Toxicological findings in military aircraft fatalities from 1986-1990.

Toxicological findings in all military aircraft fatalities investigated by the Division of Forensic Toxicology at the Armed Forces Institute of Pathology from 1986-1990 are presented. Carbon monoxide saturation levels greater than 10% were found in 4% of the 535 cases where appropriate specimens were collected. Positive ethanol findings were more indicative of postmortem formation than antemortem consumption. In only 1 case were abused drugs (cannabinoids in a passenger) detected. Other drugs identified included nicotine, chloroquine and over-the-counter analgesic agents, antihistamines and sympathomimetic drugs.     

Aberrant radioimmunoassay results for cannabinoids in urine

False negative and false positive radioimmunoassay results for cannabinoids in urine are reported. Such results occur infrequently and appear to be due to non-specific binding of the radiolabel by interfering substances, possibly proteins, in the specimens. False negatives arise when these substances and the non-specifically bound radiolabel are precipitated by polyethylene glycol in the separation stage of the assay, increasing the radioactivity in the bound fraction and thus lowering the assay result. False positives occur when the interfering substances and non-specifically bound radiolabel remain in solution during the separation stage, increasing the radioactivity in the free fraction and giving an erroneously high result. False positives could also occur in assays involving solid-phase antibodies or second-antibody separations. Methanol treatment of the samples prior to analysis precipitates the interfering substances and eliminates the aberrant effect. The interfering substances have not been identified through common serum proteins and semen have been excluded. No common factor in the circumstances of the cases that can account for the results has been identified.     

Constitutional,legal and political problems of local government in Nigeria

The new Nigerian local government system was clearly intended by its creators to be a representative and democractic system of devolution. The speed with which elected councils have been dissolved and replaced by caretaker committees and state appointees contrasts strangely with the constitutional provision that there should be a system of local government by democratically elected local councils. The constitutionality of dissolution has been confused with the constitutionality of further local government reform. Dissolution should be seen as an emergency measure to be used rarely in cases of proven maladministration by a local government. Further reform and reorganization of a state's system of local government should be regarded as a legitimate power of the state legislature. The role given by the Constitution to local government should not be interpreted as entrenching the system. Constitutional amendment is not required should further reform be necessary.     

Evaluation of a lactate dehydrogenase-nitro blue tetrazolium method of detecting unapparent myocardial infarction using a standardised sampling technique

Using a standardised block technique, the microscopic lactate dehydrogenase-nitro blue tetrazolium (LDH-nitro BT) and conventional haematoxylin and eosin staining methods were used to investigate the presence of myocardial infarction in a series of fifty forensic autopsies. The microscopic LDH-nitro BT method was found to be reliable; however, it did not reveal the presence of myocardial infarction in any of the cases where this had not been suspected.     

Bias in the formulation of local government budget problems

Government budgets are premised on forecasts of revenues and expenditures. These forecasts are subject to both stochastic error and strategic manipulation. Circumstantial evidence in the budgeting literature and in the popular media suggest that government officials routinely bias the forecasts underlying budgets. The research reported here asked three primary questions: To what extent are budget forecasts systematically biased? Why? (Are fiscal and electoral variables systematically related to the magnitude and direction of the biases?) What political and ethical difference do the biases make? From the literature and an analysis of the incentives facing politicians and bureaucrats, we developed hypotheses about budget biases. These hypotheses were tested using time series data for the City of Pittsburgh, Pennsylvania (1941–1983); the City of San Diego, California (1950–1982); and the Pittsburgh (Pennsylvania) School District (1946–1983). In these locales over the periods examined, budgets were systematically pessimistic; revenues were underestimated and expenditures were overestimated. The fiscal and electoral factors hypothesized to account for this pessimism are, however, very mixed in their ability to explain the biases.     

Referendums in the Third World

Since the early 1960s many Third World countries have been attracted to referendums, with the earliest being held in Uruguay in 1917, Iraq in 1921 and Chile in 1925. Butler and Ranney(1978) identified referendums in Third World nations up to 1978, yet analysis of the political process and patterns of these referendums is lacking in the political science literature. It is the purpose of this paper to identify some of the patterns and processes common to African, Asian, Latin American and Middle Eastern referendums. The paper will examine briefly the Western democratic referendums, excluding the experience of Switzerland and Australia where referendums are an integral part of the constitutional and political process. Secondly, the general and regional Third World patterns will be examined. Thirdly, referendums in nine countries will be described; lastly, the paper will conclude with the identification of the common patterns and processes of Third World referendums. In this paper we are concerned with post- independence national level referendums; although, many referendums have been conducted on a subnational level and prior to independence.
