Influence of plastic strain localisation on the mechanical properties of metal matrix composites

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible.     

Cultural influences in acquiescent response: A study of trainer evaluation biases

The current study is developed to identify factors that affect trainees’ acquiescent tendency in organizational trainer evaluations. We posit that conflict‐handling style affects ones tendency to acquiesce in trainer evaluations, and this relationship is regulated by cultural influence. Surveys were sent to employees with training experience in Taiwan and North America, 395 valid responses were collected. Results showed that the two individual conflict‐handling styles: non‐confrontation style and dominating style, are positively related to acquiescent tendency; and their relationship is found moderated by the influence of Confucian work dynamism, thus confirming the influence of cultural norms. Our findings contribute to HRD practitioners by highlighting the different conflict‐handling style and culture influence will result in different level of acquiescent propensity, trainer evaluations results should be interpreted more carefully and cautiously.     

Psychometric Properties of the Acceptance and Action Questionnaire – II for Taiwanese College Students and Elite Athletes

The aim of this study was to validate the Taiwanese version of the Acceptance and Action Questionnaire-II (AAQ-II) using a population that consisted of college students and athletes. The authors conducted three independent studies to examine the psychometric properties of the AAQ-II. Study 1 examined the validity of the AAQ-II in a sample of undergraduate students. Study 2 examined the group invariance of the AAQ-II between undergraduate students and athletes. Study 3 examined nomological validity by testing the mediating role of experiential avoidance in the relationship between perceived autonomy support and well?/ill-being indicators. Overall, the results of the confirmatory factor analyses conducted in Study 1 demonstrated the existence of a unidimensional AAQ-II. AAQ-II was positively correlated with depression. The internal consistency of the scale was 0.81. In Study 2, factorial invariance of the AAQ-II was demonstrated across undergraduate students and adolescent athletes. Study 3 showed that perceived autonomy support was related to both depression and negative emotion through experiential avoidance. However, experiential avoidance did not mediate the relationship between perceived autonomy support and positive emotion and life satisfaction. In summary, this study provided preliminary evidence to support the validity and reliability of the AAQ-II and opened a new avenue for cross-cultural researchers.     

胡煦与朱熹对"太极""道器"理解之分歧

胡煦是清初一位重要的易学家、理学家,他的思想有很多独到之处,持论酌于汉学、宋学之间,与朱子颇有异同.朱熹认为太极即是理,把理看作是万物的本体.胡煦则认为太极是本体,理只是其用,太极不仅立于形器之先,也在理之先.朱熹以理为形上之道,而以阴阳为形下之器.胡煦认为"一阴一阳之谓道",则阴阳应为形上之道,道与阴阳实为一也.胡煦与朱熹对"太极""道器"等概念理解的差异反映了清初学术界思想的转向.     

自我反思对初中生解题策略的影响

本研究选取初一至初三年级学生为被试,采用实验法,用数学连加数问题为实验材料,就自我反思对解题策略的影响进行了研究。比较了有反思实验组学生(24人)和没有反思控制组学生(29人)解题策略的差异,结果发现:(1)有反思的学生比没有反思的学生更多使用高效策略;(2)从测试过程策略类型的变化看,反思促进初中生逐渐获得高效策略,放弃低效策略。     

认知负荷对小学生工作记忆资源分配策略的影响

以不同认知负荷的连环数认知运算为实验材料,以小学三到六年级175名学生为被试,考察了认知负荷对小学生工作记忆资源分配策略的影响。结果表明:认知负荷的难度明显地影响到了小学生工作记忆资源分配策略。在策略的选择方面,认知负荷对于小学生认知操作成绩的影响力在低年龄段时没有达到显著性差异,而小学六年级则差异显著;在策略的正确率方面,认知负荷难度的影响力随年级的升高而相对减少;在策略的解题速度方面,认知负荷的难度也明显地影响到了小学生工作记忆资源分配策略的解题速度。     

中小学教师健康坚韧性及影响因素的研究

坚韧性是一丛能够保护个体免于应激伤害的人格特质,包括承诺、控制和挑战三部分内容。以中小学教师为被试,采用问卷调查的方法考察教师的健康坚韧性状况和影响因素。研究发现,教师的健康坚韧性整体上较为理想,教龄、性别、婚姻状况、学校层次和学历水平是影响教师健康坚韧性的重要因素。     

辽宁省农村不同经济水平地区居民医疗保健需要、需求与利用

对2001年对辽宁省农村医疗保健需要、需求和利用进行调查.样本选择主要根据不同地区经济水平,抽取9个县、27个乡、54个村,共调查了1084户、3 812人.分析了不同经济水平地区农村居民的患病率、医疗服务利用频率、就医流向、医疗费用支出水平及其在家庭支出中的比例、患病未利用原因及比例的差异和特征.并分析了医疗需要和利用的变化状况,调查对象对农村医疗保障形式的意愿.研究结果揭示低经济水平地区居民高需要、低需求、未就医率高、医疗费用负担重的状况.     

医疗保健政策与医患关系

医疗保健政策深刻地影响着医患关系,并左右着医患关系的发展与变化.在实行"以公平为主,兼顾效益"的福利性的医疗保健政策时期,我国的医患关系是和谐的.但自从医疗保健政策向"经济导向型"方向转变之后,国家大幅度减少了对卫生事业的投入,医院必须从病人身上取得卫生发展必要的资金,医药费用上涨是必然的,也失去了公平和公正,并最终导致医患关系的恶化.调整医患关系不能仅从医、患两方面着手,建立符合医学伦理的卫生政策,才是问题的关键.     

《黄帝内经》阴阳二十五人分型的数学建模

目的:应用数学建模的方法探索<黄帝内经>阴阳二十五人分型的相应关系.方法:根据<黄帝内经>理论对阴阳(X1)、五行(X2)、五音(X3)和阴阳二十五人健康状态(Y)进行量化,通过SAS循环程序进行数据模拟,建立多元回归模型.结果:多元线性回归方程为Y=7452.24162+625 X1+25X2+0.09832X3.结论:方程揭示了阴阳、五行和五音与阴阳二十五人健康状态的理论关系,为进一步求证阴阳、五行、五音与健康的关系提供了一个数学模型.
