This study assessed the mediating role of green competence in the relationship between digital orientation and green innovation performance among Chinese manufacturing firms. This study gathered data from 227 manufacturing firms located in the Jiangsu Province of China. Data were gathered using a structured questionnaire and analyzed using a covariance-based structural equation modeling in Amos (v.23). The findings revealed that digital orientation had a direct effect on manufacturing firms’ green innovation performance. This study also reveals that digital orientation had a direct positive effect on green competence. Also, green competence had a direct effect on green innovation performance. Finally, it was identified that green competence partially mediated the relationship between digital orientation and manufacturing firms’ green innovation performance.

The objective is to assess the variability of collateral crypto-assets used in secured lending on the blockchain. Using the coefficient of variation, the study estimates volatility of selected assets and implied risk intensity for both borrowers and lenders on blockchain-based lending. The coefficient of variation model was adopted by testing volatility. The model produced a number of key empirical observations from January 2017 to December 2018 reflecting market swings resulting in volatility, despite its simplicity, using Bitcoin, Ethereum and Ripple crypto-assets. The results of the study provide clarity on the crypto-assets bullish and bearish markets and whether there is a correlation between crypto-assets and Bitcoin market dominance. The recommendations include that financial institutions should de-risk their investment, participate in the crypto-currency domain and ensure financial inclusion; concepts of traditional asset-backed lending could be implemented by looking at 50 percent loan-to-value ratio.

The potential for sorghum to be the driver of economic development in Sub-Saharan economies, including South Africa, is enormous. However, there has been a notable decline in the production, use, and consumption of sorghum due to the changes in preferences and lifestyle of its consumers in Southern Africa. While existing and extant studies have studied the benefits and impacts of sorghum on the African economy, there is an inadequate understanding of the feasibility of sorghum farming in South Africa using Garrett’s ranking technique. As a result, this study explores the feasibility of sorghum farming in the Nyoni area of KwaZulu Natal, South Africa. Hence, a survey was conducted with a sample size of 150 respondents that were purposively selected. An interview schedule was also used to collect primary data, and the data were analyzed using Garrett’s ranking technique. The results of this study indicated that edaphic factors, climatic factors, volatile markets, information transfers, education, drought resistance variety, access to credit, and technological advancement were critical in making sorghum farming feasible in the Nyoni area of KwaZulu Natal. Therefore, this study recommends that there is an overarching need to explore the feasibility of sorghum farming, starting at a smaller scale until a more stable state of marketability and potential profitability has been established.
