Social anxiety has been a common problem among college students and has an adverse impact on their adaptation outcomes. Among influential factors, parental marital conflict and attachment (parental ...and peer attachment) have been found to be related to social anxiety symptoms of college students; however, little is known how parental marital conflict and attachment jointly contribute to social anxiety symptoms of college students. The current study explored this issue. Self-reported questionnaires of perception of children of interparental conflict scale, inventory of parent and peer attachment, and the social interaction anxiety scale were administered to 707 undergraduate students (Mean age = 19.27,
SD
= 0.97). Results indicated that perceived parental marital conflict was positively correlated with social anxiety symptoms and was negatively associated with parental and peer attachment. Parental and peer attachments were negatively correlated with social anxiety symptoms. Mediation analyses indicated that perceived parental marital conflict exerted its indirect effect on social anxiety symptoms through a serial multiple mediation role of parental and peer attachment. The present findings highlight the serial multiple mediation role of parental and peer attachment in the relationship between perceived parental marital conflict and social anxiety symptoms of college students.
We present PHENIX measurements for the cross section and double-helicity asymmetry (ALL) in inclusive π0 production at midrapidity from p + p collisions at √s = 510 GeV from data taken in 2012 and ...2013 at the Relativistic Heavy Ion Collider. The next-to-leading-order perturbative-quantum-chromodynamics theory calculation is in excellent agreement with the presented cross section results. The calculation utilized parton-to-pion fragmentation functions from the recent DSS14 global analysis, which prefer a smaller gluon-to-pion fragmentation function. Our π0ALL results follow an increasingly positive asymmetry trend with pT and √s with respect to the predictions and are in excellent agreement with the latest global analysis results. This analysis incorporated earlier results on π0 and jet ALL and suggested a positive contribution of gluon polarization to the spin of the proton ΔG for the gluon momentum fraction range x > 0.05. Finally, the data presented here extend to a currently unexplored region, down to x similar to 0.01, and thus provide additional constraints on the value of ΔG.
The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < p sub(T)< 6 GeV /c at forward and backward rapidity (1.4 < |y| < 2.0) in ...d + Au and p + p collisions at radics sub(N)N= 200 GeV. In central d + Au collisions, relative to the yield in p + p collisions scaled by the number of binary nucleon-nucleon collisions, a suppression is observed at forward rapidity (in the d-going direction) and an enhancement at backward rapidity (in the Au-going direction). Predictions using nuclear-modified-parton-distribution functions, even with additional nuclear-p sub(T)broadening, cannot simultaneously reproduce the data at both rapidity ranges, which implies that these models are incomplete and suggests the possible importance of final-state interactions in the asymmetric d + Au collision system. These results can be used to probe cold-nuclear-matter effects, which may significantly affect heavy-quark production, in addition to helping constrain the magnitude of charmonia-breakup effects in nuclear matter.
Charged-pion-interferometry measurements were made with respect to the second-and third-order event plane for Au + Au collisions at radical super(S)NN 200 GeV. A strong azimuthal-angle dependence of ...the extracted Gaussian-source radii was observed with respect to both the second-and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced during the medium evolution, which is consistent with previous results. In contrast, the results for the third-order dependence indicate that the initial triangular shape is significantly reduced and potentially reversed by the end of the medium evolution, and that the third-order oscillations are largely dominated by the dynamical effects from triangular flow.
