Research question/issue:This study examines whether geographic proximity produces a proximity preference as interlocking firms observe each other and learn innovative behaviors through information transmission among interlocking *** findings/insights:We study the performance of A-share-listed companies in China from 2007 to 2017 on the basis of resource dependence theory,agglomeration effect theory,and Porter’s competitive *** target firms learn about research and development–related innovation behaviors from interlocking firms closer to them,they experience more efficient learning effects and have improved convergent ***,this proximity advantage increases the willingness of the target firm to communicate with and learn from interlocking firms closer to *** developed areas and research and development–intensive industries positively affect the learning efficiency of interlocking ***/academic implications:Our conclusion is consistent with resource dependence theory;target firms in highly developed areas are more willing to imitate and study nearby interlocking firms to maintain their peer relations,innovation potential,and *** conclusion is also consistent with competition theory,which states that the exchange of information between target firms in highly research and development–intensive industries and distant interlocking firms increases innovation differentiation,innovation potential,and competitiveness,even when such exchange has a high ***/policy implications:The results support resource dependence theory and peers’*** information obtained by interlocking directorates through external social relations guides firm decision-making,and closer distances reveal more obvious effects.

By periodically aggregating local learning updates from edge users, federated edge learning (FEEL) is envisioned as a promising means to reap the benefit of local rich da?ta and protect users'privacy. However, the scarce wireless communication resource greatly limits the number of participated users and is regarded as the main bottleneck which hin?ders the development of FEEL. To tackle this issue, we propose a user selection policy based on data importance for FEEL system. In order to quantify the data importance of each user, we first analyze the relationship between the loss decay and the squared norm of gradi?ent. Then, we formulate a combinatorial optimization problem to maximize the learning effi?ciency by jointly considering user selection and communication resource allocation. By problem transformation and relaxation, the optimal user selection policy and resource alloca?tion are derived, and a polynomial-time optimal algorithm is developed. Finally, we deploy two commonly used deep neural network (DNN) models for simulation. The results validate that our proposed algorithm has strong generalization ability and can attain higher learning efficiency compared with other traditional algorithms.

CAI (Computer-Assisted Instruction),a kind of teaching methodology characterized by modern technology,has become a possibility in the application of modern education. CAI in ELT can provide various teaching environments and diverse study patterns which traditional teaching can not achieve. This paper mainly introduces the importance of CAI and discusses its effective use in ELT. As a newly developed technique,CAI is either a challenge or an opportunity for our teachers. If we can grasp this chance properly,our English teaching will surely have a bright future.
