability is the shortage of user friendly software. In this paper a Visual Basic program has been developed to realize an Excel spreadsheet that may be used to compute two multivariate measures of capability. Our aim is to provide a useful tool for practitioners dealing with multivariate capability assessment problems. The features of the program include easy data entry and clear report format.

description: We construct a family of spectral triples for the Sierpinski Gasket $K$. For suitable values of the parameters, we determine the dimensional spectrum and recover the Hausdorff measure of $K$ in terms of the residue of the volume functional $a\to$ tr$(a\,|D|^{-s})$ at its abscissa of convergence $d_D$, which coincides with the Hausdorff dimension $d_H$ of the fractal. We determine the associated Connes' distance showing that it is bi-Lipschitz equivalent to the distance on $K$ induced by the Euclidean metric of the plane, and show that the pairing of the associated Fredholm module with (odd) $K$-theory is non-trivial. When the parameters belong to a suitable range, the abscissa of convergence $δ_D$ of the energy functional $a\to$ tr$(|D|^{-s/2}|[D,a]|^2\,|D|^{-s/2})$ takes the value $d_E=\frac{\log(12/5)}{\log 2}$, which we call energy dimension, and the corresponding residue gives the standard Dirichlet form on $K$.

$\ell_0$-penalized maximum likelihood for sparse directed acyclic graphs

description: We consider the problem of regularized maximum likelihood estimation for the structure and parameters of a high-dimensional, sparse directed acyclic graphical (DAG) model with Gaussian distribution, or equivalently, of a Gaussian structural equation model. We show that the $\ell_0$-penalized maximum likelihood estimator of a DAG has about the same number of edges as the minimal-edge I-MAP (a DAG with minimal number of edges representing the distribution), and that it converges in Frobenius norm. We allow the number of nodes p to be much larger than sample size n but assume a sparsity condition and that any representation of the true DAG has at least a fixed proportion of its nonzero edge weights above the noise level. Our results do not rely on the faithfulness assumption nor on the restrictive strong faithfulness condition which are required for methods based on conditional independence testing such as the PC-algorithm.

description: Searching for more efficient, cheaper, and eco-friendly alternatives is one of the most urgent tasks of solid-state physics but the total number of possible compositions and structures in the chemical space exceeds the capability of brute-force experimental or theoretical searches. In this cumulative thesis, we perform prototype-based high-throughput searches in the chemical space. We use density functional theory (DFT) calculations to optimize the structures and evaluate their thermodynamic stability according to distances to the convex hull. We first show that for one specific prototype, using intuition from domain knowledge could achieve successful outcomes. Then, we use a less-human-intervened strategy based on a data-mining similarities scale between elements. We find about 19k new stable compounds. Further, we use the trained machine learning models and systematically generate and calculated possible two-dimensional motifs, we filter out around 6.5k new 2D systems.
description: Die Suche nach effizienteren, billigeren und umweltfreundlicheren Alternativen ist eine der dringlichsten Aufgaben der Festkörperphysik, doch die Gesamtzahl der möglichen Zusammensetzungen und Strukturen im chemischen Raum übersteigt die Möglichkeiten der experimentellen oder theoretischen Brute-Force-Suche. In dieser Arbeit führen wir eine prototypbasierte Hochdurchsatzsuche durch. Wir verwenden DFT-Berechnungen, um die Strukturen zu optimieren und ihre thermodynamische Stabilität anhand der Abstände zur konvexen Hülle zu bewerten. Wir zeigen zunächst erfolgreiche Suchen für bestimmte Prototypen. Dann verwenden wir eine weniger von Menschenhand geprägte Strategie, die auf einer Ähnlichkeitsskala zwischen Elementen basiert. Wir finden etwa 19k neue stabile Verbindungen. Des Weiteren verwenden wir die trainierten ML-Modelle und generieren und berechnen systematisch mögliche zweidimensionale Motive, wobei wir etwa 6,5k neue 2D-Systeme herausfiltern.

description: In this study, 3,355 grade 9 and 10 students participated from 36 schools. The objective of this dissertation is to discuss the prevalence of tobacco, alcohol and khat among secondary school students in Ethiopia. A total of 2.4 % of students were regular users of cigarettes. Of the study participants, 17 % of students regularly used alcohol and 8.5 % used khat in lifetime. In this study, ever use of khat, ever use of alcohol, having a friend who smoked cigarette were associated with ever use of cigarettes. This study recommends that awareness-raising programs about the negative health effects of substance use should be designed for students. The school environment should be free from cigarettes and shisha by enforcing already existing tobacco control laws. Khat accessibility and consumption should be restricted for young. We believe that this study finding contributes to designing preventive strategies for substance use among secondary school students in Ethiopia.
description: In dit onderzoek nahmen 3.355 Schüler der Klassen 9 und 10 aus 36 Schulen teil. Das Ziel dieser Dissertation ist es, die Prävalenz von Tabak, Alkohol und Khat unter Sekundarschülern in Äthiopien zu diskutieren und Determinanten für den Konsum von Tabakprodukten zu identifizieren. Insgesamt 2,4 % der Studierenden konsumierten regelmäßig Zigaretten. Von den Studienteilnehmern konsumierten 17 % regelmäßig Alkohol und 8,5 % Khat. Faktoren, die mit dem Tabakkonsum in Verbindung gebracht werden sind der Konsum anderer Substanzen wie Khat und Alkohol sowie rauchende Freunde. Das Schulumfeld sollte frei von Zigaretten und Shisha sein, indem bestehende Tabakkontrollgesetze durchgesetzt werden und die Zugänglichkeit von Khat sollten für junge Heranwachsende eingeschränkt werden. Damit kann diese Studie einen Beitrag für den Entwurf präventiver Strategien für den Substanzkonsum bei Sekundarschülern leisten.
Ideologies and Imaginaries of Legitimacy from the 1950S to Today: Trajectories of EU-Official Discourses Read against Rosanvallon's Democratic Legitimacy
Creators: name: Sternberg, Claudia
Publisher: name: Zenodo
Year: 2021

description: This chapter traces changes in EU-official discourse around EU legitimacy since the 1950s, relating them to the trajectory described by Pierre Rosanvallon in Democratic Legitimacy (2011a). Accordingly, the legitimacy of modern democracies broke down in the 1980s owing to a loss of faith in its two main foundations in elections and bureaucracy. This gave rise to the emergence of alternative modes of legitimation, classed under the ideal types of impartiality, reflexivity, and proximity. This chapter plays Rosanvallon’s analysis, which draws on national experiences, against the EU context. It finds important differences, in particular regarding the balance between electoral and bureaucratic legitimacy in the earlier years of integration – as well as significant similarities and interaction, manifested in a striking resonance between particular strands in EU-official legitimation strategies and Rosanvallon’s ideal types. The ways in which they played out in the case of the EU point to dangers inherent to them; of highlighting proximity over actual influence and control; making democratic forms so complex and ‘reflexive’ that they become unintelligible, and unaccountable; or replicating bureaucratic thinking that obscures choices and judgments behind claims to independence and impartiality. What is more, the discursive history of contests over EU legitimacy illustrates a predisposition of Rosanvallon’s account of democratic legitimacy towards “unpolitical democracy”, rooted in its attempt to contain the threat of populism. His goal is to politicise the indirect institutions of impartiality, reflexivity and proximity rather than democratic procedures such as voting and majority rule, with the effect that deliberation is used strategically as an alternative to electoral and partisan democracy.

description: Die Zunge ist am häufigsten von intraoralen Krebs betroffen. Dies ist weltweit ein ernsthaftes Problem für die öffentlichen Gesundheit mit erheblicher Morbidität und Mortalität. In dieser Arbeit wurden 34, von Plattenepithelkarzinomen der Zunge stammende, Zelllinien verwendet und hohe SRC-Kinase-Aktivität wurde als potenzielles molekulares Ziel bei Zungenkrebs identifiziert. Der SRC-Kinase-Inhibitor Dasatinib zeigte in Kombination mit HSP90-Inhibitoren eine moderate synergistische Wirkung auf das Überleben von TSCC-Zellen. Noch vielversprechendere synergistische Wechselwirkungen wurden bei der Kombination von Dasatinib mit mehreren klinisch angewendeten Glukokortikoiden beobachtet. Beide Kombinationsbehandlungen (DAS+HSP90i und DAS+GC) zeigten eine Wirkung auf die Zellzyklusverteilung, induzierte Seneszenz und Autophagie, aber nicht auf die Apoptose. Es wurde festgestellt, dass GCs eine schnelle und anhaltende Hemmung der MET-Kinase-Phosphorylierung induzieren. GCs induzierten auch eine späte EGFR-Aktivierung, möglicherweise als kompensatorischer Überlebensmechanismus bei MET-Hemmung.
description: The tongue is the most common site for intraoral cancers. Worldwide, it is a serious public health problem with significant morbidity and mortality. This work utilized 34 tongue squamous cell carcinoma-derived cell lines and identified high levels of SRC kinase activity as a potential molecular target in tongue cancer. The SRC kinase-inhibitor Dasatinib was found to exhibit a moderate synergistic activity in combination with HSP90 inhibitors on the survival of TSCC cells. More promising synergistic interactions were seen upon the combination of Dasatinib with several clinically applied Glucocorticoids. Both combination treatments (DAS+HSP90i and DAS+GC) showed an effect on cell cycle distribution, induced senescence and autophagy but not on apoptosis. GCs were found to induce rapid and prolonged inhibition of MET kinase phosphorylation. GCs also induced late EGFR activation, possibly as a compensatory survival mechanism upon MET inhibition.

description: The aim of this work was to study the growth and nutrient removal efficiency of a mixed microalgal culture with and without the addition of low concentrations (0.5, 1, and 5 g L-1 of total liquid volume in the reactor) of natural zeolite. A control test in which only zeolite was added into a similar membrane photobioreactor was also conducted. The addition of 0.5 g L-1 zeolite to a continuously-fed membrane photobioreactor increased the microalgal biomass concentration from 0.50 to 0.90–1.17 g particulate organic carbon per L while the average ammonium removal efficiency increased from 14% to 30%. Upon microscopic inspection, microalgal cells were observed growing on the surface of zeolite particles, which indicates that zeolite can support attached microalgal growth. With higher zeolite doses (1 and 5 g L-1) inside the reactor, however, the breaking apart of added zeolite particles into finer particles dramatically increased solution turbidity, which likely was not beneficial for microalgal growth and ammonium removal due to reduced light penetration. This work shows that low doses of zeolite can be used as microcarriers to enhance microalgal biomass concentration and ammonium removal efficiency, while minimizing zeolite dose would likely reduce the turbidity effects.

description: After decades of oblivion the status of Lois Weber’s production has emerged as one of the most important in American cinema of the 1910s. Indeed, recent historical research has made clear that by 1915 Weber had become a popular celebrity whose work was as distinctive as that of Griffith and De Mille. In her most famous and successful films, Weber tackled some of the controversial issues of the period which she treated in a moral fashion. Where Are My Children? (1916) is the first of four films dealing with birth control while Shoes (1916), for example, deals with underpaid female labor. In both cases, as in other films, Weber’s social discourse develops along a dual axes, that of gender and class. Though she didn’t consider herself strictly a feminist, she thought of her work in line with that of activists and reformers, including feminists such as Margaret Sanger and Jane Addams. It is interesting to note that well before current debates around essentialism and anti-essentialism, Weber was well aware, like many feminists of the time, that women’s condition as gendered subjects was not unique and universal, but intimately related to their class.
Progress towards the synthesis of the bacterial menaquinone biosynthetic enzyme, 1,4-dihydroxy-6-naphthoate synthase
Creators: name: Hrysio, Ursula Winter
Publisher: name: University of British Columbia
Year: 2014

description: 1,4-dihydroxy-6-naphthoate (DHN) synthase is one of several enzymes of the menaquinone biosynthetic pathway found in pathogenic bacteria including Campylobacter jejuni and Helicobacter pylori. It is responsible for catalyzing the formation of the 1,4-dihydroxy-6-naphthoate core of the electron transport system cofactor, menaquinone. Since humans lack the ability to synthesize menaquinone, enzymes of bacterial menaquinone biosynthesis have been targeted for inhibitor design. In order to aid the design of potential inhibitors of DHN synthase, its mechanism of catalysis has to be conclusively proven. We have proposed two possible reaction mechanisms that can be distinguished from one another, as they release different 3-carbon byproducts in addition to DHN. In order to establish the identity of these byproducts, and thus establish DHN synthase’s mechanism of action, hundred milligram quantities of substrate, much higher than the natural quantity of enzymatically-produced substrate, have to be synthesized. Accesss to synthetic substrate will allow for kinetic testing of potential inhibitors. In this thesis, progress towards the synthesis of two compounds will be presented. One is the natural substrate, CDHF, cyclic de-hypoxanthine futalosine and the other, de-carboxy CDHF, is a substrate analog devoid of a carboxylic acid functionality. We have demonstrated that an oxidative aromatic cyclization of a naphthol core successfully produces a key intermediate in the overall synthesis. This should ultimately allow for the completion of the synthesis of the substrate and the elucidation of the mechanism.

description: Trotz der Entwicklung neuer Therapiekonzepte haben Patienten mit nicht-kleinzelligem Bronchialkarzinom (NSCLC) eine sehr schlechte Prognose. Zirkulierende mikro-RNA (miRNA) sind potenzielle Biomarker mit prognostischer und prädiktiver Bedeutung in Krebspatienten. Es wurde die Konzentration der miR-16, miR-29a, miR-144 und miR-150 im Plasma von Patienten mit NSCLC zu verschiedenen Zeitpunkten einer Radiotherapie untersucht. Die medianen Expressionslevel der vier miRNA unterschieden sich deutlich und die miR-29a und miR-150 zeigten einen Abfall während der Radiotherapie. Die Level der miR-29a und miR-144 zeigten einen prognostischen Wert während und nach Bestrahlung. Patienten mit niedrigen Expressionsleveln wiesen eine schlechtere Prognose auf. Eine kombinierte Variable aus vier miRNA zeigte einen unabhängigen prognostischen Wert nach Bestrahlung. Zusammenfassend zeigte sich nach Bestrahlung eine prognostische Bedeutung der miRNA in Patienten mit NSCLC.
description: Despite the success of current therapy concepts, patients with non-small-cell lung cancer (NSCLC) still have a very poor prognosis. Circulating microRNAs (miRs) have potential as biomarkers for prognosis and prediction of response to therapy in cancer patients. The concentration of miR-16, miR-29a, miR-144 and miR-150 was assessed in plasma of NSCLC patients at different time points of radiotherapy by droplet digital PCR. Their impact on patients’ prognosis was evaluated. The mean plasma levels of miR-16, miR-29a, miR-144 and miR-150 differed interindividually and miR-29a and miR-150 showed a decrease of expression during radiotherapy. The plasma levels of miR-29a and miR-144 had prognostic value in NSCLC patients during or at the end of radiotherapy. NSCLC patients with low levels of these miRs had a worse prognosis. A combined variable of four miRNAs showed independent prognostic value. In conclusion, circulating miRs have a prognostic value in NSCLC patients undergoing radiotherapy.

description: The essay deals with the problem of women workers employed as hand colorists in Italy between the end of the nineteenth and the beginning of the twentieth century. It explores general issues such as the relation between the modern development of industrial coloring processes and the professions involved, the continuity between the coloring techniques in the film industry and those employed in other production fields (e.g. photography). The text subsequently investigates the situation of women workers and the gendered forms of labor division in the Roman laboratories of Cines between 1905 and 1910.

description: We study the possibility of taking bosonic systems subject to quadratic Hamiltonians and a noisy thermal environment to non-classical stationary states by feedback loops based on weak measurements and conditioned linear driving. We derive general analytical upper bounds for the single mode squeezing and multimode entanglement at steady state, depending only on the Hamiltonian parameters and on the number of thermal excitations of the bath. Our findings show that, rather surprisingly, larger number of thermal excitations in the bath allow for larger steady-state squeezing and entanglement if the efficiency of the optimal continuous measurements conditioning the feedback loop is high enough. We also consider the performance of feedback strategies based on homodyne detection and show that, at variance with the optimal measurements, it degrades with increasing temperature.

Navigating water access and governance in peri-urban Ashaiman, Ghana : a case study
Creators: name: Peloso, Megan Michelle
Publisher: name: University of British Columbia
Year: 2014

description: Low-income, peri-urban residents of Greater Accra face disparities in water access, particularly given that piped water services provided by the formal municipal network are highly erratic and unreliable. Often, those underserved by the official provider are able to meet their daily water needs by sourcing water through alternative, or informal, means. Although it is often the case that informal water services pose important challenges for users, for instance in terms of price and quality, this research attempts to understand other dimensions of how populations are served when they are not adequately reached by formal networks. This research also explores the potential for participatory water governance, querying policy and scholarly literatures that advocate for a more inclusive water governance process on the grounds that it is key towards service extension and empowerment. This thesis is based on two months of fieldwork in Ashaiman, a rapidly growing settlement located on the outskirts of the capital region of Accra, Ghana. The overall objective of the thesis is twofold: (1) To examine the myriad of mediums and networks through which water is accessed, with particular attention to those that extend beyond the municipal water system, and (2) To assess how participation in water governance is experienced and expressed by the peri-urban poor, with the aim of considering possibilities for managing water concerns in this context. These themes are addressed respectively in the two substantive chapters of this thesis. Insights suggest that a diversity of strategies to obtain water is a key factor in allowing peri-urban dwellers to cope with water insecurities. In addition, mainstream approaches to participatory water governance may be at odds with local institutions operating within Ashaiman, which tend to be multi-purpose and adaptive, based on a wide-ranging goal of improving social welfare. Among other implications of these findings, it is concluded that an in-depth process of consultation with community members, organizations and private water vendors is imperative to promote collaborative governance of water and well-being, where members themselves define the scope of the mandate, and where the critical role of informal water networks is accounted for.
Application of three-body stability to globular clusters: I. The stability radius

description: The tidal radius is commonly determined analytically by equating the tidal field of the galaxy to the gravitational potential of the cluster. Stars crossing this radius can move from orbiting the cluster centre to independently orbiting the galaxy. In this paper, the stability radius of a globular cluster is estimated using a novel approach from the theoretical standpoint of the general three-body problem. This is achieved by an analytical formula for the transition radius between stable and unstable orbits in a globular cluster. A stability analysis, outlined by Mardling, is used here to predict the occurrence of unstable stellar orbits in the outermost region of a globular cluster in a distant orbit around a galaxy. It is found that the eccentricity of the cluster-galaxy orbit has a far more significant effect on the stability radius of globular clusters than previous theoretical results of the tidal radius have found. A simple analytical formula is given for determining the transition between stable and unstable orbits, which is analogous to the tidal radius for a globular cluster. The stability radius estimate is interior to tidal radius estimates and gives the innermost region from which stars can random walk to their eventual escape from the cluster. The time-scale for this random walk process is also estimated using numerical three-body scattering experiments.

description: We consider the inverse problem of reconstructing an effective model for a prototypical diffusion process in strongly heterogeneous media based on low-resolution measurements. We rely on recent quasi-local numerical effective models that, in contrast to conventional homogenized models, are provably reliable beyond periodicity assumptions and scale separation. The goal of this work is to show that the identification of the matrix representation of these effective models is possible. Algorithmic aspects of the inversion procedure and its performance are illustrated in a series of numerical experiments.
Informal Employment in Russia: Incidence, Determinants and Labor Market Segmentation

description: This paper takes stock of informal employment in Russia analyzing its incidence and determinants. Using the regular waves and an informality supplement of the Russian Longitudinal Monitoring Survey (RLMS) it develops several measures of informal employment and demonstrates that the incidence varies widely across the different definitions. We also show that the determinants of informal employment are roughly stable across the different measures: workers who are males, relatively young, unskilled and employed in construction and trade and related services have a higher likelihood to have an informal job. We also take a look at the issue of labor market segmentation along the informal-formal divide by estimating an informal-formal wage gap at the means and across the entire wage distributions. We find only weak evidence for labor market segmentation in Russia when estimating an informal-formal wage gap for salaried workers at the mean. The results of quantile regressions show a wage penalty in the lower half of the distribution and no gap in the upper half for informal employees. In contrast, informal self-employed and entrepreneurs have conditional mean wages that are higher than the mean wages for the formally employed. Across the entire wage distribution, however, we find a negative wage gap in the lowest quartile and a strongly positive wage gap in the highest quartile, pointing to a segmented informal sector with a lower free entry tier and an upper rationed tier.

An Alliance Between History and Theory

description: The rediscovery of the early cinema in the 1980s brought about a change in film historiography that the women’s movement had in essence already proposed in the 1970s. At the time, at issue here were not only women directors, forgotten by film historiography, but also the varied and primarily anonymous group of women working in the realms that classical film history did not register: those working in film laboratories, in film coloring, as film editors, on the screenplay and (not least) as actresses, something that is not identical with the function of stars, shaped by men. Using the figure of the actress (and Asta Nielsen in particular) and concentrating on the cinema of the seconde époque, this paper explores women’s liberation from male domination. It argues that the actress places the reality of perceptual play in a public space. Thanks to her, a form of communal life that the women formed in and with the home is freed from the walls of the private.
Mandatory Reporting and Adolescent Sexual Assault

description: Adolescents experience alarmingly high rates of sexual violence, higher than any other age-group. This is concerning as sexual violence can have detrimental effects on teens’ personal and relational well-being, causing long-term consequences for the survivor. Still, adolescents are hesitant to report the assault or seek out services and resources. When an adolescent survivor does seek out services, they may interact with a provider who is a mandatory reporter. This scoping review sought to synthesize the current U.S.-based research on the role, challenges, and impact of mandatory reporting (MR) in the context of adolescent sexual assault. Database searches using key words related to MR, sexual assault, and adolescence identified 29 peer-reviewed articles. However, none of these articles reported on empirical investigations of the phenomenon of interest and instead consisted of case studies, commentaries, and position papers. The scoping review was expanded to provide a lay of the land of what we know about the intersection of adolescent sexual assault and MR. Results of the review indicate that though implemented broadly, MR policies vary between individuals, organizations, and states and have historically been challenging to implement due to this variation, conflicts with other laws, tension between these policies and providers’ values, and other factors. Based on the available literature, the impact of MR in the context of adolescent sexual assault is unknown. There is a critical need for research and evaluation on the implementation and impact of MR policies, especially in the context of adolescents and sexual violence.
