Due to the development of urban economy and the transition of the traditional industrial structure, many historic cities and towns both at home and abroad have witnessed a large scale "demolition" and abandonment of industrial buildings in urban renewal during last 30 years. Consequently, it has been leading to the discontinuity of urban cultural and historic context. The paper discusses and expounds the clas...展开更多

By analyzing several profitability measures of these 1PO companies from the third year prior to listing up to the fifth year post-listing, it is found that IPO companies' operating performances as a whole peak in the year of listing or the year preceding the listing, but exhibit a fall in post-issue profitability with the decline being most pronounced in the first financial year following the year in which the listing take place. Over 30% of these IPOs suffer a loss three years after the offerings. Deterioration of post-issue performance is found to be more severe for smaller finns, highly-geared companies, fast-growing enterprises, companies with lower ownership retention by original shareholders, and companies which have managed earnings upwards at the time of listing. These observations are consistent with the higher agency costs when firms go public and that managers have timed the issue at the peak of the companies' long-run performance. Further investigation confirms that IPO companies in general make use of income-increasing accruals to manage their earnings upwards in the year when they go public. The reversal of the accruals in post-issue years further exaggerates the decline in their profitability.展开更多

The results showed that: ① in the core area, the percentage of construction land incteased from 18.22% to 61.72%, and the percentage of agricultufal land decreased from 58.36% to 11.14%. And the fafm land was fragmented, and traffic connectivily was strengthened. The afea of garden land was reduced from 251.89 hm2 to 50.38 hm^2, and the landscape metric of forest land showed an inverted V-shaped curve. ②The year 2009 in four phases witnessed the greatest landscape fragmentation, both Edge Density (ED) and Ingest Patch Index (LPI) increased, and human interference enhanced the overall landscape complexity. Measures were fotmulated in terms of deaf development goals, optimized allocation of land resoutces, effective protection of ecological ted lines, and definite ecological responsibility, so as to optimize the urban landscape pattern.展开更多

This paper totes to carry out some methods, such as muhi.analysis statistics method, to specify the impacts of urban land use on urban transport system. Firstly, the choice of urban transport road network affected by the characters of urban land use layout is discussed Secondly, the promotion of urban public transportation affected by high-density concentrated land use pattern is demonstrated Thirdly, the impacts of urban city-size on transport system structure characters are expatiated Finally, the impacts of urban mater planning in Guangzhou on the layout of transport system are illustrated .展开更多

It is found tha t vacant ratio of samples in Guangzhou accounted for 20.94%, which is relativel y high. The authors argue that real estate industry of Guangzhou has made rapid progress, at the same time, people should not overlook the vacant commercial hou sing. It will benefit the sustainable development of the real estate industry of Guangzhou to carry out effective measures and actively to make use of present v acant housing.展开更多

But today, people can design a layout without addressing its environmental impacts on the environment. Documents of the regulatory urban have the role to control the urban development of a town, they act indirectly on the urban landscape, but what about the environment? Algeria like many countries in the world introduced an economy based on developing sustainable economy. It was officially pronounced with the promulgation of Law No. 01-20 of December 12, 2001 relating to the development and sustainable development of the territory, one of the objectives of this law is the protection, setting values and rational use of natural resources and preservations for future generations. Even with these initiatives but still certain deficiencies that may be identified by the difference between these urban planning instruments and negligence of the socio-economic component. In this context, the idea is to find a balance between present and future generations, between economic needs and ecological and cultural needs backup, between individual and collective interests. It is to develop new strategies and management laws and mastery of the environment.展开更多

It has become a necessity to negotiate between stakeholder objectives, the expectations of citizens and the demands of planning. It is desirable to involve the stakeholders and citizens from an early stage in the planning process to enable their different viewpoints to be successfully expressed and comprehended. Therefore, the basic aim of the study was how the MR (mixed reality) application is designed to encourage and improve communication on urban design among stakeholders and citizens? In this paper, we discuss new approaches to visualize urban building and environment alternatives to different stakeholders and provide them with tools to explore different approaches to urban planning in order to support citizen's participation in urban planning with augmented and mixed reality. The major finding of the study is that learning "how these participatory technologies may help build a community of practice around an urban project". And throughout the different experiences, we can learn to assist towards development of a methodology to use the mixed reality as a simulation tool in the enhancement of collaborative interaction in real-Egyptian project. So, we can determine a number of recommendations to deal with new participatory design tools for urban planning projects.展开更多

Given the level of income made by economic entities and according to such correlation, their propensity to save can be generated. As a clear reflection of the development of the financial sector, insurance companies as financial intermediaries, through the mobilization of savings, contribute to the development of the entire financial sector. Analyzing the performance of insurance companies in Serbia, CARMEL method will be applied, which includes indicators for the presentation of quantitative criteria for the purpose of monitoring and analyzing the profitability of insurance companies consisting of a model that is the current methodology of the MMF. In addition to traditional financial instruments, derivative securities are traded in financial markets, promoting the development of financial markets, such as options, which are generators of potential growth of profitability. The aim of this paper is to show the growth potential of profitability in insurance companies, as well as decreasing risks which are connected to the business activities by the use of options.展开更多

The paper investigates the activities of a small group of Italian wine producers and farmers within the agricultural landscape around Piacenza, and the way they influence the transformation of local urban and rural environments through either the application of the principles promoted by the Slow Food organization, or the creation of alternative “unofficial” strategies. Through the analysis of documents relating to the past and present history of the agricultural territory around Piacenza and its material culture, the presented study aims to understand how historically consolidated contexts are physically transformed through food culture. Considering historical and economic works on the Italian agricultural landscape, the paper stresses the dichotomy between consolidated cultural practices acting on a historically traditional landscape, and the innovation coming from the subversion of those practices, by visualizing them through a qualitative-quantitative gastronomic map of the local territory.展开更多

The increase of urban informality is the most significant trend shaping the 21st century world. Furthermore, the urban informality "theory" should be considered in urbanization courses and development studies. With the rapid economic market development, changes mapped the major Syrian cities.

In consequence, a detonation of urban sprawl placing random districts and informal settlements around the city (elmokhalafat & elmanatiq elashwaiya) Damascus urban informality is a way of supplying shelters and houses as a fundamental human need. The study hereby high-lights the informal phenomenon and its effects on the city at present through analytical study showing solutions and asking questions, and, finally, deals with informality in an urbanized way with self-help constructs and upgrades to aid the low income and urban poor.展开更多
