It has been widely used at present in process-oriented writing instruction. In this paper, the researcher carried out an empirical study about the effects and efficacy of peer revision on a group of Chinese Juniors majoring in English. It was found that student writers focused specially on grammar and vocabulary in PE session and organization was the least attended to. PE was quite effective in improving the overall writing quality, as the participants did incorporate most of the revisions suggested by their peers. However, the influences of students'writing proficiencies and of the rhetorical modes of the writing tasks on the effects of PE were proved to be not very significant.展开更多

The foreign exchange earning is an essential industrial form of tilapia industry in Guangxi. Thus,enhancing the competitiveness of export-oriented tilapia processing is of great significance to the development of tilapia industry. On the basis of field survey,this paper analyzed current situation of export-oriented tilapia processing in Guangxi. At present,tilapia processing industry in Guangxi has realized preliminary standardization,large-scale and grouping,but it is still faced with some problems and challenges,such as low industrialization level,no balanced marketing,and imperfect product quality safety monitoring measures. Therefore,it is required to create favorable environment for export-oriented tilapia processing industry in Guangxi through enhancing policy support,increasing financial input and supporting tilapia processing leading enterprises.展开更多

First, problems and characteristics of knowledge sharing in multi-projects of chemical engineering design are analyzed. Then based on theories of project management, process management, and knowledge management, a process-oriented knowledge-sharing platform is proposed. The platform has three characteristics: knowledge is divided into professional knowledge and project management knowledge; knowledge sharing is integrated with the project process, which makes knowledge sharing a necessary part of the project process and ensures the quantity of knowledge shared; the platform provides quantitative measurements of incentive mechanisms for knowledge providers and users which ensures the quality of knowledge shared. This knowledge-sharing platform uses two knowledge management tools, a knowledge map and a knowledge base, to support the platform.展开更多

It is therefore important for the nurse to have the opportunity to reflect on the caring acts included in process-oriented nursing supervision (PRONS). The overall objective of the nursing supervision is to support the professional development identity, competences, skills and ethics in different situations in nursing care. Aim: To investigate nurses’ experiences of the model of purging, playing and learning (PPL) according to Eriksson theory in a (PRONS) related to strengthen safe care, quality and professional development. Method: A qualitative study with individual interviews and the data was analyzed using qualitative interpretive content analysis. Participants: All eleven registered participated nurses were from southwestern Sweden and worked in different hospital units. Ethical Considerations: The study carried out in accordance with the ethical guidelines laid down in the Helsinki Declaration and according to the recommendations of the regional ethics committee. Findings: Three categories were identified, valuable purging in the process, responsive playing and awareness of learning. The study found that by participating in PRONS the nurses had developed new approaches with different “tools” when difficult situations occurred in daily nursing practice. Conclusion: PRONS with the model PPL has an important role to support nurses in daily nursing practice. The study highlights that there are residual successful effects after PRONS for the nurses in managing care situations that experienced strengthen quality in care and professional development.展开更多

Constructive solid geometry cylindrical primitive is taken as work piece and modeling is accomplished for it. Response surface methodology is used to design the experiments and obtain statistical models for build time requirements corresponding to different orientations of the given primitive in modeller build volume. Contour width, air gap, slice height, raster width, raster angle and angle of orientation are treated as process parameters. Percentage contribution of individual process parameter is found to change for build time corresponding to different spatial orientations. Also, the average of build time requirement changes with spatial orientation. This paper attempts to clearly discuss and describe the observations with an aim to develop a clear understanding of effect of spatial variations on the build time for Fused Deposition Modelling process. This work is an integral part of process layout optimization and these results can effectively aid designers specially while tackling nesting issues.展开更多

To implement a real time simulation of Rectisol process, thermodynamic model and simulation strategy are needed. In this paper, a method of modified statistical associated fluid theory with perturbation theory is used to predict thermodynamic behavior of process. As Rectisol process is a highly heat-integrated process with many loops, a method of equation oriented strategy, sequential quadratic programming, is used as the solver and the process converges perfectly. Then analyses are conducted with this simulator.展开更多

The results show that the magnetic properties of cold rolled non-oriented electrical steel can be improved by controlling the annealing process to obtain uniform coarse grains with critical sizes after the recovery,recrystallization and growth of grains. Additionally,the annealing temperature influences the magnetic properties more significantly than annealing time,and with the increase of heating-up rate during the annealing process,the magnetic properties of the cold rolled non-oriented electrical steel increase.展开更多

The enterprise integration model depending on encapsulating the business processes as well as the enterprise applications by the neutral and standard web services is presented. The problem how to discover the existed enterprise resources and share them was resolved depending on the mechanism of publishing and discovering the services. The EIP is integrated closely with product lifecycle management (PLM) system so that the process integration as well as orchestration of the business process services is implemented by encapsulating the workflow engine of PLM system. Not only process integration and application integration, but also information integration based on the bill of material (BOM) conversion driven by process are achieved. Finally, an interpretive, qualitative case study on EIP is conducted for this research.展开更多

Skopos theory, as the best model that serves to the ends of professional translators, is taken as a basis for developing a logical framework of a research model. Within this context, the function of questionnaires in theoretical research is studied in such a way not only as to bridge the gap between practice and theory, but also in terms of their potentiality in yielding a causal research. In conclusion, this paper aims not only to unravel the ambiguous network between professional research conducted in translation process and questionnaires as tools of research, but it also discusses theoretical knowledge in terms of the logical framework they submit in research展开更多
