This study reveals the tactic of purification as a form of neo-colonial marginalisation present in contemporary development strategies on Indigenous lands. The research is based on my fieldwork study of exclusive tactics in a contemporary development conflict on Indigenous lands: the Arctic Railway project in Sápmi, in Northern Europe. The tactic of purification works through the selective use of opposites in excluding Indigeneity. On the one hand, 'pure' Indigeneity is an excuse for proponents of extractive development projects to exclude Indigenous knowledge and identities as 'too Indigenous' according to modern standards, denouncing them as 'backward', 'only culture', 'not profitable', or 'without knowledge'. Yet, simultaneously, a resemblance to profitable livelihood practices, beyond culture, the use of several knowledge systems, and multi-ethnicity in communities, is deemed 'too modern', therefore 'not pure enough', thus invalidating Indigeneity. Building on classification systems introduced during colonialism, settler societies employ purification as a tactic to deny Indigenous peoples their right to decolonisation projects, and strengthen their control of Indigenous lands. The purification tactic thereby enables the expansion of the modern-colonial capitalist world order. [ABSTRACT FROM AUTHOR]

Preeclampsia is related with elevated systolic blood pressure (SBP) in children. We studied if preeclampsia-exposed (PE) children develop alterations in heart rate variability (HRV) and if this is reflected in their blood pressure (BP), as well as overall associations with body size and composition, gestational and perinatal factors. We examined 182 PE (46 early-onset PE) and 85 unexposed (non-PE) children 8-12 yr after preeclampsia exposure. HRV monitoring was performed 5 min in supine followed by 5 min in standing position and compared with office, 24-h ambulatory, and central BPs in relation to body anthropometrics and composition, gestational, and perinatal data. There were no major differences in HRV between PE and non-PE children. HRV in supine position was strongly associated with office and ambulatory heart rates (HRs), and HR was independently associated with office BPs. However, HRV was not related with office or 24-h SBP and PP, nor with elevated SBP in PE compared with non-PE children [adjusted mean differences for office and 24-h SBP 4.8 (P < 0.001) and 2.5 mmHg (P = 0.049), respectively]. In supine position, high-frequency (HF) power [b, -0.04 (95% CI -0.06 to -0.01)], root mean square of successive differences in R-R intervals (rMSSD) [-0.015 (-0.028 to -0.002)], and the ratio of low-frequency (LF) to HF power [0.03 (0.01-0.04)] were independently associated with child fat mass. LF and HF power and rMSSD displayed independent inverse associations with child age. There were no significant associations between child HRV and gestational and perinatal factors. During prepuberty, the HRV in children with PE is similar to that in non-PE children. Elevated SBP following preeclampsia exposure is not related with HRV. Child adiposity could be related to decreased cardiac vagal tone. [ABSTRACT FROM AUTHOR]
