脉压的大小是反映动脉粥样硬化的一个指标,因此,脉压增宽可以预测心脑血管疾病的发生,脉压预测的脑血管疾病危险的价值大于收缩压和舒张压,并有助于解释以往研究中舒张压与病死率关系不一致的现象.  相似文献

This study not only elucidates how service quality cues and perceived risk are related, but also explores the internal composition of this relationship. Financial and psychological risks found to be affected mainly by reliability and empathy of service quality, whereas functional and social risks are influenced by tangibles cues of service quality. Finally, exactly how demographic variables affect the relationship between service quality and perceived risk is considered, and the family life cycle notably modulates this relationship. People in various stages may perceive different levels of service quality, according to their age, which is a variable in the family life cycle.  相似文献

Two studies tested whether people interpreted verbal chance terms in a self‐serving manner. Participants read statements describing the likelihood of events in their own future and in the future of a randomly chosen other. They interpreted the chance terms numerically. Chance terms were interpreted as denoting a higher probability when they were used to describe the likelihood of pleasant events in one's own future than when they were used to describe the likelihood of pleasant events in someone else's future (Study 1). Similarly, chance terms were interpreted as denoting a lower probability when they were used to describe the likelihood of unpleasant events in one's own future than when they were used to describe the likelihood of unpleasant events in someone else's future (Studies 1 and 2). These differences occurred primarily when the risk statements were threatening. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

Previous research has documented a tendency for people to make more risk‐seeking decisions for others than for themselves in relationship scenarios. Two experiments investigated whether this self–other difference is moderated by participants' self‐esteem and anxiety levels. In Experiment 1, lower self‐esteem and higher anxiety levels were associated with more risk‐averse choices for personal decisions but not for decisions for others. Therefore, participants with lower self‐esteem/higher anxiety showed greater self–other differences in comparison to participants with higher self‐esteem/lower anxiety levels. Experiment 2 demonstrated that this effect was largely mediated by participants' expectations of success and feelings about potential negative outcomes. These results are discussed in the context of “threats to the self,” with a central role played by anxiety and self‐esteem threats in personal decision making but not in decision making for others.

The purpose of the present study was to investigate the relationship between brand names and consumers' perceived risk. Hypotheses dealt with whether the presence of a product's brand name affects consumers' perceived risk towards shopping online; whether the familiarity with a brand name influences consumers' perceived risk; and whether online shoppers and non‐shoppers perceive risk towards shopping online differently. Results indicate that the presence or absence of a product's brand name affects online shoppers' perceived risk, but in the opposite direction to that expected. There was no significant difference between online shoppers' perceived risk vis‐à‐vis brand familiarity; however, online shoppers possessed lower perceived risk than non‐shoppers. Implications and limitations are discussed and recommendations for future research are provided. Copyright © 2004 Henry Stewart Publications Ltd.  相似文献

本文提出了期望差异效应的概念并细致阐述了期望差异效应可能是导致风险沟通障碍的原因。期望差异效应是指处于同一情境中的一方对另一方的期望与另一方自我期望之间的差异。围绕上述问题,研究者在阐述了期望差异效应的含义以及期望差异效应可能的心理表征和认知根源之后,细致分析了期望差异效应的强化因素及其可能导致的风险沟通障碍。有关期望差异效应的研究尚处于起步阶段,界定期望差异效应的心理表征,确定期望差异效应的测量工具,探索期望差异效应的影响因素以及分析期望差异效应与风险沟通障碍的关系等都可以作为未来的研究方向。  相似文献
