title: The soil geochemistry in the Beardmore Glacier Region, Antarctica: Implications for terrestrial ecosystem history

authors: Lyons, W.B.

abstract: Although most models suggest continental Antarctica was covered by ice during the Last Glacial Maximum (LGM) it has been speculated that endemic species of soil invertebrates could have survived the Pleistocene at high elevation habitats protruding above the ice sheets. We analyzed a series of soil samples from different elevations at three locations along the Beardmore Glacier in the Transantarctic Mountains (in order of increasing elevation): Ebony Ridge (ER), Cloudmaker (CM), and Meyer Desert (MD). Geochemical analyses show the MD soils, which were exposed during the LGM, were the least weathered compared to lower elevations, and also had the highest total dissolved solids (TDS). MD soils are dominated by nitrate salts (NO₃/Cl ratios >10) that can be observed in SEM images. High δ¹⁷O and δ¹⁸O values of the nitrate indicate that its source is solely of atmospheric origin. It is suggested that nitrate concentrations in the soil may be utilized to determine a relative “wetting age” to better assess invertebrate habitat suitability. The highest elevation sites at MD have been exposed and accumulating salts for the longest times, and because of the salt accumulations, they were not suitable as invertebrate refugia during the LGM.

title: Supply chain integration: an international comparison of maturity

authors: Childerhouse, Paul

subjects: supply chain integration

abstract: Purpose – The purpose of this paper is to examine the uptake of supply chain integration (SCI) principles internationally and the resultant integration maturity.
Design/methodology/approach – A rigorous supply chain diagnostics methodology called the Quick Scan is used to assess the integration maturity of 72 value streams located in New Zealand, Thailand and the UK.
Findings – The majority of the organisations studied are struggling to turn the SCI concept into reality. Supply chains on average are poorly integrated. However, there exist a handful of exemplar cases that provide guidance; levels of integration maturity appear not to differ internationally.
Research limitations/implications – Only three nations are compared, hence the sample is not fully representative of all countries and industries. There is a significant gap between supply chain rhetoric and practice; clear guidance on how to enable effective integration is required. National settings do not appear to affect the extent of application of supply chain management concepts.
Practical implications – SCI is a very difficult undertaking. Indifferent practice is the norm. If organisations can attain even the middle ground of internal integration they will outperform many of their competitors.
Originality/value – The paper presents an international benchmark of SCI maturity involving three triangulated measures of supply chain performance.

title: Ko ētehi waiata tangi o Pare Hauraki

authors: Ngāpō, Korohere

subjects: Waiata tangi

abstract: Inā hiahia ai te tangata kia mōhio ngā momo mōteatea o Pare Hauraki i ngā wā o mua me huri atu rātou ki ngā wāhi kohinga waiata pērā i Ngā Mōteatea a Ngata. Ka mutu kua tuhia tēnei pitopito kōrero hei tautoko atu i te hui waiata tawhito i whakatūria i Te Whare Wānanga o Waikato i te 2008. He tirohanga tēnei tuhinga ki te momo o ngā waiata e rua kāore i āta waiatahia, i āta rangona i runga i ngā marae o Hauraki ā mohoa nei. Ka mutu mā te waihape atu anō ki tētehi waiata i titoa e Pua ki Tawhiti mō tōna tungāne tae noa atu ki te waiata tangi i titoa e Wetea rāua ko Tūkehu, tēnā pea, ka ara ake anō te whakaaro me hoki anō ngā iwi o Pare Hauraki ki te waiata atu anō i ēnei waiata.
