Faced with this fact, how are architects to responsibly pursue the act (and art) of building without further deteriorating the planet's environmental make-up or depleting its resources? What forms of high and low technology can be developed to curtail the injurious side of building? Can good or even great architecture be sustainable? In this paper discuss the problem such as: The Future Is Green: Architecture + Sustainability and have been surveyed Green Architecture and impacts of it on urban planing and urban design.

Earnings management has inverted the main objective of financial reporting through the distortion of the actual economic performance of companies and prevented the complete transfer of information to market. Given the importance of subject of research, incentives that cause earnings management have been reviewed from various aspects. The main purpose of this research is to examine the relationship between competition in industry and pricing power at product market and earnings management in the companies listed in Tehran stock exchange. For this, modified Lerner index was used to measure pricing power and three middle Lerner indices including industry, reverse number of firms in the industry, four-firm concentration ratio were used as the indices of competition in industry. To measure earnings management, Modified Jones Model was used. The statistical population consists of all the firms listed in Tehran stock exchange. With regard to the considered criteria, 100 companies among 9 industries were selected as sample based on two digit ISIC codes. Findings of research indicate that the companies which enjoy the pricing power at product market less likely manage their earnings. Another finding indicates that earnings management increases by increasing competition in industry. Hence, the investors who intend to invest in competition industry should pay more attention to earnings management.

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?

Today, there is a growing trend towards qualitative research in different areas of academic investigations. However, students face difficulties in deciding on qualitative methods of research, because most of the literature on qualitative research focuses on the philosophical and theoretical aspects, and they hardly offer any practical guidelines. This problem is rooted in the essence of qualitative research, which makes the details of the research process unachievable at the beginning. As a result, the features of the sampling plan—like the accurate size and form of the sampling—remain uncertain until after the data has been gathered, and this makes the jury doubtful about the approval of the research proposal. Hence, framing an appropriate and assayable plan for sampling can be of great help in the approval and execution of qualitative research plans. From this perspective, the present article aims to design a framework for a sampling plan in qualitative researches using theoretical sources of the grounded theory method and researchers’ suggestions based on practical involvement, as well as the recent experience of the authors in grounded theory research. By studying these sources, and considering the feedback for and practical involvement in the grounded theory method, a two-stage plan of sampling is proposed. The initial stage aims to ensure adequate diversity for the appropriate distribution of the samples, and the second, as a theoretical sampling stage, guarantees the theoretical attribute of sampling in qualitative research.

Participation of people in their cities and neighborhoods has always been emphasized by researchers and experts in order to improve the quality of citizens’ life and having efficient urban management. However, it seems that providing participation contexts at local level by citizens needs preparations and substrates that facilitate participation. In the meantime, establishing a neighborhood management plan in order to provide participation contexts at local level by citizens can be considered as a movement in this regard. Accordingly, the purpose of the present research is to evaluate the relationship between neighborhood involvement sense and social participation of citizens. In this regard, Kuti neighborhood of Bushehr, which has valuable activity, physical, and social features, is investigated as a sample. In the present research, the research method is operational based on the purpose and descriptive-analytical and experimental-surveying based on the method. Thus, library studies have been used to explain literature and history of the research subject, and field methods have been used to collect data according to the nature of the research. The data were collected by a questionnaire among 60 residents of the Kuti neighborhood who were over 18 years old. The sampling method, used in this study, was random and SPSS software was used for data analysis. The results of this research indicate that there is a relationship between neighborhood involvement sense and preparation for participation. The correlation between these two variables was in the positive direction. In addition, by increasing the neighborhood involvement sense, the preparation for participation increases.
