This study aims to evaluate the thermal performance of sodium alginate (SA) aerogel attached to nano SiO₂ and its radiative cooling effect on firefighting clothing without environmental pollution.

SA/SiO₂ aerogel with refractory heat insulation and enhanced radiative cooling performance was fabricated by freeze-drying method, which can be used in firefighting clothing. The microstructure, chemical composition, thermal stability, and thermal emissivity were analyzed using Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analyzer and infrared emissivity measurement instrument. The radiative cooling effect of aerogel was studied using thermal infrared imager and thermocouple.

When the addition of SiO₂ is 25% of SA, the prepared aerogel has excellent heat insulation and a high radiative cooling effect. Under a clear sky, the temperature of SA/SiO₂ aerogel is 9.4°C lower than that of pure SA aerogel and 22.1°C lower than that of the simulated environment. In addition, aerogel has more exceptional heat insulation effect than other common fabrics in the heat insulation performance test.

SA/SiO₂ aerogel has passive radiative cooling function, which can efficaciously economize global energy, and it is paramount to environment-friendly cooling.

This method could pave the way for high-performance cooling materials designed for firefighting clothing to keep maintain the wearing comfort of firefighters.

SA/SiO₂ aerogel used in firefighting clothing can release heat to the low-temperature outer space in the form of thermal radiation to achieve its own cooling purpose, without additional energy supply.

The objective of this study is to examine the effect of human model facial presentation (a smiling facial expression vs a neutral facial expression vs no facial presentation) on consumers' approach behavior and to determine the mechanism and boundary conditions behind such effects.

The research consisted of four laboratory experiments.

The results of four studies showed that a smiling facial expression led to the highest score for approach behavior. Pleasure and arousal mediated the effect of facial presentation on approach behavior. In the relationship between facial presentation and approach behavior, the moderating effects of emotional receptivity and the situation were significant. To be specific, for participants with high emotional receptivity, smiling facial expressions led to the highest approach behavior; for participants with low emotional receptivity, neutral expressions led to the highest approach behavior. In a browsing situation, the approach behavior of participants in response to a smiling facial expression was the highest. However, no significant differences were found in approach behavior under the three conditions regarding a purchasing situation.

This study supplements the literature on human model presentation and enriches the study of facial expressions.

Modern construction projects are increasingly complex and rely heavily on multi-discipline collaboration, and this leads to a more and more decentralized project-based structure widely adopted in the construction industry. While job satisfaction (JS) and job performance (JP) have been heavily studied previously, few considered the impact of organizational structure and none investigated the relationship between the organizational decentralization degree with JS and JP. This research aims to fill this research gap and investigate the impacts of organizational decentralization degree on JS and JP and facilitate a better project management practice for large-scale construction projects.

This research firstly establishes four hypotheses based on the literature review on general project-based organizations, then the hypotheses are tested by a survey covering 25 large complex construction projects in China. A hierarchical linear model analysis was carried out to analyze the survey data and to study the relationships between organizational decentralization degree, job satisfaction and job performance.

Analysis results show that projects' employees' JS and JP are positively correlated with the construction project organizations' decentralization degree, respectively. The decentralization degree has a higher impact on JS than on JP. Employees' JP is positively correlated with their JS, and a higher decentralization degree leads to a more significant positive impact that JS puts on JP.

The findings are new evidence of how construction organization structure and its decentralization degree can affect project employees' JS and JP. This research provides valuable guidance for the industry's management practice and is particularly important for large, complex and highly decentralized construction projects.

Drawing on recent literature and empirical data, the purpose of this paper is to explore the relationships between perceived organizational support (POS), perceived overqualification (POQ) and turnover intentions (TI) in repatriates working in multinational corporations (MNCs).

Survey data were collected from 145 repatriates who had been contacted beforehand from MNCs in China. Structural equation modeling and hierarchical regression are used to examine the data.

It is shown that POQ and POS both affect repatriates TI, with POQ having the stronger effect, while POS plays a mediatory role between POQ and TI. Specifically, under the same POQ, repatriates TI will decrease as the POS increases.

The study design is cross-sectional and based on self-reporting, which makes causal explanations of the results difficult.

POQ and POS are both shown to influence TI, with POQ having the greater effect. This means managers can offset the effect of repatriates POQ on TI by providing better support and assistance, which can help MNCs reduce repatriates TI and retain employees.

This paper examines the antecedents of TI, and adds valuable new insights to the literature on repatriation through its research data, offering further evidence that managers in transnational corporations should pay more attention to organizational support policy on repatriates in order to reduce their turnover.

The purpose of this paper is to identify key countries and their focal research fields on the information divide.

Literature was retrieved to identify key countries and their primary focus. The literature research method was adopted to identify aspects of the primary focus in each key country.

The key countries with literature on the information divide are the USA, China, the UK and India. The problem of health is prominent in the USA, and solutions include providing information, distinguishing users’ profiles and improving eHealth literacy. Economic and political factors led to the urban–rural information divide in China, and policy is the most powerful solution. Under the influence of humanism, research on the information divide in the UK focuses on all age groups, and solutions differ according to age. Deep-rooted patriarchal concepts and traditional marriage customs make the gender information divide prominent in India, and increasing women’s information consciousness is a feasible way to reduce this divide.

This paper is an extensive review study on the information divide, which clarifies the key countries and their focal fields in research on this topic. More important, the paper innovatively analyzes and summarizes existing literature from a country perspective.

This paper aims to explore the moderation effect of person-organization fit and perceived career and repatriation support on the relationship between knowledge governance and knowledge transfer intention of repatriates at multinational corporations.

Survey data were collected from 243 repatriates who had been contacted beforehand from MNCs in China. Hierarchical regression, AMOS, and PROCESS tools were used to examine the data.

The results revealed that the repatriate knowledge governance mechanism was positively related to repatriate knowledge transfer intentions. What's more, person-organization fit and perceived career and repatriation support significantly moderate the effect of knowledge governance mechanisms on repatriate knowledge transfer intention.

This is the initial empirical research on the influence of person-organization fit and perceived career and repatriation support on the relationship between knowledge governance and repatriate knowledge transfer; it may help readers understand the complex process and relationships associated with repatriate knowledge transfer, and the results may be useful for repatriate knowledge governance in multinational corporations.

China’s globalizing Internet describes a situation where China is using the Internet as a tool or medium to transmit its voice on the world stage and enhance its influence over the global Internet governance system and the global digitalization process. Several concerns, however, exist regarding China’s globalizing Internet strategies. This paper aims to respond to these concerns and enhance the understanding of China’s globalizing Internet strategies.

This paper will use content analysis to trace the policy development trajectory of China’s globalizing Internet, including policy vision, policy-making agencies and policy tools.

The Chinese government has issued a considerable number of policies to regulate and promote the development of the Internet since 2014. The key trend that emerged from the analysis of China’s globalizing Internet policy is the cooperation among different agencies. Existing policies have comprehensively used the supply-oriented tools, the environment-oriented tools and the demand-oriented tools; and the last two tools have been used more frequently in recent years.

The analysis results contribute to understanding how China uses digital technology to enhance its influence over the global Internet governance system.

Flights are often delayed owing to emergencies. This paper proposes a cooperative slot secondary assignment (CSSA) model based on a collaborative decision-making (CDM) mechanism, and the operation mode of flight waves designs an improved intelligent algorithm to solve the optimal flight plan and minimize the total delay of passenger time.

Taking passenger delays, transfer delays and flight cancellation delays into account comprehensively, the total delay time is minimized as the objective function. The model is verified by a linear solver and compared with the first come first service (FCFS) method to prove the effectiveness of the method. An improved adaptive partheno-genetic algorithm (IAPGA) using hierarchical serial number coding was designed, combining elite and roulette strategies to find pareto solutions.

Comparing and analyzing the experimental results of various scale examples, the optimization model in this paper is greatly optimized compared to the FCFS method in terms of total delay time, and the IAPGA algorithm is better than the algorithm before in terms of solution performance and solution set quality.

Based on the actual situation, this paper considers the operation mode of flight waves. In addition, the flight plan solved by the model can be guaranteed in terms of feasibility and effectiveness, which can provide airlines with reasonable decision-making opinions when reassigning slot resources.

With the development of the sharing economy, the collaborative consumption model has become more popular and has changed the way people engage in tourism. This study aims to explore. consumer experience in different types of rooms on a shared accommodation platform.

In this study, the authors divided the rooms on the shared accommodation platform into a budget type and a luxury type according to the room price and used content analysis to analyze 15,710 online reviews published on Xiaozhu.

This study found that consumer expectations varied depending on the room type. “Host,” “room,” “transportation and location” and “value” were the four common topics that consumers paid attention to in both room types. “Environment” and “objective conditions” were the particular focuses of the budget room consumers. However, consumers cared about “aesthetics” and “accommodation purpose” when staying in luxury rooms. These results reflected the influence of room prices on consumer experiences.

To the best of the authors’ knowledge, this study is one of the first to compare the consumer experience in rooms at different price points based on the evidence provided in online reviews. Latent Dirichlet allocation (LDA) analysis was used to extract the underlying topics from the online reviews, which provided more exciting results. This study leads to a comprehensive understanding of the consumer experience from the perspective of expectation theory, enriching the prior research on shared accommodation platforms.

This paper aims to examine whether chief executive officer’s (CEO) information technology (IT) background can affect enterprises’ continuous green innovation (CGI).

This study uses the data of China’s listed enterprises from 2011 to 2019.

The statistical results reveal that when a company hires a CEO with an IT background, its CGI can be higher. Firm ownership, firm digitization and industry bias alter the impact of CEO’s IT background on firms’ CGI. This effect is most pronounced in non-state-owned enterprises (non-SOEs), high-digitalized enterprises and skill-biased industries, while not in SOEs, low-digitalized enterprises and labor-biased industries.

This study has practical implications, as it measures CGI of enterprises. It also points to the necessity for a CEO’s IT background to enhance CGI.

The findings provide new strategies for incentivizing sustainable development and green innovation.

To the best of the authors’ knowledge, this study is the first to discuss the association between CEO’s IT background and enterprises’ CGI. The conclusions enrich both upper echelons theory and enterprise green innovation literature.
