Anticipated Regret,Risk Perception,or Both: Which is Most Likely Responsible for Our Intention to Gamble?

The current study investigated whether risk aversion or regret aversion could be related to a lower intention to gamble, and whether the type of gambling was a moderator of this relationship. The study took place in Macau, often called “the Las Vegas of East Asia.” A total of 373 Macau residents completed a questionnaire survey dealing with thirteen types of gambling. The results showed that risk perception and anticipated regret had a significant negative effect on the intention to gamble. This negative effect was domain-specific, varying with the type of gambling. Our findings indicated that neither risk aversion nor regret aversion can uniquely explain an individual’s risk-taking tendency consistently. Instead, which factor plays a greater role in lowering the intention to gamble—regret aversion, risk aversion, or both—is itself dependent on the type of gambling involved. The finding that not all gambles are created equal could be useful in gambling prevention and advertising appeal by providing a basis for understanding the role that cognitive and emotional factors play in different types of gambling.     

小波神经网络应用于电子政务信息系统安全风险评估

针对电子政务信息系统风险评估的复杂性和不确定性,作者提出了小波神经网络评估方法,建立了小波神经网络评估模型,最后采用Matlab7.1工具进行了仿真实验,并分别从网络的收敛速度、训练精度和训练效果上与BP神经网络算法作了对比。结果证实该方法有效克服了传统方法中人为分配权重带来的主观性,使评价结果更科学,更合理。

思想政治教育的和谐之维

思想政治教育和谐是以思想和谐为目标通过思想矛盾运动来达到新的思想和谐的过程。思想的交流、思想政治教育与其他工作的交往是思想政治教育的两种状态，它们既存在着矛盾又追求着协调，共同构成思想政治教育的和谐本性。思想政治教育和谐是人类思想发展的客观现象，也具有时代特征，思想政治教育应随着社会条件、时代特征和目标任务的变化，及时改变自己的内容和方式，努力做到适应社会并发挥积极作用。     

文化外交的独特价值

在现代国际关系中,文化外交发挥着政治、经济和军事等对外交往手段难以达到的作用。文化外交是促进民族国家间了解与合作的重要途径,是一国塑造国际形象的重要方式,文化外交成为国际经济竞争与合作的重要资源,它对提升一国的国际竞争力发挥着重要作用,因此具有其独特价值。我国要重视并不断加强文化外交,提升我国的文化影响力,增强文化竞争力,以更好地服务于我国和平发展的需要,推进“和谐世界”的构建。     

要做好常规年度县级GDP核算

一、当前县级GDP核算中存在的问题从总体上来讲,县级GDP核算的第一、二、三产业,涉及20个门类、95个行业大类、396个行业中类,913个行业小类。不同行业、不同规模单位的指标设置对GDP核算满足程度不一的问题,许多GDP核算构成指标在有些部门上没有体现,主要表现在工会经费、福利     

《伪君子》人物出场的探析

《伪君子》是十七世纪的戏剧家莫里哀最优秀的喜剧，在整个戏剧史上具有举足轻重的地位。不论在思想上还是在艺术上都堪称佳作，尤其先声夺人、姗姗来迟、浓妆淡抹、层层张开等人物的出场更是对传统戏剧结构的创新。     

Bayesian mixture models for complex high dimensional count data in phage display experiments

Summary.  Phage display is a biological process that is used to screen random peptide libraries for ligands that bind to a target of interest with high affinity. On the basis of a count data set from an innovative multistage phage display experiment, we propose a class of Bayesian mixture models to cluster peptide counts into three groups that exhibit different display patterns across stages. Among the three groups, the investigators are particularly interested in that with an ascending display pattern in the counts, which implies that the peptides are likely to bind to the target with strong affinity. We apply a Bayesian false discovery rate approach to identify the peptides with the strongest affinity within the group. A list of peptides is obtained, among which important ones with meaningful functions are further validated by biologists. To examine the performance of the Bayesian model, we conduct a simulation study and obtain desirable results.
