description: Il commercio dei paesi europei e URSS orientale è caratterizzato da una fondamentale asimmetria . Da una parte , vi è commercio intra-area ( intra - COMECON) che costituisce la parte prevalente ma è tuttavia meno importante per la crescita . D' altra parte, vi è il commercio con i paesi industrializzati ( est-ovest ), che , anche se rappresenta una porzione più piccola , attraverso l'importazione di manufatti ad alto contenuto tecnologico , è fondamentale per il processo di accumulazione interna . Il presente lavoro analizza il commercio le due aree negli ultimi dieci anni . L'autore esamina le principali caratteristiche del commercio intra - Comecon , il commercio est-ovest , le riforme del commercio estero e il problema della convertibilità delle valute in Unione Sovietica . The trade of Eastern European and USSR countries is characterised by a fundamental asymmetry. On the one hand, there is intra-area trade (intra-COMECON) which constitutes the prevalent part but is, however, less important for growth. On the other hand, there is trade with industrialised countries (east-west) which, although it represents a smaller portion, through the importation of highly technological manufactured goods, is crucial to the process of internal accumulation. The present work analyses the trade to the two areas over the past decade. The author looks at the principal characteristics of intra-COMECON trade, east-west trade, foreign trade reforms and the problem of currency convertibility in the Soviet Union. JEL: F14, P23

description: We investigate the influence of a weakly nonlinear Josephson bath consisting of a chain of Josephson junctions on the dynamics of a small quantum system (LC oscillator). Focusing on the regime where the charging energy is the largest energy scale, we perturbatively calculate the correlation function of the Josephson bath to the leading order in the Josephson energy divided by the charging energy while keeping the cosine potential exactly. When the variation of the charging energy along the chain ensures fast decay of the bath correlation function, the dynamics of the LC oscillator that is weakly and capacitively coupled to the Josephson bath can be solved through the Markovian master equation. We establish a duality relation for the Josephson bath between the regimes of large charging and Josephson energies respectively. The results can be applied to cases where the charging energy either is nonuniformly engineered or disordered in the chain. Furthermore, we find that the Josephson bath may become non-Markovian when the temperature is increased beyond the zero-temperature limit in that the bath correlation function gets shifted by a constant and does not decay with time.

description: We analyze the quantum-to-classical transition (QCT) for coupled bipartite quantum systems for which the position of one of the two subsystems is continuously monitored. We obtain the surprising result that the QCT can emerge concomitantly with the presence of highly entangled states in the bipartite system. Furthermore the changing degree of entanglement is associated with the back-action of the measurement on the system and is itself an indicator of the QCT. Our analysis elucidates the role of entanglement in von Neumann's paradigm of quantum measurements comprised of a system and a monitored measurement apparatus.

description: Die photokatalytische Reaktion von Methanol auf der (101) Oberfläche von TiO2 Anatas wurde mittels Rastertunnelmikroskopie (STM), Temperatur-programmierter Desorption (TPD) und Röntgenphotoelektronenspektroskopie (XPS) untersucht. Bei einer niedrigen Oberflächenbedeckung zeigt Methanol keine photokatalytische Aktivität. Bei einer höheren Oberflächenbedeckung wurde Methylformiat als Produkt erhalten. Methoxy wurde von uns mittels einer Reaktion von Methanol und entweder vordosiertem Sauerstoff oder Hydroxygruppen erzeugt. Durch die Kombination von TPD und STM konnten wir Formaldehyd und Methanol als Reaktionsprodukte von UV bestrahltem Methoxy identifizieren. Letzteres Produkt deutet auf eine Rückreaktion von Methoxy zu Methanol hin.
description: The photocatalytic reaction of methanol on the TiO2 anatase (101) surface was studied under UV irradiation by means of scanning tunneling microscopy (STM), temperature programmed desorption (TPD) and X-ray photoelectron spectroscopy (XPS). While low coverages of pure methanol showed no photocatalytic activity, at higher coverages methyl formate appeared as a secondary product. We created methoxy via a reaction of methanol with either predosed oxygen or terminal OH-groups. From the combination of TPD and STM measurements, we successfully identified formaldehyde and methanol as a secondary product of UV irradiated methoxy. The latter product suggests a reverse reaction from methoxy back to methanol.

description: Sternhaufen sind aktive Zentren der Sternentstehung, wobei Annäherungen zwischen jungen Einzelsternen häufig stattfinden. Findet eine solche Annäherung zwischen Partnern statt, bei denen einer über eine Akkretionsscheibe verfügt, die gravitationelle Instabilitäten aufweist, so können Fragmente, welche sich in der Scheibe gebildet haben, dieser entrissen werden. Dies stellt einen möglichen Mechanismus zur Enstehung ungebundener brauner Zwerge und Riesenplaneten dar. Die Diplomarbeit untersucht dieses Szenario unter Verwendung eines an der Universität Wien entwickelten Computerprogramms für hydrodynamische Simulationen. Es zeigte sich, dass in Begegnungen mit prograden Orbits häufig Fragmente aus der Scheibe herausgeschleudert werden, oder in durch Gezeitenkräfte verursachten Spiralarmen entstehen und dann das System verlassen. Bei retrograden Orbits ist das Herausschleudern von Fragmenten unwahrscheinlich. Zusätzlich wurde in einer Simulation ein FU Orionis-Ausbruch beobachtet, der von einem Fragment, das auf den Stern im Zentrum der Scheibe geschleudert wurde, verursacht wurde.
description: Stars often form in dense cluster environments, in which encounters between young stars are likely. If such an encounter happens while one of the stars has an extended disk that is gravitationally unstable, fragments formed within the disk can be ejected via multi-body gravitational interaction. This might be a formation mechanism for free-floating brown dwarfs and giant planets. The thesis examines the viability of this scenario with the hydrodynamics code developed at the University of Vienna. It was found that the ejection of fragments, both of fragments formed in the disk before the encounter and of fragments formed in tidal tails during the encounter, is very likely in prograde encounters, but unlikely in retrograde encounters. In addition, in one of the simulations an FU Orionis-like outburst was observed when a fragment was accelerated onto the disk central star.

description: Hybrid quantum systems, which combines the advantages of different quantum systems, play an essential role in the realisation of quantum computation, especially as quantum memory. This thesis discusses the very promising hybrid quantum system based on the ensemble of negatively charged nitrogen-vacancy centers (NV-centers) in diamond and superconducting microwave cavities. The decoherence of this system, due to the inhomogeneous spin broadening, seems to be the major obstacle of utilising the NV-centers as a quantum information storage. This works focuses on the study of the dynamics of our NV-center spin ensemble strongly coupled to a superconducting resonator driven by pulse sequences with a carrier frequency equaling the cavity frequency. A precise knowledge of the spin broadening, which has a non-Lorentzian distribution, led to the observation of the so called 'cavity protection effect'. Furthermore this work demonstrates the enhancement of the damped Rabi oscillations between the spin ensemble and the cavity mode through appropriate chosing of the microwave pulses, which could change in the order of two magnitudes. Last we also confirmed the theoretical analysis of the crossover from markovian to non-markovian dynamics for our system, which is achieved for increasing coupling strength.
Local responses to globalization : a comparative study of four North American universities' study abroad programs

description: Globalization has become an important concept in social science studies and its many facets intensely influence our current economic, cultural, and political spheres. Many within the higher education realm believe that globalization is a converging force imposing itself on higher education institutions. However, some scholars believe globalization could also become a force to recover universities' local characteristics. In a university context, study abroad programs are viewed as an important component of international activities on campus and have been increasingly advocated as a way to provide students with the knowledge and skills required for individuals and nation-states to compete in a global market—a direct linkage to globalization. On the other hand, study abroad programs are also bound in their specific local contexts and history. So, how do globalization and universities' local contexts influence these study abroad programs? This thesis is a comparative case study focusing on four North American universities' study abroad programs. The project investigates why and how these programs are organized at the university level within the context of globalization and explores how the local and the global interplay to shape the arrangement of study abroad programs in universities. The results of this study demonstrate that globalization forces some universities to be strategic players emphasizing internationalization as a direct response. In turn, such emphasis on internationalization enhances the development of study abroad programs in these universities. The desire to present students with the opportunities for developing cross-cultural communication skills also contributes to the development of study abroad programs. Yet the many facets of globalization also present challenges to study abroad programs. From influences of the economic aspect of globalization, the market ideology is creeping into the organizing process, raising the risk of losing these programs' long-term educational integrity to satisfy customer's needs. As travel costs make these programs more expensive, study abroad programs have to compete with other more cost-effective on-campus international activities for increasingly limited resources. From the perspective of a cultural version of globalization, the moving of people and ideas creates spaces for cultural exchange, and thus, adds the agenda of expanding certain ideological influences in some universities' study abroad programs. All these issues create a complex reality for the development of study abroad programs on university campuses. Further research on how the internationalization process influences the development of study abroad programs is needed to expand our understanding of impacts of economic globalization.

description: Dentin phosphoprotein (DPP) is a protein expressed mainly in dentin and to a lesser extent in bone. DPP has a disordered structure, rich in glutamic acid, aspartic acid and phosphorylated serine/threonine residues. It has a high capacity for binding to calcium ions and to hydroxyapatite (HA) crystal surfaces. We used molecular dynamics (MD) simulations as a method for virtually screening interactions between DPP motifs and HA. The goal was to determine which motifs are absorbed to HA surfaces. For these simulations, we considered five peptides from the human DPP sequence. All-atom MD simulations were performed using GROMACS, the peptides were oriented parallel to the {100} HA crystal surface, the distance between the HA and the peptide was 3 nm. The system was simulated for 20 ns. Preliminary results show that for the unphosphorylated peptides, the acidic amino acids present an electrostatic attraction where their side chains are oriented towards HA. This attraction, however, is slow to facilitate bulk transport to the crystal surface. On the other hand, the phosphorylated (PP) peptides are rapidly absorbed on the surface of the HA with their centers of mass closer to the HA surface. More importantly, the root mean square fluctuation (RMSF) indicates that the average structures of the phosphorylated peptides are very inflexible and elongate, while that of the unphosphorylated peptides are flexible. Radius of gyration (Rg) analysis showed the compactness of un-phosphorylated peptides is lower than phosphorylated peptides. Phosphorylation of the DPP peptides is necessary for binding to HA surfaces.

description: Odontoblast differentiation during physiological and reparative dentinogenesis is dependent upon multiple signaling molecules, including fibroblast growth factors (FGFs), bone morphogenetic proteins (BMPs) and Wingless/Integrated (Wnt) ligands. Recent studies in our laboratory showed that continuous exposure of primary dental pulp cultures to FGF2 exerted biphasic effects on the expression of markers of dentinogenesis. In the present study, we examined the possible involvement of the BMP and Wnt signaling pathways in mediating the effects of FGF2 on dental pulp cells. Our results showed that stimulatory effects of FGF2 on dentinogenesis during the proliferation phase of growth were associated with increased expression of the components of the BMP (Bmp2, Dlx5, Msx2, Osx) and Wnt (Wnt10a, Wisp2) pathways, and decreased expression of an inhibitor of the Wnt signaling, Nkd2. Further addition of FGF2 during the differentiation/mineralization phase of growth resulted in decreased expression of components of the BMP signaling (Bmp2, Runx2, Osx) and increased expression of inhibitors of the Wnt signaling (Nkd2, Dkk3). This suggests that both BMP and Wnt pathways may be involved in mediating the effects of FGF2 on dental pulp cells.

description: We compute the one-loop string corrections to the Wilson loop, glueball Regge trajectory and stringy hadron masses in the Witten model of non supersymmetric, large-N Yang-Mills theory. The classical string configurations corresponding to the above field theory objects are respectively: open straight strings, folded closed spinning strings, and strings orbiting in the internal part of the supergravity background. For the rectangular Wilson loop we show that besides the standard Luescher term, string corrections provide a rescaling of the field theory string tension. The one-loop corrections to the linear glueball Regge trajectories render them nonlinear with a positive intercept, as in the experimental soft Pomeron trajectory. Strings orbiting in the internal space predict a spectrum of hadronic-like states charged under global flavor symmetries which falls in the same universality class of other confining models.

description: Osteogenesis imperfecta is a congenital disease commonly characterized by brittle bones and caused by mutations in the genes encoding Type I collagen, the single most abundant protein produced by the body. The oim model has a natural collagen mutation, converting its heterotrimeric structure (two α1 and one α2 chains) into α1 homotrimers. This mutation in collagen may impact formation of the mineral, creating a brittle bone phenotype in animals. Femurs from male wild type (WT) and homozygous (oim/oim) mice, all at 12 weeks of age, were assessed using assays at multiple length scales with minimal sample processing to ensure a near-physiological state. Atomic force microscopy (AFM) demonstrated detectable differences in the organization of collagen at the nanoscale that may partially contribute to alterations in material and structural behavior obtained through mechanical testing and reference point indentation (RPI). Changes in geometric and chemical structure obtained from µ-Computed Tomography and Raman spectroscopy indicate a smaller bone with reduced trabecular architecture and altered chemical composition. Decreased tissue material properties in oim/oim mice are likely driven by changes in collagen fibril structure, decreasing space available for mineral nucleation and growth, as supported by a reduction in mineral crystallinity. Multi-scale analyses of this nature offer much in assessing how molecular changes compound to create a degraded, brittle bone phenotype.

description: Cell instructive mineralized biomaterials are a promising alternative to conventional auto-, allo-, and xenograft therapies for the reconstruction of critical sized defects. Extracellular matrix proteins, peptide domains, and functional motifs demonstrating cell and mineral binding activity have been used to improve cell attachment. However, these strategies vary in their tissue regeneration outcomes due to lack of specificity to both regenerative cell populations and the material substrates. In order to mediate cell-specific interactions on apatite surfaces, we identified peptide sequences with high affinity towards apatite (VTKHLNQISQSY, VTK) and clonally derived human bone marrow stromal cells (DPIYALSWSGMA, DPI) using phage display. The primary aims of this study were to measure apatite binding affinity, human bone marrow stromal cell (hBMSC) adhesion strength, and peptide specificity to hBMSCs when the apatite and cell-specific peptides are combined into a dual-functioning peptide. To assess binding affinity to hydroxyapatite (HA), binding isotherms were constructed and peptide binding affinity (K1) determined. HBMSC, MC3T3 and mouse dermal fibroblast (MDF) adhesion strength on biomimetic apatite functionalized with single- and dual-functioning peptide sequences were evaluated using a centrifugation assay. DPI-VTK had the highest binding strength towards hBMSCs (p p

description: The European Union is nearly entirely dependent on imports of phosphorus for its food production, yet there are high losses and wastes in the food commodity chain. There is currently no direct P Regulation or Directive at EU level that would make EU countries liable to its application. This results in unsustainable P practices in the EU leading to environmental and resource related challenges. Based on previous Phosphorus Flow Analysis, the management of the European Union's phosphorus flows; processes and stocks will be investigated (Phosphorus import into EU; soil, waste management and hydrosphere). The European phosphorus balance will be analysed and presented by STAN, to quantify the losses of phosphorus in the EU15 P cycle. The main goal and novel part of this thesis is the analysis of current P policies at EU level and the introduction of EU policy recommendations for future EU P policy. Current and potential future European policies addressing the flow "P imports" and the three processes "hydrosphere", "soil" and "waste management" will be analysed, determining how effective current P policy is in tackling challenges regarding environmental protection and resource availability in the EU. According to the analysis of the EU P Balance, the over application of P on EU soils pose the greatest environmental challenges. In order to overcome the current unsustainable use of P, the EU must firstly implement agricultural policy directed at the use of P at farm level, based on contemporary farming technologies. Subsequently, the application of agricultural policy, as estimated in Figure 1, will have the greatest effect on the hydrosphere and import of P. The recommended policies for the flow "import" and the three processes "soil", "waste management" and "hydrosphere" are estimated to reduce 45% of excess P import to the EU.

description: After years of holding back due to an instable economic outlook, merger and acquisition (M&A) transactions have significantly increased in the US in the years 2013 and 2014. An important part of the M&A process is the due diligence phase. Today, the focus of the due diligence process still lies on commercial, financial, and tax issues. Technical due diligence focuses on the evaluation of the produced product and on machinery investment. Only a minor part of the due diligence process consists of evaluating the underlying technologies and the potential to be used for other products or business cases. If a product has low technical complexity and requirements, this approach can be accepted. In case of a high-tech product, however, neglecting a holistic evaluation of a technology can result in an entirely wrong company value. As a first step it is analyzed what the typical process steps in an M&A process are. Different domains of due diligences are introduced and it is indicated where technology is influencing. Interfaces and requirements to the technology evaluation out of the other due diligence domains are indicated and discussed. Most common technology evaluation methods are introduced. A general indication is given about the possible use in an M&A process. Those methods are opposed to the requirement in a technical due diligence and rated about the fulfillment of these requirements. The best suitable methods are combined in a holistic model. A model is developed and explained to evaluate technologies of a company. As a major result of the model, it indicates the premium or discount price, which needs to be taken into account for an offer. The model is based on the most important evaluation criteria for technology in an M&A process and allows to rate each criteria by a monetary value in order to oppose a potential gap with the costs that would occur to close this gap. Modell developed is applied in an M&A business case. Conclusions from the application of the evaluation model, pros and cons are discussed and suggestions for future research work are made. 2. Research Questions: What are process steps in an MA undertaking and how technology need to be taken into account? What are typical interfaces of technology evaluation to other domains in the due diligence phases of an MA process? What are requirements for a technology evaluation in an M&A process? How are technology evaluation methods meeting the requirements in a technical due diligence of an M&A processes? How can those methods be applied and combined in a holistic technology evaluation model? What are criteria for a technology evaluation in an M&A process and how can they be evaluated in monetary values?

description: We propose topological semimetals generated by the square-root operation for tight-binding models in two and three dimensions, which we call square-root topological semimetals. The square-root topological semimetals host topological band touching at finite energies, whose topological protection is inherited from the squared Hamiltonian. Such a topological character is also reflected in emergence of boundary modes with finite energies. Specifically, focusing on topological properties of squared Hamiltonian in class AIII, we reveal that a decorated honeycomb (decorated diamond) model hosts finite-energy Dirac cones (nodal lines). We also propose a realization of a square-root topological semimetal in a spring-mass model, where robustness of finite-energy Dirac points against the change of tension is elucidated.

description: Essential protein plays a crucial role in the process of cell life. The identification of essential proteins can not only promote the development of drug target technology, but also contribute to the mechanism of biological evolution. There are plenty of scholars who pay attention to discovering essential proteins according to the topological structure of protein network and biological information. The accuracy of protein recognition still demands to be improved. In this paper, we propose a method which integrate the clustering coefficient in protein complexes and topological properties to determine the essentiality of proteins. First, we give the definition of In-clustering coefficient (IC) to describe the properties of protein complexes. Then we propose a new method, complex edge and node clustering coefficient (CENC) to identify essential proteins. Different Protein-Protein Interaction (PPI) networks of Saccharomyces cerevisiae, MIPS and DIP are used as experimental materials. Through some experiments of logistic regression model, the results show that the method of CENC can promote the ability of recognizing essential proteins, by comparing with the existing methods DC, BC, EC, SC, LAC, NC and the recent method UC.

description: In neglected communities, waste and organic residues are not only a vector of several problems, like diseases and water pollution, but also a contributor to increasing forms of vulnerability and marginalization. At the same time, these communities also have presented innovative local initiatives and transformative learning about natural resources management that can be a vehicle for achieving more sustainable food systems. In the south of Brazil, community-based organic residue management has shown an extraordinary potential to improve food security and livelihoods for (≈1600) community members of a vulnerable urban territory. In this context, the overall objective of this article is (a) To better understand what Social Learning (SL) processes related to successful organic residues management in neglected communities exist and (b) To identify what knowledge systems are created in one empirical case. The study case is based on a communitarian waste management project, the Bucket Revolution Project (BRP). The analytical framework builds upon social learning theory and its triple-loop process focusing on four specific phenomena. The applied mixed-methods approach was made in four steps: 1. a focus group to investigate collective community issues; 2. semi-structured interviews to investigate specific and individual issues in the context of the BRP; 3. social media analysis to better understand the BRP narratives; and finally 4. participant observation in community and institutional meetings. Mainly using MaxQda software and coding indicators of SL, the data show that “Diversity of knowledge integration” is the most identified SL indicator in the interviews (52%). For BRP, identity development, community conditions improvement, and environment understanding are three key components of the knowledge system enhanced through an underlying process of social learning. Furthermore, the study also shows that there are endogenous and exogenous social learning processes at work.

Several economists have suggested that such a measure is a duplication devoid of real effects because, given the demand for such bonds, the State would be forced to increase the gross interest payment by exactly the same amount it collects by raising the tax rate. By contrast, the author claims that such a measure would provide a net cash benefit for the public finances. JEL Codes: E43, H21, H63

description: Western countries over the past few decades have experimented with very different and often negative levels of real interest rates. With the change in monetary policy inaugurated by the United States in the early eighties began a period characterised by high real interest rates. This paper analyses the relationship between public debt and interest rates in Italy based on alternative assumptions. The author shows how the adjustment of the economy to changes in monetary policy has ended up creating a united front in defence of financial income, which includes households, businesses and banks. She concludes that the level of the interest rate that tends to prevail in the market can not be explained with the theoretical model based on the equilibrium of supply and demand of loanable funds determined by the Walrasian equilibrium.

description: Direct measurement of a bulk topological observable in topological phase of matter has been a long-standing issue. Recently, detection of bulk topology through quench dynamics has attracted growing interests. Here, we propose that topological characters of a quantum quadrupole insulator can be read out by quench dynamics. Specifically, we introduce a quantity, a quadrupole moment weighted by the eigenvalues of the chiral operator, which takes zero for the trivial phase and finite for the quadrupolar topological phase. By utilizing an efficient numerical method to track the unitary time evolution, we elucidate that the quantity we propose indeed serves as an indicator of topological character for both noninteracting and interacting cases. The robustness against disorders is also demonstrated.

description: Agroforestry systems (AFS) are proved to enhance sustainable land management. Thus, there is increasing demand for effective ways to scale up AFS so that more people can benefit. Consequently, this study assesses the scaling-up potential of agroforestry systems (AFS) using cacao farming and cattle ranching in Caquetá and Cesar, Colombia, as examples. An ex-ante assessment using the ScalA tool is conducted through interviews with AFS experts from institutions promoting AFS. Using a comparative approach, results reveal that AFS have different scaling-up potential depending on the type of farming system and location characteristics. In our case, it is slightly higher for cacao farming than for cattle ranching in both regions and it is higher in Caquetá than in Cesar for both systems. Factors hindering the scaling-up potential for both regions are economic conditions at the local and regional levels since there is a lack of stable and differentiated markets to absorb AFS products. In contrast, the scaling-up potential in both regions is increased by the factors related to the capacity of the organizations that promote AFS and the attitudes of local communities toward them. The study generates information about factors that may hinder or foster AFS scaling-up, including not just the capacities and mechanisms to promote them but also the enabling conditions. This contributes to prioritizing AFS interventions and better allocating their resources to increase their chances of successful scaling-up.

description: We survey the equations of continuous-time quantum walks on simple one-dimensional lattices, which include the finite and infinite lines and the finite cycle, and compare them with the classical continuous-time Markov chains. The focus of our expository article is on analyzing these processes using the Laplace transform on the stochastic recurrences. The resulting time evolution equations, classical versus quantum, are strikingly similar in form, although dissimilar in behavior. We also provide comparisons with analyses performed using spectral methods.

description: In this paper we prove an analogue in the discrete setting of \Bbb Z^d, of the spherical maximal theorem for \Bbb R^d. The methods used are two-fold: the application of certain "sampling" techniques, and ideas arising in the study of the number of representations of an integer as a sum of d squares in particular, the "circle method". The results we obtained are by necessity limited to d \ge 5, and moreover the range of p for the L^p estimates differs from its analogue in \Bbb R^d.

description: Diese Diplomarbeit zählt zu einer Reihe von Arbeiten, die sich mit der virtuellen Rekonstruktion von komplett oder teilweise zerstörten Synagogen anhand mangelhafter Unterlagen beschäftigen. Der Standort des hier behandelten Gebäudes war Mistelbach in Niederösterreich. Obwohl diese im Februar 1896 eingeweihte Synagoge erst 1979 abgerissen worden ist, gibt es so gut wie kein Planmaterial darüber. Diese Diplomarbeit beschäftigt sich deshalb unter anderem damit, Grundrisse, Schnitte und Ansichten aus Fotos und Katasterplan zu erarbeiten. Das abschließende ArchiCAD-Modell und die finale Artlantis-Visualisierung wurden in diesem Fall durch Konvertierung aus einem 3ds-Max-Modell erzeugt, welches zuvor anhand der eigens erstellten Pläne modelliert wurde.
description: This thesis counts to a number of works focused on the virtual reconstruction of completely or partially destroyed synagogues based on insufficient information. In this case, the building stood in Mistelbach in lower Austria. Although this synagogue, which was inaugurated in February 1896, was not destroyed until 1979, there is almost no documentation about it available. This thesis therefore recreates floor plans, sections and elevations from photos and the existing land register plans. The concluding ArchiCAD-model and final Artlantis-visualisation was produced through converting a 3ds-Max-model which was built from the before mentioned plans.
Un percorso tra i temi della nuova macroeconomia keynesiana

description: For almost twenty years a large part of the theoretical work of Keynesian economists has been dedicated to the research of "theoretical justifications" for the propositions of non-neutrality and, more generally, for the interpretation of unemployment as a phenomenon related to disequilibrium. The present work discusses in particular the neo-Keynesian literature that has studied the rigidities of the price system and the resulting frictions in the adjustment towards neoclassical equilibrium. Rather than a systematic review, the work provides an illustration of the key ideas behind this line of research. Moreover, it provides an outline of some possible intellectual paths among the various "neo-Keynesian" responses to the neoclassical challenge of the 1970s. The author concludes by presenting some possible connections between the theoretical insights of the various analytical strands that are considered. JEL Codes: E12

description: How can we relate the constraint structure and constraint dynamics of the general gauge theory in the Hamiltonian formulation with specific features of the theory in the Lagrangian formulation, especially relate the constraint structure with the gauge transformation structure of the Lagrangian action? How can we construct the general expression for the gauge charge if the constraint structure in the Hamiltonian formulation is known? Whether can we identify the physical functions defined as commuting with first-class constraints in the Hamiltonian formulation and the physical functions defined as gauge invariant functions in the Lagrangian formulation? The aim of the present article is to consider the general quadratic gauge theory and to answer the above questions for such a theory in terms of strict assertions. To fulfill such a program, we demonstrate the existence of the so-called superspecial phase-space variables in terms of which the quadratic Hamiltonian action takes a simple canonical form. On the basis of such a representation, we analyze a functional arbitrariness in the solutions of the equations of motion of the quadratic gauge theory and derive the general structure of symmetries by analyzing a symmetry equation. We then use these results to identify the two definitions of physical functions and thus prove the Dirac conjecture.
