description: Modernity is usually thought as a complex society with clearly differentiated spheres of everyday life. It means, in particular, that economic rules do not interfere with the norms structuring political, social, scientific and other interactions. The complex, differentiated society sharply contrasts with a "small" and homogeneous "pre-modern" society. The process of modernization, i.e. differentiation of the spheres of everyday life, can take various forms. In an advanced country it relies on internal forces. Modernization in this context looks like an evolutionary, "bottom-up" development. In a backward country (Russia and Germany in the first half of the 20th century), modernization requires a strong governmental (from the top to the bottom) intervention. Invidious comparison with more advanced and successful countries makes the state officials in backward countries accept the way of reforms. Due to the lack of the internal forces leading to an evolutionary rise of modernity, the state officials refer to the Western experience and know-how. Consequently, a "catch-up" modernization naturally transforms into "Westernization", the transfer of Western institutions to backward countries. As the title suggests, the paper deals with the institutional problems of such a transfer of institutions, and with the constraints, imposed on the key actors of this process, the political elite. It will be argued, that a decisive problem of political and economic modernization in Russia is that bureaucrats face soft external and internal constraints. An absolute imperative consists in institutional congruence, or the "elective affinity", between the models of power relationships on which imported and traditional institutions are based. Only a passive role in carrying out reforms is reserved for non-governmental actors, which transforms their mental models into a hard constraint of reforms and prevent them from putting limits on the rulers' discretion. Consequently, there is a high risk of the transformation of modernization policies into a mechanism of the reproduction of imposed power.

description: As a part of the digital transformation, we interact with more and more intelligent gadgets. Today, these gadgets are often mobile devices, but in the advent of smart cities, more and more infrastructure---such as traffic and buildings---in our surroundings becomes intelligent. The intelligence, however, does not emerge by itself. Instead, we need both design techniques to create intelligent systems, as well as approaches to validate their correct behavior. An example of intelligent systems that could benefit smart cities are self-driving vehicles. Self-driving vehicles are continuously becoming both commercially available and common on roads. Accidents involving self-driving vehicles, however, have raised concerns about their reliability. Due to these concerns, the safety of self-driving vehicles should be thoroughly tested before they can be released into traffic. To ensure that self-driving vehicles encounter all possible scenarios, several millions of hours of testing must be carried out; therefore, testing self-driving vehicles in the real world is impractical. There is also the issue that testing self-driving vehicles directly in the traffic poses a potential safety hazard to human drivers. To tackle this challenge, validation frameworks for testing self-driving vehicles in simulated scenarios are being developed by academia and industry. In this chapter, we briefly introduce self-driving vehicles and give an overview of validation frameworks for testing them in a simulated environment. We conclude by discussing what an ideal validation framework at the state of the art should be and what could benefit validation frameworks for self-driving vehicles in the future.

description: We establish that the sequences formed by logarithms and by "fractional" powers of integers, as well as the sequence of prime numbers, are non-holonomic, thereby answering three open problems of Gerhold [Electronic Journal of Combinatorics 11 (2004), R87]. Our proofs depend on basic complex analysis, namely a conjunction of the Structure Theorem for singularities of solutions to linear differential equations and of an Abelian theorem. A brief discussion is offered regarding the scope of singularity-based methods and several naturally occurring sequences are proved to be non-holonomic.

description: Financial conglomerates and bank competition play a significant role in developing efficiencylevels and increased risk exposure. This study aims to formulate a conceptualmodel of the policy’s impact of financial conglomerates and bank competition on bankefficiency and stability risk. This research is conducted using data samples from 90commercial banks in Indonesia from 2010 to 2017. The empirical analysis is carried outusing the dynamic data panel or Generalized Method of Moments (GMM). The studyresults show that policies of financial conglomerates and competition have a positiveeffect on banking efficiency. These results support previous empirical studies, wherefinancial conglomeration, in general, can improve banking efficiency. Furthermore, itis found that the interaction between financial conglomerates and competition hasa positive effect on banking stability. The implication of this research shows that thepotential risks that cause distortion become irrelevant when the banking structure ismore competitive. Furthermore, this study recommends the need to build the idealfinancial conglomerate institutional structure to strengthen and encourage the role ofmore competitive banks.

description: Wie viele Menschen aus den mittel- und osteuropäischen Ländern (MOEL) werden von dem mit dem EU-Beitritt verbundenen Recht auf Freizügigkeit Gebrauch machen und nach Westen in die "alten" EU-Länder wandern? Die vorgestellten Simulationen ergeben eine Bandbreite für das Ost-West-Migrationspotential in der Grössenordnung von brutto jährlich 0,2% bis 0,4% der mittel- und osteuropäischen Bevölkerung, die bei einer Nettobetrachtung (unter Einbezug der Rückwanderungen) auf rund 0,1% der Bevölkerung schmilzt. Hochgerechnet auf eine erste EU-Erweiterungswelle, ergibt sich für die MOEL-8 (Slowenien, Tschechien, Ungarn, Slowakei, Polen, Estland, Litauen, Lettland) ein Ost-West-Migrations-potential, das in 15 Jahren brutto etwa 3%-4% und netto etwa die Hälfte, nämlich 1½%-2% der Bevölkerung der MOEL-8 erreicht. Dies sind rund 3 Millionen Menschen (brutto) bzw. 1-1½ Millionen Menschen (netto). Anders herum gesehen, entsprechen diese drei Millionen Menschen gerade einmal 0,8 % der EU-Bevölkerung. Mit Blick auf die zu erwartende Schrumpfung der Bevölkerung in den heutigen EU-15 Ländern und dem damit einhergehenden Alterungsprozess dürften diese Zuwanderungsbewegungen kaum negativ ins Gewicht fallen. Von einer "Völkerwanderung" kann also keine Rede sein! How many people from Central and Eastern Europe (CEEC) will go West making use of the free movement of people after the EU East enlargement? An extrapolation of the empirical experience of the EU South enlargement shows that the emigration potential might reach a corridor between 0.2% to 0.4% of total CEEC-population per year. Annual net migraton (including return migration) might be about 0.1% of total CEEC-population. If we assume that in a first wave 8 countries from CEEC will become EU members (i.e. Slovenia, Czech Republic, Hungary, Slovak Republic, Poland, Estonia, Lithuania, Latvia), the East-West migration potential will be about 3%-4% (gross) and 1½%-2% (net) of the total CEEC-population within the first 15 years after accession. This is about 3 million people (gross) resp. 1 to 1.5 million people (net) or about 0.8% of the total EU population. Therefore, fears of "mass migration" seem highly exaggerated. Muchmore, with regard to the decline of the EU population and the ageing of the society the expected East-West-migration potentials will generate rather positive consequences.

description: Recent debates about the state of Japan's financial system focus on the weakness of Japanese banks. But, in the complex financial relations of an advanced economy bank finance cannot be seen separate from other forms of financial intermediation. Despite the reform efforts under the Big Bang program, financial markets in Japan show severe signs of malfunctioning, distortion and backwardness. The paper gives an overview of the current state of markets for money, bonds, equities and derivatives arguing that for reform to become successful measures to develop an entirely different market culture were needed. It calls for a redefinition of the role of interest groups in the financial intermediation process - including the role of government.

The calculated results are shown to compare well with the recent experimental data from energetic nuclear collisions. The fluctuations in temperature and density are also studied. They are seen to build up very rapidly beyond an excitation energy of 9 MeV/u. Volume-conserving quadrupole deformation in addition to expansion indicates, however, nuclear disassembly above an excitation energy of 4 MeV/u

description: Regardless the fact that the Kyoto Protocol of the UNFCCC has not been enforced internationally yet, many industrialised nations have already become active in setting up national climate programmes. Some states like the United Kingdom and Denmark are within the implementation process of national emissions trading regimes, others - like Australia, France, the Netherlands, Norway, New Zealand and also Germany - have started consultations on such systems. Some voices argue that emissions trading does not comply with legal requirements in Germany and therefore cannot be implemented. The purpose of this discussion paper is to review literature and expert discussions on the issue and to evaluate the thesis above. A juridical evaluation of a German emissions trading system must consider both national and European legislation. Many aspects can only be evaluated theoretically today. - If one reduces all aspects of ongoing discussions to the most critical ones, only a few but still important issues remain. These are: protection of property rights, confidence and stock; principle of legal equity; potential conflicts with the final constitution and finally coherence of emissions trading and voluntary commitments. The concrete design of an emissions trading scheme - e.g. allocation method chosen - will be crucial for its legality in Germany. A close co-operation between national authorities and industry seems advisable in order to minimise resistance and conflicts.

In particular, we discuss an excess of events correlating with confirmed BL Lacs in the Veron 10th Catalog. As described in detail in Abbasi et al. (2005), the significance level of these correlations cannot be reliably estimated due to the a posteriori nature of the search, and the results must be tested independently before any claim can be made. We identify the precise hypotheses that will be tested with independent data.

description: We discuss production of charmed mesons and J/Psi in p(d)A collisions at high energies. We argue that when the saturation scale Qs characterizing the parton density in a nucleus exceeds the quark mass m, the naive perturbation theory breaks down. Consequently, we calculate a process of heavy quark production in both open and hidden channels in the framework of the parton saturation model (Color Glass Condensate). We demonstrate that at RHIC such description is in agreement with experimental data on charm production.

Phonological processes interacting with the lexicon : variable and non-regular effects in Japanese phonology
Creators: name: Rosen, Eric Robert
Publisher: name: University of British Columbia
Year: 2009

description: In current generative linguistic theory, a speaker of a natural human language possesses a language faculty that includes a lexicon: a set of language-specific input forms, and a grammar: a set of constraints or rules that derive the surface or output forms of the language from a structured combination of input forms. In Optimality Theory (Prince & Smolensky (1993)), output forms are determined by an ordered set of constraints. Constraints operate only on output forms and not input forms: thus we should expect input forms not to show the effects of a grammar and to occur in statistically random patterns. Conversely, we expect output forms to occur in patterns that are favoured by the grammar. This thesis examines apparent exceptions to both these predicted tendencies, with respect to two phonological phenomena in Japanese: (a) rendaku voicing, which causes voicing at a morpheme juncture in a compound word and (b) pitch-accent patterns of monomorphemic Yamato (native) nouns, which fail to show a predicted randomness of statistical patterns. I argue that a compound word is prone to exceptions to processes like rendaku voicing because its input form must occur partly as a minimal lexical item of its own rather than simply a concatenation of two constituent input forms. This opens up the possibility for a compound word's input form to include independent phonological features that can lexically block a process like rendaku. Here, the lexicon affects the regularity of output forms. For noun pitch-accent, I argue that apparent non-randomness of input forms is actually due to the lack of constraints on input forms in Optimality Theory. If any type of input is possible, then the surface forms of monomorphemic nouns do not necessarily reflect their input forms. Apparent non-randomness of inputs can arguably be due to a convergence of several input types on one output type, as required by the grammar, and can thus be explained as non-randomness of outputs, not inputs. In current linguistic theory, both of these claims have important implications for the nature of the lexicon, the grammar, and the way they interact.
Bimodality in the transverse fluctuations of a grafted semiflexible polymer and the diffusion-convection analogue: an effective-medium approach

description: Recent Monte Carlo simulations of a grafted semiflexible polymer in 1+1 dimensions have revealed a pronounced bimodal structure in the probability distribution of the transverse (bending) fluctuations of the free end, when the total contour length is of the order of the persistence length [G. Lattanzi et al., Phys. Rev E 69, 021801 (2004)]. In this paper, we show that the emergence of bimodality is related to a similar behavior observed when a random walker is driven in the transverse direction by a certain type of shear flow. We adapt an effective-medium argument, which was first introduced in the context of the sheared random-walk problem [E. Ben-Naim et al., Phys. Rev. A 45, 7207 (1992)], in order to obtain a simple analytic approximation of the probability distribution of the free-end fluctuations. We show that this approximation captures the bimodality and most of the qualitative features of the free-end fluctuations. We also predict that relaxing the local inextensibility constraint of the wormlike chain could lead to the disappearence of bimodality.

description: The paper develops a sequential migration model and derives a worker's optimal policies for migration and employment. With the worker's simulated reservation wage functions for employment and migration, a stationary equilibrium is defined. In that equilibrium, stationary distributions of employed and unemployed stayers and movers over different states are derived. The analysis of Markov equilibria shows that mainly unemployed skilled and unskilled migrants will migrate. I have referred to this unemployed self-selection of skilled and unskilled migrants. Furthermore, in the stationary equilibrium, a trade off between equity and efficiency is derived and represents the adverse effects when a government fosters income increases too much.
Long-Range Coulomb Effect on the Antiferromagnetism in Electron-doped Cuprates

description: Using mean-field theory, we illustrate the long-range Coulomb effect on the antiferromagnetism in the electron-doped cuprates. Because of the Coulomb exchange effect, the magnitude of the effective next nearest neighbor hopping parameter increases appreciably with increasing the electron doping concentration, raising the frustration to the antiferromagnetic ordering. The Fermi surface evolution in the electron-doped cuprate Nd$_{2-x}$Ce$_x$CuO$_4$ and the doping dependence of the onset temperature of the antiferromagnetic pseudogap can be reasonably explained by the present consideration.

description: The issue of terrestrial carbon sinks, officially labelled as Land use, Land-use change and Forestry (LULUCF) has been one of the most contentious and difficult issues in the international climate change negotiations. This study analyses the negotiation process on sinks from the third Conference of the Parties (COP 3) to COP 7 by using a multinomial logit model to identify factors influencing the negotiating positions on LULUCF of 166 Parties to the United Nations Framework Convention on Climate Change (UNFCCC). The results show that the importance of the forestry sector of a country does not seem to have affected the negotiation positions on LULUCF. However, the results suggest that the LULUCF issue was used by those Parties with a rather negative attitude towards international climate policy to reduce their Kyoto commitments. Pro-sinks Annex I Parties seem to have been motivated by the amount they were able to reduce their reduction target due to sinks, but not necessarily by the stringency of their target. By applying a zero-inflated count model, the study examines which factors influenced the participation in the submission process on LULUCF. Those Parties having taken a pro-sink position on Article 3.4 have been participating most in the submission process. The exact opposite is the case for the CDM, where the opponents of forestry projects have been the most active Parties in providing submissions. Delegation size has some, but rather modest influence on the participation in the submission process.

description: In this paper, small-angle X-ray scattering measurements are used to determine the different compressibility contributions, as well as the isothermal compressibility, in thermal equilibrium in silica glasses having different thermal histories. Using two different methods of analysis, in the supercooled liquid and in the glassy state, we obtain respectively the temperature and fictive temperature dependences of the isotheraml compressibility. The values obtained in the glass and supercooled liquid states are very close to each other. They agree with previous determinations of the literature. The compressibility in the glass state slightly decreases with increasing fictive temperature. The relaxational part of the compressibility is also calculated and compared to previous determinations. We discussed the small differences between the different determinations.
Management Practice Supporting Sustained Development In The German Art Collection

Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: The focus of this thesis lies on understanding how approaches to management can support sustained development in German art museums. This is achieved by identifying best practices in the context of sustainable outcomes, examining how historical, political and cultural trajectories shape current approaches to management in Germany, through developing an understanding of how institutions are confronting challenges in their contemporary environment and to what effect their methods align with the established best practices. Using a mixed methods approach, in the form of a comparative collective case study, interview insight as well as a quantitative assessment of indicators across a sample group of arts institutions in Germany, a range of management practices and their relationship with both the social and economic dimension of sustainability is systematically considered in contexts relevant to the German art museum. This thesis thereby explores discussions surrounding management practice and sustainability but also examines the conceptual ambivalence and tensions that arise at the intersection of the arts and theories of value within a German art museum context. By taking into account the amalgamation of political, historical and cultural undercurrents informing management, policy decisions and practice, this research is able to gain an understanding of the systemic interactions affecting the potential for sustainable development as well as limiting factors shaping management practice such as the discursive formations which shape the ways in which professionals operate. This research finds that the interactions between systems understood by key agents as incompatible or competing act as a barrier to the implementation of best practices. Through presenting four concepts that can facilitate the alignment of such systems, this research contributes new perspectives on holistic approaches to management enabling more sustainable development. The insight generated hereby can help German art museums to better serve the communities they operate within.

description: Recently, deep learning has been adopted to the glaucoma classification task with performance comparable to that of human experts. However, a well trained deep learning model demands a large quantity of properly labeled data, which is relatively expensive since the accurate labeling of glaucoma requires years of specialist training. In order to alleviate this problem, we propose a glaucoma classification framework which takes advantage of not only the properly labeled images, but also undiagnosed images without glaucoma labels. To be more specific, the proposed framework is adapted from the teacher-student-learning paradigm. The teacher model encodes the wrapped information of undiagnosed images to a latent feature space, meanwhile the student model learns from the teacher through knowledge transfer to improve the glaucoma classification. For the model training procedure, we propose a novel training strategy that simulates the real-world teaching practice named as 'Learning To Teach with Knowledge Transfer (L2T-KT)', and establish a 'Quiz Pool' as the teacher's optimization target. Experiments show that the proposed framework is able to utilize the undiagnosed data effectively to improve the glaucoma prediction performance.

description: This paper proposes a novel computational framework for the solution of geometrically parametrised flow problems governed by the Stokes equation. The proposed method uses a high-order hybridisable discontinuous Galerkin formulation and the proper generalised decomposition rationale to construct an off-line solution for a given set of geometric parameters. The generalised solution contains the information for all the geometric parameters in a user-defined range and it can be used to compute sensitivities. The proposed approach circumvents many of the weaknesses of other approaches based on the proper generalised decomposition for computing generalised solutions of geometrically parametrised problems. Four numerical examples show the optimal approximation properties of the proposed method and demonstrate its applicability in two and three dimensions.

description: In this paper we present a deep X-ray observation of the nearby M dwarf GJ 357 and use it to put constraints on the atmospheric evolution of its planet, GJ 357 b. We also analyse the systematic errors in the stellar parameters of GJ 357 in order to see how they affect the perceived planetary properties. We estimate the age of GJ 357 b by comparing the observed X-ray luminosity of its host star, derived from a recent {\em XMM-Newton} observation {($\log{L_{\rm x}}\,{\rm [erg/s]} = 25.73$), with $L_{\rm x} -$ age relations for M dwarfs. We find that GJ 357 presents one of the lowest X-ray activity levels ever measured for an M dwarf, and we put a lower limit on its age of $5$\,Gyr.} Using this age limit, we perform a backwards reconstruction of the original primordial atmospheric reservoir. Furthermore, by considering the systematic errors in the stellar parameters, we find a range of possible planetary masses, radii, and densities. From the backwards reconstruction of GJ 357 b's irradiation history we find that the upper limit of its initial primordial atmospheric mass is $\sim \rm 38M_{\oplus}$. An initial atmospheric reservoir significantly larger than this may have survived through the X-ray and ultraviolet irradiation history, hence being inconsistent with current observations that suggest a telluric composition. In spite of the unlikelihood of a currently existing primordial envelope, volcanism and outgassing may have contributed to a secondary atmosphere. Under this assumption, we present three different synthetic infrared spectra for GJ 357 b that one might expect, consisting of $100\%~\rm CO_{2}$, $100\%~\rm SO_{2}$, and $75\%~ \rm N_{2}$, $24\%~\rm CO_{2}$ and $1\%~\rm H_{2}O$.

description: Enterprise data integration is the process of combining data from multiple sources to fulfil business and market needs. Traditional approaches such as shared databases and messaging-oriented systems fall short of new challenges to keep pace with the evolution of big data in changing markets. Such challenges can be observed at two levels. First, during integration design we need to establish a concise, visual and loosely-coupled mapping to support data integration without disturbing internal business process and applications. Second, at the execution level we need to support efficient bidirectional transformations and synchronisations to respond to evolving requirements in a cost-effective manner. Graph databases such as neo4j are designed to handle and integrate big data from heterogeneous sources using efficient navigation based query languages such as Gremlin. For flexibility and performance, they do not ensure data quality through schemata but leave it to the application level. They are built on top of a rich data model that can be utilised to realise the interconnectedness of real-world data domains. On the other hand, model-driven design and implementation techniques have been widely adopted to build systems at a high level of abstraction. They exploit visual relational models such as the Unified Modelling Language (UML) to describe systems at various stages of development and allow to automatically generate application logic. In this thesis, we present a model-driven approach to bidirectional transformations and synchronisations between relational sources in neo4j. We describe data sharing between relational sources using declarative Triple Graph Grammars (TGGs), then compile them into query and update operations in Gremlin to execute controlled transformations and synchronisations in neo4j using a Model-To-Text (M2T) transformation approach. To ensure the validity and the efficiency of our approach, we evaluate the correctness and the performance of generated Gremlin queries using well-known bidirectional transformations testing suites. The results show that our approach is valid and efficient to support enterprise data sharing and synchronisations. The approach combines the data quality of schema-based solutions while utilising the performance of Gremlin queries on neo4j to perform loosely coupled incremental data transformations for data driven applications.
The Lost Decade: The Fortunes and Films of the 'Hollywood Renaissance Auteur' in the 1980s

description: The dominant view of late 1960s and early 1970s American film history is that of a ‘Hollywood Renaissance’, a relatively brief window of artistry and critique based around a select group of directors. In contrast, the 1980s are routinely seen as the era of the blockbuster and of ‘Reaganite entertainment’. While key directors associated with the Renaissance period remained active throughout the 1980s, this work has been obscured by a narrow, singular model of American film history, which has placed undue emphasis on White House occupancy and box-office hits. This is an analysis of 1980s American film history, and of authorship, from a fresh perspective, through the prism of a group of filmmakers who had been lavished with praise for their 1970s films but whose subsequent careers have routinely been dismissed in perfunctory terms. Indeed, the 1980s careers of directors like Robert Altman, Francis Coppola and William Friedkin, far from conforming to a monolithic pattern of decline, show diverse and complex responses to societal and industrial changes. While this is a project that is concerned with industrial contexts, it is also very much about individual films, bringing to light a range of unheralded or obscure work that seems particularly suited to an auteurist interpretation, from the visual experimentation of One from the Heart (Coppola, 1981) to the experimental production contexts of Secret Honor (Altman, 1984) and the stylistic élan of To Live and Die in L.A. (Friedkin, 1985). Behind the homogenous picture of the decline of the auteur in 1980s American cinema are films and careers that merit greater attention and this study offers a new position from which to appreciate individual films, American film history, and the viability of sustained authorial creativity within post-studio era Hollywood.
Obtaining Stiffness Exponents from Bond-diluted Lattice Spin Glasses

description: Recently, a method has been proposed to obtain accurate predictions for low-temperature properties of lattice spin glasses that is practical even above the upper critical dimension, $d_c=6$. This method is based on the observation that bond-dilution enables the numerical treatment of larger lattices, and that the subsequent combination of such data at various bond densities into a finite-size scaling Ansatz produces more robust scaling behavior. In the present study we test the potential of such a procedure, in particular, to obtain the stiffness exponent for the hierarchical Migdal-Kadanoff lattice. Critical exponents for this model are known with great accuracy and any simulations can be executed to very large lattice sizes at almost any bond density, effecting a insightful comparison that highlights the advantages -- as well as the weaknesses -- of this method. These insights are applied to the Edwards-Anderson model in $d=3$ with Gaussian bonds.

Frequency dependent dielectric response of ferroelectric-dielectric junction with negative electric capacitance

description: We calculated the frequency dependent dielectric response (electric susceptibility) of layered ferroelectric-dielectric junction, biased by the time-dependent harmonic voltage with single frequency $ω$. Working point is stabilized, by the charge boundary condition between the layers, in the region with negative electric capacitance. The static susceptibility $χ_0$ is negative and relative dielectric constant $ε_r$ smaller than one, clearly indicating the opposite direction of electric field and polarization in the ferroelectric layer due to the negative electric capacitance. At finite frequencies this sign is preserved in real part of susceptibility which gains the frequency dependence. Also, frequency dependent imaginary part arises due to the phase shift between electric field and polarization. The type of that frequency dependence in linear regime is so-called relaxation (Debye) response, i.e. $χ'(ω)=χ_0/(1+(τω)^2)$ and $χ"(ω)=χ_0τω/(1+(τω)^2)$, where $τ$ is polarization switching time characteristic to ferroelectric material. In particular, we modeled the junction of ferroelectric BaTiO$_3$ and dielectric Al$_2$O$_3$, taking the experimental values of material parameters, and addressed the role of nonlinearity with respect to result of the linear response theory.

description: Several mathematical views of phase-locking are developed. The classical Huyghens approach is generalized to include all harmonic and subharmonic resonances and is found to be connected to 1/f noise and prime number theory. Two types of quantum phase-locking operators are defined, one acting on the rational numbers, the other on the elements of a Galois field. In both cases we analyse in detail the phase properties and find them related respectively to the Riemann zeta function and to incomplete Gauss sums.

description: We apply ideas of the parquet-diagram and optimized Fermi-hypernetted chain methods to determine the short-range structure of the pair wave function in neutron matter and compare these with Bethe-Goldstone results and those of low-order variational calculations. It is shown that the induced interaction, describing the exchange of density, spin, and tensor fluctuations, has a profound influence on the short-ranged structure of the pair wave function and, hence, on effective interactions in neutron matter.

description: It is widely accepted that topological quantities are useful to describe quantum liquids in low dimensions. The (spin) Hall conductances are typical examples. They are expressed by the Chern numbers, which are topological invariants given by the Berry connections of the ground states. We present a topological description for the (spin) Hall conductances on a discretized Brillouin Zone. At the same time, it is quite efficient in practical numerical calculations for concrete models. We demonstrate its validity in a model with quantum phase transitions. Topological changes supplemented with the transition is also described in the present lattice formulation.

description: This paper presents a new equilibrium framework for analyzing economic and policy questions related to the sorting of households within a large metropolitan area. We estimate the model using restricted-access Census data that precisely characterize residential and employment locations for households the San Francisco Bay Area, yielding accurate measures of preferences for a wide variety of housing and neighborhood attributes across different types of household. We use these estimates to explore the causes and consequences of racial segregation in general equilibrium. Our results indicate that, given the preference structure of households in the Bay Area, the elimination of racial differences in income and wealth would significantly increase the residential segregation of each major racial group, as the equalization of income leads, for example, to the formation of new wealthy, segregated Black and Hispanic neighborhoods. We also provide evidence that sorting on the basis of race itself (whether driven by preferences or discrimination) leads to large reductions in the consumption of housing, public safety, and school quality by Black and Hispanic households.
