Information And Normal Backwardation As Determinants Of Trading Performance: Evidence From The North-Sea Oil Forward Market, Gordon M. Phillips, Robert J. Weiner
Information And Normal Backwardation As Determinants Of Trading Performance: Evidence From The North-Sea Oil Forward Market, Gordon M. Phillips, Robert J. Weiner
Purdue CIBER Working Papers
In this paper we take advantage of a unique micro-database on forward trading in the international petroleum market, with information on the buyer and seller in each transaction. We utilize transaction-specific data to test directly predictions from the theory of normal backwardation vs. information-based predictions of who profits in these markets. We find that no trader groups make significan profits on interday measures. Within the day, however, groups likely to have superior information do make significant profits. The results are not supportive of normal backwardation, but are consistent with the time pattern of information dissemination in this market--deals made during …

Industry And Country Effects On Manager's Perceptions Of Environmental Uncertainties, Kent D. Miller
Purdue CIBER Working Papers
International management research highlights political, government policy, and macroeconomic uncertainties. Strategy studeies focus on input supply, product market, and competitive uncertainties. This study develops and tests the reliability of an instrument for measuring managers' uncertainty perceptions. Data analyses using an international sample provide insights into the relative importance of country and industry factors for explaining managers' perceptions of different environmental uncertainties.
The Association Between The Level Of International Diversification And Risk, Stephen R. Goldberg, Frank L. Heflin
The Association Between The Level Of International Diversification And Risk, Stephen R. Goldberg, Frank L. Heflin
Purdue CIBER Working Papers
This study analyzes the association between the degree of international involvement (DOI) and risk. Both systematic risk (measured by the market model beta) and total rishk (measured by variance of return) are analyzed. Betas of fully diversified foreign stock portfolios are shown to be lower than betas of domestic portfolios. Therefore, if the beta of a foreign investment by a U.S. firm is equal to the average beta of an investment in the foreign market, then overall firm beta will deverase as DOI increases (hypothesis). While total risk might be decreased due to the diversification provided by increasing DOI, currency, …
Foreign Currency Translation Under Two Case-Integrated And Isolated Economies, Stephen R. Goldberg, Joseph H. Godwin
Foreign Currency Translation Under Two Case-Integrated And Isolated Economies, Stephen R. Goldberg, Joseph H. Godwin
Purdue CIBER Working Papers
Beaver and Wolfson (1982 BW) identify economic interpretability and symmetry as desirable properties for financial statement translation. They then analyze translation methods with respect to these properties assuming perfect and complete markets between and within both countries (referred to, here, as the integrated economics case). This study extends BW's analysis by examining isolated economics characterized by perfect and complete internal markets and a random relationship between prices and exchange rates. In BW's integrated economics case, inflation differentials drive exchange rate changes. No exchange rish exists, although monetary assets are exposed to the risk of unexpected inflation. Isolated economies expose monetary …
Penalties And Exclusion In The Rescheduling And Forgiveness Of International Loans, John A. Carlson, Aasim M. Husain, Jeffrey A. Zimmerman
Penalties And Exclusion In The Rescheduling And Forgiveness Of International Loans, John A. Carlson, Aasim M. Husain, Jeffrey A. Zimmerman
Purdue CIBER Working Papers
When a borrowing coutnry is reluctant to repay an international loan, the lender has few legal remedies but can impose penalty costs that harm the borrower rather than benefit the lender. If the lender can also temporarily exclude the borrower from new loans, the borrower with a sufficiently high time preference will agree to reschedule the loan. If the rescheduling condition is met, a contract which includes a contingency for partial forgiveness can be shown to dominate a contract without forgiveness.
Some Welfare Effects Of Dynamic Customs Union Formation, Jon D. Haveman
Some Welfare Effects Of Dynamic Customs Union Formation, Jon D. Haveman
Purdue CIBER Working Papers
This paper deals with an issue of increasing importance in a world where preferential trading arrangements are the call of the day: the effects on world welfare of sequential customs union foration. A computational model of customs union formation is developed and simulated under a variety of assumptions. These assumptions concern various characteristics of the world, the pattern of customs union formation, and GATT restrictions on the common external tariff imposed by the customs union. The results show that unrestricted customs union formation is likely to result in successive deterioration of world welfare, despite gains for the member countries collectively. …

Interposed Abdominal Compression Cardiopulmonary Resuscitation: Are We Missing The Mark In Clinical Trials?, Charles F. Babbs
Interposed Abdominal Compression Cardiopulmonary Resuscitation: Are We Missing The Mark In Clinical Trials?, Charles F. Babbs
Weldon School of Biomedical Engineering Faculty Publications
Straightforward considerations of abdominal anatomy in human beings set tight constraints on the theoretically optimal technique for abdominal compressions during interposed abdominal compression (IAC)-CPR. The location and extent of the abdominal aorta lead naturally to the recommendation that IAC be applied at a level corresponding to the lower two thirds of the sterno-umbilical line. The force vector required to achieve contact compression of the abdominal aorta is inclined in the transverse plane at an angle of 11 degrees from the vertical toward the left. Such slightly angled compression subjects the abdominal aorta to maximally flattening; while the inferior vena cava …
Meta-State Conversion, H. G. Dietz
Meta-State Conversion, H. G. Dietz
Department of Electrical and Computer Engineering Technical Reports
In MIMD (Multiple Instruction stream, Multiple Data stream) execution, each processor has its own state. Although these states are generally considered to be independent entities, it is also possible to view the set of processor states at a particular time as single, aggregate, "Meta State." Once a program has been converted into a single finite automaton based on Meta States, only a single proram counter is needed. Hence, it is possible to duplicate the MIMD execution using SIMD (Single Instruction stream, Multiple Data stream) hardware without the ovehead of interpretation or even of having each processing element keep a copy …
A Spectral Flux Method For Solving The Boltzmann Equation, Muhammad A. Alam, Mark A. Stettler, Mark S. Lundstrom
A Spectral Flux Method For Solving The Boltzmann Equation, Muhammad A. Alam, Mark A. Stettler, Mark S. Lundstrom
Department of Electrical and Computer Engineering Faculty Publications
A spectral method for solving the Boltzmann equation by the scattering matrix approach is presented, The algorithm discussed can be used to simulate both bulk and device properties with arbitrary field profiles. Although the primary goal is to reduce the data storage problem of the scattering matrix approach, many of the concepts and mathematical properties developed may be useful for other traditional spectral methods as well.

Concentration‐Dependent Optical‐Absorption Coefficient In N‐Type Gaas, Gregory Benedict Lush, H. F. Macmillan, S. Asher, Michael R. Melloch, Mark S. Lundstrom
Department of Electrical and Computer Engineering Faculty Publications
The doping-dependent, near-band-edge optical-absorption coefficient CY(h v) was deduced from optical transmission measurements in n-type GaAs thin films. The selenium-doped films were grown by metalorganic chemical-vapor deposition and do ed to produce room-temperature electron concentrations from 1.3 x 10” to 3.8X 1018 cm- P . The transmission measurements covered photon energies between 1.35 and 1.7 eV and were performed on double heterostructures with the substrate removed by selective etching. The results show good qualitative agreement with previous studies and good quantitative agreement, except for the heavily doped samples. For na=3.8 X 10” cme3, a( 1.42 eV> is approximately four times …

Department of Electrical and Computer Engineering Faculty Publications
The variation of minority electron mobility with doping density in p+-GaAs has been measured with the zero-field time-of-flight technique. The results from a series of nine GaAs films doped between 1 X lOI and 8 X 10” cmm3 show the mobility decreasing from 1950 cm2 V-’ s-l at 1 X 10” cmm3 to 1370 cm2 V-l s-l at 9X 10” cmB3. For the doping range 9 x 1018-8x 1019 cme3, the decreasing trend in mobility is reversed. The measured mobility of 3710 cm2 V-’ s-l at 8 X 10” cmp3 is about three times higher than the measured value at …
Compiler-Assisted Cache Coherence, Chiiwen Liou, Henry G. Dietz
Compiler-Assisted Cache Coherence, Chiiwen Liou, Henry G. Dietz
Department of Electrical and Computer Engineering Technical Reports
Although it is convenient to program multiprocessors as though all processors share access to the same memory, it is difficult to construct hardware directly implementing this model. Allowing each processor to have its own independent cache partially solves this problem; unfortunately, different caches might hold different values for the same main memory address. Making the cache hardware always be coherent - one value per address - makes the hardware expensive and slow. This paper proposes compiler analysis to generate explicit cache control instructions to ensure that all program memory accesses execute as though the caches were coherent. Compared to other …
