Footwear carried by international air travellers arriving in New Zealand is subject to inspection and if necessary cleaning and disinfecting by MAFBNZ quarantine inspectors A study to evaluate the effectiveness of disinfectant treatment was carried out on three different types of footwear (running shoes gumboots and tramping boots) cleaned following observed MAFBNZ procedure (dip) and following a 10 minute soak Two disinfectant treatments (VirkonTM and TriGene AdvanceTM) were compared with a surfactant (polysorbate 80) and water only Soles were swabbed for microbes before and after washing and culturable bacteria and fungi per cm2 were enumerated Disinfectant treatments reduced bacteria numbers by 99 compared with 98 for both water and surfactant treatments VirkonTM was the best treatment for bacteria both with the standard dip and the 10 minute soak but it was not significantly better than the other treatments Soaking also reduced bacterial numbers compared to the dip treatment but not significantly For fungi the two disinfectants surfactant and water yielded similar reductions (97) Soaking reduced fungal numbers compared to the dip treatment but this was not quite significant (P0051)

SummaryLarge differences in new infection rates occurred with half-udder milking machines in which one half of the cluster operated substantially free from vacuum fluctuations while the other half was subjected to various combinations of different types of fluctuation in vacuum. To increase the rate of new infection all teats were contaminated before and after each milking by immersion in a suspension of Streptococcus agalactiae and Str. dysgalactiae. A series of short-duration trials indicated that neither irregular nor cyclic fluctuations in vacuum acting alone were able to increase new infection rate. However, either the Nyhan and Cowhig irregular fluctuation, or a variant of it in combination with cyclic fluctuations in vacuum, was able to do so under the particular experimental conditions used.

<p>The Man from Nowhere & Other Prose by James McNeish (1991), Berlin Diary by Cilla McQueen (1990), To Each His Own by Philip Temple (1999), and Phone Home Berlin: Collected Non-Fiction by Nigel Cox (2007) are all texts written by New Zealand writers who either visited or lived in Berlin before and after the fall of the Berlin Wall in 1989. Their texts chronicle their experiences in Berlin and capture their observations of and reflections on the city, its people and their place as New Zealand writers in Berlin. This thesis discusses the texts they wrote while in Berlin, focussing particularly on the images of war, walls and the idea of ‘antipodean naivety’. My introductory chapter provides a brief history of New Zealand writers in Berlin. The chapter addresses key historical events which took place in Berlin and how they gave rise to artistic and cultural initiatives, providing the opportunity for McNeish, McQueen and Temple to be in the city. In the second chapter, I consider the images of war found in the writers’ texts. McNeish, McQueen and Temple focus particularly on Berlin’s Second World War history and to a lesser extent on the Cold War. I examine the reasons why they focus so heavily on this part of Berlin’s history, especially when the city has a much longer and broader military history that is ignored by the writers when they address issues of war and conflict in their texts. My third chapter addresses images of walls. For the artists and writers resident in Berlin before the fall of the Berlin Wall, the Berlin Wall is a prominent feature in their texts. But as foreigners to the city and country, they encounter other ‘walls’ such as language and cultural barriers. These metaphorical boundaries are examined further in my fourth chapter which discusses the idea of ‘antipodean naivety’. I apply Mary Louise Pratt’s theory of the ‘contact zone’ in reverse to the experiences of McNeish, McQueen and Temple in Berlin. In my fifth and final chapter I contrast the work of Nigel Cox who was in Berlin ten years after the fall of the Berlin Wall and for a different purpose. Perhaps surprisingly Cox nevertheless responds to Berlin in similar ways to the other New Zealanders. I argue that as New Zealanders these writers come to Berlin from a small country on the other side of the world with a less grandiose history to a country they think they know. In reality, the way the writers interpret their surroundings and the things on which they focus in their texts - almost always Berlin’s twentieth century history - illustrates how little they know about the city, but also suggests how unsettling the experience of the contact zone is, especially when it is such a historically and ideologically-loaded place, and how it makes them aware of their place of origin and their own naiveties and anxieties.</p>

Ti-6A-l4V alloy is widely used in implants and prosthesis applications. Although machining is a fast and economical process, the roughness generated can compromise corrosion resistance. Thus, the goal of this study was to overcome this limitation using thermal oxidation in machined surfaces. Samples with polished surfaces were used for comparison purposes. Two sets of machining parameters were used to generate different roughness, property evaluated in polished and machined samples before and after thermal oxidation. Vickers microhardness and polarization tests using simulated body fluid (SBF) were also performed. Thermal oxidation generated similar microhardness for polished and machined samples, higher than for polished and non-oxidized condition. On the other hand, oxidation increased the roughness only for polished condition. The corrosion resistance was improved in all oxidized samples, and the best result was found to the intermediate roughness (Ra = 0.76 um), in a machined sample. The results demonstrated that thermal oxidation can be used to overcome machining limitations regarding corrosion resistance, achieving behavior even better than polished samples.

As computer display technology has evolved, so have the aircraft instrument displays pilots use for aircraft control and navigation. With the aid of two different flight training devices – one configured with steam gauges and the other configured with glass cockpit – this study measured aircraft control and navigation differences between two pilot groups. Pilot Group 1 had earned their instrument rating in aircraft equipped with steam gauges, and Pilot Group 2 had earned their instrument rating in aircraft equipped with glass cockpits. Using displays for which they were not trained, each pilot was tested on aircraft control and navigation precision. The test required that pilots complete basic instrument maneuvers and an instrument landing system approach. Using MANOVA, deviations from assigned values were recorded and statistically compared. Study findings indicated that steam gauge pilots transitioning to glass cockpits perform better than glass cockpit pilots transitioning to steam gauge displays.

Within the different types of organisational structures available, it is generally believed that co-operative organisations serve the poor better than the other available alternatives. This belief is based on the fact that these organisations are usually owned and controlled by the people and their objective is to provide services instead of making profits. They are, therefore, considered an important instrument for equitable development, and have been given a prominent role in the national development strategies in many developing countries. It is surprising, however, that the performance of cooperatives is not as satisfactory as it could have been. They have met with only occasional success in Asia. This book explores the causes of this failure.

In this work, we continue the study of the bifurcations of the critical points in a symmetric Caldera potential energy surface. In particular, we study the influence of the depth of the potential on the trajectory behavior before and after the bifurcation of the critical points. We observe two different types of trajectory behavior: dynamical matching and the nonexistence of dynamical matching. Dynamical matching is a phenomenon that limits the way in which a trajectory can exit the Caldera based solely on how it enters the Caldera. Furthermore, we discuss two different types of symmetric Caldera potential energy surface and the transition from the one type to the other through the bifurcations of the critical points.

The texts under consideration in this chapter include Ballard’s first four novels, all of which involve different types of global cataclysms and fall into the apocalyptic subgenre of SF: The Wind from Nowhere, The Drowned World, The Drought and The Crystal World. The latter three are inner-spatial narratives that center on one man’s terrestrial and psychological journey through a dystopian “landscape of decline and desire”; all three protagonists are “becoming-Adams” who seek transcendence by navigating their respective new Edens, “gardens of ruin” that hold the promise of demolition and re-birth. Wind, on the other hand, is a “cozy catastrophe” full of clichés that Ballard wrote to jumpstart his career, although it is much better than some critics (and Ballard himself) have given it credit for.

A new experimental procedure for conducting social comparison experiments was developed to create artificially good and bad performers without the use of confederates. Anagram tasks of 2 different difficulty levels were presented using the fMORI technique (Mori, 2007) such that 2 tasks were viewed separately by 2 groups of viewers wearing different types of polarizing sunglasses. Those shown easier tasks would unwittingly perform those tasks better than the other group. Administration of the new procedure to replicate that used by Alicke, LoSchiavo, Zerbst, and Zhang (1997) with 40 mutually acquainted Japanese undergraduates showed that the new paradigm successfully created good and bad performers as expected. No participant noticed the trick. The results also showed that the participants attributed their performance to their own ability.

The present study investigates the hypothesis that, within personality assessment, the predictive validity of a list of act descriptive sentences will be higher than the validity of a personality inventory on the one hand and that of an adjective checklist on the other. This hypothesis is based on the assumption that people can judge more reliably whether a person will perform a specific act than whether he or she possesses a particular personality trait. Within the validity study, predictors were self‐judgements whereas criteria were peer‐judgements. The predictive validity of the act list was found to be lower than that of the inventory as well as that of the adjective checklist. Moreover, both the act list and the adjective checklist predicted the personality inventory better than the latter predicted the former two. Because of the different functions of self‐ and peer‐judgements within the present study, the former being predictors and the latter criteria, the results are interpreted under the perspective of self‐other attribution differences. Suggestions for constructing a possibly more valid list of act descriptive sentences are given.
