The hawari of Cairo - narrow non-straight alleyways - are the basic urban units that have formed the medieval city since its foundation back in 969 AD. Until early in the C20th, they made up the primary urban divisions of the city and were residential in nature. Contemporary hawari, by contrast, are increasingly dominated by commercial and industrial activity. This medieval urban maze of extremely short, broken, zigzag streets and dead ends are defensible territories, powerful institutions, and important social systems. While the hawari have been studied as an exemplar for urban structure of medieval Islamic urbanism, and as individual building typologies, this book is the first to examine in detail the socio-spatial practice of the architecture of home in the city. It investigates how people live, communicate and relate to each other within their houses or shared spaces of the alleys, and in doing so, to uncover several new socio-spatial dimensions and meanings in this architectural form.
In an attempt to re-establish the link between architecture past and present, and to understand the changing social needs of communities, this book uncovers the notion of home as central to understand architecture in such a city with long history as Cairo. It firstly describes the historical development of the domestic spaces (indoor and outdoor), and provides an inclusive analysis of spaces of everyday activities in the hawari of old Cairo. It then broadens its analysis to other parts of the city, highlighting different customs and representations of home in the city at large. Cairo, in the context of this book, is represented as the most sophisticated urban centre in the Middle East with different and sometimes contrasting approaches to the architecture of home, as a practice and spatial system.
In order to analyse the complexity and interconnectedness of the components and elements of the hawari as a 'collective home', it layers its narratives of architectural and social developments as a domestic environment over the past two hundred years, and in doing so, explores the in-depth social meaning and performance of spaces, both private and public.

Abstract In theory, improvements in healthy life expectancy should generate increases in the average age of retirement, with little effect on savings rates. In many countries, however, retirement incentives in social security programs prevent retirement ages from keeping pace with changes in life expectancy, leading to an increased need for life-cycle savings. Analyzing a cross-country panel of macroeconomic data, we find that increased longevity raises aggregate savings rates in countries with universal pension coverage and retirement incentives, though the effect disappears in countries with pay-as-you-go systems and high replacement rates.

Purpose
– Information science has been conceptualized as a partly unreflexive response to developments in information and computer technology, and, most powerfully, as part of the gestalt of the computer. The computer was viewed as an historical accident in the original formulation of the gestalt. An alternative, and timely, approach to understanding, and then dissolving, the gestalt would be to address the motivating technology directly, fully recognizing it as a radical human construction. This paper aims to address the issues.
Design/methodology/approach
– The paper adopts a social epistemological perspective and is concerned with collective, rather than primarily individual, ways of knowing.
Findings
– Information technology tends to be received as objectively given, autonomously developing, and causing but not itself caused, by the language of discussions in information science. It has also been characterized as artificial, in the sense of unnatural, and sometimes as threatening. Attitudes to technology are implied, rather than explicit, and can appear weak when articulated, corresponding to collective repression.
Research limitations/implications
– Receiving technology as objectively given has an analogy with the Platonist view of mathematical propositions as discovered, in its exclusion of human activity, opening up the possibility of a comparable critique which insists on human agency.
Originality/value
– Apprehensions of information technology have been raised to consciousness, exposing their limitations.

Social immune systems comprise immune defences mounted by individuals for the benefit of others (sensu Cotter & Kilner 2010a). Just as with other forms of immunity, mounting a social immune response is expected to be costly but so far these fitness costs are unknown. We measured the costs of social immunity in a sub-social burying beetle, a species in which two or more adults defend a carrion breeding resource for their young by smearing the flesh with antibacterial anal exudates. Our experiments on widowed females reveal that a bacterial challenge to the breeding resource upregulates the antibacterial activity of a female's exudates, and this subsequently reduces her lifetime reproductive success. We suggest that the costliness of social immunity is a source of evolutionary conflict between breeding adults on a carcass, and that the phoretic communities that the beetles transport between carrion may assist the beetle by offsetting these costs.

Neotropical orchid bees (Euglossini) are conspicuously different from other corbiculate bees (Apinae) in their lack of advanced sociality and in male use of acquired odors (fragrances) as pheromone-analogues. In both contexts, orchid bee mating systems, in particular the number of males a female mates with, are of great interest but are currently unknown. To assess female mating frequency in the genus Euglossa, we obtained nests from three species in Mexico and Panama and genotyped mothers and their brood at microsatellite DNA loci. In 26 out of 29 nests, genotypes of female brood were fully consistent with being descended from a singly mated mother. In nests with more than one adult female present, those adult females were frequently related, with genotypes being consistent with full sister-sister (r = 0.75) or mother-daughter (r = 0.5) relationships. Thus, our genetic data support the notions of female philopatry and nest-reuse in the genus Euglossa. Theoretically, single mating should promote the evolution of eusociality by maximizing the relatedness among individuals in a nest. However, in Euglossini this genetic incentive has not led to the formation of eusocial colonies as in other corbiculate bees, presumably due to differing ecological or physiological selective regimes. Finally, monandry in orchid bees is in agreement with the theory that females select a single best mate based on the male fragrance phenotype, which may contain information on male age, cognitive ability, and competitive strength.

This paper analyses the interaction between neoliberal inspired reforms of public services and the mechanisms for achieving public accountability. Where once accountability was exercised through the ballot box, now in the neoliberal age managerial and market based forms of accountability predominate. The analysis identifies resistance from civil society campaigns to the neoliberal restructuring of public services which leads to public accountability (PA) becoming a contested arena. To develop this analysis a re-theorisation of PA, as a relationship where civil society seeks to control the state, is explored in the context of social housing in England over the past thirty years. Central to this analysis is a dialogical analysis of key documents from a social housing regulator and civil society campaign. The analysis shows that the current PA practices are an outcome of both reforms from the government and resistance from civil society (in the shape of tenants’ campaigns). The outcome of which is to tell the story of the changes in PA (and accountability) centring on an analysis of discourse. Thus, the paper moves towards answering the question – what has happened to PA during the neoliberal age?

Participatory citizenship education has been highlighted as a strategy to promote social cohesion in divided societies whereby collaborations with Non-Governmental Organisations and inter-school links have been proposed as tools to improve social networks between schools and communities. This article explores the role and meaning of citizenship education and cross-community participation in promoting social capital and social cohesion. School survey findings, focus groups and interviews with young people and educators indicated that differences between school sectors and established allegiances with particular communities and NGOs may limit the potential for citizenship education to produce bridging social capital and serve to reproduce bonding social capital. It is argued that the introduction of citizenship curricula into segregated schools systems in divided societies may be useful to promote citizenship values and positive attitudes to the other but insufficient to promote the development of bridging social capital and, ultimately, social cohesion in the long term.

New understandings arise as we encounter the emergent integration of both rational and emotional, physical and spiritual, masculine and feminine through imagination, myth, and storytelling. This expanded space fosters an iterative spiraling process whereby new personal and collective futures emerge from transformative possibilities. Contemplating love and the situatedness of our being creates a space for seeing differently, more inclusively. Thought Woman tells a story of encounters arising from contemplation, framing an emancipatory path toward wholeness and unity, being shaped through becoming, recognizing the interrelated web of life wherein humankind can flourish. Flourishing represents the central focus of the critical accounting project.
