It is a subject at the intersection of three disciplines: jurisprudence and legal philosophy, constitutional law and power politics, and civil-military relations, i.e. military security policy which is one aspect of national security policy.2 The subject is of interest in at least four aspects: (i) it problematises the inescapable question of governance in the African continent; (ii) it challenges the democratization agenda in Africa - how does one democratize not only political governance but also the instruments of violence in the state? (iii) it challenges African constitutional lawyers and policy makers to seek a constitutional model that addresses the enduring menace of the power of the gun in African affairs and the changing role of the military in African politics; and (iv) it underscores national security and sovereignty concerns.

I will argue that an important reason for the failure of curriculum implementation could be ascribed to a relative neglect by policymakers of “teacher landscapes” or the beliefs teachers have about teaching. I will argue that it “matters what teachers think and do” and if policymakers do not take account of this reality, successful curriculum implementation will remain a challenge.

Colonial tales, alter-narratives and the enduring value of anthropology

- Description: Stories and story-telling are fundamental to human beings. What stories do we choose to tell, hear and relate? From childhood through to adulthood, stories and story-telling provide social content, example, advice, therapy, continuity, connection and entertainment. Story-telling is also a space for hidden resistance, embodiment and the invocation of rank. Accompanied by song and dance, those intangible heritages which must remain dynamic to endure, stories facilitate an aural and oral community that engenders its own understanding of time, place and identity. In anthropology, the study of humanity in all its complexities, there is the collection, collation and retelling of stories for audiences who would otherwise not understand or seek to essentialise those deemed ‗other‘. In this inaugural lecture I focus on the value of stories gathered from anthropological field research in the southwest Indian Ocean Islands. The stories (often constitutive of a multiply-situated self), shed light on the finer details of gendered, ethnic and raced existence in the island communities. They also offer deep insight into the nature and possible ‗evolutions‘ of contemporary societies. Finally, I suggest that alter-narratives, those stories rarely told, provide access not only to multiple worlds, they are part of an aural epistemology which might lead to alternative ways of connecting with others and thereby conceptualising and articulating identity in our contemporary global society.

I will present a brief history, look at the approaches that have been followed by scientists and engineers to develop and understand small things, and summarise some of the benefits to society in terms of new materials and processes, energy storage and generation, electronics, environmental applications, medicine and transportation. Since our own research focuses on the development on semiconductors, I will conclude the scientific part of the presentation by considering the contribution of semiconductors to the development of nanotechnology and highlight a few examples from our own research during the past two decades on the development of nano-scale semiconductor structures, like nanorods, quantum wells and superlattices.

What is new are the changing physical circumstances of the world in which we live, which mean that human society can no longer afford to analyse ourselves and our social, political and economic systems independently of the natural world.

- Description: idea for the paper emanated from my concern regarding the absolute flood of unethical behaviour in recent times. Fraud and corruption in South Africa is rife and it seems that the average person has no control over what comes next. Considering the impacts of peoples’ background, social standing and culture, the paper considered the psychological processes through which learning of habits and mannerisms take place; and how it influences ethical behaviour. Valuable lessons are learnt, namely that culture, whether it being ethnical, organisational, family or religious, have a direct impact on a person’s ethical value system and subsequently on whether a person is inclined to partake in fraud and corrupt activities. Fraud and corruption can cripple and destroy organisations and its auditors. Fraud and corruption are costly. The paper reports that it is ultimately the responsibility of executive management to manage fraud and associated risks – management must set the “Tone at the Top”. Managing ethics is costly, but ignoring it is fatal. Although it is not the primary responsibility of auditors to detect and investigate fraud and corruption, the accounting profession needs to do introspection to determine what society expects of them. A mere audit opinion on annual financial statements does not satisfy the demands of society any more. The question is apparently not whether fraud will occur in organisations, but rather when and that everybody must insist on doing the right thing – for the greater good.

A local failure on the surface usually causes the entire component to be rejected or it may lead to a failure of a machine or structure. It is estimated that in developed countries, the loss caused by corrosion is up to 2-4% of gross national product [1]. Thus, many countries have made great efforts to improve the surface performance of parts in order to enhance the reliability of mechanical equipment and prolong their service life.

- Description: Nature in its essence is frequently viewed as a thing of beauty and the ultimate truth of perfection. Unfortunately, this view of nature is often undermined when it comes to the concept of women in confinement and labour. Women, naturally by virtue of being females, have the capacity to become pregnant and thus to bear children. However, in many instances this capacity becomes limited, or misunderstood. In such cases, humans start viewing or considering confinement and labour in terms of ‘being wrong and incorrect’. They only see issues around age and marital status while losing sight of the fact that nature has ordained that all women have a uterus, which has a potential to conceive, but under ‘suitable’ conditions. Yes, the uterus does not know about age and health restrictions, but will expel its contents when the time comes, and suitability around that expulsion unfortunately becomes the concern of humans (midwives or family members). Very often young girls who are in confinement are received and treated differently by these two categories of humans because they are deemed not to be at the correct age for falling pregnant and to be in labour, or they are regarded as having been ‘naughty’.

- Description: Interest in the use of low-valent titanium species as reagents in organic synthesis began with Van Tamelen and his research team in 1965, when they reported the first ever low-valent titanium-induced reductive dimerization of alcohols to give hydrocarbons [1]. In the early seventies shortly after the Van Tamelen report, the research teams of Mukaiyama,[2] Tyrlik[3] and McMurry[4] made the independent and simultaneous discovery that ketones and aldehydes undergo reductive dimerization to yield olefins on treatment with low-valent titanium reagents. Particularly McMurry and his co-workers [5,6,7] have extensively investigated this reaction, therefore this process is now generally referred to as the “McMurry reaction”.

The Plastic University: Knowledge, Disciplines and Decolonial 'Circulations'

- Description: The university is as plastic as the social figure of ‘Mandela’ after whom it is named. It is as plastic as the globe and its humanity in whose name it exists. And, it is as plastic as the human subject that is ‘perpetually called on to reconfigure itself in relation to the artefacts of the age’, as Mbembe2 argues in Critique of Black Reason. The very nature of addressing, of writing … of inaugurating … oneself, through an address is an act of reconfiguration, of responding to an artefact of the university and the professoriate. It is, when all is said and done, a performance, a performative act: declaring so and so a professor of this or that status, authorizing ‘it’ to utter something with some kind of formative force.
