Emotional interactions and an ethic of care: caring relations in families affected by HIV and AIDS

In the context of global processes of economic restructuring, the HIV and AIDS epidemic and socio-cultural constructions of care, many women and young people in low-income households have been drawn into caring roles within the family. Drawing on the literature on an ethics of care, emotional geographies and embodiment, this paper examines the emotional dynamics of the caring process in families affected by HIV and AIDS. Based on the perspectives of both ‘caregivers’ and ‘care-receivers’ from research undertaken in Namibia, Tanzania and the UK, we examine the everyday practices of care that women and young people are engaged in and explore how emotions are performed and managed in caring relationships. Our research suggests caregivers play a crucial role in providing emotional support and reassurance to people with HIV, which in turn often affects caregivers' emotional and physical wellbeing. Within environments where emotional expression is restricted and HIV is heavily stigmatised, caregivers and care-receivers seek to regulate their emotions in order to protect family members from the emotional impacts of a chronic, life-limiting illness. However, whilst caregiving and receiving may lead to close emotional connections and a high level of responsiveness, the intensity of intimate caring relationships, isolation and lack of access to adequate resources can cause tensions and contradictory feelings that may be difficult to manage. These conflicts can severely constrain carers' ability to provide the ‘good care’ that integrates the key ethical phases in Tronto's (1993) ideal of the caring process.

Poverty, migration and sex work: youth transitions in Ethiopia

Despite an emerging body of work on youth transitions, research has yet to explore the often unconventional routes to adulthood for young people marginalised through poverty. By drawing on interviews with 60 young commercial sex workers in Ethiopia, this paper explores the connections between poverty, migration and sex work and demonstrates that sex work provides a risky alternative, but often successful, path to independence for some rural-urban migrants. The paper concludes by offering recommendations for policies that seek to support young sex workers by enabling them to maintain their independence while seeking different employment.

Access to historic environments for tourists with disabilities: a compromise?

Historic environments, the basis for heritage tourism, are difficult to access for people with disabilities. Many countries have introduced legislation to promote equal rights for people with disabilities. Historic environments, however, enjoy protection under national planning systems which limit the physical access improvements that can be made. The significance of historic environments for tourism in the UK is outlined. Barriers restricting tourists with disabilities accessing historic sites are reviewed from the heritage tourism service provider's viewpoint. Interests of the major stakeholders are considered in terms of the apparent conflict between conservation and access issues as heritage tourism service providers seek to comply with disability discrimination legislation. From a study of access improvements made by major heritage tourism service providers, good practice is identified. However, physical access improvements to enable tourists with disabilities to visit historic environments are a compromise because of the strength of conservation interests. Questions remain as to whether this compromise is acceptable to the tourist with disabilities and whether intellectual access is an acceptable substitute for physical presence.

Remaking place and securitising space: Urban regeneration and the strategies, tactics and practices of policing in the UK

Urban regeneration programmes in the UK over the past 20 years have increasingly focused on attracting investors, middle-class shoppers and visitors by transforming places and creating new consumption spaces. Ensuring that places are safe and are seen to be safe has taken on greater salience as these flows of income are easily disrupted by changing perceptions of fear and the threat of crime. At the same time, new technologies and policing strategies and tactics have been adopted in a number of regeneration areas which seek to establish control over these new urban spaces. Policing space is increasingly about controlling human actions through design, surveillance technologies and codes of conduct and enforcement. Regeneration agencies and the police now work in partnerships to develop their strategies. At its most extreme, this can lead to the creation of zero-tolerance, or what Smith terms 'revanchist', measures aimed at particular social groups in an effort to sanitise space in the interests of capital accumulation. This paper, drawing on an examination of regeneration practices and processes in one of the UK's fastest-growing urban areas, Reading in Berkshire, assesses policing strategies and tactics in the wake of a major regeneration programme. It documents and discusses the discourses of regeneration that have developed in the town and the ways in which new urban spaces have been secured. It argues that, whilst security concerns have become embedded in institutional discourses and practices, the implementation of security measures has been mediated, in part, by the local socio-political relations in and through which they have been developed.

Governmentality, subject-building, and the discourses and practices of devolution in the UK

This paper uses a Foucauldian governmentality framework to analyse and interrogate the discourses and strategies adopted by the state and sections of the business community in their attempts to shape and influence emerging agendas of governance in post-devolution Scotland. Much of the work on governmentality has examined the ways in which governments have developed particular techniques, rationales and mechanisms to enable the functioning of governance programmes. This paper expands upon such analyses by also looking at the ways in which particular interests may use similar procedures, discourses and practices to promote their own agendas and develop new forms of resistance, contestation and challenge to emerging policy frameworks. Using the example of business interest mobilization in post-devolution Scotland, it is argued that governments may seek to mobilize defined forms of expertise and knowledge, linking them to wider political debates. This, however, creates new opportunities for interests to shape and contest the discourses and practices of government. The governmentalization of politics can, therefore, be seen as more of a dialectical process of definition and contestation than is often apparent in existing Foucault-inspired writing.

Construction contracts: law and management (3rd edition)

This book is aimed primarily at students for whom the study of building or civil engineering contracts forms part of a construction-based course. We have had in mind the syllabus requirements for first degrees in Building, Civil Engineering, Architecture, Quantity Surveying and Building Surveying, as well as those of postgraduate courses in Construction Management and Project Management. We have also assumed that such students will already have been introduced to the general principles of English law, especially those relating to contract and tort. As a result, while aspects of those subjects that are of particular relevance to construction are dealt with here, the reader must look elsewhere for the general legal background. In producing this third edition, we have again been greatly assisted by the many helpful comments made by reviewers and users of its predecessor. Nonetheless, our basic aim is identical to that which underpinned the first edition: to provide an explanation of the fundamental principles of construction contract law, rather than a clause-by-clause analysis of any particular standard-form contract. As a result, while we draw most frequently upon JCT 98 for our illustrations of particular points, this merely reflects the pre-eminent position occupied by that particular form of contract in the UK construction industry. We conclude by repeating our previous warning as to the dangers inherent in a little learning. Neither this book, nor the courses for which it is intended, seek to produce construction lawyers. The objective is rather to enable those who are not lawyers to resolve simple construction disputes before they become litigious, and to recognize when matters require professional legal advice. It should be the aim of every construction student to understand the legal framework sufficiently that they can instruct and brief specialist lawyers, and this book is designed to help them towards that understanding.

Construction contract policy: do we mean what we say?

Recent developments in contracting practice in the UK have built upon recommendations contained in highprofile reports, such as those by Latham and Egan. However, the New Engineering Contract (NEC), endorsed by Latham, is based upon principles of contract drafting that seem open to question. Any contract operates in the context of its legislative environment and current working practices. This report identifies eight contentious hypotheses in the literature on construction contracts and tests their validity in a sample survey that attracted 190 responses. The survey shows, among other things, that while partnership is a positive and useful idea, authoritative contract management is considered more effective and that “win-win” contracts, while desirable, are basically impractical. Further, precision and fairness in contracts are not easy to achieve simultaneously. While participants should know what is in their contracts, they should not routinely resort to legal action; and standard-form contracts should not seek to be universally applicable. Fundamental changes to drafting policy should be undertaken within the context of current legal contract doctrine and with a sensitivity to the way that contracts are used in contemporary practice. Attitudes to construction contracting may seem to be changing on the surface, but detailed analysis of what lies behind apparent agreement on new ways of working reveals that attitudes are changing much more slowly than they appear to be.

Feminist geography, prehistory of

The article traces the beginnings and early history of feminist geography in the United Kingdom through the memories and personal narratives of two women who were heavily involved in this field of geographical research, in the 1970s, and were founder members of the Women and Geography Study Group of the Institute of British Geographers. The article begins by considering the context (both political and academic) within which feminist geography was born. Second-wave feminism and the rise of the women’s movement, initially in the United States, is seen as a major influence on the development of feminist geography. In the academic world, it was the dominance of quantitative geography in the 1960s, and the related opposition to this positivist paradigm by humanistic and socialist geographers, which led to calls for a recognition of the inequalities faced by women in society and an understanding of the differences in men’s and women’s lives. Through personal narratives, the authors seek to illustrate the obstacles and disagreements, as well as the encouragements and opportunities, which led to the birth of UK-feminist geography. Many individual geographers, influential to the story, are referred to, seen through the eyes of the authors at that time.

‘We are managing our own lives...’: life transitions and care in sibling-headed households affected by AIDS in Tanzania and Uganda

This paper explores the ways that young people express their agency and negotiate complex lifecourse transitions according to gender, age and inter- and intra-generational norms in sibling-headed households affected by AIDS in East Africa. Based on findings from a qualitative and participatory pilot study in Tanzania and Uganda, I examine young people's socio-spatial and temporal experiences of heading the household and caring for their siblings following their parent's/relative's death. Key dimensions of young people's caring pathways and life transitions are discussed: transitions into sibling care; the ways young people manage changing roles within the family; and the ways that young people are positioned and seek to position themselves within the community. The research reveals the relational and embodied nature of young people's life transitions over time and space. By living together independently, young people constantly reproduce and reconfigure gendered, inter- and intra-generational norms of ‘the family’, transgressing the boundaries of ‘childhood’, ‘youth’ and ‘adulthood’. Although young people take on ‘adult’ responsibilities and demonstrate their competencies in ‘managing their own lives’, this does not necessarily translate into more equal power relations with adults in the community. The research reveals the marginal ‘in-between’ place that young people occupy between local and global discourses of ‘childhood’ and ‘youth’ that construct them as ‘deviant’. Although young people adopt a range of strategies to resist marginalisation and harassment, I argue that constraints of poverty, unequal gender and generational power relations and the emotional impacts of sibling care, stigmatisation and exclusion can undermine their ability to exert agency and control over their sexual relationships, schooling, livelihood strategies and future lifecourse transitions.

Young caregiving and HIV in the UK: caring relationships and mobilities in African migrant families

Recent research in Sub-Saharan Africa has revealed the importance of children’s caring roles in families affected by HIV and AIDS. However, few studies have explored young caregiving in the context of HIV in the UK, where recently arrived African migrant and refugee families are adversely affected by the global epidemic. This paper explores young people’s socio-spatial experiences of caring for a parent with HIV, based on qualitative research with 37 respondents in London and other urban areas in England. In-depth semi-structured interviews were conducted with young people with caring responsibilities and mothers with HIV, who were predominantly African migrants, as well as with service providers. Drawing on their perspectives, the paper discusses the ways that young people and mothers negotiate the boundaries of young people’s care work within and beyond homespace, according to norms of age, gender, generational relations and cultural constructions of childhood. Despite close attachments within the family, the emotional effects of living with a highly stigmatised life-limiting illness, pressures associated with insecure immigration status, transnational migration and low income undermined African mothers’ and young people’s sense of security and belonging to homespace. These factors also restricted their mobility and social participation in school/college and neighbourhood spaces. While young people and mothers valued supportive safe spaces within the community, the stigma surrounding HIV significantly affected their ability to seek support. The article identifies security, privacy, independence and social mobility as key dimensions of African young people’s and mothers’ imagined futures of ‘home’ and ‘family’.

Budding Aphrodite: into the future

As with many aspects of antiquity, the more we discover about Aphrodite, the more we seek. Images of her or others in her guise are extensive; work over the last two hundred years provides important historical and archaeological contexts that connect the images with their creators and users. These contexts are now an important means of understanding Aphrodite’s divine personality or role(s) in various places and times. Although ancient attestation for her is sometimes less than for other goddesses, there is certainlymore post-antique evidence for her Nachleben— as herself, as Venus, or as an archetype or stereotype. Our comprehension is nonetheless complicated by the variety of ways she is perceived and received—in cult, art, and literature—up to the present.

Data assimilation for marine monitoring and prediction: The MERCATOR operational assimilation systems and the MERSEA developments

During the past 15 years, a number of initiatives have been undertaken at national level to develop ocean forecasting systems operating at regional and/or global scales. The co-ordination between these efforts has been organized internationally through the Global Ocean Data Assimilation Experiment (GODAE). The French MERCATOR project is one of the leading participants in GODAE. The MERCATOR systems routinely assimilate a variety of observations such as multi-satellite altimeter data, sea-surface temperature and in situ temperature and salinity profiles, focusing on high-resolution scales of the ocean dynamics. The assimilation strategy in MERCATOR is based on a hierarchy of methods of increasing sophistication including optimal interpolation, Kalman filtering and variational methods, which are progressively deployed through the Syst`eme d’Assimilation MERCATOR (SAM) series. SAM-1 is based on a reduced-order optimal interpolation which can be operated using ‘altimetry-only’ or ‘multi-data’ set-ups; it relies on the concept of separability, assuming that the correlations can be separated into a product of horizontal and vertical contributions. The second release, SAM-2, is being developed to include new features from the singular evolutive extended Kalman (SEEK) filter, such as three-dimensional, multivariate error modes and adaptivity schemes. The third one, SAM-3, considers variational methods such as the incremental four-dimensional variational algorithm. Most operational forecasting systems evaluated during GODAE are based on least-squares statistical estimation assuming Gaussian errors. In the framework of the EU MERSEA (Marine EnviRonment and Security for the European Area) project, research is being conducted to prepare the next-generation operational ocean monitoring and forecasting systems. The research effort will explore nonlinear assimilation formulations to overcome limitations of the current systems. This paper provides an overview of the developments conducted in MERSEA with the SEEK filter, the Ensemble Kalman filter and the sequential importance re-sampling filter.

Conservative upwind difference schemes for the Euler equations for real gas flows in a duct

In a recent paper [P. Glaister, Conservative upwind difference schemes for compressible flows in a Duct, Comput. Math. Appl. 56 (2008) 1787–1796] numerical schemes based on a conservative linearisation are presented for the Euler equations governing compressible flows of an ideal gas in a duct of variable cross-section, and in [P. Glaister, Conservative upwind difference schemes for compressible flows of a real gas, Comput. Math. Appl. 48 (2004) 469–480] schemes based on this philosophy are presented for real gas flows with slab symmetry. In this paper we seek to extend these ideas to encompass compressible flows of real gases in a duct. This will incorporate the handling of additional terms arising out of the variable geometry and the non-ideal nature of the gas.

Risk and price in the bidding process of contractors

Formal and analytical risk models prescribe how risk should be incorporated in construction bids. However, the actual process of how contractors and their clients negotiate and agree on price is complex, and not clearly articulated in the literature. Using participant observation, the entire tender process was shadowed in two leading UK construction firms. This was compared to propositions in analytical models and significant differences were found. 670 hours of work observed in both firms revealed three stages of the bidding process. Bidding activities were categorized and their extent estimated as deskwork (32%), calculations (19%), meetings (14%), documents (13%), off-days (11%), conversations (7%), correspondence (3%) and travel (1%). Risk allowances of 1-2% were priced in some bids and three tiers of risk apportionment in bids were identified. However, priced risks may sometimes be excluded from the final bidding price to enhance competitiveness. Thus, although risk apportionment affects a contractor’s pricing strategy, other complex, microeconomic factors also affect price. Instead of pricing in contingencies, risk was priced mostly through contractual rather than price mechanisms, to reflect commercial imperatives. The findings explain why some assumptions underpinning analytical models may not be sustainable in practice and why what actually happens in practice is important for those who seek to model the pricing of construction bids.
