美国尼克松政府大三角战略决策肇始解析——以第63号国家安全研究备忘录为中心

构筑美苏中大三角关系是尼克松政府的重大外交决策,它开始于1969年.在中苏边界冲突发生后,美国政府围绕第63号国家安全研究备忘录进行了详细研讨,全面评估中苏分歧对美国对外政策及世界格局的影响.经过多次讨论,美国政府内部基本达成共识,即构筑美苏中三角关系是最有利于美国的政策选项,要以灵活的态度处理三边关系,但不允许发生会导致核战争或世界力量对比出现重大改变的情况.

A CONSOLIDATED MODEL OF MONOCENTRIC CITIES AND AN EMPIRICAL ANALYSIS OF URBAN SCALES AND LAND PRICES IN CHINESE CITIES*

ABSTRACT Motivated by the newly established Chinese urban land markets, we develop a theoretical model that unifies the “closed” and “open” features of the classical monocentric city model. The model features interactions between permanent urban residents and migrants and exhibits a distinctive equilibrium pattern. The theoretical model is tested empirically, using recent Chinese city‐level data. The empirical findings indicate that market forces now play an important role in urban expansion and land price formation, while various forms of government planning are still influential. Our results show that migrants exert a less pronounced impact than the classical “open” city model has suggested.     

试述初中语文教学中对学生的感恩教育

在初中语文教学中,对中学生进行感恩教育主要通过联系实际,以学生由内而外的“内省”为突破口,将感恩思想中内省的自我发展要求,在学生内心中激发出来,变“要我学好”到“我要我学好”,找回学生内心人性的东西,真正促进学生的主体性发展。     

高庙文化及其对外传播与影响

高庙遗址的发掘和高庙文化的确立,是近十余年来中国南方新石器时代考古的重要收获之一。这类遗存以其鲜明的文化特征和浓烈的宗教艺术氛围而吸引着诸多业界学人,特别是一些敏感的民俗学家与从事宗教艺术研究的学者,他们在遗址发掘的全面报告还未出来之前,讨论就已很热烈了,由于各自的视角不同,当然难免纷争与歧见,但这种多视角的探索,是学术研究所推崇的。     

泉州老城区文化遗产保护对策研究

在21世纪,加快城市化、现代化建设与保护历史文化遗产的矛盾日益突出.历史文化名城是历史文化的重要载体,一个城市的历史文化遗产通常显示着这个城市既往文化创造的极致.泉州作为国务院首批公布的24个历史文化名城之一,是世界多元文化的汇合之地,而泉州老城区是泉州历史文化名城的最好见证.泉州高度重视历史文化名城保护工作,切实加强历史文化遗产的保护,成绩斐然,但也存在较多问题.研究采取相应对策乃是当务之需.     

中国传统文物观初探

传统文物观是中华民族数千年来形成并发展变化的对文物的思想认识。文物承载的历电记录和文化内涵使人们很早就意识到文物彰显着人类文明发展的进程。原始崇拜和祖先崇拜的玉器、反映宗法等级的青铜器、精美绝伦的瓷器、卷帙浩瀚的经史典籍、历代名家的书法绘画等丰富多样的文物皆蕴含着千年历吏积淀而未显题化的中国传统文物观,需要我们去理解和诠释。本文尝试对中国传统文物观的发端、形成进行探寻,就思想、文化、艺术、财富等方面在中国传统文物观中的反映略作剖析。     

From scholar to bureaucrat: the political choice of the historical geographer Zhang Qiyun

In the mid-1920s, under the guidance of his teacher, Zhu Kezhen, Zhang Qiyun established himself as a scholar by compiling middle school geography textbooks. He reached the peak of his early academic career when he joined the National Defense Planning Commission (Guofang sheji weiyuanhui) in 1932. His subsequent setbacks offered him a different kind of experience. During his tenure at Zhejiang University (1936–1949), he strived to combine research and administrative work. His friendship with Chen Bulei, Chen Xunci, and others, provided him with the connections to move from academia into politics. More important, beginning in the 1940s, Zhang contributed his scholarship in historical geography and geopolitics to the ruling regime and attracted Chiang Kai-shek’s attention. In 1948, some of the students at Zhejiang University started a movement to oust Zhang, which truly alienated him. During the power transition in 1949, Zhang made a political choice entirely different from the one made by his longtime mentor Zhu Kezhen, epitomizing the political divergence among scholars in the last years of the 1940s.     

Nonparametric Significance Test for Discovery of Network‐Constrained Spatial Co‐Location Patterns

Spatial co‐location patterns are useful for understanding positive spatial interactions among different geographical phenomena. Existing methods for detecting spatial co‐location patterns are mostly developed based on planar space assumption; however, geographical phenomena related to human activities are strongly constrained by road networks. Although these methods can be simply modified to consider the constraints of networks by using the network distance or network partitioning scheme, user‐specified parameters or priori assumptions for determining prevalent co‐location patterns are still subjective. As a result, some co‐location patterns may be wrongly reported or omitted. Therefore, a nonparametric significance test without priori assumptions about the distributions of the spatial features is proposed in this article. Both point‐dependent and location‐dependent network‐constrained summary statistics are first utilized to model the distribution characteristics of the spatial features. Then, by using these summary statistics, a network‐constrained pattern reconstruction method is developed to construct the null model of the test, and the prevalence degree of co‐location patterns is modeled as the significance level. The significance test is evaluated using the facility points‐of‐interest data sets. Experiments and comparisons show that the significance test can effectively detect network‐constrained spatial co‐location patterns with less priori knowledge and outperforms two state‐of‐the‐art methods in excluding spurious patterns.     

Give Me a Pot of Sweet Tea

For those who come to Tibet for the first time,butter tea is on their list to try.I, however,am an exception to the rule because butter tea just does not agree with me. I prefer the delicate fragrance of sweet tea but enjoy watching Tibetans light butterburning lamps and the serenity of the light from butter lamps in dimly lit monasteries. During my trip through the middle of nowhere on the plateau,we had a happy encounter with some herdsmen taking a break from their journey.
