This paper aims to discuss the dynamic adsorption processes of carbon dioxide in a porous fixed bed on the industrial scale, using a multiple-relaxation-time lattice Boltzmann (LB) model.

A multiple-relaxation-time LB model is developed to predict the dynamic adsorption processes of carbon dioxide in a porous fixed bed on the industrial scale. The breakthrough curves from the simulation results are compared with the experimental data to validate the reliability of this model, and the effects of flow velocity, porosity and linear driving force mass transfer coefficient on the adsorption behaviors of carbon dioxide are explored further.

The numerical results show that the improved fluid flux leads to the reduction in the time required for completion of adsorption processes nonlinearly, and the differential pressure significantly raises with the decreasing porosity of porous fixed bed for fixed values of Reynolds number and total adsorption capacity. The maximum adsorption ratio of carbon dioxide was found at Re = 12 in this work. In addition, the higher mass transfer resistance of adsorbent particles advances the appearance time of the breakthrough point and delays the completion time of the adsorption processes.

This work will provide a way to study the adsorption technology of carbon dioxide in the fixed-bed using the LB method.

Beneficiary photos on charity appeals are believed to engender prosocial behavior. This study explores photo framing of healthy and unhealthy beneficiary photos in the context of photo-rich online medical crowdfunding. Based on framing theory, emphasis framing effect (i.e. unhealthy photos only vs both healthy and unhealthy photos) and equivalency framing effect (i.e. healthy photos prior to unhealthy photos vs unhealthy photos prior to healthy photos) are identified.

A scenario-based experiment with 135 participants was used to empirically test the proposed research hypotheses. The subjects were randomly assigned to three treatment groups, with 45 subjects in each group. ANOVA, linear regression, and multiple mediation analysis were used to analysis data.

The results reveal that disclosing both healthy and unhealthy photos can elicit stronger sympathy and perceived need than merely disclosing unhealthy photos. Moreover, the order of unhealthy photos prior to healthy photos leads to a higher level of sympathy than the order of healthy photos prior to unhealthy photos. Furthermore, sympathy and perceived need are positively related to donation intention.

First, this study extends the photo-related research limited to certain characteristics of a single photo to the sequence effect of multiple photos. Second, this study contributes to framing theory by introducing photo framing, particularly the equivalence and emphasis framing effect of beneficiary photos. Finally, this study reveals the emotional and cognitive routes through which beneficiary photos stimulate prosocial behavior. It also offers practical guidance in the aspects of the framing effect of beneficiary photos for crowdfunding management.

Information asymmetry is an inevitable issue in e-commerce and largely hampers the development of online shopping. The purpose of this paper is to propose a model to investigate the emotional content of online customer reviews, which are considered an efficient way to reduce information asymmetry, as a potential signal of product quality. The moderating effects of perceived empathy and cognitive effort are also explored on the basis of signaling theory.

A laboratory experiment with 120 subjects was used to empirically test the proposed research hypotheses. The subjects were randomly assigned to two treatment groups, with 60 subjects in each group. ANOVA, linear regression and binary logistic regression were used.

The emotional content of online customer reviews positively influences perceived product quality, which subsequently and positively affects purchase decisions. The emotional content of online customer reviews greatly influences perceived product quality when perceived empathy or cognitive effort is high.

This study is the first to extend extrinsic cues to emotional content on the basis of signaling theory and reveals the important role of emotional content of reviews. Moreover, the mediating effect of perceived product quality and the moderating effect of perceived empathy and cognitive effort illustrate the mechanism of the influence of emotional content on purchase decision. Findings demonstrate the positive signal of emotional content and provide important practical implications for sellers and customers.

Government social media profiles (GSPs) are increasingly used by government agencies during social crises, and the success of GSPs is highly dependent on netizens’ participation behavior (NPB). Drawing upon the social support theory, the purpose of this paper is to propose a theoretical model to examine the determinants and outcomes of NPB during a social crisis.

To test the research model, a field survey was conducted in the context of Tianjin 2015 explosions in China. The authors adopted a two-step approach to test the models. First, the authors conducted exploratory factor analysis to evaluate the measurement properties of the reflective latent constructs. Then, the authors performed a structural equation analysis to test the hypotheses.

The results show that information support and emotional support are significant determinants of NPB and persona involvement moderates the relationships between them. Additionally, this study reveals that information source preference and increasing enthusiasm for becoming a civil journalist are two critical and significant outcomes of NPB.

There are some limitations in this paper that must be taken into account when interpreting its findings. First, the study is designed on a single profile and concerns a single social crisis. Additionally, future research might consider incorporating factors beyond the individual level, e.g., community social capital (Putnam, 1993). Finally, with the emergence of various IT platforms, such as a government’s own website and online forms, future research can investigate how their characteristics can facilitate other social media platforms’ participation.

This paper offers a number of crucial research implications to the literature of social media in crisis management, thereby contributing to the explanation of NPB on GSPs in the management of social crises. Considering social support as a factor affecting NPB on GSPs, the authors also add personal involvement to the research on the functions of NPB on GSPs and include encouraging civil journalist and making GSPs the principal source of political information.

The research provides participating netizens on GSPs with some suggestions about generating more cost-effective and useful interventions to improve netizen participation levels on GSPs. The findings highlight that governmental social media profiles must focus on continuous development, such as trying best to satisfy the habits of netizens, to motivate netizens to create dependence of information acquisition on the GSPs, called information source preference. On the other hand, the study reminds netizens of the importance of NPB on GSPs during crises and encourages them to act as civil journalist.

First, the study investigated the outcome effect of NPB on GSPs on netizens’ information source preference and civil journalist. Second, this study identifies the determinants of NBPs on GSPs from both the informational and the emotional support perspectives. Third, this study investigates the moderating effects of personal involvement on the relationships between determinants from social support and NPB on GSPs.

Drawn from the social playfulness literature and the elaboration likelihood model, the purpose of this paper is to propose and test a research model to examine users’ continuous participation in SNS game applications.

A field survey with 133 subjects was conducted to test the research model.

Two identified design features, symbolic physicality and inherent sociability, are found to influence users’ perceived curiosity and perceived enjoyment toward playing SNS game applications. Perceived enjoyment is significantly associated with perceived curiosity and predicts users’ continuous participation of SNS game applications. The authors also observed a gender difference of social playfulness design on perceived curiosity.

Use intention was used as a proxy for actual use behavior, since objective data on continuance behavior was not available. Additionally, the contributions of this study may be constrained by one single sample.

The findings of the study suggest practical guidelines for designing game applications in SNS through socialization design and symbolic physicality. Further, based on the findings of gender differences, a personalization game design strategy is provided.

The study contributes to the post-adoption IS literature and sheds light on the interesting area of social media participation. Additionally, this study enriches the online gaming research by demonstrating gender differences.

Based on the literature on information security (InfoSec) education and uses and gratifications theory, the purpose of this paper is to propose and test a research model to examine the impact of InfoSec education on social media usage.

The authors employed structural equation modeling to test the research model, with a survey data set of 293 valid subjects from a WeChat subscription about InfoSec education named secrecy view.

The results reveal the significant impacts of perceived content quality, perceived social influence and perceived entertainment on user satisfaction in the context of security education and social media. User satisfaction is significantly associated with user stickiness and security knowledge improvement. Additionally, the authors found that user’s security awareness moderated the effect of perceived entertainment on user satisfaction.

Using a single sample might constrain the contributions of this study.

The authors suggest practical guidelines for InfoSec education on social media by enhancing perceived content quality. Moreover, due to diverse user attributes, the social media operators should recommend targeted content to different users.

This study contributes to studies on InfoSec education of social media usage and identifies factors that affect user satisfaction with social media. Furthermore, the study enriches the security education practices by uncovering differences in security awareness with regard to user satisfaction.

Based on government data from 1993 to 2008, this chapter aims to compute and analyze the trends of inequity in interprovincial and regional per-student spending in China's compulsory education, and to ascertain the potential impact of changes in education financing policies. Appropriate inequity measures (Gini and Theil index and Gini decomposition, among others) are employed to provide a systematic picture of the trends. Main findings include: (1) all inequity measures show large and overall increased disparities among provinces and among regions, between 1993 and 2008. (2) However, a slight drop of spending inequity is observed at the primary education level around 2002 and a larger reduction in 2005 and on. There are more turning points in the trend of lower-secondary per-student spending among provinces. These patterns are consistent across different inequity measures and spending indicators (per-student total spending, per-student recurrent spending, and per-student nonpersonnel spending). (3) The trend toward more balanced resource allocation around 2002 and 2005 could be the impact from the Reform of Tax and Administrative Charges and the New Mechanism for Financing Rural Compulsory Education. An increased share of budgetary expenditure in determining total spending suggests that equalizing financing policies have the potential to induce a significant reduction in spending inequity. These findings may help policy makers to better understand and alter the extent of spending inequity in compulsory education. This is an original empirical study that systematically derives the spending inequity trends over a long period in China's compulsory education.

The confirmation of receipt of orders by consumers means that the online retailer actually receives the payments on many retail platforms (e.g. Taobao). In order to recoup funds as soon as possible, the retailer will take steps (e.g. improving the level of delivery and adopting a rebate policy) to encourage consumers to confirm receipt earlier. It is significant for the retailer to identify an appropriate strategy and determine the optimal product price. To address the above issues, this paper examines and compares the pricing strategies and profits under different strategies to show some managerial insights for the retailer's decision-making.

In this paper, the authors discuss four models, i.e. adopting common delivery and offering consumers no rebates, adopting common delivery and offering rebates, adopting fast delivery and offering no rebates and adopting fast delivery and offering rebates, which the retailer may consider. Under different models, consumer utility and firm's profit structure are disparate. After comparing the retailer's profits under four models, the optimal strategy, profit and product price are obtained.

Some interesting results are as follows. When the cost of fast delivery is not very high, improving the level of delivery would bring more profit to the retailer and create a positive impact on consumers. Interestingly, our results also show that offering proper rebates to stimulate consumers to confirm receipt early only serves to improve the profit only when the motivation of consumers to confirm the receipt is very low. Moreover, the authors find that a higher level of delivery services can promote the implementation of the rebate policy to improve the retailer's earnings.

This paper is the first study on the transaction mode of retail platforms and the problem of confirming receipt by a model-based method.
