Components Analysis

The ionization constants p(sKa) reported for 41 weak acids of varying chemical type in ten water–DMSO solvent mixtures have been analysed by the SIMCA version of principal components analysis. This shows the data to fit a two-component model. The significance of the results for acidity function theory is discussed.

The Impact

This article examines individual responsiveness to the media's changing political agenda during the years from 1964 to 1980. In the context of a dynamic model, the data indicate that responsiveness is positively associated with education, political interest, and a social motivation to attend to public affairs. A two-component model, in which heightened involvement increases individuals' exposure to information but also decreases their receptivity to the impact of the messages, is considered in a multivariate analysis. Although the results are only suggestive, the exposure function appears to operate for all three variables, whereas the inhibitions owing to the integration of previous information are evident only for political interest. Some speculations are offered about how these results may elaborate models of democratic public choice.

AbstractSurface and core samples of Neh–nar Glacier in the Kashmir Valley have been analysed for the radionuclides 32Si. 210Pb, 40K, and 137Cs. The lateral and vertical profiles (at an altitude of about 4 140 m) reveal:(1)32Si activity decreasing slowly from the accumulation zone to 4 050 m altitude and then abruptly towards the snout.(2)Five zones of alternating high and low 210Pb activity in the surface samples.(3)An horizon at between 2 and 3 m depth containing 210Pb activity above natural levels. This horizon is also associated with 137Cs and a maximum in total ß activity.The ice samples have been dated on the basis of a simplified two–component model, the “fresh“contribution determined by 2l0Pb and the old component by 32Si. The following conclusions can be drawn from these observations:(1)The model age of the snout ice is c. 850 years.(2)The average rate of ice movement in the lower glacier is about 2 m/year, which compares well with the annual movement rate of 2.65 m/year observed since 1974.

Galactic Model

The interval method of estimating model parameters (MPs) for the Galaxy was suggested earlier (Kutuzov 1988). Intervals are proposed to be used both for observational estimates of galactic parameters (GPs) and for the values of MPs. In this work we consider a model as a tool for studying mutual interaction of GPs. Two-component model is considered (Kutuzov, Ossipkov 1989). We have to estimate the array P of eight MPs.

Policy And Planning

A two-component model is presented for the analysis of the economic impact of pollution abatement. The primary component is a dynamic input-output system in which the structure of the economy is related to the level of environmental control as well as to time. A submodel, which consists of the various abatement activities within each industry, is used to explore the underlying nature of structural changes which take place as a result of changes in environmental regulations. The usefulness of the overall model for policy and planning purposes is illustrated by an example in which the submodel is transformed into a linear-programming format.
