Initial reports of domestic violence are generally made to law enforcement officers who must respond and intervene. A subset of these episodes involves cases in which the victim, and, in many instances her child(ren), have been taken hostage by her husband or partner. Moreover, there are indications that the number of such incidents is growing. The purpose of this project was twofold: (1) to provide one of the first reports on the prevalence and characteristics of these events, and (2) to more closely analyze domestic crisis (hostage) situations using actual case examples. All information was obtained from the Hostage Barricade Database System (HOBAS) of the FBIs Crisis Negotiation Unit. HOBAS is a postincident information collection tool which stores historical data from law enforcement agencies across the nation on hostage/barricade incidents. An examination of this database yielded different types of domestic hostage-taking acts and outcomes (e.g., tactical vs. negotiated resolutions, survival vs. death/injury of perpetrator and/or victim[s]). Implications of the findings, for future crisis negotiation efforts directed toward nonviolent resolution of these high-risk critical incidents, are discussed.  相似文献

A major feature of the Australian criminal justice system is that jurors assess witness credibility and are the ultimate finders of fact. Recognising the occasional fallibility of humans in detecting truth and deception, the jury's function may be assisted by highly regulated expert evidence about a variety of scientific techniques. A recent scientific development has been the invention of "brain fingerprinting" (BF) by Dr Larry Farwell in the United States. Brain fingerprinting measures brainwave functioning to detect awareness of crime-relevant information in order to distinguish between guilty and innocent suspects. This article considers whether BF could be used for crime investigation and adjudication in Australia. By examining the rules of expert evidence and the principles relating to "novel scientific evidence", the admissibility of BF in the various Australian jurisdictions is evaluated. The utility of BF in criminal investigations and counter-terrorism initiatives is also canvassed. The authors conclude that, at the present time, it is unlikely that expert testimony on BF will be admitted in Australian criminal trials. However, the technique potentially offers other benefits to the criminal justice system, thereby warranting its consideration as a "criminal and investigative tool of the future".  相似文献

The authors report on a case of postmortem washing of a body with bleach. An adult female victim was found nude in an alleyway with both hands removed in the City of Westminster, CO. Cause of death was attributed to severe blunt force trauma to the head. The victim had been dumped in the alleyway within 7 h of discovery. Evidence discovered at the crime scene and autopsy indicated that the murder and subsequent washing of the body with bleach occurred at a secondary location(s). The victim was wet to the touch, presenting a strong odor of bleach. Several "ribbon"-like burn patterns were observed on the victim's back and upper thighs. These burn marks were replicated by dowsing a deceased pig with an over-the-counter concentration of bleach.  相似文献

Although there are many roadside testing devices available for the screening of abused drugs, none of them can be used for the detection of ketamine, a popular abused drug in Hong Kong. In connection to local drug driving legislation, effective roadside detection of ketamine in suspected drug-impaired drivers has to be established. According to the drug evaluation and classification program (DEC), ketamine is classified in the phencyclidine (PCP) category. However, no study has been performed regarding the signs and symptoms exhibited by users under the influence of ketamine. In a study to develop a protocol for effective roadside detection of drug-impaired drivers, 62 volunteers exiting from discos were assessed using field impairment tests (FIT) that included measurements of three vital signs (i.e. body temperature, pulse rate and blood pressure), three eye examinations [pupil size, lack of convergence (LOC) and horizontal gaze nystagmus (HGN)] and four divided attention tests (Romberg, one-leg stand, finger-to-nose and walk-and-turn tests). Subsequent laboratory analysis of oral fluid and urine samples from the participants revealed the presence of common abused drugs in both the urine and oral fluid samples of 55 subjects. The remaining 7 subjects with no drug in their oral fluid samples were used as drug-free subjects. In addition, 10 volunteers from the laboratory who were regarded as drug-free subjects were also assessed using the same FIT. Among the 62 volunteers, 39 of them were detected with ketamine in their oral fluid. Of these ketamine users, 21 of them (54%) with only ketamine found in their oral fluid samples while the rest (18 subjects) of them had other drugs (i.e. MA, MDMA, benzodiazepines and/or THC) in addition to ketamine. Of the 21 ketamine-only users, 15 of them (71%) were successfully identified by FIT. It was found that when salivary ketamine concentrations were greater than 300 ng/mL, signs of impairment became evident, with over 90% detection rate using the FIT. By comparing the FIT observations on the 21 ketamine-only users with the drug-free subjects, the typical signs and symptoms observable for subjects under the influence of ketamine included LOC, HGN, elevated pulse rate and in general, failing the divided attention tests, especially the walk-and-turn and one-leg stand.  相似文献

Following the September 11, 2001 terrorist attacks, letters containing Bacillus anthracis were distributed through the United States postal system killing five people. A complex forensic investigation commenced to identify the perpetrator of these mailings. A novel liquid chromatography/mass spectrometry protocol for the qualitative detection of trace levels of meglumine and diatrizoate in dried spore preparations of B. anthracis was developed. Meglumine and diatrizoate are components of radiographic imaging products that have been used to purify bacterial spores. Two separate chromatographic assays using multiple mass spectrometric analyses were developed for the detection of meglumine and diatrizoate. The assays achieved limits of detection for meglumine and diatrizoate of 1.00 and 10.0 ng/mL, respectively. Bacillus cereus T strain spores were effectively used as a surrogate for B. anthracis spores during method development and validation. This protocol was successfully applied to limited evidentiary B. anthracis spore material, providing probative information to the investigators.  相似文献

This study examined the in vitro stability of 6-acetylmorphine (6AM) in horse blood, sheep vitreous humour (VH) and homogenised deer muscle stored under different storage conditions. The stability of 6AM in horse blood is of interest because many toxicological laboratories utilise this matrix for the preparation of blood calibration and check standards and the latter are typically stored during routine use. Data on the storage stability of 6AM in human VH is extremely limited and no data has been reported in muscle. In the absence of human samples, 6AM stability was demonstrated in sheep vitreous and deer muscle. Blood and VH were stored with and without NaF at room temperature (RT), 4 and -18°C for 84 days. Muscle tissue homogenates were prepared in water with and without NaF and also in phosphate buffer (pH 6.0) containing NaF. Homogenates were stored for 31 days at RT, 4 and -18°C. Morphine and 6AM were extracted using SPE and quantified by GC-ion trap-MS/MS. In the absence of NaF, 6AM could not be detected after 7 and 14 days in blood stored at RT and 4°C, respectively. Although at -18°C 6AM was stable for 7 days (12% loss), only 54% was detected by day 84. The addition of NaF to horse blood increased 6AM stability substantially at every temperature. Further, the rate of degradation was found to be significantly slower in blood preserved with 2% NaF compared with 1% NaF (p=.05). 6AM was stable for the study period in preserved blood (1 and 2% NaF) stored at -18°C. For laboratories utilising horse blood in the preparation of standards, preservation with 1% NaF (minimum) and storage at -18°C is recommended. The addition of NaF to VH was essential for 6AM stability. Irrespective of temperature substantial losses (≥ 42%) were observed in unpreserved sheep VH by day 7. In preserved VH the concentration declined by only 22% on day 7 following storage at RT and no loss observed in VH stored at 4 and -18°C at the same time. In muscle, 6AM was stable for 7 days in preserved samples stored at RT and in all samples stored at 4°C and below. The addition of NaF increased the stability of 6AM substantially in muscle. The increased stability of 6AM in VH and muscle preserved with fluoride was attributed to inhibition of bacterial action and the subsequent reduction in the rate of putrefaction of these tissues.  相似文献

ABSTRACT

According to the nationalisation hypothesis, it is sometimes argued that electoral lists competing at local elections under a national party label are more likely to win. Yet, in many countries, local lists are still much present. This article seeks to assess the attractiveness of local and national list labels at local elections. Following Rokkan’s hypothesis of the nationalisation of local politics, we test the role of socio-economic inequality on the success of electoral lists across local polities. Based on an original dataset distinguishing the labels of 1.012 electoral lists – be they local, mixed or national – in the 262 Walloon municipalities in Belgium, the multilevel regression demonstrates that local and mixed labels present a significant electoral advantage vis-à-vis national party labels. However, the article shows that this electoral gain decreases as economic inequalities increase: national labels, especially left-wing parties, attract more voters as inequalities rise.  相似文献

The eightieth anniversary of the Beveridge inquiry is a timely moment to consider how the landmark report is used within contemporary UK politics. Calls for a ‘new Beveridge’ reflect a desire for a rupture with the past and the creation of a radical new welfare consensus. But this reflects a misunderstanding: Beveridge's approach was organic in nature, building on decades of experimentation, politically contested rather than consensual, and intellectually pluralist rather than moored to a single ideological worldview. The real insight Beveridge offers us today flows not from his substantive agenda—which was rooted in a particular set of historic circumstances—but as an approach to securing social reform. Successful welfare advances over the last generation have drawn on these ‘Beveridgean instincts’. Rather than calling for a new twenty-first century blueprint to be handed down from above, reformers should build on experimentation and successful incremental change, from within the UK and abroad.  相似文献

Despite efforts to increase gender diversity and equality worldwide, women are still underrepresented in leadership positions in public bureaucracies. This article speaks to the debate on how organizational context, more specifically organizational decline, may influence gender representation in such leadership positions. Based on role congruity theory and glass cliff theory this article empirically examines whether and how excessive workforce reductions are associated with changes in the representation of women in leadership positions in Dutch civil service organizations. Panel analyses on administrative data show that women's representation in leadership positions varies over time, but is not significantly affected by excessive workforce reductions. Overall, the analyses do not provide evidence for a glass cliff for women in Dutch civil service organizations. Implications for theory and future research are discussed.  相似文献
