走，收房去

四五月份是交房的高峰期，作为名消费者，买房时我们面对的往往是精美的沙盘模型、宣传单和广告，还有能言善辩的售楼小姐。交了首付．贷了一大笔款，终于等到了收房的时候，兴奋总是难免，但往往会出现很多意料之外的问题，归根结底是没有一套完整的收房攻略。没关系，我们请来了雷青房产置换公司的刘洪光经理，让他来传授大家一套通行无阻的“收房神功”．有了这套收房攻略，你在收房时就会轻松许多！

收房全接触

先验房后交费、签文件的收房程序是较合理的正常程序，但开发商大多数采取先交钱填表、签文件，再验房的方法，这样开发商的主动性更大。因此，在收房时应据理力争。

2007年,房价回落的10大缘由

经过2004、2005年的层层洗礼,本以为2006年会是个整合之年,市场及时代的大潮却为中国房地产业带来了一系列暴风骤雨般的调控政策,但令人失望的是房价却坚挺如初。事实上,除了盼望房价能够尽早得到合理回落之外,大多数理智的人并不会希望看到房价大跌的一幕,因为那将比房价上涨带给社会的恐慌及影响更为严重。但是从众多角度分析,2007年北京房价将呈现回落之势。

政策/事件

北京规定业主2008年可先验房后交钱"先验房还是先交钱"一直是购房人和开发商在收房时发生纠纷的一个重要原因。为减少该类纠纷,北京市建委已经下发通知,要求预售的商品住宅在办理交接前,开发商要组织购房人查验房屋。

Comparative studies on phosphate ore flotation collectors prepared by hogwash oil from different regions

In order to compare the differences between variations of phosphate ore flotation collectors prepared by hogwash oils, JZQ-F collectors were prepared by the hydrolysis method using four types of hogwash oils from different regions in China. The components of the hogwash oils were determined using Fourier transform infrared spectroscopy(FIIR) spectra analysis, while the components of the JZQ-F were determined through gas chromatography–mass spectrometry(GC–MS). The flotation effects of the JZQ-F collectors were investigated by flotation experiments and the adsorption characteristics were determined through the quartz crystal microbalance(QCM-D). Results show that the JZQ-F collector from the Ordos area has 27.43% unsaturated fatty acids. JZQ-F collectors from Beijing, Qingdao, and Dongguan areas contain over 62% of unsaturated fatty acids, which can acquire phosphorous concentrates with a the grade of P_2O_5 above 31.96% and the recovery higher than 91.52%. These three collectors have a larger adsorption capacity, faster adsorption rate, and stronger adsorption structure on apatite surface, which contributed to a good adsorption performance and a favorable flotation effect.

China＇s Real Estate Tax Reform： Past, Present and Future

Since 1978, China＇s reform of real estate tax has made great strides with important milestones marked by the resumption of real estate tax collection on Chinese- funded enterprises and Chinese nationals. In the llth Five-Year Plan period （2006-2010）, the state administration completed the unification of tax rates for domestic and foreign- funded companies. However, the reform of real estate tax still requires many modifications during the 12th Five-Year Plan period （2011-2015）. The new plan should strive to streamline the tax system, adjust the tax base and tax rates, and delegate taxing authority.

Real-world characteristics of hospitalized frail elderly patients with atrial fibrillation： can we improve the current prescription of anticoagulants？

Background In elderly patients, especially those older than 80 years, atrial fibrillation （AF） is associated with an almost 25% in- creased risk of stroke. Stroke prophylaxis with anticoagulants is therefore highly recommended. The prevalence of factors that have been associated with a lower rate of prescription and adherence to anticoagulant therapy in these patients is little known. The objective of this study was to explore the clinical characteristics of elderly subjects, with and without AF, consecutively admitted to an acute geriatric unit, discussing factors that may decrease the persistence on stroke prophylaxis therapy. We also highlight possible strategies to overcome the barriers conditioning the current underuse of oral anticoagulants in this segment of the population. Methods A retrospective observational study was performed on a cohort of elderly patients with and without AF admitted to the Acute Geriatric Unit of San Gerardo Hospital （Monza, Italy）. Results Compared to patients without AF （n = 1216）, those with AF （n = 403） had a higher Charlson Comorbidity Index （3 vs. 2, P 〈 0.001）, number of administered drugs （4 vs. 3, P 〈 0.001）, rate of heart failure （36.5% vs. 12%, P 〈 0.001） and chronic kidney disease （20.6 vs. 13.2, P 〈 0.001）. Many patients with AF were frail （54%） or pre-frail （29%）. Conclusions Elderly patients with AF have higher rates of conditions that affect adherence to traditional anticoagulant therapy （vitamin K antagonists, VKA）. New direct oral anticoagulants （DOAs） can help overcome this problem. In order to prescribe the most appropriate VKA or DOAs, with the best efficacy/safety profile and the highest compliance, a comprehensive geriatric assessment should always accompany the scores for thrombotic and hemorrhagic risk stratification.

Rainwater Harvesting in Multifamily Social Interest Housing

This study evaluated the reduction of water consumption in a SIH （social interest housing） complex from the simulation of implanting a rainwater harvesting system. The methodology consisted of characterization of the case study, survey data of water consumption and data of precipitation in the area, on-site visits to define the average consumption and monthly water distribution, and sizing of a rainwater harvesting tank following the Netuno Program. It was obtained 22.500 L as the ideal volume for the tank, supplying the demand for drinkingwater in 32%, although the reduction in the drinking water bills would be minor, since the object of the case study is considered SIH, and residents pay a fixed fee for consuming up to 10 m3 per month. Therefore, it becomes necessary to analyze this situation from a sustainable and environmental perspective, and the benefits are no longer only economic, but rather they take on a more comprehensive social dimension.

Stock Performance of the Property Sector in Malaysia

Property investment in Malaysia is increasingly popular among local and foreign investors. The strong support by the government through the relaxation and lifting of certain restrictions and regulations on property ownerships, have attracted investments in the Malaysian property market. This research studies the factors affecting the performance of 36 property firms listed on the Main Board of Bursa Malaysia from 2003 to 2007. This research employed ordinary least squares （OLS） method to represent all the variables comprising stock performance, return on assets （ROA）, return on equity （ROE）, debt ratio （DR）, net profit margin （NPM）, effective tax rate （ETR）, earnings per share （EPS）, and price earning （PE） ratio. Results show that ROA, ROE, and EPS have strong significant relationships with the property stock performance. Although it is a small sample size, some relevant changes and modifications can be included in future studies to obtain better results.

Composite with Recyclable Loads for the Manufacture of Blocks to Build Popular Houses

The science space in a state school in Natal city was built using a composite consisting of gypsum, EPS （expanded polystyrene）, shredded tire, cement and water. Mechanical and thermal resistances were evaluated. Inside the blocks, three types of fillings （EPS plates, aluminum cans and 500 mL bottles of mineral water） were placed in order to obtain a walls with higher thermal resistance, but also to give it an ecologically correct order, considering that both the tire and the EPS occupy a large space in landfills and require years to be degraded when released into the environment. Compression tests were conducted according to the rules. The experiments demonstrated that the temperature difference between the internal and external surfaces on the walls reached levels above 12.0 ℃. It was also demonstrated that the proposed composite has adequate mechanical strength to be used for sealing walls. The proposed use of the composite can contribute to reduce the significant housing deficit of Brazil, producing popular houses at low cost and with little time to work.

The Influence of Displacement to the Success of Sustainable Multi-Storey Housing Development for Low-Income Society in Urban Area： Case Study- Multi-Storey Housing in Jakarta

Multi-storey housing for low income society is a concept of redevelopment from many alternatives of housing development for slum in Jakarta. However, redevelopment directly or indirectly leads to displacement of low-income residents. The new residents would be of a higher socio-economic status than the previous occupants. For controlling this phenomenon, a study about the influence of displacement to the successful of sustainable multi-storey housing development for low-income society has been done with descriptive method, observation and literature study. The result of this study give knowledge that displacement always happened when the quality of building and environment is increase, the location of multi-storey housing is near city center and commercial area. Low income society voluntary displaced their units to middle or high income society, because they are not affordable for paying operational and maintenance costs. The government has to make regulations for controlling displacement on multi-storey housing for low-income society and for the successful of sustainable multi-storey housing development in urban area.

Housing Policy in Khartoum： Plot Subdivision for Increased Housing Supply for Low-income People

The article discusses plot size standards applied in the government sites-and-services projects in Khartoum and probes into the possible alternative ways of re-establishing solid grounds for those standards. The particular issue of plot size is a crucial factor in the whole housing policy as it directly affects the urban land use and consumption and extends its influence far into sustainability and affordability issues and the whole housing policy and supply process. The article, analysing the applied standards, argues that plot subdivision can substantially contribute to providing more access of housing to the low-income groups. Large plot sizes can be subdivided driven by the need to realize security of tenure, doubling the owner-occupier housing stock which is the base issue of self-help housing, increases housing finance, provides variety of housing choices and behind all it conforms to the legacy principles and some cultural attributes of the local community. The article underlined existence of a cumbersome regulatory system, subdivision procedures and development controls which need to be reformed.

Roadway layout for recycling residual coal pillar in room-and-pillar mining of thick coal seam

In the context of a room-and-pillar mining gob in Shanxi province in China,this paper numerically investigates the stress distribution and deformation rules of roadway surrounding rocks at various locations of residual coal pillars in room-and-pillar mining gobs using software FLAC3 D.It is found that the concentrated stress beneath coal pillars distributes in a shape of ellipse.A reasonable roadway layout is then proposed.In this design,it is indicated that roadways should be designed to avoid the supporting zones of pillars with increasing compression and take into account the roof falling and crushing in the upper gob.According to the surrounding rock deformation characteristics and mining roadway locations as well as the supporting principles of timely support,rock reinforcing,piecewise management and suiting local conditions,a new asymmetric shield supporting plan is proposed.The field surveying results show that this supporting plan can effectively control the roadway rock deformation,thus guarantee the safe and smooth construction of roadways.

Recycling Plastics for Economical Housing

Abstract： The search for ＂new materials＂ to manufacture building elements for economical housing is the aim of this work. These materials are the following recycled plastics： Low-density polyethylene （LDPE）, recycled out of discarded soft drink packs： Polyethylene-terephthalate （PET）, recycled out of discarded soft drink bottles; and several plastics, from the printed films used like packages of candies （remainder of production plant by faults in the thickness of the films or in the inked process of themt. These conveniently grounded plastics were taken as ＂arids＂ to be mixed with Normal Portland cement, replacing heavy sand and gravel habitually used in these mixtures. These materials are used in constructive elements such as bricks, blocks and plates for economical houses closures or traditional construction. The developed constructive elements offer high thermal insulation, so they can be used in closures with a smaller thickness than conventional bricks and blocks. Besides, they have a lower specific weight than these traditiunal constructive elements. Recycling means lowering costs, making part of the environment contaminating waste useful and providing the unemployed and/or unqualified work force with jobs through uncomplicated technologies. Therefore, this recycling technology has an economic as well as an ecological purpose.

Standardization in Construction as a Tool to Reduce Cost of Housing for the Low-Income Families in Jordan

Providing a decent housing is a major challenge for governments and development authorities in Jordan and Arab countries. Nevertheless, the growing number of population falling under poverty put more demand on low cost housing options. The goal of the research was to find ways of rationalizing the cost and determine the appropriate standards and models that achieve an acceptable equation between cost and performance, and that during design and construction phases. The study follows the method of investigation and analysis to get factors that reduce the cost of the house construction for poor families by means of the concept of standardization in traditional （popular） buildings system. The research confirms that the traditional system has many advantages that could strengthen towards development a low-cost building system by applying the principles of standardization through architectural, structural and electro-mechanical considerations of design. Research recommends taking on studies for low cost building system through comprehensive analytical study of local building experiences.

Evaluation Research on Property Tax System in China

The reform of tax sharing system has made achievements from 1994 to now, but it also causes the lack of main tax category in local-tax system. Meanwhile, the disadvantage of property tax system in China exacerbates the dilemma of local finance, which can＇ t play the role of regulating real estate market. As the main content of real-estate tax reform, house property tax reform has been widely concerned and discussed since 2003. The paper analyzes the characteristics and disadvantages of the existing real-estate tax in China and the real-estate tax reform in Shanghai and Chongqing. The analysis indicates that the perfect real-estate tax has been established in China, but it is in the exploration stage.

Application of the Game Theory to the Real-Estate Market with State Assistance

The study of bilateral markets, in an equilibrium perspective, began to catch labor economists＇ attention in recent decades since they allow the prediction of market anomalies or flaws. In the study there appears a matching process whose theoretical analysis is known as bilateral assignment model. Among the different examples of bilateral markets and the assignment processes linked with them is the real-estate market. Its characteristics raise problems which affect low-income groups mainly, for which the state＇s mission is critical. These problems motivated the authors of the present work to provide a solution by using the results obtained in the assignment models with capacity restrictions. In this work the study is made of the real-estate market with the variant of the state intervention in housing assignment. The situation raised here is that the state has the task of facilitating low-income people access to housing so that they can participate in the real-estate market. In order to be able to fulfill its work, the state has a list of people willing to sell or rent homes thanks to tax cuts or some compensation offered by the state, for example. However, the state budget is limited and its participation will have a certain quota. Like the bilateral market, this new model solves the problem in which buyers and sellers are assigned to one another so that they can satisfy a property of stability. It is also shown that it is possible to find assignments for which there are no buyer-seller coalitions affecting such stability. A method is shown by means of which it is possible to solve the problem of truncating the benefits given to buyers and sellers under the emergency of budget cut.
