认知视域下的大学生英语应用能力培养与立体化教学模式构建

认知语言学认为学习者的语言认知能力与语言学习的效果有着密切的关系。笔者在对英语专业学生和非英语专业学生的英语教学实践中发现,学生整体的英语综合应用能力差可以从认知方面找到其根源。因此,从认知的视角出发,探讨构建六位一体的立体化教学模式,对大学生英语应用能力培养意义重大。

Chinese Family Groups' Museum Visit Motivations: A Comparative Study of Beijing and Vancouver

This comparative study explored Chinese family groups' dominant visit motivations in science museums and aquariums in order to understand the perceptions of these audiences, who are an under‐represented cultural demographic in the literature. In this study, 503 Chinese participants—131 in the China Science and Technology Museum, Beijing; 127 in the Beijing Aquarium, Beijing; 136 in Science World British Columbia, Vancouver; and 109 in the Vancouver Aquarium, Vancouver—completed a Family Group Visit Motivation Questionnaire. The results report four dominant visit motivations for these Chinese family groups. Significant differences in a fifth motivation, social interaction, were detected in comparing the Beijing and Vancouver Chinese family samples. Also, Chinese family groups were more likely to perceive science museums to be settings that can satisfy their educational and personal interest needs, compared to aquariums. This study provides insights for science museums and aquarium practitioners to better understand this audience demographic.     

Bio-inspired untethered fully soft robots in liquid actuated by induced energy gradients

Soft robotics with new designs, fabrication technologies and control strategies inspired by nature have been totally changing our view on robotics. To fully exploit their potential in practical applications, untethered designs are preferred in implementation. However, hindered by the limited thermal/mechanical performance of soft materials, it has been always challenging for researchers to implement untethered solutions, which generally involve rigid forms of high energy-density power sources or high energy-density processes. A number of insects in nature, such as rove beetles, can gain a burst of kinetic energy from the induced surface-energy gradient on water to return to their familiar habitats, which is generally known as Marangoni propulsion. Inspired by such a behavior, we report the agile untethered mobility of a fully soft robot in liquid based on induced energy gradients and also develop corresponding fabrication and maneuvering strategies. The robot can reach a speed of 5.5 body lengths per second, which is 7-fold more than the best reported, 0.69 (body length per second), in the previous work on untethered soft robots in liquid by far. Further controlling the robots, we demonstrate a soft-robot swarm that can approach a target simultaneously to assure a hit with high accuracy. Without employing any high energy-density power sources or processes, our robot exhibits many attractive merits, such as quietness, no mechanical wear, no thermal fatigue, invisibility and ease of robot fabrication, which may potentially impact many fields in the future.     

合作素养:21世纪核心素养5C模型之五

A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2

The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus, and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed. On the other hand, several concerning SARS-CoV-2 variants, including Omicron, are required to be identified as soon as the samples are identified as ‘positive’. Unfortunately, a traditional PCR test does not allow their specific identification. Herein, for the first time, we have developed MOPCS (Methodologies of Photonic CRISPR Sensing), which combines an optical sensing technology-surface plasmon resonance (SPR) with the ‘gene scissors’ clustered regularly interspaced short palindromic repeat (CRISPR) technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants. MOPCS is a low-cost, CRISPR/Cas12a-system-empowered SPR gene-detecting platform that can analyze viral RNA, without the need for amplification, within 38 min from sample input to results output, and achieve a limit of detection of 15 fM. MOPCS achieves a highly sensitive analysis of SARS-CoV-2, and mutations appear in variants B.1.617.2 (Delta), B.1.1.529 (Omicron) and BA.1 (a subtype of Omicron). This platform was also used to analyze some recently collected patient samples from a local outbreak in China, identified by the Centers for Disease Control and Prevention. This innovative CRISPR-empowered SPR platform will further contribute to the fast, sensitive and accurate detection of target nucleic acid sequences with single-base mutations.
