These networks can be viewed as a collection of nodes and edges, where users and their interactions are represented as nodes and the connections between them as edges. Understanding the factors that contribute to the formation of these edges is important for studying network structure and processes. This knowledge can be applied to various areas such as identifying communities, recommending friends, and targeting online advertisements. Several factors, including node popularity and friends-of-friends relationships, influence edge formation and network growth. This research focuses on the temporal activity of nodes and its impact on edge formation. Specifically, the study examines how the minimum age of friends-of-friends edges and the average age of all edges connected to potential target nodes influence the formation of network edges. Discrete choice analysis is used to analyse the combined effect of these temporal factors and other well-known attributes like node degree (i.e., the number of connections a node has) and network distance between nodes. The findings reveal that temporal properties have a similar impact as network proximity in predicting the creation of links. By incorporating temporal features into the models, the accuracy of link prediction can be further improved.展开更多

Many ecological economists have criticized the blind pursuit of short-term economic interests in the last 30 years for leading to loss of natural capital and ecosystem services. This study demonstrates the concept of?“uneconomic growth”?by measuring the actual costs of fishing activities and fishery policy implemented in China’s Pearl River Estuary from economic, social, and ecological aspects. The results show that the costs of economic growth exceed the benefits of additional growth because of the limits of the ecosystem. The ecological system of the Pearl River Estuary has been degraded significantly by overfishing and is regarded to be under non-optimal conditions regarding both ecological and socio-economic objectives.展开更多

In this novel, Twain not onlydescribes the courageous adventures of Huck, but also his psychological or spiritual growth. Due to the social and cultural back-ground of that time and general cultural concept the protagonist was instilled before, the conflicts of the protagonist's self-con-sciousness appear many times in this novel when the issue of slavery is concerned. However, through the protagonist's inner con-flicts, he finally gains spiritual growth and obtains a higher level of moral maturity.展开更多
