Stoat trap tunnel location : GIS predictive modelling to identify the best tunnel location : a thesis submitted in fulfillment of the requirements for the degree of Master of Philosophy in Geographic Information Systems in Massey University

Stoats are recognised as one of the biggest threats to New Zealand's threatened species. They are difficult to control because of their biological characteristics. Currently trapping is the most common type of control technique that has a proven success rate. Research studies have shown that some traps catch more stoats than others. However the reason for this is not well documented. The effectiveness of a trap set is difficult to determine because not all trap locations are the same and not all people have the same ability to select the best location for a trap. This study uses GIS to spatially analyse stoat capture data from a control operation on Secretary Island in conjunction with commonly available vegetation, habitat, diet and home range spatial data to see if there are consistent patterns that could be used as variables in a model that would predict the best place to locate a stoat trap tunnel. The model would then be tested against a similar dataset from Resolution Island. The Department of Conservation supplied the stoat capture data from the control operations on both islands. Standard spatial analysis techniques were used to generate surfaces that combined the capture data with the vegetation, habitat, diet and home range surfaces to produce predictive surfaces. The key finding from the research was that it is possible to produce a predictive model, although one was not created because the spatial datasets were not of a high enough resolution to provide conclusive evidence that could be confidently used as a variable in a model. The spatial analysis also indicated that stoats on both islands were caught mainly in the warmer northwestern parts of the islands although the study could not determine why there was a preference for these areas. In rugged terrain like that found on both islands the location of the track network will influence where the majority of stoats will be caught

Throwing our Voices: Ventriloquism as New Media Activism

In the fall of 2010, Chevron released an ad campaign designed to respond to consumer worries about the conduct of oil companies. Each ad depicted “customers” voicing rather nonspecific concerns about oil companies, answered by the “We Agree” slogan and information about something positive the company is doing in particular communities. Just before the campaign’s official roll-out, the anti-corporate activist group known as the Yes Men produced a series of sophisticated parody ads that spoke in more detail about the damage the company has done in specific countries. Designed to be mistaken for the real, the dummy campaign was distributed with a fake press release purporting to be from Chevron. It was indeed picked up by the press, followed by a cascade of confused articles quoting alternately from the company’s real retraction and a subsequent fake retraction. The Yes Men succeeded in temporarily “throwing their voice” into the body of the Chevron corporation, using a savvy form of ventriloquism as a means of directing the public conversation. Although it is normally the powerful (like large corporations) who are heard in public life, often speaking both for themselves and others, the tactic of ventriloquism temporarily reverses that flow. The case study provides a compelling example of a method of capitalizing on the democratic potential of new media, wielding parody and play as a weapon of the crowd

To Not Understand, but Not Misunderstand: Wittgenstein on Shakespeare

Wittgenstein's lack of sympathy for Shakespeare's works has been well noted by George Steiner and Harold Bloom among others. Wittgenstein writes in 1950, for instance: "It seems to me as though his pieces are, as it were, enormous sketches, not paintings; as though they were dashed off by someone who could permit himself anything, so to speak. And I understand how someone may admire this & call it supreme art, but I don't like it." Of course, the animosity of one great mind for another has its own interest. But the interest here is increased by two factors: (1) Wittgenstein's brief but specific critique of Shakespeare's similes, of interest particularly since he identifies his own philosophical strength half-deprecatingly but still seriously as one of crafting beautiful similes; and (2) Wittgenstein's and Shakespeare's shared concern, as revealed in Stanley Cavell's writings, with the human impulse to skepticism. The present paper considers the importance of these two factors in weighing Wittgenstein's judgment. It suggests that Wittgenstein's frequent charge that Shakespeare is "completely unrealistic" is not a misunderstanding of the Bard (Wittgenstein distinguishes his "failure to understand" from others' willingness to misunderstand Shakespeare) but rather an expression of Wittgenstein's anxiety over Shakespeare's wholly original use of language to represent the sound of the raw motives to skepticism

Satire and Dissent: A Theoretical Overview

In an age when Jon Stewart tops lists of most-trusted newscasters and Michael Moore becomes a focus of political campaign analysis, the satiric register has attained renewed and urgent prominence in political discourse. Day focuses on three central contemporary forms: the parodic news show, the satiric documentary, and ironic activism. She highlights their shared objective of circumventing the standard conduits of political information and the highly stage-managed nature of current political discourse. In so doing, she argues, they provide fans with a sense of community and purpose notably lacking from organized politics in the twenty-first century

A meta-analysis of wage-risk estimates of the value of a statistical life

This paper presents the results of a meta-analysis of estimates of the value of statistical life (VOSL). Data on the sample characteristics, data sources and analytical approach used to derive some 60 separate estimates in 17 published papers are used in the analysis. Tests lead us to reject the hypothesis that this sample shows evidence of publication bias. A meta-regression of these estimates provides evidence that VOSL is increasing in income but is invariant with respect to baseline risk. Controlling for aspects of the sample, data sources and analytical approach allows us to derive a best estimate of the VOSL of around $7 million

Shifting the Conversation: Colbert\u27s Super PAC and the measurement of satirical efficacy

Stephen Colbert’s announcement in 2011 that he was starting his own Super PAC oneupped The Colbert Report’s already substantial commitment to boundary muddling. By raising real money, producing commercials, and exploring the nuances of campaign finance regulations, Colbert acted out his critique of current law in tangible form. The novelty of the experiment created anticipation amongst fans and commentators that the project would have a direct effect on attitudes about campaign finance, or that Colbert would veer into clear advocacy work. Indeed, expectations matched the standard assumptions about satire: that efficacy should be gauged by measurable influence on individual opinions. In reality, the PAC’s commercials likely did not influence many outside his existent fan group. However, the project as a whole did work to license journalistic attention and to impact the wider debate about campaign finance. The example demonstrates that the more grandiose expectations of political entertainment are often misdirected, as they are premised on the prospect of instant audience malleability. Rather the most interesting possibilities involve more incremental shifts in the public conversation

China's fiscal stimulus and the recession Australia never had

China's timely and well-targeted two-year fiscal stimulus was particularly effective in stimulating growth in Australia's commodity exports. Using a constructed series of export volumes to China, this paper finds that the post-stimulus GDP growth contribution from export volumes to China is significant. Had growth in export volumes to China been commensurate with pre-stimulus rates, Australia would have experienced three consecutive quarters of negative real GDP growth � a technical recession. China's gradual and uniquely revenue-based unwinding of fiscal stimulus reduces the risk to Australia of an imminent growth slowdown
