Capital cities today remain central to both nations and states. They host centres of political power, not only national, but in some cases regional and global as well, thus offering major avenues to success, wealth and privilege. For these reasons capitals simultaneously become centres of 'counter-power', locations of high-stakes struggles between the government and the opposition. This volume focuses on capital cities in nine sub-Saharan African countries, and traces how the power vested in them has evolved through different colonial backgrounds, radically different kinds of regimes after independence, waves of popular protest, explosive population growth and in most cases stunted economic development. Starting at the point of national political emancipation, each case study explores the complicated processes of nation-state building through its manifestation in the 'urban geology' of the city – its architecture, iconography, layout and political use of urban space. Although the evolution of each of these cities is different, they share a critical demographic feature: an extraordinarily rapid process of urbanisation that is more politically than economically driven. Overwhelmed by the inevitable challenges resulting from this urban sprawl, the governments seated in most of these capital cities are in effect both powerful – wielding power over their populace – and powerless, lacking power to implement their plans and to provide for their inhabitants. In its concentration on urban forms of multi-layered power, symbolic as well as material, Capital Cities in Africa cuts a new path in the rich field of studies related to African cities and politics. It will be of interest to scholars in a wide range of disciplines, from political history, to sociology, to geography, architecture and urban planning.

Studies of government and politics in Africa are dominated by a focus on the national and are typically set apart by anglophone, francophone and lusophone historical influences, with South Africa as an exception. This volume departs from a different set of questions and employs a novel approach in discussing them: cities in sub-Saharan Africa provide the pivot around which issues of policy and practice, planning and service delivery turn, at different scales and both from the top down as well as from the bottom up. Party politics, for example, is discussed at city level and urban security both within a state and a non-state context. The novelty of the approach is found in thematic rather than single-city chapters written by multiple authors each of whom displays depth knowledge of one of three or more cities treated in each case. This volume will interest scholars of African and of urban studies as well as urban policy-makers and practitioners.

Case studies of metropolitan cities in nine African countries – from Egypt in the north to three in West and Central Africa, two in East Africa and three in Southern Africa – make up the empirical foundation of this publication.

The interrelated themes addressed in these chapters – the national influence on urban development, the popular dynamics that shape urban development and the global currents on urban development – make up its framework. All authors and editors are African, as is the publisher. The only exception is Göran Therborn whose recent book, Cities of Power, served as motivation for this volume. Accordingly, the issue common to all case studies is the often conflictual powers that are exercised by national, global and popular forces in the development of these African cities.

Rather than locating the case studies in an exclusively African historical context, the focus is on the trajectories of the postcolonial city (with the important exception of Addis Ababa with a non-colonial history that has granted it a special place in African consciousness). These trajectories enable comparisons with those of postcolonial cities on other continents. This, in turn, highlights the fact that Africa – today, the least urbanised continent on an increasingly urbanised globe – is in the thick of processes of large-scale urban transformation, illustrated in diverse ways by the case studies that make up the foundation of this publication.

In this work, the author reviews the current status of our knowledge about the cell cycle and the DNA damage response, followed by presenting his own scientific contributions to these fields. The reader is introduced to the complex issues of how cells divide and deal with damage to their DNA, in general and easy-to-read terms. In addition, a dedicated section of the book describes microscopy based tools to study these phenomena, such as the application of DNA damage in defined areas of the nucleus by laser microirradiation and studies of protein mobility by photobleaching techniques. This more technical part of the book is supplemented with a detailed outline of mathematical frameworks to analyze the ensuing data and deduct biological meaningful knowledge from them. The authors own papers, which are sequentially presented and discussed in broader terms, were published in high impact factor journals such as Nature Cell Biology, Molecular Cell and Journal of Cell Biology.

Identity has become the watchword of our times. In sub-Saharan Africa, this certainly appears to be true and for particular reasons. Africa is urbanising rapidly, cross-border migration streams are swelling and globalising influences sweep across the continent. Africa is also facing up to the challenge of nurturing emergent democracies in which citizens often feel torn between older traditional and newer national loyalties. Accordingly, collective identities are deeply coloured by recent urban as well as international experience and are squarely located within identity politics where reconciliation is required between state nation-building strategies and sub-national affiliations. They are also fundamentally shaped by the growing inequality and the poverty found on this continent. These themes are explored by an international set of scholars in two South African and two Francophone cities. The relative importance to urban residents of race, class and ethnicity but also of work, space and language are compared in these cities. This volume also includes a chapter investigating the emergence of a continental African identity. A recent report of the Office of the South African President claims that a strong national identity is emerging among its citizens, and that race and ethnicity are waning whilst a class identity is in the ascendance. The evidence and analyses within this volume serve to gauge the extent to which such claims ring true, in what everyone knows is a much more complex and shifting terrain of shared meanings than can ever be captured by such generalisations.
