This article analyzes some prospects for the economic and political development of the United States and China. The first part of the article is devoted to the consideration of strengths and weaknesses of the U.S. model and of the Chinese one. The second part of the article considers the most probable scenarios of the future struggle for world leadership. The first scenario suggests that China will continue developing at a faster rate in the several coming decades and will be gradually catching up with the United States in terms of Gross Domestic Product (GDP) production. However, after several crises in 2008–2020 the United States will likely regain a number of advantages over China as a result of assimilation of the newest technologies. The second scenario suggests that the United States will come across a whole range of internal social and political problems related to internal political splits. In this case, the United States will have to share its global leadership with China. The article attempts to answer the following questions: What scenario is more probable? Will the old world order change? What are the main conclusions for the European Union and for Russia? 相似文献

This research examined the development of the ability to differentiate logical from empirical problems and the different ways in which children solve these problems. Thirty-two 4- and 5-year-olds, thirty-four 8- and 9-year-olds, and thirty-five 11- and 12-year-olds were given five questions regarding an imaginary character’s predictions as to where a ball would land after being dropped through a ‘tautology machine’. The questions examined encoding and recall of problems, children’s understanding of when evidence was necessary, and children’s evaluation of form and evidence. Data were analyzed in two ways: (1) by comparing differences across participants on component questions and (2) an individual analysis examining the consistency of responses to component questions across the problem set. Overall, the results indicated that: (1) sixth graders tended to differentiate logical from empirical problems while preschool and third grade children rarely did; (2) young children tend to ignore both the logical connective and the second half of problems-termed a ‘cut;’ (3) these cuts are less frequent when a problem is compatible with one empirical possibility; (4) cuts do not stem from encoding or recall errors, but seem to be the product of incomplete problem processing and (5) from third to sixth grade, children’s understanding of logical form increased as the rate of cuts decreased. 相似文献

People are remarkably smart: they use language, possess complex motor skills, make non-trivial inferences, develop and use scientific theories, make laws, and adapt to complex dynamic environments. Much of this knowledge requires concepts and this paper focuses on how people acquire concepts. It is argued that conceptual development progresses from simple perceptual grouping to highly abstract scientific concepts. This proposal of conceptual development has four parts. First, it is argued that categories in the world have different structure. Second, there might be different learning systems (sub-served by different brain mechanisms) that evolved to learn categories of differing structures. Third, these systems exhibit differential maturational course, which affects how categories of different structures are learned in the course of development. And finally, an interaction of these components may result in the developmental transition from perceptual groupings to more abstract concepts. This paper reviews a large body of empirical evidence supporting this proposal. 相似文献
