The current study intended to better understand how peer alienation might influence adolescents' cyber flaming, cyber pornography and cyber deception, and examine their mechanisms: The mediating role of core self-evaluation and the moderating role of father-child relationship, mother-child relationship and gender. This model was examined with 644 Chinese high school students by e-questionnaires (mean age = 16.85 years, SD = 1.23). The results showed that: (1) Peer alienation was positively correlated with cyber flaming, cyber pornography and cyber deception; core self-evaluation, father-child relationship and mother-child relationship were negatively correlated with peer alienation, cyber flaming, cyber pornography and cyber deception; (2) Peer alienation had significant positive predictive effects on cyber flaming, cyber pornography and cyber deception, and core self-evaluation played significant mediating roles in these relationships; (3) The mediating paths 'peer alienation [right arrow] core self-evaluation [right arrow] cyber flaming/cyber pornography/cyber deception' were significantly moderated by mother-child relationship, and the mediation effects were more significant among adolescents with lower quality of mother-child relationship. (4) The direct paths 'peer alienation [right arrow] cyber flaming/cyber pornography/cyber deception' were significantly moderated by gender, and the predictive effects were only significant among boys than girls. The current study is conductive to clarify the risk and protective factors for cyber deviant behaviors of adolescents, and mental health professionals should develop safe social interaction programs for adolescents at risk of cyber deviant behaviors., Author(s): Hongxia Wang [sup.1] , Xingchao Wang [sup.2] , Jingyu Geng [sup.1] , Pan Zeng [sup.1] , Xiao Gu [sup.1] , Li Lei [sup.3] Author Affiliations: (1) grid.24539.39, 0000 0004 [...]

In order to study the corrosion behavior of weathering high strength bolted steel in typical industrial atmospheric environment，samples compared with 35 VB bolts were taken from the industrial trial production of 10.9 grade weathering bolts to carry out the simulated periodic infiltration accelerated corrosion tests of typical industrial atmospheric environment for 24，48，96，168，and 216 hours.The corrosion behavior of high strength bolted steel with weathering resistance in simulated industrial atmosphere was studied by means of corrosion weight loss，XRD，SEM and electrochemical test.Results showed that the corrosion weight loss of both grade 10.9 and 35VB bolted steels increased with the prolongation of corrosion cycle，and the weight loss of grade 10.9 weathering bolted steel was significantly lower than that of grade 35VB bolted steel.With the prolongation of corrosion period，the diffraction peak strength of the corrosion products of the 10.9 grade weathering bolted steel and 35VB bolted steel increased，and the α-FeOOH phase diffraction peak was stronger in the 10.9 grade weathering bolted steel under the same corrosion period.Under the same period，compared with 35VB bolted steel，the self-corrosion potential of 10.9 grade weathering bolted steel was more positive，the self-corrosion current density was smaller，and the capacitance resistance arc was larger.The results indicated that the 10.9 grade weathering bolted steel with the addition of Cu，Cr and Ni alloy elements possessed excellent corrosion resistance in typical industrial atmospheric environment.

The present study aimed to explore the predicting role of selfie-editing in cosmetic surgery consideration among adolescents. The influence of facial dissatisfaction on adolescents' cosmetic surgery consideration was also investigated. Furthermore, we examined the possible mediating effects and the potential gender differences in the mediation model. The model was tested with 767 Chinese adolescents (383 boys and 384 girls, mean age = 15.78 at Time 1, SD = 1.96) using a longitudinal design. Participants completed selfie-editing, facial dissatisfaction, and cosmetic surgery consideration at baseline and at 6-month follow-up. Results showed that the initial selfie-editing and facial dissatisfaction positively predicted the subsequent cosmetic surgery consideration among adolescents over time. Facial dissatisfaction mediated the link from selfie-editing to cosmetic surgery consideration. No gender differences were found in the mediation model. The findings of this study provide new insight into the relationship between selfie activities and cosmetic surgery and have practical implications for reducing cosmetic surgery among adolescents., Author(s): Yuhui Wang [sup.1] , Xiaoyuan Chu [sup.2] , Jia Nie [sup.3] , Xiao Gu [sup.3] , Li Lei [sup.4] Author Affiliations: (1) grid.28703.3e, 0000 0000 9040 3743, Faculty of [...]
