Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200. 相似文献

Energy transitions are fiercely contested. The incumbents of the fossil‐ and nuclear‐based energy systems have much to lose from a transition to a sustainable and decentralized energy system. They therefore employ their material and political resources to reverse, halt, or slow down this transition. They also attempt to stop and reverse the decentralization of energy production. This article provides a framework that can be used to analyze the contestation that surrounds energy transitions. The analytical framework breaks apart the macro paths of energy transitions, and differentiates between three meso‐paths (political, economic‐technological, and legitimation), emphasizes the feedback processes between these paths, and acknowledges the crucial role that actors play in engendering these feedback processes. It uses Germany as a case study to illustrate the analytical model. It also provides hypotheses that will be tested in the subsequent contributions to this special issue. 相似文献

This thesis analyzed the cross‐section data of 630 non‐financial listed enterprises and adopts a logit model to estimate the relationships between political relations and corporate environmental behavior. The paper also adopts an ordered logit method to estimate the marginal impact of political connections to enterprises’ disclosure of information on environment and sustainable development. Through analysis, this thesis found that political connections lower the probability for enterprises to disclose information on environment and sustainable development. With the Level III scoring method, this article classified the performances of disclosing corporate environmental information into three levels. It is found that corporate political connections increase the probability for enterprises not to disclose any environmental information and lower the probability for enterprises to refer to GRI Sustainability Reporting Guidelines. 相似文献

This article focuses on the degree of policy congruence, and by extension policy responsiveness, of U.S. federal‐ and state‐level GMO labeling laws from 2011–2016. Utilizing consumer survey data, evidence overwhelmingly demonstrates consumers prefer clear text‐based indication if food products contain genetically modified ingredients. However, the federal law adopted in 2016 mandates GMO labeling but with exceptions permitted to clear on‐package text labeling. The results of this study demonstrate that consumer preferences were not adequately represented at the federal level and were misaligned with state policy activities as captured in the aggregate outcome. State legislatures were actively proposing mandatory legislation with only a few cases of success, which did not adequately represent the wishes of the people. Given the misalignment and overall policy incongruence, the consequences of pending federal law are discussed in light of why the voices of the consumer choir were not heard by lawmakers. 相似文献

Our article explores the contribution of local initiatives to the creation of path dependencies for energy transition in Germany and Japan in the face of resistance from entrenched incumbents at the national level. We use a process‐tracing methodology based partly on interviews with local participants. In particular, we explore the role of local initiatives in securing “socio‐political space” for the expansion of renewable energy (RE) and in embedding themselves in “ecosystems” of public and private institutions. German energy activists were more successful than their Japanese counterparts in expanding this space and creating positive feedback in part because they were able to build horizontal networks that anchored the energy transition firmly in local communities. Although problems with grid technology have led to retrenchment in both cases, Japanese activists' reliance on vertical networks has limited their ability to weather a backlash from national government and utility actors. Our study demonstrates the interaction of political, economic/technological, and legitimation paths to energy transition and highlights the importance of the latter two. 相似文献

Abstract: Optimization of a light emitting diode (LED)-based excitation system for the detection of pretreated fingerprint fluorescence is described. Fluorescent ridges can usually be excited by irradiation with forensic light sources such as xenon arc lamps or quartz-halogen lamps with high-power output and suitable filters. However, they are too expensive for many crime laboratories in smaller organizations. We concentrated on LEDs which have advantages over conventional light sources in that they are simpler and of lower cost, but the power output and quality of each individual LED unit is not sufficient for the detection of weak fluorescent ridges. To resolve this subject, blue and green LED arrays composed of ninety LED units were adopted and suitable low pass filters for them were designed. An experimental system, consisting of blue and green LED arrays with the suitable low pass filters for illumination, high pass filters for viewing, a digital camera and a computer, was tested. The fluorescent images of cyanoacrylate ester fumed/rhodamine 6G stained fingerprint on white polyethylene sheet and weak fluorescent ridges of ninhydrin/indium chloride treated fingerprint on white paper were successfully detected and photographed. It was shown that the improvement of LED beam in intensity and quality can compensate the disadvantages, resulting in well-contrasted images. 相似文献

Der Beitrag besch?ftigt sich mit jener Rolle, die der Rechtsprechung bezüglich der Weiterentwicklung des ?sterreichischen
Wohnrechts zukommt. Er zeigt ua die praktische Bedeutung auf, die der richterlichen Rechtsanwendung und Rechtsfortbildung
in diesem Bereich zukommt, thematisiert die Frage, ob es in der wohnrechtlichen Rechtsprechung zu "Grenzverwischungen" zwischen
Rechtsanwendung und Rechtspolitik kommt und analysiert charakteristische St?rken und Schw?chen von richterlicher Rechtsfortbildung
im Wohnrecht. 相似文献
