体育科学研究选题的基本原则和策略

能否恰当地选题，将对体育科学研究的成败和成果的价值大小起决定性作用，体育科学研究选题应遵循先进性，科学性，可行性和效能性等基本原则，并采取“空白点”选题，“争议点”选题，“交叉点”选题等多种选题的基本策略。     

刍议马克思哲学本体论的形上消解与重构

马克思哲学在哲学史上最具深远意义的革命变革，就在于它通过对传统哲学形上本体的批判、消解与重构，开创了哲学发展的新方向，奠定了哲学发展新形态的基础。马克思哲学终结了一切旧形而上学，但是并没有完全放弃关于“解释世界何以可能”问题的物质本体论寻求，而是更着力于“改变世界何以可能”，以寻求现实解放的道路。这一寻求“改变世界何以可能”的本体论诉求构成了马克思哲学的重要理论旨趣。     

现代社会所需要的人才知识结构与汉语言文学专业的课程设置

我们现在所处的时代是一个知识不断更新的时代，大学生的知识结构必须适应社会的需要。汉语言学专业既要保持一些经过长期考验的基本课程，又要努力增添时代和社会需要的新课程。通修课程应增添“现代科学技术概论”；大科共同基础课程可设置“中国化史”和“世界化史”；选修课可按照二级学科分成若干系列，尤其要注意开设实用技术的选修课。

Computed tomography using level set method and algebraic reconstruction technique

In this paper, a novel reconstruction technique based on level set method and algebraic reconstruction technique is proposed for multiphase flow computed tomography (CT) system. The curvature-driven noise reduction method is inserted into the conventional iteration procedure of algebraic reconstruction technique to improve the image quality and convergence speed with limited projection data. By evolving the image as a set of iso-intensity contours after each updation, the sufficient number of iterations for acceptable results is reduced by 80%-90%, while the image quality is enhanced obviously. Quantitative evaluation of image quality is given by using both relative image error and correlation coefficient. The resultant images can be utilized to detect flow regimes for monitoring industrial multiphase flow. Laboratory results demonstrate the feasibility of the proposed method. Phantoms of four typical flow regimes can be reconstructed from few-view projection data efficiently, and the corresponding image errors and correlation coefficients are acceptable for the cases tested in this paper.

Academic identity,confidence and belonging: The role of contextualised admissions and foundation years in higher education

This article presents a cross-national exploration of responses to widening participation (WP), with a specific focus on the provision of foundation year (FY) programmes and the use of contextualised admissions (CA) in selective Irish and UK institutions. There remains a dearth of research on these routes, with little understanding of the characteristics of students who utilise them, of why students use these routes and little knowledge of their effect on students’ experiences in university and their overall sense of belonging. A year-long longitudinal comparative case study design examined three alternative entry routes in two selective higher education institutions (HEIs) in England and Ireland: a well-established FY; a newly formed FY; and a CA pathway. Data were collected through a mixed-method approach. Questionnaires and in-depth focus groups were employed at fixed points with participating students in each route. Results indicated that FY students had lower levels of familial educational history and parental occupation. FY students’ sense of belonging significantly increased over the year, with students reporting increased confidence and sense of belonging due to the relationships established during the FY. CA students’ sense of belonging remained the same, with students reporting feeling different and isolated. Results indicate that while students utilising FYs may be ‘more disadvantaged’ than CA students, their experiences helped establish a sense of belonging; illustrating the need for diverse WP routes catering to a wide range of needs. Results highlight the importance of providing opportunities to develop social and bridging social capital for all non-traditional students.
