The consumption of Delta9-tetrahydrocannabinol (THC) as cannabis has been shown to result in impaired and culpable driving. Testing drivers for the presence of THC in blood is problematic as THC and its metabolites may remain in the blood for several days following its consumption, even though the drug may no longer have an influence on driving performance. In the present study, the aim was to assess whether performance on the standardised field sobriety tests (SFSTs) provides a sensitive measure of impaired driving behaviour following the consumption of THC. In a repeated measures design, 40 participants consumed cigarettes that contained either 0% THC (placebo), 1.74% THC (low dose) or 2.93% THC (high dose). For each condition, after smoking a cigarette, participants performed the SFSTs on three occasions (5, 55 and 105 min after the smoking procedure had been completed) as well as a simulated driving test on two occasions (30 and 80 min after the smoking procedure had been completed). The results revealed that driving performance was not significantly impaired 30 min after the consumption of THC but was significantly impaired 80 min after the consumption of THC in both the low and high dose conditions. The percentage of participants whose driving performance was correctly classified as either impaired or not impaired based on the SFSTs ranged between 65.8 and 76.3%, across the two THC conditions. The results suggest that performance on the SFSTs provides a moderate predictor of driving impairment following the consumption of THC and as such, the SFSTs may provide an appropriate screening tool for authorities that wish to assess the driving capabilities of individuals suspected of being under the influence of a drug other than alcohol.  相似文献

A forensic biologist is usually involved in the criminal justice system process somewhere between the police and the legal system, interacting in a practical context regularly and extensively with both. Forensic DNA research and development commonly involves initiatives that encroach into the neighbouring domains of the law enforcement or legal agencies. Despite this level of association, establishing meaningful cross-disciplinary communication and understanding within the justice system remains a challenge. As an example, there is an abundance of literature relating to forensic DNA profiling in legal and criminological periodicals. Such journals are perhaps outside the regular reading of forensic scientists and much of the legal discussion appears to go unnoticed. This situation is understandable; however, it is also undesirable particularly as forensic DNA developments are intertwined with significant changes in legislation and contentious issues of privacy, civil liberty and social justice. This paper attempts to address this shortcoming directly by summarising - from the viewpoint of a forensic scientist - some of the discussion in the legal literature. In particular the review focuses on discussion raising ideological and ethical concerns. Awareness of these views is of relevance to forensic science. It assists us to accurately place DNA evidence into context and to develop its role in achieving the broader criminal justice system objectives. Understanding the discussion also provides a way to enter the debate and communicate at an appropriate level the true potential of DNA to the legal community.  相似文献

Steamer accidents, through contact with the bucket wheel, are very seldom today. No publication of such a kind of fatal accident could be found in literature. We present the case of a fatal steamer accident, in which the findings of a blunt traumatization of a person by the ship was completely documented by post-mortem combined multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) examinations. A rupture of the aorta was detected using both radiological methods without use of radiopaque material. Radiological examination revealed a comminuted fracture of the thorax vertebrae at the same level as the aortic rupture. Injuries of the soft tissues of the back, caused by the bucket wheel of the steamer, were also diagnosed. In addition to the signs of blunt force trauma the findings of drowning such as an over inflation of the lungs, fluid in the stomach and duodenum were revealed. Furthermore, algological analysis detected diatoms in the lung tissue and blood from the left heart. Therefore, the cause of death was considered being a combination of fatal hemorrhage, caused by the aortic rupture, and drowning. We conclude that virtual autopsy using combined post-mortem MSCT and MRI is a useful tool for documentation, visualisation and analysis of the findings of blunt force trauma and drowning with a large potential in forensic medicine.  相似文献

A single nucleotide polymorphism (SNP) multiplex has been developed to analyse highly degraded and low copy number (LCN) DNA template, i.e. <100 pg, for scenarios including mass disaster identification. The multiplex consists of 20 autosomal non-coding loci plus Amelogenin for sex determination, amplified in a single tube PCR reaction and visualised on the Applied Biosystems 3100 capillary electrophoresis (CE) system. Allele-specific primers tailed with shared universal tag sequences were designed to speed multiplex design and balance the amplification efficiencies of all loci through the use of a single reverse and two differentially labelled allele denoting forward universal primers. As the multiplex is intended for use with samples too degraded for conventional profiling, a computer program was specifically developed to aid interpretation. Critical factors taken into account by the software include empirically determined extremes of heterozygous imbalance (Hb) and the drop-out threshold (Ht) defined as the maximum peak height of a surviving heterozygous allele, where its partner may have dropped out. The discrimination power of the system is estimated at 1 in 4.5 million, using a White Caucasian population database. Comparisons using artificially degraded samples profiled with both the SNP multiplex and AMPFISTR SGM plus (Applied Biosystems) demonstrated a greater likelihood of obtaining a profile using SNPs for certain sample types. Saliva stains degraded for 147 days generated an 81% complete SNP profile whilst short tandem repeats (STRs) were only 18% complete; similarly blood degraded for 243 days produced full SNP profiles but only 9% with STRs. Reproducibility studies showed concordance between SNP profiles for different sample types, such as blood, saliva, semen and hairs, for the same individual, both within and between different DNA extracts.  相似文献

The article presents a framework for better understanding the nature of performance in organisations involved in the provision of overseas development assistance (ODA). It uses a case study to illustrate the three main features of the framework which are: goals, performance assessment and performance management. It is asserted that a vibrant performance culture is one which links these features together to form an organisation capable of continual improvement through producing effective learning. Organisational culture determines the nature of linkages between the three sub‐systems. The article stresses how the notion of performance may extend beyond various forms of evaluation and scrutiny to being part of a sentient learning system rooted in an organisation's culture and structure. The article concludes with consideration of key issues associated with the generation of a reflexive learning organisation operating in the ODA sector. These are concerned with understanding the role and nature of systems, organisational vision, the embracing of diversity, training and accountability.

This review of country‐level performance assessment in donor agencies is primarily based upon the experiences documented by bilateral donors to developing countries. The review suggests that four emerging themes can be identified in the literature on country‐level performance review: ownership, decentralisation and leadership, accountability and learning and complexity. The review considers the implementation of ‘results‐based’ approaches used by a number of international agencies and examines their relationship with ‘evidence‐based’ approaches. A key challenge, in the development of performance assessment, is bringing in a stronger evidence‐based approach into the planning and evaluation of donor country‐level programmes.

Reform is a common theme in American public administration. During the twentieth century at least 12 major administrative reforms have taken place at the federal level and countless others in state and local governments. Frequently, these reforms have addressed the operation of public personnel management systems. Recent efforts associated with the reinventing government movement, for example, have proposed numerous alterations to civil service rules and procedures, and many jurisdictions have implemented significant changes in their personnel practices. This article examines the extent to which these kinds of personnel reforms have been implemented by state governments. A reform index is developed to document the considerable variation among the states in their approach to personnel practices. Several state characteristics are associated with scores on this index, including legislative professionalism, which bears a positive relationship to reform, and the level of unemployment within a state and the proportion of state employees associated with public employee unions, which are both negatively associated with reform.  相似文献
