For the inefficiency and inaccuracy of appraisal method of traditional estate appraisal theory, the real estate appraisal system based on GIS and BP neural network was established. The structure of the system was designed which includes appraisal model, trade case, GIS database and query analysis module. With the help of the L-M algorithm in MATLAB software, BP neural network was improved and the trade cases were trained, then the BP neural network which has already been trained was tested. At the same time, the BP neural and GIS were put together to construct the hedonic price estimate model. The C# and ArcGIS9.3 were used to achieve the system in VS2008. City basic geographic data and real estate related information were used as the basic data in practice. The results show that the functions of querying, adding and editing the spatial data and attribute data are achieved and also the efficiency and accuracy of real estate are improved, so that the new method of real estate is provided by the system. 展开更多

Aiming at the target of enhancing agricultural competitive power and maintaining the sustainable countryside development, "the three dimensional innovation", namely the system innovation, the organization innovation, and the service innovation, is the basic way to raise the efficiency of productive factors, optimize the organizational structure and enhance the farmers' own organizational ability, thus it becomes an important proposition in the fundamental research and practice of China new countryside construction. Through the reorganization and analyses of the domestic academic achievements, this article chose "the county innovation in China new countryside construction" as the first level index, and "the three dimensional innovation" as the second level index. Totally four levels of indices, namely the strategy level, the mechanism level, the carrier level and the comment level, were introduced to construct the county innovation appraisal system. The further adjustment and supplement of the indices and the choices of computational method must be completed through spot investigation and case study. 展开更多

This paper proposes an improved performance appraisal system (PAS) that is based on the philosophy of total quality management(TQM). It focuses on understanding the customer′s (both management and employees) requirements for the PAS in order to prioritize and simplify the basic elements of the appraisal system and implementation process. The improved process is defined by performance planning, counseling and evaluation with assessments for individual, team and management contributions. In addition, reducing the rating scale to three categories should facilitate a very positive evaluation process for most employees and still allow a constructive focus on those individuals that must be improved. Finally, if people come first in the TQM organization, then the personnel systems must reflect this philosophy. 展开更多

[Objective ] The study aimed at assessing the state of lake health. [ Method] Based on the concept of "healthy lakes" analyzed deeply, the fuzzy integrated evaluation was used to establish the evaluation index system of lake health, and the analytic hierarchy process (AHP) com- bined with expert evaluation method was used to determine the weight of each indicator. Afterwards, the health state of three typical lakes ( San- baidang, Beimayang and Qiaobeidang) in Wujiang City were evaluated by the system, and the measures to develop and protect the lakes were put forward finally. E Resultl The assessment results showed that Sanbaidang and Beimayang were in basic health, while Qiaobeidang was in sub- health. The indicator system and assessment method are suitable for the rivers in eastern plains of China.[ Conclusion] The research could provide scientific references for the development, protection and restoration of lakes. 展开更多

Appraisal is a major kind of discourse semantic resources construing interpersonal meaning, which includes three subsystems: attitude, engagement and graduation. Engagement resources are linguistic resources of inter- subjective positioning,through which writers or speakers open up or close down dialogic space for putative reader and try to align or disalign readers on the ground of solidarity. This study applies engagement system to analyze political commentaries. It focuses on the denial resources in detail. In political commentaries, by using denial resources, the commentator invokes, and then directly rejects different opinions or beliefs the putative readers may have. Through strategy of dialogic resources, commentators try to make up for disalignments caused by denial and form the grounds for solidarity. 展开更多
