Development of a DFN-based probabilistic block theory approach for bench face angle design in open pit mining

In open pit mining,uncontrolled block instabilities have serious social,economic and regulatory consequences,such as casualties,disruption of operation and increased regulation difficulties.For this reason,bench face angle,as one of the controlling parameters associated with block instabilities,should be carefully designed for sustainable mining.This study introduces a discrete fracture network(DFN)-based probabilistic block theory approach for the fast design of the bench face angle.A major advantage is the explicit incorporation of discontinuity size and spatial distribution in the procedure of key blocks testing.The proposed approach was applied to a granite mine in China.First,DFN models were generated from a multi-step modeling procedure to simulate the complex structural characteristics of pit slopes.Then,a modified key blocks searching method was applied to the slope faces modeled,and a cumulative probability of failure was obtained for each sector.Finally,a bench face angle was determined commensurate with an acceptable risk level of stability.The simulation results have shown that the number of hazardous traces exposed on the slope face can be significantly reduced when the suggested bench face angle is adopted,indicating an extremely low risk of uncontrolled block instabilities.

Optimizing Teacher-Student Collaborative Assessment in the Production-Oriented Approach:A Dialectical Research

Teacher-student collaborative assessment(TSCA)aims to address the challenges of responding to students’work in the Production-Oriented Approach:low efficiency and poor effectiveness.As part of a bigger project carried out in a Chinese university over a period of three years,the present study explored how the teacher prepared and implemented TSCA in class,especially with a focus on how she determined the assessing objective and worked collaboratively with her students in class to achieve it,using the students’written and translated texts as examples.By adopting the dialectical research(DR)method,this paper collected qualitative data such as teaching plans,classroom recordings,and reflective journals of the teacher-researcher(the author),along with students’written drafts and translated texts.TSCA theory and classroom practice have been refined simultaneously by means of putting theory into practice and reflecting upon it.The optimized pre-class and in-class procedures may shed some light on applying TSCA to L2 classrooms.

Effects of the Production-Oriented Approach on EFL Learners’Writing Performance in China’s Tertiary Education

The Production-Oriented Approach(POA)has been proposed as a remedy for overcoming the problem of input-output separation in the traditional text-centered teaching and learning paradigm in tertiary education in China.This two-week quasi-experimental study investigated the effect of the POA,compared with the traditional text-centered Intensive Reading Approach(IRA),on college students’L2 writing performance in terms of overall quality of the writing and its components of language,idea,and discourse structure.Data included writing samples of both experimental and control groups before and after classroom instruction and the results of a language achievement test on mastery of target language forms predicating students’language use in writing.The results showed that:1)no significant difference was found between the two groups either in the overall quality or in the“idea”and“structure”of the written texts;2)the experimental group outperformed the control group with respect to language use,in terms of both language quality and the frequency of target language use.These results indicated that the POA might have an advantage over the IRA in facilitating learners’writing development.

The Production-Oriented Approach Updated:Introduction to the Special Issue

More than a decade has passed since Wen Qiufang(2007)first proposed that foreign language teaching could benefit from output-driven practices in the classroom.Her original ideas were reformulated and further elaborated in the Production-Oriented Approach(POA),which aims to deal with the input-output separation in foreign language teaching in Chinese universities and colleges to optimize students’learning(Wen,2015,2016b).Integrating the strengths of Chinese traditional pedagogy and Western instructional approaches,this approach engages learners with production,merging the learning and use of language to enhance the efficiency of language teaching(Illes,2018,p.242)in a Chinese context.This introduction to the special issues includes three major sections.It starts out with an overview of what the POA system includes and how it works with a focus on its teaching procedures.The second section is about dialectical research(DR),a new research paradigm specifically designed for instructed second language acquisition(Wen,2017b)with“dialectical materialism as its philosophical basis”(Wen,2019,p.385).Finally,seven papers collected in this issue are introduced.We hope that this special issue sets a research agenda towards a better understanding of the POA.

A Study on Translation Approaches to Commercial Letters of Credit under the Guidance of Skopos Theory

According to the customs,by the end of 2011,the whole value of Chinese foreign trade is two thousand nine hundred and ninety four billion dollars,by the end of 2009,5 percents of the accounts of Chinese foreign trade with a value of fifty hundred billion dollars are unpaid.Most of the financial loss are caused by wrong translation of documents.The letter of credit is the most important way of payment in the international trade,so great attention should be paid to the translation of this type of document.Until now,the study against the translation of the letter of credit is scant.This paper will apply the skopos theory put forward by Hans Vermeer and developed in Germany in the late 1970s to guide the translation practice of the letter of credit.

Application of Literary Theory in Teaching Literature——A Case Study From ＂Approaching Fiction＂ in China Youth University of Political Studies

For most universities and colleges in China, literary theory is taught at the graduate level of literary studies. Most English teachers think literary theory is such a complex field with jargon-ridden disciplines and concepts that it is often considered as ＂a hot potato＂ in classroom teaching. Based on a case study from ＂Approaching Fiction＂ in China Youth University of Political Studies （CYUPS）, the present paper claims that application of literary theory in teaching literature not only greatly broadens students＇ horizon but also deepens their interpretation and understanding of literary works. With proper selection of teaching material and carefully designed teaching approaches, application of critical theory plays an increasingly important role in the undergraduate literature classroom.

Locke’s Tolerance Theory and the Workmanship Argument

John Locke’s tolerance theory involves the core issue of the relationship between reason and belief in the philosophy of religion.However,there is always controversy over whether the scope of adaptation of this theory is within a religion,between religions,or in a broader field.Considering that the overall moral approach of Locke’s philosophy requires the workmanship argument as a defense,and examining it from this point of view,it can be found that Locke’s efforts to transcend Creationism with this argument have resulted in a successful breakthrough,which makes tolerance not only a religion topic,but also a social principle.
