美国主日学校图书馆是十九世纪基督教传教活动的一种辅助设施,以向儿童进行宗教和伦理教化为主要目的。作为公共图书馆兴起以前重要的图书馆形态,其定位、功能与作用值得系统深入的研究。主日学校图书馆的创设始于19世纪初期,1850年左右成为美国提供宗教文献和儿童读物的主要渠道,其广泛建立和发展一直持续到1880年,之后日渐式微。主日学校图书馆藏书重点由宗教文献向通俗童书过渡;分类编目处于草创阶段,较为粗略;读者服务规章严格,以闭架借阅为主;率先向儿童免费开放,是儿童图书馆事业的基石;培养儿童阅读习惯,促进了美国基础教育的发展;突破阶级、种族和性别壁垒,促进了公共图书馆民主、平等与包容等服务理念的形成;遍布美国各地,奠定了农村图书馆事业发展的基础。表1。参考文献38。  相似文献

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献

If the shoe doesn’t fit, it is a mistake to change the foot, but in essence this is what occurred in 20th-century China, in the context of rural construction. Motivated by self-preservation, nationalist forces in China resisted the hasty, indiscriminate and harmful importation (indeed, imposition) of western influences, but these external influences ultimately predominated over traditional domestic practices. Radical ideologies evolved, destroying traditional construction methods while promoting ill-conceived, but ostensibly “modern” counterparts, or chaotic syntheses of old and new. Rural economies were devastated, to the despair of peasants. The internal response to external stimulus had become far more damaging, the cure its own fatal disease. Amid ongoing efforts at reconstruction, local committees were formed that varied in efficiency, and successive waves of rural construction featured a wide array of approaches, far more than merely “top down” or “bottom up (grassroots).” And yet, while conditions have improved, the symptoms of radical response persist. The proper cure should be context-dependent reform.  相似文献

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.  相似文献

Based on a nation-wide survey of higher education graduates, this paper analyzes the impact of family background, using paternal occupation and education as indicators, on their scores in the National College Entrance Examination, the level and type of higher education institutions they attend, their employment after graduation, and the income they receive from their first job. It has been found that there are wide disparities among students with different family backgrounds in both access to higher education and their potential employment in China nowadays. This paper also studies how those influences happen. __________ Translated from Peking University Education Review, 2005 July (3)  相似文献

高校人才集聚绩效评价方法探析:集聚指数的编制与应用   总被引:1,自引:0,他引:1  
优秀人才的集聚是高校核心竞争力提升的首要前提,而如何考量高校人才集聚的绩效成为亟待解决的难题。本研究运用统计指数相关方法编制了高校人才集聚指数作为绩效评价的一种方法,并进一步选择位于东北、西北、中部、东部和东南的5所“985”高校,对其2000年以来人才集聚指数进行测算,通过分析测算结果发现五所高校的人才流动均呈逐步优化的发展态势,且发展态势相对稳健,但高校间人才集聚绩效存在一定差异,而差异幅度在一段时间内表现得相对稳定。  相似文献
