This paper takes listed companies in Shanghai and Shenzhen stock markets as research samples to analyze and test the relationship between executive career expectation and enterprise risk. This paper argues that manufacturing enterprise executive career expectations have a dual impact on corporate risk, one is to increase corporate risk through investment effect, the other is to reduce corporate risk through reputation effect. The results show that, in the two effects, reputation effect plays a leading role, that is, the higher the career expectation of executives, the more attention they pay to the professional reputation they try to build. In order to protect their own reputation from damage, executives pay more attention to the risk management and internal control of enterprises, so as to reduce the risk of enterprises. This also shows that reputation has a "implicit" incentive effect on executives .This study provides a theoretical basis for enterprises to formulate "explicit" and "implicit" incentive contracts.

At present, rural areas are becoming the second largest source of greenhouse gas emissions, and it is imperative to explore a low-carbon construction and development model suitable for rural areas.In view of insufficient vitality of rural public venues, through a combination of field visits and investigations, ArcGIS spatial analysis and related mathematical statistics, the service range index and service distribution index of rural public venues are created, and Shijiaying Village, representative of the Guanzhong Plain area, is selected as an example to analyze the spatial distribution of its public venues. It is found that rural public venues present the overall characteristics of unbalanced spatial distribution, which are mainly manifested in the following aspects: first, administrative village-level public venues have small effective service range; second, there are distinctive differences in service distribution between different villages; third, rural public venues lack service in overall. Factors such as the distribution pattern of rural settlements, the location layout and type of the venues exert an important impact on the spatial distribution of rural public venues. The study is expected to provide a useful reference for the planning and construction of rural public venues and the quality improvement of human settlements in China in the new era.

In recent years, with the development of manufacturing technology and production capacity, wind power industry has been developed rapidly.A new type of pin-cycloidal planetary reducer was proposed in this studyfor the actuator of the pitch of high-power wind turbines. Based on the transformation mechanism method, the transmission efficiency of the reducer was calculated by analyzing the pin-cycloidal meshing efficiency, bearing efficiency, and output mechanism efficiency. Prototype testing were combined to systematically and deeply study the design theory of the reducer for the pitch of high-power wind turbines. Finally, a new design was proposed for a reliable two-stage pin-cycloidal planetary reducer with a strong bearing capacity and multi-tooth meshing on the hard gear surface that can be applied to the pitch system of high-power wind turbines.

The financial performance should be evaluated from the perspective of stakeholders in higher vocational colleges firstly. And according to the development status of higher vocational colleges in recent years, a set of evaluation index of financial performance with characteristics of higher vocational colleges should be divided into five major dimensions: the performance of talents training, teaching performance, scientific research performance, performance of social services, logistics support performance. Hence, the financial performance evaluation model based on AHP and five major dimensions is established to solve the major theoretical and practical issues of financial performance evaluation and monitoring in higher vocational colleges. We also try to evaluate the financial performance of some benchmark industry and engineering vocational colleges applying the AHP model. Using statistical program R to analysis the panel data, the results show that the reasonable standards and clear directions can improve the financial performance in higher vocational colleges.

Abstract: Convolutional neural network based on attention mechanism and a bidirectional independent recurrent neural network tandem joint algorithm (CATIR) are proposed. In natural language processing related technologies, word vector features are extracted based on URLs, and the extracted URL information features and host information features are merged. The proposed CATIR algorithm uses CNN (Convolutional Neural Network) to obtain the deep local features in the data, uses the Attention mechanism to adjust the weights, and uses IndRNN (Independent Recurrent Neural Network) to obtain the global features in the data. The experimental results shows that the CATIR algorithm has significantly improved the accuracy of malicious URL detection based on traditional algorithms to 96.9%. Keywords: Malicious URL; CATIR; word vector feature; detection

Based on the in-depth study of the existing database synchronization model, in order to improve the cross platform ability of the system and facilitate the construction of small and medium-sized enterprise information platform, this paper proposes a heterogeneous distributed computing scheme based on Web service. The scheme uses JMS to realize the message transmission between systems, and uses web service technology to realize cross platform data reading and writing. In the aspect of distributed transaction processing, the two-phase commit protocol is improved to reduce the probability of system deadlock and effectively ensure the consistency of distributed database data. In order to improve the performance of distributed database system, cache technology is introduced, and the way of integrating cache and database transaction processing is proposed, which effectively ensures the validity of cache data. The architecture is oriented to program developers, who can develop efficient and convenient distributed database system on the basis of this architecture. Finally, this architecture is applied to the background management system of mobile express service. The running results show that the architecture can well meet the business requirements of distributed heterogeneous database system synchronization.

With the rapid increase in the sales scale of e-commerce platforms is accompanied by the rapid growth of consumer evaluation data on commodities at the same time. How to use big data analysis and visualization technology to mine the valuable information in the massive consumers evaluation data is an urgent issue in promoting the development of e-commerce platforms. However, the amount of e-commerce evaluation data is huge, growing fast, and mostly unstructured data, which is typical big data. In order to efficiently realize the visualization of e-commerce evaluation big data, this paper proposes an end-to-end four-layer framework for data visualization system. The data acquisition layer uses the Webcollector crawler to crawl a total of 420,000 mobile sales evaluation data on the JD website and stores them in the MySQL database; The data import layer uses the Sqoop tool to import MySQL data into the Hadoop platform; The data processing layer uses HDFS and MapReduce to process and analyze big data; The visualization implementation layer uses Jsp+Servelet+JavaScript+echart integrated technology to visualize the big data of distribution of mobile phone sales, user purchase impressions, and user mobile phone portraits. Which helps consumers choose their favorite mobile phones conveniently, and provide decision-making support for e-commerce companies to more accurately launch products, benefiting both parties
