Transfer Problem Dynamics: Macroeconomics of the Franco-Prussian War Indemnity

We study the classic transfer problem of predicting the effects of an international transfer on the terms of trade and the current account. A two-country model with debt and capital allows for realistic features of historical transfers: they follow wartime increases in government spending and are financed partly by borrowing. The model is applied to the largest historical transfer, the Franco-Prussian War indemnity of 1871-1873. In these three years, France transferred to Germany an amount equal to 22 percent of a year's GDP. When the transfer is combined with measured shocks to fiscal policy and a proxy for productivity shocks over the period, the model provides a very close fit to the historical sample paths of French GDP, terms of trade, net exports, and aggregate consumption. This makes a strong case for the dynamic general equilibrium approach to studying the transfer problem.transfer problem, current account, terms of trade

Superpositions of the Orbital Angular Momentum for Applications in Quantum Experiments

Two different experimental techniques for preparation and analyzing superpositions of the Gaussian and Laguerre-Gassian modes are presented. This is done exploiting an interferometric method on the one hand and using computer generated holograms on the other hand. It is shown that by shifting the hologram with respect to an incoming Gaussian beam different superpositions of the Gaussian and the Laguerre-Gaussian beam can be produced. An analytical expression between the relative phase and the amplitudes of the modes and the displacement of the hologram is given. The application of such orbital angular momenta superpositions in quantum experiments such as quantum cryptography is discussed.Comment: 18 pages, 4 figures. to appear in Journal of Optics

A Theory of Industry Level Activity for Understanding the Adoption of Interorganizational Systems

Increasingly we wish to ask and research questions about the adoption of interorganizational systems and electronic commerce at the industry level but are hampered by the lack of a theory of concerted purposeful action at this large level of analysis. In this paper we give the outlines of such a theory and indicate the uses to which it can be put. Particular attention is paid to how the routine day-to-day activities of the firms and support organizations that make up an industry group can be coordinated in such a way that we can speak of an industry as engaged in purposeful activity. We contend that only through a deep understanding of the possibilities and nature of routine coordinated activity at this level can issues concerning promotion, implementation and adoption of interorganizational systems by whole industries be properly framed

Developing an Understanding of Interorganizational Systems: Arguments for Multi Level Analysis and Structuration Theory

Strategies and policies for the adoption and development of interorganizational systems require further understanding of the theoretical background to these systems. An argument is made for development of theory that is multi-level, processual and has an emergent perspective. Such theory is needed to deal with a context where environmental influences are important in addition to complex interactions between organizational activities at the micro-level and industry structure at the macro-level. The use of structuration theory as a vehicle to advance further understanding is explored. An illustration is given of application of this theory in the development of supply chain management in the beef industry

Electrodynamic coupling of electric dipole emitters to a fluctuating mode density within a nano-cavity

We investigate the impact of rotational diffusion on the electrodynamic coupling of fluorescent dye molecules (oscillating electric dipoles) to a tunable planar metallic nanocavity. Fast rotational diffusion of the molecules leads to a rapidly fluctuating mode density of the electromagnetic field along the molecules' dipole axis, which significantly changes their coupling to the field as compared to the opposite limit of fixed dipole orientation. We derive a theoretical treatment of the problem and present experimental results for rhodamine 6G molecules in cavities filled with low and high viscosity liquids. The derived theory and presented experimental method is a powerful tool for determining absolute quantum yield values of fluorescence.Comment: 5 pages, 3 figures, accepted by Physical Review Letter

Transfer wiedzy i technologii z organizacji naukowo-badawczych do przedsiębiorstw

Rozwój innowacyjnej gospodarki zależy od umiejętności korzystania z osiągnięć nauki i możliwości ich dystrybucji. Książka wpisuje się w niezwykle istotną dyskusję dotyczącą poprawy innowacyjności polskiej gospodarki poprzez udoskonalenie współpracy pomiędzy sektorem nauki i biznesu. Autorzy diagnozują sytuację polskich uczelni w zakresie komercjalizacji wyników badań oraz współpracy z biznesem, badają różne grupy interesariuszy biorących udział w profesjonalnych procesach transferu wiedzy i technologii w Polsce, Norwegii, Francji, Czechach, na Węgrzech, a także w USA i Kanadzie. Analizują studia dobrych praktyk – zarówno polskich, jak i zagranicznych – aby na tej podstawie zaprezentować rekomendacje niezbędnych zmian dla uczelni w obszarze kształtowania dobrych relacji z przedsiębiorstwami w celu zwiększania potencjału innowacyjnego i zrostu konkurencyjności gospodarki

Targeting determinants of dosage compensation in Drosophila

The dosage compensation complex (DCC) in Drosophila melanogaster is responsible for up-regulating transcription from the single male X chromosome to equal the transcription from the two X chromosomes in females. Visualization of the DCC, a large ribonucleoprotein complex, on male larval polytene chromosomes reveals that the complex binds selectively to many interbands on the X chromosome. The targeting of the DCC is thought to be in part determined by DNA sequences that are enriched on the X. So far, lack of knowledge about DCC binding sites has prevented the identification of sequence determinants. Only three binding sites have been identified to date, but analysis of their DNA sequence did not allow the prediction of further binding sites. We have used chromatin immunoprecipitation to identify a number of new DCC binding fragments and characterized them in vivo by visualizing DCC binding to autosomal insertions of these fragments, and we have demonstrated that they possess a wide range of potential to recruit the DCC. By varying the in vivo concentration of the DCC, we provide evidence that this range of recruitment potential is due to differences in affinity of the complex to these sites. We were also able to establish that DCC binding to ectopic high-affinity sites can allow nearby low-affinity sites to recruit the complex. Using the sequences of the newly identified and previously characterized binding fragments, we have uncovered a number of short sequence motifs, which in combination may contribute to DCC recruitment. Our findings suggest that the DCC is recruited to the X via a number of binding sites of decreasing affinities, and that the presence of high-and moderate-affinity sites on the X may ensure that lower-affinity sites are occupied in a context-dependent manner. Our bioinformatics analysis suggests that DCC binding sites may be composed of variable combinations of degenerate motifs
