The aim of this paper was to explore the role of the media within the context of tourism, specifically with regard to how the media has influenced the activities and perceptions of the tourism sector. In this paper, the term ‘media’ is referred to as mass communication, specifically with regard to newspapers, magazines and broadcasting. It is important to gain a better understanding of the ways in which the media has interacted with the tourism sector, as this information can provide practitioners and academics with insights as to how the media can best be employed to benefit stakeholders of the tourism industry. Lessons can be learned from the past so that the experience gained from it can contribute to best practice in the future. In this way, strategies can be developed to minimise the vulnerability of the tourism sector to damaging or erroneous portrayals of it and its activities in the media.
The case study method was used to explore the role of the media within the context of tourism. Four case studies provided insights on this topic. The four case studies were selected based on their diversity, within the context of the tourism sector, and because they covered a considerable period of time. These variables provided the researchers with a wide-ranging perspective on the topic.
The paper firstly focuses on the 1920’s Waiters’ Strike in the resort town of San Sebastián, Spain, and discusses the role of the media in relation to this event. The second case investigates the use of the media as a destination-marketing tool and reflects on an early manipulation of this process by the German authorities in the documentary Olympia, a film produced for the summer Olympics in 1936. The third case study reports on the manner in which the media has created tensions between connoisseurs of fine food and drink and hospitality industry professionals, and its subsequent implications on service quality. The final case investigates the role of the media in reducing demand for hospitality services in Melbourne on New Year’s Eve 2000.
Through an analysis of these diverse, but important case studies, it can be seen that the media has had, and continues to have, an impact on the development of the tourism industry in both positive and negative ways. The limitations of this research are discussed and recommendations are made for further research that will assist in developing a more comprehensive typology of the media’s role in tourism.

Four sites located in the north-eastern region of the United States of America have been chosen to investigate the impacts of soil heterogeneity in the transport of solutes (bromide and chloride) through the vadose zone (the zone in the soil that lies below the root zone and above the permanent saturated groundwater). A recently proposed mathematical model based on the cumulative beta distribution has been deployed to compare and contrast the regions' heterogeneity from multiple sample percolation experiments. Significant differences in patterns of solute leaching were observed even over a small spatial scale, indicating that traditional sampling methods for solute transport, for example the gravity pan or suction Iysimeters, or more recent inventions such as the multiple sample percolation systems may not be effective in estimating solute fluxes in soils when a significant degree of soil heterogeneity is present. Consequently, ignoring soil heterogeneity in solute transport studies will likely result in under- or overprediction of leached fluxes and potentially lead to serious pollution of soils and/or groundwater. The cumulative beta distribution technique is found to be a versatile and simple technique of gaining valuable information regarding soil heterogeneity effects on solute transport. It is also an excellent tool for guiding future decisions of experimental designs particularly in regard to the number of samples within one site and the number of sampling locations between sites required to obtain a representative estimate of field solute or drainage flux.

Purpose : Which functional tests on mobility and balance can better screen older people at risk of falls is unclear. This study aims to compare the Berg Balance Scale (BBS), Tinetti Mobility Score (TMS), Elderly Mobility Scale (EMS) and Timed Up and Go test (TUG) in discriminating fallers from non-fallers in older people.
Method : This was a case-control study involving one rater who conducted a mobility and balance assessment on subjects using the four functional tests in random sequence. Subjects recruited included 17 and 22 older people with a history of single and multiple falls respectively from a public Falls Clinic, and 39 community-dwellers without fall history and whose age, sex and BMI matched those of the fallers. All subjects underwent the mobility and balance assessment within one day.
Results : Single fallers performed better than multiple fallers in all four functional tests but were worse than non-fallers in the BBS, TMS and TUG. The BBS demonstrated the best discriminating ability, with high sensitivity and specificity. The BBS item 'pick up an object from the floor' was the best at screening fallers.
Conclusion : BBS was the most powerful functional test of the four in discriminating fallers from non-faller.

The diets of four highly-abundant, dominant fish species within the Surrey River, a small intermittently open estuary in south-east Australia, were examined from specimens collected between July 2004 and June 2005. These four, similar-sized species (Atherinosoma microstoma, Galaxias maculatus, Philypnodon grandiceps and Pseudogobius olorum) have limited ability to spatially segregate along the length of the estuary owing to its small size relative to other estuarine habitats. All four species fed on a variety of prey items including crustaceans, insects and detritus. Despite this parity, the four species were demonstrated to occupy differing dietary niches that were concluded to be responsible for reducing interspecific feeding competition. Seasonal variations in the diets were observed for A. microstoma and Philypnodon grandiceps, with these species also exhibiting contrasting diel feeding behaviours. The closure of the estuary mouth led to the flooding of its margins, resulting in an increase in the size of the estuary and providing alternative food resources for the fish to exploit. It appears the inundation of the flood-zone facilitated further significant divergence in the diets of the fish and is likely to be of high ecological value to the estuary.

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches, but some researchers are sounding a note of caution. Evidence is emerging that Australian VET learners are not universally ready for flexible delivery, and this is reflected in high attrition rates and low pass rates. The literature on flexible delivery identifies a number of specific factors that can impact on the success of adult learners. However, there seems to be agreement that failure or dropout is not determined by a single factor, but by the interaction of a number of factors that build up over time. To understand these factors, we need to understand the learners - what their participation in education means to them, the context in which they are studying, and the numerous inter-connected factors that contribute to their failure to achieve a successful outcome. This paper discusses four case studies from a research project that followed up a small number of adult learners who enrolled in flexible delivery VET courses but did not achieve a successful outcome.

As part of a large study of the care of children in Australian, British, Indonesian, and Thai hospitals, qualitative methods were used to examine differences influenced by culture. Two groups were surveyed: parents of hospitalized children, and staff caring for them. Vignettes were used to invoke discussion, and content analysis was used to examine the data. Subjects were interviewed singly, or in focus groups. These interviews were audiotaped and transcribed for analysis. This article is the second of a two-part series, and includes results of the staff's interviews and discussion. The parents' results and discussion were published in Part 1 (Shields [amp ] King, 2001). Staff in all the countries considered communication with parents to be an important part of care of the hospitalized child, and this was consistent with the parents' responses. Staff were mindful of safe practices, though more so in Australia and Britain than Indonesia and Thailand. Cost of treatment for the parents was an important consideration for staff in Indonesia and Thailand when they were planning care for the child. Cultural constructions were more likely to be considered by the Australian and British staff than the Indonesian and Thai staff, and this may have been influenced by the prevailing culture of medical dominance in those countries.

As part of a large study of the care of children in Australian, British, Indonesian, and Thai hospitals, qualitative methods were used to examine differences influenced by culture. Two groups were surveyed: parents of hospitalized children, and staff caring for them. Vignettes were used to invoke discussion, and content analysis was used to examine the data. Subjects were interviewed singly, or in focus groups. These interviews were audiotaped and transcribed verbatim. The data were explored by using content analysis to extract themes of understanding of cultural experiences. This article is the first of a two-part series, and includes a review of the literature, description of the methods used, and results of the parents' interviews. The staff results and discussion will be published in Part 2. Analysis revealed that parents in all countries were primarily concerned with treating the child's illness and the child's recovery. Parents were concerned with their work (employment), but this was a much larger consideration in Indonesia and Thailand, where no social security systems exist, than in Australia and Britain. Communication with staff was the most commonly mentioned theme for parents, indicating that irrespective of the culture in which the care was given, good communication between parents and staff was of paramount importance.
