Research aiming at generating effective contributions to sustainable development faces particular complexity related challenges.
This article proposes an analytical framework disentangling and structuring complexity issues with which research for sustainable
development is confronted. Based on theoretical conceptions from fields like policy sciences and transdisciplinary research
as well as on an in-depth analysis of the concept of sustainable development, three meta-perspectives on research for sustainable
development are introduced and elaborated. The first perspective focuses on notions of sustainable development, sorting out
the problem of unclear or ambiguous interpretations of the general sustainability objectives in specific contexts. The second
perspective introduces a broad conception of the policy process representing the way societal change towards sustainable development
is brought about. It supports identifying those academic and non-academic actors and stakeholders that are relevant for coming
up with effective knowledge contributions. The third perspective identifies different forms of knowledge that are needed to
tackle sustainability problems as well as the significance of their mutual interrelations. How the framework perspectives
support reflecting on the fundamental complexity issues research for sustainable development is confronted with is illustrated
using a case example from natural scientific research in the field of land use. We argue that meeting the complexity inherent
in the concept of sustainable development requires joint learning in policy processes, working out shared visions being in
line with the core objectives of sustainable development and generating knowledge about empirical, normative and pragmatic
aspects. 相似文献

Fossilization in amber is unique in preserving specimens with microscopic fidelity; however, arthropod inclusions are rarely
examined beyond the exoskeleton as this requires destructive sampling when traditional techniques are used. We report the
first complete, digital 3D, non-destructive reconstruction of the anatomy of an insect fossil, a specimen of †Mengea tertiaria embedded in a 42-Ma Baltic amber. This was made possible using Synchrotron μ-CT. The species belongs to the stem group of
the phylogenetically enigmatic and extremely specialized Strepsiptera. Most internal structures of the fossil are preserved,
but small parts of the lumen had decayed due to incomplete infiltration of the resin. Data on internal organs provided additional
information for resolving phylogenetic relationships. A sister group relationship between †Mengea and all extant lineages of the group was confirmed with characters previously not accessible. The newly gained information
also yielded some insights in the biology of †Mengea and the early evolutionary history of Strepsiptera. The technique has a tremendous potential for a more accurate interpretation
of diverse fossil arthropods preserved in ambers from 130 Ma to the present. 相似文献
