The purpose of this paper is to explore the influence mechanism of job satisfaction and positive affect on knowledge sharing among project members in Chinese construction industry, and test the moderating role of organizational commitment between them in order to find a new approach from the perspective of psychology to improve the knowledge sharing performance within project management organizations in China constantly.

An empirical study was used based on confirmatory factor analysis and hierarchical regression analysis with a sample of 540 project members from 80 project management organizations in China.

Research results showed that job satisfaction and positive affect of project members both have a significant positive impact on knowledge sharing; organizational commitment could moderate the influence of job satisfaction and positive affect on knowledge sharing among project members partially within the Chinese context.

A questionnaire study from China only represents the relationship and regular pattern within a shorter time interval in the Chinese context. It is necessary to continue to implement a longitudinal study in a relatively long period in future research.

Knowledge sharing among project members can be enhanced through improving job satisfaction and positive affect, and strengthening project members’ organizational commitment can amplify the influence effect of job satisfaction and positive affect on knowledge sharing.

This paper clarifies the direct influence mechanism of project members’ job satisfaction and positive affect on explicit knowledge sharing (EKS) and tacit knowledge sharing (TKS), and further tests the partial moderating effect of organizational commitment on the influence relationship of job satisfaction and positive affect on EKS and TKS.

The study aims to compare and analyze the impact of the commonly used pallets (wooden pallet and plastic pallets), using life cycle assessment (LCA), then provide certain suggestions for the development of green packaging.

In this study, software Simapro was used to calculate and analyze the whole life cycle of pallets from the stage of raw materials and production to processing and waste disposal.

A total of 12 environmental categories were used to quantitatively analyze the environmental impact of the four different pallets. The results showed that, regardless of raw material, processing, or waste stage, the environmental impact of wooden pallet was lower than that of plastic pallet. Wooden pallet was better than plastic pallets.

This study compared and analyzed the pallet of 1 × 1.2m with different materials.

Green packaging is the development trend of the future packaging, which follows the principle of 3R1D. According to the calculation results, corresponding suggestions can be put forward from production, processing, using, wasting and other aspects, and make corresponding contributions to the development of green packaging.

The contribution and impact of each stage of the product on the environment can be studied. The environmental impact, such as global warming potential, water scarcity, can be reduced through different solutions such as the use of green materials, good processing techniques and higher recycling rates.

This study aims to compare and analyze the impact of the commonly used takeout packing (Kraft paper bowl and plastic bowl) through life cycle assessment, then certain suggestions for the development of green packaging could be provided.

In this study, Simapro software was used to calculate and analyze the whole life cycle of takeout packaging from the stage of raw materials, production and processing and waste disposal.

Twelve environmental categories were used to quantitatively analyze the environmental impact of the two different bowls. The results showed that the impact of Kraft paper bowl on the environment was less than that of plastic bowl, regardless of raw material, processing or waste stage. Kraft paper bowl was better than plastic bowl.

This study compared and analyzed the progress of 750-mL bowls made with different materials and specific specifications.

Green packaging is the development trend of the future packaging and follows the principle of reduce, resue, recycle, degradable. According to the calculation results, corresponding suggestions can be put forward from production, processing, use, waste and other aspects, and make corresponding contributions to the development of green packaging.

The contribution and impact of each stage of the product on the environment can be studied. The environmental impacts, such as global warming potential and water scarcity, can be reduced through different solutions, such as the use of green materials, good processing techniques and higher recycling rates.

Both glazing and laminating play a certain role in finishing and protecting the surface of printed matter. This study makes a comparative analysis of the two through life cycle assessment (LCA) and theoretically explores the difference between them.

In this study, the life cycle of laminating and glazing processes was calculated through using Simapro software, and the results were compared and analyzed.

Twelve environmental categories were used to quantitatively analyze the environmental impact of the product. The results showed that the results of the 12 environmental categories involved in the analysis of glazing was less than that of laminating, indicating that the impact of the glazing on the environment was less than that of laminating on the environment.

In order to simplify the study, we only calculated and analyzed the laminating and glazing.

Green packaging is the future, 3R1D, reduce, reuse, recycle and degradable. According to the calculation results, corresponding suggestions can be put forward from production, processing, use, waste and other aspects, and make corresponding contributions to the development of green packaging.

The contribution and impact of each stage to the product life cycle can be studied. In addition, different waste disposal methods have different impacts on the environment, and the higher the recovery ratio, the better the environmental benefits of the product. Recycling should then be promoted as proportionately as possible in practice in order to reduce the environmental impact .

The intelligent identification of stains can quickly and accurately identify stains. At present, stains are identified subjectively by appearance, color, taste, feel, location, etc. Color is an important factor in identifying stains. K/S value is used to analyze the color of textile fabric, and it has additivity. The purpose of the study is to explore its application in stain recognition is of great significance to intelligent washing.

A certain method used to stain the textile, then the K/S value of the textile before and after the stain was analyzed and tested by the color difference instrument. The K/S curve of the stain was calculated by the addition of K/S, and then the stain was identified and distinguished.

The K/S value of the textile stained with stains could be deducted by the K/S value of the color difference meter. After deducting the base cloth, the K/S curve of the same stain is basically the same. Then the stain can be identified and analyzed.

The K/S value can be used for stain analysis, but it needs to be analyzed and tested in the laboratory.

This study provides a simple method for stains identification.

In addition to common methods of stain identification, such as appearance, color, feel, smell, location, stain removal materials, breaking the substrate, IR, etc., K/S value can be used for stain analysis. Identifying stains and washing them in a targeted way to achieve a better washing effect could provide certain technical support for the development of smart washing and smart home appliances.

This paper traces the timeline and milestones of Chinese graduate students in agricultural economics and related fields at foreign universities, with an emphasis on North American universities, since the early 1980s, and assesses the contributions of Chinese doctoral recipients from foreign universities to agricultural economic research and education in North America and China.

Data from department and college websites, associations of agricultural economics, university libraries and databases of theses and dissertations and selected agricultural economic journals in English and Chinese are used to attain the above purposes through graphical and bibliometric analyses.

First, the numbers of Chinese doctoral recipients and tenure-track and tenured faculty in agricultural economics at North American universities have increased steadily and significantly. Second, Chinese scholars in North America have achieved tremendous success in agricultural economic research via high-quality publications, prestigious awards, editorship of top journals, leadership in professional organizations, etc. Third, more Chinese doctoral recipients overseas have increasingly returned to China and are playing important roles in China’s agricultural economic research, education and international collaboration. Fourth, the publications of overseas Chinese scholars in Chinese journals and those of their counterparts working in China on topics beyond China are relatively limited and more collaboration may enhance the global impacts of Chinese agricultural economists.

This research is limited by data availability and quality and the data problems are discussed in the paper.

This is likely the first study to assess the contributions of Chinese doctoral recipients from foreign universities to agricultural economic research and education in China and abroad.
