Methodological problems in negotiation research

SUMMARY

Despite a decade or two of researching negotiation, little more is known about it than before. Since the research methods available in communication science are varied and powerful and there is no lack of information or crucial data, the major impediments to progress must be the inability to formulate the most pertinent questions and to construct the most useful integration of information. Comprehension of negotiation depends on the methods used to accumulate this knowledge, that is observation and theory building. As in the case of other human behavioural research methodology, negotiation methodology has problems concerning theoretical assumptions providing the frame for theory development, the theories forming the basis for the selection or development of research methods and the methods determining the data observed. Methodological problems unique to negotiation research are the complexity of the phenomenon, the multi-disciplinarity, the lack of time resulting from the crisis-nature of negotiation and the present lack of methods to measure relationships between variables.     

Physical and chemical evidence remaining after the explosion of large improvised bombs. Part 1: firings of ammonium nitrate/sugar and urea nitrate

Recent criminal acts in the United Kingdom, United States and other countries have demonstrated the dangers to public safety from the criminal use of improvised explosives on a large scale. Four sets of trials were carried out over four years, partly in collaboration with the United States Federal Bureau of Investigation, involving the firing of large bombs, mostly fertilizer based. The principal objectives of the firings were to measure the physical effects of the explosions upon objects representative of those that would be found at a real bomb scene and to recover any chemical traces deposited on these objects. The results are intended for use as an aid in determining the approximate size and type of an explosive employed in a terrorist attack. This paper describes the background behind the trials, the procedures for preparation of witness materials and charges, and the collection and analysis of physical and chemical evidence.
