title: Coastal evolution of the Rangitāiki Plains, Bay of Plenty, Aotearoa-New Zealand

authors: Rackham, Bailey

subjects: Rangitaiki Plains

abstract: The Rangitāiki Plains is a tectonically active alluvial plain in the Eastern Bay of Plenty, New Zealand. Throughout the mid-late Holocene (8 ka to present), the Rangitāiki Plains have undergone substantial geomorphological change, with the coastline prograding approximately 10 km over the past 6.5 ka, leaving relic shoreline features known as beach ridges. Previous studies of the Rangitāiki Plains have utilised tephrochronology and radiocarbon dating to determine the ages of several palaeoshorelines. These dates provided minimum ages for beach ridges and resulted in aging constraints; furthermore, limited textural and geochemical characterisation of beach ridges has hampered understanding of sediment provenance and reworking changes. Addressing these research gaps is important as this knowledge is especially relevant in coastal management, modern climate change, and increasing anthropogenic impacts on the coastline.  

Optically Stimulated Luminescence (OSL) dating on the Rangitāiki Plains produced older beach ridge ages than those derived via tephrochronology. OSL dating also showed that beach ridge ages coincided with volcanic eruption events. The OSL progradation rates extend to much older time frames than those based on tephrochronology, starting at 7.6 ka rather than 5.5 ka. New data concludes a prominent progradation peak up to 43.03 m yr⁻¹ between 5.202±0.368 ka and 5.187±0.447 ka, around the time of the Whakatāne eruption. By 4 ka, progradation had slowed to only 1.14 m yr⁻¹, suggesting that longshore drift occurred earlier than previously calculated (2 ka), or that progradation slowed before longshore drift commenced. XRF and XRD analysis of sediments from Rangitāiki Plains confirms that beach ridge sediments comprise of intermediate igneous sediments that have been tephra fingerprinted to the Taupō Volcanic Zone.

title: Rethinking XML-enabled agile supply chains

authors: Ahn, Hyung Jun

subjects: agile supply chain

abstract: This paper critically discusses the use of Extensible Markup Language (XML) for agile supply chains and proposes practical guidelines and future research directions for the field. XML has been identified by many as a prominent technology for enabling electronic supply chain integration, but the adoption of it in the industry has been rather slow and limited. This paper discusses the factors that enable agility in supply chains, and explains why XML is the best candidate for facilitating such factors. Then the major XML-based integration initiatives such as ebXML, RosettaNet, and Web Services are diagnosed in terms of their pros and cons for supply chain agility, as well as the reasons for their slow diffusion. Based on the discussion, this paper proposes that: the integration efforts need to first focus on the industries that need agility; stringent business process standards are necessary; and implementation should be made much easier and more affordable for small and medium enterprises (SMEs). Further research issues are also suggested based on the discussion.

title: Bizarre thoughts, magical ideations, and voices from the unconscious: Exploring issues of anomalous experience

authors: Tamatea, Armon J.

subjects: Maori

abstract: This project was initially concerned with the clinical interpretations of ‘bizarre’ or
‘magical’ ideations (i.e., statements considered to have little or no validity in our
predominant western culture). The first study explored clinical assessment issues
of who determines the validity of expressed beliefs and what kinds of criteria such
decisions are based on in the mental health field. The present study examined a
particular type of magical ideation, an auditory phenomenon involving claims that
forward spoken conversation contains hidden backwards speech embedded in the
vocal sounds. Thirty-two participants were invited to listen to various audio
samples of the alleged phenomenon and provide interpretations of what was heard.
Participants were assigned to four groups, each differing in the level of pre-emptive
information. A comparative measure revealed that priming and suggestion could
not be dismissed as alternative explanations of the reported effects. Clinical and
social implications will be discussed.
