Cold case squads have garnered much attention; however, they have yet to undergo significant empirical scrutiny. In the present study, the authors interviewed investigators and reviewed 189 solved and unsolved cold cases in Washington, D.C., to determine whether there are factors that can predict cold case solvability. In the interviews, new information from witnesses or information from new witnesses was cited as the most prevalent reason for case clearance. The case reviews determined that there were factors in each of the following domains that predicted whether cases would be solved during cold case investigations: Crime Context, Initial Investigation Results, Basis for Opening Cold Case, and Cold Case Investigator Actions. The results suggest that it is possible to prioritize cold case work based on the likelihood of investigations leading to clearances.  相似文献

Fiscal, administrative, and political tensions among the partners in the federal system have not eased, and perhaps have grown, since the demise of the U.S. Advisory Commission on Intergovernmental Relations in 1996. Yet no governmental organizational capacity exists to address big intergovernmental questions in an ongoing manner through nonpartisan or bipartisan research, data collection, deliberation, and policy formulation.  相似文献

Gerasimov's plastic facial reconstruction method is notoriously difficult to repeat from the published literature. Primarily, this is because of the method's underlying qualitative basis but other factors contribute including: misreports in the secondary literature of Gerasimov's method essence; a lack of published details concerning Gerasimov's modeling mastic; Gerasimov's deviation from his own published nose projection prediction guidelines; and continued refinement of the methods in the 15 years following their foremost publication. As Gerasimov cannot be consulted to resolve these issues, we provide solutions via one of his five former principal students. This includes clarification of Gerasimov's method and use of soft tissue depths; the constitution of his modeling mastic; methods used for nose projection prediction; and refinements made to his methods following their primary publication.  相似文献

The entry of gig-platforms to labor markets world-wide has caused significant frictions with national institutions and regulators, including trade unions. In this article, we compare the interactions between taxi and food delivery platforms with the industrial relations (IR) systems of Denmark and Sweden, where we observe isolated instances of unions striking collective agreements with platforms. We assess and compare platform strategies and interactions with IR system agents, using an RIT-framework (rulemaker-intermediary-ruletaker) which considers how rulemaking capacity is allocated within the Nordic IR systems. We detect both IR system evasion and integration in Denmark and Sweden, with significant variation in causes and mechanisms. We find that IR system integration can be explained by public backlash, pressure from IR system insiders, and gaining first-mover advantages. Our findings shed light on integrative mechanisms of the Nordic IR systems allowing us to identify and discuss future challenges posed by the platform economy.  相似文献
