title: Molecular ecology techniques for the study of aerobic Methanotrophs

authors: McDonald, Ian R.

abstract: Methane oxidation can occur in both aerobic and anaerobic environments; however, these are completely different processes involving different groups of prokaryotes. Aerobic methane oxidation is carried out by aerobic methanotrophs, and anaerobic methane oxidizers, discovered recently, thrive under anaerobic conditions and use sulfate or nitrate as electron donors for methane oxidation. This review will focus on the aerobic oxidation of methane.

title: Does respondent perception of the status quo matter in non-market valuation with choice experiments? An application to New Zealand freshwater streams

authors: Marsh, Dan

subjects: choice experiments

abstract: In environmental valuation studies with stated preference methods, researchers often provide descriptions of status quo conditions which may differ from those perceived by respondents. Ignoring this difference in utility baselines may affect the magnitude of utility changes and hence bias the implied estimates of benefits from the proposed environmental policies. We investigate this issue using data from a choice experiment on a community’s willingness to pay for water quality improvements in streams. More than 60 percent of respondents perceived the description of the quality of water in streams to be better than the one we provided in our scenario. Our results show that respondents who could provide details of their perception of the status quo displayed stronger preferences for water quality improvements - hence a higher marginal willingness to pay - than their counterparts. Respondents who opted for their own status quo description displayed a higher inclination to remain in the status quo, while their counterparts displayed the contrary. We argue this might be linked to the amount of knowledge each group displayed about the status quo: a kind of reluctance to leave what one knows well.

title: Typographic design in Māori-English bilingual picturebooks: some educational implications

authors: Vanderschantz, Nicholas

subjects: Te Reo Māori

abstract: The role of bilingual picturebooks in language learning has been explored recently by a number of authors who show their potential in normalising multilingualism (Naqvi, Thorne, Pfitscher, Nordstokke & McKeough, 2013; Zaidi, 2020), raising metalinguistic awareness and engaging parents (Sneddon, 2009), as well as raising language awareness (Kleker, Short & Daly, 2021). Hadaway and Young (2013) suggest bilingual picturebooks have a particular role to play in supporting the revitalisation of Indigenous languages. In New Zealand, the number of MāoriEnglish bilingual picturebooks is increasing, but there is very little, if any, research concerning their design or their use in educational settings. The design of bilingual picturebooks, as reflected in their linguistic landscape, has an important role to play in their pedagogical use (Daly, 2016; 2017), and in this article, we explore the typographic design of five bilingual Māori-English picturebooks with respect to the elements of typeface, type size, type colour and page layout. We discuss the design and audience implications of these factors for educational settings.
