title: Visualising present and past: a meter with a flexible pointer

authors: Monigatti, Paul

subjects: computer science

abstract: Meters and gauges based on analogue pointers provide a convenient way to visualise single dimensional data streams, such as speed, voltage, altitude, or fuel level. However, often a small amount of historical information helps to understand the data at a glance, and reduces the need for constant vigilance; is the parameter relatively stable; is it increasing or decreasing? Have there been any transients in the past minute? What trends are present?

This paper describes a virtual analogue meter with a flexible pointer that shows both the instantaneous value at the tip and bends to a brief interval of history along its length. The meter has been developed in the context of monitoring the electricity grid, but has many other potential applications.

title: Invasion, genetic variation and species identity of the calanoid copepod Sinodiaptomus valkanovi

authors: Makino, Wataru

subjects: biological invasion

abstract: 1. Although Sinodiaptomus valkanovi [sensu Ueda & Ohtsuka (Hydrobiologia, 379, 1998, 159)] is one of the most common freshwater calanoid copepods in Japan, it was originally described from specimens collected in Sofia, Bulgaria, as a subspecies of S. sarsi. This original description raises two issues requiring further investigation. One is whether or not S. valkanovi should be differentiated from S. sarsi at a species level, and the other is whether or not records of S. valkanovi from outside of Japan are the result of biological invasions.
2. We examined the gene flow between S. valkanovi and S. sarsi in Japan, using nuclear DNA (the ribosomal internal transcribed spacers 1 and 2 plus the intervening 5.8S ribosomal DNA subunit) sequence to clarify if these two taxa are separable at a species level. We also investigated the population genetic structure of S. valkanovi in Japan, using the mitochondrial cytochrome c oxidase subunit I (mtCOI) gene, and subsequently of two recently discovered New Zealand populations, to elucidate the origin and colonisation/invasion history of this taxon.
3. In total, 43 and three Japanese populations of S. valkanovi and S. sarsi, respectively, were analysed. These two taxa did not occur together in any of the localities. Nuclear DNA analysis did not provide any evidence of gene flow between them, and the inter-taxon variability of mtCOI was high, corroborating the conclusion of Ueda & Ohtsuka based on morphological characteristics that S. valkanovi and S. sarsi should be differentiated at the species level.
4. In Japan S. valkanovi populations are segregated into two areas, around the Seto Inland Sea (SIS) and northeastern (NE) area. A distinct contrast in the genetic diversity was observed between the areas; five mtCOI haplotypes were recovered from the NE area while 38 were observed in the SIS area, despite a similar geographical range and number of individuals analysed in both areas. Furthermore, S. valkanovi in the SIS area possessed a mixture of both ancestral and derived haplotypes, while those in the NE area mostly consisted of derived haplotypes. These results suggest that the NE populations were founded recently by a limited numbers of individuals from SIS populations.
5. All specimens of S. valkanovi from New Zealand possessed one specific mtCOI haplotype. In Japan, this haplotype was found only in the NE area, suggesting the origin of New Zealand S. valkanovi. It is likely that this copepod has on several occasions invaded areas outside of Japan, one of which was associated with the original description of this taxon in Bulgaria.

title: Kia rehe te matau, kia rehe te maui

authors: Winiata, Te Whatanui Huia

subjects: Taiaha, Maori business, maori development

abstract: The theory of applying successful military strategy to the world of business is not a new concept.  The connection between these two environments has often been explored, and works by Sun Tzu and others promote the connection between the battlefield and the boardroom.  The cut and thrust of the business realm is often likened to combat, and the guiding principles and beliefs that influence Generals and Field Commanders are in many ways identical to those of executives and Chief Executive Officers.

This thesis is interested in exploring the interconnectedness between battle and business from a Māori perspective.  In particular, this study explores the link between the Māori weapon known as the taiaha, and Māori business, in the belief that the lessons learnt from the various taiaha schools can be transferred to Māori business.  Likewise, the beliefs, principles and philosophies that are instilled within warriors while training with the taiaha have a valid place within Māori business, and when applied to the Māori business arena, have beneficial outcomes for those involved.

This study highlights fundamental taiaha principles that are applicable to the Māori business world.  These beliefs have been identified by a number of taiaha experts as well as successful Māori business operators.  The long term purpose of this thesis is to support Māori entering into business, by highlighting traditional values that are taught through the medium of taiaha, and showing how they can be applied to business.
