Research with homelessness professionals (HPs) working in the UK voluntary sector shows that expert definitions of homelessness can either undermine or enhance the health of the homeless. Guided by the concepts of social representations and cognitive polyphasia, the analysis reveals a contradictory field of knowledge, which reflects the struggle of professionals to sustain a humanizing approach and resist the pressures of statutory agendas. We conclude pointing to the need of recognizing the impact of professional's knowledge on the health and care policies for the homeless.<\/jats:p>","DOI":"10.1177\/1359105307080611","type":"journal-article","created":{"date-parts":[[2007,9,12]],"date-time":"2007-09-12T07:58:39Z","timestamp":1189583919000},"page":"779-790","source":"Crossref","is-referenced-by-count":35,"title":["Expert Knowledge, Cognitive Polyphasia and Health"],"prefix":"10.1177","volume":"12","author":[{"given":"Alicia","family":"Renedo","sequence":"first","affiliation":[{"name":"London School of Economics, UK,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Jovchelovitch","sequence":"additional","affiliation":[{"name":"London School of Economics, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2007,9,1]]},"reference":[{"key":"atypb1","volume-title":"Meeting the needs of homeless people with multiple problems","author":"Aldridge, R.","year":"1997"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.5749\/j.ctt22727z1"},{"key":"atypb3","volume-title":"A literature review on access to mainstream public services for homeless people","author":"Cesi.","year":"2005"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1002\/casp.717"},{"key":"atypb5","volume-title":"Single homeless people in London: Profiles of service user and perceptions of needs","author":"Crane, M.","year":"2001"},{"key":"atypb6","volume-title":"From the margins to the mainstream A new model of public service delivery","author":"Crisis.","year":"2005"},{"key":"atypb7","volume-title":"Statistics about homelessness","author":"Crisis.","year":"2006"},{"key":"atypb8","volume-title":"Guide to models of delivering health services to homeless people: Crisis health action","author":"Gorton, S.","year":"2003"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-349-23535-3"},{"key":"atypb10","unstructured":"Jacobs, K.                 ,                      Kemeny, J. &                      Manzi, T.
