随着高等学校的快速发展,专业实验室的实验条件重复建设的现象越来越多,严重制约了各学科的实验教学、科研及学科建设与发展。如何改变学院内相近学科实验条件重复建设、实验室运行各自为政等难题,通过本科实验教学研究、研究生实验教学研究、科学研究服务和实验室建设与管理等几个模块建立基础上组建院级大实验室、进一步加强实验管理体制和实验队伍的建设的实践,改变了原来各自为政的局面,整合了学院现有资源,建立了学院急需的公共平台,使实验室(中心)在学科发展中发挥更大的主动性,同时也让实验室建设与管理水平得到提升,步入良性循环的发展轨道,产生了良好办学效益。 相似文献

针对传统图书自动推荐系统准确性不高的缺点,提出利用数据挖掘中的关联规则算法技术将读者借阅的图书、性别、年龄、职称、职业、受教育程度、爱好等多维关系生成关联规则,再将读者基本信息与这些规则进行比较,把匹配的关联规则推荐给读者,就能解决传统推荐系统的不足,提供更加灵活的个性化图书推荐服务。文章以湖南图书馆2011年读者借阅数据为例,利用Microsoft SQL Server 2008为工具进行了关联规则算法的数据挖掘分析。 相似文献

This study explored the concept of school connectedness and the factors that may influence its development with a sample of
Chinese adolescents. Six focus groups involving 52 high school students were conducted using a set of predetermined discussion
topics. Results indicated that the students fully understood the notion of school connectedness and could identify a number
of key influences affecting its development. These factors could be grouped under several domains including teacher care,
peer relations, broader school relationships, school disciplinary policies and practices, activities within the school’s guidance
and counseling program, and opportunities for talent development. The students were also able to suggest practical strategies
that schools might introduce to enhance and strengthen students’ acquisition of connectedness to school. The implications
from the findings are discussed with particular reference to implementing comprehensive school guidance and counseling program
in Hong Kong. 相似文献

With rapid development of the construction industry in China, lots of construction materials are being widely reused. Meanwhile, more and more materials for building remover or demolition enter into the environment as a result. However, China is facing big building garbage pollution, with simple disposal methods and low efficiency, which urgently needs to be improved. The paper takes Chongqing as an example to illustrate existing problems in this field and then puts forward corresponding countermeasures from the aspects of economy, technology, management and policy, aiming at enhancing the level of construction waste disposal in China. 相似文献

Objective
The efflux pump (EP) is one of the major mechanisms of antibiotic resistance in Klebsiella pneumoniae. However, there are few reports on the effect of the abuse of antibiotic use on the activity of EPs. To determine whether the use of low efficacy antibiotics has any effect on the activity of EPs and induces drug resistance in K. pneumoniae, we investigated the effect of ciprofloxacin on the activity of EPs in K. pneumoniae strains.Methods
Sixteen susceptible K. pneumoniae strains were isolated from patients and their minimum inhibitory concentrations (MICs) of ciprofloxacin were measured in the absence and presence of the pump inhibitor carbonyl cyanide m-chlorophenyl hydrazone (CCCP). The strains were then induced with a gradient of ciprofloxacin until the MICs of the strains showed no further increase, to obtain induced resistant strains. The EP activities of the strains before and after induction were compared using EP inhibition and ethidium bromide (EtBr) accumulation assays.Results
The MIC values of the strains were 16–256 times higher after induction than before induction. In the presence of CCCP, the MIC values of 50% of the induced strains were 2–4-fold lower than that in the absence of this inhibitor. The EtBr accumulation assay showed that the fluorescence of EtBr in the induced cells was lower than that in the cells before induction.Conclusions
EPs are widespread in susceptible and drug-resistant K. pneumoniae strains. Induction with ciprofloxacin may increase the activity of EPs in K. pneumoniae. The EtBr accumulation assay is more sensitive than the EP inhibition assay in evaluating the activity of EPs in K. pneumoniae. 相似文献96.

Despite the country's population base of 240 million, Indonesian television has not been widely explored in academic and professional venues. This paper examines the impact of competition on the popularity of foreign programs in the Indonesian market during the mid-1990s. Analyzing recently released ratings data from a television ratings service, this paper suggests that competition has given rise to the popularity of local programs, while foreign program popularity has declined steeply during the same three year period. The findings also suggest that cultural proximity is a factor of the popularity of programs. By 1997, Asian programs outnumbered Western programs on the top 100 highest rated program lists in Indonesia. We explore implications of study findings for filling this void in the literature. 相似文献

澳门特区自2007~2008学年开始实施15年免费教育,即9年义务教育、3年高中教育和3年学前教育免费.研究者运用网络调查及访谈法,对澳门特区免费幼儿教育政策进行研究,结果发现:(1)免费幼儿教育政策只适用于6家公办幼儿园和42家加入免费教育学校系统的私立幼儿园.(2)7家未加入免费教育学校系统的私立幼儿园需缴学费、补充服务费和选择性服务费,但可获政府发放的学费津贴和书簿费.家长很满意这一政策,并表示愿意继续送孩子上收费的私立幼儿园.(3)受访园(校)长、家长及教师对澳门的免费幼儿教育政策都很满意,教师特别满意政府推出的幼儿园教师津贴.(4)免费幼儿教育政策对私立园所的影响有所不同:有些私立园所为了生存而选择加入免费教育学校系统,有些私立园所则为了校政自主而选择不加入免费教育学校系统.客观上,高收费门槛令不同阶层家庭的幼儿自然分流. 相似文献
