Gc in bloodstains

Gc-subtyping was carried out on blood stains that had been made on cotton and glass and stored under a variety of conditions ranging from -20 degrees to +56 degrees C. The limits of detection ranged from 2 weeks at 56 degrees C up to 92 weeks at +4 degrees C and greater than 116 weeks at -20 degrees C. Additional bands that have been reported in other studies could not be detected during this study, and this difference is thought to be due to storage of the samples in the liquid state.     

The electoral college and the rational vote

We have shown first, that if the electoral college was abolished the theoretically measured power of voters would increase and second, that in presidential elections the measure of voting power used does in fact have a highly significant impact on the decision as to whether or not to vote. Thus, the analysis predicts that the abolition of the electoral college would have a significant impact on voter participation. From a policy viewpoint, if we view participation in elections as desirable, this could be used as an argument in favor of direct election of the president. From a scientific viewpoint, we are able to make a strong and unambiguous prediction about the results of a (possible) future event from theoretical considerations. If the electoral college should be abolished, it will be possible to test our predictions. In addition, we have provided a further test of the rational behavior view of electoral participation and have shown that this model applies to presidential elections. Finally, we have shown that the theoretical measure of voting power does predict actual behavior.     

The effectiveness of licensing

Suggesting that licensing may not only fail to accomplish its intended purpose, but may be counterproductive, the author asserts that licensing may not improve the quality of professional services, that licensing boards fail to discipline unethical or incompetent practitioners, and that actions taken against the unlicensed are more often aimed at eliminating competition, not incompetence. In addition, licensing laws may have negative side effects, including an increase in the cost of professional services, the creation of shortages and maldistributions in supply, ineffective use of paraprofessionals, and impediments to needed reforms in education, training, and services. He concludes that equally effective alternatives may be available that are less expensive and have less negative impact, and advocates a system of registration for all practitioners, as well as making other suggestions to improve the overall functioning of licensing boards. Finally, because of political realities, the author proposes a compromise between his ideal model and the current system.     

Further evaluation of immunocytochemical staining in the diagnosis of early myocardial ischaemic/hypoxic damage

The pattern of immunocytochemical staining with antibodies to caeruloplasmin, myosin, myoglobin and C-reactive protein seen in myocardium taken from deaths with macroscopic evidence of myocardial infarction and/or significant coronary artery atherosclerosis and from deaths with neither of these lesions has been correlated with H&E, PTAH and HBFP staining of myocardium and circumstances of each death indicative of antemortem hypoxia and/or ischaemia. Loss of staining with these antibodies correlated well with fuchsinorrhagia and both techniques are more sensitive than H&E and PTAH staining in the detection of early ischaemic/hypoxic damage to myocardium. However, their sensitivity is such that they appear to detect agonal changes and, therefore, cannot be used for specific diagnosis of early myocardial infarction.

The shielding capacity of the standard military flak jacket against ballistic injury to the kidney

An animal model was designed to evaluate the ability of the standard military flak jacket to protect the kidneys from direct ballistic trauma. Yorkshire swine were anesthetized and their flanks were protected by flak jackets. Ballistic insults ranging from a low-velocity handgun to a high-velocity rifle were evaluated. The results demonstrate that a flak jacket provides adequate protection against low- and mid-velocity projectiles since none of the animals from this group had evidence of internal trauma and because only minor superficial surgical attention would have been required. Survivability in each case was considered to be excellent. The flak jacket failed to provide any protection against several types of high-velocity bullets. These weapons caused severe internal injury to the genitourinary system as well as to other major organ systems. Survival would have been unlikely.
