Raman Microspectroscopic Mapping: A Tool for Identification of Fused Materials in Fire Debris

Examination of fire debris can provide information about the types of materials which were present at the time of the fire to give insights for fire scene reconstruction and understanding compartment fire dynamics. This paper demonstrates the ability of Raman spectroscopy for material identification postfire in complex situations, such as the production of fused masses during fire dropdown. A validated Raman spectral library is combined with Raman mapping in three fire case studies, to determine the individual materials in the fused masses formed. The case studies accessed material combinations of several common polymers. Raman mapping was carried out on a 10 μm × 10 μm square of the masses. Material identification using this technique ranged from a high of 85% match to a low of 40% match. This work demonstrated that complex masses found in the fire debris can be resolved into the individual material components for identification and spatial distribution.     

Housing vouchers for the poor

Can the nation's social programs survive the push toward leaner appropriations, a greater use of the market, and a narrower definition of the needy? A program to provide housing assistance for the poor is proposed that fills all these requirements. Housing vouchers are found to be cheaper than other housing programs and more satisfactory for participants. Moreover, the political climate augers well for the new approach.     

Elitist theory and political tolerance in Western Europe

This paper addresses the problem of democratic elitism within the context of Western European politics. An entrenched assertion of the so-calledelitist theory of democracy is that elites are more strongly committed to democratic values such as political tolerance than are ordinary citizens. The processes through which elites become more tolerant include political socialization, resocialization, political practice, and experience. Some have even argued that elites are the primary carriers of thedemocratic creed. Our purpose here is to test several hypothese drawn from elitist theory. Relying on opinion surveys conducted in each of the twelve nations of the European Community in 1988, we focus on political tolerance. Our basic hypothesis is that political activism contributes to greater political tolerance. Special attention is given to a sample of opinion leaders as a test of the elitist theory. The analysis is conducted both at the level of the individual citizen and the level of the nation state. This is one of very few efforts to test elitist theory from a broad, cross-national perspective. Consequently, the analysis will be crucial in recasting elitist theory to comport more closely with empirical evidence.     

Cross-National Perspectives for Aiding Policy Choice

The field of public policy analysis, centered about practical choices, is being extended by this journal to include useful comparisons among nations or other political units, as well as borrowing or lesson-drawing. This extension should remain close to the practical orientation of the field, rather than seeking to contribute to those disciplinary theories that lack practical usefulness in the short term (several decades). Implications of this admonition are spelled out in the form of a list of suggested topics for articles in this journal.
