- Description: Nationalisation involves putting any section of the economy under the control and ownership of a government. Nationalisation is not new to South Africa. The governments of the past and especially the Nationalist Party have nationalised a number of industries in the South African economy. Today almost 54% of the productive assets in the country are in the hands of the government. Transport, electricity, post office, are a few examples. Nationalisation in the past has been used to benefit only the whites, by providing them with jobs and services.

- Description: A new stem-group chondrichthyan fish, PlesioselacJllIs macracanthlls gen. et sp. nov., is described from the Late Devonian Witpoort Formation, representing an estuarine lagoon site, near Grahamstown, South Africa. Based on a single, fairly complete specimen, it is distinctive in its a single dorsal fin braced by a large, stout spine with numerous ribs and posterior denticles, apparently no second dorsal or anal fin, an amphistylic jaw suspension, and a distinctive triangular palatoquadrate. It is suggested that the species may represent a high-latitude, Late Devonian relict taxon.

He had a profound commitment to creating a just and humane society. Through a long and distinguished association with the higher education sector, as an academic, dean, vice-chancellor, chairperson of the Committee of University Principals in the early 1990s, chancellor, and chairperson of the Mandela Rhodes Foundation, Gerwel was an outstanding champion of higher education. As chancellor, he challenged Rhodes to become socially conscious and think critically and imaginatively about access, equity and transformation, and about its role in socioeconomic development issues in South Africa, especially in the Eastern Cape.

- Description: From introduction: This afternoon we publicly launch an exquisite tapestry commissioned from the Keiskamma Arts Project based in Hamburg on the coast. It is intended to express the social purposes that are the rationale for our existence; the geography and environment of Rhodes University; the economic, political, historical and social forces that have shaped it over 107 years and the complexity, antinomies, paradoxes and ambiguities of Rhodes’ history. It is also intended to express our origins, where we have come from the road we have travelled and where we are today; the continuities and discontinuities that characterise Rhodes; the inexcusable and shameful actions of our past in which we can take no pride, as well as the courageous actions, successes and achievements in which we can take pride, and that we can and must celebrate. The launch of the tapestry is an important moment in our continuing journey as Rhodes University of critical reflection, ‘critical appreciation of where we come from,’ and ‘dialogical and analytic engagement with where we are now’ and where we seek to be in future. I have indicated that the launch of the tapestry is a moment in our continuing journey – a journey of the remaking, renewal, modernisation, transformation and further development of Rhodes University.

This was, however, also a time of great optimism for it was clear that apartheid tyranny could no longer continue and had to give way to a new social order. We must take immense pride in the imagination, creativity, ingenuity and courage that we displayed as a people to rid ourselves of tyranny and to fashion our democracy. You are a generation that has been, thankfully, largely spared the horrors, brutality and injustices of apartheid. You are the first generation with the opportunity of living in a society founded on a democratic Constitution that proclaims the commitment to human dignity, the achievement of equality, and the advancement of non-sexism and non-racialism and the human rights and freedoms that are contained in our Bill of Rights.

- Description: There are social and political questions to be asked about the new continent-wide institutions in and around what is still a young African Union (AU). These include questions such as whether the AU and its institutions can be built in ways that will allow this body to transform Africa's international relations, and how this is to be done. What are the norms and values that will inform this change and the African renewal promoted by the AU? Is the multilateral architecture of the AU able to encourage democracy and people-centredness, for instance? Will it, in the end, be able to deliver on the hoped-for "pan-African transnational democratic revolution"?.

- Description: Research on quality of life and subjective well-being (SWB) has witnessed a remarkable growth over the past four decades or so. Since Easterlin’s (1974) seminal contribution on the relationship between happiness and income, thousands of studies have followed that examine the intricacies of subjective well-being (for reviews, see Frey and Stutzer, 2002; Dolan et al., 2008; MacKerron, 2012). These studies have uncovered some very important aspects of individual well-being and have pointed to the fact that money or income is not always (as is often assumed) the most important determinant of SWB.

This study examines the impact of presenting side effect information using simple text combined with pictograms on sustained knowledge of ARV side effects over three months. Previously designed side effect pictograms, combined with simple text, were incorporated into a side effects panel within an ARV information leaflet. In a randomised controlled study, 116 limited literacy HIV patients taking ARVs were randomly allocated to either control (standard care) or intervention groups (standard care plus illustrated information). Side effect knowledge was assessed at baseline, and intervention patients received the illustrated leaflet. Knowledge was re-tested at one and three months. Interpretation of side effect pictograms was evaluated at one month.

- Description: We report the dosimetric features of ultra-high molecular weight polyethylene (UHMWPE) using luminescence optically stimulated using 470 nm blue light. Samples irradiated to between 1 and 1000 Gy produces luminescence that increases with irradiation dose to produce a linear dose response between 1 and 1000 Gy. The sample was determined not to be affected by pre-dose in tests using a pre-dose of 4000 Gy. This characteristic precludes the need for elaborate background erasing routines typical of dosimetry experiments. The signal has good reproducibility. We used this property to test recovery of ‘unknown’ doses with encouraging results. It was observed that luminescence can also be stimulated using 870 nm infrared light. The dose response, fading, pre-dose effect and the ability to optically stimulate luminescence from the polymer is discussed in terms of curing involving free-radicals.

- Description: The radioluminescence of synthetic quartz annealed at various temperatures up to 1000 °C is reported. The amplitude of the emission bands increases with annealing temperature. In addition, when samples are annealed at temperatures exceeding 700 °C, the intensity of the radioluminescence increases with duration of annealing. The corresponding emission spectra show seven emission bands at 2.04, 2.54, 2.77, 3.04, 3.40, 3.75 and 3.91 eV. The change in dominant emission band with annealing is consistent with annealing-induced variations in lifetimes determined previously from time-resolved optically stimulated luminescence spectra in the same samples.

- Description: Thaumatotibia leucotreta Meyrick (Lepidoptera: Tortricidae) is a key pest of citrus in South Africa. In addition to the fruit damage caused, export markets such as the United States, South Korea and China regulate T. leucotreta as a phytosanitary organism in addition to restricting the use of pesticides on exported fruit (Grout & Moore 2015; SA-DAFF 2015). The bulk of citrus in South Africa is exported (Citrus Growers' Association 2015). Thus, the control of T. leucotreta is crucial. Consequently, the citrus industry adopts a zero tolerance approach controlling the pest, being strongly reliant on integrated pest management (Moore & Hattingh 2012). Numerous control options are available, but are largely limited to use against the above-ground life stages of this pest: eggs, neonates and adults (Moore & Hattingh 2012; Grout & Moore 2015).

Numerous control options are available, but are largely limited to use against the above-ground life stages of this pest: eggs, neonates and adults (Moore & Hattingh 2012; Grout & Moore 2015).

- Description: Hsp90α/β, the signal transduction chaperone, maintains intracellular communication in normal, stem, and cancer cells. The well characterised association of Hsp90α/β with its client kinases form the framework of multiple signalling networks. GSK3β, a known Hsp90α/β client, mediates β-catenin phosphorylation as part of a cytoplasmic destruction complex which targets phospho-β-catenin to the 26S proteasome. The canonical Wnt/β-catenin pathway promotes stem cell self-renewal as well as oncogenesis. The degree of Hsp90α/β involvement in Wnt/β-catenin signalling needs clarification. Here, we describe the association of Hsp90α/β with GSK3β, β-catenin, phospho-β-catenin and the molecular scaffold, axin1, in the human MCF-7 epithelial breast cancer cell model using selective inhibition of Hsp90α/β, confocal laser scanning microscopy and immunoprecipitation. Our findings suggest that Hsp90α/β modulates the phosphorylation of β-catenin by interaction in common complex with GSK3β/axin1/β-catenin.

- Description: The COSATU Central Executive Committee met in its first session of the year over two days (5-6May 1998). The CEC received reports on a variety of issues and tool a number of policy decisions and approaches by on these matters. The CEC was characterised by anger and frustration on the scale of job losses in many industries and the failure of the current macro economic strategies to turn this tide around. Below are some of the issues discussed. The CEC endorsed the proposals submitted by Labour in NEDLAC on job 4^ creation in preparation for the Presidential Job Summit. The proposals will be further discussed in the coming Central Committee of COSATU scheduled for the 23-35 June 1998. COSATU shall use the Central Committee to further expand on the broad framework submitted in NEDLAC and get more proposals in line with how labour has categorised issues for the agenda of the Job Summit, i.e. (i) Measures to create jobs (ii) Measures to stop current job losses (iii) Measures to support the unemployed, (iv) Measures to assist the informal sector to be formal (v) Identification of long term issues to be negotiated beyond the Job Summit. COSATU is extremely concerned by the failure of both government and business to submit their proposals at NEDLAC. It is worth to note that various deadlines for them to submit proposals have passed. A million-dollar question is : Why does the government and business seem reluctant to submit their proposals? Clearly both government and business have abundance of capacity to deal with the proposals in a relatively short space of time. This is a major concern for COSATU. Whilst the delays continue, job losses are continuing unabated and the time bomb continue to click.

- Description: The common octopus Octopus vulgaris (Cuvier 1797) is a shallow-water cephalopod species that inhabits coastal rocky areas or reefs. It is the most studied and widely distributed species in its genus. This species has a short lifespan and a rapid growth rate of over 5% of body weight per day (García and Valverde 2006, Ibáñez and Keyl 2010). It is semelparous, with females laying large strings of eggs that they attach to the substrata in their dens (Hernández- García et al. 2002). There is a paucity of information on the preferred habitat and behaviour of O. vulgaris in its natural environment (Anderson 1997, Meisel et al. 2006). The species has been classified as highly mobile, yet resident individuals may exhibit high levels of territoriality. Its mobility allows it to move efficiently between a wide range of suitable habitats (Katsanevakis and Verriopoulos 2004). Octopus make use of both tactile and visual senses to forage, feed and seek suitable shelter (Forsythe and Hanlon 1997, Carvalho and Sousa Reis 2003, Rodríguez-Rúa et al. 2005). They are active feeders that seek out prey such as crustaceans, sessile molluscs and small fish (Forsythe and Hanlon 1997, Boyle and Rodhouse 2005), as well as their smaller conspecifics (Ibáñez and Keyl 2010). The majority of behavioural ecology studies on octopus have been on captive individuals. However, the activity patterns (Mather 1988), foraging strategies and aspects of the movement behaviour (Mather and O’Dor 1991) of juvenile O. vulgaris in the wild were described for an exploited population in Bermuda. Because intertidal octopus stocks are exploited by recreational, subsistence and artisanal fisheries (e.g. Oosthuizen and Smale 2003, Sauer et al. 2011), there are few opportunities to study the behavioural ecology of unexploited populations. An opportunity arose to study various behavioural patterns in an unexploited population in Baía dos Tigres, a large (~200 km2) coastal embayment situated on an isolated stretch of the southern Angolan coast (Figure 1). This study provides information on the population size structure, aspects of the movement behaviour, activity patterns and foraging strategies of O. vulgaris in this largely unstudied coastal embayment.
