Task complexity,student perceptions of vocabulary learning in EFL,and task performance

Background. The study deepened our understanding of how students’ self‐efficacy beliefs contribute to the context of teaching English as a foreign language in the framework of cognitive mediational paradigm at a fine‐tuned task‐specific level. Aim. The aim was to examine the relationship among task complexity, self‐efficacy beliefs, domain‐related prior knowledge, learning strategy use, and task performance as they were applied to English vocabulary learning from reading tasks. Sample. Participants were 120 second‐year university students (mean age 21) from a Chinese university. Method. This experiment had two conditions (simple/complex). A vocabulary level test was first conducted to measure participants’ prior knowledge of English vocabulary. Participants were then randomly assigned to one of the learning tasks. Participants were administered task booklets together with the self‐efficacy scales, measures of learning strategy use, and post‐tests. Data obtained were submitted to multivariate analysis of variance (MANOVA) and path analysis. Results. Results from the MANOVA model showed a significant effect of vocabulary level on self‐efficacy beliefs, learning strategy use, and task performance. Task complexity showed no significant effect; however, an interaction effect between vocabulary level and task complexity emerged. Results from the path analysis showed self‐efficacy beliefs had an indirect effect on performance. Our results highlighted the mediating role of self‐efficacy beliefs and learning strategy use. Conclusions. Our findings indicate that students’ prior knowledge plays a crucial role on both self‐efficacy beliefs and task performance, and the predictive power of self‐efficacy on task performance may lie in its association with learning strategy use.     

Abusive supervision and subordinate emotional labor: The moderating role of openness personality

We investigated the differential relationships between abusive supervision and two emotional labor strategies used by subordinates (surface acting and deep acting). Furthermore, we examined whether subordinates' openness personality moderated the above relationships. Using the questionnaire survey method, we collected data from 210 employees in China. The results of hierarchical regression showed that abusive supervision related positively to surface acting (regulating facial expression) but negatively to deep acting (regulating inner feeling). Openness personality moderated the relationships between abusive supervision and the two emotional labor strategies, such that the relationships were stronger for employees with lower openness. Findings of our study contribute to the literature on workplace emotions and negative leadership.     

程度函数及其可靠性

通过实验及理论分析,验证并给出了：１．程度函数ａ的可靠性θ的取值范围为：１／ｍ≤θ≤１／ｍ∑ｂｋｙｊｐ。θ值的大小与可靠性呈反向变化：ａ的可靠性大,θ值小,ａ的可靠性小θ值大,一般情况下的θ值,为θ的上界与下界之和的一半;２．采用集值统计模型和一般统计模型处理多级估量法多人次结果,所得到的程度函数平均数几乎相等,而且相关系数高达０．９７７．非常显著．分组数据计算、单一数据计算或全部数据统一计算的程度函数ａ及可靠性θ值也都相等．３．一般统计模型处理多级估量法多人次结果所得到的标准差σ,只反映各被试的程度函数之间的变异,与程度函数可靠性无关（相关系数０．００２４,非常不显著）．如果个人结果中按公式θ＝１／ｍ∑ｅｊ再计算可靠性θ值,然后再求其平均数及标准差,还可进一步了解可靠性θ值的变异情况．     

Microstructure and martensitic transformation behaviors of a Ti–Ni–Hf–Cu high-temperature shape memory alloy ribbon

The Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon undergoes a B2 ? B19′ transformation upon cooling and heating. When the Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon is annealed at 873 K for 1 h, the spherical (Ti, Hf)₂Ni particles with a diameter of 20–40 nm precipitate in the grain interior. The fine (Ti, Hf)₂Ni precipitates improve the stability of phase transformation temperatures and cause martensite domains, with (001) compound twins in three orientations dominant instead of (011) type I twins. {111}-, {113}- and (001)//{111}-type boundaries are observed among these martensite domains. When the (Ti,Hf)₂Ni precipitates coarsen, (011) type I twins become main martensite structures in the ribbon annealed at 973 K for 1 h.     

A novel lattice correspondence of B19 → B19′ transformation in Ti–Ni–Cu shape memory alloy thin film

In this study, we found a novel lattice correspondence of the B19–B19′ transformation in a Ti–Ni–Cu thin film: (1?1?1)_B19′//(0?0?1)_B19, [0, 1, 1]_B19′//[1?0?0]_B19. Near the coarse precipitate and the grain boundaries, the B19′ martensite forms with the novel lattice correspondence to product the (1?1?1) type I twinning instead of the usual (0?0?1) compound twinning. Crystallographic analyses show that the novel lattice correspondence results from the local stress concentration.     

Mindfulness and spirituality as predictors of personal maturity beyond the influence of personality traits

Historically, the concept of human maturity has been discussed in the social science field. The process of attaining maturity has also been explored since last century. This study investigates the possible influences of mindfulness practice and spirituality in predicting maturity. The model of causes of maturity in this study assesses the contributions of personality, mindfulness, and spirituality in the prediction of maturity in a random sample of 537 Chinese adults. Results indicated that personality, mindfulness, and spirituality all correlated with maturity in many aspects. Multiple regression analyses found that mindfulness and spirituality each added an additional significant amount of variance in maturity after controlling for the influence of age and personality. As expected, when mindfulness and spirituality were practiced together, the amount of combined incremental influence on maturity was significantly greater than the amounts of incremental influence mindfulness and spirituality each alone had on maturity.     

Be Happy,don't Wait: The Role of Trait Affect in Job Search

In this study we developed and tested a self‐regulatory model of trait affect in job search. Specifically, we theorized that trait positive and negative affect would influence both motivation control and procrastination, and these mediating variables would, in turn, influence job search outcomes through job search intensity. Using longitudinal data from 245 graduating students who were searching for a full‐time position, we found that positive, but not negative, affect influenced the self‐regulatory variables of motivation control and procrastination, which in turn influenced the job search outcomes. Procrastination had direct effects on the number of first interviews, controlling for job search intensity, and on the number of second interviews, controlling for first interviews, suggesting the importance of timeliness of job search activities. We discuss the implications of such results for understanding the role of affect and self‐regulation in the job search process and for measuring the quality as well as quantity (i.e., intensity) of job search tactics.     

A New Procedure to Test Mediation With Missing Data Through Nonparametric Bootstrapping and Multiple Imputation

This article proposes a new procedure to test mediation with the presence of missing data by combining nonparametric bootstrapping with multiple imputation (MI). This procedure performs MI first and then bootstrapping for each imputed data set. The proposed procedure is more computationally efficient than the procedure that performs bootstrapping first and then MI for each bootstrap sample. The validity of the procedure is evaluated using a simulation study under different sample size, missing data mechanism, missing data proportion, and shape of distribution conditions. The result suggests that the proposed procedure performs comparably to the procedure that combines bootstrapping with full information maximum likelihood under most conditions. However, caution needs to be taken when using this procedure to handle missing not-at-random or nonnormal data.     

The dissemination and research of Laszlo's systems philosophy in China

Since the 1980s, the so‐called “new six‐theory” (Dissipative structure theory, Synergetics theory, Catastrophe theory, Chaos theory, Fractal theory, and Hypercycle theory), different from the traditional “systems theory,” “information theory,” and “cybernetics theory” (the “old three theory") has been introduced into China. With it, Laszlo's systems philosophy has been given close attention by Chinese scholars. The main elements of this work are analyzed in terms of the publication and research of Laszlo's work on systems philosophy, and more specifically on systems philosophy and the theory of knowledge, systems philosophy and general evolution theory, systems philosophy and the theory of value, and systems philosophy and metaphysics.
