The investigation of flow field can provide strong theoretical support for improving the flotation performance of fine particles in a cyclonic flotation column. In this study, particle image velocimetry (PIV) is combined with endoscopic measurement and phase discrimination technique to measure the cross section and axial section of gas–liquid two-phase flow field in a lab-scale cyclonic flotation column. The axial, radial, and tangential velocity of both gas and liquid phases are obtained. Based on the PIV experimental data, computational fluid dynamics (CFD)-based numerical models are validated. The results show the good prediction ability of Eulerian–Eulerian multiphase model, Reynolds stress model (RSM), and Tomiyama drag model. Then the simulated results with validated models are displayed to indicate the flow characteristics of the flotation column. The gas concentration is observed to be higher in the center and low on the sides. The gas phase always moves upward, while the liquid phase moves upward at the axis, downward between the axis and the wall, and upward again near the wall. Overall, this study provides an innovative approach for PIV measurement of complex multiphase flow field, and a useful reference for appropriate numerical models selection.

In the historical and cultural context of developing countries such as China, illegitimate tasks have become an important source of workplace pressure for employees. Guided by the framework of the stress-as-offense-to-self theory, effort–reward imbalance model, and dual-process work-home interference model, we explored how illegitimate tasks enhance turnover intention. A total of 474 employees from China effectively completed the online survey. The results showed a statistically positive correlation between illegitimate tasks, effort–reward imbalance, work–family conflict, and turnover intention. Illegitimate tasks can affect intention to quit directly and through two indirect paths: the separate intermediary effect of work–family conflict and the continuous mediating role of effort–reward imbalance and work–family conflict. The results indicated that illegitimate tasks enhance employees’ intention to quit through the role of effort–reward imbalance and work–family conflict. This study contributes to understanding the mechanisms underlying the relation between illegitimate tasks and workers’ turnover intention in the context of Chinese history and culture. Additionally, the findings have implications for reducing employees’ propensity to quit.

In order to explore the role of cognitive failure and anxiety between mobile phone addiction and learning burnout, 596 college students were surveyed with Anxiety scale, Cognitive Failure scale, Learning Burnout scale and Mobile Phone Addiction Tendency scale, which based on the latent moderated structural equation. The results show that: 1) The phone addiction has a positively significant effect on learning burnout; 2) The phone addiction can influence learning burnout through cognitive failure; 3) Anxiety can moderate the mediating role of cognitive failure.

Sexual objectification experience is that person experienced life with objectified information. In order to explore the influence of the sexual objectification experience on female college students’ selfie-posting behavior, 700 female college students were surveyed with the Interpersonal Sexual Objectification scale, Enjoyment of Sexualization scale, Social Network Selfile-posting scale and Imaginary Audience Ideation scale. The results show that: 1) Sexual objectification experience is significantly correlated with female college students’ selfie-posting behavior and enjoyment of sexualization. Female college students’ enjoyment of sexualization is significantly correlated with selfie-posting behavior. 2) Sexual objectification experience can predict female college students’ selfie-posting behavior through the partial mediating role of enjoyment of sexualization, and the mediating role of enjoyment of sexualization is moderated by female college students’ imaginary audience ideation. This research revealed the mechanism of the relationship between sexual objectification experience and selfie-posting behavior, which helps to guide female college students to actively and healthfully participate in social activities.

Emotional labor is characterized by two main regulation strategies: surface acting and deep acting. However, which strategy consumes more energy? To explore this, we used functional near-infrared spectroscopy (fNIRS) to measure changes in hemoglobin density while participants performed a task requiring them to make the opposite emotional facial expression of that presented in a picture. We found that (1) neither surface nor deep acting led to a significant change in hemoglobin concentration in the prefrontal cortex; (2) making negative and positive facial expressions activated the same left front and middle areas of the prefrontal cortex; and (3) making positive facial expressions activated the rear portion of the prefrontal cortex, but making negative facial expressions did not. Based on these findings and past work, we can infer that deep and surface acting may not significantly differ in terms of the activity in the prefrontal cortex energy consumed. Furthermore, engaging in positive and negative emotional labor appear to utilize some of the same neurological mechanisms, although they differ in others.

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin-speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four-dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non-fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.

The study explored how the dyads with different attachment styles behave towards Leary’s circumplex in coop- erative and competitive tasks. 100 strangers as a sample were surveyed through two experiments on computer, by using RBQ (Riverside Behavioral Q-sort) to examine their interpersonal traits through rated by experimenters. Relation Questionnaire (RQ) and ECR were also used to measure their attachment styles. There are three con- clusions based on the results of this study that: 1) Individuals of different attachment styles in interpersonal in- teraction had shown different trend of interpersonal styles; 2) Individuals of different attachment styles take up different area in interpersonal circumplex, which proves that it is continuous not discrete of interpersonal at- tachment style; 3) the dyads in different sex of different attachment types showed different satisfaction in these two tasks.

To test the same quality, but use different tests to compare, the first thing is equivalent. Many selections and exams are considering test inequality, so equal tests before comparison. In domestic, the research of test equating is seldom, and in these few studies only few models had been studied — Classical Test Theory and Item Response Theory. Among these test equating models include Rasch Model, this article will illustrate test equivalent and functions of different models in detail.

Correlation coefficients are dominant indexes of measurement instrument quality. Among the varieties of correlation coefficients Pearson product moment correlation coefficient is the most popular. That is why intraclass correlation attracts relatively less relation. But in certain conditions, Pearson product moment correlation coefficient is not effective and intraclass correlation takes advantage in stead. Intraclass correlation coefficient plays an important role in testing the quality of measurement instruments in behavior sciences, psychological measurement, behavioral genetics and medical sciences. In case of the constructs to measure is two or more aspects of the same concept, to test the reliability and the validity of the measurement intraclass correlation will exert its prevailing advantages. If correlation between unorder pairs groups of interest, Pearson product moment correlation will be of no sense in this case and intraclass correlation coefficient functions properly. Under the frame of ANOVA, three basic models of intraclass correlation are classified, as are models of one-way random effects, two-way random effects and two-way mixed-effect. This study will focus on the model of one-way random effects and its application in measurement instrument quality test.

Rasch model for solving the measurement of objectivity provides a feasible good solution, it causes abroad psychometric and other fields' scholars' wide attention. But so far the related research and exploration in domestic is very few. Rasch model is different from item response theory, it must conform to the model data collected a priory theory. Different data has different analysis method according to different criteria, it has different computing method when different conditions, for example, logit analysis, conditions logistic analysis, unconditional logistic analysis, etc. And Logistic regression model parameter estimation often uses maximum likelihood estimation method.

In this study we employed the Extended Parallel Process Model of risk communication to investigate the effectiveness of combining threat and efficacy messages to increase public engagement with climate change. A total of 515 Mandarin-speaking residents of Beijing, China were randomly assigned to view one of two climate change messages sourced from an online environmental website. The first message (high threat – low efficacy) described the negative impacts of climate change for China, but provided no information about what actions could be taken by citizens to reduce the threat. The second message (high threat – high efficacy) provided the same threat information, but also provided practical information on how to reduce the threat. Mediation analyses revealed that the high threat – high efficacy message elicited higher levels of perceived efficacy in viewers, which in turn predicted higher levels of danger control processing (intention to seek our more information and take action) and lower levels of fear control processing (message rejection and denial of threat). Moderation analyses revealed that the high efficacy messages were less effective for viewers with moderate to strong anthropocentric worldviews and very high ecocentric worldviews.
