Quality Assurance in Ghana: Accomplishments and Challenges

Constructing a Transnational Timber Legality Assurance Regime: Architecture, Accomplishments, Challenges

The emerging transnational timber legality assurance regime comprises a set of interrelated policy instruments, both public and private, aimed at controlling trade in illegally logged wood and wood products. The potentially productive interactions among these instruments in the emerging forestry regime create prospects for engendering learning, stimulating crossfertilization, and enhancing acco...

IPCC: accomplishments, controversies and challenges

The Intergovernmental Panel on Climate Change (IPCC) has successfully produced four assessment reports since 1990 along with a number of special reports and greenhouse gas inventory guidelines. It has very rigorous and robust procedures and guidelines for preparing the assessment reports largely based on synthesis of peer-reviewed and published scientific literature. IPCC has attracted controve...

Chiral surfaces: accomplishments and challenges.

Chiral surfaces serve as media for enantioselective chemical processes. Their chirality is dictated by atomic- and molecular-level structure, and their enantioselectivity is determined by their enantiospecific interactions with chiral adsorbates. This Perspective describes three types of chiral metal surfaces: those modified by adsorption of chiral molecules, those templated by chiral lattices ...

Quality Assurance in Model-Based Software Development: Challenges and Opportunities

Modeling is a common practice in modern day software engineering. Since the mid 1990‟s the Unified Modeling Language (UML) has become the de facto standard for modeling software systems. The UML is used in all phases of software development – ranging from the requirements phase to the maintenance phase. However, the manner in which the UML is used differs widely from project to project and from...
