The purpose of this paper is to investigate Chinese teachers’ attitudes toward performance pay. Specifically, this study examined the extent to which Chinese teachers supported performance-pay programs. The study also examined the effects of these programs on teachers, particularly on their levels of collaboration, work motivation, and job stress.

This research was conducted in a northeastern city of China. Criteria sampling and maximum variation sampling techniques were used to select three schools, representing different characteristics of teacher performance pay (TPP) programs. In all, 150 questionnaires were administered to each of the three schools. The questionnaire contained three parts. Part 1 asked about respondents’ overall attitude toward pay-for-performance in general. Part 2 was composed of 20 closed-ended items asking respondents to rate their levels of agreement with various aspects of implementation of performance pay. Part 3 of the questionnaire comprised open-ended items.

Approximately 48.5 percent of the teachers supported the teacher-performance-pay programs. This indicated a low support of Chinese teachers in comparison to that in some countries. Regarding how teachers’ attitudes toward performance pay are related to teacher characteristics (e.g. teaching experience, professional ranking), the ANOVAs results showed no significant differences in any of the factors. This quantitative result was different from the qualitative result of this study (e.g. veteran teachers complained about the implementation of performance pay). In spite of the differences between quantitative and qualitative findings, some findings from the current study are consistent with those found in western countries.

One limitation of this study was the small sample size for quantitative analyses. Future research should consider a larger sample size to conduct more advanced statistical analyses such as structural equation modeling to examine further the relations among, for example, how much the incentive pay should be, and what proportion of teachers should receive it, the level of teacher stress, their work enthusiasm, and peer relationships. Another limitation of this study was that the qualitative data were collected through open-ended questions of the questionnaire. Future research should interview teachers and principals to obtain richer voices from the teachers.

Very few articles published in Chinese journals surveyed the implementation of TPP. In addition, these few articles were not well-designed from an empirical sense. So far research of teacher opinions about performance pay was a missing area in China’s educational discourse. The present study provides information to non-Chinese readers who are interested in Chinese teachers’ attitudes toward TPP. It is hoped the present study adds knowledge to the literature of TPP from the perspective of Chinese teachers.

To examine the relationship between online comments, merchant replies and online sales of tourism products and focus on the moderating role of tourist destination.

This article uses crawler technology and regression analysis methods.

The researchers found the following: (1) The number of pictures uploaded with online comments, the number of merchant replies and the length of merchant replies have a significant positive effect on sales of tourism products, while the length of comments and the similarity of merchant replies negatively affect sales of tourism products. The emotional scores of the reviews do not significantly affect sales of tourism products. (2) Tourist destination moderates the relationship between user comments and sales of tourism products. The length of comments has a greater negative effect on sales of domestic tourism products, while the number of comments has a greater positive effect on sales of overseas tourism products. (3) Tourist destination moderates the relationship between merchant replies and sales of tourism products. Consumers who choose domestic tourism products pay more attention to the interactivity reflected by merchant replies (e.g. number and length of merchant replies), while consumers who choose overseas tourism products hope to receive replies that are more useful, such as reply similarity.

The research conclusions enrich the relevant research in the field of online review research and has practical significance for how companies increase sales of tourism products.

This study aims to fabricate a cool phthalocyanine green/TiO₂ composite pigment (PGT) with high near-infrared (NIR) reflectance, good color performance and good heat-shielding performance under sunlight and infrared irradiation.

With the help of anionic and cationic polyelectrolytes, the PGT composite pigment was prepared using a layer-by-layer assembly method under wet ball milling. Based on the light reflectance properties and color performance tested by ultraviolet-visible-NIR spectrophotometer and colorimeter, the preparation conditions were optimized and the properties of PGT pigment with different assembly layers (PGT-1, PGT-3, PGT-5 and PGT-7) were compared. In addition, their heat-shielding performance was evaluated and compared by temperature rise value for their coating under sunlight and infrared irradiation.

The PGT pigment had a core/shell structure, and the PG thickness increased with the self-assembly layers, which made the PGT-3 and PGT-7 pigment show higher color purity and saturation than PGT-1 pigment. In addition, the PGT-3 and PGT-7 pigment showed 11%–16% lower light reflectance in the visible region. However, their light reflectance in the NIR region was similar. Under infrared irradiation the PGT-5 and PGT-7 pigment coating showed 1.1°C–3.4°C and 1.3°C–4.7°C lower temperature rise value than PGT-1 pigment coating and physical mixture pigment coating, respectively. And under sunlight the PGT-3 pigment coating showed 1.5–2.6°C lower temperature rise value than the physical mixture pigment coating.

The layer-by-layer assembling makes the core/shell PGT composite pigment possess low visible light reflectance, high NIR reflectance and good heat-shielding performance.

To explore the economical and reasonable semi-rigid permeable base layer ratio, solve the problems caused by rainwater washing over the pavement base layer on the slope, improve its drainage function, improve the water stability and service life of the roadbed pavement and promote the application of semi-rigid permeable base layer materials in the construction of asphalt pavement in cold regions.

In this study, three semi-rigid base course materials were designed, the mechanical strength and drainage properties were tested and the effect and correlation of air voids on their performance indexes were analyzed.

It was found that increasing the cement content increased the strength but reduced the air voids and water permeability coefficient. The permeability performance of the sandless material was superior to the dense; the performance of the two sandless materials was basically the same when the cement content was 7%. Overall, the skeleton void (sand-containing) type gradation between the sandless and dense types is more suitable as permeable semi-rigid base material; its gradation is relatively continuous, with cement content? 4.5%, strength? 1.5 MPa, water permeability coefficient? 0.8 cm/s and voids of 18–20%.

The study of permeable semi-rigid base material with large air voids could help to solve the problems of water damage and freeze-thaw damage of the base layer of asphalt pavements in cold regions and ensure the comfort and durability of asphalt pavements while having good economic and social benefits.
