    Abstract The Corona Virus Disease 2019 epidemic broke out in 2020, and digital technologies pervaded all aspects of people’s lives, resulting in a significant shift in how education is delivered. The importance and role of digital technologies and online learning are highlighted in this paper, which examines the challenges posed by the sudden epidemic crisis to higher education institutions, analyses the factors that universities must consider in order to effectively create flexible learning pathways, and examines the challenges posed by the sudden epidemic crisis to higher education institutions. In the postepidemic era, the use of the Internet and online teaching platforms by university faculty to integrate online and offline teaching has not only facilitated the construction of “golden courses” but also added impetus to teaching reform, and digital technology-based teaching models have provided higher education practitioners with the opportunity to rethink scholarship and innovative teaching. In this paper, we propose a personalized learning resource recommendation system that includes user profiles to fully explore and analyze users’ learning behaviors and cognitive characteristics and enhance the depth and breadth of personalized education with the help of the Internet and artificial intelligence technologies in order to provide meaningful information and thoughts for higher education institutions to discuss and adapt to the education model in the postepidemic era. The goal is to provide useful information and ideas for higher education institutions to discuss and adapt to the postepidemic education paradigm.

    Abstract [Objective] Conservation tillage is an important way to promote the sustainable and intensive utilization of cultivated land, cope with the impact of climate change, and promote the transformation of grain production mode. Accurately evaluating the impact of conservation tillage technology adoption on grain production not only can provide empirical evidence for increasing the scale and quality of conservation tillage, but also has important practical significance for ensuring food security. [Methods] Based on the survey data of grain growers from 14 provinces in China, the effect of conservation tillage technology adoption on yield increasing and stabilizing, and its heterogeneity in different regions and under different cropping systems and technology combinations were investigated under the counterfactual framework by using the endogenous switching regression (ESR) model. [Results] (1) Adopting conservation tillage technologies reduces the risk of grain yield reduction while increasing the mean of yield, which shows obvious yield-increasing effect and yield-stabilizing effect. Under the counterfactual assumption, if the farmers who adopt conservation tillage technologies did not do so, their grain mean yield would have reduced by 3.4%, and their risk of yield reduction would have increased by 17.5%. (2) The effect of conservation tillage technology adoption on yield increasing and stabilizing are heterogeneous. The adoption of conservation tillage technologies can enhance the grain mean yield of farmers in the eastern region of China more strongly than that in the central and western regions, and can only reduce the risk of grain yield reduction of farmers in the eastern region. Compared with areas with double cropping and above, the adoption of conservation tillage technologies by farmers in areas with one cropping failed to increase grain yield, but increased the risk of grain yield reduction. (3) Conservation tillage technologies have integrated adoption effect, and the yield-increasing effect and ...

    Abstract Unraveling the neurobiological foundations of childhood maltreatment is important due to the persistent associations with adverse mental health outcomes. However, the mechanisms through which abuse and neglect disturb resting-state network connectivity remain elusive. Moreover, it remains unclear if positive parenting can mitigate the negative impact of childhood maltreatment on network connectivity. We analyzed a cohort of 194 adolescents and young adults (aged 14-25, 47.42% female) from the Neuroscience in Psychiatry Network (NSPN) to investigate the impact of childhood abuse and neglect on resting-state network connectivity. Specifically, we examined the SAN, DMN, FPN, DAN, and VAN over time. We also explored the moderating role of positive parenting. The results showed that childhood abuse was linked to stronger connectivity within the SAN and VAN, as well as between the DMN-DAN, DMN-VAN, DMN-SAN, SAN-DAN, FPN-DAN, SAN-VAN, and VAN-DAN networks about 18 months later. Positive parenting during childhood buffered the negative impact of childhood abuse on network connectivity. To our knowledge, this is the first study to demonstrate the protective effect of positive parenting on network connectivity following childhood abuse. These findings not only highlight the importance of positive parenting but also lead to a better understanding of the neurobiology and resilience mechanisms of childhood maltreatment.
