An Adaptive Finite Element Method Based on OptimalError Estimates for Linear Elliptic Problems

The subject of the work is to propose a series of papers about adaptive finite element methods based on optimal error control estimate. This paper is the third part in a series of papers on adaptive finite element methods based on optimal error estimates for linear elliptic problems on the concave comer domains. In the preceding two papers (part 1 : Adaptive finite element method based on optimal error estimate for linear elliptic problems on concave comer domain; part 2:Adaptive finite element method based on optimal error estimate for linear elliptic problems on nonconvex polygonal domains), we presented adaptive finite element methods based on the energy norm and the maximum norm. In this paper, an important result is presented and analyzed. The algorithm for error control in the energy norm and maximum norm in part 1 and part 2 in this series of papers is based on this result.     

Images of reflection: a look and a review

The idea of reflection linked with teaching has a wide semantic array in educational enquiry. In the preceding papers, it has been called reflective teaching [Russell] and reflectivity [Bullough & Gitlin]. While neither of these terms has received any great prominence in Australia, the term “reflection” itself has several images. This paper looks at these images of educational enquiry based on reflection and reviews significant issues that have emerged in Australian research, indicating how these are related to the papers in this issue of QSE.     

Different Strategies,Different Outcomes? The History and Trends of the Inclusive and Special Education in Alberta (Canada) and in Finland

This study compares the strategies and delivery of education for students with special educational needs in the province of Alberta, Canada, and in the country of Finland, in the European Union. The rationale for comparing these two jurisdictions is grounded by the idea that both of these areas have high general standards of living, a well-developed public education system, and top results in international school achievement tests. The data consists of available educational policy papers, previous research papers, and educational statistics. This article first describes the special education system development and the current situation, followed by the funding system and discussion about the implications and outcomes of different policies. The historical analysis shows that while many similarities exist between Alberta and Finland, there are also some culturally-bound elements present that have strongly affected the progress and the decision-making process related to the organization of the education for students with special needs.

Concept modeling of tapered thin-walled tubes

This paper presents a method to create concept models for the tapered thin-walled tubes using beam elements and spring elements. Developed concept tapered beam models with different taper angles and cross sections are compared with those detailed models through impact analyses. Important crash results are recorded and compared, and the relatively good agreement is achieved between these analyses. Concept modeling steps are illustrated in detail, and a general concept modeling method for such thin-walled tubes is summarized and presented.     

“给予”动词的语义和语用研究

给予动词语义上要求携带三个强制性语义成分,不同语域的动词对强制性语义成分在生命度、空间度、动词主体成分与与体成分之间的定向控制关系上有不同要求。不同动词的强制性语义成分映现为句法成分时有完全映现和不完全映现两种映现方式,句式的不同实际上反映了不同的功能要求。不同给予动词的强制性语义成分在省略、移位、变换等语用变化上也有不同特点。
