The manufacture and utilisation of architectural terracotta and faience.

The revival of terracotta and faience in British architecture was widespread, dramatic in its results and, for two decades, the subject of intense debate. However the materials have been frequently denigrated and more generally disregarded by both architects and historians. This study sets out to record and explain the rise and fall of interest in terracotta and faience, the extent and nature of the industry and the range of architectural usage in the Victorian, Edwardian and inter-war periods. The first two chapters record the faltering use of terracotta as an 'artificial stone', until the material gained its own identity, largely through the appreciation of Italian architecture. In the mid-Victorian period, terracotta will be seen to have become symbolic of the philosophy of the Victoria and Albert Museum and its Art School in attempting to reform both architecture and the decorative arts. The adoption of terracotta was furthered as much by industrial as aesthetic factors; three chapters examine how the exploitation of coal-measure clays, developments in the processes of manufacture, the changing motivation of industrialists and differing economics of production served to promote and then to hinder expansion and adaptation. The practical values of economy, durability and fire-resistance and the aesthetic potential, seen in terms of colour and decorative and sculptural modelling, became inter-related in the work of the architects who made extensive use of architectural ceramics. A correlation emerges between the free Gothic style, exemplified by the designs of Alfred Waterhouse and the use of red terracotta supplied from Ruabon, and between the eclectic Renaissance style and a buff material produced by different manufacturers.These patterns were modified as a result of the adoption of faience for facing external walls as well as interiors, and because of the new architectural requirements and tastes of the twentieth century. The general timidity in exploiting the scope for polychromatic decoration and the increasing opposition to architectural ceramics is contrasted with the most successful schemes produced for cinemas, chain-stores and factories. In the last chapter, those undertaken by the Hathern Station Brick and Terracotta Company between 1896 and 1939 are used as a case study; they confirm that manufacturers, architects and clients were all committed to creating a modern and yet decorative architecture, appropriate for new building types and that would appeal to and be comprehensible to the public.

Corporate legitimacy and advertising:British companies and the rhetoric of development in West Africa, 1950-1970

Development, modernity, and industrialization became dominant themes in corporate advertising in Africa in the 1950s and remained prevalent through the following two decades while many African nations were gaining independence. British business operating there created a publicity strategy that couched their presence in less developed countries in terms of a commitment and a positive contribution to the progress of the new states. Eventually, British companies tried to "Africanize" their corporate image through these campaigns.

Thermochemical characterisation of agricultural wastes from West Africa

Thermochemical characterisation of agricultural biomass wastes from West African region has been carried out and their potential use as feedstock in thermochemical conversion processes determined. Proximate, ultimate, structural compositions, calorific values, thermogravimetry (TGA) and derivative thermogravimetry (DTG) analyses were carried out on corn straw and cobs, rice straw and husks, cocoa pod, jatropha curcas and moringa olifiera seed cakes, parinari polyandra fruit shell and sugarcane bagasse. Moringa olifiera seed cakes and cocoa pods were found to contain the highest moisture contents. Rice straw was found to contain a high ash content of 45.76. wt.%. The level of nitrogen and sulphur in all the samples were very low. Rice husk was found to have the highest lignin contents while corn cob low lignin contents indicate a potential feedstock source for quality bio-oil production using thermochemical process. © 2013.

Postcolonial transitions in Africa:Decolonization in West Africa and present day South Africa

Black Economic Empowerment is a highly debated issue in contemporary South Africa. Yet few South Africans realize that they are following a postcolonial trajectory already experienced by other countries. This paper presents a case study of British firms during decolonization in Ghana and Nigeria in the 1950s and 1960s, which saw a parallel development in business and society to that which occurred in South Africa in the 1990s and 2000s. Despite fundamental differences between these states, all have had to empower a majority of black citizens who had previously suffered discrimination on the basis of race. The paper employs concepts from social capital theory to show that the process of postcolonial transition in African economies has been more politically and socially disruptive than empowerment in Western countries. Historical research contributes to our understanding of the nature of institutional shocks in emerging economies.

"No longer at ease":corruption as an institution in West Africa

This article traces the historical genesis of corruption in two West African countries: Ghana and Nigeria. It argues that corruption in Africa is an institution that emerged in direct response to colonial systems of rule which super-imposed an imported institutional system with different norms and values on an existing institutional landscape, despite the fact that both deeply conflicted and contradicted each other. During decolonization and after independence, corruption, although dysfunctional, fully evolved into an institution that allowed an uneasy cohabitation of colonial and domestic African institutions to grow into a composite, syncretic system facilitated by generalized corruption.

Leadership and management research in Africa:a synthesis and suggestions for future research

Although we are aware of some positive cases of leadership and management emerging on the African continent, very little empirical or theoretical work has addressed leadership and management in Africa. This raises a challenge for African nations in that ultimately a country's economic performance is contingent on the effectiveness of its leadership and management practices that serve to unlock the potential of its workforce to effectively implement the strategic goals of organizations. Against the backdrop of an increasingly knowledge-dependent global marketplace, the centrality of leadership and effective management systems as drivers of individual and organization performance has never been more critical. This special section brings together a compendium of papers that advances the science of leadership and management within the African context. Our principle goal was to examine what is unique, what generalizes, and what does not generalize from the West and East to Africa, as well as within different regions of Africa and then offer ideas to guide future research and practice. The papers in this section provide a broad and indeed innovative approach to studying leadership and management in Africa by including historical, philosophical, economic, and socio-political perspectives, as part of the analyses of leadership and management in the African context. Our editorial provides an integration of this work and a launching point for some audacious goals for future leadership and management science and practice in Africa and beyond. ©2011 The British Psychological Society.
