Developing New Tourism Services: Dinosaurs a New Drive Tourism Resource for Remote Areas

This paper examines issues encountered when developing new tourism services generally, and specific aspects relating to the development of remote area dinosaur fossil fields for tourism. It studies two sites, one in the USA and one in Australia. Access to both sites is by minor roads, and both sites are characterised by long drives separating the sites from small communities that offer limited infrastructure and few other attractions for visitors. In both areas, however, tourism is seen as one of the few possible ways to sustain existing communities in the face of declining primary-industry-based employment. In general, tourists visiting these areas are on touring holidays of two weeks’ duration or more where the attraction is the general attributes of the region as well as to a lesser extent their interest in dinosaur fossils. These provide a potential resource for remote-region economic development through commodification as a new tourism attraction. Development of dinosaur fossil finds as a tourism resource is conceptualised here as new service development. Developing new tourism services, especially in remote regions, is challenging and has not been well examined in the tourism literature. The new service development process used in this case study first examines the characteristics of the existing tourists travelling through the region. The characteristics of a number of potential market segments currently interested in dinosaur fossils were then examined and contrasted with the existing market. This is conceptualised on a specialist-generalist spectrum of interest in fossils. A study of the tourist service features associated with dinosaur fossil tourism in remote regions of the USA was conducted, leading to the identification of a number of possible incremental development opportunities. The paper then takes a strategic approach to examining potential new tourism service development related to dinosaur fossils in remote regions of Queensland, Australia. In particular, it describes use of information about existing services in similar regions as the basis for ideas about development as well as comparison between existing and potential markets.

A theoretical comparison of two optimization methods for radiofrequency drive schemes in high frequency MRI resonators

In this paper, numerical simulations are used in an attempt to find optimal Source profiles for high frequency radiofrequency (RF) volume coils. Biologically loaded, shielded/unshielded circular and elliptical birdcage coils operating at 170 MHz, 300 MHz and 470 MHz are modelled using the FDTD method for both 2D and 3D cases. Taking advantage of the fact that some aspects of the electromagnetic system are linear, two approaches have been proposed for the determination of the drives for individual elements in the RF resonator. The first method is an iterative optimization technique with a kernel for the evaluation of RF fields inside an imaging plane of a human head model using pre-characterized sensitivity profiles of the individual rungs of a resonator; the second method is a regularization-based technique. In the second approach, a sensitivity matrix is explicitly constructed and a regularization procedure is employed to solve the ill-posed problem. Test simulations show that both methods can improve the B-1-field homogeneity in both focused and non-focused scenarios. While the regularization-based method is more efficient, the first optimization method is more flexible as it can take into account other issues such as controlling SAR or reshaping the resonator structures. It is hoped that these schemes and their extensions will be useful for the determination of multi-element RF drives in a variety of applications.
