The authors have proposed a quantitative method for assessing weight of evidence in the case where a fingermark from a crime scene is compared with a set of control prints from the ten fingers of a suspect. The approach is based on the notion of calculating a Likelihood Ratio (LR) that addresses a pair of propositions relating to the individual who left the crime mark. The current method considers only information extracted from minutiae, such as location, direction and type. It does not consider other information usually taken into account by fingerprint examiners, such as the general pattern of the ridge flow on the mark and the control prints. In this paper, we propose an improvement to our model that allows a fingerprint examiner to take advantage of pattern information when assessing the evidential weight to be assigned to a fingerprint comparison. We present an extension of the formal analysis proposed earlier and we illustrate our approach with an example.  相似文献

Boards and associations within forensic science have long been accepted as vehicles for the development and dissemination of protocols and recommendations for practice. Recent controversies surrounding bite mark analyses have brought the methods and practices of forensic dentists to the attention of both the courts and the media. In the mid-eighties the American Board of Forensic Odontology developed guidelines for bite mark analysis in response to unfavorable commentaries on the discipline by legal observers. The purpose of this study is to examine the adherence of board certified and noncertified forensic dentists to the guidelines for collection of evidence from bite mark suspects. A questionnaire was employed during an American Academy of Forensic Sciences meeting. Results showed that, in general, when the odontologists collected evidence they did adhere to the guidelines, although collection of salivary samples was not common. Of concern is the large number of odontologists who do not collect their own evidence from suspects. Police officers or other individuals often perform this task and therefore the guidelines must be disseminated to these groups to ensure that the maximum yield is obtained from bite mark evidence. A review of the materials used to collect evidence is also included with details of applications in forensic science.  相似文献

This rule updates the reference to the required resident assessment tool for State homes that receive per diem from VA for providing nursing home care to veterans. It requires State nursing homes receiving per diem from VA to use the most recent version of the Centers for Medicare and Medicaid Services (CMS) Resident Assessment Instrument/Minimum Data Set (MDS), which is version 3.0. This will ensure that the standard used to assess veterans is the same as the standard applicable to Medicare and Medicaid beneficiaries.  相似文献

This rulemaking controls the chemical N-phenethyl-4-piperidone (NPP) as a List I chemical under the Controlled Substances Act (CSA) (21 U.S.C. 801 et seq.). Clandestine laboratories are using this chemical to illicitly manufacture the schedule II controlled substance fentanyl. The recent distribution of illicitly manufactured fentanyl has caused an unprecedented outbreak of hundreds of suspected fentanyl-related overdoses, at least 972 confirmed fentanyl-related deaths, and 162 suspected fentanyl-related deaths occurring mostly in Delaware, Illinois, Maryland, Michigan, Missouri, New Jersey, and Pennsylvania. NPP has been identified as the starting material in several seized fentanyl clandestine laboratories. In addition to DEA's concern regarding the deaths associated with illicitly manufactured fentanyl, DEA is extremely concerned about the safety of law enforcement officers encountering these clandestine laboratories. Therefore, DEA is regulating NPP as a List I chemical through this Interim Rulemaking. DEA is soliciting comments on this Interim Rule. This rulemaking will subject handlers of NPP to the chemical regulatory provisions of the CSA and its implementing regulations, including 21 CFR Parts 1309, 1310, 1313, and 1316. This rulemaking does not establish a threshold for domestic and international transactions of NPP. As such, all transactions involving NPP, regardless of size, shall be regulated. This rulemaking also specifies that chemical mixtures containing NPP will not be exempt from regulatory requirements at any concentration. Therefore, all transactions of chemical mixtures containing any quantity of NPP will be regulated and will be subject to control under the CSA.  相似文献

The authors describe 3 cases where Y-chromosomal systems were used for typing the biological traces. In the first case, a murder, for the major amount of cell material found on a dish towel (and analysed two years after the crime) female persons were excluded for the system amelogenin and Y-chromosomal systems. A brother of the victim could not be excluded for autosomal STR-systems. Upon confrontation with the results of the DNA-analysis (among other things), this brother confessed the murder of his sister some days later. He was found guilty by the court. In the second case described, a rape of two girls, many traces were analysed parallely with Y-chromosomal and autosomal PCR-systems. The objects where male DNA matching the suspect were found (a paper tissue, a sweat shirt and the knickers of the girls), also showed small amounts of alleles matching with the suspect for autosomal systems, while the major part in these systems was from the girls. The suspect was sentenced to many years imprisonment. In the third case, a possible rape of a young woman, a stained microscope slide of a vaginal swab had to be examined. Microscopically a few sperm heads could be seen in a surplus of leucocytes. The male proportion could be analysed only in the Y-chromosomal systems, not in the autosomal ones. For the frequency calculation of the Y-chromosomal allele combination the haplotype data bank of the Institute for Legal Medicine of the Humboldt university in Berlin was indispensable.  相似文献

The modern Swedish population is a mixture of people that originate from different parts of the world. This is also the truth for the clients participating in the paternity cases investigated at the department. Calculations based on a Swedish frequency database only, could give us overestimated figures of probability and power of exclusion in cases including clients with a genetic background other than Swedish. Here, we describe allele frequencies regarding the markers in the Identifiler-kit. We have compared three sets of population samples; Swedish, European and non-European to investigate how these three groups of population samples differ. Also, all three population sets were compared to data reported from other European and non-European populations.Swedish allele frequencies for the 15 autosomal STRs included in the Identifiler kit were obtained from unrelated blood donors with Swedish names. The European and non-European frequencies were based on DNA-profiles of alleged fathers from our paternity cases in 2005 and 2006.  相似文献

The purpose of this study is to test the accuracy of seven discriminant function equations that have been derived by Steyn and Is?an for sex determination using measurements of the femur and tibia of South Africans of European descent (SAED). While the validity of some of the discriminant functions has been assessed by the authors who derived them, no previous independent study has been carried out to assess the accuracy of these equations. These equations have not been tested on skeletons located outside of the Gauteng province. A suite of measurements were taken on 272 femora and 256 tibiae obtained from four South African skeletal collections. The validity of each of the previously published equations for the femur was confirmed. However, two functions of the tibia showed low accuracy rates, most likely due to difficulties in recording the distal epiphyseal breadth measurement, and thus were found to be poor assessors of sex.  相似文献

Reference material was synthesised for 21 substances that are frequently present as synthetic impurities, i.e. by-products, in illicitly produced amphetamine. Each of these substances is a typical by-product for at least one of the three approaches most often used to synthesise amphetamine, namely, the Leuckart, the reductive amination of benzyl methyl ketone, and the nitrostyrene routes. A large body of data on the substances was recorded, including the following: mass spectra, ultraviolet spectra, Fourier transform infrared spectra, infrared spectra in gas phase, and 1H NMR and 13C NMR spectra.  相似文献

In 1990, Congress enacted the Americans with Disabilities Act (ADA). This Note examines the legislative history of the ADA and uncovers Congress's intent to impose a duty on health care providers to treat people with disabilities unless an individual poses a "direct threat" to the health or safety of others. This Note posits that, with the passage of the ADA, Congress imposed a statutory duty on health care providers to give care to people infected with HIV who qualify under the statute. This Note concludes that while the "direct threat" exception may lessen the impact of the ADA, those infected with HIV should enjoy greater access to health care than ever before.  相似文献

The effectiveness of the fluorogenic reagent NBD chloride has been compared with the popular colour reagent ninhydrin for the development of fingerprints on paper. NBD chloride was found to be more sensitive than ninhydrin for moderately old fingerprints (3–9 months) and never inferior to ninhydrin in all other cases. A qualitative evaluation technique was used to establish the relative efficiency of each method. This is based on the number of points of identification, assessed on a 1–4 scale, where 4 represents a courtworthy print (> 12 points) and 1 represents a print containing no identification points.  相似文献

The Department of Veterans Affairs (VA) amends its regulations concerning per diem payments to States to permit continuation of such payments in some situations for veterans who have been evacuated from a State home as a result of an emergency. Per diem is the daily rate paid by VA to a State for providing a specified level of care to eligible veterans in a facility that is officially recognized and certified by VA. This final rule authorizes VA to continue to pay per diem when veterans for whom VA is paying per diem are evacuated as a result of an emergency from a State home to a facility that is not recognized by VA as a State home. The rule requires, in order for per diem payments to continue while the veteran is relocated due to an emergency, that an appropriate VA official determine whether an emergency exists and whether the facility to which veterans may be evacuated (evacuation facility) complies with certain minimum standards. The rule establishes the minimum standards that facilities to which veterans are evacuated must meet in order for States to continue receiving per diem for relocated veterans. These standards also apply to evacuation facilities when veterans are evacuated from contract nursing homes.  相似文献

美国《联邦证据规则》作为英美成文证据法的典范,常常受到我国学者的青睐.但该规则并非可资借鉴的唯一美国模式.生效于1967年的《加州证据法典》被普遍认为在对普通法规则的修正方面获得了成功.其影响不仅限于加州地区,而且美国《联邦证据规则》中许多条款都曾以《加州证据法典》中的相应规定为范本.但在许多情况下,《加州证据法典》与《联邦联邦规则》在调整同一问题的规定之间也存在着明显的差异,它们体现了起草者不同的政策选择.理解这些差异有助于中国证据法改革者做出最契合本国文化和法律价值观的证据性选择.  相似文献

Abstract: Cranial neural tube defect, or anencephaly, is the absence of normal brain development because of severe developmental defect in the fetus. While the current incidence of human anencephaly ranges between 1 to 5 per 1000 births, and was higher prior to folic acid supplementation, there is no discussion of anencephaly diagnosis in the forensic literature and only one published example from the archeological record. This article presents both qualitative observations of abnormal cranial elements and an osteometric method to quantitatively determine anencephaly from forensic recovery contexts where taphonomic variables may otherwise mask diagnostic characteristics. Evidence is presented for only the second case of anencephaly diagnosed from a burial context, and the first not involving soft tissue mummification. The initial recognition and accurate prediction of anencephaly is a significant contribution to investigators recovering found human fetal remains.  相似文献

Optimisation and harmonisation of analytical and statistical methodology have been carried out between two forensic laboratories (Lausanne, CH and Lyon, F) in order to provide drug intelligence for cross-border cocaine seizures. The aim was to improve the gas chromatographic analysis of cocaine samples for profiling. Some important validation parameters were tested to verify the developed method and demonstrate its profiling capacity: the selectivity of the method with retention time reproducibility, the choice of a derivatisation agent improving the chromatography (MSTFA, BSA, TMSI and BSTFA+TMCS 1%), the cutting agents influence (matrix effect), the influence of the sample storage conditions and the sample quantity to weigh for analyses. Eight main alkaloids, which represent the sample signature, have been selected: ecgonine methyl ester, ecgonine, tropacocaine, benzoylecgonine, norcocaine, cis- and trans-cinnamoylcocaine and 3,4,5-trimethoxycocaine. Their stability in the solvent used (CHCl(3)/pyridine) was demonstrated. In order to reach the final objective, which is the comparison of samples seized and analyzed in two different laboratories, the harmonisation of the profiling method between the two laboratories had to be ensured and is the subject of ongoing research.  相似文献
