An analysis of the changing doctor-patient relationship in China

As China is undergoing marketization and privatization, the doctor-patient relationship (DPR) is changing, posing numerous social problems such as a trust crisis. In this article, the authors look at the characteristics of the DPR, and then present an historical account of the changing features of the Chinese DPR. In the final section, they explain how Chinese traditional culture is important for rebuilding the DPR in reform-era China and make suggestions for its health care reform.     

Electronegativity difference as a factor for evaluating the thermal stability of Al-rich metallic glasses

This article proposes a factor, the critical electronegativity difference Δx _cri, to correlate alloy composition with thermal stability and glass-forming ability of Al–Ni–RE (RE: Rare Earth element) ternary metallic glasses. The Al-rich metallic glasses with Δx > Δx _cri exhibit glassy behavior, whereas alloys with Δx < Δx _cri are nanocrystalline. Nanoglassy alloys occur when Δx ≈ Δx _cri. The best glass formers are located near Δx _cri. Furthermore, an equation has been deduced to calculate Δx _cri with varying RE covalent atomic radius.     

Efficient atomic packing clusters and glass formation in ternary Al-based metallic glasses

In this article, we propose an efficient atomic packing cluster-based composition protocol to help design Al-based metallic glasses. Its validity is verified by some typical experimental data from the literatures. Furthermore, with this understanding, the Al–Ni–Y alloy system is re-evaluated. As a result, the best glass former Al₈₆Ni₉Y₅ in this system, with the critical thickness of about 500 µm, is successfully fabricated by wedge casting.     

双任务干扰的注意资源限制机制:来自汉字笔画数效应的证据

该研究的两个实验采用心理不应期范式,探讨了重叠任务情境下双任务的相互干扰机制。实验中被试相继完成高低音的辨别任务(T1)和汉字外在特征(颜色或笔画数)的任务判断(T2),T1和T2间采用变化的SOA。结果发现:(1)T1的反应选择导致T2的加工成绩大幅下降,PRP效应非常显著。(2)当T1占据中枢瓶颈时,T2和T1在中枢瓶颈中并行得到加工并导致T1的加工效率显著下降。(3)由于注意资源的有限性,具有自动激活特征的汉字同样受瓶颈机制的限制。只要存在对注意资源的二次分配就会存在瓶颈的调节机制。     

Relativism and Faultless Disagreement

The argument from faultless disagreement employed by the relativist purports to show that contextualism falls short of explaining cases of faultless disagreement. The demonstration is intended to give credence to the relativist semantics of epistemic modality expressions. In this paper we present some cases showing that even though cases of faultless disagreement do reveal some intrinsic features of epistemic modality claims, they do not support the relativist semantics. The sophistication of faultless disagreement goes beyond what the relativist semantics can cope with. We also advance an epistemologically oriented proposal to account for faultless disagreement.

目的：探讨大学生家庭因素中父母情感温暖教养方式、文化性家庭环境与责任心对职业决策自我效能的中介效应与中介调节效应。方法：采用责任心量表、职业决策自我效能量表、父母教养方式评价量表和家庭环境量表,对大学四个年级1207名学生进行测量,运用SPSS12.0、AMOS17.0对数据进行统计分析。结果：（1）父母情感温暖通过责任心对大学生职业决策自我效能具有稳定而持久的间接作用。（2）文化性作为父母情感温暖的调节变量,其与父母情感温暖的交互作用对责任心具有明显的预测作用,并通过责任心中介变量,对大学生职业决策自我效能产生稳定而持久的间接作用。     

Microstructural characterization of the M23C6 carbide in a long-term aged Ni-based superalloy

The microstructural features of M₂₃C₆ carbide in a long-term aged heat- and corrosion-resistant Ni-based superalloy have been investigated in detail using various kinds of transmission electron microscope (TEM) techniques. It is found that TEM contrast, which is related to structural and chemical inhomogeneities inside the grains, always exists in the interior of grains in the alloy. The structure of these inhomogeneous regions has been determined to be the same as that of the γ′ and t-M₂₃C₆ phases, where t-M₂₃C₆ indicates a transitional and metastable phase. Although possessing the same structure as the M₂₃C₆ phase, the chemical composition of the t-M₂₃C₆ is different from that of the M₂₃C₆ phase. Compared with M₂₃C₆, t-M₂₃C₆ is richer in Ni, Co, Al and Ti but poorer in W, Mo and Cr. This phenomenon of structural and chemical inhomogeneity demonstrates that pristine M₂₃C₆ carbide (p-M₂₃C₆) precipitated in standard heat-treated samples is unstable. Therefore, upon long-term ageing treatment, Ni, Co, Al and Ti may locally enrich inside the p-M₂₃C₆ phase, finally forming the γ′ phase, which can be described by the decomposition reaction p-M₂₃C₆ → M₂₃C₆ + γ′.     

Effects of parental expectations and cultural-values orientation on career decision-making difficulties of Chinese University students

This study examined the effects of cultural-values conflict and parental expectations on the career decision-making difficulties of university students in three cities in China (Beijing, Wuhan, and Hong Kong, N = 1342). The Multidimensional Scales of Individual Traditionality and Modernity (Yang, Yu, & Ye, 1989) were used as a measure of cultural-values conflict and cultural orientation. The Living-Up-to Parental Expectation Inventory (Wang & Heppner, 2002) was used to measure parental expectations. The Career Decision-Making Difficulties Questionnaire (Gati & Saka, 2001) was used as a dependent measure. It was found that levels of cultural-value conflict were associated with higher levels of career decision-making difficulties for students in the Chinese Mainland cities but not for students in Hong Kong. Perceived parental expectations and perceived self-performance in the expected areas were found to be predictive of career decision-making difficulties. Cultural-value orientation, especially endorsement of Chinese traditional values, was found to moderate the relationship between parental expectation and career decision-making difficulties. Theoretical, research and practical implications of findings were discussed.     

夫妻依恋风格、婚姻归因与婚姻质量的关系

本研究采用主—客体互倚模型(actor-partner interdependence model,APIM)的方法深入探讨夫妻的依恋风格、婚姻归因与自身及配偶感知到的婚姻质量之间的关系。以方便取样的方式在北京地区选取155对夫妻,采用Brennan等(1998)编制的亲密关系经历量表(ECR),Stander编制的婚姻归因量表(MAQ)和Spanier编制的婚姻质量问卷(DAS),要求夫妻双方分别报告其依恋风格、婚姻归因方式和感知到的婚姻质量。通过配对t检验、相关分析和结构方程模型分析发现:(1)夫妻对婚姻质量的总体知觉较为一致,但丈夫的婚姻满意度显著高于妻子;(2)夫妻双方在回避依恋和焦虑依恋两个分量表上不存在显著差异,但在婚姻归因上,妻子比丈夫表现出了更多的消极归因;(3)妻子的消极依恋显著地负向预测自身感知到的婚姻质量,而丈夫的消极依恋对自身感知到的婚姻质量没有显著影响;(4)在控制了丈夫、妻子的依恋风格、归因方式对其自身婚姻质量的主体效应之后,丈夫的依恋风格不能显著预测妻子感受到的婚姻质量,但其归因方式可以显著地预测妻子感受到的婚姻质量;然而妻子的归因方式并不能显著预测丈夫的婚姻质量。     

3～5岁幼儿元认知监控发展特点的研究

该研究以北京市某幼儿园5个班98名幼儿为被试,利用拼图任务对其元认知监控能力的发展特点进行了探讨,结果发现:3～5岁幼儿在活动操作过程中,随着年龄的增长,注视目标的次数增多,完成任务的总时间在缩短,正确率在提高,但是悔步次数和停顿次数随着年龄变化的差异不显著;同时,注视目标的次数和停顿次数随着任务难度的变化而变化,表现出了一定的元认知监控能力。
