Purpose – The purpose of this paper is to analyze the impact of cross-border e-commerce platform brand image on brand trust, brand attitude, and brand loyalty. Design/Methodology/Approach – The study collected data on 273 customers with experience using cross-border e-commerce platforms. Statistical programs SPSS 27.0 and AMOS 26.0 were used for data analysis. The empirical analysis consisted of frequency analysis, confirmatory factor analysis, and hypothesis testing, in that order. Findings – First, the analysis results indicate that the three dimensions of brand image in cross-border e-commerce platforms, namely product image, corporate image, and service image, have a direct positive impact on brand trust. Second, three dimensions of brand image in cross-border e-commerce platforms, namely product image, corporate image, and service image, have a direct positive impact on brand attitude. Third, the research analysis results indicate that brand trust has a positive impact on brand attitude, and both brand trust and brand attitude have a positive impact on brand loyalty. Research Implications – First, cross-border e-commerce platforms face consumers from around the world. Platforms should treat customers with integrity, maintain a good reputation, and strive to gain positive word-of-mouth from consumers. Second, consumers place great importance on the quality of imported products, and whether goods purchased from the cross-border e-commerce platform are genuine. Therefore, cross-border e-commerce companies should ensure that the overseas products they sell are authentic, and establish platform policies and regulations to crack down on businesses selling counterfeit and inferior products.

Jiaming Xie,Xingyou Huang,Lingbing Bu,Hengheng Zhang,Farhan Mustafa,Chenxi Chu 한국광학회 2020 Current Optics and Photonics Vol.4 No.3

Multiscattering occurs when a laser transmits into dense atmosphere targets (e.g. fogs, smoke or clouds), which can cause depolarization effects even though the scattering particles are spherical. In addition, multiscattering effects have additional information about microphysical properties of scatterers. Thus, multiscattering can be utilized to study the microphysical properties of the liquid water cloud. In this paper, a Monte Carlo method was used to simulate multi-scattering transmission properties of Lidar signals in the cloud. The results showed the slope of the degree of linear polarization (SLDLP) can be used to invert the extinction coefficient, and then the cloud effective size (CES) and the liquid water content (LWC) may be easily obtained by using the extinction coefficient and saturation of the degree of linear polarization (SADLP). Based on calculation results, a microphysical properties inversion method for a liquid cloud was presented. An innovative multiscattering polarization Lidar (MSPL) system was constructed to measure the LWC and CES of the liquid cloud, and a new method based on the polarization splitting ratio of the Polarization Beam Splitter (PBS) was developed to calibrate the polarization channels of MSPL. By analyzing the typical observation data of MSPL observation in the northern suburbs of Nanjing, China, the LWC and CES of the liquid water cloud were obtained. Comparisons between the results from the MSPL, MODIS and the Microwave radar data showed that, the microphysical properties of liquid cloud could be retrieved by combining our MSPL and the inversion method.

Calibration of Underwater Polarization Image Based on the Radian of Distorted Curves in the Checkboard

Jiaming Wei,Qi Li,Lili Zhang 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.8

The calibration of polarization imaging system is the premise to obtain target polarization information accurately, in this paper, we propose a method of calibration based on the radian of distorted curves in the checkboard to solve the problem of losing polarization information in the underwater distorted polarization images. Firstly, we use the radian of distorted curves in the checkboard to calculate the coordinates of distortion center, and calibrate the region near the distortion center. Then we use the calibrated region to reconstruct the whole image. Finally, we combine the distorted image, the reconstructed image and the distortion model to obtain the calibration parameters. With these parameters we can get the calibrated polarization images. The experiments show that our method can calibrate the polarization image accurately, reduce the coupled error and calculate parameters independently.

High-speed cylindrical grinding of SiC: The process characteristics and surface integrity

Jiaming Ni 한양대학교 세라믹연구소 2013 Journal of Ceramic Processing Research Vol.14 No.1

In recent years SiC has emerged in industrial applications. However, due to its unique thermal and mechanical properties, economical machining always meets obstacles. In this study, high-speed grinding in conjunction with a high workpiece speed by a diamond grinding wheel is proposed as a solution. A rotating-4-component-dynamometer has been employed for the force measurements, followed by a series of tests on the surface quality including surface roughness, scanning electron microscope observations and residual stress analysis. It has been found that the combination of the elevated grinding wheel speed and the higher workpiece speed can lead to low grinding forces and thermal energy at almost all levels of the material removal rate in this study. Besides, the grinding-induced damage layer will be eliminated and the surface quality can be improved. With an elevated wheel speed, a brittle-ductile transition can be found based on the observation of the ground surface and the orientation of the surface roughness and the residual stresses. In view of the grinding energy analysis and surface quality tests, it can be concluded that high-speed grinding is an effective solution for the high quality and high efficiency cylindrical grinding of SiC.

Distinctive Judicial-Tailored Causation References of Construction Accidents

Jiaming Wang,Rui Cheng,Heap-Yih Chong,Pin-Chao Liao 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.8

Accident liability allocation is significant for social justice and industry safety. The allocation of liability between individuals and organizations depends on the judgment of their negligence in accidents. However, current judicial practice does not show a clear distinction between different accident types when allocating liabilities, and there is a lack of scientific evidence to guide the legal decision-making process in liability allocation. Unfortunately, current accident causation research does not sufficiently meet the requirements as scientific evidence to support the realization of more strategic and targeted liability allocation. This study introduces the qualitative comparative analysis (QCA) method into the field of accident analysis using crisp-set QCA (csQCA) to explore the causal distinctions between fall and non-fall accidents based on the human factor analysis and classification system (HFACS). The results show that organizational influence and unsafe acts distinctively signify fall and non-fall accidents, and that the precondition of unsafe acts is their junction. Theoretically, this study 1) furnishes a QCA tool that allows academic research with uncertainty to be used in the body of evidence that meets the requirements of law, thereby extending the application scope of accident research to the legal practice of liability allocation; and 2) provides meaningful references for the judgment of negligence and accident liability for judicial practice.

Re-investigation of the Mediating Effect of Brain Activities between Dispositional Factors and Hazard Recognition A Multilevel Logistic Regression Approach

Jiaming Wang,Yu-Sung Su,Pin-Chao Liao 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.9

Understanding the relationships among dispositional factors, brain activities, and hazard recognition is important for developing auxiliary safety technologies and improving construction safety performance. However, current logistic statistical models have embedded potential biases into the interpretation of brain activities. The purpose of this study was to re-investigate the mediation effect of brain activities between dispositional factors (risk propensity, work experience, and injury history) and hazard recognition performance (HRP). An experiment was designed in which 71 construction workers each completed 120 hazard recognition trials (N = 8520), while the research team used an electroencephalogram recorder to record the brainwaves of the participants. The data were analyzed by the multilevel logistic regression method, and the results showed that the brain activities in FP1, FP2, and AF3 significantly mediated the relationship between dispositional factors and HRP. The findings theoretically supplement the understanding of brain activities in different hazard cognitive stages for hazard recognition. The results should contribute to the development of neuro-engineering technology and safety management strategies.

Seismic Performance of Welded Steel Beam-to-Column Connections with Initial Weld Defects

Jiaming Li,Haoran Yu,Weibin Li,Weijia Cheng 한국강구조학회 2022 International Journal of Steel Structures Vol.22 No.2

Based on the research of steel structures destroyed in earthquakes, it is often found that brittle fractures of the bottom beam fl anges of welded beam-to-column connections are caused by welding defects. In this study, artifi cial surface notches in the welds of single beam fl anges were prepared, and four experimental specimens of welded steel beam-to-column connections were tested to explore the eff ects of the initial crack and three diff erent connection types on the seismic performance of the connections. Through extended fi nite element methods, the factor of the depth of the initial crack was discussed. The results showed that the fracture mode and the rate and location of crack propagation are signifi cantly changed, and the seismic performance of the connections is reduced when there is an initial crack existing in the weld of a single beam fl ange. The fracture in box beam to box column connections shows brittle failure regardless of the initial crack, but the depth of the initial crack has the least infl uence on their seismic performance among the three connection types. The seismic performance of H-shaped beam to H-shaped column connections is the most sensitive to the depth of the initial crack. It should be noted that the weld quality of steel beam-to-column connections, especially the connections with H-shaped columns, should be carefully checked and monitored during the welding construction process and after earthquakes to ensure the bearing and deformation capacities meeting the requirements.

Jiaming Zhu,Jingjing Liu,Xiaohuan Tang,Xiaofang Qiao,Chao Chen,Yuanda Liu 연세대학교의과대학 2019 Yonsei medical journal Vol.60 No.4

Colorectal cancer (CRC) is the second most common cause of cancer-related death worldwide, and its high rates of relapse andmetastasis are associated with a poor prognosis. Despite extensive research, the underlying regulatory mechanisms of CRC remainunclear. Long noncoding RNAs (lncRNAs) are a major type of noncoding RNAs that have received increasing attention inthe past few years, and studies have shown that they play a role in many biological processes in CRC. Here, we summarize recentstudies on lncRNAs associated with CRC and the signaling pathways and mechanisms underlying this association. We show thatdysregulated lncRNAs may be new prognostic and diagnostic biomarkers or therapeutic targets for clinical application. This reviewcontributes not only to our understanding of CRC, but also suggests novel signaling pathways associated with lncRNAs thatcan be targeted to block or eradicate CRC.
