Becoming a Xhosa traditional healer : the calling, illness, conflict and belonging

CITATION: Van der Watt, A. S. J. et al. 2021. Becoming a Xhosa traditional healer : the calling, illness, conflict and belonging. South African Journal of Psychiatry, 27:a1528, doi:10.4102/sajpsychiatry.v27i0.1528.The original publication is available at https://sajp.org.zaBackground: Traditional healers (THs) are an important part of the healthcare system in sub-Saharan Africa. Understanding their training, experiences of becoming healers and their perceived roles in society is critical. Aim: This study aimed to explore the experience of becoming a TH, including accepting the calling, and sheds light on how the experience is conceptualised within the cultural and communitarian context of THs. Setting: This study was conducted amongst Xhosa THs in the Western Cape, South Africa. Methods: In-depth phenomenological interviews (n = 4) were conducted with Xhosa THs and analysed using Giorgi’s descriptive pre-transcendental Husserlian phenomenological analysis. Results: The experience of becoming a TH can be summarised in the context of three units of significance: (1) the gift of healing as an illness; (2) the experience of conflict (including with their families, the church and self-conflict); and (3) the experience of belonging. Familial conflict, specifically, was fuelled by the financial burden of becoming a TH and a lack of understanding of the process. Conclusion: To develop a workable model of collaboration in the future, it is crucial that mental healthcare providers develop a better understanding of the experiences of THs in becoming care providers. The findings highlight an appreciation of the challenging process of becoming a TH. Finally, further research and culturally appropriate psychoeducation can provide trainee THs and their family members with the skills and knowledge to support each other through a difficult process.https://sajp.org.za/index.php/sajp/article/view/1528Publisher's versio

Instances and connectors : issues for a second generation process language

This work is supported by UK EPSRC grants GR/L34433 and GR/L32699Over the past decade a variety of process languages have been defined, used and evaluated. It is now possible to consider second generation languages based on this experience. Rather than develop a second generation wish list this position paper explores two issues: instances and connectors. Instances relate to the relationship between a process model as a description and the, possibly multiple, enacting instances which are created from it. Connectors refers to the issue of concurrency control and achieving a higher level of abstraction in how parts of a model interact. We believe that these issues are key to developing systems which can effectively support business processes, and that they have not received sufficient attention within the process modelling community. Through exploring these issues we also illustrate our approach to designing a second generation process language.Postprin

Multi-trait genome-wide association study identifies new loci associated with optic disc parameters

A new avenue of mining published genome-wide association studies includes the joint analysis of related traits. The power of this approach depends on the genetic correlation of traits, which reflects the number of pleiotropic loci, i.e. genetic loci influencing multiple traits. Here, we applied new meta-analyses of optic nerve head (ONH) related traits implicated in primary open-angle glaucoma (POAG); intraocular pressure and central corneal thickness using Haplotype reference consortium imputations. We performed a multi-trait analysis of ONH parameters cup area, disc area and vertical cup-disc ratio. We uncover new variants; rs11158547 in PPP1R36-PLEKHG3 and rs1028727 near SERPINE3 at genome-wide significance that replicate in independent Asian cohorts imputed to 1000 Genomes. At this point, validation of these variants in POAG cohorts is hampered by the high degree of heterogeneity. Our results show that multi-trait analysis is a valid approach to identify novel pleiotropic variants for ONH

The order of the Hopf bundle on projective Stiefel manifolds

Abstract. The projective Stiefel manifold X n,k has a canonical line bundle ξ n,k , called the Hopf bundle. The order of cξ n,k , the complexification of ξ n,k , as an element of (the abelian group) K(X n,k ), has been determined i
