title: Nematodes in a polar desert reveal the relative role of biotic interactions in the coexistence of soil animals.

authors: Caruso, Tancredi

abstract: Abiotic factors are major determinants of soil animal distributions and their dominant role is pronounced in extreme ecosystems, with biotic interactions seemingly playing a minor role. We modelled co-occurrence and distribution of the three nematode species that dominate the soil food web of the McMurdo Dry Valleys (Antarctica). Abiotic factors, other biotic groups, and autocorrelation all contributed to structuring nematode species distributions. However, after removing their effects, we found that the presence of the most abundant nematode species greatly, and negatively, affected the probability of detecting one of the other two species. We observed similar patterns in relative abundances for two out of three pairs of species. Harsh abiotic conditions alone are insufficient to explain contemporary nematode distributions whereas the role of negative biotic interactions has been largely underestimated in soil. The future challenge is to understand how the effects of global change on biotic interactions will alter species coexistence.

title: Two novels by Herman Hesse: Demian and Der Steppenwolf

authors: Douglas, Donald Brett

abstract: As the section of this study devoted to Der Steppenwolf will demonstrate , much secondary literature treating Hermann Hesse has confined itself to an uncritical, frequently adulatory discussion of his oeuvre , many articles and even books consisting merely in a recapitulation or paraphrase of his various works. Seymour Flaxman is an exemplary representative of this tendency.
A contrasting trend is, however, extant. As the section on Demian will clarify, Hugo Ball and Colin Wilson are two critics not as willing as many scholars to accept Hesse at face value. Yet their critiques are not related in detail to textual phenomena, stemming more from subjective criteria and feelings.

title: Formulaic Discourse Patterning in Mōteatea

authors: Roa, Te Raukura o Te Rangimarie

subjects: mōteatea

abstract: Oral formulaic composition, which involves the use of communally owned formulae of various kinds, is a common feature of verbal arts produced in many different languages. It is particularly associated with pre-literate cultures and tends to be gradually replaced by more individualistic verbal art forms when societies become literate. There are very few publications in which the analysis of mōteatea (Māori laments) is linked explicitly to oral formulaic theory. Nevertheless, there is, I believe, sufficient evidence in published sources to indicate that traditional mōteatea (defined here as mōteatea that are not fundamentally influenced by European cultural beliefs and practices) exhibit evidence of regularly recurring, conventional themes (such as death, separation, loss and travel) and motifs (such as the setting sun, the presence of rain or mist and sleeplessness).  There is, however, considerably less evidence that traditional mōteatea make extensive use of verbal formulae, that is, of the same or very similar groups of words derived from a common store of poetic resources. Although there are references in the literature to the conventionalized use of language in mōteatea, and although it has been claimed that there are at least some commonly recurring verbal expressions, this is by no means evidence of reliance on a common stock of verbal formulae. Indeed, no attempt has hitherto been made to define precisely what might be meant by the term 'oral formula' in the context of compositions in te reo Māori, something that is clearly required in view, in particular, of the fact that the phrasal structure of the language means that certain groupings (e.g. i te X; ki te X) are very likely to occur in certain contexts irrespective of genre. Furthermore, in the literature on oral formulaic composition, oral formulae are generally linked to particular metrical conditions and there is, it is argued here, no convincing empirically-based evidence that mōteatea conform to any common metrical structure or structures (see Chapters 2 and 4).

In the context of a critical review of selected literature on oral formulaic theory (Chapter 2) and mōteatea (Chapter 3), this thesis sets out to test the hypothesis that traditional mōteatea were composed, in whole or in large part, from a common stock of oral formulae. The conclusion, based on analysis of a selection of mōteatea included in Ngā mōteatea, a collection initially established by Sir Apirana Ngata, is that this hypothesis must be rejected (Chapter 4). However, a model derived from a review of selected literature on discourse structure (Chapter 5) was also applied to the analysis of a sample of these mōteatea (Chapter 6). On the basis of this analysis, it is concluded that they exhibit one of two very similar discourse prototypes, each of which involves a particular combination of discourse elements. What distinguishes the two prototypes is the fact that only one of them is characterized by the inclusion of hortatory sections in which the poet urges one or more of the protagonists to undergo one or more steps or stages required to achieve a particular outcome, such as entry into the spirit world or vengeance for death and/ or humiliation.
