    Sammanfattning : Ghana as a rapidly growing and urbanizing middle-income country is facing a number of challenges, including (1) implementing a sanitary, environmental-friendly, and economically-sound waste management system; (2) increasing its agricultural productivity in a sustainable way to meet the growing domestic food demand; and (3) providing livelihood opportunities in both rural and urban areas. Using the black soldier fly (BSF), a particularly beneficial insect, to locally and cost-effectively valorise abundant, high-impacting, and nutrient rich organic waste streams, such as food waste (FW) and faecal sludge (FS), into affordable and sustainable farming inputs like organic fertilizer and animal feed products, could tackle all these challenges at the same time.

    Sammanfattning : The main purpose of this study was to compare how the Step-by-Step™ (S-b-S) and the newly developed How Was School Today (HWST) prototype can support participation in narrative activities for a 10-year-old boy with complex communication needs (CCN) when he interacts with two typically developed peers. The researchers wanted to find out how the use of the different communication aids affected interaction. LÄS MER
