Ultramafic dyke rocks with kimberlitic megacrysts and mantle nodules have been known for decades from the northern part of the Archaean block and adjacent Proterozoic terranes in southern West Greenland (Fig. 1; Escher & Watterson 1973; Goff 1973; Scott 1981; Larsen & Rex 1992; Mitchell et al. 1999). Some of the dykes have proved to be diamondiferous (see Jensen et al. 2004a, b, for exploration results, diamond contents, and references). The c. 600 Ma old dykes werecalled ‘kimberlitic’ by Larsen & Rex (1992), but Mitchell et al. (1999) concluded that they were best referred to a ‘carbonatiteultramafic lamprophyre’ suite (aillikites or melnoites). Mitchell et al. (1999) further suggested that the West Greenland province represents “one of the few bona fide examples of ultramafic lamprophyre which contain diamonds”. Reports on indicator mineral assemblages (Jensen et al. 2004b) and diamond contents (e.g. Hudson Resources Inc. 2005) have re-opened the discussion on the classification of the dykes. The results of an investigation of the Majuagaa dyke (Nielsen & Jensen 2005) are summarised below, together with the preliminary results of a regional investigation of the groundmass minerals of the dykes. It is concluded that dykes in the Maniitsoq region are similar to archetypal, South African, on-craton, Type 1 kimberlites, and that all regions of the West Greenland province of ultramafic magmatism are favourable for diamond exploration.

This paper offers a new way of conceptualising how intersectional solidarities are actualised. It recounts and theorises an outbreak of radical internationalism, when working class struggles in Britain and South Africa were unexpectedly linked. It examines how intersectional solidarity was materialised through a process of coming together against the architectural fabric of the South African Embassy and considers the interwoven temporalities that enabled this action to occur. On 31 March 1990, nearly a quarter of a million people demonstrated in London against the Poll Tax that was due to take effect in England and Wales the following day. On the day, the Metropolitan Police lost control of an already enraged crowd and provoked a large scale riot that engulfed the West End of London for several hours. In the midst of the riot, during a short retreat by the police, protesters took the opportunity to attack the South African Embassy in Trafalgar Square – many windows were broken and an attempt was made to set the building alight. Drawing on interviews with former anti-apartheid protesters who were present on that day (and who had concluded a four-year long Non-Stop Picket of the embassy a month earlier), this paper explores and analyses their memories of that unexpected moment when their previously symbolic call to ‘burn it down’ was (almost) materialised. In doing so, it contributes new ways of conceptualising the spatiality and temporality of intersectional solidarity.

The South African fossils with broad, flat, tuberculate tooth-crowns of mammalian type all from the eastern part of Cape Colony. Some of the most interesting are known from fragments, which indicate nothing but the middle region of the sail. They are apparently extremely rare. Two species, with teeth well preserved, found ten years ago by Dr. Kannemeyer, at Wonderboom, and presented to South African Museum, Cape Town, where they were brought under my notice by Peringuey. Others were found in a fragmentary condition by Mr. Alfred of Aliwal North, to the west of that town, in a bed which appeared to me be reconstructed. There is no doubt that the fossils are from the upper part of te Karroo formation, probably of Permian age, and below the Stormberg beds, in Saurischian fossils are found allied to those of the Trias of Europe. If the teeth had occurred isolated, without the means of demonstrating their rsemblance to Theriodonts, by comparison of what remains of the skull, it would have legitimate to have referred them to Mammals. There is no evidence of affinity Accept resemblances to Theriodonts, which show that the skull had pre-frontal and frontal bones, and therefore may be inferred to have had the lower jaw composite. The teeth are such as might be expected, perhaps, in a Monotreme Mammal, their interest is therefore the greater that there is no ground for suspecting them be mammalian, other than a general resemblance of the crown to the crowns of true teeth of Ornithorhynchus. That teeth of this type should occur in a group animals in which the shoulder-girdle and pelvis have monotreme characters, and in hich the principal limb bones are intermediate in character between Monotremes Marsupials, is evidence of a closer approximation between Mammals and Pep tiles has been manifest. And so far as I am aware the only Theriodont characters remaining to distinguish these animals from Mammals are the composite lower which is covered externally by the dentary bone along its whole length, and the resence of the pre-frontal, post-frontal, and transverse bones in the skull.

Differences in parasite infection have previously been used to distinguish between fish stocks. We demonstrate a novel use of parasite prevalence-by-length data to inform quantitatively on stock mixing. An initial two mixing stock hypothesis proved consistent with biological and survey data, suggesting that there are different stocks of sardine off the west and south coasts of South Africa. That hypothesis assumed that only recruits moved from the west to the south stock. However, new “tetracotyle”-type metacercarian parasite bio-tag data indicate a need to allow older fish to move between the stocks as well. We demonstrate extension of bio-tagging to inform on the plausibility of population structure hypotheses by including parasite prevalence-by-length data in the model’s likelihood. Our method enables the estimation of the magnitude of mixing between semidiscrete stocks, providing more precise estimates of annual movement. Such improved precision may be important in better informing future movement hypotheses and thereby management. Our research provides a framework to use to inform quantitatively on stock structure and movement hypotheses for other fish species with bio-tagging data.

Orientation: Various countries recognise human resource (HR) management as a bona fide profession. Research purpose: The objective of this study was to establish whether one could regard HR management, as practised in South Africa, as a profession.Motivation for the study: Many countries are reviewing the professionalisation of HR management. Therefore, it is necessary to establish the professional standing of HR management in South Africa.Research design, approach and method: The researchers used a purposive sampling strategy involving 95 participants. The researchers achieved triangulation by analysing original documents of the regulating bodies of the medical, legal, engineering and accounting professions internationally and locally as well as the regulating bodies of HR management in the United Kingdom (UK), the United States of America (USA) and Canada. Seventy- eight HR professionals registered with the South African Board for People Practices (SABPP) completed a questionnaire. The researchers analysed the data using content analysis and Lawshe’s Content Validity Ratio (CVR).Main findings: The results confirm that HR management in South Africa adheres to the four main pillars of professionalism and is a bona fide profession.Practical/managerial implications: The article highlights the need to regulate and formalise HR management in South Africa.Contribution/value-add: This study identifies a number of aspects that determine professionalism and isolates the most important elements that one needs to consider when regulating the HR profession.

In discussing the African Trypetidae some mention should be made of the work of the late Dr. Mario Bezzi, who has perhaps done most work on the higher Diptera of Africa and on the Trypetidae in particular. In 1924 in his papers in Vol. xv of the “ Bulletin of Entomological Research ” and in Vol. xix of the “ Annals of the South African Museum,” Bezzi left the classification of the African Trypetidae in as satisfactory a condition as any systematic group could be expected to be at any given time. Some discrepancy was apparent, however, between the classification of the African and of the European Trypetidae, the general classification of the latter apparently not having been touched since Loew's early work. The appearance, therefore, of Dr. F. Hendel's monograph on the Palaearctic Trypetidae in Lindner's “ Die Fliegen der Palaearktischen Region ” was greatly to be welcomed. At the same time, his classification does not agree with that of Bezzi ; Hendel has made numerous nomenclatorial and systematic changes, and the correlation of the two systems will not always be easy.

Self-regulation of the professions of nursing and midwifery became a reality in South Africa on 8 November 1944, when the first council meeting of the South African Nursing Council took place in Pretoria. Most appropriately, the opening speaker on this occasion was Mr Harry Gordon Lawrence, the Minister of Welfare and Demobilization, who had piloted the Nursing Act, No.45 of 1944, through Parliament. Exactly 50 years later, on 8 November 1994 the Council held its 108th meeting, this time in its own building, with a magnificent view of the venue where that historic first meeting took place - the west wing of the Union buildings.

The prevalence and diversity of bartonellae infecting the blood of 10 small mammal species inhabiting nine Nature Reserves of the Free State province, South Africa, was assessed using phenotypic, genotypic and phylogenetic methods. Of 86 small mammals sampled, 38 animals belonging to five different species yielded putative bartonellae. Thirty-two isolates were confirmed as bartonellae and were characterized by comparison of partial citrate synthase gene (gltA) sequences. Phylogenetic reconstructions derived from alignment of these sequences with those available for other bartonellae indicated that the South African rodent-associated isolates formed two distinct clades within the radius of the genus Bartonella. One of these clades also included recognized Bartonella species associated with rodents native to Eurasia but not to the New World, whereas the second clade contained exclusively isolates associated with South African rodents. Comparison of gltA sequences delineated the isolates into a number of ecologically distinct populations and provided an indication that a combination of phylogenetics and the identification of sequence clusters in housekeeping protein-encoding genes could be developed as a key criterion in the classification of bartonellae. This study is the first to investigate wildlife-associated bartonellae in Africa, adding support to their ubiquity and broad diversity and to the paradigm that the phylogenetic positions of the Bartonella species encountered today have been influenced by the geographical distribution of their hosts.

The article addresses the classification of Kyiv murals of the early 21st century, made by foreign artists (USA, Canada, France, United Kingdom, Belgium, Australia, Spain, Portugal, Argentina, Brazil, Costa Rica, South Africa, etc.). The image of Ukraine in the work of these artists, who got to know Ukraine forcedly, episodically, and inevitably scarcely, isthe image of the Other on the territory of this Other. As a result, “others” (foreign artists) overcome their own otherness and enter into cultural dialogue with other culture and the city, the notable part of which their murals become. Along with animalistic motifs (mainly ornithological), this area is dominated by the archetypal images of Ukrainian history and culture, bizarrely supplemented by their own reminiscences and additions (mural Berehynia). However, signs of simulacrum is not the case. It is rather a carnival fantasy that traces the influence of Baroque culture, which has deep roots in Ukraine. There are precedents of collaboration with Ukrainian authors (mural Vidrodzhennia (Renaissance) by Julien Malland and Oleksii Kyslov). Occasionally, foreign artists use only certain attributes of local life (embroidery pattern), directly reflect on the impressions of the present, transplanting them into the European context (mural Night Kyiv). Also from time to time they turn to real characters of national history and culture (Serhii Nigoian, Lesia Ukrainka, in the latter case Guido van Helten boldly reformed the established image iconography of the “daughter of Prometheus”, giving his heroine the features of a modern feminist), as well as sports (gymnast Hanna Rizatdinova). It was concluded that there is a long-term cultural dialogue between the West and Ukraine, with the first party presenting maximum interest and tolerance.

Sorghum Bicolor L

In recent years considerable research has been carried out on cultivated Sorghum bicolor (L.) Moench in an attempt to acquire a more complete and meaningful understanding of the taxonomy, classification, origin and evolution of Africa's most valuable cultivated crop. This work has, however, been restricted mainly to the sorghums in northern and central Africa, with southern Africa largely excluded. In this paper, the morphological variation and distribution of cultivated sorghum races in South Africa is introduced, together with comments on the classification of cultivated sorghums. A new morphological character, the groove at the base of the lower glume of mature, sessile spikelets (developed from a zone of weak, membranous tissue observable in immature spikelets) is evaluated. The degree of development of this groove varies between the different races and is considered to relate directly to their evolution and domestication.
