AbstractThe present study investigated 3‐ to 6‐year‐old (total n = 158) children's restoration behaviors both when they were second‐party victims (Experiment 1) and when they were third‐party bystanders (Experiment 2) of transgressions. We also explored how group membership (based on color preference) affects these behaviors. We found that children preferred restoration to punishment, and that they emphasized restorative justice not only for themselves, but also for others. Furthermore, when they were victims of transgressions, the tendency to choose restoration over punishment was stronger in older than younger children. Second‐party restoration behavior was influenced by group concerns in that children treated in‐group transgressors more leniently than out‐group and unaffiliated transgressors, but third‐party restoration behavior was not. Our research challenges the view that punishment is the standard response to transgressions and suggests that alternative options like restoration are sometimes preferred over punishment by young children.

AbstractPrevious research shows that the recipient's verbal communication about desires increases young children's sharing behavior. The current study examined how an adult partner's non‐verbal communication through eye gaze influenced sharing behavior in children from different cultures. We presented one hundred forty‐six 3‐ to 5‐year‐old American and Chinese children with a Dictator Game, in which they were asked to distribute resources between themselves and an experimenter. Children were randomly assigned to three conditions, in which the experimenter alternated her gaze between the child and the items that she wanted, or looked randomly around the room, or left when the child made decisions about sharing but claimed to come back later. Results showed that Chinese children shared more than American children did in the alternating‐gaze condition, but not in the other two conditions; furthermore, the experimenter's alternating gaze influenced Chinese children to be more generous, but had no significant effect on American children. This suggests that compared to American children, Chinese children may be more compliant with others' requests communicated through a subtle cue of eye gaze. The study demonstrates important differences in sharing behaviors between American and Chinese preschoolers, and these differences are consistent with the cultural constructs of individualism and collectivism.

PurposeThis paper aims to examine a subset of survey data collected through the Computing Research Association's Graduate Cohort Program to see how well theoretical and empirical factors fit with the actual motivations of women graduate students from different cultural backgrounds.Design/methodology/approachSurvey responses from international and US women participants in a support program for CSE graduate women in the USA are compared.FindingsThese analyses indicate that US and international women are similar in what drew them to graduate computing programs. It was chiefly their interest in and enjoyment of computing. They differ in the attraction of particular career features, influence of peers, and belief in the value of competition among graduate students.Research limitations/implicationsThis study is limited by the extent to which these data permit thorough testing of theoretical models, and by lack of comparison with men in computing or women who chose not to enter a graduate computing program.Practical implicationsThe similarities and differences between international and US women in CSE suggest ways to improve the gender balance in this field.Originality/valueThis study provides unique insight into an understudied population.

AbstractThis research focused on the relationships among 34 major airports in China, analyzing how these relationships are influenced by spatial dependence and heterogeneity. Using a spatial econometric model, it found that passenger traffic in China's airports displays a mutually driven aggregation effect. Furthermore, the study revealed that the airport relationship changes from complementarity to competition as the geographic distance between them decreases. The study also classified the main airports in China into three hierarchical levels and found significant complementarity and competition among those within the hub-and-spoke network structure. Specifically, this study identified a complementary relationship among regional trunk and local branch airports, as-well-as significant competition among hub airports. Crucially, the study suggests that the absence of a hub airport weakens the collaborative interactions between different types of airports, emphasizing the critical importance of hub airports for the connectivity and operational efficiency of China's airport network.

AbstractDisparities in socioeconomic status (SES) may affect individuals' risk preferences, which have important developmental consequences across the lifespan. Yet, previous research has shown inconsistent associations between SES and risky decision‐making, and little is known about how this link develops from a young age. The current research is among the first to examine how SES influences preschoolers' risky decisions in both gain and loss frames. Across two studies, children aged 5 to 6 years (total N = 309, 154 boys) were asked to choose between certain and risky options. The risky option was more advantageous, equal to, or less advantageous than the certain option. Study 1 revealed that in the loss frame, high‐SES children (n = 84, 44 boys) chose more risky options and were more sensitive to the expected value compared to low‐SES children (n = 78, 42 boys), especially when the risk was more advantageous. However, this SES difference was not significant in the gain frame. Supporting the potential causal link between SES and risky decision‐making, Study 2 further found that experimentally increasing low‐SES children's (n = 68, 30 boys) status by providing additional resources increased their risk‐seeking behavior in the loss frame. Overall, our findings suggest an interaction between environmental cues (gain vs. loss) and early life circumstances (SES) in shaping children's risk preferences.Research Highlights
This research is among the first to examine how school backgrounds and experimentally manipulated SES influence preschoolers' risk preferences in gain and loss frames.
Children were more risk‐seeking for losses than for gains; this framing effect was stronger in higher‐SES than lower‐SES children.
Lower‐SES children exhibited fewer risk‐seeking behaviors and decreased sensitivity to the expected value of options for losses, but not for gains.
A temporary boost in SES increased children's risk‐seeking behavior, but not sensitivity to expected values.

AbstractLow removal rate for total nitrogen (TN) is the main limitation of a membrane bioreactor (MBR). The effects of intermittent aeration on the removal of TN and the microbial community structure of activated sludge from a submerged membrane bioreactor (SMBR) operating at three different aeration on/off times (run 1, continuous aeration; run 2, 60/60 min aeration on/off time; and run 3, 60/75 min aeration on/off time) were studied. The results showed that the removal rates for TN under different operation conditions were 26.2% (run 1), 59.5% (run 2) and 70.7% (run 3), respectively, and significant improvements were achieved. Monounsaturated phospholipid fatty acids (PLFAs) and saturated PLFAs were dominant PLFA types in activated sludge, followed by branched PLFAs; cyclopropane fatty acid were relatively small in amount. The highest ratio of the characteristic fatty acid representing the abundance of bacteria in activated sludge was found in run 2. Aerobic prokaryotes were the predominant groups under all three operation conditions, followed by the anaerobic bacteria and the Gram‐positive bacteria group; sulphate‐reducing bacteria (SRB) and other anaerobic bacteria occupied the lowest proportion. Intermittent aeration can be used as a possible means to improve the treatment performance in an MBR.
