Preliminary Study on the Vaporization Ratio of the Slurry in the Residue Fluid Catalytic Cracking Disengager

The vaporization ratios of the slurry at various temperature and partial pressure were calculated with the group-contribution method,and then the phase state of the slurry in the residue fluid catalytic cracking(RFCC) disengager was determined.This research could provide some advices on how to select the technological conditions to decrease the coking in the RFCC disengager.The oil gas temperature and the slurry partial pressure had signifi- cant effects on the vaporization ratio of the slurry.Increasing the oil gas temperature and reducing the slurry partial pressure could effectively slow down the coking speed in the RFCC disengager.According to the calculation results, a correlation was established to predict the vaporization ratio of the slurry under different operating conditions.

The Relationship between Internet Addiction and Cyberbullying Perpetration: A Moderated Mediation Model of Moral Disengagement and Internet Literacy

Internet addiction and cyberbullying have emerged as significant global mental health concerns in recent years.Although previous studies have shown a close association between Internet addiction and cyberbullying,the underlying mechanisms connecting these two phenomena remain unclear.Therefore,this study aimed to reveal the mechanisms involved between Internet addiction and cyberbullying perpetration from the perspective of cognition function.This study recruited 976 Chinese youth through online survey,using the short version of Internet Addiction Test(s-IAT),Chinese Cyberbullying Intervention Project Questionnaire(C-CIPQ),Cyberbullying Moral Disengagement Scale(CMDS),and Internet Literacy Questionnaire(ILQ)to investigate the relationship between Internet addiction,moral disengagement,Internet literacy and cyberbullying perpetration.The keyfindings of this study were as follows:after controlling gender and age,(1)Internet addiction had a significant positive predictive effect on cyberbullying perpetration;(2)moral disengagement acted as a mediator between Internet addiction and cyberbullying perpetration;and(3)Internet literacy played a moderating role between moral disengagement and cyberbullying perpetration.In conclusion,there was a moderated mediating effect between Internet addiction and cyberbullying perpetration,contributing to a better understanding of the relationship between these two phenomena.

Analysis of Autopilot Disengagements Occurring During Autonomous Vehicle Testing

In present-day highly-automated vehicles, there are occasions when the driving system disengages and the human driver is required to take-over. This is of great importance to a vehicle's safety and ride comfort. In the U.S state of California, the Autonomous Vehicle Testing Regulations require every manufacturer testing autonomous vehicles on public roads to submit an annual report summarizing the disengagements of the technology experienced during testing. On 1 January 2016,seven manufacturers submitted their first disengagement reports:Bosch, Delphi, Google, Nissan, Mercedes-Benz, Volkswagen, and Tesla Motors. This work analyses the data from these disengagement reports with the aim of gaining abetter understanding of the situations in which a driver is required to takeover, as this is potentially useful in improving the Society of Automotive Engineers(SAE) Level 2 and Level 3 automation technologies.Disengagement events from testing are classified into different groups based on attributes and the causes of disengagement are investigated and compared in detail. The mechanisms and time taken for take-over transition occurred in disengagements are studied. Finally, recommendations for OEMs, manufacturers, and government organizations are also discussed.

BUBBLE SIZES AND HOLDUP STRUCTURE IN BUBBLE COLUMNS DETERMINED BY DYNAMIC GAS DISENGAGEMENT

A new model for determining bubble size distributions in bubble columns by the dynamic gasdisengagement(DGD)technique is developed.It is based on an idea of non-uniform steady statedirstribution of bubble dispersion.Interpreting the axial non-uniformity,this model gives axial gasholdup distributions.If assuming an axially homogeneous dispersion,a radial gas holdup distributioncan be obtained.The Sauter mean diameters or specific interfacial areas for several systems areestimated by the technique.The results for an air-water system agree with those measured by afive-point conductivity probe technique.The obtained axial gas holdup distributions agree well withreported measurements and the radial gas holdup distributions are also reasonable.

How does an individual’s default behavior on an online peer-to-peer lending platform influence an observer’s default intention?

Previous studies indicate that individuals’default behaviors on online peer-to-peer(P2P)lending platforms greatly influence other borrowers’default intentions.However,the mechanism of this impact is not clear.Moreover,there is scarce research in regard to which factors influence the relationship between an individual’s default behavior and an observer’s default intention.These important questions are yet to be resolved;hence,we conducted two experiments using the scenario-based research method,focusing on Chinese online P2P lending platforms.Our results indicate that an individual’s default behavior can trigger an observer’s default intention as a result of the imperfect punitive measures as they currently exist on Chinese online P2P lending platforms.Both the observer’s moral disengagement level and pragmatic self-activation level serve as mediating variables.In situations where an observer knows an individual’s default behavior,the level of intimacy between the defaulter and observer positively affects the relationship between their default behavior and intention.The intimacy level also positively influences the relationship between the individual’s default behavior and the two mediator variables.Based on the findings,we provide management suggestions in the context of online P2P lending.Our study sets a foundation for future research to utilize other methods to extend the present research findings to other regions and domains.

Using eye movements in the dot-probe paradigm to investigate attention bias in illness anxiety disorder

BACKGROUND Illness anxiety disorder(IAD)is a common,distressing,and debilitating condition with the key feature being a persistent conviction of the possibility of having one or more serious or progressive physical disorders.Because eye movements are guided by visual-spatial attention,eye-tracking technology is a comparatively direct,continuous measure of attention direction and speed when stimuli are oriented.Researchers have tried to identify selective visual attention biases by tracking eye movements within dot-probe paradigms because dot-probe paradigm can distinguish these attentional biases more clearly.AIM To examine the association between IAD and biased processing of illness-related information.METHODS A case-control study design was used to record eye movements of individuals with IAD and healthy controls while participants viewed a set of pictures from four categories(illness-related,socially threatening,positive,and neutral images).Biases in initial orienting were assessed from the location of the initial shift in gaze,and biases in the maintenance of attention were assessed from the duration of gaze that was initially fixated on the picture per image category.RESULTS The eye movement of the participants in the IAD group was characterized by an avoidance bias in initial orienting to illness-related pictures.There was no evidence of individuals with IAD spending significantly more time viewing illness-related images compared with other images.Patients with IAD had an attention bias at the early stage and overall attentional avoidance.In addition,this study found that patients with significant anxiety symptoms showed attention bias in the late stages of attention processing.CONCLUSION Illness-related information processing biases appear to be a robust feature of IAD and may have an important role in explaining the etiology and maintenance of the disorder.

Clean air captures attention whereas pollution distracts:evidence from brain activities

Awareness of the adverse impact of air pollution on attention-related performance such as learning and driving is rapidly growing.However,there is still little known about the underlying neurocognitive mechanisms.Using an adapted dot-probe task paradigm and event-related potential(ERP)technique,we investigated how visual stimuli of air pollution influence the attentional allocation process.Participants were required to make responses to the onset of a target presented at the left or right visual field.The probable location of the target was forewarned by a cue(pollution or clean air images),appearing at either the target location(attention-holding trials)or the opposite location(attention-shifting trials).Behavioral measures showed that when cued by pollution images,subjects had higher response accuracy in attention-shifting trials.ERP analysis results revealed that after the cue onset,pollution images evoked lower N300 amplitudes,indicating less attentioncapturing effects of dirty air.After the target onset,pollution cues were correlated with the higher P300 amplitudes in attention-holding trials but lower amplitudes in attention-shifting trials.It indicates that after visual exposure to air pollution,people need more neurocognitive resources to maintain attention but less effort to shift attention away.The findings provide the first neuroscientific evidence for the distracting effect of air pollution.We conclude with several practical implications and suggest the ERP technique as a promising tool to understand human responses to environmental stressors.

Understanding the psychological aspects of the radicalisation process:a sociocognitive approach

Understanding the psychological dimensions underlying the radicalisation process is a con-siderable challenge in the context of the legal judicial treatment of perpetrators of acts of radical violence.This clinical and qualitative study is based on an analysis of legal expert interviews of people at different stages of the radicalisation process.It highlights common psychological characteristics in personality,mechanisms of moral neutralisation and socio-cognitive and interpretive treatment during radicalisation.These observations suggest the applicability of a model of cognitive-emotional transformation of self and meaning-building in radical violent engagement.
