Recent evidence suggests that the extent of consumer adoption of ‘green’ products is much less than would be indicated by the enthusiastic opinion poll evidence concerning public attitudes towards environmentally-friendly consumption. This paper reports on an empirical analysis of firms' marketing strategies and their influence on consumer demand for green products. In twenty 2–3 hour interviews with senior managers, four representative groups of markets were analysed household detergents, paper (recycled), petrol (unleaded) and automobile technology (focusing on catalytic converters). According to managers, firms' marketing strategies influenced consumer demand by making green technologies available in the fwst instance. However, barriers to supplying green products that show panty with, or better performance than, conventional technologies constrain pricing and communication efforts Managers stressed that, in the absence of clarity of green products' environmental benefits, product performance and other attributes, not green benefits, remain the main determinants of product preference and choice. Promotions focused much more on consumers than distribution channels, yet channel acceptance and support of green innovations are paramount in facilitating sales. Firms see the costs of generating and promoting desirable green technologies as barriers to diffusion in the immediate future. Legislation and/or economic incentives may help, but manufacturers are not optimistic that future green consumption rates will accelerate. The results also highlight several propositions concerning the discrepancy between consumer environmental concerns and purchasing actions which warrant further testing: there is mis-specification of green products in relation to consumers'needs; there are barriers to perceptions of green products' environmental impact and consumers' free ride due to individual self-interest.  相似文献

Healthcare workers' and students' exposures to blood-borne pathogens during a 1-year period (1997) at a large university academic medical center were analyzed. The university health manages the Blood-Borne Pathogen Post-Exposure Control Program at the university and treats all reported exposures of students, faculty, and staff. Comparative exposure rates for all categories of healthcare workers, the work site where injuries occurred, and the circumstances involved in 298 exposure incidents are outlined. A standardized postexposure prophylaxis protocol provides for definition of the health status of all known source patients and assessment of the potential need for treatment of the exposed clinician. Implications of the study for focusing on improvements in training healthcare workers in proper procedures and the use of personal protective equipment in dealing with blood-borne pathogens are discussed.  相似文献

The effort to understand the meanings of the well-demonstrated linkages between mental health and one's locations in the social structure has commanded a great deal of research attention over the past half century. Following a brief consideration of my early efforts to make a contribution in this regard, some recent and ongoing work is summarized. In concert with important work by others, these findings support the conclusion that differences in exposure to social stress represent a much more critical contingency in mental health and substance use outcomes than has generally been assumed. In addition, reported results indicate that the lifetime experience of multiple adversities is quite common among young people in South Florida and, presumably, elsewhere and the likelihood that the compelling linkage observed between cumulative adversity and risk for psychiatric and substance disorders is causal in nature. It is suggested that the development of interventions in the service of stress prevention or reduction should command a greater proportion of the attention of researchers and interventionists.  相似文献

Some gamblers use a doubling strategy as a way of improving their chances of coming home a winner. This paper reports on the results of a computer simulation study of the doubling strategy and compares the short term and long term results of doubling to gambling with a constant sized bet. In the short term players using a doubling strategy were more likely to win, then lose, however in the long term, the losses suffered by doublers were much greater than that suffered by constant bettors. It is argued that the use of a doubling strategy is related to an incomplete conceptualization of random events sometimes known as the law of averages. A second simulation examined the fate of doubling in an ideal world in which the law of averages was actually true. In this ideal world, doublers were much better off than constant bettors. The relationship of the results to a naive conceptualization of random events is discussed.  相似文献

Results are reported from a preliminary study testing a new technology for survey data collection: audio computer-assisted self interviewing. This technology has the theoretical potential of providing privacy (or anonymity) of response equivalent to that of paper self-administered questionnaires (SAQs). In addition, it could offer the advantages common to all computer-assisted methods such as the ability to implement complex questionnaire logic, consistency checking, etc.. In contrast to Video-CASI, Audio-CASI proffers these potential advantages without limiting data collection to the literate segment of the population. In this preliminary study, results obtained using RTI's Audio-CASI system were compared to those for paper SAQs and for Video-CASI. Survey questionnaires asking about drug use, sexual behavior, income, and demographic characteristics were administered to a small sample (N = 40) of subjects of average and below-average reading abilities using each method of data collection. While the small sample size renders many results suggestive rather than definitive, the study did demonstrate that both Audio- and Video-CASI systems work well even with subjects who do not have extensive familiarity with computers. Indeed, respondents preferred the Audio- and Video-CASI to paper SAQs. The computerized systems also eliminated errors in execution of "skip" instructions that occurred when subjects completed paper SAQs. In a number of instances, the computerized systems also appeared to encourage more complete reporting of sensitive behaviors such as use of illicit drugs. Among the two CASI systems, respondents rated Audio-CASI more favorably than Video-CASI in terms of interest, ease of use, and overall preference.  相似文献

It has long been recognised that deaf people experience barriers to political participation and that notions of citizenship do not take into account the needs of deaf sign language users. In light of an effort at the European level to increase the potential for deaf sign language users to participate in political processes through technology, this paper provides results from a survey study of deaf sign language users across Europe as to their preferences in using Telecommunications Relay Services (TRS), whether they would like to see the establishment of a pan-European multilingual TRS and if they would make use of such a service for the purposes of political participation. Responses from 74 deaf people across 14 European member states confirm that deaf people want to see such a service, and would be willing to use it in order to make contact with European institutions. Therefore, the establishment of such a service has the potential to contribute to improved access to, and increased willingness to engage in, democracy through telecommunications and thus enhance the citizenship status of deaf Europeans, and therefore enhance their political participation and access to information and communication in society.  相似文献

ABSTRACT

This study measured the need for formal alternative modes of transportation among older adults by applying traditional factors of the Behavioral Model. Survey participants who regularly drove were compared to those who could no longer drive. Race/ethnicity and self-reported health were significant predictors of perceived need for transportation services for both groups. However, income and service awareness were significant predictors only for drivers, while family proximity was a significant predictor only for non-drivers. Results suggest the importance of gaining a better understanding of the factors associated with need for senior-focused transportation services to more effectively plan such programs.  相似文献
