We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present them as viable alternatives to tellurite glasses for applications requiring highly nonlinear optical fibers. © 2013 Optical Society of America.

This report proposes a framework for locating, collecting, creating, sharing and applying information and knowledge (from within and outside the subregion) for development purposes in the Caribbean subregion. The framework emphasizes the importance of protecting and tapping into the rich cultural heritage and traditional knowledge of the Caribbean to support its development. This knowledge management for development framework, advanced by ECLAC, is proposed for consideration in the design and implementation of both national policies and strategies, and communitylevel projects to support the achievement of the Millennium Development Goals and the overall sustainable development of the Caribbean subregion. It considers six main elements, namely inputs, processes and tools, outputs, pillars (on which all the above are built on), the environment or context in which this, like any other scheme, operates and the monitoring and evaluation of knowledge management initiatives. The approach draws from examples of models, frameworks and initiatives developed worldwide, with particular emphasis on those from Latin America and the Caribbean.
