title: Coping with design complexity: a conceptual framework for design alternatives and variants

authors: Bowen, Judy

subjects: computer science

abstract: Interaction design processes are characterised by multi-disciplinary teamwork and by an interplay of creative, situated and analytical thinking. Although design in the domain of human-computer interaction has been widely investigated, the focus of research has been mainly on the user’s role and several authors refer to the need for a deeper understanding of the increasingly complex interaction design processes. This paper suggests a conceptual framework for interaction design that accommodates and unifies different perspectives from general design research while considering the specificities of the domain. Within the framework, description and analysis is done through the lens of design spaces, design artefacts, and refinement relationships between design artefacts. The framework extends existing concepts of design spaces by introducing complex spaces which acknowledge that design is rarely an individual activity but is more often undertaken by teams of designers. The framework also offers a distinction between design options into alternatives and variants to better describe and guide processes of idea generation and a convergence within, and between different sub-spaces and sub-teams. Different types of refinement between design artefacts are also discussed.

title: High exposure of global tree diversity to human pressure.

authors: Guo, Wen-Yong

subjects: biodiversity

abstract: Safeguarding Earth's tree diversity is a conservation priority due to the importance of trees for biodiversity and ecosystem functions and services such as carbon sequestration. Here, we improve the foundation for effective conservation of global tree diversity by analyzing a recently developed database of tree species covering 46,752 species. We quantify range protection and anthropogenic pressures for each species and develop conservation priorities across taxonomic, phylogenetic, and functional diversity dimensions. We also assess the effectiveness of several influential proposed conservation prioritization frameworks to protect the top 17% and top 50% of tree priority areas. We find that an average of 50.2% of a tree species' range occurs in 110-km grid cells without any protected areas (PAs), with 6,377 small-range tree species fully unprotected, and that 83% of tree species experience nonnegligible human pressure across their range on average. Protecting high-priority areas for the top 17% and 50% priority thresholds would increase the average protected proportion of each tree species' range to 65.5% and 82.6%, respectively, leaving many fewer species (2,151 and 2,010) completely unprotected. The priority areas identified for trees match well to the Global 200 Ecoregions framework, revealing that priority areas for trees would in large part also optimize protection for terrestrial biodiversity overall. Based on range estimates for >46,000 tree species, our findings show that a large proportion of tree species receive limited protection by current PAs and are under substantial human pressure. Improved protection of biodiversity overall would also strongly benefit global tree diversity.
