An archive of 5 years of cases involving the identification of human remains was curated, collecting information on: The sample type submitted, the number of STR loci yielding interpretable results, the kinship challenge posed, and the outcome for the case. A total of 129 cases of remains ID were investigated using manual DNA extraction and recovery methods with amplification of STR markers using the Power Plex 21 multiplex STR kit from Promega Corp. In 52 cases, blood spots collected by the ME were provided as sample and in 100% of those cases, probabilities of relatedness to the reference samples was ≥99%. In 77 cases, tissue other than blood was provided as a source of DNA. These other samples were grouped categorically into long bones (femur and tibia; 40 cases), skull bones/teeth (11 cases), other bones (16 cases), and tissue (normally adherent to bone) (10 cases). Reference samples provided for cases included alleged parents or child(ren) of the victim (86 cases), alleged full siblings of the victim (38 cases), or alleged second-order relatives (five cases). The overall success rate in confirming the identity of the source of the remains in these cases was 89.2%. Our results demonstrate that a laboratory can be often successful identifying human remains using methods easily implemented in any DNA typing laboratory.  相似文献

The institutional landscape for public land management in the U.S. West underwent a seismic shift in the 1990s as the long‐dominant resource extraction paradigm was replaced by the ecosystem management paradigm. Here we analyze the efforts of community‐based organizations (CBOs), entities that emerged in some locations across the West to help their respective communities navigate the transition from resource extraction to environmental stewardship. Despite their formal status as civil society actors, in practice CBOs came to fill various institutional gaps by taking on roles traditionally assigned to both the state and the private sector. We use a case study approach to examine how the Hayfork, California–based Watershed Research and Training Center engages in institutional work within a setting that is at once both open and constrained, as the rural community within which it operates lacks strong state‐ or industry‐led development trajectories while remaining constrained by the legacies of past institutions.  相似文献

Many scholars have argued that social programs are marked by a logic of “increasing returns” that makes change difficult. Yet over the past decades, reformers across industrialized countries have introduced substantial administrative reforms in these services, even as entitlement reform remains politically difficult. This paper explains these shifts by breaking apart the logic of “increasing returns” into three distinct “costs to change”: technical, political, and expectations. Decreases in a particular type of costs produce different logics of institutional change—back end, informal, and front end—that privilege the state, professionals or private, or political actors in distinct ways. I support these claims by reexamining three cases that were considered exemplars of stability but that ultimately had major entitlement reform: health care in the United Kingdom and United States and welfare programs in the United States. I show that even before radical reforms occurred, reformers introduced distinct logics of administrative change that underpinned later changes.  相似文献
