This paper regards the knowledge flows between firms located on a science park as a type of network behaviour and answers three research questions: (1) What are the knowledge exchange behaviours of on-park firms? (2) Can we distinguish different types of behaviour among these firms?, and if so, (3) What are differences between these groups? We take a relational approach in which actor and relationship features are studied in a sample of firms located at the Innovation Hub (South Africa). Results show ...

This paper focuses on technological collaboration between small and large firms. It is argued that such collaborations can be beneficial for both types of partner, but that small firms often are confronted by the hazards of collaboration as these relationships are typically asymmetric. As a result of this, knowledge embodied in the dynamic (strategic, internal and external) capabilities of SMEs can flow unintentionally to the larger partner. If this occurs, the collaboration would be less successful ...

Human language technology (HLT) has been identified as a priority area by the South African government. However, despite efforts by government and the research and development (R&D) community, South Africa has not yet been able to maximise the opportunities of HLT and create a thriving HLT industry. One of the key challenges is the fact that there is insufficient codified knowledge about the current South African HLT components, their attributes and existing relationships. Hence a technology audit ...

Science parks are often established to drive regional economic growth, especially in countries with emerging economies. However, mixed findings regarding the performances of science park firms are found in the literature. This study tries to explain these mixed findings by taking a relational approach and exploring (un)intended knowledge transfers between new technology-based firms (NTBFs) in the emerging South African economy. Moreover, the innovation outcomes of these NTBFs are examined by using ...

We report on an attempt to identify the major determinants of innovation in manufacturing and non-manufacturing firms in South Africa. Results are reported using data collected within the framework of the South African Innovation Survey of 2001. This theorybased exploratory, empirical research shows that innovative outcomes are influenced by the extent to which firms have internal knowledge resources and use internal and external knowledge and information sources. However, results differ for sub- ...

ENGLISH ABSTRACT: Business enterprises are under increasing pressure to become internationally competitive due to globalisation. World-class companies from abroad can now easily compete with local companies, introducing high quality products and services to the local community and industry. The pace of technological change is also forcing companies to increase productivity and to become more cost effective. Performance management is part of the strategic management process in the business enterprise ...

ENGLISH ABSTRACT: The search for consensus on spent fuel management (SFM) strategies in the nuclear industry has become complex, not least in the South African context. This study identifies three SFM options: reprocessing-and-recycling, direct disposal, and indefinite storage. From the contentious issues surrounding the SFM options, a framework for evaluating the options and selecting a preferred SFM option for South Africa is proposed. It consists of evaluation criteria categorised into nine dimensions: ...

Innovation is widely recognized as a driving force behind economic growth. Despite its importance, not much is known about the innovative behaviour of South African firms. In the study reported here, we compare South African companies with their counterparts in the European Union. A representative sample of 617 South African firms answered questions about their innovative behaviour in the period 1998 - 2000.We found that innovation outputs, the percentage of innovating businesses, were comparable ...

Modern technology plays a key role in the ability of manufacturing enterprises to compete as world class manufacturers. Managers need to make complex decisions regarding applicable technologies in order to gain optimal return on technological investment. A model was developed to assess the impact of manufacturing technology on the productivity and competitiveness of the enterprise. The approach taken by the model is to view the manufacturing enterprise as a manufacturing system in which different ...

In this paper we test whether the use of a set of technology management tools (TM-tools), a specification of alliance portfolio capability, influences the relationship between alliance portfolio diversity and a firm's innovation outcomes. With this model, we add to the theoretical literature on the performance effects of alliance portfolio diversity and specific contingencies allowing to appropriate benefits from this diversity. Based on a sample of South African firms, we first confirm the inverted ...

This challenging nature of project-to-project knowledge transfer led to the proliferation of a host of tools and instruments (so-called knowledge transfer mechanisms) in which little structure can be discovered making selection by (project) managers a difficult task.Aim: This article aims to deal with this ...

Forensic facial comparison (FFC) is a scientific technique used to link suspects to a crime scene based on the analysis of photos or video recordings from that scene. While basic guidelines on practice and training are provided by the Facial Identification Scientific Working Group, details of how these are applied across the world are scarce. FFC is frequently used in South Africa, with more than 700 comparisons conducted in the last two years alone. In this paper the standards of practice are outlined, ...

As a measure of immediate remedy Eskom has turned to demand side bidding (DSB), a methodology whereby the demand side has an opportunity to sell back flexible load to the supply side. This paper assesses DSB with the aim of evaluating and gauging the current and potential future standing of DSB as a technology ...

Power losses are an important phenomenon in type-2 superconductors. Precise evaluation of power losses in superconducting coils is crucial for designing novel machines such as superconducting motors or generators. Although ac losses are relatively easy to measure with electrical methods, it is more difficult to measure power losses in the dc mode, which is induced by varying external magnetic fields, such as in a real operating environment. In particular, the problematic one could be the direct- ...
