哈密尔顿系统具有很多本质的性质，如保面积、保能量和动量等，而最重要的是自治哈密尔顿系统相流的辛性质，这为保相面积和相体积提供了保证，因此我们希望差分格式在被用来求哈密尔顿系统的数值解时能保持这种辛性质。在文献［１─３］中，冯康等人发展了哈密尔顿系统辛差分格式的一整套理论。本文主要考虑辛ＲＫＮ方法及显式辛格式的阶条件，并给出一些高阶辛ＲＫＮ格式，还提出一种利用低阶格式构造高阶格式的方法。此方法对辛格式和非辛格式均适用。限于篇幅，本文略去大部分定理的证明并尽可能简化说明。 相似文献

The literature on quality-management standards has generally focused on the drivers, motivations, and performance effects of adopting such standards. Yet the last decade has witnessed a substantial degree of decertification behavior, as organizations have increasingly decided to voluntarily withdraw from quality-management standards by not recertifying. While the drivers of the decision to initially adopt quality-management standards have been extensively studied, the drivers of the decision to decertify have received scant scholarly attention. We argue that innovative organizations are generally prone to retaining quality-management certification and thus exhibit a tendency to not abandon certification; however, radically-innovative organizations are more prone than incrementally-innovative organizations to discontinue quality-management standards and thereby exhibit a tendency to withdraw from quality certification. We compile World Bank data surveying facilities based in 50 countries and 103 industrial sectors across the 2003 to 2017 period. Taking advantage of the data's panel properties yields a dataset composed of up to 1755 facility-level observations of recertification decisions for empirical analysis. Our empirical testing employs a probit estimation technique that accounts for the appropriate fixed effects and generates results that support our theoretical priors regarding decertification behavior. 相似文献

Developing customer product loyalty through mobile advertising: Affective and cognitive perspectives
Mobile advertising is an increasingly popular marketing channel since it can present advertising in a personalized manner. This study examines the development of customer product loyalty through mobile advertising by considering the drivers from affective and cognitive perspectives. An Expectation Confirmation Model (ECM), as defined for repurchase intention, is proposed as a theoretical basis for the relationship structure of related research variables. An Elaboration Likelihood Model (ELM) identifies affective and cognitive concerns for defining the drivers of consumer behavior. Involvement and interactivity confirmation arise as affective and cognitive concerns in this context. This research model also indicates a particular mediating role of perceived usefulness and customer satisfaction from the two drivers for developing customer product loyalty. Empirical analysis shows that both affective and cognitive perspectives, i.e., involvement and interactivity, are important drivers to motivate customer product loyalty. The findings can help practitioners design more effective approaches for mobile advertising. 相似文献

This paper reviews recent evidence on technology transfer to the rapidly growing Western Pacific region, where most developing countries have adopted relatively liberal policies towards the importation of technology and equity capital. In recent years Japan has emerged as a major supplier of technology to the region. Moreover, there have been important changes in the international technology market, which has become larger and more competitive. Nevertheless, many aspects of technology imports have been criticised, including the conditions attached to its sale, and its appropriateness for low income countries. The arguments for limited regulation of technology flows are assessed and the economic and administrative difficulties pointed out. From the host country viewpoint, the policies influencing diffusion of technology within the country seem to be at least as important as the policies directly bearing on technology transfer from overseas. 相似文献

There is probably no more dramatic an example of a developing country acquiring an industrial capability demanding the highest levels of technological and managerial skills, than that of the Indian nuclear industry. With the detonation of a nuclear device by India, much concern has been expressed that this is a case of nuclear proliferation resulting from an aid programme of a western state (Canada).This study demonstrates that rather than an aid programme, Canadian/Indian nuclear cooperation has been mutually beneficial to both countries' industries. In fact, India was a full risk-sharing partner in the development of the CANDU technology. It is also shown that there were no agreements with Canada broken by the Indian Government and that the detonation of the device was not a consequence of the links between the two programmes. Differences between the structures of the Canadian and Indian nuclear industries and the implications of these differences to broader national policies are discussed.The paper offers a basic criteria for the determination of the ‘appropriateness’ of a technology which, if applied to commercial nuclear power generating reactors, would result in a very gradual proliferation of this technology. In discussing the process of technology transfer, the paper identifies an optimal relative level of development between the industries of the two nations concerned. This relationship suggests that the most likely pattern of transfer in the future will be between LDCs that wish a new technological capability and other LDCs that have already acquired a certain level of competence. 相似文献

This paper investigates the effect of within-country and across-country inequalities on firms’ FDI performance, and finds drivers of success in an advanced host economy (the USA) differ for firms from developed compared to developing countries. Returns to FDI for firms from developed countries are significantly correlated with home countries’ level of economic development. In contrast, successful developing-country firms are from countries with lower within-country inequality, and reflect the industrial structure associated with developing countries: They are concentrated in scale-intensive industries and benefit especially from capital investment. The findings suggest that FDI reflects rather than disrupts unevenness in knowledge bases globally. 相似文献

依据地理位置和医疗水平与设施把我国医院分为两个战略群组:中心医院和基层医院。基于这一战略群组划分,分析了我国医院间合作的市场动因和政府动因。结论认为,在医疗体系改革的影响下,中心医院合作的市场动因是通过合作扩大他们的影响,获取更多"病源",发挥规模经济优势;基层医院合作的市场动因是通过合作获取知识来提高自身的能力。另外政府为了改善医疗服务,也在促进基层医院与中心医院之间的合作,形成了我国医院间合作的政府动因。 相似文献
