In BOP ventures the notion of “selling to the poor” has steadily been replaced by business approaches that suggest sustainable value creation. This has certain implications, in particular the development of strategies that serve triple bottom-line goals. These include economic, social and environmental benefits, in other words, the well known goals of people-planet-profit. However to optimise value-creation one ideally needs to follow a strategy that is based on some form of conceptual model that can serve as a frame of reference. This paper proposes such a conceptual model. The research was undertaken in 8 BOP projects involving multinational information and communication technology companies in Africa. ICT is relevant here because of frequently high expectations that it contributes positively to development goals. A study of the BOP literature reveals that several elements need consideration when trying to create value in developing areas. In addition it emerges that these elements are somehow interdependent. Using information found in the literature as guide a study of 8 cases was undertaken. The research approach was the case study method and the data was analysed for emerging patterns. Primary and secondary data was collected through interviews as well as a close study of archival and other sources. The analysis revealed three high level factors that may need to be aligned in order to ensure optimised value creation of BOP ventures. These three factors are BOP strategy, partnerships, and products & services development. It is also confirmed that neither BOP strategy nor partnerships nor products/service development can be synthesised independently from the rest. There is a delicate balance and interaction between the three where all three are interdependent and mutually influence each other.

This study proposes a systematic value chain approach to helping businesses identify and eliminate inefficiencies. The authors have developed a robust framework, which food-sector entrepreneurs can use to increase profitability of an existing business or to create new profitable opportunities. The value chain approach provides win-win opportunities for players within the value chain. To test the robustness of the framework, the authors use food waste as an example of a critical inefficiency and apply it to two different food sector business cases, each operating in diverse conditions. Because the suggested framework addresses the core elements and parameters for the existence and competitiveness of a business, the model can be adapted to other sectors.

Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate and compare arithmetic means of histograms and case-value plots? We designed four item types: two requiring mean estimation and two requiring means comparison. Analysis of gaze data of 50 students (15–19 years old) solving these items was triangulated with data from cued recall. We found five strategies. Two hypothesized most common strategies for estimating means were confirmed: a strategy associated with horizontal gazes and a strategy associated with vertical gazes. A third, new, count-and-compute strategy was found. Two more strategies emerged for comparing means that take specific features of the distribution into account. In about half of the histogram tasks, students used correct strategies. Surprisingly, when comparing two case-value plots, some students used distribution features that are only relevant for histograms, such as symmetry. As several incorrect strategies related to how and where the data and the distribution of these data are depicted in histograms, future interventions should aim at supporting students in understanding these concepts in histograms. A methodological advantage of eye-tracking data collection is that it reveals more details about students’ problem-solving processes than thinking-aloud protocols. We speculate that spatial gaze data can be re-used to substantiate ideas about the sensorimotor origin of learning mathematics.
