There are two types of physical traces: erosion and accretion. Erosion refers to the wearing away, or removal, of material because of a physical activity (e.g., a worn foot path). On the other hand, accretion is the building up of material because of physical activity (e.g., a pile of garbage) (Palys & Atchison, 2014).
For example, paint can be transferred from one car to another in a collision or a hair can be left on a sweater in a physical assault. This evidence can be used to reconstruct an event or indicate that a person or thing was present.
Name at least two examples of content analysis research. Define primary and secondary sources, describe their differences, and provide an example of each. Define physical traces and compare them to material artifacts. Outline the differences between manifest content and latent content.
Physical traces include such things as worn paths across campus, the materials in a landfill or in someone’s trash can, indentations in furniture, or empty shelves in the grocery store. Examples of material artifacts include video games and video game equipment, sculptures, mementos left on gravestones, housing structures, flyers for an event ...
1 de may. de 2020 · 1. Introduction. The term “trace evidence” refers to physical evidence that is small and transfers as a result of interaction between objects and individuals [1]. These materials are often microscopic in size but can yield information about what may have occurred, where the sample may have come from, and how the materials may have transferred.

A criminal investigation requires the forensic scientist to search and to interpret vestiges of a criminal act that happened in the past.
8 de abr. de 2024 · The relative position and overlapping of physical traces can help reconstruct the chronology of events. A typical example are latent sole marks indicating entry and exit ways, as well as pathways within premises (see example in Fig. 7) [67].
