自2019年12月31日湖北省武汉市卫健委首次通报当地新型冠状病毒肺炎病例以来,新冠病患一度遍布中国各个省份及多个国家,病毒的传播速度超乎人们预期。全球疫情升级是灾难,是对人类健康和生命安全的一大考验,更是对人们心理的一次历练。基于此,各地高校应抓住这一契机,分析大学生所表现出的复杂心理活动和行为方式,提出积极的教育对策,引导提升大学生在突发公共事件下的心理健康水平。 相似文献

Since it was first recognized in bacteria and archaea as a mechanism for innate viral immunity in the early 2010 s,clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein(Cas) has rapidly been developed into a robust, multifunctional genome editing tool with many uses. Following the discovery of the initial CRISPR/Cas-based system, the technology has been advanced to facilitate a multitude of different functions. These include development as a base editor, prime editor, epigenetic editor, and CRISPR interference(CRISPRi) and CRISPR activator(CRISPRa) gene regulators. It can also be used for chromatin and RNA targeting and imaging. Its applications have proved revolutionary across numerous biological fields, especially in biomedical and agricultural improvement. As a diagnostic tool, CRISPR has been developed to aid the detection and screening of both human and plant diseases, and has even been applied during the current coronavirus disease 2019(COVID-19) pandemic. CRISPR/Cas is also being trialed as a new form of gene therapy for treating various human diseases, including cancers, and has aided drug development. In terms of agricultural breeding, precise targeting of biological pathways via CRISPR/Cas has been key to regulating molecular biosynthesis and allowing modification of proteins, starch, oil, and other functional components for crop improvement. Adding to this, CRISPR/Cas has been shown capable of significantly enhancing both plant tolerance to environmental stresses and overall crop yield via the targeting of various agronomically important gene regulators. Looking to the future, increasing the efficiency and precision of CRISPR/Cas delivery systems and limiting off-target activity are two major challenges for wider application of the technology. This review provides an in-depth overview of current CRISPR development, including the advantages and disadvantages of the technology,recent applications, and future considerations. 相似文献

In response to the Covid-19 pandemic, medical educators have transformed pre-clerkship anatomy curricula into online formats. The purpose of this study was to evaluate the effectiveness and student perceptions of an online near-peer anatomy curriculum. The classes of 2022 and 2023 completed identical foundational anatomy curricula in-person, whereas the class of 2024 completed an adapted curriculum for remote online learning. Quantitative and qualitative responses were used to compare attitudes between instructional methods. Assessment scores and evaluation survey responses were collected from the classes of 2022 (n = 185), 2023 (n = 184), and 2024 (n = 183). Mean assessment scores (±SD) for the classes of 2022, 2023, and 2024 were 93.64% (±5.86), 93.75% (±4.09), and 92.04% (±4.83), respectively. Post hoc group comparisons showed the class of 2024 scored significantly lower than the two previous classes [2022: (H(1) = 18.58, P < 0.001), 2023: (H(1) = 18.65, P < 0.001)]. Mean survey results concerning curriculum quality were 4.06/5.00 for the class of 2023 and 3.57/5.0 for the class of 2024 (t(365) = 2.67, P = 0.008). Considering a small effect size (η2 = 0.034), there was no meaningful difference in student assessment scores. A potential drawback of online near-peer anatomy teaching remains in student perceptions of course quality; qualitative feedback suggested technological limitations and perceptions of online course instructors were partly responsible for lower student satisfaction. Following the Covid-19 pandemic, medical educators should incorporate the lessons learned from this unique educational inflection point to improve curricula moving forward. 相似文献

新冠肺炎疫情的持续蔓延为儿童青少年的发展带来了风险。积极心理学强调人类自身的潜能、美德、积极情绪等对个体发展的意义,通过使用预防性心理保健帮助个体适应环境,儿童青少年获得积极发展后,能对个人、家庭、社区及人类社会做出积极的贡献,并大大降低出现问题行为和罹患精神疾病的风险,与儿童青少年在常态化疫情防控下的发展需求相契合。本文通过对儿童青少年积极发展这一概念的探讨,提出为应对疫情常态化,应注重复原力和社会参与意识及行为的培养,并从个体、家庭、学校和社区等多个维度构建社会支持系统,开展心理健康教育,加强重点人群心理监测与干预,以促进儿童青少年的积极发展。 相似文献

It is said that a picture is worth a thousand words, but what about graphs? Although graphs have the potential to bring data to life, numerous studies show that learners struggle with graphical comprehension. Furthermore, many textbook examples on graphs are boring and appear meaningless to students. Students want to know more about something which is interesting, meaningful, and worth knowing, in other words, something relevant. With the outbreak of the novel coronavirus in December 2019, COVID‐19 is dominating the news worldwide, and the internet is flooded with visual presentations about the virus. To make statistics more fascinating and exciting, relevant and real‐world data such as these can be used in the classroom to stimulate the learning of important statistical concepts such as graphs. Curcio's three levels of graphical comprehension were used as a framework in this study, while the importance of developing a global view on distributions was also emphasized. 相似文献

This article explores the social determinants of adolescents’ access to education during the COVID-19 pandemic in three diverse urban contexts in Bangladesh, Ethiopia and Jordan. It provides novel empirical data from the Gender and Adolescence: Global Evidence longitudinal study, drawing on phone surveys (4441), qualitative interviews with adolescents aged 12–19 years (500), and key informant interviews conducted between April and October 2020. Findings highlight that the pandemic is compounding pre-existing vulnerabilities to educational disadvantage, and that gender, poverty and disability are intersecting to deepen social inequalities. The paper concludes by reflecting on policy implications for inclusive distance education in emergencies. 相似文献

Against the context of higher education expansion initiated in 1998, this Special Issue sets out to critically examine the major developmental trends in higher education in China. The present article sets out the broader policy context for the Special Issue with particular focus on reviewing the rapid expansion of higher education in the last two decades. More specifically, this article discusses the higher education development trends in China through the massification, diversification and internationalisation processes in transforming the higher education system. This article also highlights the major arguments of the articles being selected for this Issue. 相似文献
