title: Comparative ecophysiology of three Placopsis species, pioneer lichens in recently exposed Chilean glacial forelands

authors: Raggio, José

subjects: nitrogen fixation

abstract: Lichen species belonging to the genus Placopsis are early colonisers on snow free moraines of exposed land surfaces in the subantarctic region of Tierra de Fuego, South Chile. The physiological performance of three co-occurring species, P. pycnotheca, (terricolous), and P. perrugosa, and P. stenophylla (both saxicolous) was studied. All, possess green algal photobionts but have cyanobacteria in cephalodia. It was found that there was (i) a strong positive correlation between the acetylene reduction rate (AR) and the maximum photosynthetic rate (Amax), between the N content and the AR rate, and between the N and P contents, and (ii) the relationship between the CO2-exchange rates and the responses obtained in the laboratory reflected the ecology of these three lichens in the field. The results provide new information about the dynamics of some of the fastest growing crustose lichens. We hypothesize that the performance of these three species may have developed as a response to growing in an unstable environment that resulted from frequent glacial fluctuations.

title: Fraternity and Equality

authors: Cupit, Geoffrey

subjects: fraternity

abstract: Is there a connection between the values of fraternity and outcome equality? Is inequality at odds with fraternity? There are reasons to doubt that it is. First, fraternity requires us to want our ‘brothers’ and ‘sisters’ to fare well even when they are already better off than we are and their doing better will increase inequality. Second, fraternity seems not to require equality as a matter of fairness. Fairness requires (a certain) equality, but fraternity does not require fairness.
In examining what fraternity requires I discuss Rawls' suggestion that the difference principle corresponds to a natural meaning of fraternity, arguing that fraternity may be even more tolerant of inequality than the difference principle. Nevertheless, I defend the claim that fraternity and equality are linked, albeit not in such a way as to make inequality inconsistent with fraternity. Fraternity is related to equality since equalizing expresses the connectedness at the core of fraternity; but inequality is consistent with fraternity since there are other ways of expressing that connectedness.

title: Representations of te reo Māori and te ao Māori in a translingual picturebook: How my Koro became a Star

authors: Barbour, Julie Renee

subjects: Indigenous language and culture

abstract: While English is the most commonly used language in Aotearoa New Zealand, it is a multilingual nation with two languages recognised as official: te reo Māori (the Māori language) and New Zealand Sign Language. The English language is dominant in children’s literature published in Aotearoa New Zealand, but since the 1980s there has been an increase in the number of picturebooks featuring two languages, te reo Māori and English. Previous work has explored how representations of te reo Māori and English in pukapuka pikitia reorua (dual language picturebooks) in Aotearoa reflect changing attitudes towards the two languages. In this article, we focus particularly on Brianne Te Paa and Story Hemi-Morehouse’s picturebook How my Koro became a Star. Originally written in te reo Māori, this multi-award winning picturebook is located at the beginning of Matariki, the Māori New Year celebration. In a move away from the linguistic analysis of te reo Māori being ‘borrowed’ by English, we consider how storytellers like Te Paa weave Māori language together with English in a translingual publication, supporting reader comprehension of Māori vocabulary and cultural meanings through embedded illustrations and explanations, inviting the curious reader to learn beyond the story.
