中国特色社会主义在何处“显”特色

中国特色社会主义作为社会主义当前的主要实践形态,有着自己独特内蕴。从它产生的境遇来看,中国正处在由生存危机、制度危机和开放危机转向发展危机、体制危机和封闭危机的转折期;从它分析问题的立意来看,它具有鲜明的问题意识、浓厚的现实意识和兼收并蓄的对话意识;它在解决问题的着点上,既注重整体立意、全局着眼,又强调把握原则,灵活运用,着重创新,强调踏实稳重,分步按阶,彰显着中国特色社会主义建设与发展的协调性、自主性和阶段性。     

青海经济转折点理论与实践探析

改革开放30年来,全省经济社会发展取得很大成就,经济实力得到显著增强。当前,青海是否处在加速发展、加速起飞的转折点以及产业转型升级的关键时期？省内各有不同见解。本文对青海经济发展阶段进行综合分析和判断的基础上指出,目前青海经济正处于加速发展的重要时期,但还没有实现经济的加速起飞,并提出了促进青海经济加速发展和产业转型升级的战略选择。     

A geometric morphometrics-based assessment of blade shape differences among Paleoindian projectile point types from western North America

Blade shape features in the type definitions of Clovis, Folsom, and Plainview projectile points. However, the accuracy of these assessments has never been evaluated. Here we report a study in which geometric morphometrics and multivariate statistics were used to compare the shapes of the blades of Clovis, Folsom and Plainview points from the Southern Plains of North America. In the course of the analyses, we controlled for the impact of three potential confounding factors: allometry, differences in raw material quality, and resharpening. The analyses show that blade shape distinguishes Clovis points from both Folsom points and Plainview points, but does not distinguish Folsom points from Plainview points. The analyses also show that the similarities and differences in blade shape among the types are independent of allometry, raw material quality, and resharpening. These findings suggest that the type definitions for Clovis, Folsom and Plainview need to be altered. They also have implications for typing specimens that lack other defining characters (e.g. channel flakes, flutes). Lastly, the absence of resharpening effects raises questions about the validity of the reduction thesis.     

Using Airborne LiDAR Survey to explore Historic-era archaeological landscapes of Montserrat in the Eastern Caribbean

Abstract

This article describes what appears to be the first archaeological application of airborne LiDAR survey to historic-era landscapes in the Caribbean archipelago, on the island of Montserrat. LiDAR is proving invaluable in extending the reach of traditional pedestrian survey into less favorable areas, such as those covered by dense neotropical forest and by ashfall from the past two decades of active eruptions by the Soufrière Hills volcano, and to sites in localities that are inaccessible on account of volcanic dangers. Emphasis is placed on two aspects of the research: first, the importance of ongoing, real-time interaction between the LiDAR analyst and the archaeological team in the field; and second, the advantages of exploiting the full potential of the three-dimensional LiDAR point cloud data for purposes of the visualization of archaeological sites and features.     

Capturing spatial patterns of rural landscapes with point cloud

Over the past few decades, rural landscapes have been the subject of increasing international cultural heritage research, and one of the most important issues under investigation at both theoretical and pragmatic levels concerns how to identify the spatial character of rural landscapes for conservation purposes. This article establishes an innovative approach adopting a cultural landscape perspective with the support of point cloud technologies to capture spatial patterns of rural landscapes. This approach was explored by reference to Tunpu villages in Guizhou, China—these being a specific kind of military fortress settlement. Cultural landscape values and landscape characters of Tunpu villages were identified using historical research and document analysis. Aerial and terrestrial photogrammetry and laser scanning systems were combined to collect and process spatial information at environmental, village, and architectural scales. Point cloud models can quantitatively represent villages' spatial patterns and inform the interpretation of their heritage significance. We conclude that the strengths of point cloud technologies could meet the requirements of rural landscape heritage documentation from a cultural landscape perspective. This mixed‐technology approach could also greatly improve the efficiency and precision of traditional rural landscape documentation, which has the potential to change methodologies applied to rural landscape research and management.     

金圣叹所作“元晖”诗本事考——兼论清初戏曲家叶奕苞的生卒

在今存金圣叹诗歌中,有两首是为其友“元晖”而作。此人是昆山叶奕荃,早年入复社,为人重气义,清兵下江南后,曾多次冒险奔赴杭州接父还乡,后中道遇害,死于浙江嘉善。金诗《元晖来述得生事》等,即述说前此有关经历。奕荃弟奕苞,为清初戏曲家,生卒向无确考,今据确凿史料得知为1629-1686。     

论中国特色社会主义的历史起点

近年来学术界对中国特色社会主义的历史起点问题分歧较大,主要有1921年说、1927～1934年说、1956年说、1978年说、1982年说。产生分歧的原因很大程度上是由于对中国特色社会主义科学含义缺乏统一认识,问题的核心是如何理解马克思主义、科学社会主义基本原理与中国实际相结合,有必要在概念的使用上更加严谨和缜密,在研究层次和角度方面做必要的区分。     

基于POI大数据的资源型城市功能区识别方法与实证——以辽宁省本溪市为例

精准识别城市功能区对于优化协调城市人地系统，完善城市规划及促进城市可持续发展具有重要意义。选取公众认知度和地物一般面积对行业POI数据核密度进行加权，构建城市功能区定量识别方法，以本溪为例，输出城市功能区分布图并开展分析。结果表明：①考虑公众认识度与一般面积的核密度加权方法具有更高的实际性和准确性；②本溪市中心城区受地块大小、交通等因素影响，形成“多中心”组团、“单一-混合”功能区协同发展的空间格局。应进一步完善本溪新城区公共服务体系、优化旅游业产业链条，推进资源型城市转型进程。
