The directional solidification process of ternary Ag42.4Cu21.6Sb36 eutectic alloy within a wide growth rate range from 2 to 60 μm/s was accomplished at a constant temperature gradient of 50 K/cm. As growth rate increases, the ternary (θ(Cu2Sb) + ε(Ag3Sb) + Sb) eutectic morphology evolves from “lamellar (θ + ε) plus fibrous (Sb)” structure into “(θ + Sb) fibres in continuous ε matrix” structure. The θ and (Sb) phase spacings decrease with the increase of growth rate according to power functions with exponent values of 0.55 and 0.56, respectively. It is also found that the microhardness of directionally solidified Ag42.4Cu21.6Sb36 alloy samples is enhanced with the increase of growth rate, and the decrease of θ and (Sb) phase spacings.  相似文献

"道"是老子哲学体系中的核心,老子不仅提出虚空的道是宇宙的本体,是无法用语言来描述的,而且说明道是混成之物,即道是有精妙的内部结构属性的,并从不同的侧面说明了认识"道"是混成之物的路径。道是由无限创生因子混融而成的系统,宇宙在创生及万物演化的过程中,道或无限的创生因子始终起着根本性的作用,即宇宙间的一切事物现象都是道所为。道是由创生因子混融而成的思想观点,可为现代宇宙论的发展提供新的思维维度,为科学探索真空世界的奥秘提供新的研究途径,推进现代宇宙学的进步。  相似文献

在19世纪70~90年代的中国,当指称"mental philosophy"与"psychology"时,译者主要使用了"性学"、"心理(学)"、"性理(学)"、"心才学"、"心灵学"和"心学"等6个名称。据现有史料,尽管汉语"心理学"一词由执权居士于1872年首译,但当时并未受到中国学人的重视。现在通行的汉语"心理学"一词是来自日本人西周,经康有为与梁启超等人的共同努力才逐渐被中国人所接受,并于1902年以后被普遍使用。汉语"心理学"一词在这场"比赛"中能够最终胜出,内因是既受中国文化传统和思维方式的影响,又为避免将一门新兴学科等同于旧学科从而产生"新瓶装旧酒"的误会;外因是中国新学科体系在创建时深受日本和西方国家的影响。  相似文献

基于社会控制理论,运用问卷调查法,通过分析308组配对数据,探讨工具主义伦理气氛对员工沉默行为的影响机制。结果发现:工具主义伦理气氛对沉默行为有正向作用;工具主义伦理气氛对犬儒主义有正向作用;犬儒主义在工具主义伦理气氛与沉默行为之间起部分中介作用;传统性调节了犬儒主义与沉默行为的关系,也调节了犬儒主义在工具主义伦理气氛与沉默行为关系的中介作用。  相似文献

为探索希望在父母与学前儿童之间的代际传递效应,以及父母教养方式在其中的中介作用,使用成人特质希望量表、儿童希望量表(他评版)及教养方式问卷对1034名学前儿童的家长进行了调查。结果表明,父母希望显著正向预测儿童希望,教养方式在其中起部分中介作用,且这一中介模型对于父亲和母亲完全等价。说明希望存在代际传递性;希望水平高的父母更倾向于采取积极的教养方式,进而提升学前儿童的希望水平;并且父亲和母亲以相同的模式将希望通过教养方式的中介作用传递给儿童。  相似文献

Multifaceted data are very common in the human sciences. For example, test takers' responses to essay items are marked by raters. If multifaceted data are analyzed with standard facets models, it is assumed there is no interaction between facets. In reality, an interaction between facets can occur, referred to as differential facet functioning. A special case of differential facet functioning is the interaction between ratees and raters, referred to as differential rater functioning (DRF). In existing DRF studies, the group membership of ratees is known, such as gender or ethnicity. However, DRF may occur when the group membership is unknown (latent) and thus has to be estimated from data. To solve this problem, in this study, we developed a new mixture facets model to assess DRF when the group membership is latent and we provided two empirical examples to demonstrate its applications. A series of simulations were also conducted to evaluate the performance of the new model in the DRF assessment in the Bayesian framework. Results supported the use of the mixture facets model because all parameters were recovered fairly well, and the more data there were, the better the parameter recovery.  相似文献

This study tested whether the presence of an attractive face would influence individuals' honesty. In 2 experiments, 225 participants were asked to predict the outcome of computerised coin‐flips and to self‐report the accuracy of their predictions. Self‐reports were made in the presence of a facial photo of a female who had been rated before the experiment as high attractive, middle attractive or low attractive by other volunteers. Participants were rewarded based on their self‐reported (not actual) accuracy. The results showed that subjects tended to give more dishonest self‐reports when presented with middle or low attractive facial images than when presented with high attractive images, with self‐reported accuracy being significantly higher than the random level. The results of this study show that presented with an attractive face, subjects tend to engage in behaviours that conform to moral codes.  相似文献

Based on career construction theory and the model of proactive motivation, the current research examined the mediating and moderating models for the relations among future work self, career adaptability, job search self-efficacy and employment status. A survey study was conducted among Chinese university graduates (N = 270). The results showed that future work self (measured at wave 1) had positive effect on employment status (measured at wave 3), with this relationship partially mediated by career adaptability (measured at wave 1) and job search self-efficacy (measured at wave 2). In addition, the results further revealed that the positive effect of future work self on job search self-efficacy was stronger among the graduates who had a higher level of career adaptability. In support of the hypothesized moderated mediation model, for individuals with a higher level of career adaptability, the indirect effect of future work self on employment status through job search self-efficacy was stronger. These findings carry implications for research on job search behavior, career education and career counseling.  相似文献

Although mentoring others and career plateaus are both common experiences for seasoned employees, they are rarely examined together. In this study, we considered mentoring others as an antecedent of career plateaus and emotional exhaustion and turnover intentions as outcomes of career plateaus for mentors. We also examined the moderating role of mentors' proactive personality. Results of hierarchical regression analyses based on 188 mentoring dyads indicated that career-focused mentoring alleviated both hierarchical and job content plateauing perceptions. Mentors' proactive personality moderated the relationship between career-focused mentoring and hierarchical plateauing such that the negative relationship is stronger for low proactive personality mentors. Hierarchical plateaus were positively related to mentors' emotional exhaustion and turnover intentions whereas job content plateaus only positively related to turnover intentions. Proactive personality moderated the relationship between job content plateaus and mentors' work-related attitudes such that the positive relationships were stronger for more proactive mentors. The implications and future research suggestions are discussed.  相似文献

Drawing on a cultural perspective, we examined whether differences in self‐other decision making documented in the West can be replicated in an Eastern context. Study 1 revealed that Chinese participants showed self‐other decision‐making differences in loss aversion similar to those observed in Western participants; loss aversion differed depending on the type of decision recipient, and trait regulatory focus moderated the self‐other decision‐making difference. Study 2 found a mediating effect of situational prevention but not promotion focus on the relationship between decision makers’ roles and loss aversion. Furthermore, both studies revealed that participants did not show a preference for loss aversion, suggesting that the baseline of self‐other decision‐making differences has shifted in China compared to the West.  相似文献
