英汉文化差异与语言学习

不同社会 ,不同历史背景产生了不同的文化和语言 ,这些文化又会自然地反映在语言中 ,我们学习一门语言 ,不能只是掌握其基本技能 ,还应注意到语言和文化的关系 ,只有充分地了解了这种文化差异 ,我们才能真正掌握好这门语言。     

组织学习：管理学视角下的多元理论

就管理学领域中关于组织学习的理论进行了比较系统的研究.在彼得·帕沃夫斯基提出的五大类组织学习理论的分类基础上,进一步对每类理论下各种研究视角和研究思路进行了更为系统的规范分析.主要是对管理学中关于组织学习问题研究的各种理论的缘起、分化、进程及现状进行了系统的分析与评价.研究发现,由于学者们对组织学习的本质的看法、研究视角以及研究范式的不同,使得组织学习问题的研究呈现出理论多元化倾向.但近年来,一些从不同角度研究组织学习问题的理论,又正在趋向于新的整合.认为,关于组织学习问题的更为系统的看法,将建立在关于组织学习本质的多元视角而形成的综合观点基础之上.     

Impact of image super-resolution technology on comparison of personal image

Objective Through coalescence into deep learning, image super-resolution technology is being paid of attention for forensic personal imaging. Thus, a trial was here to carry out about the impact of image super-resolution technology on comparison of personal photographs from cases or events. Methods With 94 sets of sampling personal photographs collected from real cases, grouping was made on their respective quality-different image so that two image super-resolution algorithms were adopted to enhance the image of personal photograph. Such resultant image was compared against its original photograph image at 1 ∶ 1 (or N) contraposition under different preset conditions, hence having brought forth the intrinsic alternation of causation. Results Comparison results showed that the image super-resolution technology is not universal for improvement of image, demonstrating that it is not so good to improve the low and medium quality images as the sharpening processing, leaving the high quality image being improved significantly yet less practical applicability. Nevertheless, the image super-resolution technology is able to render a good improvement into an individual image. Conclusions From this analysis, the image super-resolution technology is referential for forensic personal image to utilize practically, yet not be over-relied on. © 2021, Editorial Office of Forensic Science and Technology.

基于深度学习的人体肋骨骨折智能检测技术

目的将人工智能中的深度学习技术应用到人体肋骨骨折识别,实现人体肋骨骨折智能检测,提高法医肋骨骨折诊断效率。方法采集3143例人体胸部X线数字影像(2602例用于训练,541例用于测试),标注肋骨骨折特征点,通过多层网络堆叠,分层、分级主动学习原始数据高度抽象的特征表述,并将此特征反馈至检测器进行骨折检测,输出骨折位置及相应置信度。结果基于深度学习的人体肋骨骨折检测准确率在90%以上。结论基于深度学习的人体肋骨骨折检测准确率较高,可用于辅助法医进行肋骨骨折识别诊断、检验鉴定等,本研究可为人体其他部位骨骼损伤智能检测提供参考。     

建构主义学习理论在英语教学中的应用

建构主义学习理论为英语教师提供了很好的借鉴作用。它强调学生的主体地位和教师的指导作用,注重学习情境的真实性、学习的协作性和对意义建构的独立性。这种理论指导下的教学方法——支架式教学、抛锚式教学和随机进入教学,对英语教学有很好的启示作用。     

Problem-based learning and international commercial dispute resolution in the Indian Ocean

One of the primary challenges for a law lecturer is to take students beyond their own assumptions about the parameters of a subject and provide them with new opportunities for exploration and a broader vision to enhance learning. A significant feature of law as a discipline of study in higher education that has the potential to impact on the curriculum and the way in which it is taught is the academic/vocational divide. Problem-based learning (PBL) activities make classroom settings unpredictable and surprising, and learning to deal with such uncertainty prepares students for one of the most crucial aspects of professional life: the ability to make judgements in a context of uncertainty. This article analyses the integration of PBL within an LLM module on International Commercial Dispute Resolution. The logic of using PBL in this module is to ensure that the more abstract and less engaging aspects of the course are learned in relation to a close involvement with problems that are highly relevant to students’ more concrete ideas of what the course is about and what competence would mean within it. The experience of the students with the PBL activities, captured in reflective narratives and anonymous questionnaires, is also discussed.     

Reasons why law students should have access to learning law through a skills-based approach

The Legal Education and Training Review identified gaps in law students’ key skills development and this paper considers how skills training in three key areas of mooting, negotiation and client interviewing can be maximised so that law students have a sense of themselves as lawyer as well as law student from the beginning of their legal education. The research identifies numerous benefits to learning law through skills-based activities, but also discovers some possible apprehensions about participating from a student perspective. This paper draws on data taken from students who engaged in short-term optional courses in client interviewing, negotiation and/or mooting and considers the responses to a survey conducted prior to participation, a reflective survey post-completion and a focus group exercise. In total 64 students responded to the questionnaire. The research explores the expected and actual benefits of participating in the courses, discusses how these impact on students’ perceptions of their employability and the types of activities considered most valuable. The article considers how, in light of the research, experiential learning can be put to best use within the law curriculum.
