  • Description: The aim of this research is to investigate intellectual development of a group of Black mineworkers on a South African gold mine, in the light of their exposure to a technical industrial environment. The research was conducted within a Piagetian framework and attempts to establish:- 1. A conceptual profile which would highlight the subject's conceptual abilities in relation to job skill requirements. 2. An empirical analysis of combined Behavioural and 3. Explanatory responses to support the hypothesis that experienced Black mineworkers should perform better on the diagnostic battery than novices: the main reason for this being the contention that conceptual development is facilitated by cognitive adaptation to the demands of a selectively different technological environment. Whether the battery of Piagetian conservation tasks could be evaluated for use as conservation scales with sound statistical properties. A random sample of fifty six Black mine workers was realised and their performance indicated that:- a ) The concept of Force is not actively developed by mining. b) There was no significant difference in the performance of Novice and Experienced subjects. c) The diagnostic battery in its present form is inadequate and would have to undergo some relative modifications. d) Conceptual profiles showed that concept areas tapped were not developed past the stage of Concrete operations, and that in some instances subjects did not conserve concepts which are relevant to the occupation they were selected for on the Classification Test Battery. e) Piagetian methodology could only be selectively applied to the mining industry for purposes of selection and placement. f) Conservation scales were not realised because of anomalies found in the composition of sub-concepts in the battery. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

  • Description: The nominal species Petrotilapia tridentiger Trewavas, a rock-frequenting fish from Lake Malawi, occurs in three distinct male and female colour forms at Monkey Bay. Field observations on courtship and aggression indicate that the three colour forms are distinct species. The taxonomy of the three species of Petrotilapia that occur at Monkey Bay is revised. R. tridentiger is redescribed and two new species, P. genalutea and P. nigra, are described. The three species are very similar morphologically and are considered to be sibling species. The only morphological character which reliably separates the three sibling species is live coloration: Live coloration is considered to be an important component of the specific mate recognition systems in Petrotilapia species. The coloration of a further fourteen forms of Petrotilapia is described and it is suggested that these forms are valid species. Space resource partitioning plays an important role in facilitating the coexistence of Petrotilapia sibling species. Space is partially partitioned in terms of depth range. In shallow water, where all three species are sympatric, there are differences in the feeding sites used by the various Petrotilapia forms. Changes in niche breadth and overlap, which are associated with changes in the abundance of epilithic algae, indicate that competition for feeding space occurs between the three Petrotilapia species. The Petrotilapia species partition their resources according to a social dominance hierarchy. Dominant forms, such as territorial males, R. tridentiger females and schooling R. genalutea females, have access to rich food supplies which occur within the territories of certain highly aggressive Pseudotronheus species. are facultative and opportunistic .feeders. Petrotilapia species Speciation in allopatry is considered to be the mechanism which adequately explains the current diversity of the genus Petrotilapia. The importance of an integrative approach to future systematic and ecological research on Lake Malawi cichlids is stressed. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 25 , Two new species of percophid fishes are described from off Natal, South Africa, Pteropsaron heemstrai from two specimens dredged at 143 m and Osopsaron natalensis from three specimens dredged at 100 m. This is the first record of a member of the subfamily Hemerocoetinae from the western Indian Ocean. The two new species belong to the lineage of closely related genera Acanthaphrites Gunther, Pteropsaron Jordan and Snyder, Osopsaron Jordan and Starks, Spinapsaron Okamura and Kishida, and Branchiopsaron McKay. A specimen of Squamicreedia obtusa Rendahl, previously known only from the damaged holotype, is described from Western Australia. It is postulated that the genera Squamicreedia Rendahl, Enigmapercis Whitley (whose range is extended to Western Australia), and Matsubaraea Taki form a closely related group in Hemerocoetinae.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 23 , The evolution of the cichlid species flock in Lake Malawi has taken place very rapidly and resulted in the proliferation of a large number of species many of which are similar to one another. This has given rise to a situation in which traditional methods of distinguishing species based on preserved specimens are often of limited value. There are many instances of different species having almost identical morphologies, of single populations of one species showing considerable morphological variation and of marked geographical intraspecific variation. Polymorphism is considered not to be as widespread as previously thought, and pronounced random intraspecific colour variation within a population is discounted. Sympatric sibling species may be distinguished by observing behavioural and habitat differences in the field, but no means has been devised for ascertaining whether morphologically and behaviourally similar allopatric forms are specifically distinct. Lack of access to fresh specimens and lack of information on distribution and habitat have resulted in numerous errors appearing in taxonomic works on Lake Malawi cichlids. Great care is needed when attempting scientific descriptions of cichlid species from the African Great Lakes, and it is suggested that such work be left to specialists with knowledge of living and fresh fish in these lakes.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 24 , Electrofishing surveys throughout Malawi have increased the number of mormyrid species known to occur in the country, expanded known ranges of the species and cast doubts on some earlier records. The distribution of each of the eight recorded species is given, and a key is provided for the identification of the species. The available evidence suggests that Gnathonemus nyasensis Worthington, 1933 is a junior synonym of Marcusenius livingstonii (Boulenger, 1898) a species described from the Ruvuma River of Tanzania. Geological evidence supports fish distribution evidence that indicates links between Lake Malawi and East Coast Rivers. Some affinities are also noted between Lake Malawi and Upper Zambezi/Zaire faunas.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 22 , Plotosus nkunga sp. n., from the east coast of South Africa, possibly ranging as far north as Zanzibar, is most similar to Plotosus limbatus Valenciennes, from the coasts of India, Sri Lanka, Kenya and Aldabra. Plotosus nkunga differs most notably in having fewer total gill rakers on the anterior faces of the first two arches, 16 to 21 versus 20 to 25 first arch, 16 to 24 versus 23 to 27 second arch; in having modally one more precaudal vertebra and slight modal differences in number of ribs and branchiostegal rays; in the shapes of the mesethmoid and the parapophyses of the fourth and fifth centra of the anterior complex vertebra; in the length of the maxilla; and in certain body proportions. Descriptions, annotated synonymies and illustrations are given for both species. A key to the five known species of Plotosus is presented.

  • Description: Voorwoord: In die loop van hierdie studie word dit op enkele plekke duidelik gestel dat die littérature engagée nie beperk is tot die engere "politiek" nie, en dat 'n teks met 'n religieuse tema of 'n teks waarin maatskaplike wantoestande aan die lig gebring word, ook engagé kan wees. Die politiek laat hom egter as magsfaktor oor so 'n wye gebied geld dat nuanserings nie altyd moontlik is nie; 'n teks met 'n oorwegend "religieuse tema" kan politieke implikasies hê. Dit bring verder mee dat selfs 'n teks of 'n bundel waarin géén politieke verwysing voorkom nie, na 'n polities-gemotiveerde keuse teruggevoer word. Die kern van die saak is dat 'n teks tot hierdie subgenre gereken kan word slegs wanneer dit minder of meer uitdruklik kontesteer, of die klimaat skep vir kontestering, wat meebring dat 'n imperatief tot verandering in die teks aanwesig moet wees. Hierdie appél tot verandering rig hom in die beduidendste werke van die genre verbý die partypolitiek, rig hom tot die mens wat (met of sonder sy keuse) onderhewig is aan politieke gebeure. Kontestering (verset) impl iseer ook meebelewing, solidariteit en vereenselwiging. Dit is die oogmerk van hierdie studie om na te gaan hoe aspekte van hierdie vereenselwiging die engagement en die universele waarheid as temamoment en selfs as struktuurfaktor in homself kan verenig. Vanweë die omvang van die teoretiese inset van die studie word tekste in hoofsaak eksemplaries gebruik - déégliker struktulrele analises waarin die estetiese steeds sáám met die die maatskaplik-etiese dimensie ondersoek word, verg 'n afsonderlike studie.

A commentary on Nepos' Life of Alcibiades

  • Description: From Introduction: Much of the commentary is historical and biographical in its emphasis. In making detailed reference to other accounts , I have tried to fill important gaps in Nepos' brief and (in places) abrupt account, to compare the picture of Alcibiades in his account with that of other accounts and to trace sources which he may have used important passages have been quoted in full so that verbal similarities can be seen. A striking feature of Nepos' work is his tendency to describe many non-Roman situations in Roman terms. This reflects not only his vagueness about details (a common fault in his writing), but also perhaps a desire to make his Lives more relevant to his reading public and thus more readable. From antiquity to the present day biography and history have tended to be distinguished from each other, and biography has had the greater popular appeal. Readability is perhaps the most abiding quality of Nepos' Lives and Alcibiades may be the most readable of them all. On the whole Nepos portrays him consistently, although of course he also emphasises the inconsistency which was such an important part of his nature. He has told the story simply, yet dramatically; many of the complicated details about Alcibiades are omitted, yet particular incidents are highlighted, notably the return to Athens and the assassination. Above all, from Nepos' Life there emerges the impression that Alcibiades was unique and worth writing about.

  • Description: From Introduction: This thesis involves a detailed explication of my experience as a client in psychotherapy. Being in therapy has brought about extremely important ·changes in my life and continues to do so. Being involved · in the field of· psychology as a student and therapist-to-be, the experience of therapy has also been a valuable source of a greater understanding of the process itself. The various facets of the importance of my experience of psychotherapy will become clear in my explication. It is a fact that experience, which is an essential aspect of our humanness, has been sadly neglected in psychological research. It is surely psychology's task to explore all aspects of humanity, and this neglect of experience has only fairly recently been questioned. Its reasons have been psychology's bias towards the natural sciences whose methods are not suitable for the study of experience. The tremendous achievements of the natural sciences caused psychology to adopt this slant, as Sigmund Koch (19.69) puts it, "The stipulation that psychology be adequate · to science outweighed the commitment that it be adequate to man".

  • Description: Fifteen species of the labrid fish genus Halichoeres occur in the western Indian Ocean (west of the southern tip of India): hortulanus (centiquadrus of many authors), scapularis, (ziczac is a synonym), marginatus (lamarii, ianthinus and virescens are synonyms), dussumieri (nigrescens of many authors; javanicus, dubius and dianthus are synonyms), pardaleocephalus (first western Indian Ocean record), hoevenii (vrolikii is a synonym), nebulosus (previously confused with margaritaceus which does not occur in the Indian Ocean), zeylonicus (bimaculatus of most authors is a synonym), lapillus, and six new species (stigmaticus, pelicieri, cosmetus, iridis, trispilus, and leucoxanthus). H. stigmaticus from the Persian Gulf is distinctive in having 28 lateral-line scales, 6 or 7 suborbital pores, and a U-shaped black mark on side above pectoral fin tips in males; H. pelicieri from Mauritius is a close relative of H. zeylonicus, differing chiefly in the colour of males (pelicieri with a broad blackish zone in dorsal fin and no large black spot on upper side); H. cosmetus, wide-ranging in the western Indian Ocean and a close relative of H. ornatissimus of the Pacific and Cocos-Keeling Islands, is alternately striped with bluish gray to green and salmon pink or yellow; H. iridis, also a species of the western Indian Ocean, has a dark brown body except for a red band along the back and an orange-yellow head with green bands; H. trispilus, known only from Mauritius and the Maldives, is pale pink with a diagonal row of three dark brown spots on upper caudal base and usually three black dots on back; H. leucoxanthus, known only from the Maldives, southwest Thailand and Java, is yellow dorsally and abruptly white on ventral half of body with a dark spot behind the eye, a black spot on upper caudal base, and three others in the dorsal fin. , Rhodes University Libraries (Digitisation)
