Investigation on modern history of urban planning in Iran shows that there are three approaches in the subject under discussion: “Modernism and Westernism”, “Traditionalism and anti-Westernism”, and “Adopt and Adapt”. Proponents of the first approach believe in encouraging methods to use the external concepts. The second, is the idea about ​​cultural and religious values, ​​thereby everything with nontraditional orientation is rejected. In the third approach the thinkers believe that if the parts of tradition are synthesized by modernity, culture and religion can adapt themselves with the development. The purpose of this study is to evaluate the adaptation of traditional urban design patterns of Islamic-Iranian cities in incompatible district of new Iranian cities (spontaneous settlements) and to focus on the application of the third approach in the current situation of Iranian cities. On this basis, the method of comparative analysis has been applied to survey the differences and similarities between historical districts and spontaneous settlements. Studies show that there are rather similarities among physical - spatial parameters (such as structural and environmental criteria) between the two types of districts; because both of these residential districts formed as organic structures that are unstable against unexpected risks and earthquake. However, there are the differences between these two types of districts in organized and formed periods. Despite historical districts that have been consolidated and organized during hundreds of years, spontaneous urban textures formed quickly and without any plan and planning. Meanwhile, the historical districts have usually integrated townscapes and unique materials such as clay, bricks or stone, while this character (integrated townscape and unique materials) never have been seen in the spontaneous settlements. There are similarities in economic and socio- cultural characteristics between residents in the two the types of districts. The residents living in poor economic condition, but under a very strong socio-capital and traditional beliefs; There can be seen several socio-cultural and particularly religious characteristics in people of historical residential districts that are similar with the spontaneous residential places, such as “strong relationship among families, friends”, “hospitality”, “mutual relationship among family members”, strong religious beliefs and the needs for privacy and security. However, these communities are different in some principles such as quality of life and spatial and physical qualities especially in favorable and beautiful urban landscapes. So it can be extracted and adopted excellent principles from traditional and historical districts and adapt them to the inappropriate modern urban districts. With regard to the existence of these similarities, we explain applicable principles of the spatial characteristics and designing quality in the historical district of Yazd to apply in Baghshater District in Tehran as a spontaneous settlement. Findings show that we can use several solutions to reconstruct this zone included: 1) land readjustment as the suitable solution in Baghshater District with regard to the familial residential pattern in historical zone of Yazd such as Fahadan District. 2) Focusing on the traditional concept of mutual relationship in residential houses. 3) Emphasizing on the hierarchy of The entrances and exits of the residential units.

The electronic industry suffers a rapid changing and highly rival environment. Thus, firms have an essential need to strive for acquiring the competitive advantage. Strategy Organizational Agility (SOA) is a tool which enables to assist firms to attain the competitive advantage. Therefore, this study benchmarks the core competencies from a case study within the supply chain network and establishes a set of attributes for augmenting SOA. A novel multi-criteria decision-making structure is proposed to deal with the complex interrelationships among the aspects and attributes. Radial basis function (RBF) neural network can use linear learning algorithm to complete the work formerly handled by nonlinear learning algorithm, and maintain the high precision of the nonlinear algorithm. However, the results of RBF would be slightly unsatisfactory when dealing with small sample which has higher feature dimension and fewer numbers. Higher feature dimension will influence the design of neural network, and fewer numbers of samples will cause network training incomplete or over-fitted, both of which restrict the recognition precision of the neural network. The competence and accountability indicators can the continuously increasing level of agility to be effective. According to the analysis chart production and product design performance indicators alone cannot level a considerable amount of agility to change. But reducing the level of the index level of agility is reduced. Flexibility indices speed and agility level changes can also affect the organization. But with increased levels of these two indicators increased agility rate change indicators will be more flexibility. The results showed that customer knowledge management impact on organizational agility and organizational effectiveness and customer knowledge management through organizational agility has significant positive impact on organizational effectiveness. Finally, some practical suggestions, future research suggestions and research limitations are presented.

This study aimed to identify and test expectancy motivational model as a theoretical framework to explain the reasons motivating expected information consumer’s behavior for the selection and use of document delivery services of Shahid Chamran University, Ahvaz. In this study, explanatory survey method was used. In order to test the hypotheses and analysis of model’s data, covariance structural equation model-driven approach was used by Amos software version 23. Findings of analytical study shows that information consumers motivational model focusing on the three paths of expectancy, instrumentality and valence, and on the basis of the VIE model, is able to explain information consumers’ behavior in the document delivery services of Shahid Chamran University; therefore, the VIE model in this study was confirmed. Also according to the proposed table (Newstrom & Davis, 1968), motivation level of information consumers in their behavioral motivation to use document delivery services of Shahid Chamran University of Ahvaz was predicted to be average.

With emergence of urbanism, complication of urban community system, and occurrence of urban problems, a new paradigm of urban management was introduced that adopted new methods to involve citizens in policy making, planning, and supervision and direction of urban life. Therefore, the main element in managerial methods is involving citizens in urban life. Among the ways to make urban residents into real citizens is training an informing them. What everyday life suggests is everydayness. Everyday life is the very everyday life that is spent on repeated and everydayness activities such as work, rest, commutation, shopping, which all are boring and follow a predictable procedure. Urban spaces inevitably are background of large part of citizen’s everyday life, and therefore, undoubtedly interact with it, which means they both influence and are influenced by the individuals’ everyday life. This paper aims to collect and analyze literature on such interaction. Relation between urban space and everyday life has different aspects. However, they are placed between two contrasting ends, and tend towards one of them: everydayness and daily life; the latter of which suggests creativity, vividness and efflorescence of everyday life. Such life leads to lived experienced and creative moments for an individual, contributing to his/her balanced development. Such life, in the first place, realizes in a space which has individuals actively involved in its production and protection; and formation of such space has not been formed to impose dominant system’s values and rules on individuals. It is only in such space that physical and social dimensions of space are aligned, and spontaneity and efflorescence of urban life realize. It is in such space that diversity and individual differences are maintained at the same as keeping social sustainability. In other words, it is in such space that one can attain the right of being: one can live irrespective of his/her economic status, sex, education level, etc. In such space, individuals’ human rights in terms of access to urban requirements are observed and are subject to justice; people have the right to choose between proactive involvement in collection actions, and interactions, and retirement and relaxing from burden of urban life; collective memoirs of city are formed, and in addition to “form”, the space will acquire a “structure”, which remains in the people’s mind as a common thing. Memoirs that are embodied again as they are recollected, and as Agness Heller’s said, are reviewed in quiet and peace. Such review sets human mind free of sinews of everydayness, and directs towards criticism of the surrounding world. This paper was conducted using description-analytic method. Data collection was carried out using library (documentary) and field methods. This paper tries to study challenges and consequences of training of citizenship and relationship between urban space and everyday life.

The aim of this study was to investigate the role of coach-oriented organization and team performance in the mental health staff General Directorate of Youth and Sport of Ardabil. Descriptive and correlational methodology has been applied to the target and the field was done in this study population all staff General Directorate of Youth and Sport was Ardabil province in the number of them 85 persons. Limited due to the small population size of the population sampled and analyzed, so is the population size and sample size. To collect data from questionnaires in coach-oriented organization and team performance staff (researchers) and mental health (Goldenberg and Hiller, 1979) was used. To analyze the data descriptive statistics (frequency tables mean and standard deviation) and inferential statistics (Pearson correlation and multiple regressions) is used in which the coach-oriented organizational relationship with the staff in mental health and team performance The SPSS19software were analyzed. The results showed that between team performance and organizational staff coach-oriented relationship (r = 0.314), there was a significant (p <0.05). Inter coach-oriented physical and mental health relationship (r = 0.352), there was a significant (p <0.05). Inter coach-oriented and anxiety, social dysfunction and depression there is a significant negative correlation (p <0.05). The mental health of a coefficient of 88% could predict the coach-oriented organization.

Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde data give a fairly comprehensive vision regarding the occurrence of such phenomenon. In this study, the incidence of moderate to severe hail is investigated in the period of 1990-2010. First, the atmospheric codes related to hail phenomena were applied to extract the data, then radiosonde data in intended time were received and applying the RAOB software, the physical status of atmosphere was studied. In the studied period, two hail examples were reported on November 27, 2008 and December 5, 2008. In the first instance of hail that occurred on November 27, 2008, the status of some indicators was calculated and it was found that LCL was at an altitude of 284 meters, CCL at an altitude of 1582 meters, LFC at an altitude of 6230 meters, the ice surface at an altitude of 3278 meters, the LI index was -0.2, the K index was 25.7 ° C, and PWC was 28 mm. In the above mentioned conditions, there was a hail with a diameter of 25.4 mm. In the second instance of hail that occurred on December 5, 2008, the status of some indicators was calculated and the results showed that LCL was at an altitude of 280 meters, CCL at an altitude of 1762 meters, LFC at an altitude of 2271 meters, the ice surface at an altitude of 2771 meters, the LI index was -1.4, the K index was 27.1 ° C, and PWC was 23.6 mm. In the above mentioned conditions, there was a hail with a diameter of 3.6 mm. Given that in many ways, the status of most atmospheric indicators in the two above examples of hail were close to each other, it turns out that in similar circumstances, the greater the distance the ice level gets to the summit of cloud, the greater is the probability of hails larger in diameter. The value of this distance for November 27, 2008 was at approximately 6384 meters and for December 5, 2008, it was at about 5012 meters.

The rights of citizens to provide Social justice, due to emphasis on the basic needs of human beings, known as one of the most fundamental principles in international documents of human rights and civil rights. It's indicators include the right to a fair life, right to health, right to education, right to social security, and right to work and employment, which in human rights documents, particularly in the International Covenant on Economic, Social and Cultural Rights, regarded as the second generation of human rights. Social justice, who has been noted specifically in the first, third and fourth chapters of Constitution of the Islamic Republic of Iran, are the same components that have been identified in international documents of human rights. These indicators will realize when all citizens have equal opportunity to take advantage of it. The government's obligation to support these rights is positive, and an obligation to urgent results and in some indicators the obligation of result, is increasing.

In last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can therefore, be more informative than the Boolean technique. The objective of this study is to apply fuzzy set methodology in the context of a decision making process known as the Analytic Hierarchy Process (AHP) to land evaluation for irrigated wheat. The results revealed that the results obtained with fuzzy AHP method are in better agreement (R2=0.911) with the observed yield as compared to those obtained with parametric method (R2=0.804). Although, the fuzzy AHP provided more efficient and accurate results than parametric method, the choice of membership functions, width of the transition zones and weight values are determinant to achieve its realistic results in land suitability assessment.
