The questions of centralization and decentralization arise in every polity. The constitution or the practice or both have to settle how much of policy making is to be decided by the central government and by component bodies. By and large liberalism and decentralization tend to go together while authoritarianism tends to be associated with centralization. The constitutional model which is generally regarded as bringing about the largest amount or decentralization is federalism. This is said to sonstitute a half way house between confederacies (where component units dominate)and unitary states (where the center dominates) In its classical form at least , federalism stipulates that there have to be two independent levels of government (the centre and upper level component bodies (often named states) each of these levels has the right to decide on matters falling within its own sphere. There are difficulties in practice especially with respect to the constituent power and to the fields allocated to each level. Federalism must be based on a rigid constitution there has to be s supreme court protecting the independence of the two levels of government there has to be a second chamber defending the rights of the component bodies at the central level.yet there are variations in the extent to which the component bodies are protected and generally in the extent to which there is decentralization. On the one hand federal states are becoming more centralized on the other centralization cannot go beyond a given point without leading to gross inefficiency and perhaps to a break up of the regime as the communist experience showed. Partly for this reason there is a degree of convergence between federal and unitary states. Federalism is also associated with efforts to bring together independent states but this has occurred in a smell number of polities only. Attempts at achieving closer cooperation between states has led more commonly to confederacies, such as the Unites Nations. The European community or European :::union::: has innovated by forming a type of association labeled supranational which is intermediate between the confederal and the federal models. There is innovation in that developments take place gradually with new fields beings progressively covered new structures being set up and new member states joining. The problems of centralization and decentralization have exercised the minds of many in relation to many types of organization : both efficency and freedom appear to be at stake . federalism succeeded in a number of contexts but it is not the panacea which some suggest it is it is also so diverse that one has to refer to federalisms rather than to federalism . what is at stake is the need to find an equilibrium between the two extremes of over centralization and break up. Given the large number of situations in the contemporary world one should look for a variety of solutions and for a continuous evolution of the models which have hitherto been proposed.

Background: This study aimed to identify factors contributing to the creation of intellectual capital in the organization of education. The research method is a descriptive and exploratory factor analysis method. A sample: directors and deputies of the second period Secondary Education Department of Tehran Province. Based on stratified random sampling method and based on a sample of 500 was calculated size formula. The research made questionnaire constitutes a measurement tool through which factors in the creation of intellectual capital was identified by the sample. Validity to help them with the help of factor analysis and reliability was confirmed by Cronbach's alpha equal to 78/0. And finally analyzed by factor analysis of main components were analyzed. The findings suggest that the amount of KMO is close to 1 is equal to 881/0. Bartlett test of sphericity is also characterized by a significant level of zero, which is smaller than the 05/0 show statistically significant. And the final outcome of the 9 extracted with PC using varimax rotated in total by performing factor analysis identified nine factors: Self-conscious, value-based and central vision, holistic and systemic approach, independence, spontaneity, sense of mission, altruism, accountability, change frame of mind Factors identified in order to create intellectual capital could have a significant relationship with the studied variables. So successful, in order to strengthen each of these factors will lead to the creation of intellectual capital in educational organizations.

Current article is allocated to the report of a research in which the income elasticities of urban families” demand for public education in time period of 2008-2013 were estimated separately according to the income deciles and by applying Rotterdam Demand System, it was clarified that public education is normal commodity. Different size of estimative elasticities indicated that public education is necessary for the families belonged to the sixth and tenth income deciles and it is lux for first to fifth income deciles and it can be expected that if the income of families belonged to the first to fifth deciles faces with reduction, mentioned families for one percent reduction of income will reduce their demand for public education more than one percent and they will consume the related sources for necessary commodities and services. In contrast, the families belonged to the sixth to tenth deciles reduce the share of lux commodities and services in their cost basket so that not to be forced to reduce their public education costs proportional with income reduction. Therefore, the effective policies on families” income should be compiled and executed in a manner that not to cause to reduce the demand of families for education and especially groups with low and medium income.

Urban spaces and in other words urban design and architecture have been found with close linkage with art and beauty especially the arts such as painting and sculpture. Addressing beauty at different areas such as creation of galleries to offer works of art, addressing form of urban spaces and representing works of art in urban environment have improved social life and increased identity, consensus and collective solidarity. On the other hand, it can provide an interesting and calm environment for the citizens and residents. Concurrent with the socio-political developments in the twentieth century and the progress of science and technology, all the areas of the arts were subjected to change. The metamorphosis of the art and stylistic developments took place and a large number of artists tended to innovative phenomena. Since the art at the twentieth century especially the second half of the twentieth century sought to affect the addressee, a group of the contemporary artists including sculptors have not known the tight enclosure of museums and galleries to represent their works and preferred to display their works at open space and wide and large places of cities. Representing works at open space requires largeness of dimensions of works at multiple scale and use of modern materials and techniques. Sol Lewitt (1928 - 2007) has been regarded among the artists at contemporary age at the area of Minimalism and Conceptual Art. American philosopher and theorist and contemporary art critic, Arthur Coleman Danto, has conducted articles in criticism to works by Sol Lewitt and has appeared in exhibition of his works. Lewitt made the earliest structures in 1965 and continued his activity at the 1970s by expansion of plans and planning for the larger projects which have been being made based on morphological and conceptual ideas. Ultimately his arrangements were proposed at huge scale and extended from the space of galleries and museums which tended to conceptual and minimalist art to the urban space. In the present research, works of this artist and ideas of Arthur C. Danto about minimalism and works of Sol Lewitt are analyzed. The main questions are as follow: What outcome representation of these works has in natural environment and urban space? how the border between art has removed the daily life and addressee?
