The key to a successful repository is sustained deposits, and the key to sustained deposits is community engagement. This paper looks at deposit profiles automatically generated from OAI harvesting information and argues that repositories characterised by occasional large-volume deposits are a sign of a failure to embed in institutional processes. The ideal profile for a successful repository i...

objective: taro (colocasia esculenta l. schott) is a perennial root crop that belongs to araceace family.  it is widely cultivated as a staple food in africa, asia and pacific islands. despite its importance, there is limited information on many aspects of the crop. in order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effect...

Very high resolution satellite images are used to derive the spatial distributions of landscape ecological metrics within suburban areas. These indicators are weighted mean patch size and lacunarity computed from thresholded normalized difference vegetation index obtained from multispectral IKONOS-2 imagery. Spatial distributions of the metrics are derived for an extensive suburban area on the ...

Abstract—Arising problems of countries’ public finances, social and demographic changes motivate scientific and policy debates on public spending size, structure and efficiency in order to meet the changing needs of society and business. The concept of sustainable development poses new challenges for scientists and policy-makers in the field of public finance. This paper focuses on the investig...

This paper develops a sustainable yield harvesting model for the wild Atlantic salmon (Salmo salar), where the population comprises different age classes. It is shown that the weight– fecundity relationship of the spawning population, comprising young and old fish, is crucial for the maximum sustainable yield fishing composition. First, the optimal harvest is found when fecundity is approximate...

realistically and justifiably allocated to protected areas? And perhaps even more importantly, on the remaining actively managed landscape, what forest management practices should be employed and how can these be encouraged? Answers to these questions must be adaptive to evolving models of sustainable ecosystem management as well as geopolitical context and local community involvement. In this ...
