  • How does enterpreneurship within rural tourism diversify rural ecomonies - Banks Peninsula - New Zealand?

    Cloesen, U. (2007)

    Conference paper
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Rural tourism is considered an economic alternative for farmers who are facing sinking profits and require additional income. This in turn can lead to an entrepreneurial response. The distinction between simple diversification and entrepreneurial response. The distinction between simple diversification and entrepreneurship takes place when seperate legal entities for new ventures are formed. Entrepreneurship is commonly defined as creating something of value from practically nothing (Timmons in Morrison et. al., 1999, p.10). It is the process of creating or seizing an opportunity, and pursuing it regardless of the resources currently personally controlled. this involves the definition, creation and distribution of value and benefits to individuals, groups, organisations and society at large. One example for this is the establishment of the first private rural walkway in New Zealand on Banks Penninsula.

  • Becoming a baker:- from 'hopeful reactor' to' passion honer'

    Chan, S. (2007)

    Conference paper
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper focuses on emergent themes from interviews with young apprentice bakers. It is part of a larger study of how young people become bakers. The overall objective of the main study is to explore the apprenticeship journeys of young apprentices learning their trade in the New Zealand baking industry. This paper reports on interviews carried out with second year apprentices. It reveals that the majority of the apprentices in the study, who had taken on an apprentice due to lack of other choices, are gaining confidence in their abilities. This confidence is shown in their building passion for the trade and their growing commitment towards becoming bakers.

  • Analysis of results in simulation and modeling of CDMA systems

    Kolahi, Samad (2007-07-01)

    Conference paper
    Unitec

    In this paper, using discrete event stochastic simulation by batch-means, new results have been obtained by analysing the sensitivity of CDMA blocking probability for a given traffic load against various number of calls per batch and confidence intervals. It is found that for the system under study one long simulation with one million call arrivals produce approximately 99% confidence in results while it needs 100,000 calls to achieve 95% confidence. For system under study and with 27 Erlang of traffic, the blocking probability is 0.0202 with 99% confidence and 0.0192 with 95% confidence. The impact of warm-up period on CDMA simulation is discussed. Situation with three tiers of neighbouring cells are considered when mobile compares three base stations and chooses the base station with the strongest signal.

  • The contribution of goal setting to the success of eCommerce systems among small and medium enterprises

    Ghandour, Ahmad; Benwell, George L; Deans, Kenneth R (2007-06)

    Conference paper
    University of Otago

    The purpose of this paper is to explore the role of goal setting as contributing factor for eCommerce systems (ECS) success in small and medium enterprises (SMEs). Based on the literature review relative to eCommerce in SMEs, this research postulates that goal setting influence the success of ECS in SMEs. The success of ECS in SMEs is the dependent variable the dimensions of which are identified by using DeLone and McLean success model. The output result of this paper is a conceptual model identifying the relevant dimensions of both success and goal setting and the resultant hypotheses that require empirical research to validate the proposed model.

  • A preliminary investigation of the stability of Geographically-Weighted Regression

    Whigham, Peter A; Hay, Geoff (2007-12-06)

    Conference paper
    University of Otago

    This paper describes preliminary work analysing the stability of parameter coefficient estimates for Geographically-Weighted Regression (GWR). Based on a large dataset (35721 points) various random samplings of this data were performed and models built using GWR. An analysis of the coefficient values for the independent variables showed that these values could varying significantly both between runs and between sampling sizes. This suggests that the results from GWR must be carefully considered in terms of the form of data, assumed coefficient surface being modelled, and the confidence of the resulting parameter estimates.

  • Relationship building in small businesses - the case of linking personal selling with collectivism

    Fam, Kim-Shyan; Simpson, Lisa; Yang, Lin; Chung, Kim-Choy (2007-11-02)

    Conference paper
    University of Otago

    This paper examines the link between personal selling and collectivism found in small clothing and shoe retailers in New Zealand, Portugal and Hungary. The study uses three culturally similar, predominately Anglophone nations, as most prior research with a cultural factor is conducted in culturally dissimilar nations and the results are hard to generalise across culturally similar countries. The results of the study show a strong link between choice of personal selling as a promotional tool and the collectivist orientation on the part of the retailers. The main conclusion of this paper therefore, is that where there is a definitive link between personal selling and collectivism in small clothing and shoe retailers, there also needs to be an understanding on the part of these retailers of how to most effectively use personal selling in their business.

  • Space, freedom, and law: maybe space is all that matters

    Martin, Peter (2007-12-06)

    Conference paper
    University of Otago

    The traditional causal, vectorial approach to formulation of physical law is contrasted to the analytic approach which is based on variational principles. Reviewing the work of Toffoli, these two “paradigms” are considered in relation to the idea of parsimony arising from prodigality. The second law of thermodynamics and Darwinism are taken as further examples of global, non-causal principles similar to the variational principles, which may also be considered as cases of parsimony arising from prodigality, or law arising from freedom. Space is considered in a generalized, or abstract, sense, not as an arena for location of events and application of laws, but rather as that which affords freedom, and hence as that which may be both necessary and sufficient as the ultimate basis of physical laws–i.e. “all that matters”. As a final remarkable example of constraint, or law, arising as an epiphenomenon of space, the variational-principle analogue of Bayerlein, Sharp, and Wheeler, from geometrodynamics, is mentioned, which is the basis of Barbour’s theory that time itself arises as an illusory epiphenomenon from a space of all possibilities.

  • Assessment of the performance of image fusion for the mapping of snow

    Sirguey, Pascal; Oltmer, Sven; Mathieu, Renaud (2007-12-06)

    Conference paper
    University of Otago

    The assessment of the performance of multi-resolution image fusion, or image sharpening methods, is difficult. In the context of binary classification of snow targets in mountainous terrain, fusion methods were applied to help achieve more accurate mapping. To quantify objectively the gain of information that can be attributed to an increase in spatial resolution, we investigate the Mean Euclidean Distance (MED) between the snowline obtained from the classification, and a reference snowline (or a ground truth line), as a relevant indicator to measure both the discrepancy between datasets at different spatial resolutions, and the accuracy of the mapping process. First, a theoretical approach based on aggregating detailed reference images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) showed that the MED has a linear relationship with the pixel size that makes it suitable to assess images of different resolutions. Secondly, we tested the MED to snow maps obtained ‘with’ or ‘without’ applying a fusion method to the MODerate Resolution Imaging Spectroradiometer (MODIS). We demonstrated that the MED identified a significant value added, in terms of mapping accuracy, which can be attributed to the fusion process. When the fusion method was applied to four different images, the MED overall decreased by more than 30%. Finally, such a ‘feature based’ quality indicator can also be interpreted as a statistical assessment of the planimetric accuracy of natural pattern outlines.

  • The impact of customer focus to the success of eCommerce systems among small and medium enterprises—a conceptual framework

    Ghandour, Ahmad; Deans, Kenneth R; Benwell, George L (2007-12-03)

    Conference paper
    University of Otago

    This paper conceptualizes the role of customer focus as a contributing factor to the success of eCommerce system (ECS) when it is implemented by small and medium enterprises (SMEs). It postulates that customer focus influences the success of ECS. The success of ECS in SMEs is the dependent variable, the dimensions of which are identified by using DeLone and McLean success model. The output of this paper is a conceptual model that identifies the relevant dimensions of both success and customer focus and the resultant hypotheses that require empirical research to validate the proposed model.

  • The emergence and distribution of species in a gradient-based spatially-structured evolutionary algorithm

    Dick, Grant (2007-12-06)

    Conference paper
    University of Otago

    The ability to discover and maintain multiple solutions within a single run is a desirable property for evolutionary algorithms. Researchers have previously turned to many biologically-inspired methods for inspiration to produce niching evolutionary algorithms. This paper extends previous work on the Gradient-Based Spatially-Structured Evolutionary Algorithm, which attempts to embody the concept of parapatric speciation within an evolutionary algorithm. Through an comparison of the evolved population with that of an idealised, perfectly proportioned population, we show that the distribution of population members among the niches of a given problem’s fitness landscape does not rely on the global properties of the landscape. Rather, the allocation of individuals to peaks relies on the relative values of neighbouring peaks with regard to their spatial relationship in the fitness landscape.

  • HD aerial video for coastal zone ecological mapping

    Chong, Albert K (2007-12-06)

    Conference paper
    University of Otago

    The paper discusses a recent test of using High Definition (HD) video camera to obtain aerial mapping images for coastal zone study. Real-Time GPS was used to capture the ground control. It was revealed that the vibration from the aircraft has an adverse effect on the video footage. Consequently, each video frame was deinterlaced to obtain the odd and even fields as sub-frames. Deinterlacing removes the effect of aircraft vibration; however the process reduces the video frame format size to a sub-frame size which is a half of the original format size. The video camera was calibrated at full format size so the image must be rebuilt to full format size in order to achieve the required spatial accuracy. Tests show that the stereo-digitized 3D coordinate of beach features is similar to still-frame digital images at the same flying height. Because videoing does not require precise exposure timing as in the case of still-frame photography, HD video has a vey important advantage over conventional still-frame aerial photography for aerial mapping.

  • Display of interactive artwork: pilot test of two different interfaces

    Burrows, Gary; Hauber, Joerg; Regenbrecht, Holger (2007-12-06)

    Conference paper
    University of Otago

    The display of interactive artwork plays an increasingly important role in modern museums and galleries. However, the reaction of visitors has not been extensively tested to date. We present a pilot study that investigates viewer's reactions towards two interactive display prototypes that were designed to present famous artwork in a new and more engaging way. We describe the first iteration cycle of a questionnaire we composed which especially targets viewer satisfaction in a gallery context. The results of our first pilot study indicate that (1) interactive displays in galleries can create an engaging and exciting experience and (2) that they can be especially suitable to present education about art in a new and more involving way.

  • Point allocation inside polygons and GWR: an experimental analysis with survey data

    Francisco, Eduardo de Rezende; Whigham, Peter A; Moore, Antoni (2007-12-06)

    Conference paper
    University of Otago

    The aim of this paper is to analyse different alternative implementations for a problem defined as "point allocation inside polygons" for Geographically Weighted Regression (GWR). The problem involves situations where the precise location of each observation is not known - just its district, municipality or region, i.e. a polygon geographical location. However, associated data were available that could potentially allows point placement of observations. These analyses were applied in a Income predicting model based on electricity consumption from a survey for a power distribution company in Sao Paulo, Brazil. Completely spatially random allocation and allocations based on spatial distributions of population (universe) and of the independent variable (electricity consumption) were utilized. Results showing the coefficients of determination (R2) suggest that a more realistic measure of the relationship between these two constructs could be evaluated.

  • Antecedent of brand trust in e-tertiary education

    Chung, Kim-Choy; Fam, Kim-Shyan; Holdsworth, David K (2007-06-02)

    Conference paper
    University of Otago

    Trust decreases the perceived risk of using a service. Since e-learners have no direct contact with the education providers, trust plays an important role in an e-tertiary setting. In a review of the literature, hypotheses are developed that suggest that the antecedent of brand trust in e-tertiary education is related to institutional and courseware design assurance factors, site quality and public awareness. A conceptual model summarizing the hypotheses is subsequently validated in an empirical study.

  • Spatial analysis of home range, core area and habitat selection of red deer (Cervus elaphus) on an extensively managed high-country station

    Netzer, Michael; Whigham, Peter A; Dickinson, Katharine; Lord, Janice (2007-12-06)

    Conference paper
    University of Otago

    The aim of this research was to determine the behavior and habitat selection of red deer (Cervus elaphus) hinds during the calving period, on an extensively managed rangeland in the high-country of New Zealand’s South Island. The research was developed using ArcView and eCognition software, GPS collars on five red deer hinds, an aerial photograph and topographic data. The results showed that three out of the five study deer escaped the original study paddock into adjacent extensive paddocks. The deer did not use the entire study paddocks they were in, but instead formed distinct home ranges (total area of movement) and core areas (areas of intensive use, 45% of deer locations). These home ranges were highly variable in size from 225 ha. To 36 ha.. Core areas ranged from 102 ha. To 36 ha.. The variation in size of home ranges and core areas was directly related to the size of the paddock, and indirectly to social constraints within the paddock. The results suggest that deer within these extensive paddocks are under strong densitydependent effects during the calving season that may be forcing some hinds (probably less-dominant hinds) to the marginal edges of the pasture, where they may eventually escape. Habitat selection indicated, that while red deer often selected the naturalized pasture grass areas (high in metabolized energy), tussock grassland, when present in the home range, was also highly selected for. The selection of tussock grasslands was probably a result of tussock habitat providing both good cover/security during the calving season, and the presence of reasonably good forage in the inter-tussock area.

  • Spatial variation in the association between neighbourhood deprivation and access to alcohol outlets

    Hay, Geoff; Whigham, Peter A; Kypri, Kypros; Langley, John (2007-12-06)

    Conference paper
    University of Otago

    Background: People who live in poor areas suffer higher mortality than those living in wealthier areas. People who live in poor areas in New Zealand have better access to alcohol and this association appears to vary spatially. We sought to investigate this spatial non-stationarity using Geographically Weighted Regression. Methods: The location of bars was geocoded for all of New Zealand and closest facility analysis was used to calculate distance to the nearest bar from each meshblock. A neighbourhood level census-based index of socioeconomic deprivation, and urban/rural status data were added as inputs to a Geographic Weighted Regression model to investigate spatial variation in the association between access to alcohol outlets and deprivation. Results: Spatial non-stationarity was discovered in deprivation and urban/rural status parameters with some large rural areas of New Zealand exhibiting significant departures from the global model of the association between distance to the nearest bar and neighbourhood deprivation. Conclusions: Lack of association discovered for rural areas may be the result of spatial heterogeneity. Research into the association between deprivation and access to alcohol should consider rural areas individually for environmental inequity rather than relying on global models showing no association.
