A mixed DNA profile controversy revisited

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.     

Child Sexual Abuse Perpetrated by Women: Case Series and Review of the Literature

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers.     

Countering Punitiveness: Understanding Stability in Canada's Imprisonment Rate

Canada's imprisonment rate has not changed appreciably since 1960. This stability contrasts with the increased imprisonment rates experienced by Canada's most obvious comparators—the United States and England and Wales. We examine this divergence and propose several interrelated explanations for Canada's anomalous pattern. While Canada is shown not to be immune to pressure for harsher practices and policies, it has been able to counter or balance these trends with other more moderating forces. In particular, we suggest that Canadians have largely been able to escape several of the wider forces or "risk factors" at the root of higher incarceration in other countries. Further, we suggest that certain protective factors of a historical, cultural, and structural nature can also be identified that have limited the extent to which Canada has adopted the same punitive policies documented in the United States and England and Wales.     

俄罗斯生态犯罪的立法评析及借鉴

俄罗斯刑法通过生态犯罪的设立保护生态环境,俄罗斯生态犯罪立法的价值取向、范围及处罚方式等,值得中国刑法立法的借鉴。中国刑法应设立生态犯罪以取代传统环境犯罪;中国生态犯罪应将生态法益作为保护的必要要件,其立法范围也要予以拓展。     

对我国发展循环经济的思考

从20世纪80年代开始,我国用短短的20多年走完了发达国家上百年的历程。发展规模之大、速度之快世所罕见。但是,我们在发展中走的仍是传统发展之路,能源、资源消耗大,经济、社会效益低,特别是生态环境破坏严重、代价高昂。有关专家提出,靠传统的发展模式解决不了经济发展中面临的资源生产率问题,必须树立科学发展观,坚定地实施可持续发展战略,走循环经济发展之路。本文着力探讨解决经济增长与资源和生态环境之间的矛盾的出路———发展循环经济,并提出了相应的对策措施。
