A quantitative study was conducted in 1998 to investigate differences in perception, knowledge, awareness, and attitude with regard to environmental problems between educated and community groups and to identify human-dimension factors to improve public perception, knowledge, awareness, and attitude in relation to global environmental conservation concerns in developing countries. Educated and community groups in Jakarta were interviewed, and data obtained from a total of 537 males aged 30-49 years were analyzed. The data were evaluated by the chi-squared test and logistic regression was applied after factor analysis. The results show that: (1) The perception, knowledge, awareness, and attitude of educated subjects in regard to regional and global environmental problems were much better than those of subjects in the community group; (2) The highest 'yes' response in the community group was in regard to perception of AIDS (82.9%). Few subjects in the community group knew the effects and the cause or source of environmental problems, however, they were well informed about AIDS (86.4% for effects and 93.9% for cause or source). The conclusions are: (1) subjects in the educated group had better perception, more detailed knowledge, were more aware, and had better attitudes in regard to regional and global environmental problems than those in the community group; (2) more education is needed to develop environmental actions and ethics in developing countries; (3) non-formal environmental education through popular mass media should be used more widely and frequently, and more detailed information on the environment should be provided to literate people by newspapers and other means.  相似文献

Food, Consumer Concerns, and Trust: Food Ethics for a Globalizing Market   总被引:5,自引:4,他引:1  
The use of biotechnology in food productiongives rise to consumer concerns. The term ``consumerconcern' is often used as a container notion. Itincludes concerns about food safety, environmental andanimal welfare consequences of food productionsystems, and intrinsic moral objections againstgenetic modification. In order to create clarity adistinction between three different kinds of consumerconcern is proposed. Consumer concerns can be seen assigns of loss of trust. Maintaining consumer trustasks for governmental action. Towards consumerconcerns, governments seem to have limitedpossibilities for public policy. Under current WTOregulations designed to prevent trade disputes,governments can only limit their policies to 1) safetyregulation based upon sound scientific evidence and 2)the stimulation of a system of product labeling. Ananalysis of trust, however, can show that ifgovernments limit their efforts in this way, they willnot do enough to avoid the types of consumer concernsthat diminish trust. The establishment of a technicalbody for food safety – although perhaps necessary –is in itself not enough, because concerns that relatedirectly to food safety cannot be solved by ``pure'science alone. And labeling can only be a good way totake consumer concerns seriously if these concerns arerelated to consumer autonomy. For consumer concernsthat are linked to ideas about a good society,labeling can only provide a solution if it is seen asan addition to political action rather than as itssubstitution. Labeling can help consumers take uptheir political responsibility. As citizens, consumershave certain reasonable concerns that can justifiableinfluence the market. In a free-market society, theyare, as buyers, co-creators of the market, andsocietal steering is partly done by the market.Therefore, they need the information to co-create thatmarket. The basis of labeling in these cases, however,is not the good life of the individual but thepolitical responsibility people have in their role asparticipants in a free-market. Then, public concernsare taken seriously. Labeling in that case does nottake away the possibilities of reaching politicalgoals, but it adds a possibility.  相似文献

Recently, both consumers and producers ofbiotechnology products have insisted thatcommunication between the two be improved. The formerdemand more democratic participation in the riskassessment process of biotechnology products. Thelatter seek to correct misinformation regardingalleged risks from these products. One way to resolvethese concerns, I argue, is through the use ofbiotechnology labels. Such labeling fosters consumerautonomy and moves toward more participatory decisionmaking, in addition to ensuring that informed consentfrom consumers is maintained. Furthermore, althoughvoluntary biotech-free labeling in lieu of biotechlabels may uphold consumer sovereignty, the latterremains a more effective strategy for achievingethical communication between consumers and producersof biotechnology products.  相似文献

The success of a regulatory regime in decreasing point-source emissions of some harmful chemicals has highlighted the significance of other sources. A growing number of potentially harmful chemicals have been incorporated into an expanding range of domestic household products and are sold worldwide. Tighter regulation has been proposed, and the European Commission has introduced the Regulation on the Registration, Evaluation, and Authorisation of Chemicals to address this concern. However, it is clear that in addition to the regulation, there is a potential to effect change through retailer and consumer attitudes and behaviours. Interviews were conducted with 7 key stakeholder groups to identify critical issues, which were then explored using a public survey questionnaire (1,008 respondents) and 8 subsequent focus groups. The findings demonstrated that the issue of chemicals in products is of concern to consumers for reasons of personal health rather than environmental protection. Key obstacles to the wider purchase of “green-alternative” products included perceived high cost and poor performance, lack of availability of products, and poor information concerning such products. Although improved regulation was seen as part of the solution, consumers must also play a role. It was clear from this study that consumers are not currently able to make informed choices about the chemicals they use but that they would be receptive to moving toward a more sustainable use of chemicals in the future if empowered to do so.  相似文献

基于人因问题在事故控制中的重要性,为规范人员行为,提出将安全生产标准化中逐条评分的思想融入作业安全管理中,以规范员工个人行为。并将员工不安全行为按照诱因的不同,划分为功能性失误、心理性失误、知识性错误、条件限制性错误、主观意识性违章等5种类型。针对不同诱因提出相应的纠正措施。对比这些措施实施前后员工作业行为符合标准规范的比例,研究运行过程对员工行为的影响。结果表明:该方法的实施减少了试验岗位员工的不安全行为,员工行为规范化程度得到提高。  相似文献

基于多群组结构方程模型的绿色价值结构研究   总被引:1,自引:0,他引:1  
绿色价值结构是"人与自然和谐发展"这一价值理念影响下的消费者消费价值观的结构要素。首先回顾了绿色价值结构的相关文献,提出了绿色价值结构的假设模型,设计并开展了以绿色化妆品为主题的面向女性消费者的问卷调查;然后用SPSS13.0对581份有效问卷数据进行了信度和效度检验以及探索性因子分析,并用AMOS17.0对假设模型和调查数据进行了结构方程模型的拟合和检验;最后分析了不同群组消费者的结构方程模型拟合参数的特点。研究结果表明:当前消费者的绿色价值结构主要由消费者的安全价值、环境价值、审美价值和社交价值构成;在这些消费者价值中,年轻消费者群体和低收入消费者群体的安全价值受到绿色价值理念的影响比较突出,高收入水平、高受教育水平以及年龄比较大的消费群体的环境价值受到绿色价值理念的影响比较明显,低学历消费者群体和年轻消费者群体的社交价值则比较容易受到绿色价值理念的影响。  相似文献

通过问卷调查法对甘肃省农村居民的环境知识、环境认知、环境保护参与意愿与行为进行了调查与分析。结果表明,甘肃农村居民总体环境知识欠缺,环境意识薄弱;农村居民环境保护的支付意愿受支付额度的影响,环境行为尚有较大的改善空间;较低的文化素质是引起农村环境问题的主要原因之一。甘肃省新农村建设环境保护应做好以下工作:加大教育力度,提高农村居民的整体素质;加大资金投入,加强环境基础设施建设;改变不合理的生产生活方式,加强各方面的监督和管理。  相似文献
