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.

A Case Study of an Experienced University EFL Teacher’s Use of POA Teaching Materials

Although research on teaching materials use has important implications for materials development,little literature examines how teachers actually use materials in the classroom.The present study,taking the theoretical framework for using and evaluating Production-Oriented Approach(POA)teaching materials(Wen,2017),explores the procedure and the rationale of an experienced Chinese university EFL teacher’s use of POA teaching materials.Multiple methods were employed in data collection,including classroom observations,teacher interviews,the teacher’s lesson plans,and PowerPoints,as well as students’written and oral products.Data analysis showed that the teacher followed a three-phase process of materials use.Before class,teaching objectives were set,materials were selected,adapted,and then transformed into teaching activities.During class,the teaching activities were implemented with the materials.After class,the effectiveness of using the materials was assessed.The study revealed that the teacher played an active role in practicing the essential POA principles of“productive-objectives-determined”and“input-in-service-to-output”in the entire process of material use.

A Pioneering Experimental Study on the Batch Crystallization of the Citric Acid Monohydrate

Citric acid is an important organic substance whose marketing concerns various fields. Nevertheless, until 1997 the scientific literature reported little information about the process of crystallization by cooling through which the commercial product is obtained. In particular, the available studies were aimed to investigate only the kinetics of nucleation and crystal growth neglecting some effective aspects of the industrial crystallization in mechanically stirred apparatus. In order to fill that sci-tech gap, the Department of Chemical Engineering at the University ＂La Sapienza＂ of Rome decided to lead a long and meticulous experimental research on the crystallization in discontinuous （batch） of CAM （citric acid monohydrate） in the allotropic form that is stable at room temperature. Due to the number of people involved in that pioneering work, carried out in the historic laboratories of＂La Sapienza＂ （Faculty of Engineering）, and motivated by the publication of related M.Sc. dissertations and research papers, such collective effort was called ＂School of Industrial Crystallization＂. Among the graduate students in Chemical Engineering that 17 years ago participated in that fruitful experience there was also the author who, under the supervision of Prof. Barbara Mazzarotta, had the specific task of assessing the effects on CAM of changing the crystallization operating conditions until their optimization; the achievements are briefly illustrated in this paper.

Study of non-revenue water status and enforcement measures to reduce water loss:case study in villages of Kermanshah Province of Iran

In this study, the volume and the cash value of water loss, and reduction of water loss as a result of enforcement action during 2011-2013 in the drinking water network of villages in Kermanshah Province, tran, have been investigated. Date collected by referring to the different parts of rural water and waste water company of Kermanshah Province and checklist were completed. The study showed the volume of produced water and sold water has increased and the water loss percentage has decreased. High cost of water production compared to revenue of sold water and water loss resulted in significant detriments in terms of the water production costs. Water loss level decreased from 33% to 30% as result of measures taken to reduce water loss but, it is still 15% higher than the world average level. Also the reduction in number of water resources and increase in the number and volume of reservoirs indicates a lack of water and a growing need. As result of high water loss, waste of costs in the contrast of water production cost and also because physical water loss accounts for most of the water loss of villages, necessary measures can be effective in reducing loss and have economic justification.

The intrinsic depth of horizontal convection

The mainstream depth of a return flow can be viewed as an intrinsic depth of horizontal convection. By using a theoretical tube model combined with the application of the Maximum Entropy Production Principle (MaxEPP) in thermodynamics, the following statements can be made. Under fixed external forcing, the system chooses a particular depth as the mainstream depth of its return flow, the depth of which not only satisfies the maximum circulation rate and the maximum heat transport, but also satisfies the maximum entropy production rate. A comparison between this intrinsic depth and the container height leads to the definition of a relative partial and full-penetration pattern of the circulation. Moreover, this intrinsic depth is found to vary with the external forcing; the regulation of this variation is related to the Modified Rayleigh number.

This paper proposes an integrated teaching system of animation to solve the contradiction between market demand and traditional animation teaching mode, making analysis and researches of the kind of integrated teaching system, which is briefly described.

Study on Water－Soluble Organic Reducing Substances：Ⅲ．Electrochemical Properties of Decomposition Products of Rice Straw and Their Interactions with Variable Charge Soils

Some electrochemical properties,such as PH,Eh,and voltammetric behavior,of the decomposition products of rice straw and the in eractions of these products with soils were studied.The PH,Eh,and amounts of organic reducing substances changed markedly during the 60-day anaerobic decomposition.pH decreased sharply to pH 5 on the tenth day and then increased gradually to 7 on the 45th day.The amouats of organic reducing substances increased almost synchronously with the fall of redox potential during the first 15 days.The differential pulse voltammetric(dpv) behavior changed not only in the peak current but also in the peak potential.The fractions with apparent molecular weights lower than 200 dations appeared to be active in dpv behavior.The electric charge of organic reducing substances was closely related to the decomposition stage.The 6th day of incubation was the crucial time before and after which the major part of the components was negatively charged and positively charged, respectively.The group with a low apparent molecular weight and a negative charge was the main components responsible for the lower anodic peak potentials.They were oxidized first during the interactions of the organic reducing substances with soils.

A Strategy to Strengthen the US Economy

For decades, the United States＇ competitive position in global manufacturing has steadily declined. Analysts point to increasingly automated manufacturing processes, changing domestic demand factors, outsourcing, and over confidence in service export surplnses. However, Asian and European competitors, undergoing the same pressures, have been able to maintain a healthy percentage of their GDP in manufacturing by growing high techjobs while the United States continues to fall behind, Perhaps the most flmdamental and overlooked contribution to this decline is the lackluster performance of the United States education system. After comparing the performance of US students to that of the other G-8 nations in the critical disciplines of math and science literacy, US students rank last. Furthermore, the most recent PISA test results show US students rank in the bottom half of 30 participating nations in the ability to apply math and science concepts to real world problems. This is particularly troubling when one considers that among the compared nations, the US spends the most on math and science teacher compensation. If the US intends to successfully compete in the global manufacturing arena, significant changes to the education system must be enacted. A new strategy aligning the system with real world demands should begin with a national initiative to increase Pre-K enrollments, a paradigm shift from liberal arts to math, science, problem solving and critical thinking, standardized policies aligning high school graduation requirements with college and work place expectations, and standardized college and career readiness assessment programs. These steps combined with more rigorous secondary education teacher certifications, continued education and involvement with universities and manufacturing f＇mns within the community, should more adeq^tely prepare high school students for further study or to enter the skilled workforce. At the post secondary level, federal and state funding should be targeted to R＆D programs specificly to industrial design, engineering, and alternative energy. Industry investment in such programs should be federally incentivized to foster cooperative relationships between business and academia. Such relationships will ensure faculty spend time focusing on how their discipline relates to manufacturing and instilling the necessary skill sets, knowledge and abilities which graduates will need to compete in the global market. Such a revised system will position the US to create and keep high paying manufacturing positions on its way to sustainable economic growth.

Applied research of mathematical models in enterprise product sale

Some products are only sold in some regions while some are sold in certain months, so there are a lot of data gaps. If we choose too much of this vacancy data, it may have impact on knowledge extraction. So to aim at specific sale database, we chose to study six kinds of representative products among them and these products are relatively comprehensive in all regions and month sales including two conventional products, two special products and two accessories; we also chose seven sale regions to make detailed analysis. We selected nine characteristics of sales in database which respectively are monthly sales volume, monthly revenue, monthly average selling price, profit, program sales volume, completed percentage of a program, sales month, sales territory and product type.

The Production of the Sequence -UI- by Francophone Learners of English

This paper considers the renderings of the sequence -UI- by Cameroonian, Gabonese, and native French users learning English with the view to finding out whether French users speaking different L 1s pronounce this sequence in different or similar ways. The data were recordings of items containing -UI- and the contrastive method of analysis was used. It was found that this sequence is rendered in two ways by the learners. Besides, different L2 French-speaking learners tend to pronounce it in the same ways and so do L2 and L1 French-speaking learners. It can therefore be hypothesised that Francophone speakers tend to draw more from French when they speak English than from their respective L 1s.

Effect of Three Different Growth Media on Yield and Oil Constituents of Rosemary （Rosmarinus officinalis L.） under Protected Agriculture Conditions

Medicinal plants provide an important source of cure since ancient time. Poor soil resources, scarce and saline water and the harsh environment limited the production of plants in the Arabian Gulf countries. This study aimed to investigate the production potential of rosemary （Rosmarinus officinalis L.） grown on different growth media under greenhouse conditions. Three growth media agricultural soil, compost and hydroponic system were used, whereas tuff （inert volcanic material） was used as substrate. The result indicated that the high salinity of the agricultural soil limited growth and oil yield in rosemary. Shoot height increased in 11 weeks, by 62%, 65% and 114% in plants grown in agricultural soil, hydroponic system and compost, respectively. Na content in plants grown in agricultural soil was significantly higher than in plants grown in the other treatment. Essential oil yield in plants grown in compost exceeded those in agricultural soil by 114%. Essential oil content （0.66%-1.5% w/w） and chemical constituents concentrations did not change significantly with growth media. The main constituents, more or less, are comparable to essential oils constituents reported from other countries. In comparison, better yields are obtained for individual components of the oils of plants grown under our green house conditions. This study demonstrated the great potential of commercial production of rosemary in the greenhouse without compromising the oil quality and oil yield.

Researches on the teaching based on the applied linguistics

Along with the development of the times and the innovation of the society, the history and cultures are also constantly inherited under the strike of the flow of the tide over the years, forming the centuries-old cultures. Of course, the heritage of any culture needs a carrier, and the history and culture is no exception. Language itself is a kind of tool for the information exchange, and the communication process of the language is also accompanied by the substitution of the culture. So it can be said it is not only the category of the information exchange, but should be expanded to the cultural heritage. With the continuous changes and development of the society, people focused more on the application in the learning of the language, so as to highlight the characteristics of different cultures through the applications in different aspects.

Animation art forms and aesthetic characteristics

In a very shocking symbol, animation art leads us to the continuing social and philosophical problems. With its unique hypothetical language as the human spirit and emotional material carrier, animation art passes various social messages to people. The value of animation art lies in the certain form of expression to convey characteristics of the content and spirit, which is the core issues that Chinese animation industry worthy of attention and research. Animation art as a cultural transmission symbols, bears culture spreading. The combination of cultural heritage and the new animation language means is an important way for animation art to direct towards the life of road. At the same time, let the excellent national culture and art forms combine with modem advanced technology and make innovation and creativity. Only in this way can China＇s animation talent with a new, unique appearance presented to the audience and occupy an important seat in the world animation art.

Analysis of Energy-saving Behavior among University Students in Vietnam

Currently, in the course of serious environmental problems where the cause is anthropogenic, such as global wanning, not only the technology and policies but also the promotions of pro-environmental behavior are required. However, previous studies reported a gap between high environmental awareness and behavior. So to promote this practice, it is necessary to clarify the determinants that lead to practice. Because of the rapid economic growth in developing countries, including Vietnam, pollution problems and energy consumption are of major importance. This study aims to propose methods to promote pro-environmental practices based on a questionnaire and statistical analysis that investigated university students in Vietnam＇s Ho Chi Minh city. From the factor analysis, in actions to do with the power-saving behavior of standby power and home electronics, and the use of air conditioning, four evaluation criteria including effectiveness, cost feasibility, convenience, and social norms are extracted. The covariance structure analysis showed that the evaluation of convenience represented the strongest causal relation to a given power-saving action, and the action, in turn, can lead to improvements in most practical activities so as to enhance their convenience. Finally, several methods to save energy are proposed based on the results of the questionnaire.
