Description: There are many classroom teaching approaches available, but they generally all have one fundamental commonality: they require some form of human communication. As human communication is subject to several perceptual errors in both listening and seeing, there are challenges imposed on the success of the communication. The ability of the teacher and the students to communicate effectively with each other is a factor for the success of each reaching their goals. The teacher imparts his/her knowledge in the classroom, but as von Foerster reminds us: “It’s the listener, not the speaker, who determines the meaning of an utterance” (Glasersfeld, 2007); for the listener contextualises this information based on their own past lived experience. Thus, the student’s epistemology and their expression of their understanding is integral in the classroom context. This position paper presents a cybernetic approach to the teacher-learner system, challenging traditional ideas about the role of each actor within the system, with special attention given to Pask’s (1976) Conversation Theory and its fit for purpose in a contextual learning system.

Description: Functionally graded materials (FGMs) are advanced materials with improved properties that enable them to withstand severe working environment which the traditional composite materials cannot withstand. FGM found their applications in several areas which include: military,medicine and aerospace. Various manufacturing processes are used to produce functionally graded materials that include: powder metallurgy, physical vapour deposition, chemical vapour deposition process and laser metal deposition process. Laser metal deposition (LMD) process is an additive manufacturing process that can be used to produce functionally graded material directly from the three dimensional (3D) computer aided design (CAD) model of the part in one single process. LMD process is a fairly new manufacturing process and a highly non-linear process. The process parameters are of great importance in LMD process and they need to be optimized for the required application. In this study, functionally graded titanium alloy composite was produced using optimized process parameters for each material combination as obtained through a model that was developed in an initial study and the FGM was characterized throughmetallurgical, mechanical and tribological studies. The results showthat the produced FGM has improved properties when compared to those produced at constant processing parameters for all material combinations.

Description: As “green” issues continue to become a global concern in the manufacturing supply chain, developing appropriate performance measurement systems for specific supply chains is imperative. Various green supply chain management strategies have been proposed in different contexts. On the other hand, a number of performance management systems (PMS) have been proposed. However, given the variations in the contexts of the available green strategies and the performance measurement approaches, selecting or developing suitable performance measures and the ensuing PMS under a given supply chain context is not trivial. The purpose of this study is to develop a structured taxonomic approach to developing PMS under various green supply chain conditions, contexts, and business objectives. Therefore, we (i) explore extant empirical studies on green supply chain activities and environmental management, (ii) develop a taxonomy of green supply chain strategies, (iii) derive a structured approach to developing green performance management systems, and, (iv) provide a taxonomic performance measurement framework consisting of environmental, economic and social performance metrics. Unlike past studies, the taxonomic framework forms a practical platform to assist decision makers when developing a suitable set of performance measures and the ultimate PMS while considering the particular context of specific green strategies under which the PMS is supposed to operate.

Description: The UJ SARCHI Chair: African Diplomacy and Foreign Policy in partnership with the UJ Library invites you to meet Tony Leon, the author of the book Opposite Mandela: Encounters with South Africa’s Icon About the book: Opposite Mandela relates the untold stories of how South Africa’s first democratic president related to his political opponents. Insightful, and simultaneously serious and amusing, it lifts the veil on many unknown or unexplained benchmarks from that era: the personal animosity between Mandela and FW De Klerk, the decision of the Democratic Party to reject Mandela’s offer of a seat in his cabinet and whether the extraordinary outreach of Mandela to the minorities was the shrewd calculation of a latter-day Machiavelli or the genuine impulses of a secular political saint. This highly readable and first-hand account considers in a balanced manner both the golden moments and the blind spots of one of the most consequential presidencies and leaders of the modern democratic age. About the author: Tony Leon was a member of the South African Parliament for nearly 20 years, for 13 of those leading the Democratic Alliance. He subsequently served as South Africa’s ambassador to Argentina, Uruguay and Paraguay from 2009 to 2012. FACILITATOR Prof Chris Landsberg, University of Johannesburg

Description: Laser material deposition process is an additive manufacturing technology that is used to produce functional parts directly from the three dimensional (3D) model of the part. It offers a lot of advantages in the surface modification of components, in the repair of existing worn parts, as well as for building parts that is made up of composites and functionally graded materials. This is possible because the laser metal deposition process can handle more than one material simultaneously. Processing parameters are of great importance in achieving the desired properties. Ti6Al4V is the most widely used titanium alloy in the aerospace industry. This is because of its excellent properties. However, the wear resistance behavior of these materials is not impressive because of the surface damage that occurs when they are used in applications that involves contact loadings. In this study, the effect of laser power and scanning velocity on the microstructure, the microhardness and the wear resistance properties of Ti6Al4V/TiC composites has been thoroughly investigated in order to optimize these process parameters. The Ti6Al4V/TiC composites were laser deposited with a composition ratio of 50 W% Ti64 and 50 W% TiC and at 50% overlap percentage. The laser power was varied from 1 to 3.8 kW and the scanning speed was varied between 0.03 and 0.1 m/s. The results shows that the optimum process parameters is at a laser power of about 2.0 kW and the scanning speed of about 0.055 m/s.

Description: Africa’s external debt rose sharply between 1970 and 1980 and between 1980 and 2007. A small decrease could be observed after 2007 under the Heavily Indebted Poor Countries (HIPIC) and the multilateral debt relieve initiatives (MDRI) in 2006. The debt cancellation under these initiatives was meant to generate between 25 to 30 billion US Dollars per year for economic and human development. However, were these funds properly invested for the purpose for which they were borrowed, meaning reducing poverty by investing on human capital and infrastructures to ignite economic growth? Using a regression analysis, the initial findings reveal that, Gabon struggled to sustain its debt beside the HIPIC and the (MDRI) strategies. The paper starts by introducing a problematic related to the state of debt and poverty in Africa, followed by a concise review of literature and a detailed research method from which appropriated findings were generated. The paper proceeds by compiling comprehensive recommendations followed by a conclusion.

Description: The cost of Marketing in a company is so critical that, marketing become costly in International Business, especially when devaluation hit a local currency. The primary purpose of this study is to find the impact of devaluation on trade balance in Zimbabwe using the Johansen-Juselius Co integration and Vector Error Correction Model (VECM), unit root tests, and impulse response analysis. Quarterly data for the period 1990 to 2005 is used. The result shows that devaluation is effective in improving trade balance in the long run and there is a co integrated relationship between the real effective exchange rate and trade balance in the long run. The findings initially revealed that there is a long run relationship between trade balance and exchange rate. Secondarily the real exchange rate is an important variable to the trade balance, and that devaluation will improve trade balance in the long run, thus consistent with the Marshall-Lerner condition and finally, the results indicate no J-curve effect in Zimbabwe.

Description: In recent years, foreign remittances have become a major source of external development finance. In the past decade, Nigeria has become the single largest recipient of foreign remittances in Sub-Saharan Africa, receiving between 30 to 60 percent of flows into the region. However, because of the conventional view that the bulk of household income from foreign remittances is used particularly for consumption purposes, their deliberate investment by some recipients in the rural nonfarm economy (RNFE) has not yet undergone rigorous econometric analyzes. The thrust of this paper is to estimate the impact of foreign remittances on the RNFE of the Igbos of Southeast Nigeria, using sample data from foreign remittance-receiving households engaged in rural nonfarm income-yielding investments. Key findings from the regression analysis show that households’ ratio of foreign remittances invested in rural nonfarm activities (RNFA) to the total amount of foreign remittances received by them tend to decrease with the increase in remittances received. There is, however, a positive correlation between remittances and expenditure on the rural nonfarm sector. The remittance elasticity for investment in the sector and the marginal foreign remittances share confirm that foreign remittance-receiving households spend a higher proportion of remittances on profit-oriented RNFA.

Description: This article set out to explore the impact that governance has on the developmental role of Public Enterprises in Africa. However initial findings revealed that, the above failure is related to lack of leadership, maladministration and corruption which are the enemies of good governance, the State and of National Development Plan (NDP) as these impede any development initiative. This paper is divided into five major parts. The first part introduces the problematic of the research; the second part argues about the concept of governance, the third part discusses public enterprises reforms and the justification for decentralisation as a tool for the sustainability of public enterprises. The fourth part explains the impact of decentralisation on SOEs. The Fifth part concludes and presents a set of recommendations for future research.

About the book: The struggle of the generations before that of the Born Frees was a struggle for political freedom and democracy, and was the foundation for revolution and reform but not the ultimate goal. Malaika contests the notion of the born-free generation when it is a generation that was born in the midst of a struggle for economic freedom and the quest for the realisation of the objectives of the African Renaissance. Now 22 years into a democratic dispensation, Malaika describes her life as having been a struggle to understand the “rainbow nation” and to salvage from it something that renders her free. About the author Malaika Wa Azania, a fierce debater and an activist devoted to pursuing the African Renaissance agenda is the founder of a pan Africanist journal, African Voices of the Left and a columnist for The Thinker magazine. In 2012, Malaika was the branch secretary of the South African Students Congress (SASCO) at Rhodes University in Grahamstown and is currently the Secretary General of the African Youth Coalition, an umbrella organisation of all the youth society organisations throughout the African continent.
