Abstract: A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of hydromedusae were recovered at generally low abundance, of which Euphysa aurata, Leuckartia octona and Proboscidactyla menoni were dominant. E. aurata and L. octona showed evidence of seasonality in abundance. The low diversity of the fauna was remarkable and it is hypothesized that this might be attributable in part to sedimentation from the Orange River, and in part to locally weak circulation and the wide extent of the continental shelf.

Abstract: A total of 24 species of euphausiid was collected during a survey along the South African south coast during January 1992. Communities over the Agulhas Bank were of low diversity and abundance and were dominated by Nycliphanes capensis. Those at the shelf-edge were of high diversity and abundance and were dominated by Euphausia recurI'll and Thysalloessa gregaria. Such high diversity may be maintained by vertical scgregation at night. Few species displayed obvious diel vertical migration, although N. capen sis may be able to maintain itself on the shelf by means of this behaviour. E. recurl'Cl appeared to feed on phytoplankton throughout the water column at night, reflecting the distribution of food. URI: http://hdl.handle.net/10566/374 Files in this item: 1

Abstract: INTRODUCTION: Literature suggests that a diverse body of healthcare graduates could extend health service delivery. However, the literature also indicates that the throughput of minority, working class, and historically disadvantaged students is problematic. Poor throughput is attributed to the way that university environments alienate some students. This brief communication highlights lessons learned from exploratory interviews with four first-year oral hygiene students at a university in South Africa. It provides insight into the issues that contribute to academic success and failure. METHODS: Semi-structured, individual interviews, to gain information regarding students’ university academic experiences were conducted. Enablers and barriers to learning identified in the literature were used to capture themes. FINDINGS: The following three themes emerged: educational identity, language and finances. The analysis showed how a white middle class student recognized practices that are rewarded at university and how three, working-class, black students experienced tension between their expectations and experiences and the university culture. However, far from being victims, these students provided suggestions on how their transition might be facilitated. CONCLUSION: Evidence suggests that these students wanted both to be apprenticed into the new way of doing things while having their differences acknowledged. A model for education that initiates learners and also challenges the culture of power is suggested. URI: http://hdl.handle.net/10566/60 Files in this item: 1
