reputation management

description: Reputation management is not straightforward and is an ongoing and active process. This paper considers the unique challenges to reputation management for regulatory agencies by considering five problems: politics, consistency, charisma, uniqueness, and excellence. This research advances the existing literature to consider how a regulatory agency can mitigate these problems in order to develop reputation management strategies with government decision-makers. Carpenter’s regulatory agency reputation management theory, the foundation of this research, emphasizes the fundamental importance of the legitimacy for regulators and categorizes regulatory reputation into four dimensions: performative, moral, technical, and legal procedural. Through a constructivist/interpretive paradigm viewpoint, data was gathered through six semi-structured interviews with current and former non-elected government Alberta Department of Energy civil servants. The Alberta Utilities Commission is referenced throughout the paper as an example that illustrates the unique challenges and how Carpenter’s theory can provide a strategic lens for regulators engaged in reputation management focused on government relations. The findings reveal that there is a fundamental importance that a regulator maintain legitimacy through a clear vision of its raison d’être. In addition, communication should be regular, proactive, transparent, and constructive to build relationships with people in all levels of government including elected officials that emphasizes how the agency is achieving policy outcomes. The results of this study contribute to the small body of literature that considers how regulatory agencies seek to establish a public image and communicate that image to influence government decision-makers without negatively affecting the independent and adjudicative function of quasi-judicial regulators.

description: Die Europawahl 2019 hat in Deutschland markante regionale Unterschiede im Wahlverhalten aufgezeigt. Im Vergleich zur Bundestagswahl verzeichnen vor allem die Grünen starke Stimmengewinne in westdeutschen Kreisen, während die AfD ihren Erfolg in den ostdeutschen Kreisen konsolidieren kann. Dieser Wochenbericht untersucht auf Kreisebene, welche strukturellen Faktoren das Abschneiden der beiden Parteien bei der Europawahl erklären. Der Zuspruch für die Grünen ist in wirtschaftlich starken, demografisch jungen und dynamischen sowie wirtschaftsstrukturell soliden Kreisen hoch. Dagegen schneidet die AfD in Kreisen gut ab, die wirtschaftlich schwächer und verwundbarer sind und unter Abwanderung leiden. Die Stärke sowohl von Grünen als auch AfD ist dabei weniger durch aktuelle wirtschaftliche Entwicklungen, sondern mehr durch strukturelle und demografische Faktoren geprägt. Grüne und AfD stellen somit nicht nur auf der politischen Bühne Gegenpole dar, ihre Ergebnisse bei der Europawahl spiegeln auch die gesellschaftliche Spaltung Deutschlands auf regionaler Ebene wider.

Subjects: CAO

Municipal Council

description: This study attempted to understand the critical relationship between the Chief Administrative Officer (CAO) and municipal council, and further how it affects stakeholders. A review was made of the literature on local government in general, CAOs, and leadership. Qualitative research, and specifically exploring personal experience, was the best approach to understand the nature of this alliance. This research adheres to the Royal Roads University Research Ethics Policy. A broad Canada wide survey was used (866 responses), followed by narrative interviews (five CAOs and five politicians) to generate the data. The responses confirmed that the CAO/council relationship was indeed a critical one, further, that the largest contributor to the downfall of this relationship was role clarity. Through the research a systems model was developed to demonstrate the interactions between cause and effect.

description: We present results of our Monte Carlo simulation of the Ising-O(3) model on the two-dimensional (2D) and quasi-2D lattices. This model is an effective classical model for the stacked square-lattice $J_1$-$J_2$ Heisenberg model where the nearest neighbor ($J_1$) and next-nearest neighbor ($J_2$) couplings are frustrated and we assume that $J_2$ is dominant. We find an Ising ordered phase where the O(3) spins remain disordered in a moderate quasi-2D region. There is a single first order transition for a sufficiently large 3D coupling. Our results can provide a qualitative explanation on the experiments on ferropnictides, namely observed sequence and orders of the structural and magnetic transitions, in terms of the ratio between the inter-layer and intra-layer coupling.

description: The second-order gravitational self-force on a small body is an important problem for gravitational-wave astronomy of extreme mass-ratio inspirals. We give a first-principles derivation of a prescription for computing the first and second perturbed metric and motion of a small body moving through a vacuum background spacetime. The procedure involves solving for a "regular field" with a specified (sufficiently smooth) "effective source", and may be applied in any gauge that produces a sufficiently smooth regular field.

description: Die Arbeitsproduktivität hat in der Bundesrepublik gesamtwirtschaftlich über die Jahrzehnte immer langsamer zugelegt; zuletzt hat sie nur noch stagniert. Das steht in Kontrast zum steigenden Qualifikationsniveau der Arbeitskräfte infolge einer rasanten Akademisierung. Beides sind Phänomene, die auch in anderen entwickelten Ländern zu beobachten sind. Mitunter wird als Ursache auf den sektoralen Wandel verwiesen. Tatsächlich hat die Verschiebung der Wirtschaftsaktivitäten hin zu den Dienstleistungen die Produktivitätsentwicklung seit der Jahrtausendwende gehemmt; groß war der Bremseffekt aber nicht. Anknüpfend an eine Debatte etwa in den USA wird in diesem Bericht der Blick auf Bürokratisierungstendenzen gerichtet. So zeigt eine Auswertung der Daten des Mikrozensus, dass Jobs, die zum Kernbereich von Bürokratien zu zählen sind, in Deutschland an Bedeutung gewonnen haben. Dies könnte ein Grund für das geringe Produktivitätswachstum sein. Ob dieser Zusammenhang tatsächlich empirisch belegbar ist und inwieweit diese Entwicklung zur Abschwächung des Produktivitätsanstiegs beigetragen hat, muss durch weitere Forschung geklärt werden.

Insbesondere der weitreichende Umbau der Energiewirtschaft erfordert neue Technologien, innovative Geschäftsmodelle und digitale Lösungen. Der vorliegende Bericht untersucht die Innovationsdynamik der Branche über die letzten Jahre. Die Befunde zeigen, dass Unternehmen der deutschen Energie-, Wasser- und Entsorgungswirtschaft in den vergangenen Jahren nur wenig in eigene Forschung und Entwicklung investiert haben. Hingegen investierten die Unternehmen verstärkt in innovative Technologien, die in anderen Sektoren, etwa dem Maschinenbau, entwickelt wurden. Dies betrifft vor allem die Bereiche Klimaschutz und Digitalisierung. Um die künftigen Herausforderungen zur Erfüllung der Klimaschutzziele effektiv zu meistern, sollten die politischen Rahmenbedingungen so ausgestaltet werden, dass innovative Technologien verstärkt erforscht werden und zum Einsatz kommen können.

description: In this paper we consider a perturbation of the Ricci solitons equation proposed by J. P. Bourguignon in \cite{jpb1}. We show that these structures are more rigid then standard Ricci solitons. In particular, we prove that there is only one complete three--dimensional, positively curved, Riemannian manifold satisfying $$ Ric -\frac{1}{2} R \, g \, + \, \nabla^2 f \, = \,0\,, $$ for some smooth function $f$. This solution is rotationally symmetric and asymptotically cylindrical and it represents the analogue of the Hamilton's cigar in dimension three. The key ingredient in the proof is the rectifiability of the potential function $f$. It turns out that this property holds also in the Lorentzian setting and for a more general class of structures which includes some gravitational theories.

Understanding China’s attitude toward international order : from general delegitimization to selective embeddedness
Creators: name: Zhang, Chunman
Publisher: name: University of British Columbia
Year: 2013

description: China is rising and playing an increasing important role in both regional and international affairs. As for China’s attitude toward international order, this thesis argues that since 1992 China has been gradually shifting its attitude towards international order from general delegitimization to selective embeddedness by using political discourse analysis and fuzzy-set analysis methods. Why has China become less critical of the international order in the past few years but in 1990s China severely criticized it? In terms of the relationship between China and the West, why does China cooperate with the West in some areas while fighting with it in others? This paper proposes an identity-attitude model to explain these puzzles. It argues that China’s attitudinal change is caused by the change of China’s identity. China cooperates with the West only when China perceives itself as the beneficiary of the international order.

description: We present details of a lattice study of infrared behaviour in SU(3) gauge theory with twelve massless fermions in the fundamental representation. Using the step-scaling method, we compute the coupling constant in this theory over a large range of scale. The renormalisation scheme in this work is defined by the ratio of Polyakov loops in the directions with different boundary conditions. We closely examine systematic effects, and find that they are dominated by errors arising from the continuum extrapolation. Our investigation suggests that SU(3) gauge theory with twelve flavours contains an infrared fixed point.

description: In models where lepton number is considered to be a spontaneously-broken global symmetry a massless Goldstone boson, the majoron (J), appears. We describe a procedure to explore the muon-electron-majoron coupling using the results from mu-e conversion search experiments. To accomplish that, we determine how the energy spectrum of the muon decay into an electron and a majoron is modified by binding effects in a muonic atom. We find that the future mu-to-e conversion experiments may be able to produce bounds on the mu->eJ rate which are comparable with the present ones from direct searches.

description: We develop two approaches for analyzing the approximation error bound for the Nyström method, one based on the concentration inequality of integral operator, and one based on the compressive sensing theory. We show that the approximation error, measured in the spectral norm, can be improved from $O(N/\sqrt{m})$ to $O(N/m^{1 - ρ})$ in the case of large eigengap, where $N$ is the total number of data points, $m$ is the number of sampled data points, and $ρ\in (0, 1/2)$ is a positive constant that characterizes the eigengap. When the eigenvalues of the kernel matrix follow a $p$-power law, our analysis based on compressive sensing theory further improves the bound to $O(N/m^{p - 1})$ under an incoherence assumption, which explains why the Nyström method works well for kernel matrix with skewed eigenvalues. We present a kernel classification approach based on the Nyström method and derive its generalization performance using the improved bound. We show that when the eigenvalues of kernel matrix follow a $p$-power law, we can reduce the number of support vectors to $N^{2p/(p^2 - 1)}$, a number less than $N$ when $p > 1+\sqrt{2}$, without seriously sacrificing its generalization performance.

description: We propose a new single-step scheme for the generation of a GHZ entangled state of three single-electron excitations (flying qubits). We also present a method to get a generalized GHZ-state. Our idea relies upon the most recent progress in the field of on-demand electron sources and mesoscopic Mach-Zehnder interferometry. We also provide the recipe for the unambiguous detection of this GHZ state via correlations measurements at the output, which imply the violation of a Bell-type inequality which is generalized to the case of three particles. We explain how such measurements can be achieved in the context of Mach-Zehnder interferometry, and draw an actual prototype device which could be achieved with point contacts and metallic gates placed on a GaAs sample, in the integer quantum Hall effect regime.

description: Die Preise für Immobilien sind in vielen Ländern in den vergangenen Jahren deutlich gestiegen und es wächst die Sorge, dass sich erneut spekulative Preisblasen bilden. Für politische Entscheidungsträger kann es dabei schwer sein, den richtigen Zeitpunkt für regulierende Eingriffe in den Markt zu erkennen. In diesem Bericht wird gezeigt, wie moderne Methoden des maschinellen Lernens genutzt werden können, um spekulative Preisübertreibungen frühzeitig vorherzusagen. So zeigen die Prognosemodelle, dass die Risiken in vielen OECD-Ländern wieder sehr hoch sind. In Deutschland ist eine explosive Preisentwicklung festzustellen, die sich von den Erträgen von Immobilien entkoppelt hat. Allerdings weist das Prognosemodell darauf hin, dass sich das Risiko in den kommenden Monaten auf hohem Niveau etwas reduzieren wird. Leider ist das Instrumentarium prophylaktischer Maßnahmen in Deutschland noch nicht ausreichend. So fehlt es beispielsweise an Eingriffsmöglichkeiten, die auf die Verschuldungsobergrenzen von Haushalten abstellen. Auch ist unklar, ab wann die Bundesanstalt für Finanzdienstleistungsaufsicht (BaFin) in den Markt eingreifen kann.

description: A broad class of scenarios for new physics involving additional strongly-interacting fields generically predicts signatures at hadron colliders which consist solely of large numbers of jets and substantial missing transverse energy. In this work, we investigate the prospects for discovery in such scenarios using a search strategy in which jet multiplicity and missing transverse energy are employed as the primary criteria for distinguishing signal from background. We examine the discovery reach this strategy affords in an example theory (a simplified supersymmetric model whose low-energy spectrum consists of a gluino, a light stop, and a light neutralino) and demonstrate that it frequently exceeds the reach obtained via other, alternative strategies.

description: Die Investitionen im Euroraum sind auch zehn Jahre nach der Finanzkrise noch immer nicht auf dem Vorkrisenniveau. Öffentliche und private Investitionen entwickeln sich so schwach, dass der Kapitaleinsatz pro Erwerbstätigem nahezu konstant bleibt. Ein Anstieg der öffentlichen Investitionstätigkeit könnte auch die private anregen. Schätzergebnisse für den Euroraum zeigen, dass ein Anstieg öffentlicher Investitionen um eine Milliarde Euro mit einem mittelfristigen Anstieg der privaten Investitionen von etwa 1,1 Milliarden Euro einhergeht. In Deutschland ist der Effekt sogar etwas größer: Eine investierte öffentliche Milliarde Euro erhöht die privaten Investitionen im Zeitraum von fünf Jahren um knapp zwei Milliarden Euro. Der Effekt wird insbesondere durch Bau- und Infrastrukturinvestitionen getrieben. Die weitreichende Investitionszurückhaltung der öffentlichen Hand könnte somit auch einen Teil der Schwäche der privaten Investitionstätigkeit erklären. Öffentliche Investitionen müssen jetzt verstärkt getätigt werden. Dazu sollte die starre Schuldenbremse von flexibleren Ausgabenregeln abgelöst werden.

description: Current observations suggest that the universe was reionized sometime before z~6. One way to observe this epoch of the universe is through the Near Infrared Background (NIRB), which contains information about galaxies which may be too faint to be observed individually. We calculate the angular power spectrum (C_l) of the NIRB fluctuations caused by the distribution of these galaxies. Assuming a complete subtraction of any post-reionization component, C_l will be dominated by galaxies responsible for completing reionization (e.g., z~6). The shape of C_l at high l is sensitive to the amount of non-linear bias of dark matter halos hosting galaxies. As the non-linear bias depends on the mass of these halos, we can use the shape of C_l to infer typical masses of dark matter halos responsible for completing reionization. We extend our previous study by using a higher-resolution N-body simulation, which can resolve halos down to 10^8 M_sun. We also include improved radiative transfer, which allows for the suppression of star formation in small-mass halos due to photo-ionization heating. As the non-linear bias enhances the dark-matter-halo power spectrum on small scales, we find that C_l is steeper for the case with a complete suppression of small sources or partial suppression of star formation in small halos (the minimum galaxy mass is M_min=10^9 M_sun in ionized regions and M_min=10^8 M_sun in neutral regions) than the case in which these small halos were unsuppressed. In all cases, we do not see a turn-over toward high l in the shape of l^2 C_l.

description: The spectral theory of graphs provides a bridge between classical signal processing and the nascent field of graph signal processing. In this paper, a spectral graph analogy to Heisenberg's celebrated uncertainty principle is developed. Just as the classical result provides a tradeoff between signal localization in time and frequency, this result provides a fundamental tradeoff between a signal's localization on a graph and in its spectral domain. Using the eigenvectors of the graph Laplacian as a surrogate Fourier basis, quantitative definitions of graph and spectral "spreads" are given, and a complete characterization of the feasibility region of these two quantities is developed. In particular, the lower boundary of the region, referred to as the uncertainty curve, is shown to be achieved by eigenvectors associated with the smallest eigenvalues of an affine family of matrices. The convexity of the uncertainty curve allows it to be found to within $\varepsilon$ by a fast approximation algorithm requiring $O(\varepsilon^{-1/2})$ typically sparse eigenvalue evaluations. Closed-form expressions for the uncertainty curves for some special classes of graphs are derived, and an accurate analytical approximation for the expected uncertainty curve of Erdős-Rényi random graphs is developed. These theoretical results are validated by numerical experiments, which also reveal an intriguing connection between diffusion processes on graphs and the uncertainty bounds.

After a brief account of its basic concept and historical development, the paper is devoted to the theoretical formulations of RPA, and its applications to realistic systems. With several illustrating applications, we discuss the implications of RPA for computational chemistry and materials science. The computational cost of RPA is also addressed which is critical for its widespread use in future applications. In addition, current correction schemes going beyond RPA and directions of further development will be discussed.

description: Die Leistungsfähigkeit der deutschen Wirtschaft beruht auf ihren wissensintensiven Industrie- und Dienstleistungsunternehmen. Dennoch ist der Einsatz von Wissenskapital als wichtiger Treiber von Innovationen und Produktivität in Deutschland im Vergleich zu anderen europäischen Ländern und den USA mittlerweile eher gering. Deutlich zurück liegt das Land vor allem im Dienstleistungssektor. Aber selbst in der Industrie weisen die deutschen Unternehmen keinen überdurchschnittlichen Einsatz von Wissenskapital auf. Gleichzeitig ist der Modernitätsgrad des Wissenskapitals in Deutschlands Industrie- und Dienstleistungssektor gering. Dies gefährdet die Wettbewerbsfähigkeit der deutschen Wirtschaft. Die Bundesregierung hat eine Zielmarke zur Steigerung der FuE-Aufwendungen bis 2025 auf 3,5 Prozent des Bruttoinlandsprodukts ausgegeben. Bezogen auf die Unternehmensinvestitionen in das gesamte Wissenskapital entspricht dies einer fast 35 Milliarden Euro höheren jährlichen Investitionssumme. Diese zu erreichen, erfordert eine Überprüfung und Verbesserung der Rahmenbedingungen für Investitionen in Wissenskapital.

Holographic Renormalization for z=2 Lifshitz Space-Times from AdS

description: Lifshitz space-times with critical exponent z=2 can be obtained by dimensional reduction of Schroedinger space-times with critical exponent z=0. The latter space-times are asymptotically AdS solutions of AdS gravity coupled to an axion-dilaton system and can be uplifted to solutions of type IIB supergravity. This basic observation is used to perform holographic renormalization for 4-dimensional asymptotically z=2 locally Lifshitz space-times by Scherk-Schwarz dimensional reduction of the corresponding problem of holographic renormalization for 5-dimensional asymptotically locally AdS space-times coupled to an axion-dilaton system. We can thus define and characterize a 4-dimensional asymptotically locally z=2 Lifshitz space-time in terms of 5-dimensional AdS boundary data. In this setup the 4-dimensional structure of the Fefferman-Graham expansion and the structure of the counterterm action, including the scale anomaly, will be discussed. We find that for asymptotically locally z=2 Lifshitz space-times obtained in this way there are two anomalies each with their own associated nonzero central charge. Both anomalies follow from the Scherk--Schwarz dimensional reduction of the 5-dimensional conformal anomaly of AdS gravity coupled to an axion-dilaton system. Together they make up an action that is of the Horava-Lifshitz type with nonzero potential term for z=2 conformal gravity.

Twisted energy ladder : complexities and unintended consequences in the transition to modern energy services
Creators: name: Kowsari, Reza
Publisher: name: University of British Columbia

description: More than one-third of the world’s population has inadequate access to modern energy services and suffers as a consequence. A better understanding of energy transition is vital for improving future programs. This thesis investigates the challenges of transitioning to modern energy services with the goal of informing policy-making. Chapter 2 is a review of the literature on energy analysis and energy system uptake by the households with a particular focus on rural regions. Building upon the findings in the literature, a new conceptual framework is developed that can act as a basis for developing new empirical and theoretical models of household energy system uptake and use. In Chapter 3, the private sector based approach to rural energy provision (i.e. electrification and Improved Cookstove (ICS) dissemination) is investigated by examining two enterprises in India. Results indicate that the private sector based approach to rural energy provision cannot be a universal solution. It further shows that enterprises are facing many challenges that are beyond their capacity to address, necessitating alternate approaches to private sector involvement. Chapter 4 and 5 investigate the uptake of ICS by commercial kitchens in Bangalore and its potential health implications. The attributes of ICS and Liquefied Petroleum Gas (LPG) stove, as perceived by stove users and owners, are explored and the reasons for purchasing ICS are assessed. Results indicate that both groups mostly prefer LPG stoves and that ICS uptake is mainly motivated by economic factors. The potential health implications of this switch in the commercial kitchens are explored by investigating the stove’s emission characteristics (based on both secondary data and direct emission measurements), the stoves smokiness (as perceived by users and owners); and some health symptoms associated with stove smoke. Uptake of ICS by these commercial kitchens is found to potentially have adverse health implications. In brief, this thesis concludes that rural energy provision policies can be improved through a greater emphasis on the human dimension, comprehensive assessment of the target population, and ongoing evaluation of the programs’ outcomes given the major challenges in improving rural energy access and possibilities for spillovers into other market segments.

description: In der sich verschärfenden Diskussionen über wirksamen Klimaschutz wird sowohl in Deutschland als auch in Europa und weltweit die Atomkraft als „saubere Energie“ ins Spiel gebracht. Vor diesem Hintergrund analysiert dieser Bericht ihre historischen, gegenwärtigen und zukünftigen Kosten und Risiken. Die Ergebnisse zeigen, dass Atomkraft aufgrund radioaktiver Strahlung für über eine Millionen Jahre mitnichten als „sauber“ bezeichnet werden kann, sondern für Mensch und Umwelt gefährlich ist. Zudem fallen hohe Risiken bezüglich Proliferation an. Eine empirische Erhebung aller jemals gebauten 674 Atomkraftwerke zeigt, dass privatwirtschaftliche Motive von Anfang an keine Rolle gespielt haben, sondern militärische Interessen. Selbst bei Vernachlässigung der Kosten für den Rückbau der Atomkraftwerke und die langfristige Lagerung des Atommülls wären rein privatwirtschaftliche Investitionen in Atomkraftwerke mit hohen Verlusten verbunden – im Durchschnitt knapp fünf Milliarden Euro pro Kraftwerk, wie eine betriebswirtschaftliche Simulation zeigt. In Ländern, in denen noch Atomkraftwerke gebaut werden, wie etwa China und Russland, spielen private Investitionen auch keine Rolle. Atomkraft ist zu teuer und gefährlich und daher keine Option für eine klimafreundliche Energieversorgung.

description: We use quantum and Floer homology to construct (partial) quasi-morphisms on the universal cover of the group of compactly supported Hamiltonian diffeomorphisms for a certain class of non-closed strongly semi-positive symplectic manifolds $(M,ω)$. This leads to construction of (partial) symplectic quasi-states on the space of continuous functions on $M$ that are constant near infinity. The work extends the results by Entov and Polterovich, which apply in the closed case.
