title: Kaupapa Māori and a new curriculum in Aotearoa/New Zealand

authors: Chalmers, Lex

subjects: curriculum review

abstract: While geographical education is our focus in this paper, the broader colonial history of education is the backdrop against which we first view the principles of Māori geographies in education. The essay underscores the importance of ‘authenticity’, the participation of local communities and local studies connected to local environments and histories. We use an educational program of the Raglan Area School on Whaingaroa Harbour as an illustrative example. The geographies of Whaingaroa Harbour provide an exemplary context for programs in geographical education and we suggest that the new curriculum in both English and Te Reo Māori (Māori language) can enhance the movement towards bi-cultural education in Aotearoa/New Zealand. Our argument is that the 2007 curriculum creates the opportunity; the impediments lie in providing appropriate resources and developing community support for the delivery of the bicultural educational approaches. is an important issue in debates about educational policy and implementing a new curriculum in Aotearoa/New Zealand. This paper explores how the development of the 2007 curriculum in Aotearoa/New Zealand attempted to address curriculum, teaching and learning options for Māori. Māori are a significant national community with needs and aspirations in education. Māori have tangata whenua status in Aotearoa/New Zealand, where this term acknowledges the arrival and settlement of migrant people of the Pacific centuries prior to significant European colonization in the 19th Century. While progress has been made in Māori education since the significant Treaty of Waitangi Act in 1975, we wish to explore the potential of Kaupapa Māori (Māori practice) in the development of a new curriculum, Te Marautanga o Aotearoa.

title: When loanwords are not lone words: Using networks and hypergraphs to explore Māori loanwords in New Zealand English

authors: Trye, David

abstract: Networks are being used to model an increasingly diverse range of realworld phenomena. This paper introduces an exploratory approach to studying loanwords in relation to one another, using networks of co-occurrence. While traditional studies treat individual loanwords as discrete items, we show that insights can be gained by focusing on the various loanwords that co-occur within each text in a corpus, especially when leveraging the notion of a hypergraph. Our research involves a case-study of New Zealand English (NZE), which borrows Indigenous Māori words on a large scale. We use a topic-constrained corpus to show that: (i) Māori loanword types tend not to occur by themselves in a text; (ii) infrequent loanwords are nearly always accompanied by frequent loanwords; and (iii) it is not uncommon for texts to contain a mixture of listed and unlisted loanwords, suggesting that NZE is still riding a wave of borrowing importation from Māori.

title: Water relations and carbon dioxide exchange of epiphytic lichens in the Namib fog desert

authors: Lange, Otto L.

subjects: dew

abstract: Although there is only negligible rainfall, frequent nocturnal fog, dew and high air humidity support a luxurious lichen vegetation in the coastal zone of the central NamibDesert (Namibia). In earlier publications, we have studied ecophysiological performance of a series of epilithic and terrestrial lichens. Here, we have extended this work to three epiphytic species (Heterodermia namaquana, Ramalina lacera, and Xanthoria turbinata) that inhabit the sparse perennial shrubs growing in this area. Our intention, monitoring lichen CO₂ exchange, their waterrelations and microclimate conditions, was to determine the functional mechanisms that allow these epiphytes to exist under the special conditions of a fogdesert. Measurements were conducted mainly during the spring season.
The epiphyticlichens showed response patterns very similar to the epilithic and epigaeic species at the same site. Their metabolism was activated through moistening by dew and/or fog during the night and, in the very early morning, they exhibited the typical brief peak of net photosynthesis (NP) between sunrise and desiccation. The thalli were almost completely dry for the remainder of the day. Average duration of the positive NP during the morning peak was about 3 h. Dew condensation, alone, resulted in activation that provided 58–63% of integrated carbon income (ΣNP) as compared to fog (plus dew). In the late afternoon, there was a tendency for hydration to increase again, due to water vapour uptake at higher air humidity, and this allowed on some days a brief additional period of very low rates of photosynthesis shortly before sunset.
Light response of photosynthesis showed “sun-plant” characteristics with saturation around 1000 μmol m⁻² s⁻¹ photosynthetically active photon flux density (PPFD). Light compensation point (LCP) of CO2exchange after sunrise was highly dependent on actual water content (WC) for X. turbinata: at low hydration it was ca. 10 μmol m⁻² s⁻¹ PPFD whilst, at high WC, it was almost 80 μmol m⁻² s⁻¹ PPFD. In contrast, LCP of R. lacera was almost independent of WC. This phenomenon was probably due to differences in thallus structure.
Maximal attained NP and daily ΣNP both showed a saturation-type response to previous maximal nocturnal WC. Neither parameter was increased substantially when higher maximal thallus WCs were produced by experimental moistening in the night. All three species, despite their different morphologies, performed optimally at the highest nocturnal moistening achieved by natural fog and were not able to make use of higher hydration.
The three studied epiphytes were similar in their chlorophyll-related rates of NP. Due to lower chlorophyll content, dry weight and carbon-related NP of X. turbinata was only about one-third of that of the other two species. The average carbon income on days with fog and/or dew hydration during the spring season amounted to 2.4 and 2.1 mgC (gC)⁻¹ day⁻¹ (related to thallus carbon content) for H. namaquana and R. lacera, respectively. This primary production was of similar magnitude to those found for the terrestrial species at the same site.
