Relative Sensitivity Of Two Marine Bivalves For Detection Of Genotoxic And Cytotoxic Effects: A Field Assessment In The Tamar Estuary, South West England., Lorna J. Dallas, Victoria V. Cheung, Andrew S. Fisher, Awadhesh N. Jha Jan 2013

Relative Sensitivity Of Two Marine Bivalves For Detection Of Genotoxic And Cytotoxic Effects: A Field Assessment In The Tamar Estuary, South West England., Lorna J. Dallas, Victoria V. Cheung, Andrew S. Fisher, Awadhesh N. Jha

School of Geography, Earth and Environmental Sciences

The input of anthropogenic contaminants to the aquatic environment is a major concern for scientists, regulators and the public. This is especially relevant in areas such as the Tamar valley in SW England, which has a legacy of contamination from industrial activity in the nineteenth and twentieth centuries. Following on from previous laboratory validation studies, this study aimed to assess the relationship between genotoxic and cytotoxic responses and heavy metal concentrations in two bivalve species sampled from locations along the Tamar estuary. Adult cockles, Cerastoderma edule, and blue mussels, Mytilus edulis, were sampled from five locations in the Tamar and …

Rural Non-Farm Livelihood Diversification And Poverty Reduction In Nigeria, Paul Agu Igwe

Plymouth Business School Theses

The aim of this research is to provide analysis of the rural non-farm sector in Nigeria by investigating inter-linkages between farm and non-farm activities. By critical analysis using quantitative and qualitative research methods to investigate farm and non-farm sectors, the research attempts to reveal the complex linkages between these activities undertaken by rural households. The analysis employs household surveys aimed at collecting primary data undertaken to investigate various aspects of rural livelihoods including sources of income, employment, diversification and determinants of household income. The research provides analysis of Rural Micro and Small Enterprises (RMSEs) in the non-farm sector. It investigates …


The Construction Of Local Road Safety Issues: When Lay And Professional Discourses Collide, Stephen Ball Jan 2013

The Construction Of Local Road Safety Issues: When Lay And Professional Discourses Collide, Stephen Ball

Plymouth Business School Theses

Highway Authorities in the United Kingdom have jurisdiction to control, maintain and improve the local highway network, and the Road Traffic Act 1988 places a duty on such authorities to take preventative measures to reduce road casualties. As such, engineers working for the Highway Authority are on the ‘front-line,’ and are required to deal directly with lay concerns relating to road safety. This study investigates the nature and characteristics of how local road safety issues are raised and how engineers respond to such issues in a local authority setting. A grounded theory methodology was applied in the collection and analysis …


Investigating The Effects Of Corporate Governance Of Banks In Nigeria: A Grounded Theory Approach, Umar Abbas Ibrahim Jan 2013

Investigating The Effects Of Corporate Governance Of Banks In Nigeria: A Grounded Theory Approach, Umar Abbas Ibrahim

Plymouth Business School Theses

This thesis investigates the phenomena that underlie corporate governance practices in the Nigerian banking sector (NBS); the purpose is to understand the nature of corporate governance and the factors influencing it. It offers a response to a number of concerns raised about the effectiveness of banks’ corporate governance practices, especially before the consolidation reform and during the 2007-2009 global financial crisis. Culture and leadership are identified as providing the most suitable theoretical framework for this study, and through grounded theory (GT), an empirical study is undertaken to identify the nature of corporate governance practices in banks, the factors that influence …


Election Data Visualisation, Elena Long Jan 2013

Election Data Visualisation, Elena Long

Plymouth Business School Theses

Visualisations of election data produced by the mass media, other organisations and even individuals are becoming increasingly available across a wide variety of platforms and in many different forms. As more data become available digitally and as improvements to computer hardware and software are made, these visualisations have become more ambitious in scope and more user-friendly. Research has shown that visualising data is an extremely powerful method of communicating information to specialists and non-specialists alike. This amounts to a democratisation of access to political and electoral data. To some extent political science lags behind the progress that has been made …
