Structure and Process in Consociationalism and Federalism

It is relatively easy to characterize the institutional structureof a country as consociational or federal. The task is muchmore difficult if we turn from structure to the decision process.Within a given structure, there may be a great deal of variationwith regard to the decision process. Data for such variationare given for the decision process in Switzerland for whichthe following four types are distinguished: (1) consociationaland federal, (2) consociational and unitary, (3) competitiveand federal, and (4) competitive and unitary. Difficulties arediscussed in aggregating from such a variation to a measurefor the prevailing decision process in a country as a whole.It is suggested that the problem be disaggregated and that decisionprocesses be compared for particular issues. This can be doneboth across and within countries.     

Sequencing of intersecting lines by combined lifting process and scanning electron microscopy

The chronological order in which two intersecting writing or typed strokes were made can be determined for several combinations of writing media by scanning electron microscope (SEM) examination, a lifting and transfer technique using Kromekote paper, or a combination of the transfer technique followed by SEM examination of the remaining material in the intersection. When non-destructive examination cannot provide unambiguous determination of sequence, judicious choice by the document examiner of which technique to use for a given combination of writing media and paper type can be made using known characteristics of the materials involved. The range of line-crossings which can be reliably sequenced is greater using a combined transfer and SEM technique than when the examination is limited to either technique alone.     

A comparison of the use of visible microspectrometry and high performance thin layer chromatography for the discrimination of aqueous inks used in porous tip and roller ball pens

Ink lines made by porous tip and roller ball pens have been examined by high performance thin layer chromatography (HPTLC) and by transmission microspectrophotometry (VM) in the visible region. Better discrimination between apparently similar coloured inks was obtained with HPTLC but VM has value as an additional technique for ink examination.
