Decentralized propaganda in the era of digital media: The massive presence of the Chinese state on Douyin

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract The rise of social media in the digital era poses unprecedented challenges to authoritarian regimes that aim to influence public attitudes and behaviors. To address these challenges, we argue that authoritarian regimes have adopted a decentralized approach to produce and disseminate propaganda on social media.

No added cost: Emotion recognition in co‐occurring ADHD and ASD

open access: yesBritish Journal of Clinical Psychology, EarlyView.
Abstract Objectives Facial emotion recognition (FER) is fundamental for social interaction, yet this ability is often impaired in attention‐deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD). While research has documented these difficulties, two key questions remain: Are these deficits specific to recognising emotions or do they ...

风云四号闪电成像仪聚类算法的参数化方案

open access: yesDianci bileiqi, 2019
风云四号静止卫星(FY-4)上携带的闪电成像仪(LMI,lightning mapping imager)可以很好地实时监测对流层的闪电活动情况,但由于目前公开的1 min事件产品(event)并不对应于一次次的闪电(flash),因此需要进行"聚类",也就是将事件产品(event)转化为闪电(flash)数据。为了得到适合LMI的闪电聚类算法,本文选取了LMI空间像元分辨率不同的两个典型区域,一个是像元分辨率约为8 km的西南地区(东经,北纬),另一个是像元分辨率约为12 km的东北地区(东经,北纬),

Need for expanded environmental measurement capabilities in geosynchronous Earth orbit [PDF]

open access: yes
The proliferation of environmental satellites in low altitude earth orbit (LEO) has demonstrated the usefulness of earth remote sensing from space. As use of the technology grows, the limitations of LEO missions become more apparent.

Task‐specific associations between holistic processing and individual differences in face memory

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Whether individual differences in face identification can be predicted by holistic processing, and whether both share a common underlying mechanism, remain open questions. Past studies exploring this association have produced mixed findings, but they have typically examined only a subset of holistic processing measures, focused largely on ...
