新媒体对藏族民众文化生活的影响调查研究

研究以青海省城镇、农业地区和牧区的270名藏族民众为被试,通过对藏族地区新媒体普及情况、使用新媒体的能力以及藏族民众喜欢的媒体资源类别等方面进行调查,分析了中国移动和中国电信网络、智能手机、数字广播电视、计算机及其网络给藏族民众的生活带来的影响,并提出通过加大适合于藏族民众的媒体资源建设力度,转变思想,提高服务意识,建设一个方便访问和传播的藏语信息技术平台,发挥新媒体在基层党员干部培训中的作用,以村为单位实行数字广播电视的统一管理,尽早尽快做好光纤的村村通工作,进一步降低手机资费标准,减轻藏族民众的通信负担等改进策略。

雅典奥运会的交通规划、模拟和管理

一、导言 为奥运赛事规划和管理交通设施是一项非常复杂而又艰巨的任务,几乎所有主办城市都面临着十分严峻的交通问题,要考虑为不断增长的交通需求提供可以接受的服务.为了组织好由于奥运赛事而在时间和空间上所集中产生的交通量,必须事先进行大量系统而又周密的研究工作,并且要对现有交通设施进行合理的改善.     

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.
