This study developed a composite machine learning algorithm for attribution of materials of forensic interest (like ammonium nitrate) to original sources. k-nearest neighbor and random forest models were used for source elimination and classification, respectively, in a two-step, composite algorithm based on particle color, size/shape, and trace element concentration features. Novel approaches for simulation to supplement within-source reference features based on empirically measured multi-lot analyses, an improved hold-one-lot-out method for cross-validation, an assessment of the likelihood of the presence of a reference sample, fusion of the source probabilities from the respective classification models, and the calculation of metrics for assessing ensemble sourcing performance are described. Excellent sourcing predictions were obtained; the sourcing algorithm identified the correct source as the top choice 89% of the time, and the correct source was identified to be an average of 2.7 times more likely than the most likely incorrect source. 相似文献

Stab wounds were made in parenchymatous organs (e.g. liver, spleen, kidneys, lungs) using a variety of instruments. The shape of the resulting canal was investigated by X-ray analysis after introduction of an X-ray contrast medium. The best contrast was obtained using a contrast medium containing barium. The shape of the canal gave a direct representation of the outline of the instrument used. The width of the canal was however, always several millimeters smaller than the corresponding blade of the instrument. The position of the blade back in single-edged blades could be demonstrated with stronger contrast. 相似文献

Much attention has been paid to the nature of parent-adolescent relationships, with a frequent conclusion being that it is a time of marked disagreement between parents and their adolescents. However, other literature suggests that this time is not inherently conflictual. The purpose of this study was to examine agreement and disagreement between mothers, fathers, and adolescents on specific issues. Then, adolescent adjustment was assessed, and the degree to which it was a function of congruence with parents was examined. A modified version of the Issues Checklist was used to measure intrafamily agreement; the Revised Behavior Problem Checklist and the Harter Scale of Child's Actual Competence were completed by adolescents' social studies teachers to assess adolescent functioning. Relative to their parents, adolescents reported that they should make more decisions alone, while both mothers and fathers reported that decisions should be made jointly among all family members. Only father-adolescent congruence was found consistently to be related to adolescent functioning. Possible explanations for the present results and relevant issues pertaining to family agreement are discussed. 相似文献

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

Mit der Einführung einer Entgeltpflicht für die Entnahme von Wasser in Nordrhein-Westfalen ist der erlaubnisfreie wasserrechtliche Eigentümergebrauch in den Mittelpunkt des Interesses gerückt. Denn wer Wasser im Rahmen des Eigentümergebrauchs aus einem oberirdischen Gewässer entnimmt, ist von dieser Entgeltpflicht befreit. Der folgende Beitrag erläutert die im Zusammenhang mit der Gewinnung nichtenergetischer Rohstoffe insoweit relevanten Fragen.

Der Wald hat für uns ?konomische, ?kologische, soziale und kulturelle Bedeutung. Leider
ist in letzter Zeit die kulturelle Bedeutung im Vergleich zur ?kologischen Bedeutung ins politische
Abseits geraten. Nun will man das seit 1975 geltende Bundeswaldgesetz novellieren. Dabei sollte zur besseren
Berücksichtigung des Denkmalschutzes bei der Definition des Waldes klargestellt werden, dass Park-,
Garten- und Friedhofsanlagen kein Wald im Sinne des Bundeswaldgesetzes sind. Die Bedeutung des Waldbodens
als Archiv der Natur- und Kulturgeschichte muss betont werden. Nicht zuletzt wegen der angestrebten Eintragung
der Deutschen Buchenw?lder in die Liste des Erbes der Welt muss zum Ausdruck kommen, dass Deutschland
die europ?ischen und internationalen Bemühungen zum Erhalt des Kultur- und Naturerbes wie das
übereinkommen zum Schutz des Kultur- und Naturerbes der Welt von 1972 unterstützt. 相似文献
