Emotional AI and EdTech: serving the public good?

ABSTRACT

Education Technology (EdTech) companies are deploying emotional AI to quantify social and emotional learning. Focusing on facial coding emotional AI that uses computer vision and algorithms to see, recognise, categorise and learn about facial expressions of emotion, this paper evaluates nascent usage of these technologies in education. To do this, it assesses the nature of child rights, the history and modern usage of face-based emotional AI, methodology and efficacy, and what this paper sees as a clash of private and public interests. Concern is shown to be two-fold: first is on method, especially given scope for material effects on students; second are ethical and legal concerns. While proposing a list of considerations for any implementation for these technologies in the classroom, the paper concludes that significant risks exist in deployment of these technologies in the classroom.

For whom the bell tolls: The firm-level effects of automation on wage and gender inequality

This paper investigates the impact of investment in automation- and AI-related goods on within-firm wage inequality in the French economy during the 2002–2017 period. We document that most wage inequality in France is accounted for by differences among workers belonging to the same firm rather than by differences between sectors, firms, and occupations. Using an event-study approach on a sample of firms importing automation- and AI-related goods, we find that spike events related to the adoption of automation- and AI-related capital goods are not followed by an increase in within-firm wage inequality or in gender wage inequality. Instead, wages increase by 1% three years after the events at different percentiles of the distribution. Our findings are not linked to the rent-sharing behavior of firms obtaining productivity gains from automation and AI adoption. Instead, if wage gains do not differ across workers along the wage distribution, worker heterogeneity will still be present. Indeed, in agreement with the framework in Abowd et al. (1999b), most of the overall wage increase is due to the hiring of new employees. This adds to previous findings presenting a picture of a ‘labor friendly’ effect of the latest wave of new technologies within adopting firms.     

基于SES差异下用户AI学习平台持续使用意愿影响机理研究

【目的/意义】在积极推动AI教育发展的背景下,探寻何种因素致使用户持续使用AI学习平台是一个关键 问题。【方法/过程】本研究将家庭社会经济地位SES（social economic status）不平等作为研究情景,构建基于计划行为 理论的中学生AI学习平台持续使用意愿影响因素研究模型。通过对SES进行聚类分组,并对比优劣势两组在进行 模型检测时的路径系数差异显著性以研究SES差异对持续使用意愿相关因素的影响。【结果/结论】主观规范和感知 行为控制是用户持续使用意愿的直接影响因素,学习功利性、学习享乐性、自我效能感、感知易用性、可获取性间接 影响持续使用意愿,其中态度影响不显著。SES 对自我效能感与感知行为控制的正向关系有调节作用。【创新/局 限】本研究引入用户内在动机和人工智能学习平台内部因素对计划行为理论进行拓展。在不同教育程度群体的研 究层面上还有待进一步剖析。

SCADA data based condition monitoring of wind turbines

Wind turbines（WTs） are quite expensive pieces of equipment in power industry. Maintenance and repair is a critical activity which also consumes lots of time and effort, hence making it a costly affair. Carefully planning the maintenance based upon condition of the equipment would make the process reasonable. Mostly the WTs are equipped with some kind of condition monitoring device/system, which provides the information about the device to the central data base i.e., supervisory control and data acquisition（SCADA） data base. These devices/systems make use of data processing techniques/methods in order to detect and predict faults. The information provided by condition monitoring equipments keeps on recoding in the SCADA data base. This paper dwells upon the techniques/methods/algorithms developed, to carry out diagnosis and prognosis of the faults, based upon SCADA data.Subsequently data driven approaching for SCADA data interpretation has been reviewed and an artificial intelligence（AI） based framework for fault diagnosis and prognosis of WTs using SCADA data is proposed.     

残忍的才华——五篇小说的比较分析

现代作家中不乏写残忍故事的高手,他们各具特色。艾芜《山峡中》用温情融化残忍,刘庆邦《逃荒》用温情为残忍辩护,张爱玲《金锁记》讲述了温情转化为残忍的过程,余华《现实一种》展示了暴力的极端形式,鲁迅《药》却重在思想层面的深刻。
