军事医学语言是军事语言学的一个分支学科。古今中外的军事医学实践表明,军事医学语言在医学工作中发挥着重要作用,有时对医疗效果起着决定性作用。我国古代十分重视运用军事医学语言保障部队提高医疗效果的作用。但是,军事医学语言学科还不成体系,严重影响着军事医学工作科学效能的发挥。加快军事医学语言学科体系建设,已经成为当前巩固和提高部队战斗力中一个不可忽视的课题。  相似文献

军事指挥类期刊主要依靠各级军事指挥员,服务于部队全面建设。在军事学术研究队伍不断发展壮大的今天,军事指挥类期刊为部队“能打仗、打胜仗”军事理论研究服务,但军事学术研究存在着研究群体优势和合成作战理论优势发挥不够的问题。因而,要高度重视军事学术研究人才培养,加大经费投入,强化军兵种之间合成作战理论研究的力度。  相似文献

抛锚式教学把学生设于真实的情境中,让学生达到认知冲突,让学生自己去分析问题、学习解决该问题所需的知识,逐步地解决问题。作为教师职前教育的一门重要的基础课程教育学,其教学效果一直不尽如人意。而抛锚式教学法为教育学的教学模式改啦提供了一种新的思路。  相似文献

Firms form various alliances or use brand extensions to enter new markets in order to improve their operational efficiency and create a positive spillover. However, they do not always know the implications of these strategies for market entry and multimarket competition because the sale of products in one market can have negative spillover effects on product sales in other markets. We present an analytical framework to examine whether and how (i.e., by choosing alliance entry or independent entry) competing firms should enter a market in a situation where market spillovers occur when a firm enters a spillover-producing market to sell products that may increase or decrease the consumers' willingness to pay for products in the primary market. Our analysis shows that the operational efficiency (or quality differentiation ability) of firms in a spillover-producing market varies, and hence, the impact of market spillovers differs for firms. We identify the key factors, such as bargaining power, brand value difference in the primary market, and the extent of efficiencies and spillovers, that determine the firms benefitting from the different entry strategies. Specifically, we show that firms would be more willing to choose an alliance strategy to enter a spillover-producing market if the negative spillover is small and alliance efficiency is high. In contrast, if an alliance entry is not favored, the firms' relative operational efficiency is crucial for them to decide whether to enter the market independently under moderate spillover conditions. Finally, we show the implications of market entry strategies for managers.  相似文献

Egypt plays a pivotal role in the security of the Middle East as the doorway to Europe and its military expenditure reflects its involvement in the machinations of such an unstable region, showing considerable variation over the last 40?years. These characteristics make it a particularly interesting case study of the determinants of military spending. This paper specifies and estimates an econometric model of the Egyptian demand for military spending, taking into account important strategic and political factors. Both economic and strategic factors are found to play a role in determining military burden/spending, with clear positive effects of lagged military burden, suggesting some sort of institutional inertia, plus negative output and net exports effects. The strategic effect as a result of the impact of Israel’s military burden is mostly positive and significant, though its impact is reduced when the impact of important strategic events are taken into account. The military spending of Egypt’s allies Jordan and Syria generally seems to have had no effect on Egypt’s spending. These results are consistent over a range of econometric techniques.  相似文献

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.  相似文献

A combination of threat analysis and “subterranean forces” (such as proclivities to fight conventional wars as compared to asymmetric ones) leads the USA to prefer focusing on the threats from China rather than those emanating from the Middle East.  相似文献

The evaluation and selection of military strategy requires consideration of myriad factors – social, historical, political, geographical and technological – together with vast uncertainties encompassing all these domains. Info-gap decision theory is a conceptual framework that can support these deliberations and that has substantive implications for the formulation, evaluation and selection of strategic goals and of the means to attain them. In particular, while the analyst may desire to reliably achieve the best possible outcome, info-gap theory provides a critique of, and alternative to, the paradigm of optimizing the outcome of a decision. In selecting between strategy alternatives, the analyst must sometimes choose between one alternative that is purportedly better than another, but also more uncertain. Such a choice is a dilemma whose resolution requires the analyst to balance between the different predicted qualities of each alternative and their different vulnerabilities to uncertainty. The dilemma can be managed with the info-gap methodology of robustly satisfying critical requirements.  相似文献

作为重要的全球公域范围与全球治理对象之一,太空既面临着日益严峻的资源、环境与安全问题,又不断彰显着其极具地缘政治意义的战略地位,攸关国家利益与安全。自进入太空时代以来,争夺和维持太空领域的领先地位一直是美国不懈追求的目标。美国的经济、军事等国家实力越来越依赖太空,同时其太空资产的脆弱性也愈发凸显。面对新的国际国内形势与外空态势的复合挑战,奥巴马政府适时调整了美国的太空战略。文章以全球公域和全球治理为切入视角,在分析太空领域全球治理现状的基础上,从太空活动行为准则的制定、太空国际合作的深入、太空军备竞赛的规制三个层面解读奥巴马政府的新版太空战略,并探讨其深层次的动因与影响,进而为中国参与太空领域的全球治理提供有益的理论支撑与现实参考。  相似文献
