This paper describes a study in which the pattern of distribution of the number of friends among users of the Vkontakte social network among residents of eight large cities of the CIS (Moscow, St. Petersburg, Almaty, Novosibirsk, Tashkent, Kiev, Yekaterinburg, Pavlodar) was studied. Experimental data show that this distribution is of a similar nature for all selected cities. A semi-empirical model was built, on the basis of which an explicit form of theoretical dependence was obtained, describing the nature of the distribution of the number of mutual contacts (“friends”) of users of social online networks. It is shown that this theoretical dependence agrees with satisfactory accuracy with experimental data for a sufficiently large sample of cities. It is established that the Dunbar number, which is included in the dependencies considered as a control parameter, is a characteristic of the communication environment of each specific city and correlates with the population of the city.

The main theme of this article focuses on the study of the abandonment of neighborhoods or colonies that make up large cities in terms of the urban conditions that exist between its streets and avenues. In this case we refer to the América Norte neighborhood located in the east of the city belonging to the state of Puebla, Mexico. There are currently no adequate spaces for efficient pedestrian mobility, especially for the most vulnerable sectors such as the elderly, a sector that is the focus of this research. Therefore, the main objective is focused on carrying out a community management process that aims to offer strategies and actions to improve mobility conditions and pedestrian accessibility through citizen participation, all this with the collaboration of the board of directors, street representatives and institutions of the corresponding municipal government. The methodology used is developed from the complex systems from the action-research, in order to analyze and understand the problems from the social and urban environment that allows to broaden the perspective of the needs that reflects the social reality that exists in the neighborhood.

Transport systems are a major part and a key component of the city and its centre، and directly affect its planning and urban design. Integrated transport systems are considered as a fundamental reason of easy and possible accessibility of people، merchandise and others، as well as they appear distinctly in developed cities' centres، and to achieve such a targeted integration، the main bases must be provided. This study is emerged owing to the absence of a clear vision in our local studies about the integration of transport systems in the centres of large cities to achieve easy possible accessibility in a smooth and easy method، and also appropriate to the actual need for transport in a sustainable way to meet the social، economic and environmental requirements، such that many cities have developed plans to address traffic congestions in a studied approach. Therefore، the research problem is "the lack of a clear and accurate vision of the levels and ways to achieve the integration of transport systems in the centres of large cities، including the city of Baghdad". The research hypothesis is "integrating of different transport levels، contributes to build a sustainable city، and it is a guaranteed assurance to meet the immediate requirements of mobility and accessibility without compromising our communities' comfort in the future". Integration levels and their different foundations are the means to achieve integration to create easy accessibility and provide a sustainable environment by planning for the time being، and adopting sustainable systems in future plans. Thus، the importance of this research comes from the importance of transport systems and the foundations of their integration and their impact on the city planning to match the need for transport easily and in a way that promotes the social، economic and environmental aspects.

As our American cities struggle with the problems of growth and development, the human initiated disasters of crime and violence threaten the very existence of the urban core ofmost large cities. Los Angeles dominates the American crime scene with its gangs and drug dealers, where violent crime will strike one in every three Angelenos in their lifetime. The city is a leading example of environmental disintegration preceding rampant crime. In fact, environmental decay, drug use and crime continue to rise apparently in collaboration with each other. Additionally, the social service organizations are overwhelmed by the influx of immigrants, teenage pregnancy, and AIDS.

Sporting events have become first-order promotional tools of large cities, allowing them to reach levels of dissemination economically unaffordable as conventional advertising. The social impact of the event on residents is very important, given their role as main actors. Perceptions of the residents of the cities that host sporting events have been extensively studied, although in this case a singular point of comparison to study the perception of the costs of organizing and holding the sporting event is provided. The purpose of this chapter is to assess the perception of the citizens of Valencia (Spain) on specific aspects of three sports events held in the city in 2012: European Grand Prix Formula 1, the Tennis Open 500, and Valencia Marathon. The results show significant differences in the perception of the costs of organizing the events related, and demonstrate the impact of the type of activity in the perception of residents.

In São Paulo during the 1950s, a number of architectural projects for private residences had a significant impact on discussions concerning the relationship between architecture and the city within the context of industrial modernization and developmentism. The work of Vilanova Artigas (1915-1985) not only assembled the greatest number of theories on potential spatial and architectural configuration in this emerging peripheral metropolis but, from that moment onward, also had a permanent impact on Brazilian architecture. This was a period of expansive growth in the occupation and urbanization of Brazilian industrial cities and the problems thrown up by Vilanova Artigas’s architecture determined the endurance of architectural patterns which focused on a wide range of urbanity issues related to buildings which could not be controlled or changed by land occupations of that time. The aim of this work is to analyze the development of architectural and spatial patterns, which we believe, are at the root of the constructive experimentations in homes projected by Vilanova Artigas. Through his works, the architect was able to give shape to the social contradictions of the conservative modernization of South America’s greatest metropolis, São Paulo. The aim of this paper is to propose new topics which can assist the theorization of the difficult relationship between Brazilian architecture and the accelerated development of Brazil’s large cities. Brazil is currently undergoing a period of great urban transformations in the wake of the recent public and private investment in cities. Which local conceptions of architecture will counteract the processes of territorial degradation, a product of the aggression of economic movements driven by private conceptions of the collective space?

Based on the empirical analysis of contacts in the social network VKontakte, quantitative patterns are established that describe the distribution of users of social networks by the number of contacts (the number of friends). The parameter entering into the differential equation, whose solution is the proposed distribution, makes sense, similar to the Dunbar number and approximately coincides with it in magnitude. The fact that parameters characterizing a given distribution, depending on the size of the communication space in different cities, has been shown. However, the basic parameter that characterizes the fractal dimension of the communication space remains constant for all cities studied.

The concept of citizenship was introduced to the Arab and Islamic region duringthe colonial period. The law of citizenship, like all other laws and regulations inthe Middle East, was influenced by the colonial legacy that impacted the tribal and paternalistic systems in all aspects of life. In addition to the colonial legacy, most constitutions in the Middle East draw on the Islamic shari’a (law) as a major source of legislation, which in turn enhances the paternalistic system in the social sector in all its dimensions, as manifested in many individual laws and the legislative processes with respect to family status issues. Family is considered the nucleus of society in most Middle Eastern countries, and this is specifically reflected in the personal status codes. In the name of this legal principle, women’s submission is being entrenched, along with censorship over her body, control of her reproductive role, sexual life, and fertility.

The question of project manager competencies and especially in social projects is a key issue for social organizations seeking to progress and achieve success. If the manager has an important role to play with regard to the social organization, he’s however dependent on his behavioral, professional and personal capacities. The purpose of this paper is to show, on the basis of a quantitative study carried out among 120 managers of social projects in cooperatives located in the city of Agadir (Morocco), that the success of projects is conditioned by the leadership skills. Consequently, factors related to behavioral skills such as Solidarity; Involvement; Patience; Creativity; Empathy; Motivation; Trust; Commitment; Self-esteem; Transparency; Self-control; Discipline and other factors related to professional characteristics and personal characteristics of project managers prove a positive and significant relationship with the criterion of success studied.

This research deals with the development of  self concept of Hiroko as the main character in Namaku Hiroko by Nh. Dini and tries to identify how Hiroko is portrayed in the story, how she interacts with other characters and whether she is portrayed as a character dominated by ”I” element or  ”Me”  element seen  from sociological and cultural point of view. As a qualitative research in nature, the source of data in this research is the novel Namaku Hiroko (1967) and the data ara analyzed and presented deductively. The result of this analysis shows that in the novel, Hiroko as a fictional character is  portrayed as a girl whose personality  develops and changes drastically from ”Me”  to ”I”. When she was still in the village  l iving with her parents, she was portrayed as a obedient girl who was loyal to the parents, polite and acted in accordance with the social customs. In short, her personality was dominated by ”Me”  self concept. On the other hand, when she moved to the city (Kyoto), she was portrayed as a wild girl  no longer controlled by the social customs. She was  firm and determined totake decisions of  her won  for her future without considering what other people would say about her. She did not want to be treated as object. To put it in another way, her personality is more dominated by the ”I” self concept.
