浅析园林植物配置

园林植物配置,又称植物造景或景观种植。植物配置在园林设计中起着非常重要的作用,在运用植物进行配置时,既要考虑植物配置的艺术要求,又要考虑植物配置原则,合理配置园林中的各种植物,以发挥他们的园林功能和观赏特性,创造出优美的景观效果。     

一些特殊区域绿地的植物配置

在园林绿化进程中,常常有一些不让人注意,而对环境的影响较大的区域,在此区域进行合理的植物配置,可提升整个园林空间的生态功能和观赏价值.庇荫地植物的配置应考虑太阳照射状况,研究庇荫地的水分状况,在人工庇荫地要选择抗污染能力强的植物.墙壁植物的配置的类型有攀缘型、悬垂型和随意型等.屋顶植物配置应注意研究地区性及特殊性,在配置植物层次上,要选择喜光植物种类.

Election forecasting: Too far out?

We consider two criteria for evaluating election forecasts: accuracy (precision) and lead (distance from the event), specifically the trade-off between the two in poll-based forecasts. We evaluate how much “lead” still allows prediction of the election outcome. How much further back can we go, supposing we tolerate a little more error? Our analysis offers estimates of the “optimal” lead time for election forecasts, based on a dataset of over 26,000 vote intention polls from 338 elections in 44 countries between 1942 and 2014. We find that optimization of a forecast is possible, and typically occurs two to three months before the election, but can be influenced by the arrangement of political institutions. To demonstrate how our optimization guidelines perform in practice, we consider recent elections in the UK, the US, and France.

Technologies in transition,policies in transition: foresight in the risk society

The emergence of formal Foresight programmes in science policy across Europe is examined in terms of government's response to the changes in, and especially the uncertainties of, contemporary innovation. The paper explores this through deploying Beck's notion of the “risk society”, asking how far Foresight can be construed as the management of new technologies by the transition towards the “negotiation state”. It shows how, through a discussion of the social management of new health technologies, a tension arises between the priorities and regimes of the new “negotiation” and those of the former “provident” (or welfare) state. The emergence of new technologies will be shaped by the institutional assumptions and processes operating within the different policy regimes.     

论区域经济的视域与关切——新冠肺炎疫情的启示

人们对现实经济的认识,实际上是被一定的范式承诺所“框定”的。范式承诺决定了观察和感受经济的视域境界,视域境界决定了人们所看到的经济世界图景。人们观察和判断经济现象并非只有一个永远不变的视域,视域实际上是多样的,而且是可能会发生变化的。新冠肺炎疫情突出显示了视域境界和社会关切的改变,如何产生巨大的社会性影响,决定着对社会经济的态势判断的思维倾向。在其影响下,区域经济态势几乎断然改变,进入了“另一个世界”。信息传播使得域际关切更为突出,各地区都希望增强信息透明度,作为进行政策安排和民心安定的重要条件。新冠肺炎疫情使我们更深切地理解供给侧结构性改革的普遍性意义。让整个系统的各个方面都更具内在活力、反应效能和责任担当,国家治理体系和能力才能实现现代化。经历这次新冠肺炎疫情之后,整个国家及各地区经济,将进入一个浴火重生般的新视域世界,关切取向必将有新的选择,值得区域经济学者们进行更深入的研究。     

Analysis of the cross-region risk contagion effect in stock market based on volatility spillover networks: Evidence from China

This article uses the stock market regional indexes of 31 provinces (include Province-level municipalities and Minority Autonomous Regions) in mainland China as a sample, and constructs an inter-regional volatility spillover network of China’s stock market based on the GARCH-BEKK model. Through network centrality analysis, Diebold and Yilmaz's spillover index method and block model analysis, we comprehensively analyze the risk contagion effect among different regions in China’s stock market. The empirical results show that: (i) The risk contagion intensity (risk reception intensity) in various regions of China’s stock market has a typical “core-periphery” distribution characteristic due to regions’ different levels of economic development. (ii) There are obvious risk spillover effect in China’s stock market, among which the economically developed regions along the southeastern coast of China, such as Beijing, Shanghai, Zhejiang and Jiangsu, are the main risk transmitters, while the economically undeveloped regions in the Midwest of China, such as Xinjiang, Xizang, Gansu, Nei Menggu and Qinghai are the main risk receivers. (iii) Each region is divided into 4 blocks according to their respective roles in the risk spillover process in China’s stock market. Block 1 that is composed of the economically underdeveloped regions in the Midwest is the “main benefit block”, it acts as a “receiver”. Block 2 that is composed of regions with strong economic growth vitality in the Midwest is a “Bilateral spillover block”, it both plays the role of “receiver” and “transmitter”. Block 3 that is composed of developed regions along the southeast coast, it acts as a “transmitter”; Block 4 that is composed of the relatively fast-growing regions in the Southwest is the “brokers block”, it serves as a “bridge”. The results of this article can provide some reference for investors in financial institutions and decision makers in financial regulators.     

Financial risk taking in the presence of correlated non-financial background risk

This paper characterizes the stochastic deterioration resulting from taking a zero-mean financial risk in the presence of correlated non-financial background risk. We show in particular that it has an equivalent stochastic order as well as a necessary and sufficient “integral condition” that implies and is implied by a particular sense in which the stochastic deterioration can be decomposed into a “correlation increase” and a “marginal risk increase”. We further characterize a measure of aversion to the stochastic deterioration. These characterizations provide for a more general framework for formulating concepts of increases in risk and correlation and for better understanding risk management decisions governed by individuals’ attitudes to them.
