Indonesian inquiry: A narrative of biocultural teaching on Sulawesi Utara

British Educational Research Journal, EarlyView.
Abstract Using phenomenology, narrative inquiry and autoethnographic approaches, this study analyses a program of faculty development conducted alongside the delivery of an international field school. Through this study, we explore the value and benefits of inter‐cultural field programming and how these might serve to complement or to redress ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Fracturing control method for deep volcanic rock gas reservoirs in Daqing exploration area

Petroleum Exploration and Development, 2009
Pores, cavities and fractures are well-developed in deep volcanic reservoirs. The simultaneous break and extension of multi-fractures in treatment caused early stage sand-block, low fracturing success ratios, small treatment scales, and bad stimulation ...

Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction

ChemistryEurope, EarlyView.
This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.

Volcanic Facies From Probabilistic Multi‐Physics Characterization of an Andesite Island Volcano, Whakaari/White Island, New Zealand

Geochemistry, Geophysics, Geosystems
Collapse of hydrothermally weakened rock on the flanks of volcanic islands is a recognized cause of tsunamis generated by volcanoes. Here we use a multiphysics clustering method to derive a volcanic facies model for Whakaari/White Island, an andesite arc
