Geographical Dimension

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.

ResumenLa extracción de la sal en la puntilla se ha venido desarrollando desde 1763, y ha sido un motor económico y medio para proveer de recursos a familias que artesanalmente se dedicaban a ella. Las salinas de la Provincia de Santa Elena conforman un ecosistema en el que convivencomunidades vegetales y especies endémicas y constituyen uno de los paisajes naturales más singulares de la provincia.En la actualidad el paisaje salinero se ha visto reducido en las últimas décadas por la expansión urbana y la carencia de políticas de estado que contemplen su conservación. El presente trabajo de investigación muestra el análisis de la situación de las salinas marinas, emplazadas en la costa de la ciudad de Salinas, centrándose en los cambios que han presentadoen los últimos años, debido a los procesos de urbanización. Desde una perspectiva histórica y etnográfica se describe el funcionamiento y  métodos de extracción de la sal; para la identificación y clasificación de las salinas tanto industriales como artesanales. El estudio comprende lavariación en la extensión de las salinas, y si son contempladas en las estrategias de protección frente al crecimiento urbano en los instrumentos normativos municipales.AbstractSalt extraction in The Salinas has been developing since 1763 and has been an economic and an engine to provide resources to families who were handcrafted engaged in it. The Salina’s municipality make up an ecosystem in which plant communities and endemic species coexist andconstitute one of the most unique provinces’s natural landscapes.Today the salt landscape has been reduced in recent decades by urban expansion and the lack of State Policies that contemplate its conservation. This research paper shows the analysis of the the salt marshes’s situation, located on the coast of the city of Salinas, focusing on the changes theyhave presented in recent years, due to urbanization processes. From a historical and ethnographic perspective, the operation and methods of salt extraction are described, for the identification and classification of both industrial and handcrafted salt flats. The study comprises the variation in the extension of the Salinas, and if they are contemplated in the strategies of protection against the urban growth in the normative instruments of the municipality.Salinas as a city its contemplating the implementation of strategies for protection of these ecosystems against the urban growth in the normative instruments of the municipality.

Considering the fact that the pavement condition of municipal roads has considerable influence on urban mobility, appropriate management of this structure is necessary and requires a significant amount of financial resources and labour. The visualization of the pavement condition on thematic maps can optimize decision making and resource allocation. Thus, this work has as its main objective to elaborate thematic maps of the pavement condition and to evaluate the utility of these representations for allocation of investments intended to the maintenance of these structures. For that, thematic maps were created in QuantumGIS (QGIS) software, using the Value of the Surface Condition (VCS) of some sections evaluated in the city of Ribeirão Preto/SP. The results indicate that the visualization of this information through thematic representations, created in Geographic Information Systems (GIS), allow the pavement management to become more efficient, optimizing resource allocation and economizing in pavement valuation services.

This chapter defines the smart city in terms of the process whereby computers and computation are being embedded into the very fabric of the city itself. In short, the smart city is the automated city where the goal is to improve the efficiency of how the city functions. These new technologies tend to improve the performance of cities in the short term with respect to how cities function over minutes, hours or days rather than over years or decades. After establishing definitions and context, the author then explores questions of big data. One important challenge is to synthesize or integrate different data about the city's functioning and this provides an enormous challenge which presents many obstacles to producing coherent solutions to diverse urban problems. The chapter augments this argument with ideas about how the emergence of widespread computation provides a new interface to the public realm through which citizens might participate in rather fuller and richer ways than hitherto, through interactions in various kinds of decision-making about the future city. The author concludes with some speculations as to how the emerging science of smart cities fits into the wider science of cities.

The theme urban mobility has been gaining prominence in recent times due to the impact it causes on the quality of life of people living in large centers, this article aims to study and evaluate the Capacity and Level of Service in a specific route in the city of São Paulo based on the concepts and methods established in Highway Capacity Manual 2000 (HCM 2000), in addition to using linear regression to estimate the forecast of short-term traffic demand in a biennial scenario, to propose alternatives to provide a satisfactory Service Level compatible with the forecast demand, to analyze the efficiency of the method as a tool in the decision-making process in the measures for the improvement of circulation and retardation in the municipal road system. In this exploratory, quantitative and descriptive study, the calculations were performed using concepts and methods contained in HCM 2000 evaluating the efficiency of the method as a means of obtaining information to support decision-making regarding the improvement of urban mobility. The results showed a tendency to reduce the volume of vehicle flow in the studied road. The results obtained demonstrate that the tools applied in the present work can be of great value for decision making or proposition measures for improvements in the attendance of demand in the capacity of the roads to provide a Service Level that allows to improve the satisfaction of the users of the road system of the municipality of São Paulo.

The study of patterns of urban mobility is of utter importance for city growth projection and development planning. In this paper, we analyze the topological aspects of the street network of the coastal city of Cartagena de Indias employing graph theory and spatial syntax tools. We find that the resulting network can be understood on the basis of 400 years of the city’s history and its peripheral location that strongly influenced and shaped the growth of the city, and that the statistical properties of the network resemble those of self-organized cities. Moreover, we study the mobility through the network using a simple agent-based model that allows us to study the level of street congestion depending on the agents’ knowledge of the traffic while they travel through the network. We found that a purely shortest-path travel scheme is not an optimal strategy and that assigning small weights to traffic avoidance schemes increases the overall performance of the agents in terms of arrival success, occupancy of the streets, and traffic accumulation. Finally, we argue that localized congestion can be only partially ascribed to topological properties of the network and that it is important to consider the decision-making capability of the agents while moving through the network to explain the emergence of traffic congestion in the system.

Background. The transition from student to new graduate occupational therapist is recognized as stressful. Current literature has not specifically drawn together the challenges new graduates face when learning to work with clients. Purpose. This review aimed to synthesize common challenges that new graduate occupational therapists face when working with clients. Methods. Searches of online scholarly databases located research articles. Content related to working with clients in practice was charted using the Matrix Method. Findings. From 21 articles, four categories of challenges were identified: “reasoning and decision-making,” “using knowledge and skills in practice with clients,” “the context of service provision,” and “managing caseload and priorities.” “Having self-doubt” was a theme that pervaded the data. Implications. New graduates often do not feel fully prepared for all aspects of occupational therapy practice. As they may not have access to substantial workplace support, exploring personal resources and professional support may assist this challenging transition.

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.
