Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P1 through P8] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P1, P2, P4, P5, and P8 can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles. 相似文献
This study was an attempt to replicate the findings from an earlier experimental evaluation of a probation officer training program by Bonta et al. (Criminal Justice and Behavior, 38: 1127–1148, 2011). An experimental design was used with an improvement in the random assignment of clients and was tested with a sample of probation officers from a new jurisdiction.
Methods
Probation officers from the Canadian province of Alberta were randomly assigned to training or probation-as-usual. Officer behavior was measured by audio recordings of supervision sessions and recidivism was defined as a new conviction within 2 years of the initial recording. Attrition resulted in 27 probation officers submitting audio recordings of supervision sessions over a 6-month period (15 in the experimental group and 12 in the control). There were 160 recordings of 81 probationers submitted.
Results
The audio recordings showed inconsistent changes in officer behavior and no differences in recidivism between the clients of the experimental and control probation officers. However, the use of cognitive techniques by the probation officers was associated with a longer time to recidivism. In addition, by 10 months, more than half of the trained officers stopped their involvement in ongoing professional development activities.
Conclusion
Although the study failed to replicate the major findings reported by Bonta et al., it did highlight the importance of cognitive techniques in officer training. The results are interpreted with respect to the replication literature and the difficulties inherent in direct and conceptual replications especially in real-world settings.
The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal. 相似文献
The EU has regulated chemicals since the late 1960s using both general and sectoral legislation, and exposure-based, hazard-based and risk-based decisions. A new proposal from the European Commission – on the Registration, Evaluation and Authorization of Chemicals (REACH) – will build on the experiences of the existing legislation and introduce some new concepts in the management of chemicals. This article is aimed at assessing the current chemical control mechanisms in the EU and those put forward in REACH to demonstrate how REACH is a new paradigm in chemicals management. REACH will carry forward today's experience and approach to the management of chemicals in the EU and introduces some novel aspects, such as utilizing market-based mechanisms and putting into operation the 'substitution principle'. 相似文献
In 1970, the Congress enacted the Organized Crime Control Act. Title IX of the 1970 Act is the Racketeer Influence and Corrupt
Organization Act or RICO. This Act had its origins in legislation going back as far as 1934, but coming forward to 1961. The
1970 Act borrowed ideas from this earlier legislation, principally “enterprise,” but also the use predicate statutes to define
“racketeering activity.” The ideas are not new, but their combination affects how prosecutors and law enforcement agents investigate,
try, and sanction violations of the Act. RICO’s drafting also reflects organizational theory and economic analysis. The investigation
and prosecution of a single crime committed by an individual on a single day and in a single place maybe done using one set
of procedural and evidentiary rules. Nevertheless, the investigation and prosecution of patterns of diverse offenses committed
by, through, and against licit and illicit enterprises require sophisticated procedures, evidentiary rules, and criminal sanctions.
In addition, antisocial conduct is more than a challenge to the administration of criminal justice; it also requires the full
panoply of civil sanctions, including public injunctions as well private enforcement of injunctive relief and treble damages.
RICO has had a profound effect on the prosecution of organized crime, white-collar crime, and other forms of similar criminal
behavior.
