The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

Meta‐Governance of Partnerships for Sustainable Development: Actors' Perspectives from Kenya 下载免费PDF全文
The 2030 Agenda for Sustainable Development promotes multi‐stakeholder partnerships (MSPs) as a means of implementation while at the same time putting renewed focus on the need for national‐level ownership and implementation. Despite the fact that an ever growing body of literature on the merits and drawbacks of MSPs delineates several success conditions for partnerships, efforts to translate this knowledge into national‐level meta‐governance for MSPs remain marginal to date. This study outlines the benefits the literature alleges for such “meta‐governance” frameworks, before it uses a country‐level study with a series of stakeholder interviews to take a closer look at national‐level context conditions and lessons learned with regard to two water partnerships in Kenya. Our findings suggest that to date the existing meta‐governance for partnerships in Kenya is rather weak and fragmented. Yet respondents support the view that MSPs could benefit from such a framework, in particular regarding local ownership of MSPs and the potential to scale successful cases.

Policy Positions of Bureaucrats at the Front Lines: Are They Susceptible to Strategic Communication? 下载免费PDF全文
It is well established that bureaucrats’ implementation of policies is influenced by their own policy positions, that is, their attitudes toward the given policies. However, what affects the policy positions of bureaucrats? This article focuses on whether the policy positions of bureaucrats at the front lines of government are susceptible to frames and cues embedded in communication. Based on the notion that bureaucrats often adhere to certain professional norms when developing their attitudes toward policies, the authors hypothesize that communication frames and cues that align policies with such norms move bureaucrats’ policy positions in favor of the policy. Results of four studies in European and American settings among mid‐ and street‐level bureaucrats show support for the hypothesized effect. They also show that aligning policies with dimensions outside professional norms is ineffective, possibly even producing opposite effects. 相似文献
