description: We study Heisenberg antiferromagnets with nearest- (J1) and third- (J3) neighbor exchange on the square lattice. In the limit of large spin S, there is a zero temperature (T) Lifshitz point at J3 = (1/4) J1, with long-range spiral spin order at T=0 for J3 > (1/4) J1. We present classical Monte Carlo simulations and a theory for T>0 crossovers near the Lifshitz point: spin rotation symmetry is restored at any T>0, but there is a broken lattice reflection symmetry for 0 <= T < Tc ~ (J3-(1/4) J1) S^2. The transition at T=Tc is consistent with Ising universality. We also discuss the quantum phase diagram for finite S.

description: This paper presents the results of experimental investigation of unsteady flows in a concentric circular annulus. The flow is generated by the controlled motion of a piston. A range of Reynolds number and boundary layer thickness is obtained by changing the piston velocity and piston displacement. Velocity profiles during deceleration of the flow are with reverse flow near the wall and are highly unstable due to their inflectional nature. The unstable flow ends in periodic vortices at walls of inner and outer pipes. Any arbitrary piston motion is expressed in terms of Fourier series and the generalized analytical solution is obtained for an arbitrary unsteady volume flow rate through the concentric pipe annulus. The velocity profiles for the experimental cases are obtained from the analytical solution. These mean velocity profiles are used for quasi-steady 3D linear stability analysis. The quasi-steady 3D linear stability analysis is used to explain the observed instability and transition to turbulence in experiments details of which will be presented in final paper.

description: Banks extract large profits through speculative trading on the foreign exchange markets and some authors have argued that banks are the winners and that the traders of goods and services are the losers in this game of foreign exchange dealing. The author argues that banks earn a return through providing a service of smoothing exchange rates over time and that this represents a benefit to international traders in other markets. It is argued that the banks' speculative trade raises economic efficiency in the real economy by reducing the volatility of exchange rates. JEL Codes: F31, G21

Coastal rural village planning with visual simulation at Miners Bay, Mayne Island
Creators: name: Xu, Qing
Publisher: name: University of British Columbia
Year: 2011

description: This project describes different possibilities for compatible development in a small rural coastal community, Miners Bay on Mayne Island, and uses computerized 3D tools to depict the development options in order to develop, test and revise the design. The site is the core of Miners Bay where the commercial and community center of Mayne Island has been located for more than 100 years. Mayne Island is part of the southern Gulf Islands chain of British Columbia. Its geographical location is in Active Pass, a busy waterway between Vancouver Island and the lower mainland. The community is rich in historical features and presents unique beautiful ocean views. The residents have desires for a more sustainable form of development. Information from a previous project in Landscape architecture at UBC provided an understanding of landscape features at the local level (Mayne Island). General landscape character and building character, circulation and orientated ocean views established the key criteria for landscape conservation, view protection, and community development to be explored in the design. Two community development scenarios were developed to examine expansion of shoreline-oriented commercial tourism development while protecting rural character and ocean views, under existing and alternative planning resolutions. 3D modeling and computer animation were used as a major tool in the stages of project inventory, site analysis and conceptual design and processed vital in demonstrating and testing the spatial results of plans. Recommendations for revising current planning policies include more specific protection of key view corridors to the ocean; clustering of new commercial tourism development to protect key views, improving building orientation to the ocean, and creating a denser commercial area and dispensing building pattern in the village; as well as other community design options to increase community viability while retaining the rural character.

description: Over the past decades, classification models have proven to be essential machine learning tools given their potential and applicability in various domains. In these years, the north of the majority of the researchers had been to improve quantitative metrics, notwithstanding the lack of information about models' decisions such metrics convey. This paradigm has recently shifted, and strategies beyond tables and numbers to assist in interpreting models' decisions are increasing in importance. Part of this trend, visualization techniques have been extensively used to support classification models' interpretability, with a significant focus on rule-based models. Despite the advances, the existing approaches present limitations in terms of visual scalability, and the visualization of large and complex models, such as the ones produced by the Random Forest (RF) technique, remains a challenge. In this paper, we propose Explainable Matrix (ExMatrix), a novel visualization method for RF interpretability that can handle models with massive quantities of rules. It employs a simple yet powerful matrix-like visual metaphor, where rows are rules, columns are features, and cells are rules predicates, enabling the analysis of entire models and auditing classification results. ExMatrix applicability is confirmed via different examples, showing how it can be used in practice to promote RF models interpretability.

description: Die vorliegende Diplomarbeit beschäftigt sich mit der baulichen Entwicklung der ehemaligen DDSG-Werft (Donau-Dampfschifffahrtsgesellschaft) in Korneuburg, die 1852 formell gegründet und 1993 in ihrem Betrieb aufgelassen wurde. Auf Basis von Literatur, bisher nicht veröffentlichtem historischem Planmaterial, historischem Fotomaterial sowie Zeitzeugenangaben wird die Baugeschichte der Werft im Allgemeinen wie auch jene der Arbeiterkolonie sowie einzelner Industriegebäude textlich und grafisch rekonstruiert. Der Einfluss der beiden Architekten Othmar von Leixner und Alexander Popp auf die bauliche Entwicklung stellt ebenfalls einen zentralen Aspekt dieser Arbeit dar. In weiterer Folge sollen zusammenfassend Charakteristik und Wert der jeweiligen Objekte festgestellt werden. Den Abschluss der Arbeit bildet die Untersuchung der Baulichkeiten am Werftareal hinsichtlich der behördlichen Zuständigkeit des Bundesdenkmalamtes sowie die denkmalpflegerische Wertefeststellung in Anlehnung an die Theorien von Alois Riegl und Max Dvoák.
description: This diploma thesis explores the physical and structural development of the former DDSGshipyard (Donau-Dampfschifffahrtsgesellschaft) in Korneuburg, which was formally founded in 1852 and shut down in 1993. Based on relevant literature, previously undisclosed plans and blueprints, historical photographs and oral history, the shipyard's building history in general as well as the history of the 'Arbeiterkolonie' and individual industrial buildings is reconstructed. Othmar von Leixner's and Alexander Popp's architectural influences on the development of the buildings are addressed as they represent another central aspect of this thesis. In further consequence, the characteristics and value of the respective objects are determined. The last part of the thesis focusses on analysing the area's buildings with regard to the administrative authority of the Federal Monuments Office (Bundesdenkmalamt) as well as the evaluation of cultural heritage preservation following the theories of Alois Riegl and Max Dvoák.

description: The author states that empirical evidence suggests that two types of speculator currently exist in the foreign exchange markets: the first type of speculator simply follows trend movements in exchange rates; the second type anticipates the turning point in trends and thereby turns such runs around. The first type of trade is destabilising and the second type helps to maintain stability. However, both types depend upon an unstable system. Rational operators who attempt to determine fundamental equilibriums appear irrational in terms of the profits they earn. This constitutes a paradox for economic theorists. JEL Codes: F31, G21

description: Some people consider that economics has undergone something of a crisis in recent years and that it has promised more than it can live up to. In this article, Kurt W. Rothschild presents his view on the state of a subject that he has studied since 1934. His methodological position is that economics cannot be a hard science and that ‘exactness’ outside of the realm of ‘logical’ models is futile. A multi-paradigmatic approach is necessary, and we should remember that all sorts of methods, both orthodox and unorthodox, have contributed to new insights and theories. The article is a contribution to a series of recollections and reflections on the professional experiences of distinguished economists which the Banca Nazionale del Lavoro Quarterly Review started in 1979.

QSO lensing magnification associated with galaxy groups

description: We simulated both the matter and light (galaxy) distributions in a wedge of the universe and calculated the gravitational lensing magnification caused by the mass along the line of sight of galaxies and galaxy groups identified in sky surveys. A large volume redshift cone containing cold dark matter particles mimics the expected cosmological matter distribution in a flat universe with low matter density and a cosmological constant. We generate a mock galaxy catalogue from the matter distribution and identify thousands of galaxy groups in the luminous sky projection. We calculate the expected magnification around galaxies and galaxy groups and then the induced QSO-lens angular correlation due to magnification bias. This correlation is an observable and can be used to estimate the average mass of the lens population and also make cosmological inferences. We also use analytic calculations and various analysis to compare the observational results with theoretical expectations for the cross-correlation between faint QSOs from the 2dF Survey and nearby galaxies and groups from the APM and SDSS EDR. The observed QSO-lens anti-correlations are stronger than the predictions for the cosmological model used. This suggests that there could be unknown systematic errors in the observations and data reduction, or that the model used is not adequate. If the observed signal is assumed to be solely due to gravitational lensing then the lensing is stronger than expected, due to more massive galactic structures or more efficient lensing than simulated.

description: The creation of the single European banking market will result in a much larger market than the sum of the various national segments; even the qualitative characteristics of the single market will differ from those of any one national component. European credit intermediaries are now required to undertake major structural changes. In particular, these changes will effect banking systems that are still not very internationalised, often coming about from experiences of protecting the internal market. In this context, the authors investigate the unification of the European credit market, the internationalization of the European banking systems, and the specialisation and comparison of the major Italian groups.

description: Die Diplomarbeit widmet sich der Untersuchung der Baugeschichte der "Favorita auf der Wieden" - das heutige Theresianums. Als Grundlage dient das umfassende Werk von Architekt Dr. Erich Schlöss mit dem Titel 'Die Baugeschichte des Theresianums in Wien', 1998. Ausgehend von der ersten urkundlichen Erwähnung im Mittelalter als Gutshof, ausgebaut zur kaiserlichen Residenz der Favorita, bis hin zur gegenwärtigen Nutzung als Bildungsstätte wird die gesamte Entwicklung des heutigen Gebäudekomplexes dargestellt. Anschließend richtet sich der Blick auf die Bildungsreform durch Maria Theresia. Das dritte Kapitel widmet sich den aktuellen Tendenzen im Schulbau und den damit einhergehenden pädagogischen Konzepten, aus welchen die aktuellen Nutzungsdefizite des Theresianums herausgearbeitet wurden. Anschließend beschäftigt sich die Arbeit mit der Rechtslage zum Thema Dachgeschoßausbau nach der Wiener Bauordnung. Unter Einbeziehung der zuvor behandelten Themen erfolgt der architektonische Entwurf: Ein Ausbau des Dachbodens des zentral gelegenen Reitschulhoftraktes mit dem Ziel, diesen unter Berücksichtigung des historischen und denkmalgeschützen Bestandes, mit belebten Volumina in Form von neuen Lernräumen zu bespielen.
description: The thesis is devoted to the study of the architectural history of the "Favorita auf der Wieden" - today's Theresianum. As a basis serves the comprehensive work of architect Dr. Erich Schlöss called "The architectural history of the Theresianum in Vienna", 1998. Starting from its first mention in the Middle Ages as a farm, the imperial residence of the Favorita constantly expanded until to its current usage as an educational. A short overview on the development of the building complex is represented in this thesis. Furthermore, there is a focus on the educational reforms by Maria Theresia. The third chapter is devoted to current trends in school construction and the associated educational concepts, from which the current deficiencies of the schoolbuilding were identified. In addition, the work deals with the Viennese building codes for Loft extensions. Taking into account the above topics, an architectural design proposal is provided: An expansion of the attic of the central riding school yard tract with the aim of taking into account the historical and landmarked portfolio as well as providing new forms of learning spaces.
Interpretazioni di Keynes: logica del probabile, strutture dell'incerto

Publisher: name: Moneta e Credito
Year: 2013
Subjects: subject: Keynes, philosophy
subject: E12

description: The work concerns the seemingly inexhaustible theme of chance and uncertainty in Keynes’ thought, inspired by the book On Keynes' Method by Anna M. Carabelli. While in the past there was much debate on Keynes the economist and little on Keynes the philosopher, today the situation is almost entirely reversed. Within this new literary "boom" Carabelli's book holds a clearly differentiated thesis that is supported so strongly, that it can not go unnoticed. The precise argument is that Keynes’ method comes from a philosophy of knowledge whose foundations and distinctive features are fully developed in the Treatise on Probability. The examination of this work, the intentions that move it and the results that are affirmed, demonstrate that, in order to become the economist that we know today, Keynes had to get rid of his philosophy of probability. The contrast between these convictions and the main theses supported by Carabelli is the reason for the counter-interpretation of Keynes’ texts presented here. JEL Codes: E12

title: Development of a Robotic Positioning and Tracking System for a Research Laboratory
Creators: name: Nneji, Stephen Obiajulu
Publisher: name: The Open University
Year: 2017

description: Measurement of residual stress using neutron or synchrotron diffraction relies on the accurate alignment of the sample in relation to the gauge volume of the instrument. Automatic sample alignment can be achieved using kinematic models of the positioning system provided the relevant kinematic parameters are known, or can be determined, to a suitable accuracy. The main problem addressed in this thesis is improving the repeatability and accuracy of the sample positioning for the strain scanning, through the use of techniques from robotic calibration theory to generate kinematic models of both off-the-shelf and custom-built positioning systems. The approach is illustrated using a positioning system in use on the ENGIN-X instrument at the UK’s ISIS pulsed neutron source comprising a traditional XYZΩ table augmented with a triple axis manipulator. Accuracies better than 100microns were achieved for this compound system. Although discussed here in terms of sample positioning systems these methods are entirely applicable to other moving instrument components such as beam shaping jaws and detectors. Several factors could lead to inaccurate positioning on a neutron or synchrotron diffractometer. It is therefore essential to validate the accuracy of positioning especially during experiments which require a high level of accuracy. In this thesis, a stereo camera system is developed to monitor the sample and other moving parts of the diffractometer. The camera metrology system is designed to measure the positions of retroreflective markers attached to any object that is being monitored. A fully automated camera calibration procedure is developed with an emphasis on accuracy. The potential accuracy of this system is demonstrated and problems that limit accuracy are discussed. It is anticipated that the camera system would be used to correct the positioning system when the error is minimal or notify the user of the error when it is significant.

description: The recent attention for quinoa as a highly nutritious “superfood” and the consequent increase in international quinoa trade is changing the production and consumption of quinoa among smallholder farmers in Andean regions, where the crop originates from. Quinoa is converting from a common staple and subsistence crop into a high-value cash crop. The rapid rise in international quinoa prices creates a concern about quinoa consumption – and consequent implications for nutrition – among Andean farm-households. In this paper, we estimate the own price elasticity of consumption of quinoa for quinoa-producing farm-households in the Peruvian Andes. We rely on the seminal Barnum-Squire farm-household model to explain the effects of food price changes that simultaneously affect farm-households’ consumption and production decisions. We apply the theoretical model to original farm-household survey data from Junín, a traditional quinoa producing region in Peru. The estimates show that a 1% increase in the quinoa price results in a 0.429% increase in quinoa production and a 0.238% increase in its consumption. Our finding of a positive own price elasticity of consumption of quinoa suggests that the global quinoa boom did not adversely affect the nutritional intake of smallholder quinoa producers.

description: The heavy ion total cross section for continuum e+ e- pair production has been calculated to all orders in Z alpha. The formula resulting from an exact solution of the semiclassical Dirac equation in the ultrarelativistic limit is evaluated numerically. An energy dependent spatial cutoff of the heavy ion potential is utilized, leading to an exact formula agreeing with the known perturbative formula in the ultrarelativistic, perturbative limit. Cross sections and sample momentum distributions are evaluated for heavy ion beams at SPS, RHIC, and LHC energies. e+ e- pair production probabilities are found to be reduced from perturbation theory with increasing charge of the colliding heavy ions and for all energy and momentum regions investigated.

description: Mitten in den Südtiroler Alpen liegt die 1897 erbaute Stettiner Schutzhütte. Sie liegt in lawinengefährdetem, hochalpinem Gelände (2875 m)und ist ein strategisch wichtig gelegener Ausganspunkt für viele alpine Touren in den Ötztaler Alpen. Im Februar 2014 wurde sie größtenteils von einer Lawine zerstört. Ich möchte mich in meiner Diplomarbeit mit dem Wiederaufbau der Stettiner Schutzhütte beschäftigen. Aspekte, auf die ich in Besonderem eingehen will, sind der Einfluss touristischer Ansprüche auf die Architektur von modernen Schutzbauten und das Bauen in alpiner Landschaft im Spannungsfeld zwischen idyllischer Natur und steigendem Touristendruck in den Alpen. Außerdem möchte ich mich mit dem Einsatz moderner Technologie zur Bewältigung von schwierigen Verhältnissen, wie zum Beispiel erschwerte Zugänglichkeit in der Bauphase, extreme Witterungsverhältnisse und hohe Ansprüche an die Energieeffizienz des Gebäudes beschäftigen. Abschließend werde ich noch auf die unterschiedlichen Sinneserfahrungen eingehen, die wir durch unterschiedliche Materialien und Formen wahrnehmen.
description: The Stettiner Hütte is a refuge in the center of the Alps in South Tyrol since 1897. It is located in high alpine terrain at 2875 m altitude and continuously threatened by avalanches. For the alpine tourism it is a strategically important refuge in the Ötztaler Alps. In February 2014 an avalanche destroyed the building. In my diploma thesis I want to focus on the reconstruction of the Stettiner refuge taking into account the following aspects: the influence of touristic requirements on the architecture of modern protection buildings, the construction in the landscape between dyllic nature and the increasing quantity of alpine tourists and the use of modern technologies to cope with difficulties regarding logistics, climatic circumstances and energetic efficiency. Furthermore I would like to consider how the use of different materials and forms influence our sensory perception.

description: We study the effect of a single columnar pin on a $(1+1)$ dimensional array of vortex lines in planar type II superconductors in the presence of point disorder. In large samples, the pinning is most effective right at the temperature of the vortex glass transition. In particular, there is a pronounced maximum in the number of vortices which are prevented from tilting by the columnar defect in a weak transverse magnetic field. Using renormalization group techniques we show that the columnar pin is irrelevant at long length scales both above and below the transition, but due to very different mechanisms. This behavior differs from the disorder-free case, where the pin is relevant in the low temperature phase. Solutions of the renormalization equations in the different regimes allow a discussion of the crossover between the pure and disordered cases. We also compute density oscillations around the columnar pin and the response of these oscillations to a weak transverse magnetic field.

description: Es gehört zur Tradition der Professur Baubetrieb und Bauverfahren, den Studenten ausführliche Lehrunterlagen in die Hand zu geben, mit deren Hilfe sie sich in dem umfassenden Lehrgebiet orientieren und in der Vorlesung konzentrierter dem Verständnis des Stoffes widmen können. Diese Broschüre ist vor allem Lehrmaterial, das kostengünstig der Rationalisierung des Lehrbetriebes im universitären Bachelorstudium dienen soll. Deshalb waren typografische Kompromisse zugunsten der Wirtschaftlichkeit unausweichlich. Die Ausarbeitung folgt der Logik des zu vermittelnden Wissens, ist aber nicht streng mit Vorlesungsprogramm und -inhalten verknüpft. Einer kurzen Einführung in das Fach „Baubetriebswesen“ folgen die produktionstechnischen Grundlagen anhand der Kernprozesse der Bauproduktion: Erdbau, Betonbau und Montagebau. Auf dieser Basis werden auch die Grundlagen der Baustelleneinrichtung im nächsten Kapitel verständlich. Im Teil „Baubetrieb“ wird schließlich gezeigt, wie die produktionstechnischen Prozesse geordnet, geplant, vertraglich gebunden, in der Ausführung überwacht und abgerechnet werden. Die in allen Kapiteln relevanten personengebundenen Faktoren runden schließlich mit arbeitswissenschaftlichen und arbeitsschutztechnischen Grundlagen diese Einführung in das Baubetriebswesen ab.

Role of tumor suppressor p33ING2 inhuman cutaneous melanoma
Creators: name: Lu, Fuqu
Publisher: name: University of British Columbia
Year: 2011

description: P33JNG2 was cloned through a homology search with p33INGlb, the founding member of ING family proteins in 1998. There have been several studies indicating that p331NG2 is a tumor suppressor candidate since it is involved in the regulation of transcription, apoptosis and senescence. People in our lab already revealed that p33ING2 plays an essential role in cellular stress response against UV irradiation (UVR) either by enhancing nucleotide excision repair (NER) or promoting apoptosis in melanoma cell line. So far, reduced ING family proteins have been reported in different tumor types including the loss of nuclear expression of p33INGlb in melanoma. Since p33ING2 is highly homologous to p331NGlb, we hypothesized that aberrant expression of p331NG2 may play a role in melanoma tumorigenesis. To test this hypothesis, we used tissue microarray (TMA) and immunohistochemistry to evaluate the expression pattern of p33ING2 in different stages of melanocyte lesions. We found that nuclear 1NG2 expression is significantly reduced in melanomas compared with dysplastic nevi. Moreover, there is no correlation between TNG2 nuclear expression and patient clinicopathological parameters or between 1NG2 nuclear expression and patient's 5-year survival in primary melanomas and metastatic melanomas. We then investigated if gene mutation is the reason for reduced ING2 nuclear expression in melanomas. Our results showed that no mutation is found in melanoma cell lines or melanoma tissue samples. At last, we restored the expression of p33TNG2 in melanomas by establishing the 1NG2 stable cell line, and cDNA microarray analysis was performed to identify the most abundantly induced or suppressed genes by overexpressed ING2 or UVR. We found that UVR can enhance expressions of two relatively new genes BTG2 and PLK3 while stably expression of p33ING2 significantly decreased RARRES1 (TIG1) expression.
La teoria monetaria e la determinazione dei prezzi fissi e flessibili: una valutazione di A Market Theory of Money di John Hicks

Subjects: subject: John Hicks, A market theory of money, SI-LL
subject: B22, B31, E30

description: The work represents an analysis of Sir John Hick’s book A market theory of money. Sir John has, on a number of occasions, taken his distance from the SI-LL model and what has been made of it in mainstream economics. He has never done this with respect to his own approach to money, or discussed why, given the initial similarity with Keynes’ approach to liquidity, he went on to develop a diverse approach. It is this difference which will be the centre of our discussion. JEL Codes: B22, B31, E30

description: The coexistence of weak ferromagnetism and superconductivity in ErNi$_{2}$B$% _{2}$C suggests the possibility of a spontaneous vortex phase (SVP) in which vortices appear in the absence of an external field. We report evidence for the long-sought SVP from the in-plane magnetic penetration depth $Δλ(T)$ of high-quality single crystals of ErNi$_{2}$B$_{2}$C. In addition to expected features at the Néel temperature $T_{N}$ = 6.0 K and weak ferromagnetic onset at $T_{WFM}=2.3 $K, $Δλ(T)$ rises to a maximum at $T_{m}=0.45$ K before dropping sharply down to $\sim $0.1 K. We assign the 0.45 K-maximum to the proliferation and freezing of spontaneous vortices. A model proposed by Koshelev and Vinokur explains the increasing $Δλ(T)$ as a consequence of increasing vortex density, and its subsequent decrease below $T_{m}$ as defect pinning suppresses vortex hopping.

description: This brief reflects on the cases of two villages in Lingoni section, Domasi EPA in Machinga district, combined with literature review and key informant interviews, to highlight the significant contribution of village-level responsible governance in enhancing agroecological intensification amongst small holders. The study reveals that through using village by-laws as tools, successful control of free grazing of livestock and uncontrolled fires has been prevented for many years, allowing local cropping systems to embrace long season crops such as cassava and pigeon peas, and winter cropping including multiple cropping with irrigation. The full range of resulting agroecological benefits are presented and discussed including the trade-offs from all sides of the systems.

description: Türkische Städte werden seit 2003 einer neuen Welle räumlicher und gouvernementaler Restrukturierungen ausgesetzt. Istanbul nimmt mit mehr als hundert Stadterneuerungsprojekten einen besonderen Platz in diesem Prozess ein. Die aus einer breiten Platte von Gründen initiierten Projekte laufen aber nicht einfach reibungslos ab, sondern stellen einen durch diverse Akteure und verschiedene Praktiken umkämpften Bereich dar. In dieser Arbeit wird daran anknüpfend die Stadterneuerung und die Gegenpraktiken dazu als ein ungleicher "Krieg mit anderen Mitteln" untersucht. Die Metapher des Krieges ermöglicht es, die verschiedenen Praktiken anhand der Begriffe Strategie und Taktik zu diskutieren. Dabei werden zwei Projekte in den historischen Vierteln im Stadtkern, Sulukule und Tarlaba, ausführlich behandelt. Beide Viertel beherbergten eine physisch verfallene Bausubstanz, was für die arme Bevölkerungsschicht der Stadt Überlebensmöglichkeiten bot. Beide Projekte haben nicht nur diese Bausubstanz zerstört, sondern auch die Bewohnerstruktur des Viertels vollkommen verändert. Beide Stadterneuerungsprojekte haben zwar in dieser Hinsicht Ähnlichkeiten, weisen aber unterschiedliche Strategien und Taktiken auf - sowohl von den Initiatoren der Stadterneuerung als auch den Bewohnern und Aktivisten.
description: Since 2003 Turkish cities have undergone a new wave of spatial and governmental restructuring. Istanbul has a special place in this process with more than one hundred urban transformation projects. The implementation of these projects, initiated for a broad range of reasons, is not simply smooth nor without tensions; diverse actors contest them through different practices. This work considers Urban Transformation and the counter practices as an uneven 'war by other means'. The metaphor of war enables analysis of the different practices with the help of notions of strategy and tactic. Two urban renewal projects in the historical neighborhoods of the city center, Sulukule and Tarlaba were analyzed in depth. Both neighborhoods contained physically deteriorated building stock that provided the urban poor with means to survive. The new projects not only destroyed the building stock, but also changed the inhabitant profile entirely. The urban renewal processes in both neighborhoods have similarities in this regard; however they demonstrated differences in terms of strategies and tactics used by the initiators of the urban renewal, as well as by residents and activists.
Contributi econometrici della Cowles Commission, 1944-47: uno sguardo retrospettivo
Creators: name: KLEIN, L.R.
Publisher: name: Moneta e Credito

Subjects: subject: Econometrics, Cowles commission
subject: B23

description: The Cowles Commission's econometric work had a profound effect on economic analysis after the Second World War. Econometrics was a young discipline at that time and the author discusses the principle contributors and their work at the Cowles Commission for Research in Economics. Successful econometrics relies on combining economics with mathematics and statistics. It is also important to remember that quantitative economics does not give results that are robust in very small confidence areas - rather they provide guidance for policy makers and facilitate a better understanding of the economy.

description: We study decoherence due to low frequency noise in Josephson qubits. Non-Markovian classical noise due to switching impurities determines inhomogeneous broadening of the signal. The theory is extended to include effects of high-frequency quantum noise, due to impurities or to the electromagnetic environment. The interplay of slow noise with intrinsically non-gaussian noise sources may explain the rich physics observed in the spectroscopy and in the dynamics of charge based devices.
