Promoting smallholder farmers’ adoption of modern agricultural production technology is one effective way to improve the capabilities of smallholder farmers. This paper aims to explore the impact of Internet use on the adoption of agricultural production technology by smallholder farmers based on a survey of 1 449 smallholders across 14 provinces in China. The results suggest that Internet use can significantly promote technology adoption, with the probability of adopting new crop varieties, water-saving irrigation technology and straw-returning technology increasing by 0.200, 0.157 and 0.155, respectively. Furthermore, the effect of Internet use is found to be heterogeneous with a greater effect on smallholder farmers having low education levels, limited training, and high incomes. To increase agricultural production technology adoption by smallholders, rural Internet infrastructure and Internet use promotion should be the focus for the Chinese government.展开更多

As teenagers are in a complicated period of development, parents struggle in supervising their use of the intemet. This study takes the teenagers' standpoint and explores how the teenagers perceive their parents' involvement in their Internet use. Survey was conducted towards teenagers in the UAE, which has the highest penetration of digital devices in the Gulf region as well as one of the highest in the world. The results showed that girls usually receive more supervision fi'om parents than boys. The older the teenagers are and the more they depend on the Internet, the more they perceive parents' supervision to be beneficial. However, not enough supervision has been given to those who access the Internet more frequently. The findings indicate more parents' supervision is needed from the teenagers' point of view. Discussions are made from psychological and socio-cultural perspectives and suggestions for future research are presented.展开更多
