To study a class of boundary value problems of parabolic differential equations with deviating arguments, averaging technique, Green’s formula and symbol function sign(·) are used. The multi dimensional problem was reduced to a one dimensional oscillation problem for ordinary differential equations or inequalities. Two oscillatory criteria of solutions for systems of parabolic differential equations with deviating arguments are obtained. 展开更多

This study involved in a 4-week experiment. Pre-and post-writing tests were quantitatively analyzed to examine whether the explicit instruction about DCs had a significant effect on the students'argumentative writing. The findings revealed that the ex-plicit instruction of the target DCs facilitated the improvement of the participants in their argumentative writing . 展开更多

In this paper, the stability and bifurcation behaviors of a predator-prey model with the piecewise constant arguments and time delay are investigated. Technical approach is fully based on Jury criterion and bifurcation theory. The interesting point is that the model will produce two different branches by limiting branch parameters of different intervals. Besides, image simulation is also given. 展开更多

In this paper, we investigate the existence, uniqueness and the asymptotic equiv- alence of a linear system and a perturbed system of differential equations with piecewise alternately advanced and retarded argument of generalized type (DEPCAG). This is based in the study of an equivalent integral equation with Cauchy and Green matrices type and in a solution of a DEPCAG integral inequality of Gronwall type. Several examples are also given to show the feasibility of results. 展开更多

The oscillations of a class of vector parabolic partial differential equations with continuous distribution arguments are studied.By employing the concept of H-oscillation and the method of reducing dimension with inner product,the multi-dimensional oscillation problems are changed into the problems of which one-dimensional functional differential inequalities have not eventually positive solution.Some new sufficient conditions for the H-oscillation of all solutions of the equations are obtained under Dirichlet boundary condition,where H is a unit vector of RM. 展开更多

The primary concern of this paper is to address the issue of discrepancies between teachers intuitively defined stronger and weaker student argumentative writings.There exists a problem in Chinese university EFL writing classrooms that the teachers'remarks on student compositions are often found to be rather vague or even unhelpful.Remarks such as Needs further amendment and You wrote just like the way you speak cannot supply students with explicit reasons of what is really needed for their writing improvement.Affirming the dialectal view on text-context relationship held by Systemic Functional Grammar(SFG),the theoretical propositions of Rich Feature Analysis(Barton,2004) are contended to a sound solution to the problem proposed by this paper.To demonstrate its feasibility,the paper followed the gist of Rich Feature Analysis to analyze a corpus of four argumentative writings on same topics.The paper consolidates "the spoken-written continuum"(Barton,2004,p.64),and concludes stronger argumentative writings should own at least one of the following properties: product-like,condensed,recursive,coherent,distanced,and open to scrutiny.The absence of lexical density and nominalization constitutes the main reason for writing deficiencies by tertiary students.The implications for learning the register of schooling are discussed. 展开更多

The Syllabus for English Majors at Universities and Colleges(2000) makes it clear to further strengthen the English majors' critical thinking and logical reasoning ability.But how to effectively incorporate the cultivation of critical thinking skills into English majors' core courses,such as the writing courses,remains one of the most important tasks of teaching reform for English majors.The present study is aimed at having a systematic analysis on the causal reasoning deficiencies in English majors' argumentative writing.Furthermore,the reasons resulting in the causal reasoning deficiencies and the implications for the teaching of second language writing are explored. 展开更多

It is known that writing is one of the main basic language skills and is very important for the ESL learners.However,writing skill is normally the more complex and challenging one,especially for Chinese ESL learners.A successful written discourse is influenced by a variety of elements and the good use of cohesive device is one of them.In this paper,by using the Halliday&Hasan’s taxonomy of cohesive devices as the framework,the features of cohesive devices which Chinese ESL learners have adopted in their argumentative writings will be analyzed and identified. 展开更多
