In contrast, the homeless experience, according to Moore, constitutes more as a "lack of belonging" and a loss of identity that leads to individuals or communities feeling "out of place" once they can no longer call a place of their own home.This new perspective on homelessness sheds light on the plight of refugees, a population of stateless people who are not normally included in the mainstream definition of homelessness. It has also created problems for researchers because the nature of "counting" homeless people across the globe relies heavily on who is considered a homeless person. Homeless individuals, and by extension refugees, can be seen as lacking lack the "crucible of our modern society" and lacking a way of actively belonging to and engaging with their respective communities or cultures. As Casavant demonstrates, a spectrum of definitions for homelessness, called the "continuum of homelessness", should refer to refugees as homeless individuals because they not only lose their home, but they are also afflicted with a myriad of problems that parallel those affecting the domestic homeless, such as "[a lack of] stable, safe and healthy housing, an extremely low income, adverse discrimination in access to services, with problems of mental health, alcohol, and drug abuse or social disorganization". Refugees, like the domestic homeless, lose their source of identity and way of connecting with their culture for an indefinite period of time.
Osteonecrosis of the jaws refers to the death of bone marrow in the maxilla or the mandible due to inadequate blood supply. It is not necessarily a painful condition, typically there will be no pain at all unless bone necrotic bone becomes exposed to the mouth or through the facial skin, and even then this continues to be painless in some cases. When pain does occur, it is variable in severity, and may be neuralgiform or neuropathic in nature. The term NICO is used to describe pain caused by ischemic osteonecrosis of the jaws, where degenerative extracellular cystic spaces (cavitations inside the bone) are said to develop as a result of ischemia and infarctions in the bone marrow, possibly in relation to other factors such as a hereditary predisposition for thrombus formation within blood vessels, chronic low-grade dental infections and the use of vasoconstrictors in local anesthetics during dental procedures. This proposed phenomenon has been postulated to be the cause of pain in some patients with AFP or trigeminal neuralgia, but this is controversial. NICO is said to be significantly more common in females, and the lesions may or may not be visible on radiographs. When they are visible, the appearance is very variable. About 60% of the lesions appear as a "hot spot" on an technetium 99 bone scan.
