农村金融的边缘化与制度创新

随着我国正规金融在农村市场的日渐萎缩,农村金融日益陷入边缘化的状态,于是,在许多地区,非正规金融重新活跃起来,不仅成为支撑当地农村经济发展的重要金融力量,而且因其特有的成长环境而得以有效地运行。本文认为,改革农村金融制度安排,不仅要致力于正规金融的发展,而且应当创新地规范和利用各种非正规金融形式,增加农业领域的信用手段,多渠道地解决农村经济发展中的融资难问题。     

Approximation of fractional Brownian sheet by Wiener integral

Causal attributions of dementia among Korean American immigrants

To better understand conceptualizations of dementia, this study explored causal attributions of dementia among 209 Korean Americans, using a self-administered questionnaire in Korean. Findings show that Korean Americans endorsed various causal attributions. Factor analysis yielded 3 dimensions of their attributions including psychological, physical/environmental, and cognitive/social. Bivariate analyses showed that younger age and higher education were related to more physical/environmental attributions, and younger age was related to more cognitive/social attributions. The study provides an understanding of causal attributions of dementia that practitioners need to understand to provide culturally competent practice and highlights a need to customize public education messages by specific ethnic groups.     

华洋变形的不同世界——栏目解说

世界、国际、全球这样的概念,今日几乎成了从官方到民间的口头禅,国人大都耳熟能详。可是,如果真的放到世界和国际的范围内考察,则不难发现,中国人许多习以为常的概念用法,与各国有别,于情理不合,于实事有异。例如世界史的划分,放眼世界各国,或者根本没有所谓的世界史,只有欧洲     

Gender and Disability in Male‐Dominated Occupations: A Social Relational Model

Evidence from male‐dominated sectors points to high levels of disability and the disabling nature of working environments. However, research of this nature assumes a medical model of disability that does not account for the social construction of disability or the lived experiences of disabled employees. Using data from seven focus groups (n = 44) and semi‐structured interviews with professional transport employees with life‐long hidden ‘impairments’, including dyslexia, dyscalculia, dyspraxia, ADD/ADHD and Asperger syndrome (n = 22), this paper explores the lived experiences of men and women working in a sector traditionally dominated by men, the transport industry. Key themes include homosociality, public–private divide and the impact of changing work practices. Further, the data revealed how those with hidden ‘impairments’ in part construct their identities in relation to both non‐disabled colleagues and those considered stereotypically representing disability (wheelchair users). This study furthers understandings of the relationality of gender and disability in the workplace, and the lived experiences of disabled employees.     

高校校园文化德育功能的弱化及提升策略

高校校园文化建设是高校德育工作的有效载体和重要途径。如何发挥校园文化物质环境、制度约束与激励及精神文化的德育功能,提升德育实效,既是当前高校可持续发展的必然要求,也是高校人才培养工作的迫切需要。但近年来,由于受市场经济下多元文化负面作用及灌输式教育忽视学生主体性因素的影响,校园文化的德育功能明显弱化。必须营造优美的校园物质文化,完善合理的校园制度文化,培育高尚的校园精神文化,提升校园文化的德育功能。

RESOURCE PLANNING FOR MULTIPLE PROJECTS *

This paper is concerned with the estimation of the resource requirements to service multiple projects that use many types of resources. It reports on a systematic procedure to determine the low cost levels of these resources, focusing on the two following characteristics: (1) the comparative cost of standard time to overtime in the utilization of these resources for the economical completion of the projects, and (2) the impact of highly expensive equipment in the determination of the economic levels of the manpower resources that combine with the equipment to form a crew. A numerical example is also presented to illustrate the method. Resource planning is of particular interest in the area of multiproject scheduling, since most of the commonly utilized heuristic solution approaches focus on the allocation of a limited set of available resources. In the corporate strategic planning functions, resource planning is particularly important for capital investment, training and development, and procurement scheduling.     

网上顾客转换成本的影响因素及其结果的实证研究

研究表明,顾客转换成本已成为影响顾客忠诚的另一重要因素,尤其在信息技术环境下,顾客转换成本更显重要.本研究首先建立网上顾客转换成本、影响因素与其结果的结构模型,然后根据此模型对我国网上顾客的转换成本影响因素,以及转换成本与顾客忠诚之间的关系进行实证分析,结果发现,不同因素在顾客转换成本的影响上存在差异性,顾客转换成本不同类别对顾客忠诚意向的影响程度也不相同.最后,根据这些研究结果向企业提出顾客忠诚管理的策略性建议.     

A Methodology for More Efficient Tail Area Sampling with Discrete Probability Distributions

Monte Carlo Method is commonly used to observe the overall distribution and to determine the lower or upper bound value in statistical approach when direct analytical calculation is unavailable. However, this method would not be efficient if the tail area of a distribution is concerned. A new method, entitled Two-Step Tail Area Sampling, is developed, which uses the assumption of discrete probability distribution and samples only the tail area without distorting the overall distribution. This method uses a two-step sampling procedure. First, sampling at points separated by large intervals is done and second, sampling at points separated by small intervals is done with some check points determined at first-step sampling. Comparison with Monte Carlo Method shows that the results obtained from the new method converge to analytic value faster than Monte Carlo Method if the numbers of calculation of both methods are the same. This new method is applied to DNBR (Departure from Nucleate Boiling Ratio) prediction problem in design of the pressurized light water nuclear reactor.
