Identifying emotional causes of mental disorders from social media for effective intervention

Identifying the emotional causes of mental illnesses is key to effective intervention. Existing emotion-cause analysis approaches can effectively detect simple emotion-cause expressions where only one cause and one emotion exist. However, emotions may often result from multiple causes, implicitly or explicitly, with complex interactions among these causes. Moreover, the same causes may result in multiple emotions. How to model the complex interactions between multiple emotion spans and cause spans remains under-explored. To tackle this problem, a contrastive learning-based framework is presented to detect the complex emotion-cause pairs with the introduction of negative samples and positive samples. Additionally, we developed a large-scale emotion-cause dataset with complex emotion-cause instances based on subreddits associated with mental health. Our proposed approach was compared to prevailing CNN-based, LSTM-based, Transformer-based and GNN-based methods. Extensive experiments have been conducted and the quantifiable outcomes indicate that our proposed solution achieves competitive performance on simple emotion-cause pairs and significantly outperformed baseline methods in extracting complex emotion-cause pairs. Empirical studies further demonstrated that our proposed approach can be used to reveal the emotional causes of mental disorders for effective intervention.

虚拟社区中知识交流的特点分析——基于CSDN技术论坛的实证研究

以国内著名的技术网络论坛CSDN为研究实例,从中抽取出知识交流网络,采用复杂网络的分析方法进行分析,试图定量化地揭示虚拟社区中知识交流的特点。论文一方面分析知识交流网络的基本统计量,指出它具备无标度性质和小世界效应,并对其成因进行分析;另一方面通过分析知识交流网络中的“用户三角形”,揭示了虚拟社区中知识传播的两种基本图式。     

复杂网络统计参量对病毒传播速率的影响

复杂网络统计参量是描述复杂网络结构的普适参量,病毒的传播与这些基本参量密切相关,病毒传播速率与复杂网络统计参量间存在确定的联系。文章推论了复杂网络中病毒传播速率与基本网络参量的函数关系。利用这一函数可以在已知的网络结构参数时,得到病毒传播的预测值。     

论法律对权力领域渗透的形态

正确处理权力与法律的关系是建设社会主义法治国家的核心问题和衡量法治建设成效的重要标准。法律对权力领域的渗透和影响的重点在于经过漫长的历史渐进过程形成由较弱势力向较强势力发挥作用的机制,法律对权力领域渗透的形态根据渗透的范围和程度可以划分为未渗透形态、部分渗透形态和完全渗透形态。     

从爱欲的反动到救赎的探寻——浅析约翰·厄普代克小说中的“欲望”情结

美国当代著名作家约翰·厄普代克认为爱欲是一种原始生命力,并把这种生命力寓于艺术中让其成为创作的动力与命脉。本文从厄普代克小说中主题入手,揭示了其潜在的欲望情结,并借此开始了对生命的扣问。

Effects of agonist–antagonist complex resistance training on upper body strength and power development

Abstract

The objective of this study was to examine the chronic effects on strength and power of performing complex versus traditional set training over eight weeks. Fifteen trained males were assessed for throw height, peak velocity, and peak power in the bench press throw and one-repetition maximum (1-RM) in the bench press and bench pull exercises, before and after the eight-week programme. The traditional set group performed the pulling before the pushing exercise sets, whereas the complex set group alternated pulling and pushing sets. The complex set training sessions were completed in approximately half the time. Electromyographic (EMG) activity was monitored during both test sessions in an attempt to determine if it was affected as a result of the training programme. Although there were no differences in the dependent variables between the two conditions, bench pull and bench press 1-RM increased significantly under the complex set condition and peak power increased significantly under the traditional set condition. Effect size statistics suggested that the complex set was more time-efficient than the traditional set condition with respect to development of 1-RM bench pull and bench press, peak velocity and peak power. The EMG activity was not affected. Complex set training would appear to be an effective method of exercise with respect to efficiency and strength development.
