Self-esteem: A cross-cultural comparison of British-Chinese,White British and Hong Kong Chinese children

Total raw self-esteem scores of 1303 children, including Chinese children in Britain and Hong Kong and White British, were assessed by using the Self-esteem Inventory developed by Coopersmith (1967). Across all samples, the results show little differences between children of different ages, whereas statistically significant differences occur in the independent variables of ethnic groups, gender and educational aspiration. Despite the social disadvantages that the UK Chinese may face, they have significantly higher self-esteem than their Hong Kong Chinese counterparts, but have little differences from their White peers. This indicates that they are likely to have positive feelings and academic confidence in being themselves and as part of the host society. In contrast, Hong Kong children tend to have low levels of self-esteem, which may be caused by the more self-effacing and modest values in Chinese culture, a traditional authoritarian style of education or highly competitive pressures created by schools, families and society.     

国有企业全面退出竞争性行业质疑

让国有企业全面退出竞争性行业是一种错误的退却 ,不符合社会主义经济制度、“抓大放小”战略、民族工业发展等方面的要求 ,这将使国有企业的振兴和国有经济实力的增强丧失有效的经济阵地 ,同时这也由于竞争性行业难以准确界定和缺乏有效途径而行不通。     

IEEE 802.11无线网状网中的一种干扰感知的多径路由协议

基于IEEE 802.11 MAC层协议模型,提出一种新颖的能够描述多条路径之间干扰程度的多径路由判据IAMM,并以此为基础,提出一种新的干扰感知的多径路由IAMR协议.IAMR协议通过2次选路,在保证单条路径性能的同时兼顾考虑路径之间的干扰因素.仿真实验表明,IAMR协议在端到端延迟、数据包到达率和吞吐量等方面均有较明显的性能提升.     

碳纳米点的制备及其非线性光限幅性能研究

以肝素钠为碳源,通过水热合成法制备碳纳米点（CNDs）,对所制得的CNDs形貌、组成及线性光学性能进行系统研究。结果表明,CNDs粒径均一,且表面富含羧基和羟基等官能团;在270 nm处有明显的紫外吸收峰。CNDs具有与激发波长相关的荧光特性,发射峰随激发波长增大的而红移。采用开孔Z-扫描法探索CNDs的非线性光学效应,结果表明,CNDs具有与能量相关的从饱和吸收向反饱和吸收转变的特性,其非线性吸收系数β和饱和能量IS分别为1.4×10^-11m/W和8×10¹⁰W/m²。     

复合绿色缓蚀剂在自来水中对A3钢缓蚀性能的研究

采用热缩聚法以L-天冬氨酸为原料合成了聚天冬氨酸（PASP）,并采用失重法与极化曲线法研究了在中性水体系中PASP对A3钢的缓蚀性能。实验结果表明,PASP对A3钢有较好的缓蚀作用,在该体系中是以抑制阳极为主的吸附型缓蚀剂,与抗坏血酸复配有协同作用,缓蚀效果最高达90%以上。     

Goal orientations and achievement among Chinese gifted students in Hong Kong

This study examined four goal orientations and their relationships to achievement among 1041 Chinese gifted students in Hong Kong. These students endorsed learning and social goals over performance‐approach and performance‐avoidance goals. The endorsement of learning goals emerged consistently as the significant predictor predicting achievement in academic, non‐academic, and social/leadership areas. Implications of the findings for coordinating different goal orientations for enhancing achievement in different areas are discussed.
