Using quantitative influence diagrams to map natural resource managers’ mental models of invasive species management

Despite the significant effect that invasive species have on natural values, the number and extent of invasions continue to rise globally. At least three dominant reasons explain why policy development and implementation can fail: differences in managers’ mental models of invasive species management; cross-agency responsibility; and poor planning and management (i.e., planning–implementation gap). We used a case study of cross-agency management of gamba grass (Andropogon gayanus) in Australia to explore the differences in organizational staffs’ mental models of management. The gamba grass invasion in northern Australia is continuing to expand and associated effects are increasing; coordinated action across agencies is needed to manage the expansion. Our aim was to examine how staff would represent their mental models as a diagram that we could compare between individuals and groups. We used cognitive mapping techniques to elicit models of 15 individuals from across 5 organizations, represented as an influence diagram, which shows the interrelationships that define a system. We compiled the individual influence diagrams to create a team model of management that captures the common connections across participants’ diagrams. The team model revealed that education, science, legislation, enforcement and property management plans were perceived to be the most important management tools to control or eradicate gamba grass. The Weed Management Branch was perceived to have the most central role in gamba grass management, while other organizations were perceived to have specific roles according to their core business. Significant positive correlations (i.e., shared perceptions) were observed across half of the participants, indicating that the some participants have shared models that could be used as a starting point for discussing the team model, clarifying roles and responsibilities, and potentially building consensus around a shared model. Dominant opportunities for improvement identified by participants were better use of management tools, namely education and enforcement, better coordination and collaboration between agencies and increased resourcing. Our research demonstrates the value and validity of using influence diagrams to explore managers’ mental models and to create a team model that could serve as a starting point for improved cross-agency natural resource management.     

Festival attributes and perceptions: A meta-analysis of relationships with satisfaction and loyalty

Festivals provide economic, social and cultural benefits to the communities in which they occur, and contribute to event tourism and destination marketing. This research reports a meta-analysis of the festival literature to evaluate the factors that contribute to festival satisfaction and loyalty. Attributes were classified into six categories: activities, authenticity/uniqueness, concessions, environment, escape and socialization. The analysis revealed that festival activities (program, entertainment, thematic activities) and environment (atmosphere, convenience, facilities) are the most important determinants of satisfaction and loyalty. Two perceptions were evaluated: cost/value and service quality. The analysis revealed that cost/value is important for both satisfaction and loyalty, whereas service quality is relatively unimportant. Satisfaction with the festival is strongly related to loyalty. The findings suggest that festival planners should focus on providing an enjoyable program in a comfortable environment at a reasonable price. This strategy will cultivate repeat attendance and stimulate future visits to the festival destination.     

The moderating influence of style of information processing on media perceptions and information exposure

This study investigated the extent to which style of information processing relates to media perceptions and information exposure. The results showed that visually oriented individuals were more favourably predisposed to the television medium and reported greater exposure to this medium than verbally oriented individuals. Verbally oriented individuals reported greater exposure to print media information than did visually oriented individuals. An exploratory interaction hypothesis between information processing style and gender was not supported. The implications of these results and future research directions are discussed.

Visitor perceptions of crime-safety and attitudes towards risk: The case of Table Mountain National Park,Cape Town

This paper investigates tourist perceptions of crime-safety and attitudes towards risk whilst visiting Table Mountain National Park (TMNP) in Cape Town in June and July 2008. The study examined survey data of 303 domestic and international tourists during their visit to TMNP. A linear regression analysis revealed that although visitors had concerns about their personal safety they are still likely to return to TMNP and recommend it to other people. In addition, visitor attitudes towards risk did not influence perceptions of crime-safety and its effect on their intentions to revisit or recommend TMNP. The results also show that respondent's individual characteristics such as age, nationality, and purpose of visit influenced their perceptions of crime-safety. Perceptions that TMNP is unsafe tended to increase with respondent's age. Respondents on holiday were more likely to perceive TMNP as safer than those on business or visiting friends and relatives. The study's findings add to the literature by offering more insight on tourist perceptions of crime-safety and attitudes towards risk and their impact on tourist behaviour. Various tourist-crime prevention measures to enhance visitor safety at national parks are also recommended to the tourism industry and law enforcement agencies.     

Managerial perspectives on trade and consumer promotions

Understanding the perceptions of managers and the behavioral rules they employ in allocating marketing resources is important in applied research. Using survey data obtained from brand managers, this paper explores the factors managers consider important in allocating trade and consumer promotions. Importance scores on several dimensions are factor analyzed to extract the underlying factors. Indices are computed using these raw scores. The extent of mediation by several brand and category variables on managerial perceptions are then examined by correlating managers' indices and the structural variables. The impact of the structural variables and the importance scores are related to promotion to sales ratios in a regression model. While the structural variables have strong and predictable impact, the importance scores are somewhat weak in their explanatory power. These results are used to shed some light on the budgeting process of allocating marketing dollars among advertising trade and consumer promotions.     

Corruption perceptions vs. corruption reality

This paper examines the accuracy of corruption perceptions by comparing Indonesian villagers' reported perceptions about corruption in a road-building project in their village with a more objective measure of ‘missing expenditures’ in the project. I find that villagers' reported perceptions do contain real information, and that villagers are sophisticated enough to distinguish between corruption in a particular road project and general corruption in the village. The magnitude of the reported information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. I also find that there are biases in reported perceptions. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption.     

An exploratory study of the impact of intervening variables on student performance in a Principles of Accounting course

The purpose of this paper is to provide some new empirical evidence on the determinants of student performance in a Principles of Accounting course at Birzeit University situated in the Occupied West Bank. It examines the impact of a number of new attitudinal variables on examination performance. The empirical results suggest that, in addition to a number of standard control variables, student perceptions of factors associated with class size, the attributes of the lecturer, student effort and the complexity of the course are associated with student performance in a first level principles of accounting course.     

Australian evidence on student expectations and perceptions of introductory business finance

This study examines the differences in perceptions and expectations between students at the Caulfield and Peninsula campuses of Monash University with different entrance criteria and degree availability to determine whether two different introductory finance subjects should be offered rather than one. Results reported in this study suggest that students at the Caulfield campus are interested in studying a challenging introductory finance subject, whereas students at the Peninsula campus perceived that introductory finance is ‘difficult’. Capital structure and cost of capital topics are statistically significantly ranked higher by Caulfield students than Peninsula students. The results reported in this study revealed that two different introductory finance subjects would be more effective. The core subject at the finance major campus (Caulfield) follows a traditional structure with more emphasis on finance theory, whereas the new subject at the non‐finance campus (Peninsula) places greater emphasis on applications.     

The use of design practice to teach mathematics and science

Relatively low participation in the hard sciences (mathematics, science, engineering and technology) has become a concern with respect to the capacity of Australia to meet critical infrastructure projects. This problem has its roots in poor student attitudes towards and perceptions about the study of prerequisite subjects including mathematics and science. Perception formation commences early in students’ education where students have claimed that mathematics was not intrinsically useful and was difficult to understand. With this mind, an intervention was planned and implemented in which technology and design practice was used to integrate the study of mathematics so students could produce and explain a useful artefact. The integrated design project included a focus upon instructional and regulatory discourse. Useful integration tools were developed that facilitated positive cognitive discourses such that students demonstrated a functional understanding of mathematical concepts, reported a broader and more applied understanding of the nature of mathematics and a belief that integration had helped them to make more sense of mathematics.
