THE DETERMINANTS OF ECO-LABEL USAGE IN THE ORGANIC PRODUCE MARKET OF NORTHEAST ARKANSAS

This study used consumer intercept interviews at farmers markets and organic produce retail stores in northeast Arkansas to determine the variables that influence eco-label usage in organic produce markets. The results indicate that females, those with higher annual incomes, consumers who believe the use of pesticides has negative impact on health and the environment, and those who usually organic purchase organic produce are all more likely to use eco-labels in purchasing organic produce. The findings also suggest that there is a direct relationship between income levels and marginal probability of eco-label usage. The result of this study provides a more current picture of the major determinants that influence eco-label usage among consumers which will be valuable as the USDA proposed organic standards are implemented in the market.Marketing,

Regionalism, Food Security and Economic Development

It is remarkable that Africa, with enormous resource endowments and with more than 70 percent of the population engaged in agriculture, cannot feed itself. This background paper offers a critical assessment of the potential of regional trade and integration in addressing the enduring challenge of food insecurity in Africa. Drawing on the literature, the paper argues that regionalism offers enormous opportunities and synergies for enhancing economic growth, food supply, and stability of food prices that cannot be easily addressed by individual countries when they operate in isolation from each other. To demonstrate the potential of regional integration for achieving food security in Africa, this paper starts by providing a conceptual framework that outlines the dimensions that link regional cooperation and food security. An overview of the key policy initiatives that are currently underway at enhancing integration at the continental level and in various regional blocs follows this introduction. The paper then progresses to a review of the extent of economic integration among African countries, with particular focus on the agriculture and food trade. It then presents a discussion on potential areas of integration followed by an examination of capacity issues that need policy attention in order to improve the potential of continental and regional integration in improving national and household food security among African countries

Enhancing Spatial Data Accessibility in Ghana: Prioritization of Influencing Factors Using AHP

The Analytic Hierarchy Process (AHP) is a general problem-solving method that is useful in making complex, multi-criteria and multi-stakeholder decisions based on variables that have or do not have exact numerical consequences. AHP was applied to structure a multi-criteria decision problem regarding access to spatial data in Ghana; and to determine the priorities of spatial data accessibility components and influencing factors. A three-level AHP structure was constructed to examine the spatial data access problem, with a main objective, four sub-objectives and five alternatives. Spatial data accessibility was decomposed into four components (discoverability, retrievability, usability and affordability) which were used as sub-objectives (criteria). More so, spatial data access is mediated by affective factors (institutional, technical, policy/legal, socio-cultural and economic) which were used as alternatives. Fifty individuals from twenty four organizations were interviewed and later engaged in focus-group discussion to generate weights (priorities) for the accessibility components and the alternatives. The results provide both qualitative and quantitative information to decision makers regarding the spatial data access problem and their priorities from the perspective of enhancing access to spatial data. Regarding accessibility components (objectives), discoverability and retrievability had the highest priorities while technical and institutional issues had the highest priorities with regard to the affective factors. Considering the overall impact on the main objective and in the face of limited resources, it is concluded that improvement in the technical and institutional environment with the view to improving discoverability and retrievability require the highest priority in order to enhance access to spatial data in Ghana

Immunogenicity and efficacy of oral vaccines in developing countries: lessons from a live cholera vaccine

Oral vaccines, whether living or non-living, viral or bacterial, elicit diminished immune responses or have lower efficacy in developing countries than in developed countries. Here I describe studies with a live oral cholera vaccine that include older children no longer deriving immune support from breast milk or maternal antibodies and that identify some of the factors accounting for the lower immunogenicity, as well as suggesting counter-measures that may enhance the effectiveness of oral immunization in developing countries. The fundamental breakthrough is likely to require reversing effects of the 'environmental enteropathy' that is often present in children living in fecally contaminated, impoverished environments

Cerebral malaria in children: using the retina to study the brain

Cerebral malaria is a dangerous complication of Plasmodium falciparum infection, which takes a devastating toll on children in sub-Saharan Africa. Although autopsy studies have improved understanding of cerebral malaria pathology in fatal cases, information about in vivo neurovascular pathogenesis is scarce because brain tissue is inaccessible in life. Surrogate markers may provide insight into pathogenesis and thereby facilitate clinical studies with the ultimate aim of improving the treatment and prognosis of cerebral malaria. The retina is an attractive source of potential surrogate markers for paediatric cerebral malaria because, in this condition, the retina seems to sustain microvascular damage similar to that of the brain. In paediatric cerebral malaria a combination of retinal signs correlates, in fatal cases, with the severity of brain pathology, and has diagnostic and prognostic significance. Unlike the brain, the retina is accessible to high-resolution, non-invasive imaging. We aimed to determine the extent to which paediatric malarial retinopathy reflects cerebrovascular damage by reviewing the literature to compare retinal and cerebral manifestations of retinopathy-positive paediatric cerebral malaria. We then compared retina and brain in terms of anatomical and physiological features that could help to account for similarities and differences in vascular pathology. These comparisons address the question of whether it is biologically plausible to draw conclusions about unseen cerebral vascular pathogenesis from the visible retinal vasculature in retinopathy-positive paediatric cerebral malaria. Our work addresses an important cause of death and neurodisability in sub-Saharan Africa. We critically appraise evidence for associations between retina and brain neurovasculature in health and disease, and in the process we develop new hypotheses about why these vascular beds are susceptible to sequestration of parasitized erythrocytes

Forging connections: anthologies, arts collectives, and the politics of inclusion

The changing social and political landscape of twentieth-century Britain catalysed a remarkable rise in collaborative activity by artists and activists of black and Asian heritage. Creative communities began to gather in both local and regional contexts, with the aim of sharing resources and securing an audience. This chapter records some of these many activities, tracing the groups’ genesis, manifest objectives, and key contributions. It argues that anthologising should be understood as a specifically motivated activity. Literary anthologies of poetry and fiction served to showcase the diversity of contemporary writing, while also suggesting its coherence. Drawing on the concept of “strategic essentialism” elucidated by Gayatri Chakravorty Spivak, I show that the anthology acts to ensure the visibility of a group, bannered as a unified and singly-titled selection of texts, while also insisting on the differences within: the heterogeneous multiplicity of black and Asian British experiences and creative practices

'Vernacular Voices: Black British Poetry'

ABSTRACT Black British poetry is the province of experimenting with voice and recording rhythms beyond the iambic pentameter. Not only in performance poetry and through the spoken word, but also on the page, black British poetry constitutes and preserves a sound archive of distinct linguistic varieties. In Slave Song (1984) and Coolie Odyssey (1988), David Dabydeen employs a form of Guyanese Creole in order to linguistically render and thus commemorate the experience of slaves and indentured labourers, respectively, with the earlier collection providing annotated translations into Standard English. James Berry, Louise Bennett, and Valerie Bloom adapt Jamaican Patois to celebrate Jamaican folk culture and at times to represent and record experiences and linguistic interactions in the postcolonial metropolis. Grace Nichols and John Agard use modified forms of Guyanese Creole, with Nichols frequently constructing gendered voices whilst Agard often celebrates linguistic playfulness. The borders between linguistic varieties are by no means absolute or static, as the emergence and marked growth of ‘London Jamaican’ (Mark Sebba) indicates. Asian British writer Daljit Nagra takes liberties with English for different reasons. Rather than having recourse to established Creole languages, and blending them with Standard English, his heteroglot poems frequently emulate ‘Punglish’, the English of migrants whose first language is Punjabi. Whilst it is the language prestige of London Jamaican that has been significantly enhanced since the 1990s, a fact not only confirmed by linguistic research but also by its transethnic uses both in the streets and on the page, Nagra’s substantial success and the mainstream attention he receives also indicate the clout of vernacular voices in poetry. They have the potential to connect with oral traditions and cultural memories, to record linguistic varieties, and to endow ‘street cred’ to authors and texts. In this chapter, these double-voiced poetic languages are also read as signs of resistance against residual monologic ideologies of Englishness. © Book proposal (02/2016): The Cambridge History of Black and Asian British Writing p. 27 of 4
