Advanced Value Chain Collaboration in Ghana's Cocoa Sector: An Entry Point for Integrated Landscape Approaches?

Value chain analyses have focused mainly on collaboration between chain actors, often neglecting collaboration "beyond the chain" with non-chain actors to tackle food security, poverty and sustainability issues in the landscapes in which these value chains are embedded. Comparing conventional and advanced value chain collaborations involving small-scale cocoa farmers in Ghana, this paper analyzes the merits of a more integrated approach toward value chain collaboration. It particularly asks whether advanced value chain collaboration targeting cocoa-producing areas potentially offers an entry point for implementing a landscape approach.

Magnetic resonance imaging in gynecological oncology.

Magnetic resonance imaging (MRI) has become an indispensable tool in the assessment of malignant disease. With increasingly sophisticated systems and technical advancements, MRI has continued to expand its role in providing crucial information regarding cancer diagnosis and management. In gynecological malignancies, this modality has assumed greater responsibility, particularly in the evaluation of cervical and endometrial cancers.

Variable size computer-aided detection prompts and mammography film reader decisions.

Introduction: The purpose of the present study was to investigate the effect of computer-aided detection (CAD) prompts on reader behaviour in a large sample of breast screening mammograms by analysing the relationship of the presence and size of prompts to the recall decision.

Methods: Local research ethics committee approval was obtained; informed consent was not required. Mammograms were obtained from women attending routine mammography at two breast screening centres in 1996.

Visually assessed breast density, breast cancer risk and the importance of the craniocaudal view.

Introduction: Mammographic density is known to be a strong risk factor for breast cancer. A particularly strong association with risk has been observed when density is measured using interactive threshold software. This, however, is a labour-intensive process for large-scale studies.

Effects of secondary prevention clinics on health status in patients with coronary heart disease: 4 year follow-up of a randomized trial in primary care.

Background: The long-term effects of disease management programmes for coronary heart disease on health status are unknown. In a randomized trial of nurse-led secondary prevention clinics, we found significantly improved health status at 1 year. Participants were followed-up again at 4 years to determine if improvements had been sustained.
