Witness Testifying System in Court under the View of Online Litigation Mode
- Authors:
- Keywords: online litigation; A witness testifies; Appear in court
- Abstract: In litigation, whether the parties can obtain the expected result is often reflected in their use of evidence. As a single type of evidence, witness testimony can often play a better proof effect once it is recognized as true. At present, there exist phenomena such as the low rate of witness appearing in court and the difficulty of testifying in court, which can lead to unnecessary delay of the proceedings and make the truth difficult to be discovered. In the phase of COVID-19 prevention and control, regional courts have tried to shift from offline to online litigation, which also facilitates witnesses to testify in court. And the judge, with the aid of artificial intelligence, will also be helpful to judge the credibility of the witness testimony to a certain extent. Online litigation can solve some of the effects of witness testifying in court, or it will be a good opportunity to reverse our witnesses testifying in court.

Analysis on the Application of Organic Polymer Flocculants in Sludge Dewatering
- Authors:
- Keywords: Organic Polymer; Flocculant; Sludge Dewatering; Inorganic Flocculant
- Abstract: With the rapid development of China's economy, the components of sewage discharged from industrial manufacturing and daily life have gradually become diversified, resulting in a large amount of sludge generated during the sewage treatment process. Sludge contains a large amount of phosphorus, nitrogen, potassium and metal elements. For sludge dewatering, organic polymer flocculants have demonstrated more outstanding dewatering performance compared with previous inorganic flocculants. Therefore, this paper mainly analyzes and studies the application of organic polymer flocculants in sludge dewatering, objectively expounds the application effects of different types of organic polymer flocculants in sludge dewatering in recent years, and how to select organic polymer flocculants. By summarizing their treatment methods, it can be concluded that the addition of cationic inorganic flocculants and the proportioning of organic polymer flocculants with a relatively high molecular content have more outstanding performance in the actual application of sludge dewatering.

Research on the Preparation of Modified Polyacrylic Acid Superabsorbent Resin and Its Potential Application in Fruit Preservation in Combination with Chinese Herbal Medicine Composites
- Authors:
- Keywords: Superabsorbent Resin; Salt Resistance; Biodegradation; Fruit Preservation
- Abstract: In order to enhance the water absorption capacity and degradation performance of acrylic acid superabsorbent resin (PAA), this paper used 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and naturally degradable macromolecular carboxymethyl cellulose (CMC) as modifiers and adopted the aqueous solution polymerization method to prepare modified polyacrylic acid (PAA) superabsorbent resin. The results showed that when the content of acrylic acid was 21%, and the contents of AMPS, CMC, cross-linking agent and initiator were 20%, 1.8%, 0.02% and 2% of the mass of AA respectively, the water absorption capacity of the prepared PAA superabsorbent resin in deionized water increased from 483 g/g before modification to 875 g/g, and the water absorption capacity in physiological saline was 238 g/g. The degradation rate of the modified PAA in cellulase was 64.8%. It can be seen that the modification with CMC and AMPS can improve the water absorption, salt resistance and degradation performance of PAA resin. Meanwhile, the composite material of modified PAA superabsorbent resin and Chinese herbal medicine powder can prolong the shelf life of fruits and vegetables. The research results can provide a reference for the further research of fruit preservatives and a new idea for the expanded application of superabsorbent resins.

对外汉语教师运用情境学习法的教学成效分析──以舞蹈戏剧融入成语教学为例
An Analysis of the Effectiveness of Chinese Idiom Stories in Situational Learning for Chinese Language Teachers as a Foreign Language —Taking Drama and Dance Activities as an Example of Integrating Idiom Teaching
- Authors:
- Keywords: Idiom stories; Teaching Chinese as a foreign language; Drama and dance; Situational learning成语故事; 对外汉语教师; 戏剧舞蹈; 情境学习
- Abstract: Language is the umbilical cord of culture, and learning Chinese idioms for overseas Chinese children is a journey to ffnd their roots. Idioms appear more and more frequently in the text as the grade level increases. Idioms are good materials for Chinese language teaching and have a certain impact on essay score evaluation. TTis study attempts to integrate drama and dance activities into idiom teaching, aiming to change the stereotype of overseas Chinese students who have difffculty understanding Chinese characters, increase their interest in learning, and enhance their humanistic literacy. TTe teaching team of Chinese as a foreign language led by the author has gone through 12 trials, conducting in-depth interviews and questionnaire surveys with overseas elderly Chinese to explore how to quickly and effectively learn Chinese while ensuring that every new generation of overseas Chinese does not forget their roots. TTis research team found that four teaching modes can improve the Chinese listening, speaking, reading, and writing abilities of overseas Chinese students in a short period of time. Among them, using some concise and easy to understand idiom stories is an effective way to get started.语言是文化的脐带，海外华侨子弟学习中国成语是一趟寻根旅程。成语在课文中出现的数量随着年级提升而逐渐增加，成语作为语文教学良好材料，在作文评分中具有一定影响。本研究尝试将戏剧舞蹈活动融入成语教学，期望旨在改变海外华侨学生对中国文字晦涩难懂的刻板印象，增加学生学习兴趣并提升他们的人文素养。笔者带领的对外汉语教学团队历经12届试验，通过对海外年长华人进行深度访谈和问卷调查，探讨如何高效快速地学会汉语，同时确保每位海外新生代华人子弟不忘祖国文化。研究团队发现，采用四种教学模式能够在短时间内提升海外华侨学生的听说读写能力，尤其是运用简明易懂的成语故事，是一种有效的教学方法。

法医精神病学和刑事司法中的神经预测和人工智能：神经法视角
Neuroprediction and A.I. in Forensic Psychiatry and Criminal Justice: A Neurolaw Perspective
- Authors:
- Keywords: Neuroprediction; Artificiaintelligence; Recidivism; Forensicpsychiatry; Riskassessment; Neurolaw神经预测; 人工智能; 累犯; 法医精神病学; 风险评估; 神经法
- Abstract: Advances in the use of neuroimaging in combination with A.I., and specifically the use of machine learning techniques, have led to the development of brain-reading technologies which, in the nearby future, could have many applications, such as lie detection, neuromarketing or brain-computer interfaces. Some of these could, in principle, also be used in forensic psychiatry. The application of these methods in forensic psychiatry could, for instance, be helpful to increase the accuracy of risk assessment and to identify possible interventions. This technique could be referred to as “A.I. neuroprediction” and involves identifying potential neurocognitive markers for the prediction of recidivism. However, the future implications of this technique and the role of neuroscience and A.I. in violence risk assessment remain to be established. In this paper, we review and analyze the literature concerning the use of brain-reading A.I. for neuroprediction of violence and rearrest to identify possibilities and challenges in the future use of these techniques in the fields of forensic psychiatry and criminal justice, considering legal implications and ethical issues. The analysis suggests that additional research is required on A.I. neuroprediction techniques, and there is still a great need to understand how they can be implemented in risk assessment in the field of forensic psychiatry. Besides the alluring potential of A.I. neuroprediction, we argue that its use in criminal justice and forensic psychiatry should be subjected to thorough harms/benefits analyses not only when these technologies will be fully available, but also while they are being researched and developed.神经影像学与人工智能结合使用的进步，特别是机器学习技术的使用，促进了大脑阅读技术的发展。这些技术在不久的将来可能被广泛应用，例如测谎、神经营销或大脑计算机接口。其中一些原则上也可用于法医精神病学。这些方法在法医精神病学中的应用可能有助于提高风险评估的准确性并确定可能的干预措施。这种技术可以称为“人工智能神经预测”，它涉及识别潜在的神经认知标志物来预测累犯。然而，这项技术的未来意义以及神经科学和人工智能在暴力风险评估中的作用仍有待确定。本文回顾和分析了有关使用大脑阅读人工智能对暴力和再逮捕进行神经预测的文献，以确定未来在法医精神病学和刑事司法领域使用这些技术的可能性和挑战，同时考虑了法律影响和伦理问题。分析表明，需要对人工智能神经预测技术进行更多研究，并且非常有必要了解如何在法医精神病学领域的风险评估中实施这些技术。除了人工智能神经预测的诱人潜力之外，本文认为，在这些技术完全可用时以及在其研究和开发过程中都应该对其在刑事司法和法医精神病学中的使用进行彻底的危害或者益处分析。
