    Turbo smaragdus is a herbivorous gastropod of the intertidal and sub-littoral zones, which is distributed widely along the coastline of New Zealand. This study sought to investigate the population and reproductive ecology of Turbo on the Kaikoura Peninsula. This involved the determination of: spatial and temporal distribution patterns, associations with other herbivorous molluscs and algal species, recruitment of juveniles, morphometric relationships, population length-frequency structures, growth rates, spawning seasons, trends exhibited in a reproductive cycle, sex ratio, size at sexual maturation and fecundity. Turbo have a broad distribution that varies significantly both within and between sites. Transect surveys determined that Turbo have an aggregated distribution, and were present from the upper eulittoral into the sub-littoral to depths of 3m with largest numbers generally occurring in the mid-eulittoral. Juveniles (shell lengths ≤ 15mm) occurred widely on the vertical profiles of the shores sampled, but larger individuals were more common in the lower eulittoral. Sub-littoral populations were composed of larger individuals, with shell lengths ≥ 35mm. As Turbo grow, shell and operculum height, width and length increase linearly and shell, operculum, body tissue and gonad weight exponentially. Tag-recapture data indicate that growth rates decrease with increasing size of individuals. At the sites sampled, individuals can grow to a shell length of 40mm at which the von Bertalanffy growth curve predicts they will be approximately ten years of age. Growth rates of Turbo vary seasonally, with greatest rates occurring between November-March, and the slowest between August-November. Spatial variation was also shown to occur between two populations, with greater growth rates occurring in the area of slightly greater exposure to wave action. The absence of age classes in length-frequency histograms suggests that recruitment failure or high mortality rates may occur during some years. Sexual maturation of both male and female Turbo generally occurred between shell lengths of 20-25mm, although a few individuals were observed to mature at both smaller and larger sizes. Energetic investment in reproductive effort, which is indicated by increasing gonad size and fecundity, increases with increasing shell lengths. The populations sampled exhibited a 1:1 sex ratio. Turbo are broadcast spawners and have a distinct annual reproductive cycle. A major spawning event occurred on the Kaikoura Peninsula during February-March 1991 and a minor event in January 1992. Immediately succeeding the 1991 spawning period, the gonads of both sexes were reduced in volume and relatively depleted of mature gametes. Gametogenesis occurred within several months of spawning, with the immature gametes developing slowly throughout the winter and accelerating in growth in the spring to produce gonads that were densely packed with mature gametes several months prior to the January 1992 spawning event.

  • The changing agricultural geography of Southland, 1878-1940.

    Kellaway, Roger George (1970)

    Masters thesis
    University of Canterbury Library

    The evolution of the agricultural system of Southland was a long-term process. It has roots that stretch back to Britain before the agricultural revolution and it has not yet ended. Indeed, it probably will never end because agricultural systems are dynamic entities. The aim of this work bas been to consider the manner in which the agricultural geography of Southland has reacted to the changes that have taken place in the profitability ot various forms ot agricultural production, the introduction of new types of agricultural technology, and the impact of new modes of transport.

  • Putting the real back into realistic job preview : an analysis of realistic job preview method and function.

    Atkinson, Caroline Leigh (1993)

    Masters thesis
    University of Canterbury Library

    Realistic Job Previews (RJP's) have developed out of a requirement for some form of voluntary turnover intervention. Most of the literature examines the processes which mediate RJP effectiveness but has recently begun to investigate the contents of RJP's and the methods of presenting them. As much of the research has been characterised by inconsistent results, this study hypothesises that a closer examination of the methods of presenting RJP's will assist in clarifying some of the unresolved issues. Intensional Simulation (Roleplay) method is proposed as a more suitable format for RJP presentation than either brochure or audio-visual RJP's. Sixty stage one psychology students were placed in one of three preview groups: brochure, video or roleplay. After the presentation of the preview, subjects were required to complete a small test and questionnaire, and to participate in a short interview. The roleplay method was found to be more realistic overall than the brochure format, contain a greater amount of information and be more personally relevant to the subjects. There was no support for the hypotheses suggesting that, compared to other methods, roleplay subjects would retain more information from the preview, make fewer job acceptance decisions and be more likely to change any decision to accept a job offer. These results are examined in light of previous RJP research and discussed in relation to the current employment climate in New Zealand. The limitations of this research are noted, along with a discussion of its practical implications.

  • 'Ageism' in personnel selection.

    Sewell, Christine A. (1988)

    Masters thesis
    University of Canterbury Library

    The present research involved two independent studies. The first study looked at "ageism" or age discrimination in selection interviews. The effects of applicant age, information exposure and job status were examined in the interview. The specific research question addressed was whether exposure to information about successful older workers would reduce discrimination against older employees in interview settings. This study was carried out with a sample of 61 managers. Prior to !Ylaking selection decisions about a young applicant (25 years old) or an older applicant (48 years old), subjects read an article which contained either age-related information or neutral information. The age-related information was designed to mitigate against age bias. Videotaped job interviews were then viewed by the subjects who were required to make job performance evaluations and hire decisions about the applicant. Evidence of ageism against the old applicant was found. However as predicted, managers exposed to the age-related information gave significantly more favourable evaluations to the old applicant and were more willing to hire him than the young applicant. The second study addressed a very current research concern - the generalisability of findings in selection research using student samples to managerial samples. The same methodology was repeated with a sample of 119 undergraduate students. The results showed significant differences in students' selection decisions. The students exposed to age-related information gave more favourable ratings to the young applicant, and were not willing to hire the old applicant. The implications of these results are discussed.

  • Maximum local scour depth at bridge piers and abutments

    Kandasamy, JK; Melville, Bruce (1998)

    Journal article
    The University of Auckland Library

    Results of recent laboratory investigations of local scour at bridge piers and abutments are presented. Similarities between the principal vortex occurring in local scour holes at abutments and the horseshoe vortex and downflow at piers are highlighted. Pier and abutment laboratory data, collected near the threshold conditions for sediment movement, display similar trends in the variation of scour depth with length and flow depth. This variation is best described in a three dimensional plot. A simple equation, that can be used to predict the maximum local scour depth at either piers or abutments aligned perpendicular to the flow, is presented and compared with field data.

  • Stratigraphy and chronology of the Stent tephra, a c. 4000 year old distal silicic tephra from Taupo Volcanic Centre, New Zealand

    Alloway, Brent; Lowe, DJ; Chan, Robert; Eden, D; Froggatt, P (1994-03)

    Journal article
    The University of Auckland Library

    Tephrostratigraphic and chronologic studies in two areas of the North Island have identified a previously unrecorded, thin, distal silicic tephra derived from the Taupo Volcanic Centre. In Taranaki, three radiocarbon ages of the uncorrelated tephra are consistent with the independent radiocarbon chronology obtained from enveloping Egmont???sourced tephras. In western Bay of Plenty, where the uncorrelated tephra is also directly dated, it is overlain by Whakaipo Tephra (c. 2.7 ka) and underlain by Hinemaiaia Tephra (c. 4.5 ka). From these sites in Taranaki and western Bay of Plenty, seven radiocarbon dates obtained on the uncorrelated silicic tephra yield an error???weighted mean age of 3970 ??31 conventional radiocarbon years B.P. The ages on the uncorrelated tephra (informally referred to as Stent tephra) from both areas are statistically identical but significantly different from those on both Waimihia and Hinemaiaia Tephras. The occurrence of Stent tephra in Taranaki, c. 160 km upwind from the postulated source area, and in western Bay of Plenty, suggests that it represents the product of a moderately large plinian eruption. Until recently, its validity as a discrete eruptive event had been problematical, because a near???source equivalent deposit between Waimihia and Hinemaiaia Tephras was not recognised in the Taupo area. However, a revised stratigraphy proposed by C. J. N. Wilson in 1993 for eastern sectors of the Taupo area shows that multiple tephra layers were erupted from Taupo volcano between c. 3.9 and 5.2 ka. Of these newly recognised layers, unit???g???the product of a moderately large eruption (???0.15 km3) at c. 4.0 ka???is tentatively correlated with Stent tephra. Other eruptive units recognised by Wilson are either too old or too small in volume to be considered as likely correlatives.

  • Sediment control at water intakes

    Wang, YL; Odgaard, AJ; Melville, Bruce; Jain, SC (1996)

    Journal article
    The University of Auckland Library

    Submerged vanes are shown to be effective in preventing bed load transport from entering water intakes. By generating a secondary circulation in the flow, the vanes change the magnitude and direction of the bed-shear stresses and cause a redistribution of the flow and sediment transport in the area affected by the vanes. As a result, the riverbed aggrades in one portion of the channel and degrades in another. The performance of two vane installations, designed according to guidelines developed earlier, are evaluated by comparing the bed topography before and after vanes were installed. The design guidelines, which utilize a numerical model developed earlier, are shown to be appropriate. The guidelines apply only when the intake flow is small enough that the withdrawal causes little change in the river flow velocity in front of the intake.

  • The applicability of verbal processing strategies to recall of familiar songs

    Booth, Gregory; Cutietta, RA (1991)

    Journal article
    The University of Auckland Library

    One hundred thirty-five undergraduate nonmusic majors participated in a free-recall task in which they were asked to remember the titles of 12 songs that they heard in different sequences. The investigators were seeking evidence that cognitive categorization of the titles was based on the musical element of style. The purpose was to compare the subjects development of any apparent categorization of the musical stimuli with categorization strategies that research suggests apply to verbal information. Results indicate that many subjects seemed to categorize the musical stimuli by applying verbal stylistic labels. Furthermore, the subjects' subsequent strategies for manipulating verbal labels show many similarities to, and some differences from, how subjects would be expected to process purely verbal information. Educational implications and ideas for future research are suggested.

  • Changing food habits of New Zealanders of European descent 1870-1970 : an anthropological examination of the mechanisms of cultural change

    Mitchell, Janet (1995)

    Masters thesis
    University of Otago

    Between 1870 and 1970 both the culture and food habits of New Zealand European society underwent change. In the past food habits have been examined using either an historical approach or consumption and nutritional data. These approaches however have not explained how change has occurred. Anthropologists working in other countries have approached this problem in several different ways. A structural approach to meals and the meal system gives answers to why food habits are slow to change. But this approach does not address change. A sociological approach which takes account of changes in the society explains how the interplay of societal factors can cause change but it does not account for the stability of food habits over long periods. This study combines these approaches to give an answer to the phenomenon of stability and change which characterised European New Zealanders' food habits from 1870-1970. Evidence of change in food habits and in the culture was linked to changing social conditions, ideas about food and changes in technology. Material on the topic was collected from written sources - in particular recipe books were found to be a valuable tool. In this study the evidence established that while all of the factors mentioned above played a role in the transformation of food habits in European New Zealand society, substantive change at any one time was linked to the social conditions that influenced women's role in the household
