title: Defining and deploying the concept of 'precarious employment': Valuable idea or empirical fallacy?

authors: East, Dayna Erin

abstract: The definition.

We define precarious employment as work for remuneration that is deemed more-or-less precarious based on three indicators explicitly related to the regularity of the employment contract:

- the job can be terminated with little or no prior notice from the employer
- working hours and/or earnings are uncertain/irregular
- a contract for ongoing employment is non-existent.

Across different typologies and definitions, job insecurity is the core/essential element (or common denominator) of precarious employment.

Precarious employment, so defined, will be experienced differently by heterogeneous workers who possess different buffers against its insecurity.

Regardless of the subjective experience, workers can objectively be said to be (or not) in precarious employment.

title: Food webs in forest and pasture streams in the Waikato region, New Zealand:  A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents.

authors: Hicks, Brendan J.

subjects: stable isotopes

abstract: Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material (conditioned leaf litter and terrestrial invertebrates). Autotrophs in forest streams were not a significant C source for the food webs. However, the C source of food webs in the unshaded pasture streams appeared to be a mixture of allochthonous and autochthonous material. Conditioned leaf litter appeared to contribute to the pasture stream food webs, and the d13C and d15N of some samples of epilithic diatoms indicated their consumption by invertebrates in pasture streams. Fish ate a wide range of aquatic invertebrates; longfinned eels (Anguilla dieffenbachiai) and banded kokopu (Galaxias fasciatus) also had a large proportion of terrestrial invertebrates in their diet. Filamentous green algae were found only at pasture sites, where they were sometimes abundant. The wide range of d13C values of filamentous green algae (-18.8 to -29.7[[perthousand]]) complicated understanding of their role in the stream food webs. The d13C values of Cladophora were related to water velocity, with more 13C-enriched values in pools than in runs (-23.2[[perthousand]] in pools, mean velocity 0.12 m s-1; -28.1[[perthousand]] in runs, mean velocity 0.24 m s-1). Crayfish and the gastropod mollusc Potamopyrgus appeared to be the only invertebrates to eat filamentous green algae.

title: The relevance of discourse analysis to the teaching and learning of te reo Māori: A text-centred example

authors: Greensill, Hine-iti-moana

subjects: Māori language

abstract: In this paper, I analyse a single text written in te reo Māori in terms of two different approaches derived from discourse analysis (discourse macro-patterning and discourse relations and their signalling) in order to demonstrate the importance of deriving a discourse-centred methodology for teaching learners of Māori what is involved in interpreting and creating coherent discourses.
