The use of soil chemistry data to address post-mortem diagenesis in bone mineral

The soluble and exchangeable ions for a soil profile from the Roonka archaeological site. Lower Murray Basin, South Australia, are compared with the total elemental content of the soils. Since the chemical composition of post-mortem ionic substitution phases and secondary minerals in archaeological bone will depend on the availability of ions to the soil solution under field conditions, it is suggested that models addressing diagenesis in bone employ soluble and exchangeable ions rather than total elemental soil data.     

Electoral and partisan influences on Australian fiscal policy from Menzies to Hawke

I examine the controversial questions of whether or not partisanship and electoral motives shape the fiscal policies of Australian governments. I also extend the partisan model of policy choice for the Australian case. Specifically, using time‐series data for the financial years 1962–63 through 1989–90,1 explore partisan and electoral influences on the overall fiscal stance and the personal income transfer payments of the Commonwealth government Results indicate that, net of the influences of inertia in the policy process and of variations in economic forces, partisanship and elections play significant roles in determining both overall fiscal policy and income transfer outlays. Analyses reveal that fiscal policies become more expansionary across the electoral cycle while Labor and coalition governments have large but diminishing partisan effects cm policy over their terms in office.     

A DYNAMIC INTRSECTORAL,MODEL OF REGIONAL ECONOMIC GROWTH*

ABSTRACT. The dynamic relationship between sectoral value added and regional economic growth is analyzed using a stochastic intersectoral model estimated by ordinary least squares and linear systems techniques. A state-space portion of the model identifies the time element of sedoral value added. Dynamic multipliers, tracing the temporal path of regional growth, are calculated for the state of Georgia over the period 1963–1986. This application shows that the impacts of sectoral shocks can follow cyclical as well as monotonic patterns and that the direction and magnitude of the impact may change over time.     

Charcot-Marie-Tooth disease from first description to genetic localization of mutations

Charcot-Marie-Tooth disease is a hereditary motor and sensory neuropathy first described in 1886. Our increasing knowledge of this disease correlates well with the development of methods used in neurology over the past 100 years. Although its physiopathology and treatment is still not fully understood, current developments in techniques are opening the way to future discoveries. We have divided its history into three theoretical periods: the first from 1886 to 1956, which was devoted to clinical and pathological study of the disease; the second from 1956 to 1982, which saw the development of electromyography in the investigation of neuromuscular diseases; and the last and current period based upon genetic research, using the methods of molecular biology.
