论王闿运《楚辞释》的政治化阐释及其影响

王闿运《楚辞释》着重从时世政治的角度解读《楚辞》,围绕屈原“兴楚返王”的愿望、“荐列众贤”的举措和所谓“款秦误国”的罪名三个重要政治节点展开。这种政治化阐释的背后有其纵横思想的主导和深刻的政治寄寓,并在客观上打上了求新尚奇的烙印,对其弟子廖平的楚辞研究产生了深远影响,在楚辞学史上掀起一股尚奇疑古之风,并推动楚辞研究朝求新求变的方向发展。     

重庆市融入国家“一带一路”战略的思考

重庆作为中国西部唯一的直辖市,是国家“一带一路”战略中承东启西、联接南北的重要联接点,具有极其重要的区位优势。依据重庆独有的发展优势,结合“一带一路”战略对重庆市“西部地区开发开放支撑点”的定位要求,提出了优化对外开放的良好环境、坚持“走出去”与“引进来”相结合、创新产业业态等方面的发展思路,以期实现对国家“一带一路”战略同重庆自身特点的深度结合,为将重庆市打造成为内陆开放的新高地提出可供参考的建议。

跳出地产看地产——试论滨海新区房地产的宏观走势

滨海新区的开发开放正式纳入国家战略已有一年,在此前后,滨海新区的房地产开发热已持续近两年.静观这两年的事态变化,开发者已由最初的喧嚣、癫狂而趋于理性,置业者和投资者浮躁的功利心态也逐步冷却.显然,坊间追捧和媒体热炒的房地产开发"盛世"并未如期而至;一些先行者创造的个案营销神话,似乎也未再现,惟一的奇迹,就是滨海的房价一再拉高,已经与中心城区比肩.滨海新区的房地产到底出现了什么问题?原因何在?需要有一个客观的诊断和解答.     

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study, a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions. Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and urban thermal conditions.

制度变迁背景下的社区权力与秩序——基于广州市一个城中村的研究

渐进的市场化和突发的制度变迁导致了城中村的权力格局和社区秩序发生了种种变化,居委会—村公司构成的权力结构及其互动关系目前已经成为城中村特有的"双轨制"权力模式,本文以广州市J社区为例深入分析这种双轨制的内在机制,认为社区内存在两种基于资源依赖基础上的循环链,由此带来了社区秩序的双重规则。     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.
