The Interaction between Parents and Children:three Essays on Family Economics
No full textParent-child interactions play a key role in family wellbeing and have long-term effects on inequalities. Therefore, it is critical to analyze parent-child interactions over the life cycle. In this thesis, we examine the impact of parent-child interactions in China and the Netherlands, two countries that differ significantly in terms of their cultures and social welfare systems. Chapter 2 examines the effect of daycare use at age 0-2 on children’s cognitive abilities and self-assessed qualities at age 8 in the Netherlands. In Chapter 3, we examine the effect of parental housing wealth on children’s marriage prospects, focusing on the context of China. In Chapter 4, we investigate the effect of losing a child in China on parents’ physical health, mental health, and wellbeing later in life

A study of the modern Chinese novel, Gao Yubao and its author Gao Yubao
No full textGao Yubao, a soldier in the Chinese People's Liberation Army, was nearly illiterate when he began to write his autobiographical novel, Gao Yubao, in 1949. The PLA's literary branch helped him finish the novel and after its publication Gao and his struggle to become literate by writing a novel served as an inspiration for others striving for education. Gao Yubao was republished several times up until as late as the 1970's and each time it was republished it was revised. This paper traces the history of the novel Gao Yubao and its author with special attention being given to comparing the changes made in the various editions of the novel. The conflicts between amateurism and professionalism and between fact and romanticization and those conflicts inherent in the constant revisings demanded of an already revised work are shown to be unresolvable because of the nature of contemporary Chinese literature.Arts, Faculty ofAsian Studies, Department ofGraduat
The effect of parental health shocks on living arrangements and employment
No full textThis study investigates the impacts of health shocks among older individuals on the dynamics of their living arrangements in Europe and the United States. Exploiting unpredicted health shocks, we use an event-study difference-in-differences approach to demonstrate that health shocks increase difficulties with activities of daily living and instrumental activities of daily living, thereby increasing the need for care. Our findings indicate that health shocks raise the probability of nursing home residency and co-residence with adult children by 0.7 and 1.4 percentage points in Europe, and by 2.1 and 1.8 percentage points in the U.S., respectively. Further analyses reveal that more generous long-term care public policies correlate with a higher probability of nursing home residency and a lower probability of co-residing with adult children, highlighting the significant role of public policies in household responses to health shocks. Additionally, we find that health shocks negatively impact adult children's labor supply, particularly in the U.
Accommodating Nomocharis in Lilium (Liliaceae)
No full textControversy regarding the status of the genus Nomocharis Franchet (1889: 113) has been undergoing since its recognition by Franchet (1889). Recent molecular studies (Nishikawa et al. 1999, Hayashi & Kawano 2000, Nishikawa et al. 2001, Ronsted et al. 2005, Peruzzi et al. 2009) have resolved Nomocharis as being nested within Lilium Linaeus (1753: 302). Results of our own previous studies (Gao et al. 2012, Gao et al. 2013a, Gao et al. 2013b), with expanded sampling of species of Nomocharis have been congruent with those of previous studies by others. Thus recognition of Nomocharis would render Lilium paraphyletic. We prefer to recognize a monophyletic Lilium here, although paraphyletic groups are sometimes advocated in literature (e.g., Brummitt, 2014; Ehrendorfer & Barfuss, 2014; George, 2014; Horandl, 2014; Stuessy & Horandl, 2014; Stuessy et al., 2014). Most recently, we proposed that the morphological divergence between Nomocharis and Lilium was the result of habitat specialization (Gao et al. 2015). The extensive introgression caused by hybridization within Lilium and Nomocharis (Gao et al. 2013a, 2015) supports a single-genus concept

Adversarial Attacks against the Perception System of Autonomous Vehicles
No full textThe rapid advancement in autonomous driving technology underscores the importance of studying the fragility of perception systems in autonomous vehicles, particularly due to their profound impact on public transportation safety. These systems are of paramount importance due to their direct impact on the lives of passengers and pedestrians. Additionally, their reliability can be easily compromised given the complexity and unpredictability of driving environments. However, current research and existing regulations often fail to adequately address the adversarial robustness of autonomous vehicle perception systems. This thesis delves into the adversarial robustness of camera-based perception systems of autonomous vehicles. Our research concentrates on developing and implementing evasion attacks that use black-box gradient estimation, as well as physical attacks in traffic sign detection and classification systems. Our findings indicate that even minor perturbations can impact the accuracy of these systems, leading to detection and classification errors. This finding highlights a critical vulnerability in the perception system's robustness against adversarial attacks. Moreover, the study extends to assess the transferability of adversarial examples across diverse perception models. Our results also expose significant gaps in the current regulatory frameworks of autonomous vehicles, necessitating the establishment of more rigorous and comprehensive safety standards.https://github.com/yuxing-gao/adversarial-attack-traffic-sign-detectionMechanical Engineering | Systems and Contro
