Abstract: In this case report, potential interferences from an improvised fire‐extinguishing agent, a dishwashing liquid, containing linear alkylbenzene sulfonates (LAS), was studied. The presence of linear alkylbenzenes (LABs) in the fire debris sample was identified from the summed ion profile (SIP) analysis. It was found that the LAS from dishwashing liquids produce LABs by thermal degradation. Direct pyrolysis of a LAS‐containing dishwashing liquid at 300°C yielded a distribution of LABs in the SIP. LABs began to break down at pyrolysis temperatures between 450 and 500°C and completely break down by 800°C. Observed pyrolysis breakdown products of LABs included toluene, ethylbenzene, meta‐, para‐, and ortho‐xylenes, propylbenzene, indane, naphthalene, and 1‐ and 2‐methylnaphthalenes. These data suggested the presence of LABs in fire debris evidence might complicate subsequent analysis because their breakdown products contained some of the target compounds common to ignitable liquid identification. Therefore, a positive determination of the presence of foreign ignitable liquids should be carefully evaluated when there is a presence of LABs in the SIP. 相似文献

Witness protection (procedural and non-procedural) concept has become firmly entrenched in modern criminal justice systems for purposes of securing the much needed testimony and amelioration of vulnerable witnesses’ circumstances. Witness protective measures have been used mostly in serious and organized crime prosecutions. Notwithstanding this, Malawi’s criminal justice system including its reforms has completely ignored this leaving witnesses vulnerable to tampering and intimidation. This article explores Malawi’s circumstances by focusing on serious and organised crime such as corruption and money laundering. It further offers some recommendations and policy perspectives as to what can possibly be done to ameliorate the witness situation. 相似文献

This article reinterprets the discursive terms and cultural meanings that redefined the legal campaign against Big Tobacco during recent decades. We underline the palpable shift from a conventional tort‐based logic of products liability claims, which most analysts emphasize, to a logic incorporating key features identified with criminal law or “crimtorts.” The study builds on legal mobilization theory and combines narrative history of events with systematic analysis of media coverage across a twenty‐year period to demonstrate how Big Tobacco was criminalized over two decades. 相似文献

This paper outlines evolution of the policy response to conflicts of interest analysts face in offering investment advice to investors when the company they follow may also buy merchant banking services from their employer. Both in the US and the UK on a both statutory and common law basis the response has been one of to disclose and let market participants price the implied conflict or simply rebut the advice given. An efficient market can price conflicts and by implication unravel any potential damage to shareholder wealth induced by analysts’ conflicts of interests in this view. I consider the impact the presence of “noise traders” in financial markets may have on the welfare implications of this sort of policy stance. The presence of noise traders casts doubt on the benign impact of conflicts of interest in financial markets. In particular the presence of noise induced variance in analyst’s forecasts implies disclosure based remedies may be ineffective in mitigating the harm of analyst’s conflicts of interest. 相似文献

Forensic Evidence and Criminal Investigations: The Impact of Ballistics Information on the Investigation of Violent Crime in Nine Cities, 下载免费PDF全文

We explore the impact of information from ballistics imaging hit reports on the investigation into violent crimes. Ballistics imaging hits link two crimes involving the same firearm by forensically matching tool marks on the fired bullets or cartridge cases. Interview data collected from detectives who received a hit report were used to explore the relationship between the presence of a hit report and outcomes in 65 gun‐related violent crime investigations in nine U.S. police agencies. Findings indicate hit reports rarely contribute to identification, arrest, charging, or sentencing of suspects, because of delays in producing hit reports. On average, hit reports were completed 181.4 days after the focal crime. This delay forces investigations to proceed without the benefit of information from ballistics analysis. Additionally, hit reports rarely contained detailed information that was immediately useful to investigators. Instead, hit reports required additional research by the investigator to unlock useful information. 相似文献

Restorative justice (RJ) encompasses a widely diverging set of practices whereby those most affected by crime are encouraged to meet, to discuss the effects of harms caused by one party to another, and to agree upon the best possible redress of harms when appropriate. In its inception in the late 1970s, RJ was conceptualized and developed as an alternative to formal criminal justice practices. Since this time, however, RJ has largely moved from being an alternative to criminal justice practices to an ‘alternative’ practice within criminal justice systems. This institutionalization has resulted in the significant growth of RJ practices, but has also resulted in RJ being used for criminal justice system goals that are at odds with the needs of victims or offenders. This paper examines the use of the Youth Justice Group Conferencing Program in Victoria, Australia. Drawing from interviews with conference conveners, our research highlights problems related to administrative ‘constraints’ and ‘co-options’ in conferencing in terms of referrals, preparation of conference participants, and victim participation. Following presentation of findings, we conclude with a discussion of implications for the use of RJ within a highly institutionalized setting. 相似文献

The current study is the first to implement and evaluate a group-based trauma-specific program for adolescents in a secure accommodation facility in Scotland. A randomized control and qualitative pilot study compared an intervention group (n = 10), who received Teaching Recovery Techniques, to a waitlist control group (n = 7). Measures included subjective units of disturbance (SUDs), standardized trauma symptom questionnaires, and analysis of behavior monitoring logs. Adolescent interviews (n = 10) and a presenter focus group (n = 4) assessed program experience and views on future development. Sessions were videoed and analyzed for program adherence. Analysis involved MANOVA, and a quasi-qualitative thematic approach for participant views. Adolescents reported high SUDs and a range of trauma symptoms. A large effect size was found for reduced SUDs (d = 1.10) and positive trends were identified for symptoms and behavior change in the intervention group. Program adaptations included smaller groups, the use of visual materials and liaison with care staff to facilitate generalization. Recommendations are made for program development and large scale evaluation. 相似文献

In 1994 Rwanda was devastated by genocide that killed hundreds of thousands of people and destroyed the country’s infrastructure. The credibility of the criminal justice system was questioned following the genocide because it had failed to stop the slaughter and may have contributed to it. In order to address these concerns, Rwanda rebuilt its criminal justice system in light of its history and troubled past. The success of the reestablishment may be debated but there can be no question that Rwanda had a tabula rasa with which to form an effective criminal justice system. Examining the law details the ideals of the criminal justice system as established post-genocide. These ideals exemplify the democratic process. Examining current events allows for a practical assessment of the success of the new system. In both theory and practice the country’s criminal justice system has changed drastically since 1994. 相似文献

Detection of trace quantities of explosive residues plays a key role in military, civilian, and counter-terrorism applications. To advance explosives sensor technology, current methods will need to become cheaper and portable while maintaining sensitivity and selectivity. The detection of common explosives including trinitrotoluene (TNT), cyclotrimethylenetrinitramine, cyclotetramethylene-tetranitramine, pentaerythritol tetranitrate, 2,4,6-trinitrophenyl-N-methylnitramine, and trinitroglycerin may be carried out using a three-step process combining "turn-off" and "turn-on" fluorimetric sensing. This process first detects nitroaromatic explosives by their quenching of green luminescence of polymetalloles (lambda em approximately 400-510 nm). The second step places down a thin film of 2,3-diaminonaphthalene (DAN) while "erasing" the polymetallole luminescence. The final step completes the reaction of the nitramines and/or nitrate esters with DAN resulting in the formation of a blue luminescent traizole complex (lambda(em) = 450 nm) providing a "turn-on" response for nitramine and nitrate ester-based explosives. Detection limits as low as 2 ng are observed. Solid-state detection of production line explosives demonstrates the applicability of this method to real world situations. This method offers a sensitive and selective detection process for a diverse group of the most common high explosives used in military and terrorist applications today. 相似文献
