Enterprises operating at the Base of the Pyramid (BoP) find it difficult to simultaneously achieve economic (profitable growth) and social (poverty alleviation) outcomes. This study builds on a previously published systematic literature review that identified the key growth-promoting factors of the Small, Medium, and Micro Enterprises (SMMEs) operating in this space. A Grounded Theory Approach was followed to identify six core focus areas, which form the basis of a practical framework to evaluate SMMEs at the BoP, namely: Business modelling; business strategy; innovation; marketing; strategic alliances; and sustainable development. Expert screening interviews were conducted to evaluate the framework for credibility and confirmability. Thereafter, 57 for-profit South African enterprises were surveyed to empirically explore how SMMEs view and implement these framework components. The outcome of the study is a validated high growth-promoting BoP portfolio framework against which SMME owners can evaluate their enterprises to identify areas of growth and development.
Development projects aim to make a difference in communities. Funders often require that the intervention needs to last, or that it needs to effect change that will last, over an extended period of time. In short, a sustainable difference needs to be made and this is an important measure of success. However, there are inherent drivers in the combined system of donors and beneficiaries that counter sustainability. This article explores these drivers, and identifies project design elements that need to be in place in order to promote sustainability by countering the drivers. This approach is applied to an education project, and implications for ICT4D projects are developed.
The increasing global focus on sustainability is bringing the question of the sustainability of transport systems-which are still exhibiting numerous negative effects as evidence of their unsustainability-to the fore. While sustainability is an often-discussed concept, tools to guide the practical implementation thereof are limited. This paper presents a framework for an inventory of indicators against which to measure the sustainability of transport systems. While the framework is validated for urban transport systems for increased mobility (here referenced as microtransit systems), the concept is investigated in the context of transport systems in general. A systematic review of the literature was used to develop a framework of 12 areas and 50 indicators of sustainability. Expert reviews, an Analytical Hierarchical Process (AHP), and an Equally Weighted Average (EWA) method were employed to allocate weights to the indicators and to validate the framework for microtransit systems. The framework contributes to the literature by identifying, categorizing, and integrating concepts related to sustainability in transport systems. It is intended to aid short-term decision-making in the design of urban transport systems, to continuously monitor the long-term progress of transport systems against sustainability goals, and to guide policy development. Future work would include enhanced empirical validation of the framework in the context of other types of transport systems, beyond microtransit.
The indirect effects of mastitis treatment are often overlooked in cost-benefit analyses, but it may be beneficial for the dairy industry to consider them. The cost of mastitis treatment may increase when the duration of intra-mammary infections are prolonged due to misdiagnosis of host-adapted mastitis. Laboratory diagnosis of mastitis can be costly and time consuming, therefore cow-side tests such as the California Milk Cell Test (CMCT) and Milk Electrical Resistance (MER) need to be utilised to their full potential. The aim of this study was to determine the relative benefit of using these two tests separately and in parallel. This was done using a partial-budget analysis and a cost-benefit model to estimate the benefits and costs of each respective test and the parallel combination thereof. Quarter milk samples (n= 1860) were taken from eight different dairy herds in South Africa. Milk samples were evaluated by means of the CMCT, hand-held MER meter and cyto-microbiological laboratory analysis. After determining the most appropriate cut-off points for the two cow-side tests, the sensitivity and specificity of the CMCT (Se= 1.00, Sp= 0.66), MER (Se= 0.92, Sp= 0.62) and the tests done in parallel (Se= 1.00, Sp= 0.87) were calculated. The input data that were used for partial-budget analysis and in the cost-benefit model were based on South African figures at the time of the study, and on literature. The total estimated financial benefit of correct diagnosis of host-adapted mastitis per cow for the CMCT, MER and the tests done in parallel was R898.73, R518.70 and R1064.67 respectively. This involved taking the expected benefit of a correct test result per cow, the expected cost of an error per cow and the cost of the test into account. The CMCT was shown to be 11%more beneficial than the MER test, whilst using the tests in parallel was shown to be the most beneficial method for evaluating the mastitis-control programme. Therefore, it is recommended that the combined tests should be used strategically in practice to monitor udder health and promote a pro-active udder health approach when dealing with host-adapted pathogens.
Despite progress towards improved cooperation within the Southern African Customs Union (SACU), it can be argued that real economic integration is still lacking. Cross-border value chain (VC) development has been proposed as a potential enabler of regional economic integration. This article draws on a systems thinking process to explore the dynamic process of regional economic integration and value chain development. Through an inductive approach, we consider pathways for value chain development using the agro-processing and automotive sectors within SACU as case studies. The outcome of the dynamic hypothesis is to inform a framework for strategic decision-making to support policy action towards developing cross-border value chains in SACU. OPSOMMINGTen spyte van vooruitgang in beter samewerking binne die SuiderAfrikaanse Doeane-Unie (SADU), kan dit aangevoer word dat ware ekonomiese integrasie nog ontbreek. Die ontwikkeling van oorgrenswaardekettings word beskou as 'n moontlike drywer van plaaslike ekonomiese integrasie. Hierdie artikel maak gebruik van 'n stelseldenke proses om die dinamiese proses van streekswye ekonomiese integrasie en waardeketting ontwikkeling te ondersoek. Ons gebruik 'n induktiewe benadering om roetes tot waardeketting ontwikkeling deur middel van gevallestudies in landbou-verwerking en die motorsektor, te ondersoek. Die uitkoms van die dinamiese hipotese is om 'n raamwerk te ontwikkel om strategiese besluitneming en beleidsaksie vir die ontwikkeling van oorgrenswaardekettings in SADU te ondersteun.
