This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain. 相似文献

Modern capital jurisprudence places special significance on judicial instructions to guide the discretion of the capital jury in reaching a penalty phase decision. Yet, previous social science research has raised doubts about the extent to which judicial instructions are generally understood by jurors and questioned their utility in producing intended effects. The present study measured the comprehension of the capital sentencing instruction employed in California. Data suggest widespread inability to define accurately the central concepts of aggravation and mitigation in use in virtually every state that currently has a death penalty statute, as well as the inability to distinguish properly the sentencing significance of the enumerated factors jurors are directed to use in reaching their life and death verdicts. In addition, an inordinate focus on the circumstances of the crime—to the exclusion of other potentially important factors—was identified, as well as special problems in comprehending the crucial concept of mitigation in constitutionally required ways.We would like to thank Suzanne Ban, Cori Nardello, and Maryanne Tagavilla for assistance in transcribing and content-analyzing the data. 相似文献

In the first half of the 1990s, some local government investment pools (LGIPs) suffered losses from derivatives investments. Although the losses came from derivatives, the actual cause of the losses was the violation of public-fund prudent investment practices. This article provides a strategy to prevent future losses for LGIPs' participants by looking at the pattern of return on investment of the pools. Our proposal is that rates of return on state pools that co-move with market rates are generally an indication of adherence to prudent investment practices. We demonstrate the viability of this proposal by using co-integration methodology. The implication is that if rates of return on a state pool do not co-move with market rates, they may indicate the violation of prudent investment practices. 相似文献

The bodies of socially isolated people may remain undiscovered in their own houses for prolonged periods. Occasionally the body is in situ for sufficient time to become skeletonised, or partially so. Medico-legal investigation of these cases is complicated by degradation and contamination of evidence. Thus, a multidisciplinary forensic investigation is recommended. The potential contributions of forensic pathology, anthropology, odontology and entomology are outlined here with reference to two cases that occurred in Victoria, Australia, in 2003. Forensic pathologists are often unable to determine the cause of death in skeletonised bodies, however, they may find evidence to support either a natural or unnatural mode of death, and they may describe skeletal pathology or trauma, and identify skeletal features to support radiological identification of the deceased. Anthropologists can provide supplementary evidence of skeletal trauma. Additionally, they can assess age, sex, stature and racial affiliation from skeletal remains. Odontologists can identify individuals through comparison with ante-mortem dental records; however, potential difficulties exist in identifying the treating dentist of a socially isolated person. Odontologists may also examine the teeth and oro-facial skeleton for trauma. Entomologists may estimate minimum death time and/or season of death. Entomological examination of insect remains may also confirm that a body has lain in situ for a considerable period. 相似文献
