An exploratory investigation of the investment information search behavior of individual domestic investors

This paper investigates the information search behavior of individual investors, particularly the roles played by online and offline social networks, and from the perspective of social capital and technology readiness. The paper uses rough sets analysis as the analytical tool. This study shows that despite the popularity of social network websites, the social capital of online community is still low when compared to the offline community. Hence, online communities play a less limited role in investment informational social support. Furthermore, investors with low social capital are often characterized by more intense reliance within narrow subgroups for investment information. Investors, especially those with high-investment risk profile, are truly hybrid information consumers. Investors who are innovative in technology and transact online are likely to be the users of online sources. Young investors are more likely to seek advice from online friends. The interaction effect among investment information sources is explicitly displayed via the rough sets decision rules.

面向STEP—NC的零件可制造性评价方法研究与实现

在零件加工前，对其可制造性进行评价是实现零件智能化加工的一个关键环节。针对STEP—NC新型接口标准引入数控加工后的可制造性评价问题，提出了一种面向STEP—NC数控加工的零件可制造性评价方法。在对STEP—NC数控加工程序中工艺信息描述进行分析的基础上，建立了面向STEP～NC的机床信息模型，阐述了零件的可制造性评价目标，提出了实现零件可制造性评价的具体算法。基于Solidworks三维CAD平台，开发了面向STEP—NC的零件可制造性评价模块，并通过实例对所提方法的可行性与有效性进行了验证。     

Incentive mechanism design of access management policy in affordable housing and analysis

Affordable housing is of much importance for Chinese subsidized housing. However, the implementation of the affordable housing policy is facing several problems. One crucial problem is that the current policy cannot effectively identify high-income applicants who are not qualified to apply for affordable housing. Based on the theory of incentive mechanism design, this paper reveals that the current allocation institution has no incentive compatibility. To remedy this shortcoming, a new model for the management of affordable housing is established. Finally, an example is given to show how the proposed model can help improve the overall process of managing the allocation of affordable housing in China.

Work–family conflict in work groups: Social information processing, support, and demographic dissimilarity.

We used social information processing theory to examine the effect of work–family conflict (WFC) at the work group level on individuals’ experience of WFC. Consistent with hypotheses, results suggest that WFC at the work group level influences individual WFC over and above the shared work environment and job demands. It was also observed that work group support and demographic dissimilarity moderate this relationship. Moderator analyses suggest that work group social support buffers WFC for individuals but is also associated with a stronger effect of work group WFC on individuals’ WFC. Moreover, the work group effect on individuals’ WFC was shown to be stronger for individuals who were demographically dissimilar to the work group in terms of sex and number of dependents. The interpretations and implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Integration of acoustical information in the perception of impacted sound sources: The role of information accuracy and exploitability.

Sound sources are perceived by integrating information from multiple acoustical features. The factors influencing the integration of information are largely unknown. We measured how the perceptual weighting of different features varies with the accuracy of information and with a listener’s ability to exploit it. Participants judged the hardness of two objects whose interaction generates an impact sound: a hammer and a sounding object. In a first discrimination experiment, trained listeners focused on the most accurate information, although with greater difficulty when perceiving the hammer. We inferred a limited exploitability for the most accurate hammer-hardness information. In a second rating experiment, listeners focused on the most accurate information only when estimating sounding-object hardness. In a third rating experiment, we synthesized sounds by independently manipulating source properties that covaried in Experiments 1 and 2: sounding-object hardness and impact properties. Sounding-object hardness perception relied on the most accurate acoustical information, whereas impact-properties influenced more strongly hammer hardness perception. Overall, perceptual weight increased with the accuracy of acoustical information, although information that was not easily exploited was perceptually secondary, even if accurate.
