建立信息产业综合指标体系的思考

在对信息产业加以界定的基础上,建立起了信息产业综合指标体系,用量化的方法对信息产业的发展水平进行描述。     

Homework involvement and functions: perceptions of Hong Kong Chinese primary school students and parents

This study examines the perceptions of Chinese students and parents in Hong Kong on homework involvement, assignment type and homework functions. The relationships of homework perceptions to student and parent attributes are also assessed. The sample includes 1393 pairs of students and their parents from 36 primary schools in Hong Kong. Findings of this study show similarities in preference for assignment type across students and parents. Between‐group discrepancies are observed in preference for homework involvement and endorsement of homework functions. Moreover, homework perceptions are found to relate to students’ and parents’ efficacy attributes and involvement behaviour. Findings of this study are discussed in light of the Chinese sociocultural context in Hong Kong. Suggestions are made on the design and use of homework in primary schools by incorporating the views of different stakeholders.     

Teacher-education students’ views about knowledge building theory and practice

This study investigated the effects of engaging students to collectively learn and work with knowledge in a computer-supported collaborative learning environment called Knowledge Forum on their views about knowledge building theory and practice. Participants were 24 teacher-education students who took a required course titled “Integrating Theory and Practice in Teaching.” Data mainly came from (1) student discourse recorded in a Knowledge Forum database, (2) a survey that examined students’ views about knowledge building, and (3) interviews with regard to students’ perceived barriers to implementing knowledge building theory in teaching. Findings suggest that with sustained discourse to construct their collective understanding of the relationships between theory and practice in teaching for a semester, the participants were able to attain more informed and practical views about knowledge building theory. In addition, students’ perceived barriers to implementing knowledge building in teaching were identified and strategies to help overcome these barriers discussed.     

抑癌基因PTEN载体构建及在LOVO细胞中的表达

目的:构建抑癌基因PTEN的表达载体并在LOVO细胞中表达。方法:从人外周血中提取总RNA,通过RT-PCR扩增出PTEN基因片段,将PTEN基因连入pLenti6/V5载体。测序鉴定后,经脂质体转染入LOVO细胞,对细胞株进行RT-PCR和Western blot检测。结果:DNA测序证实pLenti6/V5-PTEN表达载体为阳性克隆;该表达载体转染LOVO细胞后上调了PTEN mRNA和蛋白的表达。结论:成功构建了pLen-ti6/V5-PTEN表达载体,为进一步研究PTEN在LOVO细胞中的功能奠定了基础。

北魏《韩玫墓志》四题

北魏正光五年(524年)《韩玫墓志》所载志主家世、家族郡望及其生命后期的仕宦抉择颇有价值。《韩玫墓志》所载高祖韩苟、曾祖韩元兴,即《魏书·韩茂传》之韩耆、韩茂。韩茂家族并非如姚薇元先生所说出自匈奴族,而应是先被赫连夏政权吸纳,后又进入北魏政权的安定地方汉人豪强。孝文帝定姓族后,韩玫家族进入新门阀序列,志主韩玫即凭依门第入仕。门阀化后的韩玫家族舍弃旧贯,攀附南阳郡望,入唐以后其后裔又改以昌黎为郡望,由此可见北朝隋唐间郡望兴衰之于身份认同的意义。从韩玫生命后期的仕宦抉择,可以窥见高阳王元雍与正光政局关系之一端。     

加入WTO对重庆劳动就业的影响分析

加入世界贸易组织必将对我国三次产业结构产生巨大影响,由此带来各行业劳动就业的变动,具体表现为第一产业要释放和转移大量剩余劳动力;第二产业中有国际竞争力行业会吸纳一些劳动力,而一些夕阳产业则要大量裁员;第三产业总体上说发展潜力巨大,被视为吸纳劳动力的重要途径。     

仰韶彩陶文化中的“日与乌”纹饰

自古以来,中国古代先民就怀着对自然的崇拜和敬畏之情,将与他们生活息息相关的自然生灵作为精神寄托和崇拜对象,并作为纹饰记载在他们创造的器物上。太阳崇拜与乌灵崇拜,是人类社会最早的两大崇拜,而且太阳崇拜几乎跟乌灵崇拜融为一体。陕西华县泉护村仰韶文化遗址出土的鸟纹彩陶中,有一个形象为日与乌组合的纹饰颇为引人注目,乌是鸟的一种,这也与中国的一部分神话故事中的情节相吻合。这一纹样是太阳崇拜的一种表现。对于类似彩陶纹样的研究,能体现彼时彼地人类某种观念、精神和情感。
