In recognition of our universal human condition : a response to Caduri's universality plus difference
No full textCITATION: Davids, N. 2013. In recognition of our universal human condition : a response to Caduri's universality plus difference. South African Journal of Higher Education, 27(3).In her commentary on my article, 'A reformed Islamic education: Grounds for revisiting cosmopolitanism' (Davids 2012), Caduri (2013) highlights three difficulties. The first one she describes as a conceptual ambiguity with regard to my use of the term 'identity', which leads to me contradicting myself. Her second difficulty relates to my argument for attaching more value to the other - which she interprets as an attempt to avoid a relationship of power, and then diagnoses as suffering from self-refutation. And her third difficulty lies with my claim to articulate a new cosmopolitanism which does not separate individuals from their culture, which Caduri dismisses as a resonance rather than an innovative theory. In responding to Caduri's afore-mentioned difficulties, I will commence with what I consider to be her most problematic commentary - her concluding verdict that, 'Davids swims against the current by challenging her roots as well as the widespread fundamentalist view of Islam in a very convincing way, allowing her personal voice to emerge. Thus, reading her article might change not just what people know, but also who they are.'Publisher's versio

Holotype: SAMC-A029002 (in ethanol), station TRA 31 (34°49’S, 20°21.5’E), off Arniston, South Coast, South Africa, UCT Ecological Survey, trawl, depth 86 m, 9 September 1947. Additional material: SAMC-A 077262 (in ethanol), FAL 330. Additional comparative material: Cribrilina simplex, NHMUK 1963.3.20.2 (part of type), No. 27G, Still Bay, South Coast, South Africa, UCT Ecological Survey, 5 January 1932, no additional information. Cribrilaria africana, NHMUK 1983.11.5.75 (paratype), station SM 164 (33°04.6’S, 28°06.6’E), off East London, Southeast Coast, South Africa, RV Meiring Naude Survey, heavy dredge, depth 90 m, 26 May 1978. Cribrilaria innominata, SAMC-A 026567, station SM 163 (33°04.6’S, 28°06.6’E), off East London, Southeast Coast, South Africa, heavy dredge, depth 90 m, 26 May 1978. Etymology. Named after the first author’s grandmother, ‘Ouma’ Caroline Keet (née Abrahams) (b. 1933). She deeply invested in her children’s education during the difficult circumstances of the ‘Apartheid’ Era; the strong role she plays in her family is hereby acknowledged. Diagnosis. See genus. Description. Colony encrusting; colour creamy white and translucent in ethanol preserved material. Zooids closely juxtaposed with vertical walls directly abutting each other. Autozooid elliptical to subrectangular, about 0.66 mm long by 0.42 mm wide; frontal shield composed of seven to ten pairs of costae, flat to slightly convex, gymnocystal margin extremely reduced; three to four rounded intercostal lacunae aligned in rows on each side, fused completely along the mid-line where tips of the costae meet, sometimes forming an additional small lacuna. Orifice wider than long, deep semicircular, smooth edged; a thick, overarching apertural bar obscuring the primary orifice; secondary orifice with a U-shaped pseudo-sinus (V-shaped in giant dimorphic zooids) formed by a pair of projections close to the midline of the costae forming the apertural bar. Dimorphic zooids interpreted as brooding zooids, same shape and structure as ordinary autozooids but larger, about 1.27 mm long by 0.69 mm wide (N T = 1), scattered throughout the colony; three to nine rounded intercostal lacunae on each side. Interzooidal avicularia spatulate, about 0.52 mm long by 0.18 mm wide (N T = 2), scattered throughout the colony; rostrum raised and cup-like. Interzooidal communication through uniporous mural septula. No apparent ovicells or ooecia, brooding presumably taking place in dimorphic zooids. Ancestrula not observed. Remarks. Three known species of Cribrilinidae were previously described from South Africa: Cribrilina simplex O’Donoghue & de Watteville, 1935, C. dispersa O’Donoghue & de Watteville, 1937, and Cribrilaria africana Hayward & Cook, 1983. The widespread C. innominata (Couch, 1844) has also been reported from this region (Hayward & Cook 1983). Khulisa carolinae n. gen. et n. sp. differs in several features from all the above-mentioned species (see also Remarks for the genus). Khulisa carolinae n. gen et n. sp. forms encrusting patches on hard substrata including bryozoans, for example Reteporella sp. It was sampled near Arniston and False Bay, east of Smitswinkel Bay, on the South Coast, at 51–86 m depth.Published as part of Boonzaaier-Davids, Melissa K., Florence, Wayne K. & Gibbons, Mark J., 2020, Novel taxa of Cheilostomata Bryozoa discovered in the historical backlogs of the Iziko South African Museum, pp. 105-133 in Zootaxa 4820 (1) on pages 116-118, DOI: 10.11646/zootaxa.4820.1.5, http://zenodo.org/record/439737
Reflecting on a doctoral supervision : from scepticism to friendship
No full textPlease cite as follows:Waghid, Y. & Davids, N. 2013. Reflecting on a doctoral supervision: From scepticism to friendship: Initiating the debate. South African Journal of Higher Education, 27(4):769-780.The original publication is available at http://reference.sabinet.co.za/sa_epublication_article/high_v27_n4_a1 SEE ALSO - http://hdl.handle.net/10520/EJC150428In this article two colleagues are in conversation regarding doctoral supervision: The first author acted as a doctoral supervisor, while the collaborative author was a doctoral candidate during three years of study. The first author offers a narrative account of his sceptical encounter with the candidate while the candidate offers an account of her experiences during her doctoral studies. Drawing on the seminal thoughts of Harvard philosopher Stanley Cavell (1997), particularly on his ideas on 'living with scepticism', the first author argues that postgraduate student supervision ought to be an encounter framed by scepticism. He points out that supervising students sceptically might engender moments of acknowledging humanity within the Other (autonomous action); attachment to the Other's points of view with a readiness for departure (deliberative engagement); and showing responsibility to the Other (recognition of the other). Not necessarily in response, but certainly in conversation, the candidate presents her own experiences of encountering two unknowns, namely, the writing process demanded by a doctoral dissertation, and the unknown Other of a doctoral supervisor. She journeys her shift from naïve attachment to a writing that she thought she owned to one of mature detachment, strong enough to stand on its own. In exploring the necessary sense of completion and arrival that ought to accompany the doctoral process, the candidate singles out elements of trust, belief and the knowledge that the doctoral supervisor ought to attach the same value to a student's work as he/she does. Finally, in recognition of the unexpected of the doctoral journey, the candidate reflects on the flourishing of a friendship, which emerged from an encounter of scepticism
Hippomonavella lingulata Boonzaaier-Davids & Florence & Gibbons 2020, n. sp.
No full textHippomonavella lingulata n. sp. (Fig. 8 A–E, Table 7) zoobank.org/ 895C8035-EB64-418E-90E5-71BD671C358B Material examined. Holotype: SAMC-A029050 (in ethanol), station AFR273 A31624 (33°48’24”S, 25°56’48”E), Algoa Bay, Southeast Coast, South Africa, South Coast Demersal Survey, trawl, depth 45 m, 21 April 2011. Paratype: SAMC-A028993 (in ethanol), AFR273 A31624, see station data above. Additional comparative material: Hippomonavella formosa, SAMC-A028621, Bakoven (33°56’S, 18°22’E), West of Cape Peninsula, South Africa, collected by W. Florence, depth 8 m, 5 May 1999; SAMC-A028622, Saldanha Bay (33°01’S, 17°59’E), West Coast, South Africa, collected by W. Florence, depth 10 m, 25 February 2001. Etymology. From the Latin, referring to the tongue-shaped avicularium. Diagnosis. Colony encrusting. Autozooids with imperforate frontal shield except conspicuous marginal areolae. Orifice with proximally slanted condyles and flaps developing laterally. Distal oral spine present, not visible in ovicelled zooids. Avicularia adventitious, sub-lingulate. Ovicell hyperstomial; ooecium formed by the distal autozooid, smooth and pseudoporous. Description. Colony encrusting. Autozooids oval, rectangular to irregularly polygonal, about 0.78 mm long by 0.50 mm wide, separated by raised sutures. Frontal shield imperforate, nearly smooth or unevenly textured, with a single series of about 17–23 (N T = 8) conspicuous marginal areolae. Orifice circular to roundly subquadrate, with slight median concave proximal rim and a pair of proximally slanted condyles. A pair of distal oral spine bases usually present, except in ovicelled autozooids; a pair of flaps developing lateral to the orifice. Avicularium median, proximal to orifice, sub-lingulate, small opesia, long palatal shelf, rounded rostrum proximally raised, almost one third of the total length of autozooid, directed proximally, with complete crossbar or, less frequently, condyles. Ovicell hyperstomial; ooecium formed by the distal autozooid, longer than wide, flattened frontally, smooth with about 38 (N T = 1) rounded or irregular shaped frontal pseudopores; secondary calcification of distal zooid(s) covering distal part of ovicell. Mural pore chambers in lateral walls. Ancestrula not observed. Remarks. This species is confidently placed in Hippomonavella based on the presence of conspicuous marginal areolae, hippoporine orifice and adventitious suboral avicularia. Globally, about 19 Hippomonavella species are known, of which more than half are extinct (www. bryozoa.net, accessed 06 June 2020). In South Africa, H. formosa MacGillivray, 1887 has been reported from the West Coast (Florence et al. 2007). Hippomonavella lingulata n. sp. differs from H. formosa in having a straight proximal orificial rim and a median suboral avicularium. In fact, the other known extant Hippomonavella species, including H. pellucidula Hayward & Ryland, 1991, H. gymnae Gordon, 1984, H. ramosae López de la Cuadra & Garcia-Gomez, 2000 and H. brasiliensis Ramalho, Muricy & Taylor, 2008, differ from H. lingulata n. sp. in the position and size of avicularia, orifice shape and smaller marginal pores. The new species closely resembles H. flexuosa Hutton, 1873 from New Zealand in having sub-lingulate median avicularium, in the number of conspicuous marginal areolae, and the paired oral spines (Gordon 1989), but it lacks the proximal median convexity of the orifice and the sizeable avicularium. Particularly, the median avicularium covers almost one third of the total autozooid length in H. lingulata n. sp. as opposed to almost one sixth of the total autozooid length in H. flexuosa. No ancestrula was observed in H. lingulata n. sp. and therefore has not been described. The ancestrula and early astogeny of a species of Hippomonavella were only recently described for the first time (López-Gappa et al. 2020). Hippomonavella charrua López-Gappa, Liuzzi & Pereyra, 2020 has tatiform ancestrula with nine, delicate, cylindrical spines surrounding a circular opesia, and a band of proximal cryptocyst, budding three periancestrular zooids with five spines. Hippomonavella lingulata n. sp. was found at Algoa Bay, on Southeast Coast, at 45 m depth.Published as part of Boonzaaier-Davids, Melissa K., Florence, Wayne K. & Gibbons, Mark J., 2020, Novel taxa of Cheilostomata Bryozoa discovered in the historical backlogs of the Iziko South African Museum, pp. 105-133 in Zootaxa 4820 (1) on page 121, DOI: 10.11646/zootaxa.4820.1.5, http://zenodo.org/record/439737

Holotype: SAMC-A 028985 (dry), station AFR273 A31666 (34°58’51”S, 21°36’52”E), south of Cape Infanta, South Coast, South Africa, Africana South Coast Demersal Survey, trawl, depth 95–97 m, 5 May 2011. Additional comparative material: Trypostega venusta (= T. richardi n. sp.), SAMC-A 026788, station SM 164 (33°04.6’S, 28°06.6’E), off East London, Southeast Coast, South Africa, RV Meiring Naude Survey, heavy dredge, depth 90 m, 26 May 1978. Trypostega venusta, SAMC-A 026809, station SM 163 (33°04.6’S, 28°06.6’E), off East London, Southeast Coast, South Africa, heavy dredge, depth 90 m, 26 May 1978. Etymology. Named after the first author’s father, Richard Lawrence Boonzaaier (b. 1953). As school teachers and former principals under the difficult circumstances and education system of the ‘Apartheid’ Era and post-‘apartheid’, both her parents have shown remarkable levels of commitment and motivation in teaching children in South Africa. His courage and endurance, and patience, love and support throughout her study career and life is hereby acknowledged. Diagnosis. Colony encrusting, unilaminar. Autozooids with hyaline, evenly pseudoporous frontal shield; pseudopores aligned in an arch distally. Orifice dimorphic, cleithridiate with narrow U-shaped sinus, broader and shallower in ovicelled zooids. Suboral umbo absent. Zooeciules placed distal to most autozooids, sometimes in clusters. Ovicell subimmersed; ooecium formed by the distal kenozooid, ectooecium with scattered pseudopores. Description. Colony encrusting, unilaminar, forming thin sheets; colour greyish to creamy white in dried material. Autozooids rounded rhomboidal or irregularly polygonal, elongate, separated by distinct sutures. Frontal shield smooth, slightly convex or flat, hyaline, evenly perforated by 55–100 (N T = 7) circular pseudopores; pseudopores distal to the orifice aligned in an arch. Orifice dimorphic, keyhole-shaped with prominent condyles (cleithridiate), longer than wide; rounded anter, separated from a narrow U-shaped sinus, broader and shallower in ovicelled zooids, by a pair of short, proximally directed condyles; slightly raised rim bordering the orifice. No suboral umbo. Zooeciules, of varying size and shape, placed distally to most autozooids or between two adjacent autozooids, either single, twinned or in clusters of up to seven; evenly pseudoporous similar to autozooid frontal shield; small, elliptical or rounded opening, bordered by a slightly raised rim. Ovicell subimmersed, cleithral; ooecium formed by the distal kenozooid associated with the terminal zooeciule, ectooecium with evenly scattered pseudopores. Ancestrula not observed. Remarks. Only part of the colony (less than 20 autozooids) was detached from the original substrate (scleractinian coral) and examined using SEM. Although all cleithridiate, the orifice of Trypostega richardi n. sp. differ from those of T. dorothysouleae Tilbrook, 2006, T. johnsoulei Tilbrook, 2006, T. venusta Norman, 1864 and T. maculata Tilbrook, Hayward & Gordon, 2001. In the new species the sinus is narrow and U-shaped, while the species above-mentioned all possess a broader and shallower U-shaped or horseshoe-shaped sinus. Additional features that distinguish T. richardi n. sp. from other known species, including the most similar T. henrychaneyi Tilbrook, 2006, are the irregularly shaped zooids and the frequency of zooeciules. The zooeciules are sporadic and mostly placed distally to autozooids, but they may also form clusters of up to seven. Hayward and Cook (1983, p. 86) reported a few colonies of the widespread T. venusta on the Southeast and East Coast of South Africa, which differ from T. richardi n. sp. in having shallow, horseshoe-shaped sinus, and also much less frequent zooeciules. Upon examining some of the voucher specimens of T. venusta in the SAMC collection, one of the colonies (SAMC-A026788) determined as T. venusta is, in fact, T. richardi n. sp. (Fig. 5 A–D). Trypostega richardi n. sp. was sampled off Cape Infanta on the South Coast of South Africa at 95–97 m depth.Published as part of Boonzaaier-Davids, Melissa K., Florence, Wayne K. & Gibbons, Mark J., 2020, Novel taxa of Cheilostomata Bryozoa discovered in the historical backlogs of the Iziko South African Museum, pp. 105-133 in Zootaxa 4820 (1) on pages 114-115, DOI: 10.11646/zootaxa.4820.1.5, http://zenodo.org/record/439737

Additional comparative material: Micropora similis, SAMC-A026418 (holotype), station SM 163 (33°04.6’S, 28°06.6’E), off East London, Southeast Coast, South Africa, RV Meiring Naude Survey, heavy dredge, depth 90 m, 26 May 1978; SAMC-A026525, same station as above. Micropora latiavicula, SAMC-A028594 (holotype), Saldanha Bay (33°01’S, 17°59’E), West Coast, South Africa, collected by W. Florence, depth 15 m, 15 February 2001. Etymology. From the Latin, referring to the erect colony growth form. Diagnosis. Colony erect, bilaminar. Autozooids with cryptocyst smooth centrally and granular along the margins with small pseudopores; opesiules paired, finely toothed. Opesia with raised proximal rim and indentations. Interzooidal avicularia present. Ovicell hyperstomial; ooecium granular, smooth proximally. Description. Colony erect, forming broad, bilaminar branches, raising from an encrusting base; colour light brown to yellow in ethanol preserved material, creamy white in dried material. Autozooids elongate, rectangular, about 0.70 mm long by 0.30 mm wide, sometimes tapered proximally. Cryptocystal surface smooth centrally, granular along the zooidal margins, with 16–33 (N T = 10) circular, oval to irregularly shaped pseudopores of variable size; distolateral walls of autozooid forming a raised nodular rim below the opesia; rarely parts of the frontal shield unevenly raised by secondary calcification. Opesia wider than long, semicircular, with straight proximal border and paired opesiular indentations; paired opesiules finely toothed, placed proximal to the thickened orificial rim. No spines. Interzooidal avicularia present; crossbar complete, rostrum acute, directed obliquely distally. Ovicell hyperstomial, cleithral, with dimorphic opening; ooecium formed by the distal autozooid, with membranous ectooecium and calcified entooecium, partially covered by secondary calcification. In cleaned specimens, ooecium with granular surface, except for a narrow, smooth proximal border. Remarks. Globally, there are 70 known Micropora Gray, 1848 species, of which nearly half are extinct (www. bryozoa.net, accessed 06 June 2020).? Micropora erecta n. sp. closely resembles M. angusta MacGillivray, 1887, in the zooidal shape, the position of interzooidal avicularia and opesiules but it differs in having erect growth form and smooth cryptocyst centrally. Numerous other species (e.g. M. mawatarii Arakawa, 2016, M. plana Arakawa, 2016 and M. rimulata Canu & Bassler, 1929) differ from? M. erecta n. sp. in having evenly granular frontal surfaces. ? Micropora erecta n. sp. was also compared to Micropora species found in the Indian Ocean. Micropora latiavicula Florence, Hayward & Gibbons, 2007 from South Africa is distinguished by its slender zooids, interzooidal avicularia with broad sloping rostra that are directed obliquely distally, deep and circular opesiules proximal to the orifice on either side, and accessory opesiule openings subjacent to the primary opesiules. Another species reported previously from South Africa, M. similis Hayward & Cook, 1983, can be distinguished by the small distinct bosses adjacent to the opesia, slender autozooids and densely punctured cryptocyst (Hayward & Cook 1983).? Micropora erecta n. sp. differs from both, because it lacks accessory opesiules, has a smooth frontal surface (though granular along the zooidal margins) and indentations at the proximal corners of the opesia (Fig. 4C). This new species seemingly differs from typical Micropora species and other known genera in the family Microporidae Gray, 1848, and is only tentatively assigned to Micropora based on the structure of the ovicell (Ostrovsky 2013), semicircular orifice, paired opesiules and presence of interzooidal avicularia. ? Micropora erecta n. sp. was found from the Southwest Coast at Cape Peninsula to Agulhas Bank, including False Bay area, on the South Coast at 38–147 m depth.Published as part of Boonzaaier-Davids, Melissa K., Florence, Wayne K. & Gibbons, Mark J., 2020, Novel taxa of Cheilostomata Bryozoa discovered in the historical backlogs of the Iziko South African Museum, pp. 105-133 in Zootaxa 4820 (1) on pages 112-113, DOI: 10.11646/zootaxa.4820.1.5, http://zenodo.org/record/439737
