| 词条 | Sequence determination |
| 释义 |
A sequence determination is a type of examination conducted by a forensic document examiner.[1] This type of forensic examination is done in an attempt to determine which of two events occurred first in the preparation of a document. Another term used for this type of examination is "sequence of intersections" since the evaluation requires intersection of physical materials on the document. Types
MethodsThe primary means of evaluation involves direct visual examination using microscopy and various lighting options. The intersection point may involve subtle deviations from the normal manner of deposition or production that can be observed on microscopic examination (e.g. extraneous ink deposits, skipping, misalignents, embossing, etc.). Lifting/casting technique (see below) have also been tested with some success. Intersections involving indentations may also be assessed using an electrostatic detection device to visualize latent indentations.
SignificanceThe underlying concept is that each of the sequences will produce a distinctive result that can be visualized or measured. In some instances, the results will be essentially conclusive with only one reasonable interpretation. In other situations, the results may be less definite in that the observed features may permit more than one interpretation of the original sequence. References1. ^ASTM Standard E444-09 (Standard Guide for Scope of Work of Forensic Document Examiners) indicates in section 4.2.1.4 that the work of a forensic document examiner includes "The establishment of the date, source, history, sequence of preparation, alterations or additions to documents, and relationships of documents".
