Effect of 2-Substitution on the Rearrangement of 1-Cyclopropylvinyl Cations

2-Substitution in 1-cyclopropylvinyl cations produces a steric effect on cation generation and solvent trapping, but an electronic charge-stabilizing effect on cyclopropyl-to-cyclobutyl rearrangement

Bank procyclicality, credit crunches, and asymmetric monetary policy effects: a unifying model

Much concern has recently been expressed that both large, procyclical changes in bank assets and "credit crunches" caused by bank reluctance to expand loans during recessions contribute to economic instability. These effects are difficult to explain using the standard textbook model of deposit expansion in which deposits are constrained only by reserve requirements. However, these effects follow easily if the model is expanded to include a second, capital constraint.Bank assets ; Monetary policy

Barrier island erosion and overwash study -- effect of seawalls. Volume 2

This is the second of a pair of reports documenting the effects of storms on beach systems including the presence of seawalls. With the aim of simulating the effects of overwash on barrier islands with seawalls and characterizing their response, a series of eight experiments was conducted at the Coastal Engineering Laboratory of the University of Florida. The barrier island was simulated by a 400 feet wide horizontal crest and an initially uniform mildly-sloped (1:19) beach. The effects of positioning the seawall at two different locations as well as the effects of various storm surge levels and accompanying overtopping were investigated. Experiments were conducted with both regular and irregular storm waves. With the seawall located at the slope break between the crest and the sloping beach of the barrier island, and the crest of the seawall just submerged in sand, the effects on the sediment transport process were found to be minimal. For the same position of the seawall but with the crest of the seawall raised above the surrounding ground level, overtopping caused washover of sand indicating substantial transport in suspension. Increased levels of overtopping tended to accentuate bed profile changes but supress bar formation (as did irregular waves). Positioning the seawall at the Mean Sea Level shoreline caused significant scour both immediately landward as well as immediately seaward of the seawall. A prominent scour trough developed further seaward. The longshore bar was highly three-dimensional. It appears that seawalls need to be located adequately landward of the shoreline to discharge their function effectively without adverse effect to the beach. In addition, concerns for safety warrant the presence of an adequate buffer-zone between the seawall and the upland property. (61 pp.

Coherent states in fermionic Fock-Krein spaces and their amplitudes

We generalize the fermionic coherent states to the case of Fock-Krein spaces, i.e., Fock spaces with an idefinite inner product of Krein type. This allows for their application in topological or functorial quantum field theory and more specifically in general boundary quantum field theory. In this context we derive a universal formula for the amplitude of a coherent state in linear field theory on an arbitrary manifold with boundary.Comment: 20 pages, LaTeX + AMS + svmult (included), contribution to the proceedings of the conference "Coherent States and their Applications: A Contemporary Panorama" (Marseille, 2016); v2: minor corrections and added axioms from arXiv:1208.503

Bank privatization in Argentina : a model of political constraints and differential outcomes

Based on results from country case studies, many researchers have claimed that political constraints affect bank privatization transactions, which in turn affect the post-privatization performance of the banking sector. But no study has either econometrically tested how political constraints affect bank privatization transactions or theretically modeled the privatization transaction. The authors present a simple theoretical framework that models the inherent tradeoffs faced by governments and potential buyers in privatization transactions involving banks. The potential buyer is concerned about the probability that the bank will remain solvent, about the profits it will earn after privatization, and about the price paid for the assets and liabilities. The government is concerned about the price received for the assets, about layoffs, and about service coverage after privatization. The evidence from bank privatization transactions in Argentina in the 1990s supports several of their theoretical predictions. In particular, provinces with highfiscal deficits were willing to accept layoffs and to guarantee a larger part of the privatized banks'portfolio in return for a higher price. The tequila crisis (Mexico's economic crisis in 1994-95) meant that politicians could protect fewer jobs and had to assume a greater share of their public banks'assets. Evidence of better performance at banks privatized after Mexico's crisis suggests that, by tying politicians'hands, the crisis may have brought unforeseen benefits. This conjecture awaits further empirical validation, but the authors hope that by explicitly incorporating the incentives politicians face, analysis can begin to address the question of why some privatizations succeed more than others.Economic Theory&Research,International Terrorism&Counterterrorism,Banks&Banking Reform,Municipal Financial Management,Financial Crisis Management&Restructuring,Banks&Banking Reform,Municipal Financial Management,Economic Theory&Research,Financial Crisis Management&Restructuring,International Terrorism&Counterterrorism

Seamless metal-clad fiber-reinforced organic matrix composite structures and process for their manufacture

A metallic outer sleeve is provided which is capable of enveloping a hollow metallic inner member having continuous reinforcing fibers attached to the distal end thereof. The inner member is then introduced into outer sleeve until inner member is completely enveloped by outer sleeve. A liquid matrix member is then injected into space between inner member and outer sleeve. A pressurized heat transfer medium is flowed through the inside of inner member, thereby forming a fiber reinforced matrix composite material. The wall thicknesses of both inner member and outer sleeve are then reduced to the appropriate size by chemical etching, to adjust the thermal expansion coefficient of the metal-clad composite structure to the desired value. thereby forming a fiber reinforced matrix composite material. The wall thicknesses of both inner member and outer sleeve are then reduced to the appropriate size by chemical etching, to adjust the thermal expansion coefficient of the metal-clad composite structure to the desired value. The novelty of this invention resides in the development of a efficient method of producing seamless metal clad fiber reinforced organic matrix composite structures

Marketing in 1985: A View from the Ivory Tower: How will the business environment of 1985 affect competitive marketing strategy?

Inflation and recession, resource shortages, a web of ecological problems, changing social values, a proliferation of business regulations, and other developments of recent years have taken their toll on American business. Such changes in the external environment of business have stimulated academicians and writers for the general media to address questions such as: Can Capitalism Survive: ; Can Marketing Survive? ; Will Shortages Bankrupt the Marketing Concept? Others are directing their efforts to forecasting the uncertain future and the burgeoning discipline of futures research. This article reports on the application of one futures research technique-the solicitation of expert opinion-to the field of marketing. Its purpose is to examine the major dimensions of the future of marketing as seen by marketing education leaders

Long-range beam-beam experiments in the relativistic heavy ion collider

Long-range beam-beam effects are a potential limit to the LHC performance with the nominal design parameters, and certain upgrade scenarios under discussion. To mitigate long-range effects, current carrying wires parallel to the beam were proposed and space is reserved in the LHC for such wires. Two current carrying wires were installed in RHIC to study the effect of strong long-range beam-beam effects in a collider, as well as test the compensation of a single long-range interaction. The experimental data were used to benchmark simulations. We summarize this work.Comment: 12 pages, contribution to the ICFA Mini-Workshop on Beam-Beam Effects in Hadron Colliders, CERN, Geneva, Switzerland, 18-22 Mar 201
