Investigating students' critical thinking in weblogs: an exploratory study in a Singapore secondary school

Qiyun Wang 서울대학교 교육연구소 2010 Asia Pacific Education Review Vol.11 No.4

Critical thinking is an essential competency in the new information age. But research shows that students commonly lack critical thinking skills and hence promoting students' critical thinking becomes crucial. This exploratory study investigated the extent to which secondary school students' critical thinking could be promoted by writing reflections in the weblog. Students' critical thinking was measured by using the Newman's model. Results showed that writing reflections in the weblog could help promote students' critical thinking and according to the Newman's model, three categories of critical thinking were promoted the most, they were bringing outside knowledge or experience (O+), relevance (R+), and justification (J+). In addition, the study also found that the types of interaction with peers and the teacher had a more positive effect on the extent of critical thinking. Implications for other research are discussed.

Effect of spiral spacing on axial compressive behavior of square reinforced concrete filled steel tube (RCFST) columns

Qiyun Qiao,Wenwen Zhang,Ben Mou,Wanlin Cao 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.31 No.6

Spiral spacing effect on axial compressive behavior of reinforced concrete filled steel tube (RCFST) stub column is experimentally investigated in this paper. A total of twenty specimens including sixteen square RCFST columns and four benchmarked conventional square concrete filled steel tube (CFST) columns are fabricated and tested. Test variables include spiral spacing (spiral ratio) and concrete strength. The failure modes, load versus displacement curves, compressive rigidity, axial compressive strength, and ductility of the specimens are obtained and analyzed. Especially, the effect of spiral spacing on axial compressive strength and ductility is investigated and discussed in detail. Test results show that heavily arranged spirals considerably increase the ultimate compressive strength but lightly arranged spirals have no obvious effect on the ultimate strength. In practical design, the effect of spirals on RCFST column strength should be considered only when spirals are heavily arranged. Spiral spacing has a considerable effect on increasing the post-peak ductility of RCFST columns. Decreasing of the spiral spacing considerably increases the post-peak ductility of the RCFSTs. When the concrete strength increases, ultimate strength increases but the ductility decreases, due to the brittleness of the higher strength concrete. Arranging spirals, even with a rather small amount of spirals, is an economical and easy solution for improving the ductility of RCFST columns with highstrength concrete. Ultimate compressive strengths of the columns are calculated according to the codes EC4 (2004), GB 50936 (2014), AIJ (2008), and ACI 318 (2014). The ultimate strength of RCFST stub columns can be most precisely evaluated using standard GB 50936 (2014) considering the effect of spiral confinement on core concrete.

Trade Openness and Gender Wage Gap : The Impact of Competition on Sectoral Wage Differences

Qiyun Feng 한국무역연구원 2015 무역연구 Vol.11 No.4

This paper which is based on the visual angle of differences in market competitiveness and refers to the theoretical model of the influence of trade openness on the gender wage gap makes a verification by using income distribution survey data in China. Through the verification, gender wage gap is divided into three skill groups, namely, high-skill, mid-skill and low-skill, depending on education level. The conclusions are as follow. First, the influences of trade openness on gender wage gap in uncompetitive sector and competitive sectors are different. Second, the influences of trade openness on these three skill groups are different. Third, technical development enlarges the difference of gender wage between the high- and mid- skill groups and abridges that in the low- skill groups. Finally, regardless of whether the measurement of trade openness is in importation or exportation, the trade influence on gender wage gap is of the same direction. The results of this paper are of great political significance, especially in aspects of females education and improvement of skills. Therefore, it is essential to provide opportunities for females in aspects of education and skills training ,in order to lessen the gender wage gap and fully take advantage of trade openness opportunities.

Axial compressive behavior of special-shaped concrete filled tube mega column coupled with multiple cavities

Qiyun Qiao,Haipeng Wu,Wan-Lin Cao,Hongying Dong,Jianwei Zhang 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.23 No.6

The compressive behavior of special-shaped concrete filled tube (CFT) mega column coupled with multiple cavitiesis studied by testing six columns subjected to cyclically uniaxial compressive load. The six columns include three pentagonal specimens and three hexagonal specimens. The influence of cavity construction, arrangement of reinforcement, concrete strength on failure feature, bearing capacity, stiffness, and residual deformation is examined. Experimental results show that cavity construction and reinforcements make it possible to form a combined confinement effect to in-filled concrete, and the two groups of special-shaped CFT columns show good elastic-plastic compressive behavior. As there is no axial bearing capacity calculation method currently available in any Code of practice for special-shaped CFT columns, values predicted by normal CFT column formulas in GB50936, CECS254, ACI-318, EC4, AISCI-LRFD, CECS159, and AIJ are compared with tested values. The calculated values are lower than the tested values for most columns, thus the predicted bearing capacity is safe. A reasonable calculation method by dividing concrete into active and inactive confined regions is proposed. And high accuracy shows in estimating special-shaped CFT columns either coupled with multiple cavities or not. In addition, a finite element method (FEM) analysis is conducted and the simulated results match the test well.

Application of PSO-SVM based Text Classification on the Precision Marketing of Insurance

Li Qiyun,Wan Ping,Hao Tianxu 한국무역경영학회 2022 한국무역경영연구 Vol.- No.28

Precision marketing is a new marketing concept put forward by the insurance industry in the field of marketing in recent years. In the context of the big data area, massive data provides a solid scientific basis for precision marketing. Particularly, the text classification algorithm is used to classify consumers' behavior habits and insurance preferences, which provides new possibilities for insurance marketing. However, the accuracy of traditional text classification algorithms is usually not high because of the high text features and sparse features. This article first introduced the particle swarm optimization (PSO) on the support vector machine (SVM) to optimize parameters and select the best parameters to use SVM to classify, and then the accuracy of the algorithm is applied to the HeXun BBS with insurance precision marketing scenarios, and carries on the forecast analysis for the user's consumption behavior, provide a quantitative basis for establishing a targeted marketing strategy, and also to verify the effectiveness of the PSO - SVM on the text classification.

Judicial Review on Turning Internet Service Provider Accomplice into the Perpetrator

Fu Qiyun 중국지역학회 2023 중국지역연구 Vol.10 No.4

In view of the serious social harm caused by internet service providers' assistance to the third party’s tortious act, the Ninth Amendment to the Criminal Law added the crime of refusing to fulfill the information and network security management obligation and the crime of providing assistance in criminal activities via information network, and turning ISP's accomplice into the perpetrator. Meanwhile, through the examination of the legislative text of the Ninth Amendment to the Criminal Law and ISPs who bear and do not bear criminal liability respectively in the cases of infringement of copyright of film and television works by Tianjin "Jiji Cinema" and the case of infringement of copyright of written works by Shanghai Zhiqi Investment Consulting Co., Ltd., it is found that the lack of legislation on this function and it’s in conflict with the judicial practice, which shows a state of anomie. The state of anomie, specifically embodied in the criminal law, which ignores the judicial application of the possible competing charges, ISPs to assume criminal liability for third-party prosecution procedures on the dependence of ISPs to independently assume criminal liability, and the lack of ISPs from the administrative penalties to the criminal accountability procedures of the scientific mechanism. Therefore, on the basis of adhering to the problem orientation, it is possible to establish a recourse procedure for ISPs to independently assume criminal liability in judicial practice, establish a special administrative review mechanism for ISPs to transfer the criminal liability procedure, construct a strict scientific procedure for the transfer of administrative penalties to the criminal liability of ISPs, and amend the existing criminal law norms at the legislative level in accordance with the theory of "division of labor + role" and "complicity". Optimization paths, such as amendments to existing criminal law norms at the legislative level in accordance with the "division of labor + role" theory of complicity, and other optimization paths, provide mechanism safeguards for the application of accomplice into the perpetrator.
