description: Este proyecto tiene como objeto abordar la construcción de la subjetividad femenina en la novela Amora (1989), de la escritora mexicana Rosamaría Roffiel, a partir de la puesta en escena de una ficción autobiográfica. En este sentido, nos interesamos por determinar la estrecha relación entre el subgénero autobiográfico y la construcción de la subjetividad en la novela de Roffiel. Para ello nos apoyaremos en la teorización de una autorrepresentación y subjetividad en A Poetic of Women's Autobiography, donde se analiza al sujeto autobiográfico a partir del contexto histórico-cultural (Smith, 1987) y en la noción de “pacto autobiográfico”, de Philippe Lejeune (1994) y “El pacto ambiguo” de Manuel Alberca Serrano (2007).

description: Recent scanning tunneling microscopy measurements on cuprate superconductors have revealed remarkable spatial inhomogeneities in the single-particle energy gap. Using cellular dynamical mean-field theory, we study the zero temperature superconducting properties of a single-band Hubbard model with a spatial modulation of the electron density. We find that the inhomogeneity in the electronic structure results in a substantial spatial variation in the superconducting order parameter and single-particle energy gap, reminiscent of the experimental results. In particular, we find that the order parameter and gap amplitudes in the hole-rich regions are significantly enhanced over the corresponding quantities in a uniform system, if the hole-rich regions are embedded in regions with smaller hole density.

description: The evolution of the entangled muon-neutrino system emerging from charged pion decay is explored both in vacuum and in matter. The study is based on a Weisskopf-Wigner type wave-packet description. Explicit formulae are derived displaying modulation and attenuation of the oscillations due to additional time scales characterising the production process. The case of neutrinos disentangled due to the detection of the muon is also considered.

Exploring curriculum as an experience of consciousness transformation
Creators: name: Chu, (Elise) Ling-Hui
Publisher: name: University of British Columbia
Year: 2016

description: The purpose of this study is the exploration of curriculum as an experience of consciousness transformation. Moved by a deep concern over education’s inappropriate reliance on classical science, which I believe has contributed to the radical commercialization of human values, I argue for curriculum imbued with spiritual wisdoms. My argument has three parts: First, drawing on the curriculum scholarship of Dwayne Huebner, I identify openness to the transcendent and a non-dualistic worldview as two of the most prominent aspects of spiritual truth that can counter absolutism and objectivism. Second, I explore the relationship between truth and education in light of Martin Heidegger’s interpretation of Plato’s allegory of the cave and assert that the essence and purpose of education can be found in the four-stage transition of the essence of truth assumed by an individual—from taking the mere shadows as the ultimate reality to suspecting and penetrating the pretended and disguised, and then returning for the ultimate liberation of all the others. For the purpose of verifying the truthfulness of Plato’s allegory of the cave and its existential significance for human beings, my third move is to conduct a dialogue between Buddhism and quantum physics and to demonstrate a startling convergence of the two branches of thought regarding the true nature of consciousness, self and reality. On the basis of Huebner’s and other curriculum theorists’ works, Heidegger’s explication of Plato’s allegory of the cave, the dialogue between Buddhism and quantum physics, I propose the transformation of consciousness as the essence and purpose of education. Drawing specifically on the concepts and process of Buddhist spiritual practices, I explore six elements of consciousness transformation that may be helpful to educators, including understanding the nature of consciousness, self and reality, learning to appreciate human temporality, cultivating impartiality and bodhicitta, becoming responsibly responsive, cultivating selflessness, and learning to embody a non-dualistic worldview.

Desde aquí veo flores cuenta/canta la historia de un grupo de jóvenes que, motivados por una pérdida personal, deciden terminar el álbum inconcluso de su amigo fallecido y que debe enfrentarse a problemas de creación como la meta-textualidad de la música, la no traducibilidad del sistema musical al lingüístico, y la composición cohesiva, sintáctica y estética de componentes estructurales y motívico-temáticos internos. Mi propuesta dialoga, en el ámbito investigativo, con una perspectiva semióticointermedial, que concibe la transferencia, vehiculación e intercambio de significado entre medios de expresión con materiales textuales distintos. En lo que respecta al componte creativo, mi trabajo se divide en dos grandes momentos metaficcionales: uno narrativo-musical y otro musical-narrativo.

Charge sensing shows that we can reliably deplete these devices to zero charge occupancy. Measurements and simulations confirm that the energetics are determined by the gate-induced electrostatic potentials. Pauli spin blockade has been observed via transport through the double dot in the two electron configuration, a critical step in performing coherent spin manipulations in Si.

description: Este proyecto tiene como objeto abordar la novela de Betina González "Las poseídas" desde una perspectiva retroprogresiva, utilizando la hermenéutica-interpretativa como metodología. Este concepto, según su autor, implica una revisión constante de la memoria, tanto colectiva como individual, y está relacionado con diversas problemáticas acerca del papel de la memoria al momento de construir un testimonio. De modo que, a partir de esta metodología podamos hacer una lectura profunda y un diálogo con este concepto. Asimismo, en este estudio analizaremos los recursos estilísticos que crean una narración perturbadora acerca de la posesión como experiencia corpórea, examinando los elementos narrativos que emplea, los cuales van desde temas psicológicamente chocantes hasta estrategias narrativas engañosas, paradójicas o enigmatizantes, y cómo se relaciona todo esto con la imagen que el Estado, la iglesia y la sociedad proyecta en torno a las mujeres, la cual al final desemboca en una confusión o ambigüedad que la retroprogresión intentará comprender.

description: We examine the dynamics of a Bose-Einstein condensate in a symmetric double-well potential for a broad range of non-linear couplings. We demonstrate the existence of a region, beyond those of Josephson oscillations and self-trapping, which involves the dynamical excitation of the third mode of the double-well potential. We develop a simple semiclassical model for the coupling between the second and third modes that describes very satisfactorily the full time-dependent dynamics. Experimental conditions are proposed to probe this phenomenon.

The politics of contentious proximity
Creators: name: Chapelas, Katrina
Publisher: name: University of British Columbia
Year: 2016

description: How do diverse populations negotiate the terms according to which they live together within the shifting confines of urban spaces? How do these negotiations impact the social relations and hierarchies shaping daily living in cities? This dissertation explo res two cases of localized collective action in Vancouver, Canada. It argues that these actions exemplify a particular form of political contestation: the politics of contentious proximity. Both cases involve groups of urban residents who, in response to what they conceive as the incursion of new demographic groups and physical forms in “their” areas of the city, deploy representations of the identities associated with different types of people and places as a political tool. These groups frame themselves, their political adversaries and the relations of proximity that exist between them in specific, strategic terms. They do so both to establish themselves as legitimate political actors— actors with a right to a voice in determining the shape of the places in which they dwell—and to assert their entitlement to material and symbolic resources. This dissertation traces the representational strategies involved in both cases and the ways these strategies operate as processes of social construction. Further, it shows that the conceptualization and exploration of this politics has both practical and theoretical significance. It offers insight into the tactics residents use to respond to the changing demographic and physical forms of their cities, and, into the social and spatial exclusions on which these tactics are predicated. Moreover, it also makes two significant theoretical contributions. First, the politics of contentious proximity provides an alternative to two dominant lenses used to analyze urban contestation: NIMBY (not in my backyard) and ‘urban social movements’. Second, it contributes to the study of identity within political theory by suggesting an expanded conception of identity politics. It adds to our understanding of the political phenomenon of “identity”, not conceived as some deep primordial aspect of one’s individual being, as it is commonly understood, but as something actors employ and deploy, for particular and, in the cases of the actions this dissertation explores, localized, political purposes within neighbourhoods.

description: The higher dimensional cosmology provides a natural setting to treat, at a classical level, the cosmological effects of vacuum energy. Here we discuss two situations where starting with an ordinary matter field without any equation of state we end up with a Chaplygin type of gas apparently as a consequence of extra dimensions. In the second case we study the quintessential phenomena in higher dimensional spacetime with the help of a Chaplygin type of matter field. The first case suffers from the disqualification that no dimensional reduction occurs, which is, however, rectified in the second case. Both the models show the sought after feature of occurrence of \emph{flip} in the rate of expansion. It is observed that with the increase of dimensions the occurrence of \emph{flip} is delayed for both the models, more in line with current observational demands. Interestingly we see that depending on some initial conditions our model admits QCDM, $Λ$CDM and also Phantom like evolution within a unified framework. Our solutions are general in nature in the sense that when the extra dimensions are switched off the known 4D model is recovered.

A dynamical model of surrogate reactions

description: A new dynamical model is developed to describe the whole process of surrogate reactions; transfer of several nucleons at an initial stage, thermal equilibration of residues leading to washing out of shell effects and decay of populated compound nuclei are treated in a unified framework. Multi-dimensional Langevin equations are employed to describe time-evolution of collective coordinates with a time-dependent potential energy surface corresponding to different stages of surrogate reactions. The new model is capable of calculating spin distributions of the compound nuclei, one of the most important quantity in the surrogate technique. Furthermore, various observables of surrogate reactions can be calculated, e.g., energy and angular distribution of ejectile, and mass distributions of fission fragments. These features are important to assess validity of the proposed model itself, to understand mechanisms of the surrogate reactions and to determine unknown parameters of the model. It is found that spin distributions of compound nuclei produced in $^{18}$O+$^{238}$U $\rightarrow ^{16}$O+$^{240*}$U and $^{18}$O+$^{236}$U $\rightarrow ^{16}$O+$^{238*}$U reactions are equivalent and much less than 10$\hbar$, therefore satisfy conditions proposed by Chiba and Iwamoto (PRC 81, 044604(2010)) if they are used as a pair in the surrogate ratio method.

description: TeO$_2$ crystals have proven to be superb bolometers for the search of neutrinoless double beta decay in many respects. However, if used alone, they do not exhibit any feature that allows to discriminate an alpha energy deposit from a beta/gamma one. This fact limits their ability to reject the background due to natural radioactivity and eventually affects the sensitivity of the search. In this paper we show the results of a TeO$_2$ crystal where, in coincidence with its bolometric heat signal, also the luminescence light escaping the crystal is recorded. The results show that we are able to measure the light produced by beta/gamma particles, which can be explained as due to Cerenkov emission. No light is detected from alpha particles, allowing the rejection of this background source.

description: Aims: Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) remains the standard of care. CYP2C19 genetic polymorphisms cause variable clopidogrel bioactivation. Increased function (CYP2C19*17) allele carriers (rapid metabolizers [RM] or ultrarapid metabolizers [UM]) are clopidogrel hyper-responders, hence are more susceptible to clopidogrel-related bleeding. Since current guidelines recommend against routine genotyping following PCI, data on the clinical utility of CYP2C19*17 genotype guided strategy are sparce. Our study provides real-world data on the 12-month follow-up of CYP2C19 genotyping in patients post-PCI. Methods: This is a cohort study within an Irish population receiving 12-month DAPT following PCI. It identifies the prevalence of CYP2C19 polymorphisms within an Irish population and describes the ischaemic and bleeding outcomes after 12 months of DAPT. Results: A total of 129 patients were included with the following CYP2C19 polymor?phism prevalence: 30.2% hyper-responders (26.4% RM [1*/17*], 3.9% UM [17*/17*]) and 28.7% poor-responders (22.5% IM [1*/2*], 3.9% IM [2*/17*], 2.3% PM [2*/2*]). A total of 53 and 76 patients received clopidogrel and ticagrelor, respectively. At 12 months, total bleeding incidence within the clopidogrel group was positively correlated with CYP2C19 activity: IM/PM (0.0%), NM (15.0%) and RM/UM (25.0%). The positive relationship showed a moderate association that was statistically signifi?cant: rτ = 0.28, P = 0.035. Conclusions: The prevalence of CYP2C19 polymorphisms in Ireland is 58.9% (30.2% CYP2C19*17, 28.7% CYP2C19*2) with an approximately one in three chance of being a clopidogrel hyper-responder. Positive correlation between bleeding and increasing CYP2C19 activity within the clopidogrel group (n = 53) suggests possible clinical utility of a genotype-guided strategy identifying high bleeding risk with clopidogrel in CYP2C19*17 carriers, but further studies are required.

description: High-statistics measurements of differential cross sections and recoil polarizations for the reaction $γp \rightarrow K^+ Σ^0$ have been obtained using the CLAS detector at Jefferson Lab. We cover center-of-mass energies ($\sqrt{s}$) from 1.69 to 2.84 GeV, with an extensive coverage in the $K^+$ production angle. Independent measurements were made using the $K^{+}pπ^{-}$($γ$) and $K^{+}p$($π^-, γ$) final-state topologies, and were found to exhibit good agreement. Our differential cross sections show good agreement with earlier CLAS, SAPHIR and LEPS results, while offering better statistical precision and a 300-MeV increase in $\sqrt{s}$ coverage. Above $\sqrt{s} \approx 2.5$ GeV, $t$- and $u$-channel Regge scaling behavior can be seen at forward- and backward-angles, respectively. Our recoil polarization ($P_Σ$) measurements represent a substantial increase in kinematic coverage and enhanced precision over previous world data. At forward angles we find that $P_Σ$ is of the same magnitude but opposite sign as $P_Λ$, in agreement with the static SU(6) quark model prediction of $P_Σ\approx -P_Λ$. This expectation is violated in some mid- and backward-angle kinematic regimes, where $P_Σ$ and $P_Λ$ are of similar magnitudes but also have the same signs. In conjunction with several other meson photoproduction results recently published by CLAS, the present data will help constrain the partial wave analyses being performed to search for missing baryon resonances.

Critical behavior of a Ginzburg-Landau model with additive quenched noise

description: We address a mean-field zero-temperature Ginzburg-Landau, or ϕ^4, model subjected to quenched additive noise, which has been used recently as a framework for analyzing collective effects induced by diversity. We first make use of a self-consistent theory to calculate the phase diagram of the system, predicting the onset of an order-disorder critical transition at a critical value σc of the quenched noise intensity σ, with critical exponents that follow Landau theory of thermal phase transitions. We subsequently perform a numerical integration of the system's dynamical variables in order to compare the analytical results (valid in the thermodynamic limit and associated to the ground state of the global Lyapunov potential) with the stationary state of the (finite size) system. In the region of the parameter space where metastability is absent (and therefore the stationary state coincide with the ground state of the Lyapunov potential), a finite-size scaling analysis of the order parameter fluctuations suggests that the magnetic susceptibility diverges quadratically in the vicinity of the transition, what constitutes a violation of the fluctuation-dissipation relation. We derive an effective Hamiltonian and accordingly argue that its functional form does not allow to straightforwardly relate the order parameter fluctuations to the linear response of the system, at odds with equilibrium theory. In the region of the parameter space where the system is susceptible to have a large number of metastable states (and therefore the stationary state does not necessarily correspond to the ground state of the global Lyapunov potential), we numerically find a phase diagram that strongly depends on the initial conditions of the dynamical variables.

Subsurface magnetic field and flow structure of simulated sunspots

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We present a series of numerical sunspot models addressing the subsurface field and flow structure in up to 16 Mm deep domains covering up to 2 days of temporal evolution. Changes in the photospheric appearance of the sunspots are driven by subsurface flows in several Mm depth. Most of magnetic field is pushed into a downflow vertex of the subsurface convection pattern, while some fraction of the flux separates from the main trunk of the spot. Flux separation in deeper layers is accompanied in the photosphere with light bridge formation in the early stages and formation of pores separating from the spot at later stages. Over a time scale of less than a day we see the development of a large scale flow pattern surrounding the sunspots, which is dominated by a radial outflow reaching about 50% of the convective rms velocity in amplitude. Several components of the large scale flow are found to be independent from the presence of a penumbra and the associated Evershed flow. While the simulated sunspots lead to blockage of heat flux in the near surface layers, we do not see compelling evidence for a brightness enhancement in their periphery. We further demonstrate that the influence of the bottom boundary condition on the stability and long-term evolution of the sunspot is significantly reduced in a 16 Mm deep domain compared to the shallower domains considered previously.

description: We present a pedagogical case study how to combine micro-causality and unitarity based on a perturbative approach. The method we advocate constructs an analytic extrapolation of partial-wave scattering amplitudes that is constrained by the unitarity condition. Suitably constructed conformal mappings help to arrive at a systematic approximation of the scattering amplitude. The technique is illustrated at hand of a Yukawa interaction. The typical case of a superposition of strong short-range and weak long-range forces is investigated.

description: We present a class of interacting nonlocal quantum field theories, in which the CPT invariance is violated while the Lorentz invariance is present. This result rules out a previous claim in the literature that the CPT violation implies the violation of Lorentz invariance. Furthermore, there exists the reciprocal of this theorem, namely that the violation of Lorentz invariance does not lead to the CPT violation, provided that the residual symmetry of Lorentz invariance admits the proper representation theory for the particles. The latter occurs in the case of quantum field theories on a noncommutative space-time, which in place of the broken Lorentz symmetry possesses the twisted Poincaré invariance. With such a CPT-violating interaction and the addition of a C-violating (e.g., electroweak) interaction, the quantum corrections due to the combined interactions could lead to different properties for the particle and antiparticle, including their masses.

description: The article analyzes the main directions of Russian-Armenian cooperation in the energy sphere in the context of Eurasian integration. The introduction substantiates the relevance and scientific-theoretical and practical significance of the topic, as well as reveals certain aspects of the formation of the energy component of bilateral cooperation between the Russian Federation and the Republic of Armenia. The authors review in detail the legal and conceptual framework of the interaction between Russia and Armenia at both bilateral and multilateral levels (in particular, within the EAEU and CIS). In particular, they refer to the Treaty on Friendship, Cooperation and Mutual Assistance between the Russian Federation and the Republic of Armenia of August 1997, the Treaty on Long-Term Economic Cooperation until 2010 and other agreements. It is noted that energy cooperation between the two countries is largely conducted within the framework of various integration associations in the post-Soviet space - primarily, within the Eurasian Economic Union (EAEU) (since 2014). The article examines in detail the key priorities of energy cooperation between the two countries and analyzes the dynamics of their interaction. The authors identify several main areas of Russian-Armenian cooperation in the energy sector: trade in electricity and energy carriers, development of nuclear energy (including the operation of the Armenian nuclear power plant), support for the operation of energy infrastructure, as well as cooperation in the use of renewable energy sources and development of the "green" economy and energy concept. It is noted in the article that these directions of cooperation develop unevenly, which is expressed in the prevalence of traditional aspects of cooperation. Based on the results of the study, the authors conclude that Russian-Armenian cooperation in the energy sector is a significant factor not only in economic, but also in political integration in the Eurasian space. Moreover, cooperation between Russia and Armenia in this area is extremely important in terms of ensuring the energy security of the entire South Caucasus region.

temporalités

description: Cette contribution porte sur un genre de texte fréquemment demandé dans les formations initiales ou continues à l’enseignement : le bilan d’apprentissage (également nommé « bilan de formation » ou « journal d’apprentissage ») visant, entre autres, à susciter chez l’enseignant·e en formation un processus autoévaluatif. Bien que ce genre de texte soit courant, ses différentes déclinaisons font rarement l’objet d’études. Ainsi une douzaine de textes produits par divers étudiant·es (avec ou sans expérience professionnelle, enseignant·e ou formateur·rice), dans plusieurs institutions de formation à l’enseignement et de Suisse romande sont analysés selon une approche discursive. L’analyse met en lumière différentes formes d’évolutions verbalisées par les formé·es, les postures énonciatives et les points de vue qu’ils ou elles adoptent ainsi que les types de segmentation temporelle relatées dans les textes. En montrant une variété de formes d’évolution et une diversité de manières de se mettre en scène et de se regarder, nos résultats révèlent les différentes compréhensions du terme “apprendre”, quel que soit le contexte de formation et une tendance des enseignant·es à être plus descriptifs qu’analytiques. Les analyses montrent également les effets des temporalités choisies sur les engagements des enseignant·es en formation. Au final, les analyses questionnent certaines pratiques de formation en les rattachant à une problématique de littéracie universitaire.
R&D for green technologies in a dynamic oligopoly: Schumpeter, Arrow and inverted-U’s

description: We extend a well known differential oligopoly game to encompass the possibility for production to generate a negative environmental externality, regulated through Pigouvian taxation and price caps. We show that, if the price cap is set so as to fix the tolerable maximum amount of emissions, the resulting equilibrium investment in green R&D is indeed concave in the structure of the industry. Our analysis appears to indicate that inverted-U-shaped investment curves are generated by regulatory measures instead of being a "natural" feature of firms’ decisions.
Trade, externalities, and the impact of asymmetric information on trade policy

description: This paper investigates the relationship between trade liberalisation, consumers' environmental awareness and a negative environmental externality in consumption. We adopt an international Hotelling duopoly setup, where firms are located in two asymmetric countries. We find that, if the intensity of environmental externality is common knowledge for country governments, this setup delivers no need of accompanying trade policies in order to enforce trade liberalisation. In the opposite case, in which information is asymmetric, i.e., the small country's Government cannot observe the positive enviromental effects of its firm's exports to foreign consumers, we find that: (i) the Pareto optimum is always enforced, since the brown country always relaxes the distortionary trade policy, and (ii) cheating on the environmental externality allows the brown country's government to extract extra surplus from the
green country. Allowing for trade in green technology delivers opposite conclusions: the externality is minimised and welfare is maximised in equilibrium if information is symmetric while trade liberalisation with asymmetric information always entails a second best outcome.
Modelling of epitaxial film growth with a Ehrlich-Schwoebel barrier dependent on the step height

description: The formation of mounded surfaces in epitaxial growth is attributed to the presence of barriers against interlayer diffusion in the terrace edges, known as Ehrlich-Schwoebel (ES) barriers. We investigate a model for epitaxial growth using a ES barrier explicitly dependent on the step height. Our model has an intrinsic topological step barrier even in the absence of an explicit ES barrier. We show that mounded morphologies can be obtained even for a small barrier while a self-affine growth, consistent with the Villain-Lai-Das Sarma equation, is observed in absence of an explicit step barrier. The mounded surfaces are described by a super-roughness dynamical scaling characterized by locally smooth (faceted) surfaces and a global roughness exponent $α>1$. The thin film limit is featured by surfaces with self-assembled three-dimensional structures having an aspect ratio (height/width) that may increase or decrease with temperature depending on the strength of step barrier.

Production theory: accounting for firm heterogeneity and technical change

description: The paper presents a new framework to assess firm level heterogeneity and to study the rate and direction of technical change. Building on the analysis of revealed short-run production functions by Hildenbrand (1981), we propose the (normalized) volume of the zonotope composed by vectors-firms in a narrowly defined industry as an indicator of inter-firm heterogeneity. Moreover, the angles that the main diagonal of the zonotope form with the axes provide a measure of the rates and directions of technical change over time. The proposed framework can easily account for n-inputs and m-outputs and, crucially, the measures of heterogeneity and technical change do not require many of the standard assumptions from production theory.

description: Recent measurements of the Sunyaev-Zel'dovich (SZ) angular power spectrum from the South Pole Telescope (SPT) and the Atacama Cosmology Telescope (ACT) demonstrate the importance of understanding baryon physics when using the SZ power spectrum to constrain cosmology. This is challenging since roughly half of the SZ power at l=3000 is from low-mass systems with 10^13 h^-1 M_sun < M_500 < 1.5x10^14 h^-1 M_sun, which are more difficult to study than systems of higher mass. We present a study of the thermal pressure content for a sample of local galaxy groups from Sun et al. (2009). The group Y_{sph, 500} - M_500 relation agrees with the one for clusters derived by Arnaud et al. (2010). The group median pressure profile also agrees with the universal pressure profile for clusters derived by Arnaud et al. (2010). With this in mind, we briefly discuss several ways to alleviate the tension between the measured low SZ power and the predictions from SZ templates.

description: Unter dem Titel „Wiedersehen mit Hamburg“ beschreibt die 1936 aus Deutschland exilierte Grete Berges ihre Rückkehr in die Stadt, aus der sie von den Nationalsozialisten vertrieben wurde. 17 Jahre liegen zwischen Flucht und neuerlicher Ankunft der Schriftstellerin, Übersetzerin und Literaturagentin. Im Jahre 1953 begleitete sie den schwedischen Schriftsteller Per Olof Ekström, dessen Agentin sie war, auf eine Geschäftsreise nach Hamburg. Anlässlich dieser Rückkehr erschien ihr kurzer Artikel „Wiedersehen mit Hamburg“ am 22.7.1953 im Hamburger Abendblatt. Darin schildert sie die ambivalenten Gefühle beim Besuch in der Stadt, in der sie aufgewachsen war und zu der sie sich zugehörig gefühlt hatte, bis sie aufgrund ihrer jüdischen Herkunft gewaltvoll aus ihr vertrieben wurde. Auf die Frage, ob sie sich wieder dauerhaft in ihrer Geburtsstadt niederlassen wolle, fand sie deutliche Worte. Wenn sie sich auch vorstellen könne, Hamburg nochmals zu besuchen, so komme eine langfristige Rückkehr für sie nicht in Betracht. Der Artikel Berges’ steht stellvertretend für zahlreiche Exilierte, deren Karriere und Lebensweg ein abruptes Ende gefunden hatten. Doch auch nachdem die Fluchtursachen weggefallen waren, so macht Berges’ Schlussfolgerung deutlich, war eine Heimkehr und ein Wiederaufnehmen dieser abgerissenen Fäden nicht ohne Weiteres möglich. Vielmehr wirkte das Exil fort und fand mit dem Kriegsende 1945 kein Ende.
Analyzing the regional long-term development of the German power system using a nodal pricing approach

description: This work presents an optimizing energy systems model, which is used to assess the regional long-term development of the German power system until 2030. The main decision criteria for a geographically optimal power plant expansion are the locational marginal costs of electricity supply. They are determined by using a DC power flow model based nodal pricing approach. The most important results are the cost-minimizing regional power station expansions as well as the regional costs of power supply.

description: In an article titled “Wiedersehen mit Hamburg” [Return to Hamburg], writer, translator and literary agent Grete Berges, who exiled from Germany in 1936, describes her return to the city from which she was expelled by the National Socialists. Seventeen years have passed between her escape and her return visit. In 1953 she accompanied the Swedish writer Per Olof Ekström, whose agent she was, on a business trip to Hamburg. On the occasion of this return, her short article “Wiedersehen mit Hamburg” [Return to Hamburg] was published in the Hamburger Abendblatt on July 22, 1953. In it, she describes her ambivalent feelings when visiting the city where she had grown up and where she felt she belonged until she was forcibly expelled from it because of her Jewish background. When asked whether she wanted to settle permanently in her hometown again, she found clear words. Even if she could imagine visiting Hamburg again, a permanent return was out of the question for her. Berges' article is representative of numerous exiled persons whose career and personal life had come to an abrupt end. But even after the reasons for her flight had ceased to exist, Berges' conclusion makes it clear that returning home and mending these broken threads was not easily possible. Rather, her exile continued to have an effect on her and did not end with the end of the war in 1945.
