Image analysis of gunshot residue on entry wounds. II--A statistical estimation of firing range.

A statistical investigation of the relationship between firing range and the amount and distribution of gunshot residue (GSR), used automated image analysis (IA) to quantify GSR deposit resulting from firings into pig skin, from distances ranging between contact and 45 cm. Overall, for a Ruger .22 semi-automatic rifle using CCI solid point, high velocity ammunition, the total area of GSR deposit on the skin sections decreased in a non-linear fashion with firing range. More specifically there were significant differences in the amount of GSR deposited from shots fired at contact compared with shots fired from distances between 2.5 and 45 cm; and between shots fired from a distance of 20 cm or less, with shots fired at a distance of 30 cm or more. In addition, GSR particles were heavily concentrated in the wound tract only for contact and close range shots at 2.5 cm, while the particle distribution was more uniform between the wound tract and the skin surfaces for shots fired from distances greater than 2.5 cm. Consequently, for future scientific investigations of gunshot fatalities, once standards have been established for the weapon and ammunition type in question, image analysis quantification of GSR deposited in and around the gunshot wound may be capable of providing a reliable, statistical basis for estimating firing range.     

Correlations on radioimmunoassay, fluorescence polarization immunoassay, and enzyme immunoassay of cannabis metabolites with gas chromatography/mass spectrometry analysis of 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine specimens.

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences.     

Looking Beyond the Bancoult Cases: International Law and the Prospect of Resettling the Chagos Islands

During the 1960s, the US government entered into an agreementwith the UK government to construct a military facility in theChagos Archipelago. The UK government excised the Archipelagofrom the colony of Mauritius and created the British IndianOcean Territory (BIOT). Diego Garcia was transferred to theUnited States and the indigenous people of the entire Archipelagowere secretly banished. This process led to their chronic impoverishment.In the Bancoult cases, the English courts held the exile tobe unlawful and that the Chagossian people possess a publiclaw right of abode in the Chagos Islands. This article examineswhether international law can facilitate the resettlement tothe Chagos Islands via recognition of BIOT's non-self-governingstatus. It also explores the prospect of securing compensationfor the loss of ancestral lands by reference to existing andevolving international standards on indigenous rights.     

Destructive Competition or Competition Destroyed? Regulatory Theory and the History of Irish Road Transportation Legislation

The principal aim of our study is to contribute to the debate over whether regulation is enacted in the interest of consumers, producers, political agents, or some combination of these. We examine the legislative debates and subsequent regulatory bills surrounding road transportation regulation in Ireland in light of the three dominant theories which purport to explain the existence of regulation: the public interest theory and the so-called Chicago and Virginia theories. A unique feature of our study is an attempt to integrate specific rhetorical concepts used in the public policy debates into the theoretical analysis of regulation. One noteworthy conclusion of our study is that theories of economic processes affect the shaping and results of public policy.     

Occupational Class and Vote in the 1949 Norwegian Election. Research Note

In 1948–49 the Sociology Office of the University of Oslo, under the guidance of Prof. Paul Lazarsfeld of Columbia University, initiated a series of studies on the Norwegian economic planning system. Part of this Planning Project was a national election survey in the fall of 1949, on a modified probability sample of 2600 people. The results show the paramount influence of economic class on voting, interpreting class as a combination of employer/employee relationship, property ownership, prestige-status, and income. Indicators of the homogeneity of class environment also played a role. Given the occupational structure of Norway, the Labor party had to win over part of the non-working-class population to obtain control of the government. They did this by winning about 1/3 of the white-collar vote, and about 1/4 of the farmers and fishermen. The policies of economic stabilization - control of inflation through price controls, wage controls, food subsidies, and rationing, and maintenance of full employment under conditions of "suppressed inflation" - were crucial to winning over these white-collar and farm voters.
