Unlike some developed countries, Chinese food safety certification system is multi-level including organic/green/hazard-free certifications. The purpose of this paper is to assess consumers’ preferences for tomatoes carrying these different labels.

Data used in this study came from choice experiments (CEs) conducted in Shandong province, China. Based on experiment data, a random parameter logit model was established to analyze consumers’ willingness-to-pay (WTP).

Consumers’ WTP for organic tomatoes was higher than that for hazard-free and green-certified tomatoes. Furthermore, consumers’ WTP for the European Union (EU) organic label was higher than that for the Chinese organic label, whereas a non-significant difference existed between the levels of consumers’ WTP for hazard-free and green-certified tomatoes. Consumers with different food safety risk perception (FSRP) had large differences in WTP, whereas those with varying environmental awareness (ENAW) had similar levels of WTP.

This contribution is the first research which focuses on consumers’ WTP for EU organic label, Chinese organic label, green label, or hazard-free label on tomato through CEs in China. Furthermore, the influence of consumers’ FSRP and ENAW on their preference was analyzed through a random parameter logit model.

The purpose of this paper is to analyse the factors that influence food safety reporting intention and behaviour of the public.

Data used in this study came from a questionnaire survey conducted in Shandong Province, China. The 642 qualified samples were analysed through structural equation model based on the expanded theory of planned behaviour to study public food safety reporting behaviour and its influencing factors.

Results indicated that participation attitude, subjective norm, perceived behavioural control (PBC) and moral norm had significantly positive effects on public reporting intention, which had a direct effect on behaviour. Among subjective norm, descriptive norm had a more significant influence on the intention to report than injunctive norm. PBC indirectly affected reporting behaviour through participation intention, and directly affected participation behaviour. Socio-demographic variables had significant influence on participation attitude, injunctive norm and PBC, whereas these variables had no influence on descriptive norm and moral norm.

This research is of academic value and of value to policy makers. To promote public participation in food safety reporting, the government should consider influencing factors of food safety reporting.

Organic certification system became important means to restore consumer confidence in China. The purpose of this paper is to focus on consumer trust in organic milk of different brands and its influencing factors.

The data were collected from 876 randomly selected consumers in Shandong Province, China. And an ordered logistic model was established to analyze influencing factors of consumer trust.

Chinese consumers generally lack trust in organic milk. Consumer trust for different brands of organic milk was different, and was not high in general. Various factors, namely, age, education years, food safety awareness, evaluation of government regulation policy, evaluation of organic milk price, and purchase convenience, have a significant impact on consumer trust. Factors, such as income, environmental protection consciousness, and risk consciousness, are not significant.

This research is of academic value and of value to policy makers and suppliers. Government should promote institutional arrangement and strengthening supervision in production, certification, and circulation of organic products. Organic suppliers should implement reliable marketing strategy, such as correct pricing, and build a more extensive and convenient distribution network.

As retailers have increasingly embraced an omnichannel retailing strategy, explaining and predicting the helpfulness of online review should consider both online-based and offline-based reviews. The paper aims to discuss this issue.

Based on the signaling theory, this study intends to examine the impacts of review-related and reviewer-related signals on review helpfulness in the context of omnichannel retailing. The proposed research model and corresponding hypotheses were tested by using negative binomial regression.

The results shown that both review-related (review rating and review sentiment strength) and reviewer-related (reviewer real name and reviewer expertise) signals positively affect review helpfulness. Contrary to the authors’ expectations, review length negatively affects review helpfulness. Specifically, when the review submitted from an omnichannel retailer’s offline channel, the positive impacts of reviewer real name on review helpfulness will be stronger, and the positive impacts of reviewer expertise on review helpfulness will be weaker.

Unlike many previous studies tend to explore the antecedents of review helpfulness in a single-channel setting, the study examined the factors that affect review helpfulness in an omnichannel retailing context.

The purpose of this study is to examine the impact of social media affordances, specifically social engagement and social endorsement, on knowledge contribution in online Q&A communities. Building on self-determination theory, this research seeks to tackle the issue of under-provision of knowledge in these communities.

The study employs a sample collected from a popular social Q&A community in China and uses linear panel data models along with multiple robustness checks to test the research model.

The findings reveal that both social engagement and social endorsement have a positive effect on users' knowledge contribution to the online Q&A community. However, the impact of social engagement is mitigated by social endorsement.

This paper makes a valuable contribution to the field by filling the research gap on the role of social engagement behaviors and their interaction with social endorsement in online Q&A communities. The results provide insights into how social media affordances can be leveraged to enhance knowledge contribution in these communities.

This chapter investigates the effect of customer orientation and CRM organization on hotel financial performance. A model of enhancing hotel financial performance through customer satisfaction practices was tested. Customer satisfaction was hypothesized to be a mediator in the relationships between customer orientation and CRM organization and the result being financial performance. The sample consisted of 54 hotels that was made up of three 5-star, fifteen 4-star, and thirty-six 3-star hotels in Ghana. A quantitative deductive approach was employed to gather data using cross-sectional survey, which was analyzed using PLS-SEM to check the validity, reliability and factor loading of the data. The findings revealed that, CRM organization enhances customer satisfaction and financial performance of hotels. Also, customer orientation showed significant positively related to customer satisfaction in the hotels. Surprisingly, the effects of CRM organization and customer orientation on financial performance through customer satisfaction were insignificant. Thus, customer satisfaction failed to mediate the effect of CRM organization and customer orientation on the financial performance of hotels. This suggests that though an effective CRM organization enhances customer satisfaction, it directly affects the financial performance of hotels. The outcomes have useful implications for CRM implementation on hotel financial performance in Ghana.

Proper platform pose is important for the mobile manipulator to accomplish dexterous manipulation tasks efficiently and safely, and the evaluation criterion to qualify manipulation performance is critical to support the pose decision process. This paper aims to present a comprehensive index to evaluate the manipulator’s operation performance from various aspects.

In this research, a criterion called hybrid manipulability (HM) is proposed to assess the performance of the manipulator’s operation, considering crucial factors such as joint limits, obstacle avoidance and stability. The determination of the optimal platform pose is achieved by selecting the pose that maximizes the HM within the feasible inverse reachability map associated with the target object.

A self-built mobile manipulator is adopted as the experimental platform, and the feasibility of the proposed method is experimentally verified in the context of object-grasping tasks both in simulation and practice.

The proposed HM extends upon the conventional notion of manipulability by incorporating additional factors, including the manipulator’s joint limits, the obstacle avoidance situation during the operation and the manipulation stability when grasping the target object. The manipulator can achieve enhanced stability during grasping when positioned in the pose determined by the HM.

The main cause of aseptic inflammation after an in vivo implantation is that Poly(L-lactide) (PLLA) and Poly(D-lactide) have a slower degradation and absorption rate, while Poly(D, L-lactide) (PDLLA) has a much faster degradation rate than PLLA because of its amorphous structure. Also, the hydrolyzate of Hydroxyapatite (HA) is alkaline, which can neutralize local tissue peracid caused by hydrolysis of Polylactic acid.

In this study, the selective laser sintering (SLS) technique was chosen to prepare bone scaffolds using nano-HA/PDLLA composite microspheres, which were prepared by the solid-in-oil-in-water (S/O/W) method. First, the SLS parameters range of bulk was determined by the result of a single-layer experiment and the optimized parameters were then obtained by the orthogonal experiment. The tensile property, hydrophobicity, biocompatibility, biological toxicity and in vitro degradation of the samples with optimized SLS parameters were characterized.

As a result, the samples showed a lower tensile strength because of the many holes in their interior, which was conducive to better cell adhesion and nutrient transport. In addition, the samples retained their inherent properties after SLS and the hydrophobicity was improved after adding nano-HA because of the OH group. Furthermore, the samples showed good biocompatibility with the large number of cells adhering to the material through pseudopods and there was no significant difference between the pure PDLLA and 10% HA/PDLLA in terms of biological toxicity. Finally, the degradation rate of the composites could be tailored by the amount of nano-HA.

This study combined the S/O/W and SLS technique and provides a theoretical future basis for the preparation of drug-loaded microsphere scaffolds through SLS using HA/PDLLA composites.

The study investigates service quality in developing customer loyalty in Ghana’s auto detailing industry. The study also examines how customer satisfaction and service innovation indirectly and positively influence the relationship between service quality and customer loyalty.

A sample of 318 respondents, drawn from a convenience sampling method, was utilised for the analysis. Partial Least Squares (PLS) of Structural Equation Modelling (SEM) technique was used to analyse the data to obtain results.

The study established a significant positive relationship between the tangibility dimension of service quality and customer loyalty; however, this influence is indirect through the mediation effect of customer satisfaction between service innovation and customer loyalty.

The study provides a useful guide for policy formulation and implementation by managers of auto detailing services to enhance customer loyalty as a basis of sustainable business performance.

The study is the first of its kind to investigate the role of service quality and customer loyalty being mediated by service innovation and customer satisfaction in the context of Ghana’s auto detailing industry.

In the implementation of large-size additive manufacturing (AM), the large printing area can be established by using the tiled and fixed multiple printing heads or the single dynamic printing head moving in the x–y plane, which requires a layer decomposition after the mesh slicing to generate segmented infill areas. The data processing flow of these schemes is redundant and inefficient to some extent, especially for the processing of complex stereolithograph (STL) models. It is of great importance in improving the overall efficiency of large-size AM technics software by simplifying the redundant steps. This paper aims to address these issues.

In this paper, a method of directly generating segmented layered infill areas is proposed for AM. Initially, a vertices–mesh hybrid representation of STL models is constructed based on a divide-and-conquer strategy. Then, a trimming–mapping procedure is performed on sliced contours acquired from partial surfaces. Finally, to link trimmed open contours and inside-signal square corners as segmented infill areas, a region-based open contour closing algorithm is carried out in virtue of the developed data structures.

In virtue of the proposed approach, the segmented layered infill areas can be directly generated from STL models. Experimental results indicate that the approach brings us the good property of efficiency, especially for complex STL models.

The proposed approach can generate segmented layered infill areas efficiently in some cases.

The region-based layered infill area generation approach discussed here will be a supplement to current data process technologies in large-size AM, which is very suitable for parallel processing and enables us to improve the efficiency of large-size AM technics software.
