Market organisation and the process of economic development: the case of the partially liberalised cocoa market in Ghana.

Within the last twenty years the link between market organisation and development has come under increased scrutiny in response to the implementation of World Bank liberalisation policies across many of sub-Saharan Africa's agriculture markets. Under the neoliberal teachings of the Washington Consensus, liberalised markets have replaced systems of government control, with disappointing results. Recognising the challenges created by the universal implementation of liberalisation policies, the attention of development economists, including the World Bank, has now turned to alternative modes of market organisation. In light of this, the following study aims to contribute to the post Washington Consensus understanding of market development through a detailed exploration of the Ghanaian cocoa market as an alternative model for market organisation within sub-Saharan agriculture. The Ghanaian cocoa market has been selected because, in contrast with its fully liberalised cocoa producing neighbours, Ghana has only undergone partial liberalisation. The Ghanaian Cocoa Board [Cocobod] maintains control over several functions across both the domestic and international dimensions of the Ghanaian cocoa chain. Given the span of the Cocobod's influence along the Ghanaian cocoa chain, it has been necessary to develop a cross disciplinary theoretical framework, using New Institutional Economics for a microanalysis of the domestic cocoa chain, and Global Value Chain analysis for a macro-analysis of the international cocoa chain. Building on a critique of the universalism inherent within the Washington Consensus, methodologically this study has attempted to achieve an in-depth understanding of the Ghanaian cocoa market. In line with the ontological approach of critical realism, this has involved the use of semi-structured qualitative interviews, throughout two independent rounds of research in Ghana. Interview data has been systematically organised and interpreted using the approach of template analysis. Based on the construction of six final templates it has been possible to deduce that direct government intervention in the areas of quality control, enforcement and a monopoly over cocoa exports appear to be having a positive impact upon market development in Ghana. Equally, it has been observed that the Cocobod may be failing to leverage the potential of private sector investment, as it struggles to adapt to partial liberalisation. In closing it is recommended that future research into models of partial liberalisation should be pursued based on the results of this study

Genomic–based optimum contributions in conservation and genetic improvement programmes with antagonistic fitness and productivity traits

Animal selection for genetic improvement of productivity may lead to an increase in inbreeding through the use of techniques that enhance the reproductive capability of selected animals. Therefore, breeding strategies aim to balance maintaining genetic variability and acceptable fitness levels with increasing productivity. The present study demonstrates the effectiveness of genomic-based optimum contribution strategies at addressing this objective when fitness and productivity are genetically antagonistic traits. Strategies are evaluated in directional selection (increasing productivity) or conservation (maintaining fitness) scenarios. In the former case, substantial rates of genetic gain can be achieved while greatly constraining the rate of increase in inbreeding. Under a conservation approach, inbreeding depression can be effectively halted while also achieving a modest rate of genetic gain for productivity. Furthermore, the use of optimum contribution strategies when combined with a simple non-random mating scheme (minimum kinship method) showed an additional delay in the increase of inbreeding in the short term. In conclusion, genomic-based optimum contribution methods can be effectively used to control inbreeding and inbreeding depression, and still allow genetic gain for productivity traits even when fitness and productivity are antagonistically correlated

Taking stock: a visual analysis of gendered ageing

While various forms of imagery have been highlighted as central to processes of social construction, the potential of visual methodologies to generate insight into gendered ageing has yet to be fully exploited. We build on the developing body of visual analyses within work and organization studies to suggest how understandings of gendered ageing are impacted by our consumption of work-related images, empirically explored here using stock photographs. We examine images of men and women of various ages to unpack the visual construction of gendered ageing within online news media, a critical context within the new economy. Through our own analysis, and our review of participants’ responses to three images, we contribute to the unpacking of culturally produced age-sensitive subject positions through examination of the interrelationships between gender, age and employment. These combined methodologies offer new insights into ways in which understandings of gendered ageing are both (visually) constructed and interpreted

Person-Related Protective and Vulnerability Factors of Psychopathology Symptoms in Non-Clinical Adolescents

Psychopathology in youths is thought to originate from a dynamic interplay of a variety of protective and vulnerability factors. In this study, a large multi-ethnic sample of non-clinical adolescents (N = 376) completed questionnaires for measuring a wide range of person-related protective and vulnerability factors as well as psychopathology symptoms, in order to explore (a) the relations among various protective and vulnerability factors, and (b) the unique contributions of these protective and vulnerability factors to different types of psychological problems. Results indicated that the overlap among protective and vulnerability factors was quite modest. Further, it was found that factors clustered in theoretically meaningful components reflecting protection, vulnerability, and more specific aspects of coping and social support. Finally, data indicated that each type of psychopathology symptoms was associated with a typical set of protective and vulnerability factors. Although these results should be interpreted with caution because of the cross-sectional nature of the study, they may nevertheless guide future research exploring multifactorial models of psychopathology in youths
