查询词典 networks

This study intends to propose a combination of systems thinking and policy networks perspective in developing network accountability of contracting out social services. Both systems thinking and policy networks have been applied to public policy analysis for many years. As a perspective that emphasizes the whole rather than fragmented parts, systems thinking has been considered effective in uncovering structural flaws that limit system performance and explaining why a well-intended policy intervention fails to produce expected results.

系统思考和政策网络在公共政策研究领域中已盛行多年，由于此两种途径有许多相似的特质，而同时才者的相异之处又可在政策研究中达到互补的功能，因此，本研究试图将系统思考与政策网络相连结，来探讨社会福利委外系统中网络课责的建构。

The empirical results indicate that the method based on neural networks excels the BS model in interpretive capability, error degrees and hedging efficiency. It means that in the Taiwanese warrant market, neural networks with self-evolving genetic algorithms can provide a more accurate and stabler model on pricing and hedging than the BS model.

研究结果显示，类神经网路模型针对台湾已到期之十五档认购权证，不论在评价上之解释能力与误差程度，或在避险效果上均优於BS模型，即表示在台湾认购权证市场中，基因演算法自动演化之类神经网路能提供一个比BS模型更接近市场价格，以及更能替发行者规避暴露风险的模型。
