采用计量经济学加权回归模型对2005年1月~2012年7月,共91个月的欧盟、美国和加拿大月度中国制造消费品召回数量之和作为全球中国制造消费品月度召回数量与全球技术贸易壁垒(TBT)月度通报数量的关系进行定量解析.研究结果表明,两者之间存在对数非线性相关性,相关系数R2统计量为0.9825.在该模型中全球中国制造消费品月度召回数量与上月全球中国制造消费品月度召回数量呈正相关性,增长率约26.8%,与当月度TBT和上个月TBT通报数量呈现约79.6%正增长.TBT通报数量对消费品召回数量存在一定的滞后期,可从TBT通报数量来预测全球中国制造消费品召回的变化趋势. 相似文献

消费品安全面临的技术性贸易措施越来越多.本研究采用计量经济学加权回归模型,对2005年1月至2011年5月,共77个月的欧盟、美国和加拿大月度消费品召回数量之和作为全球消费品月度召回数量与全球TBT月度通报数量的关系进行定量解析.研究结果表明,两者之间存在对数非线性相关性,相关系数R2统计量为0.9852.在该模型中全球消费品月度召回数量与上月全球消费品月度召回数量呈正相关性,增长率约83.6%,当月度TBT和上个月TBT通报数量呈现约2.5%负增长.研究表明,国际消费品召回会继续增加,呈现一定的惯性,而技术性贸易措施对消费品召回有一定程度的滞后效应,在一定程度上降低了消费品召回的预期. 相似文献

Consumer products can evoke a wide range of emotional responses. Nevertheless, these responses deviate from the emotions studied in the majority of the emotion literature. Whereas the general emotion literature tends to focus mainly on negative emotions, the emotions elicited by products tend to be mainly positive. Negative emotions concur with action tendencies. They tend to signal events that require immediate responses, because they are vital for survival. In contrast, people will only be persuaded to invest time, effort, and money in acquiring products, if they are likely to generate positive emotions. Apart from being experienced as pleasant, positive emotions also widen the array of thoughts and actions that come to mind and, thereby, contribute to people’s personal skills and resources. To investigate the subtleties of product emotions in more detail, we need additional theories and instruments that are specifically developed to describe, measure, and explain the concerns and appraisals that differentiate between positive emotions typically experienced in human–product relationships. In addition, we would like to determine the consequences for interacting with products: what kinds of behaviors are activated by the different emotions and how do they affect product experiences? 相似文献

Sensory aspects of consumer choices for meat and meat products 总被引:1,自引:0,他引:1
Resurreccion AV 《Meat science》2004,66(1):11-20
The topics discussed in this paper are the changing demand for meat and the factors that influence this demand. These factors include increased health concerns, change in demographics, the need for convenience, changes in the distribution of meat, and price. Finally, the paper covers the meat industry's need for understanding the consumer and the measurement methods used to assess consumer preferences. 相似文献

The indoor environment is an important source of exposure to polybrominated diphenyl ethers (PBDEs), a class of fire retardants used in many household products. Previous attempts to link PBDE concentrations in house dust to consumer products have been hampered by the inability to determine the presence of PBDEs in otherwise similar products. We used a portable X-rayfluorescence (XRF) analyzer to nondestructively quantify bromine concentrations in consumer goods. In the validation phase, XRF-measured bromine was highly correlated with GC/MS-measured bromine for furniture foam and plastic from electronics (n = 29, r = 0.93, p < 0.0001). In the field study phase, the XRF-measured bromine in room furniture was associated with pentaBDE concentrations in room dust in the bedroom (r = 0.68, p = 0.001) and main living area (r = 0.51, p = 0.02). We also found an association between XRF-measured bromine levels in electronics and decaBDE levels in dust, largely driven by the high levels in televisions (r = 0.64, p = 0.003 for bedrooms). For the main living area, predicting decaBDE in dust improved when we included an interaction effect between the bromine content of televisions and the number of persons in the house (p < 0.005), a potential surrogate for television usage. 相似文献

Consumer ratings of overall liking and creaminess were compared using internal preference mapping for a range of liquid dairy products. Two dimensions were found to explain ratings of overall liking. The first dimension was related to dairy flavour notes and the texture attributes of mouthcoating, oily/greasy, slipperiness and viscosity and the second dimension was related to the sweet and sour taste of the products plus a number of off-flavours. The same two dimensions were found for creaminess ratings although dimension two had far less significance. A wide variation in consumer liking was found and four segments were identified through cluster analysis. In contrast, there was a consensus in consumer ratings of creaminess, which was related to the fat content of the products tested. 相似文献

Products containing silver nanoparticles are entering the market rapidly, but little is known about the potential for inhalation exposure to nanosilver. The objectives of this work were to characterize the emissions of airborne particles from consumer products that claim to contain silver nanoparticles or ions, determine the relationship between emissions and the products' liquid characteristics, and assess the potential for inhalation exposure to silver during product use. Three products were investigated: an antiodor spray for hunters, a surface disinfectant, and a throat spray. Products emitted 0.24-56 ng of silver in aerosols per spray action. The plurality of silver was found in aerosols 1-2.5 μm in diameter for two products. Both the products' liquid characteristics and the bottles' spray mechanisms played roles in determining the size distribution of total aerosols, and the size of silver-containing aerosols emitted by the products was largely independent of the silver size distributions in the liquid phase. Silver was associated with chlorine in most samples. Results demonstrate that the normal use of silver-containing spray products carries the potential for inhalation of silver-containing aerosols. Exposure modeling suggests that up to 70 ng of silver may deposit in the respiratory tract during product use. 相似文献
