Urban population growth requires an appropriate and suitable place for future population to cope with the expected urban expansion of major cities in developing countries, and to identify an indicator urban expansion to guide planners, architects and decision makers, and help them reduce negative effects of city expansion with improvement in the ability to live in cities.  The density (population and building), fragmentation (saturation and openness) and compactness (proximity and cohesion) are the most important indicators of urban expansion of cities, which gives a clear perception of how city expands and possibility of adopting the most suitable ones when updating or preparing master lans. Most cities, especially Arab ones, suffer from excessive urban expansion, resulting in various urban problems affecting quality of life, services and city performance, which is the problem of research. This research is aimed at identifying factors influencing urban expansion of cities in developing countries when preparing for their future expansion, by analyzing the indicators of urban expansion of a set of cities to reach appropriate indicators for urban expansion sustainable future of the city to ensure orderly development of cities and make them more productive, more comprehensive and sustainable in upcoming decades.

The geographical dimension of urbanization is of major importance in depicting the influences of urbanization on the development of a city, since complex social-ecological systems interact in a multitude of ways at many spatial scales across time. This research introduced an indicator for assessing the spatial sustainability of a city from the perspective of landscape ecology, to provide a reasonable way for quantifying the spatial dynamic of the urban area of a city and how close the pattern of urban expansion close to a ‘compact’ way. A case study has been done in Xi’an. With the application of remote sensing technology, landscape ecology and other necessary software, the spacial sustainability of Xi’an from 1988 to 2010 were calculated, the rapid urbanization in Xi’an has significantly promoted the spatial sustainability of city from 1988 to 2000 and 2006 to 2010, whereas exerted negative effects on the spatial sustainability of the city from 2000 to 2006.

Purpose Corruption affects development and quality of life of citizens in affected countries. The increase in anti-corruption measures globally reflects a consensus that corruption is pervasive and costly. Public procurement is one area in which corruption manifests because of the sums of money involved; the asymmetry of information; and the bureaucratic nature of decision-making, which presents opportunities for abuse. In developing countries, procurement corruption is rife because of institutional weaknesses, lack of enforced accountability mechanisms and culture of silence in relation to public sector malfeasance. Design/methodology/approach This paper examines procurement corruption in countries with systemic corruption, using Nigeria as a case study, to determine how to reduce public procurement corruption. Findings The paper will highlight prevalent corrupt schemes in public procurement in Nigeria, examine the reasons for the failure of state anti-corruption institutions and analyze the kinds of initiatives that reduced procurement corruption and increased accountability in other countries and the utility of adopting such mechanisms in the Nigerian context.

Using heritage as a cultural artifact in city development is not new, but little has been explored about how urban heritage can be utilized as new generative value and a new planning instrument for the revival of cities. The purpose of this paper is to show the creative and the generative use of urban heritage, both for the extension of cultural and tourist offer of the city and for the improvement of the quality of life in physical, social and economic terms for the community. The case study method was used for the adaptive reuse of projects for heritage buildings and urban revival in Kikinda. We argue that urban heritage has to be used, bearing in mind its spatial, economic and social sustainability aspects, and become a generator of urban revival. We go beyond recognition of the value of heritage as a cultural artifact that should solely be preserved and used as a static element in urban development, and view it more as a dynamic asset for city revival processes. We found that for the heritage nodes to be utilized as the new generative value for the revival of cities, they have to be perceived from the network perspective, thus influencing the urban environment in a sustainable way.

ABSTRACT Favelas are low-income urban communities in Brazil, and Maré in Rio de Janeiro has the largest cluster of favelas in the country. The prevailing view of a unique, regulated, and normative city conflicts with the reality of the continued expansion of the favelas, posing challenges for architects and urban planners in developing new strategies for integrating informal areas with the main city. This study focused on a decaying industrial area adjacent to the Maré favelas and explored a sustainable path for improving both the quality of the built environment and the quality of life of the residents. Effective infrastructure and socioeconomic links between the favelas and the city were proposed. The home production model that emerged from the favelas inspired the use of the abandoned industrial area as a home-industry incubator. The study proposed an urban regeneration strategy involving a bottom-up industry-space process evolving from home industries to group industries, and finally to larger community industries. This strategy can accelerate Maré’s development and integration with the city of Rio de Janeiro.

This chapter focuses on the objectives, issues and influencing factors of national ICT policies in developing countries. It points out how policy has become the driving force for ICT growth; how it can empower a nation and transform its social and economic life thereby improving on the quality of life of its citizens. It further discusses the objectives and issues of ICT policy. It later examines the factors that affect ICT policy Examples of some developing countries in Africa and Asia with national ICT policies were also given. The chapter concludes that unless a strong national policy institution with dedicated policy decision makers charged with the responsibility of monitoring ICT policy implementation are in place, ICT policies will not be effective in developing countries.

This article aims to discuss the determinants of digital active citizenship behaviors such as the e-participation using reporting urban apps. The article makes a comparative analysis between two groups of citizens: a) 98 users of a reporting app (MyHomeCity) who were selected for the case study); and b) 148 non-users of reporting apps. Users of MyHomeCity revealed higher scores for the satisfaction for life in the city, self-esteem, self-efficacy, and perceived happiness, for all place attachment dimensions and all digital citizenship dimensions except for political activism (online and offline) and critical perspective. The probability of being an app user is predicted by satisfaction for living in the city, place identity (attachment), and digital citizenship dimensions. The implications for public decision makers, app developers, and citizens' organizations are discussed.

The aim of this study was to analyze the level of satisfaction in three municipal sports centers in the city of Malaga and to learn and analyze the characteristics of users older than 40 years of age in these centers. A total of 303 persons (123 men and 180 women) from three sports centers in the city of Malaga participated in this study (M = 58.14, SD = 7.16 years). The Evaluation of Perceived Quality in Sports Services test (CECASDEP) was used, and the results demonstrated that the different dimensions studied—sports center, activity space, locker rooms, program of activities, and trainer—were very positively correlated. The level of customer loyalty increased with user satisfaction and perceived quality of services as well as the age of the person. Users were also found to be more motivated to take part in physical activities due to greater satisfaction. The highest scores were given to the trainers, who played a key role in all three sports centers. In conclusion, we gathered important insights into perceived quality in different sports centers. This information can be used by sports managers to strengthen dimensions with lower scores and improve those with higher scores. In addition, the study confirms that the level of customer loyalty is related to the perceived quality scores. Therefore, the use of measuring instruments is recommended to optimize the quality of sports services.
