Growth Impact and Determinants of Foreign Direct Investment into South Africa, 1956-2003
Get PDFThe paper is concerned with the growth impact and the determinants of foreign direct investment in South Africa. Estimation is in terms of a standard spill-over model of investment, and in terms of a new model of locational choice in FDI between domestic and foreign alternatives. We find complementarity of foreign and domestic capital in the long run, implying a positive technological spill-over from foreign to domestic capital. While there is a crowd-out of domestic investment from foreign direct investment, this impact is restricted to the short run. Further we find that foreign direct investment in South Africa has tended to be capital intensive, suggesting that foreign direct investment has been horizontal rather than vertical. Determinants of foreign direct investment in South Africa lie in the net rate of return, as well as the risk profile of the foreign direct investment liabilities. Policy handles are both direct and powerful. Reducing political risk, ensuring property rights, most importantly bolstering growth in the market size, as well as wage moderation, lowering corporate tax rates, and ensuring full integration of the South African economy into the world economy all follow as policy prescriptions from our empirical findings.

The paper addresses a multispecies systemic approach to uniting indigenous knowledge systems with earth jurisprudence and wild law using a systemic approach to storytelling and a range of mixed methods to develop rapport and relationships with participants who are members of an ongoing community of practice. The focus of this paper is on process and the space we have co-created through relationality. Our members pool diverse ways of knowing and being to focus on social, economic and environmental praxis to support multiple species. Ontologically and epistemologically we apply co-leaning to our praxis, and axiologically we assume that all transformative interventions should enhance fairness, transparency, and accountability as a basis for our case studies on risk reduction and the enhancement of wellbeing. The problem we are exploring in a forthcoming volume is whether pilot projects that put in place the principles of earth jurisprudence and organic farming (in partnership with members of PGS and the Wild Law institute) can make a difference to social and environmental justice. Our multidisciplinary and cross cultural team draws on indigenous knowledge systems as well as many other ways of learning and knowing through respectful dialogue to address our area of concern. Success is bench marked in terms of establishing a co-operative, the growing number of social enterprises striving to comply with organic farming principles, tree planting, seed collections for an organic seed bank and the perceived social, economic and environmental indicators of wellbeing. Our relational methodology applies participatory action research and storytelling to draw out themes which are mapped to assess progress towards re-generative living . Turning points for the better are indicated by a revised version of the UNSDG with a focus not on growth but on creating a cyclical economy that protects people and their shared multispecies habitat. To date our community of practice has managed to grow the number of participants and partners and our next goal is to set up two seed banks, one at the coast and one inland in South Africa in two case study areas in the Cape and Limpopo. This paper reflects on the process and methodology
“Digital Twins” in Education: Prospects and Reality
Get PDFThis article is aimed at understanding the revolutionary in meaning and “digital” in essence metamorphoses in education and the prospects for the emergence of a new educational network reality based on them. The focus of the discussion is not so much on digital innovations and transformations in education as such, but rather on the need to understand the possible prospects and results of these social network changes and modifications brought to life by the next stage of the digital revolution in education. It is proposed to include a wide range of network technologies and methodologies among the latest scientific and technological innovations taking into account the fact that the main focus of the work is on understanding the process / result of implementing the methodology of “digital twins” in education. Despite the fact that the latter is only at the beginning of its implementation in a broad educational context, the paper raises the question of the social consequences of implementing the methodology for constructing the latest network reality of “digital twins in education”, which has all the chances in the future to become a unique network of networks of “digital twins” of various social actors in education. The article discusses the managerial potential of developing and the difficulties of implementing the digital twin methodology, the expected effects of implementing the latter in education, and the socio-technological consequences of converting this technology into a new network educational reality in the Russian Federation
Redox flow batteries for hybrid electric vehicles: progress and challenges
No full textElectric vehicles have been the focus of muchresearch over the last two decades as the world has sought improved energy utilization and reduced emissions. However, the lengthy charging time, modest range and relatively sluggish
performance of batteries have restricted the commercialization of electric vehicles. Hybrid propulsion can overcome most of these shortcomings, with improved energy efficiency and reduced emissions compared to conventional internal combustion engine vehicles (ICEVs). Nonetheless, energy storage issues are still critical. Redox flow batteries (RFB), which continue to mature, have the potential to be fast recharging contenders. Refuelling is possible by rapid pumping of the reactants into the batteries’ tanks. Another feature of RFBs that makes them attractive for EV applications is the separation, in terms of physical location and sizing, of the energy and power components. This adds a
degree of flexibility that allows the optimization of the power and
energy components for a specific vehicle configuration and
performance. This paper concisely reviews RFBs and assesses their potential as a power source for hybrid electric vehicles. Experimental performance data from a 100 cm2 laboratory, unit cell, allvanadium redox flow battery (V-RFB) are presented. Based on these results, the size and performance of a V-RFB, suitable for a series hybrid electric vehicle, are estimated and compared with lithium-ion and conventional lead-acid alternatives. The results suggest that V-RFB performance could be improved to match that of the conventional lead-acid, with the added advantage of very rapid rechargin
The antinomies of aggressive atheism
Get PDFThe spate of popular books attacking religion can be seen as a manifestation of the recoil against the idea of multiculturalism. Religious identities are also cultural identities, and no meaningful form of multiculturalism is possible that leaves religion outside the sphere of public recognitiom. This paper argues that 'aggressive atheism' undermines its appeal to reason by refusing to see anything of value in religion. It also risks exacerbating cultural differences at a time when reconciliation is needed. The critique focuses on the contribution of Richard Dawkins and examines a number of tensions within the aggressive atheism of his best-selling book The God Delusion. The second part of the paper introduces an alternative, a framework of reconciliatory dialogues, between atheism and religion and within religious communities, operating not just at a formal or institutional level but also in cultural expressions and in the practices of everyday life
