New technologies are generally perceived as the basic tool for survival in modern society. But the extent of their availability and use, as well as their impact on newspaper journalism practice in West Africa is unknown. This paper presents the results of a study that investigated the impact of new technologies on newspaper journalism practice in two West African countries — Nigeria and Ghana. The study, conducted in five newspapers in the two countries, found that, although a majority of the journalists believed the new technologies have improved the quality of their newspapers, fewer than half of the journalists were unimpressed with the level of the technologies available to them in the performance of their duties.

Soil erosion is one of the most pressing issues facing developing countries. The need for soil erosion assessment is paramount as a successful and productive agricultural base is necessary for economic growth and stability. In Ghana, a country with an expanding population and high potential for economic growth, agriculture is an important resource; however, most of the crop production is restricted to low technology shifting cultivation agriculture. The high intensity seasonal rainfall coincides with the early growing period of many of the crops meaning that plots are very susceptible to erosion, especially on steep sided valleys in the region south of Lake Volta. This research investigated the processes of soil erosion by rainfall with the aim of producing a sediment yield model for a small semi-agricultural catchment in rural Ghana. Various types of modelling techniques were considered to discover those most applicable to the sub-tropical environment of Southern Ghana. Once an appropriate model had been developed and calibrated, the aim was to look at how to enable the scaling up of the model using sub-catchments to calculate sedimentation rates of Lake Volta. An experimental catchment was located in Ghana, south west of Lake Volta, where data on rainstorms and the associated streamflow, sediment loads and soil data (moisture content, classification and particle size distribution) was collected to calibrate the model. Additional data was obtained from the Soil Research Institute in Ghana to explore calibration of the Universal Soil Loss Equation (USLE, Wischmeier and Smith, 1978) for Ghanaian soils and environment. It was shown that the USLE could be successfully converted to provide meaningful soil loss estimates in the Ghanaian environment. However, due to experimental difficulties, the proposed theory and methodology of the sediment yield model could only be tested in principle. Future work may include validation of the model and subsequent scaling up to estimate sedimentation rates in Lake Volta.

The article expands existing categorisations of political and economic governance by including literature on less developed countries (LDCs). In four consecutive negotiations between the US multinational Kaisers and the US and Ghana governments in the early 1960s, it is argued that the company reached levels of influence that are at odds with existing explanations. In order to understand corporate political activities in LDCs, analysis needs to go beyond static factors (political risk) and include dynamic factors such as diplomatic relations and 'arenas of power', and consider the role of the investor's home country relative to the host economy.

This paper considers the lives of children living in a large informal settlement in central Accra, Ghana. Its contention is that children remain largely absent from the renewal of interest in slums and that where they do feature it is largely as objects of risk and vulnerability. Such an exclusive focus, it is argued, risks effacing the ways in which children are capable of actively confronting the terrible constraints posed by slum environments and the 'talent for living' that this involves. Drawing upon the findings of a small qualitative exploratory research project, the paper examines sources of support and cooperation between children and how their decisions to work are perceived as a strategy to actively support mothers and families struggling for a subsistence. © 2011 The Author(s).

What is discussed in this chapter is work-in-progress, an opportunity for reflection upon elements of an on-going research project examining the lives of street children in Accra, Ghana. Street children have received much research in recent years but our project is, we believe, distinctive in two respects. The first of these is that access to reliable data on the growing presence of children on the streets of African cities is often problematic. Available research is often diffuse and hard to access, it is more often than not driven by the short-term requirements of specific programmes and interventions and as a consequence can be lacking in depth, rigour and innovation. Without the means to provide a sufficiently self-conscious and critical engagement with accepted understandings of the lives of street children, consideration of the experience of street children in Africa continues to rely heavily on the more capacious and better disseminated research from the Americas (e.g., Mickelson, 2000). At the very least, Africa's specific experience of large population displacements, diversity of family forms, rapid urbanisation, vigorous structural adjustment and internal conflict raise important questions about the appropriateness of such ready generalisations. Judith Ennew (2003, p. 4) is clear that caution is needed in an uncritical endorsement of the “globalisation of the street child based on Latin American work”. She is equally mindful, however, that as far as Africa is concerned the absence of reliable evidence continues to hinder debate.

Why has Corporate Social Responsibility (CSR) yielded such disappointing outcomes in oil-rich sub-Saharan Africa? Over the past decades, a sizable body of literature has emerged which draws attention to the shortcomings of oil-related development and complementary CSR exercises in the region. Most critiques on the topic, however, assess specific interventions and/or policies but fail to evaluate the complex decision-making processes, dictated heavily by setting, which produce such actions altogether. This thesis attributes CSR outcomes in oil-rich sub-Saharan Africa to the unique context in which the decisions underpinning actions take place. In doing so, the analysis borrows ideas from a diverse body of literature spanning the international development, accounting, management and political science disciplines. To explore these ideas further, the thesis focuses on the case of Ghana. The most recent “addition” to sub-Saharan Africa’s oil club, Ghana provides a rare glimpse of how decisions underpinning CSR have been identified, evolved and reshaped from the outset. To provide a comprehensive picture of CSR in the sector and its impacts at the local level, interviews and focus groups were conducted with a range of stakeholder groups. As is the case throughout sub-Saharan Africa, in Ghana, oil production occurs in offshore “enclaves”, which are disconnected geographically from local communities. This thesis argues that these dynamics have important implications for CSR. Findings point to companies also being disconnected ideologically from local development needs, which, in part explains the questionable CSR that has become such a contentious issue in the debate on oil and development in sub-Saharan Africa in recent years. The enclave-type setting in which oil production occurs appears to have stifled creativity and innovation in the area of CSR. This, along with institutional weaknesses, regulatory deficiencies and the Government of Ghana’s failure to adequately respond to local-level concerns, has produced these outcomes.

Herman Chinery-Hesse considers his plans for a new venture, a virtual mall that would enable African producers to sell their products worldwide through a new international payment system based on mobile phones and pre-paid scratch cards. In 2010, his operating company, Black Star Lines (BSL) Ghana Ltd is considering plans to launch shopAfrica53.com, and associated payment and distribution services in Ghana and the UK. This case teaches new approaches to poverty reduction through the realisation of entrepreneurial opportunities at the Bottom of the Pyramid (BoP) and is suitable for courses on social enterprise, entrepreneurship in general, and development studies seeking to incorporate more private sector approaches. It can also be adapted for courses such as international strategy or technology business.

The purpose of this inquiry was to investigate the perceptions of former service personnel, students and their parents about the organizational effectiveness of the Ghana National Service Scheme (GNSS). The inquiry addressed the following questions: How do the participants perceive the effectiveness of the national service program on the Ghanaian society? What are the perceptions of school administrators who worked with service personnel, parents and students vis-à-vis the over all impact of the GNSS on the educational system? What are the perceptions of former service personnel, students and their parents in regard to the impact of the GNSS on them? ^ The GNSS is a part within the ministry of education, which is also part in the Ghanaian social structure. Hence, a systems theory approach which asks, “How and why a system as a whole functions as it does” (Patton, 1990), was utilized in the study. Methodologies included purposive sampling; interviews; participant observation, and follow-up interviews. The study was conducted over a six-moth period. ^ A cross-sectional survey design was used to generate data. The survey was followed up with an ethnographic study where in-depth, face-to-face interviews were conducted together with observations. The results were described and interpreted. ^ The summary of findings concludes that perceptional determinants of the effectiveness of the GNSS were biased by the age and zone of origin but not gender. This partially agrees with Marenin's (1990) except for gender. A significant difference was detected between the responses of those who were officials of the National service Secretariat and of former service personnel. The administrators defended the status quo and demonstrated their deeper knowledge about the scheme. The former personnel and parents freely criticized the program when necessary and did not seem to know much about the GNSS. Respondents mostly stressed the need for the secretariat to focus on the following areas: (1) involvement in the agricultural sector of the economy, (2) involvement in rural mass, civic and health education, (3) adequacy of remuneration and personnel welfare, and (4) ensuring posting of personnel to areas of their expertise. Recommendation for further research concluded the study. ^

Limited literature exists on Ghana's child domestic servants, and researchers have found it difficult to locate and study these children. The research for this dissertation used qualitative research methodologies and non-probabilistic sampling techniques to make it possible to interview child domestic servants, their parents, employers and recruiters in Ghana. The findings from the qualitative analyses informed the second part of this study, which was quantitative and tested hypotheses using crosstabulations and logistic regression analyses that were based on survey data from the Ghana Statistical Service. Explanatory variables in the quantitative analyses included lineage, level of education and relationships to the household head. ^ This study located findings about the processes of children's recruitment into domestic servitude, their working conditions and methods of remuneration in theories of slavery to answer the question of whether or not child domestic servants are slaves. According to the findings, elite households in Ghana exploit children from rural regions because they have taken advantage of a historical practice that allowed children to live with older members of their extended families to provide domestic services and in return, be given the chance to receive formal education or to learn a trade. The participants in the qualitative part of this research described the treatments that they receive from their employers as slavery. Nevertheless, the processes of their recruitment and the age at which most of them accepted such job offers made it difficult to categorize a majority of them as contemporary slaves. ^
