Changes in biochemical quality and cyanogenic safety in flours from different cassava varieties grown within the South-eastern African region as influenced by processing technique were investigated. Two local (Mweulu and Tanganyika) and four improved…

This paper explores four Item Response Theory (IRT) models to determine the most appropriate for understanding item non-response. The selected IRT model was used to identify among five categories of survey questions, the most difficult to answer by…

After reviewing the theoretical and empirical literature on Item Response Theory (IRT) and Item-non response, this study investigates three issues: Firstly, to identify the most appropriate IRT model for understanding item-non response...

Survey research has been widely used in public opinion research in Ghana. Ghanaian researchers are happy about data richness and they are also concerned about data quality. In this paper Item Response Theory (IRT) has been used to identify the most…

Studies were conducted to evaluate the combined effects of spontaneous fermentation and amylase-rich flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2 × 3 × 3 factorial design,…

The aim of this study was to assess the macrobenthic fauna structure and use its indices as a tool for characterizing the ecological state of the Laloi lagoon. Thus, a field assessment of the benthos in the Laloi lagoon was carried in January 2012.…

This paper seeks to present a proposed linear programming model to determine the best hectare allocation for optimum crop production to ensure food security and reduce poverty among farmers in the region. Five selected crops in fifteen sampled…
