The forms of power and the forms of cities: building on Charles Tilly

Chuck Tilly’s late work on coercion, capital, and trust is provocative when applied to changes in urban form. Extending those categories for use in tracing the history of conflicts in cities about how development should be handled highlights the changing roles of economic and physical and cultural power, and the growing importance of trust in these processes. This is a speculative article with a political hope. The speculation is around the potential of using an expanded version of key categories of Charles Tilly’s to create a framework for understanding the nature of change in the form of cities over time. The political hope is to use that framework to illuminate the possibilities of social change in cities today in the direction of social justice.

Mobility and accessibility in historic cities

The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local.     

Lean production of intensive cities: Using the power of Italo Calvino's imagination to grasp organizational change

This article analyses the introduction of Lean Production to ‘the Procurement Office’ (the Procurement Office is made anonymous due to promises of confidentiality in the research project ‘Lean without stress’), a work place marked by continuous organizational changes, unfavourable image and high turnover. This is analysed in terms of Italo Calvino's Invisible cities. It is argued that Calvino's themes and prose help us understand change as a multiplicity of temporal intensities producing ambivalence and affect. We describe this use of literary abstractions as a ‘hyperbolic social epistemology’. Through the depiction of four intensifications of Lean Production, the metaphors of Calvino's cities show how reality and illusion; hope and poverty; dreams and death and utopia and dystopia are intricately mingled and produce temporary and equally ambivalent affects of alienation, hypocrisy, self-governance, job-satisfaction, antagonisms and empowerment.

Living arrangements of elderly women and men in Chinese cities

Based on data from the 1988 Nine‐City Survey of the Elderly Aged 60 and Over, this study uses multivariate technique to examine how and to what extent demographic and socioeconomic characteristics of the elderly may motivate or discourage coresidence with married children. Focusing on seniors who have at least one married child, it contrasts two outcomes: living with married children and not living with married children. The analysis shows that being married and healthy significantly reduces coresidence with married children, whereas being financially dependent significantly increases the probability of coresidence. In addition, in contrast to the situations found in other Asian societies, gender is shown to have significant effect on coresidence, even after other variables are controlled.     

Measuring residential segregation in multi-ethnic and unequal European cities

Immigration flows and social inequalities reflect increased social and multi-ethnic segregation in contemporary urban Europe. For a better understanding of these processes, the present study investigates the main strengths of the multi-group residential indices, testing sensitivity and reliability under different metropolitan contexts in five European countries. These indices focus on different research dimensions and approach multi-group residential segregation conceptually and mathematically in a different way. A multivariate exploratory data analysis was adopted to classify the observed segregation patterns into a few homogeneous types and to delineate the multivariate relationship between the indices. The results of principal component analysis demonstrate that the indices assessing uniformity and disproportionality of the social groups analysed (H and D) contribute largely to the diversification in today's multi-ethnic communities, clarifying the importance of the dimension of evenness. Our results highlight how segregation is more evident in economically disadvantaged metropolitan regions with high levels of social vulnerability.
