The overall purpose of this thesis is two-fold; to illuminate the meaning of living with ‘impurity’ in terms of malodorous exuding ulcers, and the meaning of caring for people with ‘impure’ bodies in institutions and in people’s homes. The thesis comprises four papers based on studies using qualitative methods. To illuminate nursing care as narrated by 27 retired care providers in northern Sweden, seven audio recorded group dialogues were performed (I). The transcribed group dialogues were analysed using a hermeneutic approach. The findings formulated as cleanliness, order and clear conscience point to purity. By cleaning patients and their surroundings repeatedly, by preserving order in various ways and by keeping a clear conscience, nurses committed to preserving purity. This study opened up for questions concerning the meaning of ‘impurity’ and‘purity’ in nursing today leading to papers II-IV. Learning about ‘purity’ is possible through studying ‘impurity’. Audio recorded narrative interviews were performed to illuminate the meaning of living with malodorous exuding ulcers (II) and the meaning of caring for people with malodorous exuding ulcers (III). A phenomenological-hermeneutic method was used to analyse the nine transcribed interviews with patients (II) and 10 transcribed interviews with nurses (III). The comprehensive understanding of living with malodorous exuding ulcers (II) was formulated as being trapped in a debilitating process that slowly strikes one down. There is a longing for wholeness and purity. When finding consolation, i.e., encountering genuineness and feeling loved, regarded and respected as fully human despite ulcers, patients feel purified. The comprehensive understanding of caring for people with malodorous exuding ulcers (III) was formulated as being exposed to, and overwhelmed by suffering that is invading. One runs the risk of experiencing desolation when one cannot make the ulcers and malodour disappear and fails to protect patients from additional suffering. To illuminate nurses’ reflections on obstacles and possibilities providing care as desired by people with malodorous ulcers (IV), six nurses from a previous study (III) were interviewed. An illustration with findings from paper II was shown and participants were asked to reflect on obstacles and possibilities providing the care desired by patients. The 12 audio recorded transcribed interviews were analysed using qualitative content analyses. The interpretations were presented as one theme ‘striving to do ‘good’ and be good’. The sub-themes related to the obstacles were ‘experiencing clinical competence constraints’, ‘experiencing organisational constraints’, ‘experiencing ineffective communication’, ‘fearing failure’ and ‘experiencing powerlessness’. The sub themes related to possibilities were ‘spreading knowledge on ulcer treatments’, ‘considering wholeness’ and ‘creating clear channels of communication’. The meaning of living with ‘impurity’ in terms of malodorous exuding ulcers, and the meaning of caring for people with ‘impure’ bodies in institutions and in patients’ homes is interpreted as striving for purity. Patients experience impurity when feeling dirty, losing hope, and not being respected and regarded as fully human. Nurses experience impurity when failing to shield patients’ vulnerability and their own defencelessness, and when facing obstacles preventing them from providing good care and being good nurses. Both patients and nurses may experience purity through consolation. For nurses, mediating consolation presupposes being consoled by being recognised for their challenging work, being respected and included in multiprofessional teams supported by the health care organisation and the leaders. Then patients can become consoled, and feel restored and fully human again despite their contaminated body.

Over the last ten years, a newly created ritual called a Purity Ball has become increasingly popular in American evangelical communities. In much of the present literature, Purity Balls are assumed solely to address a daughter’s emerging sexuality in a ritual designed to counteract evolving American norms on sexuality; however, the ritual may carry additional latent sociological functions. While experienced explicitly by the individual participants as a celebration of father/daughter relationships and a means to address evolutionary sexual mating strategies, Purity Balls may implicitly regenerate existing social hierarchy. This ritual facilitates a sociological purpose by means of re-establishing the role of the male through halting the psychological development of sexual identity in the daughter, and these rituals are enacted in the ownership of the daughter by the father, who is responsible for maintaining the daughter’s purity, for “covering her with his protection.”

This thesis attempts to read Rebecca Walker's memoir Black White and Jewish as an investigation into the problematic of the social construct of race. It begins with an elaboration on the society's phobia about racial amalgamation owing to its potentiality to alter color boundaries, which are maintained through the manipulation of power. Born in a society where racial purity is highly postulated, Walker encounters an identity crisis that renders her double alienated and marginalized. What follows, thereby, is an examination of the identity formation of Walker as a mixed black and white individual, as well as a discussion of how racial hybridity may challenge essentialist racialization. With its fluidity and ambiguity, Walker's mixed race identity turns out to contest and further destabilize the immutability, stability, and homogeneity of essentializing racial categories. By cherishing the boundary-crossing capability a multiracial possesses, Walker could liberate herself from the shackles of the trauma of racism.

The central objective of this project is to chart the relationship between early-modern notions of race that developed in the Iberian-Atlantic world and systems of colonial racialization that emerged in the Americas in relation to mestizaje. By analyzing three case-studies from Latin American's early-colonial period, I show that as anxieties about racial mixture got intertwined with the Iberian notion of purity of blood, spatial segregation and the curtailment of interracial sex became two of the main issues around which early-colonial discourses on mestizaje were articulated. In chapter one, I justify the use of the term race for analyzing this period by drawing from current scholarship whose aim is to historicize this notion as a means to better theorize it. Moreover, I explain the specific elements that inform the theory of race that I develop throughout this project, including Bernasconi's formulation of race as a border concept, JanMohamed's notion of racialized sexuality, and Foucault's account of how biopower can help us theorize the interconnections between race and reproductive sex. In the second chapter, I examine Vasco de Quiroga's decisive influence in the formation of the Dual Republic model of spatial segregation in Mexico, and I show how the racialization of space during this period led to a dualistic conception of society that by definition left no place for the liminal figure of the mestizo. In chapter three, I examine a policy adapted by the Portuguese Crown during the sixteenth century whereby white Portuguese women were taken to Brazil in an effort to reduce interracial sex and miscegenation. Lastly, in chapter four I analyze Felipe Guaman Poma de Ayala's abject characterization of mestizos in Peru, and I demonstrate that two of the key issues around which he organized his demand for colonial reforms were spatial segregation and the curtailment of interracial sex. By examining these three cases-studies comparatively, and further incorporating a transatlantic perspective that situates them within broader developments that were taking place during the early-modern period, I emphasize the importance that the study of colonial Latin America has for current efforts to historicize the notion of race.
