新中国农地制度:绩效与变迁

新中国成立以来,中国农地制度主要有三种类型:土改时期的私有私营制、人民公社的公有公营制和改革开放以来的公有私营制。三种农地制度的绩效差异极大,各自的缺陷导致其处于不断的变迁之中。但无论任何变迁,中国农地制度必须同时兼顾效率和公平,农村土地必须同时承担资产与社会保障两种功能。这既是当前农民认同土地集体所有制的主要原因,也是今后农地制度改革必须考虑的重要因素。     

“莱昂假说”与克隆性分析技术的思想启迪

克隆性分析技术已经很大程度上影响和改变着人们对肿瘤的思维。“莱昂假说”的创立、印证以及克隆性分析技术的发展、应用,已经使我们重新认识了许多肿瘤和肿瘤前期病变的性质。其间的研究工作启示我们,科学需要源于事实基础的大胆猜测,更需要有求异性思维,敢于突破、善于联想根源于深厚的知识沉淀。

从词汇的角度看《撰集百缘经》的译者及成书年代

目前学术界对《撰集百缘经》的作者与成书年代看法不一,本文主要从文献与词汇的角度对《撰集百缘经》作一番考定。     

Cultural differences in attitude toward and effects of self‐doubt

It has been argued that the high achievement of Confucian Asian students is at the cost of their psychological well‐being, since high self‐doubt consistently accompanies their high achievement. However, other researchers cautioned that the attitude toward self‐doubt could be different in Asian versus Western cultures. This study examined the debate with a survey of both American and Chinese college students that measured level of self‐doubt, attitude toward self‐doubt, beliefs about ability, and psychological well‐being outcomes. As hypothesized, Chinese students showed a more positive attitude toward self‐doubt than American students, despite having higher level of self‐doubt. Furthermore, self‐doubt engendered less negative consequences on Chinese students' psychological well‐being, relative to American students. Implications for theories and research on cultural differences in the effects of self‐constructs are discussed.     

A standardised database of Chinese emotional film clips

Film clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validity. Eventually, 22 film excerpts that successfully evoked three positive emotions (joy, amusement, and tenderness), four negative emotions (moral disgust, anger, fear, and sadness), and neutrality formed the standardised database of Chinese emotional film clips.     

Livin在小细胞肺癌中的表达及与Caspase-3相关性研究

为了探讨Livin蛋白在小细胞肺癌（SCLC）组织中的表达及与Caspase-3的关系,我们使用免疫组化法检测Livin和Caspase-3在30例SCLC及癌旁肺组织中的表达。结果显示,Livin在SCLC中表达明显高于正常组织（P〈0．01）,与TNM分期、淋巴结转移和肿瘤大小无关。Caspase-3在SCLC组织中表达明显下降（P〈0．01）,与Livin表达呈负相关。因此,Livin与Caspase-3的异常表达可能在SCLC癌变中起协调作用,并有望成为诊断和基因治疗的新靶点。     

现代健康理念刍议

医学人文教育仍然处于薄弱的状态,与其重要性极不对称,造成此种局面的症结之一在于现有的学制学时紧张,难以有序地开展课堂教育教学。面对医学人文教育所处的困境,采取医学人文辅修专业的形式不失为可以探索的途径,化解学时紧张的矛盾,推动医学人文教育尽快开展。     

广东省城乡初中生元认知水平比较研究

研究采用自编问卷和访谈法对城乡初中生进行元认知水平的对比研究,结果表明：1）城乡初中生元认知水平总体差异显著,农村初中生的元认知水平总体低于城市初中生的元认知水平。2）城乡初中生在认知前元认知体验和认知中元认知知识维度上差异显著。认知前元认知知识、认知中元认知体验、认知后元认知知识、认知后元认知体验之间无显著性差异。建议加强教师和学生元认知训练,提高学生元认知水平。
