《已故上校的女儿们》中的象征意象分析

《已故上校的女儿们》是著名短篇小说家凯瑟琳·曼斯菲尔德的经典之作。这篇小说独特的叙事结构、淡化的故事情节和巧妙转换的叙述角度为人们所津津乐道,与此同时,曼斯菲尔德对象征意象的娴熟运用也让这篇小说意味深长、回味无穷。作品中象征性意象分为三类,分别象征着父权主义、维多利亚时代妇女的希望和她们的实际地位。通过对这些意象的分析,读者可以更深刻地理解该小说及曼斯菲尔德的写作风格。     

论志愿服务在大学生道德养成中的作用

论述了志愿服务对大学生道德品质的形成与发展的意义,阐释了志愿服务具有的志愿性、公益性、非营利性等伦理特征。大学生参加志愿服务活动,可以提高道德认识水平,丰富道德情感,强化道德责任,发展道德智慧,提升道德实践能力。当前,我国大学生志愿服务活动应更好地理解志愿服务的内涵,理解青少年道德品质形成发展的规律,坚持量力性原则,注意利他性动机与利己性动机的结合,因势利导,以促进大学生志愿服务活动向积极的方向发展。

情绪智力研究对我国高校人才培养的启示

有心理学家称情绪智力(emotional intelligence)是决定个体成功与否的决定因素,因而情绪智力越来越受到人们的重视,其研究成果逐渐辐射到包括高校人才培养在内的社会各个领域。情绪智力理论打破了认知智力一统教育天下的局面,迫使高校教育作出适当的调整,对高校人才培养有着重要的启示和意义。本文通过对情绪智力研究的相关成果的分析,探讨了对高校人才培养产生的启示,并试图构建新的人才培养模式。     

Replication,pathogenicity, and transmission of SARS-CoV-2 in minks

Minks are raised in many countries and have transmitted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans. However, the biologic properties of SARS-CoV-2 in minks are largely unknown. Here, we investigated and found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts, and transmits efficiently in minks via respiratory droplets; pulmonary lesions caused by SARS-CoV-2 in minks are similar to those seen in humans with COVID-19. We further found that a spike protein-based subunit vaccine largely prevented SARS-CoV-2 replication and lung damage caused by SARS-CoV-2 infection in minks. Our study indicates that minks are a useful animal model for evaluating the efficacy of drugs or vaccines against COVID-19 and that vaccination is a potential strategy to prevent minks from transmitting SARS-CoV-2.     

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.
