What is a 'domain'?

With visitors to the website confusing the title Hodges' Health Career Model for job careers; the addition of 'Care Domains' was intended to reduce confusion.

I think this has helped, but because the future beckons and this blog plus the website appear to have a multidisciplinary readership more clarity may be of help, especially the use of this word 'domain'.

The dictionary is a good place to start:

do·main

1. A territory over which rule or control is exercised.
2. A sphere of activity, concern, or function; a field: the domain of history. See synonyms at field.
3. Physics. Any of numerous contiguous regions in a ferromagnetic material in which the direction of spontaneous magnetization is uniform and different from that in neighboring regions.
4. Law.
a) The land of one with paramount title and absolute ownership.
b) Public domain.
5. Mathematics.
a) The set of all possible values of an independent variable of a function.
b) An open connected set that contains at least one point.
6. Biology. Any of three primary divisions of living systems, consisting of the eukaryotes, bacteria, and archaea, that rank above a kingdom in taxonomic systems that are based on similarities of DNA sequences.
7. Computer Science. A group of networked computers that share a common communications address.

1. A territory over which rule or control is exercised: can apply in Hodges' model from a theoretic perspective by a curriculum, a scheme of work, and consequently in practice. We refer to the clinical domain, medical domain or social domain. This latter usage overlaps with 2. we often speak of fields of study and practice.

Place (territory) is the vital ingredient here; specific wards, clinics, treatment centres and even community may be described as a domain of care. The way 'domain' is used in day-to-day language may vary markedly. On some occasions the domain in question may be at an even higher level: clinical domain versus management domain.

3. Is interesting because although they are not exactly magnetic, there are several polarities* at work in Hodges' model.

On the borders between Hodges' domains, what is the 'switch' (context, situation, person focus ...) that determines the placement and direction of care concepts: for example - humanistic or mechanistic?

Sticking with physics there are undoubtedly several chaotic attractors within the bounds of Hodges' model. From the behaviour of the heart to the role of psychosocial stress in risk of relapse. If several variables are linked chaotically, what risks are run if one or more domains (however defined) are deemed non-relevant or out of scope?

4. This legalistic definition of 'domain' also applies. Hodges' model is person-centred, but although focused on the individual the model acknowledges the need to reconcile the diametric opposition that is the law that prevails for the one [INTERPERSONAL] and the law, justice and systems of the many [SOCIAL] and [POLITICAL].

Hodges' model is also in the public 'domain' all that is needed is an acknowledgement.

The remaining definitions 5, 6 and 7 - maths, biology and computer science - are all connected.

More to follow.... Hope to return over the weekend...
*Will post about polarities, when I take a certain photo over in Manchester.
Just hope they don't pull it down before I get there! Bye for now...
