MODELING SPATIAL DEPENDENCE AND SPATIAL HETEROGENEITY IN COUNTY YIELD FORECASTING MODELS

The implications of ignoring potential spatial dependence in county-level yield data are discussed. Spatial dependence in a county-level yield data set is identified and methods for correcting the dependence via spatial weighting matrices and generalized least squares regression are performed. The paper also examines how the spatial dependence declines as the distance between observations increases.Productivity Analysis, Research Methods/ Statistical Methods,

The prose poem as Igel: a reading of fragmentation and closure in prose poetry

This paper takes up Nikki Santilli’s lament about the scarcity of scholarship on the prose poem in English to analyse two key features of prose poetry: fragmentation and closure. This paper argues that the prose poem’s visual containment within the paragraph form promises a complete narrative while simultaneously subverting this visual cue by offering, instead, gaps and spaces. Such apertures render the prose poem a largely fragmentary form that relies on metonymic metamorphoses to connect to a larger, unnamed frame of reference. In this way, the prose poem is both complete and yet searching for completeness, closed and lacking closure.The prose poem’s reaching outwards to embrace a larger, absent whole connects this literary form to Friedrich Schlegel’s ‘Athenaeum Fragment 206’ and to the Romantic critical fragment more generally. ‘Athenaeum Fragment 206’ has provided this paper with its title, as a metaphorical reading of Schlegel’s igel, or hedgehog, as fragment ‘implies the existence of [a form that suggests] what is outside itself’ (Rosen 1995: 48). The final section of this paper, analyses two prose poems from the University of Canberra’s International Poetry Studies Institute’s Prose Poetry Project. These works by Jen Webb and Carrie Etter are read for their appeal to metonymy in their exploration of time passing and ultimately, death. They demonstrate that prose poetry is both fragmented and open ended in ways very different from lineated poems

Broken forms: Prose poetry as hybridised genre in Australia

Traditional literary genres, such as the novel, lyric poetry and short fiction have been at the centre of Australian literary practice since European colonisation. Increasingly, however, Australian creative writers are making use of narrative and poetic forms that do not sit comfortably within accepted genre classifications. They are doing so partly in order to respond to their encounters with fragmentation and multivalency and to register the disparate, the diverse and the ‘broken’ in postmodernity. It is possible that contemporary culture requires such literary forms in order to speak truthfully about the crises at the heart of modernity centred on identity, the interpenetration and mixing of cultures, and the need to find authentic ways of speaking. One form that crosses and destabilises genres is the prose poem. Prose poetry enables intimate lyrical gestures to be joined to a limited narrative discursiveness and signals that the ‘prosaic’ and the ‘poetic’ are frequently bound together. In doing so, it challenges assumptions about what may be ‘said’ in writing, and whether much of human experience in the twenty-first century may best be expressed through the creation of ‘in-between’ literary spaces (and associated tropes of absence and indeterminacy), rather than through traditional generic models. Using examples from contemporary Australian prose poets, this paper demonstrates the way in which Australian prose poetry prioritises spaces of uncertainty and anxiety to rework the British and American canon and make its own identity

Discordance between cosmogenic nuclide concentrations in amalgamated sands and individual fluvial pebbles in an arid zone catchment

Based on cosmogenic 10Be and 26Al analyses in 15 individual detrital quartz pebbles (16–21 mm) and cosmogenic 10Be in amalgamated medium sand (0.25–0.50 mm), all collected from the outlet of the upper Gaub River catchment in Namibia, quartz pebbles yield a substantially lower average denudation rate than those yielded by the amalgamated sand sample. 10Be and 26Al concentrations in the 15 individual pebbles span nearly two orders of magnitude (0.22 ± 0.01 to 20.74 ± 0.52 × 10610Be atoms g−1 and 1.35 ± 0.09 to 72.76 ± 2.04 × 10626Al atoms g−1, respectively) and yield average denudation rates of ∼0.7 m Myr−1 (10Be) and ∼0.9 m Myr−1 (26Al). In contrast, the amalgamated sand yields an average 10Be concentration of 0.77 ± 0.03 × 106 atoms g−1, and an associated mean denudation rate of 9.6 ± 1.1 m Myr−1, an order of magnitude greater than the rates obtained for the amalgamated pebbles. The inconsistency between the 10Be and 26Al in the pebbles and the 10Be in the amalgamated sand is likely due to the combined effect of differential sediment sourcing and longer sediment transport times for the pebbles compared to the sand-sized grains. The amalgamated sands leaving the catchment are an aggregate of grains originating from all quartz-bearing rocks in all parts of the catchment. Thus, the cosmogenic nuclide inventories of these sands record the overall average lowering rate of the landscape. The pebbles originate from quartz vein outcrops throughout the catchment, and the episodic erosion of the latter means that the pebbles will have higher nuclide inventories than the surrounding bedrock and soil, and therefore also higher than the amalgamated sand grains. The order-of-magnitude grain size bias observed in the Gaub has important implications for using cosmogenic nuclide abundances in depositional surfaces because in arid environments, akin to our study catchment, pebble-sized clasts yield substantially underestimated palaeo-denudation rates. Our results highlight the importance of carefully considering geomorphology and grain size when interpreting cosmogenic nuclide data in depositional surfaces

Testing the Attractiveness and Efficacy of Baits for the Monitoring and Control of the Thief Ant, Solenopsis papuana

Solenopsis papuana is one of the few introduced ant species that have widely infiltrated undisturbed mesic and wet forests in Hawaii. This may be problematic since many endemic Hawaiian insects are limited to mountain forests, and methods for monitoring and controlling S. papuana would be useful. Four non-toxic monitoring baits (corn syrup, SPAM®, peanut butter, and tuna/ corn syrup blend) and five ant pesticide baits (Advion® Fire Ant BaitTM, Amdro® Ant Block®, ExtinguishTM Plus, MaxForce® Complete Brand Granular Insect Bait, and SiestaTM) were tested for attractiveness to S. papuana in choice tests at Lyon Arboretum and Pahole Natural Area Reserve (NAR) on the island of Oahu. Amdro® Ant Block® and SiestaTM were also tested for efficacy against S. papuana in field plots at Pahole NAR. SPAM® and peanut butter were the most attractive monitoring baits at both locations. There were few significant differences in at- tractiveness among the five ant pesticides, but Amdro® Ant Block® attracted the highest or second highest number of ants at both sites, while rankings among the other baits were inconsistent. Amdro® Ant Block® presented in bait stations 2.5 m apart greatly reduced the number of ants at monitoring cards in field plots, by an average of 96% from pre-treatment levels over the course of the 246-day trial. Ant numbers also declined in the SiestaTM plots (by 77%), but more closely mir- rored fluctuations in the untreated control plots. These methods were effective for monitoring and suppressing S. papuana populations in localized natural areas in the Waianae Mountain Range

Equity gaps are attributed to course structure in introductory physics

We add to a growing literature suggesting that demographic grade gaps should be attributed to biases embedded in the courses themselves. Changes in the structure of two different introductory physics classes were made while leaving the topics covered and the level of coverage unchanged. First, a class where conceptual issues were studied before doing any complicated calculations had zero final exam grade gap between students from underrepresented racial/ethnic groups and their peers. Next, four classes that offered students a retake exam each week between the regular bi-weekly exams during the term had zero gender gap in course grades. Our analysis indicates that demographic grade gaps can be attributed to the course structure (a Course Deficit Model) rather than to student preparation (a Student Deficit Model).Comment: 10 pages, 3 figure

Poetry co-translation and an attentive cosmopolitanism: internationalising contemporary Japanese poetry

The majority of Japanese poetry currently reaches a limited readership outside of Japan. As a result, many contemporary Japanese poets are searching for ways to have their poems translated into English and published in English-language journals. Achieving satisfactory translation results, however, is considerably more complicated than switching words from one language into another and scholarship on the subject of translating Japanese poetry is often vexed. This scholarship frequently traverses much of the same ground as the debate about Japanese prose translation where, depending on their approach, translators may be labelled ‘literalists’ or ‘libertines’. This paper argues that co-translating Japanese poetry may be as much about sharing ideas and ideologies as about lineation, cadence or word choice. Co-translating Japanese poetry has the power to build cross-cultural understandings and to explore and promote ways of understanding Japanese identity. We argue that while translation is often undertaken by the translators in their country of residence, the experience of genius loci and undertaking co-translation in situ may best accommodate such a cross-cultural synergy.This paper draws on our collective experiences in a series of translation workshops at Meiji University. These were organised by Rina Kikuchi, a literary scholar and translator from Japan. Among other Australian poets and scholars, Paul Hetherington and Cassandra Atherton were paired with Japanese poets for co-translation purposes. They co-translated Japanese poetry into English and had their own poems translated into Japanese with the assistance of Kikuchi who acted as the lynchpin for the workshops. The experience was celebrated in a series of poetry readings in Tokyo and Nara. Significantly, although neither Hetherington nor Atherton is fluent in Japanese, they found the process of co-translation to include what one may call an attentive cosmopolitanism, incorporating respect and understanding for different cultural assumptions and poetic ideas.
