High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献

Although parental compliance with court orders in child welfare cases is key to achieving physical parent‐child reunification and successful case closure, little research has examined how parent‐child relationship‐focused rehabilitative services uniquely influence case outcomes. This project fills this gap by investigating links between court ordering of and parental participation in Child‐Parent Psychotherapy (CPP) with court outcomes. Data were obtained from court records of 448 court‐involved parents. Hierarchical regressions revealed that greater participation in CPP led to reunification and successful case closure but not faster case closure. Courtroom professionals should consider parent‐child relationship‐based therapies as tools for achieving child welfare goals. 相似文献

Prime Minister Koizumi’s six consecutive annual visits to Yasukuni shrine played a key role in initiating a new phase of domestic
citizen political mobilization not seen since the early 1970s. This paper is based on field research during the Koizumi years
(2001–2006) centering on domestic groups that conduct activities in “protection” of or “opposition” to Yasukuni shrine. As
a study of street-based politics, this paper seeks to uncover the processes, strategies, and outcomes of citizen responses
to elite political action at Yasukuni Shrine as well as explore meaning of their actions within the context of Japan’s democratic
polity.

His doctoral dissertation, entitled ‘Democracy and Yasukuni: Citizen Reaction to political action at Yasukuni Shrine, 2001–2006’ has served as the basis for conference presentations on Yasukuni and its attendant controversies. 相似文献
