Abstract. An electrophoretic survey of allozyme variation revealed substantial genetic differentiation within the eastern Australian population of Actinia tenebrosa. This differentiation appears to reflect the effects of both asexual reproduction and limited gene flow among local populations separated by up to 1050 km. Variation was assessed within groups of 27 to 55 adults sampled between September 1985 and December 1988 collected from small areas of shore within each of 24 local populations. All individuals were collected from stable rock platforms, with the exception of Boulder Bay, where some sea anemones were removed from small mobile boulders. High levels of variability were detected for each of seven enzyme-encoding loci. The patterns of genotypic variation detected imply that local populations are maintained by predominantly asexually generated recruitment. Levels of multi-locus genotypic diversity within samples were consistently less than 50 % of the level expected for sexual reproduction with free recombination. This was reflected by the detection of relatively low numbers of multi-locus genotypes and significant departures from expectations for single-locus Hardy-Weinberg equilibria within 17 of the 24 local populations. Standardised genetic variances (Fsr), calculated from the genotypes of all individual adults were typically much greater than those expected for marine organisms with widely dispersed larvae. The former values were reduced, but were still extremely large when "clonal" genotype frequencies were substituted into the calculation.
Vocabulary is an essential component of study, of reading and writing skills. At present, English is the primary language of tertiary education in South Africa, and this puts students from other language backgrounds at a disadvantage. The proposed dictionary will therefore be aimed at second language English users who are entry level students at university. It will be in four languages: English, Afrikaans, Zulu and Sepedi. I.S.P. Nation and J. Coady have compiled an academic core vocabulary which tertiary students in all subject fields need to master in order to be able to encode and decode tertiary level texts, and this has been the basis for the planned dictionary. However, this list needs to be compared to and updated with material from a South African academic corpus. A preliminary comparative study has been conducted on the basis of authentic South African data, and a revised list has been created. The dictionary will not be subject-specific, but will deal with a general sub technical vocabulary. Full definitions will be provided in all four languages, as well as translation equivalents, with English as the pivot language. Where a lexical gap occurs, translation equivalents will be coined with the help of the relevant experts. Thus the dictionary will also participate in much-needed corpus development of the African languages. It should become a valuable reference tool for both teacher and student. Tans is Engels die primere taal van die tersiere onderwys in Suid-Afrika, en dit benadeel studente met ander taalagtergronde. Die beplande woordeboek is derhalwe gerig op eerstejaaruniversiteitstudente wat Engels as tweede taal gebruik. Dit sal in vier tale wees: Engels, Afrikaans, Zulu en Sepedi. I.S.P. Nation en J. Coady het 'n akademiese kernwoordeskat saamgestel wat tersiere studente in aile studierigtings behoort te ken om tekste op tersiere vlak te enkodeer en te dekodeer, en dit het as basis vir die beplande woordeboek gedien. Hierdie Iys moet egter vergelyk en opgedateer word met materiaal uit 'n Suid-Afrikaanse akademiese korpus.

In this article, I reflect on my ever-evolving epistemological journey through which I came to embrace a “wholistic” qualitative methodology for my doctoral research in social work. I offer a chronological account of my lived experiences starting with my locus of origin and highlighting the challenging twists and turns that brought me to my research interest of exploring meaningful peer support relationships in mental health and addictions agencies.
