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.     

Managing commercial risks in open source software licensing

Legal context: The article reviews the commercial risk allocation clauses intypical open source licence terms and discusses their enforceabilityand implications. Key points: The enforceability of warranty disclaimers and limitation ofliability clauses in common open source licence terms is questionable,particularly in a cross-border context, and commercial licensorsshould take additional steps to protect themselves from down-streamrisks. Practical significance: Open source software presents a number of unusual commercialissues, because it is available free of charge and the providerstry to disclaim warranties and liabilities. End users and resellershave to adjust their own in- and out-licensing models to accommodatethis situation.

Quality Management in Public-Sector Organizations: Evidence from Six EU Countries

Although there is considerable evidence for the hypothesis that an efficient use of management techniques is the key to a good public service delivery, a lot of studies come to the conclusion that there is only partial, reluctant implementation or even a general lack of the use of such techniques by public managers. This paper examines the determinants for the use of quality management techniques in public sector organizations from six EU countries. It turns out that especially more organizational autonomy and result control appear to be of importance while, surprisingly, the combination of these variables leads to negative results.     

Raising citizens in ‘mixed’ family setting: mothering techniques of Filipino and Thai migrants in Belgium

As states increasingly regulate ‘mixed’ family formation, self-positioning has become central to the lives of migrant spouses, including women. To understand this process, the present article investigates the mothering techniques of Filipino and Thai migrant women in Belgium, that is, the decisions, actions and ways of being they consciously enact in response to state policies ‘here’ and/or 'there' to secure the mother–child bond in space and time. Interviews and observations reveal these women’s main techniques: obtaining Belgian nationality for themselves, prioritising a single nationality (Belgian) for their children and staying at home (in the case of Filipino migrant women) or working (in the case of Thai women). This self-positioning sets these women’s own path and prepare their children’s route towards full, active membership in the nation. Mothering appears therefore as a fertile site of citizenship, which from afar echoes the public–private divide but in close-up reveals the porosity of such dichotomy.     

马来西亚饮食业的命名研究——以中文招牌为例

文章对槟城、雪兰莪、马六甲、柔佛、砂拉越及吉隆坡的1241个饮食业中文招牌样本进行调查分析,发现它们有独特的典型基本结构,而且以"专名项+业名项+通名项"为主。文章也罗列了马来西亚饮食业中文招牌普遍运用的18种命名法,其中4种是此研究中新发现的。研究结果除了可起到填补空缺及留下及时记录的作用,也对从事饮食业的人士有一定的参考价值。     

论现场勘验人员的安全防护

现场勘验人员的安全防护理应是现场勘查技术中现场保护的主要研究内容。长期以来,对现场保护的研究只是片面强调了对现场的保护,对现场上痕迹、物品及尸体的保护,而对现场勘验人员的安全防护却仅依靠其自身的生活与工作经验,或只是师徒传承等基础之上的自发、盲目的行为。目前,在现场勘验过程中的人员伤亡事故频频发生,教训屡见不鲜,使得现场勘验人员的安全防护成为现场保护薄弱、滞后的研究领域。现场勘验工作本身就是一个需要全体参与人员相互协作配合的团队工作,现场勘验人员的安全防护自然也概莫能外。
