Screening for cannabinoids in blood using EMIT: concentrations of delta-9-tetrahydrocannabinol in relation to EMIT results.

The EMIT d.a.u. cannabinoid assay of methanolic extracts of blood was found to be usable as a screening method in cases of suspected impairment by cannabis, when delta-9-tetrahydrocannabinol (THC) was analysed in the subsequent assay. A prerequisite is that the blood sample is taken some time after cannabis smoking. When a cut-off limit corresponding to 50 nM delta-9-tetrahydrocannabinol carboxylic acid (17 ng/ml) was used, 86% of the EMIT positive blood samples contained THC concentrations above the cut-off limit of 1 nM (0.3 ng/ml). A high EMIT result gave a high probability of finding a high THC concentration in the subsequent confirmation analysis.     

Sexing of human clavicles using length and circumference measurements

Measurement of clavicular length and circumference, and computation of clavicular robustness and length-circumference product from 724 autopsied adults of known age, sex, and body length between the ages of 15 and 96 years produced useful sex-predictive values. This predominantly North American white population contained 560 males and 164 females with intact, nondeformed clavicles. Clavicle length and circumference and particularly their product have been found useful in sexing, but robustness as a single trait has not. Despite a significant overlap of male and female values, the use of single cutoff values allowed correct sex assignment of up to 93% of the entire study population, including 94% of males and 89% of females. The ratios of body length to clavicle circumference and to clavicle length are on average greater in women than in men. The former ratio yields male predictive values greater than 95% for those individuals with ratios falling below the cutoff value of 43, whereas the latter ratio is a relatively poor sex predictor.     

The Injustice of Enforced Equal Access to Transplant Operations: Rethinking Reckless Claims of Fairness

The globalizing or totalizing imposition of a particular understanding of justice, fairness, or equality, as seen, for example, in Canada's single health care system, which forbids the sale of private insurance and the purchase of better basic health care, cannot be justified in general secular terms because of the following limitations: (1) the plurality of understandings of justice, fairness, and equality, and (2) the inability to establish one understanding as canonical. The secular state lacks plausible moral authority for the coercive imposition of one such account on peaceable, consenting adults. This state of affairs, with regard to the weakness of human moral epistemological powers, means that the secular state fails to have the moral authority to forbid coercively the sale and purchase of organs. It further lacks the secular, moral authority to impose equal access to organ transplantations. Assertions of such authority amount to reckless claims of fairness, and for this reason, health care policy must be set within the constraints of limited, constitutional regimes.     

Microscopical study on estimation of time since death in skeletal remains

For the purpose of estimating time since death in skeletal remains, postmortem changes in human compact bones were examined by microradiography and electron microscopy. The UV-fluorescence of the peripheral zone of compact bone was also examined by microscopic spectrophotometry. Microradiographic examination revealed no morphological changes in bones left in the open air for long periods, except one of 15 years since death. In bones left in the soil, vacuoles of 5-10 microns diameter, which contained a honeycomb-like structure formed by small vacuoles of 0.5-1 microns diameter, were found in the peripheral zone of the substantia compacta approximately 5 years since death, and in bones of 6 years or more, this change extended to the mid-zone. In bones left in the sea for 4-5 years, vacuoles of 5-10 microns diameter were observed in the outer peripheral zone of the substantia compacta. The relative intensity of UV-fluorescence in bones dwindled with time since death and the correlation coefficient was considerably high.     

Beyond Dichotomy: Dwight Waldo and the Intertwined Politics–Administration Relationship

Dwight Waldo's conception of the politics–administration question might be better understood as a "relationship" that contains elements of separation and intermixture rather than a "dichotomy," according to this author-commentator.To suggest that Waldo came to support the dichotomy presumes agreement about the meaning of the concept that is missing in Waldo's writings and in the public administration literature.     

Deregistration issues in the US for foreign private issuers

The first 150 words of the full text of this article appear below. Key points

• While the passage of Sarbanes–Oxley in the USwas just one of the many causes for the lack of competitivenessof the US capital markets recently, it served to focus the attentionof foreign private issuers in the US on the difficulty and sometimesimpossibility of exiting the US capital markets.
• Unlike manyother jurisdictions, the process of deregistering in the USis distinct from process of delisting. The current rules forderegistration of foreign private issuers focus on the numberof US shareholders, regardless of how or where those shareholderspurchased their shares. In addition, foreign private issuers,were subject to complicated rules for counting US shareholders,and deregistration often would only suspend (not terminate)their reporting obligations.
• As a result of pressure from foreignprivate issuers, the SEC proposed new rules at the end of 2005to liberalize the existing deregistration regime for foreignprivate issuers. . . . [Full Text of this Article]
