任务驱动教学法在数控加工实习教学中的应用

采用以项目为引导,以任务为驱动的任务驱动教学法,强调在教学过程中不断用任务来引导学生自学,让学生根据任务的需求来学习,变被动地接受知识到主动地寻求知识,强化和引导学生的探究性学习,从而让学生获得职业知识,培养出学生的创新能力和独立分析问题、解决问题的能力,成为具备一定的专业理论基础知识和较强的实践技术的实用型、技能型高职人才。以典型轴类零件的数控车削加工为例,探讨了任务驱动教学法在数控加工实习教学中的实施方法和步骤。     

New stability and stabilization conditions for stochastic neural networks of neutral type with Markovian jumping parameters

This paper discusses the stabilization criteria for stochastic neural networks of neutral type with both Markovian jump parameters. First, delay-dependent conditions to guarantee the globally exponential stability in mean square and almost surely exponential stability of such systems are obtained by combining an appropriate constructed Lyapunov–Krasovskii functional with the semi-martingale convergence theorem. These conditions are in terms of the linear matrix inequalities (LMIs), which can be some less conservative than some existing results. Second, based on the obtained stability conditions, the state feedback controller is designed. Finally, four numerical examples are provided to illustrate the effectiveness and significant improvement of the proposed method.     

From Exclusion to Inclusion: Changes in Women’s Roles in Folk Sports and Indigenous Physical Culture in China

Abstract

The physical culture of Chinese folk sports is embedded in religions and rituals that have been predominantly ruled by men. However, this situation has been changing as the forms and meanings of folk sports transform in modern China. Based on the literature and interviews, in this research, the Funeral Dance of the Tujia ethnic group was considered as a case to explore how gender roles in Tujia indigenous physical activity changed during the modernizing process. Given the transformation of Funeral Dance from an indigenous funeral ritual to a national fitness programme and public and commercial performances, Tujia women have gained social access, legal status, national identity, and value, allowing them to participate in the dance. Policy interventions, capitalist drive, and social progress constituted an integral force that has systematically challenged the engendered nature of Chinese folk sports. Nevertheless, in Tujia’s conceptual framework, there is an invisible curtain between the stage and backstage of Funeral Dance performances. In the ‘front’, the participation of women is fully encouraged; however, ‘backstage’, the gender taboo remains as a so-called sporting tradition. The inclusion of both genders in folk sports is an unavoidable tendency in China, though the gendered boundaries continue to impact on women’s participation.
