Reproduction of atypical bullet exit wounds

Contradictory findings from experiments designed for the reconstruction of the circumstances in crimes committed with firearms induced us to systematically investigate the conditions leading to the occurrence of non-typical bullet exit wounds. For this purpose, skin samples and pig heads were fired at with different types of small arms and, on the exit side, the skin was brought into contact with various materials. The bullet exits were investigated morphologically and by means of emission spectrum analysis. The results from these investigations are classified and discussed.     

Learning, multiple equilibria, and the state: Agriculture’s role

This article will argue that the state must learn to pursue productivity enhancing rather than predatory policies if rapid long-run development is to occur in poor countries. These productivity enhancing strategies will most likely involve investment coordination. However, such coordination of investment in manufacturing is likely to fail in less developed countries as a result of low productivity in the traditional, agricultural sector. More importantly, investment coordination in agriculture is more likely to be successful especially if this is a broad based investment strategy involving the bulk of the population. In this context, the state will learn effective policies for coordinating development. Alternatively, if the agricultural sector is ignored and productivity here remains low, investment coordination in manufacturing will likely fail, and the state will learn to become a predator.

Detection of cocaine metabolite in perspiration stain, menstrual bloodstain, and hair

Low nanogram and picogram quantities of cocaine metabolite equivalents were detected in extracts from perspiration stains, menstrual bloodstains, and hair using radioimmunoassay. The theory of drug inclusion in hair and its significance are discussed.     

Acute effects of carbon monoxide and cyanide on hepatic mitochondrial function

The effects of carbon monoxide and cyanide on the hepatic redox state and energy charge were investigated. Rats were used for the experiment under pentobarbital anesthesia. Immediately after laparotomy, a rat was placed in an animal chamber made of a transparent plastic box and exposed to a test gas for 3 min. Every test gas was produced in a gas chamber connected to the animal chamber with a flexible tube. HCN was produced from NaCN and H2SO4. In the CO inhalation experiment, various amounts of CO were introduced into the gas chamber. Immediately after an exposure, about 2 g liver was frozen in situ with a precooled clamp. Oozed blood from the wound surface was sampled. Concentrations of ATP, ADP, AMP, acetoacetate, and beta-hydroxybutyrate in hepatic mitochondria were determined, and the redox state and the energy charge were calculated. For cyanide as well as CO, significant negative correlations were found between the concentration in the blood and the redox state. The same held true for the energy charge. The redox state showed a slight increase at low concentrations of both gases; however, thereafter it began to decrease sharply with increases in concentrations. When concentrations of the toxicant in the blood reached certain levels, a kind of turning point, beyond which the redox state does not decrease any more, was observed. It was about 40% for HbCO and about 2.0 micrograms/ml for cyanide, and the points seemed to be related to the concentrations, beyond which cells are irreversibly damaged. On the other hand, the energy charge did not change at low concentrations. With an increase in toxicant concentrations, the energy charge decreased drastically. The rate of decrease in the energy charge became higher when blood concentrations exceeded certain levels. It was about 40% for HbCO and 2.0 micrograms/ml for cyanide. The presence of low levels of blood cyanide did not affect the relationship between the energy charge and the HbCO concentration.     

Capital punishment politics and policies in the States, 1977–1997

Since the U.S. Supreme Court ruled the death penalty constitutionalin 1976, thirty-eight states have readopted new capital punishmentstatutes consistent with Supreme Court decisions on procedural guidelines. While much of the literature about capital punishmentaddresses the legal aspects of the issue, this essay examines thepolitics of the major institutions of state government in the formulation of capital punishment policies. In some states, thereis agreement between key officials in the institutions on the desirability of, or opposition to, capital punishment. However, inmost other states, the debate over the appropriateness of deathpenalty policies is vigorously waged between the executive, legislative and judicial branches. Overall, 432 felons were executedin 30 states between 1977 and 1997. However, no executions haveoccurred in nine of these states. Twelve states have no provisionsfor the death penalty. The majority of executions since 1977 havetaken place in just six states. In addition to the abolitioniststates, the others can be categorized as (1) aggressive executioners,(2) occasional executioners, (3) reluctant executioners, and (4)nonusers where the death penalty has been restored for politicalpurposes but no executions have been carried out in over two decadesand none are likely to be in the immediate future given the minisculenumber of inmates on death row.     

I Blog Therefore I Am

Twenty-five years since the publication of Intimate Strangers: The Culture of Celebrity, this essay reflects on the extraordinary changes in the nature of celebrity, including its radical democratization by way of the internet. Such changes reflect old dilemmas and pose new challenges as the internet and publishing worlds begin to merge and print culture is left behind.     

Estimating mental health needs and service utilization among prison inmates.

A sample of 3,684 inmates in the New York State prison system was surveyed in May 1986 to determine the prevalence of psychiatric and functional disability and service utilization. It was estimated that 5 percent had a severe psychiatric disability, and 10 percent had significant psychiatric disability. The higher the level of disability, the greater the proportion of inmates that had received mental health services in the last 30 days and in the last year. Still, 45 percent of the severe disability group had no service contacts in the last year. Patterns of utilization differed significantly by sex (a greater proportion of women received services) and by race (a greater proportion of whites received services). The clinical factors associated with receipt of services varied considerably between men and women.
