发达国家城市收缩现象及其对中国的启示

城市收缩是发达国家在工业化与城市化过程中普遍存在的现象,城市收缩对发达国家经济社会转型、城市空间结构转变产生了深刻影响,在对城市收缩有效治理过程中形成的精明收缩与弹性城市理论对快速发展的工业化国家具有积极的借鉴意义。本文对发达国家城市收缩的现象与事实进行了系统梳理与分析,分析了城市收缩的特征与空间模式,探讨了城市收缩的形成机制和城市收缩的应对措施,并对西方发达国家城市收缩现象对我国的启示形成了几点认识。     

黄河流域区域经济差异的时空动态分析

以黄河流域的各地级市为研究单元,人均GDP为测度指标,综合运用不同时空动态分析方法,在Open Geoda和Pysal2.7软件支持下,对1990-2013年黄河流域73个地级市经济发展水平空间格局和演变过程进行分析。研究表明:黄河流域整体区域经济差异呈现先扩大后减小的趋势,东部地区内部差异最显著对整体差异贡献最大,中部、西部区域经济差异相对稳定;流域经济空间异质性明显,存在显著的空间正相关,区域经济格局两极化明显且东部经济水平明显高于中西部地区,流域经济发展的热点区主要分布在山东省内,冷点区主要分布在甘肃、陕西、青海等部分州市;通过分析黄河流域73个地级市经济发展类型时空演变特征,反映出黄河流域经济发展存在俱乐部趋同趋势,初始状态对区域经济发展具有重要作用,区域背景亦具有一定作用,区域经济水平的跨越式发展基本不存在。

“元王诗”考索

自宋代以来,《汉书》所载元王诗多被人目为《鲁诗》,但其证据存在诸多疑点。因此,考察《元王诗》的归属是进一步地弄清汉代《诗经》传承版图的一个重要内容。本文从《元王诗》被看作《鲁诗》的过程出发,具体分析了《元王诗》非《鲁诗》的原因,并比对了刘向《诗》学观点与楚元王封地附近的汉代《诗》简,从而最终判定《元王诗》是汉代《诗经》传授中的独立一支,刘向所习主要是《元王诗》而非《鲁诗》。所以从刘向《诗》学中辑考的鲁诗也非《鲁诗》。     

瓷釉色彩语词的跨文化语义焦点——以青釉为例

在跨文化语境下,色彩词是怎样命名的?相近意义的色彩词有没有语义流变或焦点?同音异字的汉语色彩词组与色彩词的语义比较是怎样的?本文将探讨色彩词的建构与文化影响,使人们在不同文化语境下了解和探讨瓷釉色彩的深层含义,以便合理应用。     

Tactical Flexibility: Libyan Foreign Policy under Qadhafi, 1969–2004*

On September 1, 1969, a group of junior Libyan Army officers took control of the Libyan government in a bloodless coup d'état. After the coup, the group formed the Revolutionary Command Council (RCC), chaired by Muammar al‐Qadhafi. In the four decades following, Libya faced numerous foreign policy challenges. The Qadhafi regime took on a distinctly anticolonial flavor that mirrored the revolutionary political trends of Egypt under of Gamal Abdul Nasser. This change in foreign policy posture shook Libya's relations with the United States and the United Kingdom and initiated the degradation of Libyan–Western ties. Under Qadhafi's leadership, Libya chose an ideological path for that focused on the strengthening of sovereignty while pursuing policies of unity and anti‐imperialism. This often put Libya at loggerheads with the West, and at times with its neighbors. Nevertheless, Qadhafi maintained popularity among his constituency. ¹ His domestic fame was the product of a carefully constructed persona that gave him the charismatic appeal necessary to maintain leadership during the latter quarter of the twentieth century and into the new millennium. Publicly, Qadhafi highlighted the similarities between himself and Libya's rural working class. He lived in a tent, and wore modest clothing. He fancied himself a devout Muslim, and praised the wisdom of the Libyan masses. He connected with his constituency through rhetoric that illustrated the stability of his policies over time, and their connection to the ideas that originally made him popular. This argues that the source of Qadhafi's charismatic power lay in his rhetoric, which connected Libya's foreign policy decisions to his foreign policy vision, the basis of his charismatic leadership. Qadhafi articulated his foreign policy vision during his first major speech to the Libyan people in September 1969, and he referred to it time and again when speaking about major Libyan foreign policy decisions. To demonstrate, this article describes the basis of Qadhafi's leadership authority and defines the parameters of his vision. Then Qadhafi's rhetoric surrounding major shifts in Libyan foreign policy is analyzed to show its congruence with his foreign policy vision. The rhetoric surrounding the Libya–Egypt war, the end of Libya's Chad intervention, Libya's surrendering of the two Lockerbie bombing suspects to be tried under Western authority, and Qadhafi's denunciation of the weapons of mass destruction programs—all major shifts in Libyan foreign policy—demonstrate how Qadhafi was able to maintain a single message, and thus his authority, over his first 35 years in power based on values established in the early days of his revolution. The flexibility of his vision enabled Qadhafi to maintain authority, while tactically adjusting Libyan foreign policy positions.     

浙江瓯海出土一件西周青铜器腐蚀成因研究

为研究浙江温州瓯海M24墓出土的一件青铜器的腐蚀成因,采用扫描电镜（SEM）、X射线荧光光谱仪（XRF）、X射线衍射仪（XRD）、离子色谱分析仪（HPIC）等,对青铜剑腐蚀产物及其埋藏土壤进行了分析。结果表明,青铜剑已严重腐蚀,铜元素大量流失形成以锡元素为主的腐蚀产物。通过测量模拟瓯海土壤环境下的自腐蚀电位并参照CuH₂O体系的电位-pH图,推导出了浙江瓯海出土一件西周青铜器腐蚀反应历程。研究结果对类似出土文物有参考价值。     

“乞休”与“挂冠”:晚明弃官现象与政治文化嬗变

在明代君臣关系中,君权一直处于强势地位,并左右着官员进退。明中后期,这种情况出现了微妙的变化。时值万历朝出现大范围缺官,以京官为首的文官群体以此为契机,引发了群体性的致仕乞休现象,不惜以影响政府的正常运作为代价,孤立皇帝,从而扭转了在致仕问题上长期处于被动的局面,并由此引发了官员对于君臣关系、权力分配及仕隐哲学的再思考,影响了主流舆论的变化以及政治力量在中央与地方之间的转移等。这种主动弃官的现象所折射出的理性精神和反传统思想在一定程度上催生了晚明政治文化的进步因子,并为中国日后具有近代意义的民主政治发展奠定了基础。
