Case involving differentiation of deer and human bone fragments

In a recent Louisiana forensic anthropology case, it was necessary to attempt species identification of six small bone fragments. The primary concern was whether or not they matched the fractured humerus of a woman killed by two shotgun blasts and then disposed of in the Mississippi River. These tiny fragments were recovered by law enforcement officers inside a jeep pickup and at the gas station where the vehicle had been cleaned. The police suspect claimed that these fragments were from a deer that he had recently killed. The small size of the pieces precluded positive recognition of human versus nonhuman origin based upon gross morphology and cortical thickness. Microscopic examination was possible. This analysis involved comparison of the unknown specimens to reference deer and human thin sections including bone recovered from the woman during autopsy. Examination of the jeep and gas station fragments revealed no plexiform bone, secondary (not primary) osteons, and variability in size and shape of the osteons and Haversian canals. These and other variables identified the bone fragments as human.     

THE EFFECTS OF SELECTION SYSTEM ON JURY COMPOSITION

The Supreme Court and judicial scholars have argued that the demographic composition of grand and petit juries is important. To the extent that composition is a function of the selection system used, this suggests that the method of selecting grand and petit jurors is important. This article tests the link between selection system and composition by comparing the representation of blacks, Mexican-Americans, and women on grand juries selected by commissioners with the same three classes' representation on grand juries selected at random from the voter registration lists. For these jurisdictions, only female representation is consistently higher under random selection procedures.     

Computer-Aided Instruction in Law: Theories, Techniques, and Trepidations

Legal education is only beginning to make use of the technological capabilities of computers as a medium for instructional design. In this article the authors show the applicability of computer-assisted instruction to law through programmed instructional techniques. They trace the two decades of development of computer-assisted instruction (CAI) in law, the use and misuse of the computer's capabilities, the impact of CAI on law student attitudes and performance, and the positive student endorsement. They carefully analyze the computer's capacity for use in memory drills, tutorial sessions, and simulation exercises. They do not offer an unrestricted endorsement of the computer's capabilities but hope for the continuing development of CAI in the legal education process.     

Analytical characterization of isoheroin

The synthesis of isoheroin is presented with the analytical data (mass spectroscopy [MS], nuclear magnetic resonance [NMR], infrared spectroscopy [IR], and gas liquid chromatography [GLC]) for this compound. Comparison between analytical results for heroin and isoheroin shows differentiation is possible.
