试论我国城镇住房保障的制度并轨

尝试性地提出住房保障制度并轨的观点,认为这种并轨应该包括短期并轨和长期并轨两个层面.在短期内,应该推进租售并举的经济适用房发展模式,提高租赁型住房保障比重,逐步将租赁型经济适用房、廉租房、公租房并入到租房保障体系;公积金管理实施“准银行式”的模式,实现保障资金的跨区域流动;长期内,应该构建多层次、梯度性、差异性的租房保障体系.同时,推进租房保障资金的准商业化、市场化运行模式,提高保障资金供给的可持续性.     

Comment on “A new simple square root option pricing model”

Câmara A. and Wang Y.‐H. ( 2010 ) introduce a simple square root option pricing model where the square root of the stock price is governed by a normal distribution. They show that their three‐parameter option pricing model can outperform the Black–Scholes option pricing model. We demonstrate that their assumption possesses an internal inconsistency in that the square root of the stock price can take on negative values. We generalize and revise their assumption so that the internal inconsistency can be avoided, and introduce a new square root option pricing model. The difference in option prices calculated from the two models may not be trivial. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark     

Investigating Customer Resistance to Change in Transaction Relationship with an Internet Vendor

Many academics and practitioners have reiterated the importance of online customer retention to ensure long‐term profitability. Consequently, a number of studies have identified various means of customer retention. These studies lay significant emphasis on creating customer loyalty. However, retaining customers, especially in the context of Internet shopping, is very difficult because of the low costs in comparison and switching. Most of the loyalty programs have also shown disappointing results. This study suggests that by tapping on an individual customer's inclination to resist changes in a transaction relationship, an Internet vendor can achieve customer retention. Using status quo bias theory, this study examines customer resistance to change (CRC) as a means of retaining customers in a transaction relationship with the Internet vendor. The empirical study of an Internet bookstore reveals that trust, relative attractiveness, and switching costs together influence CRC. The empirical results also show that CRC and switching costs have positive effects on willingness to pay more. Implications for theory and practice are discussed.     

Interpersonal Relationship,Service Quality,Seller Expertise: How Important Are They to Adolescent Consumers?

Drawing upon social capital theory and psychosocial development theory, this paper argues that a true buyer–seller relationship is a key determinant of favorable consumer behaviors for adolescent consumers of hairstylist services. Other important determinants include quality of the service delivery process (i.e., service quality as measured by the five SERVQUAL factors) and quality of the core service (in this case, the hairstylist's expertise). A survey of 350 adolescent consumers confirms these predictions. It shows that a true interpersonal relationship negatively moderates the positive effects of service quality on consumer satisfaction with, and overall assessment of the hairstylist. This negative moderating effect is labeled resource substitution benefit and the argument made that this is the fourth social capital benefit. The theoretical and practical implications of these findings are discussed. © 2012 Wiley Periodicals, Inc.     

The Impact of In‐Store Greenery on Customers

The incorporation of greenery in retail areas has scarcely been explored in environmental psychology studies. In a 2 × 2 experimental design, the effect of in‐store vegetation on consumer emotions and responses toward the store was studied, considering the moderating role of the information rate of the retail setting. While introducing foliage in the store environment did not evoke feelings of excitement, it was found to elicit pleasure and to reduce stress in a “complex” store interior. Given the impact of pleasure and stress on consumers’ approach/avoidance responses, these findings support the potential of integrating greenery, particularly in “spatially dense” stores.     

Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.     

Renminbi＇s Potential to Become a Global Currency

This paper is a tentative endeavor to delineate the potential of the renminbi to become a global currency. It first analyzes the critical economic, financial and policy attributes that are required to support a currency to gain an international role. It then examines whether China has the potential to acquire these attributes. The paper concludes by offering some provisional observations on the implications for Asia and the global economy, should the renminbi evolve into a world currency in the coming decades.     

应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的研究

[目的]探讨应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的试验条件和阳性对照物8-MOP的合适试验浓度。[方法]观测皮肤光毒性实验仪的UVA光强度与开机时间的关系,并根据测得的光强度平均值计算得出光毒性试验所需的照射时间;用不同浓度的8-MOP进行试验,排除8-MOP的原发性刺激作用,选择适宜的应用浓度进行皮肤光毒性试验;对两个防晒粉底按所选仪器条件进行试验。[结果]照射开始后2-100m in,UVA光强度稳定在4.3-4.4 mW/cm^2,平均值为4.4 mW/cm^2,故试验时的照射时间为38m in;用皮肤光毒性实验仪进行光毒性试验,0.05%8-MOP能引起豚鼠皮肤明显光毒性反应并且不引起原发性刺激反应;相同试验条件下未见两种防晒粉底引起豚鼠皮肤显著光毒性反应。[结论]用皮肤光毒性实验仪进行化妆品皮肤光毒性试验可行、有效。
