Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year. 相似文献

Public administration scholarship on race and gender is motivated by normative concerns about social equity, and dominated by work on bureaucracy and its representativeness. Despite decades of research on race and gender in public administration, there has been limited engagement with racializing and gendering processes. Relatedly, scant attention is paid to other disciplines that center on race and gender in theorizing. The purpose of this review is to explore public administration scholarship on race and gender in the context of allied social science disciplines, reveal limits of current approaches in public administration, and articulate strategies for enhancing understanding of race and gender in public administration scholarship. We use bibliometric and content analysis methods to map the intellectual structure of social science scholarship on race and gender, highlight public administration's place in this structure, and compare public administration scholarship on race and gender with other social science disciplines. 相似文献

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM. 相似文献

Policy support matters for the success of public policies. It is still unclear how governments can garner support for policies with high costs. Using a conjoint experiment in China, we demonstrate that governments can encourage policy support by offering institutional services and material interests to policy targets. In particular, citizens become more willing to support policies when governments timely disclose policy information and respond to and incorporate their voices in the policy design. Government subsidies in both the short and long runs also increase citizens' policy support. In addition, government transparency and long-run subsidies are complementary to enhancing policy support; the role of institutions is strengthened when citizens are exposed to severe policy problems. 相似文献

Recent years have seen an increase in the use of delegated legislation to implement major policy decisions in the UK. This has exacerbated the longstanding criticism that Westminster lacks sufficiently robust procedures for parliamentary scrutiny of delegated legislation. However, the UK is not the only country to use delegated legislation, or to face the challenge of ensuring it receives adequate parliamentary scrutiny. This article therefore places the UK system in wider context by comparing it to six other national parliaments. We highlight one comparative strength of the UK system, two weaknesses it shares with the other six cases, and one way in which the UK might learn lessons from elsewhere. Overall, our evidence suggests that no one country offers a clear template for more rigorous parliamentary scrutiny of delegated legislation. Successful reform of the UK's system is likely to require creative procedural innovation. 相似文献
