The research compared three major multi-attribute weight measurement methods using multiple criteria: theoretical validity, predictive performance, and perceived performance. Major findings include (1) all three methods are theoretically valid using the EAM (Equal Weight Averaging Model) as the standard of comparison, (2) EAM outperforms SMART (Simple Multi-Attribute Rating Technique) and SMART outperforms AHP (Analytical Hierarchy Process) in terms of predictive performance, (3) in terms of perceived performance, EAM is considered more difficult and less preferred than AHP, but has equal trustworthiness. The research has demonstrated how self-estimation methods for multi-attribute analysis can be verified and improved theoretically and empirically by using weights and values from the EAM model as a theoretical validity standard. © 1998 John Wiley & Sons, Ltd. 相似文献

In this introductory article we define environmental change strategies (ECS), summarize the primary challenges associated with evaluating ECS, and provide an overview of the methods researchers have employed to begin to address these challenges. This special issue provides a range of examples, from researchers and practitioners in the field, of different approaches for addressing these challenges. These articles present new methods to understand and test how ECS are implemented and propose methods to evaluate their implementation. The content of the articles covers multiple public health issues, including substance abuse prevention, tobacco control, HIV prevention, and obesity prevention. This special issue is intended to build the evidence base for effective ECS, generate compelling discussion, critical analyses, and spur future research that will help improve the implementation and evaluation of ECS. 相似文献

Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se. 相似文献

Community psychology (CP) research on the natural environment lacks a theoretical framework for analyzing the complex relationship between human systems and the natural world. We introduce other academic fields concerned with the interactions between humans and the natural environment, including environmental sociology and coupled human and natural systems. To demonstrate how the natural environment can be included within CP’s ecological framework, we propose an ecological model of urban forest stewardship action. Although ecological models of behavior in CP have previously modeled health behaviors, we argue that these frameworks are also applicable to actions that positively influence the natural environment. We chose the environmental action of urban forest stewardship because cities across the United States are planting millions of trees and increased citizen participation in urban tree planting and stewardship will be needed to sustain the benefits provided by urban trees. We used the framework of an ecological model of behavior to illustrate multiple levels of factors that may promote or hinder involvement in urban forest stewardship actions. The implications of our model for the development of multi-level ecological interventions to foster stewardship actions are discussed, as well as directions for future research to further test and refine the model. 相似文献

We present a programmatic line of experimental studies which focus on the how and when of tacit coordination (i.e., the phenomenon that people can successfully coordinate their decisions without communication). We investigated this phenomenon using different types of economic games (i.e., social dilemmas as well as coordination games). Our studies broadly cover three themes: (a) fairness as a coordination rule, (b) uncertainty and common understanding, (c) social information as a cue. By focusing on these themes we have obtained several new insights on the prerequisites and boundary conditions of tacit coordination. We conclude that tacit coordination is often facilitated by mutual adherence to social norms (e.g., fairness rules, rules of deference, etcetera), but that in order to employ such norms people need sufficient environmental and/or social information. 相似文献

Scientists' practices rely not only on the discursive production of science but also on routine interactions whereby scientists manage their teams and their publics. The metaphor of the theatre helps explain how researchers perform impressions to different audiences. This metaphor can also help analyse how scientists and researchers cooperate in performance teams in order to manage credibility impressions. How are research teams constructed and maintained? How do team members respond to the challenges of coordinating the team and elaborating a common vision given their differences in aims and understandings? From 2005 to 2007 a scientific team worked together in the city of Tuzla, Bosnia and Herzegovina, to develop land remediation measures for coal waste disposal sites. The team was organised around a common front developed through ongoing negotiation and bargaining. Scientists employed different strategies to maintain the team through the development of the project, such as reciprocity, unanimity and bargaining. To accommodate individual views, the common front emphasised the presentation of results and the process of research over its specific content and impact. 相似文献

Perspective change within a single environment is a slow and effortful process. However, little research has addressed perspective change across multiple environments. Using a task-set switching paradigm, subjects judged spatial relationships between target locations from differing perspectives. Response times were longer when successive trials probed different perspectives. However, this cost was greater when perspective was changed within a single environment compared to when it was changed across two environments. This result indicates that the processing of perspective change, and perhaps general spatial reasoning, differs in these two cases. Implications for theories of perspective change and environmental knowledge are discussed. 相似文献

In everyday life we accomplish tasks that require the storage and access of mental representations of different environments that we are not currently perceiving. Past research has suggested that environments are encoded by a series of independent representations that are organized in memory. Three experiments tested this idea further by asking whether multiple representations of environments can be accessed simultaneously. Using a cued task-set switching paradigm, subjects judged spatial relationships between target locations in two familiar environments. Response times were longer when successive trials probed different environments, an effect not due to switching between semantic categories or semantic priming, suggesting that representations of environments are accessed sequentially. Implications for various hypotheses concerning the properties of environmental representations are discussed. 相似文献

Integral Ecology uses multiple perspectives to analyze environmental problems. Four of Integral Ecology's major analytical perspectives (known as the quadrants) correspond to the four divisions of the liberal arts and sciences: fine arts, natural science, social science, and humanities. Integral Ecology also utilizes the analytical perspective provided by the idea of cultural moral development. This perspective helps to reveal how stakeholders at different developmental stages disclose a phenomenon, in this case, a tropical forest that loggers propose to clear-cut. Integral Ecology takes into account all pertinent perspectives, in order to arrive at the best possible solution to environmental problems and conflicts. 相似文献

We describe and empirically investigate a hybrid social dilemma that merges give-some and take-some dilemmas by allowing individuals to choose to either give or to take resources from a shared resource pool. Study 1 finds that (a) group size increases the inequality among group members and the likelihood of creating the public good, while reducing the amount of wasted resources; (b) larger bonuses increase provision rates; and (c) asymmetry in the wealth distribution of the group members induces higher levels of inequality of the final outcomes. Following the logic of appropriateness, players with high (low) endowments were more likely to give toward (take from) the shared resource. Study 2 finds that the tendency of the players with high (low) endowments to give (take) is amplified as the difference between endowment levels increased, and the players’ behavior is correlated with, and predictable from, independent judgments of what is perceived as appropriate. 相似文献
