Low efficiency in teaching and time-consuming in writing evaluation are two big problems for college English teachers.Therefore,it is necessary to create a new teaching model to solve these problems existing in traditional classroom-based teaching.This research adopts the research methods of test comparison before and after the students’composition experiment,questionnaire and semi-open interviews.Empirical research on a new teaching model that integrates the intelligent composition review and reform system represented by Piangai.com and the collaborative evaluation of teachers and students is conducted.The research results show that the new writing teaching model improves the quality of students’writing,promotes students’learning initiative,and enhances students’writing self-efficacy.This writing teaching model provides ideas for solving the problem of time-consuming and inefficient English writing teaching in large classes. 展开更多

Mekong River is one of the major international freshwater sources in the world. The Lower Mekong Basin (LMB) comprised of four downstream countries, including Thailand, Lao PDR, Cambodia, and Vietnam. The utilization of the basin’s water brings not only substantial benefits to the region ranging from hydropower to navigation, but also negative impacts caused by the unbalanced water using. The essential role of Mekong River requires all member nations to cooperate effectively for the sustainable development of the region. One of the most popular methods in the field of water resource management is a trustable tool called the Analytical Hierarchy Process (AHP). AHP is much appropriate for water resource policymaking. The literature, however, points out that there is no study to both structure the water using hierarchy and employ quantitative (objective) criteria to the AHP model in LMB case. With regard to water resource management, there are no previous studies applying AHP models to evaluating sustainable development of transboundary water resource in LMB case. This paper explores the evolution of water cooperation among Mekong countries and subsequently evaluates the water development scenarios in the LMB based on the water cooperation preferences of four LMB countries This study proposes a novel approach to analyzing, assessing water resource development scenarios characterized by sustainability indicators and to assisting in developing a suitable water policy in LMB according to the best cooperation scenario. 展开更多

On the basis of AHP method,this paper establishes comprehensive evaluation model of demonstration farmers' specialized cooperatives,uses the Delphi method and AHP software to assign scientific and objective weight to 7 criteria in criteria layer and 27 indices in index layer,and evaluate the overall level of 153 farmers' specialized cooperatives whose main business is fruits and vegetables in Region R.The results show that the overall operation level of farmers' specialized cooperatives is common;democratic and financial management is open;the information-based level and social sensation are not insufficient;the marking results of questionnaire is basically scientific and objective.This paper discusses the new way to evaluate operation level of farmers' specialized cooperatives,and puts forward relevant countermeasures and suggestions as follows:promote the information-based level of demonstration cooperatives;strengthen the service capacity of demonstration cooperatives;use means of science and technology to promote product quality;amplify social sensation of farmers' specialized cooperatives. 展开更多

The study focuses on assessing the financial management practices and accounting mechanisms in agricultural cooperatives in Tulsipur Sub-Metropolitan,Dang District,Nepal with a focus on understanding their implications for financial performance and organizational effectiveness.The sample size of total cooperatives(n=46)was divided into Savings and Credit Cooperatives(n=18)and Multipurpose Cooperatives(n=28),respectively,with a total number of respondents(n=138)categorized into managing directors,employees,and general members.Using a mixed-methods approach that combines quantitative analysis of financial data with qualitative insights gathered through interviews and surveys,the study emphasizes the importance of modern financial practices,improved reporting mechanisms,and relevant staff training for long-term sustainability.Recommendations include the integration of criteria and evaluation tools to assess cooperative performance,with Hamro Pahunch Multipurpose Cooperative identified as a high performer.Emphasizing the need for robust financial management strategies to navigate the complexity of the agricultural sector,manage risks,and achieve sustainable development,the study notes frequent preparation of financial management reports on a monthly and annual basis,and predominantly annual accounting management.Most cooperatives are using computerized models to present financial positions,but face challenges such as lack of marketing infrastructure,cooperative skills,and technical support.Ultimately,the study advocates for educating policy makers,cooperative leaders,practitioners and stakeholders on the role of effective financial management and accounting in enhancing the resilience,expansion and socio-economic impact of agricultural cooperatives,thereby fostering their long-term prosperity and viability as drivers of rural development and empowerment. 展开更多

By introducing development situation of specialized cooperatives and vegetable specialized cooperatives in China,this paper discussed existing problems in the process of development of China's vegetable specialized cooperatives. Then,it made efficiency evaluation on typical vegetable specialized cooperatives in 3 districts of Chongqing Municipality by the DEA method. Considering traditional DEA model has drawbacks,it introduced super efficiency DEA model to make complete identification and ordering of cooperatives. On this basis,it divided efficiency value into pure technical efficiency and scale efficiency,and classified cooperatives into 4 categories according to efficiency characteristics of non-complete effective cooperatives. Finally,it came up with recommendations and countermeasures for improving efficiency of specialized cooperatives from raising technical level and increasing members of specialized cooperatives. 展开更多

On the basis of expounding the necessity of evaluation index system of farmers' cooperative economic organization,the three first level indexes including organization development index,member development index and social development index and 13 second level indexes including aggregate capital of cooperative organization,annual profit share of cooperative organization,annual total income of cooperative organization,etc.,are established according to the principles of Systematics and the methods of Statistics and Quantitative economics.By using the analytical hierarchy process,the weight of each index is tested and the operation result and evaluation mode is established,as well as the index standard value and comprehensive value.As for the result of the evaluation,it is suggested that the government should support the farmers' cooperative organizations in hierarchy and targeted way according to local conditions.Though the construction of index system and comprehensive score,the government should establish the entry and exit mechanism of farmers' cooperative organizations to reasonably guild the rapid development of cooperators. 展开更多
