Background: Culturally, hearing children born to Deaf parents may have to mediate two different positions within the hearing and Deaf cultures. However, there appears to be little written about the experiences of hearing children born to Deaf parents in the South African context.Objective: This study sought to investigate the roles of children of Deaf adults (CODAs) as interpreters in Deaf-parented families, more specifically, the influence of gender and birth order in language brokering.Method: Two male and eight female participants between the ages of 21 and 40 years were recruited through purposive and snowball sampling strategies. A qualitative design was employed and data were collected using a semi-structured, open-ended interview format. Themes which emerged were analysed using thematic analysis.Results: The findings indicated that there was no formal assignment of the interpreter role; however, female children tended to assume the role of interpreter more often than the male children. Also, it appeared as though the older children shifted the responsibility for interpreting to younger siblings. The participants in this study indicated that they interpreted in situations where they felt they were not developmentally or emotionally ready, or in situations which they felt were better suited for older siblings or for siblings of another gender.Conclusion: This study highlights a need for the formalisation of interpreting services for Deaf people in South Africa in the form of professional interpreters rather than the reliance on hearing children as interpreters in order to mediate between Deaf and hearing cultures.

Multiple studies have noted the impacts on student mental health of the COVID-19 pandemic, associated national lockdowns and emergency remote teaching. In light of COVID-19 shifting from pandemic to endemic status, this study investigates the developmental and mental health consequences of the pandemic for a group of South African undergraduate students. A qualitative design allowed for the thematic analysis of the narratives of 140 humanities students, gathered through an online survey. This paper presents the 'voices' of this group to convey the intensity of their COVID-19 experience. The results suggest a loss of a sense of freedom and opportunities to explore and experiment, high levels of depression with a notable sense of hopelessness regarding the future and decreased motivation, and significant reports of social anxiety related to delays in the development of social skills due to social isolation, particular to the first-year cohort.
The Brazil nut tree (Bertholletia excelsa) is an iconic and economically valuable species that dominates vast swathes of the Amazon Basin. This species seems to have been an important part of human subsistence strategies in the region from at least the Early Holocene, and its current distribution may be a legacy of past human settlement. Because B. excelsa is a long-lived pioneer tree it requires natural or human disturbances to increase light availability in the understory for a successful establishment. However, it remains unclear how the long-term population dynamics of this species have been shaped by pre-colonial and post-colonial human practices. Here, we use tree-ring analyses to look at changes in growing conditions over the past 400 years in a Brazil nut tree population in Central Amazonia. We identify changes in tree recruitment and growth rates associated not only with regional climatic variability, but also major political and socio-economic activities recorded by historical documents in the vicinity of Manaus. We demonstrate that the expansion of a post-colonial political center (Manaus) from the middle of the 18 th century onwards coincided with a reduction in recruitment of B. excelsa. We argue that this hiatus suggests the interruption of indigenous management practices, probably due to the collapse of pre-Columbian societies. A second recruitment pulse, and unprecedented cycles of growth release and suppression, aligns with a shift to modern exploitation of the forest into the 20 th century. Our findings shed light on how past histories of human-forest interactions can be revealed by the growth rings of trees in Amazonia. Future interdisciplinary analysis of these trees should enable more detailed investigation of how human forest management has changed in this part of the world, through pre-colonial, colonial, and industrial periods of human activity, with potential implications for conservation. © 2019 Caetano Andrade et al.

25 páginas, 6 figuras, 2 tablas ; Characterization of the genetic landscape of Alzheimer's disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/'proxy' AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly complex. We also built a new genetic risk score associated with the risk of future AD/dementia or progression from mild cognitive impairment to AD/dementia. The improvement in prediction led to a 1.6- to 1.9-fold increase in AD risk from the lowest to the highest decile, in addition to effects of age and the APOE ε4 allele. ; This work was funded by a grant (EADB) from the EU Joint Programme – Neurodegenerative Disease Research.
