A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. Human fingerprints are detailed, nearly unique, difficult to alter, and durable over the life of an individual, making them suitable as long-term markers of human identity.

The concept was familiar in the pre- Islamic era, but became popularized in Ibn Khaldun 's Muqaddimah , in which it is described as the fundamental bond of human society and the basic motive force of history, pure only in its nomadic form. Ibn Khaldun describes asabiyya as the bond of cohesion among humans in a group-forming community.

Contemporary ideas and strategies of both 'risk' and 'power' are significant and dynamic influences in social theory and social action, and they can therefore be expected to have a substantial impact on the ways in which social work is constituted, practiced and evaluated. In this article, I shall articulate distinct conceptualisations and debates about each of these, before considering their inter-relationships and the implications of these for our thinking about what social work is, and what it should be. Firstly, I will consider social work's contested and problematic place within the broader welfare domain. It is recognised as being a form of activity which inhabits an ambiguous and uncertain position at the interface between the individual and the social, and between the marginalised and the mainstream.
