The Ending Effect in the Domain of Gambling: The Effect of Gain-Loss Status on Economic Decision-Making

Previous studies have shown that people prefer risk-taking at the end of gambles, a phenomenon called the ending effect. By using the Guess Gambling Game, we investigated the impact of gain-loss status on the ending effect (Experiment 1) and whether and how this effect may be affected by time reference (Experiment 2) and gender (Experiment 1&2). In Experiment 1, we observed the ending effect only in the gain group. Furthermore, gender differences exist in the loss group behavior, females were more risk-averse than males, and males tend to investment more initially and then reduce their investment in a U-shaped pattern (Experiment 1&2). Next, in Experiment 2, the findings indicated that participants in the gain group made riskier decisions and were willing to allocate more money for additional decision opportunities, irrespective of the time conditions. Additionally, under time-limited condition, participants tended to make more decisions in the final round, aiming to maximize their choices times within the limited time. These results contribute to a better understanding of the boundary conditions surrounding the ending effect in risky decision-making and may offer a scientific basis for mitigating and intervening in irrational decision-making.

Lipoprotein(a) is associated with recurrent cardiovascular events in patients with coronary artery disease and prediabetes or diabetes

PURPOSE

Elevated lipoprotein(a) [Lp(a)] and diabetes mellitus (DM) are both associated with adverse events in high-risk patients with established coronary artery disease (CAD). Currently, the association between Lp(a) levels and recurrent cardiovascular (CV) events (CVEs) remained undetermined in patients with different glucose status. Therefore, this study aimed to investigate the prognostic significance of Lp(a) levels for recurrent CVEs in high-risk CAD patients who suffered from first CVEs according to different glycemic metabolism.

METHODS

We recruited 5257 consecutive patients with prior CVEs and followed up for recurrent CVEs, including CV death, non-fatal myocardial infarction (MI), and non-fatal stroke. Patients were assigned to low, medium, and high groups according to Lp(a) levels and further stratified by glucose status.

RESULTS

During a median 37-month follow-up, 225 (4.28%) recurrent CVEs occurred. High Lp(a) was independently associated with recurrent CVEs [adjusted Hazard Ratio (HR), 1.57; 95% confidence interval (CI) 1.12-2.19; P = 0.008]. When participants were classified according to Lp(a) levels and glycemic status, high Lp(a) levels were associated with an increased risk of recurrent CVEs in pre-DM (adjusted HR, 2.96; 95% CI 1.24-7.05; P = 0.014). Meanwhile, medium and high Lp(a) levels were both associated with an increased risk for recurrent CVEs in DM (adjusted HR, 3.09; 95% CI 1.30-7.34; P = 0.010 and adjusted HR, 3.13, 95% CI 1.30-7.53; P = 0.011, respectively).

CONCLUSIONS

This study demonstrated that elevated Lp(a) levels were associated with an increased recurrent CVE risk in patients with CAD, particularly among those with pre-DM and DM, indicating that Lp(a) may provide incremental value in risk stratification in this population.

Parental self-control facilitates adolescent psychological adjustment sequentially through parents' perceived stress/mindful parenting and adolescent self-control

Adolescence is a unique developmental period marked with significant changes and challenges. As such, maintaining optimal psychological adjustment is crucial for young people, especially during the COVID-19 pandemic when their adjustment became more challenging. Self-control is a vital ability assisting individuals to navigate difficulties and stay well-adjusted during turbulent times. While the associations between adolescent self-control and adjustment have been well-documented, parental self-control has been considered to play a more fundamental role in adolescent adjustment. However, this consideration has received scant research. Drawing on the intergenerational transmission model of self-regulation, we examined an understudied yet plausible idea that parental self-control facilitates adolescent adjustment through parents' lower levels of perceived stress/better mindful parenting and adolescents' improved self-control. A two-wave survey study, spanning 1 year apart, was conducted among 426 Chinese adolescents (Mage = 11.6 years, 53.5% boys) and their parents. Parents rated their self-control, perceived stress, and mindful parenting at T1, while adolescents rated their self-control and adjustment (i.e., psychological difficulties and life satisfaction) at T1 and T2. The results of chain mediation model showed that after controlling for demographic covariates and baseline levels of adolescent self-control and adjustment, T1 paternal self-control facilitated T2 adolescent adjustment through fathers' lower levels of perceived stress and adolescents' improved self-control. By contrast, T1 maternal self-control facilitated T2 adolescent adjustment through mothers' better mindful parenting and adolescents' improved self-control. These findings advance our understanding of how self-control is transmitted from parents to offspring and clarify the processes of how parental self-control facilitates adolescent adjustment.

Hemolysis dictates monocyte differentiation via two distinct pathways in sickle cell disease vaso-occlusion

Sickle cell disease (SCD) is a hereditary hemoglobinopathy characterized by painful vaso-occlusive crises (VOC) and chronic hemolysis. The mononuclear phagocyte system is pivotal to SCD pathophysiology, but the mechanisms governing monocyte/macrophage differentiation remain unknown. This study examined the influence of hemolysis on circulating monocyte trajectories in SCD. We discovered that hemolysis stimulated CSF-1 production, partly by endothelial cells via Nrf2, promoting classical monocyte (CMo) differentiation into blood patrolling monocytes (PMo) in SCD mice. However, hemolysis also upregulated CCL-2 through IFN-I, inducing CMo transmigration and differentiation into tissue monocyte-derived macrophages. Blocking CMo transmigration by anti-P selectin antibody in SCD mice increased circulating PMo, corroborating that CMo-to-tissue macrophage differentiation occurs at the expense of CMo-to-blood PMo differentiation. We observed a positive correlation between plasma CSF-1/CCL-2 ratios and blood PMo levels in patients with SCD, underscoring the clinical significance of these two opposing factors in monocyte differentiation. Combined treatment with CSF-1 and anti-P selectin antibody more effectively increased PMo numbers and reduced stasis compared with single-agent therapies in SCD mice. Altogether, these data indicate that monocyte fates are regulated by the balance between two heme pathways, Nrf2/CSF-1 and IFN-I/CCL-2, and suggest that the CSF-1/CCL-2 ratio may present a diagnostic and therapeutic target in SCD.

Preparation of High Water-Soluble Trichoderma Co-Culture Metabolite Powder and Its Effects on Seedling Emergence Rate and Growth of Crops

Trichoderma spp. are widely used beneficial microbes in agricultural production; however, the improper carrier choice for Trichoderma agent preparation can alter the effectiveness of Trichoderma fungicides. In this study, the co-culture of four Trichoderma strains produced a large amount of free amino acids, with a content of 392.8414 ug/mL, and significantly improved the production level of γ-aminobutyric acid. A greenhouse experiment further showed that the co-culture of Trichoderma synergistically improved the female flower development and bacterial angular leaf spot resistance. The effects of ten kinds of carriers were compared in terms of water absorption and heat generation, as well as their effects on the seedling emergence rate and the plant growth promotion of maize, cucumber, and pakchoi cabbage. Each carrier was screened to mix with four strains of co-culture metabolites to prepare highly soluble and quality powders. The results showed that there were different effects of the carriers themselves and Trichoderma strain co-culture metabolite powder prepared with the carriers on seedling emergence rate and seedling growth. Β-cyclodextrin performed best in high solubility and low heat generation upon absorbing water and in easy drying in processing operations. Trichoderma strains co-culture metabolite powder with β-cyclodextrin as a carrier provided the most obvious promotion effects on seedling emergence rate and seedling growth. Therefore, β-cyclodextrin was determined to be an ideal carrier to prepare a highly water-soluble Trichoderma agent. Taken together, the study successfully developed a new type of highly soluble powder containing Trichoderma co-culture metabolites that is expected to benefit farming drip irrigation and spraying systems for the promotion of crop growth and disease control.

Longitudinal association between interparental conflict and risk-taking behavior among Chinese adolescents: testing a moderated mediation model

BACKGROUND

The interparental conflict has been associated with an increased adolescents' engagement in risk-taking behaviors. However, few studies have examined the potential mediation of deviant peer affiliation and the potential moderation of school climate. Grounded in the ecological system theory, this study aimed to explore the mediating role of deviant peer affiliation and the moderating role of school climate between the association of interparental conflict and risk-taking behavior.

METHODS

This study conducted a longitudinal design (3 time points, 3 months apart) with the sample comprising 550 middle school students in southeastern China (52.91% males; mean age at Time 1 = 15.37). The performed measurements encompassed interparental conflict (T1), deviant peer affiliation (T2), school climate (T3), risk-taking behavior (T1/T2/T3), and demographic information.

RESULTS

The moderated mediation model revealed that after controlling for T1/T2 risk-taking behavior, T1 interparental conflict was longitudinally and positively correlated with T3 risk-taking behavior through T2 deviant peer affiliation. Furthermore, moderated mediation analysis demonstrated that a positive school climate ameliorated the adverse impact of deviant peer affiliation on risk-taking behavior, thereby mitigating the indirect effect of interparental conflict on risk-taking behavior among adolescents.

CONCLUSIONS

Our findings propose a nuanced explanation of the processing mechanisms between interparental conflict and risk-taking behaviors among Chinese adolescents. The theoretical and practical implications of the findings are discussed.

High-efficiency adsorption removal of CR and MG dyes using AlOOH fibers embedded with porous CoFe2O4 nanoparticles

Owing to the toxicity and difficulty in degradation, how to the effective separation for the residual dyes in the aqueous solution is still an issue with great challenge in the area of environmental protection. Now, to high-efficiency removal of organic dyes from the aqueous solution, we design a unique AlOOH/CoFe₂O₄ adsorbent with porous CoFe₂O₄ nanoparticles embedded on the AlOOH fibers using a simple hydrothermal technique and calcination process. The structural properties and surface characteristics of the AlOOH/CoFe₂O₄ composites are detailedly analyzed by XRD, FTIR, XPS, TEM and SEM. Here, the high S_BET and specific porous structure are beneficial to improve the adsorption performance of AlOOH/CoFe₂O₄ adsorbents. Especially, when the molar ratio of AlOOH to CoFe₂O₄ in the AlOOH/CoFe₂O₄ fibers is 1:1, an optimal performance on adsorbing anionic Congo red (CR) and cationic methyl green (MG) dyes can be obtained at pH = 6.29, where the corresponding maximum adsorption capacities reach up to 565.0 and 423.7 mg g^-1, respectively. Factors leading to the change in the ability of adsorbing CR and MG dyes are systematically discussed, including contact time, temperature, initial concentrations, and pH values of the solutions. Meanwhile, the uptake of CR and MG dyes can best conform to Langmuir isotherm model and pseudo-second-order adsorption kinetics. The thermodynamic analysis verifies that the dye adsorption process is spontaneous and endothermic. Moreover, from the point view of practical application, the good reusability further makes the as-synthesized magnetic AlOOH/CoFe₂O₄ composite be a perfect adsorbent with efficiently removing both anionic and cationic dyes from aqueous solutions.

The Association between Peer Victimization and Risk-Taking Behavior among Chinese Adolescents: Testing a Moderated Mediation Model

Peer victimization has been considered a main source of risk-taking behavior among adolescents, but little is known about the mechanisms underlying this association. Based on the social-cognitive theory and the person-environment interactions model, the current study built a moderated mediation model to explore whether self-control mediated the link between peer victimization and adolescent risk-taking behavior and whether positive parenting moderated this link. We used a 2-time longitudinal design (6 months apart) to investigate 488 adolescents (M_age = 15.63 years, SD = 1.64) from 3 middle schools in Guangzhou. The results were as follows: (1) There were significant correlations among peer victimization, adolescent risk-taking behavior, self-control, and positive parenting when controlling for demographic variables. (2) Peer victimization not only influenced risk-taking behavior directly, but also indirectly through self-control. (3) Positive parenting moderated the influence of self-control on risk-taking behavior. In other words, positive parenting could enhance the inhibitory effect of self-control on risk-taking behavior. The results help reveal the mechanism by which adolescent risk-taking behavior forms and may help inform interventions against adolescent risk-taking behavior.

Longitudinal association between parental involvement and internet gaming disorder among Chinese adolescents: Consideration of future consequences as a mediator and peer victimization as a moderator

BACKGROUND AND AIMS

Internet gaming disorder (IGD) in adolescents is a concerning issue. Positive parenting has been found to protect against adolescent IGD, but the underlying mechanisms await further investigation. As such, this study examined the longitudinal association between parental involvement (PI) - a specific type of positive parenting understudied in the literature of adolescent gaming disorder - and IGD. Moreover, this study also tested consideration of future consequences (CFC) as a mediator and peer victimization (PV) as a moderator.

METHODS

A two-wave longitudinal research spanning 6 months apart was conducted. Participants were Chinese adolescents (final N = 434; 222 females; Mage = 14.44 years, SD = 1.56). They provided ratings on PI, PV, and IGD at Wave 1, and CFC-immediate, CFC-future, and IGD at Wave 2.

RESULTS

Descriptive statistics showed that the prevalence rate of IGD was 10.81% and 9.45% at Waves 1 and 2, respectively. Moreover, results of moderated mediation model found that after controlling for Wave 1 IGD and covariates, Wave 1 PI was associated with Wave 2 IGD via preventing adolescents who had higher levels of PV from developing a tendence of CFC-immediate and via promoting adolescents who had lower levels of PV to develop a tendence of CFC-future.

DISCUSSION AND CONCLUSIONS

Altogether, these results suggest that facilitative ecological systems (e.g., positive parenting and good relationships with peers) and personal strengths (e.g., positive future orientation) jointly contribute to the mitigation of adolescent IGD.

Theory of planned behavior explains males' and females' intention to receive COVID-19 vaccines differently

Uptake of COVID-19 vaccines is an important measure to curb the transmission of the coronavirus. Before the vaccines were available, numerous studies found that people had a moderate-to-high intention to receive the vaccines. Several studies have also used the theory of planned behavior (TPB) to predict people’s COVID-19 vaccination intention with three elements (i.e. attitudes, subjective norms, and perceived behavioral control) . However, the vaccination rate falters after the vaccines became available, and there were few updated data documenting people’s vaccination intention and how well TPB can explain their intention. In addition, studies investigating other outcomes found that the predictive utilities of TPB often varied across gender, but such gender differences received little consideration in the literature of COVID-19 vaccination intention. To help fill these gaps, we examined the associations between TPB elements and people’s intention to receive COVID-19 vaccines and the moderation of gender in the context of vaccination campaign. Participants were 405 Chinese citizens. They reported on the three TPB elements and intention to receive vaccines in the coming months. Descriptive results showed that participants’ vaccination intention was moderate. Results of path analysis showed that subjective norms and perceived behavioral control were positively related to vaccination intention for the whole sample. Furthermore, results of multigroup path analysis showed that attitudes were only related to males’, while subjective norms were only related to females’, intention. These findings enhance the utility of TPB in explaining people’s COVID-19 vaccination intention and inform gender-specific strategies to boost males’ and females’ vaccination intention.

Linking Self-Control to Negative Risk-Taking Behavior among Chinese Late Adolescents: A Moderated Mediation Model

Negative risk-taking behaviors refer to voluntary behaviors that lead to more harm than good. Low self-control is a crucial predictor of adolescents’ negative risk-taking behavior, but its internal mechanisms require further exploration. To reveal the working process underlying the association between self-control and adolescents’ negative risk-taking behaviors, we investigated the mediation of regulatory focus and the moderation of sense of power. A total of 2018 students (37.6% males) from two universities in Guangzhou, China, participated in a survey that investigated their self-control, negative risk-taking behavior, regulatory focus and sense of power. The results revealed that after controlling for the adolescents’ sex and their parents’ educational level, prevention focus partially mediated the association between self-control and negative risk-taking behavior. Moreover, sense of power moderated the association between self-control and prevention focus. Furthermore, the association between self-control and negative risk-taking behavior through prevention focus was stronger among adolescents with a high sense of power than among those with a low sense of power. Therefore, our findings suggest that regulatory focus and sense of power might be the mechanisms that explain how self-control is related to negative risk-taking behavior. These results thus provide a foundation for the prevention of and intervention in adolescents’ negative risk-taking behavior.

The Interpretation of the Role of a Polyketide Synthase ClPKS18 in the Pathogenicity of Curvularia lunata

Plant pathogenic fungus Curvularia lunata (Wakker) Boedijn causes leaf spot diseases in several plants such as Oryza sativa, Sorghum bicolor (L.) Moench, and Capsicum frutescens. It has been spread worldwide, specifically in maize-growing regions. The polyketide synthase (PKS) plays a significant role in secondary metabolite production and its effect on virulence. The Clpks18 of C. lunata strongly correlated with its pathogenicity. The role of Clpks18 gene on the pathogenic activity of C. lunata remains unclear. Hence, in this study, we analyzed the importance of Clpks18 gene on the hyphae and conidial melanization and on the sporulation and hyphal growth. The deletion of Clpks18 gene reduced the production of methyl 5-(hydroxymethyl)furan-2-carboxylate toxin. The virulence of ΔClpks18 mutant was significantly reduced compared with the wild type. The metabolomics data revealed that (R)-(-)-mellein was a vital factor in the virulence of C. lunata. The (R)-(-)-mellein and the toxin produced by C. lunata were detected in the maize leaves during its infestation. In addition, the metabolomic analysis showed that the Clpks18 gene influences glycerolipid, non-ribosomal peptide biosynthesis, and its metabolism. This study demonstrates that the Clpks18 gene is important for the pathogenicity of C. lunata by influencing the complex metabolic network.

Longitudinal association between poor parental supervision and risk-taking behavior: The role of self-control and school climate

INTRODUCTION

Although poor parental supervision has been associated with an increased adolescents' propensity for risk-taking behavior, few researchers have investigated nuanced mechanisms of how and for whom from the perspective of "family × school." Inspired by ecological system theory and self-control theory, this study aimed to investigate the mediating role of self-control and the moderating role of school climate between the link between poor parental supervision and risk-taking behavior.

METHODS

Four hundred and ninety-one Chinese adolescents (231 females, M_age  = 15.39 ± 1.36) were recruited to participate in a three-wave longitudinal study (3 months apart) and complete questionnaires regarding poor parental supervision (W1), school climate (W1), self-control (W2), and risk-taking behavior (W1/W3).

RESULTS

After controlling for W1 risk-taking behavior, our moderated mediation model indicated that W1 poor parental supervision was positively related to W3 risk-taking behavior by restraining the development of W2 self-control. Additionally, a high level of school climate as a protective factor buffered the negative impact of poor parental supervision on adolescents' self-control, further reducing risk-taking behavior.

CONCLUSION

Our findings shed light on the processing mechanisms between poor parental supervision and risk-taking behavior among Chinese adolescents and underscore the importance of effective preventions and interventions to facilitate adolescents' healthy development.

Profiles of positive changes in life outcomes over the COVID-19 pandemic in Chinese adolescents: the role of resilience and mental health consequence

BACKGROUND

The 2019 coronavirus (COVID-19) has caused enormous negative impacts on adolescents' routines, social interaction, interpersonal relationships, psychosocial well-being, and physical health. Nevertheless, theories suggest that individuals also often seek out solutions that may facilitate positive changes when they are faced with uncertainty and crisis. However, the existing literature has disproportionately focused on the negative effect of COVID-19 on adolescents, and scant research has examined to what extent and in what aspects adolescents would experience positive changes in times of the pandemic. This pre-registered research aims to bridge said gaps by: (1) exploring different profiles of positive changes in various life outcomes in Chinese adolescents over the COVID-19 pandemic; (2) examining the role of resilience in differentiating different profiles; (3) comparing adolescents' mental health across profiles.

METHOD

Participants were 2,567 adolescents aged 12 to 24 recruited from 32 provinces in mainland China (66.89% females; M_age = 19.87 years, SD = 2.02). Through an online survey, participants rated how much their lives of different domains had experienced positive changes since the outbreak of the pandemic. They also answered standardized questionnaires that measured their resilience and mental health.

RESULTS

Results of latent profile analysis revealed three profiles: limited positive changes (33.3%), partial positive changes (49.5%), and overall strong positive changes (17.2%). Moreover, adolescents with a higher level of resilience were more likely to be categorized into the partial positive changes profile compared to the limited positive changes profile and categorized into the overall strong positive changes profile compared to the other two profiles, after controlling for multiple covariates. Adolescents in the overall strong positive changes profile had better mental health than their counterparts of the other two profiles.

CONCLUSION

Chinese adolescents appear to experience positive changes in various life outcomes during the COVID-19 pandemic, especially for those with high levels of resilience. Such positive changes have important implications on adolescents' mental health.

3D porous coral-like Co1.29Ni1.71O4 microspheres embedded into reduced graphene oxide aerogels with lightweight and broadband microwave absorption

In this work, three-dimensional (3D) porous coral-like Co_1.29Ni_1.71O₄ microspheres were successfully combined with reduced graphene oxide (rGO) to form Co_1.29Ni_1.71O₄/rGO aerogels as an efficient microwave absorber by a facile calcination and hydrothermal method. The elemental composition, microstructure, and morphology of the as-synthesized composites were characterized, and the electromagnetic wave absorption performance were analyzed in the frequency range of 2.0-18.0 GHz. The results show that adjusting the mass ratio of Co_1.29Ni_1.71O₄ microspheres and rGO in the composites can effectively tune the electromagnetic parameters, which in turn improves their microwave absorption performance. Here, the minimum reflection loss (RL_min) of the Co_1.29Ni_1.71O₄/rGO aerogels is -51.76 dB with an effective absorption bandwidth (RL < -10 dB) of 7.04 GHz (10.96-18 GHZ) at the thickness of 2.66 mm and a low filling ratio of 15 wt%. It can be demonstrated that the superior microwave absorption performance is attributed to the synergistic effect of impedance matching and dielectric loss, the unique 3D porous structure as well as the abundant interface of the composites. In brief, this study provides a new strategy for the design of magnetic/dielectric high-performance microwave absorbing materials.

The Relationship between Peer Attachment and Aggressive Behavior among Chinese Adolescents: The Mediating Effect of Regulatory Emotional Self-Efficacy

This study aimed to test the association between peer attachment and aggressive behavior, as well as the mediating effect of regulatory emotional self-efficacy on this relationship. A total of 1171 (582 male, 589 female) Chinese adolescents completed self-reported questionnaires that assessed peer attachment, regulatory emotional self-efficacy, and aggressive behavior. Path analysis showed that the negative association between peer attachment and adolescent aggressive behavior was mediated by self-efficacy in managing negative emotions. However, the mediating effect of self-efficacy in expressing positive emotions was nonsignificant. Moreover, there was no significant difference in the indirect paths mentioned above between male and female respondents. These findings highlight self-efficacy in managing negative emotions as a potential mechanism linking peer attachment to adolescent aggressive behavior.

Linking Self-Control to Voluntary Behaviors at Workplace: The Mediating Role of Job Satisfaction

Voluntary work behavior (VWB) refers to spontaneous workplace behaviors that extend beyond role norms, including extra-role behaviors that benefit the organization (i. e., organizational citizenship behavior, OCB) and negative behaviors that may harm the organization (i.e., counterproductive work behavior, CWB). This study examined the relationship between self-control and VWB and the mediating role of job satisfaction. A total of 1,101 full-time employees from China completed a battery of self-report measures online. The results show that self-control positively predicts employees' OCB and negatively predicts employees' CWB. Moreover, job satisfaction significantly mediates the relationship between self-control and OCB/CWB. The results confirm that employees with high self-control are more public-spirited, which previous studies have described as being “highly committed” (high OCB) or “less harmful” (low CWB). This finding closely relates to the observation that employees with high self-control tend to have more satisfying work outcomes or higher workplace status than those with low self-control.

Prognostic implications of 2018 ESC/EACTS guideline-endorsed high ischaemic risk features on clinical outcomes after PCI with drug-eluting stents

Background

Recently, the 2018 ESC/EACTS guidelines on myocardial revascularization have been proposed to standardize the definition of high ischemic events risk (HIR) features. However, the prevalence and the expected ischemic event rate of HIR patients defined by ESC/EACTS-endorsed criteria are currently unknown in the real-world percutaneous coronary intervention practice. We sought to investigate the impact of HIR features on clinical outcomes after drug-eluting stents implantation and whether this effect is influenced by high bleeding risk (HBR).

Methods

Between January 2013 and December 2013, a total of 10,167 consecutive patients undergoing PCI were prospectively enrolled in Fuwai PCI Registry. The primary ischemic endpoint was target lesion failure (TLF) (comprising cardiac death, target vessel myocardial infarction, and target lesion revascularization] and the primary bleeding endpoint was clinically relevant bleeding defined as Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding. Guideline-endorsed HIR features were in the present study and definitions were as follows: diffuse (defined as lesion length ≥20 mm) multivessel disease in patients with diabetes, CKD (defined as estimated glomerular filtration rate &lt;60 ml/min/1.73 m2), ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length &gt;60 mm, and treatment of CTO, and history of ST-elevation myocardial infarction. HBR was defined based on the highest quartile of PARIS bleeding score (≥6 or &lt;6).

Results

Median follow-up was 29 months. 5149 patients had at least 1 HIR feature (50.6%), who experienced significantly increased risks of TLF (adjusted hazard ratio [HR]: 1.59, 95% confidence interval [CI]: 1.32–1.93; P&lt;0.001), compared to those with non-HIR features. In contrast, the risk of clinically relevant bleeding was statistically similar between the 2 groups (HRadjust: 0.85 [0.66–1.09]; P=0.200). By including ESC/EACTS-endorsed HIR criteria as a continuous variable within the same multivariable models, the risk of adverse ischemic events tended to be greater as the number of high-risk procedural characteristics increased (per number of high-risk features increase: for TLF, HRadjust: 1.15, 95% CI: 1.07–1.23; P trend&lt;0.001; for MACE, HRadjust: 1.33, 95% CI: 1.22–1.46; P trend&lt;0.001). There was no statistical interaction between HBR and HIR features in regard to TLF (adjusted Pinteraction=0.855) and clinically relevant bleeding (adjusted Pinteraction=0.269), suggesting a consistent effect within ESC/EACTS-endorsed HIR features. Results were consistent when categorizing patients into HBR according to PARIS bleeding risk score ≥8 points.

Conclusions

ESC/EACTS-endorsed HIR criteria were associated with a substantial risk of ischemic events, with no increase in clinically relevant bleeding in routine clinical practice; and theses associations did not seem to be modified by HBR status.

Benefit-risk profile of longer-than-1-year dual antiplatelet therapy in TWLIGHT-like patients with high risk of ischemic or bleeding events after drug-eluting stents implantation

Background

Dual-antiplatelet therapy (DAPT) exceeding 1 year may increase a bleeding risk despite reducing the risk of ischemic events. The benefits and harms of prolonging DAPT with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for TWLIGHT-like patients with high-risk for bleeding or an ischemic event remain unknown.

Method

Between January 2013 and December 2013, all consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry. We evaluated 7521 patients who were at high risk for ischemic or hemorrhagic complications and were events free (no death, myocardial infarction [MI], stroke, stent thrombosis [ST], any revascularization, or major bleeding) at 1 year after the index procedure. Subjects were divided into 2 groups: DAPT &gt;1-year group (n=5252) and DAPT ≤1-year group (n=2269). Patients at high-risk for ischemic or bleeding events were defined as having at least one additional clinical feature and one angiographic feature according to TWILIGHT trial criteria. The clinical criteria for high risk were age ≥65 years, female sex, troponin-positive ACS, established vascular disease, diabetes mellitus that was being treated with medication, and CKD. Angiographic criteria included multivessel coronary artery disease, total stent length ≥30 mm, a thrombotic target lesion, a bifurcation lesion treated with two stents, an obstructive left main or proximal left anterior descending lesion, and a calcified target lesion treated with atherectomy. The primary outcome was major adverse cardiac and cerebrovascular events [MACCE] (a composite of all-cause death, MI, or stroke).

Results

During a median follow-up of 30 months after the index procedure, DAPT &gt;1-year was associated with a reduction in risk for MACCE compared with DAPT ≤1-year (1.5% vs. 3.8%; adjusted hazard ratio [HR]: 0.36; 95% confidence interval [CI]: 0.27–0.50; P&lt;0.001) after multivariable adjustment. This difference was largely driven by a lower risk of all-cause mortality. In contrast, the risk of BARC type 2, 3 or 5 bleeding was statistically similar between the 2 groups (1.0% vs. 1.1%; adjusted HR: 0.81; 95% CI: 0.50–1.30; P=0.373). After propensity score matching, incidence of MACCE was still lower in the DAPT &gt;1-year group than the DAPT ≤1-year group (1.6% versus 4.5%; HR, 0.34; 95% CI, 0.22–0.52; P&lt;0.001) and the rates of BARC type 2, 3 or 5 bleeding was not different between the 2 groups (1.1% versus 0.9%; adjusted HR, 1.12; 95% CI, 0.57–2.18; P=0.744). In subgroup analysis, the treatment effect of prolonged DAPT was consistent across subgroups regardless of ACS, DAPT score, or type of used DES.

Conclusions

DAPT continuation with aspirin and clopidogrel beyond 1-year after DES implantation resulted in a significantly lower rate of MACCE, with no higher risk of clinically relevant bleeding in TWLIGHT-like patients who were at high-risk for ischemic or bleeding events.

PCI complexity and cardiovascular risk in relation to high bleeding risk among patients receiving drug-eluting Stents: insight from China Fuwai PCI registry

Background

The relation between complex percutaneous coronary intervention (PCI), high bleeding risk (HBR), and adverse events after coronary artery implantation of drug-eluting stents has been incompletely characterized. This study sought to investigate the ischemic and bleeding events after complex PCI including a stratification according to HBR estimated by PARIS bleeding risk score.

Methods

Between January 2013 and December 2013, 10,167 consecutive patients undergoing PCI were prospectively enrolled in Fuwai PCI Registry. Complex PCI was defined when having at least one of the following characteristics: 3 vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length &gt;60 mm, treatment of chronic total occlusion, unprotected left main PCI, in-stent restenosis target lesion, and severely calcified lesion requiring a rotablator system. The primary ischemic endpoint was major adverse cardiovascular events (MACE) [composite of cardiac death, myocardial infarction, and definite/probable stent thrombosis], and primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding.

Results

The median duration of follow-up was 30 months. In adjusted Cox regression analysis, patients having complex PCI procedures experienced higher risks of MACE (hazard ratio [HR]: 1.63, 95% confidence interval [CI]: 1.38–1.92; P&lt;0.001), compared with non-complex PCI. In contrast, the risk of clinically relevant bleeding was statistically similar between the 2 groups (HR: 0.86 [0.66–1.11]; P=0.238). There was no statistical interaction between HBR (PARIS bleeding score ≥8 or &lt;8) and complex PCI in regard to MACE (adjusted Pinteraction=0.388) and clinically relevant bleeding (adjusted Pinteraction=0.279).

Conclusions

Patients who had undergone complex PCI resulted in substantially more ischemic events, without an increase in clinically relevant bleeding risk; and these associations did not seem to be modified by HBR status. More intensified antiplatelet therapy may be beneficial for patients with complex percutaneous coronary revascularization procedures.

PCI complexity and risk of adverse events in relation to high bleeding risk among patients receiving drug-eluting stents

Background

The relation between complex percutaneous coronary intervention (PCI), high bleeding risk (HBR), and adverse events after coronary artery implantation of drug-eluting stents has been incompletely characterized. This study sought to investigate the ischemic and bleeding events after complex PCI including a stratification according to HBR estimated by PARIS bleeding risk score.

Methods

Between January 2013 and December 2013, 10,167 consecutive patients undergoing PCI were prospectively enrolled in Fuwai PCI Registry. Complex PCI was defined when having at least one of the following characteristics: 3 vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length &gt;60 mm, treatment of chronic total occlusion, unprotected left main PCI, in-stent restenosis target lesion, and severely calcified lesion. The primary ischemic endpoint was major adverse cardiovascular events (MACE) [composite of cardiac death, myocardial infarction, and definite/probable stent thrombosis], and primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding.

Results

The median duration of follow-up was 29 months. In adjusted Cox regression analysis, patients having complex PCI procedures experienced higher risks of MACE (hazard ratio [HR]: 1.63, 95% confidence interval [CI]: 1.38–1.92; P&lt;0.001), compared with non-complex PCI. In contrast, the risk of clinically relevant bleeding was statistically similar between the 2 groups (HR: 0.86 [0.66–1.11]; P=0.238). There was no statistical interaction between HBR (PARIS bleeding score ≥8 or &lt;8) and complex PCI in regard to MACE (adjusted Pinteraction=0.388) and clinically relevant bleeding (adjusted Pinteraction=0.279).

Conclusions

Patients who had undergone complex PCI resulted in substantially more ischemic events, without an increase in clinically relevant bleeding risk; and these associations did not seem to be modified by HBR status. More intensified antiplatelet therapy may be beneficial for patients with complex percutaneous coronary revascularization procedures.

Benefit and risks of extended dual antiplatelet therapy beyond 1 year in high-risk patients after drug-eluting stent implantation

Background

Dual-antiplatelet therapy (DAPT) exceeding 1 year may increase a bleeding risk despite reducing the risk of ischemic events. The benefits and harms of prolonging DAPT with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for patients with high-risk for bleeding or an ischemic event remain unknown.

Method

Between January 2013 and December 2013, all consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry. We evaluated 7521 patients who were at high risk for ischemic or hemorrhagic complications and were events free (no death, myocardial infarction [MI], stroke, stent thrombosis [ST], any revascularization, or major bleeding) at 1 year after the index procedure. Subjects were divided into 2 groups: DAPT&gt;1-year group (n=5252) and DAPT≤1-year group (n=2269). Patients at high-risk for ischemic or bleeding events were defined as having at least one additional clinical feature and one angiographic feature according to TWILIGHT trial criteria. The clinical criteria for high risk were age≥65 years, female sex, troponin-positive ACS, established vascular disease, diabetes mellitus that was being treated with medication, and CKD. Angiographic criteria included multivessel coronary artery disease, total stent lengthd≥30 mm, a thrombotic target lesion, a bifurcation lesion treated with two stents, an obstructive left main or proximal left anterior descending lesion, and a calcified target lesion treated with atherectomy. The primary outcome was major adverse cardiac and cerebrovascular events [MACCE] (a composite of all-cause death, MI, or stroke).

Results

During a median follow-up of 30 months after the index procedure, DAPT&gt;1-year was associated with a reduction in risk for MACCE compared with DAPT≤1-year (1.5% vs. 3.8%; adjusted hazard ratio [HR]: 0.36; 95% confidence interval [CI]: 0.27–0.50; P&lt;0.001) after multivariable adjustment. This difference was largely driven by a lower risk of all-cause mortality. In contrast, the risk of BARC type 2, 3 or 5 bleeding was statistically similar between the 2 groups (1.0% vs. 1.1%; adjusted HR: 0.81; 95% CI: 0.50–1.30; P=0.373). After propensity score matching, incidence of MACCE was still lower in the DAPT&gt;1-year group than the DAPT≤1-year group (1.6% versus 4.5%; HR, 0.34; 95% CI, 0.22–0.52; P&lt;0.001) and the rates of BARC type 2, 3 or 5 bleeding was not different between the 2 groups (1.1% versus 0.9%; adjusted HR, 1.12; 95% CI, 0.57–2.18; P=0.744). In subgroup analysis, the treatment effect of prolonged DAPT was consistent across subgroups regardless of ACS, DAPT score, or type of used DES.

Conclusions

DAPT continuation with aspirin and clopidogrel beyond 1-year after DES implantation resulted in a significantly lower rate of MACCE, with no higher risk of clinically relevant bleeding in patients who were at high-risk for ischemic or bleeding events.

Chinese public's knowledge, perceived severity, and perceived controllability of COVID-19 and their associations with emotional and behavioural reactions, social participation, and precautionary behaviour: a national survey

BACKGROUND

The outbreak of the coronavirus disease-19 (COVID-19) has caused enormous stress among the public in China. Intellectual input from various aspects is needed to fight against COVID-19, including understanding of the public's emotion and behaviour and their antecedents from the psychological perspectives. Drawing upon the cognitive appraisal theory, this study examined three cognitive appraisals (i.e., perceived severity, perceived controllability, and knowledge of COVID-19) and their associations with a wide range of emotional and behavioural outcomes among the Chinese public.

METHODS

Participants were 4607 citizens (age range: 17-90 years, Mage = 23.71 years) from 31 provinces in China and they took part in a cross-sectional survey online.

RESULTS

The results showed that the public's emotional and behavioural reactions were slightly affected by the outbreak of COVID-19. Moreover, the public had limited participation in the events regarding COVID-19 but actively engaged in precautionary behaviour. In addition, results of structural equation model with latent variables revealed that the three appraisals were differentially related to the outcome variables (i.e., negative emotion, positive emotion, sleep problems, aggression, substance use, mobile phone use, social participation, and precautionary behaviour).

CONCLUSIONS

The findings highlight the utility of cognitive appraisal, as a core process of coping stress, in explaining the public's emotion and behaviour in the encounter of public health concern. Practically, the findings facilitate the government and practitioners to design and deliver targeted intervention programs to the public.

Extracurricular sports participation increases life satisfaction among Chinese adolescents: A moderated mediation model

We investigated whether participation in extracurricular sports promotes the life satisfaction of Chinese adolescents and tested the mediating effect of academic stress and the moderating effect of extraversion in this relationship. We conducted a survey with 1,608 Chinese adolescents to assess their participation in extracurricular sports and their levels of extraversion, academic stress, and life satisfaction. The regression analysis results indicate that extracurricular sports participation positively influenced life satisfaction through the mediator of academic stress. The moderated regression analysis results reveal that high extraversion strengthened not only the direct effects of extracurricular sports participation and academic stress but also the indirect effects of extracurricular sports participation and life satisfaction. These findings indicate that participation in extracurricular sports chiefly promoted life satisfaction in Chinese adolescents indirectly by reducing their academic stress, subject to the moderating effect of having an extraverted personality. Thus, increasing the time students spend on participating in extracurricular sports can help to enhance their life satisfaction.

Mobile Phone Addiction and Risk-Taking Behavior among Chinese Adolescents: A Moderated Mediation Model

Objectives: The mobile phone (MP) is an indispensable digital device in adolescents’ daily lives in the contemporary era, but being addicted to MP can lead to more risk-taking behavior. However, little is known about the mediating and moderating mechanisms underlying this relation. To address the gaps in the literature, the present study examined the idea that MP addiction is associated with reduced self-control, which further associates with increased risk-taking behavior. In addition, this study also investigated the moderation effect of adolescent sex in the association between MP addiction and self-control. Methods: A three-wave longitudinal study, each wave spanning six months apart, was conducted in a sample of Chinese adolescents (final N = 333, 57.4% girls). Results: Results of the moderated mediation model suggest that after controlling for demographic variables and baseline levels of self-control and risk-taking behavior, MP addiction at T1 positively predicted increased risk-taking behavior at T3 through reduced self-control at T2 for girls but not for boys. Conclusions: Theoretically, these findings contribute to the understanding about the working processes in the association between MP addiction and risk-taking behavior in adolescents. Practically, the results implied that boosting self-control appeared as a promising way to reduce girls’ risk-taking behavior, particularly for those who are addicted to MPs.

Self-Control Moderates the Association Between Perceived Severity of Coronavirus Disease 2019 (COVID-19) and Mental Health Problems Among the Chinese Public

Coronavirus disease 2019 (COVID-19) has caused thousands of deaths in China. Prior research suggests that individuals' perceived severity of COVID-19 is related to a range of negative emotional and behavioral reactions among the Chinese public. However, scant research has examined the underlying mechanisms. Drawing upon the risk-resilience model, this study proposes that self-control, as a resilient factor, would potentially moderate the association between perceived severity of COVID-19 and mental health problems. Data from a national survey was used to examine this idea. Participants were 4607 citizens from 31 regions in China (Mage = 23.71 years, 72.5% female) who completed a national survey at the beginning of February 2020. Results of hierarchical regression showed that after controlling for a number of demographic variables, perceived severity of COVID-19 and self-control were positively and negatively related to mental health problems, respectively. More importantly, self-control moderated the "perceived severity of COVID-19-mental health problems" association, with this link attenuating as the levels of self-control increased. These findings suggest that compared to those with high self-control, individuals with low self-control are more vulnerable and are more in need of psychological aids to maintain mental health in the encounter of the COVID-19 outbreak. Practically, enhancing individuals' self-control ability might be a promising way to improve individuals' mental health during the early period of the COVID-19 outbreak.

Elicitor hydrophobin Hyd1 interacts with Ubiquilin1-like to induce maize systemic resistance

Trichoderma harzianum is a plant-beneficial fungus that secretes small cysteine-rich proteins that induce plant defense responses; however, the molecular mechanism involved in this induction is largely unknown. Here, we report that the class II hydrophobin ThHyd1 acts as an elicitor of induced systemic resistance (ISR) in plants. Immunogold labeling and immunofluorescence revealed ThHyd1 localized on maize (Zea mays) root cell plasma membranes. To identify host plant protein interactors of Hyd1, we screened a maize B73 root cDNA library. ThHyd1 interacted directly with ubiquilin 1-like (UBL). Furthermore, the N-terminal fragment of UBL was primarily responsible for binding with Hyd1 and the eight-cysteine amino acid of Hyd1 participated in the protein-protein interactions. Hyd1 from T. harzianum (Thhyd1) and ubl from maize were co-expressed in Arabidopsis thaliana, they synergistically promoted plant resistance against Botrytis cinerea. RNA-sequencing analysis of global gene expression in maize leaves 24 h after spraying with Curvularia lunata spore suspension showed that Thhyd1-induced systemic resistance was primarily associated with brassinosteroid signaling, likely mediated through BAK1. Jasmonate/ethylene (JA/ET) signaling was also involved to some extent in this response. Our results suggest that the Hyd1-UBL axis might play a key role in inducing systemic resistance as a result of Trichoderma-plant interactions.

Career-related parental behaviors, adolescents' consideration of future consequences, and career adaptability: A three-wave longitudinal study

Career adaptability is a critical psychological resource for adolescents during their transition from secondary to postsecondary education. Based on prospective data from 451 Chinese adolescents (M = 16.87, SD = 0.63; 46.3% female), this study examined the mediating role of adolescents' consideration of future consequences (CFCS) in the association between career-related parental behaviors and adolescents' career adaptability. Results demonstrated that career-related parental support at Wave 1 was associated positively with adolescents' career adaptability and its subdimensions (i.e., career concern, control, curiosity, and confidence) at Wave 3 (i.e., 10 months later). Adolescents' CFCS at Wave 2 (i.e., 5 months later after Wave 1) served as a mediator linking career-related parental support at Wave 1 and career concern, control, and curiosity, but not confidence at Wave 3. Neither parental lack of engagement nor interference at Wave 1 predicted adolescents' career adaptability at Wave 3. These results suggest that interventions assisting parents in performing supportive behaviors, such as engaging in adolescents' career exploration activities and offering information about various kinds of jobs, might be useful strategies to foster adolescents' curiosity and confidence in choosing future career paths. Additionally, counselors and parents may offer adolescents strategies to strengthen their abilities to consider the potential influences of their current behaviors on future career paths (e.g., prioritizing behaviors and activities related to their future career paths over activities that only provide immediate or short-term gratification) to promote their capabilities of coping with challenges during the career transition period.

Engaging in prosocial behavior explains how high self-control relates to more life satisfaction: Evidence from three Chinese samples

High levels of self-control are found to be associated with greater life satisfaction. To further understand this relationship, the current study examined two questions: (1) whether too much self-control reduces, rather than increases, life satisfaction, as argued by some scholars; and (2) whether engaging in prosocial behavior explains the "self-control-life satisfaction" link. To this end, we conducted survey research among adolescents (N = 1,009), university students (N = 2,620), and adult workers (N = 500). All participants answered the same self-control and life satisfaction measures, whereas prosocial behavior was assessed using different scales across samples. Results of two-line regressions failed to reveal significant inverted-U shaped association between self-control and life satisfaction across samples. Moreover, results of mediation analyses showed that across samples, high levels of self-control were related to greater life satisfaction and this association was partly mediated by prosocial behavior. In conclusion, there is no evidence showing that too much self-control impairs life satisfaction. Engaging in prosocial behavior partly explains how high self-control relates to greater well-being.

Exposure to Community Violence, Affiliations With Risk-Taking Peer Groups, and Internet Gaming Disorder Among Chinese Adolescents: The Moderating Role of Parental Monitoring

Among adolescents, exposure to community violence (ECV) has been consistently linked to problem behaviors such as Internet gaming disorder (IGD). However, the associated risk and protective factors have not been adequately explored in past studies. Therefore, in accordance with the risk-buffering model and social development model, this study aimed to test whether parental monitoring moderated the relationship between ECV and IGD among adolescents, and whether this moderating effect was mediated by affiliations with risk-taking peer groups. A sample of 2,423 Chinese middle-school students anonymously responded to questionnaires that assessed ECV, IGD, affiliations with risk-taking peer groups, and parental monitoring. The results of structural equation modeling revealed that the interaction between ECV and parental monitoring negatively related to IGD among adolescents. Specifically, the positive relationship between ECV and IGD was stronger for adolescents, who reported low levels of parental monitoring than for those who reported high levels of parental monitoring. Moreover, this moderating effect was mediated by affiliations with risk-taking peer groups. These results suggest that parental monitoring is an important protective factor that can mitigate the risk of IGD among adolescents who have been exposed to community violence. Accordingly, these findings serve as an empirical base upon which prevention and intervention strategies that are aimed at mitigating the risk of IGD among adolescents can be developed.

Why Awe Promotes Prosocial Behaviors? The Mediating Effects of Future Time Perspective and Self-Transcendence Meaning of Life

Awe is an emotion experience when individuals encounter with such powerful stimulate beyond their own understanding. Guided by conceptual analysis of awe as a trait positive emotion, we tested the hypothesis that dispositional awe results in an improvement of individual's self-transcendence meaning of life (STML) and affects future time perspective, and increase prosocial behavior. Mediational data demonstrate that the effects of awe on prosociality are explained, by improving STML self and future time perspective. These findings indicate that awe may help situate individuals within broader social contexts and enhance collective concern.

School Climate, Loneliness, and Problematic Online Game Use Among Chinese Adolescents: The Moderating Effect of Intentional Self-Regulation

Evidently, the school climate is important in reducing adolescent problematic online game use (POGU); however, the mechanism accounting for this association remains largely unknown. This study examined whether loneliness mediated the link between school climate and adolescent POGU and whether this mediating process was moderated by adolescent intentional self-regulation. To this end, self-report questionnaires were distributed. Participants were 500 12–17-years-old Chinese adolescents (Mean_age = 13.59 years, 50.60% male). After controlling for adolescents' gender, age, family socioeconomic status, and self-esteem, the results showed that the negative association between school climate and adolescent POGU was partially mediated by loneliness. Moreover, this indirect link was stronger for adolescents with low intentional self-regulation than for those with high intentional self-regulation. These findings highlight loneliness as a potential mechanism linking school climate to adolescent POGU and provide guidance for the development of effective interventions for addressing the adverse effects of a negative school climate.

Is individualism-collectivism associated with self-control? Evidence from Chinese and U.S. samples

Self-control plays an important role in human’s daily life. In the recent two decades, scholars have exerted tremendous effort to examine the etiologies of the individual differences in self-control. Among numerous predictors of self-control, the role of culture has been relatively overlooked. In this study, the influences of cultural orientation on self-control were examined based on the collectivism-individualism framework using both self-report and behavioral task to assess self-control. A convenience sample of 542 Chinese and 446 U.S. undergraduates participated in the research. They were invited to fill out self-report questionnaires reporting their levels of attitudinal self-control and individualistic-collectivistic orientation after completing a computer-based Stroop task. Results of hierarchical regression models showed that Chinese participants reported less attitudinal self-control but had higher behavioral self-control than their U.S. counterparts. Moreover, individual-level individualism and collectivism was negatively and positively related to attitudinal self-control in both countries, respectively. Individual-level collectivism was significantly related to better behavioral self-control, but no significant results were found for the relationship between individual-level individualism and behavioral self-control. In sum, individualism and collectivism have some influences on individual differences in self-control. Implications for future research were discussed.

Co-culture of Bacillus amyloliquefaciens ACCC11060 and Trichoderma asperellum GDFS1009 enhanced pathogen-inhibition and amino acid yield

Background

Bacillus spp. are a genus of biocontrol bacteria widely used for antibiosis, while Trichoderma spp. are biocontrol fungi that are abundantly explored. In this study, a liquid co-cultivation of these two organisms was tried firstly.

Results and discussion

Through liquid chromatography-mass spectrometry/mass spectrometry (LC–MS/MS), it was discovered that with an inoculation in the ratio of 1.9:1, the antimicrobial effect of the co-cultured fermentation liquor of Bacillus amyloliquefaciens ACCC11060 and Trichoderma asperellum GDFS1009 was found to be significantly higher than that of pure-cultivation. A raise in the synthesis of antimicrobial substances contributed to this significant increase. Additionally, a co-culture with the inoculation of the two organisms in the ratio of 1:1 was found to enhance the production of specific amino acids. This technique could be further explored for either a large scale production of amino acids or could serve as a theoretical base for the generation of certain rare amino acids.

Conclusions

This work clearly demonstrated that co-cultivation of B. amyloliquefaciens ACCC11060 and T. asperellum GDFS1009 could produce more specific biocontrol substances and amino acids.

Why and when does job satisfaction promote unethical pro-organizational behaviours? Testing a moderated mediation model

This study examined the relationship between job satisfaction and unethical pro-organizational behaviours (UPB) by testing a moderated mediation model that focused on how employees' belongingness mediates the relationship between job satisfaction and UPB and how corporate ethical values moderate this mediated relationship. Our investigation included 369 employees from different organizations in Southeast China. The regression analysis revealed that job satisfaction positively influences UPB through belongingness. In addition, a moderated regression analysis indicated that low corporate ethical values strengthen not only the effect of belongingness on UPB but also the indirect effect of job satisfaction on UPB. These findings deepen our understanding of UPB by showing that individuals with a high level of job satisfaction are more likely to engage in UPB through belongingness when corporate ethical values are low. Finally, the theoretical and managerial implications of these results are discussed.

The relationship between trait self-control, consideration for future consequence and organizational citizenship behavior among Chinese employees

BACKGROUND

Organizational citizenship behavior (OCB) is important to the development of an organization. Research into factors that foster OCB and the underlying processes are therefore substantially crucial.

OBJECTIVE

The current study aimed to test the association between trait self-control and OCB and the mediating role of consideration for future consequence.

METHOD

Four hundred and ninety-four Chinese employees (275 men, 219 women) took part in the study. Participants completed a battery of self-report measures online that assessed trait self-control, tendencies of consideration of future consequence, and organizational citizenship behavior. Path analysis was conducted and bootstrapping technique (N = 5000), a resampling method that is asymptotically more accurate than the standard intervals using sample variance and assumptions of normality, was used to judge the significance of the mediation.

RESULTS

Results of path analysis showed that trait self-control was positively related to OCB. More importantly, the "trait self-control-OCB" link was mediated by consideration of future consequence-future, but not by consideration of future consequence-immediate.

CONCLUSIONS

Employees with high trait self-control engage in more organizational citizenship behavior and this link can be partly explained by consideration of future consequence-future.

Impact of cognitive flexibility on rapid reading skills training outcomes for primary school students in China

This study used a quasi-experimental design to investigate the impact of Rapid Reading Skills Training (RRST) on some reading outcomes for primary school students in central China and also examined the influence of cognitive flexibility on intervention outcomes. A sample of 108 students (mean age = 11.75 years) were recruited. Students' cognitive flexibility was measured with the Wisconsin Card Sorting Task. Cluster randomization was used to assign students at the whole class level to either an experimental or control condition. A 12-session RRST intervention was completed with the experimental class ( N = 54). Silent reading speed and passage comprehension were measured before and after training for all students. Independent samples t-tests and two-factor repeated measures ANOVA revealed that students in the experimental class displayed higher scores for reading speed and effective reading rate post-intervention than those in the control class. Students who had scored higher on cognitive flexibility showed significantly larger increases post-intervention than those scored lower. Results provide preliminary support for using RRST to increase rapid silent reading speed among Chinese primary school students, though replication and more rigorous experimental designs are needed. Cognitive flexibility may enhance gains associated with this type of intervention. Implications for school psychologists are discussed.
