湘西音乐美术与沈从文创作之关联

沈从文在《从文自传》中说:"我的心总得为一种新鲜声音,新鲜颜色,新鲜气味而跳。"对"声音"和"颜色"的敏感,其实就是音乐和美术的天禀。沈从文在音乐和美术中"倾听"和"观看"到的是湘西各种各样的生命形式,他"试用爱美术音乐的方式来写作","把脑子里与颜色声音分不开的一簇簇印象,转移重现到纸上",构筑一个生命化的艺术世界。     

论撒切尔政府养老金制度改革的动因

在英国养老金制度发展史上,1986年的撒切尔政府养老金制度改革是一次具有重要意义的改革.促成这次改革是多种因素的综合:人口老龄化使养老金支出不断增长;社会保障制度发展与经济发展水平之间的不协调;养老金制度本身的缺陷;哈耶克的思想和货币主义理论对撒切尔的巨大影响;政界的右转.

对我国环境会计基本假设的探讨

当今世界环境问题日益突出,必须大力加强环境保护,这一点已形成共识.但我们不能只用科学技术去解决污染,还必须综合运用经济、法律等措施,实施环境会计就是这其中至关重要的一环.而研究环境会计必须首要解决会计假设的基本理论问题.本文在分析传统会计假设局限性的基础上,提出了相关理论.     

Methodological and conceptual issues confronting a cross-country Delphi study of educational program evaluation

Although the Delphi is widely used, research on certain methodological issues is somewhat limited. After a brief introduction to the strengths, limitations, and methodological challenges of the technique, we share our experiences (as well as problems encountered) with an electronic Delphi of educational program evaluation (EPE) in the Asia-Pacific region. The study is described followed by a discussion of the difficulties in participant recruitment and selection, sample size, instrumentation, data collection and analysis and attempts to resolve them. Some of these problems are generic to the Delphi whereas others related to the specifics of the investigation. What we learned should be useful for future Delphis with a similar focus.     

Role of Gambling Media Exposure in Influencing Trajectories Among College Students

In the study, a model of the relationship between mass media depictions of gambling and subsequent gambling attitudes and behavioral intentions of college students was developed. A survey was conducted with 229 undergraduate students (79.5% female, mean age = 20.5, SD = 2.04) enrolled in three different communication courses at a large southeastern university. Through structural equation analysis, the six hypotheses of this study were analyzed using the method of maximum likelihood with AMOS 6. The model was consistent with the hypotheses that media exposure impacts gambling attitudes and behavioral intentions both positively and negatively, depending on the valence of the gambling depiction. Theoretical and practical implications of mass media exposure and gambling behaviors are discussed, and future research directions are outlined.     

The functional capacity of healthcare workers with history of severe acute respiratory distress syndrome (SARS) complicated with avascular necrosis--case report

Two years after the SARS outbreak in Hong Kong, 128 healthcare workers continued to present with musculoskeletal complaints and 38 workers were diagnosed with avascular necrosis (AVN) in different joints. 13 healthcare workers were referred to six designated Physiotherapy Departments of the Hospital Authority for a tailor-made standardized Functional Capacity Evaluation (FCE) from 2004 to 2005 on a voluntary basis. Job analysis, workers' self-perceived disability and functional capacity, non-material handling tests, and the cardiopulmonary fitness test were performed. Retrospective review of the FCE data showed that there were 17 AVN of hips, 16 AVN of knees, 3 AVN of shoulders. All patients had AVN of lower limb joints. Nearly full ranges of movement (ROM) were observed in the knees involved, but the hip range was decreased for most subjects suffering from hip AVNs. Most workers (n=12) could not complete the cardiopulmonary test due to intolerable joint pain. Six workers' self-perceived physical demands level (PDC) matched with the physical demands level identified by the FCE. 12 healthcare workers attained a sedentary physical demands level and were unable to match with their previous job demands. One staff was classified as light physical demands and managed his original duty. Four workers had returned to work at the time FCE was performed. The tailor-made FCE added information to facilitate the return-to-work planning for the staff. Four more workers returned to work with modified duties one year after the FCE.     

Registered domestic partnerships among gay men and lesbians: the role of economic factors

In this paper, we predict the demand for a marriage-like status—registered domestic partnership–among same-sex couples. Domestic partnership in the state of California now comes with almost all of the rights and responsibilities of marriage that a state can provide. We use the LGBT (Lesbian, Gay, Bisexual, and Transgender) Tobacco Use Survey conducted by the California Department of Health and the Field Research Corporation in 2003. From this telephone survey, we use a probability sample of 1,002 lesbian and gay individuals in California. Using multinomial probit models of partnership status (single, not cohabiting, cohabiting, or registered), we find limited evidence of economic motivations in the choice to register. Gay men’s likelihood of registration rises with income; lesbians’ probability of registration rises with age. Couples with longer duration are more likely to register, suggesting that registration and duration are complementary signals of commitment and possibly of the need for rights and benefits of registration.

A real option theoretic fuzzy evaluation model for enterprise resource planning investment

The high failure rate of ERP implementation is due to a common pitfall that ERP projects are often enacted as merely investment into installation of IT infrastructure, rather than systematic planning of operation changes, business process re-engineering and a paradigm shift for the operation and management. To manage ERP investment in a changing environment for high payoff, this paper adopts a real option theoretic method. Fuzzy payoff valuation is introduced to deal with uncertainties in order to minimize the risk of failure. The proposed ERP evaluation model is geared towards small and medium enterprises. A case study is presented to validate the proposed fuzzy real options. The results indicate the potential of modeling ERP investment as “Expand”, “Contain” and “Abandon” options in different scenarios. The fuzzy real option model bestows a novel ex-ante cost analysis for justifying ERP investment in the implementation cycle.     

具有最优学习率的RBF神经网络及其应用

传统固定学习率的RBF神经网络在金融时间序列预测方面已经有比较成功的应用,但网络学习率的选择问题却给传统RBF神经网络的使用带来了不便.利用梯度下降法及优化方法推导出了RBF神经网络的动态最优学习率并将其应用于网络学习算法,具有最优学习率的RBF神经网络能够在保证网络稳定学习的同时兼顾网络的收敛速度.为了检验具有动态最优学习率的RBF神经网络的预测效果,对沪深300指数波动率进行了预测实验.实验结果表明,具有动态最优学习率的RBF神经网络比传统的固定学习率的RBF神经网络有着更快的收敛速度,同时也避免了人为选定学习率的不便.
