Effect of metastable Cr(Mo)s/Cr(Mo)a powders on mechanical alloying the immiscible Cu–Mo–Cr system

Metastable-state alloy powders are usually synthesised by milling and occur as products of mechanical alloying (MA), but they are rarely used as starting materials for other MA processes. In this work, metastable-state alloy powders, including supersaturated solid-solution Cr(Mo)s and amorphous Cr(Mo)a were prepared in advance. Then, the Cr(Mo)s/Cr(Mo)a powder mixture was mechanically alloyed with elemental Cu to form Cu–Mo–Cr alloy. The effects of the metastable-state powder Cr(Mo)s/Cr(Mo)a on MA of the immiscible Cu–Mo–Cr system were evaluated. Phases and microstructures of the milled powders were analysed by XRD and TEM, respectively. The results show that amorphous Cu-60wt.%Cr(Mo) and supersaturated solid-solution Cu-20wt.%Cr(Mo) alloy powders can be synthesised by MA. It is concluded that MA of the Cu–Mo–Cr ternary alloy system is significantly promoted when elemental Cu powder is milled with metastable-state alloy powder Cr(Mo)s/Cr(Mo)a. Furthermore, the promoting effect of amorphous Cr(Mo)a on MA the Cu–Mo–Cr alloy system is much greater than that of supersaturated solid-solution Cr(Mo)s, during the milling process.     

Cognitive Diagnosis for Small Educational Programs: The General Nonparametric Classification Method

The focus of cognitive diagnosis (CD) is on evaluating an examinee’s strengths and weaknesses in terms of cognitive skills learned and skills that need study. Current methods for fitting CD models (CDMs) work well for large-scale assessments, where the data of hundreds or thousands of examinees are available. However, the development of CD-based assessment tools that can be used in small-scale test settings, say, for monitoring the instruction and learning process at the classroom level has not kept up with the rapid pace at which research and development proceeded for large-scale assessments. The main reason is that the sample sizes of the small-scale test settings are simply too small to guarantee the reliable estimation of item parameters and examinees’ proficiency class membership. In this article, a general nonparametric classification (GNPC) method that allows for assigning examinees to the correct proficiency classes with a high rate when sample sizes are at the classroom level is proposed as an extension of the nonparametric classification (NPC) method (Chiu and Douglas in J Classif 30:225–250, 2013). The proposed method remedies the shortcomings of the NPC method and can accommodate any CDM. The theoretical justification and the empirical studies are presented based on the saturated general CDMs, supporting the legitimacy of using the GNPC method with any CDM. The results from the simulation studies and real data analysis show that the GNPC method outperforms the general CDMs when samples are small.     

The anchoring effect in metamemory monitoring

Judgments about future memory performance (metamemory judgments) are known to be susceptible to illusions and bias. Here we asked whether metamemory judgments are affected, like many other forms of judgment, by numerical anchors. Experiment 1 confirmed previous research showing an effect of informative anchors (e.g., past peer performance) on metamemory monitoring. In four further experiments, we then explored the effects of uninformative anchors. All of the experiments obtained significant anchoring effects on metamemory monitoring; in contrast, the anchors had no effect on recall itself. We also explored the anchoring effect on metamemory control (restudy choices) in Experiment 4. The results suggested that anchors can affect metamemory monitoring, which in turn affects metamemory control. The present research reveals that informative and, more importantly, uninformative numbers that have no influence on recall itself can bias metamemory judgments. On the basis of the current theoretical understanding of the anchoring effect and metamemory monitoring, these results offer insight into the processes that trigger metacognitive biases.     

进化心理学视角中的腐败行为及心理机制

腐败作为全世界普遍关注的焦点问题,不同领域学者针对腐败行为产生原因与对策进行探讨。普遍认为制度、权力、文化等因素是腐败行为产生的重要原因,个别研究涉及到腐败主体的内在心理。进化心理学从进化和适应的视角对人类行为发生及心理内在特征具有终极解释度。因此,本文在前人研究的基础上,基于进化心理学的独特视角,从个体生命史历程(如童年创伤、贫穷经历等)去揭示腐败行为产生的心理机制。     

Parental Rearing Behaviors and Adolescent’s Social Trust: Roles of Adolescent Self-esteem and Class Justice Climate

Research on the antecedents and underlying mechanisms of the formation of adolescent social trust is scant. Family and school are two major environments in which adolescents become socialized. The current study examined the effect of parental rearing behaviors (rejection, emotional warmth and overprotection) on adolescent social trust, exploring the mediating role of adolescent self-esteem and the multilevel moderated role of the Level 2 variable class justice climate. The sample included 612 (12–16 years old) middle school students in China. Participants completed the s-EMBU, the Rosenberg Self-esteem Scale, Rosenberg’s Faith in People Scale and the perceptions of class justice scale, along with other control variables. The results suggested that parental rearing behaviors significantly predicted adolescent social trust, regardless of adolescent gender or age. Additional mediation analysis suggested that parental rearing behaviors had both direct effects on adolescent social trust and indirect effects through adolescent self-esteem. Further multilevel structural equation modeling indicated that class justice climate moderated the effect of parental rejection on adolescent self-esteem. The findings suggest that family and school practice jointly shape adolescents’ social trust. How parents treat their children has a huge influence on the degree to which their children trust other people. In addition, perceived class justice could buffer the harmfulness of negative parental rearing behaviors.     

Psychological distress in patients with chronic atrophic gastritis: the risk factors,protection factors,and cumulative effect

This study aimed to examine the psychological status among Chronic Atrophic Gastritis (CAG) patients and to find the cumulative effects of risk and protective factors. A sample of 101 CAG patients completed the investigation. Hierarchical linear regression was used to find risk and protective factors, and examine the cumulative effects in risk factor index (RFI) and protective factor index (PFI). Results showed that nine symptoms from SCL-90-R were severer among CAG patients than those in adult norm. Risk factors including positive family history of cancer and higher negative life events could predict higher GSI (β = 0.206, p = 0.023; β = 0.398, p < 0.001; R² = 0.203); more household resistant, positive coping and stronger resilience were protective factors and could predict GSI negatively (β = -0.188, p = 0.020; β = -0.350, p = 0.012; β = ?0.066, p = 0.621; R² = 0.190). The GSI was positively correlated with RFI (β = 0.338, p < 0.001; R² = 0.113) and negatively related to PFI (β = ?0.378, p < 0.001; R² = 0.133). In conclusion, CAG patients suffered from various psychological distress, and the protective factors should be enhanced cumulatively to protect against psychological distress.     

“Pain is forgotten where gain follows:” The masking effect of positive outcomes on emotional suffering

Previous research has shown that people tend to overstate or understate their past feelings in memory when asked to recall their past emotional experiences. Drawing from cognitive reappraisal theory and mood congruence theory, we presented an integrative explanation that the type of outcome of stressful events influences the magnitude and direction of bias in emotional memory. The results of two studies showed that individuals who succeeded in a postgraduate recruitment interview or a job interview tended to overstate positive emotions and understate negative emotions. In contrast, individuals who failed in an interview understated positive emotions and overstated negative emotions. This phenomenon can be named “pain is forgotten where gain follows.” These results shed light on the controversy between mood congruent theory and the appraisal model as well as application values in intervention research on emotional biases.     

Age-related differences in affective and cognitive empathy: self-report and performance-based evidence

The correlation between age and empathy is not clear, with prior findings yielding mixed and inconsistent results. Here, we distinguished between two aspects of empathy and respectively investigated the effects of age on the affective and cognitive facets of empathy using a self-report measure (interpersonal reactivity index, IRI) and performance-based tasks (viewing films). The results showed that older adults manifested age-related deficits in both trait and state cognitive empathy, with the latter being positively associated with memory. Otherwise, the overall affective empathy increased in the elderly, but the age-related differences in affective empathy may be qualified by the valence of the film clips. Specifically, older participants showed more empathic concern (EC) and less personal distress (PD) to other people’s emotions than the younger participants for the distress film. Interestingly, for the amusing film, older participants demonstrated more EC and PD. Overall, the two aspects of empathy have different development trajectories.
