Flood Detection Based on Unmanned Aerial Vehicle System and Deep Learning.Kaixin Yang,SujieZhang,Xinran Yang &Nan Wu -2022 -Complexity 2022:1-9.detailsFloods are one of the main natural disasters, which cause huge damage to property, infrastructure, and economic losses every year. There is a need to develop an approach that could instantly detect flooded extent. Satellite remote sensing has been useful in emergency responses; however, with significant weakness due to long revisit period and unavailability during rainy/cloudy weather conditions. In recent years, unmanned aerial vehicle systems have been widely used, especially in the fields of disaster monitoring and complex environments. This study (...) employs deep learning models to develop an automated detection of flooded buildings with UAV aerial images. The method was explored in a case study for the Kangshan levee of Poyang Lake. Experimental results show that the inundation for the focal buildings and vegetation can be detected from the images with 88% and 85% accuracy, respectively. And further, we can estimate the buildings’ inundation area according to the UAV images and flight parameters. The result of this study shows promising value of the accuracy and timely visualization of the spatial distribution of inundation at the object level for the end users from flood emergency response sector.

The Impact of Leader Proactivity on Follower Proactivity: A Chain Mediation Model.KaixinZhang &Zilong Cui -2022 -Frontiers in Psychology 13.detailsThis study aims to explore the linking mechanisms underlying the relationship between leader proactivity and follower proactivity. Drawing on social learning theory, the present research investigates the effects of leader proactivity on follower proactivity by developing a chain mediation model. An analysis of three-wave lagged data on 575 employees of six firms in China shows that leader proactivity is positively related to follower proactivity and that employees’ role breadth self-efficacy and felt responsibility for constructive change mediate this relationship. The analytical (...) results also show that leader proactivity facilitates follower value congruence, which in turn enhances followers’ RBSE and FRCC and ultimately promotes followers’ proactivity. The results extend the current proactivity literature and fill the research gap by investigating the relationship between leader proactivity and follower proactivity. The current study also contributes to the literature by identifying the mediating mechanism of the “can do” and “reason to” mechanisms that link leader proactivity to follower proactivity. (shrink)
Accounting for similarity-based reasoning within a cognitive architecture.Ron Sun &XiZhang -unknowndetailsThis work explores the importance of similarity-based processes in human everyday reasoning, beyond purely rule-based processes prevalent in AI and cognitive science. A unified framework encompassing both rulebased and similarity-based reasoning may provide explanations for a variety of human reasoning data.

Childhood Experiences and Psychological Distress: Can Benevolent Childhood Experiences Counteract the Negative Effects of Adverse Childhood Experiences?Hao Hou,CaochenZhang,Jie Tang,Jingjing Wang,Jiaqi Xu,Qin Zhou,Wenjun Yan,Xiuyin Gao &Wei Wang -2022 -Frontiers in Psychology 13.detailsBackgroundChildhood experiences can exert a huge impact on adult psychological conditions. Previous studies have confirmed the effects of adverse childhood experiences and benevolent childhood experiences on psychological distress separately, but few studies explored a combined effect of ACEs and BCEs on psychological distress. The aim of this study was to explore a combined effect of ACEs and BCEs on psychological distress among Chinese undergraduates.MethodsParticipants were undergraduates aged 17–24 years and completed a self-reported questionnaire. A series of regression analyses were conducted (...) to examine the association between childhood experiences and psychological distress.ResultsA total of 65.7% of undergraduates had BCEs, 27.1% of undergraduates had ACEs, and 12.9% of undergraduates had ACEs and BCEs simultaneously. Logistic regression analysis indicated that undergraduates who experienced high ACEs were more likely to have a high risk of psychological distress [odds ratio = 1.46, 1.84, and 3.15 for uncertainty stress, depressive symptoms, and suicidal ideation, respectively], while undergraduates who experienced High BCEs were less likely to have psychological distress compared with Low-Both group. The combined effect of ACEs and BCEs could also play as a protective factor in uncertainty stress and depressive symptoms.ConclusionOur findings suggested that ACEs and BCEs could not only predict the psychological distress independently, but also BCEs could counteract the negative effect of ACEs in psychological problems. There is an even greater need to identify and support the victims of ACEs and to increase BCEs in early childhood. (shrink)
On the hermeneutics of screen time.Jesper Aagaard,Emma Steninge &YibinZhang -2023 -AI and Society 38 (6):2329-2337.detailsScreen time has become a hot button issue in psychology with researchers fiercely debating its mental effects. If we want to understand the psychological dynamics of technology use, however, a numerical conceptualization of screen time will lead us to gloss over crucial distinctions. To make this point, the present article takes a hermeneutic approach to a negative form of screen time known as ‘phubbing’, which is the practice of snubbing conversational partners in favor of one’s phone. Using interview data, it (...) is demonstrated that whether or not phone use amounts to phubbing, that is, whether or not it tips over and becomes harmful, depends on a host of contextual factors such as relation (who), content (what), purpose (why), timing (when), and communication (how). These findings demonstrate that not all screen time is created equal: what is harmful and inappropriate in one context is benign in another, and vice versa. Simply put, screen time is not a numerical entity whose causal effects we can measure and explain, but a meaningful activity that we must try to understand. (shrink)

An emerging role of transcription in chromosome segregation: Ongoing centromeric transcription maintains centromeric cohesion.Yujue Chen,QianZhang &Hong Liu -2022 -Bioessays 44 (1):2100201.detailsNon‐coding centromeres, which dictate kinetochore formation for proper chromosome segregation, are extremely divergent in DNA sequences across species but are under active transcription carried out by RNA polymerase (RNAP) II. The RNAP II‐mediated centromeric transcription has been shown to facilitate the deposition of the centromere protein A (CENP‐A) to centromeres, establishing a conserved and critical role of centromeric transcription in centromere maintenance. Our recent work revealed another role of centromeric transcription in chromosome segregation: maintaining centromeric cohesion during mitosis. Interestingly, this (...) role appears to be fulfilled through ongoing centromeric transcription rather than centromeric transcripts. In addition, we found that centromeric transcription may not require some of the traditional transcription initiation factors, suggestive of “uniqueness” in its regulation. In this review, we discuss the novel role and regulation of centromeric transcription as well as the potential underlying mechanisms. (shrink)

John Dewey, Liang Shuming, and China's Education Reform: Cultivating Individuality.HuajunZhang -2013 - Lexington Books.detailsThis book addresses an often-ignored theme in the mission of the current Chinese education reform: cultivating students’ individuality as a foundation of learning. Moreover, it tries to revive the Confucian tradition of self-cultivation while building a connection with the western idea of individuality to provide a meaningful resource for the current reform of Chinese education.
