隆昌石牌坊群成因初探

四川隆昌被誉为“中国石牌坊之乡”,现存17座明清时期的石牌坊。古驿道、移民大族、地方官僚、隆昌青石、民房与牌坊的关系这几个恰到好处的因素共同构成了隆昌蔚为壮观的石牌坊群。     

基于蚁群算法的最小电路测试集生成算法

为了提高电路故障的测试速度和精度．在现有的传统故障测试集生成算法的基础上,引入蚁群生物的路径规划策略,设计一种基于蚁群算法的电路故障最小测试集生成算法。详细阐述蚁群算法的设计思想,给出数字电路测试问题向蚁群规划问题的转换过程,包括基于蚁群算法的最小测试集生成流程。并对设计的电路故障最小测试集生成算法进行了理论上的性能分析和实际的测试验证,测试结果表明该算法具有较高的综合效率。     

Rationalising public support for private early childhood education and care: the case of Finland

ABSTRACT

In Finland, early childhood education and care (ECEC) is traditionally publicly provided. However, private ECEC provision has increased during the past decade, largely as a result of financial support from the public sector. Drawing on qualitative interviews with municipal decision-makers, this article identifies three frames within which publicly subsidised private ECEC provision and marketisation are rationalised: the pragmatic frame, the government frame and the choice frame. The results show that even though market logics and tendencies seem to have gained a strong foothold in local policies, there is a keen interest in universalism and maintaining public control over local ECEC provision.     

如何提高高师声乐集体课的教学效果

高校扩招后，高师声乐课的教学由原来的一对一的授课方式转变为一对多的小组授课方式，在教学时间不变的情况下，如何提高教学效率已成为急待解决的问题。本文通过对声乐小组课特点的分析，从实践基础上对如何提高声乐小组课的教学效率提出了行之有效的方法。

Art and Design Education in the Ecology of Care

In the light of challenges arising from contemporary issues such as inclusivity, sustainability and justice, the connections between art, design and caring appears to be pertinent. What role can artists and designers play in the ecology of care? How can we lead art and design students to connect and lend their creative skills to care needs? Drawing on the ethics of care and a relational view on health this article highlights the various teaching approaches and initiatives introduced at Nanyang Technological University, Singapore, to support and guide students to realise various art and design for health and wellbeing projects that provide opportunities for students to part take in ecology of care using their creative skills. Although creative explorations at the intersection of art, design and caring is still at an early stage, outcomes from this ongoing effort have been encouraging in response to the shifting social needs to create a more inclusive and flourishing society in Singapore.     

S~1等变的凝聚算子的拓扑度及其应用

本文首先证明了:S~1等变的凝聚算子的拓扑度可以用Boruwer度来计算;由此导出了具有非线性稳定或不稳定差分算子的中立型方程的周期边值问题可解性定理。还证明了,半线性泛函微分系统的共振点在几乎任意的时滞扰动下将消失。     

试论企业集团产生和发展的动因

自20世纪80年代以来，我国学者对企业集团的理论建设进行了一些有益探讨，但是他们大都没有跳出科技的交易成本分析框架。交易成本分析实际上只是一种静态分析方法，仅能在既定条件下分析各商业交易主体的哪些商业交易应当选用企业集团内部市场来组织、哪些商业交易又应当选用企业外部市场来组织或企业内部市场来组织，但无法揭示在动态条件转产发展的深层原因，因而使用这一分析框架所得出的结论都不可避免地带有一定的局限性。如果将垄断和竞争因素以及专业化因素引入交易成本分析框架，就能较好地理解企业集团的产生和发展。
