A simulation of the transmission of HIV and AIDS in regional populations within the United Kingdom

"The spread of HIV-1 in the United Kingdom is simulated by a model which integrates behavioural and epidemiological processes within a multi-regional population projection framework and represents the spatial heterogeneities in the distribution of HIV which have significant effects on transmission patterns. Analyses determine the significance of different parameters in contributing to prediction uncertainty and highlight the importance of behavioural change and international population movements."     

Why Scotland needs more than just a new migration policy

The Scottish Executive has adopted a policy to combat Scotland's declining population by encouraging inward migration. Using a multi‐state population model this paper presents nine long‐term population scenarios for Scotland using three net international migration levels and three fertility paths. The results show inward migration can slow population decline but makes little difference to population ageing. Without a higher fertility rate Scotland's population will become demographically unsustainable. Our simulations show that a higher fertility rate substantially reduces the future ageing.     

THE INDUSTRIAL RESTRUCTURING OF SOUTH WALES: THE CAREER OF A STATE MANAGED REGION

This paper examines the causes of the current economic crisis in the industrial region of South Wales. The authors maintain that past as well as current government policies have played a major role in bringing about the crisis by contributing to the vulnerability of communities in South Wales. The authors review the history of the policies which have contributed to the current steel and coal crises. They then provide a brief discussion of current legislative policies designed to combat the crises. Finally, they critique alternative strategies: continued monetarism; a return To Keynesian/‘corporatist’ policies; and the radical restructuring demanded by an ‘Alternative Economic Strategy’ (AES).     

A REPLY TO J.A. SYBESMA IRONSIDE

S ilence is the correct response to an unflattering critical commentary that does not misrepresent one's views. But for a commentary that seems to have sprung from a complete misreading of the text, one can only reply loudly and at length. I will deal with the criticisms levelled by Professor Ironside in order of occurrence.     

Nineteenth-century planned industrial communities and the role of aesthetics in spatial practices: the visual ideologies of Pullman and Port Sunlight

In the 1880s British and American planned industrial communities revealed a distinct shift in spatial practices as two discrete architecture and landscape architectural aesthetics were applied to community design: Beaux Arts, and Arts and Crafts. Two of the most extensive planned industrial communities during this decade received aesthetic attention: Pullman, Illinois near Chicago (1880), established by George Pullman, and Port Sunlight, near Liverpool (1888), established by William Lever. Both Pullman and Lever believed that by applying a distinctive aesthetic they could establish a cohesive visual ideology for social control. Lever and Pullman believed that by creating “beautiful” spaces, this would encourage and/or constrain worker attitudes and behaviors, what Henri Lefebvre calls “means of control” (1991, p 26). In addition, both Pullman and Port Sunlight became central to establishing and maintaining each company's brand identity. This paper explores the visual ideologies these two industrialists used to produce a distinctive sense of community while also revealing the inherent tensions and limitations of those aesthetics. Not only do Pullman and Port Sunlight reflect an important shift in spatial practices during the 1880s, their architects and landscape architects became influential leaders in the visual ideologies of the City Beautiful and Garden City planning movements.     

An investigation of the fractal properties of flint microwear images

This paper reports on an investigation into the fractal dimensions of flint microwear images which has been carried out in an attempt to resolve the existing controversy over the possibility of identifying microwear types from visual inspection of high magnification images, and describes a new method for flint microwear image analysis based on fractal geometry. Fractal dimensions of surface images, which are known to relate well to human visual perception of roughness, have been computed for various types of microwear. No significant correlations have been found between the fractal properties of the digital flint images and the contacted materials.
