摘要：
Previous research implies a positive relationship between job stressors and cyberloafing, but that may be half the story. Under the challenge-hindrance stressors framework and conservation of resources theory, we propose that the impact of stressors on cyberloafing depends on the nature of stressors that employees encountered. Using a sample of 498 employees from various fields, we tested a conceptual model in which challenge stressors and hindrance stressors have differential effects on cyberloafing through resilience and emotional exhaustion separately. The results revealed that challenge stressors have a negative direct effect on cyberloafing, whereas hindrance stressors have a positive direct effect. Both two types of stressors have positive indirect effects on cyberloafing through emotional exhaustion. However, even though challenge stressors were positively related to resilience and hindrance stressors were negatively related to resilience, our data did support the mediating role of resilience between job stressors and cyberloafing. Theoretical and practical implications are discussed.

摘要：
The present research explored the selfishness of power and status as well as the mechanism in Chinese work situations. By using experimental and survey methods, two studies were designed to investigate the relationships among power, status, and self-interested behaviour (SIB) as well as the mediating effect of perspective-taking (PT). Results of the two studies consistently indicated that power increases whereas status reduces SIB. These opposing behavioural effects are partially attributed to the fact that power reduces whereas status increases PT. In addition, our results showed an interaction between power and status on SIB in Study 1 (interaction as a mental function), and a positive correlation between perceived power and status in Study 2 (correlation as a mental perception). Through the discussion from the perspective of the self/other-orientation trait, as well as the stable effects of power and status on SIB in the two studies, we conclude that power is selfish and status is unselfish in Chinese work situations.

摘要：
Sense of entitlement can be defined as a pervasive sense that one deserves more and is entitled to more than others. Two studies examined the relationship between social class and sense of entitlement and how this relationship is moderated by system-justifying belief (SJB) in China. In Study 1, we conducted a survey among adults (N = 669) with results showing that social class was positively correlated with sense of entitlement for those endorsing SJB, but negatively correlated with sense of entitlement for those opposing SJB. In Study 2, we conducted an experiment among undergraduates (N = 128) with both social class and SJB being primed and the results replicated the pattern: the positive effect of primed higher social class on pay entitlement existed only for those primed with high SJB, and was dampened for those primed with low SJB. Therefore, higher-class individuals do not necessarily feel more entitled, and SJB may play an important role in shaping their sense of entitlement.

摘要：
The current study examined the associations among cumulative risk, psychological capital and adolescents’ anxiety/depression and life satisfaction. Chinese adolescents (N = 1473, grades 7 to 12, ages 12 to 18, 52.1% female) completed self-report cumulative risk, psychological capital, anxiety/depressive symptoms and life satisfaction questionnaires. Cumulative risk was associated with anxiety/depression and life satisfaction. Psychological capital demonstrated a compensatory effect on youth adjustment. Furthermore, a cost of resilience was observed in high-school students with high psychological capital, who showed compromised life satisfaction in conjunction with reduced anxiety/depression under circumstances of severe adversity. Psychological capital also buffered the impact of cumulative risk on anxiety/depressive symptoms in middle-school students; however, it did not moderate the relationship between cumulative risk and life satisfaction. Therefore, psychological capital cannot protect adolescents exposed to cumulative risk from the exacerbation of psychopathology and declining life satisfaction simultaneously, and a ‘toll’ exists as a byproduct of resilience in high-school students. Suggestions for school health practices were provided accordingly.

摘要：
The present research explores how culture influences individuals’ psychological proximity to the past and future, which may predict differences in perceived self-continuity across time. In Studies 1 and 2, we hypothesized and found that Chinese participants saw the past and future as more connected and subjectively closer to the present compared to Euro-Canadians. Following this, we expected and found in Studies 3 and 4 that Chinese participants perceived greater self-continuity over time than Euro-Canadians. Additionally, perceived closeness to the past mediated the effect of culture on past–present self-continuity, which subsequently predicted present–future self-continuity. Study 5 further documented a causal effect of perceived distance to the past on self-continuity. These results suggest that cultural differences in temporal attention to the past and future play a pivotal role in people's sense of self-continuity across time. This has important implications for temporal focalism, intertemporal discounting, and social interactions between Chinese and Euro-Canadians. © 2018 John Wiley & Sons, Ltd.

摘要：
A measurement of the ratio of branching fractions of the decays B+→K+μ+μ-and B+→K+e+e-is presented. The proton-proton collision data used correspond to an integrated luminosity of 5.0 fb-1 recorded with the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. For the dilepton mass-squared range 1.1<q2<6.0 GeV2/c4 the ratio of branching fractions is measured to be RK=0.846-0.054+0.060-0.014+0.016, where the first uncertainty is statistical and the second systematic. This is the most precise measurement of RK to date and is compatible with the standard model at the level of 2.5 standard deviations. © 2019 CERN.

摘要：
Human-computer interactions keep changing the way humans experience the world, yet the underlying mechanism for such interactions remains obscure. As humans’ bodily experiences play an important role in cognition, the current study designed three experiments to investigate whether individuals with different extent of internet use experience would perform differently in a lexical decision task in which words related to body movement in different ways were used as stimuli. All the experiments were conducted in a five-step sequence: the lexical decision pre-test, the body representation pre-measurement, the tool-use training, the body representation post-measurement, and the lexical decision post-test. The participants with high (N = 32 in Exp. 1, N = 20 in Exp. 2, N = 18 in Exp. 3, respectively) or low (N = 28 in Exp. 1, N = 23 in Exp. 2, N = 22 in Exp. 3) level of internet-use experience were recruited. The results of the study revealed that both groups of the participants performed differently in a lexical decision task when the words used in the task were action verbs or nouns which refer to the tools used in the immediate space of the body, but not when words included metaphorical orientation information related to body movement. This study provided further empirical evidence for the impact of internet use experience on individual's conceptual processing via body representation changes. © 2018 Elsevier Ltd

摘要：
Cyber victimization is a serious risk factor for the manifestation of depressive symptoms in adolescents. However, little is known about the mediating and moderating mechanisms underlying the relationship between these factors. The present study sought to determine whether psychological insecurity mediated the relationship between cyber victimization and depressive symptoms in adolescents. Additionally, this study sought to determine whether this mediating process was moderated by perceived social support. A sample of 793 Chinese adolescents (mean age = 14.41 years, SD = 1.70) completed questionnaires regarding their experience with cyber victimization, psychological insecurity, perceived social support, and depression. Results showed that (a) after controlling for demographics and traditional offline victimization, cyber victimization uniquely predicted a greater prevalence of depressive symptoms; (b) psychological insecurity partially mediated the relationship between cyber victimization and depressive symptoms in adolescents; and (c) perceived social support moderated the direct and indirect paths such that the relationship between psychological insecurity and depression was weaker for adolescents with higher levels of perceived social support (i.e., the stress-buffering effect), but the relationship between cyber victimization and psychological insecurity/depression was stronger for adolescents with higher levels of perceived social support (i.e., the reverse stress-buffering effect). This study contributes to research clarifying the mediating and moderating mechanisms involved in the development of depression among adolescents reporting cyber victimization. © 2018 Elsevier Ltd

摘要：
The ratio of branching fractions R(D∗-)≡B(B0→D∗-τ+ντ)/B(B0→D∗-μ+νμ) is measured using a data sample of proton-proton collisions collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. For the first time, R(D∗-) is determined using the τ-lepton decays with three charged pions in the final state. The B0→D∗-τ+ντ yield is normalized to that of the B0→D∗-π+π-π+ mode, providing a measurement of B(B0→D∗-τ+ντ)/B(B0→D∗-π+π-π+)=1.97±0.13±0.18, where the first uncertainty is statistical and the second systematic. The value of B(B0→D∗-τ+ντ)=(1.42±0.094±0.129±0.054)% is obtained, where the third uncertainty is due to the limited knowledge of the branching fraction of the normalization mode. Using the well-measured branching fraction of the B0→D∗-μ+νμ decay, a value of R(D∗-)=0.291±0.019±0.026±0.013 is established, where the third uncertainty is due to the limited knowledge of the branching fractions of the normalization and B0→D∗-μ+νμ modes. This measurement is in agreement with the standard model prediction and with previous results. © 2018 CERN, for the LHCb Collaboration.

摘要：
We investigated consequences of receiving thanks in close relationships across cultures. Chinese reported more negative feelings than Euro-Canadians after a close other said thanks to them. Likewise, Chinese participants predicted, more than Euro-Canadians did, that a close other would experience negative feelings after receiving thanks from them. No cultural difference was found when receiving thanks from an acquaintance. On the other hand, when not receiving thanks from close others after helping them, Euro-Canadians experienced more negative feelings than did Chinese. We showed that beliefs about saying thanks in close relationships accounted for cultural differences in emotions. Implications for intercultural communication, relationship maintenance, and directions for future research are discussed. © 2017 American Psychological Association.

摘要：
Searches are performed for both promptlike and long-lived dark photons, A′, produced in proton-proton collisions at a center-of-mass energy of 13 TeV, using A′→μ+μ- decays and a data sample corresponding to an integrated luminosity of 1.6 fb-1 collected with the LHCb detector. The promptlike A′ search covers the mass range from near the dimuon threshold up to 70 GeV, while the long-lived A′ search is restricted to the low-mass region 214<m(A′)<350 MeV. No evidence for a signal is found, and 90% confidence level exclusion limits are placed on the γ-A′ kinetic-mixing strength. The constraints placed on promptlike dark photons are the most stringent to date for the mass range 10.6<m(A′)<70 GeV, and are comparable to the best existing limits for m(A′)<0.5 GeV. The search for long-lived dark photons is the first to achieve sensitivity using a displaced-vertex signature. © 2018 authors. Published by the American Physical Society.

摘要：
A search for the rare decay Σ+→pμ+μ- is performed using pp collision data recorded by the LHCb experiment at center-of-mass energies s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. An excess of events is observed with respect to the background expectation, with a signal significance of 4.1 standard deviations. No significant structure is observed in the dimuon invariant mass distribution, in contrast with a previous result from the HyperCP experiment. The measured Σ+→pμ+μ- branching fraction is (2.2-1.3+1.8)×10-8, where statistical and systematic uncertainties are included, which is consistent with the standard model prediction. © 2018 CERN, for the LHCb Collaboration.

摘要：
Studies of Internet addiction (IA) under the cognitive-behavioral framework have suggested that IA derived from the excessive expectation of positive outcomes, which was a goal-directed behavioral progress. However, according to the dual-system account under the framework of associative learning theory, IA should be considered as a transition process from goal-directed to habit-based. It can be explained in terms of aberrant learning processes, where Internet addicts apparently succumb to habit with decreased sensitivity to reward devaluation. To test this hypothesis, we implemented an instrumental learning paradigm to investigate the difference of reliance on habit between Internet addicts and non-addicts. A total of 21 Internet addicts and 23 normal control subjects were trained in the first experimental phase and learned to associate stimuli with rewarding outcomes by pressing correct keys. In the subsequent outcome devaluation test and in the stimulus-response (S-R) habit test, subjects were required to adjust responses to changes in the value of current outcomes. Results revealed that (1) all subjects were able to gradually acquire the correct behavioral responses in the training phase, however, (2) extensive training rendered Internet addicts less sensitive to outcome devaluation in the outcome devaluation test, and (3) Internet addicts insisted on responding to previous stimuli in the S-R habit test, regardless of whether their responses were rewarded. Thus, we conclude that Internet addicts have an enhanced propensity to develop stimulus-driven habits and overly rely on it, leading to the failures to adjust behavior during goal reevaluation. © 2018 Elsevier Ltd

摘要：
Herein, gas bubbles generated in situ from precursors assist the rapid construction of hollow sycamore fruit-like CoMoO4 spheres (HSCSs). This bubble-assisted fabrication strategy is easy to operate, ultra-fast, low cost and post-treatment-free, showing great potential for the large-scale production of HSCSs. The growth mechanism of HSCSs is discussed to reveal the evolution process, which may be generalized to the construction of a series of hollow ternary Mo-based oxides. The obtained HSCSs exhibit a superior specific capacitance and outstanding cyclic stability when applied in supercapacitors.

Adolescents;Deviant peer affiliation;Family functioning;Internet addiction;Social sensitivity
摘要：
Poor family functioning is an established risk factor in adolescent Internet addiction; however, little is known about the mechanisms underlying this relation. Inspired by the ecological model (Bronfenbrenner, 1979), the current study attempts to explain the association between family functioning and adolescent Internet addiction by testing the potential mediating role of deviant peer affiliation and the moderating role of social sensitivity. A total of 863 Chinese adolescents (M age = 14.34 years; SD = 1.66; 45% males) completed anonymous questionnaires regarding demographics, family functioning, deviant peer affiliation, social sensitivity, and Internet addiction. After covariates were controlled, the results indicated that deviant peer affiliation partially mediated the negative relation between family functioning and Internet addiction among both males and females. Additionally, the second part of the indirect link was moderated by social sensitivity among females, such that deviant peer affiliation significantly predicted Internet addiction in females with moderate and high but not low social sensitivity. The moderating role of social sensitivity was not significant among adolescent males. The theoretical and practical implications of these findings are discussed. © 2018 Elsevier Ltd

摘要：
The first observation of the D0→π+π-μ+μ- and D0→K+K-μ+μ- decays is reported using a sample of proton-proton collisions collected by LHCb at a center-of-mass energy of 8 TeV, and corresponding to 2 fb-1 of integrated luminosity. The corresponding branching fractions are measured using as normalization the decay D0→K-π+[μ+μ-]ρ0/ω, where the two muons are consistent with coming from the decay of a ρ0 or ω meson. The results are B(D0→π+π-μ+μ-)=(9.64±0.48±0.51±0.97)×10-7 and B(D0→K+K-μ+μ-)=(1.54±0.27±0.09±0.16)×10-7, where the uncertainties are statistical, systematic, and due to the limited knowledge of the normalization branching fraction. The dependence of the branching fraction on the dimuon mass is also investigated. © 2017 CERN, for the LHCb Collaboration. Published by the American Physical Society.

摘要：
A search for the rare decays Bs0→τ+τ- and B0→τ+τ- is performed using proton-proton collision data collected with the LHCb detector. The data sample corresponds to an integrated luminosity of 3 fb-1 collected in 2011 and 2012. The τ leptons are reconstructed through the decay τ-→π-π+π-ντ. Assuming no contribution from B0→τ+τ- decays, an upper limit is set on the branching fraction B(Bs0→τ+τ-)<6.8×10-3 at the 95% confidence level. If instead no contribution from Bs0→τ+τ- decays is assumed, the limit is B(B0→τ+τ-)<2.1×10-3 at the 95% confidence level. These results correspond to the first direct limit on B(Bs0→τ+τ-) and the world's best limit on B(B0→τ+τ-). © 2017 CERN. for the LHCb Collaboration.

摘要：
The production of J/ψ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the J/ψ meson, z(J/ψ)≡pT(J/ψ)/pT(jet), is measured using jets with pT(jet)>20 GeV in the pseudorapidity range 2.5<η(jet)<4.0. The observed z(J/ψ) distribution for J/ψ mesons produced in b-hadron decays is consistent with expectations. However, the results for prompt J/ψ production do not agree with predictions based on fixed-order nonrelativistic QCD. This is the first measurement of the pT fraction carried by prompt J/ψ mesons in jets at any experiment. © 2017 CERN.
