Visitor profiles and environmental attributes, especially of birds, attracting visitors to Lamington National Park: Tourist attitudes and economic issues

Uses a sample of 622 day and overnight visitors to the O’ Reilly’s/Green Mountains site of Lamington National Park, Queensland, Australia, to identify their socio-economic and other pertinent characteristics and the main reasons and attributes that attract them to the site. Particular attention is given to birds and their attributes as attractions. The primary economic injection accruing locally as a result of visits is examined and the difference that the presence of birds makes to local expenditure by visitors is explored. The extent of support for and objection to the introduction of a fee for entering Lamington National Park is estimated. The many suggestions received from visitors for environmental improvements at this site are discussed. It is suggested that unless a way can be found to regulate the number of visitors to this site and obtain extra funds to finance improvements at this site, the magnitude of many of these problems will grow. This will necessitate a fresh look at the desirability or otherwise for charging entry fees to Lamington National Park.

Attitudes to entry fees to National Parks: Results and policy implications from a Queensland case study

Examines visitor attitudes and whether visitors are willing to pay to enter Lamington National Park and under what circumstances they would do so. First a sample of visitors is asked a general (normative) question as to whether visitors should pay to visit Lamington National Park and in another question (positive) they are asked whether they would be more willing to pay if the money collected would be invested in the park to improve visitor facilities and for conservation work. The results show that visitors are more willing to accept the ‘user-pays’ principle if the money will be used for the benefit of the national park and its visitors. It was found that foreigners are more in support for a ‘user-pay’ fee than Australians, and among Australians, those visitors from Queensland are the least willing to accept the idea of a user-pay fee to enter the park. The results indicate that if visitors can be shown the benefits (both for visitors and for conservation) of charging an entry fee, then visitors are more likely to support such a concept than when they are unaware of the benefits of a user-fee. The study shows that on average foreigners are willing to pay more than Australians. Finally, the regression results identify significant factors influencing visitors’ attitudes and suggested amounts to visit the national park.

Public attitudes to the use of wildlife by Aboriginal Australians: Marketing of wildlife and its conservation

Indigenous Australians have socioeconomic attributes similar to those of residents in some developing countries. Their utilisation of wildlife could add to their economic opportunities. Attitudes of a sample of the Australian public towards the subsistence use of wildlife by Indigenous Australians and whether or not they should be allowed to sell wildlife and wildlife products are examined. Allowing such possibilities could provide economic incentives for nature conservation among local people. We explore whether those sampled believe that Indigenous Australians should do more than other groups and institutions to conserve Australia's tropical species, and whether or not they should be allowed to take common as well as endangered wildlife species for food. Attitudes of the sampled public towards Indigenous Australians earning income from trophy hunting and from the harvesting of northern long-necked turtles for the pet trade are canvassed. The possible conservation consequences of sale of wildlife by Indigenous Australians are discussed.

Public valuation of and attitudes towards the conservation and use of the Hawksbill turtle: An Australian case study

Managing hawksbill turtle populations for use and conservation requires (i) adequate scientific understanding of their population status and dynamics and (ii) consideration of the public’s attitudes to this species. This study employs experimental surveys to assess the Australian public’s attitudes towards the hawksbill turtle, their knowledge of it, their views about its sustainable commercial harvesting, and their support and financial contribution for the species’ conservation. Contingent valuation reveals that the Australian public’s willingness to contribute to the conservation of the hawksbill turtle is high even in comparison to threatened Australian bird and mammal fauna. Most of this stated contribution is based on the intrinsic (non-use) value associated with the hawksbill turtle. It seems that the Australian public will only accept its harvesting if the sustainability of this is assured and its population is more secure. The CITES categorisation of the hawksbill as an Appendix I species hampers the development of techniques for its sustainable use.

Image quality assessment and medical physics evaluation of different portable dental X-ray units

Introduction: Recently developed portable dental X-ray units increase the mobility of the forensic odontologists and allow more efficient X-ray work in a disaster field, especially when used in combination with digital sensors. This type of machines might also have potential for application in remote areas, military and humanitarian missions, dental care of patients with mobility limitation, as well as imaging in operating rooms. Objective: To evaluate radiographic image quality acquired by three portable X-ray devices in combination with four image receptors and to evaluate their medical physics parameters. Materials and methods: Images of five samples consisting of four teeth and one formalin-fixed mandible were acquired by one conventional wall-mounted X-ray unit, MinRay (R) 60/70 kVp, used as a clinical standard, and three portable dental X-ray devices: AnyRay (R) 60 kVp, Nomad (R) 60 kVp and Rextar (R) 70 kVp, in combination with a phosphor image plate (PSP), a CCD, or a CMOS sensor. Three observers evaluated images for standard image quality besides forensic diagnostic quality on a 4-point rating scale. Furthermore, all machines underwent tests for occupational as well as patient dosimetry. Results: Statistical analysis showed good quality imaging for all system, with the combination of Nomad (R) and PSP yielding the best score. A significant difference in image quality between the combination of the four X-ray devices and four sensors was established (p < 0.05). For patient safety, the exposure rate was determined and exit dose rates for MinRay (R) at 60 kVp, MinRay (R) at 70 kVp, AnyRay (R), Nomad (R) and Rextar (R) were 3.4 mGy/s, 4.5 mGy/s, 13.5 mGy/s, 3.8 mGy/s and 2.6 mGy/s respectively. The kVp of the AnyRay (R) system was the most stable, with a ripple of 3.7%. Short-term variations in the tube output of all the devices were less than 10%. AnyRay (R) presented higher estimated effective dose than other machines. Occupational dosimetry showed doses at the operator`s hand being lowest with protective shielding (Nomad (R): 0.1 mu Gy). It was also low while using remote control (distance > 1 m: Rextar (R) < 0.2 mu Gy, MinRay (R) < 0.1 mu Gy). Conclusions: The present study demonstrated the feasibility of three portable X-ray systems to be used for specific indications, based on acceptable image quality and sufficient accuracy of the machines and following the standard guidelines for radiation hygiene.

"They're scared of it": Intergroup determinants of attitudes toward children with HIV

The study used an intergroup perspective to explore teachers' willingness to teach children with HIV within mainstream education. One hundred thirty-eight teachers from 13 high schools across the United Kingdom participated in a survey. The results suggest that previous contact with an individual who was HIV positive (whether an adult or a child) was strongly associated with greater willingness to teach a child with HIV. However, this effect disappeared when intergroup anxiety, positive affect, and positive beliefs were included as covariates. There was little evidence that instrumental variables (i.e., relatively pragmatic concerns about infection) were associated with willingness to teach. Participants who had some contact reported lower fear of contagion from a child with HIV, but there was no evidence that this was associated with overall attitudes. The results are interpreted to suggest that interventions to reduce prejudice should not simply concentrate on improving knowledge about HIV transmission.
