Campsite impact monitoring in the temperate eucalypt forests of Western Australia: An integrated approach

asmith@murdoch.edu.au, Amanda Jessica Smith January 2004 (has links)
This study assessed the social and biophysical impacts of camping in the eucalypt forests of southwestern Western Australia. This was an integrated study examining both biophysical and social impacts in designated, developed and informal recreation areas used for camping. Four existing and proposed national parks and a Reserve, comprised of 110 designated and 12 informal campsites, provided the study sites. Previous research has focused on backcountry campsites and trails in wilderness areas in United States. A combined survey approach using multiple indicator ratings and measures was used to assess the biophysical impacts of camping. Adjustments to monitoring procedures used in backcountry areas were made so that the indicators were applicable to designated, developed campsites where a management footprint has been imposed. Visitors were surveyed at the designated campsites to establish how existing recreation opportunities were being used. Further, potential indicators and standards were identified to determine what kinds of social and resource conditions were acceptable to visitors and managers. A rating system was then developed combining biophysical and social indicators of importance to visitors and managers with their perceptions of acceptable change obtained from the surveys. Based on the indices derived from the rating system and results for a suite of associated indicators, designated campsites were significantly less impacted than informal ones. For both campsite types the amount of tree damage and litter exceeded the standards set by 50% of visitors and managers. Both visitors and managers were generally more concerned about biophysical impacts than they were about social ones, although site cleanliness was of concern. Both were generally satisfied with the size and number of groups encountered, in contrast to study findings from the United States. This study has developed and successfully applied an integrated approach to monitoring the impacts of recreational use on forested campsites in southwestern Australia. This system effectively and efficiently uses a combination of multiple indicator ratings and measures to produce an impact index, plus social surveys to provide information on conditions, indicators and standards of importance to managers and visitors. It also provides a means for the first time, of objectively monitoring designated, developed campsites where it is inappropriate to judge impacts against an undisturbed control.

Acting Your Age: A Study of the Relationship between Online Social Interaction and Identity in Older Adults

P.T.Dell@curtin.edu.au, Peter Thorlai Dell January 2008 (has links)
This study combined quantitative and qualitative methods to investigate the relationship between Internet use and identity, particularly age-identity, in older Internet users. It has a theoretical basis in symbolic interactionism – particularly the theories of Erving Goffman – and conceptualizes identities as roles that are negotiated during social interaction. The focus on older users was motivated by the strong focus of prior Internet research on younger users. Few studies have examined older users specifically, and fewer still have examined age-identity. Thus, the focus in this study is on how changes in social interaction that occur due to Internet use affect the identity negotiation process. The research is focused around two key areas: whether older users experience the same kinds of online identity processes as younger users, and the impact exposure to novel audiences has on identity negotiation. The study consists of two phases. In the first, a quantitative survey was administered in which a measure of age-identity was assessed and compared with measures of audience novelty. Results showed that a significant increase in variance of ageidentity is associated with communication with people from other countries. This finding supports the theory that identity is formed in negotiation with the audience with whom one communicates, and that expanding this audience may lead to identity effects. To investigate this issue more deeply, a qualitative phase was conducted in which participants were interviewed using rapid ethnography techniques, and at the conclusion of which a model of the interaction between age-identity and Internet communication was developed. This model was then verified with follow-up interviews with key informants and with field observations from sites of online social interaction among seniors. The model developed during the qualitative stage identifies three ways in which ageidentity is influenced by social interaction on the Internet. First, the Internet is used in response to emotional or practical consequences of ageing. Second, older Internet users could take advantage of the ability to manage their personal front online to achieve agelessness, and third, the Internet is used as a backstage area to discuss ageidentity issues. The context of these claims is all-important; each individual’s unique circumstances, emotions and motivations influence the way in which they will use the Internet and respond to others encountered through it. The extension of Goffman’s dramaturgical metaphor to age- identity on the Internet and to include the concept of character development, in which identity evolves over time in response to inner tensions and external events, is a tentative but powerful finding. It poses a challenge for future research into the nature of identity change, both online and offline.
