利用“幼儿园家庭教养方式调查研究”基础数据,本研究从家长参与家园合作活动的频率、内容和方式三个维度考察家园合作中父母的参与程度问题,研究表明新疆兵团s市家长参与频率非常低,参与家园合作活动的内容单一,呈现出不平等的单向交流方式。同时,研究认为幼儿园性质是影响家园合作中父母参与程度的重要因素,而家长族别、文化程度和家庭户籍状况与家长参与程度无显著相关。最后,研究分析了家园合作工作中幼儿园与家长之间的关系,提出公办幼儿园和民办幼儿园促进家告参与的教师理念与策略,使家长参与更具实效性。 相似文献

We analyze strategic relationships between buyers and sellers in markets with switching costs and dynamic uncertainty by investigating the scenario wherein a representative buyer trades with two foreign sellers located in the same foreign country. We show that, under exchange rate uncertainty, switching costs may lead to switching equilibria where both sellers co‐exist in the market with the buyer, or no‐switching equilibria where either seller captures the market. The presence of exchange rate uncertainty facilitates competition by allowing the sellers to co‐exist in the market with the buyer. However, if the level of uncertainty is beyond a threshold, the only viable equilibria are those where one of the sellers captures the market. Further, depending on the level of exchange rate uncertainty and the sellers' variable costs, switching costs may either raise or lower the level of prices in long‐term contracts between the buyer and the sellers. © 2007 Wiley Periodicals, Inc.

This article examines Poland's national potential and its international position within the European Union (EU) with respect to security issues. It presents research results based on a comparison of Poland's national potential as it relates to other EU countries, which is useful when evaluating Poland's power within the EU. The article also evaluates Poland's crisis potential, i.e. it identifies those factors that may potentially be treated as threats to national and regional security. Finally, it enables the identification of challenges to Poland's security in the second decade of the twenty-first century. The research is conducted according to a multidimensional comparative analysis, which is perceived by the author as the best available to measure a country's power despite its weaknesses. 相似文献

In this study, we propose that in states with relatively weak central authorities, decision-makers had to develop market-oriented organisation solutions to successfully face a grave external threat, and these solutions proved to be efficient. Using an interdisciplinary approach that combines institutional theory, history and strategy, we analyse a case study, the use of corsairs (privateers) by England in the late sixteenth and early seventeenth centuries. We have found that the development of partnership companies went hand in hand for commercial and military purposes. English privateers proved to be economically efficient and superior to the centrally planned war operations of the Spanish empire. 相似文献

ABSTRACTChina’s efforts to build a ‘new type of great power relations’ and a ‘new type of military-to-military relations’ do not constitute a major turning point in relations with the United States. Political relations set limits on military cooperation, and the two sides have been unable to construct a sustainable strategic basis for relations. This has contributed to an ‘on-again, off-again’ pattern in military ties. Trends show a pattern of frequent disruptions in military-to-military relations from 2000 to 2010, followed by an increase in interactions beginning in 2012. Nevertheless, obstacles on both sides are likely to limit mutual trust and constrain future development of military-to-military relations. 相似文献
