Consumer Selection of Food-Safety Information Sources 总被引:1,自引:0,他引:1
The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two-thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information-acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies. 相似文献

A three-level growth-curve model was applied to estimate perceived impact growth trajectories, using multi-year data from project and school surveys on outcome and program implementation collected from 59 sites and approximately 1165 participating schools in the Safe Schools and Healthy Students Initiative. Primary interest is to determine whether and how project-level and school-level correlates affect schools’ perceptions of the Initiative's effectiveness over time when the effects of the pre-grant environmental conditions, grant operations, and near-term outcomes are considered. Coordination and service integration, comprehensive programs and activities for early childhood development, and change in school involvement were found to be significant predictors of school-perceived overall impact when the effect of poverty was considered. Partnership functioning, perceived importance of school resources, and school involvement were found to be significant predictors of school-perceived impact on substance use prevention when the effect of poverty was considered. 相似文献

自三聚氰胺事件之后相继发生的一系列国产消费品安全事故,已引起广泛关注。借鉴柯布道格拉斯函数形式构造了一个需求函数理论模型,分析结果表明:国产消费品安全事故会对总消费需求产生挤出效应,导致涉事进口产品结构性替代涉事国产产品。当涉事产品为非刚性需求产品时,涉事产品的需求会被非涉事产品替代;而当其为刚性需求产品时,涉事产品的需求会反向替代非涉事产品。并且,涉事进口产品价格上涨将加剧部分负面影响。对属于刚性需求的婴幼儿奶粉的问卷调查,进一步实证了理论模型的分析结果。 相似文献

合同语言的歧异性之普遍存在决定了合同解释的普遍性。合同语言的公平、效率和安全等内在价值,则规定了合同解释必须遵循这种价值基础;而合同语言的内在秩序也只有在合同解释的客观主义中才能够得到最好的说明。 相似文献

Summary. Risk is at the centre of many policy decisions in companies, governments and other institutions. The risk of road fatalities concerns local governments in planning countermeasures, the risk and severity of counterparty default concerns bank risk managers daily and the risk of infection has actuarial and epidemiological consequences. However, risk cannot be observed directly and it usually varies over time. We introduce a general multivariate time series model for the analysis of risk based on latent processes for the exposure to an event, the risk of that event occurring and the severity of the event. Linear state space methods can be used for the statistical treatment of the model. The new framework is illustrated for time series of insurance claims, credit card purchases and road safety. It is shown that the general methodology can be effectively used in the assessment of risk. 相似文献

针对《刑法》第137条关于工程重大安全事故罪主体的规定范围略显狭窄的缺陷,提出应当根据我国工程建设的实际情况增加下列主体:将工程建设的相关自然人及人合性组织列入本罪的调整范围;另外,还应当将“勘察单位”、“工程质量监督站”和“施工图审查单位”增列为本罪主体,以利于对本罪的制裁与预防。 相似文献

Through surveys of students and junior professionals and interviews with business and government executives, we studied Chinese choices and fairness perceptions in risky health and safety decisions. The survey responses were compared with American responses from an earlier study by Keller and Sarin.The survey results show that the American and Chinese respondents had similar fairness perceptions, but the Chinese did not make decisions that were consistent with their fairness perceptions, whereas the Americans did. We found that the middle-age Chinese professionals tended to make choices that were more different from the Americans than were the choices of the young Chinese management students. It is likely that these discrepancies were caused by cultural differences, with the younger Chinese tending to face a stronger Western influence.The insights from the survey results were enriched by interviews that revealed fairness perceptions of Chinese business and government executives. A framework to interpret cultural influences on decision making was also proposed. 相似文献

战后以来韩国对日外交经历了几次大抉择,如今韩国正面临对日本外交的新抉择。面对久拖不解的朝核问题和朝鲜的威胁等因素,韩日暂时搁置其矛盾在军事上谋求新的合作,并使美日韩同盟更趋紧密。不过,由于韩日军事走近会牵动韩国民众的敏感神经,同时又给东北亚周边国家的关系增加复杂的不利的因素,因此,韩日安全关系很难在短期内发生质的变化。 相似文献
