Some cases of Alzheimer's disease are inherited as an autosomal dominant trait. Genetic linkage studies have mapped a locus (AD3) associated with susceptibility to a very aggressive form of Alzheimer's disease to chromosome 14q24.3. We have defined a minimal cosegregating region containing the AD3 gene, and isolated at least 19 different transcripts encoded within this region. One of these transcripts (S182) corresponds to a novel gene whose product is predicted to contain multiple transmembrane domains and resembles an integral membrane protein. Five different missense mutations have been found that cosegregate with early-onset familial Alzheimer's disease. Because these changes occurred in conserved domains of this gene, and are not present in normal controls, they are likely to be causative of AD3.

Environmental Kuznets Curve Hypothesis: A Survey

This study examines the effect of the composition of federal and state government spending on various important air pollutants in the US using a newly assembled data set of government spending. The results indicate that a reallocation of spending from private goods (RME) to social and public goods (PME) by state and local governments reduces sulfur dioxide concentrations while the composition of federal spending has no effect. A 10% percent increase in the share of state and local social and public goods government spending reduces air pollution concentrations by 3 to 5% for Sulfur Dioxide, 2 to 3% for particulate matter 2.5 and 1 to 2 % for ozone. The results are robust to various sensitivity checks.

Government Spending and Air Pollution in the US

The development of the concept of flexible functional forms and its applications in the derivation of plausible functional forms for dual cost and profit functions in the early seventies [Diewert 1971; Christensen, Jorgensen and Lau] was an important step which led to the proliferation of empirical applications of duality. Several of these studies have concerned the agricultural sector. Of these, the study by Binswanger [1974a and 1974b] using U.S.A. data appears to be one of the earliest.

Applications of duality theory to agriculture

[1] In late October and early November of 2003, the Sun unleashed a powerful series of events known as the Halloween storms. The coronal mass ejections launched by the Sun produced several severe compressions of the magnetosphere that moved the magnetopause inside of geosynchronous orbit. Such events are of interest to satellite operators, and the ability to predict magnetopause crossings along a given orbit is an important space weather capability. In this paper we compare geosynchronous observations of magnetopause crossings during the Halloween storms to crossings determined from the Lyon-Fedder-Mobarry global magnetohydrodynamic simulation of the magnetosphere as well to predictions of several empirical models of the magnetopause position. We calculate basic statistical information about the predictions as well as several standard skill scores. We find that the current Lyon-Fedder-Mobarry simulation of the storm provides a slightly better prediction of the magnetopause position than the empirical models we examined for the extreme conditions present in this study. While this is not surprising, given that conditions during the Halloween storms were well outside the parameter space of the empirical models, it does point out the need for physics-based models that can predict the effects of the most extreme events that are of significant interest to users of space weather forecasts.

Predicting magnetopause crossings at geosynchronous orbit during the Halloween storms

This paper reports on the estimation of a dynamic model of the food manufacturing industry in Canada. Its major objectives are to analyze the determinants of investments and the production structure of the industry. An important finding of the study is that the hypothesis of instantaneous capital adjustment to changing market conditions is statistically rejected. Capital stock adjustment to optimal levels takes approximately two and one‐third years. Another result is that although the industry is responsive to price changes, a general pattern of inelastic factor demand and output supply prevails in the short run, intermediate run, and even in the long run.

Magnetic-field and medium-energy particle data from the AMPTE/CCE spacecraft are used to study substorm-associated ULF pulsations in the midnight sector at a radial distance of 8 to 9 earth radii. The particle data are used to identify ion injections and to detect the electric field of ULF waves. A case study of the events on May 23, 1985 shows that the waves have the properties of a fundamental-mode standing Alfven wave. It is suggested that these observations are evidence of substorm-associated standing Alfven waves in the nightside magnetosphere.
