Samples taken from over 200 seizures of imported illicit heroin preparations of known geographical origin have been examined by gas liquid chromatography (GLC). The chromatographic characteristics were considered in conjunction with the physical appearance of the materials and it was found possible in many instances to discriminate between samples of different origin. Thus by carrying out GLC and HPLC and a visual inspection on a sample of unknown provenance, it may be possible to give an opinion as to its geographical origin. 相似文献
Instantaneous first impressions of facial trustworthiness influence the manner in which observers evaluate ensuing information about stranger targets [e.g. Porter, S., &; ten Brinke, L. (2009). Dangerous decisions: A theoretical framework for understanding how judges assess credibility in the courtroom. Legal and Criminological Psychology, 14, 119–134. doi:10.1348/135532508X281520]. In two studies, we examined the association between perceptions of general trustworthiness and honesty assessments in an extremely high-stakes sample – individuals publicly pleading for the return of a missing relative, half of whom had killed the missing individual. In Study 1, observers (N?=?131) provided trustworthiness ratings – either before or after viewing and evaluating the honesty of videotaped or audio-only pleas – for a still image that depicted a neutral expression on the face of each pleader. In Study 2, observers (N?=?220) evaluated the sincerity of audio pleas paired either with an untrustworthy-looking target, a trustworthy-looking target, or no target face. Collectively, our findings indicated that first impressions of trait trustworthiness form the basis of state judgments of honesty, potentially contributing to misguided credibility assessments and miscarriages of justice in the legal system. 相似文献
Drawing on prior theoretical and empirical work on survey participation, this study develops one potential method for increasing response rates and response quality in correctional surveys. Specifically, we hypothesize that providing inmates with a superficial survey choice (SSC)—that is, a choice between completing either of two voluntary surveys that are actually differently ordered versions of the same questionnaire—will increase their motivation both to participate in a given survey and to respond thoughtfully to the questions asked therein.
Methods
We test the effectiveness of this method by evaluating its impact on unit nonresponse, item nonresponse, and answer reliability. To do this, we analyze experimental data from a recent survey of male inmates incarcerated in a medium security, private prison.
Results
Findings indicate that the overall response rate is higher among inmates who are provided a survey choice. In addition, the evidence shows that the SSC method increases the percentage of individual items completed, the number of demanding questions completed, and the reliability of reported responses.
Conclusion
The results from the analyses are consistent with the hypotheses that motivated this study and suggest that the SSC method holds promise as a tool for correctional researchers. 相似文献
This article focuses on the transformatory potential of macroprudential ideas following the financial crash of 2008, examining how they are being mediated by existing institutional contexts and how and why the task of building a new body of technical macroprudential knowledge is proceeding slowly. It is argued that the movement toward a form of macroprudential regulation has a distinctly incremental dynamic that means any macroprudential transformation will be a gradual process that is likely to span a decade or more. Using Peter Hall's framework of three orders of policy change across substantive and temporal dimensions, the article argues that the macroprudential ideational shift can be compared to third order change. In this sense, it was intellectually radical and took place rapidly in a period of around six months. However, intellectual radicalism does not automatically translate into a radical change in regulatory practice, because of a variety of countervailing political, institutional, and informational variables. In this respect, the task of developing first and second order macroprudential policy is proving to be a much more politically contested process. Furthermore, macroprudential policy is being developed by cautious technocrats who rely on the gradual accumulation of data and evidence to justify policy. The result is a distinctly incremental dynamic to macroprudential policy development that displays many of the features of a process that historical institutionalists refer to as “layering.” 相似文献

Accountability has been identified as one of the most serious issues in the new democracies. Typically, assessments of the strength of democratic accountability in Africa rarely go beyond the elected and their election. This article argues that an examination of accountability needs to be widened to include all who make decisions that affect the community leaving them with no effective choice, whether they are elected to do so as representatives, or do so in a private capacity as power holders. The reasons are theoretical, empirical and pragmatic. Though the argument is primarily concerned with considering where the limits of the democratic ideal should be fixed, some examples are given of the gap between democratic ideals and actually existing democracy in sub‐Saharan Africa. They reveal a wide variation and contradictions in the actual practice of accountability, so reinforcing the point that attempts to assess the measure of accountability must be multi‐dimensional. 相似文献
Commonwealth policing, since its turbulent emergence in Australia in 1917, has shown both a keen capacity to suppress dissent and a remarkable ability to reinvent itself in a variety of forms. Its present nomenclature of the Australian Federal Police (AFP) arose from an alleged terrorist incident: the 1978 Sydney Hilton bombing.
This article argues that the fragmented AFP faced an ill‐defined and uncertain future in the early 1990s. Since September 11, the revamped AFP, however, has claimed primacy as Australia's leading law enforcement agency, but remains susceptible to government pressure. Contemporary Australian debate has focused on intelligence agency legislation, but limited analysis has addressed the AFP's changing role, expanded powers and significantly increased budgetary resources. As terrorism, national security and people smuggling have become the new “law and order'’ federal agenda, the AFP, straining to accomplish both domestic and regional functions, has extended its transnational, off‐shore policing strategies and intervention. 相似文献
This article examines the policing of a major international political event (the G20 Meetings in Brisbane, Australia in 2014) from the perspective of the police and representatives of demonstrator groups who participated in the event. The article locates the policing of the 2014 G20 meetings within the history of the policing of major international political meetings in other countries. It analyses the legal framework within which the policing of the Brisbane G20 meeting was undertaken, comparing and contrasting these with legal frameworks developed for similar meetings and associated demonstrations in other jurisdictions. In the case of the Australian G20 Act, the legislation prioritized security over human rights, including the freedoms of expression and peaceful assembly. The strategies and planning processes applied by police in the lead up to the G20 are discussed, including the efforts made to ensure policing responses were respectful of the democratic rights of protesters. Drawing on interview and other data, the article reveals a diversity of perspectives on the ‘human rights’ policing and dialogue models, and provides an assessment of ‘Operation Southern Cross’ based on the post-event review of the G20 legislation undertaken by the Queensland Crime and Corruption Commission. The authors conclude that the policing of G20, based on extensive dialogue and minimization of coercive public order strategies, fostered a peaceful G20 event. The article concludes with observations about the perceived success of G20 policing in Australia, and indicates some lessons learned for best practice policing for future global events. 相似文献
The purpose of this study was to compare blood fentanyl concentrations in fentanyl-related deaths with fentanyl concentrations found incidentally at autopsy, as well as with fentanyl concentrations found in hospitalized patients receiving fentanyl. Between the years 1997 to 2005, 23 fentanyl-positive postmortem cases were identified. Nineteen of 23 (82.6%) cases were deemed to be drug overdoses. Fentanyl alone was responsible for 8 of the 19 (42.1%) overdose deaths. Mean and median fentanyl concentrations were 36 (SD 38) microg/L and 22 microg/L, respectively, range 5-120 microg/L. Seven of the cases were accidental, one undetermined. The remaining 11 of the 19 (57.9%) cases were mixed drug overdoses. Fentanyl concentrations in these cases were 31 (SD 46) microg/L, range 5-152 microg/L. All of the mixed drug overdoses were determined to be accidental. Four cases where fentanyl was considered an incidental postmortem finding were determined to be natural deaths. In hospitalized inpatients (n = 11) receiving fentanyl 2 of the patients receiving fentanyl for chronic pain for more than 3 months had concentrations of 8.5 microg/L and 9.9 microg/L. The other nine inpatient concentrations were less than 4 microg/L. In conclusion, blood fentanyl concentrations found in cases where fentanyl alone was determined to be the cause of death were similar to cases where fentanyl was part of a mixed drug overdose. There was also considerable overlap between fentanyl concentrations in fentanyl-related overdose deaths compared to hospitalized patients being treated for chronic pain. Fentanyl concentrations in postmortem cases must be interpreted in the context of the deceased's past medical history and autopsy findings. 相似文献
