The discussion is based on a questionnaire survey conducted in 2011. This research concluded that more residents were satisfied with the housing unit features than those who were dissatisfied, while some remarkable differences could be observed if comparative analysis between two different public housing types in China were studied. The affordable housing residents are generally more satisfied with housing unit features than those living in low-rent housing. The most dissatisfying feature is the living room, followed by unit size and the floor plan. Additionally, the living room and the floor plans were features which were highly and positively correlated to the residents＇ overall satisfaction of housing unit features. Consequently, improving the living room size and the design of housing unit floor plans would clearly be beneficial to alleviating residents＇ dissatisfaction to the housing units.展开更多

Pension dual track the biggest drawback is that a significant loss of fairness, the gap between different groups of pension is too wide, causing social conflicts. The merger of the pension has be imperative. Therefore, it is necessary to establish and perfect the system of the civil service pension insurance legal mandatory occupational pension system, strengthen the basic social pension, broaden the channels for pension investment, reform organs and institutions pension system and pension system Retbrm and civil service pay rise, in order to promote the reform of the civil service pension system. The merger of the pension reform is scientific and reasonable, healthy and orderly and can achieve a smooth transition.展开更多

The value of these clauses may be important and should be added to the total value of the concession. However, in these cases, traditional valuation techniques, like the NPV （net present value） of the project, are insufficient. An alternative methodology for the valuation of highway concession is one based on the real options approach. This methodology is generally built on the assumption of the evolution of traffic volume as a GBM （geometric Brownian motion）, which is the hypothesis analyzed in this paper. First, a description of the methodology used for the analysis of the existence of unit roots （i.e., the hypothesis of non-stationarity） is provided. The Dickey-Fuller approach has been used, which is the most common test for this kind of analysis. Then this methodology is applied to perform a statistical analysis of traffic series in Spanish toll highways. For this purpose, data on the AADT （annual average daily traffic） on a set of highways have been used. The period of analysis is around thirty years in most cases. The main outcome of the research is that the hypothesis that traffic volume follows a GBM process in Spanish toll highways cannot be rejected. This result is robust, and therefore it can be used as a starting point for the application of the real options theory to assess toll highway concessions.展开更多

This aim is the result of a long discussion that has led to consider the public communication as a fundamental instrument supporting the dialogue between institutions and citizens and the result of an important sociological debate. Communication is nowadays considered as a structural element of Union＇s programs, and the transformation of the media system, the possibilities of communication offered by the social media, and the growth of participatory cultures have opened new ways to the development of European public communication that can contribute to increasing the European public sphere. This process involves an awareness from institutions and their representatives on the use of social media （e.g., Facebook, Twitter, etc.） to improve the relationship with the citizens and to create a sense of belonging to Europe.展开更多

The authors consider the following biharmonic equation:{?~2u = λ(1 + u)~p in B,u =?u/?ν= 0 on ?B, where p >n+4/ n-4and ν is the outward unit normal vector. It is well-known that there exists a λ*> 0 such that the biharmonic equation has a solution for λ∈ (0, λ*) and has a unique weak solution u*with parameter λ = λ*, called the extremal solution. It is proved that u* is singular when n ≥ 13 for p large enough and satisfies u*≤ r^(-4/ (p-1)) - 1 on the unit ball, which actually solve a part of the open problem left in [D`avila, J., Flores, I., Guerra, I., Multiplicity of solutions for a fourth order equation with power-type nonlinearity, Math.
