Preservation of human tissue immersed for five years in fresh water of known temperature

Two human bodies were recovered from the waters of the Duluth, Minnesota harbor. Extensive adipocere formation resulted in remarkable preservation of gross anatomic features of internal organs. Total time of immersion could be precisely estimated at five years. Water temperature during those five years could also be accurately estimated by direct measurements taken during the year following recovery of the bodies and from information supplied by a local electric power generating company. Immersion occurred at the time of the year when water temperature was highest (70 degrees F [21 degrees C]) facilitating the rapid formation of adipocere. A proposed mechanism for formation of adipocere is described.     

The Nature of Borders and International Conflict: Revisiting Hypotheses on Territory

This study examines the utility of moving beyond a simple "on–off" dichotomous view of contiguous land borders. For each of the 301 contiguous land borders between states in the international system, measures of ease of interaction, salience, and overall border "vitalness" have been developed using Geographical Information Systems technology. These variables are used to test two major extant lines of thought in international relations literature, as well as our proposed alternative, regarding the expected effect of the "nature" of borders on interstate behavior. We conclude not only that the "nature" of contiguous borders matters but also that the relationship between each of the three border measures and the likelihood of conflict is curvilinear concave—with both high ease of interaction and high salience related to lower levels of conflict, and the middle range of both variables related to higher levels of conflict.     

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.     

Factors associated with breath test refusals in drunken driving arrests.

OBJECTIVE: Jurisdictions with per se breath alcohol legislation rely heavily on breath test evidence in prosecuting drunk driving cases. Depending on other legal considerations, where subjects refuse the breath test, prosecution may be more difficult. The objective was to identify factors significantly associated with the risk of test refusal. This knowledge would be relevant for improving the compliance rate. METHOD: A retrospective observational study evaluated drunken driving arrest records (n = 38,687) within Washington State during 2003 where breath tests were requested under implied consent legislation. The association was determined between the risk of test refusal and several categorical variables including: arresting agency, gender, race, age, accident involvement, repeat offense, pre-arrest breath test, driver's license and all possible two-way interactions. The association was quantified by odds ratios (OR) and 95% confidence intervals (CI) using a logistic regression model. RESULTS: The overall refusal rate was 19.7%. The single main effect variable associated with the greatest reduction in risk of refusal was the performance of a pre-arrest breath test (OR = 0.31, 95% CI 0.30-0.33). No single main effect variables showed significant association with an increased risk of refusal. Several two-way interactions, however, were significant. Other possible predictor variables, not included in the analysis, are also discussed. CONCLUSIONS: An arrested subject's decision to refuse the breath test is clearly a multivariate issue. Knowledge of these results should help in developing a jurisdictionally specific breath test compliance model by identifying the legal, demographic and procedural factors contributing most significantly to breath test refusal rates.

论海上火灾免责

海上火灾免责 ,从其定义、起因 ,到举证顺序 ,举证对象 ,也即火灾起因的举证责任和承运人过失的举证责任等至关重要的问题 ,我国立法上存在较明显的缺陷 ,一是未分清火灾举证责任的举证顺序。二是未区分火灾起因的举证责任与承运人过失的举证责任。三则有关举证责任的规定 ,含义模糊易引起歧义 ,实际上已经造成某些权威人士的错误解释。四则在保留“承运人本人”狭窄的范围的同时 ,却引进《汉堡规则》中的明示举证责任 ,而且有过之无不及。
