title: Top down or bottom up? Feasibility of water clarity restoration in the lower Karori Reservoir by fish removal

authors: Hicks, Brendan J.

subjects: New Zealand

abstract: As part of an overall ecosystem assessment of lower Karori Reservoir Sabctuary, Wellington, a number of variables are being monitored routinely, including temperature, nutrients, and phytoplankton and zooplankton populations. Ammonium (NH₄) tends to be the dominant species of inorganic nitrogen most of the time except in late winter when nitrate (NO₃) becomes dominant. Total nitrogen concentrations place Karori Sancturay in a mesotrophic to eutrophic category.

title: Maritime security and nuclear cargoes

authors: Smith, Ron C.

subjects: nuclear

abstract: Civilian nuclear operations entail the transportation of sometimes substantial quantities of radioactive material. These can range from large quantities of weakly radioactive fresh fuel for power reactors, with the corresponding removal of highly radioactive spent fuel and operational wastes, to the shipment of small quantities of radioactive isotopes (“sources”) for medical, industrial or research purposes and their subsequent disposal. In relation to the civilian nuclear fuel cycle, there may also be relatively large quantities of radioactive material produced by “back-end” activities, such as the reprocessing of spent fuel to recover plutonium and then create mixed oxide, or MOX, fuel.1 In between these extremes, there are occasional consignments of fresh and spent fuel to and from research reactors, together with the associated wastes. In many of these cases, circumstances will dictate that consignments are dispatched overland, or by air, but there are some cases where a substantial maritime component is entailed and where there will be particular security and safety concerns that arise from that. Traditionally, the focus of this concern has been on the possibility of accidents, which might result in environmental contamination or human harm, but more recently, and certainly since 11 September 2001, the locus of concern has somewhat shifted to risks that might arise from the activities of non-state armed groups, or terrorists (or even pirates). This is the focus of the present review.

title: Visitors' satisfaction with heritage sites in New Zealand: Causes and complexities, clusters and causes

authors: Trinh, Thi Thu

subjects: Heritage Tourism

abstract: The thesis presents findings from a survey of over 1,000 visitors at three New Zealand heritage sites. These sites were Te Puia, the Rotorua Bathhouse Museum and the Rangiriri Battlefield Interpretation Centre. All three represent a key period in New Zealand’s history from the period of approximately 1840 to 1900, but in the case of Te Puia there is also a continuing contemporary cultural importance. This last site, located in Rotorua, was founded as the Maori Arts and Crafts Institute and was established to perpetuate Maori tradition skills in areas such as carving and weaving. Its location was in part determined by the volcanic nature of the valley, long inhabited by members of Te Arawa tribal people. The site has a strong connection with tourism as Te Arawa have entertained tourists from the mid-nineteenth century in the volcanic area. The site therefore represents a tourism site from the perspective of history, culture and natural heritage. The Bathhouse Museum represents a period of late colonial architecture while the third site, the Rangiriri Battlefield is based on the remnants of the Pa (Maori fortifications) that was the site of a battle between the colonial government forces and the Maori Kingi movement on November 23rd 1840.

The motive for the research was to provide a profile of visitors for the respective sites and their management, and then to assess to what degree socio-demographics might be explanatory variables in determining future visitation. The core theories being employed revolved around concepts of levels of interest in heritage and historic sites, the intellectual search for knowledge, and the degree to which people became involved in the activity of heritage site visitation. The work was driven by the finding that only about 11 per cent of visits to cultural tourism sites were ‘purposeful’ tourists as defined by McKercher and Du Cros (2002). Being purposeful implies having specific degrees of interest, of becoming involved and possibly seeking meanings that implied senses of identity. That is, self-awareness accrued from having a better understanding of the past as a means of knowing about the present. This conceptualisation implies use of the theories of involvement, benefits and self-awareness, and the managerial aspects of interpretation.  Normally such an approach has been seen by many researchers as a determinant of satisfaction, but in this thesis satisfaction is not seen as simply an end to a process. Rather, this thesis argues that to be satisfied entails not only cognitive and affective components, but also the conative. That conative component can include making recommendations to others, making visits to other heritage sites, or joining organisations associated with heritage sites such as the New Zealand Historic Place Trust. These form key themes in the literature review.

Unfortunately, while these premises emerged from the literature review and informed the hypotheses that are later described in the thesis, they were not wholly supported by the data. It is suggested that one reason for this, from a statistical perspective, was that measures used were subject to multi-collinearity and auto-correlation – put simply, many of the variables are not independent from each other. For example, it is suggested that satisfaction is actually enhanced by subsequently being able to make recommendations to friends and others; that the act of making a recommendation enhances one’s own self in both the eyes of that friend or through an enhanced self- perception of being helpful, and thus auto-correlation may exist between these variables.

This realisation thus leads, in the conclusions of Chapter Eight, to new suggestions for potential future researchers concerning ways of looking at the nature of involvement that draw on distinctions between situational and enduring involvement. Finally, it also needs to be noted that tourists are not lay historians, but are the makers of their holidays, and hence the debate is contextualised within the act of being on holiday, which itself is a period of escape and relaxation for many. Hence the relationships being examined in this thesis are complex, interactive and yet rewarding to untangle.
