Analysis Of Change

In the paper results of investigations of triboelectrical effects, proceeding in nonlubricated contacts, observed as “friction microcurrents”, and also in lubricated contacts - as “generated potential difference” are presented. Analysis of change dynamics of “friction microcurrents” and “generated potential difference” is making it possible to direct observation in real time and estimate the character course of interaction of elements in frictional contact.

The Senses

This chapter assesses observational methods. What distinguishes observational methods, and particularly participant observation (PO), from other data-gathering methods is, among others, that it privileges direct observation over the use of instruments. This implies that the observation is likely to be holistic, in the sense of involving the five senses, rather than only one of the senses (typically sight). PO also privileges observation in real time over the retrospective observation of traces left by past activities (texts, pictures, filmed sequences). It allows one to observe discourses, practices, interactions, and context together rather than separately. It focuses on first-hand observation, as opposed to observation based on secondary sources (involving a mediator or third person). PO is sometimes accused of harbouring a naive belief in the scientific virtue of ‘gut feeling’.
