title: Tracking and re-finding printed material using a personal digital library

authors: Hinze, Annika

subjects: computer science

abstract: Most web searches aim to re-find previously known information or documents. Keeping track of one’s digital and printed reading material is known to be a challenging and costly task. We describe the design, implementation and evaluation of our Human-centred workplace (HCW) – a system that supports the tracking of physical document printouts. HCW embeds QR codes in the document printout, stores the documents in a personal Digital Library, and uses cameras in the office to track changes in the document locations. We explored the HCW in three evaluations, using the system over several weeks in an office setting, a user study in a lab environment, and extensive functional tests.

title: A micromorphological study of pedogenic processes in an evolutionary soil sequence formed on Late Quaternary rhyolitic tephra deposits, North Island, New Zealand

authors: Bakker, L.

abstract: The influence of time as a soil forming factor was studied on an evolutionary sequence of five soils (1850 radiocarbo years BP-ca. 120,000 BP) developed in rhyolitic tephra deposits in New Zealand. New micromorphological observations were combined with existing macromorphological, chemical, textural, and clay mineralogical analyses to assess the extent of polygenesis in the soils. The younger soils (1850 BP to ca. 22,600 BP) are characterised by initial weathering and little secondary mineral formation. This status is expressed by abundant pumice fragments and fresh, easily weatherable minerals, as well as a low clay content with an isotropic character. Comminution and neoformation are the main pedological processes. The older soils (ca. 120,000 BP) are characterised by a high degree of alteration of primary minerals, little or no pumice fragments, clay illuviation, gleying, and a high clay content (>80%) consisting of a range of crystalline clay minerals including halloysite, gibbsite, kaolinite, and vermiculite, plus crystalline iron oxides. Evidence of polygenesis can be observed in the micromorphology of the older soils: (1) the range of secondary minerals is the result of the integration and succession of soil-forming processes through time; (2) the accumulatory character of the tephra deposits has resulted in stronger weathering of the lower horizons than upper horizons because of continuous pedogenesis. Such polygenesis in the older soils supports the view that the older the soil, the more polygenetic it is likely to be.

title: Flora + Fauna

authors: Apiata, Hāwea

abstract: Visual poetry featured in 'To feel the earth as one's skin: An anthology of Indigenous visual poetry' published by Poem Atlas, London, UK. This poem depicts a koru or an unfurling native fern formed from the words ngāi tipu, referring to plant life (flora), and a tuna or native eel formed from the words ngāi kīrehe, referring to animal life (fauna). Hand-stenciled lettering. Black ink on paper.
