A study of data from 85 undergraduate and graduate students involved in church youth groups revealed a significant relationship between degree of religious belief and drug using behavior and attitudes. Highly religious subjects disapproved of drinking alcoholic beverages and used cigarettes and alcohol less than subjects professing lower religiosity. Protestant subjects had more negative attitudes and less personal use of tobacco and alcohol than Catholics. Similar findings pertaining to drug using behavior and attitudes were reported between groups for all other substances.

Treeline ecotone scrub, the suite of tall woody plant communities that bridge the boundary between tall forest and higher altitude open summit heaths, is a rare and little studied transition habitat in the UK. Individual species have recently attracted emergency measures to secure their future, but little is known about the current dynamics of the habitats. This thesis increases knowledge of treeline scrub dynamics, particularly in relation to young plants, and develops an understanding of the management required for future conservation. Climate and land use are the main drivers of treeline scrub dynamics, while land use policy will shape the future land use. This study focussed on three species: Betula nana, Salix myrsinites and Juniperus communis, as representatives of the main scrub communities. Firstly, the range of environmental conditions and the current land uses the species tolerate were surveyed for a large number of sites. This enabled the existing sites to be characterised to inform the selection of potential new sites for restoration. Secondly, experiments tested the response of young plants to the interaction between wind exposure and simulated browsing, and, separately, to over-wintering under snow. No evidence was found to suggest that declining snow cover will adversely affect the species, but while the response of the species to increasing exposure and browsing was complex heavy browsing is likely to limit expansion in the absence of specific management. Finally, a review of current land use policy identified that treeline ecotone scrub was included in existing implementation strategies. However, a survey of the understanding of and attitudes to these habitats by key individuals involved in creating, implementing and influencing policy demonstrated that restoration is unlikely to happen within the current structure, except through the interests of non-governmental organisations with a nature conservation focus.

goals of this study were to modify efficacy and outcome expectancies related to moderate alcohol consumption through written communications and determine subsequent changes in behavioral intentions to consume alcohol. Furthermore, two theoretical models which have attempted to conceptualize the relationships between efficacy and outcome expectancies with regards to their predictive utility were evaluated. The results indicated that outcome and efficacy expectancies related to moderate alcohol use were affected by information specifically targeting them. The results did not find support for the hypothesis that negative and positive outcome information would significantly effect perceived efficacy. Nor were main effects found for efficacy information on either positive or negative outcome expectancies. However, a two-way interaction of negative outcome by efficacy on negative interpersonal outcome expectancies were observed. Subjects who were exposed to low efficacy and low negative outcome information indicated higher expectations that negative outcomes would happen to them if they drank in moderation relative to individuals exposed to high efficacy and low negative outcome information. The study found no support for effects of expectancy information on any of the intentions to drink indices. However, post hoc analyses indicated partial support for the hypothesis that past alcohol use moderates the effects of expectancy information on intentions to consume alcohol. In testing the relative utility of outcome and efficacy expectancies in predicting different indices of alcohol use it was found that efficacy expectancies consistently predicted a significant proportion of variance in subject's future drinks per occasion and future frequency of heavy drinking occasions. outcome expectancies were unable to add to the prediction of future drinks per occasion or future frequency of heavy drinking occasions. Several of the drinking indices assessed in this study were individualized for each subject. The utility of this approach is discussed in the paper. The study's results are interpreted in relation to different theorists conceptualizations of the relationship between outcome and efficacy expectancies and directions for future research are discussed. / Master of Science

High levels of personal car use have negative effects on the environment and on human health. This thesis presents four empirical studies that aimed to develop our knowledge of personal travel choices, focussing on the malleability of attitudes and their sensitivity in relation to specific contexts and goals. The first study (Chapter 2) presents a systematic review and meta-analysis of mechanisms of travel mode choice. The study provides a comprehensive overview of antecedents of car use and non-car use, including sub-group analyses of different contextual factors. Results also highlight the need for standardised measures and consideration of implicit thought processes. The second study (Chapter 3) employs a repertory grid technique to elicit perceptions of seven different transport modes from high mileage car users and non-car users. Comparisons between car users and non-car users highlight potentially effective and ineffective intervention targets. Findings show how sustainable transport might be promoted amongst a portfolio of travel choices. The third study (Chapter 4) utilises qualitative methods to explore the extent to which individuals’ attitude expressions are changeable. The study demonstrates that all participants hold ambivalent and conflicting attitudes, highlighting specific situations in which those attitudes are more likely to be unstable. Two related priming experiments are presented in the final empirical chapter (Chapter 5). Both use survey methodology to investigate whether manipulating the salience of car-use-incongruent goals can lead to more positive attitudes towards and increased willingness to use non-car travel modes. The study confirms that people who are motivated to make changes are a potentially optimal target group for interventions based on subliminal messages. Overall, the research presented in this thesis introduces context sensitivity into the transport literature and offers novel insights into perceptions of a range of travel modes. Recommendations include relevant avenues for future research, findings are discussed in light of implications for transport policy and practice.

Older African American (AA) women are at increased risk for HIV and STDs. The purpose of this quantitative study was to examine the influence of provider-initiated condom use education on condom use among unmarried, heterosexually active AA women aged 50 and over using the constructs of self-efficacy and attitudes of the health belief theoretical model. The relationships between provider education on condom use, condom use self-efficacy, condom use attitudes, and actual condom use were tested individually, and provider education on actual condom use was tested after controlling for condom use self-efficacy and attitudes among 95 study participants recruited primarily from Raleigh-Durham, NC. A 2-tailed sample t test or analysis of covariance was used for analysis. Provider education on condom usage failed to show a benefit with regard to condom usage, condom use self-efficacy, and attitudes toward condom usage. Additionally, women who received provider education on condom use were less likely to use condoms. Possibly these women had a low perception of risk and vulnerability to HIV and STDs, which correlated with lower condom use. The counter intuitive findings could also be related to another variable that was not tested and should spur more research. Results could be used to contribute to the design of an intervention model that specifically addresses the sexual behaviors of older AA women. Results of this study, combined with previous research, can help emphasize the need for improved patient-provider communication so that provider communication produces a more positive outcome and helps limit the spread of HIV and STDs, a limitation that would benefit individuals, whole communities, and the nation.

This research study will clarify with facts and evidence that drinking alcoholic beverages is a social problem in American society. It will also focus on indepth interviews using the laddering technique on a small sample of eight respondents.

The aim of this study was to compare the outputs of two modes of citizen participation, the solicitation of written public input, and mail-back questionnaires, on the basis of the opinions and preferences expressed about ORV use and management at Cape Hatteras National Seashore. This comparative analysis was undertaken in order to gain a fuller understanding of the pitfalls and potentialities of survey research in the citizen participation process. The first of two data sets came from a 1978 survey of CHNS residents and visitors on their views about ORV use and possible management actions at the seashore. The second source of data was derived from a content analysis of the written public input on the ORV use and management issue. The Codinvolve System, which was pioneered by the U.S. Forest Service, was used for the content analysis. A test of the reliability of the coding was conducted to evaluate the coding procedure. A phi-test generated coefficients, which when transformed into chi-square values, revealed that the reliability rate was better than 90.0%. The comparison of the two data sets, the survey results, and the Codinvolve output, focused upon the differences between them with respect to the number and character of expressed opinions. Differences between the public input submitted prior to the release of a controversial National Park Service draft ORV management plan and that received after its release were also analyzed. Due to the general scarcity of comments within the public input, chi-square comparisons between the data sets were not feasible. Instead, comparisons of percentages were used to identify the salient differences. Substantial differences were found between the survey and Codinvolve data sets in both the number and character of expressed opinions. However, no substantial differences were found between the pre-plan public input and the post-plan public input. It was noted that the Park Service’s draft ORV management proposals were mentioned in over three-quarters of the post-plan public input. In conclusion, this study suggested that the solicitation of written public input is not an effective citizen participation technique as it fails to educate the public about the various elements and decision parameters associated with an issue. Furthermore, this citizen participation technique provided very limited data on the opinions and preferences of the affected public about ORV use and management. The possible research which survey research can perform in citizen participation and environmental conflict resolution are also discussed. The addition of a workbook or information manual to a mail-back questionnaire was suggested as a means of endowing this citizen participation technique with an educative element. The need for further research on the design and effectiveness of the combined workbook/mail-back questionnaire approach was stressed. / Master of Science
