We undertook a meta-analysis to explore the relationship between academic emotions (comprising positive high-arousal [PHA], positive low-arousal [PLA], negative high-arousal [NHA], and negative low-arousal [NLA] emotions) and academic performance among mainland Chinese students, and
analyzed the moderating effects of regional location, age, achievement domain match, and gender on these associations. Included in the research were 35 primary studies with 17,548 participants. Results of the meta-analysis showed overwhelming support for the positive correlations between PHA,
PLA, and academic achievement (rPHA = .312, rPLA = .376), and negative correlations between NHA, NLA, and academic achievement (rNHA = -.179, rNLA = -.371). Furthermore, moderation analyses suggested that these effects
were influenced by regional location, age, achievement domain match, and gender. Practical and theoretical implications of the findings are discussed.

We performed a meta-analysis of 79 studies to explore the relationship between positive and negative indicators of parenting style and Internet addiction among 44,650 mainland Chinese teenagers. Results showed that positive indicators of parenting style had a significant negative correlation
with teenagers' Internet addiction and that the correlation was moderated by region and school level. Negative indicators of parenting style were significantly and positively correlated with teenagers' Internet addiction and the correlation was also moderated by region and school level. Theoretical
and practical implications of the findings are discussed.

Most scholars have argued that student engagement positively predicts academic achievement, but some have challenged this view. We sought to resolve this debate by offering conclusive evidence through a meta-analysis of 69 independent studies (196,473 participants). The results revealed
that (a) there was a moderately strong and positive correlation between overall student engagement and academic achievement, and an analysis of the domains of behavioral, emotional, and cognitive engagement showed that almost all had a positive correlation with students' academic achievement;
and (b) a moderator analysis revealed that the relationship between student engagement and academic achievement was influenced by the method of reporting engagement, cultural value, and gender. Furthermore, the relationships of behavioral, emotional, and cognitive engagement with academic
achievement were influenced by reporting method for engagement, cultural value, or gender.

Water resources are critical for the survival and prosperity of both natural and socioeconomic systems. A good and informational water resources evaluation system is substantial in monitoring and maintaining sustainable use of water. The Driver-Pressure-State-Impact-Response (DPSIR) framework is a widely used general framework that enabled the measurement of water resources security in five different environmental and socioeconomic subsystems: driver, pressure, state, impact, and response. Methodologically, outcomes of water resources evaluation based on such framework and using fuzzy set pair analysis method and confidence interval rating method depend critically on a confidence threshold parameter which was often subjectively chosen in previous studies. In this work, we demonstrated that the subjectivity in the choice of this critical parameter can lead to contradicting conclusions about water resources security, and we addressed this caveat of subjectivity by proposing a simple modification in which we sample a range of thresholds and pool them to make more objective evaluations. We applied our modified method and used DPSIR framework to evaluate the regional water resource security in Jiangxi Province, China. The spatial-temporal analysis of water resources security level was carried out in the study area, despite the improvement in Pressure, Impact, and Response factors, the Driver factor is found to become less safe over the years. Significant variation of water security across cities are found notably in Pressure and Response factors. Furthermore, we assessed both cross-sectionally and longitudinally the inter-correlations among the DPSIR nodes in the DPSIR framework. The region-specific associations among the DPSIR nodes showed important deviances from the general DPSIR framework, and our analysis showed that in our study region, although Responses of regional government work effectively in improving Pressure and State security, more attention should be paid to improving Driver security in future regional water resources planning and management in Jiangxi Province, China.

AbstractExploring the relative importance of different routes in SARS‐CoV‐2 transmission is crucial in infection prevention. However, even in the same environmental setting, the relative importance of different routes has varied in different studies. We hypothesize that respiratory aerosol size and number distribution might play a key role. In this study, size and number distribution of respiratory droplets emitted from breathing, talking, and coughing were identified from PubMed and Web of Science. The infection risk of SARS‐CoV‐2 via airborne, droplet, and fomite transmission routes was modeled in a household and a healthcare setting. The relative importance of three routes varied with different size distributions in both settings. Generally, the contribution of the airborne route increased with the volume percentage of respirable droplets emitted. And the increase of the total number of emitted droplets leads to an increase in the contribution of tdroplet route. In the healthcare setting, as the total number of emitted droplets increased from 110 to 4,973, the contribution of droplet route increased from 62.24% to 98.11%. Next, by considering the combination of breathing, coughing, and talking when the infected person was asymptomatic, the airborne route predominated over the droplet and contact routes. When the infected person had developed symptoms, that is, cough, the droplet route played a dominant role in SARS‐CoV‐2 transmission. In conclusion, risk analyses will be improved with improved sampling methods that enable characterization of viruses within respiratory droplets of different sizes.

Mixed results from studies on Chinese cross-border mergers and acquisitions (M&As) have been a puzzle for both academia and business professionals over the years. Do these M&As create value when Chinese firms acquire foreign target firms suffering heavy losses and even on the verge of bankruptcy? This article explores the wealth effect of M&As conducted by Chinese firms as well as the relevant factors from the asset-seeking perspective. The authors use 180 M&A cases conducted by listed firms in China between 2002 and 2012 as samples and examine their wealth effects in a method of event study. The results show that these M&A activities have produced significant positive wealth effects during the event window of [-10, 10]. The authors then study the key factors affecting wealth effects. The findings reveal that an acquiring firm's strength via research and development (R&D) and M&A experience generates significant positive impacts on the wealth effect. The findings also reveal that an innovation orientation and development stage of host countries helps create positive wealth effects; vertical M&As are particularly favored by the market since they can gain easier access to R&D, marketing channels or mineral resources.
