False-negative probability in the SEM/EDS automated discovery of iGSR particles: A Bayesian approach
Martín A. Onetto MSc Edgardo Carignano BA Rodolfo G. Pregliasco PhD 《Journal of forensic sciences》2023,68(5):1792-1799
The automated search software integrated with a scanning electron microscope (SEM/EDS) has been the standard tool for detecting inorganic gunshot residues (iGSR) for several decades. The detection of these particles depends on various factors such as collection, preservation, contamination with organic matter, and the method for sample analysis. This article focuses on the influence of equipment resolution setup on the backscattered electron images of the sample. The pixel size of these images plays a crucial role in determining the detectability of iGSR particles, especially those with sizes close to the pixel size. In this study, we calculated the probability of missing all characteristic iGSR particles in a sample using an SEM/EDS automated search and how it depends on the image pixel resolution setup. We developed and validated an iGSR particle detection model that links particle size with equipment registers and applied it to 320 samples analyzed by a forensic science laboratory. Our results show that the probability of missing all characteristic iGSR particles due to their size is below 5% for pixel sizes below 0.32 μm2. These findings indicate that pixel sizes as large as twice the one commonly used in laboratory casework, that is, 0.16 μm2, are effective for initial sample scanning, yielding good detection rates of characteristic particles that could exponentially reduce laboratory workload. 相似文献

Czech politics suffers from a low durability of most of its governments, and frequent government crises. One of the products of this situation has been the phenomenon of caretaker governments. This article analyses why political elites have resorted to this solution, and discusses how this has reflected an older Czech tradition. Two cases of such governments are analysed in detail. The To?ovský government was characterised by the ability of the Czech president to advance his agenda through this government at a time when the party elites were divided. The Fischer government was characterised by the considerably higher role of parties that shaped and limited the agenda of the cabinet, and the president played a more static role. 相似文献

Counter‐knowledge refers to flaws in citizens' mental models arising from utilization of rumours, inappropriate knowledge structures, outdated routines or procedures. When counter‐knowledge is applied to civil servants, it may result in problems of efficiency, equity and motivation. This paper examines the relationship between counter‐knowledge and open‐mindedness to model a framework for improving city marketing and policy development. This study tested two measurement models. While the theoretical model represents the effect of counter‐knowledge on city marketing and that the latter has a negative effect on open‐mindedness, the alternative model involves that counter‐knowledge has a positive indirect impact on open‐mindedness. These relationships are examined through an empirical investigation of 203 Spanish city halls. The results show a potential positive indirect effect of counter‐knowledge on open‐mindedness through city marketing programmes. This paper clarifies the existing literature, which tries to contribute to the discussion of city marketing, and helps us to obtain meaning out of the relationship between counter‐knowledge, city marketing and open‐mindedness.
